    THIS SUMMARY HIGHLIGHTS INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS.
SINCE 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 CAREFULLY AND
CONSIDER THE INFORMATION UNDER "RISK FACTORS" AND IN OUR FINANCIAL STATEMENTS
AND THE NOTES RELATING TO THESE FINANCIAL STATEMENTS, TOGETHER WITH THE
INFORMATION INCLUDED ELSEWHERE IN THIS PROSPECTUS, BEFORE DECIDING WHETHER TO
INVEST IN OUR COMMON SHARES. OUR FISCAL YEAR ENDS ON THE FRIDAY NEAREST
JUNE 30. EXCEPT WHERE OTHERWISE NOTED, THE INFORMATION IN THIS PROSPECTUS IS
BASED UPON INFORMATION AS OF JANUARY 18, 2000.


                                  OUR COMPANY

    We provide compact wireless communications systems using GSM, an
international standard for voice and data communications. We have pioneered what
we believe is the only commercially available system that provides all of the
infrastructure equipment and software necessary to support an entire wireless
network within a single, compact enclosure. We have designed our systems to
serve the following applications in a cost-effective manner:

    - WIRELESS OFFICES. Our systems allow wireless users in organizations such
      as large corporations, government entities and universities to maintain
      contact with the organization's private telephone network whether the
      users are in their offices, out of their offices or moving between
      locations.

    - COMMUNITY NETWORKS. Our systems enable wireless service providers to add
      capacity in heavy usage areas and to provide telephone service in
      previously unserved communities.

    Our core product, WAVEXpress, delivers a comprehensive set of wireless
network capabilities which are based on the GSM standard. WAVEXpress systems can
serve as:

    - a base station to receive and transmit voice and data signals over radio
      frequencies;

    - a switch to route voice and data signals to their correct destinations;

    - a base station controller to manage voice and data signals between the
      base station and the switch; or

    - any combination of these functions depending on our system's hardware and
      software configuration.

    Our all-in-one solution, the Network In A Box, provides the capabilities of
a complete wireless network in an enclosure approximately the size of a personal
computer tower.


    We market and sell our systems around the world utilizing a three-pronged
sales strategy which includes selling to communications equipment providers, to
systems integrators which integrate our systems with the products of other
companies and through our own direct sales force. Since 1997 we have sold over
1,000 units which have been installed in 17 countries worldwide. We have
established a strategic alliance with Nortel Networks, which accounted for 51%
of our revenues in 1999 and which, assuming the exercise of all warrants, owns
approximately 22.4% of our outstanding shares.


    Despite our successes, we face many challenges and risks. For example, we
did not record any revenue from our first product sale until 1997 and we have
not achieved, and we may never achieve, profitability. In fact, we expect to
incur net losses in the future and these losses may be substantial. Accordingly,
you should carefully consider the information set forth in the "Risk Factors"
section of this prospectus.

                                  OUR STRATEGY

    Our goal is to be the premier global provider of cost-effective, compact
wireless systems in targeted segments of the GSM market. As key elements of our
strategy, we intend to:

    - Provide wireless office systems that will replace traditional office
      telephone equipment with wireless equipment


    - Deliver wireless systems using the Internet Protocol, which is the
      networking standard used to deliver voice and data over the Internet


    - Further penetrate existing market opportunities

    - Strengthen and expand relationships with communications equipment
      providers

    - Use technological leadership to provide competitive advantages for
      wireless service providers

                             CORPORATE INFORMATION

    We were incorporated in Bermuda on June 17, 1994. Our principal executive

                                  RISK FACTORS

    INVESTING IN OUR COMMON SHARES INVOLVES A HIGH DEGREE OF RISK. IF ANY OF THE
FOLLOWING RISKS OCCUR, THE MARKET PRICE OF OUR COMMON SHARES COULD DECLINE AND
YOU COULD LOSE ALL OR PART OF YOUR INVESTMENT.

BECAUSE WE HAVE A LIMITED OPERATING HISTORY, WE CANNOT BE SURE THAT WE CAN
SUCCESSFULLY EXECUTE OUR BUSINESS STRATEGY

    We did not record revenue from our first product sale until May 1997. We
have a limited history of generating significant revenues. Many of our products
have only recently been introduced and many of our customers are testing our
products for incorporation into live networks. Therefore, you have limited
historical financial data and operating results with which to evaluate our
business and our prospects. You must consider our prospects in light of the
early stage of our business in a new and rapidly evolving market. Our limited
operating history may make it difficult for you to assess, based on historical
information, whether we can successfully execute our business strategy. If we
are unable to successfully execute our business strategy, we would likely not
achieve anticipated levels of revenue growth. In this event, we would be unable
to achieve profitability or build a sustainable business.

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


    As of September 30, 1999, we had an accumulated deficit of $121.2 million.
We incurred net losses of approximately $29.2 million, $30.8 million,
$24.5 million and $9.5 million in the fiscal years ended June 30, 1997, 1998 and
1999 and the three months ended September 30, 1999, respectively. We expect to
continue to incur net losses and these losses may be substantial. Furthermore,
we expect to generate significant negative cash flow in the future. We will need
to generate substantially higher revenues to achieve and sustain profitability
and positive cash flow. Our ability to generate future revenues and achieve
profitability will depend on a number of factors, many of which are beyond our
control. These factors include:


    - the rate of market acceptance of compact mobile wireless systems;

    - our ability to compete successfully against much larger GSM communications
      equipment providers; and

    - our ability to continue to expand our customer base.

Due to these factors, as well as other factors described in this risk factors
section, we may be unable to achieve or maintain profitability. If we are unable
to achieve or maintain profitability, we will be unable to build a sustainable
business. In this event, our share price and the value of your investment would
likely decline.

OUR QUARTERLY OPERATING RESULTS ARE LIKELY TO FLUCTUATE SIGNIFICANTLY AND MAY
FAIL TO MEET THE EXPECTATIONS OF SECURITIES ANALYSTS AND INVESTORS, WHICH MAY
CAUSE OUR SHARE PRICE TO DECLINE

    Our quarterly operating results have fluctuated significantly in the past
and are likely to do so in the future. If our operating results do not meet the
expectations of securities analysts and investors, our share price is likely to
decline. The many factors that could cause our quarterly results to fluctuate
include:

    - any delay in our introduction of new products or product enhancements;

    - the size and timing of customer orders and our product shipments, which
      have typically consisted of a relatively small number of units of wireless
      network systems at the end of each quarter;

    - the mix of products sold because our various products generate different
      gross margins;

                                       8
<PAGE>
    - any delay in shipments caused by component shortages or other
      manufacturing problems, extended product testing or regulatory issues;

    - the timing of orders from and shipments to major customers, including
      possible cancellation of orders and failure of major customers to meet
      applicable minimum purchase commitments;

    - the loss of a major customer;

    - reductions in the selling prices of our products;

    - cost pressures from shortages of skilled technical employees, increased
      product development and engineering expenditures and other factors; and

    - customer responses to announcements of new products and product
      enhancements by competitors and the entry of new competitors into our
      market.

Due to these and other factors, our results of operations could fluctuate
substantially in the future, and quarterly comparisons may not be reliable
indicators of future performance. In addition, because many of our expenses for
personnel, facilities and equipment are relatively fixed in nature, if revenues
fail to meet our expectations, we may not be able to reduce expenses
correspondingly. As a result, we would experience greater than expected net
losses. If we experience greater than expected net losses, our share price and
the value of your investment would likely decline.

WE RELY ON A SMALL NUMBER OF CUSTOMERS FOR MOST OF OUR REVENUES, AND A DECREASE
IN REVENUES FROM THESE CUSTOMERS COULD SERIOUSLY HARM OUR BUSINESS

    A small number of customers have accounted for a significant portion of our
revenues to date. Net revenues from significant customers as a percentage of our
total net revenues in the two most recent fiscal years and the three months
ended September 30, 1999 were as follows:

</TABLE>

    Nortel Networks is one of our principal shareholders, and a Nortel Networks
employee is a member of our board of directors. ADC Telecommunications and
Hutchison Whampoa, the parent of Hutchison Telecommunications Group, through a
wholly-owned subsidiary, are shareholders of ours. Microcellular Systems, Ltd.
was created by a spin-off from ADC Telecommunications in May 1999.

