                               PROSPECTUS SUMMARY

       BECAUSE THIS IS ONLY A SUMMARY, IT DOES NOT CONTAIN ALL OF THE
INFORMATION THAT MAY BE IMPORTANT TO YOU. YOU SHOULD READ THE ENTIRE PROSPECTUS,
INCLUDING "RISK FACTORS," AND THE CONSOLIDATED FINANCIAL STATEMENTS AND THE
NOTES THERETO, BEFORE DECIDING TO INVEST IN OUR COMMON STOCK.

                                   OUR COMPANY

       We are a global provider of broadband wireless access solutions that
enable Internet and communication service providers, telephone operating
companies and private network operators to deliver voice and high-speed data
services to their customers. We provide a portfolio of wireless systems that
connect end-users to public and private telecommunication networks in domestic
and international markets. Our systems allow an Internet or communication
service provider or enterprise to rapidly install high-speed communications
throughout a service area at a lower cost than a comparable wired network. More
than 200 customers in over 50 countries have purchased and installed our
systems.

       Our portfolio of systems allows end-users to transmit voice and data
simultaneously via Internet protocol, or IP, or asynchronous transfer mode, or
ATM, architectures, two leading industry standards for telecommunication
transport. Our broadband wireless access solutions address a wide range of
applications in different markets, including:

       o enabling Internet service providers to offer direct Internet access;

       o rapidly installing new networks for communication service providers;

       o supplementing telephone operating companies' existing wired networks;

       o establishing communication networks in regions without existing
         infrastructures; and

       o establishing private corporate networks.

       Our systems are available in a broad range of frequency assignments,
enabling us to address the different regulatory requirements of multiple
geographic markets. We have systems installed and operating in Argentina,
Brazil, Chile, China, Mexico, Panama, the Philippines, Poland and the United
States. In 1999, 83% of our revenues were derived internationally. Our global
service organization provides customer support 24 hours per day, 7 days a week
and offers network design and installation services as part of our wireless
solution.

       As the Internet and public and private communication networks have become
essential for communication, e-commerce and information exchange, the volume of
voice and high-speed data traffic worldwide has increased dramatically. In
addition, user applications, such as electronic mail, telecommuting and
business-to-business exchanges have further increased the amount of network
traffic. This increase in network traffic has resulted in a demand for greater
transmission capacity, or bandwidth, and high-speed, or broadband services to
support it. Bandwidth limitations between service providers' central offices and
end-users, often referred to as the last mile bottleneck, have constrained
service providers from delivering broadband services to end-users. We believe
that traditional dial-up modem technology is insufficient to support the growth
in network traffic and demand for high-speed data transmission. Although wired
access network infrastructures using cable, digital subscriber line, or DSL, and
fiber optic systems can deliver greater bandwidth than that provided by dial-up
modem technology, these systems are not universally available to end-users. This
last mile bottleneck is frustrating a broad base of business, residential and
small office/home office users, many of whom require high-speed access to data.

       Broadband wireless access technology can solve many of the problems
imposed by wired networks. Broadband wireless technology enables rapid
implementation of high-speed network access in a cost-effective manner relative
to wired networks. We believe that wireless network providers will be able to
gain a greater share of the network access market because, unlike wired network
providers, they are not required by federal law to share their wireless networks
with competing service providers. A broadband wireless network is often the best
option for high-speed communication in remote areas and in many developing
countries due to the lack of an existing wired infrastructure. In these regions,
wireless technologies provide clear advantages over wired networks, including
lower cost, faster installation, greater flexibility and increased reliability.

       We believe our WAVENET BROADBAND WIRELESS ACCESS portfolio of systems
provides our customers with the following key benefits:

       o cost-effective design and implementation;

       o rapid installation;

       o scalability;

       o remote management; and

       o network compatibility.

       Our goal is to be the global broadband wireless access solution of choice
for Internet and communication service providers, telephone operating companies
and private network operators. Our strategy for achieving this goal includes the
following core elements:

       o introducing new wireless access technologies;

       o leveraging strategic relationships;

       o expanding global market presence;

       o emphasizing research and development; and

       o continuing to deliver high-quality customer service and support.

       As part of our strategy, we are expanding our product line. We are
currently testing in the field a new system called STARPORT which we intend to
commercially introduce during 2000. STARPORT is a point-to-multipoint broadband
wireless access system that does not require a line of sight between
transmission and reception points and supports high-speed Internet traffic.
STARPORT can be installed by the consumer without requiring a communication
service provider to supply a professional technician. STARPORT is designed as a
cost-effective alternative to wire-based cable, DSL and fiber optic
technologies, and is intended to allow a service provider to rapidly supply
services, such as high-speed Internet access, throughout a service area.
STARPORT is specifically designed for the residential, small office and home
office markets. We expect that the consumer will be able to connect an interface
cable from STARPORT to a personal computer and then automatically receive
broadband service at data rates that are comparable to typical DSL service.

       We have entered into a strategic relationship with TRW, Inc. which
provides us with technology that we use in our STARPORT system. This technology
was originally developed by TRW Systems and Information Technology Group for
military communications. TRW is an international company that provides advanced
technology products and services. The principal businesses of TRW and its
subsidiaries are the design, manufacture and sale of products and the
performance of systems engineering, research and technical services for industry
and the United States Government in the automotive, aerospace and information
systems markets. As part of this initiative, TRW acquired approximately 18% of
our capital stock outstanding prior to this offering.

       Despite our accomplishments, we face many challenges and risks. For
example, we have not achieved, and may never achieve, profitability. In
addition, we expect to incur net losses in the future and these losses may be
substantial. Accordingly, you should carefully consider the information set
forth under the caption "Risk Factors" before deciding to purchase our common
stock.

                                 OUR BACKGROUND

       Wireless, Inc. was incorporated on May 7, 1997 in California and in
August 1998 purchased Multipoint Networks, Inc., a California corporation
engaged in the manufacturing of point-to-multipoint data products. We plan to
reincorporate in Delaware prior to the commencement of this offering. References

                                  RISK FACTORS

       YOU SHOULD CAREFULLY CONSIDER THE RISKS AND UNCERTAINTIES DESCRIBED BELOW
AND THE OTHER INFORMATION IN THIS PROSPECTUS BEFORE DECIDING WHETHER TO INVEST
IN SHARES OF OUR COMMON STOCK. IF ANY OF THE FOLLOWING RISKS OCCUR, OUR BUSINESS
AND FINANCIAL RESULTS MAY SUFFER. IN THAT CASE, THE TRADING PRICE OF OUR COMMON
STOCK COULD DECLINE AND YOU MAY LOSE PART OR ALL OF YOUR INVESTMENT.

                          RISKS RELATING TO OUR COMPANY

OUR PROSPECTS ARE DIFFICULT TO EVALUATE BECAUSE WE HAVE ONLY BEEN OPERATING OUR
BUSINESS SINCE MAY 1997.

       We were incorporated in May 1997 and did not ship our first wireless
access product until September 1998. We have limited meaningful historical
financial data upon which to base projected revenues and planned operating
expenses and upon which investors may evaluate us and our prospects. In
addition, our operating expenses are largely based on anticipated revenue trends
and a high percentage of our expenses are and will continue to be fixed. You
should consider the risks and difficulties frequently encountered by companies
like ours in a new and rapidly evolving market. Our ability to sell products and
the level of success we achieve depends on the level of demand for broadband
wireless access and networking products, which is a new and rapidly evolving
market.

WE HAVE A HISTORY OF LOSSES, EXPECT FUTURE LOSSES AND MAY NEVER ACHIEVE OR
SUSTAIN PROFITABILITY.

       As of December 31, 1999, we had an accumulated deficit of $24.8 million,
and we expect to continue to incur net losses. We anticipate continuing to incur
significant sales and marketing and general and administrative expenses and
significantly increasing our research and development expenses as a result of
products under development. As a result, we will need to generate significantly
higher revenues to achieve or sustain profitability and we cannot be certain
that we will be able to generate these revenues. We incurred net losses of $3.6
million, $7.5 million and $13.7 million in 1997, 1998 and 1999, respectively. We
expect to continue to incur net losses for the foreseeable future.

FLUCTUATIONS IN OUR OPERATING RESULTS MAY ADVERSELY AFFECT THE TRADING PRICE OF
OUR COMMON STOCK.

       Our operating results have varied in the past and are likely to vary in
the future. It is possible that our revenues and operating results may be below
the expectations of securities analysts or investors in future quarters. If we
fail to meet or surpass the expectations of securities analysts or investors,
the market price of our stock will most likely fall. Fluctuations in our
operating results could be caused by a number of factors, including:

       o the timing and cancellation of customer orders;

       o our ability to introduce new systems and technologies on a timely
         basis;

       o market acceptance of our systems and our customers' services;

       o introduction of products and systems by our competitors;

       o our ability to respond to fluctuations in customer order levels;

       o the timing of our investments in research and development;

       o the timing and provision of returns from our distributors;

       o whether our customers buy from a distributor, an original equipment
         manufacturer or directly from us;

       o cost and availability of components and subassemblies;

       o competitive pressures on selling prices;

       o finished system availability and quality;

       o general economic conditions; and

       o changes in system mix.

       Given that any one or more of those factors could have an adverse effect
on our business, the prediction of future operating results is difficult and
uncertain. In addition, some of our operating expenses are relatively fixed


                                       8
<PAGE>


and, as a result, we may not be able to reduce our operating costs in response
to unanticipated reductions in our revenues or the demand for our systems.

WE DEPEND UPON TECHNOLOGY LICENSED FROM THIRD PARTIES, AND IF WE DO NOT MAINTAIN
THESE LICENSE ARRANGEMENTS, OUR BUSINESS WILL BE SERIOUSLY HARMED.

       We license technology that is used in our broadband wireless access
systems from third parties under agreements with a limited duration and we may
not be able to maintain these license arrangements. If we fail to maintain these
license arrangements or we are unable to maintain these licenses on affordable
terms, we would not be able to ship our systems for the broadband wireless
access market, and our business would be seriously harmed.

OUR BUSINESS MODEL DEPENDS UPON OBTAINING AND PROTECTING OUR INTELLECTUAL
PROPERTY, AND IF WE FAIL TO PROTECT OUR PROPRIETARY RIGHTS, OUR BUSINESS COULD
BE HARMED.

       Our ability to compete depends substantially upon our internally
developed technology, and, in particular, upon our ability to obtain and
preserve patent and other intellectual property rights covering our systems and
development and testing tools. Our efforts to obtain patent, trade secret,
copyright and other intellectual property rights in connection with our products
are likely to be expensive, may not be effective and may have unpredictable
consequences. If we are not successful in protecting our intellectual property,
our business could be substantially harmed.

       OUR PENDING PATENTS MAY NEVER BE ISSUED, AND EVEN IF ISSUED, MAY PROVIDE
       US WITH LITTLE PROTECTION.

       We regard the protection of patentable inventions as important to our
future opportunities. We currently hold two U.S. patents and have two patent
applications pending before the U.S. Patent and Trademark Office relating to our
point-to-multipoint wireless networking technology. We also share ownership of
two patent applications pending before the U.S. Patent and Trademark Office,
obtained under a Purchase and License Agreement with TRW, relating to our
STARPORT point-to-multipoint wireless networking technology. In addition, under
the Purchase and License Agreement with TRW, we obtained rights in technology in
the field of wireless communications systems that may lead to additional patent
applications. However, none of our technology is patented outside of the United
States nor do we currently have any international patent applications pending.
We cannot assure you that:

       o patents will be issued from our currently pending or future
         applications;

       o our existing patents or any new patents will be sufficient in scope to
         provide meaningful protection or any commercial advantage to us;

       o an issued patent will not be successfully challenged by one or more
         third parties, resulting in our loss of the right to prevent others
         from exploiting the inventions claimed in the patents;

       o foreign intellectual property laws will protect our intellectual
         property rights; or

       o others will not independently develop similar or superior products,
         duplicate our products or design around any patents issued to us.

       TO PROTECT OUR PROPRIETARY RIGHTS, WE RELY UPON TRADEMARKS, COPYRIGHTS
       AND TRADE SECRETS, WHICH ARE ONLY OF LIMITED VALUE.

       We rely on a combination of laws, such as copyright, trademark and trade
secret laws, and contractual restrictions, such as confidentiality agreements
and licenses, to establish and protect our proprietary rights. We currently have
registered trademarks for the marks "WAVENET," and "RAN" and applications
pending before the United States Patent and Trademark Office for additional
marks, including "STARPORT," and the Wireless logo. However, none of our
trademarks are registered outside of the United States, nor do we have any
trademark applications pending outside of the United States. Moreover, despite
any precautions which we have taken:

       o laws and contractual restrictions may not be sufficient to prevent
         misappropriation of our technology or deter others from developing
         similar technologies;

       o other companies may claim common law trademark rights based upon state
         or foreign law which precede our federal registration of such marks;
         and


                                       9
<PAGE>


       o policing unauthorized use of our systems and trademarks is difficult,
         expensive and time-consuming and, therefore, we are unable to determine
         the extent to which piracy of our systems and trademarks may occur,
         particularly overseas.

       The establishment of trade secrets, proprietary know-how and copyright
rights used in our business relies upon confidentiality and other provisions in
agreements with employees, consultants and other contracting parties. Such
contracting parties may not comply with the terms of their agreements with us
and we may not be able to adequately enforce our rights or, if enforceable, the
remedies may be inadequate. In contracts with our suppliers, customers and
others, we usually include indemnification provision concerning intellectual
property matters. We cannot assure you that the indemnification that we receive
will be adequate nor that the indemnification that we give will not harm our
business.

       See "Business--Intellectual Property and Proprietary Rights."

WE MAY BECOME INVOLVED IN COSTLY AND TIME CONSUMING LITIGATION OVER PROPRIETARY
RIGHTS.

       Substantial litigation regarding intellectual property rights exists in
our industry. Intellectual property rights are uncertain and involve complex
legal and factual questions. We expect that software and hardware in our
industry may be increasingly subject to third-party infringement claims as the
number of competitors grows and the functionality of products in different
industry segments overlaps. Third parties may currently have, or may eventually
be issued, patents that would be infringed by our products or technology. We
cannot be certain that any of these third parties will not make a claim of
infringement against us with respect to our products and technology.

       In particular, our STARPORT system under development relies upon direct
sequence spread spectrum technology. There are a number of patents relating to
this technology held by different companies which may impact our STARPORT
system. If our STARPORT system infringes any of these patents and we are unable
to negotiate a license, then we may be required to redesign the STARPORT system
or we may not be able to sell it.

       Any litigation, brought by us or others, could result in the expenditure
of significant financial resources and the diversion of management's time and
efforts. In addition, litigation in which we are accused of infringement may
cause product shipment delays, require us to develop non-infringing technology
or require us to enter into royalty or license agreements even before the issue
of infringement has been decided on the merits. If any litigation were not to be
resolved in our favor, we could become subject to substantial damage claims and
be enjoined from the continued use of the technology at issue without a royalty
or license agreement. These royalty or license agreements, if required, might
not be available on acceptable terms, or at all, and could harm our business. If
a successful claim of infringement were made against us and we could not develop
non-infringing technology or license the infringed or similar technology on a
timely and cost-effective basis, our business could be significantly harmed.

WE CURRENTLY SELL A LIMITED NUMBER OF SYSTEMS. OUR SUCCESS DEPENDS ON SALES OF
THOSE SYSTEMS AND THE DEVELOPMENT AND SALE OF FUTURE SYSTEMS.

       Our future growth depends on the commercial success of our line of
WAVENET broadband wireless access networking systems and the development and
sale of our WAVENET ACCESS 3500 and STARPORT system lines. Our WAVENET ACCESS
2400, WAVENET ACCESS 2458, WAVENET LINK, WAVENET TRANSPORT, and RAN systems and
those systems that we resell are the only systems that have been shipped to our
customers. We may experience design or manufacturing difficulties that could
delay or prevent our development, introduction or marketing of new systems and
enhancements of existing systems. Any of these difficulties could cause us to
incur unexpected expenses or lose revenue. We cannot assure you that we will
successfully complete the development or introduction of these systems. Failure
of our current or planned systems to operate as expected could delay or prevent
their adoption. If our target customers do not adopt, purchase, and successfully
install our current and planned systems, our revenues will not grow.

IF THE DEVELOPMENT OF OUR STARPORT SYSTEM IS MATERIALLY DELAYED OR FAILS TO
PERFORM TO CUSTOMER EXPECTATIONS, OUR BUSINESS WILL BE SUBSTANTIALLY HARMED AND
WE MAY LOSE OUR EXCLUSIVE LICENSE TO THE TECHNOLOGY.

       We obtained an exclusive license from TRW in January 2000 to use the
technology employed by our STARPORT system in base stations configured for
outdoor use. If we do not offer a commercial version of a product containing


                                       10
<PAGE>


the STARPORT technology for sale by July 14, 2001, unless the delay is the fault
of TRW or attributable to specified reasons, we will lose our exclusivity with
respect to the license. Our future growth depends on the success of our STARPORT
system and we are committed to spending substantial amounts of money to develop
and commercialize products based upon STARPORT technology. If we fail to
successfully commercialize products containing STARPORT technology our prospects
will be severely diminished. Moreover, if we were to lose our exclusivity with
TRW or if our STARPORT system did not perform to customer expectations once we
completed development, our business would be substantially harmed. See
"Business--Strategic Relationship with TRW" and "Certain Transactions--Strategic
Relationship with TRW."

IF THE RADIO FREQUENCY IN WHICH OUR WAVENET ACCESS 3500 SYSTEM OPERATES IS
REASSIGNED, OR IF THE COMMERCIAL RELEASE OF THIS SYSTEM IS DELAYED, OUR BUSINESS
WILL BE SUBSTANTIALLY HARMED.

       We have expended significant resources to design our WAVENET ACCESS 3500
system to operate in this band. We cannot assure you that this frequency band
will remain available for use by point-to-multipoint broadband wireless access
systems by the time we develop and launch this system. The reassignment of the
3.5 GHz frequency band to services other than broadband wireless access
technology would significantly harm our business. Moreover, if the WAVENET
ACCESS 3500 system does not satisfy our customers' expectations or if its
release is materially delayed, our business would be substantially harmed.

IF OUR BROADBAND WIRELESS ACCESS SYSTEMS UNDER DEVELOPMENT DO NOT FUNCTION WELL,
WE COULD LOSE SALES OPPORTUNITIES, SUFFER INJURY TO OUR REPUTATION, OR
EXPERIENCE WARRANTY CLAIMS.

       To date, our broadband wireless access systems under development,
including STARPORT and WAVENET ACCESS 3500, are currently undergoing, or will
soon undergo, trial deployments. These broadband wireless access systems may
contain undetected or unresolved errors when they are first introduced or as a
result of changes we make to reduce manufacturing costs. In addition, these
broadband wireless access systems are integrated with other network elements and
there may be incompatibilities between these elements and our broadband wireless
access systems under development that adversely affect the service provider or
its subscribers. If these broadband wireless access systems fail, or do not
function adequately, we could experience:

       o delays in, or losses of, sales opportunities;

       o diversion of development resources;

       o injury to our reputation; and

       o increased service, warranty and replacement costs.

       In addition, these broadband wireless access systems may contain
undetected or unresolved errors when they are first introduced or as a result of
changes we make to reduce manufacturing costs. These broadband wireless access
systems are integrated with other network elements. There may be
incompatibilities between these elements and our broadband wireless access
systems under development that adversely affect the service provider or its
subscribers.

OUR INTERNATIONAL OPERATIONS MAY BE ADVERSELY AFFECTED BY ADDITIONAL RISKS
UNIQUE TO THOSE MARKETS.

       Revenues from customers outside North America accounted for 83% of our
total revenues for 1999. We anticipate that revenues from customers outside
North America will continue to account for a significant portion of our total
revenues for the foreseeable future. Expansion of our international operations
has required, and will continue to require, significant management attention and
resources. In addition, we remain heavily dependent on distributors to market,
sell and support our systems internationally. Our international operations are
subject to additional risks, which could harm our results of operations,
including the following:

       o difficulties of staffing and managing foreign operations;

       o longer customer payment cycles and greater difficulties in collecting
         accounts receivable;

       o unexpected changes in regulatory requirements, telecommunications
         standards, exchange rates, trading policies, tariffs and other
         barriers;

       o uncertainties of laws and enforcement relating to the protection of
         intellectual property;


                                       11
<PAGE>


       o language barriers;

       o potential adverse tax consequences; and

       o political and economic instability.

       We currently sell broadband wireless access systems to customers in over
50 countries on 6 continents. During 1999, system sales to Mexico totaled $7.6
million or 35.9% of total revenues. System sales to the Philippines totaled $3.0
million or 13.9% of total revenues. One customer in Mexico represented $3.0
million or 13.9% of total revenues in 1999. These countries have recently
experienced significant problems with their economies, which have adversely
affected the value of their currency, availability of credit and their ability
to engage in foreign trade in general. If their economies do not improve, our
ability to collect payments and gain future revenue opportunities may suffer.

       Although all of our sales are currently denominated in U.S. Dollars, we
cannot accurately predict the impact that any future fluctuations in foreign
currency exchange rates may have on our operating results and financial
condition.

WE DEPEND ON CONTRACT MANUFACTURERS AND SOLE-SOURCE SUPPLIERS. IF THESE
MANUFACTURERS OR SUPPLIERS ARE UNABLE TO FILL OUR ORDERS ON A TIMELY BASIS, WE
MAY BE UNABLE TO DELIVER PRODUCTS TO MEET CUSTOMER ORDERS.

       We depend on contract manufacturers and sole-source suppliers to
manufacture our broadband wireless access systems. We operate on a purchase
order basis and do not have long-term supply contracts with our contract
manufacturers. We manufacture only small quantities of products at our own
facilities. If our manufacturers are unable or unwilling to continue
manufacturing our components in required volumes or in the event of a reduction
or interruption of supply or a degradation of quality, we would have to identify
and train acceptable alternate manufacturers, which could take as long as six
months and cause our results of operations to suffer.

       In addition, many of our key components have long lead times, are
purchased from sole-source vendors for which alternate sources are not currently
available, and are complex to manufacture. In the event of an interruption of
supply, or a degradation in quality, as many as six months could be required
before we would begin receiving adequate supplies from alternate suppliers, if
any. As a result, shipments could be delayed and our revenues and results of
operations would suffer. It is possible that a source supplier may not be
available when needed, and we may not be able to satisfy our production
requirements at acceptable prices and on a timely basis, if at all. Any
significant interruption in supply would affect the allocation of our systems to
customers, which in turn could cause us to lose customers and harm our business.

BECAUSE WE DO NOT HAVE LONG-TERM CONTRACTS WITH OUR CUSTOMERS, OUR CUSTOMERS MAY
CEASE PURCHASING OUR SYSTEMS AT ANY TIME.

       We do not have long-term contracts with our customers. As a result, our
agreements with our customers do not provide any assurance of future sales. Our
customers can stop purchasing our systems at any time without penalty. Our
customers are free to purchase systems from our competitors. In addition, in
many cases, our customers are not required to make minimum purchases of our
systems. Sales are typically made pursuant to individual purchase orders, often
with extremely short lead times. If we are unable to fulfill these orders in a
timely fashion, we will lose sales and customers and our business will be
significantly harmed.

MANY NETWORKS THAT INCLUDE OUR SYSTEMS REQUIRE SYSTEM INTEGRATION EXPERTISE AND
THIRD-PARTY FINANCING, WHICH WE ARE UNABLE TO PROVIDE. IF SOURCES FOR SYSTEM
INTEGRATION OR FINANCING CANNOT BE OBTAINED AS NEEDED, CUSTOMERS MAY NOT BUY OUR
SYSTEMS.

       Some customers using our systems purchase them as a part of a larger
network installation program that can require capital expenditures in the
hundreds of millions of dollars. In some circumstances, these customers require
their equipment vendors to integrate equipment into these larger networks and to
finance the installation. We are unable to provide integration services or
financing and will have to rely on the ability of our system integrators and
third parties to integrate or finance these transactions. In the event that we
are unable to identify distributors and system integrators that are able to
provide integration services or financing on our behalf, we would be unable to
compete for the business of some customer accounts and our business would be
harmed.


                                       12

IF WE FAIL TO MANAGE OUR GROWTH, OUR BUSINESS, FINANCIAL CONDITION AND PROSPECTS
COULD BE SERIOUSLY HARMED.

     We have expanded our operations in recent years and we anticipate that
further expansion will be required to address potential growth in our customer
base and market opportunities. This expansion has placed, and future expansion
is expected to place, a significant strain on our management, technical,
operational, administrative and financial resources. We have recently hired new
employees, including a number of key managerial and operations personnel, who
have not yet been fully integrated into our operations.

     Our current and planned expansion of personnel, systems, procedures and
controls may be inadequate to support our future operations. We may be unable to
attract, retain, motivate and manage required personnel, including finance,
administrative and operations staff, or to successfully identify, manage and
exploit existing and potential market opportunities because of inadequate
staffing. We may also be unable to manage further growth in our relationships
with our distributors and other third parties. If we are unable to manage growth
effectively, our business, financial condition and results of operations could
be harmed.

IF WE ARE UNABLE TO EXPAND OUR DIRECT SALES OPERATION AND OUR DISTRIBUTION
CHANNELS OR SUCCESSFULLY MANAGE OUR EXPANDED SALES ORGANIZATION, OUR ABILITY TO
INCREASE OUR REVENUES WILL BE HARMED.

     Historically, we have relied primarily on our direct sales organization to
sell our systems domestically and on a limited number of distributors to sell
our systems internationally. We may not be able to successfully expand our
direct sales organization and the cost of any expansion may exceed the revenue
generated. To the extent that we are successful in expanding our direct sales
organization, we cannot assure you that we will be able to compete successfully
against the significantly larger and well-funded sales and marketing operations
of many of our current or potential competitors. In addition, if we fail to
develop relationships with significant distributors, or if these distributors
are not successful in their sales or marketing efforts, sales of our systems may
decrease and our business would be significantly harmed.

OUR DISTRIBUTORS MAY NOT GIVE PRIORITY TO OUR SYSTEMS WHICH MIGHT RESULT IN
LOWER PRODUCT SALES.

     We expect that our distributors will also sell competing systems. These
distributors may not continue, or may not give a high priority to, marketing and
supporting our systems. This and other channel conflicts could result in
diminished sales through the indirect channel and harm our operating results. If
our distributors do not prioritize selling our systems, our business and results
of operations could be harmed.

OUR OPERATING RESULTS WILL SUFFER IF SALES DO NOT INCREASE AS ANTICIPATED TO
SUPPORT THE EXPENSES OF EXPANDING OUR BUSINESS.

     Because our operating expenses for personnel, new system development and
inventory continue to increase, we must continue to generate increased sales to
offset these increased expenses. We have limited ability to reduce expenses
quickly in response to any revenue shortfall. In response to anticipated long
lead times to obtain inventory and materials from our contract manufacturers and
suppliers, we have in the past and may continue to need to order in advance of
anticipated customer demand. Advance ordering has and may continue to result in
higher inventory levels. To sell this increasing inventory, we have depended on
and will continue to depend on an increase in customer demand. Any significant
shortfall in customer demand would harm our quarterly and annual operating
results.

CONTROL BY OUR EXISTING STOCKHOLDERS COULD DISCOURAGE POTENTIAL ACQUISITIONS OF
OUR BUSINESS THAT OTHER STOCKHOLDERS MAY CONSIDER FAVORABLE.

     Upon completion of this offering, our executive officers, directors and 5%
or greater stockholders and their affiliates will own ______ shares or
approximately ______ % of the outstanding shares of common stock. Acting
together, these stockholders would be able to control all matters requiring
approval by stockholders, including the election of directors. This
concentration of ownership could have the effect of delaying or preventing a
change in our control or otherwise discouraging a potential acquirer from
attempting to obtain control of us, which in turn could harm the market price of
our common stock or prevent our stockholders from realizing a premium over the
market price for their shares of common stock.


                                       13
<PAGE>

OUR CERTIFICATE OF INCORPORATION AND BYLAWS MAY DISCOURAGE POTENTIAL
ACQUISITIONS OF OUR BUSINESS BY THIRD PARTIES THAT STOCKHOLDERS MAY CONSIDER
FAVORABLE.

     Some provisions of our certificate of incorporation and bylaws and of
Delaware law may discourage, delay or prevent a merger or acquisition that
stockholders may consider favorable. This may reduce the market price of our
common stock. A summary of these provisions is included in "Description of
Capital Stock--Anti-Takeover Effects of Provisions of the Certificate of
Incorporation, Bylaws and Delaware Law."

OUR HEADQUARTERS AND MANY OF OUR CONTRACT MANUFACTURERS ARE LOCATED IN NORTHERN
CALIFORNIA WHERE NATURAL DISASTERS MAY OCCUR.

     Currently, our corporate headquarters and many of our contract
manufacturers are located in Northern California. Northern California
historically has been vulnerable to natural disasters such as earthquakes, fires
and floods, which at times have disrupted the local economy and posed physical
risks to our and our manufacturers' property. We presently do not have redundant
site capacity in the event of a natural disaster. In the event of a natural
disaster, our business would suffer.

WE MAY HAVE LIABILITY FOR OPTIONS WE GRANTED AND STOCK WE ISSUED IN VIOLATION OF
SECURITIES LAWS.

     We granted stock options to various individuals between June 1997 and April
2000 under our 1997 Stock Option/Stock Issuance Plan. A substantial portion of
the shares of our common stock that are subject to the grants were not qualified
or exempted under applicable state securities laws and therefore the options may
have been granted in violation of these laws. As a result, we may have potential
liability under state securities laws to the individuals and entities to whom
the options were granted or who purchase shares of our common stock upon the
exercise of those options. Any liability to the option holders will be in the
form of a rescission offer to them in which they will have the opportunity to
rescind their option grants in return for a cash payment from us based upon a
percentage of the exercise price payable under their options, and any liability
to individuals or entities who actually purchase shares under the options will
be in the form of an offer from us to repurchase those shares for a cash amount
equal to the exercise price paid for the shares, together with interest due to
both the option holders and the stock purchasers who accept the offers which is
to accrue from the date of the option grant and the date of the option exercise,
respectively. We are currently analyzing this matter and cannot, at this time,
ascertain the extent of our potential liability, if any. Nevertheless, the
exercise prices in effect for the options granted prior to this offering range
from $0.05 to $5.00 per share, and accordingly, we do not believe that our
potential liability would exceed $275,000 in the aggregate for any potential
liability associated with those option grants. We do not anticipate that many of
our current employees, who, as of December 31, 1999, held options for 1,706,047
shares, will accept such a rescission offer for their option grants, because the
exercise price of those options is substantially below the price per share in
this offering. In addition, we will apply to the satisfaction of any liability
we determine we have to any option holders who have actually exercised their
options whatever portion we retain of the monies paid to us in connection with
those option exercises.

                         RISKS RELATING TO OUR INDUSTRY

SOME OF OUR SYSTEMS HAVE LONG SALES CYCLES, WHICH COULD CAUSE OUR RESULTS OF
OPERATIONS AND STOCK PRICE TO FLUCTUATE.

     Some of our systems have sales cycles that are long and unpredictable. As a
result, our revenues may fluctuate from quarter to quarter and fail to
correspond with our expenses. This would cause our operating results and stock
price to fluctuate. Our customers typically perform numerous tests and
extensively evaluate our systems before incorporating them into networks. The
time required for testing, evaluation, design and integration of our systems
into a customer's network typically ranges from two to six weeks. If a customer
decides to supply commercial service using our systems, it can take an
additional six to twelve months before it can commence installation of our
products. Some additional factors that affect the length of our sales cycle
include:

     o    acquisition of roof rights;

     o    installation and planning of network infrastructure;

     o    complexity of a given network;

     o    scope of a given project;

     o    availability of radio frequency; and

     o    regulatory issues.

     In addition, the delays inherent in our sales cycle raise additional risks
of customer decisions to cancel or change their product plans. Our business
could be harmed if a significant customer reduces or delays orders or chooses
not to install networks incorporating our systems.

INTENSE COMPETITION IN THE MARKET FOR COMMUNICATIONS EQUIPMENT COULD PREVENT US
FROM INCREASING OR SUSTAINING REVENUES OR ACHIEVING OR SUSTAINING PROFITABILITY.

     The market for high-speed, wireless, point-to-point and point-to-multipoint
communications equipment is rapidly evolving and highly competitive. Increased
competition is likely to result in price reductions, shorter product life
cycles, reduced gross margins, longer sales cycles and loss of market share, any
of which would harm our business. As a provider of high-speed wireless
communications equipment, we compete with a number of large communications
equipment suppliers in the point-to-multipoint market, including Adaptive
Broadband Corporation, BreezeCOM, Ltd., Gigabit Wireless, Inc., Lucent
Technologies, Inc., Netro Corporation, and Wavtrace Inc., as well as with
smaller start-up companies. We also compete with communications equipment
suppliers, such as BreezeCom, Digital Microwave Corporation, Lucent and P-Com,
Inc., in the point-to-point market. In addition, well-capitalized companies such
as Ericsson, Inc., Motorola, Inc., Nokia Corporation, QUALCOMM Corporation and
Siemens AG are potential entrants into either market. Our broadband wireless
access technology also competes with wired solutions such as cable, DSL, fiber
optic systems and high-speed lines leased from communication service providers,
such as T-1 lines.

     We expect our competitors to continue to improve the performance of their
current systems and to introduce new systems or new technologies that may
supplant or provide lower cost alternatives to our systems. To be competitive,
we must continue to invest significant resources in research and development,
sales and marketing and customer support. We cannot be sure that we will have
sufficient resources to make these investments or that we will be able to make
the technological advances necessary to be competitive. As a result, we may not
be able to compete effectively against our competitors.

WE EXPECT AVERAGE SELLING PRICES OF OUR BROADBAND WIRELESS ACCESS SYSTEMS TO
DECREASE WHICH WOULD REDUCE GROSS MARGINS OR REVENUES, AND, AS A RESULT, WE MUST
CONTINUE TO REDUCE OUR SYSTEM COSTS IN ORDER TO PRICE OUR SYSTEMS COMPETITIVELY.

     The market for broadband wireless access systems is characterized by
declining average selling prices resulting from factors such as increased
competition, the introduction of new products and systems and competitive
pressures from traditional wired broadband network access technologies. We
anticipate that average selling prices will decrease in the future in response
to product and system introductions by competitors, or in response to other
factors, including pricing pressures from significant customers. Additionally,
because lower prices are typically


                                       15
<PAGE>

charged on sales made through indirect channels, increased indirect sales could
adversely affect our average selling prices and result in lower gross margins.
Therefore, we must continue to develop and introduce on a timely basis new
systems that incorporate features that can be sold at higher average selling
prices. Failure to do so would cause our revenues and gross margins to decline,
which would significantly harm our business.

     We may be unable to reduce the cost of our systems sufficiently to enable
us to compete with others. Our cost reduction efforts may not allow us to keep
pace with competitive pricing pressures or lead to improved gross margins. In
order to remain competitive, we must continually reduce the cost of
manufacturing our systems through design and engineering changes. We may not be
successful in redesigning our systems or delivering our systems to market in a
timely manner. We cannot assure you that any redesign will result in sufficient
cost reductions to allow us to reduce the price of our systems to remain
competitive or improve our gross margin.

OUR MARKET IS SUBJECT TO RAPID TECHNOLOGICAL CHANGE, AND TO COMPETE EFFECTIVELY,
WE MUST CONTINUALLY INTRODUCE NEW SYSTEMS THAT ACHIEVE MARKET ACCEPTANCE.

     The market for broadband wireless access systems is characterized by
rapidly changing technology and evolving industry standards. Our success will
depend to a substantial degree on our ability to develop and introduce in a
timely and cost-effective manner enhancements to our existing systems. Our
success also depends upon introducing new products that meet changing customer
requirements and evolving industry standards. Our technology or our systems may
become obsolete upon the introduction of alternative technologies by larger
competitors with more extensive research and development capabilities. If we
fail to introduce, and achieve market acceptance of, new systems and products in
a timely manner, our business, operating results and financial condition will be
materially harmed.

OUR SUCCESS IS DEPENDENT ON THE CONTINUED DEVELOPMENT OF THE EMERGING BROADBAND
WIRELESS ACCESS MARKET.

     The market for broadband wireless access technology has only recently begun
to develop and is rapidly evolving. Because this market is new, it is difficult
to predict its potential size or future growth rate. Our success in generating
revenue in this emerging market will depend, among other things, on the growth
of this market. If the market for broadband wireless access technology fails to
develop or develops more slowly than expected, or if our systems do not achieve
widespread market acceptance in this market, our business would be significantly
harmed.

WE WILL FACE CHALLENGES TO OUR BUSINESS IF OUR TARGET MARKET ADOPTS ALTERNATE
STANDARDS FOR WIRELESS TRANSMISSION, OR IF OUR SYSTEMS FAIL TO COMPLY WITH
EVOLVING INDUSTRY STANDARDS AND GOVERNMENT REGULATIONS.

     Broadband wireless access technology is extremely complex, and products
must adhere to a continually changing set of standards and compliance
requirements. Currently, our systems meet the present protocol standards for
data transmission. The protocol definitions for data transmission, however, are
established by standards organizations over which we have no direct influence.
We have invested substantial amounts of engineering resources into developing
interfaces that are compliant with these standards. Should these organizations
change the standards for data transmission or its associated technology, or if
these organizations introduce new and substantially different standards for data
transmission, we may not be able to introduce systems in a timely manner that
meet these new and evolving standards. If we fail to introduce systems that meet
new and evolving data transmission standards, our business would be
significantly harmed.

A MAJORITY OF SERVICE PROVIDERS THAT USE WIRELESS TECHNOLOGIES ARE EMERGING
COMPANIES WITH UNPROVEN BUSINESS MODELS.

     Many of our customers are service providers that are using wireless
technologies to attract and retain new end-user customers. Many of these service
providers are emerging companies with a limited degree of success in the
broadband wireless access industry. The broadband wireless access market is
intensely competitive, and the service providers typically are forced to reduce
the monthly access charges they impose upon their subscribers in order to
attract and retain additional subscribers. The reduction in monthly access
charges reduces the amount of capital available for service providers to invest
in additional wireless infrastructure. These service providers may therefore
become under-capitalized and may not be able to remain in business for a
substantial period of time. The failure or loss of these service providers as
customers would significantly harm our business.


                                       16
<PAGE>

WE NEED TO DEVELOP SYSTEMS THAT WORK IN A VARIETY OF DIFFERENT COUNTRIES WHICH
HAVE DIFFERENT REGULATORY REQUIREMENTS.

     Our systems are subject to the rules and regulations of the governing
bodies for radio transmission and telecommunications in the countries in which
our products are designed to operate. In the United States, the Federal
Communications Commission, or FCC, determines the rules, regulations and
procedures under which products must be certified. The FCC is also responsible
for establishing which frequency bands can be allocated for use by systems that
are intended to provide broadband wireless access and networking systems. In the
United States, operation of unlicensed radio communications equipment is subject
to the conditions that no harmful interference is caused to authorized users of
the band, and that interference, including interference that may cause undesired
operation, must be accepted from all other users of the band. This includes
other unlicensed operators, authorized operators such as amateur licensees,
Industrial, Scientific and Medical equipment, and U.S. Government operations.
Unlicensed operators that cause harmful interference to authorized users, or
that exceed permitted radio frequency emission levels, may be required to cease
operations until the condition causing the harmful interference or excessive
emissions has been corrected. If any of our systems interfere with these
authorized operators, or if any authorized operators cause interference
resulting in undesired operation, we may be prevented from operating these
systems and our business may be harmed.

     Outside of the United States, our products are subject to the rules and
regulations as set forth by the governing bodies for radio transmission and
telecommunications of the host country. In most cases, the rules and regulations
differ substantially between countries, and radio design is therefore
significantly affected. We are therefore at great risk in entering new markets
when we do not presently have radio technology designed to meet the local rules
and regulations.

THERE MAY BE POTENTIAL HEALTH AND SAFETY RISKS RELATED TO OUR BROADBAND WIRELESS
ACCESS SYSTEMS WHICH COULD NEGATIVELY AFFECT SALES.

     There has been recent public concern regarding the potential health and
safety risks of electromagnetic emissions. Our broadband wireless access systems
intentionally emit electromagnetic radiation. If safety or health issues do
arise, our system sales could decline or cease. Even if safety concerns
ultimately prove to be without merit, negative publicity could materially harm
our ability to market our systems. In addition, we may be subject to litigation,
with or without basis in fact, alleging that we are responsible for injuries or
illnesses relating to this radiation. If this litigation were not resolved in
our favor, our results of operation could be materially harmed. Moreover, even
if the litigation were resolved in our favor, the costs of litigating or of
settlement could be significant.

BECAUSE OF INTENSE COMPETITION, WE MAY NOT BE ABLE TO RECRUIT OR RETAIN
QUALIFIED PERSONNEL.

     Our growth in operations has placed significant demands on our management,
engineering staff and facilities. Continued growth will require us to hire more
engineering, manufacturing, sales and administrative personnel. We may not be
able to attract and retain the necessary qualified personnel to accomplish our
business objectives and we may experience constraints that could harm our
ability to satisfy customer demand in a timely fashion or to support our
customers and operations. We have at times experienced, and continue to
experience, difficulty in recruiting qualified personnel. Recruiting qualified
personnel is an intensely competitive and time-consuming process. We will need
to train new sales and marketing personnel before they achieve full
productivity. The design and installation of broadband wireless access
technology can be complex. Accordingly, we need highly trained professional
services and customer support personnel to service our customers. We cannot be
certain that we will be able to successfully attract and retain additional
qualified personnel. In addition, recently hired employees may not successfully
integrate into our management team. The inability to attract and retain
qualified personnel or to assimilate them into our business could significantly
harm our business.

WE MAY BE HARMED BY DELAYED YEAR 2000 PROBLEMS.

     Although the date is now past January 1, 2000, and we have not experienced
immediate harm from the transition to the Year 2000, we cannot provide assurance
that we or our suppliers and customers have not been affected in a manner that
is not yet apparent. In addition, some computer programs that were date
sensitive to the


                                       17
<PAGE>

Year 2000 may not have been programmed to process the Year 2000 as a leap year,
and any negative consequential effects remain unknown. In particular, we are
subject to:

     o    costs associated with the failure of our products to be year 2000
          compliant, including potential warranty or other claims from our
          customers, which may result in significant expenses to us;

     o    business shutdowns or slowdowns as a result of a failure of the
          internal management systems we use to run our business, which could
          disrupt our business operations;

     o    interruption of system or component supplies, or a reduction in
          product quality, as a result of the failure of systems used by our
          suppliers; and

     o    reductions or deferrals in sales activities as a result of year 2000
          compliance issues of our distributors and system integrators.

As a result, we will continue to monitor our Year 2000 compliance and the Year
2000 compliance of our suppliers and customers. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Year 2000
Compliance."


                         RISKS RELATING TO THIS OFFERING

THERE IS NO PRIOR PUBLIC MARKET FOR OUR COMMON STOCK AND OUR SHARE PRICE MAY
DECLINE AFTER THIS OFFERING.

     There has not been a public market for our common stock. We cannot predict
the extent to which investor interest in our common stock will lead to the
development of a trading market or how liquid that market might become. The
initial public offering price for the shares was determined by negotiations
between us and the representatives of our underwriters and may not be indicative
of the prices that will prevail in the trading market. The market price of our
common stock could be subject to wide fluctuations in response to a number of
risk factors, most of which are outside our control. Some of these include:

     o    quarter-to-quarter variations in our operating results;

     o    our announcements about the performance of our products and our
          competitors' announcements about performance of their products;

     o    changes in earnings estimates by, or failure to meet the expectations
          of, analysts;

     o    government regulatory action, particularly affecting licensed radio
          frequency bands;

     o    increased price competition;

     o    developments or disputes concerning intellectual property rights;

     o    general conditions in the computer and telecommunications industries
          in general, and the broadband access industry, in particular;

     o    economic conditions in international markets in which we do business;

     o    the ability of our contract manufacturers and sole-source suppliers to
          fill our orders on a timely basis; and

     o    our customers' purchasing decisions and the timing of those decisions.

     Furthermore, stock markets have experienced extreme price and volume
fluctuations that have affected and continue to affect the market prices of
equity securities of many technology companies. These fluctuations often have
been unrelated or disproportionate to the historical performance of those
companies. Market fluctuations as well as general economic, political and market
conditions such as recessions, interest rate changes or currency or exchange
rate fluctuations, may negatively impact the market price of our common stock.

SUBSTANTIAL NUMBERS OF SHARES OF OUR COMMON STOCK WILL BECOME AVAILABLE FOR SALE
IN THE PUBLIC MARKET SIMULTANEOUSLY, WHICH COULD CAUSE THE MARKET PRICE OF OUR
STOCK TO DECLINE.

     Sales of substantial amounts of common stock in the public market following
this offering, or the appearance that a large number of shares is available for
sale, could cause the market price of our common stock to decline. In


                                       18
<PAGE>

addition to the adverse effect a price decline could have on holders of common
stock, that decline would likely impede our ability to raise capital through the
issuance of additional shares of common stock or other equity securities. Upon
completion of this offering, we will have outstanding ____________ shares of
common stock, based upon shares outstanding as of December 31, 1999, assuming no
exercise of the underwriters' over-allotment option and no exercise of
outstanding options after December 31, 1999. Of these shares, the ___________
shares sold in the offering will be freely tradable. Upon the expiration of
lock-up agreements between our stockholders and us or Salomon Smith Barney Inc.,
another ____________ shares of common stock will become eligible for sale
simultaneously 180 days after the date of the final prospectus relating to this
offering. Salomon Smith Barney may, in its sole discretion and at any time,
release all or any portion of the securities subject to lock-up agreements. The
remaining ___________ shares will be restricted securities that have been held
for less than one year and are not yet salable under Rule 144. See "Shares
Eligible for Future Sale."

     After this offering, if certain conditions are met, the holders of
approximately 20,509,837 shares of common stock and the holders of warrants to
purchase up to approximately 552,500 shares of common stock will be entitled to
require us to register their shares under the Securities Act. These shareholders
and holders of an additional 68,662 shares of our common stock issuable upon the
exercise of outstanding warrants also have the right to participate in any
registration of our shares which we undertake on our own. If these shareholders
exercise their registration rights, a large number of our shares may be
registered and sold in the public market. This could adversely affect the
trading price for our shares. If we attempted to raise money through a
registration and sale of our stock and these shareholders forced us to allow
them to participate in the registration, our ability to raise the amount of
money we need to execute our business plan could be adversely affected. See
"Description of Capital Stock--Registration Rights."

YOU WILL NOT HAVE CONTROL OVER MANAGEMENT'S USE OF THE PROCEEDS FROM THIS
OFFERING AND THE PROCEEDS MAY NOT BE APPROPRIATELY USED.

     We expect to use the net proceeds from the offering for general corporate
purposes, including working capital, product development and capital
expenditures. $2.5 million of the proceeds will be paid to TRW in connection
with the license of the STARPORT technology. We may use a portion of the
proceeds to invest in complementary businesses or products or to obtain the
right to use complementary technologies. However, we will have broad discretion
in how we use the net proceeds from the offering, and we may ultimately decide
to use the proceeds for purposes other than the above and may not use proceeds
for any one or more of the above purposes. You will not have the opportunity to
evaluate the economic, financial or other information on which we base our
decisions on how to use the net proceeds or to approve these decisions. If our
management uses poor judgment in spending our proceeds, our business will be
harmed.

                           FORWARD-LOOKING STATEMENTS

       This prospectus contains forward-looking statements which involve risks
and uncertainties. These forward-looking statements are not historical facts but
rather are based on current expectations, estimates and projections about our
industry, our beliefs and assumptions. We use words such as "anticipates,"
"expects," "intends," "plans," "believes," "seeks," "estimates" and variations
of these words and similar expressions to identify forward-looking statements.
These statements are not guarantees of future performance and are subject to
certain risks, uncertainties and other factors, some of which are beyond our
control, are difficult to predict and could cause actual results to differ
materially from those expressed or forecasted in the forward-looking statements.
These risks and uncertainties include those described in "Risk Factors" and
elsewhere in this prospectus. You should not place undue reliance on these
forward-looking statements, which reflect our management's view only as of the
date of this prospectus. We undertake no obligation to update these statements
or publicly release the result of any revision to the forward-looking statements
that we may make to reflect events or circumstances after the date of this
prospectus or to reflect the occurrence of unanticipated events.

                                 USE OF PROCEEDS

       Our net proceeds from the sale and issuance of the ______________
shares of common stock offered are estimated to be $______million at an assumed
initial public offering price of $ _______ per share after deducting estimated
underwriting discounts and commissions and estimated offering expenses. If the
underwriters' over-allotment option is exercised in full, our estimated net
proceeds will be $ ________ million. We are conducting this offering primarily
to increase our equity capital, to create a public market for our common stock
and to facilitate our future access to public equity markets. We intend to use
the net proceeds for general corporate purposes, including working capital,
product development and capital expenditures. $2.5 million of the proceeds will
be paid to TRW, Inc. upon completion of this offering in connection with the
license of the STARPORT technology. In addition, we may use a portion of the net
proceeds to acquire or invest in complementary businesses or products or to
obtain the right to use complementary technologies. We currently have no
agreements or commitments with respect to any acquisition or investment, and we
are not involved in any negotiations with respect to any similar transaction.
Pending these uses, we will invest the net proceeds of the offering in
short-term, interest-bearing investment-grade securities. See "Risk Factors--You
will not have control over management's use of the proceeds from this offering"
and "Certain Transactions--Strategic Relationship with TRW."

                                 DIVIDEND POLICY

       We have never declared or paid dividends on our capital stock. We intend
to retain any future earnings to finance the operation and expansion of our
business and do not anticipate declaring or paying cash dividends in the
foreseeable future. Payments of future dividends, if any, will be at the
discretion of our board of directors after taking into account various factors,
including our financial condition, operating results, current and anticipated
cash needs and plans for expansion. In addition, our loan agreement with Silicon
Valley Bank prohibits the payment or declaration of dividends without its prior
written consent. Consequently, stockholders will need to sell shares of common
stock in order to realize a return on their investment, if any.

                                    DILUTION

       Dilution is the amount by which the initial public offering price paid by
the purchasers of shares of common stock in the offering exceeds the net
tangible book value per share of common stock after the offering. The pro forma
net tangible book value per share of common stock is determined by subtracting
our total liabilities from the total book value of our tangible assets and
dividing the difference by the number of shares of common stock deemed to be
outstanding on the date of which such book value is determined.

     Our pro forma net tangible book value at December 31, 1999, was
approximately $21.8 million, or $0.69 per share. After giving effect to the sale
of the shares of common stock offered by us at the assumed initial public
offering price of $ __________ per share, and after deducting underwriting
discounts and estimated offering expense, our pro forma net tangible book value
at December 31, 1999, would have been $ __________ million, or $      per share.
This represents an immediate increase in net tangible book value of $ _________
per share to existing stockholders and an immediate dilution of $ _________ per
share to new investors purchasing shares of our common stock in this offering.
The following table illustrates this dilution:

              2000 Employee Stock Purchase Plan.

       To the extent that any of these options or warrants are exercised, there
could be further dilution to new investors. For additional information regarding
these shares, see "Capitalization," "Executive Compensation and other

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

       THE FOLLOWING DISCUSSION OF OUR FINANCIAL CONDITION AND RESULTS OF
OPERATIONS SHOULD BE READ IN CONJUNCTION WITH THE FINANCIAL STATEMENTS AND THE
RELATED NOTES TO THOSE STATEMENTS INCLUDED ELSEWHERE IN THIS PROSPECTUS. THIS
DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. THESE FORWARD-LOOKING STATEMENTS INCLUDE, AMONG OTHERS, THOSE
STATEMENTS INCLUDING THE WORDS "EXPECTS," "ANTICIPATES," "INTENDS," "BELIEVES"
AND SIMILAR LANGUAGE. OUR ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE
ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF VARIOUS FACTORS,
SUCH AS THOSE SET FORTH UNDER "RISK FACTORS" AND ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

       We are a global provider of broadband wireless access solutions that
enable Internet and communication service providers, telephone operating
companies and private network operators to deliver voice and high-speed data
services to their customers.

       We were incorporated in California on May 7, 1997 to develop advanced
wireless access communications systems for networking and telephony
interconnection solutions. In 1997, under a master distributor agreement with
Innova Corporation, later acquired by Digital Microwave Corporation, we
introduced the ADR series, a family of high capacity digital radios. All of our
1997 revenues and approximately 54% of our 1998 revenues and 25% of our 1999
revenues were derived from this distributor agreement. We subsequently renamed
the ADR series as the WAVENET TRANSPORT DX.

       In 1998, we released our ACCESS series of point-to-point spread spectrum
digital radios under a License and Technology Transfer and Manufacturing
Agreement with Wi-LAN, Inc. We also introduced the N2-ACCESS series, a
point-to-point digital radio to offer a smaller, cost-competitive package for
cellular and personal communication services, or PCS, networks. We subsequently
renamed the N2-ACCESS series as the WAVENET LINK series.

       On August 26, 1998 we acquired Multipoint Networks, Inc., a California
corporation. The acquisition was accounted for by the purchase method and is
included in our operating results from the date of acquisition forward.
Multipoint developed, manufactured and marketed point-to-point and
point-to-multipoint digital wireless radios for customers connecting lottery
terminals, bank automated teller machines, and point-of-service networks. Just
prior to the acquisition, Multipoint Networks, Inc. designed the WAVENET IP
2400. Initial shipments of the WAVENET IP 2400 were made in early 1998. In May
1999, we introduced the WAVENET IP 2458. We subsequently renamed the WAVENET IP
series as the WAVENET ACCESS series.

       We market our products through our direct sales force, complemented by
indirect sales channels consisting of agents, distributors, resellers, system
integrators and value-added resellers. Sales to international markets during
1999 were $17.7 million, or 83% of total sales and $10.2 million, or 91% of
total sales, for 1998. All of our international sales are denominated in U.S.
dollars.

       REVENUE. Revenue consists of product and service revenue. Product revenue
is recognized when all of the following occur:

       o      the product has been shipped;

       o      title and risk of loss have passed to the customer;

       o      we have the right to invoice the customer and collection of
              receivable is probable; and

       o      all pre-sales obligations have been fulfilled.

       Service revenue is recognized when service obligations have been
completed. Trial sales made directly to the end users are not recognized as
revenue until the trial has been completed and the product has been accepted.

       COST OF REVENUE. Cost of revenue consists of materials, manufacturing
labor and overhead, outsourced contract manufacturing costs and cost of
acquiring finished products from original equipment manufacturers.

       RESEARCH AND DEVELOPMENT. Research and development expenses consist
primarily of salaries and related personnel expenses, contract engineering
services, consulting fees, software development tools, and prototype


                                       26
<PAGE>


expenses related to the design, development, testing and enhancement of our
products. All research and development costs are expensed as incurred until
technological feasibility of the product is established. After technological
feasibility is established, material development costs are capitalized. To date,
the period between technological feasibility and general release of the product
has been short and development costs have been insignificant. Accordingly, the
Company has expensed all development costs. We expect these expenses to increase
significantly in the future as we seek to develop new products and enhance
existing products. A significant portion of the increase in research and
development expenses is expected to be in the contracting of independent and
third party research and development vendors in connection with the development
of our STARPORT system. See "Certain Transactions--Strategic Relationship with
TRW."

       SALES AND MARKETING. Sales and marketing expenses consist primarily of
salaries, commissions and related personnel expenses of our sales agents and
direct sales force. In addition, sales and marketing expenses consist of travel,
trade show, advertising, promotional and public relations expenses. Also
included are costs related to testing and certifying our products to meet
regulatory requirements in various foreign countries. We intend to pursue sales
and marketing campaigns aggressively and therefore expect these expenses to
increase in the future.

       GENERAL AND ADMINISTRATIVE. General and administrative expenses consist
primarily of salaries and related personnel expenses for executive, accounting
and administrative personnel, as well as accounting and legal fees and other
general corporate expenses. As we add personnel and incur additional costs
related to the growth of our business and operating as a public company, we
expect that general and administrative expenses will also increase. We allocate
the total costs for information services and facilities to each functional area
that uses the information services and facilities based on our relative
headcount. These allocated costs include medical insurance premiums,
communication charges and rent and other facility-related costs.

       AMORTIZATION OF DEFERRED STOCK COMPENSATION. In connection with granting
stock options to our employees, directors and consultants, we recorded deferred
stock-based compensation totaling approximately $10.3 million through December
31, 1999. This amount represents the total difference between the exercise
prices of stock options and the deemed fair market value of the common stock for
accounting purposes on the date these stock options were granted or other
measurement dates. This amount is included as a component of stockholders'
equity and is being amortized on an accelerated basis over the vesting period of
the options, in accordance with FASB Interpretation No. 28. We have recorded
stock-based compensation expense of $0.6 million during the year ended December
31, 1998, and approximately $4.3 million in 1999, leaving $5.4 million to be
amortized in future periods. Of this amount, $3.7 million will be amortized in
2000, $1.1 million will be amortized in 2001, $0.5 million will be amortized in
2002 and $0.1 million will be amortized in 2003.

       INTEREST EXPENSE (INCOME), NET. Interest expense consists primarily of
interest expense paid on bank borrowings, short-term promissory notes from
investors and the $1.0 million convertible note due on September 1, 2004.
Interest income consists of interest earned on excess cash.

       INCOME TAXES. We have incurred net losses in each quarter since our
inception. As of December 31, 1999, we had an accumulated deficit of $24.8
million. Our net losses resulted from significantly higher manufacturing,
marketing, selling, service and research and development expenditures relative
to our sales levels. We expect to continue experiencing significant increases in
operating expenses, particularly in research and development and sales and
marketing. As a result, we expect to incur additional losses and continued
negative cash flow from operations for the foreseeable future.

       We have not made a provision for federal or California state income taxes
for any period because we have incurred operating losses since inception. As of
December 31, 1999, we had approximately $30.0 million of net loss carryforwards
for federal income tax purposes and approximately $17.0 million of net loss
carryforwards for California state income tax purposes. Utilization of the net
operating loss carryforwards is subject to our ability to generate future
profits and, in addition, may be subject to annual limitations due to an
ownership change as defined in Section 382 of the Internal Revenue Code.

</TABLE>

COMPARISON OF PERIOD FROM INCEPTION TO DECEMBER 31, 1997 AND YEARS ENDED
DECEMBER 31, 1998 AND 1999

       REVENUE. Total revenue increased from $0.2 million from inception through
December 31, 1997 to $11.2 million in 1998 and $21.3 million in 1999. The
increase in revenue in 1998 reflected the sale of our WAVENET TRANSPORT DX
system to a single large customer, the introduction of our WAVENET LINK series
point-to-point radios in September 1998 and the inclusion of revenue of
Multipoint Networks, Inc. from the date of acquisition on August 26, 1998. The
increase in revenue in 1999 was attributable to higher sales resulting from the
introduction of the WAVENET ACCESS 2458 and the WAVENET LINK series.

       COST OF REVENUE. Cost of revenues from inception through December 31,
1997 represented mainly manufacturing overhead and the cost of equipment that we
resold. Cost of revenue increased from $0.4 million in 1997 to $9.1 million in
1998 and $15.8 million in 1999, primarily due to the related increase in
revenue. As a percentage of revenue, cost of revenue decreased from 209.7% to
81.4% and 74.2% during the same period, primarily due to a change in the mix of
products sold, the introduction of our WAVENET ACCESS 2458 and WAVENET LINK
families of systems and the distribution of manufacturing costs over a greater
number of units sold. Cost of revenue in 1999 included a provision of
approximately $1.5 million for inventory obsolescence related to the earlier
legacy products acquired from Multipoint Networks, Inc.

       RESEARCH AND DEVELOPMENT. Research and development expenses increased
from $0.7 million from inception through December 31, 1997 to $2.3 million in
1998 and $3.2 million in 1999. The increases in research and development
expenses were primarily attributable to the addition of engineering personnel
and associated support required to expand and enhance our product lines.
Research and development as a percentage of total revenues decreased from 352.8%
in 1997 to 20.8% in 1998 and 15.1% in 1999. We expect our research and
development expenses to increase significantly, both in terms of absolute dollar
amount and as a percentage of total revenue, due to the anticipated increase in
contract engineering expenses and the increase in senior engineering staff to
support our new development projects, including our STARPORT system.


                                       28
<PAGE>


       SALES AND MARKETING. Sales and marketing expenses increased from $0.9
million from inception through December 31, 1997 to $3.8 million in 1998 and
$7.4 million in 1999. The increase in sales and marketing was related to the
expansion of our sales and marketing organization, trade show expenses and the
increase in commission expenses resulting from higher revenue. Sales and
marketing expense as a percentage of total revenue decreased from 449.3% in 1997
to 34.1% in 1998 and increased to 35.0% in 1999. We expect to continue
increasing our marketing and branding efforts and to recruit additional sales
personnel. Accordingly, we anticipate that sales and marketing expenses will
increase in absolute dollars and will vary as a percentage of total revenue from
year to year.

       GENERAL AND ADMINISTRATIVE. General and administrative expenses increased
from $0.3 million from inception through December 31, 1997 to $1.3 million in
1998 and $2.7 million in 1999 due primarily to increases in salaries and legal,
accounting and consulting expenses. Also included in general and administrative
expenses for 1999 was a one-time building lease termination charge of $0.2
million. We also made a provision for approximately $1.0 million for potential
bad debts in 1999. General and administrative expenses as a percentage of total
revenue decreased from 128.7% in 1997 to 11.8% in 1998 and increased to 12.6% in
1999. We expect that general and administrative expenses will increase in
absolute dollars as we add personnel and incur additional costs relating to the
anticipated growth of our business and our operation as a public company.
However, we expect that these expenses will vary as a percentage of total
revenues from year to year.

       IN-PROCESS RESEARCH AND DEVELOPMENT COSTS ACQUIRED. In-process research
and development of $0.8 million was fully expensed in 1998 upon acquisition as a
result of our determination that the acquired technology had not yet achieved
technological feasibility and that the technology did not have an alternative
future use. The in-process research and development related to Multipoint's
WAVENET ACCESS technology. The valuation of the in-process research and
development was based upon the present value of forecasted operating cash flows
that were expected to be generated from the technology. The valuation also took
into account that the technology was approximately 85% complete as of the
acquisition date.

       AMORTIZATION OF INTANGIBLES. All recorded intangible assets relate to the
acquisition of Multipoint Networks, Inc. Amortization expense associated with
intangible assets was $0.4 million in 1998 and $1.1 million in 1999. As of
December 31, 1999, the remaining balance to be amortized by the end of 2003 was
$3.1 million.

       IMPAIRMENT OF AN INTANGIBLE ASSET. In 1997, we entered into a License and
Technology Transfer and Manufacturing Agreement with Wi-LAN, Inc. Under this
license agreement, Wi-LAN agreed to license and transfer technology to us in
exchange for 3,000,000 shares of our Series A Preferred Stock, valued at $0.50
per share. An asset worth $1.5 million was recorded for the licensed and
transferred technology. In 1997 we determined that the licensed and transferred
technology was not applicable to our needs. As such, we recorded an impairment
charge of $1.5 million related to this acquired technology. On June 3, 1998 the
license agreement was replaced by a new license agreement and a manufacturing
agreement. In February 2000, we terminated the manufacturing agreement due to a
discontinuance of the product line.

       AMORTIZATION OF DEFERRED STOCK COMPENSATION. Amortization of deferred
stock compensation increased from $0.1 million from inception through December
31, 1997 to $0.6 million in 1998 and $4.3 million in 1999. As of December 31,
1999, the remaining balance to be amortized by the end of 2003 was $5.4 million.
Of this amount, $3.7 million will be amortized in 2000, $1.1 million will be
amortized in 2001, $0.5 million will be amortized in 2002 and $0.1 million will
be amortized in 2003.

       INTEREST EXPENSE (INCOME), NET. Interest expense (income), net changed
from interest income of $14,000 from inception through December 31, 1997 to
interest expense of $0.3 million in 1998 and $0.4 million in 1999 reflecting
increases in various bridge financings from investors as well as utilization of
bank credit facilities.

</TABLE>

       Revenue for the third quarter of 1998 was $4.4 million, reflecting an
increase over second quarter 1998 principally related to the inclusion of
Multipoint's revenues commencing on August 26, 1998. Revenue for the first
quarter of 1999 was $6.3 million, significantly higher than 1998 fourth quarter
revenue of $4.0 million primarily due to the resale of WAVENET TRANSPORT DX and
other OEM equipment to a single customer. Revenue for the second quarter of
1999 was $3.5 million. The decrease from the first quarter of 1999 relates to a
decrease in sales of our WAVENET TRANSPORT DX product. The increase in revenue
for the third quarter of 1999 compared to the second quarter of 1999 relates to
increases in sales related to our WAVENET LINK series.

       Our operating results have in the past, and may in the future, fluctuate
on a quarterly and annual basis as a result of various factors. These factors
include, among others:

       o      the size, timing and terms of customer orders;

       o      a decrease in the average selling prices of our systems due to
              competition;

       o      the relatively long sales and development cycles for our systems;

       o      our ability to develop and market new systems;

       o      the ability to obtain regulatory approval of system installation
              in foreign countries;

       o      the ability to reach and maintain required production volumes and
              quality levels for our systems;

       o      general domestic and international economic conditions;

       o      market acceptance of our systems and our customers' services;

       o      introduction of products and systems by our competitors;

       o      our ability to respond to fluctuations in customer order levels;

       o      the timing and provision of returns from our distributors; and

       o      whether our customers buy from a distributor, an OEM or directly
              from us.

Therefore, we believe that period-to-period comparisons of our quarterly
operating results are not necessarily meaningful. You should not rely on them to
predict future performance.

LIQUIDITY AND CAPITAL RESOURCES

       Since inception, we have financed our operations primarily from sales of
our preferred stock totaling $35.2 million and other financing activities,
including a bank credit facility, convertible notes for working capital and
capital leases for the purchase of equipment.

       As of December 31, 1998 and 1999, cash and cash equivalents were $0.4
million and $1.1 million, respectively. The increase in cash and cash
equivalents from 1998 to 1999 is mostly attributable to funds provided by the
sale of equity for $12.7 million, offset by funds used in operations. We have a
$2.0 million bank credit facility secured by substantially all of our assets
which is subject to certain retrictions relating to eligible accounts
receivable. Borrowings under this bank facility accrue interest at the prime
rate plus 2.5%. As of December 31, 1999, we had not drawn against the bank
credit facility and there is no outstanding balance due. Our credit agreement
expires on February 23, 2001. We have recently renegotiated this line to extend
the credit facility to $5.0 million; however, our ability to access the
additional $3.0 million requires us to either consummate an initial public
offering yielding net proceeds of at least $50 million or raise proceeds of
$15.0 million in equity or convertible debentures. We have committed to issue a
warrant to purchase 37,500 shares of our common stock at an exercise


                                       30
<PAGE>

price of $4.00 per share in the event that an initial public offering yielding
net proceeds of at least $50 million is not consummated by May 31, 2000. We have
also issued a convertible promissory note for $1.0 million which matures on
September 1, 2004 and bears interest at a fixed rate of 10% per annum. The note
is convertible at the option of the holder into Series E Preferred Stock at
$3.125 per share. If the note is converted, the holder will receive a warrant to
purchase 32,000 shares of common stock at $0.75 per share.

       Cash used by operating activities was $2.8 million during 1998 and $11.5
million during 1999. The increase in cash used by operating activities from 1998
to 1999 resulted principally from additional net losses incurred, an increase in
accounts receivable of $3.7 million to $5.9 million, a decrease in accounts
payable from $5.1 million to $3.4 million and an increase in inventory from $3.8
million to $4.4 million. The increase in accounts receivable reflects an
increase in sales. The decrease in accounts payable reflects an increase in cash
payments to suppliers as a result of bringing current our accounts payable. The
increase in inventory levels reflects anticipated higher sales levels. These
increases in cash used by operating activities are partially offset by non-cash
charges such as amortization of deferred stock compensation, amortization of
intangibles and depreciation and amortization of fixed assets.

       Cash provided by investing activities in 1998 was $0.1 million. Cash flow
used by investing activities during 1999 was $0.5 million. The decrease in cash
flow from investing activities from 1998 to 1999 was primarily due to purchases
of property and equipment, including computer equipment, furniture,
manufacturing fixtures, testing equipment and leasehold improvements to our new
facility in Santa Clara, California.

       Cash provided by financing activities was $2.8 million in 1998 and $12.8
million in 1999. The increase in cash flow provided by financing activities was
primarily the result of $12.7 million in proceeds from the issuance of common
and preferred stock.

       We have experienced a substantial increase in our expenditures since our
inception consistent with growth in our operations and personnel. We expect to
devote substantial additional resources to our research and development efforts,
our sales, support, and marketing organizations, establishing additional
facilities worldwide and building the infrastructure necessary to support our
current and future products, including our STARPORT system. We believe that the
net proceeds of this offering, together with cash and cash equivalents and funds
available under existing credit facilities will be sufficient to meet our
working capital requirements for at least the next 12 months. We may require
additional funds to support our working capital requirements or for other
purposes and may seek to raise additional funds through public or private equity
financings or from other sources. We have received $15.0 million in capital
commitments from various strategic investors in the event that we do not
complete an initial public offering with gross proceeds of at least $25 million
by May 31, 2000. We cannot assure you that additional financing will be
available on acceptable terms, if at all. In addition, although there are no
present understandings, commitments or agreements with respect to acquisitions
of other businesses, products or technologies, we may, from time to time
evaluate these acquisitions. In order to consummate potential acquisitions, we
may issue additional securities or need additional equity or debt financing and
any financing we undertake may be dilutive to existing investors.

YEAR 2000 COMPLIANCE

       In August 1998, we initiated a Year 2000 compliance program. The program
was directed by our Director of Management Information Systems and included an
intra-company task force with members from each of our principal departments,
including accounting, engineering, manufacturing, sales and marketing. The task
force was charged with identifying areas of potential risk within each
department and making evaluations, modifications, upgrades or replacements, as
appropriate.

       With the change of the new year, we experienced no major problems
associated with Year 2000. The Year 2000 task force continued to monitor the
hardware and software systems used until February 2000. After February, the task
force no longer proactively monitored systems and concluded that we met all Year
2000 compliance standards. As an ongoing effort, we will continue to upgrade
hardware and software systems to cut costs and improve performance.


                                       31
<PAGE>

       Despite our efforts and our experience with Year 2000 so far, we may
discover Year 2000 compliance problems in our systems that will require
substantial revision. In addition, third-party software, hardware and services
incorporated into our information systems may need to be revised or replaced,
all of which could be time-consuming and expensive and result in the following,
any of which could adversely affect our business, financial condition and
results of operations:

       o      delay or loss of revenue;

       o      cancellation of customer contracts;

       o      diversion of development resources;

       o      damage to our reputation;

       o      increased service and warranty costs; and

       o      litigation costs.

       Our failure to fix or replace third-party software, hardware or services
on a timely basis could result in lost revenues, increased operating costs, the
loss of customers and other business interruptions.

RECENT ACCOUNTING PRONOUNCEMENTS

       In June 1998, the FASB issued SFAS No. 133, ACCOUNTING FOR DERIVATIVE
INSTRUMENTS AND HEDGING ACTIVITIES. SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. For a derivative not
designated as a hedging instrument, changes in the fair value of the derivative
are recognized in earnings in the period of change. This statement will be
effective for all annual and interim periods beginning after January 1, 2001.
Management does not believe the adoption of SFAS No. 133 will have a material
effect on the Company's consolidated financial position or results of
operations.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

       We develop products in the United States and sell such products in North,
Central and South America, Africa, Asia and Europe. As a result, our financial
results could be affected by factors such as changes in foreign currency
exchange rates or weak economic conditions in foreign markets. As all sales are
currently made in U.S. dollars, a strengthening of the dollar could make our
products less competitive in foreign markets. We do not use derivative
instruments to hedge our foreign exchange risk. Our interest income is sensitive
to changes in the general level of U.S. interest rates, particularly since the
majority of our investments are in short-term instruments. Due to the nature of
our short-term investments, we have concluded that there is no material market
risk exposure. Therefore, no quantitative tabular disclosures are required.

                                    BUSINESS

OVERVIEW

     We are a global provider of broadband wireless access solutions that enable
Internet and communication service providers, telephone operating companies and
private network operators to deliver voice and high-speed data services to their
customers. We provide a portfolio of wireless systems that connect end-users to
public and private telecommunication networks in domestic and international
markets. Our systems allow an Internet or communication service provider or
enterprise to rapidly install high-speed communications throughout a service
area at a lower cost than a comparable wired network. More than 200 customers in
over 50 countries have purchased and installed our systems.

     Our portfolio of systems allows end-users to transmit voice and data
simultaneously via Internet protocol, or IP, or asynchronous transfer mode, or
ATM, architectures, two leading industry standards for telecommunication
transport. Our broadband wireless access solutions address a wide range of
applications in different markets, including:

     o    enabling Internet service providers to offer direct Internet access;

     o    rapidly installing new networks for communication service providers;

     o    supplementing telephone operating companies' existing wired networks;

     o    establishing communication networks in regions without existing
          infrastructures; and

     o    establishing private corporate networks.

     Our systems are available in a broad range of frequency assignments,
enabling us to address the different regulatory requirements of multiple
geographic markets. We have systems installed and operating in Argentina,
Brazil, Chile, China, Mexico, Panama, the Philippines, Poland and the United
States. In 1999, 83% of our revenues were derived internationally. Our global
service organization provides customer support 24 hours per day, 7 days a week
and offers network design and installation services as part of our wireless
solution.

INDUSTRY BACKGROUND

THE DEMAND FOR HIGH-SPEED NETWORK ACCESS

     As the Internet and public and private communication networks have become
essential for communication, e-commerce and information exchange, the volume of
voice and high-speed data traffic worldwide has increased dramatically. In
addition, user applications, such as electronic mail, telecommuting and
business-to-business exchanges have further increased the amount of network
traffic. This increase in network traffic has resulted in a demand for greater
transmission capacity, or bandwidth, and high-speed, or broadband services to
support it.

     Bandwidth limitations between service providers' central offices and
end-users, often referred to as the last mile bottleneck, have constrained
service providers from delivering broadband services to the end-user. We believe
that traditional dial-up modem technology is insufficient to support the growth
in network traffic and demand for high-speed data transmission. Although wired
access network infrastructures using cable, digital subscriber line, or DSL, and
fiber optic systems can deliver greater bandwidth than that provided by dial-up
modem technology, these systems are not universally available to end-users. This
last mile bottleneck is frustrating a broad base of business, residential and
small office/home office users, many of whom require high-speed access to data.

WIRED SOLUTIONS

     The demand for broadband access continues to accelerate, pressuring service
providers to improve and expand existing wired infrastructures. Wired broadband
access solutions that are intended to address this demand include cable modem
service, DSL and fiber optic technology. Often, these technologies require a
trained installation technician and are characterized by a lengthy
implementation process.


                                       33
<PAGE>

     COAXIAL CABLE MODEM. Coaxial cable modem technology is currently the most
common wired solution for broadband network access. The cable solution is
limited in its effectiveness, however, because:

     o    performance deteriorates as more subscribers are added because the
          users share a common transmission medium;

     o    performance difficulties worsen as users transmit more data because
          transmission capacity has been allocated primarily to receiving data,
          or downstream transmission, and cannot be easily reallocated to
          transmitting data, or upstream transmission;

     o    there are inherent privacy limitations because all users share a
          common link rather than using an individual link; and

     o    the current infrastructure is primarily geared towards residential
          service, and is unavailable to most business customers.

     DSL. DSL service is delivered over existing copper-based wired
infrastructure and is gaining wide acceptance by both residential and business
markets for high-speed Internet access. However, DSL service is limited in its
effectiveness because:

     o    the length and quality of available copper wires limit transmission
          rates;

     o    the condition of many of the copper lines between the subscriber and
          central office prohibits the use of DSL technology; and

     o    federally mandated regulations require service providers who upgrade
          their copper-based infrastructures to offer competing service
          providers access to their upgraded infrastructures. As a result,
          service providers are reluctant to upgrade their infrastructures, and
          copper wire infrastructures are not keeping pace with the increase in
          demand for high-speed Internet access.

     FIBER OPTIC. Fiber optic transmission systems offer far greater
transmission rates than either cable modem or DSL service offerings. Although
many wide-area networks have been upgraded to fiber optic cable, fiber optic
technology is not a cost effective last-mile broadband access solution due to
its high installation cost. Similarly, dedicated leased lines providing high
speed Internet access, such as T-1 lines, also have high installation costs that
deter most business customers from pursuing them.

WIRELESS SOLUTIONS

     Non-movable, or fixed, broadband wireless access technology can solve many
of the problems imposed by wired networks. Broadband wireless technology enables
rapid implementation of high-speed network access in a cost-effective manner
relative to wired networks. We believe that wireless network providers should be
able to gain a greater share of the network access market because, unlike wired
network providers, they are not required by federal law to share their wireless
networks with competing service providers. A broadband wireless network is often
the best option for high-speed communication in remote areas and in many
developing countries due to the lack of an existing wired infrastructure. In
these regions, wireless technologies provide clear advantages over wired
networks, including lower cost, faster installation, greater flexibility and
increased reliability.

     Broadband wireless technologies are classified as either point-to-point or
point-to-multipoint:

         POINT-TO-POINT. Point-to-point wireless technology is used to transport
     data traffic from one location to another, typically in local distribution
     applications. Point-to-point wireless systems can interconnect high-speed
     data networks between buildings or facilities within the same metropolitan
     area. However, implementing a large wireless network based on
     point-to-point technology becomes costly and cumbersome as the number of
     locations increases. As a result, this technology is not practical for
     interconnecting a large number of buildings or facilities.

         POINT-TO-MULTIPOINT. Point-to-multipoint wireless technology is used to
     interconnect a large number of facilities in a relatively small geographic
     area. Point-to-multipoint wireless technology overcomes the limitations of
     point-to-point technology by designating a single radio transceiver as the
     central base station. The base station uses a radio protocol to control and
     manage end-user devices so that data is transmitted and received among
     multiple locations with minimal interference. An area served by a single
     base station is often referred to as a cell. In order to serve a larger
     geographic region and a larger number of facilities, multiple


                                       34
<PAGE>

cells are interconnected using point-to-point technology. As a result,
point-to-multipoint systems are combined with point-to-point technology to
deliver broadband wireless access service to a large geographic area.

     Historically, most broadband wireless manufacturers focused on delivering
either point-to-multipoint or point-to-point systems. Few companies have merged
both technologies to deliver a single broadband wireless access solution for
large geographic areas that meets the needs of business and residential
end-users over the last mile. The absence of a single broadband wireless
solution is magnified internationally, where the lack of wire-based
infrastructure and the prohibitive costs associated with building new wired
infrastructure render wireless broadband technology the economically feasible
alternative for high-speed network access. We believe that in order to serve the
global broadband wireless access market, a network solution must integrate
point-to-multipoint and point-to-point technologies on a cost-effective basis.
In addition, a solution must be certified by the applicable regulatory agencies
for installation domestically and internationally.

OUR SOLUTION

     Our WAVENET BROADBAND WIRELESS ACCESS portfolio of systems includes
point-to-multipoint and point-to-point wireless systems that connect end-users
to the Internet and public and private communication networks. Our systems allow
a service provider to offer high-speed network access to the end-user as a
cost-effective alternative to wired services. These systems assure service
providers a quick time-to-market by permitting rapid installation of complete
high-speed communication networks. In addition, we design our systems to be
compliant with domestic and international standards. We incorporate a worldwide
service organization that provides customer support 24 hours a day, 7 days a
week and offers network design and installation services.

     The following describes the key benefits of our broadband wireless access
solution:

         COST-EFFECTIVE DESIGN AND IMPLEMENTATION. Our systems provide a
     cost-effective combination of point-to-multipoint broadband wireless access
     and high-speed point-to-point voice and data transmission.

         RAPID INSTALLATION. Our systems are shipped off-the-shelf and are easy
     to install. We believe that our systems are extremely reliable. Our
     license-exempt products do not require frequency coordination or licensing,
     eliminating many of the time-consuming processes required in planning,
     coordinating and installing traditional radio technology. License-exempt
     operation permits rapid installation to meet customer demand for broadband
     wireless access.

         SCALABILITY. Our systems are scalable. As more users are added to a
     network, a central base station that may have initially been equipped with
     a single transmitter can be easily upgraded to accommodate up to ten
     transmitters.

         REMOTE MANAGEMENT. Our standard network management applications include
     a simple network management protocol and a secure Web-based browser
     interface. These interfaces allow the system to be managed and administered
     remotely through the Internet.

         NETWORK COMPATIBILITY. Our wireless systems provide built-in routing
     and support industry standard protocols that allow data to be transported
     at carrier-quality standards.

     Our systems address a broad range of applications in different markets.
Examples of these applications include:

     o    ENABLING INTERNET SERVICE PROVIDERS TO OFFER DIRECT INTERNET ACCESS.
          Digital Wireless Communications, a wireless Internet service provider
          based in Savannah, Georgia, focuses on delivering high-speed Internet
          service to the small office and home office marketplace. Our WAVENET
          ACCESS product permits Digital Wireless Communications to establish
          direct Internet access for its customers. This eliminates the need to
          coordinate line access with the incumbent communication service
          provider and ensures faster availability of services to its customers.

     o    RAPIDLY INSTALLING NEW NETWORKS FOR COMMUNICATION SERVICE PROVIDERS.
          Central City Online, also known as EZNET Total Access, an Internet
          service provider based in Huntington, West Virginia, uses our WAVENET
          wireless systems to provide high-speed Internet access in direct
          competition with the incumbent communication service provider. Our
          WAVENET systems have enabled EZNET to become a competitive


                                       35
<PAGE>

          high-speed wireless Internet service provider in West Virginia. EZNET
          is in the process of launching wireless services across nine states
          encompassing the mid-Atlantic region.

     o    SUPPLEMENTING TELEPHONE OPERATING COMPANIES' EXISTING WIRED NETWORKS.
          Northern Indiana Telephone Company, or NetNITCO, was unable to meet
          customer demand for high-speed Internet access due to limitations in
          copper-based DSL. Our WAVENET ACCESS system allowed NetNITCO to
          provide high-speed data services to its entire service area thereby
          increasing NetNITCO's customer base.

     o    ESTABLISHING COMMUNICATION NETWORKS IN REGIONS WITHOUT EXISTING
          INFRASTRUCTURES. In many parts of the world, communication networks
          are incapable of supporting the increasing amount of high-speed data
          traffic due to inadequate or poorly maintained equipment. Netcom,
          S.A., a communication service provider based in Haiti, determined that
          reliable dial-up service was not available in Haiti. By installing our
          WAVENET broadband wireless system, Netcom is now able to supply its
          Haitian customers with reliable high-speed data services.

     o    ESTABLISHING PRIVATE CORPORATE NETWORKS. Unibanco, a private banking
          enterprise in Brazil, created a dedicated network to meet its branch
          banking communications needs. Our WAVENET ACCESS wireless system was
          selected because the local service provider could not supply the
          network facilities in time to meet Unibanco's requirements. The
          resulting network supports voice and high-speed data communications
          between Unibanco's headquarters and its branch facilities.

