     This summary highlights certain information contained elsewhere in this
prospectus. This summary is not complete and does not contain all of the
information you should consider before investing in our common stock. You should
read the entire prospectus carefully, especially the risks of investing in our
common stock discussed under "Risk Factors."

                       AIRNET COMMUNICATIONS CORPORATION


     We provide cellular base stations and other wireless telecommunications
infrastructure products designed to support the GSM, or Global Standard for
Mobile Communications, system of mobile voice and data transmission. We market
our products to operators of cellular and other wireless networks. A base
station is a key component of a wireless network and is used to receive and
transmit voice and data signals over radio frequencies. Our products include the
AdaptaCell, a software-defined base station, meaning it uses software to control
the way it encodes or decodes wireless signals, and the AirSite, a backhaul free
base station, meaning it carries voice and data signals back to the wireline
network without using a physical communications link.



     Our AdaptaCell incorporates a proprietary radio architecture that is
designed to enable operators to upgrade their wireless networks to offer
high-speed data and Internet services by changing software rather than deploying
new base stations. Our AdaptaCell also incorporates a broadband architecture,
meaning that it uses only one radio to process a large number of radio channels.
Our AirSite uses an operator's existing radio frequencies as the medium to
provide the necessary connection to the wireline network. We believe our key
product attributes make our base stations easier to deploy and upgrade and
result in lower capital and operating costs than other existing base stations.
We received the 1998 GSM World Award for Best Technical Innovation from the GSM
Association, an international body with members from 133 countries, in
recognition of our revolutionary infrastructure.



     In recent years, there has been substantial growth in the number of
wireless users around the world. According to International Data Corporation, or
IDC, there were over 303 million wireless subscribers worldwide in 1998 and
approximately 44% of these subscribers were using GSM. According to Allied
Business Intelligence Inc., at the end of 1998, there were 3 million GSM
subscribers in the United States, representing 4.3% of all wireless subscribers
in the United States. IDC estimates that the number of wireless users worldwide
will reach approximately 1.1 billion in 2003, representing a 29% compound annual
growth rate, and GSM wireless users worldwide will reach 557 million by the end
of 2003, representing a 33% compound annual growth rate. We expect increasing
demand for high speed data and wireless Internet services to contribute to this
growth.



     We expect this growth will require wireless service operators to deploy
infrastructure equipment capable of addressing existing wireless standards and a
new generation of wireless standards now under development. Existing GSM base
stations were not designed to be compatible with these developing standards. As
a result, we believe many wireless operators will replace their existing
hardware with more flexible, upgradeable base stations.



     We believe our wireless infrastructure products position us to meet the
industry's challenge of transitioning from existing GSM networks to emerging
integrated voice and high-speed data networks. Due to the uncertainty of the
timing of this transition, our products have been designed to appeal to
operators who desire a wireless solution today with the ability to adapt to
tomorrow's new communications standards.



     The AdaptaCell and the AirSite Backhaul Free Base Station provide the
following key benefits:



          Adaptable and Easy to Upgrade.  We designed our software-defined
     AdaptaCell base station to support new wireless standards through changes
     in software, and few, if any, hardware modifications. By contrast, other
     existing base stations must be extensively modified or even replaced if
     operators want to offer high-speed data services to their customers.


                                        1
<PAGE>   7


          Lower Operating Costs.  Our AirSite does not require an expensive
     physical communications link, usually through a digital T-1 phone line, to
     the wireline network. Our AdaptaCell's simplified hardware design results
     in a smaller base station that has fewer components and is easier to
     install and maintain.



          Flexible Deployment.  Our system is scaleable and allows operators to
     start small, establish a network, and incrementally expand coverage and
     capacity as subscriber demand increases.



     Our goal is to become a leading worldwide supplier of wireless base
stations. Our strategy for achieving this goal includes the following core
elements:



     - leveraging our technology leadership;



     - continuing to market our product advantages to domestic operators;



     - expanding into international markets; and



     - establishing a market leadership position in the emerging high-speed data
       base station market.



                                  RISK FACTORS



     Our business involves a high degree of risk. The principal risks are
described under "Risk Factors" and "Special Note Regarding Forward-Looking
Statements." Among these are the following:



     - we have incurred losses of $95.1 million through September 30, 1999 and
       expect to continue to incur substantial losses;



     - we have only a limited operating history and have generated only $19.7
       million in net revenues through September 30, 1999 and have only five
       commercial deployments to date; and



     - we may not be able to modify our base stations to support some of the
       developing wireless standards.



     We are incorporated in Delaware. Our executive offices are located at 100
Rialto Place, Suite 300, Melbourne, Florida 32901 and our telephone number is
(407) 953-6600.

                                  RISK FACTORS

     Before you invest in our common stock, you should be aware that there are
various risks, including those described below. You should consider carefully
these risk factors together with all of the other information included in this
prospectus before you decide to purchase shares of our common stock.


     WE HAVE INCURRED SIGNIFICANT LOSSES SINCE WE BEGAN DOING BUSINESS,
ANTICIPATE CONTINUING LOSSES, AND MAY NEVER ACHIEVE OR SUSTAIN
PROFITABILITY.  We have accumulated losses of $95.1 million since we began doing
business in 1994 through September 30, 1999, and we may never achieve or sustain
profitability. We will need to generate significantly higher revenues to achieve
and sustain profitability. Since we began doing business in 1994, we have
generated only $19.7 million in net revenues through September 30, 1999. We have
been marketing our GSM base stations since 1996, and to date our only meaningful
sales have been to a small number of start-up domestic wireless operators. We
have never reported a profit. We will continue to incur significant research and
product development, sales and marketing, materials and general administrative
expenses. We anticipate a net loss for the year 1999 and we may continue to
incur losses beyond 1999. We cannot be certain that we will realize sufficient
revenues or margins to sustain our business.



     WE HAVE A LIMITED OPERATING HISTORY ON WHICH TO BASE YOUR INVESTMENT
DECISION AND WE CANNOT PREDICT FUTURE RESULTS.  We have a limited operating
history and you should not rely on our recent results as an indication of our
future results in making your investment decision. There have been only five
commercial deployments of our systems to date. We had net sales of only $1.1
million, $1.6 million and $4.5 million in 1996, 1997 and 1998, respectively, and
$11.1 million for the nine months ended September 30, 1999. Unless we can
achieve significant increases in market acceptance of our products, we may never
advance beyond our start-up phase. Due to our limited operating history, it is
difficult or impossible for us to predict future results and you should not
expect future revenue growth based on our recent results. You should consider
our business and prospects in light of the risks and problems faced by
technology companies in the early stages of development.



     OUR LENGTHY AND VARIABLE SALES CYCLE MAKES IT DIFFICULT FOR US TO PREDICT
IF AND WHEN A SALE WILL BE MADE AND COULD CAUSE US OPERATING DIFFICULTIES AND
CASH FLOW PROBLEMS.  Our sales cycle, which is the period from the generation of
a sales lead until the recognition of revenue, can be long and is unpredictable,
making it difficult to forecast revenues and operating results. Our inability to
accurately predict the timing and magnitude of our sales could cause a number of
problems:


     - we may have difficulty meeting our customers' delivery requirements in
       the event many large orders are received in a short period of time
       because we have limited production capacity and generally do not carry
       materials in inventory;

     - we may expend significant management efforts and incur substantial sales
       and marketing expenses in a particular period that do not translate into
       orders during that period or at all; and

     - we may have difficulty meeting our cash flow requirements and obtaining
       credit because of delays in receiving orders and because the terms of our
       customer contracts defer certain billings until post-shipment contractual
       milestones are met.

     The problems resulting from our lengthy and variable sales cycle could
impede our growth, harm our stock price, and restrict our ability to take
advantage of new opportunities.


     WE EXPECT OUR QUARTERLY REVENUES AND OPERATING RESULTS TO FLUCTUATE
SIGNIFICANTLY WHICH COULD CAUSE OUR STOCK PRICE TO FLUCTUATE.  Our quarterly
revenues and operating results have varied and are likely to continue to vary
significantly due to the other risk factors described in this section and our
revenue recognition policy. While we may ship products on a regular basis as
they are manufactured for a customer, we presently record revenue only after
resolution of any uncertainties regarding satisfaction of all significant terms
and conditions of the customer contract. Given our limited operating history,
such uncertainties have been considered resolved to date when the customer has
placed the products in service or completed specified testing procedures. A
number of different factors outside our control can delay


                                        5
<PAGE>   11


satisfaction of these conditions. Since our products are typically deployed as
part of a complete wireless system and we often fulfill orders through multiple
shipments, customers must have received the final shipment in order to either
place our products in service or complete the specified testing procedures. As
of September 24, 1999, the time period between shipment and revenue recognition
has averaged approximately 100 days, but has varied widely, and in one case was
as long as 225 days. In addition, because we do not maintain an inventory of
materials or finished goods and there is significant variation in the
manufacturing lead times for our components, shipment for our product typically
occurs 90 days after receipt of an order from a new customer. Our operating
results may be below the expectations of public market analysts and investors.
If this occurs, our stock's trading price could significantly decline.



     INTENSE COMPETITION IN THE MARKET FOR WIRELESS TELECOMMUNICATIONS EQUIPMENT
FROM MANY LARGER, MORE ESTABLISHED COMPANIES WITH GREATER RESOURCES COULD
PREVENT US FROM INCREASING OUR REVENUE AND ACHIEVING PROFITABILITY.  The
wireless telecommunications infrastructure market is highly competitive. We
compete with large infrastructure manufacturers, systems integrators, and base
station subsystem suppliers, as well as new market entrants. Most of our current
and potential competitors have longer operating histories, larger installed
customer bases, substantially greater name recognition, and more financial,
technical, manufacturing, marketing, sales, distribution and other resources
than we do. We may not be able to compete successfully against current and
future competitors, including companies that develop and market new wireless
telecommunications products and services. These competitive pressures may result
in price reductions, reduced gross margins, longer sales cycles and loss of
customers.



     OUR INABILITY TO PROVIDE FINANCING FOR OUR CUSTOMERS IS A COMPETITIVE
DISADVANTAGE AND COULD RESULT IN A LOSS OF SALES AND/OR CUSTOMERS TO COMPETITORS
WITH GREATER RESOURCES.  Due to our size, we do not offer financing to our
customers which could cause us to lose business to our larger competitors. Many
of our customers and potential customers are start-up and small companies. These
operators usually require debt or equity financing to operate their businesses
and to purchase our products, and unlike some of our larger competitors, we are
not in a position to provide product purchase financing. Because we do not
provide this financing and have no plans to do so in the future, our success may
depend significantly upon our continuing ability to help arrange financing for
our customers. If we cannot assist in arranging financing for our customers, we
may lose sales and customers to competitors that directly provide financing.



     IF WE PROVIDE CUSTOMER FINANCING IN THE FUTURE, CREDIT RISK PROBLEMS COULD
HURT OUR RESULTS AND REQUIRE US TO RAISE ADDITIONAL CAPITAL.  In the future, we
may attempt to provide product purchase financing for our customers. If we
provide such financing, we will face credit risks, including slow payments or
non-payments from customers, and we may need to raise additional capital to
support financed sales and to deal with related credit risk problems.



     A SMALL NUMBER OF CUSTOMERS ACCOUNT FOR SUBSTANTIALLY ALL OF OUR REVENUES
AND THE LOSS OF ANY OF THESE CUSTOMERS COULD HURT OUR RESULTS AND CAUSE OUR
STOCK PRICE TO DECLINE.  Our customer base has been and may continue to be
concentrated with a small number of customers. The loss of any of these
customers or the delay, reduction or cancellation of orders by or shipments to
any of these customers could hurt our results and cause a decline in our stock
price. In 1998, three customers accounted for 96% of our net revenues, with one
accounting for 42%. For the nine months ended September 30, 1999, two customers
accounted for 76% of our net revenues, with one accounting for 48%. The effect
of these risks on our operating results is compounded by our lengthy sales
cycle.



     WE HAVE A CONCENTRATED CUSTOMER BASE AND THE FAILURE OF ANY OF OUR
CUSTOMERS TO PAY US OR TO PAY US ON TIME COULD CAUSE SIGNIFICANT CASH FLOW
PROBLEMS, HURT OUR RESULTS AND CAUSE OUR STOCK PRICE TO DECLINE. Our
concentrated customer base significantly increases the credit risks associated
with slow payments or non-payments by our customers. These risks are also higher
for us since many of our customers are start-up and small companies. Two
customers accounted for 82% of our outstanding accounts receivable as of
September 30, 1999, with one customer representing 61%. Two customers
represented 97% of our outstanding accounts receivable as of December 31, 1998,
with one customer representing 58%. In the past we have incurred bad debt
charges and we may be required to do so in the future. The failure of any of


                                        6
<PAGE>   12


our customers to pay us, or to pay us on time, could cause significant cash flow
problems, hurt our results and cause our stock price to decline.



     WE HAVE DEVELOPED A SINGLE PRODUCT LINE BASED ON THE GSM STANDARD AND WE
MAY NOT SUCCEED IF GSM IS NOT WIDELY ACCEPTED IN THE U.S.  We are concentrating
our efforts on the development and sale of a single product line of GSM base
station systems and related products. GSM, or the Global System for Mobile
Communication wireless standard, was first commercially deployed in the U.S.,
our current principal market, in late 1995. According to Allied Business, at the
end of 1998 the U.S. had 3.0 million GSM subscribers, compared to 13.9 million
users of other digital standards, including CDMA, or code division multiple
access, and TDMA, or time division multiple access. Additionally, there were
49.6 million analog subscribers in the U.S. at the end of 1998. These other
standards are more established in the U.S. and some in the industry perceive
CDMA to have several operational advantages over GSM, including greater
capacity. If GSM is not widely accepted by domestic wireless subscribers and if
we do not gain acceptance in our initial target market, our plans to sell
products abroad or in other targeted markets could be harmed. We have no backup
or alternative products in the event we are unsuccessful at selling our
currently planned GSM product line.



     IF WE DO NOT SUCCEED IN THE DEVELOPMENT OF NEW PRODUCTS AND PRODUCT
FEATURES IN RESPONSE TO CHANGING TECHNOLOGY AND STANDARDS, CUSTOMERS WILL NOT
BUY OUR PRODUCTS.  We need to develop new products and product features in
response to the evolving demands for better technology or our customers will not
buy our products. The market for our products is characterized by rapidly
changing technology, evolving industry standards, emerging wireless transmission
standards, and frequent new product introductions and enhancements. Our success
depends on our ability to adapt and upgrade our base stations to allow operators
to offer high-speed data and Internet services. If we fail to develop our
technology, we will lose significant potential market share to our competitors.
Also, because some operators do not have sufficient licensed spectrum, some of
our potential customers may not migrate to higher speed standards and those who
do may not purchase any of our products for use with new standards.



     WE MAY NOT BE ABLE TO MODIFY OUR BASE STATIONS TO SUPPORT SOME OF THE
DEVELOPING WIRELESS STANDARDS AND THAT COULD SERIOUSLY HARM OUR BUSINESS.  Our
base stations do not yet support emerging high speed data standards. We will
incur significant research and development costs to develop upgrade packages to
make our base stations compatible with them. We cannot predict with certainty
that we will be able to meet the technical demands of some of these new
standards, and if we are not successful, our business could be seriously harmed.
Even if we do develop our technology and products to work with these new
standards, consumer demand for advanced wireless services may not be sufficient
to justify network operators upgrading to them.



     WE MAY NOT BE ABLE TO ADEQUATELY PROTECT OUR PROPRIETARY RIGHTS WHICH WOULD
HURT OUR ABILITY TO COMPETE.  Although we attempt to protect our intellectual
property rights through patents, trademarks, trade secrets, copyrights,
confidentiality and nondisclosure agreements and other measures, intellectual
property is difficult to evaluate and these measures may not provide adequate
protection for our proprietary rights and information. Patent filings by third
parties, whether made before or after the date of our filings, could render our
intellectual property less valuable. Competitors may misappropriate our
proprietary rights and information, disputes as to ownership of intellectual
property may arise, and our proprietary rights and information may otherwise
become known or independently developed by competitors. The failure to protect
our proprietary rights could seriously harm our business, operating results and
financial condition. We have not been granted any foreign patents and presently
have only a relatively low number of patent applications pending
internationally. If we do not obtain sufficient international protection for our
intellectual property, our competitiveness in international markets could be
significantly impaired, which would limit our growth and future revenues.


     OTHERS MAY BRING INFRINGEMENT CLAIMS AGAINST US THAT COULD BE
TIME-CONSUMING AND EXPENSIVE TO DEFEND.  In the future, claims of infringement
of other parties' proprietary rights, invalidity claims or claims for
indemnification resulting from infringement claims may be asserted or prosecuted
against us. Even if none of these claims were valid or successful, we would be
forced to incur significant costs and

                                        7
<PAGE>   13

divert important resources to defend against them. Any claim of infringement,
whether or not successful, could cause us considerable expense and place a
significant burden on our management.


     A SIGNIFICANT DECREASE IN THE COST OF DIGITAL T-1 PHONE LINES WILL DIMINISH
ONE OF OUR COMPETITIVE ADVANTAGES.  Existing base stations require an expensive
physical communications link, usually through a digital T-1 phone line, to the
wireline network. Any significant decrease in the cost of digital T-1 phone
lines used to connect base stations to the wireline network, especially in less
populated areas, will diminish a cost advantage that we currently use to market
our products. The cost of T-1 facilities has recently declined significantly in
urban areas because of increased competition and increased market penetration of
DSL, or digital subscriber line, technologies.



     IF WE FAIL TO EXPAND OUR CUSTOMER BASE BEYOND THE SMALLER OPERATORS WHO
RECENTLY ACQUIRED FCC LICENSES, WE MAY NOT BE ABLE TO SIGNIFICANTLY GROW OUR
REVENUES.  We will only be able to significantly grow our revenues if we can
expand our customer base beyond the smaller operators who recently acquired FCC
licenses. There are a limited number of such operators and most of them are
smaller companies with limited resources. These operators are less stable and
more susceptible to delays in their buildouts and deployments than more
established operators. We plan on expanding our sales to include the larger
domestic operators and international operators. However, as a result of the
rapid consolidation of larger domestic GSM operators, there are only a few
larger domestic operators remaining. To date we have not had any sales to the
larger domestic or any international operators, and we may not be successful in
those markets in the future.


     WE PLAN TO EXPAND INTO INTERNATIONAL MARKETS, WHICH WILL SUBJECT US TO
ADDITIONAL BUSINESS RISKS. Because the U.S. market for GSM products is
comparatively small, we have begun marketing our products internationally. A
portion of our international sales efforts will be targeted to service operators
who plan to deploy wireless communications networks in developing countries
where risks ordinarily associated with international operations are particularly
acute. International operations are subject to a number of risks and
uncertainties, including:

     - difficulties and costs associated with obtaining foreign regulatory
       approval for our products;

     - unexpected changes in regulatory requirements;

     - difficulties and costs associated with complying with a wide variety of
       complex foreign laws and treaties;

     - legal uncertainties regarding, and timing delays and expenses associated
       with, tariffs, export licenses and other trade barriers;

     - inadequate protection of intellectual property in foreign countries;

     - increased difficulty in collecting delinquent or unpaid accounts;

     - lack of suitable export financing;

     - adverse tax consequences;

     - dependence upon independent sales representatives and other indirect
       resellers who may not be as effective and reliable as our employees;

     - difficulties and costs associated with staffing and managing
       international operations, overcoming cultural, linguistic and
       nationalistic barriers and adapting to foreign business practices;

     - political and economic instability; and

     - currency fluctuations, including a decrease in the value of foreign
       currencies relative to the U.S. dollar which could make our products less
       competitive against those of foreign competitors.

Any of these factors could impair our ability to expand into international
markets and could prevent us from increasing our revenues and achieving
profitability.

     IF WE HAVE PROBLEMS CONNECTING TO OUR COMPETITORS' MOBILE TELEPHONE
SWITCHES, WE WILL INCUR ADDITIONAL EXPENSE AND DELAYS IN SELLING OUR PRODUCTS
AND MAY LOSE SALES.  Our products must be compatible with our competitors'
mobile telephone switches. Although GSM is based on a number of well-defined
standard interfaces, a GSM switch can be manufactured according to different
variations within the standard interface. As a result, we may encounter
obstacles when we attempt to integrate our products with a particular switch,
since we have not yet tested our products for compatibility with all vendors'
switches. If we have problems connecting our products to a particular switch, we
will incur additional expense and delays in selling our products and may lose
sales.



     OUR RELIANCE ON A LIMITED NUMBER OF SUPPLIERS COULD LEAD TO DELAYS,
ADDITIONAL COSTS, PROBLEMS WITH OUR CUSTOMERS AND POTENTIAL CUSTOMERS, AND LOSS
OF REVENUE.  We plan to continue utilizing only one or a small number of
suppliers for each of the components of our base station systems. In particular,
there is currently only one supplier of high power amplifiers, a critical
component for a broadband base station, that can provide us with a product that
meets our quality standards. Furthermore, the majority of the switches used with
our systems have been manufactured by one of two small third party vendors. We
have no long-term contracts or arrangements with any of our suppliers that
guarantee product availability or the continuation of particular payment or
credit terms. If, for any reason, a supplier fails to meet our quality and
quantity requirements or stops selling products to us at commercially reasonable
prices, we could experience significant production delays and cost increases, as
well as higher warranty expenses and product image problems. Any of these
problems could damage relationships with current or prospective customers which
could seriously harm our operating results in a given period and impair our
ability to generate future sales. From time to time, we must replace some of the
components of our products when the supplier of that component is discontinuing
production. While we generally do not maintain an inventory of components,
sometimes we do purchase an inventory of these discontinued components so that
we can maintain production while finding new suppliers or developing substitute
components ourselves. We face the risk that we may deplete that inventory before
finding an adequate substitute, and that could cause the loss of significant
sales opportunities. Alternatively, we could purchase too many of the components
and may be left with excess inventory on our hands. We generally do not maintain
an inventory of finished goods and many components have long lead times, with
some taking 12 to 16 weeks from the time of entry of the order to delivery. We
cannot guarantee that alternative sources of supply can be arranged on short
notice or that components will be available from alternative sources on
satisfactory terms.



     IF WE LOSE KEY PERSONNEL OR ARE UNABLE TO HIRE ADDITIONAL QUALIFIED
PERSONNEL, WE MAY NOT BE SUCCESSFUL. Our future success largely depends on our
ability to attract and retain highly-skilled hardware and software engineers,
particularly call processing engineers and digital signal processing engineers.
The market for these engineers is highly competitive and if we cannot continue
to attract and retain quality personnel, that failure would significantly limit
our ability to compete and to grow our business. Our success also depends upon
the continuing contributions of our key management, research, product
development, sales and marketing and manufacturing personnel, many of whom would
be difficult to replace, including R. Lee Hamilton, Jr., President and Chief
Executive Officer. Except for a severance and noncompetition agreement we have
with Dr. Hamilton, we do not have employment or noncompetition agreements with
any of our key officers. We also do not have key man life insurance policies
covering any of our employees.



     IF WE FAIL TO MANAGE OUR GROWTH AND EXPANSION EFFECTIVELY, OUR BUSINESS AND
PROSPECTS COULD BE SERIOUSLY HARMED.  The need to develop and offer our products
and implement our business plan in an evolving market will significantly
challenge our planning and management capabilities. At September 30, 1999, we
had a total of 153 employees. We plan to hire a significant number of new
employees as we expand our operations. We may not be able to implement
management information and control systems in an efficient and timely manner,
and our current or planned personnel, systems, procedures and controls may not
be adequate to support our future operations. If we are unable to manage our
growth effectively,


                                        9
<PAGE>   15

our business and prospects could be seriously harmed. To manage our expected
growth of operations and personnel, we will need to:

     - improve financial and operational controls, as well as our reporting
       systems and procedures;

     - install new management information systems; and

     - hire, train, motivate and manage our sales and marketing, engineering,
       technical, finance and customer support employees.


     WE HAVE AN AGREEMENT WITH MOTOROLA, INC. TO GRANT THEM RIGHTS WHICH COULD
HARM OUR BUSINESS. When Motorola purchased $10.0 million of our Series B
Preferred Stock in 1995, we granted Motorola the right to acquire a worldwide,
nonexclusive, royalty-free license under any two of our patents. Motorola is a
large telecommunications and technology company with significant resources and
could exercise this right at any time and begin using these licenses to compete
against us. With respect to any possible infringement of our respective digital
base station patents, each of us also agreed not to enjoin the other and to
attempt dispute resolution, including negotiation of nonexclusive license
agreements in good faith, before resorting to litigation.



     WE EXPECT THE PRICES OF OUR PRODUCTS TO DECLINE DUE TO COMPETITIVE
PRESSURES, AND THIS DECLINE COULD REDUCE OUR REVENUES AND GROSS MARGINS.  We
anticipate that the prices of our products will decrease in the future due to
competitive pricing pressures, increased sales discounts, new product
introductions or other factors. If we are unable to offset these factors by
increasing our sales volumes, our revenues will decline. In addition, to
maintain our gross margins, we must develop and introduce new products and
product enhancements, and we must continue to reduce the manufacturing costs of
our products. We cannot guarantee that we will be able to do these things
successfully. Our failure to do so would cause our revenue and gross margins to
decline, which could seriously harm our operating results and cause the price of
our common stock to decline.



     WE MAY ENGAGE IN FUTURE ACQUISITIONS THAT DILUTE OUR STOCKHOLDERS, CAUSE US
TO INCUR DEBT OR ASSUME CONTINGENT LIABILITIES AND SUBJECT US TO OTHER
RISKS.  We expect to review opportunities to buy other businesses or
technologies that would complement our current products, expand the breadth of
our markets, enhance our technical capabilities, help secure critical sources of
supply and the availability of compatible switches or that may otherwise offer
growth opportunities. While we have no current agreements or negotiations
underway, we may buy businesses, products or technologies in the future. In the
event of any future purchases, we could:


     - issue stock that would dilute our current stockholders' percentage
       ownership;

     - incur debt; or

     - assume liabilities.

These purchases also involve numerous risks, including:

     - problems combining the purchased operations, technologies or products;

     - unanticipated costs;

     - diversion of management's attention from our core business;

     - adverse effects on existing business relationships with suppliers and
       customers;

     - risks associated with entering markets in which we have no or limited
       prior experience; and

     - potential loss of key employees of purchased organizations.


     WE MAY NOT BE ABLE TO OBTAIN ADDITIONAL CAPITAL TO FUND OUR OPERATIONS ON
REASONABLE TERMS AND THIS COULD HURT OUR BUSINESS AND NEGATIVELY IMPACT OUR
STOCKHOLDERS.  If adequate funds are not available or are not available on
reasonable terms, we may be unable to develop or enhance our products, take
advantage of future opportunities or respond to competitive pressures, which
could seriously harm our


                                       10
<PAGE>   16


business. If our capital requirements vary from those currently planned, we may
require additional financing sooner than anticipated. If we raise additional
funds through the issuance of debt or equity securities, the percentage
ownership of our existing stockholders may be reduced, the securities issued may
have rights, preferences and privileges senior to those of holders of our common
stock, and the terms of the securities may impose restrictions on our
operations.



     OUR INDUSTRY IS SUBJECT TO EXTENSIVE GOVERNMENT REGULATION THAT COULD CAUSE
SIGNIFICANT DELAYS AND EXPENSE.  Wireless telecommunications are subject to
extensive regulation by the U.S. and foreign governments. If we fail to conform
our products to regulatory requirements or experience any delays in obtaining
regulatory approvals, we could lose sales. Moreover, we only plan to qualify our
products in a foreign country once we have a purchase order from a customer
located there, and this practice may deter customers or contribute to delays in
receiving or filling orders. To date we have not qualified our products in any
foreign countries.



     Continuing regulatory compliance could be expensive and may require
time-consuming and costly modifications of our products. Any failure of domestic
and international regulatory authorities to allocate suitable frequency spectrum
could limit our growth opportunities and our future revenues.


     BECAUSE OUR PRODUCTS ARE HIGHLY COMPLEX AND ARE DEPLOYED IN COMPLEX
NETWORKS, THEY MAY HAVE ERRORS OR DEFECTS THAT WE FIND ONLY AFTER DEPLOYMENT,
WHICH IF NOT REMEDIED COULD HARM OUR BUSINESS.  Our products are highly complex,
are designed to be deployed in complex networks and may contain undetected
defects, errors or failures. Although our products are tested during
manufacturing and prior to deployment, they can only be fully tested when
deployed in commercial networks. Consequently, our customers may discover errors
after the products have been deployed. The occurrence of any defects, errors or
failures could result in installation delays, product returns, diversion of our
resources, increased service and warranty costs, legal actions by our customers,
increased insurance costs and other losses to us or to our customers or end
users. Any of these occurrences could also result in the loss of or delay in
market acceptance of our products, which would harm our business and adversely
affect our operating results and financial condition. We will likely have
limited experience with any problems that may arise with new products that we
introduce.


     IF WE OR OUR KEY SUPPLIERS OR CUSTOMERS FAIL TO BE YEAR 2000 COMPLIANT, WE
MAY INCUR SIGNIFICANT UNEXPECTED EXPENSES, EXPERIENCE BUSINESS INTERRUPTIONS AND
DELAYS, LOSE EXISTING OR POTENTIAL CUSTOMERS AND ORDERS AND EXPERIENCE OTHER
CONSEQUENCES THAT ARE HARMFUL TO OUR BUSINESS.  If our systems or the systems of
our customers or suppliers do not correctly recognize date information when the
year changes to 2000, it could have an adverse effect on our business. The risk
exists primarily in six areas:


     - warranty or other claims from our customers, which may result in
       significant expense to us;

     - failure of systems we use to run our business, which could interrupt our
       business operations;

     - failure of systems used by our suppliers or vendors, which could delay
       manufacturing, affect the quality of our products or delay deployment of
       our products;

     - failure of our products due to year 2000 problems associated with
       components supplied by others for use in our products, which may require
       that we find replacement components or alternative sources and that we
       potentially incur significant unexpected expenses;

     - failure of systems our customers or potential customers use to run their
       businesses, which could affect their ability to purchase products from
       us; and

     - failure of our customers' wireless networks which could affect their
       business and buildout plans.


     If our implementation of upgrades or replacement of noncompliant systems is
delayed, if we fail to identify a non-compliant product or system in a timely
fashion, or if we identify significant non-compliance issues, our business
operations could be interrupted, we could face significant unanticipated
expenses, our management's time and attention could be diverted and our sales
could decline materially. Customers may defer purchases of our products until
the general uncertainty associated with year 2000 has passed.

     OUR STOCK PRICE MAY BE VOLATILE, AND YOU MAY BE UNABLE TO RESELL YOUR
SHARES AT OR ABOVE THE OFFERING PRICE.  There previously has been no public
market for our common stock. We cannot predict the extent to which investor
interest in us will lead to the development of a liquid trading market. The
initial public offering price for the shares 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 market price of our
common stock could be subject to wide fluctuations in response to many risk
factors listed in this section.



     In recent years the stock market has experienced significant price and
volume fluctuations. Our common stock may also experience that volatility
unrelated to our own operating performance for reasons which include:



     - performance of similar companies;



     - news announcements and other developments with respect to our industry or
       our competitors; and



     - changes in general economic conditions.



     A NUMBER OF SHARES ARE OR WILL BE ELIGIBLE FOR FUTURE SALE WHICH MAY
DEPRESS OUR STOCK PRICE.  Sales of substantial amounts of our common stock in
the public market following this offering, or the perception that a large number
of shares are available for sale, could cause the market price of our common
stock to decline. After this offering, shares owned by our current stockholders
and holders of options and warrants to acquire our common stock, on a fully
diluted basis assuming exercise of all options and warrants, including our
executive officers and directors, are expected to constitute approximately
87.37% of the outstanding shares of our common stock, or 84.24% if the
underwriters' over-allotment option is exercised in full. Following the
expiration of a 180-day "lock-up" period to which substantially all of the
shares held by our current stockholders will be subject, the holders whose
shares are subject to that lock-up period will in general be entitled to dispose
of their shares. Moreover, Salomon Smith Barney Inc. may, in its sole discretion
and at any time without notice, release all or any portion of the securities
subject to the lock-up agreements. In addition to the adverse effect a price
decline could have on holders of our common stock, that decline would likely
impede our ability to raise capital through the issuance of additional shares of
our common stock or other equity securities.



     After this offering, the holders of approximately 17,123,441 shares of our
common stock (including shares issuable upon the exercise of outstanding
warrants) will have rights, subject to some conditions, to require us to file
registration statements covering their shares, or to include their shares in
registration statements that we may file for ourselves or other stockholders. By
exercising their registration rights and selling a large number of shares, these
holders could cause the price of our common stock to decline. Furthermore, if we
were to include in a company-initiated registration statement shares held by
those holders pursuant to the exercise of their registration rights, those sales
could impair our ability to raise needed capital by depressing the price at
which we could sell our common stock.



     YOU WILL INCUR IMMEDIATE AND SUBSTANTIAL DILUTION OF THE BOOK VALUE OF OUR
COMMON STOCK THAT YOU PURCHASE IN THIS OFFERING.  The initial public offering
price of our common stock is substantially more than the net tangible book value
per share of our common stock. As a result, holders who purchase our common
stock pursuant to this offering will experience immediate and substantial
dilution in the net tangible book value per share of our common stock from the
initial public offering price. The net tangible book value dilution to new
investors in this offering will be $7.79 per share at an assumed initial public
offering price of $12.00 per share. The exercise of outstanding options and
warrants is likely to result in further dilution to you.



     OUR CERTIFICATE OF INCORPORATION AND BYLAWS, AS WELL AS PROVISIONS OF
DELAWARE LAW, COULD DISCOURAGE POTENTIAL ACQUISITIONS OF OUR COMPANY THAT
STOCKHOLDERS MAY CONSIDER FAVORABLE.  Some provisions of our certificate of
incorporation, our bylaws and Delaware law may discourage, delay or prevent a
merger or acquisition that stockholders may consider favorable. This may reduce
the market price of our common stock.


                                       12
<PAGE>   18


     CONTROL BY OUR EXISTING STOCKHOLDERS WILL LIMIT YOUR ABILITY TO INFLUENCE
THE OUTCOME OF MATTERS REQUIRING STOCKHOLDER APPROVAL AND COULD DISCOURAGE
POTENTIAL ACQUISITIONS OF OUR COMPANY BY THIRD PARTIES. We anticipate that our
executive officers, directors and entities affiliated with them, along with the
current holders of more than 5% of our equity, will, in the aggregate,
beneficially own approximately 56.6% of our outstanding common stock following
the completion of this offering. These stockholders, if acting together, would
be able to influence significantly all matters requiring approval by our
stockholders, including the election of our board of directors and the approval
of mergers or other business combination transactions. This concentration of
ownership could have the effect of delaying or preventing a change in our
control or otherwise discourage a potential acquirer from attempting to obtain
control of us, which in turn could have an adverse effect on the market price of
our common stock or prevent our stockholders from realizing a premium over the
market price for their shares of our common stock.

                                    DILUTION


     The pro forma net tangible book value per share of our common stock is the
difference between our tangible assets and our liabilities, divided by the
number of shares of our common stock outstanding after giving effect to the
automatic conversion of all outstanding shares of preferred stock into shares of
our common stock upon completion of this offering. For investors in our common
stock, dilution is the per share difference between the $12.00 per share assumed
initial offering price of our common stock in this offering and the pro forma
net tangible book value of our common stock immediately after completing this
offering. Dilution in this case results from the fact that the per share
offering price of our common stock is substantially in excess of the per share
price paid by some of our current stockholders for our presently outstanding
stock.



     As of September 30, 1999, without taking into account any changes in our
net tangible book value subsequent to that date other than to give effect to the
sale of our common stock in this offering at the assumed offering price of
$12.00, less the estimated offering expenses including underwriting discounts
and commissions, the pro forma net tangible book value of each of the assumed
outstanding shares of common stock would have been $4.21 per share after this
offering ($93,587,899 pro forma net tangible book value divided by 22,223,736
shares of our common stock). Therefore, investors in our common stock would have
paid $12.00 for a share of common stock having a pro forma net tangible book
value of approximately $4.21 per share after this offering. That is, their
investment would have been diluted by approximately $7.79 per share. At the same
time, our current stockholders would have realized an increase in pro forma net
tangible book value of $2.21 per share after this offering without further cost
or risk to themselves. The following table illustrates this per share dilution:

     The foregoing discussion and tables assume no exercise of any stock options
or warrants outstanding. As of October 26, 1999, there were options outstanding
to purchase a total of approximately 2,006,145 shares of common stock with a
weighted average exercise price of $2.655 per share and warrants outstanding to
purchase a total of 687,492 shares of common stock with a weighted average
exercise price of $3.319 per share. To the extent that any of these options or
warrants are exercised, your investment will be further diluted. In addition,
more options may be granted in the future under our 1999 Equity Incentive Plan.

                                USE OF PROCEEDS


     Our net proceeds from this offering, based on an assumed initial public
offering price of $12.00 per share, are estimated to be $60.1 million, or $69.3
million if the underwriters' over-allotment option is exercised in full, after
deducting underwriting discounts and estimated offering expenses.



     We intend to use the net proceeds of this offering primarily for general
corporate purposes, including working capital, expansion of our engineering
organization, product development programs, sales and marketing capabilities,
and general and administrative functions and capital expenditures. We may also
use a portion of the net proceeds to invest in complementary products, to
license other technology or to make potential acquisitions. However, we have no
current understandings or agreements relating to potential acquisitions and are
not currently engaged in any negotiations with respect to any such transactions.



     The use of proceeds has not been specifically identified due to the
flexible nature of our planning process. The amounts we actually expend for
general corporate purposes will vary significantly depending on a number of
factors, including revenue growth, if any, and the amount of cash we generate
from operations. As a result, we will retain broad discretion in the allocation
and use of the net proceeds of this offering. Pending the uses described above,
we intend to invest the net proceeds from this offering in short-term,
investment grade, interest bearing, securities.


                                DIVIDEND POLICY

     We have never paid dividends on our common stock, and we do not expect to
pay any dividends on our common stock for the foreseeable future. Any future
determination to pay dividends will be at the discretion of our board of
directors and will depend on our financial condition, results of operations,
capital requirements and other factors the board of directors deems relevant.

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


     You should read the following discussion and analysis in conjunction with
"Selected Financial Data" and our financial statements and notes included
elsewhere in this prospectus.