    We expect that the majority of our revenues will continue to depend on sales
to a small number of customers. If any key customers experience a downturn in
their business or shift their purchases to our competitors, our revenues and
operating results would decline.

    We expect that for the foreseeable future a significant portion of our net
revenues will be derived from sales to Nortel Networks and Alcatel. If our
revenues, including those expected from Nortel Networks and Alcatel under our
purchase and distribution agreements, are lower than expected, we may not be
able to quickly reduce expenses because many of our expenses are fixed in the
near term. Nortel Networks and Alcatel have minimum purchase commitments under
their respective agreements. We rely in part on these commitments in forecasting
production quantities each quarter. We have also committed to Nortel Networks
and Alcatel that we will maintain quality, delivery, performance and design
standards for our systems. As a result, we bear the risk of carrying excess
inventory if Nortel

                                       9
<PAGE>
Networks and Alcatel fail to meet their commitments or if we fail to meet ours.
From time to time, we have failed to deliver certain product features by
specific milestone dates and, as a result, we have renegotiated downward minimum
quarterly commitments with Nortel Networks, including in the three months ending
September 30, 1999. We cannot assure you that these minimum commitments will be
met or that they will not be renegotiated downward in the future. Failure of
Nortel Networks or Alcatel to meet minimum purchase commitments could cause our
revenues and operating results to decline.

WE CURRENTLY DEPEND ON TWO CONTRACT MANUFACTURERS FOR MOST OF OUR PRODUCTS AND
PLAN TO USE ONLY A SINGLE CONTRACT MANUFACTURER IN THE FUTURE AND THIS
TRANSITION COULD CAUSE DISRUPTIONS IN OUR BUSINESS

    We depend on two contract manufacturers for most of our products. We do not
have long-term supply contracts with our contract manufacturers, and they are
not obligated to supply us with products for any specific period, in any
specific quantity or at any specific price, except as may be provided in a
particular purchase order. None of our products are manufactured by more than
one supplier, and we do not expect this to change for the foreseeable future.

    We plan to consolidate the manufacture of our products with one of our
existing contract manufacturers, PEMSTAR, Inc., by the middle of calendar year
2000. We may lose revenue and damage our customer relationships if we do not
manage this consolidation effectively.

    There are risks associated with our dependence on contract manufacturers,
including the contract manufacturer's control of capacity allocation, labor
relations, production quality and other aspects of the manufacturing process. If
we are unable to obtain our products from manufacturers on schedule, revenues
from the sale of those products may be delayed or lost, and our reputation,
relationship with customers and our business could be harmed. In addition, in
the event that a contract manufacturer must be replaced, the disruption to our
business and the expense associated with obtaining and qualifying a new contract
manufacturer could be substantial. If problems with our contract manufacturers
cause us to miss customer delivery schedules or result in unforeseen product
quality problems, we may lose customers. As a result, our revenues and our
future growth prospects would likely decline.

BECAUSE SOME OF OUR KEY COMPONENTS COME FROM A SINGLE SOURCE, OR REQUIRE LONG
LEAD TIMES, WE COULD EXPERIENCE UNEXPECTED INTERRUPTIONS WHICH COULD CAUSE OUR
OPERATING RESULTS TO SUFFER

    We believe that a number of our suppliers are sole sources for key
components. These key components are complex and difficult to manufacture and
require long lead times. In the event of a reduction or interruption of supply,
or a degradation in quality, as many as six months could be required before we
would begin receiving adequate supplies from other suppliers. Supply
interruptions could delay product shipments, causing our revenues and operating
results to decline.

WE DO NOT TYPICALLY HAVE A SALES BACKLOG AND THEREFORE MAY INCUR EXPENSES FOR
EXCESS INVENTORY OR BE UNABLE TO MEET CUSTOMER REQUIREMENTS

    We do not have a significant backlog because our customers typically give us
firm purchase orders with short lead times before requested shipment. However,
our contract manufacturers require commitments from us so that they can allocate
capacity and be assured of having adequate components and supplies from third
parties. Failure by us to accurately estimate product demand could cause us to
incur expenses related to excess inventory or prohibit us from meeting customer
requirements.

                                       10
<PAGE>
OUR PRODUCTS ARE COMPLEX AND MAY HAVE ERRORS OR DEFECTS THAT ARE DETECTED ONLY
AFTER DEPLOYMENT IN COMPLEX NETWORKS, WHICH MAY HARM OUR BUSINESS

    Our products are highly complex and are designed to be deployed in complex
networks. Although our products are tested during manufacturing and prior to
deployment, they can only be fully tested when deployed in networks with
high-call volume. Consequently, our customers may discover errors after the
products have been fully deployed. If we are unable to fix errors or other
problems that may be identified in full deployment, we could experience:

    - costs associated with the remediation of any problems;

    - loss of or delay in revenues;

    - loss of customers;

    - failure to achieve market acceptance and loss of market share;

    - diversion of deployment resources;

    - increased service and warranty costs;

    - legal actions by our customers; and

    - increased insurance costs.

    In addition, our products often are integrated with other network
components. There may be incompatibilities between these components and our
products that could significantly harm the service provider or its subscribers.
Product problems in the field could require us to incur costs to remedy the
problems and subject us to liability for damages caused by the problems. These
problems could also harm our reputation and competitive position in the
industry.

WE MAY EXPERIENCE DIFFICULTIES IN THE INTRODUCTION OF NEW OR ENHANCED PRODUCTS
THAT COULD RESULT IN SIGNIFICANT, UNEXPECTED EXPENSES OR DELAY THEIR LAUNCH,
WHICH WOULD HARM OUR BUSINESS

    The development of new or enhanced products is a complex and uncertain
process. We may experience design, manufacturing, marketing and other
difficulties that could delay or prevent our development, introduction or
marketing of new products or product enhancements. We must also effectively
manage the transition from old products to new or enhanced products. In
particular, we are currently developing a system providing voice communication
over the Internet for commercial release in fiscal year 2000. We cannot assure
you that we will be able to develop, introduce or manage this or any other new
products or product enhancements in a timely manner or at all. Failure to
develop new products or product enhancements in a timely manner would
substantially decrease market acceptance and sales of our products.

FAILURE TO COMPLY WITH REGULATIONS AFFECTING THE TELECOMMUNICATIONS INDUSTRY
COULD SERIOUSLY HARM OUR BUSINESS AND RESULTS OF OPERATIONS

    Our failure to comply with government regulations relating to the
telecommunications industry in countries where our products are deployed and
failure to comply with any changes to those regulations could seriously harm our
business and results of operations. We have not completed all activities
necessary to comply with existing regulations and requirements in some of the
countries in which we intend to sell our products. Compliance with the
regulations of numerous countries could be costly and require delays in
deployments.

                                       11
<PAGE>
OUR FAILURE TO COMPLY WITH EVOLVING INDUSTRY STANDARDS COULD DELAY OUR
INTRODUCTION OF NEW PRODUCTS


    An international consortium of standards bodies is working to establish the
specifications of a future wireless standard and its interoperability with
existing standards. Any failure of our products to comply could delay their
introduction and require costly and time consuming engineering changes. After
the future standard is adopted, any delays in our introduction of next
generation products could impair our ability to grow revenues in the future. As
a result, we may be unable to achieve or sustain profitability.


OUR MARKET OPPORTUNITY COULD BE SIGNIFICANTLY DIMINISHED IN THE EVENT THAT GSM
OR ANY SUBSEQUENT GSM-BASED STANDARDS DO NOT CONTINUE TO BE OR ARE NOT WIDELY
ADOPTED

    Our products are designed to utilize only GSM, an international standard for
voice and data communications. There are other competing standards including
code division multiple access, or CDMA, and time division mutiple access, or
TDMA. We currently do not have plans to offer products that utilize these
standards. In the event that GSM or any GSM-based standards do not continue to
be or are not broadly adopted, our market opportunity could be significantly
limited, which would seriously harm our business.