STRATEGY

     Our goal is to be the global broadband wireless access solution of choice
for Internet and communication service providers, telephone operating companies
and private network operators. Our strategy for achieving this goal includes the
following core elements:

         INTRODUCING NEW BROADBAND WIRELESS ACCESS TECHNOLOGIES. We are devoting
     substantial resources to the development of new point-to-multipoint
     broadband wireless access technologies. For example, this year we expect to
     introduce STARPORT, a broadband access system designed for the residential,
     small office and home office markets. Also this year, we expect to begin
     shipping the WAVENET ACCESS 3500, a point-to-multipoint system designed
     exclusively for use in the licensed spectrum in the international market.

         LEVERAGING STRATEGIC RELATIONSHIPS. We have entered into a strategic
     relationship with TRW which provides us with technology that we use in our
     STARPORT system. We anticipate forming strategic relationships with
     additional partners to market and sell STARPORT into the residential, small
     office and home office markets. These partners may include Internet and
     communication service providers and telephone operating companies. We
     intend to leverage these relationships in order to develop a global market
     for STARPORT. In the future we may enter into additional strategic
     relationships to enhance existing, or develop market opportunities.

         EXPANDING GLOBAL MARKET PRESENCE. We intend to add additional direct
     sales and sales support resources within the United States and to increase
     our direct sales presence in Europe, Asia and Latin America. In addition to
     expanding our field sales and systems engineering forces, we intend to
     continue to build additional sales channels, both in the United States and
     international markets, to expand the distribution of our products. We
     expect to continue to establish distribution relationships with service
     providers, distributors and value-added resellers to further penetrate our
     target markets.

         EMPHASIZING RESEARCH AND DEVELOPMENT. We have invested significant
     resources in research and development, particularly in the areas of radio
     frequency engineering, software and network protocol development. We intend
     to increase our investment in research and development substantially in
     order to maintain and enhance our technological position. By building on
     our expertise in developing broadband wireless access technology, we intend
     to develop high-performance product lines that will address the needs of
     global wireless broadband markets.

         CONTINUING TO DELIVER HIGH-QUALITY CUSTOMER SERVICE AND SUPPORT. We
     provide pre- and post-installation support, with 24 hours per day, 7 days a
     week coverage on a global basis. We are committed to providing exceptional
     service, and we intend to continually enhance our customer service and
     support capabilities in order to address the needs of existing and new
     markets.

TECHNOLOGY

     We believe that we have industry-leading multidisciplinary expertise in the
development of broadband wireless access solutions and that our products
incorporate several technologies that provide us with advantages relative to our
competitors.

         POINT-TO-MULTIPOINT PROTOCOLS. We have applied our software design
     expertise to develop robust point-to-multipoint networking protocols that
     allow multiple users to have access in a radio environment without
     interfering with each other. We have implemented a sophisticated set of
     software resources, including digital signal processing, network routing
     and network management, to address many of the unique challenges of
     wireless environments. Some of these challenges include interference,
     signal fading, path obstructions, signal absorption, security, capacity
     requirements and shared operations with other radio systems.

         SPREAD SPECTRUM TECHNOLOGY. Spread spectrum transmission is a method
     whereby the original signal is spread over a wide range of frequencies so
     that the original signal is difficult to detect and is very resistant to
     interference from other signals. Some of our WAVENET ACCESS systems use a
     form of radio transmission technology known as frequency hopping spread
     spectrum. In frequency hopping, the transmitter sends at one frequency for
     a period of time and then hops to another frequency and sends again with
     the original signal being decoded at the receiving end. Our STARPORT system
     uses a form of radio transmission technology known as direct sequence
     spread spectrum, a technique that combines an information signal with a
     pseudo-random signal to produce a final signal significantly greater in
     bandwidth than the original information signal, with improved interference
     resistance. We believe that our STARPORT system will deliver extremely
     reliable operation in situations where other wireless-based technologies
     might suffer from degraded performance.

         IP-OVER-ATM. Our STARPORT systems employ Internet protocol, or IP, over
     asynchronous transfer mode, or ATM, transport. IP is the leading industry
     standard for data transmission within the information technology sector and
     is typically used by Internet access providers to transmit data over the
     Internet. ATM is the preferred telecommunications industry standard for
     switching and transmission of voice and data, and is typically used by
     telephone operating companies in their networks. IP-over-ATM transport is a
     method for carrying IP traffic over ATM networks. We offer solutions based
     on IP, ATM and IP-over-ATM transport, allowing us to market our products to
     both Internet service providers and telephone operating companies with
     minimum disruption to their network architectures.

         ROUTER-BASED WIRELESS NETWORKS. We use a router-based architecture for
     our WAVENET ACCESS wireless systems, versus many of our competitors who use
     bridge-based architectures. The advantages of routing systems include
     scalability, control and security. Unlike bridge-based systems where IP
     traffic is bridged to all network nodes, in a router-based system, IP
     traffic is routed to desired locations eliminating excess broadcast
     traffic. By reducing the excess broadcast traffic, our router-based systems
     greatly improve the bandwidth efficiency of our networks in comparison to
     systems that do not have internal router capability.

         DIGITAL COMMUNICATION TECHNOLOGY. Our strategic relationship with TRW
     provides us with access to advanced digital communication technology,
     including innovative protocols, algorithms and digital signal processing.
     Scientific technology licensed to us by TRW as part of the STARPORT
     initiative includes direct sequence spread spectrum waveforms, multiple
     access control schemes, quality of service mechanisms and element
     management interfaces.

         WEB-BASED NETWORK MANAGEMENT. Our products come with WIRELESS
     NETMANAGER, a secure Web-based network management system that gives our
     clients the ability to easily manage their networks, download software
     upgrades, and change or configure software parameters. Additionally,
     WIRELESS NETMANAGER allows us to access and analyze our customers' systems
     from any location through the Internet, giving us the ability to provide
     remote customer support to clients, 24 hours per day, 7 days a week.

PRODUCTS

     We manufacture a complete suite of broadband wireless access systems that
provide point-to-multipoint, point-to-point and high-capacity transport. Our

complete our total network solution.

WAVENET BROADBAND WIRELESS ACCESS SYSTEMS

     Our WAVENET BROADBAND WIRELESS ACCESS series is a family of systems
providing broadband wireless access using point-to-multipoint, point-to-point
and high-capacity transport technology that can transmit data over distances of
up to 20 miles. These systems allow a service provider to offer broadband
wireless access as an economic alternative to cable, DSL and fiber optic
technologies. This series includes the following products:

         WAVENET ACCESS. Our WAVENET ACCESS point-to-multipoint system
     interconnects a large number of facilities in a relatively small area. In
     order to serve a larger geographic region and a larger number of
     facilities, multiple WAVENET ACCESS systems are interconnected using
     point-to-point technology. Connection into the end user's local area
     network, or LAN, from the remote WAVENET ACCESS terminal is accomplished
     through an industry standard Ethernet cable.

          o    WAVENET ACCESS 3500. The WAVENET ACCESS 3500 operates in the
               international 3.5 gigahertz, or GHz, band currently accepted as
               the preferred frequency assignment for fixed broadband radio
               access. Up to 7 Mbps of throughput is available to the user.
               Central base stations can be scaled to support transmission rates
               from 2 Mbps to 57 Mbps. This system is specifically designed for
               point-to-multipoint applications in markets outside the United
               States.

          o    WAVENET ACCESS 2458. The WAVENET ACCESS 2458 operates as a full
               duplex radio by using both the 2.4 GHz and 5.8 GHz license-exempt
               bands. Using the 2.4 GHz band for downstream transmission and the
               5.8 GHz band for upstream transmission provides a unique solution
               in high interference environments. Up to 2.4 Mbps throughput is
               available to each user. Central base stations can be scaled to
               support transmission rates from 2 to 30 Mbps. This system is
               designed for point-to-multipoint applications in the United
               States and selected international markets.

          o    WAVENET ACCESS 2400. The WAVENET ACCESS 2400 operates in the 2.4
               GHz license-exempt band and is European Telecommunications
               Service Institute, or ETSI-, approved. With user throughput of up
               to 1 Mbps and central base stations which are scaled to support
               transmission rates of up to 10 Mbps, it allows an economical
               alternative to T-1 and other dedicated leased lines.

         WAVENET LINK. The WAVENET LINK series is a family of point-to-point
     products using the license-exempt 5 GHz band, available in the United
     States and in an increasing number of other countries. Our WAVENET LINK
     system transports data traffic from one location to another, typically in
     local distribution applications. Our WAVENET LINK systems can interconnect
     high-speed data networks between buildings or facilities within the same
     metropolitan area and are characterized by low end-to-end signal delay,
     ease of installation and simplicity in use.

          o    WAVENET LINK EX. The WAVENET LINK EX is a cost-effective product
               capable of transporting up to 16 Mbps over a distance of up to 10
               miles. The radio is mounted outdoors, close to the antenna, to
               minimize transmission losses, and is connected to the user's
               local access network or in-building distribution system with an
               industry standard Ethernet cable. Although primarily used in
               point-to-point applications, the product can be used to implement
               a point-to-multipoint system with a 100 Mbps effective central
               base station capacity and a 16 Mbps user throughput.

          o    WAVENET LINK 4X. The WAVENET LINK 4X provides a cost-effective
               solution for access requirements as well as cellular base station
               connectivity with capacities of up to 4 x 2.048 Mbps. This system
               features an embedded simple network management protocol. The
               indoor unit, or IDU, provides all user interfaces including 2.048
               Mbps ports, simple network management protocol access and
               external alarm input.

         WAVENET TRANSPORT. Our WAVENET TRANSPORT high-capacity wireless systems
     are similar to our point-to-point systems but provide considerably higher
     data transport rates. These systems transfer


                                       38
<PAGE>

     aggregated traffic between base stations and service providers' backbone
     systems. Like our point-to-point systems, our WAVENET TRANSPORT systems are
     characterized by low end-to-end signal delay and simple installation.

          o    WAVENET TRANSPORT DX. The WAVENET TRANSPORT DX series is a family
               of licensed digital microwave radios operating from 13 to 38 GHz,
               with digital capacities of up to 34 Mbps. This system is targeted
               toward high-speed data transport in selected international
               markets.

          o    WAVENET TRANSPORT MX. The WAVENET TRANSPORT MX is a line-of-sight
               digital radio transmission solution operating in millimeter wave
               frequency bands for voice, high-speed data, Internet and video
               traffic. The WAVENET TRANSPORT MX supports extensive scalable
               data rates up to 100 Mbps.

STARPORT

     We are currently testing in the field a new system called STARPORT, which
we intend to commercially introduce during 2000. STARPORT is a
point-to-multipoint broadband wireless access system that does not require a
line-of-sight between transmission and reception points and supports high-speed
IP-over-ATM traffic. The current architecture supports operation in the 5.8 GHz
license-exempt frequency band and we expect future development to support
operation in additional frequency bands. STARPORT is designed as a
cost-effective alternative to wire-based cable, DSL or fiber-optic technologies
and is intended to allow a service provider to rapidly supply services, such as
high-speed Internet access, throughout a service area. STARPORT is designed to
be installed by the consumer without the need for the communication service
provider to supply a professional technician. STARPORT consists of base station
units and customer premises units. STARPORT is specifically designed for the
residential, small office/home office markets. We expect that the consumer will
be able to connect an interface cable from STARPORT to a personal computer and
then automatically receive broadband service at data rates comparable to typical
DSL service. The base station units can support data rates of up to 4.3 Mbps per
end-user. STARPORT uses ATM-based network architecture allowing communication
service providers to deliver bandwidth on demand to their end-users. The
technology used in this system is licensed from TRW, Inc. and is subject to
certain restrictions. See "--Strategic Relationship with TRW" and "Certain
Transactions--Strategic Relationship with TRW."

LEGACY PRODUCTS

     Multipoint Networks, Inc. developed, manufactured and marketed
point-to-point and point-to multipoint network products, called the RAN series,
prior to its acquisition by Wireless, Inc. The RAN 64/25 and 128/50 are licensed
wireless systems for low data rate connectivity. The RAN 64/25 and 128/50
support a 64 kilobit per second, or kbps, data circuit in a 25 kilohertz, or
kHz, radio channel or a 128 kbps data circuit in a 50 kHz radio channel,
respectively. These systems are typically used to support low-speed traditional
data networks, such as automated teller machine networks.

CUSTOMERS

     We have a globally diversified customer base consisting of Internet and
communication service providers, telephone operating companies and private
network operators. During the 12-month period ended December 31, 1999, 49
customers purchased more than $100,000 of our products and 8 customers purchased
more than $500,000 of our products. In the year ended December 31, 1999, one
customer, Celular de Telefonia, accounted for approximately 13.9% of our
revenues. No other customer represented over 10% of revenues in this period.
Approximately 57.4% of our revenues were derived from ten customers in 1999.

SALES AND MARKETING

     We market our systems and services globally through our direct sales force
and through a distribution network. We have sales and service offices located in
the United States, Europe, Latin America and Asia. Our distribution network
includes the following channels: systems integrators and distributors, value
added resellers, telephone operating companies and Internet and communication
service providers.

     Our direct sales managers provide support to all of the distribution
channels in their geographic territories. They work closely with our channel
partners, participating in end-user briefings, proposals, product training
sessions, end-user seminars, trade shows and other demand-generating activities.
In addition, in partnership with


                                       39
<PAGE>

our indirect channels, our direct sales managers are involved in generating and
qualifying end-user leads that result in sales.

     Our distributors are responsible for identifying potential business
customers, selling our systems as part of complete solutions and installing and
supporting the equipment at end-user sites. We generally establish relationships
with distributors through written agreements that provide pricing, terms and
conditions under which they may purchase our systems for resale. These
agreements are generally non-exclusive, may be terminated at will and do not
prevent these distributors from carrying competing lines or require them to
attain specific sales levels. We provide significant sales, marketing, training
and technical support to our distributors.

CUSTOMER SUPPORT

     We complement our products with a worldwide service organization that
provides product support, network and radio system design, turnkey installation,
maintenance and field engineering. Our distributors are typically responsible
for installation, maintenance and support services to their customers, and we
offer our distributors assistance in providing customer service and support 24
hours per day, 7 days a week.

     We offer a 12-month warranty on our systems and provide both in-warranty
and out-of-warranty repair and return services. Tracking of field returns is
handled by our on-line return material authorization system. Our manufacturing
department uses an on-line material control system allowing us to track product
and customer trends and history.

     Our customer service department also issues technical support notes,
customer service bulletins, and field support notes to keep our customers and
distributors apprised of any changes, issues or concerns regarding product
performance or need for upgrades.

RESEARCH AND DEVELOPMENT

     We have assembled a team of engineers with significant telecommunications
and networking industry experience. Our engineers have expertise in radio
design, wireless networking protocols, data networking, hardware and software.

     Our current product development plans focus on the commercialization of our
STARPORT point-to-multipoint system and other next generation systems. We use
digital signal processors and other digital components to reduce the cost of our
systems.

     We have made, and will continue to make, a substantial investment in
research and development. We believe that our research and development efforts
are key to our ability to maintain technical competitiveness and to deliver
innovative products that address the needs of the market. However, our product
development efforts may not result in commercially successful products and may
be rendered obsolete by changing technology or new product announcements by
other companies.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

     We rely upon a combination of patents, trademarks, trade secrets,
copyrights and a variety of other measures to protect our intellectual property.
We currently hold two U.S. patents and have two patent applications pending
before the U.S. Patent and Trademark Office relating to our point-to-point
wireless networking technology. We also share ownership of two patent
applications pending before the U.S. Patent and Trademark Office, obtained under
a Purchase and License Agreement with TRW, relating to our STARPORT
point-to-multipoint wireless networking technology. In addition, under the
Purchase and License Agreement with TRW, we obtained rights in technology in the
field of wireless communications systems that may lead to additional patent
applications. We currently also have registered trademarks for the marks
"WAVENET," and "RAN" and applications pending before the U.S.Patent and
Trademark Office for additional marks, including "STARPORT," and the Wireless
logo. Although we rely on patent, copyright, trade secret and trademark laws to
protect our technology, we believe that factors such as the technological and
creative skill of our personnel, new product developments, frequent product
enhancements and reliable product maintenance are more essential to establishing
and maintaining technology leadership position.

     We generally enter into confidentiality or license agreements with our
employees, consultants, service providers, customers and corporations with whom
we have strategic relationships, and generally control access to


                                       40
<PAGE>

and distribution of our software, documentation and other proprietary
information. In addition, we often incorporate the network designs of our
customers into our solutions and have obligations with respect to the use and
disclosure of this information.

     We rely on licensed technology for use in our broadband wireless access
systems. We may not be able to maintain these licensing arrangements, or we may
be unable to maintain them on affordable terms. If these license agreements were
not renewed, our business would be severely harmed, and we would not be able to
ship product for the broadband wireless access market. See "Risk Factors--We
depend upon technology licensed from third parties, and if we do not maintain
these license arrangements, our business will be seriously harmed."

     The market for broadband wireless access products and systems is
characterized by vigorous protection and pursuit of intellectual property
rights. From time to time, we may receive notice of claims of infringement of
other parties' proprietary rights. Any claims of infringement, whether or not
they have merit, could result in litigation which could severely harm our
business. See "Risk Factors--Our business model depends upon obtaining and
protecting our intellectual property, and if we fail to protect our proprietary
rights, our business could be harmed" and "--We may become involved in costly
and time consuming litigation over proprietary rights."

GOVERNMENT REGULATION

     Our systems intentionally radiate radio frequency energy, and therefore
must comply with regulations in the countries where we sell and install our
systems. The process of verifying compliance with radio and network regulations
is known as system certification, and this must be granted before a system is
offered commercially for sale. The Federal Communications Commission, or FCC,
certifies systems we sell and install in the United States. Some regions of the
world, such as Latin America and the Philippines, accept FCC certification as
sufficient approval for operation within these regions. The European
Telecommunications Standards Institute, or ETSI, certifies systems we sell and
install in Europe. Many countries also require additional testing to certify
compliance to local standards and requirements, in addition to FCC or ETSI
rules.

     Our systems operate in both licensed and license-exempt frequency
assignments. A licensed frequency assignment requires that, prior to installing
our systems, the operator obtain a conditional license from the appropriate
regulatory body for a specific frequency allocation. A license-exempt frequency
assignment allows an operator to install and activate our systems without
notifying any authority. In the United States, operation of unlicensed radio
communications equipment is subject to the conditions that no harmful
interference is caused to authorized users of the band, and that interference,
including interference that may cause undesired operation, must be accepted from
all other users of the band. This includes other unlicensed operators,
authorized operators such as amateur licensees, Industrial, Scientific and
Medical equipment, and U.S. Government operations. Unlicensed operators that
cause harmful interference to authorized users, or that exceed permitted radio
frequency emission levels, may be required to cease operations until the
condition causing the harmful interference or excessive emissions has been
corrected.

     The delays inherent in this regulatory approval process may cause the
rescheduling, postponement or cancellation of the installation of
telecommunications systems by our customers which, in turn, may significantly
reduce sales of systems to these customers. The failure to comply with current
or future regulations or changes in the interpretation of existing regulations
in a particular country could result in the suspension or cessation of sales in
that country, restrictions on our development efforts and those of our
customers, render current systems obsolete, or increase the opportunity for
additional competition. These regulations or changes in interpretation of these
regulations could require us to modify our products and incur substantial
compliance costs.

MANUFACTURING

     Our manufacturing operations occupy 38,000 square feet of our facility in
Santa Clara, California and consist of planning, procurement, final assembly,
testing, quality control, shipping, receiving and stock management.

     We design and develop a number of the key components of our products,
including printed circuit boards, mechanical enclosures and software. We
outsource the majority of our sub-assembly operations, and we utilize strategic
ISO 9000 certified local and offshore manufacturing partners to provide
sub-assembly of the printed circuit boards and key components. We also outsource
the sub-assembly of the printed circuit boards for some of our WAVENET ACCESS
and WAVENET LINK systems. We provide exact specifications to our manufacturing
partners that


                                       41
<PAGE>

provide the sub-assemblies and components for each product. We then conduct
final assembly, burn-in, test and shipment of our products from our headquarters
in Santa Clara, California.

     Our manufacturing team works closely with our engineers to manage the
supply chain. We determine the components that are incorporated in our products
and select the appropriate suppliers of these components. All materials used in
our products are processed through a full qualification cycle and are controlled
by an approved vendor list.

     Our approach to manufacturing provides the flexibility of outsourcing while
maintaining quality control of delivered products to customers. We believe that
this approach allows us to respond to rapid growth and sudden market shifts. Key
factors that influence our manufacturing operations are cost reduction, quality,
time-to-market and supply of materials. Any interruption in the operations of
our manufacturing partners or material suppliers would harm our ability to meet
scheduled product deliveries to our customers.

     We use a rolling four-month forecast based upon anticipated product orders
to determine our material requirements. Lead times for the materials and
components that we order vary significantly and depend on factors such as
specific supplier, contract terms and demand for a component at a given time.
We, along with our contract manufacturers, may terminate our contracts without
cause at any time. At that time, the terminating party must honor all open
purchases. We obtain parts and components through purchase orders and have no
long-term commitments regarding supply or price from these suppliers. We have
established second source manufacturing and material suppliers to provide parts
and components within weeks of losing these suppliers. However, the loss of any
of our suppliers could prevent us from meeting our scheduled product deliveries
to our customers and could materially harm our business, results of operations
and financial condition.

STRATEGIC RELATIONSHIP WITH TRW

     We entered into a Purchase and License Agreement with TRW on January 14,
2000. Under the agreement, we purchased and obtained exclusive license rights in
point-to-multipoint wireless networking technology, generally referred to as the
STARPORT technology. Any products we develop based on such technology may only
be sold by us with base stations configured for outdoor use. Sales of products
containing the STARPORT technology with base stations configured for indoor use
or to the U.S. Government--including organizations in which the U.S. is a
member, such as NATO--must be made through TRW or its licensees. TRW also has a
license in any improvements made by us upon the STARPORT technology. If we do
not offer a commercial version of a product containing the STARPORT technology
for sale by July 14, 2001, we will lose our exclusive license with TRW. The
STARPORT technology was originally developed by TRW Systems and Information
Technology Group for military communications. TRW is an international company
that provides advanced technology products and services. The principal
businesses of TRW and its subsidiaries are the design, manufacture and sale of
products and the performance of systems engineering, research and technical
services for industry and the U.S. Government in the automotive, aerospace and
information systems markets. In connection with this agreement, TRW acquired
approximately 18% of our capital stock outstanding prior to this offering.

COMPETITION

     The broadband wireless access market is rapidly evolving and highly
competitive. We believe that our business is affected by the following
competitive factors:

     o    cost;

     o    ease of installation;

     o    technical support and service;

     o    sales and distribution capability;

     o    breadth of product line;

     o    conformity to industry standards; and

     o    implementation of additional product features and enhancements.

     We expect that competition in the broadband wireless access market will
increase in the future. We currently compete against wireless broadband access
equipment manufacturers including Adaptive Broadband Corporation, BreezeCom,

Wavtrace, Inc. in the

point-to-multipoint market and BreezeCom, Digital Microwave Corporation, Lucent
and P-Com, Inc. in the point-to-point market. In addition, well capitalized
wireless equipment manufacturers including Ericsson, Inc., Motorola, Inc., Nokia
Corporation, QUALCOMM Incorporated and Siemens AG are potential entrants into
either market. Our broadband wireless access technology also competes with wired
solutions such as cable, DSL, fiber optic systems and high-speed lines leased
from communication service providers, such as T-1 lines.

     Increased competition is likely to result in price reductions, shorter
product life cycles, reduced gross margins, longer sales cycles and loss of
market share, any of which would seriously harm our business. We cannot assure
you that we will be able to compete successfully against current or future
competitors or that competitive pressures we face will not seriously harm our
business and results of operations. Many of our competitors have longer
operating histories, larger installed customer bases, substantially greater name
recognition, and greater financial, sales and marketing, technical,
manufacturing, and distribution resources than us.

FACILITIES

     Our principal operations are located in Santa Clara, California. We lease
approximately 55,000 square feet for our corporate headquarters that includes
manufacturing, sales and marketing, research and development, customer service
and support, and finance and administration. This lease expires on July 31,
2006. In addition, we have short-term leases for our various sales offices. We
believe our current facilities will be adequate to meet production needs for the
foreseeable future.

EMPLOYEES

     As of December 31, 1999 we had a total of 91 employees, of which 31 were in
operations and manufacturing, 25 were in sales and marketing, 18 were in
research and development, 5 were in customer service and support, and 12 were in
finance and administration. None of our employees is represented by a labor
union. We have not experienced any work stoppages and consider relations with
our employees to be good.

LEGAL PROCEEDINGS

     We are not currently a party to any material litigation.

COMPOSITION OF THE BOARD

       Immediately prior to the completion of this offering, we will amend and
restate our certificate of incorporation to adopt certain public company-style
provisions. Under our amended and restated certificate of incorporation, our
board of directors will be divided into three classes, with each class serving
for a term of three years. At each annual meeting of stockholders, directors
will be elected by the holders of common stock to succeed the directors whose
terms are expiring. Our Board has resolved that Messrs. Millet and Filat will be
Class I directors whose term will expire in 2001, Mr. Rivelli and Dr. Ko will be
Class II directors whose terms will expire in 2002 and Messrs. Gibson, Palumbo
and Silverman will be Class III directors whose terms will expire in 2003. With
respect to each class, a director's term will be subject to the election and
qualification of their successor, or their earlier death, resignation or
removal.

BOARD COMMITTEES

       We have established an audit committee composed of independent directors,
which reviews and supervises our financial controls, including the selection of
our auditors, reviews our books and accounts, meets with our officers regarding
our financial controls, acts upon recommendations of our auditors and takes
further actions as the audit committee deems necessary to complete an audit of
our books and accounts, as well as other matters which

                                       46
<PAGE>

may come before it or as directed by the board. The audit committee currently
consists of three directors, Messrs. Millet and Silverman and Dr. Ko.

       We have established a compensation committee, which reviews and approves
the compensation and benefits for our executive officers, administers our stock
plans and performs other duties as may from time to time be determined by the
board. The compensation committee currently consists of two directors, Messrs.
Fillat and Rivelli. None of our compensation committee members is, or ever was,
an employee of ours. None of our executive officers serve on the board of
directors or compensation committee of any entity which has one or more
executive officers serving as a member of our board or compensation committee.

DIRECTOR COMPENSATION

       Directors who are also employees do not receive additional compensation
for serving as directors. Non-employee directors receive $10,000 for each year
of board service following each annual meeting. Non-employee directors also
receive $1,000 for attending each regular and special meeting of the full Board
of Directors and $500 for attending each regular or special meeting of a board
committee, plus, in each case, reimbursement for reasonable expenses.
Non-employee directors are also eligible to receive discretionary option grants
and stock issuances under the 2000 Stock Incentive Plan. In addition, under the
2000 Stock Incentive Plan, non-employee directors receive automatic option
grants to purchase 30,000 shares of common stock upon becoming directors and
automatic option grants to purchase 5,000 shares of common stock on the date of
each annual meeting of stockholders. The 2000 Stock Incentive Plan also contains
a director fee option grant program. Should this program be activated in the
future, each non-employee board member will have the opportunity to apply all or
a portion of any annual retainer fee otherwise payable in cash to the
acquisition of an option with an exercise price below the then fair market
value. See "Executive Compensation and Other Information--Employee Benefit
Plans."

LIMITATION OF LIABILITY AND INDEMNIFICATION

       Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors, except liability for:

       o      any breach of their duty of loyalty to the corporation or its
              stockholders;

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

       o      unlawful payments of dividends or unlawful stock repurchases or
              redemptions; or

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

       Such limitation of liability does not apply to liabilities arising under
the federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission. Our certificate of
incorporation and bylaws provide that we shall indemnify our directors and
executive officers and may indemnify our other officers and employees and other
agents to the fullest extent permitted by law. Our bylaws also permit us to
secure insurance on behalf of any officer, director, employee or other agent for
any liability arising out of his or her actions in such capacity, regardless of
whether the bylaws would permit indemnification.

       We have entered into agreements to indemnify our directors and executive
officers in addition to indemnification provided for in our bylaws. These
agreements, among other things, provide for indemnification of our directors and
executive officers for expenses specified in the agreements, including
attorneys' fees, judgments, fines and settlement amounts incurred by any such
person in any action or proceeding arising out of such person's services as a
director or executive officer of Wireless, any subsidiary of Wireless or any
other entity to which the person provides services at our request. In addition,
we maintain directors' and officers' insurance. We believe that these provisions
and agreements are necessary to attract and retain qualified persons as
directors and executive officers.

EXECUTIVE OFFICERS

       Our executive officers are appointed by and serve at the discretion of
our board of directors. There are no family relationships among any of our
directors, officers or key employees.

(1)    250,000 of such shares are conditional upon the company undertaking
       a successful initial public offering prior to December 31, 2000 or
       meeting certain revenue and profit targets in 2000 and are subject to
       repurchase by the company at the original exercise price if such
       conditions are not met on or before December 31, 2000.


(2)    In January 1999 our board of directors resolved to accelerate all of
       Mr. Pai's unvested options as of the date 180 days following the date
       this registration statement is declared effective.

       In 1999, we granted options to purchase up to an aggregate of 4,124,209
shares of our common stock to employees, directors and consultants under our
1997 Stock Plan. Under our 1997 Stock Plan, options were granted to employees,
officers, directors and consultants. Only employees, officers and directors were
eligible to receive "non-statutory stock options," which are intended to qualify
for certain tax treatment, and consultants may receive "nonstanding stock
options," which do not qualify for such treatment. The exercise price of
incentive stock options under the 1997 Stock Plan must be at least equal to the
fair market value of our common stock on the date of grant, as determined in
good faith by our board of directors, while the exercise price of nonstatutory
options must be at least equal to 85% of the fair market value. Holders of more
than 10% of the outstanding voting shares were only granted options with an
exercise price of at least 110% of the fair market value of the underlying stock
on the date of grant, and if such holder has incentive stock options, the term
of the options must not exceed five years. Options granted under the 1997 Stock
Plan generally vest over a four-year period and must be exercised within ten
years.

       The potential realizable value is calculated assuming the aggregate
exercise price on the date of grant appreciates at the indicated rate for the
entire term of the option and that the option is exercised and sold on the last
day of its term at the appreciated price. Stock price appreciation of 5% and 10%
is assumed pursuant to the rules of the Commission. We can give no assurance
that the actual stock price will appreciate over the term of the options at the
assumed 5% and 10% levels or at any other defined level. Actual gains, if any,
on stock option exercises will be dependent on the future performance of our
common stock. Unless the market price of the common stock appreciates over the
option term, no value will be realized from the option grants made to the named
executive officers.

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

       The following table sets forth information with respect to the named
executive officers concerning their exercise of stock options during the year
ended December 31, 1999 and the number and value of shares of common

                                       49
<PAGE>

stock underlying the unexercised options held by them at the close of such year.
No stock appreciation rights were exercised during 1999 and no stock
appreciation rights were outstanding as of December 31, 1999. The value realized
is calculated as the difference between the fair value of the shares at the time
of exercise less the exercise price paid for the shares. The value of
unexercised in-the-money options at December 31, 1999 is calculated on the basis
of the assumed initial public offering price of $          , less the aggregate
exercise price of the options.

EMPLOYEE BENEFIT PLANS

       2000 STOCK INCENTIVE PLAN.

       INTRODUCTION. The 2000 Stock Incentive Plan is intended to serve as the
successor program to our 1997 Stock Option/Stock Issuance Plan. The 2000 plan
was adopted by the board on January 18, 2000 and is expected to be approved by
our stockholders in May 2000. The 2000 plan will become effective when the
underwriting agreement for this offering is signed. At that time, all
outstanding options under our existing 1997 plan will be transferred to the 2000
plan, and no further option grants will be made under the 1997 plan. The
transferred options will continue to be governed by their existing terms, unless
our compensation committee decides to extend one or more features of the 2000
plan to those options. Except as otherwise noted below, the transferred options
have substantially the same terms as will be in effect for grants made under the
discretionary option grant program of our 2000 plan.

       SHARE RESERVE. 8,750,000 shares of our common stock have been authorized
for issuance under the 2000 plan. This share reserve consists of the number of
shares we estimate will be carried over from the 1997 plan plus an additional
increase of approximately 1,300,000 shares. The share reserve under our 2000
plan will automatically increase on the first trading day in January each
calendar year, beginning with calendar year 2001, by an amount equal to three
percent of the total number of shares of our common stock outstanding on the
last trading day of December in the prior calendar year, but in no event will
this annual increase exceed 2,000,000 shares. In addition, no participant in the
2000 plan may be granted stock options or direct stock issuances for more than
875,000 shares of common stock in total in any calendar year.

       PROGRAMS.  Our 2000 plan has five separate programs:

       o the discretionary option grant program, under which eligible
         individuals in our employ may be granted options to purchase shares of
         our common stock at an exercise price not less than the fair market
         value of those shares on the grant date;

       o the stock issuance program, under which eligible individuals may be
         issued shares of common stock directly, upon the attainment of
         performance milestones or the completion of a specified period of
         service or as a bonus for past services;

       o the salary investment option grant program, under which our executive
         officers and other highly compensated employees may be given the
         opportunity to apply a portion of their base salary each year to the
         acquisition of special below market stock option grants;

                                       50
<PAGE>

       o the automatic option grant program, under which option grants will
         automatically be made at periodic intervals to eligible non-employee
         board members to purchase shares of common stock at an exercise price
         equal to the fair market value of those shares on the grant date; and

       o the director fee option grant program, under which our non-employee
         board members may be given the opportunity to apply a portion of any
         retainer fee otherwise payable to them in cash each year to the
         acquisition of special below-market option grants.

       ELIGIBILITY. The individuals eligible to participate in our 2000 plan
include our officers and other employees, our board members and any consultants
we hire.

       ADMINISTRATION. The discretionary option grant and stock issuance
programs will be administered by our compensation committee. This committee will
determine which eligible individuals are to receive option grants or stock
issuances under those programs, the time or times when the grants or issuances
are to be made, the number of shares subject to each grant or issuance, the
status of any granted option as either an incentive stock option or a
nonstatutory stock option under the federal tax laws, the vesting schedule to be
in effect for the option grant or stock issuance and the maximum term for which
any granted option is to remain outstanding. The compensation committee will
also have the authority to select the executive officers and other highly
compensated employees who may participate in the salary investment option grant
program in the event that program is put into effect for one or more calendar
years.

       PLAN FEATURES.  Our 2000 plan will include the following features:

       o the exercise price for any options granted under the 2000 plan may be
         paid in cash or in shares of our common stock valued at fair market
         value on the exercise date. The option may also be exercised through a
         same-day sale program without any cash outlay by the optionee;

       o the compensation committee will have the authority to cancel
         outstanding options under the discretionary option grant program,
         including any transferred options from our 1997 plan, in return for the
         grant of new options for the same or different number of option shares
         with an exercise price per share based upon the fair market value of
         our common stock on the new grant date; and

       o stock appreciation rights may be issued under the discretionary option
         grant program. These rights will provide the holders with the election
         to surrender their outstanding options for a payment from us equal to
         the fair market value of the shares subject to the surrendered options
         less the exercise price payable for those shares. We may make the
         payment in cash or in shares of our common stock. None of the options
         under our 1997 plan have any stock appreciation rights.

       CHANGE IN CONTROL. The 2000 plan will include the following change in
control provisions which may result in the accelerated vesting of outstanding
option grants and stock issuances:

       o in the event that we are acquired by merger or asset sale, each
         outstanding option under the discretionary option grant program which
         is not to be assumed by the successor corporation will immediately
         become exercisable for all the option shares, and all outstanding
         unvested shares will immediately vest, except to the extent our
         repurchase rights with respect to those shares are to be assigned to
         the successor corporation;

       o the compensation committee will have complete discretion to grant one
         or more options which will become exercisable for all the option shares
         in the event those options are assumed in the acquisition but the
         optionee's service with us or the acquiring entity is subsequently
         terminated. The vesting of any outstanding shares under our 2000 plan
         may be accelerated upon similar terms and conditions; and

       o the compensation committee may grant options and structure repurchase
         rights so that the shares subject to those options or repurchase rights
         will immediately vest in connection with a successful tender offer for
         more than fifty percent of our outstanding voting stock or a change in
         the majority of our board through one or more contested elections. Such
         accelerated vesting may occur either at the time of such transaction or
         upon the subsequent termination of the individual's service.

       SALARY INVESTMENT OPTION GRANT PROGRAM. In the event the compensation
committee decides to put this program into effect for one or more calendar
years, each of our executive officers and other highly compensated employees may
elect to reduce his or her base salary for the calendar year by an amount not
less than $10,000 nor more than $50,000. Each selected individual who makes such
an election will automatically be granted, on the first trading day in January
of the calendar year for which his or her salary reduction is to be in effect,
an option to

                                       51
<PAGE>

purchase that number of shares of common stock determined by dividing the salary
reduction amount by two-thirds of the fair market value per share of our common
stock on the grant date. The option will have exercise price per share equal to
one-third of the fair market value of the option shares on the grant date. As a
result, the option will be structured so that the fair market value of the
option shares on the grant date less the exercise price payable for those shares
will be equal to the amount of the salary reduction. The option will become
exercisable in a series of twelve equal monthly installments over the calendar
year for which the salary reduction is to be in effect.

       AUTOMATIC OPTION GRANT PROGRAM. Each individual who first becomes a
non-employee board member at any time after the effective date of this offering
will receive an option grant to purchase 30,000 shares of common stock on the
date such individual joins the board. In addition, on the date of each annual
stockholders meeting held after the effective date of this offering, each
non-employee board member who is to continue to serve as a non-employee board
member, including each of our current non-employee board members, will
automatically be granted an option to purchase 5,000 shares of common stock,
provided such individual has served on the board for at least six months.

       Each automatic grant will have an exercise price per share equal to the
fair market value per share of our common stock on the grant date and will have
a term of 10 years, subject to earlier termination following the optionee's
cessation of board service. The option will be immediately exercisable for all
of the option shares; however, we may repurchase, at the exercise price paid per
share, any shares purchased under the option which are not vested at the time of
the optionee's cessation of board service. One-third of the shares subject to
the initial 30,000 share grant will be fully vested at the time of the grant.
The remaining two-thirds of such shares will vest in a series of two successive
annual installments upon the optionee's completion of each year of board service
over the two-year period measured from the grant date. However, the shares will
immediately vest in full upon certain changes in control or ownership or upon
the optionee's death or disability while a board member. The shares subject to
each annual 5,000-share automatic grant will vest upon the optionee's completion
of the one year period measured from the grant date.

       DIRECTOR FEE OPTION GRANT PROGRAM. If this program is put into effect in
the future, then each non-employee board member may elect to apply all or a
portion of any cash retainer fee for the year to the acquisition of a
below-market option grant. The option grant will automatically be made on the
first trading day in January in the year for which the non-employee board member
would otherwise be paid the cash retainer fee in the absence of his or her
election. The option will have an exercise price per share equal to one-third of
the fair market value of the option shares on the grant date, and the number of
shares subject to the option will be determined by dividing the amount of the
retainer fee applied to the program by two-thirds of the fair market value per
share of our common stock on the grant date. As a result, the option will be
structured so that the fair market value of the option shares on the grant date
less the exercise price payable for those shares will be equal to the portion of
the retainer fee applied to that option. The option will become exercisable in a
series of twelve equal monthly installments over the calendar year for which the
election is in effect. However, the option will become immediately exercisable
for all the option shares upon the death or disability of the optionee while
serving as a board member.

       ADDITIONAL PROGRAM FEATURES. Our 2000 plan will also have the following
features:

       o outstanding options under the salary investment and director fee option
         grant programs will immediately vest if we are acquired by a merger or
         asset sale or if there is a successful tender offer for more than 50%
         of our outstanding voting stock or a change in the majority of our
         board through one or more contested elections;

       o limited stock appreciation rights will automatically be included as
         part of each grant made under the salary investment option grant
         program and the automatic and director fee option grant programs, and
         these rights may also be granted to one or more officers as part of
         their option grants under the discretionary option grant program.
         Options with this feature may be surrendered to us upon the successful
         completion of a hostile tender offer for more than 50% of our
         outstanding voting stock. In return for the surrendered option, the
         optionee will be entitled to a cash distribution from us in an amount
         per surrendered option share based upon the highest price per share of
         our common stock paid in that tender offer;

       o the board may amend or modify the 2000 plan at any time, subject to any
         required stockholder approval; and

       o the 2000 plan will terminate no later than January 18, 2010.

       2000 EMPLOYEE STOCK PURCHASE PLAN.

       INTRODUCTION. Our 2000 Employee Stock Purchase Plan was adopted by the
Board on January 18, 2000 and is expected to be approved by our stockholders in
May 2000. The plan will become effective when the underwriting agreement for
this offering is signed. The plan is designed to allow our eligible employees
and the eligible employees our participating subsidiaries to purchase shares of
common stock, at semi-annual intervals, with their accumulated payroll
deductions.

       SHARE RESERVE. 250,000 shares of our common stock will initially be
reserved for issuance. The reserve will automatically increase on the first
trading day in January each calendar year, beginning in calendar year 2001, by
an amount equal to two percent of the total number of outstanding shares of our
common stock on the last trading day in December in the prior calendar year. In
no event will any such annual increase exceed 1,300,000 shares.

       OFFERING PERIODS. The plan will have a series of successive offering
periods, each with a maximum duration of 24 months. The initial offering period
will start on the date the underwriting agreement for the offering covered is
signed and will end on the last business day in April 2002. The next offering
period will start on the first business day in May 2002, and subsequent offering
periods will set by our compensation committee.

       ELIGIBLE EMPLOYEES. Individuals scheduled to work more than 20 hours per
week for more than five calendar months per year may join an offering period on
the start date or any semi-annual entry date within that period. Semi-annual
entry dates will occur on the first business day of May and November each year.
Individuals who become eligible employees after the start date of an offering
period may join the plan on any subsequent semi-annual entry date within that
offering period.

       PAYROLL DEDUCTIONS. A participant may contribute up to 10% of his or her
cash earnings through payroll deductions, and the accumulated deductions will be
applied to the purchase of shares on each semi-annual purchase date. The
purchase price per share will be equal to 85% of the fair market value per share
on the participant's entry date into the offering period or, if lower, 85% of
the fair market value per share on the semi-annual purchase date. Semi-annual
purchase dates will occur on the last business day of January and July each
year. However, a participant may not purchase more than 800 shares on any
purchase date, and not more than 150,000 shares may be purchased in total by all
participants on any purchase date. Our compensation committee will have the
authority to change these limitations for any subsequent offering period.

       RESET FEATURE. If the fair market value per share of our common stock on
any purchase date is less than the fair market value per share on the start date
of the two-year offering period, then that offering period will automatically
terminate, and a new two-year offering period will begin on the next business
day. All participants in the terminated offering will be transferred to the new
offering period.

       CHANGE IN CONTROL. Should we be acquired by merger or sale of
substantially all of our assets or more than fifty percent of our voting
securities, then all outstanding purchase rights will automatically be exercised
immediately prior to the effective date of the acquisition. The purchase price
will be equal to 85% of the market value per share on the participant's entry
date into the offering period in which an acquisition occurs or, if lower, 85%
of the fair market value per share immediately prior to the acquisition.

       PLAN PROVISIONS. The following provisions will also be in effect under
the plan:

       o the plan will terminate no later than the last business day of
         April 2010; and

       o the board may at any time amend, suspend or discontinue the plan,
         subject to any required stockholder approval.

       MULTIPOINT 1996 STOCK OPTION PLAN.

       The Multipoint 1996 Stock Option Plan was assumed in connection with our
acquisition of Multipoint. The 1996 Stock Option Plan was terminated following
the acquisition and no further option grants will be made under the plan,
however, 85,545 options are outstanding under the plan which continue to be
governed by their existing terms. The outstanding options are either incentive
stock options or non-statutory stock options which were granted at an exercise
price of not less than 100% of the fair market value of the Multipoint common
stock on the grant date. In accordance with the terms of the individual stock
option agreements, in the event that we are acquired by merger or asset sale,
the options under the 1996 Stock Option Plan will become fully vested and
exercisable unless they are

                                       53

either (i) assumed or continued by the successor corporation, (ii) replaced with
a comparable option to purchase capital stock of the successor corporation,
(iii) replaced with a cash incentive program which preserves the spreadexisting
on the option shares at the time of the acquisition and provides for subsequent
payout in accordance with the same vesting schedule applicable to such option or
(iv) the acceleration of such options was subject to additional limitations
imposed by the Multipoint board of directors at the time of the option grant.
All repurchase rights shall lapse except to the extent assigned to the successor
corporation in such acquisition.

     SERIES A PREFERRED STOCK. In May 1997, we issued 6,000,000 shares of our
Series A Preferred Stock, of which 3,000,000 shares were issued to Crossroads
Venture Investors II, L.P. at a price of $0.50 per share, resulting in aggregate
proceeds of $1,500,000 and 3,000,000 shares valued at $0.50 per share were
issued to Wi-LAN, Inc. pursuant to a Technology License and Manufacturing
Agreement. As a result of a subsequent restructuring of the license agreement,
1,700,000 of the shares held by Wi-LAN were returned to us, of which 1,400,000
shares were related to the Technology License and Manufacturing Agreement and
300,000 shares were related to the cancellation of a note payable from Wi-LAN to
us.

     SERIES B PREFERRED STOCK. In October 1997, we issued 750,000 shares of our
Series B Preferred Stock at a price of $2.00 per share to Crossroads Venture
Investors III, L.P., resulting in aggregate proceeds of $1.5 million.

     SERIES C PREFERRED STOCK. In August 1998, in connection with the
acquisition of Multipoint Networks, Inc., or Multipoint, all outstanding shares
of the former Series 1 Preferred Stock of Multipoint were exchanged for an
aggregate of 2,146,838 shares of our Series C Preferred Stock. The major holders
of Series 1 Preferred of Multipoint and the major recipients of Series C
Preferred Stock were HMS Capital Partners, Global Private Equity II, L.P., Alta
V, L.P. and John Rodgers. In November 1999, we repurchased 59,983 shares of our
Series C Preferred Stock from Late Stage Fund 1991 L.P. for a price of $1.33 per
share.

     SERIES D PREFERRED STOCK. In March 1999, we issued 6,541,013 shares of our
Series D Preferred Stock at a price of $1.25 per share, resulting in aggregate
proceeds of $8.2 million. Major investors were Crossroads Venture Investors VI,
L.P., DynaFund International, L.P., Dynamics Technology, Inc. and HMS Hawaii
Management Partners. In connection with a loan agreement we also issued warrants
to purchase an additional 48,000 shares of our Series D Preferred Stock to
Silicon Valley Bank at an exercise price of $1.25 per share.

     SERIES E PREFERRED STOCK. In September 1999, we issued 3,600,000 shares of
our Series E Preferred Stock at a price of $2.50 per share, resulting in
aggregate proceeds of $9.0 million and issued warrants at a price of $0.01 per
warrant to purchase an additional 360,000 shares of common stock at an exercise
price of $0.75 per share. GMN Investors II, L.P. and Stratford Equity Partners,
L.P. were the major investors. The conversion price was subsequently reduced to
$2.42 per share pursuant to a resolution by the board of directors on December
21, 1999. In connection with a loan agreement we also issued warrants to
purchase an additional 20,000 shares of our Series E Preferred Stock to Silicon
Valley Bank at an exercise price of $2.50 per share.

     SERIES F PREFERRED STOCK. In January 2000, we issued 3,000,000 shares of
our Series F Preferred Stock at a price of $5.00 per share, resulting in
aggregate proceeds of $15.0 million. TRW Inc. and CECAP Wireless Group, LLC were
the only investors.

       The securities described above were sold pursuant to preferred stock
purchase agreements and an investors' rights agreement on substantially similar
terms, except for terms relating to date and price, under which we made standard
representations, warranties, and covenants, and pursuant to which we provided
the purchasers thereunder with registration rights, information rights, and
rights of first refusal, among other provisions standard in venture capital
financings. Each share of our Series A, Series D and Series F Preferred Stock
will automatically convert into one share of our common stock upon the
completion of the offering. Each share of our Series B Preferred Stock will


                                       55
<PAGE>

automatically convert into 1.1078 shares of our common stock and each share of
our Series C Preferred Stock will automatically convert into 1.0153 shares of
our common stock, in each case after giving effect to an anti-dilution
adjustment resulting from the sales of the Series C and Series D Preferred
Stocks, respectively. Each share of our Series E Preferred Stock will
automatically convert into 1.0331 shares of our common stock after giving effect
to a price adjustment approved by our board of directors in December 1999, as
discussed above.

     In addition to the foregoing, we have issued 7,765,538 shares of our common
stock to various investors at prices ranging from $0.27 per share to $4.00 per
share in connection with the exercise of warrants and options we granted. In
January 2000, in connection with a Purchase and License Agreement with TRW,
Inc., we issued 3,429,352 shares of our common stock to TRW for a price of $5.00
per share. The shares of common stock issued or issuable pursuant to the
exercise of common stock purchase warrants enjoy certain registration rights
different from those enjoyed by holders of our Preferred Stock. See "Description
of Capital Stock--Registration Rights."

     The purchasers of the securities described above included, among others,
the following holders of 5% or more of our capital stock, named executive
officers, directors, and persons associated with them:

LICENSE AND MANUFACTURING AGREEMENT WITH WI-LAN

     We entered into a License and Technology Transfer and Manufacturing
Agreement with Wi-LAN, Inc. on May 14, 1997. Under the license agreement, Wi-LAN
agreed to license and transfer technology to us for 3,000,000 shares of Series A
Preferred Stock valued at $0.50 per share. In 1997, we determined that the
licensed and transferred technology was no longer applicable to our needs. On
June 3, 1998, the license agreement was replaced by a new license agreement and
a new manufacturing agreement. Under the terms of the new agreement, we obtained
a non-exclusive license to certain of Wi-LAN's spread spectrum data
communications technology. Any improvements we make upon the licensed technology
belong to Wi-LAN. We also entered into a manufacturing agreement with Wi-LAN on
June 3, 1998, pursuant to which we obtained sole right to manufacture or have a
third party manufacture products based on the licensed technology. Pursuant to
the new agreement, 1,700,000 of the shares held by Wi-LAN were returned to the
Company, of which 1,400,000 shares were related to the manufacturing agreement
and 300,000 shares were related to the cancellation of a note payable from
Wi-LAN to us. In February 2000, we terminated the manufacturing agreement and,
as a result, the license agreement terminated automatically.

LEASE AGREEMENT

     In May 1997, we leased 12,800 square feet of office space at 3285 Scott
Boulevard, Santa Clara, California. Pursuant to an informal arrangement we
subleased the facility to Momentum Laser, Inc., a company in which Mr. Gibson
and the Crossroads Entities have an ownership interest. Momentum Laser pays all
costs related to the facility. The Company remains obligated under the lease for
monthly lease payments of $18,560 plus maintenance, property tax and insurance
charges. The lease expires in April 2002. We believe that the arrangement is no
less favorable to us than that which would otherwise be entered into with
unaffiliated third parties.

MULTIPOINT NETWORKS, INC. ACQUISITION

     In August 1998, we acquired Multipoint Networks, Inc., or Multipoint. In
connection with this acquisition, the former common stockholders of Multipoint
exchanged all outstanding shares of common stock of Multipoint for an aggregate
of 2,746,053 shares of our common stock. The former Multipoint Series 1
preferred stockholders exchanged all outstanding shares of their Multipoint
Series 1 preferred stock for an aggregate of 2,146,838 shares of our Series C
Preferred Stock. In November 1999, we repurchased 59,983 shares of Series C
Preferred Stock from one investor. Certain holders of 5% or more of our capital
stock, executive officers, directors and persons associated with them acquired
our Series C Preferred Stock as a result of the Multipoint acquisition. See
"--Sales of Securities."

STRATEGIC RELATIONSHIP WITH TRW

     We entered into a Purchase and License Agreement with TRW on January 14,
2000. Under the agreement, we purchased and obtained an exclusive, including as
to TRW, royalty-free worldwide license in point-to-multipoint wireless
networking technology, generally referred to in this prospectus as the STARPORT
technology. Any products we develop based on such technology may only be sold
with base stations configured for outdoor use. Sales of products containing the
STARPORT technology with base stations configured for indoor use or to the U.S.
Government--including organizations in which the U.S. is a member, such as
NATO--must be made through TRW or its licensees. The agreement provides TRW with
a royalty-free worldwide non-exclusive license in any improvements made by us
upon the STARPORT technology for the manufacture and sale of products to the
U.S. Government. If we do not offer a commercial version of a product containing
the STARPORT technology for sale by July 14, 2001, unless the delay is the fault
of TRW or attributable to certain specified reasons, we will lose our exclusive
license with TRW.

     The STARPORT technology was originally developed by TRW Systems and
Information Group for military communications. TRW is an international company
that provides advanced technology products and services. The principal
businesses of TRW and its subsidiaries are the design, manufacture and sale of
products and the performance of systems engineering, research and technical
services for industry and the United States Government in the automotive,
aerospace and information systems markets. In connection with this agreement,
TRW acquired approximately 18% of our capital stock outstanding prior to the
offering, including 2,300,000 shares of our Series F Preferred Stock and
3,429,352 shares of common stock.


                                       57
<PAGE>

     Under the terms of the Purchase and License Agreement, TRW has agreed to
establish an office for the continued development of STARPORT products to be
staffed by employees of both us and TRW and managed by us. TRW has agreed to
provide substantially all of the supplies, infrastructure and services for this
office. TRW will charge us for services performed by its employees at negotiated
rates, including expenses for overhead, facilities, equipment and general and
administrative expenses. TRW will also provide, at no additional charge, 24
person-months of consultation advice and 12 person-months of assistance in
responding to actual and potential claims regarding infringements of third-party
intellectual property rights in connection with the STARPORT technology. TRW is
required to pay for certain field trials of the STARPORT technology and all
products purchased or manufactured for use in these trials.

     The Purchase and License Agreement also provides that, until January 14,
2003, at our option, TRW will purchase from L3 Communications, Inc. products and
components needed for use in, as well as services to develop and manufacture,
our STARPORT system at a negotiated markup. TRW will also pass through to us any
rights of exclusivity granted to TRW by L3 and any representations and
warranties granted in favor of TRW by L3.

     In consideration of the right and licenses provided under the Purchase and
License Agreement and the technical assistance to be provided by TRW, we have
agreed to pay TRW 10% of the net proceeds of this offering or any private
placement of equity occurring on or before October 14, 2000, until we have paid
TRW an aggregate of $2.5 million. The balance of this amount is due on January
1, 2001, if it has not been paid prior to that date.

     The Purchase and License Agreement terminates upon the expiration of the
last patent licensed under the agreement unless terminated earlier by either
party 30 days following a default by the other party. Liability for breaches
under the agreement by either party to the other is limited to $17.0 million
with the exception of, in our case, additional money to be paid by us to TRW
under the agreement or a related time and materials agreement.

COMMITMENTS TO PROVIDE CAPITAL

     In February 2000, we received capital commitments of $2.5 million each from
Dynamics Technology, Inc., Advent International Corp., Gemini Investors LLC,
Stratford Equity Partners, L.P., Crossroads Venture Capital, LLC and TRW in the
event that we do not complete an initial public offering with gross proceeds of
$25 million by May 31, 2000. The $15.0 million in commitments, if required, will
be documented in the form of convertible promissory notes bearing interest at a
fixed rate of 10% per annum. If not prepaid, the notes will convert into shares
issued in our next round of equity financing of at least $15.0 million. In
connection with obtaining these commitments, we issued warrants to purchase
10,000 shares of our common stock to each of these six investors at a price of
$4.00 per share and agreed to issue additional warrants for 30,000 shares of our
common stock to each of these six investors at the then fair market value per
share if the loan commitments are exercised, for each $2,500,000 borrowed. These
warrants expire upon the earlier of 5 years or 30 days after the consummation of
an initial public offering.

AGREEMENTS WITH OFFICERS AND DIRECTORS

     On December 10, 1999, Wireless made a full recourse loan to William J.
Palumbo in the amount of $168,750 to fund the exercise of his option to purchase
625,000 shares of common stock. Principal and interest due under this loan is
secured by a lien on the option shares.

     We have an unwritten agreement with William E. Gibson which has been
approved by our board of directors pursuant to which Mr. Gibson is paid $15,000
per month for his services as Chairman of the Board of Directors.

OTHER RELATED PARTY TRANSACTIONS

     We have granted options and issued common stock to our executive officers
and directors. See "Management--Director Compensation" and "Principal
Stockholders."

     Holders of shares of preferred stock and certain holders of warrants for
the issuance of common stock are entitled to registration rights in respect of
the common stock issued or issuable upon conversion or exercise thereof. See
"Description of Capital Stock--Registration Rights."

     We have entered into an indemnification agreement with each of our
executive officers and directors containing provisions that may require us,
among other things, to indemnify our officers and directors against liabilities
that may arise by reason of their status or service as officers or directors
(other than liabilities arising from


                                       58
<PAGE>

willful misconduct of a culpable nature) and to advance expenses incurred as a
result of any proceeding against them as to which they could be indemnified. See
"Management--Limitation of Liability and Indemnification."

     We have entered into non-competition and confidentiality agreements with
some of our officers.

     We believe that all of the transactions set forth above were made on terms
no less favorable to us than could have been otherwise obtained from
unaffiliated third parties. All future transactions, including loans, if any,
between us and our officers, directors and principal stockholders and their
affiliates and any transactions between us and any entity with which our
officers, directors or five percent stockholders are affiliated will be approved

and disinterested outside directors of the board of directors and will be on
terms no less favorable to us than could be obtained from unaffiliated third
parties.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     At the closing of this offering, we will be authorized to issue 100,000,000
shares of common stock, $0.001 par value per share, and 5,000,000 shares of
undesignated preferred stock, $0.001 par value per share, after giving effect to
the amendment of our certificate of incorporation to delete references to the
existing preferred stock following conversion of that stock. The following
description of capital stock gives effect to the certificate of incorporation to
be filed upon closing of this offering. Immediately following the completion of
this offering, and assuming no exercise of the underwriters' over-allotment
option, an aggregate of __________________ shares of common stock will be issued
and outstanding, and no shares of preferred stock will be issued and
outstanding.

     The following description of our capital stock is subject to and qualified
by our certificate of incorporation and bylaws, which are included as exhibits
to the registration statement of which this prospectus forms a part, and by the
provisions of the applicable Delaware law.

COMMON STOCK

     The holders of our common stock are entitled to one vote per share on all
matters to be voted upon by our stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock that may come into existence, the
holders of common stock are entitled to receive ratably those dividends, if any,
as may be declared from time to time by the board of directors out of funds
legally available for dividends. See "Dividend Policy." In the event of our
liquidation, dissolution or winding up, the holders of our common stock are
entitled to share ratably in all assets remaining after payment of liabilities,
subject to prior distribution rights of preferred stock, if any, then
outstanding. Our common stock has no preemptive or conversion rights or other
subscription rights. There are no redemption or sinking fund provisions
applicable to the common stock. All outstanding shares of common stock are fully
paid and non-assessable, and the shares of common stock to be outstanding upon
completion of this offering will be fully paid and non-assessable.

PREFERRED STOCK

     Our board of directors is authorized to issue from time to time, without
stockholder authorization, in one or more designated series, any or all of our
authorized but unissued shares of preferred stock with any dividend, redemption,
conversion and exchange provisions as may be provided in the particular series.
Any series of preferred stock may possess voting, dividend, liquidation and
redemption rights superior to those of the common stock. The rights of the
holders of our 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. Issuance of a new series of preferred stock, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, could have the effect of entrenching our board of directors and making
it more difficult for a third-party to acquire, or discourage a third-party from
acquiring, a majority of our outstanding voting stock. We have no present plans
to issue any shares of or designate any series of preferred stock.

WARRANTS

     As of December 31, 1999, we had outstanding warrants to purchase an
aggregate of 621,122 shares of our common stock on an as-converted basis,
including:

      o Warrants to purchase 362,000 shares of common stock at $0.75 per share
        which will expire on March 31, 2005;

      o Warrants to purchase 30,460 shares of common stock at $1.22 per share
        which will expire on May 5, 2002;

      o Warrants to purchase 48,000 shares of common stock at $1.25 per share,
        which will expire on October 16, 2003;

      o Warrants to purchase 20,662 and 100,000 shares of common stock at $2.50
        per share, which will expire on September 13, 2004 and upon the closing
        of this offering, respectively; and

      o Warrants to purchase 60,000 shares of common stock at $4.00 per share,
        which will expire 30 days after the closing of this offering.


                                       62

CONVERTIBLE PROMISSORY NOTE

     AMT Capital, Ltd. holds a promissory note, dated as of August 17, 1999 in
the principal amount of $1,000,000 which note is convertible into 320,000 shares
of Series E Preferred Stock and upon conversion the holder will receive a
warrant to purchase 32,000 shares of common stock at an exercise price of $0.75
per share.

REGISTRATION RIGHTS

     After this offering, pursuant to the terms of an Investors' Rights
Agreement, holders of 20,509,837 shares of our common stock and 552,500 shares
of our common stock issuable upon the exercise of outstanding warrants will be
entitled to certain registration rights with respect to their capital stock of
Wireless. Under the Investors' Rights Agreement, at any time after the earlier
of (i) January 31, 2001 or (ii) three months after this offering, holders of
more than 30% of these shares may require us to effect registration under the
Securities Act, subject to the board of directors' right, if such registration
would harm us, to defer such registration for up to 60 days. In addition, if we
propose to issue equity securities under the Securities Act for our own account
in an underwritten public offering, then any of the investors has a right
(subject to quantity limitations determined by the underwriters) to request that
we register such investor's registrable securities. Once we qualify to register
the sale of securities on Form S-3, investors proposing to sell an aggregate of
at least $2,000,000 of registrable securities may require us to effect one S-3
registration per year. All registration expenses incurred in connection with any
of the registrations described above will be borne by us. The participating
investors will pay for underwriting discounts and commissions incurred in
connection with any such registrations. We have agreed to indemnify the
investors against certain liabilities including Securities Act liabilities in
connection with any registration effected by us in which their shares are
included pursuant to the Investors' Rights Agreement. Registration of any of the
shares of common stock held by security holders with registration rights would
result in such shares becoming freely tradeable without restriction under the
Securities Act immediately upon effectiveness of such registration. These
registration rights terminate once all shares of our stock may be sold under
Rule 144 during any 90 day period. In addition, holders of 68,662 shares of our
common stock issuable upon the exercise of outstanding warrants will be entitled
to registration rights different from those described above. In particular,
these holders are entitled to include their shares in any registration initiated
by us or by other holders on Forms S-1 or S-3 (excluding registrations relating
to stock plans) without being subject to underwriters' quantity limitations.

COMPLIANCE WITH CALIFORNIA LAW

     We are currently subject to Section 2115 of the California General
Corporation Law. Section 2115 provides that, regardless of a company's legal
domicile, certain provisions of California corporate law will apply to that
company if more than 50% of our outstanding voting securities are held of record
by persons having addresses in California and the majority of the company's
operations occur in California. For example, while we are subject to Section
2115, stockholders may cumulate votes in electing directors. This means that
each stockholder may vote the number of votes equal to the number of candidates
multiplied by the number of votes to which the stockholder's shares are normally
entitled in favor of one candidate. This potentially allows minority
stockholders to elect some members of the board of directors. When we are no
longer subject to Section 2115, cumulative voting will not be allowed and a
holder of 50% or more of our voting stock will be able to control the election
of all directors. In addition to this difference, Section 2115 has the following
additional effects:

     o    enables removal of directors with or without cause with majority
          stockholder approval;

     o    places limitations on the distribution of dividends;

     o    extends additional rights to dissenting stockholders in any
          reorganization, including a merger, sale of assets or exchange of
          shares; and

     o    provides for information rights and required filings in the event we
          effect a sale of assets or complete a merger.

     We anticipate that our common stock will be qualified for trading as a
national market security on the Nasdaq National Market and that we will have at
least 800 stockholders of record by the record date for our 2000 annual meeting
of stockholders. If these two conditions occur, then we will no longer be
subject to Section 2115 as of the record date for our 2000 annual meeting of
stockholders.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS
AND DELAWARE LAW

     Our certificate of incorporation authorizes our board to issue up to
5,000,000 shares of undesignated preferred stock after the offering. Further,
without any further vote or action on the part of our stockholders, our board of
directors will have the authority to determine the rights, preferences,
privileges and restrictions of the undesignated preferred stock. See
"--Preferred Stock." Our certificate of incorporation also provides that all
stockholder action must be effected at a duly called meeting of stockholders and
not by written consent. In addition, our certificate of incorporation and bylaws
do not permit our stockholders to call a special meeting of stockholders. Only
our Chief Executive Officer, President, Chairman of the Board or a majority of
the board of directors are permitted to call a special meeting of stockholders.
Our certificate of incorporation also provides that the board of directors is
divided into three classes, with each director assigned to a class with a term
of three years, and that the number of directors may only be determined by the
board of directors. Our bylaws require that stockholders give advance notice to
our secretary of any nominations for director or other business to be brought by
stockholders at any stockholders' meeting, and that the chairman of the board
has the authority to adjourn any meeting called by the stockholders. Our bylaws
also require a supermajority vote of members of the board of directors and/or
stockholders to amend certain bylaw provisions. These provisions of our restated
certificate of incorporation and our bylaws could discourage potential
acquisition proposals and could delay or prevent a change in control of the
company. These provisions also may have the effect of preventing changes in the
management of the company. See "Risk Factors--Our certificate of incorporation
and bylaws may discourage potential acquisitions of our business by third
parties that stockholders may consider favorable."

     We are subject to Section 203 of the Delaware General Corporation Law, an
anti-takeover law. In general, Section 203 prohibits a Delaware corporation from
engaging in any business combination with any interested stockholder for a
period of three years following the date that the stockholder became an
interested stockholder, unless:

     o    prior to that date, the board of directors of the corporation approved
          either the business combination or the transaction that resulted in
          the stockholder becoming an interested stockholder;

     o    upon consummation of the transaction that resulted in the stockholder
          becoming an interested stockholder, the interested stockholder owned
          at least 85% of the voting stock of the corporation outstanding at the
          time the transaction commenced, excluding for purposes of determining
          the number of shares outstanding those shares owned by:

          o    persons who are directors and also officers; and

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

     o    on or subsequent to that date, the business combination is approved by
          the board of directors of the corporation and authorized at an annual
          or special meeting of stockholders, and not by written consent, by the
          affirmative vote of at least 662/3% of the outstanding voting stock
          that is not owned by the interested stockholder.

     Section 203 defines "business combination" to include the following:

     o    any merger or consolidation involving the corporation and the
          interested stockholder;

     o    any sale, transfer, pledge or other disposition of 10% or more of the
          assets of the corporation involving the interested stockholder;

     o    subject to certain exceptions, any transaction that results in the
          issuance or transfer by the corporation of any stock of the
          corporation to the interested stockholder;

     o    any transaction involving the corporation that has the effect of
          increasing the proportionate share of the stock of any class or series
          of the corporation beneficially owned by the interested stockholder;
          or

     o    the receipt by the interested stockholder of the benefit of any loans,
          advances, guarantees, pledges or other financial benefits provided by
          or through the corporation.

     In general, Section 203 defines an interested stockholder as any entity or
person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by any of these entities or persons.

                            NON-UNITED STATES HOLDERS

     The following is a general discussion of the material U.S. federal
income and estate tax consequences of the ownership and disposition of the
common stock applicable to holders who are not U.S. persons within the
meaning of the Internal Revenue Code.  A U.S. person is any person who is:

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

     o    a corporation, partnership, unless otherwise provided by Treasury
          regulations, or other entity created or organized in the U.S. or under
          the laws of the U.S. or any political subdivision thereof;

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

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

     This discussion does not address all aspects of U.S. federal income and
estate taxation that may be relevant in light of a holder's particular facts and
circumstances, such as being a U.S. expatriate, and does not address any tax
consequences arising under the laws of any state, local or non-U.S. taxing
jurisdiction. Furthermore, the following discussion is based on current
provisions of the Internal Revenue Code of 1986, as amended, and administrative
and judicial interpretations thereof, all as in effect on the date hereof, and
all of which are subject to change, possibly with retroactive effect. We have
not and will not seek a ruling from the Internal Revenue Service with respect to
the U.S. federal income and estate tax consequences described below, and as a
result, there can be no assurance that the Internal Revenue Service will not
disagree with or challenge any of the conclusions set forth in this discussion.
In addition, the Internal Revenue Service is not precluded from adopting a
contrary position.

DIVIDENDS

     Any dividend paid to a holder of common stock who is not a U.S. person
generally will be subject to U.S. withholding tax either at a rate of 30% of the
gross amount of the dividend or such lower rate as may be specified by an
applicable tax treaty. Dividends received by a holder that are effectively
connected with a U.S. trade or business conducted by the holder are exempt from
such withholding tax. However, those effectively connected dividends, net of
certain deductions and credits, are taxed at the same graduated rates applicable
to U.S. persons.

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

     A holder of common stock that is eligible for a reduced rate of withholding
tax pursuant to a tax treaty may obtain a refund of any excess amounts currently
withheld by filing an appropriate claim for refund with the Internal Revenue
Service.

GAIN ON DISPOSITION OF COMMON STOCK

     A holder of common stock who is not a U.S. person generally will not be
subject to U.S. federal income tax on any gain realized upon the sale or
other disposition of his common stock unless:

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

     o    the holder is an individual who holds his or her common stock as a
          capital asset and who is present in the U.S. for a period or periods
          aggregating 183 days or more during the calendar year in which the
          sale or disposition occurs and certain other conditions are met; or

     o    we are or have been a United States real property holding corporation
          within the meaning of the Internal Revenue Code at any time within the
          shorter of the five-year period preceding the disposition or the
          holder's holding period for its common stock. We have determined that
          we are not and do not believe that we will become a United States real
          property holding corporation.


                                       66

BACKUP WITHHOLDING AND INFORMATION REPORTING

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

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

     Under current Treasury Regulations, the payment of the proceeds of the
disposition of common stock to or through the U.S. office of a broker is subject
to information reporting and backup withholding at a rate of 31% unless the
holder certifies its non-U.S. status under penalties of perjury or otherwise
establishes an exemption. Generally, the payment of the proceeds of the
disposition by a holder of common stock who is not a U.S. person outside the
U.S. to or through a foreign office of a broker will not be subject to backup
withholding but will be subject to information reporting requirements if the
broker is a U.S. person, a controlled foreign corporation as defined in the
Internal Revenue Code, or a foreign person 50% or more of whose gross income for
certain periods is from the conduct of a U.S. trade of business, unless the
broker has documentary evidence in its files of the holders' non-U.S. status and
certain other conditions are met, or the holder otherwise establishes an
exemption. Neither backup withholding nor information reporting generally will
apply to a payment of the proceeds of a disposition of common stock by or
through a foreign office of a foreign broker not subject to the preceding
sentence.

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

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

ESTATE TAX

     An individual holder who owns common stock at the time of his death or had
made one or more of certain lifetime transfers of an interest in common stock
will be required to include the value of that common stock in such holder's
gross estate for U.S. federal estate tax purposes, unless an applicable estate
tax treaty provides otherwise.

     THE FOREGOING IS A DISCUSSION OF THE MATERIAL U.S. FEDERAL INCOME AND
ESTATE TAX CONSEQUENCES OF THE OWNERSHIP, SALE OR OTHER DISPOSITION OF COMMON
STOCK BY HOLDERS WHO ARE NOT U.S. PERSONS WITHIN THE MEANING OF THE INTERNAL
REVENUE CODE. ACCORDINGLY, INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
WITH RESPECT TO THE INCOME TAX CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF
COMMON STOCK, INCLUDING THE APPLICATION AND EFFECT OF THE LAWS OF ANY STATE,
LOCAL, FOREIGN OR OTHER TAXING JURISDICTION.

                        SHARES AVAILABLE FOR FUTURE SALE

     Prior to this offering, there has been no public market for our common
stock, and we cannot predict the effect, if any, that market sales of shares of
our common stock or the availability of shares of our common stock for sale will
have on the market price of common stock prevailing from time to time.
Nevertheless, sales of substantial amounts of our common stock in the public
market could adversely affect the market price of our common stock and could
impair our future ability to raise capital through the sale of our equity
securities.

     Upon the completion of this offering we will have ________________ shares
of common stock outstanding assuming no exercise of the underwriters
over-allotment option. The number of shares of common stock to be outstanding
after this offering is based on the number of shares outstanding as of December
31, 1999, and excludes:

     o    1,706,047 shares of common stock issuable upon the exercise of stock
          options outstanding as of December 31, 1999 at a weighted average
          exercise price of $0.53 per share;

     o    392,460 shares of common stock issuable upon the exercise of
          outstanding warrants as of December 31, 1999 at a weighted average
          exercise price of $0.79 per share;

     o    330,592 shares of common stock issuable upon conversion of an
          outstanding convertible promissory note, as of December 31, 1999;

     o    8,750,000 shares of common stock reserved for issuance under our 2000
          Stock Incentive Plan that incorporates our 1998 Stock Plan; and

     o    250,000 shares of common stock reserved for issuance under our 2000
          Employee Stock Purchase Plan.

Of the outstanding shares, all of the shares sold in this offering will be
freely tradable, except that any shares held by our "affiliates," as that term
is defined in Rule 144 promulgated under the Securities Act, may only be sold in
compliance with the limitations described below. The remaining            shares
of common stock will be deemed "restricted securities" as defined under Rule
144. Restricted shares may be sold in the public market only if registered or if
they qualify for an exemption from registration under Rules 144, 144(k) or 701
promulgated under the Securities Act, which rules are summarized below. Subject
to the lock-up agreements described below and the provisions of Rules 144,
144(k) and 701, additional shares will be available for sale in the public
market as follows:

   SHARES                                     DATE
- --------------  ----------------------------------------------------------------
                 After the date of this prospectus, freely tradable shares sold
                 in this offering and shares saleable under Rule 144(k) that are
                 not subject to the 180-day lock-up

                 After 180 days from the date of this prospectus, the 180-day
                 lock-up is released and these shares are saleable under Rule
                 144 (subject, in some cases, to volume limitations) or Rule
                 144(k)

                 After 180 days from the date of this prospectus, the 180-day
                 lock-up is released and these shares are saleable under Rule
                 701 (subject to repurchase by the Company)

                 After 180 days from the date of this prospectus, restricted
                 securities that are held for less than one year and are not yet
                 saleable under Rule 144

RULE 144

     In general, under Rule 144 as currently in effect, a person, or group of
persons whose shares are required to be aggregated, including any of our
affiliates, who has beneficially owned shares for at least one year, including
the holding period of any prior owner who is not an affiliate, is entitled to
sell within any three-month period commencing 90 days after the date of this
prospectus, a number of shares that does not exceed the greater of one percent
of the then-outstanding shares of our common stock, which will be approximately
__________________ shares immediately after this offering, or the average weekly
trading volume in our common stock during the four calendar weeks preceding the
date on which notice of such sale is filed, subject to certain restrictions. In
addition, a person who is not deemed to have been an affiliate at any time
during the 90 days preceding a sale and who has beneficially owned the shares
proposed to be sold for at least two years, including the holding period of any
prior owner who is not an affiliate, would be entitled to sell these shares
under Rule 144(k) without regard to the requirements described


                                       68
<PAGE>

above, unless otherwise contractually restricted. To the extent that shares were
acquired from one of our affiliates, a person's holding period for the purpose
of effecting a sale under Rule 144 would commence on the date of transfer from
the affiliate.

STOCK OPTIONS

     As of December 31, 1999, options to purchase a total of 1,706,047 shares of
common stock were outstanding, all of which were currently exercisable. 664,190
of the shares issuable upon exercise of these options were vested. We intend to
file a Form S-8 registration statement under the Securities Act to register all
shares of common stock issuable under our 2000 Stock Incentive Plan and our 2000
Employee Stock Purchase Plan. Accordingly, shares of common stock underlying
these options will be eligible for sale in the public markets, subject to
vesting restrictions or the lock-up agreements described below. See "Executive
Compensation and other information--Employee Benefit Plans."

     In general, under Rule 701 of the Securities Act of 1933 as currently in
effect, each of our employees, consultants or advisors who purchases shares from
us in connection with a compensatory stock plan or other written agreement is
eligible to resell such shares 90 days after the date of this prospectus in
reliance on Rule 144, but without compliance with certain restrictions,
including the holding period, contained in Rule 144.

LOCK-UP AGREEMENTS

     We have agreed, and each of our officers and directors and substantially
all of our securityholders have agreed, subject to specified exceptions, not to,
without the prior written consent of Salomon Smith Barney Inc., sell, otherwise
dispose of any shares of our common stock or options to acquire shares of our
common stock or take any action to do any of the foregoing during the 180-day
period following the date of this prospectus. Salomon Smith Barney Inc. may, in
its sole discretion and at any time without notice, release all or any portion
of the securities subject to lock-up agreements.  See "Underwriting."

REGISTRATION RIGHTS

     Following this offering, under specified circumstances and subject to
customary conditions, holders of approximately 20,509,837 shares of our
outstanding common stock and warrants to purchase up to 552,500 shares of our
common stock will have demand registration rights with respect to their shares
of common stock, subject to the 180-day lock-up arrangement described above, to
require us to register their shares of common stock under the Securities Act,
and rights to participate in any future registrations of our securities. Holders
of an additional 68,662 shares of our common stock issuable upon exercise of
outstanding warrants will be entitled to participate in any future registrations
of our securities without being subject to underwriters' quantity limitations,
but will not possess demand registration rights. If the holders of these
registrable securities request that we register their shares, and if the
registration is effected, these shares will become freely tradable without
restriction under the Securities Act. Any sales of securities by these
stockholders could have a material adverse effect on the trading price of our
common stock. See "Description of Capital Stock--Registration Rights."

     Subject to the terms and conditions stated in the underwriting agreement,
each underwriter named below has severally agreed to purchase, and we have
agreed to sell to such underwriter, the number of shares set forth opposite the
name of such underwriter.

                                                           ====================

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

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

     We have granted the underwriters a 30-day option to purchase up to an
additional            shares to cover over-allotments, if any. The underwriters
may exercise such option solely for the purpose of covering over-allotments, if
any, in connection with this offering. To the extent such option is exercised,
each underwriter will be obligated, subject to the conditions stated above, to
purchase a number of additional shares approximately proportionate to such
underwriter's initial purchase commitment.

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

     The underwriters have reserved for sale, at the initial public offering
price, up to            common shares for customers, directors, employees and
other persons associated with us who have expressed an interest in purchasing
common shares in the offering. The number of shares available for sale to the
general public in the offering will be reduced to the extent these persons
purchase these reserved shares. Any reserved shares not so purchased will be
offered by the underwriters to the general public on the same terms as the other
shares.

     Prior to this offering, there has been no public market for our common
stock. Consequently, the initial public offering price for our shares was
determined by negotiations among us and the representatives. Among the factors
considered in determining the initial public offering price were our record of
operations, our current financial condition, our future prospects, our markets,
the economic conditions in and future prospects for the industry in which we
compete, our management, and currently prevailing general conditions in the
equity securities markets, including current market valuations of publicly
traded companies considered comparable to us. There can be no


                                       70
<PAGE>

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

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

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

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

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

     Any of these activities may cause the price of the common stock to be
higher than the price that otherwise would exist in the open market in the
absence of such transactions. These transactions may be effected on the Nasdaq
National Market or in the over-the-counter market, or otherwise and, if
commenced, may be discontinued at any time.

     We estimate that the total expenses, excluding underwriting discounts and
commissions, of this offering will be approximately $          .

     We have agreed to indemnify the underwriters against liabilities to which
they may become subject, including liabilities that may arise under the
Securities Act of 1933, the Securities Exchange Act of 1934 or other federal or
state statutory law or regulation, at common law or otherwise or to contribute
to payments the underwriters may be required to make in respect of any of those
liabilities.

following report.

                                                          /s/ KPMG LLP



The Board of Directors
Wireless, Inc.:

We have audited the accompanying balance sheets of Wireless, Inc. as of December
31, 1998 and 1999, and the related statements of operations, stockholders'
equity, and cash flows for the period from May 7, 1997 (inception) to December
31, 1997 and the years ended December 31, 1998 and 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Wireless, Inc. as of December
31, 1998 and 1999, and the results of their operations and their cash flows for
the period from May 7, 1997 (inception) to December 31, 1997 and the years ended
December 31, 1998 and 1999 in conformity with generally accepted accounting
principles.

                                 WIRELESS, INC.
                          NOTES TO FINANCIAL STATEMENTS

(1)    THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       (a)   THE COMPANY

             Wireless, Inc. (the Company) was incorporated in California on May
             7, 1997 to develop broadband wireless access solutions that enable
             Internet and communication service providers, telephone operating
             companies and private network operators to deliver voice and
             high-speed data services to their customers. The operations of the
             Company include the design, manufacture and marketing of
             high-speed, wireless, point-to-point and point-to-multipoint
             telecommunications access equipment. The Company's products are
             distributed through a network of worldwide independent
             distributors, system integrators, local resellers and a direct
             sales force.

