                               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



     We are 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.

     - 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.
Throughout this prospectus, unless otherwise specifically indicated references
to "Paradyne," "we," and "us" refer to Paradyne Networks, Inc., Paradyne
Corporation, our operating company subsidiary, and all other consolidated
subsidiaries. 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
  because we have some products with higher margins than others. 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 product sales to, and services performed for, Lucent
  constituted 35% of our total revenues in 1998. 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. After the expiration of that 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 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, 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. In 1999, we
received a letter from a third party patent owner alleging infringement by us of
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.
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 have a material adverse effect on our business, financial condition and
results of operations.


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;


     - 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
                                       10
<PAGE>   15

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 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
                                       11
<PAGE>   16

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.

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 (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.

                                       12
<PAGE>   17

     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.


     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."

                                       13

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. 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 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

                                       14
<PAGE>   19

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. 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 $29.7
million, or approximately $1.13 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
$1.42 per share to existing stockholders and an immediate dilution of $10.45 per
share to investors purchasing shares of common stock in this offering. The
following table illustrates this per share dilution:

     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;

                                       22
<PAGE>   27

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

     - 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.

</TABLE>


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 the receipt by Paradyne of approximately $3.0 million in net
proceeds 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


                                       24
<PAGE>   29

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 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 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
                                       25
<PAGE>   30


     - 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.

     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 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 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 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

                                       26
<PAGE>   31


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 will retain our revolving line of credit but 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.


Three Months Ended March 31, 1999


     Cash provided by operations for the quarter ended March 31, 1999 totaled
$6.2 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


                                       27
<PAGE>   32


by operations was offset in part by reductions in payroll related benefits which
reflect payments of 1998 commissions and management bonuses net of accruals for
similar payments in 1999 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 $5.1 million primarily reflecting debt repayments on our Bank of America
NT&SA revolving credit facility. 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 $4.1 million from $8.4 million at December 31, 1998
to $12.5 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

                                       28
<PAGE>   33


for the five month period ending December 31, 1996 and the year ended December
31, 1997. Net borrowings 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.

     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.

(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 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
                                       30
<PAGE>   35

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.

CONVENTIONAL ACCESS SOLUTIONS CONNECTING TO MULTIPLE NETWORK BACKBONE
FACILITIES. -- GRAPHIC ENTITLED "PARADYNE BROADBAND ACCESS SOLUTIONS."]


  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.



     - 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


                                       34
<PAGE>   39
       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 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
                                       35
<PAGE>   40

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.


  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
management, monitoring and control over their network access equipment and
circuits. Although advanced network management systems are an important aspect
of our products and technology, they have not been a material aspect of our
sales revenue generation. The table below includes a summary of our principal
products. A further description of such products follows the table.

  BROADBAND SOLUTIONS

     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
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

                                       39
<PAGE>   44

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.

GRAPHIC INDICATES THAT "THE PARADYNE HOTWIRE DSLAM SUPPORTS MULTIPLE TYPES OF
VOICE AND DATA TRANSPORT"]


     - 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;

        - 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.


                                       40
<PAGE>   45

     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.

     SuperLine.  SuperLine is an integrated access system that provides
integrated voice and data broadband access services to the residential and small
office/home office markets.

    - 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

                                       41
<PAGE>   46


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.

     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;

     - 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

                                       42
<PAGE>   47

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.

     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

                                       43

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 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.

                                       44
<PAGE>   49

     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 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-

                                       45
<PAGE>   50

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.


     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.

</TABLE>

     In the year ended December 31, 1998, two of our customers accounted for
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

                                       47
<PAGE>   52

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;

     - 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
                                       48
<PAGE>   53

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 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. No assurance can
be given that any necessary licenses will be available or that, if available,
such licenses can be obtained on commercially reasonable terms. In 1999, we
received a letter from a third party patent owner alleging infringement by us of
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.
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, but we currently believe that defenses
asserted by others may be applicable to us and that indemnities we have from
third party vendors may insulate us from at least some damages. If an
infringement claim is brought against us, we cannot assure you that we would
prevail and any adverse outcome could have a material adverse effect on our
business, financial condition and results of operations.



     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

                                       49
<PAGE>   54


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.

     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

                                       50
<PAGE>   55

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.

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 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.

                                       57
<PAGE>   62

     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 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,
                                       58
<PAGE>   63

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 closing 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


                                       59
<PAGE>   64


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 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.

                                       60
<PAGE>   65

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.

     The predecessor business operated a services business and personal end user
business, which Lucent retained. The predecessor business also operated a
development, manufacturing and distribution business for broadband and
narrowband access products, which was retained by Paradyne Corporation, a
high-speed access integrated circuit business, which was acquired by GlobeSpan,
a short-term equipment leasing business, which was acquired by Paradyne Credit
Corp. and a long-term equipment leasing business, which was acquired by Lease
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 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.

                                       63
<PAGE>   68


     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.

     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

                                       64
<PAGE>   69

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


                                       65

"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 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

                                       66
<PAGE>   71

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.

     TRANSACTIONS WITH PARADYNE CREDIT CORP.

     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


                                       67
<PAGE>   72

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.

                       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
                                       72
<PAGE>   77

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

                                       73
<PAGE>   78

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
of which were vested. However, all of these shares are subject to lock-up
agreements. Immediately after the completion of this offering, we intend to file
registration statements on Form S-8 under the Securities Act to register all of
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
otherwise dispose of any of their shares for a period of 180 days after the date
of this offering. Donaldson, Lufkin & Jenrette, however, may in its sole
discretion, at any time without notice, release all or any portion of the shares
subject to lock-up agreements.

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
manner of sale, notice filing, volume limitation or notice provisions of Rule
144. Therefore, unless otherwise 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 underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares of common stock
offered hereby are subject to approval by their counsel of certain legal matters
and to certain other conditions. The underwriters are obligated to purchase and
accept delivery of all the shares of common stock offered hereby (other than
those shares covered by the over-allotment option described below) if any are
purchased.

     The underwriters initially propose to offer the shares of common stock in
part directly to the public at the initial public offering price set forth on
the cover page of this prospectus and in part to certain dealers (including the
underwriters) at such price less a concession not in excess of $          per
share. The underwriters may allow, and such dealers may re-allow, to certain
other dealers a concession not in excess of $          per share. After the
initial offering of the common stock, the public offering price and other
selling terms may be changed by the representatives of the underwriters at any
time without notice.

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

     The following table shows the underwriting fees to be paid to the
underwriters by Paradyne and the selling stockholders in connection with this
offering. These amounts are shown assuming both no exercise and full exercise of
the underwriters' option to purchase additional shares of Paradyne common stock.

     DLJdirect Inc., an affiliate of Donaldson, Lufkin & Jenrette Securities
Corporation and a member of the selling group, is facilitating the distribution
of the shares sold in the offering over the Internet. The underwriters have

     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.L.C., 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;

                                       77
<PAGE>   82

     - 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.

                                 LEGAL MATTERS

     The legality of the shares of common stock offered hereby will be passed
upon for us by Cooley Godward LLP, Palo Alto, California. Certain legal matters

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."

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 its
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:

           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.

  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

     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:

accounting for stock options. Accordingly, no compensation costs at the grant
dates are recorded for options granted at fair market value. Had compensation
cost for the Company's option plans been determined based on the fair value at
the grant dates as prescribed by Statement of Financial Accounting Standards No.

     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.

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, 1997. 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

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.



     Paradyne Partners' continuing guaranty under the Credit Agreement was
canceled in March 1999 (see Note 9). Effective February 25, 1999, Paradyne
Partners was renamed Communication Partners, L.P.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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


     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 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.



     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.

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.

                                 (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

                                      II-1
<PAGE>   112

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.

     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.

    several Underwriters
    named in Schedule I hereto
    c/o Donaldson, Lufkin & Jenrette
      Securities Corporation
      277 Park Avenue
      New York, New York 10172

Ladies and Gentlemen:

         Paradyne Networks, Inc., a Delaware corporation (the "COMPANY"),
proposes to issue and sell to the several underwriters named in Schedule I
hereto (the "UNDERWRITERS"), and certain stockholders of the Company named in
Schedule II hereto (the "SELLING STOCKHOLDERS") severally propose to sell to the
several Underwriters, an aggregate of 6,000,000 shares of the common stock, par
value $.001 per share, of the Company (the "FIRM Shares"), of which 4,000,000
shares are to be issued and sold by the Company and 2,000,000 shares are to be
sold by the Selling Stockholders, each Selling Stockholder selling the amount
set forth opposite such Selling Stockholder's name in Schedule II hereto. The
Selling Stockholders also propose to sell to the several Underwriters not more
than an additional 900,000 shares of the Company's common stock, par value $.001
per share (the "ADDITIONAL SHARES"), if requested by the Underwriters as
provided in Section 2. The Firm Shares and the Additional Shares are hereinafter
referred to collectively as the "SHARES". The shares of common stock of the
Company to be outstanding after giving effect to the sales contemplated hereby
are

<PAGE>   2

hereinafter referred to as the "COMMON STOCK". The Company and the Selling
Stockholders are hereinafter sometimes referred to collectively as the
"SELLERS".

         SECTION 1. Registration Statement and Prospectus. The Company has
prepared and filed with the Securities and Exchange Commission (the
"COMMISSION") in accordance with the provisions of the Securities Act of 1933,
as amended, and the rules and regulations of the Commission thereunder
(collectively, the "ACT"), a registration statement on Form S-1, including a
prospectus, relating to the Shares. The registration statement, as amended at
the time it became effective, including the information (if any) deemed to be
part of the registration statement at the time of effectiveness pursuant to Rule
430A under the Act, is hereinafter referred to as the "REGISTRATION STATEMENT";
and the prospectus in the form first used to confirm sales of Shares is
hereinafter referred to as the "PROSPECTUS". If the Company has filed or is
required pursuant to the terms hereof to file a registration statement pursuant
to Rule 462(b) under the Act registering additional shares of Common Stock (a
"RULE 462(B) REGISTRATION STATEMENT"), then, unless otherwise specified, any
reference herein to the term "Registration Statement" shall be deemed to include
such Rule 462(b) Registration Statement.

         SECTION 2. Agreements to Sell and Purchase and Lock-Up Agreements. On
the basis of the representations and warranties contained in this Agreement, and
subject to its terms and conditions, (i) the Company agrees to issue and sell
4,000,000 Firm Shares, (ii) each Selling Stockholder agrees, severally and not
jointly, to sell the number of Firm Shares set forth opposite such Selling
Stockholder's name in Schedule II hereto and (iii) each Underwriter agrees,
severally and not jointly, to purchase from each Seller at a price per Share of
$________ (the "PURCHASE PRICE") the number of Firm Shares (subject to such
adjustments to eliminate fractional shares as you may determine) that bears the
same proportion to the total number of Firm Shares to be sold by such Seller as
the number of Firm Shares set forth opposite the name of such Underwriter in
Schedule I hereto bears to the total number of Firm Shares.

         On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, each Selling Stockholder
agrees, severally and not jointly, to sell to the Underwriters at the Purchase
Price the number of Additional Shares (subject to such adjustments to eliminate
fractional shares as you may determine) equal to (i) the total number of
Additional Shares purchased by the Underwriters multiplied by (ii) a fraction,
the numerator of which is the number of Firm Shares set forth opposite such
Selling Stockholder's name in Schedule II hereto and the denominator of which is
the total number of Firm Shares. Additional Shares may be purchased solely for
the purpose of covering over-allotments made in connection with the offering of
the Firm Shares. The Underwriters may exercise their right to purchase
Additional Shares in whole or in part from time to time by giving written notice
thereof to the Attorneys (as defined herein) within 30 days after the date of
this Agreement. You shall give any such notice on behalf of the Underwriters and
such notice shall specify the aggregate number of Additional Shares to be
purchased pursuant to such exercise and the date for payment and delivery
thereof, which date shall be a business day (i) no earlier than two business
days after such notice has been given (and, in any event, no earlier than the
Closing Date (as


                                      -2-
<PAGE>   3

hereinafter defined)) and (ii) no later than ten business days after such notice
has been given. If any Additional Shares are to be purchased, each Underwriter,
severally and not jointly, agrees to purchase from the Selling Stockholders the
number of Additional Shares (subject to such adjustments to eliminate fractional
shares as you may determine) which bears the same proportion to the total number
of Additional Shares to be purchased from such Stockholder as the number of Firm
Shares set forth opposite the name of such Underwriter in Schedule I bears to
the total number of Firm Shares.

         Each Seller hereby agrees not to (i) 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

accounting principles the information required to be stated therein; and the

statements and the books and records of the Company.

         (s) The Company is not and, after giving effect to the offering and
sale of the Shares and the application of the proceeds thereof as described in

         (t) Except as disclosed in the Registration Statement and the

         (u) Since the respective dates as of which information is given in the
Prospectus other than as set forth in the Prospectus (exclusive of any

fee simple to all real property and good and marketable title to all personal
property owned by them which is material to the business of the Company and its
subsidiaries, in each case free and clear of all liens, encumbrances and defects
except such as are described in the Prospectus or such as do not materially
affect the value of such property and do not interfere with the use made and
proposed to be made of such property by the Company and its subsidiaries; and
any real property and buildings held under lease by the Company and its
subsidiaries are held by them under valid, subsisting and enforceable leases
with such exceptions as are not material and do not interfere with the use made
and proposed

                                      -13-

to be made of such property and buildings by the Company and its subsidiaries,

Prospectus.

         (w) The Company and its subsidiaries own or possess, or can acquire on
reasonable terms, all patents, patent rights, licenses, inventions, copyrights,
know-how (including trade secrets and other unpatented and/or unpatentable
proprietary or confidential information, systems or procedures), trademarks,
service marks and trade names ("INTELLECTUAL PROPERTY") currently employed by
them in connection with the business now operated by them except where the
failure to own or possess or otherwise be able to acquire such Intellectual
Property would not, singly or in the aggregate, have a material adverse effect
on the business, prospects, financial condition or results of operations of the
Company and its subsidiaries, taken as a whole. Except as disclosed in the

other material expenditures will have to be made in order to continue such
insurance or (ii) has any reason to believe that it will not be able to renew
its existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers at a cost that would not have a material
adverse effect on the business, prospects, financial conditions or results of
operations of the Company and its subsidiaries, taken as a whole.

material adverse effect on the business, prospects, financial condition or
results of operations of the Company and its subsidiaries, taken as a whole. To
the best of the Company's knowledge, no collective bargaining organizing
activities are taking place with respect to the Company or any of its
subsidiaries.

         (aa) The Company and each of its subsidiaries maintains a system of
internal accounting controls sufficient to provide reasonable assurance that (i)
transactions are executed in accordance with management's general or specific
authorizations; (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain asset accountability; (iii) access to
assets is permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

         (bb) All material tax returns required to be filed by the Company and
each of its subsidiaries in any jurisdiction have been filed, other than those

Company or any of its subsidiaries have been paid, other than those being
contested in good faith and for which adequate reserves have been provided.

         (cc) The Company and its subsidiaries have complied and are in
compliance with all foreign, federal, state and local statutes, executive
orders, proclamations, regulations, rules, directives, decrees, ordinances and

importation of merchandise, the export or reexport of products, services and
technology, and the terms and conduct of international transactions applicable
to the Company and its subsidiaries in connection with the conduct of the
business of the Company and its subsidiaries (including, without limitation, as
the same relates to record keeping requirements) ("INTERNATIONAL TRADE LAWS AND
REGULATIONS"), except where failure to comply therewith would not, singly or in
the aggregate, have a material adverse effect on the business, prospects,
financial condition or results of operation of the Company and its subsidiaries,
taken as a whole; neither the Company nor any of its subsidiaries has made or
provided any material false statement or material omission to any agency of any
federal, state or local government, purchasers of products, or foreign
government or foreign agency, in connection with the exportation of merchandise

exportation of


                                      -15-

any item), the importation of merchandise or other approvals required by a
foreign government or agency or any other requirement relating to any
International Trade Laws and Regulations.

         (dd) The Company has reviewed its operations and the operations of its
subsidiaries and any third parties with which the Company or any of its
subsidiaries has a material relationship to evaluate the extent to which the
business or operations of the Company or any of its subsidiaries will be
affected by the Year 2000 Problem (as defined below). As a result of such
review, the Company has no reason to believe, and does not believe, that the
Year 2000 Problem will have a material adverse effect on the business,
prospects, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole. The "YEAR 2000 PROBLEM" as used herein means any
risk that the computer hardware or software used in the receipt, transmission,
storage, retrieval, retransmission or other utilization of data or in the
operation of mechanical or electrical systems of any kind will not, in the case
of dates or time periods occurring after December 31, 1999, function at least as
effectively as in the case of dates or time periods occurring prior to January
1, 2000.

         (ee) The Company and its subsidiaries have obtained all Authorizations

commissions ("PUCS"), and otherwise under the Telecommunications Act of 1996
(the "1996 ACT"), the Communications Act of 1934, as amended (the
"COMMUNICATIONS ACT"), and the rules and regulations under the 1996 Act and the
Communications Act (the "RULES AND REGULATIONS"), in each case necessary for the
conduct of the business of the Company and its subsidiaries as described in the
Registration Statement and the Prospectus. All such Authorizations have been
duly and validly issued and are in full force and effect and neither the Company
nor any of its subsidiaries is in violation of any of the terms and conditions
of any such Authorizations, except for any violation which, singly or in the
aggregate, would not have a material adverse effect on the business, prospects,
financial condition or results of operations of the Company and its
subsidiaries, taken as a whole.

         (ff) There is no outstanding adverse judgment, decree or order that has
been issued by the FCC or any state PUC against the Company or any of its
subsidiaries or any action, proceeding or investigation pending or threatened by
the FCC or any state PUC against the Company or any of its subsidiaries which,
singly or in the aggregate, if the subject of an unfavorable decision, ruling or
finding, would have a material adverse effect on the business, prospects,
financial condition or results of operations of the Company and its
subsidiaries, taken as a whole.

         (gg) Each certificate signed by any officer of the Company and
delivered to the Underwriters or counsel for the Underwriters shall be deemed to

matters covered thereby.

any Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Securities Exchange Act of 1934,


                                      -18-
<PAGE>   19

as amended (the "EXCHANGE ACT"), from and against any and all losses, claims,
damages, liabilities and judgments (including, without limitation, any legal or
other expenses incurred in connection with investigating or defending any
matter, including any action, that could give rise to any such losses, claims,
damages, liabilities or judgments) caused by any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement (or
any amendment thereto), the Prospectus (or any amendment or supplement thereto)
or any preliminary prospectus, or caused by any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make

damages, liabilities or judgments are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to any Underwriter furnished in writing to the Company by such Underwriter
through you expressly for use therein; provided, however, that the foregoing
indemnity agreement with respect to any preliminary prospectus shall not inure

amended or supplemented (so long as the Prospectus and any amendments or
supplements thereto was provided by the Company to the several Underwriters in
the requisite quantity and on a timely basis to permit proper delivery on or
prior to the Closing Date) to the person asserting any losses, claims, damages,
liabilities or judgments caused by any untrue statement or alleged untrue
statement of a material fact contained in such preliminary prospectus, or caused
by any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, if
such material misstatement or omission or alleged material misstatement or
omission was cured in the Prospectus, as so amended or supplemented, and such
Prospectus was required by law to be delivered at or prior to the written
confirmation of sale to such person.

         (b) Each Selling Stockholder agrees, severally and not jointly, to
indemnify and hold harmless each Underwriter, its directors, its officers and
each person, if any, who controls any Underwriter within the meaning of Section
15 of the Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages, liabilities and judgments (including, without
limitation, any legal or other expenses incurred in connection with
investigating or defending any matter, including any action, that could give
rise to any such losses, claims, damages, liabilities or judgments) caused by
any untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement (or any amendment thereto), the Prospectus (or any
amendment of supplement thereto) or any preliminary prospectus, or caused by any
omission or alleged omission to state therein a material fact required to be

         (c) Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless (i) the Company, its directors, its officers who sign the
Registration Statement and each person, if any, who controls the Company within

same extent as the foregoing indemnity


                                      -19-
<PAGE>   20

from the Company to such Underwriter and (ii) each Selling Stockholder and each
person, if any, who controls such Selling Stockholder within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act to the same extent as
the foregoing indemnity from such Selling Stockholder to such Underwriter, but
in the case of Sections 8(c)(i) and 8(c)(ii) only with reference to information

         (d) The Company and the Operating Subsidiary, jointly and severally,
agree to indemnify and hold harmless each Selling Stockholder, its directors,
its officers and each person, if any, who controls any Selling Stockholder
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
from and against any and all losses, claims, damages, liabilities and judgments
(including, without limitation, any legal or other expenses incurred in
connection with investigating or defending any matter, including any action,
that could give rise to any such losses, claims, damages, liabilities or
judgments) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement (or any amendment
thereto), the Prospectus (or any amendment or supplement thereto) or any
preliminary prospectus, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the

         (e) Each Selling Stockholder agrees, severally and not jointly, to

to the same extent as the foregoing indemnity from the Company to such Selling
Stockholder, but only with reference to information relating to such Selling
Stockholder furnished in writing to the Company by such Selling Stockholder
expressly for use in the Registration Statement (or any amendment thereto), the
Prospectus (or any amendment or supplement thereto) or any preliminary
prospectus.

         (f) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a), 8(b), 8(c),
8(d) or 8(e) (the "INDEMNIFIED PARTY"), the indemnified party shall promptly
notify the person against whom such indemnity may be sought (the "INDEMNIFYING
PARTY") in writing and the indemnifying party shall assume the defense of such
action, including the employment of counsel reasonably satisfactory to the
indemnified party and the payment of all fees and expenses of such counsel, as
incurred (except that in the case of any action in respect of which indemnity
may be sought pursuant to both Section 8(a) or 8(b) on the one hand and Section
8(c) on the other hand, the Underwriter shall not be required to assume the
defense of such action pursuant to this Section 8(f), but may employ separate
counsel and


                                      -20-
<PAGE>   21

participate in the defense thereof, but the fees and expenses of such counsel,
except as provided below, shall be at the expense of such Underwriter). Any
indemnified party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for (i) the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all Underwriters, their officers and directors and all persons, if any, who
control any Underwriter within the meaning of either Section 15 of the Act or
Section 20 of the Exchange Act, (ii) the fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) for the Company,
its directors, its officers who sign the Registration Statement and all persons,
if any, who control the Company within the meaning of either such Section and
(iii) the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all Selling Stockholders and all persons, if
any, who control any Selling Stockholder within the meaning of either such
Section, and all such fees and expenses shall be reimbursed as they are
incurred. In the case of any such separate firm for the Underwriters, their
officers and directors and such control persons of any Underwriters, such firm
shall be designated in writing by Donaldson, Lufkin & Jenrette Securities
Corporation. In the case of any such separate firm for the Company and such
directors, officers and control persons of the Company, such firm shall be
designated in writing by the Company. In the case of any such separate firm for
the Selling Stockholders and such control persons of any Selling Stockholders,
such firm shall be designated in writing by the Selling Stockholders holding a
majority of the outstanding shares of Common Stock held by the Selling
Stockholders as a group. The indemnifying party shall indemnify and hold
harmless the indemnified party from and against any and all losses, claims,
damages, liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than 60 days after the indemnifying party
shall have received a request from the indemnified party for reimbursement for
the fees and expenses of counsel (in any case where such fees and expenses are
at the expense of the indemnifying party) and, prior to the date of such
settlement, the indemnifying party shall have failed to comply with such
reimbursement request. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement or compromise of, or
consent to the entry of judgment with respect to, any pending or threatened
action in respect of which the indemnified party is or could


                                      -21-
<PAGE>   22

have been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the indemnified party.

         (g) To the extent the indemnification provided for in this Section 8 is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Sellers and the Operating Subsidiary on the one hand and the Underwriters on the
other hand from the offering of the Shares or (ii) if the allocation provided by
clause 8(g)(i) above is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
8(g)(i) above but also the relative fault of the Sellers and the Operating
Subsidiary on the one hand and the Underwriters on the other hand in connection
with the statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative benefits received by the Sellers and the Operating
Subsidiary on the one hand and the Underwriters on the other hand shall be
deemed to be in the same proportion as the total net proceeds from the offering
(after deducting underwriting discounts and commissions, but before deducting
expenses) received by the Sellers, and the total underwriting discounts and
commissions received by the Underwriters, bear to the total price to the public
of the Shares, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault of the Sellers and the Operating Subsidiary on
the one hand and the Underwriters on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, the Operating Subsidiary, or the
Selling Stockholders on the one hand or the Underwriters on the other hand and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

         The Sellers, the Operating Subsidiary and the Underwriters agree that
it would not be just and equitable if contribution pursuant to this Section 8(g)
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in the immediately
preceding paragraph. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, liabilities or judgments referred to in
the immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
indemnified party in connection with investigating or defending any matter,
including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments. Notwithstanding the provisions of this
Section 8, (i) no Underwriter shall be


                                      -22-
<PAGE>   23

required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission and (ii) the aggregate liability of
any Selling Stockholder pursuant to this Section 8 shall be limited to the net
proceeds from the offering of the Shares (before deducting expenses) received by
such Selling Stockholder. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute pursuant to this
Section 8(g) are several in proportion to the respective number of Shares
purchased by each of the Underwriters hereunder and not joint.

         (h) The remedies provided for in this Section 8 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

         (i) Each Selling Stockholder hereby designates Paradyne Networks, Inc.,
8545 126th Avenue North, Largo, Florida 33773, as its authorized agent, upon
which process may be served in any action which may be instituted in any state
or federal court in the State of New York by any Underwriter, any director or
officer of any Underwriter or any person controlling any Underwriter asserting a
claim for indemnification or contribution under or pursuant to this Section 8 or
Section 9, and each Selling Stockholder will accept the jurisdiction of such
court in such action, and waives, to the fullest extent permitted by applicable
law, any defense based upon lack of personal jurisdiction or venue. A copy of
any such process shall be sent or given to such Selling Stockholder, at the
address for notices specified in Section 13.

         SECTION 9. Indemnification of QIU. (a) The Company and the Operating
Subsidiary, jointly and severally, agree to indemnify and hold harmless the QIU,
its directors, its officers and each person, if any, who controls the QIU within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and
against any and all losses, claims, damages, liabilities and judgments
(including, without limitation, any legal or other expenses incurred in
connection with investigating or defending any matter, including any action,
that could give rise to any such losses, claims, damages, liabilities or
judgments) related to, based upon or arising out of (i) any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement (or any amendment thereto), the Prospectus (or any amendment or
supplement thereto) or any preliminary prospectus, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading or (ii) the QIU's
activities as QIU under its engagement pursuant to Section 2, except in the case
of this clause (ii) insofar as any such losses, claims, damages, liabilities or
judgments are found in a final judgment by a court of competent jurisdiction,
not subject to further appeal, to have resulted solely from the willful
misconduct or gross negligence of the QIU.

