                               PROSPECTUS SUMMARY

     You should read this prospectus summary together with the more detailed
information contained in this prospectus, including the risk factors and
financial statements and the notes to the financial statements.

                        NEXT LEVEL COMMUNICATIONS, INC.

     We design and market high-speed, high-volume, also known as broadband,
communications equipment that enables telephone companies and other
communications service providers to cost-effectively deliver a full suite of
voice, data and video services over the existing copper telephone wire
infrastructure. Service providers deploying our equipment can either offer
voice, data and video services in a single product offering or offer each
service separately depending on subscriber demand and the service providers'
objectives. We believe that by installing our equipment, telephone companies and
other communications service providers will be able to capitalize on, and
compete effectively in, the market for integrated voice, data and video
services.

     Telephone companies face increasing competition from cable companies that
have recently announced plans to offer traditional voice services, as well as
high-speed data and video services. Telephone companies, however, have been
constrained in their response to this increased competition because the copper
wire infrastructure used by most telephone companies has not been capable of
delivering high-speed data and video services. Telephone companies seeking to
provide broadband services have generally needed to adopt a complex and costly
strategy of installing independent equipment from multiple vendors.

     We believe that our equipment enables telephone companies to effectively
compete with cable companies in the growing data and video markets. Our
equipment is engineered to provide flexibility to enable telephone companies to
cost-effectively deploy multiple services to large numbers of subscribers. Our
products include equipment located at a telephone company's central office, in
the field and at a subscriber's home or business. Telephone companies using our
equipment can generate incremental revenues from their existing subscribers and
respond to competing service offerings. Additionally, our products are
engineered to provide enhanced security for applications such as electronic
commerce.

     Our objective is to be the leading supplier of communications equipment
used by telephone companies to deliver voice, data and video services to their
residential and business customers. To accomplish this objective, we intend to:

     - capitalize on our existing relationships with key regional Bell operating
       companies to increase our sales as they deploy voice, data and video
       services more broadly;

     - expand our sales into new markets by targeting other communications
       providers that use a copper telephone wire infrastructure, including
       local, independent and international telephone companies;

     - maintain and extend our technology leadership to offer new products and
       features that will provide competitive advantages for all of these
       communications service providers; and

     - continue to outsource manufacturing of our products to maintain
       flexibility and reduce costs.

     We commenced operations in July 1994 and recorded our first sale in
September 1997. From inception through September 30, 1999, approximately 82% of
our total revenues were from sales to U S WEST and Bell Atlantic. In 1999, we
also began to sell our equipment to the local, independent and international
telecommunications markets.

     Our principal executive offices are located at 6085 State Farm Drive,
Rohnert Park, California 94928 and our telephone number is (707) 584-6820. Our

     Unless otherwise indicated, the information in this prospectus (excluding
the historical financial statements):

     - assumes that we have completed our recapitalization as described in this
       prospectus under the heading "Our Recapitalization;" and

     - assumes no exercise of the underwriters' over-allotment option.


     In addition, the number of shares of common stock to be received by General
Instrument in our recapitalization is partially dependent upon an assumed
initial offering price of the common stock of $18.00 per share. A change in the
number of shares of common stock to be received by General Instrument in our
recapitalization will result in the same change in the total number of shares of
common stock outstanding after this offering.

                             SUMMARY FINANCIAL DATA

     The following table presents summary historical, pro forma and pro forma,
as adjusted financial data. The information set forth below should be read in
conjunction with the "Pro Forma Selected Financial Data," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the historical financial statements and notes included in this prospectus. The
statement of operations data for the years ended December 31, 1996, 1997 and
1998 and the nine months ended September 30, 1999 and the balance sheet data as
of September 30, 1999 are derived from audited financial statements included in
this prospectus. The statement of operations data for the nine months ended
September 30, 1998 are derived from the unaudited financial statements included
in this prospectus and include all adjustments (consisting of normal recurring
items) that management considers necessary for a fair presentation of the
financial statements.


     The unaudited pro forma statement of operations data for the year ended
December 31, 1998 and the nine months ended September 30, 1999 give effect to
our recapitalization as if it occurred on January 1, 1998. The pro forma
statement of operations data do not give effect to the non-cash compensation
expense associated with employee stock options to be recorded upon completion of
this offering. The compensation expense, based upon an assumed initial offering
price of $18.00 per share and assuming no forfeitures, will be approximately
$88.5 million, approximately $84.2 million of which will be expensed in the
period in which this offering is completed. This compensation expense excludes
any non-cash compensation expense which may result from the tandem stock option
grant made in January 1997 to some of our employees. The tandem stock option
grant permits these employees to exercise options for either shares of our or
General Instrument's common stock. This non-cash compensation expense would be
an additional $28.2 million, based on an assumed initial offering price of
$18.00 per share, assuming it becomes more likely that all tandem stock option
holders will elect to exercise Next Level options.



     The unaudited pro forma balance sheet data give effect to our
recapitalization as if it occurred on September 30, 1999. The unaudited pro
forma, as adjusted balance sheet data further give effect to our receipt of the
estimated net proceeds from the sale of 8,500,000 shares of common stock in this
offering at an assumed initial public offering price of $18.00 per share, after
deducting underwriting discounts and commissions and estimated offering expenses
payable by us, as if this offering had been completed on September 30, 1999.


     The pro forma and pro forma, as adjusted financial data do not necessarily
represent what the operating results or financial position would have been or
project the operating results or financial position for any future period or
date.

                                  RISK FACTORS

     You should carefully consider the following risks before making an
investment decision. You should also refer to the other information set forth in
this prospectus, including our financial statements and the related notes.

               RISKS RELATED TO FINANCIAL ASPECTS OF OUR BUSINESS

WE HAVE INCURRED NET LOSSES AND NEGATIVE CASH FLOW FOR OUR ENTIRE HISTORY, WE
EXPECT TO INCUR FUTURE LOSSES AND NEGATIVE CASH FLOW AND WE MAY NEVER ACHIEVE
PROFITABILITY

     We incurred net losses of $59.9 million for the nine months ended September
30, 1999, $81.7 million for the year ended December 31, 1998, $66.4 million for
the year ended December 31, 1997 and $173.9 million for the year ended December
31, 1996. Our ability to achieve profitability on a continuing basis will depend
on the successful design, development, testing, introduction, marketing and
broad commercial distribution of our broadband equipment products.

     We expect to continue to incur significant product development, sales and
marketing, and administrative expenses. In addition, we depend in part on cost
reductions to improve gross profit margins because the fixed-price nature of
most of our long-term customer agreements prevents us from increasing prices. As
a result, we will need to generate significant revenues and improve gross profit
margins to achieve and maintain profitability. We may not be successful in
reducing our costs or in selling our products in sufficient volumes to realize
cost benefits from our manufacturers. We cannot be certain that we can achieve
sufficient revenues or gross profit margin improvements to achieve
profitability.

OUR LIMITED OPERATING HISTORY MAKES IT DIFFICULT FOR YOU TO EVALUATE OUR
BUSINESS AND PROSPECTS

     We recorded our first sale in September 1997. As a result, we have only a
limited operating history upon which you may evaluate our business and
prospects. You should consider our prospects in light of the heightened risks
and unexpected expenses and difficulties frequently encountered by companies in
an early stage of development. These risks, expenses and difficulties, which are
described below, apply particularly to us because the market for equipment for
delivering voice, data and video services is new and rapidly evolving. Due to
our limited operating history, it will be difficult for you to evaluate whether
we will successfully address these risks.

WE EXPECT OUR QUARTERLY REVENUES AND OPERATING RESULTS TO FLUCTUATE AND THESE
FLUCTUATIONS MAY MAKE OUR STOCK PRICE VOLATILE

     Our quarterly revenues and operating results have fluctuated in the past
and are likely to fluctuate significantly in the future. As a result, we believe
that quarter-to-quarter comparisons of our operating results may not be
meaningful. Fluctuations in our quarterly revenues or operating results may
cause volatility in the price of our stock. It is likely that in some future
quarter our operating results may be below the expectations of public

                                        6
<PAGE>   11

market analysts and investors, which may cause the price of our stock to fall.
Factors likely to cause variations in our quarterly revenues and operating
results include:

     - delays or cancellations of any orders by U S WEST, which accounted for
       approximately 61% of our revenues for the nine months ended September 30,
       1999, or by any other customer accounting for a significant portion of
       our revenues;

     - variations in the timing, mix and size of orders and shipments of our
       products throughout the quarter or year;

     - new product introductions by us or by our competitors;

     - the timing of upgrades of telephone companies' infrastructure;

     - variations in capital spending budgets of telephone companies; and

     - increased expenses, whether related to sales and marketing, product
       development or administration.

     The amount and timing of our operating expenses generally will vary from
quarter to quarter depending on the level of actual and anticipated business
activity. Because most of our operating expenses are fixed in the short term, we
may not be able to quickly reduce spending if our revenues are lower than we had
projected and our results of operations could be harmed.

BECAUSE OUR SALES CYCLE IS LENGTHY AND VARIABLE, THE TIMING OF OUR REVENUE IS
DIFFICULT TO PREDICT AND WE MAY INCUR SALES AND MARKETING EXPENSES WITH NO
GUARANTEE OF A FUTURE SALE

     Customers view the purchase of our products as a significant and strategic
decision. As a result, customers typically undertake significant evaluation,
testing and trial of our products before deployment. This evaluation process
frequently results in a lengthy sales cycle, typically ranging from six months
to more than a year. Before a customer places an order, we may incur substantial
sales and marketing expenses and expend significant management efforts. In
addition, product purchases are frequently subject to unexpected administrative,
processing and other delays on the part of our customers. This is particularly
true for customers for whom our products represent a very small percentage of
their overall purchasing activities. As a result, sales forecasted from a
specific customer for a particular quarter may not be realized in that quarter
and this could result in lower than expected revenues.

WE MAY NOT BE ABLE TO OBTAIN SUFFICIENT FINANCING TO FUND OUR BUSINESS AND, AS A
RESULT, WE MAY NOT BE ABLE TO GROW AND COMPETE EFFECTIVELY

     In the past, we have relied on General Instrument to provide capital, but
it will not provide us additional funds after this offering. We may need to
raise additional funds if our estimates of revenues or capital requirements
change or prove inaccurate. If we cannot raise these funds, we may not be able
to grow our business. We may need additional capital if we need to respond to
unforeseen technological or marketing hurdles or if we desire to take advantage
of unanticipated opportunities. In addition, we expect to review potential
acquisitions that would complement our existing product offerings or enhance our
technical capabilities that could require potentially significant amounts of
capital. Funds may not be available at the time or times needed on terms
acceptable to us, if at all. If

                                        7
<PAGE>   12

adequate funds are not available, or are not available on acceptable terms, we
may not be able to take advantage of market opportunities, to develop new
products or to otherwise respond to competitive pressures effectively.

                         RISKS RELATED TO OUR CUSTOMERS

OUR CUSTOMER BASE OF TELEPHONE COMPANIES IS EXTREMELY CONCENTRATED AND THE LOSS
OF OR REDUCTION IN BUSINESS FROM EVEN ONE OF OUR CUSTOMERS COULD CAUSE OUR SALES
TO FALL SIGNIFICANTLY

     A small number of customers have accounted for a large part of our revenues
to date. We expect this concentration to continue in the future. If we lose one
of our significant customers, our revenues could be significantly affected. U S
WEST accounted for 68% of total revenues for the year ended December 31, 1998
and 61% of total revenues for the nine months ended September 30, 1999. Bell
Atlantic accounted for 20% of total revenues for the year ended December 31,
1998 and 14% of total revenues for the nine months ended September 30, 1999. Our
agreements with our customers are cancelable by these customers on short notice,
without penalty, do not obligate the customers to purchase any products and are
not exclusive. Accordingly, we may lose revenue from our significant customers
at any time.

A SIGNIFICANT MARKET FOR OUR PRODUCTS MAY NOT DEVELOP IF TELEPHONE COMPANIES DO
NOT SUCCESSFULLY DEPLOY BROADBAND SERVICES SUCH AS HIGH-SPEED DATA AND VIDEO

     Telephone companies have just recently begun offering high-speed data
services, and most telephone companies have not offered video services at all.
Unless telephone companies make the strategic decision to enter the market for
providing broadband services, a significant market for our products may not
develop. Sales of our products depend on the increased use and widespread
adoption of broadband services and the ability of our customers to market and
sell broadband services, including video services, to their customers. Certain
critical issues concerning use of broadband services are unresolved and will
likely affect their use. These issues include security, reliability, speed and
volume, cost, government regulation and the ability to operate with existing and
new equipment.

     Even if telephone companies decide to deploy broadband services, this
deployment may not be successful. Our customers have delayed deployments in the
past and may delay deployments in the future. Factors that could cause telephone
companies not to deploy, to delay deployment of, or to fail to deploy
successfully the services for which our products are designed include the
following:

     - industry consolidation;

     - regulatory uncertainties and delays affecting telephone companies;

     - varying quality of telephone companies' network infrastructure and cost
       of infrastructure upgrades and maintenance;

     - inexperience of telephone companies in obtaining access to video
       programming content from third party providers;

                                        8
<PAGE>   13

     - inexperience of telephone companies in providing broadband services and
       the lack of sufficient technical expertise and personnel to install
       products and implement services effectively;

     - uncertain subscriber demand for broadband services; and

     - inability of telephone companies to predict return on their investment in
       broadband capable infrastructure and equipment.

     Unless our products are successfully deployed and marketed by telephone
companies, we will not be able to achieve our business objectives and increase
our revenues.

CONSOLIDATION AMONG TELEPHONE COMPANIES MAY REDUCE OUR SALES

     Consolidation in the telecommunications industry may cause delays in the
purchase of our products and cause a reexamination of strategic and purchasing
decisions by our customers. In addition, we may lose relationships with key
personnel within a customer's organization due to budget cuts, layoffs, or other
disruptions following a consolidation. For example, US WEST, which has announced
a pending merger with Qwest, and Bell Atlantic, which has announced a pending
merger with GTE, are our two largest customers. Any of these factors relating to
consolidation could impair our ability to generate revenues.

GOVERNMENT REGULATION OF OUR CUSTOMERS AND RELATED UNCERTAINTY COULD CAUSE OUR
CUSTOMERS TO DELAY THE PURCHASE OF OUR PRODUCTS

     The FCC is in the process of developing new rules that could force
telephone companies, such as the regional Bell operating companies, to offer
their competitors cost-based access to some elements of their networks,
including facilities and equipment used to provide high-speed data and video
services. These telephone companies may not wish to make expenditures for
infrastructure and equipment required to provide broadband services if they will
be forced to allow competitors access to this infrastructure and equipment.
Although the FCC recently announced that, except in limited circumstances, it
will not require incumbent carriers to offer their competitors access to the
facilities and equipment used to provide high-speed data services, the full text
of the FCC's decision and the new rule have not yet been released. Thus, some
uncertainty still remains as to what the exact rule will be and how it will
apply in any given circumstance. Accordingly, the uncertainties caused by these
regulatory proceedings may cause these telephone companies to delay purchasing
decisions at least until the proceedings and any related judicial appeals are
completed. The outcomes of these regulatory proceedings, as well as other FCC
regulation, may cause these telephone companies not to deploy services for which
our products are designed or to further delay deployment. Additionally,
telephone companies' deployment of broadband services may be slowed down or
stopped because of the need for telephone companies to obtain permits from city,
state or federal authorities to implement infrastructure for products such as
ours. Any delay in deployment of products by our customers could harm our sales.
For a more detailed description of these and other regulatory matters that may
affect our business, see "Business -- Regulation of Customers."

OUR CUSTOMERS AND POTENTIAL CUSTOMERS WILL NOT PURCHASE OUR PRODUCTS IF THEY DO
NOT HAVE THE INFRASTRUCTURE NECESSARY TO USE OUR PRODUCTS

     The copper wire infrastructures over which telephone companies may deliver
voice, data and video services using our products vary in quality and
reliability. As a result, some

                                        9
<PAGE>   14

of these telephone companies may not be able to deliver a full set of voice,
data and video services to their customers, despite their intention to do so,
and this could harm our sales. Even after installation of our products, we
remain highly dependent on telephone companies to continue to maintain their
infrastructure so that our products will operate at a consistently high
performance level. Infrastructure upgrades and maintenance may be costly, and
telephone companies may not have the necessary financial resources. This may be
particularly true for our smaller customers and potential customers such as
independent telephone companies and domestic local telephone companies. If our
current and potential customers' infrastructure is inadequate, we may not be
able to generate anticipated revenues from them.

                         RISKS RELATED TO OUR INDUSTRY

IF COMPETING TECHNOLOGIES THAT OFFER ALTERNATIVE SOLUTIONS TO OUR PRODUCTS
ACHIEVE WIDESPREAD ACCEPTANCE, THE DEMAND FOR OUR PRODUCTS MAY NOT DEVELOP

     Technologies that compete with our system include other
telecommunications-related wireline technologies, cable-based technologies,
fixed wireless technologies and satellite technologies. If these alternative
technologies are chosen by our existing and potential customers, our business,
financial condition and results of operations could be harmed. In particular,
cable operators are currently deploying products that will be capable of
delivering voice, high-speed data and video services over cable, including
products from General Instrument, our principal stockholder. Our technology may
not be able to compete effectively against these technologies on price,
performance or reliability.

     Our customers or potential customers that also offer cable-based services
may choose to purchase cable-based technologies. Cable service providers that
offer not only data and video but also telephony over cable systems will give
subscribers the alternative of purchasing all communications services from a
single communications service provider, allowing the potential for more
favorable pricing and a single point of contact for bill payment and customer
service. If these services are implemented successfully over cable connections,
they will compete directly with the services offered by telephone companies
using our products. In addition, several telephone companies have commenced the
marketing of video services over direct broadcast satellite while continuing to
provide voice and data services over their existing copper wire infrastructure.
If any of these services are accepted by consumers, the demand for our products
may not develop and our ability to generate revenue will be harmed.

WE FACE INTENSE COMPETITION IN PROVIDING EQUIPMENT FOR TELECOMMUNICATIONS
NETWORKS FROM LARGER AND MORE WELL-ESTABLISHED COMPANIES AND WE MAY NOT BE ABLE
TO COMPETE EFFECTIVELY WITH THESE COMPANIES

     Many of our current and potential competitors have longer operating
histories, greater name recognition and significantly greater financial,
technical, marketing and distribution resources than we do. These competitors
may undertake more extensive marketing campaigns, adopt more aggressive pricing
policies and devote substantially more resources to developing new products than
we are able to, which could result in the loss of current and potential
customers.

                                       10
<PAGE>   15

     Our significant current and potential competitors include Advanced Fibre
Communications, Alcatel, Cisco Systems, Efficient Networks, Ericsson, Lucent
Technologies, Nokia, Nortel Networks, RELTEC (recently acquired by GEC Marconi),
Scientific Atlanta, Siemens and our largest stockholder, General Instrument
(which has announced a pending merger with Motorola), as well as emerging
companies that are developing new technologies. Some of these competitors have
existing relationships with our current and prospective customers. In addition,
we anticipate that other large companies, such as Matsushita Electric Industrial
(which markets products under the Panasonic brand name), Microsoft, Network
Computer, Philips, Sony, STMicroelectronics and Toshiba America, will likely
introduce products that compete with our Residential Gateway product in the
future. Our customer base may be attracted by the name and resources of these
large, well-known companies and may prefer to purchase products from them
instead of us.

CONSOLIDATION OF OUR COMPETITORS MAY CAUSE US TO LOSE CUSTOMERS AND NEGATIVELY
AFFECT OUR SALES

     Consolidation in the telecommunications equipment industry may strengthen
our competitors' position in our market, cause us to lose customers and hurt our
sales. For example, Alcatel acquired DSC Communications, Lucent recently
acquired Ascend Communications and GEC Marconi recently acquired RELTEC.
Acquisitions such as these may strengthen our competitors' financial, technical
and marketing resources and provide access to regional Bell operating companies
and other potential customers. Consolidation may also allow some of our
competitors to penetrate new markets that we have targeted, such as domestic
local, independent and international telephone companies. This consolidation may
affect our ability to increase revenues.

IF WE DO NOT RESPOND QUICKLY TO CHANGING CUSTOMER NEEDS AND FREQUENT NEW PRODUCT
INTRODUCTIONS BY OUR COMPETITORS, OUR PRODUCTS MAY BECOME OBSOLETE

     Our position in existing markets or potential markets could be eroded
rapidly by product advances. The life cycles of our products are difficult to
estimate. Our growth and future financial performance will depend in part upon
our ability to enhance existing products and develop and introduce new products
that keep pace with:

     - the increasing use of the Internet;

     - the growth in remote access by telecommuters;

     - the increasingly diverse distribution sources for high quality digital
       video; and

     - other industry and technological trends.

     We expect that our product development efforts will continue to require
substantial investments. We may not have sufficient resources to make the
necessary investments. If we fail to timely and cost-effectively develop new
products that respond to new technologies and customer needs, the demand for our
products may fall and we could lose revenues.

                                       11
<PAGE>   16

              RISKS ASSOCIATED WITH OTHER ASPECTS OF OUR BUSINESS

OUR EXECUTIVE OFFICERS AND CERTAIN KEY PERSONNEL ARE CRITICAL TO OUR BUSINESS
AND THE LOSS OF THEIR SERVICES COULD DISRUPT OUR OPERATIONS AND OUR CUSTOMER
RELATIONSHIPS

     None of our executive officers or key employees are bound by an employment
agreement. Many of these employees have a significant amount of options to
purchase our common stock. Many of these options are currently vested and are
exercisable upon consummation of this offering and some of our key employees may
leave us once they have exercised their options. In addition, our engineering
and product development teams are critical in developing our products and have
developed important relationships with our regional Bell operating company
customers and their technical staffs. The loss of any of these key personnel
could harm our operations and customer relationships.

COMPETITION FOR QUALIFIED PERSONNEL IN THE TELECOMMUNICATIONS EQUIPMENT INDUSTRY
IS INTENSE, AND IF WE ARE NOT SUCCESSFUL IN ATTRACTING AND RETAINING THESE
PERSONNEL, OUR ABILITY TO GROW OUR BUSINESS MAY BE HARMED

     Competition for qualified personnel in the telecommunications equipment
industry, specifically in the Rohnert Park, California area, is intense, and we
may not be successful in attracting and retaining such personnel. Failure to
attract qualified personnel could harm the growth of our business.

     We are actively searching for research and development engineers and sales
and marketing personnel who are in short supply. Competitors and others have in
the past and may in the future attempt to recruit our employees. In addition,
companies in the telecommunications industry whose employees accept positions
with competitors frequently claim that the competitors have engaged in unfair
hiring practices. We may receive such notices in the future as we seek to hire
qualified personnel and such notices may result in material litigation and
related disruption to our operations.

OUR OPERATIONS AND CUSTOMER RELATIONSHIPS MAY BECOME STRAINED DUE TO RAPID
EXPANSION

     We have expanded our operations rapidly since inception. We intend to
continue to expand in the foreseeable future to pursue existing and potential
market opportunities both inside and outside the United States. This rapid
growth places a significant demand on management and operational resources. Our
management, personnel, systems, procedures, controls and customer service may be
inadequate to support our future operations. To manage expansion effectively, we
must implement and improve our operational systems, procedures, controls and
customer service on a timely basis. We expect significant strain on our order
and fulfillment process and our quality control systems if significant expansion
of business activity occurs. If we are unable to properly manage this growth,
our operating results, reputation and customer relationships could be harmed. As
a result, our stock price could fall.

OUR LIMITED ABILITY TO PROTECT OUR INTELLECTUAL PROPERTY MAY AFFECT OUR ABILITY
TO COMPETE AND WE COULD LOSE CUSTOMERS

     We rely on a combination of patent, copyright and trademark laws, and on
trade secrets and confidentiality provisions and other contractual provisions to
protect our intellectual property. There is no guarantee that these safeguards
will protect our

                                       12
<PAGE>   17

intellectual property and other valuable confidential information. If our
methods of protecting our intellectual property in the United States or abroad
are not adequate, our competitors may copy our technology or independently
develop similar technologies and we could lose customers. In addition, the laws
of some foreign countries do not protect our proprietary rights as fully as do
the laws of the United States. If we fail to adequately protect our intellectual
property, it would be easier for our competitors to sell competing products
which could harm our business.

THIRD-PARTY CLAIMS REGARDING INTELLECTUAL PROPERTY MATTERS COULD CAUSE US TO
STOP SELLING OUR PRODUCTS, LICENSE ADDITIONAL TECHNOLOGY OR PAY MONETARY DAMAGES


     From time to time, third parties, including our competitors and customers,
have asserted patent, copyright and other intellectual property rights to
technologies that are important to us. We expect that we will increasingly be
subject to infringement claims as the number of products and competitors in our
market grows and the functionality of products overlaps, and our products may
currently infringe on one or more United States or international patents. The
results of any litigation are inherently uncertain. In the event of an adverse
result in any litigation with third parties that could arise in the future, we
could be required:


     - to pay substantial damages, including paying treble damages if we are
       held to have willfully infringed;

     - to halt the manufacture, use and sale of infringing products;

     - to expend significant resources to develop non-infringing technology;
       and/or

     - to obtain licenses to the infringing technology.

     Licenses may not be available from any third party that asserts
intellectual property claims against us, on commercially reasonable terms, or at
all. In addition, litigation frequently involves substantial expenditures and
can require significant management attention, even if we ultimately prevail. In
addition, we indemnify our customers for patent infringement claims and we may
be required to obtain licenses on their behalf which could subject us to
significant additional costs.

WE DEPEND ON THIRD-PARTY MANUFACTURERS AND ANY DISRUPTION IN THEIR MANUFACTURE
OF OUR PRODUCTS WOULD HARM OUR OPERATING RESULTS

     We contract for the manufacture of all of our products and have limited
in-house manufacturing capabilities. We rely primarily on two large contract
manufacturers: SCI Systems and CMC Industries. The efficient operation of our
business will depend, in large part, on our ability to have these and other
companies manufacture our products timely, cost-effectively and in sufficient
volumes while maintaining consistent quality. As our business grows, these
manufacturers may not have the capacity to keep up with the increased demand.
Any manufacturing disruption could impair our ability to fulfill orders and
could cause us to lose customers.

                                       13
<PAGE>   18

WE HAVE NO LONG-TERM CONTRACTS WITH OUR MANUFACTURERS AND WE MAY NOT BE ABLE TO
DELIVER OUR PRODUCTS ON TIME IF ANY OF THESE MANUFACTURERS STOP MAKING OUR
PRODUCTS

     We have no long-term contracts or arrangements with any of our contract
manufacturers that guarantee product availability, the continuation of
particular payment terms or the extension of credit limits. If our manufacturers
are unable or unwilling to continue manufacturing our products in required
volumes, we will have to identify acceptable alternative manufacturers, which
could take in excess of three months. For example, Flextronics International,
previously designated to be the sole manufacturer of our ETHERset product,
discontinued its relationship with us due to lack of order volume. It is
possible that a source may not be available to us when needed or be in a
position to satisfy our production requirements at acceptable prices and on a
timely basis. If we cannot find alternative sources for the manufacture of our
products, we will not be able to meet existing demand. As a result, we may lose
existing customers and our ability to gain new customers may be significantly
constrained.

OUR INABILITY TO PRODUCE SUFFICIENT QUANTITIES OF OUR PRODUCTS BECAUSE OF OUR
DEPENDENCE ON COMPONENTS FROM KEY SOLE SUPPLIERS COULD RESULT IN DELAYS IN THE
DELIVERY OF OUR PRODUCTS AND COULD HARM OUR REVENUES

     Some parts, components and equipment used in our products are obtained from
sole sources of supply. If we or our sole source suppliers fail to obtain
components in sufficient quantities when required, delivery of our products
could be delayed resulting in decreased revenues. Additional sole-sourced
components may be incorporated into our equipment in the future. We do not have
any long term supply contracts to ensure sources of supply. In addition, our
suppliers may enter into exclusive arrangements with our competitors, stop
selling their products or components to us at commercially reasonable prices or
refuse to sell their products or components to us at any price, which could harm
our operating results.

THE OCCURRENCE OF ANY DEFECTS, ERRORS, OR FAILURES IN OUR PRODUCTS COULD RESULT
IN DELAYS IN INSTALLATION, PRODUCT RETURNS AND OTHER LOSSES TO US OR TO OUR
CUSTOMERS OR END-USERS

     Our products are complex and may contain undetected defects, errors or
failures. These problems have occurred in our products in the past and
additional errors may occur in our products in the future and could result in
the loss of or delay in market acceptance of our products. In addition, we have
limited experience with commercial deployment and we expect additional defects,
errors and failures as our business expands from trials to commercial deployment
at certain customers. We will have limited experience with the problems that
could arise with any new products that we introduce. Further, our customer
agreements generally include a longer warranty for defects than our
manufacturing agreements. These defects could result in a loss of sales and
additional costs as well as damage to our reputation and the loss of our
customers.

WE DO NOT HAVE SIGNIFICANT EXPERIENCE IN INTERNATIONAL MARKETS AND MAY HAVE
UNEXPECTED COSTS AND DIFFICULTIES IN DEVELOPING INTERNATIONAL REVENUES

     We plan to extend the marketing and sales of our products internationally.
International operations are generally subject to inherent risks and challenges
that could harm our operating results, including:

     - unexpected changes in telecommunications regulatory requirements;

     - limited number of telephone companies operating internationally;

     - expenses associated with developing and customizing our products for
       foreign countries;

     - tariffs, quotas and other import restrictions on telecommunications
       equipment;

     - longer sales cycles for our products; and

     - compliance with international standards that differ from domestic
       standards.

     To the extent that we generate international sales in the future, any
negative effects on our international business could harm our business,
operating results and financial condition as a whole. In particular, fluctuating
exchange rates may contribute to fluctuations in our results of operations.

PROBLEMS RELATED TO THE YEAR 2000 ISSUE COULD HARM OUR PRODUCTS OR OUR
REPUTATION OR CAUSE OUR CUSTOMERS TO DECREASE SPENDING ON OUR PRODUCTS

     Computer systems, software packages and microprocessor-dependent equipment
may cease to function or generate erroneous data when the year 2000 arrives. If
systems material to our business are not year 2000 compliant or if third parties
fail to make their systems year 2000 compliant in a timely manner, the year 2000
issue could affect our operations. The potential areas of exposure include
systems and equipment operated by third parties with which we transact business
and computers, software, telephone systems and other equipment used internally.
Our year 2000 compliance program may not fully address all potential year 2000
problems. Additionally, our customers' purchasing and deployment plans could be
affected by year 2000 issues. Some customers may wait to purchase or deploy our
products, if at all, which may reduce our future revenues. For a discussion of
our year 2000 preparedness program, see "Management Discussion and Analysis of
Financial Condition and Results of Operations -- Year 2000."

                         RISKS RELATED TO THIS OFFERING

GENERAL INSTRUMENT WILL EXERCISE SIGNIFICANT INFLUENCE OVER OUR BUSINESS AND
AFFAIRS AND OUR STOCKHOLDER VOTES AND, FOR ITS OWN REASONS, COULD PREVENT
TRANSACTIONS WHICH OUR OTHER STOCKHOLDERS MAY VIEW AS FAVORABLE


     Upon completion of this offering, General Instrument will beneficially own
approximately 82% of the outstanding shares of our common stock. Although
General Instrument will enter into a voting trust agreement to limit its voting
power to 49% of the voting power of all outstanding common stock and to limit
the number of its designees to the board of directors to one less than a
majority, General Instrument will be able to exercise significant


                                       15
<PAGE>   20

influence over all matters relating to our business and affairs, including
approval of significant corporate transactions, which could delay or prevent
someone from acquiring or merging with us and could prevent you from receiving a
premium for your shares. In addition, General Instrument intends to terminate
the voting trust agreement immediately upon the completion of its pending merger
with Motorola.

AFTER THE COMPLETION OF GENERAL INSTRUMENT'S PENDING MERGER WITH MOTOROLA,
MOTOROLA WOULD THEN CONTROL US AND COULD PREVENT CHANGES THAT MAY BE FAVORABLE
TO US AND TO OUR OTHER STOCKHOLDERS AND IMPLEMENT CHANGES THAT MAY BE ADVERSE TO
US AND TO OUR OTHER STOCKHOLDERS, AND THIS COULD CAUSE OUR STOCK PRICE TO FALL

     On September 14, 1999, General Instrument entered into an agreement and
plan of merger with Motorola, Inc. Immediately upon the completion of this
pending merger, General Instrument intends to terminate the voting trust
agreement and appoint additional individuals to our board of directors
sufficient to exercise control. Accordingly, upon completion of this pending
merger, Motorola will be able to exercise voting power over a majority of our
shares and will have the ability to control our board of directors and all
matters relating to our business and affairs. We do not know whether Motorola's
plans for our business and affairs will be different than our existing plans and
whether any changes that may be implemented under Motorola's control will be
beneficial or detrimental to our other stockholders.

OUR PRINCIPAL STOCKHOLDER MAY HAVE INTERESTS WHICH CONFLICT WITH THE BEST
INTERESTS OF US AND OUR OTHER STOCKHOLDERS AND MAY CAUSE US TO FORGO
OPPORTUNITIES OR TAKE ACTIONS WHICH DISPROPORTIONATELY BENEFIT OUR PRINCIPAL
STOCKHOLDER

     It is possible that General Instrument or Motorola could be in a position
involving a conflict of interest with us. In addition, individuals who are
officers or directors of both us and our principal stockholder may have
fiduciary duties to both companies. For example, a conflict may arise if our
principal stockholder were to engage in activities or pursue corporate
opportunities that may overlap with our business. These conflicts could harm our
business and, as a result, could cause our stock price to fall. Our certificate
of incorporation contains provisions intended to protect our principal
stockholder and these individuals in these situations. These provisions would
limit your legal remedies. For a description of these provisions, see
"Description of Capital Stock -- Other Certificate of Incorporation and By-law
Provisions -- Corporate Opportunities."

     By becoming a stockholder of Next Level, investors will be considered to
have consented to the provisions of our certificate of incorporation, except to
the extent any of the provisions are inconsistent with Delaware law.


OVER 70 MILLION, OR APPROXIMATELY 89% OF OUR TOTAL OUTSTANDING SHARES, ARE
RESTRICTED FROM IMMEDIATE RESALE BUT MAY BE SOLD INTO THE MARKET IN THE NEAR
FUTURE. THIS COULD CAUSE THE MARKET PRICE OF OUR COMMON STOCK TO DROP
SIGNIFICANTLY



     After this offering, we will have outstanding 79,437,902 shares of common
stock. After this offering, General Instrument will own 65,074,573 shares of our
common stock and Spencer Trask will own 5,863,329 shares of our common stock and
its affiliates will hold warrants to purchase an additional 8,480,102 shares of
our common stock. If General Instrument, Spencer Trask or any of our other
stockholders sell substantial amounts of common stock, including shares issued
upon exercise of outstanding options and warrants, in the public market
following this offering, the market price of the common stock could


                                       16
<PAGE>   21

fall. In addition, any distribution of shares of our common stock by General
Instrument to its stockholders could also have an adverse effect on the market
price.

     All shares sold in this offering may be resold in the public market
immediately. All of the remaining shares will be owned by General Instrument and
Spencer Trask and its affiliates. Under federal securities laws, these shares,
unless registered under the Securities Act, generally may be resold in the
public market only following a one-year holding period that will begin to run
upon the completion of our recapitalization and subject to volume and manner of
sale limitations. General Instrument and Spencer Trask and its affiliates will
be entitled to registration rights pursuant to which they may require that we
register their shares under the Securities Act. In addition, each of General
Instrument and Spencer Trask and its affiliates has entered into a lockup
agreement with the underwriters pursuant to which they have agreed generally not
to transfer or dispose of shares of common stock or securities convertible into
common stock for a period of 180 days after the date of this prospectus.
However, these lockups may be waived by Credit Suisse First Boston Corporation.


     In addition, there are outstanding options to purchase 12,358,758 shares of
our common stock. The holders of options to purchase 3,074,794 shares of our
common stock have entered into 365-day lockup agreements with the underwriters,
and the holders of the remaining options have entered into 180-day lockup
agreements. Following completion of this offering, we intend to file with the
SEC a registration statement covering the shares issuable upon the exercise of
our outstanding employee options. Accordingly, subject to vesting provisions
and, in the case of our affiliates, volume and manner of sale restrictions, the
shares of common stock issuable upon the exercise of our outstanding employee
options will be eligible for sale into the public market at various times after
the expiration of the applicable lockup period. The lockups may be waived by
Credit Suisse First Boston Corporation. For a more detailed description, see
"Shares Eligible for Future Sale."


ANTITAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW COULD PREVENT
OR DELAY A CHANGE IN CONTROL OF OUR COMPANY THAT A STOCKHOLDER MAY CONSIDER
FAVORABLE

     Several provisions of our certificate of incorporation and bylaws and
Delaware law may discourage, delay or prevent a merger or acquisition that a
stockholder may consider favorable. These provisions include:

     - authorizing the issuance of preferred stock without stockholder approval;

     - providing for a classified board of directors with staggered, three year
       terms;

     - prohibiting cumulative voting in the election of directors;

     - restricting business combinations with interested stockholders;

     - limiting the persons who may call special meetings of stockholders;

     - prohibiting stockholder action by written consent;

     - establishing advance notice requirements for nominations for election to
       the board of directors or for proposing matters that can be acted on by
       stockholders at stockholder meetings; and

     - requiring super-majority voting to effect amendments to our certificate
       of incorporation and bylaws.

Some of these provisions will not currently apply to General Instrument and its
affiliates. For a more detailed description of these provisions, see
"Description of Capital Stock."

                           FORWARD-LOOKING STATEMENTS

     Some of the statements under "Prospectus Summary," "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business" and elsewhere in this prospectus constitute
forward-looking statements. These statements relate to future events or our
future financial performance. In some cases, you can identify forward-looking
statements by terminology such as "may," "will," "should," "expect," "plan,"
"anticipate," "believe," "estimate," "predict," "potential" or "continue" or the
negative of such terms or other comparable terminology. These statements involve
known and unknown risks, uncertainties, and other factors that may cause our or
our industry's actual results, levels of activity, performance, or achievements
to be materially different from any future results, levels of activity,
performance or achievements expressed or implied by such forward-looking
statements. These factors include, among other things, those listed under "Risk
Factors" and elsewhere in this prospectus.

     Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance, or achievements.

                                USE OF PROCEEDS


     We estimate that through this offering we will receive net proceeds of
$139.5 million ($160.8 million if the underwriters' over-allotment option is
exercised in full), assuming an initial public offering price of $18.00 per
share, and after deducting underwriting discounts and commissions and estimated
offering expenses payable by us. The primary purposes of this offering are to
increase our equity capital, to create a public market for our common stock and
to facilitate future access to public markets. As of the date of this
prospectus, we have no specific plans to use the net proceeds from this offering
other than as set forth below.


     We expect to use the net proceeds of this offering for general corporate
purposes, including working capital and using a currently estimated $55 million
to fund our continued research and development efforts. From time to time we
will evaluate our opportunities to acquire businesses, products and technologies
that complement our business. We may use a portion of the net proceeds from this
offering for these acquisitions. Currently, however, we do not have any
understandings, commitments or agreements with respect to these acquisitions.
Pending our use of the proceeds, we will most likely invest the net proceeds in
short-term, interest-bearing, investment-grade obligations.

                                DIVIDEND POLICY

     We do not expect to pay dividends on our common stock in the foreseeable
future. We anticipate that all future earnings, if any, generated from
operations will be retained to develop and expand our business. Any future
determination with respect to the payment of dividends will be at the discretion
of the board of directors and will depend upon, among other things, our
operating results, financial condition and capital requirements, the terms of
then-existing indebtedness, general business conditions and such other factors
as our board of directors deems relevant.

                              OUR RECAPITALIZATION

     Immediately prior to the completion of this offering, the following
interdependent recapitalization transactions will occur:


     - the Next Level Communications L.P. $75.0 million note and accrued
       interest thereon payable to General Instrument will be contributed by
       General Instrument to Next Level Communications, Inc., a newly formed
       Delaware corporation and the issuer of the common stock being offered in
       this offering, in exchange for a number of shares of common stock equal
       to the aggregate amount owed under the note divided by the initial
       offering price (which would be 4,819,593 shares based upon $86.8 million
       which will be owed upon completion of the recapitalization and an assumed
       initial offering price of $18.00 per share); and


     - Next Level Communications L.P. and Next Level Communications, a wholly
       owned subsidiary of General Instrument and the limited partner of Next
       Level Communications L.P., each will be merged into Next Level
       Communications, Inc. As part of these mergers:

        - Spencer Trask, the general partner of the partnership, will receive
          5,863,329 shares of common stock for its 9.6% general partnership
          interest;


        - General Instrument will receive a number of shares of common stock,
          for Next Level Communications' 90.4% limited partnership and other
          interests under the partnership agreement, equal to 55,366,091 plus a
          number equal to $88.0 million divided by the initial offering price
          (which would be 4,888,889 shares based upon an assumed initial
          offering price of $18.00 per share) (General Instrument is receiving
          the additional number of shares of common stock to reflect the
          additional value, $88.0 million, that will be received by us upon
          exercise of the warrants, as described below, by affiliates of Spencer
          Trask. In accordance with the partnership agreement, Next Level
          Communications is entitled to receive the $88.0 million exercise price
          from affiliates of Spencer Trask. As a result of the mergers, such
          amount will be received by us should these warrants be exercised.
          Accordingly, General Instrument will receive $88.0 million of common
          stock because it would have received that amount under the partnership
          agreement);


        - options granted to employees of the partnership to purchase shares of
          Next Level Communications will become options to purchase a total of
          6,964,904 shares of common stock on a one for one basis; and

        - the option currently held by affiliates of Spencer Trask to purchase
          shares of the partnership's successor under the partnership agreement
          will become warrants to purchase from us 8,480,102 shares of common
          stock at an exercise price of $10.38 per share.


     As a result of these transactions and upon completion of this offering,
General Instrument will own 65,074,573 shares of common stock, constituting
64.9% of our outstanding common stock on a fully diluted basis. Spencer Trask
and its affiliates will own, including shares issuable upon exercise of
outstanding warrants, 14,343,431 shares of common stock in the aggregate,
constituting 14.3% of our outstanding common stock on a fully diluted basis. All
of the shares of common stock to be received by General Instrument pursuant to
our recapitalization will be held in a voting trust which will limit General
Instrument's voting power to 49% of our total voting power or a lower percentage
as General Instrument may later elect. Immediately upon the completion of its
pending merger with Motorola, General Instrument intends to terminate the voting
trust. For additional information about the voting trust, see "Certain
Relationships and Related Transactions -- Voting Trust Agreement."

