BACKGROUND

     In recent years, there has been an increase in demand for high performance
voice, data, facsimile and video communications. This trend, coupled with
regulatory changes in the United States and abroad and technological advances,
has led to significant growth in the number of users for existing
telecommunications capacity and the emergence of new wireless services for both
mobile and fixed applications.

     In response to this increased demand, existing mobile wireless service
providers, such as cellular service providers, have begun upgrading their
networks to more effectively use their allocated frequency spectrum to
accommodate more users and provide enhanced additional features, such as paging
or facsimile service. One such method of increasing capacity involves dividing
existing coverage cells into several smaller radius cells, which allows the same
frequency of the 

                                       1.
<PAGE>
 
radio spectrum to be reused in adjacent cells. At the same time, other
telecommunications service providers are beginning to establish PCN/PCS networks
to provide a broad range of mobile wireless communications similar to these
enhanced cellular services. These microcellular upgrades to existing systems and
new PCN/PCS networks require the establishment of additional, interconnected
base stations.

     Additionally, there has been a worldwide trend toward privatization of
public telephone operators ("PTOs") and deregulation of local loop services.
This trend has resulted in increased competition among companies seeking to
provide local access to the Public Switched Telephone Network ("PSTN"), which
has resulted in increased spending by existing PTOs and the emergence of new
companies providing fixed telecommunications services. As companies enter this
market, they must establish an infrastructure to deliver local fixed
telecommunications services and interconnect that infrastructure with the PSTN.
This local access and interconnect can often be implemented using wireless
technology at a cost and time advantage to wireline alternatives.

     As competition among service providers intensifies, it is becoming
increasingly important for them to respond quickly to changes in user patterns
and preferences. This frequently involves increasing the coverage of their
networks but also involves adding additional features, functionality, and
service offerings to their customers. As time to market has become ever more
critical, network service providers have increasingly looked to outside
suppliers, including equipment suppliers, for services such as network design
and installation. These service providers have also come to expect their
equipment suppliers to develop and offer additional products for new service
offerings, such as point-to-multipoint product offerings and access devices for
connecting their networks with the customers end site. Point-to-multipoint
offerings are being driven by the need for greater flexibility and more
efficient use of spectrum allocations. Equipment providers with expertise in
these areas are becoming critical for the implementation of network upgrades and
next generation network buildout.

     Millimeter wave radio systems are increasingly utilized for short-haul
wireless connections such as base station interconnect, local fixed
telecommunications access, and interconnect to the PSTN. The lower end of the
radio frequency spectrum, encompassing the traditional microwave frequency
bands, requires the use of more expensive equipment and has become increasingly
congested as compared to the millimeter wave frequency bands. Moreover, higher
frequencies allow a greater number of channels to be allocated in the same
percentage of spectrum compared to lower frequencies. The shorter transmission
distances of higher frequencies also allow these frequencies to be reused in
adjacent geographic areas whereas lower frequencies often propagate beyond the
desired locale into nearby areas. Therefore, regulatory authorities responsible
for the allocation of the radio wave spectrum are under increasing pressure to
assign millimeter wave frequency bands to those applications that can
effectively utilize this portion of the spectrum.

     Most conventional millimeter wave radio systems have been introduced by
suppliers of microwave technology based on architectures that were originally
designed and optimized for microwave frequency bands. These conventional systems
often are expensive to install and configure, lack certain advanced features and
do not readily support remote system management and maintenance. The Company
believes that there is a significant market opportunity for short-haul
communications solutions that are optimized for millimeter wave applications and
offer high levels of functionality, ease of installation and a low cost of
ownership.

THE P-COM SOLUTION

  Existing Products and Services

     P-Com offers equipment and services necessary to access telecommunications
and broadcast networks worldwide. The Company's Tel-Link(R) millimeter wave
radio systems and proprietary software offer telecommunications service
providers wireless connections for short-haul applications. The Company also
utilizes both frequency shift keying ("FSK") and spread spectrum modulation
techniques in its products. These systems are designed to be highly reliable,
cost-effective and simple to install and maintain, thus lowering the service
provider's overall cost of ownership. Additionally, the Company offers complete
turnkey relocation services for new licensees of radio spectrum who must first
remove current users of the frequencies before building out new networks, and
also offers network design, construction, and maintenance services. P-Com also
offers frame relay and integrated access products for network service providers
to facilitate managed connections of end users to their network. The Company
markets its systems and services to cellular and PCN/PCS service providers
implementing microcellular networks and to companies offering local loop
telecommunications services.

                 Diagram describing Local Access Applications.

     The Company believes its current solutions offer the following benefits:

     Commonality of Architecture. The Company's Tel-Link(R) systems employ a
design architecture that is optimized for operation at millimeter wave and
microwave frequencies. In contrast to most conventional radio systems, the
Company's systems across this frequency range are identical in architecture,
functionality and features, except for the final stage of the system which
determines the transmit and receive frequencies. This degree of commonality
assists P-Com in providing a range of products to customers that operate
systems in numerous millimeter wave and microwave bands. Currently, the
Company is shipping 7GHz, 13 GHz, 14 GHz, 15 GHz, 18 GHz, 23 GHz, 26 GHz, 38
GHz and 50 GHz systems. The common architecture employed in the Company's
systems is designed to offer P-Com's customers lower overall cost of ownership
and ease of system implementation through such benefits as reduced spare part
inventories, common features and software across the family of systems,
reduced training and easy integration into a network management system. The
Tel-Link(R) systems employ a high level of circuit integration, with the
concomitant advantages of fewer components and connections, less heat
dissipation and reduced human involvement in production and testing.

     Ease of Installation. The Company's systems were designed to lower
installation costs by minimizing the time and effort involved in system
implementation. The two primary assemblies of the systems, the outdoor unit
("ODU"), which is typically located on a tower or a rooftop, and the indoor unit
("IDU"), are connected with a single coaxial cable. Most conventional systems
require multiple cable connections between the IDU and the ODU, are manually
tuned and require numerous mechanical adjustments. The Company's systems are
smaller and lighter than conventional systems, and are software-configurable,
requiring minimal manual tuning and mechanical adjustments during installation.

                                       3.
<PAGE>
 
     High Level of Software Functionality. The Tel-Link(R) architecture is
designed to provide the Company's customers with a high level of functionality
to facilitate operation of the systems. The configuration of the Company's
systems, including setting the system's power and frequency and upgrading its
capacity, can be performed via the keypad located on the IDU. The Company also
offers proprietary Windows and SNMP-based software tools that permit a user to
perform system configuration from a personal computer attached directly to the
IDU or from any remote location accessed through a network management system.
The capacity of the Company's systems can be upgraded through software,
providing a greater degree of flexibility for customers. In contrast,
conventional millimeter wave systems typically require mechanical adjustments
and manual tuning on both the IDU and ODU, and their capacities cannot be
upgraded using software.

     Cost-effective Maintenance. The ease of maintenance of the Tel-Link(R)
systems is primarily due to the software embedded in the system and its software
tools. The Company includes a significant amount of the system's circuitry in
the IDU where system reliability is increased due to less demanding temperature
extremes and maintenance is easier to perform. Most conventional systems contain
more circuitry in the ODU, which exposes the circuitry to a wider temperature
range. This may require that more maintenance take place in the ODU, which is
typically more difficult to access. Use of the Company's proprietary maintenance
software tools can be on-site at the IDU or from any remote location through a
network management system. These tools allow the user to read the status of
numerous radio parameters and to change settings and configurations if desired.
Maintenance tools offered with the Tel-Link(R) systems include in-service
performance monitoring and analysis, system alarm reporting and IDU and ODU
temperature readings.

     Comprehensive Services. The Company provides turnkey microwave relocation,
engineering, installation and commissioning, and program management services to
the telecommunications industry. Such service packages assist in meeting the
critical cost and timeline objectives demanded by the wireless industry. The
Company's service division is designed to be involved in the aspects of system
build-out, including such tasks as: needs and objectives assessment, system and
program planning, network engineering, operations, maintenance, frequency
coordination and resolution of regulatory issues, management reporting,
training, installation, commissioning and acceptance, and preparation of
documentation. The Company provides these services either directly or through
approved subcontractors.

  Products Under Development

     Point-to-Multipoint Products. The re-allocation of spectrum in many bands
ranging from 2.4 GHz to 40 GHz is enabling the development of new services such
as local multipoint distribution service (LMDS) and local multipoint
communications service (LMCS). These services address the desire of service
providers for more efficient use of spectrum within a particular service area.
Certain bandwidth demand thresholds must be met before a customer can
economically justify the cost of a dedicated point-to-point system. Point-to-
multipoint provides the flexibility for a service provider to offer customers
wireless bandwidth on demand thereby creating the concept of a wireless central
office. The Company is currently developing a point-to-multipoint system to
provide service to end users from a hub station in a cell typically extending
from 1 to 10 kilometers. Cell size is based on frequency, traffic requirements,
and desired availability. The hub consists of one to 24 sector subsystems that
include sectorized antennae and their associated communications equipment. Each
sector subsystem covers from 15 to 90 degrees of azimuth with additional sector
subsystems providing up to 360 degrees of coverage. The diagram below
illustrates the potential use of the Company's point-to-multipoint system to
connect end-users to a hub station:

radio systems operating in millimeter wave and spread spectrum microwave
frequency bands, as well as related service offerings such as microwave
relocation. The following are the key elements of its strategy to achieve this
objective:

     Focus on Millimeter Wave and Spread Spectrum Microwave Market. The Company
is designing its products specifically for the millimeter wave and spread
spectrum microwave frequency band. The Company's core architecture is designed
to optimize its systems for operation at millimeter wave and microwave
frequencies. The Company currently ships 2.4 GHz, 5.7 GHz, 7 GHz, 13 GHz, 14
GHz, 15 GHz, 18 GHz, 23 GHz, 26 GHz, 38 GHz and 50 GHz systems. The Company is
selling its systems primarily to cellular and PCN/PCS service providers
implementing microcellular networks (Code Division Multiple Access (CDMA), Time
Division Multiple Access (TDMA) and Extended Time Division Multiple Access (E-
TDMA)), PTO companies offering local loop services and service companies
providing alternative access. The Company is developing systems which operate at
additional millimeter wave and spread spectrum microwave frequencies.

     Provide Ancillary Services in RF Engineering and System Construction. The
Company recently entered the market for relocation services for new licensees of
radio frequency spectrum. These services, which move existing users of a
specific radio frequency in order to clear the path for a new user, allow the
new licensees to outsource the relocation effort to P-Com. The Company believes
this service business will provide it with many strategic advantages, including
allowing it to develop strong relationships with decision makers early in the
network buildout process

                                       5.

This business unit has expanded to also provide engineering, program management,
installation and maintenance of communications systems.

     Continue to Expand Worldwide Presence. The Company is focused on expanding
its presence internationally and further establishing its market position in the
United States. To date, the market opportunities for the Company's systems have
been greater abroad, as the markets for PCN/PCS and microcellular networks and
local loop access have developed at a faster rate than in the United States. The
Company intends to continue its international focus by meeting international
telecommunications standards where appropriate and using strategic alliances to
penetrate international markets. The Company has met the standards established
by the European Telecommunications Standards Institute ("ETSI") and achieved
regulatory approval for certain of its systems in many countries including,
Australia, the Czech Republic, France, Germany, Greece, Hungary, Italy, Mexico,
Spain, the United Kingdom, and the United States. The process for additional
regulatory approvals for certain systems is underway in numerous other
countries, including Belgium, China and Switzerland. The Company's management
team consists of a group of highly-experienced telecommunications executives
from Italy, the United Kingdom and the United States. The Company maintains
offices throughout the world, has acquired numerous companies throughout the
world, and will continue to open offices in new geographic areas as needed in
order to support sales and customer support efforts.

     Build and Sustain Manufacturing Cost Advantage. The Company has designed
its system architecture to reduce the number of components incorporated in each
system and to permit the use of common components across the range of the
Company's products. The Company believes this will assist in the reduction of
its manufacturing costs by permitting volume component purchases and enabling a
standardized manufacturing process. The Company utilizes contract manufacturers
to service its volume requirements, reserving its internal manufacturing
capabilities to produce initial quantities of new products prior to commencement
of volume shipments and to respond to special customer requirements regarding
specifications or delivery.

     Leverage and Maintain Software Leadership. The Company seeks to
differentiate its systems through the proprietary software embedded in the IDU
and ODU and its Windows and SNMP-based software tools. This software is designed
to allow the Company to deliver to customers a high level of functionality in a
system that can be easily configured by the user to meet particular needs. In
addition, the embedded software enables the capacity of the Company's systems to
be easily upgraded. Software tools are also offered to facilitate network
management of the system. The Company intends to continue its focus on software
development in order to support increasing levels of functionality and ease of
configuration and use of the Company's systems.

     Position P-Com for Emerging Applications and Markets. The Company intends
to market its systems for applications other than microcellular, PCN/PCS and
local loop services and to explore emerging geographic markets. Many growing
businesses and local government organizations are choosing to install, maintain
and manage their own telecommunications infrastructures and only interface with
a PTO where a connection to the public network is required. As the voice, data
and video traffic within an organization increases, this approach becomes more
cost-effective than leasing these intracompany services from a PTO. The Company
believes that additional markets may develop abroad, as the implementation of
the communications infrastructure upgrades in emerging countries increasingly
bypasses traditional wired networks and moves directly to a cost-effective
wireless network.

     Acquire Companies with Complementary Products and Services. The Company
believes that acquisitions of companies with complementary products and services
will allow the Company to expand the products and services that it offers to
both its own customer base and to the customer bases of the acquired companies.
The Company has acquired companies that offer spread spectrum radios, point-to-
multipoint distribution systems currently under development, microwave
relocation and system construction, wire-line access systems including advanced
frame relay network management products and integrated services access
platforms, engineering, program management and installation of wireless
communications, cable and fiber optic systems. The Company recently acquired
RT Masts Limited ("RT Masts"), a company based in England and Telematics, Inc.
("Telematics"), a company based in Virginia that supply, install and maintain
telecommunications systems and services, including antennae covering high
frequency, medium frequency and microwave systems, and also manage the
construction of radio system sites, as well as the construction of towers and
the installation of radios and antennae at system sites. In addition, on March
28, 1998, the Company acquired substantially all of the assets of the Wireless
Communications Group of Cylink Corporation, a Sunnyvale, California-based
company. The Wireless Communications Group designs, manufactures and markets
spread spectrum radio products for voice and data applications in both
domestic and international markets.

     Ongoing Development of Point-to-Multipoint Systems. The Company is
continuing to pursue development of point-to-multipoint radio systems for use in
both the telecommunications and broadcast industries. Incorporated into
networks, these systems are being designed to deliver broadband digital services
offering telephony, high-speed two-way data, video conferencing, Internet
access, and broadband video services. The systems are being designed to allow
alternative access to local circuit, packet and cell switching facilities within
metropolitan areas. The Company believes that the point-to-

                                       6.
<PAGE>
 
multipoint solution will provide high-bandwidth alternatives to traditional
network access methods. It is intended that this capability, along with the
Company's cell modeling capability, will allow the wireless carriers to increase
traffic capacity and revenues.

TECHNOLOGY

     The Company believes its approach to millimeter wave radio systems and
spread spectrum microwave is significantly different from most conventional
approaches. Through the use of its proprietary digital signal processing,
frequency converter and antenna interface technology, and its proprietary
software and custom application-specific integrated circuits, the Company offers
a highly-integrated, feature-rich system. This integration is designed to result
in reliability and cost advantages. The microprocessors and embedded software in
both the IDU and ODU enclosures enable flexible customization to the user's
specific telecommunications network requirements.

  Millimeter Wave and Microwave Technology

     Wireless transmission of voice, data and video traffic has become a
desirable alternative to wired solutions due to its advantages in the ease and
cost of implementation and maintenance. Since high frequency transmissions are
best suited for shorter distances, microwave radio frequencies are typically
used for communications links of 15 to 50 miles and millimeter wave radio
frequencies for transmissions of up to 15 miles. In addition, the cost of
millimeter wave radio systems is generally less than that of microwave radio
systems.

     Most conventional millimeter wave radio systems use technology that is very
similar to microwave radio technology, except that a millimeter wave frequency
source is used at the final stage instead of a lower frequency microwave source.
As depicted below, when transmitting, the IDU, which is the radio system's
interface to the end-user's equipment, sends an unmodulated digital transmit
signal to the ODU. In the ODU, this signal directly modulates a transmit Gunn
oscillator which has its final frequency controlled by a synthesizer. The
signal, now at the desired millimeter wave frequency, is then routed to the
antenna for transmission to the millimeter wave radio system at the receiving
end. At the receiving end, the incoming signal is mixed in a receive converter
with a receive millimeter wave frequency source, typically a Gunn oscillator
which has its frequency controlled by a synthesizer. The signal is then routed
through an intermediate frequency (IF) converter, demodulated, and the resultant
signal is then sent to the IDU where it is directed to the end-user's equipment.


         Diagram Describing Convention Technology and P-Com Technology

     P-Com believes that its millimeter wave technology is significantly
different from that contained in most conventional systems. When transmitting,
the Company's IDU sends an already-modulated, IF transmit signal to the ODU
where it is received by the IF processor, routed to the transmit converter and
mixed with a synthesized frequency source. This signal is then amplified and
passed through to the Company's proprietary frequency converter to establish the
appropriate millimeter wave frequency. The signal is then routed to the antenna
for transmission to the millimeter wave radio system at 

                                       7.
<PAGE>
 
the receiving end. At the receiving end, the incoming signal is routed to the
frequency converter and mixed in the downconverter with the same frequency
source that was used when transmitting. The signal is passed through the same IF
processor to the IDU where it is demodulated and sent to the end-user's
equipment.

     The spread spectrum products use quadrature phase shift keying ("QPSK") or
quadrature amplitude modulation ("QAM") in the IDU. This signal is upconverted
into a microwave or millimeter wave frequency in the ODU. This signal is then
routed to the antenna to be broadcast. The receiving antenna captures the signal
power and routes it to the ODU. The ODU down converts the signal to be
demodulated in the IDU.

     P-Com's architecture is designed to achieve reliability, cost, installation
and maintenance benefits over conventional approaches. The Company employs a
common architecture in the ODU for all stages of the system other than the
frequency converter used to establish the millimeter wave frequency at which the
system operates. In contrast, conventional millimeter wave systems often use
different designs for several components of the ODU for each different frequency
band. Third, the final transmit and receive frequencies are electronically
tunable either from the IDU or from a remote location using a network management
system. In contrast, many conventional approaches employ a Gunn oscillator to
generate the transmit millimeter wave frequency source and a second Gunn
oscillator to receive the millimeter wave transmission from the remote end.
These devices must be manually tuned and adjusted to achieve proper operation.
The Company believes that the Gunn oscillator technology that is typically used
in conventional approaches is inherently less reliable than P-Com's proprietary
frequency converter technology. Finally, in P-Com's systems, the IDU and ODU are
connected with a single coaxial cable, in contrast to many conventional systems
that require multiple cable connections.

  P-Com System Architecture

     The Company's millimeter wave and spread spectrum microwave radios comprise
three primary assemblies: the IDU, the ODU and the antenna. The IDU houses the
digital signal processing and the modem functions, and interfaces to the ODU via
a single coaxial cable. The ODU, a radio frequency (RF) enclosure, establishes
the specific transmit and receive frequencies and houses the proprietary P-Com
frequency converter. The antenna interfaces directly to the ODU via a
proprietary P-Com waveguide transition technology. The following diagram
illustrates a typical P-Com Tel-Link(R) radio system:
                                      
              Diagram Describing P-Com Tel-Link(R) Radio System.
                                        
     Indoor Unit (IDU) and Software. The IDU is the interface to the user's
network. It is an indoor mounted assembly that contains baseband electronics,
including the functions of line interface, digital signal processing,
modulation/demodulation and intermediate frequency generation. The IDU also
includes the alarm and diagnostic, service channel and 

                                       8.
<PAGE>
 
telecommunications network management interfaces. Finally, the IDU contains the
capability to set the system capacity, frequency synthesizer and power output of
the radio; no access to the ODU is required.

     The configuration of the Company's systems, including the setting of the
system's power, frequency and capacity, is performed via the keypad located on
the IDU. The Company also offers proprietary Windows and SNMP-based software
tools that permit a user to perform system configuration from a personal
computer attached directly to the IDU or from any remote location accessed
through a network management system. In contrast, conventional millimeter wave
systems typically require mechanical adjustments and manual tuning, which
involves sending maintenance personnel to the radio location. The software
embedded in the Company's systems also allows the easy upgrade of system
capacity; minimal hardware changes are required.

     Outdoor Unit (ODU). The ODU consists of a lightweight, compact, integrated
RF electronics enclosure which attaches to an antenna. The RF enclosure contains
the electronics that convert and amplify the modulated signal received from the
IDU. Typically, the ODU is installed outdoors on a tower or rooftop. The RF
enclosure is connected to the antenna with the Company's proprietary waveguide
transition that requires no alignment, tools or special techniques. It is
secured to the antenna with quick release clips that typically allow an
installer to replace the complete unit in less than five minutes. In addition,
since the antenna mount is independent of the RF enclosure, replacement of the
RF enclosure requires no realignment of the antenna.

     IDU-ODU Interconnection. The single coaxial cable connecting the Company's
IDU and ODU carries transmit and receive signals as well as DC power. This cable
can reach up to 1,000 feet without requiring additional amplification or a
setting for a specific length. No specific matching is required between the ODU
and IDU: any IDU within a particular capacity range will operate to full
specification with any ODU within that capacity range, irrespective of the
frequency band in which the ODU operates. Many conventional systems require
multiple cable connections, distance-specific settings and specific matching
between the IDU and the ODU.

testing point-to-multipoint systems to provide bandwidth management, increased
spectral efficiency, high availability, comprehensive network management,
increased user and network interfaces, and lower cost. The system is being
developed to be highly scalable, and to accommodate hub and remote site growth.
The Company intends to offer cost effective, highly efficient modulation schemes
such as 32 and 64 QAM at millimeter wave frequencies. There can be no assurance
that the Company will be able to successfully develop the point-to-multipoint
systems or that such products will achieve market acceptance. To date, no point-
to-multipoint systems have been shipped for revenue.

   Services

     P-Com, through its P-Com Network Services subsidiary ("Network Services"),
provides turnkey relocation of microwave links from spectrum reallocated by the
FCC for emerging technologies and applications. The providers of these emerging
technologies and applications, which include PCS licensees, must first relocate
the existing user or users to a comparable location on the frequency spectrum.
This relocation process requires substantial attention from radio engineering
personnel, and many service providers lack sufficient personnel resources to
both relocate existing users and build out a new network. Many providers seek to
outsource this relocation responsibility to a third-party, such as Network
Services. Network Services, which (through its predecessor) signed its first PCS
microwave relocation contract in January 1995, to date has performed microwave
relocation services on more than 1,000 paths.

     Network Services provides three principal microwave relocation services:
market and system analysis which involves the collection of data on the various
existing paths in a particular area, as well as the potential cost of comparable
paths for relocation; negotiation services which involves negotiations with
existing users of spectrum on behalf of the PCS licensee in order to agree on
the parameters of a new path; and program management which involves managing the
complete physical construction of a relocation path, including the procurement
of equipment and building permits, and installation and testing of the new
system; as well as turnkey relocation encompassing all of the above. Network
Services has expanded its service offerings through the acquisitions of RT Masts
and Telematics, which engage in the management of construction of radio system
sites, as well as construction of towers and the installment of radios and
antennae at system sites.

