                               PROSPECTUS SUMMARY

     This summary highlights selected information contained elsewhere in this
prospectus. This summary is not complete and does not contain all of the
information that you should consider before buying shares in this offering. We
urge you to read the entire prospectus carefully. Unless stated otherwise, the
information contained in this prospectus assumes that the Underwriters'
over-allotment option to purchase 900,000 shares from the selling stockholders
is not exercised and assumes a one-for-two reverse split of our common stock to
be effected prior to the closing of this offering.

                                  OUR BUSINESS


     Paradyne Networks, through its wholly-owned subsidiary, Paradyne
Corporation, is a leading developer, manufacturer and distributor of broadband,
or high-speed digital, and narrowband, or conventional analog, communications
products for network service providers and business customers. We offer
cost-effective hardware and software products that enable business class,
service level managed, high-speed connectivity over the existing telephone
network infrastructure. We believe that demand for high-speed, broadband
transmission will continue to increase as more business and residential users
find narrowband access technologies inadequate to meet their high-speed
requirements. Our objective is to maintain and build upon our position as one of
the leaders in the broadband access market by focusing on next generation
digital subscriber line, more commonly known as DSL, service level management,
more commonly known as SLM, and other broadband access products. We have a long
history of technological innovation, and we hold over 155 U.S. patents and have
over 100 U.S. patent applications pending. We have sold our products to over 50%
of the Fortune 500 companies and to businesses and network service providers in
over 125 countries.


     Since 1996, various DSL products and technologies have been introduced into
the market to increase the speed and reduce the complexity of deploying high
speed data and voice services over the traditional copper telephone
infrastructure. DSL products are installed on each end of a telephone line and
simultaneously permit high-speed data transmission and voice services. The
advantages of DSL include the ability to be deployed on the existing copper
infrastructure worldwide, to operate at higher speeds for less cost, and to
allow network service providers to offer services that are "always-on" and don't
require the user to initiate a new connection each time the service is used.

     Since 1996, various SLM products and technologies have been developed to
allow network managers to obtain critical information regarding the performance
of their networks. Frame Relay is a technology that puts data into packets, or
envelopes, and transports the data across a network that is shared by many
customers. In many cases, SLM technology allows network managers who purchase
shared data services, such as Frame Relay, to obtain information about their
portion of the shared service. Before SLM, this information was unavailable and
network managers were not able to confidently evaluate the performance of
critical applications over shared services.

     Over the past several years, data traffic generated by computer users
accessing the Internet or business networks has increased significantly and is
expected to continue in the future. As a result of changes in the
telecommunications industry and the increased demand for high-speed
transmission, network service providers are requiring flexible solutions that
meet their current needs and permit easy, cost-effective enhancements in the
future.

     Our current hardware and software products include the following:

     - Broadband DSL.  Our Hotwire hardware products deliver broadband DSL
       access across the existing copper wire infrastructure, more commonly
       known as the local loop. Our Hotwire products enable network service
       providers to provide broadband access services to business customers,
       teleworkers and residential customers at substantially reduced rates
       compared to conventional service offerings. The recently introduced
       SuperLine system was jointly developed by Paradyne and AG Communications
       Systems. Superline incorporates Paradyne's Tripleplay technology that
       allows network service providers to offer cost effective, multiple line
       voice and high speed data services over a single traditional telephone
       line to residential customers, small offices and home offices.

                                        1

     - Broadband Service Level Management.  The FrameSaver solution consists of
       a suite of software and hardware products that enable customers to view
       performance statistics and troubleshoot failures across the Frame Relay
       network.

     - Broadband Conventional Access.  Our Acculink and NextEdge products enable
       network service providers and business customers to offer cost-effective,
       service level managed, high-speed access to public and private networks.

     - Narrowband Products.  Introduced in the early 1990s, our Comsphere modems
       enable network service providers and business customers to build
       low-cost, centrally managed networks over dial up or dedicated analog
       circuits.

     The end-users of our equipment are primarily network service providers and
business customers. Network service providers use our broadband products to
enable high speed managed connections between the network service providers'
central office and the customer premise. Moreover, our broadband products enable
network service providers to more efficiently provide network access services by
allowing a high level of management, monitoring and control over network access
equipment and circuits. Business customers use our broadband products for
high-speed connections of voice and data communications to connect their
employees to corporate networks and to the Internet using both public services
and private leased line services provided by network service providers. We sell
our products worldwide through a multi-tier distribution system that includes
direct sales, strategic partner sales, network service provider sales and
traditional distributor or value added reseller sales. Our network service
providers and business customers include AT&T, Ameritech, Bank of America, First
Union, Lucent, NTT, Rhythms, SITA, Sprint and Unisys.

     Paradyne Corporation was originally incorporated in Delaware in 1969,
acquired by AT&T in 1989 and spun out of AT&T as part of Lucent Technologies in
1996. In July 1996, a limited partnership controlled by the Texas Pacific Group
acquired Paradyne Corporation and formed Paradyne Acquisition Corp. as a holding
company to hold the shares of common stock of Paradyne Corporation. In June
1999, Paradyne Acquisition Corp. changed its name to Paradyne Networks, Inc. Our
corporate headquarters are located at 8545 126th Avenue North, Largo, Florida
33773. Our telephone number is (727) 530-2000.

                                  RISK FACTORS

     This offering and an investment in our common stock involve a high degree
of risk. Please carefully consider the following risk factors and the other
information in this prospectus before deciding to purchase shares of our common
stock. Any of the following risks could seriously harm our business and results
of operations. As a result, the trading price of our common stock could decline,
and you could lose part or all of your investment.

RAPID TECHNOLOGICAL CHANGE COULD RENDER OUR PRODUCTS OBSOLETE

     The telecommunications and data communications markets are characterized by
rapid technological change. Our success will depend on our ability to adapt and
to respond to technological changes. If we fail to keep pace with technological
change, our product sales could suffer.

     Our existing products could become obsolete or unmarketable as a result of
the emergence of new industry standards or customer demands. For example, our
customers could determine that they no longer require service level management,
or SLM, with network access products. Furthermore, our products could become
obsolete or unmarketable as a result of any new technology or products which are
superior to ours. We may be unable to compete effectively if we are unable to
adapt to changes in industry standards, meet customer demands or develop new
products or enhancements to existing products.

     Our products compete with numerous high-speed access technologies,
including cable modems, satellite technology and other wireless technologies.
These competing technologies may ultimately prove to be superior to our
products. Our products may become uncompetitive or obsolete as a result of the
development of competing technologies that are more reliable, faster and less
expensive than our technology. For example, substantially all of our products
are deployed in networks that use standard copper telephone wires. The physical
properties of copper wire limit the speed and distance over which data can be
transmitted. Service levels degrade as distance from the central switching
station increases. Other competing technologies, such as wireless and cable are
not subject to such limitations.

OUR SUCCESS WILL DEPEND ON THE ACCEPTANCE OF NEW TELECOMMUNICATIONS SERVICES
BASED ON DSL

     Our future success is substantially dependent upon whether DSL technology
gains widespread market acceptance by network service providers, or NSPs, and
end users of their services. If DSL technology fails to gain widespread
acceptance, our revenues and results of operations may be adversely affected.
Historically, we focused on providing innovative solutions to the narrowband
access market. We, however, are increasingly focusing on the broadband access
market. We have invested substantial resources in the development of DSL
technology, and many of our products are based on DSL technology. Many NSPs
continue to evaluate DSL technology and other alternative high-speed data access
technologies, but they may not continue to pursue the deployment of DSL
technology. Even if NSPs adopt policies favoring full-scale deployment of DSL
technology, they may not choose to purchase our DSL product offerings. In
addition, we have limited ability to influence or control decisions made by
NSPs. NSPs are continuously evaluating alternate high-speed data access
technologies and may, at any time, adopt technologies other than the DSL
technologies offered by us.

WE ARE SUBSTANTIALLY DEPENDENT ON NETWORK SERVICE PROVIDERS, WHO MAY REDUCE OR
DISCONTINUE THEIR PURCHASE OF PRODUCTS OR SERVICES AT ANY TIME

     We estimate that sales to NSPs accounted for approximately 40% of our total
revenues in 1998. If our NSP customers are forced to defer or curtail their
capital spending programs, we could lose, or experience delays or reductions in
significant sales to such customers. Given the capital requirements, complex
regulatory framework and other barriers to entry in the market, there are a
limited number of NSPs. The market for many of the services provided by NSPs has
only begun to emerge since the passage of the Telecommunications Act of 1996 and
many NSPs are still building their infrastructure and rolling out their
services. Many of these NSPs still need to develop, construct and expand their
networks. The inability of our emerging NSP customers to complete development of
their networks, attract or retain customers, respond to trends, such as price
reductions for their services or diminished demand for telecommunications
services generally, could cause them to reduce their capital spending programs.

                                        4
<PAGE>   9

     Generally, our NSP customers do not have an obligation to purchase
additional products or services from us. Termination of purchase arrangements
with these NSP customers or a significant reduction or delay in the amount of
our products they order could materially and adversely affect our revenues. In
addition, the telecommunications industry has recently experienced
consolidation, which may cause us to lose NSP customers. The loss of one or more
of our NSP customers could also materially and adversely affect our revenues.

OUR SUCCESS DEPENDS ON NETWORK SERVICE PROVIDERS INCORPORATING OUR PRODUCTS INTO
THEIR INFRASTRUCTURE

     We anticipate that a significant portion of our future revenues will be
attributable to sales to NSPs of our DSL, SLM and other broadband products. Our
future performance will therefore be substantially dependent on incorporation of
our products by NSPs into their service offerings to subscribers. The failure of
our products to become an accepted part of NSPs' service offerings or a slower
than expected increase in the volume of sales by us of SLM products could
materially and adversely affect our revenues. Our success in the NSP market will
depend on numerous factors, many of which are outside our control. Some of these
factors include:

     - NSP and subscriber acceptance of and satisfaction with our products;

     - the realization of operating cost efficiencies for NSPs when SLM products
       are deployed and our ability to demonstrate these operational benefits;

     - subscriber demand for our products and support for our products within
       the NSPs' sales force;

     - our successful development of systems and products that address the
       requirements for products deployed as part of an NSP's infrastructure;

     - the timing and successful completion of integration development work by
       NSPs to incorporate our SLM functionality into their operational support
       system; and

     - the absence of new technologies that make our products and systems
       obsolete before they can achieve broad acceptance.

VARIOUS FACTORS COULD CAUSE OUR RESULTS TO FLUCTUATE

     Paradyne's quarterly and annual results of operations have fluctuated in
the past and are likely to fluctuate significantly in the future due to a
variety of factors, many of which are outside of our control. Fluctuations in
our results could cause our stock price to decline substantially. Some of these
factors that might affect our results of operations include:

- - The timing and amount of, or cancellation or rescheduling of, orders for our
  products and services to existing and new customers. This may adversely affect
  our operating results in any particular quarter if we were unable to recognize
  revenue for a particular sale in the quarter in which such sale was expected.

- - Our ability to develop, introduce, ship and support new products and product
  enhancements and manage product transitions on a timely basis. Our failure to
  accomplish these tasks could render our products obsolete or non-competitive,
  particularly since technology in our industry changes often. As a result,
  customers may decide to purchase competitive products, which could cause our
  revenues to suffer.

- - Announcements, new product introductions and reductions in price of products
  offered by our competitors. These events could also cause our customers to
  decide to purchase the products of our competitors which would adversely
  affect our revenues and, therefore, our results of operations. Also, we may
  feel it necessary to reduce prices of our products, which could impact
  operating margins and net income.

- - Our ability to achieve cost reductions. As with all companies, we constantly
  strive to improve our margins through reductions in our cost of sales. Failure
  to reduce our costs could reduce our margins which in turn could adversely
  affect our ability to operate profitably.

                                        5
<PAGE>   10

- - Our ability to obtain sufficient supplies of sole or limited source components
  for our products. If we cannot obtain components for our products, we may be
  unable to produce sufficient quantities of our products to meet demand. As a
  result, our revenues could be adversely affected. This is particularly true
  with respect to obtaining sole or limited source components because
  replacements sources, if any, will take time to identify.

- - The timing and rate of deployment of our products by NSPs. The timing and rate
  of deployment by NSPs can affect sales of products to these NSPs and, in turn,
  our operating results.

- - Preferential pricing arrangements. We have preferential pricing arrangements
  with some of our customers. In our effort to win new business we may negotiate
  preferential pricing arrangements in the future with other customers. While
  these arrangements are intended to provide greater revenue, they will have a
  negative impact on our margins. Furthermore, because our strategy relies on
  entering into these arrangements in the future, if we fail to do so, our
  results could be below expectations.

- - Our ability to attain and maintain production volumes and quality levels for
  our products. Many factors could affect our ability to maintain production
  volumes and quality levels. They include an inability to obtain raw materials
  or components, labor shortages, and the maintenance of adequate facilities for
  production. If we fail to maintain production volumes or quality level we may
  be unable to produce sufficient quantities of our products to meet demand,
  which would adversely affect our revenues.

- - The mix of products sold and the mix of distribution channels through which
  they are sold. The mix of products sold can adversely affect our results.
  Margins vary within our newer and older products. If we fail to successfully
  sell our higher margin products, our gross margins may be lower than expected.
  In addition, some distribution channels have higher costs associated with
  sales. As a result, the mix of distribution channels may adversely affect
  operating income.

- - Fluctuations in demand for our products and services, especially by our major
  customers. Because we are highly dependent on sales to a relatively small
  numbers of customers, changes in demand from those customers can have a
  disproportionately large effect on our revenues and results of operations. For
  example, direct and indirect product sales to, and services performed for,
  Lucent constituted approximately 47% of our total revenues in 1998 and 30% in
  the first quarter of 1999. If Lucent's demand for our products in 1999 or in
  future years were to decline, our revenues would suffer.

- - Expiration of favorable supply or purchase contracts. For example, we
  currently have a supply agreement with Lucent under which we are the exclusive
  supplier through June 2001 of Lucent's requirements for stand alone network
  access products for resale. As a result, Lucent must purchase these products
  from us. Direct and indirect sales of these products to Lucent accounted for
  approximately 46% of our total revenues in 1998 and 29% in the first quarter
  of 1999. After the expiration of the agreement, we may be unable to negotiate
  a new supply agreement. If we are unable to negotiate a new supply agreement,
  Lucent could enter into a supply agreement with another party or purchase
  these products from multiple providers. In either case, our sales of these
  products would decline substantially.

- - Costs relating to possible acquisitions and integration of technologies or
  businesses. The costs to acquire technologies and businesses is substantial.
  In addition to the direct costs, there are significant indirect costs related
  to integration of personnel and technologies and potential product redesign.
  These costs may decrease operating income or increase operating loss if they
  are not offset by comparable increases in revenue.

     In addition conditions in the telecommunications market, including
consolidation in the industry, and economic conditions generally could adversely
affect both our revenues and costs. Due to these and other factors,
period-to-period comparisons should not be relied upon as indications of future
performance. It is possible that in some future periods, our operating results
and/or our growth rate will be below what public market analysts and investors
expect.

                                        6
<PAGE>   11

WE MAY NOT ACHIEVE REVENUE GROWTH OR PROFITABILITY

     We cannot be certain that we will continue to achieve revenue growth or
realize sufficient revenues to achieve profitability. Excluding a one-time gain
in connection with a contract renegotiation with Lucent in 1997 and the related
tax effect, we had an accumulated net deficit of approximately $37.2 million
during the period from August 1, 1996 through December 31, 1998. We have not
been profitable in any fiscal year of operations except in 1997 when we were
profitable as a result of the non-recurring gain in connection with the
renegotiation of a contract with Lucent. We anticipate that we will continue to
incur significant product development and selling, general and administrative
expenses and, as a result, we will need to generate higher revenues to achieve
and sustain profitability on an annual basis.

OUR DEPENDENCE ON ONLY A FEW MAJOR CUSTOMERS FOR A SUBSTANTIAL PORTION OF OUR
REVENUES EXPOSES US TO FINANCIAL RISKS

     We depend on a small number of customers for a substantial portion of our
revenues. As a result, a loss or a significant reduction or delay in sales to
any of our major customers could materially and adversely affect our revenues.
Direct product sales to Lucent and services performed for Lucent in 1998
accounted for approximately 35% of our total revenues. Sales to Tech Data
Corporation, a distributor, in 1998 accounted for approximately 15% of our total
revenues. We estimate that approximately 70% of our sales to Tech Data
represented products that were resold to Lucent. Collectively, we estimate that
direct and indirect sales to, and services performed for, Lucent accounted for
approximately 47% of our total revenues in 1998 and 30% in the first quarter of
1999. Sales to SITA, an NSP, in 1998 accounted for approximately 9% of our total
revenues in 1998 and 8% in the first quarter of 1999, and sales to Rhythms, also
an NSP, accounted for approximately 6% of our total revenues in 1998 and 24% in
the first quarter of 1999. Unless and until we diversify and expand our customer
base, our future success will significantly depend upon certain factors which
are not within our control, including:

     - the timing and size of future purchase orders, if any, from our larger
       customers;

     - the product requirements of our customers;

     - the financial and operational success of our customers; and

     - the success of our customers' services deployed using our products.

     Diversification and expansion of our customer base is particularly critical
because of the highly competitive nature of our business. Our contracts are
generally subject to annual renewal with the exception of our contracts with
Lucent and several other customers, which have two to five year terms, and our
customers generally do not have any obligation to purchase products solely from
Paradyne. Under a supply agreement between Lucent and Paradyne, Paradyne is the
exclusive supplier of Lucent's requirements for stand alone network access
products, such as our FrameSaver products, for resale through June 2001.

WE COMPETE IN HIGHLY COMPETITIVE MARKETS AND COMPETITION COULD HARM OUR ABILITY
TO SELL PRODUCTS AND SERVICES

     The telecommunications market is highly competitive. We compete directly
with other providers of broadband and narrowband access equipment. If we are
unable to compete effectively in the market for our products or services, our
revenue and future profitability could be materially and adversely affected. We
believe that competition may increase substantially as the introduction of new
technologies, deployment of broadband networks and potential regulatory changes
create new opportunities for established and emerging companies in the industry.
We expect that competition for products that address the broadband access market
will grow as more established and new companies focus on this market.

     Many of our current and potential competitors are larger than we are and
have significantly greater financial, sales and marketing, technical,
manufacturing and other resources and more established channels of distribution.
As a result, these competitors may be able to respond more rapidly to new or
emerging technologies and changes in customer requirements, or to devote greater
resources to the development,

                                        7
<PAGE>   12

promotion and sale of their products. Our competitors may enter our existing or
future markets with solutions that may be less costly, provide higher
performance or additional features or be introduced earlier than our solutions.

     Our markets are characterized by increasing consolidation both within the
data communications sector and by companies combining or acquiring data
communications products and technology for delivering voice-related services, as
exemplified by the recently announced acquisitions of Ascend by Lucent, Diamond
Lane by Nokia and Xylan by Alcatel. We cannot be sure of the impact of any of
these acquisitions on the competitive environment for our products. Increased
competition and consolidation could result in price reductions and a decrease in
our market share.

OUR DEPENDENCE ON DEVELOPMENT RELATIONSHIPS COULD THREATEN OUR ABILITY TO SELL
PRODUCTS

     Our success is dependent upon our continued relationship with certain
companies, including AG Communications Systems, Ascend, GlobeSpan, NetScout and
Xylan. If any of these companies breaches or terminates its agreement or fails
to perform its obligations under its agreement, we might not be able to sustain
or grow our business. In particular, if any of these companies, other current
corporate partners or future corporate partners discontinue their support of
products that we have developed in cooperation with them, fail to continue to
develop product enhancements required to meet customer demand, fail to
appropriately address performance issues related to products that we have
developed in cooperation with them, face claims of infringement of third party
intellectual property rights with respect to the technology included in products
that we have developed in cooperation with them or fail to continue to support
joint marketing programs, our ability to sell products that we have developed in
cooperation with them would be hampered. Additionally, in the event that any of
our significant relationships are terminated, we may not be able to replace them
in a timely manner, if at all.

     For a further discussion of our corporate development relationships with AG
Communications Systems, Ascend, GlobeSpan, NetScout and Xylan please refer to
"Business -- Corporate Development Relationships."

OUR ABILITY TO SUSTAIN OR GROW OUR BUSINESS MIGHT BE HARMED IF WE LOSE SALES OF
ACCESS PRODUCTS TO LUCENT

     We have a relationship with Premisys Communications through which we have
exclusive distribution rights through April 2005 for Premisys' IMACS system,
which we market to Lucent and AT&T under the name Acculink Access Controller. We
have also entered into a supply and exclusivity agreement with Lucent under
which we are the exclusive supplier of Lucent's requirements for various access
products, such as the Acculink Access Controller, for resale through June 2001.
Sales of Acculink Access Controller accounted for greater than 10% of our total
revenues during each of 1997 and 1998. Our revenues would be adversely affected
if Premisys fails to meet its obligations under the agreement or if Lucent or
AT&T were to substantially reduce or discontinue their orders of Acculink Access
Controller.

     For a further discussion of our marketing and distribution relationship
with Premisys please refer to "Business -- Sales, Marketing and Distribution."

WE DEPEND ON SOLE AND SINGLE SOURCE SUPPLIERS WHICH EXPOSES US TO POTENTIAL
SUPPLY INTERRUPTION

     We currently purchase a number of important parts, such as framers,
semiconductors and embedded communications processors, from sole source vendors
for which alternative sources are not currently available. Delays or
interruptions in the supply of these components result in delays or reductions
in product shipments. The purchase of these components from outside suppliers on
a sole source basis subjects us to risks, including the continued availability
of supplies, price increases and potential quality assurance problems. We
currently purchase key components for which there are currently no immediate
substitutes available from approximately 45 vendors. All of these components are
critical to the production of our products. While alternative suppliers may be
available to us, we must first identify these suppliers and qualify them. We
cannot be certain that any such suppliers will meet our required qualifications
or that we will be able to identify alternative suppliers in a timely fashion,
if at all. We may not be able to obtain sufficient
                                        8
<PAGE>   13

quantities of these components on the same or substantially the same terms.
Consolidations involving suppliers could further reduce the number of
alternatives for us and affect the cost of such supplies. An increase in the
cost of such supplies could make our products less competitive with products
which do not incorporate such components. Lower margins or less competitive
product pricing could materially and adversely affect our business, financial
condition and results of operation.

OUR SALES CYCLE IS TYPICALLY LONG AND UNPREDICTABLE

     Our business is subject to lengthy sales cycles. As a result, we may not
recognize revenues from the sale of our products for long periods of time.
Delays in product testing or approval, or cancellations of orders by customers,
especially our NSP customers, could materially and adversely affect our
revenues. On average, our sales cycle ranges from six to nine months. Sales of
our products require a substantial commitment of capital and time from our
customers, many of whom have lengthy internal procedures for approving large
capital expenditures and lengthy testing and decision-making processes. Before
our NSP customers purchase products from us, they must first make a decision to
standardize their service on a particular product, which involves extensive
testing. Our sales cycle may be slowed further, or affected by, budgetary
constraints and purchasing requirements of our customers, all of which are
beyond our control. Moreover, sales of our products often require significant
training of both our customers and end users before the decision to purchase. As
a result, we may expend significant resources pursuing potential sales
opportunities that will not be consummated.

BECAUSE OF OUR LONG PRODUCT DEVELOPMENT PROCESS, WE INCUR SUBSTANTIAL EXPENSES
BEFORE WE EARN ASSOCIATED REVENUES

     In order to remain competitive, we invest significant resources toward
research and development of our current and potential products. Development
costs and expenses are incurred before we generate any revenues from sales of
products resulting from these efforts. Our current or future customer base may
not purchase any products resulting from our current or future development
efforts.

A FAILURE BY US TO PROTECT OUR TECHNOLOGY MAY ADVERSELY AFFECT OUR ABILITY TO
COMPETE

     Our success and ability to compete is substantially dependent upon our
technology. A failure to protect our technology could result in competitors
offering similar products potentially resulting in a loss of competitive
advantage and decreased revenues. We rely on a combination of patent, trademark,
copyright and trade secret laws and non-disclosure agreements to protect such
technology. Currently, we hold over 155 United States patents and have over 100
United States patent applications pending. In addition, we hold certain
corresponding foreign patents and have certain corresponding foreign patent
applications pending. However, we cannot be certain that patents will be issued
with respect to any of our pending or future patent applications. In addition,
we do not know whether any of our issued patents will be upheld as valid or that
they will prevent the development of competitive products.

     We seek to protect our intellectual property rights by limiting access to
the distribution of our software, documentation and other proprietary
information. If any third parties infringe our proprietary rights, such
infringement could materially and adversely affect our competitive positions. As
with our issued patents, we cannot be certain that the steps we have taken to
protect our intellectual property will adequately prevent the misappropriation
of any of our technology. Our competitors may independently develop technologies
that are substantially equivalent or superior to our technologies. In addition,
the laws of certain foreign countries do not protect our proprietary rights to
the same extent as do the laws of the United States. Third parties may attempt
to copy or reverse engineer aspects of our products or to obtain and use
information that we regard as proprietary. Accordingly, we may not be able to
protect our proprietary rights against unauthorized third-party copying or use.

     We are also subject to the risk of adverse claims and litigation alleging
infringement of the intellectual property rights of others. These claims may
require us to enter into license arrangements or may result in protracted and
costly litigation, regardless of the merits of such claims. We may not be able
to obtain necessary licenses on commercially reasonable terms, if at all. From
time to time, we receive and have

                                        9
<PAGE>   14


received letters from others requesting licenses or indicating that our products
may require a license. These letters are not uncommon in the industry, and these
letters are dealt with according to normal business practices. For example, in
March 1999, we received a letter from a third party patent owner alleging
infringement by us of patents allegedly relating to equipment, including bar
code scanners and circuit board manufacturing equipment, which we use in our
manufacturing processes, and to integrated circuit microchips that we buy and
incorporate into our products. We purchase this equipment and the microchips
from vendors, who we believe may have an obligation to indemnify us in the event
that the equipment and microchips infringe the patents. The patents referenced
in this letter are also the basis for several infringement lawsuits commenced by
the patent owner to which we are not a party. In some of those claims, the
defendants are in the process of challenging the validity of the patents. No
claim has been asserted beyond this letter, but we cannot assure you that the
third party will not commence an infringement action against us. We are in the
process of investigating the allegations. If an infringement claim is brought
against us, we cannot assure you that we would prevail and any adverse outcome
could require us, among other things, to pay royalties to the third party patent
owner. Based on our investigation to date, we presently do not believe that any
such adverse outcome would have a material adverse impact on our operations.
However, we cannot assure you that future developments will not affect this
conclusion or assure you that we will not receive other letters alleging
infringement in the future.


IF WE ARE UNABLE TO ATTRACT AND RETAIN KEY PERSONNEL AND A SKILLED WORKFORCE, WE
MAY NOT BE ABLE TO SUSTAIN OR GROW OUR BUSINESS

     Our success depends to a significant degree upon the continued
contributions of the principal members of our sales, engineering and management
personnel, many of whom would be difficult to replace. The loss of such
personnel could materially and adversely affect our business, financial
condition and results of operations. Specifically, we believe that our future
success is highly dependent on our senior management, and in particular on
Andrew May, President and Chief Executive Officer. Except for agreements with
Messrs. May, Murphy and Slattery, we do not have employment contracts with our
executive officers. In any event, employment contracts would not prevent key
personnel from terminating their employment with us.

     We believe that our future success will also depend highly upon our ability
to attract and retain highly-skilled customer support and product development
personnel. The market for qualified personnel in the telecommunications industry
is highly competitive, and we frequently experience difficulty in recruiting
qualified personnel. Recruiting qualified personnel is an intensely competitive
and time-consuming process.

OUR RELIANCE ON INTERNATIONAL SALES MAY MAKE US SUSCEPTIBLE TO GLOBAL ECONOMIC
FACTORS, FOREIGN TAX LAW ISSUES AND CURRENCY FLUCTUATIONS

     We currently have 11 sales offices and subsidiaries in North America,
Europe and Asia through which we market and sell our products. International
sales accounted for approximately 20% of our total revenues in 1998. Our
international operations subject us to risks to which we would not otherwise be
exposed. These risks may cause our results of operations to fluctuate. For
example, sales to customers outside of the United States accounted for
approximately 30% of revenues in 1997 and 20% of revenues in 1998, respectively.
This decrease was primarily due to the decline in sales of our older narrowband
products and economic instability in Asia. Our international operations subject
us to risks to which we would not otherwise be exposed, such as:

     - impact of recessions in economies outside of the United States;

     - currency exchange rate fluctuations;

     - political and economic instability;

     - policy, legal, regulatory or other changes affecting the
       telecommunications and data communications markets;

     - uncertain intellectual property rights protection;

     - potential adverse tax consequences;

                                       10
<PAGE>   15

     - change in tariffs; and

     - difficulties in accounts receivable collection.

OUR FAILURE TO COMPLY WITH REGULATIONS COULD AFFECT OUR PRODUCT OFFERINGS

     We are subject to a significant number of communications regulations and
standards, some of which are evolving as new technologies are deployed and due
to ongoing judicial and administrative proceedings. New regulations or new
interpretations of existing laws or regulations, or compliance with additional
existing regulations due to changes in the nature of our products could result
in significant additional cost to Paradyne. Moreover, failure of our products to
comply, or delays in compliance, with the various existing and evolving industry
regulations and standards could delay the introduction of our products. Our
products may be required to comply with various regulations, including those
promulgated by the Federal Communications Commission ("FCC"), state public
utilities commissions and various foreign governments. Our products must comply
with the Communications Act of 1934 and the Telecommunication Act of 1996. In
the United States, in addition to complying with FCC regulations, our products
are required to meet certain safety requirements. For example, NSPs may require
that our products that are located in their facilities be network equipment
building standard certified before they purchase the products from us. Outside
of the United States, our products are subject to the regulatory requirements of
each country in which the products are manufactured or sold. These requirements
vary widely, and we may be unable to obtain on a timely basis, or if at all,
necessary approvals for the manufacture, marketing and sale of our products.

     Enactment by federal, state or foreign governments of new laws or
regulations, changes in the interpretation of existing laws or regulations or a
reversal of the trend toward deregulation in the telecommunication industry
could materially and adversely affect our customers, and thereby materially and
adversely affect our business, financial condition and results of operations.
For a further discussion of the impact of governmental regulations on the
telecommunications industry, please refer to "Business -- Government
Regulations."

CHANGES TO REGULATIONS AFFECTING THE TELECOMMUNICATIONS INDUSTRY COULD REDUCE
DEMAND FOR OUR PRODUCTS

     If our NSP customers are required to comply with new laws, new regulations
or new interpretations of existing laws or regulations, or if they are required
to comply with additional existing regulations due to changes in the nature of
their services, those changes could materially and adversely affect the market
for our products. A large percentage of our customers are NSPs whose voice
services, and many of their other network services, must comply with the
Communications Act of 1934, the Telecommunications Act of 1996 and regulations
prescribed by the FCC. Furthermore, most of our NSP customers' voice services
are subject to regulation by state public utilities commissions. Some of our NSP
customers are subject to foreign government regulation. Many of these federal,
state and foreign regulations continue to evolve due to ongoing judicial and
administrative proceedings, particularly those federal regulations designed to
define rights and obligations under the Telecommunications Act of 1996. For
example, the FCC is considering changes to its regulations, including those
relating to the access to copper telephone lines, the ability of customers to
install equipment at an NSP's central location and the compatibility
requirements placed upon equipment which may be run on copper telephone lines.
Furthermore, the United States Congress is considering a variety of amendments
to the Communications Act of 1934 and the Telecommunications Act of 1996.

COMPLIANCE WITH EVOLVING INDUSTRY STANDARDS COULD ADVERSELY AFFECT OUR PRODUCT
OFFERINGS

     Many of our products must comply with equipment standards adopted by
national and international standards bodies. If we are required, or deem it
otherwise necessary or advisable, to comply with new standards or with
additional existing standards due to changes in standards, we may have to modify
our current or future products. The costs of any modification could materially
and adversely affect our business, financial condition and results of
operations. Compliance with these standards is important because it often
enhances the marketability of our products. Many of those standards are
influenced by industry committees

                                       11
<PAGE>   16

that develop draft standards and technical reports. These industry committees
often include us, our customers, and our competitors and their customers.

WE RELY HEAVILY ON DISTRIBUTORS AND RESELLERS

     We estimate that in 1998 over 70% of our sales were made through
distributors and resellers. We often rely on distributors and resellers to
provide installation, training and customer support to the ultimate end users of
our products. As a result, our success depends on the continued sales and
customer support efforts of our network of distributors and resellers. Any
reduction, delay or loss of orders from our significant distributors or
resellers could materially and adversely affect our revenues.

OUR ABILITY TO SUSTAIN OR GROW OUR BUSINESS MAY BE HARMED IF WE ARE UNABLE TO
PROVIDE ADEQUATE CUSTOMER SUPPORT

     Our ability to continue to grow our company and to retain current and
future customers depends in part upon the quality of our customer support
operations. A failure to offer adequate customer support could materially and
adversely affect our reputation or cause demand for our products to decline. Our
customers generally require significant support and training prior to the
installation and deployment of our products. Providing adequate levels of
support to our customers, requires significant expenditures of resources and
capital. As the market for high speed access devices grows and as the technology
for these devices continues to evolve, we will need to augment and improve upon
our customer support operations.

WE MAY NOT BE ABLE TO FINANCE OUR GROWTH AND CAPITAL REQUIREMENTS

     Substantial working capital is required in order to fund and continue to
build our business. If we fail to do so, we will not be able to remain
competitive or continue to meet the increasing demands for our products. We
expect to use the net proceeds of this offering to repay indebtedness and for
general corporate purposes, including working capital and capital expenditures.
We may also need to spend significant amounts of cash to fund operating losses
and increases in expenses, take advantage of opportunities or respond to
developments or competitive pressures. We believe that the proceeds of this
offering, together with our existing capital resources and our revolving line of
credit facility with BankAmerica NT&SA, will allow us to meet our capital
requirements for at least the next 18 months. However, our capital requirements
depend on several factors, including the rate of market acceptance of our
products, the ability to expand our client base, the growth of our sales and
marketing efforts and other factors. If capital requirements vary materially
from those currently planned, we may require additional financing sooner than
anticipated. We cannot be certain that additional financing will be available to
us when needed or that such financing can be obtained on terms favorable to us.
If adequate funds are not available or are not available on acceptable terms, we
may be unable to develop or enhance our services, take advantage of future
opportunities or respond to competitive pressures.

WE RELY UPON DISTRIBUTIONS, DIVIDENDS AND LOANS FROM OUR SUBSIDIARIES IN ORDER
TO MEET OUR OBLIGATIONS AND COMMITMENTS

     As a holding company, we have no operations of our own. If our subsidiaries
are unable to pay dividends or make loans or other distributions to us, we may
not be able to meet obligations and debts that we incur, and the market price of
our common stock could be adversely affected. In connection with a line of
credit facility, our operating subsidiary Paradyne Corporation and its Canadian
subsidiary are restricted from paying dividends and making loans and other
distributions. For a further description of these restrictions, please see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

THE YEAR 2000 PROBLEM MAY SEVERELY DISRUPT OUR BUSINESS, FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

     As is true for most companies, the Year 2000 problem creates a risk for us.
Some computers, software and other equipment include programming code in which
calendar year data is abbreviated to only two digits

                                       12
<PAGE>   17

(e.g., 99) rather than four digits (e.g., 1999). As a result, these systems
automatically assume that the first two digits of a calendar year are "1" and
"9." Therefore, time-sensitive functions of these systems may misinterpret dates
after January 1, 2000, to refer to the twentieth century rather than the
twenty-first century (i.e., "02" could be interpreted as "1902" rather than
"2002"). The problems associated with this design decision are commonly referred
to as the "Millennium Bug," "Year 2000 problem" or "Y2K problem." If systems do
not correctly recognize date information when the year changes to 2000, there
could be an adverse impact on our operations. The risk exists primarily in three
areas:

     - systems we use to run our business;

     - systems used by our service providers, distributors and suppliers; and

     - the potential for failures of our products, particularly our central
       office-based systems, due to Year 2000 problems associated with products
       manufactured by other equipment vendors used in conjunction with our
       products.

     A disruption in the operations of parties with whom we interact could
materially and adversely affect our business, financial condition and results of
operations.

     Substantial uncertainty remains in the software industry concerning the
potential effects associated with the Year 2000 problem. We have developed a
comprehensive multi-year plan to ensure that our internal computer software and
hardware systems will be Year 2000 compliant. While we believe that we have
implemented a comprehensive plan for addressing the Year 2000 problem and
anticipate completing our compliance activities in a timely manner, we cannot be
certain that these Year 2000 compliance efforts will be successful. Furthermore,
the financial impact of making the required systems changes cannot be known
precisely at this time.

     We are currently developing contingency plans to be implemented as part of
our efforts to identify and correct Year 2000 problems affecting our internal
systems. We expect to complete these contingency plans by the end of the third
quarter of 1999. Depending on the systems affected, these plans could include
accelerated replacement of affected equipment or software, increased work hours
for our personnel or use of contract personnel to correct on an accelerated
schedule any Year 2000 problems which may arise, the provision of manual
workarounds for information systems, and other similar approaches. If we are
required to implement any of these contingency plans, such plans may materially
and adversely affect our business, financial condition and results of
operations. Additionally, we may not complete these contingency plans in a
timely manner, and failure to do so could materially and adversely affect our
business, financial condition and results of operations.

IF OUR PRODUCTS CONTAIN DEFECTS, WE MAY BE SUBJECT TO SIGNIFICANT LIABILITY
CLAIMS FROM OUR CUSTOMERS AND THE END-USERS OF OUR PRODUCTS AND INCUR
SIGNIFICANT UNEXPECTED EXPENSES AND LOST SALES

     Our products are complex and, despite extensive testing, may therefore
contain undetected errors or failures. If this happens, we may experience delay
in or loss of market acceptance and sales, product returns, diversion of
research and development resources, injury to our reputation or increased
service and warranty costs. We also have exposure to significant liability
claims with respect to our customers because our products are designed to
provide critical communications services. Although we attempt to limit such
exposure through product liability insurance and through contractual limitations
in our customer agreements, such precautions may not cover all potential claims
resulting from a defect in one of our products.

MANAGEMENT AND OUR SINGLE LARGEST STOCKHOLDER MAY LIMIT YOUR ABILITY TO
INFLUENCE THE OUTCOME OF DIRECTOR ELECTIONS AND OTHER STOCKHOLDER MATTERS

     Our executive officers, directors and principal stockholders and their
affiliates will beneficially own 24,961,062 shares or approximately 79.68% of
our outstanding shares of common stock (76.80% if the underwriters'
over-allotment option is exercised in full) after the offering. As a result,
these stockholders, if acting together, would be able effectively to control
substantially all matters requiring approval by our stockholders.
                                       13
<PAGE>   18

     Entities associated with Texas Pacific Group will own approximately 57.23%
of Paradyne after the offering and will be able to exercise control over
Paradyne, subject to the fiduciary duties of its representatives on the board of
directors under Delaware law. The interests of Texas Pacific Group may not
always coincide with the interests of other stockholders. Texas Pacific Group,
through its representatives on the board of directors, could cause us to enter
into transactions or agreements which we would not otherwise consider absent
Texas Pacific Group influence. Texas Pacific Group also is currently the
majority owner of GlobeSpan. See "Certain Transactions."

OUR STOCK PRICE MAY BE VOLATILE AND YOU MAY NOT BE ABLE TO RESELL SHARES AT OR
ABOVE THE OFFERING PRICE

     There has not been a public market for our common stock prior to this
offering, and a liquid trading market for our shares may not develop following
this offering. The initial price for the shares of our common stock to be sold
in the offering will be determined by negotiations between us and the
representatives of the underwriters and may not be indicative of prices that
will prevail in the trading market. The trading price of our common stock could
be subject to wide fluctuations in response to various factors, some of which
are beyond our control, such as:

     - actual or anticipated variations in quarterly results of operations;

     - changes in intellectual property rights of Paradyne or our competitors;

     - announcements of technological innovations;

     - the introduction of new products or changes in product pricing by
       Paradyne or our competitors;

     - changes in financial estimates by securities analysts;

     - announcements of significant acquisitions, strategic partnerships, joint
       ventures or capital commitments by us or our competitors; and

     - additions or departures of key personnel.

A FAILURE TO MANAGE OUR GROWTH COULD ADVERSELY AFFECT OUR BUSINESS

     We have experienced expansions and contractions of our operations in the
past. If we are unable to manage our growth effectively, our future
profitability could be adversely affected. We anticipate that expansion of our
operations will be required to address the potential growth in our client base
and the opportunities in the broadband access market. Our current expansion is
placing a significant strain on our managerial, operational and financial
resources. We may not have adequate resources to support our future operations.

WE MAY ENGAGE IN ACQUISITIONS, AND WE MAY BE UNABLE TO SUCCESSFULLY INTEGRATE
ANY NEW OPERATIONS, TECHNOLOGIES, PRODUCTS OR PERSONNEL

     Recently, the telecommunications industry has experienced substantial
mergers and acquisitions activity. We have engaged in discussions in the past
with third parties concerning potential acquisitions of product lines,
technologies and businesses. However, we currently have no commitments or
agreements with respect to any such acquisition. In the event that such an
acquisition does occur, because of the small size of our management team, we may
be particularly susceptible to risks associated with the assimilation of
operations, technologies, products and personnel and the diversion of
management's attention from other business concerns.