                                 CAPITALIZATION

     The following table sets forth as of September 30, 1999:

     - the actual capitalization of Next Level Communications L.P.;

     - our pro forma capitalization assuming the completion of our
       recapitalization on September 30, 1999; and


     - our pro forma capitalization as adjusted to reflect the receipt of the
       estimated net proceeds from the sale of 8,500,000 shares of common stock
       in this offering at an assumed offering price of $18.00 per share, after
       deducting the estimated underwriting discounts and commissions and the
       estimated offering expenses:

</TABLE>


- -------------------------
(1) The information in the table above excludes:

    - options outstanding to purchase a total of 6,964,904 shares of common
      stock at a weighted average exercise price of $1.24 per share under our
      Amended and Restated 1997 Long-Term Incentive Plan,


    - options outstanding to purchase 5,393,854 shares of common stock at an
      exercise price of $11.00 per share under our 1999 Stock Plan, and


    - warrants held by affiliates of Spencer Trask to purchase 8,480,102 shares
      of common stock at an exercise price of $10.38 per share.


(2) The pro forma, as adjusted amount reflects the non-cash compensation expense
    associated with employee stock options to be recorded upon completion of
    this offering. The non-cash compensation expense related to these options,
    assuming no forfeitures, will be approximately $88.5 million, approximately
    $84.2 million of which will be expensed in the period in which this offering
    is completed. These charges are based upon an assumed initial offering price
    of $18.00 per share. These charges exclude any non-cash compensation expense
    which may result from the tandem stock option grant made in January 1997 to
    some of our employees. The tandem stock option grant permits these employees
    to exercise options for shares of either our or General Instrument's common
    stock. This non-cash compensation expense would be an additional $28.2
    million, based on an assumed initial offering price of $18.00 per share,
    assuming it becomes more likely that all tandem stock option holders will
    elect to exercise Next Level options. See note 9 of notes to the financial
    statements of Next Level Communications L.P. for a description of the tandem
    stock option grant.

                                    DILUTION


     The pro forma net tangible book value of our common stock as of September
30, 1999, assuming the completion of our recapitalization on that date, was
$39.9 million, or $0.56 per share. Pro forma net tangible book value per share
represents the amount of our pro forma stockholders' equity, less pro forma
intangible assets, divided by the number of shares of common stock outstanding
after giving pro forma effect to the recapitalization on September 30, 1999.



     Pro forma net tangible book value dilution per share represents the
difference between the amount per share paid by purchasers of shares of common
stock in this offering and the pro forma net tangible book value per share of
common stock immediately after completion of this offering. After giving effect
to the sale of 8,500,000 shares of common stock in this offering at an assumed
initial public offering price of $18.00 per share and the receipt of the
estimated net proceeds from this sale, after deducting estimated underwriting
discounts and commissions and estimated offering expenses payable by us, the pro
forma net tangible book value as of September 30, 1999 would have been $179.4
million, or $2.26 per share. This represents an immediate increase in net
tangible book value of $1.70 per share to existing stockholders and an immediate
dilution in net tangible book value of $15.74 per share to purchasers of common
stock in this offering. Investors participating in this offering will incur
immediate, substantial dilution. This is illustrated in the following table:

                            SELECTED FINANCIAL DATA

     The selected financial data set forth below should be read in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the historical financial statements and notes included in this
prospectus. The statement of operations data for the years ended December 31,
1996, 1997 and 1998 and the nine months ended September 30, 1999, and the
balance sheet data as of December 31, 1997 and 1998 and as of September 30,
1999, are derived from financial statements that have been audited by Deloitte &
Touche LLP, independent auditors, and are included in this prospectus. The
statement of operations data for the nine months ended September 30, 1998 are
derived from unaudited financial statements included in this prospectus and
include all adjustments (consisting of normal recurring items) that management
considers necessary for a fair presentation of the financial statements. The
statement of operations data for the periods from our inception on June 22, 1994
to December 31, 1994, from January 1, 1995 to August 31, 1995 and from September
1, 1995 to December 31, 1995 and the balance sheet data as of December 31, 1994,
1995 and 1996 are derived from unaudited financial statements not included in
this prospectus.

     The statement of operations data and balance sheet data for the periods
subsequent to August 31, 1995 reflect adjustments resulting from the application
of the purchase method of accounting in connection with our acquisition by
General Instrument in 1995. The financial information prior to August 31, 1995
is that of a predecessor company prior to its acquisition by General Instrument
and may not be comparable to the financial information for periods which began
subsequent to August 31, 1995. The results for the nine months ended September
30, 1999 are not necessarily indicative of the operating results to be expected
in the future.

                       PRO FORMA SELECTED FINANCIAL DATA


     The following unaudited pro forma statement of operations data for the year
ended December 31, 1998 and the nine months ended September 30, 1999, were
prepared to give effect to our recapitalization as if it occurred on January 1,
1998. The unaudited pro forma balance sheet data give effect to our
recapitalization as if it occurred on September 30, 1999. The unaudited pro
forma, as adjusted balance sheet data further give effect to our receipt of the
estimated net proceeds from the sale of 8,500,000 shares of common stock in this
offering at an assumed initial public offering price of $18.00 per share after
deducting underwriting discounts and commissions and estimated offering expenses
payable by us as if this offering had been completed on September 30, 1999. The
following pro forma and pro forma, as adjusted information does not purport to
represent what the operating results or financial position would have been or to
project the operating results or financial position for any future period or
date. The pro forma statement of operations data does not give effect to the
non-cash compensation expense associated with employee stock options to be
recorded upon completion of this offering. The non-cash compensation expense
related to these option grants, assuming no forfeitures, will be approximately
$88.5 million, approximately $84.2 million of which will be expensed in the
period in which this offering is completed. These charges are based upon an
assumed initial offering price of $18.00 per share. These charges exclude any
non-cash compensation expense which may result from the tandem stock option
grant made in January 1997 to some of our employees. This non-cash compensation
expense would be an additional $28.2 million, based on an assumed initial public
offering price of $18.00 per share, assuming it becomes more likely that all
tandem stock option holders will elect to exercise Next Level options. The pro
forma selected financial data should be read in conjunction with the
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the financial statements and notes thereto included in this
prospectus.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     You should read the following discussion and analysis along with selected
financial data, financial statements and the respective notes thereto included
elsewhere in this prospectus.

OVERVIEW

     We design and market broadband communications equipment that enables
telephone companies and other communications service providers to
cost-effectively deliver a full suite of voice, data and video services over the
existing copper wire telephone infrastructure. We commenced operations in July
1994 and recorded our first sale in September 1997. To date, we have sold our
products primarily to regional Bell operating companies through our direct sales
force. Since January 1998, we have operated through Next Level Communications
L.P., which was formed as the result of the transfer of all of the net assets,
management and workforce of a wholly owned subsidiary of General Instrument.
Immediately prior to the completion of this offering, the business and assets of
this partnership will be merged into Next Level Communications, Inc. as part of
our recapitalization.

     From inception through September 1997, our operating activities related
primarily to establishing a research and development organization, testing
prototype designs, designing circuits, commencing the staffing of marketing,
sales and field service and technical support organizations and establishing
manufacturing relationships. Since then, we have expanded our sales and
marketing and customer support activities. These activities include commencing
trials with our customers, expanding our customer base, developing customer
relationships, marketing our brand, hiring field service and customer support
personnel, developing new products and technologies and enhancing existing
products.

     Our revenue is primarily generated from sales of our equipment. A small
number of customers have accounted for a large part of our revenues to date, and
we expect this concentration to continue in the future. U S WEST accounted for
68% of total revenues for the year ended December 31, 1998 and 61% of total
revenues for the nine months ended September 30, 1999. Bell Atlantic accounted
for 20% of total revenues for the year ended December 31, 1998 and 14% of total
revenues for the nine months ended September 30, 1999. Our agreements with our
largest customers are cancelable by these customers on short notice and without
penalty, and do not obligate the customers to purchase any products. In
addition, our significant customer agreements generally contain fixed-price
provisions. As a result, our ability to generate a profit on these contracts
depends upon our ability to produce and market our products at costs lower than
these fixed prices.

     The timing of our revenue is difficult to predict because of the length and
variability of the sales cycle for our products. Customers view the purchase of
our products as a significant and strategic decision. As a result, customers
typically undertake significant evaluation, testing and trial of our products
before deploying them. This evaluation process frequently results in a lengthy
sales cycle, typically ranging from six months to more than a year. While our
customers are evaluating our products and before they place an order, if at all,
we may incur substantial sales and marketing expenses and expend significant
management efforts.

                                       26
<PAGE>   31

     Revenues. Our revenues consist primarily of sales of equipment and sales of
data communications software. We recognize equipment revenue upon shipment of
our products. Software revenue consists of sales to original equipment
manufacturers that supply communications software and hardware to distributors.
Software license revenue is recognized when a noncancelable license agreement
has been signed, delivery has occurred, the fees are fixed and determinable and
collection is probable. The portion of revenues from new software license
agreements which relate to our obligation to provide customer support are
deferred and recognized ratably over the maintenance period.

     Cost of revenues. Cost of equipment revenue includes direct material and
labor, depreciation and amortization expense on property and equipment, warranty
expenses, license fees and manufacturing and service overhead. Cost of software
revenue primarily includes the cost of the media the software is shipped on
(usually CDs) and documentation costs.

     Research and development. Research and development expense consists
principally of salaries and related personnel expenses, consultant fees,
prototype component expenses and development contracts related to the design,
development, testing and enhancement of our products. All research and
development costs are expensed as incurred.

     Selling, general and administrative. Selling, general and administrative
expense consists primarily of salaries and related expenses for personnel
engaged in direct marketing and field service support functions, executive,
accounting and administrative personnel, recruiting expenses, professional fees
and other general corporate expenses.


     Stock compensation expense. Substantially all of our employees have been
granted contingently exercisable stock options that will become options to
purchase our common stock upon our recapitalization. These options are
exercisable only in the event of our initial public offering or in a change of
control event such as a merger or acquisition. As a result, non-cash
compensation expense will be recognized upon the completion of this offering
based on the difference between the exercise price of these options and the
initial public offering price of our common stock. The non-cash compensation
expense related to these option grants, assuming no forfeitures, will be
approximately $88.5 million, approximately $84.2 million of which will be
expensed in the period in which this offering is completed. These charges are
based upon an assumed initial offering price of $18.00 per share. These charges
exclude any non-cash compensation expense which may result from the tandem stock
option grant made in January 1997 to some of our employees. The tandem stock
option grant permits these employees to exercise options for shares of either
our or General Instrument's common stock. This non-cash compensation expense
would be an additional $28.2 million based on an assumed initial offering price
of $18.00 per share, assuming it becomes more likely that all tandem stock
option holders will elect to exercise our options.


     Litigation. The litigation expense incurred in 1996 was attributable to a
judgment in connection with litigation involving DSC Communications and was paid
in 1997. The litigation expense incurred in 1998 was attributable to the cost of
the settlement of the litigation with BroadBand Technologies. For a more
detailed description of these litigation matters, see "Business -- Litigation."

     Acquisition. In September 1997, General Instrument acquired all of the
outstanding capital stock of Telenetworks for $7.0 million in cash, and
subsequently contributed the business to the Next Level partnership.
Approximately $6.9 million of the purchase price

                                       27
<PAGE>   32

was allocated to goodwill. As a result, we amortized approximately $1.0 million
of goodwill during 1998 and will continue to amortize the goodwill at a rate of
approximately $1.0 million per year for each of the next six years. In
conjunction with the granting of restricted common stock of General Instrument
to Telenetworks employees, which restrictions lapsed over a nine month period
that ended May 31, 1998, we recorded compensation expense of $3.9 million in
1998 and $3.1 million in 1997.

     The significant increase in equipment revenue from the second quarter of
1998 through the fourth quarter of 1998 was primarily attributable to the
purchases of our products by U S WEST in connection with its introduction of
video service in Phoenix, Arizona. U S WEST, however, did not deploy its video
service as rapidly as it had planned. As a result, in the first three quarters
of 1999, U S WEST slowed its purchases of our products for video applications
while it used its existing inventory, which accounted for the significant
decrease in our equipment revenue. The reduction in sales of our products for
video applications in the second and third quarters of 1999 was partially offset
by an increase in the sale of our products for voice applications to U S WEST
and new customers.

                                       28
<PAGE>   33

     The gross margins on our equipment revenue have been negative in six of our
last seven quarters primarily due to our relatively high fixed costs associated
with the manufacturing and testing of our products. At relatively low historical
volumes, we have not been able to cover our fixed costs and, as a result, our
unit costs are high. We expect to achieve margin improvements in future
quarters, based on higher sales volumes, cost reductions and increased demand
for higher margin products.

     The increase in research and development expense in the fourth quarter of
1998 reflects the higher level of spending in the second half of 1998 due to
increased product development costs in connection with increased demand for our
products. In addition, there were higher engineering costs incurred in
connection with the U S WEST deployment. We view research and development as
critical to attaining our goals and thus we expect research and development
expense to increase as we continue to enhance existing products and begin new
product initiatives.

     Selling, general and administrative expense in the first two quarters of
1998 included the amortization of the compensation expense incurred in
connection with the acquisition of Telenetworks and legal fees incurred in
connection with the settlement of the BroadBand Technologies litigation.
Beginning in the fourth quarter of 1998, we expanded our customer focus to local
and independent telephone companies and thus we have been adding personnel in
our sales and marketing group. As a result, selling, general and administrative
expense has continued to increase and we expect this trend to continue.

     The litigation expense incurred in the first quarter of 1998 reflects the
cost of the settlement of the litigation with BroadBand Technologies.

NINE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998

     Revenues. Total revenues increased to $32.4 million for the nine months
ended September 30, 1999 from $21.2 million for the nine months ended September
30, 1998. This increase was primarily due to an increase in equipment sales.

     Equipment revenue increased to $29.8 million for the nine months ended
September 30, 1999, from $17.7 million for the nine months ended September 30,
1998. Sales to two regional Bell operating companies, U S WEST and Bell
Atlantic, comprise substantially all of the equipment revenue to date. U S WEST
accounted for $19.9 million and Bell Atlantic accounted for $4.7 million of
equipment revenue for the nine months ended September 30, 1999. Sales of
equipment to the local and independent telephone markets were $4.8 million for
the nine months ended September 30, 1999, with most of those sales occurring in
the third quarter. The growth in equipment revenue in future periods will depend
upon whether and how quickly our existing customers roll out broadband services
in their coverage areas and whether and how quickly we obtain new customers.

     Data communications software revenue decreased to $2.6 million for the nine
months ended September 30, 1999 from $3.5 million for the nine months ended
September 30, 1998 due primarily to a shift in demand from 1999 into 1998. We
expect demand for our software to remain relatively flat in the near term
because the market for these products is mature, and we are not making any
significant investment in new products for that market. As a result, we expect
our level of software revenue to remain relatively stable.

     Cost of Revenues. Total cost of revenues increased to $30.0 million for the
nine months ended September 30, 1999 from $21.8 million for the nine months
ended September 30, 1998. The increase in the cost of revenues was attributable
to an increase in

                                       29
<PAGE>   34

equipment volume and consisted primarily of materials and costs associated with
increasing production at our contract manufacturers.

     For the nine months ended September 30, 1999, our gross profit (loss) on
equipment was $0.1 million and for the nine months ended September 30, 1998, our
gross profit (loss) on equipment was $(3.8 million). The improvement in gross
profit (loss) was primarily the result of higher unit volumes, leading to
greater efficiencies, including lower fixed costs per unit. We plan to achieve
gross margin improvements as we increase sales of our higher margin products,
increase volume, and continue implementing cost reductions. Our software gross
margins in each period were comparable.

     Research and development. Research and development expenses increased to
$35.9 million for the nine months ended September 30, 1999 from $32.5 million
for the nine months ended September, 1998. The increase was primarily due to an
increase in research and development personnel. We believe that continued
investment in research and development is critical to attaining our strategic
product development and cost reduction objectives and, as a result, expect these
expenses to increase in absolute dollars.

     Selling, general and administrative. Selling, general and administrative
expenses increased to $22.2 million for the nine months ended September 30, 1999
from $19.9 million for the nine months ended September 30, 1998. Approximately
$3.9 million of compensation expense relating to the Telenetworks acquisition is
included in the amount for 1998. There was no Telenetworks compensation expense
during the nine months ended September 30, 1999. This decrease in compensation
expense was offset by a substantial increase in selling, general and
administrative expenses in the 1999 period due to the increase in scale of our
operations including additional personnel in the sales and marketing
organizations, promotional expenses and other administrative expenses. We expect
selling, general and administrative expenses to increase as we continue to add
personnel and incur additional costs as we increase the scale of our operations.

     Litigation. Litigation expenses of $5.0 million for the nine months ended
September 30, 1998 related to the settlement cost of litigation with BroadBand
Technologies. For a detailed discussion of this litigation matter, see
"Business -- Litigation."

     Other income (expense), net. Other income (expense) consists primarily of
interest income. The decrease in interest income to $0.9 million for the nine
months ended September 30, 1999 from $2.1 million for the nine months ended
September 30, 1998 was due to a reduced level of cash and cash equivalents
during the 1999 period.

     Interest expense. Interest expense increased to $5.2 million for the nine
months ended September 30, 1999, from $4.4 million for the nine months ended
September 30, 1998. The interest expense in these periods is primarily
attributable to interest on a $75.0 million note and accrued interest thereon
payable to General Instrument that General Instrument will contribute to us in
exchange for shares of our common stock immediately prior to completion of this
offering as part of our recapitalization.

YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996

     Revenues. Total revenues increased to $43.8 million in 1998 from $8.3
million in 1997. We recorded our first sale in September 1997 and, therefore,
the operating results for 1997 reflect only four months of revenues. We did not
ship product in 1996 and, accordingly, did not recognize any revenues in 1996.

                                       30
<PAGE>   35

     Total revenues for the year ended December 31, 1998 included $39.2 million
of equipment sales, compared to $6.0 million of equipment sales for the year
ended December 31, 1997. U S WEST accounted for $29.9 million and Bell Atlantic
accounted for $8.6 million of equipment revenue for the year ended December 31,
1998. U S WEST accounted for $1.4 million and NYNEX (now part of Bell Atlantic)
accounted for $4.6 million of equipment revenue for the year ended December 31,
1997. We expect to continue to derive substantially all of our revenues from
sales of equipment to the regional Bell operating companies and local and
independent telephone companies for the foreseeable future.

     In 1998 and 1997, software revenue consisted of sales to original equipment
manufacturers that supply communications software and hardware to distributors.
For the year ended December 31, 1998, software revenue was $4.6 million and for
the year ended December 31, 1997, software revenue was $2.3 million. Software
revenue for 1997 was comprised of four months of revenue from Telenetworks.

     Cost of Revenues. Total cost of revenues increased to $43.4 million for the
year ended December 31, 1998 from $11.3 million for the year ended December 31,
1997 and related substantially to cost of equipment. The increase in cost of
revenues in 1998 and 1997 was primarily the result of materials cost and costs
associated with increasing production at our contract manufacturers as a result
of increased equipment sales volume.

     Research and development. Research and development expenses increased to
$47.1 million for the year ended December 31, 1998, from $37.1 million for the
year ended December 31, 1997 and $17.1 million for the year ended December 31,
1996. The increase in 1998 was primarily the result of increased personnel,
increased component purchases and spending on third-party testing, development
of the Residential Gateway product, and the completion of our products for voice
applications. The increase in 1997 was primarily due to increased personnel in
research and development, the corresponding procurement of components and test
fixtures, increased system testing and the commencement of development of video
products.

     Selling, general and administrative. Selling, general and administrative
expenses were $26.2 million for the year ended December 31, 1998, compared to
$26.4 million for the year ended December 31, 1997 and $15.9 million for the
year ended December 31, 1996. The decrease in 1998 reflects the reduction in
legal expenses associated with the DSC Communications litigation that was
partially offset by costs associated with the increased selling efforts
resulting from the commencement of the commercial sales of our products in
September 1997, as well as expansion into new markets. These costs include
recruiting, travel, tradeshows, print advertising, public relations and other
promotional expenses. The increase in 1997 was primarily due to higher costs
associated with increased personnel in the sales and marketing organizations as
well as higher legal expenses due to the litigation with DSC Communications.

     Litigation. Litigation expense of $5.0 million for the year ended December
31, 1998 related to the settlement cost of litigation with BroadBand
Technologies. In 1996, a final judgment was entered in favor of DSC
Communications and DSC Technologies, and an expense for the expected final award
of $141.0 million was recorded in 1996. The $141.0 million judgment was paid in
1997. For a detailed discussion of these litigation matters, see
"Business -- Litigation."

                                       31
<PAGE>   36

     Other income, net. Other income of $2.2 million for the year ended December
31, 1998 was due to interest income on cash and cash equivalents. Other income,
net was not significant in 1997 or 1996.

     Interest expense. Interest expense was $6.0 million in 1998 due almost
entirely to interest on the $75.0 million note and accrued interest thereon
payable to General Instrument. There was no interest expense in 1997 or 1996.

LIQUIDITY AND CAPITAL RESOURCES

     We have financed our operations primarily through cash contributions and
borrowings from General Instrument. General Instrument will not provide us
additional funds after this offering.

     Net cash used in operating activities was $44.4 million for the nine months
ended September 30, 1999 and $63.0 million for the nine months ended September
30, 1998. In each case, the use of cash in operating activities was primarily
due to our net losses, partially offset by an increase of $12.7 million in
deferred revenues in the 1999 period. Net cash used in operating activities of
$66.6 million in 1998 was primarily due to a net loss of $81.7 million,
partially offset by non-cash depreciation charges. Net cash used in operating
activities of $208.5 million in 1997 was due to a net loss of $66.4 million,
payments of litigation expenses of $141.0 million and an increase in
inventories. Net cash used in operating activities of $33.0 million in 1996 was
primarily due to a net loss of $173.9 million offset by $141.0 million of
accrued litigation expenses.

     Net cash used in investing activities of $6.1 million for the nine months
ended September 30, 1999, $6.9 million for the nine months ended September 30,
1998, $9.3 million for the year ended December 31, 1998, $9.8 million for the
year ended December 31, 1997 and $9.3 million for the year ended December 31,
1996 was primarily attributable to capital expenditures to support our
engineering and testing activities. As we increase the scope of our operations,
we expect that our capital expenditures will increase.

     Net cash provided by financing activities of $34.0 million in the nine
months ended September 30, 1999 and $89.0 million in the nine months ended
September 30, 1998 consisted of capital contributions from the partners and a
$75.0 million loan from General Instrument in the 1998 period. Net cash provided
by financing activities of $104.6 million for the year ended December 31, 1998
consisted of a $75.0 million loan from General Instrument, a $19.6 million
capital contribution from General Instrument and a $10.0 million capital
contribution from the general partner. Net cash provided by financing activities
of $218.7 million for the year ended December 31, 1997 consisted of
contributions from General Instrument. Net cash provided by financing activities
of $41.7 million for the year ended December 31, 1996 was due to borrowings from
General Instrument.

     At September 30, 1999, we had $12.5 million of cash and cash equivalents
and $17.4 million of working capital. However, we anticipate that we will
increase our capital expenditures and lease commitments consistent with
anticipated growth in operations, infrastructure and personnel. We may establish
sales offices and lease additional space, which will require us to commit to
additional lease obligations, purchase equipment and install leasehold
improvements.

     We have commitments with suppliers to purchase a total of approximately
$24.0 million of components through 2002.

                                       32
<PAGE>   37


     In January 1998, we borrowed $75.0 million from General Instrument pursuant
to an 8% note due in 2005. Deferred interest payments bear interest at 10%. At
September 30, 1999, we owed General Instrument $86.0 million under the note,
including accrued interest of $11.0 million. This note, including accrued
interest thereon, will be contributed to us by General Instrument in exchange
for approximately 4,819,593 shares of common stock immediately prior to the
completion of this offering as part of our recapitalization. This number of
shares is based upon $86.8 million owed at completion of the recapitalization
and an assumed initial offering price of $18.00 per share. As a result of the
recapitalization, we do not expect to currently have material debt service
requirements.


     We expect to experience significant growth in our operating expenses for
the foreseeable future. As a result, we anticipate that operating expenses, as
well as planned capital expenditures, will constitute a material use of our cash
resources. In addition, we may use cash resources to fund acquisitions or
investments in complementary businesses, technologies or product lines. Our long
term operating and capital lease obligations are generally less than $3.0
million per year and are described in notes 11 and 12 to the financial
statements of Next Level Communications L.P. Other than capital lease
commitments, we have no material commitments for capital expenditures. As we
increase the scope of our operations, we expect that our capital expenditures
will increase. We believe that our cash on hand and the net proceeds from the
sale of the common stock in this offering will be sufficient to meet our working
capital and capital expenditure requirements for at least the next 12 months.
However, it may still be necessary to obtain additional equity or debt financing
either during or after the next 12 months if we are not able to generate
sufficient cash from operating activities to meet our capital expenditure and
working capital needs. In the event additional financing is required, we may not
be able to raise it on acceptable terms, or at all.

YEAR 2000

     The year 2000 issue has arisen as a result of computer programs being
written using two digits rather that four to define the applicable year. Some
information technology systems and their associated software, and other
equipment that uses programmable logic chips to control aspects of their
operation, commonly referred to as embedded chip equipment, may recognize "00"
as a year other than the year 2000. Some information technology systems and
embedded chip equipment used by us and by third parties who do business with us
contain two-digit programming to define a year. The year 2000 issue could
result, for us and for others, in system failures or miscalculations causing
disruptions of operations, including, among other things, a temporary inability
to process transactions or to engage in other normal business activities. We
believe our products are year 2000 compliant.

     Readiness for Year 2000

     We are addressing year 2000 issues relating to:

     - embedded chip equipment sold by us;

     - information technology systems and embedded chip equipment used by us;

     - third parties who do business with us that may not be prepared for the
       year 2000; and

     - contingency planning.

     We use a variety of information technology systems, internally developed
and third-party provided software and embedded chip equipment in our products.
For these

                                       33
<PAGE>   38

information technology systems, software and embedded chip equipment, we have
divided our year 2000 efforts into four phases:

     (1) identification and inventorying of information technology systems and
         embedded chip equipment with potential year 2000 problems;

     (2) evaluation of scope of year 2000 issues for, and assigning priorities
         to, each item based on its importance to our operations;

     (3) remediation of year 2000 issues in accordance with assigned priorities,
         by correction, upgrade, replacement or retirement; and

     (4) testing for and validation of year 2000 compliance on an application
         and enterprise wide basis.

     We have categorized as "mission critical" those information technology
systems and embedded chip equipment whose failure would cause cessation of
operations or significant detrimental financial impact on us. Phase (1) and (2)
are complete across all "mission critical" business functions and locations. All
mission critical information technology systems and embedded chip equipment are
currently in phase (3) or (4) and we expect these phases to be completed by
November 1999. We will conduct a comprehensive program of integration testing of
internal systems to ensure that all systems still work together properly and
without year 2000 problems.

     Our operations are also dependent on the year 2000 readiness of third
parties, including our contract manufacturers, that we do business with. In
particular, we are in the process of configuring our information technology
systems to interact with commercial electronic transaction processing systems of
our customers. In addition, we are dependent on third-party suppliers of
infrastructure elements such as telecommunications services, electric power,
water and banking facilities.

     We have identified and initiated formal communications with key third
parties, including our contract manufacturers, to determine the extent to which
we will be vulnerable to such parties' failure to resolve their own year 2000
issues. To the extent that we are not able to test the technology provided by
third-party vendors, we are seeking assurances from these vendors that their
systems are year 2000 compliant. As a follow-up, we plan to determine whether
our customers and suppliers are taking appropriate steps to achieve year 2000
readiness and ensure continued functioning in accordance with our business
needs. We are assessing our risks with respect to failure by third parities to
be year 2000 compliant and intend to seek to mitigate those risks. We are also
developing contingency plans, discussed below, to address issues related to
third parties we determine are not making sufficient progress toward becoming
year 2000 compliant.

     Costs

     Due to the lack of older systems subject to remediation, we expect that our
overall cost of achieving year 2000 compliance will not be material. The total
cost through September 30, 1999 of our year 2000 activities was approximately
$100,000 and the cost of our remaining year 2000 activities is estimated to be
approximately $64,000. Our estimate of the cost of achieving year 2000
compliance and the date by which year 2000 compliance will be achieved are based
on our best estimates, which were derived using numerous assumptions about
future events including the continued availability of certain resources, third
party modification plans and other factors. However, there can be no assurance
that

                                       34
<PAGE>   39

these estimates will be achieved and actual results could differ materially from
these estimates. Specific facts that might cause such material differences
include the availability and cost of personnel trained in year 2000 remediation
work, the ability to locate and correct all relevant computer codes, the success
achieved by our customers and suppliers in reaching year 2000 readiness, the
timely availability of necessary replacement items and similar uncertainties.

     Some commentators have predicted significant litigation regarding year 2000
compliance issues, and we are aware of these lawsuits against other vendors.
Because of the unprecedented nature of this litigation, it is uncertain whether
or to what extent we may be affected by it. If we are subject to claims by our
customers asserting liability, including liability for breach of warranties
related to the failure of our products to function properly, the cost of this
litigation and any settlement or judgment costs could be material.

     Contingency Plans

     We presently believe that the most likely worst-case year 2000 scenarios
would relate to the possible failure in one or more geographic regions of
third-party systems over which we have no control and for which we have no ready
substitute, such as, but not limited to, power and telecommunications services.
We have in place a business resumption plan that addresses recovery from various
kinds of disasters, including recovery from significant interruptions to data
flows and distribution capabilities. We are using that plan as a starting point
for developing specific year 2000 contingency plans, which will emphasize
locating alternate sources of supply, methods of distribution and ways of
processing information.

     We anticipate this contingency planning will prepare our business for
disruptions but will not protect us fully from commercial impact. We are
currently initiating the following efforts:

     - Prioritizing all hardware, software and services across the enterprise.

     - Developing contingency plans for top priority items.

There can be no assurance that we will be able to complete our contingency
planning before January 1, 2000.

RECENTLY ISSUED ACCOUNTING STANDARD

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This statement requires companies to record derivatives
on the balance sheet as assets or liabilities, measured at fair value. Gains or
losses resulting from changes in the values of those derivatives would be
accounted for depending on the use of the derivative and whether it qualifies
for hedge accounting. Statement of Financial Accounting Standards No. 133, as
amended by Statement of Financial Accounting Standards No. 137, will be
effective for our fiscal year ending December 31, 2001. Management is currently
evaluating what impact, if any, Statement of Financial Accounting Standards No.
133 may have on our financial statements.

                                    BUSINESS

OVERVIEW

     We design and market broadband communications equipment that enables
telephone companies and other communications service providers to
cost-effectively deliver a full suite of voice, data and video services over the
existing copper telephone wire infrastructure. Service providers who deploy our
equipment can either offer voice, data and video services in a single product
offering or offer each service separately depending on subscriber demand and the
service provider's objectives. We believe that by installing our equipment,
telephone companies and other emerging communications service providers will be
able to capitalize on, and compete effectively in, the emerging market for
integrated voice, data and video services. Our products consist of equipment
located at the telephone company's central office, in the field and at the
subscriber's home or business.

     We commenced operations in July 1994 and recorded our first sale in
September 1997. From inception through September 30, 1999, approximately 82% of
our revenues were from sales to U S WEST and Bell Atlantic. We incurred a net
loss of $59.9 million for the nine months ended September 30, 1999 and $81.7
million for the year ended December 31, 1998.

INDUSTRY BACKGROUND

Increasing Demand for Voice, Data and Video Services

     In recent years, the volume of voice, data and video traffic across
communications networks has grown dramatically due to:

     - the increasing use of the Internet as an essential communications and
       transaction medium;

     - the growth in remote access by telecommuters; and

     - the increasingly diverse distribution sources for high quality digital
       video.

According to International Data Corporation, the number of Internet users
worldwide reached approximately 142 million in 1998 and is forecasted to grow to
approximately 502 million by the end of 2003, while the number of homes
worldwide with remote access connections is expected to increase from 81 million
in 1999 to 157 million in 2003. In addition, in a June 1999 report, Paul Kagan
Associates estimates that the number of U.S. cable television subscribers is
expected to increase from 67 million in 1999 to 71 million in 2003, while the
number of digital set-top box units is expected to increase from 5 million in
1999 to 29 million in 2003. The growth in traffic and increasing demand for
high-speed data and video services has forced communications companies to find
ways to deliver these services more cost effectively.

Increased Competition for Communications Services

     The increasing demand for voice, data and video services combined with
deregulation of the communications industry has created new opportunities and
challenges for communications service providers. As service providers seek to
capitalize on these opportunities to deliver a broader set of services, local
connections to residential and business subscribers have become an increasingly
valuable asset. The two most prevalent

                                       36
<PAGE>   41

types of local connections in North America are copper wire and cable. Service
providers that use copper wire are facing increasing competitive pressures from
providers using cable. Recently, certain service providers have announced plans
to provide voice, data and video services over cable. For example, AT&T recently
acquired TCI and entered into an agreement to acquire Media One. AT&T then
announced plans to accelerate the upgrade of TCI's cable systems to offer
packaged services. AT&T plans to provide not only data and video but also voice
over its own cable systems and over other cable systems through partnerships
with other cable service providers. These packaged services will give
residential and business subscribers the ability to purchase all communications
services from a single provider. This could provide more favorable pricing and a
single point of contact for bill payment and customer service. If these cable
providers can successfully package and market these services, they will compete
directly with the services offered by telephone companies.

     Although telephone companies have the opportunity to sell packaged
broadband services to their large number of voice customers, they have been
constrained by limitations in their existing networks. In particular, the
connection between the subscriber and the telephone company's central office,
referred to as the "last mile," is the slowest portion of the communications
infrastructure and often acts as a bottleneck in the delivery of high-speed data
and video traffic. As overall demand for services continues to rise, these
limitations are becoming increasingly apparent and are resulting in lost revenue
for service providers and inadequate network service for their customers.

Evolution of the "Last Mile"

     Historically, the telephone company infrastructure consisted primarily of
twisted pairs of copper wires that spanned the distance from their customers'
homes or businesses to a central office where they connected to a voice switch.
This infrastructure was originally designed to transmit analog voice traffic.
Over the last several years, telephone companies have installed equipment in
some locations between the telephone company's central office and clusters of
end-users in an effort to make their networks more cost efficient. This
equipment has enabled telephone companies to convert their analog traffic into
more efficient digital data streams and extend higher capacity fiber optic cable
further into their networks. Although these systems have often resulted in more
cost efficient voice communications, they are generally not designed to deliver
data and video services to individuals and businesses.

     To take advantage of their existing copper wire infrastructure and respond
to the increased demand for data services, some telephone companies have
recently begun to create data networks separate from their voice networks by
connecting additional equipment to their central office equipment. To date, most
of this equipment has been deployed to provide Internet access to individuals
and businesses. Although this equipment typically provides higher speed than the
earlier systems, it is generally not designed to provide high quality video
services. Thus, telephone companies seeking to offer a variety of services to
their customers often must do so from multiple and distinct networks. This is
because each individual system is typically unable to offer voice, data and
video services in a single package.

                                       37
<PAGE>   42

     Traditional telephone companies are seeking solutions that enable them to
continue to compete in their existing market for voice services as well as in
the emerging data and video markets because of:

     - the increasing demand for high-speed data and video services;

     - the greater competition among service providers; and

     - the limitations of existing copper wire networks.

To match their capital expenditures to subscriber demand for services, many
telephone companies are seeking flexible solutions with which they can add new
services over time. Despite the desire by many telephone companies to simplify
and reduce costs, companies seeking to deploy multiple services have generally
needed to deploy separate networks from multiple vendors. This strategy is
costly and increases the complexity of installation, operation and maintenance.

OUR SOLUTION

     We design and market broadband communications equipment that enables
telephone companies and other communications service providers to
cost-effectively deliver a full suite of voice, data and video services over the
existing copper telephone wire infrastructure. Our equipment is designed to
provide the following key competitive advantages and benefits:

     Flexible, Integrated Products. Our products are designed with the
flexibility to allow our customers to deliver voice, data and video services in
a single packaged offering or to offer them individually. This flexibility
allows telephone companies to immediately serve the varying needs of their
diverse end-user base, including residential, corporate and telecommuter
customers. As a result, telephone companies can generate significant incremental
revenue from their existing networks by using our system. By offering the
flexibility inherent in an integrated system, our products enable telephone
companies to effectively time their network equipment expenditures and rapidly
introduce new services as demand warrants.

     Cost Effective Product Deployment. Our product design reduces the cost and
complexity often associated with deploying multiple services to end-users.
Because telephone companies often use separate equipment for each communications
service, they require multiple equipment purchases, installations, training
procedures, maintenance procedures and network management packages. In contrast,
our products deliver all services from a single system. By integrating many
traditionally separate functions, our products allow telephone companies to
incrementally add services by simply installing new modules into our existing
equipment, rather than purchasing entirely new infrastructure equipment.
Additionally, our products installed in the house or office deliver video and
data services from a single networked set-top box, thus eliminating the need for
set-top boxes or modems for different services or separately located TVs and
PCs. We believe our products provide cost savings, reduce trouble calls and ease
installation compared to other equipment that often consists of separate
systems, each of which corresponds to one service and which may not operate
effectively together.

     Complete Solution For Delivery of Voice, Data and Video. By supplying
equipment for the telephone company central office, the field and the
subscriber's home or office, we offer a single integrated system for the
delivery of voice, data and video services. With our

                                       38
<PAGE>   43

products, telephone companies initially deploying voice service can subsequently
activate data and/or video service with a simple addition and installation of
equipment at the subscriber's home or office. We believe the flexibility found
in our products cannot currently be accomplished by attempting to integrate
multiple systems from multiple vendors.

     Reliable and Compatible Technology. Because our products provide multiple
services, including voice, they are engineered to comply with rigorous industry
standards for reliability and safety. Our products are also designed to operate
with existing telephone company switches and billing systems, thereby minimizing
the cost of using our products.

     Security. We believe that our products produce greater security compared to
cable systems that are based on shared network design in which data is broadcast
to all users simultaneously. Security has always been important to individuals
and businesses in voice transmission and is becoming increasingly important as
e-commerce applications and video-on-demand services become more prevalent.

OUR STRATEGY

     Our objective is to be the leading supplier of products that enable
telephone companies and other emerging communication service providers to
cost-effectively deliver a full suite of voice, data and video services over the
existing copper telephone wire infrastructure. Key elements of this strategy
include the following:

     Increase Penetration of Existing Customer Base. As the needs of our
customers evolve, we intend to:

     - use our success achieved with key customers to increase sales;

     - extend our product offerings; and

     - maintain a high level of customer support.

     To date, telephone companies have deployed our products to offer a subset
of services in a limited number of locations. We believe there is a significant
opportunity to increase our sales as customers expand to more locations within
their regions and/or as they offer more services at each location. In addition,
we believe our existing agreements with some of our customers provide us with a
competitive advantage as a preferred vendor if and when these customers develop
their next generation of broadband networks. We intend to leverage this
advantage to be the supplier of complete communications solutions to our
customers. For example, we recently expanded our relationship with U S WEST. In
the past, our relationship with U S WEST was confined to providing equipment to
offer voice, data and video services solely in the Phoenix, Arizona service
area. We recently entered into a new agreement with U S WEST to provide our
products for voice applications in six of the 14 states in U S WEST's territory.

     Expand Customer Base to Other Communications Providers. We believe our
products' price and performance advantages offer communications service
providers using copper telephone wires a cost-effective solution to upgrade
their networks to offer voice, data and video services. Consequently, we have
recently aggressively expanded our product marketing beyond regional Bell
operating companies to other communications providers using copper wire
infrastructure, including local and independent telephone companies. These
companies have often been quick to embrace and adopt new technologies. Although

                                       39
<PAGE>   44

many international telephone markets are still in the early stages of deploying
high-speed data and video services, we intend to market our products to targeted
international telephone companies. Accordingly, we are expanding our sales force
to capitalize on these new opportunities.

     Provide Competitive Advantages to our Customers. Our system offers
flexibility to allow delivery of voice, data, and video traffic either in a
packaged or separate product offerings in any combination chosen by a service
provider. By supporting incremental deployment of services, rather than upfront
network buildouts, we believe our system provides telephone companies a more
effective means of managing system development and expansion by enabling these
companies to better match their capital expenditures to subscriber demand for
services. Additionally, our products offer a complete solution including our
set-top box, the Residential Gateway, at the subscriber's home or business. Our
set top box provides telephone companies and their customers with an integrated
solution that is more cost effective than deploying the separate modems or
set-tops often otherwise necessary to provide multiple services. As demand for
high-speed data and video services increases, we intend to continue focusing on
providing our customers products which allow them to cost-effectively deliver
multiple services.

     Maintain and Extend Technology Leadership. We believe that we are currently
a technology leader in engineering integrated voice, data and video solutions.
We intend to maintain and extend our technology leadership through continued
research and development of integrated systems for voice, data and video
transmission over a variety of fiber, copper, satellite and various mixes of
these and other networks. Accordingly, we plan several new products and
enhancements, including integration of our customer premises equipment with
Direct Broadcast Satellite and other types of networks to deliver increased cost
savings, additional functionality and more flexible delivery capability to the
telephone companies and their customers.

     Outsource Manufacturing. Our manufacturing strategy focuses on the use of
one or more contract manufacturers for the assembling, testing, packaging,
warehousing and shipping of products. Currently, we use two large contract
manufacturers: SCI Systems and CMC Industries. Using contract manufacturers
allows us to:

     - achieve economies of scale in purchasing;

     - respond rapidly to large customer orders;

     - reduce costly investment in manufacturing capital; and

     - reduce inventory warehousing.