     Network Services' principal service is turnkey microwave relocation
services in which Network Services conducts all system analysis, negotiation,
and implementation and delivers to its client fully cleared spectrum.

     Network Services' customers include Sprint Spectrum, AT&T Wireless, PrimeCo
Personal Communications, BellSouth, Omnipoint, and SCPSA.

     Additionally, P-Com is expanding its service offerings to include such
services as network and path design, installation, and maintenance of the
service provider's network.

SALES AND MARKETING

     The Company's sales and marketing efforts are headquartered in the
Company's executive offices in Campbell, California. The Company has established
and staffed a sales and customer support facility in the United Kingdom that
serves as a base for the European market. Internationally, the Company uses a
variety of sales channels, including system providers, OEMs, dealers and local
agents, as well as selling directly to its customers. The Company has sales
offices or personnel located in China, England, France, Germany, Poland, Turkey,
Italy and Mexico, and has worldwide OEM agreements with Lucent Technologies,
Fujitsu and Italtel. In addition, the Company has established agent
relationships in numerous other countries in the Asia/Pacific region and in
South America and Europe. In the United States, the Company utilizes both direct
sales and OEM channels.

     The Company currently engages in a lengthy sales process that commences
with the solicitation of bids by prospective customers. If the Company is
selected to proceed further, the Company may provide systems for incorporation
into system trials or may proceed directly to contract negotiations. If system
trials are required and successfully completed, the Company then negotiates a
contract with the customer to set technical and commercial terms of sale. These
terms of sale govern the purchase orders issued by the customer as the network
is deployed. The Company anticipates that it will increasingly rely upon OEMs
and system providers during the sales process, and will therefore have less
direct contact during this process with end-users.

     The Company believes that due to the complexity of its radio systems, a
high level of technical sophistication is required on the part of the Company's
sales and marketing personnel. In addition, the Company believes that customer
service is fundamental to its success and potential for follow-on business. New
customers are provided engineering assistance for installation of the first
units as well as varying degrees of field training depending upon the customer's
technical aptitude. All customers are provided telephone support via a 24-hour
customer service help desk. The Company's customer service efforts are
supplemented by its system providers.

     The Company believes that it must continue to expand its sales and
marketing organization worldwide. Any significant sales growth will be dependent
in part upon the Company's expansion of its marketing, sales and customer
support capabilities, which will require significant expenditures to build the
necessary infrastructure.

CUSTOMERS

     The Company's principal customers currently include network operators,
which incorporate the Company's systems into networks to deliver communications
services directly to consumers, and system providers, which incorporate P-Com
systems into networks to be sold to network operators, that in turn provide
communications services directly to consumers. Certain customers may act as both
network operators and system providers depending on the circumstances.

   Network Operators

     These users include regulated and non-regulated providers of wireless
voice, data and video services to corporate and individual customers. Current
and potential applications include cellular and PCN/PCS networks (CDMA, TDMA and
E-TDMA), PTO/local loop service, network interconnections and access to long
distance networks. For cellular and PCN/PCS applications, users of P-Com's
systems in a single cellular service area may include multiple PCN/PCS
providers, wireline cellular service operators, non-wireline cellular service
operators and alternate service providers.

   System Providers

     These customers provide engineering and installation services for their
customers, which consist of cellular service providers, private corporations,
utilities and local government entities. Current and potential applications
include supervisory control systems for water, electric and gas companies, local
area networks for private corporations and educational institutions, and
voice/data/video networks for government users (police, fire, safety). These in-
country system providers accomplish the network design and provide the field
effort necessary to install, commission and maintain the Company's millimeter
wave and spread spectrum microwave systems. System providers are also
extensively used by PTOs and cellular and PCN companies in Eastern Europe,
Russia, China and other developing countries.

</TABLE>

     For the year ended December 31, 1997, approximately seventy-five customers
accounted for substantially all of the Company's sales, and two customers, each
of which individually accounted for over 10% of the Company's 1997 sales,
accounted for over 27% of the Company's sales. In 1996, the Company had five
customers which individually accounted for over 10% of the Company's sales.
Sales to Orange Personal Communications Ltd. and WinStar accounted for
approximately 16% and 11% of the Company's sales, respectively, in 1997. Sales
to Orange Personal Communications Ltd., WinStar, Bosch Telecom GmbH, Ericsson
Limited and ART accounted for approximately 18%, 12%, 11%, 11% and 11% of the
Company's sales, respectively, in 1996. As of December 31, 1997, seven customers
accounted for over 64% of the Company's backlog scheduled for shipment in the
twelve months subsequent to December 31, 1997. The Company anticipates that, at
least for the near term, it will continue to sell its radio systems to an
expanding but still relatively small, group of customers. Many of the Company's
customers are implementing new networks and may require additional capital to
implement fully their planned networks, e.g. Fareastone, Mercury Personal
Communications, Orange Personal Communications, Advanced Radio Telecom
Corporation and WinStar Wireless, Inc. The Company's ability to achieve or
increase its sales in the future will depend in significant part upon its
ability to obtain and fulfill orders from existing and new customers and
maintain relationships with and provide support to existing and new customers.
Equally important is its ability to manufacture systems on a timely and cost-
effective basis and to meet stringent customer performance and shipment delivery
dates. As a result, any cancellation, reduction or delay in orders by or
shipments to any customer, as a result of manufacturing difficulties or
otherwise, or the inability of any customer to finance its purchases of the
Company's radio systems may have a material adverse effect upon the Company's
business, financial condition and results of operations. There can be no
assurance that the Company's sales will increase in the future or that the
Company will be able to retain and support existing customers or to attract new
customers.

     The Company's backlog was approximately $65.2 million as of December 31,
1997, as compared to approximately $58.4 million as of December 31, 1996. The
increase is primarily due to the expansion of the Company's international
market. The Company includes in backlog only those firm customer commitments to
be shipped within the following twelve months. A significant portion of the
Company's backlog scheduled for shipment in the twelve months subsequent to
December 31, 1997 can be canceled since orders are often made substantially in
advance of shipment, and some of the Company's contracts provide that orders may
be canceled with limited or no penalties up to a specified period (generally 60
to 90 days) before shipment, and in some cases at any time. Therefore, backlog
is not necessarily indicative of future sales for any particular period. In
addition, the Company's customers have increasingly been requiring shipment of
products at the time of ordering rather than submitting purchase orders far in
advance of expected dates of product shipment.

                                      13.

MANUFACTURING

     The Company's manufacturing objective is to produce systems that conform to
P-Com's specifications at the lowest possible manufacturing cost. The Company
has designed its system architecture to reduce the number of components
incorporated in each system and to permit the use of common components across
the range of the Company's products. P-Com believes this will reduce its
manufacturing costs by permitting volume component purchases and enabling a
standardized manufacturing process. Where appropriate, the Company has developed
component designs internally to seek to obtain higher performance from its
systems at a lower cost. The Company is engaged in an effort to increase the
standardization of its manufacturing process in order to permit it to more fully
utilize contract manufacturers.

     As part of its program to reduce the cost of its radio systems and to
support an increase in the volume of orders, the Company first began to utilize
contract manufacturers to produce its systems, components and subassemblies in
the fourth quarter of 1994, and expects to rely increasingly on such
manufacturers in the future. Currently, these contract manufacturers are Remec,
Inc., Sanmina Corporation, SPC Electronics Corp., Senior Systems Technology,
Inc., GSS Array Technology and Celeritek, Inc.

     The Company also relies on outside vendors to manufacture certain
components and subassemblies used in the production of the Company's radio
systems. Certain components, subassemblies and services necessary for the
manufacture of the Company's systems are obtained from a sole supplier or a
limited group of suppliers. In particular, Eltel Engineering S.r.L. and
Associates, Milliwave, Scientific Atlanta, and Xilinx, Inc. each are sole source
or limited source suppliers for critical components used in the Company's radio
systems. The Company intends to reserve its internal manufacturing capacity for
new products and products manufactured in accordance with a customer's custom
specifications or expedited delivery schedule. Therefore, the Company's internal
manufacturing capability for standard products is very limited, and the Company
intends to rely on contract manufacturers for high volume manufacturing. There
can be no assurance that the Company's internal manufacturing capacity and that
of its contract manufacturers will be sufficient to fulfill the Company's
orders. Failure to manufacture, assemble and ship systems and meet customer
demands on a timely and cost effective basis could damage relationships with
customers and have a material adverse effect on the Company's business,
financial condition and operating results.

     The Company's reliance on contract manufacturers and on sole suppliers or a
limited group of suppliers and the Company's increasing reliance on
subcontractors involves several risks, including a potential inability to obtain
an adequate supply of finished radio systems and required components and
subassemblies, and reduced control over the price, timely delivery, reliability
and quality of finished radio systems, components and subassemblies. The Company
does not have long-term supply agreements with several of its manufacturers or
suppliers. In addition, the Company has from time to time experienced and may in
the future continue to experience delays in the delivery of and quality problems
with radio systems and certain components and subassemblies from vendors.
Manufacture of the Company's radio systems and certain of these components and
subassemblies is an extremely complex process, and there can be no assurance
that delays caused by contract manufacturers and suppliers will not occur in the
future. Certain of the Company's suppliers have relatively limited financial and
other resources. Although the Company intends to qualify alternative sources and
has the ability to manufacture its finished radio systems in limited quantities
and certain of such components internally, any inability to obtain timely
deliveries of components and subassemblies of acceptable quality or any other
circumstance that would require the Company to seek alternative sources of
supply, or to manufacture its finished radio systems or such components and
subassemblies internally could delay the Company's ability to ship its systems.
Any such delay could damage relationships with current or prospective customers
and could therefore have a material adverse effect on the Company's business,
financial condition and operating results.

RESEARCH AND DEVELOPMENT

     The Company has a continuing research and development program in order to
enhance its existing systems and related software tools and to introduce new
systems. The Company invested approximately $29.1 million, $20.2 million and
$12.3 million in 1997, 1996 and 1995, respectively, in research and development
efforts and expects to continue to invest significant resources in research and
development, including new product development and acquisitions.

     The Company's research and development efforts can be classified into three
distinct efforts: (1) increasing the functionality of its point-to-point radio
systems under development by adding additional frequencies and capacities to its
product portfolio, modifying its network management system software offering,
and developing other advancements to its point-to-point radio systems under
development; (2) developing new products based on its core technologies, such as
a point-to-multipoint product offering for applications such as cable or fiber
replacements; and (3) integrating new functionality to extend the reach of its
products into the customers' networks, such as access technology which allows
the 

                                      14.
<PAGE>
 
customer to manage telecommunications services at its site and integrate voice,
data, video and facsimile in one offering, such as the Company's NetPath
integrated access product. There can be no assurance that the Company will
continue to focus on these areas or that current efforts will result in new
product introductions or modifications to existing products.

     The wireless communications market is subject to rapid technological
change, frequent new product introductions and enhancements, product
obsolescence, changes in end-user requirements and evolving industry standards.
The Company's ability to be competitive in this market will depend in
significant part upon its ability to develop successfully, introduce and sell
new systems and enhancements and related software tools on a timely and cost-
effective basis that respond to changing customer requirements. The Company has
experienced and may continue to experience delays from time to time in
completing development and introduction of new systems, enhancements or related
software tools. There can be no assurance that errors will not be found in the
Company's systems after commencement of commercial shipments, which could result
in the loss of or delay in market acceptance. The inability of the Company to
introduce in a timely manner new systems, enhancements or related software tools
that contribute to sales could have a material adverse effect on the Company's
business, financial condition and results of operations.

COMPETITION

     The wireless communications market is intensely competitive. The Company's
wireless-based radio systems compete with other wireless telecommunications
products and alternative telecommunications transmission media, including copper
and fiber optic cable. The Company has experienced increasingly intense
competition worldwide from a number of leading telecommunications companies that
offer a variety of competitive products and services and broader
telecommunications product lines, including Adtran, Inc., Alcatel Network
Systems, California Microwave, Inc., Digital Microwave Corporation, Ericsson
Limited, Harris Corporation--Farinon Division, Nokia Telecommunications, Innova
Corp., Philips T.R.T., and Western Multiplex Corporation, many of which have
substantially greater installed bases, financial resources and production,
marketing, manufacturing, engineering and other capabilities than the Company.
The Company faces actual and potential competition not only from these
established companies, but also from start-up companies that are developing and
marketing new commercial products and services. The Company may also face
competition in the future from new market entrants offering competing
technologies. In addition, the Company's current and prospective customers and
partners, certain of which have access to the Company's technology or under some
circumstances are granted the right to use the technology for purposes of
manufacturing, have developed, are currently developing or could develop the
capability to develop or manufacture products competitive with those that have
been or may be developed or manufactured by the Company. The Company's results
of operations may depend in part upon the extent to which these customers elect
to purchase from outside sources rather than develop and manufacture their own
radio systems. There can be no assurance that such customers will rely on or
expand their reliance on the Company as an external source of supply for their
radio systems. The principal elements of competition in the Company's market and
the basis upon which customers may select the Company's systems include price,
performance, software functionality, ability to meet delivery requirements and
customer service and support. There can be no assurance that the Company will be
able to compete effectively with respect to such elements. Recently, certain of
the Company's competitors have announced the introduction of competitive
products, including related software tools, and the acquisition of other
competitors and competitive technologies. The Company expects its competitors to
continue to improve the performance and lower the price of their current
products and to introduce new products or new technologies that provide added
functionality and other features. New product introductions and enhancements by
the Company's competitors could cause a significant decline in sales or loss of
market acceptance of the Company's systems or intense price competition, or make
the Company's systems or technologies obsolete or noncompetitive. The Company
has experienced significant price competition and expects such price competition
to intensify, which may materially adversely affect its gross margins and its
business, financial condition and results of operations. The Company believes
that to be competitive, it will continue to be required to expend significant
resources on, among other items, new product development and enhancements. In
marketing its systems, the Company will face competition from vendors employing
other technologies that may extend the capabilities of their competitive
products beyond their current limits, increase their productivity or add other
features. There can be no assurance that the Company will be able to compete
successfully in the future.

GOVERNMENT REGULATION

     Radio communications are subject to extensive regulation by the United
States and foreign laws and international treaties. The Company's systems must
conform to a variety of domestic and international requirements established to,
among other things, avoid interference among users of radio frequencies and to
permit interconnection of equipment. Each country has a different regulatory
process. Historically, in many developed countries, the limited availability of
frequency spectrum has inhibited the growth of wireless telecommunications
networks. In order for the Company to operate in a 

                                      15.
<PAGE>
 
foreign jurisdiction, it must obtain regulatory approval for its systems and
comply with different regulations in each jurisdiction. Regulatory bodies
worldwide are continuing the process of adopting new standards for wireless
communication products. The delays inherent in this governmental approval
process may cause the cancellation, postponement or rescheduling of the
installation of communications systems by the Company and its customers, which
in turn may have a material adverse effect on the sale of systems by the Company
to such customers. The failure to comply with current or future regulations or
changes in the interpretation of existing regulations could result in suspension
or cessation of operations. Such regulations or such changes could require the
Company to modify its products and incur substantial costs to comply with such
time-consuming regulations and changes. In addition, the Company is also
affected to the extent that domestic and international authorities regulate the
allocation and auction of the radio frequency spectrum. Equipment to support new
services can be marketed only if permitted by suitable frequency allocations,
auctions and regulations, and the process of establishing new regulations is
complex and lengthy. To the extent PCS operators and others are delayed in
deploying these systems, the Company could experience delays in orders. Failure
by the regulatory authorities to allocate suitable frequency spectrum could have
a material adverse effect on the Company's business, financial condition and
results of operations. In addition, delays in the radio frequency spectrum
auction process in the United States could delay the Company's ability to
develop and market equipment to support new services. These delays could have a
material adverse effect on the Company's business, financial condition and
results of operations.

     The regulatory environment in which the Company operates is subject to
significant change. Regulatory changes, which are affected by political,
economic and technical factors, could significantly impact the Company's
operations by restricting development efforts by the Company's customers, making
current systems obsolete or increasing the opportunity for additional
competition. Any such regulatory changes, including changes in the allocation of
available spectrum, could have a material adverse effect on the Company's
business and results of operations. The Company might deem it necessary or
advisable to modify its systems to operate in compliance with such regulations.
Such modifications could be extremely expensive and time-consuming.

INTELLECTUAL PROPERTY

     The Company relies on a combination of patents, trademarks, trade secrets,
copyrights and a variety of other measures to protect its intellectual property
rights. The Company currently holds four U.S. patents, which number will
increase upon consummation of the acquisition of the wireless communications
group of Cylink Corporation. (See note 9 of Notes to Consolidated Financial
Statements.) The Company generally enters into confidentiality and nondisclosure
agreements with its service providers, customers and others, and attempts to
limit access to and distribution of its proprietary rights. The Company also
enters into software license agreements with its customers and others. However,
there can be no assurance that such measures will provide adequate protection
for the Company's trade secrets or other proprietary information, that disputes
with respect to the ownership of its intellectual property rights will not
arise, that the Company's trade secrets or proprietary technology will not
otherwise become known or be independently developed by competitors or that the
Company can otherwise meaningfully protect its intellectual property rights.
There can be no assurance that any patent owned by the Company will not be
invalidated, circumvented or challenged, that the rights granted thereunder will
provide competitive advantages to the Company or that any of the Company's
pending or future patent applications will be issued with the scope of the
claims sought by the Company, if at all. Furthermore, there can be no assurance
that others will not develop similar products or software, duplicate the
Company's products or software or design around the patents owned by the Company
or that third parties will not assert intellectual property infringement claims
against the Company. In addition, there can be no assurance that foreign
intellectual property laws will adequately protect the Company's intellectual
property rights abroad. The failure of the Company to protect its proprietary
rights could have a material adverse effect on its business, financial condition
and results of operations.

     Litigation may be necessary to enforce the Company's patents, copyrights
and other intellectual property rights, to protect the Company's trade secrets,
to determine the validity of and scope of the proprietary rights of others or to
defend against claims of infringement or invalidity. Such litigation could
result in substantial costs and diversion of resources and could have a material
adverse effect on the Company's business, financial condition and results of
operations. There can be no assurance that infringement, invalidity, right to
use or ownership claims by third parties or claims for indemnification resulting
from infringement claims will not be asserted in the future or that such
assertions will not materially adversely affect the Company's business,
financial condition and results of operations. If any claims or actions are
asserted against the Company, the Company may seek to obtain a license under a
third party's intellectual property rights. There can be no assurance, however,
that a license will be available under reasonable terms or at all. In addition,
should the Company decide to litigate such claims, such litigation could be
extremely expensive and time consuming and could materially adversely affect the
Company's business, financial condition and results of operations, regardless of
the outcome of the litigation.

                                      16.

EMPLOYEES

     As of December 31, 1997, the Company had a total of 754 employees,
including 357 in operations, 171 in research and development, 77 in sales and
marketing, 45 in quality assurance and 104 in administration. The Company
believes its future results of operations will depend in large part on its
ability to attract and retain highly skilled employees. None of the Company's
employees are represented by a labor union, and the Company has not experienced
any work stoppages. The Company considers its employee relations to be good.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.


     The Management's Discussion and Analysis of Financial Condition and Results
of Operations contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including those set forth under "--Certain Factors Affecting Operating Results"
contained in this Item 7 and elsewhere in this Annual Report on Form 10-K.


RESULTS OF OPERATIONS

OVERVIEW

     P-Com, Inc. (the "Company") supplies equipment and services for access to
worldwide telecommunications and broadcast networks. All financial information
presented in this Annual Report on Form 10-K has been restated to include the
operating results of Control Resources Corporation ("CRC"), which was acquired
in a pooling of interests transaction on May 29, 1997; and RT Masts Limited ("RT
Masts") and Telematics, Inc. ("Telematics"), which were acquired in pooling of
interests transactions on November 27, 1997. Currently, the Company ships 2.4
GHz and 5.7 GHz spread spectrum radio systems, as well as 7 GHz, 13 GHz, 14 GHz,
15 GHz, 18 GHz, 23 GHz, 26 GHz, 38 GHz and 50 GHz radio systems, all with
related software. The Company also provides related services for these products.

     The Company was founded in August 1991 to develop, manufacture, market and
sell millimeterwave radio systems for wireless networks. The Company was in the
development stage until October 1993. From October 1993 through December 31,
1997, the Company generated sales of approximately $454.9 million, of which
$220.7 million, or 49% of such amount, was generated in the twelve months ended
December 31, 1997. From inception to the end of 1997, the Company had generated
cumulative profits of approximately $18.4 million. Although the Company has
experienced a significant percentage growth in sales and gross profit from 1993
through December 31, 1997, the Company does not believe prior growth rates are
indicative of future operating results. Due to the Company's limited operating
history and resources, among other factors, there can be no assurance that
profitability or significant revenues on a quarterly or annual basis will occur
in the future. There can be no assurance that the Company's revenues will
continue to remain at or increase from the levels experienced in recent
quarters, or that sales will not decline. The Company intends, however, to
continue to invest significant amounts in its operations, particularly to
support product development and the marketing and sales of recently introduced
products and services, and operating expenses will continue to increase
significantly in absolute dollars. If the Company's sales do not correspondingly
increase, the Company's results of operations would be materially adversely
affected. Accordingly, there can be no assurance that the Company will achieve
profitability in future periods.

     Recently, the Company has significantly expanded the scale of its
operations to support the increases in its sales levels and to address critical
infrastructure and other requirements. This expansion has included the leasing
of additional space, the opening of branch offices and subsidiaries in the
United Kingdom, Germany and Singapore, the acquisitions of all or majority
interests in Geritel S.p.A. ("Geritel"), Atlantic Communication Sciences, Inc.
("ACS"), Technosystem S.p.A. ("Technosystem"), Columbia Spectrum Management L.P.
("CSM"), CRC, Telesys (UK) Limited ("Telesys"), RT Masts and Telematics,
significant investments in research and development to support product
development and services, and the hiring of additional personnel in all
functional areas, including in sales and marketing, finance, manufacturing and
operations. The Company anticipates that its operating expenses will continue to
increase significantly. If the Company's sales do not correspondingly increase,
the Company's results of operations would be materially adversely affected.

YEARS ENDED 1997, 1996 AND 1995

     Sales. Sales consist of revenues from radio systems and related software
tools and service offerings. The Company generated revenues from the sale of its
38 GHz radio systems commencing in October 1993, 50 GHz radio systems commencing
in September 1994, 23 GHz radio systems commencing in January 1995, 15 GHz radio
systems commencing in June 1996, 2.4 and 5.7 GHz spread spectrum radio systems
commencing in September 1996 (through the acquisition of ACS), 13 GHz radio
systems commencing in November 1996, 26 GHz radio system commencing in July
1997, 7 and 18 GHz radio systems commencing in September 1997 and service
offerings in March 1997. In 1997, 1996 and 1995, sales were approximately $220.7
million, $121.0 million, and $64.5 million, respectively. The increase in sales
was primarily due to increased volume of 38 and 23 GHz radio systems to new and
existing customers and, to a lesser extent, sales from products acquired in
recent acquisitions, and from service offerings. There can be no assurance that
sales of the Company's 

                                      22.
<PAGE>
 
radio systems or service will increase or that such systems or service will
achieve market acceptance. The Company provides to its customers significant
volume price discounts, which are expected to lower the average selling price of
a particular product line as more units are sold. In addition, the Company
expects that the average selling price of a particular product line will also
decline as such product matures, and as competition increases in the future.
Accordingly, the Company's ability to maintain or increase sales will depend
upon many factors, including its ability to increase unit sales volumes of its
systems and to introduce and sell systems at prices sufficient to compensate for
reduced revenues resulting from declines in the average selling price of the
Company's more mature products. To date, most of the Company's sales have been
made to customers located outside the United States. For risk factors associated
with customer concentration, declining average selling prices, results of
operations and international sales, please see "Certain Factors Affecting
Operating Results -- Significant Customer Concentration," "--Declining Average
Selling Prices," "--Significant Fluctuations in Results of Operations" and "--
International Operations; Risks of Doing Business in Developing Countries."