       (b)   REVENUE RECOGNITION

             Revenue on products is recognized when all of the following have
             occurred: the product has been shipped; title and risk of loss have
             passed to the customer; the Company has the right to invoice the
             customer and collection of the receivable is probable; and all
             obligations have been fulfilled. The only post-sale obligation is a
             12 month warranty. Revenue from services is recognized when the
             service is completed. Trial sales made directly to the end users
             are not recognized as revenue until the trial has been completed
             and the product has been accepted.

             Estimated warranty costs are accrued at the time of the sale based
             upon the Company's historical experience.

       (c)   USE OF ESTIMATES

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

       (d)   PROPERTY AND EQUIPMENT

             Property and equipment are stated at cost. Equipment under capital
             leases is stated at the present value of minimum lease payments at
             the inception of the lease. Depreciation and amortization of
             property and equipment is provided using the straight-line method
             over the estimated useful lives of the respective assets, which
             range from three to five years. Equipment held under capital leases
             is amortized using the straight-line method over the shorter of the
             lease term or the estimated useful life of the asset.

       (e)   INTANGIBLE ASSETS

             Intangible assets include developed technology, assembled
             workforce, core technology and goodwill all related to the
             acquisition of Multipoint Networks, Inc. as discussed in notes 3
             and 4. Intangibles are amortized on a straight line basis over
             their estimated useful lives which range from two to five years.

       (f)   CASH AND CASH EQUIVALENTS

             The Company considers all highly liquid investments with remaining
             maturities of three months or less at the date of acquisition to be
             cash equivalents.

             Restricted cash consists of amounts held as security for an
             outstanding letter of credit.

                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

       (g)   CONCENTRATION OF RISK

             Financial instruments, which potentially subject the Company to a
             concentration of credit risk, principally consist of accounts
             receivable. The Company performs ongoing credit evaluations of its
             customers and generally does not require collateral on accounts
             receivable.

             The following table summarizes information relating to the
             Company's significant customers with revenues comprising greater
             than 10% of total revenue for the period and/or balances greater
             than 10% of accounts receivable at year end:

</TABLE>

- -----------------
* Revenue and/or accounts receivable accounted for less than 10% in these years.

       (h)   FAIR VALUE OF FINANCIAL INSTRUMENTS

             The fair value of the Company's cash, accounts receivable, accounts
             payable, and borrowings approximate their carrying values due to
             their short maturity or variable-rate structure. The interest rates
             on the capital lease obligations are deemed to be at market rates
             and the carrying amounts approximate fair value.

       (i)   RESEARCH AND DEVELOPMENT

             Costs incurred in the research and development of new products and
             enhancements to existing products are expensed as incurred until
             the technological feasibility of the product or enhancement has
             been established. Technological feasibility is established when a
             product design and a working model have been completed and the
             completeness of the working model, and its consistency with the
             product design, have been confirmed by testing. After establishing
             technological feasibility, material development costs are
             capitalized. The capitalized cost is then amortized on a
             straight-line basis over the estimated product life, or is
             amortized based on the ratio of current revenues to total projected
             product revenues, whichever is greater. To date, the period between
             completion of a working model and the general release of the
             product has been short and development costs qualifying for
             capitalization have been insignificant. Accordingly, the Company
             has not capitalized any development costs.

       (j)   INVENTORY

             Inventory is stated at the lower of cost, determined on a first-in
             first-out basis or net realizable value.

       (k)   INCOME TAXES

             The Company utilizes the asset and liability method of accounting
             for income taxes. Under this method, deferred tax assets and
             liabilities are determined based on the difference between the
             financial statement and tax basis of assets and liabilities using
             enacted tax rates in effect for the year in which the differences
             are expected to affect taxable income. Valuation allowances are
             established when necessary to reduce deferred tax assets to the
             amounts expected to be recovered.

<PAGE>

                                 WIRELESS, INC.
                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

       (l)   STOCK-BASED COMPENSATION

             The Company has adopted Statement of Financial Accounting Standards
             (SFAS) No. 123, ACCOUNTING FOR STOCK BASED COMPENSATION. This
             statement establishes financial accounting and reporting standards
             for stock based compensation, including employee stock option
             plans. As allowed by SFAS 123, the Company measures compensation
             expense under the provisions of Accounting Principles Board (APB)
             Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES (APB 25),
             and related interpretations. The Company follows Financial
             Accounting Standards Board Interpretation No. 28, ACCOUNTING FOR
             STOCK APPRECIATION RIGHTS AND OTHER VARIABLE STOCK OPTION OR AWARD
             PLANS in amortizing unearned compensation during the service
             period.

       (m)   COMPREHENSIVE INCOME

             The Company does not have any components of comprehensive income,
             consequently comprehensive loss consists entirely of net loss for
             all periods presented.

       (n)   LONG-LIVED ASSETS, INCLUDING INTANGIBLE ASSETS

             The Company accounts for long-lived assets under SFAS No. 121,
             ACCOUNTING FOR IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED
             ASSETS TO BE DISPOSED OF. SFAS No. 121 requires that long-lived
             assets and certain identifiable intangibles be reviewed for
             impairment whenever events or changes in circumstances indicate
             that the carrying amount of assets may not be recoverable.
             Recoverability of assets to be held and used is measured by a
             comparison of the carrying amount of an asset to future net cash
             flows expected to be generated by the asset. If such assets are
             considered to be impaired, the impairment loss to be recognized is
             measured by the amount by which the carrying amount of the assets
             exceeds the fair value of the assets. Assets to be disposed of are
             reported at the lower of the carrying amount or fair value less
             costs to sell. The Company estimates fair value based on the best
             information available, making judgments and projections as
             considered necessary.

       (o)   ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

             In June 1998, the FASB issued SFAS No. 133, ACCOUNTING FOR
             DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. SFAS No. 133
             establishes accounting and reporting standards for derivative
             instruments, including certain derivative instruments embedded in
             other contracts, (collectively referred to as derivatives) and for
             hedging activities. It requires that an entity recognize all
             derivatives as either assets or liabilities in the statement of
             financial position and measure those instruments at fair value. For
             a derivative not designated as a hedging instrument, changes in the
             fair value of the derivative are recognized in earnings in the
             period of change. This statement will be effective for all annual
             and interim periods beginning after January 1, 2001. Management
             does not believe the adoption of SFAS No. 133 will have a material
             effect on the Company's consolidated financial position or results
             of operations.

       (p)   NET LOSS PER SHARE

             Net loss per share is computed based on SFAS No. 128, EARNINGS PER
             SHARE. The basic net loss per share is computed by dividing the net
             loss attributable to common stockholders by the weighted average
             number of common shares outstanding. Potential weighted average
             common shares relating to stock options of 63,000, 214,000 and
             845,000 in 1997, 1998 and 1999, respectively, potential weighted
             average common shares relating to convertible preferred stock of
             6,243,000, 5,858,000 and 13,115,000 shares in 1997, 1998 and 1999,
             respectively, and weighted average unvested restricted shares of
             405,000, 531,000 and 735,000 shares in 1997, 1998 and 1999
             respectively, have also been excluded from the calculations of net
             loss per share as their impact would be anti-dilutive. Thus, the
             diluted net loss per share in these years is the same as the basic
             net loss per share. Net loss per share is not presented in the
             period from May 7, 1997 (inception) to December 31, 1997 as all
             common share as of December 31, 1997 were unvested and subject to
             repurchase and accordingly are not considered outstanding for the
             computations of net loss per share.

       (q)   PRO FORMA NET LOSS PER SHARE (UNAUDITED)

             Unaudited pro forma basic and diluted net loss per share was $0.84
             for the year ended December 31, 1999 based on pro forma
             weighted-average shares outstanding of 16,302,544 for the year.
             This information reflects per share data assuming the conversion of
             all outstanding shares of convertible preferred stock at the
             respective conversion rate for each preferred share of Series A, B,
             C, D and E as if the conversion of the preferred stock had taken
             place at January 1, 1999 or at the date of issuance, if later. Pro
             forma common equivalent shares, comprised of incremental common
             shares issuable upon exercise of stock options and warrants are not
             included in pro forma diluted net loss per share because they would
             be antidilutive.

       (r)   PRO FORMA STOCKHOLDERS' EQUITY (UNAUDITED)

             The unaudited pro forma stockholders' equity gives effect to (1)
             the issuance of 3,000,000 shares of Series F convertible preferred
             stock and 3,429,352 common shares, at $5 per share, in January
             2000, (2) the exercise of warrants to purchase 48,000 shares of
             Series D convertible preferred stock at $1.25 per share and 20,000
             shares of Series E convertible preferred stock at $2.50 per share
             and (3) the exercise of warrants to purchase 160,000 shares of
             common stock at an average exercise price of $3.06, prior to the
             consummation of the Company's initial public offering. It also
             gives effect to the conversion of Series A, B, C, D, E, and F
             convertible preferred stock expected to be outstanding at the
             consummation of the Company's initial public offering, into
             20,578,499 shares of common stock, upon the closing of the
             Company's initial public offering.

       technology agreement. For the year ended December 31, 1997, the Company
       recorded an impairment charge of $1,500,000 related to the acquired
       technology.

(4)    MULTIPOINT NETWORKS, INC. ACQUISITION

       On August 26, 1998 Wireless, Inc. acquired the net assets of Multipoint
       Networks, Inc. (Multipoint). Multipoint was incorporated in California in
       1987 and designed, manufactured and marketed wireless metropolitan-area
       data network products based on unique patented digital transceiver
       technology. The acquisition has been accounted for by the purchase method
       and accordingly, the operating results of Multipoint form part of the
       operating results of the Company from August 26, 1998.

       The $7,253,312 purchase price for the acquisition was comprised as
       follows:

          Issuance of Series C preferred stock...............      $2,855,333
          Issuance of common stock...........................       3,481,198

       There were no contingent payments or other commitments specified in the
       acquisition agreement.

       The purchase price was more than the fair value of the net assets
       acquired of $6,915,079 resulting in goodwill of $338,233. This goodwill
       is included as a component of intangibles and is being amortized over its
       useful life of five years.

       The purchase price was allocated as follows:

           Cash and cash equivalents........................   $    237,781

       In-process research and development was fully expensed upon acquisition
       as the Company determined that the acquired technology had not yet
       achieved technological feasibility and that the technology did not have
       an alternative future use. The in-process research and development
       related to Multipoint's WaveNet IP technology. The valuation of the
       in-process research and development was based upon present value of
       forecasted operating cash flows expected to be generated from the
       technology and considered that the technology was approximately 85%
       complete as of the acquisition date. Developed and core technology are
       being amortized on a straight-line basis over five years. Assembled
       workforce is being amortized on a straight line basis over two years.

(5)    BORROWINGS

       (a)   LINE OF CREDIT

             The Company had available a line of credit which allowed for
             borrowings up to 80% of eligible accounts receivable with a maximum
             borrowing of $2,000,000. The line is renewable annually at the
             option of the bank and the Company. In consideration for the
             renewal in 1999, the Company issued the bank a warrant to purchase
             48,000 shares of the Series D Convertible Stock at $1.25 per share.
             The warrant value of $37,400 is being amortized as interest expense
             over the term of the line of credit. The amount of $37,400 ascribed
             to the warrants was estimated using the Black-Scholes option
             valuation model with the following assumptions: no expected
             dividend yield; risk free interest rate of 5.5%; expected
             volatility of 70%; and contractual term of 5 years. The line is
             secured by substantially all of the Company's assets. Borrowings
             under the line of credit bear interest at 2.5% above the bank's
             prime rate. At December 31, 1999, no borrowings were outstanding on
             the line of credit.

             The line of credit was renewed on February 23, 2000 with the credit
             limit increased to $5 million in the event that the Company
             receives at least $15 million in net cash proceeds from the issue
             of equity or subordinated debt, or in the event that the Company
             raises at least $50 million in net cash proceeds from the
             consummation of the initial public offering before May 31, 2000.
             The terms of the line of credit remain unchanged with exception of
             an additional requirement for the Company to maintain tangible net
             worth of $15 million. The Company is committed to issue a five year
             warrant to purchase 37,500 shares of common stock at $4.00 per
             share in the event that the initial public offering is not
             consummated by May 31, 2000 or in the event that the offering does
             not raise net cash proceeds of at least $50 million.

       (b)   CONVERTIBLE NOTES PAYABLE

             During 1998, the Company assumed $1,950,000 of short-term financing
             as part of the acquisition of Multipoint and obtained $2,004,400
             from existing Wireless shareholders in exchange for convertible
             notes payable. The bridge loans carried an interest rate of 10%.
             The convertible notes stated that the outstanding principal and
             interest would be convertible at the option of the holder into
             shares of the Company's equity at the closing of the Company's next
             equity financing. The conversion price was to be determined at the
             time of the next equity financing and was to be consistent with the
             price and terms of that financing.

                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

             On May 21, 1999, the notes and related accrued interest were
             converted to Series D preferred stock at a price of $1.25 per
             share.

             In August 1999, the Company borrowed $1,000,000 under a convertible
             promissory note. The principal amount, together with interest
             accrued at 10% per annum, will become due and payable on September
             1, 2004. At the option of the holder, the note may be converted
             into shares of the next series of the Company's preferred stock at
             a conversion price based on the underlying terms of that financing.
             In September 1999, the Company issued Series E Convertible
             Preferred stock at $2.50 per share with an attached 10% warrant to
             purchase common stock at $0.75 per share. This financing qualified
             as the next financing in accordance with the terms of the
             promissory note. Based on this financing, the promissory note is
             convertible into 320,000 shares of Series E Convertible Preferred
             Stock at $3.125 per share and, if converted, the holder will
             receive a warrant to purchase 32,000 shares of common stock at
             $0.75 per share. These Series E preferred shares will be
             convertible at any time into common shares at a rate of 1.0331
             common shares for each preferred share.

       (c)   BANK LOAN

             In 1999, the Company borrowed $1,000,000 at an interest rate of
             prime plus 3%. As additional consideration, the Company issued the
             bank a warrant to purchase 20,000 shares of Series E Convertible
             Preferred Stock at $2.50 per share. The warrant is valued at
             $27,800 and has been recorded as interest expense. The amount of
             $27,800 ascribed to the warrants was estimated using the
             Black-Scholes option pricing model with the following assumptions:
             no expected dividend yield; risk free interest rate of 5.5%;
             expected volatility of 70%; and contractual term of 5 years. All
             principal and interest was repaid from proceeds of the Series E
             financing.

       (d)   LETTERS OF CREDIT

             The Company has letters of credit outstanding in lieu of security
             deposits on leased facilities. Letters of credit outstanding were
             $80,000 and $302,000 at December 31, 1998 and 1999, respectively.

(6)    STOCKHOLDERS' EQUITY

       (a)   CONVERTIBLE PREFERRED STOCK

             The Company designated and issued convertible preferred stock as
             follows:

             In May 1997, the Company issued 6,000,000 shares of Series A
             Preferred at $0.50 per share of which 3,000,000 shares were issued
             for cash and 3,000,000 shares were issued in exchange for a
             technology license agreement. In 1998, as a result of a subsequent
             restructuring of the license agreement and cancellation of a note
             receivable, 1,700,000 shares were returned to the Company.

             In October 1997, the Company issued 750,000 shares of Series B
             Preferred Stock for $2.00 per share.

             In August 1998, the Company issued 2,146,868 shares of Series C
             Preferred Stock at $1.33 per share in connection with the
             acquisition of Multipoint.

             In March 1999, the Company issued 6,541,013 shares of Series D
             Preferred Stock for $1.25 per share.

             In September 1999, the Company issued 3,600,000 shares of Series E
             Preferred Stock for $2.50 per share and warrants to purchase
             360,000 shares of common stock at $0.75 per share. The conversion
             price was subsequently reduced to $2.42 per share pursuant to a
             resolution by the board of directors on December 21, 1999. The net
             proceeds were allocated to the preferred shares and the warrants
             based on their respective fair values. The warrants were valued at
             $691,200 which is recorded as additional paid in capital. The
             warrants expire 5.5 years from the date of issue. The amount of
             $691,200 ascribed to the warrants was estimated using the
             Black-Scholes option pricing model with the following assumptions:
             no expected dividend yield; risk free interest rate of 6.0%;
             expected volatility of 70%; and contractual term of 5.5 years.

                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

             The rights, preferences, and privileges of the holders of Series A,
             B, C, D, and E preferred stock are as follows:

                  The holders of Series A and B preferred stock are entitled to
                  receive dividends in an amount equivalent to that which they
                  would receive if their shares were converted to common stock.
                  The holders of Series C, D and E preferred stock are entitled
                  to receive preferential dividends at a rate of $0.12, $0.11
                  and $0.23 per share, respectively. All dividends require board
                  of director approval and are noncumulative. The conversion
                  price is the original issue price subject to adjustments for
                  dilution in the event that there is a stock split, subdivision
                  or combination of the outstanding shares of common stock. In
                  addition the conversion price is subject to adjustment in the
                  event that securities are subsequently sold at a lower price,
                  subject to certain exceptions. No dividends are paid or set
                  aside for holders of common stock until all dividends have
                  been paid or set aside for holders of Series A, B, C, D and E
                  preferred stock. No dividends have been declared to date.

                  Shares of Series A, B, C, D, and E preferred stock have a
                  liquidation preference of $0.50, $2.00, $1.33, $1.25 and $2.50
                  per share, respectively, plus any declared but unpaid
                  dividends.

                  Each holder of preferred stock has voting rights equal to
                  common stock on an "as if converted" basis.

                  Each share of preferred stock is convertible at any time into
                  one share of common stock at the option of the holder with the
                  exception of Series B, C and which each share converts into
                  1.1078, 1.0153 and 1.0331 shares of common stock. All shares
                  of preferred stock automatically convert upon the closing of
                  the sale of the Company's common stock in a public offering in
                  which gross proceeds exceed $25,000,000 and the offering price
                  equals or exceeds $7.50 per share. Each series of preferred
                  stock also converts upon the written consent of a specified
                  majority of the holders of such series into common stock.

       (b)   WARRANTS

             As of December 31, 1999, there were warrants outstanding to
             purchase 492,460 shares of common stock at a weighted average
             exercise price of $2.34 per share, 48,000 shares of Series D
             preferred stock at $1.25 per share, and 20,000 shares of Series E
             preferred stock at $2.50 per share. The warrants contain provisions
             for the adjustment of the exercise price and the aggregate number
             of shares issuable upon the exercise of the warrant under certain
             circumstances, including stock dividends, stock splits,
             reorganizations, consolidations and certain dilutive issuances of
             securities at prices below the then existing warrant exercise
             price.

             In November 1999, the Company issued warrants to purchase 100,000
             common shares for $2.50 per share for fees related to the Series F
             Convertible Preferred Stock financing that is discussed in note 11.
             The warrants are valued at $302,000 which is recorded as a deferred
             financing fee at December 31, 1999. The amount of $302,000 ascribed
             to the warrants was estimated using the Black-Scholes option
             pricing model with the following assumptions: no expected dividend
             yield; risk free interest rate of 5.5%; expected volatility of 70%;
             and contractual term of 3 years.

       (c)   COMMON STOCK

             The Company is authorized to issue 50,000,000 shares of common
             stock.

             During 1997, 1998 and 1999 the Company issued 599,500, 229,750 and
             4,387,085 shares of common stock upon the exercise of stock options
             granted under the Company's 1997 Incentive Stock Option Plan.
             Shares issued under the Plan are subject to repurchase until they
             are fully vested.

             Of the 1999 stock option exercises, 625,000 shares were issued to
             an officer of the Company in exchange for a promissory note that is
             secured by the shares. The recourse promissory note bears interest
             at 6.39% per year and is due on December 10, 2009.

                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

       (d)   1997 STOCK PLAN

             Pursuant to approval by the Board of Directors (the Board),
             effective June 11, 1997 the Company adopted the 1997 Stock Plan
             (the 1997 Plan) which allowed for the issuance of up to 1,500,000
             shares of common stock. The 1997 plan has subsequently been
             amended, increasing the authorized number of shares to 3,650,000
             and 7,450,000 at December 31, 1998 and 1999. The 1997 Plan will
             terminate on June 11, 2007, or an earlier date when all of the
             shares of common stock set aside for issuance under the 1997 Plan
             have been issued, or when there has been a merger, sale, transfer,
             or other disposition of all or substantially all of the Company's
             assets in a liquidation or dissolution of the Company.

             At the Board's discretion, employees, directors, and consultants
             may be granted options that allow for the purchase of shares of the
             Company's common stock, or they may be issued common stock
             directly, either through the immediate purchase of such shares, or
             as a bonus for services rendered to the Company.

             Both non-statutory and incentive options may be granted under the
             1997 Plan. Incentive options are options which satisfy the
             requirements of Section 422 of the Internal Revenue Code of 1986,
             as amended. Non-statutory options do not satisfy these
             requirements. Non-statutory options may be granted to employees,
             directors, and consultants at a price not less than 85% of the fair
             market value of common stock on the date the option is granted, or
             110% of the fair market value of common stock where the options are
             granted to those individuals owning more than 10% of the total
             combined voting power of all classes of stock of the Company (a 10%
             shareholder). Incentive options may only be granted to employees at
             a price not less than 100% of the fair market value of common stock
             on the date the option is granted.

             Direct issues of shares of the Company's common stock may be
             granted to employees, directors, and consultants at a price not
             less than 85% of the fair market value of common stock on the date
             of grant, or 110% of the fair market value of common stock where
             the shares are granted to a 10% shareholder.

             Vesting schedules may vary at the Board's discretion however, no
             option shall have a term in excess of ten years from the date of
             grant, except where incentive options are granted to a 10%
             shareholder, then the option term shall not exceed five years.
             Shares of common stock issued to employees must vest at a rate of
             at least 20% per year from the date of issuance. Stock options are
             immediately exercisable for all of the option shares. The Company
             has the right to repurchase, at the exercise price paid per share,
             any shares purchased under the option which are not vested. Shares
             subject to repurchase at December 31, 1999 are 2,348,380.

             The Company has reserved 7,450,000 common shares for issuance under
             the 1997 Plan. A summary of the Company's share option plan
             activity is as follows:

             At the time of grant, all stock options were granted at the then
             determined fair value. In consideration of the Company's proposed
             initial public offering, the Company re-evaluated all option grants
             and determined that all stock options had been granted when the
             fair value of the underlying common stock on the grant date had
             exceeded the exercise price of the stock option. During fiscal
             1997, 1998 and 1999, the Company granted options with a
             weighted-average exercise price of $0.08, $0.26 and $0.42,
             respectively, compared to the weighted-average fair value of
             approximately $0.19, $1.07 and $2.31 for the same periods.

             The following table summarizes information about stock options
             outstanding and exercisable under the 1997 Plan as of December 31,
             1999:

            =============  ============  ==========  ============ ==========

             At December 31, 1999, options available for grant under the 1997
             Plan were 828,000.

             A portion of the Company's shares of common stock was not qualified
             or exempted under applicable state securities laws and so a portion
             of the stock option grants may be in violation of those laws. If it
             is determined that the issuance of the affected options constitutes
             a violation of state securities laws, certain shareholders may have
             the right to recover from the Company any consideration paid for
             those shares which were not qualified or exempted under applicable
             state securities laws. The outcome of this matter has not yet been
             determined, however any potential liability is not expected to
             exceed $275,000 in the aggregate.

       (e)   ACCOUNTING FOR STOCK-BASED COMPENSATION

             The Company uses the intrinsic value method to account for its
             option plan. Deferred stock-based compensation cost has been
             recognized for stock option grants to employees when the fair value
             of the underlying common stock on the grant date, or other
             measurement date, exceeds the exercise price of each stock option.
             Deferred stock-based compensation is amortized using the
             accelerated method set for in Financial Accounting Standards Board
             Interpretation No. 28.

             fair value approach to account for its employee stock-based
             compensation plan. Had compensation cost for the Company's plans
             been determined consistently with the fair value approach described
             in SFAS 123, the Company's pro forma net loss and pro forma net

             contract manufacturers to be delivered within the next 120 days
             covered by forecasts. As of December 31, 1999, the Company has
             committed to make purchases totaling $5 million from these
             manufacturers. In some instances, the Company issues
             blanket purchase orders for specific quantities and delivery
             schedules over 12 to 18 months to obtain price discounts. If the
             Company cancels the purchase order before its term, it would be
             obligated for the difference between the regular price and the
             discounted price plus the cost of components bought by the
             manufacturer specifically for the Company's products. Based on
             current sales projections, the Company does not believe that they
             will incur any material obligations under these purchase orders.

(10)   GEOGRAPHIC SEGMENT INFORMATION

       The Company adopted SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN
       ENTERPRISE AND RELATED INFORMATION. SFAS No. 131 establishes standards
       for the manner in which public companies report information about
       operating segments in annual and interim financial statements. It also
       establishes standards for related disclosures about products and
       services, geographic areas, and major customers. The method for
       determining what information to report is based on the way management
       organizes the operating segments within the Company for making operating
       decisions and assessing financial performance. The Company's chief
       operating decision-maker is considered to be the chief executive officer
       (CEO). The financial information that the CEO reviews is identical to the
       information presented in the accompanying statements of operations.
       Therefore, the Company has determined that it operates in a single
       operating segment: manufacturing and sale of broadband wireless access
       equipment.

(11)   SUBSEQUENT EVENTS (UNAUDITED)

       (a)   SERIES F PREFERRED STOCK FINANCING--ISSUANCE OF COMMON SHARES AND
             TECHNOLOGY LICENSE AGREEMENT

             In January 2000, the Company completed an offering of 3,000,000
             shares of Series F Preferred Stock for $5.00 per share, for
             $15,000,000 in gross proceeds. TRW, Inc. (TRW) purchased 2,300,000
             shares of the Series F preferred stock financing.

             In January 2000, the Company issued 3,429,352 shares of common
             stock valued at $5.00 per share to TRW in exchange for a
             technology license agreement. Under the agreement, the Company
             purchased and obtained an exclusive royalty-free worldwide
             license in a point-to-multipoint wireless networking technology.
             Any products developed by the Company based on such technology
             may only be sold with base stations configured for outdoor use.
             Sales of products containing the technology with base stations
             configured for indoor use or sales to the U.S. government,
             including organizations in which the U.S. is a member, must be
             made through the owner of the technology (TRW) or its licensees.
             The agreement provides TRW with a royalty-free worldwide
             non-exclusive license in any improvements made by the Company
             upon the technology for the manufacture and sale of products to
             the U.S. Government. If the Company does not offer a commercial
             version of a product containing the technology for sale by July
             2001, unless the delay is the fault of TRW or attributable to
             certain specified reasons, the Company will lose the exclusive
             license.

             Additionally, in consideration of the rights and licenses provided
             under the agreement and the technical assistance to be provided by
             TRW, the Company has agreed to pay TRW 10% of the net proceeds of
             the initial public offering or any private placement of equity
             occurring on or before October 14, 2000, until the Company has paid
             TRW an aggregate of $2.5 million. The balance of this amount is due
             on January 1, 2001, if it has not previously been paid.

                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

       (b)  2000 STOCK INCENTIVE PLAN

             On January 18, 2000, our board of directors adopted, subject to
             shareholder approval, the 2000 Stock Incentive Plan (the 2000
             Plan). The 2000 Plan is expected to become effective upon the
             signing of the underwriting agreement for the Company's initial
             public offering. At that time, all outstanding options under the
             1997 Plan will be transferred to the 2000 Plan and no further
             grants shall be made under the 1997 Plan. Transferred options shall
             continue to be governed by their existing terms, unless the
             compensation committee decides to extend one or more features of
             the 2000 Plan to those options.

             A total of 8,750,000 shares of the Company's common stock have been
             reserved for issuance under the 2000 Plan. The initial share
             reserve includes 7,450,000 shares which are expected to be
             available under the 1997 Stock Plan upon the closing of the
             Company's initial public offering. The share reserve will be
             increased annually on the first trading day in January of each
             calendar year, by an amount equal to 3% of the total number of
             shares of common stock outstanding on the last trading day of
             December in the prior calendar year. Annual increases shall not
             exceed 2,000,000 shares. When a grant expires or is terminated
             before it is exercised, the shares not acquired pursuant to the
             grants shall again become available for issuance under the 2000
             Plan.

       (c)  2000 EMPLOYEE STOCK PURCHASE PLAN

             On January 18, 2000, our board of directors adopted, subject to
             shareholder approval, the 2000 Employee Stock Purchase Plan (the
             Employee Plan). The Employee Plan is expected to become effective
             upon the signing of the underwriting agreement for the Company's
             initial public offering. A total of 250,000 shares of the Company's
             common stock have been reserved for issuance under the Employee
             Plan. The share reserve will be increased annually on the first
             trading day in January of each calendar year, by an amount equal to
             2% of the total number of shares of common stock outstanding on the
             last trading day of December in the prior calendar year. Annual
             increases shall not exceed 1,300,000 shares.

             The Employee Plan will have a series of successive offering
             periods, each with a maximum duration of 24 months. The initial
             offering period will commence upon the signing of the underwriting
             agreement for the Company's initial public offering and will end on
             the last business day in January 2002. Individual employees who are
             scheduled to work more than 20 hours per week for more than five
             calendar months per year are eligible to purchase shares during the
             offering periods. Participants may contribute up to 10% of their
             cash earnings through payroll deductions. The accumulated payroll
             deductions will be applied to the purchase of shares at the
             semi-annual entry date which occur on the first business day of
             February and August each year. The purchase price will be equal to
             the lower of 85% of the fair market value per share on the
             participant's entry date into the offering period, or 85% of the
             fair market value on the semi-annual entry date.

       (d)  FINANCING COMMITMENTS

             In February 2000, the Company received financing commitments from
             certain shareholders for $15.0 million in the event that the
             Company does not complete an initial public offering with gross
             proceeds of $25 million by May 31, 2000. The $15.0 million in
             commitments, if required, will be in the form of convertible
             promissory notes bearing interest at a fixed rate of 10% per annum.
             If not prepaid, the notes will convert into shares of the Company's
             next round of equity financing of at least $15.0 million. In
             connection with obtaining these commitments, the Company issued
             warrants to purchase 60,000 shares of common stock at a price of
             $4.00 per share and agreed to issue additional warrants for 180,000
             shares of common stock at the then fair market value per share if
             the loan commitments are exercised. These warrants expire upon the
             earlier of 5 years or 30 days after the consummation of an initial
             public offering.

       (e)  REINCORPORATION

             On January 18, 2000, the Company's board of directors approved,
             subject to shareholder approval which is expected in May 2000, the
             reincorporation of the Company in Delaware. In conjunction with the
             reincorporation, the authorized number of common shares will be
             increased to 100,000,000, and preferred stock of 5,000,000 shares
             will be authorized. The par value of the common shares will
             decrease to $0.001 per share. The effects of the reincorporation
             have been reflected in the accompanying financial statements.

                            MULTIPOINT NETWORKS, INC.
               NOTES TO THE STATEMENT OF OPERATIONS FOR THE PERIOD
                       JANUARY 1, 1998 TO AUGUST 25, 1998


(1)   THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      (a)  THE COMPANY

           Multipoint Networks, Inc. (the "Company") was incorporated in
           California in 1987 and designed, manufactured and marketed wireless
           metropolitan-area data network products based on unique patented
           digital transceiver technology. The Company's products were
           distributed through a network of independent distributors and
           value-added resellers located throughout Latin America, North
           American and Asia-Pacific.

           On August 26, 1998 the Company was acquired by Wireless, Inc.

      (b)  REVENUE RECOGNITION

           Revenues are recognized upon product shipment, provided that
           significant support obligations, if any, are satisfied and collection
           of the resulting receivables is probable. Estimated warranty costs
           are accrued at the time of sale based upon the Company's historical
           experience.

      (c)  USE OF ESTIMATES

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

      (d)  PROPERTY AND EQUIPMENT

           Depreciation and amortization of property and equipment is provided
           using the straight-line method over the estimated useful lives of the
           respective assets, which range from three to five years. Equipment
           held under capital leases is amortized using the straight-line method
           over the shorter of the lease term or the estimated useful life of
           the asset.

      (e)  CASH EQUIVALENTS

           The Company considers all highly liquid investments with an original
           maturity of three months or less to be cash equivalents. Cash and
           cash equivalents are deposited with high credit quality financial
           institutions.

      (f)  RESEARCH AND DEVELOPMENT

           Costs incurred in the research and development of new products and
           enhancements to existing products are expensed as incurred until the
           technological feasibility of the product or enhancement has been
           established. Technological feasibility is established when a product
           design and a working model have been completed and the completeness
           of the working model, and its consistency with the product design,
           have been confirmed by testing. After establishing technological
           feasibility, material development costs are capitalized. The
           capitalized cost is then amortized on a straight-line basis over the
           estimated product life, or is amortized based on the ratio of current
           revenues to total projected product revenues, whichever is greater.
           To date, the period between completion of a working model and the
           general release of the product has been short and development costs
           qualifying for capitalization have been insignificant. Accordingly,
           the Company has not capitalized any development costs.

               NOTES TO THE STATEMENT OF OPERATIONS FOR THE PERIOD
                 JANUARY 1, 1998 TO AUGUST 25, 1998--(CONTINUED)


      (g)  INVENTORIES

           Inventory is stated at the lower of cost, determined on a first-in
           first-out basis or net realizable value.

      (h)  INCOME TAXES

           The Company utilizes the asset and liability method of accounting for
           income taxes. Under this method, deferred tax assets and liabilities
           are determined based on the difference between the financial
           statement and tax basis of assets and liabilities using enacted tax
           rates in effect for the year in which the differences are expected to
           affect taxable income. Valuation allowances are established when
           necessary to reduce deferred tax assets to the amounts expected to be
           recovered.

      (i)  COMPREHENSIVE INCOME

           The Company does not have any components of comprehensive income,
           consequently comprehensive loss consists entirely of net loss for all
           periods presented.

(2)   STOCKHOLDERS' EQUITY

      (a)  SERIES 1 NONREDEEMABLE PREFERRED STOCK

           At August 25, 1998, the Company had 19,534,200 shares of Series 1
           Nonredeemable Convertible Preferred Stock issued and outstanding.
           Holders of Series 1 Preferred Stock are entitled to a noncumulative
           dividend, when and if declared by the Board of Directors, at the
           minimum rate of $0.02 per share per annum, prior and in preference to
           any distribution on the Common Stock. In the event of any
           liquidation, dissolution or winding up of the Company, the holders of
           Series 1 Preferred Stock shall be entitled to receive, prior and in
           preference to any distribution on the Common Stock, the amount of
           $0.4875 per share plus an amount equal to all declared but unpaid
           dividends on such shares.

           Each share of Series 1 Preferred Stock is convertible at the option
           of the holder at any time in Common Stock at the initial conversion
           rate of one share Common Stock for each share of Series 1 Preferred
           Stock. The initial conversion rate of the Series 1 Preferred Stock is
           subject to adjustment as provided in the Articles of Incorporation.
           Each share of Series 1 Preferred Stock shall automatically be
           converted into shares of Common Stock at the then effective
           conversion rate upon the closing of a firm commitment underwritten
           initial public offering of the Company's Common Stock at a price per
           share not less than $0.75 per share and an aggregate offering price
           to the public of not less than $10,000,000, exclusive of underwriting
           commissions and offering expenses.

           Each share of Series 1 Preferred Stock is entitled to the number of
           votes equal to the number of share of Common Stock into which the
           shares of Series 1 Preferred Stock could be converted.

      (b)  COMMON STOCK

           The Company is authorized to issue 60,000,000 shares of no par value
           common stock. At January 1, 1998 and August 25, 1998, the number of
           shares of common stock outstanding was 30,806,754.

(3)   INCOME TAXES

      The Company has incurred significant losses since inception and has not
      incurred any income tax expense to date. The income tax benefit differed
      from the amounts computed by applying the U.S. Federal income tax rate of
      34% to pretax loss as a result of the following:

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's board of directors to grant indemnification to
directors and officers in terms sufficiently broad to permit the indemnification
under certain circumstances for liabilities (including reimbursement for
expenses incurred) arising under the Securities Act of 1933, as amended (the
"Securities Act"). Article VII, Section 6 of our bylaws provides for mandatory
indemnification of our directors and officers and permissible indemnification of
employees and other agents to the maximum extent permitted by the Delaware
General Corporation Law. Our certificate of incorporation provides that, subject
to Delaware law, our directors will not be personally liable for monetary
damages for breach of the directors' fiduciary duty as directors to Wireless,
Inc. and its stockholders. This provision in the certificate of incorporation
does not eliminate the directors' fiduciary duty, and in appropriate
circumstances equitable remedies such as injunctive or other forms of
non-monetary relief will remain available under Delaware law. In addition, each
director will continue to be subject to liability for breach of the director's
duty of loyalty to the company or our stockholders for acts or omissions not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
unlawful under Delaware law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws. We have entered into indemnification
agreements with our officers and directors, a form of which is attached as
Exhibit 10.3 hereto and incorporated herein by reference. The indemnification
agreements provide our officers and directors with further indemnification to
the maximum extent permitted by the Delaware General Corporation Law. We
maintain directors and officers liabilities insurance. Reference is made to
Section 8 of the Underwriting Agreement contained in Exhibit 1.1 hereto,
indemnifying officers and directors of the Registrant against certain
liabilities and Section 1.7 of the Sixth Amended and Restated Investors Rights
Agreement contained in Exhibit 4.1 hereto, indemnifying the parties thereto,
including certain controlling stockholders, against certain liabilities.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

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

          (a) The Registrant issued and sold 5,027,547 shares of common stock to
     employees and consultants for an aggregate purchase price of $1,283,527
     pursuant to direct stock issuances and the exercise of options under its
     1997 Stock Option/Stock Issuance Plan.

                                      II-1
<PAGE>

          (b) In May 1997, the Registrant issued and sold an aggregate of

     aggregate of purchase price of $3,000,000.

          (c) In May 1997, the Registrant issued a warrant to Imperial Bank to
     purchase up to 30,460 shares of its common stock at an exercise price of

          (d) In October 1997, the Registrant issued and sold an aggregate of
     750,000 shares of Series B Preferred Stock to one investor for an aggregate

          (e) In June 1998, the Registrant entered into an agreement to acquire
     Multipoint Networks, Inc., or Multipoint, whereby the purchase price was
     payable in shares of the Registrant's common stock and Series C Preferred
     Stock. In August 1998, the Registrant completed the acquisition and paid an
     aggregate of 2,746,053 shares of its common stock to the principals of

     holders of Multipoint Series A-1 Preferred Stock. In November 1999, 59,983
     shares of Series C Preferred Stock were repurchased by the Company from a
     single investor for an aggregate purchase price of $79,777.

          (f) In October 1998, the Registrant issued a warrant to Silicon Valley
     Bank to purchase up to 48,000 shares of its Series D Preferred Stock at an
     exercise price of $1.25 per share.

          (g) In March 1999, the Registrant issued and sold an aggregate of
     6,465,221 shares of Series D Preferred Stock to several investors for an
     aggregate purchase price of $8,176,266.

          (h) In August 1999, the Registrant issued to an investor a
     subordinated debenture in a principal amount of $1,000,000 which is
     convertible into shares of its Series E Preferred Stock at an exercise
     price of $3.125 per share.

          (i) In September 1999, the Registrant issued a warrant to Silicon
     Valley Bank to purchase up to 20,000 shares of its Series E Preferred Stock
     at an exercise price of $2.50 per share. In December 1999, the Registrant's
     board of directors reduced the exercise price to $2.42 per share and
     adjusted the number of shares issuable upon exercise of the warrant to
     20,662.

          (j) In September 1999, the Registrant issued and sold an aggregate of
     3,600,000 shares of Series E Preferred Stock and warrants to purchase an
     aggregate of 362,000 shares of common stock at an exercise price of $0.75
     per share (subject to adjustment) to several investors for an aggregate
     purchase price of $9,003,600. In December 1999, the Registrant's board of
     directors reduced the exercise price of the warrants to $2.42 per share and
     adjusted the number of shares issuable upon exercise of the warrants to
     362,000.

          (k) In January 2000, the Registrant issued and sold an aggregate of
     3,000,000 shares of Series F Preferred Stock to two investors for an

     consultants to purchase up to an aggregate of 100,000 shares of its common
     stock at an exercise price of $2.50 per share.

     investors to purchase up to an aggregate of 60,000 shares of its common
     stock at an exercise price of $4.00 per share.

     None of the foregoing transactions involved any underwriters, underwriting
discounts or commissions, or any public offering, and we believe that each
transaction was exempt from the registration requirements of the Securities Act
by virtue of Section 4(2) thereof, Regulation D promulgated thereunder or Rule
701 pursuant to compensatory benefit plans and contracts relating to
compensation as provided under Rule 701. The recipients in each transaction
represented their intention to acquire the securities for investment only and
not with a view to or for sale in connection with any distribution thereof, and
appropriate legends were affixed to the share certificates and instruments
issued in these transactions. All recipients had adequate access, through their
relationships with us, to information about us.

ITEM 17. UNDERTAKINGS

     We hereby undertake to provide to the underwriters at the closing specified
in the underwriting agreement, certificates in such denominations and registered
in such names as required by the underwriters to permit prompt delivery to each
purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to our directors, officers and controlling persons pursuant to
the Delaware General Corporation Law, our certificate of incorporation or our
bylaws, indemnification agreements entered into between the company and our
officers and directors, the underwriting agreement, or otherwise, we have been
advised that in the opinion of the commission such indemnification is against
public policy as expressed in the Securities Act, and is, therefore,
unenforceable. If a claim for indemnification against such liabilities (other
than the payment by us of expenses incurred or paid by any of our directors,
officers or controlling persons in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, we will, unless in the opinion
of our counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question of whether such indemnification
by us is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.

     The undersigned registrant hereby undertakes:

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

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

                      AGREEMENT AND PLAN OF REORGANIZATION

          This AGREEMENT AND PLAN OF REORGANIZATION (the "AGREEMENT") is made
and entered into as of June 4, 1998, by and among Wireless, Inc., a California
corporation ("ACQUIROR"), the shareholders of Acquiror listed on SCHEDULE A
hereto (the "ACQUIROR SHAREHOLDERS"), Multipoint Networks, Inc., a California
corporation ("TARGET"), and the shareholders of Target listed On SCHEDULE B
hereto (the "TARGET SHAREHOLDERS").

                                    RECITALS

          A. The Boards of Directors of Target and Acquiror believe it is in the
best interests of their respective companies and the shareholders of their
respective companies that Target and Acquiror combine into a single company
through the statutory merger of Target with and into Acquiror (the "MERGER")
and, in furtherance thereof, have approved the Merger.

          B. Since July 1997, William Gibson and Charles Pai, the Chief
Executive Officer and Chief Financial Officer of Acquiror, respectively, have
also been serving as the Chief Executive Officer and Chief Financial Officer,
respectively, of Target. Certain other representatives of Acquiror have also
been acting on behalf of Target. In addition, Acquiror owns in excess of twenty
percent (20%) of the capital stock of Target.

          C. Various of the functional units of Acquiror and Target,
including sales, marketing, finance and engineering, are currently combined.

          D. Carol Lefcourt, a director of Acquiror, and Michael Hone, a
director of Target, have been authorized to sign this Agreement on behalf of
Acquiror and Target, respectively.

          E. Pursuant to the Merger, among other things, each outstanding share
of capital stock of Target ("TARGET CAPITAL STOCK"), shall be converted into
shares of capital stock of Acquiror ("ACQUIROR CAPITAL STOCK"), at the rates set
forth herein.

          F. Target and Acquiror desire to make certain representations and
warranties and other agreements in connection with the Merger.

          G. The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "CODE"), and to cause the Merger to qualify as a
reorganization under the provisions of Section 368(a)(1)(A) of the Code.

          NOW, THEREFORE, in consideration of the covenants and representations
set forth herein, and for other good and valuable consideration, the parties
agree as follows:

<PAGE>


                                    ARTICLE I

                                   THE MERGER

          1.1. THE MERGER. At the Effective Time (as defined in Section 1.2)
and subject to and upon the terms and conditions of this Agreement, the
Agreement of Merger attached hereto as EXHIBIT A (the "AGREEMENT OF MERGER") and
the applicable provisions of the California Corporations Code ("CALIFORNIA
LAW"), Target shall be merged with and into Acquiror, the separate corporate
existence of Target shall cease, and Acquiror shall continue as the surviving
corporation. Acquiror as the surviving corporation after the Merger is
hereinafter sometimes referred to as the "SURVIVING CORPORATION."

          1.2. CLOSING; EFFECTIVE TIME. The closing of the transactions
contemplated hereby (the "CLOSING") shall take place as soon as practicable
after the satisfaction or waiver of each of the conditions set forth in Article
VI hereof or at such other time as the parties hereto agree (the date on which
the Closing shall occur, the "CLOSING DATE"). The Closing shall take place at
the offices of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP,
155 Constitution Drive, Menlo Park, California, or at such other location as the
parties hereto agree. On the Closing Date, the parties hereto shall cause the
Merger to be consummated by filing the Agreement of Merger, together with the
required officers' certificates, with the Secretary of State of the State of
California, in accordance with the relevant provisions of California Law (the
time and date of such filing being the "EFFECTIVE TIME" and the "EFFECTIVE
DATE," respectively).

          1.3. EFFECT OF THE MERGER. At the Effective Time, the effect of
the Merger shall be as provided in this Agreement, the Agreement of Merger and
the applicable provisions of California Law. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time, all the property,
rights, privileges, powers and franchises of Target shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Target shall become the
debts, liabilities and duties of the Surviving Corporation.

          1.4. ARTICLES OF INCORPORATION; BYLAWS.

               (a) At the Effective Time, the Restated Articles of Incorporation

Corporation until thereafter amended as provided by California Law.

               (b) The Bylaws of Acquiror, as in effect immediately prior to the
Effective Time, shall be the Bylaws of the Surviving Corporation until

          1.5. DIRECTORS AND OFFICERS. At the Effective Time, the directors of

Effective Time shall be the officers of the Surviving Corporation, to hold
office until


                                       2
<PAGE>

such time as such officers resign, are removed or their respective successors
are duly elected or appointed and qualified.

          1.6. EFFECT ON CAPITAL STOCK. By virtue of the Merger and without any
action on the part of Acquiror, Target or the holders of any of Target's
securities:

               (a) CONVERSION OF TARGET CAPITAL STOCK. The maximum number of
shares of Acquiror Common and Preferred Stock to be issued (including Acquiror
Common Stock to be reserved for issuance upon exercise of warrants to purchase
shares of Target Common Stock (the "TARGET WARRANTS") and options to purchase
shares of Target Common Stock (the "TARGET OPTIONS") assumed by Acquiror
pursuant to Section 5.11 hereof) in exchange for the acquisition by Acquiror of
all outstanding Target Capital Stock and all unexpired and unexercised Target
Options and Target Warrants shall be 2,955,195 and 2,146,867 shares,
respectively, reduced as a result of any Dissenting Shares (as defined below).
No adjustment shall be made in the number of shares of Acquiror Common or
Preferred Stock issued in the Merger as a result of (x) any increase or decrease
in the market value of Acquiror Common or Preferred Stock prior to the Effective
Time or (y) any cash proceeds received by Target from the date hereof to the
Closing Date pursuant to the exercise of currently outstanding Target Options or
Target Warrants. Subject to the terms and conditions of this Agreement and the
Agreement of Merger as of the Effective Time, by virtue of the Merger and
without any action on the part of the holder of any shares of Target Capital
Stock:

                   (i) At the Effective Time, each share of Target Common Stock
issued and outstanding immediately prior to the Effective Time (other than
shares to be cancelled pursuant to Section 1.6(b) and shares, if any, held by
persons who have not voted such shares for approval of the Merger and with
respect to which such persons shall become entitled to exercise dissenters'
rights in accordance with Chapter 13 of the California Law ("DISSENTING
SHARES")) shall be converted and exchanged for such number of shares of Acquiror
Common Stock as shall be determined in accordance with item (i) of EXHIBIT B
hereof (the "COMMON EXCHANGE RATIO").

                   (ii) At the Effective Time, each share of Target Series 1
Preferred Stock issued and outstanding immediately prior to the Effective Time
(other than shares to be cancelled pursuant to Section 1.6(b) and Dissenting
Shares) shall be converted and exchanged for such number of shares of Acquiror
Series C Preferred Stock as shall be determined in accordance with item (ii) of
EXHIBIT B hereof (the "SERIES 1 EXCHANGE RATIO").

               (b) CANCELLATION OF TARGET CAPITAL STOCK OWNED BY ACQUIROR OR
TARGET. At the Effective Time, each share of Target Capital Stock owned by
Acquiror or any direct or indirect wholly owned subsidiary of Acquiror or of
Target immediately prior to The Effective Time shall be canceled and
extinguished without any conversion thereof.

               (c) TARGET STOCK OPTION PLANS. At the Effective Time, the Target
1992 Stock Option Plan and the Target 1996 Stock Option Plan (the "TARGET STOCK
OPTION PLANS") and all options to purchase Target Common Stock then outstanding
under the Target Stock Option Plans shall be assumed by Acquiror in accordance
with Section 5.11.

                                       3

<PAGE>

               (d) TARGET WARRANTS. At the Effective Time, all outstanding
Target Warrants that do not terminate by their terms shall be converted into
warrants to acquire Acquiror Common Stock in accordance with their terms.

               (e) ADJUSTMENTS TO EXCHANGE RATIOS. The Exchange Ratios shall be
adjusted to reflect fully the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Acquiror Capital Stock or Target Capital Stock), reorganization,
recapitalization or other like change with respect to Acquiror Capital Stock or
Target Capital Stock occurring after the date hereof and prior to the Effective
Time.

               (f) FRACTIONAL SHARES. No fraction of a share of Acquiror Common
or Preferred Stock will be issued, but in lieu thereof each holder of shares of
Target Capital Stock who would otherwise be entitled to a fraction of a share of
Acquiror Common or Preferred Stock (after aggregating all fractional shares of
Acquiror Common or Preferred Stock to be received by such holder) shall receive
from Acquiror an amount of cash (rounded to the nearest whole cent) equal to the
product of (i) such fraction, multiplied by (ii) the price of one share of
Acquiror Common or Preferred Stock, as the case may be, immediately prior to the
Merger, as determined by the Board of Directors of Acquiror (the "CLOSING
PRICE.")

               (g) DISSENTERS' RIGHTS. Any Dissenting Shares shall not be
converted into Acquiror Common or Preferred Stock, but shall instead be
converted into the right to receive such consideration as may be determined to
be due with respect to such Dissenting Shares pursuant to California Law. Target
agrees that, except with the prior written consent of Acquiror, or as required
under California Law, it will not voluntarily make any payment with respect to,
or settle or offer to settle, any such purchase demand. Each holder of
Dissenting Shares ("DISSENTING SHAREHOLDER") who, pursuant to the provisions of
California law, becomes entitled to payment of the fair value for shares of
Target Capital Stock shall receive payment therefor (but only alter the value
therefor shall have been agreed upon or finally determined pursuant to such
provisions). If, after the Effective Time, any Dissenting Shares shall lose
their status as Dissenting Shares, Acquiror shall issue and deliver, upon
surrender by such shareholder of certificate or certificates representing shares
of Target Capital Stock, the number of shares of Acquiror Common or Preferred
Stock to which such shareholder would otherwise be entitled under this Section
1.6 and the Agreement of Merger.

               (h) Acquiror and Target each contemplate that they may incur
certain indebtedness for money borrowed prior to the Effective Time. Any such
indebtedness incurred by Target prior to the Effective Time will, by virtue of
the Merger, become indebtedness of the Surviving Corporation. Each of such
parties also contemplates that any such amounts (together with interest) will be
converted into Preferred Stock in the next equity financing consummated by the
Surviving Corporation after the Closing Date. Acquiror and Target also
contemplate that such additional indebtedness will not affect the exchange
rates in the Merger.

          1.7. SURRENDER OF CERTIFICATES.

               (a) EXCHANGE AGENT. Gibson Dunn & Crutcher, counsel to the
Acquiror, shall act as exchange agent (the "EXCHANGE AGENT") in the Merger.


                                       4
<PAGE>

               (b) ACQUIROR TO PROVIDE COMMON STOCK AND CASH. Promptly after the
Effective Time, Acquiror shall make available to the Exchange Agent for exchange
in accordance with this Article I, through such reasonable procedures as
Acquiror may adopt, (i) the shares of Acquiror Common and Preferred Stock
issuable pursuant to Section 1.6(a) in exchange for shares of Target Capital
Stock outstanding immediately prior to the Effective Time, and (ii) cash in an
amount sufficient to permit payment of cash in lieu of fractional shares
pursuant to Section 1.6(f).

               (c) EXCHANGE PROCEDURES. Promptly after the Effective Time,
Acquiror shall cause to be mailed to each holder of record of a certificate or
certificates (the "CERTIFICATES") that immediately prior to the Effective Time
represented outstanding shares of Target Capital Stock, whose shares were
converted into the right to receive shares of Acquiror Common or Preferred Stock
(and cash in lieu of fractional shares) pursuant to Section 1.6, (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon receipt of the
Certificates by the Exchange Agent, and shall be in such form and have such
other provisions as Acquiror may reasonably specify) and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for certificates
representing shares of Acquiror Common or Preferred Stock (and cash in lieu of
fractional shares). Upon surrender of a Certificate for cancellation to the
Exchange Agent or to such other agent or agents as may be appointed by Acquiror,
together with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, the holder of such Certificate shall
be entitled to receive in exchange therefor a certificate representing the
number of whole shares of Acquiror Common or Preferred Stock and payment in lieu
of fractional shares that such holder has the right to receive pursuant to
Section 1.6, and the Certificate so surrendered shall forthwith be canceled.
Until so surrendered, each outstanding Certificate that, prior to the Effective
Time, represented shares of Target Capital Stock will be deemed from and after
the Effective Time, for all corporate purposes, other than the payment of
dividends, to evidence the ownership of the number of full shares of Acquiror
Common or Preferred Stock into which such shares of Target Capital Stock shall
have been so converted and the right to receive an amount in cash in lieu of the
issuance of any fractional shares in accordance with Section 1.6.

               (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No
dividends or other distributions with respect to Acquiror Common or Preferred
Stock with a record date after the Effective Time shall be paid to the holder of
any unsurrendered Certificate with respect to the shares of Acquiror Common or
Preferred Stock represented thereby until the holder of record of such
Certificate surrenders such Certificate. Subject to applicable law, following
surrender of any such Certificate, there shall be paid to the record holder of
the certificates representing whole shares of Acquiror Common or Preferred Stock
issued in exchange therefor, without interest, at the time of such surrender,
the amount of any such dividends or other distributions with a record date after
the Effective Time that would have been previously payable (but for the
provisions of this Section 1.7(d)) with respect to such shares of Acquiror
Common or Preferred Stock.

               (e) TRANSFERS OF OWNERSHIP. If any certificate for shares of
Acquiror Common or Preferred Stock is to be issued in a name other than that in
which the Certificate surrendered in exchange therefor is registered, it shall
be a condition of the issuance thereof that

                                       5
<PAGE>

the Certificate so surrendered is properly endorsed and otherwise in proper form
for transfer and that the person requesting such exchange will have paid to
Acquiror or any agent designated by it any transfer or other taxes required by
reason of the issuance of a certificate for shares of Acquiror Common or
Preferred Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Acquiror or any
agent designated by it that such tax has been paid or is not payable.

               (f) NO LIABILITY. Notwithstanding anything to the contrary in
this Section 1.7, none of the Exchange Agent, Acquiror or any party hereto shall
be liable to any person for any amount properly paid to a public official
pursuant to any applicable abandoned property, escheat or similar law.

               (g) DISSENTING SHARES. The provisions of this Section 1.7 shall
also apply to Dissenting Shares that lose their status as such, except that the
obligations of Acquiror under this Section 1.7 shall commence on the date of
loss of such status and the holder of such shares shall be entitled to receive
in exchange for such shares the number of shares of Acquiror Common or Preferred
Stock to which such holder is entitled pursuant to Section 1.6 hereof.

          1.8. NO FURTHER OWNERSHIP RIGHTS IN TARGET CAPITAL STOCK. All shares
of Acquiror Common or Preferred Stock issued upon the surrender for exchange of
shares of Target Capital Stock in accordance with the terms hereof (including
any cash paid in lieu of fractional shares) shall be deemed to have been issued
in full satisfaction of all rights pertaining to such shares of Target Capital
Stock, and there shall be no further registration of transfers on the records of
the Surviving Corporation of shares of Target Capital Stock that were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article I.

          1.9. LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of
Acquiror Common or Preferred Stock (and cash in lieu of fractional shares) as
may be required pursuant to Section 1.6; provided, however, that Acquiror may,
in its discretion and as a condition precedent to the issuance thereof, require
the owner of such lost, stolen or destroyed Certificates to deliver a bond in
such sum as it may reasonably direct as indemnity against any claim that may be
made against Acquiror, the Surviving Corporation or the Exchange Agent with
respect to the Certificates alleged to have been lost, stolen or destroyed.

          1.10. TAX CONSEQUENCES. It is intended by the parties hereto that the
Merger shall constitute a reorganization within the meaning of Section 368 of
the Code. No party shall take any action that would, to such party's knowledge,
cause the Merger to fail to qualify as a reorganization within the meaning of
Section 368 of the Code.

          1.11. EXEMPTION FROM REGISTRATION. The shares of Acquiror Common and
Preferred Stock to be issued in connection with the Merger will be issued in a
transaction exempt from registration under the Securities Act of 1933, as
amended (the "SECURITIES ACT"), by reason of Section 3(a)(10) thereof. The
shares of Acquiror Common and Preferred Stock to be issued in

                                       6
<PAGE>

connection with the Merger will be qualified under California Law, pursuant to
Section 25121 thereof, after a fairness hearing has been held pursuant to the
authority granted by Section 25142 of such law. Such fairness hearing will also
address the assumption by Acquiror of the Target Options and Target Warrants, as
described in Sections 1.6(c) and 1.6(d) hereof, respectively. Each of Acquiror
and Target shall use its best efforts to file an application for issuance of a
permit to issue such securities and assume such options and warrants as soon as
practicable after the date of this Agreement. The registration of certain of the
shares with the Securities and Exchange Commission (the "SEC") and their resale
shall be subject to the terms and conditions of a registration rights agreement
in a form reasonably acceptable to Target and Acquiror (the "REGISTRATION RIGHTS
AGREEMENT").

          1.12. TAKING OF NECESSARY ACTION: FURTHER ACTION. If, at any time
after the Effective Time, any further action is necessary or desirable to carry
out the purposes of this Agreement and to vest the Surviving Corporation with
full right, title and possession to all assets, property, rights, privileges,
powers and franchises of Target, the officers and directors of Acquiror are
fully authorized in the name of their respective corporations or otherwise to
take, and shall take, all such lawful and necessary action, so long as such
action is not inconsistent with this Agreement.

                                   ARTICLE II

                      REPRESENTATIONS AND WARRANTIES OF TARGET

          Target and the Target Shareholders represent and warrant to
Acquiror that the statements contained in this Article II are true and correct,
except as set forth in the disclosure letter delivered by Target to Acquiror
prior to the execution and delivery of this Agreement and attached hereto as
SCHEDULE C (the "TARGET DISCLOSURE LETTER"). Any reference in this Article II to
an agreement being "enforceable" shall be deemed to be qualified to the extent
such enforceability is subject to (i) laws of general application relating to
bankruptcy, insolvency, moratorium and the relief of debtors and (ii) the
availability of specific performance, injunctive relief and other equitable
remedies.

          2.1. ORGANIZATION, STANDING AND POWER. Target is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization. Target has the corporate power to own its
properties and to carry on its business as now being conducted and as proposed
to be conducted and is duly qualified to do business and is in good standing in
each jurisdiction in which the failure to be so qualified and in good standing
would have a Material Adverse Effect (as defined in Section 9.2) on Target.
Target has delivered to Acquiror a true and correct copy of the Articles of
Incorporation and Bylaws or other charter documents, as applicable, of Target,
each as amended to date. Target is not in violation of any of the provisions of
its Articles of Incorporation or Bylaws or equivalent organizational documents.
Target does not directly or indirectly own any equity or similar interest in, or
any interest convertible or exchangeable or exercisable for, any equity or
similar interest in, any corporation, partnership, joint venture or other
business association or entity.

          2.2. CAPITAL STRUCTURE. The authorized capital stock of Target
consists of 60,000,000 shares of Common Stock and 30,000,000 shares of Preferred
Stock (20,000,000 of


                                       7
<PAGE>

which have been designated as Series 1 Preferred Stock), of which there were
issued and outstanding as of the date of this Agreement 30,806,754 shares of
Common Stock and 19,534,200 shares of Series 1 Preferred Stock (the "SERIES 1
PREFERRED"). There are no other outstanding shares of capital stock or voting
securities and no outstanding commitments to issue any shares of capital stock
or voting securities after the date of this Agreement, other than pursuant to
the exercise of (i) outstanding Target Warrants and (ii) options outstanding as
of the date of this Agreement under the Target Stock Option Plans. All
outstanding shares of Target Capital Stock are duly authorized, validly issued,
fully paid and non-assessable and are free of any liens or encumbrances, other
than any liens or encumbrances created by or imposed upon the holders thereof,
and are not subject to preemptive rights, rights of first refusal, rights of
first offer or similar rights created by statute, the Articles of Incorporation
or Bylaws of Target, or any agreement to which Target is a party or by which it
is bound. As of the date of this Agreement, Target has reserved 20,000,000
shares of Common Stock for issuance upon conversion of the Series 1 Preferred.
As of the date of this Agreement, there are currently outstanding (i) options to
purchase 2,222,100 shares of Common Stock granted to employees and other service
providers pursuant to the Target Stock Option Plans, and (ii) warrants to
purchase 988,554 shares of Common Stock upon exercise of the Target Warrants.
Except for (i) the rights created pursuant to this Agreement and (ii) Target's
right to repurchase any unvested shares under the Target Stock Option Plans,
there are no other options, warrants, calls, rights, commitments or agreements
of any character to which Target is a party or by which it is bound obligating
or allowing Target to issue, deliver, sell, repurchase or redeem, or cause to be
issued, delivered, sold, repurchased or redeemed, any shares of Target Capital
Stock or obligating Target to grant, extend, accelerate the vesting of, change
the price of, or otherwise amend or enter into any such option, warrant, call,
right, commitment or agreement. There are no contracts, commitments or
agreements relating to the voting, purchase or sale of Target Capital Stock (i)
between or among Target and any of its shareholders and (ii) to the best of
Target's knowledge, among any of Target's shareholders or between any of
Target's shareholders and any third party. The terms of the Target Stock Option
Plans permit the assumption of such Target Stock Option Plans by Acquiror or the
substitution of options to purchase Acquiror Common Stock as provided in this
Agreement, without the consent or approval of the holders of the outstanding
options, the Target shareholders, or otherwise and without any acceleration of
the exercise schedule or vesting provisions in effect for such options. True and
complete copies of all agreements and instruments relating to or issued under
the Target Stock Option Plans have been made available to Acquiror, and such
agreements and instruments have not been amended, modified or supplemented, and
there are no agreements to amend, modify or supplement such agreements or
instruments from the form made available to Acquiror. All outstanding Common
Stock and Series 1 Preferred was issued in compliance with all applicable
federal and state securities laws.

Target contemplates that it may incur certain indebtedness (which may be
convertible into securities of such corporation and which may include warrant
coverage) for money borrowed prior to the Effective Time. Any such indebtedness
incurred by Target prior to the Effective Time will, by virtue of the Merger,
become indebtedness of the Surviving Corporation. Each of Acquiror and Target
contemplates that any such amounts (together with interest) will be convened
into Preferred Stock in the next equity financing consummated by the Surviving
Corporation after the Closing Date. Acquiror and Target also contemplate that
such additional indebtedness will not affect the exchange rates in the Merger.

          2.3. AUTHORITY.

               (a) Target has all requisite corporate power and authority to

Agreement and the Agreement of Merger and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of Target, subject only to the approval of the
Merger by Target's shareholders. This Agreement and Agreement of Merger have
been duly executed and delivered by Target and constitute the valid and binding
obligations of Target enforceable against Target in accordance with their terms.

               (b) The execution and delivery of this Agreement and the
Agreement of Merger by Target do not, and the consummation of the transactions
contemplated hereby and thereby will not, conflict with, or result in any
violation of, or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation or acceleration of
any obligation or loss of any benefit under (i) any provision of the Articles of
Incorporation or Bylaws of Target, as amended, or (ii) any Material Agreement
(as defined in Section 2.19), permit, concession, franchise, license, judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to Target
or any of its properties or assets.

               (c) No consent, approval, order or authorization of, or
registration, declaration or filing with, any court, administrative agency or
commission or other governmental authority or instrumentality ("GOVERNMENTAL
ENTITY") is required by or with respect to Target in connection with the
execution and delivery of this Agreement and the Agreement of Merger or the
consummation of the transactions contemplated hereby or thereby, except for (i)
the filing of the Agreement of Merger, together with the required officers'
certificates, as provided in Section 1.2; (ii) such consents, approvals, orders,

authorizations, filings, approvals and registrations that, if not obtained or
made, would not have a Material Adverse Effect on Target and would not prevent
or materially alter or delay any of the transactions contemplated by this
Agreement.

          2.4. FINANCIAL STATEMENTS. Target has delivered to Acquiror its
unaudited financial statements (balance sheet, statement of operations,
statement of shareholders' equity and statement of cash flows) as at and for the
fiscal year ended December 31, 1997, and its unaudited financial statements
(balance sheet and statement of operations) as at and for the four-month period
ended April 30, 1998 (collectively, the "TARGET FINANCIAL STATEMENTS"). The
Target Financial Statements have been prepared in accordance with generally
accepted accounting principles ("GAAP") (except that the unaudited financial
statements do not have notes thereto) applied on a consistent basis throughout
the periods indicated and with each other. The Target Financial Statements
fairly present the financial condition and operating results of Target as of the
dates, and for the periods, indicated therein, subject in the case of the
unaudited financial statements to normal year-end audit adjustments, which are
not material in the aggregate. Target maintains a standard system of accounting
established and administered in accordance with generally accepted accounting
principles.

          2.5. ABSENCE OF CERTAIN CHANGES. Since April 30, 1998 (the "TARGET
BALANCE SHEET DATE"), Target has conducted its business in the ordinary course

or condition (whether or not covered by insurance) that has resulted in, or
might reasonably be expected to result in, a Material Adverse Effect on Target;

any change in accounting methods or practices (including any change in

a dividend or other distribution with respect to the shares of Target, or any
direct or indirect redemption, purchase or other acquisition by Target of any of
its shares of capital stock; (v) any Material Contract entered into by Target,
other than as provided to Acquiror, or any material amendment or termination of,
or default under, any Material Contract to which Target is a party or by which
it is bound; (vi) any amendment or change to the Articles of Incorporation or
Bylaws of Target; (vii) any increase in or modification of the compensation or
benefits payable or to become payable by Target to any of its directors,
employees or consultants; or (viii) any negotiation or agreement by Target to do
any of the things described in the preceding clauses (i) through (vii) (other
than negotiations with Acquiror and its representatives regarding the
transactions contemplated by this Agreement).

          2.6. ABSENCE OF UNDISCLOSED LIABILITIES. Target has no material
obligations or liabilities of any nature (matured or unmatured, fixed or
contingent) other than (i) those set forth or adequately provided for in the
Balance Sheet at April 30, 1998 (the "TARGET BALANCE SHEET"), (ii) those
incurred in the ordinary course of business prior to the Target Balance Sheet
Date and not required to be set forth in the Target Balance Sheet under GAAP,
(iii) those incurred in the ordinary course of business since the Target Balance
Sheet Date in amounts consistent with prior periods, and (iv) those incurred in
connection with the execution of this Agreement.

          2.7. LITIGATION. There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of Target, threatened
(including allegations that could form the basis for future action) against
Target or any of its properties or officers or directors (in their capacities as
such). There is no judgment, decree or order against Target, or, to the
knowledge of Target, any of its directors or officers (in their capacities as
such), that could prevent, enjoin, or materially alter or delay any of the
transactions contemplated by this Agreement, or that could reasonably be
expected to have a Material Adverse Effect on Target. All litigation to which
Target is a party (or, to the knowledge of Target, threatened to become a party)
is disclosed in the Target Disclosure Letter. Target does not have any plans to
initiate any litigation, arbitration or other proceeding against any third
party.

          2.8. GOVERNMENTAL AUTHORIZATION. Target has obtained each federal,
state, county, local or foreign governmental consent, license, permit, grant, or
other authorization of a Governmental Entity (i) pursuant to which Target
currently operates or holds any interest in any of its properties or (ii) that
is required for the operation of Target's business or the holding of any such
interest ((i) and (ii) herein collectively called "TARGET AUTHORIZATIONS"), and
all of such Target Authorizations are in full force and effect, except where the
failure to obtain or have any such Target Authorizations could not reasonably be
expected to have a Material Adverse Effect on Target.

<PAGE>

          2.9. TITLE TO PROPERTY. Target has good and marketable title to all of
its properties, interests in properties and assets, real and personal, necessary

each case free and clear of all mortgages, liens, pledges, charges or
encumbrances of any kind or character, except (i) the lien of current taxes not

rights (defined below), the foregoing representations and warranties of this
paragraph are made only to Target's knowledge.

               (b) All Target Intellectual Property that is the subject of any
application, registration or issuance with or from any governmental entity is
identified on the Target Disclosure Schedule; all such registered or issued
Intellectual Property is free from any challenge (or threat thereof) and Target
is not aware of any specific basis therefor. All such applications,
registrations and issuances have been properly maintained. Target has adequately
protected all other Target Intellectual Property through the use of
confidentiality agreements and otherwise and Target is not aware of any use,
exercise or exploitation of any Target Intellectual Property, except as
authorized by Target.

               (c) Each current and former employee and contractor of Target has
executed and delivered (and to Target's knowledge, is in compliance with) an
agreement in substantially the form of Target's standard Proprietary Information
and Inventions Agreement (in the case of an employee) or Target's standard
Consulting Agreement (in the case of a contractor) (which agreement provides

<PAGE>

         2.11. ENVIRONMENTAL MATTERS. Target is and has at all times operated
its business in material compliance with all Environmental Laws, and to the best
of Target's knowledge, no material expenditures are or will be required in order
to comply with such Environmental Laws. "ENVIRONMENTAL LAWS" means all
applicable statutes, roles, regulations, ordinances, orders, decrees, judgments,
permits, licenses, consents, approvals, authorizations, and governmental
requirements or directives or other obligations lawfully imposed by governmental
authority under federal, state or local law pertaining to the protection of the
environment, protection of public health, protection of worker health and
safety, the treatment, emission and/or discharge of gaseous, particulate and/or
effluent pollutants, and/or the handling of hazardous materials.

         2.12. TAXES.

               (a) All Tax returns, statements, reports, declarations and other
forms and documents (including without limitation estimated Tax returns and
reports and material information returns and reports) required to be filed with
any Tax authority with respect to any Taxable period ending on or before the
Closing, by or on behalf of Target (collectively, "TAX RETURNS" and individually
a "TAX RETURN"), have been or will be completed and filed when due (including
any extensions of such due date) and all amounts shown due on such Tax Returns
on or before the Effective Time have been or will be paid on or before such
date. The Target Financial Statements (i) fully accrue all actual and contingent
liabilities for Taxes with respect to all periods through the Target Balance
Sheet Date and Target has not and will not incur any Tax liability in excess of
the amount reflected on the Target Balance Sheet included in the Target
Financial Statements with respect to such periods, and (ii) properly accrue in
accordance with GAAP all material liabilities for Taxes payable after the Target
Balance Sheet Date with respect to all transactions and events occurring on or
prior to such date. All information set forth in the notes to the Target
Financial Statements relating to Tax matters is true, complete and accurate in
all material respects. No material Tax liability since the Target Balance Sheet
Date has been incurred by Target other than in the ordinary course of business,
and adequate provision has been made by Target for all Taxes since that date in
accordance with GAAP on at least a quarterly basis.

               (b) Target has previously provided or made available to Acquiror
true and correct copies of all income, franchise, and sales Tax Returns, and, as
reasonably requested by Acquiror, prior to or following the date hereof,

required to be withheld. To the best knowledge of Target, no Tax Returns filed
with respect to Taxable years of Target through the Taxable year ended December
31, 1997 in the case of the United States, have been examined and closed. Target
(or any member of any affiliated or combined group of which Target has been a
member) has not granted any extension or waiver of the limitation period
applicable to any Tax Returns that is still in effect. There is no material
claim, audit, action, suit, proceeding, or (to the knowledge of Target)
investigation now pending or (to the knowledge of Target) threatened against or
with respect to Target in respect of any Tax or assessment. No notice of
deficiency or similar document of any Tax authority has been received by Target,
and there are no liabilities for Taxes (including liabilities for interest,
additions to Tax and penalties thereon and related expenses) with respect to the
issues that have been raised (and are currently pending) by any Tax authority
that could, if determined adversely to Target, materially and adversely affect
the liability of Target for Taxes. There are no liens for


                                       12
<PAGE>

Taxes (other than for current Taxes not yet due and payable) upon the assets of
Target. Target has never been a member of an affiliated group of corporations,
within the meaning of Section 1504 of the Code. Target is in full compliance
with all the terms and conditions of any Tax exemptions or other Tax-sharing
agreement or order of a foreign government and the consummation of the Merger
will not have any adverse effect on the continued validity and effectiveness of
any such Tax exemption or other Tax-sharing agreement or order. Neither Target
nor any person on behalf of Target has entered into or will enter into any
agreement or consent pursuant to the collapsible corporation provisions of
Section 341(f) of the Code (or any corresponding provision of state, local or
foreign income tax law) or agreed to have Section 341 (f)(2) of the Code (or any
corresponding provision of state, local or foreign income tax law) apply to any
disposition of any asset owned by Target. None of the assets of Target is
property that Target is required to treat as being owned by any other person
pursuant to the so-called "safe harbor lease" provisions of former Section
168(f)(8) of the Code. None of the assets of Target directly or indirectly
secures any debt the interest on which is tax-exempt under Section 103(a) of the
Code. None of the assets of Target is "tax-exempt use property" within the
meaning of Section 168(h) of the Code. Target has not made and will not make a
deemed dividend election under Treas. Reg. Section 1.1502-32(f)(2) or a consent
dividend election under Section 565 of the Code. Target has never been a party
to any transaction intended to qualify under Section 355 of the Internal Revenue
Code or any corresponding provision of state law. Target has not participated in
(and will not participate in) an international boycott within the meaning of
Section 999 of the Code. No Target shareholder is other than a United States
person within the meaning of the Code. Target does not have and has not had a
permanent establishment in any foreign country, as defined in any applicable tax
treaty or convention between the United States of America and such foreign
country and Target has not engaged in a trade or business within any foreign
country. Target has never elected to be treated as an S-corporation under
Section 1362 of the Code or any corresponding provision of federal or state law.
All material elections with respect to Target's Taxes are reflected on the
Target Tax Returns for such periods, copies of which have been provided or made
available to Acquiror. After the date of this Agreement, no material election
with respect to Taxes will be made without the prior written consent of
Acquiror, which consent will not be unreasonably withheld or delayed. Target is
not a party to any joint venture, partnership, or other arrangement or contract
which could be treated as a partnership for federal income tax purposes. Target
is not currently and never has been subject to the reporting requirements of
Section 6038A of the Code. There is no agreement, contract or arrangement to
which Target is a party that could, individually or collectively, result in the
payment of any amount that would not be deductible by reason of Sections 280G
(as determined without regard to Section 280G(b)(4), 162 (other than 162(a)) or
404 of the Code. Target is not a party to or bound by any Tax indemnity, Tax
sharing or Tax allocation agreement (whether written or unwritten or arising
under operation of federal law as a result of being a member of a group filing
consolidated Tax returns, under operation of certain state laws as a result of
being a member of a unitary group, or under comparable laws of other states or
foreign jurisdictions) which includes a party other than Target nor does Target
owe any amount under any such Agreement. Target has previously provided or made
available to Acquiror true and correct copies of all income, franchise, and
sales Tax Returns, and, as reasonably requested by Acquiror, prior to or
following the date hereof, presently existing information statements and
reports. Target is not, and has not been, a United States real property holding
corporation (as defined in Section 897(c)(2) of the Code) during the applicable
period

                                       13
<PAGE>

specified in Section 897(c)(1)(A)(ii) of the Code. Other than by reason of the
Merger, Target has not been and will not be required to include any material
adjustment in Taxable income for any Tax period (or portion thereof) pursuant to
Section 481 or 263A of the Code or any comparable provision under state or
foreign Tax laws as a result of transactions, events or accounting methods
employed prior to the Merger.

          (c) For purposes of this Agreement, the following terms have the
following meanings: "TAX" (and, with correlative meaning, "TAXES" and "TAXABLE")

               (g) Each Plan that is intended to qualify under section 401(a) of
the Code meets the requirements for qualification under section 401(a) of the
Code and the regulations thereunder, except to the extent that such requirements

pursuant to a retroactive amendment under section 401(b) of the Code) and the
applicable provisions of ERISA and the Code and the regulations thereunder,
except to the extent that a failure to be so administered would not have a

withdrawal liability under Title IV of ERISA, except to the extent that any such
liability would not have a Material Adverse Effect.

               (i) All contributions, premiums or other payments due from the

<PAGE>

               (f) Target has complied in all material respects with the
verification requirements and the record-keeping requirements of the Immigration
Reform and Control Act of 1986 ("IRCA"); to the best knowledge of Target, the
information and documents on which Target relied to comply with IRCA are true
and correct; and there have not been any discrimination complaints filed against
Target pursuant to IRCA, and to the knowledge of Target, there is no basis for
the filing of such a complaint.

               (g) Target has not received or been notified of any complaint by
any employee, applicant, union or other party of any discrimination or other
conduct forbidden by law or contract, nor to the knowledge of Target, is there a
basis for any complaint, except such complaints as could not reasonably be
expected to have a Material Adverse Effect.

               (h) Target's action in complying with the terms of this Agreement
will not violate any agreements with any of Target's employees.

               (i) Target has filed all required reports and information with
respect to its employees that are due prior to the Closing Date and otherwise
has complied in its hiring, employment, promotion, termination and other labor
practices with all applicable federal and state laws and regulations, including
without limitation those within the jurisdiction of the United States Equal
Employment Opportunity Commission, United States Department of Labor and state
and local human rights or civil rights agencies, except to the extent that any
such failure to file or comply would not have a Material Adverse Effect on
Target. Target has filed and shall file any such reports and information that
are required to be filed prior to the Closing Date.

               (j) Target is not aware that any of its employees or contractors
is obligated under any agreement, commitments, judgment, decree, order or
otherwise (an "EMPLOYEE OBLIGATION") that would interfere with the use of his or
her best efforts to promote the interests of Target or that would conflict with
any of Target's business as conducted or proposed to be conducted. Neither the
execution nor delivery of this Agreement nor the conduct of Target's business as
conducted or proposed, will, to Target's knowledge, conflict with or result in a
breach of the terms, conditions or provisions of, or constitute a default under,
any Employee Obligation.

          2.15. RELATED-PARTY TRANSACTIONS. No employee, officer or director
of Target or member of his or her immediate family is indebted to Target, nor is
Target indebted (or committed to make loans or extend or guarantee credit) to
any of them. To the best of Target's knowledge, none of such persons has any
direct or indirect ownership interest in any firm or corporation with which
Target is affiliated or with which Target has a business relationship, or any
firm or corporation that competes with Target, except to the extent that
employees, officers, or directors of Target and members of their immediate
families own stock in publicly traded companies that may compete with the
Company. No member of the immediate family of any officer or director of Target
is directly or indirectly interested in any material contract with Target.

          2.16. INSURANCE. Target has policies of insurance and bonds of the
type and in amounts customarily carried by persons conducting businesses or
owning assets similar to those of Target. There is no material claim pending
under any of such policies or bonds as to which


                                       17
<PAGE>

coverage has been questioned, denied or disputed by the underwriters of such
policies or bonds. All premiums due and payable under all such policies and
bonds have been paid and Target is otherwise in compliance with the terms of
such policies and bonds. Target has no knowledge of any threatened termination
of, or material premium increase with respect to, any of such policies.

         2.17. COMPLIANCE WITH LAWS. Target has complied with, is not in
violation of, and has not received any notices of violation with respect to, any
federal, state, local or foreign statute, law or regulation with respect to the
conduct of its business, or the ownership or operation of its business, except
for such violations or failures to comply as could not be reasonably expected to
have a Material Adverse Effect on Target.

         2.18. BROKERS' AND FINDERS' FEES. Target has not incurred, nor will
it incur, directly or indirectly, any liability for brokerage or finders' fees
or agents' commissions or investment bankers' fees or any similar charges in
connection with this Agreement or any transaction contemplated hereby.

         2.19. MATERIAL CONTRACTS. Except for the material contracts
described in the Target Disclosure Schedule (collectively, the "TARGET MATERIAL

including without limitation:

               (a) any distributor, sales, advertising, agency or manufacturer's
representative contract;

               (b) any continuing contract for the purchase of materials,

agreement or other contract for the borrowing of money, any currency exchange,
commodities or other hedging arrangement or any leasing transaction of the type
required to be capitalized in accordance with GAAP;

               (e) any contract for capital expenditures in excess of $100,000

               (k) any license, sublicense or other agreement to which Target is
a party (or by which it or any Target Intellectual Property is bound or subject)
and pursuant to which any person has been or may be assigned, authorized to Use,
or given access to any Target Intellectual Property, other than (A) access to or
Use of standard object code product pursuant to a customary non-exclusive
end-user, object code, internal-use software license and support/maintenance
agreements entered into in the ordinary course of business or (B) access
provided in the ordinary course of business under a customary
nondisclosure/nonuse agreement;

               (l) any license, sublicense or other agreement pursuant to which
Target has been or may be assigned or authorized to Use, or has or may incurred
any obligation in connection with, (A) any third party Intellectual Property or
(B) any Target Intellectual Property;

         2.20. NO BREACH OF MATERIAL CONTRACTS. Target has performed all of
the obligations required to be performed by it and is entitled to all benefits
under, and is not alleged to be in default in respect of, any Material Contract.
Each of the Target Material Contracts is in full force and effect, and there
exists no default or event of default or event, occurrence, condition or act,
with respect to Target or to Target's knowledge with respect to the other
contracting party, or otherwise that, with or without the giving of notice, the
lapse of the time or the happening of any other event or conditions, would (A)
become a default or event of default under any Material Contract, which default
or event of default would have a Material Adverse Effect on Target or (B) result
in the loss or expiration of any material right or option by Target (or the gain
thereof by any third party) under any Material Contract. True, correct and
complete copies of all Target Material Contracts have been made available to the
Acquiror.