OVERVIEW


     We provide cellular base stations and other wireless telecommunications
infrastructure products designed to support the GSM, or Global Standard for
Mobile Communications, system of mobile voice and data transmission. We market
our products to operators of cellular and other wireless networks. A base
station is a key component of a wireless network and is used to receive and
transmit voice and data signals over radio frequencies. Our products include the
AdaptaCell, a software-defined base station, meaning it uses software to control
the way it encodes and decodes wireless signals, and the AirSite, a backhaul
free base station, meaning it carries voice and data signals back to the
wireline network without using a physical communications link.



     We began marketing our GSM base stations in the beginning of 1996 and
shipped our first GSM base station in May 1997. Through September 30, 1999, we
have shipped and billed for 240 base stations and have five commercially
deployed systems. We currently sell and market our products in the U.S. through
our direct sales force. We are beginning to conduct our international sales and
marketing efforts through a network of agents, distributors and our direct sales
force.



     From our inception in January 1994 through May 1997, our operations
consisted principally of start-up activity associated with the design,
development, and marketing of our products. As a result, we did not generate
significant revenues until 1998 and have generated only $19.7 million in net
revenues through September 30, 1999. We have incurred substantial losses since
commencing operations, and as of September 30, 1999, we had an accumulated
deficit of $95.1 million. We have not achieved profitability on a quarterly or
annual basis. Because we will need to continue to focus heavily on developing
our technology and products, organizing our sales and distribution systems and
assembling the personnel necessary to support our anticipated growth in the near
future, we expect to continue to incur net losses for at least the next several
quarters. We will need to generate significantly higher revenues in order to
support expected increases in research and development, sales and marketing and
general and administrative expenses, and to achieve and maintain profitability.



     Our revenues are derived from sales of a single product line based on the
GSM system. We generate a substantial portion of our revenues from a limited
number of customers, with two customers accounting for 76% of our net revenues
during the nine months ended September 30, 1999. Most of our existing and
potential customers are start-up operators that have not yet commenced the
buildout of their networks, obtained necessary financing or acquired a high
degree of familiarity with our products.


     We have and expect to continue to experience significant fluctuations in
our quarterly revenues as a result of our long and variable sales cycle.
Historically, our sales cycle, which is the period from the time a sales lead is
generated until the recognition of revenue, has ranged from 12 to 18 months. The
length and variability of our sales cycle is influenced by a number of factors
beyond our control, including: our customers' buildout and deployment schedules;
our customers' access to product purchase financing; our customers' degree of
familiarity with our products; the need for functional demonstrations and field
trials; the manufacturing lead time for our products; delays in final acceptance
of products following shipments; regulatory developments; and our revenue
recognition policies. The effect of our long sales cycle on our results is
compounded by our current dependency on a small number of customers.


     Revenue from product sales is recognized after delivery and resolution of
any uncertainties regarding satisfaction of all significant terms and conditions
of the customer contract, which include completion of installation and customer
acceptance of product technical performance. Given our limited operating
history, such uncertainties have been considered resolved to date when the
customer has placed the products in service or completed specified testing
procedures. A number of different factors outside our


                                       20
<PAGE>   26


control can delay satisfaction of these conditions. Since our products are
typically deployed as part of a complete wireless system and we often fulfill
orders through multiple shipments, customers must have received the final
shipment in order to either place our products in service or complete the
specified testing procedures. As of September 24, 1999, the time period between
shipment and revenue recognition has averaged approximately 100 days, has varied
widely, and in one case was as long as 225 days.


     In general, our gross margins will be affected by the following factors:

     - demand for our products and services;

     - new product introductions, both by us and our competitors;

     - changes in our pricing policies and those of our competitors;

     - the mix of base stations and other products sold;

     - the mix of sales channels through which our products are sold;

     - the mix of domestic and international sales; and

     - the volume pricing we are able to attain from contract manufacturers and
       third party vendors.

     We currently obtain all of our primary components and subassemblies for our
products from a limited number of independent contract manufacturers and
purchase circuit boards, electronic and mechanical parts and other component
assemblies from a limited number of OEMs, or original equipment manufacturers,
and other selected vendors. Accordingly, a significant portion of our cost of
revenues consists of payments to these suppliers. The remainder of our cost of
revenues is related to our in-house manufacturing operations, which consist
primarily of quality control, final assembly, testing and product integration.


     Research and development expenses consist primarily of expenses incurred in
the design, development and support of our proprietary technology. We expect
research and development expenses to increase as we continue to develop our
technology and future products. In particular, we may incur significant costs in
connection with our efforts to develop the software needed to upgrade our base
stations to support emerging wireless high-speed data transmission standards.


     Sales and marketing expenses consist primarily of salaries, commissions,
consulting fees, tradeshow expenses, advertising, marketing expenses and
allocated overhead. We intend to increase expenditures for selling and marketing
as a result of expansion of distribution channels, strategic relationships,
sales and marketing personnel, and marketing programs. In particular, there may
be significant costs associated with our efforts to sell our products to larger
U.S. operators and to international operators.

     General and administrative expenses consist primarily of expenses for
finance, office operations, administrative and general management activities,
including legal, accounting and other professional fees and bad debts. Increases
in general and administrative expenses are planned as we expand executive
management, finance and administration support, information systems and other
administrative functions required to support operations and the costs associated
with being a publicly-held company.


  NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1998



     Net revenues:  Net revenues increased $8.7 million or 354% from $2.4
million for the nine months ended September 30, 1998 to $11.1 million for the
nine months ended September 30, 1999. For the nine months ended September 30,
1999, two customers accounted for 77% of our net revenues. One was a new
customer making an initial deployment of infrastructure for its network.



     Gross profit:  Gross profit increased $3.3 million or 488% for the nine
months ended September 30, 1998 to $4.0 million for the nine months ended
September 30, 1999. This increase was due primarily to the increase in revenues
for the same period. The gross profit margin improved to 36% for the nine months
ended September 30, 1999 from 28% for the nine months ended September 30, 1998.


                                       21
<PAGE>   27


     Research and development:  Research and development expenses increased $2.0
million or 23% from $8.6 million for the nine months ended September 30, 1998 to
$10.6 million for the nine months ended September 30, 1999. This increase was
primarily due to new hires and additional purchases of engineering supplies in
support of our continued effort to enhance current products and develop new
products.



     Sales and marketing:  Sales and marketing expenses increased $1.1 million
or 69% from $1.6 million for the nine months ended September 30, 1998 to $2.7
million for the nine months ended September 30, 1999. This increase was
primarily attributable to additional sales and marketing personnel we hired to
expand our sales and distribution networks.



     General and administrative:  General and administrative expenses remained
the same for the nine months ended September 30, 1998 compared to the nine
months ended September 30, 1999.


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


     Net revenues:  Net revenues increased $2.9 million or 178% from $1.6
million for the year ended December 31, 1997 to $4.5 million for the year ended
December 31, 1998. This increase resulted from a full year of shipments of our
GSM base station, which we first deployed in May 1997. Net revenues were
adversely affected in the second and third quarters of 1998 by proceedings of
the United States Federal Communications Commission, or FCC, related to the
final settlement of the auction process for a particular range of wireless
broadcast licenses, which occurred in mid-1998. Many of the start-up operators
who comprise our initial target market postponed their buildouts and new product
purchases during the pendency of these proceedings.



     Gross profit:  Gross profit increased $1.0 million or 152% from $0.6
million for the year ended December 31, 1997 to $1.6 million for the year ended
December 31, 1998. This increase was due primarily to the increase in net
revenues. The gross profit margin was 39% for the year ended December 31, 1997
and 36% for the year ended December 31, 1998. This decrease in gross profit
margin was attributable to unabsorbed overhead costs as we began to expand our
manufacturing capabilities in 1998.


     Research and development:  Research and development expenses increased $1.4
million or 12% from $11.7 million for the year ended December 31, 1997 to $13.1
million for the year ended December 31, 1998. This increase was associated with
new hires and purchases of certain engineering supplies.

     Sales and marketing:  Sales and marketing expenses increased $1.6 million
or 145% from $1.1 million for the year ended December 31, 1997 to $2.7 million
for the year ended December 31, 1998. Expenses increased for the recruitment and
support of additional sales staff to help establish our sales and distribution
activities. Additionally, expenses for travel, trade shows and outside services
contributed to the increase.

     General and administrative:  General and administrative expenses decreased
$1.2 million or 25% from $5.0 million for the year ended December 31, 1997 to
$3.8 million for the year ended December 31, 1998. This decrease was due to a
substantial reduction in all areas of general administrative expense as we sized
operations to more closely match net revenues. This decrease was partially
offset by a $1.5 million provision for bad debts related primarily to one
customer.

  YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

     Net revenues:  Net revenues increased $0.5 million or 49% from $1.1 million
for the year ended December 31, 1996 to $1.6 million for the year ended December
31, 1997. This increase was due to our first deployment of digital GSM base
stations in 1997.

                                       22
<PAGE>   28


     Gross profit:  Gross profit increased $0.2 million or 53% from $0.4 million
for the year ended December 31, 1996 to $0.6 million for the year ended December
31, 1997. This increase was due primarily to the increase in net revenues offset
by a writedown of $5.6 million for obsolete analog inventory. The gross profit
margin was 38% for the year ended December 31, 1996 and 39% for the year ended
December 31, 1997.



     Research and development:  Research and development expenses decreased $9.2
million or 44% from $20.9 million for the year ended December 31, 1996 to $11.7
million for the year ended December 31, 1997. This decrease resulted from the
completion in 1996 of the modification of our product platform to support
digital instead of analog wireless standards and for which we incurred a higher
level of expenditures in 1996.


     Sales and marketing:  Sales and marketing expenses decreased $1.1 million
or 49.0% from $2.2 million for the year ended December 31, 1996 to $1.1 million
for the year ended December 31, 1997. This decrease resulted primarily from
reduced publications and trade show and travel expenditures.


     General and administrative:  General and administrative expenses decreased
$1.3 million or 21% from $6.3 million for the year ended December 31, 1996 to
$5.0 million on for the year ended December 31, 1997. This decrease was the
result of reductions in headcount and recruitment expense, expensed equipment,
and consulting/legal fees.



     Loss on disposal or write-down of equipment:  As a result of discontinued
development efforts related to our analog base station, we incurred expenses of
$1.1 million for the year ended December 31, 1996 primarily for the loss on the
disposal or write-down of analog-based equipment.


     Other income (expense), net:  Other income of $0.8 million for the year
ended December 31, 1996, resulted from interest income generated from the
Company's cash balances during the year.

     We have experienced and expect to continue to experience significant
fluctuations in quarterly operating results as a result of many factors. We
believe that period-to-period comparisons of our operating results are not
meaningful and should not be relied upon as any indication of future
performance. It is likely that future quarterly operating results from time to
time will not meet the expectations of market analysts or investors, which may
have an adverse effect on the price of our common stock.

LIQUIDITY AND CAPITAL RESOURCES


     Since our inception, we have financed our operations primarily through the
private sales of equity securities, which have provided aggregate net proceeds
of approximately $130 million through September 30, 1999, including the net
proceeds from our offering of Series G preferred stock. At September 30, 1999,
we had approximately $27.0 million in cash. We have no credit facilities.



     Net cash used in operating activities was approximately $25.2 million in
1996, $17.9 million in 1997, $17.8 million in 1998 and $9.6 million in the nine
months ended September 30, 1999. The significant use of cash by operating
activities was the result of the net losses during all reported periods together
with cash used to finance our increase in accounts receivable and inventory
purchases. Customers are billed as contractual milestones are met. Deposits of
up to 50% of the contracted amount are received at the inception of the contract
and an additional amount which, together with the deposit, may range from 50% to
90% of the contracted amount, is billed upon shipment. However, while most of
the remaining unbilled amounts are invoiced after satisfaction of all
significant terms and conditions of the customer contract, collection of the
entire amounts due under our contracts to date have lagged behind shipment of
our products due to the substantial time period between shipment and customer
acknowledgement of the fulfillment of all of our applicable post-shipment
contractual obligations, the time at which we bill the remaining balance of the
contracted amount. This lag requires increasing investments in working capital
as our revenues increase. As of September 30, 1999, our receivables balance was
$6.8 million. This balance is primarily attributable to two customers, and
receivables from one of these customers accounted for approximately 61% of the
total amount outstanding.



     We used net cash for capital expenditures of approximately $2.4 million,
$1.3 million, $0.9 million and $0.6 million for the periods ended December 31,
1996, December 31, 1997, December 31, 1998 and September 30, 1999, respectively.
These expenditures reflect our investments in computer equipment, software
development tools and test equipment, which was required to support our business
expansion.



     We anticipate an increase in our capital expenditures for testing and
manufacturing equipment used during the final assembly of our product as our
revenues increase. Through December 31, 1999, we estimate that capital
expenditures will total approximately $1.5 million.



     We lease our primary manufacturing and office facilities under long-term
non-cancelable operating leases. We also have operating leases for certain other
furniture, equipment and computers. We used net cash for operating leases of
approximately $1.5 million, $1.4 million, $1.1 million, and $0.7 million for the
periods ended December 31, 1996, December 31, 1997, December 31, 1998 and
September 30, 1999, respectively. Future minimum lease payments aggregated
through the year 2003 are approximately $1.5 million as of September 30, 1999.



     We also lease certain computer and test equipment under capital lease
arrangements. We used net cash for capital leases of approximately $0.4 million,
$0.4 million, $0.6 million, and $0.6 million for the periods ended December 31,
1996, December 31, 1997, December 31, 1998 and September 30, 1999, respectively.
Future minimum lease payments aggregated through the year 2003 are approximately
$0.7 million as of September 30, 1999.



     We believe that our available cash resources combined with the net proceeds
of this offering will be sufficient to fund operating losses and meet our
presently anticipated working capital and capital expenditure requirements for
the next twelve months. Thereafter, we may need to raise additional funds. We
may need to raise additional funds sooner to fund more rapid expansion, continue
development of new or enhanced products, respond to competitive pressures, fund
unexpected expenditures or operating losses or acquire businesses or
technologies. If additional funds are raised through the issuance of equity
securities, the percentage ownership of our stockholders will be reduced,
stockholders may experience additional dilution, or such equity securities may
have rights, preferences or privileges senior to those of the holders of our
common stock. If we raise additional funds through the issuance of debt
securities, those securities would have rights, preferences and privileges
senior to those of holders of our common


                                       25
<PAGE>   31


stock, and the terms of this debt could impose restrictions on our operations.
Additional financing may not be available when needed, on favorable terms or at
all.


YEAR 2000 COMPLIANCE

     Many existing computer programs and systems use only two digits to identify
a year in the date field. For example, "99" would represent 1999. These programs
and systems were designed and developed without considering the impact of the
upcoming millennium. Consequently, date sensitive computer programs may
interpret the date "00" as 1900 rather than 2000. If not corrected, many
computer systems could fail or create erroneous results in 2000.


     State of Readiness.  We have completed an assessment of all of our internal
and external systems and our products with respect to the year 2000 issue. In
response to this assessment, we created a year 2000 committee to resolve any
non-compliant year 2000 systems and issues. We plan to complete testing all of
our internal and external systems, including the associated year 2000 fixes for
year 2000 compliance by December 15, 1999. As part of our process, we have
assessed the potential impact of year 2000 failures from vendors and other
companies upon our business and we are currently taking steps to minimize this
risk. We are in the final stages of assessing and verifying the year 2000
compliance of all of our suppliers and vendors. Verification will be
accomplished through the use of written inquiries to suppliers, certifications,
audits and information provided by suppliers on their websites. Some vendors
have not yet responded to our inquiries regarding year 2000 compliance. Based on
our current state of readiness, the actions we are currently taking and the
responses received from our suppliers and vendors to date, we do not believe
that the year 2000 problem will have a material adverse effect on our financial
position, liquidity, or operations.


     Our Costs of Year 2000 Compliance.  We estimate that our total costs of
year 2000 compliance will be less than $100,000. These costs include updating
our computer software and hardware, as well as contracting outside experts and
out-of-pocket expenses.

     Risks of Year 2000 Issues.  We procure crucial components used in our
manufacturing process from foreign vendors. As a result, we may be at risk from
foreign companies and countries that are not taking adequate measures to ensure
year 2000 compliance or that may not be at the same level of preparedness as
companies in the United States. For example, economic problems in Asia may
affect or divert resources with respect to the year 2000 issue. The failure of
those foreign countries and companies to be year 2000 compliant may cause
material shortages that could adversely impact our manufacturing operations. In
addition, some of our customers may experience catastrophic year 2000 failures,
including prolonged interruptions in their business, in which case they may have
a reduced demand for our products.


     We may not be able to upgrade any or all of our major systems in accordance
with our plan to address the year 2000 issue. In addition, any such upgrades may
not effectively address the year 2000 issue. If required upgrades are not
completed or are unsuccessful, our operations may be materially adversely
affected. Furthermore, systems of other companies on which our own systems rely
may not be timely converted. A failure to convert by another company or a
conversion that is incompatible with our system could result in the:


     - failure of our products due to year 2000 problems associated with
       components supplied by others for use in our products, which may require
       that we find replacement components or alternative sources and that we
       potentially incur significant unexpected expenses;

     - failure of systems our customers or potential customers use to run their
       businesses, which could affect their ability to purchase products from
       us; and

     - failure of our customers' wireless networks which could affect their
       business and buildout plans.

     Any failures by our suppliers or vendors to ensure the year 2000 compliance
of their operations and the products and services they provide us could also
seriously harm our business. In addition, customers may defer purchases of our
products until the general uncertainty associated with year 2000 has passed.

                                       26
<PAGE>   32

We cannot anticipate all customer situations and we may see an increase in
warranty and other claims as a result of the year 2000 transition.


     Our Contingency Plans.  We are developing contingency plans with respect to
significant year 2000 issues that are within our control. We intend to replace
any suppliers or vendors who are found not be 2000 compliant with vendors that
are 2000 compliant. However, we plan to continue utilizing only one or a small
number of suppliers for each of the components of our base station systems.
Therefore, replacing a supplier may be disruptive to our business and result in
the loss of sales. In addition, even if we believe a supplier or vendor to be
year 2000 compliant, that supplier or vendor may still have year 2000 problems.
We believe that, apart from the loss of important suppliers and vendors, the
worst case year 2000 scenario would involve disruption of our utilities and
banking facilities.

                                    BUSINESS

OVERVIEW


     We provide cellular base stations and other wireless telecommunications
infrastructure products designed to support the GSM, or Global Standard for
Mobile Communications, system of mobile voice and data transmission. We market
our products to operators of cellular and other wireless networks. A base
station is a key component of a wireless network that receives and transmits
voice and data signals over radio frequencies. We designed our base stations to
be easier to deploy and upgrade and to have lower capital and operating costs
than other existing base stations. Our system features two innovative base
station products:



     The AdaptaCell is a software-defined base station, meaning it uses software
to control the way it encodes or decodes wireless signals. Our AdaptaCell
incorporates a proprietary radio architecture that is designed to enable
operators to upgrade their wireless networks to offer high-speed data and
Internet services by changing software rather than deploying new base stations.
Our AdaptaCell also incorporates a broadband architecture, meaning that it uses
only one radio to process a large number of radio channels.



     The AirSite is a backhaul free base station, meaning it carries voice and
data signals back to the wireline network without using a physical
communications link. Our AirSite uses an operator's existing radio frequencies
as the medium to provide the necessary connection to the wireline network.
Unlike our competitors' base stations, our AirSite does not require an expensive
physical communications link, usually through a digital T-1 phone line, to the
wireline network. As a result, an operator's fixed network operating costs may
significantly decrease.



     We were founded in 1994 and have raised approximately $130 million from
inception through September 30, 1999 to develop our technology and fund
operations. We have 33 domestic patents granted, 22 patent applications pending,
and 2 provisional patent applications. We received the 1998 GSM World Award for
Best Technical Innovation from the GSM Association, an international body with
members from 133 countries, in recognition of our revolutionary infrastructure.


INDUSTRY BACKGROUND


     In recent years, there has been substantial growth in the number of
wireless users around the world, reaching 303 million subscribers in 1998
according to International Data Corporation, or IDC. IDC estimates that the
number of wireless users will reach approximately 1.1 billion in 2003,
representing a compound annual growth rate of 29%. We expect the following
factors to contribute to continued growth in wireless usage:


          Improved Coverage.  Due to the high start-up costs involved, initial
     wireless deployments were limited to urban centers and major traffic
     corridors. Existing operators have accelerated the buildout of their
     networks to meet demands for improved service, including seamless roaming
     across local, regional and even national markets. In addition, new
     operators have sought to develop their own networks in locations where
     service had previously been inadequate or too costly.

          Lower Price.  The price of wireless services has decreased
     significantly in developed markets. With as many as six wireless service
     operators in some U.S. markets, operators are seeking to enhance their
     competitive position with more efficient and cost effective networks.


          New Wireless Services.  Wireless networks have traditionally been
     designed to support voice traffic. With the advent of the Internet and
     increased focus on the development of high capacity wireless networks, we
     expect operators to make additional infrastructure investments in order to
     offer high-speed data and Internet services while seeking to ensure
     compatibility with their existing networks.


                                       28

     There has also been a substantial increase in wireless minutes of use.
According to Paul Kagan Associates, Inc., wireless minutes of use in the U.S.
are expected to increase from approximately 64 billion in 1997 to an estimated
150 billion in 1999. Subscribers are beginning to use wireless telephones as a
substitute for wireline communications. Operators are striving to keep up with
the resulting demand by adding more base stations and increasing the capacity of
existing base stations to increase the number of channels in their networks.
Compounding the challenge, new service providers operating at higher frequencies
can require up to four times as many base stations as traditional wireless
networks in order to achieve the same coverage pattern. As a result, Allied
Business Intelligence, Inc. predicts there will be approximately 2.3 million
wireless base stations deployed by 2003 compared to approximately 823,000 in
1998, representing a 23% compound annual growth rate.



     Various analog and digital standards for wireless voice and data
transmission are currently available to wireless service operators, including:
Global Systems for Mobile Communications, known as GSM; Code Division Multiple
Access, known as CDMA; and Time Division Multiple Access, known as TDMA. Unlike
CDMA and TDMA, GSM incorporates an open interface between the base station and
mobile switching center. This open interface makes it easier for wireless
service operators to purchase and integrate GSM system elements, including base
stations, from multiple vendors rather than relying on a single vendor. Although
GSM is based on a number of well-defined standard interfaces, a GSM mobile
telephone switch may be manufactured according to different variations within
the standard interface. As a result, we may encounter obstacles when we attempt
to integrate our products with a particular switch, since we have not yet tested
our products for compatibility with several vendors' switches. If our products
are not initially compatible with a particular mobile telephone switch, we can
make modifications to account for such variations in the standard interface. To
date, we have had little difficulty interfacing our system with multiple
vendors' switches.



     GSM is the most widely used wireless standard worldwide, with systems
operating in approximately 120 countries and serving over 160 million
subscribers as of April 1999. This represents 45% of all wireless subscribers
and 65% of digital wireless subscribers worldwide. As of September 1999, the
number of subscribers using this standard increased to approximately 200
million.



     In the U.S., TDMA and CDMA are currently the most widely used standards.
According to Allied Business, Inc. in 1998, there were approximately 8.1 million
TDMA subscribers and approximately 5.8 million CDMA subscribers. The primary
users of these standards in the U.S. have been the traditional large wireless
operators. According to Allied Business Intelligence, Inc. at the end of 1998
there were 3.0 million GSM subscribers in the United States, representing 4.3%
of wireless subscribers in the United States.



     The growth in demand for wireless services caused a strain on the capacity
of existing wireless networks. Partially in response, the FCC allocated new
radio frequency spectrum for wireless services through a series of FCC auctions
and re-auctions commencing in late 1994 and ending in early 1999. Many of the
winners in this auction process were smaller, entrepreneurial wireless service
operators. These new operators are faced with the challenge of rapidly deploying
a wireless network infrastructure and establishing a competitive footprint, or
geographic coverage area, in order to interest potential subscribers and become
competitive with established operators. Because of these challenges, we believe
that these new operators are seeking to deploy an infrastructure with the lowest
capital and operating costs possible, while preserving their ability to support
additional subscribers and future high-speed data services. Due to its proven
technology and global roaming capability, many of these new operators have
selected GSM.



     Government bodies in other countries are, like the FCC, auctioning off
radio frequency spectrum. We believe the same dynamics that led new domestic
operators to choose GSM will also lead many new international operators to
select GSM. In addition, the less-developed countries of Asia, Africa, Eastern
Europe, and South America have limited wireline infrastructure, creating new
opportunities for wireless operators. Therefore, we believe there will continue
to be a strong international demand for GSM and the associated infrastructure
equipment.



     Existing GSM base stations were designed to support larger operators
providing voice service in heavily populated areas. As a result, they are not
cost-effective when used in low population density areas.

                                       29
<PAGE>   35


In addition, these base stations cannot be easily upgraded to support high-speed
data and wireless Internet services. A further problem with these base stations
is the cost associated with expensive physical communications links, usually
through a digital T-1 phone line, to connect each base station to the wireline
network. This can result in significant recurring expense for most operators.



     The European Telecommunications Standards Institute, a leading worldwide
promoter of standards for the telecommunications industry, has proposed next
generation standards for GSM that will enable GSM to provide high-speed data and
wireless Internet services. We expect these standards to be introduced in
several phases starting with GPRS, then EDGE, and finally 3G. Industry leaders
have proposed a similar evolution path for TDMA, in which TDMA will converge
with GSM by adopting the EDGE standard for high-speed data and wireless Internet
services.



     A key challenge for wireless service operators will be to incorporate new
high-speed data services into their networks while limiting the amount of new
infrastructure required. Operators may be required to install three different
sets of hardware: one to handle the current GSM standard, one for high-speed
data based on EDGE, and yet another for very high-speed data service based on
3G. In addition to the associated incremental costs, these service overlays
could be inefficient because it may not be possible to move system capacity from
one type of base station to another without adding additional hardware. Finally,
at present, our competitors' base stations cannot be easily modified to
substantially increase capacity to handle the expected increase in voice
traffic. We believe base stations with substantially increased higher capacity
will become crucial as high-speed data is increasingly accepted, occupying a
greater percentage of a wireless service operator's total system capacity and
leaving less capacity for conventional voice traffic.


THE AIRNET SOLUTION


     We believe our software-defined solution positions us to meet the
industry's challenge of transitioning from today's existing GSM networks to
tomorrow's integrated voice and high-speed data networks. The timing of this
transition and the exact specifications of these new standards are uncertain. We
believe that our software-defined solution will be particularly valuable to
operators during this uncertain transition as it enables operators to purchase
infrastructure today which can be adapted to tomorrow's new standards.


     We believe our solution reduces an operator's total cost of owning and
operating wireless networks. Our solution features two innovative base station
products, the AdaptaCell and the AirSite Backhaul Free Base Station, which
provide the following key benefits:


          Adaptable and Easy to Upgrade.  Our AdaptaCell base station
     incorporates a broadband architecture and is software-defined, meaning it
     uses only one radio or transceiver to process a large number of radio
     channels and uses software to control the way it encodes and decodes
     wireless signals. We expect this design will allow operators to support new
     standards such as GPRS and EDGE through only changes in software. To
     support 3G, a few, if any, hardware modifications may be required in
     addition to a software upgrade. By contrast, other existing base stations
     must be extensively modified or even replaced if operators want to offer
     new high-speed data and wireless Internet services to their customers. As
     wireless operators adopt new high-speed data standards like GPRS, EDGE and
     3G, we believe the AdaptaCell's design will position our system as a
     preferred solution. Also, since the AdaptaCell is designed to be configured
     to support more than one standard at the same time, a single base station
     could, for example, be configured to support voice, EDGE and 3G
     simultaneously.



          Lower Operating Costs.  Our base stations are designed to result in
     substantially lower operating costs per subscriber than our competitors'
     base stations. Base stations usually require expensive physical
     communications link, typically a digital T-1 phone line, to connect to the
     wireline network. The AirSite features its own integral wireless backhaul,
     meaning it carries voice and data signals back to the wireline network
     without using a physical communications link. Our AirSite uses an
     operator's existing radio frequencies as the medium to provide the
     necessary connection to the wireline network.


                                       30
<PAGE>   36


     This eliminates the need for a T-1 or any other physical connection from
     the AirSite back to the AdaptaCell. In addition, eliminating coverage holes
     with other existing base stations may not be cost-effective because an
     expensive T-1 or physical link from each base station to the base station
     controller is required. In contrast, our system only requires a T-1 line or
     other physical backhaul connection between the base station controller and
     the AdaptaCell base stations, each of which can service up to 12 separate
     AirSites. Finally, our simplified hardware design results in a smaller base
     station that has fewer components, is easier to install and maintain and
     uses less electricity.



          Flexible Deployment.  As opposed to our competitors' systems, our
     scaleable solution allows operators to start small, establish a network,
     and incrementally expand coverage and capacity as subscriber demand
     increases. In addition, because AirSites are backhaul free, operators are
     able to deploy them in new and innovative ways. For example, some customers
     have mounted AirSites on telephone poles and billboards, reducing the time
     and cost associated with deploying a base station by simplifying zoning and
     tower construction issues.


STRATEGY

     Our goal is to become a leading worldwide supplier of wireless base
stations. Our strategy for achieving this goal includes the following core
elements:


     Leverage Our Technology Leadership.  Since our inception, we have raised
approximately $130 million to develop our technology and fund operations. We
have 33 domestic patents granted, 22 patent applications pending, and 2
provisional patent applications. We believe that we currently have the only
commercially deployed broadband, software-defined base station. The
technological advances incorporated in our base stations provide our customers
with significant advantages. We intend to leverage our technology leadership by
continuing to invest in our substantial research and development efforts in
order to continue to provide our customers with cost-effective, innovative
solutions.



     Continue to Market our Product Advantages to Domestic Operators.  We will
continue to focus on providing infrastructure to domestic wireless service
operators deploying GSM systems in new markets, known as initial-coverage areas,
or filling gaps in existing deployments, known as coverage-limited areas. Many
of these operators are currently engaged in significant initial-coverage and
coverage-limited deployments. We also plan to target the larger domestic GSM
operators as they address buildouts in their own suburban and low-population
density areas. These larger operators are continually upgrading and expanding
coverage to maintain parity with their competitors. Our cost-effective,
scaleable infrastructure is designed to meet the needs of both new and existing
operators.



     Expand Into International Markets.  We believe success in domestic markets
will facilitate entry into international markets. The large infrastructure
vendors have targeted Europe and other high population density areas overseas
and have not focused as much on developing cost-effective products for use in
low population density areas. Using the same strategy we successfully
implemented in the U.S., we are focusing our international marketing efforts on
low population density markets such as Africa, Asia, Eastern Europe and South
America. We recently announced versions of our products modified for
international markets. To achieve an international market presence as quickly as
possible, we are establishing a network of agents, distributors, and OEMs.



     Establish a Market Leadership Position in High-Speed Data Base Station
Markets.  Our AdaptaCell positions us to establish a market leadership position
as wireless communications evolve from voice to high-speed Internet access. The
AdaptaCell is designed to support multiple wireless standards, enabling a single
base station to service voice and high-speed data subscribers simultaneously. We
have also designed the AdaptaCell to serve as the basis for a new generation of
base stations which will have substantially increased capacity.

WIRELESS SYSTEM TECHNOLOGY

                     Figure 1 -- Mobile System Architecture

                        [BASE STATION SUBSYSTEM GRAPHIC]


     Wireless telephone systems operate by dividing a geographic service
territory into a number of regions called cells. As Figure 1 shows, each cell
contains a base station that communicates with the wireless telephones located
in that cell. When a subscriber wishes to place a call, a signal is sent from
the subscriber's telephone to the base station in the cell in which the
subscriber is located. The base station completes the call via the base station
controller and mobile switching center, and then assigns one of several
available channels to be used by the subscriber's telephone while operating
within the cell's range. Since all telephone conversations are inherently
two-way, a similar reverse channel from the base station to the subscriber is
assigned at the same time.



     In conventional analog phone systems, a channel occupies an entire radio
frequency carrier. In digital TDMA and GSM, a channel occupies only a small
fraction, or timeslot, within a particular radio frequency carrier. In these
systems, each wireless telephone waits for its assigned channel timeslot and
broadcasts the subscriber's digitized speech. Thus, multiple callers can make
use of the same radio frequency carrier at the same time. In digital CDMA, the
notion of a channel is more complex because all subscribers make use of the
entire available radio frequency spectrum simultaneously. In these systems, each
subscriber is assigned a unique identification code, which the telephone uses to
mathematically process the subscriber's voice and spread the signal across the
entire radio frequency spectrum. On the receiving end, the receiver uses the
same unique code to unscramble the signal. In analog and digital TDMA and GSM
wireless systems, each telephone is assigned a new channel when it enters a
cell. As a wireless telephone moves from cell to cell, it is transferred to an
adjacent base station and then reassigned a new channel. In digital CDMA
systems, no channel reassignments are necessary because the base station in the
new cell simply starts unscrambling the subscriber's signal and the old cell
stops.



     Our competitors' base stations can only support a single specific standard
and require different hardware to support each standard. These are known as
hardware base stations. In a hardware base station, a discrete set of components
processes each radio frequency carrier. Adding voice channels requires
additional carriers, which typically means adding new hardware. As new
high-speed data standards, such as EDGE and 3G, are developed and deployed, an
operator may need to install new base stations to support these standards
because existing base stations are primarily designed to support only voice
services. An additional complication arises because not every subscriber can be
expected to migrate to the new service when it is first deployed. To accommodate
these late adopters, operators may need to support more than one standard
simultaneously. In these cases, an additional base station may be required.


                                       32
<PAGE>   38


     Our AdaptaCell receives wireless telephone signals from subscribers by
digitizing a full 5 MHz of the wireless service operator's radio frequency
spectrum and then processing the digitized spectrum using a series of digital
signal processors that run our proprietary software. An inverse process occurs
when transmitting to subscribers. When configured to support the GSM standard,
one of our broadband, software-defined radios can process up to 12 GSM radio
frequency carriers supporting 96 independent channels comprised of 92 voice
channels and 4 control channels using a single set of hardware. Base stations
utilizing narrowband radio technology use 12 duplicate sets of hardware in order
to accomplish the same task as one of our AdaptaCell base stations. This is
shown in Figure 2.



       Figure 2 -- Narrowband Radio Technology Versus AirNet's Broadband,

                       Software-Defined Radio Technology

                  [RADIO TECHNOLOGY/AIRNET BROAD BAND GRAPHIC]


     Our AdaptaCell is based on broadband, software-defined radio. We believe we
are the only base station manufacturer to have successfully deployed this
technology in commercial service. The term software-defined means that the way
the radio encodes and decodes signals is controlled by the installed software.
As new standards are developed and deployed, the same radio can be configured to
support multiple standards by loading new software into the radio. To accomplish
this, we believe our competitors' base stations will require significant
hardware changes which may be expensive. The term broadband means that the
AdaptaCell has one radio or transceiver that processes 5 MHz of radio frequency
spectrum on both transmission and reception. By contrast, base stations
utilizing narrowband radio technology use many independent narrowband radios
that individually process a much smaller amount of radio frequency spectrum,
1/25 as much in the case of GSM, which in effect limits them to one standard. As
such, the AdaptaCell has far fewer components than other existing base stations,
a design feature that increases reliability and lowers costs.



     We have designed our broadband, software-defined base stations to support
more than one kind of wireless service on the same base station at the same
time. This is important because as new wireless services such as EDGE and 3G
high-speed data are deployed, many subscribers will still be using wireless
telephones that operate on older standards. These subscribers will expect their
telephones to continue to work as new standards are deployed. Operators using
our competitors' products will have to continually change hardware, or even
deploy multiple base stations that support old and new standards, to serve
different populations of subscribers using wireless telephones. After completion
of a software upgrade and perhaps a few hardware modifications, changing a
setting at a central control point is all that will be required to vary the
level of support given to each standard on an AdaptaCell.

PRODUCTS


     Our base station subsystem products currently support the GSM system for
wireless voice and data communications services. We chose to develop products
based on this standard because the interfaces, or connections, between the
various pieces that make up the GSM base station subsystem are well defined and
publicly documented. One of these interfaces, the connection between the mobile
switching center and the base station controller, and ultimately the base
stations that compose the base station subsystem, is referred to as the
A-interface. This A-interface allows wireless operators to attach our base
station subsystem equipment to an existing operator's mobile switching center.
It is this standard interface that makes any existing GSM operator a potential
customer for our base station subsystem equipment. We are currently marketing
the base station subsystem in three standard configurations, the GSM-900,
GSM-1800 and GSM-1900, operating at 900 MHz, 1800 MHz and 1900 MHz respectively.



     As shown in Figure 3, our base station subsystem features two base
stations: the AdaptaCell broadband, software-defined GSM base station and the
AirSite Backhaul Free Base Station. We also offer custom-tailored ancillary
equipment that completes the base station subsystem. These include a base
station controller, a transcoder rate adaptation unit and an operations and
maintenance center (radio).


                 Figure 3 -- AirNet GSM Base Station Subsystem

                     [AIRNET BASE STATION SUBSYSTEM IMAGE]


     AdaptaCell.  The AdaptaCell wireless base station supports up to 12 GSM
radio frequency carriers (96 total channels including 92 voice/data channels and
four control channels). The AdaptaCell differs from our competitors' base
stations in that its operation is defined by software, not hardware. This means
that as subscribers demand new services from operators, specifically new
high-speed data and Internet services, it will be possible to upgrade the
AdaptaCell to support those services via a change of software and few, if any,
hardware modifications. Operators using our competitors' equipment will likely
have to install new equipment, and potentially a completely new base station,
for each new wireless standard they adopt. The AdaptaCell is available in two
basic configurations: omni-directional and sectorized. An omni-directional base
station serves a roughly circular geographic area while a sectorized base
station divides the area around it into independent sectors. Sectorized base
stations are useful in high-density applications because they allow a wireless
service operator to reuse frequencies in adjacent cells more readily than with
omni-directional base stations. Figure 3 shows an omni-directional
configuration.