WE HAVE A LONG SALES CYCLE, WHICH COULD CONTRIBUTE TO FLUCTUATIONS IN OUR
RESULTS OF OPERATIONS AND SHARE PRICE

    Our sales cycle is typically long and unpredictable, making it difficult to
plan our business. The long sales cycle also requires us to invest resources in
a possible transaction that may not be recovered if we do not successfully
conclude the transaction. Factors that affect the length of our sales cycle
include:

    - time required for testing and evaluation of our products before they are
      deployed in a network;

    - size of the deployment;

    - complexity of the customer's network environment; and

    - the degree of system configuration necessary to deploy our products.

    In addition, the emerging and evolving nature of the market for the systems
we sell may lead prospective customers to postpone their purchasing decisions.
General concerns regarding year 2000 compliance may further delay purchase
decisions by prospective customers. Our long and unpredictable sales cycle can
result in delayed revenues, difficulty in matching revenues with expenses and
increased expenditures, which together may contribute to declines in our results
of operations and our share price.

INTENSE COMPETITION IN THE WIRELESS MARKET COULD PREVENT US FROM INCREASING OR
SUSTAINING REVENUES OR ACHIEVING OR SUSTAINING PROFITABILITY

    The wireless market is rapidly evolving and highly competitive. We cannot
assure you that we will have the financial resources, technical expertise or
marketing, manufacturing, distribution and support capabilities to compete
successfully in the future. We expect that competition in each of our markets
will increase in the future.

    In the wireless office network market, the primary competing standard for
our systems is the digital European cordless telephone standard known as DECT.
In the community network market, we compete against wireless local loop
networks, which are wireless communication systems that connect users to the
public telephone network using radio signals as a substitute for traditional
telephone connections.

                                       12
<PAGE>
    We currently compete against communications equipment providers such as
Ericsson, Lucent, Motorola, Nokia and Siemens in the GSM, CDMA, TDMA, DECT and
wireless local loop markets. In some market applications, we also compete with
our customers Alcatel and Nortel Networks. All of the major communications
equipment providers have broad product lines that include at least partial
solutions that address our target markets.

    In addition, we are seeking to sell our products in emerging markets, many
of which have less reliable traditional telephone infrastructures than developed
countries. If these countries improve the reliability and service of their
traditional telephone networks, the demand for our products in these markets
could be harmed and our future revenue growth could decline.

    Many of our competitors and potential competitors have substantially greater
name recognition and technical, financial and sales and marketing resources than
we have. Such competitors may undertake more extensive marketing campaigns,
adopt more aggressive pricing policies and devote substantially more resources
to developing new products than we can. Trends toward increased consolidation in
the telecommunications industry may increase the size and resources of some of
our current competitors and could affect some of our current relationships.

    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. Competitive pressures we face may cause our revenues or growth to
decline and may therefore seriously harm our business and results of operations.

IF WE ARE UNABLE TO MANAGE OUR GLOBAL OPERATIONS EFFECTIVELY, OUR BUSINESS WOULD
BE SERIOUSLY HARMED

    Substantially all of our revenue to date has been derived from systems
intended for installation outside of the United States. In addition to the
regulatory issues discussed previously, our operations are subject to the
following risks and uncertainties:

    - legal uncertainties regarding liability, tariffs and other trade barriers;

    - greater difficulty in accounts receivable collection and longer collection
      periods;

    - costs of staffing and managing operations in several countries;

    - difficulties in protecting intellectual property rights;

    - changes in currency exchange rates which may make our U.S.
      dollar-denominated products less competitive in global markets;

    - the impact of recessions in global economies; and

    - political and economic instability.

    We expect to establish manufacturing operations in China during calendar
year 2000 which may subject us to all of the risks listed above, particularly
the difficulty of protecting intellectual property rights.


WE HAVE EXPERIENCED AN INCREASE IN SALES TO COMPANIES IN THE PEOPLES REPUBLIC OF
CHINA, AND FUTURE SALES IN CHINA WILL BE SUBJECT TO ECONOMIC AND POLITICAL RISKS



    In the three months ended September 30, 1999, sales to HangZhou Topper
Electric, which is located in the Peoples Republic of China, accounted for 38%
of our revenues. China may represent a significant future market opportunity for
interWAVE due to its economic growth and the relative


                                       13
<PAGE>

inadequacy of its traditional telephone network. Sales in China pose significant
additional risks, which include:



    - potential inability to enforce contracts or take other legal action,
      including actions to protect intellectual property rights;



    - difficulty in collecting revenues and risks related to fluctuations in
      currency exchange rates, particularly when sales are denominated in the
      local currency rather than in U.S. dollars;



    - changes in U.S. foreign trade policy towards China which may restrict our
      ability to export products to or make sales in China, and similar changes
      in China's policy regarding the U.S.; and



    - changes in government regulation affecting companies doing business in
      China, either through export sales or local manufacturing operations.



    In the event our revenue levels from sales to China increase, we will become
increasingly subject to these risks. The occurrence of any of these risks would
harm our revenues from China and could in turn cause our revenues or growth to
decline and harm our business and results of operations.


IF WE FAIL TO IMPROVE OUR OPERATIONAL SYSTEMS AND CONTROLS TO MANAGE FUTURE
GROWTH, OUR BUSINESS COULD BE SERIOUSLY HARMED

    We plan to continue to expand our operations significantly to pursue
existing and potential market opportunities. This growth places significant
demands on our management and our operational resources. In order to manage
growth effectively, we must implement and improve our operational systems,
procedures and controls on a timely basis. In addition, we expect that we will
need to expand our principal U.S. facilities in the next six to 12 months and
may be required to move our offices to a different location. A move could be
disruptive to our operations and could delay production or development
activities.

IF WE ARE UNABLE TO HIRE OR RETAIN KEY PERSONNEL, WE MIGHT NOT BE ABLE TO
OPERATE OUR BUSINESS SUCCESSFULLY

    Our business is highly dependent on our ability to attract, retain and
motivate qualified technical and management personnel. Competition is intense
for qualified personnel in our industry and in Northern California, where most
of our engineering personnel are located, and we may not be successful in
attracting and retaining these personnel. We do not have non-compete agreements
with any of our key employees. We currently do not maintain key person life
insurance on any of our key executives. Our success also depends upon the
continuing contributions of our key management and our research, product
development, sales and marketing and manufacturing personnel. Many of these
would be difficult to replace, in particular Dr. Priscilla Lu, our Chief
Executive Officer and Chairman of the Board, Ian Sugarbroad, our President and
Chief Operating Officer and Thomas Hubbs, our Executive Vice President and Chief
Financial Officer.

OUR INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS MAY BE INSUFFICIENT TO PROTECT
OUR COMPETITIVE POSITION

    We cannot assure you that the protection offered by our U.S. patents will be
sufficient or that any of our pending U.S. or foreign patent applications will
result in the issuance of patents. In addition, competitors in the United States
and other countries, many of whom have substantially greater resources, may
apply for and obtain patents that will prevent or interfere with our ability to
make and sell our products in the U.S. and/or abroad. Unauthorized parties may
attempt to design around our patents, copy or otherwise obtain and use our
products. We cannot be certain that the steps we have taken will prevent
unauthorized use of our technology, particularly in countries where the laws may
not

                                       14
<PAGE>
protect our proprietary rights as fully as in the United States. Failure to
protect our proprietary rights could harm our competitive position and therefore
cause our revenues and operating results to decline.

    On June 28, 1999, we filed a complaint against JetCell Corporation in the
United States District Court for the Northern District of California alleging
misappropriation of trade secrets and patent infringement. JetCell has filed a
series of counterclaims against us, which include allegations of unfair trade
practices, unfair competition, defamation, patent misuse and patent invalidity.
We are unable to predict the outcome of this litigation and do not expect it to
be resolved in the near future. The legal proceedings may be distracting to our
management and expensive and the outcome could be adverse to us. If the outcome
is adverse to us, we could experience more competition or could be required to
license our technology, either of which could harm our business and financial
results. See "Legal Proceedings."

CLAIMS THAT WE INFRINGE THIRD-PARTY INTELLECTUAL PROPERTY RIGHTS COULD RESULT IN
SIGNIFICANT EXPENSES AND RESTRICTIONS ON OUR ABILITY TO SELL OUR PRODUCTS IN
PARTICULAR MARKETS

    From time to time, third parties may assert patent, copyright, trademark and
other intellectual property rights to technologies that are important to our
business. Any claims could result in costly litigation, divert the efforts of
our technical and management personnel, cause product shipment delays, require
us to enter into royalty or licensing agreements or prevent us from making or
selling certain products. Any of these could seriously harm our operating
results. Royalty or licensing agreements, if available, may not be available on
commercially reasonable terms, if at all. In addition, in some of our sales
agreements, we agree to indemnify our customers for any expenses or liabilities
resulting from claimed infringements of patents, trademarks or copyrights of
third parties. Costs associated with these indemnification obligations could be
significant and could cause our operating results and stock price to decline.