SHOULD WE SELL A SUBSTANTIAL NUMBER OF SHARES OF OUR COMMON STOCK IN THE PUBLIC
MARKET,
THE PRICE OF OUR COMMON STOCK COULD FALL

     Sales of a substantial number of shares of our common stock in the public
market after this offering could cause the market price of our common stock to
decline and could impair our ability to raise additional capital through the
sale of equity securities. Upon completion of this offering, we will have
approximately 30,312,508 shares of common stock outstanding, of which
approximately 6,000,000 shares offered hereby (approximately 6,900,000 shares if
the underwriters' over-allotment option is exercised in full) will be freely
transferable without restriction or registration under the Securities Act,
unless such shares are held by our

                                       14
<PAGE>   19

affiliates, as that term is defined in Rule 144 under the Securities Act. The
remaining 24,312,508 shares of common stock held by existing stockholders as of
May 15, 1999 will be "restricted securities" as that term is defined in Rule 144
(the "Restricted Securities"). Shares totaling 24,230,906 will be subject to
"lock-up" agreements on the effective date of this offering. Upon expiration of
the lock-up agreements 180 days after the effective date of this offering, all
of these shares will become eligible for sale, subject in most cases to the
limitations of Rule 144 and Rule 701. Restricted shares held by non-affiliates
will be eligible for sale under Rule 144(k) without volume and manner of sale
restrictions. In addition, we intend to file a registration statement on Form
S-8 with the Securities and Exchange Commission covering the 7,250,000 shares of
common stock reserved for issuance under our 1996 Equity Incentive Plan, 1999
Employee Stock Purchase Plan and 1999 Non-Employee Directors' Stock Option Plan.
On the date 180 days after the effective date of this offering, at least
2,157,445 shares will be subject to immediately exercisable options (based on
options outstanding on May 15, 1999). Sales of a large number of any of these
shares could have an adverse effect on the market price for our common stock.

OUR CORPORATE CHARTER AND BYLAWS MAY DISCOURAGE TAKE-OVER ATTEMPTS AND DEPRESS
THE MARKET PRICE OF OUR STOCK

     Provisions in our restated certificate of incorporation and bylaws may have
the effect of delaying or preventing a change of control or changes in our
management. These provisions include:

     - the right of the board of directors to elect a director to fill a vacancy
       created by the expansion of the board of directors;

     - the ability of the board of directors to alter our bylaws without
       obtaining stockholder approval;

     - the requirement that at least 50% of the outstanding shares of common
       stock are needed to call a special meeting of stockholders;

     - the division of the board of directors into three classes, with each
       class serving staggered three-year terms; and

     - the requirement that all actions by stockholders must be effected at a
       duly called meeting of the stockholders and may not be effected by a
       consent in writing.

     These provisions could discourage take-over attempts and could adversely
affect the market price of our common stock. In addition, these provisions may
limit the ability of stockholders to remove our current management. In addition,
our board of directors can issue up to 5,000,000 shares of preferred stock
without the approval of the holders of common stock. Any preferred stock may
have rights senior to the common stock. The issuance of preferred stock could
adversely affect the voting power of holders of common stock and reduce the
likelihood that such holders will receive dividend payments and payments upon
liquidation. Such issuance could have the effect of decreasing the market price
of the common stock. The issuance of preferred stock could also have the effect
of delaying, deterring or preventing a change in control of Paradyne. See
"Description of Capital Stock" for a further discussion of these provisions.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements. All statements
regarding future events, our future financial performance and operating results,
our business strategy and our financing plans are forward-looking statements. In
some cases, you can identify forward-looking statements by terminology, such as
"may," "will," "should," "expect," "intend," "plan," "anticipate," "believe,"
"estimate," "predict," "potential" or "continue," the negative of such terms or
other comparable terminology. These statements are only predictions. Known and
unknown risks, uncertainties and other factors could cause actual results to
differ materially from those contemplated by the statements. In evaluating these
statements, you should specifically consider various factors, including the
risks outlined under "Risk Factors." These factors may cause our actual results
to differ materially from any forward-looking statement.

     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. We are under no duty to update any of the
forward-looking statements after the date of this prospectus to conform such
statements to actual results or to changes in our expectations.

                                USE OF PROCEEDS

     We estimate that we will receive net proceeds of approximately $47,360,000
from the sale of 4,000,000 shares of our common stock in this offering, assuming
an initial public offering price of $13.00 and after deducting estimated
underwriting discounts and commissions and offering expenses. We will not
receive any proceeds from the shares sold by the selling stockholder in this
offering.

     We intend to use the net proceeds of this offering to repay all outstanding
indebtedness under our $35,000,000 revolving line of credit facility with Bank
of America NT&SA. Our credit facility expires on January 31, 2000 and carries a
variable interest rate which was 7.75% as of March 31, 1999. As of March 31,
1999, the outstanding balance under the credit facility was approximately $10.4
million. We intend to use the remainder of the net proceeds for general
corporate purposes, including working capital and capital expenditures. The
amounts actually expended for working capital purposes may vary significantly
and will depend on a number of factors, including the amount of our future
revenues and the other factors described under "Risk Factors." Accordingly, we
will retain broad discretion in the allocation of the net proceeds of this
offering. Additionally, we may use a portion of the net proceeds to pursue
possible acquisitions of businesses, technologies or products complementary to
our business. We are not currently evaluating any acquisition opportunities and
we cannot assure you that we will identify suitable acquisition candidates or
that we will consummate any acquisitions. Pending our use of the net proceeds,
we intend to invest the funds in short term, interest-bearing, investment-grade
securities. Another primary purpose of this offering is to create a public
market for our common stock and facilitate our future access to public capital
markets.

                                DIVIDEND POLICY

     We currently anticipate that we will retain all of our future earnings for
use in the operation and expansion of our business and do not anticipate paying
cash dividends in the foreseeable future. Our current financing arrangements
place certain restrictions on the payment of dividends.

                              COMPANY INFORMATION

                                    DILUTION

     Our net tangible book value as of March 31, 1999 was approximately $31.5
million, or approximately $1.20 per share. This is calculated as our total
tangible assets less total liabilities, divided by the number of shares
outstanding as of March 31, 1999. "Adjusted net tangible book value" per share
represents our net tangible book value after adjusting for the net proceeds from
the sale of 4,000,000 shares of common stock offered hereby at an assumed
initial public offering price of $13.00 per share. The sale of shares of common
stock in this offering and the application of the net proceeds therefrom will
result in an immediate increase in net tangible book value of $47.4 million or
$1.41 per share to existing stockholders and an immediate dilution of $10.39 per
share to investors purchasing shares of common stock in this offering. The
following table illustrates this per share dilution:

     The following table summarizes, on an as adjusted basis for the offering,
as of March 31, 1999, the number of shares of common stock purchased from
Paradyne, the total consideration paid to Paradyne and the average price per

     In the event that we issue additional shares of common stock in the future,
purchasers of common stock in this offering may experience further dilution.

     The foregoing discussion and tables assume no exercise of any stock options
at a weighted average exercise price of $3.35 per share as of March 31, 1999. To
the extent these options are exercised, new investors will experience further
dilution. See "Management -- 1996 Equity Incentive Plan."

                      SELECTED CONSOLIDATED FINANCIAL DATA

    The following selected consolidated financial data is derived from the
consolidated financial statements of Paradyne and from the books and records of
its predecessor business. This data should be read in conjunction with
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" contained elsewhere in this prospectus. The consolidated statement
of operations for the seven months ended July 31, 1996, the five months ending
December 31, 1996 and for the years ended December 31, 1997 and 1998 and the
consolidated balance sheet as of December 31, 1996, 1997 and 1998 are derived
from audited consolidated financial statements. The consolidated statements of
operations data for the three months ended March 31, 1998 and 1999 are derived
from the unaudited consolidated financial statements of Paradyne, which are
included elsewhere herein. The unaudited consolidated financial information
reflects all adjustments (consisting only of normal recurring adjustments) that
the Company considers necessary for a fair statement of the financial data for
such period. The results of operations of the three months ended March 31, 1999
are not necessarily indicative of results to be expected in any future period.
The selected consolidated financial data for the years ended December 31, 1994
and 1995 have not been audited. The predecessor business consists of certain
operating activities of AT&T Paradyne Corporation, a wholly-owned subsidiary of
Lucent Technologies Inc., on a carve-out basis, which were acquired by Paradyne
effective July 31, 1996. In the opinion of our management, the predecessor
business operated in a substantially different organizational structure and
manner than we do and, accordingly, we believe that a comparison of its
operating activities and results to ours is not meaningful. See Note 2 of the
Notes to the Consolidated Financial Statements of Paradyne for an explanation of
the method used to calculate earnings per share. Earnings per share data is not
presented for the predecessor business since the predecessor business did not
have its own capital structure. As a result, this information would not be
meaningful.

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

     The following discussion should be read in conjunction with the
consolidated financial statements and the related notes contained elsewhere in
this prospectus. The following discussion contains forward-looking statements
that involve risks and uncertainties. All statements regarding future events,
our future financial performance and operating results, our business strategy
and our financing plans are forward-looking statements. In many cases, you can
identify forward-looking statements by terminology, such as "may," "will,"
"should," "expects," "intends," "plans," "anticipates," "believes," "estimates,"
"predicts," "potential" or "continue," or the negative of such terms and other
comparable terminology. These statements are only predictions. Known and unknown
risks, uncertainties and other factors could cause our actual results to differ
materially from those projected in the forward-looking statements. In evaluating
these statements, you should specifically consider various factors, including,
but not limited to, those set forth under "Risk Factors" and elsewhere in this
prospectus.

OVERVIEW

     We are a leading developer, manufacturer and distributor of broadband and
narrowband network access products for network service providers ("NSPs") and
business customers. We offer solutions that enable business class, service level
managed, high-speed connectivity over the existing telephone network
infrastructure and provide for cost-effective access speeds of up to 45 Mbps.
Our equipment has been sold to over 50% of the Fortune 500 companies and in
businesses in over 125 countries. We estimate that sales to NSPs represented
approximately 40% of our total revenues in 1998. With our reputation and history
as a supplier of access solutions to a large customer base, we believe that we
are well-positioned to provide broadband access solutions to NSPs and business
customers as they upgrade their networks.

     In July 1996, as part of a divestiture by Lucent, Paradyne Acquisition
Corp., a wholly-owned subsidiary of Communication Partners, L.P., a limited
partnership controlled by the Texas Pacific Group, acquired all of the
outstanding shares of common stock of Paradyne Corporation. In June 1999
Paradyne Acquisition Corp. changed its name to Paradyne Networks, Inc. Our
business was created when operations of Paradyne Corporation were either
retained by Lucent or assigned to newly created entities in connection with the
divestiture. The business that remained with Paradyne Corporation is referred to
as the predecessor business. The predecessor business derived most of its
revenues through July 1996 from the sale of narrowband products. The predecessor
business purchased products and services from preferred suppliers of AT&T and
Lucent and incurred intercompany charges for services provided by other AT&T
operations. Following the 1996 acquisition, we introduced a series of new
products, including many new broadband products, and discontinued sales of the
Tellabs 74X family of products which were transitioned to Lucent. In addition,
we lowered our expenses and restructured our operations. The cost of the
restructuring was accounted for as part of the purchase accounting associated
with the 1996 acquisition. We believe the revenues and expenses of the
predecessor business are not representative of our current business, financial
condition or results of operations. Accordingly, we believe that a
period-to-period comparison of operating results prior to 1997 is not
meaningful.

     In 1997, Paradyne recorded a restructuring charge of approximately $1.8
million. Most of this charge related to staff reductions in our U.S. operations
in November 1997. Staff reductions were appropriate as a result of improved
operating efficiencies resulting from an investment in new systems and processes
as well as changing the composition of our workforce to update the availability
of strategic skills. During 1998, we also incurred expenses of $1.0 million,
related to a restructuring of our international operations.

     Through 1997, our revenues were derived principally from the sale and
service of narrowband network access products and, to a much lesser extent,
technology licensing. In 1998, our broadband products, including our Hotwire and
FrameSaver products, which were introduced in 1997, comprised the majority of
our revenue, and we expect broadband products to represent an increasing portion
of future revenues. Royalty revenues consist principally of licensing of
technology, and service revenues are derived from repair of

                                       20
<PAGE>   25

out-of-warranty products. We do not expect that either royalty or service
revenues will constitute a substantial portion of our revenues in future
periods.

     We market and sell our products worldwide to NSPs and business customers
through a multi-tier distribution system that includes direct sales, strategic
partner sales, NSP sales and traditional distributor or value added reseller
sales. Direct sales to Lucent in 1998 accounted for approximately 35% of our
total revenues. Sales to Tech Data accounted for approximately 15% of our total
revenues. We estimate that approximately 70% of our sales to Tech Data
represented products that were resold to Lucent. Collectively, we estimate that
direct and indirect sales to Lucent accounted for approximately 47% of our total
revenues in 1998 and 30% in the first quarter of 1999. This percentage reduction
principally results from lower Lucent equipment sales of some of our older
products in the first quarter of 1999. A majority of our sales to Lucent
represented sales to Lucent as a reseller of our products. Sales to SITA in 1998
accounted for approximately 9% of our total revenues in 1998 and 8% in the first
quarter of 1999, and sales to Rhythms accounted for approximately 6% of our
total revenues in 1998 and 24% in the first quarter of 1999. The percentage
increase of our total revenues to Rhythms in the first quarter of 1999 is
primarily due to an increase in the deployment of their infrastructure using our
products. A loss or a significant reduction or delay in sales to any of our
major customers could materially and adversely affect our business, financial
condition and results of operations. See "Risk Factors -- We Depend on Major
Customers for a Substantial Portion of Our Revenues."

     We generally recognize revenue from product sales upon shipment. No revenue
is recognized on products shipped on a trial basis. Estimated sales returns
based on historical experience by product are recorded at the time the product
revenue is recognized. Charges for warranty work are included in cost of
equipment sales. We believe that our accrued warranty reserve is sufficient to
meet our responsibilities for potential future warranty work on products sold.
Revenue from services, which consists mainly of repair of out-of-warranty
products, is recognized when the services are performed and all substantial
contractual obligations have been satisfied. License and royalty revenues are
recognized when we have completed delivery of technical specifications and
performed substantially all required services under the related agreement.

     We expect our gross margin to be affected by many factors, including
competitive pricing pressures, fluctuations in manufacturing volumes, costs of
components and sub-assemblies, and the mix of products or system configurations
sold and timing of sales of follow-on line cards and endpoints for central
office systems. Follow-on line cards and endpoints are components that are sold
separately from central office systems and margins vary on these products.
Central office systems are often sold as stand-alone chassis with limited number
line cards. Customers purchase follow-on line cards and endpoints in order to
increase the capacity of their central office system. Additionally, our gross
margin may fluctuate due to changes in our mix of distribution channels. Sales
prices of some of our products have decreased recently as a result of increased
competition. Further price reductions may be necessary to remain competitive.
Although we have been able to offset most price declines with reductions in our
manufacturing costs, there can be no assurance that we will be able to offset
further price declines with cost reductions.

     Research and development expenses primarily consist of: personnel costs
related to engineering and technical support; consultant and outside testing
services fees; research and development facilities expenses; equipment and
supplies expenses associated with enhancing existing products and the
development of new products; an allocation of information systems charges; and
software and software maintenance expenses. We expense all research and
development expenses as incurred. We believe that continued investment in
research and development is critical to attaining our strategic product and
cost-reduction objectives. We will, however, attempt to control and optimize our
research and development expenditures in order to meet our strategic goals while
at the same time allowing us to meet our profitability goals. Over time, as
revenues increase, research and development expenditures are expected to
increase as well.

     We had twelve in-process research and development projects, consisting of
nine broadband and three narrowband projects that were acquired in connection
with the 1996 acquisition. These projects included three Acculink projects, one
Comsphere project, three Frame Relay projects, three Hotwire projects and two
digital

                                       21
<PAGE>   26

service unit projects. We acquired the in-process research and development
projects in order to gain additional product enhancements, technologies and
skills, through which we would enter into new markets and distribution channels
and grow our market share for high speed access products. At the time of the
divestiture, we estimated the value of each in-process project to range from
$0.1 million to $3.2 million, and the aggregate value to be approximately $13.1
million and anticipated that each project would require between five and nine
months to complete. Based on our technological expertise and experience in
completing and commercializing access products, we did not believe there were
any material risks that would affect the timely completion of the projects. The
total cost to complete the development of these projects at the time of the
acquisition was estimated to be approximately $15.2 million. Subsequent
developments have demonstrated that most of the projects have met or exceeded
the initial valuation placed on such projects. Three projects have proven to be
less successful than originally forecast primarily due to unforeseen changes in
the marketplace.

     Selling, general and administrative expenses primarily consist of:
salaries, commissions and related expenses for personnel engaged in marketing,
sales and field service support functions, finance, human resource and
administrative activities; advertising, promotional and trade show expenses,
including the related travel expenses; consultant fees; equipment and facilities
expenses, including intangibles amortization; supplies, software and software
maintenance; and consignments. We intend to continue to invest in selling,
marketing and promotional programs. In addition, we expect to expand our field
sales operations and customer support organizations. We expect general and
administrative expenses to increase moderately as our business grows and we
begin operations as a public company. General and administrative expenses have
been significantly reduced since the 1996 acquisition by improving systems and
processes and eliminating unnecessary expenses, and we expect to continue our
focus on controlling expenses in the future.

     Sales to customers outside of the United States accounted for approximately
30% and 20% of revenues in 1997 and 1998, respectively. This decrease was
primarily due to the decline in sales of our older narrowband products and
economic instability in Asia. In 1998, approximately 94% of our sales were
denominated in U.S. dollars. While Paradyne is subject to fluctuations in
foreign currency exchange rates with respect to income derived from
international sales not denominated in U.S. dollars, the costs associated with a
majority of these sales are in the same currency, which partially mitigates the
effect of such fluctuations. Historically, currency exchange movements have not
had a material effect on our business, financial condition or results of
operations. If our non-U.S. operations expand, the effect of currency
fluctuations may have a more significant impact on our revenues and costs. At
December 31, 1998, we had no material monetary assets, liabilities or
commitments denominated in currencies other than U.S. dollars. We do not hedge
foreign currency transactions. Our strategy for managing currency risk is to
minimize our foreign currency exposure.

     Despite growing revenues, excluding a non-recurring gain recognized in 1997
in connection with a contract renegotiation, we have not been profitable on an
annual basis, and we may continue to incur net losses. In addition to the
customer concentration we have experienced, we also have lengthy development and
sales cycles for our products, and there is often a significant delay between
the time we incur expenses and the time we realize the related revenue. To the
extent that future revenues do not increase significantly in the same periods in
which operating expenses increase, our operating results will be adversely
affected. See "Risk Factors -- Various Factors Could Cause Our Results to
Fluctuate" and "-- We May Not Achieve Revenue Growth and Profitability."

     Paradyne's quarterly and annual operating results have fluctuated in the
past and are likely to fluctuate in the future due to a variety of factors, many
of which are outside of our control. Some of these factors include:

     - the timing and amount of, or cancellation or rescheduling of, orders for
       our products and services to existing and new customers;

     - our ability to develop, introduce, ship and support new products and
       product enhancements and manage product transitions on a timely basis;

     - announcements, new product introductions and reductions in price of
       products offered by our competitors;

                                       22
<PAGE>   27

     - our ability to achieve cost reductions;

     - our ability to obtain sufficient supplies of sole or limited source
       components for our products;

     - the ability of our NSP customers to raise financing to purchase our
       products;

     - the timing and rate of deployment of our products by NSPs;

     - preferential pricing arrangements;

     - our ability to attain and maintain production volumes and quality levels
       for our products;

     - the mix of products sold and the mix of distribution channels through
       which they are sold;

     - fluctuations in demand for our products and services, especially by our
       major customers;

     - expiration of favorable supply or purchase contracts;

     - costs relating to possible acquisitions and integration of technologies
       or businesses; and

     - conditions in the telecommunications market, including consolidation in
       the industry, and economic conditions generally.

     Due to these and other factors, quarterly and annual revenues, expenses and
results of operations could vary significantly in the future, and
period-to-period comparisons should not be relied upon as indications of future
performance. Additionally, due to all of the foregoing factors, it is possible
that in some future periods, our operating results and/or our growth rate will
be below what public market analysts and investors expect. If that happens, the
market price of our common stock could decline materially.

THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THREE MONTHS ENDED MARCH 31, 1998

     Revenues.  Total revenues increased $11.0 million, or 25.6%, to $54.1
million for the first three months of 1999 from $43.0 million for the first
three months of 1998. This increase was primarily due to an increase in the
volume of sales of our broadband access products. As a percentage of total
revenues, equipment sales were 94.3% of total revenues for the first three
months of 1999 compared to 99.1% for the first three months of 1998. The
percentage decrease is mostly due to a $2.6 million increase in royalty income
which includes $1.1 million from a one-time royalty fee from GlobeSpan related
to termination of an existing agreement, and $1.5 million from a one-time
license fee from a third party for intellectual property relating to narrowband
technology.

     Gross Margin.  Gross margin increased $3.1 million, or 14.8%, to $24.1
million for the first three months of 1999 from $21.0 million for the first
three months of 1998. A substantial portion of the increase was due to the
recognition of $2.6 million of royalty revenues. Gross margin as a percentage of
total revenues decreased to 44.6% in 1999 from 48.8% in 1998 primarily because
our newer, competitively priced products comprised a greater portion of our
total revenues. Gross margin for equipment sales increased $0.4 million
reflecting increased sales at lower margins resulting from the competitive
pricing of recently introduced products.

     Research and Development Expenses.  Research and development expenses
increased $0.2 million, or 2.5%, to $8.8 million for the first three months of
1999 from $8.6 million in the first three months of 1998. As a percentage of
total revenues, research and development expenses decreased to 16.2% in the
first three months of 1999 from 19.9% in the first three months of 1998. This
decrease is primarily attributable to the increase in revenues during the
period.


     Selling, General and Administrative ("SG&A") Expenses.  SG&A expenses
increased $0.5 million, or 3.4%, to $13.9 million in the first three months of
1999 from $13.4 million in the first three months of 1998. The increase is
primarily due to increases in incentive based expenses of $0.3 million (due to
the increase in revenues), consignment of equipment to customers of $0.3 million
and higher information systems expense of $0.3 million, offset in part by a
reduction in advertising of $0.3 million and fees of $0.2 million. SG&A expense
as a percentage of total revenues decreased to 25.6% in the first quarter of
1999 from 31.2% in the first quarter of 1998 primarily due to the 25.6% increase
in revenues during the period.



     Interest and Other (Income) Expense, Net.  Interest and other (income)
expense, net, increased by $2.9 million to income of $2.4 million for the first
three months of 1999, from expense of $0.5 million for the first three months of
1998. Interest and other (income) expense, net, is related to interest on notes
payable and borrowings under lines of credit, gains and losses on equity
investments and foreign exchange gains and losses. This increase was primarily
attributable to Paradyne's recognition of approximately $3.0 million of income
from the sale of patents . Interest expense also decreased by $0.1 million in
1999 due to a reduction in the debt related to Lucent and Communications
Partners, L.P.


YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

     Revenues.  Total revenues increased $17.5 million, or 9.7%, to $198.8
million in 1998 from $181.3 million in 1997. This increase was primarily due to
an increase in the sales of our broadband access products. The increase in sales
was primarily a result of higher average selling price due to product mix and to
volume increases in broadband products. As a percentage of total revenues,
equipment sales were 98.2% in 1998 compared to 98.1% in 1997. In 1998 and 1997,
we also earned relatively small amounts of service revenues through the repair
of out of warranty equipment and royalty revenues from the licensing of
technology.

     Gross Margin.  Gross margin increased $0.4 million, or 0.5%, to $90.3
million in 1998 from $89.8 million in 1997. Gross margin as a percentage of
total revenues decreased to 45.4% in 1998 from 49.5% in 1997 for the following
reasons:


     - some of our older products faced competitive price pressures, which
       resulted in lower average sales prices and accounted for a decline in
       gross margin of approximately 3 percentage points out of the 4.1
       percentage point net decline in gross margin; and

     - In 1997 we had a large one-time customer purchase of an out-of-production
       product for which we were able to obtain a substantially higher than
       average sales price. No similar purchase occurred in 1998, resulting in a
       decrease in gross margin of 1 percentage point out of the 4.1 percentage
       point net decline in gross margin.

     Research and Development Expenses.  Research and development expenses
decreased $2.2 million, or 5.9%, to $35.1 million in 1998 from $37.3 million in
1997. This decrease was primarily due to a reduction in the number of
contractors and a decrease in employees, as a result of the restructuring in
November 1997. Research and development expenses declined to 17.7% of total
revenues in 1998 from 20.6% in 1997 primarily due to the increase in total
revenues in 1998 along with the expense reductions.

     Selling, General and Administrative Expenses.  SG&A expenses decreased
$10.3 million, or 15.6%, to $56.0 million in 1998 from $66.3 million in 1997.
The decrease was primarily attributable to a $6.4 million reduction in
amortization expense related to the Lucent settlement, a $3.3 million reduction
in consultant fees and a $2.4 million decrease in advertising costs, offset by a
$0.9 million increase in personnel costs and a $0.9 million increase in rental
expenses. SG&A expenses as a percentage of total revenues decrease to 28.2% in
1998 from 36.6% in 1997 primarily due to the increase in total revenues in 1998
along with expense reductions.

     Restructuring Charges.  During 1998, we incurred expenses of $1.0 million,
or 0.5% of total revenues, related to restructuring our international
operations.

     Interest and Other (Income) Expense, Net.  Interest and other (income)
expense, net, decreased $3.1 million, or 51.3%, to $2.9 million in 1998 from
$6.0 million in 1997. Interest and other (income) expense, net, is related to
interest on notes payable and borrowings under lines of credit, gains and losses
on equity investments and foreign exchange gains and losses. The decrease in
1998 was primarily attributable to a reduction in interest expense associated
with the $63.0 million forgiveness of debt by Lucent in 1997.

     Income Taxes.  Our 1998 income tax benefit was $1.1 million, or 22.9% of
the loss before income tax of $4.7 million. The tax benefit was less than the
statutory federal and state income tax rates principally due to losses incurred
in foreign jurisdictions for which no income tax benefit was available.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO THE SEVEN MONTH PERIOD ENDED JULY 31,
1996 (PREDECESSOR BUSINESS) AND THE FIVE MONTH PERIOD ENDED DECEMBER 31, 1996

     References to the seven month period ended July 31, 1996 and the five month
period ended December 31, 1996 (the "1996 Periods") reflect the combination of
the predecessor business for seven months of 1996 with the operations of
Paradyne for five months of 1996, and do not include any adjustments related to
the purchase.

     Revenues.  Total revenues decreased $63.2 million, or 25.9%, to $181.3
million in 1997 from $244.5 million in 1996. This decrease was primarily due to
the following factors:

     - sales of our older narrowband products, overall, declined at a rapid
       rate;

     - in an attempt to meet their 1996 contractual targets, Lucent purchased
       products from us at the end of 1996, which resulted in lower Lucent
       purchases in 1997 as it sold off its inventory (See "Certain
       Transactions"); and

     - we discontinued selling Premisys products through channels other than
       Lucent and AT&T and discontinued selling other network access products
       which were transitioned to Lucent after the sale of Paradyne.

     As a percentage of total revenues, equipment sales were 98.1% in 1997 and
98.3% in the 1996 Periods. We also earned relatively small amounts of service
revenues through the repair of out of warranty equipment and royalty revenues
from the licensing of technology.

                                       25

     Gross Margins.  Gross margin decreased $19.4 million, or 17.7%, to $89.8
million in 1997 from $109.2 million in the 1996 Periods. Gross margin as a
percentage of total revenues increased to 49.5% in 1997 from 44.6% in the 1996
Periods for the following reasons:

     - we were able to reduce the material costs of some of our products by
       obtaining more competitive pricing from our existing and new suppliers,
       which resulted in savings in the form of lower product costs in 1997, and
       we were able to obtain a higher average sales price for some of our older
       products due to increased sales of products with higher margin
       configurations, which translated into higher margins. Together these
       changes accounted for an increase of approximately 7 percentage points
       out of the 4.9 percentage point net increase in gross margin.

     - one of our major customers making a large one-time purchase of an
       out-of-production product in 1997 for which we were able to obtain a
       substantially higher than average sales price (resulting in an increase
       to gross margin of approximately 1 percentage point out of the 4.9
       percentage point net increase in gross margin.)

     - we introduced new, competitively priced access products, which resulted
       in a decrease in gross margin of approximately 4 percentage points out of
       the 4.9 percentage point net increase in gross margin.

     Research and Development Expenses.  Research and development expenses
decreased $21.9 million, or 36.9%, to $37.3 million in 1997 from $59.2 million
in the 1996 Periods. Research and development expenses declined to 20.6% of
total revenues in 1997 from 24.2% in the 1996 Periods. This decrease was
primarily attributable to recognition of purchased research and development of
$13.1 million at the time of the 1996 acquisition and a $7.7 million reduction
associated with a reduction in the number of support personnel and contractors
as a result of the restructuring in November 1997.

     Selling, General and Administrative Expenses.  SG&A expenses decreased $6.1
million or 8.4%, to $66.3 million in 1997 from $72.3 million in the 1996
Periods. This decrease was primarily due to a reduction in personnel following
the 1996 acquisition and $10.3 million associated with a reduction of SG&A
related personnel and contractors in the fourth quarter of 1997 as a result of
the November 1997 restructuring, which more than offset the $4.1 million
increase in amortization primarily due to the Lucent supply contract. SG&A
expenses as a percentage of total revenues increased to 36.6% in 1997 from 29.6%
in the 1996 Periods. This increase was primarily attributable to the reduction
of revenues in 1997.

     Restructuring Charges.  In the fourth quarter of 1997, we incurred a
restructuring charge of $1.8 million, or 1.0% of total revenues. This
restructuring was necessary to reduce redundant headcount and bring operating
expenses in line with revenues.

     Interest and Other (Income) Expense, Net.  Interest and other (income)
expense, net, increased $3.9 million, or 196.5%, to $6.0 million in 1997 from
$2.0 million in the 1996 Periods. Interest and other (income) expense, net, is
related to interest on notes payable and borrowings under lines of credit, gains
and losses on equity investments and foreign exchange gains and losses. The
increase in 1997 was primarily attributable to interest expense associated with
the Lucent debt.

     Lucent Settlement Gain.  As a condition to the closing of the 1996
acquisition, Paradyne entered into a volume purchase letter agreement, whereby
Lucent agreed to purchase minimum levels of network access products from us. At
December 31, 1997, Lucent had not satisfied its obligations and, therefore, was
subject to take or pay provisions contained in the volume purchase letter
agreement. However, in August 1998, Lucent and Paradyne entered into an
arrangement under which we terminated the volume purchase letter agreement,
received an exclusivity agreement with Lucent extending through June 2001 and
received $8.2 million of cash and the forgiveness of debt in the amount of $63.0
million owed to Lucent by Paradyne. This resulted in the recording of a $51.2
million non-recurring gain in 1997, which is net of the $16.4 million
unamortized cost of the agreement. See "Certain Transactions."

     Income taxes.  In 1997, as a result of the Lucent settlement gain of $51.2
million, we were able to utilize our net operating loss carryforwards reducing
our federal and state income tax provision to $8.3 million or 28.0% of pretax
income.

LIQUIDITY AND CAPITAL RESOURCES

     From our inception through December 31, 1998, we financed our operations
through a combination of debt financing and cash generated from operations. In
connection with the 1996 acquisition, Communication Partners, L.P. acquired the
predecessor business through an equity investment of $17.1 million. In addition,
we incurred acquisition debt totaling $76.8 million and acquisition costs of
$8.4 million. Additionally, in July 1996 we entered into a $45.0 million
revolving line of credit facility with Bank of America NT&SA. This facility was
voluntarily reduced to $35.0 million in March 1999. Following the closing of
this offering, we expect to pay any outstanding balance under the revolving line
of credit in full.

     Availability under this facility is the lesser of $35.0 million or the sum
of 85% of eligible trade accounts receivable and the lesser of: $6.0 million,
40% of the value of eligible inventory, or the amount of the machinery and
equipment appraisal. Availability is further reduced by a $3.0 million borrowing
base reserve, in lieu of any financial covenants. The line of credit facility is
secured by substantially all of our assets and contains non-financial covenants
and restrictions as to various matters, including our ability to pay dividends
or to effect mergers or acquisitions, incur other indebtedness or to make
investments without the bank's prior approval. As of March 31, 1999, we were not
in breach of any of these restrictive covenants.

     This facility, which terminates on January 31, 2000, bears an annual
interest rate of Bank of America NT&SA's reference rate plus 0 - 100 basis
points, depending on our quarterly fixed charge coverage ratio. The facility
also provides for an unused line fee of 0.375% to 0.50%. The principal amount
outstanding at December 31, 1998 was $16.1 million. The weighted average
interest rate was 9.2% for the year ended December 31, 1998.

     In August 1997, Communication Partners, L.P. agreed to provide a revolving
line of credit facility in the maximum amount of $5.0 million. This agreement
was amended in October 1998 to increase the maximum amount of the facility to
$10.0 million. Amounts outstanding may be repaid and reborrowed at any time
during the term of the note that matures on August 25, 2002. Borrowings under
this agreement are subordinated to debt under the Bank of America NT&SA line of
credit facility and bear interest at 8% per annum. The agreement does not impose
specific financial covenants upon Paradyne. It is our intention to terminate
this facility upon completion of this offering.

     We are a holding company with no business operations of our own. In the
event we incur obligations, we would be dependent on payments, loans, dividends
and distributions from our subsidiaries for funds to pay our obligations. The
ability of our subsidiaries to pay dividends or distributions or make loans to
us is subject to restrictions. Under the line of credit agreement, neither
Paradyne Corporation nor its Canadian subsidiary may pay dividends or make
distributions to us unless Paradyne Corporation and its subsidiaries meet
minimum financial ratios related to earnings, interest expense and total
indebtedness and obtain the prior approval of Bank of America NT&SA. The line of
credit agreement limits the aggregate payment of dividends and distributions to
fifty percent (50%) of the consolidated net income of Paradyne Corporation for
the period from August 1, 1996 to the end of the immediately preceding fiscal
quarter. The line of credit agreement also requires the prior approval of Bank
of America NT&SA for any loans Paradyne Corporation or its Canadian subsidiary
may make to us.

Three Months Ended March 31, 1999

     Cash provided by operations for the quarter ended March 31, 1999 totaled
$4.4 million and resulted primarily from $4.3 million in net proceeds from a
license of intellectual property related to modem technology and sale of
patents. Additionally, reductions in trade receivables due to revenues in the
first quarter of 1999 being 7% below fourth quarter 1998 revenues, increases in
accounts payable attributable to timing of vendor payments, offset by an
increase in inventory to meet expected April deliveries, also contributed
significantly to cash provided by operations. Total revenues decreased 7% in the
first quarter of 1999 compared to the fourth quarter of 1998 due to lower sales
of both narrowband and broadband products. This decrease principally resulted
from lower equipment sales to one of our largest customers. Cash provided by
operations was offset in part by reductions in payroll and benefit related
liabilities which reflect payments of 1998 commissions and management bonuses,
an increase in income tax receivable related to the tax benefit
                                       27
<PAGE>   32

of employee stock option exercises, and an increase in accounts receivables from
affiliates driven primarily by the $1.1 million one-time royalty fee from
GlobeSpan related to the termination of an existing agreement.

     Net cash used in investing activities for the quarter ended March 31, 1999
totaled $0.9 million and reflects capital expenditures made in support of
operations. The Company anticipates that capital requirements for the remainder
of the year will be in the range of $1.5 million to $2.0 million per quarter.

     Net cash used in financing activities for the quarter ended March 31, 1999
totaled $3.2 million primarily reflecting debt repayments on our Bank of America
NT&SA revolving credit facility of $5.6 million, offset in part by proceeds from
the exercise of stock options totaling $2.4 million. Net borrowings were not
required to fund operations and capital expenditures in the quarter. We expect
to use the proceeds from the initial public offering to pay down this debt.

     Paradyne had $2.6 million of cash and cash equivalents at March 31, 1999
that was an increase of $0.2 million from $2.4 million at December 31, 1998.
Working capital increased by $5.9 million from $8.4 million at December 31, 1998
to $14.3 million at March 31, 1999. We believe that the proceeds from this
offering, together with the cash flows from operations and borrowings under the
Bank of America NT&SA line of credit facility, will be sufficient to meet our
working capital needs for at least the next 18 months.

  Year Ended December 31, 1998

     Net cash used in operating activities was $4.6 million for the five months
ended December 31, 1996 as compared to $1.1 million for 1997. Net cash provided
by operating activities was $6.2 million for 1998. The reduction in net cash
used in operating activities for the five month period ending December 31, 1996
to 1997 was primarily driven by a reduction in accounts receivable and
inventory, net of a decrease in accounts payable, as a result of lower sales
volume as well as a reduction in the annual run rate of operating expenses after
normalizing for the 1996 non cash related write off of purchased research and
development. Net cash provided by operating activities increased $7.3 million
from 1997 to 1998 primarily as a result of a reduction in receivables reflecting
the collection of the other receivables totaling $8.2 million at December 31,
1997 in connection with the termination of the Lucent volume purchase letter
agreement offset in part by an increase in trade receivables. Trade receivables
increased due to increased sales volume offset in part by a reduction in the
time it takes to collect from customers. Other activities impacting net cash
provided by operations included reductions in operating expense, increased
accounts payable, reflecting timing of incurrence of obligations and payments to
vendors, offset by increased inventory, due to increased sales volume, as well
as an increase in income tax receivable, reflecting overpayment of income taxes
in 1998.

     Net cash (used in) provided by investing activities was ($29.0 million),
$11.6 million and ($5.1 million) for the five months ended December 31, 1996 and
the years ended December 31, 1997 and 1998, respectively. Effective July 31,
1996, Communication Partners, L.P. acquired Paradyne's net assets for $24.6
million in cash and $69.3 million in debt to seller. Net proceeds from the sale
of the Largo, Florida facility in June 1997 totaled $20.8 million. Net capital
expenditures relating primarily to the support of operations totaled $4.4
million, $9.2 million, and $5.4 million for the five month period ending
December 31, 1996, 1997 and 1998, respectively.

     Net cash provided by financing activities totaled $30.1 million for the
five months ended December 31, 1996. Net cash used in financing activities in
1997 totaled $8.7 million, as compared to $1.7 million for 1998. Communication
Partners, L.P.'s 1996 investment in Paradyne totaled $102.3 million, consisting
of a $17.1 million equity investment, $69.3 million in seller notes to Lucent,
debt to Communication Partners of $7.5 million and $8.4 million of other
acquisition costs. Borrowings under other debt obligations totalling $2.5
million and $6.0 million for the five months ended December 31, 1996 and the
year ending December 31, 1997 consisted primarily of deferred interest
associated with seller debt. Proceeds from the 1997 sale of the Largo, Florida
facility were used to retire debt of $20.8 million under various notes and the
Bank of America NT&SA revolving credit facility. Additionally, debt was further
reduced by $63.0 million as part of the Lucent settlement discussed above. Net
borrowings under our bank line of credit to fund operations, capital
expenditures and payment of other acquisition costs totaled $10.6 million and
$4.4 million for the five month period ending December 31, 1996 and the year
ended December 31, 1997. Net borrowings
                                       28
<PAGE>   33

against our bank line of credit were not required to fund operations, capital
expenditures and payment of other acquisition costs in 1998. The net borrowings
against this line in 1998 reflected the payoff of $2.7 million in seller debt.
Additionally, in 1998 we borrowed and repaid $5.0 million from Communication
Partners to cover working capital needs.

     We believe that the proceeds from this offering, together with the cash
flows from operations and borrowings under the Bank of America NT&SA line of
credit facility, will be sufficient to meet our working capital needs for at
least the next 18 months.

     Our revenues, historically, have tended to be strongest in the fourth
quarter and lowest in the first quarter of the following year. We believe this
is primarily due to the calendar year budgeting of many of our customers and to
compensation policies tending to compensate sales personnel in our distribution
channels for achieving annual quotas. Consequently, if revenue levels are below
expectations for a given quarter, operating results are likely to be
disproportionately affected when viewed by quarter since only a relatively small
portion of our operating expenses vary materially with revenues.

                                       29

     Our quarterly results are likely to vary due to a number of factors, such
as demand for our products, the size and timing of significant orders and their
fulfillment, the length of sales cycles for some of our newer products to our
larger customers, changes in our level of operating expenses, improvements in
operating efficiencies resulting from changes in systems and processes,
customers' budgeting cycles, changes in our sales incentive plans, changes in
the mix of products sold and conditions in foreign markets.

YEAR 2000 ISSUES

     Background:  Some computers, software and other equipment include
programming code in which calendar year data is abbreviated to only two digits
(e.g., 99) rather than four digits (e.g., 1999). As a result, these systems
automatically assume that the first two digits of a calendar year are "1" and
"9." Therefore, time-sensitive functions of these systems may misinterpret dates
after January 1, 2000, to refer to the twentieth century rather than the
twenty-first century (i.e., "02" could be interpreted as "1902" rather than
"2002"). The problems associated with this design decision are commonly referred
to as the "Millennium Bug," "Year 2000 problem" or "Y2K problem."

     Assessment:  In 1996 we identified the Year 2000 problem as a potential
risk to our operations. As a result, we developed a comprehensive multi-year
plan to make our internal computer software and hardware systems Year 2000
compliant. Our Year 2000 compliance plan is comprised of 3 phases: an assessment
phase; an implementation phase; and a testing phase. This plan, initiated in the
first quarter of fiscal 1997, is in the final stages of implementation. While we
believe that we have implemented a comprehensive plan for addressing the Year
2000 problem and anticipate completing our compliance activities in a timely
manner, we cannot be certain that these Year 2000 compliance efforts will be
successful. The financial impact of making the required systems changes cannot
be known precisely at this time, but we currently expect these expenses to be
less than approximately $4.0 million. The financial impact, could, however,
exceed this estimate. Nonetheless, these costs are not expected to be material
to our business, financial condition, or results of operation. To date, we have
incurred expenses of approximately $3.5 million.

     Internal Infrastructure:  We believe that we have identified all of the
major computer hardware, software applications and other calendar year dependent
equipment used in connection with our internal operations. Our Year 2000
compliance plan addresses items that must be modified, upgraded, or replaced in
order to minimize the possibility of a material disruption of our business. We
have replaced our accounting, sales, distribution and manufacturing systems with
what we believe to be a Year 2000 compliant enterprise resource planning system.
We have replaced our human resource and payroll systems application software
with what we believe to be Year 2000 compliant software, and we have replaced
our internal phone system and associated equipment with what we believe to be a
Year 2000 compliant system. Currently, we are in the process of modifying,
upgrading and replacing, as appropriate, other computer software applications,
hardware, and equipment that could potentially be adversely affected by the Year
2000 problem. We expect to complete this implementation phase by the end of the
third quarter of 1999. The fourth quarter of 1999 has been reserved for final
testing of all of our systems for compliance.