                                       34
<PAGE>   40


     AirSite.  The AirSite is a compact wireless base station that supports one
GSM radio frequency carrier (eight total channels including seven voice/data
channels and one control channel) and includes its own wireless backhaul system.
By contrast, other existing base stations must be connected to the rest of the
system using expensive physical communications links, usually digital T-1 lines.
The AirSite is a true GSM base station, meaning it has a unique site ID for
billing and "911" emergency identification purposes, offers the same geographic
coverage as other existing base stations, and has fault and error detection
functionality fully integrated into the operations and maintenance center
(radio). The AirSite operates by receiving a subscriber's wireless telephone
signal and transmitting it to the AdaptaCell. The AdaptaCell then sends the
signal over a T-1 line to the base station controller and on to the mobile
switching center. In reverse, digitized voice signals come from the mobile
switching center to the base station controller and then to the serving
AdaptaCell, which then transmits the signal to the AirSite. The AirSite then
transmits the signal to the subscriber. System capacity can be expanded by
deploying two AirSites in a tandem configuration at the same cell site, thus
supporting two GSM radio frequency carriers (16 total channels including 15
voice/data channels and one control channel).



     Base Station Controller.  Our base station controller coordinates the
activities of the AdaptaCells physically attached to it and all the AirSites
served by those AdaptaCells. A single base station controller can support up to
20 AdaptaCells and up to 240 AirSites. Among other things, the base station
controller monitors handset signal levels and the operational status of each of
its attached base stations, controls handset transmit power, and orchestrates
handoffs between base stations.



     Transcoder Rate Adaptation Unit.  In most telecommunications systems,
digitized voice requires 64 Kbps of bandwidth to accurately convey human speech.
Our transcoder rate adaptation unit compresses a standard 64 Kbps voice stream
to a GSM standardized 13 Kbps format more suitable for transmission within the
base station subsystem. This means that the digital T-1 line used to connect the
base station controller to the mobile switching center can carry four times as
many voice conversations as it normally would. This makes it less expensive to
attach a base station subsystem to its associated mobile switching center.



     Operations and Maintenance Center (Radio).  The operations and maintenance
center-radio provides the network management facility for one or more of our
base station subsystems. Our operations and maintenance center (radio) provides
a comprehensive graphical user interface for maintenance personnel. In its
maximum configuration, one operations and maintenance center (radio) can
simultaneously manage 10 base station controllers, 200 AdaptaCells, and 2,400
AirSites.

SALES AND MARKETING

     We sell and market our products in the U.S. through our direct sales force.
Our international sales and marketing efforts are conducted through a network of
agents, distributors and our direct sales force. We have developed programs to
attract and retain high quality, motivated sales representatives that have the
technical skills and consultative sales experience necessary to sell our
infrastructure solutions.

     We have established a marketing communications organization that is
responsible for the branding and marketing of our products and services and for
distinguishing the AirSite and AdaptaCell as branded product offerings. The
marketing organization is responsible for all new product launches to ensure
both internal execution and marketplace acceptance.

     Direct Sales.  Our direct sales force works as a team with our support
personnel. The direct sales account manager contacts a potential customer and
assists that customer in identifying its technology goals. A budgetary proposal
is then prepared for the customer containing a pro forma business analysis
comparing the customer's initial deployment costs and operating expenses using
traditional wireless infrastructure with those costs and expenses using our
products. The customer is then invited for an executive visit to review our
manufacturing and development facilities in Melbourne and tour one of our
deployed systems, and to discuss the customer's needs for financing, if any.
Final contract negotiations are scheduled shortly thereafter.


     We have initiated direct sales efforts in the United States, Australia,
Africa, South America, and the Pacific Rim.



     International Sales Agents, Distributors and OEMs.  In order to further our
international sales objectives, we are establishing relationships with a number
of country/region specific sales agents, distributors, and OEMs. Our network
currently consists of sales agents working in Africa, Chile and Venezuela and a
distributor working in Australia. Since GSM has been widely adopted throughout
the world, other geographical areas have been targeted for penetration via
similar third party relationships; most notably, Eastern Europe and the Pacific
Rim.

RESEARCH AND PRODUCT DEVELOPMENT


     Our product strategy is to develop and offer a suite of software upgrade
packages designed to run on our AdaptaCell platform to support future high-speed
data standards while augmenting our line of backhaul free base stations with new
lower-cost designs.


     We have invested heavily in the development of broadband, software-defined
base station technology. We began development in 1994 and shipped our first
prototype base stations in 1996.


     In mid-1997, we deployed our first GSM base station subsystem. This system
was placed in commercial service in late 1997 and continues in service.



     In 1998, we focused on adapting the base station subsystem for connection
to other vendor's switching equipment at the industry standard GSM A-interface.
During the year, we shipped products that were successfully integrated with
switches provided by two vendors, including Nortel Networks Corporation. We also
added additional features such as support for short message service and enhanced
full-rate vocoders.



     In 1999, we shipped the AdaptaCell, which is the third generation of our
broadband, software-defined base station. This third generation base station may
be deployed in sectorized configurations. In addition, the AdaptaCell can also
be configured to operate on frequency bands used by GSM operators in
international markets.



     Our current product development plans focus on the GPRS, EDGE and 3G
high-speed data standards. We first plan to develop a GPRS high-speed data
upgrade package. We also plan to take advantage of the evolution of digital
signal processors and other digital components to reduce the cost of our base
stations.



     Subsequently, we expect to develop an EDGE high-speed data upgrade package.



     Ultimately, we expect to develop one or more 3G software upgrade packages.
We may not be able to introduce these or any other products as scheduled. In
addition, market conditions may not ultimately dictate the necessity of
developing upgrade packages to support one or more of these emerging 3G high-
speed data standards. Also, while few modifications to the AdaptaCell hardware
platform are expected as the product evolves, some enhanced hardware, including
upgraded digital signal processors, will be required to support certain
features.



     Our product development strategy has been to concentrate our engineering
resources on our core technology while making maximum use of third party vendors
and products for everything else. In practice, this means our engineering
resources are focused on broadband, software-defined base station technology,
backhaul free base stations, and the software upgrades necessary to support new
high-speed data standards.



     As of September 30, 1999, 97 of our 153 employees were engaged in research
and product development, including hardware and software engineering.


MANUFACTURING

     We currently use a limited number of third-party contractors to manufacture
all of our primary components and subassemblies for our products. As a result,
our in-house manufacturing operations consist primarily of quality control,
final assembly, testing and product integration. Circuit boards, electronic and
mechanical parts, and other component assemblies are purchased from OEM
manufacturers and other selected vendors. Quality control is maintained by an
in-house staff that sets standards and manages our manufacturing contractors.
There is currently only one supplier of high power amplifiers, a critical
component of our broadband base stations, that can provide us with a product
that meets our quality standards.

COMPETITION


     The wireless telecommunications infrastructure market is highly
competitive. The market for our products is characterized by rapidly changing
technology, evolving industry wireless standards


                                       37
<PAGE>   43


and frequent new product introductions and enhancements. Failure to keep pace
with these changes could seriously harm our competitive position and prospects
for growth. Our ability to compete depends on many factors including product and
standard flexibility, price and reliability.



     Current and potential competitors consist primarily of major domestic and
international companies, most of whom have longer operating histories; larger
installed customer bases; substantially greater name recognition; and greater
financial, technical, manufacturing, marketing, sales and distribution
resources. Competing base station vendors can be divided into two groups:
existing large equipment manufacturers who supply a complete range of wireless
base station systems to wireless service operators and smaller companies that
typically market components of wireless systems to system suppliers or directly
to operators. Our current competitors include Alcatel S.A., Hughes Network
Systems, LM Ericsson Telephone Company, Lucent Technologies Inc., Motorola,
Inc., NEC Corporation, Nokia Corporation, Nortel Networks Corporation and
Siemens AG. We face actual and potential competition not only from these
established companies but from start-up companies that develop and market new
wireless telecommunications products and services.


PROPRIETARY RIGHTS


     We consider our technologies proprietary and seek to protect our
intellectual property rights. We have 33 domestic patents granted, 22 patent
applications pending, and 2 provisional patent applications. In addition, we are
seeking patent protection for our inventions in foreign countries. One of the
allowed domestic patents was based upon proprietary rights originally obtained
from Harris Corporation, one of our stockholders, and is subject to a
non-exclusive cross license to a third party. We also obtained from Harris
Corporation a royalty-free, worldwide, non-exclusive right and license to use
six other patents in the manufacture and sale of products covered by these
patents. Our patents cover the basic architecture of the system, sub-components,
and frequency reuse planning schemes.



     Simultaneously with Motorola's equity investment in January 1995, we signed
an agreement granting Motorola the right to obtain a non-exclusive, royalty-free
license under any two of our patents. In the event of a potential merger,
consolidation or sale of our company, we have the right to require Motorola to
either exercise its right or to cancel its right in exchange for a payment of $1
million per patent. With respect to possible infringement of our respective
digital base station patents, each of us agreed not to enjoin the other and to
attempt dispute resolution, including negotiation of nonexclusive license
agreements in good faith, before resorting to litigation.


     While we believe that our patents will render it more difficult for
competitors to develop and market similar products, our patents may be
invalidated, circumvented, or challenged. Our patent rights may fail to provide
us with competitive advantages. Any pending or future patent applications,
whether or not being currently challenged by applicable governmental patent
examiners, may not be issued with the scope we seek.

     We also rely upon copyright and trade secret laws. Source code for our own
proprietary software is protected as an unpublished copyrighted work and as a
trade secret. In addition, we generally enter into confidentiality or licensing
agreements with employees, consultants, vendors, customers, and licensees, and
generally limit access to the details of proprietary designs, software,
documentation, and other confidential information.

     Notwithstanding our efforts to protect our rights, it may be possible for a
third party to copy or to obtain and use our intellectual property without our
authorization. We may have to pursue litigation in the future to enforce our
proprietary rights or to defend against claims of infringement, although we are
not presently aware of any circumstances that would lead to litigation. Such
litigation could result in substantial costs and diversion of resources and
could seriously harm our business, operating results, and financial condition.
In addition, others may develop technologies superior to our technology,
duplicate our technology, or design around our patents.

GOVERNMENT REGULATION

     Our products must conform to a variety of requirements and protocols. In
order for our products to be used in certain jurisdictions, regulatory approval
may be necessary. The delays inherent in this regulatory approval process may
cause the rescheduling, postponement or cancellation of the installation of
telecommunications systems by our customers which, in turn, may significantly
reduce sales of products to such customers. The failure to comply with current
or future regulations or changes in the interpretation of existing regulations
in a particular country could result in the suspension or cessation of sales in
that country, restrictions on our development efforts and those of our
customers, render current products obsolete, or increase the opportunity for
additional competition. Such regulations or such changes in interpretation could
require us to modify our products and incur substantial costs to comply with
such regulations and changes. Products to support new services can be marketed
only if permitted by frequency allocations and regulations. We only plan to
qualify our products in a foreign country once we have a purchase order from a
customer located there, and this practice may deter customers or contribute to
delays in receiving or filling orders.

EMPLOYEES


     As of September 30, 1999, we had 153 employees. Of these individuals, 97
are in research and product development, 18 are in manufacturing, 14 are in
sales and marketing, 14 are in customer and field services, and 10 are in
finance and administration. We also use contract personnel, primarily for
research and development.


     None of our employees are represented by a labor union and we believe that
our relations with employees are good.

FACILITIES

     Our headquarters consist of approximately 23,400 square feet of space
leased through December 31, 2001, located at 100 Rialto Place in Melbourne,
Florida. The primary manufacturing and product engineering operation is located
at 3950 Dow Road, Melbourne, Florida, consisting of approximately 26,580 square
feet, leased through December 31, 2001. We also maintain a manufacturing and
engineering facility in Westbury, New York, consisting of approximately 12,000
square feet, leased through December 31, 2001. We believe that these facilities
will be adequate to meet our requirements for the foreseeable future and that
suitable additional space will be available if needed.

LEGAL PROCEEDINGS

     On January 21, 1997, we filed a complaint against Amplidyne, Inc. in
Brevard County, Florida, alleging breach of contract and non-performance in
connection with the delivery of certain high-power amplifier units used in our
base stations. We are seeking approximately $4.4 million in damages. Amplidyne
filed an answer alleging certain affirmative defenses and a counterclaim against
us for approximately $463,000. Amplidyne's motion for summary judgment was
denied in February 1999, and the litigation is currently still in a preliminary
stage with discovery not yet completed.

     We are also involved in various claims and litigation matters arising in
the ordinary course of business. We believe that the ultimate outcome of these
matters will not have a material effect on our results of operations or
financial condition.

as amended. No officer serving on the board of directors or the Compensation
Committee has or will participate in decisions awarding compensation or granting
stock options to himself.



     The Nominating Committee consists of Mr. Mullins, Chairman, Mr. Adams, Mr.

DIRECTOR COMPENSATION


     Non-employee directors are entitled to receive option grants and other
awards under the 1999 Equity Incentive Plan. Non-employee directors are
currently entitled to receive an award of nonqualified stock options every three
years, the amount of which is determined by the board of directors in its sole
discretion. These director options will have an exercise price equal to the fair
market value of our common stock when granted and will vest in three annual
installments provided the director has attended at least 75% of board of
director meetings in the 12 months preceding each vesting date, with exception
for special circumstances. Unvested options for a particular year will vest on a
pro rata basis if a director leaves or is removed from office, provided he met
the attendance requirement for the portion of the year he served as a director.
All directors will be reimbursed for expenses incurred in attending meetings of
the board of directors and its committees. In September 1999, each non-employee
director received non-qualified stock options to purchase 7,533 shares of our
common stock at an exercise price of $8.63 per share. In September 1999, we also
issued to Mr. DeMaeyer 7,649 shares of our common stock in satisfaction of
$66,000 of accrued fees due to him for his services as a director under our
prior policy of cash compensation of $1,500 per meeting for independent
directors.


TERM OF EXECUTIVE OFFICERS AND DIRECTORS

     Our directors currently serve terms until the next annual meeting of
stockholders and the election of their successors. At the next annual meeting of
stockholders, the board of directors will be divided into three classes, with
three directors in each class. The Class I directors will be nominated for
election for a term of three years, the Class II directors will be nominated for
election for a term of two years, and the Class III directors will be nominated
for election for a term of one year. Thereafter, each director will serve for a
term of three years. Directors will hold office until the annual meeting of
stockholders in the year in which the term of their class expires and until
their successors have been duly elected and qualified. Executive officers are
appointed by and serve at the discretion of the board.

BENEFIT PLANS



     1999 Equity Incentive Plan.  The 1999 Equity Incentive Plan, which amended
and restated our 1994 Stock Option Plan and Independent Director Stock Option
Plan, provides for the issuance of a maximum of 3,206,842 shares of common stock
pursuant to the grant of incentive stock options, non-qualified stock options,
restricted stock, stock appreciation rights, performance awards and other
stock-based awards to employees, directors and independent contractors. The 1999
Equity Incentive Stock Plan is administered by the Compensation Committee which
has the authority to determine recipients of awards under the Plan. However, the
board of directors must approve all awards granted under the Plan to directors
and employees who are subject to Section 16 of the Securities Exchange Act of
1934, as amended. The exercise price of options and the vesting periods,
expiration dates and other terms of awards under the Plan are determined by the
Compensation Committee or the board of directors. Awards are not transferable
except by will or by the laws of descent and distribution or pursuant to a
qualified domestic relations order. Unless otherwise determined by the board of
directors, in the event of a change of control of our company, all unexercised
stock options granted pursuant to the Plan become fully vested and immediately
exercisable.



     At September 30, 1999, we had granted options for the purchase of 2,190,624
shares of common stock, excluding options that expired upon the termination of
employment of certain employees (which shares are currently reserved for future
grant). Options for the purchase of 286,795 shares had been exercised, and
options for the purchase of 1,903,829 shares remained outstanding. At September
30, 1999, a total of 1,016,218 shares were reserved for grant of options.



     401(k) Plan.  In 1994, we adopted the AirNet Communications Corporation
401(k) Plan covering our full-time employees located in the United States. The
401(k) plan is intended to qualify under Section 401(k) of the Internal Revenue
Code of 1986, as amended, so that contributions to the 401(k) plan by employees,
and the investment earnings thereon, are not taxable to employees until
withdrawn from the 401(k) plan. Pursuant to the 401(k) plan, employees may elect
to reduce their current compensation by up to the lesser of 15% of their annual
compensation or the statutorily prescribed annual limit ($10,000 in 1999) and to
have the amount of the reduction contributed to the 401(k) plan. Commencing
January 1, 2000, we will provide a matching contribution of fifty cents for each
dollar contributed by an employee under the 401(k) plan; provided, that the
aggregate of our matching contributions to any employee in any calendar year
will not exceed 3% of the employee's annual salary.

EMPLOYEE NONCOMPETE AND POST-TERMINATION BENEFITS AGREEMENT



     In October 1999, we entered into an Employee Noncompete and
Post-Termination Benefits Agreement with Dr. Hamilton. Pursuant to this
Agreement, Dr. Hamilton has agreed that he will not compete with us for a period
of one year following any termination of his employment, and we agreed to
continue to provide him with his regular weekly salary and benefits during the
one year noncompetition period so long as his termination was not for cause.
Notwithstanding the foregoing, Dr. Hamilton may elect to terminate the
noncompetition period after nine months, in which case, his right to continue
receiving salary and benefits would also terminate. The Agreement also provides
for accelerated vesting and an extended exercise period with respect to stock
options held by Dr. Hamilton at the time of any termination of his employment.



     Option Grants in Last Fiscal Year.  The following table shows certain
information regarding stock options granted to the executive officers, during
the fiscal year ended December 31, 1998. All of these stock options were granted
under our stock option plan.

(1) The dollar amounts under these columns represent the potential realizable
    value of each grant assuming that the market value of our stock appreciates
    from the date of grant to the expiration of the option at annualized rates
    of 5% and 10%. These assumed rates of appreciation have been specified by
    the SEC for illustrative purposes only and are not intended to forecast
    future financial performance or possible future appreciation in the price of
    our stock. The actual amount the executive officer may realize will depend
    on the extent to which the stock price exceeds the exercise price of the
    options on the date the option is exercised.

                              CERTAIN TRANSACTIONS

COMPANY FORMATION AND SERIES A FINANCING

     Harris Corporation acquired an interest in the Company through HVFM-I, L.P.
in exchange for a contribution of capital and proprietary technology.


     In 1994 and early 1995, we raised approximately $11.9 million in gross
proceeds from the sale of units of our stock to six investors: The P/A Fund,
L.P. f/k/a APA/Fostin Pennsylvania Venture Capital Fund II ($3,000,000), Fostin
Capital Associates II ($1,000,000), HVFM-I, L.P. ($4,440,301), APA Excelsior
III, L.P. ($2,093,808), Coutts & Co. (Jersey), Ltd., Custodian for APA Excelsior
III/Offshore, L.P. ($798,192), and CIN Venture Nominees, Ltd. (an affiliate and
nominee of Excelsior III, L.P.) ($108,000). These six investors paid $1.00 for
each unit, which consisted of one share of Non-Voting Redeemable Preferred
Stock, Series A and one share of common stock.


     The following directors are affiliated with these investors:

     - Joel P. Adams as President of Adams Capital Management manages the
       investments in our company that were made by The P/A Fund, L.P. and
       Fostin Capital Associates II and is a general partner of Fostin Capital
       Partners II, a general partner of The P/A Fund, L.P.;

     - Mr. Adams is also a stockholder and officer of Fostin Capital Corp., a
       general partner of Fostin Capital Associates II;

     - Mr. Mullins is a stockholder, director and President of Venture First
       Associates of Melbourne, the general partner of HVFM-I, L.P.; and

     - Robert M. Chefitz is a General Partner and Vice President of Patricof &
       Co. Ventures, Inc., which manages investments of The P/A Fund, L.P., APA
       Excelsior III, L.P., Coutts & Co. (Jersey), Ltd., Custodian for APA
       Excelsior III/Offshore, L.P., and CIN Venture Nominees, Ltd.

     On January 26, 1995, pursuant to a recapitalization, the six investors
listed above exchanged their shares of Non-Voting Redeemable Preferred Stock,
Series A on a one-for-one basis for shares of our Series A Preferred Stock.

SERIES B FINANCING

     In early 1995, we raised approximately $15.8 million in gross proceeds from
the sale of our Series B Preferred Stock to 18 investors, at a purchase price of
$4.883818833 per share. In connection with Motorola Inc.'s purchase of shares of
Series B Preferred Stock, we entered into an OEM and Patent and License Option
Agreement under which we granted Motorola nonexclusive options to purchase 25
pre-commercial versions of our AdaptaCell base station and other products and
components designed or manufactured by us. Also, under the agreement:


     - Motorola has the right to acquire a worldwide, nonexclusive, royalty-free
       license under any two of our patents (for manufacture of designs by
       Motorola, but not for access to or copying of our designs);



     - in the event of a potential merger, consolidation or sale of our company,
       we have the right to require Motorola to either exercise its right or to
       cancel its right in exchange for a payment of $1 million per patent;



     - with respect to possible infringement of our respective digital base
       station patents, each of us agreed not to enjoin the other and to attempt
       dispute resolution, including negotiation of nonexclusive license
       agreements in good faith, before resorting to litigation; and


     - Motorola may receive discounts on nonexclusive royalty-bearing licenses
       from us.

SERIES C FINANCING

     In July 1995, we raised an aggregate of approximately $30.0 million in
gross proceeds from the sale of shares of our Series C Preferred Stock to 102
investors, at a purchase price of $6.00 per share.

SERIES D FINANCING


     In April 1997, we raised approximately $9.0 million in gross proceeds from
the sale of Series D Preferred Stock to 66 investors, at a purchase price of
$1.10 per share. Substantially all of these funds were invested by existing
Series A, Series B and Series C Preferred stockholders, including HVFM-I, L.P.
($3,500,000), The P/A Fund, L.P. ($1,000,000), Fostin Capital Associates II
($250,000), APA, Excelsior III, L.P. ($1,047,000), Coutts & Co. (Jersey) Ltd.,
Custodian for APA Excelsior III/Offshore, L.P. ($399,000), CIN Venture Nominees,
Ltd. ($54,000) and Milo D. Harrison ($14,740).


1997 BRIDGE FINANCING


     On August 8, 1997, we closed on a 60 day $2 million secured bridge loan
from certain existing holders of our Series A Preferred Stock as follows: APA
Excelsior III, L.P. ($398,857); Coutts & Co. (Jersey) Ltd., Custodian for APA
Excelsior III/Offshore, L.P. ($152,000); CIN Venture Nominees, Ltd. ($20,572);
The P/A Fund, L.P. ($285,714); Fostin Capital Associates II, APA ($142,857); and
HVFM-I, L.P. ($1,000,000). The loans were evidenced by convertible promissory
notes that were secured by a first priority security interest in all our assets
and accrued interest at 16% per annum. The principal under these notes was
automatically converted into $2 million of shares of Series E Preferred Stock
upon the initial closing of the offering of Series E Preferred Stock described
below and the security interests were terminated.


SERIES E FINANCING


     In the second half of 1997, we raised approximately $15.4 million in gross
proceeds from the sale of shares of Series E Preferred Stock to 49 investors, at
a per share purchase price of $.035619838954. A significant portion of the
funding was provided by existing holders of Series A, B, C and D Preferred
Stock, including HVFM-I, L.P. ($2,500,000), The P/A Fund, L.P. ($1,000,000),
Fostin Capital Associates II ($500,000), APA Excelsior III, L.P. ($1,396,000),
Coutts & Co. (Jersey) Ltd., Custodian for APA Excelsior III/Offshore, L.P.
($532,000), CIN Venture Nominees, Ltd. ($72,000) and Milo D. Harrison ($41,183).
In addition to the investments by then-existing stockholders, SCP Private Equity
Partners, L.P. ($5,000,000) and CIP Capital, L.P. ($250,000) invested in Series
E Preferred Stock. James Brown, one of our directors, is a Partner of SCP and
Managing Director of CIP.



     The initial closing of the Series E Offering (including the sale of $6
million of Series E Preferred Stock and the sale of the note and warrant to
Harris Corporation, as described below) was consummated on September 15, 1997.
At this initial closing we sold to Harris Corporation a $4 million Senior
Secured Convertible Promissory Note which was convertible into 112,296,970
shares of Series E Preferred Stock. This note accrued interest at 8% and was
secured by a first priority security interest in all of our assets. On August
28, 1998, Harris Corporation elected to convert this note into 112,296,970
shares of Series E Preferred Stock and the security interests were terminated.
We also issued Harris Corporation a warrant to purchase an additional 169,173
shares of Series E Preferred Stock. Following this offering, the warrant by its
terms becomes exercisable for the same number of our common shares.


     Harris Corporation is the principal investor and limited partner of HVFM-I,
L.P., a holder of shares of Series A, D, E, F and G Preferred Stock, common
stock, and one of the June 1999 convertible promissory notes described below.
Harris Corporation has represented in writing to us that it does not control or
manage HVFM-I, L.P. Nevertheless, Mr. Mullins, a director of our company and a
director and President of Venture First, the general partner of HVFM-I, L.P.,
abstained from the board of director votes approving our transactions with
Harris Corporation.

SERIES F FINANCING


     In late 1998, we raised approximately $15.7 million in gross proceeds from
the sale of Series F Preferred Stock to 31 investors, at a per share purchase
price of $0.05526523774. The lead investor in the Series F Offering was Tandem
PCS Investments, L.P. ($7,000,000) with the remainder of the funding being

G. Coffey, one of our directors, is a Managing Member of the Special Limited
Partner of Tandem PCS Investments, L.P.


1999 BRIDGE FINANCING

     In early June 1999, we closed on loans in an aggregate amount of $800,000
from certain existing stockholders or related affiliates as follows: The P/A
Fund, L.P., APA Excelsior III, L.P., Coutts & Co. (Jersey) Ltd., Custodian for
APA Excelsior III/Offshore, L.P. and CIN Venture Nominees, Ltd. ($200,000);
HVFM-I, L.P. ($200,000); Adams Capital Management, L.P. ($200,000); and SCP
Private Equity Partners ($200,000). The loans were evidenced by demand
promissory notes and accrued interest at the prime rate plus 2% per annum. The
demand notes were canceled and exchanged for convertible promissory notes as
part of the initial closing of our convertible promissory notes and warrant
offering.


     In mid-June 1999, we closed on $6.0 million of convertible promissory notes
along with warrants to purchase approximately 496,663 million shares of our
common stock. In July and August 1999, we closed on an additional $338,187 of
convertible promissory notes along with warrants to purchase approximately
27,656 shares of our common stock. All of the warrants have an exercise price of
$3.67 per share. The purchasers of the convertible promissory notes and
warrants, all of whom are existing stockholders, invested in this offering as
follows: SCP Private Equity Partners ($2,500,000); Adams Capital Management,
Inc. ($600,000); The P/A Fund, L.P., APA Excelsior III, L.P., Coutts & Co.
(Jersey) Ltd., Custodian for APA Excelsior III/Offshore, L.P. and CIN Venture

($2,000,000), Milo D. Harrison ($10,817), and other existing investors
($338,187). The convertible promissory notes were secured by a security interest
in all of our assets.


     The principal and accrued interest under the outstanding convertible
promissory notes was automatically converted into shares of Series G Preferred
Stock upon the closing of the Series G financing.

SERIES G FINANCING


     In September 1999, we raised $30.0 million in gross proceeds from the sale
of Series G Preferred Stock to 45 investors, at a per share purchase price of
$0.13, including conversion of principal and accrued interest under $6.3 million
of the convertible promissory notes issued in the 1999 bridge financing. The
lead outside investors in the Series G offering were Mellon Ventures, Inc.
($5,000,000), Peak Telecommunications Investments, LLC ($3,987,157) and Peak

($1,000,000) and Damac Investors (III) Inc. ($1,000,000) Milo D. Harrison

                          DESCRIPTION OF CAPITAL STOCK


     Under our Sixth Amended and Restated Certificate of Incorporation, which
will be adopted prior to the closing of this offering, our authorized capital
stock will consist of 50,000,000 shares of common stock and 10,000,000 shares of
preferred stock. No other class of capital stock will be authorized. The
following information relates only to our Sixth Amended and Restated Certificate
of Incorporation.


COMMON STOCK


     Upon the closing of this offering, we expect to have 16,723,736 shares of
common stock issued and outstanding, excluding the shares sold in the offering.



     The holders of common stock are entitled to one vote per share on all
matters submitted to a vote of stockholders, including the election of
directors. As of the date of this prospectus, there are 181 holders of record of
our common stock. Our common stock does not have cumulative voting rights, which
means that the holders of a majority of the outstanding common stock voting for
the election of directors can elect all directors then being elected. The
holders of common stock are entitled to receive dividends when, as, and if
declared by the board of directors out of legally available funds. Upon
liquidation or dissolution, the holders of common stock will be entitled to
share ratably in the assets legally available for the distribution to
stockholders after payment of liabilities and subject to the prior rights of any
holders of preferred stock then outstanding. The holders of common stock have no
conversion, sinking fund, redemption, preemptive or subscription rights. The
rights, preferences and privileges of holders of common stock are subject to the
rights of the holders of shares of any series of preferred stock which we may
issue in the future.


PREFERRED STOCK

     We have 10,000,000 shares of undesignated preferred stock authorized for
issuance. Upon the closing of the offering, no shares of preferred stock will be
issued and outstanding.

     Our board of directors may, without further action by our stockholders,
from time to time direct the issuance of preferred stock in one or more series,
and may, at the time of issuance, fix the dividend rights, dividend rates, any
conversion rights or right of exchange, any voting rights, rights and terms of
redemption (including sinking fund provisions), the redemption price or prices,
the liquidation preferences, and any other rights, preferences, privileges, and
restrictions of any series of preferred stock and the number of shares
constituting such series and the designation thereof. We have no present plans
to issue any shares of preferred stock.

WARRANTS


     Warrants issued to Harris Corporation on September 12, 1997 entitle Harris
Corporation to purchase 169,173 shares of our common stock for $2.36 per share.
Such warrants are currently exercisable and expire on September 12, 2002.



     In June and August 1999, we issued warrants to purchase up to 518,319
shares of common stock in connection with our sale of $6.3 million of our
convertible promissory notes and warrants. The exercise price for the warrants
is $3.67 per share. The warrants are currently exercisable and expire on June
10, 2009.


REGISTRATION RIGHTS


     After the 180 day period following the closing of this offering, the
holders of approximately 16,435,949 shares of common stock and holders of
warrants to purchase approximately 687,492 shares of common stock have rights to
require us to register their shares for sale under the Securities Act. Under two
separate agreements with these stockholders, if we propose to register any of
our securities for sale, either for our own account or for the account of
another holder exercising registration rights, these stockholders are entitled
to include their shares in our registration. These stockholders have the right
to demand that we register their shares on two occasions (under each agreement)
on a form other than

                                       53
<PAGE>   59

Form S-3 and on an unlimited number of additional occasions using Form S-3, if
we are eligible to use Form S-3.


     All of the registration rights are subject to conditions and limitations,
including the right of underwriters to limit the number of shares included in a
registration and to exclude holders' shares from a registration initiated by us
for our account. We have agreed to pay the expenses of those registrations in
most cases. We are not required to honor demands for registration within 6
months after the effective date of any registration statement. On one occasion
during any one year period in the case of the former holders of Series E, F and
G preferred stock or any one year period in the case of any former holder of
Series A, B, C or D preferred stock, we can defer demand registration requests
for up to 120 days if our board of directors determines in good faith that a
registration would be materially detrimental to us.



ANTITAKEOVER EFFECTS OF PROVISIONS OF DELAWARE LAW AND OUR CERTIFICATE OF
INCORPORATION AND BYLAWS


     Prior to the consummation of this offering, we will amend and restate our
certificate of incorporation by filing our Sixth Amended and Restated
Certificate of Incorporation with the Secretary of State of the State of
Delaware. Some provisions of our amended and restated certificate of
incorporation, our bylaws and Delaware law could have the effect of making it
more difficult for a third party to acquire a majority of our outstanding voting
stock, even if doing so would be beneficial to our stockholders.

     Classified Board of Directors.  Our amended and restated certificate of
incorporation will provide for the board of directors to be divided into three
classes of directors serving staggered three-year terms. As a result,
approximately one-third of the board of directors will be elected each year.
Holders of a majority of the outstanding shares of capital stock entitled to
vote with respect to an election of directors will be able to remove directors
only for cause. Vacancies on the board of directors may be filled by the
remaining directors.

     Advance Notice Requirements for Stockholder Proposals and Director
Nominations.  Our bylaws establish an advance notice procedure for the
nomination, other than by or at the direction of our board of directors or one
of its committees, of candidates for election as director as well as for other
stockholder proposals to be considered at stockholders' meetings. Notice of
stockholder proposals and director nominations must be timely given in writing
to our secretary prior to the meeting at which the matters are to be acted upon
or the directors are to be elected, and must contain certain information
specified in the bylaws. For notice to be timely, we must receive it at our
principal executive offices not less than 120 days prior to the anniversary date
of the release of our proxy statement in connection with our immediately
preceding annual meeting of stockholders. However, in the event no annual
meeting was held in the previous year or the annual meeting is called for a date
that is not within 60 days before or after such anniversary date, notice by the
stockholder in order to be timely must be received within a reasonable time
before the solicitation is made.

     Blank Check Preferred.  Our board of directors will have the authority to
issue up to 10,000,000 shares of preferred stock and to determine the
preferences, rights and privileges of those shares without any further vote or
action by our stockholders. The rights of the holders and the market value of
our common stock may be adversely affected by the rights of the holders of any
series of preferred stock that may be issued in the future. Furthermore, our
board could, without stockholder approval, use our preferred stock to adopt a
"poison pill" takeover defense mechanism.

     Delaware Anti-Takeover Statute.  Upon the listing of our common stock on
the Nasdaq National Market, we will be subject to Section 203 of the Delaware
General Corporation Law, an anti-takeover statute. 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
following the date the person became an interested stockholder, unless (with
certain exceptions) the "business combination" or the transaction in which the
person became an interested stockholder is approved in a prescribed matter.
Generally, a "business combination" includes a merger, asset or stock sale, or
other transaction resulting in a financial benefit to the interested
stockholder. Generally, an "interested stockholder" is a person who, together
with affiliates and associates, owns (or within three years prior to the
determination of interested
                                       54
<PAGE>   60

stockholder status, did own) 15% or more of a corporation's voting stock. The
existence of this provision could have an anti-takeover effect with respect to
transactions not approved in advance by our board of directors, including
discouraging takeover attempts that might result in you receiving a premium over
the market price for your shares of common stock.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is Continental Stock
Transfer & Trust Company. Their telephone number is 212-509-4000.

                        SHARES ELIGIBLE FOR FUTURE SALE


     Upon completion of this offering, we will have outstanding 22,223,736
shares of common stock, or 23,048,736 shares if the underwriters' over-allotment
option is exercised in full, in each case excluding 687,492 shares underlying
warrants and 2,006,145 shares underlying outstanding options. Of these shares,
all of the shares sold in this offering (5,500,000 shares or 6,325,000 shares if
the underwriters' over-allotment option is exercised in full) will be freely
tradable without restriction or further registration under the Securities Act
except for any shares purchased by an "affiliate", which will be subject to the
limitations of Rule 144 under the Securities Act. As defined in Rule 144 under
the Securities Act, an "affiliate" of an issuer is a person that directly, or
indirectly through the use of one or more intermediaries, controls, is
controlled by or is under common control with such issuer. The remaining
outstanding shares of common stock will be "restricted securities" as defined in
Rule 144 under the Securities Act and may not be resold in the absence of
registration under the Securities Act or pursuant to an exemption from such
registration, including exemptions provided by Rule 144 under the Securities
Act. In addition, we and our executive officers and directors, and other holders
of substantially all of our existing outstanding shares, have agreed not to
offer, sell, contract to sell or otherwise dispose of any common stock or any
securities convertible into or exchangeable for common stock for a period of 180
days after the date of this prospectus without the prior written consent of
Salomon Smith Barney. Immediately following this offering, the existing
stockholders will own 16,723,736 restricted shares, representing approximately
75.25%, 72.56% if the underwriters' over-allotment option is exercised in full,
of the then outstanding shares of common stock. Our executive officers and
directors will own 13,701,460 shares.


     Prior to this offering, there has been no established market for our common
stock and we can make no predictions about the effect, if any, that market sales
of shares or the availability of shares for sale will have on the market price
of our common stock prevailing from time to time. Nevertheless, sales of
substantial amounts of our common stock in the public market, or the perception
that such sales may occur, may cause the market price for our common stock to
decline.

RULE 144

     In general, under Rule 144 as currently in effect, a person, or persons
whose shares must be aggregated, who has beneficially owned restricted shares
for at least one year, including persons who are affiliates, would be entitled
to sell within any three-month period a number of shares that does not exceed
the greater of:


     - one percent of the then outstanding shares of our common stock,
       approximately 222,237 shares immediately after this offering; or


     - the reported average weekly trading volume of our common stock during the
       four calendar weeks preceding a sale by such person.

     Sales under Rule 144 are also subject to certain manner-of-sale provisions,
notice requirements, and the availability of current public information about
us.

RULE 144(k)

     Under Rule 144(k), a person, or persons whose shares must be aggregated,
who has held restricted shares for a minimum of two years and who is not, and
for three months prior to the sale of such shares has not been one of our
affiliates is free to sell such shares immediately following this offering
without regard to the volume, manner-of-sale, and certain other limitations
contained in Rule 144. However, our transfer agent may require an opinion of
counsel that a proposed sale of shares comes within the terms of Rule 144 of the
Securities Act prior to effecting a transfer of the shares. Upon completion of
this offering holders of 15,814,195 shares are eligible to freely sell such
shares under Rule 144(k).

OPTIONS


     Options to acquire 2,006,145 shares of our common stock are outstanding. We
intend to file a registration statement on Form S-8 under the Securities Act to
register all of the shares of our common stock which are issuable upon exercise
of stock options granted or to be granted under the 1999 Equity Incentive Plan.
The filing of this registration statement will allow these shares, other than
those held by members of management who are deemed to be affiliates, to be
eligible for resale without restriction, subject to the lock-up period related
to this offering, or further registration upon issuance to participants. After
the effective date of the registration statement on Form S-8 and, if applicable,
the expiration of the lock-up period related to this offering, shares purchased
upon exercise of options granted pursuant to the 1999 Equity Incentive Plan
generally will be available for resale in the public market by non-affiliates
without restriction. Sales by our affiliates of shares registered on this
registration statement are subject to all of the Rule 144 restrictions except
for the one-year holding period requirement.