WE MAY NOT BE ABLE TO LICENSE NECESSARY THIRD-PARTY TECHNOLOGY OR IT MAY BE
EXPENSIVE TO DO SO

    From time to time, we may be required to license technology from third
parties to develop new products or product enhancements. We have licensed
software for use in our products from Lucent Technologies, TCSI Inc., Trillium
Digital Systems Inc., and Wind River Associates. We cannot assure you that
third-party licenses will be available to us on commercially reasonable terms,
if at all. The inability to obtain any third-party license required to develop
new products and product enhancements could require us to obtain substitute
technology of lower quality or performance standards or at greater cost which
could seriously harm our competitive position, revenues and growth prospects.

    There are a number of general GSM patents held by different companies which
may impact our technology. If any of our products infringe on any of these
patents and we are unable to negotiate license agreements, then we may be
required to redesign a portion of our product line.

WE MAY BE UNABLE TO MEET OUR FUTURE CAPITAL REQUIREMENTS WHICH WOULD LIMIT OUR
ABILITY TO GROW AND COMPETE EFFECTIVELY, RESULTING IN SUBSTANTIAL HARM TO OUR
BUSINESS AND RESULTS OF OPERATIONS

    We may require additional funding, which may not be available on terms which
are favorable to us. Currently, we do not have a credit facility or any lines of
credit. If we issue equity securities, existing shareholders may experience
dilution or the new equity securities may have rights, preferences and
privileges senior to those of existing shareholders. If additional funds are
raised through the issuance of debt securities, such securities would have
rights, preferences and privileges senior to holders of common shares. If we
cannot raise funds on terms favorable to us, we may not be able to develop or
enhance our products, take advantage of future opportunities or respond to
competitive pressures or unanticipated requirements. See "Use of Proceeds,"
"Dilution" and "Management's Discussion and

                                       15

Analysis of Financial Condition and Results of Operations--Liquidity and Capital
Resources" for more information on our capital requirements.

IF WE, OUR SUPPLIERS OR OUR CUSTOMERS FAIL TO BE YEAR 2000 COMPLIANT, OUR
BUSINESS COULD BE SEVERELY DISRUPTED

    The risk that software or hardware may inaccurately process dates beginning
in the year 2000 and beyond presents several potential problems for our
business. In particular, we are subject to the following:

    - 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;

    - shutdowns or slowdowns of our business as a result of a failure of our
      internal management systems, which could disrupt our business operations;

    - interruption of product or component supplies or a reduction in product
      quality as a result of the failure of systems used by our contract
      manufacturers or suppliers; and

    - reductions or deferrals in sales activities as a result of year 2000
      compliance problems of our customers.

    Our products may contain undetected errors or defects associated with year
2000 date functions. Known or unknown errors or defects in our products could
result in delay or loss of revenue, diversion of development resources, damage
to our reputation, product liability claims or increased service and warranty
costs, any of which could significantly harm our business and operating results.
Some industry analysts have predicted significant litigation regarding year 2000
compliance issues. It is uncertain whether or to what extent we may be affected
by any litigation.

    If we, our contract manufacturers, suppliers or customers fail to identify
and correct any year 2000 problems or unanticipated or unremedied year 2000
problems arise, these failures or problems could result in an interruption in or
a failure of our normal business activities and operations. If a year 2000
problem related to a contract manufacturer or supplier occurs, it may be
difficult to determine which suppliers' products have caused the problem. These
failures could interrupt our operations and damage our relationships with our
customers. Due to the general uncertainty inherent in the year 2000 problem, we
are unable to determine at this time whether any external year 2000 failures
will harm us.

    Any failure by us, our contract manufacturers or any of our suppliers to be
year 2000 compliant could seriously interrupt our manufacturing process, thereby
substantially reducing our revenues.


    We believe our year 2000 worst case scenario would be the failure of a sole
or limited source supplier to be year 2000 compliant. Our failure or the failure
of one of these suppliers to be year 2000 compliant could seriously interrupt
our manufacturing process, thereby substantially reducing our revenues. To date,
we have not experienced any material disruption in our operations as a result of
year 2000 problems, nor have we incurred any unplanned expenses to address year
2000 concerns.


CONTROL BY OUR EXISTING SHAREHOLDERS COULD DISCOURAGE THE POTENTIAL ACQUISITION
OF OUR BUSINESS


    Upon completion of this offering, our executive officers, directors and 5%
or greater shareholders and their affiliates will own 30,882,609 shares or
approximately 70.4% of our outstanding common shares assuming the exercise of
all warrants and options held by them. Acting together, these shareholders would
be able to control all matters requiring approval by shareholders, including the
election of directors. This concentration of ownership could have the effect of
delaying or preventing a change in control of our business or otherwise
discouraging a potential acquirer from attempting to obtain control of us, which
could prevent our shareholders from realizing a premium over the market price
for their common shares.


                                       16
<PAGE>
OUR BYE-LAWS MAY DISCOURAGE POTENTIAL ACQUISITIONS OF OUR BUSINESS

    Some of our bye-laws and Bermuda law may discourage, delay or prevent a
merger or acquisition that shareholders may consider favorable. This may reduce
the market price of our common shares. A summary of these provisions is included
in "Description of Share Capital--Antitakeover Effects of Some Provisions of
Memorandum of Association and Bye-laws."

OUR BYE-LAWS PROVIDE FOR WAIVER OF CLAIMS BY SHAREHOLDERS AND INDEMNIFY
DIRECTORS AND OFFICERS

    Our bye-laws provide for a broad indemnification of actions of directors and
officers. Under the bye-laws, the shareholders agree to waive claims against
directors and officers for their actions in the performance of their duties,
except for acts of fraud or dishonesty. These waivers will not apply to claims
arising under the United States federal securities laws and will not apply to
the extent that they conflict with provisions of the laws of Bermuda or with the
fiduciary duties of our directors and officers.

OUR OPERATIONS BASED IN BERMUDA MAY BE SUBJECT TO UNITED STATES TAXATION, WHICH
COULD SIGNIFICANTLY HARM OUR BUSINESS AND OPERATING RESULTS

    Except for our United States subsidiary, we do not consider ourselves to be
engaged in a trade or business in the United States. Our United States
subsidiary is subject to United States taxation on its worldwide income, and
dividends from our United States subsidiary are subject to United States
witholding tax. We and our non-U.S. subsidiaries would, however, be subject to
United States federal income tax on income related to the conduct of a trade or
business in the U.S. If we were determined to be subject to United States
taxation, our financial results would be significantly harmed. We cannot assure
you that the Internal Revenue Service will not contend that our Bermuda-based
operations are engaged in a United States trade or business and, therefore, are
subject to United States income taxation. See "Taxation" for more information on
the tax consequences of operating outside the United States.

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


    Sales of substantial amounts of our common shares in the public market
following this offering or the awareness that a large number of shares is
available for sale could cause the market price of our common shares to decline.
Upon the expiration of lock-up agreements restricting the sale of shares by our
current shareholders, 28,725,805 of our common shares will become eligible for
immediate sale. Prior to such expiration date, 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. Sales of our common shares held by existing
shareholders could cause the market price of our stock to decline.


WE MAY APPLY THE PROCEEDS OF THIS OFFERING TO USES THAT DO NOT IMPROVE OUR
OPERATING RESULTS OR MARKET VALUE

    We will have considerable discretion to use the net proceeds of this
offering for our business, and you will not have the opportunity as part of your
investment decision to assess whether the proceeds are being used appropriately.
The net proceeds may be used for corporate purposes that do not improve our
operating results or our market value. Pending application of the net proceeds,
they may be placed in investments that do not produce income or that lose value.
See "Use of Proceeds" for more information on our application of the net
proceeds.