                                      -23-
<PAGE>   24

         (b) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 9(a) or Section
9(b) (the "QIU INDEMNIFIED PARTY"), the QIU Indemnified Party shall promptly
notify the person against whom such indemnity may be sought (the "QIU
INDEMNIFYING PARTY") in writing and the QIU Indemnifying Party shall assume the
defense of such action, including the employment of counsel reasonably
satisfactory to the QIU Indemnified Party and the payment of all fees and
expenses of such counsel, as incurred. Any QIU Indemnified Party shall have the
right to employ separate counsel in any such action and participate in the
defense thereof, but the fees and expenses of such counsel shall be at the
expense of the QIU Indemnified Party unless (i) the employment of such counsel
shall have been specifically authorized in writing by the QIU Indemnifying
Party, (ii) the QIU Indemnifying Party shall have failed to assume the defense
of such action or employ counsel reasonably satisfactory to the QIU Indemnified
Party or (iii) the named parties to any such action (including any impleaded
parties) include both the QIU Indemnified Party and the QIU Indemnifying Party,
and the QIU Indemnified Party shall have been advised by such counsel that there
may be one or more legal defenses available to it which are different from or
additional to those available to the QIU Indemnifying Party (in which case the
QIU Indemnifying Party shall not have the right to assume the defense of such
action on behalf of the QIU Indemnified Party). In any such case, the QIU
Indemnifying Party shall not, in connection with any one action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for all QIU Indemnified Parties, which firm shall be designated by the
QIU, and all such fees and expenses shall be reimbursed as they are incurred.
The QIU Indemnifying Party shall indemnify and hold harmless the QIU Indemnified
Party from and against any and all losses, claims, damages, liabilities and
judgments by reason of any settlement of any action (i) effected with its
written consent or (ii) effected without its written consent if the settlement
is entered into more than twenty business days after the QIU Indemnifying Party
shall have received a request from the QIU Indemnified Party for reimbursement
for the fees and expenses of counsel (in any case where such fees and expenses
are at the expense of the QIU Indemnifying Party) and, prior to the date of such
settlement, the QIU Indemnifying Party shall have failed to comply with such
reimbursement request. The QIU Indemnifying Party shall not, without the prior
written consent of the QIU Indemnified Party, effect any settlement or
compromise of, or consent to the entry of judgment with respect to, any pending
or threatened action in respect of which the QIU Indemnified Party is or could
have been a party and indemnity or contribution may be or could have been sought
hereunder by the QIU Indemnified Party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the QIU Indemnified Party from
all liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the QIU Indemnified Party.

         (c) To the extent the indemnification provided for in this Section 9 is
unavailable to a QIU Indemnified Party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each QIU
Indemnifying Party,

                                      -24-
<PAGE>   25

in lieu of indemnifying such QIU Indemnified Party, shall contribute to the
amount paid or payable by such QIU Indemnified Party as a result of such losses,
claims, damages, liabilities and judgments (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Operating Subsidiary on the one hand and the QIU on the other hand from the
offering of the Shares or (ii) if the allocation provided by clause 9(d)(i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause 9(d)(i) above
but also the relative fault of the Company and the Operating Subsidiary on the
one hand and the QIU on the other hand in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or
judgments, as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Operating Subsidiary on the one hand
and the QIU on the other hand shall be deemed to be in the same proportion as
the total net proceeds from the offering (after deducting underwriting discounts
and commissions, but before deducting expenses) received by the Company as set
forth in the table on the cover page of the Prospectus, and the fee received by
the QIU pursuant to Section 2, bear to the sum of such total net proceeds and
such fee. The relative fault of the Company and the Operating Subsidiary on the
one hand and the QIU on the other hand shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Operating Subsidiary on the one hand
or the QIU on the other hand and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission
and whether the QIU's activities as QIU under its engagement pursuant to Section
2 involved any willful misconduct or gross negligence on the part of the QIU.

         The Company, the Operating Subsidiary and the QIU agree that it would
not be just and equitable if contribution pursuant to this Section 9(d) were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by a QIU Indemnified
Party as a result of the losses, claims, damages, liabilities or judgments
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred
by such QIU Indemnified Party in connection with investigating or defending any
matter, including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.

         (d) The remedies provided for in this Section 9 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
QIU Indemnified Party at law or in equity.

         SECTION 10. Conditions of Underwriters' Obligations. The several
obligations of the Underwriters to purchase the Firm Shares under this Agreement
are subject to the satisfaction of each of the following conditions:

                                      -25-
<PAGE>   26

Operating Subsidiary contained in this Agreement shall be true and correct on

Statement after the effectiveness of this Agreement, such Rule 462(b)
Registration Statement shall have become effective by 10:00 P.M., New York City
time, on the date of this Agreement; and no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been commenced or shall be pending
before or contemplated by the Commission.

         (c) You shall have received on the Closing Date a certificate dated the
Closing Date, signed by Andrew May, in his capacity as the President and Chief

and 10(b) and that each of the Company and the Operating Subsidiary has complied
with all of the agreements and satisfied all of the conditions herein contained
and required to be complied with or satisfied by the Company and the Operating

a prospective change in the capital stock or in the long-term debt of the

subsidiaries shall have incurred any liability or obligation, direct or
contingent, the effect of which, in any such case described in clause 10(d)(i),
10(d)(ii) or 10(d)(iii), in your judgment, is material and adverse and, in your
judgment, makes it impracticable to market the Shares on the terms and in the
manner contemplated in the Prospectus.

         (e) All the representations and warranties of each Selling Stockholder
contained in this Agreement shall be true and correct on the Closing Date with
the same force and effect as if made on and as of the Closing Date and you shall

independent check or verification except as specified.

                                      -27-
<PAGE>   28

         (n) The Company shall have delivered to you the agreements specified in

         (o) The Shares shall have been duly listed for quotation on the Nasdaq

executed United States Treasury Department Form W-8 (or other applicable form or
statement specified by Treasury Department regulations in lieu thereof).

         (r) You shall have received on the Closing Date such additional
documents (including, without limitation, opinions of counsel, certificates and

         The several obligations of the Underwriters to purchase any Additional

Closing Date of such documents (including, without limitation, opinions of
counsel, certificates and agreements) as you may reasonably request with respect
to the good standing of the Company and the Operating Subsidiary, the due
authorization and issuance of such Additional Shares and other matters related
to the issuance of such Additional Shares.

         SECTION 11. Effectiveness of Agreement and Termination. This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

         This Agreement may be terminated at any time on or prior to the Closing
Date by you by written notice to the Sellers if any of the following has
occurred: (i) any outbreak or escalation of hostilities or other national or
international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market the
Shares on the terms and in the manner contemplated in the Prospectus, (ii) the
suspension or material limitation of trading in securities or other instruments
on the New York Stock Exchange, the American Stock Exchange, the Chicago Board
of Options Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade
or the Nasdaq National Market or limitation on prices for securities or other
instruments on any such exchange or the Nasdaq National Market, (iii) the
suspension of trading of any securities


                                      -28-
<PAGE>   29

of the Company on any exchange or in the over-the-counter market, (iv) the
enactment, publication, decree or other promulgation of any federal or state
statute, regulation, rule or order of any court or other governmental authority
which in your opinion materially and adversely affects, or will materially and
adversely affect, the business, prospects, financial condition or results of
operations of the Company and its subsidiaries, taken as a whole, (v) the
declaration of a banking moratorium by either federal or New York State
authorities or (vi) the taking of any action by any federal, state or local
government or agency in respect of its monetary or fiscal affairs which in your
opinion has a material adverse effect on the financial markets in the United
States.

         If on the Closing Date or on an Option Closing Date, as the case may
be, any one or more of the Underwriters shall fail or refuse to purchase the
Firm Shares or Additional Shares, as the case may be, which it has or they have
agreed to purchase hereunder on such date and the aggregate number of Firm
Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase is not more
than one-tenth of the total number of Firm Shares or Additional Shares, as the
case may be, to be purchased on such date by all Underwriters, each
non-defaulting Underwriter shall be obligated severally, in the proportion which
the number of Firm Shares set forth opposite its name in Schedule I bears to the
total number of Firm Shares which all the non-defaulting Underwriters have
agreed to purchase, or in such other proportion as you may specify, to purchase
the Firm Shares or Additional Shares, as the case may be, which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase on such
date; provided that in no event shall the number of Firm Shares or Additional
Shares, as the case may be, which any Underwriter has agreed to purchase
pursuant to Section 2 be increased pursuant to this Section 11 by an amount in
excess of one-ninth of such number of Firm Shares or Additional Shares, as the
case may be, without the written consent of such Underwriter. If on the Closing
Date any Underwriter or Underwriters shall fail or refuse to purchase Firm
Shares and the aggregate number of Firm Shares with respect to which such
default occurs is more than one-tenth of the aggregate number of Firm Shares to
be purchased by all Underwriters and arrangements satisfactory to you, the
Company and the Selling Stockholders for purchase of such Firm Shares are not
made within 48 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter, the Company, the
Operating Subsidiary or the Selling Stockholders. In any such case which does
not result in termination of this Agreement, either you or the Sellers shall
have the right to postpone the Closing Date, but in no event for longer than
seven days, in order that the required changes, if any, in the Registration
Statement and the Prospectus or any other documents or arrangements may be
effected. If, on an Option Closing Date, any Underwriter or Underwriters shall
fail or refuse to purchase Additional Shares and the aggregate number of
Additional Shares with respect to which such default occurs is more than
one-tenth of the aggregate number of Additional Shares to be purchased on such
date, the non-defaulting Underwriters shall have the option to (i) terminate
their obligation hereunder to purchase such Additional Shares or (ii) purchase
not less than the number of Additional Shares that such non-defaulting
Underwriters would have been obligated to purchase on such date in the absence
of such default. Any action taken


                                      -29-
<PAGE>   30

under this paragraph shall not relieve any defaulting Underwriter from liability
in respect of any default of any such Underwriter under this Agreement.

         SECTION 12. Agreements of the Selling Stockholders. Each Selling
Stockholder agrees with you and the Company:

         (a) to pay or to cause to be paid (i) all transfer taxes payable in
connection with the transfer of the Shares to be sold by such Selling
Stockholder to the Underwriters and (ii) the fees, disbursements and expenses of
counsel to the Selling Stockholders incurred or made in connection herewith and
in connection with the transactions contemplated by the Registration Statement
and the Prospectus; and

         (b) to do and perform all things to be done and performed by such
Selling Stockholder under this Agreement prior to the Closing Date and to
satisfy all conditions precedent to the delivery of the Shares to be sold by
such Selling Stockholder pursuant to this Agreement.

         SECTION 13. Miscellaneous. Notices given pursuant to any provision of
this Agreement shall be addressed as follows: (i) if to the Company or the
Operating Subsidiary, to Paradyne Networks, Inc., 8545 126th Avenue North,
Largo, Florida 33773, Attention: General Counsel, (ii) if to the Selling
Stockholders, to [NAME OF ATTORNEY-IN-FACT], [ADDRESS OF ATTORNEY-IN-FACT] and
(iii) if to any Underwriter or to you, to you c/o Donaldson, Lufkin & Jenrette
Securities Corporation, 277 Park Avenue, New York, New York 10172, Attention:
Syndicate Department, or in any case to such other address as the person to be
notified may have requested in writing.

         The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company, the Selling Stockholders and the
several Underwriters set forth in or made pursuant to this Agreement shall
remain operative and in full force and effect, and will survive delivery of and
payment for the Shares, regardless of (i) any investigation, or statement as to
the results thereof, made by or on behalf of any Underwriter, the officers or
directors of any Underwriter, any person controlling any Underwriter, any QIU
Indemnified Party, the Company, the officers or directors of the Company, any
person controlling the Company, any Selling Stockholder or any person
controlling such Selling Stockholder, (ii) acceptance of the Shares and payment
for them hereunder and (iii) termination of this Agreement.

         If for any reason the Shares are not delivered by or on behalf of any
Seller as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 11), the Sellers agree, jointly and severally, to
reimburse the several Underwriters for all out-of-pocket expenses (including,
without limitation, the fees and disbursements of counsel) incurred by them.
Notwithstanding any termination of this Agreement, the Company shall be liable
for all expenses which it has agreed to pay pursuant to Section 5(i). The
Sellers also agree, jointly and severally, to reimburse the several
Underwriters, their directors and officers, any persons controlling any of the
Underwriters and the QIU Indemnified Parties for any and all fees and expenses
(including, without limitation, the

                                      -30-
<PAGE>   31

fees disbursements of counsel) incurred by them in connection with enforcing
their rights hereunder (including, without limitation, pursuant to Sections 8
and 9).

         Except as otherwise provided, this Agreement has been and is made
solely for the benefit of and shall be binding upon the Company, the Selling
Stockholders, the Underwriters, the Underwriters' directors and officers, any
controlling persons referred to herein, the QIU Indemnified Parties, the
Company's directors and officers who sign the Registration Statement and their
respective successors and assigns, all as and to the extent provided in this
Agreement, and no other person shall acquire or have any right under or by
virtue of this Agreement. The term "successors and assigns" shall not include a
purchaser of any of the Shares from any of the several Underwriters merely
because of such purchase.

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

         This Agreement may be signed in various counterparts which together
shall constitute one and the same instrument.

                              AMENDED AND RESTATED
                        CERTIFICATE OF INCORPORATION OF
                           PARADYNE ACQUISITION CORP.


         The undersigned does hereby certify that the following Amended and
Restated Certificate of Incorporation has been duly approved pursuant to
Sections 242 and 245 of the Delaware General Corporation Law. The original
Certificate of Incorporation was filed with the State of Delaware on June 7,
1996 under the name, "PD Acquisition Corp.", and was amended on June 13, 1996,
changing the corporation's name to "Paradyne Acquisition Corp."

         The Certificate of Incorporation of this corporation is hereby amended
and restated as follows:


                                       I.


         The name of this corporation is Paradyne Networks, Inc.


                                      II.

         The address of the registered office of the corporation in the State of
Delaware is Corporation Trust Center, City of Wilmington, County of New Castle,
and the name of the registered agent of the corporation in the State of Delaware
at such address is the CT Corporation System.

                                      III.

         The purpose of this corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware.

                                      IV.


         A.       This corporation is authorized to issue two classes of stock
to be designated, respectively, "Common Stock" and "Preferred Stock." The total
number of shares which the corporation is authorized to issue is Sixty-Five
Million (65,000,000) shares. Sixty Million (60,000,000) shares shall be Common
Stock, each having a par value of one-tenth of one cent ($.001). Five Million
(5,000,000) shares shall be Preferred Stock, each having a par value of
one-tenth of one cent ($.001). Upon the filing of this Amended and Restated
Certificate of Incorporation, every two (2) outstanding shares of Common Stock
of this corporation shall be combined into one (1) share of Common Stock.


         B.       The Preferred Stock may be issued from time to time in one or
more series. The Board of Directors is hereby authorized, by filing a
certificate (a "Preferred Stock Designation") pursuant to the Delaware General
Corporation Law ("DGCL"), to fix or alter from time to time the designation,
powers, preferences and rights of the shares of each such series and the
qualifications, limitations or restrictions of any wholly unissued series of
Preferred Stock, and to establish from time to time the number of shares
constituting any such series or any of them; and to increase or decrease the
number of shares of any series subsequent to the issuance of shares of that
series, but not below the number of shares of such series then outstanding. In
case the number of shares of any series shall be decreased in accordance with
the foregoing sentence, the shares constituting such decrease shall resume the
status


                                       1.
<PAGE>   2
that they had prior to the adoption of the resolution originally fixing
the number of shares of such series.

                                       V.

         For the management of the business and for the conduct of the affairs
of the corporation, and in further definition, limitation and regulation of the
powers of the corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

         A.       NUMBER AND CLASSIFICATION OF DIRECTORS

                  1.       The management of the business and the conduct of the
affairs of the corporation shall be vested in its Board of Directors. The number
of directors which shall constitute the whole Board of Directors shall be fixed
exclusively by one or more resolutions adopted by the Board of Directors.

                  2.       Subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specified circumstances,
following the closing of the initial public offering pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the "1933
Act"), covering the offer and sale of Common Stock to the public (the "Initial
Public Offering"), the directors shall be divided into three classes designated
as Class I, Class II and Class III, respectively. Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors. At the first annual meeting of stockholders following the closing
of the Initial Public Offering, the term of office of the Class I directors
shall expire and Class I directors shall be elected for a full term of three
years. At the second annual meeting of stockholders following the closing of the
Initial Public Offering, the term of office of the Class II directors shall
expire and Class II directors shall be elected for a full term of three years.
At the third annual meeting of stockholders following the closing of the Initial
Public Offering, the term of office of the Class III directors shall expire and
Class III directors shall be elected for a full term of three years. At each
succeeding annual meeting of stockholders, directors shall be elected for a full
term of three years to succeed the directors of the class whose terms expire at
such annual meeting.

Notwithstanding the foregoing provisions of this section, each director shall
serve until his successor is duly elected and qualified or until his death,
resignation or removal. No decrease in the number of directors constituting the
Board of Directors shall shorten the term of any incumbent director.

                  3.       VACANCIES


                           A.       Subject to the rights of the holders of any
series of Preferred Stock, any vacancies on the Board of Directors resulting
from death, resignation, disqualification, removal or other causes and any newly
created directorships resulting from any increase in the number of directors,
shall, unless the Board of Directors determines by resolution that any such
vacancies or newly created directorships shall be filled by the stockholders,
except as otherwise provided by law, be filled only by the affirmative vote of a
majority of the directors then in office, even though less than a quorum of the
Board of Directors, and not by the stockholders. Any director elected in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the director for which the vacancy was created or occurred and
until such director's successor shall have been elected and qualified.




                                       2.
<PAGE>   3




                           B.       If at the time of filling any vacancy or any
newly created directorship, the directors then in office shall constitute less
than a majority of the whole board (as constituted immediately prior to any such
increase), the Delaware Court of Chancery may, upon application of any
stockholder or stockholders holding at least ten percent (10%) of the total
number of the shares at the time outstanding having the right to vote for such
directors, summarily order an election to be held to fill any such vacancies or
newly created directorships, or to replace the directors chosen by the directors
then in offices as aforesaid, which election shall be governed by Section 211 of
the DGCL.

                  4.       REMOVAL

                           A.       Neither the Board of Directors nor any
individual director may be removed without cause.

                           B.       Subject to any limitation imposed by law,
any individual director or directors may be removed with cause by the holders of
a majority of the voting power of the corporation entitled to vote at an
election of directors

         B.       BYLAWS AND STOCKHOLDER ACTIONS

                  1.       Subject to paragraph (h) of Section 42 of the Bylaws,
the Bylaws may be altered or amended or new Bylaws adopted by the affirmative
vote of at least sixty-six and two-thirds percent (66-2/3%) of the voting power
of all of the then-outstanding shares of the voting stock of the corporation
entitled to vote. The Board of Directors shall also have the power to adopt,
amend, or repeal Bylaws.

                  2.       The directors of the corporation need not be elected
by written ballot unless the Bylaws so provide.

                  3.       No action shall be taken by the stockholders of the
corporation except at an annual or special meeting of stockholders called in
accordance with the Bylaws, and following the closing of the Initial Public
Offering, no action shall be taken by stockholders by written consent.

                  4.       Advance notice of stockholder nominations for the
election of directors and of business to be brought by stockholders before any
meeting of the stockholders of the corporation shall be given in the manner
provided in the Bylaws of the corporation.

                                      VI.

         A.       The liability of the directors for monetary damages shall be
eliminated to the fullest extent under applicable law.



                                       3.
<PAGE>   4

         B.       Any repeal or modification of this Article VI shall be
prospective and shall not affect the rights under this Article VI in effect at
the time of the alleged occurrence of any act or omission to act giving rise to
liability or indemnification.

                                      VII.

         A.       The corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute, except as provided in paragraph
B. of this Article VII, and all rights conferred upon the stockholders herein
are granted subject to this reservation.


         B.       Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser vote
or no vote, but in addition to any affirmative vote of the holders of any
particular class or series of the voting stock of the corporation required by
law, this Certificate of Incorporation or any Preferred Stock Designation, the
affirmative vote of the holders of at least sixty-six and two-thirds percent (66
2/3%) of the voting power of all of the then-outstanding shares of the voting
stock of the corporation, voting together as a single class, shall be required
to alter, amend or repeal Articles.

                                       OF


                           PARADYNE ACQUISITION CORP.


                            (A DELAWARE CORPORATION)


                                    ARTICLE I

                                     OFFICES

         SECTION 1.        REGISTERED OFFICE. The registered office of the
corporation in the State of Delaware shall be in the City of Wilmington County
of New Castle.

         SECTION 2.        OTHER OFFICES. The corporation shall also have and
maintain an office or principal place of business at such place as may be fixed
by the Board of Directors, and may also have offices at such other places, both
within and without the State of Delaware as the Board of Directors may from time
to time determine or the business of the corporation may require.

                                   ARTICLE II

                             STOCKHOLDERS' MEETINGS

         SECTION 3.        PLACE OF MEETINGS. Meetings of the stockholders of
the corporation shall be held at such place, either within or without the State
of Delaware, as may be designated from time to time by the Board of Directors,
or, if not so designated, then at the office of the corporation required to be
maintained pursuant to Section 2 hereof.

         SECTION 4.        ANNUAL MEETINGS.

                  (A)      The annual meeting of the stockholders of the
corporation, for the purpose of election of directors and for such other
business as may lawfully come before it, shall be held on such date and at such
time as may be designated from time to time by the Board of Directors.
Nominations of persons for election to the Board of Directors of the corporation
and the proposal of business to be considered by the stockholders may be made at
an annual meeting of stockholders: (i) pursuant to the corporation's notice of
meeting of stockholders; (ii) by or at the direction of the Board of Directors;
or (iii) by any stockholder of the corporation who was a stockholder of record
at the time of giving of notice provided for in the following paragraph, who is
entitled to vote at the meeting and who complied with the notice procedures set
forth in Section 4.


                  (B)      At an annual meeting of the stockholders, only such
business shall be conducted as shall have been properly brought before the
meeting. For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (iii) of Section 4(a) of
these Bylaws, (i) the stockholder must have given timely notice thereof in




                                       1.
<PAGE>   5


writing to the Secretary of the corporation, (ii) such other business must be a
proper matter for stockholder action under the Delaware General Corporation Law
("DGCL"), (iii) if the stockholder, or the beneficial owner on whose behalf any
such proposal or nomination is made, has provided the corporation with a
Solicitation Notice (as defined in this Section 4(b)), such stockholder or
beneficial owner must, in the case of a proposal, have delivered a proxy
statement and form of proxy to holders of at least the percentage of the
corporation's voting shares required under applicable law to carry any such
proposal, or, in the case of a nomination or nominations, have delivered a proxy
statement and form of proxy to holders of a percentage of the corporation's
voting shares reasonably believed by such stockholder or beneficial owner to be
sufficient to elect the nominee or nominees proposed to be nominated by such
stockholder, and must, in either case, have included in such materials the
Solicitation Notice, and (iv) if no Solicitation Notice relating thereto has
been timely provided pursuant to this section, the stockholder or beneficial
owner proposing such business or nomination must not have solicited a number of
proxies sufficient to have required the delivery of such a Solicitation Notice
under this Section 4. To be timely, a stockholder's notice shall be delivered to
the Secretary at the principal executive offices of the Corporation not later
than the close of business on the ninetieth (90th) day nor earlier than the
close of business on the one hundred twentieth (120th) day prior to the first
anniversary of the preceding year's annual meeting; provided, however, that in
the event that the date of the annual meeting is advanced more than thirty (30)
days prior to or delayed by more than thirty (30) days after the anniversary of
the preceding year's annual meeting, notice by the stockholder to be timely must
be so delivered not earlier than the close of business on the one hundred
twentieth (120th) day prior to such annual meeting and not later than the close
of business on the later of the ninetieth (90th) day prior to such annual
meeting or the tenth (10th) day following the day on which public announcement
of the date of such meeting is first made. In no event shall the public
announcement of an adjournment of an annual meeting commence a new time period
for the giving of a stockholder's notice as described above. Such stockholder's
notice shall set forth: (A) as to each person whom the stockholder proposed to
nominate for election or reelection as a director all information relating to
such person that is required to be disclosed in solicitations of proxies for
election of directors in an election contest, or is otherwise required, in each
case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as
amended (the "1934 Act") and Rule 14a-11 thereunder (including such person's
written consent to being named in the proxy statement as a nominee and to
serving as a director if elected); (B) as to any other business that the
stockholder proposes to bring before the meeting, a brief description of the
business desired to be brought before the meeting, the reasons for conducting
such business at the meeting and any material interest in such business of such
stockholder and the beneficial owner, if any, on whose behalf the proposal is
made; and (C) as to the stockholder giving the notice and the beneficial owner,
if any, on whose behalf the nomination or proposal is made (i) the name and
address of such stockholder, as they appear on the corporation's books, and of
such beneficial owner, (ii) the class and number of shares of the corporation
which are owned beneficially and of record by such stockholder and such
beneficial owner, and (iii) whether either such stockholder or beneficial owner
intends to deliver a proxy statement and form of proxy to holders of, in the
case of the proposal, at least the percentage of the corporation's voting shares
required under applicable law to carry the proposal or, in the case of a
nomination or nominations, a sufficient number of holders of the corporation's
voting shares to elect such nominee or nominees (an affirmative statement of
such intent, a "Solicitation Notice").

                  (C)      Notwithstanding anything in the second sentence of
Section 4(b) of these Bylaws to the contrary, in the event that the number of
directors to be elected to the Board of Directors of the Corporation is
increased and there is no public announcement naming all of the nominees for
director or specifying the size of the increased Board of Directors made by the
corporation at least one hundred (100) days prior to the first anniversary of
the preceding year's annual meeting, a stockholder's notice required by this
Section 4 shall also be considered timely, but only with respect to nominees for
any new positions created by such increase, if it shall be delivered to the
Secretary at the principal executive offices of the corporation not later than
the close of business on the tenth (10th) day following the day on which such
public announcement is first made by the corporation.


                  (D)      Only such persons who are nominated in accordance
with the procedures set forth in this Section 4 shall be eligible to serve as
directors and only such business shall be conducted at a meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Section 4. Except as otherwise provided by law, the Chairman
of the meeting shall have the power and duty to determine whether a nomination
or any business proposed to be brought before the meeting was made, or proposed,
as the case may be, in accordance with the procedures set forth in these Bylaws
and, if any proposed nomination or business is not in compliance with these
Bylaws, to declare that such defective proposal or nomination shall not be
presented for stockholder action at the meeting and shall be disregarded.

                  (E)      Notwithstanding the foregoing provisions of this
Section 4, in order to include information with respect to a stockholder
proposal in the proxy statement and form of proxy for a stockholder's meeting,
stockholders must provide notice as required by the regulations promulgated
under the 1934 Act. Nothing in these Bylaws shall be deemed to affect any rights
of stockholders to request inclusion of proposals in the corporation proxy
statement pursuant to Rule 14a-8 under the 1934 Act.

                  (F)      For purposes of this Section 4, "public announcement"
shall mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable national news service or in a document publicly
filed by the corporation with the Securities and Exchange Commission pursuant to
Section 13, 14 or 15(d) of the 1934 Act.

         SECTION 5.        SPECIAL MEETINGS.