     In addition to possibly being able to sell option shares without
restriction under a Form S-8 registration statement when effective, persons
other than our affiliates are allowed under Rule 701 under the Securities Act to
sell shares of our common stock issued upon exercise of stock options beginning
90 days after the date of this prospectus, subject only to the manner of sale
provisions of Rule 144 and to the lock-up period related to this offering. Our
affiliates may also begin selling option shares beginning 90 days after the date
of this prospectus but are subject to all of the Rule 144 restrictions except
for the one-year holding period requirement and for the 180 day lock-up period
related to this offering.

               UNITED STATES TAX CONSEQUENCES TO NON-U.S. HOLDERS


     The following is a general discussion of the material U.S. federal income
tax consequences of the purchase, ownership and disposition of our common stock
to a non-U.S. Holder. For the purpose of this discussion, a non-U.S. Holder is
any holder that for U.S. federal income tax purposes is not a U.S. person. For
purposes of this discussion, the term U.S. person means:


     - a citizen or resident of the U.S.;

     - a corporation or other entity taxable as a corporation and created or
       organized in the U.S. or under the laws of the U.S. or any political
       subdivision thereof;

     - an estate whose income is included in gross income for U.S. federal
       income tax purposes regardless of its source; or

     - a trust whose administration is subject to the primary supervision of a
       U.S. court and which has one or more U.S. persons who have the authority
       to control all substantial decisions of the trust.


     This discussion does not address all aspects of U.S. federal income
taxation that may be relevant in light of a non-U.S. Holder's particular facts
and circumstances, such as being a U.S. expatriate, and does not address any tax
consequences arising under the laws of any state, local or non-U.S. taxing
jurisdiction. Furthermore, the following discussion is based on current
provisions of the Internal Revenue Code of 1986, as amended, the Treasury
Regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all as in effect on the date hereof, and all of which
are subject to change, possibly with retroactive effect. ACCORDINGLY, EACH
NON-U.S. HOLDER SHOULD CONSULT A TAX ADVISOR REGARDING THE U.S. FEDERAL, STATE,
LOCAL AND NON-U.S. INCOME AND OTHER TAX CONSEQUENCES OF ACQUIRING, HOLDING AND
DISPOSING OF SHARES OF OUR COMMON STOCK.


DIVIDENDS

     We have never paid dividends on our common stock and do not expect to pay
any cash dividends on our common stock for the foreseeable future. In the event,
however, that we do pay dividends on our common stock, any dividend paid to a
non-U.S. Holder of common stock generally will be subject to U.S. withholding
tax either at a rate of 30% of the gross amount of the dividend or such lower
rate as may be specified by an applicable tax treaty. Dividends received by a
non-U.S. Holder that are effectively connected with a U.S. trade or business
conducted by the non-U.S. Holder are exempt from such withholding tax. However,
those effectively connected dividends, net of certain deductions and credits,
are taxed at the same graduated rates applicable to U.S. persons.

     In addition to the graduated tax described above, dividends received by a
corporate non-U.S. Holder that are effectively connected with a U.S. trade or
business of the corporate non-U.S. Holder may also be subject to a branch
profits tax at a rate of 30% or such lower rate as may be specified by an
applicable tax treaty.

     A non-U.S. Holder of common stock that is eligible for a reduced rate of
withholding tax pursuant to a tax treaty may obtain a refund of any excess
amounts currently withheld by filing an appropriate claim for refund with the
IRS.

GAIN ON DISPOSITION OF COMMON STOCK

     A non-U.S. Holder generally will not be subject to U.S. federal income tax
on any gain realized upon the sale or other disposition of our common stock
unless:

     - the gain is effectively connected with a U.S. trade or business of the
       non-U.S. Holder (which gain, in the case of a corporate non-U.S. Holder,
       must also be taken into account for branch profits tax purposes);

     - the non-U.S. Holder is an individual who holds his or her common stock as
       a capital asset (generally, an asset held for investment purposes) and
       who is present in the U.S. for a period or
                                       58
<PAGE>   64

       periods aggregating 183 days or more during the calendar year in which
       the sale or disposition occurs and certain other conditions are met; or

     - we are or have been a "United States real property holding corporation"
       for U.S. federal income tax purposes at any time within the shorter of
       the five-year period preceding the disposition or the holder's holding
       period for our common stock. We have determined that we are not and do
       not believe that we will become a "United States real property holding
       corporation" for U.S. federal income tax purposes.

BACKUP WITHHOLDING AND INFORMATION REPORTING

     Generally, we must report annually to the IRS the amount of dividends paid,
the name and address of the recipient, and the amount, if any, of tax withheld.
A similar report is sent to the holder. Pursuant to tax treaties or other
agreements, the IRS may make its reports available to tax authorities in the
recipient's country of residence.

     Dividends paid to a non-U.S. Holder at an address within the U.S. may be
subject to backup withholding at a rate of 31% if the non-U.S. Holder fails to
establish that it is entitled to an exemption or to provide a correct taxpayer
identification number and other information to the payer. Backup withholding
generally will not apply to dividends paid to non-U.S. Holders at an address
outside the U.S. on or prior to December 31, 2000 unless the payer has knowledge
that the payee is a U.S. person. Under recently finalized Treasury Regulations
regarding withholding and information reporting, payment of dividends to
non-U.S. Holders at an address outside the U.S. after December 31, 2000 may be
subject to backup withholding at a rate of 31% unless such non-U.S. Holder
satisfies various certification requirements.

     Under current Treasury Regulations, the payment of the proceeds of the
disposition of common stock to or through the U.S. office of a broker is subject
to information reporting and backup withholding at a rate of 31% unless the
holder certifies its non-U.S. status under penalties of perjury or otherwise
establishes an exemption. Generally, the payment of the proceeds of the
disposition by a non-U.S. Holder of common stock outside the U.S. to or through
a foreign office of a broker will not be subject to backup withholding but will
be subject to information reporting requirements if the broker is:

     - a U.S. person;

     - a "controlled foreign corporation" for U.S. federal income tax purposes;
       or

     - a foreign person 50% or more of whose gross income for certain periods is
       from the conduct of a U.S. trade or business

unless the broker has documentary evidence in its files of the holder's non-U.S.
status and certain other conditions are met, or the holder otherwise establishes
an exemption. Neither backup withholding nor information reporting generally
will apply to a payment of the proceeds of a disposition of common stock by or
through a foreign office of a foreign broker not subject to the preceding
sentence.

     In general, the recently promulgated final Treasury Regulations, described
above, do not significantly alter the substantive withholding and information
reporting requirements but would alter the procedures for claiming benefits of
an income tax treaty and change the certifications procedures relating to the
receipt by intermediaries of payments on behalf of the beneficial owner of
shares of common stock. Non-U.S. Holders should consult their tax advisors
regarding the effect, if any, of those final Treasury Regulations on an
investment in our common stock. Those final Treasury Regulations generally are
effective for payments made after December 31, 2000.

     Backup withholding is not an additional tax. Rather, the tax liability of
persons subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained, provided that the required information is furnished to the IRS.

</TABLE>


     The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in this offering are subject to
approval of particular legal matters by counsel and to other conditions. The
underwriters are obligated to purchase all the shares, other than those covered
by their over-allotment option described below, if they purchase any of the
shares.

     The underwriters, for whom Salomon Smith Barney Inc., Hambrecht & Quist LLC
and Volpe Brown Whelan & Company, LLC are acting as representatives, propose to
offer some of the shares directly to the public at the public offering price set
forth on the cover page of this prospectus and some of the shares to certain
dealers at the public offering price less a concession not in excess of $
per share. The underwriters may allow, and such dealers may reallow, a discount
not in excess of $     per share on sales to certain other dealers. If all the
shares are not sold at the initial offering price, the underwriters may change
the public offering price and other selling terms. The representatives have
advised us that the underwriters do not intend to confirm any sales to any
accounts over which they exercise discretionary authority.


     We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to 825,000 additional shares of our
common stock at the public offering price less the underwriting discount. The
underwriters may exercise this option solely for the purpose of covering
over-allotments, if any, in connection with this offering. To the extent this
option is exercised, each underwriter will be obligated, subject to some
conditions, to purchase a number of additional shares approximately
proportionate to such underwriter's initial purchase commitment.



     At our request, the underwriters will reserve up to five percent (5%) of
the shares of our common stock to be sold, at the initial public offering price,
to our directors, officers and employees, as well as to some of our customers
and suppliers. This directed share program will be administered by Salomon Smith
Barney Inc. The number of shares of common stock available for sale to the
general public will be reduced to the extent these individuals purchase 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
by this prospectus. We have agreed to indemnify the underwriters against certain
liabilities and expenses, including liabilities under the Securities Act of 1933
in connection with sales of the directed shares.



     We, our officers and directors and holders of substantially all of our
existing outstanding shares have agreed that, for a period of 180 days from the
date of this prospectus, we will not, without the prior written consent of
Salomon Smith Barney Inc., dispose of or hedge, any shares of our common stock
or any securities convertible into, or exercisable or exchangeable for, our
common stock. Salomon Smith Barney Inc., in its sole discretion, may release any
of the securities subject to these lock-up agreements at any time without
notice.

     Prior to this offering, there has been no public market for our common
stock. Consequently, the initial offering price for the shares was determined by
negotiation among us and the representatives. Among the factors considered in
determining the initial public offering price were:

     - our record of operation;

     - our current financial condition;

     - our future prospects;

     - our markets;

     - the economic conditions in and future prospects for the industry in which
       we compete;

     - our management; and

     - currently prevailing general conditions in the equity securities markets,
       including current market valuations of publicly traded companies
       considered comparable to us.

The prices at which the shares will sell in the public market after this
offering may, however, be lower than the price at which they are sold by the
underwriters. Additionally, an active trading market in our common stock may not
develop and continue after this offering.


     We have applied to have our common stock included for quotation on the
Nasdaq National Market under the symbol "ANCC".


     The following table shows the underwriting discounts and commissions that
we will pay to the underwriters 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 common stock.

     In connection with this offering Salomon Smith Barney Inc., on behalf of
the underwriters, may purchase and sell shares of common stock in the open
market. These transactions may include over-allotment, syndicate covering
transactions and stabilizing transactions. Over-allotment involves syndicate
sales of shares in excess of the number of shares to be purchased by the
underwriters in this offering, which creates a syndicate short position.
Syndicate covering transactions involve purchases of the shares in the open
market after the distribution has been completed in order to cover syndicate
short positions. Stabilizing transactions consist of certain bids for or
purchases of shares made to prevent or retard a decline in the market price of
the shares while this offering is in progress.

     The underwriters may also impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney Inc., in covering syndicate short positions or making
stabilizing purchases, repurchases shares originally sold by that syndicate
member.

     Any of these activities may cause the price of the shares to be higher than
it would otherwise be in the open market in the absence of such transactions.
Salomon Smith Barney Inc. may effect these transactions on the Nasdaq National
Market or in the over-the-counter market, or otherwise and may discontinue them
at any time.


     We estimate that our total expenses for this offering will be $5.9 million.


     The representatives or their respective affiliates may in the future
perform various investment banking and advisory services for us from time to
time, for which they will receive customary fees. The representatives may, from
time to time, engage in transactions with and perform services for us in the
ordinary course of business.

     We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make in respect of any of those
liabilities.

                                    EXPERTS


     The financial statements of AirNet Communications Corporation as of June
30, 1999 and December 31, 1998 and for the six-month period ended June 30, 1999
and the year ended December 31, 1998 included in this prospectus have been
audited by Deloitte & Touche LLP, independent auditors, as stated in their
report appearing herein, and are included in reliance upon the report of such
firm given upon their authority as experts in accounting and auditing.


     The financial statements of AirNet Communications Corporation at December
31, 1997 and for each of the two years in the period ended December 31, 1997
appearing in this prospectus and registration statement have been audited by
Ernst & Young LLP, independent auditors, as set forth in their report thereon
appearing elsewhere herein, and are included in reliance upon the authority of
such firm as experts in accounting and auditing.

                       CHANGE IN INDEPENDENT ACCOUNTANTS

     On August 6, 1999, we engaged Deloitte & Touche LLP as our independent
accountants for the fiscal year ended December 31, 1998 to replace Ernst & Young
LLP, who we dismissed as our independent accountants effective August 5, 1999.
The decision to change accountants was approved by our board of directors upon
the recommendation of the audit committee.

     The reports of Ernst & Young on our financial statements for 1996 and 1997
did not contain an adverse opinion or disclaimer of opinion and were not
qualified or modified as to uncertainty, audit scope or accounting principles.
In connection with the audits of our financial statements for the fiscal years
ended December 31, 1996 and 1997, and in the subsequent interim period preceding
the dismissal of Ernst & Young, except as disclosed in the following paragraph,
there were no disagreements with Ernst & Young on any matters of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure which, if not resolved to the satisfaction of Ernst & Young would have
caused Ernst & Young to make a reference to the matter in their report. During
the two most recent fiscal years and subsequent interim period preceding the
dismissal of Ernst & Young, we have not been advised of any matters described in
Regulation S-K, Item 304(a)(1)(v) of the Securities Act.

     During 1999, we asked Ernst & Young for advice about the possibility of
changing our revenue recognition policies for the year ending December 31, 1999
and thereafter. We expressed our opinion that revenue should be recognized upon
shipment of our products. Ernst & Young informed us that we could not recognize
revenue until all uncertainties about customer acceptance had been resolved
pursuant to the requirements of AICPA SOP 97-2.

     Although the audit committee of our board of directors had preliminary
discussions with Ernst & Young regarding our revenue recognition policies in a
February 1999 meeting, neither the audit committee nor our board of directors
had any subsequent discussions with Ernst & Young.

     We have not changed our revenue recognition policies.


     We authorized Ernst & Young to respond fully to the inquiries of Deloitte &
Touche regarding our revenue recognition policies. We requested that Ernst &
Young furnish us with a letter addressed to the Securities and Exchange
Commission stating whether or not they agree with the above statements. A copy
of such letter is filed as an exhibit to the registration statement which
includes this prospectus.


                                       63
<PAGE>   69

     Prior to engaging Deloitte & Touche as our new independent accountants:

     - we requested advice from Deloitte & Touche concerning the revenue
       recognition issues referenced above. Deloitte & Touche did not provide us
       with advice.

     - we did not consult with Deloitte & Touche regarding the type of audit
       opinion that might be rendered by them or items that were or should have
       been subject to the AICPA's Statement on Auditing Standards No. 50,
       "Reports on the Application of Accounting Principles."

     We have requested that Deloitte & Touche review the above disclosures
regarding our change in accountants and have given them the opportunity to
furnish us with a letter addressed to the Securities and Exchange Commission in
which Deloitte & Touche may include new information, clarify our statements on
the change in accountants or disclose the respects in which they disagree with
the statements made by us in this prospectus regarding our change in
accountants. If Deloitte & Touche elects to submit such a letter to the
Securities and Exchange Commission, we will file the letter as an exhibit to the
registration statement when received.

                             ADDITIONAL INFORMATION

     We have filed a registration statement on Form S-1 with the Securities and
Exchange Commission under the Securities Act with respect to the shares offered
in this offering. This prospectus, which constitutes a part of the registration
statement, does not contain all the information set forth in the registration
statement, parts of which are omitted as permitted by the rules and regulations
of the Commission. Statements contained in this prospectus as to the contents of
any contract, agreement or other document referred to are not necessarily
complete. For further information pertaining to us and our common stock, we
refer you to our registration statement and the exhibits and schedules thereto,
copies of which may be inspected without charge at the public reference section
of the Commission at 450 Fifth Street, NW, Washington, DC 20549 and at the
regional offices of the commission located at 75 Park Place, New York, New York
10007, and Northwestern Atrium Center, Suite 1400, 500 West Madison Street,
Chicago, Illinois 60661. Copies of all or any portion of the registration
statement may be obtained from the Commission at prescribed rates. In addition,
the Commission maintains a web site that contains reports and other information
that is filed through the Commission's EDGAR System. The web site can be
accessed at http://www.sec.gov.

     We intend to furnish our stockholders with annual reports containing
audited financial statements and an opinion thereon expressed by independent
certified public accountants. We also intend to furnish other reports as we may
determine or as required by law.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors of
AirNet Communications Corporation:

We have audited the accompanying balance sheets of AirNet Communications
Corporation (the Company) as of June 30, 1999 and December 31, 1998, and the
related statements of operations, stockholders' equity, and cash flows for the
six-month period ended June 30, 1999 and the year ended December 31, 1998. 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 in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Company at June 30, 1999
and December 31, 1998, and the results of its operations and its cash flows for
the six-month period ended June 30, 1999 and the year ended December 31, 1998 in
conformity with generally accepted accounting principles.

                       AIRNET COMMUNICATIONS CORPORATION

                         NOTES TO FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


     Nature of Operations -- AirNet Communications Corporation (the Company or
AirNet) is engaged in the design, development, manufacture, and installation of
broadband, software-defined base stations, base station controllers, and related
wireless infrastructure components for wireless telecommunications in the Global
Systems for Mobile Communications (GSM) market. This product and service line
represents the Company's one reportable segment as defined by Statement of
Financial Accounting Standards No. 131, Disclosures about Segments of an
Enterprise and Related Information. The Company was founded in 1994 and is
incorporated in the state of Delaware.


     Development Stage Enterprise -- Prior to January 1, 1998, the Company was
considered a development stage company under Statement of Financial Accounting
Standards No. 7, Accounting and Reporting by Development-Stage Enterprises,
issued by the Financial Accounting Standards Board (FASB), as the Company's
operations principally involved research, development and refinement of the
product and production process, and other business planning activities from
which it was not deriving significant revenues. The total deficit accumulated
during the development stage was $66,047,778.

     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, the disclosure of contingent assets and liabilities at the date of
the financial statements, and the reported amounts of revenue and expenses
during the reporting period. Actual results could differ from those estimates.

     Vulnerability Due to Certain Concentrations and Other Risks -- The Company
performs ongoing credit evaluations of its customers' financial conditions and
generally does not require collateral on accounts receivable; hence, the
accounts receivable are unsecured and the Company is at risk to the extent such
amounts become uncollectible. Customers are billed as contractual milestones are
met, including deposits of up to 50% of the contracted amount at the inception
of the contract. However, collection of the entire amounts due under the
Company's contracts to date have lagged behind shipment of products due to the
substantial time period between shipment and the fulfillment of post-shipment
contractual obligations. As of June 30, 1999 and December 31, 1998 and 1997, two
customers represented 91 percent, 97 percent, and 100 percent, respectively, of
accounts receivable, with one customer representing 69 percent, 58 percent, and
56 percent, respectively, of accounts receivable.

     The Company's customers are comprised primarily of cellular service
providers. To date, all of the Company's sales have been to customers in the
United States, wherein communications are subject to the regulations imposed by
the U.S. Federal Communications Commission.

     The Company's future results of operations involve a number of significant
risks and uncertainties. Factors that could affect the Company's future
operating results and cause actual results to vary materially from expectations
include, but are not limited to, dependence on key personnel, dependence on a
limited number of customers, ability to design new products, product
obsolescence, ability to generate consistent sales, ability to finance research
and development, government regulation, technological innovations and
acceptance, competition, reliance on certain vendors, credit and risks
associated with the Year 2000.

     Long-Lived Assets -- At January 1, 1996, the Company adopted Statement of
Financial Accounting Standards No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets To Be Disposed Of (Statement 121),
which requires that long-lived assets and certain identifiable intangibles to be
held and used by an entity should be reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. To the extent the estimated future cash flows (undiscounted and
without interest) attributable to the assets, less estimated future cash
outflows, are less than the carrying amount, an impairment loss is recognized.
The amount of the loss is measured by the difference between the asset carrying
value and its fair value less costs to sell.
                                       F-8
<PAGE>   78
                       AIRNET COMMUNICATIONS CORPORATION

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

As a result of the adoption of Statement 121, the Company recorded an impairment
loss on analog-based equipment in the amount of approximately $812,000 in 1996.
No impairment losses were recorded in 1997, 1998, or the six-month period ended
June 30, 1999.

     Comprehensive Income -- In June 1997, the FASB issued Statement of
Financial Accounting Standards No. 130, Reporting Comprehensive Income
(Statement 130), effective for fiscal years beginning after December 15, 1997.
Statement 130 establishes standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
Comprehensive income includes all changes in equity during a period except those
resulting from investments by owners and distributions to owners. The Company
adopted Statement 130 in 1998; however, there were no changes in equity during
1998 and for the six-month period ended June 30, 1999 exclusive of investments
by owners and losses from operations. As such, the comprehensive loss for all
periods presented is equal to the amount shown on the statement of operations as
net loss.

     Stock-Based Compensation -- In October 1995, the FASB issued Statement of
Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation
(Statement 123), effective for fiscal years beginning after December 15, 1995.
Statement 123 requires expanded disclosures of stock-based compensation
arrangements and encourages (but does not require) compensation cost to be
measured based on the fair value of the equity instrument awarded. Companies are
permitted, however, to continue to apply Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees (APB 25), which recognizes
compensation cost based on the intrinsic value of the equity instrument awarded.
The Company will continue to apply APB 25 to its employee stock-based
compensation awards. (See Note 6 for the effect on net loss if the Company had
applied the fair value method as prescribed by Statement 123.)

     Financial Instruments -- The carrying amounts reported in the balance sheet
under cash and cash equivalents, accounts receivable, accounts payable and notes
payable approximate fair value due to the immediate or short-term maturity of
these financial instruments.

     Fair value estimates are made at a specific point in time and are based on
relevant market information and information about the financial instrument; they
are subjective in nature and involve uncertainties and matters of judgement and,
therefore, cannot be determined with precision. These estimates do not reflect
any premium or discount that could result from offering for sale at one time the
Company's entire holdings of a particular instrument. Changes in assumptions
could significantly affect these estimates.

     Cash Equivalents -- The Company considers all highly liquid investments
with a maturity of three months or less when purchased to be cash equivalents.
As of June 30, 1999, the Company had cash and cash equivalent balances totaling
$9,431,725 in financial institutions, which were in excess of federally insured
amounts. The Company's policy is to invest excess funds in only well capitalized
financial institutions.


     Inventory -- Inventory is valued at the lower of cost (determined by the
first-in, first-out basis) or market. Inventories are reviewed periodically and
items considered to be slow moving or obsolete are written down to their
estimated net realizable value. During 1996, the Company recorded a write down
of approximately $5,459,000 on analog-based equipment as a result of
discontinued development efforts related to the Company's analog base station.
Finished goods delivered to customers are recorded in inventory until the
related revenue is recognized.


     Property and Equipment -- Property and equipment is stated at cost.
Depreciation is computed by the straight-line method over the estimated useful
lives of the related assets, which ranges from two to five years. Assets held
under capital leases and leasehold improvements are amortized over the life of
the related leases and the amounts are included in depreciation.

     Intangible Assets -- On January 18, 1994, the Company capitalized $440,289
of patent costs transferred by an initial investor to the Company in exchange
for 6,633 shares of the Company's Series A nonvoting convertible cumulative
preferred stock and 6,615 shares of common stock. Recoverability of the
intangible asset was assessed using estimated undiscounted cash flows of related
operations. The intangible asset was amortized over five years using the
straight-line method, and as such, was fully amortized in 1998. The unamortized
balance of the intangible asset prior to 1998 is included in Other Long-Term
Assets on the accompanying balance sheet as of December 31, 1997.



     Revenue Recognition -- Revenue from product sales is recognized after
delivery and resolution of any uncertainties regarding satisfaction of all
significant terms and conditions of the customer contract, which include
completion of installation and customer acceptance of product technical
performance. Given the Company's limited operating history, such uncertainties
have been considered resolved to date when the customer has either placed the
products in service or completed specified testing procedures. Resolution of
such uncertainties is partly dependent on factors outside of the Company's
control. Revenues on products shipped, which have not met the foregoing
conditions, are deferred until such time that the conditions are satisfied.
Historically, the time period over which satisfaction of such conditions has
occurred has varied widely and has been substantial. Sales of the Company's
products are not subject to right of return. Sales of services are recognized at
the time of performance.


     Warranty and Customer Support -- The Company typically warrants its
products against defects in materials and workmanship for a period of one year
from the date of revenue recognition. A provision for estimated future warranty
and customer support is recorded when revenue is recognized. To date, warranty
and customer support costs have not been material.

     Research and Development Expenses -- Expenditures relating to the
development of new products and processes, including significant improvements to
existing products, are expensed as incurred. These expenses include continued
product development and engineering support costs for test development and
technical services.

     Income Taxes -- The Company accounts for income taxes under the asset and
liability method. Under this method, deferred income taxes are recognized for
the tax consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred taxes of a change in tax rates is recognized in
income in the period that the change in the rate is enacted.


     Loss per Share -- Basic loss per share is computed by dividing the net loss
attributable to common stockholders by the weighted average number of common
shares outstanding. The Company has incurred losses since inception. Net loss
attributable to common stockholders is computed by adding dividends accrued but
unpaid on cumulative preferred stocks to the net loss reported. Diluted net loss
per share

3. SENIOR SECURED CONVERTIBLE PROMISSORY NOTE PAYABLE


     On September 12, 1997, the Company entered into a Convertible Note and
Warrant purchase agreement with Harris Corporation (Harris), pursuant to which
Harris purchased a secured convertible promissory note and a warrant for
$4,000,000. The Harris note was secured by all assets of the Company and bears
interest at an annual rate of 8 percent. The Harris note was convertible into
1,691,729 shares of the Company's Series E voting cumulative preferred stock,
and the Harris warrant was exercisable for the purchase of an additional 169,173
shares of Series E voting cumulative preferred stock at a warrant exercise price
of $2.39 per share. The warrant expires on September 12, 2002. The fair value of
the Harris warrant was calculated at $112,297 at the date of grant using the
minimum valuation model. This fair value was accounted for as a discount on the
note, and was being amortized over the life of the note.



     Harris exercised its right of conversion of the note in September 1998 and
received 1,691,729 shares of the Company's Series E voting convertible preferred
stock and the note was canceled. The warrant remained outstanding at June 30,
1999.


4. BRIDGE FINANCING

     Through a private placement in June 1999, the Company issued $6,000,000 of
securities comprised of convertible promissory notes (Bridge Notes) with
attached warrants (the Bridge Warrants). The investors are also preferred
stockholders. The Bridge Notes, which mature on December 11, 2000, bear interest
at a rate of prime plus 2 percent (9.75 percent at June 30, 1999), payable upon
maturity. The Bridge Notes are collateralized by a security interest in all
assets of the Company, subordinated to a first lien for any debt incurred to
finance receivables and inventory. The conversion feature of the Bridge Notes is
automatically initiated in the event that the Company closes on a private
financing of at least $10 million or closes on an initial public offering (IPO)
of the Company's common stock. In the event of the private financing, the
amounts outstanding will be converted into the security issued in such
financing. As of September 16, 1999, the principal and accrued interest on this
financing was converted into Series G senior voting convertible preferred stock
(see Note 11).


     The Bridge Warrants vest immediately, have a ten-year term, and contain a
cashless exercise option. Warrants to purchase 490,663 shares of common stock at
$3.67 per share were issued. The Bridge Warrants expire on June 11, 2009. The
fair value of the Bridge Warrants was calculated at $243,299 at the date of
grant using the fair value method. This fair value was accounted for as a
discount on the Bridge Notes, and is being amortized over the life of the Bridge
Notes.

     Dividends contractually accrue quarterly whether or not declared by the
Board of Directors and regardless of profits, surplus or other funds legally
available for payment. All unpaid cash dividends will be cancelled in the event
of an underwritten public offering of the Company's common stock of at least $20
million. Holders of Series F and E preferred stocks are entitled to receive cash
dividends in preference to any dividends payable on common stock or Series A
through D preferred stocks. Holders of Series D preferred stock are entitled to
receive cash dividends in preference to any dividends payable on common

C preferred stock until all dividends that accrued on Series A and B preferred
stocks prior to the sale of Series C preferred stock have been paid. Thereafter
Series A through C rank equally with regard to the payment of dividends.

series of stock (66.67 percent for Series F).

available for distribution, if any, were distributed among the holders of Series
E and F preferred stocks in proportion to the number of shares of common stock
of the Company into which their respective shares of Series E and F preferred
stocks are convertible as of the date of liquidation.

     Voting -- Holders of preferred stocks have the right to one vote for each
share of common stock issuable upon conversion. So long as any shares of Series
E or F preferred stocks remain outstanding, the Company shall not, without the
vote or written consent of at least a majority of the voting power of those
stockholders (voting together as a single class), approve certain transactions,
including any creation or issuance of additional common stock, merger, sale of
substantially all the assets of the Company, liquidation of the Company,
acquisition transaction, payment of dividends or repurchase of preferred stocks.

     The written consent of the holders of at least 60 percent of the
outstanding shares of preferred stocks (Series A through D) is required to amend
the rights and privileges of the Series A through D preferred stocks, increase
the number of authorized shares, create another class of capital stock, or merge
with another corporation.

     The written consent of the holders of 60 percent of the voting power of
Series E preferred stock and 66.67 percent of Series F preferred stock is
required to approve any change in the rights and privileges of the holders of
the Series E or F preferred stocks, to authorize issuance of any parity
securities, make any dividends or other distributions, or issue common stock or
preferred stocks.

     Preemptive Rights -- Holders of preferred stocks have the preemptive rights
to purchase, on a pro rata basis, any new securities, except common stock in an
underwritten public offering and shares reserved for issuance on grant of stock
options under the option plans noted in Note 6, which the Company may issue.

6. STOCK COMPENSATION PLANS

     The outstanding options expire at various dates through December 2009. At
June 30, 1999, a total of 558,626 shares were exercisable, with a weighted
average exercise price of $1.33 per share. The weighted average remaining
contractual life of options at June 30, 1999 with exercise prices ranging from
$0.066 to $3.32 is 6.1 years. The weighted average fair value of the options
issued during the six-month periods ended June 30, 1999 and (unaudited) 1998 was
$2.66 and $1.33, respectively, and for the year ended December 31, 1998 was
$1.33. No compensation expense has been recorded related to the issuance of
these options. At June 30, 1999, a total of 386,056 shares of the Company's
common stock were available for future grants of stock warrants and options.


     Pro forma information regarding net loss is required by Statement 123 and
has been determined as if the Company had accounted for its employee stock

     The effect of applying Statement 123's fair value method to the Company's
stock options granted in 1996 and 1997 results in a net loss that was not
materially different from the amount presented.

7. EMPLOYEE RETIREMENT PLAN

     The Company sponsors a retirement plan for all employees through a salary
deduction 401(k) savings plan. Employees are permitted to contribute to the plan
up to 15 percent of eligible wages, not to exceed the maximum amount allowable
by law. The Company has not historically matched employee contributions.
Employees are 100 percent vested upon entering the plan.

8. INCOME TAXES


     At June 30, 1999, the Company has net operating loss carryforwards
available to offset future taxable income of approximately $80,615,000 expiring
at various dates through 2019. In addition, the Company has available
approximately $1,255,000 of research and development tax credit carryforwards,
expiring at various dates through 2018, which may be used to offset future
regular tax liabilities. The benefit of the net operating loss carryforwards has
been fully offset by a valuation allowance. U.S. tax rules impose limitations on
the use of net operating losses and tax credits following certain defined
changes in ownership. The Company has not completed the complex analysis
required by the Internal Revenue Code to determine if an ownership change has
occurred. If such a change were deemed to have occurred, the limitation could
reduce or eliminate the amount of these benefits that would be available to
offset future taxable income each year, starting with the year of ownership
change.


     A reconciliation of statutory income tax rate to the Company's effective
tax rate is as follows:

     Agreements -- Simultaneously with its equity investment in January 1995,
Motorola, Inc. (Motorola) entered into an agreement with the Company whereby
Motorola was granted the right to obtain non-exclusive, royalty-free licenses
under any two of AirNet's patents of Motorola's choice. In return, the Company
and Motorola have agreed not to enjoin the other and to negotiate license
agreements in good faith with respect to possible patent infringement. In the
event of a merger, consolidation or sale of AirNet, the Company has the option
to require Motorola to either exercise its right to obtain such licenses or to
cancel such right in exchange for a payment by AirNet of $1 million per patent.


     The Company has entered into Change of Control Severance and Bonus
Agreements (the Agreements) with four key employees. Under the Agreements, the
Company is obligated to pay the key employees twelve months salary upon a
Termination Event (as defined in the Agreements). A Bonus Payment (as defined)
equal to the greater of .05 percent to 2 percent of all consideration in excess
of $50 million or 15 percent of the employee's annual salary shall be paid in
the event of a change in control. Also, if the Company is acquired during 1999
or 2000 for a price of greater than $25 million, then all employees of the
Company (excluding the key employees aforementioned) would receive a bonus of 15
percent of their annual salary, pro rated if an employee has been employed with
the Company for less than one year. The Agreements terminate upon the issuance
of any underwritten public offering of the Company's common stock.

     In April 1998, the Company entered into a Special Outside Director
Acquisition Bonus Pool (the Director Bonus Pool) with three directors. In the
event the Company is acquired, the Director Bonus Pool is determined by the sale
price in excess of $50 million. For every $1 million in excess of $50 million,
the Director Bonus Pool increases by $3,000. The total amount is divided between
these three directors

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

according to a formula approved by the board of directors. The Director Bonus
Pool terminates on the earlier of December 31, 1999 or the closing of an
underwritten public offering.

     Litigation -- In January 1997, the Company filed a complaint seeking
$4,400,000 in damages against a vendor alleging breach of contract and
nonperformance in connection with the delivery of certain high-power amplifier
units used in the Company's base stations. The defendant vendor has filed an
answer alleging certain affirmative defenses and a counterclaim against the
Company in the amount of approximately $463,000. The defendant's motion for
summary judgment was denied in February 1999, and the litigation is currently
still in a preliminary stage with discovery not yet completed.

     The Company is also involved from time to time in various claims and
litigation matters arising in the ordinary course of business. Management
believes that the ultimate outcome of these matters will not have a material
effect on the Company's results of operations or financial condition.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.


     Our officers and directors are covered by provisions of the Delaware
General Corporation Law and our certificate of incorporation and bylaws, which
serve to limit, and, in some instances, to indemnify them against, liabilities
which they may incur in their respective capacities. Our certificate of
incorporation limits the liability of our directors to the fullest extent
permitted by Delaware law. Specifically, the directors of the Company will not
be personally liable for monetary damages for breach of a director's fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Company or its shareholders, (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) for unlawful payments of dividends or unlawful stock repurchases
or redemptions, or (iv) for any transaction from which the director derived an
improper personal benefit.

     Our bylaws provide for the indemnification of our directors and officers
(as well as certain other persons) if the person acted in good faith and in a
manner reasonably believed to be in or not opposed to our best interests, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe the conduct was unlawful. In an action by or in the right of the
Company, no indemnification may be made if the person shall have been adjudged
to be liable to the Company unless the court in which the action was brought
determines upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, the person is fairly and reasonably
entitled to indemnity for the expenses which the court deems proper. Our bylaws
also provide that any indemnification (unless ordered by a court) may be made by
the Company only as authorized in the specific case upon a determination that
indemnification is proper in the circumstances because the person has met the
applicable standard of conduct. This determination must be made (i) by the board
of directors by a majority vote of a quorum consisting of directors who were not
parties to the action, (ii) if a quorum is not obtainable, or, even if
obtainable, a quorum of disinterested directors so directs, by independent legal
counsel in a written opinion, or (iii) by the shareholders of the Company. If an
indemnified person has been successful on the merits or otherwise in defense of
any action described above, or in the defense of any matter in the action, the
person will be indemnified against expenses (including attorneys' fees) incurred
in connection with the action, without the necessity of authorization in the
specific case. Expenses incurred in defending or investigating a threatened or
pending action may be paid by us in advance of the final disposition of the
action upon receipt of an undertaking by the person to repay the amount if it is
ultimately determined that indemnification is not proper. The indemnification
and advancement of expenses provided by or granted
                                      II-1
<PAGE>   97

under our bylaws are not exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement, contract, vote of shareholders or disinterested directors or
otherwise, it being our policy that indemnification of the persons specified in
the bylaws shall be made to the fullest extent permitted by law. The
indemnification and advancement of expenses provided by our bylaws, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director or officer and inure to the benefit of the heirs,
executors and administrators of that person.

     We carry directors' and officers' liability insurance.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

     During the past three years, we have issued unregistered securities to a
limited number of persons as described below:


          In April 1997, we raised approximately $9.0 million from the sale of
     an aggregate of 8,093,022 shares of Series D Preferred Stock to 66
     investors in an offering at $1.10 per share. We paid Robertson, Stephens &
     Company LLC $145,096.98 and issued an additional 81,027 shares of Series D
     Preferred Stock to Robertson, Stephens & Company LLC as consideration for
     its services as a placement agent in connection with the Series D offering.



          In the second half of 1997, we raised approximately $15.4 million from
     the sale of an aggregate of 431,327,408 shares of Series E Preferred Stock
     to 49 investors in an offering at $.035619838954 per share. We paid
     BankAmerica Robertson Stephens a placement agent fee in the amount of
     $32,040 as consideration for its services as a placement agent in
     connection with the Series E offering.



          In late 1998, we raised approximately $15.7 million from the sale of
     an aggregate of 283,471,155 shares of Series F Preferred Stock to 31
     investors in an offering at $0.05526523774 per share.


          On June 11, 1999 and August 2, 1999, we raised approximately $6.0
     million and $338,187, respectively, from the sale of convertible promissory
     notes along with warrants to purchase shares of our common stock to certain
     of our existing stockholders. These loans were evidenced by convertible
     promissory notes and $6.3 million of the notes automatically converted into
     shares of Series G Preferred Stock upon the closing of the offering of
     Series G Preferred Stock.

          In September 1999, we raised $30 million from the sale of an aggregate
     of 230,769,231 shares of Series G Preferred Stock to 45 investors in an
     offering at $0.13 per share.


          From January 1, 1996 through October 26, 1999, (the most recent
     practicable date), we granted stock options to purchase an aggregate of
     148,517,725 shares of our common stock at prices ranging from $.066 to
     $10.62 per share to employees, consultants and directors (net of options
     forfeited for failure to exercise prior to expiration date).



          From January 1, 1996 through October 26, 1999, (the most recent
     practicable date), we issued and sold an aggregate of 18,499,659 shares of
     our common stock to employees, consultants and directors for aggregate
     consideration of $225,012 pursuant to exercise of stock options and grant
     of stock awards.


     For additional information concerning these sales of unregistered
securities, see "Certain Transactions" in the form of prospectus included in
this registration statement.