     Network Service Providers:  Our ongoing operations are dependent on the
uninterrupted service provided to us by our voice (landline and wireless), data
and Internet service vendors. We have initiated communications with our various
service providers and have received assurance that they have or will address
Year 2000 compliance issues associated with their ability to provide
uninterrupted service. Any failure of these vendors to resolve any outstanding
Year 2000 issues in a timely manner could materially and adversely affect our
business, financial condition and results of operation.

     Distributors and Suppliers:  We have initiated communications with our key
distributors, service support providers and suppliers to establish the status of
their Year 2000 compliance. We have communicated with our major suppliers of
minicomputers, servers, computers, software and other equipment used, operated
or maintained by us to identify and, to the extent possible, resolve issues
associated with the Year 2000 problem. We are also gathering Year 2000
compliance information from web sites and other public sources for our second
and third-tier distributors and suppliers. We believe that we have identified
all of the potential Year 2000 problems with respect to these distributors,
service support providers and suppliers and have

                                       30
<PAGE>   35

received their commitment to resolve any outstanding issues in a timely manner.
However, any failure on our part to identify potential third party Year 2000
problems or any failure of these parties to resolve any outstanding issues with
their systems in a timely manner could materially and adversely affect our
business, financial condition and results of operations.

     As we must rely to a large extent on representations made by our suppliers
and distributors from surveys and questionnaires, a failure by these parties to
adequately address and resolve Year 2000 problems poses the most likely
unresolved Year 2000 risk to us. In the event our suppliers are unable to
adequately address Year 2000 problems, such inability could disrupt their supply
of critical components to us for the manufacture of our products.

     Contingency Plans:  We are currently developing contingency plans to be
implemented as part of our efforts to identify and correct Year 2000 problems
affecting our internal systems. We expect to complete these contingency plans by
the end of the third quarter of 1999. Depending on the systems affected, these
plans could include (i) accelerated replacement of effected equipment or
software, (ii) increased work hours for our personnel or use of contract
personnel to correct on an accelerated schedule any Year 2000 problems which may
arise, (iii) the provision of manual workarounds for information systems and
(iv) other similar approaches. If we are required to implement any of these
contingency plans, such plans may have a material adverse effect on our
business, financial condition or results of operations. Additionally, we may not
complete these contingency plans in a timely manner, and failure to do so could
have a material adverse effect on our business, financial condition or results
and operations.

     The discussion of our efforts and expectations relating to Year 2000
compliance are forward-looking statements. Our ability to achieve Year 2000
compliance and the level of incremental costs associated with achieving this
compliance could be adversely impacted by, among other things, the availability
and cost of programming and testing resources, the ability of parties with whom
we interact to resolve Year 2000 issues and unanticipated problems identified in
our ongoing compliance review.

MARKET RISK

     We are exposed to changes in interest rates primarily from our revolving
line of credit facility with Bank of America NT&SA and, secondarily, from
investments in some held-to-maturity securities. Under our current policies, we
do not use interest rate derivative instruments to manage exposure to interest
rate changes. Additionally, we do not currently engage in foreign currency
hedging transactions to manage exposure for transactions denominated in
currencies other than U.S. dollars.

INFLATION

     Because of the relatively low levels of inflation experienced in 1996, 1997
and 1998, inflation did not have a significant effect on our results in such
years.

                                    BUSINESS

OVERVIEW

     We are a leading developer, manufacturer and distributor of broadband and
narrowband network access products for network service providers, commonly
referred to as NSPs, and business customers. Paradyne operates in a single
business segment. We offer solutions that enable business class, service level
managed, high-speed connectivity over the existing telephone network
infrastructure and provide for cost-effective access speeds of up to 45 megabits
per second, or Mbps. We believe that demand for high-speed, broadband
transmission will continue to increase as more business and residential users
find narrowband access technologies inadequate to meet their high-bandwidth
requirements. Our objective is to maintain and build upon our position as one of
the leaders in the broadband access market by focusing on next generation
digital subscriber line, more commonly known as DSL, service level management,
more commonly known as SLM, and other broadband access solutions.

     We have a long history of technological innovation, and we hold over 155
U.S. patents and have over 100 U.S. patent applications pending. Our equipment
has been sold to over 50% of the Fortune 500 companies and in businesses in over
125 countries. We estimate that sales to NSPs represented approximately 40% of
our total revenues in 1998. With our reputation and history as a supplier of
access solutions to a large customer base, we believe that we are
well-positioned to provide broadband access solutions to NSPs and business
customers as they upgrade their networks.

INDUSTRY BACKGROUND

     Over the past several years, data traffic generated by computer users
accessing the Internet or business networks has increased significantly.
Industry analysts believe that the volume of this data traffic, referred to as
wide area network traffic, will continue to expand rapidly due to four key
trends:

     - the dramatic growth in the use of the Internet;

     - the proliferation of distributed computing applications, such as
       electronic mail, electronic transaction processing, enterprise resource
       planning and inter-enterprise information transfer based on Web-
       technologies;

     - the deregulation of the telecommunications services industry which has
       increased the number of service providers and intensified competition;
       and

     - the continued deployment of high capacity fiber optic networks and the
       emergence of high-volume bandwidth network access technologies that
       increase the ability to transfer large volumes of information.

     In order to accommodate increasingly high volumes of data, NSPs have
invested significant resources to upgrade central office switching centers and
the interconnecting infrastructure, known as the network backbone. While
capacity constraints in the network backbone continue to be addressed through
the use of high speed digital and fiber-optic equipment, the network that
connects end users to NSPs central offices, typically known as the "last mile,"
remains a bottleneck that limits high-speed data transmission. The last mile was
originally constructed with copper twisted-pair wiring designed to support
analog voice traffic. There is an installed base of over 170 million copper
lines in the United States, and over 780 million worldwide. End users have been
frustrated by the limitations on the ability of NSPs to cost effectively deliver
high-speed services, such as telecommuting, branch office internetworking and
Internet access, over the last mile using standard, narrowband dial-up
connections, which are typically limited to data transmission rates of 28.8
kilobits per second, or Kbps, to 56.0 Kbps. We believe that most business and
residential users are finding these types of narrowband access technologies
inadequate to meet their high bandwidth requirements.

     Global regulatory changes are increasing the number of competitors in the
access portion of the network and are further accelerating the need for NSPs to
upgrade their networks and increase their service offerings. Internationally, a
number of developed and developing nations have privatized their state-owned
telecommuni-

                                       32
<PAGE>   37

cations monopolies and opened their markets to new NSPs. Competitors that have
emerged and potentially could take customers from incumbent carriers include
competitive local exchange carriers, often called CLECs, Internet service
providers, satellite operators, cable operators and electric utilities. For
example, cable operators are already beginning to provide data transmission
services to customers by leveraging the high bandwidth capabilities of their
coaxial cable based infrastructure. This increase in competition for the access
portion of the network is also helping to facilitate the transition from analog
to digital and narrowband to broadband access over the last mile.

     New digital technologies have been introduced to increase the speed and
quality of digital transmission over the copper wire infrastructure, or local
loop, in the last mile and provide alternative means of accessing the network
backbone. The increased speed, lower transmission cost, higher reliability and
quality of digital networks are better suited for transmitting the increased
level of enhanced voice and high-speed data traffic that now must pass over the
last mile. Recently, NSPs have begun to install higher-speed, digital broadband
transmission technologies, such as DSL, in the last mile. Dataquest forecasts
that the market for DSL equipment will grow from approximately $286 million in
1998 to over $1.6 billion by 2002.

     NSPs have deployed various narrowband and broadband technologies across
customers' wide area networks in order to provide cost-effective access
solutions for their customers. Demand for high-speed access services has
increased and more protocols have emerged to facilitate the connections of
business customers to NSPs' network backbones. Protocols are computer languages
that allow two or more communications devices, such as modems, to communicate
with one another. These protocols include Frame Relay, asynchronous transfer
mode, commonly referred to as ATM, integrated services digital network, commonly
referred to as ISDN, DSL and others. When networks must support multiple
protocols, network management is more difficult because many protocols are being
used simultaneously and the network management devices must decipher each
protocol. The proliferation of protocols makes the provisioning and management
of high-speed access technologies and services increasingly difficult. As a
result, NSPs are required to operate and maintain hybrid networks comprised of
recently adopted new technologies and existing installed equipment.

     The performance, quality and maintainability of network services are highly
dependent on the volume and type of traffic running over these hybrid networks.
As a result, NSPs and business customers need sophisticated diagnostic and
management capabilities to monitor business customer application traffic. The
required tools should analyze the physical transmission characteristics as well
as enable NSPs and business customers to evaluate compliance with service level
agreement parameters such as, how much data gets through the network, the time
it takes data to get through the network and availability of the network.
Business customers also need management solutions that can be scaled to meet
growing demand for services, improve network quality, reduce the number of
support personnel managing their networks and lower the overall costs for
bandwidth and maintenance tools.

     As demand for high-speed transmission continues to increase, we believe
that the telecommunications industry will continue to develop and deploy new
broadband access technologies, which will become increasingly cost competitive
with traditional technologies. As a result of changes in the telecommunications
industry, NSPs are requiring flexible solutions that can be scaled to meet
growing demand for services, and also permit easy, cost-effective enhancements
in the future. With the increasing number of access protocols and equipment
options, customers are placing a higher level of importance on the ability of
equipment providers to deliver integrated system solutions.

THE PARADYNE SOLUTION

     Paradyne is a leading developer, manufacturer and distributor of network
access products for NSPs and business customers. We offer solutions that enable
business class, service level managed, high-speed connectivity over the existing
telephone network infrastructure and provide for cost-effective access speeds of
up to 45 Mbps. NSPs use our broadband products to enable high-speed managed
connections from the central office to the customer premise. Moreover, our
broadband products enable NSPs to more efficiently provide network access
services by allowing a high level of management, monitoring and control over
network access equipment and circuits. Business customers use our broadband
products for high-speed connection of voice

                                       33
<PAGE>   38

and data communications to connect their employees to corporate wide area
networks and to the Internet using both public and private services provided by
NSPs. Our products are designed for easy installation by NSPs and end users,
significantly reducing the need for installation by an onsite service
technician, thereby reducing costs for network access. Additionally, our
narrowband products are used by NSPs and business customers to provide
connectivity between an NSP's analog or digital circuit and a customer's digital
equipment.

  BROADBAND SOLUTIONS

     - Broadband DSL Access.  Our Hotwire solution delivers broadband DSL access
       across the existing copper wire infrastructure. The Hotwire products
       enable competitive local exchange carriers, incumbent carriers and other
       NSPs to provide broadband access to business customers, teleworkers and
       residential customers at substantially reduced rates compared to
       conventional service offerings. We believe our Hotwire solution allows
       NSPs the ability to deploy the broadest array of DSL technologies of any
       commercially available product in a single platform. This enables NSPs to
       match the appropriate DSL technology to the customer's application
       requirements and thereby serve a wider array of customers. This also
       allows for a more efficient utilization of expensive central office
       equipment space and minimizes operational support requirements, such as
       training and inventory, by using a single vendor. The recently introduced
       SuperLine system incorporates our Tripleplay technology, a technology
       developed by Paradyne that enables multi-line voice and data service over
       a single telephone line, and allows NSPs to offer cost effective,
       multiple line voice and high speed data services over a single
       traditional telephone line to residential customers, small offices and
       home offices. The SuperLine system incorporates products and technology
       manufactured and developed by AG Communication Systems and Paradyne.
       Contractually, both AG and Paradyne have the rights to sell the entire
       system. The SuperLine product can be easily installed by customers to
       meet their broadband access needs.

                                       34
<PAGE>   39

     - Broadband SLM.  The FrameSaver solution enables competitive local
       exchange carriers, incumbent carriers and other Frame Relay service
       providers to offer managed high-speed service from end-to-end across
       their networks and across multi-carrier networks. Using packet
       technology, Frame Relay and asynchronous transfer mode networks allow for
       the economical use of the broadband network backbone. Packet technology
       allows many customers data to share the same network. Each customer's
       data is put into packets, or envelopes, that contain only their data and
       have an identification stamp that designates the customer. These packets,
       or envelopes, are then sent over a broadband network along with other
       customer's packets. These packets are able to simultaneously share the
       broadband network. However, without the use of an SLM solution, the NSP
       and the business customer are unable to proactively manage and guarantee
       the level of service across the network. The FrameSaver solution allows
       customers the ability to graphically view real time and historical
       network performance statistics and troubleshoot failures end-to-end
       across the Frame Relay network from our OpenLane network management
       system.

     - Broadband Conventional Access.  Our Acculink and NextEdge solutions
       deliver broadband access across the existing NSP infrastructure utilizing
       T1/E1 links. A T1/E1 link is a connection between two locations that
       carries data at the rate of 1.544 megabits per second (T1) or 2.048
       megabits per second (E1). The T1/E1 infrastructure is the most commonly
       deployed broadband network system today and is widely available in the
       United States. Customers often have both voice and data networks that
       were installed using multiple broadband and/or narrowband access lines. A
       single conventional broadband facility can typically accommodate up to 24
       narrowband lines. Acculink and NextEdge act as the required
       communications interface to these broadband networks and enable the
       elimination of narrowband access lines by consolidating voice and data
       over the same broadband circuit. Access consolidation reduces the cost of
       high speed access and may also increase performance, particularly when
       customers consolidate multiple narrowband access lines onto broadband
       facilities. Additionally, NextEdge incorporates FrameSaver SLM functions
       to deliver access consolidation and SLM in the same platform. Acculink
       and NextEdge solutions are used by competitive local exchange carriers,
       incumbent carriers and other NSPs to offer service level managed, high
       speed access to public and private networks. Business customers choosing
       to manage their own networks also deploy our Acculink and NextEdge
       solutions.

  NARROWBAND SOLUTIONS

     - Subrate Digital Access and Analog Modems.  Our Comsphere digital access
       products provide an interface between a customer's digital equipment and
       an NSP's digital circuit operating at speeds of up to 64 Kbps. Our
       Comsphere modems enable analog communications over dial-up or dedicated
       circuits. These products enable NSPs and business customers to build
       low-cost, centrally managed networks. Introduced in the early 1990s,
       these products are widely deployed in NSP networks and business networks
       around the world.

STRATEGY

     Our objective is to maintain and build upon our position as one of the
leaders in the broadband access market utilizing next generation DSL solutions,
conventional copper broadband solutions and SLM solutions. Key elements of our
strategy include:

  CONTINUE TO DEVELOP INNOVATIVE BROADBAND TECHNOLOGY AND SYSTEM SOLUTIONS

     We will continue to focus on providing innovative, cost-effective broadband
access solutions that improve communications over the traditional copper
telephone wire infrastructure for NSPs and business customers. We believe that
our internally developed technologies play a key role in differentiating our
products from those of our competitors. We have over 155 U.S. patents issued and
over 100 U.S. patent applications pending, and we expect many of these patents
and patent applications will contribute to the development of new technologies
and systems. In addition, we will continue to collaborate with technology
partners to facilitate the development of competitive products, as we have
previously done with NetScout, AGCS and
                                       35
<PAGE>   40

others. Our DSL technological innovations include our MVL and Tripleplay
technologies, which have been implemented in our Hotwire and SuperLine products.
Our SLM technology innovations have been implemented in our FrameSaver, NextEdge
and OpenLane products. We intend to enhance our Hotwire DSL solutions with
higher port densities, additional customer premises equipment capabilities and
additional features for our DSL access multiplexer, commonly referred to DSLAM.
Higher port densities will allow more modems to be deployed in one DSLAM which
lowers the cost of deploying a modem. The cost is lowered because more modems
can share the common cost of the DSLAM chassis and power supplies and because
customers can put more modems in the same amount of shelf space. In order to
increase customer premises equipment capabilities, we intend to build products
that allow customers to perform many functions over their DSL network. These
products could allow voice and data to share the DSL network, SLM to be deployed
over a DSL network, streaming audio and video over a DSL network or special
protocols to be transmitted over a DSL network. In order to create additional
features for our DSLAM we plan to continue to develop new versions of both
hardware and software to support new requirements from our customers. We also
intend to enhance our Tripleplay technology to support additional voice channels
and faster data speeds. Further, we intend to integrate our FrameSaver SLM
technology into additional platforms, including those that support DSL and
asynchronous transfer mode. As our customers continue to expand their DSL
networks into the application space of conventional broadband networks, we
believe our technological leadership and products provide Paradyne a competitive
advantage.

  CONTINUE TO CAPITALIZE ON BUILDOUT OF DSL INFRASTRUCTURE

     Revenues from worldwide sales of DSL equipment are projected by industry
sources to increase by approximately 275% from 1998 to 2002. To capitalize on
this projected growth, we intend to continue to pursue "design wins" from NSPs
that are offering or plan to offer DSL services. A "design win" is achieved when
an NSP adopts Paradyne products as one of a limited number of DSL platforms for
its central office. A typical NSP buildout includes DSLAMs in an NSP's central
office, resulting in an installed base into which Paradyne will be well
positioned to sell DSL line-cards for the DSLAMs and DSL customer premises
equipment for the end user. Since the third quarter of 1997, Paradyne had
shipped over 2,000 DSLAMs. Some of our current DSL customers include CFW
Communications, Guangdong PTA, HarvardNet, NAS CuNet, Rhythms, TDS Telecom and
Tunisia Telecom. We will continue to focus on increasing our number of design
wins with new NSPs as well as maintain our existing relationships with NSPs who
have awarded us design wins in the past. We also intend to continue to produce a
variety of DSL line-cards and DSL customer premises equipment to handle the
diverse needs of our NSP customers. We intend to install DSL interfaces on our
FrameSaver and NextEdge products which will allow customers to deploy those
solutions into DSL networks. We further plan to enhance our DSLAMs so that they
may be interoperable with other companies' technologies and DSL customer
premises equipment in order to provide a more comprehensive DSL solution.

  INCREASE WORLDWIDE DEPLOYMENT OF FRAMESAVER AS PART OF NSP/SLM SOLUTIONS

     NSPs are enhancing their service offerings by providing service level
agreements for their Frame Relay and asynchronous transfer mode business
customers. Service level agreements are put in place between an NSP and the
NSP's customer to document how the NSP and the customer expect the service to
operate. If the service does not operate as specified, then there is typically
some type of remedy. An example might be that the service is supposed to be
available 24 hours a day, 365 days a year. If the service is not available for
one of those days, then the NSP might be required to reimburse the customer for
one day's worth of charges. We believe that as service level agreements become
more widely adopted, NSPs and end user customers will increasingly require SLM
solutions and, therefore, that NSPs will be required to incorporate these
solutions in their networks. We intend to focus on further integrating
FrameSaver as part of our existing NSP customers' service level agreement
solutions and obtaining additional FrameSaver design wins from new NSPs.
Currently, Ameritech, Intermedia, IXC and MCI WorldCom offer FrameSaver
solutions to their customers. In addition, we intend to work with other Frame
Relay and ATM equipment vendors to leverage our FrameSaver products.

                                       36
<PAGE>   41

  FOCUS ON PRODUCT SALES TO AND THROUGH NSPS

     We intend to continue focusing on NSPs that provide managed network access
services to capitalize on the increased demand for such services. Over the past
three years, our sales to NSPs have increased as a result of the efforts of our
worldwide NSP direct sales force. We estimate that over 40% of our revenues in
1998 were generated from sales to NSPs. We intend to focus the efforts of our
direct sales force on maintaining and increasing sales within our current NSP
customer base as well as attracting new NSPs. We plan on focusing primarily on
NSPs deploying DSL, Frame Relay and second and third line voice and data
services.

  LEVERAGE FORTUNE 500 CUSTOMER BASE AS THEY UPGRADE THEIR NETWORKS TO BROADBAND

     We intend to leverage our installed base of Fortune 500 companies and other
businesses that have purchased our narrowband products and conventional
broadband products. Many of these customers have deployed networks including a
combination of our narrowband and broadband solutions, and we expect that over
the next few years many of these companies will upgrade their networks with
additional broadband solutions. We believe that our existing customers prefer to
buy broadband products from Paradyne as a result of the ability to integrate
Paradyne products into their existing networks more efficiently than the
products of our competitors. In order to capitalize on this potential equipment
upgrade within Fortune 500 companies, we intend to continue to provide
cost-effective solutions for our current customers while increasing our sales
effort with our Fortune 500 customer base.

PRODUCTS AND TECHNOLOGIES

     We develop, manufacture and distribute an extensive line of broadband and
narrowband network access products and technologies. Sales of broadband products
represented approximately 38% of our total product sales in 1997 and 53% of our
total product sales in 1998. In addition, we provide advanced network management
systems that allow business customers and NSPs to have a high level of

     Broadband DSL

     Hotwire.  The Hotwire multiservices system includes DSLAM termination
equipment, which provides aggregation of services in the central office, and an
array of customer premises equipment, which extend various broadband access
services over the local loop to the customer premise. The system supports a
range of broadband multimedia access services, such as business and residential
Internet access, remote local area networks access and virtual private network
access at symmetric rates (similar transmission rate for sending and receiving
data over the same line) of up to 1 Mbps and asymmetric rates (varying
transmission rates for sending and receiving data over the same line) of up to 7
Mbps. Hotwire also supports Frame Relay, asynchronous transfer mode T1/E1
channelized access to the wide area networks. With channelized access, customers
can send and receive voice or data traffic on different channels. For example,
channels 1-12 could be used to send data while channels 13-24 could be used to
send voice. In addition to supporting high density configurations for central
office applications, the efficient packaging for lower density market entry
applications allows Hotwire products to be deployed in a variety of private
copper networks, including multi-dwelling-units for both business and
residential access services, universities, hotels, and government campus private
networks.

     Our primary customers for Hotwire products are competitive local exchange
carriers, incumbent carriers and other NSPs. Their services are typically
focused on meeting the broadband networking requirements of business customers,
teleworkers and the small office/home office market -- often with an emphasis on

                                       39

broadband Internet access. Competitive local exchange carriers customers, such
as Rhythms, are deploying a nationwide network using our Hotwire systems.
Incumbent carriers such as North Pittsburgh Telephone are deploying Hotwire in
their local service areas. NSPs outside the United States, such as the Guangdong
PTA in China, are using Hotwire products to deliver broadband access to the
provinces they serve. The principal focus of these customers, particularly in
the early stages, is to build out central office installations. Our Hotwire
products are easily installed, scaleable and operate over long loops, which
enhance an NSP's ability to deploy them quickly and service new customers.

     We believe that the ability to support multiple access services, with a
choice of symmetric or asymmetric DSL technologies, multiple backbone
capabilities and the ability to scale to over 1,000 DSL lines per system makes
Hotwire one of the most flexible and scalable DSL systems available. We believe
this is important because our NSP customers may want to supply symmetric
services to their business customers and asymmetric services to their consumer
customers. In addition, our NSP customers may want to use asynchronous transfer
mode on some backbone connections and Frame Relay on other backbone connections.
The Hotwire system can be configured, monitored and controlled through our
OpenLane network management system that provides complete end-to-end management
and reporting coverage of the entire broadband DSL access solution.

     Hotwire products consist of two major product family categories, DSLAMs and
customer premises equipment.

     - Hotwire Multiservices DSLAMs:  A DSLAM is a DSL access multiplexer
installed in NSPs' central offices and private copper networks that provides
termination and aggregation of multiple DSL lines and associated services
protocol translation. The Hotwire Multiservices DSLAM systems consist of network
equipment building standard certified chassis and associated DSL line cards, and
an aggregation system with a variety of wide area network options and a
standards based network management system. Network equipment building standard
certification is generally necessary in order for a product to be installed in
the central office of an NSP. Key features of a Hotwire DSLAM system include:

        - the ability to support line cards that support between four and 24
          ports per card;

                                       40
<PAGE>   45

        - multiple DSLAM configurations, which include our highly-compact,
          stackable DSLAM supporting as few as 4-8 DSL lines which is scalable
          to 68 lines and our high-density DSLAM supporting as many as 432 lines
          per shelf;

        - the ability to support a range of voice and data applications that
          operate over packet technologies and channelized access technologies;

        - a broad set of available interfaces to consolidate traffic onto a
          backbone network. These interfaces operate from between 1.544 Mbps up
          to 45 Mbps and can be configured to support Ethernet, Frame Relay or
          asynchronous transfer mode. These interfaces include: 10base-T,
          100base-T, Channelized T1 and E1, Frame Relay T1 and E1 and
          asynchronous transfer mode; and

        - a simple network management protocol compliant distributed network
          management architecture that supports efficient network management
          required for large NSP network deployments.

     - Hotwire DSL customer premises equipment:  Hotwire customer premises
equipment terminates DSL access services at the customer premise for
connectivity to local area networks, personal computers, plan systems, routers
and other voice and data equipment. Hotwire customer premises equipment operates
at a variety of transmission speeds and loop lengths to meet the needs of our
customers. Hotwire customer premises equipment and associated DSLAM line cards
support multiple DSL technologies.

     We expect to continue to implement these multiple DSL technologies in our
Hotwire products, and, consistent with market requirements, to implement
additional DSL technologies, such as G.lite. Additionally, Hotwire customer
premises equipment will be enhanced to include new features required by our
customers and the general market. While we purchase some of the DSL technologies
implemented in the Hotwire DSLAM and customer premises equipment, our MVL
product represents a new DSL technology developed and implemented by Paradyne
that does not require a telephone line splitter and works over very long loops.
The primary advantages of MVL technology are:

        - simultaneous voice and data capability over copper loops up to 24,000
          feet and is not affected by multiple terminations of copper loop,
          commonly known as bridged taps, which provides for ease of customer
          installation and eliminate rewiring at the customer premise; and

        - operates using low power, which allows higher density DSLAMs which
          lowers the cost for our NSP customers.

     In March 1999, we received approval from the FCC to register Hotwire MVL
under Part 68 of the FCC's Rules for the Registration of Telephone Equipment
code. The FCC requires that all customer installed equipment that resides on the
telephone infrastructure be registered under Part 68. This approval is based on
the FCC's decision that Hotwire MVL benefits the public's interest by providing
enhanced customer choice and improved service quality for data transmission over
the public switched telephone network and does not pose a risk of harm to the
public switched telephone network. We believe that MVL is the only DSL
technology to receive such approval to date, and that the approval should allow
more customers to deploy MVL while meeting the network requirements of incumbent
carriers.

office/home office markets.

[Diagram depicting the SuperLine integrated access system connecting a
residential customer's data and multi-line voice applications over a single
copper pair to the central office. - Graphic entitled "Superline
Integrated Access Solution."
Graphic indicates that "Superline reduces the cost of adding multi-line voice
and Internet access." Graphic also lists the main features of Superline
Integrated Access Solution as having the following:

  - Regular phone line and up to two additional phone lines

  - 56 kbps modem support on additional lines

  - Consumer installation - no truck roll

  - Toll quality voice and calling features supported

  - High-speed data (up to 640 kbps)

  - Automatic quality of service for voice

  - Optimized dynamic bandwidth for data

  - Uses a single copper pair]

     SuperLine offers several advantages over other currently available
solutions through its support of as many as three telephone lines and a
high-speed Internet access connection over a single existing phone line. We
believe SuperLine is currently the only product to offer such a solution.
SuperLine provides access at rates up to 10 times faster than current narrowband
products. SuperLine can be installed by the end user simply by plugging it into
a standard telephone jack. SuperLine allows carriers to increase service
offerings without installing additional copper lines. The primary customers for
our SuperLine integrated access system are incumbent carriers, many of which are
facing a shortage of available copper wire lines and are seeking alternatives to
physically installing new lines or deriving lines with existing technologies.
The SuperLine system is also compatible with all major switching systems
currently sold in North America. Developed through a partnership with AG
Communications Systems, SuperLine integrates Tripleplay, a technology developed
by Paradyne that enables multi-line voice and data service over a single
telephone line. We also designed and manufacture the associated SuperLine
integrated access device that is distributed as part of the SuperLine system.
The NSP central office equipment included in the SuperLine system was developed
and is manufactured by AG Communications Systems. See "Corporate Development
Relationships." The SuperLine system was introduced in January 1999 and is
distributed by Lucent and AG Communications Systems.

     Broadband Service Level Management

[Diagram depicting the FrameSaver SLM products interconnecting over a Frame
Relay network and an NSP's OpenLine network management system connecting to
monitor and analyze the performance of the network by collecting the data from
the FrameSaver customer premises equipment.--Graphic entitled "Paradyne
FrameSaver--WAN Service Level Management Solution."]

     FrameSaver.  Our FrameSaver system is an innovative SLM system for Frame
Relay and Frame Relay/asynchronous transfer mode networks. The FrameSaver system
consists of customer premises equipment, NSP equipment and network management
software to monitor and measure network performance across public Frame Relay
systems. The FrameSaver system measures performance and stores the results for
retrieval by our OpenLane network management system. The storage and data
retrieval mechanisms have been implemented according to recognized industry
standards, which makes the FrameSaver system compatible and interoperable with
many other systems that business customers or NSPs may have installed. The
FrameSaver network access units also provide extensive non-disruptive diagnostic
and testing capabilities along with standard access functionality, to give
enterprise customers or service providers a complete managed solution. The
remote monitoring technology included in the FrameSaver System, called RMON-2,
was developed by NetScout and is included in the FrameSaver system pursuant to a
collaboration between Paradyne and NetScout. The significance of utilizing
RMON-2 is that it is a communications language that has been standardized.
Therefore, many different companies build products that utilize RMON-2 which
enables communication with the FrameSaver system. See "Corporate Development
Relationships."

     Key features of our FrameSaver system include:

     - extensive performance management with diagnostic and control capabilities
       that are used to identify and resolve problems quickly without disrupting
       the network;

     - standards based measurements that allow customers to measure data
       throughput both within and above their committed information rates;

     - available in a range of network access speeds, from 64 Kbps up to T3;

     - non disruptive management that can be accessed over the Frame Relay
       network or through an integrated dial modem;

                                       43
<PAGE>   48

     - the ability to install and diagnose without the presence of a router;

     - dial backup through integrated service digital network to protect against
       network failures;

     - network to network interface for SLM across multiple Frame Relay
       networks;

     - auto configuration of customer premises equipment for ease of
       installation; and

     - the ability to scale from small single customer networks to very large
       service provider networks.

     FrameSaver allows companies to build and manage data networks based on
public network services, while maintaining the same operational efficiency and
confidence used in the management of private networks. By deploying FrameSaver,
business customers can move applications from costly leased lines to shared
public networks and benefit from reduced network services costs, while
maintaining a high degree of control of the network. The FrameSaver system
enables NSPs and business customers to accurately monitor the performance of
individual customer connections across a public or private Frame Relay or Frame
Relay/ asynchronous transfer mode network and to report details of that
performance at varying time intervals.

     While competing products may offer some of the features of the FrameSaver
product, we believe that no other product on the market today offers such a wide
variety of features. With our FrameSaver solution's ability to operate
completely independent of a router, NSPs are able to manage the network
end-to-end without relying on the customer's router. Router independence is a
key differentiating feature because during installation of the circuit, the
router might not be installed and when diagnosing an operational circuit, it may
be the router that is actually causing the problem. FrameSaver offers NSPs the
ability to perform non-disruptive circuit loopback testing from their network
operations center. This FrameSaver feature allows an NSP to respond to a trouble
call within a few minutes instead of hours, saving time and personnel expense
while increasing customer satisfaction. For these reasons, management believes
that due to its comprehensive feature set, FrameSaver offers NSPs and business
customers cost savings not found in competing solutions.

     Broadband Conventional Access

[Diagram depicting the Paradyne NextEDGE solution aggregating multiple voice and
data applications over a single broadband access facility connecting to the
public switched telephone network and a Frame Relay network and providing

     Acculink and NextEdge T1/E1 digital access products consist of a range of
products that provide an interface between a T1 circuit, which carries data at
1.544 Mbps or E1 circuit, which carries data at 2.048 Mbps, and a customer's
high-speed digital equipment, such as a computer, router, multiplexer, wide area
network switch or telephone system. The Acculink and NextEdge products are
managed by our OpenLane network management system, which provides centralized
management of large, geographically disbursed networks for NSPs and businesses.
Businesses, service providers, government entities and other organizations use
these products to build low-cost, centrally managed networks for high-speed,
digital applications. Our T1/E1 digital access products provide a broad range of
features, including centralized, standards-based network management multiple
voice and data interface ports and multiplexing.

     Acculink.  Acculink products provide integrated voice and data network
access to business customers who want to take full advantage of their T1/E1
bandwidth capacity. The products are used primarily in applications where voice
and data integration over a T1 or E1 line is required. The Acculink T1/E1
products were introduced as a standard part of AT&T's High-Speed Accunet digital
services in the early 1990s, and have been deployed widely in large business
networks ever since.

     NextEdge.  The NextEdge products add the SLM capabilities of FrameSaver to
the functionality provided by the Acculink products. NextEdge products are used
by NSPs and business customers to deploy integrated voice and data services plus
managed Frame Relay services over a common T1 infrastructure. Business customers
are seeking to maintain the SLM capabilities they have come to view as essential
for their public Frame Relay services as they integrate other network services
onto available bandwidth in their T1 access lines.

  NARROWBAND SOLUTIONS

     Our Comsphere digital access products consist of a family of managed
digital service units that provide a network interface for a digital circuit
operating at up to 64 Kbps and a customer's digital equipment, such as a
computer, terminal controller, router or other narrowband digital communications
equipment. We introduced the Comsphere digital service unit in the early 1990s,
when they were offered as a standard part of AT&T's digital data services. Our
Comsphere analog modems enable communications over dial-up or dedicated analog
circuits. These analog modems are approved for use around the world and are
widely deployed in business and NSP networks. These highly managed modems
operate on both dial circuits and analog private line circuits where network
applications demand an extremely high degree of network uptime and
manageability. All of the Comsphere products are managed by our OpenLane network
management system, which provides centralized management of large,
geographically disbursed networks for NSPs and businesses.

     Businesses, service providers, government entities and other organizations
use these products to build low-cost, centrally managed networks for their
digital applications. Many of these customers have also begun installing our
Acculink, NextEdge and FrameSaver products for their broadband network access
applications. We estimate that we have shipped more than 775,000 narrowband
access products over the past five years.

NETWORK MANAGEMENT SOLUTIONS

     OpenLane.  The OpenLane network management system, a centralized management
platform, integrates OpenLane into all of our product families and provides NSPs
and business customers with the ability to manage their network access products
located at the edge of the wide area network. The OpenLane software is purchased
separately with each of our products in order to utilize OpenLane's management
capabilities. OpenLane consists of a suite of network management tools that
provide SLM and visibility into network circuits and network access unit
performance. The management tools work together to provide business customers
and NSPs with detailed, accurate performance metrics needed to understand
precisely how their network is performing and where performance problems or
potential problems may reside. The OpenLane network management system offers a
user-friendly graphical user interface and graphical reporting. OpenLane is
designed to work with Hewlett-Packard's OpenView network management platform and
is based extensively on standards, such as simple network management protocol,
which enable it to interface with

                                       45
<PAGE>   50

many third-party network management applications that our business and NSP
customers may be using. OpenLane can provide reports and access to screens
either directly or by using the Internet for web-based delivery. Recent releases
of our OpenLane software modules are based on Java programming to permit a
platform independent system. Our NSP and business customers depend on the
OpenLane network management system as the central management system they use to
monitor and control the network access products that they have deployed in their
networks.

CORPORATE DEVELOPMENT RELATIONSHIPS

     Our success is dependent upon our continued development relationships with
a number of companies with whom we have development arrangements. We expect to
continue to collaborate with technology partners to facilitate the development
of competitive products. Currently, our development relationships include the
following:

     AG Communication Systems.  In June 1998, we entered into a joint
development and distribution agreement with AGCS. Paradyne granted a
non-exclusive license to AGCS to incorporate Paradyne's Tripleplay technology
into AGCS's central office switch, digital loop carrier and/or DSLAM equipment
and distribute to sellers of telecommunications systems the products that
incorporate the Tripleplay technology. AGCS agreed to pay a license fee to
Paradyne for the Tripleplay technology. Paradyne granted AGCS a non-exclusive
right to purchase Tripleplay hardware and software for distribution, and AGCS
granted Paradyne a non-exclusive right to purchase switch products for
distribution. The agreement will expire in June 2003, unless renewed.

     NetScout.  In January 1998, we entered into a marketing and license
agreement with NetScout under which Paradyne agreed to utilize exclusively
NetScout's RMON-2 network management software with our FrameSaver Frame Relay
access unit products, to market and sell NetScout Manager Plus software with our
FrameSaver system and not to compete against NetScout with respect to RMON-2
based technology. NetScout agreed to reference Paradyne as a strategic partner
for digital service units, DSLs and multiplexers and agreed to give preference
to Paradyne when sourcing or integrating digital service units. NetScout granted
a non-exclusive license to promote, market, sell, license and distribute any
NetScout software or product embedded into Paradyne's FrameSaver products in
exchange for royalty fees to NetScout. The agreement will expire in January
2003, unless renewed.

     Xylan.  Effective March 1999, we entered into a joint development and
supply arrangement with Xylan under which Xylan granted us a non-exclusive,
worldwide right to market, distribute and sell its OmniSwitch product and
related products with our DSL products. The agreement further provides that
through at least March 2001, we are Xylan's primary reseller of these products
for connections to our DSLAMs. Paradyne and Xylan have agreed upon feature
enhancements to these products to meet specific customer requirements. The
agreement continues for two years, after which it may be automatically renewed
for successive one-year periods.

     Ascend Communications.  In November 1998, we entered into a joint
development and marketing agreement with Ascend in connection with our OpenLane
SLM software and Ascend's Navis, a network management system. Under the
agreement, we agreed to develop interface software which integrates OpenLane
with Navis, creating a single integrated solution for competitive local exchange
carriers, incumbent carriers and other NSPs. Ascend and Paradyne jointly market
Navis, together with OpenLane SLM software, to NSPs. The agreement will continue
unless terminated upon 60 days written notice.

     GlobeSpan.  Effective March 1999, we entered into a supply agreement with
GlobeSpan which provides for preferential pricing to Paradyne and other terms in
connection with the purchase of GlobeSpan products by Paradyne. Under the terms
of this agreement, GlobeSpan is required to honor Paradyne's orders for
GlobeSpan products in quantities at least consistent with Paradyne's past
ordering practices and agreed to afford Paradyne at least the same priority for
its orders as GlobeSpan affords other similarly situated customers. Paradyne was
also granted immunity under GlobeSpan's intellectual property rights for all
Paradyne customers that purchase Paradyne products that incorporate GlobeSpan
products. GlobeSpan has

                                       46
<PAGE>   51

been selling products to Paradyne pursuant to these terms since July 1998. The
agreement will expire in March 2003, unless terminated upon one year's notice.
In addition to the supply agreement, Paradyne and GlobeSpan work very closely
together to develop capabilities that are jointly defined by the two companies.
Our marketing and research and development organizations meet on a regular basis
to review the status of projects.

SALES, MARKETING AND DISTRIBUTION

     We sell our products worldwide through a multi-tier distribution system
that includes direct sales, strategic partner sales, NSP sales and traditional
distributor or value added reseller sales. Our sales teams are supported with
marketing programs, educational programs, field technical support and telephone
technical support. Our Internet and intranet sites are used extensively to
communicate with our sales teams, our customers and our resellers.

     Our direct sales teams are organized to sell directly to NSP, value added
reseller and distributor customers. Our NSP and value added reseller customers
purchase our products and then sell them or provide them in a service offering
to business customers. We support our resellers' sales activity with a demand
generation sales force. This team markets to business customers in support of
our value added reseller and NSP partners. Our resellers add value by providing
order processing, credit and significant sales and technical support. Our field
sales teams are comprised of sales and systems engineering personnel that are
experienced and knowledgeable about the products and technologies we provide and
support. Our field sales teams are further supported by Paradyne's telesales
team. This inside sales team answers all incoming emails and telephone calls,
makes outbound telephone calls, follows up on leads generated through
advertising and provides telephone support to our resellers.

     Our resellers are responsible for identifying potential business customers,
selling our products as part of complete solutions and, in some cases,
customizing and integrating our products at end users' sites. We establish
relationships with resellers through written agreements that provide prices,
discounts and other material terms and conditions under which the distributor is
eligible to purchase our products for resale. Such agreements generally do not
grant exclusivity to the resellers, prevent the resellers from carrying
competing product lines or require the resellers to sell any particular dollar
amount of our products, although the contracts may be terminated at our election
if specified sales targets and end user satisfaction goals are not attained. We
nurture these relationships with resellers with incentive and training programs.
This multi-channel sales strategy encourages broad market coverage by allowing
our sales personnel to create demand for our products while giving customers the
flexibility to choose the most appropriate delivery channels.

     We participate in trade shows and seminars and make extensive use of the
Internet and our web presence at www.paradyne.com to promote and generate demand
for our products. (The reference to our worldwide web address does not
constitute incorporation by reference into this prospectus of the information
contained at this web site.) Since most of our customers utilize the Internet,
we believe that our Internet presence is a low cost and highly effective method
for educating our customers about our products and creating demand for our
products. As a result, we place Internet advertising and conduct targeted email
marketing. Our web site includes product information, multimedia presentations
and customer testimonials. We also host Internet based interactive seminars for
promotional seminars, training events and press conferences.

     Channel marketing programs allow us to attract and support our resellers,
including NSPs. Our "Connect to Success" reseller program markets and sells
products directly to large resellers and through national distributors, such as
Ingram Micro and Tech Data, to hundreds of value added resellers and NSPs. Our
relationships with these distributors provide significant value to our reseller
partners by giving them immediate availability to product without the cost of
stocking. These well known distributors also extend credit to resellers,
increasing their buying power, and providing them with direct shipments to end
customers further reducing costs. Our reseller programs provide advertising
support, volume incentive rebates, exclusive access to technical support via 800
numbers and through our web site. Special programs encourage value added
reseller loyalty, focus on strategic products, and focus on winning new
accounts. Specialized product training programs are provided to our resellers at
our headquarters, in the field and over the web.

                                       47
<PAGE>   52

     In addition to the marketing and sale of our products, we resell the
Acculink Access Controller, our private label for the IMACS system of Premisys
Corporation, through a small, focused sales team. Paradyne and Premisys entered
into a distribution agreement in 1992, which has been amended and extended,
under which we have exclusive distribution rights through April 2005 for
Premisys' IMACS system, which we market to Lucent and AT&T. In 1995 and 1996, we
sold the Acculink Access Controller to Lucent, AT&T and many other companies. In
1997, we discontinued selling the product to customers other than Lucent and
AT&T for various pricing and distribution reasons. Currently, we sell the
Acculink Access Controller to Lucent and AT&T for a variety of wireless and
wireline applications. We have also developed and sell a limited number of
hardware and software enhancements for the Acculink Access Controller.