                                       40

PRODUCTS

     Our products include equipment located at a telephone company's central
office, in the field and at a subscriber's home or business. Key elements of our
solution, which are described below, are the Broadband Digital Terminal,
Universal Service Access Multiplexer, Broadband Network Unit, Residential
Gateway, ETHERset, N(3) NIC, N(3) View-1 Element Management System and N(3)
View-2 Service Manager. An application of our products is demonstrated in the
following diagram:

</TABLE>

     Broadband Digital Terminal. The Broadband Digital Terminal is the central
element of our product suite, providing centralized access to both broadband and
narrowband networks and related voice, data and video services. The Broadband
Digital Terminal is typically located in a telephone company's central office,
or at a remote cabinet, building basement or hut where it connects with central
office equipment including voice and data switches and billing systems. On the
subscriber side, the Broadband Digital Terminal provides high-speed connections
to remote Universal Service Access Multiplexers or Broadband Network Units that
can support up to a maximum of 2,048 data or video subscribers, up to a maximum
of 6,144 telephone subscribers or combinations thereof. The Broadband Digital
Terminal has the capacity for broadband applications such as video-on-demand and
high definition television. Also, because the Broadband Digital Terminal
supports different remote terminals, changes to network layouts or transmission
media (copper or fiber) do not require different Broadband Digital Terminals.

     Universal Service Access Multiplexer. The Universal Service Access
Multiplexer is designed to use existing copper wire to connect to a customer's
home or office and can be connected with fiber optic cable to the Broadband
Digital Terminal. Each Universal
                                       41
<PAGE>   46

Service Access Multiplexer can support up to 32 video and/or data subscribers or
up to 96 voice subscribers. By using modular components, a single Universal
Service Access Multiplexer enables multiple voice, data and video services. The
Universal Service Access Multiplexer can be deployed in the telephone company's
central office or remotely. Because the Universal Service Access Multiplexer is
flexible in terms of where it can be located in the network, as well as the
services it can support, its use can reduce both the costs and the complexity of
deploying new high-speed data and video services.

     Broadband Network Unit. The Broadband Network Unit is used with
installations where fiber optic cable is deployed up to a location relatively
close to the customer's home or office. The Broadband Network Unit supports
voice, data and video services, and can be mounted on a telephone pole, a
pedestal or a wall. The Broadband Network Unit provides voice, high-speed data
and video service for clusters of up to 24 video and/or data and up to 36 voice
subscribers. Our Broadband Network Unit is particularly suited to situations
where a new network is being built, or where existing copper wire is being
upgraded by the installation of fiber optic cable as the transmission medium for
residences or larger apartment buildings or offices. The advanced design and
environmentally secure housing of the Broadband Network Unit results in low
in-field trouble calls.

     Residential Gateway. Our Residential Gateway product is a single set-top
box that delivers integrated data and video services. One Residential Gateway
enables multiple televisions and personal computers to be served from the same
access line into the customer's home or office. Traditionally, the high cost of
customer home or office equipment for broadband services has been a limiting
factor in the deployment of broadband services to multiple televisions or
personal computers. Historically, a customer would have to obtain multiple
modems or set-top boxes to support services to multiple televisions or personal
computers. In contrast, our Residential Gateway simultaneously provides three
independent high quality video streams that can be distributed throughout a home
or office using standard coaxial cable. The primary video stream is also
available in common video and stereo surround sound formats. The Residential
Gateway also supports enhanced telephone services, such as an indicator on the
television that a message is waiting on the customer's answering machine or
service as well as on-screen caller ID. The data port in our Residential Gateway
supports high-speed connectivity to the Internet or remote work-at-home access.

     ETHERset. Our ETHERset is a data-only, desktop device that provides a
powerful, low-cost solution for delivering high-speed Internet or data services
to subscribers in residences, small businesses, branch offices and the like.
Individual or multiple personal computers can be connected to a single ETHERset.

     N(3) NIC. The N(3) NIC is a card, designed to fit into a personal computer,
that provides the same functionality as our ETHERset.

     Element Management Systems. Our products can be managed remotely by our
N(3) View-1 Element Management System and our N(3) View-2 Service Manager. The
View-1 Element Management System enables service providers to manage our
equipment and their other systems and products. The View-2 Service Manager
enables service providers to manage delivery of voice, data and video services
to their customers.

CUSTOMERS

     We market and sell our products through our direct sales force to service
providers that seek to deliver the next generation of broadband services. From
inception through September 30, 1999, approximately 82% of our sales were to U S
WEST and Bell Atlantic. We recently initiated customer relationships in the
local, independent and international telephone company markets. As of September
30, 1999, we had 12 customers who have purchased at least $100,000 of our
products. The following describes our relationship with some of these customers.

     U S WEST: In August 1997, we entered into an agreement with U S WEST
through which U S WEST may purchase, without obligation to do so, up to 450,000
Residential Gateways and associated central office and field equipment, in eight
of the 14 states in which U S WEST currently operates over a five year period.
We recorded our first sale to U S WEST in September 1997 for deployment of video
and data service to U S WEST's customers in Phoenix, Arizona. In October 1998, U
S WEST selected our product to provide voice applications in six of the 14
states that U S WEST serves. Sales to U S WEST represented 68% of our revenues
in fiscal 1998 and 61% in the nine months ended September 30, 1999.

     Bell Atlantic: In October 1996, we entered into an agreement with NYNEX
(now part of Bell Atlantic) through which Bell Atlantic may purchase, without
obligation to do so, equipment for up to 5,000,000 lines, consisting of
Broadband Network Units and associated equipment, throughout its service area
over a fifteen-year period. The primary application for these products is
rehabilitation of Bell Atlantic's existing network equipment from copper to
fiber. We recorded our first sale to Bell Atlantic in September 1997 for
deployment in the Boston area. Bell Atlantic is currently using our system to
serve customers in the New York City and Boston areas. Sales to Bell Atlantic
represented 20% of our revenues in fiscal 1998 and 14% in the nine months ended
September 30, 1999.

     GTE: In April 1998, we entered into an agreement with GTE through which GTE
may purchase, without obligation to do so, our Residential Gateways and
associated central office and field equipment. Through a development agreement,
GTE has commenced a trial deployment of our products for video applications to
customers in the Clearwater, Florida area.

     Hutchinson Telephone: In February 1999, we received our first order from an
independent telephone company, Hutchinson Telephone, for deployment of our
equipment. Hutchinson has announced that it intends to deploy our Universal
Services Access Multiplexers and Broadband Digital Terminals for voice,
high-speed data and other services.

     Paul Bunyan Rural Telephone: In April 1999, Paul Bunyan Rural Telephone, an
independent telephone company based in Bemidji, Minnesota, began deploying our
equipment for voice applications in its service area.

     Chibardun Telephone: In April 1999, Chibardun Telephone, an independent
telephone company based in Dallas, Wisconsin, began deploying our equipment for
voice and data applications in its service area.

     Northstar Telephone: In June 1999, Northstar Telephone, a local telephone
company based in Big Lake, Minnesota, began deploying our equipment for voice,
data and video applications in its service area.

                                       43

TECHNOLOGY

     We believe the following key technologies have been instrumental in our
ability to provide what we believe is the world's only integrated, complete
solution for the delivery of integrated voice, data and video services over the
existing telephone copper wires.

     Advanced Application Specific Circuits Architecture.  Applications Specific
Circuits are custom-designed silicon circuits that are optimized for a specific
task or set of tasks. These circuits are critical because they are
performance-optimized to minimize gate counts, packaging size, power dissipation
and cost. In addition, one of these circuits may be the only way to provide a
new or novel function that is not available in an off-the-shelf circuit. Our
engineers have substantial experience in the design of these circuits and have
developed a portfolio of over 15 of these circuits, which enables flexible
delivery of voice, data and video from a single system. We will continue to
pursue additional service and system level Application Specific Circuits as a
mechanism for protecting our intellectual property and to achieve ongoing cost
reductions.

     System Design and Integration Expertise.  We employ a team of experienced
system design and integration engineers in our research and development group.
These individuals provide research, design and development resources and ensure
that our products are able to be integrated by our customers. System integration
by our customers is required on our-specific access products, equipment at the
customers home or business, and management systems, as well as the integration
of our products into our customers' networks. System integration expertise is
critical to the successful deployment of new advanced full service
telecommunications systems and services by our customers.

     Wavelength Division Multiplexing Technology.  Our system uses a technology
known as wavelength division multiplexing. This technology allows multiple
optical signals to be carried on the same optical fiber. In particular, this
technology is used to communicate two-way voice, data and video over a single
optical fiber. This enables our customers to save fiber costs and increase
bandwidth.

     Software and Protocol Stacks.  Most of the system software in our products
has been developed internally using modern design principles and processes.
Where appropriate, various third-party software packages have been integrated
into the access system. Some examples include the real time operating system,
various protocol stack software packages.

     Standards-based Architecture.  We support multiple industry standards to
minimize interoperability issues and leverage industry hardware and software
capabilities, and improve time to market. On the customer side of the network,
we are working with industry standards for asynchronous digital subscriber line
and very high speed digital subscriber line standards to support various
equipment at the customer's home or business.

RESEARCH AND DEVELOPMENT

     As of September 30, 1999, we had 215 full time employees and 15 full time
contractors engaged in research and development. We believe that our future
success depends on our ability:

     - to adapt to the rapidly changing telecommunications environment;

     - to maintain our expertise in core technologies; and

     - to continue meeting and anticipating the evolving needs of telephone
       companies.

                                       44
<PAGE>   49

     We continually review and evaluate technological changes affecting the
telecommunications market and invest substantially in applications-based
research and development. We are committed to an ongoing program of new product
development that combines internal development efforts with strategic
relationships and licensing or marketing arrangements relating to new products
and technologies from outside sources.

     We have focused our research and development expenditures for the past
several years on creating a complete solution for the delivery of voice, data
and video services using the existing infrastructure of telephone companies. We
have also concentrated on developing the associated customer premises equipment,
including our Residential Gateway, and on developing our N(3) View-1 Element
Management Systems. For the years ended December 31, 1996, 1997 and 1998 and the
nine months ended September 30, 1999, research and development expenses were
$17.1 million, $37.1 million, $47.1 million and $35.9 million. We believe that
our extensive experience in designing and implementing high-quality network
components has enabled us to develop integrated systems solutions. We seek to
constantly improve our existing products, including developing additional home
and office products and higher speed interfaces for our products.

SALES AND MARKETING

     We primarily market and sell our products through a direct sales force
located in North America that consisted of 34 people as of September 30, 1999.
To date, sales activities have been focused primarily on the regional Bell
operating companies and GTE. More recently, we have focused on emerging
opportunities within the local, independent and international telephone markets.
We are currently expanding our sales organization to focus on these emerging
customer opportunities. As of September 30, 1999, 12 sales people were focused
solely on sales to local telephone companies. Because of the potential
importance of our products to our customers' networks, we focus our selling
efforts at many levels within each customer's organization.

     We have a variety of marketing programs and initiatives to support the sale
and distribution of our products. As of September 30, 1999, we had 18 full time
employees engaged in marketing activities focusing on reaching technical experts
within telephone companies and creating product awareness and credibility for
our systems among telephone companies. A key factor to building brand awareness
for our products is promoting the success of our customers deploying our
products. We seek to educate telephone companies regarding the benefits of
deploying broadband-ready equipment across a diverse subscriber base. We also
build our brand name through continued publicity and referral efforts in both
media and industry-centered activities, including editorial presence in various
trade magazines, press releases, public speaking opportunities, national and
regional trade show participation, advertising, Internet-based communication and
promotion, media sponsorships and participation in industry standards
activities.

MANUFACTURING

     We seek to deliver our products on time and defect-free by capitalizing on
the experience and expertise of strategic contract manufacturers. Based on their
quality assurance and strengths in the volume manufacture of our products, we
have established our primary contract manufacturing relationships with SCI
Systems and CMC Industries. SCI Systems is responsible for manufacturing a
majority of our circuit board plug-in assemblies. CMC Industries, which was
recently acquired by ACT Manufacturing, is

                                       45
<PAGE>   50

responsible for manufacturing our Residential Gateway product. Using contract
manufacturers allows us to reduce the costly investment in manufacturing
capital, achieve economies of scale in purchasing selected components and reduce
inventory warehousing.

     We maintain only a limited in-house manufacturing capability for final
assembly, testing and integration of our products. Our internal manufacturing
expertise is focused on product design for testability, design for
manufacturability and the transfer of products from development to
manufacturing. Each contract manufacturer typically assembles an account team of
personnel representing all the essential functions to deliver products from
prototype through volume production. This team works with our design, test, and
manufacturing engineers, and our quality, materials, logistics and program
management teams. All of our major contract manufacturers are certified under
international quality standards. Although our contract manufacturers manage
material procurement for the majority of the components that are incorporated in
our products, we continue to manage the evaluation and selection of certain key
components.

     Our engineering team designs circuits and tests these designs using
computer simulations. When the fundamental design is stable, our outsourced
manufacturers make the circuits for testing. Upon completion of these tests,
vendors such as Oki Semiconductor, Broadcom, STMicroelectronics, VLSI (Philips)
and Motorola manufacture the circuit in volume. Warranty and repair support is
performed off-site by our contract manufacturers and by us at our Rohnert Park,
California facility.

CUSTOMER SERVICE AND SUPPORT

     We believe that successful long-term relations with our customers require a
service organization committed to customer satisfaction. As of September 30,
1999, we had 16 technical support employees at our headquarters or in the field.
We also offer a five-day training course for all new customers prior to
receiving and installing a system. To date, revenues from customer service and
support have been immaterial.

     We provide direct support by telephone or at a customer's office or other
location at any time. To monitor service activities, we maintain a customer call
tracking system. We also maintain a dial-up analog modem connection or an
Internet-based management interface to our equipment to assist with diagnostics.

COMPETITION

     The market for providing equipment for local telecommunications networks is
extremely competitive. The principal competitive factors in this market include,
or are likely to include:

     -  product performance and price;

     -  features and reliability;

     -  technical support and service;

     -  relationships with phone companies and systems integrators;

     -  compliance with industry standards;

     -  compatibility with the products of other suppliers;

                                       46
<PAGE>   51

     -  sales and distribution capabilities;

     -  strength of brand name;

     -  long-term cost of ownership to communications providers; and

     -  general industry and economic conditions.

Many of our current and potential competitors have longer operating histories
and greater name recognition and resources than we do. These competitors may
undertake more extensive marketing campaigns than we do. In addition, these
competitors may adopt more aggressive pricing policies than we do. Also, these
competitors may devote substantially more resources to developing new products
than we do. Many of our competitors have recently been acquired and now have
even greater resources to compete with us.

     Our significant current and potential competitors include Advanced Fibre
Communications, Alcatel, Cisco Systems, Efficient Networks, Ericsson, Lucent
Technologies, Nokia, Nortel Networks, RELTEC Corporation (recently acquired by
GEC Marconi), Scientific Atlanta, Siemens and our largest stockholder, General
Instrument. Some of these competitors have existing relationships with our
current and prospective customers which could give them a competitive advantage
over us as a preferred provider. In addition, we anticipate that other large
companies, such as Matsushita Electric Industrial (which markets products under
the Panasonic brand name), Microsoft, Network Computer, Philips, Sony Corp.,
STMicroelectronics and Toshiba America, will likely introduce products that
compete with our Residential Gateway product in the future.

     In addition, we are likely to face increasing competition from alternative
technologies. In particular, cable operators are currently deploying products
that deliver voice, high-speed data and video services over cable. Cable service
providers that offer these packaged services will give subscribers the
alternative of purchasing all communications services from a single service
provider. If these services are implemented successfully, they will compete
directly with the services offered by telephone companies using our products.

     Consolidation in the telecommunications equipment industry may strengthen
our competitors' position in our market. Consolidation of our competitors has
occurred and we expect it to continue to occur in the foreseeable future. For
example, Alcatel acquired DSC Communications, Lucent recently acquired Ascend
Communications and GEC Marconi has recently acquired RELTEC Corporation.
Acquisitions such as these further strengthen our competitors' financial,
technical and marketing resources and provide access to regional Bell operating
company customers. As a result, these competitors are able to devote greater
resources to the development, promotion, sale and support of their products.
This consolidation may allow some of our competitors to penetrate new markets
that we have targeted, such as the domestic local, independent and international
telephone markets. If our competitors are successful in these markets, our
business, operating results and financial condition will be harmed.

INTELLECTUAL PROPERTY

     We rely on a combination of patent, copyright and trademark laws, and on
trade secrets, confidentiality provisions and other contractual provisions to
protect our intellectual property. These measures afford only limited
protection. As of September 30, 1999, we had 11 issued U.S. patents and 23
pending U.S. patent applications and 96 pending international patent
applications.

                                       47

REGULATION OF CUSTOMERS

     Although our products are not now directly subject to significant
regulation by the FCC or any other federal or state communications regulatory
agency, our customers and their networks, into which our products are
incorporated, are subject to government regulation. Accordingly, the effects of
regulation on our customers may, in turn, harm our business, operating results
and financial condition. FCC regulatory policies affecting either the
willingness or the ability of cable operators or telephone companies to offer
certain services, or the terms on which these companies offer the services and
conduct their businesses, may impede sales of our products.


     Several FCC regulatory policies may affect the degree to which or way in
which incumbent local exchange carriers, which we refer to as incumbent
carriers, principally the regional Bell operating companies, can or choose to
make integrated voice, data and video offerings available. For example, the
Telecommunications Act of 1996 requires incumbent carriers to offer their
competitors cost-based access to certain parts of their networks to enable these
competitors to provide telecommunications services. In response to a decision by
the Supreme Court overturning the FCC's rule identifying the specific network
elements that incumbent carriers must offer to their competitors, the FCC
recently announced that, except in limited circumstances, it will not require
incumbent carriers to offer their competitors access to the facilities and
equipment used to provide high-speed data services. The full text of the FCC's
decision has not yet been released, and thus we cannot analyze completely how
this decision affects us. Also, judicial appeals of this recent FCC decision may
follow. The 1996 Telecommunications Act also requires incumbent carriers to
offer for resale, at wholesale rates, any telecommunications services that
incumbent carriers offer to customers. The FCC has determined that high-speed
data services are "telecommunications services," and thus incumbent carriers
must offer high-speed data services for resale by competitors.


     The uncertainties caused by pending regulatory proceedings or appeals could
cause potential customers to delay purchasing decisions. In addition, the
outcomes of the various regulatory proceedings may cause potential customers to
not deploy all of the services for which our products are designed or to delay
the widespread introduction of one or more of these services. Certain members of
Congress have also expressed an interest in reducing the regulation of incumbent
carriers' provision of video and high-speed data services, but again there is no
way to predict whether this legislation will be adopted.


     The FCC also has proposed allowing incumbent carriers to offer high-speed
data and video services through a structurally separate subsidiary that is not
subject to the unbundling and resale requirements. Our equipment is designed to
allow carriers to provide video, high-speed data, and digital voice on an
integrated basis. If incumbent carriers choose to offer video or data services
through a separate affiliate, incumbent carriers may prefer vendors whose
equipment does not provide for integration of service offerings. A separate
affiliate may choose to purchase less sophisticated equipment because it might
not be able to utilize fully our equipment's integrated features. We will not
know for certain the FCC's position on this issue until the full text of the
FCC's decision on the proposed separate affiliate requirement is released. In a
separate proceeding, the FCC recently released an order requiring two large
incumbent carriers, SBC and Ameritech, to provide high-speed data services
through a separate subsidiary as a condition to the FCC's approval of their
merger. Under the terms of the order, this condition terminates when the two
incumbent carriers satisfy certain requirements, but no sooner than 42 months
after the merger's closing.


                                       48
<PAGE>   53

     The FCC's rules prohibit incumbent carriers from providing voice or data
services along with customer premises equipment, such as our Residential
Gateway, as a package offering at a single price. The FCC also currently
prohibits certain carriers, including incumbent carriers, from offering enhanced
services. This would include, for example, Internet access services bundled with
local exchange voice services. These bundling restrictions may limit the ability
of incumbent carriers using our equipment to attract customers. The FCC is
considering amending or repealing these bundling restrictions, but there can be
no assurance that rule changes will take place.

     Distribution of our Residential Gateway could be adversely affected by the
FCC's "navigation devices" rules. Those rules require video program
distributors, including those who use our system to deliver video, to allow
set-top boxes and other navigation devices owned by customers or manufactured by
third parties to be connected to the video program distributor's system. The
rules require video program distributors to disclose technical details of their
interfaces so as to permit third-parties to manufacture the navigation devices
and retail customers to connect them. We believe these rules are not readily
applicable to our system because our Residential Gateway is in many ways
different from a cable set-top box, and currently there is little likelihood of
an independent market for our Residential Gateway separate from our entire
system. However, if these rules could be applied to our Residential Gateway or
other parts of our system, our customers might be required to disclose
proprietary technical information including patented data about our technology,
to allow competing vendors to access the system.

LITIGATION

     In April 1995, DSC Communications and DSC Technologies filed an action
against us and our founders, who are former DSC employees, in the United States
District Court for the Eastern District of Texas alleging breach of contract,
usurpation of corporation opportunity and misappropriation of trade secrets. The
complaint alleged that certain telecommunications technology known as switched
digital video was misappropriated by the defendants. Following a March 1996
trial on the merits, the jury found against the defendants on all three theories
and the court awarded DSC $136.7 million in damages based on future lost
profits. Following several post-trial proceedings and an appeal of a federal
district court's denial of injunctive relief, on February 28, 1997, the United
States Court of Appeals for the Fifth Circuit ruled that DSC was not entitled to
permanent injunctive relief, since the lost profits damage award was based on
the assumption that we developed a competing switched digital video system.
Subsequently, we satisfied the judgment of the Texas litigation, including
interest, by paying DSC $141.0 million in November 1997.

     In March 1998, DSC filed an action against Next Level Communications L.P.,
Spencer Trask Investors LLC, General Instrument and Spencer Trask & Co., Inc.,
the parent of the general partner, in the Superior Court of the State of
Delaware in and for New Castle County. In that action, DSC alleged that in
connection with the formation of Next Level Communications L.P. and the transfer
to it of the switched digital video technology, Next Level Communications L.P.
and Spencer Trask Investors LLC misappropriated DSC's trade secrets; that
General Instrument improperly disclosed trade secrets when it conveyed this
technology to the partnership; and that Spencer Trask & Co. conspired to
misappropriate DSC's trade secrets. The trade secrets at issue were the same
switched digital video technology trade secrets at issue in the Texas
litigation. DSC sought actual damages for the defendants' purported unjust
enrichment, disgorgement of consideration, exemplary damages

                                       49
<PAGE>   54

and attorney's fees, all in unspecified amounts. In April 1998, the defendants
filed an action in the United States District Court for the Eastern District of
Texas, requesting that the federal court preliminarily and permanently enjoin
DSC from prosecuting the Delaware action because by pursuing the action, DSC
effectively was trying to circumvent and relitigate the Texas action, in which
we had paid $141.0 million. In May 1998, the Texas court granted a preliminary
injunction preventing DSC from proceeding with the Delaware action. That
injunction order was appealed to the United States Court of Appeals for the
Fifth Circuit. In June 1999, the Fifth Circuit affirmed the grant of the
preliminary injunction. On July 15, 1999, the Texas federal court granted the
Delaware defendants' motion for summary judgment and issued its final judgment,
permanently enjoining DSC from prosecuting and continuing the Delaware action.

     In May 1998, actions by BroadBand Technologies, Inc. against General
Instrument and by Next Level Communications against BroadBand Technologies,
pending in the United States District Court for the Eastern District of North
Carolina, were dismissed with prejudice. The action brought by BroadBand related
to fiber optic communications systems for delivering television signals and a
patent held by BroadBand. The action brought by Next Level Communications
involved contentions that BroadBand infringed two patents held by Next Level
Communications relating to video compression and signal processing and that
BroadBand had violated antitrust laws. These dismissals were entered pursuant to
a settlement agreement under which, among other things, Next Level
Communications L.P. paid BroadBand Technologies $5.0 million, which was expensed
in 1998, and BroadBand Technologies and Next Level Communications L.P. have
entered into a perpetual cross-license of patents applied for or issued
currently or through May 2003.

EMPLOYEES

     As of September 30, 1999, we had a total of 359 full-time employees and 27
full-time contractors. Of the total number of employees, 215 were in research
and development, 18 in marketing, 25 in operations, 50 in sales and sales
support and 51 in administration. Of the total number of contractors, 15 were in
research and development, one in marketing, one in operations, seven in
administration and three in sales and sales support. Our employees are not
represented by any collective bargaining agreement with respect to their
employment, and we have never experienced an organized work stoppage. Our future
success is heavily dependent upon our ability to hire and retain qualified
technical, marketing and management personnel. The competition for personnel is
intense, particularly for engineering personnel.

FACILITIES

     We lease approximately 205,000 square feet of administrative, research and
development, engineering and prototype/test facilities in Rohnert Park,
California. We also lease two sales offices, in Braintree, Massachusetts and
Denver, Colorado. In addition, we lease an office for our technology department
in Parsippany, New Jersey. We believe our current facilities will be sufficient
to handle our operations for at least the next 18 months.

OPTION GRANTS IN LAST FISCAL YEAR

     The following table contains information concerning the stock option grants
made to each of the named executive officers in fiscal year 1998. No stock
appreciation rights were granted to these individuals during that year.

     Each of the option grants shown in the table was made under the Amended and
Restated 1997 Long-Term Incentive Plan. One-third of these options vests on each
of the first three anniversaries of the date of grant. The options vest in full
if we are subject to a change in control. Absent a change in control, none of
our options is exercisable before the completion of this offering. Once this
offering has been completed, our options will be exercisable in accordance with
their respective vesting schedules. These options may

                                       55

terminate before their expiration dates if the optionee's status as an employee
is terminated or upon the optionee's death or disability.

</TABLE>


     In fiscal year 1998, we granted options to employees to purchase an
aggregate of 179,080 shares. The exercise price was equal to the fair market
value of our common stock as valued by the board of directors of the limited
partner of Next Level Communications L.P. on the date of grant. In determining
the fair market value of our common stock, the board of directors considered
factors such as our financial condition and business prospects, our operating
results, the absence of a market for our common stock and the risks normally
associated with high-technology companies. The exercise price may be paid in
cash, check, shares of our common stock, through a cashless exercise procedure
involving same-day sale of the purchased shares or any combination of these
methods.


     The potential realizable value is calculated based on the ten-year term of
the option at the time of grant. Stock price appreciation of 5% and 10% is
assumed pursuant to rules promulgated by the Securities and Exchange Commission
and does not represent our prediction of our stock price performance. The
potential realizable value at 5% and 10% appreciation is calculated by assuming
that the estimated value on the date of this offering (based on an assumed
initial public offering price of $18.00 per share) appreciates at the indicated
rate for the entire term of the option and that the option is exercised at the
exercise price and the shares sold on the last day of its term at the
appreciated price.

AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION
VALUES

     The following table sets forth information concerning the shares acquired
and the value realized upon the exercise of stock options during fiscal year
1998 and the year-end number and value of unexercised options with respect to
each of the named executive officers. No stock appreciation rights were
exercised by the named executive officers in fiscal year 1998 or were
outstanding at the end of that year.

     Some of our options were granted in tandem with options to purchase shares
of the common stock of General Instrument. If all or a portion of one of our
options are exercised, all or a portion of the General Instrument options are
canceled, and if all or a portion of the General Instrument options are
exercised, all or a portion of our options are canceled. The number of
unexercised options set forth in the table does not include options to purchase
shares of General Instrument common stock.

</TABLE>


     The value of "in-the-money" stock options represents the positive spread
between the exercise price of stock options and the fair market value for our
common stock of $9.66 per share as of December 31, 1998. The fair market value
of our common stock was determined by the board of directors of the limited
partner of Next Level Communications L.P. based on a number of factors, such as
our financial condition and business prospects, our operating results, the
absence of a market for our common stock and the risks normally associated with
high-technology companies. The initial public offering price is higher than the
estimated fair market value at fiscal year-end, and the value of unexercised
options would be higher than the numbers shown in the table if the value were
calculated by subtracting the exercise price from the initial public offering
price.

EMPLOYEE STOCK PLANS

  1999 STOCK PLAN


     Our board of directors adopted our 1999 Stock Plan effective October 1,
1999. Our stockholder also approved this plan. We have reserved 6,000,000 shares
of our common stock for grants under the 1999 Stock Plan. If options or shares
awarded under the 1999 Stock Plan are forfeited, then those options or shares
will become available for new awards. We have granted options covering 5,393,854
shares of our common stock under the 1999 Stock Plan. These options have an
exercise price equal to $11.00 per share, and they will become exercisable with
respect to 25% of the shares after 12 months of service and the remaining 75% of
the shares in equal monthly installments over the next 36 months of service. We
will make no awards under the 1999 Stock Plan after this offering.


     Our board of directors administers the 1999 Stock Plan. The board has
complete discretion to make all decisions relating to the interpretation and
operation of our 1999

                                       57
<PAGE>   62

Stock Plan. Participants in the plan may include employees, consultants and
members of the board of directors who are not employees. The board may grant
options to purchase shares of our common stock, or it may grant restricted
shares of our common stock. Options may be incentive stock options, which may
qualify for favorable tax treatment and which have a minimum exercise price
equal to 100% of the fair market value of the underlying stock on the date of
grant. Options may also be nonstatutory stock options, which cannot qualify for
favorable tax treatment and which have a minimum exercise price equal to 85% of
the fair market value of the underlying stock on the date of grant. Options
expire not later than 10 years after the date of grant, and they expire earlier
if the optionee's service ends earlier.

     Our board of directors may amend or terminate the 1999 Stock Plan at any
time. If our board amends the plan, stockholder approval must be obtained only
to the extent required by applicable law.

  1999 EQUITY INCENTIVE PLAN

     Our board of directors adopted our 1999 Equity Incentive Plan on October
10, 1999. Our stockholder also approved this plan. We have reserved 4,000,000
shares of our common stock for issuance under the 1999 Equity Incentive Plan. In
addition, any shares reserved under the 1999 Stock Plan for options not granted
at the time of this offering will become available for grants under the 1999
Equity Incentive Plan. In general, if options or shares awarded under the 1999
Stock Plan or the 1999 Equity Incentive Plan are forfeited, then those options
or shares will again become available for awards under the 1999 Equity Incentive
Plan. We have not yet granted any options under the 1999 Equity Incentive Plan,
and none will be granted until after this offering.

     The compensation committee of our board of directors administers the 1999
Equity Incentive Plan. The committee has the complete discretion to make all
decisions relating to the interpretation and operation of our 1999 Equity
Incentive Plan. The committee has the discretion to determine who will receive
an award, what type of award it will be, how many shares will be covered by the
award, what the vesting requirements will be, if any, and what the other
features and conditions of each award will be. The compensation committee may
also reprice outstanding options and modify outstanding awards in other ways.

     The following groups of individuals are eligible to participate in the 1999
Equity Incentive Plan:

     - employees;

     - members of our board of directors, other than board members who are our
       employees or board members who are employees of General Instrument or its
       affiliates; and

     - consultants.

     The 1999 Equity Incentive Plan provides for the following types of awards:

     - options to purchase shares of our common stock;

     - stock appreciation rights;

     - restricted shares of our common stock; and

     - stock units (sometimes called phantom shares).

                                       58
<PAGE>   63

     Options may be incentive stock options or nonstatutory stock options. An
optionee who exercises an incentive stock option may qualify for favorable tax
treatment under Section 422 of the Internal Revenue Code of 1986. On the other
hand, nonstatutory stock options do not qualify for this favorable tax
treatment. The exercise price for all options granted under the 1999 Equity
Incentive Plan may not be less than 100% of the fair market value of our common
stock on the option grant date. Optionees may pay the exercise price by using:

     - cash;

     - shares of common stock that the optionee already owns;

     - an immediate sale of the option shares through a broker designated by us;
       or

     - a loan from a broker designated by us, secured by the option shares.

     Options and stock appreciation rights vest at the time or times determined
by the compensation committee. In most cases, our options will vest over the
four-year period following the date of grant. Options and stock appreciation
rights generally expire 10 years after they are granted, except that they
generally expire earlier if the optionee's service terminates earlier.

     The 1999 Equity Incentive Plan provides that no participant may receive
options or stock appreciation rights covering more than 2,000,000 shares in the
same year, except that a newly hired employee may receive options or stock
appreciation rights covering up to 3,000,000 shares in the first year of
employment.

     Restricted shares may be awarded under the 1999 Equity Incentive Plan in
return for:

     - cash;

     - a full-recourse promissory note, except that the par value of newly
       issued shares must be paid in cash;

     - services already provided to us; and

     - in the case of treasury shares only, services to be provided to us in the
       future.

     Restricted shares and stock units vest at the time or times determined by
the compensation committee.

     Our compensation committee may determine that an option or other award
under the 1999 Equity Incentive Plan will become fully or partially vested if we
are subject to a change in control or if a participant's employment is
terminated after a change in control. A change in control includes the
following, except that in no case does a change in control include the sale of
our stock by General Instrument or General Instrument's pending merger with
Motorola or any other change in control of General Instrument:

     - a merger after which our own stockholders own 50% or less of the
       surviving corporation or our parent company;

     - a sale of all or substantially all of our assets;

     - a proxy contest that results in the replacement of more than one-half of
       our directors over a 24-month period; or

     - an acquisition of 50% or more of our outstanding stock by any person or
       group, other than General Instrument or a person related to us, such as a
       holding company owned by our stockholders.

                                       59
<PAGE>   64

     The non-employee members of our board of directors, with the exception of
non-employee directors who are employees of General Instrument or its
affiliates, will be eligible for automatic option grants under the 1999 Equity
Incentive Plan. Each non-employee director who first joins our board after the
completion of this offering will receive an initial option for 20,000 shares of
our common stock. That grant will occur when the director takes office. The
initial option will vest over the four-year period following the date of grant.

     At the time of each of our annual stockholders' meetings, beginning in
2000, each non-employee director, with the exception of non-employee directors
who are employees of General Instrument or its affiliates, who will continue to
be a director after that meeting will automatically be granted an annual option
for 5,000 shares of our common stock. However, a new non-employee director who
is receiving the 20,000-share initial option will not receive the 5,000-share
annual option in the same year. The annual options will vest one year after the
date of grant. If a change in control occurs, or if a non-employee director
leaves our board because of retirement after age 65, total disability or death,
then the non-employee director's options granted under the 1999 Equity Incentive
Plan will become fully vested.

     The exercise price of each non-employee director's option will be equal to
the fair market value of our common stock on the option grant date. A director
may pay the exercise price by using cash, shares of common stock that the
director already owns, or an immediate sale of the option shares through a
broker designated by us. The non-employee directors' options have a 10-year
term, except that they expire one year after a director leaves the board (if
earlier).

     Our board may amend or terminate the 1999 Equity Incentive Plan at any
time. If our board amends the plan, it does not need to ask for stockholder
approval of the amendment unless applicable law requires it. The 1999 Equity
Incentive Plan will continue in effect indefinitely, unless the board decides to
terminate the plan earlier.

     1999 EMPLOYEE STOCK PURCHASE PLAN

     Our board of directors adopted our 1999 Employee Stock Purchase Plan on
October 10, 1999. Our stockholder also approved this plan. Our 1999 Employee
Stock Purchase Plan is intended to qualify under Section 423 of the Internal
Revenue Code. We have reserved 1,000,000 shares of our common stock for issuance
under the plan. On November 1 of each year, starting with the year 2000, the
number of shares in the reserve will automatically be increased by 1,000,000
shares, 1% of the shares then outstanding or the number determined by our board
of directors, whichever is lowest. The plan will be administered by the
compensation committee of our board of directors.

     All of our employees are eligible to participate. Eligible employees may
begin participating in the 1999 Employee Stock Purchase Plan at the start of any
offering period. Each offering period lasts 24 months. Overlapping offering
periods start on May 1 and November 1 of each year. However, the first offering
period will start on the effective date of this offering and end on October 31,
2001.

     Our 1999 Employee Stock Purchase Plan permits each eligible employee to
purchase common stock through payroll deductions. Each employee's payroll
deductions may not exceed 20% of the employee's cash compensation. Purchases of
our common stock will occur on April 30 and October 31 of each year. Each
participant may purchase up to

                                       60
<PAGE>   65

1,500 shares on any purchase date. But the value of the shares purchased in any
calendar year (measured as of the beginning of the offering period) may not
exceed $25,000.

     The price of each share of common stock purchased under our 1999 Employee
Stock Purchase Plan will be 85% of the lower of:

     - the fair market value per share of common stock on the date immediately
       before the first day of the applicable offering period; or

     - the fair market value per share of common stock on the purchase date;

     In the case of the first offering period, the price per share under the
plan will be 85% of the lower of:

     - the price per share to the public in this offering; or

     - the fair market value per share of common stock on the purchase date.

     Employees may end their participation in the 1999 Employee Stock Purchase
Plan at any time. Participation ends automatically upon termination of
employment with us. If a change in control occurs, our 1999 Employee Stock
Purchase Plan will end and shares will be purchased with the payroll deductions
accumulated to date by participating employees, unless the plan is assumed by
the surviving corporation or its parent. Our board of directors may amend or
terminate the 1999 Employee Stock Purchase Plan at any time. If our board
increases the number of shares of common stock reserved for issuance under the
plan (except for the automatic increases described above), it must seek the
approval of our stockholders.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Currently, Next Level Communications, a subsidiary of General Instrument,
is the limited partner and Spencer Trask is the general partner of Next Level
Communications L.P., with the General Instrument subsidiary holding a 90.4%
limited partnership interest and Spencer Trask holding a 9.6% general
partnership interest. General Instrument also holds a $75.0 million principal
amount promissory note of Next Level Communications L.P., which, together with
accrued interest thereon, is convertible into shares of common stock of the
successor corporation to the partnership. Affiliates of Spencer Trask also have
an option to acquire additional shares of that successor corporation.


     Immediately prior to the completion of this offering, General Instrument
will contribute the $75 million note and accrued interest thereon to us, and
Next Level Communications L.P. and the General Instrument subsidiary will be
merged into us. As a result, General Instrument will receive an estimated
65,074,573 shares of common stock and Spencer Trask will receive 5,863,329
shares of common stock. After giving effect to this offering, these shares will
represent approximately 89.3% of the outstanding common stock. Also pursuant to
this merger, the option held by Spencer Trask affiliates will become warrants to
acquire from us 8,480,102 shares of common stock at an exercise price of $10.38
per share. The warrants become exercisable upon completion of this offering and
expire on January 13, 2003. In lieu of paying the exercise price in cash, the
holders may elect to receive, upon the exercise of a warrant, the number of
shares subject to the warrant multiplied by a fraction, the numerator of which
is the market price per share less the exercise price and the denominator of
which is the market price per share.


     Prior to this offering, General Instrument will enter into a voting trust
agreement, which is described below, to limit its voting power to 49% of the
voting power of all outstanding common stock and to limit the number of its
designees to the board of directors to one less than a majority. Notwithstanding
the voting trust agreement, as a result of its 49% voting power and board
representation, General Instrument will be able to exercise significant
influence over the business and affairs of Next Level, including dividend
policy, borrowings and access to capital, acquisition or disposition of assets,
mergers and other business combinations and change of control transactions.

     On September 14, 1999, General Instrument entered into an agreement and
plan of merger with Motorola. Immediately upon the completion of this pending
merger, General Instrument intends to terminate the voting trust agreement and
appoint a number of additional individuals to our board of directors sufficient
to exercise control of us. Accordingly, upon the completion of this pending
merger, Motorola will be able to exercise a majority of our total voting power
and will have the ability to control our board of directors and all matters
relating to our business and affairs. We do not know whether Motorola's plans
for our business and affairs will be different than our existing plans and
whether any changes that may be implemented under Motorola's control will be
beneficial or detrimental to our other stockholders.

     General Instrument and Spencer Trask have advised us that they currently
intend to hold all of their shares. However, they are not subject to any
contractual obligation to retain any of their shares, except that they have
agreed not to sell or otherwise dispose of any shares for 180 days after the
date of this prospectus without the prior written consent of Credit Suisse First
Boston Corporation. As a result, we cannot assure you as to how long General
Instrument or Spencer Trask will maintain their beneficial ownership of common
stock after this offering.

                                       62
<PAGE>   67

     It is possible that General Instrument or Motorola could be in a position
involving a conflict of interest with us. In addition, individuals who are
officers or directors of both our principal stockholder and us may have
fiduciary duties to both our principal stockholder and us. For example, a
conflict may arise if our principal stockholder were to engage in activities or
pursue corporate opportunities that may overlap with our business. Our
certificate of incorporation contains provisions intended to protect our
principal stockholder and these individuals in these situations. See
"Description of Capital Stock -- Other Certificate of Incorporation and By-law
Provisions -- Corporate Opportunities."

     General Instrument leases one of the buildings at our Rohnert Park offices
from a Delaware realty trust set up specifically to permit the purchase and
lease of the facility. To purchase the land and construct the facility, this
trust obtained loans from several lenders which are guaranteed by General
Instrument. We intend to sublease the facility from General Instrument
immediately prior to the completion of this offering and will remain a
sublessee. General Instrument will remain lessee of the facility and guarantor
of the loans. We have the right to purchase the property by refinancing the
outstanding indebtedness. If we do so, General Instrument would be released from
the obligations under the loans. Under the terms of our proposed sublease with
General Instrument, until December 31, 1999, we will pay directly to the trust
all monthly payments owed by General Instrument on the facility. If we have not
refinanced the loans by that date, we will pay to General Instrument a fair
market rent of not less than the amount payable by General Instrument under its
lease. In addition, we also have the option to purchase the building from
General Instrument following December 31, 1999 at fair market value.

     As a condition of our contract with Bell Atlantic, we are required to
maintain up to a $75 million performance bond or irrevocable letter of credit.
This obligation, currently $25 million, is guaranteed by General Instrument. We
are negotiating to replace this guarantee with a facility of our own.

     Set forth below are descriptions of agreements which will be entered into
between us and our principal stockholders in connection with this offering.

CORPORATE AND INTERCOMPANY AGREEMENT

     Before this offering is completed, we will enter into a corporate and
intercompany agreement with General Instrument under which we will grant to
General Instrument and its affiliates a continuing option to purchase additional
shares of common stock or shares of non-voting capital stock. If we issue any
additional equity securities after this offering, General Instrument and its
affiliates may exercise this option to purchase:

     - shares of common stock to the extent necessary for them to maintain their
       then-existing percentage of the total voting power; and

     - shares of nonvoting capital stock to the extent necessary to own 80% of
       any class of non-voting capital stock which may be outstanding.