     Except where otherwise provided above, none of these unregistered sales
transactions involved any underwriters, underwriting discounts or commissions,
or any public offering. We believe that each transaction was exempt from the
registration requirements of the Securities Act by virtue of Section 4(2) of the
Securities Act, Regulation D promulgated under Section 4(2) or Rule 701 pursuant
to compensatory benefit plans and contracts relating to compensation as provided
under Rule 701. The recipients in these transactions represented their intention
to acquire the securities for investment only and not with a view to or for sale
in connection with any distribution of the securities, and appropriate legends

with us, to information about us.

ITEM 17.  UNDERTAKINGS.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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

                                      II-3
<PAGE>   99

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 that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of Prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and this offering of such securities at
     that time shall be deemed to be the initial bona fide offering thereof.

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

("Qualified Public Offering"), the aggregate number of shares of capital stock
which the Corporation shall have authority to issue shall be 2,745,772,207
shares, of which 11,940,301 shares shall be Series A Voting Convertible

Law of the State of Delaware (the "Effective Time"), each 66.38 shares of Common
Stock, par value $.001 per share, of the Corporation ("Old Common Stock") issued
and outstanding immediately prior to the Effective Time shall be automatically
reclassified as and converted into one (1) share of Common Stock, par value
$.001 per share, of the Corporation ("New Common Stock"). Notwithstanding the
immediately preceding sentence, no fractional shares of New Common Stock shall
be issued to the holders of record of Old Common Stock in connection with the
foregoing reclassification of shares of Old Common Stock. In lieu thereof, the
Corporation shall deliver to any stockholder that would otherwise receive a
fractional share one additional share. Each stock certificate that, immediately
prior to the Effective Time, represented shares of Old Common Stock shall, from
and after the Effective Time, automatically and without the necessity of
presenting the same for exchange, represent that number of whole shares of New

number of whole shares of New Common Stock into which the Shares of Old Common
Stock represented by such certificate shall have been reclassified.

IV.B. and Article IV.C. shall expire, the Company shall no longer have the
authority to issue shares of Company Preferred Stock and the aggregate number of
shares of capital stock which the Corporation shall thereafter have authority to
issue is

60,000,000 shares, consisting of two classes of capital stock:

              (a)    50,000,000 shares of common stock, par value $.001 per
share (the "Post-IPO Common Shares");

              (b)    10,000,000 shares of preferred stock, par value $.001 per
share (the "Post-IPO Preferred Shares").

       For purposes of this Sixth Amended and Restated Certificate of
Incorporation, "Common Stock" is not part of and is distinct from the "Post-IPO
Common Shares" and "Company Preferred Stock" is not part of and is distinct from
the "Post-IPO Preferred Shares."

       B.     RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS OF SERIES A
PREFERRED STOCK, SERIES B PREFERRED STOCK, SERIES C PREFERRED STOCK, SERIES D
PREFERRED STOCK AND COMMON STOCK. The rights, preferences, privileges and
restrictions granted to and imposed upon the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Common
Stock are set forth in this Division B and are subject to the provisions of
Article IV. C.

       1.     DIVIDENDS.

       (a)    Holders of Series A, Series B, Series C and Series D Preferred
Stock. The holders of shares of Series A Preferred Stock shall be entitled to
receive cumulative cash dividends at the rate of $.0594 per share per annum, out
of the Corporation's surplus or, in case there shall be no surplus, out of its
net profits for the fiscal year in which the dividend is declared and/or the
preceding fiscal year, or assets legally available for the payment thereof. The
holders of shares of Series B Preferred Stock shall be entitled to receive
cumulative cash dividends, at the rate of $0.2930291 per share per annum, out of
the Corporation's surplus or, in case there shall be no surplus, out of its net
profits for the fiscal year in which the dividend is declared and/or the
preceding fiscal year, or assets legally available for the payment thereof. The
holders of shares of Series C Preferred Stock shall be entitled to receive
cumulative cash dividends at the rate of $.36 per share per annum, out of the
Corporation's surplus or, in case there shall be no surplus, out of its net
profits for the fiscal year in which the dividend is declared and/or the
preceding fiscal year, or assets legally available for the payment thereof. The
holders of shares of Series D Preferred Stock shall be entitled to receive
cumulative cash dividends at the rate of $.0666 per share per annum, out of the
Corporation's surplus or, in case there shall be no surplus, out of its net
profits for the fiscal year in which the dividend is declared and/or the
preceding fiscal year, or assets legally available for the payment thereof. Such
dividends shall be payable quarterly on the fifteenth (15th) day of December,
March, July and September in each year, to such stockholders of record on the
fortieth (40th) day preceding each such dividend payment date. Dividends on the
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock,
and Series D Preferred Stock shall accrue, from the date of initial issuance
until paid, and be deemed to accrue from day to day whether or not earned or
declared and shall be cumulative. The holders of sixty percent (60%) of the
aggregate Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock (the "Collective A, B and C Preferred Stock") then outstanding,
voting


                                     - 7 -
<PAGE>   8


separately as a single class on the basis of one vote for each share of
Collective A, B and C Preferred Stock outstanding, may waive in writing the
payment of dividends on all shares of Collective A, B and C Preferred Stock then
outstanding at any time or times so long as any of the Collective A, B and C
Preferred Stock remains outstanding. Arrearages in the payment of dividends
shall not bear interest. The holders of sixty percent (60%) of the aggregate
Series D Preferred Stock then outstanding may waive in writing the payment of
dividends on all shares of Series D Preferred Stock then outstanding at any time
or times so long as any of the Series D Preferred Stock remains outstanding.

So long as any shares of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock or Series D Preferred Stock (the "Collective Preferred
Stock") remain outstanding, no dividend whatsoever shall be paid or declared on
any Common Stock or any junior stock (which term as used herein shall mean the
Common Stock and any other class of stock of the Corporation hereafter
authorized ranking junior to the Collective Preferred Stock as to dividends),
nor shall any distribution be made on any junior stock, other than a dividend
payable in junior stock, nor shall any shares of any junior stock be acquired
for consideration by the Corporation (other than purchases or redemptions
pursuant to or in accordance with employee stock control, subscription or option
agreements entered into between the Corporation and its or its subsidiaries'
directors, officers and employees prior to the date on which a share of Series F
Preferred Stock is first issued (the "Original Series F Issue Date") and other
than the repurchase, redemption or other retirement of debentures or other debt
securities that are convertible or exchangeable into any of the Junior
Securities or Parity Securities) unless all dividends accrued, whether or not
declared, on the Collective Preferred Stock for all past quarter-yearly dividend
periods and then in arrears shall have been paid and the full dividends due
thereon for the then current quarter-yearly dividend period shall have been paid
or shall have been declared and a sum sufficient for the payment thereof set
apart.

No dividend shall be declared or paid on any Series A Preferred Stock, Series B
Preferred Stock or Series C Preferred Stock, or on the Corporation's Series A
Non-Voting Redeemable Preferred Stock, previously authorized and outstanding and
exchanged for Series A Preferred Stock, unless simultaneously with such payment
there is paid to holders of Series D Preferred Stock all of the cumulative
dividends accrued, whether or not declared, and then in arrears on the
Corporation's Series D Preferred Stock; and provided that no dividend shall be
declared or paid for any quarter-yearly period on any share of Series B
Preferred Stock or Series C Preferred Stock unless simultaneously with such
payment there is paid to holders of Series A Preferred Stock all of the
cumulative dividends accrued, whether or not declared, and then in arrears on
the Corporation's Series A Non-Voting Redeemable Preferred Stock, previously
authorized and outstanding and exchanged for shares of Series A Preferred Stock,
as well as all of the cumulative dividends accrued, whether or not declared, on
the Series A Preferred Stock prior to the issuance of the share of Series B
Preferred Stock or Series C Preferred Stock with respect to which the dividend
is proposed to be declared or paid and then in arrears; and provided further
that, no dividend shall be declared or paid for any quarter-yearly period on any
share of Series C Preferred Stock unless simultaneously with such payment there
is paid to the holders of Series B Preferred Stock all of the cumulative
dividends accrued, whether or not declared, on the Series B Preferred Stock
prior to the issuance of the share of Series C Preferred Stock with respect to
which the dividend is


                                     - 8 -
<PAGE>   9


proposed to be declared or paid and then in arrears.

Except as otherwise specified in this Article IV.B.1(a), the Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred
Stock rank on a parity with each other with respect to dividend rights.

No dividend shall be declared or paid for any quarter-yearly period on any stock
of the Corporation ranking equally with the Collective Preferred Stock as to
dividends unless simultaneously with such payment there is paid (i) all of the
cumulative dividends accrued, whether or not declared, on the Collective
Preferred Stock and then in arrears, and (ii) a percentage of the quarter-yearly
dividend payable on the Collective Preferred Stock for such quarter-yearly
period equal to the percentage of the quarter-yearly dividend on such other
stock which is then to be paid.

Subject to the foregoing provisions, and not otherwise, such dividends (payable
in cash, stock or otherwise) as may be determined by the Board of Directors of
the Corporation (the "Board of Directors") may be declared and paid on any
junior stock from time to time out of the remaining funds of the Corporation
legally available for the payment of dividends, and the Collective Preferred
Stock shall not be entitled to participate in any such dividends, whether
payable in cash, stock or otherwise.

       (b)    Holders of Common Stock. Subject to the provisions of Article
IV.B.1(a) hereof, the holders of shares of Common Stock shall be entitled to
receive, when and as declared by the Board of Directors, such dividends out of
the Corporation's surplus or, in case there shall be no surplus, out of its net
profits for the fiscal year in which the dividend is declared and/or the
preceding fiscal year, or assets legally available for the payment thereof, as
may be declared from time to time by the Board of Directors.

       2.     LIQUIDATION.

       (a)    Preference. In the event of any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the holders of
the Collective Preferred Stock shall be entitled to receive in cash out of the
assets of the Corporation, before any distribution or payment shall be made to
the holders of any junior stock, as follows:

              (i)    an amount per share equal to $1.10 for each outstanding
share of Series D Preferred Stock, plus any accrued but unpaid dividends,
whether or not declared, on such share to holders of Series D Preferred Stock;

              (ii)   an amount per share equal to $.99 for each outstanding
share of Series A Preferred Stock, plus any accrued but unpaid dividends,
whether or not declared, on such share to holders of Series A Preferred Stock;

              (iii)  an amount per share equal to $4.883818833 for each
outstanding share of Series B Preferred Stock, plus any accrued but unpaid
dividends, whether or not declared, on


                                     - 9 -
<PAGE>   10


such share to holders of Series B Preferred Stock; and

              (iv)   an amount per share equal to $6.00 for each outstanding
share of Series C Preferred Stock, plus any accrued but unpaid dividends,
whether or not declared, on such share to holders of Series C Preferred Stock.

If upon the occurrence of such event, the assets and funds of the Corporation
shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amounts, then the entire assets and funds of the
Corporation legally available for distribution shall be distributed among the
holders of the Collective Preferred Stock in respect of accrued but unpaid
dividends in accordance with the priorities established in the third paragraph
of Article IV.B.1(a) hereof and any remaining assets and funds legally available
for distribution shall be distributed first to the holders of the Series D
Preferred Stock in an amount equal to $1.10 for each outstanding share of Series
D Preferred Stock (pro rated among them on the basis of outstanding shares of
Series D Preferred Stock) and any excess among the holders of the Collective A,
B and C Preferred Stock as follows:

              (i)    an amount per share equal to $.99 multiplied by the
"Distribution Fraction" (as defined below) for each outstanding share of Series
A Preferred Stock to holders of Series A Preferred Stock;

              (ii)   an amount per share equal to $4.883818833 multiplied by the
"Distribution Fraction" for each outstanding share of Series B Preferred Stock;
and

              (iii)  an amount per share equal to $6.00 multiplied by the
"Distribution Fraction" for each outstanding share of Series C Preferred Stock.

       For purposes of the foregoing calculations, "Distribution Fraction" shall
be a fraction determined by dividing (A) the amount of such remaining assets and
funds legally available for distribution by (B) the sum of (I) $.99 multiplied
by the number of shares of Series A Preferred Stock then outstanding, plus (II)
$4.883818833 multiplied by the number of shares of Series B Preferred Stock then
outstanding, plus (III) $6.00 multiplied by the number of shares of Series C
Preferred Stock then outstanding.

       (b)    Consolidation, Merger, etc.

              (i)    For purposes of this Section 2, a Change of Control (as
defined in Article IV.B.2(b)(ii) below) shall, at the option of each holder of
Collective Preferred Stock, upon written notice to the Corporation prior to the
closing of the transaction that constitutes a Change of Control, be treated as a
liquidation, dissolution or winding up of the Corporation with respect to such
holder and shall entitle the electing holders of Collective Preferred Stock to
receive, at the closing of the transaction that constitutes a Change of Control,
in cash, securities or other property (valued as provided in Article
IV.B.2(b)(iii) below), amounts as specified in Article IV.B.2(a) above;
provided, however, that when such payments are made as a result of a Change of
Control that is treated as a liquidation, dissolution, or winding up of the
Corporation, the


                                     - 10 -
<PAGE>   11


payment to be made pursuant to this Article IV.B.2(b) shall be made only upon
surrender of the certificate or certificates for the shares of Collective
Preferred Stock with respect to which such payment is to be made, and, from and
after the date that the certificate or certificates for such shares are required
to be surrendered (whether or not such certificate or certificates are
surrendered on such date), all rights (other than the right to receive payment
as provided in this Article IV.B.2(b) upon surrender of such certificate or
certificates) with respect to such shares shall terminate, and such shares be
deemed to be canceled and retired. Notwithstanding the foregoing, a Change of
Control shall not be treated as a liquidation, dissolution or winding up of the
Corporation with respect to any holder of the Collective Preferred Stock if (x)
both (i) the holders of sixty percent (60%) of the Series D Preferred Stock then
outstanding, and (ii) the holders of sixty percent (60%) of the Collective A, B
and C Preferred Stock then outstanding, each voting separately as a single class
on the basis of one vote for each share of Series D Preferred Stock then
outstanding or Collective A, B and C Preferred Stock then outstanding, as
applicable, waive in writing the provisions of the preceding sentence prior to
definitive authorization by the Corporation's Board of Directors of such
consolidation, merger or sale of assets or prior to the order of such court or
administrative body requiring such reorganization or (y) such Change of Control
has not been treated as a liquidation, dissolution or winding up of the
Corporation with respect to any holder of Series E Preferred Stock, Series F
Preferred Stock or Series G Preferred Stock.

                     (ii)   "Change of Control" means (x) the sale, lease,
conveyance or other disposition of all or substantially all of the Corporation's
assets as an entirety or substantially as an entirety to any person or "group"
(within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) in one or a series of transactions, provided
that a transaction where the holders of all classes of voting stock of the
Corporation immediately prior to such transaction own, directly or indirectly,
more than 50% of the aggregate voting power of all classes of voting stock of
such person or group immediately after such transaction shall not be a Change of
Control; or (y) any transaction or series of transactions (as a result of a
tender offer, merger, consolidation or otherwise, but not as a result of the
issuance of Series E Preferred Stock or of a Qualified Public Offering, as
defined in Article IV.B.3(l)(i)) that results in, or that is in connection with,
any person, including a "group" (within the meaning of Section 13(d)(3) of the
Exchange Act) that includes such person, acquiring "beneficial ownership" (as
defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% or
more of the aggregate voting power of all classes of voting stock of the
Corporation or any person that possesses "beneficial ownership" (as defined in
Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% or more of
the aggregate voting power of all classes of voting stock of the Corporation.

                     (iii)  Whenever the distribution provided for in this
Article IV.B.2 shall be payable in securities or property other than cash, the
value of such distribution shall be the fair market value of such securities or
other property as determined in good faith by the Board of Directors of the
Corporation.

       (c)    Distributions to Holders of Common Stock. After the payment of all
preferential amounts required to be paid to the holders of shares of Collective
Preferred Stock and the


                                     - 11 -
<PAGE>   12


"Senior Preferred Stock" (as defined in Article IV.C.1 hereto) upon the
liquidation, dissolution or winding up of the Corporation, the holders of shares
of Common Stock then outstanding shall be entitled to receive the remaining
assets and funds of the Corporation available for distribution to its
stockholders, pro rata based upon the number of shares of Common Stock held by
each such holder.

       (d)    Waiver of Liquidation Preference. The holders of sixty percent
(60%) of the Series D Preferred Stock then outstanding may waive in writing the
liquidation preference set forth in Article IV.B.2(a) as to the Series D
Preferred Stock. The holders of sixty percent (60%) of the Collective A, B and C
Preferred Stock then outstanding, voting separately as a single class on the
basis of one vote for each share of Collective A, B and C Preferred Stock
outstanding, may waive in writing the liquidation preference set forth in
Article IV.B.2(a) as to the Collective A, B and C Preferred Stock.

       3.     CONVERSION. The holders of any of the shares of Collective
Preferred Stock shall have conversion rights respectively as follows (the
"Conversion Rights"):

       (a)    Right to Convert.

              (i)    Series A Preferred Stock. Each share of Series A Preferred
Stock shall be convertible, at the option of the holder thereof, at any time and
from time to time, into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing $1.00 by the Series A Conversion Price
(as defined below) in effect at the time of conversion. The conversion price at
which shares of Common Stock shall be deliverable upon conversion of Series A
Preferred Stock without the payment of additional consideration by the holder
thereof (the "Series A Conversion Price") shall be $4.020052210 per share. Such
Series A Conversion Price, and the rate at which shares of Series A Preferred
Stock may be converted into shares of Common Stock, shall be subject to
adjustment as provided below.

              (ii)   Series B Preferred Stock. Each share of Series B Preferred
Stock shall be convertible, at the option of the holder thereof, at any time and
from time to time, into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing $4.883818833 by the Series B
Conversion Price (as defined below) in effect at the time of conversion. The
conversion price at which shares of Common Stock shall be deliverable upon
conversion of Series B Preferred Stock without the payment of additional
consideration by the holder thereof (the "Series B Conversion Price") shall be
$4.020052210 per share. Such Series B Conversion Price, and the rate at which
shares of Series B Preferred Stock may be converted into shares of Common Stock,
shall be subject to adjustment as provided below.

              (iii)  Series C Preferred Stock. Each share of Series C Preferred
Stock shall be convertible, at the option of the holder thereof, at any time and
from time to time, into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing $6.00 by the Series C Conversion Price
(as defined below) in effect at the time of conversion. The conversion price at
which shares of Common Stock shall be deliverable upon conversion of Series C
Preferred Stock without the payment of additional consideration by the holder
thereof


                                     - 12 -
<PAGE>   13


(the "Series C Conversion Price") shall be $4.881432585 per share. Such Series C
Conversion Price, and the rate at which shares of Series C Preferred Stock may
be converted into shares of Common Stock, shall be subject to adjustment as
provided below.

              (iv)   Series D Preferred Stock. Each share of Series D Preferred
Stock shall be convertible, at the option of the holder thereof, at any time and
from time to time, into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing $1.10 by the Series D Conversion Price
(as defined below) in effect at the time of conversion. The conversion price at
which shares of Common Stock shall be deliverable upon conversion of Series D
Preferred Stock without the payment of additional consideration by the holder
thereof (the "Series D Conversion Price") shall be $1.10 per share. Such Series
D Conversion Price, and the rate at which shares of Series D Preferred Stock may
be converted into shares of Common Stock, shall be subject to adjustment as
provided below.

Each of the "Series A Conversion Price," the "Series B Conversion Price," the
"Series C Conversion Price" and the "Series D Conversion Price" may be referred
to herein as the "Conversion Price," but the Conversion Price applicable to
Series A Preferred Stock shall only be the "Series A Conversion Price," the
Conversion Price applicable to Series B Preferred Stock shall only be the
"Series B Conversion Price", the Conversion Price applicable to Series C
Preferred Stock shall only be the "Series C Conversion Price," and the
Conversion Price applicable to Series D Preferred Stock shall only be the
"Series D Conversion Price."

Subject to Article IV.B.3 (l)(i), in the event that at the time of the
conversion of a holder's Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, or Series D Preferred Stock there are accrued but
unpaid cash dividends, whether or not declared, on such Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock, or Series D Preferred
Stock and provided no shares of Series E Preferred Stock, Series F Preferred
Stock or Series G Preferred Stock are or remain outstanding, such cash dividend
payable to a holder of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, or Series D Preferred Stock pursuant to Article
IV.B.1(a) hereof shall be paid and distributed to such holder of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or Series D
Preferred Stock immediately prior to the conversion of such holder's Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or Series D
Preferred Stock; provided that if a holder intends to convert only a portion of
its Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock, or Series D Preferred Stock, the cash dividend payable to such holder
immediately prior to such conversion shall be that dollar amount which is
proportionate to the number of shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, or Series D Preferred Stock which
such holder intends to convert.

If pursuant to and in accordance with Article IV.B.1(a) and this Article
IV.B.3(a)(iv), the Corporation cannot distribute all or a portion of such cash
dividend ("Dividend Payment Obligation") immediately prior to such conversion
then the Corporation shall distribute the balance of such Dividend Payment
Obligation as soon as assets or funds are available for such distribution under
and in accordance with Article IV.B.1(a); provided that, notwithstanding
anything contained herein to the contrary, no Dividend Payment Obligation may be
paid by the


                                     - 13 -
<PAGE>   14


Corporation so long as shares of Series E Preferred Stock, Series F Preferred
Stock, or Series G Preferred Stock are or remain outstanding.

       (b)    Mechanics of Conversion.

              (i)    In order for a holder of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, or Series D Preferred Stock to
convert shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, or Series D Preferred Stock into shares of Common Stock, such
holder shall surrender the certificate or certificates for such shares of Series
A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or Series
D Preferred Stock at the office of the transfer agent for the Collective
Preferred Stock (or at the principal office of the Corporation if the
Corporation serves as its own transfer agent), together with written notice that
such holder elects to convert all or any number of the shares of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or Series D
Preferred Stock represented by such certificate or certificates. Such notice
shall state such holder's name or the names of the nominees in which such holder
wishes the certificate or certificates for shares of Common Stock to be issued.
If required by the Corporation, certificates surrendered for conversion shall be
endorsed or accompanied by a written instrument or instruments of transfer, in
form satisfactory to the Corporation, duly executed by the registered holder or
his, her or its attorney duly authorized in writing. The date of receipt of such
certificates and notice by the transfer agent (or by the Corporation if the
Corporation serves as its own transfer agent) shall be the conversion date
("Conversion Date"). The Corporation shall, as soon as practicable after the
Conversion Date, issue and deliver at such office to such holder of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or Series D
Preferred Stock, or to his, her or its nominees, a certificate or certificates
for the number of shares of Common Stock to which such holder shall be entitled.
No fractional shares shall be issued upon conversion of the Collective Preferred
Stock, and the number of shares of Common Stock to be issued shall be rounded up
to the nearest whole share. In determining the number of shares of Common Stock
issuable upon conversion, each holder's Collective Preferred Stock and Senior
Preferred Stock being converted on the same day shall be aggregated.

              (ii)   The Corporation shall at all times when the Collective
Preferred Stock shall be outstanding, reserve and keep available out of its
authorized but unissued stock, for the purpose of effecting the conversion of
the Collective Preferred Stock, such number of its duly authorized shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding shares of Collective Preferred Stock. Before taking any
action which would cause an adjustment reducing the Conversion Price below the
then par value of the shares of Common Stock issuable upon conversion of the
Collective Preferred Stock, the Corporation will take any corporate action which
may, in the opinion of its counsel, be necessary in order that the Corporation
may validly and legally issue fully paid and nonassessable shares of Common
Stock at such adjusted Conversion Price.

              (iii)  On the Conversion Date, all shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock, or Series D Preferred
Stock which shall have been surrendered for conversion as herein provided shall
no longer be deemed to be outstanding and


                                     - 14 -
<PAGE>   15


all rights with respect to such shares, including the rights, if any, to receive
notices and to vote such Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, or Series D Preferred Stock shall immediately cease
and terminate on the Conversion Date, except only the right of the holders
thereof to receive shares of Common Stock in exchange therefor.

              (iv)   If the conversion is in connection with an underwritten
offering of securities registered pursuant to the Securities Act of 1933, as
amended, which is not a Qualified Public Offering as defined in Article
IV.B.3(l)(i) hereof, the conversion may, at the option of any holder tendering
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or
Series D Preferred Stock for conversion, be conditioned upon the closing with
the underwriter of the sale of securities pursuant to such offering, in which
event the person(s) entitled to receive the Common Stock issuable upon such
conversion of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, or Series D Preferred Stock shall not be deemed to have
converted such Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, or Series D Preferred Stock until immediately prior to the
closing of the sale of securities.

       (c)    Adjustment for Stock Splits and Combinations. If the Corporation
shall at any time or from time to time effect a subdivision of the outstanding
Common Stock, each Conversion Price then in effect immediately before that
subdivision shall be proportionately decreased. If the Corporation shall at any
time or from time to time combine the outstanding shares of Common Stock, each
Conversion Price then in effect immediately before the combination shall be
proportionately increased. Any adjustment under this subsection shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

       (d)    Adjustment for Certain Dividends and Distributions. In the event
the Corporation at any time, or from time to time shall make or issue, or fix a
record date for the determination of holders of any Common Stock entitled to
receive a dividend or other distribution payable in additional shares of Common
Stock, then and in each such event each Conversion Price then in effect shall be
decreased as of the time of such distribution or, in the event such a record
date shall have been fixed, as of the close of business on such record date, by
multiplying the Conversion Price then in effect by a fraction:

              (x)    the numerator of which shall be the total number of shares
       of Common Stock issued and outstanding immediately prior to the time of
       such issuance or the close of business on such record date, and

              (y)    the denominator of which shall be the total number of
       shares of Common Stock issued and outstanding immediately prior to the
       time such dividend or other distribution is made or issued or the close
       of business on such record date, as applicable, plus the number of shares
       of Common Stock issuable in payment of such dividend or distribution;

provided, however, if such record date shall have been fixed and such dividend
is not fully paid or if such distribution is not fully made on the date fixed
therefor, the Conversion Price shall be


                                     - 15 -
<PAGE>   16


recomputed accordingly as of the close of business on such record date and
thereafter the Conversion Price shall be adjusted pursuant to this subsection as
of the time of actual payment of such dividends or distributions.

       (e)    Adjustments for Other Dividends and Distributions. In the event
the Corporation at any time or from time to time shall make or issue, or fix a
record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in securities of the
Corporation other than shares of Common Stock, then and in each such event
provision shall be made so that the holders of Series A Preferred Stock, Series
B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall
receive upon conversion thereof in addition to the number of shares of Common
Stock receivable thereupon, the amount of securities of the Corporation that
they would have received had their Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock, or Series D Preferred Stock been converted into
Common Stock on the date of such event and had thereafter, during the period
from the date of such event to and including the Conversion Date, retained such
securities receivable by them as aforesaid during such period giving application
to all adjustments called for during such period, under this paragraph (e) with
respect to the rights of the holders of Collective Preferred Stock.

       (f)    Adjustment for Reclassification, Exchange or Substitution. If the
Common Stock issuable upon the conversion of the Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock, or Series D Preferred Stock
shall be changed into the same or a different number of shares of any class or
classes of stock, whether by capital reorganization, reclassification, or
otherwise (other than a subdivision or combination of shares or stock dividend
provided for above, or a reorganization, merger, consolidation, or sale of
assets provided for below), then and in each such event the holder of each such
share of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock, or Series D Preferred Stock shall have the right thereafter to convert
such share into the kind and amount of shares of stock and other securities and
property receivable upon such reorganization, reclassification, or other change,
by holders of the number of shares of Common Stock into which such shares of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or
Series D Preferred Stock might have been converted immediately prior to such
reorganization, reclassification, or other change, all subject to further
adjustment as provided herein.

       (g)    Adjustment for Merger or Reorganization, etc. In case of any
consolidation or merger of the Corporation with or into another corporation
(other than a Change of Control (as defined in Article IV.B.2(b)(ii) above)
which is treated as a liquidation pursuant to Article IV.B.2(b) by the holders
of a majority of the Collective Preferred Stock then outstanding), the
authorized capital of the surviving or resulting corporation (referred to herein
as the "surviving corporation") shall include provision for a class or classes
of senior preferred stock having rights, preferences and limitations
substantially economically equivalent to the Series A Preferred Stock, the
Series B Preferred Stock, the Series C Preferred Stock and the Series D
Preferred Stock with respect to the capital structure of the Corporation
immediately prior to such consolidation or merger, including provision for each
holder of each share of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock, or Series D Preferred Stock to receive


                                     - 16 -
<PAGE>   17


the preferred stock of the surviving corporation which corresponds to such
series on a substantially economically equivalent basis and which shall
thereafter be convertible into the kind and amount of shares of stock or other
securities of the surviving corporation or other property to which a holder of
the number of shares of Common Stock of the Corporation deliverable upon
conversion of such Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, or Series D Preferred Stock as the case may be, would have been
entitled upon such consolidation or merger; and, in such case, appropriate
adjustment (as determined in good faith by the Board of Directors) shall be made
in the application of the provisions set forth in this Article IV.B.3 with
respect to the rights and interest thereafter of the holders of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock to the end that the provisions set forth in this Article IV.B.3
(including provisions with respect to changes in and other adjustments of the
Conversion Price) shall thereafter be applicable, as nearly as reasonably may
be, in relation to any shares of stock or other securities of the surviving
corporation or other property thereafter deliverable upon the conversion of the
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock.

       (h)    No Impairment. Except as permitted by applicable law and this
Certificate of Incorporation, including this Article IV.B, the Corporation will
not, by amendment of its Certificate of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Article IV.B.3 and in the taking of
all such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of Collective Preferred Stock against
impairment.

       (i)    Certificate as to Adjustments. Upon the occurrence of each
adjustment of the Conversion Price pursuant to this Article IV.B.3, the
Corporation at its expense shall promptly compute such adjustment in accordance
with the terms hereof and furnish to each holder of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock, or Series D Preferred Stock,
as applicable, a certificate setting forth such adjustment and showing in detail
the facts upon which such adjustment is based. The Corporation shall, upon the
written request at any time of any holder of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, or Series D Preferred Stock furnish
or cause to be furnished to such holder a similar certificate setting forth (i)
such adjustments, (ii) the Conversion Price then in effect, and (iii) the number
of shares of Common Stock and the amount, if any, of other property which then
would be received upon the conversion of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, or Series D Preferred Stock.

       (j)    Notice of Record Date. In the event:

              (i)    that the Corporation declares a dividend (or any other
distribution) on its Common Stock payable in Common Stock or other securities of
the Corporation;

              (ii)   that the Corporation subdivides or combines its outstanding
shares of


                                     - 17 -
<PAGE>   18


Common Stock;

              (iii)  of any reclassification of the Common Stock of the
Corporation (other than a subdivision or combination of its outstanding shares
of Common Stock or a stock dividend or stock distribution thereon), or of any
consolidation or merger of the Corporation into or with another corporation, or
of the sale of all or substantially all of the assets of the Corporation; or

              (iv)   of the involuntary or voluntary dissolution, liquidation or
winding up of the Corporation;

then the Corporation shall cause to be filed at its principal office or at the
office of the transfer agent of the Collective Preferred Stock, and shall cause
to be mailed to the holders of Collective Preferred Stock at their last
addresses as shown on the records of the Corporation or such transfer agent, at
least ten (10) days prior to the record date specified in (A) below or twenty
(20) days before the date specified in (B) below, a notice stating:

                     (A)    the record date of such dividend, distribution,
subdivision or combination, or, if a record is not to be taken, the date as of
which the holders of Common Stock of record to be entitled to such dividend,
distribution, subdivision or combination are to be determined, or

                     (B)    the date on which such reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up is expected
to become effective, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their shares of Common
Stock for securities or other property deliverable upon such reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up.

       (k)    Notices. Any notice required by the provisions of this Article
IV.B.3 to be given to the holders of shares of Collective Preferred Stock shall
be deemed given if deposited in the United States mail, first class, postage
prepaid, and addressed to each holder of record at its address appearing on the
books of the Corporation.

       (l)    Mandatory Conversion

              (i)    Mandatory Conversion Event. All holders of shares of Series
A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series
D Preferred Stock then outstanding shall convert their shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock into shares of Common Stock, at the then effective Conversion
Price pursuant to this Article IV.B.3, upon the closing of a Qualified Public
Offering.

Notwithstanding any provision to the contrary contained herein, (x) in the event
that there are accrued but unpaid cash dividends or Dividend Payment Obligations
at the date of the closing of a Qualified Public Offering, all such accrued but
unpaid cash dividends and Dividend Payment


                                     - 18 -
<PAGE>   19


Obligations payable to the holders of Collective Preferred Stock shall be
canceled, and no holder or former holder of Collective Preferred Stock shall
have any further right or interest therein or (y) in the event of voluntary
conversion by a holder of any Collective Preferred Stock at a time when the
Corporation is contemplating an initial public offering, the Corporation may, at
its option, defer payment of any dividends otherwise payable upon such
conversion for up to 180 days and if a Qualified Public Offering is closed
within such 180 day period, all of such accrued but unpaid cash dividends
payable to such holders of Collective Preferred Stock shall be canceled and no
such holder of Collective Preferred Stock shall have any further right or
interest therein.

              (ii)   Procedure for Mandatory Conversion. Upon a mandatory
conversion pursuant to Article IV.B.3(l)(i), the outstanding shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, and Series
D Preferred Stock will be automatically converted into shares of Common Stock
without any further action by the holders of such shares and whether or not the
certificates representing such shares are surrendered for conversion to the
Corporation or the transfer agent for the Collective Preferred Stock. On the
date of mandatory conversion, all rights with respect to the Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock, or Series D Preferred
Stock so converted, including the rights, if any, to receive notices and vote,
will terminate, except for the rights of the holders thereof, upon surrender of
their certificate or certificates therefor, to receive certificates for the
number of shares of Common Stock into which such Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock, or Series D Preferred Stock
has been converted (as rounded with respect to any fraction of a share as
provided in Article IV.B.3(b)). If so required by the Corporation, certificates
surrendered for conversion shall be endorsed or accompanied by written
instrument or instruments of transfer, in form satisfactory to the Corporation,
duly authorized in writing. As soon as practicable after the date of such
mandatory conversion and the surrender of the certificate or certificates of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, or
Series D Preferred Stock, the Corporation shall cause to be issued and delivered
to such holder, or on his or its written order, a certificate or certificates
for the number of full shares of Common Stock issuable on such conversion in
accordance with the provisions hereof as rounded as provided in Section 3(b) in
respect of any fraction of a share of Common Stock otherwise issuable upon such
conversion.

       (m)    Retirement and Cancellation of Shares. All certificates evidencing
shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock, or Series D Preferred Stock which are required to be surrendered for
conversion in accordance with the provisions hereof shall, from and after the
date such certificates are so required to be surrendered, be deemed to have been
retired and canceled and the shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock
represented thereby converted into Common Stock for all purposes,
notwithstanding the failure of the holder or holders thereof to surrender such
certificates on or prior to such date.

       5.     PRE-EMPTIVE RIGHTS.

       (a)    Right to Purchase. The holders of any Collective Preferred Stock
(hereinafter referred to in this Article IV.B.5 collectively as the "Holders"
and individually as a "Holder") shall have the pre-emptive right to purchase, on
a pro rata basis, all or any part of New Securities (as hereinafter defined)
which the Corporation may, from time to time, propose to issue and sell, subject
to the terms and conditions set forth below. The pro rata share of each Holder
of Series A Preferred Stock, for purposes of this pre-emptive right to purchase,
shall be determined by dividing (x) the total number of shares of Common Stock
which are owned by such Holder plus the total number of shares of Common Stock
issuable upon conversion of Series A Preferred Stock owned by such Holder of
Series A Preferred Stock, by (y) the total number of shares of Common Stock then
outstanding plus the total number of shares of Common Stock issuable upon
conversion of all then outstanding Company Preferred Stock. The pro rata share
of each Holder of Series B Preferred Stock, for purposes of this pre-emptive
right to purchase, shall be determined by dividing (x) the total number of
shares of Common Stock which are owned by such Holder plus, the total number of
shares of Common Stock issuable upon conversion of Series B Preferred Stock
owned by such Holder of Series B Preferred Stock, by (y) the total number of
shares of Common Stock then outstanding plus the total number of shares of
Common Stock issuable upon conversion of all then outstanding Company Preferred
Stock. The pro rata share of each Holder of Series C Preferred Stock, for
purposes of this pre-emptive right to purchase, shall be determined by dividing
(x) the total number of shares of Common Stock which are owned by such Holder
plus the total number of shares of Common Stock issuable upon conversion of
Series C Preferred Stock owned by such Holder of Series C Preferred Stock, by
(y) the total number of shares of Common Stock then outstanding plus the total
number of shares of Common Stock issuable upon conversion of all then
outstanding Company Preferred Stock. The pro rata share of each Holder of Series
D Preferred Stock, for purposes of this pre-emptive right to purchase, shall be
determined by dividing (x) the total number of shares of Common Stock which are
owned by such Holder plus the total number of shares of Common Stock issuable
upon conversion of Series D Preferred Stock owned by such Holder of Series D
Preferred Stock, by (y) the total number of shares of Common Stock then
outstanding plus the total number of shares of Common Stock issuable upon
conversion of all then outstanding Company Preferred Stock. All of the foregoing
notwithstanding, in the event a Holder owns shares of more than one series of
Collective Preferred Stock, the Common Stock which is owned by such Holder shall
only be counted one time in connection with any calculation of such Holder's pro
rata share.

       (b)    "New Securities". The term "New Securities" as used herein shall
mean any capital stock of the Corporation whether now or hereafter authorized,
and rights, options or warrants to purchase capital stock, and securities of any
type whatsoever which are, or may become, convertible into capital stock;
provided, however, that the term "New Securities" shall not include (i) shares
of Common Stock issuable upon conversion of any of the Preferred Stock (as
defined in Article IV.C.2 herein), (ii) shares of Series E Preferred Stock
issuable upon the exercise of the Series E Preferred Stock Warrant issued on the
Original Issue Date (as defined in Article IV.C.6(d)(iv), (iii) securities
offered to the public pursuant to a registration statement approved by the Board
of Directors and filed with the Securities and Exchange Commission for a


                                     - 24 -
<PAGE>   25


public offering and sale of securities of the Corporation, (iv) securities
issued in connection with the acquisition of another corporation by the
Corporation by merger, purchase of all or substantially all of the assets of
another corporation or other reorganization, (v) shares of Common Stock and
options therefor issued or issuable pursuant to any stock option plan or plans
or stock purchase plan or plans approved by the Board of Directors, or (vi)
securities issued as a result of any stock split, combination, reverse stock
split, stock dividend or recapitalization of the Corporation.