                  (A)      Special meetings of the stockholders of the
corporation may be called, for any purpose or purposes, by (i) the Chairman of
the Board of Directors, (ii) the Chief Executive Officer, (iii) the Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized directors (whether or not there exist any vacancies in previously
authorized directorships at the time any such resolution is presented to the
Board of Directors for adoption) or (iv) holders of the shares entitled to cast
not less than fifty percent (50%) of the votes at the meeting.


                  (B)      If a special meeting is properly called by any person
or persons other than the Board of Directors, the request shall be in writing,
specifying the general nature of the business proposed to be transacted, and
shall be delivered personally or sent by registered mail or




                                       3.
<PAGE>   7


by telegraphic or other facsimile transmission to the Chairman of the Board of
Directors, the Chief Executive Officer, or the Secretary of the corporation. No
business may be transacted at such special meeting otherwise than specified in
such notice. The Board of Directors shall determine the time and place of such
special meeting, which shall be held not less than thirty-five (35) nor more
than one hundred twenty (120) days after the date of the receipt of the request.
Upon determination of the time and place of the meeting, the officer receiving
the request shall cause notice to be given to the stockholders entitled to vote,
in accordance with the provisions of Section 6 of these Bylaws. If the notice is
not given within one hundred (100) days after the receipt of the request, the
person or persons properly requesting the meeting may set the time and place of
the meeting and give the notice. Nothing contained in this paragraph (b) shall
be construed as limiting, fixing, or affecting the time when a meeting of
stockholders called by action of the Board of Directors may be held.


                  (C)      Nominations of persons for election to the Board of
Directors may be made at a special meeting of stockholders at which directors
are to be elected pursuant to the corporation's notice of meeting (i) by or at
the direction of the Board of Directors or (ii) by any stockholder of the
corporation who is a stockholder of record at the time of giving notice provided
for in these Bylaws who shall be entitled to vote at the meeting and who
complies with the notice procedures set forth in this Section 5(c). In the event
the corporation calls a special meeting of stockholders for the purpose of
electing one or more directors to the Board of Directors, any such stockholder
may nominate a person or persons (as the case may be), for election to such
position(s) as specified in the corporation's notice of meeting, if the
stockholder's notice required by Section 4(b) of these Bylaws shall be delivered
to the Secretary at the principal executive offices of the corporation not
earlier than the close of business on the one hundred twentieth (120th) day
prior to such special meeting and not later than the close of business on the
later of the ninetieth (90th) day prior to such meeting or the tenth (10th) day
following the day on which public announcement is first made of the date of the
special meeting and of the nominees proposed by the Board of Directors to be
elected at such meeting. In no event shall the public announcement of an
adjournment of a special meeting commence a new time period for the giving of a
stockholder's notice as described above.


         SECTION 6.        NOTICE OF MEETINGS. Except as otherwise provided by
law or the Certificate of Incorporation, written notice of each meeting of
stockholders shall be given not less than ten (10) nor more than sixty (60) days
before the date of the meeting to each stockholder entitled to vote at such
meeting, such notice to specify the place, date and hour and purpose or purposes
of the meeting. Notice of the time, place and purpose of any meeting of
stockholders may be waived in writing, signed by the person entitled to notice
thereof, either before or after such meeting, and will be waived by any
stockholder by his attendance thereat in person or by proxy, except when the
stockholder attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened. Any stockholder so waiving notice of such
meeting shall be bound by the proceedings of any such meeting in all respects as
if due notice thereof had been given.



         SECTION 7.        QUORUM. At all meetings of stockholders, except where
otherwise provided by statute or by the Certificate of Incorporation, or by
these Bylaws, the presence, in person or by proxy duly authorized, of the
holders of a majority of the outstanding shares of stock




                                       4.
<PAGE>   8


entitled to vote shall constitute a quorum for the transaction of business. In
the absence of a quorum, any meeting of stockholders may be adjourned, from time
to time, either by the chairman of the meeting or by vote of the holders of a
majority of the shares represented thereat, but no other business shall be
transacted at such meeting. The stockholders present at a duly called or
convened meeting, at which a quorum is present, may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum. Except as otherwise provided by
statute, the Certificate of Incorporation or these Bylaws, in all matters other
than the election of directors, the affirmative vote of the majority of shares
present in person or represented by proxy at the meeting and entitled to vote on
the subject matter shall be the act of the stockholders. Except as otherwise
provided by statute, the Certificate of Incorporation or these Bylaws, directors
shall be elected by a plurality of the votes of the shares present in person or
represented by proxy at the meeting and entitled to vote on the election of
directors. Where a separate vote by a class or classes or series is required,
except where otherwise provided by the statute or by the Certificate of
Incorporation or these Bylaws, a majority of the outstanding shares of such
class or classes or series, present in person or represented by proxy, shall
constitute a quorum entitled to take action with respect to that vote on that
matter and, except where otherwise provided by the statute or by the Certificate
of Incorporation or these Bylaws, the affirmative vote of the majority
(plurality, in the case of the election of directors) of the votes cast by the
holders of shares of such class or classes or series shall be the act of such
class or classes or series.


         SECTION 8.        ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS. Any
meeting of stockholders, whether annual or special, may be adjourned from time
to time either by the chairman of the meeting or by the vote of a majority of
the shares casting votes. When a meeting is adjourned to another time or place,
notice need not be given of the adjourned meeting if the time and place thereof
are announced at the meeting at which the adjournment is taken. At the adjourned
meeting, the corporation may transact any business which might have been
transacted at the original meeting. If the adjournment is for more than thirty
(30) days or if after the adjournment a new record date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.

         SECTION 9.        VOTING RIGHTS. For the purpose of determining those
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the stock
records of the corporation on the record date, as provided in Section 11 of
these Bylaws, shall be entitled to vote at any meeting of stockholders. Every
person entitled to vote shall have the right to do so either in person or by an
agent or agents authorized by a proxy granted in accordance with Delaware law.
An agent so appointed need not be a stockholder. No proxy shall be voted after
three (3) years from its date of creation unless the proxy provides for a longer
period.


         SECTION 10.       JOINT OWNERS OF STOCK. If shares or other securities
having voting power stand of record in the names of two (2) or more persons,
whether fiduciaries, members of a partnership, joint tenants, tenants in common,
tenants by the entirety, or otherwise, or if two (2) or more persons have the
same fiduciary relationship respecting the same shares, unless the Secretary is
given written notice to the contrary and is furnished with a copy of the
instrument or order appointing them or creating the relationship wherein it is
so provided, their acts with respect




                                       5.
<PAGE>   9


to voting shall have the following effect: (a) if only one (1) votes, his act
binds all; (b) if more than one (1) votes, the act of the majority so voting
binds all; (c) if more than one (1) votes, but the vote is evenly split on any
particular matter, each faction may vote the securities in question
proportionally, or may apply to the Delaware Court of Chancery for relief as
provided in the DGCL, Section 217(b). If the instrument filed with the Secretary
shows that any such tenancy is held in unequal interests, a majority or
even-split for the purpose of subsection (c) shall be a majority or even-split
in interest.


         SECTION 11.       LIST OF STOCKHOLDERS. The Secretary shall prepare and
make, at least ten (10) days before every meeting of stockholders, a complete
list of the stockholders entitled to vote at said meeting, arranged in
alphabetical order, showing the address of each stockholder and the number of
shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not
specified, at the place where the meeting is to be held. The list shall be
produced and kept at the time and place of meeting during the whole time thereof
and may be inspected by any stockholder who is present.

         SECTION 12.       ACTION WITHOUT MEETING.

                  (A)      Unless otherwise provided in the Certificate of
Incorporation, any action required by statute to be taken at any annual or
special meeting of the stockholders, or any action which may be taken at any
annual or special meeting of the stockholders, may be taken without a meeting,
without prior notice and without a vote, if a consent in writing, setting forth
the action so taken, shall be signed by the holders of outstanding stock having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted.

                  (B)      Every written consent shall bear the date of
signature of each stockholder who signs the consent, and no written consent
shall be effective to take the corporate action referred to therein unless,
within sixty (60) days of the earliest dated consent delivered to the
corporation in the manner herein required, written consents signed by a
sufficient number of stockholders to take action are delivered to the
corporation by delivery to its registered office in the State of Delaware, its
principal place of business or an officer or agent of the corporation having
custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to a corporation's registered office shall be by hand or
by certified or registered mail, return receipt requested.


                  (C)      Prompt notice of the taking of the corporate action
without a meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing. If the action which is consented
to is such as would have required the filing of a certificate under any section
of the DGCL if such action had been voted on by stockholders at a meeting
thereof, then the certificate filed under such section shall state, in lieu of
any statement required by such section concerning any vote of stockholders, that
written consent has been given in accordance with Section 228 of the DGCL.





                                       6.

<PAGE>   10

                  (D)      Notwithstanding the foregoing, no such action by
written consent may be taken following the closing of the initial public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended (the "1933 Act"), covering the offer and sale of Common
Stock of the corporation (the "Initial Public Offering").

         SECTION 13.       ORGANIZATION.

                  (A)      At every meeting of stockholders, the Chairman of the
Board of Directors, or, if a Chairman has not been appointed or is absent, the
President, or, if the President is absent, a chairman of the meeting chosen by a
majority in interest of the stockholders entitled to vote, present in person or
by proxy, shall act as chairman. The Secretary, or, in his absence, an Assistant
Secretary directed to do so by the President, shall act as secretary of the
meeting.

                  (B)      The Board of Directors of the corporation shall be
entitled to make such rules or regulations for the conduct of meetings of
stockholders as it shall deem necessary, appropriate or convenient. Subject to
such rules and regulations of the Board of Directors, if any, the chairman of
the meeting shall have the right and authority to prescribe such rules,
regulations and procedures and to do all such acts as, in the judgment of such
chairman, are necessary, appropriate or convenient for the proper conduct of the
meeting, including, without limitation, establishing an agenda or order of
business for the meeting, rules and procedures for maintaining order at the
meeting and the safety of those present, limitations on participation in such
meeting to stockholders of record of the corporation and their duly authorized
and constituted proxies and such other persons as the chairman shall permit,
restrictions on entry to the meeting after the time fixed for the commencement
thereof, limitations on the time allotted to questions or comments by
participants and regulation of the opening and closing of the polls for
balloting on matters which are to be voted on by ballot. Unless and to the
extent determined by the Board of Directors or the chairman of the meeting,
meetings of stockholders shall not be required to be held in accordance with
rules of parliamentary procedure.

                                  ARTICLE III

                                    DIRECTORS


         SECTION 14.       NUMBER AND TERM OF OFFICE. The authorized number of
directors of the corporation shall be fixed in accordance with the Certificate
of Incorporation. Directors need not be stockholders unless so required by the
Certificate of Incorporation. If for any cause, the directors shall not have
been elected at an annual meeting, they may be elected as soon thereafter as
convenient at a special meeting of the stockholders called for that purpose in
the manner provided in these Bylaws.


         SECTION 15.       POWERS. The powers of the corporation shall be
exercised, its business conducted and its property controlled by the Board of
Directors, except as may be otherwise provided by statute or by the Certificate
of Incorporation.

         SECTION 16.       CLASSES OF DIRECTORS. Subject to the rights of the
holders of any series of Preferred Stock to elect additional directors under
specified circumstances, following the closing




                                       7.

<PAGE>   11

of the Initial Public Offering, the directors shall be divided into three
classes designated as Class I, Class II and Class III, respectively. Directors
shall be assigned to each class in accordance with a resolution or resolutions
adopted by the Board of Directors. At the first annual meeting of stockholders
following the closing of the Initial Public Offering, the term of office of the
Class I directors shall expire and Class I directors shall be elected for a full
term of three years. At the second annual meeting of stockholders following the
closing of the Initial Public Offering, the term of office of the Class II
directors shall expire and Class II directors shall be elected for a full term
of three years. At the third annual meeting of stockholders following the
closing of the Initial Public Offering, the term of office of the Class III
directors shall expire and Class III directors shall be elected for a full term
of three years. At each succeeding annual meeting of stockholders, directors
shall be elected for a full term of three years to succeed the directors of the
class whose terms expire at such annual meeting.

Notwithstanding the foregoing provisions of this section, each director shall
serve until his successor is duly elected and qualified or until his death,
resignation or removal. No decrease in the number of directors constituting the
Board of Directors shall shorten the term of any incumbent director.

         SECTION 17.       VACANCIES.

                  (A)      Unless otherwise provided in the Certificate of
Incorporation, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors shall,
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by stockholders, be filled only
by the affirmative vote of a majority of the directors then in office, even
though less than a quorum of the Board of Directors. Any director elected in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the director for which the vacancy was created or occurred and
until such director's successor shall have been elected and qualified. A vacancy
in the Board of Directors shall be deemed to exist under this Section 17 in the
case of the death, removal or resignation of any director.


                  (B)      If at the time of filling any vacancy or any newly
created directorship, the directors then in office shall constitute less than a
majority of the whole board (as constituted immediately prior to any such
increase), the Delaware Court of Chancery may, upon application of any
stockholder or stockholders holding at least ten percent (10%) of the total
number of the shares at the time outstanding having the right to vote for such
directors, summarily order an election to be held to fill any such vacancies or
newly created directorships, or to replace the directors chosen by the directors
then in offices as aforesaid, which election shall be governed by Section 211 of
the DGCL.



         SECTION 18.       RESIGNATION. Any director may resign at any time by
delivering his written resignation to the Secretary, such resignation to specify
whether it will be effective at a particular time, upon receipt by the Secretary
or at the pleasure of the Board of Directors. If no such specification is made,
it shall be deemed effective at the pleasure of the Board of Directors. When one
or more directors shall resign from the Board of Directors, effective at a
future date, a




                                       8.
<PAGE>   12


majority of the directors then in office, including those who have so resigned,
shall have power to fill such vacancy or vacancies, the vote thereon to take

any meeting of the Board of Directors, or any committee thereof, however called

Board of Directors. The Executive Committee, to the extent permitted by law and
provided in the resolution of the Board of Directors shall have and may exercise
all the powers and authority of the Board of Directors in the management of the
business and affairs of the corporation, and may authorize the seal of the
corporation to be affixed to all papers which may require it; but no such
committee shall have the power or authority in reference to (i) approving or
adopting, or recommending to the stockholders, any action or matter expressly
required by the DGCL to be submitted to stockholders for approval, or (ii)

such duties as may be prescribed by the resolution or resolutions creating such
committees, but in no event shall any such committee have the powers denied to

                  (C)      TERM. Each member of a committee of the Board of
Directors shall serve a term on the committee coexistent with such member's term
on the Board of Directors. The Board of Directors, subject to any requirements
of any outstanding series of preferred Stock and the provisions of subsections
(a) or (b) of this Bylaw, may at any time increase or decrease the number of
members of a committee or terminate the existence of a committee. The membership
of a committee member shall terminate on the date of his death or voluntary
resignation from the committee or from the Board of Directors. The Board of
Directors may at any time for any reason remove any individual committee member
and the Board of Directors may fill any committee vacancy created by death,
resignation, removal or increase in the number of members of the committee. The
Board of Directors may designate one or more directors as alternate members of
any committee, who may replace any absent or disqualified member at any meeting
of the committee, and, in addition, in the absence or disqualification of any
member of a committee, the member or members thereof present at any meeting and
not disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.


                  (D)      MEETINGS. Unless the Board of Directors shall
otherwise provide, regular meetings of the Executive Committee or any other
committee appointed pursuant to this Section 24 shall be held at such times and
places as are determined by the Board of Directors, or by any such committee,
and when notice thereof has been given to each member of such committee, no
further notice of such regular meetings need be given thereafter. Special
meetings of any such committee may be held at any place which has been
determined from time to time by such committee, and may be called by any
director who is a member of such committee, upon written notice to the members
of such committee of the time and place of such special meeting given in the
manner provided for the giving of written notice to members of the Board of
Directors of the time and place of special meetings of the Board of Directors.
Notice of any special meeting of any committee may be waived in writing at any
time before or after the meeting




                                      11.

and will be waived by any director by attendance thereat, except when the
director attends such special meeting for the express purpose of objecting, at
the beginning of the meeting, to the transaction of any business because the
meeting is not lawfully called or convened. A majority of the authorized number
of members of any such committee shall constitute a quorum for the transaction
of business, and the act of a majority of those present at any meeting at which
a quorum is present shall be the act of such committee.


         SECTION 25.       ORGANIZATION. At every meeting of the directors, the
Chairman of the Board of Directors, or, if a Chairman has not been appointed or
is absent, the President (if a director), or if the President is absent, the
most senior Vice President (if a director), or, in the absence of any such
person, a chairman of the meeting chosen by a majority of the directors present,

    EXECUTION OF CORPORATE INSTRUMENTS AND VOTING OF SECURITIES OWNED BY THE
                                  CORPORATION

         SECTION 31.       EXECUTION OF CORPORATE INSTRUMENTS. The Board of
Directors may, in its discretion, determine the method and designate the
signatory officer or officers, or other person or persons, to execute on behalf
of the corporation any corporate instrument or document, or to sign on behalf of

                                 SHARES OF STOCK

         SECTION 33.       FORM AND EXECUTION OF CERTIFICATES. Certificates for
the shares of stock of the corporation shall be in such form as is consistent
with the Certificate of Incorporation and applicable law. Every holder of stock

name of the corporation by the Chairman of the Board of Directors, or the
President or any Vice President and by the Treasurer or Assistant Treasurer or
the Secretary or Assistant Secretary, certifying the number of shares owned by
him in the corporation. Any or all of the signatures on the certificate may be
facsimiles. In case any officer, transfer agent, or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent, or registrar before such certificate is
issued, it may be issued with the same effect as if he were such officer,
transfer agent, or registrar at the date of issue. Each certificate shall state
upon the face or back thereof, in full or in summary, all of the powers,
designations, preferences, and rights, and the limitations or restrictions of
the shares authorized to be issued or shall, except as otherwise required by
law, set forth on the face or back a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, designations,
preferences and relative, participating, optional, or other special rights of
each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights. Within a reasonable time after
the issuance or transfer of uncertificated stock, the corporation shall send to
the registered owner thereof a written notice containing the information
required to be set forth or stated on certificates pursuant to this section or
otherwise required by law or with respect to this section a statement that the
corporation will furnish without charge to each stockholder who so requests the
powers, designations, preferences and relative participating, optional or other
special rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights. Except as
otherwise expressly provided by law, the rights and obligations of the holders
of certificates representing stock of the same class and series shall be
identical.


         SECTION 34.       LOST CERTIFICATES. A new certificate or certificates
shall be issued in place of any certificate or certificates theretofore issued
by the corporation alleged to have been lost, stolen, or destroyed, upon the
making of an affidavit of that fact by the person claiming the certificate of
stock to be lost, stolen, or destroyed. The corporation may require, as a
condition precedent to the issuance of a new certificate or certificates, the
owner of such lost, stolen, or destroyed certificate or certificates, or his
legal representative, to agree to indemnify the corporation in such manner as it
shall require or to give the corporation a surety bond in such form and amount
as it may direct as indemnity against any claim that may be made against the
corporation with respect to the certificate alleged to have been lost, stolen,
or destroyed.


         SECTION 35.       TRANSFERS.

                  (A)      Transfers of record of shares of stock of the

                  (B)      The corporation shall have power to enter into and
perform any agreement with any number of stockholders of any one or more classes
of stock of the corporation to restrict the transfer of shares of stock of the
corporation of any one or more classes owned by such stockholders in any manner
not prohibited by the DGCL.

         SECTION 36.       FIXING RECORD DATES.

                  (A)      In order that the corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, the Board of Directors may fix, in advance, a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted by the Board of Directors, and which record
date shall, subject to applicable law, not be more than sixty (60) nor less than
ten (10) days before the date of such meeting. If no record date is fixed by the
Board of Directors, the record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held. A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting; provided, however, that the Board of Directors may fix a new
record date for the adjourned meeting.


                  (B)      Prior to the Initial Public Offering, in order that
the corporation may determine the stockholders entitled to consent to corporate
action in writing without a meeting, the Board of Directors may fix a record
date, which record date shall not precede the date upon which the resolution
fixing the record date is adopted by the Board of Directors, and which date
shall not be more than ten (10) days after the date upon which the resolution
fixing the record date is adopted by the Board of Directors. Any stockholder of
record seeking to have the stockholders authorize or take corporate action by
written consent shall, by written notice to the Secretary, request the Board of
Directors to fix a record date. The Board of Directors shall promptly, but in
all events within ten (10) days after the date on which such a request is
received, adopt a resolution fixing the record date. If no record date has been
fixed by the Board of Directors within ten (10) days of the date on which such a
request is received, the record date for determining stockholders entitled to
consent to corporate action in writing without a meeting, when no prior action
by the Board of Directors is required by applicable law, shall be the first date
on which a signed written consent setting forth the action taken or proposed to
be taken is delivered to the corporation by delivery to its registered office in
the State of Delaware, its principal place of business or an officer or agent of
the corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Delivery made to the corporation's registered office
shall be by hand or by certified or registered mail, return receipt requested.
If no record date has been fixed by the Board of Directors and prior action by
the Board of Directors is required by law, the record date for determining
stockholders entitled to consent to corporate action in writing without a
meeting shall be at the close of business on the day on which the Board of
Directors adopts the resolution taking such prior action.



                  (C)      In order that the corporation may determine the
stockholders entitled to receive payment of any dividend or other distribution
or allotment of any rights or the stockholders entitled to exercise any rights
in respect of any change, conversion or exchange of




                                      16.
<PAGE>   20


stock, or for the purpose of any other lawful action, the Board of Directors may
fix, in advance, a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted, and which record
date shall be not more than sixty (60) days prior to such action. If no record
date is fixed, the record date for determining stockholders for any such purpose
shall be at the close of business on the day on which the Board of Directors
adopts the resolution relating thereto.


         SECTION 37.       REGISTERED STOCKHOLDERS. The corporation shall be
entitled to recognize the exclusive right of a person registered on its books as
the owner of shares to receive dividends, and to vote as such owner, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of any other person whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                  ARTICLE VII

                       OTHER SECURITIES OF THE CORPORATION


         SECTION 38.       EXECUTION OF OTHER SECURITIES. All bonds, debentures
and other corporate securities of the corporation, other than stock certificates
(covered in Section 33), may be signed by the Chairman of the Board of
Directors, the President or any Vice President, or such other person as may be
authorized by the Board of Directors, and the corporate seal impressed thereon
or a facsimile of such seal imprinted thereon and attested by the signature of
the Secretary or an Assistant Secretary, or the Chief Financial Officer or
Treasurer or an Assistant Treasurer; provided, however, that where any such
bond, debenture or other corporate security shall be authenticated by the manual
signature, or where permissible facsimile signature, of a trustee under an
indenture pursuant to which such bond, debenture or other corporate security
shall be issued, the signatures of the persons signing and attesting the
corporate seal on such bond, debenture or other corporate security may be the
imprinted facsimile of the signatures of such persons. Interest coupons
appertaining to any such bond, debenture or other corporate security,
authenticated by a trustee as aforesaid, shall be signed by the Treasurer or an
Assistant Treasurer of the corporation or such other person as may be authorized
by the Board of Directors, or bear imprinted thereon the facsimile signature of
such person. In case any officer who shall have signed or attested any bond,
debenture or other corporate security, or whose facsimile signature shall appear
thereon or on any such interest coupon, shall have ceased to be such officer
before the bond, debenture or other corporate security so signed or attested
shall have been delivered, such bond, debenture or other corporate security
nevertheless may be adopted by the corporation and issued and delivered as
though the person who signed the same or whose facsimile signature shall have
been used thereon had not ceased to be such officer of the corporation.


                                  ARTICLE VIII

                                    DIVIDENDS

         SECTION 40.       DIVIDEND RESERVE. Before payment of any dividend,

property of the corporation, or for such other purpose as the Board of Directors
shall think conducive to the interests of the corporation, and the Board of
Directors may modify or abolish any such reserve in the manner in which it was
created.

                                   ARTICLE X

                                 INDEMNIFICATION

         SECTION 42.       INDEMNIFICATION OF DIRECTORS, EXECUTIVE OFFICERS,
OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS.


                  (A)      DIRECTORS. The corporation shall indemnify its
directors to the fullest extent not prohibited by the DGCL or any other
applicable law; provided, however, that the corporation may modify the extent of
such indemnification by individual contracts with its directors; and, provided,
further, that the corporation shall not be required to indemnify any director in
connection with any proceeding (or part thereof) initiated by such person unless
(i) such indemnification is expressly required to be made by law, (ii) the
proceeding was authorized by the Board of Directors of the corporation, (iii)
such indemnification is provided by the corporation, in its sole discretion,
pursuant to the powers vested in the corporation under the DGCL or any other
applicable law or (iv) such indemnification is required to be made under
subsection (d).


                  (B)      OFFICERS, EMPLOYEES AND OTHER AGENTS. The corporation
shall have power to indemnify its employees and other agents as set forth in the
DGCL or any other applicable law. The Board of Directors shall have the power to
delegate the determination of whether indemnification shall be given to any such
person to such officers or other persons as the Board of Directors shall
determine.

                  (C)      EXPENSES. The corporation shall advance to any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he is or was a
director, of the corporation, or is or was serving at the request of the
corporation as a director or executive officer of another corporation,
partnership, joint venture, trust or other




                                      18.

<PAGE>   22

enterprise, prior to the final disposition of the proceeding, promptly following
request therefor, all expenses incurred by any director in connection with such
proceeding upon receipt of an undertaking by or on behalf of such person to
repay said amounts if it should be determined ultimately that such person is not
entitled to be indemnified under this Section 42 or otherwise.

         Notwithstanding the foregoing, unless otherwise determined pursuant to
paragraph (e) of this Section 42, no advance shall be made by the corporation to
an officer of the corporation (except by reason of the fact that such officer is
or was a director of the corporation in which event this paragraph shall not
apply) in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, if a determination is reasonably and promptly
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to the proceeding, or (ii) if such quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, that the facts known
to the decision-making party at the time such determination is made demonstrate
clearly and convincingly that such person acted in bad faith or in a manner that
such person did not believe to be in or not opposed to the best interests of the
corporation.


                  (D)      ENFORCEMENT. Without the necessity of entering into
an express contract, all rights to indemnification and advances to directors
under this Bylaw shall be deemed to be contractual rights and be effective to
the same extent and as if provided for in a contract between the corporation and
the director. Any right to indemnification or advances granted by this Section
42 to a director shall be enforceable by or on behalf of the person holding such
right in any court of competent jurisdiction if (i) the claim for
indemnification or advances is denied, in whole or in part, or (ii) no
disposition of such claim is made within ninety (90) days of request therefor.
The claimant in such enforcement action, if successful in whole or in part,
shall be entitled to be paid also the expense of prosecuting his claim. In
connection with any claim for indemnification, the corporation shall be entitled
to raise as a defense to any such action that the claimant has not met the
standards of conduct that make it permissible under the DGCL or any other
applicable law for the corporation to indemnify the claimant for the amount
claimed. Neither the failure of the corporation (including its Board of
Directors, independent legal counsel or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he has met the applicable
standard of conduct set forth in the DGCL or any other applicable law, nor an
actual determination by the corporation (including its Board of Directors,
independent legal counsel or its stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that claimant has not met the applicable standard of conduct.