CUSTOMERS

     The end-users of our equipment are primarily businesses and NSPs.

  BUSINESS CUSTOMERS

greater than 10% of revenues. Direct sales to Lucent in 1998 accounted for
approximately 35% of our total revenues. Sales to Tech Data accounted for
approximately 15% of our total revenues. We estimate that approximately 70% of
our sales to Tech Data represented products that were resold to Lucent.
Collectively, we estimate that direct and indirect sales to Lucent accounted for
approximately 47% of our total revenues in 1998. Lucent purchases products to
include in their data networking solutions products, which it sells to
businesses worldwide. Lucent also purchases our products to package with their
various telephone systems. Tech Data purchases products from us as a
distributor.

CUSTOMER SUPPORT

     We maintain a strong focus on customer service and support for our
resellers and end user customers. We accomplish this at our customers' sites
through systems engineers who work with customers in a pre-sales role, and
through the support teams of our resellers. The Paradyne Technical Support
Center provides telephone based pre- and post-sales support to resellers and
customers on a seven day, 24 hour basis and also provides proposal support to
the sales organization. Our training organization provides technical training to
end users, maintenance service providers, NSPs and sales channels. Training is
included as a part of our channel programs or is provided on a fee basis.

     We provide maintenance support offerings that utilize a variety of service
organizations based on geography and skills required. Our authorized service
providers include Lucent, NCR, Myriad and TechForce. These service providers
provide service offerings that include various maintenance packages,
installation, remote management, project management and other professional
service options.

     Warranties on most of our hardware products extend for 24 months. A number
of products carry a 12 month warranty and others carry a 60 month warranty.
Software products carry a 90 day warranty. Factory repair or replacement is
provided by us.

COMPETITION

     The telecommunications market is highly competitive. If we fail to compete
effectively our business will be adversely affected. We believe that competition
may increase substantially as the introduction of new technologies, deployment
of broadband networks and potential regulatory changes create new opportunities
for established and emerging companies in the industry. We compete directly with
other providers of broadband and narrowband access equipment, including ADC
Telecommunications, Adtran, Alcatel, Ascend, Cisco, Copper Mountain, Digital
Link, Larscom, Motorola, Nokia, Nortel Networks, Orckit, PairGain, Sync
Research, 3Com, Tut Systems and Visual Networks. We expect that competition for
products that address the broadband access market will grow as more companies
and an increasing number of new companies focus on this market to develop
solutions for higher speed access to public networks. We expect that competition
for products that address the narrowband market will not dramatically change
over the course of the next few years.

     Many of our current and potential competitors are larger than we are and
have significantly greater financial, sales and marketing, technical,
manufacturing and other resources and more established channels of distribution.
As a result, these competitors may be able to respond more rapidly to new or
emerging technologies and changes in customer requirements, or to devote greater
resources to the development, promotion and sale of their products. Our
competitors may enter our existing or future markets with solutions that may be
less costly, provide higher performance or additional features or be introduced
earlier than our solutions. Some of our competitors currently offer financing
alternatives to their customers at levels at which we cannot compete.

     Our markets are characterized by increasing consolidation both within the
data communications sector and by companies combining or acquiring data
communications products and technology for delivering voice-related services, as
exemplified by the recently announced acquisitions of Ascend by Lucent, Diamond
Lane by Nokia and Xylan by Alcatel. Increased competition and consolidation
could result in price reductions and loss of market share by Paradyne. We cannot
be sure of the impact of any of these acquisitions on the competitive
environment for our products. Increased competition and consolidation could
result in price reductions and a decrease in our market share. Our future
success will depend on our ability to compete successfully against our
competitors based on the following factors:

     - key product features;

     - system reliability and performance;

     - technological innovation;

     - price;

                                       49
<PAGE>   54

     - time to market;

     - breadth of product lines;

     - conformity to industry standards;

     - ease of installation and use;

     - brand recognition;

     - ability to help customers finance purchases;

     - technical support and customer service; and

     - size and stability of operations.

RESEARCH AND DEVELOPMENT

     Since 1969, we have been developing technologies and solutions for the
communications market. We believe that our future success is dependent on our
ability to continue to rapidly deliver innovative broadband access solutions.
Time to market is critical in order to meet the requirements of our extensive
customer base and to be able to quickly adapt to the constantly emerging needs
in the market. Innovation is critical in order to provide the capabilities that
differentiate the products and solutions that we offer from those of our
competitors. We intend to maintain an ongoing investment in research and
development that will support technological innovation.

     Our research and development efforts are focused on sustaining and
enhancing our existing products and developing innovative new solutions in the
emerging broadband market. We emphasize early and frequent interaction between
our research and development systems engineers, key technologists and customers
to arrive at unique solutions to meet specific product requirements. Customer
feedback is also obtained from resellers and through participation in industry
events, organizations, and standards bodies.

     We have developed core competencies in SLM, broadband systems
internetworking, network management, and broadband access technologies. We will
continue to rely on the use of industry and technology partnerships to further
enhance the capability to quickly introduce new solutions into the broadband
market, and we expect to continue to employ a strategy that uses a combination
of internally developed solutions and external partnering.

     We maintain research and development sites in Largo, Florida and Red Bank,
New Jersey. In addition, engineering work is completed in Mexico and India
through technology partnering arrangements. In order to maintain our rapid pace
of product introduction, we will need to continue to attract talented engineers
and invest in state-of-the-art research and development tools and processes. We
will continue to invest resources in key skill areas, such as Java programming,
system software, digital signal processing, internetworking, data communication
protocols, test automation, central office solutions, RISC processing,
transmission technologies, and telephony.

     Currently, we are developing enhancements for all of our broadband and SLM
product families. We expect this work to result in feature improvements to these
products, reduce our costs associated with their manufacture or reduce the cost
to deploy them. We are focused on increasing the density of our DSL systems and
expect to introduce 12 and 24 line cards for our Hotwire DSLAM. We are also
adding SLM to products that did not previously include SLM capability, enhancing
the SLM features for those products that already support SLM and adding DSL
function to products that currently have only conventional broadband
capabilities.

INTELLECTUAL PROPERTY

     Our success and ability to compete is dependent in part upon our
proprietary technology. We rely on a combination of patent, copyright, trademark
and trade secret laws and non-disclosure agreements to protect our proprietary
technology. We currently hold over 155 U.S. patents and have over 100 U.S.
patent applications pending. In addition, we hold corresponding foreign patents
and have corresponding foreign patent applications pending. There can be no
assurance that patents will be issued with respect to pending or
                                       50
<PAGE>   55


future patent applications or that our patents will be upheld as valid or will
prevent the development of competitive products. We seek to protect our
intellectual property rights by limiting access to the distribution of our
software, documentation and other proprietary information. In addition, our
employees execute proprietary information agreements and we enter into
nondisclosure agreements with some of our strategic partners. There can be no
assurance that the steps taken by us in this regard will be adequate to prevent
misappropriation of our technology or that our competitors will not
independently develop technologies that are substantially equivalent or
independently developed technologies that are substantially equivalent or
superior to our technologies. We also are subject to the risk of adverse claims
and litigation alleging infringement of the intellectual property rights of
others. In this regard, there can be no assurance that third parties will not
assert infringement claims in the future with respect to our current or future
products or that any such claims will not require the us to enter into license
arrangements or result in protracted and costly litigation, regardless of the
merits of such claims. Furthermore, from time to time, we receive and have
received letters from others requesting licenses or indicating that our products
may require a license. These letters are not uncommon in the industry, and these
letters are dealt with according to normal business practices. For example, in
March 1999, we received a letter from a third party patent owner alleging
infringement by us of patents allegedly relating to equipment, including bar
code scanners and circuit board manufacturing equipment, which we use in our
manufacturing processes, and to integrated circuit microchips that we buy and
incorporate into our products. We purchase this equipment and the microchips
from vendors, who we believe may have an obligation to indemnify us in the event
that the equipment and microchips infringe the patents. The patents referenced
in this letter are also the basis for several infringement lawsuits commenced by
the patent owner to which we are not a party. In some of those claims, the
defendants are in the process of challenging the validity of the patents. No
claim has been asserted beyond this letter, but we cannot assure you that the
third party will not commence an infringement action against us. We are in the
process of investigating the allegations. If an infringement claim is brought
against us, we cannot assure you that we would prevail and any adverse outcome
could require us, among other things, to pay royalties to the third party patent
owner. Based on our investigation to date, we presently do not believe that any
such adverse outcome would have a material adverse impact on our operations.
However, we cannot assure you that future developments will not affect this
conclusion or assure you that we will not receive other letters alleging
infringement in the future.


     Most of Paradyne's existing patent portfolio, will be enforceable in the
United States for at least the next ten years, provided that periodic
maintenance fees are paid to the U.S. Patent & Trademark Office and unless
determined to be invalid or unenforceable by an appropriate court or the U.S.
Patent & Trademark Office. Most of Paradyne's inventions that are directed to
DSL and Service Level Management technologies are covered in pending
applications that have yet to issue as patents and that have been filed in the
last several years. If and once issued, these patents will be enforceable for 20
years from the date the application was originally filed, pursuant to applicable
laws, provided that periodic maintenance fees are paid to the U.S. Patent &
Trademark Office and unless determined to be invalid or unenforceable by an
appropriate court or the U.S. Patent & Trademark Office.

MANUFACTURING AND FACILITIES

     Our principal administrative, engineering and manufacturing facilities are
located in two leased buildings totaling approximately 333,000 square feet in
Largo, Florida. In addition, we maintain a research and development facility of
approximately 29,000 square feet in Red Bank, New Jersey. The leases for the
Largo, Florida facility and the Red Bank, New Jersey facility expire in 2007 and
2003, respectively, and there are two five-year renewal options on the Largo,
Florida facility. Additionally, there is an automatic extension of the lease
term of the Largo, Florida lease if the current landlord sells this property
within the first three years of the lease. The Red Bank lease is not renewable
but we retain the right to renegotiate with the landlord. We also lease offices
for branch sales and administration in Virginia, as well as in Canada, France,
Egypt, Japan, Hong Kong, Singapore and the People's Republic of China.
Collectively, these offices occupy approximately 27,000 square feet. Leases for
these facilities expire at various times during 1999 and 2002. We believe that
the current facilities will be able to accommodate anticipated expansion of
operations in these locations over the next 24 months.
                                       51

     We manufacture substantially all of our products. All of our major
operations are ISO-9001 registered. Many of our parts are procured from a
variety of qualified suppliers per our specification. Some of our strategic
suppliers are electronically linked, and given 26 week visibility of demand. We
believe that this is critical in maintaining high delivery volumes and
minimizing inventory. We use a combination of standard parts and components,
which are generally available from more than one vendor and some parts that are
obtained from a single source. We have generally been able to obtain adequate
supplies in a timely manner from our current vendors or, when necessary, to meet
production needs from alternative vendors. We believe that, in most cases,
alternate vendors can be identified if current vendors are unable to fulfill our
needs. However, if we are unable to obtain sufficient quantities of necessary
supplies, or if there is a significant increase in the price of key components
or materials, delays or reductions in manufacturing or product shipments could
occur, which would have a material adverse effect on our business, financial
condition and results of operations.

     We believe that we have sufficient production capacity to meet current
demand for our product offerings and anticipate meeting future demand through a
combination of the use of additional employees and increased outsourcing of
products or components. In addition, we have the right of first refusal on the
construction of any building on some lands adjacent to our Largo, Florida
facilities if more space is needed to expand our manufacturing operations.

EMPLOYEES

     As of March 31, 1999, we employed approximately 855 full time employees.
None of our employees is covered by collective bargaining agreements, and we
believe that our relations with our employees are good.

GOVERNMENT REGULATION

     In the U.S., the Telecommunications Act of 1996 changed the regulatory
environment for all NSPs, including the competitive local exchange carriers and
incumbent carriers among our customer base. The Telecommunications Act of 1996
removed federal, state and local barriers to entry into the local telephone
market by CLECs. The Telecommunications Act of 1996 also imposed significant
obligations on incumbent carriers, including obligations to interconnect their
networks with competitors' networks and to unbundle their networks and provide
competitors with access to unbundled network elements. Competitive local
exchange carriers and incumbent carriers are a significant part of our customer
base. The Telecommunications Act of 1996 also directs the Federal Communications
Commission to adopt local loop access rules to enable competitive providers of
advanced services, such as high-speed Internet access, to deploy new
technologies on a faster, more cost-effective basis to consumers. The United
States Congress is considering a variety of amendments to the Telecommunications
Act of 1996. The FCC currently is considering changes to its regulations,
including those relating to network equipment registration and the deployment of
broadband services. We cannot predict whether any amendments to the
Telecommunications Act of 1996 or any future FCC Regulations will have a
negative impact on our business or the businesses of our customers or suppliers.

     Companies selling terminal equipment to be connected to the public switched
telephone network must register some of their products with the FCC and conform
them to technical standards promulgated by the FCC in its regulations. These
regulations are designed to protect the public switched telephone network from
harm, including interference and service degradation.

LEGAL PROCEEDINGS

     We are not a party to any pending material litigation.

EMPLOYMENT AGREEMENTS


     In order to meet its obligations under an intercompany services agreement
with Paradyne Credit Corporation, Paradyne entered into a Key Employee Agreement
with Thomas E. Epley for the period beginning April 1, 1999 and ending July 31,
1999. Pursuant to the terms of the Key Employee Agreement, Mr. Epley was
entitled to an annualized base salary of $600,000. Mr. Epley was neither
eligible to participate in our 1996 Equity Incentive Plan nor was he eligible
for a discretionary or incentive bonus. During the term of this agreement, Mr.
Epley served as President and Chairman of the board of directors of Paradyne
Credit Corporation. Pursuant to the terms of the intercompany services
agreement, Paradyne Credit Corporation was required to reimburse Paradyne for
all costs related to these services. Either Paradyne or Mr. Epley had the right
to terminate Mr. Epley's employment at any time for any reason. On June 30, 1999
the Key Employee Agreement was terminated and Mr. Epley received the remainder
of his salary through July 31, 1999 as provided for in the Key Employee
Agreement. Mr. Epley continues to serve as Chairman of the board of directors of
Paradyne.


     Paradyne has an Employment Agreement with Andrew S. May dated as of October
31, 1996 and continuing indefinitely. Under the agreement, Mr. May is entitled
to receive an annualized base salary of not less than $300,000. He received a
commencement bonus in the amount of $35,000 and is eligible to receive an annual
cash bonus of up to 50% of his base salary. He is also eligible to participate
in the Amended and Restated 1996 Equity Incentive Plan. During the term of the
agreement, Mr. May is serving as President and Chief Executive Officer. Either
Paradyne or Mr. May has the right to terminate Mr. May's employment at any time
for any reason. If we terminate Mr. May's employment without cause or he resigns
for a material breach by us of his employment agreement, he will receive a
severance payment equal to one year's salary.

     Paradyne has a Key Employee Agreement with Patrick M. Murphy dated as of
August 1, 1996 and continuing indefinitely. Under the agreement, Mr. Murphy is
entitled to receive an annualized base salary of not less than $215,000. He is
eligible for a discretionary bonus in an annualized amount of up to $70,000. He
is also eligible to participate in the 1996 Equity Incentive Plan. During the
term of the agreement, Mr. Murphy is serving as Senior Vice President, Chief
Financial Officer and Treasurer. Either Paradyne or Mr. Murphy has the right to
terminate Mr. Murphy's employment at any time for any reason. If we terminate
Mr. Murphy's employment without cause, he will receive a severance payment equal
to one year's salary.

     Paradyne has a Key Employee Agreement with James L. Slattery dated as of
August 1, 1996 and continuing indefinitely. Under the agreement, Mr. Slattery is
entitled to receive an annualized base salary of not less than $189,410. He is
eligible for a discretionary bonus in an annualized amount of up to $85,000. He
is also eligible to participate in the 1996 Equity Incentive Plan. During the
term of the agreement, Mr. Slattery is serving as Senior Vice President, Chief
Legal and Intellectual Property Officer and Corporate

                                       57

Secretary. Either Paradyne or Mr. Slattery has the right to terminate Mr.
Slattery's employment at any time for any reason. If we terminate Mr. Slattery's
employment without cause, he will receive a severance payment equal to one
year's salary.

CHANGE OF CONTROL PROVISIONS

     We have an arrangement with Andrew S. May governing the vesting of stock
options upon a change in control. The agreement provides that all of Mr. May's
options shall become exercisable upon a change in control. We have arrangements
with Patrick M. Murphy and James L. Slattery governing the vesting of stock
options upon a change of control. Each agreement provides that in the event of a
change in control, 50% of the unvested options held by the officer shall become
immediately exercisable and the remaining unvested shares shall become
exercisable if the officer does not receive comparable employment following the
change of control. Furthermore, if the officer receives comparable employment,
the remaining unvested shares shall become exercisable upon the earlier of the
one year anniversary of the change in control or the officer's termination
without cause. The Company has agreed to guarantee the value of the unvested
shares equal to the value on the date of the change in control. We have an
arrangement with Sean E. Belanger governing the vesting of stock options upon a
change in control. The arrangement provides that all of Mr. Belanger's options
shall become exercisable in the event Mr. Belanger is not offered comparable
employment following a change of control, and his stock options are not either
assumed or replaced with similar stock options. Our employment agreement with
Thomas E. Epley provides that upon a change of control, Mr. Epley shall have the
right to terminate his employment and to receive an amount equal to the balance
of his base salary payable for the remaining term of this agreement.

1996 EQUITY INCENTIVE PLAN

     The Amended and Restated 1996 Equity Incentive Plan (the "1996 Plan") was
adopted by Paradyne Acquisition Corp.'s board of directors in January 1997 and
approved by its stockholders in April 1997. An amendment and restatement of the
1996 Plan was adopted by our board of directors and our stockholders in June
1999 which added the provision described below that increases the share reserve
under the 1996 Plan automatically each year and made other minor amendments to
the 1996 Plan in preparation for this offering.

     A total of 6,000,000 shares have been reserved for issuance under the 1996
Plan. Each year, the number of shares reserved for issuance under the 1996 Plan
will automatically be increased by the lesser of 4,500,000 shares or 5.0% of the
total number of shares of common stock then outstanding. The 1996 Plan provides
for grants of incentive stock options that qualify under Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), to our employees
(including officers and employee directors) or the employees of any of our
affiliates. Nonstatutory stock options, rights to acquire restricted stock, and
stock bonuses may be granted to employees (including officers), directors of and
consultants to Paradyne or any of our affiliates. The 1996 Plan may be
administered by the board of directors or a committee appointed by the Board of
Directors; references herein to the board of directors shall include any such
committee. After this offering, it is intended that the 1996 Plan will be
administered by a Compensation Committee consisting of "non-employee directors"
under applicable securities laws and "outside directors," as defined under the
Code. The board of directors has the authority to determine to whom awards are
granted, the terms of such awards, including the type of awards to be granted,
the exercise price, the number of shares subject to the awards and the vesting
and exercisability of the awards.

     The term of a stock option granted under the 1996 Plan generally may not
exceed 10 years. The exercise price of options granted under the 1996 Plan is
determined by the Board of Directors, but, in the case of an incentive stock
option, cannot be less than the fair market value of the common stock on the
date of grant. Options granted under the 1996 Plan vest at the rate specified in
the option agreement. Except as expressly provided by the terms of a
nonstatutory stock option agreement, no option may be transferred by the
optionee other than by will or the laws of descent or distribution or, in
limited instances, pursuant to a qualified domestic relations order, provided
that an optionee may designate a beneficiary who may exercise the option
following the optionee's death. An optionee whose relationship with Paradyne or
any of our affiliates ceases for any reason (other than due to death or
permanent and total disability) may generally exercise vested
                                       58
<PAGE>   63

options in the three month period following such cessation (unless such options
terminate or expire sooner by their terms) or in such longer or shorter period
as may be determined by the board and set forth in the option agreement. Vested
options may generally be exercised during the twelve month period after an
optionee's relationship with Paradyne or any of our affiliates ceases due to
death or disability.

     No incentive stock option may be granted to any person who, at the time of
the grant, owns (or is deemed to own) stock possessing more than 10% of the
total combined voting power of Paradyne or any of our affiliates, unless the
option exercise price is at least 110% of the fair market value of the stock
subject to the option on the date of grant and the term of the option does not
exceed five years from the date of grant. In addition, the aggregate fair market
value, determined at the time of grant, of the shares of common stock with
respect to incentive stock options granted under any plan, which become
exercisable by an optionee during any calendar year, may not exceed $100,000.
Any incentive stock options, or portions thereof, which exceed this limit are
treated as nonstatutory options.

     If we become subject to Section 162(m) of the Code, which denies a
deduction to publicly held corporations for specific compensation paid to
specific employees in a taxable year to the extent that the compensation exceeds
$1,000,000, no person may be granted options under the 1996 Plan covering more
than 2,500,000 shares of common stock in any calendar year. Shares subject to
stock awards that have lapsed or terminated, without having been exercised in
full, and any shares repurchased by Paradyne pursuant to a repurchase option
provided under the 1996 Plan may again become available for the grant of awards
under the 1996 Plan.

     Rights to acquire restricted stock granted under the 1996 Plan may be
granted subject to a repurchase option in favor of Paradyne that will expire
pursuant to a vesting schedule. The purchase price of such awards will be at
least 85% of the fair market value of the common stock on the date of grant.
Stock bonuses may be awarded in consideration for past services without the
payment of a purchase price. Rights under a stock bonus or restricted stock
bonus agreement may not be transferred other than by will, the laws of descent
and distribution or a qualified domestic relations order while the stock awarded
pursuant to such an agreement remains subject to the agreement, provided that a
holder of such rights may designate a beneficiary who may exercise the right
following the holder's death.

     Upon particular types of changes in control of Paradyne, all outstanding
stock awards under the 1996 Plan may be assumed by the surviving entity or
replaced with similar stock awards granted by the surviving entity. If the
surviving entity does not assume such awards or provide substitute awards, then
with respect to persons whose service with Paradyne or an affiliate has not
terminated prior to such change in control, the awards shall become fully vested
and will terminate if not exercised prior to such change in control.

     As of May 15, 1999, there were options to acquire 3,621,948 shares of
common stock outstanding under the 1996 Plan. The 1996 Plan will terminate in
May 2009, unless terminated sooner by the board of directors.

1999 EMPLOYEE STOCK PURCHASE PLAN

     In May 1999, our board of directors adopted and the stockholders approved
the 1999 Employee Stock Purchase Plan (the "Purchase Plan"). A total of
1,000,000 shares of common stock have been reserved for issuance under the
Purchase Plan. Each year, the number of shares reserved for issuance under the
Purchase Plan will automatically be increased by 2.0% of the total number of
shares of common stock then outstanding or, if less, by 1,000,000 shares. The
Purchase Plan is intended to qualify as an employee stock purchase plan within
the meaning of Section 423 of the Code. Under the Purchase Plan, the board of
directors or a committee comprised of at least two members of the board of
directors may authorize participation by eligible employees, including officers,
in periodic offerings following the commencement of the Purchase Plan. The
initial offering under the Purchase Plan will commence on the effective date of
this offering and terminate on April 30, 2001.

     Unless otherwise determined by the board of directors, employees are
eligible to participate in the Purchase Plan only if they are customarily
employed by us or one of our subsidiaries designated by the board of directors
for at least 20 hours per week and five months per calendar year. Employees who
participate in

                                       59
<PAGE>   64

an offering may have up to 15% of their earnings withheld pursuant to the
Purchase Plan. The amount withheld is then used to purchase shares of the common
stock on specified dates determined by the board of directors. The price of
common stock purchased under the Purchase Plan will be equal to 85% of the lower
of the fair market value of the common stock at the commencement date of each
offering period or the relevant purchase date. Employees may end their
participation in an offering at any time during such offering, and their
participation will end automatically on termination of their employment with us
or one of our subsidiaries.

     In the event of a merger, reorganization, consolidation or liquidation
involving Paradyne, the board of directors has discretion to provide that each
right to purchase common stock will be assumed or an equivalent right
substituted by the successor corporation or the board of directors may provide
for all sums collected by payroll deductions to be applied to purchase stock
immediately prior to such merger or other transaction. The board of directors
has the authority to amend or terminate the Purchase Plan, provided, however,
that no such action may adversely affect any outstanding rights to purchase
common stock.

1999 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

     In May 1999, the board of directors adopted and the stockholders approved
the 1999 Non-Employee Directors' Stock Option Plan (the "Directors' Plan") to
provide for the automatic grant of options to purchase shares of common stock to
non-employee directors of Paradyne. The Directors' Plan is administered by the
board of directors.


     The aggregate number of shares of common stock that may be issued pursuant
to options granted under the Directors' Plan is 250,000. Pursuant to the terms
of the Directors' Plan, each of our directors who is not an employee of Paradyne
(a "Non-Employee Director") will automatically be granted an option to purchase
10,000 shares of common stock upon the effective date of this offering (an
"Initial Grant"). Each person who is elected or appointed to be a Non-Employee
Director after the closing of this offering will be granted an Initial Grant
upon such election or appointment. In addition, each Non-Employee Director who
continues to serve as a Non-Employee Director of Paradyne and who attends at
least seventy-five percent (75%) of the regularly scheduled meetings of the
board and the committees of the board of which he or she is a member during the
year preceding each annual meeting of our stockholders will automatically be
granted an option to purchase 5,000 shares of common stock on the day following
each such annual meeting (an "Annual Grant"). The number of shares subject to
the Annual Grant will be reduced pro rata for each full quarter prior to the
date of the grant during which such person did not serve as a Non-Employee
Director any Non-Employee Director who has not continuously served as a director
for the entire 12-month period prior to the date of grant. Each Annual Grant
shall be fully vested on the date it is granted. Initial Grants may, at the
discretion of the board of directors, be fully vested on the day they are
granted or be vested as to 50% of the shares subject to such Initial Grants on
the date they are granted and as to the remaining 50% of the shares subject to
the Initial Grant on the first anniversary of the date they are granted. No
option granted under the Directors' Plan may have a term in excess of ten years
from the date on which it was granted. The exercise price of options under the
Directors' Plan will equal the fair market value of the common stock on the date
of grant. A Non-Employee Director whose service as a Non-Employee Director or
employee of or consultant to Paradyne or any of our affiliates ceases for any
reason other than death or permanent and total disability may generally exercise
vested options in the three-month period following such cessation (unless such
options terminate or expire sooner by their terms). Vested options may be
exercised during the 12-month period after a Non-Employee Director's service
ceases due to disability and during the 18-month period after such service
ceases due to death. The Directors' Plan will terminate in May 2009, unless
earlier terminated by the board of directors.


     As of May 15, 1999, no options to purchase common stock had been granted
pursuant to the Directors' Plan.

KEY EMPLOYEE STOCK OPTION PLAN

     The Key Employee Stock Option Plan (the "Key Employee Plan") was adopted by
our board of directors on December 29, 1997. The Key Employee Plan is
administered by the Plan Committee (the "Benefits Committee"), which committee
consists of John M. Guest, Patrick M. Murphy and H. Edward Thompson. Employees
of Paradyne holding the position of Vice President or above are eligible to
participate in the Key Employee Plan. As of May 15, 1999, fifteen employees are
eligible to participate in the plan. Participants may elect to defer up to fifty
percent (50%) of their total annual compensation in exchange for options to
purchase shares of common or preferred stock of any publicly-traded corporation,
shares of our common stock or shares in investment funds. Currently,
participants in the Key Employee Plan may only receive options to purchase
shares of investment funds administered by Fidelity Investments. The Key
Employee Plan allows the Benefits Committee, after consultation with an employee
holding an option under the Key Employee Plan, to change the shares subject to
purchase by the optionee upon exercise of such option. The options granted under
the Key Employee Plan are not intended to qualify as "incentive stock options"
under Section 422 of the Code.

     Upon the grant of an option under the Key Employee Plan, Paradyne is
required to acquire shares of the stock or investment fund subject to the option
in a number equal to 75% of the shares subject to such option. These shares will
be held by Paradyne under a trust arrangement.

     The exercise price of an option granted under the Key Employee Plan will be
equal to the greater of 25% of the fair market value of the shares subject to
the option on the date of issuance of the option or 25% of the fair market value
of the shares subject to the option on the date of exercise of the option. The
cost to the employee is the exercise price. Options granted under the Key
Employee Plan are fully vested upon grant and may be exercised at any time after
the date that is six months after the date they are granted. The term of an
option granted under the Key Employee Plan may not exceed ten years. An optionee
whose service with Paradyne terminates may exercise options granted under the
Key Employee Plan within twelve months following such termination.

     Unless the terms of an option granted under the Key Employee Plan provide
otherwise, such options may be transferred to an optionee's spouse or lineal
descendants or the trustee of a trust established for the optionee's spouse or
lineal descendants.

     As of May 15, 1999, Andrew May, Patrick Murphy, Sean Belanger, Paul Floyd
and John Guest were the only participants in the Key Employee Plan.

401(K) PLAN

     We have established the Paradyne Corporation Retirement Savings Plan
effective August 1, 1996 (the "401(k) Plan"). The 401(k) Plan is intended to
qualify under Section 401 of the Code so that contributions by employees or by
Paradyne, and income earned thereon, are not taxable until withdrawn and so that
contributions by Paradyne will be deductible by Paradyne when made. The 401(k)
Plan provides that each participant may reduce his or her pre-tax gross
compensation by up to 16% (up to a statutorily prescribed annual limit of
$10,000 in 1999) and have that amount contributed to the 401(k) Plan. Employees
become eligible to participate in the 401(k) Plan upon commencement of their
employment with Paradyne. Participants are fully vested in all amounts they
contribute under the 401(k) Plan and in the earnings on such amounts.

     In addition to the employee salary deferrals described above, the 401(k)
Plan requires Paradyne to make contributions under the 401(k) Plan on behalf of
the participants. These contributions include a matching contribution of 66 2/3%
of the first 6% of salary deferral contributions made by each participant. The
401(k) Plan also permits Paradyne to make an employer contribution in an amount
to be determined by the board of directors or, if no such amount is determined,
in an amount of between 1% and 4.5% of the annual compensation of each
participant. The amount of such employer contributions to be received by each
participant will be determined based on the age of the participant. Participants
become vested in matching

                                       61
<PAGE>   66

contributions and employer contributions according to a graded vesting schedule
under which they become fully vested after four years of service with Paradyne.

     Employee participants may elect to invest their accounts under the 401(k)
Plan in various established funds.

LIMITATIONS ON DIRECTORS' AND EXECUTIVE OFFICERS' LIABILITY AND INDEMNIFICATION

     Our bylaws provide that Paradyne shall indemnify its directors and
executive officers to the fullest extent permitted by Delaware law, except with
respect to some specific proceedings initiated by such persons. Paradyne is also
empowered under its bylaws to enter into indemnification contracts with its
directors and executive officers and to purchase insurance on behalf of any
person it is required or permitted to indemnify.

     In addition, our restated certificate provides that a director of Paradyne
will not be personally liable to Paradyne or its stockholders for monetary
damages for any breach of fiduciary duty as a director, except for:

     - any breach of the director's duty of loyalty to Paradyne or its
       stockholders;

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

     - unlawful payments of dividends or unlawful stock repurchases or
       redemptions; and

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

     The restated certificate also provides that if the Delaware General
Corporation Law is amended after the approval by our stockholders of the
restated certificate to authorize corporate action further eliminating or
limiting the personal liability of directors, then the liability of Paradyne's
directors shall be eliminated or limited to the fullest extent permitted by the
Delaware General Corporation Law, as so amended. The provision does not affect a
director's responsibilities under any other law, such as the federal securities
laws or state or federal environmental laws.

     We entered into an indemnification agreement with William Stensrud, one of
our directors, on November 6, 1996. Under the agreement, we agreed to reimburse
and indemnify Mr. Stensrud for civil or criminal proceedings or governmental
investigations relating to Mr. Stensrud's actions as a director, except if such
conduct was committed in bad faith or was a breach of Mr. Stensrud's duty of
loyalty to us.

                              CERTAIN TRANSACTIONS

     The following is a description of transactions since January 1, 1996, to
which Paradyne has been a party, in which the amount involved in the transaction
exceeds $60,000, and in which any of our directors, executive officers or
holders of more than 5% of the capital stock had or will have a direct or
indirect material interest other than compensation arrangements which are
otherwise required to be described under "Management."

DIVESTITURE BY LUCENT

  Initial Formation

     Prior to the divestiture, the predecessor business operated several
businesses, which were either acquired by Communication Partners, L.P. or
retained by Lucent. Shares of common stock of the predecessor business were
traded on the New York Stock Exchange from 1978 to 1989 at which point the
predecessor business was acquired by AT&T. Communication Partners, L.P. was
originally formed under the name Paradyne Partners, L.P. in connection with the
divestiture for the primary purpose of holding investments in Paradyne and
GlobeSpan. In the divestiture, Communication Partners, L.P. formed:

     - Lease Acquisition Corp., as a subsidiary

     - Paradyne Credit Corp. which was formerly called Rental Acquisition Corp.,
       as a subsidiary

     - GlobeSpan, Inc., which was formerly called CAP Acquisition Group, as a
       subsidiary

     - Paradyne Acquisition Corp., as a wholly-owned subsidiary to hold the
       common stock of Paradyne Corporation and Lease Acquisition Corp.

Acquisition Corp. In connection with these acquisitions, the predecessor
business assigned appropriate assets and resources to the subsidiaries. Lease
Acquisition Corp. sold its assets to Paradyne Credit Corp. and was subsequently
merged with and into Paradyne Networks. See "-- Subsequent
Transactions -- Transactions with Paradyne Credit Corporation."

     Interim Promissory Note.  In connection with the divestiture, we issued an
interim promissory note payable to Lucent in the amount of $7.5 million. This
note matured on December 31, 1997 and carried an interest rate of 8.5% per annum
for the period July 31, 1996 through December 31, 1996 and 11.5% per annum
thereafter. This note was secured by the land and buildings in Largo, Florida
owned by us at the time of the divestiture. On June 27, 1997, the land and
buildings in Largo, Florida were sold, and this indebtedness was repaid. We
recognized interest expense of approximately $267,000 and $421,000 for the five
months ended October 31, 1996 and the year ended December 31, 1997,
respectively.

     Promissory Note.  In connection with the divestiture, we issued a
promissory note payable to Lucent in the amount of $61.8 million. This note
carried an interest rate of 8.5% per annum for the period July 31, 1996 through
December 31, 1997, 11.5% per annum for the period January 1, 1998 through
December 31, 1998 and 14.5% per annum thereafter. Under the terms of this note,
interest payments totalling $7.6 million were deferred for the period August 1,
1996 through December 31, 1997. Interest was payable quarterly subsequent to
December 31, 1997. The principal balance, along with any deferred interest, was
due and payable on June 30, 2000. Additionally, the terms of this note called
for a mandatory prepayment of principal and related interest under certain
circumstances. One such circumstance was the sale of the land and buildings in
Largo, Florida, and as such, we paid Lucent $3.7 million in principal and
deferred interest in

                                       64
<PAGE>   69

June 1997. Of the remainder of the principal and deferred interest, $63.0
million was forgiven in 1997 and $2.7 million was paid in 1998 in connection
with a settlement with Lucent as described under "Subsequent
Transactions -- Transactions with Lucent -- Lucent Settlement" below.

     TRANSACTIONS WITH LUCENT

     Intellectual Property Agreement.  As part of the divestiture, we entered
into an intellectual property agreement with Lucent and GlobeSpan. Under this
agreement, Lucent irrevocably assigned to us and our successors all rights in
particular patents related to our proprietary technology. In exchange, we
granted to Lucent a non-exclusive license to develop, manufacture, test or
repair products using the assigned patents.

     Non-Competition Agreement.  As part of the divestiture, Lucent entered into
a non-competition agreement with GlobeSpan and us. Under this agreement, Lucent
agreed not to compete with us (with a separate agreement not to compete with
GlobeSpan) with respect to the manufacture and sale of products, which either
compete with the principal products of Paradyne or compete with technologies
under development by Paradyne at the time of the divestiture. The cross-license
and non-competition agreements do not prevent GlobeSpan and AT&T from competing
with Paradyne.

     AT&T Trademark and Patent Agreement.  As part of the divestiture, AT&T
(Lucent's principal stockholder at the time) entered into a trademark and patent
agreement with us and GlobeSpan. Under this agreement, AT&T granted us a
non-exclusive, non-transferable, irrevocable, worldwide, royalty-free license
under particular listed AT&T patents to develop, manufacture, test or repair our
products existing at the time of the divestiture.

     Supply Agreement.  As part of the divestiture, we entered into a supply
agreement with Lucent and GlobeSpan. Under the terms of this agreement, we
agreed to sell a variety of listed products to Lucent at prices at least as low
as those prices offered to other customers and Lucent agreed to purchase minimum
amounts of products from Paradyne. We also entered into a volume purchase letter
agreement, whereby Lucent agreed to purchase minimum levels of products from us
for a period of four years. The volume purchase letter agreement was
subsequently terminated with an effective date in 1997 in connection with a
settlement with Lucent. In 1997, we amended the supply agreement in connection
with a settlement with Lucent and became the exclusive supplier to Lucent of
Lucent's requirements for network access products for resale through June 2001,
provided that these products possess satisfactory design, function, and
performance characteristics. See "Subsequent Transactions -- Transactions with
Lucent -- Lucent Settlement" below.

     TRANSACTIONS WITH GLOBESPAN

     Cross-License.  As part of the divestiture, we entered into a cross-license
agreement with GlobeSpan. Under this agreement, each party granted to the other
party a non-exclusive, non-transferable, irrevocable, world-wide, royalty-free
license to the patents Lucent assigned to the granting party in the divestiture,
for use in the other party's products that existed as of the date of the
divestiture, and subsequent modifications to those products. Each party also
granted to the other party a non-exclusive, non-transferable, irrevocable,
world-wide, royalty-free license to the granting party's other technical
information and intellectual property existing at the time of the divestiture.
These licenses give us the right to make, have made, use, sell and import our
products within the scope of the license grants as well as the tools used to
develop, manufacture, test or repair such products. We were also given the right
to convey to any of our customers the right to use and resell such products.
Each party also granted to the other party a non-exclusive, non-transferable,
irrevocable, world wide, royalty-free license to use particular listed
trademarks. All of these licenses have an indefinite duration, subject to the
expiration of patent and copyright terms.

     Royalty Payments to GlobeSpan.  In conjunction with the license to
reproduce GlobeSpan software, we paid GlobeSpan a total of $235,000 in royalty
payments in 1996. This payment reflected the cost of a chip set reference design
guide and a right-to-use fee. The rates were determined in accordance with a
September 1995 license agreement. Effective July 1998, the Company revised its
pricing arrangement with GlobeSpan such that GlobeSpan sold products to the
Company at preferential prices. In exchange, GlobeSpan agreed to pay a 1.25%
royalty based on net revenues up to an aggregate amount of $1.5 million. The
Company recorded $381,000 of royalty revenue related to the agreement during the
year ended December 31, 1998.
                                       65
<PAGE>   70

     Services Agreement.  As part of the divestiture, we entered into an
intercompany services agreement under which we agreed, for a period of time, to
provide GlobeSpan with the following services due to their limited
infrastructure.

     - human resources, staffing and legal services;

     - administrative services, including risk management, patent management,
       tax management and accounting support; and

     - operational services, including office communications and
       telecommunications systems management, facilities management, rent and
       other services.

     GlobeSpan now provides all of the above-mentioned services directly, except
for insurance and 401(k) administration, which we still provide. This agreement
can be terminated by GlobeSpan on 60 days notice and by us on 180 days notice.
GlobeSpan paid us a total of $155,000 and $231,000 for the years ended December
31, 1997 and 1998 under the services agreement. In 1998, we subleased additional
office space to GlobeSpan. In connection with the relocation of our offices,
GlobeSpan reimbursed us approximately $392,000 of our moving expenses.

     Various Insurance Policies.  The directors and officers of Communication
Partners, Communication GenPar, Inc., Paradyne, Paradyne Acquisition Corp.,
Paradyne Credit Corp. and GlobeSpan are covered under one umbrella insurance
policy providing up to $10.0 million of liability coverage. Additionally,
Paradyne, Paradyne Credit Corp. and GlobeSpan are jointly covered under various
general liability, property, casualty and workers' compensation policies. The
term of these policies is from August 31, 1998 to August 31, 1999. We jointly
entered into these policies to obtain the cost benefit of common control entity
premiums. We expect that we will not share insurance policies with GlobeSpan
after this offering. We expect to have our own directors and officers' insurance
policy in effect prior to the closing of this offering.

     401(k) Plan.  We maintain a 401(k) plan, which substantially all of
GlobeSpan's employees currently participate in due to the administrative
economic benefits of a single employer plan. Effective May 1, 1999, GlobeSpan
expects to adopt its own 401(k) plan for its employees. Contributions for the
five months ended December 31, 1996 and for the years 1997 and 1998, including
discretionary matches, paid by Paradyne on behalf of GlobeSpan amounted to
approximately $65,000, $321,000 and $379,000. All payments made on behalf of
GlobeSpan have been or will be reimbursed.

     TRANSACTIONS WITH LEASE ACQUISITION CORP.

     Services Agreement.  As part of the divestiture, we entered into an
intercompany services agreement with Lease Acquisition Corp. under which we
agreed to provide:

     - general management consulting and services administration, including
       lease contract servicing and remarketing services;

     - administrative services, including risk management, financial and cash
       management, tax management and accounting services;

     - human resources, staffing and legal services; and

     - operational services, including facilities management, office
       communications, telecommunication systems, systems management and other
       services.

     In exchange for these services, Lease Acquisition Corp. agreed to pay us a
monthly service fee of $5,000 per month. This agreement was terminated by mutual
consent in August 1997. Payments received for these services were $25,000 for
the five months ended December 31, 1996 and $35,000 for the period January 1,
1997 through August 1, 1997.

     TRANSACTIONS WITH PARADYNE CREDIT CORP.

     Services Agreement.  As part of the divestiture, we entered into an
intercompany services agreement with Paradyne Credit Corp. under which we agreed
to provide:

     - general management consulting and services administration, including
       rental contract servicing administration and remarketing services;

     - administrative services, including risk management, financial and cash
       management, tax management and accounting services;

     - human resources, staffing and legal services; and

     - operational services, including facilities management, office
       communications, telecommunication systems, systems management and other
       services.