The purchase price of the shares of common stock will be the market price of the
common stock. The purchase price of non-voting capital stock will be the price
at which third parties may purchase this stock. The stock option expires if
General Instrument and its affiliates beneficially own less than 30% of the
outstanding common stock.

     Under this agreement, we have agreed to obtain a release of General
Instrument from its Bell Atlantic guaranty as promptly as practicable and in any
event not later than December 31, 1999.

                                       63
<PAGE>   68

     This agreement will also provide that, for as long as General Instrument
and its affiliates beneficially own a majority of the outstanding common stock,
we may not take any action which may be reasonably anticipated to result in a
violation by them of:

     - any law or regulation, including the Internal Revenue Code or the
       Employee Retirement Income Security Act;

     - their certificates of incorporation or by-laws;

     - any credit agreement or other material instrument binding upon them or
       any of their assets; or

     - any judgment, order or decree of any governmental authority having
       jurisdiction over them or any of their assets.

This agreement will also provide that the parties will provide reasonable
cooperation with respect to their tax filings and any tax audits. Under this
agreement, we will also indemnify General Instrument and its affiliates against
any lawsuits or other claims arising out of any of our or our predecessors'
activities or omissions before and after this offering.

     This agreement will also provide that, immediately upon the termination of
the voting trust agreement, we and our board of directors will take all actions
necessary to appoint on the date of termination any number of additional
directors nominated by General Instrument.

     This agreement will also provide that we will enter into a similar
agreement for the benefit of any Majority Transferee, as defined under
"Description of Capital Stock."

CROSS LICENSE AGREEMENT

     Before this offering is completed, we will enter into a cross license
agreement with General Instrument. Under this agreement, General Instrument will
grant to us a nonexclusive, perpetual, royalty free, worldwide license under all
patent applications and patents owned by General Instrument and filed prior to
this offering and any future patents issued from these General Instrument
patents and patent applications, to make our NLevel(3) product or related
switched digital video network equipment and software. This grant will not
include patent claims covering the implementations, methods or devices primarily
used or to be used by General Instrument. Also under this agreement, we will
grant to General Instrument and its affiliates, including Motorola upon
completion of General Instrument's pending merger with Motorola, a nonexclusive,
perpetual, royalty free, worldwide license under all patent applications and
patents owned by us and filed prior to this offering and any future patents
issued from these patents and patent applications to make digital cable
subscriber terminals, satellite and wireless subscriber terminals, cable modems,
HFC telephony and related headend, uplink, transmission or other network
equipment and software. This grant will not include patent claims covering the
implementations, methods or devices primarily used or to be used by us. We and
General Instrument will each also license to the other the right to use
confidential, technical and other information in each other's possession as of
the completion of this offering. These licenses do not include the right to
sublicense to any third parties. This agreement will permit General Instrument
and us to transfer their or our licenses pursuant to a sale of their or our
respective entire business, a sale of an entire business unit that benefits from
the license or to any of General Instrument's or our respective affiliates.

<PAGE>   69

REGISTRATION RIGHTS AGREEMENT

     Before this offering is completed, we will enter into a registration rights
agreement with General Instrument and Spencer Trask. Under this agreement, we
will grant to these stockholders and their affiliates the right to request that
we use our best efforts to register their shares of common stock under federal
and state securities laws so that they may sell or dispose of their shares in
accordance with these laws. So long as General Instrument and its affiliates own
30% of our outstanding common stock, they will not be limited in the number of
times they may make that request. After their ownership declines below that
level, they will be able to cause us to effect up to four registrations of their
shares. Spencer Trask and its affiliates will be able to cause us to effect up
to three registrations of their shares. Under customary "piggy-back"
registration rights, General Instrument, Spencer Trask and their affiliates will
also be entitled to include their shares in all registrations of common stock we
make, either for a sale by us or any of our stockholders, subject to customary
exceptions. We will pay for all out-of-pocket expenses relating to these
registrations and indemnify General Instrument, Spencer Trask and their
affiliates against liabilities under securities laws. General Instrument,
Spencer Trask and their affiliates may generally assign these registration
rights to transferees of their shares. This agreement will also provide that we
will enter into a similar agreement for the benefit of any Majority Transferee.

VOTING TRUST AGREEMENT


     Before this offering is completed, we and General Instrument will enter
into a voting trust agreement, which General Instrument intends to terminate
immediately upon the completion of its pending merger with Motorola. ChaseMellon
Shareholder Services LLC will also be a party to this agreement in its capacity
as voting trustee. All of the shares of common stock to be received by General
Instrument pursuant to the recapitalization will be held in the voting trust
created by this agreement. General Instrument may, but is not obligated to,
deposit in the voting trust additional shares from time to time. Through this
agreement, General Instrument intends to limit the voting power of the shares
held in the voting trust to 49% of the total voting power represented by all
outstanding shares of our common stock or a lower percentage as General
Instrument may elect from time to time by giving notice to the voting trustee
and us. We refer to this percentage as the "threshold percentage."


     With respect to the voting trust shares representing up to the threshold
percentage of the total voting power of all outstanding shares of common stock,
the voting trustee will:

     - vote or consent in writing in favor of any individuals designated by
       General Instrument for election as director so long as the number of
       individuals designated by General Instrument and elected to our board of
       directors would not exceed one less than a majority;

     - vote "for" or "against" or abstain from voting on any other matter
       validly presented at a stockholder meeting or consent in writing as
       directed by General Instrument; and

     - cause to be present at any stockholder meeting for purposes of
       determining a quorum a number of those voting trust shares as directed by
       General Instrument, which will not be less than the number of shares
       directed by General Instrument to be voted at that meeting.

                                       65
<PAGE>   70

     With respect to all other voting trust shares, the voting trustee will:

     - vote or consent in writing in favor of any individual for election as
       director in the same proportion as all shares of common stock other than
       the voting trust shares are voted or consented to in writing in favor of
       that individual;

     - vote "for" or "against" or abstain from voting on any other matter
       validly presented at a stockholder meeting or consent in writing in the
       same proportion as all shares of common stock other than the voting trust
       shares are voted "for" or "against" or abstain from voting or consented
       to in writing on that matter; and

     - cause to be present at any stockholder meeting for purposes of
       determining a quorum a number of those voting trust shares which is in
       proportion to the number of shares of common stock other than voting
       trust shares which are present at that meeting in relation to the number
       of outstanding shares of common stock other than the voting trust shares.

     Except as described above, the voting trustee will not exercise any right
or power with respect to the voting trust shares but will instead act solely as
directed by General Instrument. For example, General Instrument may:

     - direct the voting trustee to tender voting trust shares in connection
       with any tender, exchange or other offer and to distribute the
       consideration received for those shares free of the voting trust;

     - sell, assign or otherwise transfer voting trust shares to any person and
       cause certificates for those shares to be delivered, free of the voting
       trust except in the case of a transfer to its subsidiary, to it or to its
       order for that purpose;

     - distribute voting trust shares to its stockholders in a tax-free spin-off
       or otherwise and cause certificates for those shares to be delivered free
       of the voting trust to it for that purpose; or

     - dissent from any corporate action or perfect any dissenters' rights.

     The voting trustee will deliver to General Instrument all dividends, other
than dividends in additional shares of common stock, paid on the voting trust
shares.

     This agreement and the voting trust will terminate on the tenth anniversary
of the closing date and will be irrevocable, except that this agreement and the
voting trust may be terminated by General Instrument if:

     - the voting power represented by the voting trust shares is not more than
       the threshold percentage of the total voting power of all outstanding
       shares of common stock;

     - it beneficially owns 85% or more of all outstanding shares of common
       stock;

     - any person acquires more than 75% of the outstanding shares of common
       stock other than the voting trust shares; or

     - any person acquires more than 50% of the outstanding shares of common
       stock of General Instrument, including pursuant to its pending merger
       with Motorola.

     Notwithstanding the foregoing, General Instrument may assign this agreement
to any transferee of voting trust shares, in which case the voting trust will
continue to remain in effect.

                             PRINCIPAL STOCKHOLDERS

     The following table sets forth as of September 30, 1999, giving effect to
our recapitalization, and as adjusted to reflect the sale of the shares of
common stock in this offering, certain information with respect to the
beneficial ownership of common stock as to:

     - each person known by us to own beneficially more than 5% of the
       outstanding shares of our common stock;

     - each of the named executive officers;


     - each of our current directors; and



     - all of our current directors and executive officers as a group.


     Except as otherwise indicated, and subject to applicable community property
laws, the persons named below have sole voting and investment power with respect
to all shares of common stock held by them.


     Applicable percentage ownership in the table is based on 70,893,309 shares
of common stock outstanding as of September 30, 1999 and 79,393,309 shares of
common stock outstanding immediately following the completion of this offering

30, 1999). Beneficial ownership is determined in accordance with the rules of
the SEC. Shares of common stock subject to options that are presently
exercisable or exercisable within 60 days of September 30, 1999 are deemed
outstanding for the purpose of computing the percentage ownership of the person
or entity holding the options, but are not treated as outstanding for the

address in care of our principal executive offices.

                          DESCRIPTION OF CAPITAL STOCK

     We have summarized below the material terms of our capital stock. We
encourage you to read our certificate of incorporation and by-laws, which we
have filed as exhibits to the registration statement of which this prospectus is
a part.

AUTHORIZED SHARES

     Our authorized capital stock will consist of:


        - 400,000,000 shares of common stock;


        - 70,000,000 shares of Class B non-voting common stock; and

        - 10,000,000 shares of preferred stock.


     Of the 400,000,000 authorized shares of common stock, on the closing date,


        - 8,500,000 shares will be offered in this offering;


        - 65,074,573 shares will be beneficially owned by General Instrument and
          held in the voting trust in connection with our recapitalization;

        - 8,480,102 shares will be reserved for issuance pursuant to outstanding
          warrants held by affiliates of Spencer Trask; and


        - 17,964,904 shares will be reserved for issuance pursuant to our
          employee benefit plans, of which options to purchase 12,358,758 shares
          are outstanding.


     No shares of Class B non-voting common stock will be issued or outstanding
at any time following the completion of this offering. No shares of preferred
stock will be outstanding immediately following the completion of the offering.

COMMON STOCK

     The holders of common stock are entitled to one vote per share on all
matters to be voted on by stockholders. Holders of common stock are not entitled
to cumulate their votes in the election of directors. Election of directors will
be decided by a plurality of the votes cast. Generally, all other matters to be
voted on by stockholders must be approved by the holders of a majority of the
votes entitled to be cast by all shares of common stock present in person or
represented by proxy, subject to any voting rights granted to holders of any
preferred stock.

     Holders of common stock are entitled to dividends, when, as and if,
declared by the board of directors, subject to any preferential rights of any
outstanding preferred stock. If we liquidate, dissolve or wind-up, after payment
in full of the amounts required to be paid to holders of any preferred stock,
holders of common stock are entitled to share ratably in any assets available
for distribution. Shares of common stock are not subject to redemption. Holders
do not have preemptive rights to purchase additional shares of common stock,
although General Instrument and its affiliates have a right to purchase
additional shares under our corporate and intercompany agreement to the extent
necessary

                                       69
<PAGE>   74


to maintain their ownership percentage upon future equity issuances by us,. See
"Certain Relationships and Related Transactions -- Corporate and Intercompany
Agreement."


PREFERRED STOCK

     The preferred stock is issuable from time to time in one or more series and
with the designations and preferences for each series as will be stated in the
resolutions providing for the designation and issue of each series adopted by
our board of directors. Our board of directors is authorized by our certificate
of incorporation to determine, among other things, the voting, dividend,
redemption, conversion and liquidation powers, rights and preferences and the
limitations thereon pertaining to each series of preferred stock. Our board of
directors, without stockholder approval, may issue preferred stock with voting
and other rights that could adversely affect the voting power of the holders of
the common stock and that could have anti-takeover effects. We have no present
plans to issue any shares of preferred stock. The ability of our board of
directors to issue preferred stock without stockholder approval could have the
effect of delaying, deferring or preventing a change in control or the removal
of existing management.

CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS THAT MAY HAVE AN ANTITAKEOVER
EFFECT

     The provisions of our certificate of incorporation and by-laws summarized
below may have an anti-takeover effect and may delay, deter, or prevent a tender
offer or takeover attempt that a stockholder might consider to be in its best
interest, including offers or attempts that might result in a premium being paid
over the market price for its shares.

     Board of Directors

     Our certificate of incorporation provides that our board of directors will
be divided into three classes of directors, with the classes to be as nearly
equal in number as possible. One class will be originally elected for a term
expiring at the annual meeting of stockholders to be held in 2000, another will
be originally elected for a term expiring at the annual meeting of stockholders
to be held in 2001 and another will be originally elected for a term expiring at
the annual meeting of stockholders to be held in 2002. Each director will hold
office until his or her successor is duly elected and qualified. Commencing with
the 2000 annual meeting of stockholders, directors elected to succeed directors
whose terms then expire will be elected for a term expiring at the third
succeeding annual meeting of stockholders after their election, with each
director to hold office until this person's successor is duly elected and
qualified.

     Upon completion of this offering, we expect our board of directors to
consist of five members. Our certificate of incorporation provides that the
number of directors will be fixed from time to time exclusively by resolution
adopted by the affirmative vote of a majority of the entire board of directors,
but will consist of not more than twelve nor less than three directors. In
addition, our certificate of incorporation provides that any vacancies will be
filled by the affirmative vote of a majority of the remaining directors, even if
less than a quorum, or by a sole remaining director, unless the vacancy was
caused by the action of stockholders in which event the vacancy will be filled
by the stockholders and not the directors.

     Under our certificate of incorporation, directors may be removed, with or
without cause, by the affirmative vote of shares representing a majority of the
votes entitled to be

                                       70
<PAGE>   75

cast by the then outstanding shares of common stock. However, after the first
date that General Instrument or a "Majority Transferee," together with their
respective affiliates, ceases to beneficially own at least 49% of the
outstanding shares of common stock, directors may not be removed without cause.
"Majority Transferee" is any transferee or group of related transferees of
General Instrument which is unaffiliated with General Instrument of more than a
majority of the outstanding shares of common stock in a single transaction or a
group of related transactions.

     Our by-laws provide that General Instrument or the Majority Transferee, as
applicable, together with their respective affiliates, shall have the right to
designate at least one member of any committee of our board of directors so long
as it owns beneficially at least 10% of the outstanding shares of common stock.

     Special Meetings of Stockholders; Actions by Written Consent of
Stockholders


     Under our certificate of incorporation, special meetings of stockholders
may be called by certain specified officers or by any officer at the request in
writing of a majority of the board of directors. In addition, but only prior to
the first date that General Instrument or the Majority Transferee, together with
their respective affiliates, ceases to beneficially own at least 49% of the
outstanding shares of common stock, special meetings may also be called by the
holders of a majority of the outstanding shares of common stock. In addition,
our certificate of incorporation will provide that any action required or
permitted to be taken by stockholders may be effected by written consent without
a meeting only prior to that date.


     Business Combinations with Interested Stockholders

     We will not be subject to the business combination provisions of Section
203 of the Delaware General Corporation Law, but our certificate of
incorporation will contain provisions substantially similar to Section 203. In
general, these provisions will prohibit us from engaging in various business
combination transactions with any interested stockholder for a period of three
years after the date of the transaction in which the person became an interested
stockholder unless:

     - the business combination transaction, or the transaction in which the
       interested stockholder became an interested stockholder, is approved by
       our board of directors prior to the date the interested stockholder
       obtained this status,

     - upon consummation of the transaction which resulted in the stockholder
       becoming an interested stockholder, the interested stockholder owned at
       least 85% of our common stock outstanding at the time the transaction
       commenced, excluding for purposes of determining the number of shares
       outstanding those shares owned by:

        - persons who are directors and also officers; and

        - employee stock plans in which employee participants do not have the
          right to determine confidentially whether shares held subject to the
          plan will be tendered in a tender or exchange offer; or

     - on or subsequent to this date the business combination is approved by our
       board of directors and authorized at an annual or special meeting of
       stockholders by the affirmative vote of at least 66 2/3% of our
       outstanding common stock which is not owned by the interested
       stockholder.

                                       71
<PAGE>   76

     Under our certificate of incorporation, a business combination is defined
to include mergers, asset sales and other transactions resulting in financial
benefit to a stockholder. In general, an interested stockholder is a person who,
together with affiliates and associates, owns or, within three years, did own,
15% or more of our common stock. General Instrument and its affiliates,
including Motorola upon the completion of General Instrument's pending merger
with Motorola, and the Majority Transferee and its affiliates will be exempt
from these provisions.

     Advance Notice Procedures

     Our by-laws provide for an advance notice procedure for the nomination,
other than by or at the direction of our board of directors, of candidates for
election as directors as well as for other stockholder proposals to be
considered at annual meetings of stockholders. In general, a written notice of
intent to nominate a director or raise matters at the meetings will have to be
received by us not less than 60 nor more than 90 days prior to the anniversary
of the previous year's annual meeting of stockholders. This notice must contain
information concerning the person to be nominated or the matters to be brought
before the meeting and information concerning the stockholder submitting the
proposal. So long as General Instrument or the Majority Transferee, together
with their respective affiliates, owns beneficially at least 10% of the
outstanding shares of common stock, General Instrument or the Majority
Transferee, as applicable, will be exempt from these advance notice procedures.

     Amendment

     Our certificate of incorporation also provides that, after the first date
that General Instrument or the Majority Transferee, together with their
respective affiliates, ceases to beneficially own at least 49% of the
outstanding shares of common stock, the affirmative vote of the holders of at
least 80% of the outstanding shares of common stock is required to amend the
provisions of our certificate of incorporation described above under "-- Board
of Directors," "-- Special Meetings of Stockholders; Actions by Written Consent
of Stockholders" or "-- Business Combinations with Interested Stockholders."
Under our certificate of incorporation and by-laws, our by-laws may only be
amended:

     - at any time by the affirmative vote of directors constituting not less
       than a majority of the entire board of directors;

     - prior to the first date that General Instrument or the Majority
       Transferee, together with their respective affiliates, ceases to
       beneficially own at least 49% of the outstanding shares of common stock,
       by the affirmative vote of the holders of a majority of the outstanding
       shares of common stock; or

     - after that date, by the affirmative vote of the holders of at least 80%
       of the outstanding shares of common stock.

OTHER CERTIFICATE OF INCORPORATION AND BY-LAW PROVISIONS

     Corporate Opportunities

     Our certificate of incorporation provides that General Instrument will have
no duty to refrain from engaging in the same or similar activities or lines of
business as us, and neither General Instrument nor any of its officers or
directors, except as provided below,

                                       72
<PAGE>   77

will be liable to us or our stockholders for breach of any fiduciary duty solely
by reason of any of these activities. If General Instrument acquires knowledge
of a potential transaction or matter which may be a corporate opportunity for
both General Instrument and us, General Instrument will have no duty to
communicate or offer this corporate opportunity to us. In addition, General
Instrument will not be liable to us or our stockholders for breach of any
fiduciary duty as a stockholder solely by reason of the fact that General
Instrument pursues or acquires this corporate opportunity for itself, directs
this corporate opportunity to another person, or does not communicate
information regarding this corporate opportunity to us.

     If a director or officer of us who is also a director or officer of General
Instrument acquires knowledge of a potential transaction or matter which may be
a corporate opportunity for both us and General Instrument, this individual will
have fully satisfied and fulfilled his or her fiduciary duty to us and our
stockholders with respect to this corporate opportunity if he or she acts in a
manner consistent with the following policy:

     - The corporate opportunity will belong to us if this opportunity is
       expressly offered to the person in writing solely in his or her capacity
       as our director or officer.

     - Otherwise, this opportunity will belong to General Instrument.

     These provisions will expire on the date that General Instrument and its
affiliates cease to own beneficially at least 20% of the outstanding shares of
common stock and no person who is a director or officer of us is also a director
or officer of General Instrument.

     In addition to any vote of the stockholders required by our certificate of
incorporation, until the time that General Instrument and its affiliates cease
to own beneficially at least 20% of the outstanding shares of common stock, the
affirmative vote of the holders of more than 80% of the outstanding shares of
common stock will be required to alter, amend or repeal, or adopt any provision
inconsistent with, the corporate opportunity provisions described above.
Accordingly, so long as General Instrument and its affiliates beneficially own
at least 20% of the outstanding shares of common stock, it can prevent any such
alteration, amendment, repeal or adoption.

     Upon the completion of General Instrument's pending merger with Motorola,
Motorola will also be entitled to the protections of the foregoing provisions to
the same extent as General Instrument.

     Any person purchasing or otherwise acquiring common stock will be deemed to
have notice of, and to have consented to, the foregoing provisions of our
certificate of incorporation.

     Limitations on Directors' Liability

     Our certificate of incorporation provides that no director will be liable
to us or our stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability

     - for any breach of the director's duty of loyalty to us or our
       stockholders;

     - for acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

     - in respect of certain unlawful dividend payments or stock redemptions or
       repurchases; or

                                       73
<PAGE>   78

     - for any transaction from which the director derived an improper personal
       benefit.

     The effect of these provisions will be to eliminate our rights and our
stockholders' rights, through stockholders' derivative suits on our behalf, to
recover monetary damages against a director for breach of fiduciary duty as a
director, including breaches resulting from grossly negligent behavior, except
in the situations described above.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is ChaseMellon
Shareholder Services LLC.

                         UNITED STATES TAX CONSEQUENCES
                          TO NON-UNITED STATES HOLDERS

     The following discussion is a summary of the material United States federal
income and estate tax consequences of the ownership and disposition of our
common stock to Non-United States holders. This discussion does not deal with
all aspects of United States income and estate taxation and does not deal with
foreign, state and local tax consequences that may be relevant to Non-United
States holders in light of their personal circumstances. Furthermore, this
discussion is based on the Internal Revenue Code of 1986, as amended, Treasury
Department regulations, published positions of the Internal Revenue Service and
court decisions now in effect, all of which are subject to change. YOU SHOULD
CONSULT YOUR OWN TAX ADVISOR WITH REGARD TO THE APPLICATION OF THE FEDERAL
INCOME TAX LAWS, AS WELL AS TO THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL
OR FOREIGN TAX LAWS TO WHICH YOU MAY BE SUBJECT.

     As used in this section, a "United States holder" means a beneficial owner
of stock that is:

     - a citizen or resident of the United States;

     - a corporation or partnership created or organized in or under the laws of
       the United States or any political subdivision of the United States;

     - an estate the income of which is subject to United States federal income
       taxation regardless of its source;

     - a trust that:

        - is subject to the supervision of a court within the United States and
          the control of one or more United States persons; or

        - has a valid election in effect under applicable United States Treasury
          regulations to be treated as a United States person.

     A "Non-United States holder" is a holder that is not a United States
holder.

DIVIDENDS

     Generally, any dividend paid to a Non-United States holder will be subject
to United States withholding tax either at a rate of 30% of the gross amount of
the dividend or at a lesser applicable treaty rate. However, dividends that are
effectively connected with the conduct of a trade or business within the United
States and, where a tax treaty applies, that are attributable to a United States
permanent establishment are not subject to the withholding tax but instead are
subject to United States federal income tax on a net income basis at applicable
graduated individual or corporate rates.

     Certain certification and disclosure requirements must be complied with in
order to be exempt from withholding under the effectively connected income
exemption. Any effectively connected dividends received by a foreign corporation
may, under certain circumstances, be subject to an additional "branch profits
tax" at a 30% rate or a lower rate as may be specified by an applicable income
tax treaty.

     Until January 1, 2001, dividends paid to an address outside the United
States are presumed to be paid to a resident of that country, unless the payer
has knowledge to the

                                       75
<PAGE>   80

contrary, for purposes of the withholding tax discussed above and, under the
current interpretation of the United States treasury regulations, for purposes
of determining the applicability of a tax treaty rate. However, under United
States treasury regulations, if you wish to claim the benefit of an applicable
treaty rate and avoid backup withholding, as discussed below, for dividends paid
after December 31, 2000, you will be required to satisfy applicable
certification and other requirements.

     If you are eligible for a reduced treaty rate of United States withholding
tax pursuant to an income tax treaty, you may obtain a refund of any excess
amounts withheld by filing an appropriate claim for refund with the Internal
Revenue Service.

GAIN ON DISPOSITION OF COMMON STOCK

     If you are a Non-United States holder, you will generally not be subject to
United States federal income tax with respect to gain recognized on a sale or
other disposition of our common stock unless:

     - the gain is effectively connected with a trade or business in the United
       States and, where a tax treaty provides, the gain is attributable to a
       United States permanent establishment;

     - if you are an individual and hold our common stock as a capital asset,
       you are present in the United States for 183 or more days in the taxable
       year of the sale or other disposition and certain other conditions are
       met; or

     - we are or have been a "United States real property holding corporation"
       for United States federal income tax purposes.

     We believe that we are not, and do not anticipate becoming, a "United
States real property holding corporation" for United States federal income tax
purposes. If we were to become a United States real property holding
corporation, so long as our common stock continues to be regularly traded on an
established securities market, you would be subject to federal income tax on any
gain from the sale or other disposition of the stock only if you actually or
constructively owned, during the five-year period preceding the disposition,
more than 5% of our common stock.

     Special rules may apply to certain Non-United States holders, such as
"controlled foreign corporations," "passive foreign investment companies" and
"foreign personal holding companies," that are subject to special treatment
under the Code. These entities should consult their own tax advisors to
determine the United States federal, state, local and other tax consequences
that may be relevant to them.

BACKUP WITHHOLDING AND INFORMATION REPORTING

     We must report annually to the Internal Revenue Service and to you the
amount of dividends paid to you and the tax withheld with respect to these
dividends, regardless of whether withholding was required. Copies of the
information returns reporting the dividends and withholding may also be made
available to the tax authorities in the country in which you reside under the
provisions of an applicable income tax treaty.

     Under current law, backup withholding at the rate of 31% generally will not
apply to dividends paid to you at an address outside the United States, unless
the payer has knowledge that you are a United States person. Under the final
regulations effective

                                       76
<PAGE>   81

December 31, 2000, however, you will be subject to backup withholding unless
applicable certification requirements are met.

     Payment of the proceeds of a sale of our common stock within the United
States or conducted through certain U.S. related financial intermediaries is
subject to both backup withholding and information reporting unless you certify
under penalties of perjury that you are a Non-U.S. Holder, and the payor does
not have actual knowledge that you are a United States person, or you otherwise
establish an exemption.

     Any amounts withheld under the backup withholding rules may be allowed as a
refund or a credit against your United States federal income tax liability
provided the required information is furnished to the Internal Revenue Service.

ESTATE TAX

     Common stock held by an individual Non-United States holder at the time of
death will be included in that holder's gross estate for United States federal
estate tax purposes, unless an applicable estate tax treaty provides otherwise.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Prior to this offering, there has been no public market for our common
stock, and any sale of substantial amounts of common stock in the open market
may adversely affect the market price of our common stock. Furthermore, since
only a limited number of shares will be available for sale shortly after this
offering because of contractual and legal restrictions on resale, as described
below, sales of substantial amounts of our common stock in the public market
after the restrictions lapse could adversely affect the prevailing market price
and our ability to raise equity capital in the future.


     Upon completion of this offering, we will have 79,437,902 shares of common
stock outstanding. Of the shares of common stock to be outstanding, the
8,500,000 shares offered hereby will be available for immediate sale in the
public market as of the date of this prospectus, except that any shares acquired
by our "affiliates," as that term is defined in Rule 144 under the Securities
Act, generally may be resold in the public market only in compliance with the
provisions of Rule 144 other than the holding period required by Rule 144.



     All the remaining 70,937,902 shares of common stock to be outstanding will
be issued to Spencer Trask and to General Instrument in private transactions as
part of our recapitalization. Accordingly, all of these shares, as well as the
8,480,102 shares of common stock issuable upon the exercise of warrants held by
affiliates of Spencer Trask, will be "restricted securities," as that term is
defined in Rule 144. As such, these shares generally may be resold in the public
market only if registered under the Securities Act or sold in compliance with
the provisions of Rule 144, including the one-year holding period required by
Rule 144. Following the expiration of the one-year holding period, all of these
shares will be available for sale in the public market, subject to compliance
with the other provisions of Rule 144. In addition, General Instrument and
Spencer Trask will be entitled to registration rights pursuant to which they may
require that we register their shares under the Securities Act for sale in the
public market prior to or following the expiration of the one-year holding
period under Rule 144. For more information on these registration rights, see
"Certain Relationships and Related Transactions -- Registration Rights
Agreements."


     In addition to the legal restrictions on resale described above, each of
General Instrument and Spencer Trask has entered into a lockup agreement with
the underwriters pursuant to which they have agreed generally not to transfer or
dispose of shares of common stock or securities convertible into common stock
for a period of 180 days after the date of this prospectus. However, these
lockups may be waived on behalf of the underwriters by Credit Suisse First
Boston Corporation. For more information on these lockup agreements and those
described below, see "Underwriting -- No Sales of Similar Securities."

STOCK OPTIONS


     We have outstanding employee stock options to purchase 12,358,758 shares of
common stock. Immediately following the completion of this offering, options
covering 5,728,160 shares will have vested and become exercisable. The holders
of options to purchase 3,074,794 shares (of which options to purchase 2,692,140
shares will have vested upon completion of this offering) have entered into
365-day lockup agreements with the underwriters, and the holders of the
remaining options to purchase 9,283,964 shares (of which options to purchase
3,036,020 shares will have vested upon completion of this


                                       78
<PAGE>   83

offering) have entered into 180-day lockup agreements. Following completion of
this offering, we intend to file with the SEC a registration statement covering
the shares issuable upon the exercise of our outstanding employee options as
well as shares reserved for issuance under our employee stock option and stock
purchase plans. Accordingly, subject to vesting provisions and, in the case of
affiliates, the provisions of Rule 144 other than the holding period, the shares
of common stock issuable upon the exercise of our outstanding employee options
will be eligible for sale into the public market after the expiration of the
lockups. The lockups may be waived on behalf of the underwriters by Credit
Suisse First Boston Corporation.

RULE 144

     In general, under Rule 144 as currently in effect, a person who has
beneficially owned shares of our common stock for at least one year would be
entitled to sell, within any three-month period, a number of shares that does
not exceed the greater of:

     - 1% of the number of shares of common stock then outstanding; or

     - the average weekly trading volume of the common stock on the Nasdaq
       National Market System during the four calendar weeks preceding the
       filing of a notice on Form 144 with respect to the sale.

     Sales under Rule 144 are also subject to other requirements regarding the
manner of sale, notice filing and the availability of current public information
about us.

     Under Rule 144(k), a person who is not deemed to have been our affiliate at
any time during the 90 days preceding a sale, and who has beneficially owned the
shares proposed to be sold for at least two years, would be entitled to sell
these shares under Rule 144(k) without regard to the requirements described
above.

</TABLE>

     In the underwriting agreement, the several underwriters have agreed to
purchase all of the shares of our common stock being sold under the terms of the
agreement if any of the shares of common stock are purchased, other than those
shares covered by the over-allotment option described below. Under the
underwriting agreement, if an underwriter defaults, the commitments of
non-defaulting underwriters may be increased or the offering may be terminated.

     We have agreed to indemnify the underwriters against liabilities under the
Securities Act, or to contribute to payments the underwriters may be required to
make in respect of those liabilities.

     The shares of common stock are being offered by the several underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to approval of legal matters by counsel for the underwriters and other
conditions. The underwriters reserve the right to withdraw, cancel or modify
such offer and to reject orders in whole or in part.

     Lehman Brothers Inc., one of the representatives of the underwriters,
recently served as financial advisor to us and received a customary fee from us
for its services.

COMMISSIONS AND DISCOUNTS

     The representatives have advised us that the underwriters propose initially
to offer the shares of our common stock to the public at the initial public
offering price set forth on the cover page of this prospectus, and to dealers at
such price less a concession not in excess of $     per share of common stock.
The underwriters may allow, and such dealers may allow, a discount not in excess
of $     per share of common stock to other dealers.

                                       80

After the initial public offering, the public offering price and the concession
and discount may be changed.

     The following table summarizes the compensation and expenses we will pay
with respect to the shares to be issued under the underwriting agreement. This
information is presented assuming either no exercise or full exercise by the
underwriters of their over-allotment options.

     The expenses of this offering, exclusive of the underwriting discount, are
estimated at $2.8 million and are payable by us.

OVER-ALLOTMENT OPTION

     We have granted an option to the underwriters, exercisable for 30 days
after the date of this prospectus, to purchase up to an aggregate of an
additional 1,275,000 shares of our common stock at the initial public offering
price set forth on the cover of this prospectus, less the underwriting discount.
The underwriters may exercise this option solely to cover over-allotments, if
any, made on the sale of our common stock offered hereby. To the extent that the
underwriters exercise this option, each underwriter will be obligated to
purchase a number of additional shares of our common stock proportionate to such
underwriter's initial amount reflected in the foregoing table.

RESERVED SHARES


     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to 925,000 of the shares offered hereby to be sold to
some of our employees, management, directors and other persons with
relationships with us. The number of shares of our common stock available for
sale to the general public will be reduced to the extent that those persons
purchase the reserved shares. Any reserved shares not so purchased will be
offered to the general public on the same terms as the other shares.


NO SALES OF SIMILAR SECURITIES

     We, our executive officers and directors and all of our stockholders and
optionholders have agreed that we and they will not offer, sell, contract to
sell, pledge or otherwise dispose of, directly or indirectly, or file with the
Securities and Exchange Commission a registration statement under the Securities
Act relating to any shares of our common stock or securities convertible into or
exchangeable or exercisable for any of our common stock, or publicly disclose
the intention to make any such offer, sale, pledge, disposition or filing,
without the prior written consent of Credit Suisse First Boston Corporation for
a period of 180 days (or, in the case of Peter W. Keeler and Thomas R. Eames,
365 days) after the date of this prospectus, except, in our case, issuances in
connection with this offering or our recapitalization or pursuant to our
employee stock option and stock purchase plans.

DETERMINATION OF OFFERING PRICE; QUALIFIED INDEPENDENT UNDERWRITER

     Before this offering, there has been no market for our common stock. The
initial public offering price will be determined through negotiations between us
and the representatives of the underwriters. The factors to be considered in
determining the initial public offering price, in addition to prevailing market
conditions, include the valuation multiples of publicly traded companies that
the representatives believe to be comparable to us, some of our financial
information, the history of, and the prospects for, us and the industry in which
we compete, and an assessment of our management, its past and present
operations, the prospects for, and timing of, our future revenues, the present
state of our development, the percentage interest of us being sold as compared
to our valuation and the above factors in relation to market values and various
valuation measures of other companies engaged in activities similar to ours.
There can be no assurance that an active trading market will develop for our
common stock or that our common stock will trade in the public market subsequent
to this offering at or above the initial public offering price.

     This offering is being conducted in accordance with the applicable
provisions of Rule 2720 of the National Association of Securities Dealers, Inc.
Conduct Rules because Spencer Trask Securities, Inc., one of the selling group
members, is an affiliate of Spencer Trask Investments LLC, which beneficially
owns 10% or more of our common stock. Rule 2720 requires that the initial public
offering price of the shares of common stock not be higher than that recommended
by a "qualified independent underwriter" meeting certain standards. Accordingly,
Credit Suisse First Boston Corporation is assuming the responsibilities of
acting as the qualified independent underwriter in pricing the offering and
conducting due diligence. The initial public offering price of the shares of
common stock will be no higher than the price recommended by Credit Suisse First
Boston Corporation.

NASDAQ NATIONAL MARKET LISTING


     Our common stock has been approved for listing on the Nasdaq National
Market under the symbol "NXTV."


SALES TO DISCRETIONARY ACCOUNTS

     The underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.

PRICE STABILIZATION AND SHORT POSITIONS

     Until the distribution of our common stock is completed, rules of the SEC
may limit the ability of the underwriters and selling group members to bid for
and purchase our common stock. As an exception to these rules, the underwriters
are permitted to engage in transactions that stabilize the price of our common
stock. Such transactions consist of bids or purchases for the purpose of
pegging, fixing or maintaining the price of our common stock.

     If the underwriters create a short position in our common stock in
connection with this offering, i.e., if they sell more shares of our common
stock than are set forth on the cover page of this prospectus, the underwriters
may reduce that short position by purchasing our common stock in the open
market. The underwriters may also elect to

                                       82
<PAGE>   87

reduce any short position by exercising all or part of the over-allotment option
described above.

PENALTY BIDS

     The underwriters may also impose a penalty bid on other underwriters and
selling group members. This means that if the underwriters purchase shares of
our common stock in the open market to reduce their short position or to
stabilize the price of our common stock, they may reclaim the amount of the
selling concession from the underwriters and selling group members who sold
those shares as part of this offering.

     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of our common stock to the extent that it
discourages resales of our common stock.

     Neither we nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of our common stock. In addition, neither
we nor any of the underwriters makes any representation that the representatives
will engage in such transactions or that such transactions, once commenced, will
not be discontinued without notice.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are effected. Accordingly, any resale of the common stock
in Canada must be made in accordance with applicable securities laws. These will
vary depending on the relevant jurisdiction and may require resales to be made
in accordance with available statutory exemptions or under a discretionary
exemption granted by the applicable Canadian securities regulatory authority.
Purchasers are advised to seek legal advice before any resale of the common
stock.

REPRESENTATIONS OF PURCHASERS

     Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom the
purchase confirmation is received that: (i) the purchaser is entitled under
applicable provincial securities laws to purchase the common stock without the
benefit of a prospectus qualified under such securities laws; (ii) where
required by law, the purchaser is purchasing as principal and not as agent; and
(iii) the purchaser has reviewed the text above under "Resale Restrictions."

RIGHTS OF ACTION (ONTARIO PURCHASERS)

     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

ENFORCEMENT OF LEGAL RIGHTS

     All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Canadian purchasers to effect service of process within Canada upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against the issuer or these persons in Canada
or to enforce a judgment obtained in Canadian courts against such issuer or
persons outside of Canada.

NOTICE TO BRITISH COLUMBIA RESIDENTS

     A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that the purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by the purchaser in this offering. This report must be in
the form attached to British Columbia Securities Commission Blanket Order BOR
#95/17, a copy of which may be obtained from us. Only one report must be filed
in respect of common stock acquired on the same date and under the same
prospectus exemption.

                          INDEPENDENT AUDITORS' REPORT

Next Level Communications L.P.:

     We have audited the accompanying balance sheets of Next Level
Communications L.P. (formerly Next Level Communications) as of December 31, 1997
and 1998 and September 30, 1999 and the related statements of operations,
partners' deficit/stockholder's deficit and cash flows for each of the three
years in the period ended December 31, 1998 and for the nine months ended
September 30, 1999. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, such financial statements present fairly, in all material
respects, the financial position of Next Level Communications L.P. as of
December 31, 1997 and 1998 and September 30, 1999 and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1998 and for the nine months ended September 30, 1999 in conformity
with generally accepted accounting principles.

     As discussed in Note 2, Next Level Communications L.P. has incurred
operating losses and negative cash flows and is dependent upon obtaining
additional capital to fund its operations and meet its obligations.

                         NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION AND BUSINESS

     Next Level Communications L.P. (the "Partnership") is a leading provider of
broadband communications systems that enable telephone companies and other
emerging communications service providers to cost effectively deliver voice,
data and video services over the existing copper wire telephone infrastructure.

     Next Level Communications ("NLC" or the "Limited Partner") was incorporated
as a California corporation on June 22, 1994 and commenced operations in July
1994. In September 1995, NLC was acquired by General Instrument Corporation
("General Instrument").

     In January 1998, NLC transferred its net assets, management and workforce
to a newly formed limited partnership, Next Level Communications L.P., in
exchange for an 89% limited partnership interest. The Partnership recorded the
net assets transferred at their historical cost. At the same time, Spencer Trask
(the "General Partner") acquired an 11% general partner interest in the
Partnership in exchange for a $10.0 million cash contribution.

     Net losses have been allocated to the partners based on their respective
partnership percentages. Upon the Partnership's conversion to a corporation (the
"Successor Corporation") in conjunction with an initial public offering, each
partner will receive voting common stock of the Successor Corporation based on
their respective partnership percentages. The General Partner has an option,
which expires on January 13, 2003, to acquire from the Limited Partner, up to
11% of the Successor Corporation common stock. This option is exercisable after
an IPO or in connection with a merger or sale of the Successor Corporation. Upon
dissolution of the Partnership, the assets would be used to pay all liabilities
of the Partnership and any remaining assets, after establishment of reserves,
would be distributed to the partners in accordance with their respective
partnership percentages.

     On August 24, 1999 the Partnership formed a wholly owned subsidiary, Next
Level Communications, Inc., a Delaware corporation.

     In anticipation of the Recapitalization (see note 3), management of NLC
effected a 1-for-3 reverse stock split on October 14, 1999. All share amounts in
the accompanying financial statements have been restated to give effect to the
reverse stock split.

     The accompanying financial statements represent those of the Partnership
for 1998 and the nine months ended September 30, 1998 (unaudited) and 1999 and
those of NLC for 1997 and 1996. The results of operations for the nine months
ended September 30, 1999 are not necessarily indicative of the results expected
for the full year.

2. RESULTS OF OPERATIONS FOR 1999, 1998, 1997 AND 1996 AND MANAGEMENT PLANS FOR
2000 AND 1999

     The Partnership incurred net losses of $59.9 million, $81.7 million, $66.4
million, and $173.9 million in the nine months ended September 30, 1999 and the
fiscal years ended December 31, 1998, 1997 and 1996, respectively, as a result
of substantial research and

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

development expenditures and litigation expenses. Net cash used in operating
activities was $44.4 million, $66.6 million, $208.5 million and $33.0 million in
the nine months ended September 30, 1999 and the fiscal years ended December 31,
1998, 1997 and 1996, respectively. At September 30, 1999, partners' deficit was
$40.7 million.

     The Partnership has prepared cash flow projections for 1999 that indicate
additional capital will be required during the latter part of 1999 to fund its
operations and meet its obligations. The Partnership believes that it has
several alternatives available to it to obtain the required capital, including
additional equity contributions from its partners, private placement financing
and/or an IPO. Management of the Partnership believes that cash and cash
equivalents at September 30, 1999 and additional capital from the sources noted
above will enable the Partnership to fund its operations and meet its
obligations through at least September 30, 2000.