                  (E)      NON-EXCLUSIVITY OF RIGHTS. The rights conferred on
any person by this Bylaw shall not be exclusive of any other right which such
person may have or hereafter acquire under any applicable statute, provision of
the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding office. The corporation is
specifically authorized to enter into individual contracts with any or all of
its directors, officers, employees or agents respecting indemnification and
advances, to the fullest extent not prohibited by the Delaware General
Corporation Law, or by any other applicable law.

<PAGE>   23

                  (F)      SURVIVAL OF RIGHTS. The rights conferred on any
person by this Bylaw shall continue as to a person who has ceased to be a
director, officer, employee or other agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

                  (G)      INSURANCE. To the fullest extent permitted by the
DGCL or any other applicable law, the corporation, upon approval by the Board of
Directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this Section 42.

                  (H)      AMENDMENTS. Any repeal or modification of this
Section 42 shall only be prospective and shall not affect the rights under this
Bylaw in effect at the time of the alleged occurrence of any action or omission
to act that is the cause of any proceeding against any agent of the corporation.

                  (I)      SAVING CLAUSE. If this Bylaw or any portion hereof
shall be invalidated on any ground by any court of competent jurisdiction, then
the corporation shall nevertheless indemnify each director to the full extent
not prohibited by any applicable portion of this Section 42 that shall not have
been invalidated, or by any other applicable law. If this Section 42 shall be
invalid due to the application of the indemnification provisions of another
jurisdiction, then the corporation shall indemnify each director and to the full
to the full extent under any other applicable law.

                  (J)      CERTAIN DEFINITIONS. For the purposes of this Bylaw,
the following definitions shall apply:

                           (1)      The term "proceeding" shall be broadly
construed and shall include, without limitation, the investigation, preparation,
prosecution, defense, settlement, arbitration and appeal of, and the giving of
testimony in, any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative.


                           (2)      The term "expenses" shall be broadly
construed and shall include, without limitation, court costs, attorneys' fees,
witness fees, fines, amounts paid in settlement or judgment and any other costs
and expenses of any nature or kind incurred in connection with any proceeding.


                           (3)      The term the "corporation" shall include, in
addition to the resulting corporation, any constituent corporation (including
any constituent of a constituent) absorbed in a consolidation or merger which,
if its separate existence had continued, would have had power and authority to
indemnify its directors, officers, and employees or agents, so that any person
who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, shall stand in the same position under
the provisions of this Section 42 with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

                           (4)      References to a "director," "executive
officer," "officer," "employee," or "agent" of the corporation shall include,
without limitation, situations where such




                                      20.

director, executive officer, officer, employee, trustee or agent of another
corporation, partnership, joint venture, trust or other enterprise.

                           (5)      References to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the corporation" as referred to in this Section
42.

                                   ARTICLE XI

                                     NOTICES

         SECTION 43.       NOTICES.

                  (A)      NOTICE TO STOCKHOLDERS. Whenever, under any
provisions of these Bylaws, notice is required to be given to any stockholder,
it shall be given in writing, timely and duly deposited in the United States
mail, postage prepaid, and addressed to his last known post office address as
shown by the stock record of the corporation or its transfer agent.


                  (B)      NOTICE TO DIRECTORS. Any notice required to be given
to any director may be given by the method stated in subsection (a), or by
overnight delivery service, facsimile, telex or telegram, except that such
notice other than one which is delivered personally shall be sent to such
address as such director shall have filed in writing with the Secretary, or, in
the absence of such filing, to the last known post office address of such
director.


                  (C)      AFFIDAVIT OF MAILING. An affidavit of mailing,
executed by a duly authorized and competent employee of the corporation or its
transfer agent appointed with respect to the class of stock affected, specifying
the name and address or the names and addresses of the stockholder or
stockholders, or director or directors, to whom any such notice or notices was
or were given, and the time and method of giving the same, shall in the absence
of fraud, be prima facie evidence of the facts therein contained.

                  (D)      TIME NOTICES DEEMED GIVEN. All notices given by mail
or by overnight delivery service, as above provided, shall be deemed to have
been given as at the time of mailing, and all notices given by facsimile, telex
or telegram shall be deemed to have been given as of the sending time recorded
at time of transmission.

                  (E)      METHODS OF NOTICE. It shall not be necessary that the
same method of giving notice be employed in respect of all directors, but one
permissible method may be




                                      21.

<PAGE>   25

employed in respect of any one or more, and any other permissible method or
methods may be employed in respect of any other or others.

                  (F)      FAILURE TO RECEIVE NOTICE. The period or limitation
of time within which any stockholder may exercise any option or right, or enjoy
any privilege or benefit, or be required to act, or within which any director
may exercise any power or right, or enjoy any privilege, pursuant to any notice
sent him in the manner above provided, shall not be affected or extended in any
manner by the failure of such stockholder or such director to receive such
notice.

                  (G)      NOTICE TO PERSON WITH WHOM COMMUNICATION IS UNLAWFUL.
Whenever notice is required to be given, under any provision of law or of the
Certificate of Incorporation or Bylaws of the corporation, to any person with
whom communication is unlawful, the giving of such notice to such person shall
not be required and there shall be no duty to apply to any governmental
authority or agency for a license or permit to give such notice to such person.
Any action or meeting which shall be taken or held without notice to any such
person with whom communication is unlawful shall have the same force and effect
as if such notice had been duly given. In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the DGCL, the certificate shall state, if such is the fact and if
notice is required, that notice was given to all persons entitled to receive
notice except such persons with whom communication is unlawful.


                  (H)      NOTICE TO PERSON WITH UNDELIVERABLE ADDRESS. Whenever
notice is required to be given, under any provision of law or the Certificate of
Incorporation or Bylaws of the corporation, to any stockholder to whom (i)
notice of two consecutive annual meetings, and all notices of meetings or of the
taking of action by written consent without a meeting to such person during the
period between such two consecutive annual meetings, or (ii) all, and at least
two, payments (if sent by first class mail) of dividends or interest on
securities during a twelve-month period, have been mailed addressed to such
person at his address as shown on the records of the corporation and have been
returned undeliverable, the giving of such notice to such person shall not be
required. Any action or meeting which shall be taken or held without notice to
such person shall have the same force and effect as if such notice had been duly
given. If any such person shall deliver to the corporation a written notice
setting forth his then current address, the requirement that notice be given to
such person shall be reinstated. In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the DGCL, the certificate need not state that notice was not given
to persons to whom notice was not required to be given pursuant to this
paragraph.


                                  ARTICLE XII

                                   AMENDMENTS

         SECTION 44.       AMENDMENTS. Subject to paragraph (h) of Section 42 of
the Bylaws, the Bylaws may be altered or amended or new Bylaws adopted by the
affirmative vote of at least sixty-six and two-thirds percent (66-2/3%) of the
voting power of all of the then-outstanding shares of the voting stock of the
corporation entitled to vote. The Board of Directors shall also have the power
to adopt, amend, or repeal Bylaws.

                                LOANS TO OFFICERS

or guarantee any obligation of, or otherwise assist any officer or other
employee of the corporation or of its subsidiaries, including any officer or
employee who is a Director of the corporation or its subsidiaries, whenever, in
the judgment of the Board of Directors, such loan, guarantee or assistance may
reasonably be expected to benefit the corporation. The loan, guarantee or other
assistance may be with or without interest and may be unsecured, or secured in
such manner as the Board of Directors shall approve, including, without
limitation, a pledge of shares of stock of the corporation. Nothing in these
Bylaws shall be deemed to deny, limit or restrict the powers of guaranty or
warranty of the corporation at common law or under any statute.

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection
with the filing by Paradyne Networks, Inc. (the "Company") of a Registration
Statement on Form S-1 (the "Registration Statement") with the Securities and
Exchange Commission (the "Commission") covering the underwritten public offering
of up to 6,900,000 shares of common stock, including 4,000,000 shares to be sold
by the Company (the "Company Shares"), 900,000 shares for which the Underwriters
have been granted an over-allotment option, and 2,000,000 shares to be sold by
certain selling stockholders (the "Selling Stockholder Shares") (collectively,
the "Common Stock").

In connection with this opinion, we have (i) examined and relied upon the
Registration Statement and related Prospectus, the Company's Amended and
Restated Certificate of Incorporation and Bylaws and the originals or copies
certified to our satisfaction of such records, documents, certificates,
memoranda and other instruments as in our judgment are necessary or appropriate
to enable us to render the opinion expressed below and (ii) assumed that the
shares of the Common Stock will be sold by the Underwriters at a price
established by the Pricing Committee of the Company's Board of Directors.

On the basis of the foregoing, and in reliance thereon, we are of the opinion
that the Selling Stockholder Shares are, and the Company Shares, when sold and
issued in accordance with the Registration Statement and related Prospectus,
will be, validly issued, fully paid and nonassessable.

We consent to the reference to our firm under the caption "Legal Matters" in the

opinion as an exhibit to the Registration Statement.

Sincerely,

/s/ Suzanne Sawochka Hooper

purposes of Section 162(m) of the Code.

         V.       "PLAN" means this 1996 Equity Incentive Plan.

         W.       "RULE 16B-3" means Rule 16b-3 of the Exchange Act or any

respect to the Plan.

         X.       "SECURITIES ACT" means the Securities Act of 1933, as amended.

         Y.       "STOCK AWARD" means any right granted under the Plan,
including any Option, any stock bonus, and any right to purchase restricted

         Z.       "STOCK AWARD AGREEMENT" means a written agreement between the

the Board delegates administration to a Committee, as provided in subsection
3(c).

                                       3.
<PAGE>   4

         B.       The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

                  I.       To determine from time to time which of the persons
eligible under the Plan shall be granted Stock Awards; when and how each Stock
Award shall be granted; whether a Stock Award will be an Incentive Stock Option,
a Nonstatutory Stock Option, a stock bonus, a right to purchase restricted
stock, or a combination of the foregoing; the provisions of each Stock Award
granted (which need not be identical), including the time or times when a person
shall be permitted to receive stock pursuant to a Stock Award and the number of
shares with respect to which a Stock Award shall be granted to each such person.

                  II.      To construe and interpret the Plan and Stock Awards
granted under it, and to establish, amend and revoke rules and regulations for
its administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Stock Award Agreement,
in a manner and to the extent it shall deem necessary or expedient to make the
Plan fully effective.

                  III.     To amend the Plan or a Stock Award as provided in
Section 12.

                  IV.      Generally, to exercise such powers and to perform
such acts as the Board deems necessary or expedient to promote the best
interests of the Company which are not in conflict with the provisions of the
Plan.

         C.       The Board may delegate administration of the Plan to a
committee or committees ("Committee") of one or more members of the Board. If
administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed
by the Board (and references in this Plan to the Board shall thereafter be to
the Committee), subject, however, to such resolutions, not inconsistent with the
provisions of the Plan, as may be adopted from time to time by the Board. The
Board may abolish the Committee at any time and revest in the Board the
administration of the Plan. In the discretion of the Board, a Committee may
consist solely of two or more Outside Directors in accordance with Section
162(m) of the Code and/or two or more Non-Employee Directors, in accordance with
Rule 16b-3. The Board may (i) delegate to a committee of one or more members of
the Board who are not Outside Directors the authority to grant Stock Awards to
eligible persons who are either (1) not then Covered Employees and are not
expected to be Covered Employees at the time of recognition of income resulting
from such Stock Award or (2) not persons with respect to whom the Company wishes
to comply with Section 162(m) of the Code and/or (ii) delegate to a committee of
one or more members of the Board who are not Non-Employee Directors the
authority to grant Stock Awards to eligible persons who are not then subject to
Section 16 of the Exchange Act.

4.       SHARES SUBJECT TO THE PLAN.

         A.       Subject to the provisions of Section 11 relating to
adjustments upon changes in stock, the stock that may be issued pursuant to
Stock Awards shall not exceed in the aggregate six million (6,000,000) shares of
Common Stock, plus an annual increase to be added on each June 1, beginning with
June 1, 2000, equal to the lesser of (i) five percent (5%) of the total number
of shares of Common Stock outstanding on such anniversary date, or (ii) four
million five hundred thousand (4,500,000) shares. If any Stock Award shall for
any reason expire or otherwise terminate, in whole or in part, without having
been exercised in full (or vested in the case of restricted stock), the stock

                                       4.
<PAGE>   5

not acquired under such Stock Award shall revert to and again become available
for issuance under the Plan.

         B.       The stock subject to the Plan may be unissued shares or
reacquired shares, bought on the market or otherwise.

5.       ELIGIBILITY.

         A.       Incentive Stock Options may be granted only to Employees.
Stock Awards other than Incentive Stock Options may be granted to Employees,
Directors or Consultants.

         B.       No person shall be eligible for the grant of an Incentive
Stock Option if, at the time of grant, such person owns (or is deemed to own
pursuant to Section 424(d) of the Code) stock possessing more than ten percent
(10%) of the total combined voting power of all classes of stock of the Company
or of any of its Affiliates unless the exercise price of such Option is at least
one hundred ten percent (110%) of the Fair Market Value of such stock at the
date of grant and the Option is not exercisable after the expiration of five (5)
years from the date of grant.

         C.       SECTION 162(M) LIMITATION. Subject to the provisions of
Section 11 relating to adjustments upon changes in the shares of Common Stock,
no Employee shall be eligible to be granted Options covering more than two
million five hundred thousand (2,500,000) shares of Common Stock during any
calendar year. This subsection 5(c) shall not apply prior to the Listing Date
and, following the Listing Date, this subsection 5(c) shall not apply until (i)
the earliest of: (1) the first material modification of the Plan (including any
increase in the number of shares of Common Stock reserved for issuance under the
Plan in accordance with Section 4); (2) the issuance of all of the shares of
Common Stock reserved for issuance under the Plan; (3) the expiration of the
Plan; or (4) the first meeting of shareholders at which Directors are to be
elected that occurs after the close of the third calendar year following the
calendar year in which occurred the first registration of an equity security
under Section 12 of the Exchange Act; or (ii) such other date required by
Section 162(m) of the Code and the rules and regulations promulgated thereunder.

6.       OPTION PROVISIONS.

         Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

         A.       TERM. No Option shall be exercisable after the expiration of
ten (10) years from the date it was granted.

         B.       PRICE. The exercise price of each Incentive Stock Option shall
be not less than one hundred percent (100%) of the Fair Market Value of the
stock subject to the Option on the date the Option is granted. Notwithstanding
the foregoing, an Incentive Stock Option may be granted with an exercise price
lower than that set forth in the preceding sentence if such Option is granted
pursuant to an assumption or substitution for another option in a manner
satisfying the provisions of Section 424(a) of the Code.

                                       5.
<PAGE>   6

         C.       CONSIDERATION. The purchase price of stock acquired pursuant
to an Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board or the Committee, at the time of the grant of the
Option, (1) by delivery to the Company of other Common Stock of the Company, (2)
according to a deferred payment or other arrangement (which may include, without
limiting the generality of the foregoing, the use of other Common Stock of the
Company) with the person to whom the Option is granted or to whom the Option is
transferred pursuant to subsection 6(d), or (3) in any other form of legal
consideration that may be acceptable to the Board.

         In the case of any deferred payment arrangement, interest shall be
payable at least annually and shall be charged at the minimum rate of interest
necessary to avoid the treatment as interest, under any applicable provisions of
the Code, of any amounts other than amounts stated to be interest under the
deferred payment arrangement. In addition, where required by applicable law,
deferred payment may not be made of the par value of the Company's Common Stock.

         D.       TRANSFERABILITY. An Incentive Stock Option shall not be
transferable except by will or by the laws of descent and distribution, and
shall be exercisable during the lifetime of the person to whom the Incentive
Stock Option is granted only by such person. A Nonstatutory Stock Option may be
transferred to the extent provided in the Option Agreement; provided that if the
Option Agreement does not expressly permit the transfer of a Nonstatutory Stock
Option, the Nonstatutory Stock Option shall not be transferable except by will,
by the laws of descent and distribution or pursuant to a domestic relations
order satisfying the requirements of Rule 16b-3, and shall be exercisable during
the lifetime of the person to whom the Option is granted only by such person or
any transferee pursuant to a domestic relations order. Notwithstanding the
foregoing, the person to whom the Option is granted may, by delivering written
notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionee, shall thereafter be
entitled to exercise the Option.

         E.       VESTING. The total number of shares of stock subject to an
Option may, but need not, be allotted in periodic installments (which may, but
need not, be equal). The Option Agreement may provide that from time to time
during each of such installment periods, the Option may become exercisable
("vest") with respect to some or all of the shares allotted to that period, and
may be exercised with respect to some or all of the shares allotted to such
period and/or any prior period as to which the Option became vested but was not
fully exercised. The Option may be subject to such other terms and conditions on
the time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate, including provisions which
call for the forfeiture of the Option in the event Optionee engages in conduct
in competition with the Company's business or leading to termination for cause.
The provisions of this subsection 6(e) are subject to any Option provisions
governing the minimum number of shares as to which an Option may be exercised.

         F.       TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR
CONSULTANT. In the event an Optionee's Continuous Status as an Employee,
Director or Consultant terminates (other than upon the Optionee's death or
Disability), the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it at the date of termination) but only within
such period of time ending on the earlier of (i) the date sixty (60) days after
the termination of the Optionee's Continuous Status as an Employee, Director or
Consultant (or such longer or shorter period specified in the Option Agreement),
or (ii) the expiration of the term of the Option as set forth in the Option
Agreement. If, after termination, the Optionee does not exercise his or her
Option within the time

                                       6.
<PAGE>   7

specified in the Option Agreement, the Option shall terminate, and the shares
covered by such Option shall revert to and again become available for issuance
under the Plan.

         An Optionee's Option Agreement may also provide that if the exercise of
the Option following the termination of the Optionee's Continuous Status as an
Employee, Director or Consultant (other than upon the Optionee's death or
Disability) would be prohibited at any time solely because the issuance of
shares would violate the registration requirements under the Act, then the
Option shall terminate on the earlier of (i) the expiration of the term of the
Option set forth in the preceding paragraph, or (ii) the expiration of a period
of sixty (60) days after the termination of the Optionee's Continuous Status as
an Employee, Director or Consultant during which the exercise of the Option
would not be in violation of such registration requirements.

         G.       DISABILITY OF OPTIONEE. In the event an Optionee's Continuous
Status as an Employee, Director or Consultant terminates as a result of the
Optionee's Disability, the Optionee may exercise his or her Option (to the
extent that the Optionee was entitled to exercise it at the date of
termination), but only within such period of time ending on the earlier of (i)
the date twelve (12) months following such termination (or such longer or
shorter period specified in the Option Agreement), or (ii) the expiration of the
term of the Option as set forth in the Option Agreement. If, at the date of
termination, the Optionee is not entitled to exercise his or her entire Option,
the shares covered by the unexercisable portion of the Option shall revert to
and again become available for issuance under the Plan. If, after termination,
the Optionee does not exercise his or her Option within the time specified
herein, the Option shall terminate, and the shares covered by such Option shall
revert to and again become available for issuance under the Plan.

         H.       DEATH OF OPTIONEE. In the event of the death of an Optionee
during, or within a period specified in the Option after the termination of, the
Optionee's Continuous Status as an Employee, Director or Consultant, the Option
may be exercised (to the extent the Optionee was entitled to exercise the Option
at the date of death) by the Optionee's estate, by a person who acquired the
right to exercise the Option by bequest or inheritance or by a person designated
to exercise the option upon the Optionee's death pursuant to subsection 6(d),
but only within the period ending on the earlier of (i) the date twelve (12)
months following the date of death (or such longer or shorter period specified
in the Option Agreement), or (ii) the expiration of the term of such Option as
set forth in the Option Agreement. If, at the time of death, the Optionee was
not entitled to exercise his or her entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan. If, after death, the Option is not exercised within
the time specified herein, the Option shall terminate, and the shares covered by
such Option shall revert to and again become available for issuance under the
Plan.

         I.       EARLY EXERCISE. The Option may, but need not, include a
provision whereby the Optionee may elect at any time while an Employee, Director
or Consultant to exercise the Option as to any part or all of the shares subject
to the Option prior to the full vesting of the Option. Any unvested shares so
purchased may be subject to a repurchase right in favor of the Company or to any
other restriction the Board determines to be appropriate.

         J.       RE-LOAD OPTIONS. Without in any way limiting the authority of
the Board or Committee to make or not to make grants of Options hereunder, the
Board or Committee shall have the authority (but not an obligation) to include
as part of any Option Agreement a provision entitling the Optionee to a further
Option (a "Re-Load Option") in the event the Optionee exercises the Option
evidenced by the Option agreement, in whole or in part, by surrendering other
shares of Common


                                       7.
<PAGE>   8


Stock in accordance with this Plan and the terms and conditions of the Option
Agreement. Any such Re-Load Option (i) shall be for a number of shares equal to
the number of shares surrendered as part or all of the exercise price of such
Option; (ii) shall have an expiration date which is the same as the expiration
date of the Option the exercise of which gave rise to such Re-Load Option; and
(iii) shall have an exercise price which is equal to one hundred percent (100%)
of the Fair Market Value of the Common Stock subject to the Re-Load Option on
the date of exercise of the original Option. Notwithstanding the foregoing, a
Re-Load Option which is an Incentive Stock Option and which is granted to a 10%
stockholder (as described in subsection 5(b)), shall have an exercise price
which is equal to one hundred ten percent (110%) of the Fair Market Value of the
stock subject to the Re-Load Option on the date of exercise of the original
Option and shall have a term which is no longer than five (5) years.

         Any such Re-Load Option may be an Incentive Stock Option or a
Nonstatutory Stock Option, as the Board or Committee may designate at the time
of the grant of the original Option; provided, however, that the designation of
any Re-Load Option as an Incentive Stock Option shall be subject to the one
hundred thousand dollars ($100,000) annual limitation on exercisability of
Incentive Stock Options described in subsection 11(d) of the Plan and in Section
422(d) of the Code. There shall be no Re-Load Options on a Re-Load Option. Any
such Re-Load Option shall be subject to the availability of sufficient shares
under subsection 4(a) and shall be subject to such other terms and conditions as
the Board or Committee may determine which are not inconsistent with the express
provisions of the Plan regarding the terms of Options.

7.       TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

         Each stock bonus or restricted stock purchase agreement shall be in
such form and shall contain such terms and conditions as the Board or the
Committee shall deem appropriate. The terms and conditions of stock bonus or
restricted stock purchase agreements may change from time to time, and the terms
and conditions of separate agreements need not be identical, but each stock
bonus or restricted stock purchase agreement shall include (through
incorporation of provisions hereof by reference in the agreement or otherwise)
the substance of each of the following provisions as appropriate:

         A.       PURCHASE PRICE. The purchase price under each restricted stock
purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such agreement but in no event shall the purchase
price be less than eighty-five percent (85%) of the stock's Fair Market Value on
the date such award is made. Notwithstanding the foregoing, the Board or the
Committee may determine that eligible participants in the Plan may be awarded
stock pursuant to a stock bonus agreement in consideration for past services
actually rendered to the Company for its benefit.

         B.       TRANSFERABILITY. No rights under a stock bonus or restricted
stock purchase agreement shall be transferable except by will or the laws of
descent and distribution or, if the agreement so provides, pursuant to a
domestic relations order satisfying the requirements of Rule 16b-3, so long as
stock awarded under such agreement remains subject to the terms of the
agreement.

         C.       CONSIDERATION. The purchase price of stock acquired pursuant
to a stock purchase agreement shall be paid either: (i) in cash at the time of
purchase; (ii) at the discretion of the Board or the Committee, according to a
deferred payment or other arrangement with the person to whom the stock is sold;
or (iii) in any other form of legal consideration that may be acceptable to the
Board


                                       8.
<PAGE>   9

or the Committee in its discretion. Notwithstanding the foregoing, the Board or
the Committee to which administration of the Plan has been delegated may award
stock pursuant to a stock bonus agreement in consideration for past services
actually rendered to the Company or for its benefit.

         D.       VESTING. Shares of stock sold or awarded under the Plan may,
but need not, be subject to a repurchase option in favor of the Company in
accordance with a vesting schedule to be determined by the Board or the
Committee.

         E.       TERMINATION OF CONTINUOUS STATUS AS AN EMPLOYEE, DIRECTOR OR
CONSULTANT. In the event a Participant's Continuous Status as an Employee,
Director or Consultant terminates, the Company may repurchase or otherwise
reacquire any or all of the shares of stock held by that person which have not
vested as of the date of termination under the terms of the stock bonus or
restricted stock purchase agreement between the Company and such person.

8.       COVENANTS OF THE COMPANY.

         A.       During the terms of the Stock Awards, the Company shall keep
available at all times the number of shares of stock required to satisfy such
Stock Awards.

         B.       The Company shall seek to obtain from each regulatory
commission or agency having jurisdiction over the Plan such authority as may be
required to issue and sell shares under Stock Awards; provided, however, that
this undertaking shall not require the Company to register under the Securities
Act either the Plan, any Stock Award or any stock issued or issuable pursuant to
any such Stock Award. If, after reasonable efforts, the Company is unable to
obtain from any such regulatory commission or agency the authority which counsel
for the Company deems necessary for the lawful issuance and sale of stock under
the Plan, the Company shall be relieved from any liability for failure to issue
and sell stock upon exercise of such Stock Awards unless and until such
authority is obtained.

9.       USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to Stock Awards shall
constitute general funds of the Company.

10.      MISCELLANEOUS.

         A.       The Board shall have the power to accelerate the time at which
a Stock Award may first be exercised or the time during which a Stock Award or
any part thereof will vest, notwithstanding the provisions in the Stock Award
stating the time at which it may first be exercised or the time during which it
will vest.

         B.       Neither an Employee, Director nor a Consultant nor any person
to whom a Stock Award is transferred in accordance with the Plan shall be deemed
to be the holder of, or to have any of the rights of a holder with respect to,
any shares subject to such Stock Award unless and until such person has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.

         C.       Nothing in the Plan or any instrument executed or Stock Award
granted pursuant thereto shall confer upon any holder of Stock Awards any right
to continue in the employ of the Company or any Affiliate, or to continue
serving as a Consultant or Director, or shall affect the right


                                       9.
<PAGE>   10

of the Company or any Affiliate to terminate the employment of any Employee with
or without notice and with or without cause, or the right to terminate the
relationship of any Consultant pursuant to the terms of such Consultant's
agreement with the Company or Affiliate or service as a Director pursuant to the
Company's By-Laws.

         D.       To the extent that the aggregate Fair Market Value (determined
at the time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.

         E.       The Company may require any person to whom a Stock Award is
granted, or any person to whom a Stock Award is transferred in accordance with
the Plan, as a condition of exercising or acquiring stock under any Stock Award,
(i) to give written assurances satisfactory to the Company as to such person's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters, and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (ii) to
give written assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the Stock Award for such person's own account and
not with any present intention of selling or otherwise distributing the stock.
The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (1) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award has been registered under
a then currently effective registration statement under the Securities Act, or
(2) as to any particular requirement, a determination is made by counsel for the
Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.