     Gross Profit. The Company's cost of sales consists primarily of costs
related to materials, labor and overhead. In 1997, 1996 and 1995, gross profit
was $91.5 million, $46.9 million and $27.0 million, respectively, or 41.4%,
38.8% and 41.9% of sales, respectively. The improvement in gross profit as a
percentage of sales from 1996 to 1997 was due to product design improvements and
economies of scale, but there can be no assurance that such improvements will
continue. The decrease of gross profit percentage from 1995 to 1996 was due to
new product introductions in the first and third quarters and related production
inefficiencies.

     The Company has an ongoing program to reduce the costs of manufacturing its
radio systems. As part of this program, the Company has been attempting to
achieve cost reductions principally through engineering and manufacturing
improvements, production economies and utilization of third party subcontractors
for the manufacture of the Company's radio systems and certain components and
subassemblies used in the systems. The Company also is implementing other cost
reduction programs in an effort to maintain gross margins in the future. There
can be no assurance that the Company's ongoing or future programs can be
accomplished or that they will increase gross profits. For risk factors
associated with gross profit, please see "Certain Factors Affecting Operating
Results -- Significant Fluctuations in Results of Operations," "--Declining
Average Selling Prices" and "--No Assurance of Product Quality, Performance and
Reliability."

     Research and Development. Expenses consist primarily of costs associated
with personnel and equipment. The Company's research and development activities
include the development of additional frequencies and varying operating features
and related software tools. In accordance with Financial Accounting Standards
Board Statement No. 86, the Company's policy is to capitalize internal software
development costs on a project at the time when the technological feasibility of
such project has been achieved. The Company's software development costs subject
to capitalization have not been significant to date and, as a result, have been
expensed during the periods incurred.

     In 1997, 1996 and 1995, research and development expenses were
approximately $29.1 million, $20.2 million and $12.3 million, respectively. The
increase in research and development expenses was due to increased staffing as
the Company concentrated on new product development, including costs associated
with a new product development by CRC beginning in 1996. The Company intends to
continue to invest significant resources to continue the development of new
systems and enhancements (including additional frequencies and varying operating
features and related software tools) and expects that research and development
expenses in absolute dollars in 1998 will continue to increase as compared to
1997.

     Selling and Marketing. Expenses consist of salaries of certain personnel,
investments in international operations, sales commissions, travel expenses,
customer service and support expenses and costs related to advertising and trade
shows. In 1997, 1996 and 1995, sales and marketing expenses were $15.7 million,
$7.5 million and $4.8 million, respectively. The increase in selling and
marketing expense is due to the expansion of the Company's domestic and
international markets. The Company intends to continue to invest significant
resources to expand its sales and marketing efforts, including the hiring of
additional personnel, and to establish the infrastructure necessary to support
future operations. The Company expects that such expenses in absolute dollars in
1998 will continue to increase as compared to 1997.

     General and Administrative. Expenses consist primarily of salaries and
other expenses for management, finance, accounting, legal and other professional
services. In 1997, 1996 and 1995, general and administrative expenses were $16.9
million, $10.3 million and $5.6 million, respectively. The increase in general
and administrative expenses of $6.6 million from 1996 to 1997 is related to
expansion of the Company's business as well as goodwill amortization associated
with acquisitions of Geritel, ACS, Technosystem and CSM. The goodwill is
amortized over the estimated life of acquired assets. The Company expects
general and administrative expenses to continue to increase in absolute dollars
in 1998 as compared to 1997, as the Company continues to expand its operations
and acquire companies. The Company also has incurred and 

                                      23.
<PAGE>
 
expects to continue to incur additional significant ongoing expenses as a
publicly owned company related to legal, accounting and other administrative
services and expenses.

     Interest and Other Income (Expense), Net. Interest and other income
(expense), net consists primarily of interest income generated from the
investment of cash received from financing activities in 1997, 1996 and 1995,
partially offset by interest expense accrued on the Company's bank line of
credit and equipment lease lines. In 1997, 1996 and 1995, interest and other
income (expense), net were $0.2 million, $0.9 million and $0.2 million,
respectively. Through fiscal 1997, contracts negotiated in foreign currencies
have been limited to British pound sterling contracts, and any impact due to
currency fluctuations has been insignificant. However, the Company may in the
future be exposed to the risk of foreign currency gains or losses depending upon
the magnitude of a change in the value of a local currency in an international
market. The Company has entered into foreign currency hedging transactions to
reduce exposure to foreign exchange risks. As of December 31, 1997, the Company
had forward exchange contracts valued at approximately $21.9 million.

     Income Tax Provision. The Company's effective tax rates for 1997, 1996 and
1995 were 36.9%, 9.7% and 17.0% respectively.  The Company's effective tax rate
is less than the combined federal and state statutory rate due principally to
net operating loss credit carryforwards available to offset taxable income. As
a result of exhausting the net operation loss and the credit carryover, as
well as the expansion of the operations into Europe where the Company is taxed
at a higher rate, the Company expects the 1997 effective tax rate to reflect
the future results.

LIQUIDITY AND CAPITAL RESOURCES

     Since its inception in August 1991, the Company has financed its operations
and met its capital requirements through net proceeds of approximately $89.5
million from the Company's initial and two follow-on public offerings of its
Common Stock, three preferred stock financings aggregating approximately $17.2
million, a convertible debt offering with net proceeds of approximately $97.5
million and borrowings under its bank lines of credit and equipment lease
arrangements.

     In 1997, the Company used approximately $12.5 million in operating
activities, primarily due to increases in accounts receivable, prepaid expenses,
other accrued liabilities, other assets, and inventory of $19.4 million, $1.7
million, $4.7 million, $5.1 million and $20.8 million, respectively, and a
decrease in accounts payable, notes receivable, income taxes payable, and
accrued employee benefits of $4.4 million, $1.8 million, $3.9 million and $2.0
million, respectively. These uses of cash were partially offset by net income
of $18.9 million and depreciation and amortization expense of $8.2 million.

     During 1997, the Company expended approximately $27.8 million in investing
activities consisting of approximately $3.1 million to purchase Technosystem and
$7.8 million to purchase CSM, and $16.9 million to acquire capital equipment.

     In 1997, the Company generated approximately $88.1 million in financing its
activities. The Company received approximately $97.5 million from its
convertible debt offering, and approximately $4.0 million from issuing Common
Stock pursuant to the Company's stock option and employee stock purchase plans.
This was partially offset by payment of approximately $12.7 million to retire
borrowing under the bank line of credit and approximately $0.7 million to retire
a portion of the bank debt of Technosystem and Geritel.

     At December 31, 1997, the Company had working capital of approximately
$174.6 million. In recent quarters, most of the Company's sales have been
realized near the end of each quarter, resulting in a significant investment in
accounts receivable at the end of the quarter. The Company expects that its
investments in accounts receivable and inventories will continue to represent a
significant portion of working capital. Significant investments in accounts
receivable and inventories may subject the Company to increased risks which
could materially adversely affect the Company's business, financial condition
and results of operations.

     The Company's principal sources of liquidity as of December 31, 1997
consisted of approximately $88.1 million of cash and cash equivalents. In
addition, the Company had a $25.0 million line of credit facility with Union
Bank of California. Borrowings under the line was unsecured and bore interest at
either a base interest rate or a variable interest rate. The agreement required
the Company to comply with certain financial covenants including the maintenance
of specified minimum ratios. At November 10, 1997, the Company terminated the
line of credit. The Company's principal sources of liquidity as of December 31,
1996 consisted of approximately $42.2 million of cash and cash equivalents

     At present, the Company does not have any material commitments for capital
equipment purchases. However, the Company's future capital requirements will
depend upon many factors, including the development of new radio systems and
related software tools, potential acquisitions, the extent and timing of
acceptance of the Company's radio systems in the market, requirements to
maintain adequate manufacturing facilities, working capital requirements for the
Company's 

                                      24.
<PAGE>
 
acquired entities, the progress of the Company's research and development
efforts, expansion of the Company's marketing and sales efforts, the Company's
results of operations and the status of competitive products. The Company
believes that cash and cash equivalents on hand, cash flow from operations, if
any, and funds available from the Company's bank line of credit will be adequate
to fund its operations in the ordinary course of business for at least the next
twelve months. There can be no assurance, however, that the Company will not
require additional financing prior to such date to fund its operations. The
Company has in the past and may from time to time in the future sell its
receivables, as part of an overall customer financing program, with immaterial
recourse to the Company. There can be no assurance that the Company will be able
to locate parties to purchase such receivables on acceptable terms, or at all.
To the extent that the Company's financial resources are insufficient to fund
the Company's activities, additional funds will be required. There can be no
assurance that any additional financing will be available to the Company on
acceptable terms, or at all, when required by the Company. If additional funds
are raised by issuing equity securities, further dilution to the existing
stockholders will result. If adequate funds are not available, the Company may
be required to delay, scale back or eliminate one or more of its research and
development or manufacturing programs, cease its acquisition activities or
obtain funds through arrangements with partners or others that may require the
Company to relinquish rights to certain of its technologies or potential
products or other assets that the Company would not otherwise relinquish.
Accordingly, the inability to obtain such financing could have a material
adverse effect on the Company's business, financial condition and results of
operations. For risk factors associated with the Company's future capital
requirements, please see "Certain Factors Affecting Operating Results -- Future
Capital Requirements."

ACQUISITIONS

     On February 24, 1997, the Company acquired 100% of the equity of
Technosystem, a Rome, Italy-based company, with additional operations in Poland
for $3.3 million. The Company paid $2.6 million in cash and an additional
payment of $0.7 million will be due on March 31, 1998, subject to certain
indemnification obligations of the former Technosystem security holders as set
forth in the securities purchase agreement. Technosystem designs, manufactures
and markets equipment for transmitters and transponders for television and radio
broadcasting. The range of products include audio/video modulators, converters,
amplifiers, transponders, transmitters and microwave links. The Company
accounted for the acquisition based on the purchase method of accounting and the
results of operations of Technosystem are included in the Company's consolidated
results for all periods subsequent to the date of acquisition.

     On March 7, 1997, the Company acquired substantially all of the assets of
CSM, a Vienna, Virginia-based company, for $8.0 million in cash and 796,612
shares of Common Stock valued at $14.5 million. In addition, the former partners
of CSM may receive up to an additional $1,500,000 in cash (as part of such $8.0
million amount) over the next two years, subject to the satisfaction of certain
indemnification obligations, and the 796,612 shares issued to the former
partners may either increase or decrease in an amount of up to 15%, as
determined pursuant to the terms of the asset purchase agreement. CSM provides
turnkey relocation services for microwave paths over spectrum allocated by the
Federal Communications Commission for Personal Communications Services and other
emerging technologies. The Company accounted for the acquisition based on the
purchase method of accounting, and the results of operations of CSM are included
in the Company's consolidated results for all periods subsequent to the date of
acquisition.

     On May 29, 1997, the Company acquired all of the outstanding shares of
capital stock of CRC, a provider of integrated network access devices to network
service providers, in exchange for 1,502,956 shares of P-Com Common Stock that
were issued or are issuable to former CRC security holders in a stock-for-stock
merger. CRC, located in Fair Lawn, New Jersey, manufactures products used by the
communications industry to connect end user sites to a range of communications
services. CRC's NetPath product line enables network service providers to offer
their customers a migration path from entry-level data services to cost-
effective integrated delivery of voice, video and Internet access. The NetPath
product line also supports the network service provider's introduction of new
technologies including asynchronous transfer mode and frame relay.

     On November 27, 1997, the Company acquired all of the outstanding shares of
capital stock of RT Masts, a United Kingdom-based company and Telematics, a
Virginia-based company, in exchange for 766,151 and 248,215 shares of P-Com
Common Stock, respectively. RT Masts, located in Wellingborough,
Northhamptonshire, U.K. and Telematics, located in Herndon, Virginia, supply,
install and maintain telecommunications systems and structures including
antennas covering high frequency, medium frequency and microwave systems. Both
companies manage the construction of radio system sites, as well as construction
of towers and install radios and antennas at system sites.

     There can be no assurance that any operations of the Company's acquired
entities will be profitable after the acquisitions.  Moreover, there can be no
assurance that the anticipated benefits of such acquisitions will be realized.

process of integrating the operations of the Company's acquired entities into
the Company's operations may result in unforeseen operating difficulties and
could absorb significant management attention, expenditures and reserves that
would otherwise be available for the ongoing development of the Company's
business.


CERTAIN FACTORS AFFECTING OPERATING RESULTS

SIGNIFICANT FLUCTUATIONS IN RESULTS OF OPERATIONS

     The Company has experienced and will in the future continue to experience
significant fluctuations in sales, gross margins and operating results. The
procurement process for most of the Company's current and potential customers is
complex and lengthy, and the timing and amount of sales is difficult to predict
reliably. The sale and implementation of the Company's products and services
generally involves a significant commitment of the Company's senior management,
sales force and other resources. The sales cycle for the Company's products and
services typically involves a significant technical evaluation and commitment of
cash and other resources, with the attendant delays frequently associated with,
among other things: (i) existing and potential customers' seasonal purchasing
and budgetary cycles; (ii) educating customers as to the potential applications
of, and product-life cost savings associated with, using the Company's products
and services; (iii) complying with customers' internal procedures for approving
large expenditures and evaluating and accepting new technologies that affect key
operations; (iv) complying with governmental or other regulatory standards; (v)
difficulties associated with each customer's ability to secure financing; and
(vi) negotiating purchase and service terms for each sale. Orders for the
Company's products have typically been strongest towards the end of the calendar
year, with a reduction in shipments occurring during the summer months, as
evidenced in the third quarter of fiscal year 1997, due primarily to the
inactivity of the European market, the Company's major current customer base, at
such time. To the extent such seasonality continues, the Company's results of
operations will fluctuate from quarter to quarter.

     In addition, a single customer's order scheduled for shipment in a quarter
can represent a significant portion of the Company's potential sales for such
quarter. There can be no assurance that the Company will be able to obtain such
large orders from single customers in the future. The Company has at times
failed to receive expected orders, and delivery schedules have been deferred as
a result of changes in customer requirements and commitments, among other
factors. As a result, the Company's operating results for a particular period
have in the past been and will in the future be materially adversely affected by
a delay, rescheduling or cancellation of even one purchase order. Much of the
anticipated growth in telecommunications infrastructure, if any, is expected to
result from the entrance of new service providers, many of which do not have the
financial resources of existing service providers. To the extent these new
service providers are unable to adequately finance their operations, they may
cancel orders. Moreover, purchase orders are often received and accepted
substantially in advance of shipment, and the failure to reduce actual costs to
the extent anticipated or an increase in anticipated costs before shipment could
materially adversely affect the gross margins for such orders, and as a result,
the Company's results of operations. Moreover, most of the Company's backlog
scheduled for shipment in the twelve months subsequent to December 31, 1997 can
be canceled since orders are often made substantially in advance of shipment,
and the Company's contracts typically provide that orders may be canceled with
limited or no penalties. As a result, backlog is not necessarily indicative of
future sales for any particular period. In addition, the Company's customers
have increasingly been requiring shipment of products at the time of ordering
rather than submitting purchase orders far in advance of expected dates of
product shipment. Furthermore, most of the Company's sales in recent quarters
have been realized near the end of each quarter. Accordingly, a delay in a
shipment near the end of a particular quarter, as the Company has been
experiencing recently, due to, for example, an unanticipated shipment
rescheduling, a cancellation or deferral by a customer, competitive or economic
factors, unexpected manufacturing or other difficulties, delays in deliveries of
components, subassemblies or services by suppliers, or the failure to receive an
anticipated order, may cause sales in a particular quarter to fall significantly
below the Company's expectations and may materially adversely affect the
Company's operating results for such quarter.

     In connection with its efforts to ramp-up production of products and
services, the Company expects to continue to make substantial capital
investments in equipment and inventory, recruit and train additional personnel
and possibly invest in additional manufacturing facilities. The Company
anticipates that these expenditures will be made in advance of, and in
anticipation of, increased sales and, therefore, that its gross margins will be
adversely affected from time-to-time due to short-term inefficiencies associated
with the addition of equipment and inventory, personnel or facilities, and that
each cost category may increase as a percentage of revenues from time-to-time on
a periodic basis. In addition, as the Company's customers increasingly require
shipment of products at the time of ordering, the Company must forecast 

                                      26.
<PAGE>
 
demand for each quarter and build up inventory accordingly. Such increases in
inventory could materially adversely affect the Company's operations, if such
inventory were not utilized or becomes obsolete.

     A large portion of the Company's expenses are fixed and difficult to reduce
should revenues not meet the Company's expectations, thus magnifying the
material adverse effect of any revenue shortfall. Furthermore, announcements by
the Company or its competitors of new products, services and technologies could
cause customers to defer or cancel purchases of the Company's systems and
services, which would materially adversely affect the Company's business,
financial condition and results of operations. Additional factors that have
caused and will continue to cause the Company's sales, gross margins and results
of operations to vary significantly from period to period include: new product
introductions and enhancements, including related costs; the Company's ability
to manufacture and produce sufficient volumes of systems and meet customer
requirements; manufacturing capacity, efficiencies and costs; mix of sales
through direct efforts or through distributors or other third parties; mix of
systems and related software tools sold and services provided; operating and new
product development expenses; product discounts; accounts receivable collection,
in particular those acquired in recent acquisitions, especially outside of the
United States; changes in pricing by the Company, its customers or suppliers;
inventory write-offs, as the Company recently experienced in the second and
third quarters for a relatively immaterial amount in each such quarter, which
the Company may experience again in the future; inventory obsolescence; natural
disasters; market acceptance by the Company's customers and the timing of
availability of new products and services by the Company or its competitors;
acquisitions, including costs and expenses; usage of different distribution and
sales channels; fluctuations in foreign currency exchange rates; delays or
changes in regulatory approval of its systems and services; warranty and
customer support expenses; customization of systems; and general economic and
political conditions. In addition, the Company's results of operations have been
and will continue to be influenced significantly by competitive factors,
including the pricing and availability of, and demand for, competitive products
and services. All of the above factors are difficult for the Company to
forecast, and these or other factors could materially adversely affect the
Company's business, financial condition and results of operations. As a result,
the Company believes that period-to-period comparisons are not necessarily
meaningful and should not be relied upon as indications of future performance.
Due to all of the foregoing factors, it is likely that in some future quarter
the Company's operating results will be below the expectations of public market
analysts and investors. In such event, the price of the Company's Common Stock
may be materially adversely affected.

SIGNIFICANT CUSTOMER CONCENTRATION

     For the year ended December 31, 1997, approximately seventy-five customers
accounted for substantially all of the Company's sales, and two customers, each
of which individually accounted for over 10% of the Company's 1997 sales,
accounted for over 27% of the Company's sales. In 1996, the Company had five
customers which individually accounted for over 10% of the Company's sales.
Sales to Orange Personal Communications Ltd. and WinStar accounted for
approximately 16% and 11% of the Company's sales, respectively, in 1997. Sales
to Orange Personal Communications Ltd., WinStar, Bosch Telecom GmbH, Ericsson
Limited and ART accounted for approximately 18%, 12%, 11%, 11% and 11% of the
Company's sales, respectively, in 1996. As of December 31, 1997, seven customers
accounted for over 64% of the Company's backlog scheduled for shipment in the
twelve months subsequent to December 31, 1997. The Company anticipates that it
will continue to sell its products and services to a changing but still
relatively small group of customers. Several of the Company's subsidiaries are
dependent on one or a few customers. Some companies implementing new networks
are at early stages of development and may require additional capital to fully
implement their planned networks. The Company's ability to achieve sales in the
future will depend in significant part upon its ability to obtain and fulfill
orders from, maintain relationships with and provide support to existing and new
customers, to manufacture systems in volume on a timely and cost-effective basis
and to meet stringent customer performance and other requirements and shipment
delivery dates, as well as the condition, working capital availability and
success of its customers. As a result, any cancellation, reduction or delay in
orders by or shipments to any customer, as a result of manufacturing or supply
difficulties or otherwise, or the inability of any customer to finance its
purchases of the Company's products or services, as has been the case with
certain customers historically, may materially adversely affect the Company's
business, financial condition and results of operations. In addition, financial
difficulties of any existing or potential customers may limit the overall demand
for the Company's products and services (for example, certain potential
customers in the telecommunications industry have been reported to have
undergone financial difficulties and may therefore limit their future orders).
In addition, acquisitions in the communications industry are common, which
further concentrates the customer base and may cause orders to be delayed or
cancelled. There can be no assurance that the Company's sales will increase in
the future or that the Company will be able to support or attract customers.

                                      27.

ACQUISITIONS

     Since April 1996, the Company has acquired eight complementary companies
and businesses. Integration of these companies into the Company's business is
currently ongoing, and no assurance may be made that the Company will be able to
successfully complete this process. Risks commonly encountered in such
transactions include the difficulty of assimilating the operations and personnel
of the combined companies, the potential disruption of the Company's ongoing
business, the inability to retain key technical and managerial personnel, the
inability of management to maximize the financial and strategic position of the
Company through the integration of acquired businesses, additional expenses
associated with amortization of acquired intangible assets, dilution of existing
stockholders, the maintenance of uniform standards, controls, procedures, and
policies, the impairment of relationships with employees and customers as a
result of any integration of new personnel, risks of entering markets in which
the Company has no or limited direct prior experience, and operating companies
in different geographical locations with different cultures. All of the
Company's acquisitions to date (the "Acquisitions"), except the acquisitions of
CRC, RT Masts, and Telematics have been accounted for under the purchase method
of accounting, and as a result, a significant amount of goodwill is being
amortized as set forth in the Company's consolidated financial statements. This
amortization expense may have a significant effect on the Company's financial
results. There can be no assurance that the Company will be successful in
overcoming these risks or any other problems encountered in connection with such
acquisitions, or that such transactions will not materially adversely affect the
Company's business, financial condition, or results of operations.

     As part of its overall strategy, the Company plans to continue to acquire
or invest in complementary companies, products or technologies and to enter into
joint ventures and strategic alliances with other companies. The Company is
currently pursuing numerous acquisitions; however, except as set forth in this
Prospectus, no material acquisition has become the subject of any definitive
agreement, letter of intent or agreement in principle. The Company is unable to
predict whether and when any prospective acquisition candidate will become
available or the likelihood that any acquisition will be completed. The Company
competes for acquisition and expansion opportunities with many entities that
have substantially greater resources than the Company. There can be no assurance
that the Company will be able to successfully identify suitable acquisition
candidates, complete acquisitions, or expand into new markets. Once integrated,
acquired businesses may not achieve comparable levels of revenues,
profitability, or productivity as the existing business of the Company or
otherwise perform as expected. In addition, as commonly occurs with mergers of
technology companies, during the pre-merger and integration phases, aggressive
competitors may undertake formal initiatives to attract customers and to recruit
key employees through various incentives. If the Company proceeds with one or
more significant acquisitions in which the consideration consists of cash, a
substantial portion of the Company's available cash could be used to consummate
the acquisitions. Many business acquisitions must be accounted for as a purchase
for financial reporting purposes. Most of the businesses that might become
attractive acquisition candidates for the Company are likely to have significant
goodwill and intangible assets, and acquisition of these businesses, if
accounted for as a purchase, would typically result in substantial amortization
of goodwill charges to the Company. The occurrence of any of these events could
have a material adverse effect on the Company's workforce, business, financial
condition and results of operations.