                                       17
<PAGE>
INVESTORS IN THIS OFFERING WILL EXPERIENCE AN IMMEDIATE AND SUBSTANTIAL DILUTION
IN THE BOOK VALUE OF THEIR INVESTMENT


    The per share book value of the common shares, adjusted to reflect the net
proceeds we receive from this offering, will be substantially below the price
paid by new investors in this offering. Investors in this offering will
therefore incur immediate and substantial dilution of $6.00 per share (at an
assumed initial public offering price of $9.00). See "Dilution."


BECAUSE WE DO NOT INTEND TO PAY ANY CASH DIVIDENDS ON OUR COMMON SHARES, HOLDERS
OF OUR COMMON SHARES WILL NOT BE ABLE TO RECEIVE A RETURN ON THEIR SHARES UNLESS
THEY SELL THEM

    We have never paid or declared any cash dividends on our common shares or
other securities and intend to retain any future earnings to finance the
development and expansion of our business. We do not anticipate paying any cash
dividends on our common shares in the foreseeable future. Unless we pay
dividends, our shareholders will not be able to receive a return on their shares
unless they sell them.

THERE HAS BEEN NO PRIOR MARKET FOR OUR COMMON SHARES, AND OUR SHARE PRICE MAY
DECLINE AFTER THIS OFFERING

    The initial public offering price may not be indicative of the price that
will prevail in the open market after this offering. An active trading market
for our common shares may not develop or be sustained after this offering. The
market price of our common shares is likely to be highly volatile and could be
subject to wide fluctuations in response to various factors, some of which are
beyond our control, including:

    - changes in financial estimates of our operating results by securities
      analysts;

    - fluctuations in the valuation of companies perceived by investors to be
      comparable to us; and

    - share market price and volume fluctuations attributable to inconsistent
      trading volume levels of our shares.

    Furthermore, the 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 operating performance of those
companies. Market fluctuations as well as general economic, political and market
conditions such as recessions, interest rate changes or international currency
fluctuations, may negatively impact the market price of our common shares.

<PAGE>
                                USE OF PROCEEDS

    Based on an assumed initial public offering price of $9.00 per share, our
net proceeds from the sale of the 8.0 million common shares that we are offering
will be approximately $65.6 million after deducting the underwriting discount
and estimated expenses payable by us in connection with this offering. If the
underwriters exercise their over allotment option in full, our net proceeds will
be approximately $75.7 million.


    The principal purposes of this offering are to increase our working capital,
to fund both capital investment and research and development and other general
corporate purposes. See "Management Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources." Pending
any use of the net proceeds for the above purposes, we intend to invest the
funds in short-term, interest-bearing, investment grade securities. Other than
estimated capital expenditures of approximately $4.5 million in fiscal 2000 and
increased facility rent of approximately $1.0 million per year commencing
January 1, 2000, we have not identified specific uses for the net proceeds from
this offering. We will invest a portion of the proceeds to accelerate research
and development relating to our products based on the Internet Protocol and our
development of new products utilizing the future wireless standard. The amounts
we actually expend in these areas may vary significantly and will depend on a
number of factors, including our future revenues. Accordingly, management will
retain broad discretion in the allocation of the net proceeds of this offering.
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 proceeds.


                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our capital shares. We
currently expect to retain any future earnings for developing and expanding our
business, and therefore we do not currently expect to pay cash dividends in the
foreseeable future.

                                    DILUTION


    Our pro forma net tangible book value as of September 30, 1999 was
approximately $66.2 million or approximately $1.85 per share. Pro forma net
tangible book value per share represents pro forma tangible assets less total
liabilities, divided by our pro forma number of outstanding common shares after
giving effect to, on a pro forma basis:



    - the sale of 3,526,663 Series I1 preferred shares which closed in November
      and December 1999;



    - the issuance of 602,256 common shares upon exercise of options under our
      1994 stock plan between September 30, 1999 and January 18, 2000;



    - the exercise of a warrant for 2,000,000 preferred shares and 188,410
      common shares that the warrant holders have committed to exercise on the
      effectiveness of this offering at exercise prices ranging from $0.70 to
      $7.00 per share; and



    - the conversion of all outstanding preferred shares into 29,006,193 common
      shares immediately prior to the completion of the offering.



    Without taking into account any changes in such pro forma net tangible book
value per share after September 30, 1999, other than to give effect to the sale
of the common shares in this offering at an assumed initial public offering
price of $9.00 per share after deducting the underwriting discount and estimated
expenses payable by us and the receipt of the net proceeds of such sale, the pro
forma net tangible book value as of September 30, 1999 would have been
approximately $131.8 million or approximately $3.00 per share. This represents
an immediate increase in pro forma net tangible book value per share of $1.15 to
existing shareholders and an immediate dilution of $6.00 per share to new
investors. The following table sets forth this per share dilution:

    The foregoing discussion and table includes the exercise of a warrant for
2,000,000 preferred shares and 188,410 common shares that the warrant holder has
committed to exercise and the closing of the sale of Series I1 preferred shares
and excludes:



    - 5,317,191 common shares issuable upon the exercise of options outstanding
      at January 18, 2000 at a weighted average exercise price of $1.96 per
      share;



    - 7,286,594 common shares issuable upon exercise of warrants outstanding at
      January 18, 2000 at exercise prices ranging from $0.70 to $1.15 per share;



    - 1,818,867 common shares available for issuance under our 1999 option plan;
      and


    - 300,000 common shares available for issuance under our 1999 employee share
      purchase plan.


    If all options and warrants outstanding at January 18, 2000 were exercised,
the pro forma net tangible book value per share immediately after completion of
the offering would be $2.54, which represents an immediate dilution in net
tangible book value per share of $6.46 to purchasers of common shares in the
offering. See "Management--Employee Benefit Plans" and the notes to our
consolidated financial statements for more information on our option plans.

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

    THE FOLLOWING DISCUSSION SHOULD BE READ TOGETHER WITH OUR CONSOLIDATED
FINANCIAL STATEMENTS AND RELATED NOTES INCLUDED ELSEWHERE IN THIS PROSPECTUS.
OUR FISCAL YEAR ENDS ON THE FRIDAY NEAREST JUNE 30.

OVERVIEW


    We provide compact wireless communications systems for the GSM market. We
were incorporated in June 1994 and recorded our first product sale in May 1997.
Our systems were initially deployed to add capacity and coverage to existing
systems, primarily in Asia. Deployments of community networks began in 1998,
primarily in China and Africa. Trials of our wireless office systems commenced
in 1999 in both Europe and Asia. Prior to May 1997, we had no sales and our
operations consisted primarily of various start-up activities, such as research
and development, recruiting personnel, conducting customer field trials and
raising capital. We generated net revenues of $1.8 million in 1997,
$13.0 million in 1998, $17.3 million in 1999 and $5.4 million in the three
months ended September 30, 1999. We incurred net losses of $29.2 million in
1997, $30.8 million in 1998, $24.5 million in 1999 and $9.5 million in the three
months ended September 30, 1999. As of September 30, 1999, we had an accumulated
deficit of $121.2 million.


    We operate in a single business segment. We generate net revenues from sales
of our systems and, in connection with our direct sales activity, from
installation, maintenance contracts and support of those systems. Revenue
derived from systems sales, comprised of unit sales of our WAVEXpress base
station and base station controller, our WAVEXchange, our Network In A Box and
our WAVEView management system, constituted 96% of net revenues in 1997, 92% of
net revenues in 1998 and 88% of net revenues in 1999. Revenue is recognized when
all of the following have occurred: the system has been shipped, title and risk
of loss have passed to the customer, we have the right to invoice the customer,
collection of the receivable is probable and we have fulfilled all contractual
obligations to the customer. Revenue from installation is recognized as the
services are performed to the extent of direct installation costs incurred, and
the excess is deferred and recognized over the estimated life of the product,
while revenue from extended warranty coverage and customer support is recognized
ratably over the period of the service contract. Trial sales directly to
wireless service providers are not recognized as revenue until the trial is
completed. Trials of our systems conducted by communications equipment providers
and systems integrators are typically shipped from inventory held by those
parties and do not result in incremental revenue to us.

    Currently, our revenues are generated by sales to communications equipment
providers and system integrators that may either sell our systems on a
stand-alone basis or integrate them with their systems and by our direct sales
force. In fiscal year 1999, sales to communications equipment providers
represented 61% of total revenues, sales to systems integrators accounted for
23% of total revenues and direct sales to wireless service providers represented
16% of total revenues.