         F.       To the extent provided by the terms of a Stock Award
Agreement, the person to whom a Stock Award is granted may satisfy any federal,
state or local tax withholding obligation relating to the exercise or
acquisition of stock under a Stock Award by any of the following means or by a
combination of such means: (i) tendering a cash payment; (ii) authorizing the
Company to withhold shares from the shares of the Common Stock otherwise
issuable to the participant as a result of the exercise or acquisition of stock
under the Stock Award; or (iii) delivering to the Company owned and unencumbered
shares of the Common Stock of the Company.

11.      ADJUSTMENTS UPON CHANGES IN STOCK.

         A.       If any change is made in the stock subject to the Plan, or
subject to any Stock Award, without the receipt of consideration by the Company
(through merger, consolidation, reorganization, recapitalization,
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan will be appropriately adjusted in the
class(es) and maximum number of shares subject to the Plan pursuant to
subsection 4(a), and the outstanding Stock Awards will be appropriately adjusted
in the class(es) and number of shares and price per share of stock subject to
such outstanding Stock Awards; provided, however, then in no event shall any
adjustment be made pursuant to this subsection 11(a) on account


                                       10.
<PAGE>   11

of any distribution to the Company's stockholders in cash or in kind during the
twelve month period ending July 31, 1997. Such adjustments shall be made by the
Board or the Committee, the determination of which shall be final, binding and
conclusive. (The conversion of any convertible securities of the Company shall
not be treated as a "transaction not involving the receipt of consideration by
the Company.")

         B.       In the event of: (i) a dissolution, liquidation or sale of
substantially all of the assets of the Company; (ii) a merger or consolidation
in which the Company is not the surviving corporation; or (iii) a reverse merger
in which the Company is the surviving corporation but the shares of the Common
Stock outstanding immediately preceding the merger are converted by virtue of
the merger into other property, whether in the form of securities, cash or
otherwise, then to the extent permitted by applicable law: any surviving
corporation or an Affiliate of such surviving corporation shall assume any Stock
Awards outstanding under the Plan or shall substitute similar Stock Awards for
those outstanding under the Plan. Notwithstanding the foregoing, in the event
any surviving corporation and its Affiliates do not assume such Stock Awards or
substitute similar Stock Awards for those outstanding under the Plan, then, with
respect to Stock Awards held by persons then performing services as Employees,
Directors or Consultants, the vesting of such Stock Awards shall be accelerated
in full, the holders of such Stock Awards shall be given reasonable opportunity
to exercise such Stock Awards prior to such event, and such Stock Awards shall
be terminated if not exercised prior to such event.

12.      AMENDMENT OF THE PLAN AND STOCK AWARDS.

         A.       The Board at any time, and from time to time, may amend the
Plan. However, except as provided in Section 11 relating to adjustments upon
changes in stock, no amendment shall be effective unless approved by the
stockholders of the Company where stockholder is necessary for the Plan to
satisfy the requirements of Section 422 of the Code, Rule 16b-3 or any Nasdaq or
securities exchange listing requirements.

         B.       The Board may in its sole discretion submit any other
amendment to the Plan for stockholder approval, including, but not limited to,
amendments to the Plan intended to satisfy the requirements of Section 162(m) of
the Code and the regulations thereunder regarding the exclusion of
performance-based compensation from the limit on corporate deductibility of
compensation paid to certain executive officers.

         C.       It is expressly contemplated that the Board may amend the Plan
in any respect the Board deems necessary or advisable to provide eligible
Employees, Directors or Consultants with the maximum benefits provided or to be

         Pursuant to the 1996 Equity Incentive Plan (the "Plan"), a copy of
which has been delivered to you, you have been granted an OPTION to purchase
________ common shares of Paradyne Acquisition Corp. ("Common Stock") at the
price of $______ per share, subject to the terms and conditions of the Plan and
to your agreement to the additional terms and conditions set forth herein.

The details of your option are as follows:

         1.       VESTING. Subject to the limitations contained herein and the
Plan, or as modified on any attachment hereto, your option will vest twenty-five
percent (25%) on the first anniversary date of the Vesting Start Date, rounded
down to the nearest whole number, and six and one quarter percent (6.25%) on
each three (3) month anniversary of the Vesting Start Date thereafter (for full
vesting after four (4) years), provided that vesting will cease upon the
termination of your Continuous Status as an Employee, Director or Consultant.
Notwithstanding the foregoing, your option will be forfeited as of the time you
engage in conduct leading to the termination of your employment with the Company
for Cause. For this purpose, "Cause" shall mean willful misconduct which is
materially injurious to the Company or its affiliates monetarily or otherwise.
Further, your option is subject to forfeiture to the extent not prohibited by
applicable law if you engage in competition with the Company.

         2.       WHOLE SHARES. Your option may only be exercised for whole
shares.

         3.       SECURITIES LAW COMPLIANCE. Notwithstanding anything to the
contrary contained herein, your option may not be exercised unless the shares
issuable upon exercise of your option are then registered under the Securities
Act or, if such shares are not then so registered, the Company has determined
that such exercise and issuance would be exempt from the registration
requirements of the Securities Act. All certificates representing any of the
Common Stock subject to the option shall have endorsed thereon appropriate
legends reflecting restrictions pursuant to the Plan and/or applicable
securities laws.

         4.       TERM. The term of your option commences on the Vesting Start
Date and expires upon the earliest of:

                           (i)      the tenth (10th) anniversary of the Vesting
Start Date;

                           (ii)     twelve (12) months after your death, if you
die during your Continuous Status as an Employee, Director or Consultant; or

                           (iii)    twelve (12) months after the termination of
your Continuous Status as an Employee, Director or Consultant due to disability;
or

                           (iv)     sixty (60) days after the termination of
your Continuous Status as Employee, Director or Consultant for any other reason,
provided that during any part of such sixty (60) day period the option is not
exercisable solely because of the condition set forth in Section 3 (Securities
Law Compliance), in which event the option shall not expire until the earlier of
the Expiration Date or until it shall have been exercisable for an aggregate
period of sixty (60) days after the termination of your Continuous Status as an
Employee, Director or Consultant.

         5.       EXERCISE AND METHOD OF PAYMENT.

                  (a)      You may exercise your vested option during its term
by delivering a notice of exercise (in a form designated by the Company)
together with the exercise price to the Corporate Secretary of the Company, or
to such person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require.

                  (b)      By exercising your option you agree that:

                           (i)      as a condition to any exercise of your
option, the Company may require you to enter an arrangement providing for the
payment by you to the Company of any tax withholding obligation of the Company
arising by reason of (1) the exercise of your option; (2) the lapse of any
substantial risk of forfeiture to which the shares are subject at the time of
exercise; or (3) the disposition of shares acquired upon such exercise;

                           (ii)     the Company (or a representative of the
underwriters) may, in connection with the first underwritten registration of the
offering of any securities of the Company under the Act, require that you not
sell or otherwise transfer or dispose of any shares of Common Stock or any other
securities of the Company during such period (not to exceed one hundred eighty
(180) days) following the effective date of the registration statement of the
Company filed under the Act as may be requested by the Company or the
representative of the underwriters. You further agree that the Company may
impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such period.



                                       2
<PAGE>   3


                           (c)      Payment of the exercise price by cash is due
in full upon exercise of all or any part of your option, provided that you may
elect, to the extent permitted by applicable law, to make payment pursuant to a
cashless exercise program under which, prior to the issuance of Common Stock,
results in either the receipt of cash (or check) by the Company or the receipt
of irrevocable instructions to pay the aggregate exercise price to the Company
from the sales proceeds.

         6.       TRANSFERABILITY. Your option is not transferable, except by
will or by the laws of descent and distribution, and is exercisable during your
life only by you. Notwithstanding the foregoing, by delivering written notice to
the Company, in a form satisfactory to the Company, you may designate a third
party who, in the event of your death, shall thereafter be entitled to exercise
your option.

         7.       RIGHT OF REPURCHASE. Prior to the date of the first
registration of the Common Stock under Section 12 of the Exchange Act, the
Company shall have the right, but not the obligation, to repurchase all or any
part of the shares received pursuant to the exercise of a vested option at a
price equal to the Fair Market Value of such shares at the date the Company
exercised the right to repurchase (the "Repurchase Option"). The Repurchase
Option shall expire 90 days following the termination of your Continuous Status
as an Employee, Director or Consultant (the "Repurchase Period"). The Repurchase
Option shall be exercised by the Company giving you, or your legal
representative, written notice of its intention to exercise the Repurchase
Option on or before the last day of the Repurchase Period. The Company may, in
exercising the Repurchase Option, designate one or more nominees to purchase the
shares, whether with or without the participation of the Company.

         8.       OPTION NOT AN EMPLOYMENT CONTRACT. Your option is not an
employment contract and nothing in your option shall be deemed to create in any
way whatsoever any obligation on your part to continue in the employ of the
Company, or of the Company to continue your employment with the Company.

         9.       NOTICES. Any notices provided for in your option or the Plan
shall be given in writing and shall be deemed effectively given upon receipt or,
in the case of notices delivered by the Company to you, five (5) days after
deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company.


         10.      GOVERNING PLAN DOCUMENT. Your option is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of your
option, including without limitation the provisions of the Plan relating to
option provisions, and is further subject to all interpretations, amendments,
rules and regulations which may from time to time be promulgated and adopted
pursuant to the Plan. In the event of any conflict between the provisions of
your option and those of the Plan, the provisions of the Plan shall control.
Defined terms not explicitly defined in this Agreement but defined in the Plan
shall have the same definitions as in the Plan.

with the exception of (i) options previously granted and delivered to you under
the Plan and (ii) the terms on the attachment hereto, if any, agreed to by you

                           PARADYNE ACQUISITION CORP.

                        1999 EMPLOYEE STOCK PURCHASE PLAN

            APPROVED BY THE BOARD OF DIRECTORS _______________, 1999
                 APPROVED BY STOCKHOLDERS _______________, 1999
                        TERMINATION DATE _______________

1.       PURPOSE.

         (A)      The purpose of this Employee Stock Purchase Plan (the "Plan")
is to provide a means by which employees of Paradyne Acquisition Corp. (the
"Company") and its Affiliates, as defined in subparagraph 1(b), which are
designated as provided in subparagraph 2(b), may be given an opportunity to
purchase common stock of the Company (the "Common Stock").

         (B)      The word "Affiliate" as used in the Plan means any parent
corporation or subsidiary corporation of the Company, as those terms are defined
in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986,
as amended (the "Code").

         (C)      The Company, by means of the Plan, seeks to retain the
services of its employees, to secure and retain the services of new employees,
and to provide incentives for such persons to exert maximum efforts for the
success of the Company.

         (D)      The Company intends that the rights to purchase stock of the
Company granted under the Plan be considered options issued under an "employee
stock purchase plan" as that term is defined in Section 423(b) of the Code.

2.       ADMINISTRATION.

         (A)      The Plan shall be administered by the Board of Directors (the
"Board") of the Company unless and until the Board delegates administration to a
Committee, as provided in subparagraph 2(c). Whether or not the Board has
delegated administration, the Board shall have the final power to determine all
questions of policy and expediency that may arise in the administration of the
Plan.

         (B)      The Board shall have the power, subject to, and within the
limitations of, the express provisions of the Plan:

                  (I)      To determine when and how rights to purchase stock of
the Company shall be granted and the provisions of each offering of such rights
(which need not be identical).

                  (II)     To designate from time to time which Affiliates of
the Company shall be eligible to participate in the Plan.

                  (III)    To construe and interpret the Plan and rights granted
under it, and to establish, amend and revoke rules and regulations for its
administration. The Board, in the


                                       1.
<PAGE>   2

exercise of this power, may correct any defect, omission or inconsistency in the
Plan, in a manner and to the extent it shall deem necessary or expedient to make
the Plan fully effective.

                  (IV)     To amend the Plan as provided in paragraph 13.

                  (V)      Generally, to exercise such powers and to perform
such acts as the Board deems necessary or expedient to promote the best
interests of the Company and its Affiliates and to carry out the intent that the
Plan be treated as an "employee stock purchase plan" within the meaning of
Section 423 of the Code.

         (C)      The Board may delegate administration of the Plan to a
Committee composed of not fewer than two (2) members of the Board (the
"Committee"). If administration is delegated to a Committee, the Committee shall
have, in connection with the administration of the Plan, the powers theretofore
possessed by the Board, subject, however, to such resolutions, not inconsistent
with the provisions of the Plan, as may be adopted from time to time by the
Board. The Board may abolish the Committee at any time and revest in the Board
the administration of the Plan.

3.       SHARES SUBJECT TO THE PLAN.

         (A)      Subject to the provisions of paragraph 12 relating to
adjustments upon changes in stock and subject to the increase in the number of
reserved shares described below, the stock that may be sold pursuant to rights
granted under the Plan shall not exceed in the aggregate one million (1,000,000)
shares of Common Stock (the "Reserved Shares"). As of the first nine (9)
anniversaries of the Effective Date of the Plan, the number of Reserved Shares
will be increased automatically by the lesser of (i) two percent (2%) of the
total number of shares of Common Stock outstanding on such anniversary date, or
(ii) one million (1,000,000) shares. If any right granted under the Plan shall
for any reason terminate without having been exercised, the Common Stock not
purchased under such right shall again become available for the Plan.

         (B)      The stock subject to the Plan may be unissued shares or
reacquired shares, bought on the market or otherwise.

4.       GRANT OF RIGHTS; OFFERING.

         The Board or the Committee may from time to time grant or provide for
the grant of rights to purchase Common Stock of the Company under the Plan to
eligible employees (an "Offering") on a date or dates (the "Offering Date(s)")
selected by the Board or the Committee. Each Offering shall be in such form and
shall contain such terms and conditions as the Board or the Committee shall deem
appropriate, which shall comply with the requirements of Section 423(b)(5) of
the Code that all employees granted rights to purchase stock under the Plan
shall have the same rights and privileges. The terms and conditions of an
Offering shall be incorporated by reference into the Plan and treated as part of
the Plan. The provisions of separate Offerings need not be identical, but each
Offering shall include (through incorporation of the provisions of this Plan by
reference in the document comprising the Offering or otherwise) the period
during which the Offering shall be effective, which period shall not exceed
twenty-seven


                                       2.
<PAGE>   3


(27) months beginning with the Offering Date, and the substance of the
provisions contained in paragraphs 5 through 8, inclusive.

5.       ELIGIBILITY.

         (A)      Rights may be granted only to employees of the Company or, as
the Board or the Committee may designate as provided in subparagraph 2(b), to
employees of any Affiliate of the Company. Except as provided in subparagraph
5(b), an employee of the Company or any Affiliate shall not be eligible to be
granted rights under the Plan unless, on the Offering Date, such employee has
been in the employ of the Company or any Affiliate for such continuous period
preceding such grant as the Board or the Committee may require, but in no event
shall the required period of continuous employment be greater than two (2)
years. In addition, unless otherwise determined by the Board or the Committee
and set forth in the terms of the applicable Offering, no employee of the
Company or any Affiliate shall be eligible to be granted rights under the Plan,
unless, on the Offering Date, such employee's customary employment with the
Company or such Affiliate is for at least twenty (20) hours per week and at
least five (5) months per calendar year.

         (B)      The Board or the Committee may provide that each person who,
during the course of an Offering, first becomes an eligible employee of the
Company or designated Affiliate will, on a date or dates specified in the
Offering which coincides with the day on which such person becomes an eligible
employee or occurs thereafter, receive a right under that Offering, which right
shall thereafter be deemed to be a part of that Offering. Such right shall have
the same characteristics as any rights originally granted under that Offering,
as described herein, except that:

                  (I)      the date on which such right is granted shall be the
"Offering Date" of such right for all purposes, including determination of the
exercise price of such right;

                  (II)     the period of the Offering with respect to such right
shall begin on its Offering Date and end coincident with the end of such
Offering; and

                  (III)    the Board or the Committee may provide that if such
person first becomes an eligible employee within a specified period of time
before the end of the Offering, he or she will not receive any right under that
Offering.

         (C)      No employee shall be eligible for the grant of any rights
under the Plan if, immediately after any such rights are granted, such employee
owns stock possessing five percent (5%) or more of the total combined voting
power or value of all classes of stock of the Company or of any Affiliate. For
purposes of this subparagraph 5(c), the rules of Section 424(d) of the Code
shall apply in determining the stock ownership of any employee, and stock which
such employee may purchase under all outstanding rights and options shall be
treated as stock owned by such employee.

         (D)      An eligible employee may be granted rights under the Plan only
if such rights, together with any other rights granted under "employee stock
purchase plans" of the Company


                                       3.
<PAGE>   4

and any Affiliates, as specified by Section 423(b)(8) of the Code, do not permit
such employee's rights to purchase stock of the Company or any Affiliate to
accrue at a rate which exceeds twenty-five thousand dollars ($25,000) of fair
market value of such stock (determined at the time such rights are granted) for
each calendar year in which such rights are outstanding at any time.

         (E)      Officers of the Company and any designated Affiliate shall be
eligible to participate in Offerings under the Plan; provided, however, that the
Board may provide in an Offering that certain employees who are highly
compensated employees within the meaning of Section 423(b)(4)(D) of the Code
shall not be eligible to participate.

6.       RIGHTS; PURCHASE PRICE.

         (A)      On each Offering Date, each eligible employee, pursuant to an
Offering made under the Plan, shall be granted the right to purchase up to the
number of shares of Common Stock of the Company purchasable with a percentage
designated by the Board or the Committee not exceeding fifteen percent (15%) of
such employee's Earnings (as defined in subparagraph 7(a)) during the period
which begins on the Offering Date (or such later date as the Board or the
Committee determines for a particular Offering) and ends on the date stated in
the Offering, which date shall be no later than the end of the Offering. The
Board or the Committee shall establish one or more dates during an Offering (the
"Purchase Date(s)") on which rights granted under the Plan shall be exercised
and purchases of Common Stock carried out in accordance with such Offering.

         (B)      In connection with each Offering made under the Plan, the
Board or the Committee may specify a maximum number of shares that may be
purchased by any employee as well as a maximum aggregate number of shares that
may be purchased by all eligible employees pursuant to such Offering. In
addition, in connection with each Offering that contains more than one Purchase
Date, the Board or the Committee may specify a maximum aggregate number of
shares which may be purchased by all eligible employees on any given Purchase
Date under the Offering. If the aggregate purchase of shares upon exercise of
rights granted under the Offering would exceed any such maximum aggregate
number, the Board or the Committee shall make a pro rata allocation of the
shares available in as nearly a uniform manner as shall be practicable and as it
shall deem to be equitable.

         (C)      The purchase price of stock acquired pursuant to rights
granted under the Plan shall be not less than the lesser of:

                  (I)      an amount equal to eighty-five percent (85%) of the
fair market value of the stock on the Offering Date; or

                  (II)     an amount equal to eighty-five percent (85%) of the
fair market value of the stock on the Purchase Date.

7.       PARTICIPATION; WITHDRAWAL; TERMINATION.

         (A)      An eligible employee may become a participant in the Plan
pursuant to an Offering by delivering a participation agreement to the Company
within the time specified in the Offering,


                                       4.
<PAGE>   5

in such form as the Company provides. Each such agreement shall authorize
payroll deductions of up to the maximum percentage specified by the Board or the
Committee of such employee's Earnings during the Offering. "Earnings" is defined
as an employee's wages (including amounts thereof elected to be deferred by the
employee, that would otherwise have been paid, under any arrangement established
by the Company that is intended to comply with Section 125, Section 401(k),
Section 402(h) or Section 403(b) of the Code or that provides non-qualified
deferred compensation), which shall include overtime pay, bonuses, incentive
pay, and commissions, but shall exclude profit sharing or other remuneration
paid directly to the employee, the cost of employee benefits paid for by the
Company or an Affiliate, education or tuition reimbursements, imputed income
arising under any group insurance or benefit program, traveling expenses,
business and moving expense reimbursements, income received in connection with
stock options, contributions made by the Company or an Affiliate under any
employee benefit plan, and similar items of compensation, as determined by the
Board or the Committee. The payroll deductions made for each participant shall
be credited to an account for such participant under the Plan and shall be
deposited with the general funds of the Company. A participant may reduce
(including to zero) or increase such payroll deductions, and an eligible
employee may begin such payroll deductions, after the beginning of any Offering
only as provided for in the Offering. A participant may make additional payments
into his or her account only if specifically provided for in the Offering and
only if the participant has not had the maximum amount withheld during the
Offering.

         (B)      At any time during an Offering, a participant may terminate
his or her payroll deductions under the Plan and withdraw from the Offering by
delivering to the Company a notice of withdrawal in such form as the Company
provides. Such withdrawal may be elected at any time prior to the end of the
Offering except as provided by the Board or the Committee in the Offering. Upon
such withdrawal from the Offering by a participant, the Company shall distribute
to such participant all of his or her accumulated payroll deductions (reduced to
the extent, if any, such deductions have been used to acquire stock for the
participant) under the Offering, without interest, and such participant's
interest in that Offering shall be automatically terminated. A participant's
withdrawal from an Offering will have no effect upon such participant's
eligibility to participate in any other Offerings under the Plan but such
participant will be required to deliver a new participation agreement in order
to participate in subsequent Offerings under the Plan.

         (C)      Rights granted pursuant to any Offering under the Plan shall
terminate immediately upon cessation of any participating employee's employment
with the Company and any designated Affiliate, for any reason, and the Company
shall distribute to such terminated employee all of his or her accumulated
payroll deductions (reduced to the extent, if any, such deductions have been
used to acquire stock for the terminated employee), under the Offering, without
interest.

         (D)      Rights granted under the Plan shall not be transferable by a
participant otherwise than by will or the laws of descent and distribution, or
by a beneficiary designation as provided in paragraph 14 and, otherwise during
his or her lifetime, shall be exercisable only by the person to whom such rights
are granted.

         (A)      On each Purchase Date specified therefor in the relevant
Offering, each participant's accumulated payroll deductions and other additional
payments specifically provided for in the Offering (without any increase for
interest) will be applied to the purchase of whole shares of stock of the
Company, up to the maximum number of shares permitted pursuant to the terms of
the Plan and the applicable Offering, at the purchase price specified in the
Offering. No fractional shares shall be issued upon the exercise of rights
granted under the Plan. The amount, if any, of accumulated payroll deductions
remaining in each participant's account after the purchase of shares which is
less than the amount required to purchase one share of stock on the final
Purchase Date of an Offering shall be held in each such participant's account
for the purchase of shares under the next Offering under the Plan, unless such
participant withdraws from such next Offering, as provided in subparagraph 7(b),
or is no longer eligible to be granted rights under the Plan, as provided in
paragraph 5, in which case such amount shall be distributed to the participant
after such final Purchase Date, without interest. The amount, if any, of
accumulated payroll deductions remaining in any participant's account after the
purchase of shares which is equal to the amount required to purchase whole
shares of stock on the final Purchase Date of an Offering shall be distributed
in full to the participant after such Purchase Date, without interest.

         (B)      No rights granted under the Plan may be exercised to any
extent unless the shares to be issued upon such exercise under the Plan
(including rights granted thereunder) are covered by an effective registration
statement pursuant to the Securities Act of 1933, as amended (the "Securities
Act") and the Plan is in material compliance with all applicable state, foreign
and other securities and other laws applicable to the Plan. If on a Purchase
Date in any Offering hereunder the Plan is not so registered or in such
compliance, no rights granted under the Plan or any Offering shall be exercised
on such Purchase Date, and the Purchase Date shall be delayed until the Plan is
subject to such an effective registration statement and such compliance, except
that the Purchase Date shall not be delayed more than twelve (12) months and the
Purchase Date shall in no event be more than twenty-seven (27) months from the
Offering Date. If on the Purchase Date of any Offering hereunder, as delayed to
the maximum extent permissible, the Plan is not registered and in such
compliance, no rights granted under the Plan or any Offering shall be exercised
and all payroll deductions accumulated during the Offering (reduced to the
extent, if any, such deductions have been used to acquire stock) shall be
distributed to the participants, without interest.

9.       COVENANTS OF THE COMPANY.

         (A)      During the terms of the rights granted under the Plan, the
Company shall keep available at all times the number of shares of stock required
to satisfy such rights.

         (B)      The Company shall seek to obtain from each federal, state,
foreign or other regulatory commission or agency having jurisdiction over the
Plan such authority as may be required to issue and sell shares of stock upon
exercise of the rights granted under the Plan. If, after reasonable efforts, the
Company is unable to obtain from any such regulatory commission or agency the
authority which counsel for the Company deems necessary for the lawful issuance
and


                                       6.
<PAGE>   7

sale of stock under the Plan, the Company shall be relieved from any liability
for failure to issue and sell stock upon exercise of such rights unless and
until such authority is obtained.

10.      USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to rights granted under the
Plan shall constitute general funds of the Company.

11.      RIGHTS AS A STOCKHOLDER.

         A participant shall not be deemed to be the holder of, or to have any
of the rights of a holder with respect to, any shares subject to rights granted
under the Plan unless and until the participant's shareholdings acquired upon
exercise of rights under the Plan are recorded in the books of the Company.

12.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (A)      If any change is made in the stock subject to the Plan, or
subject to any rights granted under the Plan, due to a change in corporate
capitalization and without the receipt of consideration by the Company (through
reincorporation, stock dividend, stock split, reverse stock split, combination
or reclassification of shares), the Plan will be appropriately adjusted in the
class(es) and maximum number of securities subject to the Plan pursuant to
subsection 3(a), and the outstanding rights will be appropriately adjusted in
the class(es) and number of securities and price per share of stock subject to
such outstanding rights. Such adjustments shall be made by the Board, the
determination of which shall be final, binding and conclusive.

         (B)      In the event of: (1) a dissolution, liquidation or sale of all
or substantially all of the assets of the Company, (2) a merger or consolidation
in which the Company is not the surviving corporation, or (3) a reverse merger
in which the Company is the surviving corporation but the shares of Common Stock
outstanding immediately preceding the merger are converted by virtue of the
merger into other property, whether in the form of securities, cash or
otherwise, then, as determined by the Board in its sole discretion, (i) any
surviving corporation may assume outstanding rights or substitute similar rights
for those under the Plan, (ii) such rights may continue in full force and
effect, or (iii) participants' accumulated payroll deductions may be used to
purchase Common Stock immediately prior to the transaction described above and
the participants' rights under the ongoing Offering terminated.

13.      AMENDMENT OF THE PLAN.

         (A)      The Board at any time, and from time to time, may amend the
Plan. However, except as provided in paragraph 12 relating to adjustments upon
changes in stock, no amendment shall be effective unless approved by the
stockholders of the Company within twelve (12) months before or after the
adoption of the amendment, where the amendment will:

                  (I)      Increase the number of shares reserved for rights
under the Plan;

                                       7.
<PAGE>   8

                  (II)     Modify the provisions as to eligibility for
participation in the Plan (to the extent such modification requires stockholder
approval in order for the Plan to obtain employee stock purchase plan treatment
under Section 423 of the Code or to comply with the requirements of Rule 16b-3
promulgated under the Securities Exchange Act of 1934, as amended ("Rule
16b-3")); or

                  (III)    Modify the Plan in any other way if such modification
requires stockholder approval in order for the Plan to obtain employee stock
purchase plan treatment under Section 423 of the Code or to comply with the
requirements of Rule 16b-3.