     In exchange for these services, Paradyne Credit Corp. agreed to pay us a
monthly service fee equal to 5% of their net revenue. This agreement may be
terminated by Paradyne Credit Corp. upon 60 days notice and by us upon 180 days
notice. Payments received for these services were $407,000 and $521,000 for the
five months ending December 31, 1996 and the seven month period ending July 31,
1997, respectively. See "Subsequent Transactions -- Transactions with Paradyne
Credit Corp." below.

     In addition, Paradyne Credit Corp. received an option to purchase our used
equipment that had been returned from expired or terminated leases, sales to
customers or consignment activities. Payments received for the purchase of the
equipment totaled $115,000 and $81,000 for the five months ended December 31,
1996 and the year ended December 31, 1997. This option terminated in August 1997
as described under "Subsequent Transactions -- Transactions with Paradyne Credit
Corp. -- Sale of Lease Receivables and Related Equipment" below.

     TRANSACTIONS WITH COMMUNICATION PARTNERS

     Interim Promissory Note.  In connection with the divestiture, we issued a
promissory note payable to Communication Partners in the amount of $7.5 million.
This note matured on December 31, 1997 and carried an interest rate of 8.5% per
annum for the period July 31, 1996 through December 31, 1996 and 11.5% per annum
thereafter. This note was secured by the land and buildings in Largo, Florida
owned by us at the time of the divestiture. On June 27, 1997, the land and
buildings in Largo, Florida were sold, and this indebtedness was repaid. We
recognized interest expense of approximately $267,000 and $421,000 for the five
months ended December 31, 1996 and the year ended December 31, 1997,
respectively.

SUBSEQUENT TRANSACTIONS

     TRANSACTIONS WITH LUCENT

     Lucent Settlement.  As at December 31, 1997, Lucent had not satisfied its
obligations under the volume purchase letter agreement and, therefore, was
subject to take or pay provisions. We entered into a settlement with Lucent,
effective in 1997 whereby we agreed to terminate the volume purchase letter
agreement, amended our supply agreement with Lucent to become the exclusive
supplier to Lucent of Lucent's requirements for network access products for
resale through June 2001 and received $8.2 million of cash and the cancellation
of the promissory note to Lucent in the amount of $63.0 million. In addition,
GlobeSpan amended a warrant that it originally granted to Lucent at the time of
the 1996 acquisition. The amendment extended the warrant terms by three years.
Because both GlobeSpan and Paradyne are subsidiaries of Communication Partners,
we recognized a contribution of capital by Communication Partners of $3.6
million, reflecting the estimated fair market value of the extension of the
GlobeSpan warrant.

     TRANSACTIONS WITH GLOBESPAN

     Reimbursement for Chip Set Purchases.  Due to GlobeSpan's limited
infrastructure at the beginning of its existence in 1996, GlobeSpan purchased
chip sets from Lucent through us for sale to GlobeSpan

                                       67
<PAGE>   72

customers. We paid Lucent for these chip sets on GlobeSpan's behalf, and
GlobeSpan reimbursed us for their cost. These reimbursements totaled $194,000.

     Cooperative Development Agreement/Termination Agreement/Supply
Agreement.  In November 1996, we entered into a cooperative development
agreement and a related rider agreement with GlobeSpan. Under the terms of these
agreements and in consideration for a contribution of $6.0 million by
Communication Partners to GlobeSpan, we were provided with a broad,
royalty-free, unrestricted license to use GlobeSpan's technical information and
patents for any purpose related to our products. We were also granted the right
to acquire GlobeSpan's chip sets at prices not to exceed cost plus 15%. The term
of the cooperative development agreement was 5 years. The term of rider
agreement was 10 years and we had the right to extend it for an additional
10-year term. In addition, we leased assets and equipment to GlobeSpan for an
annual lease fee of $1.00. Effective December 1998, GlobeSpan and we terminated
these agreements pursuant to a termination agreement. The termination agreement
provided that GlobeSpan agreed, effective July 1998, to pay us a total of $1.5
million in royalties. GlobeSpan and we agreed that approximately $400,000 of
these royalties had been paid as of the effective date of the termination
agreement and that GlobeSpan would pay to us the approximately $1.1 million
balance of royalties the sooner of December 31, 1999 or within 30 days of the
effective date of GlobeSpan's initial public offering.

     In conjunction with the signing of the termination agreement, we entered
into a four-year supply agreement with GlobeSpan, which gives us preferential
pricing and other terms in connection with the purchase of GlobeSpan products.
Under the terms of this agreement, GlobeSpan is required to honor our orders for
GlobeSpan products in quantities at least consistent with our past ordering
practices and must afford us at least the same priority for its orders as
GlobeSpan affords other similarly situated highly preferred customers. We were
also granted immunity under GlobeSpan's intellectual property rights for all our
customers that purchase our products that incorporate GlobeSpan products.
GlobeSpan has been selling products to us pursuant to these terms since July
1998. In 1997 and 1998, we paid to GlobeSpan a total of $373,000 and $962,000,
respectively, for products purchased under the cooperative development
agreement, the related rider agreement and the termination agreement.

     Inventory Repurchases by GlobeSpan.  In December 1997 and September 1998,
GlobeSpan repurchased some of its chip sets for their own inventory needs, which
we held in more than adequate supply in our inventory in the amounts of $98,000
and $29,000, respectively.

     Purchase of Fixed Assets.  In 1997 and in 1998, GlobeSpan purchased fixed
assets in a non-arm's-length transaction for approximately $350,000 and
$400,000, respectively, which were owned by us but which they used in their
business. Prior to the sale of the equipment to GlobeSpan, the related
depreciation expense of $106,000 in 1996 and $244,000 in 1997 was transferred to
GlobeSpan for its use, which was reflected as a distribution of equity to a
related party in the statement of changes in stockholder equity. In 1998,
GlobeSpan purchased fixed assets from us related to a subleased facility that
they needed for their operations for $1.0 million, which included costs to
remodel offices previously used by us.

     Real Property Agreements.  Under a sublease dated August 1997, and
subsequently amended in August 1998, between GlobeSpan and us, GlobeSpan
subleases property at 100 Schulz Drive, Red Bank, New Jersey. The sublease
reimburses us for 100% of all costs we incur under the primary lease. GlobeSpan
currently pays us approximately $68,000 a month for approximately 50,000
rentable square feet, plus approximately $10,000 per month for rent operating
costs. After October 2001, the rent will increase to approximately $79,000 a
month for a period of six months. The sublease expires in April 2002.

     TRANSACTIONS WITH LEASE ACQUISITION CORP.

     Merger of Lease Acquisition Corp. into Paradyne Acquisition Corp.  In
August 1997, Lease Acquisition Corp. sold its net assets to Paradyne Credit
Corp. in exchange for a promissory note totalling approximately $4.8 million and
merged with and into Paradyne Acquisition Corp. As a result of this merger,
Paradyne Acquisition Corp. acquired Paradyne Credit Corp.'s promissory note.

                                       68
<PAGE>   73

     TRANSACTIONS WITH PARADYNE CREDIT CORP.

     Purchase of Installment and Accounts Receivables.  In December 1996, we
purchased installment and accounts receivables relating to long-term equipment
leases in the aggregate amount of $14.0 million from Paradyne Credit Corp. in
exchange for a promissory note of $13.7 million. A deferred gain of $291,000 was
included in other current liabilities at December 1996. The promissory note bore
an interest rate of 9.25% and was scheduled to mature in December 1997. In
January 1997, we sold the receivables back to Paradyne Credit Corp. in exchange
for cancellation of the promissory note. We recognized interest expense of
approximately $10,000 in connection with the transaction.

     Sale of Lease Receivables and Related Equipment.  In August 1997, we sold
all equipment under lease, as well as the related future lease payments, to
Paradyne Credit Corp., our equipment leasing affiliate, for approximately $3.5
million, the approximate book value of the equipment and related future lease
payments. We, however, are allowed to purchase from Paradyne Credit Corp.
equipment that has been returned to Paradyne Credit Corp. after the termination
of the lease. These purchases are on terms no more favorable to us than would be
obtained in a comparable arm's length transaction and totaled $0 and $141,000
for the year ended December 31, 1997 and 1998, respectively. Paradyne Credit
Corp. may purchase equipment manufactured or sold by us at prices substantially
equal to those received by us through normal selling channels. Payments received
from the sales of such equipment totaled $181,000 and $317,000 for the year
ended December 31, 1997 and 1998, respectively.

     In connection with this sale, the Paradyne Credit Corp. services agreement
was amended to change the monthly service fee to equal the sum of: (i) all
direct costs incurred by us to provide services to Paradyne Credit Corp. and
(ii) up to five percent (5%) of the net revenues of Paradyne Credit Corp. for
any indirect costs. Payments received for these services were $344,000 and
approximately $1.2 million for the five months ended December 31, 1997 and for
the year ended December 31, 1998, respectively.

     In April 1999, this agreement was again modified to adjust the monthly
service fee to equal to the sum of: (i) all direct costs incurred by us to
provide services to Paradyne Credit Corp., (ii) all indirect costs incurred by
us to provide services to Paradyne Credit Corp. and (iii) a 5% mark up on all
charges.

     In connection with a sale of lease receivables to AT&T Capital Corp., we
guaranteed collection of selected receivables to AT&T Capital Corp. As of
December 31, 1998, lease receivables for which we were contingently liable, but
for which we have recourse, were outstanding in the amount of $886,000. The
ultimate responsibility for the collection of these receivables is with Paradyne
Credit Corp.

     TRANSACTIONS WITH COMMUNICATION PARTNERS

     Subordinated Revolving Promissory Note.  In August 1997, Communication
Partners agreed to provide to us a revolving line of credit facility in the
maximum amount of $5.0 million. This agreement was amended in October 1998 to
increase the maximum principal amount of the facility to $10.0 million. Interest
paid under this note totaled $0 and $305,000 for the year ended December 31,
1997 and 1998, respectively. As of March 31, 1999, there is no outstanding
balance on the credit facility. Borrowings under this agreement are subordinated
to debt under our Bank of America NT&SA revolving credit facility.

     Continuing Limited Guaranty.  In October 1998, Communication Partners
entered into a continuing guaranty for the benefit of Bank of America NT&SA in
connection with our revolving credit facility. The maximum liability under this
guaranty was $10.0 million, reduced by any principal amount outstanding under
the subordinated revolving promissory note discussed above. This guaranty was
canceled in March 1999.

PROMISSORY NOTES FROM OFFICERS

     On May 5, 1997, James L. Slattery, Senior Vice President, Chief Legal and
Intellectual Property Officer and Corporate Secretary, issued to us a promissory
note in the amount of $149,850 in connection with his purchase of 75,000 shares
of our common stock. The full recourse note accrues interest at a rate of 6.65%
per annum. The principal balance of this note and accrued interest are payable
at the earlier of termination of employment or five years from the date of the
note. The note is secured by the shares of common stock

                                       69
<PAGE>   74

acquired with the note, which shares are held in escrow by us. As of May 15,
1999, the balance outstanding was $149,850, plus accrued interest.

                       PRINCIPAL AND SELLING STOCKHOLDERS

     This table sets forth certain information regarding the beneficial
ownership of our outstanding common stock as of May 15, 1999, by the following:

     - each person known by us to own beneficially more than five percent of the
       outstanding common stock;

     - each director of Paradyne;

     - each Named Executive Officer;

     - each stockholder of Paradyne who is selling shares of common stock in
       this offering; and

     - all directors and executive officers of Paradyne as a group.

     The following calculations of the percentage of outstanding shares are
based on 26,312,508 shares of our common stock outstanding as of May 15, 1999
and 30,312,508 shares outstanding immediately following the completion of this
offering and assumes no exercise of the underwriters' over-allotment option,
under which the underwriters have an option to purchase an additional 900,000
shares from the selling stockholders. Beneficial ownership is determined in
accordance with the rules of the Securities and Exchange Commission and
generally includes voting or investment power with respect to securities,
subject to community property laws, where applicable. Shares of our common stock
subject to options that are presently exercisable or exercisable within 60 days
of May 15, 1999 are deemed to be outstanding and beneficially owned by the
person holding such options for the purpose of computing the percentage of
ownership of such person but are not treated as outstanding for the purpose of
computing the percentage of any other person.

     The numbers shown in the table below assume no exercise by the underwriters
of their over-allotment option.

                          DESCRIPTION OF CAPITAL STOCK

     The authorized capital stock of Paradyne Networks consists of 60,000,000
shares of common stock, $.001 par value and 5,000,000 shares of preferred stock
$.001 par value. There were 26,312,508 shares of Paradyne common stock
outstanding as of May 15, 1999, held of record by 133 stockholders, and there
are no outstanding shares of preferred stock.

COMMON STOCK

     The holders of common stock of Paradyne Networks are entitled to one vote
per share on all matters to be voted on by the stockholders. Subject to
preferences that may be applicable to any outstanding shares of preferred stock,
holders of common stock are entitled to receive ratably such dividends as may be
declared by the board of directors out of funds legally available therefor. In
the event we liquidate, dissolve or wind up, holders of common stock are
entitled to share ratably in all assets remaining after payment of liabilities
and the liquidation preferences of any outstanding shares of preferred stock.
Holders of common stock have no preemptive, conversion, or subscription rights.
There are no redemption or sinking fund provisions applicable to the common
stock. All outstanding shares of common stock are, and all shares of common
stock to be outstanding upon completion of this offering will be, fully paid and
nonassessable.

PREFERRED STOCK

     Under the amended and restated certificate of Paradyne Networks, the board
has the authority, without further action by stockholders, to issue up to
5,000,000 shares of preferred stock in one or more series and to fix the rights,
preferences, privileges, qualifications and restrictions granted to or imposed
upon such preferred stock, including dividend rights, conversion rights, voting
rights, rights and terms of redemption, liquidation preference and sinking fund
terms, any or all of which may be greater than the rights of the common stock.
The issuance of preferred stock could adversely affect the voting power of
holders of common stock and reduce the likelihood that such holders will receive
dividend payments and payments upon liquidation. Such issuance could have the
effect of decreasing the market price of the common stock. The issuance of
preferred stock could also have the effect of delaying, deterring or preventing
a change in control of Paradyne. We have no present plans to issue any shares of
preferred stock.

WARRANTS

     There are no outstanding warrants for the purchase or acquisition of stock
of Paradyne.

REGISTRATION RIGHTS

     Paradyne intends to enter into an agreement that grants registration rights
related to the stock of Paradyne held by entities affiliated with Texas Pacific
Group. Under the terms of this proposed agreement, if we propose to register
shares not held by the affiliates of Texas Pacific Group, these affiliates would
be entitled to notice of such registration and would be allowed to include their
shares in such registration, subject to various conditions and limitations which
have yet to be finalized. In addition, we might be required to prepare and file
a registration statement under the Securities Act of 1933 if requested to do so
by entities affiliated with Texas Pacific Group owning at least 5% of our
outstanding common stock. We would be required to use our best efforts to effect
such registration, subject to various conditions and limitations which have yet
to be finalized. We would be required to bear substantially all costs in
connection with any such registrations.

DELAWARE ANTI-TAKEOVER LAW

     Paradyne is subject to the provisions of Section 203 of the Delaware
General Corporation Law. In general, Section 203 prohibits a publicly held
Delaware corporation from engaging in a "business combination" with an
"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 is approved in a prescribed manner. A "business
combination" includes mergers, asset sale or other transactions resulting in a
                                       74
<PAGE>   79

financial benefit to the stockholder. An "interested stockholder" is a person
who, together with affiliates and associates, owns (or within three years, did
own) 15% or more of the corporation's voting stock. The statute could have the
effect of delaying, deferring or preventing a change in control of Paradyne.

     Our amended and restated certificate provides that any action required or
permitted to be taken by our stockholders must be effected at a duly called
annual or special meeting of stockholders and may not be effected by any consent
in writing. In addition, our amended and restated bylaws provide that special
meetings of our stockholders may be called only by the Chairman of the board of
directors, the Chief Executive Officer or the board of directors pursuant to a
resolution adopted by a majority of the total number of authorized directors, or
by the holders of 50% of the outstanding voting stock of Paradyne. Our amended
and restated certificate also specifies that our board of directors will be
classified into three classes of directors. Under Delaware law, directors of a
corporation with a classified board may be removed only for cause unless the
corporation's certificate of incorporation provides otherwise. The amended and
restated certificate does not provide otherwise. In addition, the amended and
restated certificate specifies that the authorized number of directors may be
changed only by resolution of the board of directors and does not include a
provision for cumulative voting for directors. Under cumulative voting, a
minority stockholder holding a sufficient percentage of a class of shares may be
able to ensure the election of one or more directors. Our amended and restated
certificate may only be amended with the approval of 66 2/3% of our outstanding
voting stock and our amended and restated bylaws may be amended either by the
board or by the approval of 66 2/3% of our outstanding voting stock.
Furthermore, our amended and restated certificate requires the advance notice of
stockholders' nominations for the election of directors and business brought
before a meeting of stockholders. Lastly, the amended and restated certificate
provides that a majority of the directors in office, even if less than a quorum,
are entitled to fill vacancies created by resignation, death, disqualification,
removal or by an increase in the size of the board. These provisions contained
in the amended and restated certificate and our amended and restated bylaws
could delay or discourage certain types of transactions involving an actual or
potential change in control of Paradyne or its management, which includes
transactions in which stockholders might otherwise receive a premium for their
shares over then current prices, and may limit the ability of stockholders to
remove our current management or approve transactions that stockholders may deem
to be in their best interests and, therefore, could adversely affect the price
of our common stock.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is Norwest Bank
Minnesota, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Immediately prior to this offering, there was no public market for our
common stock. Future sales of substantial amounts of common stock in the public
market could adversely affect the market price of the common stock.

     Upon completion of this offering, we will have outstanding 30,312,508
shares of common stock, assuming the issuance by Paradyne of 4,000,000 shares of
common stock offered hereby and no exercise of options after May 15, 1999. Of
these shares, the 6,000,000 shares sold in this offering will be freely tradable
without restriction or further registration under the Securities Act, unless
such shares are purchased by "affiliates" as that term is defined in Rule 144
under the Securities Act (whose sales would be subject to certain limitations
and restrictions described below).

     The remaining 24,312,508 shares of common stock held by existing
stockholders as of May 15, 1999 will be "restricted securities" as that term is
defined in Rule 144 (the "Restricted Securities"). Shares totalling 24,230,906
will be subject to "lock-up" agreements described below on the effective date of
this offering. Upon expiration of the lock-up agreements 180 days after the
effective date of this offering, all of these shares will become eligible for
sale, subject in most cases to the limitations of Rule 144 and Rule 701.
Restricted Securities held by non-affiliates will be eligible for sale pursuant
to Rule 144(k), as described below. In addition, holders of stock options could
exercise such options and sell certain of the shares issued upon exercise as
described below.

     As of May 15, 1999, there were a total of 3,621,948 shares of common stock
subject to outstanding options under our 1996 Equity Incentive Plan, 1,606,973

the shares of common stock issued or reserved for future issuance under our 1996
Equity Incentive Plan. On the date 180 days after the effective date of this
offering, at least 2,157,445 shares of common stock will be subject to
immediately exercisable options. After the effective date of the registration
statement on Form S-8, shares purchased upon exercise of options granted
pursuant to the 1996 Equity Incentive Plan generally would be available for
resale in the public market.

     Our officers, directors and certain stockholders have agreed not to sell or

RULE 144

     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year, including any affiliates of ours, 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, which
          will equal approximately 303,125 shares immediately after this
          offering; or

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

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

RULE 144(K)

     Under Rule 144(k), a person who is not deemed to have been one of
Paradyne's "affiliates," as defined in Rule 144, 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, including the holding period of any prior owner other
than an "affiliate," is entitled to sell such shares without complying with the

restricted, "144(k) shares" may be sold immediately upon the completion of this
offering.

RULE 701

     In general, under Rule 701, any Paradyne employee, director, officer,
consultant or advisor who purchases shares from Paradyne in connection with a
compensatory stock or option plan or other written agreement before the
effective date of the offering is entitled to resell such shares 90 days after
the effective date of this offering in reliance on Rule 144, without having to
comply with certain restrictions, including the holding period, contained in
Rule 144.

     The SEC has indicated that Rule 701 will apply to stock options granted by
an issuer before it becomes subject to the reporting requirements of the
Securities Exchange Act of 1934, along with the shares acquired upon exercise of
such options, including exercises after the date of this prospectus. Securities
issued in reliance on Rule 701 are restricted securities and, subject to the
contractual restrictions described above, beginning 90 days after the date of
this prospectus, may be sold by persons other than "affiliates," as defined in
Rule 144, subject only to the manner of sale provisions of Rule 144 and by
"affiliates" under Rule 144 without compliance with its one-year minimum holding
period requirement.

     The selling stockholders have granted to the underwriters an option,
exercisable within 30 days after the date of this prospectus, to purchase, from
time to time, in whole or in part, up to an aggregate of 900,000 additional
shares of common stock at the initial public offering price less underwriting
discounts and commissions. The underwriters may exercise such option solely to
cover overallotments, if any, made in connection with the offering. To the
extent that the underwriters exercise such option, each underwriter will become
obligated, subject to certain conditions, to purchase its pro rata portion of
such additional shares based on such underwriter's initial purchase commitment.

     Paradyne and the selling stockholders have agreed to indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended, or to contribute to payments that the
underwriters may be required to make in respect thereof.

     Each of Paradyne, its executive officers and directors and certain
stockholders and optionholders of Paradyne, including the selling stockholders,
have agreed, subject to certain exceptions, not to

     - offer, pledge, sell, contract to sell, sell any option or contract to
       purchase, purchase any option or contract to sell, grant any option,
       right or warrant to purchase or otherwise transfer or dispose of,
       directly or indirectly, any shares of common stock or any securities
       convertible into or exercisable or exchangeable for common stock, or

     - enter into any swap or other arrangement that transfers all or a portion
       of the economic consequences associated with the ownership of any common
       stock

for a period of 180 days after the date of this prospectus without the prior
written consent of Donaldson, Lufkin & Jenrette Securities Corporation. During
such 180-day period, Paradyne may issue shares of common stock in connection
with acquisitions of other businesses, products or technologies, so long as the
recipients of common stock in such acquisitions agree in writing to be bound by
the same restrictions applicable to Paradyne and the selling stockholders. In
addition, during such 180-day period, Paradyne has also agreed not to file any
registration statement with respect to, and each of its executive officers,
directors and certain stockholders of Paradyne, including the selling
stockholders, has agreed not to make any demand for, or exercise any right with
respect to, the registration of any shares of common stock or any securities
convertible into or exercisable or exchangeable for common stock without the
prior written consent of Donaldson, Lufkin & Jenrette Securities Corporation.

     At the request of Paradyne, the underwriters have reserved up to five
percent of the shares of common stock to be issued by Paradyne and offered
hereby for sale, at the initial public offering price, to directors, officers,
employees, some stockholders and their employees and affiliates, consultants,
customers, distributors and other persons. The number of shares of common stock
available for sale to the general public will be reduced to the extent such
individuals purchase such reserved shares. Any reserved shares which are not so
purchased will be offered by the underwriters to the general public on the same
basis as the other shares offered hereby.

     Prior to the offering, there has been no established trading market for
Paradyne's common stock. The initial public offering price for the shares of
Paradyne's common stock offered hereby will be determined by negotiation among
Paradyne, representatives of the selling stockholders and the representatives of
the underwriters. The factors to be considered in determining the initial public
offering price include the history of and the prospects for the industry in
which Paradyne competes, the past and present operations of Paradyne, the
historical results of operations of Paradyne, the prospects for future earnings
of Paradyne, the recent market prices of securities of generally comparable
companies and the general condition of the securities markets at the time of the
offering.

     Application has been made to have the common stock approved for quotation
on the Nasdaq National Market under the symbol "PDYN."

     Other than in the United States and as described below with respect to the
United Kingdom, no action has been taken by Paradyne, the selling stockholders,
or the underwriters that would permit a public offering of the shares of common
stock offered hereby in any jurisdiction where action for that purpose is
required.

The shares of common stock offered hereby may not be offered or sold, directly
or indirectly, nor may this prospectus or any other offering material or
advertisements in connection with the offer and sale of any such shares of
common stock be distributed or published in any jurisdiction, except under
circumstances that will result in compliance with the applicable rules and
regulations of such jurisdiction. Persons into whose possession this prospectus
comes are advised to inform themselves about and observe any restrictions
relating to the offering and the distribution of this prospectus. This
prospectus does not constitute an offer to sell or a solicitation of an offer to
buy any shares of common stock offered hereby in any jurisdiction in which such
an offer or a solicitation is unlawful.


     Sprout Capital VII, L.P., Sprout Growth II, L.P., DLJ First ESC L.P., The
Sprout CEO Fund, L.P. and DLJ Capital Corporation (collectively, the "Sprout
Entities") are affiliates of Donaldson, Lufkin & Jenrette Securities
Corporation, one of the underwriters. As described under "Principal and Selling
Stockholders," the Sprout Entities beneficially own an aggregate of 3,423,372
shares of the outstanding common stock, which represent more than 10% of the
outstanding common stock. Of these shares, approximately 2.1 million shares are
expected to become subject to a voting trust agreement prior to the completion
of the offering and are expected to be held and voted by an independent third
party, Norwest Bank Indiana, N.A., as voting trustee.


     Because the Sprout Entities affiliated with Donaldson, Lufkin & Jenrette
Securities Corporation beneficially own more than 10% of the outstanding common
stock, this offering is being conducted in accordance with Rule 2720 of the
Conduct Rules of the National Association of Securities Dealers, Inc., which
provides that the public offering price of an equity security be no higher than
that recommended by a "qualified independent underwriter" ("QIU") meeting
certain standards. In accordance with this requirement, BancBoston Robertson
Stephens has assumed the responsibilities of acting as QIU and will recommend a
price in compliance with the requirements of Rule 2720. In connection with this
offering, BancBoston Robertson Stephens is performing due diligence
investigations and reviewing and participating in the preparation of this
prospectus and the registration statement of which this prospectus forms a part.
Paradyne will pay BancBoston Robertson Stephens a fee of $5,000.00 in connection
with its services as QIU and will reimburse the QIU for its fees and expenses.
Paradyne has agreed to indemnify BancBoston Robertson Stephens, in its capacity
as the qualified independent underwriter, against certain liabilities, including
liabilities under the Securities Act.

     In connection with the offering, the underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of
Paradyne's common stock. Specifically, the underwriters may overallot the
offering, creating a syndicate short position. The underwriters may bid for and
purchase shares of common stock in the open market to cover such syndicate short
position or to stabilize the price of the common stock. In addition, the
underwriting syndicate may reclaim selling concessions from syndicate members
and selected dealers if they repurchase previously distributed common stock in
syndicate covering transactions, in stabilizing transactions or otherwise. These
activities may stabilize or maintain the market price of the common stock above
independent market levels. The underwriters are not required to engage in these
activities, and may end any of these activities at any time.

     There are restrictions on the offer and sale of the common stock in the
United Kingdom. All applicable provisions of the Financial Services Act 1986 and
the Public Offers of Securities Regulations 1995 with respect to anything done
by any person in relation to the common stock in, from or otherwise involving
the United Kingdom must be complied with.

     Each underwriter has also agreed that it has:

     - not offered or sold and prior to the date six months after the date of
       issue of the shares of common stock will not offer or sell any shares of
       common stock to persons in the United Kingdom except to persons whose
       ordinary activities involve them in acquiring, holding, managing or
       disposing of investments (as principal or agent) for the purpose of their
       businesses or otherwise in circumstances which have not resulted and will
       not result in an offer to the public in the United Kingdom within the
       meaning of the Public Offers of Securities Regulations 1995;

                                       80
<PAGE>   85

     - complied, and will comply with, all applicable provisions of the
       Financial Services Act 1986 of Great Britain with respect to anything
       done by it in relation to the shares of common stock in, from or
       otherwise involving the United Kingdom; and


     - only issued or passed on and will only issue or pass on in the United
       Kingdom any document received by it in connection with the issuance of
       the shares of common stock to a person who is of a kind described in
       Article 11(3) of the Financial Services Act 1986 (Investment
       Advertisements) (Exemptions) Order 1996 (as amended) of Great Britain or
       is a person to whom the document may otherwise lawfully be issued or
       passed on.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders of
Paradyne Networks, Inc.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of Paradyne
Networks, Inc. (formerly "Paradyne Acquisition Corp.") and its subsidiaries at
December 31, 1997 and 1998, and the results of their operations and their cash
flows for each of the two years in the period ended December 31, 1998 and for
the period from inception (August 1, 1996) through December 31, 1996 in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

            (IN THOUSANDS, EXCEPT SHARE DATA OR AS OTHERWISE NOTED)

1. BASIS OF PRESENTATION:

     Pursuant to a Purchase Agreement dated June 18, 1996 (the "Purchase
Agreement"), Paradyne Partners, L.P. ("Paradyne Partners") acquired certain
assets and operations of AT&T Paradyne Corporation from Lucent Technologies Inc.
("Lucent") for cash and seller notes totaling $146.0 million. This transaction
was consummated through five direct and indirect subsidiaries of Paradyne
Partners which included Paradyne Acquisition Corp. ("PAC") and its wholly-owned
subsidiary, Paradyne Corporation and its subsidiaries (the "Company"). The
acquisition was accounted for as a purchase. The purchase price was allocated to
the assets acquired and liabilities assumed based on fair values including
long-lived tangible and intangible assets. Property, plant and equipment,
purchased research and development and the Lucent supply agreement values were
based on independent appraised values.

     The following reflects a summary of the net assets acquired by the Company
at July 31, 1996:

<TABLE>
<S>                                                           <C>
Current assets..............................................  $ 52,957
Property, plant and equipment...............................    30,366
Purchased research and development..........................    13,114
Premisys contract...........................................     2,251
Lucent contract.............................................    25,441
Other non-current assets....................................     4,963
Current liabilities.........................................   (22,113)
Restructuring liability.....................................    (4,629)
                                                              --------
          Total.............................................  $102,350
                                                              ========
</TABLE>

     The restructuring liability related principally to involuntary employee
termination costs ($2.9 million) and costs of exiting surplus facilities ($1.5
million). Approximately $3.1 million of this liability was paid during 1996,
with the remaining $1.5 million paid during 1997.

     That portion of the acquired assets and operations of AT&T Paradyne
Corporation that remained with the Company were purchased for $102.3 million,
consisting of a $17.1 million equity investment, $69.3 million in seller notes
to Lucent, debt to the Paradyne Partners of $7.5 million and $8.4 million of
other acquisition costs.

     As further discussed in Note 15, subsequent to December 31, 1998, the legal
name of PAC was changed to Paradyne Networks, Inc. The accompanying financial
statements reflect the consolidated historical financial position, results of
operations and cash flows of Paradyne Networks, Inc., Paradyne and Paradyne's
wholly-owned subsidiaries from inception. Also, see Note 14 for discussion of
related party transactions.

     The Company is a leading developer, manufacturer and distributor of
broadband and narrowband network access products for network service providers
and business customers. The Company offers solutions that enable business class,
service level managed, high-speed connectivity over the existing telephone
network infrastructure.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     The significant accounting principles and practices used in the preparation
of the accompanying consolidated financial statements are summarized below:

  PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the results of
the Company and its wholly-owned subsidiaries: Paradyne Corporation; Paradyne
Canada Ltd.; Paradyne Japan Corporation; Paradyne International Ltd.; Paradyne
Worldwide Corp. (formerly Paradyne Far East Corporation); Ark Electronic
Products Inc.; Paradyne GmbH; and Paradyne International Sales Ltd. Intercompany
accounts and transactions have been eliminated in consolidation.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
            (IN THOUSANDS, EXCEPT SHARE DATA OR AS OTHERWISE NOTED)

  REVENUE RECOGNITION

     Revenue from equipment sales is generally recognized at the date of
shipment. Revenue from services, which consists mainly of repair of
out-of-warranty products, is recognized when the services are performed and all
substantial contractual obligations have been satisfied. Provision is made
currently for estimated product returns. Royalty revenue is recognized when the
Company has completed delivery of technical specifications and performed
substantially all required services under the related agreement. See discussion
of product warranty below.

  USE OF ESTIMATES

     The preparation of 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 revenues and expenses during the
reporting periods presented. Actual results could differ from those estimates.
The markets for the Company's products are characterized by intense competition,
rapid technological development and frequent new product introductions, all of
which could impact the future value of the Company's inventory and certain other
assets.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid instruments purchased with an
original maturity of three months or less to be cash equivalents.

  INVESTMENTS

     In accordance with Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities," the Company
has classified its equity securities as available-for-sale. These securities, of
which $2.1 million and $0 are included in prepaid expenses and other current
assets and $180 and $0 are included in other assets at December 31, 1997 and
1998, respectively, are stated at fair value, with the unrealized gain or loss,
net of taxes, reported in stockholders' equity until realized.

  CONCENTRATION OF CREDIT RISK

     The Company sells products to value added distributors and other customers
and extends credit based on an evaluation of the customer's financial condition,
generally without requiring collateral. Exposure to losses on receivables is
principally dependent on each customer's financial condition. The Company
monitors its exposure for credit losses and maintains allowances for anticipated
losses. Sales to one customer were approximately 42% of total revenues for the
five months ended December 31, 1996. Sales to two customers were approximately
34% and 12% of total revenues for the year ended December 31, 1997 and 35% and
15% of total revenues for the year ended December 31, 1998.

     Purchases from one vendor were approximately 37% of total purchases for the
five months ended December 31, 1996. Purchases from two vendors were
approximately 23% and 18% of total purchases for the year ended December 31,
1997 and purchases from one vendor were approximately 15% of total purchases for
the year ended December 31, 1998.

(a) Revenues are attributed to countries based on location of customer.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying value of the Company's financial instruments, which includes
cash, receivables and variable-rate debt, approximates fair value due to the
short maturities of those instruments.

  INVENTORIES

     Inventories are stated at the lower of cost or market. Cost includes
material, labor and manufacturing overhead. Cost is determined on a first in,
first out basis.

  INTANGIBLE ASSET

     Intangible asset, which consists of a contract with Premisys Communications
for exclusive distribution rights, is included in other assets (see Note 7).
This contract is amortized on a straight-line basis over the term of the
agreement of approximately four years. See Note 4 related to favorable supply
contract with Lucent, which was renegotiated. The original contract value was
based on estimated cash flows.

  PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are stated at cost. Leasehold improvements
are amortized on a straight-line method over the period of the lease or the
estimated service lives of the improvements, whichever is shorter. Depreciation
expense includes the amortization of capital lease assets.

     Expenditures for renewals and improvements that significantly add to
productive capacity or extend the useful life of an asset are capitalized.
Expenditures for maintenance and repairs are charged to operations

when incurred. When assets are sold or retired, the cost of the asset and the
related accumulated depreciation are eliminated from the accounts and any gain
or loss is recognized at such time.

  IMPAIRMENT OF LONG-LIVED ASSETS

     The Company evaluates the recoverability of its long-lived assets whenever
adverse events or changes in business climate indicate that the expected
undiscounted future cash flows from the related asset may be less than
previously anticipated. If the net book value of the related asset exceeds the
undiscounted future cash flows of the asset, the carrying amount would be
reduced to the present value of its expected future cash flows and an impairment
loss would be recognized in accordance with Financial Accounting Standards
No. 121. As of December 31, 1997 and 1998, management does not believe that an
impairment reserve is required.

  RESEARCH AND DEVELOPMENT COSTS

     Research and development costs are expensed as incurred. The Company
purchased in process research and development valued at $13.1 million which was
expensed during the period ended December 31, 1996. The purchased R&D was valued
based on projected discounted cash flows, on a project-by-project basis for 12
projects, using a risk adjusted discount rate of 22%. These projects were
scheduled for completion in late 1996 and 1997. There were no expected
significant variances from historical pricing, margins or expense levels in the
projections other than the normal decline in prices and margins as products age.

  PRODUCT WARRANTY

     The Company generally provides a return to factory warranty for a period of
two years from the date of sale. A current charge to income is recorded at the
time of sale to reflect the amount the Company estimates will be needed to cover
future warranty obligations for products sold during the year. The accrued
liability for warranty costs is included in the caption "other current
liabilities" in the accompanying consolidated balance sheet.

  INCOME TAXES

     The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes," which
requires use of the asset and liability method of accounting for deferred income
taxes.

  EARNINGS (LOSS) PER SHARE

     Basic earnings (loss) per share is computed by dividing income available to
common stockholders by the weighted average number of common shares outstanding
during the year. Diluted earnings per share assume the exercise of stock options
for which market price exceeds exercise price, less shares assumed purchased by
the Company with related proceeds.

     Options are not included in the 1998 calculation of diluted loss per share
due to their antidilutive effect.

  FOREIGN CURRENCY

     The local currency is the functional currency of each of the foreign
subsidiaries. Assets and liabilities of the Company's foreign subsidiaries are
translated using fiscal year-end exchange rates, and revenue and expenses are
translated using average exchange rates prevailing during the year. The effects
of translating foreign subsidiaries' financial statements are recorded as a
separate component of stockholders' equity.

     In addition, included in other (income) expense are realized foreign
currency exchange losses of $323 for the five months ended December 31, 1996 and
$596 for the year ended December 31, 1997. A foreign currency gain of $181 is
included for the year ended December 31, 1998.

  INTERIM FINANCIAL DATA

     The accompanying financial statements as of March 31, 1999 and for the
three months then ended are unaudited. In the opinion of management, these
interim statements have been prepared on the same basis as the audited financial
statements and include all adjustments, consisting only of normal recurring
adjustments, necessary for the fair presentation of the results of the interim
periods. The financial and other data disclosed in these notes to the financial
statements for these periods are also unaudited. The results of the operations
for the interim periods are not necessarily indicative of the results to be
expected for any future periods.

3. RESTRUCTURING CHARGES:

     The Company recorded a restructuring charge of $1.8 million related to
staff reductions in the U.S. operations in November 1997. Termination charges
related to approximately 93 employees spread throughout all major functions
within the Company. Staff reductions were necessary because the Company had
significantly improved operating efficiencies with its investment in new systems
and processes, as well as changing the composition of our workforce to update
the availability of strategic skills.

     In 1998, the Company recorded a restructuring charge of $984. This charge
related to the change in the Company's model for operating within certain
international operations. The Company now operates through a system of
distributors with branch operation support in most foreign locations. In this
restructuring approximately 25 employees were terminated from employment. In
addition, charges were incurred to exit from leased facilities in international
locations.

     During 1997 and 1998, the Company paid approximately $957 and $1.4 million
related to restructurings. The remaining $388 accrued as of year end, which is
expected to be paid during 1999, related to the international restructuring.

4. AMENDMENT TO LUCENT SUPPLY AGREEMENT:

     At July 31, 1996, Lucent delivered, as a condition to the closing specified
in Note 1, a four year Volume Purchase Letter ("VPL") whereby Lucent agreed to
purchase a baseline level of certain products or pay a penalty. At December 31,
1997 Lucent had not achieved the baseline commitment under the VPL and,
therefore, was subject to certain take-or-pay provisions. In August, 1998 the
Company, GlobeSpan Semiconductor Inc., a subsidiary of Paradyne Partners
("GlobeSpan"), and Lucent terminated the VPL including the elimination of all
existing and future minimum purchase requirements under a revised Exclusivity
and Amendment Agreement.

     As a result of the Exclusivity and Amendment Agreement, the Company
received $8.2 million in cash and $63.0 million of the outstanding note payable
to Lucent was forgiven. The Company also paid Lucent the remaining $2.7 million
outstanding under the existing terms of the note payable. In addition, GlobeSpan
agreed to amend the warrant originally granted to Lucent at the time of Paradyne
Partners' acquisition of GlobeSpan to acquire 1,500,000 shares of GlobeSpan by
extending the warrant term by three years, which would have expired upon
repayment of the seller notes. Additionally, Lucent and the Company agreed that
the Company will be Lucent's exclusive provider for certain access products for
resale through June 30, 2001.

     The contract renegotiation and resolution has been reflected in the
accompanying consolidated financial statements at December 31, 1997 and resulted
in a pretax gain of approximately $51.2 million and a contribution of capital by
Paradyne Partners of $3.6 million reflecting the estimated fair value of the
extension of the GlobeSpan warrant.

  REVOLVING CREDIT FACILITIES

     On July 31, 1996, the Company entered into an agreement (the "Agreement")
with a commercial lending institution to provide a revolving credit facility in
the amount of $45.0 million with availability subject to a borrowing base
formula. The facility provides for a sub-limit of $5.0 million for letters of
credit, of which none were outstanding at December 31, 1997 or 1998. The
Agreement includes a fee ranging from .375% to .50% of the unused line. Certain
assets of the Company, including accounts receivable, inventories, equipment and
intellectual property rights, are pledged as collateral. The Company is subject
to various non-financial covenants under the terms of the Agreement. Effective
December 31, 1997 and 1998, the Company was in compliance with or had obtained
waivers to the Agreement for such covenants.

     Additionally, the Agreement restricts the Company with respect to making
dividends.

     On August 25, 1997, the Company entered into a subordinated revolving
credit agreement (the "Credit Agreement") with Paradyne Partners. The Credit
Agreement made available $5.0 million through August 25, 2002. This agreement
was amended in October 1998 to make available $10.0 million. In connection
therewith, Paradyne Partners provided a limited continuing guarantee of the
Agreement. Borrowings under the Credit Agreement are subordinated to debt under
the Agreement and bears interest at 8% per annum. There were no borrowings under
this Credit Agreement as of December 31, 1998.

  CAPITAL LEASES

     The Company executed several long-term lease agreements for computer and
other equipment. For financial reporting purposes, the leases have been
classified as capital leases; accordingly, assets of approximately $1.2 million
(included in machinery and equipment) and accumulated depreciation of $283 have
been recorded at December 31, 1998.

     Future minimum lease payments for assets under capital leases at December
31, 1998 are as follows:

</TABLE>

     The Company recorded a valuation allowance at December 31, 1997 and 1998
with respect to the foreign net operating losses due to the uncertainty of their
ultimate realization.

     At December 31, 1998, Paradyne Canada had net operating loss carryforwards
of approximately $3.0 million expiring 2003. In the U.K. and Japan, management
has decided that operations will no longer be conducted through Paradyne
International Ltd. and Paradyne Japan Corporation, and thus, there will be no
future benefit related to the NOL carryforwards of Paradyne International Ltd.
and Paradyne Japan Corporation. The foreign net operating losses as of December
31, 1998 have been adjusted to reflect the elimination of loss carryforwards
related to the exit of these foreign subsidiaries.