    We have entered into purchase and distribution agreements with Nortel
Networks and Alcatel. These multi-year agreements specify quarterly minimum
purchase commitments by these communications equipment providers. Nortel
Networks' quarterly purchase commitments began in June 1998 and increase
quarterly through December 2000. Alcatel's quarterly purchase commitments
commence in June 2000 and extend through December 2001. Both agreements also
obligate us to meet certain product development milestones and provide for a
reduction in Nortel Networks' and Alcatel's purchase commitments if we do not
meet our development milestones. In April 1999, we agreed to reduce Nortel
Networks' remaining quarterly commitments because we were unable to meet certain
product feature specifications provided for in the agreement. We do not rely
solely on these purchase commitments to forecast our production requirements or
anticipated sales to these customers. Rather, we also rely on our internal sales
forecasts and our ongoing discussions with these customers, including their
formal purchase orders, as guidance for planning our production and our revenue

                                       25

outlook. However, we do rely in part on these minimum purchase commitments in
forecasting production quantities. Because of the relatively fixed nature of
many of our expenses, including personnel and facilities costs, we cannot
immediately adjust expenses in response to a decline in revenues. Therefore,
failure of these customers to achieve their quarterly purchase commitments could
cause a decline in our operating results. See "Certain Transactions--Series G
Preferred Financing, Purchase and Distribution Agreement," and "Certain
Transactions--Series I1 Preferred Share Financing, Purchase and Distribution
Agreement."

    Net revenues outside the United States represented approximately 83%, 49%,
30% and 27% of total net revenues in fiscal years 1997, 1998, 1999 and for the
three months ended September 30, 1999, respectively. We have derived and expect
to continue to derive a majority of our revenues from products installed outside
the U.S. by both non-U.S. and U.S. based communications equipment providers,
systems integrators and wireless service providers, subjecting our revenue
stream to risks from economic uncertainties, currency fluctuations, political
instability and uncertain cultural and regulatory environments. All of our
revenues are in U.S. dollars, which reduces our exposure to fluctuations in
revenues attributable to changes in currency exchange rates. In addition, we
face risks inherent in conducting global business. These risks include extended
collection time for receivables, reduced ability to enforce obligations and
reduced protection for our intellectual property.


    We recorded revenue from our first product sale in May 1997. We have a
limited history of generating significant revenues, and many of our products
have only recently been introduced. We have incurred substantial operating
losses since our inception and we expect to incur net losses in the future which
may be substantial. Most of our expenses are fixed in the near term, and we may
not be able to quickly reduce spending if our revenue is lower than anticipated.
Therefore, net losses in a given quarter could be greater than expected. You
have limited historical financial data and operating results with which to
evaluate our business and our prospects. As a result, you must consider our
prospects in light of the early stage of our business in a new and rapidly
evolving market. For additional information on factors that may affect our
future results of operations, please see "Risk Factors."


    Communications equipment providers, system integrators and wireless service
providers typically perform numerous tests and extensively evaluate products
before incorporating them into their networks. The time required for testing,
evaluation and design of our systems into the service provider's network
typically ranges from six to twelve months. During the trial period we sell a
limited number of units. The successful completion of the trial phase often
results in another sale of additional units intended for deployment in
commercial service. Our business could be adversely affected if a significant
customer reduces or delays orders during our sales cycle or chooses not to
deploy networks incorporating our systems.

    Cost of revenues consists of material costs, direct labor costs, warranty
costs, royalties, overhead related to manufacturing our products, amortization
of intangible assets, and customer support costs.

    In general, our gross margins will be affected by the following factors and,
therefore, we are unable to predict what these margins will be in the future:

    - demand for our products and services;

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

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

    - the mix of products sold;

    - the sales channels through which our products are sold; and

    - the purchase volume discounts we are able to obtain from our contract
      manufacturers.

                                       26

    We currently obtain all of our primary components and subassemblies for our
products from two independent contract manufacturers. Accordingly, a significant
portion of our cost of revenues consists of payments to these suppliers. The
remainder of our cost of revenues is related to our in-house manufacturing
operations, which consist primarily of quality control, final assembly, testing
and product integration. In conjunction with the consolidation of our
manufacturing operations with a single contract manufacturer, we expect to
outsource the final assembly, testing, and product integration activity by the
middle of calendar year 2000.

    Research and development expenses consist primarily of compensation and
related costs for research and development personnel and expenses for testing
facilities and equipment. All research and development costs are expensed as
they are incurred. We expect to continue to make substantial investments in
research and development and anticipate that these expenses will continue to
increase in absolute dollars.

    Selling, general and administrative expenses consist primarily of
compensation and related costs for sales and sales support personnel, marketing
personnel, financial, accounting, human resource and general management
personnel, sales commissions, marketing programs, legal and professional
services, travel expenses, bad debt expenses and other general corporate
expenses. We expect to incur substantial expenditures related to sales and
marketing activities, the recruitment of additional sales and marketing
personnel and the expansion of our domestic and international distribution
channels. We expect selling, general and administrative expenses to increase in
absolute dollars due to the addition of sales and marketing personnel and due to
the additional costs related to the anticipated growth of our business and
operation as a public company.

    We are planning to consolidate our manufacturing activities with a single
contract manufacturer. Accordingly, our dependence on this manufacturer will
increase. Problems encountered during the consolidation or future problems
relating to the manufacturer's inability to meet our quality and delivery
specifications could harm our operating results.


    Since our inception, we have used share option programs for key employees as
compensation to attract strong business and technical talent. We have recorded
compensation expense for our option grants. The expense is equal to the excess
of the fair market price on the date of grant or sale over the option exercise
price. Of the total deferred compensation, approximately $6.4 million,
$7.6 million, $5.3 million and $3.3 million was amortized in fiscal years 1997,
1998, 1999 and the three months ended September 30, 1999, respectively. The
balance in deferred compensation of $12.1 million at September 30, 1999 is being
amortized on an accelerated basis over the vesting period of the applicable
options, which is typically four years.


    Our products operate on the GSM standard. GSM competes with other digital
standards, including code division multiple access, or CDMA, and time division
multiple access, or TDMA. GSM also competes with analog standards. In the event
that TDMA or CDMA become the dominant digital wireless communication standard in
geographic markets we are seeking to address, the acceptance of our products and
our revenues and operating results would be harmed.

    Our industry is intensely competitive, and many of our competitors are major
telecommunications equipment providers with resources that are significantly
greater than ours. In addition to competitive pressures, we will also likely
encounter declining sales prices and profit margins over time as products
mature.

    The percentage of net revenues on a fiscal year basis comprised by sales to
Nortel Networks may decline due in part to the broadening of our customer base.
Nortel Networks is a principal shareholder of ours and an employee of Nortel
Networks serves on our board of directors. ADC Telecommunications, Alcatel and
Holodeck Limited, an affiliate of Hutchison Telecommunications Group and a
wholly-owned subsidiary of Hutchison Whampoa, are shareholders of ours.
Microcellular Systems was created by a spin-off from ADC Telecommunications. Due
in part to general

improvements in economic conditions in several key Asian markets, we may
experience increased sales in Asia in future periods.



    We have also begun negotiations for a purchase/resale agreement with Intasys
Corporation, one of our shareholders. Intasys plans to market our products in
Canada. As of September 30, 1999, we had recorded $3.6 million in services
receivable from this shareholder as a result of our issuance to Intasys of a
warrant to purchase 615,000 common shares at $1.00 per share. This warrant
expires on the effectiveness of our initial public offering. See Note 9 to the
Consolidated Financial Statements.


COMPARISON OF THREE MONTHS ENDED SEPTEMBER 30, 1998 AND 1999

NET REVENUES

    Net revenues increased 20% or $0.9 million from $4.5 million for the three
months ended September 30, 1998 to $5.4 million for the three months ended
September 30, 1999. This increase was due to continued increases in the number
of active customers and the continued deployment of our systems. Four customers
accounted for all of our net revenues in the three months ended September 1998
while 11 customers accounted for all of our net revenues in the three months
ended September 1999. Sales to Nortel Networks and ADC Telecommunications
accounted for 53% and 31%, respectively, of net revenues in the three months
ended September 30, 1998, while sales to HangZhou Topper Electric Corporation
and Microcellular Systems in the United Kingdom accounted for 38% and 21%,
respectively, of net revenues in the three months ended September 30, 1999.