It is expressly contemplated that the Board may amend the Plan in any respect
the Board deems necessary or advisable to provide eligible employees with the
maximum benefits provided or to be provided under the provisions of the Code and
the regulations promulgated thereunder relating to employee stock purchase plans
and/or to bring the Plan and/or rights granted under it into compliance
therewith.

         (B)      Rights and obligations under any rights granted before
amendment of the Plan shall not be impaired by any amendment of the Plan, except
with the consent of the person to whom such rights were granted, or except as
necessary to comply with any laws or governmental regulations, or except as
necessary to ensure that the Plan and/or rights granted under the Plan comply
with the requirements of Section 423 of the Code.

14.      DESIGNATION OF BENEFICIARY.

         (A)      A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under the Plan in the event of such participant's death subsequent to the end of
an Offering but prior to delivery to the participant of such shares and cash. In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under the Plan in the event
of such participant's death during an Offering.

         (B)      Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its sole discretion, may
deliver such shares and/or cash to the spouse or to any one or more dependents
or relatives of the participant, or if no spouse, dependent or relative is known
to the Company, then to such other person as the Company may designate.

15.      TERMINATION OR SUSPENSION OF THE PLAN.

         (A)      The Board in its discretion, may suspend or terminate the Plan
at any time. No rights may be granted under the Plan while the Plan is suspended
or after it is terminated.

         (B)      Rights and obligations under any rights granted while the Plan
is in effect shall not be altered or impaired by suspension or termination of
the Plan, except as expressly provided in


                                       8.
<PAGE>   9


the Plan or with the consent of the person to whom such rights were granted, or
except as necessary to comply with any laws or governmental regulation, or
except as necessary to ensure that the Plan and/or rights granted under the Plan
comply with the requirements of Section 423 of the Code.

         (C)      Notwithstanding the foregoing, the Plan shall terminate and no
rights may be granted under the Plan after the tenth anniversary of the
Effective Date.

16.      EFFECTIVE DATE OF PLAN.

         The Plan shall become effective simultaneously with the effectiveness
of the Company's registration statement under the Securities Act with respect to
the initial public offering of shares of the Company's Common Stock (the
"Effective Date"), but no rights granted under the Plan shall be exercised
unless and until the Plan has been approved by the stockholders of the Company
within twelve (12) months before or after the date the Plan is adopted by the
Board, which date may be prior to the Effective Date.

1.       PURPOSES.

         (A)      ELIGIBLE OPTION RECIPIENTS. The persons eligible to receive
Options are the Non-Employee Directors of the Company.

         (B)      AVAILABLE OPTIONS. The purpose of the Plan is to provide a

from increases in value of the Common Stock through the granting of Nonstatutory
Stock Options.

         (C)      GENERAL PURPOSE. The Company, by means of the Plan, seeks to
retain the services of its Non-Employee Directors, to secure and retain the
services of new Non-Employee Directors and to provide incentives for such
persons to exert maximum efforts for the success of the Company and its
Affiliates.

corporation of the Company, whether now or hereafter existing, as those terms
are defined in Sections 424(e) and (f), respectively, of the Code.

         (B)      "ANNUAL GRANT" means an Option granted annually to all
Non-Employee Directors who meet the specified criteria pursuant to subsection

Affiliate as an Employee, Consultant or Director or a change in the entity for
which the Optionholder renders such service, provided that there is no
interruption or termination of the Optionholder's Continuous Service. For

leave or any other personal leave.

                  (I)      To determine the provisions of each Option to the
extent not specified in the Plan.

                  (II)     To construe and interpret the Plan and Options
granted under it, and to establish, amend and revoke rules and regulations for
its administration. The Board, in the exercise of this power, may correct any
defect, omission or inconsistency in the Plan or in any Option Agreement, in a
manner and to the extent it shall deem necessary or expedient to make the Plan
fully effective.

                  (III)    To amend the Plan or an Option as provided in Section

4.       SHARES SUBJECT TO THE PLAN.

         (A)      SHARE RESERVE. Subject to the provisions of Section 11
relating to adjustments upon changes in stock, the stock that may be issued
pursuant to Options shall not exceed in the aggregate two hundred and fifty
thousand (250,000) shares of Common Stock.

         (B)      REVERSION OF SHARES TO THE SHARE RESERVE. If any Option shall
for any reason expire or otherwise terminate, in whole or in part, without
having been exercised in full, the stock not acquired under such Option shall
revert to and again become available for issuance under the Plan.

         (C)      SOURCE OF SHARES. The stock subject to the Plan may be
unissued shares or reacquired shares, bought on the market or otherwise.

5.       ELIGIBILITY.

         Nondiscretionary Options as set forth in section 6 shall be granted
under the Plan to all Non-Employee Directors.

6.       NON-DISCRETIONARY GRANTS.

         (A)      INITIAL GRANTS. Without any further action of the Board, each
Non-Employee Director shall be granted the following Options:

                  (I)      On the effective date of the Plan, each person who is
         then a Non-Employee Director automatically shall be granted an Initial
         Grant to purchase ten thousand (10,000) shares of Common Stock on the
         terms and conditions set forth herein.

                  (II)     Each person who is elected or appointed for the first
         time to be a Non-Employee Director after the effective date of the Plan
         automatically shall, upon the date of his or her initial election or
         appointment to be a Non-Employee Director by the Board or stockholders
         of the Company, be granted an Initial Grant to purchase ten thousand
         (10,000) shares of Common Stock on the terms and conditions set forth
         herein.

         (B)      ANNUAL GRANTS. On the day following each Annual Meeting
commencing with the Annual Meeting in 2000, each person who is then a
Non-Employee Director and who has attended 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 automatically shall be granted an Annual Grant to
purchase five thousand (5,000) shares of Common Stock on the terms and
conditions set forth herein; provided, however, that if the person has not been
serving as a Non-Employee Director for the entire period since the preceding
Annual Meeting, then (i) the seventy-five percent (75%) attendance requirement
shall be calculated based only on the number of scheduled meetings that occur
during the period in which the person served as a Non-Employee Director, and
(ii) the number of shares subject to the Annual Grant shall be reduced


                                       4.
<PAGE>   5

pro rata for each full quarter prior to the date of grant during which such
person did not serve as a Non-Employee Director.

7.       OPTION PROVISIONS.

         Each Option shall be in such form and shall contain such terms and
conditions as required by the Plan. Each Option shall contain such additional
terms and conditions, not inconsistent with the Plan, as the Board shall deem
appropriate. Each Option shall include (through incorporation of provisions
hereof by reference in the Option or otherwise) the substance of each of the
following provisions:

         (A)      TERM. The Board shall determine, in its sole discretion, the
term of each Option; provided that no Option shall be exercisable after the
expiration of ten (10) years from the date it is granted.

         (B)      EXERCISE PRICE. The exercise price of each Option shall be one
hundred percent (100%) of the Fair Market Value of the stock subject to the
Option on the date the Option is granted. Notwithstanding the foregoing, an
Option may be granted with an exercise price lower than that set forth in the
preceding sentence if such Option is granted pursuant to an assumption or
substitution for another option in a manner satisfying the provisions of Section
424(a) of the Code.

         (C)      CONSIDERATION. The purchase price of stock acquired pursuant
to an Option may be paid, to the extent permitted by applicable statutes and
regulations, in any combination of (i) cash or check, (ii) delivery to the
Company of other Common Stock, (ii) deferred payment or (iv) any other form of
legal consideration that may be acceptable to the Board and provided in the
Option Agreement; provided, however, that at any time that the Company is
incorporated in Delaware, payment of the Common Stock's "par value," as defined
in the Delaware General Corporation Law, shall not be made by deferred payment.

         In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

         (D)      TRANSFERABILITY. An Option shall not be transferable except by
will or by the laws of descent and distribution and shall be exercisable during
the lifetime of the Optionholder only by the Optionholder. Notwithstanding the
foregoing, the Optionholder may, by delivering written notice to the Company, in
a form satisfactory to the Company, designate a third party who, in the event of
the death of the Optionholder, shall thereafter be entitled to exercise the
Option.

         (E)      VESTING GENERALLY. Options shall vest and become exercisable
as follows:

                  (I)      Initial Grants may, at the discretion of the Board,
be (i) fully vested and exercisable on the date of grant, or (ii) vested and
exercisable as to fifty percent (50%) of the shares subject to the option on the
date of grant and as to the remaining fifty percent (50%) of the shares subject
to the option on the first anniversary of the date of grant.

                                       5.
<PAGE>   6

                  (II)     Annual Grants shall be fully vested and exercisable
on the date of grant.

         (F)      TERMINATION OF CONTINUOUS SERVICE. In the event an
Optionholder's Continuous Service terminates (other than upon the Optionholder's
death or Disability), the Optionholder may exercise his or her Option (to the
extent that the Optionholder was entitled to exercise it as of the date of
termination) but only within such period of time ending on the earlier of (i)
the date three (3) months following the termination of the Optionholder's
Continuous Service, or (ii) the expiration of the term of the Option as set
forth in the Option Agreement. If, after termination, the Optionholder does not
exercise his or her Option within the time specified in the Option Agreement,
the Option shall terminate.

         (G)      EXTENSION OF TERMINATION DATE. If the exercise of the Option
following the termination of the Optionholder's Continuous Service (other than
upon the Optionholder's death or Disability) would be prohibited at any time
solely because the issuance of shares would violate the registration
requirements under the Securities Act, then the Option shall terminate on the
earlier of (i) the expiration of the term of the Option set forth in subsection
7(a) or (ii) the expiration of a period of three (3) months after the
termination of the Optionholder's Continuous Service during which the exercise
of the Option would not be in violation of such registration requirements.

         (H)      DISABILITY OF OPTIONHOLDER. In the event an Optionholder's
Continuous Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his or her Option (to the extent that the Optionholder
was entitled to exercise it as of the date of termination), but only within such
period of time ending on the earlier of (i) the date twelve (12) months
following such termination or (ii) the expiration of the term of the Option as
set forth in the Option Agreement. If, after termination, the Optionholder does
not exercise his or her Option within the time specified herein, the Option
shall terminate.

         (I)      DEATH OF OPTIONHOLDER. In the event (i) an Optionholder's
Continuous Service terminates as a result of the Optionholder's death or (ii)
the Optionholder dies within the three-month period after the termination of the
Optionholder's Continuous Service for a reason other than death, then the Option
may be exercised (to the extent the Optionholder was entitled to exercise the
Option as of the date of death) by the Optionholder's estate, by a person who
acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the Option upon the Optionholder's death, but only
within the period ending on the earlier of (1) the date eighteen (18) months
following the date of death or (2) the expiration of the term of such Option as
set forth in the Option Agreement. If, after death, the Option is not exercised
within the time specified herein, the Option shall terminate.

8.       COVENANTS OF THE COMPANY.

         (A)      AVAILABILITY OF SHARES. During the terms of the Options, the
Company shall keep available at all times the number of shares of Common Stock
required to satisfy such Options.

         (B)      SECURITIES LAW COMPLIANCE. The Company shall seek to obtain
from each regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to grant Options and to issue and sell shares of
Common Stock upon exercise of the Options; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
the Plan, any Option or any stock issued or issuable pursuant to any


                                       6.
<PAGE>   7

such Option. If, after reasonable efforts, the Company is unable to obtain from
any such regulatory commission or agency the authority which counsel for the
Company deems necessary for the lawful issuance and sale of stock under the
Plan, the Company shall be relieved from any liability for failure to issue and
sell stock upon exercise of such Options unless and until such authority is
obtained.

9.       USE OF PROCEEDS FROM STOCK.

         Proceeds from the sale of stock pursuant to Options shall constitute
general funds of the Company.

10.      MISCELLANEOUS.

         (A)      STOCKHOLDER RIGHTS. No Optionholder shall be deemed to be the
holder of, or to have any of the rights of a holder with respect to, any shares
subject to such Option unless and until such Optionholder has satisfied all
requirements for exercise of the Option pursuant to its terms.

         (B)      NO SERVICE RIGHTS. Nothing in the Plan or any instrument
executed or Option granted pursuant thereto shall confer upon any Optionholder
any right to continue to serve the Company as a Non-Employee Director or shall
affect the right of the Company or an Affiliate to terminate (i) the employment
of an Employee with or without notice and with or without cause, (ii) the
service of a Consultant pursuant to the terms of such Consultant's agreement
with the Company or an Affiliate or (iii) the service of a Director pursuant to
the Bylaws of the Company or an Affiliate, and any applicable provisions of the
corporate law of the state in which the Company or the Affiliate is
incorporated, as the case may be.

         (C)      INVESTMENT ASSURANCES. The Company may require an
Optionholder, as a condition of exercising or acquiring stock under any Option,
(i) to give written assurances satisfactory to the Company as to the
Optionholder's knowledge and experience in financial and business matters and/or
to employ a purchaser representative reasonably satisfactory to the Company who
is knowledgeable and experienced in financial and business matters and that he
or she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Option; and (ii) to give
written assurances satisfactory to the Company stating that the Optionholder is
acquiring the stock subject to the Option for the Optionholder's own account and
not with any present intention of selling or otherwise distributing the stock.
The foregoing requirements, and any assurances given pursuant to such
requirements, shall be inoperative if (iii) the issuance of the shares upon the
exercise or acquisition of stock under the Option has been registered under a
then currently effective registration statement under the Securities Act or (iv)
as to any particular requirement, a determination is made by counsel for the
Company that such requirement need not be met in the circumstances under the
then applicable securities laws. The Company may, upon advice of counsel to the
Company, place legends on stock certificates issued under the Plan as such
counsel deems necessary or appropriate in order to comply with applicable
securities laws, including, but not limited to, legends restricting the transfer
of the stock.

         (D)      WITHHOLDING OBLIGATIONS. The Optionholder may satisfy any
federal, state or local tax withholding obligation relating to the exercise or
acquisition of stock under an Option by any of the following means (in addition
to the Company's right to withhold from any


                                       7.
<PAGE>   8

compensation paid to the Optionholder by the Company) or by a combination of
such means: (i) tendering a cash payment; (ii) authorizing the Company to
withhold shares from the shares of the Common Stock otherwise issuable to the
Optionholder as a result of the exercise or acquisition of stock under the
Option; or (iii) delivering to the Company owned and unencumbered shares of the
Common Stock.

11.      ADJUSTMENTS UPON CHANGES IN STOCK.

         (A)      CAPITALIZATION ADJUSTMENTS. If any change is made in the stock
subject to the Plan, or subject to any Option, without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan will be appropriately
adjusted in the class(es) and maximum number of securities subject both to the
Plan pursuant to subsection 4(a) and to the nondiscretionary Options specified
in Section 5, and the outstanding Options will be appropriately adjusted in the
class(es) and number of securities and price per share of stock subject to such
outstanding Options. The Board shall make such adjustments, and its
determination shall be final, binding and conclusive. (The conversion of any
convertible securities of the Company shall not be treated as a transaction
"without receipt of consideration" by the Company.)

         (B)      CHANGE IN CONTROL--DISSOLUTION OR LIQUIDATION. In the event of
a dissolution or liquidation of the Company, then all outstanding Options shall
terminate immediately prior to such event.

         (C)      CHANGE IN CONTROL--ASSET SALE, MERGER, CONSOLIDATION OR
REVERSE MERGER. In the event of (i) a sale of all or substantially all of the
assets of the Company, (ii) a merger or consolidation in which the Company is
not the surviving corporation or (iii) a reverse merger in which the Company is
the surviving corporation but the shares of Common Stock outstanding immediately
preceding the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash or otherwise, then any surviving
corporation or acquiring corporation shall assume any Options outstanding under
the Plan or shall substitute similar Options (including an option to acquire the
same consideration paid to the stockholders in the transaction described in this
subsection 11(c) for those outstanding under the Plan. In the event any
surviving corporation or acquiring corporation refuses to assume such Options or
to substitute similar Options for those outstanding under the Plan, then with
respect to Options held by Optionholders whose Continuous Service has not
terminated, the vesting of such Options shall be accelerated in full, and the
Options shall terminate if not exercised at or prior to such event. With respect
to any other Options outstanding under the Plan, such Options shall terminate if
not exercised prior to such event.

12.      AMENDMENT OF THE PLAN AND OPTIONS.

         (A)      AMENDMENT OF PLAN. The Board at any time, and from time to
time, may amend the Plan. However, except as provided in Section 11 relating to
adjustments upon changes in stock, no amendment shall be effective unless
approved by the stockholders of the Company to the extent stockholder approval
is necessary to satisfy the requirements of Rule 16b-3 or any Nasdaq or
securities exchange listing requirements.

                                       8.
<PAGE>   9

         (B)      STOCKHOLDER APPROVAL. The Board may, in its sole discretion,
submit any other amendment to the Plan for stockholder approval.

         (C)      NO IMPAIRMENT OF RIGHTS. Rights under any Option granted
before amendment of the Plan shall not be impaired by any amendment of the Plan
unless (i) the Company requests the consent of the Optionholder and (ii) the
Optionholder consents in writing.

         (D)      AMENDMENT OF OPTIONS. The Board at any time, and from time to
time, may amend the terms of any one or more Options; provided, however, that
the rights under any Option shall not be impaired by any such amendment unless
(i) the Company requests the consent of the Optionholder and (ii) the
Optionholder consents in writing.

13.      TERMINATION OR SUSPENSION OF THE PLAN.

         (A)      PLAN TERM. The Board may suspend or terminate the Plan at any
time. Unless sooner terminated, the Plan shall terminate on the day before the
tenth (10th) anniversary of the date the Plan is adopted by the Board or
approved by the stockholders of the Company, whichever is earlier. No Options
may be granted under the Plan while the Plan is suspended or after it is
terminated.

         (B)      NO IMPAIRMENT OF RIGHTS. Suspension or termination of the Plan
shall not impair rights and obligations under any Option granted while the Plan
is in effect except with the written consent of the Optionholder.

14.      EFFECTIVE DATE OF PLAN.

         The Plan shall become effective as determined by the Board but no
Option shall be exercised unless and until the Plan has been approved by the
stockholders of the Company, which approval shall be within twelve (12) months
before or after the date the Plan is adopted by the Board.

15.      CHOICE OF LAW.

         All questions concerning the construction, validity and interpretation
of this Plan shall be governed by the law of the State of Florida, without
regard to such state's conflict of laws rules.

                           PARADYNE ACQUISITION CORP.

                   1999 EMPLOYEE STOCK PURCHASE PLAN OFFERING

                            ADOPTED __________, 1999



1.       GRANT; OFFERING DATE.

         (A)      The Board of Directors of Paradyne Acquisition Corp. (the
"Company"), pursuant to the Company's 1999 Employee Stock Purchase Plan (the
"Plan"), hereby authorizes the grant of rights to purchase shares of the common
stock of the Company ("Common Stock") to all Eligible Employees (an "Offering").
The first Offering shall begin simultaneously with the effectiveness of the
Company's registration statement under the Securities Act of 1933 with respect
to the initial public offering of the Company's Common Stock and end on April
30, 2001 (the "Initial Offering"). Thereafter, Offerings shall begin on each
November 1 and May 1 and each such Offering shall end on the day prior to the
second anniversary of its Offering Date. The first day of an Offering is that
Offering's "Offering Date." If an Offering Date does not fall on a day during
which the Common Stock is actively traded, then the Offering Date shall be the
next succeeding day during which the Common Stock is actively traded.

         (B)      Prior to the commencement of any Offering, the Board of
Directors (or the Committee described in subparagraph 2(c) of the Plan, if any)
may change any or all terms of such Offering and any subsequent Offerings. The
granting of rights pursuant to each Offering hereunder shall occur on each
respective Offering Date unless, prior to such date (a) the Board of Directors
(or such Committee) determines that such Offering shall not occur, or (b) no
shares remain available for issuance under the Plan in connection with the
Offering.

         (C)      Notwithstanding anything to the contrary, in the event that
the fair market value of a share of Common Stock on any Purchase Date during an
Offering is less than the fair market value of a share of Common Stock on the
Offering Date of such Offering, then following the purchase of Common Stock on
such Purchase Date: (i) the Offering shall terminate and (ii) all participants
in the just-terminated Offering shall automatically be enrolled in the new
Offering that shall commence on the day following the Purchase Date on the same
terms on which such participants were enrolled in the terminated Offering.

2.       ELIGIBLE EMPLOYEES.

         All employees of the Company and each of its Affiliates (as defined in
the Plan) incorporated in the United States shall be granted rights to purchase
Common Stock under each Offering on the Offering Date of such Offering, provided
that each such employee otherwise meets the employment requirements of
subparagraph 5(a) of the Plan (an "Eligible Employee") and that each Eligible
Employee may participate in only one Offering at any given time. Notwithstanding
the foregoing, the following employees shall NOT be Eligible Employees or be
granted rights under an Offering: (i) part-time or seasonal employees whose
customary employment is less than twenty (20) hours per week or less than five
(5) months per calendar


                                      1.
<PAGE>   11

year, and (ii) 5% stockholders (including ownership through unexercised options)
described in subparagraph 5(c) of the Plan shall not be eligible to participate.

3.       RIGHTS.

         (A)      Subject to the limitations contained herein and in the Plan,
on each Offering Date each Eligible Employee shall be granted the right to
purchase the number of shares of Common Stock purchasable with up to fifteen
percent (15%) of such Participant's Earnings (as defined in the Plan) paid
during the period of such Offering.

         (B)      The maximum number of shares that may be purchased by an
eligible employee on a Purchase Date shall not exceed five thousand (5,000)
shares. The maximum aggregate number of shares available to be purchased by all
Eligible Employees under an Offering shall be the number of shares remaining
available under the Plan on the Offering Date. If the aggregate purchase of
shares of Common Stock upon exercise of rights granted under the Offering would
exceed the maximum aggregate number of shares available, the Board shall make a
pro rata allocation of the shares available in a uniform and equitable manner.

         (C)      Notwithstanding the foregoing, no employee shall be granted an
option under the Plan which permits such employee's right to purchase stock
under this Plan and all other employee stock purchase plans (described in
Section 423 of the Code) of the Company to accrue at a rate which exceeds twenty
five thousand dollars ($25,000) of fair market value of such stock (determined
at the time such option is granted) for each calendar year in which such option
is outstanding at any time.

4.       PURCHASE PRICE.

         The purchase price of the Common Stock under the Offering shall be the
lesser of eighty-five percent (85%) of the fair market value of the Common Stock
on the Offering Date (or eighty-five percent (85%) of the fair market value of
the Common Stock on the first day on which the Company's Common Stock is
actively traded that immediately follows the Offering Date if an Offering Date
does not fall on a day during which the Company's Common Stock is actively
traded) or eighty-five percent (85%) of the fair market value of the Common
Stock on the Purchase Date (or eighty-five percent (85%) of the fair market
value of the Common Stock on the first day on which the Company's Common Stock
is actively traded that immediately precedes the Purchase Date if a Purchase
Date does not fall on a day during which the Company's Common Stock is actively
traded).

5.       PARTICIPATION.

         (A)      Except as otherwise provided herein or in the Plan, an
Eligible Employee may elect to participate in an Offering only as of the
beginning of the Offering. An Eligible Employee shall become a participant in
the Plan by delivering an agreement authorizing payroll deductions. Such
deductions shall be made each pay period and must be in whole percentages not to
exceed fifteen percent (15%) of Earnings. The agreement shall be made on such
enrollment form as the Company or a designated Affiliate provides and must be
delivered to the Company or designated Affiliate before the Offering Date to be
effective for such Offering, unless a later time for filing the enrollment form
is set by the Company for all Eligible

                                      2.
<PAGE>   12


Employees with respect to a given Offering Date. As to the Initial Offering, the
time for filing an enrollment form and commencing participation for individuals
who are Eligible Employees on the Offering Date for the Initial Offering shall
be determined by the Company and communicated to such Eligible Employees. A
participant may not make additional contributions under the Plan.

         (B)      A participant may increase or reduce (including to zero) his
or her participation level as of any May 1 or November 1 during an Offering. Any
such change in participation shall be made by delivering a notice to the Company
or a designated Affiliate in such form and at such time as the Company provides.
In addition, a participant may withdraw from an Offering and receive his or her
accumulated payroll deductions from the Offering (reduced to the extent, if any,
such deductions have been used to acquire Common Stock for the Participant on
any prior Purchase Dates), without interest, at any time prior to the end of the
Offering, excluding the fifteen (15) day period immediately preceding the
Purchase Date, by delivering a withdrawal notice to the Company or designated
Affiliate in such form as the Company of designated Affiliate provides. A
participant who has withdrawn from an Offering shall not again participate in
such Offering but may participate in subsequent Offerings under the Plan by
submitting a new participation agreement in accordance with the terms thereof.

6.       PURCHASES.

         Subject to the limitations contained herein, on each Purchase Date,
each participant's accumulated payroll deductions (without any increase for
interest) shall be applied to the purchase of whole shares of Common Stock, up
to the maximum number of shares permitted under the Plan and the Offering.
"Purchase Date" shall be defined as October 31, 1999, and each April 30 and
October 31 thereafter. If a Purchase Date does not fall on a day during which
the Common Stock is actively traded then the Purchase Date shall be the nearest
prior day on which the Common Stock is actively traded.

7.       NOTICES.

         Any notices or agreements provided for in the Offering or the Plan
shall be given in writing, in a form provided by the Company, and unless
specifically provided for in the Plan or this Offering shall be deemed
effectively given upon receipt or, in the case of notices and agreements
delivered by the Company, five (5) days after deposit in the United States mail,
postage prepaid.

8.       EXERCISE CONTINGENT ON STOCKHOLDER APPROVAL.

         The rights granted under an Offering are subject to the approval of the
Plan by the stockholders of the Company as required for the Plan to obtain
employee stock purchase plan treatment under Section 423 of the Code or to
comply with the requirements of Rule 16b-3 promulgated under the Securities
Exchange Act of 1934, as amended.

9.       OFFERING SUBJECT TO PLAN.

         Each Offering is subject to all the provisions of the Plan, and its
provisions are hereby made a part of the Offering, and is further subject to all
interpretations, amendments, rules and


                                       3.
<PAGE>   13

regulations which may from time to time be promulgated and adopted pursuant to
the Plan. In the event of any conflict between the provisions of an Offering and
those of the Plan (including interpretations, amendments, rules and regulations
which may from time to time be promulgated and adopted pursuant to the Plan),
the provisions of the Plan shall control.

                                SUPPLY AGREEMENT



                  THIS SUPPLY AGREEMENT (this "Agreement") is entered into as of
July 31, 1996 by and among LUCENT TECHNOLOGIES INC., a Delaware corporation,
having a principal office at 211 Mt. Airy Road, Basking Ridge, New Jersey 07920
and its affiliates ("Company"), AT&T Paradyne Corporation, a Delaware

Florida 33773 and CAP Acquisition Corp., a Delaware corporation, having a
principal office at 8545 126th Avenue North, Largo, Florida 33773 ("CAPCO"),
collectively referred to herein as "Supplier".