11. STOCK OPTION PLAN:

     The Company has a stock option plan (the "1996 Plan") whereby the Board of
Directors may discretionarily reserve common shares for the purpose of granting
to employees (including officers and employee directors) or the employees of the
Company's affiliates, options to purchase common stock. Nonstatutory stock
options, rights to acquire restricted stock and stock bonuses may be granted to
employees (including officers), directors of and consultants to the Company or
its affiliates. Under the plan, 6,000,000 shares have been reserved related to
options available for grant to employees, directors and consultants through
December 31, 1998. The options are generally fully vested in four years, and
they have a maximum contractual life of 10 years. The exercise price of options
granted under the 1996 Plan are determined by the Board of Directors. The
Company has granted 4,731,025 options to the Company's employees, directors and
consultants of which 4,028,047 options are outstanding as of December 31, 1998.

     During 1998, the Company granted 47,950 fixed options to purchase shares of
common stock with exercise prices below fair market value. As a result, $96 of
compensation expense will be recognized ratably over the vesting period of the
related options, of which $6 was recognized in 1998.

     Information on stock options is summarized as follows:

     The preceding pro forma results were calculated with the use of the Black
Scholes option pricing model. The following assumptions were used for the years
ended December 31, 1997 and 1998: (1) risk-free interest rate of 6.60%; (2)
dividend yield of 0.0%; (3) expected life of 5.0 years; and (4) volatility of
0.0001%.

     At December 31, 1998 the Company has 73,800 options issued to employees at
a weighted average price of $2.13 which vest only in the event of an initial
public offering of the Company's common stock. Accordingly, in the event of an
initial public offering compensation expense will be recorded to the extent fair
value exceeds the option price.

     During the first quarter of 1999, the Company issued options to acquire
52,200 shares of the Company's common stock at a weighted average price of $5.00
per share, which was less than fair value by $271, and which is being amortized
ratably over the vesting period. During the three months ended March 31, 1999,
$17 of compensation expense has been included in selling, general and
administrative expenses for all stock options issued at less than fair market
value.

     During March 1999, various executives of the Company issued full recourse
promissory notes, totaling $939 to the Company in connection with the purchase
of 394,938 shares of common stock. Additionally, in May 1997, an executive
issued a full recourse promissory note in the amount of $150 in connection with
the purchase of 75,000 shares of common stock. The principal balance of the
notes and the related accrued interest (4.72% and 6.65% per annum) are payable
at the earlier of the termination of employment or five years from the date of
the note. The notes are secured by the shares of common stock acquired with the
notes, and those shares are held in escrow by the Company. All unvested shares
purchased with the notes are subject to repurchase by the Company if the
respective executive terminates their employment before becoming fully vested.
The balance as of March 31, 1999 was $1.1 million plus accrued interest.

GlobeSpan under a non-cancelable operating lease. Future minimum lease payment
receivables under the leasing agreement as of December 31, 1998 are as follows:
1999 -- $934; 2000 -- $934; 2001 -- $955; 2002 -- $352; 2003 and $0 thereafter
(see Note 14).

  SALE/LEASEBACK

     In June 1997, the Company sold all of its land and the improvements thereon
at its Largo, Florida facility at approximately net book value, and at the same
time leased back two of the buildings. The primary term of the lease is for 10
years with annual rents approximating $1.8 million for the first five years and
$2.1 million for the remaining five years. If the buildings are sold within
three years of acquisition, the primary lease term will be 12 years. The Company
has the option to renew the lease for two additional five year terms on the same
conditions as the current lease. The Company is responsible for paying for any
necessary improvements to the property and is responsible for its proportionate
share of most operating costs and taxes on the property.

  SALE OF INSTALLMENT RECEIVABLES

     At December 31, 1998, sales-type lease receivables sold to AT&T Capital
Corporation with recourse were $886. The ultimate responsibility for the
collection of these receivables is with Paradyne Credit Corp., a related party.

13. EMPLOYEE BENEFITS:

     401(k) Plan

     The Company has a 401(k) plan covering substantially all employees of the
Company. Benefits vest based on number of years of service. The Company's policy
is to match two-thirds of an employee's contributions, up to six percent of an
employee's annual salary. Additionally, the Board of Directors may grant
discretionary contributions. Contributions to the plan were approximately $1.1
million, $2.4 million and $2.4 million for the five months ended December 31,
1996 and the years ended December 31, 1997 and 1998, respectively.

     Key Employee Stock Option Plan

     The Key Employee Stock Option Plan (the "Key Employee Plan") was adopted in
December 1997, and covers employees holding the position of Vice President or
above. Key Employee Plan participants may elect to defer a portion of their
annual compensation in exchange for options to purchase shares of common or
preferred stock of any publicly-traded corporation, shares of the Company's
common stock or shares in

certain investment funds. Upon the grant of an option under the Key Employee
Plan, the Company is required to acquire and hold under a trust arrangement,
shares of the stock or investment subject to the option in a number equal to 75%
of the shares subject to option.

14. RELATED PARTY TRANSACTIONS:

     On December 30, 1996, the Company purchased certain installment and
affiliate receivables in the amount of $14.0 million from Paradyne Credit Corp.
("PCC"), a subsidiary of Paradyne Partners, in exchange for a note payable of
$13.7 million. A deferred gain of $291 is included in other current liabilities
at December 31, 1996. The note bore an interest rate of 9.25% and matured
December 30, 1997. The Accounts Receivable Purchase and Servicing Agreement
allowed the Company to require PCC to repurchase the receivables prior to the
due date of the note. On January 3, 1997, the Company sold the receivables back
to PCC in exchange for cancellation of the note payable.

     Notes payable to affiliate were owed to Paradyne Partners. As further
discussed in Note 9, the Company executed a revolving subordinated credit
agreement with Paradyne Partners in fiscal 1997. The Company recorded interest
expense of approximately $267, $421 and $305 related to these notes during the
five months ended December 31, 1996 and the years ended December 31, 1997 and
1998, respectively.

     The Company provides operating, management and other administrative
services for certain subsidiaries of Paradyne Partners. Total charges to these
entities were approximately $432 for the five months ended December 31, 1996 and
$1.1 million and $1.4 million for the years ended December 31, 1997 and 1998,
respectively. This amount is recorded as a reduction of general and
administrative expenses.

     PCC had an option to acquire all used equipment owned by the Company and
its subsidiaries for which the original lease had expired or terminated.
Additionally, the option allowed PCC to purchase all used equipment which had
been returned from sales to customers or consignment activities. The exercise
price of the option was equivalent to one month's rental revenue from the
related equipment. Purchases of such equipment totaled $115, $81 and $0 for the
five months ended December 31, 1996 and the years ended December 31, 1997 and
1998, respectively. In 1997, the Company sold all equipment under leases, as
well as the related lease streams, to PCC in exchange for approximately $3.5
million. As a result of this sale, the option is no longer valid.

     In connection with this sale of equipment and related lease streams to PCC
in 1997, the Company entered into an agreement to allow PCC to purchase
equipment manufactured or sold by the Company at prices substantially equal to
those received by the Company through normal selling channels. Purchases under
this agreement totaled $181 and $317 for the years ended December 31, 1997 and
1998, respectively. Additionally, this agreement provides for the Company to
purchase from PCC equipment that has been returned to PCC at the end of the
lease. These purchases are on terms no more favorable to the Company than would
be obtained in a comparable arm's length transaction. Purchases for such
equipment totaled $0 and $141 for the years ended December 31, 1997 and 1998,
respectively.

     The Company entered into a license agreement with GlobeSpan for the use of
certain technologies. Total royalty expense related to the use of these
technologies was approximately $235 for the five months ended December 31, 1996
and $0 for each of the years ended December 31, 1997 and 1998. This amount has
been included in equipment cost of sales. In November 1996, the Company entered
into a Cooperative Development Agreement with GlobeSpan. Under this agreement,
the Company was granted an unrestricted license to use GlobeSpan's technical
information and patents. Additionally, the agreement provided for the Company to
purchase GlobeSpan chip sets at prices not to exceed cost plus 15%. The Company
purchased goods approximating $0, $373 and $962 during the period ended December
31, 1996 and the years ended December 31 1997 and 1998, respectively, under this
agreement. Effective July 1998, the Company revised its pricing arrangement with
GlobeSpan such that GlobeSpan sold products to the Company at preferential

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

prices. In exchange, GlobeSpan agreed to pay a 1.25% royalty based on net
revenues up to an aggregate amount of $1.5 million. The Company recorded $381 of
royalty revenue related to the agreement during the year ended December 31, 1998
(see Note 15).

     Beginning in August 1996, GlobeSpan participates in a 401K plan which is
maintained by the Company. Contributions paid by the Company on behalf of
GlobeSpan approximated $65, $321 and $379 for the five months ended December 31,
1996 and the years ended December 31, 1997 and 1998, respectively. GlobeSpan has
reimbursed the Company for all payments made on their behalf.

     In 1996 and 1997, the Company provided the use of certain assets to
GlobeSpan related to their research activities without material fee.
Depreciation of $106 in 1996 and $244 in 1997 related to those assets has been
excluded from the results of operations and reflected as a distribution of
equity to a related party. Those assets were subsequently sold to GlobeSpan. The
Company sold fixed assets to GlobeSpan for approximately $350 in fiscal year
1997 and $1.4 million in fiscal 1998. These assets were transferred at their
approximate net book values since the transaction involved entities under common
control.

     In 1997, the Company received $194 from GlobeSpan as reimbursement for
purchases of product from a supplier on behalf of GlobeSpan. In December 1997
and September 1998, the Company sold to GlobeSpan certain chip sets which it
held in its inventory in the amounts of $98 and $29, respectively. GlobeSpan
purchased these chip sets for resale to other customers.

     In May 1997, an executive of the Company issued a promissory note in the
amount of $150 in connection with the purchase of 75,000 shares of common stock.
The full recourse note accrues interest of a rate of 6.65% per annum. The
principal balance and accrued interest are payable at the earlier of the
termination of employment or five years from the date of the note. The note is
secured by the shares of common stock acquired with the note.

     In December 1998, the Company subleased additional office space to
GlobeSpan (see Note 12). Also see Note 4 regarding GlobeSpan warrant extension
and Note 9 regarding parent company debt guaranty. In connection therewith,
GlobeSpan reimbursed approximately $392 of the Company's moving expenses.

15. SUBSEQUENT EVENTS:

     In March 1999, the Company and GlobeSpan agreed to terminate the
Cooperative Development Agreement ("Termination Agreement") effective December
31, 1998 (see Note 14). In connection with such termination agreement, GlobeSpan
agreed to pay the Company an aggregate of $1.5 million. Of this amount,
approximately $400 was recorded in 1998 and included in royalty revenue. The
remaining $1.1 million is expected to be received in 1999 and is included in
royalty revenue and receivable from affiliates as of March 31, 1999. In
addition, GlobeSpan and the Company as part of the Termination Agreement
affirmed that the earlier technology license provisions of the Cooperative
Development Agreement were never implemented. In conjunction with the signing of
the Termination Agreement, GlobeSpan and the Company also entered into a
four-year Supply Agreement which gave the Company favorable pricing and other
terms in connection with the sale by GlobeSpan of products to the Company. In
addition, under the terms of the Supply Agreement, GlobeSpan is required to
honor the Company's orders for GlobeSpan's products in quantities at least
consistent with the Company's past ordering practices and must afford the
Company at least the same priority for the Company's orders as GlobeSpan affords
its other similarly situated customers. GlobeSpan also granted the Company a
standard customer immunity under GlobeSpan's intellectual property rights with
respect to any of the Company's products which incorporate GlobeSpan's products.

     Effective February 25, 1999, Paradyne Partners was renamed Communication
Partners, L.P. In March 1999, the Company voluntarily reduced the amount
available for borrowing under its revolving credit facility

to $35.0 million and Communication Partners' continuing limited guaranty under
the facility was canceled (see Note 9).

     During April 1999, the Company issued options to acquire 213,250 shares of
the Company's common stock at $5.00 per share, which is less than fair value by
$1.4 million, and which is being amortized ratably over the vesting period.

     Effective April 1, 1999, the intercompany services agreement between the
Company and Paradyne Credit Corporation ("PCC") was amended to provide that
Paradyne will charge PCC for all direct and indirect costs incurred on behalf of
PCC by Paradyne plus a 5% service charge on all charges.

     In March 1999 the Company recorded $1.5 million from the License and
Assignment Agreement ("Telogy Agreement") entered into with Telogy Networks,
Inc. which is included in royalty revenue for the three months ended March 31,
1999. Finder's fees in connection with the Telogy Agreement in the amount of
$225 or 15% of revenue were paid to a third party and are included in selling,
general and administrative expenses. The Telogy Agreement further provided for
the sale of intellectual property in the amount of $3.5 million which is
included in other income net of $525 or 15% in finder's fees.

     In March and April of 1999, 10 employees of the Company issued promissory
notes to the Company in the amount of $1.0 million in connection with the
purchase of 411,187 shares of common stock. The full recourse notes accrue
interest at rates ranging from 4.72% to 5.15% per annum. The principal balance
and accrued interest are payable at the earlier of the termination of employment
or five years from the date of the note. The notes are secured by the shares of
common stock acquired with the note.

     In June 1999, the Board of Directors adopted the 1999 Employee Stock
Purchase Plan (the "Purchase Plan"). Under the Purchase Plan, the Company is
authorized to issue up to 1,000,000 shares of common stock to eligible
employees. Employees may elect to have up to 15% of their earnings withheld. The
amounts withheld are used to purchase shares of common stock, on specified dates
determined by the Board of Directors, at 85% of the lower of the fair market
value of the common stock at the commencement date of each offering period or
the relevant purchase date.

     Also in June 1999, the Board of Directors adopted the 1999 Non-Employee
Directors' Stock Option Plan (the "Directors' Plan") and reserved 250,000 shares
under the plan to provide for the automatic grant of options to purchase shares
of common stock to non-employee directors of the Company. Each non-employee
director will be granted an initial grant upon appointment. Annual grants of an
additional 5,000 shares will be made to any of the non-employee directors,
subject to attendance of regularly scheduled meetings of the Board as described
in the plan.

     On June 8, 1999, the Company changed its legal name from Paradyne
Acquisition Corp. to Paradyne Networks, Inc., which change has been reflected in
the accompanying consolidated financial statements. At the same time, the
Company's Board of Directors authorized a 1-for-2 reverse split of its common
stock, with no change in par value. All share and per-share amounts in the
accompanying consolidated financial statements have been restated to give effect
to the stock split.

     Also in June 1999, the Board of Directors authorized 5,000,000 shares of
preferred stock, with a par value of $0.001 per share.

                         NOTES TO FINANCIAL STATEMENTS
                                 (IN THOUSANDS)

1. BASIS OF PRESENTATION:

     Pursuant to a Purchase Agreement dated June 18, 1996 (the "Purchase
Agreement"), Paradyne Partners, L.P. ("Paradyne Partners") acquired certain
assets and operations of AT&T Paradyne Corporation from Lucent Technologies Inc.
("Lucent") for cash and seller notes totaling $146 million. This transaction was
consummated through five direct and indirect subsidiaries of Paradyne Partners
which included Paradyne Acquisition Corp. ("PAC") and its wholly-owned
subsidiary, Paradyne Corporation and its subsidiaries (the "Company"). The
Company acquired certain net assets of AT&T Paradyne Corporation relating to the
manufacturing, marketing and research activities for data communications and
networking products for commercial end users and network service providers and
also entered into a product distribution agreement with Lucent.

     The accompanying financial statements include the accounts of Paradyne
Predecessor Business (a carve-out business of AT&T Paradyne Corporation), which
were acquired by the Company, on a carved-out basis as if it had been an
independent reporting entity for the period presented. See discussion of related
party transactions in Note 4.

     The Company designs, manufactures and markets data communications and
networking products for commercial end users and network service providers. The
Company's products enable commercial end users to efficiently access wide area
network services and allow network service providers to provide customers with
high-speed services for data, voice, video and multimedia applications.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     The significant accounting principles and practices used in the preparation
of the accompanying financial statements are summarized below:

  PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the net assets
and the results of operations acquired from AT&T Paradyne Corporation and its
wholly-owned subsidiaries: Paradyne Canada Ltd.; Paradyne Japan Corporation;
Paradyne International Ltd.; Paradyne Worldwide Corp. (formerly Paradyne Far
East Corporation); Ark Electronic Products Inc.; and Paradyne GmbH. Intercompany
accounts and transactions have been eliminated in consolidation.

  USE OF ESTIMATES

     The preparation of 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 revenues and expenses during the
reporting periods presented. Actual results could differ from those estimates.
The markets for Paradyne Predecessor Business' products are characterized by
intense competition, rapid technological development and frequent new product
introductions, all of which could impact the future value of Paradyne
Predecessor Business' inventory and certain other assets.

  REVENUE RECOGNITION

     Revenue from equipment sales is generally recognized at the date of
shipment and revenue from services is recognized when the services are performed
and all substantial contractual obligations have been satisfied. See discussion
of product warranty below.

                                      F-25

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                                 (IN THOUSANDS)

  CASH AND CASH EQUIVALENTS

     Paradyne Predecessor Business considers all highly liquid instruments
purchased with an original maturity of three months or less to be cash
equivalents.

     Expenditures for renewals and improvements that significantly add to
productive capacity or extend the useful life of an asset are capitalized.
Expenditures for maintenance and repairs are charged to operations when
incurred. When assets are sold or retired, the cost of the asset and the related
accumulated depreciation are eliminated from the accounts and any gain or loss
is recognized at such time.

  RESEARCH AND DEVELOPMENT COSTS

     Research and development costs are expensed as incurred.

  PRODUCT WARRANTY

     Paradyne Predecessor Business generally provided a return to factory
warranty for a period of two years from the date of sale. A current charge to
income is recorded at the time of sale to reflect the amount it estimates will
be needed to cover future warranty obligations for products sold during the
year.

  INCOME TAXES

     Paradyne Predecessor Business joined with AT&T Paradyne Corporation in
filing state income tax returns (and with Lucent in cases where consolidated
state income tax returns were filed), and with Lucent, AT&T Paradyne
Corporation's parent, in filing consolidated Federal income tax returns.

     The tax provision of $184 reflected in the accompanying statement of
operations relates to the foreign tax obligations of AT&T Paradyne's foreign
subsidiaries.

  CONCENTRATION OF CREDIT RISK

     Paradyne Predecessor Business sells products to value added distributors
and other customers and extends credit based on an evaluation of the customer's
financial condition, generally without requiring collateral. Exposure to losses
on receivables is principally dependent on each customer's financial condition.
Paradyne Predecessor Business monitors its exposure for credit losses and
maintains allowances for anticipated losses. Accounts receivable from one
customer was approximately $3,842 (15%) of total accounts receivable at July 31,
1996. Sales to two customers were approximately $35,290 (25%) and $16,580 (12%)
of total revenues for the seven months ended July 31, 1996.

     Purchases from two vendors were approximately $15,009 (25%) and $7,836
(13%) of total inventory purchases for the seven months ended July 31, 1996.

  FOREIGN CURRENCY

     The local currency is the functional currency of each of the foreign
subsidiaries. Assets and liabilities of Paradyne Predecessor Business' foreign
subsidiaries are translated using fiscal year-end exchange rates, and revenue
and expenses are translated using average exchange rate prevailing during the
year. Included in other income are realized foreign currency exchange losses of
$656 for the seven months ended July 31, 1996.

3. COMMITMENTS AND CONTINGENCIES:

     Paradyne Predecessor Business is obligated under non-cancelable operating
leases for office and warehouse equipment and facilities. The leases expire at
various dates through 2002. Rent expense for the seven months ended July 31,
1996 approximated $1,519. Minimum required future lease payments under non-
cancelable operating leases are as follows:

4. RELATED PARTY TRANSACTIONS:

     Sales to Lucent Technologies and AT&T Paradyne Corporation were $16,580 and
$35,290, respectively. Inventory purchases from Lucent Technologies totaled
$5,547.

     Paradyne Predecessor Business made payments to Lucent to participate in
Lucent's pension, 401(k), and other post employment benefit (mainly health) and
retirement plans in the amounts of $2,933, $1,146, and $910, respectively.

     Contract services for various administrative and sales support functions
were provided by Lucent to Paradyne Predecessor Business. The total contract
expenses charged to AT&T Paradyne for the period were $2,696, which was included
in operating expenses. Management believes that such amounts are reasonable and
include all significant costs incurred to support this company.

     During the seven months ended July 31, 1996, AT&T Paradyne recorded
approximately $146 in interest expense related to outstanding intercompany
advances from Lucent Technologies.

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

     Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its Directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act.

     The Registrant's Certificate of Incorporation and Bylaws include provisions
to (i) eliminate the personal liability of its directors for monetary damages
resulting from breaches of their fiduciary duty to the extent permitted by
Section 102(b)(7) of the General Corporation Law of Delaware (the "Delaware
Law") and (ii) require the Registrant to indemnify its Directors and officers to
the fullest extent permitted by Section 145 of the Delaware Law, including
circumstances in which indemnification is otherwise discretionary. Pursuant to
Section 145 of the Delaware Law, a corporation generally has the power to
indemnify its present and former directors, officers, employees and agents
against expenses incurred by them in connection with any suit to which they are,
or are threatened to be made, a party by reason of their serving in such
positions so long as they acted in good faith and in a manner they reasonably
believed to be in or not opposed to, the best interests of the corporation and
with respect to any criminal action, they had no reasonable cause to believe
their conduct was unlawful. The Registrant believes that these provisions are
necessary to attract and retain qualified persons as Directors and officers.
These provisions do not eliminate the Directors' duty of care, 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 Registrant, for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
acts or omissions that the Director believes to be contrary to the best
interests of the Registrant or its stockholders, for any transaction from which
the Director derived an improper personal benefit, for acts or omissions
involving a reckless disregard for the Director's duty to the Registrant or its
stockholders when the Director was aware or should have been aware of a risk of
serious injury to the Registrant or its stockholders, for acts or omissions that
constitute an unexcused pattern of inattention that amounts to an abdication of
the Director's duty to the Registrant or its stockholders, for improper
transactions between the Director and the Registrant and for improper
distributions to stockholders and loans to Directors and officers. The provision
also does not affect a Director's responsibilities under any other law, such as
the federal securities law or state or federal environmental laws.

                                      II-1
<PAGE>   115

     At present, there is no pending litigation or proceeding involving a
Director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any officer or Director.

     The Registrant has an insurance policy covering the officers and Directors
of the Registrant with respect to certain liabilities, including liabilities
arising under the Securities Act or otherwise.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

     Since June 14, 1996, Registrant has issued and sold the following
securities, which numbers do not reflect the 1-for-2 reverse split Registrant's
common stock to be effected prior to this offering:

          (1) On June 14, 1996, Registrant issued 1,000 shares (not accounting
     for the 17,000 for 1 split effected on January 7, 1997 or the 3 for 1 split
     effected on April 24, 1997) in a private placement of its common stock at a
     purchase price of $1.00 per share, for cash in the aggregate amount of
     $1,000, to Communication Partners, L.P. pursuant to the divestiture of
     Paradyne.

          (2) As of May 15, 1999, Registrant has sold and issued 812,508 shares
     of its common stock to employees, officers and directors pursuant to direct
     issuances and exercises of options under its 1996 Equity Incentive Plan.

     The sale of the above securities was deemed to be exempt from registration
under the Securities Act in reliance upon Section 4(2) of the Securities Act or
Rule 701 promulgated under Section 3(b) of the Securities Act as transactions by
an issuer not involving any public offering or transactions pursuant to
compensation benefit plans and contracts relating to compensation as provided
under such Rule 701. 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 share certificates issued in such
transactions. All recipients had adequate access, through their relationships
with the Registrant, to information about the Registrant.

 (B) INDEX TO FINANCIAL STATEMENT SCHEDULES

     The following financial statement schedule is included in this Registration
Statement:

     Report of Independent Certified Public Accountants on Financial Statement
Schedule

     Schedule II -- Valuation and Qualifying Accounts

ITEM 17.  UNDERTAKINGS

     The undersigned registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to provisions described in Item 14 or otherwise, the registrant has
been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

     The undersigned Registrant hereby undertakes:

          (1) That, for purposes of determining any liability under the 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 Act shall be deemed to be part of this Registration
     Statement as of the time it was declared effective.

          (2) That, for purposes of determining any liability under the Act each
     post-effective amendment that contains a form 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.

                  For the purpose of this Agreement, "Material" shall be defined
as those services performed by Supplier for Company and those communications
products that are identified by comcode numbers and described on Exhibit A to
this Agreement ("Existing Products"); which attachment shall be continuously
updated, to include Enhanced and New Products if such products satisfy the
requirements of the clause ENHANCED AND NEW PRODUCTS.

4.       ENHANCED AND NEW PRODUCTS

                  For the purpose of this Agreement, "Enhanced Product" or
"Enhanced Products" shall mean any product which results out of Company's desire
to have Supplier redesign, modify, or enhance an Existing Product or family of
Existing Products. For the purpose of this Agreement, "New Product" or "New
Products" shall mean any product which is not an Enhanced Product or Existing
Product but which is substantially similar to an of this Agreement, "New
Product" or "New Products" shall mean any product which is not an Enhanced
Product or
<PAGE>   2
Existing Product but which is substantially similar to an Existing Product with
respect to design and function and possesses reasonable performance
improvements. If Company desires to purchase an Enhanced or New Product(s) from
Supplier, Company shall so notify Supplier and provide Supplier the opportunity
to manufacture such Enhanced or New Product(s), subject to the following
conditions and procedures.

                  Supplier shall, within thirty (30) days from the date of
Supplier's receipt of Company's notice, inform Company whether Supplier desires
to manufacture and supply such Enhanced or New Product(s) to Company. If
Supplier desires to manufacture and supply such Enhanced or New Product(s),
Supplier shall provide Company (a) a written production plan demonstrating
Supplier's ability to satisfy the Performance Requirement, as described in the
next sentence, for such Enhanced or New Product(s) (such plan shall include
production locations and proposed dates for prototypes, sample production and
full production) and (b) Supplier's proposed Price for such Enhanced or New
Product(s). "Performance Requirement" shall mean the Company's reasonably
prescribed performance standards for Material, including, but not limited to,
quality, compliance with Specifications, delivery and service support, each
determined in the case of an Enhanced Product with reference to standards for an
Existing Product or family of Existing Products.

                  The parties shall then negotiate in good faith to reach an
agreement on such production plan's ability to satisfy the Performance
Requirements and the Price to be charged for the Enhanced or New Product(s). In
the event the parties agree on the production plan's satisfaction of the
Performance Requirement and the Price for such Enhanced or New Product(s), and
Supplier fulfills its obligations under the production plan (including the
commencement of full production runs), then such Enhanced or New Product(s) will
be added to Exhibit A for the purposes of this Agreement. All work performed by
Supplier under this clause will be at Supplier's sole risk and expense, unless
otherwise agreed to by the parties.

                  If despite good faith negotiations the parties fail to agree
(i) that the Enhanced or New Product(s) production plan satisfies the
Performance Requirement or (ii) on a Price for the Enhanced or New Product(s),
the parties agree to resolve the dispute through mediation as set forth in the
Clause MEDIATION. In the event that as a result of such mediation, if necessary,
the production plan is deemed to not satisfy the Performance Requirement, or the
product plan slips the Company may purchase the Enhanced or New Product(s) from
another source or sources and, the Volume/Price levels as outlined in the
("Volume/Price Letter") shall be adjusted to reflect the dollar amount purchased
by Company from the other source or sources.

                  If the Supplier desires not to make available for order by
Company any Enhanced or New Product, the Company may purchase the Enhanced or
New Product(s) from another source or sources and, the Volume/Price levels as
outlined in the Volume Price Letter shall be adjusted to reflect the dollar
amount purchased by Company from the other source or sources.

5.       MATERIAL PURCHASE

                  During the term of this Agreement, Company shall purchase and
Supplier shall sell Material to Company in accordance with the terms and
conditions set forth in this Agreement and the Exhibits shown which are hereby
made a part of this Agreement.

                  In the event the terms and conditions of the Exhibits shown
above conflict with the terms and conditions of the Agreement, the terms and
conditions of this Agreement shall prevail.

6.       PRICE


                  For the purposes of this Agreement, the "Price" for Material
shall mean base price less the applicable Company discount and shall be as set
forth on Exhibit A which attachment shall be revised from time to time as
provided in this Agreement. Supplier agrees to accept Orders directly from any
of Company's subcontractors as designated by Company and extend to Company's
subcontractors the Prices set forth for Material.


7.       BEST PRICE


                  Supplier's Prices to Company for Material contained herein
with applicable discounts and with any increases permitted hereunder, shall be
at least as low as those Prices (with applicable discounts) offered by Supplier
to any of its customers for comparable Material and services in comparable
quantities and terms. If Supplier at any time extends to any other customer
lower Prices or higher discounts for comparable quantities and material under
comparable terms, Supplier shall promptly notify company of such Prices or
discounts and grant to Company the benefit of such Price or discounts for all
Material sold to Company retroactive to the effective date of Supplier's Price
or discount arrangement with its other customer. For purposes of determining if
Supplier's prices are Best Prices, within the meaning of this paragraph only.
Supplier's Prices shall [***].


8.       MARKET RIGHTS

                  Company has selected Supplier as a preferred supplier for the
Material described in Exhibit A during the four (4) year term of this Agreement.
"Preferred Supplier" means that Company will use commercially reasonable efforts
to purchase Material from Supplier over equivalent (i.e., price, functionality
or performance) material offered by another supplier pursuant to the terms and
conditions of this Agreement. Except for the Preferred Supplier status described
in the foregoing sentence, it is expressly understood and agreed that this
Agreement neither grants to Supplier an exclusive right or privilege to
manufacture, repair, or source all Material of the type described in this
Agreement, nor requires the purchase of any manufactured, repaired, or sourced
Material from Supplier by Company. It is, therefore, understood that Company may
contract with other manufacturers and suppliers for the manufacture or repair of
Material and other products.

9.       BENCHMARKING

                  On a semi-annual basis, or "as needed" by either party,
Supplier and Company shall undertake to benchmark price, quality, product
functionality, and service performance of the Material

offered by Supplier here under. The Material benchmarked shall be the comcodes
that comprise [***] purchased by Company. Supplier and Company shall review such
benchmark information and Supplier shall develop a plan of action for improving
Material Price, quality, product functionality, and service performance if such
benchmark information indicates improvements are needed when compared to the
then existing standards of the industry of comparable Price, quality, product
functionality and service. Should Supplier fail to introduce improvements that
assure Company that Material is meeting or exceeding competitive benchmarks with
respect to: (1) Material Price within ten (10) days of such review, and (2) for
Material quality, product functionality, or service performance within ninety
(90) days of such review (with Supplier to provide a plan for introducing such
improvements within the first thirty (30) days of such review) then Company
shall have the right to competitively quote such Material in the marketplace.
Company will give Supplier a thirty (30) day prior written notice of an intent
to place business with any other supplier and provide Supplier that thirty (30)
day period to match or beat such other offer received by Company. If Supplier
matches or beats such other offer, Company agrees to continue to place Orders
with Supplier at the new Price, quality, product functionality, and service
levels subject to the terms and conditions of this Agreement. If Supplier does
not match or beat Company's offer, Company may elect to purchase Material from
another source and the Volume/Price levels set forth in the Volume Price Letter
shall be adjusted to reflect the dollar amount purchased by Company from the
other source or sources.

                  In the event of a dispute with respect to the approach,
procedures or results of the benchmarking, the parties agree to promptly retain
an independent, nonaffiliated consultant experienced in the industry to provide
an objective assessment of the issue(s) in dispute. The determination of the
consultant shall be final and binding.

10.      PAYMENT TERMS

conditions of Company's Demand Pull, Pull Replenishment, and Consignment
arrangements are set forth on Exhibits B, C and D of this Agreement.

13.      FLEXIBLE ORDERING AND PAYMENT ARRANGEMENTS

                  During the term of this Agreement, Company may give written
notice to Supplier requesting that Supplier implement Electronic Data
Interchange ("EDI") ordering and payment arrangements for one or more types of
Material. Upon mutual agreement between Company and Supplier, Company shall have
the right to implement such ordering and payment arrangements by providing
written notice to Supplier at least thirty (30) days prior to the implementation
date. Such notice shall specify the particular Company facility which will be
covered by such ordering and payment arrangement, the Material covered by such
ordering and payment arrangement and the requested implementation date. The
parties acknowledge and agree that the implementation of an EDI program will
entail the cooperation of both parties and that such parties will work in good
faith to implement such program as soon as practicable. The proposed terms and
conditions of the applicable ordering and payment arrangement are set forth on

by the parties are hereby made a part of this Agreement. Specifications may be
modified from time to time with agreement of the parties and the parties shall
promptly endeavor to mutually agree to equitable adjustments to the Price and/or
delivery schedules resulting from any such modifications. Supplier shall
manufacture Material in accordance with Specifications, so that Material
conforms to such Specifications.

                  Company's ownership, design, inspection, and/or approval of
Material shall in no way limit Supplier's responsibility for its obligations
under this or any other part of this Agreement.

15.      MANUFACTURE DISCONTINUED

                  Supplier shall provide Company at least one (1) year prior
written notice that any Material covered by this Agreement is recommended as a
candidate to be manufacture discontinued by Supplier. Company shall, within
sixty (60) days after receipt of Supplier's written notice, provide Supplier a
written response indicating Company's approval or disapproval of the manufacture
discontinued status of such Material based upon such Material's impact on the
Company's business, including but not limited to the Company's obligations to
its customers.

                  If Company does not approve of the Material being manufacture
discontinued, the parties shall negotiate in good faith to determine the final
disposition of such Material.

                  If the parties agree that Material shall become manufacture
discontinued, Supplier shall accept Company's Orders for such manufacture
discontinued Material under the terms and conditions of this Agreement for one
(1) year from the Supplier's notification date of manufacture discontinued
status. Once the manufacture discontinued Material is no longer available to
order

26.      UTILIZATION OF MINORITY AND WOMEN OWNED BUSINESS ENTERPRISES

                  It is Company's policy that Minority and Women-Owned Business
Enterprise ("MWBEs") shall have the maximum practicable opportunity to
participate in the performance of contracts. Supplier agrees to use its good
faith efforts to award subcontracts to carry out this policy to the fullest
extent consistent with the efficient performance of this Agreement. Supplier
agrees to conduct a program which will enable MWBEs to be considered fairly as
subcontractors and suppliers under this Agreement. Supplier shall submit to
Company periodic reports of subcontracting with known MWBEs in such manner and
at such time (not more than quarterly) as Company's representative may
prescribe. Such periodic report shall state separately for Minority and Women
Owned Businesses the subcontracted work which is attributable to Company. In
instances where direct correlation cannot be determined, such MWBE payments may
be established by Supplier comparing Company's payments to Supplier, in that
period, to total payments to Supplier from all of its customers, in that period,
and then arriving at Company's apportionment of such MWBE payments. Nothing in
this clause shall affect or diminish the Supplier's obligations as set forth in

Percent Received By Lead Time and an Average Percent Received To Required Date
(Past And Current) of [***] of the Orders. "Average Percent Received by Lead
Time" shall mean the required percentage of Material (based in units) delivered
within the applicable lead time for such Material, which percentage will be
calculated monthly. "Average Percent Received to Required Date (Past and
Current)" shall mean the required percentage of Material (based in units)
delivered on the date such Material was requested to be delivered by the
Company, which percentage shall be calculated monthly.

                  Supplier is expected to make every effort to deliver Material
in accordance with Company's required delivery schedule as contained in
Company's Orders, and as the delivery schedule may be subsequently modified by
Company. Supplier will promptly notify Company of its "Acknowledged Delivery
Schedule", the schedule by which Supplier can deliver Material requested by
Company. Supplier is also expected to communicate to Company any foreseeable

                  In the event Supplier decides that Initially Defective
Material should be replaced, and Supplier has a "Refurbishment Replacement
Program" in place for Material, then Supplier shall ship a new replacement unit
within seven (7) days of receipt of the defective Material. Supplier shall bear
the transportation cost and risk of loss for the return of such Material. If
Supplier does not have a "Refurbishment Replacement Program" currently in place,
and then implements a program, Supplier shall notify Company within thirty (30)
days and extend to Company the seven (7) day replacement provision for Initially
Defective Material. Until Supplier implements the "Refurbishment Replacement
Program", Supplier shall repair Initially Defective Material as set forth above.

                  After the initial thirty (30) day period for Company's return
of defective Material to Supplier, defective Material shall be returned to
Supplier by Company accompanied by the Repair Order, with risk of loss borne and
freight paid by Company. At the option of Supplier, such Material will be
repaired or replaced by Supplier at no cost to Company for in warranty returns.

                  Unless otherwise agreed upon, Supplier shall complete repairs
and ship returned Material to Company within twenty (20) days of receipt of the
defective Material. Supplier shall bear the cost of freight and assume the risk
of loss for shipment to Company of repaired or replaced Material.

                  If Material returned to Supplier for repair as provided for in
this clause is determined to be beyond repair, Supplier shall promptly so notify
Company and, unless otherwise agreed to by Supplier and Company, ship
replacement Material without charge within seven (7) days of receipt of in
warranty Material if Supplier has a "Refurbishment Replacement Program" in place
for Material. If Supplier does not have a "Refurbishment Replacement Program"
currently in place, and then implements a program Supplier shall notify Company
within thirty (30) days and extend to Company the seven (7) day replacement
provision for in warranty Material. Until Supplier implements the "Refurbishment
Replacement Programs, Supplier shall repair Initially Defective Material as set
forth above.

                  Any Material which is repaired, modified, replaced, or
otherwise serviced by Supplier shall be warranted as provided in the clause
WARRANTY for the remainder of the warranty period or ninety (90) days after
Material is shipped to Company, whichever is later (based upon the date repair,
modification, or other service is completed and accepted by Company).

                  A repair and/or replacement report detailing the repairs or
modification to all units returned by Company will be provided on a monthly
basis.

65.      EPIDEMIC CONDITION

                  In the event that during the term of this Agreement and for
one year after the last shipment date of Material hereunder, Company notifies
Supplier (in accordance with the NOTICES clause) that Material shows evidence of
an Epidemic Condition, Supplier shall prepare and propose a "Corrective Action
Plan" (CAP) with respect to such Material within ten (10)

                                       22
<PAGE>   23
working days of such notification, addressing implementation and procedure
milestones for remedying such Epidemic Condition(s). An extension of this
time-frame is permissible upon mutual agreement of the parties.

                  Upon notification of the Epidemic Condition to Supplier,
Company shall have the right to postpone shipments of unshipped Material by
giving written notice of such postponement to Supplier, pending correction of
the Epidemic Condition. Such postponement shall temporarily relieve Supplier of
its shipment liability and Company of its shipment acceptance liability. Should
Supplier not agree to the existence of an Epidemic Condition or should Company
not agree to the Corrective Action Plan, then Company shall have the right to
suspend all or part of its unshipped Orders without liability to Company until
such time as a mutually acceptable solution is reached.

                  An Epidemic Condition, excluding potential safety hazards,
will be considered to exist when one or more of the following conditions occur:

                  1. Failure reports or statistical sampling showing that three
percent (3%) or more of any consecutive one hundred (100) units of Material
delivered to Company or Company's customers are rejected for defective materials
or workmanship; or repair reports indicate nonconformance for the same defect of
five percent (5%) of the installed Material base.

                  2. Reliability plots of relevant data indicate that Material
has actual Mean Time Between Failures (MTBF) of less than eighty (80%) percent
of the MTBF stipulated in Specification for Material. The MTBF parameter of
Material is defined as the total operation or power-on time of any population
under observation ("T"), in hours, divided by the total number of critical
failures ("n") that have occurred during the observed period. A critical failure
is defined as a failure to operate per the requirements of Specification. The
total operating time for a population is the summation of operating time of
individual units in that population. MTBF is expressed as MTBF=T/n. An Epidemic
Condition shall exist when data derived from populations being tracked confirms
the condition with eighty (80%) percent statistical confidence.

                  3. Material Dead on Arrival ("DOA") failures exceed the
Epidemic DOA failure rate which is defined as two percent (2%) of Material
delivered to Company or Company's customer within a one (1) month period.

                  Only major functional visual/mechanical/appearance defects are
considered for determining Epidemic Condition. Material could be either sampled,
or at Company option, one hundred (100%) percent audited at Company warehouses,
factories, or Company's customers' locations. If Material is sampled, the data
must have eighty (80%) percent or better statistical confidence.

                  For the purpose of this Agreement, functional DOA shall not
include Material for which no defect is found and shall be defined as any
Material that during the test, installation or upon its first use fails to
operate as expected or specified. Visual/mechanical/appearance DOA is defined as
any Material containing one or more major defects that would make Material unfit
for use or installation.

                                       23
<PAGE>   24
                  An Epidemic Condition shall not include failure due to
customer misapplication, misuse, abuse, lightning, utilization of parts not
approved by Supplier, or chain failures induced by internally or externally
integrated subassemblies.

                  In the event that Supplier develops a remedy for the defect(s)
that caused the Epidemic Condition and Company agrees in writing that the remedy
is acceptable, Supplier shall:

                  (a) Incorporate the remedy in the affected Material in
accordance with Engineering Change Control procedures or manufacturing
procedures, as applicable, agreed to by the parties.

                  (b) Ship all subsequent Material incorporating the required
modification correcting the defect(s) at no additional charge to Company; and

                  (c) Repair and/or replace at Supplier's option Material that
caused the Epidemic Condition. In the event that Company incurs costs due to
such repair and/or replacement, including but not limited to labor and shipping
costs, Supplier shall reimburse Company for such costs, as mutually determined
and agreed upon by both parties. Supplier shall bear such risk of in transit
loss and damage for such repaired and/or replaced Material shipped to Company.

                  Supplier and Company shall mutually agree in writing as to the
remedy's implementation schedule. Supplier agrees to utilize its best efforts to
implement in accordance with agreed-upon schedule.