         2.21. THIRD-PARTY CONSENTS. The Target Disclosure Schedule lists
all contracts that require a novation or consent to assignment, as the case may
be, prior to the Effective Time so that Acquiror shall be made a party in place
of Target or as assignee (the "CONTRACTS REQUITING NOVATION OR CONSENT TO
ASSIGNMENT"). Such list is complete and accurate.

         2.22. REPRESENTATIONS COMPLETE. None of the representations or
warranties made by Target or the Target Shareholders herein or in any Schedule
hereto, including the Target Disclosure Schedule, or certificate furnished by
Target pursuant to this Agreement, when all such documents are read together in

                      REPRESENTATIONS AND WARRANTIES OF ACQUIROR

          Acquiror and the Acquiror Shareholders represent and warrant to Target
and the Former Target Shareholders (as defined in Section 8.1) that the
statements contained in this Article III are true and correct, except as set
forth in the disclosure schedule delivered by acquiror to Target to prior to the
execution and delivery of this Agreement and attached hereto as SCHEDULE D (the
"ACQUIROR DISCLOSURE SCHEDULE"). Any reference in this Article III to an
agreement being "enforceable" shall be deemed to be qualified to the extent such
enforceability is subject to (i) laws of general application relating to
bankruptcy, insolvency, moratorium and the relief of debtors and (ii) the
availability of specific performance, injunctive relief and other equitable
remedies.

          3.1. ORGANIZATION, STANDING AND POWER. Acquiror is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization. Acquiror has the corporate power to own its
properties and to carry on its business as now being conducted and as proposed
to be conducted and is duly qualified to do business and is in good standing in
each jurisdiction in which the failure to be so qualified and in good standing
would have a Material Adverse Effect on Acquiror. Acquiror has delivered to
Target a true and correct copy of the Articles of Incorporation and Bylaws or
other charter documents, as applicable, of Acquiror, each as amended to date.
Acquiror is not in violation of any of the provisions of its Articles of
Incorporation or Bylaws or equivalent organizational documents. Acquiror does
not directly or indirectly own any equity or similar interest in, or any
interest convertible or exchangeable or exercisable for, any equity or similar
interest in, any corporation, partnership, joint venture or other business
association or entity.

          3.2. CAPITAL STRUCTURE. The authorized capital stock of Acquiror
consists of 20,000,000 shares of Common Stock and 10,000,000 shares of Preferred
Stock (6,000,000 of which have been designated as Series A Preferred Stock and
750,000 of which have been designated as Series B Preferred Stock), of which
there were issued and outstanding as of the date of this Agreement 858,000
shares of Common Stock, 6,000,000 shares of Series A Preferred Stock (the
"SERIES A PREFERRED") and 750,000 shares of Series B Preferred (the "SERIES B
PREFERRED"). There are no other outstanding shares of capital stock or voting
securities and no outstanding commitments to issue any shares of capital stock
or voting securities alter the date of this Agreement, other than pursuant to
the exercise of options outstanding as of the date of this Agreement under the
Acquiror's 1997 Stock Option Plan (the "ACQUIROR STOCK OPTION PLAN"). All
outstanding shares of Acquiror Capital Stock are duly authorized, validly
issued, fully paid and non-assessable and are free of any liens or encumbrances,
other than any liens or encumbrances created by or imposed upon the holders
thereof, and are not subject to preemptive rights, rights of first refusal,
rights of first offer or similar rights created by statute, the Articles of
Incorporation or Bylaws of Acquiror, or any agreement to which Acquiror is a
party or by which it is bound. As of the date of this Agreement, Acquiror has
reserved 6,750,000 shares of Common Stock for issuance upon conversion of the
Series A Preferred and Series B Preferred. As of the date of this Agreement,
there are currently outstanding options to purchase 1,564,000 shares of Common
Stock granted to employees and other service providers pursuant to the Acquiror
Stock Option Plan. Except for (i) the rights created pursuant to this Agreement
and

<PAGE>

(ii) Acquiror's right to repurchase any unvested shares under the Acquiror Stock
Option Plan, there are no other options, warrants, calls, rights, commitments or
agreements of any character to which Acquiror is a party or by which it is bound
obligating or allowing Acquiror to issue, deliver, sell, repurchase or redeem,
or cause to be issued, delivered, sold, repurchased or redeemed, any shares of
Acquiror Capital Stock or obligating Acquiror to grant, extend, accelerate the
vesting of, change the price of, or otherwise amend or enter into any such
option, warrant, call, right, commitment or agreement. There are no contracts,
commitments or agreements relating to the voting, purchase or sale of Acquiror
Capital Stock (i) between or among Acquiror and any of its shareholders and (ii)
to the best of Acquiror's knowledge, among any of Acquiror's shareholders or
between any of Acquiror's shareholders and any third party. True and complete
copies of all agreements and instruments relating to or issued under the
Acquiror Stock Option Plan have been made available to Target, and such
agreements and instruments have not been amended, modified or supplemented, and
there are no agreements to amend, modify or supplement such agreements or
instruments from the form made available to Target. All outstanding Common
Stock, Series A Preferred and Series B Preferred was issued in compliance with
all applicable federal and state securities laws.

Acquiror contemplates that it may incur certain indebtedness (which may be
convertible into securities of such corporation and which may include warrant
coverage) for money borrowed prior to the Effective Time. Each of Acquiror and
Target contemplates that any such amounts (together with interest) will be
converted into Preferred Stock in the next equity financing consummated by the
Surviving Corporation after the Closing Date, Acquiror and Target also
contemplate that such additional indebtedness will not affect the exchanges
rates in the Merger.

of Incorporation or Bylaws of Acquiror, as amended, or (ii) any Material
Agreement (as defined in Section 3.19), permit, concession, franchise, license,

as such). There is no judgment, decree or order against Acquiror, or, to the
knowledge of Acquiror, any of its directors or officers (in their capacities as

transactions contemplated by this Agreement, or that could reasonably be
expected to have a Material Adverse Effect on Acquiror. All litigation to which

Tax Returns on or before the Effective Time have been or will be paid on or
before such date. The Acquiror Financial Statements (i) fully accrue all actual
and contingent liabilities for Taxes with respect to all periods through the
Acquiror Balance Sheet Date and Acquiror has not and will not incur any Tax
liability in excess of the amount reflected on the Acquiror Balance Sheet
included in the Acquiror Financial Statements with respect to such periods, and

payable after the Acquiror Balance Sheet Date with respect to all transactions
and events occurring on or prior to such date. All information set forth in the
notes to the Acquiror Financial Statements relating to Tax matters is true,
complete and accurate in all material respects. No material Tax liability since
the Acquiror Balance Sheet Date has been incurred by Acquiror or will be
incurred prior to the Effective Time by Acquiror other than in the ordinary

Taxes since that date in accordance with GAAP on at least a quarterly basis.

action, suit, proceeding, or (to the knowledge of Acquiror) investigation now
pending or (to the knowledge of Acquiror) threatened against or with respect to
Acquiror in respect of any Tax or assessment. No notice of deficiency or similar
document of any Tax authority has been received by Acquiror, and there are no
liabilities for Taxes (including liabilities for interest, additions to Tax and
penalties thereon and related expenses) with respect to the issues that have
been raised (and are currently pending) by any Tax authority that could, if
determined adversely to Acquiror, materially and adversely affect the liability
of Acquiror for Taxes. There are no liens for Taxes (other than for current
Taxes not yet due and payable) upon the assets of Acquiror. Acquiror has never
been a member of an affiliated group of corporations, within the meaning of
Section 1504 of the Code. Acquiror is in full compliance with all the terms and
conditions of any Tax exemptions or other Tax-sharing agreement or order of a
foreign government and the consummation of the Merger will not have any adverse
effect on the continued validity and effectiveness of any such Tax exemption or
other Tax-sharing agreement or order. Neither Acquiror nor any person on behalf
of Acquiror has entered into or will prior to the Effective Time enter into any
agreement or consent pursuant to the collapsible corporation provisions of
Section 341(f) of the Code (or any corresponding provision of state, local or
foreign income tax law) or agreed to have Section 341(f)(2) of the Code (or any
corresponding provision of state, local or foreign income tax law) apply to any
disposition of any asset owned by Acquiror. None of the assets of Acquiror is

pursuant to the so-called "safe harbor lease" provisions of former Section
168(f)(8) of the Code. None of the assets of Acquiror directly or indirectly
secures any debt the interest on which is tax-exempt under Section 103(a) of the
Code. None of the assets of Acquiror is "tax-exempt use property" within the

Code. Acquiror has never been a party to any transaction intended to qualify
under Section 355 of the Internal Revenue Code or any corresponding provision of
state law. Acquiror has not participated in (and will not participate in) an
international boycott within the meaning of Section 999 of the Code. No Acquiror

Acquiror does not have and has not had a permanent establishment in any foreign
country, as defined in any applicable tax treaty or convention between the
United States of America and such foreign country and Acquiror has not engaged
in a trade or business within any foreign country. Acquiror has never elected to
be treated as an S-corporation under Section 1362 of the Code or any
corresponding provision of federal or state law. All material elections with
respect to Acquiror's Taxes are reflected on the Acquiror Tax Returns for such
periods, copies of which have been provided or made available to Acquiror.
Acquiror is not party to any joint venture, partnership, or other arrangement or
contract which could be treated as a partnership for federal income tax
purposes. Acquiror is not currently and never has been subject to the reporting
requirements of Section 6038A of the Code. There is no agreement, contract or
arrangement to which Acquiror is a party that could, individually or
collectively, result in the payment of any amount that would not be deductible
by reason of Sections 280G (as determined without regard to Section 280G(b)(4),
162 (other than 162(a)) or 404 of the Code. Acquiror is not a party to or bound
by any Tax indemnity, Tax sharing or Tax allocation agreement (whether written
or unwritten or arising under operation of federal law as a result of being a
member of a group filing consolidated Tax returns, under operation of certain
state laws as a result of being a member of a unitary group, or under comparable
laws of other states or foreign jurisdictions) which includes a party other than
Acquiror nor does Acquiror owe any amount under any such Agreement. Acquiror has
previously provided or made available to Acquiror true and correct copies of all
income, franchise, and sales Tax Returns, and, as reasonably requested by
Acquiror, prior to or following the date hereof, presently existing information
statements and reports. Acquiror is not, and has not been, a United States real
property holding corporation (as defined in Section 897(c)(2) of the Code)
during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.
Other than by reason of the Merger, Acquiror has not been and will not be
required to include any material adjustment in Taxable income for any Tax period
(or portion thereof) pursuant to Section 481 or 263A of the Code or any
comparable provision under state or foreign Tax laws as a result of
transactions, events or accounting methods employed prior to the Merger.

               (c) As used in this Section 3.12, the term "ACQUIROR" means
Acquiror and any entity included in, or required under GAAP to be included in,
any of the Acquiror Financial Statements.

violation of, and has not received any notices of violation with respect to, any
federal, state, local or foreign statute, law or regulation with respect to the

have a Material Adverse Effect on Acquiror.

          3.18. BROKERS' AND FINDERS' FEES. Acquiror has not incurred, nor

Contract. Each of the Acquiror Material Contracts is in full force and effect,
and there exists no default or event of default or event, occurrence, condition
or act, with respect to Acquiror or to Acquiror's knowledge with respect to the
other contracting party, or otherwise that, with or without the giving of
notice, the lapse of the time or the happening of any other event or conditions,
would (A) become a default or event of default under any Material Contract,
which default or event of default would have a Material Adverse Effect on
Acquiror or (B) result in the loss or expiration of any material right or option
by Acquiror (or the gain thereof by any third party) under any Material
Contract. True, correct and complete copies of all Acquiror Material Contracts
have been made available to the Acquiror.

          3.21. REPRESENTATIONS COMPLETE. None of the representations or

Effective Time any untrue statement of a material fact, or omits or will omit at

                                   ARTICLE IV

                       CONDUCT PRIOR TO THE EFFECTIVE TIME

          4.1. CONDUCT OF BUSINESS OF TARGET AND ACQUIROR. During the period
from the date of this Agreement and continuing until the earlier of the
termination of this Agreement or the Effective Time, Target and Acquiror each
agree (except to the extent expressly contemplated by this Agreement or as
consented to in writing by the other), to carry on its business in the usual,
regular and ordinary course in substantially the same manner as heretofore
conducted. Without limiting the foregoing, except as expressly contemplated by
this Agreement, neither Target nor Acquiror shall do, cause or permit any of the
following, without the prior written consent of the other:

               (a) CHARTER DOCUMENTS. Cause or permit any amendments to its
Articles of Incorporation or Bylaws;

               (b) DIVIDENDS; CHANGES IN CAPITAL STOCK. Declare or pay any
dividends on or make any other distributions (whether in cash, stock or
property) in respect of any of its capital stock, or split, combine or
reclassify any of its capital stock or issue or authorize the issuance of any
other securities in respect of, in lieu of, or in substitution for shares of its
capital stock, or repurchase or otherwise acquire, directly or indirectly, any
shares of its capital stock except from former employees, directors and
consultants in accordance with agreements providing for the repurchase of shares
in connection with any termination of service to it;

               (c) MATERIAL CONTRACTS. Enter into any material contract,
agreement, license or commitment, or violate, amend or otherwise modify or waive
any of the terms of any of its material contracts, agreements or licenses other
than in the ordinary course of business consistent with past practice;

               (d) STOCK OPTION PLANS, ETC. Accelerate, amend or change the
period of exercisability or vesting of options or other rights granted under its
stock plans or authorize cash payments in exchange for any options or other
rights granted under any of such plans; or

               (e) ISSUANCE OF SECURITIES. Issue, deliver or sell or authorize
or propose the issuance, delivery or sale of, or purchase or propose the
purchase of, any shares of its capital stock or securities convertible into, or
subscriptions, rights, warrants or options to acquire, or other agreements or
commitments of any character obligating it to issue any such shares or other
convertible securities, other than the issuance of shares of its Common Stock
pursuant to the exercise of stock options, warrants or other rights therefor
outstanding as of the date of this Agreement. Acquiror and Target each
contemplate that they may incur certain indebtedness


                                       32
<PAGE>

(which may be convertible into securities of such corporation and which may
include warrant coverage) for money borrowed prior to the Effective Time. Any
such indebtedness incurred by Target prior to the Effective Time will, by virtue
of the Merger, become indebtedness of the Surviving Corporation. Each of such
parties also contemplates that any such amounts (together with interest) will be
converted into Preferred Stock in the next equity financing consummated by the
Surviving Corporation after the Closing Date. Acquiror and Target also
contemplate that such additional indebtedness will not affect the exchanges
rates in the Merger.

               (f) INTELLECTUAL PROPERTY. Transfer to or license any person or
entity or otherwise extend, amend or modify any rights to
its Intellectual Property other than the grant of non-exclusive licenses in the
ordinary course of business consistent with past practice;

               (g) EXCLUSIVE RIGHTS. Enter into or amend any agreements pursuant
to which any other party is granted exclusive marketing, manufacturing or other
exclusive rights of any type or scope with respect to any of its products or
technology;

               (h) DISPOSITIONS. Sell, lease, license or otherwise dispose of or
encumber any of its properties or assets that are material, individually or in
the aggregate, to its business;

               (i) INDEBTEDNESS. Incur or commit to incur any indebtedness in
excess of $25,000 for borrowed money or guarantee any such indebtedness or issue
or sell any debt securities or guarantee any debt securities of others; provided
that Acquiror may incur such indebtedness if approved the Board of Directors of
Acquiror and Target may incur such indebtedness if approved the Board of
Directors of Target. Acquiror and Target each contemplate that they may incur
certain indebtedness for money borrowed prior to the Effective Time. Any such
indebtedness incurred by Target prior to the Effective Time will, by virtue of
the Merger, become indebtedness of the Surviving Corporation. Each of such
parties also contemplates that any such amounts (together with interest) will be
converted into Preferred Stock in the next equity financing consummated by the
Surviving Corporation after the Closing Date. Acquiror and Target also
contemplate that such additional indebtedness will not affect the exchanges
rates in the Merger.

               (j) LEASES. Enter into any operating lease requiting payments in
excess of $100,000;

               (k) PAYMENT OF OBLIGATIONS. Pay, discharge or satisfy in an

expenditures in excess of $200,000 in the aggregate;

               (n) TERMINATION OR WAIVER. Terminate or waive any right of
substantial value, other than in the ordinary course of business;

               (o) EMPLOYEE BENEFITS; SEVERANCE. Take any of the following
actions: (i) increase or agree to increase the compensation payable or to become
payable to its officers or employees, except for increases in salary or wages of
non-officer employees in the ordinary course of business and in accordance with
past practices, (ii) grant any additional severance or termination pay to, or
enter into any employment or severance agreements with, any officer or employee,
(iii) enter into any collective bargaining agreement, or (iv) establish, adopt,
enter into or amend in any material respect any bonus, profit sharing, thrift,
compensation, stock option, restricted stock, pension, retirement, deferred
compensation, employment, termination, severance or other plan, trust, fund,
policy or arrangement for the benefit of any directors, officers or employees;

immaterial information returns, payroll tax returns or sales tax returns) or any
amendment to a Tax return, enter into any closing agreement, settle any Tax
claim or assessment or consent to any Tax claim or assessment provided that
Acquiror shall not unreasonably withhold or delay approval of any of the
foregoing actions;

               (s) REVALUATION. Revalue any of its assets, including without
limitation writing down the value of inventory or writing off notes or accounts
receivable other than in the ordinary course of business; or

               (t) OTHER. Take, or agree in writing or otherwise to take, any of
the actions described in Sections 4.1(a) through (s) above, or any action that
would make any of its representations or warranties contained in this Agreement

covenants hereunder.

after the execution of this Agreement, Acquiror and Target shall prepare a joint
Information Statement for


                                       34
<PAGE>

their respective shareholders to approve this Agreement, the Agreement of Merger
and the transactions contemplated hereby and thereby. The Information Statement
shall constitute the disclosure document for the offer and issuance of the
shares of Acquiror Common and Preferred Stock to be received by the holders of
Target Capital Stock in the Merger. Each of Acquiror and Target shall use its
best efforts to cause the Information Statement to comply with applicable
federal and state securities laws requirements. Each of Acquiror and Target
agrees to provide promptly to the other such information concerning its business
and financial statements and affairs as, in the reasonable judgment of the
providing party or its counsel, may be required or appropriate for inclusion in
the Information Statement, or in any amendments or supplements thereto, and to
cause its counsel and auditors to cooperate with the other's counsel and
auditors in the preparation of the Information Statement. Target will promptly
advise Acquiror, and Acquiror will promptly advise Target, in writing if at any
time prior to the Effective Time either Target or Acquiror shall obtain
knowledge of any facts that might make it necessary or appropriate to amend or
supplement the Information Statement in order to make the statements contained
or incorporated by reference therein not misleading or to comply with applicable
law. Subject to the provisions of Section 5.1, the Information Statement shall
contain the recommendation of Acquiror's and Target's Boards of Directors that
their respective shareholders approve the Merger and this Agreement and the
conclusion of the Boards of Directors that the terms and conditions of the
Merger are fair and reasonable to each company's shareholders.

          5.2. SHAREHOLDERS MEETING OR CONSENT SOLICITATION. Each of Acquiror
and Target shall promptly after obtaining a permit allowing the issuance of
shares of Acquiror Common and Preferred Stock in exchange for shares of Target
Capital Stock and the assumption of all Target Options and Target Warrant by
Acquiror as contemplated by Section 1.1 hereof take all actions necessary to
either (i) call a meeting of its shareholders to be held for the purpose of
voting upon this Agreement and the Merger or (ii) commence a consent
solicitation to obtain such approvals on or prior to July 31, 1998, or as soon
thereafter as is practicable. Each of Acquiror and Target will, through its
Board of Directors, recommend to its shareholders approval of such matters.

          5.3. ACCESS TO INFORMATION.

               (a) Each of Acquiror and Target shall afford the other party and
the other party's accountants, counsel and other representatives, reasonable
access during normal business hours during the period prior to the Effective
Time to (i) all of Acquiror's or Target's (as the case may be) properties,
books, contracts, commitments and records, and (ii) all other information
concerning the business, properties and personnel of Acquiror or Target (as the
case may be) as Acquiror or Target (as the case may be) may reasonably request.
Each of Acquiror and Target agrees to provide to the other party and its
accountants, counsel and other representatives copies of internal financial
statements promptly upon request.

               (b) Subject to compliance with applicable law, from the date
hereof until the Effective Time, each of Acquiror and Target shall confer on a
regular and frequent basis with one or more representatives of the other party
to report operational matters of materiality and the general status of ongoing
operations.


                                       35
<PAGE>

               (c) No information or knowledge obtained in any investigation
pursuant to this Section 5.3 shall affect or be deemed to modify any
representation or warranty contained herein or the conditions to the obligations
of the parties to consummate the Merger.

          5.4. PUBLIC DISCLOSURE. Unless otherwise permitted by this Agreement,
Acquiror and Target shall consult with each other before issuing any press
release or otherwise making any public statement or making any other public (or
non-confidential) disclosure (whether or not in response to an inquiry)
regarding the terms of this Agreement and the transactions contemplated hereby,
and neither shall issue any such press release or make any such statement or
disclosure without the prior approval of the other (which approval shall not be
unreasonably withheld).

          5.5. CONSENTS; COOPERATION. Each of Acquiror and Target shall promptly
apply for or otherwise seek, and use its best efforts to obtain, all consents
and approvals required to be obtained by it for the consummation of the Merger,
including those required under HSR, and shall use its best efforts to obtain all
necessary consents, waivers and approvals under any of its material contracts in
connection with the Merger for the assignment thereof or otherwise. The parties
hereto will consult and cooperate with one another, and consider in good faith
the views of one another, in connection with any analyses, appearances,
presentations, memoranda, briefs, arguments, opinions and proposals made or
submitted by or on behalf of any party hereto in connection with proceedings
under or relating to HSR or any other federal or state antitrust or fair trade
law.

          5.6. UPDATE DISCLOSURE; BREACHES. From and after the date of this
Agreement until the Effective Time, each party hereto shall promptly notify the
other party, by update to its Disclosure Schedule, of (i) the occurrence or
non-occurrence of any event that would be likely to cause any condition to the
obligations of any party to effect the Merger and the other transactions
contemplated by this Agreement not to be satisfied, or (ii) the failure of
Target or Acquiror, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it pursuant to this
Agreement that would be likely to result in any condition to the obligations of
any party to effect the Merger and the other transactions contemplated by this
Agreement not to be satisfied. The delivery of any notice pursuant to this
Section 5.6 shall not cure any breach of any representation or warranty
requiring disclosure of such matter prior to the date of this Agreement or
otherwise limit or affect the remedies available hereunder to the party
receiving such notice.

          5.7. INDEMNIFICATION.

               (a) From and after the Effective Time, Acquiror and the Surviving
Corporation jointly and severally shall indemnify, defend and hold harmless each
person who is now, or has been at any time prior to the date of this Agreement
or who becomes prior to the Effective Time, an officer, director or employee of
Target (the "INDEMNIFIED PARTIES") in respect of acts or omissions occurring on
or prior to the Effective Time to the extent provided under Target's Articles of
Incorporation, Bylaws and indemnification agreements in effect on the date
hereof; provided that such indemnification shall be subject to any limitation
imposed from time to time under applicable law.


                                       36
<PAGE>

               (b) If Acquiror or the Surviving Corporation or any of their
respective successors or assigns (i) consolidates with or merges into any other
person or entity and shall not be the continuing or surviving person of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person or entity, then and in each such case,
proper provision shall be made so that such successors or assigns of Acquiror or
the Surviving Corporation, as the case may be, shall assume the obligations set
forth in this Section 5.7.

         5.8. LEGAL REQUIREMENTS. Each of Acquiror and Target will take all
reasonable actions necessary to comply promptly with all legal requirements that
may be imposed on them with respect to the consummation of the transactions
contemplated by this Agreement and will promptly cooperate with and furnish
information to any party hereto necessary in connection with any such
requirements imposed upon such other party in connection with the consummation
of the transactions contemplated by this Agreement and will take all reasonable
actions necessary to obtain (and will cooperate with the other parties hereto in
obtaining) any consent, approval, order or authorization of, or any
registration, declaration or filing with, any Governmental Entity or other
person, required to be obtained or made in connection with the taking of any
action contemplated by this Agreement.

         5.9. TAX-FREE REORGANIZATION. Neither Target nor Acquiror will, either
before or after consummation of the Merger, take any action which, to the
knowledge of such party, would cause the Merger to fail to constitute a
"reorganization" within the meaning of Code Section 368.

         5.10. BLUE SKY LAWS. Acquiror shall take such steps as may be
necessary to comply with the securities and blue sky laws of all jurisdictions
that are applicable to the issuance of the Acquiror Common and Preferred Stock
in connection with the Merger. Target shall use its best efforts to assist
Acquiror as may be necessary to comply with the securities and blue sky laws of
all jurisdictions that are applicable in connection with the issuance of
Acquiror Common and Preferred Stock in connection with the Merger.

         5.11. STOCK OPTIONS.

               (a) At the Effective Time, the Target Stock Option Plans and each
outstanding option to purchase shares of Target Common Stock under the Target
Stock Option Plans, whether vested or unvested, shall be assumed by Acquiror.
Target has delivered to Acquiror a schedule in the form attached hereto as
Schedule E (the "OPTION SCHEDULE") that sets forth a true and complete list as
of the date hereof of all holders of outstanding options under the Target Stock
Option Plans, including the number of shares of Target Capital Stock subject to
each such option, the exercise or vesting schedule, the exercise price per share
and the term of each such option. On the Closing Date, Target shall deliver to
Acquiror an updated Option Schedule current as of such date. Each such option so
assumed by Acquiror under this Agreement shall continue to have, and be subject
to, the same terms and conditions set forth in the Target Stock Option Plans
immediately prior to the Effective Time, except that (i) such option shall be
exercisable for that number of whole shares of Acquiror Common Stock equal to
the product of the number of shares of Target Common Stock that were issuable
upon exercise of such option immediately prior to the Effective Time multiplied
by the Common Exchange Ratio and rounded down to the nearest whole number of
shares of Acquiror Common Stock, and


                                       37
<PAGE>

(ii) the per share exercise price for the shares of Acquiror Common Stock
issuable upon exercise of such assumed option shall be equal to the quotient
determined by dividing the exercise price per share of Target Common Stock at
which such option was exercisable immediately prior to the Effective Time by the
Common Exchange Ratio, rounded up to the nearest whole cent. It is the intention
of the parties that the options so assumed by Acquiror qualify following the
Effective Time as incentive stock options as defined in Section 422 of the Code
to the extent such options qualified as incentive stock options prior to the
Effective Time. Within 60 business days after the Effective Time, Acquiror will
issue to each person who, immediately prior to the Effective Time was a holder
of an outstanding option under the Target Stock Option Plans, a document in form
and substance satisfactory to Target evidencing the foregoing assumption of such
option by Acquiror.

               (b) Acquiror shall comply with the terms of the Target Stock
Option Plans and ensure, to the extent required by, and subject to the
provisions of, such Target Stock Option Plan, that Target Stock Options that
qualified as incentive stock options prior the Effective Time continue to
quality as incentive stock options after the Effective Time.

               (c) Acquiror shall take all corporate action necessary to reserve
and make available for issuance a sufficient number of shares of Acquiror Common
Stock for delivery under Target Stock Options assumed in accordance with this
Section 5.11.

          5.12. ADDITIONAL AGREEMENTS; BEST EFFORTS. Each of the parties
agrees to use their best efforts to take, or cause to be taken, all action and
to do, or cause to be done, all things necessary, proper or advisable under
applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement, subject to the appropriate vote of
shareholders of Target and Acquiror, including cooperating fully with the other
party, including by provision of information. In case at any time after the
Effective Time any further action is necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation with full title
to all properties, assets, rights, approvals, immunities and franchises of
either of the constituent corporations, the proper officers and directors of
each party to this Agreement shall take all such necessary action.

          5.13. EMPLOYEE BENEFITS. Acquiror shall take such reasonable
actions, to the extent permitted by Acquiror's benefits program, as are
necessary to allow eligible employees of Target to participate in the benefit
programs of Acquiror, or alternative benefits programs in the aggregate
substantially comparable to those applicable to employees of Acquiror on similar
terms, as soon as practicable after the Effective Time of the Merger. For
purposes of satisfying the terms and conditions of such programs, to the extent
permitted by Acquiror's benefit programs, Acquiror shall use reasonable efforts
to give full credit for eligibility, or vesting for each participant's period of
service with Target.

governmental authority or instrumentality, domestic or foreign, seeking any of
the foregoing be pending; nor shall there be any action taken, or any statute,
rule, regulation or order enacted, entered, enforced or deemed applicable to the

reasonable diligent efforts to have such injunction or other order lifted;

obtain such consents or approvals would or would reasonably be expected to have
a Material Adverse Effect on Target.

               (d) INJUNCTIONS OR RESTRAINTS ON MERGER AND CONDUCT OF BUSINESS.
No proceeding brought by any administrative agency or commission or other
governmental authority or instrumentality, domestic or foreign, seeking to
prevent the consummation of the Merger shall be pending. In addition, no
temporary restraining order, preliminary or permanent injunction or other order
issued by any court of competent jurisdiction or other legal or regulatory
restraint provision limiting or restricting Acquiror's conduct or operation of
the business of Target following the Merger shall be in effect, nor shall any
proceeding brought by an administrative agency or commission or other
Governmental Entity, domestic or foreign, seeking the foregoing be pending.

               (e) NO MATERIAL ADVERSE CHANGES. There shall not have occurred
any material adverse change in the condition (financial or otherwise),
properties, assets (including intangible assets), liabilities, business,
operations, results of operations or prospects of Target.

               (f) FIRPTA CERTIFICATE. Target shall, prior to the Closing Date,
provide Acquiror with a properly executed FIRPTA Notification Letter,
substantially in the form of EXHIBIT D attached hereto, which states that shares
of capital stock of Target do not constitute "United States real property
interests" under Section 897(c) of the Code, for purposes of satisfying
Acquiror's obligations under Treasury Regulation Section 1.1445-2(c)(3). In
addition, simultaneously with delivery of such Notification Letter, Target shall
have provided to Acquiror, as agent for Target, a form of notice to the Internal
Revenue Service in accordance with the requirements of Treasury Regulation
Section 1.897-2(h)(2) and substantially in the form of EXHIBIT D attached hereto
along with written authorization for Acquiror to deliver such notice form to the
Internal Revenue Service on behalf of Target upon the Closing of the Merger.

               (g) RESIGNATION OF DIRECTORS. The directors of Target in office
immediately prior to the Effective Time shall have resigned as directors of
Target effective as of the Effective Time.

               (h) TERMINATION OF WARRANTS. The holders of a majority of the
Warrants to purchase an aggregate of 419,268 shares of Target Common Stock
issued in connection with Target's June 1996 bridge financing shall have voted
to terminate each of the warrants issued in such financing.

cured within five (5) business days of receipt by Target of written notice of

to terminate this Agreement by Target under this Section 7.1(d)(iii) shall not
be available to Target where Target is at that time in material breach of this

                                       42
<PAGE>

               (e) by Acquiror if (i) any permanent injunction or other order of
a court or other competent authority preventing the consummation of the Merger
shall have become final and nonappealable or (ii) if any required approval of
the shareholders of Target or Acquiror shall not have been obtained by reason of
the failure to obtain the required shareholder consents within 20 days of the
commencement of a shareholder consent solicitation or vote upon a vote held at a
duly held meeting of shareholders or at any adjournment thereof; or

               (f) by Target if (i) any permanent injunction or other order of a

Agreement as provided in Section 7.1, this Agreement shall forthwith become void

                                  ARTICLE VIII

                                 INDEMNIFICATION

          8.1. SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.
Notwithstanding any investigation conducted before or after the Closing Date,
Acquiror, Target and the holders of Target Capital Stock (collectively, the
"FORMER TARGET SHAREHOLDERS") will be entitled to rely upon the other party's
(including those made by certain shareholders of the other party),
representations, warranties and covenants set forth in this Agreement. The
obligations of Acquiror, the Acquiror Shareholders, Target and the Target
Shareholders with respect to its representations, warranties, agreements and
covenants will survive the Closing and continue in full force and effect until
the date twelve (12) months following the Closing Date (the "TERMINATION DATE"),
provided that any claim for indemnification made prior to the end of such twelve
(12) month period following the Closing Date shall survive until paid or
otherwise resolved in accordance with the terms of this Agreement.

          8.2. INDEMNITY BY TARGET SHAREHOLDERS. From and after the Effective
Time of the Merger, and subject to the other provisions of this Section 8,
Acquiror (on or after the Closing Date) shall be indemnified and held harmless
by the Target Shareholders against, and reimbursed for, any actual liability,
damage, loss, obligation, demand, judgment, fine, penalty, cost or expense
(excluding any indirect or consequential damages to Acquiror, other than any
such damages resulting from injunctive relief granted as to an intellectual
property claim), including reasonable attorneys' fees and expenses, and the
costs of investigation incurred in defending against or settling such liability,
damage, loss, cost or expense or claim therefor and any amounts paid in
settlement thereof) imposed on or reasonably incurred by Acquiror as a result of
any breach of any representation, warranty, agreement or covenant on the part of
Target or the Target Shareholders under this agreement (collectively the
"ACQUIROR DAMAGES"). Notwithstanding any of the foregoing, the Target
Shareholders shall NOT have any indemnification obligation to Acquiror as a
result of any breach of any representation, warranty, agreement or covenant on
the part of Target or the Target Shareholders under this Agreement if, at the
time that this Agreement was executed or at the Effective Time, William Gibson
or Charles Pai knew, or reasonably should have known, that such representation,
warranty, agreement or covenant was inaccurate or not complied with. Acquiror
Damages in each case shall be net of the amount of any insurance proceeds,
indemnity and contribution actually recovered by Acquiror. "Acquiror Damages" as
used herein is not limited to matters asserted by third parties, but includes
Damages incurred or sustained by Acquiror in the absence of claims by a third
party.

          8.3. INDEMNITY BY ACQUIROR AND ACQUIROR SHAREHOLDERS. From and after
the Effective Time of the Merger, and subject to the other provisions of this
Section 8, the Former Target Shareholders (on or after the Closing Date) shall
be indemnified and held harmless by the Acquiror and the Acquiror Shareholders
against, and reimbursed for, any actual liability, damage, loss, obligation,
demand, judgment, fine, penalty, cost or expense (excluding any indirect or
consequential damages to the Former Target Shareholders, other than any such
damages resulting from injunctive relief granted as to an intellectual property
claim), including reasonable attorneys' fees and expenses, and the costs of
investigation incurred in defending against or settling such liability, damage,
loss, cost or expense or claim therefor and any amounts


                                       44
<PAGE>

paid in settlement thereof) imposed on or reasonably incurred by the Former
Target Shareholders as a result of any breach of any representation, warranty,
agreement or covenant on the part of Acquiror or the Acquiror Shareholders under
this Agreement (Collectively the "FORMER TARGET SHAREHOLDERS DAMAGES"). Former
Target Shareholders Damages in each case shall be net of the amount of any
insurance proceeds, indemnity and contribution actually recovered by the Former
Target Shareholders. "Former Target Shareholders Damages" as used herein is not
limited to matters asserted by third parties, but includes Damages incurred or
sustained by the Former Target Shareholders in the absence of claims by a third
party. For purposes of this Section 8, the term "Damages" shall mean Acquiror
Damages or Former Target Shareholders Damages, as the case may be.

          8.4. DAMAGE THRESHOLD. Notwithstanding the foregoing, neither Acquiror
nor the Former Target Shareholders may receive indemnification for any Damages
pursuant to this Section 8 unless and until the amount of the Damages sustained
by Acquiror or all Former Target Shareholders, as the case may be, shall exceed
$1,000,000 (the "Damage Threshold Amount"). Once the aggregate claims reach the
Damage Threshold Amount, the indemnitees shall be liable for all such claims,
excluding amounts required to reach the Damage Threshold Amount, subject to the
damage limitations contained in Section 8.5.

          8.5. DAMAGE LIMITATIONS; LIMITATION ON REMEDIES. The ability of the
Acquiror and of the Former Target Shareholders to make claims for
indemnification against the Acquiror Shareholders or the Target Shareholders
pursuant to this Section shall be limited (i) in the case of the Acquiror
Shareholders, to the shares of capital stock of Acquiror held by such Acquiror
Shareholders at the Effective Time, and (ii) in the case of the Target
Shareholders, to the shares of capital stock of Acquiror held by such Target
Shareholders immediately after the Effective Time. The indemnification
obligations of the Target Shareholders and of the Acquiror Shareholders
described in the preceding sentence shall be the sole and exclusive obligations
of the Target Shareholders and of the Acquiror Shareholders with respect to any
representation, warranty, covenant or agreement made by Target, the Target
Shareholders, Acquiror or the Acquiror Shareholders under this Agreement and no
former shareholder, optionholder, warrantholder, director, officer, employee or
agent of Target or Acquiror shall have any other personal liability to Acquiror
or the Former Target Shareholders after the Closing in connection with the
Merger. In no event shall the indemnification obligations of (a) Acquiror and
the Acquiror Shareholders exceed a maximum of $2,000,000 in the aggregate (the
"Acquiror's Aggregate Indemnification Obligation") or (b) the Target
Shareholders exceed a maximum of $2,000,000 in the aggregate (the "Target
Shareholders' Aggregate Indemnification Obligation"). Moreover, the
indemnification obligations of the Target Shareholders and the Acquiror
Shareholders shall be limited to their Acquiror Common Stock and Acquiror
Preferred Stock, which Acquiror Common Stock and Acquiror Preferred Stock shall
be deemed to have a value of $2.50 per share for purposes of the $2,000,000
ceiling on liability described in the preceding sentence. The parties to this
Agreement agree that the per share price described in the preceding sentence was
determined without implication on the actual fair market value of the Acquiror's
Common Stock or Preferred Stock at or after the Closing Date, such amount being
selected by the parties hereto for purposes of administrative convenience in
applying the indemnification provisions of this Section 8. Each particular
Target Shareholder's indemnity obligation shall not exceed such Target
Shareholder's pro rata share (as described below) of the difference between the
Acquiror Damages and the Damage Threshold Amount (the "Net Acquiror Damages"),


                                       45
<PAGE>

which Net Acquiror Damages in the aggregate shall not exceed the Target
Shareholders' Aggregate Indemnification Obligation. Such Target Shareholder's
pro rata share of the Net Acquiror Damages shall be determined by multiplying
the Net Acquiror Damages by a fraction, the numerator of which shall be the
number of shares of Target Common Stock and Preferred Stock held by such Target
Shareholder at the Effective Time (on an as-converted basis) and the denominator
of which shall be the total number of shares of Target Common and Preferred
Stock held by all Target Shareholders at the Effective Time (on an as-converted
basis). Each particular Acquiror Shareholder's indemnity obligation shall not
exceed such Acquiror Shareholder's pro rata share (as described below) of the
difference between the Former Target Shareholders Damages and the Damage
Threshold (the "Net Former Target Shareholders Damages"), which Net Former
Target Shareholders Damages in the aggregate shall not exceed the Acquiror
Aggregate Indemnification Obligation. Such Acquiror Shareholder's pro rata share
of the Net Former Target Shareholders Damages shall be determined by multiplying
the Net Former Target Shareholders Damages by a fraction, the numerator of which
shall be the number of shares of Acquiror Common Stock and Preferred Stock held
by such Acquiror Shareholder at the Effective Time (on an as-converted basis)
and the denominator of which shall be the total number of shares of Acquiror
Common and Preferred Stock held by all Acquiror Shareholders at the Effective
Time (on an as-converted basis). The Former Target Shareholders shall be
entitled to seek indemnification from either Acquiror or the Acquiror
Shareholders, or a combination of both, at the discretion of the Former Target
Shareholders.

          8.6. RESTRICTIONS ON TRANSFER ACQUIROR SHAREHOLDERS AND TARGET
SHAREHOLDERS. Each Acquiror Shareholder and Target Shareholder agrees that,
during the period specified in Section 8.1 during which such shareholder may
potentially have an indemnification obligation under this Section 8, it shall
not directly or indirectly sell, offer to sell, contract to sell, grant any
option to purchase or otherwise transfer or dispose of (other than to a
transferee who agrees to be bound by the indemnification obligations of this
Section 8) any Acquiror Common Stock or Acquiror Preferred Stock owned by such
shareholder at the Effective Time. In order to enforce the foregoing covenant,
the Acquiror may impose stop-transfer instructions with respect to the Acquiror
Stock of each Acquiror Shareholder and Target Shareholder until the end of such
period.

                                   ARTICLE IX

          9.2. INTERPRETATION. When a reference is made in this Agreement to
Exhibits, such reference shall be to an Exhibit to this Agreement unless
otherwise indicated. The words "include," "includes" and "including" when used
herein shall be deemed in each case to be followed by the words "without
limitation." In this Agreement, any reference to any event, change, condition or
effect being "material" with respect to any entity or group of entities means
any material event, change, condition or effect related to the condition
(financial or otherwise), properties, assets (including intangible assets),
liabilities, business, operations or results of operations of such entity or
group of entities. In this Agreement, any reference to a "Material Adverse
Effect" with respect to any entity or group of entities means any event, change
or effect that is materially adverse to the condition (financial or otherwise),
properties, assets (including intangible assets), liabilities, business,
operations or results of operations of such entity and its subsidiaries, taken
as a whole. In this Agreement, any reference to a party's "knowledge" means such
party's actual knowledge after due and diligent inquiry of officers, directors
and other employees of such party and its subsidiaries reasonably believed to
have knowledge of such matters. The phrase "made available" in this Agreement
shall mean that the information referred to has been made available if requested
by the party to whom such information is to be made


                                       47
<PAGE>

available. The phrases "the date of this Agreement," "the date hereof," and
terms of similar import, unless the context otherwise requires, shall be deemed
to refer to June 4, 1998. The table of contents and headings contained in this
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

          9.3. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

          9.4. ENTIRE AGREEMENT; NO THIRD PARTY BENEFICIARIES. This Agreement,
the other Transaction Documents and the documents and instruments and other
agreements specifically referred to herein or delivered pursuant hereto,
including the Exhibits, the Schedules, including the Target Disclosure Schedule
and the Acquiror Disclosure Schedule constitute the entire agreement among the
parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter hereof.

          9.5. SEVERABILITY. In the event that any provision of this Agreement,
or the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision that will achieve, to the extent possible, the economic,
business and other purposes of such void or unenforceable provision.

          9.6. REMEDIES CUMULATIVE. Except as otherwise provided herein, any and
all remedies herein expressly conferred upon a party will be deemed cumulative
with and not exclusive of any other remedy conferred hereby, or by law or equity
upon such party, and the exercise by a party of any one remedy will not preclude
the exercise of any other remedy.

          9.7. GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the laws of the State of California without regard to
applicable principles of conflicts of law. Each of the parties hereto
irrevocably consents to the exclusive jurisdiction of any court located within
the State of California, in connection with any matter based upon or arising out
of this Agreement or the matters contemplated herein, agrees that process may be
served upon them in any manner authorized by the laws of the State of California
for such persons and waives and covenants not to assert or plead any objection
which they might otherwise have to such jurisdiction and such process.

          9.8. ASSIGNMENT. Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned by any of the parties
hereto (whether by operation of law or otherwise) without the prior written
consent of the other parties. Subject to the preceding sentence, this Agreement
will be binding upon, inure to the benefit of and be enforceable by the parties
and their respective successors and permitted assigns.

          9.9. RULES OF CONSTRUCTION. The parties hereto agree that they
have been represented by counsel during the negotiation, preparation and
execution of this Agreement and, therefore, waive the application of any law,
regulation, holding or role of construction providing that ambiguities in an
agreement or other document will be construed against the party drafting such
agreement or document.

the issue of that series, but not below the number of shares of such series then
outstanding. In case the number of shares of any series shall be so decreased,
the shares constituting such decrease shall resume the status which they had
prior to the adoption of the resolution originally fixing the number of shares
of such series.

                                   ARTICLE V

                  In furtherance and not in limitation of the powers conferred
by statute, the Board of Directors is expressly authorized to make, repeal,
alter, amend and rescind any or all of the Bylaws of the Corporation. In
addition, the Bylaws may be amended by the affirmative vote of holders of at
least sixty-six and two-thirds percent (66 2/3%) of the outstanding shares of
voting stock of the Corporation entitled to vote at an election of directors.

                                   ARTICLE VI

                  The number of directors of the Corporation shall be determined
by resolution of the Board of Directors.

                  Elections of directors need not be by written ballot unless
the Bylaws of the Corporation shall so provide. Advance notice of stockholder
nominations for the election of directors and of any other business to be
brought before any meeting of the stockholders shall be given in the manner
provided in the Bylaws of this Corporation.

                  At each annual meeting of stockholders, directors of the
Corporation shall be elected to hold office until the expiration of the term for
which they are elected, or until their successors have been duly elected and
qualified; except that if any such election shall not be so held, such election
shall take place at a stockholders' meeting called and held in accordance with
the GCL.

                  The directors of the Corporation shall be divided into three
(3) classes as nearly equal in size as is practicable, hereby designated Class
I, Class II and Class III. For the purposes hereof, the initial Class I, Class
II and Class III directors shall be those directors so designated by a
resolution of the Board of Directors. At the first annual meeting of
stockholders following the closing of the initial public offering of the
Corporation's Common Stock, the term of office of the Class I directors shall
expire and Class I directors shall be elected for a full term of three (3)
years. At the second annual meeting of stockholders following the closing of the
initial public offering of the Corporation's Common Stock, the term of office of
the Class II directors shall


                                      -2-
<PAGE>


expire and Class II directors shall be elected for a full term of three (3)
years. At the third annual meeting of stockholders following the initial public
offering of the Corporation's Common Stock, the term of office of the Class III
directors shall expire and Class III directors shall be elected for a full term
of three (3) years. At each succeeding annual meeting of stockholders, directors
shall be elected for a full term of three (3) years to succeed the directors of
the class whose terms expire at such annual meeting. If the number of directors
is hereafter changed, each director then serving as such shall nevertheless
continue as a director of the Class of which he is a member until the expiration
of his current term and any newly created directorships or decrease in
directorships shall be so apportioned among the classes as to make all classes
as nearly equal in number as is practicable.

                  Vacancies occurring on the Board of Directors for any reason
may be filled by vote of a majority of the remaining members of the Board of
Directors, even if less than a quorum, at any meeting of the Board of Directors.
A person so elected by the Board of Directors to fill a vacancy shall hold
office for the remainder of the full term of the director for which the vacancy
was created or occurred and until such director's successor shall have been duly
elected and qualified. A director may be removed from office by the affirmative
vote of the holders of 66 2/3% of the outstanding shares of voting stock of the
Corporation entitled to vote at an election of directors, provided that such
removal is for cause.

                                  ARTICLE VII

                  Stockholders of the Corporation shall take action by meetings
held pursuant to this Amended and Restated Certificate of Incorporation and the
Bylaws and shall have no right to take any action by written consent without a
meeting. Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide. Special meetings of the stockholders, for
any purpose or purposes, may only be called by the Board of Directors of the
Corporation. The books of the Corporation may be kept (subject to any provision
contained in the statutes) outside the State of Delaware at such place or places
as may be designated from time to time by the Board of Directors or in the
Bylaws of the Corporation.

                                  ARTICLE VIII

                  To the fullest extent permitted by applicable law, this
Corporation is authorized to provide indemnification of (and advancement of
expenses to) directors, officers, employees and agents (and any other persons to
which Delaware law permits this Corporation to provide indemnification) through
Bylaw provisions, agreements with such agents or other persons, vote of
stockholders or disinterested directors or otherwise, in excess of the
indemnification and advancement otherwise permitted by Section 145 of the GCL,
subject only to limits created by applicable Delaware law (statutory or
non-statutory), with respect to action for breach of duty to the Corporation,
its stockholders, and others.

                  No director of the Corporation shall be personally liable to
the Corporation or any stockholder for monetary damages for breach of fiduciary
duty as a director, except for any matter in respect of which such director
shall be liable under Section 174 of the GCL or any amendment thereto or shall
be liable by reason that, in addition to any and all other requirements for such
liability, such director (1) shall have breached the director's duty or loyalty
to the


                                      -3-
<PAGE>

Corporation or its stockholders, (2) shall have acted in manner involving
intentional misconduct or a knowing violation of law or, in failing to act,
shall have acted in a manner involving intentional misconduct or a knowing
violation of law, or (3) shall have derived an improper personal benefit. If the
GCL is hereafter amended to authorize the further elimination or limitation of
the liability of a director, the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the GCL, as so
amended.

                  Each person who was or is made a party or is threatened to be
made a party to or is in any way involved in any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), including any appeal therefrom, by
reason of the fact that he or she, or a person of whom he or she is the legal
representative, is or was a director or officer of the Corporation or a direct
or indirect subsidiary of the Corporation, or is or was serving at the request
of the Corporation as a director or officer of another entity or enterprise, or
was a director or officer of a foreign or domestic corporation which was
predecessor corporation of the Corporation or of another entity or enterprise at
the request of such predecessor corporation, shall be indemnified and held
harmless by the Corporation, and the Corporation shall advance all expenses
incurred by any such person in defense of any such proceeding prior to its final
determination, to the fullest extent authorized by the GCL. In any proceeding
against the Corporation to enforce these rights, such person shall be presumed
to be entitled to indemnification and the Corporation shall have the burden of
proving that such person has not met the standards of conduct for permissible
indemnification set forth in the GCL. The rights to indemnification and
advancement of expenses conferred by this Article VIII shall be presumed to have
been relied upon by the directors and officers of the Corporation in serving or
continuing to serve the Corporation and shall be enforceable as contract rights.
Said rights shall not be exclusive of any other rights to which those seeking
indemnification may otherwise be entitled. The Corporation may, upon written
demand presented by a director or officer of the Corporation or of a direct or
indirect subsidiary of the Corporation, or by a person serving at the request of
the Corporation as a director or officer of another entity or enterprise, enter
into contracts to provide such persons with specified rights to indemnification,
which contracts may confer rights and protections to the maximum extent
permitted by the GCL, as amended and in effect from time to time.

                  If a claim under this Article VIII is not paid in full by the
Corporation within sixty (60) days after a written claim has been received by
the Corporation, the claimant may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part, the claimant shall be entitled to be paid also the expenses of
prosecuting such claim. It shall be a defense to any such action (other than an
action brought to enforce the right to be advanced expenses incurred in
defending any proceeding prior to its final disposition where the required
undertaking, if any, has been tendered to the Corporation) that the claimant
has not met the standards of conduct which make it permissible under the GCL for
the Corporation to indemnify the claimant for the amount claimed, but the
claimant shall be presumed to be entitled to indemnification and the Corporation
shall have the burden of proving that the claimant has not met the standards of
conduct for permissible indemnification set forth in the GCL.

                  If the GCL is hereafter amended to permit the Corporation to
provide broader indemnification rights than said law permitted the Corporation
to provide prior to such amendment, the indemnification rights conferred by this
Article VIII shall be broadened to the fullest extent permitted by the GCL, as
so amended.

                                   ARTICLE IX

                  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Amended and Restated Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all
rights conferred upon stockholders herein are granted subject to this
reservation. Notwithstanding the foregoing, the provisions set forth in Articles
V, VI, VII, VIII and IX of this Amended and Restated Certificate of
Incorporation may not be repealed or amended in any respect without the
affirmative vote of holders at least 66-2/3% of the outstanding voting stock of
the Corporation entitled to vote at election of directors.

                  FOUR: The foregoing amendment and restatement has been duly
adopted by the Corporation's Board of Directors in accordance with the
applicable provisions of Sections 242 and 245 of the General Corporation Law of
the State of Delaware.

                  FIFTH: The foregoing amendment and restatement was approved by
the holders of the requisite number of shares of the Corporation in accordance
with Section 228 of the General Corporation Law of the State of Delaware.

                  IN WITNESS WHEREOF, the undersigned have executed this
certificate on ____________, 2000.

                  Notwithstanding anything in these Bylaws to the contrary, no
business shall be conducted at a meeting except in accordance with the

was not properly brought before the meeting and in accordance with the
procedures prescribed by this Section 12, and if such person should so
determine, such person shall so declare to the meeting and any such business not

                                   ARTICLE III

                                    DIRECTORS

                  SECTION 1. The number of directors of this corporation that
shall constitute the whole board shall be determined by resolution of the Board
of Directors; provided, however, that no decrease in the number of directors
shall have the effect of shortening the term of an incumbent director. The Board
of Directors shall be classified, with respect to the time for which they
severally hold office, into three classes, as nearly equal in number as
possible, as determined by the Board of Directors, one class to hold office
initially for a term expiring at the


                                       6
<PAGE>

annual meeting to be held in 2000, another class to hold office initially for a
term expiring at the annual meeting of stockholders held in 2001 and another
class to hold office initially for a term expiring at the annual meeting of
stockholders to be held in 2002, with the members of each class to hold office
until their successors are elected and qualified. At each annual meeting of
stockholders, the successors of the class of directors whose term expires at
that meeting shall be elected to hold office for a term expiring at the annual
meeting of stockholders held in the third year following the year of their
election.

                  SECTION 2. Vacancies and newly created directorships resulting
from any increase in the authorized number of directors may be filled by a
majority of the directors then in office, even if less than a quorum, or by a
sole remaining director, and the directors so chosen shall hold office until the
next election of the class for which such directors were chosen and until their
successors are duly elected and qualified or until earlier resignation or
removal. If there are no directors in office, then an election of directors may
be held in the manner provided by statute.

                  SECTION 3. The business of the corporation shall be managed by
or under the direction of its Board of Directors which may exercise all such
powers of the corporation and do all such lawful acts and things as are not by
statute or by the certificate of incorporation or by these bylaws directed or
required to be exercised or done by the stockholders.

                       MEETINGS OF THE BOARD OF DIRECTORS

                  SECTION 4. The Board of Directors of the corporation may hold
meetings, both regular and special, either within or without the State of
Delaware.

                  SECTION 5. The first meeting of each newly elected Board of
Directors shall be held at such time and place as shall be fixed by the vote of
the stockholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to


                                       7
<PAGE>

constitute the meeting, provided a quorum shall be present. In the event of the
failure of the stockholders to fix the time or place of such first meeting of
the newly elected Board of Directors, or in the event such meeting is not held
at the time and place so fixed by the stockholders, the meeting may be held at
such time and place as shall be specified in a notice given as hereinafter
provided for special meetings of the Board of Directors, or as shall be
specified in a written waiver signed by all of the directors.

                  SECTION 6. Regular meetings of the Board of Directors may be
held without notice at such time and at such place as shall from time to time be
determined by the board.

                  SECTION 7. Special meetings of the board may be called by the
Chairman of the Board or the president on twelve (12) hours' notice to each
director by phone, fax or electronic mail; special meetings shall be called by
the Chairman of the Board, the president or secretary in like manner and on like
notice on the written request of a majority of the Board unless the Board
consists of only one director, in which case special meetings shall be called by
the Chairman of the Board, the president or secretary in like manner and on like
notice on the written request of the sole director.

                  SECTION 8. At all meetings of the board a majority of the
directors shall constitute a quorum for the transaction of business and the act
of a majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the certificate of incorporation. If a
quorum shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

                  SECTION 9. Unless otherwise restricted by the certificate of
incorporation or these bylaws, any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting, if all members of the board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the board or committee.

                  SECTION 10. Unless otherwise restricted by the certificate of
incorporation or these bylaws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other, and such participation in a meeting shall

board may designate one (1) or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of

authority of the Board of Directors in

recommending to the stockholders the sale, lease or exchange of all or
substantially all of the corporation's property and assets, recommending to the

fact by the person claiming the certificate of stock to be lost, stolen or
destroyed. When authorizing such issue of a new certificate or certificates, the
Board of Directors may, in its discretion and as a condition precedent to the

certificate or certificates, or his/her legal representative, to advertise the
same in such manner as it shall require and/or to give the corporation a bond in
such sum as it may direct as indemnity against any claim that may be made
against the corporation with respect to the certificate alleged to have been
lost, stolen or destroyed.

respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty (60) nor less than ten (10) days before the

determination of stockholders of record entitled to notice of or


                                       17
<PAGE>

to vote at a meeting of stockholders shall apply to any adjournment of the

                  SECTION 5. The corporation shall be entitled to recognize the
exclusive right of a person registered on its books as the owner of shares to
receive dividends, and to vote as such owner, and to hold liable for calls and
assessments a person registered on its books as the owner of shares and shall

aside out of any funds of the corporation available for dividends such sum or
sums as the directors from time to time, in their absolute discretion, think
proper as a reserve or reserves to meet contingencies, or for equalizing

for such other purposes as the directors shall think conducive to the interest
of the corporation, and the directors may modify or abolish any such reserve in

having inscribed thereon the name of the corporation, the year of its

causing it or a facsimile thereof to be impressed or affixed or reproduced or
otherwise.

                                 INDEMNIFICATION

                  SECTION 6. The corporation shall, to the fullest extent
authorized under the laws of the State of Delaware, as those laws may be amended
and supplemented from time to time, indemnify any director made, or threatened
to be made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director of the
corporation or a predecessor corporation or, at the corporation's request, a
director or officer of another corporation, provided, however, that the
corporation shall indemnify any such agent in connection with a proceeding
initiated by such agent only if such proceeding was authorized by the Board of
Directors of the corporation. The indemnification provided for in this Section 6
shall: (i) not be deemed exclusive of any other rights to which those
indemnified may be entitled under any bylaw, agreement or vote of stockholders
or disinterested directors or otherwise, both


                                       19
<PAGE>

as to action in their official capacities and as to action in another capacity
while holding such office, (ii) continue as to a person who has ceased to be a
director, and (iii) inure to the benefit of the heirs, executors and
administrators of such a person. The corporation's obligation to provide
indemnification under this Section 6 shall be offset to the extent of any other
source of indemnification or any otherwise applicable insurance coverage under a
policy maintained by the corporation or any other person.

                  Expenses incurred by a director of the corporation in
defending a civil or criminal action, suit or proceeding by reason of the fact
that he is or was a director of the corporation (or was serving at the
corporation's request as a director or officer of another corporation) shall be
paid by the corporation in advance of the final disposition of such action, suit
or proceeding upon receipt of an undertaking by or on behalf of such director to
repay such amount if it shall ultimately be determined that he is not entitled
to be indemnified by the corporation as authorized by relevant sections of the
General Corporation Law of Delaware. Notwithstanding the foregoing, the
corporation shall not be required to advance such expenses to an agent who is a
party to an action, suit or proceeding brought by the corporation and approved
by a majority of the Board of Directors of the corporation which alleges willful
misappropriation of corporate assets by such agent, disclosure of confidential
information in violation of such agent's fiduciary or contractual obligations to
the corporation or any other willful and deliberate breach in bad faith of such
agent's duty to the corporation or its stockholders.

                  The foregoing provisions of this Section 6 shall be deemed to
be a contract between the corporation and each director who serves in such
capacity at any time while this bylaw is in effect, and any repeal or
modification thereof shall not affect any rights or obligations then existing
with respect to any state of facts then or theretofore existing or any action,
suit or


                                       20
<PAGE>

proceeding theretofore or thereafter brought based in whole or in part upon any
such state of facts.

                  The Board of Directors in its discretion shall have power on
behalf of the corporation to indemnify any person, other than a director, made a
party to any action, suit or proceeding by reason of the fact that he, his
testator or intestate, is or was an officer or employee of the corporation.

                  To assure indemnification under this Section 6 of all
directors, officers and employees who are determined by the corporation or
otherwise to be or to have been "fiduciaries" of any employee benefit plan of
the corporation which may exist from time to time, Section 145 of the General
Corporation Law of Delaware shall, for the purposes of this Section 6, be
interpreted as follows: an "other enterprise" shall be deemed to include such an
employee benefit plan, including without limitation, any plan of the corporation
which is governed by the Act of Congress entitled "Employee Retirement Income
Security Act of 1974," as amended from time to time; the corporation shall be
deemed to have requested a person to serve an employee benefit plan where the
performance by such person of his duties to the corporation also imposes duties
on, or otherwise involves services by, such person to the plan or participants
or beneficiaries of the plan; excise taxes assessed on a person with respect to
an employee benefit plan pursuant to such Act of Congress shall be deemed
"fines."

                                  ARTICLE VIII

                                   AMENDMENTS

                  SECTION 1. These bylaws may be altered, amended or repealed or
new bylaws may be adopted by the affirmative vote of holders of at least 66-2/3%
vote of the outstanding voting stock of the corporation. These bylaws may also
be altered, amended or repealed or new bylaws


                                       21
<PAGE>

may be adopted by the Board of Directors, when such power is conferred upon the
Board of Directors by the certificate of incorporation. The foregoing may occur
at any regular meeting of the stockholders or of the Board of Directors or at
any special meeting of the stockholders or of the Board of Directors if notice
of such alteration, amendment, repeal or adoption of new bylaws be contained in
the notice of such special meeting. If the power to adopt, amend or repeal
bylaws is conferred upon the Board of Directors by the certificate of
incorporation it shall not divest or limit the power of the stockholders to
adopt, amend or repeal bylaws.

months after the effective date of the first registration statement filed by the

of the Registrable Securities having a reasonably anticipated aggregate offering
price, net of underwriting discounts and commissions, that exceeds $10,000,000,
the Company will:

                 (i) promptly give written notice of the proposed registration
to all other Holders; and

                 (ii) as soon as practicable, use its diligent best efforts to
effect such registration (including, without limitation, filing post-effective

securities laws and appropriate compliance with the Securities Act) as would

such portion of the Registrable Securities of any Holder or Holders joining in
such request as are specified in a written request received by the Company
within twenty (20) days after such written notice from the Company is effective.

         The Company shall not be obligated to effect, or to take any action to
effect, any such registration pursuant to this Section 1.2:

                      (A) In any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                      (B) After the Company has effected three such
registrations pursuant to this Section 1.2(a) and such registrations have been
declared or ordered effective; further, with respect to the second of such
registrations, the Company need take no action pursuant to this Section 1.2
within one year of the date the first has been declared or ordered effective;

                      (C) During the period starting with the date sixty (60)
days prior to the Company's good faith estimate of the date of filing of, and
ending on a date one hundred eighty (180) days after the effective date of, a
registration pursuant to Section 1.3 hereof; provided that the Company is
actively employing in good faith all reasonable efforts to cause such
registration statement to become effective;

                      (D) If the Initiating Holders propose to dispose of shares

                                       7
<PAGE>

concludes, as a result, that it is essential to defer the filing of such
registration statement at such time, and (ii) the Company shall furnish to such
Holders a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company for such registration statement to be filed
in the near future and that it is, therefore, essential to defer the filing of
such registration statement, then the Company shall have the right to defer such
filing for the period during which such disclosure would be seriously
detrimental, provided, that the Company may not defer the filing for a period of
more than sixty (60) days after receipt of the request of the Initiating
Holders, and, provided further, that (except as provided in clause (C) above)
the Company shall not defer its obligation in this manner more than once in any
twelve-month period.

         The registration statement filed pursuant to the request of the
Initiating Holders may, subject to the provisions of Sections 1.2(d) and 1.16
hereof, include other securities of the Company and may include securities of
the Company being sold for the account of the Company.

         (c) UNDERWRITING. If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
Section 1.2 and the Company shall include such information in the written notice
referred to in Section 1.2(a)(i) above. The right of any Holder to registration
pursuant to Section 1.2 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders and such Holder with respect to such participation and
inclusion) to the extent provided herein.

         (d) PROCEDURES. If the Company shall request inclusion in any
registration pursuant to Section 1.2 of securities being sold for its own
account, or if other Holders shall request inclusion in any registration
pursuant to Section 1.2, the Initiating Holders shall, on behalf of all Holders,
offer to include such securities in the underwriting and may condition such
offer on their acceptance of the further applicable provisions of this Section
1. The Company shall (together with all Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with the representative of the underwriter or underwriters
selected for such underwriting by a majority in interest of the Initiating
Holders, which underwriter(s) shall be reasonably acceptable to the Company.
Notwithstanding any other provision of this Section 1.2, if the representative
of the underwriters advises the Initiating Holders in writing that marketing
factors require a limitation on the number of shares to be underwritten, the
number of shares to be included in the underwriting or registration shall be
allocated as set forth in Section 1.16 hereof. If a Holder who has requested
inclusion in such registration as provided above does not agree to the terms of
any such underwriting, such Holder shall be excluded therefrom by written notice
from the Company, the underwriter or the Initiating Holders. The securities so
excluded pursuant to Section 1.16 shall also be withdrawn from registration. Any
Registrable Securities or other securities excluded shall also be withdrawn from
such registration. If shares are so withdrawn from the registration and if the
number of shares to be included in such registration was previously reduced as a
result of marketing factors pursuant to this Section 1.2(d), then the Company
shall offer to all Holders who have retained rights to include securities in the
registration the right to include additional securities in the registration in
an aggregate amount equal to the number of shares withdrawn,


                                       8
<PAGE>

with such shares to be allocated among such Holders requesting additional
inclusion in accordance with Section 1.16.

         1.3 COMPANY REGISTRATION.

             (a) If the Company shall determine to register any of its
securities either for its own account or the account of a security holder or
holders exercising their respective demand registration rights (other than
pursuant to Section 1.2 hereof), other than a registration relating solely to
employee benefit plans, or a registration relating solely to a Commission Rule
145 transaction, or a registration on any registration form which does not
permit secondary sales, the Company will:

                 (i) promptly give to each Holder written notice thereof; and

                 (ii) use its best efforts to include in such registration (and
any related qualification under blue sky laws or other compliance), except as
set forth in Section 1.3(b) below, and in any underwriting involved therein, all
the Registrable Securities specified in a written request or requests, made by
any Holder within twenty (20) days after the written notice from the Company
described in clause (i) above is effective. Such written request may specify all
or part of a Holder's Registrable Securities.

             (b) UNDERWRITING. If the registration of which the Company gives
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 1.3(a)(i). In such event the right of any Holder to
registration pursuant to Section 1.3 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
(together with the Company and the holders of other securities of the Company
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the representative of the
underwriter or underwriters selected by the Company.

         Notwithstanding any other provision of this Section 1.3, if the
representative of the underwriters advises the Company in writing that marketing
factors require a limitation on the number of shares to be underwritten, the
representative may (subject to the limitations set forth below) exclude all
Registrable Securities from, or limit the number of Registrable Securities to be
included in, the registration and underwriting. The Company shall so advise all
Holders of securities requesting registration, and the number of shares of
securities that are entitled to be included in the registration and underwriting
shall be allocated as set forth in Section 1.15 or 1.16, as applicable. If any
Holder does not agree to the terms of any such underwriting, such Holder shall
be excluded therefrom by written notice from the Company or the underwriter. Any
Registrable Securities or other securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration.

         If shares are so withdrawn from the registration or if the number of
shares of Registrable Securities to be included in such registration was
previously reduced as a result of marketing factors, the Company shall then
offer to all persons who have retained the right to include


                                       9
<PAGE>

securities in the registration the right to include additional securities in the
registration in an aggregate amount equal to the number of shares so withdrawn,
with such shares to be allocated among the persons requesting additional
inclusion in accordance with Section 1.15 or 1.16, as applicable hereof.

         1.4 EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Section 1.2 hereof shall be borne by the Company, and reasonable fees and
expenses of one counsel for the selling shareholders shall also be borne by the
Company. All Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 1.3 hereof shall be borne by the
Company, and reasonable fees and expenses of one counsel for the selling
shareholders shall also be borne by the Company. Registration Expenses incurred
in connection with any registration, qualification or compliance pursuant to
Section 1.5 hereof and reasonable fees and expenses of one counsel for the
selling shareholders shall be borne by the Company. All Selling Expenses
relating to securities so registered shall be borne by the holders of such
securities pro rata on the basis of the number of shares of securities so
registered on their behalf.

         1.5 REGISTRATION ON FORM S-3.

             (a) After its initial public offering, the Company shall use its
best efforts to qualify for registration on Form S-3 or any comparable or
successor form or forms. After the Company has qualified for the use of Form
S-3, in addition to the rights contained in the foregoing provisions of this
Section 1, the Holders of Registrable Securities shall have the right to request
one registration on Form S-3 per annum (such requests shall be in writing and
shall state the number of shares of Registrable Securities to be disposed of and
the intended methods of disposition of such shares by such Holder or Holders),
provided, however, that the Company shall not be obligated to effect any such
registration if (i) the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) on Form S-3 at an
aggregate price to the public of less than $2,000,000, or (ii) in the event that
the Company shall furnish the certification described in paragraph 1.2(b) (but
subject to the limitations set forth therein) or (iii) in a given twelve-month
period, after the Company has effected two (2) such registration in any such
period.

             (b) If a request complying with the requirements of Section 1.5(a)
hereof is delivered to the Company, the provisions of Sections 1.2(a)(i) and
(ii) and Section 1.2(b) hereof shall apply to such registration. If the
registration is for an underwritten offering, the provisions of Sections 1.2(c)
and 1.2(d) hereof shall also apply to such registration.

         1.6 REGISTRATION PROCEDURES. In the case of each registration effected
by the Company pursuant to Section 1, the Company will keep each Holder advised
in writing as to the initiation of each registration and as to the completion
thereof. At its expense, the Company will use its best efforts to:

             (a) Keep such registration effective for a period of one hundred
twenty (120) days or until the Holder or Holders have completed the distribution
described in the registration statement relating thereto, whichever first
occurs; provided, however, that (i) such 120-day


                                       10
<PAGE>

period shall be extended for a period of time equal to the period the Holder
refrains from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company;
and (ii) in the case of any registration of Registrable Securities on Form S-3
which are intended to be offered on a continuous or delayed basis, such 120-day
period shall be extended, if necessary, to keep the registration statement
effective until all such Registrable Securities are sold, provided that Rule
415, or any successor rule under the Securities Act, permits an offering on a
continuous or delayed basis, and provided further that applicable rules under
the Securities Act governing the obligation to file a post-effective amendment
permit, in lieu of filing a post-effective amendment which (I) includes any
prospectus required by Section 10(a)(3) of the Securities Act or (II) reflects
facts or events representing a material or fundamental change in the information
set forth in the registration statement, the incorporation by reference of
information required to be included in (I) and (II) above to be contained in
periodic reports filed pursuant to Section 13 or 15(d) of the Exchange Act in
the registration statement;

             (b) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement;

             (c) Furnish such number of prospectuses and other documents
incident thereto, including any amendment of or supplement to the prospectus, as
a Holder from time to time may reasonably request;

             (d) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed;

             (e) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration;

             (f) Otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission, and make available to its security
holders, as soon as reasonably practicable, an earnings statement covering the
period of at least twelve months, but not more than eighteen months, beginning
with the first month after the effective date of the Registration Statement,
which earnings statement shall satisfy the provisions of Section 11(a) of the
Securities Act; and

             (g) In connection with any underwritten offering pursuant to a
registration statement filed pursuant to Section 1.2 hereof, the Company will
enter into an underwriting agreement reasonably necessary to effect the offer
and sale of Common Stock, provided such underwriting agreement contains
customary underwriting provisions and provided further that if the underwriter
so requests the underwriting agreement will contain customary contribution
provisions.

                                       11
<PAGE>

             (h) Furnish, at the request of any Holder, on the date that the
Common Stock is delivered to the underwriters for sale in connection with a
registration being sold through underwriters, (i) an opinion, if any, dated such
date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters and to the
Holders and (ii) a letter dated such date, from the independent certified public
accountants of the Company, in form and substance as is customarily given by
independent certified public accountants to underwriters in an underwritten
public offering, addressed to the underwriters, if any, and to the Holders
requesting registration of Registrable Securities.

         1.7 INDEMNIFICATION.

             (a) The Company will indemnify each Holder, each of its officers,
directors and partners, legal counsel and accountants and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which registration, qualification or compliance has been
effected pursuant to this Section 1, and each underwriter, if any, and each
person who controls within the meaning of Section 15 of the Securities Act any
underwriter, against all expenses, claims, losses, damages and liabilities (or
actions, proceedings or settlements in respect thereof) arising out of or based
on any untrue statement of a material fact contained in any prospectus, offering
circular or other document (including any related registration statement,
notification or the like) incident to any such registration, qualification or
compliance, or based on any omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or any violation by the Company of the Securities Act or any rule or regulation
thereunder, applicable to the Company and relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and will reimburse each such Holder, each of its officers,
directors, partners, legal counsel and accountants and each person controlling
such Holder, each such underwriter and each person who controls any such
underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating and defending or settling any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission based upon written
information furnished to the Company by such Holder (and regarding such Holder)
or underwriter and stated to be specifically for use therein. It is agreed that
the indemnity agreement contained in this Section 1.7(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Company (which consent
has not been unreasonably withheld).

             (b) Each Holder will, if Registrable Securities held by him are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its directors,
officers, partners, legal counsel and accountants and each underwriter, if any,
of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of
Section 15 of the Securities Act, each other such Holder and each of their
officers, directors and partners, and each person controlling such Holder,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement of a material fact
contained in any such registration statement, prospectus, offering circular or
other document, or any omission


                                       12
<PAGE>

to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, and will reimburse the Company and
such Holders, directors, officers, partners, legal counsel and accountants,
persons, underwriters or control persons for any legal or any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement or omission is made in such
registration statement, prospectus, offering circular or other document in
reliance upon and in conformity with written information regarding such Holder
furnished to the Company by such Holder specifically for inclusion therein;
provided, however, that the obligations of such Holder hereunder (i) shall not
apply to amounts paid in settlement of any such claims, losses, damages or
liabilities (or actions in respect thereof) if such settlement is effected
without the consent of such Holder (which consent shall not be unreasonably
withheld), and (ii) shall be limited in amount to the net proceeds received by
such Holder from the sale of shares pursuant to such registration, qualification
or compliance.

             (c) Any person entitled to indemnification hereunder (an
"Indemnified Party") will (i) give prompt written notice to the party required
to provide indemnification (an "Indemnifying Party") of any claim with respect
to which it seeks indemnification and (ii) permit such Indemnifying Party to
assume the defense of such claim with counsel reasonably satisfactory to the
Indemnified Party, provided, however, that any person entitled to
indemnification hereunder shall have the right to employ separate counsel and to
participate in the defense of such claim, but the fees and expenses of such
counsel shall be at the expense of such person unless (x) the Indemnifying Party
has agreed in writing to pay such fees or expenses, or (y) the Indemnifying
Party shall have failed to assume the defense of such claim and employ counsel
reasonably satisfactory to such person or (z) in the reasonable judgment of any
such person and the Indemnifying Party, based upon advice of their respective
counsel, a conflict of interest may exist between such person and the
Indemnifying Party with respect to such claims (in which case, if the person
notifies the Indemnifying Party in writing that such person elects to employ
separate counsel at the expense of the Indemnifying Party, the Indemnifying
Party shall not have the right to assume the defense of such claim on behalf of
such person). If such defense is not assumed by the Indemnifying Party, the
Indemnifying Party will not be subject to any liability for any settlement made
without its consent (but such consent will not be unreasonably withheld). No
Indemnifying Party shall consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to the Indemnified Party of a release from all
liability in respect to such claim or litigation without the consent of the
Indemnified Party. The failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 1.7 unless the Indemnifying Party is materially prejudiced
thereby. An Indemnifying Party who is not entitled to, or elects not to, assume
the defense of a claim will not be obligated to pay the fees and expenses of
more than one counsel for all parties indemnified by such Indemnifying Party
with respect to such claim, unless in the reasonable judgment of any Indemnified
Party a conflict of interest may exist between such Indemnified Party and any
other of such Indemnified Parties with respect to such claim, in which event the
Indemnifying Party shall be obligated to pay the fees and expenses of such
additional counsel or counsels. Each Indemnified Party shall furnish such
information regarding itself or the claim in question as an Indemnifying Party
may reasonably request in writing and as shall be reasonably required in
connection with the defense of such claim and litigation resulting therefrom.


                                       13
<PAGE>

             (d) If the indemnification provided for in this Section 1.7 is held
by a court of competent jurisdiction to be unavailable to an Indemnified Party
with respect to any loss, liability, claim, damage or expense referred to
therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified
Party hereunder, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such loss, liability, claim, damage or expense
in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in
connection with the statements or omissions which resulted in such loss,
liability, claim, damage or expense as well as any other relevant equitable
considerations, provided, however, that the amount of contribution by such
Indemnifying Party where such Indemnifying Party is a Holder shall be limited to
the net proceeds received by such Holder from the sale of shares pursuant to
such registration, qualification or compliance. The relative fault of the
Indemnifying Party and of the Indemnified Party shall be determined by reference
to, among other things, whether the untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

             (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

         1.8 INFORMATION BY HOLDER. Each Holder of Registrable Securities shall
furnish to the Company such information regarding such Holder and the
distribution proposed by such Holder as the Company may reasonably request and
as shall be reasonably required in connection with any registration,
qualification or compliance referred to in this Section 1.

         1.9 LIMITATIONS ON REGISTRATION OF ISSUES OF SECURITIES. From and after
the date of this Agreement, the Company shall not, without the prior written
consent of a majority in interest of the Holders, enter into any agreement with
any holder or prospective holder of any securities of the Company giving such
holder or prospective holder any registration rights the terms of which are not
subordinate to the rights of the Holders hereunder or which grant such holder or
prospective holder demand registration rights exercisable prior to those of the
Holders under Section 1.2 hereof.

         1.10 RULE 144 REPORTING. With a view to making available the benefits
of certain rules and regulations of the Commission which may permit the sale of
the Restricted Securities to the public without registration, the Company agrees
to use its best efforts to:

             (a) Make and keep public information available as those terms are
understood and defined in Rule 144 under the Securities Act, at all times from
and after ninety (90) days following the effective date of the first
registration under the Securities Act filed by the Company for an offering of
its securities to the general public; and

             (b) File with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Exchange Act at any time after it has become subject to such reporting
requirements.

         1.11 TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause
the Company to register Registrable Securities granted to a Holder by the
Company pursuant to this Section 1 may be transferred or assigned by a Holder to
(i) any transferee or assignee of not less than 200,000 shares of Registrable
Securities (as presently constituted and subject to subsequent adjustments for
stock splits, stock dividends, reverse stock splits and the like), (ii) any
constituent partner or member of a partnership or limited liability company
Holder, respectively, (iii) any direct or indirect subsidiary or parent of a
corporate Holder, (iv) any person, trust or other entity if beneficial ownership
or the power to vote or dispose of the Registrable Securities resides in the
same person after the transfer as immediately prior to such transfer or (v) any
Holder; provided, however, that the Company is given written notice at the time
of or within a reasonable time after such a transfer or assignment, stating the
name and address of said transferee or assignee and identifying the securities
with respect to which such registration rights are being transferred or
assigned, and provided further that the transferee or assignee of such rights
assumes in a written instrument provided to the Company the obligations of such
Holder under this Section 1. For purposes of clause (iv) of the foregoing
sentence, where two or more persons share beneficial ownership or power to vote
or dispose of Registrable Securities and such persons take as transferees a
distributive share equal to all or less than all of the Registrable Securities
to which they shared voting or dispositive power prior to the transfer, with
respect to each such person beneficial ownership or the power to vote or dispose
of the Registrable Securities held by them shall be deemed to reside in the same
person as prior to the transfer. In addition, subject to the approval of the
Board of Directors in its sole discretion, the right to cause the Company to
register Registrable Securities granted to a Holder pursuant to this Section 1
hereof may be assigned or transferred by a Holder to any other transferee who is
an affiliated person or entity of a Holder where such transfer is of the type
intended to be permitted by this Section 1.11. Any transferee or assignee under
the foregoing sentence must assume in a written instrument provided to the
Company the obligations of the transferring Holder under this Section 1.

         1.12 "MARKET STAND-OFF" AGREEMENT. If requested by the Company and an
underwriter of Common Stock (or other securities) of the Company, an Investor
shall not sell or otherwise transfer or dispose of any Common Stock (or other
securities) of the Company held by such Investor (other than those included in
the registration) during the one hundred eighty (180) day period following the
effective date of a registration statement of the Company filed under the
Securities Act, provided that all officers, directors and 5% shareholders of the
Company, who are not parties to this Agreement, enter into similar agreements.

         The obligations described in this Section 1.12 shall not apply to a
registration relating solely to employee benefit plans on Form S-1 or Form S-8
or similar forms which may be promulgated in the future, or a registration
relating solely to a Commission Rule 145 transaction on Form S-4 or similar
forms which may be promulgated in the future. The Company may impose
stop-transfer instructions with respect to the shares (or securities) subject to
the foregoing restriction until the end of said one hundred eighty (180) day
period.

         1.13 DELAY OF REGISTRATION. No Holder shall have any right to take any
action to restrain, enjoin, or otherwise delay any registration as the result of
any controversy that might arise with respect to the interpretation or
implementation of this Section 1.



                                       15

         1.14 TERMINATION OF REGISTRATION RIGHTS. The right of any Holder to
request registration or inclusion in any registration pursuant to this Agreement
shall terminate on the date on which all shares of Registrable Securities held
or entitled to be held upon conversion by such Holder may immediately be sold
under Rule 144 during any ninety (90) day period.

         1.15 EXCLUSION/ALLOCATION IN AN OFFERING BY THE COMPANY. With respect
to an underwritten public offering pursuant to Section 1.3 and related primarily
to an offering by the Company for its own account, if the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in the offering exceeds the amount of securities that the underwriters
determine in their sole discretion is compatible with the success of the
offering, then the Company shall be required to include in the offering only
that number of securities that the underwriters determine in their sole
discretion will not jeopardize the offering, in the following order of priority:
(i) first, securities to be offered by the Company for its own account and (ii)
second, Registrable Securities held by the Holders requesting inclusion of
Registrable Securities in the offering, based on their pro rata portion of all
Registrable Securities requested to be included in the offering. For purposes of
the preceding parenthetical concerning apportionment, for any selling
shareholder which is a Holder of Registrable Securities and which is a
partnership or corporation, the partners, retired partners and shareholders of
such holder, or the estates and family members of any such partners and retired
partners and any trusts for the benefit of any of the foregoing persons shall be
deemed to be a single "selling shareholder," and any pro-rata reduction with
respect to such "selling shareholder" shall be based upon the aggregate amount
of shares carrying registration rights owned by all entities and individuals
included in such "selling shareholder," as defined in this sentence.
Notwithstanding the foregoing, in no event shall the amount of securities of
selling holders included in such offering be reduced below twenty-five percent
(25%) of the total amount of securities included in such offering unless such
offering is the Company's initial public offering.