       (c)    Procedure. In the event the Corporation intends to issue New
Securities, it shall give each Holder written notice of such intention,
describing the type of New Securities to be issued, the price thereof and the
general terms upon which the Corporation proposes to effect such issuance. Each
such Holder shall have twenty (20) business days from the date of any such
notice to agree to purchase all or part of its pro rata share of such New
Securities, for the purchase price and upon the general terms and conditions
specified in the Corporation's notice, by giving written notice to the
Corporation stating the quantity of New Securities to be so purchased. Each
Holder shall have a right of over-allotment such that if any Holder fails to
exercise its right hereunder to purchase its total pro rata portion of New
Securities, the other Holders may purchase such portion on a pro rata basis, by
giving written notice to the Corporation within ten (10) business days from the
date that the Corporation provides written notice to the other Holders of the
amount of New Securities with respect to which such nonpurchasing Holder has
failed to exercise its rights hereunder.

       (d)    Right of Corporation. In the event any Holder or Holders fail to
exercise the foregoing pre-emptive right to purchase with respect to any New
Securities within such twenty (20) business day period (or the additional 10
business day period provided for overallotment), the Corporation may within
ninety (90) business days thereafter sell any or all of such New Securities not
agreed to be purchased by the Holders, at a price and upon general terms no more
favorable to the purchasers thereof than specified in the notice given to each
Holder pursuant to Article IV.B.5(c). In the event the Corporation has not sold
such New Securities within such ninety (90) business day period, the Corporation
shall not thereafter issue or sell any New Securities without first offering
such New Securities to the Holders in the manner provided above.

       (e)    "Holder". For purposes of this Article IV.B.5, the term "Holder"
shall include the partners, stockholders or other affiliates of a Holder, and a
Holder may apportion its pro rata share among itself and such partners,
stockholders and other affiliates in such proportion as it deems appropriate.

       (f)    Waiver. The Holders of sixty percent (60%) of the Collective
Preferred Stock then outstanding, voting separately as a single class on the
basis of one vote for each share of Collective Preferred Stock outstanding, may
waive in writing the pre-emptive right to purchase set forth in Article
IV.B.5(a) at any time or times so long as any of the Collective Preferred Stock
remains outstanding.

       (g)    Expiration. The pre-emptive rights described in this Article
IV.B.5 shall expire


                                     - 25 -

upon the closing of a Qualified Public Offering.

       C.     RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS OF SERIES E
PREFERRED STOCK, SERIES F PREFERRED STOCK, AND SERIES G PREFERRED STOCK. The
rights, preferences, privileges and restrictions granted to and imposed upon the
Series E Preferred Stock, Series F Preferred Stock, and Series G Preferred Stock
are set forth in this Article IV.C.

       1.     Designation. The Preferred Stock created and authorized hereby
shall be designated as (i) the Series E Senior Voting Convertible Preferred
Stock, par value $0.01 per share ("Series E Preferred Stock"), consisting of
568,855,000 shares, (ii) the Series F Senior Voting Convertible Preferred Stock,
par value $0.01 per share ("Series F Preferred Stock"), consisting of
361,891,142 shares, and (iii) the Series G Senior Voting Convertible Preferred
Stock, par value $0.01 per share (the "Series G Preferred Stock"), consisting of
230,769,231 shares. The Series E Preferred Stock, Series F Preferred Stock, and
Series G Preferred Stock are sometimes referred to collectively as the "Senior
Preferred Stock". The stated value ("Stated Value") (i) of the Series E
Preferred Stock shall be $0.035619838954 per share, (ii) of the Series F
Preferred Stock shall be $0.05526523774 per share, and (iii) of the Series G
Preferred Stock shall be $0.13 per share, which values do not represent a
determination by the Board of Directors of fair market value or otherwise.

       2.     Rank. The Senior Preferred Stock shall, with respect to dividend
rights (including dividends accrued on the Series E Preferred Stock and the
Series F Preferred Stock prior to the date on which shares of Series G Preferred
Stock are issued) and rights on liquidation, winding up and dissolution, rank
pari passu with each other and prior to the Common Stock and the Collective
Preferred Stock. (All equity securities of the Corporation to which the Senior
Preferred Stock ranks prior, including the Common Stock and the Collective
Preferred Stock, are collectively referred to herein as the "Junior Securities";
all equity securities of the Corporation with which the Senior Preferred Stock
ranks on a parity are collectively referred to herein as the "Parity
Securities"; all preferred stock of the Corporation, including Collective
Preferred Stock, Parity Securities and Senior Preferred Stock and any other
preferred stock of the Corporation, are collectively referred to herein as
"Preferred Stock.") The Senior Preferred Stock shall be subject to the creation
of Junior Securities and Parity Securities in accordance with the terms hereof,
but not to the creation of equity securities of the Corporation (other than
convertible debt securities) to which the Senior Preferred Stock ranks junior,
whether with respect to dividends or upon liquidation, dissolution, winding up
or otherwise.

       3.     Dividends.

       (a)    (i)    The holders of the shares of Series E Preferred Stock shall
be entitled to receive, when, as and if declared by the Board of Directors, out
of funds legally available for the payment of dividends, cumulative dividends at
the rate of $0.002849587 per share per annum. The holders of the shares of
Series F Preferred Stock shall be entitled to receive, when, as and if declared
by the Board of Directors, out of funds legally available for the payment of
dividends, cumulative dividends at the rate of $0.004421219 per share per annum.
The holders of the shares


                                     - 26 -
<PAGE>   27


of Series G Preferred Stock shall be entitled to receive, when, as and if
declared by the Board of Directors, out of funds legally available for the
payment of dividends, cumulative dividends at the rate of $0.0104 per share per
annum. Such dividends shall be payable in quarterly payments on the fifteenth
(15th) day of December, March, July and September of each year (each of such
dates being a "dividend payment date"), in preference to dividends on the Junior
Securities, provided that no dividends shall be declared or paid on the Series E
Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock, as
individual classes, unless dividends shall be declared or paid on all the Senior
Preferred Stock. Such dividends shall be paid to the holders of record at the
close of business on a record date to be set by the Board of Directors or a
committee thereof (each of such dates being a "dividend payment record date").
Each of such quarterly dividends shall be fully cumulative and shall accrue
(whether or not declared), without interest, from the previous dividend payment
date, except that with respect to the first dividend, such dividend shall accrue
from the date of initial issuance. Dividends payable for the first dividend
period and any partial dividend period shall be calculated on the basis of a
360-day year and the actual number of days elapsed in the period for which
payable.

              (ii)   In addition to the dividends payable pursuant to Article
IV.C.3(a)(i), no Excess Dividend (as defined below) shall be paid on or declared
and set apart for the shares of any series of Junior Securities or Parity
Securities, if any, unless at the same time a like dividend for the same
dividend period shall be paid on or declared and set apart with respect to all
outstanding shares of the Senior Preferred Stock in a proportionate amount for
each such share of Senior Preferred Stock, as though the holders of the Senior
Preferred Stock, Junior Securities and Parity Securities, if any, as to which
such dividend is paid or declared and set apart were the holders of the number
of shares of Common Stock represented by, or into which their respective shares
of Senior Preferred Stock, Junior Securities and Parity Securities, if any, are
convertible, as of the record date for the determination of the holders of
securities of the Corporation entitled to receive a proportionate amount of such
Excess Dividend. As used herein, "Excess Dividend" means a dollar amount of
dividends paid on or declared and set apart for the shares of any Junior
Securities or Parity Securities with respect to a dividend period to the extent
that the aggregate dollar amount of such dividends, as a percentage of all
dividends paid on or declared and set apart with respect to Senior Preferred
Stock, Junior Securities and Parity Securities, if any, with respect to such
dividend period exceeds the ratio of (x) the number of shares of Common Stock of
the Corporation represented by, and into which, the shares of Junior Securities
and Parity Securities, if any, as to which such dividends were paid or declared
and set aside are convertible to (y) the number of shares of Common Stock
represented by, and into which, shares of Senior Preferred Stock, Junior
Securities and Parity Securities, if any, are convertible, in each case as of
the first day of such dividend period.

       (b)    In the event the Corporation shall declare a distribution (other
than any distribution pursuant to Article IV.C.3(a)) payable in shares of
capital stock of the Corporation (other than Common Stock) or evidences of its
indebtedness or assets (excluding ordinary cash dividends, which may be an
initial cash dividend, payable out of consolidated earnings or earned surplus
(both of which to be calculated for these purposes excluding charges for
amortization of goodwill and other intangibles) and dividends or distributions
referred to in Article IV.C.6(d)(i) and (ii)), securities of other persons,
evidences of indebtedness issued by other persons, or rights


                                     - 27 -
<PAGE>   28


or warrants to subscribe for or purchase any of such securities, assets or
evidences of indebtedness (excluding those rights with respect to the
Corporation's securities referred to in Article IV.C.6(d)(ii)) (any of the
foregoing being hereinafter called "Securities or Assets"), then, in each such
case the holders of the Senior Preferred Stock shall be entitled to a
proportionate share of any such distribution as though the holders of the Senior
Preferred Stock, Junior Securities and Parity Securities, if any, as to which
such distribution is declared were the holders of the number of shares of Common
Stock represented by, and into which their respective shares of Senior Preferred
Stock, Junior Securities and Parity Securities, if any, are convertible, as of
the record date for the determination of the holders of securities of the
Corporation entitled to receive such distribution.

       (c)    All dividends paid with respect to shares of Senior Preferred
Stock pursuant to Article IV.C.3(a)(i) shall be paid as follows:

              (i)    if the funds legally available for the payment of dividends
are sufficient to pay in full the accrued dividends payable to the holders of
the outstanding shares of Senior Preferred Stock, the accrued dividends on each
share of Senior Preferred Stock shall be paid to the holders; or

              (ii)   if the funds legally available for the payment of dividends
are not sufficient to pay in full the accrued dividends payable to the holders
of the outstanding shares of all Senior Preferred Stock, then the aggregate
amount of funds legally available for the payment shall be distributed as
follows:

                     (A)    an amount equal to the aggregate accrued but unpaid
dividends on outstanding shares of Series E Preferred Stock multiplied by the
"Dividend Distribution Fraction" (as defined below) will be paid to the holders
of Series E Preferred Stock (the "Series E Aggregate Distribution"). The Series
E Aggregate Distribution will be paid to the holders of Series E Preferred Stock
on a proportional basis as to each holder of Series E Preferred Stock as
determined by multiplying the Series E Aggregate Distribution by a fraction
determined by dividing (x) the accrued but unpaid dividends payable to each such
holder of Series E Preferred Stock outstanding by (y) the aggregate amount of
accrued but unpaid dividends payable to the holders of all shares of Series E
Preferred Stock outstanding on the record date for the determination of the
holders of Senior Preferred Stock entitled to receive such dividends;

                     (B)    an amount equal to the aggregate accrued but unpaid
dividends on outstanding shares of Series F Preferred Stock multiplied by the
Dividend Distribution Fraction will be paid to the holders of Series F Preferred
Stock (the "Series F Aggregate Distribution"). The Series F Aggregate
Distribution will be paid to the holders of Series F Preferred Stock on a
proportional basis as to each holder of Series F Preferred Stock as determined
by multiplying the Series F Aggregate Distribution by a fraction determined by
dividing (x) the accrued but unpaid dividends payable to each such holder of
Series F Preferred Stock outstanding by (y) the aggregate amount of accrued but
unpaid dividends payable to the holders of all shares of Series F Preferred
Stock outstanding on the record date for the determination of the holders of
Senior Preferred Stock entitled to receive such dividends; and


                                     - 28 -
<PAGE>   29


                     (C)    an amount equal to the aggregate accrued but unpaid
dividends on outstanding shares of Series G Preferred Stock multiplied by the
Dividend Distribution Fraction will be paid to the holders of Series G Preferred
Stock (the "Series G Aggregate Distribution"). The Series G Aggregate
Distribution will be paid to the holders of Series G Preferred Stock on a
proportional basis as to each holder of Series G Preferred Stock as determined
by multiplying the Series G Aggregate Distribution by a fraction determined by
dividing (x) the accrued but unpaid dividends payable to each such holder of
Series G Preferred Stock outstanding by (y) the aggregate amount of accrued but
unpaid dividends payable to the holders of all shares of Series G Preferred
Stock outstanding on the record date for the determination of the holders of
Senior Preferred Stock entitled to receive such dividends.

For purposes of the foregoing calculations, the "Dividend Distribution Fraction"
shall be a fraction determined by dividing (x) the aggregate amount of funds
legally available for the payment of dividends declared with respect to shares
of Senior Preferred Stock, by (y) the aggregate amount of accrued but unpaid
dividends on the shares of Senior Preferred Stock outstanding on the record date
for the determination of the holders of Senior Preferred Stock entitled to
receive such dividends.

       (d)    No full dividends shall be declared by the Board of Directors or
paid or set apart for payment by the Corporation on any Parity Securities for
any period unless full cumulative dividends have been or contemporaneously are
declared and paid or declared and a sum set apart sufficient for such payment on
the Senior Preferred Stock for all dividend payment periods terminating on or
prior to the date of payment, or setting apart for payment, of such full
dividends on such Parity Securities. If any dividends are not paid in full, as
aforesaid, upon the shares of the Senior Preferred Stock and any other Parity
Securities, all dividends declared upon shares of the Senior Preferred Stock and
any other Parity Securities shall be distributed as follows:

              (i)    an amount equal to the aggregate accrued but unpaid
dividends on outstanding shares of Series E Preferred Stock multiplied by the
"Parity Dividend Distribution Fraction" (as defined below) will be paid to the
holders of Series E Preferred Stock (the "Series E Aggregate Parity
Distribution"). The Series E Aggregate Parity Distribution will be paid to the
holders of Series E Preferred Stock on a proportional basis as to each holder of
Series E Preferred Stock as determined by the multiplying the Series E Aggregate
Parity Distribution by a fraction determined by dividing (x) the accrued but
unpaid dividends payable to each such holder of Series E Preferred Stock
outstanding by (y) the aggregate amount of accrued but unpaid dividends payable
to the holders of all shares of Series E Preferred Stock outstanding on the
record date for the determination of the holders of Senior Preferred Stock and
Parity Securities entitled to receive such dividends;

              (ii)   an amount equal to the aggregate accrued but unpaid
dividends on outstanding shares of Series F Preferred Stock multiplied by the
Parity Dividend Distribution Fraction will be paid to the holders of Series F
Preferred Stock (the "Series F Aggregate Parity Distribution"). The Series F
Aggregate Parity Distribution will be paid to the holders of Series F


                                     - 29 -
<PAGE>   30


Preferred Stock on a proportional basis as to each holder of Series F Preferred
Stock as determined by multiplying the Series F Aggregate Parity Distribution by
a fraction determined by dividing (x) the accrued but unpaid dividends payable
to each such holder of Series F Preferred Stock outstanding by (y) the aggregate
amount of accrued but unpaid dividends payable to the holders of all shares of
Series F Preferred Stock outstanding on the record date for the determination of
the holders of Senior Preferred Stock and Parity Securities entitled to receive
such dividends;

              (iii)  an amount equal to the aggregate accrued but unpaid
dividends on outstanding shares of Series G Preferred Stock multiplied by the
Parity Dividend Distribution Fraction will be paid to the holders of Series G
Preferred Stock (the "Series G Aggregate Parity Distribution"). The Series G
Aggregate Parity Distribution will be paid to the holders of Series G Preferred
Stock on a proportional basis as to each holder of Series G Preferred Stock as
determined by multiplying the Series G Aggregate Parity Distribution by a
fraction determined by dividing (x) the accrued but unpaid dividends payable to
each such holder of Series G Preferred Stock outstanding by (y) the aggregate
amount of accrued but unpaid dividends payable to the holders of all shares of
Series G Preferred Stock outstanding on the record date for the determination of
the holders of Senior Preferred Stock and Parity Securities entitled to receive
such dividends; and

              (iv)   an amount equal to the aggregate accrued but unpaid
dividends on outstanding shares of Parity Securities multiplied by the Parity
Dividend Distribution Fraction will be paid to the holders of Parity Securities
(the "Parity Securities Aggregate Parity Distribution"). The Parity Securities
Aggregate Parity Distribution will be paid to the holders of Parity Securities
on a proportional basis as to each holder of Parity Securities as determined by
multiplying the Parity Securities Aggregate Parity Distribution by a fraction
determined by dividing (x) the accrued but unpaid dividends payable to each such
holder of Parity Securities outstanding by (y) the aggregate amount of accrued
but unpaid dividends payable to the holders of all shares of Parity Securities
outstanding on the record date for the determination of the holders of Senior
Preferred Stock and Parity Securities entitled to receive such dividends.

For purposes of the foregoing calculations, the "Parity Dividend Distribution
Fraction" shall be a fraction determined by dividing (x) the aggregate amount of
funds legally available for the payment of dividends declared with respect to
shares of Senior Preferred Stock and Parity Securities, by (y) the aggregate
amount of accrued but unpaid dividends on the shares of Senior Preferred Stock
and Parity Securities outstanding on the record date for the determination of
the holders of Senior Preferred Stock and Parity Securities entitled to receive
such dividends.

No interest, or sum of money in lieu of interest, shall be payable in respect of
any dividend payment or payments on any Senior Preferred Stock or any other
Parity Securities which may be in arrears. Any dividends not paid pursuant to
Article IV.C.3(a)(i) or this Article IV.C.3(d) shall be fully cumulative and
shall accrue (whether or not declared), without interest, as set forth in
Article IV.C.3(a)(i).

       (e)    (i)    Holders of shares of the Senior Preferred Stock shall be
entitled to receive,


                                     - 30 -
<PAGE>   31


on a pari passu basis, the dividends provided for in Article IV.C. 3(a)(i) in
preference to and in priority over any dividends upon any of the Junior
Securities.

              (ii)   So long as any shares of Senior Preferred Stock are or
remain outstanding, the Board of Directors shall not declare, and the
Corporation shall not pay or set apart for payment any dividend on any of the
Junior Securities or take any payment on account of, or set apart for payment
money for a sinking or other similar fund for, the repurchase, redemption or
other retirement of, any of the Junior Securities or Parity Securities or any
warrants, rights or options exercisable for or convertible into any of the
Junior Securities or Parity Securities (other than purchases or redemptions
pursuant to or in accordance with employee stock control, subscription or
option agreements entered into between the Corporation and its or its
subsidiaries' directors, officers and employees prior to the Original Series F
Issue Date and other than the repurchase, redemption or other retirement of
debentures or other debt securities that are convertible or exchangeable into
any of the Junior Securities or Parity Securities), or make any distribution in
respect of the Junior Securities, either directly or indirectly, whether in
cash, obligations or shares of the Corporation or other property (other than
distributions or dividends in Junior Securities to the holders of Junior
Securities), and shall not permit any corporation or other entity directly or
indirectly controlled by the Corporation to purchase or redeem any of the
Junior Securities or Parity Securities or any warrants, rights, calls or
options exercisable for or convertible into any of the Junior Securities or
Parity Securities (other than purchases or redemptions pursuant to or in
accordance with employee agreements entered into between the Corporation and
certain of its or its subsidiaries' directors, officers and employees prior to
the Original Series F Issue Date and other than the repurchase, redemption or
other retirement of debentures or other debt securities that are convertible or
exchangeable into any of the Junior Securities or Parity Securities) unless
prior to or concurrently with such declaration, payment, setting apart for
payment, repurchase, redemption or other retirement or distribution, as the
case may be, all accrued and unpaid dividends on shares of the Senior Preferred
Stock not paid on the dates provided for in Article IV.C.3(a)(i) (including
accrued dividends not paid by reason of the terms and conditions of Article
IV.C.3(a)(i) or Article IV.C.3(d)) shall have been or are paid.

       (f)    Subject to the foregoing provisions of this Article IV.C.3, the
Board of Directors may declare, and the Corporation may pay or set apart for
payment, dividends and other distributions on any of the Junior Securities or
Parity Securities, and may repurchase, redeem or otherwise retire any of the
Junior Securities or Parity Securities or any warrants, rights or options
exercisable for or convertible into any of the Junior Securities or Parity
Securities, and the holders of shares of Senior Preferred Stock shall not be
entitled to share therein.

       (g)    The payment of dividends on all shares of Senior Preferred Stock
outstanding at any time or times may be waived in writing by the holders of (i)
sixty percent (60%) of the voting power of the then outstanding Series E
Preferred Stock and Series G Preferred Stock, voting together as a separate
single class on the basis of one vote for each share of Series E Preferred Stock
and Series G Preferred Stock then outstanding; and (ii) sixty-six and two thirds
percent (66-2/3%) of the voting power of the then outstanding Series F Preferred
Stock, voting as a separate single class on the basis of one vote for each share
of Series F Preferred Stock then outstanding.

       4.     Liquidation Preference. (a) In the event of any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the
Corporation, the holders of shares of Senior Preferred Stock then outstanding
shall be entitled to be paid out of the assets of the Corporation available for
distribution to its stockholders an amount ("Aggregate Liquidation Amount") in
cash equal to the greater of:

              (i)    the Stated Value of each share of Senior Preferred Stock
outstanding plus all accrued but unpaid dividends thereon to the date of
liquidation, dissolution or winding up; or

              (ii)   the amount that would be distributable to the holders of
the Senior Preferred Stock if the entire remaining assets and funds of the
Corporation legally available for distribution, if any, were to be distributed
among the holders of the Senior Preferred Stock, Junior Securities and Parity
Securities, if any, in proportion to the number of shares of Common Stock
represented by, and into which their respective shares of Senior Preferred
Stock, Junior Securities and Parity Securities, if any, are convertible, as of
the date of liquidation, dissolution or winding up, before any payment shall be
made or any assets distributed to the holders of any of the Junior Securities.

       (b)    If the Aggregate Liquidation Amount is the amount set forth in
Article IV.C.4(a)(i), then the amount available for distribution shall be
distributed as follows:

              (i)    an amount equal to the aggregate Stated Value of each share
of Series E Preferred Stock outstanding, plus accrued but unpaid dividends
thereon, multiplied by the "Liquidation Preference Distribution Fraction" (as
defined below), will be paid to the holders of Series E Preferred Stock (the
"Series E Liquidation Distribution"). The Series E Liquidation Distribution will
be paid to the holders of Series E Preferred Stock on a proportional basis as to
each holder of Series E Preferred Stock as determined by multiplying the Series
E Liquidation Distribution by a fraction determined by dividing (x) the
aggregate Stated Value of Series E Preferred Stock held by each such holder of
Series E Preferred Stock outstanding as of the date of liquidation, dissolution
or winding up, plus the accrued but unpaid dividends payable thereon by (y) the
aggregate Stated Value of all shares of Series E Preferred Stock outstanding as
of the date of liquidation, dissolution or winding up, plus the aggregate amount
of accrued but unpaid dividends payable thereon;

              (ii)   an amount equal to the aggregate Stated Value of each share
of Series F Preferred Stock outstanding, plus accrued but unpaid dividends
thereon, multiplied by the Liquidation Preference Distribution Fraction, will be
paid to the holders of Series F Preferred Stock (the "Series F Liquidation
Distribution"). The Series F Liquidation Distribution will be paid to the
holders of Series F Preferred Stock on a proportional basis as to each holder of
Series F Preferred Stock as determined by multiplying the Series F Liquidation
Distribution by a fraction determined by dividing (x) the aggregate Stated Value
of Series F Preferred Stock held by each such holder of Series F Preferred Stock
as of the date of liquidation, dissolution or winding up, plus the accrued but
unpaid dividends payable thereon by (y) the aggregate Stated Value of all shares
of Series F Preferred Stock outstanding as of the date of liquidation,


                                     - 32 -
<PAGE>   33


dissolution or winding up plus the aggregate amount of accrued but unpaid
dividends payable thereon; and

              (iii)  an amount equal to the aggregate Stated Value of each share
of Series G Preferred Stock outstanding, plus accrued but unpaid dividends
thereon, multiplied by the Liquidation Preference Distribution Fraction, will be
paid to the holders of Series G Preferred Stock (the "Series G Liquidation
Distribution"). The Series G Liquidation Distribution will be paid to the
holders of Series G Preferred Stock on a proportional basis as to each holder of
Series G Preferred Stock as determined by multiplying the Series G Liquidation
Distribution by a fraction determined by dividing (x) the aggregate Stated Value
of Series G Preferred Stock held by each such holder of Series G Preferred Stock
as of the date of liquidation, dissolution or winding up, plus the accrued but
unpaid dividends payable thereon by (y) the aggregate Stated Value of all shares
of Series G Preferred Stock outstanding as of the date of liquidation,
dissolution or winding up plus the aggregate amount of accrued but unpaid
dividends payable thereon.

For purposes of the foregoing calculations, "Liquidation Preference Distribution
Fraction" shall be a fraction determined by dividing (x) the aggregate amount of
assets and funds available for payment of the Aggregate Liquidation Amount by
(y) the aggregate Stated Value of each share of Senior Preferred Stock
outstanding plus all accrued but unpaid dividends thereon to the date of
liquidation, dissolution or winding up.

       (c)    If the Aggregate Liquidation Preference is the amount set forth in
Article IV.C.4(a)(ii), then the amount available for distribution shall be
distributed as follows:

              (i)    (A)    an amount equal to the Stated Value of each share of
       Series E Preferred Stock outstanding shall be paid to each holder of
       Series E Preferred Stock;

                     (B)    an amount equal to the Stated Value of each share of
       Series F Preferred Stock outstanding shall be paid to each holder of
       Series F Preferred Stock; and

                     (C)    an amount equal to the Stated Value of each share of
       Series G Preferred Stock outstanding shall be paid to each holder of
       Series G Preferred Stock; and

              (ii)   the balance of the Aggregate Liquidation Preference shall
be paid to the holders of Senior Preferred Stock outstanding as of the date of
liquidation, dissolution or winding up on a pro rata basis in proportion to the
number of shares of Common Stock into which such shares of Senior Preferred
Stock are then convertible.

       (d)    After payment to the holders of the Senior Preferred Stock of the
amounts set forth in Article IV.C.4(a), the remaining assets and funds of the
Corporation legally available for distribution, if any, shall be distributed
among the holders of the Collective Preferred Stock and Common Stock as provided
in Article IV.B.2.

       (e)    (i)    For purposes of this Article IV.C.4, a Change of Control
(as defined


                                     - 33 -
<PAGE>   34


below) shall, at the option of each holder of Senior Preferred Stock with an
aggregate Stated Value of not less than $1,000,000, upon written notice to the
Corporation prior to the closing of the transaction that constitutes a Change of
Control, be treated as a liquidation, dissolution or winding up of the
Corporation with respect to such holder and shall entitle the electing holders
of Senior Preferred Stock to receive, at the closing of the transaction that
constitutes a Change of Control, in cash, securities or other property (valued
as provided in Article IV.C.4(f) below), amounts as specified in Article
IV.C.4(a), (b) and (c) above; provided, however, that when such payments are
made as a result of a Change of Control that is treated as a liquidation,
dissolution, or winding up of the Corporation, the payment to be made pursuant
to this Article IV.C.4(e) shall be made only upon surrender of the certificate
or certificates for the shares of Senior Preferred Stock with respect to which
such payment is to be made, and, from and after the date that the certificate or
certificates for such shares are required to be surrendered (whether or not such
certificate or certificates are surrendered on such date), all rights (other
than the right to receive payment as provided in this Article IV.C.4(e) upon
surrender of such certificate or certificates) with respect to such shares shall
terminate, and such shares be deemed to be canceled and retired. Notwithstanding
the foregoing, a Change of Control shall not be treated as a liquidation,
dissolution or winding up of the Corporation with respect to any holder of the
Senior Preferred Stock if the holders of (i) sixty percent (60%) of the voting
power of the then outstanding Series E Preferred Stock, voting as a separate
single class on the basis of one vote for each share of Series E Preferred Stock
then outstanding, (ii) sixty-six and two thirds percent (66-2/3%) of the voting
power of the then outstanding Series F Preferred Stock, voting as a separate
single class on the basis of one vote for each share of Series F Preferred Stock
then outstanding, and (iii) sixty percent (60%) of the voting power of the then
outstanding Series G Preferred Stock, voting as a separate single class on the
basis of one vote for each share of Series G Preferred Stock then outstanding,
waive in writing the provisions of this Article IV.C.4(e), as applicable, prior
to definitive authorization by the Board of Directors of such transaction or
prior to the order of such court or administrative body requiring such
reorganization.

              (ii)   "Change of Control" means (x) the sale, lease, conveyance
or other disposition of all or substantially all of the Corporation's assets as
an entirety or substantially as an entirety to any person or "group" (within the
meaning of Section 13(d)(3) of the Exchange Act) in one or a series of
transactions, provided that a transaction where the holders of all classes of
voting stock of the Corporation immediately prior to such transaction own,
directly or indirectly, more than 50% of the aggregate voting power of all
classes of voting stock of such person or group immediately after such
transaction shall not be a Change of Control; or (y) any transaction or series
of transactions (as a result of a tender offer, merger, consolidation or
otherwise, but not as a result of the issuance of Senior Preferred Stock or of a
Qualified Public Offering as defined in Article IV.C.6(j)(i) hereof) that
results in, or that is in connection with, any person, including a "group"
(within the meaning of Section 13(d)(3) of the Exchange Act) that includes such
person, acquiring "beneficial ownership" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of 50% or more of the aggregate voting
power of all classes of voting stock of the Corporation or any person that
possesses "beneficial ownership" (as defined in Rule 13d-3 under the Exchange
Act), directly or indirectly, of 50% or more of the aggregate voting power of
all classes of voting stock of the Corporation.

       (f)    Whenever the distribution provided for in this Article IV.C.4
shall be payable in securities or property other than cash, the value of such
distribution shall be the fair market value of such securities or other property
as determined in good faith by the Board of Directors of the Corporation.

       5.     Redemption. The Corporation shall not have the right to call or
redeem any shares of Senior Preferred Stock.

       6.     Conversion.

       (a)    Right to Convert. Upon the terms and in the manner set forth in
this Article IV.C.6 and subject to the provisions for adjustment contained in
Article IV.C.6(d), each share of Senior Preferred Stock shall be convertible, at
the option of the holder thereof at any time, upon surrender to the Corporation
of the certificates for the shares to be converted, into a number of fully paid
and nonassessable shares of Common Stock as is determined by dividing the
applicable Stated Value of such Senior Preferred Stock by the applicable
Conversion Price (as defined below) in effect at the time of conversion. The
conversion price for the Series E Preferred Stock shall be $0.035619838954 per
share, subject to adjustment as provided below (the "Series E Conversion
Price"). The conversion price for the Series F Preferred Stock shall be
$0.05526523774 per share, subject to adjustment as provided below (the "Series F
Conversion Price"). The conversion price for the Series G Preferred Stock shall
be $0.13 per share, subject to adjustment as provided below (the "Series G
Conversion Price").

Each of the "Series E Conversion Price," the "Series F Conversion Price," and
the "Series G Conversion Price" may be referred to herein as the "Conversion
Price," but the Conversion Price applicable to Series E Preferred Stock shall
only be the "Series E Conversion Price," the Conversion Price applicable to
Series F Preferred Stock shall only be the "Series F Conversion Price" and the
Conversion Price applicable to the Series G Preferred Stock shall only be the
"Series G Conversion Price".

Subject to Article IV.C.6(j)(i), in the event that at the time of the conversion
of a holder's Series E Preferred Stock, Series F Preferred Stock, or Series G
Preferred Stock there are accrued but unpaid cash dividends, whether or not
declared, on such Series E Preferred Stock, Series F Preferred Stock, or Series
G Preferred Stock such cash dividend payable to a holder of Series E Preferred
Stock, Series F Preferred Stock, or Series G Preferred Stock pursuant to Article
IV.C.3(a) shall be paid and distributed to such holder of Series E Preferred
Stock, Series F Preferred Stock, or Series G Preferred Stock immediately prior
to the conversion of such holder's Series E Preferred Stock, Series F Preferred
Stock, or Series G Preferred Stock; provided that if a holder intends to convert
only a portion of its Series E Preferred Stock, Series F Preferred Stock, or
Series G Preferred Stock the cash dividend payable to such holder immediately
prior to such conversion shall be that dollar amount which is proportionate to
the number of shares of Series E Preferred Stock, Series F Preferred Stock, or
Series G Preferred Stock which such holder intends to convert. If pursuant to
and in accordance with Article IV.C.3(a) the Corporation cannot distribute all
or a portion of such cash dividend immediately prior to such conversion, then
the Corporation shall distribute the balance of such cash dividend as soon as
assets or funds are


                                     - 35 -
<PAGE>   36


available for such distribution under and in accordance with Article IV.C.3(a).

       (b)    Mechanics of Conversion.

              (i)    In order for a holder of Series E Preferred Stock, Series F
Preferred Stock, or Series G Preferred Stock to convert shares of Series E
Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock into
shares of Common Stock, such holder shall surrender the certificate or
certificates for such shares of Series E Preferred Stock, Series F Preferred
Stock, or Series G Preferred Stock at the office of the transfer agent for the
Senior Preferred Stock (or at the principal office of the Corporation if the
Corporation serves as its own transfer agent), together with written notice that
such holder elects to convert all or any number of shares of the Series E
Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock
represented by such certificate of certificates. Such notice shall state such
holder's name or the names of the nominees in which such holder wishes the
certificate or certificates for shares of Common Stock to be issued. If required
by the Corporation, certificates surrendered for conversion shall be endorsed or
accompanied by a written instrument or instruments of transfer, in form
satisfactory to the Corporation, duly executed by the registered holder or his,
her or its attorney duly authorized in writing. The date of receipt of such
certificates and notice by the transfer agent (or by the Corporation if the
Corporation serves as its own transfer agent) shall be the conversion date
("Conversion Date"). The Corporation shall, as soon as practicable after the
Conversion Date, issue and deliver at such office to such holder of Series E
Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock or to
his, her or its nominees, a certificate or certificates for the number of shares
of Common Stock to which such holder shall be entitled. No fractional shares
shall be issued upon conversion of the Series E Preferred Stock, Series F
Preferred Stock, or Series G Preferred Stock, and the number of shares of Common
Stock to be issued shall be rounded up to the nearest whole share. In
determining the number of shares of Common Stock issuable upon conversion, each
holder's Series E Preferred Stock, Series F Preferred Stock, Series G Preferred
Stock and Collective Preferred Stock being converted on the same day shall be
aggregated.

              (ii)   The Corporation shall at all times when any Series E
Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock shall be
outstanding, reserve and keep available out of its authorized but unissued
stock, for the purpose of effecting the conversion of the Series E Preferred
Stock, Series F Preferred Stock, or Series G Preferred Stock, such number of its
duly authorized shares of Common Stock as shall from time to time be sufficient
to effect the conversion of all outstanding shares of Series E Preferred Stock,
Series F Preferred Stock, and Series G Preferred Stock. Before taking any action
which would cause an adjustment reducing the Conversion Price below the then par
value of the shares of Common Stock issuable upon conversion of the Series E
Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock, the
Corporation will take any corporate action which may, in the opinion of its
counsel, be necessary in order that the Corporation may validly and legally
issue fully paid and nonassessable shares of Common Stock at such adjusted
Conversion Price.

              (iii)  On the Conversion Date, all shares of Series E Preferred
Stock, Series F Preferred Stock, and Series G Preferred Stock which shall have
been surrendered for conversion


                                     - 36 -
<PAGE>   37


as herein provided shall no longer be deemed to be outstanding and all rights
with respect to such shares, including the rights, if any, to receive notices
and to vote such Series E Preferred Stock, Series F Preferred Stock, and Series
G Preferred Stock shall immediately cease and terminate on the Conversion Date,
except only the right of the holders thereof to receive shares of Common Stock
in exchange therefor.

              (iv)   If the conversion is in connection with an underwritten
offering of securities registered pursuant to the Securities Act of 1933, as
amended, which is not a Qualified Public Offering as defined in Article
IV.C.6(j)(i), the conversion may, at the option of any holder tendering Series E
Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock for
conversion, be conditioned upon the closing with the underwriter of the sale of
securities pursuant to such offering, in which event the person(s) entitled to
receive the Common Stock issuable upon such conversion of Series E Preferred
Stock, Series F Preferred Stock, or Series G Preferred Stock shall not be deemed
to have converted such Series E Preferred Stock, Series F Preferred Stock, or
Series G Preferred Stock until immediately prior to the closing of the sale of
securities.

       (c)    Dividends Payable. The holders of shares of Series E Preferred
Stock, Series F Preferred Stock and Series G Preferred Stock at the close of
business on a dividend payment record date shall be entitled to receive the
dividend payable on such shares on the corresponding dividend payment date
notwithstanding the conversion thereof or the Corporation's default in payment
of the dividend due on such dividend payment date.

       (d)    Adjustments to Conversion Price. The applicable Conversion Price
shall be subject to adjustment as described below as a result of events taking
place at any time or from time to time after the Original Issue Date as to
Series E Preferred Stock, the Original Series F Issue Date with respect to
Series F Preferred Stock and the Original Series G Issue Date (as hereinafter
defined) with respect to the Series G Preferred Stock.

For purposes of this Certificate of Incorporation the date on which a share of
Series G Preferred Stock was first issued is defined as the "Original Series G
Issue Date".

              (i)    Stock Dividends, Splits and Reclassifications. If the
Corporation shall (w) declare or pay a dividend on its outstanding Common Stock
in shares of Common Stock or make a distribution to all holders of its Common
Stock in shares of Common Stock, (x) subdivide its outstanding shares of Common
Stock into a greater number of shares of Common Stock, (y) combine its
outstanding shares of Common Stock into a smaller number of shares of Common
Stock or (z) issue by reclassification of its shares of Common Stock other
securities of the Corporation, then the Series E Conversion Price, Series F
Conversion Price, and the Series G Conversion Price in effect immediately prior
thereto shall be adjusted so that the holder of any shares of Series E Preferred
Stock, Series F Preferred Stock, or Series G Preferred Stock thereafter
converted shall be entitled to receive the number and kind of shares of Common
Stock of other securities that the holder would have owned or have been entitled
to receive after the happening of any of the events described above had such
shares of Series E Preferred Stock, Series F Preferred Stock, or Series G
Preferred Stock been converted immediately prior to the


                                     - 37 -
<PAGE>   38


happening of such event or any record date with respect thereto. An adjustment
made pursuant to this Article IV.C.6(d)(i) shall become effective on the date of
the dividend payment, subdivision, combination or issuance retroactive to the
record date with respect thereto, if any, for such event. Such adjustments shall
be made successively.