1.       TERM

                  This Agreement shall become effective as of the date here of
and shall continue in effect for a period of four (4) years. 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. In addition,
orders from affiliates (excluding AT&T Corp. and NCR Corp. when purchasing as
affiliates but not when purchasing as subcontractors) and subcontractors shall
be considered Orders for purposes of the Volume/Price Letter as outlined in a
letter agreement between Texas Pacific Group and Company dated the date of this
Agreement ("Volume/Price Letter").

3.       MATERIAL

                  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 [***] 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
[***]. If Supplier at any time [***], Supplier shall [***]. 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.

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

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
change to Supplier's Acknowledged Delivery Schedule. Supplier's compliance with
the foregoing

inquiry concerning the use of ODCs to manufacture and/or repair Material or
components thereof and to execute without additional charge any documents
reasonably required to certify the absence or quantity of ODCs used to
manufacture and/or repair Material or components thereof.

32.      COMPLIANCE WITH ENVIRONMENTAL/HEALTH AND SAFETY/TRANSPORTATION LAWS

                  Supplier agrees to comply with applicable country or state
environmental, health and safety, and transportation laws and regulations

                  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

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 indemnity shall not apply
to the extent that such claims or infringements 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

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 noninfringing product
substantially complying with such Material's Specifications and satisfactory to
Company; or (iii) modify such Material so it becomes noninfringing 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. All
payments refunded

                                       12

third party in order to fulfill the contract, then Company shall [***] set forth
in the Volume/Price Letter for the applicable period.

                  These provisions concerning late delivery of conforming

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

Agreement, whichever comes later. In addition, Supplier shall permit a third
party audit of its sales records to determine compliance with the Volume/Price
Letter.

                                       21
<PAGE>   22
                  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

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

                  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

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.

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

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

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); less [***] set forth in

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.

                                  DEMAND - PULL

                  The terms set forth herein (the "Demand Pull Arrangement")
will govern any Material on Demand Pull at a Company location, each as mutually
agreed upon by Company and Supplier.

                  1. TERM OF DEMAND PULL ARRANGEMENT - The term of the Demand
Pull Arrangement shall be specified in the Demand Pull purchase (DPP) order
acknowledged by Supplier.

                  2. DEMAND PULL PROCESS - For Demand Pull Material, Company
shall prepare and deliver to Supplier an annual DPP order(s). On Monday of each
week, Company shall provide Supplier with an updated twelve (12) month forecast,
including the Company's reasonable and good faith estimated requirements for a
minimum of the next twenty six (26) weeks, for each Demand Pull Material (the
"Forecast"). The Forecast may also contain authorization by Company to Supplier
to ship within twenty-four hours and Supplier will deliver within the week of
Supplier's receipt of the Forecast provided said Forecast is actually received
on Monday, 100% of the quantity designated in the column entitled "Ship Action"
to be received by Thursday of the current week. Supplier shall reference the
annual DPP order number on its shipping and invoicing documents. The Forecast
shall be for planning purposes only and except to the extent set forth below,
shall not be deemed a commitment by the Company to purchase from Supplier the
amount set forth in the annual DPP order or the Forecast. Company will
acknowledge receipt of Material delivered in the prior week via the succeeding
week's Forecast.

                  Supplier shall maintain (a) an inventory of inspected finished
Demand Pull Material equal to the amount of such Material forecasted to be used
by the Company during weeks one (1) through three (3) of the then current
Forecast and (b) work in process and/or raw materials and components in the
aggregate sufficient to manufacture such Demand Pull Material equivalent to
weeks four (4) through eight (8) of then current Forecast. From time to time,
the parties will review the foregoing levels of inventory, work in process
and/or raw material and components and will negotiate on lower inventory levels,
work in process and materials and components based on Supplier's satisfactory
demand pull service performance.

                  Supplier shall review the weekly Forecast and make adjustments
to Supplier's inspected inventory of Demand Pull Material, work in process and
raw materials and components based upon increases/decreases in the Forecast.
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.

                  The Company's commitment for the purchase of Demand Pull
Material shall be limited to (a) the quantities set forth in the "Ship Action"
column of the Forecast and (b) the finished and inspected by Supplier inventory
of Demand Pull Materials, work in process, raw materials and components as set
forth above.

                                      D-1
<PAGE>   37
                  The Company's liability for the items above shall be limited
to the sum of (a) the [***]; (b) [***]; and (c) [***]; less (d) [***] set forth
in (a), (b), and (c) of this paragraph. If requested by the Company, Supplier
will substantiate such costs and purchase prices with proof reasonably
satisfactory to the Company.

                  3. TERMINATION OF DEMAND PULL ARRANGEMENTS - Company may at
any time terminate any or all annual DPP orders, in whole or in part, upon
thirty (30) days written notification to Supplier. Upon receipt of such notice,
Supplier shall immediately stop work as specified in the notice to Supplier.
Company liability to Suppliers with respect to such termination shall be as set
forth in paragraph 2 above. Upon such termination, the parties shall meet
promptly to determine the finished Demand Pull Material, work in process and raw
material and components for which Company is responsible as set forth above.
Supplier shall, at Company's option and expense, ship to Company or scrap such
finished Material, work in process and raw materials and components for which
Company is liable under this Agreement.

                  4. DEMAND PULL SERVICE PERFORMANCE - The Company intends to
monitor the delivery performance of Supplier via special performance report set
forth in the clause SERVICE. Supplier will strive to achieve or exceed the
service goals established in the clause SERVICE of the Supply Agreement.

         Acquisition Corp., and Lucent, shall be deleted in its entirety and
         replaced with the following:

8.       MARKET RIGHTS.
         (a) Supplier will supply 100% of Company's requirements for Access
         Products (as defined in Subsection 8(d)) for resale as "Stand-Alone
         Products" through June 30, 2001. 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

                                       2.
<PAGE>   3
         are substantially similar in design, functionality, and operating
         characteristics to and compete in the marketplace with those Access
         Products defined in Subsection 8(d), 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
         requirement, 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) Appropriate concepts contained in the Supply Agreement, modified to
         be consistent with this Agreement, will continue including best price
         (as amended for the agreed upon process for international sales and
         excluding special bid situations, governmental sales, other unique
         sales opportunities and an added, provision for comparability of
         quantities), forecasting, ordering and delivery terms and a
         benchmarking provision.

         (d)-(i) 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
         enhancement, and their normal evolution within currently defined market
         segments:

                            COMPANY AND SUPPLIER.

             (iii)Exception Statements-
                  1. APPLICABLE ONLY TO THE SUPPLIER'S ANALOG PRODUCTS OF
                  SECTION 8(d)(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 a 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 expend 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 TI CSU AND TI DSU/CSUs OF
                  SECTION 8(d)(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 expend
                  marketing dollars, include as pan of an offer, promote, pay
                  commission or incentives nor PEC/Com code products for general
                  availability, of the other vendor's DSU/CSU products. Company
                  should first attempt to respond with Supplier's equipment and
                  revere to another vendor as a last resort.

                  3. In all of the above cases, 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 rigs 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.

         (e) Requests for Access Product enhancements and new features or new
         products shall be processed 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.

8.       SUPPLY AGREEMENT: BENCHMARKING. The parties agree that SECTION 9
         ("BENCHMARKING") of the Supply Agreement shall be deleted in its
         entirety and replaced with the following:

                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 "P Quote" process. 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

                                       5.
<PAGE>   6
                upon the framework to conduct the benchmarking process (see
                Exhibit B). This shall include clear identification of industry,
                leaders to be benchmarker.

                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 Paradyne 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 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 Amendment. If Supplier does not match or beat
                Company's offer, Company may elect to purchase Material from
                another source without further obligation of exclusivity 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 with respect 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.

This Amendment is the complete and exclusive statement of the parties with
respect to this subject matter, and merges and supersedes all communications,
negotiations and agreements between the parties with respect thereto. This
Amendment may be executed in counterparts, each of which shall be deemed an
original, and ail of which together shall constitute one and the same
instrument. Except as expressly modified herein, all agreements between, the
parties shall remain fully in effect and shall continue to bind the parties.
Without limiting the generality of the foregoing, the parties understand and
agree that the Noncompetition Agreement of July 31, 1996, by and among Lucent,
Paradyne Partners L.P., Paradyne Acquisition Corp., AT&T Paradyne Corporation,
and CAP Acquisition Corp., shall remain fully in effect and shall continue to
bind the parties.

RE:      PAYOUT ARRANGEMENTS AND FORGIVENESS OF DEBT

Ladies and Gentlemen:

         We refer to the Core Business Note dated as of July 3l, 1996 (as
amended and in effect from time to time, the "Note") issued by Paradyne
Corporation f/k/a AT&T Paradyne Corporation ("Paradyne") (the "Borrower") in
favor of Lucent Technologies Inc. (the "Lender") in the original principal
amount of $76,250,000.00.

         The Borrower has advised the Lender that it intends to repay certain
amounts due and owing under the Note (the "Loans") and has requested that the
Lender provide the Borrower with appropriate pay-off figures of the principal,
interest and other amounts owing by the Borrower to the Lender under the Note.
The pay-off figures for the Borrower as of August 6, 1998 (the "Computation
Date") under the Note are as follows (collectively, together with any additional
interest accruing, or fees and expenses incurred, after the Computation Date,
that must be paid by the Borrower, the "Pay-Off Amount"):

<TABLE>
<CAPTION>
<S>                                                 <C>
                  Principal:                        $2,711,654.29
                  Interest:                         $  109,358.09
                  Total Amount Owing                $2,821,012.37
</TABLE>

         From and after the Computation Date and until the Pay-Off Date (as
defined, below), interest shall continue to accrue on the unpaid principal
amount of the Loans at the rates set forth in the Notes. The per diem accrual of
interest on the Loans would be $854.36. Upon request of the Borrower, the Lender
shall provide the Borrower with a revised figure for the amount of interest to
be paid as part of the Pay-Off Amount plus any additional fees and expenses
incurred since the Computation Date that must be paid as part of the Pay-Off
Amount.

         Lender hereby waives the five day notice requirement set forth in
Section 2(b) of the Note.


                                       8.

         Effective immediately upon receipt of the Pay-Off amount Lender hereby
releases its lien and security interest in Borrower's assets and relinquishes
any and all right, title and interest Lender may have in such assets. Promptly
after the date hereof, but in no event later than three (3) business days,
Lender agrees to execute any UCC financing statements, including releases,
termination statements, or other documentation as Borrower may request. Lender
also agrees to promptly return the shares of capital stock of Borrower and the
stock powers issued in connection therewith to Paradyne Acquisition Corp., a
Delaware Corporation ("PAC"), pursuant to that certain Pledge Agreement dated as
of July 31, 1996 by and between Lender, PAC and Paradyne. Lender further agrees
to promptly return the cancelled Guaranty; (Core Note and Lucent Interim Note)
made by Paradyne Canada Ltd., a Canadian corporation ("Paradyne Canada"), in
favor of Lender on July 3l, 1996 to Paradyne Canada.

                                               Very truly yours,

                                               LUCENT TECHNOLOGIES INC.

7.8      Force Majeure. In the event that performance by a party under this
         Agreement is precluded or adversely materially affected because of the
         occurrence of an event,
<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,

         of public enemy, prohibition of import or export of goods covered

         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.

7.10     Credits to Tech Data. In the event any provisions of this Agreement or
         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
         this Agreement shall be deemed amended by modifying such provision, to
         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
         not be construed to be a waiver of any succeeding breach thereof or of
         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

7.14     Survival of Terms. Termination or expiration of this Agreement for any
         reason shall not release either party from any liabilities or
         obligations set forth in this Agreement which (i) the parties have
         expressly agreed shall survive any such termination or expiration, or
         (ii) remain to be performed or by their nature would be intended to be
         applicable following any such termination or expiration.

         agreed that this Agreement does not grant to AT&T PARADYNE or Tech Data

         either party from developing or acquiring other Vendors or Customers or
         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.
         This demonstration software shall be updated as appropriate to insure
         that current software is available for sales demonstration. Tech Data
         acknowledges that no title or ownership of the proprietary rights to

         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:

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

standards, IPC 610, as a minimum criteria of workmanship.

06.6.         ISO 9000 COMPLIANCE

              Seller shall, with every reasonable effort, apply for ISO 9001
registration by October 30, 1993 and be registered by March 30, 1994.

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,
to obtain the applicable approvals and certifications of FCC, UL, CSA, BSI,
BABT, DOC and VDE, and other safety and emission standards as listed in the
Purchase Specifications # 351-0047-0031, for equipment supplied by Seller.

              Sellers shall obtain such approvals and certifications prior to
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

              Buyer shall be responsible for obtaining all required approvals

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.

10.3.         PRODUCT CHANGES BY SELLER

              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.

10.5.         PRODUCT COLOR AND LOGO

              Seller will paint, logo and label the Product to the
specifications provided by the Buyer, which include the Buyer's Paint/Finish and
Color, Corporate Logo Guidelines, and Corporate Product Marking Specifications.
Seller agrees to complete this task, with every reasonable effort, 90 days after
a written request has been received from the Buyer. All non-recurring expenses
will be the responsibility of the Seller. If this Agreement is terminated prior
to the Buyer purchasing one thousand (1000) Products than the Buyer will

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

                  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

                  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.

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

and liability, including expenses and reasonable attorneys' fees, suffered by
Seller resulting from personal injury and/or tangible property damage to third
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.

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

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

Seller and Buyer, other than that of independent contractor.

              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.

<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.

19.1.         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

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.

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

Specification.

                                                      AMENDMENT NUMBER 4

PREMISYS COMMUNICATIONS, INC.
48664 MILMONT DR.
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.

         AT&T PDN within 60 days of execution of this amendment will cease its
         current development of the Eclipse Product as defined by the Eclipse
         Architecture Specification Draft Issue 1.0, dated October 21, 1994, and
         the Eclipse Release One System Requirements Specification Draft Issue
         1, dated February 13, 1995. This decision will be represented by an
         internal announcement, which will be provided under confidentiality to
         Premisys. This does not preclude any future developments from using the
         technology and know-how gained from the Eclipse Product development
         effort.

         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.

7.0      GENERAL

7.1      The term of this amendment and OEM Agreement LGSC103DS will, be five
         years from the execution of this amendment with an option to extend the
         agreement an additional two years at AT&T Paradyne's sole discretion.

contained herein shall govern the loan of the Ascend Products, including
software, listed on the attached Equipment Schedule ("Equipment") by Ascend to
Partner.

1.   Ascend agrees to deliver to Partner the Equipment (the "Equipment") for the
     period (the "Loan Period") commencing upon Ascend's delivery of Equipment
     to a common carrier for delivery to Partner F.O.B. and terminating upon
     Partner's completion of work to be provided by Partner under the Network

     parties. Partner shall utilize the Equipment in accordance with the terms
     and conditions of this Equipment Loan Agreement solely for purposes of
     performing the Services under the Network Management Partners Program
     Agreement. Nothing herein shall be construed as granting Partner a license
     under any patent, patent application, trade secret, trademark, or copyright
     which Ascend may have or obtain relating to the Equipment or Ascend's other
     products, whether announced or proposed.

2.   Title to and ownership of the Equipment are and shall at all times remain

     original condition by Partner at its expense prior to return to Ascend. If
     the Equipment is not returned within ten (10) days after notification that
     the Loan Period has expired or has been terminated, Ascend shall invoice
     Partner and a sale and license thereof shall be conclusively considered to
     have occurred at Ascend's then-current price list, subject to Ascend's
     standard terms and conditions of sale and license which shall apply to the
     sale of Equipment and this Agreement shall be deemed terminated.

6.   The Equipment is made available to Partner at Partner's request, on an
     "as-is" basis, with no warranties, representations or obligations or
     undertakings on Ascend's behalf whatsoever with respect thereto. Without
     limitation, Ascend accepts no responsibility to maintain the Equipment, nor
     with respect to any product deficiencies or defects. ASCEND MAKES NO
     EXPRESS OR IMPLIED REPRESENTATIONS OR WARRANTIES OF ANY KIND, INCLUDING BUT

     PARTICULAR PURPOSE. Ascend shall not be liable for any direct, indirect,
     incidental, special or consequential damages arising out of or in
     connection with the delivery, possession, use or operation of the
     Equipment.

7.   In the event Partner neglects or fails to perform any of its obligations
     under this Agreement and such default is not corrected to Ascend's
     satisfaction within five (5) days of receipt of Ascend's notice of such
     default, then this Agreement may be immediately terminated by Ascend. If
     the Equipment becomes, or in Ascend's opinion likely to become, the subject
     of a U.S. intellectual property infringement claim, this Agreement shall
     immediately terminate and Ascend, at its own cost and expense will remove
     the Equipment and neither party shall have any further liability to the
     other under this Agreement or otherwise. In any event, and without
     limitation, Partner shall reimburse Ascend for all costs and expenses
     (including attorney's fees) incurred by Ascend in repossessing the
     Equipment.

8.   This Agreement is not assignable. Any such assignment shall automatically
     be null and void. This Agreement supersedes all prior Agreements concerning
     the subject matter herein and may not be changed or modified except by a
     written communication signed by both parties. This Agreement constitutes
     the entire agreement governing the Equipment specified herein between
     Ascend and Partner and may not be modified or amended other than by a
     written instrument executed by both parties. This Agreement shall be
     governed by the laws of the state of Delaware.

thereafter. Such percentages shall be calculated on the immediately preceding
forecast for the same month. If orders exceed the limitations set forth in the
preceding sentence, the manufacturing party will have no obligation with respect
thereto, but the parties will discuss in good faith the additional amount, if
any, that the manufacturing party is willing to attempt to supply consistent
with its other obligations and the ordering party will adjust its order
accordingly.

If the parties determine that certain component parts required in the
manufacture of the MVP Endpoints and/or the Switch Product require more than

interchangeability with previously shipped product or compatibility at a higher
level of assembly. Upon request from the other party, that party will supply a
small number of sample products for test. If the party notifies the other that
the changes are unacceptable within ten (10) days of notification, or if samples
are involved, within fifteen (15) days of receiving the samples, the parties
will meet and in good faith develop mutually acceptable alternative solutions to
the requirement that gave rise to the need for the revision. If the other party
does not provide written notification of objection to the requesting party
within the time period specified above, the requesting party shall have no
obligation to accommodate the other party's objections.

Description of Paradyne Multiple Virtual Phone (MVP) Technology:

MVP is a subscriber line technology includes layer 1 Physical Media Dependent
and Transmission Convergence (TC) layers (TC-cell, TC-frame and TC-bit-sync)
that includes multi-drop concepts for derived POTS services and data services.
Generally, MVP includes invention from the premises POTS interface to the
central office PSTN interface. MVP provides additional POTS services to the
premises. MVP is exclusive of any data communication, including non-POTS
bit-sync data. Multiple Virtual Line (MVL) technology supports data multi-drop
concepts and is a subset and a separately licensed component of the MVP
Technology and which is not licensed under this Agreement.

Description of the Switch Product:

SuperLine(TM) Products are products that provide high speed data access and
multiple lines of telephony service -- allocating bandwidth only on demand; all
over, single cable pair with splitterless POTS support.

One of the product offerings is a SuperLine(TM) platform -- comprising a high
density central site modem that is hardened for use in remote terminal
environments as well as central offices -- combines high speed data services
with additional telephone lines, all without a truck roll to the customer
premises. In addition to the survivable (POTS) telephone service, one or two
additional telephone lines can be provided using SuperLine(TM) bandwidth, when
required. The additional telephony services support all custom features such
as: 911, Caller ID, distinctive ringing, etc., and support FAX and modem calls
up to the V90 standard. Standard analog telephone sets and the existing
telephony infrastructure of local digital switches, CO wiring billing and OAM&P
are used with these SuperLine(TM) lines. Interface to the local digital switch
is TR303, DDI and in the future TR008. Many data services are supported
including: Internet access; work at home access (corporate, governmental and
educational LANs); video meetings, IP telephony, etc.

This SuperLine(TM) platform has capacity for 96 customer links, with each line
card providing 8 ports. Each link to the customer supports 2 derived lines, as
well as, the existing POTS service and data. The shelf telephony interface
supports both DDI for the GTD5 and TR303 for GTD5, 5ESS, DMS100 and most other
digital switching product deployed throughout the network today including
Digital Loop Carrier equipment. The platform's WAN data interface is two 10/100
base T links.

The other product offerings are integrated SuperLine(TM) circuit packs designed
specifically for a particular digital switch or digital loop carrier (i.e.
Server Cards). These Server Cards bring the same technology and capability
inherent in the SuperLine(TM) platform to a single card, which can be inserted,
into an existing digital switch or digital loop carrier's line shelf. This
allows the network provider to use existing switch, power and trucking capacity
to generate additional subscriber revenue with minimum additional investment.

     The parties agree that the pricing set forth in this Appendix D shall
apply to purchases of products under this Agreement up to and including
December, 31, 1999. Thereafter, either party may change the prices listed
hereunder once per year during the term of this Agreement upon sixty-(60) days
written notice to the other party. Notwithstanding, such notice, any mutually
approved outstanding quotes or orders will be honored.

1.  MVP Premise Equipment Pricing for 1998 and 1999


     A.  The first [***] MVP Endpoints purchased by AGCS from Paradyne will be
priced at the [***] unit discount level. AGCS will then market the Derived
Telephony Product to prospective customers. Should AGCS sell the Derived
Telephony Product for more than the combined [***] unit discounted price
(AGCS' port price plus Paradyne's endpoint price), then AGCS shall pay to
Paradyne [***] percent [***] of the incremental revenue. If additional units
are required in 1998, both paries will mutually agree on the discount level.

     B.  After the sale of the initial [***] MVP Endpoints, the following
pricing shall apply to all purchases by AGCS hereunder:

EARNED DISCOUNT

The parties mutually agree that:

               a)  The earned discount period (ED Period) is defined as
January 1 to December 31 of any calendar year.

               b)  The initial discount level for 1999 will be at the 50,000
unit level. All MVP Endpoints shipped in 1998 will be added to the accumulated
volume shipped in 1999 ED period and will be eligible for earned discount for
the 1999 ED period.

               c)  The discount level achieved in a ED period will be the
initial discount level for the next ED period (e.g. if Paradyne shipped AGCS
75,000 units during the 1999 ED period, then the initial discount level for the
2000 ED period would be at the 75,000 unit level).

               d)  The discount level for an order will be based upon the
greater of the earned discount or the total number of all MVP Endpoints (A-F)
shipped prior to the specific order during that year (e.g., if Paradyne has
shipped AGCS 35,000 unit A's, 42,000 unit B's and 45,000 unit E's, the volume
discount level would be at the 1000,000 unit level because the total equals
100,000 units).

               e)  Earned discount will be determined annually. The calculation
of earned discount will be completed during January and is based on the MVP
Endpoints shipped in the previous ED period. The earned discount is the
difference between the actual discount applied to the individual orders and the
discount earned based on the accumulative total units shipped during the ED
period. Paradyne will determine if further discounts are due based upon the
discount schedule set forth above and the rules stated below. If a credit is
due, Paradyne will issue a credit to AGCS for the total amount due. Paradyne
will apply this credit to subsequent orders by AGCS hereunder. If the credit is
not fully consumed within the first calendar quarter of the current year then
Paradyne will remit to AGCS the excess amount by March 31st of the current year.
If monies are due, Paradyne will issue an invoice to AGCS for the outstanding
amount having net thirty day terms.


               Rule 1 -- Application of discount on orders during the ED period:

                         Higher level discounts will be applied to all shipments
                         when the number of units shipped exceeds the next
                         higher discount level. (e.g. during the 1999 the
                         initial discount level is at the 50,000 unit level. All
                         orders for MVP Endpoints will be priced at the 50,000
                         unit level until 75,000 units have been shipped to
                         AGCS. The 75,000 unit level discount will be applied to
                         all orders after 75,000 units have been shipped to
                         AGCS).

               Rule 2 -- Special pricing on large orders:

                         Due to market conditions, an order may receive special
                         pricing. The units shipped as part of these orders will
                         not be eligible for earned discount monies, however the
                         shipped unit volume will be used in calculating the


                                      D-2
<PAGE>   24

              total units shipped during the ED period and to determine
              the initial discount for the next ED period.

       Rule 3 -- Annual True Up of earned discount:

              Rule 3a -- Determination of the discount level achieved

                         At the end of the ED period Paradyne will review all
                         orders and calculate the actual number of units shipped
                         to determine the discount level to be applied to all
                         units shipped during the ED period. The discount level
                         achieved will be rounded to the unit level nearest to
                         the number of units shipped. (e.g. if Paradyne shipped
                         65,000 units to AGCS during 1999 then the level
                         achieved would be 75,000, if only 60,000 units were
                         shipped then the discount level achieved would be the
                         50,000 unit level discount).

              Rule 3b -- Calculation of the earned discount

                         The earned discount will be the different between the
                         initial discount applied to the units shipped and the
                         actual discount level achieved using Rule 3a. The
                         earned discount amount is determined on a per endpoint
                         type basis for each order. The total earned discount
                         for the order is the sum of earned discount amounts for
                         each endpoint type shipped with the order. If a credit
                         or invoice is required they be issued via the terms and
                         conditions defined in Section 1 B (e) of this Appendix.

              Rule 3c -- Earned discount on units shipped in different ED
                         periods

                         The units in an order are given a discount level at the
                         time the order is placed based on the actual number of
                         units shipped. The discount level determined at the
                         date of order will be used for all units shipped as
                         part of that order. This applies even when the shipment
                         schedule spans ED periods. Only the units actually
                         shipped in a given ED period will be used to determine
                         the earned discount level.

Example 1: If AGCS places four (4) orders throughout the year, and each order
placed contains various MVP Endpoint types totaling 25,000 units, the pricing
and invoicing would be as shown below: All orders were shipped within the ED
period. The discount level for all orders in the next ED period would be at
100,000 unit level.

Example 2: The earned discount level achieved in the previous period was at the
100,000 unit level. An order for 50,000 units is placed in March 99 with a
delivery schedule over the next 12 months. However, the shipment schedule
resulted in delivery of only 25,000 units during the ED period. Two other
orders totaling 40,000 units were placed and shipped during the ED period.
Therefore, earned discount must be recaptured for the ED period based on Rule
3b. The discount level for the next ED period is at the 75,000 unit level using
Rule 3c.

Earned Discount

The parties mutually agree that:

     a)  The earned discount period (ED Period) is defined as January 1 to
         December 31 of any calendar year

     b)  All Switch Products shipped to Paradyne in 1998 will be added to the
         accumulated volume shipped to Paradyne in 1999 ED period and will be
         eligible for earned discount for the 1999 ED period.

     c)  The discount level achieved in a ED period will be the initial
         discount level for the next ED period (e.g. if AGCS shipped Paradyne
         75,000 ports during the 1999 ED period, then the initial discount
         level for the 2000 ED period would be at the 75,000 port level).

     d)  The discount level for an order will be based upon the greater of the
         earned discount or the total number of all Switch Products (A-D)
         shipped prior to the specific order during the year (e.g., if AGCS has
         shipped Paradyne 35,000 unit A type ports, 42,000 units B type ports
         and 45,000 unit E type ports, the

<PAGE>   28
         volume discount level would be at the 100,000 port level because the
         total equals 100,000 ports).

     e)  Earned discount will be determined annually. The calculation of earned
         discount will be completed during January and is based on the Switch
         Product shipped in the previous "ED period". The earned discount is
         the difference between the actual discount applied to the individual
         orders and the discount earned based on the accumulative total of
         units shipped during the ED period. AGCS will determine if further
         discounts are due based upon the discount schedule set forth above and
         the rules stated below. If a credit is due AGCS will issue a credit
         for the total amount due. If the credit is not fully consumed within
         the first calendar quarter of the current year then AGCS will remit to
         Paradyne the excess amount by March 31st of the current year. If
         monies are due AGCS will issue an invoice to Paradyne for the
         outstanding amount having net thirty day terms.