                  In the event that Supplier is unable to develop a mutually
agreeable remedy, or does not adequately take into account the business
interests of Company, as reasonably agreed by the parties, Company may (1)
develop such remedy and implementation cost and risk of in transit loss and
damage shall be allocated between the parties as set forth in this clause,
and/or (2) cancel postponed Orders without liability and return all confirmed
Material affected by such Epidemic Condition for full refund, payable by
Supplier within thirty (30) days after receipt of returned Material (with risk
of loss of in transit damage borne by Supplier) and Company shall have the right
to adjust the Volume/Price levels set forth in the Volume/Price Letter to
reflect the dollar amount being canceled, and/or (3) terminate this Agreement
without further liability.

66.      TITLE TO PARTS FURNISHED BY COMPANY

                  All parts furnished by Company shall remain Company's property
and be kept segregated and marked PROPERTY OF LUCENT TECHNOLOGIES INC. Supplier

Supplier's possession or under Supplier's control. Company may inspect,
inventory, and authenticate the amount of parts that are furnished under this
Agreement during Supplier's normal business hours. Supplier shall provide
Company access to the premises wherein all such parts are located. Supplier
shall at Company's option, return to Company or hold for Company's disposition
any and all of such parts and any scrap produced remaining in Supplier's
possession upon termination of this Agreement.

                                       24
<PAGE>   25
                  Supplier will not assert or file common law or statutory lien
against parts furnished by Company, and hereby waives any such common law and
statutory liens. Supplier shall, within ten (10) days of receipt of Company's
parts, notify Company in writing of any claims for quantity variation in the
parts furnished to Supplier.

                  Supplier shall store Company parts in protected areas approved

                             MATERIAL ON CONSIGNMENT



                  The terms set forth herein (the "Consignment Arrangement")
will govern any Material on Consignment ("Consigned Material") at a Company
location, each as mutually agreed upon by Company and Supplier and as set forth
in Schedule(s) in the form attached hereto.

                  1. TERM OF CONSIGNMENT ARRANGEMENT - The term of the
Consignment Arrangement shall be specified in the acknowledged Consignment
Purchase Order.

                  2. FOB - Consignment site.

                  3. MATERIAL MANAGEMENT - Supplier shall ship all Consigned
Material via any nationally recognized carrier selected by Company and Supplier.

                  At the beginning of each 12 month period of this Consignment
Arrangement or otherwise agreed to by Company and Supplier, Company shall issue
to Supplier a "Master Purchase Order" for each Consigned Material. The Master
Purchase Order shall contain Company's twelve (12) month good faith estimated
annual usage for each Consigned Material. The estimated annual usage will be
provided by the Company solely for administrative purpose and shall not
constitute a commitment by the Company to purchase from Supplier the amount set
forth in the estimated annual usage.

                  Each week the Company shall send to Supplier a Forecast (the
"Weekly Consignment Forecast") for each Consigned Material. The Weekly
Consignment Forecast shall contain an updated twelve (12) month forecast,
including the Company's good faith weekly estimated requirements for a minimum
of the next 26 weeks, for each Consigned Material. Such Forecast shall be issued
by the Company solely for Supplier's Material planning purposes and shall not
constitute a commitment by the Company to purchase from Supplier the amount of
Material set forth in such Weekly Consignment Forecast. The Weekly Consignment
Forecast may differ from the Master Purchase Order estimated annual usage. In
addition, the Weekly Consignment Forecast shall (a) show the quantities
delivered by Supplier that are currently in Consigned Material storage (as
hereinafter defined) and (b) list by part number the amount of Material
withdrawn by Company from Consigned Material storage during such week and the
balance of such Consigned Material Storage. Supplier shall invoice Company each
month for Consigned Material withdrawn by Company in the previous month.

                  Supplier shall review the Weekly Consignment Forecast and
shall adjust Consigned Material Storage Stock support levels and Supplier's work
in process as set forth herein for the mutually agreed to quantities. Supplier
shall manufacture and ship enough Material into Consigned Material Storage so
that Consigned Material Storage contains the following: one (1) week forecast
plus a level of safety stock not to exceed the next three (3) weeks of Company's
forecast for such part numbers based on the then current Weekly Consignment
Forecast.

                                      B-1
<PAGE>   31
                  Supplier shall have the Material Management (which shall be
based upon the Weekly Consignment Forecast) responsibility for Company's
Consignment Site for the Consigned Material. Supplier shall be responsible for
notifying Company of inventory fluctuations considered to be excessive by
Supplier. If upside fluctuations are deemed excessive by Supplier, Supplier and
Company shall work together on a delivery plan mutually agreeable to both
parties.

                  Company's commitment to purchase Consigned Material shall be
only those quantities withdrawn by Company from Consigned Material Storage and
as set forth below. Returns to Consigned Material Storage must be with the prior
written approval of Supplier.


                  If at any time during the twelve (12) month period covered by
a Master Purchase Order, this Consignment Arrangement is terminated by either
party as set forth below, or if Company changes its Weekly Consignment Forecast
to eliminate or materially reduce the quantities forecasted under the Master
Purchase Order, or if this Consignment Arrangement expires and is not renewed
during the term of this Agreement, Company's liability to Supplier shall be to
purchase the sum of the first four (4) weeks of gross forecasted amounts for
such terminated, eliminated or materially reduced or expired items (as
forecasted in the previous week's Weekly Consignment Forecast) and Supplier's
work in process and/or raw materials and components. Company's liability for
work in process and/or raw materials and components should not exceed the
Supplier's Lead Time referenced on Exhibit A of gross forecasted amounts for
such terminated, eliminated or materially reduced or expired items (as
forecasted in the previous week's Weekly Consignment Forecast), Such total of
gross forecasted amounts shall be referred to in this clauses as "Forecasted
Material". For that portion of the Forecasted Material at Supplier's location,
Company's obligation under this subsection shall be limited to the sum of (a)
[***] and (b) [***], (i) [***] and (ii) [***] other customers in the ordinary
course of business over a reasonable period of time); [***] set forth in
(a) and (b) above. If requested by the Company, Supplier agrees to substantiate
such costs and purchase Price with proof reasonable satisfactory to Company.


                  Upon such termination, elimination, material reduction or
expiration the parties shall meet promptly to determine the finished Materials,
work in process, components and raw materials for which Company is responsible
as set forth above. Supplier shall, at Company's option and expense, ship to
Company or scrap such finished Materials, work in process and raw materials and
components for which Company is liable under this clause.

                  4. MATERIAL ON CONSIGNMENT - Supplier shall deliver the
Consigned Material as set forth below:

                           a. Contact Person - The Company's contact person for
each Consignment Arrangement shall be set forth in Company's Weekly Consignment
Forecast.

                           b. Consigned Material Storage - Upon receipt of each
shipment of Consigned Material, Company shall cause it to be placed in

ownership and in such a way that the Consigned Material may be readily
distinguished from other inventory by physical inspection. Supplier may
physically inspect Consigned Material in Consigned Material Storage at mutually
agreeable times during normal business hours. After such inspection, Supplier
may invoice Company for any unaccounted for inventory of Consigned Material at
the Price then in effect under this Agreement.

                           c. Title and Risk of Loss - Upon receipt of
Consignment Material, risk of loss of such lot shall pass to Company. Upon
withdrawal of any item in such lot by Company from Consigned Material Storage,
title to such item shall pass to Company and sale of that lot shall be deemed to
occur.

                           d. Terms of Payment - Net 30 days.

                           e. Withdrawal from Consigned Material Storage -
Company may withdraw or cause to be withdrawn Consigned Material from Consigned
Material Storage at any time. Company shall keep or cause to be kept records and

<PAGE>   13
         unforeseen development, or contingency beyond the control of such
         party, the rights and obligations of such party shall be governed by
         this provision.

         For the purpose of this Agreement, an event, an unforeseen development,
         or contingency beyond the control of the party shall include, but shall
         not be limited to, the following: war, declared or undeclared,

         Each party shall be excused from any failure to perform any obligation,
         except for the payment of uncontested invoices by Tech Data, hereunder
         to the extent such failure is caused by the foregoing causes. Any
         suspension of the performance by reason of this provision shall be
         limited to the period during which the cause or the related effect of
         failure exists, and such suspension shall not affect the running of the
         time period provided for in this Agreement.

                  (a) A party whose performance is prevented, restricted or
                  interfered with by reason of a Force Majeure condition shall
                  be excused from such performance to the extent of such Force
                  Majeure condition so long as such party provides the other
                  party with prompt written notice describing the Force Majeure
                  condition immediately continues performance whenever and to
                  the extent such causes are removed.

                  (b) If, due to a Force Majeure condition, the scheduled time
                  of delivery or performance is or will be delayed for more than
                  ninety (90) days after the scheduled date, the party not
                  relying upon the Force Majeure condition may terminate,
                  without liability to the other party, any Purchase Order or
                  portion thereof covering the delayed Products.

7.9      Return Material Authorization Numbers. In the event any provision of
         this Agreement call/allow for Tech Data to return Product to AT&T
         PARADYNE as described here, Tech Data will obtain an Return Equipment
         Authorization (REA) number from AT&T which will be issued within five
         (5) working days of Tech Data's request; however, if the REA is not
         received within five (5) business days, AT&T PARADYNE shall accept
         returned Products absent an REA. The net purchase price, minus any
         adjustments of such Products returned to AT&T PARADYNE shall be
         credited to Tech Data's account.

         any other agreement between Tech Data and AT&T PARADYNE require that
         AT&T PARADYNE grant credits to Tech Data's account, and such credits
         are not received within thirty (30) days then, all such credits shall
         become effective immediately upon notice to AT&T PARADYNE. In such
         event, Tech Data shall be entitled to deduct any such credits from the
         red monies owed to AT&T PARADYNE. In the event credits exceed any
         balances owed by Tech Data to AT&T PARADYNE, then AT&T PARADYNE shall
         upon receipt of Tech Data's request accompanied by valid supporting
         documentation from Tech Data,

         pay Tech Data the amount of such credit within thirty (30) days of
         AT&T's receipt of such request.

7.11     Severability. If, but only to the extent that, any provision of this
         Agreement is declared or found to be illegal, unenforceable or void,
         then both parties shall be relieved of all obligations arising under
         such provision, it being the intent and agreement of the parties that

         the extent necessary to make it legal and enforceable while preserving
         its intent.

7.12     Waiver. A waiver by either of the parties of any covenants, conditions
         or agreements to be performed by the other or any breach thereof shall

         any other covenant, condition or agreement herein contained.

7.13     Remedies. All remedies set forth in this Agreement shall be cumulative
         and in addition to and not in lieu of any other remedies available to

         reason shall not release either party from any liabilities or
         obligations set forth in this Agreement which (i) the parties have

         competing Products.

         Agreement. Provided, however, AT&T PARADYNE shall provide Tech Data
         with copies of appropriate software and documentation, at no charge,
         for the purpose of effectively demonstrating equipment to Customers.

         AT&T PARADYNE and Tech Data and/or the respective subsidiaries, agents,
         distributors or subsidiaries authorized to conduct business in such
         countries or to negotiate further terms and conditions to provide for
         such right. The parties intend that any further agreements or terms and
         conditions will be consistent with and based upon the applicable terms
         and conditions of this Agreement, subject, however, to requirements of
         local law and local business practice. All Products obtained pursuant
         to this Section shall be deemed for purposes of calculating accumulated
         purchases and any discounts set forth in this Agreement, to have been
         obtained pursuant to this Agreement.

02.3.    MARKET RIGHTS

02.3.1.  WORLDWIDE MARKET RIGHTS

         Both Seller and Buyer intend that Buyer and the Buyer's distributors
shall be a primary distribution channel for the Products to end-user customers
for both the domestic and international markets. The Buyer shall have worldwide
distribution rights to sell the Products.

         Seller shall assist Buyer in obtaining type approvals and homologation
for Buyer to distribute Products worldwide. Homologation schedules and
distribution of homologation costs are to be mutually agreed upon between the
Buyer and Seller. Seller further agrees where applicable to list Buyer's OEM
name on certificates already earned, where possible.

         With respect to non domestic market rights Seller and Buyer agree to
the following:



                  a. On ore before the effective date of this Agreement, Buyer
         will provide to Seller a confidential list (Buyer's list) of those
         countries in which Buyer will support sales of the Products through
         Buyer's direct sales operations or its in-country distributors. The
         Buyer's list will also indicate the names of the distributors that
         Buyer intends to use for resale of the Products in each country. Seller
         will review the Buyer's list and within ten (10) days after receipt of
         such list: i.) Seller shall provide to the Buyer a list (Seller's list)
         that specifies any areas of potential conflicts or problems with the
         Buyer's list and will specify the names of the distributors within the
         countries on the Buyer's list that the Seller is currently in
         negotiation with, ii.) Seller further agrees that it will not enter
         into any new discussions to add other in-country distributors to the
         countries on the Buyer's list for at least six (6) months after the
         Effective Date without Buyer's written consent. After Seller has
         received Buyer's list and returned to the Buyer the Seller's list, the
         Buyer agrees to grant Seller forty five (45) day in which to close on
         any distribution agreements that the Seller may have in process.

                  b. Any time within one year after the Effective Date Buyer may
         add countries to the Buyer's list as Buyer requires. The same
         guidelines as outlined in item a. of this Section will be used for each
         country, with the six month time period starting after Seller receives
         Buyer's written request to add the countries to the Buyer's list.

                  c. Beginning one year after the Effective Date any new
         countries added to the Buyer's list, per item a. and b. above, will be
         subject to a four month rather than a six month window.

                  d. Buyer and Seller agree to review at least semi-annually
         Buyer's sales performance in each country where it is selling the
         Products. If minimal performance objectives are not being met in any
         country, Buyer and Seller will implement mutually agreeable programs to
         improve sales performance in those countries.


                                       4.
<PAGE>   5
                  e. Notwithstanding paragraphs a. through d. above, Seller at
         its option may sell directly to carriers and service providers, and
         OEMs who may sell to these carriers and service providers. However,
         Seller agrees to inform Buyer, whenever practical of any opportunity
         for sales of Product in those international countries where Buyer has
         direct sales channels, except when Seller is unable to do so due to
         business conditions including, but not limited to, non-disclosure
         agreements, RFPs directed to Seller, and opportunities brought to
         Seller by its other partners.

         If Buyer wishes to pursue an opportunity brought to Buyer by Seller,
         Buyer will provide to Seller a plan to pursue the opportunity in a time
         frame in accordance with the following applicable situation:

                           1) Pursuit of an opportunity for which there is no
                  pressing deadline from an external entity: Buyer will submit
                  to Seller a plan within 60 days.

                           2) Pursuit of an opportunity which is constrained by
                  a deadline imposed by an external entity. Buyer must submit a
                  plan to Seller within a time period as required to meet
                  Seller's needs. Seller shall make every reasonable effort to
                  maximize the amount of time that the Buyer has to respond.

                           If rejected by the Seller, Seller will inform Buyer
                  of the reasons for rejection within four (4) business days and
                  conversely Buyer has four days to remedy reasons for
                  rejection, if practical. If accepted, Seller will assist Buyer
                  in Buyer's plan to pursue that opportunity. Furthermore,
                  Seller will not pursue direct sales to the identified customer
                  unless such customer indicates that its does not wish to do
                  business with Buyer.

                           In those cases where Buyer has proposed the Product
                  into an account, and that account subsequently contacts Seller
                  directly, Seller will inform Buyer as soon as practicable. In
                  addition, Seller will use all reasonable efforts to maintain
                  sales of Product through Buyer. If the account informs Seller
                  that it does not want to purchase from Buyer, Seller may
                  pursue that business directly. In such cases, Seller will
                  provide compensation to Buyer in the form of a commission on
                  revenue for all Products sold to that customer for a 12 month
                  period. Such commission will be based on the discount that
                  Seller offers to that customer according to the following
                  schedule:

                           All such commission will be in the form of a credit
                  which Buyer may apply up to 50% of the purchase price of any
                  future purchases of Products.

                           In addition, any U.S.-based reseller with which
                  Seller may have an agreement is not precluded from providing
                  Product to any of its international customers.

                  f. Seller agrees to support Buyer's international sales
              efforts for the Products without preferential treatment to other
              resellers.

With respect to domestic (US) market rights and obligations, Buyer and Seller
agree to the following:

                  g. For a period of twelve months from the general availability
              of the Products to the Buyer's customers ("General Availability
              Date"), Seller agrees to limit to twenty (20) the number of
              distributors authorized by Seller to sell its products. These
              distributors can be either stocking or non-stocking distributors
              classified as "VADs" (Distributors) and resellers (exclusive of
              OEMs).

                  h. The limit of twenty (20) distributors in (a) does not apply
              to OEMs, telcos, Inter-Exchange Carrier's or other providers or
              resellers of telecommunications services. It also does not apply
              to wholesale distributors which primarily sell to such
              telecommunications service providers. For a period of twelve
              months from General Availability Date, such wholesale distributors
              shall be limited to four (4) and shall be reviewed with Buyer.
              Specific wholesale distributors may change from time to time,
              although the number shall be limited to four.

                  i. If Buyer wishes to pursue an opportunity brought to Buyer
              by Seller, Buyer will provide to Seller a plan to pursue the
              opportunity in a time frame in accordance with the following
              applicable situation:

                      1) Pursuit of an opportunity for which there is no
                  pressing deadline from an external entity: Buyer will submit
                  to Seller a plan within 60 days.

                      2) Pursuit of an opportunity which is constrained y a
                  deadline imposed by an external entity: Buyer must submit a
                  plan to Seller within a time period as required to meet
                  Seller's needs. Seller shall make every reasonable effort to
                  maximize the amount of time that the Buyer has to respond. If
                  rejected by the Seller, Seller will inform Buyer of the
                  reasons for rejection within four (4) business days and
                  conversely Buyer has four (4) days to respond, if practicable.

                  j. Seller agrees to review Seller's present distributors and
              future distributors before authorizing distribution or sale of its
              Products with the Buyer in order to minimize sales channel
              conflict and sales expense for both parties. The intent of these

              reviews is to assure Seller that its desired market coverage is
              being met and to assure Buyer that its sales penetration is
              maximized.

                  k. Seller agrees to maintain a minimum differential of 19%,
              referenced to Seller's published list price, between the most
              favorable VAD or Distributor (not OEM's) contract pricing and that
              of the Buyer. In the event of an exception to this for specific
              distributor sales opportunities, the Seller shall notify the Buyer
              and gain the Buyer's agreement as to the special pricing for that
              opportunity.

                  l. In those cases where Buyer has proposed the Product into an
              account, and that account subsequently contacts Seller directly,
              Seller will inform Buyer as soon as practicable. In addition,
              Seller will use all reasonable efforts to maintain sales of
              Product through Buyer. If the account informs Seller that it will
              not purchase from Buyer, Buyer shall inform Seller and Seller with
              Buyer's approval may pursue that business directly. In such cases,
              Seller will provide compensation to Buyer in the form of a
              commission on net revenue on all Product sold to that customer for
              a 12 month period. Such commission will be based on the discount
              that Seller offers to that customer according to the following
              schedule:

Seller's delay in delivery of production quantities of the products ordered in
conformity with this Agreement.

03.5.         RELEASE RESCHEDULE BY SELLER

              At no time can the Seller reschedule any of the Buyer's Releases

party, the parties agree to share in these benefits. Information regarding the
savings or cost reductions will be shared between the parties. Resulting savings
will be allocated between the parties semi-annually on a [***] percent ([***]%)
- - [***] percent ([***]%) basis. The party responsible for implementing the
saving will receive [***] percent ([***]%), and the other party will receive
[***] percent ([***]%) of the resulting saving.

              Prices are exclusive of all sales, use, property, and the like
taxes. Any such tax Seller may be required to collect or pay upon the sale or
delivery of the Product shall be paid or collected by the Buyer and such sums
shall be promptly due and payable to Seller by Buyer under the payment terms of
the Agreement; however, Seller agrees to accept valid tax exemption documents in
lieu of payment where applicable.

04.1.         TERMS OF PAYMENT

be borne by Buyer.

04.3.         CASH ADVANCE

              Buyer agrees to provide Seller certain cash advances in accordance
with Exhibit G. The amounts reflected in Exhibit G represent the parties' best

                                      12.
<PAGE>   13
acceptance, use of or payment for all or any such Product shall be deemed not to
constitute a waiver of any warranty or of any term or condition hereof.

05.2.         BREACH

              In the event of a breach of warranty, Buyer shall provide Seller
with the opportunity to inspect and test product claimed to be defective on
Buyer's premises, or if Seller deems it necessary, at Seller's factory.
Corrective action required on the part of Seller is contingent upon Seller's
examination disclosing that claimed defects have not been caused by misuse,
abuse, neglect, unauthorized alteration or modification, improper installation
or mishandling. The liability of Seller is limited, at the option of Seller, to
either (1) repair of the defective Product or (2) the replacement by Seller at
its cost of the defective Product, or (3) refund of the purchase price of the
defective Product, in the event that the previously stated remedies are not
reasonably available. Whenever the preceding remedies are not practicable, Buyer
may, at its option, remedy any defect in the Product using available parts and
other resources to accomplish such repair or replacement. Buyer's actions under
such condition will be considered to be "authorized" by Seller so that warranty
and the correction of further deficiencies will not be affected. Unless
otherwise agreed to in writing, Seller will bear all costs associated with
correction of the Product, including Buyer's labor, incurred to identify,
remove, package, ship, reinstall and test the replacement for the defective
Product up to a maximum of two (2) times the Buyer's total purchase price of the
defective Product. All transportation and insurance costs, whether incurred by
Buyer or Seller are Seller's responsibility. In the event that Seller can
demonstrate to Buyer's satisfaction that Buyer's claim of breach of warranty is
invalid, e.g., the claimed defect cannot be duplicated or was caused by Buyer's
actions (except as provided above), or that the Product was incorrectly
diagnosed as defective by Buyer, then the above remedies do not apply to the
respective Product which Buyer claimed to be defective. Other remedies and
obligations pertaining to other equipment/Product are unaffected.

05.3.         WARRANTY RESPONSE TIME

              Buyer, if practicable, shall use its spare parts inventory to
effect immediate replacement of the defective item(s) and return the defective
item(s) to Seller for repair/replacement. Seller will effect the
repair/replacement and return the item(s) to Buyer within fifteen (15) days
after receipt of the defective item(s); however, Seller will respond to
emergency situations by immediately shipping Product on hand within twenty four
(24) hours.

05.4.         WARRANTY LIMITATION

              THE ABOVE WARRANTIES COVERING THE PRODUCTS DO NOT INCLUDE AND
SELLER DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE. THE PROVISIONS OF THIS CONTRACT ARE SELLER'S SOLE OBLIGATIONS, AND
BUYER'S EXCLUSIVE REMEDIES, FOR BREACH OF ANY WARRANTY, EXCEPT FOR THE
PROVISIONS OF THE PARAGRAPH ENTITLED "EPIDEMIC". UNDER NO CIRCUMSTANCES SHALL
SELLER BE LIABLE IN ANY WAY TO BUYER FOR INDIRECT, SPECIAL OR CONSEQUENTIAL
DAMAGES, INCLUDING BUT NOT LIMITED TO, ANY LOSS OF BUSINESS OR PROFITS,


                                      13.

WHETHER OR NOT FORESEEABLE AND WHETHER OR NOT BASED ON BREACH OF WARRANTY, IN
CONNECTION WITH THE SALE OF PRODUCTS.

05.5.         WARRANTY EXCLUSIVITY

              The warranties of Seller contained herein extend solely to Buyer
and shall only be enforceable by Buyer. Seller makes no warranty to any persons
other than Buyer.

06.0.         QUALITY ASSURANCE

              Notwithstanding the post-acceptance obligations of Seller, Buyer
has a significant interest in the quality of the Product. Because the Product
has a useful life expectancy greater than the warranty obligation period and
because of the goodwill lost by malfunctioning Products even though they may be
corrected at Seller's expense, it is agreed by Buyer and Seller that without
limiting or abridging Buyer's rights to inspect the Product prior to acceptance
or Seller's post-acceptance obligations, the following provisions shall apply to
ensure acceptable quality for Products manufactured for Buyer under the terms of
this Agreement:

06.1.         QUALITY CONTROL MONITORING

              At any and all reasonable times during the term of this Agreement,
provided Buyer has notified Seller at least two (2) days in advance, Buyer's
representatives shall have access to Seller's facilities to monitor its quality
control system.

06.2.         QUALITY CONTROL MAINTENANCE

              Seller shall maintain the quality control system mutually agreed
upon at the Effective Date and as specified in the Specifications. Changes to
such documents must be submitted to Buyer.

06.3.         ACCEPTANCE TESTS

              Acceptance test procedures for final manufacturing testing are as
set forth in Exhibit E of this contract.

06.4.         SOURCE INSPECTION

              All Products shall be subject to inspection and test by Buyer at
Seller's facility if Buyer so desires. Buyer may, at its option, implement a
sampling inspection with lot rejection in accordance with an appropriate
sampling plan and inspection procedure to be accomplished at Seller's facility.
If any inspection or test is made on Seller's premises, Seller shall, without
additional charge, provide all reasonable facilities and assistance for the
safety and convenience of Buyer's inspector subject to the security and safety
regulations existing at the facilities.

06.5.         WORKMANSHIP STANDARDS


                                      14.
<PAGE>   15

06.7.         SELLER/BUYER CONTINUOUS IMPROVEMENT EFFORTS

              Buyer and Seller mutually agree to develop continuous improvement
task teams in an effort to reduce costs in both processes and Products that will
mutually benefit both parties in the areas of:

              a.  Target Costs
              b.  Cost Reduction Efforts, including both materials and processes
              c.  On Time Shipments as measured by Customer Request Date and
Scheduled Ship Date.
              d.  Repair Data, including DOA's, Infant mortality and Root Cause
Analysis.
              e. Cycle Time Reductions, including Manufacturing, Repair, Release
Processing Spare Parts Delivery and Others.
              f.  Electronic Data Interchange (EDI).

07.0.         INSPECTION

07.1.         INSPECTION AT DESIGNATED DELIVERY LOCATION

              Within thirty (30) days of the receipt of any Product at its
designated delivery location, Buyer may submit such Product to the criteria as
set forth in the Specification, Section 4.2, entitled "Acceptance Testing",
attached hereto and made a part of this Agreement. Buyer shall be entitled to
reject any product that fails to conform to the Purchase Specifications. Notice
of any such rejection shall be issued within five (5) business days by Buyer to
Seller.

              Upon rejection, Buyer will notify Seller of such rejection and
cause for rejection and return the entire shipment or any portion, to Seller.
Seller accepts all cost of rejected lots, including but not limited to shipping
charges back to Buyer, any insurance costs, and all risk of loss (F.O.B.
Destination) for rejected Products. If Seller does not receive such notice of
any such rejection from Buyer within thirty (30) calendar days after shipment of
Product, such Product shall be deemed accepted by Buyer for purposes of this
Section 7. Any Products returned under this Section 7 will be shipped by a
carrier selected by Seller, or Seller will be liable for freight charges at a
rate equivalent to Buyer's documented freight rates. If it is determined that
any Products returned by Buyer under this Section 7 are conforming to the
Specification then (i) Seller shall utilize such Products for Buyer's releases
and Buyer shall, notwithstanding anything to the contrary in this Section 7, pay
for the expenses associated with Buyer's original return of such Products to
Seller under this Section 7.


                                      15.
<PAGE>   16
              Notwithstanding the foregoing, damage to Products caused by
Buyer's Shipper shall not be considered a nonconformity to the Specification.

07.2.         INSPECTION AT SELLER'S LOCATION

              Buyer may, at its option, inspect the Product at Seller's facility
prior to shipment. Buyer's inspection shall be done by its designated
representative (hereinafter referred to as "Representative") who will be
permitted by Seller to witness the Acceptance Test of Product purchased by Buyer
hereunder. In the event that the Representative ascertains that an item of
Product is defective, said Representative will advise Seller's authorized
personnel and such defect shall be remedied prior to shipment. Rejected lots (or
Products) will then be corrected and re-submitted for re-inspection at Seller's
expense. All Products shall be subject to inspection and test by Buyer at
Seller's facility if Buyer so desires. Buyer may, at its option, implement a
sampling inspection with lot rejection in accordance with an appropriate
sampling plan and inspection procedure to be accomplished at the Seller's
facility. If any inspection or test is made on Seller's premises, Seller shall
without additional charge, provide all reasonable facilities and assistance for
the safety and convenience of Buyer's inspectors subject to the security and
safety regulations existing at the facility. Seller shall take the
responsibility to coordinate all source inspection schedules to allow Seller to
meet the Scheduled Ship Dates committed by Seller to Buyer.

07.3.         QUALITY LEVEL REQUIREMENTS

              Seller shall maintain the quality levels specified in the
Specifications. Seller shall be responsible for any and all reasonable
inspection costs resulting from Seller being disqualified from the surveillance
plan as set forth in the Specifications after the first six (6) months from the
initial shipment of the Products under this Agreement. The first six (6) months
will be the quality history and data collection period.

07.4.         FIRST INSTALL SUPPORT

              Seller will provide, at Buyer's request, at locations selected by
Buyer and at no cost to Buyer, technically competent personnel and any
necessary spare parts to assist in the identification and resolution of any
performance problems which jeopardize the progress of the first four (4)
installations of the Product in the continental United States. Seller will also
provide, at Buyer's request, any performance information available which could
assist Buyer in an evaluation of Product performance.

08.0.         SELLER'S LEGAL AUTHORITY

              Seller represents and warrants that it presently has and will
retain the unencumbered legal authority to convey to Buyer the title, rights
and licenses to the Products, and that the performance by Seller of its
obligations hereunder is not and will not be in violation of the rights of any
third party. The foregoing representation and warranty does not apply to the
infringement by the Products of proprietary rights, for which Section 16.7.
below sets forth the exclusive remedy.

09.0.         COMPLIANCE TO STANDARDS

09.1.         SELLER'S CERTIFICATION REQUIREMENTS

              Seller agrees, at its expense and a mutually agreeable schedule,

the shipment of any Products requiring such approvals. If Seller cannot meet
his requirement, Seller shall so advise Buyer in writing. Buyer, at its option,
may grant limited waivers to receive such non-compliant Product. Seller agrees
to assure that all Product shipment made to countries outside of the
Continental United States will be certified and approved to the appropriate
levels as required by said countries. All cable purchased under this Agreement
must meet the applicable UL and CSA requirements.

09.2.         BUYERS CERTIFICATION REQUIREMENTS

10.1.         PRODUCT CHANGES BY BUYER

              In the event that a change to the Specifications or a modification
to the Products is requested by Buyer:


                                      16.
<PAGE>   17
              a. Buyer shall advise Seller of the requested change.

              b. Seller, after reviewing the requested change, shall within the
time periods specified in Section 7.0 of the Specification advise Buyer of the
costs and length of time to effect such change. The lead time into production
and the per unit price change, if any. Seller shall not implement such change
without Buyer's prior written consent. Seller is under no obligation to make any
changes requested by Buyer without Seller's agreement.

              Seller shall not implement such change without producing required
engineering change requests in accordance with Section 7.0 of the
Specifications.

              In the event Seller's quote time to effect the requested change
and the lead time into production is not acceptable to Buyer based on Buyer's
good faith analysis of its market requirements, Buyer will so notify Seller. At
Buyer's request, the parties will negotiate in good faith a mutually acceptable
development and production schedule and Seller will provide Buyer a revised
non-reimbursable engineering ("NRE") cost and per unit price change estimate
within sixty (60) days of such request. Buyer will then have thirty (30) days to
elect to have Seller implement such modification at Buyer's expense. In the
event Seller wishes to provide the modification to its third party customers,
Seller and Buyer will negotiate, prior to delivery of the modification to any
such customer, a reasonable schedule for reimbursing Buyer for its payments of
NRE costs.

              If Seller is unwilling or unable to undertake the requested
modification project, it will promptly inform Buyer, and Buyer will have the
option, exercisable within sixty (60) days of Seller's notification, to
undertake the modification project itself. If Buyer exercises such option,
Seller will promptly provide Buyer such Manufacturing Information reasonably
required to product a Modified Product (as defined below), and will grant Buyer
a non-exclusive, non-transferable license (i) to use, copy and modify the
applicable Manufacturing Information to product the Modified Product, and (ii)
subject to agreement on appropriate license and/or royalty fees to be paid to
Seller (to be negotiated in good faith by the parties), to use and distribute
the Modified Product Developed by Buyer in accordance with the terms of this
Agreement.

              Notwithstanding the foregoing, the obligations of Seller under the
preceding paragraph are conditional upon Buyer's ability to secure such
manufacturing licenses or other proprietary rights of third parties, if any, as
may be required to undertake any modifications or produce or distribute Modified
Products. Seller agrees to provide reasonable assistance to Buyer to secure such
rights. Moreover, Seller's obligations under this Section shall not apply to any
requested modification to the extent Seller's compliance with the provisions of
this Section would breach Seller's obligations to a third party.

              For the purposes of this Section, "Modified Product" shall mean a
Product (such as a voice card, WAN card or other separately identified product)
which is the subject of the modification and in which the modification is
incorporated.

10.2.         NEW PRODUCT DEVELOPED BY SELLER


                                      17.
<PAGE>   18
              If Seller develops a New Product, Seller shall notify Buyer in
writing at least thirty (30) days prior to the time of the initial public
announcement of such New Product, unless other terms are mutually agreed upon,
in advance and in writing, by the parties. At the time of such written notice,
Seller shall also provide to Buyer the available specifications, description,
and technical data necessary to evaluate the New Product. Further, Seller shall
notify Buyer when a working model of the New Product is available for an
engineering evaluation. Buyer reserves the right to replace an existing Product
with the New Product for all future Releases at the time the New Product is
offered commercially and at a price which is mutually agreeable.

              Seller shall not change the Specifications or make any engineering
changes to the Products affecting form, fit, function, backward compatibility,
or spare parts without Buyer's prior written approval. Buyer will approve or
disapprove any such change within the time periods as specified in Section 7.0
of the Specification. If the Buyer's disapproval is not given within such time
periods of receipt of such notice, Seller shall be authorized to make the
necessary change, unless otherwise mutually agreed to by the parties. However,
Seller may change the Specifications or Products without Buyer's prior written
approval if such changes are for reasons of Product safety, certification
compliance or to avoid or eliminate any actual or alleged infringement or
potential infringement by the Product of any patent or copyright. Seller will
provide Buyer all necessary documentation concerning any change by Seller, as
outlined in Section 7.0 of the Specification, at least 30 days prior to the
first shipment of changed Product.

10.4.         PRODUCT DISCONTINUANCE

              Seller agrees to notify Buyer at least fifteen (15) months prior
to the discontinuance of any Products listed in Exhibit A of this Agreement
provided Buyer agrees to reasonably cooperate with Seller to shorten this notice
period. New Products that are introduced to replace a discontinued Product will
be functionally equivalent or better than the Products being replaced, and the
terms and conditions in section 10.0. of this Agreement related to functional
equivalence will apply to all proposed New Products.

determination of such fee shall be subject to arbitration under Section 16.19.

Buyer will have the right to withdraw the Manufacturing Information contained in

              Notwithstanding the foregoing, the obligations of Seller under the

manufacturing licenses or other proprietary rights of third parties, if any, as
may be required to manufacture such Product. Seller agrees to provide reasonable
assistance to Buyer to secure such rights including the assignment of its rights

              Furthermore Seller will grant to Buyer the license to manufacture

                  2. The Transfer Price shall be the price as stated in Exhibit
                  A, under the heading "AT&T Purchase".

                  3. The Seller's Current Manufacturing Cost shall be that price

<PAGE>   25
                  4. If the Buyer's Manufacturing Costs are less than the
                  current Transfer Price but greater than the Seller's Current
                  Manufacturing Cost then the Buyer will sell the Product to the
                  Seller at the Buyer's Manufacturing Costs, and the Seller will
                  in turn sell the Product back to the Buyer at a price which is
                  the higher of (1) the Transfer Price or (2) one hundred six
                  (106) percent of the Buyer's Manufacturing Costs.

                  5. If the Buyer's Manufacturing Costs are greater than the
                  Seller's Current Manufacturing Cost and is greater than or
                  equal to the Transfer Price then the Buyer will sell the
                  Product to the Seller at the Buyer's Manufacturing Costs, and
                  the Seller will in turn sell the Product back to the Buyer at
                  a price not to exceed one hundred six (106) percent of the
                  Buyer's Manufacturing Cost.

                  6. If the Buyer's Manufacturing Costs are less than or equal
                  to the Seller's Current Manufacturing Cost then the Buyer will
                  sell the Product to the Seller at the Seller's Current
                  Manufacturing Cost, and the Seller will in turn sell the
                  Product back to the Buyer at the Transfer Price.

                  7. Both parties agree to share cost data sufficient to
                  evaluate adherence to the above requirements.

              c. Where the Seller is able to cure the material breach outside of

conditions:

                  1. The Seller must reimburse the Buyer for all customary and
                  reasonable costs incurred in the start up phases of the Buyer

                  2. Seller cannot discontinue the Buyer's right to manufacture
                  until one (1) year has expired after the Buyer has begun
                  manufacture of Products.

14.3          ESCROW

              Seller certifies it will deposit all Manufacturing Information,

negligent acts of Seller, arising out of the performance under this Agreement or
Seller's breach of this Agreement; provided, however, that this obligation shall
not cover any damage to the Products themselves. Buyer agrees that it will
indemnify and hold harmless Seller against and from any and all claims, damages
and liability, including expenses and reasonable attorneys' fees, suffered by

parties, including without limitation Seller's employees, caused by defects in
components supplied by Buyer and incorporated into the Products, or the acts of

any action.

measures to protect Proprietary Information and, without limiting the foregoing,
agrees to exert at least the same effort to prevent disclosure of such
Proprietary Information as it would its' own proprietary information and to not
disclose any part thereof without the Seller's written consent (such consent not
be unreasonably withheld). Notwithstanding any provisions herein concerning
non-disclosure of the Proprietary Information, Buyer shall have no obligations
hereunder for any such information which Buyer can document 1) is already known
to Buyer at the time Seller disclosed such Proprietary Information to Buyer, 2)
is or becomes known to the general public through publications, inspection of
Product or otherwise and through no wrongful act of Buyer, 3) is received from a
third party without that party's breach of disclosure restriction and without
breach of this Agreement, 4) is shown to have been independently developed by
Buyer, 5) is disclosed to a third party by Seller without a similar restriction
on the third party's rights, or 6) is approved for release or use by written
authorization of Seller. The obligations of this section shall survive
termination of this Agreement for a period of two (2) years. Seller retains
exclusively for itself all proprietary rights in and to all designs, engineering
details, and other data pertaining to all Products.

16.7.         PATENT/COPYRIGHT INFRINGEMENT INDEMNIFICATION

              Seller is unaware of any claim, either threatened or impending,
that the Products infringe any patent, trademark or copyright. Seller agrees to
indemnify and hold harmless Buyer from and against all damages, liability and
cost suffered or incurred as a result of any claim that any Products furnished
pursuant to this Agreement constitutes an infringement of any patent, trademark
or copyright provided that Buyer gives Seller reasonable notice of any such
claims. Said indemnification shall extend only to damages assessed against or
costs incurred by Buyer as the result of a judgment rendered by a court of last
resort or a court of lower jurisdiction from which no appeal has been taken
holding that any Product, spare parts and documentation furnished pursuant to
this Agreement constitutes an infringement of any patent, trademark or
copyright, or to any settlement of such claim consented to in writing by Seller.
Buyer shall not be entitled to recover from Seller any loss of profits suffered
by Buyer as a result of such infringement or alleged infringement.

              At the request and expense of Seller, Buyer shall assist and
cooperate with Seller in defending against any such alleged infringement. It is
agreed that Seller shall undertake the sole and complete defense of any such
claim of infringement through counsel of its own choice and at its expense. In
case any Product is held to constitute an infringement in such suit or
proceeding and the use of said Product is enjoined, Seller shall, at its own
expense and option, either (a) procure for Buyer the right to continue using
such Product, (b) modify said Product so as to render it non-infringing, or (c)
accept the return of said Product and refund the purchase price. The provisions
of this Section shall not apply with respect to any claim of patent, trademark,
or copyright infringement based solely on the components added to the Products
by Buyer. Further the provisions of this Section shall not apply if the
infringement arises out of a modification of said Products after delivery by
Seller. The rights granted to Buyer under this section 16.7. are Buyer's sole
and exclusive remedy for any alleged infringement of any proprietary rights of
any kind.

16.8.         INDEPENDENT CONTRACTOR


                                      28.
<PAGE>   29
              It is understood and agreed that nothing stated in the Agreement
shall be construed as creating the relationship of employer and employee or
principal and agent between the parties hereto. Buyer and Seller shall be deemed
independent contractors at all times with respect to their performance and
neither shall have the right or authority to assume or create any obligation,
express or implied, on behalf of the other except as may be otherwise provided
herein. Neither Buyer nor Seller will use any words, perform any act, or make
any statement, written or oral, which would imply or indicate, or tend to imply
or indicate, that it or its business is an agent or representative of the other
party; an agency, division, subsidiary, or branch of the other; or that one, in
any manner, either directly or indirectly, owns, controls, maintains, or
operates the other or its business. Neither party is in any manner responsible
or liable for the other's obligations; nor does any relationship exist between
Seller and Buyer, other than that of independent contractor.

accountants and other professionals connected with the arbitration.

confidential information or violation of its proprietary rights in the Products,
jointly or individually developed products or enhancements thereto, or their
designs.

17.0.         ADDITIONAL AGREEMENTS

              It is the intent of both the Buyer and the Seller to review as
required the need to amend this agreement or to enter into new agreements for
the mutual benefit of the parties.

              Buyer and Seller agree to meet at least every six (6) months to
review market conditions and business opportunities that may require new
agreements to increase sales, market share and/or market position. Such
agreements may include, but are not limited to bi-lateral technology transfer,
joint development of new products, or enhancements to existing Products.


                                      31.
<PAGE>   32
              Should these meeting identify a market opportunity for either
party, Buyer and Seller agree to enter into "Good Faith" negotiations toward an
Agreement that benefits both parties.

18.0.         MANUFACTURING

              Buyer shall have the right to become a primary manufacturing
source for the Seller's Products and New Products, at the Buyer's or any of it
affiliate's manufacturing locations, if it can meet or beat the material terms
and conditions of Seller's then current primary manufacturing source. All bids
shall be fairly reviewed by the Seller for meeting product manufacturing and
quality standards that the Seller would propose to any other sub-contract
manufacture. Seller agrees to share all manufacturing cost data for the Products
with the Buyer and to actively pursue the exchange of the manufacturing
information required for the Buyer to submit such a bid. If the bid to
manufacture the Products is rejected by Seller, Seller will within ten (10) days
of such rejection submit to the Buyer a memorandum detailing the reason why the
bid was rejected.