COST OF REVENUES

    Cost of net revenues increased 60% or $1.5 million during the three months
ended September 30, 1999 compared with the three months ended September 30,
1998. As a percentage of net revenues, cost of revenues increased from 55% for
the three months ended September 30, 1998 to 74% for the three months ended
September 30, 1999, due to the mix of products sold. In the three months ended
September 30, 1998, 38% of net revenues was attributed to our WAVEXchange and
Network In A Box products, which earn higher gross profits, while 43% was
attributed to our WAVEXpress/BTS, which earns lower gross profits. In the three
months ended September 30, 1999, 24% of net revenues was attributed to our
WAVEXchange and Network In A Box products, which earn higher gross profits,
while 65% was attributed to our WAVEXpress/BTS, which earns lower gross profits.
The product mix in any quarter will vary depending on the customer's application
and network design, and therefore our gross profits will fluctuate. Due to the
relatively short time that we have been shipping our complete product line, we
are unable to forecast with certainty our product mix on a quarterly basis.
However, we expect that our gross profits will fluctuate on a quarterly basis.

RESEARCH AND DEVELOPMENT EXPENSES

    Research and development expenses declined approximately $0.3 million or 8%
from $3.9 million for the three months ended September 30, 1998 to $3.6 million
for the three months ended September 30, 1999. The decrease was primarily due to
a $0.5 million reduction in non-recurring engineering costs and engineering
contractor expenses, partially offset by a $0.2 million increase in engineering
staff and recruiting expenses.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES


    Selling, general and administrative expenses increased $329,000 or 19%
during the three months ended September 30, 1999 compared with the three months
ended September 30, 1998. Approximately $274,000 of the increase was due to
increased sales and administration personnel and approximately $66,000 was due
to increased sales commissions on higher revenue. Selling, general and
administrative expenses are expected to continue to increase as we expand our
marketing and sales support staff to support the increased number of customers
we serve and as we increase our general, administrative and


                                       29
<PAGE>

management expenses to provide support as a public company. For example, our
chief financial officer joined our payroll in July 1999, and our president and
chief operating officer joined our payroll in September 1999.


AMORTIZATION OF DEFERRED STOCK COMPENSATION


    Amortization of deferred stock compensation increased $1,801,000 or 118%
during the three months ended September 30, 1999 compared with the three months
ended September 30, 1998. During the three months ended September 30, 1999,
options to purchase 1,973,750 common shares were granted at an average exercise
price of $1.45 resulting in an addition to deferred stock compensation of
$11.7 million.


INTEREST EXPENSE

    Interest expense increased from $49,000 in the three months ended
September 30, 1998 to $1,959,000 in the three months ended September 30, 1999.
Of the 1999 amount, $1,744,000 was due to amortization of the discount ascribed
to the warrants issued in conjunction with the bridge loan financing. See
Note 8 to the Consolidated Financial Statements. The notes were converted to
Series H1 preferred shares as of September 10, 1999. As a result of the
conversion of the notes into Series H1 preferred shares in September, the
unamortized discount was converted to additional paid-in-capital, and no further
interest expense will be incurred relative to the bridge loan financing. Should
we elect to borrow funds under our committed revolving line of credit, we will
incur interest expense during any periods when amounts are outstanding under the
line. At current interest rates, the maximum borrowings under the available line
would result in quarterly interest expense of approximately $112,000. There are
no current plans to draw down any of the available funds under this revolving
line of credit.

COMPARISON OF FISCAL YEARS ENDED JUNE 30, 1997, 1998 AND 1999

NET REVENUES

    We began generating revenue in May 1997. Net revenues increased
$11.2 million, from $1.8 million in 1997 to $13.0 million in 1998. This increase
was due primarily to the generation of revenue in four quarters of 1998 versus
only two months of 1997.

    Net revenues increased $4.3 million or 33%, from $13.0 million in 1998 to
$17.3 million in 1999. This increase was principally due to increased sales to
Nortel Networks, who began marketing our products in the fourth quarter of 1998.
Nortel Networks accounted for $8.8 million of our 1999 net revenues, an increase
of $6.4 million over 1998. This increase, however, was offset by a reduction in
sales, through ADC Telecommunications who, with our consent, assigned our
distribution agreement to Microcellular Systems, a new company formed by a group
of former ADC Telecommunications employees in the spring of 1999. ADC
Telecommunications accounted for $3.4 million of our sales in 1999 and
$6.1 million in 1998. Also, in the second half of fiscal 1998, wireless service
providers in Asia were adversely impacted by local economic conditions and
accordingly curtailed their planned programs to deploy our products aggressively
in their networks. Thus, sales to Hutchison Telecommunications Group and Total
Access Communications each declined to less than 10% of our revenues in fiscal
1999. Net revenues in 1999 included $1.0 million related to training and support
services provided to a communications equipment provider. We incurred
$0.2 million of expenses related to this net revenue.

COST OF REVENUES

    Cost of revenues increased $8.7 million from $3.6 million in 1997 to
$12.3 million in 1998. This increase is primarily attributable to the increase
in net revenues described above. As a percentage of net revenues, cost of
revenues decreased from 196% in 1997 to 94% in 1998, due primarily to a smaller
rate of increase in customer support costs than in net revenues. The 1998 cost
of revenues includes an

                                       30
<PAGE>
approximately $1.4 million charge due to an inventory write-off of product
originally ordered to satisfy anticipated product orders from our Asian
customers in the second half of fiscal 1998, but which could not be shipped due
to the economic status in that region.

    Cost of revenues increased $0.2 million from $12.3 million in 1998 to
$12.5 million in 1999. As a percentage of net revenues, cost of revenues
decreased from 94% in 1998 to 72% in 1999. The decrease in the percentage of net
revenues was primarily due to lower cost of revenues associated with the
WAVEXchange and Network In A Box products introduced in the first half of fiscal
1999.


RESEARCH AND DEVELOPMENT EXPENSES



    Research and development expenses increased $1.1 million or 8% from
$14.2 million in 1997 to $15.3 million in 1998. The major items contributing to
the increase included employee related expenses and non-recurring engineering
expenses of $1.2 million, depreciation expenses of $0.6 million, and facilities
related expenses of $0.9 million. These increases were offset by the decrease of
$1.7 million in preproduction manufacturing and service support expenses which
were classified as cost of revenues in 1998 with the deployment and shipment of
revenue.



    Research and development expenses decreased $1.1 million or 7% from
$15.3 million in 1998 to $14.2 million in 1999 primarily due to a reduction in
nonrecurring engineering costs and engineering contractors expenses of
$1.2 million. In addition, expenses were reduced $0.3 million for hiring and
relocation expense, and $0.5 million for prototype materials. These reductions
were offset with other expense increases including additional personnel costs of
$0.4 million, increased depreciation expense of $0.2 million and intangible
amortizations of $0.3 million.



    We anticipate an acceleration in research and development expenditures. From
1997 through 1999, however, the growth in our research and development
expenditures was affected by our difficulties in attracting and retaining
trained personnel. Nevertheless, we have recently begun to increase our research
and development expenses with an increase in research and development staff from
67 employees at June 30, 1999 to 75 employees at September 30, 1999. We expect
to continue to add staff to future product development activities, including
products utilizing the Internet Protocol and products utilizing the future
standard.


SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses increased $0.8 million from
$6.9 million in 1997 to $7.7 million in 1998. This increase consists of the
addition of employees in our Hong Kong and Beijing offices to support our direct
sales activity in the Pacific region and expenses associated with our
participation in the 1998 GSM World Congress in Cannes, France.

    Selling, general and administrative expenses declined $0.3 million from
$7.7 million in 1998 to $7.4 million in 1999. This decrease was due to a shift
in our sales strategy to emphasize indirect sales channels. Selling general and
administrative expenses began increasing in the fourth quarter of 1999 as we
began making investments in marketing programs and increasing our presence in
Hong Kong and Paris.