3. SIGNIFICANT ACCOUNTING POLICIES

     USE OF ESTIMATES -- The preparation of the accompanying financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenue and
expenses during the year. Actual results could differ from those estimates.

     INTERIM FINANCIAL INFORMATION (UNAUDITED) -- The financial statements for
the nine months ended September 30, 1998 are unaudited, and in the opinion of
management, contain all adjustments that are of a normal and recurring nature
necessary to present fairly the financial position and results of operations for
such period.

     PRO FORMA INFORMATION (UNAUDITED) -- The unaudited pro forma balance sheet
as of September 30, 1999 presents the Partnership's balance sheet as if the
following (the "Recapitalization") had occurred on September 30, 1999:

     (i)  the $75.0 million note and accrued interest thereon payable to General
          Instrument was contributed by General Instrument to Next Level
          Communications, Inc., a newly formed Delaware corporation ("NLC
          Delaware"); and

     (ii)  the Partnership and NLC were merged into NLC Delaware.


     (iii) in conjunction with the transactions described in (i) and (ii) above
           and based upon an assumed initial public offering price of $18.00 per
           share, the General Partner received 5,863,329 shares of common stock
           and the Limited Partner received 65,029,980 shares of common stock.


     Pro forma basic and diluted net loss per share, discussed below, is
computed by dividing the pro forma net loss by the pro forma shares outstanding
for the period giving effect to the Recapitalization as if it had occurred on
January 1, 1998. The pro forma shares outstanding exclude warrants held by
affiliates of the General Partner to purchase approximately 8,480,102 shares of
common stock, employee stock options to purchase 6,964,904 shares of common
stock as of September 30, 1999 and options to purchase

                         NEXT LEVEL COMMUNICATIONS L.P.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)


5,393,854 shares of common stock granted in October and November 1999. Shares
under these options and warrants were not included in the computation of pro
forma diluted net loss per common share since the inclusion of these shares
would be antidilutive.



     Pro forma basic and diluted net loss per share of $1.07 and $0.77 for the
year ended December 31, 1998 and the nine months ended September 30, 1999,
respectively, give effect to the contribution of the note and accrued interest
thereon payable to General Instrument and the related elimination of interest
expense of $5.9 million and $5.0 million for the year ended December 31, 1998
and the nine months ended September 30, 1999, respectively. Pro forma shares
outstanding were 70,893,309 for the pro forma periods presented.


     REVENUE RECOGNITION -- The Partnership recognizes revenue from equipment
sales when the product has been shipped. Sales contracts do not permit the right
of return of product by the customer. Amounts received in excess of revenue
recognized are recorded as deferred revenue. As of September 30, 1999 deferred
revenue primarily relates to advance payments received on equipment sales.

     Software license revenues are recognized when software revenue recognition
criteria have been met, pursuant to Statement of Position ("SOP") 97-2, Software
Revenue Recognition. Under SOP 97-2, license revenue is recognized when a
noncancelable license agreement has been signed, delivery has occurred, the fees
are fixed and determinable and collection is probable. The portion of revenues
from new license agreements which relate to the Partnership's obligations to
provide customer support are deferred, based upon the price charged for customer
support when it is sold separately, and recognized ratably over the maintenance
period.

     PRODUCT WARRANTY -- The Partnership provides for the estimated costs to
fulfill customer warranty obligations upon the recognition of the related
equipment revenue. Actual warranty costs incurred are charged against the
accrual when paid.

     CASH EQUIVALENTS -- The Partnership considers all highly liquid debt
instruments with a maturity of three months or less at the date of purchase to
be cash equivalents.

     INVENTORIES -- Inventories are stated at the lower of cost, determined on a
first-in, first-out basis, or market.

     PROPERTY AND EQUIPMENT -- Property and equipment are stated at cost.
Provisions for depreciation are based on estimated useful lives of the assets
using the straight-line method. Useful lives range from the shorter of five to
ten years or the lease term for leasehold improvements and two to seven years
for machinery and equipment.

     INTANGIBLE ASSETS -- Intangible assets consist principally of goodwill,
which is being amortized on a straight-line basis over seven years. Management
continually reassesses the appropriateness of both the carrying value and
remaining life of the intangible assets by assessing recoverability based on
forecasted operating cash flows, on an undiscounted basis, and other factors.
Management believes that the carrying value and remaining lives of these assets
are appropriate.

                                       F-9

                         NEXT LEVEL COMMUNICATIONS L.P.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     LONG-LIVED ASSETS -- Whenever events indicate that the carrying values of
long-lived assets or identifiable intangibles may not be recoverable, the
Partnership evaluates the carrying values of such assets using future
undiscounted cash flows. If the sum of the expected undiscounted future cash
flows is less than the carrying amount of the asset, the Partnership will
recognize an impairment loss equal to the difference between the fair value and
carrying value of such asset.

     OTHER INCOME (EXPENSE), NET -- Other income (expense), net consists
primarily of interest income.

     INCOME TAXES -- Income taxes are not included in the 1998 or 1999 financial
statements since income taxes on the Partnership's income are the responsibility
of the partners.

     For the years ended December 31, 1996 and 1997, NLC accounted for income
taxes using the asset and liability method. Deferred income taxes reflect the
future tax consequences of differences between the financial reporting and tax
basis of assets and liabilities. The accompanying financial statements for 1996
and 1997 present NLC's income taxes on a separate company basis. In 1996 and
1997, the results of NLC were included in the consolidated tax returns of
General Instrument, and NLC's net operating losses were utilized by General
Instrument in its tax returns. A valuation allowance is provided when it is more
likely than not that some portion of the deferred tax asset will not be
realized. At December 31, 1997, and 1996 there was a 100% valuation allowance
provided for these deferred tax assets due to the uncertainty of realizing
future tax benefits from these deferred tax assets on a stand-alone NLC basis.

     At December 31, 1997, NLC had no amounts due to or from General Instrument
related to income taxes. For the years ended December 31, 1996 and 1997, there
was no current or deferred tax expense or benefit recorded by NLC.

     FAIR VALUE OF FINANCIAL INSTRUMENTS -- The carrying amounts of cash and
cash equivalents, accounts receivable and accounts payable approximate fair
value because of the short-term nature of these instruments. The fair value of
long-term debt is based upon current interest rates for debt instruments with
comparable maturities and characteristics.

     COMPREHENSIVE INCOME -- Statement of Financial Accounting Standards
("SFAS") No. 130, Reporting Comprehensive Income, requires that all items
recognized under accounting standards as components of comprehensive income be
reported in an annual financial statement that is displayed with the same
prominence as other annual financial statements. There were no items of other
comprehensive income (loss) and therefore comprehensive loss was the same as net
loss for all periods presented.

     SEGMENT REPORTING -- SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information establishes standards for the reporting of
information about operating segments, including related disclosures about
products and services, geographic areas and major customers, and requires
selected information about operating segments in interim financial statements.
The Partnership operates in only one reportable segment and one geographic area
and therefore additional information is not required to be presented. For the
nine months ended September 30, 1999, revenues attributable to the Partnership's

                                      F-10
<PAGE>   101

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

two largest customers were 61% and 14%, respectively, of total revenues. In 1998
these same customers accounted for 68% and 20%, respectively, of total revenues.
In 1997 these same customers accounted for 17% and 55%, respectively, of total
revenues.

     CERTAIN SIGNIFICANT RISKS AND UNCERTAINTIES -- Two customers comprised
substantially all of the Partnership's revenue from equipment sales in 1997 and
1998. As of September 30, 1999 and December 31, 1998, 80% and 84%, respectively,
of the Partnership's trade accounts receivable were derived from these two
customers. The loss of either of these customers or any substantial reduction in
orders by either of these customers could have a material adverse affect on the
Partnership's operating results. Additionally, the Partnership relies on certain
contract manufacturers to perform substantially all of its manufacturing
activities. The inability of its contract manufacturers to fulfill their
obligations to the Partnership could adversely impact future results.

     The Partnership performs ongoing credit evaluations of its customers and
generally does not require collateral from its customers. The Partnership
maintains allowances for potential losses, and has not incurred any significant
losses to date. Allowance for doubtful accounts activity consisted of (in
thousands):

4. ACQUISITION OF TELENETWORKS

     In September 1997, General Instrument acquired all of the outstanding
capital stock of Telenetworks, a specialized data protocol communications
software company. The purchase price was approximately $7.0 million in cash. The
acquisition was accounted for using the purchase method of accounting and,
accordingly, the assets acquired and liabilities assumed were recorded at their
estimated fair values as of the date of acquisition. The $6.9 million excess of
the purchase price over the net identifiable assets acquired was allocated to
goodwill. In January 1998, in conjunction with the formation of the Partnership,
the Limited Partner contributed the assets and liabilities of Telenetworks to
the Partnership at its cost. For financial statement purposes, Telenetworks'
assets, liabilities and results of operations have been included in the
accompanying financial statements since September 1, 1997.

                         NEXT LEVEL COMMUNICATIONS L.P.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     In conjunction with the acquisition in September 1997, General Instrument
granted approximately 358,000 shares of restricted common stock of General
Instrument valued at $7.0 million in total to certain Telenetworks employees.
The restricted shares were valued at the quoted market price of $19.56 per share
of General Instrument's common stock at the date of grant. The restrictions on
the common stock of General Instrument lapsed over a 270-day period which ended
on May 31, 1998. Since this common stock was payable based solely on the
continued employment of the individuals, prepaid compensation of $7.0 million
was recorded and amortized to compensation expense over the life of the
restrictions. Compensation expense of $3.9 million and $3.1 million was recorded
in 1998 and 1997.

     In June 1998, the Partnership issued approximately $2.9 million in loans to
former Telenetworks employees due to certain tax liabilities associated with the
restricted stock, $2.5 million of which was outstanding at December 31, 1998 and
recorded in other receivables. The loans were due in April 1999, and were
collateralized by the common stock of General Instrument held by such employees.
As of September 30, 1999 such loans were fully repaid.

8. RELATED PARTY TRANSACTIONS WITH GENERAL INSTRUMENT

     In January 1998, in conjunction with the formation of the Partnership,
General Instrument advanced $75.0 million to the Partnership in exchange for a
note (the "Note") bearing interest at a rate of 8%. The Note includes certain
covenants including limitations on borrowings, and is due in 2005. The Note
provides for the deferral of scheduled interest payments under certain
circumstances. Deferred interest payments bear interest at 10% and are not
payable until certain earnings levels, as defined, are met. The Partnership or
the Successor Corporation has an option, upon an IPO of the Successor
Corporation, to repay the Note, together with accrued interest, in shares of
stock of the Successor Corporation. At December 31, 1998, the Partnership owed
General Instrument $80.9 million under this Note, including accrued interest of
$5.9 million. The fair value of the Note, computed based upon current interest
rates for debt instruments with comparable maturities and characteristics, as at
December 31, 1998 was approximately $62.5 million. At September 30, 1999, the
Partnership owed General Instrument $86.0 million under this note, including
accrued interest of $11.0 million.

     At December 31, 1997 NLC had a payable to General Instrument of $41.1
million representing net advances to it during 1997. This amount was contributed
to the Partnership in 1998. During 1998, an additional $19.6 million was
contributed to the Partnership by the Limited Partner.

     In 1999, the Limited Partner provided an additional $34.0 million of
capital contributions and increased its Partnership interest to 90.4%.

     In 1996 and 1997, General Instrument allocated the cost of certain
corporate general and administrative services and shared services (primarily
certain legal and other costs related to the litigation discussed in Note 12) to
NLC. Such allocations were based upon General Instrument's estimates of the
incremental costs of providing such services. Management believes that the
method used by General Instrument to determine the allocated expenses was
reasonable. The allocated expenses were $3.0 million and $1.0 million in 1996
and 1997, respectively. It is not practicable to determine the actual costs that
would have been incurred if NLC operated on a stand-alone basis; accordingly
such allocations may not necessarily be indicative of the level of expenses
which would have been incurred had it been operating as a separate stand-alone
entity through December 31, 1997. Since January 1, 1998, all costs to operate on
a stand-alone basis were incurred by the Partnership and have been reflected in
the accompanying financial statements. Accordingly, no costs were allocated to
the Partnership during such periods.

9. STOCK OPTION PLANS

     Certain employees of the Partnership have been granted contingently
exercisable stock options (included in the table which follows) in NLC which
vest over a period of two to three years and which expire in ten years. Such
options are exercisable only in the event of an IPO or a change in control of
NLC (the "Event"). Compensation expense will be recognized on the date of the
Event based on the difference between the exercise price of the options and the
fair value of the common stock of a successor corporation on the date of the
Event. Management believes that the compensation expense will be material.

     In addition, in January 1997, as part of a tandem stock option grant,
certain employees of NLC were granted options at $1.11 per share for a total of
1.9 million shares of common stock of NLC, or options at $15.75 per share for a
total of 1.5 million shares of General Instrument common stock (the "GI
Options"). Under the terms of the grant, the exercise of options on either NLC
or General Instrument common stock results in the cancellation of options in the
other company's common stock at a ratio of approximately 1.4 shares of NLC
common stock to 1 share of General Instrument common stock. The NLC options are
exercisable only upon the Event. The options have a ten-year life and vest over
three years. If the GI options are more likely to be exercised no compensation
expense will be recognized. If it becomes more likely that the NLC options will
be exercised, compensation expense will be recognized at such time, based upon
the difference between the exercise price of the NLC options and the fair market
value of the NLC common stock on the date of the Event. Management believes that
such compensation expense, if the NLC options are more likely to be exercised,
will be material.

     The following table summarizes stock option activity relating to NLC's
stock option plan (including those granted as part of the tandem stock option
grant):

     Stock-based awards granted to employees are accounted for using the
intrinsic value method in accordance with Accounting Principles Board Opinion
("APB") No. 25, Accounting for Stock Issued to Employees. SFAS No. 123,
Accounting For Stock Based Compensation, requires the disclosure of pro forma
net income (loss) using the fair value method.

     The estimated fair value of an option grant is based, in part, on the
estimated term of the option. NLC options granted under the NLC Plan are not
exercisable unless an Event occurs. As a result, it is not practicable to
determine the expected term of NLC options and therefore it is not possible to
estimate the fair value of such options. The weighted average fair value of the
GI options granted during 1997 was $5.70.

     Had compensation cost been determined under SFAS 123 for the GI Options
under the tandem stock option grant, the Partnership's net loss would have been
changed to the pro forma amounts indicated below (in thousands):

10. EMPLOYEE BENEFIT PLANS

     Employees of the Partnership, who meet certain eligibility requirements are
able to participate in the General Instrument 401(k) Plan. Employees may
contribute up to 10% of their annual compensation, subject to the legal maximum.
The Partnership, contributes an amount equal to 50% of the first 6% of the
employee's salary that the employee contributes. The Partnership's expense
related to the 401(k) Plan was $430,000, $513,000, $409,000 and $213,000 for the
nine months ended September 30, 1999 and the years ended December 31, 1998, 1997
and 1996, respectively.

     The Partnership employees participate in the General Instrument Pension
Plan. The Partnership expensed $360,000, $419,000, $229,000 and $210,000 related
to these plans for the nine months ended September 30, 1999 and the years ended
December 31, 1998, 1997 and 1996, respectively.

11. CAPITAL LEASE OBLIGATIONS

12. COMMITMENTS AND CONTINGENCIES

     The Partnership leases its facilities and certain equipment under operating
leases. Leases expire at various dates from 1999 to 2006 and certain facilities
leases have renewal options.

     During 1998 the Partnership entered into an operating lease for one of its
buildings which expires in 2004. The lease provides for a purchase option but
does not allow for renewal options. General Instrument has provided a residual
value guarantee to the lessor of approximately 82% of the total building cost at
inception. The table of future minimum operating lease payments below excludes
any payments related to the residual guarantee. Rent expense recorded under the
lease was $0.8 million in 1998 and $1.0 million in the nine months ended
September 30, 1999.

in 1998, and $3.2 million in the nine months ended September 30, 1999.

     The Partnership has a commitment with a supplier to purchase approximately
$2.1 million of components in the 12 months following the release of certain
products for sale and approximately $4.3 million in the subsequent 12 months. In
addition, the Partnership has a commitment to purchase $2.4 million of
components prior to September 2002 with a minimum purchase of $0.5 million each
12-month period following the release of the certain products for sale. The
Partnership has a commitment to another supplier to purchase approximately $14.7
million of components prior to December 2001.

     In May 1998, actions by BroadBand Technologies, Inc. against General
Instrument and by Next Level Communications against BroadBand Technologies,
pending in the United States District Court for the Eastern District of North
Carolina, were dismissed with prejudice. The action brought by BroadBand related
to fiber optic communications systems for delivering television signals and a
patent held by BroadBand. The action brought by Next Level Communications
involved contentions that BroadBand infringed two patents held by Next Level
Communications relating to video compression and signal processing and that
BroadBand had violated antitrust laws. These dismissals were entered pursuant to
a settlement agreement under which, among other things, Next Level
Communications L.P. paid BroadBand Technologies $5.0 million, which was expensed
in 1998, and BroadBand Technologies and Next Level Communications L.P. have
entered into a perpetual cross-license of patents applied for or issued
currently or through May 2003.

     In April 1995, DSC Communications Corporation and DSC Technologies
Corporation (collectively, "DSC") brought suit against NLC and the founders of
NLC. In June 1996, a final judgement against NLC and the individual defendants
was entered in favor of DSC, and an expense for the expected final award of
$141.0 million was recorded. General Instrument paid the $141.0 million
judgement in 1997 as required by the 1995 agreement for the acquisition of NLC;
accordingly, the $141.0 million has been shown as a capital contribution in
1997.

     On March 5, 1998, an action entitled DSC Communications Corporation and DSC
Technologies Corporation v. Next Level Communications, L.P., Spencer Trask
Investors LLC, General Instrument Corporation and Spencer Trask & Co., Inc. was
filed in the Superior Court of the State of Delaware in and for New Castle
County (the "Delaware Action"). In that action, DSC alleged that in connection

Partnership and the transfer of the switched digital video technology, the
Partnership and Spencer Trask Investors LLC misappropriated DSC's trade secrets;
that General Instrument improperly disclosed trade secrets when it conveyed such
technology to the Partnership; and that Spencer Trask conspired to
misappropriate DSC's trade secrets. The plaintiffs sought actual damages for the
defendants' purported unjust enrichment, disgorgement of consideration,
exemplary damages and attorney's fees, all in unspecified amounts. In April
1998, General Instrument and the other defendants filed an action in the United
District Court for the Eastern District of Texas, requesting that the federal
court preliminarily and permanently enjoin DSC from prosecuting the Delaware
Action because by pursuing such action, DSC effectively was trying to circumvent
and relitigate the Texas federal court's November 1997 judgment in a previous
lawsuit involving DSC. On May 14, 1998, the United States District Court for the
Eastern District of Texas granted a preliminary injunction preventing DSC from
proceeding with the Delaware Action. On July 6, 1998, the defendants filed a
motion for summary judgement with the Texas Court requesting a permanent
injunction preventing DSC from proceeding with this litigation. In June 1999 the
United States Court of Appeals for the Fifth Circuit affirmed the judgment of
the Texas court. On July 15, 1999, the Texas federal court granted the Delaware

                             NOTES TO BALANCE SHEET

1. ORGANIZATION AND BUSINESS PURPOSE

     Next Level Communications, Inc. (the "Company") is a wholly-owned
subsidiary of Next Level Communications L.P. The Company is a Delaware
corporation formed on August 24, 1999 for the purpose of merging with Next Level
Communications L.P. to effect an initial public offering (the "offering").

2. RECAPITALIZATION

     Immediately prior to the completion of this offering, the following
interdependent recapitalization transactions will occur:


     - the Next Level Communications L.P. $75.0 million note and accrued
       interest thereon payable to General Instrument will be contributed by
       General Instrument to Next Level Communications, Inc., in exchange for a
       number of shares of common stock equal to the aggregate amount owed under
       the note divided by the initial offering price (which would be 4,775,000
       shares based upon $86.0 million owed as of September 30, 1999 and an
       assumed initial offering price of $18.00 per share); and


     - Next Level Communications L.P. and Next Level Communications, a wholly
       owned subsidiary of General Instrument and the limited partner of Next
       Level Communications L.P., each will be merged into Next Level
       Communications, Inc. As part of these mergers:

        - Spencer Trask, the general partner of the partnership, will receive
          5,863,329 shares of common stock for its 9.6% general partnership
          interest;


        - General Instrument will receive a number of shares of common stock,
          for Next Level Communications' 90.4% limited partnership interest and
          other interests under the partnership agreement, equal to 55,366,091
          plus a number equal to $88.0 million divided by the initial offering
          price (which would be 4,888,889 shares based upon an assumed initial
          offering price of $18.00 per share). General Instrument will receive
          such additional $88.0 million of common stock as a result of the
          following:



             - The Next Level Communications L.P. partnership agreement
               contemplated that Next Level Communications L.P. would be
               converted into a corporation (the "Successor Corporation") in
               connection with an initial public offering. Under the partnership
               agreement, affiliates of Spencer Trask (the general partner),
               have an option to acquire from Next Level Communications (the
               limited partner), a wholly owned subsidiary of General
               Instrument, 11% of the Successor Corporation common stock to be
               issued in such conversion. By operation of the mergers
               contemplated herein, the option held by affiliates of Spencer
               Trask to purchase 11% of Next Level Communications, Inc. (the
               Successor Corporation) common stock from Next Level
               Communications will become warrants to purchase 11% of Next Level
               Communications, Inc. common stock from Next Level Communications,
               Inc. with the same terms;


                                      F-21
<PAGE>   112


             - Should the warrants be exercised by affiliates of Spencer Trask,
               Next Level Communications, Inc., rather than Next Level
               Communications, will receive $88.0 million. Therefore, General
               Instrument will receive $88.0 million of common stock upon the
               conversion of Next Level Communications L.P. into Next Level
               Communications, Inc. to make up for the exercise price, that
               would have been received by General Instrument (through Next
               Level Communications, the limited partner) upon exercise of the
               warrants by affiliates of Spencer Trask under the partnership
               agreement;


        - options granted to employees of the partnership to purchase shares of
          Next Level Communications will become options to purchase a total of
          6,964,904 shares of common stock on a one for one basis; and

        - the option currently held by affiliates of Spencer Trask to purchase
          shares of the partnership's successor under the partnership agreement
          will become warrants to purchase from the Company 8,480,102 shares of
          common stock at an exercise price of $10.38 per share.

     The recapitalization will be accounted for at historical cost.

3. EMPLOYEE STOCK PLANS

  1999 STOCK PLAN


     Our board of directors adopted our 1999 Stock Plan effective October 1,
1999. Our stockholder also approved this plan. We have reserved 6,000,000 shares
of our common stock for grants under the 1999 Stock Plan. If options or shares
awarded under the 1999 Stock Plan are forfeited, then those options or shares
will become available for new awards. We have granted options covering 5,393,854
shares of our common stock under the 1999 Stock Plan. These options have an
exercise price equal to $11.00 per share, and they will become exercisable with
respect to 25% of the shares after 12 months of service and the remaining 75% in
equal monthly installments over the next 36 months of service. We will make no
awards under the 1999 Stock Plan after this offering.


     Participants in the plan may include employees, consultants and members of
the board of directors who are not employees. The board may grant options to
purchase shares of our common stock, or it may grant restricted shares of our
common stock. Options may be incentive stock options, which may qualify for
favorable tax treatment and which have a minimum exercise price equal to 100% of
the fair market value of the underlying stock on the date of grant. Options may
also be nonstatutory stock options, which cannot qualify for favorable tax
treatment and which have a minimum exercise price equal to 85% of the fair
market value of the underlying stock on the date of grant. Options expire not
later than 10 years after the date of grant, and they expire earlier if the
optionee's service ends earlier.

  1999 EQUITY INCENTIVE PLAN

     Our board of directors adopted our 1999 Equity Incentive Plan on October
10, 1999. Our stockholder also approved this plan. We have reserved 4,000,000
shares of our common stock for issuance under the 1999 Equity Incentive Plan. In
addition, any shares reserved under the 1999 Stock Plan for options not granted
at the time of this offering will become available for grants under the 1999
Equity Incentive Plan. In general, if options or

                                      F-22
<PAGE>   113

shares awarded under the 1999 Stock Plan or the 1999 Equity Incentive Plan are
forfeited, then those options or shares will again become available for awards
under the 1999 Equity Incentive Plan. We have not yet granted any options under
the 1999 Equity Incentive Plan, and none will be granted until after this
offering.

     The exercise price of each non-employee director's option will be equal to
the fair market value of our common stock on the option grant date. Options
expire not later than 10 years after the date of grant.

     1999 EMPLOYEE STOCK PURCHASE PLAN

     Our board of directors adopted our 1999 Employee Stock Purchase Plan on
October 10, 1999. Our stockholder also approved this plan. Our 1999 Employee
Stock Purchase Plan is intended to qualify under Section 423 of the Internal
Revenue Code. We have reserved 1,000,000 shares of our common stock for issuance
under the plan. On November 1 of each year, starting with the year 2000, the
number of shares in the reserve will automatically be increased by 1,000,000
shares or 1% of the shares then outstanding, whichever is less.

     All of our employees are eligible to participate. Eligible employees may
begin participating in the 1999 Employee Stock Purchase Plan at the start of any
offering period. Each offering period lasts 24 months. Overlapping offering
periods start on May 1 and November 1 of each year. However, the first offering
period will start on the effective date of this offering and end on October 31,
2001.

     The price of each share of common stock purchased under our 1999 Employee
Stock Purchase Plan will be 85% of the lower of:

     - the fair market value per share of common stock on the date immediately
       before the first day of the applicable offering period; or

     - the fair market value per share of common stock on the purchase date;

     In the case of the first offering period, the price per share under the
plan will be 85% of the lower of:

     - the price per share to the public in this offering; or

     - the fair market value per share of common stock on the purchase date.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's Board of Directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). The Registrant's Certificate of Incorporation
provides for mandatory indemnification of its directors and officers and
permissible indemnification of employees and other agents to the maximum extent
permitted by the Delaware General Corporation Law. The Registrant's Certificate
of Incorporation provides that, pursuant to Delaware law, its directors shall
not be liable for monetary damages for breach of the directors' fiduciary duty
as directors to the Company and its stockholders. This provision in the
Certificate of Incorporation does not eliminate the directors' fiduciary duty,
and in appropriate circumstances equitable remedies such as injunctive or other
forms of non-monetary relief will remain available under Delaware law. In
addition, each director will continue to be subject to liability for breach of
the director's duty of loyalty to the Company for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
actions leading to improper personal benefit to the director, and for payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws. The Registrant has entered into
Indemnification Agreements with its officers and directors, a form of which is
attached as Exhibit 10.1 hereto and incorporated herein by reference. The
Indemnification Agreements provide the Registrant's officers and directors with
further indemnification to the maximum extent permitted by the Delaware General
Corporation Law." Reference is made to Section 6 of the Underwriting Agreement
contained in Exhibit 1.1 hereto, indemnifying officers and directors of the
Registrant against certain liabilities.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

     Within the last three years, a predecessor to the Registrant sold
securities in the following transactions, each of which was intended to be
exempt from the registration requirements of the Securities Act of 1933, as
amended.

     In January 1998, Next Level Communications, a subsidiary of General
Instrument, acquired an 89% limited partner interest in Next Level
Communications L.P. (the "Partnership") in exchange for the net assets,
management and workforce of Next Level Communications.

     In January 1998, General Instrument advanced $75.0 million to the
Partnership in exchange for a note convertible by the partnership into shares.
The Partnership used these funds for general working capital.

     From November 1998 through May 1999, Next Level Communications has provided
an additional $50.0 million of capital contribution in return for an increase in
its partnership interest from 89% to 90.4%. The Partnership used these funds for
general working capital.

     The sale of the above securities was deemed to be exempt from registration
under the Act in reliance upon Section 4(2) of the Act as transactions by an
issuer not involving any public offering. The recipients of securities in each
such transaction represented their intentions to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof and appropriate legends were affixed to the securities used
in such transactions. All recipients had adequate access, through their
relationships with the Registrant, to information about the Registrant.

(b) FINANCIAL STATEMENT SCHEDULES

     Schedules have been omitted because the information required to be set

ITEM 17. UNDERTAKINGS

     The Registrant hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation or the Bylaws of the Registrant, the Underwriting Agreement, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is
                                      II-3
<PAGE>   118

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 hereunder, 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 of 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.

     The Registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities
     Act, 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, 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.

corporation and a wholly owned subsidiary of General Instrument ("NLC CA"), Next
Level Communications L.P., a Delaware limited partnership (the "Partnership"),
and Next Level Communications, Inc., a Delaware corporation and a wholly owned
subsidiary of the Partnership ("NLC DE").

interest in the Partnership (the "GP Interest") and NLC CA holds a 90.424%
limited partnership interest in the Partnership (the "LP Interest").

            NLC DE was formed by the Partnership on August 24, 1999 for the
purpose of effecting the transactions contemplated hereby and an initial public
offering (the "Initial Public Offering") of the common stock of a successor

            NLC DE's authorized capital stock consists of 200 million shares of

Common Stock"), and 10 million shares of preferred stock, par value $.01 per
share, of which 100 shares of Common Stock are outstanding and held by the
Partnership. The terms of such classes of capital stock are set forth in the
certificate of incorporation of NLC DE attached hereto as Exhibit A.

            The boards of directors and the stockholders of NLC CA and NLC DE
and the partners of the Partnership have approved and adopted this Agreement in
accordance with the California General Corporation Law (the "CGCL"), the
Delaware General Corporation Law (the "DGCL"), and Delaware Revised Uniform

                      RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                         NEXT LEVEL COMMUNICATIONS, INC.

                        (Incorporated on August 24, 1999)


            FIRST: The name of the corporation is Next Level Communications,
Inc. (the "Corporation").

            SECOND: The address of the registered office of the Corporation in
the State of Delaware is 1209 Orange Street, in the City of Wilmington, County
of New Castle. The name of its registered agent at that address is The
Corporation Trust Company.

            THIRD: The purpose of the Corporation is to engage in any lawful act
or activity for which corporations may be organized under the Delaware General
Corporation Law as the same exists or may hereafter be amended (the "GCL").


            FOURTH: A. AUTHORIZATION. The total number of shares of stock that
the Corporation shall have authority to issue is 480,000,000 of which (i)
400,000,000 shares shall be shares of Common Stock, par value $.01 per share
(the "Common Stock"), (ii) 70,000,000 shares shall be shares of Class B
Non-Voting Common Stock, par value $.01 per share (the "Class B Common Stock"),
and (iii) 10,000,000 shares shall be shares of preferred stock, par value $.01
per share (the "Preferred Stock"). The number of authorized shares of any class
or classes of stock may be increased or decreased (but not below the number of
shares thereof then outstanding) by the affirmative vote of the holders of a
majority of the outstanding shares of Common Stock, without the separate vote of
any class or series of the Corporation's stock. Shares of Class B Common Stock
shall be issued only in connection with the Agreement and Plan of Merger dated
as of November 9, 1999 among General Instrument Corporation, Spencer Trask
Investors LLC, Next Level Communications, a California corporation, Next Level
Communications, L.P. and the Corporation.


            B. PREFERRED STOCK. The Board of Directors is expressly authorized
to provide for the issuance of all or any shares of the Preferred Stock in one
or more classes or series, and to fix for each such class or series the voting
powers (if any) and such distinctive designations, preferences and relative,
participating, optional or other special rights and such qualifications,
limitations or restrictions thereof, as shall be stated and expressed in the
resolution or resolutions adopted by the Board of Directors providing for the
issuance of such class or series and as may be permitted by the GCL, including,
without limitation, the authority to provide that any such class or series may
be (i) subject to redemption at such time or times and at such price or prices;
(ii) entitled to receive dividends (which may be cumulative or non-


<PAGE>   2
                                                                               2



cumulative) at such rates, on such conditions, and at such times, and payable in
preference to, or in such relation to, the dividends payable on any other class
or classes or any other series; (iii) entitled to such rights upon the
dissolution of, or upon any distribution of the assets of, the Corporation; or
(iv) convertible into, or exchangeable for, shares of any other class or classes
of stock, or of any other series of the same or any other class or classes of
stock, of the Corporation at such price or prices or at such rates of exchange
and with such adjustments; all as may be stated in such resolution or
resolutions.

            C. COMMON STOCK. The following is a statement of the relative
powers, preferences and participating, optional or other special rights, and the
qualifications, limitations and restrictions of the Common Stock and Class B
Common Stock of the Corporation:

            (1) Except as otherwise set forth below in paragraph (C)(2), the
relative powers, preferences and participating, optional or other special
rights, and the qualifications, limitations or restrictions of the Common Stock
and Class B Common Stock shall be identical in all respects.

            (2) At every meeting of the stockholders of the Corporation every
holder of Common Stock shall be entitled to one vote in person or by proxy for
each share of Common Stock standing in his or her name on the transfer books of
the Corporation in connection with the election of directors and all other
matters submitted to a vote of stockholders. Except as may be otherwise required
by law or by this Restated Certificate of Incorporation (the "Certificate of
Incorporation"), holders of Class B Common Stock shall not be entitled to vote.
No stockholder shall be entitled to exercise any right of cumulative voting.

            FIFTH: A. The business and affairs of the Corporation shall be
managed by or under the direction of a Board of Directors initially consisting
of five directors, the exact number of directors to be not less than three nor
more than twelve as determined from time to time exclusively by resolution
adopted by affirmative vote of a majority of the entire Board of Directors. The
directors shall be divided into three classes, designated Class I, Class II and
Class III. Each class shall consist, as nearly as may be possible, of one-third
of the total number of directors constituting the entire Board of Directors.
Class I directors shall be elected initially for a one-year term, Class II
directors initially for a two-year term and Class III directors initially for a
three-year term. At each succeeding annual meeting of stockholders beginning in
2000, successors to the class of directors whose term expires at that annual
meeting shall be elected for a three-year term. If the number of directors is
changed, any increase or decrease shall be apportioned among the classes so as
to maintain the number of directors in each class as nearly equal as possible,
and any additional director of any class elected to fill a vacancy resulting
from an increase in such class shall hold office for a term that shall coincide
with the remaining term of that class, but in no case will a decrease in the
number of directors shorten the term of any incumbent director. A director shall
hold office until the annual meeting


<PAGE>   3
                                                                               3



of the year in which his term expires and until his successor shall be elected
and shall qualify, subject, however, to prior death, resignation or removal from
office. Any vacancy on the Board of Directors may be filled by a majority of the
directors then in office, even if less than a quorum, or by a sole remaining
director or by stockholders if such vacancy was caused by the action of
stockholders (in which event such vacancy may not be filled by the directors or
a majority thereof). Any director elected to fill a vacancy not resulting from
an increase in the number of directors shall have the same remaining term as
that of his predecessor. Election of directors need not be by written ballot,
unless so provided in the By-laws of the Corporation.

            B. Any director or the entire Board of Directors may be removed,
with or without cause, by the affirmative vote of the holders of a majority of
the outstanding shares of Common Stock; provided, however, that after the
Trigger Date (as defined in paragraph (C) below), a director may not be removed
without cause.

            C. For purposes of this Certificate of Incorporation, "Trigger Date"
shall mean the first date on which General Instrument Corporation (General
Instrument Corporation, together with its successors, "General Instrument") and
its affiliates (as defined in Article SEVENTH) or the Majority Transferee (as
defined below) and its affiliates cease to beneficially own at least 49% of the
outstanding shares of Common Stock. Promptly upon becoming aware of the
occurrence of the Trigger Date, the Corporation shall promptly notify holders of
the Common Stock of such occurrence in any reasonably practicable manner.

            D. In the event that General Instrument transfers more than 50% of
the outstanding shares of Common Stock in a single transaction or group of
related transactions to one person (unaffiliated with General Instrument) or
group of affiliated persons (unaffiliated with General Instrument), such person
or group, together with their successors, shall be referred to herein as the
"Majority Transferee". For purposes of this paragraph D, each reference to a
"person" shall be deemed to include not only a natural person, but also a
corporation, partnership, joint venture, association, or legal entity of any
kind; each reference to a "natural person" (or to a "record holder" of shares,
if a natural person) shall be deemed to include in his or her representative
capacity a guardian, committee, executor, administrator or other legal
representative of such natural person or record holder.

            E. In addition to the powers and authority hereinbefore or by
statute expressly conferred upon them, the directors are hereby empowered to
exercise all such powers and do all such acts and things as may be exercised or
done by the Corporation, subject, nevertheless, to the provisions of the GCL,
this Certificate of Incorporation, and the By-laws of the Corporation; provided,
however, that no By-laws hereafter adopted shall invalidate any prior act of the
directors which would have been valid if such By-laws had not been adopted.

            F. Notwithstanding anything contained in this Certificate of
Incorporation to the contrary, after the Trigger Date, the affirmative vote of
the holders of at least 80% of the outstanding shares of Common Stock shall be
required to amend, repeal or adopt any provision inconsistent with this Article
FIFTH.

            SIXTH: A. In anticipation that General Instrument will remain a
substantial stockholder of the Corporation, and in anticipation that the
Corporation and General Instrument may engage in the same or similar activities
or lines of business and have an interest in the same areas of corporate
opportunities, and in recognition of the benefits to be derived by the
Corporation through its continued contractual, corporate and business relations
with General Instrument (including possible service of officers and directors of
General Instrument as officers and directors of the Corporation), the provisions
of this Article SIXTH are set forth to regulate and define the conduct of
certain affairs of the Corporation as they may involve General Instrument and
its officers and directors, and the powers, rights, duties and liabilities of
the Corporation and its officers, directors and stockholders in connection
therewith.

            B. General Instrument shall have no duty to refrain from engaging in
the same or similar activities or lines of business as the Corporation, and
neither General Instrument nor any officer or director thereof (except as
provided in paragraph (C) below) shall be liable to the Corporation or its
stockholders for breach of any fiduciary duty solely by reason of any such
activities of General Instrument. In the event that General Instrument acquires
knowledge of a potential transaction or matter which may be a corporate
opportunity for both General Instrument and the Corporation, General Instrument
shall have no duty to communicate or offer such corporate opportunity to the
Corporation and shall not be liable to the Corporation or its stockholders for
breach of any fiduciary duty as a stockholder of the Corporation solely by
reason of the fact that General Instrument pursues or acquires such corporate
opportunity for itself, directs such corporate opportunity to another person, or
does not communicate information regarding such corporate opportunity to the
Corporation.

            C. In the event that a director or officer of the Corporation who is
also a director or officer of General Instrument acquires knowledge of a
potential transaction or matter which may be a corporate opportunity for both
the Corporation and General Instrument, such director or officer of the
Corporation shall have fully satisfied and fulfilled the fiduciary duty of such
director or officer to the Corporation and its stockholders with respect to such
corporate opportunity, if such director or officer acts in a manner consistent
with the following policy:

            (i) A corporate opportunity offered to any person who is a director
      or officer of the Corporation, and who is also a director or officer of
      General Instrument, shall belong to the Corporation if such opportunity is
      expressly offered to such person in writing solely in his or her capacity
      as a director or officer of the Corporation.

                                                                               5



            (ii) Otherwise, such corporate opportunity shall belong to General
      Instrument.

            D. For purposes of this Article SIXTH only: (i) The term
"Corporation" shall mean the Corporation and all corporations, partnerships,
joint ventures, associations and other entities in which the Corporation
beneficially owns (directly or indirectly) 50% or more of the outstanding voting
stock, voting power, partnership interests or similar voting interests, and (b)
the term "General Instrument" shall mean General Instrument and all
corporations, partnerships, joint ventures, associations and other entities
which are affiliates (as defined in Article SEVENTH) of General Instrument
(other than the Corporation, defined in accordance with clause (i) of this
paragraph (D)).

            E. Any person or entity purchasing or otherwise acquiring any
interest in any shares of capital stock of the Corporation will be deemed to
have notice of and to have consented to the provisions of this Article SIXTH.

            F. Notwithstanding anything in this Certificate of Incorporation to
the contrary, (i) the foregoing provisions of this Article SIXTH shall expire on
the date that General Instrument ceases to own beneficially at least 20% of the
outstanding shares of Common Stock and no person who is a director or officer of
the Corporation is also a director or officer of General Instrument; and (ii) in
addition to any vote of the stockholders required by this Certificate of
Incorporation, until the time that General Instrument ceases to own beneficially
at least 20% of the outstanding shares of Common Stock, the affirmative vote of
the holders of more than 80% of the outstanding shares of Common Stock shall be
required to alter, amend or repeal, or adopt any provision inconsistent with,
any provision of this Article SIXTH. Neither the alteration, amendment or repeal
of this Article SIXTH nor the adoption of any provision of this Certificate of
Incorporation inconsistent with this Article SIXTH shall eliminate or reduce the
effect of this Article SIXTH in respect of any matter occurring, or any cause of
action, suit or claim that, but for this Article SIXTH, would accrue or arise,
prior to such alteration, amendment, repeal or adoption.

            SEVENTH: A. This Corporation shall not be governed by Section 203 of
the GCL. Notwithstanding any provision of the GCL, the Corporation shall not
engage in any business combination with any interested stockholder for a period
of three years following the time that such stockholder became an interested
stockholder, unless:

            (1) prior to such time the Board of Directors approved either the
business combination or the transaction which resulted in the stockholder
becoming an interested stockholder, or

            (2) upon consummation of the transaction which resulted in the
stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting


<PAGE>   6
                                                                               6



stock of the Corporation outstanding at the time the transaction commenced,
excluding for purposes of determining the number of shares outstanding those
shares owned (a) by persons who are directors and also officers and (b) employee
stock plans in which employee participants do not have the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer, or

            (3) at or subsequent to such time the business combination is
approved by the Board of Directors and authorized at an annual or special
meeting of stockholders, and not by written consent, by the affirmative vote of
at least 66-2/3% of the outstanding voting stock which is not owned by the
interested stockholder.