         1.16 EXCLUSION/ALLOCATION IN AN OFFERING BY HOLDERS. With respect to an
underwritten public offering (i) pursuant to Section 1.2 or 1.5 or (ii) pursuant
to Section 1.3 and related primarily to an offering by any person other than the
Company for its own account, if the total amount of securities requested to be
included in the offering exceeds the amount of securities that the underwriters
determine in their sole discretion is compatible with the success of the
offering, then there will be included in the offering only that number of
securities that the underwriters determine in their sole discretion will not
jeopardize the offering, in the following order of priority: (i) first,
Registrable Securities held by the Holders requesting inclusion of Registrable
Securities in the offering, based on their pro rata portion of all Registrable
Securities requested to be included in the offering; (ii) second, securities to
be offered by the Company for its own account; and (iii) third, any securities
held by a person who is not a Holder.

                                    SECTION 2

                            COVENANTS OF THE COMPANY

         2.1 DELIVERY OF FINANCIAL STATEMENTS. The Company shall deliver to each
Material Investor:

             (a) as soon as practicable, but in any event within ninety (90)
days after the end of each fiscal year of the Company, an income statement for
such fiscal year, a balance sheet of the Company and statement of shareholder's
equity as of the end of such year, and a statement of cash flows, such year-end
financial reports to be in reasonable detail, unaudited but prepared in
accordance with generally accepted accounting principles;

             (b) as soon as practicable, but in any event within forty-five (45)
days after the end of each of the first three (3) quarters of each fiscal year
of the Company, an unaudited profit or loss statement, statement of cash flows
for such fiscal quarter and an unaudited balance sheet as of the end of such
fiscal quarter;

             (c) annually as soon as practicable (but in any event at least
thirty (30) days prior to the commencement of each fiscal year of the Company)
the financial and operating plan of the Company, in such manner and form as
approved by the Board of Directors of the Company, which financial and operating
plan shall include a projection of income and a projected cash flow statement
for such fiscal year and a projected balance sheet as of the end of such fiscal
year.

         2.2 INSPECTION. The Company shall permit each Material Investor, at
such Material Investor's expense, to visit and inspect the Company's properties,
to examine its books of account and records and to discuss the Company's
affairs, finances and accounts with its officers, all at such reasonable times
as may be requested by the Material Investor; provided, however, that the
Company shall not be obligated pursuant to this Section 2.2 to provide access to
any information which it reasonably considers to be a trade secret or similar
confidential information.

         2.3 RIGHT OF FIRST REFUSAL. The Company hereby grants to each Material
Investor the right of first refusal to purchase a pro rata share of New
Securities (as defined in this Section 2.3) which the Company may, from time to
time, propose to sell and issue. For purposes of applying this Section 2.3, the
holdings of a Material Investor shall be deemed to include shares held by
entities who are controlled by or are under common control with the Material
Investor (a "Material Investor Affiliate"). A Material Investor's pro rata
share, for purposes of this right of first refusal, is the ratio of the number
of shares of Common Stock owned by such Material Investor, including shares
owned by such Material Investor's Affiliate(s), immediately prior to the
issuance of New Securities, assuming full conversion of the Preferred Shares and
the exercise of all Warrants, to the total number of shares of Common Stock
outstanding immediately prior to the issuance of New Securities, assuming full
conversion of the Preferred Shares and the exercise of all Warrants; provided,
however, that in the event two or more Material Investors have a common Material
Investor Affiliate, the shares owned by any Material Investor Affiliate may only
be counted once for purposes of determining pro rata ownership. Each Material
Investor shall have a right of over-allotment such that if any Material Investor
fails to exercise its right


                                       17
<PAGE>

hereunder to purchase its pro rata share of New Securities, the other
Material Investors may purchase the non-purchasing Material Investor's portion
on a pro rata basis within five (5) days from the date such non-purchasing
Material Investor fails to exercise its right hereunder to purchase its pro rata
share of New Securities. This right of first refusal shall be subject to the
following provisions:

             (a) "NEW SECURITIES" shall mean any capital stock (including Common
Stock and/or Preferred Stock) of the Company whether now authorized or not, and
rights, options or warrants to purchase such capital stock, and securities of
any type whatsoever that are, or may become, convertible into capital stock;
provided that the term "New Securities" does not include (i) the Preferred
Shares or the Warrants or securities issued upon conversion of the Preferred
Shares or the exercise of the Warrants; (ii) Securities issued upon conversion
of the AMT Convertible Note; (iii) any borrowings, direct or indirect, from
financial institutions or other persons by the Company, whether or not presently
authorized, including any type of loan or payment evidenced by any type of debt
instrument, including, without limitation, the debt instruments between the
Company and Silicon Valley Bank, provided such borrowings do not have any equity
features including warrants, options or other rights to purchase capital stock
and are not convertible into capital stock of the Company except for the
warrants to purchase stock from the Company in favor of Silicon Valley Bank with
respect to 48,000 shares of Series D Preferred Stock and 20,000 shares of Series
E Preferred Stock or securities issued upon exercise thereof; (iv) securities
issued to employees, consultants, officers or directors of the Company pursuant
to any stock option, stock purchase or stock bonus plan, agreement or other
compensation plan or arrangement approved by the Board of Directors; (iv)
securities issued in a firm commitment underwritten public offering pursuant to
a registration under the Securities Act provided that such public offering is a
Qualified IPO; (v) securities issued as consideration in connection with any
stock split, stock dividend or recapitalization of the Company; (vi) securities
issued in connection with a merger or acquisition transaction provided, that (1)
with respect to securities issued in connection with any such merger or
acquisition transaction, subject to subpart (2) below, upon completion of a such
merger the relative shareholdings of the Crossroads Parties (including options
and other rights to acquire an interest) in the surviving merged company shall
be in the same proportion to Wi-LAN's shareholdings in such merged company that
the Crossroads Parties' shareholdings (including options and other rights to
acquire an interest) were to Wi-LAN's shareholdings in the entity just prior to
the merger or acquisition, and (2) the interest of the Crossroads Parties may be
increased from that contemplated in subpart (1) above by virtue of the holding
of one or more of the Crossroads Parties, prior to the merger or acquisition, of
not more than 5% of the equity of the other party to the merger or acquisition
and provided, that in the aggregate of all such transactions and the Merger, the
relative proportionate interests of the Crossroads Parties to Wi-LAN in any
merged entity will not change by more than 20% of their proportionate interests
as of the Restructuring Date; (vii) Common Stock issued to a TRW, Inc. pursuant
to a License Agreement between the Company and TRW, Inc. dated as of January 14,
2000 and (viii) any right, option or warrant to acquire any security convertible
into the securities excluded from the definition of New Securities pursuant to
subsections (i) through (vi) above.

             (b) In the event the Company proposes to undertake an issuance of
New Securities, it shall give each Material Investor written notice of its
intention, describing the type of New Securities, and their price and the
general terms upon which the Company proposes to


                                       18
<PAGE>

issue the same. Each Material Investor shall have fifteen (15) days after any
such notice is effective to notify the Company of its desire to purchase such
Material Investor's pro rata share of such New Securities (a "Participating
Purchaser") for the price and upon the terms specified in the notice and such
Material Investor shall also state the quantity of New Securities to be
purchased (and include the proposed terms of financing for such participation if
such financing is required); provided, however, that the Material Investor shall
not be required to complete the purchase of its pro-rata share of New
Securities, if at all, until sixty (60) days after the effectiveness of
Company's original notice; provided further, that if, after a good faith effort,
the Material Investor is unable to raise the financing necessary to purchase its
pro-rata share of the New Securities, such notice shall not be binding on such
Material Investor. Upon the expiration of the sixty (60) day period specified in
the previous sentence, the Company shall give notice to each Participating
Purchaser, specifying the number of New Securities available for over-allotment
to Participating Purchasers (the "Over-allotment Securities"). Each
Participating Purchaser shall have five (5) business days after any such notice
is effective to agree to purchase such Participating Purchaser's pro rata share
of the Over-allotment Securities by giving written notice to the Company and
stating therein the number of Over-allotment Securities to be purchased.

             (c) In the event the Material Investors fail to exercise fully the
right of first refusal within said sixty (60) day period and after the
expiration of the five (5) business days allowed for the exercise of the
over-allotment provisions of this Section 2.3, the Company shall have ninety
(90) days thereafter to sell or enter into an agreement (pursuant to which the
sale of New Securities covered thereby shall be closed, if at all, within ninety
(90) days from the date of said agreement) to sell the New Securities respecting
which the Material Investors' right of first refusal option set forth in this
Section 2.3 was not exercised, at a price and upon terms no more favorable to
the purchasers thereof than specified in the Company's notice to Material
Investors pursuant to Section 2.3(b). In the event the Company has not sold
within said 90 day period or entered into an agreement to sell the New
Securities within said 90 day period (or sold and issued New Securities in
accordance with the foregoing within ninety (90) days from the date of said
agreement), the Company shall not thereafter issue or sell any New Securities,
without first again offering such securities to the Material Investors in the
manner provided in Section 2.3(b) above.

             (d) The right of first refusal granted under this Agreement shall
expire upon, and shall not be applicable to, the first sale of Common Stock of
the Company to the public effected pursuant to a registration statement filed
with, and declared effective by, the Commission under the Securities Act
provided that such sale is a Qualified IPO.

             (e) The right of first refusal set forth in this Section 2.3 may
not be assigned or transferred, except in a transfer permitted by Section 1.11.

         2.4 TERMINATION OF COVENANTS. The covenants set forth in this Sections
2.1 and 2.2 shall terminate and be of no further force and effect after the time
of effectiveness of the Company's first firm commitment underwritten public
offering registered under the Securities Act or when the Company first becomes
subject to the periodic reporting requirements of Sections 12(g) or 15(d) of the
Exchange Act, whichever event shall occur first.

                                    SECTION 3

                     RESTRICTIONS ON TRANSFER OF SECURITIES

         3.1 TRANSFER OF SECURITIES. Subject to the provisions of Section 3.2
hereof and subject to the rights granted to Wi-LAN pursuant to that certain
Third Amended and Restated Shareholders' Rights Agreement, dated as of June 3,
1998, (a) no Crossroads Investor may sell, assign, pledge or otherwise transfer
(a "Transfer") any interest in any Securities held by such Crossroads Investors
(the "Crossroads Securities"), either voluntarily or involuntarily, by operation
of law or otherwise, except (i) to such Crossroads Investor's Family Members,
provided that such Crossroads Investor retains voting control over the
transferred Crossroads Securities, (ii) to such Crossroads Investor's Personal
Representative, (iii) pursuant to a Third Party Sale subject to the provisions
of Sections 3.2 and 3.3 hereof or (iv) pursuant to a Public Sale; provided that,
in each case, (A) no Event of Default under (and as defined in) the Series E
Purchase Agreement would occur as a result of any such transfer, (B) the
restrictions contained in this Section 3 will continue to be applicable to any
transferee of Crossroads Securities by any Crossroads Investor pursuant to this
Section 3.1, and (C) the transferee of such Crossroads Securities pursuant to
clause (B) above shall have executed and delivered an Instrument of Accession as
a condition precedent to the transfer thereof.

         3.2 FIRST RIGHT OF PURCHASE. (a) Subject to the provisions of Section
3.1 hereof, any Crossroads Investor may Transfer any interest in any Crossroads
Securities pursuant to a Third Party Sale in accordance with the provisions of
this Section 3.2 and Section 3.3. At least 45 days prior to any Third Party
Sale, the transferring Crossroads Investor (the "Transferring Shareholder") will
deliver a written notice (the "Offer Notice") to the Company and to the Series E
Investor Shareholders (the "Non-Transferring Shareholders"). The Offer Notice
will disclose in reasonable detail the proposed number of shares of the
Crossroads Securities to be transferred, the class or classes of such Crossroads
Securities, the proposed price, terms and conditions of the Transfer and the
identity of the transferee. The Non-Transferring Shareholders may elect to
purchase all (but not less than all) of the Crossroads Securities specified in
the Offer Notice at the price and on the terms specified therein by delivering
written notice of such election to the Transferring Shareholder and the Company
within 30 days after the delivery of such Offer Notice (the "Shareholder
Election Period"). If the Non-Transferring Shareholders elect to purchase all of
such Crossroads Securities, the Transfer of the Crossroads Securities will be
consummated within 30 days after the expiration of the Shareholder Election
Period. If more than one Non-Transferring Shareholder elects to purchase all of
the Crossroads Securities to be transferred, each Non-Transferring Shareholder
electing to purchase such Crossroads Securities will be entitled to purchase
from the Transferring Shareholder a pro rata portion (based upon the respective
numbers of shares of Securities then held by such Non-Transferring Shareholders
(on a fully-diluted and converted basis)) of the Crossroads Securities proposed
to be transferred. If the Non-Transferring Shareholders do not elect to purchase
all of the Crossroads Securities being offered, the Transferring Shareholder
may, within 90 days after the expiration of the Shareholder Election Period,
complete the Third Party Sale of the Crossroads Securities specified in the
Offer Notice at a price and on terms no more favorable to the transferees than
the price and terms offered to the Non-Transferring Shareholders in the Offer
Notice, provided that no such Third Party Sale may be completed except in
compliance with Section 3.3 and unless each of such transferees shall have
executed and delivered an Instrument of Accession as a condition


                                       20
<PAGE>

precedent to the transfer thereof. If the Transferring Shareholder fails to
consummate such Third Party Sale within the 90 day period after the expiration
of the Shareholder Election Period, any subsequent proposed Transfer of the
Crossroads Securities shall be once again subject to the provisions of this
Section 3.2.

         3.3. PARTICIPATION RIGHTS. In the event that the Non-Transferring
Shareholders fail to purchase the Crossroads Securities specified in the Offer
Notice, any Series E Investor Shareholder may elect to participate in the
contemplated Third Party Sale by delivering written notice to the Transferring
Shareholder within 15 days after expiration of the Shareholder Election Period.
If a Series E Investor Shareholder elects to participate in such Third Party
Sale, each of the Transferring Shareholder and the Series E Investor
Shareholder(s) will be entitled to sell in the contemplated Third Party Sale, at
the same price and on the same terms, a number of shares of Securities proposed
to be sold equal to the product of (i) the fraction, the numerator of which is
the number of shares of Securities (on a fully-diluted basis) held by such
Person, and the denominator of which is the aggregate number of shares of
Securities (on a fully-diluted basis) owned by the Transferring Shareholder and
the Series E Investor Shareholder(s), MULTIPLIED BY (ii) the number of shares of
Securities (on a fully-diluted basis) to be sold in the contemplated Third Party
Sale.

         For example, if the notice from the Transferring Shareholder
         contemplated a sale of 100 shares of Securities by the Transferring
         Shareholder and the Transferring Shareholder at such time owns 300
         shares of Securities, and if a Series E Investor Shareholder elects to
         participate in such sale and the Series E Investor Shareholder owns 200
         shares of Securities (on a fully-diluted basis), such Transferring
         Shareholder would be entitled to sell 60 shares (300/500 x 100 shares)
         and the Series E Investor Shareholder would be entitled to sell 40
         shares (200/500 x 100 shares).

The Transferring Shareholder will use its best efforts to obtain the agreement
of the prospective  transferee(s)  to the  participation  of a Series E Investor
Shareholder  in any  contemplated  Third Party Sale and will not transfer any of
its Securities to the prospective transferee(s) if the prospective transferee(s)
declines to allow the  participation of the Series E Investor  Shareholder(s) on
the terms specified herein.

         3.4 TRANSFERS OF SECURITIES IN BREACH OF THIS AGREEMENT. In the event
of any Transfer of Existing Investor Securities in breach of this Section 3,
commencing immediately upon the date of such attempted Transfer (i) such
Transfer shall be void and of no effect, (ii) no dividend of any kind or any
distribution pursuant to any liquidation, redemption or otherwise shall be paid
by the Company to the purported transferee in respect of such Existing Investor
Securities (all such rights to payment by the transferring Shareholder and/or
the purported transferee being deemed waived), (iii) the voting rights of such
Existing Investor Securities, if any, shall terminate, and (iv) neither the
transferring Shareholder nor the purported transferee shall be entitled to
exercise any rights with respect to such Existing Investor Securities until such
Transfer in breach of this Agreement has been rescinded.

         3.5 TERMINATION. The provisions of this Section 3 shall terminate and
be of no further force and effect after the time of effectiveness of the
Company's Qualified IPO.

                               BOARD OF DIRECTORS

         4.1 BOARD OF DIRECTORS; VOTING AGREEMENTS. (a) Subject to adjustment as
provided below, in any and all elections of directors of the Company (whether at
a meeting or by written consent in lieu of a meeting), each of the undersigned
Holders, to the extent that such Holder has voting rights, shall vote, or cause
to be voted, or cause such Holder's designees as directors to vote, all
Securities, owned by such Holder or over which such Holder has voting control,
so as to fix the number of directors of such Company at nine (9), and to
nominate and elect four (4) directors of such Company as follows:

             (i) One (1) individual designated by GMN Investors II, L.P., so
long as GMN Investors II, L.P. or its Affiliates hold any Securities and
thereafter by the Majority Holders;

             (ii) One (1) individual designated by Stratford Equity Partners,
L.P., so long as Stratford Equity Partners, L.P. or its Affiliates hold any
Securities and thereafter by the Majority Holders;

             (iii) One (1) individual designated by DynaFund, L.P. and DynaFund
International, L.P. (together, the "DynaFund Entities") for so long as the
DynaFund Entities hold at least 200,000 Common Shares and thereafter by the
Majority Holders; and

             (iv) One (1) individual designated by TRW, Inc. for so long as TRW
and/or its Affiliates hold at least 2,500,000 Common Shares (subject to
appropriate adjustment in the event of any stock dividend, stock split,
combination or other similar recapitalization affecting such shares) or
securities of the Company which may be converted into at least 2,500,000 Common
Shares (subject to appropriate adjustment in the event of any stock dividend,
stock split, combination or other similar recapitalization affecting such
shares); provided, however, that it shall no longer be so entitled upon such
time as the holders of Common Shares and securities which may be converted into
or exercised for Common Shares on the date hereof no longer hold 51% of the
total Common Shares, assuming for all purposes that securities which may be
converted into or exercised for Common Shares are fully converted or exercised.

         If an Investor or the Majority Holders with designation rights as set
forth immediately above, as applicable, choose not to designate a director or
directors of the Company as provided above, the number of directors of such
Company shall be reduced accordingly until such time as such Investor or the
Majority Holders, as applicable, exercise their rights as provided above, at
which time the number of directors of such Company shall be increased
accordingly.

         (b) If any vacancy shall occur in the Board of Directors of the Company
as a result of death, disability, resignation or any other termination of a
director, the replacement for such vacating director shall be designated by the
Person or Persons who, pursuant to Section 4.1(a) above, originally designated
such vacating director. Each Person or Persons entitled to designate a director
or a replacement for a director pursuant to this Section 4 shall also be
entitled to designate the removal of such director with or without cause. Each
Holder agrees to vote, or to cause to be voted, all voting securities owned by
such Holder, or over which such Holder has voting control, in order to comply
with this Section 4.1.


                                       22

applicable, an irrevocable proxy, coupled with an interest, to vote all voting
Securities held by such Person to the extent necessary to carry out the
provisions of this Section 4 in the event of any breach by such Person of its
obligations under the voting agreement contained herein.

         4.3 TERMINATION. The provisions of this Section 4 shall terminate and
be of no further force and effect after the time of effectiveness of the
Company's Qualified IPO.

                                ADDITIONAL LEGEND

         So long as any New Investor Securities are subject to the provisions of
this Agreement, all certificates or instruments representing New Investor
Securities will have imprinted on them the following legend:

         terms of a certain Sixth Amended and Restated Investors' Rights
         Agreement, dated as of January 14, 2000, among the issuer of this

         restrictive provisions relating to the voting and transfer of shares of
         the stock represented hereby. A copy of such Agreement is on file at
         the Company's principal offices. Upon written request to the Company's
         Secretary, a copy of such Agreement will be provided without charge to

                                    SECTION 6

                             TRANSFEREE STOCKHOLDERS

                  The undersigned Holders will not Transfer any Securities to

                                    -------



               Right to Purchase            Shares of Common Stock
                               of Wireless, Inc.



     This Warrant and any shares acquired upon the exercise of this Warrant have

                                 Wireless, Inc.
                         Common Stock Purchase Warrant


     Wireless, Inc., a California corporation (together with any corporation
which shall succeed to or assume the obligations of Wireless, Inc. hereunder,
the "COMPANY"), hereby certifies that, for value received, __________ or its
assigns, is entitled, subject to the terms set forth below, to purchase from the
Company from time to time in accordance with Section 2.2 hereof, until the
termination in full or in part of this Warrant pursuant to Section 2.4 hereof,
up to _____ fully paid and non-assessable shares of Common Stock (as defined in
Section 12 hereof) at an initial purchase price per share of $.75 (such price
per share as adjusted from time to time as provided herein is referred to herein
as the "EXERCISE


<PAGE>


PRICE"). The number of shares of Common Stock for which this Warrant is
exercisable and the Exercise Price are subject to adjustment as provided herein.

     This Warrant is issued pursuant to the Securities Purchase Agreement (as
amended and in effect from time to time, the "SECURITIES PURCHASE AGREEMENT"),
dated as of September 30, 1999, among the Company, GMN Investors II, L.P. and
Stratford Equity Partners, L.P. and the other investors listed on Exhibit A
attached thereto, a copy of which is on file at the principal office of the
Company. The holder of this Warrant shall be entitled to all of the benefits
and shall be subject to all of the obligations of the Securities Purchase
Agreement.

1.   DEFINITIONS. Terms defined in the Securities Purchase Agreement and not
otherwise defined herein are used herein with the meanings so defined. Certain
terms are used in this Warrant as specifically defined in Section 12 hereof.

2.   EXERCISE OF WARRANT.

     2.1 EXERCISE. This Warrant may be exercised prior to its expiration
pursuant to Section 2.4 hereof by the holder hereof from time to time in
accordance with Section 2.2, by surrender of this Warrant, with the form of
subscription at the end hereof duly executed by such holder, to the Company at
its principal office, accompanied by payment, by certified or official bank
check payable to the order of the Company or by wire transfer to its account, in
the amount obtained by multiplying the number of shares of Common Stock for
which this Warrant is then being exercised by the Exercise Price then in effect.
In the event the Warrant is not exercised in full, the Company, at its expense,
will forthwith issue and deliver to or upon the order of the holder hereof a new
Warrant or Warrants of like tenor, in the name of the holder hereof or as such
holder (upon payment by such holder of any applicable transfer taxes) may
request, calling in the aggregate on the face or faces thereof for the number of
shares of Common Stock equal (without giving effect to any adjustment therein)
to the number of such shares called for on the face of this Warrant minus the
number of such shares (without giving effect to any adjustment therein) for
which this Warrant shall have been exercised. Upon any exercise of this Warrant,
in whole or in part, the holder hereof may pay the aggregate Exercise Price with
respect to the shares of Common Stock for which this Warrant is then being
exercised (collectively, the "EXERCISE SHARES") by surrendering its rights to a
number of Exercise Shares having a fair market value equal to or greater than
the required aggregate Exercise Price, in which case the holder hereof would
receive the number of Exercise Shares to which it would otherwise be entitled
upon such exercise, less the surrendered shares. For purposes of this Section
2.1, the fair market value of one share of Common Stock shall be equal to (i) in
the event such exercise is being made in connection with the occurrence of a
Capital Transaction, the Repurchase Price of such interest determined in
accordance with Section 13.5 of the Securities Purchase Agreement and (ii) in
all other cases, the Repurchase Price of such interest determined in accordance
with Section 13.4 of the Securities Purchase Agreement.

     2.2 WARRANT AGENT. In the event that a bank or trust company shall have
been appointed as trustee for the holder of the Warrant pursuant to Section 6.2
hereof, such bank or trust company shall have all the powers and duties of a
warrant agent appointed pursuant to Section 13

                                       2
<PAGE>


hereof and shall accept, in its own name for the account of the Company or such
successor entity as may be entitled thereto, all amounts otherwise payable to
the Company or such successor, as the case may be, on exercise of this Warrant
pursuant to this Section 2.

     2.3 TERMINATION. This Warrant shall terminate in full upon the earliest to
occur of (i) exercise in full, (ii) the fifth anniversary of the date on which
all shares of the Company's preferred stock owned or held by the Holder of this
Warrant have been redeemed or paid in full (including all accrued and unpaid
dividends thereon) or converted into Common Stock, and (iii) March 31, 2005.

3.   PUT OPTION; REGISTRATION RIGHTS. The holder of this Warrant has the option
to require the Company to purchase this Warrant and/or shares of Warrant Stock
at the times and in the manner specified in Section 13 of the Securities
Purchase Agreement. The holder of this Warrant has the right to cause the
Company to register this Warrant, and/or shares of Warrant Stock issued upon
exercise hereof, under the Securities Act and any blue sky or securities laws
of any jurisdictions within the United States at the time and in the manner
specified in the Investors Rights Agreement.

4.   DELIVERY OF STOCK CERTIFICATES ON EXERCISE.

     4.1 DELIVERY. As soon as practicable after the exercise of this Warrant in
full or in part, and in any event within ten (10) days thereafter, the Company,
at its expense (including the payment by it of any applicable issue taxes),
will cause to be issued in the name of and delivered to the holder hereof, or as
such holder (upon payment by such holder of any applicable transfer taxes) may
direct, a certificate or certificates for the number of fully paid and
non-assessable shares of Common Stock (or Other Securities) to which such holder
shall be entitled on such exercise, together with any other stock or other
securities and property (including cash, where applicable) to which such holder
is entitled upon such exercise.

     4.2 FRACTIONAL SHARES. In the event that the exercise of this Warrant, in
full or in part, results in the issuance of any fractional share of Common
Stock, then in such event the holder of this Warrant shall be entitled to cash
equal to the fair market value of such fractional share as determined in good
faith by the Company's Board of Directors.

5.   ADJUSTMENT FOR DIVIDENDS, DISTRIBUTIONS AND RECLASSIFICATIONS.
In case at any time or from time to time, the holders of Common Stock shall have
received, or (on or after the record date fixed for the determination of
shareholders eligible to receive) shall have become entitled to receive, without
payment therefor:

          (a)  other or additional stock, other securities, or property (other
     than cash) by way of dividend; or

          (b)  other or additional (or less) stock or other securities or
     property (including cash) by way of spin-off, split-up, reclassification,
     recapitalization, combination of shares or similar corporate restructuring;

                                       3
<PAGE>


OTHER THAN additional shares of Common Stock issued as a stock dividend or in a
stock-split (adjustments in respect of which are provided for in Section 7
hereof), then and in each such case the holder of this Warrant, on the exercise
hereof as provided in Section 2 hereof, shall be entitled to receive the amount
of stock and other securities and property (including cash in the case referred
to in subsection (b) of this Section 5) which such holder would have received
prior to or would have held on the date of such exercise if on the date hereof
it had been the holder of record of the number of shares of Common Stock called
for on the face of this Warrant and had thereafter, during the period from the
date hereof to and including the date of such exercise, retained such shares and
all such other or additional stock and other securities and property (including
cash in the case referred to in subsection (b) of this Section 5) receivable by
such holder as aforesaid during such period, without interest, giving effect to
all further adjustments called for during such period by Sections 6 and 7
hereof.

6.   ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.

     6.1 CERTAIN ADJUSTMENTS. In case at any time or from time to time, the
Company shall (i) effect a capital reorganization, reclassification or
recapitalization, (ii) consolidate with or merge into any other person, or (iii)
transfer all or substantially all of its properties or assets to any other
person under any plan or arrangement contemplating the dissolution of the
Company, then in each such case, the holder of this Warrant, on the exercise
hereof as provided in Section 2 hereof at any time after the consummation of
such reorganization, recapitalization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or effective date, the stock and other securities and property
(including cash) to which such holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
holder had so exercised this Warrant immediately prior thereto, all subject to
further adjustment thereafter as provided in Sections 5 and 7 hereof.

     6.2 APPOINTMENT OF TRUSTEE FOR WARRANT HOLDERS UPON DISSOLUTION. In the
event of any dissolution of the Company following the transfer of all or
substantially all of its properties or assets, the Company, prior to such
dissolution, shall, at its expense, deliver or cause to be delivered the stock
and other securities and property (including cash), where applicable) receivable
by the holders of the Warrant after the effective date of such dissolution
pursuant to this Section 6 to a bank or trust company having its principal
office in Boston, Massachusetts, as trustee for the holder or holders of the
Warrant.

     6.3 CONTINUATION OF TERMS. Upon any reorganization, consolidation, merger
or transfer (and any dissolution following any transfer) referred to in this
Section 6, this Warrant shall continue in full force and effect and the terms
hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person

                                       4
<PAGE>


acquiring all or substantially all of the properties or assets of the Company,
whether or not such person shall have expressly assumed the terms of this
Warrant as provided in Section 8 hereof.

7.   ADJUSTMENTS FOR ISSUANCE OF COMMON STOCK AND AMOUNT OF OUTSTANDING COMMON
     STOCK.

     7.1 GENERAL. If at any time there shall occur any stock split, stock
dividend, reverse stock split or other subdivision of the Company's Common Stock
("STOCK EVENT"), then the number of shares of Common Stock to be received by the
holder of this Warrant shall be appropriately adjusted such that the proportion
of the number of shares issuable hereunder to the total number of shares of the
Company (on a fully diluted basis) prior to such Stock Event is equal to the
proportion of the number of shares issuable hereunder to the total number of
shares of the Company (on a fully-diluted basis) after such Stock Event and the
Exercise Price shall be appropriately adjusted such that the aggregate Exercise
Price for the total number of shares of the Company issuable hereunder prior to
such Stock Event is equal to the aggregate Exercise Price for the total number
of shares of the Company issuable hereunder after such Stock Event; PROVIDED
that in no event will the Exercise Price be less than the par value of the
Common Stock.

     7.2 SALE OF COMMON STOCK. If at any time there shall occur any issuance or
sale by the Company of any shares of Common Stock or of any securities
convertible into or exchangeable for shares of Common Stock or any warrants,
options, subscriptions or purchase rights with respect to shares of Common Stock
or securities convertible into or exchangeable for shares of Common Stock (any
of the foregoing events being referred to herein as a "STOCK SALE EVENT" and the
securities issued in connection therewith being referred to herein as "NEW
SECURITIES"), so that (i) the total number of shares of Common Stock of the
Company on a fully-diluted basis immediately following such issuance or sale
exceeds the total number of shares of Common Stock on a fully-diluted basis
immediately following the issuance of the Warrants and (ii) the New Security
Price Per Share (as defined herein) of such newly issued securities is lower
than the then current Warrant Price Per Share (as defined herein), then the
number of shares of Common Stock to be received by the holder of this Warrant
under the unexercised portion of this Warrant shall be increased by multiplying
such number by the Factor (defined below), and the Exercise Price shall be
appropriately adjusted such that the aggregate Exercise Price for the total
number of shares of Common Stock of the Company issuable hereunder prior to such
Stock Sale Event is equal to the aggregate Exercise Price for the total number
of shares of Common Stock of the Company issuable hereunder after such Stock
Sale Event; provided, however, that the foregoing provisions shall not apply to
the issuance of any options or the issuance of any Common Stock upon exercise of
options issued pursuant to the Company's 1997 Stock Option/Stock Issuance Plan
or any shares of Common Stock issued pursuant to the Warrants. The Factor shall
be the quotient obtained by dividing one (1) by a fraction, the numerator of
which is the New Security Price Per Share and the denominator of which is the
Warrant Price Per Share. For purposes hereof, "WARRANT PRICE PER SHARE" shall
mean the "Conversion Price" as defined in the Certificate of Determination of
Preferences and Rights of Series E Preferred Stock of the Company (subject to
adjustment in the event of any stock splits, stock dividends, recapitalizations,
reorganizations and the like with respect to the Common Stock). For purposes
hereof, "NEW SECURITY PRICE PER SHARE"


                                       5
<PAGE>


shall mean (a) the sum of (I) the aggregate consideration paid by the purchasers
of the applicable New Securities for such New Securities plus (II) in the case
of any warrants, options, subscriptions or purchase rights with respect to
shares of Common Stock or securities convertible into or exchangeable for shares
of Common Stock, the minimum amount of consideration, if any, payable to the
Company upon exercise, conversion or exchange thereof (provided that, if the New
Securities are issued for no consideration, the consideration paid under this
clause (a) shall be deemed to be $.01 per share), divided by (b) the total
number of shares of Common Stock of the Company issued or sold to such
purchasers or to which such purchasers are entitled to convert the New
Securities.

     7.3 OTHER SECURITIES. In case any Other Securities shall have been issued,
or shall then be subject to issue upon the conversion or exchange of any stock
(or Other Securities) of the Company (or any other issuer of Other Securities or
any other entity referred to in Section 6 hereof) or to subscription, purchase
or other acquisition pursuant to any rights or options granted by the Company
(or such other issuer or entity), the holder hereof shall be entitled to receive
upon exercise hereof such amount of Other Securities (in lieu of or in addition
to Common Stock) as is determined in accordance with the terms hereof, treating
all references to Common Stock herein as references to Other Securities to the
extent applicable, and the computations, adjustments and readjustments provided
for in this Section 7 with respect to the number of shares of Common Stock
issuable upon exercise of this Warrant shall be made as nearly as possible in
the manner so provided and applied to determine the amount of Other Securities
from time to time receivable on the exercise of the Warrant, so as to provide
the holder of the Warrant with the benefits intended by this Section 7 and the
other provisions of this Warrant.

8. NO DILUTION OR IMPAIRMENT. The Company will not, by amendment of its Charter
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance of performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such action as may be necessary or appropriate in order
to protect the rights of the holder of the Warrant as described herein, in the
Securities Purchase Agreement or in any other Related Agreement, against
dilution. Without limiting the generality of the foregoing, the Company (i) will
not increase the par value of any shares of stock receivable on the exercise of
the Warrant above the amount payable therefor on such exercise, (ii) will take
all such action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and non-assessable shares of stock on the
exercise of the Warrant from time to time outstanding, (iii) will not issue any
capital stock of any class which is preferred as to dividends or as to the
distribution of assets upon voluntary or involuntary dissolution, liquidation or
winding up, unless the rights of the holders thereof shall be limited to a fixed
sum or percentage of par value in respect of participation in dividends and in
any such distribution of assets, (iv) will comply in all respects with the
provisions of Sections 6.1 through 6.18 and 7.1 through 7.11 of the Securities
Purchase Agreement except to the extent such compliance may be waived by Section
18 of the Securities Purchase Agreement, and (v) will not transfer all or
substantially all of its properties and assets to any other entity (corporate or
otherwise), or consolidate with or merge into any other entity or permit any
such entity to consolidate with or merge into the Company (if the Company is not
the surviving entity), unless

                                       6
<PAGE>


such other entity shall expressly assume in writing and will be bound by all the
terms of this Warrant and the Securities Purchase Agreement.

9.   ACCOUNTANTS' CERTIFICATE AS TO ADJUSTMENTS. In each case of any event that
may require any adjustment or readjustment in the shares of Common Stock
issuable on the exercise of this Warrant, the Company at its expense will
promptly prepare a certificate setting forth such adjustment or readjustment, or
stating the reasons why no adjustment or readjustment is being made, and
showing, in detail, the facts upon which any such adjustment or readjustment is
based, including a statement of (i) the number of shares of the Company's Common
Stock then outstanding on a fully diluted basis, and (ii) the number of shares
of Common Stock to be received upon exercise of this Warrant, in effect
immediately prior to such adjustment or readjustment and as adjusted and
readjusted (if required by Section 7) on account thereof. The Company will
forthwith mail a copy of each such certificate to the Majority Holders of the
Warrants, and will, on the written request at any time of the Majority Holders
of the Warrants, furnish to such holders a like certificate setting forth the
calculations used to determine such adjustment or readjustment. At its option,
the Majority Holders of the Warrants may confirm the adjustment noted on the
certificate by causing such adjustment to be computed by an independent
certified public accountant at the expense of the Company.

10.  NOTICES OF RECORD DATE. In the event of:

          (a) any taking by the Company of a record of the holders of any class
     of securities for the purpose of determining the holders thereof who are
     entitled to receive any dividend or other distribution, or any right to
     subscribe for, purchase or otherwise acquire any shares of stock of any
     class or any other securities or property, or to receive any other right;
     or

          (b) any capital reorganization of the Company, any reclassification or
     recapitalization of the capital stock of the Company or any transfer of all
     or substantially all the assets of the Company to or any consolidation or
     merger of the Company with or into any other Person; or

          (c) any voluntary or involuntary dissolution, liquidation or
     winding-up of the Company; or

          (d) any proposed issue or grant by the Company of any shares of stock
     of any class or any other securities, or any right or option to subscribe
     for, purchase or otherwise acquire any shares of stock of any class or any
     other securities (other than the issue of Common Stock on the exercise of
     this Warrant),

then, and in each such event, the Company will mail or cause to be mailed to the
Majority Holders of the Warrants a notice specifying (i) the date on which any
such record is to be taken for the purpose of such dividend, distribution or
right, and stating the amount and character of such dividend, distribution or
right, (ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or

                                       7
<PAGE>


winding-up is anticipated to take place, and the time, if any is to be fixed, as
of which the holders of record of Common Stock (or Other Securities) shall be
entitled to exchange their shares of Common Stock (or Other Securities) for
securities or other property deliverable on such reorganization,
reclassification, recapitalization, transfer, consolidation, merger,
dissolution, liquidation or winding-up and (iii) the amount and character of any
stock or other securities, or rights or options with respect thereto, proposed
to be issued or granted, the date of such proposed issue or grant and the
persons or class of persons to whom such proposed issue or grant is to be
offered or made. Such notice shall be mailed at least thirty (30) days prior to
the date specified in such notice on which any such action is to be taken.

11.  RESERVATION OF STOCK ISSUABLE ON EXERCISE OF WARRANT. The Company will at
all times reserve and keep available, solely for issuance and delivery on the
exercise of this Warrant, a number of shares of Common Stock equal to the total
number of shares of Common Stock from time to time issuable upon exercise of
this Warrant, and from time to time, will take all steps necessary to amend its
Charter to provide sufficient reserves of shares of Common Stock issuable upon
exercise of this Warrant.

12.  DEFINITIONS. As used herein the following terms, unless the context
otherwise requires, have the following respective meanings:

     12.1 The term COMMON STOCK includes (i) the Company's Common Stock, no par
value per share, (ii) any other capital stock of any class or classes (however
designated) of the Company, the holders of which shall have the right, without
limitation as to amount, either to all or to a share of the balance of current
dividends and liquidating dividends after the payment of dividends and
distributions on any shares entitled to preference, and (iii) any other
securities into which or for which any of the securities described in clauses
(i) or (ii) above have been converted or exchanged pursuant to a plan of
recapitalization, reorganization, merger, sale of assets or otherwise.

     12.2 The term OTHER SECURITIES refers to any stock (other than Common
Stock) and other securities of the Company or any other entity (corporate or
otherwise) (i) which the holder of this Warrant at any time shall be entitled to
receive, or shall have received, on the exercise of this Warrant, in lieu of or
in addition to Common Stock, or (ii) which at any time shall be issuable or
shall have been issued in exchange for or in replacement of Common Stock or
Other Securities, in each case pursuant to Section 5 or 6 hereof.

13.  WARRANT AGENT. The Company may, by written notice to the holder of this
Warrant, appoint an agent having an office in Boston, Massachusetts for the
purpose of issuing Common Stock on the exercise of this Warrant pursuant to
Section 2 hereof, and exchanging or replacing this Warrant pursuant to the
Securities Purchase Agreement, or any of the foregoing, and thereafter any such
issuance, exchange or replacement, as the case may be, shall be made at such
office by such agent.

14.  REMEDIES. The Company stipulates that the remedies at law of the holder of
this Warrant in the event of any default or threatened default by the Company in
the performance of

                                       8
<PAGE>


or compliance with any of the terms of this Warrant are not and will not be
adequate, and that such terms may be specifically enforced by a decree for the
specific performance of any agreement contained herein or by an injunction
against a violation of any of the terms hereof or otherwise.

15.  NOTICES. All notices and other communications from the Company to the
holder of this Warrant shall be mailed by first class registered or certified
mail, postage prepaid, or sent by overnight courier (or sent in the form of a
telex or telecopy) at such address as may have been furnished to the Company in
writing by such holder or, until any such holder furnishes to the Company an
address, then to, and at the adress of, the last holder of this Warrant who has
so furnished an address to the Company.

16.  MISCELLANEOUS. In case any provision of this Warrant shall be invalid,
illegal or unenforceable, or partially invalid, illegal or unenforceable, the
provision shall be enforced to the extent, if any, that it may legally be
enforced and the validity, legality and enforceabilty of the remaining
provisions shall not in any way be affected or impaired thereby. This Warrant
and any term hereof may be changed, waived, discharged or terminated only by a
statement in writing signed by the party against which enforcement of such
change, waiver, discharge or termination is sought. This Warrant shall be
governed by and construed in accordance with the domestic substantive laws (and
not the conflict of law rules) of the Commonwealth of Massachusetts. The
headings in this Warrant are for purposes of reference only, and shall not
limit or otherwise affect any of the terms hereof. This Warrant shall take
effect as an instrument under seal.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

                            WARRANT TO PURCHASE STOCK

Corporation:                 Multipoint Networks Inc., a California corporation
Number of Shares:            2,500,000
Class of Stock:              Common Stock
Initial Exercise Price:      $0.01 per share
Issue Date:                  May 5, 1997
Expiration Date:             May 5, 2002 (subject to Article 4.1)

     THIS WARRANT CERTIFIES THAT, in consideration of the payment of $1.00 and
for other good and valuable consideration, IMPERIAL BANCORP as of parent
IMPERIAL BANK or IMPERIAL BANK at Holder's election, ("Holder") is entitled to
purchase the number of fully paid and nonassessable shares of the class of
securities (the "Shares") of the corporation (the "Company") at the initial
exercise price per Share (the "Warrant Price") all as set forth above and as
adjusted pursuant to Article 2 of this Warrant subject to the provisions and
upon the terms and conditions set forth of this Warrant.

ARTICLE 1. EXERCISE

     1.1 METHOD OF EXERCISE. Holder may exercise this Warrant by delivering this
Warrant and a duly executed Notice of Exercise in substantially the form
attached as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

     1.2 CONVERSION RIGHT. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.4.

     1.3 RIGHT TO PUT WARRANT. At Holder's option, in lieu of exercising its
rights as set forth in Sections 1.1, or 1.2, Holder shall have the right to
require the Company to purchase the Warrant under the circumstances set forth on
Exhibit A.



                                  Page 1 of 10
<PAGE>


     1.4 FAIR MARKET VALUE. If the Shares are traded regularly in a public
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not regularly traded in
a public market, the Board of Directors of the Company shall determine fair
market value in its reasonable good faith judgment.

     1.5 DELIVERY OF CERTIFICATE AND NEW WARRANT. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.6 REPLACEMENT OF WARRANTS. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and amount to the Company or, in the
case of mutilation, or surrender and cancellation of this Warrant, the Company
at its expense shall execute and deliver, in lieu of this Warrant, a new warrant
of like tenor.

     1.7 REPURCHASE ON SALE, MERGER, OR CONSOLIDATION OF THE COMPANY.

          1.7.1. "ACQUISITION". For the purpose of this Warrant, "Acquisition"
means any sale, license, or other disposition of all or substantially all of the
assets (including intellectual property) of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

          1.7.2. ASSUMPTION OF WARRANT. If upon the closing of any Acquisition
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly. The Company shall use reasonable efforts to cause the surviving
corporation to assume the obligations of this Warrant.

         1.7.3. NONASSUMPTION. If upon the closing of any Acquisition the
successor entity does not assume the obligations of his Warrant and Holder has
not otherwise exercised his Warrant in full, then the unexercised portion of
this Warrant shall be deemed to have been automatically converted pursuant to
Section 1.2 and thereafter Holder shall participate in the acquisition on the
same terms as other holders of the same class of securities of the Company.

          1.7.4. PURCHASE RIGHT. Notwithstanding the foregoing, at the election
of Holder, the Company shall purchase the unexercised portion of this Warrant
for cash upon the closing of any Acquisition for an amount equal to (a) the fair
market value of any consideration that would have been received by Holder in
consideration of the Shares had Holder exercised the unexercised portion of this
Warrant immediately before the record date for determining the shareholders
entitled to participate in the

                                  Page 2 of 10
<PAGE>


proceeds of the Acquisition, less (b) the aggregate Warrant Price of the Shares,
but in no event less than zero.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

         2.1 STOCK DIVIDENDS, SPLITS, ETC. If the Company declares or pays a
dividend on its common stock payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
then upon exercise of this Warrant, for each Share acquired, Holder shall
receive, without cost to Holder, the total number and kind of securities to
which Holder would have been entitled had Holder owned the Shares of record as
of the date the dividend or subdivision occurred.

     2.2 RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock pursuant to the terms of the Company's Articles of Incorporation upon the
closing of a registered public offering of the Company's common stock. The
Company or its successor shall promptly issue to Holder a new Warrant for such
new securities or other property. The new Warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property issuable upon exercise
of the new Warrant. The provisions of this Section 2.2 shall similarly apply to
successive reclassifications, exchanges, substitutions, or other events.

     2.3 ADJUSTMENTS FOR COMBINATIONS, ETC. If the outstanding Shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

     2.4 NO IMPAIRMENT. The Company shall not, by amendment of its Articles of
Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out all the provisions of this Article 2 and in
taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

     2.5 CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief

                                  Page 3 of 10
<PAGE>


Financial Officer setting forth such adjustment and the facts upon which such
adjustment is based. The Company shall, upon written request, furnish Holder a
certificate setting forth the Warrant Price in effect upon the date thereof and
the series of adjustments leading to such Warrant Price.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

     3.1 REPRESENTATIONS AND WARRANTIES. The Company hereby represents and
warrants to the Holder as follows:

          (a) The initial Warrant Price referenced on the first page of this
Warrant is not greater than the fair market value of the Shares as of the date
of this Warrant.

     (b) All Shares which may be issued upon the exercise of the purchase right
represented by this Warrant, and all securities, if any, issuable upon
conversion of the Shares, shall, upon issuance, be duly authorized, validly
issued, fully paid and nonassessable, and free of any liens and encumbrances
except for restrictions on transfer provided for herein or under applicable
federal and state securities laws.

     3.2 NOTICE OF CERTAIN EVENTS. If the Company proposes at any time (a) to
declare any dividend or distribution upon its common stock, whether in cash,
property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for subscription pro rata to the holders of any class or series of
its stock any additional shares of stock of any class or series or other rights;
(c) to effect any reclassification or recapitalization of common stock; (d) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (e) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give
Holder (1) at least 10 days prior written notice of the date on which a record
will be taken for such dividend, distribution, or subscription rights (and
specifying the date on which the holders of common stock will be entitled
thereto) or for determining rights to vote, if any, in respect of the
matters referred to in (c) and (d) above; (2) in the case of the matters
referred to in (c) and (d) above at least 10 days prior written notice of the
date when the same will take place (and specifying the date on which the holders
of common stock will be entitled to exchange their common stock for securities
or other property deliverable upon the occurrence of such event); and (3) in the

                           CONVERTIBLE PROMISSORY NOTE

$1,000,000.00                                                   August 17, 1999

of that certain Note Purchase Agreement dated as of August 17, 1999 by and
between the Company and Payee (the "Purchase Agreement"). This Note shall be

Company agrees that this Note is entitled to all of the benefits provided in the
Purchase Agreement including, without limitation, all representations,
warranties and covenants of the Company contained therein and all remedies
provided therein. Reference herein to the Purchase Agreement shall not affect or
impair the absolute and unconditional obligation of the Company to pay this Note
when due. Capitalized terms that are not defined herein shall have such meanings
as are assigned to them in the Purchase Agreement.

         The unpaid principal balance of this Note shall bear interest at a rate
equal to seventeen percent (17%) per annum. Accrued interest shall be calculated
on the basis of a 365-day year. Interest accrued hereon shall be due and payable
on the first day of each December, March, June and September, beginning December
1, 1999, until the entire unpaid principal amount of this Note is repaid to
Payee.

         Notwithstanding anything in this Note to the contrary, in the event the
Company obtains, no later than fourteen (14) days following the date hereof, the
final, full, irrevocable and unconditional waiver of all preemptive rights,
rights of first refusal, and similar rights regarding the issuance by the
Company to Payee of this Note and any and all capital stock upon the conversion
of this Note as provided herein (the "Waivers"), then thereafter (i) this Note
shall mature on September 1, 2004 instead of on September 1, 2000, and (ii) the
unpaid principal balance of this Note shall bear interest at a rate equal to ten
percent (10%) per annum.

the maximum rate allowed by applicable law.
<PAGE>

bank account that Payee shall designate to the Company in writing.

Purchase Agreement, Payee shall have the option of declaring the principal
balance hereof and the interest accrued hereon to be immediately due and

         (a)  CONVERSION PROCEDURES.

                  (i) CONVERSION RIGHT. Subject to and upon compliance with the
         terms hereof, at any time after the date hereof, the holder of this
         Note may elect, by giving written notice of such election to the
         Company, to convert all or any portion of the principal amount of and
         interest on this Note into shares of fully paid and non-assessable
         shares of the class of the Company's preferred stock purchased by the
         investor(s) in the Company's arms' length equity financing, if any,
         most immediately following the date hereof (such financing being the
         "Next Financing" and such class of preferred stock being the "Preferred
         Stock"), which number of shares shall be determined by dividing such
         amount by the "Preferred Stock Conversion Price" (as determined below)
         in effect at the time of conversion. The conversion price payable for
         each share of Preferred Stock into which this Note is convertible
         shall, subject to further adjustment as provided herein, be equal to
         the lesser of (i) 125% of the per-share purchase price paid for the
         Preferred Stock in the Next Financing, or (ii) $3.75 (as applicable,
         such per share price, as adjusted, the "Preferred Stock Conversion
         Price").

                  In the event (a) an Organic Change (as defined below) occurs
         prior to the Next Financing, or (b) the Next Financing does not occur
         prior to October 31, 1999, then in either event and subject to and upon
         compliance with the terms hereof the holder of this Note may elect (at
         any time after receiving notice of the Organic Change in accordance
         with the terms hereof or at any time after October 31, 1999 if the Next
         Financing has not then occurred), by giving written notice of such
         election to the Company, to convert all or any portion of the principal
         amount of and interest on this Note into shares of fully paid and
         non-assessable shares of the Company's common stock (the "Common
         Stock"), which number of shares shall be determined by dividing such
         amount by the "Common Stock Conversion Price" (as determined below) in
         effect at the time of conversion. The conversion price payable for each
         share of Common Stock into which this Note is convertible shall,
         subject to further adjustment as provided herein, be equal to $1.25 (as
         adjusted, the "Common Stock Conversion Price," and unless otherwise
         specifically


                                       2
<PAGE>


         referenced, the Preferred Stock Conversion Price and the Common Stock
         Conversion Price are collectively referred to herein as the "Conversion
         Price").

                  If only a portion of this Note is converted to capital stock,
         the Company shall return this Note to the Holder with a notation of the
         remaining outstanding principal of this Note or, at the request of the
         Holder of this Note, shall issue and deliver to such Holder, a
         replacement convertible promissory note for the remaining outstanding
         balance hereof.

                  (ii) PREPAYMENT/CONVERSION RIGHT. In the event the Company
         notifies the Payee that the Company has elected to exercise its right
         to prepay this Note as set forth above, the Payee may elect to convert
         this Note into shares of capital stock pursuant hereto at any time
         prior to the actual tender of such payment by the Company in accordance
         with the terms hereof, and the conversion right granted to Payee
         pursuant hereto shall only terminate upon the actual tender for payment
         by the Company of the prepayment price of this Note to Payee in
         accordance with the terms hereof. In the event Payee elects to convert
         all or a portion of this Note after the Company elects to prepay this
         Note, but before payment of this Note is tendered in accordance with
         the terms hereof, the Company's prepayment right with respect to the
         amount designated to be converted shall terminate immediately upon
         Payee's notice of its election to convert, and the Note (or appropriate
         portion thereof) shall be converted into shares of capital stock in
         accordance with the terms hereof.

                  (iii) DELIVERY OF CERTIFICATES. As soon as possible after
         conversion has been effected (but in any event within five business
         days), the Company will deliver to the converting holder a certificate
         or certificates representing the number of shares of capital stock
         issuable by reason of such conversion registered in such name or names
         and such denomination or denominations as the converting holder has
         specified.

                  (iv) FURTHER ASSURANCES. The issuance of certificates for
         shares of capital stock upon conversion of this Note will be made
         without charge to the holder of this Note for any issuance tax in
         respect thereof or other cost incurred by the Company in connection
         with such conversion and the related issuance of shares of stock. Upon
         conversion of this Note, the Company will take all such actions as are
         necessary in order to ensure that the shares issuable with respect to
         such conversion will be validly issued, fully paid and nonassessable.

                  (v) BOOKS TO BE KEPT OPEN. The Company will not close its
         books against the transfer of this Note or of capital stock issued or
         issuable upon conversion of this Note in any manner which interferes
         with the timely conversion of this Note.

                  (vi) FRACTIONAL SHARES. If any fractional interest in a share
         would be deliverable upon any conversion of this Note, the Company, in
         lieu of delivering the fractional share therefor, will, pay an amount
         to the holder thereof equal to such fractional interest multiplied by
         the applicable Conversion Price as of the date of conversion.

          (b) ADJUSTMENTS TO CONVERSION PRICE AND NUMBER OF SHARES. The
     Conversion Price and the number of shares into which this
     Note is convertible shall be subject to adjustment as follows:

                  (i)  ISSUANCE OF ADDITIONAL SHARES.

                           (A) If the Company issues or sells shares of
                  Preferred Stock, or in any manner grants any warrants, options
                  or other rights (collectively, "Preferred Options") to
                  purchase shares of Preferred Stock or any other securities
                  convertible into or exchangeable for Preferred Stock
                  ("Preferred Convertible Securities"), which entitles the
                  subscriber, or the holder of such Preferred Option or
                  Preferred Convertible Security, to purchase any share of
                  Preferred Stock at less than the then current Preferred Stock
                  Conversion Price (if then applicable), then the Preferred
                  Stock Conversion Price in effect immediately prior to such
                  action by the Company shall be adjusted by being multiplied by
                  the fraction obtained:

                           by dividing

                           (X), which is the numerator obtained by adding (A)
                           the total number of issued and outstanding shares of
                           Preferred Stock immediately prior to the
                           effectiveness of such action by the Company, plus (B)
                           the number of shares of Preferred Stock that could
                           have been acquired, at the Preferred Stock Conversion
                           Price in effect immediately prior thereto, with the
                           consideration, if any, received or deemed received by
                           the Company in exchange for such action,

                           by

                           (Y), which is the denominator that equals the sum of
                           the actual total number of issued and outstanding
                           shares, plus the number of shares in a Preferred
                           Deemed Issue (defined below), of Preferred Stock
                           immediately after such effectiveness.

                           In case at any time the Company shall grant or issue
                  any Preferred Options or Preferred Convertible Securities,
                  whether or not such Preferred Options or the rights to convert
                  or exchange any such Preferred Convertible Securities are
                  immediately exercisable, and the price per share for which
                  Preferred Stock is issuable upon the exercise of such
                  Preferred Options or upon the conversion or exchange of such
                  Preferred Convertible Securities (determined by dividing (x)
                  the total amount, if any, received or receivable by the
                  Company as consideration for the issue or grant of such
                  Preferred Options and Preferred Convertible Securities, plus
                  the minimum aggregate amount of additional consideration
                  payable to the Company upon the exercise of such Preferred
                  Options and the conversion or exchange of such Preferred
                  Convertible Securities, including, in the case of any such
                  Preferred Options which relate to Preferred Convertible
                  Securities, the minimum aggregate amount of additional
                  consideration, if any, payable to the Company upon the
                  conversion or exchange of such Preferred Convertible

                  Securities, by (y) the total maximum number of shares
                  of Preferred Stock issuable upon the exercise of such
                  Preferred Options and upon the conversion or exchange of all
                  such Preferred Convertible Securities) shall be less than the
                  Preferred Stock Conversion Price in effect immediately prior
                  to the time of the granting of such Preferred Options or
                  Preferred Convertible Securities, then the total maximum
                  number of shares of Preferred Stock issuable upon the exercise
                  of such Preferred Options and upon the conversion or exchange
                  of the total maximum amount of such Preferred Convertible
                  Securities (including those issuable upon the exercise of
                  Preferred Options) shall, as of the date of granting of such
                  Preferred Options and Preferred Convertible Securities, be
                  deemed to be outstanding and to have been issued and sold for
                  such price per share (a "Preferred Deemed Issue") and the
                  provisions of this paragraph (i) shall apply accordingly.

                           (B) If the Company issues or sells shares of Common
                  Stock, or in any manner grants any warrants, options or other
                  rights (collectively, "Common Options") to purchase shares of
                  Common Stock or any other securities convertible into or
                  exchangeable for Common Stock ("Common Convertible
                  Securities"), which entitles the subscriber, or the holder of
                  such Common Option or Common Convertible Security, to purchase
                  any share of Common Stock at less than the then current Common
                  Stock Conversion Price (if then applicable), then the Common
                  Stock Conversion Price in effect immediately prior to such
                  action by the Company shall be adjusted by being multiplied by
                  the fraction obtained:

                           by dividing

                           (X), which is the numerator obtained by adding (A)
                           the total number of issued and outstanding shares of
                           Common Stock immediately prior to the effectiveness
                           of such action by the Company, plus (B) the number of
                           shares of Common Stock that could have been acquired,
                           at the Common Stock Conversion Price in effect
                           immediately prior thereto, with the consideration, if
                           any, received or deemed received by the Company in
                           exchange for such action,

                           by

                           (Y), which is the denominator that equals the sum of
                           the actual total number of issued and outstanding
                           shares, plus the number of shares in a Common Deemed
                           Issue (defined below), of Common Stock immediately
                           after such effectiveness.

                           In case at any time the Company shall grant or issue
                  any Common Options or Common Convertible Securities, whether
                  or not such Common Options or the rights to convert or
                  exchange any such Common Convertible Securities are
                  immediately exercisable, and the price per share for which
                  Common Stock is issuable upon the exercise of such Common
                  Options or upon the conversion or exchange of such Common
                  Convertible Securities (determined by dividing (x) the


                                       5
<PAGE>


                  total amount, if any, received or receivable by the
                  Company as consideration for the issue or grant of such Common
                  Options and Common Convertible Securities, plus the minimum
                  aggregate amount of additional consideration payable to the
                  Company upon the exercise of such Common Options and the
                  conversion or exchange of such Common Convertible Securities,
                  including, in the case of any such Common Options which relate
                  to Common Convertible Securities, the minimum aggregate amount
                  of additional consideration, if any, payable to the Company
                  upon the conversion or exchange of such Common Convertible
                  Securities, by (y) the total maximum number of shares of
                  Common Stock issuable upon the exercise of such Common Options
                  and upon the conversion or exchange of all such Common
                  Convertible Securities) shall be less than the Common Stock
                  Conversion Price in effect immediately prior to the time of
                  the granting of such Common Options or Common Convertible
                  Securities, then the total maximum number of shares of Common
                  Stock issuable upon the exercise of such Common Options and
                  upon the conversion or exchange of the total maximum amount of
                  such Common Convertible Securities (including those issuable
                  upon the exercise of Common Options) shall, as of the date of
                  granting of such Common Options and Common Convertible
                  Securities, be deemed to be outstanding and to have been
                  issued and sold for such price per share (a "Common Deemed
                  Issue") and the provisions of this paragraph (i) shall apply
                  accordingly.

                           Notwithstanding anything in this Note to the
                  contrary, this paragraph (b)(i)(B) shall not be applicable to
                  any of the following:

                           (1)      shares of Common Stock issued upon
                                    conversion of any of the Company's
                                    preferred stock;

                           (2)      shares of Common Stock issued to officers,
                                    directors, employees and consultants or
                                    other service providers of the Company
                                    pursuant to a stock grant, stock option plan
                                    or purchase plan or other employee stock
                                    incentive program or agreement approved by
                                    the Company's Board of Directors;

                           (3)      shares of capital stock issued or issuable
                                    in connection with a bona fide equipment
                                    lease or bank financing transaction approved
                                    by the Company's Board of Directors,
                                    including without limitation shares issued
                                    upon the exercise of warrants issued in
                                    connection with such transactions; or

                           (4)      shares of capital stock issued or issuable
                                    in connection with a merger or acquisition
                                    transaction.

                  (ii) TREATMENT OF EXPIRED OPTIONS AND UNEXERCISED CONVERTIBLE
         SECURITIES. Upon the expiration of any Preferred Option or Common
         Option or the termination of any right to convert or exchange any
         Preferred Convertible Security or Common Convertible Security without
         the exercise or conversion of any such option, convertible security or


                                       6
<PAGE>


         right, the Preferred Conversion Price or Common Conversion Price then
         in effect and the number of shares into which this Note is then
         convertible will be adjusted to the Preferred Conversion Price or
         Common Conversion Price, as applicable, and number of shares which
         would have been in effect at the time of such expiration or termination
         had such option or convertible security, to the extent outstanding
         immediately prior to such expiration or termination, never been issued.

                  (iii) TREASURY SHARES. The number of shares of capital stock
         outstanding at any given time does not include shares owned or held by
         or for the account of the Company, and the disposition of any shares so
         owned or held will be considered an issue or sale of capital stock.

                  (iv) RECORD DATE. If the Company takes a record of the holders
         of capital stock for the purpose of entitling them (A) to receive a
         dividend or other distribution payable in capital stock, options or in
         convertible securities or (B)to subscribe for or purchase capital
         stock, options or convertible securities, then such record date will be
         deemed to be the date of the issue or sale of the shares of capital
         stock deemed to have been issued or sold upon the declaration of such
         dividend or upon the making of such other distribution or the date of
         the granting of such right of subscription or purchase, as the case may
         be.

                  (v)  SUBDIVISION OR COMBINATION OF CAPITAL STOCK.

                           If the Company at any time after the date hereof
                  subdivides (by any stock split, stock dividend,
                  recapitalization or otherwise) its outstanding shares of
                  Preferred Stock into a greater number of shares, the Preferred
                  Stock Conversion Price in effect immediately prior to such
                  subdivision will be proportionately reduced and the number of
                  shares of Preferred Stock into which this Note is then
                  convertible shall be proportionately increased, and if the
                  Company at any time combines (by reverse stock split or
                  otherwise) its outstanding shares of Preferred Stock into a
                  smaller number of shares, the Preferred Stock Conversion Price
                  in effect immediately prior to such combination will be
                  proportionately increased and the number of shares of
                  Preferred Stock into which this Note is then convertible shall
                  be proportionately decreased.

                           If the Company at any time after the date hereof
                  subdivides (by any stock split, stock dividend,
                  recapitalization or otherwise) its outstanding shares of
                  Common Stock into a greater number of shares, the Common Stock
                  Conversion Price in effect immediately prior to such
                  subdivision will be proportionately reduced and the number of
                  shares of Common Stock into which this Note is then
                  convertible shall be proportionately increased, and if the
                  Company at any time combines (by reverse stock split or
                  otherwise) its outstanding shares of Common Stock into a
                  smaller number of shares, the Common Stock Conversion Price in
                  effect immediately prior to such combination will be
                  proportionately increased and the number of shares of Common
                  Stock into which this Note is then convertible shall be
                  proportionately decreased.

                  (vi) REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER
         OR SALE. Any capital reorganization, reclassification, consolidation,
         merger or sale of all or substantially all of the Company's assets to
         another person which is effected in such a way that holders of capital
         stock are entitled to receive (either directly or upon subsequent
         liquidation) stock, securities or assets with respect to or in exchange
         for capital stock is referred to herein as an "Organic Change." Prior
         to the consummation of any Organic Change, the Company will make
         appropriate provisions (in form and substance satisfactory to the
         holder of this Note) to ensure that such holder will thereafter have
         the right to acquire and receive, in lieu of or in addition to the
         shares of capital stock that immediately prior thereto are acquirable
         and receivable upon the conversion of this Note, such shares of stock,
         securities or assets as such holder would have received in connection
         with such Organic Change if such holder had fully converted this Note
         immediately prior to such Organic Change. The Company will not effect
         any such consolidation, merger or sale, unless prior to the
         consummation thereof, the successor (if other than the Company)
         resulting from consolidation or merger or the party purchasing such
         assets assumes by written instrument (in form reasonably satisfactory
         to the holder hereof), the obligation to deliver to such holder such
         shares of stock, securities or assets as, in accordance with the
         foregoing provisions, such holder may be entitled to acquire.

                  (vii) CERTAIN EVENTS. If any event occurs of the type
         contemplated by the provisions of this section (b) but not expressly
         provided for by such provisions, then the Company's Board of Directors
         will make an appropriate adjustment in the Preferred Stock Conversion
         Price or Common Stock Conversion Price, as applicable, and the number
         of shares for which this Note is convertible so as to protect the
         rights of the holder hereof; provided, that no such adjustment will
         increase such conversion price as otherwise determined pursuant hereto
         or decrease the number of shares of capital stock issuable upon
         conversion hereof.

                  (viii)  NOTICES.

                           (A) Immediately upon any adjustment of the Conversion
         Price or the number of shares for which this Note is convertible, the
         Company will give written notice thereof to the holder hereof.

                           (B) The Company will give written notice to the
         holder hereof at least 10 days prior to the date on which the Company
         closes its books or declares a record date (1) with respect to any
         dividend or distribution upon (or any subdivision, combination or other
         change in the outstanding number of shares of) any class of the
         Company's capital stock, (2) with respect to any pro rata subscription
         offer to holders of any class of the Company's capital stock or (3) for
         determining rights to vote with respect to any Organic Change,
         dissolution or liquidation.

                           (C) The Company also give written notice to the
         holder hereof at least 30 days prior to the date on which the Next
         Financing or any Organic Change will take place.

         The invalidity, or unenforceability in particular circumstances, of any
provision of this Note shall not extend beyond such provision or such
circumstances and no other provision of this Note shall be affected thereby. It
is expressly stipulated and agreed to be the intent of the Company and Payee at
all times to comply with applicable state law governing the maximum rate or
amount of interest payable on or in connection with this Note (or applicable
United States federal law to the extent that it permits Payee to contract for,
charge, take, reserve or receive a greater amount of interest than under state
law). If the applicable law is ever judicially interpreted so as to render
usurious any amount called for under this Note or under any of the other
documents evidencing, securing or relating to this Note or any part thereof
(collectively, the "Note Documents"), or contracted for, charged, taken,
reserved or received with respect to the indebtedness evidenced by this Note
(the "Loan"), or if any prepayment by the Company results in the Company having
paid any interest in excess of that permitted by law, then it is the Company's
and Payee's express intent that all excess amounts theretofore collected by
Payee be credited on the principal balance of this Note (or, if this Note has
been or would thereby be paid in full, refunded to the Company), and the
provisions of this Note and the other Note Documents immediately be deemed
reformed and the amounts thereafter collectible hereunder and thereunder
reduced, without the necessity of the execution of any new document, so as to
permit the recovery of the fullest amount called for hereunder and thereunder,
while complying in all respects with the applicable law and regulations. All
sums paid or agreed to be paid to Payee for the use, forbearance or detention of
the Loan shall, to the extent permitted by applicable law, be amortized,
prorated, allocated and spread throughout the full term of the Note until
payment in full so that the rate or amount of interest on account of the Note
does not exceed the applicable usury ceiling. Notwithstanding any provision
contained in this Note or in the Note Documents that permits the compounding of
interest, including without limitation any provision by which any of the accrued
interest is added to the principal amount of this Note, the total amount of
interest that the Company is obligated to pay and Payee is entitled to receive
with respect to this Note shall not exceed the amount calculated on a simple
(i.e., non-compounded) interest basis at the maximum allowable rate on principal
amounts actually advanced to or for the account of the Company.

         The Company and each surety, endorser, guarantor, and other party, if
any, now or hereafter liable for payment of any sums of money payable on this
Note, jointly and severally, waive presentment and demand for payment, notice of
intent to accelerate and notice of acceleration, protest and notice of protest
and nonpayment, and diligence in collecting or bringing suit against any party
liable hereon, and agree that their liability on this Note shall not be affected
by any

renewal or extension in time of payment hereof, by any indulgence, or by any
release, modification, or substitution of any security for the payment of this
Note, and hereby consent to any and all extensions, renewals, replacements,
waivers, releases, or exchanges affecting this Note and the taking, release,
modification, or substitution of any security, with or without notice and before
or after maturity.

         This Note shall be binding upon and inure to the benefit of the
Company, its successors and assigns, and shall inure to the benefit of the
Payee, its successors and permitted assigns. In the event this Note is placed in
the hands of an attorney for collection or suit is filed hereon or if
proceedings are had in bankruptcy, receivership, reorganization, or other legal
or judicial proceedings for the collection hereof, the Company hereby agrees to
pay to the holder of this Note reasonable attorneys' fees, and shall pay all
additional reasonable costs and expenses of collection and enforcement.

         THE SUBSTANTIVE LAWS OF THE STATE OF TEXAS SHALL GOVERN THE VALIDITY,
CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THIS NOTE WITHOUT REGARD TO
CONFLICT OF LAWS PROVISIONS.

         IN WITNESS WHEREOF, the Company has caused its duly authorized officer
to execute this Note as of the day and year first written above.

                                     WAIVER

     Reference is hereby made to that certain Wireless, Inc. Convertible
Promissory Note, dated as of August 17, 1999, in the principal amount of
$1,000,000 (the "Note") issued by Wireless, Inc., a California Corporation (the
"Company") in favor of AMT Capital, Ltd., a Texas limited partnership ("AMT").
Capitalized terms used but not defined herein shall have the meaning given to
such terms in the Note.

     Pursuant to Paragraph (b)(i) of the Note, the Preferred Stock Conversion
Price and the Common Stock Conversion Price, are subject to adjustment upon the
issuance of Preferred Stock or Common Stock of the Company, or options, warrants
or rights to purchase Preferred Stock or Common Stock of the Company,
respectively, at a price per share that is less than the then current Preferred
Stock Conversion Price or Common Stock Conversion Price, as applicable.

     The Company and certain investors are entering into a Securities Purchase

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

                            WARRANT TO PURCHASE STOCK

Corporation: Wireless, Inc., a California corporation
Number of Shares: 4% Warrant Coverage
Class of Stock: Series D Preferred
Initial Exercise Price: The price given at the close of the Series D Preferred
offering.
Issue Date: October 16, 1998
Expiration Date: October 16, 2003

         THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, SILICON VALLEY BANK ("Holder") is
entitled to purchase the number of fully paid and nonasssessable shares of the
class of securities (the "Shares") of the corporation (the "Company") at the
initial exercise price per Share (the "Warrant Price") all as set forth above
and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions
and upon the terms and conditions set forth in this Warrant. For purposes of
determining the Number of Shares, Warrant Coverage shall be defined as
$1,500,000.00 divided by the Initial Exercise Price multiplied by 4%.

ARTICLE 1. EXERCISE.

            1.1 METHOD OF EXERCISE. Holder may exercise this Warrant by
delivering a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

            1.2 CONVERSION RIGHT. In lieu of exercising this Warrant as
specified in Section 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined by dividing (a) the
aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share. The fair market value of the Shares
shall be determined pursuant to Section 1.4.

            1.3 INTENTIONALLY OMITTED.

            1.4 FAIR MARKET VALUE. If the Shares are traded in a public
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not traded in a public
market, the Board of Directors of the Company shall determine fair market value
in its reasonable good faith judgment. The foregoing notwithstanding, if Holder
advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment banking firm to undertake such valuation. If the valuation of such
investment banking firm is greater than that determined by the Board of
Directors, then all fees and expenses of such investment banking firm shall be
paid by the Company. In all other circumstances, such fees and expenses shall be
paid by Holder.

            1.5 DELIVERY OF CERTIFICATE AND NEW WARRANT. Promptly after
Holder exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

                                       1

<PAGE>

            1.6 REPLACEMENT OF WARRANTIES. On receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of loss, theft or destruction, on
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense shall execute and deliver, in lieu of this
Warrant, a new warrant of like tenor.

            1.7 REPURCHASE ON SALE, MERGER, OR CONSOLIDATION OF THE COMPANY.

                1.7.1.   "ACQUISITION".  For the purpose of this Warrant,
"Acquisition" means any sale, license, or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

                1.7.2.   ASSUMPTION OF WARRANT.  Upon the closing of any
Acquisition the successor entity shall assume the obligations of this Warrant,
and this Warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the
unexercised portion of this Warrant as if such Shares were outstanding on the
record date for the Acquisition and subsequent closing. The Warrant Price shall
be adjusted accordingly.

                1.7.3.   PURCHASE  RIGHT.  Notwithstanding  the  foregoing,  at
the election of Holder, the Company shall purchase the unexercised portion of
this Warrant for cash upon the closing of any Acquisition for an amount equal to
(a) the fair market value of any consideration that would have been received by
Holder in consideration of the Shares had Holder exercised the unexercised
portion of this Warrant immediately before the record date for determining the
shareholders entitled to participate in the proceeds of the Acquisition, less
(b) the aggregate Warrant Price of the Shares, but in no event less than zero.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

            2.1 STOCK DIVIDENDS, SPLITS, ETC. If the Company declares or pays a
dividend on its common stock (or the Shares if the Shares are securities other
than common stock) payable in common stock, or other securities, subdivides the
outstanding common stock into a greater amount of common stock, or, if the
Shares are securities other than common stock, subdivides the Shares in a
transaction that increases the amount of common stock into which the Shares are
convertible, then upon exercise of this Warrant, for each Share acquired, Holder
shall receive, without cost to Holder, the total number and kind of securities
to which Holder would have been entitled had Holder owned the Shares of record
as of the date the dividend or subdivision occurred.

            2.2 RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. Upon any
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event. Such an event shall include any automatic conversion of the
outstanding or issuable securities of the Company of the same class or series as
the Shares to common stock pursuant to the terms of the Company's Articles of
Incorporation upon the closing of a registered public offering of the Company's
common stock. The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property. The new Warrant shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2 including, without limitation,
adjustments to the Warrant Price and to the number of securities or property
issuable upon exercise of the new Warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, exchanges, substitutions,
or other events.

                                       2
<PAGE>

            2.3 ADJUSTMENTS FOR COMBINATIONS, ETC. If the outstanding Shares
are combined or consolidated, by reclassification or otherwise, into a lesser
number of shares, the Warrant Price shall be proportionately increased.

            2.4 ADJUSTMENTS FOR DILUTING ISSUANCES. The Warrant Price and
the number of Shares issuable upon exercise of this Warrant or, if the Shares
are Preferred Stock, the number of shares of common stock issuable upon
conversion of the Shares, shall be subject to adjustment, from time to time in
the manner set forth on Exhibit A in the event of Diluting Issuances (as defined
on Exhibit A).

            2.5 NO IMPAIRMENT. The Company shall not, by amendment of its
Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this Warrant by the Company, but
shall at all times in good faith assist in carrying out of all the provisions of
this Article 2 and in taking all such action as may be necessary or appropriate
to protect Holder's rights under this Article against impairment. If the Company
takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this Warrant, the
Warrant Price shall be adjusted downward and the number of Shares Issuable upon
exercise of this Warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this Warrant is unchanged.

            2.6 FRACTIONAL SHARES. No fractional Shares shall be issuable
upon exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional share interest
arises upon any exercise or conversion of the Warrant, the Company shall
eliminate such fractional share interest by paying Holder amount computed by
multiplying the fractional interest by the fair market value of a full Share.

            2.7 CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish Holder with a certificate of its Chief Financial Officer
setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting
forth the Warrant Price in effect upon the date thereof and the series of
adjustments leading to such Warrant Price.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

         In the event of the issuance (a "Diluting Issuance") by the Company,
after the Issue Date of the Warrant, of securities at a price per share less
than the Warrant Price, then the number of shares of common stock issuable upon
conversion of the Shares shall be adjusted in accordance with those provisions
(the "Provisions") of the Company's Articles (Certificate) of Incorporation
which apply to Diluting Issuances.

         The Company agrees that the Provisions, as in effect on the Issue Date,
shall be deemed to remain in full force and effect during the term of the
Warrant notwithstanding any subsequent amendment, waiver or termination thereof
by the Company's shareholders.

         Under no circumstances shall the aggregate Warrant Price payable by the
Holder upon exercise of the Warrant increase as a result of any adjustment
arising from a Diluting Issuance.

                               REGISTRATION RIGHTS

         The Shares (if common stock), or the common stock issuable upon

entitled to "piggy back" registration rights in accordance with the terms of the
following agreement (the "Agreement") between the Company and its investor(s):

                  [Identify Agreement by date, title and parties. If no
                  Agreement exists, indicate by "none".]

         The Company agrees that no amendments will be made to the Agreement
which would have an adverse impact on Holder's registration rights thereunder
without the consent of Holder. By acceptance of the Warrant to which this
Exhibit B is attached, Holder shall be deemed to be a party to the Agreement,
unless Holder otherwise elects not to become or to cease being a party thereto.

         If no Agreement exists, then the Company and the Holder Shall enter
into Holder's standard form of Registration Rights Agreement as in effect on the
Issue Date of the Warrant.

                               SILICON VALLEY BANK
                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT is entered into as of October 16,
1998, by and between Silicon Valley Bank ("Purchaser") and the Company whose
name appears on the last page of this Agreement.

                                    RECITALS

         A. Concurrently with the execution of this Agreement, the Purchaser is
purchasing from the Company a Warrant to Purchase Stock (the "Warrant") pursuant
to which Purchaser has the right to acquire from the Company the Shares (as
defined in the Warrant).

         B. By this  Agreement,  the Purchaser and the Company desire to set
forth the  registration  rights of the Shares all as provided herein.

            NOW, THEREFORE, in consideration of the mutual promises,
covenants and conditions hereinafter set forth, the parties hereto mutually
agree as follows:

         1. REGISTRATION RIGHTS. The Company covenants and agrees as follows:

            1.1   DEFINITIONS. For purposes of this Section 1:

                  (a)   The  term  "register,"  "registered,"  and
"registration" refer to a registration effected by preparing and filing a
registration statement or similar document in compliance with the Securities Act
of 1933, as amended (the "Securities Act"), and the declaration or ordering of
effectiveness of such registration statement or document;

                  (b)   The term  "Registrable  Securities"  means (i) the
Shares (if Common Stock) or all shares of Common Stock of the Company issuable
or issued upon conversion of the Shares and (ii) any Common Stock of the Company
issued as (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued as) a dividend or other distribution with respect
to, or in exchange for or in replacement of, any stock referred to in (i).

                  (c)    The terms "Holder" or "Holders" means the Purchaser
or qualifying transferees under subsection 1.8 thereof who hold Registrable
Securities.

                  (d)    The term "SEC" means the Securities and Exchange
Commission.

            1.2   COMPANY REGISTRATION.

                  (a)    REGISTRATION.  If at any time or from time to time,
the Company shall  determine to register any of its securities, for its own
account or the account of any of its shareholders, other than a registration on
Form S-l or S-8 relating solely to employee stock option or purchase plans, or
a registration on Form S-4 relating solely to an SEC Rule 145 transaction, or
a registration on any other form (other than Form S-l, S-2, S-3 or S-18, or
their successor forms) or any successor to such forms, which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities, the
Company will:

                          (i)   promptly  give to each Holder  written  notice
thereof (which shall include a list of the jurisdictions in which the Company
intends to attempt to qualify such securities under the applicable blue sky or
other state securities laws); and
<PAGE>

                          (ii)  include in such registration (and  compliance),
and in any underwriting involved therein, all the Registrable Securities
specified in a written request or requests, made within 30 days after receipt of
such written notice from the Company, by any Holder or Holders, except as set
forth in subsection 1.2(b) below.

                    (b)   UNDERWRITING.  If the  registration  of which the
Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written
notice given pursuant to subsection 1.2(a)(i). In such event the right of any
Holder to registration pursuant to this subsection 1.2 shall be conditioned upon
such Holder's participation in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting to the extent provided
herein. All Holders proposing to distribute their securities through such
underwriting shall (together with the Company and the other shareholders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company.

            1.3     EXPENSES OF REGISTRATION. All expenses incurred in
connection with any registration, qualification or compliance pursuant to this
Section 1 including without limitation, all registration, filing and
qualification fees, printing expenses, fees and disbursements of counsel for the
Company and expenses of any special audits incidental to or required by such
registration, shall be borne by the Company except the Company shall not be
required to pay underwriters fees, discounts or commissions relating to
Registrable Securities. All expenses of any registered offering not otherwise
borne by the Company shall be borne pro rata among the Holders participating in
the offering and the Company.

            1.4     REGISTRATION PROCEDURES. In the case of each registration,
qualification or compliance effected by the Company pursuant to this
Registration Rights Agreement, the Company will keep each Holder participating
therein advised in writing as to the initiation of each registration,
qualification and compliance and as to the completion thereof. Except as
otherwise provided in subsection 1.3, at its expense the Company will:

                    (a)   Prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use its best efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep
such registration statement effective for up to 120 days.

                    (b)   Prepare and file with the SEC such  amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

                    (c)   Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                    (d)   Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therewith
or as a condition thereto qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.