DEPENDENCE ON CONTRACT MANUFACTURERS; RELIANCE ON SOLE OR LIMITED SOURCES OF
SUPPLY

     The Company's internal manufacturing capacity is very limited. The Company
utilizes contract manufacturers such as Remec, Inc., Sanmina Corporation, SPC
Electronics Corp., GSS Array Technology, Celeritek, Inc. and Senior Systems
Technology, Inc. to produce its systems, components and subassemblies and
expects to rely increasingly on these and other manufacturers in the future. The
Company also relies on outside vendors to manufacture certain other components
and subassemblies. There can be no assurance that the Company's internal
manufacturing capacity and that of its contract manufacturers will be sufficient
to fulfill the Company's orders. Failure to manufacture, assemble and ship
systems and meet customer demands on a timely and cost-effective basis could
damage relationships with customers and have a material adverse effect on the
Company's business, financial condition and operating results. Certain necessary
components, subassemblies and services necessary for the manufacture of the
Company's systems are obtained from a sole supplier or a limited group of
suppliers. In particular, Eltel Engineering S.r.L. and Associates, Milliwave,
Scientific Atlanta and Xilinx, Inc. each are sole source or limited source
suppliers for critical components used in the Company's radio systems.

     The Company's reliance on contract manufacturers and on sole suppliers or a
limited group of suppliers and the Company's increasing reliance on contract
manufacturers and suppliers involves several risks, many of which the Company
has been experiencing, including an inability to obtain an adequate supply of
finished products and required 

                                      28.
<PAGE>
 
components and subassemblies, and reduced control over the price, timely
delivery, reliability and quality of finished products, components and
subassemblies. The Company does not have long-term supply agreements with most
of its manufacturers or suppliers. Manufacture of the Company's products and
certain of these components and subassemblies is an extremely complex process,
and the Company has from time to time experienced and may in the future continue
to experience problems in the timely delivery and quality of products and
certain components and subassemblies from vendors. Certain of the Company's
suppliers have relatively limited financial and other resources. Any inability
to obtain timely deliveries of components and subassemblies of acceptable
quality or any other circumstance that would require the Company to seek
alternative sources of supply, or to manufacture its finished products or such
components and subassemblies internally, could delay the Company's ability to
ship its systems, which could damage relationships with current or prospective
customers and have a material adverse effect on the Company's business,
financial condition and results of operations.

NO ASSURANCE OF SUCCESSFUL EXPANSION OF OPERATIONS; MANAGEMENT OF GROWTH

     Recently, the Company has significantly expanded the scale of its
operations to support increased sales and to address critical infrastructure and
other requirements. This expansion has included the leasing of additional space,
the opening of branch offices and subsidiaries in the United Kingdom, Italy,
Germany and Singapore, the opening of design centers and manufacturing
operations throughout the world, the acquisition of a significant amount of
inventory (the Company's inventory increased from approximately $32.9 million at
December 31, 1996 to approximately $58.0 million at December 31, 1997) and
accounts receivable, recent acquisitions, significant investments in research
and development to support product development and services, including the
recently introduced products and the development of point-to-multipoint systems,
and the hiring of additional personnel in all functional areas, including in
sales and marketing, manufacturing and operations and finance, and has resulted
in significantly higher operating expenses. Currently, the Company is devoting
significant resources to the development of new products and technologies and is
conducting evaluations of these products and will continue to invest significant
additional resources in plant and equipment, inventory, personnel and other
costs, to begin production of these products and to provide the marketing and
administration, if any, required to service and support these new products.
Accordingly, there can be no assurance that gross profit margin and inventory
levels will not be adversely impacted in the future by start-up costs associated
with the initial production and installation of these new products. These start-
up costs include, but are not limited to, additional manufacturing overhead,
additional allowance for doubtful accounts, inventory and warranty reserve
requirements and the creation of service and support organizations. In addition,
the increases in inventory on hand for new product development and customer
service requirements may increase the risk of inventory write-offs. As a result,
the Company anticipates that its operating expenses will continue to increase
significantly. If the Company's sales do not correspondingly increase, the
Company's results of operations would be materially adversely affected. See "--
Limited Operating History."

     Expansion of the Company's operations and its acquisitions have caused and
are continuing to impose a significant strain on the Company's management,
financial, manufacturing and other resources and have disrupted the Company's
normal business operations. The Company's ability to manage the recent and any
possible future growth, should it occur, will depend upon a significant
expansion of its manufacturing, accounting and other internal management systems
and the implementation and subsequent improvement of a variety of systems,
procedures and controls, including improvements relating to inventory control.
For a number of reasons, the Company has not been able to fully consolidate and
integrate the operations of certain acquired businesses. This inability may
cause inefficiencies, additional operational complexities and expenses and
greater risks of billing delays, inventory write-offs and financial reporting
difficulties. The Company must establish and improve a variety of systems,
procedures and controls to more efficiently coordinate its activities in its
acquired (and to be acquired) companies and their facilities in Rome and Milan,
Italy, France, Poland, the United Kingdom, New Jersey, Florida, Virginia and
elsewhere. There can be no assurance that significant problems in these areas
will not re-occur. Any failure to expand these areas and implement and improve
such systems, procedures and controls, including improvements relating to
inventory control, in an efficient manner at a pace consistent with the
Company's business could have a material adverse effect on the Company's
business, financial condition and results of operations. In particular, the
Company must successfully manage the transition to higher internal and external
volume manufacturing, including the establishment of adequate facilities, the
control of overhead expenses and inventories, the development, introduction,
marketing and sales of new products, the management and training of its employee
base, the integration and coordination of a geographically and ethnically
diverse group of employees and the monitoring of its third party manufacturers
and suppliers. Although the Company has substantially increased the number of
its manufacturing personnel and significantly expanded its internal and external
manufacturing capacity, there can be no assurance that the 

                                      29.
<PAGE>
 
Company will not experience manufacturing or other delays or problems that could
materially adversely affect the Company's business, financial condition or
results of operations.

     In this regard, any significant sales growth will be dependent in
significant part upon the Company's expansion of its marketing, sales,
manufacturing and customer support capabilities. This expansion will continue to
require significant expenditures to build the necessary infrastructure. There
can be no assurance that the Company's attempts to expand its marketing, sales,
manufacturing and customer support efforts will be successful or will result in
additional sales or profitability in any future period. As a result of the
expansion of its operations and the significant increase in its operating
expenses, as well as the difficulty in forecasting revenue levels, the Company
will continue to experience significant fluctuations in its revenues, costs, and
gross margins, and therefore its results of operations.

LIMITED OPERATING HISTORY

     P-Com was founded in August 1991 and was in the development stage until
October 1993 when it began commercial shipments of its first product. From
inception to the end of fiscal 1997, the Company generated a cumulative net
profit of approximately $18.4 million. From October 1993 through December 31,
1997, the Company generated sales of approximately $454.9 million, of which
$220.7 million, or 49% of such amount, was generated in the year ended December
31, 1997. The Company does not believe recent growth rates are indicative of
future operating results. Due to the Company's limited operating history and
limited resources, among other factors, there can be no assurance that
profitability or significant revenues on a quarterly or annual basis will occur
in the future. During both 1996 and 1997, both the Company's sales and operating
expenses increased more rapidly than the Company had anticipated. There can be
no assurance that the Company's revenues will continue to remain at or increase
from the levels experienced in 1996 or 1997 or that sales will not decline. The
Company intends to continue to invest significant amounts in its operations,
particularly to support product development and the marketing and sales of
recently introduced products, and operating expenses will continue to increase
significantly in absolute dollars. If the Company's sales do not correspondingly
increase, the Company's results of operations would be materially adversely
affected. Accordingly, there can be no assurance that the Company will achieve
profitability in future periods. The Company is subject to all of the risks
inherent in the operation of a new business enterprise, and there can be no
assurance that the Company will be able to successfully address these risks.

DECLINING AVERAGE SELLING PRICES

     The Company believes that average selling prices and gross margins for its
systems and services will decline in the long term as such systems mature, as
volume price discounts in existing and future contracts take effect and as
competition intensifies, among other factors. To offset declining average
selling prices, the Company believes that it must successfully introduce and
sell new systems on a timely basis, develop new products that incorporate
advanced software and other features that can be sold at higher average selling
prices and reduce the costs of its systems through contract manufacturing,
design improvements and component cost reduction, among other actions. To the
extent that new products are not developed in a timely manner, do not achieve
customer acceptance or do not generate higher average selling prices, and the
Company is unable to offset declining average selling prices, the Company's
gross margins will decline, and such decline will have a material adverse effect
on the Company's business, financial condition and results of operations.

TRADE ACCOUNT RECEIVABLES

     The Company is subject to credit risk in the form of trade account
receivables. The Company may in certain circumstances be unable to enforce a
policy of receiving payment within a limited number of days of issuing bills,
especially in the case of customers that are in the early phases of business
development. In addition, many of the Company's foreign customers are granted
longer terms than those typically existing in the United States. The Company has
experienced difficulties in the past in receiving payment in accordance with the
Company's policies, particularly from customers awaiting financing to fund their
expansion and from customers outside of the United States and the days
outstanding of receivables have increased recently. There can be no assurance
that such difficulties will not continue in the future, which could have a
material adverse effect on the Company's business, financial condition and
results of operations. The Company typically does not require collateral or
other security to support customer receivables.  The Company has in the past and
may from time to time in the future sell its receivables, as part of an overall
customer financing program, with immaterial recourse to the Company.  There can
be no assurance that the Company will be able to locate parties to purchase such
receivables on acceptable terms, or at all.  See "--Significant Fluctuations in
Results of Operations" and "--International Operations; Risks of Doing Business
in Developing Countries."

                                      30.
<PAGE>
 
NO ASSURANCE OF PRODUCT QUALITY, PERFORMANCE AND RELIABILITY

   The Company has limited experience in producing and manufacturing its systems
and contracting for such manufacture. The Company's customers require very
demanding specifications for quality, performance and reliability. There can be
no assurance that problems will not occur in the future with respect to the
quality, performance and reliability of the Company's systems or related
software tools. If such problems occur, the Company could experience increased
costs, delays in or cancellations or reschedulings of orders or shipments,
delays in collecting accounts receivable and product returns and discounts, any
of which would have a material adverse effect on the Company's business,
financial condition or results of operations. In addition, in order to maintain
its ISO 9001 registration, the Company periodically must undergo a
recertification assessment. Failure to maintain such registration could
materially adversely affect the Company's business, financial condition and
results of operations. The Company completed ISO 9001 registration for its
United Kingdom sales and customer support facility, its Geritel facility in
Italy in 1996, and its Technosystem facility in Italy in 1997 and other
facilities will also be attempting ISO 9001 registration. There can be no
assurance that such registration will be achieved.

UNCERTAINTY OF MARKET ACCEPTANCE

   The future operating results of the Company depend to a significant extent
upon the continued growth and increased availability and acceptance of
microcellular, PCN/PCS and wireless local loop access telecommunications
services in the United States and internationally. There can be no assurance
that the volume and variety of wireless telecommunications services or the
markets for and acceptance of such services will continue to grow, or that such
services will create a demand for the Company's systems. Because these markets
are relatively new, it is difficult to predict which segments of these markets
will develop and at what rate these markets will grow, if at all. If the short-
haul millimeter wave or spread spectrum microwave wireless radio market and
related services for the Company's systems fails to grow, or grows more slowly
than anticipated, the Company's business, financial condition and results of
operations would be materially adversely affected. In addition, the Company has
invested a significant amount of time and resources in the development of point-
to-multipoint radio systems. Should the point-to-multipoint radio market fail to
develop, or should the Company's products fail to gain market acceptance, the
Company's business, financial condition and results of operations could be
materially adversely affected. Certain sectors of the communications market will
require the development and deployment of an extensive and expensive
communications infrastructure. In particular, the establishment of PCN/PCS
networks will require very large capital expenditures. There can be no assurance
that communications providers have the ability to or will make the necessary
investment in such infrastructure or that the creation of this infrastructure
will occur in a timely manner. Moreover, one potential application of the
Company's technology, use of the Company's systems in conjunction with the
provision by wireless telecommunications service providers of alternative
wireless access in competition with the existing wireline local exchange
providers, is dependent on the pricing of wireless telecommunications services
at rates competitive with those charged by wireline telephone companies. Rates
for wireless access are currently substantially higher than those charged by
wireline companies, and there can be no assurance that rates for wireless access
will generally be competitive with rates charged by wireline companies. If
wireless access rates are not competitive, consumer demand for wireless access
will be materially adversely affected. If the Company allocates its resources to
any market segment that does not grow, it may be unable to reallocate its
resources to other market segments in a timely manner, which may curtail or
eliminate its ability to enter such market segments.

   Certain of the Company's current and prospective customers are currently
delivering products and technologies which utilize competing transmission media
such as fiber optic and copper cable, particularly in the local loop access
market. To successfully compete with existing products and technologies, the
Company must, among many actions, offer systems with superior price/performance
characteristics and extensive customer service and support, supply such systems
on a timely and cost-effective basis in sufficient volume to satisfy such
prospective customers' requirements and otherwise overcome any reluctance on the
part of such customers to transition to new technologies. Any delay in the
adoption of the Company's systems may result in prospective customers utilizing
alternative technologies in their next generation of systems and networks, which
would have a material adverse effect on the Company's business, financial
condition and results of operations. There can be no assurance that prospective
customers will design their systems or networks to include the Company's
systems, that existing customers will continue to include the Company's systems
in their products, systems or networks in the future, or that the Company's
technology will to any significant extent replace existing technologies and
achieve widespread acceptance in the wireless telecommunications market. Failure
to achieve or sustain commercial acceptance of the Company's currently available
radio systems or to develop other commercially acceptable radio systems would
materially adversely affect the Company's business, financial condition and
results of operations. In addition, there can be no assurance that industry
technical standards will remain the same or, if emerging 

                                      31.
<PAGE>
 
standards become established, that the Company will be able to conform to these
new standards in a timely and cost-effective manner.

INTENSELY COMPETITIVE INDUSTRY

   The wireless communications market is intensely competitive. The Company's
wireless-based radio systems compete with other wireless telecommunications
products and alternative telecommunications transmission media, including copper
and fiber optic cable. The Company has experienced increasingly intense
competition worldwide from a number of leading telecommunications companies that
offer a variety of competitive products and services and broader
telecommunications product lines, including Adtran, Inc., Alcatel Network
Systems, California Microwave, Inc., Digital Microwave Corporation, Ericsson
Limited, Harris Corporation-Farinon Division, Innova International Corp., Larus
Corporation, Nokia Telecommunications, Philips T.R.T. and Western Multiplex
Corporation, many of which have substantially greater installed bases, financial
resources and production, marketing, manufacturing, engineering and other
capabilities than the Company. The Company faces actual and potential
competition not only from these established companies, but also from start-up
companies that are developing and marketing new commercial products and
services. The Company may also face competition in the future from new market
entrants offering competing technologies. In addition, the Company's current and
prospective customers and partners, certain of which have access to the
Company's technology or under some circumstances are granted the right to use
the technology for purposes of manufacturing, have developed, are currently
developing or could develop the capability to manufacture products competitive
with those that have been or may be developed or manufactured by the Company.
The Company's results of operations may depend in part upon the extent to which
these customers elect to purchase from outside sources rather than develop and
manufacture their own radio systems. There can be no assurance that such
customers will rely on or expand their reliance on the Company as an external
source of supply for their radio systems. The principal elements of competition
in the Company's market and the basis upon which customers may select the
Company's systems include price, performance, software functionality, ability to
meet delivery requirements and customer service and support. Recently, certain
of the Company's competitors have announced the introduction of competitive
products, including related software tools and services, and the acquisition of
other competitors and competitive technologies. The Company expects its
competitors to continue to improve the performance and lower the price of their
current products and services and to introduce new products and services or new
technologies that provide added functionality and other features. New product
and service offerings and enhancements by the Company's competitors could cause
a significant decline in sales or loss of market acceptance of the Company's
systems, or make the Company's systems, services or technologies obsolete or
noncompetitive. The Company has experienced significant price competition, and
expects such competition to intensify, which may materially adversely affect its
gross margins and its business, financial condition and results of operations.
The Company believes that to be competitive, it will continue to be required to
expend significant resources on, among other items, new product development and
enhancements. In marketing its systems and services, the Company will face
competition from vendors employing other technologies and services that may
extend the capabilities of their competitive products beyond their current
limits, increase their productivity or add other features. There can be no
assurance that the Company will be able to compete successfully in the future.

REQUIREMENT FOR RESPONSE TO RAPID TECHNOLOGICAL CHANGE AND REQUIREMENT FOR
FREQUENT NEW PRODUCT INTRODUCTIONS

   The communications market is subject to rapid technological change, frequent
new product introductions and enhancements, product obsolescence, changes in
end-user requirements and evolving industry standards. The Company's ability to
be competitive in this market will depend in significant part upon its ability
to successfully develop, introduce and sell new systems and enhancements and
related software tools, including its point-to-multipoint systems currently
under development, on a timely and cost-effective basis that respond to changing
customer requirements. Recently, the Company has been developing point-to-
multipoint radio systems. Any success of the Company in developing new and
enhanced systems, including its point-to-multipoint systems currently under
development, and related software tools will depend upon a variety of factors,
including new product selection, integration of the various elements of its
complex technology, timely and efficient completion of system design, timely and
efficient implementation of manufacturing and assembly processes and its cost
reduction program, development and completion of related software tools, system
performance, quality and reliability of its systems and development and
introduction of competitive systems by competitors. The Company has experienced
and is continuing to experience delays from time to time in completing
development and introduction of new systems and related software tools,
including products acquired in the acquisitions. Moreover, there can be no
assurance that the Company will be successful in selecting, developing,
manufacturing and marketing new systems or enhancements or related software
tools. There can be no assurance that errors will not be 

                                      32.

found in the Company's systems after commencement of commercial shipments, which
could result in the loss of or delay in market acceptance, as well as
significant expenses associated with re-work of previously delivered equipment.
The inability of the Company to introduce in a timely manner new systems or
enhancements or related software tools that contribute to sales could have a
material adverse effect on the Company's business, financial condition and
results of operations.

INTERNATIONAL OPERATIONS; RISKS OF DOING BUSINESS IN DEVELOPING COUNTRIES

   Most of the Company's sales to date have been made to customers located
outside of the United States. In addition, to date, the Company has acquired two
Italy-based companies and two United Kingdom-based companies and the acquisition
of a company with substantial international operations is currently pending.
These companies currently sell their products and services primarily to
customers in Europe, the Middle East and Africa. The Company anticipates that
international sales will continue to account for a majority of its sales for the
foreseeable future. Historically the Company's international sales have been
denominated in British pounds sterling or United States currencies. With recent
acquisitions of foreign companies, certain of the Company's international sales
may be denominated in other foreign currencies. A decrease in the value of
foreign currencies relative to the United States dollar could result in losses
from transactions denominated in foreign currencies. With respect to the
Company's international sales that are United States dollar-denominated, such a
decrease could make the Company's systems less price-competitive and could have
a material adverse effect upon the Company's business, financial condition and
results of operations. The Company has in the past mitigated its currency
exposure to the British pound sterling through hedging measures. However, any
future hedging measures may be limited in their effectiveness with respect to
the British pound sterling and other foreign currencies. Additional risks
inherent in the Company's international business activities include changes in
regulatory requirements, costs and risks of localizing systems in foreign
countries, delays in receiving components and materials, availability of
suitable export financing, timing and availability of export licenses, tariffs
and other trade barriers, political and economic instability, difficulties in
staffing and managing foreign operations, branches and subsidiaries,
difficulties in managing distributors, potentially adverse tax consequences,
foreign currency exchange fluctuations, the burden of complying with a wide
variety of complex foreign laws and treaties and the difficulty in accounts
receivable collections. Many of the Company's customer purchase and other
agreements are governed by foreign laws, which may differ significantly from
U.S. laws. Therefore, the Company may be limited in its ability to enforce its
rights under such agreements and to collect damages, if awarded. There can be no
assurance that any of these factors will not have a material adverse effect on
the Company's business, financial condition and results of operations.

   International telephone companies are in many cases owned or strictly
regulated by local regulatory authorities. Access to such markets is often
difficult due to the established relationships between a government owned or
controlled telephone company and its traditional indigenous suppliers of
telecommunications equipment. The successful expansion of the Company's
international operations in certain markets will depend on its ability to
locate, form and maintain strong relationships with established companies
providing communication services and equipment in targeted regions. The failure
to establish regional or local relationships or to successfully market or sell
its products in international markets could significantly limit the Company's
ability to expand its operations and would materially adversely affect the
Company's business, financial condition and results of operations. The Company's
inability to identify suitable parties for such relationships, or even if such
parties are identified, to form and maintain strong relationships with such
parties could prevent the Company from generating sales of its products and
services in targeted markets or industries. Moreover, even if such relationships
are established, there can be no assurance that the Company will be able to
increase sales of its products and services through such relationships.

   Some of the Company's potential markets consist of developing countries that
may deploy wireless communications networks as an alternative to the
construction of a limited wired infrastructure. These countries may decline to
construct wireless telecommunications systems or construction of such systems
may be delayed for a variety of reasons, in which event any demand for the
Company's systems in those countries will be similarly limited or delayed. In
doing business in developing markets, the Company may also face economic,
political and foreign currency fluctuations that are more volatile than those
commonly experienced in the United States and other areas.

                                      33.

EXTENSIVE GOVERNMENT REGULATION

   Radio communications are subject to extensive regulation by the United States
and foreign laws and international treaties. The Company's systems must conform
to a variety of domestic and international requirements established to, among
other things, avoid interference among users of radio frequencies and to permit
interconnection of equipment. Each country has a different regulatory process.
Historically, in many developed countries, the unavailability of frequency
spectrum has inhibited the growth of wireless telecommunications networks. In
order for the Company to operate in a jurisdiction, it must obtain regulatory
approval for its systems and comply with different regulations in each
jurisdiction. Regulatory bodies worldwide are continuing the process of adopting
new standards for wireless communications products. The delays inherent in this
governmental approval process may cause the cancellation, postponement or
rescheduling of the installation of communications systems by the Company and
its customers, which in turn may have a material adverse effect on the sale of
systems by the Company to such customers. The failure to comply with current or
future regulations or changes in the interpretation of existing regulations
could result in the suspension or cessation of operations. Such regulations or
such changes in interpretation could require the Company to modify its products
and services and incur substantial costs to comply with such time-consuming
regulations and changes. In addition, the Company is also affected to the extent
that domestic and international authorities regulate the allocation and auction
of the radio frequency spectrum. Equipment to support new services can be
marketed only if permitted by suitable frequency allocations, auctions and
regulations, and the process of establishing new regulations is complex and
lengthy. To the extent PCS operators and others are delayed in deploying these
systems, the Company could experience delays in orders. Failure by the
regulatory authorities to allocate suitable frequency spectrum could have a
material adverse effect on the Company's business, financial condition and
results of operations. In addition, delays in the radio frequency spectrum
auction process in the United States could delay the Company's ability to
develop and market equipment to support new services. These delays could have a
material adverse effect on the Company's business, financial condition and
results of operations.

   The regulatory environment in which the Company operates is subject to
significant change. Regulatory changes, which are affected by political,
economic and technical factors, could significantly impact the Company's
operations by restricting development efforts by the Company and its customers,
making current systems obsolete or increasing the opportunity for additional
competition. Any such regulatory changes, including changes in the allocation of
available spectrum, could have a material adverse effect on the Company's
business, financial condition and results of operations. The Company might deem
it necessary or advisable to modify its systems and services to operate in
compliance with such regulations. Such modifications could be extremely
expensive and time-consuming.