            B. The restrictions contained in this Article SEVENTH shall not
apply if:

            (1) the Corporation, by action of its stockholders, adopts an
amendment to the Certificate of Incorporation or the By-laws expressly electing
not to be governed by such restrictions, provided that, in addition to any other
vote required by law, such amendment to the Certificate of Incorporation or
By-laws must be approved by the affirmative vote of a majority of the shares
entitled to vote. An amendment adopted pursuant to this paragraph shall not be
effective until 12 months after the adoption of such amendment and shall not
apply to any business combination between the Corporation and any person who
became an interested stockholder of the Corporation on or prior to such
adoption. A By-law amendment adopted pursuant to this paragraph shall not be
further amended by the Board of Directors;

            (2) a stockholder becomes an interested stockholder inadvertently
and (a) as soon as practicable divests itself of ownership of sufficient shares
so that the stockholder ceases to be an interested stockholder and (b) would
not, at any time within the three year period immediately prior to a business
combination between the Corporation and such stockholder, have been an
interested stockholder but for the inadvertent acquisition of ownership; or

            (3) the business combination is proposed prior to consummation or
abandonment of and subsequent to the earlier of the public announcement or the
notice required under this Article SEVENTH of a proposed transaction which (a)
constitutes one of the transactions described in the second sentence of this
paragraph (B)(3); (b) is with or by a person who either was not an interested
stockholder during the previous three years or who became an interested
stockholder with the approval of the Board of Directors; and (c) is approved or
not opposed by a majority of the members of the Board of Directors then in
office (but not less than one) who were directors prior to any person becoming
an interested stockholder during the previous three years or were recommended
for election or elected to succeed such directors by a majority of such
directors. The proposed transactions referred to in the preceding sentence are
limited to (x) a merger or consolidation of the Corporation (except for a merger
in respect of which, pursuant to Section 251(f) of the GCL, no vote of the
stockholders of the Corporation is


<PAGE>   7
                                                                               7



required); (y) a sale, lease, exchange, mortgage, pledge, transfer or other
disposition (in one transaction or a series of transactions), whether as part of
a dissolution or otherwise, of assets of the Corporation or of any direct or
indirect majority-owned subsidiary of the Corporation (other than to any direct
or indirect wholly-owned subsidiary or to the Corporation) having an aggregate
market value equal to 50% or more of either the aggregate market value of all of
the assets of the Corporation determined on a consolidated basis or the
aggregate market value of all the outstanding stock of the Corporation; or (z) a
proposed tender or exchange offer for 50% or more of the outstanding voting
stock of the Corporation. The Corporation shall give not less than 20 days
notice to all interested stockholders prior to the consummation of any of the
transactions described in clauses (x) or (y) of the second sentence of this
paragraph (B)(3).

            C. As used herein, the term:

            (1) "affiliate" means a person that directly, or indirectly through
one or more intermediaries, controls, or is controlled by, or is under common
control with, another person.

            (2) "associate," when used to indicate a relationship with any
person, means (i) any corporation, partnership, unincorporated association or
other entity of which such person is a director, officer or partner or is,
directly or indirectly, the owner of 20% or more of any class of voting stock,
(ii) any trust or other estate in which such person has at least a 20%
beneficial interest or as to which such person serves as trustee or in a similar
fiduciary capacity, and (iii) any relative or spouse of such person, or any
relative of such spouse, who has the same residence as such person.

            (3) "business combination," when used in reference to any
corporation and any interested stockholder of such corporation, means:

            (a) any merger or consolidation of the corporation or any direct or
      indirect majority-owned subsidiary of the corporation with (A) the
      interested stockholder, or (B) with any other corporation, partnership,
      unincorporated association or other entity if the merger or consolidation
      is caused by the interested stockholder and as a result of such merger or
      consolidation paragraph A of this Article SEVENTH is not applicable to the
      surviving entity;

            (b) any sale, lease, exchange, mortgage, pledge, transfer or other
      disposition (in one transaction or a series of transactions), except
      proportionately as a stockholder of such corporation, to or with the
      interested stockholder, whether as part of a dissolution or otherwise, of
      assets of the corporation or of any direct or indirect majority-owned
      subsidiary of the corporation which assets have an aggregate market value
      equal to 10% or more of either the aggregate market value of all the
      assets of the corporation


<PAGE>   8
                                                                               8



      determined on a consolidated basis or the aggregate market value of all
      the outstanding stock of the corporation;

            (c) any transaction which results in the issuance or transfer by the
      corporation or by any direct or indirect majority-owned subsidiary of the
      corporation of any stock of the corporation or of such subsidiary to the
      interested stockholder, except (A) pursuant to the exercise, exchange or
      conversion of securities exercisable for, exchangeable for or convertible
      into stock of such corporation or any such subsidiary which securities
      were outstanding prior to the time that the interested stockholder became
      such, (B) pursuant to a merger under Section 251(g) of the GCL; (C)
      pursuant to a dividend or distribution paid or made, or the exercise,
      exchange or conversion of securities exercisable for, exchangeable for or
      convertible into stock of the corporation or any such subsidiary which
      security is distributed, pro rata to all holders of a class or series of
      stock of the corporation subsequent to the time the interested stockholder
      became such, (D) pursuant to an exchange offer by the corporation to
      purchase stock made on the same terms to all holders of said stock, or (E)
      any issuance or transfer of stock by the corporation, provided, however,
      that in no case under (C) -- (E) above shall there be an increase in the
      interested stockholder's proportionate share of the stock of any class or
      series of the corporation or of the voting stock of the corporation;

            (d) any transaction involving the corporation or any direct or
      indirect majority-owned subsidiary of the corporation which has the
      effect, directly or indirectly, of increasing the proportionate share of
      the stock of any class or series, or securities convertible into the stock
      of any class or series, of the corporation or of any such subsidiary which
      is owned by the interested stockholder, except as a result of immaterial
      changes due to fractional share adjustments or as a result of any purchase
      or redemption of any shares of stock not caused, directly or indirectly,
      by the interested stockholder; or

            (e) any receipt by the interested stockholder of the benefit,
      directly or indirectly (except proportionately as a stockholder of such
      corporation) of any loans, advances, guarantees, pledges, or other
      financial benefits (other than those expressly permitted in subparagraphs
      (a) -- (d) above) provided by or through the corporation or any direct or
      indirect majority-owned subsidiary.

            (4) "control," including the term "controlling," "controlled by" and
"under common control with," means the possession, directly or indirectly, of
the power to direct or cause the direction of the management and policies of a
person, whether through the ownership of voting stock, by contract, or
otherwise. A person who is the owner of 20% or more of the outstanding voting
stock of any corporation, partnership, unincorporated association or other
entity shall be presumed to have control of such entity, in the absence of proof
by a preponderance of the evidence to the contrary. Notwithstanding the
foregoing, a presumption of


<PAGE>   9
                                                                               9



control shall not apply where such person holds voting stock, in good faith and
not for the purpose of circumventing this section, as an agent, bank, broker,
nominee, custodian or trustee for one or more owners who do not individually or
as a group have control of such entity.

            (5) "interested stockholder" means any person (other than the
Corporation and any direct or indirect majority-owned subsidiary of the
Corporation and other than General Instrument and its affiliates and the
Majority Transferee and its affiliates) that (i) is the owner of 15% or more of
the outstanding voting stock of the Corporation or (ii) is an affiliate or
associate of the Corporation and was the owner of 15% or more of the outstanding
voting stock of the Corporation at any time within the three year period
immediately prior to the date on which it is sought to be determined whether
such person is an interested stockholder, and the affiliates and associates of
such person; provided, however, that the term "interested stockholder" shall not
include any person whose ownership of shares in excess of the 15% limitation set
forth herein in the result of action taken solely by the Corporation provided
that such person shall be an interested stockholder if thereafter such person
acquires additional shares of voting stock of the Corporation, except as a
result of further corporate action not caused, directly or indirectly, by such
person. For the purpose of determining whether a person is an interested
stockholder, the voting stock of the Corporation deemed to be outstanding shall
include stock deemed to be owned by the person through application of paragraph
(C)(8) but shall not include any other unissued stock of the Corporation which
may be issuable pursuant to any agreement, arrangement or understanding, or upon
exercise of conversion rights, warrants or options, or otherwise.

            (6) "person" means any individual, corporation, partnership,
unincorporated association or other entity.

            (7) "stock" means, with respect to any corporation, capital stock
and, with respect to any other entity, any equity interest.

            (8) "voting stock" means, with respect to any corporation, stock of
any class or series entitled to vote generally in the election of directors and,
with respect to any entity that is not a corporation, any equity interest
entitled to vote generally in the election of the governing body of such entity.

            (9) "owner" including the terms "own" and "owned" when used with
respect to any stock means a person that individually or with or through any of
its affiliates or associates:

            (a) beneficially owns such stock, directly or indirectly; or


<PAGE>   10
                                                                              10



            (b) has (i) the right to acquire such stock (whether such right is
      exercisable immediately or only after the passage of time) pursuant to any
      agreement, arrangement or understanding, or upon the exercise of
      conversion rights, exchange rights, warrants or options, or otherwise;
      provided, however, that a person shall not be deemed the owner of stock
      tendered pursuant to a tender or exchange offer made by such person or any
      of such person's affiliates or associates until such tendered stock is
      accepted for purchase or exchange; or (ii) the right to vote such stock
      pursuant to any agreement, arrangement or understanding; provided,
      however, that a person shall not be deemed the owner of any stock because
      of such person's right to vote such stock if the agreement, arrangement or
      understanding to vote such stock arises solely from a revocable proxy or
      consent given in response to a proxy or consent solicitation made to ten
      or more persons; or

            (c) has any agreement, arrangement or understanding for the purpose
      of acquiring, holding, voting (except voting pursuant to a revocable proxy
      or consent as described in item (ii) of clause (b) of this paragraph
      (C)(9)), or disposing of such stock with any other person that
      beneficially owns, or whose affiliates or associates beneficially own,
      directly or indirectly, such stock.

            D. Notwithstanding anything contained in this Certificate of
Incorporation to the contrary, after the Trigger Date, the affirmative vote of
the holders of at least 80% of the outstanding shares of Common Stock shall be
required to amend, repeal or adopt any provision inconsistent with this Article
SEVENTH.

            EIGHTH: A. Meetings of stockholders may be held within or without
the State of Delaware, as the By-laws may provide. The books of the Corporation
may be kept (subject to any provision contained in the GCL) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the By-laws of the Corporation.

            B. Any action required or permitted to be taken by the stockholders
of the Corporation may be effected by a consent in writing by such holders in
accordance with Section 228 of the GCL; provided, however, that, on and after
the Trigger Date, any action required or permitted to be taken by the
stockholders of the Corporation may be effected only at a duly called annual or
special meeting of such holders and may not be effected by a consent in writing
by such holders in lieu of such a meeting.

            C. Except as otherwise required by law, special meetings of
stockholders of the Corporation for any purpose or purposes may be called only
by the Chairman of the Board of Directors or the Chief Executive Officer or by
any officer at the request in writing of a majority of the Board of Directors
or, prior to the Trigger Date, by the holders of a majority of the



<PAGE>   11
                                                                              11



outstanding shares of Common Stock. No business other than that stated in the
notice of such meeting shall be transacted at any special meeting.

            D. Notwithstanding anything contained in this Certificate of
Incorporation to the contrary, after the Trigger Date, the affirmative vote of
the holders of at least 80% of the outstanding shares of Common Stock shall be
required to amend, repeal or adopt any provision inconsistent with this Article
EIGHTH.
            NINTH: 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 any breach of the
director's duty of loyalty to the Corporation or its stockholders, for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, under Section 174 of the GCL or for any transaction from which
the director derived an improper personal benefit. If the GCL is amended after
approval by the stockholders of this Article NINTH to authorize corporate action
further eliminating or limiting the personal liability of directors, then the
liability of a director of the Corporation shall be eliminated or limited to the
fullest extent permitted by the GCL, as so amended. Any repeal or modification
of this Article NINTH by the stockholders of the Corporation shall not adversely
affect any right or protection of a director of the Corporation existing at the
time of such repeal or modification.

            TENTH: A. Each person who was or is made a party to or is threatened
to be made a party to or is involved in any action, suit or proceeding, whether
civil, criminal, administrative, investigative or otherwise (hereinafter a
"proceeding"), by reason of the fact that he or she, or a person of whom he or
she is the legal representative, is or was a director or officer of the
Corporation or is or was serving at the request of the Corporation as a director
or officer of another corporation or of a partnership, joint venture, trust or
other enterprise, including service with respect to employee benefit plans,
whether the basis of such proceeding is alleged action in an official capacity
as a director or officer or in any other capacity while serving as a director or
officer, shall be indemnified and held harmless by the Corporation to the
fullest extent authorized by the GCL, as the same exists or may hereafter be
amended (but, in the case of any such amendment, only to the extent that such
amendment permits the Corporation to provide broader indemnification rights than
said law permitted the Corporation to provide prior to such amendment), against
all expense, liability and loss reasonably incurred or suffered by such person
in connection therewith and such indemnification shall continue as to a person
who has ceased to be a director or officer and shall inure to the benefit of his
or her heirs, executors and administrators; provided, however, that the
Corporation shall indemnify any such person seeking indemnification in
connection with a proceeding (or part thereof) initiated by such person (other
than pursuant to paragraph (B) of this Article TENTH) only if such proceeding
(or part thereof) was authorized by the Board of Directors of the Corporation.
The right to indemnification conferred in this paragraph (A) of Article TENTH
shall be a contract right and


<PAGE>   12
                                                                              12



shall include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
however, that if the GCL requires, the payment of such expenses incurred by a
director or officer in his or her capacity as a director or officer (and not in
any other capacity in which service was or is rendered by such person while a
director or officer) in advance of the final disposition of a proceeding shall
be made only upon delivery to the Corporation of an undertaking, by or on behalf
of such director or officer, to repay all amounts so advanced if it shall
ultimately be determined that such director or officer is not entitled to be
indemnified under this paragraph (A) of Article TENTH or otherwise.

            B. If a claim which the Corporation is obligated to pay under
paragraph (A) of this Article TENTH is not paid in full by the Corporation
within 60 days after a written claim has been received by the Corporation, the
claimant may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim and, if successful in whole or in part,
the claimant shall be entitled to be paid also the expense of prosecuting such
claim. It shall be a defense to any such action (other than an action brought to
enforce a claim for expenses incurred in defending any proceeding in advance of
its final disposition where the required undertaking, if any is required, has
been tendered to the Corporation) that the claimant has not met the standards of
conduct which make it permissible under the GCL for the Corporation to indemnify
the claimant for the amount claimed, but the burden of proving such defense
shall be on the Corporation. Neither the failure of the Corporation (including
its Board of Directors, independent legal counsel or its stockholders) to have
made a determination prior to the commencement of such action that
indemnification of the claimant is proper in the circumstances because he or she
has met the applicable standard of conduct set forth in the GCL, nor an actual
determination by the Corporation (including its Board of Directors, independent
legal counsel or its stockholders) that the claimant has not met such applicable
standard of conduct, shall be a defense to the action or create a presumption
that the claimant has not met the applicable standard of conduct.

            C. The provisions of this Article TENTH shall cover claims, actions,
suits and proceedings, civil or criminal, whether now pending or hereafter
commenced and shall be retroactive to cover acts or omissions or alleged acts or
omissions which heretofore have taken place. If any part of this Article TENTH
should be found to be invalid or ineffective in any proceeding, the validity and
effect of the remaining provisions shall not be affected.

            D. The right to indemnification and the payment of expenses incurred
in defending a proceeding in advance of its final disposition conferred in this
Article TENTH shall not be exclusive of any other right which any person may
have or hereafter acquire under any statute, provision of this Certificate of
Incorporation, By-law, agreement, vote of stockholders or disinterested
directors or otherwise.

                                                                              13



            E. The Corporation may maintain insurance, at its expense, to
protect itself and any director, officer, employee or agent of the Corporation
or another corporation, partnership, joint venture, trust or other enterprise
against any such expense, liability or loss, whether or not the Corporation
would have the power to indemnify such person against such expense, liability or
loss under the GCL.

            F. The Corporation may, to the extent authorized from time to time
by the Board of Directors, grant rights to indemnification, and rights to be
paid by the Corporation the expenses incurred in defending any proceeding in
advance of its final disposition, to any employee or agent of the Corporation to
the fullest extent of the provisions of this Article TENTH with respect to the
indemnification and advancement of expenses of directors or officers of the
Corporation.

            ELEVENTH: The By-laws of the Corporation may be altered, amended or
repealed at any meeting of the Board of Directors or of the stockholders,
provided that notice of such alteration, amendment or repeal be contained in the
notice of such meeting of the Board of Directors or stockholders, as the case
may be. All such amendments must be approved by the affirmative vote of the
holders of a majority of the outstanding shares of Common Stock (if effected by
action of the stockholders prior to the Trigger Date), by the affirmative vote
of the holders of at least 80% of the outstanding shares of Common Stock (if
effected by action of the stockholders on or after the Trigger Date), or by the
affirmative vote of directors constituting not less than a majority of the
entire Board of Directors (if effected by action of the Board of Directors).

            TWELFTH: The Corporation reserves the right to amend, alter, change
or repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by the law of the State of Delaware, and all
rights of the stockholders herein are granted subject to this reservation.

                               REGISTRATION RIGHTS

            2.1 Demand Registration - Registrable Securities.

(a) Upon written notice provided (i) at any time from General Instrument
requesting that Next Level effect the registration under the Securities Act of
any or all of the Registrable Securities held by the GI Holders or (ii) at any
time from Spencer Trask requesting that Next Level effect the registration under
the Securities Act of any or all of the Registrable Securities held by the ST
Holders, each of which notices shall specify the intended method or methods of
disposition of such Registrable Securities, Next Level shall use its best
efforts to effect the registration under the Securities Act and applicable state
securities laws of such Registrable Securities for disposition in accordance
with the intended method or methods of disposition stated in such request
(including in a Rule 415 Offering, if Next Level is then eligible to register
such Registrable Securities on Form S-3 (or a successor form) for such
offering); provided that,

            (i) with respect to any registration statement filed, or to be
      filed, pursuant to this Section 2.1, if Next Level shall furnish to the
      Holders that have made such request a certified resolution of the Board of
      Directors of Next Level stating that in the Board of Directors' good faith
      judgment it would (because of the existence of, or in anticipation of, any
      acquisition or financing activity, or the unavailability for reasons
      beyond Next Level's reasonable control of any required financial
      statements, or any other event or condition of similar significance to
      Next Level) be significantly disadvantageous (a "Disadvantageous
      Condition") to Next Level for such a registration statement


<PAGE>   5
                                                                               5



      to be maintained effective, or to be filed and become effective, and
      setting forth the general reasons for such judgment, Next Level shall be
      entitled to cause such registration statement to be withdrawn and the
      effectiveness of such registration statement terminated, or, in the event
      no registration statement has yet been filed, shall be entitled not to
      file any such registration statement, until such Disadvantageous Condition
      no longer exists (notice of which Next Level shall promptly deliver to
      such Holders). Upon receipt of any such notice of a Disadvantageous
      Condition, such Holders shall forthwith discontinue use of the prospectus
      contained in such registration statement and, if so directed by Next
      Level, each such Holder will deliver to Next Level all copies, other than
      permanent file copies then in such Holder's possession, of the prospectus
      then covering such Registrable Securities current at the time of receipt
      of such notice; provided, that the filing of any such registration
      statement may not be delayed for a period in excess of 60 days in any
      calendar year due to the occurrence of one or more Disadvantageous
      Conditions;

            (ii) after the General Instrument Ownership Reduction, the GI
      Holders may collectively exercise their rights under this Section 2.1
      (through notice delivered by the GI Holders owning in the aggregate a
      majority in economic interest of the Registrable Securities then held by
      the GI Holders) on not more than four occasions (it being acknowledged
      that prior to the General Instrument Ownership Reduction, there shall be
      no limit to the number of occasions on which the GI Holders may exercise
      such rights);

            (iii) the ST Holders may collectively exercise their rights under
      this Section 2.1 (through notice delivered by Spencer Trask) on not more
      than three occasions;

            (iv) except as otherwise provided in Section 2.2 or elsewhere in
      this Agreement, the Holders shall not have the right to exercise
      registration rights pursuant to this Section 2.1 within the 180-day period
      following the date hereof or following the registration and sale of
      Registrable Securities effected pursuant to a prior exercise of the
      registration rights provided in this Section 2.1.

            (b) Notwithstanding any other provision of this Agreement to the
contrary, a registration requested by a Holder pursuant to this Section 2.1
shall not be deemed to have been effected (and, therefore, not requested for
purposes of paragraph (a) above), (i) if it shall not have become effective,
(ii) if after it has become effective such registration is interfered with by
any stop order, injunction or other order or requirement


<PAGE>   6
                                                                               6



of the SEC or other governmental agency or court for any reason other than a
misrepresentation or an omission by a Holder or cease to be maintained effective
due to a Disadvantageous Condition and, as a result thereof, the Registrable
Securities requested to be registered cannot be completely distributed in
accordance with the plan of distribution set forth in the related registration
statement or (iii) if the conditions to closing specified in the purchase
agreement or underwriting agreement entered into in connection with such
registration are not satisfied or waived other than by reason of some act or
omission by a Holder within its control.

            (c) In the event that any registration pursuant to this Section 2.1
shall involve, in whole or in part, an underwritten offering, the Holders of a
majority of the Registrable Securities to be registered pursuant to this Section
2.1 shall have the right to designate an underwriter or underwriters reasonably
acceptable to Next Level as the lead or managing underwriters of such
underwritten offering and, in connection with each registration pursuant to this
Section 2.1, such Holders may select one counsel reasonably acceptable to Next
Level to represent all such Holders.

            (d) Next Level shall have the right to cause the registration of
additional equity securities for sale for its account or any existing or former
directors, officers or employees of the Next Level Entities in any registration
of Registrable Securities requested for the benefit of the GI Holders or the ST
Holders, as the case may be, pursuant to paragraph (a) above; provided, however,
that, if such Holders are advised in writing (with a copy to Next Level) by a
nationally recognized investment banking firm selected by such Holders
reasonably acceptable to Next Level (which shall be the lead underwriter or a
managing underwriter in the case of an underwritten offering) that, in such
firm's good faith view, the inclusion of such additional equity securities in
such registration would be likely to have an adverse effect on the price, timing
or distribution of the offering and sale of the Registrable Securities then
contemplated by such Holders, the registration of such additional equity
securities or part thereof shall not be permitted. The Holders of the
Registrable Securities to be registered pursuant to this Section 2.1 may require
that any such additional equity securities be included in the offering proposed
by such Holders on the same conditions as the Registrable Securities that are
included therein. In the event that the number of Registrable Securities
requested to be included in such registration by such Holders exceeds the number
which, in the good faith view (delivered in writing) of such investment banking
firm, can be sold without adversely affecting the price, timing, distribution or
sale of securities in the

<PAGE>   7
                                                                               7



offering, the number shall be allocated pro rata among the requesting Holders on
the basis of the relative number of Registrable Securities then held by each
such Holder (provided that any number in excess of a Holder's request may be
reallocated among the remaining requesting Holders in a like manner).

            2.2 Piggyback Registration. In the event that Next Level at any time
after the date hereof proposes to register any Common Stock or any securities
convertible into or exchangeable for Common Stock under the Securities Act,
whether or not for sale for its own account and including pursuant to Section
2.1 (such stock or securities, "Other Securities"), in a manner that would
permit registration of Registrable Securities for sale for cash to the public
under the Securities Act, it shall at each such time give prompt written notice
to each of the Holders of its intention to do so and of the rights of such
Holders under this Section 2.2. Subject to the terms and conditions hereof, such
notice shall offer each such Holder the opportunity to include in such
registration statement such number of Registrable Securities as such Holder may
request. Upon the written request of any such Holder made within 15 days after
the receipt of Next Level's notice (which request shall specify the number of
Registrable Securities intended to be disposed of and the intended method of
disposition thereof), Next Level shall use its best efforts to effect, in
connection with the registration of the Other Securities, the registration under
the Securities Act of all Registrable Securities which Next Level has been so
requested to register, to the extent required to permit the disposition (in
accordance with such intended method of disposition thereof) of the Registrable
Securities so requested to be registered; provided, that:

            (a) if, at any time after giving such written notice of its
intention to register any Other Securities and prior to the effective date of
the registration statement filed in connection with such registration, Next
Level shall determine for any reason not to register the Other Securities, Next
Level may, at its election, give written notice of such determination to such
Holders and thereupon Next Level shall be relieved of its obligation to register
such Registrable Securities in connection with the registration of such Other
Securities, without prejudice, however, to the rights of the Holders immediately
to request that such registration be effected as a registration under Section
2.1 to the extent permitted thereunder;

            (b) if a nationally recognized investment banking firm selected by
Next Level advises Next Level in writing that, in such firm's good faith view,
all or a part of such Registrable Securities cannot be sold and the inclusion of
all or a part of

                                                                               8



such Registrable Securities in such registration would be likely to have an
adverse effect upon the price, timing or distribution of the offering and sale
of the Other Securities then contemplated, Next Level shall include in such
registration: (i) first, the Other Securities being sold for its own account or
the Other Securities which are Registrable Securities included pursuant to
Section 2.1 and/or, if such registration is being effected after the General
Instrument Ownership Reduction, any Other Securities being registered pursuant
to any demand registration rights held by Persons other than Next Level and the
Holders and (ii) second, up to the full number of Registrable Securities
requested to be included pursuant to this Section 2.2 and the remaining Other
Securities that are requested to be included in such registration in excess of
the number of securities referred to in clause (i) which, in the good faith view
of such investment banking firm, can be sold without adversely affecting such
offering, such full number to be allocated pro rata among the holders of the
securities referred to in this clause (ii) based on the relative number of
securities requested to be included by each such holder(provided further that,
in the event that such investment banking firm advises in writing that less than
all of such Registrable Securities may be included in such offering, one or more
of such Holders may withdraw their request for registration of their Registrable
Securities under this Section 2.2 and 90 days subsequent to the effective date
of the registration statement for the registration of such Other Securities
request that such registration be effected as a registration under Section 2.1
to the extent permitted thereunder);

            (c) Next Level shall not be required to effect any registration of
Registrable Securities under this Section 2.2 incidental to the registration of
any of its securities in connection with mergers, acquisitions, exchange offers,
subscription offers, dividend reinvestment plans or stock option or other
executive or employee benefit or compensation plans; and

            (d) no registration of Registrable Securities effected under this
Section 2.2 shall relieve Next Level of its obligation to effect a registration
of Registrable Securities pursuant to Section 2.1.

            2.3 Expenses. Next Level shall pay all Registration Expenses with
respect to a particular offering (or proposed offering). Notwithstanding the
foregoing, each of the Holders and Next Level shall be responsible for its own
internal administrative and similar costs, which shall not constitute
Registration Expenses.

            2.4 Registration and Qualification. If and whenever Next Level is
required to effect the registration of any Registrable Securities under the
Securities Act as provided in Sections 2.1 or 2.2, Next Level shall as promptly
as practicable:

            (a) prepare, file and use its best efforts to cause to become
effective a registration statement under the Securities Act relating to the
Registrable Securities to be offered;

            (b) prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection therewith as
may be necessary to keep such registration statement effective and to comply
with the provisions of the Securities Act with respect to the disposition of all
Registrable Securities until the earlier of (A) such time as all of such
Registrable Securities have been disposed of in accordance with the intended
methods of disposition set forth in such registration statement and (B) the
expiration of three months after such registration statement becomes effective;
provided, that such three-month period shall be extended for such number of days
that equals the number of days elapsing from (x) the date the written notice
contemplated by paragraph (f) below is given by Next Level to (y) the date on
which Next Level delivers to the Holders of Registrable Securities the
supplement or amendment contemplated by paragraph (f) below;

            (c) furnish to the Holders of Registrable Securities and to any
underwriter of such Registrable Securities such number of conformed copies of
such registration statement and of each such amendment and supplement thereto
(in each case including all exhibits), such number of copies of the prospectus
included in such registration statement (including each preliminary prospectus
and any summary prospectus), in conformity with the requirements of the
Securities Act, such documents incorporated by reference in such registration
statement or prospectus, and such other documents, as the Holders of Registrable
Securities or such underwriter may reasonably request, and upon request a copy
of any and all transmittal letters or other correspondence to or received from,
the SEC or any other governmental agency or self-regulatory body or other body
having jurisdiction (including any domestic or foreign securities exchange)
relating to such offering;

            (d) use its best efforts to register or qualify all Registrable
Securities covered by such registration statement under the securities or blue
sky laws of such U.S. jurisdictions as the Holders of such Registrable
Securities or any underwriter to such Registrable Securities shall reasonably
request, and use its reasonable best efforts to obtain all appropriate
registrations, permits and consents in connection therewith, and


<PAGE>   10
                                                                              10



do any and all other acts and things which may be necessary or advisable to
enable the Holders of Registrable Securities or any such underwriter to
consummate the disposition in such jurisdictions of its Registrable Securities
covered by such registration statement; provided, that Next Level shall not for
any such purpose be required to qualify generally to do business as a foreign
corporation in any such jurisdiction wherein it is not so qualified or to
consent to general service of process in any such jurisdiction;

            (e) (i) use its best efforts to furnish to each of the Holders of
Registrable Securities included in such registration (each, a "Selling Holder")
and to any underwriter of such Registrable Securities an opinion of counsel for
Next Level addressed to each Selling Holder and dated the date of the closing
under the underwriting agreement (if any) (or if such offering is not
underwritten, dated the effective date of the registration statement) and (ii)
use its best efforts to furnish to each Selling Holder a "cold comfort" letter
addressed to each Selling Holder and signed by the independent public
accountants who have audited the financial statements of Next Level included in
such registration statement, in each such case covering substantially the same
matters with respect to such registration statement (and the prospectus included
therein) as are customarily covered in opinions of issuer's counsel and in
accountants' letters delivered to underwriters in underwritten public offerings
of securities and such other matters as the Selling Holders may reasonably
request and, in the case of such accountants' letter, with respect to events
subsequent to the date of such financial statements;

            (f) as promptly as practicable, notify the Selling Holders in
writing (i) at any time when a prospectus relating to a registration pursuant to
Sections 2.1 or 2.2 is required to be delivered under the Securities Act of the
happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading and (ii) of any request by the SEC or any
other regulatory body or other body having jurisdiction for any amendment of or
supplement to any registration statement or other document relating to such
offering, and in either such case, at the request of the Selling Holders prepare
and furnish to the Selling Holders a reasonable number of copies of a supplement
to or an amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus
shall not include an untrue statement of a material fact or omit to state a
material fact required to


<PAGE>   11
                                                                              11



be stated therein or necessary to make the statements therein, in light of the
circumstances under which they are made, not misleading;

            (g) if requested by the lead or managing underwriters, use its best
efforts to list all such Registrable Securities covered by such registration on
each securities exchange and automated inter-dealer quotation system on which
common equity securities of Next Level are then listed;

            (h) to the extent reasonably requested by the lead or managing
underwriters, send appropriate officers of Next Level to attend and participate
in any "road shows" scheduled in connection with any such registration, with all
out-of-pocket costs and expense incurred by Next Level or such officers in
connection with such attendance to be paid by Next Level; and

            (i) furnish for delivery in connection with the closing of any
offering of Registrable Securities pursuant to a registration effected pursuant
to Sections 2.1 or 2.2 unlegended certificates representing ownership of the
Registrable Securities being sold in such denominations as shall be requested by
the Selling Holders or the underwriters.

            2.5 Conversion of other Securities, Etc. In the event that any
Holder offers any options, rights, warrants or other securities issued by it or
any other Person that are offered with, convertible into or exercisable or
exchangeable for any Registrable Securities, the Registrable Securities
underlying such options, rights, warrants or other securities shall continue to
be eligible for registration pursuant to Sections 2.1 and 2.2.

            2.6 Underwriting; Due Diligence. (a) If requested by the
underwriters for any underwritten offering of Registrable Securities pursuant to
a registration requested under this Agreement, Next Level shall enter into an
underwriting agreement with such underwriters for such offering, which agreement
will contain such representations and warranties by Next Level and such other
terms and provisions as are customarily contained in underwriting agreements of
Next Level to the extent relevant and as are customarily contained in
underwriting agreements generally with respect to secondary distributions to the
extent relevant, including, without limitation, indemnification and contribution
provisions substantially to the effect and to the extent provided in Section
2.7, and agreements as to the provision of opinions of counsel and accountants'
letters to the effect and to the extent provided in Section 2.4(e). The Selling
Holders on whose behalf the Registrable Securities are to be distributed by such
underwriters shall be parties to any such underwriting agreement and the
representations and warranties by, and the other


<PAGE>   12
                                                                              12



agreements on the part of, Next Level to and for the benefit of such
underwriters, shall also be made to and for the benefit of such Selling Holders.
Such underwriting agreement shall also contain such representations and
warranties by such Selling Holders and such other terms and provisions as are
customarily contained in underwriting agreements with respect to secondary
distributions, when relevant, including, without limitation, indemnification and
contribution provisions substantially to the effect and to the extent provided
in Section 2.7.

            (b) In connection with the preparation and filing of each
registration statement registering Registrable Securities under the Securities
Act pursuant to this Agreement, Next Level shall give the Holders of such
Registrable Securities and the underwriters, if any, and their respective
counsel and accountants, such reasonable and customary access to its books and
records and such opportunities to discuss the business of Next Level with its
officers and the independent public accountants who have certified the financial
statements of Next Level as shall be necessary, in the opinion of such Holders
and such underwriters or their respective counsel, to conduct a reasonable
investigation within the meaning of the Securities Act.

            2.7 Indemnification and Contribution. (a) In the case of each
offering of Registrable Securities made pursuant to this Agreement, Next Level
agrees to indemnify and hold harmless, to the extent permitted by law, each of
the Selling Holders, each underwriter of Registrable Securities so offered and
each Person, if any, who controls any of the foregoing Persons within the
meaning of the Securities Act and the officers, directors, affiliates, employees
and agents of each of the foregoing, against any and all losses, liabilities,
costs (including reasonable attorney's fees and disbursements and reasonable
costs of investigation and preparation), claims and damages, joint or several,
to which they or any of them may become subject, under the Securities Act or
otherwise, including any amount paid in settlement of any litigation commenced
or threatened, insofar as such losses, liabilities, costs, claims and damages
(or actions or proceedings in respect thereof, whether or not such indemnified
Person is a party thereto) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the registration
statement (or in any preliminary or final prospectus included therein) or in any
offering memorandum or other offering document relating to the offering and sale
of such Registrable Securities, or any amendment thereof or supplement thereto,
or in any document incorporated by reference therein, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not


<PAGE>   13
                                                                              13



misleading; provided, however that Next Level shall not be liable to any Person
in any such case to the extent that any such loss, liability, cost, claim or
damage arises out of or relates to any untrue statement or alleged untrue
statement, or any omission, if such statement or omission shall have been made
in reliance upon and in conformity with information relating to a Selling
Holder, another holder of securities included in such registration statement or
underwriter furnished in writing to Next Level by or on behalf of such Selling
Holder, other holder or underwriter specifically for use in the registration
statement (or in any preliminary or final prospectus included therein), offering
memorandum or other offering document, or any amendment thereof or supplement
thereto. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of any Selling Holder, any other holder or
any underwriter and shall survive the transfer of such securities. The foregoing
indemnity agreement is in addition to any liability that Next Level may
otherwise have to each Selling Holder, other holder or underwriter of the
Registrable Securities or any controlling person of the foregoing and the
officers, directors, affiliates, employees and agents of each of the foregoing;
provided, further, that, in the case of an offering with respect to which a
Selling Holder has designated the lead or managing underwriters (or a Selling
Holder is offering Registrable Securities directly, without an underwriter),
this indemnity does not apply to any loss, liability, cost, claim or damage
arising out of or relating to any untrue statement or alleged untrue statement
or omission or alleged omission in any preliminary prospectus or offering
memorandum if a copy of a final prospectus or offering memorandum was available
on a timely basis and not sent or given by or on behalf of any underwriter (or
such Selling Holder or other holder, as the case may be) to such Person
asserting such loss, liability, cost, claim or damage at or prior to the written
confirmation of the sale of the Registrable Securities as required by the
Securities Act and such untrue statement or omission had been corrected in such
final prospectus or offering memorandum.

            (b) In the case of each offering made pursuant to this Agreement,
each Selling Holder, by exercising its registration rights hereunder, agrees to
indemnify and hold harmless, and to use reasonable best efforts to cause each
underwriter of Registrable Securities included in such offering (in the same
manner and to the same extent as set forth in Section 2.7(a)) to agree to
indemnify and hold harmless, Next Level, each other underwriter who participates
in such offering, each other Selling Holder or other holder with securities
included in such offering and in the case of an underwriter, such Selling Holder
or other holder, and each Person, if any, who controls any of the foregoing
within the meaning of the Securities Act and the


<PAGE>   14
                                                                              14



officers, directors, affiliates, employees and agents of each of the foregoing,
against any and all losses, liabilities, costs (including reasonable attorney's
fees and disbursements and reasonable costs of investigation and preparation),
claims and damages to which they or any of them may become subject, under the
Securities Act or otherwise, including any amount paid in settlement of any
litigation commenced or threatened, insofar as such losses, liabilities, costs,
claims and damages (or actions or proceedings in respect thereof, whether or not
such indemnified Person is a party thereto) arise out of or are based upon any
untrue statement or alleged untrue statement by such Selling Holder or
underwriter, as the case may be, of a material fact contained in the
registration statement (or in any preliminary or final prospectus included
therein) or in any offering memorandum or other offering document relating to
the offering and sale of such Registrable Securities prepared by Next Level or
at its direction, or any amendment thereof or supplement thereto, or any
omission by such Selling Holder or underwriter, as the case may be, or alleged
omission by such Selling Holder or underwriter, as the case may be, of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, but in each case only to the extent that such untrue
statement of a material fact is contained in, or such material fact is omitted
from information relating to such Selling Holder or underwriter, as the case may
be, furnished in writing to Next Level by or on behalf of such Selling Holder or
underwriter, as the case may be, specifically for use in such registration
statement (or in any preliminary or final prospectus included therein), offering
memorandum or other offering document, or any amendment thereof or supplement
thereto. The foregoing indemnity is in addition to any liability which such
Selling Holder or underwriter, as the case may be, may otherwise have to Next
Level, or controlling persons and the officers, directors, affiliates,
employees, and agents of each of the foregoing; provided, however, that, in the
case of an offering made pursuant to this Agreement with respect to which Next
Level has designated the lead or managing underwriters (or Next Level is
offering securities directly, without an underwriter), this indemnity does not
apply to any loss, liability, cost, claim, or damage arising out of or based
upon any untrue statement or alleged untrue statement or omission or alleged
omission in any preliminary prospectus or offering memorandum if a copy of a
final prospectus or offering memorandum was not sent or given by or on behalf of
any underwriter (or Next Level, as the case may be) to such Person asserting
such loss, liability, cost, claim or damage at or prior to the written
confirmation of the sale of the Registrable Securities as required by the
Securities Act and such untrue statement or omission had been corrected in such
final prospectus or offering memorandum.

            (c) Each party indemnified under paragraph (a) or (b) above shall,
promptly after receipt of notice of a claim or action against such indemnified
party in respect of which indemnity may be sought hereunder, notify the
indemnifying party in writing of the claim or action; provided, that the failure
to notify the indemnifying party shall not relieve it from any liability that it
may have to an indemnified party on account of the indemnity agreement contained
in paragraph (a) or (b) above. If any such claim or action shall be brought
against an indemnified party, and it shall have notified the indemnifying party
thereof, unless in such indemnified party's reasonable judgment a conflict of
interest between such indemnified party and indemnifying parties may exist in
respect of such claim, the indemnifying party shall be entitled to participate
therein, and, to the extent that it wishes, jointly with any other similarly
notified indemnifying party, to assume the defense thereof with counsel
satisfactory to the indemnified party (who shall not, except with the consent of
the indemnified party, be counsel to the indemnifying party); provided that, if
an indemnified party and an indemnifying party shall have conflicting claims or
defenses, the indemnifying party shall not have control of such conflicting
claims or defenses and the indemnified party shall be entitled to appoint
separate counsel for such claims and defenses at the cost and expense of the
indemnifying party. After notice from the indemnifying party to the indemnified
party of its election to assume the defense of such claim or action, the
indemnifying party shall not be liable to the indemnified party under this
Section 2.7 for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. If the indemnifying party does not assume the defense of
such claim or action, it is understood that the indemnifying party shall not, in
connection with any one such claim or action or separate but substantially
similar or related claims or actions in the same jurisdiction arising out of the
same general allegations or circumstances, be liable for the fees and expenses
of more than one separate firm of attorneys (in addition to one separate firm of
local attorneys in each such jurisdiction) at any time for all such indemnified
parties. No indemnifying party shall (i) without the prior written consent of
the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement of any such action effected without its written consent, but if
settled with its written


<PAGE>   16
                                                                              16



consent or if there be a final judgment of the plaintiff in any such action, the
indemnifying party agrees to indemnify and hold harmless any indemnified party
from and against any loss of liability by reason of such settlement or judgment.

            (d) If the indemnification provided for in this Section 2.7 shall
for any reason be unavailable (other than in accordance with its terms) to an
indemnified party in respect of any loss, liability, cost, claim or damage
referred to therein, then each indemnifying party shall, in lieu of indemnifying
such indemnified party, contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, cost, claim or damage in
such proportion as shall be appropriate to reflect the relative fault of the
indemnifying party on the one hand and the indemnified party on the other with
respect to the statements or omissions which resulted in such loss, liability,
cost, claim or damage as well as any other relevant equitable considerations.
The relative fault shall be determined by reference to whether the untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the indemnifying party
on the one hand or the indemnified party on the other, the intent of the parties
and their relative knowledge, access to information and opportunity to correct
or prevent such statement or omission, but not by reference to any indemnified
party's stock ownership in Next Level. The amount paid or payable by an
indemnified party as a result of the loss, cost, claim, damage or liability, or
action in respect thereof, referred to above in this paragraph (d) shall be
deemed to include, for purposes of this paragraph (d), any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

            (e) Indemnification and contribution similar to that specified in
the preceding paragraphs of this Section 2.7 (with appropriate modifications)
shall be given by Next Level, the Selling Holders and underwriters with respect
to any required registration or other qualification of securities under any
state law or regulation or governmental authority.

            (f) The obligations of the parties under this Section 2.7 shall be
in addition to any liability which any party may otherwise have to any other
party.