              (ii)   Rights, Options, and Convertible and Exchangeable
Securities. If the Corporation shall issue, without charge to holders of its
Common Stock or Preferred Stock, rights, options, warrants or convertible or
exchangeable securities containing the right to subscribe for or purchase shares
of Common Stock (excluding "Excluded Securities" as defined in Article
IV.C.6(d)(iv) below) at a price per share (the "Rights Price") that is lower
than the then current Series E Conversion Price, Series F Conversion Price or
Series G Conversion Price at the record date mentioned below, the Series E
Conversion Price, the Series F Conversion Price and/or the Series G Conversion
Price, as the case may be, shall be adjusted to be equal to the Rights Price.
The adjustment shall be made successively whenever any such rights, options,
warrants or convertible or exchangeable securities are issued, and shall become
effective immediately after the record date for the determination of
stockholders entitled to receive the rights, options, warrants or convertible or
exchangeable securities. If all such rights, options, warrants or convertible or
exchangeable securities expire or terminate without having been converted,
exchanged or exercised, as the case may be, then, subject to the other
provisions of this Article IV.C.6 and successive applications of this Article
IV.C.6(d)(ii), the Conversion Price shall be recalculated and adjusted to the
amount such Conversion Price would have been assuming (but taking into account
all subsequent issuances of securities by the Company) that such expired or
terminated rights, options, warrants or convertible or exchangeable securities
had never been issued by the Corporation.

              (iii)  Dividends in Kind. In case the Corporation shall distribute
to all holders of its outstanding Common Stock any Securities or Assets (as
defined in Article IV.C.3(b)) that, for any reason, are not distributed to
holders of the Series E Preferred Stock, Series F Preferred Stock, or Series G
Preferred Stock pursuant to Article IV.C.3(b), then in each such case, unless
the Corporation elects to reserve shares or other units of such Securities or
Assets for distribution to the holders of the Series E Preferred Stock, Series F
Preferred Stock and Series G Preferred Stock upon the conversion of the shares
of Series E Preferred Stock, Series F Preferred Stock, and Series G Preferred
Stock so that any such holder converting shares of Series E Preferred Stock,
Series F Preferred Stock, or Series G Preferred Stock, as the case may be, will
receive upon such conversion, in addition to the shares of Common Stock to which
such holder is entitled, the amount and kind of such Securities or Assets which
such holder would have received if such holder had, immediately prior to the
record date for the distribution of the Securities or Assets, converted its
shares of Series E Preferred Stock, Series F Preferred Stock, or Series G
Preferred Stock into Common Stock, the Series E Conversion Price, the Series F
Conversion Price, and the Series G Conversion Price shall be adjusted so that
the same shall equal the price determined by multiplying the applicable
Conversion Price in effect immediately prior to the date of such distribution by
a fraction of which the numerator shall be the current market price per share
(as determined in accordance with Article IV.C.6(d)(v)) of the Common Stock on
the record date mentioned below less the then fair market value (as determined
by the Board of Directors, whose determination shall, if made in good faith, be
conclusive) of the


                                     - 38 -
<PAGE>   39


portion of the capital stock or assets or evidences of indebtedness so
distributed or of such rights or warrants applicable to one share of Common
Stock, and of which the denominator shall be the current market price per share
of the Common Stock on such record date. Such adjustment shall become effective
immediately after the record date for the determination of stockholders entitled
to receive such distribution, except as provided in Article IV.C.6(d)(i) above.

              (iv)   Issuances Below Conversion Price. If the Corporation shall
issue without charge or sell and issue any shares of Common Stock, rights,
options, warrants or convertible or exchangeable securities containing the right
to subscribe for or purchase shares of Common Stock (excluding the "Excluded
Securities" as defined below in this Article IV.C.6(d)(iv)) at a price per share
(determined, in the case of rights, options, warrants or convertible or
exchangeable securities, by dividing (x) the total amount received or receivable
by the Corporation in consideration of the sale and issuance of such rights,
options, warrants or convertible or exchangeable securities, plus the total
consideration payable to the Corporation upon exercise or conversion or exchange
thereof, by (y) the total number of shares of Common Stock covered by such
rights, options, warrants or convertible or exchangeable securities) (the
"Issuance Price") that is lower than the then current Series E Conversion Price,
the Series F Conversion Price or the Series G Conversion Price immediately prior
to such sale and issuance, then in each case the Series E Conversion Price, the
Series F Conversion Price and/or the Series G Conversion Price, as the case may
be, shall be adjusted to be equal to the Issuance Price. For the purposes of
such adjustment, the consideration received or receivable by the Corporation
therefor shall be deemed to be the consideration received or receivable by the
Corporation (plus any discounts or commissions in connection therewith) for such
rights, options, warrants or convertible or exchangeable securities, plus the
consideration or premiums stated in such rights, options, warrants or
convertible or exchangeable securities to be paid for the shares of Common Stock
purchasable thereby. In case the Corporation shall (x) sell and issue shares of
Common Stock for a consideration consisting, in whole or in part, of property
other than cash or its equivalent or (y) sell and issue shares of Common Stock
together with one or more other securities as part of a unit at a price per
unit, then in determining the "price per share" and the "consideration received
or receivable by the Corporation" for purposes of the first sentence and the
immediately preceding sentence of this Article IV.C.6(d)(iv), the Board of
Directors shall determine, in its discretion, the fair value of said property or
the shares of Common Stock then being sold as part of such unit, as the case may
be, and such determination, if made in good faith, shall be binding. If all such
rights, options, warrants or convertible or exchangeable securities expire or
terminate without having been converted, exchanged or exercised, as the case may
be, then, subject to the other provisions of this Article IV.C.6 and successive
applications of this Article IV.C.6(d)(iv), the Conversion Price shall be
recalculated and adjusted to the amount such Conversion Price would have been
assuming (but taking into account all subsequent issuances of securities by the
Company) that such expired or terminated rights, options, warrants or
convertible or exchangeable securities had never been issued by the Corporation.
The adjustments required by this Article IV.C.6(d)(iv) shall be made
successively whenever any such shares of Common Stock, rights, options, warrants
or convertible or exchangeable securities containing the right to subscribe for
or purchase shares of Common Stock are issued for less then the current Series E
Conversion Price, the Series F Conversion Price and/or the Series G Conversion
Price, as the case may be, subject to the exceptions noted above with respect to
the


                                     - 39 -
<PAGE>   40


Excluded Securities, and shall become effective immediately after the issue
date.

       As used in this Article IV.C.6(d)(iv) and Article IV.C.6(d)(ii) above,
"Excluded Securities" means and includes the following:

                     (A)    shares of Common Stock, rights, options, warrants or
convertible or exchangeable securities containing the right to subscribe for or
purchase shares of Common Stock issued in any of the transactions described in
paragraphs (i), (ii) and (iii) above;

                     (B)    any shares of Common Stock, options or warrants to
purchase shares of Common Stock issued or granted on or before August 31, 1999
and the shares of Common Stock issuable upon the exercise of such options or
warrants;

                     (C)    any shares of Preferred Stock or warrants to
purchase shares of Preferred Stock issued on or before August 31, 1999, the
shares of Preferred Stock issuable upon the exercise of such warrants and the
shares of Common Stock issuable upon conversion of such shares of Preferred
Stock; and

                     (D)    shares of Common Stock issued to or issuable upon
the exercise of stock options or other rights to be granted to existing or
future officers, employees, directors or contractors of the Corporation or its
subsidiaries with an exercise price between $0.035619838954 per share and
$0.05526523774 per share (the "Excluded Options"), provided that upon the grant
of any Excluded Options (with the date of each such grant being referred to
herein as an "Excluded Option Grant Date"), the number of shares of Common Stock
underlying the Excluded Options being granted on any particular Excluded Option
Grant Date, and the number of shares of Common Stock underlying all options
granted to past and existing employees, directors, or contractors under the
Company's stock option plans shall not at any time exceed the aggregate of
212,870,132 (including 54,854,298 "Additional Excluded Options" as defined
below) shares of Common Stock.

                     (E)    shares of Common Stock issued to or issuable upon
the exercise of stock options or other rights to be granted to existing or
future officers, employees, directors or contractors of the Corporation or its
subsidiaries with an exercise price between $0.05526523774 per share and $0.13
per share (the "Additional Excluded Options"), provided that upon the grant of
any Additional Excluded Options (with the date of each such grant being referred
to herein as an "Additional Excluded Option Grant Date"), the number of shares
of Common Stock underlying the Additional Excluded Options being granted on any
particular Additional Excluded Option Grant Date, and the number of shares of
Common Stock underlying the Additional Excluded Options shall not at any time
exceed the aggregate of 54,854,298 shares of Common Stock.

       For purposes of this Certificate of Incorporation the date on which a
share of Series E Preferred Stock was first issued is defined as the "Original
Issue Date."

       (v)    Current Market Price. For the purposes of any computation of
current


                                     - 40 -
<PAGE>   41


market price per share under Section (6)(d)(iii), the current market price per
share of Common Stock at any date shall be deemed to be the average of the daily
closing prices for the 20 consecutive trading days commencing on the 30th
trading day prior to the date in question. The closing price for each day shall
be (v) the average of the highest and lowest trading price of a share of Common
Stock of the Corporation on the principal national securities exchange on which
such stock is then listed or admitted to trading on such date, or, if no trade
occurs on such date, the average of the reported closing bid and asked prices on
such date on such exchange, or (w) if such stock is not then listed or admitted
to trading on any national securities exchange but is designated as a National
Market System Security by the National Association of Securities Dealers, the
last reported trading price of such stock on such National Market System on such
date, or (x) if there shall have been no trading on such National Market System
on such date or if such stock is not so designated, the average of the reported
closing bid and asked prices of such stock on such date as shown by the National
Association of Securities Dealers Automated Quotation System ("NASDAQ"), or (y)
if such stock is not quoted on NASDAQ, the average of the firm bid and offer
prices for such stock as reported on the NASDAQ OTC Bulletin Board Display
Service on such date or the average of the then most recently reported such
prices, or (z) if such stock is not quoted on the NASDAQ OTC Bulletin Board
Display Service, the average of the bid and asked prices for such stock on such
date as reported in the "pink sheets" published by the National Quotation Bureau
or as quoted by any member firm of the New York Stock Exchange selected by the
Board. In the event such closing prices are unavailable, the current market
price shall be deemed to be the fair market value as determined in good faith by
the Board of Directors, on the basis of such relevant factors as it in good
faith considers, in the reasonable judgment of the Board of Directors,
appropriate.

       (vi)   Adjustment for Merger or Reorganization, etc. In case of any
consolidation or merger of the Corporation with or into another corporation
(other than a Change of Control which is treated as a liquidation pursuant to
Article IV.C.4(e) by the holders of a majority of the Senior Preferred Stock
then outstanding), the authorized capital of the surviving or resulting
corporation (referred to herein as the "surviving corporation") shall include
provision for a class or classes of senior preferred stock having rights,
preferences and limitations substantially economically equivalent to the Senior
Preferred Stock with respect to the capital structure of the Corporation
immediately prior to such consolidation or merger, including provision for each
holder of each share of Senior Preferred Stock, as the case may be, to receive
the preferred stock of the surviving corporation which corresponds to such
series on a substantially economically equivalent basis and which shall
thereafter be convertible into the kind and amount of shares of stock or other
securities of the surviving corporation or other property to which a holder of
the number of shares of Common Stock of the Corporation deliverable upon
conversion of such Senior Preferred Stock would have been entitled upon such
consolidation or merger; and, in such case, appropriate adjustment (as
determined in good faith by the Board of Directors) shall be made in the
application of the provisions set forth in this Article IV.C.6 with respect to
the rights and interest thereafter of the holders of Senior Preferred Stock to
the end that the provisions set forth in this Article IV.C.6 (including
provisions with respect to changes in and other adjustments of the Conversion
Price) shall thereafter be applicable, as nearly as reasonably may be, in
relation to any shares of stock or other securities of the surviving corporation
or other property thereafter deliverable upon the conversion of the


                                     - 41 -
<PAGE>   42


Senior Preferred Stock.

              (vii)  References to Common Stock. For the purposes of this
Article IV.C.6(d) and Article IV.C.(g) below, the term "shares of Common Stock"
shall mean (x) the class of stock designated as the Common Stock of the
Corporation at the date hereof or (y) any other class of stock resulting from
successive changes or reclassifications of such shares consisting solely of
changes in par value, or from no par value to par value. In the event that at
any time, as a result of an adjustment made pursuant to Article IV.C.6(d)(i),
(iii) or (vi), the holders of Senior Preferred Stock shall become entitled to
receive any securities other than shares of Common Stock, thereafter the number
of such other securities so issuable upon conversion of the shares of Series E
Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to the shares of Series
E Preferred Stock, Series F Preferred Stock, or Series G Preferred Stock, as the
case may be, contained in this Article IV.C.6(d).

              (viii) Deferral of Issuance of Common Stock. Notwithstanding the
foregoing, in any case in which this Article IV.C.6(d) provides that an
adjustment shall become effective immediately after a record date for an event,
the Corporation may defer until the occurrence of such event issuing to the
holder of any share of Series E Preferred Stock, Series F Preferred Stock or
Series G Preferred Stock converted after such record date and before the
occurrence of such event the additional shares of Common Stock issuable upon
such conversion before giving effect to such adjustment.

       (e)    Issue and Transfer Taxes. The Corporation will pay any and all
documentary, stamp or similar issue or transfer taxes payable in respect of the
issue or delivery of shares of Common Stock on the conversion of shares of
Senior Preferred Stock pursuant to this Article IV.C.6; provided, however, that
the Corporation shall not be required to pay any tax which may be payable in
respect of any registration of transfer involved in the issue or delivery of
shares of Common Stock in a name other than that of the registered holder of
Senior Preferred Stock converted or to be converted, and no such issue or
delivery shall be made unless and until the person requesting such issue has
paid to the Corporation the amount of any such tax or has established, to the
satisfaction of the Corporation, that such tax has been paid.

       (f)    No Impairment. Except as permitted by applicable law and the
Certificate of Incorporation, including this Article IV.C., the Corporation will
not, by amendment of its Certificate of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Article IV.C.6 and in the taking of
all such action as may be necessary or appropriate in order to protect the
conversion rights of the holders of Senior Preferred Stock against impairment.

       (g)    Certificate as to Adjustments. Upon the occurrence of each
adjustment of the Conversion Price pursuant to this Article IV.C.6, the
Corporation at its expense shall promptly


                                     - 42 -
<PAGE>   43


compute such adjustment in accordance with the terms hereof and furnish to each
holder of Senior Preferred Stock a certificate setting forth such adjustment and
showing in detail the facts upon which such adjustment is based. The Corporation
shall, upon the written request at any time of any holder of Senior Preferred
Stock, furnish or cause to be furnished to such holder a similar certificate
setting forth (i) such adjustments, (ii) the Conversion Price then in effect,
and (iii) the number of shares of Common Stock and the amount, if any, of other
property which then would be received upon the conversion of Series E Preferred
Stock, Series F Preferred Stock or Series G Preferred Stock, as the case may be.

       (h)    Notice of Record Date. In the event:

              (i)    that the Corporation declares a dividend (or any other
distribution) on its Common Stock payable in Common Stock or other securities of
the Corporation;

              (ii)   that the Corporation subdivides or combines its outstanding
shares of Common Stock;

              (iii)  of any reclassification of the Common Stock of the
Corporation (other than a subdivision or combination of its outstanding shares
of Common Stock or a stock dividend or stock distribution thereon), or of any
consolidation or merger of the Corporation into or with another corporation, or
of the sale of all or substantially all of the assets of the Corporation or of
any other Change of Control; or

              (iv)   of the involuntary or voluntary dissolution, liquidation or
winding up of the Corporation;

then the Corporation shall cause to be filed at its principal office or at the
office of the transfer agent of the Senior Preferred Stock, and shall cause to
be mailed to the holders of Senior Preferred Stock at their last addresses as
shown on the records of the Corporation or such transfer agent, at least ten
(10) days prior to the record date specified in (A) below or twenty (20) days
before the date specified in (B) below, a notice stating:

                     (A)    the record date of such dividend, distribution,
subdivision or combination, or, if a record is not to be taken, the date as of
which the holders of Common Stock of record to be entitled to such dividend,
distribution, subdivision or combination are to be determined, or

                     (B)    the date on which such reclassification,
consolidation, merger, sale, Change of Control, dissolution, liquidation or
winding up is expected to become effective, and the date as of which it is
expected that holders of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities or other property deliverable upon
such reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up.

              (i)    Notices. Any notice required by the provisions of this
Article IV.C.6 to be given to the holders of shares of Senior Preferred Stock
shall be deemed given if deposited in the


                                     - 43 -
<PAGE>   44


United States mail, first class, postage prepaid, and addressed to each holder
of record at its address appearing on the books of the Corporation.

       (j)    Mandatory Conversion

              (i)    Mandatory Conversion Event. All holders of shares of Senior
Preferred Stock then outstanding shall convert their shares of Senior Preferred
Stock into shares of Common Stock, at the then effective Conversion Price
pursuant to this Article IV.C.6, upon the closing of a Qualified Public
Offering. Notwithstanding any provision to the contrary contained herein, (x) in
the event that there are accrued but unpaid cash dividends with respect to any
Senior Preferred Stock at the date of the closing of a Qualified Public
Offering, all such accrued but unpaid cash dividends payable to the holders of
Senior Preferred Stock shall be canceled, and no holder or former holder of
Senior Preferred Stock shall have any further right or interest to such
dividends, or (y) in the event of voluntary conversion by a holder of any Senior
Preferred Stock at a time when the Corporation is contemplating an initial
public offering, the Corporation may, at its option, defer payment of any
dividends otherwise payable upon such conversion for up to 180 days and if a
Qualified Public Offering is closed within such 180 day period, all of such
accrued but unpaid cash dividends payable to such holders of Senior Preferred
Stock shall be canceled and no such holder of Senior Preferred Stock shall have
any further right or interest therein.

              (ii)   Procedure for Mandatory Conversion. Upon a mandatory
conversion pursuant to Article IV.C.6(j)(i), the outstanding shares of Senior
Preferred Stock will be automatically converted into shares of Common Stock
without any further action by the holders of such shares and whether or not the
certificates representing such shares are surrendered for conversion to the
Corporation or the transfer agent for the Senior Preferred Stock. On the date of
mandatory conversion, all rights with respect to the Senior Preferred Stock so
converted, including the rights, if any, to receive notices and vote, will
terminate, except for the rights of the holders thereof, upon surrender of their
certificate or certificates therefor, to receive certificates for the number of
shares of Common Stock into which such Senior Preferred Stock has been converted
(as rounded with respect to any fraction of a share as provided in Article
IV.C.6(b)(i)). If so required by the Corporation, certificates surrendered for
conversion shall be endorsed or accompanied by written instrument or instruments
of transfer, in form satisfactory to the Corporation, duly authorized in
writing. As soon as practicable after the date of such mandatory conversion and
the surrender of the certificate or certificates of Senior Preferred Stock, the
Corporation shall cause to be issued and delivered to such holder, or on his,
her or its written order, a certificate or certificates for the number of full
shares of Common Stock issuable on such conversion in accordance with the
provisions hereof as rounded as provided in Article IV.C.6(b)(i) in respect of
any fraction of a share of Common Stock otherwise issuable upon such conversion.

       (k)    Retirement and Cancellation of Shares. All certificates evidencing
shares of Senior Preferred Stock which are required to be surrendered for
conversion in accordance with the provisions hereof shall, from and after the
date such certificates are so required to be surrendered, be deemed to have been
retired and canceled and the shares of Senior Preferred


                                     - 44 -
<PAGE>   45


Stock represented thereby converted into Common Stock for all purposes,
notwithstanding the failure of the holder or holders thereof to surrender such
certificates on or prior to such date.

       7.     Voting Rights. (a) Each holder of shares of Senior Preferred Stock
shall be entitled to the number of votes equal to the number of shares of Common
Stock into which such shares of Senior Preferred Stock could be converted and
shall have voting rights and powers equal to the voting rights and powers of the
Common Stock (except as otherwise expressly provided herein or as required by
law, voting together with the Common Stock and other series of Preferred Stock
as a single class) and shall be entitled to notice of any stockholders' meeting
in accordance with applicable law and the Bylaws of the Corporation.

       (b)    So long as any shares of Senior Preferred Stock remain
outstanding, the Corporation shall not, without the vote or written consent by

voting together as a separate single class on the basis of one vote for each
share of Series E Preferred Stock, Series F Preferred Stock and Series G

the assets of the Corporation;

of Control which is treated as a liquidation pursuant to Article IV.C.4(e)) or
winding up of the Corporation;

              (v)    Any transaction pursuant to which the Corporation or any of
its subsidiaries: (w) acquires the capital stock of any entity other than the
Corporation, or any entity which is not then a subsidiary of the Corporation,
pursuant to a solicitation of tenders therefor, or in one or more negotiated
block, market or other transactions not involving a tender offer, or a
combination of any of the foregoing; (x) makes any entity a subsidiary of the
Corporation; (y) causes any entity to be merged into the Corporation or any of
its subsidiaries, in any case, pursuant to a merger, purchase of assets or any
reorganization providing for the delivery or issuance to the holders of such
entity's then outstanding securities, in exchange for such securities, cash or
securities of the Corporation or any of its affiliates, or a combination
thereof; or (z) purchases all or substantially all of the business or assets of
any entity; or

              (vi)   The repurchase, redemption or other acquisition of any
shares of Preferred Stock or Common Stock other than (x) repurchases of shares
of capital stock pursuant to

of any other capital stock of the Corporation;

              (ii)   Reduce the amount payable to the holders of the Senior

benefit of Series F Preferred Stock and Series G Preferred Stock in a

F Preferred


                                     - 49 -
<PAGE>   50


Stock (including for this purpose Series E Preferred Stock issuable upon the
exercise of the Series E Preferred Stock Purchase Warrant issued on the Original
Issue Date) and the Series G Preferred Stock shall have the pre-emptive right to
purchase, on a pro rata basis, all or any part of New Securities (as defined in
Article IV.B.5) which the Corporation may, from time to time, propose to issue
and sell, as and to the same extent as holders of the Collective Preferred Stock
under Article IV.B.5; except that holders of Series G Preferred Stock shall not
have pre-emptive rights to purchase up to 230,769,231 shares of Series G
Preferred Stock issued by the Corporation on or after the date on which the
Sixth Amended and Restated Certificate of Incorporation is filed. The pro rata
share of each holder of such Series E Preferred Stock, Series F Preferred Stock
or Series G Preferred Stock, for purposes of this pre-emptive right to purchase,
shall be determined by dividing (x) the total number of shares of Common Stock
which are owned by such holder plus the total number of shares of Common Stock
issuable upon conversion of such Series E Preferred Stock, Series F Preferred
Stock or Series G Preferred Stock owned by such holder of such Series E
Preferred Stock, Series F Preferred Stock or Series G Preferred Stock, by (y)
the total number of shares of Common Stock then outstanding plus the total
number of shares of Common Stock issuable upon conversion of all then
outstanding Company Preferred Stock. All of the foregoing notwithstanding, in
the event any holder of Series E Preferred Stock, Series F Preferred Stock or
Series G Preferred Stock also owns Common Stock and any Collective Preferred
Stock, the Common Stock which is owned by such holder shall not be counted for
purposes of clause (x) of the immediately preceding sentence.

       (b)    Waiver. The pre-emptive right to purchase set forth in Article
IV.C.9(a) may be waived in writing by the holders of (i) sixty percent (60%) of
the voting power of the then outstanding Series E Preferred Stock and Series G
Preferred Stock, voting together as a separate single class on the basis of one
vote for each share of Series E Preferred Stock then outstanding, and (ii)
sixty-six and two thirds percent (66-2/3%) of the voting power of the then
outstanding Series F Preferred Stock, voting as a separate single class on the
basis of one vote for each share of Series F Preferred Stock then outstanding.

       (c)    Expiration. The pre-emptive rights described in this Article
IV.C.9 shall expire upon the closing of a Qualified Public Offering.

       10.    No Reissuance of Senior Preferred Stock. No share or shares of
Senior Preferred Stock acquired by the Corporation by reason of purchase,
conversion or otherwise shall be reissued, and all such shares shall be
canceled, retired and eliminated from the shares that the Corporation shall be
authorized to issue.

       D.     RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS OF POST-IPO
COMMON SHARES. Except as otherwise expressly provided in this ARTICLE IV.D., all
Post-IPO Common Shares shall be identical and shall entitle the holders thereof
to the same rights and privileges.

       1.     Dividends. When, as and if dividends on Post-IPO Common Shares are
declared by the Corporation's Board of Directors, whether payable in cash, in
property or in securities of the Corporation, the holders of Post-IPO Common
Shares shall be entitled to share equally in and


                                     - 50 -
<PAGE>   51


to receive, in accordance with the number of Post-IPO Common Shares held by each
such holder, all such dividends.

       Dividends payable under this Article IV.D. shall be paid to the holders
of record of the outstanding Post-IPO Common Shares as their names shall appear
on the stock register of the Corporation on the record date fixed by the Board
of Directors of the Corporation in advance of declaration and payment of each
dividend. Any dividends paid in shares shall be paid in Post-IPO Common Shares.
Any Post-IPO Common Shares issued as a dividend pursuant to this Article IV.D.
shall, when so issued, be duly authorized, validly issued, fully paid and
non-assessable and free of all liens and charges. The Corporation shall not
issue fractions of Post-IPO Common Shares on payment of such dividend but shall
issue a whole number of shares to such holder of Post-IPO Common Shares rounded
up or down in the Corporation's sole discretion to the nearest whole number,
without compensation to the stockholder whose fractional share has been rounded
down or from any stockholder whose fractional share has been rounded up.

       Notwithstanding anything contained herein to the contrary, no dividends
on Post-IPO Common Shares shall be declared by the Corporation's Board of
Directors or paid or set apart for payment by the Corporation at any time that
such declaration, payment, or setting apart is prohibited by applicable law.

       2.     Stock Split, Reclassification, etc. The Corporation shall not in
any manner subdivide (by any stock split, reclassification, stock dividend,
recapitalization or otherwise) or combine the outstanding shares of one class of
Post-IPO Common Shares unless the outstanding shares of all classes of Post-IPO
Common Shares shall be proportionately subdivided or combined.

       3.     Liquidation. Upon any voluntary or involuntary liquidation,
dissolution or winding-up of the affairs of the Corporation, after payment shall
have been made to holders of outstanding Post-IPO Preferred Shares, if any, of
the full amount of which they are entitled pursuant to this Sixth Amended and
Restated Certificate of Incorporation and any resolutions that may be adopted
from time to time by the Corporation's Board of Directors, in accordance with
Article IV.E. below (for the purpose of fixing the voting rights, designations,
preferences and relative participating, optional or other special rights of any
class or series of Post-IPO Preferred Shares), the holders of Post-IPO Common
Shares shall be entitled, to the exclusion of the holders of Post-IPO Preferred
Shares, if any, to share ratably, in accordance with the number of Post-IPO
Common Shares held by each such holder, in all remaining assets of the
Corporation available for distribution among the holders of Post-IPO Common
Shares, whether such assets are capital, surplus, or earnings. For the purposes
of this Article IV.D., neither the consolidation or merger of the Corporation
with or into any other corporation or corporations in which the stockholders of
the Corporation receive capital stock and/or other securities (including debt
securities) of the acquiring corporation (or of the direct or indirect parent
corporation of the acquiring corporation), nor the sale, lease or transfer by
the Corporation of all or any part of its assets, nor the reduction of the
capital stock of the Corporation, shall be deemed to be a voluntary or
involuntary liquidation, dissolution, or winding-up of the Corporation as those
terms

are used in this Article IV.D..

       4.     Voting. Each holder of Post-IPO Common Shares shall be entitled to
one vote for each share of such stock issued and outstanding and registered in
such holder's name and shall be entitled to vote upon such matters and in such
manner as may be provided by Delaware law and this Sixth Amended and Restated
Certificate of Incorporation.

       5.     No Pre-emptive or Subscription Rights. No holder of Post-IPO
Common Shares shall be entitled to pre-emptive or subscription rights.

       E.     RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS OF POST-IPO
PREFERRED SHARES. Shares of Post-IPO Preferred Shares may be issued from time to
time in one or more series as may be determined by the Board of Directors of the
Corporation. Subject to the provisions of this Sixth Amended and Restated
Certificate of Incorporation and this Article IV.E, the Board of Directors of
the Corporation is authorized to determine or alter the rights, preferences,
privileges and restrictions granted to or imposed upon any wholly unissued class
or series of Post-IPO Preferred Shares and, within the limits and restrictions
stated in any resolution or resolutions of the Board of Directors of the
Corporation originally fixing the number of shares constituting any such
additional series, to increase or decrease (but not below the number of shares
of such series then outstanding) the number of shares of any such additional
series subsequent to the issue of shares of that series.

       Authorized and unissued shares of Post-IPO Preferred Shares may be issued
with such designations, voting powers, preferences and relative participating
optional or other special rights, and qualifications, limitations and
restrictions on such rights, as the Board of Directors of the Corporation may
authorize by resolutions duly adopted prior to the issuance of any shares of any
class or series of Post-IPO Preferred Shares, including, but not limited to: (i)
the distinctive designation of each series and the number of shares that will
constitute such series; (ii) the voting rights, if any, of shares of such series
and whether the shares of any such series having voting rights shall have
multiple votes per share; (iii) the dividend rate on the shares of such series,
any restriction, limitation or condition upon the payment of such dividends,
whether dividends shall be cumulative and the dates on which dividends are
payable; (iv) the prices at which, and the terms and conditions on which, the
shares of such series may be redeemed, if such shares are redeemable; (v) the
purchase or sinking fund provisions, if any, for the purchase or redemption of
shares of such series; (vi) any preferential amount payable upon shares of such
series in the event of the liquidation, dissolution or winding-up of the Company
or the distribution of its assets; and (vii) the prices or rates of conversion
at which, and the terms and conditions on which, the shares are convertible.

       Any and all Post-IPO Preferred Shares issued and for which full
consideration has been paid or delivered shall be deemed fully paid stock and
the holder thereof shall not be liable for any further payment thereon.

                                    ARTICLE V


                                     - 52 -
<PAGE>   53


       The Board of Directors shall have the power, in addition to the
stockholders, to make, repeal, alter, amend and rescind any or all of the bylaws
of the Corporation.

                                   ARTICLE VI

       Subject to Article IV.C.8 hereof, the Board of Directors of the
Corporation shall have no more than nine (9) members; provided, however, that
upon the closing of a Qualified Public Offering, the Board of Directors shall be
constituted as follows:

       (i)    The number of directors which will constitute the whole Board of
Directors of the Corporation shall be fixed exclusively by one or more
resolutions adopted by the Board of Directors of the Corporation or as otherwise
provided in the By-Laws of the Corporation.

       (ii)   As soon as practicable following the closing of a Qualified Public
Offering, the directors shall be divided into three classes, as nearly equal in
number as possible, designated as Class I, Class II, and Class III,
respectively, and assigned to such classes in accordance with a resolution or
resolutions adopted by the Board of Directors. At the first annual meeting of
stockholders following the closing of a Qualified Public Offering, (i) the Class
I directors shall be nominated for election for a full term of three years, (ii)
the Class II directors shall be nominated for election for a term of two years,
and (iii) the Class III directors shall be nominated for election for a term of
one year. 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.

       (iii)  Notwithstanding the foregoing provisions of this ARTICLE VI, each
director shall serve until his successor is duly elected and qualified or until
his death, resignation or removal. Neither the Board of Directors nor any
individual director may be removed without cause. 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. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

       (iv)   In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors shall have the power to make, adopt, amend or
repeal the Bylaws, or adopt new Bylaws for this Corporation, by a resolution
adopted by a majority of the directors.

       (v)    Vacancies in the Board of Directors may be filled by a majority of
the remaining directors, though less than a quorum, or by a sole remaining
director.

       (vi)   Elections of directors need not be by written ballot unless the
bylaws of the Corporation shall so provide.

                                   ARTICLE VII

       Meetings of stockholders may be held within or without the State of
Delaware, as the


                                     - 53 -
<PAGE>   54


bylaws may provide. The books of the Corporation may be kept (subject to any
provision contained in the General Corporation Law of Delaware) outside the
State of Delaware at such place or places as may be designated from time to time
by the Board of Directors or in the bylaws of the Corporation.

                                  ARTICLE VIII

       A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of Title 8 of the General Corporation
Law of Delaware, or (iv) for any transaction from which the director derived any
improper personal benefit. The foregoing sentence notwithstanding, if the
General Corporation Law of Delaware is hereafter amended to authorize further
limitations of the liability of a director of a corporation, then a director of
the Corporation, in addition to the circumstances in which a director is not
personally liable set forth in the preceding sentence, shall not be liable to
the fullest extent permitted by the General Corporation Law of Delaware as so
amended. Any repeal or modification of the foregoing provisions of this Article
VIII by the stockholders of the Corporation shall not adversely affect any right
or protection of a director of the Corporation existing at the time of such
repeal or modification.

                                   ARTICLE IX

       The Corporation shall indemnify and hold harmless any director and
officer of the Corporation from and against any and all expenses and liabilities
that may be imposed upon or incurred by such person in connection with, or as a
result of, any proceeding in which such person may become involved, as a party
or otherwise, by reason of the fact that such person is or was such a director
or officer of the Corporation, whether or not such person continues to be such
at the time such expenses and liabilities shall have been imposed or incurred.
It is the intention of this Article IX to provide indemnification to the fullest
extent permitted by the laws of the State of Delaware, as they may be amended
from time to time.

                                    ARTICLE X

       Subject to the provisions contained herein, the Corporation reserves the
right to amend, alter, change or repeal any provision contained in this Sixth
Amended and Restated Certificate of Incorporation, in the manner now or
hereafter prescribed by statute, and all rights conferred upon stockholders
herein are granted subject to this reservation.

       This Sixth Amended and Restated Certificate of Incorporation was duly
adopted, and written consent has been given, in accordance with the provisions
of Sections 242 and 228 (with notice having been given in accordance therewith)
of the General Corporation Law of the State of Delaware.

                                   ARTICLE 1.

special meeting the stockholders may elect the directors and transact other
business with the same force and effect as at an annual meeting duly called and

            (d) At an annual meeting of the stockholders of the Corporation,
only such business shall be conducted as shall have been properly brought before

in writing to the Secretary of the Corporation. To be timely, such stockholder's
notice must be delivered in writing either by personal delivery or by registered
or certified mail, return receipt requested, to the principal executive offices
of the Corporation (addressed to the Secretary) not less than one hundred twenty
(120) calendar days prior to the anniversary date of the release of the

calendar days from the anniversary of the annual meeting of its stockholders
stated in the previous year's proxy statement, a proposal of a stockholder shall
be received by the Corporation a reasonable time before the solicitation is

anything in the Bylaws of the Corporation to the contrary, no business shall be
conducted at an annual meeting except in accordance with the procedures set
forth in this Section 2.02. The Chairman of an annual meeting may refuse to
acknowledge a motion to consider any business that he/she determines was not
made in compliance with the foregoing procedures and if he/she should so
determine and declare to such meeting, then any such business not properly
brought before such meeting shall not be transacted.

            (e) Only persons who are nominated in accordance with the procedures
set forth in this Section 2.02, shall be eligible for election as directors.
Without limiting the foregoing, nomination of persons for election to the Board
of Directors may be made at a meeting of stockholders (i) by or at the direction

Directors or any nominating or similar committee thereof, shall be made pursuant
to timely notice in writing to the Secretary of the Corporation. To be timely, a
stockholder's notice shall be delivered in writing either by personal delivery
or by registered or certified mail, return receipt requested, to the principal
executive offices of the Corporation (addressed to the Secretary) not less than
one hundred twenty (120) calendar days prior to the anniversary date of the
release of the Corporation's proxy statement to its stockholders in connection
with the preceding year's annual meeting of its stockholders, except that if no
annual meeting of its stockholders was held in the previous year or the date of
the annual meeting of its stockholders has been changed by more than sixty (60)
calendar days from the anniversary of the annual meeting of its stockholders
stated in the previous year's proxy statement, a proposal of a stockholder shall
be received by the Corporation a reasonable time before the solicitation is
made. Such stockholder's notice shall set forth (i) as to each person whom such
stockholder proposes to nominate for election or re-election as a director (A)
the name, age, business address and residence address of such nominee, (B) the
principal occupation or employment of such nominee, (C) the class and number of
shares of the Corporation, if any, which are beneficially owned by such nominee,
(D) a description of all arrangements or understandings between such stockholder
and each nominee and any other person or persons (naming such person or persons)
pursuant to which such nomination is made by such stockholder, and (E) any other
information relating to such nominee that is required to be disclosed in
solicitations of proxies for election of directors, or as otherwise required, in
each case, pursuant to Regulation 14A under the Securities Exchange Act of 1934,
as amended (including, without limitation, such nominee's written consent to
being named in the proxy statement as a nominee and to serving as a director of
the Corporation if elected); and (ii) as to such stockholder (A) the name and
address, as they appear on the Corporation's books, of such stockholder, (B) a
representation that such stockholder is a holder of record of stock of the
Corporation entitled to vote at such meeting and that such stockholder intends
to appear in person or by proxy at such meeting to nominate the person or
persons specified in such notice, and (C) the class and number of shares of
stock of the Corporation which are beneficially owned by such stockholder. At
the request of the Board of Directors, any person nominated by the Board of
Directors for election as a director of the Corporation shall furnish to the
Secretary of the Corporation that information required to be set forth in a
stockholder's notice of nomination, as provided above in this clause (e), which
pertains to such nominee. No person shall be eligible for election as a director
of the Corporation unless nominated in accordance with the procedures set forth
in this Section 2.02. The chairman of the meeting may refuse to acknowledge a
motion to consider any nominee as a director that he/she determines was not made
in compliance with the foregoing procedures and if he/she should so determine
and declare to such meeting, then the defective nomination shall be disregarded.

            SECTION 2.03. Special Meetings. A special meeting of the
stockholders for any purpose or purposes may be called at any time by the
Chairman of the Board, the President or by order of the Board of Directors and

special meeting, shall state briefly the purposes thereof.