FUTURE CAPITAL REQUIREMENTS

   The Company's future capital requirements will depend upon many factors,
including the development of new products and related software tools, potential
acquisitions, requirements to maintain adequate manufacturing facilities and
contract manufacturing agreements, the progress of the Company's research and
development efforts, expansion of the Company's marketing and sales efforts, and
the status of competitive products. There can be no assurance that additional
financing will be available to the Company on acceptable terms, or at all. As a
result of the issuance of the Notes (as defined below), the Company may be
limited in its ability to raise additional debt financing. If additional funds
are raised by issuing equity securities, further dilution to the existing
stockholders will result. If adequate funds are not available, the Company may
be required to delay, scale back or eliminate its research and development,
acquisition or manufacturing programs or obtain funds through arrangements with
partners or others that may require the Company to relinquish rights to certain
of its technologies or potential products or other assets. Accordingly, the
inability to obtain such financing could have a material adverse effect on the
Company's business, financial condition and results of operations.

UNCERTAINTY REGARDING PROTECTION OF PROPRIETARY RIGHTS

   The Company relies on a combination of patents, trademarks, trade secrets,
copyrights and a variety of other measures to protect its intellectual property
rights. The Company generally enters into confidentiality and nondisclosure
agreements with its service providers, customers and others, and attempts to
limit access to and distribution of its proprietary rights. The Company also
enters into software license agreements with its customers and others. However,
there can be no assurance that such measures will provide adequate protection
for the Company's trade secrets or other proprietary information, that disputes
with respect to the ownership of its intellectual property rights will not
arise, that the Company's trade secrets or proprietary technology will not
otherwise become known or be independently developed by competitors or that the
Company can otherwise meaningfully protect its intellectual property rights.
There can be no 

                                      34.
<PAGE>
 
assurance that any patent owned by the Company will not be invalidated,
circumvented or challenged, that the rights granted thereunder will provide
competitive advantages to the Company or that any of the Company's pending or
future patent applications will be issued with the scope of the claims sought by
the Company, if at all. Furthermore, there can be no assurance that others will
not develop similar products or software, duplicate the Company's products or
software or design around the patents owned by the Company or that third parties
will not assert intellectual property infringement claims against the Company.
In addition, there can be no assurance that foreign intellectual property laws
will adequately protect the Company's intellectual property rights abroad. The
failure of the Company to protect its proprietary rights could have a material
adverse effect on its business, financial condition and results of operations.

   Litigation may be necessary to enforce the Company's patents, copyrights and
other intellectual property rights, to protect the Company's trade secrets, to
determine the validity of and scope of the proprietary rights of others or to
defend against claims of infringement or invalidity. Such litigation could
result in substantial costs and diversion of resources and could have a material
adverse effect on the Company's business, financial condition and results of
operations. There can be no assurance that infringement, invalidity, right to
use or ownership claims by third parties or claims for indemnification resulting
from infringement claims will not be asserted in the future or that such
assertions will not materially adversely affect the Company's business,
financial condition and results of operations. If any claims or actions are
asserted against the Company, the Company may seek to obtain a license under a
third party's intellectual property rights. There can be no assurance, however,
that a license will be available under reasonable terms or at all. In addition,
should the Company decide to litigate such claims, such litigation could be
extremely expensive and time consuming and could materially adversely affect the
Company's business, financial condition and results of operations, regardless of
the outcome of the litigation.

DEPENDENCE ON KEY PERSONNEL

   The Company's future operating results depend in significant part upon the
continued contributions of its key technical and senior management personnel,
many of whom would be difficult to replace. The Company's future operating
results also depend in significant part upon its ability to attract and retain
qualified management, manufacturing, quality assurance, engineering, marketing,
sales and support personnel. Competition for such personnel is intense, and
there can be no assurance that the Company will be successful in attracting or
retaining such personnel. There may be only a limited number of persons with the
requisite skills to serve in these positions and it may be increasingly
difficult for the Company to hire such personnel over time. The loss of any key
employee, the failure of any key employee to perform in his or her current
position, the Company's inability to attract and retain skilled employees as
needed or the inability of the officers and key employees of the Company to
expand, train and manage the Company's employee base could materially adversely
affect the Company's business, financial condition and results of operations.

   The Company has experienced and may continue to experience employee turnover
due to several factors, including an expanding economy within the geographic
area in which the Company maintains its principal business offices, making it
more difficult for the Company to retain its employees. Due to this and other
factors, the Company has experienced and may continue to experience high levels
of employee turnover, which could adversely impact the Company's business,
financial condition and results of operations. The Company is presently
addressing these issues and will pursue solutions designed to retain its
employees and to provide performance incentives.

YEAR 2000 COMPLIANCE

   Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. Beginning in the year
2000, these date code fields will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, in less
than two years, computer systems and/or software used by many companies may need
to be upgraded to comply with such "Year 2000" requirements. The Company has
commenced, for all its information systems and software contained in the
products it sells, a year 2000 date conversion project to address necessary code
changes, testing and implementation. Significant uncertainty exists concerning
the potential effects associated with such compliance. The Company expects such
modifications will be made on a timely basis and does not believe that the cost
of such modifications will have a material effect on the Company's operating
results. There can be no assurance, however, that the Company and/or its vendors
will be able to modify timely and successfully such products, services and
systems to comply with year 2000 requirements, which could have a material
adverse effect on the Company's business, financial condition and results of
operations.

                                      35.

SUBSTANTIAL LEVERAGE

   In connection with the initial private placement of promissory notes due 2002
(the "Notes") in November 1997, the Company incurred $100 million of
indebtedness.  As a result, the Company's total indebtedness and stockholders'
equity, as of December 31, 1997, was approximately $101.7 million and
approximately $148.3 million, respectively. The Company's ability to make
scheduled payments of the principal of, or interest on, its indebtedness will
depend on its future performance, which is subject to economic, financial,
competitive and other factors beyond its control.

LIMITATIONS ON DIVIDENDS

   Since its incorporation in 1991, the Company has not declared or paid cash
dividends on its Common Stock, and the Company anticipates that any future
earnings will be retained for investment in its business. Any payment of cash
dividends in the future will be at the discretion of the Company's Board of
Directors and will depend upon, among other things, the Company's earnings,
financial condition, capital requirements, extent of indebtedness and
contractual restrictions with respect to the payment of dividends.

VOLATILITY OF STOCK PRICE

   The Company believes that factors such as announcements of developments
related to the Company's business, announcements of technological innovations or
new products or enhancements by the Company or its competitors, developments in
the Asia/Pacific region, sales by competitors, including sales to the Company's
customers, sales of the Company's Common Stock into the public market, including
by members of management, developments in the Company's relationships with its
customers, partners, lenders, distributors and suppliers, shortfalls or changes
in revenues, gross margins, earnings or losses or other financial results that
differ from analysts' expectations (as recently experienced upon announcement of
third quarter results), regulatory developments, fluctuations in results of
operations and general conditions in the Company's market or the markets served
by the Company's customers or the economy, could cause the price of the
Company's Common Stock to fluctuate, perhaps substantially. In recent years the
stock market in general, and the market for shares of small capitalization and
technology stocks in particular, have experienced extreme price fluctuations,
which have often been unrelated to the operating performance of affected
companies. Many companies in the telecommunications industry, including the
Company, have recently experienced historic highs in the market price of their
Common Stock. There can be no assurance that the market price of the Company's
Common Stock will not decline substantially from its historic highs, or
otherwise continue to experience significant fluctuations in the future,
including fluctuations that are unrelated to the Company's performance. Such
fluctuations could materially adversely affect the market price of the Company's
Common Stock.

GLOBAL MARKET RISKS

   Countries in the Asia/Pacific region have recently experienced weaknesses in
their currency, banking and equity markets.  These weaknesses could adversely
affect demand for the Company's products, the availability and supply of product
components to the Company and, ultimately, the Company's consolidated results of
operations.

CONTROL BY EXISTING STOCKHOLDERS; EFFECTS OF CERTAIN ANTI-TAKEOVER PROVISIONS

   Members of the Board of Directors and the executive officers of the Company,
together with members of their families and entities that may be deemed
affiliates of or related to such persons or entities, beneficially own
approximately 5% of the outstanding shares of Common Stock of the Company.
Accordingly, these stockholders are able to influence the election of the
members of the Company's Board of Directors and influence the outcome of
corporate actions requiring stockholder approval, such as mergers and
acquisitions. This level of ownership, together with the Company's stockholder
rights agreement, certificate of incorporation, equity incentive plans, bylaws
and Delaware law, may have a significant effect in delaying, deferring or
preventing a change in control of the Company and may adversely affect the
voting and other rights of other holders of Common Stock. The rights of the
holders of Common Stock will be subject to, and may be adversely affected by,
the rights of the holders of any preferred stock that may be issued in the
future. The issuance of preferred stock could have the effect of making it more
difficult for a third party to acquire a majority of the outstanding voting
stock of the Company. Although the Company has no present plans to issue shares
of preferred stock, the Board of Directors has pre-approved the terms of a
Series A Junior Participating Preferred Stock that may be issued pursuant to the
stockholder rights agreement upon the occurrence of certain triggering events.
In general, the stockholder rights agreement provides a mechanism by which the
Board of Directors and stockholders may act to substantially dilute the share
position of any takeover bidder that acquires 15% or more of the Common Stock.

                                      36.

POSSIBLE ADVERSE EFFECT ON MARKET PRICE FOR COMMON STOCK OF SHARES ELIGIBLE FOR
FUTURE SALE

   Sales of the Company's Common Stock into the market could materially
adversely affect the market price of the Company's Common Stock. Shares of
Common Stock sold in the initial public offering in March 1995 and follow-on
offerings in August 1995 and May 1996, 1,014,366 shares registered on a shelf
registration statement on Form S-3 effective in February 1998 covering shares of
Common Stock issued in the acquisitions of RT Masts and Telematics, 2,134,590
shares registered on a shelf registration statement on Form S-3 effective in
July 1997 covering shares of Common Stock issued in the acquisitions of Columbia
Spectrum Management L.P. and CRC, 140,000 shares issued in connection with the
acquisition of Atlantic Communication Sciences, Inc., and option shares
registered on the Company's registration statements covering employee
compensation plans are also, or will be in the near future, eligible for
immediate and unrestricted sale in the public market at any time. Substantially
all of the other shares of the Company's Common Stock are not restricted and are
freely tradeable in the public market.

                       REPORT OF INDEPENDENT ACCOUNTANTS

TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF P-COM, INC.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of P-COM, Inc.
and its subsidiaries at December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

THE COMPANY

     P-Com, Inc. (the "Company") was incorporated in Delaware on August 23, 1991
to engage in the design, manufacture and marketing of millimeter wave radio
systems for use in the worldwide wireless telecommunications market. The Company
also markets diagnostic, maintenance and system configuration software tools
that are complementary to its radio systems.

     On January 11, 1995, the Company effected a 1-for-3 reverse stock split. On
October 27, 1995, the Company effected a 2-for-1 forward stock split. On
September 25, 1997, the Company effected a 2-for-1 forward stock split. All
shares and per share amounts have been adjusted retroactively to reflect these
stock splits. In conjunction with an initial public offering of the Company's
Common Stock (the "Offering"), all outstanding shares of Preferred Stock were
converted into Common Stock at the closing of the Offering on March 9, 1995.

     Effective May 29, 1997, the Company acquired Control Resources Corporation
("CRC"). Effective November 28, 1997, the Company acquired RT Masts Limited ("RT
Masts") and Telematics, Inc. ("Telematics"). These transactions were accounted
for as pooling of interests and accordingly, the consolidated financial
statements for all periods presented have included the results of the combined
companies as if they had been combined since inception.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of the Company's significant accounting policies:

     Management's use of estimates and assumptions

     The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

     Principles of consolidation

     The consolidated financial statements include the accounts of the Company
and its majority-owned and wholly-owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated.

     Foreign currency translation

     The functional currency of the Company's wholly-owned and majority-owned
foreign subsidiary are the local currencies. Assets and liabilities of these
subsidiaries are translated into U.S. dollars at exchange rates in effect at the
balance sheet date. Income and expense items are translated at average exchange
rates for the period.  Accumulated net translation adjustments are recorded in
stockholders' equity. Foreign exchange transaction gains and losses are included
in the results of operations, and were not material in all periods presented.

     Fair Value of Financial Instruments

     The Company measures its financial assets and liabilities in accordance
with generally accepted accounting principles. The estimated fair value of the
Company's convertible subordinated notes was $119 million at December 31, 1997.
The estimated fair value of all other financial instruments at December 31, 1997
and 1996 was not materially different from the values presented in the
consolidated balance sheets.

     Cash and cash equivalents

     The Company considers all highly liquid debt instruments with a maturity
when acquired of three months or less to be cash equivalents.

                                      44.

     Revenue recognition

     Revenue from product sales is recognized upon shipment of the product
provided no significant obligations remain and collectibility is probable.
Provisions for estimated warranty repairs, returns and allowances are recorded
at the time products are shipped.

     Inventory

     Inventory is stated at the lower of cost or market, cost being determined
on a first-in, first-out basis.

     Property and equipment

     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method based upon the useful lives of the assets ranging from
three to seven years. Leasehold improvements are amortized using the straight-
line method based upon the shorter of the estimated useful lives or the lease
term of the respective assets.

     Software development costs

     The Company's software products are integrated into its hardware products.
Software development costs incurred prior to the establishment of technological
feasibility are expensed as incurred. Software development costs incurred
subsequent to the establishment of technological feasibility and before general
release to customers are capitalized, if material. To date, all software
development costs incurred subsequent to the establishment of technological
feasibility have been immaterial.

     Goodwill

     Goodwill, representing the excess of the purchase price over the fair value
of the net assets of the acquired entities, is being amortized on a straight-
line basis over the period of expected benefit ranging from five to twenty
years. The carrying value of goodwill will be reviewed periodically based on the
undiscounted cash flows of the entity acquired over the remaining amortization
period. Should this review indicate that goodwill will not be recoverable, the
Company's carrying value of the goodwill will be reduced to its discounted cash
flows value.

     Impairment of long-lived assets

     In the event that facts and circumstances indicate that the cost of assets
may be impaired, an evaluation of recoverability would be performed. If an
evaluation is required, the estimated future undiscounted cash flows associated
with the asset would be compared to the asset's carrying amount to determine if
a write-down to market value or discounted cash flow value is required.

     Income taxes

     The Company accounts for income taxes under the liability method, which
recognizes deferred tax assets and liabilities for the expected future tax
consequences of temporary differences between the tax bases of assets and
liabilities and their financial statement reported amounts. The measurement of
deferred tax assets is reduced, if necessary, by the amount of any tax benefits
that, based on available evidence, are not expected to be realized.

     Concentration of credit risk

     Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash and cash equivalents,
and trade accounts receivable. The Company places its cash and cash equivalents
in a variety of financial instruments such as market rate accounts and U.S.
Government agency debt securities. The Company, by policy, limits the amount of
credit exposure to any one financial institution or commercial issuer.

     To date, the Company has sold most of its products in international
markets. Sales to seven customers have been denominated in British pounds and at
December 31, 1997 and 1996 amounts due from these customers represented 30% and
47%, respectively, of accounts receivable. Any gains and/or losses incurred on
the settlement of these receivables are included in the financial statements as
they occur and have been immaterial to date.

     The Company extends credit terms to international customers of up to 120
days, which is consistent with local business practices. The Company performs 
on-going credit evaluations of its customers' financial condition and,
generally, requires no collateral from its customers.

                                     45.  
<PAGE>
 
     At December 31, 1997 and 1996, approximately 47% and 56%, respectively, of
trade accounts receivable represents amounts due from four customers. The
Company has an agreement with a bank to sell, without recourse, certain of its
trade accounts receivable. During 1997 and 1996, the Company sold $12 million
and $4 million respectively, of its trade accounts receivable.

     Off-balance sheet risk

     The Company enters into foreign forward exchange contracts to reduce the
impact of currency fluctuations of anticipated sales to British customers. The
objectives of these contracts is to neutralize the impact of foreign currency
exchange rate movements on the Company's operating results. The gains and losses
on forward exchange contracts are included in earnings when the underlying
foreign currency denominated transaction is recognized.

     The foreign exchange forward contracts described above generally require
the Company to sell foreign currencies for U.S. dollars at rates agreed to at
the inception of the contracts. The forward contracts generally have maturities
of six months or less. These contracts generally do not subject the Company to
significant market risk from exchange rate movements because the contracts are
designed to offset gains and losses on the balances and transactions being
hedged. At December 31, 1997 and 1996, the Company had forward contracts to sell
approximately $13.3 million and $25.0 million in British Pounds, respectively.
The fair value of forward exchange contracts approximates cost. The Company does
not anticipate any material adverse effect on its financial position resulting
from the use of these instruments.

     Net income per share

     The Company has adopted Statement of Financial Accounting Standards No.
128, "Earnings Per Share" ("SFAS 128"). SFAS 128 requires presentation of both
Basic EPS and Diluted EPS on the face of the income statement. Basic EPS, which
replaces primary EPS, is computed by dividing net income available to common
stockholders (numerator) by the weighted average number of common shares
outstanding (denominator) during the period. Unlike the computation of primary
EPS, Basic EPS excludes the dilutive effect of stock options. Diluted EPS
replaces fully diluted EPS and gives effect to all dilutive potential common
shares outstanding during a period. In computing Diluted EPS, the average stock
price for the period is used in determining the number of shares assumed to be
purchased from exercise of stock options rather than the higher of the average
or ending stock price as used in the computation of fully diluted EPS.

     Following is a reconciliation of the numerators and denominators of the
Basic and Diluted EPS computations for the periods presented below (in
thousands):

  Stock-based Compensation

  The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of APB No. 25, "Accounting for Stock Issued to
Employees" and complies with the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation." Under APB No. 25, compensation cost
is recognized based on the difference, if any, on the date of grant between the
fair value of the Company's stock and the consideration received.

  Recently issued accounting pronouncements

  In June 1997, the Financial Accounting Standards Board issued SFAS 130,
"Reporting Comprehensive Income". SFAS 130 establishes the standards for
reporting comprehensive income and its components in a financial statement.
Comprehensive income, as defined, includes all changes in equity (net assets)
during a period from non-owner sources. Examples of items to be included in
comprehensive income, which are excluded form net income, include foreign
currency translation adjustment and unrealized gain or loss on available for
sale securities. The disclosures prescribed by the Statement must be made
beginning with the first quarter of 1998 and requires reclassification of prior
periods for comparative purposes. The Company has not yet determined the impact,
if any, of adopting this new standard.

  In June 1997, the Financial Accounting Standards Board issued SFAS 131
"Disclosures about Segments of an Enterprise and Related Information." This
statement establishes standards for the way companies report information about
operating segments in annual financial statements. It also establishes standards
for related disclosures about products and services, geographic areas, and major
customers. The disclosures prescribed by SFAS 131 are effective in 1998. In the
initial year of adoption, interim period financial reporting is not required.
The Company has not yet determined the impact, if any, of adopting this new
standard.

NOTE 3 -- DEBT ARRANGEMENTS

  On November 5, 1997, the Company issued $100,000,000 in 4 1/4% Convertible
Subordinated Notes (The "Notes") due November 1, 2002. The Notes are convertible
at the option of the holder into shares of the Company's Common Stock at a
conversion price of $27.46 per share at any time. The Notes are redeemable by
the Company, beginning on November 5, 2000, upon 30 days notice, subject to a
declining redemption price. Interest on the Notes will be paid semi-annually on
May 1 and November 1 of each year. The Notes are subordinated to $0.8 million of
indebtedness outstanding at December 31, 1997.

                                      47.
<PAGE>
 
     The Company had a revolving line-of-credit agreement, as amended and
restated on October 31, 1997, that provided for borrowings of up to $25.0
million. Borrowings under the line were unsecured and bore interest at either a
base interest rate or a variable interest rate. The agreement required the
Company to comply with certain financial covenants including the maintenance of
specified minimum ratios. On November 10, 1997 the Company paid the outstanding
balance and terminated the line of credit.


NOTE 4 -- CAPITAL STOCK:

     Preferred Stock Under the Company's Restated Certificate of Incorporation,
the Company is authorized to issue 2,000,000 shares of Preferred Stock, par
value $0.0001 per share. The Board of Directors has the authority, without
action by the stockholders, to designate and issue preferred stock in one or
more series and to designate the dividend rate, voting rights and other rights,
preferences and restrictions of each series. In connection with the Stockholder 
Rights Agreement described below, the Board of Directors designated 750,000 of 
such shares as Series A Junior Participating Preferred Stock.

     Common Stock In March 1995, the Company received net proceeds of $26.1
million from the sale of 7,820,000 shares of Common Stock in the Offering, which
was declared effective by the Securities and Exchange Commission on March 2,1
995. In September 1995, the Company received net proceeds of $10.8 million from
the sale of 1,440,000 shares of Common Stock in a follow-on public offering. In
May 1996, the Company received net proceeds of $52.5 million from the sale of
4,196,970 shares of Common Stock in a follow-on public offering. Earnings per
share for the year ended December 31, 1996 reflects the shares issued on a
weighted average computation from the date of their issuance and therefore does
not include the full dilutive effect of these shares.

STOCKHOLDER RIGHTS AGREEMENT

     On September 26, 1997, the Board of Directors of the Company adopted a
Stockholder Rights Agreement (the "Agreement"). Pursuant to the Agreement,
rights (the "Rights") will be distributed as a dividend a the rate of one
preferred share purchase right on each outstanding share of its Common Stock
held by stockholders of record as of the close of business on November 3, 1997.
Each Right will entitle stockholders to buy one-hundredth of one share of Series
A Preferred at an exercise price of $125.00 upon certain events. The Rights will
expire ten (10) years from the date of the Agreement is executed by the Company
and BankBoston, N.A., the Rights agent.

     The Rights will be exercisable only if a person or group acquires 15% or
more of the Company's Common Stock or announces a tender offer, the consummation
of which would result in ownership by a person or group of 15% or more of the
Company's Common Stock. If, after the Rights become exercisable, P-Com is
acquired in a merger or other business combination transaction, or sells 50% or
more of its assets or earning power, each unexercised Right will entitle its
holder to purchase, at the Right's then-current exercise price, a number of the
acquiring company's common shares having a market value at the time of twice the
Right's exercise price. In addition, if a person or group acquires 15% or more
of the Company's common Stock (or cash, other securities or property, at the
discretion of the Board of Directors) having a market value of twice the Right's
exercise price. At any time within ten days after the public announcement that a
person or group has acquired beneficial ownership of 15% of more of the
Company's Common Stock, the Board, in its sole discretion, my redeem the Rights
for $0.0001 per Right.


NOTE 5 -- ACQUISITIONS:

     On February 24, 1997, the Company acquired 100% of the outstanding stock of
Technosystem S.p.A. ("Technosystem"), a Rome, Italy-based company, with
additional operations in Poland, for aggregate proceeds of $3.3 million and the
assumption of long-term debt of approximately $12.7 million in addition to other
liabilities. The Company paid $2.6 million in cash and an additional payment of
$0.7 million will be due on March 31, 1998, subject to certain indemnification
obligations of the former Technosystem security holders, as set forth in the
securities purchase agreement. Technosystem designs, manufactures and markets
equipment for transmitters and transponders for television and radio
broadcasting. The range of products include audio/video modulators, converters,
amplifiers, transponders, transmitters and microwave links.