            2.8 Rule 144 and Form S-3. Commencing 90 days after the date hereof,
Next Level shall use its best efforts to ensure that the conditions to the
availability of Rule 144 set forth in


<PAGE>   17
                                                                              17



paragraph (c) thereof shall be satisfied. Upon the request of any Holder of
Registrable Securities, Next Level will deliver to such Holder a written
statement as to whether it has complied with such requirements. Next Level
further agrees to use its reasonable efforts to cause all conditions to the
availability of Form S-3 (or any successor form) under the Securities Act of the
filing of registration statements under this Agreement to be met as soon as
practicable after the date hereof.

            2.9 Transfer of Registration Rights. Any Holder may transfer all or
any portion of its rights under this Agreement to any transferee of Registrable
Securities owned by such Holder; provided that all or any portion of the rights
under Section 2.1 may only be transferred to a transferee of at least three
percent (3%) of the outstanding shares of Common Stock at the time of transfer
(other than shares held by the General Instrument Entities and Spencer Trask).
Any transfer of registration rights pursuant to this Section 2.9 shall be
effective upon receipt by Next Level of (i) written notice from such Holder
stating the name and address of any transferee and identifying the number of
Registrable Securities with respect to which the rights under this Agreement are
being transferred and the nature of the rights so transferred and (ii) a written
agreement from such transferee to be bound by the terms of this Agreement. The
Holders may exercise their rights hereunder in such priority as they shall agree
upon among themselves.

            2.10 Holdback Agreement. If Next Level effects any registration of
equity securities of Next Level or any securities convertible into or
exchangeable or exercisable for any equity securities of Next Level pursuant to
this Agreement or otherwise in which 20% or more of the securities registered
thereby are Registrable Securities, each Holder agrees not to effect any public
sale or distribution, including any sale under Rule 144, of any equity security
of Next Level or any security convertible into or exchangeable or exercisable
for any equity security of Next Level (otherwise than through the registered
public offering then being made) within 7 days prior to or 90 days (or such
lesser period as the lead or managing underwriters may permit) after the
effective date of the registration statement (or the commencement of the
offering to the public of such Registrable Securities in the case of Rule 415
offerings). Next Level hereby also so agrees; provided, that, subject to Section
2.6(a) hereof, Next Level shall not be so restricted from effecting any public
sale or distribution of any security in connection with any merger, acquisition,
exchange offer, subscription offer, dividend reinvestment plan or stock option
or other executive or employee benefit or compensation plan.

            2.11 Registration of Other Stock. Next Level agrees that it shall
from time to time enter into one or more agreements with General Instrument
and/or the Majority Transferee (as defined in Next Level's certificate of
incorporation), if any, in form and substance reasonably satisfactory to the
parties thereto, granting to General Instrument or the Majority Transferee, as
the case may be, registration rights for the registration of any shares of any
class of capital stock of Next Level other than Common Stock that may hereafter
be owned, directly or indirectly, by General Instrument or the Majority
Transferee, as the case may be, substantially upon the same terms and conditions
as those contained in this Agreement for the benefit of General Instrument.


                                   ARTICLE III
                                  MISCELLANEOUS

            3.1 Limitation of Liability. No party hereto shall be liable
hereunder for any special, indirect, incidental or consequential damages of the
other arising in connection with this Agreement.

            3.2 Affiliates. General Instrument agrees and acknowledges that
General Instrument shall be responsible for the performance by each General
Instrument Entity of the obligations hereunder applicable to such General
Instrument Entity.

            3.3 Amendments. This Agreement may not be amended or terminated
orally, but only by a writing duly executed by or on behalf of each of the
parties hereto. Any such amendment shall be validly and sufficiently authorized
for purposes of this Agreement if it is signed on behalf of the parties hereto
by any of their respective presidents or vice presidents.

            VOTING TRUST AGREEMENT (this "Agreement"), dated as of November __,
1999, by and among GENERAL INSTRUMENT CORPORATION, a Delaware corporation
("Holder"), NEXT LEVEL COMMUNICATIONS, INC., a Delaware corporation ("NLC"), and
CHASEMELLON SHAREHOLDER SERVICES LLC, as Trustee (the "Trustee").

            NLC is authorized to issue 200 million shares of its Common Stock
(the "Voting Stock") and 70 million shares of its Class B Non-Voting Common
Stock;

            Holder owns all of the outstanding shares of common stock of Next
Level Communications, a California corporation ("NLC (CA)");

            On the date hereof, it is contemplated that Next Level
Communications, L.P. (the "Partnership") will merge with and into NLC (the
"Partnership Merger"), upon which NLC (CA) will own all of the outstanding
shares of Class B Non-Voting Common Stock;

            Simultaneously with the Partnership Merger, Holder intends to
contribute an outstanding $75 million principal amount note of the Partnership
(the "Note") to NLC in exchange for shares of Voting Stock, which will be
delivered by NLC directly to the Trustee;

            Holder intends to deposit all of the outstanding shares of common
stock of NLC (CA) with the Trustee immediately following the Partnership Merger;

            Immediately thereafter, NLC (CA) will be merged with and into NLC
(the "NLC Merger"), pursuant to which shares of Class B Non-Voting Common Stock
will be canceled and shares of common stock of NLC (CA) will be converted into
shares of Voting Stock;

            As a result of the foregoing transactions and other transactions
occurring on the date hereof (not including the initial public offering of
shares of Voting Stock to be consummated on or about the business day following
the date hereof), NLC will have issued and outstanding ___ million shares of
Voting Stock, ________ of which will be beneficially owned by Holder and held by
the Trustee, and no shares of Class B Non-Voting Common Stock;

            Holder intends, by entering into this Agreement, to limit its voting
power to the Threshold Percentage (as defined below) of the total voting power
of all of the outstanding shares of Voting Stock; and

            The "Threshold Percentage" shall initially be 49% but may be
decreased to a lower percentage by Holder from time to time by written notice to
the Trustee and NLC;

                                                                               2



            NOW, THEREFORE, in consideration of the mutual agreements, and
subject to all the conditions herein contained, and intending to be legally
bound, the parties hereto agree as follows:

            I.    THE TRUST STOCK

            1.1 Assignment of Trust Stock to Trustee. (a) Effective
simultaneously with the Partnership Merger, Holder hereby transfers, assigns and
delivers to and deposits with the Trustee shares of Voting Stock represented by
Certificate No. 2, which certificate has been directed by Holder to be issued by
NLC in the name of the Trustee or its nominee or agent, receipt of which
certificate the Trustee hereby acknowledges.

            (b) Effective immediately after the Partnership Merger, Holder
hereby also transfers, assigns and delivers to and deposits with the Trustee 33
1/3 shares of common stock of NLC (CA) represented by Certificate No. 3, which
certificate has been duly endorsed by Holder for transfer to the Trustee,
receipt of which certificate the Trustee hereby acknowledges. Holder and NLC
acknowledge and agree that such deposit was made prior to the NLC Merger. Holder
and NLC further acknowledge and agree that Certificate No. 4 for the shares of
Voting Stock to be issued in the NLC Merger in cancellation of the common stock
of NLC (CA) will be issued by NLC in the name of the Trustee or its nominee or
agent. The Voting Stock held by the Trustee pursuant to Sections 1.1(a) and (b)
are herein referred to as the "Initial Trust Stock."

            (c) In addition, Holder may, but shall not be obligated to,
transfer, assign and deliver to and deposit with the Trustee, from time to time,
such number of additional shares of Voting Stock as Holder may elect to be
subject to this Agreement ("Additional Trust Stock," together with the Initial
Trust Stock, the "Trust Stock").

            (d) Holder agrees to execute and deliver to the Trustee, from time
to time, such additional assignments or other instruments of transfer as may be
necessary in the reasonable opinion of the Trustee, NLC or NLC's transfer agent
to confirm and make effective any transfer, assignment, delivery and deposit of
Trust Stock to the Trustee pursuant to this Agreement. The Trustee agrees to
accept each such transfer, assignment, delivery and deposit, and to hold all
Trust Stock in accordance with and subject to this Agreement.

            (e) All certificates for Trust Stock shall show the Trustee or its
nominee or agent as owner of record thereof in its capacity as Trustee under
this Agreement, and the stock transfer books and records of NLC shall reflect
such ownership.

                                                                               3


            1.2 Power of Trustee to Vote Trust Stock. (a) As used herein, (i)
"Holder Voted Shares" shall mean shares of Trust Stock representing up to the
Threshold Percentage of the total voting power of all outstanding shares of
Voting Stock, (ii) "Neutrally Voted Shares" shall mean all shares of Trust Stock
other than the Holder Voted Shares and (iii) "Non-Trust Shares" shall mean all
outstanding shares of Voting Stock other than the Trust Stock.

            (b) At every meeting of the stockholders of NLC of which the
Trustee, its nominee or agent has written notice, the Trustee shall cause the
Holder Voted Shares:

            (i) with respect to any election of directors, to be voted in favor
      of any individuals designated in writing by Holder in such numbers of
      shares as directed in writing by Holder so long as the number of
      individuals designated by Holder and elected to the board of directors
      would not exceed one less than a majority of the board of directors, and

            (ii) with respect to each other matter, to be voted "for," "against"
      or to abstain from voting in such number of shares as directed in writing
      by Holder.

The Trustee shall also cause to be present for purposes of determining the
presence of a quorum at such meeting the Holder Voted Shares which are directed
to be voted pursuant to the immediately preceding sentence (and, if so directed
in writing by Holder, any other Holder Voted Shares). Whenever any consent in
writing of the stockholders of NLC is sought with respect to any action, the
Trustee shall consent thereto with respect to the Holder Voted Shares in such
number of shares as directed in writing by the Holder.

            (c) At every meeting of the stockholders of NLC of which the
Trustee, its nominee or agent has written notice, the Trustee shall cause the
Neutrally Voted Shares:

            (i) with respect to any election of directors, to be voted in favor
      of any individual in the same proportion as all Non-Trust Shares are
      validly voted in favor of such individual.

            (ii) with respect to each other matter, to be voted "for," "against"
      or to abstain from voting in the same proportion as all Non-Trust Shares
      are validly voted "for," "against" or abstain from voting, as the case may
      be, with respect to such matter.

The Trustee shall also cause to be present for purposes of determining the
presence of a quorum at such meeting Neutrally Voted Shares in such number which
is in proportion to the number of Non-Trust Shares which are present at such
meeting in relation


<PAGE>   4
                                                                               4



to the number of outstanding Non-Trust Shares. Whenever any consent in writing
of the stockholders of NLC is sought with respect to any action, the Trustee
shall consent thereto with respect to the Neutrally Voted Shares in such number
which is in proportion to the number of Non-Trust Shares with respect to which a
consent has been delivered in relation to the number of outstanding Non-Trust
Shares.

            (d) NLC agrees that it shall recognize any proxy or written consent
delivered by the Trustee pursuant to this Section 1.2 as effective in the manner
and to the extent provided in this Agreement.

            (e) In causing the Trust Stock to be present at any stockholder
meeting for purposes of determining a quorum or to be voted on at such a meeting
or in consenting to the taking of any action, in each case pursuant to this
Section 1.2, the Trustee shall have no discretion and shall act solely in
accordance with this Agreement.

      1.3 Limitation on Power of Trustee. Except as provided in Section 1.2, the
Trustee shall not possess or be entitled to exercise any right or power with
respect to the Trust Stock and shall act in accordance with written directions
provided by Holder from time to time with respect to the Trust Stock. In
illustration and not in limitation of the foregoing, Holder may from time to
time direct the Trustee to sell, assign or otherwise transfer shares of Trust
Stock, as provided in Section 1.4 below; to tender shares of Trust Stock in
connection with any tender, exchange or other offer and to distribute the
consideration received for such shares in any such tender, exchange or other
offer directly to Holder free of this Trust; to register a dissent from
corporate action and take all steps necessary or desirable to perfect any
dissenters' rights with respect to shares of Trust Stock; and to exercise any
other rights as a stockholder of NLC (other than voting rights to the extent
limited by this Agreement).

            1.4 Transfer of Trust Stock. The Trustee shall, promptly upon
written notice from Holder that Holder has sold, assigned or otherwise
transferred (or that Holder intends to pay a dividend or make a distribution to
its stockholders) some or all of the shares of Trust Stock, deliver to Holder or
to Holder's order a certificate or certificates for such shares (in no event
later than 5 business days after receipt of such notice), endorsed for transfer
in such manner as Holder shall direct; provided, however, that the Trustee shall
have no duty to so deliver any certificate unless, subject to the last sentence
of this Section 1.4, (i) such sale, assignment or other transfer by Holder is a
bona fide sale, assignment or other transfer to a person other than a direct or
indirect subsidiary of General Instrument Corporation, (ii) Holder is not in
default of any of its obligations under this Agreement and (iii) Holder shall
deliver to the Trustee a certificate signed on behalf of Holder

                                                                               5



by a duly authorized officer of Holder, in form and substance reasonably
satisfactory to the Trustee, certifying as to the preceding clauses (i) and
(ii). Any consideration received or to be received by Holder in connection with
any such sale, assignment or other transfer shall not be subject to this
Agreement and if received by the Trustee shall promptly be distributed to Holder
in accordance with Section 1.5. In the event of any sale, assignment or other
transfer by Holder of any Trust Stock which satisfies the conditions set forth
in this Section 1.4, the shares of Trust Stock so sold, assigned or otherwise
transferred shall thereafter not be subject to this Agreement in any respect and
shall cease to be Trust Stock. Nothing in this Agreement shall prohibit the
sale, assignment or other transfer of any shares of Trust Stock to any person so
long as such person agrees that such shares will continue to be Trust Stock and
remain subject to this Agreement.

            1.5 Trustee to Receive And Distribute Dividends. The Trustee shall
receive all dividends paid upon the Trust Stock in any manner (other than in
shares of Voting Stock), including, without limitation, cash, and shall promptly
pay such dividends to Holder. Any and all shares of Voting Stock received by the
Trustee as a dividend or distribution on, or upon any split-up or subdivision
of, any of the Trust Stock, shall be held by the Trustee as Trust Stock.


            II. THE TRUSTEE

Agreement, and no implied covenants or obligations shall be read into this
Agreement against the Trustee.


            (b) In the absence of bad faith or gross negligence on its part, as
determined by a court of competent jurisdiction, the Trustee shall not be liable
for any action taken, suffered, or omitted or for any error of judgment made by
it in the performance of its duties under this Agreement. The Trustee shall not
be liable for any error of judgment made in good faith unless the Trustee shall
have been grossly negligent in ascertaining the pertinent facts. In no event
shall the Trustee be liable for special, indirect or consequential damages or
loss

any of the provisions of this Agreement (including the reasonable compensation,
expenses and disbursements of its counsel and all persons not regularly in its

                                   ARTICLE II
                                     OPTIONS

            2.1 Options. (a) Next Level hereby grants to General Instrument, on
the terms and conditions set forth herein, a continuing right (the "Common Stock
Option") to purchase from Next Level, at the times set forth herein, the number
of shares of Common Stock provided in the first sentence of Section 2.3. The
Common Stock Option shall be assignable, in whole or in part and from time to
time, by General Instrument to any General Instrument Entity. The exercise price
for the shares of Common Stock purchased pursuant to the Common Stock Option
shall be the Market Price of the Common Stock as of the date of first delivery
of notice of exercise of the Common Stock Option by General Instrument (or its
permitted assignee hereunder) to Next Level.

            (b) The provisions of Section 2.1(a) hereof notwithstanding, the
Common Stock Option granted pursuant to Section 2.1(a) shall not apply and shall
not be exercisable in connection with the issuance by Next Level of any shares
of Common Stock pursuant to any stock option or other executive or employee
benefit or compensation plan maintained by Next Level, so long as, from and
after the date hereof and prior to the issuance of such shares, Next Level has
repurchased from stockholders and not subsequently reissued a number of shares
equal or greater to the number of shares to be issued in any such issuance.

            (c) Next Level hereby grants to General Instrument, on the terms and
conditions set forth herein, a continuing right (the "Nonvoting Stock Option"
and, together with the Common Stock Option, the "Options") to purchase from Next
Level, at the times set forth herein, such number of shares of Nonvoting Stock
as is necessary to allow the General Instrument Entities to own 80 percent of
each class of outstanding Nonvoting Stock. The Nonvoting Stock Option shall be
assignable, in whole or in part and from time to time, by General Instrument to
any General Instrument Entity. The exercise price for the shares of Nonvoting
Stock purchased pursuant to the Nonvoting Stock Option shall be the price at
which such Nonvoting Stock is then being sold to third parties, or, if no
Nonvoting Stock is being sold, the fair market value thereof as determined in
good faith by the Board of Directors of Next Level.

            2.2 Notice. At least 20 business days prior to the issuance of any
shares of Common Stock (other than (i) in connection with the Initial Public
Offering, including the full exercise of all underwriters' over-allotment
options granted in connection therewith, (ii) issuances of Common Stock to any


<PAGE>   5
                                                                               5



General Instrument Entity and (iii) pursuant to any stock option or other
executive or employee benefit or compensation plan maintained by Next Level) or
the first date on which any other event could occur that, in the absence of a
full or partial exercise of the Common Stock Option, would result in any
reduction in the Ownership Percentage, Next Level will notify General Instrument
in writing (a "Common Stock Option Notice") of any plans it has to issue such
shares or the date on which such event could first occur; provided that, within
five business days after the end of each fiscal quarter, Next Level will notify
General Instrument in writing of the number of shares issued in such quarter
pursuant to any stock option or other executive or employee benefit or
compensation plan maintained by Next Level (the "Quarterly Plan Notice"). At
least 20 business days prior to the issuance of any shares of Nonvoting Stock
(other than issuances of Nonvoting Stock to any General Instrument Entity) or
the first date on which any event could occur that, in the absence of a full or
partial exercise of the Nonvoting Stock Option, would result in the General
Instrument Entities owning less than 80 percent of each class of outstanding
Nonvoting Stock, Next Level will notify General Instrument in writing (a
"Nonvoting Stock Option Notice" and, together with a Common Stock Option Notice,
an "Option Notice") of any plans it has to issue such shares or the date on
which such event could first occur. Each Option Notice must specify the date on
which Next Level intends to issue such additional shares or on which such event
could first occur (such issuance or event being referred to herein as an
"Issuance Event" and the date of such issuance or event as an "Issuance Event
Date"), the number of shares Next Level intends to issue or may issue and the
other terms and conditions of such Issuance Event.

            2.3 Option Exercise and Payment. The Common Stock Option may be
exercised by General Instrument (or any General Instrument Entity to which all
or any part of the Common Stock Option has been assigned) for a number of shares
equal to or less than the number of shares that are necessary for the General
Instrument Entities to maintain, in the aggregate, the Ownership Percentage
prior to giving effect to the applicable Issuance Event or any issuance by Next
Level of any shares of Common Stock pursuant to any stock option or other
executive or employee benefit or compensation plan maintained by Next Level
prior to the applicable date of exercise of the Common Stock Option (with
respect to which the Common Stock Option has not been previously exercised). The
Nonvoting Stock Option may be exercised by General Instrument (or any General
Instrument Entity to which all or any part of the Nonvoting Stock Option has
been assigned) for a number of shares equal to or less than the number of shares
that are necessary for the General Instrument Entities to own, in the aggregate,
80 percent of each class of outstanding Nonvoting Stock. Each Option may be
exercised at any time after receipt of


<PAGE>   6
                                                                               6




an applicable Option Notice and prior to the applicable Issuance Event Date (or
within 20 business days after the delivery of the Quarterly Plan Notice) by the
delivery to Next Level of a written notice to such effect (an "Exercise Notice")
specifying (i) the number of shares of Common Stock or Nonvoting Stock, as the
case may be, to be purchased by General Instrument, or any of the General
Instrument Entities and (ii) a calculation of the exercise price for such
shares. Upon any such exercise of either Option, Next Level will, prior to the
applicable Issuance Event Date or, in the case of an exercise following a
Quarterly Plan Notice, within 10 business days after delivery to Next Level of
an Exercise Notice, deliver to General Instrument (or any General Instrument
Entity designated by General Instrument), against payment therefor, certificates
(issued in the name of General Instrument or its permitted assignee hereunder or
as directed by General Instrument) representing the shares of Common Stock or
Nonvoting Stock, as the case may be, being purchased upon such exercise. Payment
for such shares shall be made by wire transfer or intrabank transfer of
immediately-available funds to such account as shall be specified by Next Level,
for the full purchase price for such shares.


            2.4 Effect of Failure to Exercise. Except as provided in Section
2.6, any failure by General Instrument to exercise either Option, or any
exercise for less than all shares purchasable under either Option, in connection
with any particular Issuance Event shall not affect General Instrument's right
to exercise the relevant Option in connection with any subsequent Issuance
Event.

            2.5 Initial Public Offering. Notwithstanding the foregoing, General
Instrument shall not be entitled to exercise the Common Stock Option in
connection with the Initial Public Offering.

            2.6 Termination of Options. The Options shall terminate upon the
occurrence of any Issuance Event that, after considering General Instrument's
response thereto and to any other Issuance Events, results in the Ownership
Percentage being less than 30%, other than any Issuance Event in violation of

                         CERTAIN COVENANT AND AGREEMENTS

            3.1 No Violations. (a) For so long as the Ownership Percentage is
greater than 50%, Next Level covenants and agrees that it will not take any
action or enter into any commitment or agreement which may reasonably be
anticipated to result, with or without notice and with or without lapse of time
or otherwise, in a contravention or event of default by any General Instrument
Entity of (i) any provisions of applicable law or regulation, including but not
limited to provisions pertaining to the Internal Revenue Code of 1986, as
amended, or the Employee Retirement Income Security Act of 1974, as amended,
(ii) any provision of the certificate of incorporation or by-laws of any General
Instrument Entity, (iii) any credit agreement or other material instrument
binding upon any General Instrument Entity or (iv) any judgment, order or decree
of any governmental body, agency or court having jurisdiction over any General
Instrument Entity or any of its assets.

            (b) Next Level and General Instrument agree to provide to the other
any information and documentation requested by the other for the purpose of
evaluating and ensuring compliance with Section 3.1(a) hereof.

            (c) Notwithstanding the foregoing Sections 3.1(a) and 3.1(b),
nothing in this Agreement is intended to limit or restrict in any way any
General Instrument Entity's rights as a stockholder of Next Level.

            3.2 Tax Matters. (a) For all taxable periods ending on or before the
date hereof, General Instrument shall timely prepare and file with the
appropriate tax authority all returns with respect to Taxes for Next Level
California and shall pay all Taxes shown due on such returns (other than any
Taxes attributable to any action taken after the closing of the Next Level
California Merger by Next Level or any of its Affiliates or any transferee of
Next Level or any of its Affiliates), and such returns shall be prepared
consistently with past practices. Both General Instrument and Next Level shall
prepare any Tax returns relating to General Instrument and Next Level,
respectively, in a manner consistent with the positions taken on such returns.

            (b) In the case of an audit or judicial proceeding that relates to
Next Level California or Next Level for periods ending on or before the date
hereof, General Instrument shall have the sole right to control the conduct of
such audit or proceeding. Next Level shall not enter into any settlement or
closing or other agreement with respect thereto without the consent of General
Instrument.

                                                                               8



            (c) After the date hereof, Next Level shall notify General
Instrument in writing within 10 days following the receipt of written notice of
the commencement of any Tax audit or administrative or judicial proceeding or of
any demand or claim on Next Level. Such notice shall contain factual information
describing the asserted Tax liability in reasonable detail and shall include
copies of any notice or other document received from any taxing authority in
respect of any such asserted tax liability.

            (d) In the case of an audit or administrative or judicial proceeding
that relates to periods ending after the date hereof, so long as General
Instrument owns at least 30% of the number of outstanding shares of common stock
of Next Level, General Instrument and Next Level shall jointly control the
defense and settlement of any such contest and each party shall cooperate with
the other party at its own expense and there shall be no settlement or closing
or other agreement with respect thereto without the consent of the other party,
which consent shall not be unreasonably withheld and, if Next Level does not
assume the defense of any such audit or proceeding, General Instrument may
defend the same in such manner as it may deem appropriate, including but not
limited to, settling such audit or proceeding.

            (e) Next Level shall prepare and file any Tax returns for all
taxable periods that end after the date hereof and Taxes shown to be due on such
returns. Such returns shall be prepared in a manner consistent with the prior
practice of Next Level California and, so long as General Instrument owns at
least 30% of the number of outstanding shares of common stock of Next Level,
Next Level shall deliver to General Instrument such returns at least 15 business
days before such return is due to be filed (taking into account any extensions
of time to file such return that have been properly obtained) for General
Instrument's review and comment.

            (f) General Instrument shall have the right to object to any items
set forth on any return prepared by Next Level within 7 days of the delivery of
a particular return under section 3.2(e) but only if there is no reasonable
basis for the position taken with respect to an item or items set forth on such
return or such return is otherwise inaccurate. In the event of such objection,
the parties shall attempt in good faith to resolve the dispute and any
resolution shall be final and binding on them. If the parties cannot resolve any
such dispute within 7 days of such delivery, the items remaining in dispute
shall be submitted to an independent accounting firm of international reputation
selected by, and mutually acceptable to, General Instrument and Next Level and
which expense shall be shared


<PAGE>   9
                                                                               9



equally between General Instrument and Next Level. The independent accounting
firm so selected shall determine the proper amounts for the items remaining in
dispute and General Instrument and Next Level shall be bound by the
determination by the independent accounting firm absent manifest error. The
independent accounting firm shall make any such determination within 7 days
after submission of the remaining disputed items. If a return is due before the
date a disputed item is resolved hereunder, it shall be filed as prepared and
resolved items shall be reflected on an amended return.

            (g) General Instrument and Next Level each shall provide the other
party with such cooperation and information as such other party may reasonably
request in filing any Tax return, amended return or claim for refund,
determining a liability for taxes or a right to refund of Taxes or participating
in or conducting any audit or other proceeding in respect of Taxes. Such
cooperation and information shall include providing copies of relevant tax
returns or portions thereof, together with accompanying schedules and related
work papers and documents relating to rulings or other determinations by taxing
authorities. Next Level shall retain all returns, schedules and work papers and
all material records or other documents relating to Tax matters until the later
of (i) the expiration of the statute of limitations of the taxable periods to
which such returns and other documents relate or (ii) five years following the
date for such returns provided, however, that Next Level shall not dispose of
any such materials if at least 90 business days before the later of the end of
either of the periods described in clauses (i) or (ii) General Instrument has
notified Next Level of its desire to review such material in which case General
Instrument shall be given an opportunity to remove and retain all or any part of
such materials.

            3.3 Rohnert Park Lease. (a) Next Level shall sublease the Rohnert
Park facility currently occupied by Next Level (the "Facility") from General
Instrument. Until December 31, 1999, sublease payments shall be in an amount
equal to the amount payable by General Instrument pursuant to the lease and
financing documents entered into under the Participation Agreement dated as of
June 30, 1997 (the "Lease and Finance Agreements"), and Next Level shall make
such payments directly to the parties contemplated by the Lease and Finance
Agreements or as otherwise directed by General Instrument. Thereafter, Next
Level shall pay directly to General Instrument the greater of a fair market
value rent on the Facility or the amounts payable by General Instrument pursuant
to the Lease and Finance Agreements.

            (b) Next Level shall have an option to require General Instrument to
exercise its purchase option under the Lease and

                                                                              10



Finance Agreements for the Facility and to designate Next Level as the
purchaser. The purchase price to be paid by Next Level to General Instrument
shall be equal to (i) until December 31, 1999, the amount of indebtedness
outstanding under the loans and lessor contributions obtained to facilitate the
purchase and construction of the Facility and sufficient to permit the
acquisition of the Facility and meet the purchase requirements set out in the
Lease and Finance Agreements and obtain a complete release of General Instrument
as a guarantor under the Lease and Finance Agreements and (ii) thereafter, the
greater of the amount determined under clause (i) above or the fair market value
of the Facility.

            (c) For purposes of Section 3.3(a) or (b), "fair market value" shall
be determined in the following manner: General Instrument and Next Level shall
endeavor in good faith to reach a mutual agreement as to such amount for a
period of ten (10) business days, and if they cannot agree within ten (10)
business days, then such amount shall be determined by an independent third
party appraiser selected by General Instrument and reasonably acceptable to Next
Level. The fees and expenses of such appraiser shall be borne equally by General
Instrument and Next Level.

            3.4 Board of Directors. Upon the termination of the Voting Trust
Agreement among General Instrument, Next Level and ChaseMellon Shareholder
Services, LLC (and if at such time General Instrument holds at least a majority
of the outstanding shares of Common Stock and gives Next Level reasonable
advance notice thereof), Next Level and its board of directors shall take all
actions necessary (without requiring any action on the part of any stockholder
of Next Level) to appoint on the date of such termination any number of
additional directors nominated by General Instrument. Prior to such termination,
Next level will not increase the size of its board of directors without the
prior written consent of General Instrument.

            3.5 Indemnification. Next Level shall indemnify and hold harmless
each of the General Instrument Entities and each of their respective officers,
directors, employees and agents (collectively, the "Indemnified Parties"),
against any and all costs and expenses from third party claims (including,
without limitation, attorneys' fees, interest, penalties and costs of
investigation, preparation or defense), judgments, fines, losses, claims,
damages, liabilities, demands, actions, causes of action, assessments and
amounts paid in settlement (collectively, "Losses"), including, without

                                                                              11



action, suit, proceeding or investigation, whether civil, criminal,
administrative, investigative or other (collectively, the "Actions"), based on,
arising out of, pertaining to or in connection with (a) any activities or
omissions of the Next Level Entities (and their predecessors) or any of their
officers, directors, employees, affiliates (other than the General Instrument
Entities) or agents or (b) any breach by the Next Level Entities of this
Agreement. This indemnity shall be applicable whether or not such Actions or the
facts or transactions giving rise to such Actions arose prior to, on or
subsequent to the date hereof. Next Level shall, if and to the extent requested
in writing by the Indemnified Parties, participate in the defense of any such
Action with counsel satisfactory to General Instrument; provided that, if any
Indemnified Party determines that such Indemnified Party has a conflict of
interest with Next Level or any other Indemnified Party, such Indemnified Party
shall have the right to employ in its sole discretion separate counsel to
represent such Indemnified Party. Next Level shall pay all fees and expenses of
such separate counsel. Next Level shall not without the prior written consent of
the Indemnified Parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened Action in respect of which
indemnification may be sought hereunder (whether or not the Indemnified Parties
are actual or potential parties to such Action) unless such settlement,
compromise or consent includes an unconditional release of each Indemnified
Party from all liability arising out of such Action. The provisions of this
Section are for the benefit of, and are intended to create third party
beneficiary rights in favor of, each of the Indemnified Parties.

            3.6 Guaranty. Next Level shall obtain a complete release of General
Instrument from its guaranty of Next Level's contract with Bell Atlantic as
promptly as practicable after the date hereof and in any event not later than
December 31, 1999.

            3.7 Confidentiality. Except as required by law, regulation or legal
or judicial process, General Instrument agrees that neither it nor any General
Instrument Entity nor any of their respective directors, officers, advisors,
agents or employees will without the prior written consent of Next Level
disclose to any other Person any material, non-public information concerning the
business or affairs of Next Level acquired from any director, officer, advisor,
agent or employee of Next Level (including any director, officer, advisor, agent
or employee of Next Level who is also a director, officer, advisor, agent or
employee of General Instrument).

consistent with the requirements for a waiver of compliance as described above,
with appropriate notice provided in accordance with this Agreement.

consents and permits required by any law or regulation for the performance of

reorganization) of substantially all of NLC's or GI's business or a substantial
part of its business segment which exploits this rights granted under this

parties.

      11.4 CHANGE ORDER

            11.4.1 NYNEX may at any time upon fifteen (15) days written notice
to Supplier, by written order, make any change within the scope of this
Agreement or any Order(s), including, without limitation, the addition or
deletion of System(s), Product, Material, Software covered, the Service(s) to be
performed, the time and/or place of performance, delivery or installation
thereof. Any such order shall be specifically identified as a Change Order
pursuant to this Article. In the event NYNEX desires to make a change, NYNEX
shall request Supplier to provide a written proposal stating the additional
requirements or reduction of existing requirements and the cost and schedule
implications incident thereto. SUPPLIER agrees that the cost to NYNEX of the
change shall be determined in accordance with the terms of Appendix D hereof,
entitled CHANGES IN SCOPE. If NYNEX is in agreement with the terms, conditions
and charges specified in the proposal, NYNEX will issue a Change Order pursuant
to this Agreement. In the event that the Change Order is issued at least fifteen
(15) days prior to the scheduled delivery date, the change(s) shall be
accomplished without affecting the original delivery date; unless otherwise
specified in the terms of an agreed upon Change Order if the Change Order is
issued less than fifteenth (15) days from the scheduled delivery date, the
delivery date may be subject to change and Supplier will identify, upon receipt
of the Change Order, whether, and to what extent, any change in delivery date
will occur. All Services and Materials covered hereunder shall be performed in
accordance with this Agreement and such changes thereto as are subsequently
authorized by a written Change Order issued by NYNEX. Nothing in this clause
shall excuse the Supplier from proceeding with the Agreement as changed.

            11.4.2 Before the issuance of a Change Order under this Agreement,
NYNEX may request SUPPLIER's written agreement as to the maximum (in case of an
increase) or minimum (in case of a decrease) adjustments to be made in the price
and/or in the time of performance, by reason of the change. NYNEX may also
request an agreement limiting the adjustments to any other provisions of the
Agreement which may be subject to equitable adjustment by reason of the change.
Any such written agreement shall then be cited in the Change Order, and upon its
issuance shall be deemed to become part of this Agreement. In making equitable
adjustments pursuant to this clause, in no event shall the definitive adjustment
exceed the maximum or be less than the minimum price and/or time of performance
adjustments so established, nor otherwise be inconsistent with other adjustment
limitations so established. Except with respect to such limitations, nothing
contained in this paragraph (2) shall affect the SUPPLIER's rights to equitable
adjustment by reason of the change pursuant to this clause.

            11.4.3 Unless expressly stipulated elsewhere in this Agreement as
being excepted from this provision, wherever this Agreement provides for
submittal of designs, data including Software, elements, procedures, or other
items for approval of NYNEX, such approvals shall not be construed as a complete
check as to the adequacy of said design, procedure, practice or item, nor as a
agreement that the design, procedure, practice or items will meet the
requirements of the Order or Change Order. Such approvals are for the purpose of
ensuring NYNEX's knowledge of the SUPPLIER's plans and progress and will
indicate only that the SUPPLIER's general approach toward meeting contractual
requirements is satisfactory. Such approvals shall in no way relieve the
Supplier of the responsibility for any error or deficiency which may exist in
the submitted design, procedure, or other items, as the

may from time to time render assistance or give technical advice to, or effect
an exchange of information with, SUPPLIER's personnel in a liaison effort
concerning the System, Products, Material, Software or Services to be furnished
hereunder. However, such exchange of information or advise shall not vest
Supplier with the authority to change the Material, Software or Service(s)
hereunder or the provisions of the Agreement, and no change in the Material or
Service(s) or the provisions of the Agreement shall be binding upon NYNEX unless
incorporated as a change in accordance with Section 11.4 hereof. Only NYNEX, is

Order is delivered to the Supplier, and for any further period to which the
parties may agree not to exceed [ * ]. Any such order shall be specifically
identified as a Stop Work Order issued pursuant to this clause and shall
automatically extend the time of performance or the delivery date of such Work
for a period equal to the period of the Stop Work Order.

            11.5.2 Upon receipt of such an order, the Supplier shall forthwith
comply with its terms and take all reasonable steps to minimize the incurrence
of costs allocable to the Work covered by the order during the period of work
stoppage. Within a period of [ * ] after a Stop Work Order is delivered to the
Supplier, or within any extension of that period to which the parties shall have
agreed, NYNEX shall either: (i) cancel the Stop Work Order, or (ii) terminate
the Work covered by such order as provided in Article 7 hereof, entitled
TERMINATION.

            11.5.3 If a Stop Work Order issued under this clause is canceled or
the period of the order or any extension thereof expires, the Supplier shall
resume Work. An equitable adjustment shall be made in delivery schedule or the
period of performance and in any other provisions of the Agreement that may be
affected, and the Agreement shall be modified in writing accordingly, if,

            (i) the Stop Work Order results in an increase in the time required
for, or in the SUPPLIER's cost properly allocable to the performance of any part
of this Agreement, and

            (ii) the Supplier asserts a claim for such adjustment within [ * ],

                  assistance is required to correct a problem or defect under

include the implementation and execution of the accepted remedy or corrective
action to resolve the stated problem, or the date when the accepted solution
will be completed.

         In the event that a NYNEX EC is marked "SERVICE EMERGENCY," then
SUPPLIER agrees to exert effort which goes beyond that which is customarily
provided to resolve the EC. Such effort will be consistent with the level of
effort SUPPLIER will furnish to support NYNEX and its AFFILIATES under the
clauses hereof entitled "REPAIRS AND REPLACEMENT" and "EXTRAORDINARY SUPPORT."

         In the event the SUPPLIER anticipates that the solution to the EC will
exceed thirty (30) days, then SUPPLIER shall issue bi-weekly EC Interim Reports
to NYNEX, reporting actions taken and progress made during the reporting period.
In addition, such reports will indicate the date by which SUPPLIER anticipates
that the ongoing EC study will be successfully concluded. This requirement
modifies GR-230-CORE, Section 2.3.2.2.

         SUPPLIER shall create and maintain a tracking system that records and
summarizes all events surrounding all ECs submitted by NYNEX. SUPPLIER shall
also provide NYNEX with on-going reports at monthly intervals as to what
manifested the EC, what remedial actions were made by SUPPLIER as a result of
the EC and what was the result of those remedial actions. The overall progress
and performance results shall be reviewed by NYNEX and SUPPLIER to evaluate the
overall quality of the process.

         Upon acceptance of SUPPLIER's resolution by NYNEX, SUPPLIER shall
implement necessary changes within thirty (30) days.

         SUPPLIER shall be responsible for reimbursement or credit to NYNEX
and/or its AFFILIATE for any mutually agreed to substantiated claim resulting
from an EC, and such agreement shall not be unreasonably withheld or delayed by
either party. Any such claim shall be resolved within thirty (30) days after
resolution of the EC upon which it is based in accordance with Section 10.7
hereof, entitled PERFORMANCE COMPENSATION PAYMENTS.

         If NYNEX or its AFFILIATE disagree with SUPPLIER on the implementation
schedule and/or resolution of an EC, NYNEX or its AFFILIATE shall have the right
to escalate the matter for review on the implementation schedule, validity of
the complaint, and/or resolution to higher management in accordance with Article
31 hereof, entitled ALTERNATE DISPUTE RESOLUTION.

MOP shall be provided to NYNEX with the PCN.

         Any related Engineering Complaint Number shall be included on the PCN
form.

         If NYNEX or its AFFILIATE disagrees with the nature of, or with the
classification which SUPPLIER assigns to, a change in MATERIAL or SOFTWARE,
NYNEX or its AFFILIATES shall have the right to escalate the matter for review,
reclassification, and resolution to higher levels of management in accordance
with the Alternate Dispute Resolution clause of this AGREEMENT.

         SUPPLIER shall provide all changed MATERIAL, SOFTWARE, and
DOCUMENTATION for Class A and AC changes for a period of twenty (20) years from
the date of last shipment of the affected MATERIAL or SOFTWARE, at no charge to
NYNEX or its AFFILIATES. Where SUPPLIER installed the MATERIAL or SOFTWARE
subject to the Class A and AC change, SUPPLIER will supply such change MATERIAL,
SOFTWARE, and installation labor without charge. Where NYNEX, its AFFILIATE
and/or AFFILIATE's agent has installed MATERIAL or SOFTWARE, SUPPLIER will
supply such change to MATERIAL and/or SOFTWARE without charge and will reimburse

corrective action for a change during a period of twenty (20) years from the
date of last shipment of the MATERIAL or SOFTWARE. SUPPLIER shall supply
relevant DOCUMENTATION to NYNEX for all Class A and AC changes.

         DOCUMENTATION changes, required to satisfy SUPPLIER's obligations to
provide Class A and AC changes to MATERIAL or SOFTWARE as specified herein,
shall be provided by SUPPLIER at no charge to NYNEX or its AFFILIATES.

         For those changes classified as "B" or "D", SUPPLIER shall notify NYNEX
in writing one hundred and twenty (120) days prior to the effective date of such
change to be made in the MATERIAL or SOFTWARE furnished under an order.

         For Class B changes, SUPPLIER shall first notify NYNEX of the exact
nature of the change. Details of the proposed implementation procedure for
MATERIAL or SOFTWARE which is being or will be manufactured shall be discussed
with NYNEX or its AFFILIATES within the notification time periods stated in the
first section above. NYNEX or its AFFILIATE shall, at its option, determine if
MATERIAL or SOFTWARE previously shipped shall be replaced or modified. Should
such replacement or modifications be deemed necessary, SUPPLIER shall make
arrangements for the necessary MATERIAL, SOFTWARE, DOCUMENTATION or RELATED
DOCUMENTATION replacement or modification at prices and schedules to be mutually
agreed upon with NYNEX or its AFFILIATES prior to implementation.

         In the event that NYNEX does not desire any such change, NYNEX shall
notify SUPPLIER in writing within sixty (60) days from the date of receipt of
notification and SUPPLIER shall not furnish any such changed MATERIAL or
SOFTWARE to NYNEX pursuant to any Orders. NYNEX may extend the sixty (60) day
period if NYNEX is unable to respond within such period.

                  by the warranty is entirely independent of acceptance,
                  including NYNEX's rights and remedies in acceptance, and is
                  not intended to nor shall it be construed as in any way
                  precluding, limiting or otherwise affecting NYNEX's acceptance
                  rights which shall be and remain as set forth in Section 12.13
                  hereof, entitled ACCEPTANCE.

         c)       In all instances where the repair or replacement of System(s),
                  Product, Material, Software is not completed within [ * ] of
                  Supplier's receipt of notification of the defect, the warranty
                  period shall be extended for a period equivalent to the time
                  required by Supplier to complete the repair or replacement.

      (A)   In addition to the foregoing Sections 13.1 through 13.5 and 13.7,
            SUPPLIER warrants to NYNEX and its AFFILIATES that it has the right
            to grant the licenses for SOFTWARE ordered hereunder, and that
            SOFTWARE ordered under this AGREEMENT shall properly function in the
            SYSTEM environment, and shall conform, function and perform in
            accordance with all of SUPPLIER's published software specifications
            and with the SPECIFICATIONS set forth in Appendix A hereof, entitled
            SCOPE OF WORK including all subsequent changes and modifications

            characteristics, documentation, compatibility, and modularity.