                                        2
<PAGE>

                    (e)   In the event of any underwritten  public offering,
enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement

                    (f)   Notify each Holder of Registrable  Securities  covered
by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act or the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

            1.5     INDEMNIFICATION.

                    (a) The Company will indemnify each Holder of Registrable
Securities and each of its officers, directors and partners, and each person
controlling such Holder, with respect to which such registration, qualification
or compliance has been effected pursuant to this Rights Agreement, and each
underwriter, if any, and each person who controls any underwriter of the
Registrable Securities held by or issuable to such Holder, against all claims,
losses, expenses, damages and liabilities (or actions in respect thereto)
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any prospectus, offering circular or offer document
(including any related registration statement, notification or the like)
incident to any such registration, qualification or compliance, or based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statement therein not misleading, or any
violation or alleged violation by the Company of the Securities Act, the
Securities Exchange Act of 1934, as amended, ("Exchange Act") or any state
securities law applicable to the Company or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any such state law and relating to
action or inaction required of the Company in connection with any such
registration, qualification of compliance, and will reimburse each such Holder.
each of its officers, directors and partners, and each person controlling such
Holder, each such underwriter and each person who controls any such underwriter,
within a reasonable amount of time after incurred for any reasonable legal and
any other expenses incurred in connection with investigating, defending or
settling any such claim, loss, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection 1.5(a) shall not apply
to amounts paid in settlement of any such claim, loss, damage, liability, or
action if such settlement is effected without the consent of the Company (which
consent shall not be unreasonably withheld); and provided further, that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage or liability arises out of or is based on any untrue statement or
omission based upon written information furnished to the Company by an
instrument duly executed by such Holder or underwriter specifically for use
therein.

                    (b)   Each Holder will, if Registrable  Securities held by
or issuable to such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify the
Company, each of its directors and officers, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company within the meaning of the Securities Act, and each other
such Holder, each of its officers, directors and partners and each person
controlling such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement, prospectus, offering circular or other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company, such Holders, such directors,
officers, partners, persons or underwriters for any reasonable legal or any
other expenses incurred in connection with investigating, defending or settling
any such claim, loss, damage, liability or action, in each case to the extent,
but only to the extent, that such untrue statement (or alleged untrue statement)
or omission (or alleged omission) is made in such registration statement,

                                       3
<PAGE>

prospectus, offering circular or other document in reliance upon and in
conformity with written information furnished to the Company by an instrument
duly executed by such Holder specifically for use therein; provided, however,
that the indemnity agreement contained in this subsection 1.5(b) shall not apply
to amounts paid in settlement of any such claim, loss, damage, liability or
action if such settlement is effected without the consent of the Holder, (which
consent shall not be unreasonably withheld); and provided further, that the
total amount for which any Holder shall be liable under this subsection 1.5(b)
shall not in any event exceed the aggregate proceeds received by such Holder
from the sale of Registrable Securities held by such Holder in such
registration.

                    (c)   Each party entitled to  indemnification  under this
subsection 1.5 (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at such party's expense; and provided further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
indemnifying Party of its obligations hereunder, unless such failure resulted in
prejudice to the Indemnifying Party; and provided further, that an Indemnified
Party (together with all other Indemnified Parties which may be represented
without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the Indemnifying Party, if
representation of such indemnified Party by the counsel retained by the
Indemnifying Party would be inappropriate due to actual or potential differing
interests between such indemnified Party and any other party represented by such
counsel in such proceeding. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation.

            1.6     INFORMATION BY HOLDER. Any Holder or Holders of
Registrable Securities included in any registration shall promptly furnish to
the Company such information regarding such Holder or Holders and the
distribution proposed by such Holder or Holders as the Company may request in
writing and as shall be required in connection with any registration,
qualification or compliance referred to herein.

            1.7     RULE 144 REPORTING. With a view to making available to
Holders the benefits of certain rules and regulations of the SEC which may
permit the sale of the Registrable Securities to the public without
registration, the Company agrees at all times to:

                    (a)   make and keep public information  available,  as those
terms are understood and defined in SEC Rule 144, after 90 days after the
effective date of the first registration filed by the Company for an offering of
its securities to the general public;

                    (b)   file with the SEC in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements); and

                    (c)   so long as a Holder owns any Registrable  Securities,
to furnish to such Holder forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144
(at any time after 90 days after the effective date of the first registration
statement filed by the Company for an offering of its securities to the general
public), and of the Securities Act and the Exchange Act (at any time after it
has become subject to such reporting requirements), a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
so

                                       4
<PAGE>

filed by the Company as the Holder may reasonably request in complying with any
rule or regulation of the SEC allowing the Holder to sell any such securities
without registration.

            1.8     TRANSFER OF REGISTRATION RIGHTS. Holders' rights to cause
the Company to register their securities and keep information available, granted
to them by the Company under subsections 1.2 and 1.7 may be assigned to a
transferee or assignee of a Holder's Registrable Securities not sold to the
public, provided, that the Company is given written notice by such Holder at the
time of or within a reasonable time after said transfer, stating the name and
address of said transferee or assignee and identifying the securities with
respect to which such registration rights are being assigned. The Company may
prohibit the transfer of any Holders' rights under this subsection 1.8 to any
proposed transferee or assignee who the Company reasonably believes is a
competitor of the Company.

         2.     GENERAL.

            2.1     WAIVERS AND AMENDMENTS. With the written consent of the
record or beneficial holders of at least a majority of the Registrable
Securities, the obligations of the Company and the rights of the Holders of the
Registrable Securities under this agreement may be waived (either generally or
in a particular instance, either retroactively or prospectively, and either for
a specified period of time or indefinitely), and with the same consent the
Company, when authorized by resolution of its Board of Directors, may enter into
a supplementary agreement for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement;
provided, however, that no such modification, amendment or waiver shall reduce
the aforesaid percentage of Registrable Securities without the consent of all of
the Holders of the Registrable Securities. Upon the effectuation of each such
waiver, consent, agreement of amendment or modification, the Company shall
promptly give written notice thereof to the record holders of the Registrable
Securities who have not previously consented thereto in writing. This Agreement
or any provision hereof may be changed, waived, discharged or terminated only by
a statement in writing signed by the party against which enforcement of the
change, waiver, discharge or termination is sought, except to the extent
provided in this subsection 2. 1.

             2.2    GOVERNING LAW. This Agreement shall be governed in all
respects by the laws of the State of California as such laws are applied to
agreements between California residents entered into and to be performed
entirely within California.

enforceability of the remaining provisions of this Agreement or any provision of

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO
THE CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.


                            WARRANT TO PURCHASE STOCK

              Corporation: WIRELESS, INC., A CALIFORNIA CORPORATION
                         Number of Shares: 20,000 SHARES
                    Class of Stock: PREFERRED STOCK, SERIES E
                     Initial Exercise Price: $2.50 PER SHARE
                         Issue Date: SEPTEMBER 13, 1999
                       Expiration Date: SEPTEMBER 13, 2004

     THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, SILICON VALLEY BANK ("Holder") is
entitled to purchase the number of fully paid and nonassessable shares of the
class of securities (the "Shares") of the corporation (the "Company") at the
initial exercise price per Share (the "Warrant Price") all as set forth above
and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions
and upon the terms and conditions set forth in this Warrant.

ARTICLE 1. EXERCISE.

          1.1 METHOD OF EXERCISE. Holder may exercise this Warrant by delivering
a duly executed Nonce of Exercise in substantially the form attached as Appendix
1 to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

          1.2 CONVERSION RIGHT. In lieu of exercising this Warrant as specified
in Section 1.1, Holder may from time to time convert this Warrant, in whole or
in part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.4.

          1.3 INTENTIONALLY OMITTED

          1.4 FAIR MARKET VALUE. If the Shares are traded in a public market,
the fair market value of the Shares shall be the closing price of the Shares (or
the closing price of the Company's stock into which the Shares are convertible)
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not


<PAGE>

traded in a public market, the Board of Directors of the Company shall determine
fair market value in its reasonable good faith judgment. The foregoing
notwithstanding, if Holder advises the Board of Directors in writing that Holder
disagrees with such determination, then the Company and Holder shall promptly
agree upon a reputable investment banking firm to undertake such valuation. If
the valuation of such investment banking firm is greater than that determined by
the Board of Directors, then all fees and expenses of such investment banking
firm shall be paid by the Company. In all other circumstances, such fees and
expenses shall be paid by Holder.

          1.5 DELIVERY OF CERTIFICATE AND NEW WARRANT. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

          1.6 REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

          1.7 REPURCHASE ON SALE, MERGER, OR CONSOLIDATION OF THE COMPANY.

               1.7.1. "ACQUISITION". For the purpose of this Warrant,
"Acquisition" means any sale, license, or other disposition of all
or substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

               1.7.2. ASSUMPTION OF WARRANT. Upon the closing of any Acquisition
the successor entity shall assume the obligations of this Warrant, and this
Warrant shall be exercisable for the same securities, cash, and property as
would be payable for the Shares issuable upon exercise of the unexercised
portion of this Warrant as if such Shares were outstanding on the record date
for the Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

               1.7.3. PURCHASE RIGHT. Notwithstanding the foregoing, at the
election of Holder, the Company shall purchase the unexercised portion of this
Warrant for cash upon the closing of any Acquisition for an amount equal to (a)
the fair marker value of any consideration that would have been received by
Holder in consideration of the Shares had Holder exercised the unexercised
portion of this Warrant immediately before the record date for determining the
shareholders entitled to participate in the proceeds of the Acquisition, less
(b) the aggregate Warrant Price of the Shares, but in no event less than zero.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

<PAGE>

          2.1 STOCK DIVIDENDS, SPLITS, ETC. If the Company declares or
pays a dividend on its common stock (or the Shares if the Shares are securities
other than common stock) payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
or, if the Shares are securities other than common stock, subdivides, the Shares
in a transaction that increases the amount of common stock into which the Shares
are convertible, then upon exercise of this Warrant, for each Share acquired,
Holder shall receive, without cost to Holder, the total number and kind of
securities to which Holder would have been entitled had Holder owned the Shares
of record as of the date the dividend or subdivision occurred.

          2.2 RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. Upon any
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares, if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event. Such an event shall include any automatic conversion of the
outstanding or issuable securities of the Company of the same class or series as
the Shares to common stock pursuant to the terms of the Company's Articles of
Incorporation upon the closing of a registered public offering of the Company's
common stock. The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property. The new Warrant shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2 including, without limitation,
adjustments to the Warrant Price, and to the number of securities or property
issuable upon exercise of the new Warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, exchanges, substitution,
or other events.

          2.3 ADJUSTMENTS FOR COMBINATIONS, ETC. If the outstanding Shares are
combined or consolidated by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

          2.4 ADJUSTMENTS FOR DILUTING ISSUANCES. The Warrant Price and the
number of Shares issuable upon exercise of this Warrant or, if the Shares are
Preferred Stock, the number of shares of common stock issuable upon conversion
of the Shares, shall be subject to adjustment, from time to time in the manner
set forth on Exhibit A in the event of Diluting Issuances (as defined on Exhibit
A).


                                       3
<PAGE>

          2.5 NO IMPAIRMENT. The Company shall not, by amendment of its Articles
of Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

          2.6 FRACTIONAL SHARES. No fractional Shares shall be issuable upon
exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional share interest
arises upon any exercise or conversion of the Warrant, the Company shall
eliminate such fractional share interest by paying Holder amount computed by
multiplying the fractional interest by the fair market value of a full Share.

          2.7 CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.

                               GENERAL PROVISIONS

            I.    PURPOSE OF THE PLAN

                  This 2000 Stock Incentive Plan is intended to promote the
interests of Wireless, Inc., a Delaware corporation, by providing eligible
persons with the opportunity to acquire a proprietary interest, or otherwise
increase their proprietary interest, in the Corporation as an incentive for them
to remain in the service of the Corporation.

                  Capitalized terms shall have the meanings assigned to such
terms in the attached Appendix.

            II.   STRUCTURE OF THE PLAN

                  A. The Plan shall be divided into five separate equity

                  Administrator, be granted options to purchase shares of Common
                  Stock,

                  base salary invested each year in special options,

                        (iii) the Stock Issuance Program under which eligible
                  persons may, at the discretion of the Plan Administrator, be
                  issued shares of Common Stock directly, either through the
                  immediate purchase of such shares or as a bonus for services
                  rendered the Corporation (or any Parent or Subsidiary),

                        (iv) the Automatic Option Grant Program under which
                  eligible non-employee Board members shall automatically
                  receive options at periodic intervals to purchase shares of
                  Common Stock; and

                        (v) the Director Fee Option Grant Program under which

                  applied to a special option grant.

                  B. The provisions of Articles One and Seven shall apply to all
equity programs under the Plan and shall govern the interests of all persons
under the Plan.

            III.  ADMINISTRATION OF THE PLAN

                  A. The following provisions shall govern the administration of
the Plan:

                        (i) The Board shall have the authority to administer the
                  Discretionary Option Grant and Stock Issuance Programs with
                  respect to Section 16 Insiders but may delegate such authority
                  in whole or in part to the Primary Committee.

                        (ii) Administration of the Discretionary Option Grant
                  and Stock Issuance Programs with respect to all other persons
                  eligible to participate in those programs may, at the Board's
                  discretion, be vested in the Primary Committee or a Secondary
                  Committee, or the Board may retain the power to administer
                  those programs with respect to all such persons.

                        (iii) The Primary Committee shall have the sole and
                  exclusive authority to determine which Section 16 Insiders and
                  other highly compensated Employees shall be eligible for
                  participation in the Salary Investment Option Grant Program
                  for one or more calendar years. However, all option grants
                  under the Salary Investment Option Grant Program shall be made
                  in accordance with the express terms of that program, and the
                  Primary Committee shall not exercise any discretionary
                  functions with respect to the option grants made under that
                  program.

                        (iv) Administration of the Automatic Option Grant and
                  Director Fee Option Grant Programs shall be self-executing in
                  accordance with the terms of those programs.

                  B. Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full power and authority
subject to the provisions of the Plan:

                        (i) to establish such rules as it may deem appropriate
                  for proper administration of the Plan, to make all factual
                  determinations, to construe and interpret the provisions of
                  the Plan and the awards thereunder and to resolve any and all
                  ambiguities thereunder;

                        (ii) to determine, with respect to awards made under the
                  Discretionary Option Grant and Stock Issuance Programs, which
                  eligible persons are to receive such awards, the time or times
                  when such awards are to be made, the number of shares to be
                  covered by each such award, the vesting schedule (if any)
                  applicable to the award, the status of a granted option as
                  either an Incentive Option or a Non-Statutory Option and the
                  maximum term for which the option is to remain outstanding;

                        (iii) to amend, modify or cancel any outstanding award
                  with the consent of the holder or accelerate the vesting of
                  such award; and


                                       2
<PAGE>

                        (iv) to take such other discretionary actions as
                  permitted pursuant to the terms of the applicable program.

Decisions of each Plan Administrator within the scope of its administrative
functions under the Plan shall be final and binding on all parties.

                  C. Members of the Primary Committee or any Secondary Committee
shall serve for such period of time as the Board may determine and may be
removed by the Board at any time. The Board may also at any time terminate the
functions of any Secondary Committee and reassume all powers and authority
previously delegated to such committee.

                  D. Service on the Primary Committee or the Secondary Committee
shall constitute service as a Board member, and members of each such committee
shall accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any options or stock issuances under the Plan.

            IV.   ELIGIBILITY

                  A. The persons eligible to participate in the Discretionary
Option Grant and Stock Issuance Programs are as follows:

                        (i) Employees,

                        (ii) non-employee members of the Board or the board of
                  directors of any Parent or Subsidiary, and

                        (iii) consultants and other independent advisors who
                  provide services to the Corporation (or any Parent or
                  Subsidiary).

                  B. Only Employees who are Section 16 Insiders or other highly
compensated individuals shall be eligible to participate in the Salary
Investment Option Grant Program.

                  C. Only non-employee Board members shall be eligible to
participate in the Automatic Option Grant and Director Fee Option Grant
Programs.

            V.    STOCK SUBJECT TO THE PLAN

                  A. The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares repurchased
by the Corporation on the open market. The maximum number of shares of Common
Stock initially reserved for issuance over the term of the Plan shall not exceed
[8,750,000] shares. Such authorized share reserve consists of (i) the number of
shares which remain available for issuance, as of the Plan Effective Date, under
the Predecessor Plan, including the shares subject to the outstanding options to
be incorporated into the Plan and the additional shares which would otherwise be
available for future grant, plus (ii) an increase of [ ] shares authorized by
the Board subject to stockholder approval prior to the Section 12 Registration
Date.


                                       3
<PAGE>

                  B. The number of shares of Common Stock available for issuance
under the Plan shall automatically increase on the first trading day of each
calendar year during the term of the Plan, beginning with the 2001 calendar
year, by an amount equal to [three percent (3%)] of the shares of Common Stock
outstanding on the last trading day of the immediately preceding calendar year,
but in no event shall any such annual increase exceed [ ] shares.

                  C. No one person participating in the Plan may receive
options, separately exercisable stock appreciation rights and direct stock
issuances for more than [ ] shares of Common Stock in the aggregate per calendar
year, beginning with the 2000 calendar year.

                  D. Shares of Common Stock subject to outstanding options
(including options incorporated into this Plan from the Predecessor Plan) shall
be available for subsequent issuance under the Plan to the extent those options
expire, terminate or are cancelled for any reason prior to exercise in full.
Unvested shares issued under the Plan and subsequently repurchased by the
Corporation, at the original exercise or issue price paid per share, pursuant to
the Corporation's repurchase rights under the Plan shall be added back to the
number of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent options
or direct stock issuances under the Plan. However, should the exercise price of
an option under the Plan be paid with shares of Common Stock or should shares of
Common Stock otherwise issuable under the Plan be withheld by the Corporation in
satisfaction of the withholding taxes incurred in connection with the exercise
of an option or the vesting of a stock issuance under the Plan, then the number
of shares of Common Stock available for issuance under the Plan shall be reduced
by the gross number of shares for which the option is exercised or which vest
under the stock issuance, and not by the net number of shares of Common Stock
issued to the holder of such option or stock issuance. Shares of Common Stock
underlying one or more stock appreciation rights exercised under the Plan shall
NOT be available for subsequent issuance.

                  E. If any change is made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and/or class of securities issuable
under the Plan, (ii) the number and/or class of securities by which the share
reserve is to increase each calendar year pursuant to the automatic share
increase provisions of the Plan, (iii) the number and/or class of securities for
which any one person may be granted options, separately exercisable stock
appreciation rights and direct stock issuances under the Plan per calendar year,
(iv) the number and/or class of securities for which grants are subsequently to
be made under the Automatic Option Grant Program to new and continuing
non-employee Board members, (v) the number and/or class of securities and the
exercise price per share in effect under each outstanding option under the Plan
and (vi) the number and/or class of securities and price per share in effect
under each outstanding option incorporated into this Plan from the Predecessor
Plan. Such adjustments to the outstanding options are to be effected in a manner
which shall preclude the enlargement or dilution of rights and benefits under
such options. The adjustments determined by the Plan Administrator shall be
final, binding and conclusive.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM

            I.    OPTION TERMS

                  Each option shall be evidenced by one or more documents in the
form approved by the Plan Administrator; PROVIDED, however, that each such
document shall comply with the terms specified below. Each document evidencing
an Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

                  A. EXERCISE PRICE.

                        1. The exercise price per share shall be fixed by the
                  Plan Administrator at the time of the option grant, but shall
                  not be less than one hundred percent (100%) of the Fair Market
                  Value per share of Common Stock on the grant date.

                        2. The exercise price shall become immediately due upon
                  exercise of the option and shall, subject to the provisions of
                  Section II of Article Seven and the documents evidencing the
                  option, be payable in cash or check made payable to the
                  Corporation. Should the Common Stock be registered under
                  Section 12 of the 1934 Act at the time the option is
                  exercised, then the exercise price may also be paid as
                  follows:

                              (i) shares of Common Stock held for the requisite
                        period necessary to avoid a charge to the Corporation's
                        earnings for financial reporting purposes and valued at
                        Fair Market Value on the Exercise Date, or

                              (ii) to the extent the option is exercised for
                        vested shares, through a special sale and remittance
                        procedure pursuant to which the Optionee shall
                        concurrently provide irrevocable instructions to (a) a
                        Corporation-approved brokerage firm to effect the
                        immediate sale of the purchased shares and remit to the
                        Corporation, out of the sale proceeds available on the
                        settlement date, sufficient funds to cover the aggregate
                        exercise price payable for the purchased shares plus all
                        applicable Federal, state and local income and
                        employment taxes required to be withheld by the
                        Corporation by reason of such exercise and (b) the
                        Corporation to deliver the certificates for the
                        purchased shares directly to such brokerage firm in
                        order to complete the sale.

                  Except to the extent such sale and remittance procedure is
                  utilized, payment of the exercise price for the purchased
                  shares must be made on the Exercise Date.

                  B. EXERCISE AND TERM OF OPTIONS. Each option shall be
exercisable at such time or times, during such period and for such number of
shares as shall be determined by the Plan Administrator and set forth in the
documents evidencing the option. However, no option shall have a term in excess
of ten (10) years measured from the option grant date.

                  C. CESSATION OF SERVICE.


                                       5
<PAGE>

                        1. The following provisions shall govern the exercise of
                  any options outstanding at the time of the Optionee's
                  cessation of Service or death:

                              (i) Any option outstanding at the time of the
                        Optionee's cessation of Service for any reason shall
                        remain exercisable for such period of time thereafter as
                        shall be determined by the Plan Administrator and set
                        forth in the documents evidencing the option, but no
                        such option shall be exercisable after the expiration of
                        the option term.

                              (ii) Any option exercisable in whole or in part by
                        the Optionee at the time of death may be subsequently
                        exercised by his or her Beneficiary.

                              (iii) During the applicable post-Service exercise
                        period, the option may not be exercised in the aggregate
                        for more than the number of vested shares for which the
                        option is exercisable on the date of the Optionee's
                        cessation of Service. Upon the expiration of the
                        applicable exercise period or (if earlier) upon the
                        expiration of the option term, the option shall
                        terminate and cease to be outstanding for any vested
                        shares for which the option has not been exercised.
                        However, the option shall, immediately upon the
                        Optionee's cessation of Service, terminate and cease to
                        be outstanding to the extent the option is not otherwise
                        at that time exercisable for vested shares.

                              (iv) Should the Optionee's Service be terminated
                        for Misconduct or should the Optionee engage in
                        Misconduct while his or her options are outstanding,
                        then all such options shall terminate immediately and
                        cease to be outstanding.

                        2. The Plan Administrator shall have complete
                  discretion, exercisable either at the time an option is
                  granted or at any time while the option remains outstanding:

                              (i) to extend the period of time for which the
                        option is to remain exercisable following the Optionee's
                        cessation of Service to such period of time as the Plan
                        Administrator shall deem appropriate, but in no event
                        beyond the expiration of the option term, and/or

                              (ii) to permit the option to be exercised, during
                        the applicable post-Service exercise period, for one or
                        more additional installments in which the Optionee would
                        have vested had the Optionee continued in Service.

                  D. STOCKHOLDER RIGHTS. The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

                  E. REPURCHASE RIGHTS. The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms


                                       6
<PAGE>

upon which such repurchase right shall be exercisable (including the period and
procedure for exercise and the appropriate vesting schedule for the purchased
shares) shall be established by the Plan Administrator and set forth in the
document evidencing such repurchase right.

                  F. LIMITED TRANSFERABILITY OF OPTIONS. During the lifetime of
the Optionee, Incentive Options shall be exercisable only by the Optionee and
shall not be assignable or transferable other than to a Beneficiary following
the Optionee's death. Non-Statutory Options shall be subject to the same
restrictions, except that a Non-Statutory Option may, to the extent permitted by
the Plan Administrator, be assigned in whole or in part during the Optionee's
lifetime (i) as a gift to one or more members of the Optionee's immediate
family, to a trust in which Optionee and/or one or more such family members hold
more than fifty percent (50%) of the beneficial interest or to an entity in
which more than fifty percent (50%) of the voting interests are owned by one or
more such family members or (ii) pursuant to a domestic relations order. The
terms applicable to the assigned portion shall be the same as those in effect
for the option immediately prior to such assignment and shall be set forth in
such documents issued to the assignee as the Plan Administrator may deem
appropriate.

            II.   INCENTIVE OPTIONS

                  The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Six shall be applicable to Incentive
Options. Options which are specifically designated as Non-Statutory Options when
issued under the Plan shall NOT be subject to the terms of this Section II.

                  A. ELIGIBILITY. Incentive Options may only be granted to
Employees.

                  B. EXERCISE PRICE. The exercise price per share shall not be
less than one hundred percent (100%) of the Fair Market Value per share of
Common Stock on the option grant date.

                  C. DOLLAR LIMITATION. The aggregate Fair Market Value of the
shares of Common Stock (determined as of the respective date or dates of grant)
for which one or more options granted to any Employee under the Plan (or any
other option plan of the Corporation or any Parent or Subsidiary) may for the
first time become exercisable as Incentive Options during any one calendar year
shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

                  D. 10% STOCKHOLDER. If any Employee to whom an Incentive
Option is granted is a 10% Stockholder, then the exercise price per share shall
not be less than one hundred ten percent (110%) of the Fair Market Value per
share of Common Stock on the option grant date, and the option term shall not
exceed five (5) years measured from the option grant date.

            III.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

                  A. Each option outstanding at the time of a Change in Control
but not otherwise fully-vested shall automatically accelerate so that each such
option shall, immediately prior to the effective date of the Change in Control,
become exercisable for all of the shares of Common Stock at the time subject to
that option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock. However, an outstanding option shall not so accelerate
if and to the extent: (i) such option is, in connection with the Change in
Control, assumed or otherwise continued in full force and effect by the
successor corporation (or parent thereof) pursuant to the terms of the Change in
Control, (ii) such option is replaced with a cash incentive program of the
successor corporation which preserves the spread existing at the time of the
Change in Control on the shares of Common Stock for which the option is not
otherwise at that time exercisable and provides for subsequent payout in
accordance with the same vesting schedule applicable to those option shares or
(iii) the acceleration of such option is subject to other limitations imposed by
the Plan Administrator at the time of the option grant. Each option outstanding
at the time of the Change in Control shall terminate as provided in Section
III.C. of this Article Two.

                  B. All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Change in Control, except to
the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) or otherwise continue in full force and effect
pursuant to the terms of the Change in Control or (ii) such accelerated vesting
is precluded by other limitations imposed by the Plan Administrator at the time
the repurchase right is issued.

                  C. Immediately following the consummation of the Change in
Control, all outstanding options shall terminate and cease to be outstanding,
except to the extent assumed by the successor corporation (or parent thereof) or
otherwise expressly continued in full force and effect pursuant to the terms of
the Change in Control.

                  D. Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted, immediately after such Change in
Control, to apply to the number and class of securities which would have been
issuable to the Optionee in consummation of such Change in Control had the
option been exercised immediately prior to such Change in Control. Appropriate
adjustments to reflect such Change in Control shall also be made to (i) the
exercise price payable per share under each outstanding option, PROVIDED the
aggregate exercise price payable for such securities shall remain the same, (ii)
the maximum number and/or class of securities available for issuance over the
remaining term of the Plan and (iii) the maximum number and/or class of
securities for which any one person may be granted options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year.

                  E. The Plan Administrator may at any time provide that one or
more options will automatically accelerate in full or in part in connection with
a Change in Control, whether or not those options are assumed or otherwise
continued in full force and effect pursuant to the terms of the Change in
Control. Any such option shall accordingly become exercisable,


                                       8
<PAGE>

immediately prior to the effective date of such Change in Control, for all or
part of the shares of Common Stock at the time subject to that option and may be
exercised for some or all of those shares as fully-vested shares of Common
Stock. In addition, the Plan Administrator may at any time provide that one or
more of the Corporation's repurchase rights shall not be assignable in
connection with such Change in Control and shall terminate upon the consummation
of such Change in Control.

                  F. The Plan Administrator may at any time provide that one or
more options will automatically accelerate in full or in part upon an
Involuntary Termination of the Optionee's Service within a designated period
(not to exceed eighteen (18) months) following the effective date of any Change
in Control in which those options do not otherwise accelerate. Any options so
accelerated shall remain exercisable for fully-vested shares until the EARLIER
of (i) the expiration of the option term or (ii) the expiration of the one (1)
year period measured from the effective date of the Involuntary Termination. In
addition, the Plan Administrator may at any time provide that one or more of the
Corporation's repurchase rights shall immediately terminate upon such
Involuntary Termination.

                  G. The Plan Administrator may at any time provide that one or
more options will automatically accelerate in full or in part in connection with
a Hostile Take-Over. Any such option shall become exercisable, immediately prior
to the effective date of such Hostile Take-Over, for all or part of the shares
of Common Stock at the time subject to that option and may be exercised for some
or all of those shares as fully-vested shares of Common Stock. In addition, the
Plan Administrator may at any time provide that one or more of the Corporation's
repurchase rights shall terminate automatically upon the consummation of such
Hostile Take-Over. Alternatively, the Plan Administrator may condition such
automatic acceleration and termination upon an Involuntary Termination of the
Optionee's Service within a designated period (not to exceed eighteen (18)
months) following the effective date of such Hostile Take-Over. Each option so
accelerated shall remain exercisable for fully-vested shares until the
expiration or sooner termination of the option term.

                  H. The portion of any Incentive Option accelerated in
connection with a Change in Control or Hostile Take Over shall remain
exercisable as an Incentive Option only to the extent the applicable One Hundred
Thousand Dollar ($100,000) limitation is not exceeded. To the extent such dollar
limitation is exceeded, the accelerated portion of such option shall be
exercisable as a Non-Statutory Option under the Federal tax laws.

            IV.   STOCK APPRECIATION RIGHTS

                  The Plan Administrator may, subject to such conditions as it
may determine, grant to selected Optionees stock appreciation rights which will
allow the holders of those rights to elect between the exercise of the
underlying option for shares of Common Stock and the surrender of that option in
exchange for a distribution from the Corporation in an amount equal to the
excess of (a) the Option Surrender Value of the number of shares for which the
option is surrendered over (b) the aggregate exercise price payable for such
shares. The distribution may be made in shares of Common Stock valued at Fair
Market Value on the option surrender date, in cash, or partly in shares and
partly in cash, as the Plan Administrator shall in its sole discretion deem
appropriate.

                     SALARY INVESTMENT OPTION GRANT PROGRAM

            I.    OPTION GRANTS

                  The Primary Committee may implement the Salary Investment
Option Grant Program for one or more calendar years beginning after the
Underwriting Date and select the Section 16 Insiders and other highly
compensated Employees eligible to participate in the Salary Investment Option
Grant Program for each such calendar year. Each selected individual who elects
to participate in the Salary Investment Option Grant Program must, prior to the
start of each calendar year of participation, file with the Plan Administrator
(or its designate) an irrevocable authorization directing the Corporation to
reduce his or her base salary for that calendar year by an amount not less than
Ten Thousand Dollars ($10,000.00) nor more than Fifty Thousand Dollars
($50,000.00). The Primary Committee shall have complete discretion to determine
whether to approve the filed authorization in whole or in part. To the extent
the Primary Committee approves the authorization, the individual who filed that
authorization shall be granted an option under the Salary Investment Grant
Program on the first trading day in January for the calendar year for which the
salary reduction is to be in effect.

            II.   OPTION TERMS

                  Each option shall be a Non-Statutory Option evidenced by one
or more documents in the form approved by the Plan Administrator; PROVIDED,
however, that each such document shall comply with the terms specified below.

                  A. EXERCISE PRICE.

                        1. The exercise price per share shall be thirty-three
                  and one-third percent (33-1/3%) of the Fair Market Value per
                  share of Common Stock on the option grant date.

                        2. The exercise price shall become immediately due upon
                  exercise of the option and shall be payable in one or more of
                  the alternative forms authorized under the Discretionary
                  Option Grant Program. Except to the extent the sale and
                  remittance procedure specified thereunder is utilized, payment
                  of the exercise price for the purchased shares must be made on
                  the Exercise Date.

                  B. NUMBER OF OPTION SHARES. The number of shares of Common
Stock subject to the option shall be determined pursuant to the following
formula (rounded down to the nearest whole number):

                        X = A / (B x 66-2/3%), where

                        X is the number of option shares,

                        A is the dollar amount of the approved reduction in the
                  Optionee's base salary for the calendar year, and


                                       10
<PAGE>

                        B is the Fair Market Value per share of Common Stock on
                  the option grant date.

                  C. EXERCISE AND TERM OF OPTIONS. The option shall become
exercisable in a series of twelve (12) successive equal monthly installments
upon the Optionee's completion of each calendar month of Service in the calendar
year for which the salary reduction is in effect. Each option shall have a
maximum term of ten (10) years measured from the option grant date.

                  D. CESSATION OF SERVICE. Each option outstanding at the time
of the Optionee's cessation of Service shall remain exercisable, for any or all
of the shares for which the option is exercisable at the time of such cessation
of Service, until the EARLIER of (i) the expiration of the option term or (ii)
the expiration of the three (3)-year period following the Optionee's cessation
of Service. To the extent the option is held by the Optionee at the time of his
or her death, the option may be exercised by his or her Beneficiary. However,
the option shall, immediately upon the Optionee's cessation of Service,
terminate and cease to remain outstanding with respect to any and all shares of
Common Stock for which the option is not otherwise at that time exercisable.

            III.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

                  A. In the event of any Change in Control or Hostile Take-Over
while the Optionee remains in Service, each outstanding option shall
automatically accelerate so that each such option shall, immediately prior to
the effective date of the Change in Control or Hostile Take-Over, become fully
exercisable with respect to the total number of shares of Common Stock at the
time subject to such option and may be exercised for any or all of those shares
as fully-vested shares of Common Stock. Each such option accelerated in
connection with a Change in Control shall terminate upon the Change in Control,
except to the extent assumed by the successor corporation (or parent thereof) or
otherwise continued in full force and effect pursuant to the terms of the Change
in Control. Each such option accelerated in connection with a Hostile Take-Over
shall remain exercisable until the expiration or sooner termination of the
option term.

                  B. Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted to apply to the number and class of
securities which would have been issuable to the Optionee in consummation of
such Change in Control had the option been exercised immediately prior to such
Change in Control. Appropriate adjustments shall also be made to the exercise
price payable per share under each outstanding option, PROVIDED the aggregate
exercise price payable for such securities shall remain the same.

                  C. Upon the occurrence of a Hostile Take-Over, the Optionee
shall have a thirty (30)-day period in which to surrender to the Corporation
each of his or her outstanding options. The Optionee shall in return be entitled
to a cash distribution from the Corporation in an amount equal to the excess of
(i) the Option Surrender Value of the shares of Common Stock at the time subject
to each surrendered option (whether or not the Optionee is otherwise at the time
vested in those shares) over (ii) the aggregate exercise price payable for such
shares. Such cash distribution shall be paid within five (5) days following the
surrender of the option to the Corporation.

            IV.   REMAINING TERMS

                  The remaining terms of each option granted under the Salary
Investment Option Grant Program shall be the same as the terms in effect for
options made under the Discretionary Option Grant Program.

                             STOCK ISSUANCE PROGRAM

            I.    STOCK ISSUANCE TERMS

                  Shares of Common Stock may be issued under the Stock Issuance
Program through direct and immediate issuances without any intervening options.
Shares of Common Stock may also be issued under the Stock Issuance Program
pursuant to share right awards which entitle the recipients to receive those
shares upon the attainment of designated performance goals or Service
requirements. Each such award shall be evidenced by one or more documents which
comply with the terms specified below.

                  A. PURCHASE PRICE.

                        1. The purchase price per share of Common Stock subject
                  to direct issuance shall be fixed by the Plan Administrator,
                  but shall not be less than one hundred percent (100%) of the
                  Fair Market Value per share of Common Stock on the issuance
                  date.

                        2. Subject to the provisions of Section II of Article
                  Seven, shares of Common Stock may be issued under the Stock
                  Issuance Program for any of the following items of
                  consideration which the Plan Administrator may deem
                  appropriate in each individual instance:

                              (i) cash or check made payable to the Corporation,
                        or

                              (ii) past services rendered to the Corporation (or
                        any Parent or Subsidiary).

                  B. VESTING/ISSUANCE PROVISIONS.

                        1. The Plan Administrator may issue shares of Common
                  Stock which are fully and immediately vested upon issuance or
                  which are to vest in one or more installments over the
                  Participant's period of Service or upon attainment of
                  specified performance objectives. Alternatively, the Plan
                  Administrator may issue share right awards which shall entitle
                  the recipient to receive a specified number of vested shares
                  of Common Stock upon the attainment of one or more performance
                  goals or Service requirements established by the Plan
                  Administrator.

                        2. Any new, substituted or additional securities or
                  other property (including money paid other than as a regular
                  cash dividend) which the Participant may have the right to
                  receive with respect to his or her unvested shares of Common
                  Stock by reason of any stock dividend, stock split,
                  recapitalization, combination of shares, exchange of shares or
                  other change affecting the outstanding Common Stock as a class
                  without the Corporation's receipt of consideration shall be
                  issued subject to (i) the same vesting requirements applicable
                  to the Participant's unvested shares of Common Stock and (ii)
                  such escrow arrangements as the Plan Administrator shall deem
                  appropriate.

                        3. The Participant shall have full stockholder rights
                  with respect to the issued shares of Common Stock, whether or
                  not the Participant's interest in those shares is


                                       13
<PAGE>

                  vested. Accordingly, the Participant shall have the right to
                  vote such shares and to receive any regular cash dividends
                  paid on such shares.

                        4. Should the Participant cease to remain in Service
                  while holding one or more unvested shares of Common Stock, or
                  should the performance objectives not be attained with respect
                  to one or more such unvested shares of Common Stock, then
                  those shares shall be immediately surrendered to the
                  Corporation for cancellation, and the Participant shall have
                  no further stockholder rights with respect to those shares. To
                  the extent the surrendered shares were previously issued to
                  the Participant for consideration paid in cash or cash
                  equivalent (including the Participant's purchase-money
                  indebtedness), the Corporation shall repay to the Participant
                  the cash consideration paid for the surrendered shares and
                  shall cancel the unpaid principal balance of any outstanding
                  purchase-money note of the Participant attributable to the
                  surrendered shares.

                        5. The Plan Administrator may waive the surrender and
                  cancellation of one or more unvested shares of Common Stock
                  (or other assets attributable thereto) which would otherwise
                  occur upon the cessation of the Participant's Service or the
                  non-attainment of the performance objectives applicable to
                  those shares. Such waiver shall result in the immediate
                  vesting of the Participant's interest in the shares of Common
                  Stock as to which the waiver applies. Such waiver may be
                  effected at any time, whether before or after the
                  Participant's cessation of Service or the attainment or
                  non-attainment of the applicable performance objectives.

                        6. Outstanding share right awards shall automatically
                  terminate, and no shares of Common Stock shall actually be
                  issued in satisfaction of those awards, if the performance
                  goals or Service requirements established for such awards are
                  not attained. The Plan Administrator, however, shall have the
                  authority to issue shares of Common Stock in satisfaction of
                  one or more outstanding share right awards as to which the
                  designated performance goals or Service requirements are not
                  attained.

            II.   CHANGE IN CONTROL/HOSTILE TAKE-OVER

                  A. All of the Corporation's outstanding repurchase rights
shall terminate automatically, and all the shares of Common Stock subject to
those terminated rights shall immediately vest in full, in the event of any
Change in Control, except to the extent (i) those repurchase rights are assigned
to the successor corporation (or parent thereof) or otherwise continue in full
force and effect pursuant to the terms of the Change in Control or (ii) such
accelerated vesting is precluded by other limitations imposed by the Plan
Administrator at the time the repurchase right is issued.

                  B. The Plan Administrator may at any time provide for the
automatic termination of one or more of those outstanding repurchase rights and
the immediate vesting of the shares of Common Stock subject to those terminated
rights upon (i) a Change in Control or Hostile Take-Over or (ii) an Involuntary
Termination of the Participant's Service within a designated period (not to
exceed eighteen (18) months) following the effective date of any Change in
Control or Hostile Take-Over in which those repurchase rights are assigned to
the successor corporation (or parent thereof) or otherwise continue in full
force and effect.

            III.  SHARE ESCROW/LEGENDS

                  Unvested shares may, in the Plan Administrator's discretion,
be held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing those unvested shares.

                         AUTOMATIC OPTION GRANT PROGRAM

            I.    OPTION TERMS

                  A. GRANT DATES. Options shall be made on the dates specified
below:

                        1. Each individual who is first elected or appointed as
                  a non-employee Board member at any time after the Underwriting
                  Date shall automatically be granted, on the date of such
                  initial election or appointment, a Non-Statutory Option to
                  purchase [twenty thousand (20,000)] shares of Common Stock,
                  provided that individual has not previously been in the employ
                  of the Corporation (or any Parent or Subsidiary).

                        2. On the date of each Annual Stockholders Meeting held
                  after the Underwriting Date, each individual who is to
                  continue to serve as a non-employee Board member, whether or
                  not that individual is standing for re-election to the Board,
                  shall automatically be granted a Non-Statutory Option to
                  purchase [five thousand (5,000)] shares of Common Stock,
                  provided such individual has served as a non-employee Board
                  member for at least six (6) months.

                  B. EXERCISE PRICE.

                        1. The exercise price per share shall be equal to one
                  hundred percent (100%) of the Fair Market Value per share of
                  Common Stock on the option grant date.

                        2. The exercise price shall be payable in one or more of
                  the alternative forms authorized under the Discretionary
                  Option Grant Program. Except to the extent the sale and
                  remittance procedure specified thereunder is utilized, payment
                  of the exercise price for the purchased shares must be made on
                  the Exercise Date.

                  C. OPTION TERM. Each option shall have a term of ten (10)
years measured from the option grant date.

                  D. EXERCISE AND VESTING OF OPTIONS. Each option shall be
immediately exercisable for any or all of the option shares. However, any shares
purchased under the option shall be subject to repurchase by the Corporation, at
the exercise price paid per share, upon the Optionee's cessation of Board
service prior to vesting in those shares. Each initial 20,000 share grant shall
vest, and the Corporation's repurchase right shall lapse, in a series of four
(4) successive equal annual installments over the Optionee's period of continued
service as a Board member, with the first such installment to vest upon the
Optionee's completion of one (1) year of Board service measured from the option
grant date. Each annual 5,000 share option grant shall vest, and the
Corporation's repurchase right shall lapse upon the Optionee's completion of one
(1) year of Board service measured from the option grant date.

                  E. CESSATION OF BOARD SERVICE. The following provisions shall
govern the exercise of any options outstanding at the time of the Optionee's
cessation of Board service:


                                       16
<PAGE>

                        (i) Any option outstanding at the time of the Optionee's
                  cessation of Board service for any reason shall remain
                  exercisable for a twelve (12)-month period following the date
                  of such cessation of Board service, but in no event shall such
                  option be exercisable after the expiration of the option term.

                        (ii) Any option exercisable in whole or in part by the
                  Optionee at the time of death may be subsequently exercised by
                  his or her Beneficiary.

                        (iii) Following the Optionee's cessation of Board
                  service, the option may not be exercised in the aggregate for
                  more than the number of shares for which the option was
                  exercisable on the date of such cessation of Board service.
                  Upon the expiration of the applicable exercise period or (if
                  earlier) upon the expiration of the option term, the option
                  shall terminate and cease to be outstanding for any vested
                  shares for which the option has not been exercised. However,
                  the option shall, immediately upon the Optionee's cessation of
                  Board service, terminate and cease to be outstanding for any
                  and all shares for which the option is not otherwise at that
                  time exercisable.

                        (iv) However, should the Optionee cease to serve as a
                  Board member by reason of death or Permanent Disability, then
                  all shares at the time subject to the option shall immediately
                  vest so that such option may, during the twelve (12)-month
                  exercise period following such cessation of Board service, be
                  exercised for all or any portion of those shares as
                  fully-vested shares of Common Stock.

            II.   CHANGE IN CONTROL/HOSTILE TAKE-OVER

                  A. In the event of any Change in Control or Hostile Take-Over,
the shares of Common Stock at the time subject to each outstanding option but
not otherwise vested shall automatically vest in full so that each such option
may, immediately prior to the effective date of such Change in Control or
Hostile Take-Over, became fully exercisable for all of the shares of Common
Stock at the time subject to such option and maybe exercised for all or any of
those shares as fully-vested shares of Common Stock. Each such option
accelerated in connection with a Change in Control shall terminate upon the
Change in Control, except to the extent assumed by the successor corporation (or
parent thereof) or otherwise continued in full force and effect pursuant to the
terms of the Change in Control. Each such option accelerated in connection with
a Hostile Take-Over shall remain exercisable until the expiration or sooner
termination of the option term.

                  B. All outstanding repurchase rights shall automatically
terminate and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Change in Control or Hostile
Take-Over.

                  C. Upon the occurrence of a Hostile Take-Over, the Optionee
shall have a thirty (30)-day period in which to surrender to the Corporation
each of his or her outstanding


                                       17
<PAGE>

options. The Optionee shall in return be entitled to a cash distribution from
the Corporation in an amount equal to the excess of (i) the Option Surrender
Value of the shares of Common Stock at the time subject to each surrendered
option (whether or not the option is otherwise at the time exercisable for those
shares) over (ii) the aggregate exercise price payable for such shares. Such
cash distribution shall be paid within five (5) days following the surrender of
the option to the Corporation.

                  D. Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted to apply to the number and class of
securities which would have been issuable to the Optionee in consummation of
such Change in Control had the option been exercised immediately prior to such
Change in Control. Appropriate adjustments shall also be made to the exercise
price payable per share under each outstanding option, PROVIDED the aggregate
exercise price payable for such securities shall remain the same.

            III.  REMAINING TERMS

                  The remaining terms of each option granted under the Automatic
Option Grant Program shall be the same as the terms in effect for options made
under the Discretionary Option Grant Program.

                        DIRECTOR FEE OPTION GRANT PROGRAM

            I.    OPTION GRANTS

                  The Board may implement the Director Fee Option Grant Program
as of the first day of any calendar year beginning after the Underwriting Date.
Upon such implementation of the Program, each non-employee Board member may
elect to apply all or any portion of the annual retainer fee otherwise payable
in cash for his or her service on the Board to the acquisition of a special
option grant under this Director Fee Option Grant Program. Such election must be
filed with the Corporation's Chief Financial Officer prior to the first day of
the calendar year for which the election is to be in effect. Each non-employee
Board member who files such a timely election with respect to the annul retainer
fee shall automatically be granted an option under this Director Fee Option
Grant Program on the first trading day in January in the calendar year for which
that fee would otherwise be payable.

            II.   OPTION TERMS

                  Each option shall be a Non-Statutory Option governed by the
terms and conditions specified below.

                  A. EXERCISE PRICE.

                        1. The exercise price per share shall be thirty-three
                  and one-third percent (33-1/3%) of the Fair Market Value per
                  share of Common Stock on the option grant date.

                        2. The exercise price shall become immediately due upon
                  exercise of the option and shall be payable in one or more of
                  the alternative forms authorized under the Discretionary
                  Option Grant Program. Except to the extent the sale and
                  remittance procedure specified thereunder is utilized, payment
                  of the exercise price for the purchased shares must be made on
                  the Exercise Date.

                  B. NUMBER OF OPTION SHARES. The number of shares of Common
Stock subject to the option shall be determined pursuant to the following
formula (rounded down to the nearest whole number):

                  X = A / (B x 66-2/3%), where

                  X is the number of option shares,

                  A is the portion of the annual retainer fee subject to the
                  non-employee Board member's election, and

                  B is the Fair Market Value per share of Common Stock on the
                  option grant date.


                                       19
<PAGE>

                  C. EXERCISE AND TERM OF OPTIONS. The option shall become
exercisable in a series of twelve (12) successive equal monthly installments
upon the Optionee's completion of each month of Board service during the
calendar year in which the option is granted. Each option shall have a maximum
term of ten (10) years measured from the option grant date.

                  D. CESSATION OF BOARD SERVICE. Should the Optionee cease Board
service for any reason (other than death or Permanent Disability) while holding
one or more options, then each such option shall remain exercisable, for any or
all of the shares for which the option is exercisable at the time of such
cessation of Board service, until the EARLIER of (i) the expiration of the ten
(10)-year option term or (ii) the expiration of the three (3)-year period
measured from the date of such cessation of Board service. However, each option
held by the Optionee at the time of such cessation of Board service shall
immediately terminate and cease to remain outstanding with respect to any and
all shares of Common Stock for which the option is not otherwise at that time
exercisable.

                  E. DEATH OR PERMANENT DISABILITY. Should the Optionee's
service as a Board member cease by reason of death or Permanent Disability, then
each option held by such Optionee shall immediately become exercisable for all
the shares of Common Stock at the time subject to that option, and the option
may be exercised for any or all of those shares as fully-vested shares until the
EARLIER of (i) the expiration of the ten (10)-year option term or (ii) the
expiration of the three (3)-year period measured from the date of such cessation
of Board service.

                  Should the Optionee die after cessation of Board service but
while holding one or more options, then each such option may be exercised, for
any or all of the shares for which the option is exercisable at the time of the
Optionee's cessation of Board service (less any shares subsequently purchased by
Optionee prior to death), by the Optionee's Beneficiary. Such right of exercise
shall lapse, and the option shall terminate, upon the EARLIER of (i) the
expiration of the ten (10)-year option term or (ii) the three (3)-year period
measured from the date of the Optionee's cessation of Board service.

            III.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

                  A. In the event of any Change in Control or Hostile Take-Over
while the Optionee remains in Board service, each outstanding option held by
such Optionee shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Change in Control or Hostile
Take-Over, become fully exercisable with respect to the total number of shares
of Common Stock at the time subject to such option and may be exercised for any
or all of those shares as fully-vested shares of Common Stock. Each such option
accelerated in connection with a Change in Control shall terminate upon the
Change in Control, except to the extent assumed by the successor corporation (or
parent thereof) or otherwise expressly continued in full force and effect
pursuant to the terms of the Change in Control. Each such option accelerated in
connection with a Hostile Take-Over shall remain exercisable until the
expiration or sooner termination of the option term.

                  B. Upon the occurrence of a Hostile Take-Over, the Optionee
shall have a thirty (30)-day period in which to surrender to the Corporation
each of his or her outstanding options. The Optionee shall in return be entitled
to a cash distribution from the Corporation in an


                                       20
<PAGE>

amount equal to the excess of (i) the Option Surrender Value of the shares of
Common Stock at the time subject to each surrendered option (whether or not the
Optionee is otherwise at the time vested in those shares) over (ii) the
aggregate exercise price payable for such shares. Such cash distribution shall
be paid within five (5) days following the surrender of the option to the
Corporation.

            IV.   REMAINING TERMS

                  The remaining terms of each option granted under this Director
Fee Option Grant Program shall be the same as the terms in effect for options
made under the Discretionary Option Grant Program.

                                  MISCELLANEOUS

            I.    NO IMPAIRMENT OF AUTHORITY

                  Outstanding awards shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

            II.   FINANCING

                  The Plan Administrator may permit any Optionee or Participant
to pay the option exercise price under the Discretionary Option Grant Program or
the purchase price of shares issued under the Stock Issuance Program by
delivering a full-recourse, interest bearing promissory note payable in one or
more installments. The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion. In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

            III.  TAX WITHHOLDING

                  A. The Corporation's obligation to deliver shares of Common
Stock upon the exercise of options or the issuance or vesting of such shares
under the Plan shall be subject to the satisfaction of all applicable Federal,
state and local income and employment tax withholding requirements.

                  B. The Plan Administrator may, in its discretion, provide any
or all holders of Non-Statutory Options or unvested shares of Common Stock under
the Plan with the right to use shares of Common Stock in satisfaction of all or
part of the Withholding Taxes incurred by such holders in connection with the
exercise of their options or the vesting of their shares. Such right may be
provided to any such holder in either or both of the following formats:

                  STOCK WITHHOLDING: The election to have the Corporation
            withhold, from the shares of Common Stock otherwise issuable upon
            the exercise of such Non-Statutory Option or the vesting of such
            shares, a portion of those shares with an aggregate Fair Market
            Value equal to the percentage of the Withholding Taxes (not to
            exceed one hundred percent (100%) designated by the holder.

                  STOCK DELIVERY: The election to deliver to the Corporation, at
            the time the Non-Statutory Option is exercised or the shares vest,
            one or more shares of Common Stock previously acquired by such
            holder (other than in connection with the option exercise or share
            vesting triggering the Withholding Taxes) with an aggregate Fair
            Market Value equal to the percentage of the Taxes (not to exceed one
            hundred percent (100%)) designated by the holder.

<PAGE>

            IV.   EFFECTIVE DATE AND TERM OF THE PLAN

                  A. The Plan shall become effective immediately upon the Plan
Effective Date. However, the Salary Investment Option Grant and Director Fee
Option Grant Programs shall not be implemented until such time as the Primary
Committee or the Board may deem appropriate. Options may be granted under the
Discretionary Option Grant Program at any time on or after the Plan Effective
Date. However, no options granted under the Plan may be exercised, and no shares
shall be issued under the Plan, until the Plan is approved by the Corporation's
stockholders. If such stockholder approval is not obtained within twelve (12)
months after the Plan Effective Date, then all options previously granted under
this Plan shall terminate and cease to be outstanding, and no further options
shall be granted and no shares shall be issued under the Plan.

                  B. The Plan shall serve as the successor to the Predecessor
Plan, and no further options or direct stock issuances shall be made under the
Predecessor Plan after the Plan Effective Date. All options outstanding under
the Predecessor Plan on the Plan Effective Date shall be incorporated into the
Plan at that time and shall be treated as outstanding options under the Plan.
However, each outstanding option so incorporated shall continue to be governed
solely by the terms of the documents evidencing such option, and no provision of
the Plan shall be deemed to affect or otherwise modify the rights or obligations
of the holders of such incorporated options with respect to their acquisition of
shares of Common Stock.

                  C. One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Changes in Control, may, in the Plan Administrator's discretion, be extended
to one or more options incorporated from the Predecessor Plan which do not
otherwise contain such provisions.

                  D. The Plan shall terminate upon the EARLIEST of (i) January
1, 2010, (ii) the date on which all shares available for issuance under the Plan
shall have been issued as fully-vested shares or (iii) the termination of all
outstanding options in connection with a Change in Control. Upon such plan
termination, all outstanding options and unvested stock issuances shall
thereafter continue to have force and effect in accordance with the provisions
of the documents evidencing such grants or issuances.

            V.    AMENDMENT OF THE PLAN

                  A. The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects. However, no such
amendment or modification shall adversely affect the rights and obligations with
respect to stock options or unvested stock issuances at the time outstanding
under the Plan unless the Optionee or the Participant consents to such amendment
or modification. In addition, certain amendments may require stockholder
approval pursuant to applicable laws or regulations.

                  B. Options to purchase shares of Common Stock may be granted
under the Discretionary Option Grant and Salary Investment Option Grant Programs
and shares of Common Stock may be issued under the Stock Issuance Program that
are in each instance in excess of the number of shares then available for
issuance under the Plan, provided any excess


                                       23
<PAGE>

shares actually issued under those programs shall be held in escrow until there
is obtained stockholder approval of an amendment sufficiently increasing the
number of shares of Common Stock available for issuance under the Plan. If such
stockholder approval is not obtained within twelve (12) months after the date
the first such excess issuances are made, then (i) any unexercised options
granted on the basis of such excess shares shall terminate and cease to be
outstanding and (ii) the Corporation shall promptly refund to the Optionees and
the Participants the exercise or purchase price paid for any excess shares
issued under the Plan and held in escrow, together with interest (at the
applicable Short Term Federal Rate) for the period the shares were held in
escrow, and such shares shall thereupon be automatically cancelled and cease to
be outstanding.

            VI.   USE OF PROCEEDS

                  Any cash proceeds received by the Corporation from the sale of
shares of Common Stock under the Plan shall be used for general corporate
purposes.

            VII.  REGULATORY APPROVALS

                  A. The implementation of the Plan, the granting of any stock
option under the Plan and the issuance of any shares of Common Stock (i) upon
the exercise of any granted option or (ii) under the Stock Issuance Program
shall be subject to the Corporation's procurement of all approvals and permits
required by regulatory authorities having jurisdiction over the Plan, the stock
options granted under it and the shares of Common Stock issued pursuant to it.

                  B. No shares of Common Stock or other assets shall be issued
or delivered under the Plan unless and until there shall have been compliance
with all applicable requirements of Federal and state securities laws, including
the filing and effectiveness of the Form S-8 registration statement for the
shares of Common Stock issuable under the Plan, and all applicable listing
requirements of any stock exchange (or the Nasdaq National Market, if
applicable) on which Common Stock is then listed for trading.

            VIII. NO EMPLOYMENT/SERVICE RIGHTS

                  Nothing in the Plan shall confer upon the Optionee or the
Participant any right to continue in Service for any period of specific duration
or interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

                        (i) If the Common Stock is at the time traded on the

                  the closing selling price per share of Common Stock on the

                  selling price on the last preceding date for which such
                  quotation exists.

                  as such price is officially quoted in the composite tape of
                  transactions on such exchange. If there is no closing selling
                  price for the Common Stock on the date in question, then the

                        2000 EMPLOYEE STOCK PURCHASE PLAN

            I.    PURPOSE OF THE PLAN

                  This 2000 Employee Stock Purchase Plan is intended to promote
the interests of Wireless, Inc., a Delaware corporation, by providing eligible
employees with the opportunity to acquire a proprietary interest in the
Corporation through participation in a payroll-deduction based employee stock
purchase plan designed to qualify under Section 423 of the Code.

                  Capitalized terms herein shall have the meanings assigned to
such terms in the attached Appendix.

            II.   ADMINISTRATION OF THE PLAN

                  The Plan Administrator shall have full authority to interpret
and construe any provision of the Plan and to adopt such rules and regulations
for administering the Plan as it may deem necessary in order to comply with the
requirements of Section 423 of the Code. Decisions of the Plan Administrator
shall be final and binding on all parties having an interest in the Plan.

            III.  STOCK SUBJECT TO PLAN

                  A. The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market. The maximum number of shares of Common Stock
which may be issued over the term of the Plan shall not exceed 3,000,000 shares.

                  B. The number of shares of Common Stock available for issuance
under the Plan shall automatically increase on the first trading day of January
each year during the term of the Plan, beginning January 1, 2001, by an amount
equal to two percent (2%) of the total number of shares of Common Stock
outstanding on the last trading day of the immediately preceding calendar year,
but in no event shall any such annual increase exceed 1,300,000 shares.

                  C. Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and class of securities
issuable under the Plan, (ii) the maximum number and class of securities
purchasable per Participant and in the aggregate on any one Purchase Date and
(iii) the number and class of securities and the price per share in effect under
each outstanding purchase right in order to prevent the dilution or enlargement
of benefits thereunder.


<PAGE>

            IV.   OFFERING PERIODS

                  A. Shares of Common Stock shall be offered for purchase under
the Plan through a series of successive offering periods until such time as (i)
the maximum number of shares of Common Stock available for issuance under the
Plan shall have been purchased or (ii) the Plan shall have been sooner
terminated.

                  B. Each offering period shall be of such duration (not to
exceed twenty-four (24) months) as determined by the Plan Administrator prior to
the start date of such offering period. However, the initial offering period
shall commence at the Effective Time and terminate on the last business day in
April 2002. Subsequent offering periods shall commence as designated by the
Plan Administrator.

                  C. Each offering period shall be comprised of a series of one
or more successive Purchase Intervals. Purchase Intervals shall run from the
first business day in May each year to the last business day in October of the
same year and from the first business day in November each year to the last
business day in April of the following year. However, the first Purchase
Interval in effect under the initial offering period shall commence at the
Effective Time and terminate on the last business day in October 2000.

                  D. Should the Fair Market Value per share of Common Stock on
any Purchase Date within an offering period be less than the Fair Market Value
per share of Common Stock on the start date of that offering period, then that
offering period shall automatically terminate immediately after the purchase of
shares of Common Stock on such Purchase Date, and a new offering period shall
commence on the next business day following such Purchase Date. The new offering
period shall have a duration of twenty (24) months, unless a shorter duration is
established by the Plan Administrator within five (5) business days following
the start date of that offering period.

            V.    ELIGIBILITY

                  A. Each individual who is an Eligible Employee on the start
date of an offering period under the Plan may enter that offering period on such
start date or on any subsequent Semi-Annual Entry Date within that offering
period, provided he or she remains an Eligible Employee.

                  B. Each individual who first becomes an Eligible Employee
after the start date of an offering period may enter that offering period on any
subsequent Semi-Annual Entry Date within that offering period on which he or she
is an Eligible Employee.

                  C. The date an individual enters an offering period shall be
designated his or her Entry Date for purposes of that offering period.

                  D. To participate in the Plan for a particular offering

                                       2
<PAGE>

stock purchase agreement and a payroll deduction authorization) and file such
forms with the Plan Administrator (or its designate) on or before his or her
scheduled Entry Date.

            VI.   PAYROLL DEDUCTIONS

                  A. The payroll deduction authorized by the Participant for
purposes of acquiring shares of Common Stock during an offering period may be
any multiple of one percent (1%) of the Cash Earnings paid to the Participant
during each Purchase Interval within that offering period, up to a maximum of
ten percent (10%). The deduction rate so authorized shall continue in effect
throughout the offering period, except to the extent such rate is changed in
accordance with the following guidelines:

                        (i) The Participant may, at any time during the offering
                  period, reduce his or her rate of payroll deduction to become
                  effective as soon as possible after filing the appropriate
                  form with the Plan Administrator. The Participant may not,
                  however, effect more than one (1) such reduction per Purchase
                  Interval.

                        (ii) The Participant may, prior to the commencement of
                  any new Purchase Interval within the offering period, increase
                  the rate of his or her payroll deduction by filing the
                  appropriate form with the Plan Administrator. The new rate
                  (which may not exceed the ten percent (10%) maximum) shall
                  become effective on the start date of the first Purchase
                  Interval following the filing of such form.

                  B. Payroll deductions shall begin on the first pay day
following the Participant's Entry Date into the offering period and shall
(unless sooner terminated by the Participant) continue through the pay day
ending with or immediately prior to the last day of that offering period. The
amounts so collected shall be credited to the Participant's book account under
the Plan, but no interest shall be paid on the balance from time to time
outstanding in such account. The amounts collected from the Participant shall
not be required to be held in any segregated account or trust fund and may be
commingled with the general assets of the Corporation and used for general
corporate purposes.

                  C. Payroll deductions shall automatically cease upon the
termination of the Participant's purchase right in accordance with the
provisions of the Plan.

                  D. The Participant's acquisition of Common Stock under the
Plan on any Purchase Date shall neither limit nor require the Participant's
acquisition of Common Stock on any subsequent Purchase Date, whether within the
same or a different offering period.

            VII.  PURCHASE RIGHTS

                  A. GRANT OF PURCHASE RIGHT. A Participant shall be granted a
separate purchase right for each offering period in which he or she
participates. The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the Participant with the right
to purchase shares of Common Stock, in a series of successive


                                       3
<PAGE>

installments over the remainder of such offering period, upon the terms set
forth below. The Participant shall execute a stock purchase agreement embodying
such terms and such other provisions (not inconsistent with the Plan) as the
Plan Administrator may deem advisable.

                  Under no circumstances shall purchase rights be granted under
the Plan to any Eligible Employee if such individual would, immediately after
the grant, own (within the meaning of Code Section 424(d)) or hold outstanding
options or other rights to purchase, stock possessing five percent (5%) or more
of the total combined voting power or value of all classes of stock of the
Corporation or any Corporate Affiliate.

                  B. EXERCISE OF THE PURCHASE RIGHT. Each purchase right shall
be automatically exercised in installments on each successive Purchase Date
within the offering period, and shares of Common Stock shall accordingly be
purchased on behalf of each Participant (other than Participants whose payroll
deductions have previously been refunded pursuant to the Termination of Purchase
Right provisions below) on each such Purchase Date. The purchase shall be
effected by applying the Participant's payroll deductions for the Purchase
Interval ending on such Purchase Date to the purchase of whole shares of Common
Stock at the purchase price in effect for the Participant for that Purchase
Date.

                  C. PURCHASE PRICE. The purchase price per share at which
Common Stock will be purchased on the Participant's behalf on each Purchase Date
within the offering period shall be equal to eighty-five percent (85%) of the
LOWER of (i) the Fair Market Value per share of Common Stock on the
Participant's Entry Date into that offering period or (ii) the Fair Market Value
per share of Common Stock on that Purchase Date.

                  D. NUMBER OF PURCHASABLE SHARES. The number of shares of
Common Stock purchasable by a Participant on each Purchase Date during the
offering period shall be the number of whole shares obtained by dividing the
amount collected from the Participant through payroll deductions during the
Purchase Interval ending with that Purchase Date by the purchase price in effect
for the Participant for that Purchase Date. However, the maximum number of
shares of Common Stock purchasable per Participant on any one Purchase Date
shall not exceed 800 shares, subject to periodic adjustments in the event of
certain changes in the Corporation's capitalization. In addition, the maximum
number of shares of Common Stock purchasable in the aggregate by all
Participants on any one Purchase Date shall not exceed 150,000 shares, subject
to periodic adjustments in the event of certain changes in the corporation's
capitalization.

                  E. EXCESS PAYROLL DEDUCTIONS. Any payroll deductions not
applied to the purchase of shares of Common Stock on any Purchase Date because
they are not sufficient to purchase a whole share of Common Stock shall be held
for the purchase of Common Stock on the next Purchase Date. However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable on the Purchase Date
shall be promptly refunded.

                  F. TERMINATION OF PURCHASE RIGHT. The following provisions
shall govern the termination of outstanding purchase rights:

                        (i) A Participant may, at any time prior to the next
                  scheduled Purchase Date in the offering period, terminate his
                  or her outstanding purchase right by filing the appropriate
                  form with the Plan Administrator (or its designate), and no
                  further payroll deductions shall be collected from the
                  Participant with respect to the terminated purchase right. Any
                  payroll deductions collected during the Purchase Interval in
                  which such termination occurs shall, at the Participant's
                  election, be immediately refunded or held for the purchase of
                  shares on the next Purchase Date. If no such election is made
                  at the time such purchase right is terminated, then the
                  payroll deductions collected with respect to the terminated
                  right shall be refunded as soon as possible.

                        (ii) The termination of such purchase right shall be
                  irrevocable, and the Participant may not subsequently rejoin
                  the Plan during the Purchase Interval in which the purchase
                  right was terminated. In order to resume participation in any
                  subsequent Purchase Interval, such individual must re-enroll
                  in the Plan (by making a timely filing of the prescribed
                  enrollment forms) on or before his or her scheduled Entry
                  Date.

                        (iii) Should the Participant cease to remain an Eligible
                  Employee for any reason (including death, disability or change
                  in status) while his or her purchase right remains
                  outstanding, then that purchase right shall immediately
                  terminate, and all of the Participant's payroll deductions for
                  the Purchase Interval in which the purchase right so
                  terminates shall be immediately refunded. However, should the
                  Participant cease to remain in active service by reason of an
                  approved unpaid leave of absence, then the Participant shall
                  have the right, exercisable up until the last business day of
                  the Purchase Interval in which such leave commences, to (a)
                  withdraw all the payroll deductions collected to date on his
                  or her behalf for that Purchase Interval or (b) have such
                  funds held for the purchase of shares on his or her behalf on
                  the next scheduled Purchase Date. In no event, however, shall
                  any further payroll deductions be collected on the
                  Participant's behalf during such leave. Upon the Participant's
                  return to active service (x) within ninety (90) days following
                  the commencement of such leave or (y) prior to the expiration
                  of any longer period for which such Participant's right to
                  reemployment with the Corporation is guaranteed by statute or
                  contract, his or her payroll deductions under the Plan shall
                  automatically resume at the rate in effect at the time the
                  leave began, unless the Participant withdraws from the Plan
                  prior to his or her return. An individual who returns to
                  active employment following a leave of absence which exceeds
                  in duration the applicable (x) or (y) time period will be
                  treated as a new Employee for purposes of subsequent
                  participation in the Plan and must accordingly re-enroll in
                  the Plan (by making a timely filing of the prescribed
                  enrollment forms) on or before his or her scheduled Entry Date
                  into the offering period.

                  G. CORPORATE TRANSACTION. Each outstanding purchase right
shall automatically be exercised, immediately prior to the effective date of any
Corporate Transaction, by applying the payroll deductions of each Participant
for the Purchase Interval in which such Corporate Transaction occurs to the
purchase of whole shares of Common Stock at a purchase price per share equal to
eighty-five percent (85%) of the LOWER of (i) the Fair Market Value per share of
Common Stock on the Participant's Entry Date into the offering period in which
such Corporate Transaction occurs or (ii) the Fair Market Value per share of
Common Stock immediately prior to the effective date of such Corporate
Transaction. However, the applicable limitations on the number of shares of
Common Stock purchasable per Participant and in the aggregate shall continue to
apply to any such purchase.

                  The Corporation shall use its best efforts to provide at least
ten (10)-days prior written notice of the occurrence of any Corporate
Transaction, and Participants shall, following the receipt of such notice, have
the right to terminate their outstanding purchase rights prior to the effective
date of the Corporate Transaction.

                  H. PRORATION OF PURCHASE RIGHTS. Should the total number of
shares of Common Stock to be purchased pursuant to outstanding purchase rights
on any particular date exceed the number of shares then available for issuance
under the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

                  I. ASSIGNABILITY. The purchase right shall be exercisable only
by the Participant and shall not be assignable or transferable by the
Participant.

                  J. STOCKHOLDER RIGHTS. A Participant shall have no stockholder
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

            VIII. ACCRUAL LIMITATIONS

                  A. No Participant shall be entitled to accrue rights to
acquire Common Stock pursuant to any purchase right outstanding under this Plan
if and to the extent such accrual, when aggregated with (i) rights to purchase
Common Stock accrued under any other purchase right granted under this Plan and
(ii) similar rights accrued under other employee stock purchase plans (within
the meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

                  B. For purposes of applying such accrual limitations to the
purchase rights granted under the Plan, the following provisions shall be in
effect:


                                       6
<PAGE>

                        (i) The right to acquire Common Stock under each
                  outstanding purchase right shall accrue in a series of
                  installments on each successive Purchase Date during the
                  offering period on which such right remains outstanding.

                        (ii) No right to acquire Common Stock under any
                  outstanding purchase right shall accrue to the extent the
                  Participant has already accrued in the same calendar year the
                  right to acquire Common Stock under one (1) or more other
                  purchase rights at a rate equal to Twenty-Five Thousand
                  Dollars ($25,000) worth of Common Stock (determined on the
                  basis of the Fair Market Value per share on the date or dates
                  of grant) for each calendar year such rights were at any time
                  outstanding.

                  C. If by reason of such accrual limitations, any purchase
right of a Participant does not accrue for a particular Purchase Interval, then
the payroll deductions which the Participant made during that Purchase Interval
with respect to such purchase right shall be promptly refunded.

                  D. In the event there is any conflict between the provisions
of this Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

            IX.   EFFECTIVE DATE AND TERM OF THE PLAN

                  A. The Plan was adopted by the Board on January __, 2000 and
shall become effective at the Effective Time, PROVIDED no purchase rights
granted under the Plan shall be exercised, and no shares of Common Stock shall
be issued hereunder, until (i) the Plan shall have been approved by the
stockholders of the Corporation and (ii) the Corporation shall have complied
with all applicable requirements of the 1933 Act (including the registration of
the shares of Common Stock issuable under the Plan on a Form S-8 registration
statement filed with the Securities and Exchange Commission), all applicable
listing requirements of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock is listed for trading and all other
applicable requirements established by law or regulation. In the event such
stockholder approval is not obtained, or such compliance is not effected, within
twelve (12) months after the date on which the Plan is adopted by the Board, the
Plan shall terminate and have no further force or effect, and all sums collected
from Participants during the initial offering period hereunder shall be
refunded.

                  B. Unless sooner terminated by the Board, the Plan shall
terminate upon the EARLIEST of (i) the last business day in April 2010, (ii)
the date on which all shares available for issuance under the Plan shall have
been sold pursuant to purchase rights exercised under the Plan or (iii) the date
on which all purchase rights are exercised in connection with a Corporate
Transaction. No further purchase rights shall be granted or exercised, and no
further payroll deductions shall be collected, under the Plan following such
termination.

            X.    AMENDMENT/TERMINATION OF THE PLAN

                  A. The Board may alter, amend, suspend or terminate the Plan
at any time to become effective immediately following the close of any Purchase
Interval. However, the Plan may be amended or terminated immediately upon Board
action, if and to the extent necessary to assure that the Corporation will not
recognize, for financial reporting purposes, any compensation expense in
connection with the shares of Common Stock offered for purchase under the Plan,
should the financial accounting rules applicable to the Plan at the Effective
Time be subsequently revised so as to require the recognition of compensation
expense in the absence of such amendment or termination.

                  B. In no event may the Board effect any of the following
amendments or revisions to the Plan without the approval of the Corporation's
stockholders: (i) increase the number of shares of Common Stock issuable under
the Plan or the maximum number of shares purchasable per Participant on any one
Purchase Date, except for permissible adjustments in the event of certain
changes in the Corporation's capitalization, (ii) alter the purchase price
formula so as to reduce the purchase price payable for the shares of Common
Stock purchasable under the Plan or (iii) modify eligibility requirements for
participation in the Plan.

            XI.   GENERAL PROVISIONS

                  A. Nothing in the Plan shall confer upon the Participant any
right to continue in the employ of the Corporation or any Corporate Affiliate
for any period of specific duration or interfere with or otherwise restrict in
any way the rights of the Corporation (or any Corporate Affiliate employing such
person) or of the Participant, which rights are hereby expressly reserved by
each, to terminate such person's employment at any time for any reason, with or
without cause.

                  B. All costs and expenses incurred in the administration of
the Plan shall be paid by the Corporation; however, each Plan Participant shall
bear all costs and expenses incurred by such individual in the sale or other
disposition of any shares purchased under the Plan.

                  C. The provisions of the Plan shall be governed by the laws of
the State of Colorado without regard to that State's conflict-of-laws rules.

                    jurisdiction in the matter shall determine that such
                    indemnification is not lawful (and, in this respect, both
                    the Company and Indemnitee have been advised that the
                    Securities and Exchange Commission


                                       2
<PAGE>

                    believes that indemnification for liabilities arising under
                    the federal securities laws is against public policy and is,
                    therefore, unenforceable and that claims for indemnification
                    should be submitted to appropriate courts for adjudication);
                    and

                              vii) except to the extent the aggregate of losses
                    to be indemnified thereunder exceeds the sum of (a) such
                    losses for which the Indemnitee is indemnified pursuant to
                    Section 1 hereof and (b) any additional amount paid to the
                    Indemnitee pursuant to any D & O Insurance purchased and
                    maintained by the Company.

                    (b) No indemnity pursuant to Section 1 or 2 hereof shall be
          paid by the Company if the action, suit or proceeding with respect to
          which a claim for indemnity hereunder is made arose from or is based
          upon any of the following:

                              i) Any solicitation of proxies by Indemnitee, or
                    by a group of which he was or became a member consisting of
                    two or more persons that had agreed (whether formally or
                    informally and whether or not in writing) to act together
                    for the purpose of soliciting proxies, in opposition to any
                    solicitation of proxies approved by the Board of Directors.

                              ii) Any activities by Indemnitee that constitute a
                    breach of or default under any agreement between Indemnitee
                    and the Company.

                  4. CONTRIBUTION. If the indemnification provided in Sections 1
and 2 hereof is unavailable by reason of a Court decision described in Section
3(a)(vi) hereof based on grounds other than any of those set forth in paragraphs
(i) through (v) of Section 3 (a) hereof, then in respect of any threatened,
pending or completed action, suit or proceeding in which the Company is jointly
liable with Indemnitee (or would be if joined in such action, suit or
proceeding), the Company shall contribute to the amount of expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred and paid or payable by Indemnitee in such proportion as is
appropriate to reflect (i) the relative benefits received by the Company on the
one hand and Indemnitee on the other hand from the transaction from which such
action, suit or proceeding arose, and (ii) the relative fault of the Company on
the one hand and of Indemnitee on the other in connection with the events which
resulted in such expenses, judgments, fines or settlement amounts, as well as
any other relevant equitable considerations. The relative fault of the Company
on the one hand and of Indemnitee on the other shall be determined by reference
to, among other things, the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent the circumstances resulting in
such expenses, judgments, fines or settlement amounts. The Company agrees that
it would not be just and equitable if contribution pursuant to this Section 4
were determined by pro rata allocation or any other method of allocation which
does not take account of the foregoing equitable considerations.

                  5. NOTIFICATION AND DEFENSE OF CLAIM. Not later than thirty
(30) days after receipt by Indemnitee of notice of the commencement of any
action, suit or proceeding, Indemnitee shall, if a claim in respect thereof is
to be made against the Company under this Agreement, notify the Company of the
commencement thereof; but Indemnitee's omission so to notify the Company will
not relieve the Company from any liability which it may have to


                                       3
<PAGE>

Indemnitee otherwise than under this Agreement. With respect to any such action,
suit or proceeding as to which Indemnitee notifies the Company of the
commencement thereof:

                    (a) The Company will be entitled to participate therein at
          its own expense.

                    (b) Except as otherwise provided below, to the extent that
          it may wish, the Company shall, jointly with any other indemnifying
          party similarly notified, be entitled to assume the defense thereof,
          with counsel reasonably satisfactory to Indemnitee. After notice from
          the Company to Indemnitee of its election to assume the defense
          thereof, the Company will not be liable to Indemnitee under this
          Agreement for any legal or other expenses subsequently incurred by
          Indemnitee in connection with the defense thereof, other than
          reasonable costs of investigation or as otherwise provided below.
          Indemnitee shall have the right to employ its own counsel in such
          action, suit or proceeding, but the fees and expenses of such counsel
          incurred after notice from the Company of the Company's assumption of
          the defense thereof shall be at the expense of Indemnitee unless (i)
          the employment of counsel by Indemnitee has been authorized by the
          Company; (ii) Indemnitee shall have reasonably concluded that there
          may be a conflict of interest between the Company and Indemnitee in
          the conduct of the defense of such action; or (iii) the Company shall
          not in fact have employed counsel to assume the defense of such
          action; in each of which cases the fees and expenses of Indemnitee's
          separate counsel shall be paid by the Company. The Company shall not
          be entitled to assume the defense of any action, suit or proceeding
          brought by or on behalf of the Company or as to which Indemnitee shall
          have made the conclusion provided for in (ii) above.

                    (c) The Company shall not be liable to indemnify Indemnitee
          under this Agreement for any amounts paid in settlement of any action
          or claim effected without its written consent. The Company shall be
          permitted to settle any action except that it shall not settle any
          action or claim in any manner which would impose any penalty or
          limitation on Indemnitee without Indemnitee's written consent. Neither
          the Company nor Indemnitee will unreasonably withhold its consent to
          any proposed settlement.

                  6. ADVANCEMENT AND REPAYMENT OF EXPENSES.

                    (a) In the event that Indemnitee employs his or her own
          counsel pursuant to Sections 5(b)(i) through (iii) above, the Company
          shall advance to Indemnitee, prior to any final disposition of any
          threatened or pending action, suit or proceeding, whether civil,
          criminal, administrative or investigative, any and all reasonable
          expenses (including legal fees and expenses) incurred in investigating
          or defending any such action, suit or proceeding within ten (10) days
          after receiving from Indemnitee copies of invoices presented to
          Indemnitee for such expenses.

                    (b) Indemnitee agrees that Indemnitee will reimburse the
          Company for all reasonable expenses paid by the Company in
          investigating or defending any civil or criminal action, suit or
          proceeding against Indemnitee in the event and only to the extent it
          shall be ultimately determined by a final judicial decision (from
          which there is no right of appeal) that Indemnitee is not entitled,
          under the provisions of the Code, the Bylaws, this Agreement or
          otherwise, to be indemnified by the Company for such expenses.

                                       4
<PAGE>

                    (c) Notwithstanding the foregoing, the Company shall not be
          required to advance such expenses to Indemnitee in respect of any
          action arising from or based upon any of the matters set forth in
          subsection (b) of Section 3 or if Indemnitee (i) commences any action,
          suit or proceeding as a plaintiff unless such advance is specifically
          approved by a majority of the Board of Directors or (ii) is a party to
          an action, suit or proceeding brought by the Company and approved by a
          majority of the Board which alleges willful misappropriation of
          corporate assets by Indemnitee, disclosure of confidential information
          in violation of Indemnitee's fiduciary or contractual obligations to
          the Company, or any other willful and deliberate breach in bad faith
          of Indemnitee's duty to the Company or its shareholders.

                  7.       ENFORCEMENT.

                    (a) The Company expressly confirms and agrees that it has
          entered into this Agreement and assumed the obligations imposed on the
          Company hereby in order to induce Indemnitee to continue as a
          director, officer, employee or other agent of the Company, and
          acknowledges that Indemnitee is relying upon this Agreement in
          continuing in such capacity.

                    (b) In the event Indemnitee is required to bring any action
          to enforce rights or to collect moneys due under this Agreement and is
          successful in such action, the Company shall reimburse Indemnitee for
          all Indemnitee's reasonable fees and expenses, including attorney's
          fees, in bringing and pursuing such action.

                  8. SUBROGATION. In the event of payment under this agreement,
the Company shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnitee, who shall execute all documents required and
shall do all acts that may be necessary to secure such rights and to enable the
Company effectively to bring suit to enforce such rights.

                  9. CONTINUATION OF OBLIGATIONS. All agreements and obligations
of the Company contained herein shall commence upon the date that Indemnitee
first became a member of the Board of Directors or an officer, employee or agent
of the Company, as the case may be, and shall continue during the period
Indemnitee is a director, officer, employee or agent of the Company (or is or
was serving at the request of the Company as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue thereafter so long as
Indemnitee shall be subject to any possible claim or threatened, pending or
completed action, suit or proceeding, whether civil, criminal or investigative,
by reason of the fact that Indemnitee was a director, officer, employee or agent
of the Company or serving in any other capacity referred to herein.

                  10. SURVIVAL OF RIGHTS. The rights conferred on Indemnitee by
this Agreement shall continue after Indemnitee has ceased to be a director,
officer, employee or other agent of the Company and shall inure to the benefit
of Indemnitee's heirs, executors and administrators.

                  11. NON-EXCLUSIVITY OF RIGHTS. The rights conferred on
Indemnitee by this Agreement shall not be exclusive of any other right which
Indemnitee may have or hereafter acquire under any statute, provision of the
Company's Certificate of Incorporation or Bylaws, agreement, vote of
stockholders or directors, or otherwise, both as to action in his official
capacity and as to action in another capacity while holding office; provided,
however, that this


                                       5
<PAGE>

Agreement shall supersede and replace any prior indemnification agreements
entered into by and between the Company and Indemnitee and that any such prior
indemnification agreement shall be terminated upon the execution of this
Agreement.