     Rule 1 -- Application of discount on orders during the ED period:

         Higher level discounts will be applied to all shipments when the
         number of port shipped exceeds the next higher discount level, (e.g.
         during the 1999 the initial discount level is at the 50,000 port level.
         All orders for Switch Product will be priced at the 50,000 port level
         until 75,000 units have been shipped to Paradyne. The 75,000 port
         level discount will be applied to all orders after 75,000 ports have
         been shipped to Paradyne).

     Rule 2 -- Special pricing on large orders:

         Due to market conditions, an order may receive special pricing. The
         port shipped as part of these orders will not be eligible for earned
         discount monies, however the shipped port volume will be used in
         calculating the total ports shipped during the ED period and to
         determine the initial discount for the next ED period.

     Rule 3 -- Annual True Up of earned discount:

         Rule 3a -- Determination of the discount level achieved

             At the end of the ED period AGCS will review all orders and
             calculate the actual number of ports shipped to determine the
             discount level to be applied to all ports shipped during the ED
             period. The discount level achieved will be rounded to the unit
             level nearest to the number of units shipped. (e.g. if AGCS shipped
             65,000 ports to Paradyne during 1999 then the level achieved would
             be 75,000, if only 60,000 ports were shipped then the discount
             level achieved would be 50,000 port unit level discount).

<PAGE>   29
         Rule 3b - Calculation of the earned discount

             The earned discount will be the different between the initial
             discount applied to the ports shipped and the actual discount level
             achieved using Rule 3a. The earned discount amount is determined on
             a per Switch Product Port type basis for each order. The total
             earned discount for the order is the sum of earned discount amounts
             for each Switch Product Port type shipped with the order. If a
             credit or invoice is required, they will be issued via terms and
             conditions defined in Section 2e of this Appendix.

         Rule 3c - Earned discount on units shipped in different ED periods

             The ports in an order are given a discount level at the time the
             order was placed based on the actual number of ports shipped. The
             discount level determined at the date of order will be used for all
             ports shipped as part of that order. This applies even when the
             shipment schedule spans ED periods. Only the ports actually shipped
             in a given ED period will be used to determine the earned discount
             level.


                                      D-8
<PAGE>   30
Example 1: If Paradyne places four (4) orders throughout the year, and each
order placed contains various Switch Product types totaling 25,000 ports, the
pricing and invoicing would be as shown below: All orders were shipped within
the ED period. The discount level for all orders in the next ED period would be
at 100,000 port level.

Example 2: The earned discount level achieved in the previous period was at the
100,000 unit level. An order for 50,000 ports is placed in March 99 with a
delivery schedule over the next 12 months. However, the shipment schedule
resulted in delivery of only 25,000 ports during the ED period. Two other orders
totaling 40,000 ports were placed and shipped during the ED period. Therefore,
earned discount must be recaptured for the ED period based on Rule 3b. The
discount level for the next ED period is at the 75,000 port level using Rule 3c.

shall be amended as follows:

1.  Section 1.8 shall be deleted in its entirety and replaced by the following:

    1.8   "Revision" shall mean any correction, modification, maintenance

    21.1  Term. The initial term of this Agreement shall be five (5) years from
          the date set forth in the first sentence of this Agreement. Prior to
          the end of this term, the parties shall meet and negotiate in good
          faith an extension of this Agreement. Failing to agree upon such

3.  The following Section 21.9 shall be appended to the Agreement:

          (3) to meet product requirements of Paradyne customers who have an
          installed base of the Resale Products and require continued supply.
          Such shipments shall be subject to royalties under Schedule A except
          where termination is made necessary due to NetScout's default.
          Further, in the event royalties are paid, NetScout shall agree to
          provide reasonable continued support for bug fixes and maintenance of
          the Licensed Product. Paradyne shall further have the right to use and

                                    QUALITY


1.0  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 good will 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 Buyers 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:

1.1  QUALITY CONTROL MONITORING & SOURCE INSPECTION

     Buyer reserves the right, at any time during the term of this agreement,
with five (5) calendar days prior notice and subject to product availability,
to place one or more personnel in SELLER facilities to carry out inspection and
acceptance tests, process certifications, review of quality data, and other
functions Buyer may deem reasonably necessary to maintain quality objectives.

     Personnel authorized by Buyer shall be empowered to reject the material
intended for the delivery to Customers in the event that such material fails to
meet required specifications or acceptance tests. 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.

     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.

1.2  ACCEPTANCE TESTS

     Acceptance test procedures for final manufacturing testing and for product
acceptance purposes will be mutually agreed upon buy the Buyer and Seller.

1.3  WORKMANSHIP STANDARDS

     All Products shall be in compliance with the Buyer's workmanship
standards, IPC-A-610, as a minimum criteria of workmanship.

1.4  QUALITY CONTROL SYSTEM & ISO 9000 COMPLIANCE

     Seller shall maintain the quality control system mutually agreed upon at
the Effective Date of this contract and as specified in the Specifications.
Seller shall, with every reasonable and timely effort, apply for and/or maintain
ISO 9001 registration. Seller is expected to use its reasonable best efforts to
attain and maintain acceptable ratings resulting from any future quality system
assessments.

1.5  SELLER/BUYER CONTINUOUS IMPROVEMENT EFFORTS

     Buyer and Seller mutually agree to develop a continuous improvement plan in
an effort to reduce overall costs and improve Quality in both Processes and
Products that will mutually benefit both parties in the areas of:

     a. On Time Shipments as measured by requirements set forth in Contract.
     b. Repair Data, including DOAs, Infant mortality and Root Cause Analysis.
     c. Electronic Data Interchange (EDI).
     d. Utilizing freight carriers designated by Buyer in Buyer's Corporate
        Routing Guide.

1.6  NOTIFICATION OF QUALITY ISSUES

     Buyer is to be notified within 24 hours of catastrophic failures affecting
customer safety or equipment performance of Buyer equipment. These failures
include, but are not limited to, Product failures which greatly exceed the
normal failure rate of Buyer product, or line down conditions at SELLER which
may impact the timely shipment or quality of Buyer products. Buyer product
produced at SELLER must maintain a demonstrated confirmed DOA defect rate not
exceeding SELLER supplied MTBF calculations for Product.

1.7  CORRECTIVE ACTION FOR QUALITY ISSUES

     SELLER is expected to maintain a functioning and documented Quality system
to provide timely and effective corrective action(s) regarding quality issues.
Upon request from Buyer, SELLER is to determine the root cause of quality
defects, ensure that these defects are prevented from shipping to customers, and
provide effective corrective action to prevent the recurrence of these, or
similar, defects. Buyer reserves the right to stop shipment of Buyer product
from SELLER facilities until such actions deemed necessary to corrective the
defect have been completed.

1.8  INSPECTION AT DESIGNATED DELIVERY LOCATION

     Within 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
agreed upon Specifications. 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 lost shipping charges back to Seller and Buyer, any
insurance costs, all risk of loss [F.O.B. Destination], and 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 of this
agreement. Any Products returned under this Section of the agreement 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 of this
agreement 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, pay for the expenses associated with Buyers original
return of such Products to Seller under this Section. Notwithstanding the
foregoing, damage to Products caused by Buyer's Shipper shall not be considered
a nonconformity to the Specification.

1.9  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 installations of the Product in the

                     the Licensed Product unless authorized in writing by
                     NetScout. Notwithstanding the preceding sentence, Paradyne
                     is expressly authorized to perform whatever work is
                     necessary or advisable by NetScout to embed the Licensed
                     Product in Paradyne's FrameSaver products as defined below.
                     To the extent NetScout authorizes the development of
                     derivative works, Paradyne shall thereafter retain title to
                     the derivative work developed by or on behalf of Paradyne,
                     provided that NetScout shall retain title to the underlying
                     work upon which such derivative work is based.

     4    TITLE AND RIGHTS TO THE LICENSED PRODUCT

          4.1  The Licensed Product and Revisions to the Licensed Product are
               proprietary to NetScout, and NetScout shall retain all right,
               title and interest in and to the Licensed Product including all
               rights under applicable patents, copyrights, trademarks and
               trade secrets, and to any foreign language version of the
               Licensed Product developed or acquired by NetScout.

          4.2  NetScout represents that it has at the time of execution of this
               Agreement, and will continue to maintain during the term of this
               Agreement, the full right and authority to grant this license,
               and that neither this license nor performance under this
               Agreement does or shall conflict with any other agreement or
               obligation to which NetScout is a party or by which it is bound.

          4.3  To the extent necessary to give effect to this Agreement, the
               licenses granted to Paradyne shall include rights under any
               applicable patents, copyrights, trademarks and trade secrets
               belonging to NetScout or which NetScout has acquired or may
               acquire.

          4.4  Paradyne agrees to include NetScout's copyright notice on all

     5.   ENGINEERING REQUIREMENTS

          5.1  In consideration of Paradyne's purchase obligation as defined
               below, NetScout agrees to perform the following engineering
               services:

               5.1.1 to co-develop the revised RMON User History Group for
                     support of Paradyne's standard and enterprise MIB's;


Marketing & License Agreement     Paradyne and NetScout Confidential      page 4
NetScout and Paradyne             Use Pursuant to Company Procedures    01/26/98
<PAGE>   17

          5.1.2     to deliver the device code for RMON User History Group
                    capability prior to the alpha availability of the
                    NetScout agent code version 4.5;

          5.1.3     to deliver the updated NetScout Manager Plus Software
                    that supports configuration and graphical display of the
                    RMON User History Group capability prior to the beta
                    availability of the NetScout Manager Software, version 5.5.

          5.1.4     NetScout agrees to negotiate in good faith any engineering
                    changes requested by Paradyne which represent changes in
                    functionality of the Products not currently included in
                    NetScout's specifications and user manuals, and not
                    addressed in NetScout's future development plans may be
                    identified by NetScout under non-disclosure during business
                    reviews. NetScout's decision to incorporate any such
                    engineering changes will be primarily based on Paradyne's
                    projected sales forecast for such functionally modified
                    products and the expense to institute the proposed changes.

     5.2  NetScout further agrees to provide engineering consulting services to
          Paradyne at a rate of [***] dollars per month ($[***] month)
          during the porting of the Licensed Product into the Paradyne
          FrameSaver endpoint devices. The recommended approach for such
          engineering consulting services shall be for Paradyne to bring their
          engineering environment to NetScout's facilities to enable Paradyne's
          engineers to work more closely with NetScout's engineers and
          resources (e.g. QA, testing labs, etc.).

     5.3  Epidemic Failure. As a result of the limited purchase volumes
          forecasted during the Initial Term of the Agreement, NetScout shall
          not establish a definitive position regarding percentages, penalties
          and/or specific action plans to address "Epidemic" failures which may
          occur during the term of this Agreement. NetScout agrees, however, in
          the event that Paradyne or its Customers identify an unreasonably
          excessive amount of defective, failed or dead on arrival ("DOA")
          products during any quarterly period, to establish an action plan to
          effect an immediate remedy to the problem. NetScout further agrees to
          provide on-site technical support and all necessary parts to repair
          or replace product known to be affected by such Epidemic, and to use
          commercially reasonable efforts to ensure that the appropriate
          quality controls and other measures are taken so that all product of
          similar type supplied subsequent to the date of such an Epidemic
          shall be free from the problems which caused the Epidemic.

6.   TECHNICAL SUPPORT

      6.1  NetScout agrees to provide Tier 3 Support via a telephone
           support service as set forth in Exhibit D. The telephone support
           service will be delivered by a NetScout support person during
           NetScout's normal working hours (8 am - 6 pm, EST.), and a best
           effort paging service after hours, on weekends and holidays.
           Paradyne shall pay a fee of [***] ($[***]) annually, billed
           quarterly, for the first year of Tier 1 and 2 Support; fees for
           years 2 and 3 and any subsequent extensions of the Agreement shall
           be mutually determined thirty (30) days prior to the expiration of
           the then current year. Fee considerations shall include a range of
           [***] percent ([***]%) of install base dollar and escalation call
           volumes.

          efforts to provide written notification to Paradyne at least
          forty-five (45) days prior to any new release or new version of the
          Licensed Product, or any change in the Licensed Product that would
          materially affect its performance in the FrameSaver endpoint devices.

     6.4  NetScout will support and maintain the most current version and one
          (1) version immediately preceding the then most current version of
          the Licensed Product as modified to run in the FrameSaver end point
          devices. Such support and maintenance will be provided for the term
          of this Agreement. In the event NetScout discontinues manufacture and
          license of the Licensed Product, NetScout agrees to continue support
          and maintenance services for a period of one (1) year from such
          discontinuance.

               advanced notification, upgrade recommendations that will

               at least sixty (60) days prior to the time of the initial public
               announcement of such new product, unless other terms are mutually

               during the manufacture of the Paradyne products listed in Exhibit
               A, shall be granted to Paradyne under the following conditions:

     18.2      Discontinuance of the Licensed Products defined in Exhibit A,
               provided no functionally equivalent substituted is made available
               at or below the specified price.

     18.3      A new Licensed Product replaces or obsoletes existing Licensed

<PAGE>   24
          new Licensed Product fails to meet the specifications defined herein
          this Agreement.

     18.4 NetScout becomes insolvent. Paradyne will have the right to withdraw
          the Manufacturing Information contained in the escrow account in
          preparation for manufacturing the Products. However, such rights will

          within the time period as specified in Section 21, Termination.

     18.6 Such perpetual license will be subject to the royalties set forth in

     18.7 Notwithstanding the foregoing, the obligations of NetScout under this

          manufacturing usage licenses or other proprietary rights of third
          parties, if any, as may be required to manufacture such Product.
          NetScout agrees to provide reasonable assistance to Paradyne to
          secure such rights.

19.  LIMITATION OF REMEDIES

     19.1 Except as set forth in the Indemnity section below, NetScout's
          entire liability and Paradyne's exclusive remedy for breach of
          Section 14 shall be the replacement by NetScout of any Licensed
          Product which fails to meet NetScout's Limited Warranty defined in
          such section. Neither party shall have any liability for special,
          incidental or consequential damages, including lost profits, arising
          out of this Agreement or with respect to the installation, use
          operation or support of the Licensed Product and Resale Products,
          even if such party has been apprised of the possibility of such
          damages.

     19.2 Except as set forth in the Indemnity section below, either party's
          total liability arising from breach of warranty, breach of contract,

          paid and Resale Products purchased by Paradyne, and (ii) ____________
          dollars ($_________). This limitation of liability shall not apply to
          personal injury or direct damage resulting from claims of gross
          negligence or willful misconduct, provided the injured party asserts
          a right to recover those direct damages from the other Party.

20.  INDEMNIFICATION

     20.1 NetScout shall defend, hold harmless and indemnify Paradyne and its
          Customers from and against any claim that NetScout's Licensed
          Product, Resale Products and Documentation (collectively the
          "Materials") supplied or licensed hereunder infringe any patent,
          copyright, trade secret, trademark or other intellectual property
          rights of a third party, and NetScout will pay the costs and damages
          related thereto, including, without limitation, reasonable attorneys'
          fees, provided that: (a) Paradyne promptly notifies NetScout in
          writing of the claim; and (b) NetScout has sole control of the
          defense and all related settlement negotiations.

     20.2 The obligation of NetScout under paragraph 1 of this Section 20 is
          conditioned on Paradyne's agreement that if the Materials or the
          operation thereof, become, or in the opinion of NetScout, are likely
          to become, the subject of such a claim, that Paradyne will permit
          NetScout, at the sole option and expense of NetScout, either

          to procure the right for Paradyne to continue marketing and
          distributing the Materials or to replace or modify them so that they
          become non-infringing, provided that such replacement or modification
          does not materially degrade the performance or functionality of the
          Materials NetScout shall have no liability for any claim based upon
          the combination or use of any of the Materials supplied hereunder with
          equipment, data or programming not supplied by NetScout, or based upon
          alteration or modification of NetScout's Material by Paradyne,
          provided the liability would not arise absent the combination,
          alteration or modification.

    20.3  The foregoing states the entire obligation of NetScout to Paradyne
          with respect to infringement of patents, copyrights and trade secrets,

    21.1  Term. The initial term of this Agreement shall be three (3) years from
          the date set forth in the first sentence of this Agreement.

          ninety (90) days advance written notice to the other party.

    21.2  If either party ceases doing business as a going concern, becomes
          insolvent, suffers or permits the appointment of a receiver for its
          business or assets or shall avail itself of, or become subject to, any

          any statute of any state relating to insolvency or the protection of
          rights of creditors, then (at the option and upon noticed from the
          other party) this Agreement shall terminate and be of no further force
          and effect.

    21.4  In the event either party defaults any obligations in this Agreement,
          the other party shall give written notice of such default, and, if the

          certification in writing that the Source Code and any copies thereof
          have been destroyed. TERMINATION SHALL NOT RELIEVE PARADYNE OR
          NETSCOUT OF ITS OBLIGATIONS REGARDING THE CONFIDENTIALITY IN ANY
          LICENSED PRODUCT(S).

    21.6  Without limiting any of the provisions contained in the preceding
          paragraphs of this section, in the event of termination as a result of
          Paradyne's failure to comply with any of its obligations under this
          Agreement, Paradyne shall continue to be obligated for any payments

22   ARBITRATION

     22.1   Any controversy or claim, whether based on contract, tort, or other
            legal theory (including, but not limited to, any claim of fraud or
            misrepresentation), arising out of or related to this Agreement
            shall be resolved by arbitration pursuant to this Paragraph and
            the then current rules and supervision of the American Arbitration
            Association. The duty to arbitrate shall extend to any officer,
            employee, agent, or subsidiary making or defending any claim which
            would otherwise be arbitrable hereunder. The arbitration shall be
            held in the headquarters city of the party not initiating the claim
            before a single arbitrator who is knowledgeable in business
            information and electronic data processing systems. The
            arbitrator's decision and award shall be final and binding and may
            be entered in any court having jurisdiction thereof. The arbitrator
            shall not have the power to award punitive or exemplary damages.
            Issues of arbitrability shall be determined in accordance with the
            federal substantive and procedural laws relating to arbitration; all
            other aspects shall be interpreted in accordance with the laws of
            the State of New York. Each party shall bear its own attorney's
            fees associated with the arbitration and other costs and expenses
            of the arbitration shall be borne as provided by the rules of the
            American Arbitration Association. If court proceedings to stay
            litigation or compel arbitration are necessary, the party who
            unsuccessfully opposes such proceedings shall pay all associated
            costs, expenses and attorney's fees which are reasonably incurred
            by the other party. If any portion of this Paragraph is held to be
            unenforceable, it shall be served and shall not affect either the
            duty to arbitrate hereunder or any other part of this Paragraph.

23.  GENERAL

            performed under this Agreement shall comply with all applicable
            United States and foreign laws and regulations. Either party's

            result in a material breach of this Agreement.

     23.3   Assignment: Either party 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 upon written
            notice to the non-assigning party and without the non-assigning
            party's consent.

            Upon an assignment by either party and with thirty days prior
            written notice the non-assigning party may terminate the Agreement
            in the event that the assignee, in the non-assigning party's
            reasonable opinion, is a competitor of the non-assigning party or
            is of questionable financial stability and/or soundness.

           diminish any rights or duties that either party may then or
           thereafter have as to Products, Licensed Materials or Services
           delivered prior to the effective date of this assignment. Upon the
           assumption of the duties under this Agreement by the assignee, the
           assigning party shall be released and discharged, to the extent of
           the assignment, from all further duties under this Agreement as to

           signed and accepted by an authorized representative of each Party,
           and no Party shall be bound by any change, alteration, amendment,
           modification, termination or attempted waiver of any of the
           provisions hereof unless in writing and signed by an authorized
           representative of the Party against whom it is sought to be enforced.
           This Agreement shall be binding on and inure to the benefit of the
           Parties hereto and their prospective successors, legal
           representatives and permitted assigns.

     23.5  Nonwaiver.

           23.5.1 All rights and remedies conferred by this Agreement, by any
                  other instrument, or by law are cumulative and may be
                  exercised singularly or concurrently. If any provision of this
                  Agreement is held invalid by any law or regulation of any
                  government or by any court, such invalidity shall not affect
                  the enforceability of any other provisions hereof.

           23.5.2 No forbearance, delay or indulgence by either party in
                  enforcing the provisions of this Agreement shall prejudice or
                  restrict the rights of that party nor shall any waiver of its
                  rights operate as a waiver of any subsequent breach and no
                  right, power or remedy herein conferred upon or reserved for
                  either party is exclusive of any other right, power or remedy
                  available to the Party and each such right, power or remedy
                  shall be cumulative.

           23.5.3 Either Party may seek injunction preliminary or other
                  equitable relief to remedy any actual or threatened dispute.

     23.6  Independent Contractor. The relationship between the Parties is that
           of independent contractors, and under no circumstances shall any of
           the employees of one party be deemed to be employees of the other
           party for any purpose. Except as specifically provided herein, this
           Agreement shall not be construed (a) as authority for either party to
           act for the other in an agency or any other capacity, or to make
           commitments of any kind for the account of or on behalf of the other
           or (b) to imply that Paradyne is an agent of NetScout as defined by

                               AMENDMENT NO. 2 TO
                          LOAN AND SECURITY AGREEMENT


     THIS AMENDMENT NO. 2 TO LOAN AND SECURITY AGREEMENT ("Amendment") is dated
as of March 17, 1999 and is entered into by and between BankAmerica Business
Credit, Inc. ("Lender") and Paradyne Corporation ("Borrower"). All capitalized
terms used herein but not otherwise defined shall have the meanings ascribed to
them in the Agreement (as hereinafter defined).


                                   WITNESSETH

     WHEREAS, the Borrower and the Lender have entered into that certain Loan
and Security Agreement dated as of July 31, 1996, as amended and supplemented
(the "Agreement"); and

     WHEREAS, the Borrower desires to amend the Agreement and the Lender is
willing to do so, subject to the terms and conditions stated herein;

     NOW, THEREFORE, in consideration of the premises herein contained and
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the Borrower and Lender hereby agree as follows:

     Section 1.  Amendment to the Agreement. The Lender and Borrower agree that
the Agreement shall be amended as follows:

          A.   Amendment to Section 1. The definition of "Availability"
     contained in Section 1 of the Agreement is amended by deleting the words
     "Forty-Five Million Dollars ($45,000,000)" and inserting in lieu thereof
     the words "Thirty-Five Million Dollars ($35,000,000)".

          B.   Amendment to Section 2. The first sentence of Section 2.1 of the
     Agreement is amended to read as follows:

               "Subject to all of the terms and conditions of this Agreement,
          the Lender shall make available a total credit facility of up to
          $35,000,000 (the 'Total Facility') for Borrower's use from time to
          time during the term of this Agreement."

          C.   Amendment to Section 3. Section 3.3 of the Agreement is amended
     to read as follows:

               "3.3  Unused Line Fee. For every month during the term of this
          Agreement, the Borrower shall pay the Lender a fee (the 'Unused Line
          Fee') in an amount equal to: (i) during any month that the amount
          determined under (y) below is equal to or greater than $15,000,000,
          three-eighths percent (0.375%) per annum, or (ii) during any month
          that the amount



                                      -1-

<PAGE>   2

          determined under (y) below is less than $15,000,000, one-half percent
          (0.50%) per annum, multiplied by the average daily amount by which (x)
          $35,000,000 exceeded (y) the sum of (a) the average daily outstanding
          amount of Revolving Loans and (b) the average daily undrawn face
          amount of all outstanding Letters of Credit during such month, with
          the unpaid balance of Revolving Loans calculated for this purpose by
          applying payments immediately upon receipt. The Unused Line Fee, if
          any, shall be calculated on the basis of a year of three hundred
          sixty (360) days and actual days elapsed, and shall be payable to the
          Lender on the first day of each month with respect to the prior
          month."

     Section 2.  Conditions.  The effectiveness of this Amendment is subject to
the satisfaction of the following conditions precedent:

          A.  Amendment. Fully executed copies of this Amendment signed by the
     Borrower and a ratification signed by the Guarantor shall be delivered to

          C.  Other Documents.  Borrower shall have executed and delivered to
     Lender such other documents and instruments as Lender may require.

     Section 3.  Miscellaneous.

          A.  Survival of Representations and Warranties. All representations
     and warranties made in the Agreement or any other document or documents
     relating thereto, including, without limitation, any Loan Document
     furnished in connection with this Amendment, shall survive the execution
     and delivery of this Amendment and the other Loan Documents, and no
     investigation by Lender or any closing shall affect the representations and
     warranties or the right of Lender to rely thereon.

          B.  Reference to Agreement.  The Agreement, each of the Loan
     Documents, and any and all other agreements, documents or instruments now
     or hereafter executed and delivered pursuant to the terms hereof, or
     pursuant to the terms of the Agreement as amended hereby, are hereby
     amended so that any reference therein to the Agreement shall mean a
     reference to the Agreement as amended hereby.

          C.  Agreement Remains in Effect.  The Agreement and the Loan
     Documents remain in full force and effect and the Borrower ratifies and
     confirms its agreements and covenants contained therein. The Borrower
     hereby confirms that, after giving effect to this Amendment, no Event of
     Default or Default exists as of such date.

          D.  Severability. Any provision of this Amendment held by a court of
     competent jurisdiction to be invalid or unenforceable shall not impair or
     invalidate the



                                      -2-

     remainder of this Amendment and the effect thereof shall be confined to the
     provision so held to be invalid or unenforceable.

          F.  Successors and Assigns.  This Amendment is binding upon and shall
     inure to the benefit of Lender and Borrower and their respective successors
     and assigns; provided, however, that Borrower may not assign or transfer
     any of its rights or obligations hereunder without the prior written
     consent of Lender.

          G.  Counterparts. This Amendment may be executed in one or more
     counterparts, each of which when so executed shall be deemed to be an
     original, but all of which when taken together shall constitute one and
     the same instrument.

          H.  Headings.  The headings, captions and arrangements used in this
     Amendment are for convenience only and shall not affect the interpretation
     of this Amendment.

          I.  NO ORAL AGREEMENTS.  THIS AMENDMENT, TOGETHER WITH THE OTHER LOAN
     DOCUMENTS AS WRITTEN, REPRESENTS THE FINAL AGREEMENT BETWEEN LENDER AND
     BORROWER AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS
     OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
     AGREEMENTS BETWEEN LENDER AND BORROWER.

     IN WITNESS WHEREOF, the parties have executed this Amendment under seal on