      (B)   The warranty shall apply to all software releases, upgrades,
            enhancements, fixes, modifications and the like as well as third
            party software and SUPPLIER's firmware.

      (C)   In the event the SOFTWARE fails to perform as described in
            Subsection (A) of this Section 13.8, SUPPLIER shall promptly correct
            or replace the SOFTWARE.

      (D)   The transportation expense associated with returning SOFTWARE to and
            from SUPPLIER shall be borne by SUPPLIER.

      (E)   SUPPLIER shall notify NYNEX and its AFFILIATES of defects in
            SUPPLIER's SOFTWARE of which SUPPLIER becomes aware and SUPPLIER

            during the period needed to correct the defect and upon correction
            shall restart for the remaining warranty period or [ * ] whichever
            is greater.

      (F)   SOFTWARE Release Warranty. SUPPLIER hereby represents and warrants
            to NYNEX that, for a period of [ * ] following the ACCEPTANCE DATE
            for such any SYSTEM: (i) No release by SUPPLIER of any operating
            SOFTWARE for any SYSTEM purchased by or provided to NYNEX pursuant
            to this Agreement shall eliminate, reduce, or degrade the
            performance capabilities of the SYSTEM from the corresponding level
            of performance at the ACCEPTANCE DATE for the SYSTEM; and (ii)
            Applications SOFTWARE will function on such SYSTEM purchased by or
            otherwise provided to NYNEX pursuant to this Agreement, unless
            specifically noted in the appropriate Order; (iii) SUPPLIER shall
            maintain the previous two (2) release levels of any SOFTWARE, or all
            levels released over the previous [ * ], whichever is longer.

      (G)   SUPPLIER also shall perform a Post Mortem analysis after each major
            SOFTWARE release. Such analysis should determine which development
            stage activities were accomplished smoothly and which activities
            contributed to problems that effected quality or scheduling. Results
            of the analysis should yield documented process improvement plans
            which will be implemented before development of the next release
            begins.

      (H)   Year 2000 - Representation and Warranty (SOFTWARE) SUPPLIER
            represents and warrants that all SOFTWARE Deliverables delivered
            hereunder shall record, store, process, and present calendar dates
            falling on or after January 1, 2000, in the same manner, and with
            the same functionality, as such SOFTWARE record, store, process and
            present calendar dates falling on or before December 31, 1999.
            SUPPLIER further represents and warrants that in all other respects
            such SOFTWARE shall not in any way lose functionality or degrade in
            performance as a consequence of such SOFTWARE operating at a date
            later than December 31, 1999. Without limitation of the foregoing,
            SUPPLIER's representative will consult with NYNEX' or AFFILIATE's
            designated representative for century date change requirements, to
            ensure that such SOFTWARE Deliverables will lose no functionality
            with respect to the introduction of records containing dates falling
            on or after January 1, 2000, and to use its best efforts to ensure
            that such SOFTWARE Deliverable will be interoperable with other
            SOFTWARE used by NYNEX or AFFILIATE which may deliver records to
            such SOFTWARE Deliverable, receive records from such SOFTWARE
            Deliverable, or interact with such SOFTWARE Deliverable in the
            course of processing data.

            (SYSTEMS) SUPPLIER represents and warrants that all SYSTEMS
            delivered hereunder will record, store, process, and present
            calendar dates falling on or after January 1, 2000, and with the
            same functionality, as such SYSTEMS record, store, process and
            present calendar dates falling on or before December 31, 1999.
            SUPPLIER further represents and warrants that in all other respects
            such SYSTEMS shall not in any way lose functionality or degrade in
            performance as a consequence of such SYSTEMS operating at a date
            later than December 31, 1999. Without limitation of the foregoing,
            SUPPLIER's representative will consult with NYNEX' or AFFILIATE's
            designated representative for century date change requirements, to
            ensure that such SYSTEMS will lose no functionality nor will they
            degrade in performance with respect to the introduction of records
            containing dates falling on or after January 1, 2000, and to use its
            best efforts to ensure that such SYSTEMS will be interoperable with
            other SYSTEMS used by NYNEX or its AFFILIATE which may deliver
            records to such SYSTEMS, receive records from such SYSTEMS, or
            interact with such SYSTEMS, in the course of processing data.

            Notwithstanding the foregoing, Supplier shall have no responsibility
            for any loss of functionality or degradation or failure to record,
            store, process or present calendar dates falling on or after January
            1, 2000 caused by the failure to so perform of any software or
            systems, other than Supplier's, used by NYNEX or any of its
            Affiliates or any other supplier.

      13.9 ESCROW In order to protect the rights of NYNEX, SUPPLIER shall keep
and maintain current a copy of the SOURCE CODE and Related Documentation for any
SOFTWARE licensed by SUPPLIER to NYNEX in escrow with a commercial escrow agent
selected by NYNEX, pursuant to an escrow agreement by and among SUPPLIER, NYNEX,

pursuant to this Agreement or if SUPPLIER fails to maintain the escrow as agreed
herein.

The Source Code Escrow agreement shall include, but not be limited to,
conditions defined as "Escrow Release Events" upon which source code shall be
released to NYNEX, temporarily or permanently if one or more of, the following
events occur:

a.    permanently, if SUPPLIER becomes insolvent or admits insolvency or admits
      a general inability to pay debts as they become due;

b.    permanently, if SUPPLIER files a petition for protection under the
      Bankruptcy code of the United States, or an involuntary petition is filed
      against the SUPPLIER and is not dismissed within sixty (60) days;

c.    permanently, if control of SUPPLIER is acquired by a competitor of NYNEX
      and it is determined by NYNEX that there is a threat to its interest or
      inadequate safeguards exist resulting from the transfer of control;

d.    temporarily, if SUPPLIER fails to provide technical support during any
      emergency or out-of-service condition. NYNEX shall only use source code
      released during this event for the purpose of placing the SYSTEM back into
      operation.

[ * ] shall pay all costs of providing and maintaining the SOURCE CODE in
escrow, including the fees of the escrow agent. NYNEX shall have the right at
any time to verify that the copy of the SOURCE CODE placed in escrow shall be
reproduced and maintained on machine readable media compatible with SUPPLIER's
Equipment and shall be accompanied by full documentation thereof. When a change
is made to the SOURCE CODE by or on behalf of SUPPLIER during the term of the
escrow agreement, the revised SOURCE CODE, including the change, shall be
delivered to the escrow agent not later than [ * ] business days after the
change  is affected by or on behalf of SUPPLIER. Copies of the revised SOURCE
CODE and the SOURCE CODE prior to the then-latest revision shall be maintained
in escrow as provided hereunder.

      13.10 ILLICIT CODE SUPPLIER warrants (a) unless authorized in writing by
NYNEX or (b) necessary to perform valid duties under this Agreement, any
SOFTWARE provided to NYNEX by SUPPLIER for use by SUPPLIER or NYNEX shall: (a)
contain no hidden files; (b) not replicate, transmit, or activate itself without
control of a person operating computing equipment on which it resides; (c) not
alter, damage, or erase any data or computer programs without control of a
person operating the computing equipment on which it resides; (d) contain no
encrypted imbedded key unknown to NYNEX, node lock, time-out or other function,
whether implemented by electronic, mechanical or other means, which restricts or
may restrict use or access to any programs or data developed under this
Agreement, based on residency on a specific hardware configuration, frequency of
duration of use, or other limiting criteria ("Illicit Code") except, and to the
extent, required by NYNEX as set forth in "Revised Section 14 Document". Should
any program have any of the foregoing attributes, and notwithstanding anything
elsewhere in this Agreement to the contrary, SUPPLIER shall be in default of
this Agreement, and no cure period shall apply. In addition to any other
remedies available to it under this Agreement, NYNEX reserves the right to
pursue any civil and/or criminal penalties available to it against the SUPPLIER.

covered or exempt under Part 68. SUPPLIER agrees to defend and hold NYNEX and
its AFFILIATES harmless from any liability, claim or demand (including the
costs, expenses and reasonable attorney's fees on account thereof) that may
arise out of SUPPLIER's non-compliance with Part 68. NYNEX agrees to promptly
notify SUPPLIER of any liability, claim or demand against NYNEX or its
AFFILIATES for which SUPPLIER is responsible under this clause and gives
SUPPLIER full opportunity and authority to assume the defense, including
appeals, and to settle such liability, claims and demands,

      When SUPPLIER has given NYNEX such discontinuance notice, or if for any
other reason SUPPLIER is unable to provide such MATERIAL, or SOFTWARE, SUPPLIER
shall, if requested by NYNEX, endeavor to arrange for a third party to continue
to furnish the discontinued maintenance, replacement and repair parts to NYNEX.
In the event SUPPLIER is not requested or, if requested, is unable to find a
third party to furnish such parts to NYNEX, SUPPLIER shall, upon request by
NYNEX, to the extent SUPPLIER has such rights, provide NYNEX with existing
technical information and rights, including SOURCE CODE and documentation, at no
additional charge, sufficient for NYNEX to manufacture, or have manufactured,
the discontinued parts. In no event shall the provision of such rights and
technical information to a third party or to NYNEX be delayed beyond six (6)
months after SUPPLIER's date of notice of discontinuance.

      SUPPLIER shall protect against the loss or damage of the existing
technical information required for the manufacture of the discontinued parts
with the same degree of care that SUPPLIER uses to protect its own valuable
technical information. In addition, SUPPLIER shall advise NYNEX in writing at
least six (6) months in advance of its decision to discontinue maintenance of
any technical information, so that NYNEX may acquire such technical information
in accordance with the provisions of this clause.

      The technical information includes, by example and not by way of
limitation: (a) manufacturing drawings and specifications of raw materials and
components comprising such parts; (b) manufacturing drawings and specifications
covering special tooling and the operation thereof; and (c) a detailed list of
all commercially available parts and components purchased by the SUPPLIER on the
open market disclosing the part number, name, and location of the SUPPLIER and
price lists for the purchase thereof, including SOURCE CODE and documentation.

      In addition to the provisions for repair or replacement or MATERIAL and/or
SOFTWARE set forth in Article 13 hereof, entitled "WARRANTIES" and Section 12.9
hereof, entitled "REPAIRS AND REPLACEMENT," SUPPLIER agrees, in any event, if
any natural or other disaster or emergency causes an out of service condition,
SUPPLIER shall use extraordinary effort to locate or provide (i.e. procure or
manufacture) and ship to NYNEX replacement MATERIAL or SOFTWARE, and make
available necessary manpower within twenty four (24) hours of verbal
notification by NYNEX or its AFFILIATES.

      Such emergency support shall be available twenty four (24) hours a day,
seven (7) days a week during the term of this Agreement and for a period of
twenty (20) years after the expiration of this Agreement.

      Charges for replacement MATERIAL, SOFTWARE, AND SERVICES shall be at the
prices contained in Appendix C hereof, entitled PRICING, or Appendix D hereof,
entitled CHANGES IN SCOPE, as applicable, for the term of this Agreement. This
clause shall not be construed to required SUPPLIER to maintain any inventories

                                   WORKAROUND

      In the event SUPPLIER fails to furnish any SYSTEM, PRODUCT, MATERIAL,
SOFTWARE or SERVICES, or any combination thereof, that conform to approved
SPECIFICATIONS by the agreed upon original delivery date, or an amended delivery
or completion date, for reasons other than FORCE MAJEURE, or delays caused
solely, directly and independently of all other causes by NYNEX or its
AFFILIATES' failure to meet their obligations to SUPPLIER, and NYNEX determines
that SUPPLIER's failure to meet its obligations will cause NYNEX or its
AFFILIATES to incur additional costs to meet commitments to their customers,
then NYNEX may notify SUPPLIER in writing, in accordance with Section 30.10
hereof, that a WORKAROUND condition exists. SUPPLIER shall then be granted a
cure period as set forth in Section 10.8 hereof, entitled Performance
Compensation Cure Period. In the event that the failure is not remedied to
NYNEX's reasonable satisfaction prior to the expiration of the cure period,
NYNEX may invoke SUPPLIER's liability under Section 10.7 hereof, entitled
PERFORMANCE COMPENSATION PAYMENTS.

      In addition, SUPPLIER and NYNEX shall promptly participate in the joint
preparation of a WORKAROUND plan to resolve the problem. NYNEX, however, shall
have final approval of the WORKAROUND plan to be performed.

and further Supplier agrees and acknowledges:

      (i)   that it recognizes that the System(s), Products, Material, Software
            or Services which are to be provided under this Agreement are vital
            to NYNEX and must be delivered and installed without interruption,

            fulfill, the NYNEX or its Affiliate's Order(s) before it satisfies
            such third party Order(s).

      (ii)  that Supplier has and will maintain an organization staffed by

including without limitation those set forth in Section 26.1(D).

      NYNEX shall be entitled to damages pursuant to this Article whether or not
NYNEX terminates the Agreement or cancels the applicable Order(s). The receipt
of damages under this Article shall not preclude NYNEX or its AFFILIATE from any
other rights and remedies to which they are entitled under the terms and

                             PERFORMANCE STANDARDS

     20.1     Performance Standards are set forth in Article 12 hereof, entitled
Quality Assurance, together with those as shall be set forth in the applicable
Order(s). Supplier shall meet or exceed such performance standards in all work
performed or Material or Software provided under this Agreement or any Order(s).
The utilization of such minimum performance standards and the identification of
those damage elements which will be reimbursed as compensation for failure to
satisfy the requirements of the minimum performance standards is not intended
and should not be construed as sanctioning performance at or below such
standards. The sole purpose of such compensation is to provide a mechanism
within the context of the ongoing performance of the Agreement under which NYNEX
would determine and receive compensation, should SUPPLIER fail in its
performance, without immediate resort to Article 21 hereof, entitled DEFAULT.
Accordingly, under normal circumstances resort to and utilization of the
Performance Compensation Payments shall preclude the subsequent exercise of the
Default provision for those specific performance events for which compensatory
damages have been assessed and reimbursed. However, said specific performance
events shall be counted in determining the cumulative failure of Supplier to
meet the material performance requirements of this Agreement or any Order(s).
Failure to meet material performance requirements shall occur, if Supplier
performs below the minimum performance requirements consistently over a   [ * ]
coincides with a calendar year. NYNEX shall have the option to invoke Default,
should Supplier fail to meet the material performance requirements of this
Agreement or any Order(s) issued pursuant to this Agreement.

      21.1 Supplier shall be in default as defined in this Article, if Supplier
fails to:

      (i)   individually, or in the aggregate over time, in any material
            respect, make delivery of any Material or Software or to perform any

            hereof, entitled PERFORMANCE STANDARDS, or Article 17 hereof,
            entitled WORKAROUND.

      (iii) perform any of its other material obligations under this Agreement;
            or

      (iv)  make progress so as to endanger performance of this Agreement or any
            Order(s) in accordance with its terms; and, in any of the
            circumstances specified in this Article, Supplier cannot demonstrate
            that the Material, Software or other deliverable(s) or service(s)
            will conform to this Agreement or any Order(s) and satisfy the
            Acceptance Criteria, or that the SUPPLIER's employees as a group

            Software which will conform to this Agreement or any Order(s) and
            satisfy the Acceptance Criteria; NYNEX may give Supplier written
            notice citing the areas believed to be inadequate or deficient.

      21.2 In the event of any Supplier Default under Section 21.1 or other
failure to perform any duty or obligation under this Agreement or any Order(s)
issued pursuant to this Agreement ("Default"), NYNEX shall provide Supplier with
written Notice thereof, in accordance with Section 30.10 hereof, and Supplier
shall have        [ * ]        from the mailing, or other issuance, of said
notice by NYNEX to cure the Default ("Cure Period"). Should an occasion(s) of
Default arise which the parties agree is of such a nature that it cannot be
remedied within the Cure Period through the application of Supplier's best
efforts, Supplier shall present within such Cure Period a plan of action to
remedy same, which plan shall have, in NYNEX's judgment, a reasonable
opportunity for success. If, at the end of the       [ * ]       period the
Default has not been remedied to the reasonable satisfaction of NYNEX, or a plan
to remedy reasonably acceptable to NYNEX is not presented, as the case may be,
then NYNEX may cause Supplier to be in Default

agreement on the amount of refund and other damages to be received by NYNEX
within the steps and time periods set forth in Article 31, NYNEX shall have the
right to pursue such remedies as may be available at law or in equity or under
this Agreement. Failure of NYNEX to enforce any right under this Article
shall not be deemed a waiver of any right hereunder. The rights and remedies of
NYNEX under this Article shall not be exclusive and are in addition to any other

affiliates or successors in interest and DSC Communications Corporation or DSC

or proceeding against any Indemnitees arising in connection with a Claim, and
shall pay any damages, costs or expenses awarded therein or payable in
settlement; provided, however, that no such settlement shall compromise, impede
or limit in any manner NYNEX's possession, use or distribution of the System,
Product, Material, Software or other item subject to the Claim. NYNEX shall
notify the SUPPLIER promptly, in accordance with Section 30.10 hereof, of any
claim of infringement for which SUPPLIER is responsible, and shall cooperate
with SUPPLIER in every reasonable way to facilitate the defense of any such
claim.

      Without limitation of the foregoing, should NYNEX's or its AFFILIATES' use
of, or full benefit from, the SYSTEM, PRODUCT, MATERIAL, SOFTWARE, DOCUMENTATION

injunction or other court order arising out of any such infringement or other
cause of action for which SUPPLIER is responsible, SUPPLIER shall, in addition
to the above indemnity, at no expense, loss or damage to NYNEX or its AFFILIATES
and, at SUPPLIER's option:

      A.    replace such PRODUCT, SYSTEM, MATERIAL, DOCUMENTATION, LICENSED
            MATERIALS and/or SERVICES which SUPPLIER can demonstrate to NYNEX's
            reasonable satisfaction are equally suitable MATERIAL, DOCUMENTATION

            infringement; or

      B.    modify such MATERIAL, DOCUMENTATION, LICENSED MATERIALS and/or
            SERVICES without reduction or loss of functionality so that it or
            they will be free of infringement; or

      C.    by license or other release from claim of infringement, procure for
            NYNEX' or its AFFILIATES' benefit the right to use, install, sell,
            or resell such MATERIAL, DOCUMENTATION, LICENSED MATERIALS and/or
            SERVICES; or

      D.    i) if none of the foregoing can be rapidly and effectively
            accomplished such that the NYNEX implementation schedules will be
            delayed by more than one hundred and twenty (120) days or such
            longer period as may be agreed to by the Parties; or ii) should an
            effect of the DSC litigation be to materially limit SUPPLIER's
            ability to sell the SYSTEM, PRODUCTS, MATERIAL or SOFTWARE, such
            that SUPPLIER fails to complete the sale of such Material or
            Products, on a generally available basis and in quantities
            comparable to the NYNEX sale, to at least two additional purchasers
            within twenty four (24) months of the date of the completion of
            Phase I of FOA by NYNEX; or iii) should SUPPLIER fail to use its
            best efforts to develop, support or market the Material or Products
            in a commercially reasonable manner; or iv) if SUPPLIER discontinues
            the development or manufacture, or otherwise exits the business of
            providing the SYSTEM, PRODUCT, MATERIAL, or SOFTWARE, or acts in
            such a way as to support a determination by NYNEX that SUPPLIER
            plans to so discontinue manufacture or exit the business, (provided,
            however, that the terms "discontinue" and "exit," as used in this

            discontinues ordering MATERIAL in accordance with its commitments
            under the Agreement, other than replacement parts for MATERIAL
            already installed; SUPPLIER shall, if directed by NYNEX, (1) remove
            the MATERIAL from the premises of NYNEX or its AFFILIATES, or such
            other location, and refund to NYNEX or its AFFILIATES the full
            SYSTEM, PRODUCT, MATERIAL purchase price and any non-recurring
            reasonable amount paid for the use of any associated SOFTWARE and
            the reasonable costs associated with removal thereof, and shall, at
            its own expense, restore the premises as nearly to their original
            condition as is reasonably possible, unless otherwise directed in
            writing by NYNEX or its AFFILIATE; (2)     [ * ]     an amount equal

            NYNEX may terminate the Agreement without liability of any type or
            character to SUPPLER.

      If either NYNEX or SUPPLIER is directed by a court of competent
jurisdiction, after all permissible appeals have been taken, to cease further
use or deployment of, or remove the MATERIAL from the premises of NYNEX or its
AFFILIATES, or such other location, then SUPPLIER shall (1) remove the MATERIAL
from the premises of NYNEX or its AFFILIATES, or such other location, and refund
to NYNEX or its AFFILIATES the full SYSTEM, PRODUCT, MATERIAL purchase price
paid to date and any nonrecurring reasonable amount paid for the use of any

NYNEX or its AFFILIATE; (2) pay to NYNEX an amount equal to all reasonable
charges, costs and expenses (i) to reprocure similar commercially available

assessments or penalties imposed by regulatory agencies as a consequence of such
removal of MATERIAL, whether any of the foregoing damages in items (i) through

            passed is completed and achieved in accordance with the requirements
            of this Agreement; and ii) all DSC Litigation has been concluded and
            SUPPLIER has satisfied any and all obligations arising out of such

                  completion of the infrastructure implementation to the
                  commitment level of eight hundred thousand (800,000)
                  households passed in accordance with the requirements of this

                  Performance Compensation Payments have been assessed by NYNEX
                  against SUPPLIER; or

            2)    by the amount of One Million Dollars ($1,000,000.00) for each
                  one percent (1%) that NYNEX fails to meet the commitment level
                  of households passed by the conclusion of the scheduled
                  infrastructure implementation period, provided such failure is
                  caused solely, directly and independently of all other causes
                  by NYNEX; or

          elsewhere; or

     (c)  resume performance under such order once the delaying cause ceases
          with an option in the injured party to extend the delivery or

     30.12   DISASTER RECOVERY  If any SYSTEM or Component acquired hereunder is
rendered inoperative as a result of a natural or other disaster or emergency
(including major PRODUCT failure or breakdown and peak load conditions),
SUPPLIER will make all reasonable efforts to supply or help locate back-up or
replacement SYSTEMS, Components, and facilities for NYNEX's use, In such event,

permitted by law, and to make the replacement SYSTEM or Component available from
the manufacturing facility currently producing such equipment or from inventory.
Subject to this Agreement, the price for any replacement PRODUCT provided by
SUPPLIER will be in compliance with this Agreement, plus shipment costs;
provided, however, that if the non-operation is due to the negligence or fault
of SUPPLIER, replacement equipment will be provided and delivered at no cost to
NYNEX. NYNEX shall retain the right to accept or reject any offer by SUPPLIER to
supply any emergency or back-up PRODUCT or other equipment or service.

     30.13   RELEASES VOID  Neither party shall require waivers or releases of

                          ALTERNATE DISPUTE RESOLUTION

     31.1   REFERRAL  Should any disagreement, dispute, disputed claim of
breach, nonperformance, or repudiation arising from, related to or connected
with this AGREEMENT or any of the terms or conditions hereof, or any
transactions hereunder ("Dispute"), arise between NYNEX and SUPPLIER either
during this AGREEMENT or after termination or expiration of this AGREEMENT,

will not be prohibited from seeking injunctive relief to preserve the status quo
while the mediation is pending.

     31.2   MEDIATION  A formal mediation procedure may be commenced by either
party under the then current Public Resources ("CPR") Model Procedure for
Mediation of Business Disputes by notice to CPR to select an experienced neutral
mediator and a proposed time and date for mediation. All mediators shall be
selected from the CPR Panel of Neutrals unless the parties mutually agree to a
difference neutral mediator. All mediator fees shall be equally shared by the
parties. Each party will pay its own costs and other expenses associated with
the mediation, except that the reasonable travel expenses, as outlined in the
NYNEX Travel Guidelines, incurred by the party, which is more distant from the
site of the mediation, shall be shared equally by SUPPLIER and NYNEX. The
parties shall participate in good faith in the mediation and if the parties
reach a resolution of the Dispute, it shall be reduced to writing and shall be
enforceable in accordance with its terms.

writing to the other party that the mediation procedure is terminated. Upon the
issuance of such notice, either party shall have the right to pursue such
remedies as may be available at law or in equity or under this Agreement.

     ALL DISCUSSIONS AND DOCUMENTS PREPARED PURSUANT TO ANY ATTEMPT TO RESOLVE A
DISPUTE UNDER THIS PROVISION ARE CONFIDENTIAL AND FOR SETTLEMENT PURPOSES ONLY
AND SHALL NOT BE ADMITTED IN ANY COURT OR OTHER FORUM AS AN ADMISSION OR
OTHERWISE AGAINST A PARTY FOR ANY PURPOSE INCLUDING THE APPLICABILITY OF FEDERAL
AND STATE COURT RULES.]

     31.3   INDEPENDENT OBLIGATION OF SUPPLIER TO CONTINUE PERFORMANCE  Because
of the critical importance of the obligations undertaken by SUPPLIER hereunder
to the operations of NYNEX and the substantial expertise and manufacturing
capability and capacity (not otherwise possessed by NYNEX) which SUPPLIER has
represented it will utilize in connection with the fulfillment of its
obligations and the reliance of NYNEX on such expertise, capability and
capacity, SUPPLIER assumes an independent obligation to continue performance of
its obligations hereunder in all respects regardless of any dispute which may
arise between NYNEX and SUPPLIER in connection with any claims by SUPPLIER that
NYNEX has materially breached its obligations hereunder. Such independent
obligation shall continue for ninety (90) days from the date upon which NYNEX
receives written notice of such alleged breach from SUPPLIER. SUPPLIER
undertakes this independent obligation without prejudice to any rights or
remedies it may otherwise have in connection with any dispute between SUPPLIER
and NYNEX.

                                   ARTICLE 32

This Amendment No. 1 to Contract X-134094D dated October 6, 1996 ("Amendment")
is entered into between Telesector Resources Group, Inc. d/b/a Bell Atlantic
Network Services, a Delaware Corporation, having an office located at 240 East
38th Street, New York, New York 10016 (hereinafter "Bell Atlantic") on behalf of
itself and for the benefit of its Affiliates, and General Instrument Corporation
of Delaware, representing its financial interests in Next Level Communications
in Contract X-134094D, and Next Level Communications, a Delaware Limited
Partnership, having an office at 6085 State Farm Drive, Rohnert Park, CA 94928,
(hereinafter collectively referred to as "Supplier").

NOW THEREFORE, the parties agree as follows:

1 . SCOPE OF AMENDMENT

Under this Amendment, Bell Atlantic and Supplier agree to modify the dollar
amount of the Performance Bond or Irrevocable Letter of Credit and set SSU-2
hardware and functionality pricing.

2. PERFORMANCE BOND OR IRREVOCABLE LETTER OF CREDIT

Section 26.2 of the Agreement, entitled "Performance Bond or Irrevocable Letter
of Credit," is hereby deleted in its entirety and replaced with the following:

SUPPLIER shall obtain and maintain, during the terms of this Agreement or any
Order(s) issued pursuant to the Agreement and any extensions thereof, a
performance bond ("Bond") or Irrevocable Letter of Credit ("LC") in the penal
sum of Twenty Five Million Dollars ($25,000,000.00). SUPPLIER shall maintain the
Bond(s) or LC(s) according to the following schedule:

A)       Upon completion of the infrastructure implementation to the level of
         one hundred thousand (100,000) households passed, SUPPLIER shall
         increase the Bond or LC to an amount of Fifty Million Dollars
         ($50,000,000).

A)       Upon completion of the infrastructure implementation to the level of
         one hundred and fifty thousand (150,000) households passed, SUPPLIER
         shall increase the Bond or LC to an amount of Seventy Five Million
         Dollars ($75,000,000).

The Bond or LC may be canceled in its entirety if, and only if the following
conditions have been satisfied: i) no default has occurred and no Performance
Compensation Payments have been assessed by Bell Atlantic against SUPPLIER; and
ii) Supplier provides proof satisfactory to Bell Atlantic, in the form of
financial statements, D&B ratings, and such other means identified by Bell
Atlantic in the Financial Accountability Requirement, that SUPPLIER's financial
ability and assets adequately back and provide sufficient security against any
further contingencies arising out of Article 19 hereof entitled REPORT RATE,
Article 21 hereof, entitled DEFAULT and Article 26 hereof, entitled INTELLECTUAL
PROPERTY - GENERAL OBLIGATIONS.

Under said Bond or LC, the Principal and the Surety(ies) shall be firmly bound
to Bell Atlantic in the foregoing penal sum and shall promptly pay Bell Atlantic
in accordance with and pursuant to Article 19 hereof, entitled REPORT RATE, or
Article 21 hereof, entitled DEFAULT or Article 26, entitled INTELLECTUAL
PROPERTY - GENERAL OBLIGATIONS or Article 31

                                                                 Amendment No. 1
                                                                     Page 2 of 3

hereof, entitled ALTERNATE DISPUTE RESOLUTION, if it is determined, by the
Mediator under Article 31 or by the Supreme Court of the State of New York or
any United States District Court, that SUPPLIER has failed to perform or fulfill
any of the undertakings covenants, terms, conditions or requirements of this
Agreement or any extension or modification thereof; provided however, that any
penal sums assessed in accordance with the terms of the Agreement shall be, in
the first instance, the responsibility of General Instrument, acting as
Principle, and it shall be at General Instrument's initial discretion as to
whether such penal sums are paid to Bell Atlantic through its own assets or from
the Bond or LC; provided however that if such penal sums are not paid by General
Instrument within 90 days of their assessment, Bell Atlantic shall have the
right to directly claim against the Bond or LC and invoke its right to prompt
payment under the Bond or LC.

In the event that liabilities occur and damage sums are assessed, those sums
shall be limited only to the actual amounts arising out of the claim, and shall
not be construed as a forfeiture of the entire amount of the Bond or LC.
Furthermore, prior to any claim by Bell Atlantic against the Bond, the claim
must have been submitted to General Instrument and all due process including
those contained in Article 31 of the Agreement shall have been acted upon.

The Surety(ies) for said Bond shall be a major insurance corporation or other
major financial institution licensed to do business in the State of New York and
with a Bests Rating of A10 or better, whose principal assets are located in the
United States of America or shall appear on the Departments of Treasury's list
of approved sureties and must act within the limitations listed therein. The
commercial bank providing the Irrevocable Letter of Credit shall be chartered or
licensed by either the United States, or by New York State, shall be rated A- or
better by Standard & Poor's, and shall have capital in excess of one billion
dollars ($1,000,000,000.).

3. SSU HARDWARE AND FUNCTIONALITY

To ensure an economic, efficient and timely method of providing special
services, Next Level Communications has agreed to provide to Bell Atlantic SSU-2
hardware and functionality at a price equal to that of the current FXTIU.

4. OTHER TERMS UNCHANGED

All other terms and conditions of the Agreement shall remain unchanged.

5. ENTIRE AMENDMENT

This Amendment constitutes and embodies the entire agreement by and between the
parties hereto and supersede all prior oral or written agreements or
understandings, if any, between them with respect to the subject matter of this
Amendment.

This document supplements previously exchanged documentation; in the event of
conflict between the Terms of this document and previously exchanged
documentation, this document shall control and take precedence.

1.      ATM & SONET

        SUPPLIER specifically represents and warrants that all SYSTEMS,
PRODUCTS, MATERIAL, and SOFTWARE and to be supplied hereunder shall be fully
compatible with all ATM and SONET related SYSTEMS, PRODUCTS, MATERIAL, and
SOFTWARE and obtained by NYNEX and/or its AFFILIATES, irrespective of the
manufacturer of such aforementioned ATM and SONET related items. SUPPLIER shall
have the opportunity to review and comment upon NYNEX's and/or its AFFILIATES'
Sonet and ATM technical requirement specifications contained in current and
future NYNEX RFPs. SUPPLIER shall within ninety (90) days of notification by
NYNEX and/or its AFFILIATES of the manufacturer selected by NYNEX, verify, test
and perform such work as shall be necessary to ensure and guarantee that all
SYSTEMS, PRODUCTS, MATERIAL, and SOFTWARE furnished under this Agreement shall
be compatible with any and all ATM and SONET related SYSTEMS, PRODUCTS,
MATERIAL, and SOFTWARE of the manufacturer identified by NYNEX and/or its
AFFILIATES, SUPPLIER shall be responsible for any necessary changes to SYSTEMS,
PRODUCTS, MATERIAL, and SOFTWARE that are ATM or SONET related or supplied
hereunder due to inoperability resulting from a lack of compatibility. NYNEX
and/or its AFFILIATES shall use its best effort to assist SUPPLIER in its
efforts to secure the necessary cooperation from NYNEX's and/or its AFFILIATES'
ATM and SONET related suppliers, provided, however, it is understood and agreed
that NYNEX and/or its AFFILIATES shall act only as a mediator and to establish
priorities in reference to issues of inoperability between such SONET suppliers,
ATM suppliers and SUPPLIER hereunder. All SUPPLIER activity under this Article
shall be included in the [ * ] to NYNEX and/or its AFFILIATES.

2.      SPECIAL SERVICES

        SUPPLIER shall provide to NYNEX an economical, efficient and timely
method of providing special services as outlined in section 4 of the RFP and
Section 3 of the RRP. SUPPLIER'S special service solution shall not result in
any degradation to NYNEX's and/or its AFFILIATES' customers' existing service(s)
nor necessitate re-wiring of the such customers' internal premises. NYNEX and
SUPPLIER shall mutually agree upon a schedule which identifies the
service/functionality and the service delivery architecture which shall be
jointly developed by NYNEX and SUPPLIER. The costs for providing a special
service over the SUPPLIER's architecture shall not necessitate an increase in
the tariff pice for the service (as compared to current DLC/ODLC serving
architectures). NYNEX shall, if requested by SUPPLIER, assist SUPPLIER in the
identification of and the prioritizing of all special services as necessary.
NYNEX shall continue to hold formal meetings to address the

        15.3.   Plan to Address Bandwidth Limitations of BDT

        SUPPLIER and NYNEX acknowledge that the current design of SUPPLIER
system specifies two OC-12c interfaces at the HDT for Broadcast Services and one
OC-12c interface for Interactive Services as well as that NYNEX marketing
requirements (as indicated in the RFP and RRP) exceed these capacities. SUPPLIER
shall pursue and propose to NYNEX viable cost effective capacity upgrade
strategies that shall, at a minimum, provide one additional OC-12c interface for
NYNEX Broadband Services. This upgrade on the part of SUPPLIER shall be
accomplished without excessive down time for existing system retrofits
(backwards compatibility). The cost to NYNEX for this additional capacity shall

any Business Day prior to the Expiration Date by delivering the Warrant
Certificate, with a duly executed Exercise Form with the conversion section

particular date (the "Determination Date") shall mean the average of the "daily
sales prices" of the Common Stock on the Nasdaq National Market on the last 20
Business Days prior to the Determination Date. The "daily sales price" shall be

stock dividend payable in shares of Common Stock or (ii) the number of shares of
Common Stock shall have been

                                                                               5



increased by a subdivision or split-up of shares of Common Stock, then, on the
date of the payment of such dividend or immediately after the effective date of
subdivision or split up, as the case may be, the number of shares to be
delivered upon exercise of this Warrant will be increased so that the
Warrantholder will be entitled to receive the number of shares of Common Stock
that such Warrantholder would have owned immediately following such action had
this Warrant been exercised immediately prior thereto, and the Exercise Price
will be adjusted as provided below in paragraph (g).


            (b) Combination of Stock. If the number of shares of Common Stock
outstanding shall have been decreased by a combination of the outstanding shares
of Common Stock (including a reverse stock-split), then, immediately after the
effective date of such combination, the number of shares of Common Stock to be
delivered upon exercise of this Warrant will be decreased so that the
Warrantholder thereafter will be entitled to receive the number of shares of
Common Stock that such Warrantholder would have owned immediately following such
action had this Warrant been exercised immediately prior thereto, and the
Exercise Price will be adjusted as provided below in paragraph (g).



            (c) Reorganization, etc. If any capital reorganization of the
Company, or any reclassification of the Common Stock, or any consolidation of
the Company with or merger of the Company with or into any other person, shall
be effected in such a way that the holders of Common Stock shall be entitled to
receive stock, other securities or assets (whether such stock, other securities
or assets are issued or distributed by the Company or another person) with
respect to or in exchange for Common Stock, then, upon exercise of this Warrant
the Warrantholder shall have the right to receive the kind and amount of stock,
other securities or assets receivable upon such reorganization,
reclassification, consolidation or merger by a holder of the number of shares of
Common Stock that such Warrantholder would have been entitled to receive upon
exercise of this Warrant had this Warrant been exercised immediately before such
reorganization, reclassification, consolidation or merger.


            (d)  Stock and Rights Offering at Less than Fair Market Value.

                  (i) If at any time the Company shall issue to all holders of
      its Common Stock or sell or fix a record date for the issuance to all
      holders of its Common Stock of Common Stock at a price per share that is
      less than Fair Market Value per share of Common Stock (as defined in
      Section 1.2(c) hereof) on the date of such issuance or such record date
      then, immediately after the date of such issuance or sale or on such
      record date, the number of

                                                                               6



      shares of Common Stock to be delivered upon exercise of this Warrant shall
      be increased so that the Warrantholder thereafter will be entitled to
      receive the number of shares of Common Stock determined by multiplying the
      number of shares of Common Stock such Warrantholder would have been
      entitled to receive immediately before the date of such issuance or sale
      or such record date by a fraction, the denominator of which will be the
      number of shares of Common Stock outstanding on such date plus the number
      of shares of Common Stock that the aggregate offering price of the total
      number of shares so offered for subscription or purchase would purchase at
      such Fair Market Value, and the numerator of which will be the number of
      shares of Common Stock outstanding on such date plus the number of
      additional shares of Common Stock offered for subscription or purchase,
      and the Exercise Price shall be adjusted as provided below in paragraph
      (g).

                  (ii) If the Company shall at any time distribute to all
      holders of its Common Stock any shares of capital stock of the Company
      (other than Common Stock) or evidences of its indebtedness or assets
      (excluding cash dividends or distributions paid from retained earnings of
      the Company) or rights or warrants to subscribe for or purchase any of its
      securities (any of the foregoing being hereinafter in this paragraph
      (d)(ii) called the "Securities"), other than pursuant to a reorganization,
      reclassification, consolidation or merger described in paragraph (c), then
      in each such case, unless the Company elects to reserve shares or other
      units of such Securities for distribution to the Warrantholder upon
      exercise of the Warrants of such Warrantholder so that, in addition to the
      shares of the Common Stock to which such Warrantholder is entitled, such
      Warrantholder will receive upon such exercise the amount and kind of such
      Securities that such Warrantholder would have received if the
      Warrantholder had, immediately prior to the record date for the
      distribution of the Securities, exercised the Warrant, then the number of
      shares of Common Stock to be delivered to such Warrantholder upon exercise
      of this Warrant shall be increased so that the Warrantholder thereafter
      shall be entitled to receive the number of shares of Common Stock
      determined by multiplying the number of shares such Warrantholder would
      have been entitled to receive immediately before such record date, had the
      Warrantholder exercised the Warrant immediately prior thereto by a
      fraction, the denominator of which shall be the Fair Market Value per
      share of Common Stock on such record date minus the then fair market value
      (as reasonably determined by the Board of Directors of the Company), of
      the portion of the capital stock or assets or evidences of indebtedness so
      distributed or of such rights or warrants applicable to one share of
      Common Stock and the numerator of which shall be the Fair Market Value per
      share of the Common

      Stock, and the Exercise Price shall be adjusted as provided below in
      paragraph (g).

                  (iii) For the purpose of making any adjustment required under
      this Section 6.1(d), the consideration received by the Company for any
      issue or sale of securities shall (a) to the extent it consists of cash be
      computed as the gross amount of cash received by the Company before
      deduction of any expenses payable by the Company and any underwriting or
      similar commissions, discounts, compensation or concessions paid or
      allowed by the Company in connection with such issue or sale, (b) to the
      extent it consists of property other than cash, be computed at the fair
      value of that property as reasonably determined in good faith by the Board
      of Directors and (c) if additional shares of Common Stock, securities
      convertible into Common Stock or rights or options to purchase either
      additional shares of Common Stock or such convertible securities or are
      issued or sold together with other stock or securities or other assets of
      the Company for a consideration which covers both, be computed as the
      portion of the consideration so received that may be reasonably determined
      in good faith by the Board of Directors to be allocable to such additional
      shares of Common Stock, such convertible securities or rights or options.

            (e) Fractional Shares. No fractional shares of Common Stock or scrip
shall be issued to any Warrantholder in connection with the exercise of this
Warrant. Instead of any fractional shares of Common Stock that would otherwise
be issuable to such Warrantholder, the Company will pay to such Warrantholder a
cash adjustment in respect of such fractional interest in an amount equal to
that fractional interest of the Fair Market Value per share of Common Stock as
of the close of business on the Business Day immediately preceding the exercise
of the Warrant.

            (f) Carryover. Notwithstanding any other provision of this Section
6.1, no adjustment shall be made to the number of shares of Common Stock to be
delivered to the Warrantholder (or to the Exercise Price) if such adjustment
represents less than 1% of the number of shares to be so delivered, but any
lesser adjustment shall be carried forward and shall be made at the time and
together with the next subsequent adjustment that together with any adjustments
so carried forward shall amount to 1% or more of the number of shares to be so
delivered.

            (g) Exercise Price Adjustment. Whenever the number of Warrant Shares
purchasable upon the exercise of the Warrant is adjusted as provided pursuant to
this Section 6.1, the Exercise Price payable upon the exercise of this Warrant
shall be adjusted by multiplying such Exercise Price immediately prior to such
adjustment by a fraction, of which the numerator shall be the number of Warrant
Shares purchasable upon the exercise of the Warrant immediately prior to such
adjustment, and of which the

                                                                               8


denominator shall be the number of Warrant Shares purchasable immediately
thereafter; provided, however, that the Exercise Price for each Warrant Share
shall in no event be less than the par value of such Warrant Share.

            6.2 Notice of Adjustment. Whenever the number of Warrant Shares or
the Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail by first class, postage prepaid, to the
Warrantholder, a notice of such adjustment or adjustments setting forth the
number of Warrant Shares and the Exercise Price such adjustment, a brief
statement of the facts requiring such adjustment and the computation by which
such adjustment was made.

            7.  Miscellaneous.

            7.1 Binding Effect; Benefits. This Warrant shall inure to the