     On March 7, 1997, the Company acquired substantially all of the assets of
Columbia Spectrum Management, L.P. ("CSM"), a Vienna, Virginia-based company,
for $7.8 million in cash and 796,612 net shares of Common Stock valued at

                                      48.
<PAGE>
 
approximately $14.5 million. CSM provides turnkey relocation services for
microwave paths over spectrum allocated by the Federal Communications Commission
for Personal Communications Services and other emerging technologies.

     The Company accounted for its acquisitions of Technosystem and CSM based on
the purchased method of accounting. The results of these acquired entities are
included from the date of acquisition and are not material to the Company's
results of operations.

     The total purchase price of the acquisitions of CSM and Technosystem was as

     The foregoing unaudited pro forma results of operations reflect one 
year's amortization of goodwill for 1996 and one quarter's amortization of 
goodwill for 1997 resulting from the acquisition of CSM and Technosystem.

     On May 29, 1997, the Company acquired all of the outstanding shares of
capital stock of CRC a provider of integrated network access devices to network
service providers, in exchange for 1,502,956 shares of P-Com Common Stock that
were issued or are issuable to former CRC security holders in a stock-for-stock
merger. CRC, located in Fair Lawn, New Jersey, manufactures products used by the
communications industry to connect end user sites to a range of communications
services. CRC's NetPath product line enables network service providers to offer
their customers a migration path from entry-level data services to cost-
effective integrated delivery of voice, video and Internet access. The NetPath
product line also supports the network service provider's introduction of new
technologies including asynchronous transfer mode and frame relay.

     On November 27, 1997, the Company acquired all of the outstanding shares of
capital stock of RT Masts, a United Kingdom-based company and Telematics, a
Virginia-based company, in exchange for 766,151 and 248,215 shares of P-Com
Common Stock, respectively. RT Masts, located in Wellingborough,
Northhamptonshire, U.K. and Telematics, located in Herndon, Virginia, supply,
install and maintain telecommunications systems and structure including antennas
covering high frequency, medium frequency and microwave systems. Both companies
manage the construction of radio system sites, construction of towers and
installation of radios and antennas at system sites.

     The Company accounted for its acquisitions of CRC, RT Masts and Telematics
as pooling of interests and, therefore, all prior period financial statements
presented have been restated to present the results of the combined companies
as if they had been combined since inception. The sales and net income (loss)
shown below combine the historical sales and net income (loss) of P-Com, CRC, RT
Masts and Telematics for the years ended December 31, 1997, 1996, and 1995.

NOTE 6 -- EMPLOYEE BENEFIT PLANS:

      At December 31, 1997, the Company had two stock-based compensation plans
which are described below. The Company has adopted the disclosure-only provision
of Statement of Financial Accounting Standards No. 123 ("SFAS 123"), "Accounting
for Stock Based Compensation". Accordingly, no compensation expense has been
recognized for its stock option plan or its stock purchase plan. Had
compensation costs for the Company's two stock-based compensation plans been
determined based on the fair value at the grant dates for awards under those
plans, consistent with the method of SFAS 123, the Company's net income and
earnings per share would have been reduced to the pro forma amounts indicated
below:

Stock Option Plans On January 11, 1995, the Company's Board of Directors adopted
the 1995 Stock Option/Stock Issuance Plan (the "1995 Plan") as a successor to
its 1992 Stock Option Plan (the "1992 Plan"). In addition to the 3,295,888
shares of Common Stock authorized for issuance under the 1992 Plan, the 1995
Plan authorizes the Board of Directors to issue an additional 640,000 shares of
Common Stock in 1995, 1,600,000 shares of Common Stock in 1996 and 3,000,000
shares of Common Stock in 1997. As of January 11, 1995, no further option grants
or stock issuances were made under the 1992 Plan, and all option grants and
stock issuances made during the remainder of 1995 were made under the 1995 Plan.
All outstanding options under the 1992 Plan were incorporated into the 1995
Plan.

                                      50.
<PAGE>
 
     Options granted under the 1992 plan are generally exercisable for a period
not to exceed ten years, and generally must be issued with exercise prices not
less than 100% and 85%, for incentive and non-qualified stock options,
respectively, of the estimated fair market value of the Common Stock on the date
of grant as determined by the Board of Directors. Options granted under the 1992
Plan are exercisable immediately upon grant. Options granted under the 1992 Plan
generally vest 25% on the first anniversary from the date of grant, and ratably
each month over the remaining thirty-six month period. Unvested shares purchased
through the exercise of stock options are subject to repurchase by the Company.

     The 1995 Plan contains three equity incentive programs: a Discretionary
Option Grant Program, a Stock Issuance Program for officers and employees of the
Company and independent consultants and advisors to the Company and an Automatic
Option Grant Program for non-employee members of the Company's Board of
Directors.

     Options under the Discretionary Option Grant Program may be granted at not
less than 85% of the fair market value per share of Common Stock on the grant
date with exercise periods not to exceed ten years. The Plan Administrator is
authorized to issue tandem stock appreciation rights and limited stock
appreciation rights in connection with the option grants.

     The Stock Issuance Program provides for the sale of Common Stock at a price
not less than 85% of fair market value. Shares may also be issued solely for
services. The administrator has discretion as to vesting provisions, including
accelerations, and may institute a loan program to assist participants with
financing stock purchases. The program also provides certain alternatives to
satisfy tax liabilities incurred by participants in connection with the program.

     Under the Automatic Option Grant Program, as amended at the May 1997 Annual
Meeting of Stockholders, participants will automatically receive an option to
purchase 40,000 shares of Common Stock upon initially joining the Board of
Directors and will receive an additional automatic grant each year at each
annual stockholders' meeting for 4,000 shares. Each option will have an exercise
price per share equal to 100% of the fair market value of the Common Stock on
the grant date. The shares subject to the initial share option and the annual
4,000 share option will vest in eight successive equal quarterly installments
upon the optionee's completion of each successive 3-month period of Board
service over the 24-month period measured from the grant date.

     The fair value of each option grant is estimated on the date of the grant
using the Black-Scholes option-pricing model with the following assumptions used
for grants in 1997, 1996 and 1995, respectively: expected volatility of 57
percent for all years; weighted average risk-free interest rates of 6.1%, 6.0%
and 6.4%, and weighted average expected lives of 3.16, 4.11 and 2.88 years.

The following table summarizes stock option activity under the Company's 1992
and 1995 Plans.

     Employee Stock Purchase Plan On January 11, 1995, the Company's Board of
Directors adopted the Employee Stock Purchase Plan (the "Purchase Plan"), which
was approved by stockholders in February 1995. The Purchase Plan permits
eligible employees to purchase Common Stock at a discount through payroll
deductions during successive offering periods with a maximum duration of 24
months. Each offering period shall be divided into consecutive semi-annual
purchase periods. The price at which the Common Stock is purchased under the
Purchase Plan is equal to 85% of the fair market value of the Common Stock on
the first day of the offering period or the last day of the purchase period,
whichever is lower. The initial offering period commenced on the effectiveness
of the Offering. A total of 900,000 shares of Common Stock has been reserved for
issuance under the Purchase Plan, as amended at the May 1997 Annual Meeting of
Stockholders. Awards and terms are established by the Company's Board of
Directors. The Purchase Plan may be canceled at any time at the discretion of
the Company's Board of Directors prior to its expiration in December 2004. Under
the Plan, the Company sold 151,874, 188,800 and 51,868 shares in 1997, 1996 and
1995, respectively.

     The fair value of the employees' purchase rights was estimated using the
Black-Scholes model with the following assumptions for 1997, 1996 and 1995,
respectively: expected volatility of 57 percent for all years; weighted-average
risk-free interest rates of 5.3%, 5.0% and 6.4%; and weighted-average expected
lives of 0.7, 0.7 and 1.2 years. The weighted-average fair value of those
purchase rights granted in 1997, 1996 and 1995 was $3.65, $1.55 and $1.10,
respectively.

                              EVENTS OF REPURCHASE
                              --------------------

     If any of the following events ("Events of Repurchase") shall occur and be
continuing:

     (a)  any representation or warranty made or deemed made or repeated by
Seller in connection with this Agreement (other than those specified in
subclause (c) below) shall prove to have been incorrect in any material respect
when made or deemed made or repeated or Seller shall fail to pay any amount
payable by it under this Agreement when due; or

     (b)  Seller shall fail to perform or observe any other material term,
covenant or agreement contained in this Agreement (other than those specified in
subclause (d) below) or its part to be performed or observed, or

     (c)  any representation or warranty made or deemed made or repeated by
Seller in connection with Sections 6(d), (h) or (i) of this Agreement shall
prove to have been incorrect in any material respect when made or deemed made or
repeated or Seller shall fail to pay any amount payable by it under this
Agreement when due; or

     (d)  Seller shall fail to perform or observe any other material term,
covenant or agreement contained in Sections 7(c), (e), (f), (h) or (i) of this
Agreement or its part to be performed or observed, or

     (e)  there is any material Dispute as to any Purchased Receivable; or

     (f)  Buyer shall not have received payment in full of any Purchased
Receivable within the time period required by the Purchased Receivable (i) from
the account debtor or (ii) if such amount is payable under any Approved
Insurance Policy, under an Approved Insurance Policy;

then, (i) in any such event listed in subclauses (a) and (b) Seller will, at the
time, in the manner and otherwise as hereinafter set forth, repurchase and pay
for the Purchased Receivables then outstanding but only at the option and upon
the demand of Buyer to the extent that Buyer has not received payment with
respect to such Purchased Receivables whether from or on behalf of the Customer
with respect thereto or under one or more Approved Insurance Policies; and (ii)
in the events listed in subclauses (c) through (f), Seller will, at the time, in
the manner and otherwise as hereinafter set forth, repurchase and pay for the
Purchased Receivable(s) to which such event relates at the option and upon the
demand of Buyer to the extent that Buyer has not received payment with respect
to such Purchased Receivable(s) whether from or on behalf of the Customer with
respect thereto or under one or more Approved Insurance Policies.
Notwithstanding any other term hereof, (A) except as provided in subclause (B)
of this sentence the aggregate amount of the payments made by Seller to Buyer as
a result of an event listed in subclause (f) shall not exceed in the aggregate
for all such events the sum of (i) five percent (5%) of the Net Invoice amount
of the Purchased Receivable(s) on the Purchase Date for such Purchased
Receivable, and (ii) five hundred thousand Dollars ($500,000) (such sum the
"Repurchase Limit"), and in any case in which such non-payment of Purchased
Receivable(s) exceeds the Repurchase Limit, then Buyer, in its sole and absolute

                                      -11-
<PAGE>
 
discretion, shall determine which particular Purchased Receivable(s) as to which
an Event of Repurchase has occurred are to be repurchased and paid for by Seller
in an amount not to exceed the Repurchase Limit; and (B) to the extent that any
insurance company that has issued an Approved Insurance Policy fails to make
payment under such Approved Insurance Policy for any reason (x) arising from (i)
any failure of the Seller to perform any of its obligations under any Approved
Insurance Policy, (ii) any material misstatement by the Seller in any
communication by the Seller to the issuer of any Approved Insurance Policy,
(iii) any other act or omission by the Seller in violation of any Approved
Insurance Policy that results in the issuer of such Approved Insurance Policy
failing to pay a claim thereunder or (iv) any exclusion under an Approved
Insurance Policy that results from any event or action caused or under the
control of Seller, and (y) such item in subclauses (i), (ii), (iii) or (iv)
above constitutes a breach by Seller of any representation, warranty or covenant
under this Agreement, then the Repurchase Limit shall not apply and the Buyer
may require the Seller to repurchase each of the Purchased Receivables for which
payment under an Approved Insurance Policy was not made for the reasons stated
above.  Such purchase shall be made at the time specified by Buyer at a
repurchase price equal to the unpaid aggregate principal amount then outstanding
plus unpaid interest and any other amount payable in accordance with the terms
of such Purchased Receivables accrued to the date of repurchase or with the
terms of this Agreement.  The repurchase price of the Purchased Receivables
repurchased by Seller pursuant to this article shall be paid in immediately
available funds without recourse to or warranty by Buyer. Upon any such
repurchase, the Buyer shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as shall be necessary to vest in the
Seller title to any Purchased Receivable that is repurchased hereunder.
Notwithstanding any other term hereof, in the case of the occurrence of an event
listed in subclause (f), and to the extent that an insurance company that has
issued an Approved Insurance Policy is declared bankrupt or insolvent and does
not pay a claim as the result thereof, then Seller shall have no obligation to
repurchase and pay for the Purchased Receivables to the extent such insurance
company is obligated to pay such amount under such Approved Insurance Policy but
has not done so as a result of its bankruptcy or insolvency.

Mr. George Roberts
P-COM, Inc.
3175 S. Winchester Blvd.
Campbell, CA  95008

Dear George:


     We are pleased to inform you that the Board of Directors of P-Com, Inc.
(the "Company") has recently authorized and approved a special benefit program
for you and the other key executives.  The purpose of this letter agreement is
to set forth the terms and conditions of your benefit package and to explain the
limitations which will govern the overall value of your benefits.

     Your benefits will become payable in the event your employment terminates,
either voluntarily or involuntarily for any reason, within twenty-four (24)
months following certain changes in ownership or control of the Company.  To
understand the full scope of your benefits, you should familiarize yourself with
the definitional provisions of Section I of this letter agreement.  The benefits
comprising your package are detailed in Section II.  Section III addresses the
treatment of any excise tax imposed in the event that any of your benefits
constitute excess parachute payments for purposes of the Federal tax laws and
Section IV deals with ancillary matters affecting your arrangement.

                            SECTION I - DEFINITIONS

     For purposes of this letter agreement the following definitions will be in
effect:

     1.1  AVERAGE COMPENSATION means the average of your W-2 wages from the
Company for the five (5) calendar years completed immediately prior to the
calendar year in which the Change of Control is effected.  Any W-2 wages for a
partial year of employment will be annualized, in accordance with the frequency
which such wages are paid during such partial year, before inclusion in your
Average Compensation.  If any of your compensation from the Company during such
five (5)-year or shorter period was not included in your W-2 wages for U.S.
income tax purposes, either because you were not a U.S. citizen or resident or
because such compensation was excludible from income as foreign earned income
under Code Section 911 or

as pre-tax income under Code Section 125 or 402(g), then such compensation will
nevertheless be included in your Average Compensation to the same extent as if
it were part of your W-2 wages.

     1.2  BASE SALARY means the annual rate of base salary in effect for you
immediately prior to the Change in Control or (if greater) the annual rate of
base salary in effect at the time of your Termination.

change in ownership or control of the Company:

          (i) a merger or consolidation in which the Company is not the
     surviving entity, except for a transaction the principal purpose of which
     is to change the State in which the Company is incorporated,

          (ii) the sale, transfer or other disposition of all or substantially
     all of the assets of the Company in complete liquidation or dissolution
     of the Company,

          (iii) any reverse merger in which the Company is the surviving
     entity but in which securities possessing fifty percent (50%) or more of
     the total combined voting power of the Company's outstanding securities
     are transferred to person or persons different from the persons holding
     those securities immediately prior to such merger,

           (iv)  a Hostile Take-Over, or

           (v) the acquisition, directly or indirectly by any person or
     related group of persons (other than the Company or a person that

     control with, the Company), of beneficial ownership (within the meaning
     of Rule 13d-3 of the 1934 Act) of securities possessing more than thirty
     percent (30%) of the total combined voting power of the Company's
     outstanding securities pursuant to a tender or exchange offer made
     directly to the Company's stockholders.

     been elected or nominated for election as Board members during such period
     by at least a two-thirds majority of the Board members described in clause
     (I) who were still in office at the time such election or nomination was
     approved by the Board.

           -------------------------------                            
     installment thereof) which automatically accelerates, pursuant to the
     acceleration provisions of the agreement evidencing that Option, upon a
     change in control or ownership of the Company under certain specified
     circumstances.

           Severance-Accelerated Options: any outstanding Option (or

     installment thereof) which accelerates upon your Termination pursuant to

Accelerated Option or any Severance-Accelerated Option, the portion of that

with the valuation provisions established under Code Section 280G and the
applicable Treasury Regulations and will include an appropriate dollar
adjustment to reflect the lapse of your obligation to remain in the Company's
employ as a condition to the vesting of the accelerated installment. In no

<PAGE>

      1.15 OTHER PARACHUTE PAYMENT means any payment in the nature of
compensation (other than the benefits to which you become entitled under Section
II of this letter agreement) which are made to you in connection with the Change
in Control and which accordingly qualify as parachute payments within the
meaning of Code Section 280G(b)(2) and the Treasury Regulations issued
thereunder.  Your Other Parachute Payments will include (without limitation) the
Present Value, measured as of the Change in Control, of the aggregate Option
Parachute Payment attributable to your Acquisition-Accelerated Options (if any).

      1.16  PLANS means (i) the Company's 1992 Stock Option Plan, (ii)
the Company's 1995 Stock Option/Stock Issuance Plan, as amended or restated from

become entitled in connection with the Change in Control or the subsequent
Termination of your employment, including (without limitation) the Option
Parachute Payment attributable to your Severance-Acceleration Options, your
Severance Payments under Section II of this letter agreement and the Option
Parachute Payment attributable to your Acquisition-Accelerated Options.  The
Present Value of each such payment will be determined in accordance with the
provisions of Code Section 280G(d)(4), utilizing a discount rate equal to one
hundred twenty percent (120%) of the applicable Federal rate in effect at the
time of such determination, compounded semi-annually to the effective date of
the Change in Control.

covenants set forth in Paragraph 2.4.

          Should your Termination occur in connection with a Hostile Take-Over,
the Severance Payments will be made to you in a lump sum payment within thirty
(30) days after your Termination and the provisions of Paragraph 2.4 will not

shares of Common Stock at the time subject to that Option.  Each such
accelerated Option, together with all your other vested Options, will
<PAGE>
 
                                                                          Page 7

Option.

          2.3  ADDITIONAL BENEFITS
               -------------------

shall also be entitled to all health care coverage as approved by the Company's
Compensation Committee on July 17, 1997.  The coverage so provided you and your

          You will receive an immediate lump sum payment of all unpaid vacation

          2.4  RESTRICTIVE COVENANTS
               ---------------------

          For the twenty-four (24)-month period following your Termination, you
will not:

               (i) directly or indirectly, whether for your own account or as an
     employee, director, consultant or advisor, provide services to any business
     enterprise which is at the time in competition with any of the Company's
     then-existing or formally planned product lines and which is located
     geographically in an area where the Company maintains substantial business
     activities;

               (ii) directly or indirectly encourage or solicit any individual
     to leave the Company's employ for any reason or interfere in any other
     manner with the employment relationships at the time existing between the
     Company and its current or prospective employees; or

               (iii)  induce or attempt to induce any customer, supplier,
     distributor, licensee or other business affiliate of the Company to cease
     doing
<PAGE>
 
                                                                          Page 8


     business with the Company or in any way interfere with the existing
     business relationship between any such customer, supplier, distributor,
     licensee or other business affiliate and the Company.

          You acknowledge that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason of
your breach of the foregoing restrictive covenants.  Accordingly, in the event
of any such breach, the Company will, in addition to the cessation of the
severance benefits provided under this agreement and any remedies available to
the Company at law, be entitled to obtain equitable relief in the form of an
injunction precluding you from continuing to engage in such breach.

          None of the foregoing restrictive covenants will be applicable in the
event your Termination occurs in connection with a Hostile Take-Over.

                        SECTION III - PARACHUTE PAYMENTS

          3.1   PARACHUTE TAX GROSS-UP
                ----------------------

          Should the aggregate Present Value (measured as of the Change in
Control) of (i) the benefits to which you become entitled under Section II at
the time of your Termination (namely the Severance Payments, the Option
Parachute Payment attributable to your Severance-Accelerated Options and your
Health Care Continuation) and (ii) all Other Parachute Payments to which you are
entitled, exceed 2.99 times your Actual Average Compensation (the "Parachute
Limit") and thereby result in an excise tax liability under Section 4999 of the
Code, then the Company will provide you with a full tax gross-up with respect to
such excise tax liability.  The amount of such tax gross-up will be determined
pursuant to the following formula:

               X  =  Y /  1 - (A + B + C), where

               X is the total dollar payment (the "Tax Gross-Up") required to be
               paid under this letter agreement,

               Y is the total excise tax (the "Parachute Tax") imposed on you
               pursuant to Section 4999 of the Code (or any successor provision)
               with respect to the Severance Payments, the Option Parachute
               Payment attributable to your Severance-Accelerated Options, your
               Health Care Continuation and all Other Parachute Payments,

               A is the excise tax rate in effect under Section 4999 of the Code
               for excess parachute payments,
<PAGE>
 
                                                                          Page 9

               B is the highest combined marginal federal income and
               applicable state income tax rate in effect for you, after
               taking into account the deductibility of state income taxes
               against federal income taxes to the extent allowable, for the
               calendar year in which the Tax Gross-Up is paid, and

               C is the applicable Hospital Insurance (Medicare) Tax Rate in
               effect for you for the calendar year in which the Tax Gross-Up is
               paid.

          3.2  INITIAL PAYMENT
               ---------------

          Within ninety (90) days after each determination is made by the
Internal Revenue Service or your tax advisor that you have received a parachute
payment for which you are liable for a Parachute Tax, you will identify the
nature of such parachute payment to the Company and submit to the Company the
calculation of the Parachute Tax attributable to that payment and the Tax Gross-
Up to which you are entitled with respect to such tax liability.  The Company
will pay such Tax Gross-Up to you (net of all applicable withholding taxes,
including any taxes required to be withheld under Section 4999 of the Code)
within ten (10) business days after your submission of the calculation of such
Parachute Tax and the resulting Tax Gross-Up, provided such calculations
represent a reasonable interpretation of the applicable law and regulations.

          3.3  FINAL DETERMINATION
               -------------------

          In the event that your actual Parachute Tax liability is determined by
a Final Determination to be greater than the Parachute Tax liability taken into
account for purposes of the Tax-Gross-Up paid pursuant to this Section, then
within ninety (90) days following the Final Determination, you will submit to
the Company a new Parachute Tax calculation based upon the Final Determination.
Within ten (10) business days after receipt of such calculation, the Company
will pay you the additional Tax Gross-Up attributable to such excess Parachute
Tax liability.

          3.4  REFUND
               ------

          In the event that your actual Parachute Tax liability is determined by
a Final Determination to be less than the Parachute Tax liability taken into
account for purposes of the Tax Gross-Up paid to you pursuant to this Section,
then you will refund to the Company, promptly upon receipt, any federal or state
tax refund attributable to the Parachute Tax overpayment.

          3.5  DEFINITION
               ----------

          For purposes of this section, a Final Determination means an audit
adjustment by the Internal Revenue Service that is either agreed to by you or
your estate or an adjustment that is sustained by a court of competent
jurisdiction in a decision with which you concur or with respect to which the
period within which an appeal may be filed has lapsed without a notice of appeal
being filed.

                     SECTION IV - MISCELLANEOUS PROVISIONS

          4.1  DEATH
               -----

          In the event of your death, the Severance Payments (including the
Parachute Payments) to which you become entitled under this letter agreement
will be made, on the due date hereunder, to the executors or administrators of
your estate.  Should you die before you exercise all your outstanding Options,
then such Options may be exercised, within twelve (12) months after your death,
by the executors or administrators of your estate or by persons to whom the
Options are transferred pursuant to your will or in accordance with the laws of
inheritance. In no event, however, may any such Option be exercised after the
specified expiration date of the option term.