              If during the term of this Agreement Buyer elects to manufacture
the Products for its customers at its facilities or any affiliated facility,
then Buyer shall have such right provided the transfer price to Seller is no
greater than the aggregate of the costs Seller would have otherwise incurred if
manufacturing had been done by its then existing supplier, assembly was done by
the Seller (including freight, duty, testing, inspection) and any other costs
that Seller would have otherwise incurred.

              For any products or enhanced products jointly developed by the
parties pursuant to Section 17.0., both parties will have the rights to
manufacture and market (such marketing rights subject to limitations contained
in this agreement) such products. If Buyer develops enhanced products it shall
have the right to manufacture and sell such products subject to a reasonable
royalty for any incorporated Seller proprietary technology.

19.0.         SOFTWARE

19.1.         SOFTWARE LICENSE

              Buyer acknowledges and agrees that the Products contain software
and firmware (the "Software") that is not sold to Buyer. Seller hereby grants
Buyer and Buyer's authorized distributors a license to reproduce and distribute
the Software to and sublicense end-users of the Product to use the Software
solely in connection with the Products.

              The Buyer shall sublicense the Software under a license agreement
with the Buyer's end user customer that contains substantially the same
provisions as are contained herein and Buyer will ensure that its distributors
also comply with this requirement.

19.2.         SOFTWARE AVAILABILITY

              All software will be made available to the Buyer in both a hard
coded (firmware EPROM, etc.) and a soft coded copy (diskette, tape, etc.) as
deemed necessary by the Buyer for the particular application.

              Seller agrees to provide Buyer with two (2) master copies of all
requested Software Bug Fixes, Software Maintenance Releases and the associated
documentation at no charge for the term of this Agreement. All Software Feature
Releases will be provided to the Buyer at a cost mutually agreed to by the
parties and in accordance with Section 16.3 of this Agreement. If Software Bug
Fixes are incorporated into the Software Feature Releases and not made available
as a Software Maintenance Release then the Software Feature Release will be
provided, as requested, to the Buyer at no charge.

              All Software Bug Fixes and Software Maintenance Releases will be
made available to the Buyer on the day that it is generally available. All
Software Feature Releases will be available to the Buyer as required by the
Buyer. All technical documentation for a Software Feature Release will be
available to the Buyer in a camera ready state thirty (30) days prior to the
general availability of such release.

19.5.         SOFTWARE SUPPORT

              Seller agrees to provide support services to the Buyer for the
Software in accordance with the support provisions as defined for the Products
of this Agreement. Seller further agrees to coordinate the prioritization of all
Software problems as reported by the Buyer into the follow on releases based
upon the priorities reviewed with the Buyer. The Seller will issue monthly
reports to the Buyer covering status of the Software problems, current time
frames for repair, current development testing and results. Software for which
new versions have been issued will continued to receive support for two (2)
years post issuance of versions by Seller.

              Seller agrees to provide a single point of contact within their
development organizations for consultation, defining unique features,
establishing priorities for unique features, new Software Feature Releases
information, establishing priorities, status and results for Software Bug Fixes.

              Seller agrees to provide support service response times for
Buyer's Software reported problems, proposed changes and Enhancements (also
referred to by Buyer as Modifications Requests (MR)) as specified in the
Specification.

     described in Section 8.0. (All reference to "Section" numbers shall mean
     the Sections of this Specification.) Seller's obligations set forth in
     this Specification shall not diminish Seller's obligations set forth in
     the "Warranty" clause or any other clauses in this Agreement.

     7.2  This Specification does not cover the manufacture of the Products in
     detail but is intended only to define the special arrangements and
     operational requirements in which Buyer is directly interested. All
     aspects not covered by this Specification shall be in accordance with the
     standard practice of Seller.

     7.3  Prior to the first shipment of Products, Seller shall submit to Buyer
     copies of the Documentation in accordance with Section 6.3 and shall have
     received production sample approval from Buyer.

     A production sample of the Products, identical to the proposed production
     units, shall be qualified at Seller's facility for conformity to this
     Specification and Seller's production test requirements as set forth in
     Section 8.9. Prior to qualification, Seller shall submit to the Buyer
     written test procedure which Seller intends to use for the qualification
     program. If the production sample conforms with the requirements of
     Section 6.3 documentation and all other parts of this Specification,
     final approval of the production sample will be granted.

     7.4  Any change proposed to be made by Seller in the PRODUCT (hardware or
     software) furnished in accordance with this Agreement, or in the
     Specification and Documentation covered by this Agreement that would
     impact upon (1) reliability, (2) the requirements of the Specification,
     or (3) form, fit, or function (as defined below) requires advanced written
     notification to and approval by the Buyer in accordance with the following
     procedures.

     in the form of an Engineering Change (EC) will be required except for
     those cases where an extremely unsatisfactory condition requires immediate
     action. In that instance, verbal notification to Buyer shall be used,
     followed by Seller's immediate written confirmation. Such written proposal
     shall be reviewed by the Buyer within the following times from receipt of
     the EC:

          a)   Emergency EC's - one week

          b)   Urgent EC's - two weeks unless otherwise agreed upon in writing
               by Buyer.

               by Buyer.

<PAGE>   51
7.0  GENERAL AND PRODUCT CHANGES (continued)

          7.4.1.  "Form" shall mean changes in appearance visible to the user
                  (customer, repair personnel, developer) of the PRODUCT.

          7.4.2.  "Fit" shall mean changes in parts or components, that are not
                  physically interchangeable.

          7.4.3.  "Function" shall mean changes that affect operational
                  characteristics of the PRODUCT or require the operator to
                  change the method of operation.

     7.5.  Buyer may propose changes or enhancements (collectively "changes") to
     the design of existing PRODUCT covered by this Agreement by submitting a
     Modification Request (MR) to Seller. All MR's require internal Buyer
     approval. Properly approved MR's will be forwarded to the Seller by Buyer's
     responsible Purchasing and Transportation contract Manager.

     7.5.1.  The MR will include details of the suggested changes; including but
     not limited to priority, functional requirements, development work
     statements, physical drawings, etc., and reason for the request.

     7.5.2.  MR's will be generally classified as:

             a)  Emergency: Changes are being requested to correct Severity 1
                 or Class A problems when detected by Buyer.

             b)  Urgent: Changes are being requested to correct Severity 2 or
                 Class AC and AR conditions when detected by Buyer.

             c)  Normal: Changes being requested to enhance PRODUCT features
                 such as Class B, BU and U, or Severity 3 or 4 changes.

     written proposal to Buyer, specifically documenting all cost factors,
     implementation schedules, Documentation changes, test procedure changes,
     service and repair changes associated with the MR. Such written proposal
     shall be furnished to Buyer within the following times from receipt of the
     MR:

            a)  Emergency MR's - one week

            b)  Urgent MR's - two weeks unless otherwise agreed upon in writing
                by Buyer.

            c)  Normal MR's - one month unless otherwise agreed upon in writing
                by Buyer.

     7.5.4.  If Buyer accepts Seller's proposal, the Specification and other
     applicable sections of this Agreement will be amended to reflect the agreed
     upon MR.



<PAGE>   52
7.0   GENERAL AND PRODUCT CHANGES (continued)

      7.6   Any change proposed by Seller or Buyer in hardware shall be
      classified into one of the following six classifications:

      Class A - Corrections

      A.    Changes which are (1) needed to correct (a) inoperative electrical
      or mechanical conditions, or unsatisfactory maintenance or operating
      conditions, (b) conditions which result in safety hazards, or (c)
      conditions which result in non-compliance with federal registration or
      radiation requirements or other federal, state or local safety regulations
      or UL requirements; and (2) judged by Buyer severe enough to have to be
      made to all hardware in process, in stock or installed.

           AC.   Changes in which are (1) needed to correct (a) inoperative
                 electrical or mechanical conditions, or unsatisfactory
                 maintenance or operating conditions or (b) conditions which
                 result in safety hazards where the conditions in (a) or (b) are
                 caused by circuit combinations or options which exist only on
                 certain hardware; (2) needed to compensate for marginal (worse
                 circuit) cases where the inoperative or unsatisfactory
                 conditions exist on certain hardware and cannot be associated
                 with specific circuit combinations or options. Such changes
                 shall be made on Products in process and if requested by Buyer
                 on Products in stock or already installed.

           AR.   Changes which are needed to correct unsatisfactory electrical,
                 mechanical or operating conditions, which may be allowed to
                 exist on a temporary basis. Such changes shall be made to
                 Products in process, except that in some cases, if Buyer gives
                 written consent, Products may be shipped for a period of time
                 specified by Buyer without incorporating the change at that
                 time to Products in process. If Buyer requests that such
                 changes be made to Products in stock or already installed,
                 supplier shall make such changes.

      Class B - Enhancements

           B.    Changes which are sufficiently important to require their
                 application to Products being manufactured (as soon as
                 reasonably possible) and/or which may also be recommended for
                 application to existing stock and installations in the field.
                 Examples of this class of changes may include, but are not
                 limited to:

                 a)   Providing new features that directly affect customer
                      service or operability.
<PAGE>   53

7.0  GENERAL AND PRODUCT CHANGES (continued)

               b)   Providing design improvements which result in better service
                    capabilities, longer life or improved operability margins.

               c)   Providing changes in design which result in important cost
                    savings to Buyer.

          BU.  For conditions of a mandatory nature, for example, the
               fulfillment of future federal registration or future
               compatibility requirement or for conditions of sufficient
               importance to be intended for universal application. Such changes
               would only be required of Products in process.

     Class D - Non-Customer Affecting

          D.   Other changes not sufficiently important to justify application
               to Products being manufactured within any specified time frame
               and not sufficiently important to recommend for application to
               existing stock and installations in the field.

     7.7. Any change proposed by Seller or Buyer in software (firmware,
     operating system or applications software) shall be classified into one of
     the following four classes:

     Severity 1 - Changes needed to correct significant portion(s) of the
                  software which has been identified as unusable, and which use
                  has been suspended pending the resolution of the program
                  error.

     Severity 2 - Changes needed to correct the subsystem portion(s) of the
                  software which has been identified as usable, and which has
                  been suspended pending the resolution of the subsystem error.

     Severity 3 - Changes needed to correct a difficulty in programming or
                  processing difficulty experienced by users and which require
                  inconvenient circumvention to get around the program error.

     Severity 4 - Changes needed to correct a difficulty in programming or
                  processing for which there exists an easy method to avoid the
                  program error.

     7.8.  The format of Seller's notification document required by Section 7.4
     above shall be the responsibility of the Seller but said notification
     document shall contain at least the following information:

          1.   Seller name

          2.   Agreement number

          3.   Products description

           5.   Change number

           6.   Products affected

           7.   Reason for change (reference to the original EC, if applicable)

           8.   Description for Change (including impact upon (1) reliability,
                (2) the requirements of the Specification, and (3) form, fit or
                function)

           9.   Cost impact (including but not limited to costs for field
                modification kits

           10.  Marking and method of identifying changed units

           11.  Documentation: (a) marked up documents and drawings shall be
                provided until the document or drawing is reissued, (b) listing
                of documents and drawings to be changed, and (c) field repair or
                modification kit documentation (if applicable)

           12.  Units in process, in stock and installed affected by change

           13.  Date changes are proposed to be implemented

FREMONT, CALIFORNIA 94538

Agreement number LGSC103DS, dated and signed December 4, 1992 by and between
Premisys Communications Inc. and AT&T Paradyne Corporation is hereby amended as
follows. In the event there are conflicts in the terms of this Amendment and the
OEM Agreement, the terms of the Amendment will apply.

1.0      BASE PRICES

1.1      For Product shipped under this amendment, AT&T PDN will pay Base Prices
         per attachment "B", which will average an additional [***] off the
         current Price List as of January 1, 1995. Such Base Pricing in
         Attachment B will be decreased an additional [***] and an additional
         [***] in 1997.

1.2      The new Base Prices and discounts will become effective on the date the
         contract amendment is signed and will be applied to all unshipped
         orders as well as future orders. Discount levels will reflect date of
         order receipt. In such cases where special pricing has been agreed upon
         between Premisys and AT&T PDN in response to special bids, present or
         future, the discount structure will reflect the lower of the special
         pricing or the discounts under the terms of this amendment.

1.3      Pricing and discounts under this amendment are warranted by Premisys to
         be comparable to or more favorable to AT&T PDN than equivalent prices,
         warranties and terms offered by Premysis to any other customer for the
         term of this amendment.

2.0      DISCOUNT STRUCTURE

2.1.     AT&T PDN will be granted additional price discounts off of the Base
         Price according to the discount tables below.

         a.   Product discounts will depend upon AT&T PDN's shipment volumes and
              will include current Products as listed in the then-current
              Attachment B and any "new" Products which AT&T PDN might choose to
              ship in the future (exclusive of Product(s) which might be
              developed through any joint development efforts). Shipments will
              be valued at the prices actually paid by AT&T PDN during the same
              period.

                                                              AMENDMENT NUMBER 4


         the end-user customer or is in the distribution chain of any sale by
         Premisys' Distributors or OEMs, then Premisys will provide no other
         than standard Product support or pricing in support of such sale.

4.2      In the event that AT&T has the ability to enter international markets
         based on its local manufacturing capabilities or content and where
         Premisys has no current form of distribution, AT&T Paradyne will be
         able to request and, upon agreement of mutually agreed to objectives,
         be granted an exclusive marketing and sales rights in that country.
         Buyer and Seller will establish mutually agreeable performance
         objectives for each country in which it is selling Products and will
         review at least semi-annually Buyer's sales performance in those
         countries. If minimal performance objectives are not being met in any
         country, Buyer and Seller will implement mutually agreeable programs to
         improve sales performance in those countries. In the event that AT&T
         Paradyne does not meet performance objectives agreed upon, such
         exclusive marketing rights will be forfeited. Upon forfeiting such
         exclusive marketing and sales rights, AT&T PDN will immediately be
         granted nonexclusive marketing and sales rights for those same
         countries.

4.3      Except for the provisions of this amendment upon execution of this
         amendment Premisys will not be limited in any fashion in having
         relationships with other companies.

4.4      It is the intent of AT&T PDN to more fully utilize Premisys and their
         partners as a distribution vehicle for products developed and/or
         bundled with other Premisys Products and Technologies. These
         developments may include, but not be limited to CAP and related
         Transmission Products, [MU] Law modem Products and other complementary
         Network Access Products. This relationship will be developed and
         defined under a separate Distribution Agreement.

5.0      JOINT DEVELOPMENT

5.1      AT&T PDN will develop and submit to Premisys a Technology Plan which
         will be updated quarterly. The Technology Plan will include AT&T PDN's
         plans for integrating technologies and features into the Premisys
         Product platform as well as any other plans for joint development
         activities. Such planned technologies and features to be integrated
         will be reasonably achievable and will be in support of AT&T Paradyne's
         then-current Technology Roadmap. Premisys agrees to implement the
         Technology Plan of which an implementation schedule will be mutually
         agreed upon. Such implementation schedule will reflect commercially
         reasonable project start dates and completion dates which will be
         incorporated into a documented project plan and the Premisys Master
         Release Plan. In the event AT&T PDN wishes to undertake additional
         integration or joint development efforts not included in the Technology
         plan, AT&T PDN and Premisys will negotiate such projects in good faith.

5.2      The terms of the current joint Development Agreement LGSC104DS, dated
         September 30, 1993, and as amended from time to time, will remain in
         effect.

6.0      TRAINING AND SUPPORT

         Premisys agrees to provide training and support to AT&T Tier 4 Support
         group. Such training and support will consist of one Tier 4 training
         class as soon as practicable, one Tier four training class by end of
         1995, and one Tier 4 class for each major release. Classes will be held
         at a location of AT&T PDN's choosing and will include all training
         materials. Training and materials will be adequate to ensure that AT&T
         PDN has the ability to be self-sustaining in internal training and Tier
         4 support.

Largo, FL 33773                         Basking Ridge, NJ 07920


Whereas Lucent Technologies, Inc. ("Company") and Paradyne Corporation
("Supplier") entered into a Supply Agreement ("G-18150-E"), as of July 31,
1996 and;

Whereas the Supply Agreement includes reference to a "Volume/Price Letter" also
dated July 31, 1996 that specifies Company's volume purchase requirements and;

Whereas Company and Supplier entered into an "Exclusivity and Amendment
Agreement", dated August 6, 1998, which terminates the "Volume/Price Letter" in
exchange for Company forgiveness of principal on "Core Business Note", and
execution of exclusivity supply relationship;

Now, in consideration of the foregoing recitals, and effective as of August 6,
1998, the following clauses are modified to make G-18150-E consistent with
terms of the Exclusivity and Amendment Agreement. All other terms and
conditions of G-18150-E remain unchanged:

1. TERM
This Agreement shall become effective as of the date here of and shall continue
in effect until June 30, 2001. The amendment or termination of this Agreement
shall not affect the obligations of either party to the other under then
existing Orders issued pursuant to this Agreement, but such Orders shall
continue in effect as though this Agreement had not expired or been terminated
and was still in effect with respect to said Orders.

2. ORDER
For the purpose of this Agreement, an "Order" shall mean Company's form of
purchase order or contract used for the purpose of ordering Material. Each
Order shall reference this Agreement, thereby incorporating in such Order the
terms and conditions stated in this Agreement.

                                                                 Amendment No. 1
                                                                    Page 2 of 14


3. MATERIAL

For the purpose of this Agreement, "Material" shall be defined as those
services performed by Supplier for Company and those Access products that are
identified by Product Family and described on Exhibit A to this Agreement
("Existing Products"): which attachment shall be continuously updated, to
include Enhanced and New Products if such products satisfy the requirements of
the clause ENHANCED AND NEW PRODUCTS.


4. ENHANCED AND NEW PRODUCTS

For the purpose of this Agreement, "Enhanced Product" or "Enhanced Products"
shall mean any product which results out of Company's desire to have Supplier
redesign, modify, or enhance an Existing Product or family of Existing
Products. For the purpose of this Agreement, "New Product" or "New Products"
shall mean product which is not an enhanced Product or Existing Product but
which is substantially similar to an Existing Product with respect to design an
function and possesses reasonable performance improvements. If Company desires
to purchase an Enhanced of New Product(s) from supplier, company shall so
notify Supplier and provide Supplier the opportunity to manufacture such
Enhanced or New Product(s), subject to the following conditions and procedures.

The Company requests for Access Product enhancements and new features or new
products shall be processed through the quarterly Meeting process, or as
needed. The decision to proceed will be based upon a business case that is
positive to both Company and Supplier. Supplier shall, within thirty (30) days
from the date of Supplier's receipt of Company's notice, inform Company whether
Supplier desires to manufacture and supply such Enhanced or New Product(s) to
Company. If Supplier desires to manufacture and supply such Enhanced or New
Product(s), Supplier shall provide Company (a) a written production plan
demonstrating Supplier's ability to satisfy the Performance Requirement, as
described in the next sentence, for such Enhanced or New Product(s) (such plan
shall include production locations and proposed dates for prototypes, sample
production and full production) and (b) Supplier's proposed Price for such
Enhanced or New Product(s). "Performance Requirement" shall mean the Company's
reasonably prescribed performance standards for Material, including, but not
limited to, quality, compliance with Specifications, delivery and service
support, each determined in the case of an Enhanced Product with reference to
standards for an Existing Product or family of Existing Products.

                                                            Agreement: G-18150-E
                                                                 Amendment No. 1
                                                                    Page 3 of 14


The parties shall then negotiate in good faith to reach an agreement on such
production plan's ability to satisfy the Performance Requirements and the Price
to be charged for the Enhanced or New Product(s). In the event the parties
agree on the production plan's satisfaction of the Performance Requirement and
the Price for such Enhanced or New Product(s), and Supplier fulfills its
obligations under the production plan (including the commencement of full
production runs), then such Enhanced or New Product(s) will be added to Exhibit
A for the purposes of this Agreement. Where Company and Supplier have agreed
upon a production plan's satisfaction of Performance Requirements, and price,
and such production plan materially slips without contributing fault of
Company, then Company may procure competitive product from alternative source.
Given these circumstances, and when Supplier is able to satisfy the production
plan, Company agrees to add such Enhanced or New Products to Exhibit A.
However, such action by Company shall not restrict the Company from selling
product from (the above) alternative supplier under a dual source arrangement
provided Supplier's product is carried as the preferred product for resale. All
work performed by Supplier under this clause will be at Supplier's sole risk
and expense, unless otherwise agreed to by the parties.

If despite good faith negotiations the parties fail to agree (i) that the
Enhanced or New Product(s) production plan satisfies the Performance
Requirement or (ii) on a Price for the Enhanced or New Product(s), the parties
agree to resolve the dispute through escalation to Supplier CEO and Company
Purchasing Vice President or designee. In the event that this escalation
process is unable to resolve the dispute, the parties agree to promptly retain
an independent, non-affiliated consultant experienced in the industry to
provide an objective assessment of the issue(s) in dispute. The determination
of the consultant shall be final and binding. If the Supplier desires not to
make available for order by Company any Enhanced or New Product, the Company
may purchase the Enhanced or New Product(s) from another source or sources
without further obligation under Article 8.

7. BEST PRICE


Supplier's Prices to Company, within any given geographic region or country, for
Material contained herein with applicable discounts and with any increases
permitted hereunder, shall be at least as low as those Prices (with applicable
discounts) offered by Supplier within that region or country to any of its other
customers for comparable Material and Services in comparable quantities and
terms. If, within any geographic region or country, Supplier at any time extends
to any other customer lower Prices or higher discounts for comparable quantities
and Material and under comparable terms, Supplier shall promptly notify Company
of such Prices or discounts and grant to Company the benefit of such Price or
discount for all Material sold to Company within that geographic region or
country retroactive to the effective date of Supplier's Price or discount
arrangement with its other customer.

8. MARKET RIGHTS

(a)  Supplier will supply 100% of Company's requirements for access Products
     (as defined in Subsection 8(c)) for resale as "Stand-Alone Products".
     Stand-Alone Products means products that operate individually or as a
     component in a Supplier system. Examples of Stand-Alone Products are the
     Supplier 3160 DSU/CSUs and/or cards that are inserted into a carrier to
     create a system. An example of a product that is not Stand-Alone would be
     a board or component that is to be inserted into another vendor's product
     as an OEM in order to complete a function that the other vendor wishes to
     provide. Company shall not purchase products for resale as Stand-Alone
     Products that are substantially similar in design, functionality, and
     operating characteristics to and compete in the marketplace with those
     Access Products defined in Subsection 8 (c), and as they basically exist
     on the date of this Amendment. With respect to Company's internal
     requirements for Access Products, Supplier shall have Preferred Supplier
     status ("Preferred Supplier") through the same period. Preferred Supplier
     status shall mean, with respect to Company's internal requirements, that
     Supplier shall be given the first opportunity to supply such products.
     Supplier's ability to sell to any customer will not be restricted.
     Supplier will use diligent efforts to meet such requirements, shall be
     free to contract at its discretion with third parties to manufacture
     products of its design or otherwise assist in fulfilling the requirements
     for its Access Products.

(b)  Quarterly relationship meetings will occur with alternating sites between
     Supplier and Company. Attendees shall include decision level making
     representatives of each party. The host company shall assume agenda and
     minute responsibility. Minutes require joint approval or noted objections
     but such minutes should not be construed as binding or enforceable legal
     agreements. Interim working group meetings will continue similar to the
     structure today.

(c)-(1)  Company shall satisfy 100% of its requirements for Access Products for
         resale as "Stand-Alone Products" during the term of this Amendment
         from Supplier for the following core products, their enhancements, and
         their normal evolution within currently defined market segments:

(c)-(iii) Exception Statements --

              1.  APPLICABLE ONLY TO THE SUPPLIER'S ANALOG PRODUCTS OF SECTION
              8(c)(i)-1 -- Company shall not be obligated to purchase 100% of
              its requirements from Supplier unless the products are currently
              embedded in Company designs, drawings, or configurators. Company
              will not proactively encourage current analog customers to replace
              Supplier's analog products with like products from other
              manufacturers. Company shall not be obligated to purchase 100% of
              its requirements from Supplier if customer has called for specific
              vendor's product in an RFP or sale. In those cases where customer
              has called for a specific vendor's product, Company may not make a
              concerted effort to expand marketing dollars, include as part of
              an offer, promote, pay commission or incentives, nor PEC/Com code
              such products for general availability of the other vendor's
              analog products. Company should first attempt to respond with
              Supplier's equipment and revert to another vendor as a last
              resort.

              2.  APPLICABLE ONLY TO THE SUPPLIER'S T1 CSU AND T1 DSU/CSUs OF
                  SECTION 8(c)(i)-3 -- Company shall not be obligated to
                  purchase 100% of its requirements from Supplier to respond to
                  special situations where the customer has called for a
                  specific DSU/CSU vendor product in a RFP or sale on a one-off
                  basis. Company may not, however, make any concerted effort to
                  expand marketing dollars, include as part of an offer,
                  promote, pay commission or incentives nor PEC/Com code

            products. Company should first attempt to respond with supplier's
            equipment and revert to another vendor as a last resort.

         3. In all of the above leases, Company will provide Supplier with
            written notification of the one-off sale of the other vendor's
            products. Company shall provide information consisting of product
            type, dollar value of the transaction, and rationale for the resale
            of the other vendor's product.

         4. Excluded from the exclusivity obligations of this Amendment are
            products purchased by Acquired Companies, where prior to acquisition
            by Company, these Acquired Companies purchased and included
            substantially similar product from other sources in their systems
            designs. However, not excluded are substantially similar
            Stand-Alone Products where a Supplier Access Product is or becomes
            a feasible alternative. To determine if such substantially similar
            product is or becomes a feasible alternative, Company and Supplier
            shall utilize the Benchmarking provisions, and if required, follow
            the dispute resolution process outlined under Benchmarking. Use of
            "Other Sourced Product" in any form other than the original offer
            will be subject to the exclusivity provisions and not an exception
            under subsection 4. Additionally, if after acquisition, the Acquired
            Company develops a need for an Access Product substantially similar
            to those defined herein, then they shall satisfy 100% of this
            requirement from Supplier.  In no way is this meant to relieve
            Company of its obligations under the Noncompetition Agreement,
            dated 7/31/96.

(c)  Requests for Access Product enhancements and new features or new products
     shall process through the Quarterly Meeting process, or as needed, and
     decisions to proceed shall be based upon a business relationship that
     assures a positive business case for each party. Upon failure to reach an
     agreed upon action plan, the resolution escalation process shall go to
     Supplier CEO and Company Purchasing Vice President or designee. In the
     event of a dispute, the "industry consultant" steps described under
     SECTION 9 ("BENCHMARKING"), as amended in this Amendment, may be invoked
     by either party.

9. BENCHMARKING
On a quarterly basis, Company and Supplier shall, if requested by either party,
undertake to benchmark price, quality, product functionality, and service
performance of material offered by Supplier. Price shall mean general pricing
issues or trends, not specific opportunities which shall continue to be handled
under the Supplier's "P Quote" process.

                                                                 Amendment No. 1

Product functionality shall mean a major function that represents an industry
trend and which is considered essential to compete in the current marketplace
and preserve market share. Singular features that Supplier may or may not have
as part of the product offering would not qualify for benchmarking. The decision
to benchmark will be presented and developed at regularly scheduled quarterly
business meetings. Prior to any benchmarking both companies shall agree upon
the framework to conduct the benchmarking process (see Exhibit B). This shall
include clear identification of industry leaders to be benchmarked.

Following the benchmark study, Supplier and Company shall review such benchmark
information and Supplier shall develop a plan of action for improving Material
Price, quality, product functionality, and service performance if such
benchmark information indicates improvements are needed when compared to the
then existing standards of the industry of comparable Price, quality, product
functionality and service. Supplier shall introduce improvements that assure
Company that Material is meeting or exceeding competitive benchmarks with
respect to: (1) Material Price within thirty (30) days after the later of such
review or objective assessment as described below, and (2) for Material
quality, product functionality, or service performance within a mutually agreed
upon period after the later of such review or objective assessment. Supplier
will provide a plan for introducing such improvements within the first thirty
(30) days of such review objective assessment. If Supplier fails to perform as
described in items 1 or 2 above, Company shall have the right to competitively
quote such Material in the marketplace. Company will give Supplier a thirty
(30) day prior written notice of such intent to place business with any other
vendor and provide Supplier that thirty (30) day period to match or beat such
other offer received by Lucent. If Supplier matches or beats such other offer,
Lucent agrees to continue to place Orders with Supplier at the new price,
quality, product functionality, and service levels subject to the terms and
conditions of this Agreement. If Supplier does not match or beat Company's
offer, Company may elect to purchase Material from another source without
further obligation under Article 8 for those Products. Where Company and
Supplier have agreed upon a schedule and the scheduled General Availability for
such new feature, functionality or quality slips without contributing fault by
Company, Company may procure a competitive product.

In the event of a dispute to approach, procedure or results of the benchmarking,
the parties agree to promptly retain an independent, non-affiliated consultant
experienced in the industry to provide an objective assessment of the issue(s)
in dispute.  The determination of the consultant shall be final and binding.

15. MANUFACTURE DISCONTINUED

Supplier shall provide Company at least one (1) year prior written notice that
any Material covered by this Agreement is recommended as a candidate to be
manufacture discontinued by Supplier. Company shall, within sixty (60) days
after receipt of Supplier's written notice, provide Supplier a written
response indicating Company's approval or disapproval of the manufacture
discontinued status of such Material based upon such Material's impact on the
Company's business, including but not limited to the Company's obligations to
its customers.

If Company does not approve of the Material being manufacture discontinued, the
parties shall negotiate in good faith to determine the final disposition of
such Material. If the parties agree that Material shall become manufacture
discontinued, Supplier shall accept Company's Orders for such manufacture
discontinued Material under the terms and conditions of this Agreement for one
(1) year from the Supplier's notification date of manufacture discontinued
status.  Once the manufacture discontinued Material is no longer available to
order by Company, Supplier agrees that the Company may procure substitute
product from alternate source without further obligation under Article 8 for
those products.

36. INDEMNITY AND INFRINGEMENT

All Work performed by Supplier under this Agreement shall be performed by
Supplier as an independent contractor and not as an agent of Company.  All
persons furnished by Supplier shall be considered solely Supplier's Employees or
agents, and Supplier shall be responsible for compliance with all applicable
laws, rules, and regulations relating to labor, working conditions, wages, and
payment of all unemployment, social security, and other payroll taxes,
including contributions when required by law.

Supplier agrees to indemnify and save harmless Company, its affiliates and its
customers and their officers, directors, employees, successors and assigns (all
hereinafter referred to in this clause as "Company") from and against any
losses, damages, claims, demands, suits, liabilities, and expenses (including
reasonable attorney's fees) that arise out of or result from: (1) injuries or
death to persons or damage to property, including theft, in any way arising out
of or occasioned by, caused or alleged to have been caused by or on account of
the Material, or the performance or Work or Services performed by Supplier or
persons furnished by Supplier; (2) assertions under Workers' Compensation or
similar acts made by persons furnished by Supplier or by any subcontractor or by
reason of any injuries to such persons for which Company would be responsible
under Workers' Compensation or similar acts if the persons were employed by
Company; (3) any failure by Supplier to perform Supplier's

obligations under this Indemnity and Infringement Section; and/or (4) any
infringement or claim of infringement of any patent, trademark, copyright,
trade secret, or other intellectual property right of third parties based
on the manufacture, repair, sale, use, importation, reproduction and/or
distribution of Material furnished to Company hereunder, and/or any part,
component, feature or design of such Material, except that this infringement
arise solely and directly from Company supplied parts or components, or from
Supplier's required adherence to Company's written instructions or
Specifications which are so specified that such adherence directly causes
such claims or infringement and which instructions or Specifications require
the use of Material other than (i) commercial material which is available on
the open market or the same as such Material or (ii) Material of Supplier's
origin, design or selection.

In the case of the infringement indemnity, if Company's or its customers'
manufacture, repair, use, sale, importation, reproduction and/or distribution
of Material is restricted or prevented by injunction, court order or negotiated
settlement on account of such infringement, Supplier shall, at its expense:
(i) procure for Company and Company's customers the right to continue
manufacturing, using, selling, importing, reproducing and/or distributing such
Material; or (ii) replace such Material with a non-infringing product
substantially complying with such Material's Specifications and satisfactory to
Company; or (iii) modify such Material so it becomes non-infringing and
performs in a substantially similar manner to the original Material and
satisfactory to Company; or (iv) in the event of inability to reasonably
perform any of the foregoing, refund to Company the purchase price for affected
Material.

Supplier agrees to defend Company, at Company's request, against any of the
referenced claims, demands, or suits at Supplier's expense. Company agrees to
notify Supplier within a reasonable time of any written claims or demands
against Company for which Supplier is responsible under this Clause.


38. LATE DELIVERY/LIQUIDATED DAMAGES AND CANCELLATIONS

Supplier agrees that in the event that Company is able to provide to Supplier
demonstrable evidence that any delay by Supplier in delivering any Material
committed to by Supplier under any Order caused the loss of a contract of
Company or caused Company to obtain substitute material from a third party in
order to fulfill the contract, then Company shall be permitted to source such
substitute material Order without obligation to Article 8.

These provisions concerning late delivery of conforming Material are intended
to be and shall be cumulative and in addition to every other remedy now or
hereafter possessed by Company, including but not limited to its right to
recover damages under the clause entitled WARRANTY.

39. AUDIT

Supplier shall maintain accurate and complete records including termination
charges playable by Company under this Agreement. These records shall be
maintained in accordance with recognized commercial accounting practices so
they may be readily audited and shall be held until costs have been finally
determined under this Agreement and payment or final adjustment of payment, as
the case may be, has been made. Supplier shall permit Company or Company's
Representative to examine and audit these records and all supporting records at
all reasonable times. Audits shall be made not later than one (1) calendar
year after the final delivery date of Material ordered or completion of
services rendered or one (1) calendar year after the expiration date of this
Agreement, whichever comes later.

41. DEFAULT

In the event Supplier shall be in breach of default of any of the material
terms, conditions, or covenants of this Agreement and if such breach or default
shall continue for a period of forty-five (45) days after the giving of written
notice to Supplier thereof by Company that Company intends to cancel because of
such default, then, in addition to all other rights and remedies which Company
may have at law or equity or otherwise. Company shall have the right to cancel
this Agreement and/or Orders without any charge or obligation or liability of
Company.

42. TERMINATION OF ORDER FOR CAUSE

In the event Supplier exceeds the shipping interval plus five (5) working days
as specified in an Order issued hereunder because of reasons attributable to
Supplier (other than those contained in the FORCE MAJEURE Section of this
Agreement), then in addition to all other rights and remedies of law or equity
or otherwise and without liability or obligation to Supplier, Company shall
have the right to:[***]

55. ASSIGNMENT

Except as set forth below, neither Company nor Supplier shall assign any right
or interest under this Agreement or (with respect to Supplier) under an Order
issued pursuant to this Agreement (excepting monies due or to become due) or
delegate any Work or other obligation to be performed or owed under this
Agreement or an Order

either in whole or in part without the prior written consent of the other party
which consent shall not be unreasonably withheld. Any attempted assignment or
delegation in contravention of the above provisions shall be void and
ineffective. Any assignment of monies shall be void and ineffective to the
extent that (1) Supplier shall not have given Company at least thirty (30) days
prior written notice of such assignment or (2) such assignment attempts to
impose upon Company obligations to the assignee additional to the payment of
such monies, or to preclude Company from dealing solely and directly with
Supplier in all matters pertaining to this Agreement including the negotiation
of amendments or settlements of charges due.

Notwithstanding the provisions set forth above, Company shall have the right to
assign this Agreement and to assign its rights and delegate its duties under
this Agreement either in whole or in part, at any time and without Supplier's
consent; provided however that such assignment shall only be permitted to an
affiliate or subsidiary of Company having assets greater than [***]. Company
shall give Supplier thirty (30) days prior written notice of any such
assignment. The assignment shall neither affect nor diminish any rights or
duties that Supplier or Company may then or thereafter have as to services or
Material ordered by Company prior to the effective date of the assignment.

Upon the acceptance of the assignment and assumption of the duties under this
Agreement, Company shall be released and discharged, to the extent of the
assignment, from all further duties under this Agreement as to services or
Material not ordered by Company by the effective date of the Assignment.

60. FORCE MAJEURE

Neither party shall be held responsible for any delay or failure in performance
of any part of this Agreement or Order to the extent such delay or failure is
caused by fire, flood, explosion, war, strike, embargo, government requirement,
civil or military authority, act of God, act or omission of carriers or other
similar causes beyond its control and without the fault or negligence of the
delayed or nonperforming party or its subcontractors ("force majeure
conditions"). Notwithstanding the foregoing, Supplier's liability for loss or
damage to Company's Material in Supplier's possession or control shall not be
modified by this clause. If any force majeure condition occurs, the party
delayed or unable to perform shall give immediate notice to the other party and
the party affected by the other's delay or inability to perform may elect to:
(1) suspend this Agreement or Order for the duration of the force majeure
condition and (i) at its option obtain elsewhere manufacturing or repair
services to have been furnished under this Agreement or Order, and (ii) once
the force majeure condition ceases, resume performance under this Agreement or
Order with an option in the affected party to extend the period of this
Agreement or Order up the length of time the force majeure

condition endured and/or (2) when the delay or nonperformance continues for a
period of at least thirty (30) days, terminate, at no charge, the applicable
Order or the part of it relating to Material not already shipped or Services
not already performed. Unless Written notice is given within forty-five (45)
days after the affected party is notified of the force majeure condition, (1)
shall be deemed selected.

65. EPIDEMIC CONDITION

In the event that during the term of this Agreement and for one year after the
last shipment date of Material hereunder, Company notifies Supplier (in
accordance with the NOTICES clause) that Material shows evidence of an Epidemic
Condition. Supplier shall prepare and propose a "Corrective Action Plan" (CAP)
with respect to such Material within ten (10) working days of such notification,
addressing implementation and procedure milestones for remedying such epidemic
condition(s). An extension of this time-frame is permissible upon mutual
agreement of the parties.

Upon notification of the Epidemic Condition to Supplier, Company shall have the
right to postpone shipment of unshipped Material by giving written notice of
such postponement to Supplier, pending correction of the Epidemic Condition.
Such postponement shall temporarily relieve Supplier of its shipment liability
and Company of its shipment acceptance liability. Should Supplier not agree to
the existence of an Epidemic Condition or should Company not agree to the
Corrective Action Plan, then Company shall have the right to suspend all or part
of its unshipped Orders without liability to Company until such time as a
mutually acceptable solution is reached.

An Epidemic Condition, excluding potential safety hazards, will be considered to
exist when one or more of the following conditions occur:

      1.    Failure reports or statistical sampling showing that three percent
(3%) or more of any consecutive one hundred (100) units of Material delivered to
Company or Company's customers are rejected for defective materials or
workmanship; or repair reports indicate non-conformance for the same defect of
five percent (5%) of the installed Material base.

      2.    Reliability plots of relevant data indicate that Material has actual
Mean Time Between Failures (MTBF) of less than eighty (80%) percent of the MTBF
stipulated in Specification for Material. the MTBF parameter of Material is
defined as the total operation or power-on time of any population under
observation ("T"), in hours, divided by the total number of critical failures
("n") that have occurred during the observed period. a critical failure is
defined as a failure to operate per the requirements of Specification. The total
operating time for a population is the summation of operating time of individual
units in that population. MTBF is

                                                                 Amendment No. 1
                                                                   Page 14 of 14


          expressed as MTBF=T/n. An Epidemic Condition shall exist when data
          derived from populations being tracked confirms the condition with
          eighty (80%) percent statistical confidence.

     3.   Material Dead on Arrival ("DOA") failures exceed the Epidemic DOA
          failure rate which is defined as two percent (2%) of Material
          delivered to Company or Company's customer with a one (1) month
          period.

Only major functional and visual/mechanical/appearance defects are considered
for determining Epidemic Condition. Material could be either sampled, or at
Company option, one hundred (100%) percent audited at Company warehouses,
factories, or Company's customers' locations. If Material is sampled, the data
must have eighty (80%) percent or better statistical confidence.

For the purposes of this Agreement, functional DOA shall not include Material
for which no defect is found and shall be defined as any Material that during
the test, installation or upon its first use fails to operate as expected or
specified. Visual/mechanical/appearance DOA is defined as any Material
containing one or more major defects that would make Material unfit for use or
installation. An Epidemic Condition shall not include failure due to customer
misapplication, misuse, abuse, lightning, utilization of parts not approved by
Supplier, or chain failures induced by internally or externally integrated
subassemblies.

In the event that Supplier develops a remedy for the defect(s) that caused the
Epidemic Condition and Company agrees in writing that the remedy is acceptable,
Supplier shall:

     (a)   Incorporate the remedy in the affected Material in accordance with
           Engineering Change Control procedures or manufacturing procedures,
           as applicable, agreed to by the parties.
     (b)   Ship all subsequent Material incorporating the required
           modification correcting the defect(s) at no additional charge to
           Company; and
     (c)   Repair and/or replace at Supplier's option Material that caused the
           Epidemic Condition. In the event that Company incurs costs due to
           such repair and/or replacement, including but not limited to labor
           and shipping costs, Supplier shall reimburse Company for such costs,
           as mutually determined and agreed upon by both parties. Supplier
           shall bear such risk of in transit loss and damage for such repaired
           and/or replaced Material shipped to Company.

     Supplier and Company shall mutually agree in writing as to the remedy's
implementation schedule. Supplier agrees to utilize its best efforts to
implement in accordance with agreed-upon schedule.


     In the event that Supplier is unable to develop a mutually agreeable
remedy, or does not adequately take into account the business interests of
Company, as reasonably agreed by the parties, Company may (1) develop such
remedy and implementation cost and risk of in transit loss and damage shall be
allocated between the parties as set forth in this clause, and/or (2) cancel
postponed Orders without liability and return all confirmed Material affected by
such Epidemic Condition for full refund, payable by Supplier within thirty (30)
days after receipt of returned Material (with risk of loss of in transit damage
borne by Supplier), and/or (3) terminate this Agreement without further
liability.


     All other terms and conditions shall remain unchanged.