            (b) Notice of any meeting of stockholders shall not be required to
be given to any stockholder who shall attend such meeting in person or by proxy
or who shall in person or by attorney thereunto authorized, waive such notice in
writing or by telegraph, cable or any other available method either before or
after such meeting. Notice of any adjourned meeting of the stockholders shall
not be required to be given except when expressly required by law.

            SECTION 2.05. Quorum.

            (a) At each meeting of the stockholders, except where otherwise
provided by statute, the Certificate of Incorporation of the Corporation (the
"Certificate of Incorporation") or these By-Laws, the holders of record of a
majority of the issued and outstanding shares of stock of the Corporation
entitled to vote at such meeting, present in person or represented by proxy,

            (b) In the absence of a quorum, a majority in interest of the
stockholders of the Corporation entitled to vote, present in person or
represented by proxy or, in the absence of all such stockholders, any officer
entitled to preside at, or act as secretary of, such meeting, shall have the
power to adjourn the meeting from time to time, until stockholders holding the
requisite amount of stock shall be present or represented. At any such adjourned
meeting at which a quorum shall be present any business may be transacted which
might have been transacted at the meeting as originally called.

            SECTION 2.06. Organization. At each meeting of the stockholders, the
Chairman of the Board, or in his or her absence, the President, any Vice
President, or any other officer designated by the Board of Directors, shall act

in the absence of the Secretary and all Assistant Secretaries, a person whom the
chairman of such meeting shall appoint shall act as secretary of the meeting and
keep the minutes thereof.

            SECTION 2.07. Voting.

            (a) Except as otherwise provided by law or by the Certificate of
Incorporation or these By-Laws, at every meeting of the stockholders each

registered in his or her name on the books of the Corporation:

                      (i)  on the date fixed pursuant to Section 9.03 of these
            By-Laws as the record date for the determination of stockholders
            entitled to vote at such meeting; or

                      (ii) if no such record date shall have been fixed, then
            the record date shall be at the close of business on the day next
            preceding the day on which notice of such meeting is given.

            (b) Persons holding stock in a fiduciary capacity shall be entitled
to vote the shares so held. In the case of stock held jointly by two or more
executors, administrators, guardians, conservators, trustees or other
fiduciaries, such fiduciaries may designate in writing one or more of their
number to represent such stock and vote the shares so held, unless there is a
provision to the contrary in the instrument, if any, defining their powers and
duties.

            (c) Persons whose stock is pledged shall be entitled to vote thereon
until such stock is transferred on the books of the Corporation to the pledgee,
and thereafter only the pledgee shall be entitled to vote.

            (d) Any stockholder entitled to vote may do so in person or by his
or her proxy appointed by an instrument in writing subscribed by such
stockholder or by his or her attorney thereunto authorized, or by a telegram,
cable or any other available method delivered to the secretary of the meeting;
provided, however, that no proxy shall be voted after three years from its date,
unless said proxy provides for a longer period.

            (e) At all meetings of the stockholders, all matters (except where
other provision is made by law or by the Certificate of Incorporation or these
By-Laws) shall be decided by the vote of a majority in interest of the
stockholders entitled to vote thereon, present in person or by proxy, at such
meeting, a quorum being present. The vote upon any matter, including the
election of directors, need not be by written ballot.

            SECTION 2.08. Inspectors. The chairman of the meeting may at any
time appoint one or more inspectors to serve at a meeting of the stockholders.
Such inspectors shall decide upon the qualifications of voters, accept and count
the votes for and against the questions presented, report the results of such
votes, and subscribe and deliver to the secretary of the meeting a certificate
stating the number of shares of stock issued and outstanding and entitled to
vote thereon and the number of shares voted for and against the questions
presented. The inspectors need not be stockholders of the Corporation, and any
director or officer of the Corporation may be an inspector on any question other
than a vote for or against his or her election to any position with the
Corporation or on any other question in which he or she may be directly
interested. Before acting as herein provided, each inspector shall subscribe an
oath faithfully to execute the duties of an inspector with strict impartiality
and according to the best of his or her ability.

cause to be prepared and made, at least ten days before every meeting of the
stockholders, a complete list of the stockholders entitled to vote thereat,

which place shall be specified in the notice of the meeting or, if not so
specified, at the place where the meeting is to be held.

            (b) Such list shall be produced and kept at the time and place of
the meeting during the whole time thereof and may be inspected by any
stockholder who is present.

            (c) The stock ledger shall be conclusive evidence as to who are the
stockholders entitled to examine the stock ledger and the list of stockholders
required by this Section 2.09 on the books of the Corporation or to vote in

                               BOARD OF DIRECTORS

            SECTION 3.01. General Powers. The business, property and affairs of
the Corporation shall be managed by the Board of Directors.

            SECTION 3.02. Number, Qualifications, Terms and Removal from Office.

            (a) The number of directors of the Corporation on the date of
adoption of these Bylaws shall be nine (9); provided, however, that upon the
closing of a Qualified Public Offering (as defined in the Certificate of
Incorporation), the number of directors of the Corporation shall be as set forth
in one or more resolutions adopted by the Board of Directors of the Corporation
and the directors shall be divided into three classes, as nearly equal in number
as possible, designated as Class I, Class II, and Class III, respectively, and
assigned to such classes in accordance with a resolution or resolutions adopted
by the Board of Directors. At the first annual meeting of stockholders following
the closing of a Qualified Public Offering, (i) the Class I directors shall be
nominated for election for a full term of three years, (ii) the Class II
directors shall be nominated for election for a term of two years, and (iii) the
Class III directors shall be nominated for election for a term of one year. 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. The number of directors of the Corporation may be
increased or decreased by resolution of the Board of Directors of the
Corporation. All directors of the Corporation shall hold office for the term for
which they are elected or until their successors shall have been elected and
qualified, whichever period is longer. The directors of the Corporation need not
be residents of the State of Delaware.

            (b) A director need not be a stockholder.


            (c) Except as otherwise contemplated by the Certificate of
Incorporation, vacancies and newly created directorships resulting from any
increase in the authorized number of directors may be filled by a majority of
the directors then in office, though less than a quorum, or by a sole remaining
director, and the directors so chosen shall hold office until the next annual
election and until their successors are duly elected and shall qualify, unless
sooner displaced. If there are no directors in office, then an election of
directors may be held in the manner provided by statute. Except as otherwise
contemplated by the Certificate of Incorporation, whenever the holders of any
class or classes of stock or series thereof are entitled to elect one or more
directors by the provisions of the Certificate of Incorporation, vacancies and
newly created directorships of such class or classes or series may be filled by
a majority of the directors elected by such class or classes or series thereof
then in office, or by a sole remaining director so elected. 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 Court of Chancery may, upon
application of any stockholder or stockholders holding at least ten percent of
the total number of the shares at the time outstanding, on a common equivalent
basis, 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 office.


            SECTION 3.03. Quorum and Manner of Acting.

            (a) Except as otherwise provided by statute or by the Certificate of
Incorporation, a majority of the directors at the time in office shall
constitute a quorum for the transaction of business at any meeting and the
affirmative action of a majority of the directors present at any meeting at
which a quorum is present shall be required for the taking of any action by the
Board of Directors.

            (b) In the event one or more of the directors shall be disqualified
to vote at such meeting, then the required quorum shall be reduced by one for
each such director so disqualified; provided, however, that in no event shall
the quorum as adjusted be less than one third of the total number of directors.

            (c) In the absence of a quorum at any meeting of the Board such
meeting need not be held; or a majority of the directors present thereat or, if
no director be present, the Secretary may adjourn such meeting from time to time
until a quorum shall be present. Notice of any adjourned meeting need not be
given.

            SECTION 3.04. Offices, Place of Meeting and Records. The Board of

time to time by resolution determine. If any day fixed for a regular meeting
shall be a legal holiday at the place where the meeting is to be held, then the
meeting which would otherwise be held on that day shall be held at said place at
the same hour on the next succeeding business day. Notice of regular meetings
need not be given.

            SECTION 3.07. Special Meetings; Notice. Special meetings of the
Board of Directors shall be held whenever called by the Chairman of the Board,
the President or by any two (2) of the directors. Notice of each such meeting
shall be mailed to each director, addressed to him or her at his or her
residence or usual place of business, at least two days before the day on which
the meeting is to be held, or shall be sent to him or her at his or her
residence or at such place of business by telegraph, cable or other available
means, or shall be delivered personally or by telephone, not later than one day
before the day on which the meeting is to be held. Each such notice shall state
the time and place of the meeting but need not state the purposes thereof except
as otherwise herein expressly provided. Notice of any such meeting need not be
given to any director, however, if waived by him or her in writing or by
telegraph, cable or otherwise, whether before or after such meeting shall be
held, or if he or she shall be present at such meeting.

            SECTION 3.08. Organization. At each meeting of the Board of

Board of Directors, the Chairman of the Board, the President, any Vice President
or the Secretary of the Corporation. Such resignation shall take effect at the
date of receipt of such notice or at any later time specified therein; and,
unless otherwise specified therein, the acceptance of such resignation shall not
be necessary to make it effective.

serving as such, who is neither an employee of nor a compensated consultant to
the Corporation, shall be entitled to receive from the Corporation such amount
per annum or such fees for attendance at directors' meetings, or both, as the
Board of Directors shall from time to time determine. Each director shall be

                   INDEMNIFICATION OF DIRECTORS, OFFICERS AND
                        OTHER AUTHORIZED REPRESENTATIVES

            SECTION 7.01. Indemnification of Authorized Representatives in Third
Party Proceedings. The Corporation shall indemnify any person who was or is an
authorized representative of the Corporation, and who was or is a party, or is
threatened to be made a party to any third party proceeding, by reason of the
fact that such person was or is an authorized representative of the Corporation,
against expenses, judgments, penalties, fines and amounts paid in settlement
actually and reasonably incurred by such person in connection with such third
party proceeding if such person acted in good faith and in a manner such person
reasonably believed to be in, or not opposed to, the best interests of the
Corporation and, with respect to any criminal third party proceeding, had no
reasonable cause to believe such conduct was unlawful. The termination of any
third party proceeding by judgment, order, settlement, indictment, conviction or
upon a plea of nolo contendere or its equivalent, shall not of itself create a
presumption that the authorized representative did not act in good faith and in
a manner which such person reasonably believed to be in or not opposed to, the
best interests of the Corporation, and, with


                                      -14-
<PAGE>   15

respect to any criminal third party proceeding, had reasonable cause to believe
that such conduct was unlawful.

            SECTION 7.02. Indemnification of Authorized Representatives in
Corporate Proceedings. The Corporation shall indemnify any person who was or is
an authorized representative of the Corporation and who was or is a party or is
threatened to be made a party to any corporate proceeding, by reason of the fact
that such person was or is an authorized representative of the Corporation,
against expenses actually and reasonably incurred by such person in connection
with the defense or settlement of such corporate action if such person acted in
good faith and in a manner reasonably believed to be in, or not opposed to, the
best interests of the Corporation, except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery or the court in which such corporate proceeding was pending
shall determine upon application that, despite the adjudication or liability but
in view of all the circumstances of the case, such authorized representative is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery or such other court shall deem proper.

            SECTION 7.03. Mandatory Indemnification of Authorized
Representatives. To the extent that an authorized representative of the
Corporation has been successful on the merits or otherwise in defense of any
third party or corporate proceeding or in defense of any claim, issue or matter
therein, such person shall be indemnified against expenses actually and
reasonably incurred by such person in connection therewith.

            SECTION 7.04. Determination of Entitlement to Indemnification. Any
indemnification under Section 7.01, 7.02 or 7.03 of this Article (unless ordered
by a court) shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the authorized representative
is proper in the circumstances because such person has either met the applicable
standard of conduct set forth in Section 7.01 or 7.02 or has been successful on
the merits or otherwise as set forth in Section 7.03 and that the amount
requested has been actually and reasonably incurred. Such determination shall be
made:

            (a) By the Board of Directors by a majority of a quorum consisting
of directors who were not parties to such third party or corporate proceeding,
or

            (b) If such a quorum is not obtainable, or, even if obtainable, a
majority vote of such a quorum so directs, by independent legal counsel in a
written opinion, or

            (c) By the stockholders.

            SECTION 7.05. Advancing Expenses. Expenses actually and reasonably
incurred in defending a third party or corporate proceeding may be paid on
behalf of an authorized representative by the Corporation in advance of the
final disposition of such third party or corporate proceeding upon receipt of an
undertaking by or on behalf of such authorized representative to repay such
amount if it shall ultimately be determined that such person is not


                                      -15-
<PAGE>   16

entitled to be indemnified by the Corporation as authorized in this Article. The

employed shall be deposited from time to time to the credit of the Corporation
in such banks, trust companies or other depositaries as the Board of Directors
or Executive Committee or other committee designated by the Board so to act may
from time to time designate, or as may be designated by any officer or officers

Board of Directors or Executive Committee or other committee designated by the

meetings of the holders of the stock or other securities of such other
corporation, association or trust, or to consent in writing, in the name of the
Corporation as such holder, to any action by such other corporation, association
or trust, and may instruct the person or persons so appointed as to the manner
of casting such votes or giving such consent, and may execute or cause to be
executed in the name and on behalf of the Corporation and under its corporate

shall cease to be such officer or officers of the Corporation, whether because
of death, resignation or otherwise, before such certificate or certificates
shall have been delivered by the Corporation, such certificate or certificates

                    SECOND AMENDED AND RESTATED SHAREHOLDERS'
                        AND REGISTRATION RIGHTS AGREEMENT

This FIRST AMENDMENT TO SECOND AMENDED AND RESTATED SHAREHOLDERS' AND
REGISTRATION RIGHTS AGREEMENT (this "First Amendment"), which amends the SECOND
AMENDED AND RESTATED SHAREHOLDERS' AND REGISTRATION RIGHTS AGREEMENT (the
"Second Amended and Restated Agreement") dated as of April 16, 1997 by and among
AirNet Communications Corporation, a Delaware corporation (the "Company"), and
the shareholders whose signatures appear on the signature pages thereto (the
shareholders are collectively referred to as the "Shareholders" and individually
as a "Shareholder") is made as of September 20, 1999 by and among the Company
and the Shareholders.

                                   WITNESSETH:

WHEREAS, the Company is contemplating an initial public offering of shares of
its authorized but unissued common stock, in accordance with the terms of a
registration statement to be filed with the Securities and Exchange Commission;
and

WHEREAS, the Company and the Shareholders desire to amend the Second Amended and
Restated Agreement in accordance with Section 9.2 thereof to clarify certain
provisions relating to piggyback registration rights.

NOW, THEREFORE, intending to be legally bound, the parties hereto agree that the
Second Amended and Restated Agreement is hereby amended as follows:

       1.    Section 4.4(a) of the Second Amended and Restated Agreement is
hereby amended and restated in its entirety as follows:

             "4.4   (a)    Whenever the Company proposes to file a Registration
Statement (other than by a registration pursuant to Section 4.3, a registration
pursuant to the Company's Initial Public Offering, a registration statement on
Form S-3 that is automatically declared effective, or a registration statement
on Form S-4 or S-8 or their successors, or any registration statement covering
only securities proposed to be issued in exchange for securities or assets of
another corporation) at any time and from time to time, it will, prior to such
filing, give written notice to all Holders of its intention to do so and, upon
the written request of a Holder or Holders given within twenty (20) business
days after the Company provides such notice, the Company shall use its best
efforts to cause all Registrable Shares which the Company has been requested by
such Holder or Holders to register to be registered under the Act to the extent
necessary to


                                       1
<PAGE>   2

permit their sale or other disposition in accordance with the intended methods
of distribution specified in the request of such Holder or Holders; provided
that the Company shall have the right to postpone or withdraw any registration
effected pursuant to this Section 4.4 without obligation to any Holder."

       2.    Section 4.4(b) of the Second Amended and Restated Agreement is
hereby amended and restated in its entirety as follows:

                           "(b) In connection with any offering under this
Section 4.4 involving an underwriting, the Company shall not be required to
include any Registrable Shares in such underwriting unless the Holders thereof
accept the terms of the underwriting as agreed upon between the Company and the
underwriters selected by it, and then only in such quantity as will not, in the
opinion of the underwriters, jeopardize the success of the offering by the
Company; provided, that if in the opinion of the underwriters the inclusion of
any Registrable Shares in such underwriting would jeopardize the success of the
offering by the Company, the Company will not be required to include any
Registrable Shares in such underwriting. If in the opinion of the managing
underwriter the registration of all, or part of, the Registrable Shares which
the Holders have requested to be included would materially and adversely affect
such public offering, then the Company shall be required to include in the
underwriting only that number of Registrable Shares, if any, which the managing
underwriter believes may be sold without causing such adverse effect. If the
number of Registrable Shares to be included in the underwriting in accordance
with the foregoing is less than the total number of shares which the Holders of
Registrable Shares have requested to be included, then the Company may include
all securities proposed to be registered by the Company to be sold for its own
account and the Holders of Registrable Shares who have requested registration
shall participate, along with other holders of shares to be included pursuant to
other registration rights granted by the Company, in the underwriting as
follows: if after including in the Registration the securities proposed by the
Company to be sold for its own account, the number of shares proposed for
Registration by Holders pursuant to Section 4.4 must be limited in order to
avoid exceeding the managing underwriter's limit, the securities proposed by any
director or executive officer of the Company ("Key Management") to be sold for
his/her own account shall be reduced (including the elimination of all such
securities from the Registration, if necessary) such that such Registration does
not exceed the managing underwriter's limit. If after reducing the number of
securities proposed by any member of Key Management to be sold for his/her own
account to zero, it is necessary to limit the shares proposed for Registration
by other Holders who have requested Registration, the limitation on the number
of shares proposed for Registration by such other Holders shall be applied on a
pro rata basis based upon their total ownership of Registrable Shares and the
total ownership of registrable shares of Common Stock of the Company by such
other holders. If any Holder would thus be entitled to include more shares than
such Holder requested to be registered, the excess shall be allocated among
other requesting Holders pro rata based upon their total ownership of
Registrable Shares."

       3     This First Amendment may be executed in any number of counterparts
with the same effect as if all signatory parties had signed the same document.
All counterparts shall be construed together and shall constitute one and the
same instrument.

                                 FIRST AMENDMENT
                                       TO
                      SECOND AMENDED AND RESTATED AGREEMENT
          AMONG SERIES E, SERIES F AND SERIES G PREFERRED STOCKHOLDERS
                    AND SENIOR REGISTRATION RIGHTS AGREEMENT

This FIRST AMENDMENT TO SECOND AMENDED AND RESTATED AGREEMENT AMONG SERIES E,
SERIES F AND SERIES G PREFERRED STOCKHOLDERS AND SENIOR REGISTRATION RIGHTS
AGREEMENT (this "First Amendment"), which amends the SECOND AMENDED AND RESTATED
AGREEMENT AMONG SERIES E, SERIES F and SERIES G PREFERRED STOCKHOLDERS AND
SENIOR REGISTRATION RIGHTS AGREEMENT (the "Second Amended and Restated
Agreement") dated as of September 7, 1999 by and among AirNet Communications
Corporation, a Delaware corporation (the "Company"), Harris Corporation, a
Delaware corporation ("Harris"), the Series E Preferred Stockholders listed on
Exhibit A thereto ("Series E Investors"), the Series F Preferred Stockholders
listed on Exhibit B thereto, the Series G Preferred Stockholders listed on
Exhibit C thereto, Tandem PCS Investments, L.P., a Delaware limited partnership
("Tandem"), Adams Capital Management, L.P. ("Adams"), SCP Private Equity
Partners, L.P. ("SCP"), HVFM-I, L.P. ("HVFM"), APA Excelsior III, L.P. ("APA")
and such other purchasers identified therein is made as of September 20, 1999 by
and among the Company, Tandem, Adams, SCP, HVFM, APA and the other shareholders
identified on the signature pages hereto (Tandem, Adams, SCP, HVFM, APA and such
other shareholders are collectively, "Shareholders").

                                   WITNESSETH:

WHEREAS, the Company is contemplating an initial public offering of shares of
its authorized but unissued common stock, in accordance with the terms of a
registration statement to be filed with the Securities and Exchange Commission;
and

WHEREAS, the Company and the Shareholders desire to amend the Second Amended and
Restated Agreement in accordance with Section 4.9 thereof to clarify certain
provisions relating to piggyback registration rights.

NOW, THEREFORE, intending to be legally bound, the parties hereto agree that the
Second Amended and Restated Agreement is hereby amended as follows:

       1.    Section 2.2(a) of the Second Amended and Restated Agreement is
hereby amended and restated in its entirety as follows:

             "2.2   Piggyback Registration

                    (a)    Notice of Piggyback Registration and Inclusion of
Registrable

<PAGE>   2

Securities. Subject to the terms of this Agreement, in the event the Company
decides to Register any of its securities (either for its own account or the
account of a security holder other than pursuant to a demand Registration) on a
form that would be suitable for a Registration involving Registrable Securities
and such Registration does not relate to an initial public offering of the
Company's securities (which Registration pursuant to an initial public offering
shall not trigger piggyback rights hereunder), the Company will (i) promptly
give each Holder written notice thereof (which shall include a list of the
jurisdictions in which the Company intends to attempt to qualify such securities
under the applicable Blue Sky or other state securities laws) and (ii) include
in such Registration (and any related qualification under Blue Sky laws or other
compliance), and in any underwriting involved therein, all the Registrable
Securities specified in a written request delivered to the Company by any Holder
within fifteen (15) days after delivery of such written notice from the
Company."

       2.    Section 2.2(b)(iii) of the Second Amended and Restated Agreement is
hereby amended and restated in its entirety as follows:

                           "(iii)    Allocation of Shares in Piggyback
Registration. In the event that the Underwriter's Representative limits the
number of shares to be included in a Registration pursuant to Section
2.2(b)(ii), or shall otherwise require a limitation of the number of shares to
be included in the Registration, then the Company will include in such
Registration first securities proposed by the Company to be sold for its own
account, the registration of which will not be limited or otherwise restricted
as a result of the Underwriter's Representative's limit. If after including in
the Registration the securities proposed by the Company to be sold for its own
account, the number of shares proposed for Registration by Holders pursuant to
Section 2.2 must be limited in order to avoid exceeding the Underwriter's
Representative's limit, the securities proposed by any member of Key Management
to be sold for his/her own account shall be reduced (including the elimination
of all such securities from the Registration, if necessary) such that such
Registration does not exceed the Underwriter's Representative's limit. If after
reducing the number of securities proposed by any member of Key Management to be
sold for his/her own account to zero, it is necessary to limit the shares
proposed for Registration by other Holders, the limitation on the number of
shares proposed for Registration by such other Holders shall be applied on a pro
rata basis based upon the number of shares of such securities proposed to be
sold and so requested to be included by such other Holders so that such
Registration does not exceed the Underwriter's Representative's limit."

       3     Section 2.1(e)(iii) of the Second Amended and Restated Agreement is
hereby amended and restated in its entirety as follows:

             "(iii)    Marketing Limitation in Demand Registration.  In the
event the Underwriter's Representative advises the Initiating Holders or
Significant Holder, as the case may be, in writing that market factors
(including, without limitation, the aggregate number of shares of Common Stock
requested to be Registered, the general condition of the market, and the status
of the persons proposing to sell securities pursuant to the Registration)
require a limitation of the number of shares to be underwritten, the securities
proposed by any member of Key Management to be sold for his/her own account
shall be reduced (including the elimination of all

<PAGE>   3

such securities from the Registration, if necessary) such that such Registration
does not exceed the Underwriter's Representative's limit. If after reducing the
number of securities proposed by any member of Key Management to be sold for
his/her own account to zero, it is necessary to further limit the number of
shares to be underwritten, the limitation on the remaining securities proposed
for Registration (including securities proposed by the Company to be sold for
its own account or for the accounts of others at the Company's request) shall be
applied on a pro rata basis based upon the number of shares of such securities
proposed to be sold and so requested to be included in the Registration so that
such Registration does not exceed the Underwriter's Representative's limit. No
Registrable Securities or other securities excluded from the underwriting by
reason of this Section 2.1(e)(iii) shall be included in such Registration
Statement."

       4     This First Amendment may be executed in any number of counterparts
with the same effect as if all signatory parties had signed the same document.
All counterparts shall be construed together and shall constitute one and the
same instrument.

       5     Except as amended by this First Amendment, the Second Amended and
Restated Agreement remains in full force and effect.

                                                   October 29, 1999



AirNet Communications Corporation
100 Rialto Place, Suite 300
Melbourne, FL 32901

Ladies and Gentlemen:

     We have acted as counsel for AirNet Communications Corporation, a Delaware
corporation (the "Company"), in connection with the initial public offering by
the Company of up to 5,500,000 shares and up to an additional 825,000 shares to
cover over-allotments (the "Shares") of its Common Stock, $.001 par
value per share.

     In connection with this opinion, we are familiar with the corporate
fproceedings of the Company and we have examined the Certificate of
Incorporation of the Company and the Registration Statement on Form S-1 (No.
333-87693), filed initially with the Securities and Exchange Commission under
the Securities Act of 1933 on September 24, 1999, as thereafter amended (the
"Registration Statement"), relating to the above-mentioned proposed public
offering. In addition, we have examined such corporate records, certificates
and other documents, and reviewed such questions of law, as we have deemed
necessary or advisable in order to enable us to render the opinion contained
herein.

     In our examination of the foregoing documents, we have assumed the
genuineness of all signatures and the authenticity of all documents submitted to
us as originals, the conformity to unsigned documents of all documents submitted
to us as certified or photostatic copies and the authenticity of the originals
of such documents.

     We assume that appropriate action will be taken, prior to the offer and
sale of the Shares, to register and qualify the Shares for sale under all
appropriate State "Blue Sky" and securities laws. Based upon the foregoing, we
are of the opinion that, upon consummation of the proposed initial public
offering, the Shares, when issued and delivered in the manner and for the
consideration stated in the Prospectus constituting a part of the Registration
Statement, will be legally issued, fully paid and non-assessable.

     We consent to the filing of this opinion as an Exhibit to the Registration
Statement and to the use of our name in the Registration Statement and the
Prospectus constituting a part thereof.

                                Very truly yours,

                                /s/ EDWARDS & ANGELL, LLP

<PAGE>   1
                                                                    EXHIBIT 10.3

           Employee Noncompete and Post-Termination Benefits Agreement

In consideration of the continued employment of R. Lee Hamilton, Jr. (the
"Employee") by AirNet Communications Corporation (the "Corporation"), for the
compensation received and for the severance benefit set forth below, Employee
agrees as follows:

1.     Employee recognizes that the Corporation has expended and continues to
expend significant resources in establishing its various businesses, in
developing its products and services, and in fostering goodwill and customer
relations. To do this, the Corporation and its employees develop and obtain
information, data and knowledge which is not generally known to others, and
which is entitled to protection from disclosure or misappropriation.

2.     In order to prevent the improper disclosure or use of trade secrets and
other confidential information and to protect the Corporation from unfair
competition, Employee agrees that during his employment and during the Severance
Period (as defined in Paragraph 10(b) below), Employee will not, either directly
or indirectly,

       (a) own any interest in (except for ownership of shares in a
       publicly-traded company not exceeding five percent of any class of
       outstanding securities), or be an employee, agent, director, advisor or
       consultant to or for any corporation (other than the Corporation or an
       affiliate of the Corporation), business enterprise or person engaged
       anywhere in the world in the development, manufacture, providing, sale,
       marketing, promotion or distribution of any base station product, product
       lines or services competitive with any manufactured, provided, sold,
       marketed, promoted or distributed by the Corporation, and Employee shall
       not assist in, manage or supervise any of the foregoing activities
       (hereinafter referred to as "Competitive Activities"); provided, however,
       this Paragraph 2(a) shall not be deemed to prevent Employee from working
       after termination of such Severance Period in any areas or division
       within the wireless industry.

       (b) undertake any action to induce or cause any customer or client of the
       Corporation who had been a customer or client during Employee's term of
       employment with the Corporation to discontinue any part of its business
       with the Corporation; or

       (c) cause, induce or in any way facilitate the employment by any other
       person or organization of any employee of the Corporation who had been an
       employee during Employee's term of employment with the Corporation.

Notwithstanding anything to the contrary contained elsewhere in this Agreement,
beginning with

L. Hamilton 10-8-99

<PAGE>   2

the first day of the tenth month of the Severance Period, Employee shall be
entitled to engage in Competitive Activities provided, however, that if Employee
elects to engage in Competitive Activities during the Severance Period pursuant
to this Paragraph 2, the Corporation shall not thereafter be obligated to pay or
provide, and the Employee shall not thereafter be entitled to receive and hereby
waives, the severance pay and health and life insurance benefits provided for
under Paragraphs 10(a), 10(b) and 10(c) of this Agreement (hereinafter referred
to as the "Contingent Severance Benefits"). In this regard, in the event
Employee elects to engage in Competitive Activities during the Severance Period
pursuant to this Paragraph 2, the Corporation shall be forever relieved of its
obligation to pay and provide the Contingent Severance Benefits, beginning with
the first day on which Employee engages in such Competitive Activities. In the
event Employee elects to engage in Competitive Activities pursuant to this
Paragraph 2, Employee shall deliver to the Corporation a written notice of his
intention to engage in Competitive Activities pursuant to this Paragraph 2 and
the date on which such Competitive Activities will commence. Nothing herein
shall be construed to restrict Employee's right to accept employment in any
business not competitive with that of the Corporation.

3.     Employee agrees and acknowledges that the rights and obligations set
forth under this Agreement are of a unique and special nature and that the
Corporation will suffer irrevocable harm and is without an adequate legal remedy
in the event Employee violates the agreements set forth herein. Employee
therefore agrees that the agreements made by Employee under this Agreement shall
be specifically enforceable in equity and that the Corporation may obtain an
injunction enjoining the violation of any provision in this Agreement, in
addition to all other rights and remedies at law or in equity that may be
available to the Corporation. The prevailing party shall be entitled to recover
all costs (including attorneys' fees) incurred by such prevailing party in
connection with any arbitration, suit or other proceeding with respect to this
Agreement.

4.     Any consent to or waiver of any breach or default in the performance of
any obligations hereunder or under any other agreement shall not be deemed or
construed to be a consent to or waiver of any other breach or default in the
performance of any of the same or any other obligations hereunder. Failure on
the part of the Corporation or Employee to complain of any act or failure to act
of the other party or to declare the other party in default, irrespective of the
duration of such failure, shall not constitute a waiver of rights hereunder and
no waiver hereunder shall be effective unless it is in writing and executed by
the party waiving the breach or default hereunder.

5.     This Agreement shall be governed by and construed in accordance with the
laws of the State of Florida. If a dispute arises out of or relates to this
Agreement and if said dispute cannot be resolved through direct discussions, the
parties agree to endeavor first to settle the dispute in an amicable manner by
mediation administered by the American Arbitration Association under its
National Rules for the Resolution of Employment Disputes. Thereafter, any
unresolved dispute arising out of or relating to this Agreement or the breach,
termination or validity thereof shall be settled by binding arbitration in
accordance with the National Rules for the Resolution of Employment Disputes of
the American Arbitration Association, before one neutral arbitrator, in
Melbourne, Florida. The arbitrator shall have the authority to award legal
relief for a material


                                     - 2 -
<PAGE>   3



breach of this Agreement and to grant injunctive relief pursuant to paragraph 3
of this Agreement. Any award entered by the arbitrator, including injunctive
relief, shall be final and binding and judgment may be entered thereon by any
party in any court of competent jurisdiction in the State of Florida.

6.     If any provision of this Agreement shall, in whole or in part, prove to
be invalid for any reason, such invalidity shall affect only the portion of such
provision which shall be invalid, and in all other respects this Agreement shall
stand as if such invalid provision, or other invalid portion thereof, had not
been a part of this Agreement. In view of the substantial harm which shall
result from Employee's breach of any of the agreements contained herein, the
Corporation and Employee agree that such agreements shall be enforced to the
fullest extent permitted by law. Accordingly, if, in any judicial proceeding, a
court shall determine that such agreements and restrictions are unenforceable
because they are too extensive in scope or survive for too long a period of
time, or for any other reason, then the Corporation and Employee intend that the
agreements or restrictions shall be deemed to cover such maximum scope and
maximum period of time and shall otherwise be deemed to be limited in such
manner as shall permit enforceability by such court.

7.     Nothing in this Agreement shall be construed so as to limit (i) any
obligation owing by Employee to the Corporation under that certain Proprietary
Information and Inventions Agreement dated July 30, 1996 between the Corporation
and Employee or (ii) any obligation owing by Employee to the Corporation or the
Corporation to the Employee as a matter of common law.

8.     Employee has not been promised any specific term of employment with the
Corporation, his employment is on an "at will" basis, and Employee agrees that
neither this Agreement nor any other agreement, whether in writing or verbally,
constitutes or promises a specific term of employment.

9.     Employee understands that if his employment with the Company is
terminated for any reason, Employee will continue to be bound by the provisions
of this Agreement regardless of the reasons or circumstances surrounding such
termination. However, if the Corporation terminates Employee's employment during
the term of this Agreement for (1) any reason other than for "cause" as defined
below or (2) Employee resigns his employment for a "Good Reason" as defined
below (either to be considered a "Termination Event"), Employee will be entitled
to the following benefits as additional consideration for the covenants
contained in this Agreement:

       (a) Severance pay in the form of regular installments of Employee's
       weekly base salary at the time of termination (less deductions required
       by law) on the same scheduled dates as if Employee were actively
       employed, for a period of one year following his termination, or until
       Employee engages in Competitive Activities pursuant to Paragraph 2 above,
       whichever occurs first.;

       (b) Continued coverage under the Corporation's health insurance policy in
       effect for


                                     - 3 -
<PAGE>   4

       the period (the "Severance Period") that Employee is receiving severance
       payments under paragraph 10(a) above;

       (c) Continued coverage under the Corporation's group life insurance
       policy, if any, at the benefit levels that Employee enjoyed immediately
       prior to his termination, for the Severance Period;

       (d) Employee is currently the holder of stock options to purchase shares
       of Common Stock of the Corporation (the "Options"). The parties agree
       that the Options shall vest and be exercisable in accordance with the
       existing provisions of the plan or agreement pursuant to which they were
       granted, except that in the event of a Termination Event (i) the exercise
       provisions relating to those Options which vest and become exercisable on
       or prior to the date of the Termination Event (including those Options
       entitled to accelerated vesting under subparagraph (ii) below), shall be
       modified to provide that such Options may be exercised by Employee at any
       time prior to that date which is eighteen (18) months following the date
       of the Termination Event , (ii) the vesting provisions relating to those
       Options which would otherwise vest on or prior to the later of February
       24, 2001 or that date which is one year following the date of the
       Termination Event shall be modified to provide that such Options vest and
       become exercisable on the date of the Termination Event and (iii) the
       Corporation shall promptly take such actions on its part as are
       necessary, including the amendment of any such stock option agreements,
       to modify the exercise and vesting provisions of such Options in
       accordance with the terms of this Paragraph 10(d). The parties agree that
       those Options which are not fully vested and exercisable on or prior to
       the date of the Termination Event after giving effect to the provisions
       of this Paragraph 10(d) shall not vest and shall be forfeited by
       Employee.

       (e) Employee understands that the full applicable payroll deductions for
       withholding and any contributions to group insurance benefits will remain
       in effect during the Severance Period.

For the purpose of eligibility for these severance benefits, termination for
"cause" is defined as termination for Employee's intentional bad faith act or
omission, criminal act, or gross dereliction of duty, which is materially
harmful or damaging to the Corporation, or material breach of any of Employee's
obligations under the Proprietary Information and Inventions Agreement executed
by the Corporation and Employee or under this Agreement.

For purposes of eligibility for severance benefits, a "Termination Event" shall
include termination of Employee for any reason other than for "cause" as defined
above or if Employee resigns employment for "Good Reason." "Good Reason" shall
mean, without the Employee's written consent (a) Employee is assigned a new
position which entails a reduction in the nature of Employee's authority with
respect to the operation of the Company's business; (b) a reduction in the
Employee's annual base salary or an adverse change in benefits or perquisites
other than a

change that is generally applicable to all executive employees; (c) the
Company's requirement that the Employee's site of principal employment be more
than twenty-five miles from the offices at which the Employee is principally
employed on the date of this Agreement.

10.    The Corporation and Employee hereby acknowledge that in the event
Employee is entitled to a severance payment or payments under that certain
Amended and Restated Change of Control, Severance and Bonus Agreement dated
March 17, 1999 between the Corporation and Employee (the "Change of Control,
Severance and Bonus Agreement") or any other agreement between the Corporation
and Employee, the severance pay to which Employee is otherwise entitled under
Paragraph 10(a) of this Agreement shall be reduced by the amount of any
severance payment(s) received by Employee pursuant to the terms of the Change of
Control, Severance and Bonus Agreement and/or any other agreement. In this
regard, this Agreement shall be construed so as to preclude Employee from
receiving duplicative severance payments from the Corporation pursuant to the
terms of more than one agreement between the Corporation and Employee.

11.    This Agreement shall terminate eighteen (18) months from the date of
execution of this Agreement.

12.    This Agreement may be executed in several counterparts, each of which
shall be deemed to be an original, but all of which together shall constitute
one and the same instrument.

13.    Except for the rights of Employee under this Agreement, in the event of a
Termination Event, as a condition to the Corporation's obligation to pay any
payments or benefits which may be due under Section 10 of this Agreement, the
Employee shall first execute and deliver an agreement unconditionally and
irrevocably releasing and forever discharging the Corporation of and from, and
the Employee will agree not to sue and not to assert against the Corporation,
any causes of action, claims and demands whatsoever, known or unknown, at law,
in equity, or before any agency or commission of local, state and federal
governments, arising, alleged to have arisen or which might have been alleged to
have arisen, or which may arise (i) in connection with Employee's employment
with the Corporation , (ii) in connection with Employee's performance of the
duties of his employment with the Corporation , or (iii) under any law
including, but not limited to federal, state or municipal anti-discriminating
laws such as The Americans With Disabilities Act, Title VII of the Civil Rights
Act of 1964, as amended in 1972, 1991, and the Age Discrimination in Employment
Act of 1967, that Employee on its own behalf and on behalf of his heirs,
executors, administrators or assigns, ever had, now has or hereafter can, shall
or may have against the Corporation for or by reason or any cause whatsoever.

14.    This Agreement shall be binding on and inure to the benefit of the
Corporation and its successors and assigns and to any of its subsidiaries which
Employee may at any time be employed as if named as the Corporation. This
Agreement may be amended only by written instrument executed by the parties to
this Agreement.

15.    This Agreement supercedes and replaces the Incentive Agreement between R.