          4.2  GENERAL CREDITOR STATUS
               -----------------------

          The payments and benefits to which you become entitled hereunder will
be paid, when due, from the general assets of the Company, and no trust fund,
escrow arrangement or other segregated account will be established as a funding
vehicle for such payment.  Accordingly, your right (or the right of the personal
representatives or beneficiaries of your estate) to receive any payments or
benefits hereunder will at all times be that of a general creditor of the
Company and will have no priority over the claims of other general creditors.

          4.3  INDEMNIFICATION
               ---------------

          The indemnification provisions for officers and directors under the
Company certificate of incorporation, indemnification agreement, Bylaws and
insurance policies will (to the maximum extent permitted by law) be extended to
you with respect to any and all matters, events or transactions occurring or
effected during your employment with the Company.

          4.4  MISCELLANEOUS
               -------------

          This letter agreement will be binding upon the Company, its successors
and assigns (including, without limitation, the surviving entity in any Change
in Control) and is to be construed and interpreted under the laws of the State
of California.  Except as set forth herein, this letter agreement supersedes all
prior agreements between you and the Company relating to the subject of
severance benefits payable upon a change in control or ownership of the Company,
including the Plans and the agreements evidencing the Options, and may only be
amended by written instrument signed by you and an authorized officer of the
Company.  If any provision of this letter agreement as applied to any party or
to any circumstance should be adjudged by a court of competent jurisdiction to
be void or unenforceable for any reason, the invalidity of that provision will
in no way affect (to the maximum extent permissible by law) the application of
such provision under circumstances different from those adjudicated by the
court, the application of any other provision of this letter agreement, or the
enforceability or invalidity of this letter agreement as a whole.  Should any
provision of this letter agreement become or be deemed invalid, illegal or
unenforceable in any jurisdiction by reason of the scope, extent or duration of
its coverage, then such provision will be deemed amended to the extent necessary
to conform to applicable law so as to be valid and enforceable or, if such
provision cannot be so amended without materially altering the intention of the
parties, then such provision will be stricken and the remainder of this letter
agreement will continue in full force and effect.

          4.5  ATTORNEY FEES
               -------------

          In the event legal proceeding should be initiated by you or by the
Company with respect to any controversy, claim or dispute relating to the
interpretation or application of the provisions of this letter agreement or any
benefits payable hereunder, the prevailing party in such proceedings will be
entitled to recover from the losing party reasonable attorney fees and costs
incurred in connection with such proceedings or in the enforcement or collection
of any judgment or award rendered in such proceedings.  For purposes of this
provision, the prevailing party means the party determined by the court to have
most nearly prevailed in the proceedings, even if that party does not prevail in
all matters, and does not necessarily mean the party in whose favor the judgment
is actually rendered.  If the Company materially breaches any of its obligations
under this letter agreement and fails to cure that breach within thirty (30)
days after written notice from you, you will then be entitled to reimbursement
from the Company for any reasonable expenses and attorney fees you incur in
having the Company subsequently cure that breach, whether or not legal
proceedings are actually commenced in connection with such breach.

Mr. Michael Sophie
P-COM, Inc.
3175 S. Winchester Blvd.
Campbell, CA  95008

Dear Mike:


     We are pleased to inform you that the Board of Directors of P-Com, Inc.
(the "Company") has recently authorized and approved a special benefit program
for you and the other key executives.  The purpose of this letter agreement is
to set forth the terms and conditions of your benefit package and to explain the
limitations which will govern the overall value of your benefits.

     Your benefits will become payable in the event your employment terminates,
either voluntarily or involuntarily for any reason, within twenty-four (24)
months following certain changes in ownership or control of the Company.  To
understand the full scope of your benefits, you should familiarize yourself with
the definitional provisions of Section I of this letter agreement.  The benefits
comprising your package are detailed in Section II.  Section III addresses the
treatment of any excise tax imposed in the event that any of your benefits
constitute excess parachute payments for purposes of the Federal tax laws and
Section IV deals with ancillary matters affecting your arrangement.

                            SECTION I - DEFINITIONS

     For purposes of this letter agreement the following definitions will be in
effect:

     1.1  AVERAGE COMPENSATION means the average of your W-2 wages from the
Company for the five (5) calendar years completed immediately prior to the
calendar year in which the Change of Control is effected.  Any W-2 wages for a
partial year of employment will be annualized, in accordance with the frequency
which such wages are paid during such partial year, before inclusion in your
Average Compensation.  If any of your compensation from the Company during such
five (5)-year or shorter period was not included in your W-2 wages for U.S.
income tax purposes, either because you were not a U.S. citizen or resident or
because such compensation was excludible from income as foreign earned income
under Code Section 911 or
<PAGE>
 
                                                                          Page 2

as pre-tax income under Code Section 125 or 402(g), then such compensation will
nevertheless be included in your Average Compensation to the same extent as if
it were part of your W-2 wages.

     1.2  BASE SALARY means the annual rate of base salary in effect for you
immediately prior to the Change in Control or (if greater) the annual rate of
base salary in effect at the time of your Termination.

     1.4  CHANGE IN CONTROL means any of the following transactions effecting a
change in ownership or control of the Company:

     surviving entity, except for a transaction the principal purpose of which
     is to change the State in which the Company is incorporated,

               (ii) the sale, transfer or other disposition of all or
     substantially all of the assets of the Company in complete liquidation or
     dissolution of the Company,

               (iii)  any reverse merger in which the Company is the surviving
     entity but in which securities possessing fifty percent (50%) or more of
     the total combined voting power of the Company's outstanding securities are
     transferred to person or persons different from the persons holding those
     securities immediately prior to such merger,

               (iv)  a Hostile Take-Over, or

               (v) the acquisition, directly or indirectly by any person or
     related group of persons (other than the Company or a person that directly

     the Company), of beneficial ownership (within the meaning of Rule 13d-3 of
     the 1934 Act) of securities possessing more than thirty percent (30%) of
     the total combined voting power of the Company's outstanding securities
     pursuant to a tender or exchange offer made directly to the Company's

     securities possessing more than twenty-five percent (25%) of the total
     combined voting power of the Company's outstanding securities pursuant to a
     transaction or series of related transactions which the Board does not at
     any time recommend the Company's stockholders to accept or approve, or

               (ii) a change in the composition of the Board over a period of
     twenty-four (24) consecutive months or less such that a majority of the
     Board ceases, by reason of one or more contested elections for Board
     membership, to be comprised of individuals who either (I) have been members
     of the Board continuously since the beginning of such period or (II) have
     been elected or nominated for election as Board members during such period
     by at least a two-thirds majority of the Board members described in clause
     (I) who were still in office at the time such election or nomination was
     approved by the Board.

     performance plan) or (III) a change in your place of employment which is

     effected without your written concurrence, or

          1.12 1934 ACT shall mean the Securities Exchange Act of 1934, as
amended.

          1.13 OPTION means any option granted to you under the Plans which
is outstanding at the time of the Change in Control or your subsequent
Termination.  Your Options will be divided into two (2) separate categories as

               -------------------------------                            
     installment thereof) which automatically accelerates, pursuant to the
     acceleration provisions of the agreement evidencing that Option, upon a
     change in control or ownership of the Company under certain specified
     circumstances.

               Severance-Accelerated Options: any outstanding Option (or
               -----------------------------

Acquisition-Accelerated Option or any Severance-Accelerated Option, the portion
of that Option deemed to be a parachute payment under Code Section 280G and the
Treasury Regulations issued thereunder.  The portion of such Option which is
categorized as an Option Parachute Payment will be calculated in accordance with
the valuation provisions established under Code Section 280G and the applicable
Treasury Regulations and will include an appropriate dollar adjustment to
reflect the lapse of your obligation to remain in the Company's employ as a
condition to the vesting of the accelerated installment.  In no event, however,
will the Option Parachute Payment attributable to any Acquisition-Accelerated
Option or Severance-Accelerated Option (or
<PAGE>
 
                                                                          Page 5

those shares) existing at the time of acceleration.

          1.15 OTHER PARACHUTE PAYMENT means any payment in the nature of
compensation (other than the benefits to which you become entitled under Section
II of this letter agreement) which are made to you in connection with the Change
in Control and which accordingly qualify as parachute payments within the
meaning of Code Section 280G(b)(2) and the Treasury Regulations issued
thereunder.  Your Other Parachute Payments will include (without limitation) the
Present Value, measured as of the Change in Control, of the aggregate Option
Parachute Payment attributable to your Acquisition-Accelerated Options (if any).

          1.16 PLANS means (i) the Company's 1992 Stock Option Plan, (ii)

Change in Control, of any payment in the nature of compensation to which you
become entitled in connection with the Change in Control or the subsequent
Termination of your employment, including (without limitation) the Option
Parachute Payment attributable to your Severance-Acceleration Options, your
Severance Payments under Section II of this letter agreement and the Option
Parachute Payment attributable to your Acquisition-Accelerated Options. The
Present Value of each such payment will be determined in accordance with the
provisions of Code Section 280G(d)(4), utilizing a discount rate equal to one
hundred twenty percent (120%) of the applicable Federal rate in effect at the
time of such determination, compounded semi-annually to the effective date of
the Change in Control.

          1.18 SEVERANCE PAYMENTS means the severance payments to which you may
become entitled under Section II in the event of a Termination following a
Change in Control, subject, however, to the dollar limitations of Section III.

                             SECTION II - BENEFITS

Control occurs.

          (C)  PAYMENT OF SEVERANCE PAYMENTS

          In the absence of a Hostile Take-Over, your Severance Payments will be
made at bi-weekly intervals following your Termination.  However, these payments
will immediately terminate in the event you fail to abide by the restrictive
covenants set forth in Paragraph 2.4.

          Should your Termination occur in connection with a Hostile Take-Over,
the Severance Payments will be made to you in a lump sum payment within thirty
(30) days after your Termination and the provisions of Paragraph 2.4 will not

otherwise fully exercisable) automatically accelerate so that each such Option
will become fully vested and immediately exercisable for the total number of
shares of Common Stock at the time subject to that Option.  Each such
accelerated Option, together with all your other vested Options, will
<PAGE>
 
                                                                          Page 7


remain exercisable for fully-vested shares until the earlier of (i) the

years measured from the date of your Termination or greater if set forth in the
Option.

          2.3  ADDITIONAL BENEFITS
               -------------------

          (A)  HEALTH CARE COVERAGE

after the date of your Termination or (ii) the first date that you are covered
under another employer's health benefit program which provides substantially the
same level of benefits without exclusion for pre-existing medical conditions.

          2.4  RESTRICTIVE COVENANTS
               ---------------------

          For the twenty-four (24)-month period following your Termination, you
will not:

               (i) directly or indirectly, whether for your own account or as an
     employee, director, consultant or advisor, provide services to any business
     enterprise which is at the time in competition with any of the Company's
     then-existing or formally planned product lines and which is located
     geographically in an area where the Company maintains substantial business
     activities;

               (ii) directly or indirectly encourage or solicit any individual
     to leave the Company's employ for any reason or interfere in any other
     manner with the employment relationships at the time existing between the
     Company and its current or prospective employees; or

               (iii)  induce or attempt to induce any customer, supplier,
     distributor, licensee or other business affiliate of the Company to cease
     doing
<PAGE>
 
                                                                          Page 8


     business with the Company or in any way interfere with the existing
     business relationship between any such customer, supplier, distributor,
     licensee or other business affiliate and the Company.

          You acknowledge that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason of
your breach of the foregoing restrictive covenants.  Accordingly, in the event
of any such breach, the Company will, in addition to the cessation of the
severance benefits provided under this agreement and any remedies available to
the Company at law, be entitled to obtain equitable relief in the form of an
injunction precluding you from continuing to engage in such breach.

          None of the foregoing restrictive covenants will be applicable in the
event your Termination occurs in connection with a Hostile Take-Over.

                        SECTION III - PARACHUTE PAYMENTS

          3.1      PARACHUTE TAX GROSS-UP
                   ----------------------

          Should the aggregate Present Value (measured as of the Change in
Control) of (i) the benefits to which you become entitled under Section II at
the time of your Termination (namely the Severance Payments, the Option
Parachute Payment attributable to your Severance-Accelerated Options and your
Health Care Continuation) and (ii) all Other Parachute Payments to which you are
entitled, exceed 2.99 times your Actual Average Compensation (the "Parachute
Limit") and thereby result in an excise tax liability under Section 4999 of the
Code, then the Company will provide you with a full tax gross-up with respect to
such excise tax liability.  The amount of such tax gross-up will be determined
pursuant to the following formula:

               X  =  Y /  1 - (A + B + C), where

               X is the total dollar payment (the "Tax Gross-Up") required to be
               paid under this letter agreement,

               Y is the total excise tax (the "Parachute Tax") imposed on you
               pursuant to Section 4999 of the Code (or any successor provision)
               with respect to the Severance Payments, the Option Parachute
               Payment attributable to your Severance-Accelerated Options, your
               Health Care Continuation and all Other Parachute Payments,

               A is the excise tax rate in effect under Section 4999 of the Code
               for excess parachute payments,

               B is the highest combined marginal federal income and applicable
               state income tax rate in effect for you, after taking into
               account the deductibility of state income taxes against federal
               income taxes to the extent allowable, for the calendar year in
               which the Tax Gross-Up is paid, and

               C is the applicable Hospital Insurance (Medicare) Tax Rate in
               effect for you for the calendar year in which the Tax Gross-Up is
               paid.

          3.2      INITIAL PAYMENT
                   ---------------

          Within ninety (90) days after each determination is made by the
Internal Revenue Service or your tax advisor that you have received a parachute
payment for which you are liable for a Parachute Tax, you will identify the
nature of such parachute payment to the Company and submit to the Company the
calculation of the Parachute Tax attributable to that payment and the Tax Gross-
Up to which you are entitled with respect to such tax liability.  The Company
will pay such Tax Gross-Up to you (net of all applicable withholding taxes,
including any taxes required to be withheld under Section 4999 of the Code)
within ten (10) business days after your submission of the calculation of such
Parachute Tax and the resulting Tax Gross-Up, provided such calculations
represent a reasonable interpretation of the applicable law and regulations.

          3.3      FINAL DETERMINATION
                   -------------------

          In the event that your actual Parachute Tax liability is determined by
a Final Determination to be greater than the Parachute Tax liability taken into
account for purposes of the Tax-Gross-Up paid pursuant to this Section, then
within ninety (90) days following the Final Determination, you will submit to
the Company a new Parachute Tax calculation based upon the Final Determination.
Within ten (10) business days after receipt of such calculation, the Company
will pay you the additional Tax Gross-Up attributable to such excess Parachute
Tax liability.

          3.4      REFUND
                   ------

          In the event that your actual Parachute Tax liability is determined by
a Final Determination to be less than the Parachute Tax liability taken into
account for purposes of the Tax Gross-Up paid to you pursuant to this Section,
then you will refund to the Company, promptly upon receipt, any federal or state
tax refund attributable to the Parachute Tax overpayment.

          3.5  DEFINITION
               ----------

          For purposes of this section, a Final Determination means an audit
adjustment by the Internal Revenue Service that is either agreed to by you or
your estate or an adjustment that is sustained by a court of competent
jurisdiction in a decision with which you concur or with respect to which the
period within which an appeal may be filed has lapsed without a notice of appeal
being filed.

                     SECTION IV - MISCELLANEOUS PROVISIONS

          4.1      DEATH
                   -----

          In the event of your death, the Severance Payments (including the
Parachute Payments) to which you become entitled under this letter agreement
will be made, on the due date hereunder, to the executors or administrators of
your estate.  Should you die before you exercise all your outstanding Options,
then such Options may be exercised, within twelve (12) months after your death,
by the executors or administrators of your estate or by persons to whom the
Options are transferred pursuant to your will or in accordance with the laws of
inheritance. In no event, however, may any such Option be exercised after the
specified expiration date of the option term.

          4.2      GENERAL CREDITOR STATUS
                   -----------------------

          The payments and benefits to which you become entitled hereunder will
be paid, when due, from the general assets of the Company, and no trust fund,
escrow arrangement or other segregated account will be established as a funding
vehicle for such payment.  Accordingly, your right (or the right of the personal
representatives or beneficiaries of your estate) to receive any payments or
benefits hereunder will at all times be that of a general creditor of the
Company and will have no priority over the claims of other general creditors.

          4.3      INDEMNIFICATION
                   ---------------

          The indemnification provisions for officers and directors under the
Company certificate of incorporation, indemnification agreement, Bylaws and
insurance policies will (to the maximum extent permitted by law) be extended to
you with respect to any and all matters, events or transactions occurring or
effected during your employment with the Company.

          4.4  MISCELLANEOUS
               -------------

          This letter agreement will be binding upon the Company, its successors
and assigns (including, without limitation, the surviving entity in any Change
in Control) and is to be construed and interpreted under the laws of the State
of California.  Except as set forth herein, this letter agreement supersedes all
prior agreements between you and the Company relating to the subject of
severance benefits payable upon a change in control or ownership of the Company,
including the Plans and the agreements evidencing the Options, and may only be
amended by written instrument signed by you and an authorized officer of the
Company.  If any provision of this letter agreement as applied to any party or
to any circumstance should be adjudged by a court of competent jurisdiction to
be void or unenforceable for any reason, the invalidity of that provision will
in no way affect (to the maximum extent permissible by law) the application of
such provision under circumstances different from those adjudicated by the
court, the application of any other provision of this letter agreement, or the
enforceability or invalidity of this letter agreement as a whole.  Should any
provision of this letter agreement become or be deemed invalid, illegal or
unenforceable in any jurisdiction by reason of the scope, extent or duration of
its coverage, then such provision will be deemed amended to the extent necessary
to conform to applicable law so as to be valid and enforceable or, if such
provision cannot be so amended without materially altering the intention of the
parties, then such provision will be stricken and the remainder of this letter
agreement will continue in full force and effect.

          4.5  ATTORNEY FEES
               -------------

          In the event legal proceeding should be initiated by you or by the
Company with respect to any controversy, claim or dispute relating to the
interpretation or application of the provisions of this letter agreement or any
benefits payable hereunder, the prevailing party in such proceedings will be
entitled to recover from the losing party reasonable attorney fees and costs
incurred in connection with such proceedings or in the enforcement or collection
of any judgment or award rendered in such proceedings.  For purposes of this
provision, the prevailing party means the party determined by the court to have
most nearly prevailed in the proceedings, even if that party does not prevail in
all matters, and does not necessarily mean the party in whose favor the judgment
is actually rendered.  If the Company materially breaches any of its obligations
under this letter agreement and fails to cure that breach within thirty (30)
days after written notice from you, you will then be entitled to reimbursement
from the Company for any reasonable expenses and attorney fees you incur in
having the Company subsequently cure that breach, whether or not legal
proceedings are actually commenced in connection with such breach.

Mr. Pier Antoniucci
P-COM, Inc.
3175 S. Winchester Blvd.
Campbell, CA  95008

Dear Pier:


     We are pleased to inform you that the Board of Directors of P-Com, Inc.
(the "Company") has recently authorized and approved a special benefit program
for you and the other key executives.  The purpose of this letter agreement is
to set forth the terms and conditions of your benefit package and to explain the
limitations which will govern the overall value of your benefits.

     Your benefits will become payable in the event your employment terminates,
either voluntarily or involuntarily for any reason, within twenty-four (24)
months following certain changes in ownership or control of the Company.  To
understand the full scope of your benefits, you should familiarize yourself with
the definitional provisions of Section I of this letter agreement.  The benefits
comprising your package are detailed in Section II.  Section III addresses the
treatment of any excise tax imposed in the event that any of your benefits
constitute excess parachute payments for purposes of the Federal tax laws and
Section IV deals with ancillary matters affecting your arrangement.

                            SECTION I - DEFINITIONS

     For purposes of this letter agreement the following definitions will be in
effect:

     1.1  AVERAGE COMPENSATION means the average of your W-2 wages from the
Company for the five (5) calendar years completed immediately prior to the
calendar year in which the Change of Control is effected.  Any W-2 wages for a
partial year of employment will be annualized, in accordance with the frequency
which such wages are paid during such partial year, before inclusion in your
Average Compensation.  If any of your compensation from the Company during such
five (5)-year or shorter period was not included in your W-2 wages for U.S.
income tax purposes, either because you were not a U.S. citizen or resident or
because such compensation was excludible from income as foreign earned income
under Code Section 911 or
<PAGE>
 
as pre-tax income under Code Section 125 or 402(g), then such compensation will
nevertheless be included in your Average Compensation to the same extent as if
it were part of your W-2 wages.

     1.2  BASE SALARY means the annual rate of base salary in effect for you
immediately prior to the Change in Control or (if greater) the annual rate of
base salary in effect at the time of your Termination.

     1.3  BOARD means the Company's Board of Directors.

     1.4  CHANGE IN CONTROL means any of the following transactions effecting a
change in ownership or control of the Company:

               (i) a merger or consolidation in which the Company is not the
     surviving entity, except for a transaction the principal purpose of which
     is to change the State in which the Company is incorporated,

               (ii) the sale, transfer or other disposition of all or
     substantially all of the assets of the Company in complete liquidation or
     dissolution of the Company,

               (iii)  any reverse merger in which the Company is the surviving
     entity but in which securities possessing fifty percent (50%) or more of
     the total combined voting power of the Company's outstanding securities are
     transferred to person or persons different from the persons holding those
     securities immediately prior to such merger,

               (iv)  a Hostile Take-Over, or

               (v) the acquisition, directly or indirectly by any person or
     related group of persons (other than the Company or a person that directly
     or indirectly controls, is controlled by, or is under common control with,
     the Company), of beneficial ownership (within the meaning of Rule 13d-3 of
     the 1934 Act) of securities possessing more than thirty percent (30%) of
     the total combined voting power of the Company's outstanding securities
     pursuant to a tender or exchange offer made directly to the Company's
     stockholders.

Stock subject to any of your Options, the closing selling price per share of
Common Stock on the date in question, as reported on the Nasdaq National Market.
If there is no reported sale of Common Stock on such date, then the closing
selling price on the Nasdaq National Market on the next preceding day for which
there does exist such quotation shall be determinative of Fair Market Value.

          1.9  HEALTH CARE COVERAGE means the continued health care coverage
to which you and your eligible dependents may become entitled under Section II
of this letter agreement upon the Termination of your employment.

          1.10 HOSTILE TAKE-OVER means either of the following

               (i) the successful acquisition by a person or a group of related

     securities possessing more than twenty-five percent (25%) of the total

     of the Board continuously since the beginning of such period or (II) have
     been elected or nominated for election as Board members during such period
     by at least a two-thirds majority of the Board members described in clause
     (I) who were still in office at the time such election or nomination was
     approved by the Board.

          1.11 INVOLUNTARY TERMINATION means the termination of your employment
with the Company (or successor):

               (i) involuntarily upon your discharge or dismissal,

               (ii) voluntarily upon your resignation following (I) a change in
     your position with the Company (or successor) which reduces your duties or
     level of responsibility or otherwise changes the level of management to
     which you report, (II) a reduction in your level of compensation (including
     base salary, fringe benefits and target bonus under any incentive
     performance plan) or (III) a change in your place of employment which is

          1.13 OPTION means any option granted to you under the Plans which
is outstanding at the time of the Change in Control or your subsequent
Termination.  Your Options will be divided into two (2) separate categories as
follows:

               Acquisition-Accelerated Options: any outstanding Option (or
               -------------------------------                            
     installment thereof) which automatically accelerates, pursuant to the
     acceleration provisions of the agreement evidencing that Option, upon a
     change in control or ownership of the Company under certain specified
     circumstances.

               Severance-Accelerated Options: any outstanding Option (or
               -----------------------------                            
     installment thereof) which accelerates upon your Termination pursuant to
     Section II of this letter agreement.