                  12. SEPARABILITY. Each of the provisions of this Agreement is
a separate and distinct agreement and independent of the others, so that if any
or all of the provisions hereof shall be held to be invalid or unenforceable for
any reason, such invalidity or unenforceability shall not affect the validity or
enforceability of the other provisions hereof or the obligation of the Company
to indemnify the Indemnitee to the full extent provided by the Bylaws or the
Code.

                  13. GOVERNING LAW. This Agreement shall be interpreted and
enforced in accordance with the laws of the State of Delaware.

                  14. BINDING EFFECT. This Agreement shall be binding upon
Indemnitee and upon the Company, its successors and assigns, and shall inure to
the benefit of Indemnitee, his or her heirs, personal representatives and
assigns and to the benefit of the Company, its successors and assigns.

termination or cancellation of this Agreement shall be effective unless it is in
writing and is signed by both parties hereto.

                  IN WITNESS WHEREOF, the parties hereto have executed this
Agreement on and as of the day and year first above written.

reasonable efforts to deliver possession of the Premises to Lessee by the
Commencement Date. If, despite said efforts. Lessor is unable to deliver
possession as agreed, Lessor shall not be subject to any liability therefor, nor

possession of the Premises. If possession is not delivered within sixty (60)
days after the Commencement Date, Lessee may, at its option, by notice in
writing within ten (10) days after the end of such sixty (60) day period, cancel
this Lease, in which event the Parties shall be discharged from all obligations
hereunder. If such written notice is not received by Lessor within said ten (10)
day period, Lessee's right to cancel shall terminate. Except as otherwise
provided, if possession is not tendered to Lessee by the Start Date and LessXX

evidence of insurance (Paragraph 8.5). Pending delivery of such evidence, Lessee
shall be required to perform all of the obligations under this Lease from and
after the Start Date, including the payment of Rent, notwithstanding Lessor's
election to withhold possession pending receipt of such evidence of insurance.
Further, if Lessee is required to perform any other conditions prior to or
concurrent with the Start Date, the Start Date shall occur but Lessor may elect
to withhold possession until such conditions are satisfied.

4. RENT.

     4.1. RENT DEFINED. All monetary obligations of Lessee to Lessor under the
terms of this Lease (except for the Security Deposit) are deemed to be rent
("Rent").

lawful money of the United States, without offset deduction (except as
specifically permitted in this Lease), on or before the day on which it is due.

calendar month shall be prorated based upon the actual number of days of said
month. Payment of Rent shall be made to Lessor at its address stated herein or
to such other persons or place as Lessor may from time to time designate in
writing. Acceptance of a payment which is less than the amount then due shall
not be a waiver of Lessor's rights to the balance of such Rent, regardless of
Lessor's endorsement of any check so stating.

Security Deposit as security for Lessee's faithful performance of its
obligations under this Lease. If Lessee fails to pay Rent, or otherwise Defaults

suffer or incur by reason thereof. If Lessor uses or applies all or any portion
of said Security Deposit, Lessee shall within ten (10) days after written
request therefor deposit monies with Lessor sufficient to restore said Security
Deposit to the XXX amount required by this Lease. If the Base Rent Increases
during the term of this Lease, Lessee shall, upon written request from Lessor,
deposit additional moneys with Lessor so that the total amount of the Security
Deposit shall at all times bear the same proportion to the increased Base Rent
as the initial Security Deposit bore to the initial Base Rent. Lessor shall not
be required to keep the Security Deposit separate form its general accounts.
Within fourteen (14) days after the expiration or termination of this Lease. If

6.   USE.

     6.1 USE. Lessee shall use and occupy the Premises only for the Agreed Use,
or any other legal use which is reasonably comparable thereto, and for no other
purpose. Lessee shall not use or permit the use of the Premises in a manner that
is unlawful, creates damage, waste or a nuisance, or that disturbs owners and/or
occupants of, or causes damage to neighboring properties. Lessor shall not
unreasonably withhold or delay its consent to any written request for a
modification of the Agreed Use, so long as the same will not impair the
structural integrity of the improvements on the Premises or the mechanical or
electrical systems therein, is not significantly more burdensome to the
Premises. If Lessor elects to withhold consent, Lessor shall within fifteen (15)
days after such request give written notification of same, which notice shall
include an explanation of Lessor's objections to the change in use.

     6.2 HAZARDOUS SUBSTANCES.

         a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS SUBSTANCE" as
used in this Lease shall mean any product, substance, or waste whose presence,
use, manufacture, disposal, transportation, or release, either by itself or in
combination with other materials expected to be on the Premises, is either: (i)
potentially injurious to the public health, safety or welfare, the environment
or the Premises, (ii) regulated or monitored by any governmental authority, or
(iii) a basis for potential liability of Lessor to any governmental agency or
third party under any applicable statute of law theory. Hazardous Substances
shall include, but not be limited to, hydrocarbons, petroleum, gasoline, and/or
crude oil or any products, by-products or fractions thereof. Lessee shall not
engage in any activity in or on the Premises which constitutes a Reportable Use
of Hazardous Substances without the express prior written consent of Lessor and
timely compliance (at Lessee's expense) with all Applicable Requirements.
"Reportable Use" shall mean (i) the installation or use of any above or below
ground storage tank, (ii) the generation, possession, storage, use,
transportation, or disposal of a Hazardous Substance that requires a permit
from, or with respect to which a report, notice, registration or business plan
is required to be filed with any governmental authority, and/or (iii) the
presence at the Premises of a Hazardous Substance with respect to which any
Applicable Requirements requires that a notice be given to persons entering or
occupying the Premises or neighboring properties. Notwithstanding the foregoing,
Lessee may use any ordinary and customary materials reasonably required to be
used in the normal course of the Agreed Use, so long as such use is in
compliance with all Applicable Requirements, is not a Reportable Use, and does
not expose the Premises or neighboring property to any meaningful risk of
contamination or damage or expose Lessor to any liability therefor. In addition,
Lessor may condition its consent to any Reportable Use upon receiving such
additional assurances as Lessor reasonably deems necessary to protect itself,
the public, the Premises and/or the environment against damage, contamination,
injury and/or liability, including, but not limited to, the installation (and
removal on or before Lease expiration or termination) of protective
modifications (such as concrete encasements) and/or increasing the Security
Deposit.

         (b) DUTY TO INFORM LESSOR. If Lessee knows, or has reasonable cause to
believe, that a Hazardous Substance has come to be located in, on, under or
about the Premises, other than as previously consented to by Lessor, Lessee
shall immediately give written notice of such fact to Lessor, and provide Lessor
with a copy of any report, notice, claim or other documentation which it has
concerning the presence of such Hazardous Substance.

         (c) LESSEE REMEDIATION. Lessee shall not cause or permit any Hazardous
Substance to be spilled or released in, on, under, or about the Premises
(including through the plumbing or sanitary sewer system) and shall promptly, at
Lessee's expense, take all investigatory and/or remedial action reasonably
recommended, whether or not formally ordered or required, for the cleanup of any
contamination of, and for the maintenance, security and/or monitoring of the
Premises or neighboring properties, that was caused or materially contributed to
by Lessee, or pertaining to or involving any Hazardous Substance brought onto
the Premises during the term of this Lease, by or for Lessee, or any related
third party.

         (d) LESSEE INDEMNIFICATION. Lessee shall indemnify, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, harmless from
and against any and all loss of rents and/or damages, liabilities, judgments,
claims, expenses, penalties, and attorneys' and consultants' fees arising out of
or involving any Hazardous Substance brought onto the Premises by or for Lessee,
or any related third party (provided, however, that Lessee shall have no
liability under this Lease with respect to underground migration of any
Hazardous Substance under the Premises from adjacent properties). Lessee's
obligations shall include, but not be limited to, the effects of any
contamination or injury to person, property or the environment created or
suffered by Lessee, and the cost of investigation, removal, remediation,
restoration and/or abatement, and shall survive the expiration or termination of
this Lease. NO TERMINATION, CANCELLATION OR RELEASE AGREEMENT ENTERED INTO BY
LESSOR AND LESSEE SHALL RELEASE LESSEE FROM ITS OBLIGATIONS UNDER THIS LEASE
WITH RESPECT TO HAZARDOUS SUBSTANCES, UNLESS SPECIFICALLY SO AGREED BY LESSOR IN
WRITING AT THE TIME OF SUCH AGREEMENT.

         (e) LESSOR INDEMNIFICATION. Lessor and its successors and assigns shall
indemnify, defend, reimburse and hold Lessee, its employees and lenders,
harmless from and against any and all environmental damages, including the cost
of remediation, which existed as a result of Hazardous Substances on the
Premises prior to the Start Date or which are caused by the gross negligence or
willful misconduct of Lessor, its agents or employees. Lessor's obligations, as
and when required by the Applicable Requirements, shall include, but not be
limited to, the cost of investigation, removal, remediation, restoration and/or
abatement, and shall survive the expiration or termination of this Lease.

         (f) INVESTIGATIONS AND REMEDIATIONS. Lessor shall retain the
responsibility and pay for any investigations or remediation measures required
by governmental entities having jurisdiction with respect to the existence of
Hazardous Substances on the Premises prior to the Start Date, unless such
remediation measure is required as a result of Lessee's use (including
"Alterations", as defined in paragraph 7.3(a) below) of the Premises, in which
event Lessee shall be responsible for such payment. Lessee shall cooperate fully
in any such activities at the request of Lessor, including allowing Lessor and
Lessor's agents to have reasonable access to the Premises at reasonable times in
order to carry out Lessor's investigative and remedial responsibilities.

         (g) LESSOR TERMINATION OPTION. If a Hazardous Substance Condition
occurs during the term of this Lease, unless Lessee is legally responsible
therefor (in which case Lessee shall make the investigation and remediation
thereof required by the Applicable Requirements and this Lease shall continue in
full force and effect, but subject to Lessor's rights under Paragraph 6.2(d) and
Paragraph 13), Lessor may, at Lessor's option, either (i) investigate and
remediate such Hazardous Substance Condition, if required, as soon as reasonably
possible at Lessor's expense, in which event this Lease shall continue in full
force and effect, or (ii) if the estimated cost to remediate such condition
exceeds twelve (12) times the then monthly Base Rent or $100,000, whichever is
greater, give written notice to Lessee, within thirty (30) days after receipt by
Lessor of knowledge of the occurrence of such Hazardous Substance Condition, of
Lessor's desire to terminate this Lease as of the date sixty (60) days following
the date of such notice. In the event Lessor elects to give a termination
notice, Lessee may, within ten (10) days thereafter, give written notice to
Lessor of Lessee's commitment to pay the amount by which the cost of the
remediation of such Hazardous Substance Condition exceeds an amount equal to
twelve (12) times the then monthly Base Rent or $100,000, whichever is greater,
Lessee shall provide Lessor with said funds or satisfactory assurance thereof
within thirty (30) days following such commitment. In such event, this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
remediation as soon as reasonably possible after the required funds are
available. If Lessee does not give such notice and provide the required funds or
assurance thereof within the time provided, this Lease shall terminate as of the
date specified in Lessor s notice of termination.

     6.3 LESSEE'S COMPLIANCE WITH APPLICABLE REQUIREMENTS. Except as otherwise
provided in this Lease, Lessee shall, at Lessee sole expense, fully, diligently
and in a timely manner, materially comply with all Applicable Requirements, the
requirements of any applicable fire insurance underwriter or rating bureau, and
the recommendations of Lessor's engineers and/or consultants which relate in any
manner to the Premises, without regard to whether said requirements are now in
effect or become effective after the Start Date. Lessee shall, within ten (10)
days after receipt of Lessor's written request, provide Lessor with copies of
all permits and other documents, and other information evidencing Lessee's
compliance with any Applicable Requirements specified by Lessor, and shall
immediately upon receipt, notify Lessor in writing (with copies of any documents
involved) of any threatened or actual claim, notice, citation, warning,
complaint or report pertaining to or involving the failure of Lessee or the
Premises to comply with any Applicable Requirements.

     6.4 INSPECTION; COMPLIANCE. Lessor and Lessor's "Lender" (as defined in
Paragraph 30 below) and consultants shall have the right to enter into Premises
at any time, in the case of an emergency, and otherwise at reasonable times, for
the purpose of inspecting the condition of the Premises and for verifying
compliance by Lessee with this Lease. The cost of any such inspections shall be
paid by Lessor, unless a violation of Applicable Requirements, or a
contamination is found to exist or be imminent, or the inspection is requested
or ordered by a governmental authority. In such case, Lessee shall upon request
reimburse Lessor for the cost of such inspections, so long as such inspection is
reasonably related to the violation or contamination (See Addendum Paragraph 53)

8.   INSURANCE: INDEMNITY.

     8.1 PAYMENT FOR INSURANCE. Lessee shall pay for all insurance required
under Paragraph 8 except to the extent of the cost attributable to liability
insurance carried by Lessor under Paragraph 8.2(b) in excess of $2,000,000 per
occurrence. Premiums for policy periods commencing prior to or extending beyond
the Lease term shall be prorated to correspond to the Lease term. Payment shall
be made by Lessee to Lessor within ten (10) days following receipt of an
invoice.

     8.2 LIABILITY INSURANCE.

        (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force a
Commercial General Liability Policy of Insurance protecting Lessee and Lessor
against claims for bodily injury, personal injury and property damage based upon
or arising out of the ownership, use, occupancy or maintenance of the Premises
and all areas appurtenant thereto. Such insurance shall be on an occurrence
basis providing single limit coverage in an amount not less than $2,000,000 per
occurrence with an "ADDITIONAL INSURED-MANAGERS OR LESSORS OF PREMISES
ENDORSEMENT" and contain the "AMENDMENT OF THE POLLUTION EXCLUSION ENDORSEMENT"
for damage caused by heat, smoke or fumes from a hostile fire. The Policy shall
not contain any intra-insured exclusions as between insured persons or
organizations, but shall include coverage for liability assumed under this Lease
as an "insured contract" for the performance of Lessee's indemnity obligations
under this Lease. The limits of such insurance shall not, however, limit the
liability of Lessee nor relieve Lessee of any obligation hereunder. All
insurance carried by Lessee shall be primary to and not contributory with any
similar insurance carried by Lessor, whose insurance shall be considered excess
insurance only.

         (b) CARRIED BY LESSOR. Lessor shall maintain liability insurance as
described in Paragraph 8.2(a), in addition to, and not lieu of, the insurance
required to be maintained by Lessee. Lessee shall not be named as an additional
insured therein.

     8.3 PROPERTY INSURANCE - BUILDING, IMPROVEMENTS AND RENTAL VALUE.

          (a) BUILDING AND IMPROVEMENTS. The Insuring Party shall obtain and
keep in force a policy or policies in the name of Lessor, with loss payable
to Lessor, any groundlessor, and to any Lender(s) insuring loss or damage
to the Premises. The amount of such insurance shall be equal to the full
replacement cost of the Premises, as the same shall exist from time to
time, or the amount required by any Lenders, but in no event more than the
commercially reasonable and available insurable value thereof. If Lessor is
the Insuring Party, however, Lessee Owned Alterations and Utility
Installations, Trade Fixtures, and Lessee's personal property shall be
insured by Lessee under Paragraph 8.4 rather than by Lessor. If the
coverage is available and commercially appropriate, such policy or policies
shall insure against all risks of direct physical loss or damage (except
the perils of flood and/or earthquake unless required by a Lender),
including coverage for debris removal and the enforcement of any Applicable
Requirements requiring the upgrading, demolition, reconstruction or
replacement of any portion of the Premises as the result of a covered loss.
Said policy or policies shall also contain an agreed valuation provision in
lieu of any coinsurance clause, waiver of subrogation, and inflation guard
protection causing an increase in the annual property insurance coverage
amount by a factor of not less than the adjusted U.S. Department of Labor
Consumer Price Index for All Urban Consumers for the city nearest to where
the Premises are located. If such insurance coverage has a deductible
clause, the deductible amount shall not exceed $1,000 per occurrence, and
Lessee shall be liable for such deductible amount in the event of an
Insured Loss.

          (b) RENTAL VALUE. The Insuring Party shall obtain and keep in force a
policy or policies in the name of Lessor with loss payable to Lessor and
any Lender, insuring the loss of the full Rent for one (1) year. Said
insurance shall provide that in the event the Lease is terminated by reason
of an insured loss, the period of indemnity for such coverage shall be
extended beyond the date of the completion of repairs or replacement of the
Premises, to provide for one full year's loss of Rent from the date of any
such loss. Said insurance shall contain an agreed valuation provision in
lieu of any coinsurance clause, and the amount of coverage shall be
adjusted annually to reflect the projected Rent otherwise payable by
Lessee, for the next twelve (12) month period. Lessee shall be liable for
any deductible amount in the event of such loss.

          (c) ADJACENT PREMISES. If the Premises are part of a larger building,
or of a group of buildings owned by Lessor which are adjacent to the
Premises, the Lessee shall pay for any increase in the premiums for the
property insurance of such building or buildings if said increase is caused
by Lessee's acts, omissions, use or occupancy of the Premises.

     8.4 LESSEE'S PROPERTY/BUSINESS INTERRUPTION INSURANCE.

         (a) PROPERTY DAMAGE. Lessee shall obtain and maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures, and Lessee Owned
Alterations and Utility Installations. Such insurance shall be full replacement
cost coverage with a deductible of not to exceed $1,000 per occurrence. The
proceeds from any such insurance shall be used by Lessee for the replacement of
personal property, Trade Fixtures and Lessee Owned Alterations and Utility
Installations. Lessee shall provide Lessor with written evidence that such
insurance is in force.

         (b) BUSINESS INTERRUPTION. Lessee shall obtain and maintain loss of
income and extra expense insurance in amounts as will reimburse Lessee for
direct or indirect loss of earnings attributable to all perils commonly insured
against by prudent lessees in the business of Lessee or attributable to
prevention of access to the Premises as a result of such perils.

         (c) NO REPRESENTATION OF ADEQUATE COVERAGE. Lessor makes no
representation that the limits or forms of coverage of insurance specified
herein are adequate to cover Lessee's property, business operations or
obligations under this Lease.

     8.5 INSURANCE POLICIES. Insurance required herein shall be by companies
duly licensed or admitted to transact business in the state where the Premises
are located, and maintaining during the policy term a "General Policyholders
Rating" of at least B+, V, as set forth in the most current issue of "Best's
Insurance Guide", or such other rating as may be required by a Lender. Lessee
shall not do or permit to be done anything which invalidates the required
insurance policies. Lessee shall, prior to the Start Date, deliver to Lessor
certified copies of policies of such insurance or certificates evidencing the
existence and amounts of the required insurance. No such policy shall be
cancelable or subject to modification except after thirty (30) days prior
written notice to Lessor. Lessee shall, at least thirty (30) days prior to the
expiration of such policies, furnish Lessor with evidence of renewals or
"insurance binders" evidencing renewal thereof, or Lessor may order such
insurance and charge the cost thereof to Lessee, which amount shall be payable
by Lessee to Lessor upon demand. Such policies shall be for a term of at least
one year, or the length of the remaining term of this Lease, whichever is less.
If either Party shall fail to procure and maintain the insurance required to be
carried by it, the other Party may, but shall not be required to, procure and
maintain the same.

     8.6 WAIVER OF SUBROGATION. Without affecting any other rights or remedies,
Lessee and Lessor each hereby release and relieve the other, and waive their
entire right to recover damages against the other, for loss of or damage to its
property arising out of or incident to the perils required to be insured against
herein. The effect of such releases and waivers is not limited by the amount of
insurance carried or required, or by any deductibles applicable hereto. The
Parties agree to have their respective property damage insurance carriers waive
any right to subrogation that such companies may have against Lessor or Lessee,
as the case may be, so long as the insurance is not invalidated thereby.

     8.7 INDEMNITY. Except for Lessor's gross negligence or willful misconduct,
Lessee shall indemnify, protect, defend and hold harmless the Premises, Lessor
and its agents, Lessor's master or ground lessor, partners and Lenders, from and
against any and all claims, loss of rents and/or damages, liens, judgments,
penalties, attorneys' and consultants' fees, expenses and/or liabilities arising
out of, involving, or in connection with, the use and/or occupancy of the
Premises by Lessee. If any action or proceeding is brought against Lessor by
reason of any of the foregoing matters, Lessee shall upon notice defend the same
at Lessee's expense by counsel reasonably satisfactory to Lessor and Lessor
shall cooperate with Lessee in such defense. Lessor need not have first paid any
such claim in order to be defended or indemnified.

     8.8 EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be liable for
injury or damage to the person or goods, wares, merchandise or other property of
Lessee. Lessee's employees, contractors, invitees, customers, or any other
person in or about the Premises, whether such damage or injury is caused by or
results from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects or pipes, fire sprinklers, wires,
appliances, plumbing, HVAC or lighting fixtures, or from any other cause,
whether the said injury or damage results from conditions arising upon the
Premises or upon other portions of the Building of which the Premises are a
part, or from other sources or places. Lessor shall not be liable for any damage
arising from any act or neglect of any other tenant of Lessor. Notwithstanding
Lessor's negligence or breach of this Lease, Lessor shall under no circumstances
be liable for injury to Lessee's business or for any loss of income or profit
therefrom.

insurance described in Paragraph 8.3(a) irrespective of any deductible amounts
or coverage limits involved.

         (d) "REPLACEMENT COST" shall mean the cost to repair or rebuild the
improvements owned of Lessor at the time of the occurrence to their condition
existing immediately prior thereto, including demolition, debris removal and
upgrading required by the operation of Applicable Requirements, and without
deduction for depreciation.

         (e) "HAZARDOUS SUBSTANCE CONDITION" shall mean the occurrence or
discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in Paragraph 6.2(a), in, on, or under the
Premises.

     9.2 PARTIAL DAMAGE - INSURED LOSS. If a Premises Partial Damage that is an
Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such damage
(but not Lessee's Trade Fixtures or Lessee Owned Alterations and Utility
Installations) as soon as reasonably possible and this Lease shall continue in
full force and effect: provided, however, that Lessee shall, at Lessor's
election, make the repair of any damage or destruction the total cost to repair
of which is $10,000 or less, and, in such event, Lessor shall make any
applicable insurance proceeds available to Lessee on a reasonable basis for that
purpose. Notwithstanding the foregoing, if the required insurance was not in
force or the insurance proceeds are not sufficient to effect such repair, the
Insuring Party shall promptly contribute the shortage in proceeds (except as to
the deductible which is Lessee's responsibility) as and when required to
complete said repairs. In the event, however, such shortage was due to the fact
that, by reason of the unique nature of the improvements, full replacement cost
insurance coverage was not commercially reasonable and available, Lessor shall
have no obligation to pay for the shortage in insurance proceeds or to fully
restore the unique aspects of the Premises unless Lessee provides Lessor with
the funds to cover same, or adequate assurance thereof, within ten (10) days
following receipt of written notice of such shortage and request therefor. If
Lessor receives said funds or adequate assurance thereof within said ten (10)
day period, the party responsible for making the repairs shall complete them as
soon as reasonably possible and this Lease shall remain in full force and
effect. If such funds or assurance are not received, Lessor may nevertheless
elect by written notice to Lessee within ten (10) days thereafter to: (i) make
such restoration and repair as is commercially reasonable with Lessor paying any
shortage in proceeds, in which case this Lease shall remain in full force and
effect; or (ii) have this Lease terminate thirty (30) days thereafter. Lessee
shall not be entitled to reimbursement of any funds contributed by Lessee to
repair any such damage or destruction. Premises Partial Damage due to flood or
earthquake shall be subject to Paragraph 9.3, notwithstanding that there may be
some insurance coverage, but the net proceeds of any such insurance shall be
made available for the repairs if made by either Party

     9.3 PARTIAL DAMAGE - UNINSURED LOSS. If a Premises Partial Damage that is
not an Insured Loss occurs, unless caused by a negligence or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense),
Lessor may either: (i) repair such damage as soon as reasonably possible at
Lessor's expense, in which event this Lease shall continue in full force and
effect, or (ii) terminate this Lease by giving written notice to Lessee within
thirty (30) days after receipt by Lessor of knowledge of the occurrence of such
damage. Such termination shall be effective sixty (60) days following the date
of such notice. In the event Lessor elects to terminate this Lease, Lessee shall
have the right within ten (10) days after receipt of the termination notice to
give written notice to Lessor of Lessee's commitment to pay for the repair of
such damage without reimbursement from Lessor. Lessee shall provide Lessor with
said funds or satisfactory assurance thereof within thirty (30) days after
making such commitment. In such event this Lease shall continue in full force
and effect, and Lessor shall proceed to make such repairs a soon as reasonably
possible after the required funds are available. If Lessee does not make the
required commitment, this Lease shall terminate as of the date specified in the
termination notice.

     9.4 TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if a
Premises Total Destruction occurs, this Lease shall terminate sixty (60) days
following such Destruction. If the damage or destruction was caused by the gross
negligence or willful misconduct of Lessee, Lessor shall have the right to
recover Lessor's damages from Lessee, except as provided in Paragraph 8.6.

     9.5 DAMAGE NEAR END OF TERM. If at any time during the last six (6) months
of this Lease there is damage for which the cost to repair exceeds one (1)
month's Base Rent, whether or not an Insured Loss, Lessor may terminate this
Lease effective sixty (60) days following the date of occurrence of such damage
by giving a written termination notice to Lessee within thirty (30) days after
the date of occurrence of such damage.

     9.6 ABATEMENT OF RENT; LESSEE'S REMEDIES.

         (a) ABATEMENT. In the event of Premises Partial Damage or Premises
Total Destruction or a Hazardous Substance Condition for which Lessee is not
responsible under this Lease, the Rent payable by Lessee for the period required
for the repair, remediation or restoration of such damage shall be abated in
proportion to the degree to which Lessee's use of the Premises is impaired. All
other obligations of Lessee hereunder shall be performed by Lessee, and Lessor
shall have no liability for any such damage, destruction, remediation, repair or
restoration except as provided herein.

     (b) REMEDIES. If Lessor shall be obligated to repair or restore the
Premises and does not commence, in a substantial and meaningful way, such repair
or restoration within ninety (90) days after such obligation shall accrue,
Lessee may, at any time prior to the commencement of such repair or restoration,
give written notice to Lessor and to any Lenders of which Lessee has actual
notice, of Lessee's election to terminate this Lease on a date not less than
sixty (60) days following the giving of such notice, if Lessee gives such notice
and such repair or restoration is not commenced within thirty (30) days
thereafter, this Lease shall terminate as of the date specified in said notice.
If the repair or restoration is commenced within said thirty (30) days, this
Lease shall continue in full force and effect. "COMMENCE" shall mean either the
unconditional authorization of the preparation of the required plans, or the
beginning of the actual work on the Premises, whichever first occurs.

     9.7 TERMINATION-ADVANCE PAYMENTS. Upon termination of this Lease pursuant
to Paragraph 6.2(g) or Paragraph 9, an equitable adjustment shall be made
concerning advance Base Rent and any other advance payments made by Lessee to
Lessor. Lessor shall, in addition, return to Lessee so much of Lessee's Security
Deposit as has not been, or is not then required to be, used by Lessor.

     9.8 WAIVE STATUTES. Lessor and Lessee agree that the terms of this Lease
shall govern the effect of any damage to or destruction the Premises with
respect to the termination of this Lease and hereby waive the provisions of any
present or future statute to the extent inconsistent herewith.

10.  REAL PROPERTY TAXES.

     10.1  DEFINITION OF "REAL PROPERTY TAXES. As used herein, the term "Real
Property Taxes" shall include any form of assessment real estate, general,
special, ordinary or extraordinary, or rental levy or tax other than
inheritance, personal income or estate taxes); improvement bond; and/or license
fee imposed upon or levied against any legal or equitable interest of Lessor in
the Premises. Lessor's right to other income therefrom, and/or Lessor's business
of leasing, by any authority having the direct or indirect power to tax and
where the funds are generated

                                     PAGE 6


<PAGE>

with reference to the Building address and where the proceeds so generated
are to be applied by the city, county or other local taxing authority of a
jurisdiction within which the Premises are located. The term "Real Property
Taxes" shall also include any tax, fee, levy, assessment or charge, or any
increase therein, imposed by reason of events occurring during the term of this
Lease, including but not limited to, a change in the ownership of the Premises.

     10.2

         (a) PAYMENT OF TAXES. Lessee shall pay the Real Property Taxes
applicable to the Premises during the term of this Lease. Subject to Paragraph
10.2(b), all such payments shall be made at least ten (10) days prior to any
delinquency date. Lessee shall promptly furnish Lessor with satisfactory
evidence that such taxes have been paid. If any such taxes shall cover any
period of time prior to or after the expiration or termination of this Lease,
Lessee's share of such taxes shall be prorated to cover only that portion of the
tax bill applicable to the period that this Lease is in effect, and Lessor shall
reimburse Lessee for any overpayment. If Lessee shall fail to pay any required
Real Property Taxes, Lessor shall have the right to pay the same, and Lessee
shall reimburse Lessor therefor upon demand.

         (b) ADVANCE PAYMENT. In the event Lessee incurs a late charge on any
Rent payment, Lessor may, at Lessor's option, estimate the current Real Property
Taxes, and require that such taxes be paid in advance to Lessor by Lessee,
either: (i) in a lump sum amount equal to the installment due, at least twenty
(20) days prior to the applicable delinquency date, or (ii) monthly in advance
with the payment of the Base Rent. If Lessor elects to require payment monthly
in advance, the monthly payment shall be an amount equal to the amount of the
estimated installment of taxes divided by the number of months remaining before
the month in which said installment becomes delinquent. When the actual amount
of the applicable tax bill is known, the amount of such equal monthly advance
payments shall be adjusted as required to provide the funds needed to pay the
applicable taxes. If the amount collected by Lessor is insufficient to pay such
Real Property Taxes when due, Lessee shall pay Lessor, upon demand, such
additional sums as are necessary to pay such obligations. All moneys paid to
Lessor under this Paragraph may be intermingled with other moneys of Lessor and
shall not bear interest. In the event of a Breach by Lessee in the performance
of its obligations under this Lease, then any balance of funds paid to Lessor
under the provisions of this Paragraph may at the option of Lessor, be treated
as an additional Security Deposit.

     10.3 JOINT ASSESSMENT. If the Premises are not separately assessed,
Lessee's liability shall be an equitable proportion of the Real Property Taxes
for all of the land and improvements included within the tax parcel assessed,
such proportion to be conclusively determined by Lessor from the respective
valuations assigned in the assessor's work sheets or such other information as
may be reasonably available.

     10.4  PERSONAL PROPERTY TAXES. Lessee shall pay, prior to delinquency, all
taxes assessed against and levied upon Lessee Owned Alterations, Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee. When possible, Lessee shall cause such property to be assessed and
billed separately from the real property of Lessor. If any of Lessee's said
personal property shall be assessed with Lessor's real property, Lessee shall
pay Lessor the taxes attributable to Lessee's property within ten (10) days
after receipt of a written statement.

11. UTILITIES. Lessee shall pay for all water, gas, heat, light, power,
telephone, trash disposal and other utilities and services supplied to the
Premises, together with any taxes thereon. If any such services are not
separately metered to Lessee, Lessee shall pay a reasonable proportion, to be
determined by Lessor, of all charges jointly metered.

12. ASSIGNMENT AND SUBLETTING. (See Addendum Paragraph 55)

     12.1 LESSOR'S CONSENT REQUIRED.

         (a) Lessee shall not voluntarily or by operation of law assign,
transfer, mortgage or encumber (collectively, "ASSIGN OR ASSIGNMENT") or sublet
all or any part of Lessee's interest in this Lease or in the Premises without
Lessor's prior written consent.

         (b) A change in the control of Lessee shall constitute an assignment
requiring consent. The transfer, on a cumulative basis, of fifty percent (50%)
or more of the voting control of Lessee shall constitute a change in control for
this purpose.

         (d) An assignment or subletting without consent shall, at Lessor's
option, be a Default curable after notice per Paragraph 13.1(c), or a noncurable
Breach without the necessity of any notice and grace period. If Lessor elects to
treat such unapproved assignment or subletting as a noncurable Breach, Lessor
may either: (i) terminate this Lease, or (ii) upon thirty (30) days written
notice, increase the monthly Base Rent to one hundred ten percent (110%) of the
Base Rent then in effect. Further, in the event of such Breach and rental
adjustment, (i) the purchase price of any option to purchase the Premises held
by Lessee shall be subject to similar adjustment to one hundred ten percent
(110%) of the price previously in effect, and (ii) all fixed and non-fixed
rental adjustments scheduled during the remainder of the Lease term shall be
increased to One Hundred Ten Percent (110%) of the scheduled adjusted rent.

         (e) Lessee's remedy for any breach of Paragraph 12.1 by Lessor shall be
limited to compensatory damages and/or injunctive relief.

     12.2  TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING,

         (a) Regardless of Lessor's consent, any assignment or subletting shall
not: (i) be effective without the express written assumption by such assignee or
sublessee of the obligations of Lessee under this Lease, (ii) release Lessee of
any obligations hereunder, or (iii) alter the primary liability of Lessee for
the payment of Rent or for the performance of any other obligations to be
performed by Lessee.

         (b) Lessor may accept Rent or performance of Lessee's obligations from
any person other than Lessee pending approval or disapproval of an assignment.
Neither a delay in the approval or disapproval of such assignment nor the
acceptance of Rent or performance shall constitute a waiver or estoppel of
Lessor's right to exercise its remedies for Lessee's Default or Breach.

         (c) Lessor's consent to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting.

         (d) In the event of any Default or Breach by Lessee, Lessor may proceed
directly against Lessee, any Guarantors or anyone else responsible for the
performance of Lessee's obligations under this Lease, including any assignee or
sublessee, without first exhausting Lessor's remedies against any other person
or entity, responsible therefore to Lessor, or any security held by Lessor.

         (e) Each request for consent to an assignment or subletting shall be in
writing, accompanied by information relevant to Lessor's determination as to the
financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
required modification of the Premises, if any (See Addendum Paragraph 55 (d))

         (f) Any assignee of, or sublessee under, this Lease shall, by reason of
accepting such assignment or entering into such sublease, be deemed to have
assumed and agreed to conform and comply with each and every term, covenant,
condition and obligation herein to be observed or performed by Lessee during the
term of said assignment or sublease, other than such obligations as are contrary
to or inconsistent with provisions or an assignment or sublease to which Lessor
has specifically consented to in writing.

     12.3 ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

         (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all Rent payable on any sublease, and Lessor may collect such Rent
and apply same toward Lessee's obligations under this Lease; provided, however,
that until a Breach shall occur in the performance of Lessee's obligations,
Lessee may collect said Rent. Lessor shall not, by reason of the foregoing or
any assignment of such sublease, nor by reason of the collection of Rent, be
deemed liable to the sublessee for any failure of Lessee to perform and comply
with any of Lessee's obligations to such sublessee. Lessee hereby irrevocably
authorizes and directs any such sublease, upon receipt of a written notice

                                     PAGE 7


<PAGE>

from Lessor stating that a Breach exists in the performance of Lessee's
obligations under this Lease, to pay to Lessor all Rent due and to become due
under the sublease. Sublessee shall rely upon any such notice from Lessor and
shall pay all Rents to Lessor without any obligation or right to inquire as to
whether such Breach exists, notwithstanding any claim from Lessee to the
contrary.

         (b) In the event of a Breach by Lessee, Lessor may, at its option,
require sublessee to attorn to Lessor, in which event Lessor shall undertake the
obligations of the sublessor under such sublease from the time of the exercise
of said option to the expiration of such sublease; provided, however, Lessor
shall not be liable for any prepaid rents or security deposit paid by such
sublessee to such sublessor or for any prior Defaults or Breaches of such
sublessor.

          (c) Any matter requiring the consent of the sublessor under a sublease
shall also require the consent of Lessor.

          (d) No sublessee shall further assign or sublet all or any part of the
Premises without Lessor's prior written consent.

          (e) Lessor shall deliver a copy of any notice of Default or Breach by
Lessee to the sublessee, who shall have the right to cure the Default of
Lessee within the grace period, if any, specified in such notice. The
sublessee shall have a right of reimbursement and offset from and against
Lessee for any such Defaults cured by the sublessee.

13. DEFAULT; BREACH; REMEDIES.

     13.1 DEFAULT; BREACH. A "Default" is defined as a failure by the Lessee to
comply with or perform any of the terms, covenants, conditions or rules under
this Lease. A "Breach" is defined as the occurrence of one or more of the
following Defaults, and the failure of Lessee to cure such Default within any
applicable grace period:

          (a) The abandonment of the Premises; or the vacating of the Premises
without providing a commercially reasonable level of security or where the
coverage of the property insurance described in Paragraph 8.3 is jeopardized as
a result thereof, or without providing reasonable assurances to minimize
potential vandalism.

          (b) The failure of Lessee to make any payment of Rent or any Security
Deposit required to be made by Lessee hereunder, whether to Lessor or to a third
party, when due, to provide reasonable evidence of insurance or surety bond, or
to fulfill any obligation under this Lease which endangers or threatens life or
property, where such failure continues for a period of three (3) business days
following written notice to Lessee.

          (c) The failure by Lessee to provide (i) reasonable written evidence
of compliance with Applicable Requirements, (ii) the service contracts, (iii)
the rescission of an unauthorized assignment or subletting, (iv) a Estoppel
Certificate, (v) a requested subordination, (vi) evidence concerning any
guaranty and/or Guarantor, (vii) any document requested under Paragraph 42
(easements), or (viii) any other documentation or information which Lessor may
reasonably require of Lessee under the terms of this Lease, where any such
failure continues for a period of ten (10) days following written notice to
Lessee.

          (d) A Default by Lessee as to the terms, covenants, conditions or
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof,
other than those described in subparagraphs 13.1(a), (b) or (c), above, where
such Default continues for a period of thirty (30) days after written notice;
provided, however, that if the nature of Lessee's Default is such that more than
thirty (30) days are reasonably required for its cure, then it shall not be
deemed to be a Breach if Lessee commences such cure within said thirty (30) day
period and thereafter diligently prosecutes such cure to completion.

          (e) The occurrence of any of the following events: (i) the making of
any general arrangement or assignment for the benefit of creditors; (ii)
becoming a "debtor" as defined in 11 U.S.C. Section 101 or any successor statute
thereto (unless, in the case of a petition filed against Lessee, the same is
dismissed within sixty (60) days); (iii) the appointment of a trustee or
receiver to take possession of substantially all of Lessee's assets located at
the Premises or of Lessee's interest in this Lease, where possession is not
restored to Lessee within thirty (30) days; or (iv) the attachment, execution or
other judicial seizure of substantially all of Lessee's assets located at the
Premises or of Lessee's interest in this Lease, where such seizure is not
discharged within thirty (30) days; provided, however, in the event that any
provision of this subparagraph (e) is contrary to any applicable law, such
provision shall be of no force or effect, and not affect the validity of the
remaining provisions.

          (f) The discovery that any financial statement of Lessee or of any
Guarantor given to Lessor was materially false.

          (g) If the performance of Lessee's obligations under this Lease is
guaranteed: (i) the death of a Guarantor, (ii) the termination of Guarantor's
liability with respect to this Lease other than in accordance with the terms of
such guaranty, (iii) a Guarantor's becoming insolvent or the subject of a
bankruptcy filing, (iv) a Guarantor's refusal to honor the guaranty, or (v) a
Guarantor's breach of its guaranty obligation on an anticipatory basis, and
Lessee's failure, within sixty (60) days following written notice of any such
event, to provide written alternative assurance or security, which, when coupled
with the then existing resources of Lessee, equals or exceeds the combined
financial resources of Lessee and the Guarantors that existed at the time of
execution of this Lease.

     13.2 REMEDIES. If Lessee fails to perform any of its affirmative duties or
obligations, within ten (10) days after written notice (or in case of an
emergency, without notice), Lessor may, at its option, perform such duty or
obligation on Lessee's behalf, including but not limited to the obtaining of
reasonably required bonds, insurance policies, or governmental licenses, permits
or approvals. The costs and expenses of any such performance by Lessor shall be
due and payable by Lessee upon receipt of invoice therefor. If any check given
to Lessor by Lessee shall not be honored by the bank upon which it is drawn,
Lessor, at its option, may require all future payments to be made by Lessee to
be by cashier's check. In the event of a Breach, Lessor may, with or without
further notice or demand, and without limiting Lessor in the exercise of any
right or remedy which Lessor may have by reason of such Breach:

          (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease shall terminate and Lessee shall
immediately surrender possession to Lessor. In such event Lessor shall be
entitled to recover from Lessee: (i) the unpaid Rent which had been earned at
the time of termination; (ii) the worth at the time of award of the amount by
which the unpaid rent which would have been earned after termination until the
time of award exceeds the amount of such rental loss that the Lessee proves
could have been reasonably avoided; (iii) the worth at the time of award of the
amount by which the unpaid rent for the balance of the term after the time of
award exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided: and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of any leasing commission paid by Lessor in connection with this Lease
applicable to the unexpired term of this Lease. The worth at the time of award
of the amount referred to in provision (iii) of the immediately preceding
sentence shall be computed by discounting such amount at the discount rate of
the Federal Reserve Bank of the District within which the Premises are located
at the time of award plus one percent (1%). Efforts by Lessor to mitigate
damages caused by Lessee's Breach of this Lease shall not waive Lessor's right
to recover damages under Paragraph 12. If termination of this Lease obtained
through the provisional remedy of unlawful detainer, Lessor shall have the right
to recover in such proceeding any unpaid Rent and damages as are recoverable
therein, or Lessor may reserve the right to recover all or any part thereof in a
separate suit. If a notice and grace period required under Paragraph 13.1 was
not previously given, a notice to pay rent or quit, or to perform or quit given
to Lessee under the unlawful detainer statute shall also constitute the notice
required by Paragraph 13.1. In such case, the applicable grace period required
by Paragraph 13.1 and the unlawful detainer statute shall run concurrently, and
the failure of Lessee to cure the Default within the greater of the two such
grace periods shall constitute both an unlawful detainer and a Breach of this
Lease entitling Lessor to the remedies provided for in this Lease and/or by said
statute.

         (b) Continue the Lease and Lessee's right to possession and recover the
Rent as it becomes due, in which event Lessee may sublet or assign, subject only
to reasonable limitations. Acts of maintenance, efforts to relet, and/or the
appointment of a receiver to protect the Lessor's interests, shall not
constitute a termination of the Lessee's right to possession.

         (c) Pursue any other remedy now or hereafter available under the laws
or judicial decisions of the state wherein the Premises are located. The
expiration or termination of this Lease and/or the termination of Lessee's right
to possession shall not relieve Lessee from liability

                                     PAGE 8


<PAGE>

under any indemnity provisions of this Lease as to matters occurring or
accruing during the term hereof or by reason of Lessee's occupancy of the
Premises.

     13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee
of Rent will cause Lessor to incur costs not contemplated by this Lease, the
exact amount of which will be extremely difficult to ascertain. Such costs
include, but are not limited to, processing and accounting charges, and late
charges which may be imposed upon Lessor by any Lender. Accordingly, if any Rent
shall not be received by Lessor within five (5) days after such amount shall be
due, then, without any requirement for notice to Lessee, Lessee shall pay to
Lessor a one-time late charge equal to six percent (6%) of each such overdue
amount. The parties hereby agree that such late charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of such late
payment. Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent the exercise of any of the other rights and remedies granted hereunder.
In the event that a late charge is payable hereunder, whether or not collected,
for three (3) consecutive installments of Base Rent, then notwithstanding any
provision of this Lease to the contrary, Base Rent shall, at Lessor's option,
become due and payable quarterly in advance.

     13.5  INTEREST. Any monetary payment due Lessor hereunder, other than late
charges, not received by Lessor, when due as to scheduled payments (such as Base
Rent) or within thirty (30) days following the date on which it was due for
non-scheduled payment, shall bear interest from the date when due, as to
scheduled payments, or the thirty-first (31st) day after it was due as to
non-scheduled payments. The interest ("Interest") charged shall be equal to the
prime rate reported in the Wall Street Journal as published closest prior to the
date when due plus two percent (2%) but shall not exceed the maximum rate
allowed by law. Interest is payable in addition to the potential late charge
provided for in Paragraph 13.4.

     13.6  BREACH BY LESSOR.

         (a) NOTICE OF BREACH. Lessor shall not be deemed in breach of this
Lease unless Lessor fails within a reasonable time to perform an obligation
required to be performed by Lessor. For purposes of this Paragraph, a reasonable
time shall in no event be less than thirty (30) days after receipt by Lessor,
and any Lender whose name and address shall have been furnished Lessee in
writing for such purpose, of written notice specifying wherein such obligation
of Lessor has not been performed; provided, however, that if the nature of
Lessor's obligation is such that more than thirty (30) days are reasonably
required for its performance, then Lessor shall not be in breach if performance
is commenced within such thirty (30) day period and thereafter diligently
pursued to completion.

14. CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(collectively "Condemnation"), this Lease shall terminate as to the part taken
as of the date the condemning authority takes title or possession, whichever
first occurs. If more than ten percent (10%) of any building portion of the
premises, or more than twenty-five percent (25%) of the land area portion of the
premises not occupied by any building, is taken by Condemnation, Lessee may, at
Lessee's option, to be exercised in writing within ten (10) days after Lessor
shall have given Lessee written notice of such taking (or in the absence of such
notice, within ten (10) days after the condemning authority shall have taken
possession) terminate this Lease as of the date the condemning authority takes
such possession. If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Base Rent shall be reduced in proportion
to the reduction in utility of the Premises caused by such Condemnation.
Condemnation awards and/or payments shall be the property of Lessor, whether
such award shall be made as compensation for diminution in value of the
leasehold, the value of the part taken, or for severance damages; provided,
however, that Lessee shall be entitled to any compensation for Lessee's
relocation expenses, loss of business goodwill and/or Trade Fixtures, without
regard to whether or not this Lease is terminated pursuant to the provisions of
this Paragraph. All Alterations and Utility Installations made to the Premises
by Lessee, for purposes of Condemnation only, shall be considered the property

transfer or assignment and delivery of the Security Deposit, as aforesaid, the
prior Lessor shall be relieved of all liability with respect to the obligations
and/or covenants under this Lease thereafter to be performed by the Lessor.
Subject to the foregoing, the obligations and/or covenants in this Lease to be
performed by the Lessor shall be binding only upon the Lessor as hereinabove
defined. Notwithstanding the above, and subject to the provisions of Paragraph
20 below, the original Lessor under this Lease, and all subsequent holders of
the Lessor's interest in this Lease shall remain liable and responsible with
regard to the potential duties and liabilities of Lessor pertaining to Hazardous
Substances as outlined in Paragraph 6 above.

18. SEVERABILITY. The invalidity of any provision of this Lease, as
determined by a court of competent jurisdiction, shall in no way affect the
validity of any other provision hereof.

19. DAYS. Unless otherwise specifically indicated to the contrary, the word
"days" as used in this Lease shall mean and refer to calendar days.

20. LIMITATION ON LIABILITY. Subject to the provisions of Paragraph 17
above, the obligations of Lessor under this Lease shall not constitute personal
obligations of Lessor, the individual partners of Lessor or its or their
individual partners, directors, officers or shareholders, and Lessee shall look
to the Premises, and to no other assets of Lessor, for the satisfaction of any
liability of Lessor with respect to this Lease. and shall not seek recourse
against the individual partners of Lessor, or its or their individual partners,
directors, officers or shareholders, or any of the personal assets for such
satisfaction.

21. TIME OF ESSENCE. Time is of the essence with respect to the performance
of all obligations to be performed or observed by the Parties under this Lease.

22. NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER. This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement or understanding shall be effective.

23. NOTICES.

     23.1  NOTICE REQUIREMENTS. All notices required or permitted by this Lease
shall be in writing and may be delivered in person (by hand or by courier) or
may be sent by regular, certified or registered mail or U.S. Postal Service
Express Mail, with postage prepaid, or by facsimile transmission, and shall be
deemed sufficiently given if served in a manner specified in this Paragraph 23.
The addresses noted adjacent to a Party's signature on this Lease shall be
that Party's address for delivery or mailing of notices. Either Party may by
written notice to the other specify a different address for notice, except that
upon Lessee's taking possession of the Premises, the Premises shall constitute
Lessee's address for notice. A copy of all notices to Lessor shall be
concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate in writing.

     23.2 DATE OF NOTICE. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon, if sent
by regular mail the notice shall be deemed given forty-eight (48) hours after
the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United State Express Mail or overnight courier that
guarantee next day delivery shall be deemed given twenty-four (24) hours after
delivery of the same to the Postal Service or courier. Notices transmitted by
facsimile transmission or similar means shall be deemed delivered upon telephone
confirmation of receipt, provided a copy is also delivered via delivery or mail.
If notice is received on a Saturday, Sunday or legal holiday, it shall be deemed
received on the next business day.

24. WAIVERS. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or of any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to or approval of, any subsequent or similar act
by Lessee, or be construed as the basis of an estoppel to enforce the provision
or provisions of this Lease requiring such consent. The acceptance of Rent by
Lessor shall not be a waiver of any Default or Breach by Lessee. Any payment by
Lessee may be accepted by Lessor on account of moneys or damages due Lessor,
notwithstanding any qualifying statements or condition made by Lessee in
connection therewith, which such statements and/or conditions shall be of no
force or effect whatsoever unless specifically agreed to in writing by Lessor at
or before the time of deposit of such payment.

26. NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or termination of this Lease.
In the event that Lessee holds over, then the Base Rent shall be increased to
one hundred fifty percent (150%) of the Base Rent applicable during the month
immediately preceding the expiration or termination. Nothing contained herein
shall be construed as consent to Lessor to any holding over by Lessee.

27.CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with any other remedies
at law or in equity.

28. COVENANTS AND CONDITIONS; CONSTRUCTION OF AGREEMENT. All provisions
of this Lease to be observed or performed by Lessee are both covenants and
conditions. In construing this Lease, all headings and titles are for the
convenience of the parties only and shall not be considered a part of this
Lease. Whenever required by the context, the singular shall include the plural
and vice versa. This Lease shall not be construed as if prepared by one of the
parties, but rather according to its fair meaning as a whole, as if both parties
had prepared it.

29. BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the
parties, their personal representatives, successors and assigns and be governed
by the laws of the State in which the Premises are located. Any litigation
between the Parties hereto concerning this Lease shall be initiated in the
county in which the Premises are located.

30. SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

     30.1 SUBORDINATION. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed upon the Premises, to any and all advances made on the security
thereof, and to all renewals, modifications, and extensions thereof. Lessee
agrees that the holders of any such Security Devices (in this Lease together
referred to as "Lender") shall have no liability or obligations to perform any
of the obligations of Lessor under this Lease. Any Lender may elect to have this
Lease and/or any Option granted hereby superior to the lien of its Security
Device by giving written notice thereof to Lessee, whereupon this Lease and such
Options shall be deemed prior to such Security Device, notwithstanding the
relative dates of the documentation or recordation thereof.

     30.2  ATTORNMENT. Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender of any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new

                                     PAGE 10


<PAGE>

owner shall not: (i) be liable for any act or omission of any prior lessor
or with respect to events occurring prior to acquisition of ownership; (ii) be
subject to any offsets or defenses which Lessee might have against any prior
lessor, or (iii) be bound by prepayment of more than one (1) month's rent.

    30.3  NON-DISTURBANCE. With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving a commercially reasonable non-disturbance
agreement (a "NON-DISTURBANCE AGREEMENT") from the Lender which Non-Disturbance
Agreement provides that Lessee's possession of the Premises, and this Lease,
including any options to extend the term hereof, will not be disturbed so long
as Lessee is not in Breach hereof and attorns to the record owner of the
Premises. Further, within sixty (60) days after the execution of this Lease,
Lessor shall use its commercially reasonable efforts to obtain a Non-Disturbance
Agreement from the holder of any pre-existing Security Device which is secured
by the Premises. In the event that Lessor is unable to provide the
Non-Disturbance Agreement within sixty (60) days, then Lessee may, at Lessees
option, directly contact Lessor's lender and attempt to negotiate for the
execution and delivery of a Non-Disturbance Agreement.

     30.4 SELF-EXECUTING. The agreements contained in this Paragraph 30 shall be
effective without the execution of any further documents; provided, however,
that, upon written request from Lessor or a Lender in connection with a sale,
financing or refinancing of the Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required to separately document any
subordination, attornment and/or Non-Disturbance Agreement provided for herein.

31. ATTORNEYS' FEES. If any Party or Broker brings an action or proceeding
involving the Premises to enforce the terms hereof or to declare rights
hereunder, the Prevailing Party (as hereafter defined) in any such proceeding,
action, or appeal thereon, shall be entitled to reasonable attorneys' fees. Such
fees may be awarded in the same suit or recovered in a separate suit, whether or
not such action or proceeding is pursued to decision or judgment. The term,
"Prevailing Party" shall include, without limitation, a Party or Broker who
substantially obtains or defeats the relief sought, as the case may be, whether
by compromise, settlement, judgment, or the abandonment by the other Party or
Broker of its claim or defense. The attorneys' fees award shall not be computed
in accordance with any court fee schedule, but shall be such as to fully
reimburse all attorneys' fees reasonably incurred. In addition, Lessor shall be
entitled to attorneys' fees, costs and expenses incurred in the preparation and
service of notices of Default and consultations in connection therewith, whether
or not a legal action is subsequently commenced in connection with such Default
or resulting Breach.

32. LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents shall
have the right to enter the Premises at any time, in the case of an emergency,
and otherwise at reasonable times after 24 hours prior notice for the purpose of
showing the same to prospective purchasers, lenders, or lessees, and making such
alterations, repairs, improvements or additions to the Premises as Lessor may
deem necessary. All such activities shall be without abatement of rent or
liability to Lessee. Lessor may at any time place on the Premises any ordinary
"For Sale" signs and Lessor may during the last six (6) months of the term
hereof place on the Premises any ordinary "For Lease" signs. Lessee may at any
time place on or about the Premises any ordinary "For Sublease" sign.

33. AUCTIONS. Lessee shall not conduct, nor permit to be conducted, any
auction upon the Premises without Lessor's prior written consent. Lessor shall
not be obligated to exercise any standard of reasonableness in determining
whether to permit an auction.

34. SIGNS. Except for ordinary "For Sublease" signs, Lessee shall not place
any sign upon the Premises without Lessor's prior written consent. All signs
must comply with all Applicable Requirements.

35. TERMINATION; MERGER. Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Breach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, that Lessor may elect to continue any one or all
existing subtenancies. Lessor's failure within ten (10) days following any such
event to elect to the contrary by written notice to the holder of any such
lesser interest, shall constitute Lessor's election to have such event
constitute the termination of such interest.

36. CONSENTS. Except as otherwise provided herein, wherever in this Lease the
consent of a Party is required to an act by or for the other Party, such consent
shall not be unreasonably withheld or delayed. Lessor's actual reasonable costs
and expenses (including but not limited to architects', attorneys', engineers'
and other consultants' fees) incurred in the consideration of, or response to, a
request by Lessee for any Lessor consent, including but not limited to consents
to an assignment, a subletting or the presence or use of a Hazardous Substance,
shall be paid by Lessee upon receipt of an invoice and supporting documentation
therefor. Lessor's consent to any act, assignment or subletting shall not
constitute an acknowledgment that no Default or Breach by Lessee of this Lease
exists, nor shall such consent be deemed a waiver of any then existing Default
or Breach, except as may be otherwise specifically stated in writing by Lessor
at the time of such consent. The failure to specify herein any particular
condition to Lessor's consent shall not preclude the imposition by Lessor at the
time of consent of such further or other conditions as are then reasonable with
reference to the particular matter for which consent is being given. In the
event that either Party disagrees with any determination made by the other
hereunder and reasonably requests the reasons for such determination, the
determining party shall furnish its reasons in writing and in reasonable detail
within ten (10) business days following such request.

38. QUIET POSSESSION. Subject to payment by Lessee of the Rent and
performance of all of the covenants, conditions and provisions on Lessee's part
to be observed and performed under this Lease. Lessee shall have quiet
possession and quiet enjoyment of the Premises during the term hereof.

grant, without the consent or joinder of Lessee, such easements, rights and
dedications that Lessor deems necessary, and to cause the recordation of parcel
maps and restrictions, so long as such easements, rights, dedications, maps and
restrictions do not unreasonably interfere with the use of the Premises by
Lessee. Lessee agrees to sign any documents reasonably requested by Lessor to
effectuate any such easement rights, dedication, map or restrictions.

43. PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise as to any
amount or sum of money to be paid by one Party to the other under the provisions
hereof, the Party against whom the obligation the money is asserted shall have
the right to make payment "under protest" and such payment shall not be regarded
as a voluntary payment and there shall survive the right on the part of said
Party to institute or recovery of such sum. If it shall be adjudged that there
was no legal obligation on the part of said Party to pay such sum or any part
thereof, said Party shall be entitled to recover such sum or so much thereof as
it was not legally required to pay.

44. AUTHORITY. If either Party hereto is acorporation, trust, limited liability
company, partnership, or similar entity, each individual executing this Lease on
behalf of such entity represents and warrants that he or she is duly authorized
to execute and deliver this Lease on its behalf. Each party shall, within thirty
(30) days after request, deliver to the other party satisfactory evidence of
such authority.

45. CONFLICT. Any conflict between the printed provisions of this Lease and
the typewritten or handwritten provisions shall be controlled by the typewritten
or handwritten provisions.

46. OFFER. Preparation of this Lease by either Party, or their agent and
submission of same to the other Party shall not be deemed an offer to lease to
the other Party. This Lease is not intended to be binding until executed and
delivered by all Parties hereto.

47. AMENDMENTS. This Lease may be modified only in writing, signed by the
Parties in interest at the time of the modification. As long as they do not
materially change Lessee's obligations hereunder, Lessee agrees to make such
reasonable non-monetary modifications to this Lease as may be reasonably
required by a Lender in connection with the obtaining of normal financing or
refinancing of the Premises.

48. MULTIPLE PARTIES. If more than one person or entity is named herein as
either Lessor or Lessee, such multiple Parties shall have joint and several
responsibility to comply with the terms of this Lease. (See Addendum Paragraph

continuing. The form of the letter of credit shall be subject to Lessor's
reasonable approval.

                  (b) Lessee shall deliver to Lessor annually during the entire
Lease term at least thirty (30) days prior to the expiration of the letter of
credit then outstanding a new one (1) year unconditional irrevocable standby
letter of credit issued by the Bank in the form previously approved by Lessor in
an amount equal to three (3) months of Base Rent at the new rate payable for the
Lease year beginning as of the following August 1st in accordance with Paragraph
50(a) above, in favor of Lessor as beneficiary, with the same provision for
payment by the Bank referred to in Paragraph 51(a) above. Failure of Lessee to
deliver to Lessor a new letter of credit which complies with the foregoing
provisions at least thirty (30) days prior to the expiration of the then
outstanding letter of credit shall constitute a breach by Lessee of this Lease,
which shall give Lessor the right to draw on the then outstanding letter of
credit.

                  (c) When Lessee's consolidated balance sheet dated as of the
end of Lessee's fiscal year prepared in accordance with generally accepted
accounting principles, certified by Lessee's independent certified public
accountants, shows that Lessee's current assets exceed Lessee's current
liabilities by more than Thirty Million Dollars ($30,000,000), the next letter
of credit delivered by Lessee to Lessor may be in an amount equal to two (2)
months of Base Rent at the new Base Rent payable for the Lease year beginning as
of the following August 1st; provided, that if any subsequent year end audited
balance sheet shows that Lessee's current assets do not exceed Lessee's current
liabilities by more than Thirty Million Dollars ($30,000,000), the next letter
of credit delivered by Lessee to Lessor shall be in an amount equal to three (3)
months of Base Rent at the Base Rent payable for the next Lease year commencing
August 1st.

                  (d) Lessor shall surrender the letter of credit to Lessee upon
the expiration or sooner termination of the lease term, provided that Lessee is
not in default hereunder. Lessee has performed all of Lessee's obligations under
this Lease, and this Lease was not terminated on account of Lessee's breach.

                  ----------------------------------------------

                  (a) Lessor shall deliver the Premises to Lessee broom clean
and free of debris on or before August 1, 1999 (the "Commencement Date") with
the improvements described in Paragraph 52(b) (the "Tenant Improvements")
completed. If the Tenant Improvements are not completed by August 1, 1999 due
solely to delays caused by Lessee which are documented by Lessor and/or the
Contractor, the Commencement Date and rent commencement shall be August 1, 1999.

                  (b) Prior to the occupancy of the Premises by Lessee, Lessor
shall cause to be constructed and completed the Tenant Improvements to the

Dymond Construction Group (the "Contractor") pursuant to an Agreement between
Lessor and the Contractor (the "Construction Contract") which shall provide for
a guaranteed maximum cost of items F, G, and H on Exhibit "B" in an amount
approved by Lessor and Lessee. Plans and specifications for the Tenant
Improvements shall be prepared by LRS Architects at Lessor's expense. The
Construction Contract and the plans and specifications for the Tenant
Improvements shall be subject to approval by Lessee, which approval shall not be
unreasonably withheld. The Construction Contract shall include a guarantee by
the Contractor against defects in workmanship or materials for one (1) year.

                  (c) The Contractor has obtained bids for the portion of the
work referred to as items F, G, and H on Exhibit "B" which is to be performed by
subcontractors. Lessor and Lessee have approved the Contractor's estimate of Two
Hundred Sixty-Seven Thousand Five Hundred Ninety-Five Dollars ($267,595) as the
cost to construct items F, G, and H. If the final bid of the Contractor for the
cost of items F, G, and H exceeds Two Hundred Sixty-Seven Thousand Five Hundred
Ninety-Five Dollars ($267,595), Lessor and Lessee have reviewed the bid and the
plans and are unable to agree upon changes to the plans to reduce the cost of
items F, G, and H to Two Hundred Sixty-Seven Thousand Five Hundred Ninety-Five
Dollars ($267,595) promptly after receipt of said bid after attempting in good
faith to do so, Lessor and Lessee shall approve the final bid of the Contractor
for items F, G, and H, and Lessee shall pay in a lump sum in cash to Lessor
promptly upon completion of the Tenant Improvements that portion of the cost of
items F, G, and H which exceeds Two Hundred Sixty-Seven Thousand Five Hundred
Ninety-Five Dollars ($267,595), in addition to the payments by Lessee to Lessor
pursuant to Paragraph 52(f) below.

                  (d) After the working drawings have been approved by Lessor
and Lessee in final form in writing as provided above, Lessee shall have the
right to request change orders to items F, G, and H. Any change order requested
by Lessee shall be subject to the prior written approval of Lessor, which
consent shall not be unreasonably withheld or delayed provided that the change
order does not increase the total improvement costs of items F, G, and H unless
Lessee agrees to pay such excess. Lessee shall not be entitled to request, and
Lessor shall not be obligated to approve, any change order which increases the
total cost of items F, G, and H to an amount which exceeds the cost previously
approved by Lessor and Lessee, unless Lessee agrees to pay such excess to Lessor
in a lump sum in cash promptly upon completion of the Tenant Improvements.

                 (e) The cost of items A through E, inclusive, on Exhibit "B"
shall be paid by Lessor.

                 (f) The cost of items F, G, and H on Exhibit "B" shall be
paid as follows:

                    (1) The initial One Hundred Sixty-Seven Thousand Five
Hundred Ninety-Five Dollars ($167,595) of the cost of items F, G, and H shall be
reimbursed by

Lessee to Lessor, with Eighty-Three Thousand Seven Hundred Ninety-Seven and
Fifty One Hundredth Dollars ($83,797.50) thereof paid in cash by Lessee to
Lessor within five (5) days after Lessor gives written notice to Lessee of
completion of the Tenant Improvements, and the remaining Eighty-Three Thousand
Seven Hundred Ninety-Seven and Fifty One Hundredth Dollars ($83,797.50) thereof
shall be evidenced by Lessee's negotiable Promissory Note in said principal
amount in form approved by Lessor delivered by Lessee to Lessor with said cash
payment of Eighty-Three Thousand Seven Hundred Ninety-Seven and Fifty One
Hundredth Dollars ($83,797.50). Said Promissory Note shall bear interest at ten
percent (10%) per annum, with principal and accrued interest all due and payable
six (6) months after the date of Lessor's notice to Lessee of the completion of
the Tenant Improvements. Default by Lessee in payment of said Note shall
constitute a default by Lessee under this Lease.

                    (2) The next One Hundred Thousand Dollars ($100,000) of the
cost of items F, G, and H initially shall be paid by Lessor to the Contractor.
Said amount shall be reimbursed by Lessee to Lessor in eighty-four (84) equal
monthly installments, plus simple interest on the unpaid principal balance at
the rate of ten percent (10%) per annum, payable by Lessee to Lessor monthly in
advance together with monthly Base Rent. Failure by Lessee to pay any
installment when due shall constitute a default by Lessee under this Lease.

                    (3) Lessee shall pay to the Lessor in cash promptly upon
completion of the Tenant Improvements that portion of the cost, if any, of items
F, G, and H which exceeds Two Hundred Sixty-Seven Thousand Five Hundred
Ninety-Five Dollars ($267,595).

                  (g) All of the Tenant Improvements which are constructed with
funds of Lessor shall become the property of Lessor. Any furnishings, trade
fixtures, equipment installed in the Premises and paid for by Lessee shall
become the property of Lessee upon installation thereof in the Premises and
Lessee shall have the right to depreciate and claim and collect investment tax
credits on any such property throughout the term of the Lease.

                  (h) Provided that no default by Lessee occurs hereunder, items
F, G, and H on Exhibit "B" shall be deemed to have been constructed with
Lessee's funds and Lessee shall be entitled to claim the depreciation deductions
(and investment tax credit, if applicable) for such items for income tax
purposes. Notwithstanding the foregoing, items F, G, and H and any other Tenant
Improvements constructed with Lessee's funds shall become a part of the realty
and shall become Lessor's property upon the expiration or sooner termination of
this Lease, except for items which Lessor and Lessee agree in writing prior to
commencement of construction may be or shall be removed by Lessee.

SILICON VALLEY BANK

LOAN AND SECURITY AGREEMENT

BORROWER:         WIRELESS, INC.
ADDRESS:          19 DAVIS DRIVE
                  BELMONT, CALIFORNIA 94002

DATE:             FEBRUARY 27, 1999

THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK, COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California 95054 and the borrower(s) named above
(jointly and severally, the "Borrower"), whose chief executive office is located
at the above address ("Borrower's Address"). The Schedule to this Agreement (the
"Schedule") shall for all purposes be deemed to be a part of this Agreement, and
the same is an integral part of this Agreement. (Definitions of certain terms
used in this Agreement are set forth in Section 8 below.)

1.       LOANS.

         1.1 LOANS. Silicon will make loans to Borrower (the "Loans"), in
amounts determined by Silicon in its sole discretion, up to the amounts (the
"Credit Limit") shown on the Schedule, provided no Default or Event of Default
has occurred and is continuing, and subject to deduction of any Reserves for
accrued interest and such other Reserves as Silicon deems proper from time to
time.

         1.2 INTEREST. All Loans and all other monetary obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement. Interest shall be payable monthly, on the last
day of the month. Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon. Regardless of the amount of
Obligations that may be outstanding from time to time, Borrower shall pay
Silicon minimum monthly interest during the term of this Agreement in the amount
set forth on the Schedule (the "Minimum Monthly Interest").

         1.3 OVERADVANCES. If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand. Without limiting Borrowers obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rote equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

         1.4 FEES. Borrower shall pay Silicon the fee(s) shown on the Schedule,
which are in addition to all interest and other sums payable to Silicon and are
not refundable.

         1.5 LETTERS OF CREDIT. At the request of Borrower, Silicon may, in its
sole discretion, issue or arrange for the issuance of letters of credit for the
account of Borrower, in each case in form and substance satisfactory to Silicon
in its sole discretion (collectively, "Letters of Credit"). The aggregate face
amount of all outstanding Letters of Credit from time to time shall not exceed
the amount shown on the Schedule (the "Letter of Credit Sublimit"), and shall be
reserved against Loans which would otherwise be available hereunder. Borrower
shall pay all bank charges (including charges of Silicon) for the issuance of
Letters of Credit, together with such additional fee as Silicon's letter of
credit department shall charge in connection with the issuance of the Letters of
Credit. Any payment by Silicon under or in connection with a Letter of Credit
shall constitute a Loan hereunder on the date such payment is made. Each Letter
of Credit shall have an expiry date no later than thirty days prior to the
Maturity Date. Borrower hereby agrees to indemnify, save, and hold Silicon
harmless from any loss, cost, expense, or liability, including payments made by
Silicon expenses, and reasonable attorneys' fees incurred by Silicon arising out
of or in connection with any Letters of Credit. Borrower agrees to be bound by
the regulations and interpretations of the issuer of any Letters of Credit
guarantied by Silicon and opened for Borrower's account or by Silicon's
interpretations of any Letter of Credit issued by Silicon for Borrower's
account, and Borrower understands and agrees that Silicon shall not be liable
for any error, negligence, or mistake, whether of omission or commission, in
following Borrower's instructions or those contained in the Letters of Credit
or any modifications,
<PAGE>

amendments, or supplements thereto. Borrower understands that Letters of Credit
may require Silicon to indemnify the issuing bank for certain costs or
liabilities arising out of claims by Borrower against such issuing bank.
Borrower hereby agrees to indemnify and hold Silicon harmless with respect to
any loss, cost, expense, or liability incurred by Silicon under any Letter of
Credit as a result of Silicon's indemnification of any such issuing bank. The
provisions of this Loan Agreement, as it pertains to Letters of Credit, and any
other present or future documents or agreements between Borrower and Silicon
relating to Letters of Credit are cumulative.

2.       SECURITY INTEREST.

         2.1 SECURITY INTEREST. To secure the payment and performance of all of
the Obligations when due, Borrower hereby grants to Silicon a security interest
in all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located (collectively, the "Collateral"): All Inventory,
Equipment, Receivables, and General Intangibles, including, without limitation,
all of Borrower's Deposit Accounts, and all money, and all property now or at
any time in the future in Silicon's possession (including claims and credit
balances), and all proceeds (including proceeds of any insurance policies,
proceeds of proceeds and claims against third parties), all products and all
books and records related to any of the foregoing (all of the foregoing,
together with all other property in which Silicon may now or in the future be
granted a lien or security, interest, is referred to herein, collectively, as
the "Collateral").

3.       REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

         In order to induce Silicon to enter into this Agreement and to make
Loans, Borrower represents and warrants to Silicon as follows, and Borrower
covenants that the following representations will continue to be true, and that
Borrower will at all times comply with all of the following covenants:

         3.1 CORPORATE EXISTENCE AND AUTHORITY. Borrower, if a corporation, is
and will continue to be, duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation. Borrower is and will
continue to be qualified and licensed to do business in all jurisdictions in
which any failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (i) have been duly and validly authorized, (ii)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), and (iii) do not violate Borrower's articles or certificate
of incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property.

         3.2 NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon 30 days prior written notice before changing its
name or doing business under any other name. Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

         3.3 PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth
in the heading to this Agreement is Borrower's chief executive office. In
addition, Borrower has places of business and Collateral is located only at the
locations set forth on the Schedule. Borrower will give Silicon at least 30 days
prior written notice before opening any additional place of business, changing
its chief executive office, or moving any of the Collateral to a location other
than Borrower's Address or one of the locations set forth on the Schedule.

         3.4 TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at
all times in the future be, the sole owner of all the Collateral, except for
items of Equipment which are leased by Borrower. The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens. Silicon now has,
and will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Silicon and the Collateral against all claims
of others. None of the Collateral now is or will be affixed to any real property
in such a manner, or with such intent, as to become a fixture. Borrower is not
and will not become a lessee under any real property lease pursuant to which the
lessor may obtain any rights in any of the Collateral and no such lease now
prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's
right to remove any Collateral from the leased premises. Whenever any Collateral
is located upon premises in which any third party has an interest (whether as
owner, mortgagee beneficiary under a deed of trust, lien or otherwise), Borrower
shall, whenever requested by Silicon, use its best efforts to cause such third
party to execute and deliver to Silicon, in form acceptable to Silicon, such
waivers and subordinations as Silicon shall specify, so as to ensure that
Silicon's rights in the Collateral are, and will continue to be, superior to the
rights of any such third party. Borrower will keep in full force and effect, and
will comply with all the terms of, any lease of real property where any of the
Collateral now or in the future may be located.

         3.5 MAINTENANCE OF COLLATERAL. Borrower will maintain the Collateral in
good working condition, and Borrower will not use the Collateral for any
unlawful purpose. Borrower will immediately advise Silicon in writing of any
material loss or damage to the Collateral.
<PAGE>

         3.6 BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

         3.7 FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial
statements now or in the future delivered to Silicon have been, and will be,
prepared in conformity with generally accepted accounting principles and now and
in the future will completely and accurately reflect the financial condition of
Borrower, at the times and for the periods therein stated. Between the last date
covered by any such statement provided to Silicon and the date hereof, there has
been no material adverse change in the financial condition or business of
Borrower. Borrower is now and will continue to be solvent.

         3.8 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state and local law, and Borrower has timely paid, and will
timely pay, all foreign, federal, state and local taxes, assessments, deposits
and contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrowers obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. Borrower is
unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.
Borrower shall, at all times, utilize the services of an outside payroll service
providing for the automatic deposit of all payroll taxes payable by Borrower.

         3.9 COMPLIANCE WITH LAW. Borrower has complied, and will comply, in all
material respects, with all provisions of all foreign, federal, state and local
laws and regulations relating to Borrower, including, but not limited to, those
relating to Borrower's ownership of real or personal property, the conduct and
licensing of Borrower's business, and all environmental matters.

         3.10 LITIGATION. Except as disclosed in the Schedule, there is no
claim, suit, litigation, proceeding or investigation pending or (to best of
Borrower's knowledge) threatened by or against or affecting Borrower in any
court or before any governmental agency (or any basis therefor known to
Borrower) which may result, either separately or in the aggregate, in any
material adverse change in the financial condition or business of Borrower, or
in any material impairment in the ability of Borrower to carry on its business
in substantially the same manner as it is now being conducted. Borrower will
promptly inform Silicon in writing, of any claim, proceeding, litigation or
investigation in the future threatened or instituted by or against Borrower
involving any single claim of $50,000 or more, or involving $100,000 or more in
the aggregate.

deliver to Silicon transaction reports and loan requests, schedules and
assignments of all Receivables, and schedules of collections, all on Silicon's
standard forms; provided, however, that Borrower's failure to execute and

rights in all of Borrower's Receivables, nor shall Silicon's failure to advance
or lend against a specific Receivable affect or limit Silicon's security
interest and other rights therein. Loan requests received after 12:00 Noon will

claims relating to Receivables. Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in full,

credit Borrower's Loan account with only the net amounts received by Silicon in
payment of any Receivables.

continuing, if any Account Debtor returns any Inventory to Borrower in the
ordinary course of its business, Borrower shall promptly determine the reason

         4.9 NO LIABILITY. Silicon shall not under any circumstances be
responsible or liable for any shortage or discrepancy in, damage to, or loss or

personal property Collateral and carry such
<PAGE>

other business insurance, with insurers reasonably acceptable to Silicon, in
such form and amounts as Silicon may reasonably require, and Borrower shall
provide evidence of such insurance to Silicon, so that Silicon is satisfied that

on one Business Day's notice, Silicon, or its agents, shall have the right to
inspect the Collateral, and the right to audit and copy Borrower's books and
records. Silicon shall take reasonable steps to keep confidential all
information obtained in any such inspection or audit, but Silicon shall have the
right to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $500 per person per day (or such higher amount as shall represent
Silicon's then current standard charge for the same), plus reasonable out of
pocket expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, without first obtaining Silicon's
written consent, which may be conditioned upon such accounting firm, service
bureau or other third party agreeing to give Silicon the same rights with
respect to access to books and records and related rights as Silicon has under
this Loan Agreement. Borrower waives the benefit of any accountant-client
privilege or other evidentiary privilege precluding or limiting the disclosure,
divulgence or delivery, of any of its books and records (except that Borrower
does not waive any attorney-client privilege).

maturity date set forth on the Schedule (the "Maturity, Date"); provided that
the Maturity Date shall automatically be extended, and this Agreement shall

year each unless one party gives written notice to the other, not less than
sixty days prior to the next Maturity Date, that such party elects to terminate
this Agreement effective on the next Maturity Date.
<PAGE>

Maturity Date as follows: (i) by Borrower, effective three Business Days after
written notice of termination is given to Silicon: or (ii) by Silicon at any
time after the occurrence of an Event of Default, without notice, effective

shall be due and payable on the effective date of termination and thereafter
shall bear interest at a rate equal to the highest rate applicable to any of the
Obligations.

         6.2 PAYMENT OF OBLIGATIONS. On the Maturity Date or on any earlier

Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Silicon, Silicon may, in its sole discretion, refuse to make any further Loans
after termination. No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower
termination statements, requests for re-conveyances and such other documents as

or security, relating thereto required by any statute, court role or otherwise

interest at a rate equal to the highest interest rate applicable to any of the
Obligations. Without limiting any of Silicon's rights and remedies from and

the Obligations shall be increased by an additional four percent per annum.

         7.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and

Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to

newspaper of general circulation in the county where the sale is to be

of its employees, attorneys or agents) at any time, at its option, but without
obligation, with or without notice to Borrower, and at Borrower's expense, to do
any or all of the following, in Borrower's name or otherwise, but Silicon agrees
to exercise the following powers in a commercially reasonable manner: (a)
Execute on behalf of Borrower any documents that Silicon may, in its sole

interest in the Collateral, or in order to exercise a right of Borrower or
Silicon, or in order to fully consummate all the transactions contemplated under
this Agreement and all other present and future agreements; (b) Execute on
behalf of Borrower any document exercising, transferring or assigning any option
to purchase, sell or otherwise dispose of or to lease (as lessor or lessee) any

relating to any Receivable, any draft against any Account Debtor and any notice

of mechanic's, materialman's or other lien; (d) Take control in any manner of
any cash or non-cash items of payment or proceeds of Collateral; endorse the

insurance claim that relates to any of the Collateral and obtain payment

Agreement; and (k) Take any action or pay any sum required of Borrower pursuant
to this Agreement and any other present or future agreements. Any and all
reasonable sums paid and any and all reasonable costs, expenses, liabilities,
obligations and attorneys' fees incurred by Silicon with respect to the
foregoing shall be added to and become part of the Obligations, shall be payable
on demand, and shall bear interest at a rate equal to the highest interest rate
applicable to any of the Obligations. In no event shall Silicon's rights under
the foregoing power of attorney or any of Silicon's other rights under this
Agreement be deemed to indicate that Silicon is in control of the business,
management or properties of Borrower.

         7.5 APPLICATION OF PROCEEDS. All proceeds realized as the result of any
sale of the Collateral shall be applied by Silicon first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon in the exercise of its rights under this Agreement, second to the
interest due upon any of the Obligations, and third to the principal of the
Obligations, in such order as Silicon shall determine in its sole discretion.
Any surplus shall be paid to Borrower or other persons legally entitled thereto;
Borrower shall remain liable to Silicon for any deficiency. If, Silicon, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

         7.6 REMEDIES CUMULATIVE. In addition to the rights and remedies set
forth in this Agreement, Silicon shall have all the other rights and remedies
accorded a secured party under the California Uniform Commercial Code and under
all other applicable laws, and under any other instrument or agreement now or in
the future entered into between Silicon and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its or remedies shall not be deemed an election, nor
bar Silicon from subsequent exercise or partial exercise of any other rights or
remedies. The failure or delay of Silicon to exercise any rights or remedies
shall not operate as a waiver thereof, but all rights and remedies shall
continue in full force and effect until all of the Obligations have been fully
paid and performed.

checks, wire transfers and other items of payment received by Silicon (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by Silicon on account of the Obligations three Business Days after

to Silicon in its sole discretion, and Silicon may charge Borrower's loan
account for the amount of any item of payment which is returned to Silicon
unpaid.

         9.2 APPLICATION OF PAYMENTS. All payments with respect to the
Obligations may be applied, and in Silicon's sole discretion reversed and
reapplied, to the Obligations, in such order and manner as Silicon shall
determine in its sole discretion.

PARTIES IN CONNECTION HEREWITH.

         9.8 WAIVERS. The failure of Silicon at any time or times to require

other present or future agreement between Borrower and Silicon shall not waive
or diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future

waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Silicon.

         9.11 TIME OF ESSENCE.  Time is of the essence in the performance by
Borrower of each and every obligation under this Agreement.

         9.12 ATTORNEYS FEES AND COSTS. Borrower shall reimburse Silicon for
all reasonable attorneys' fees and all filing, recording, search, title
insurance, appraisal, audit, and other reasonable costs incurred by Silicon,
pursuant to, or in connection with, or relating to this Agreement (whether or

other predicated on a breach of this Agreement, the prevailing party in such
action shall be entitled to recover its reasonable costs and attorneys' fees,
including (but not limited to) reasonable attorneys' fees and costs incurred in
the enforcement of, execution upon or defense of any order, decree, award or
judgment. All attorneys' fees and costs to which Silicon may be entitled

                                            the best rate available at Silicon.

                                            Rate.

Agreement) being executed concurrently with this Agreement. If between the date
hereof and October 8, 1999, Borrower does not receive cash proceeds of at least
$7,000,000 in consideration of Borrower's issuance of Series E Preferred stock,
(i) Borrower shall provide Silicon with five-year warranty to purchase an
additional 8,000 shares of Borrower's Series E Preferred stock at $1.25 per
share (the "Additional Series E Warrants"), on terms acceptable to Silicon, and
(ii) the strike price of the Initial Series E Warrants shall be amended from

Exchange Commission.