          1.14 OPTION PARACHUTE PAYMENT means, with respect to any
Acquisition-Accelerated Option or any Severance-Accelerated Option, the portion
of that Option deemed to be a parachute payment under Code Section 280G and the
Treasury Regulations issued thereunder.  The portion of such Option which is
categorized as an Option Parachute Payment will be calculated in accordance with
the valuation provisions established under Code Section 280G and the applicable
Treasury Regulations and will include an appropriate dollar adjustment to
reflect the lapse of your obligation to remain in the Company's employ as a
condition to the vesting of the accelerated installment.  In no event, however,
will the Option Parachute Payment attributable to any Acquisition-Accelerated
Option or Severance-Accelerated Option (or
<PAGE>
 
accelerated installment) exceed the spread (the excess of the Fair Market Value
of the accelerated option shares over the option exercise price payable for
those shares) existing at the time of acceleration.

          1.15 OTHER PARACHUTE PAYMENT means any payment in the nature of
compensation (other than the benefits to which you become entitled under Section
II of this letter agreement) which are made to you in connection with the Change
in Control and which accordingly qualify as parachute payments within the
meaning of Code Section 280G(b)(2) and the Treasury Regulations issued
thereunder.  Your Other Parachute Payments will include (without limitation) the
Present Value, measured as of the Change in Control, of the aggregate Option
Parachute Payment attributable to your Acquisition-Accelerated Options (if any).

          1.16 PLANS means (i) the Company's 1992 Stock Option Plan, (ii) the
Company's 1995 Stock Option/Stock Issuance Plan, as amended or restated from
time to time, and (iii) any successor stock incentive plan subsequently
implemented by the Company.

          1.17 PRESENT VALUE means the value, determined as of the date of
the Change in Control, of any payment in the nature of compensation to which you
become entitled in connection with the Change in Control or the subsequent
Termination of your employment, including (without limitation) the Option
Parachute Payment attributable to your Severance-Acceleration Options, your
Severance Payments under Section II of this letter agreement and the Option
Parachute Payment attributable to your Acquisition-Accelerated Options.  The
Present Value of each such payment will be determined in accordance with the
provisions of Code Section 280G(d)(4), utilizing a discount rate equal to one
hundred twenty percent (120%) of the applicable Federal rate in effect at the
time of such determination, compounded semi-annually to the effective date of
the Change in Control.

          1.18 SEVERANCE PAYMENTS means the severance payments to which you may
become entitled under Section II in the event of a Termination following a
Change in Control, subject, however, to the dollar limitations of Section III.

          1.19 TERMINATION means a Voluntary Resignation or an Involuntary
Termination of your employment.

          1.20 VOLUNTARY RESIGNATION means a resignation by you other than
one which constitutes an Involuntary Termination.

following a Change in Control, you will become entitled to receive the special

          You will be entitled to a Severance Payment in an amount equal to two
(2) times your Base Salary.

          (B)  BONUS

equal to the GREATER of the following bonus amounts: (a) two (2) times the full
amount of the target bonus payable to you with respect to the fiscal year in
which the Termination occurs or (b) two (2) times the full amount of the target
bonus payable to you with respect to the fiscal year in which the Change in
Control occurs.

          (C)  PAYMENT OF SEVERANCE PAYMENTS

          In the absence of a Hostile Take-Over, your Severance Payments will be
made at bi-weekly intervals following your Termination.  However, these payments
will immediately terminate in the event you fail to abide by the restrictive
covenants set forth in Paragraph 2.4.

          Should your Termination occur in connection with a Hostile Take-Over,
the Severance Payments will be made to you in a lump sum payment within thirty
(30) days after your Termination and the provisions of Paragraph 2.4 will not
apply.

          All Severance Payments will be subject to the Company's collection of
all applicable federal and state income and employment withholding taxes.

          2.2  OPTION ACCELERATION
               -------------------

          Each of your outstanding Options will (to the extent not then
otherwise fully exercisable) automatically accelerate so that each such Option
will become fully vested and immediately exercisable for the total number of
shares of Common Stock at the time subject to that Option.  Each such
accelerated Option, together with all your other vested Options, will
<PAGE>
 
remain exercisable for fully-vested shares until the earlier of (i) the

Option.

          2.3  ADDITIONAL BENEFITS

after the date of your Termination or (ii) the first date that you are covered
under another employer's health benefit program which provides substantially the
same level of benefits without exclusion for pre-existing medical conditions.
The coverage so provided you and your eligible dependents will be in full and
complete satisfaction of the continued health care coverage to which you or your
eligible dependents would otherwise, at your own expense, be entitled under Code
Section 4980B by reason of your termination of employment.

          (B)  UNPAID BENEFITS

          You will receive an immediate lump sum payment of all unpaid vacation

          For the twenty-four (24)-month period following your Termination, you
will not:

               (i) directly or indirectly, whether for your own account or as an
     employee, director, consultant or advisor, provide services to any business
     enterprise which is at the time in competition with any of the Company's
     then-existing or formally planned product lines and which is located
     geographically in an area where the Company maintains substantial business
     activities;

               (ii) directly or indirectly encourage or solicit any individual
     to leave the Company's employ for any reason or interfere in any other
     manner with the employment relationships at the time existing between the
     Company and its current or prospective employees; or

               (iii)  induce or attempt to induce any customer, supplier,
     distributor, licensee or other business affiliate of the Company to cease
     doing
<PAGE>
 
     business with the Company or in any way interfere with the existing
     business relationship between any such customer, supplier, distributor,
     licensee or other business affiliate and the Company.

          You acknowledge that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason of
your breach of the foregoing restrictive covenants.  Accordingly, in the event
of any such breach, the Company will, in addition to the cessation of the
severance benefits provided under this agreement and any remedies available to
the Company at law, be entitled to obtain equitable relief in the form of an
injunction precluding you from continuing to engage in such breach.

          None of the foregoing restrictive covenants will be applicable in the
event your Termination occurs in connection with a Hostile Take-Over.

          Should the aggregate Present Value (measured as of the Change in

the time of your Termination (namely the Severance Payments, the Option
Parachute Payment attributable to your Severance-Accelerated Options and your
Health Care Continuation) and (ii) all Other Parachute Payments to which you are
entitled, exceed 2.99 times your Actual Average Compensation (the "Parachute
Limit") and thereby result in an excise tax liability under Section 4999 of the
Code, then the Company will provide you with a full tax gross-up with respect to
such excise tax liability.  The amount of such tax gross-up will be determined
pursuant to the following formula:

               X  =  Y /  1 - (A + B + C), where

               X is the total dollar payment (the "Tax Gross-Up") required to be
               paid under this letter agreement,

               Y is the total excise tax (the "Parachute Tax") imposed on you
               pursuant to Section 4999 of the Code (or any successor provision)
               with respect to the Severance Payments, the Option Parachute
               Payment attributable to your Severance-Accelerated Options, your
               Health Care Continuation and all Other Parachute Payments,

               A is the excise tax rate in effect under Section 4999 of the Code
               for excess parachute payments,
<PAGE>
 
               B is the highest combined marginal federal income and applicable
               state income tax rate in effect for you, after taking into
               account the deductibility of state income taxes against federal
               income taxes to the extent allowable, for the calendar year in
               which the Tax Gross-Up is paid, and

               C is the applicable Hospital Insurance (Medicare) Tax Rate in
               effect for you for the calendar year in which the Tax Gross-Up is
               paid.

          3.2  INITIAL PAYMENT
               ---------------

          Within ninety (90) days after each determination is made by the
Internal Revenue Service or your tax advisor that you have received a parachute
payment for which you are liable for a Parachute Tax, you will identify the
nature of such parachute payment to the Company and submit to the Company the
calculation of the Parachute Tax attributable to that payment and the Tax Gross-
Up to which you are entitled with respect to such tax liability.  The Company
will pay such Tax Gross-Up to you (net of all applicable withholding taxes,
including any taxes required to be withheld under Section 4999 of the Code)
within ten (10) business days after your submission of the calculation of such
Parachute Tax and the resulting Tax Gross-Up, provided such calculations
represent a reasonable interpretation of the applicable law and regulations.

          3.3  FINAL DETERMINATION
               -------------------

          In the event that your actual Parachute Tax liability is determined by
a Final Determination to be greater than the Parachute Tax liability taken into
account for purposes of the Tax-Gross-Up paid pursuant to this Section, then
within ninety (90) days following the Final Determination, you will submit to
the Company a new Parachute Tax calculation based upon the Final Determination.
Within ten (10) business days after receipt of such calculation, the Company
will pay you the additional Tax Gross-Up attributable to such excess Parachute
Tax liability.

          3.4  REFUND
               ------

          In the event that your actual Parachute Tax liability is determined by
a Final Determination to be less than the Parachute Tax liability taken into
account for purposes of the Tax Gross-Up paid to you pursuant to this Section,
then you will refund to the Company, promptly upon receipt, any federal or state
tax refund attributable to the Parachute Tax overpayment.
<PAGE>
 
          3.5  DEFINITION
               ----------

          For purposes of this section, a Final Determination means an audit
adjustment by the Internal Revenue Service that is either agreed to by you or
your estate or an adjustment that is sustained by a court of competent
jurisdiction in a decision with which you concur or with respect to which the
period within which an appeal may be filed has lapsed without a notice of appeal
being filed.

                     SECTION IV - MISCELLANEOUS PROVISIONS

          4.1  DEATH
               -----

          In the event of your death, the Severance Payments (including the
Parachute Payments) to which you become entitled under this letter agreement
will be made, on the due date hereunder, to the executors or administrators of
your estate.  Should you die before you exercise all your outstanding Options,
then such Options may be exercised, within twelve (12) months after your death,
by the executors or administrators of your estate or by persons to whom the
Options are transferred pursuant to your will or in accordance with the laws of
inheritance. In no event, however, may any such Option be exercised after the
specified expiration date of the option term.

          4.2  GENERAL CREDITOR STATUS
               -----------------------

          The payments and benefits to which you become entitled hereunder will
be paid, when due, from the general assets of the Company, and no trust fund,
escrow arrangement or other segregated account will be established as a funding
vehicle for such payment.  Accordingly, your right (or the right of the personal
representatives or beneficiaries of your estate) to receive any payments or
benefits hereunder will at all times be that of a general creditor of the
Company and will have no priority over the claims of other general creditors.

          4.3  INDEMNIFICATION
               ---------------

          The indemnification provisions for officers and directors under the
Company certificate of incorporation, indemnification agreement, Bylaws and
insurance policies will (to the maximum extent permitted by law) be extended to
you with respect to any and all matters, events or transactions occurring or
effected during your employment with the Company.
<PAGE>
 
          4.4  MISCELLANEOUS
               -------------

          This letter agreement will be binding upon the Company, its successors
and assigns (including, without limitation, the surviving entity in any Change
in Control) and is to be construed and interpreted under the laws of the State
of California.  Except as set forth herein, this letter agreement supersedes all
prior agreements between you and the Company relating to the subject of
severance benefits payable upon a change in control or ownership of the Company,
including the Plans and the agreements evidencing the Options, and may only be
amended by written instrument signed by you and an authorized officer of the
Company.  If any provision of this letter agreement as applied to any party or
to any circumstance should be adjudged by a court of competent jurisdiction to
be void or unenforceable for any reason, the invalidity of that provision will
in no way affect (to the maximum extent permissible by law) the application of
such provision under circumstances different from those adjudicated by the
court, the application of any other provision of this letter agreement, or the
enforceability or invalidity of this letter agreement as a whole.  Should any
provision of this letter agreement become or be deemed invalid, illegal or
unenforceable in any jurisdiction by reason of the scope, extent or duration of
its coverage, then such provision will be deemed amended to the extent necessary
to conform to applicable law so as to be valid and enforceable or, if such
provision cannot be so amended without materially altering the intention of the
parties, then such provision will be stricken and the remainder of this letter
agreement will continue in full force and effect.

          4.5  ATTORNEY FEES
               -------------

          In the event legal proceeding should be initiated by you or by the
Company with respect to any controversy, claim or dispute relating to the
interpretation or application of the provisions of this letter agreement or any
benefits payable hereunder, the prevailing party in such proceedings will be
entitled to recover from the losing party reasonable attorney fees and costs
incurred in connection with such proceedings or in the enforcement or collection
of any judgment or award rendered in such proceedings.  For purposes of this
provision, the prevailing party means the party determined by the court to have
most nearly prevailed in the proceedings, even if that party does not prevail in
all matters, and does not necessarily mean the party in whose favor the judgment
is actually rendered.  If the Company materially breaches any of its obligations
under this letter agreement and fails to cure that breach within thirty (30)
days after written notice from you, you will then be entitled to reimbursement
from the Company for any reasonable expenses and attorney fees you incur in
having the Company subsequently cure that breach, whether or not legal
proceedings are actually commenced in connection with such breach.

          4.6  INDEPENDENT LEGAL COUNSEL
               -------------------------

          By executing this letter agreement, you acknowledge that (i) this
agreement has been prepared by Brobeck, Phleger & Harrison LLP ("Brobeck")
acting it its capacity as legal counsel to the Company and (ii) you have had an
opportunity to seek advice from your own legal counsel with respect to the
matters contained herein and such individual counsel is not Brobeck.

          Please indicate your acceptance of the foregoing provisions of this
letter agreement by signing the enclosed copy of this agreement and returning it
to the Company.

"P-COM"

and

SIEMENS TELECOMUNICAZIONI S.P.A. a corporation under the law of Italy and having
its registered office at 20060 Cassina de' Pecchi, Italy, S.S. Padana Superiore
km. 158, hereinafter referred to as "Siemens"

(P-COM and Siemens are hereinafter referred to jointly as the "Parties" and
individually as a "Party")

whereas P-COM has developed the Tel-Link radio Product Line presently covering
the 23, 38 and 50 GHz frequency bands and allowing the transport of one or more
1.5 (T1) or 2 (E1) Mbit/s traffic signals;

whereas Siemens is willing to introduce the products of the Tel-Link Product
Line into its own catalogue and to place orders to buy certain amounts of these
products;

being the recitals hereinabove integral part of the present Agreement


                   NOW THEREFORE THE PARTIES AGREE AS FOLLOWS
                                        

ARTICLE 1. PURPOSE OF THE AGREEMENT

1.1 The purpose of this Agreement is to set forth rules that allow Siemens to
include the Tel-Link Product Line (hereinafter "the Products", which terms shall
also be construed as designating equipment, subset, assembly or part of the Tel-
Link Product Line where The context so admits) in its products catalogue.

1.2 As a consequence P-COM agrees to Sell and Siemens agrees to buy the Products
in accordance with purchase orders that may be issued from time to time by
Siemens to The price, terms and conditions herein contained.

ARTICLE 2. SPECIFICATIONS OF THE PRODUCTS AND RELEVANT SIEMENS ACCEPTANCE TEST

2.1 P-COM grants that the characteristics and specifications of the Products at
the date of the Agreement are those listed in the Attachment I hereto.

                                  Page 1 of 9
<PAGE>
 
2.2  In the spirit of the present Agreement, should P-COM decide to modify the
Products with enhancements or extensions, P-COM is willing to make available to
Siemens the above mentioned enhancements and extensions and to timely provide
Siemens with sufficient information and documentation in order to promote the
enhanced and extended Products in the market.

2.3  if the enhanced Products should not grant full backword compatibility, P-
COM undertakes to produce the previous version of the Products for Siemens for a
minimum period of 24 months after the commercial availability of the enhanced
Products.

2.4 The characteristics and conditions related with the Quality Assurance are
detailed in the Attachment 2 hereto.


ARTICLE 3. MARKETING RIGHTS

3.1 Siemens will have the non exclusive right to promote, sell or lease, as a
single equipment or together with other products or systems, the Products in any
market freely and with no limitations.

3.2 Siemens will have the right to include the Products in its catalogue with
Siemens trade-mark and brand name. To this purpose P-COM agrees to deliver to
Siemens the Products properly marked and externally coloured in accordance with
Siemens' instructions, provided that such instructions will not be in conflict
with the production process of the Products.

3.3 P-COM warrants that it does not have nor will undertake any obligation with
anybody conflicting with the rights granted to Siemens pursuant to this
Agreement


ARTICLE 4. PRICES

4.1 The prices from P-COM to Siemens of the Product are given in the Attachment
3 to this Agreement. Prices are fixed throughout each calendar year and will be
revised annually in a joint meeting to be held by the Parties by 30th of
September of the previous year. Basic criterion adopted in defining price is to
allow Siemens to withhold a reasonable margin, estimated by the Parties in
approximately *** on the most competitive market price recognized by the Parties
provided P-COM can also obtain a reasonable margin.

4.2 Price vs. quantity matrix is given in the Attachment 3, based on the total
number of transmitters/receivers of the Products ordered by Siemens for delivery
within the year.
The initial price level of each year will be defined during the annual meeting
according to the quantity objective indicated by Siemens.

In case after six months of each year the total ordered transmitter/receiver do
not reach *** **** ****** of the minimum quantity of the initial price level,
The purchase order price for the second six months will automatically switch to
the lower quantity level.

Viceversa, whenever during a year Siemens inform P-COM that the total expected
ordered quantity for the same year would exceed the minimum of the initial price
level agreed for that year, the purchase order price will switch to the higher
quantity level three months after the notification by Siemens of the higher
volume.

For year 1995 the initial price level will be level * while the quantities in
Attachment 3 have to be considered reduced by *** **** ******.

4.3 In the event that during the one year time frame of validity of certain
price levels, the competitive market price - which is used as reference in
defining price - reduces considerably, the Parties agree to meet and jointly
review the price in accordance with such modified market conditions and
following the basic criterion indicated at point 4.1.

delayed batch per week of delay without exceeding *** **** ******** of said
price. P-COM shall inform immediately Siemens in the event it anticipates any
delay in its deliveries and the Parties shall make their best efforts to
minimise the consequences thereof.

If due to joint efforts of the Parties, the delay in P-COM deliveries does not
delay Siemens' performance of its obligation towards its customer and therefore
no penalties are charged to Siemens, P-COM may elect to reimburse in full to
Siemens all extra or special costs incurred by Siemens during above mentioned
joint efforts instead of being charged penalties hereunder.

In the event Siemens cancels or delays by more than three months any shipment
firmed up in the first three months of the rolling forecast, P-COM will make its
best efforts to redirect the shipment elsewhere to the extent possible. Failing
that P-COM shall inform Siemens in writing within 1 week and Siemens will be

Products require a local content (either explicitly or as a competitive
advantage), P-COM and Siemens will jointly analyse and decide the best strategy
to be followed with respect to the granting of the manufacturing rights to the
third party addressed in the specific project. Terms and conditions for the
above manufacturing transfer will be negotiated in good faith by the Parties.

Section 8:   Loopbacks:                      Three types of loopbacks are
                                             offered:

     IDU Loopback:                           Loops the aggregate date before the
                                             "N" connector of the IDU. Tests all
                                             circuits in the IDU for operation.
                                             An external BERT set is needed to
                                             test for error performance. Traffic
                                             affecting on all tributaries.

     ODU Loopback:                           Used only with the Loopback Test
                                             Transistor (LBT) to allow testing
                                             of an entire terminal. The LBT
                                             consists of a number and a 1008 or
                                             1232 MHz oscillator.

     Link Loopback:                          Loops the far end tributary at the
                                             line driver and returns the E1
                                             signal to the local end. Affects
                                             only the tributary selected. An
                                             external BERT set is needed to
                                             perform error rate tests.

                                          solid yellow when far end terminal is
                                          not in normal operation.

External Alarms:                          Up to eight external alarms can be
                                          used per IDU for site alarms such as
                                          Open door, Temperature, A/C Fail, etc.

Alarm Relays:                             Five form "C" relays. These alarm
                                          relays can be "mapped" using the
                                          optional P.C. software.

Transmit Mute:                            The alarms that will cause the 
                                          transmitter to mute are:
                                          Modulator
                                          LO/Synthesizer

   Alarm Clearing to Tx Output Restoral:  * seconds

Resulting Power Reduction:                * dB


Section 8:     Loopbacks:                 Three types of loopbacks are offered:

   IDU Loopback:                          Loops the aggregate date before the 
                                          "N" connector of the IDU. Tests all 
                                          circuits in the IDU for operation. An 
                                          external BERT set is needed to test 
                                          for error performance. Traffic 
                                          effecting on all tributaries.

   ODU Loopback:                   Used only with the Loopback Test Translator 
                                   (LBT) to allow testing of an entire 
                                   terminal. The LBT consists of a mixer and a 
                                   1280 MHz oscillator.

   Link Loopback:                  Loops the far end tributary at the line 
                                   driver and returns the E1 signal to the 
                                   local end. Affects only the tributary 
                                   selected. An external BERT set is needed to 
                                   perform error rate tests.

8.11    INSPECTION AND TEST STATUS - QAP 4.12(03.70.012)

        The inspection and test status of product during the process and
        assembly stages of the operation is identified by unique routing card.
 
        A unique routing card is provided for each defined module, subassembly
        or product recording its progress through the manufacturing process and
        its conformance to inspection and tests performed.

        The Quality Assurance Manager is responsible for the release of
        conforming product.

8.12    CONTROL OF NON-CONFORMING PRODUCT - QAP 4.13(03.70.013)

        identification, segregation and disposition in accordance with
        documented procedures.

8.12.1  NON-CONFORMANCE REVIEW AND DISPOSITION

        In the documented procedures, the Quality Engineer is responsible for
        the review of Non-conformance Reports with other members of the Company
        Material Review Board to determine the appropriate disposition of non-
        conforming material and product.

        A Deviation Authorization may be requested from the customer for non-
        conforming product that is proposed for use or repair.

8.13    CORRECTIVE ACTION - QAP 4.14(03.70.014)

        The Company maintains documented procedures for the investigation and

        control the receipt and issuing of materials.

        Lists of materials requiring special storage conditions, or having a
        limited shelf life are maintained and controls applied to conform with
        requirements. The materials requiring special storage conditions are
        maintained in the appropriate environment and materials having limited
        shelf life are discarded in an approved manner when shelf life has
        expired. Material Safety Data Sheet regulations are applied for storage
        and handling of material. Lists of such materials are maintained.

8.14.4  PACKAGING

        Company Standards and Procedures control the marking and packaging of
        the product to ensure conformance to specified contract requirements.

8.14.5  DELIVERY

        After final inspection and test, documented procedures provide for the
        protection of the product in stores and during delivery to the customer.

        Delivery documentation is provided and instructions are carried out in
        accordance with specified contract requirements.

8.15    QUALITY RECORDS - QAP 4.16 (03.70.016)

        The quality records identified in the Quality Assurance Procedures are
        filed and maintained by the applicable department and are under the
        jurisdiction of the Quality Assurance Manager for demonstration of the
        Quality System effectiveness.

        The records are retained for a minimum of five years or for a period
        specified by customer contract.

8.16    INTERNAL QUALITY AUDITS - QAP 4.17(03.70.017)

        All quality activities are subject to a planned and documented audit to
        verify compliance with the defined Quality System.

        Audits are conducted at predetermined intervals and are carried out by
        trained personnel under the control of the Quality Assurance Manager.

        The results of these audits are recorded and used to improve the
        effectiveness of the Quality System.

8.17    TRAINING - QAP 4.18 (03.70.018)

        The Company maintains procedures for identifying the training needs of

        quality awareness.

        Training records are held for each employee registering their education,
        experience and training requirements.

8.18    SERVICING

        The design philosophy of products manufactured by the Company precludes
        the need for regular maintenance. Servicing procedures are therefore not
        required.

8.19    STATISTICAL TECHNIQUES - QAP 4.20(03.70.019)

        The Company promotes the use of statistical tools and techniques in a