                  1.2    COMPANY REGISTRATION.

                         (a)      REGISTRATION.  If at any time or from time to
time, the Company shall determine to register any of its securities, for its own
account or the account of any of its shareholders, other than a registration on
Form S-1 or S-8 relating solely to employee stock option or purchase plans, or a
registration on Form S-4 relating solely to an SEC Rule 145 transaction, or a
registration on any other form (other than Form S-1, S-2, S-3 or S-18, or their
successor forms) or any successor to such forms, which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities, the Company
will:

                                  (i)    promptly  give to  each Holder  written
notice thereof (which shall include a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under the applicable blue
sky or other state securities laws); and

                                  (ii)   include in such registration (and
compliance), and in any underwriting involved therein, all the Registrable
Securities specified in a written request or requests, made within 30 days after
receipt of such written notice from the Company, by any Holder or Holders,
except as set forth in subsection 1.2(b) below.

                         (b)      UNDERWRITING. If the registration of which the
Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written
notice given pursuant to subsection 1.2(a)(i). In such event the right of any
Holder to registration pursuant to this subsection 1.2 shall be conditioned upon
such Holder's participation in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting to the extent provided
herein. All Holders proposing to distribute their securities through such
underwriting shall (together with the Company and the other shareholders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company.

                  1.3    EXPENSES OF REGISTRATION. All expenses incurred in
connection with any registration, qualification or compliance pursuant to this
Section 1 including without limitation, all registration, filing and
qualification fees, printing expenses, fees and disbursements of counsel for the
Company and expenses of any special audits incidental to or required by such
registration, shall be borne by the Company except the Company shall not be
required to pay underwriters' fees, discounts or commissions relating to
Registrable Securities. All expenses of any registered offering not otherwise
borne by the Company shall be borne pro rata among the Holders participating in
the offering and the Company.

                  1.4    REGISTRATION PROCEDURES. In the case of each
registration, qualification or compliance effected by the Company pursuant to
this Registration Rights Agreement, the Company will keep each Holder
participating therein advised in writing as to the initiation of each
registration, qualification and compliance and as to the completion thereof.
Except as otherwise provided in subsection 1.3, at its expense the Company will:
<PAGE>

                         (a)      Prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use its best efforts
to cause such registration statement to become effective, and, upon the request
of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective for up to 120 days.

                         (b)      Prepare and file with the SEC such amendments
and supplement to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

                         (c)      Furnish to the Holders such numbers of copies
of a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                         (d)      Use its best efforts to register and qualify
the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders, provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such state or jurisdictions.

                         (e)      In the event of any underwritten public
offering, enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such
offering. Each Holder participating in such underwriting shall also enter into
and perform its obligations under such an agreement.

                         (f)      Notify each Holder of Registrable  Securities
covered by such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Securities Act or the happening of
any event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstance then
existing.

                  1.5    INDEMNIFICATION.

                         (a)      The  Company  will  indemnify  each  Holder of
Registrable Securities and each of its officers, directors and partners, and
each person controlling such Holder, with respect to which such registration,
qualification or compliance has been effected pursuant to this Rights Agreement,
and each underwriter, if any, and each person who controls any underwriter of
the Registrable Securities held by or issuable to such Holder, against all
claims, losses, expenses, damages and liabilities (or actions in respect
thereto) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any prospectus, offering circular or
other document (including any related registration statement, notification or
the like) incident to any such registration, qualification or compliance, or
based on
<PAGE>

any  omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statement therein not misleading,
or any violation or alleged violation by the Company of the Securities Act, the
Securities Exchange Act of 1934, as amended ("Exchange Act") or any state
securities law applicable to the Company or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any such state law and relating to
action or inaction required of the Company in connection with any such
registration, qualification of compliance, and will reimburse each such Holder,
each of its officers, directors and partners, and each person controlling such
Holder, each such underwriter and each person who controls any such underwriter,
within a reasonable amount of time after incurred for any reasonable legal and
any other expenses incurred in connection with investigating, defending or
settling any such claim, loss, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection 1.5(a) shall not apply
to amounts paid in settlement of any such claim, loss, damage, liability, or
action if such settlement is effected without the consent of the Company (which
consent shall not be unreasonably withheld); and provided further, that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage or liability arises out of or is based on any untrue statement or
omission based upon written information furnished to the Company by an
instrument duly executed by such Holder or underwriter specifically for use
therein.

                         (b)      Each Holder will, if Registrable Securities
held by or issuable to such Holder are included in the securities, as to which
such registration, qualification or compliance is being effected, indemnify the
Company, each of its directors and officers, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company within the meaning of the Securities Act, and each other
such Holder, each of its officers, directors and partners and each person
controlling such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement, prospectus, offering circular or other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company, such Holders, such directors,
officers, partners, persons or underwriters for any reasonable legal or any
other expenses incurred in connection with investigating, defending or settling
any such claim, loss, damage, liability or action, in each case to the extent,
but only to the extent, that such untrue statements (or alleged untrue
statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and
in conformity with written information furnished to the Company by an instrument
duly executed by such Holder specifically for use therein; provided, however,
that the indemnity agreement contained in this subsection 1.5(b) shall not apply
to amounts paid in settlement of any such claim, loss, damage, liability or
action if such settlement is effected without the consent of the Holder, (which
consent shall not be unreasonably withheld); and provided further, that the
total amount for which any Holder shall be liable under this subsection 1.5(b)
shall not in any event exceed the aggregate proceeds received by such Holder
from the sale of Registrable Securities held by such Holder in such
registration.
<PAGE>

                         (c)      Each party entitled to indemnification under
this subsection 1.5 (the "Indemnified Party") shall give notice to the party
required to provide indemnification (the "Indemnifying Party") promptly after
such Indemnified Party has actual knowledge of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the defense of
any such claim or any litigation resulting therefrom; provided that counsel for
the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall not
be unreasonably withheld), and the Indemnified Party may participate in such
defense at such party's expense; and provided further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations hereunder, unless such failure resulted in
prejudice to the Indemnifying Party; and provided further, that an Indemnified
Party (together with all other Indemnified Parties which may be represented
without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the Indemnifying Party, if
representation of such Indemnified Party by the counsel retained by the
Indemnifying Party would be inappropriate due to actual or potential differing
interests between such Indemnified Party and any other party represented by such
counsel in such proceeding. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation.

                  1.6    INFORMATION BY HOLDER. Any Holder or Holders of
Registrable Securities included in any registration shall promptly furnish to
the Company such information regarding such Holder or Holders and the
distribution proposed by such Holder or Holders as the Company may request in
writing and as shall be required in connection with any registration,
qualification or compliance referred to herein.

                  1.7    RULE 144 REPORTING. With a view to making available to
Holders the benefits of certain rules and regulations of the SEC which may
permit the sale of the Registrable Securities to the public without
registration, the Company agrees at all times to:

                         (a)      make and keep public information  available,
as those terms are understood and defined in SEC Rule 144, after 90 days after
the effective date of the first registration filed by the Company for an
offering of its securities to the general public;

                         (b)      file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements); and

                         (c)      so long as a Holder owns any Registrable
Securities, to furnish to such Holder forthwith upon request a written statement
by the Company as to its compliance with the reporting requirements of said Rule
144 (at any time after 90 days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of
<PAGE>

the  Company, and such other reports and  documents so filed by the Company as
the Holder may reasonably request in complying with any rule or regulation of
the SEC allowing the Holder to sell any such securities without registration.

                  1.8    TRANSFER OF REGISTRATION RIGHTS. Holders' rights to
cause the Company to register their securities and keep information available,
granted to them by the Company under subsections 1.2 and 1.7 may be assigned to
a transferee or assignee of a Holder's Registrable Securities not sold to the
public, provided, that the Company is given written notice by such Holder at the
time of or within a reasonable time after said transfer, stating the name and
address of said transferee or assignee and identifying the securities with
respect to which such registration rights are being assigned. The Company may
prohibit the transfer of any Holders' rights under this subsection 1.8 to any
proposed transferee or assignee who the Company reasonably believes is a
competitor of the Company.

         2.       GENERAL.

                  2.1    WAIVERS AND AMENDMENTS. With the written consent of the
record or beneficial holders of at least a majority of the Registrable
Securities, the obligations of the Company and the rights of the Holders of the
Registrable Securities under this agreement may be waived (either generally or
in a particular instance, either retroactively or prospectively, and either for
a specified period of time or indefinitely), and with the same consent the
Company, when authorized by resolution of its Board of Directors, may enter into
a supplementary agreement for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement;
provided, however, that no such modification, amendment or waiver shall reduce
the aforesaid percentage of Registrable Securities without the consent of all of
the Holders of the Registrable Securities. Upon the effectuation of each such
waiver, consent, agreement of amendment or modification, the Company shall
promptly give written notice thereof to the record holders of the Registrable
Securities who have not previously consented thereto in writing. This Agreement
or any provision hereof may be changed, waived, discharged, or terminated only
by a statement in writing signed by the party against which enforcement of the
change, waiver, discharge or termination is sought, except to the extent
provided in this subsection 2.1.

                  2.2    GOVERNING LAW. This Agreement shall be governed in all
respects by the laws of the State of California as such laws are applied to
agreements between California residents entered into and to be performed
entirely within California.

                  2.3    SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
the parties hereto.

                  2.4    ENTIRE AGREEMENT. Except as set forth below, this
Agreement and the other documents delivered pursuant hereto constitute the full
and entire understanding and agreement between the parties with regard to the
subjects hereof and thereof.
<PAGE>

                  2.5    NOTICES, ETC. All notices and other communications
required or permitted hereunder shall be in writing and shall be mailed by first
class mail, postage prepaid, certified or registered mail, return receipt
requested, addressed (a) if to Holder, at such Holder's address as set forth
below, or at such other address as such Holder shall have furnished to the
Company in writing, or (b) if to the Company, at the Company's address set forth
below, or at such other address as the Company shall have furnished to the
Holder in writing.

                  2.6    SEVERABILITY. In case any provision of this Agreement
shall be invalid, illegal, or unenforceable, the validity, legality and
enforceability of the remaining provisions of this Agreement or any provision of
the other Agreements shall not in any way be affected or impaired thereby,

                  2.7    TITLES AND SUBTITLES. The titles of the sections  and
subsections of this Agreement are for  convenience of reference only and are not
to be considered in construing this Agreement.

                  2.8    COUNTERPARTS.  This  Agreement may be  executed  in any
number of counterparts, each of which shall be an original, but all of which
together shall constitute one instrument.

                    Upon Silicon's receipt of evidence, satisfactory to Silicon

    (Section 1.2):  A rate equal to the "Prime Rate" in effect from time to

                    the basis of a 360-day year for the actual number of days
                    elapsed. "Prime Rate" means the rate announced from time to
                    time by Silicon as its "prime rate;" it is a base rate upon
                    which other rates charged by Silicon are based, and it is
                    not necessarily the best rate available at Silicon. The

          9.3.3.5 MAINTENANCE. The parties will equally share all maintenance
and similar fees imposed by any authority *. WI may invoice TRW for such fees
quarterly in advance, and TRW will promptly pay such invoices. WI will then
promptly pay any such maintenance and similar fees to the appropriate authority.

9.4  CONTINUED PATENTING EXPENSES

     No party is obligated to incur any costs for maintaining any Program Office
Patent. If a party decides that it no longer desires to continue to prosecute,
obtain or maintain a Patent in a particular country, then it will assign its
ownership rights to the Patent in that country to the other party, but will
retain a worldwide, non-exclusive, royalty-free, fully paid up, perpetual right
and license, without the right to grant sublicenses, under any Patent issuing to
make, have made, manufacture, import, use and Sell products covered by such
Spitfire Invention or Program Office Invention, as the case may be, the license

notice of such office actions received, and the other party shall have complete
authority and control to prosecute the patent application.

9.5  ENFORCEMENT

     No party is obligated to incur any costs for policing any Program Office
Patent or Spitfire Patent, or for enforcing any Program Office Patent or
Spitfire Patent against any third party for infringement. Either party may seek
to enforce a Spitfire Patent or Program Office Patent to which it retains an
ownership interest, and the other party will

evidencing Stock upon delivery to WI of an opinion by counsel, reasonably
satisfactory to WI, that a registration statement under the Act is at that time

                                       26
<PAGE>

amended, and neither WI nor any authorized agent acting on its behalf will take
any action hereafter that would cause the loss of such exemption.

          (j) Disclosure. WI has fully provided the TRW with all the information
that it has requested for deciding whether accept the Common Stock as
consideration hereunder and all information that WI believes is reasonably
necessary to enable the TRW to make such decision. Neither this Agreement nor
any other statements or certificates made or delivered in connection herewith or
therewith contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements herein or therein not misleading.

          (k) Corporate Documents. Except for amendments necessary to satisfy
representations and warranties or conditions contained herein (the form of which
amendments has been approved by TRW), the Articles and Bylaws of WI are in the
form previously provided to TRW. The minute books of WI provided to TRW contain
a complete summary of all meetings of directors and shareholders since the time

          (l) Proprietary Information and Employee Stock Purchase Agreements.
Each employee, officer and consultant of WI has executed a Proprietary
Information and Inventions Agreement in the form provided to special counsel to

officers or consultants are in violation thereof, and WI will use its best
efforts to prevent any such violation.

          (m) Patents and Trademarks. WI has sufficient title and ownership of
all patents, trademarks, service marks, trade names, copyrights, trade secrets,
information, proprietary rights and processes necessary for its business as now
conducted and as proposed to be conducted without any conflict with or
infringement of the rights of others. There are no outstanding options,
licenses, or agreements of any kind relating to the foregoing, nor is WI bound
by or a party to any options, licenses or agreements of any kind with respect to
the patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information, proprietary rights and processes of any other person or
entity. WI has not received any communications alleging that WI has violated or,
by conducting its business as presently conducted or proposed to be conducted,
would violate any of the patents, trademarks, service marks, trade names,
copyrights or trade secrets or other proprietary rights of any other person or
entity, or that any intellectual property owned by WI is invalid or
unenforceable. WI is not aware that any of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of his or her best
efforts to promote the interests of WI or that would conflict with WI's business
as presently conducted or proposed to be conducted. Neither the execution nor
delivery of this Agreement, nor the carrying on of WI's business by the
employees of WI, nor the conduct of WI's business as presently conducted or
proposed to be conducted, will, to the best of WI's knowledge, conflict with or
result in a breach of the

                                       27
<PAGE>

terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any of such employees is now obligated. WI

its employees (or people it currently intends to hire) made prior to their
employment by WI.

          (n) Compliance with Other Instruments.

               (a) WI is not in violation or default of any provision of its
Articles or Bylaws, or of any instrument, judgment, order, writ, decree or
contract to which it is a party or by which it is bound, or, to the best of its
knowledge, of any provision of any federal or state statute, rule or regulation
applicable to WI. The

execution, delivery and performance of this Agreement and TRW' Rights Agreement,
and the consummation of the transactions contemplated hereby and thereby will
not result in any such violation or be in conflict with or constitute, with or
without the passage of time and giving of notice, either a default under any
such provision, instrument, judgment, order, writ, decree or contract or an
event that results in the creation of any lien, charge or encumbrance upon any
assets of WI or the suspension, revocation, impairment, forfeiture, or
nonrenewal of any material permit, license, authorization, or approval
applicable to WI, its business or operations or any of its assets or properties.

               (b) To the knowledge of WI, WI has avoided every condition, and
has not performed any act, the occurrence of which would result in WI's loss of
any right granted under any license, distribution or other agreement.

directors, affiliates, or any affiliate thereof.

               (b) There are no agreements, understandings, instruments,
contracts, proposed transactions, judgments, orders, writs or decrees to which

or made any distribution upon or with respect to any class or series of its
capital stock, (ii) incurred any indebtedness for money borrowed or any other
liabilities individually in excess of $20,000 or, in the case of indebtedness
and/or liabilities individually less than $20,000, in excess of $75,000 in the
aggregate, (iii) made any loans or advances to or

                                       28
<PAGE>

guaranteed any liabilities of any person, other than ordinary advances to
employees or consultants for travel expenses, or (iv) sold, exchanged or
otherwise disposed of any of its assets or rights, other than the sale of its
inventory in the ordinary course of business.

               (d) For the purposes of subsections (b) and (c) above, all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same person or entity (including persons
or entities WI has reason to believe are affiliated therewith) shall be
aggregated for the purpose of meeting the individual minimum dollar amounts of
such subsections.

               (e) WI has not engaged in the past three (3) months in any
discussion (i) with any representative of any corporation or corporations
regarding the consolidation or merger of WI with or into any such corporation or
corporations, (ii) with any corporation, partnership, association or other
business entity or any individual regarding the sale, conveyance or disposition
of all or substantially all of the assets of WI or a transaction or series of
related transactions in which more than fifty percent (50%) of the voting power
of WI is disposed of, or (iii) regarding any other form of acquisition,
liquidation, dissolution or winding up of WI.

               (f) WI is not a party to and is not bound by any contract,
agreement or instrument, or subject to any restrictions under its Articles or
Bylaws that presently adversely affects its business as now conducted.

          (p) Related-Party Transactions. No employee, officer, director or
stockholder of WI or member of his or her immediate family is indebted to WI,
nor is WI indebted (or comitted to make loans or extend or guarantee credit) to
any of them. To the best of WI's knowledge, none of such persons has any direct
or indirect ownership interest in any firm or corporation with which WI is
affiliated or with which WI has a business relationship, or any firm or
corporation that competes with WI, except that employees, officers, or directors
of WI and members of their immediate families may own stock in publicly traded
companies that compete with WI. No member of the immediate family of any officer
or director of WI is directly or indirectly interested in any material contract
with WI.

          (q) Permits. WI has all franchises, permits, licenses, and any similar
authority necessary for the conduct of its business as now being conducted by
it, the lack of which could materially and adversely affect the business,
properties, prospects, results of operations or financial condition of WI, and
WI believes it can obtain, without undue burden or expense, any similar
authority for the conduct of its business as planned to be conducted. WI is not
in default in any material respect under any of such franchises, permits,
licenses, or other similar authority.

          (r) Environmental and Safety Laws. To the best of its knowledge, WI is
not in violation of any applicable statute, law or regulation relating to the
environment or occupational health and safety, and to the best of its knowledge,
no material expenditures are or will be required in order to comply with any
such existing statute, law or regulation.

<PAGE>

          (s) Manufacturing and Marketing Rights. WI has not granted rights to

WI has not granted or agreed to grant any registration rights, including
piggyback rights, to any person or entity.

          (u) Title to Property and Assets. WI owns its property and assets free
and clear of all mortgages, liens, loans and encumbrances, except such
encumbrances and liens that arise in the ordinary course of business and do not
materially impair WI's ownership or use of such property or assets. With respect
to the property and assets it leases, WI is in compliance with such leases and,
to the best of its knowledge, holds a valid leasehold interest free of any
liens, claims or encumbrances.

          (v) Financial Statements.

               (a) WI has delivered to TRW its unaudited financial statements
(balance sheet and profit and loss statement, statement of stockholders' equity
and statement of cash flows, including notes thereto) at December 31, 1998 and
for the fiscal year then ended, and its unaudited financial statements (balance
sheet and profit and loss statement) as at and for the nine month period ended
September 30, 1999 (the "Financial Statements") (i) the pro forma consolidated
balance sheet of WI and its Subsidiaries as at September 30, 1999 and the pro
forma combined historical income statements dated September 30, 1999, each such
balance sheets and income statements taking into account all transactions
contemplated hereby and by the Related Agreements, such balance sheet and income
statements being attached hereto as Schedule 2.22(a)(ii); and (iii) the
projections of the future performance of WI and its Subsidiaries for the
five-year period following the Closing Date, on a consolidated basis, including
income, net profits, and cash flows, as attached hereto as Schedule 2.22(a)(iii)
(the "Projections"). The Financial Statements have been prepared in accordance
with generally accepted accounting principles applied on a consistent basis
throughout the periods indicated and with each other, except that unaudited
Financial Statements may not contain all footnotes required by generally
accepted accounting principles applicable to audited annual financial
statements. The Financial Statements fairly present the financial condition and
operating results of WI as of the dates, and for the periods, indicated therein,
subject in the case of unaudited Financial Statements to normal year-end audit
adjustments. Except as set forth in the Financial Statements, WI has no material
liabilities, contingent or otherwise, other than (i) liabilities incurred in the
ordinary course of business subsequent to September 30, 1999 and (ii)
obligations under contracts and commitments incurred in the ordinary course of
business and not required under generally accepted accounting principles to be
reflected in the Financial Statements, which, in both cases, individually or in
the aggregate, are not material to the financial condition or operating results
of WI. Except as disclosed in the Financial Statements, WI is not a guarantor or
indemnitor of any indebtedness of any other

                                       30
<PAGE>

person, firm or corporation. WI maintains and will continue to maintain a
standard system of accounting established and administered in accordance with
generally accepted accounting principles.

               (b) The pro forma consolidated balance sheet of WI and its
Subsidiaries and the pro forma consolidated income statements referred to in
Section 2.22(a)(ii) have been prepared by management of WI on a reasonable
basis, taking into consideration the effect of the transactions contemplated
hereby and by the Related Agreements, and WI is not aware of any fact which
casts any doubt on the accuracy or completeness thereof. After giving effect to
the transactions contemplated hereby and by the Related Agreements, WI and its
Subsidiaries will have no material liabilities, contingent or otherwise, which
are not referred to in such balance sheet or in the notes thereto.

               (c) The Projections constitute a reasonable basis for the
assessment of the future performance of WI and its Subsidiaries, on a
consolidated basis, during the periods indicated therein, and all material
assumptions used in the preparation of the Projections are set forth in the
notes thereto.

          (w) Changes. Since September 30, 1999 there has not been:

               (a) any change in the assets, liabilities, financial condition or
operating results of WI from that reflected in the Financial Statements, except
changes in the ordinary course of business that have not been, in the aggregate,
materially adverse;

               (b) any damage, destruction or loss, whether or not covered by
insurance, materially and adversely affecting the assets, properties, financial
condition, operating results, prospects or business of WI (as such business is
presently conducted and as it is proposed to be conducted);

               (c) any waiver by WI of a material right or of a material debt
owed to it;

               (d) any satisfaction or discharge of any lien, claim or

business and that is not material to the assets, properties, financial
condition, operating results or business of WI (as such business is presently
conducted and as it is proposed to be conducted);

               (e) any material change or amendment to a material contract or
arrangement by which WI or any of its assets or properties is bound or subject;

               (f) any change in any material compensation arrangement or
agreement with any employee;

                                       31
<PAGE>

               (g) any sale, assignment or transfer of any patents, trademarks,
copyrights, trade secrets or other intangible assets;

               (h) any resignation or termination of employment of any key
officer of WI; and WI, to the best of its knowledge, does not know of the
impending resignation or termination of employment of any such officer;

               (i) receipt of notice that there has been a loss of, or material
order cancellation by, any customer of WI;

               (j) any mortgage, pledge, transfer of a security interest in, or
lien, created by WI, with respect to any of its material properties or assets,
except liens for taxes not yet due or payable;

               (k) any loans or guarantees made by WI to or for the benefit of

               (m) to the best of WI's knowledge, any other event or condition
of any character that might materially and adversely affect the assets,
properties, financial condition, operating results or business of WI (as such
business is presently conducted and as it is proposed to be conducted); or

               (n) any agreement or commitment by WI to do any of the things
described in the Section 2.24.

          (x) Employee Benefit Plans. WI does not have any Employee Benefit Plan
as defined in the Employee Retirement Income Security Act of 1974.

          (y) Tax Returns, Payments and Elections. WI has filed all tax returns
and reports as required by law. These returns and reports are true and correct
in all material respects. WI has timely paid all taxes and other assessments
due, except those contested by it in good faith that are listed in the Schedule
of Exceptions. The provision for taxes of WI as shown in the Financial
Statements is adequate for taxes due or accrued as of the date thereof. WI has
not elected pursuant to the Internal Revenue Code of 1986, as amended (the
"Code"), to be treated as a Subchapter S corporation or a collapsible
corporation pursuant to Section 1362(a) or Section 341(f) of the Code, nor has
it made any other elections pursuant to the Code (other than elections that
relate solely to methods of accounting, depreciation or amortization) that would
have a material effect on WI, its financial condition, its business as presently
conducted or proposed to be conducted or any of its properties or material
assets. WI has never had any tax deficiency proposed or assessed against it and
has not executed any waiver of any

                                       32
<PAGE>

statute of limitations on the assessment or collection of any tax or
governmental charge.

None of WI's federal income tax returns and none of its state income or
franchise tax or sales or use tax returns has ever been audited by governmental
authorities. Since the date of the Financial Statements, WI has made adequate
provisions on its books of account for all taxes, assessments and governmental
charges with respect to its business, properties and operations for such period.
WI has withheld or collected from each payment made to each of its employees,
the amount of all taxes (including, but not limited to, federal income taxes,
Federal Insurance Contribution Act taxes and Federal Unemployment Tax Act taxes)
required to be withheld or collected therefrom, and has timely paid the same to
the proper tax receiving officers or authorized depositaries.

          (z) Insurance. WI has in full force and effect fire and casualty
insurance policies, with extended coverage, sufficient in amount (subject to
reasonable deductibles) to allow it to replace any of its properties that might
be damaged or destroyed. WI does not have any term life insurance, payable to
WI, on the lives of any of its officers, directors or employees. WI has in full
force and effect products liability and errors and omissions insurance in
amounts customary for companies similarly situated.

          (aa) Minute Books. The minute books of WI provided to TRW contain a
complete summary of all meetings directors and stockholders since the time of
incorporation and reflect all transactions referred to in such minutes
accurately in all material respects.

          (bb) Labor Agreements and Actions. WI is not bound by or subject to
(and none of its assets or properties is bound by or subject to) any written or
oral, express or implied, contract, commitment or arrangement with any labor
union, and no labor union has requested or, to the best of WI's knowledge, has
sought to represent any of the employees, representatives or agents of WI. There
is no strike or other labor dispute involving WI pending, or to the best of WI's
knowledge, threatened, that could have a material adverse effect on the assets,
properties, financial condition, operating results, or business of WI (as such
business is presently conducted and as it is proposed to be conducted), nor is
WI aware of any labor organization activity involving its employees. WI is not
aware that any officer or key employee, or that any group of key employees,
intends to terminate their employment with WI, nor does WI have a present
intention to terminate the employment of any of the foregoing. The employment of
each officer and employee of WI is terminable at the will of WI. To the best of
its knowledge, WI has complied in all material respects with all applicable
state and federal equal employment opportunity and other laws related to
employment.

          (cc) Section 83(b) Elections. To the best of WI's knowledge, all
individuals who have purchased shares of WI's Common Stock have timely filed
elections under Section 83(b) of the Code and any analogous provisions of
applicable state tax laws.


                                       33
<PAGE>

          (dd) Real Property Holding Company. WI is not a real property holding
company within the meaning of Section 897 of the Code and Section 1.897-2(b) of
the Treasury Regulations promulgated by the Internal Revenue Service.

          (ee) Solvency. Prior to, upon and immediately after consummation of
the transactions contemplated hereby, WI is solvent, has tangible and intangible
assets having a fair value in excess of the amount required to pay its probable
liabilities on its existing debts as they become absolute and matured, and has
access to adequate capital for the conduct of its business and the ability to
pay its debts from time to time incurred in connection therewith as such debts
mature.

          (ff) Defaults. No Default or Event of Default exists on the date
hereof. WI is not in default under any provisions of its Articles or under any
material provisions of any franchise, contract, agreement, lease or other
instrument to which it is a party or by which it or its property is bound or in
material violation of any law, judgment, decree or governmental order, rule or
regulation.

          (gg) Year 2000. To WI's knowledge, all hardware and software products
used by WI in the administration and the business operations of WI will be able
to accurately process date data (including, but not limited to calculating,
comparing and sequencing) from, into and between the twentieth century (through
year 1999), the year 2000 and the twenty-first century, including leap year
calculations, when used in accordance with the product documentation
accompanying such hardware and software products. Undefined capitalized terms
used in this Section 10.2 (WI's Warranties) will have the meaning ascribed to
them in the Series F Preferred Stock Purchase Agreement.

10.3 NO COMMITMENT TO DEVELOP LICENSED PRODUCTS

     WI represents that as of the Effective Date, it is WI's intention to
continue development of the Spitfire Products, and to manufacture and market

that the equipment will be free from defects in material and workmanship under
normal use and service. Manufacturer's sole obligation under this Warranty is
limited to replacing or repairing, at its option, at its factory, any equipment
which is returned to Manufacturer, transportation, duties, and taxes prepaid, *.
In the case of Equipment not of Manufacturers own manufacture, the warranty
under the terms of this Paragraph is available only for a period of one (1) year
after delivery. Manufacturer shall return the equipment to Distributor freight
prepaid. THIS WARRANTY IS EXPRESSED IN LIEU OF ALL OTHER WARRANTIES, EXPRESS,
IMPLIED OR STATUTORY, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE, AND OF ALL OTHER OBLIGATIONS OR LIABILITIES ON
THE PART OF MANUFACTURER AND IT NEITHER ASSUMES NOR AUTHORIZES ANY OTHER PERSON
TO ASSUME FOR MANUFACTURER ANY OTHER LIABILITIES IN CONNECTION WITH THE SALE OF
EQUIPMENT. IN NO EVENT WILL MANUFACTURER BE LIABLE FOR CONSEQUENTIAL DAMAGES
EVEN IF MANUFACTURER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. This
Warranty does not apply to any of such Equipment which shall have been repaired
or altered, except by Manufacturer, or which shall have been subjected to
misuse, negligence, or accident or operation outside the environmental

applicable, whichever is longer.

11.0    PATENT INFRINGEMENT. Manufacturer will defend any action, including a
claim or suit, against Distributor claiming that Products infringe any patent,
and will pay all costs and damages finally awarded in any such action, provided
that Manufacturer is notified promptly in writing of the action and at
Manufacturer's request and at its expense is given control of such action and
all requested information and assistance to settle or defend the same. Should
use of Products be enjoined as a result of such action, then Manufacturer shall
in a reasonable time either: (a) obtain for Distributor the right to continue to
use the Products; (b) modify or replace the Products with noninfringing
Products; or (c) request the return of the Products and upon their return refund
the value of the Products as amortized over a presumed five (5) year
depreciation period, as well as transportation costs. Manufacturer shall have no
obligation to defend any claims arising out of combinations of the Products when
used in combination with other products not supplied by Manufacturer. THE
FOREGOING STATES THE SOLE AND EXCLUSIVE LIABILITY OF MANUFACTURER FOR PATENT
INFRINGEMENT AND IS IN LIEU OF ANY OTHER WARRANTY AGAINST INFRINGEMENT OF ANY
KIND, EXPRESS, IMPLIED, OR STATUTORY.

12.0    DAMAGE LIMITATION. INDEPENDENTLY OF ANY OTHER LIMITATION HEREOF AND
REGARDLESS OF WHETHER THE PURPOSE OF ANY REMEDY SET FORTH HEREIN IS SERVED, IT
IS AGREED THAT IN NO EVENT SHALL MANUFACTURER BE LIABLE FOR SPECIAL, INCIDENTAL
OR CONSEQUENTIAL DAMAGES OF ANY KIND UNDER THIS AGREEMENT.

part thereof for any purpose not inconsistent with the terms of this Agreement;

                  (b) Debtor shall be entitled to receive and retain

Purchase Note or this Agreement shall be effective unless it is in a writing

     Premises nor promises to alter, remodel or improve the Premises have been
     made by Landlord, unless such are expressly set forth in this Lease. Tenant
     shall, upon demand, execute and deliver to Landlord a letter of acceptance
     of delivery of the Premises.

     continue in full force and effect for the number of months specified as the
     Length of Term in the Basic Lease Information or until this Lease is

     prescribe.

     B. Tenant shall not permit any odors, smoke, dust, gas, substances, noise
     or vibrations to emanate from the Premises, nor take any action which would

     upon or permitted to remain outside the Premises except in trash containers
     placed inside exterior enclosures designated for that purpose by Landlord.

     C. Tenant shall not use the Premises or permit anything to be done in or

     ordinance or governmental rule or regulation now in force or which may
     hereafter be enacted or promulgated. Tenant shall at its sole cost and
     expense obtain any and all licenses or permits necessary for Tenant's use
     of the Premises. Tenant shall promptly comply with the requirements of any
     board of fire underwriters or other similar body now or hereafter
     constituted relating to or affecting the condition, use or occupancy of the
     Premises. The judgement of any court of competent jurisdiction or the
     admission of Tenant in any actions against Tenant, whether Landlord be a
     party thereto or not, that Tenant has so violated any such law, statute,
     ordinance, rule, regulation or requirement, shall be conclusive of such
     violation as between Landlord and Tenant. Tenant shall not do or permit
     anything to be done in, on, or about the Premises or bring or keep anything
     which will in any way increase the rate of any insurance upon the Premises,
     Building or Project, or upon any contents therein or cause a cancellation
     of said insurance or otherwise affect said insurance in any manner. Tenant
     shall indemnify Landlord and hold Landlord harmless against any loss,
     expense, damage, attorneys' fees or liability arising out of the failure of
     Tenant to comply with any applicable law or comply with the requirements as
     set forth herein.

RULES AND REGULATIONS

5.   Tenant and Tenant's agents, employees, and invitees shall faithfully
     observe and comply with any rules and regulations Landlord may from time to
     time prescribe in writing for the purpose of maintaining the proper care,
     cleanliness, safety, traffic flow and general order of the Premises or
     Project. Landlord shall not be responsible to Tenant for the non-compliance
     by any other tenant or occupant of the Building or Project with any of the
     rules and regulations.

RENT
See Addendum 2

6.   Tenant shall pay to Landlord, without demand throughout the Term, Rent as
     specified in the Basic Lease Information, payable in monthly installments
     in advance on or before the first day of each calendar month, in lawful
     money of the United States, without deduction or offset whatsoever to
     Landlord at the address specified in the Basic Lease information or to such
     other firm or to such other place as Landlord may from time to time
     designate in writing. Rent for the first full month of the Term shall be
     paid by Tenant upon Tenant's execution of this Lease. If the obligation for
     payment of Rent commences on other than the first day of a month, then Rent
     shall be prorated and the prorated installment shall be paid on the first
     day of the calendar month next succeeding the Term Commencement Date.

BASIC OPERATING COST

7.   A. BASIC OPERATING COST. In addition to the Base Rent required to be paid
     hereunder, Tenant shall pay as additional Rent, Tenant's Proportionate
     Share, as defined in the Basic Lease Information, of Basic Operating Cost
     in the manner set forth below. Basic Operating Cost shall mean all expenses
     and costs of every kind and nature which Landlord shall pay or become
     obligated to pay, or would be required to pay if the Project were fully
     occupied, because of or in connection with the management, maintenance,
     preservation and operation of the Project and its supporting facilities
     servicing the Project (determined in accordance with generally accepted
     accounting principles, consistently applied) including but not limited to
     the following:

     (1) All real estate taxes, possessory interest taxes, business or license
     taxes or fees, service payment in lieu of such taxes or fees, annual or
     periodic license or use fees, excises, transit charges, housing fund
     assessments, open space charge, assessments, levies, fees or charges,
     general and special, ordinary and extraordinary, unforeseen as well as
     foreseen, of any kind (including fees "in-lieu" of any such tax or
     assessment) which are assessed, levied, charged, confirmed, or imposed by
     any public authority upon the Project, its operations or the rent (or any
     portion or component thereof), except (a) inheritance or estate taxes
     imposed upon or assessed against the Project, or any part thereof or
     interest therein, and (b) taxes computed upon the basis of the net income
     of Landlord or the owner of any interest therein.

     (2) All insurance premiums and costs, including but not limited to, any
     deductible amounts, premiums and cost of fire, casualty and liability
     coverage, rental abatement and special hazard insurance applicable to the
     Project and Landlord's personal property used in connection therewith;
     provided, however, that Landlord may, but shall not be obligated to, carry
     special hazard insurance covering losses caused by casualty not insured
     under standard fire and extended coverage insurance.

     (3) Repairs, replacements and general maintenance for the Premises,
     Building and Project (except for those repairs expressly the responsibility
     of Landlord, those repairs paid for by proceeds of insurance or by Tenant
     or other third parties, and alterations attributable solely to tenants of
     the Project other than Tenant).

     (4) All maintenance, janitorial and service agreements and used in
     maintaining the Premises, Building and Project and the equipment therein
     and the adjacent sidewalks, driveways, parking and service areas,
     including, without limitation, alarm service, window cleaning, elevator
     maintenance, Building exterior maintenance and landscaping.

(5)  Utilities which benefit all or a portion of the Premises.

(6)  A management and accounting cost recovery equal to three percent (3%) of
     Base Rent.

     In the event that the building is not fully occupied during any fiscal year
     of the Term as determined by Landlord, an adjustment shall be made in
     computing the Basic Operating Cost for such year so that Basic Operating
     Cost shall be computed as though the building had been one hundred percent
     (100%) occupied; provided, however, that in no event shall Landlord be
     entitled to collect in excess of one hundred percent (100%) of the total
     Basic Operating Cost from all of the tenants in the Building including
     Tenant.

     All costs and expenses shall be determined in accordance with generally
     accepted accounting principles which shall be consistently applied. Basic
     Operating Cost shall not include specific costs incurred for the account
     of, separately billed to and paid by specific tenants. Notwithstanding
     anything herein to the contrary, any instance wherein Landlord, at
     Landlord's sole discretion, deems Tenant to be responsible for any amounts
     greater than its Proportionate Share, Landlord shall have the right to
     allocate costs in any manner Landlord deems appropriate.

     B. PAYMENT OF ESTIMATED BASIC OPERATING COST. "Estimated Basic Operating
     Cost" for any particular year shall mean Landlord's estimate of the Basic
     Operating Cost for such fiscal year made prior to commencement of such
     fiscal year as hereinafter provided. Landlord shall have the right from
     time to time to revise its fiscal year and interim accounting periods so
     long as the periods as so revised are reconciled with prior periods in
     accordance with generally accepted accounting principles applied in a
     consistent manner. During the last month of each fiscal year during the
     Term, or as soon thereafter as practicable, Landlord shall give Tenant
     written notice of the Estimated Basic Operating Cost for the ensuing fiscal
     year. Tenant shall pay Tenant's Proportionate Share of the Estimated Basic
     Operating Costs with installments of Base Rent for the fiscal year to which
     the Estimated Basic Operating Cost applies in monthly installments on the
     first day of each calendar month during such year, in advance. If at any
     time during the course of the fiscal year, Landlord determines that Basic
     Operating Cost will apparently vary from the then Estimated Basic Operating
     Cost by more than ten percent (10%), Landlord may, by written notice to
     Tenant, revise the Estimated Basic Operating Cost for the balance of such
     fiscal year and Tenant shall pay Tenant's Proportionate Share of the
     Estimated Basic Operating Cost as so revised for the balance of the then
     current year on the first of each calendar month thereafter.

     C. COMPUTATION OF BASIC OPERATING COST ADJUSTMENT. "Basic Operating Cost
     Adjustment" shall mean the difference between Estimated Basic Operating
     Cost and Basic Operating Cost for any fiscal year determined as hereinafter
     provided. Within one hundred twenty (120) days after the end of each fiscal
     year, as determined by Landlord, or as soon thereafter as practicable,
     Landlord shall deliver to Tenant a statement of Basic Operating Cost for
     the fiscal year just ended accompanied by a computation of Basic Operating
     Cost Adjustment. If such statement shows that Tenant's payment based upon
     Estimated Basic Operating Cost is less than Tenant's Proportionate Share of
     Basic Operating Cost, then Tenant shall pay to Landlord the difference
     within twenty (20) days after receipt of such statement. If such statement
     shows that Tenant's payments of Estimated Basic Operating Cost exceed
     Tenant's Proportionate Share of Basic Operating costs, then (provided that
     Tenant is not in default under this Lease), Landlord shall pay to Tenant
     the difference within twenty (20) days of such statement. If this Lease has
     been terminated or the Term hereof has expired prior to the date of such
     statement, then the Basic Operating Cost Adjustment shall be paid by the
     appropriate party within twenty (20) days after the date of delivery of the
     statement. Should this Lease commence or terminate at any time other than
     the first day of the fiscal year, Tenant's Proportionate Share of the Basic
     Operating Cost adjustment shall be prorated by reference to the exact
     number of calendar days during such fiscal year for which Tenant is
     obligated to pay Base Rent.

     D. NET LEASE. This shall be a net Lease and Base Rent shall be paid to
     Landlord absolutely net of all costs and expenses except as herein
     provided. The provisions for payment of Basic Operating Cost and the Basic
     Operating Cost Adjustment are intended to pass on to Tenant and reimburse
     Landlord for all costs and expenses of the nature described in paragraph 7A
     incurred in connection with ownership and operation of the Building or
     Project and such additional facilities now and in subsequent years as may
     be determined by Landlord to be necessary to the Building or Project.

     E. TENANT AUDIT. Tenant shall have the right, at Tenant's expense and upon
     not less than five (5) days prior written notice to Landlord, to review at
     reasonable times, in Landlord's office, Landlord's books and records
     applicable to Tenant's Lease for purposes of verifying Landlord's
     calculation of the Basic Operating Cost and Basic Operating Cost
     Adjustment.

     In the event that Tenant shall dispute the amount set forth in any
     statement provided by Landlord under paragraph 7B or 7C above, Tenant shall
     have the right, not later than twenty (20) days following the receipt of
     such statement and upon condition that Tenant shall first deposit with
     Landlord the full amount in dispute, to cause Landlord's books and records
     with respect to such fiscal year to be audited by certified public
     accountants selected by Tenant and subject to Landlord's reasonable right
     of approval. The Basic Operating Cost Adjustment shall be appropriately
     adjusted on the basis of such audit. If such audit discloses a liability
     for a refund in excess of ten percent (10%) of Tenant's Proportionate Share
     of the Basic Operating Cost Adjustment previously reported, the cost of
     such audit shall be borne by Landlord; otherwise the cost of such audit
     shall be paid by Tenant. If Tenant shall not request an audit in accordance
     with the provisions of this paragraph 7E within twenty (20) days of receipt
     of Landlord's statement provided pursuant to paragraph 7B or 7C, such
     statement shall be final and binding for all purposes hereof.

     against fire, lightning, extended coverage, vandalism and malicious
     mischief in an amount not less than eighty percent (80%) of the
     replacement cost thereof. Such insurance shall be for the sole benefit
     of Landlord and under its sole control. Landlord shall not be
     obligated to insure any furniture, equipment, machinery, goods or
     supplies not covered by this Lease which Tenant may keep or maintain
     in the Premises or any leasehold improvements, additions or
     alterations which Tenant may make upon the Premises.

     B. LIABILITY INSURANCE. Tenant shall purchase at its own expense and keep
     in force during this Lease a policy or policies of comprehensive liability
     insurance, including personal injury and property damage, in the amount of
     not less than Five Hundred Thousand Dollars ($500,000.00) for property
     damage and Two Million Dollars ($2,000,000.00) per occurrence for personal
     injuries or deaths of persons occurring in or about the Premises and
     Project. Said policies shall (1) name Landlord and, if applicable, its
     agent, and any party holding an interest to which this Lease may be
     subordinated as additional insureds, (2) be issued by an insurance company
     acceptable to Landlord and licensed to do business in the State of
     California, and (3) provide that said insurance shall not be cancelled
     unless thirty (30) days prior written notice shall have been given to
     Landlord. Said policy or policies or certificates thereof shall be
     delivered to Landlord by Tenant upon commencement of the lease and upon
     each renewal of said insurance.

     C. INDEMNIFICATION. Landlord shall not be liable to Tenant for any loss or
     damage to person or property caused by theft, fire, act of God, acts of a
     public enemy, riot, strike, insurrection, war, court order, requisition or
     order of governmental body or authority or for any damage or inconvenience
     which may arise through repair or alteration of any part of the Building or
     Project or failure to make any such repair except as expressly otherwise
     provided in Paragraphs 10 and 12. Tenant shall indemnify Landlord and hold
     Landlord harmless from any and all loss, cost, damage, injury or expense
     arising out of or related to (1) claims of injury to or death of persons or
     damage to property occurring or resulting directly or indirectly from the
     use or occupancy of the Premises, or from activities of Tenant, its agents,
     servants, employees or anyone in or about the Premises or Project, or from
     any cause whatsoever, (2) claims for work or labor performed, or for
     materials or supplies furnished to or at the request of Tenant or in
     connection with performance of any work done for the account of Tenant
     within the Premises or Project, and (3) claims arising from any breach or
     default on the part of Tenant in the performance of any covenant contained
     in this Lease. Such indemnity shall include without limitation the
     obligation to provide all costs of defense against any such claims
     including any action or proceeding brought against Landlord. The foregoing
     indemnity shall not be applicable to claims arising from the active
     negligence or willful misconduct of Landlord. The provisions of this
     paragraph shall survive the expiration or termination of this Lease with
     respect to any claims or liability occurring prior to such expiration or
     termination.

WAIVER OF SUBROGATION

9.   To the extent permitted by law and without affecting the coverage provided
     by insurance required to be maintained hereunder, Landlord and Tenant each
     waive any right to recover against the other (a) damages for injury to or
     death of persons, (b) damages to property, (c) damages to the premises or
     any part thereof, or (d) claims arising by reason of the foregoing. This
     provision is intended to waive fully, and for the benefit of each party,
     any rights and/or claims which might give rise to a right of subrogation on
     any insurance carrier. The coverage obtained by each party pursuant to this
     Lease shall include, without limitation, a waiver of subrogation by the
     carrier which conforms to the revisions of this paragraph.

LANDLORD'S REPAIRS AND SERVICES

10.  Landlord shall at Landlord's expense maintain the structural soundness of
     the roof, foundations and exterior walls of the Building in good repair,
     reasonable wear and tear excepted. The term walls as used herein shall not
     include windows, glass or plate glass, doors, special store fronts or
     office entries. The term roof as used herein shall not include skylights,
     smoke hatches or roof vents. Landlord shall perform on behalf of Tenant and
     other tenants of the Project the maintenance of the public and common areas
     of the Project including but not limited to the landscaped areas, parking
     areas, driveways, the truck staging areas, rail spur areas, fire sprinkler
     systems, sanitary and storm sewer lines, utility services, electric and
     telephone equipment servicing the Building(s), exterior lighting, and
     anything which affects the operation and exterior appearance of the
     Project, which determination shall be at Landlord's sole discretion. Tenant
     shall reimburse Landlord for all such costs in accordance with Paragraph 7.
     Any damage caused by or repairs necessitated by any act of Tenant may be
     repaired by Landlord at Landlord's option and at Tenant's expense. Tenant
     shall immediately give Landlord written notice of any defect or need of
     repairs after which Landlord shall have reasonable opportunity to repair
     same. Landlord's liability with respect to any defects, repairs, or
     maintenance for which Landlord is responsible under any of the provisions
     of this Lease shall be limited to the cost of such repairs or maintenance.

TENANT'S REPAIRS

11.  Tenant shall at Tenant's expense maintain all parts of the Premises in a
     good clean and secure condition promptly making all necessary repairs and
     replacements including but not limited to all windows, glass, doors and any
     special office entries, walls and wall finishes, floor covering, heating,
     ventilating and air conditioning systems, truck doors, dock bumpers, dock
     plates and levelers, roofing, plumbing work and fixtures, downspouts,
     skylights, smoke hatches and roof vents. Tenant shall at Tenant's expense
     also perform necessary pest extermination and regular removal of trash and
     debris. If required by the railroad company, Tenant agrees to sign a joint
     maintenance agreement governing the use of the rail spur, if any. Tenant
     shall, at its own expense, enter into a regularly scheduled preventive
     maintenance/service contract with a maintenance contractor for servicing
     all hot water, heating and air conditioning systems and equipment within or
     serving the Premises. The maintenance contractor and the contract must be
     approved by Landlord. The service contract must include all services
     suggested by the equipment manufacturer within the operation/maintenance
     manual and must become effective and a copy thereof delivered to Landlord
     within thirty (30) days of the Term Commencement Date. Tenant shall not
     damage any demising wall or disturb the integrity and support provided by
     any demising wall and shall, at its sole expense, immediately repair any
     damage to any demising wall caused by Tenant or its employees, agents or
     invitees.

ALTERATIONS

12.  Tenant shall not make, or allow to be made, any alterations or physical
     additions in, about or to the premises without obtaining the prior written
     consent of Landlord which consent shall not be unreasonably withheld with
     respect to proposed alterations and additions which (a) comply with all
     applicable laws, ordinances, rules and regulations, (b) are in Landlord's
     opinion compatible with the Project and its mechanical, plumbing,
     electrical, and heating/ventilation/air conditioning systems, and (c) in
     Landlord's opinion will not interfere with the use and occupancy of any
     other portion of the Building or Project by any other tenant or its
     invitees. Specifically, but without limiting the generality of the
     foregoing, Landlord shall have the right of consent for all plans and
     specifications for the proposed alterations or additions, construction
     means and methods, any contractor or subcontractor to be employed on the
     work of alteration or additions, and the time for performance of such work.
     Tenant shall also supply to Landlord any documents and information
     reasonably requested by Landlord in connection with its consideration of a
     request for approval hereunder. Tenant must have Landlord's written
     approval and all appropriate permits and licenses prior to the commencement
     of said alterations and additions. All alterations and additions permitted
     hereunder shall be made and performed by Tenant without cost or expense to
     Landlord including any costs or expenses which Landlord may incur in
     electing to have an outside agency review said plans and specifications.
     Landlord shall have the right to require Tenant to remove any or all
     alterations, additions, improvements and partitions made by Tenant and
     restore the Premises to their original condition by the termination of this
     Lease, by lapse of time or otherwise, all at Tenant's expense. All such
     removals and restoration shall be accomplished in a good workmanlike manner
     so as not to cause any damage to the Premises or Project whatsoever. If
     Landlord so elects, such alterations, physical additions or improvements
     shall become the property of Landlord and surrendered to Landlord upon the
     termination of this Lease by lapse of time or otherwise; provided, however
     that this clause shall not apply to trade fixtures or furniture owned by
     Tenant. In addition to and wholly apart from its obligation to pay Tenant's
     Proportionate Share of Basic Operating Costs, Tenant shall be responsible
     for and shall


                                      -5-
<PAGE>

     pay prior to delinquency any taxes or governmental service fees, possessory
     interest taxes, fees or charges in lieu of any such taxes, capital levies,
     or other charges imposed upon, levied with respect to or assessed against
     its personal property, on the value of its alterations, additions or
     improvements and on its interest pursuant to this Lease. To the extent that
     any such taxes are not separately assessed or billed to Tenant, Tenant
     shall pay the amount thereof as invoiced to Tenant by Landlord.

SIGNS

13.  All signs, notices and graphics of every kind or character, visible in or
     from public view or corridors, the common areas or the exterior of the
     Premises, shall be subject to Landlord's prior written approval, which
     Landlord shall have the right to withhold in its absolute and sole
     discretion. Tenant shall not place or maintain any banners whatsover or any
     window decor in or on any exterior window or window fronting upon any
     common areas or service area or upon any truck doors or man doors without
     Landlord's prior written approval which Landlord shall have the right to
     grant or withhold in its absolute and sole discretion. Any installation of
     signs or graphics on or about the Premises and Project shall be subject to
     any applicable governmental laws, ordinances, regulations and to any other
     requirements imposed by Landlord. Tenant shall remove all such signs and
     graphics by the termination of this Lease. Such installations and removals
     shall be made in such manner as to avoid injury to or defacement of the
     Premises, Building or Project and any other improvements contained therein,
     and Tenant shall repair any injury or defacement including without
     limitation discoloration caused by such installation or removal.

INSPECTION/POSTING NOTICES

14.  After reasonable notice, except in emergencies where no such notice shall
     be required, Landlord, its agents and representatives, shall have the right
     to enter the Premises to inspect the same, to clean, to perform such work
     as may be permitted or required hereunder, to make repairs or alterations
     to the Premises or Project or to other tenant spaces therein, to deal with
     emergencies, to post such notices as may be permitted or required by law to
     prevent the perfection of liens against Landlord's interest in the Project
     or to exhibit the Premises to prospective tenants, purchasers, encumbrances
     or others, or for any other purpose as Landlord may deem necessary or
     desirable; provided, however, that Landlord shall not unreasonably
     interfere with Tenant's business operations. Tenant shall not be entitled
     to any abatement of Rent by reason of the exercise of any such right of
     entry. Six months prior to the end of the lease, Landlord shall have the
     right to erect on the Premises and/or Project a suitable sign indicating
     that the Premises are available for lease. Tenant shall give written notice
     to Landlord at least thirty (30) days prior to vacating the Premises and
     shall meet with Landlord for a joint inspection of the Premises at the time
     of vacating. In the event of Tenant's failure to give such notice or
     participate in such joint inspection, Landlord's inspection at or after
     Tenant's vacating the Premises shall conclusively be deemed correct for
     purposes of determining Tenants responsibility for repairs and restoration.

UTILITIES

15.  Tenant shall pay for all water, gas, heat, air conditioning, light, power,
     telephone, sewer, sprinkler charges and other utilities and services used
     on or from the Premises, together with any taxes, penalties, surcharges or
     the like pertaining thereto, and maintenance charges for utilities and
     shall furnish all electric light bulbs ballasts and tubes. If any such
     services are not separately metered to Tenant, Tenant shall pay a
     reasonable proportion, as determined by Landlord, of all charges jointly
     serving other premises. Landlord shall not be liable for any damages
     directly or indirectly resulting from nor shall the Rent or any monies owed
     Landlord under this Lease herein reserved be abated by reason of (a) the
     installation, use or interruption of use of any equipment used in
     connection with the furnishing of any of the foregoing utilities and
     services, (b) failure to furnish or delay in furnishing any such utilities
     or services when such failure or delay is caused by acts of God or the
     elements, labor disturbances of any character, any other accidents or other
     conditions beyond the reasonable control of Landlord, or (c) the
     limitation, curtailment, rationing or restriction on use of water,
     electricity, gas or any other form of energy or any other service or
     utility whatsoever serving the Premises or Project. Landlord shall be
     entitled to cooperate voluntarily and in a reasonable manner with the
     efforts of national, state or local governmental agencies or utility
     suppliers in reducing energy or other resource consumption. The obligation
     to make services available hereunder shall be subject to the limitations of
     any such voluntary, reasonable program.

SUBORDINATION

16.  Without the necessity of any additional document being executed by Tenant
     for the purpose of effecting a subordination, this Lease shall be subject
     and subordinate at all times to (a) all ground leases or underlying leases
     which may now exist or hereafter be executed affecting the Premises and/or
     the land upon which the Premises and Project are situated, or both, and (b)
     any mortgage or deed of trust which may now exist or be placed upon said
     Project, land, ground leases or underlying leases, or Landlord's interest
     or estate in any of said items, which is specified as security.
     Notwithstanding the foregoing, Landlord shall have the right to subordinate
     or cause to be subordinated any such ground leases or underlying leases or
     any such liens to this Lease. In the event that any ground lease or
     underlying lease terminates for any reason or any mortgage or deed of trust
     is foreclosed or a conveyance in lieu of foreclosure is made for any
     reason, Tenant shall, notwithstanding any subordination, attorn to and
     become the Tenant of the successor in interest to Landlord at the option of
     such successor in interest. Tenant shall execute and deliver, upon demand
     by Landlord and in the form requested by Landlord, any additional documents
     evidencing the priority of subordination of this Lease with respect to any
     such ground leases or underlying leases or any such mortgage or deed of
     trust.

FINANCIAL STATEMENTS SEE
ADDENDUM 3

17.  At the request of Landlord, Tenant shall provide to Landlord its current
     financial statement or other information discussing financial worth which
     Landlord shall use solely for purposes of this Lease and in connection with
     the ownership, management and disposition of the property subject hereto.

ESTOPPEL
CERTIFICATE

18.  Tenant agrees from time to time within ten (10) days after request of
     Landlord, to deliver to Landlord, or Landlord's designee, an estoppel
     certificate stating that this lease is in full force and effect, the date
     to which Rent has been paid, the unexpired portion of this lease and such
     other matters pertaining to this Lease as may be reasonably requested by
     Landlord. Failure by Tenant to execute and deliver such certificate shall
     constitute an acceptance of the Premises and acknowledgement by Tenant that
     the statements included are true and correct without exception. Landlord
     and Tenant intend that any statement delivered pursuant to this paragraph
     may be relied upon by any mortgagee, beneficiary, purchaser or prospective
     purchaser of the Project or any interest therein. The parties agree that
     Tenant's obligation to furnish such estoppel certificates in a timely
     fashion is a material inducement for Landlord's execution of the Lease.

19.  Tenant agrees to deposit with Landlord upon execution of this Lease, a
     Security Deposit as stated in the Basic Lease Information which sum shall
     be held by Landlord, without obligation for interest, as security for the
     performance of Tenant's covenants and obligations under this Lease, it
     being expressly understood and agreed that such deposit is not an advance
     rental deposit or a measure of damages incurred by Landlord in case of
     Tenant's default. Upon the occurrence of any event of default by Tenant,
     Landlord may, from time to time, without prejudice to any other remedy
     provided herein or provided by law, use such fund to the extent necessary
     to make good any arrears of Rent or other payments due to Landlord
     hereunder, and any other damage, injury, expense or liability caused by
     such event of default, and Tenant shall pay to Landlord, on demand, the
     amount so applied in order to restore the Security Deposit to its original
     amount.

TENANT'S REMEDIES

20.  Tenant shall look solely to Landlord's interest in the Project for recovery
     of any judgement from Landlord. Landlord, or if Landlord is a partnership,
     its partners whether general or limited, or if it is a corporation, its
     directors, officers or shareholders, shall never be personally liable for
     any such judgement. Any lien obtained to enforce any such judgement and any
     levy of execution thereon shall be subject and subordinate to any lien,
     mortgage or deed of trust on the Project.

ASSIGNMENT AND SUBLETTING

21.  A. Tenant shall not assign or sublet the Premises or any part thereof
     without Landlord's prior written approval except as provided herein. If
     Tenant desires to assign this Lease or sublet any or all of the Premises,
     Tenant shall give Landlord written notice ninety (90) days prior to the
     anticipated effective date of the assignment or sublease. Landlord shall
     then have a period of thirty (30) days following receipt of such notice to
     notify Tenant in writing that Landlord elects either (1) to terminate this
     Lease as to the space so affected as of the date so requested by Tenant, or
     (2) to permit Tenant to assign this Lease or sublet such space, subject,
     however, to Landlord's prior written approval of the proposed assignee or
     subtenant and of any related documents or agreements associated with the
     assignment or sublease, such consent not to be unreasonably withheld so
     long as the use of the Premises by such proposed assignee or subtenant
     would be a Permitted Use and would not in Landlord's opinion increase
     Occupant Density of the Project, the proposed assignee or subtenant is of
     sound financial condition, and the proposed assignment or sublease would
     not be likely to result in any decrease in Rent. If Landlord should fail to
     notify Tenant in writing of such election within said period, Landlord
     shall be deemed to have waived option (1) above, but written approval by
     Landlord of the proposed assignee or subtenant shall be required. Failure
     by Landlord to approve a proposed assignee or subtenant shall not cause a
     termination of this Lease.

     B. Any Rent or other consideration realized by Tenant under any such
     sublease or assignment in excess of the Rent payable hereunder, after
     amortization of (1) the reasonable cost of any improvements which Tenant
     has made for the purpose of assigning or subletting all or part of the
     Premises and (2) reasonable subletting and assignment costs, shall be
     divided and paid, ten percent (10%) to Tenant, ninety percent (90%) to
     Landlord.

     C. In any subletting or assignment undertaken by Tenant, Tenant shall
     diligently seek to obtain the maximum rental amount available in the
     marketplace for such subletting or assignment.

     D. If Tenant is a corporation, a transfer of corporate shares by sale,
     assignment, bequest, inheritance, operation of law or other disposition
     (including such a transfer to or by a receiver or trustee in federal or
     state bankruptcy, insolvency or other proceedings), so as to result in a
     change in the present control of such corporation or any of its parent
     corporations by the person or persons owning a majority of said corporate
     shares, shall constitute an assignment for purposes of this paragraph.

     E. If Tenant is a partnership, joint venture or other unincorporated
     business form, a transfer of the interest of persons, firms or entities
     responsible for managerial control of Tenant by sale, assignment, bequest,
     inheritance, operation of law or other disposition, so as to result in a
     change in the present control of said entity and/or a change in the
     identity of the persons responsible for the general credit obligations of
     said entity shall constitute an assignment for all purposes of this
     paragraph.

     F. No assignment or subletting by Tenant shall relieve Tenant of any
     obligation under this Lease. Any assignment or subletting which conflicts
     with the provisions hereof shall be void.

QUIET ENJOYMENT

22.  Landlord represents that it has full right and authority to enter into this
     Lease and that Tenant, upon paying the Rent and performing its other
     covenants and agreements herein set forth, shall peaceably and quietly
     have, hold and enjoy the Premises for the Term hereof without hindrance or
     molestation from Landlord, subject to the terms and provisions of this
     Lease.

CONDEMNATION

23.  A. If the whole or any substantial portion of the Project of which the
     Premises are a part should be taken or condemned for any public use under
     governmental law ordinance or regulation, or by right of eminent domain, or
     by private purchase in lieu thereof, and the taking would prevent or
     materially interfere with the Permitted Use of the Premises, this lease
     shall terminate and the Rent shall be abated during the unexpired portion
     of this Lease, effective when the physical taking of said Premises shall
     have occured.

     B. If a portion of the Project of which the Premises are a part should be
     taken or condemned for any public use under any governmental law,
     ordinance, or regulation, or by right of eminent domain, or by private
     purchase in lieu thereof, and this Lease is not terminated as provided in
     the subparagraph 23A above, this Lease shall not terminate, but the Rent
     payable hereunder during the unexpired portion of the Lease shall be
     reduced to such extent as may be fair and reasonable under all of the
     circumstances.

     C. Landlord shall be entitled to any and all payment, income, rent, award,
     or any interest therein whatsoever which may be paid or made in connection
     with such taking or conveyance and Tenant shall have no claim against
     Landlord or otherwise for the value of any unexpired portion of this Lease.
     Notwithstanding the foregoing paragraph, any compensation specifically
     awarded Tenant for loss of business, Tenant's personal property, moving
     cost or loss of goodwill, shall be and remain the property of Tenant.

CASUALTY DAMAGE

24.  A. If the Premises should be damaged or destroyed by fire, tornado or other
     casualty, Tenant shall give immediate written notice thereof to Landlord.
     Within thirty (30) days of such notice, Landlord shall notify Tenant
     whether in Landlord's opinion such repairs can be made either (1) within
     ninety (90) days, (2) in more than ninety (90) days but in less than one
     hundred eighty (180) days, or (3) in more than one hundred eighty (180)
     days from the date of such notice; Landlord's determination shall be
     binding on Tenant.

     B. If the Premises should be damaged by fire, tornado or other casualty but
     only to such extent that rebuilding or repairs can in Landlord's estimation
     be completed within ninety (90) days after the date upon which Landlord is
     notified by Tenant of such damage, this Lease shall not terminate, and
     Landlord shall at its sole cost and expense thereupon proceed with
     reasonable diligence to rebuild and repair the Premises to substantially
     the condition in which they existed prior to such damage, except that
     Landlord shall not be required to rebuild, repair or replace any part of
     the partitions, fixtures, additions and other improvements which may have
     been placed in, on or about the Premises by Tenant. If the Premises are
     untenantable in whole or in part following such damage, the Rent payable
     hereunder during the period in which they are untenantable shall be reduced
     to such extent as may be fair and reasonable under all of the
     circumstances.


     C. If the Premises should be damaged by fire, tornado or other casualty but
     only to such extent that rebuilding or repairs can in Landlord's estimation
     be completed in more than ninety (90) days but in less than one hundred
     eighty (180) days, then Landlord shall have the option of either (1)
     terminating the Lease effective upon the date of the occurrence of such
     damage, in which event the Rent shall be abated during the unexpired
     portion of the Lease, or (2) electing to rebuild or repair the Premises to
     substantially the condition in which they existed prior to such damage
     except that Landlord shall not be required to rebuild, repair or replace
     any part of the partitions, fixtures, additions and other improvements
     which may have been placed in, on or about the Premises by Tenant. If the
     Premises are untenantable in whole or in part following such damage, the
     Rent payable hereunder during the period in which they are untenantable
     shall be reduced to such extent as may be fair and reasonable under all of
     the circumstances. In the event that Landlord should fall to complete such
     repairs and rebuilding within one hundred eighty (180) days after the date
     upon which Landlord is notified by Tenant of such damage, such period of
     time to be extended for delays caused by the fault or neglect of Tenant or
     because of acts of God, acts of public agencies, labor disputes, strikes,
     fires, freight embargoes, rainy or stormy weather, inability to obtain
     materials, supplies or fuels, or delay of the contractors or subcontractors
     due to such causes or other contingencies beyond the reasonable control of
     Landlord, Tenant may at its option terminate this Lease by delivering
     thirty (30) days prior written notice of termination to Landlord as
     Tenant's exclusive remedy, whereupon all rights and obligations hereunder
     shall cease and terminate.

     D. If the Premises should be so damaged by fire, tornado, or other casualty
     that rebuilding or repairs cannot in Landlord's estimation be completed
     within one hundred eighty (180) days after the date upon which Landlord is
     notified by Tenant of such damage, this Lease shall terminate and the Rent
     shall be abated during the unexpired portion of this Lease, effective upon
     the date of the occurrence of such damage.

     E. Notwithstanding anything herein to the contrary, in the event that
     holder of any indebtedness secured by a mortgage or deed of trust covering
     the Premises requires that the insurance proceeds be applied to such
     indebtedness, then Landlord shall have the right to terminate this Lease by
     delivering written notice of termination to Tenant within fifteen (15) days
     after such requirement is made by any such holder, whereupon all rights and
     obligations hereunder shall cease and terminate.


                                      -7-
<PAGE>

     F. The provisions of Section 1942, Subdivision 2, and Section 1933,
     Subdivision 4, of the Civil Code of California is superseded by the
     foregoing.


HOLDING OVER

25.  If Tenant shall retain possession of the Premises or any portion thereof
     without Landlord's consent following the expiration of the Lease or sooner
     termination for any reason, then Tenant shall pay to Landlord for each day
     of such retention triple the amount of the daily rental for the last month
     prior to the date of expiration or termination. Tenant shall also indemnify
     and hold Landlord harmless from any loss or liability resulting from delay
     by Tenant in surrendering the Premises, including, without limitation, any
     claims made by any succeeding tenant founded on such delay. Alternatively,
     if Landlord gives notice of Landlord's consent to Tenant's holding over,
     such holding over shall constitute renewal of the Lease on whatever terms
     are specified in such notice. Acceptance of Rent by Landlord following
     expiration or termination shall not constitute a renewal of this Lease, and
     nothing contained in this paragraph shall waive Landlord's right of reentry
     or any other right. Unless Landlord exercises the option hereby given to
     it, Tenant shall be only a Tenant at sufferance, whether or not Landlord
     accepts any Rent from Tenant while Tenant is holding over without
     Landlord's written consent. Additionally, in the event that upon
     termination of the Lease, Tenant has not fulfilled its obligation with
     respect to repairs and cleanup of the Premises or any other Tenant
     obligations as set forth in this Lease, then Landlord shall have the right
     to perform any such obligations as it deems necessary at Tenant's sole cost
     and expense, and any time required by Landlord to complete such obligations
     shall be considered a period of holding over and the terms of this
     paragraph shall apply.

DEFAULT

26.  A. EVENTS OF DEFAULT: The occurrence of any of the following shall
     constitute an event of default on the part of Tenant:

     (1) ABANDONMENT. Vacation or abandonment of the Premises for a continuous
     period in excess of five (5) days. Tenant waives any right to notice Tenant
     may have under Section 1951.3 of the Civil Code of the State of California,
     the terms of this subparagraph 26A being deemed such notice to Tenant as
     required by said Section 1951.3.

     (2) NONPAYMENT OF RENT. Failure to pay any installment of Rent or any other
     amount due and payable hereunder upon the date when said payment is due,
     such failure continuing without cure by payment of the delinquent Rent and
     late charge or other obligations for a period of five (5) days after
     written notice and demand; provided, however, that except as expressly
     otherwise provided herein, Landlord shall not be required to provide such
     notice more than twice during the Term, the third such non-payment
     constituting default for all purposes hereof without requirements of
     notice.

     (3) OTHER OBLIGATIONS. Failure to perform any obligations, agreement or
     covenant under this Lease other than those matters specified in
     subparagraphs (1) and (2) of this subparagraph 26A, such failure continuing
     for fifteen (15) days after written notice of such failure, or such longer
     period as Landlord determines to be necessary to remedy such default,
     provided that Tenant shall continuously and diligently pursue such remedy
     at all times until such default is cured.

     (4) GENERAL ASSIGNMENT. A general assignment by Tenant for the Benefit of
     creditors.

     (5) BANKRUPTCY. The filing of any voluntary petition in bankruptcy by
     Tenant, or the filing of an involuntary petition by Tenant's creditors,
     which involuntary petition remains undischarged for a period of thirty (30)
     days. In the event that under applicable law the trustee in bankruptcy or
     Tenant has the right to affirm this Lease and continue to perform the
     obligation of Tenant hereunder, such trustee or Tenant shall, in such time
     period as may be permitted by the bankruptcy court having jurisdiction,
     cure all defaults of Tenant hereunder outstanding as of the date of the
     affirmance of this Lease and provide to Landlord such adequate assurances
     as may be necessary to ensure Landlord of the continued performance of
     Tenant's obligations under this Lease.

     (6) RECEIVERSHIP. The employment of a receiver to take possession of
     substantially all of Tenant's assets or the premises, if such attachment or
     other seizure remains undismissed or undischarged for a period of ten (10)
     days after the levy thereof.

     (7) ATTACHMENT. The attachment, execution or other judicial seizure of all
     or substantially all of Tenant's assets of the Premises, if such attachment
     or other seizure remains undismissed or undischarged for a period of ten
     (10) days after the levy thereof.

     B. REMEDIES UPON DEFAULT.

     (1) RENT. All failures to pay any monetary obligation to be paid by Tenant
     under this Lease shall be construed as obligations for payment of Rent.

     (2) TERMINATION. In the event of the occurrence of any event of default,
     Landlord shall have the right, with or without notice or demand, to
     immediately terminate this Lease, and at any time thereafter recover
     possession of the Premises or any part thereof and expel and remove
     therefrom Tenant and any other person occupying the same, by any lawful
     means, and again repossess and enjoy the Premises without prejudice to any
     of the remedies that Landlord may have under this Lease, or at law or
     equity by reason of Tenant's default or of such termination.

     (3) CONTINUATION AFTER DEFAULT. Even though Tenant has breached this Lease
     and/or abandoned the Premises, this Lease shall continue in effect for so
     long as Landlord does not terminate Tenant's right to possession under
     paragraph 26B (2) hereof, and Landlord may enforce all its rights and
     remedies under this Lease, including but without limitation, the right to
     recover Rent as it becomes due, and Landlord, without terminating this
     Lease, may exercise all of the rights and remedies of a Landlord under
     Section 1951.4 of the Civil Code of the State of California or any
     successor code section. Acts of maintenance preservation or efforts to
     lease the Premises or the appointment of a receiver upon application of
     Landlord to protect Landlord's interest under this Lease shall not
     constitute an election to terminate Tenant's right to possession.

     C. DAMAGES UPON TERMINATION. Should Landlord terminate this Lease pursuant
     to the provisions of paragraph 26B (2) hereof, Landlord shall have all the
     rights and remedies of a Landlord provided by Section 1951.2 of the Civil
     Code of the State of California, or successor code sections. Upon such
     termination, in addition to any other rights and remedies to which Landlord
     may be entitled under applicable law, Landlord shall be entitled to recover
     from Tenant: (1) the worth at the time of award of the unpaid Rent and
     other amounts which had been earned at the time of termination, (2) the
     worth at the time of award of the amount by which the unpaid Rent which
     would have been earned after termination until the time of award exceeds
     the amount of such Rent loss that the Tenant proves could have been
     reasonably avoided, (3) the worth at the time of award of the amount by
     which the unpaid Rent for the balance of the Term after the time of award
     exceeds the amount of such Rent loss that the Tenant proves could be
     reasonably avoided, and (4) any other amount necessary to compensate
     Landlord for all the detriment proximately caused by Tenant's failure to
     perform its obligations under this Lease or which, in the ordinary course
     of things, would be likely to result therefrom. The "worth at the time of
     award" of the amounts referred to in (1) and (2), above shall be computed
     with interest at the maximum rate allowed by law. The "worth at the time of
     award" of the amount referred to in (3) above shall be computed by
     discounting such amount at the Federal Discount Rate of the Federal Reserve
     Bank of San Francisco at the time of the award plus one percent (1%).

     D. LATE CHARGE. In addition to its other remedies, Landlord shall have the
     right without notice or demand to add to the amount of any payment required
     to be made by Tenant hereunder, and which is not paid on or before the date
     the same is due, an amount equal to five percent (5%) of the delinquency
     for each month or portion thereof that the delinquency remains outstanding
     to compensate Landlord for the loss of the use of the amount not paid and
     the administrative costs caused by the delinquency, the parties agreeing
     that Landlord's damage by virtue of such delinquencies would be difficult
     to compute and the amount stated herein represents a reasonable estimate
     thereof.


                                      -8-
<PAGE>

     E. REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of
     the parties are cumulative and not alternative to the extent permitted by
     law and except as otherwise provided herein.


LIENS

27.  Tenant shall keep the Premises free from liens arising out of or related to
     work performed, materials or supplies furnished or obligations incurred by
     Tenant or in connection with work made, suffered or done by Tenant in or on
     the Premises or Project. In the event that Tenant shall not, within ten
     (10) days following the imposition of any such lien, cause the same to be
     released of record by payment or posting of a proper bond, Landlord shall
     have, in addition to all other remedies provided herein and by law, the
     right, but not the obligation, to cause the same to be released by such
     means as it shall deem proper, including payment of the claim giving rise
     to such lien. All sums paid by Landlord on behalf of Tenant and all
     expenses incurred by Landlord in connection therefore shall be payable to
     Landlord by Tenant on demand with interest at the maximum rate allowable by
     law. Landlord shall have the right at all times to post and keep posted on
     the Premises any notices permitted or required by law, or which Landlord
     shall deem proper, for the protection of Landlord, the Premises, the
     Project and any other party having an interest therein, from mechanics' and
     materialmen's liens, and Tenant shall give Landlord not less than ten (10)
     business days prior written notice of the commencement of any work in the
     Premises or Project which could lawfully give rise to a claim for
     mechanics' or materialmen's lien.

SUBSTITUTION

28.  At any time after execution of this Lease, Landlord may substitute for the
     Premises other premises in the Project (the "New Premises") upon not less
     than sixty (60) days prior written notice, in which event the New Premises
     shall be deemed to be the Premises for all purposes hereunder, provided
     however, that:

     (A) The area of the Premises is less than twenty-five (25%) of the area of
     the Project;

     (B) The New Premises shall be similar in area and in appropriateness for
     Tenant's purposes;

     (C) Any such substitution is effected for the purpose of accommodating a
     Tenant who will occupy all or a substantial portion of the Project area;
     and

     (D) If Tenant is occupying the Premises at the time of such substitution,
     Landlord shall pay the expense of physically moving Tenant, its property
     and equipment to the new premises and shall, at its sole cost, improve the
     new Premises with improvements substantially similar to those Landlord has
     committed to provide or has provided in the Premises.

TRANSFERS BY LANDLORD

29.  In the event of a sale or conveyance by Landlord of the Building, the same
     shall operate to release Landlord from any future liability upon any of the
     covenants or conditions, express or implied, herein contained in favor of
     Tenant, and in such event Tenant agrees to look solely to the
     responsibility of the successor in interests of Landlord in and to this
     Lease. This Lease shall not be affected by any such sale and Tenant agrees
     to attorn to the purchaser or assignee.

RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS

30.  All covenants and agreements to be performed by Tenant under any of the
     terms of this Lease shall be performed by Tenant at Tenant's sole cost and
     expense and without any abatement of Rent. If Tenant shall fail to pay any
     sum of money, other than Rent, required to be paid by it hereunder or shall
     fail to perform any other act on its part to be performed hereunder, and
     such failure shall continue for five (5) days after notice thereof by
     Landlord, Landlord may, but shall not be obligated to do so, and without
     waiving or releasing Tenant from any obligations of the Tenant, make any
     such payment or perform any such act on the Tenant's part to be made or
     performed. All sums so paid by Landlord and all necessary incidental costs
     together with interest thereon at the maximum rate permitted by law from
     the date of such payment by the Landlord shall be payable to Landlord on
     demand, and Tenant covenants to pay such sums, and Landlord shall have, in
     addition to any other right or remedy of Landlord, the same right and
     remedies in the event of the non-payment thereof by Tenant as in the case
     of default by Tenant in the payment of the Rent.

WAIVER

31.  If either Landlord or Tenant waives the performance of any term, covenant
     or condition contained in this Lease, such waiver shall not be deemed to be
     a waiver of any subsequent breach of the same or any other term, covenant
     or condition contained herein. The acceptance of Rent by Landlord shall not
     constitute a waiver of any preceding breach by Tenant of any term, covenant
     or condition of this Lease, regardless of Landlord's knowledge of such
     preceding breach at the time Landlord accepted such Rent. Failure by
     Landlord to enforce any of the terms, covenants or conditions of this Lease
     for any length of time shall not be deemed to waive or to decrease the
     right of Landlord to insist thereafter upon strict performance by Tenant.
     Waiver by Landlord of any term, covenant or condition contained in this
     Lease may only be made by a written document signed by Landlord.

NOTICES

32.  Each provision of this Lease or of any applicable governmental laws,
     ordinances, regulations and other requirements with reference to the
     sending, mailing or delivery of any notice or the making of any payment by
     Landlord or Tenant to the other shall be deemed to be complied with when
     and if the following steps are taken:

     A. All Rent and other payments required to be made by Tenant to Landlord
     hereunder shall be payable to Landlord at the address set forth in the
     Basic Lease Information, or at such other address as Landlord may specify
     from time to time by written notice delivered in accordance herewith.
     Tenant's obligation to pay Rent and any other amounts to Landlord under the
     terms of this Lease shall not be deemed satisfied until such Rent and other
     amounts have been actually received by Landlord.

     B. All notices, demands, consents and approvals which may or are required
     to be given by either party to the other hereunder shall be in writing and
     shall be deemed to have been fully given when deposited in the United
     States mail, certified or registered, postage prepaid, and addressed to the
     party to be notified at the address for such party specified in the Basic
     Lease Information or to such other place as the party to be notified may
     from time to time designate by at least fifteen (15) days notice to the
     notifying party. Tenant appoints as its agent to receive the service of all
     default notices and notice of commencement of unlawful detainer proceedings
     the person in charge of or apparently in charge of or occupying the
     Premises at the time, and, if there is no such person, then such service
     may be made by attaching the same on the main entrance of the Premises.

ATTORNEYS' FEES

33.  In the event either party places the enforcement of this Lease, or any part
     thereof, or the collection of any Rent due, or to become due hereunder, or
     recovery of the possession of the Premises in the hands of an attorney or
     files suit upon the same, the prevailing party shall recover its reasonable
     attorneys' fees and court costs.

SUCCESSORS AND ASSIGNS

34.  This Lease shall be binding upon and inure to the benefit of Landlord, its
     successors and assigns, and shall be binding upon and inure to the benefit
     of Tenant, its successors, and to the extent assignment may be approved by
     Landlord hereunder, Tenant's assigns.

FORCE MAJEURE

35.  Whenever a period of time is herein prescribed for action to be taken by
     Landlord, Landlord shall not be liable or responsible for, and there shall
     be excluded from the computation for any such period of time, any delays
     due to strikes, riots, acts of God, shortages of labor or materials, war,
     governmental laws, regulations or restrictions or any other causes of any
     kind whatsoever which are beyond the control of Landlord.

MISCELLANEOUS

36.  A. The term "Tenant" or any pronoun used in place thereof shall indicate
     and include the masculine or feminine, the singular or plural number,
     individuals, firms or corporations, and their and each of their respective

ADDENDA TO LEASE AGREEMENT DATED MAY 12, 1997, BETWEEN SPIEKER PROPERTIES, L.P.,
A CALIFORNIA LIMITED PARTNERSHIP, AS LANDLORD, AND WIRELESS, INC., A CALIFORNIA

                             necessary (up or down) will be made at the end of
                             each operating year.

Months 13 - 24:              Base  Rent of  $18,560.00 shall be adjusted as set
                             forth in Paragraph 6.A. In addition to Base Rent,
                             Tenant shall also pay Tenant's Proportionate
                             Share of Basic Operating Costs as set forth in
                             Paragraph 7.

                             shall be adjusted as set forth in Paragraph 6.A. In
                             addition to Base Rent, Tenant shall also pay
                             Tenant's Proportionate Share of Basic Operating

                             addition to Base Rent, Tenant shall also pay
                             Tenant's Proportionate Share of Basic Operating
                             Costs as set forth in Paragraph 7.

Months 49 - 60:              Base Rent as calculated for the months 37 - 48
                             shall be adjusted as set forth in Paragraph 6.A. In
                             addition to Base Rent, Tenant shall also pay
                             Tenant's Proportionate Share of Basic Operating
                             Costs as set forth in Paragraph 7.

6.A. ADJUSTMENT OF BASE RENT

(1)  ANNIVERSARY DATE. If the Term Commencement Date is the first day of the
     calendar month, then the Anniversary Date shall be that day and month of
     the calendar year. If the Term Commencement Date is any day other than the
     first day of the calendar month, then the Anniversary Date shall be the
     first day of the calendar month next succeeding the Term Commencement Date.

(2)  ADJUSTMENT. Commencing with the Anniversary Date of the thirteenth (13th)
     month of the Lease Term, and each and every Anniversary Date thereafter,
     the Base Rent shall be adjusted by any increase in the Consumer Price Index
     (CPI) as determined by the U.S. Bureau of Labor Statistics. All Urban
     Consumers, for the Metropolitan Area of San Francisco, Oakland, San Jose,
     base reference period: 1982-1984 = 100, over the previous twelve (12)
     months. Such adjustment will not represent an increase in Base Rent of less
     than four percent (4%) or greater than eight percent (8%) in any twelve
     (12) month adjustment period. It is recognized by both parties that the CPI
     for any month is not published for approximately two (2) months. Tenant
     shall, therefore, continue to pay monthly Base Rent at the same amount as
     the previous month until such time as the new adjusted Base Rent is
     calculated and, at that time, Tenant shall pay the new Base Rent plus any
     arrearages.