AMORTIZATION OF DEFERRED STOCK COMPENSATION

    Amortization of deferred stock compensation increased $1.2 million from
$6.4 million in 1997 to $7.6 million in 1998. Amortization of deferred stock
compensation decreased $2.3 million from $7.6 million in 1998 to $5.3 million in
1999.

INCOME TAXES

    There is no income tax on income earned in Bermuda.

    In 1997, 1998 and 1999 our U.S. subsidiary incurred net losses for United
States federal and state income tax purposes; and we recorded a provision for
income taxes of $111,000, $220,000 and $113,000, respectively, related to
current international income tax provided on the profits attributable to our
foreign operations. As of June 30, 1999, we had $23.8 million of federal and
$12.7 million of state net operating loss carryforwards to offset future taxable
income. The difference between available net operating losses and our
accumulated deficit as reported for financial statement purposes is principally
because losses incurred in Bermuda are not subject to a carry-forward since
there is no tax on income earned in Bermuda, and the losses attributable to our
U.S. subsidiary relate to the manufacturing and development operations of our
U.S. subsidiary and not to our global sales and marketing activity.

QUARTERLY RESULTS OF OPERATIONS

    The following presents net revenues for our seven most recent quarters ended
October 1, 1999.

</TABLE>

    We believe that period-to-period comparisons of our operating results are
not necessarily meaningful. You should not rely on them to predict future
performance. The amount and timing of our operating expenses may fluctuate
significantly in the future as a result of a variety of factors. We face a
number of risks and uncertainties encountered by early stage companies,
particularly those in rapidly evolving markets such as the wireless
communications industry. We may not be able to address these risks and
difficulties successfully. In addition, we may not be able to continue to add
new customers on a regular basis and our revenue may not grow, and we may not
achieve or maintain profitability in the future.

    Our quarterly and annual operating results have fluctuated in the past and
are likely to fluctuate significantly in the future. It is likely that in some
future quarter our operating results will fall below the expectations of
securities analysts and investors. In this event, the market price of our common
share could significantly decline.

    See "Risk Factors--Our quarterly operating results are likely to fluctuate
significantly and may fail to meet the expectations of securities analysts and
investors, causing our stock price to decline" for more information on the
factors affecting our quarterly results.

    Our sales cycle, which is typically between six and twelve months,
contributes to fluctuations in our quarterly operating results. Further, the
emerging and evolving nature of the market for systems such as our Network In A
Box may lead prospective customers to postpone their purchasing decisions. In
addition, general concerns regarding year 2000 compliance may further delay
purchase decisions by prospective customers.

    Most of our expenses, such as employee compensation and lease payments for
facilities and equipment, are relatively fixed in the near term. In addition,
our expense levels are based, in part, on our expectations regarding future
revenues. As a result, any shortfall in revenues relative to our expectations
could cause significant changes in our operating results from quarter to
quarter.

LIQUIDITY AND CAPITAL RESOURCES

    Since inception, we have financed our operations primarily through the sale
of preferred equity securities and more recently through the sale of secured
convertible notes and warrants.

</TABLE>


(1) A warrant to purchase an additional 1,000,000 Series A preferred shares at
    $1.00 per share was issued to EXCELlink and was exercised in May 1995.
    EXCELlink subsequently transferred the 1,000,000 Series A preferred to third
    parties.

(2) 80,000 of the 4,680,000 Series D preferred shares were sold to 15
    sophisticated individual investors. Stock options to purchase a total of
    100,000 common shares were issued to the Mayfield entities and were
    exercised in March 1997.

(3) All Series E preferred shares were sold to 75 sophisticated individual
    investors. Holodeck purchased 400,000 Series E preferred shares.

(4) Nortel Networks was the sole investor in the Series G preferred financing.
    The 3,714,286 Series G preferred shares listed includes shares issued in
    exchange for patent license rights and services to be rendered under an
    original equipment manufacturing agreement. The warrant issued to Nortel
    Networks is for 2,000,000 Series G preferred shares at $7.00 per share.
    Using the Black-Scholes option valuation model, $4,629,000 of the amount
    raised in the Series G preferred financing is attributed to the warrant.
    Additional information regarding this preferred stock financing is provided
    under "Certain Transactions-Series G Preferred Financing" and "Consolidated
    Financial Statements-Note 9".

(5) The purchase price for the 360,000 Series H preferred shares listed was paid
    by the cancellation and satisfaction of all outstanding invoices and
    indebtedness by us for services performed by ADC Telecommunications.


(6) In addition to the 1,715,715 Series H1 preferred shares listed, an
    additional 1,872,362 Series H1 preferred shares were issued upon the
    automatic conversion of our 1999 convertible note and warrant financing.
    Additional information regarding the conversion is provided under "Certain
    Transactions-Convertible Note and Warrant Financing".


Each preferred share converts automatically into 1 common share upon completion
of our initial public offering.

</TABLE>

 (1) The note and all accrued interest was paid in full in May 1998.

 (2) Financing of capital equipment under a $2.5 million secured line of credit.
     The line of credit has expired. The current outstanding balance is
     $0.7 million. The interest rate is 6% above average term treasury notes.

 (3) Notes payable, convertible by their terms upon closing of at least
     $10 million in gross proceeds in permanent preferred share financing which
     occurred on September 10, 1999, including interest accrued at 12% per annum
     from December 1998 to March 1999 and 8% per annum from March 1999 through
     September 10, 1999.


    During the second quarter of fiscal 1999, we experienced a shortage of cash.
In December 1998, we obtained a 60 day loan from Nortel Networks for
$1.4 million. On the maturity date in February 1999, we were unable to pay the
principal amount of the note. To remedy the default, we issued Nortel Networks a
warrant to acquire 24,000 common shares at an exercise price of $1.15 per share.
The principal balance of $1.4 million was applied towards a bridge loan and
warrant financing in March 1999. An additional $3.7 million was loaned to us in
this bridge loan and warrant financing in March 1999 by Nortel Networks,
EXCELlink, Mayfield Funds and Morgan Stanley Dean Witter Venture Partners. In
May and June 1999, other preferred investors loaned us $7.6 million in this
bridge loan and warrant financing. Each of our preferred shareholders were given
the opportunity to participate in this financing and, if they participated at a
minimum percentage of their initial investment, they were entitled to exchange
their original preferred shares for shares of series A1, B1, C1, D1, E1, F1 and
G1 whose terms were identical to the original preferred shares except that the
new preferred shares were preferential in liquidation to all original preferred
shares. Approximately 95% of our preferred shareholders participated at least to
their minimum level and received the senior security. In conjunction with these
loans, we issued five year warrants to purchase 6,345,939 common shares of
$0.70 per share. These warrants were valued using the Black-Scholes model at
$5,877,018. See Note 8 to the Consolidated Financial Statements.



    On September 10, 1999 we converted the principal and interest into 1,872,362
Series H1 preferred shares and issued warrants to purchase an additional
253,874 common shares at an exercise price of $1.00 per share to the
participants in the bridge loan and warrant financing. These warrants expire on
September 10, 2002 or upon the consummation of an initial public offering.


    As of September 30, 1999, cash and cash equivalents were $13.0 million. In
November and December 1999, we received $28.0 million in net proceeds from the
sale of additional preferred shares.

    We expect the net proceeds of this offering to be $65.6 million, based on an
assumed offering price of $9.00 and after deducting underwriting discounts and
estimated offering expenses. In addition, as a result of the exercise of
warrants which would otherwise expire on the effectiveness of the offering, we
could receive additional proceeds of up to $15.1 million. We plan to use
$4.5 million of the net proceeds for capital expenditures during fiscal 2000. We
also will use a portion of the net proceeds to fund increased facility rent of
$1.0 million per year beginning in fiscal 2000. We expect to use the

                                       34
<PAGE>
remainder of the net proceeds for general corporate purposes including moderate
increases from prior levels of research and development and working capital.

    Cash used in operating activities was $1.2 million for the three months
ended September 30, 1999, $13.3 million in 1999, and $21.0 million in 1998.

    Cash used in investing activities was $1.0 million for the three months
ended September 30, 1999, $2.0 million in 1999 primarily for capital equipment
purchases, and cash provided by investing activities was $0.3 million in 1998
resulting from the sale of short term investments partially offset by capital
equipment purchases.

    Cash provided by financing activities was $11.4 million for the three months
ended September 30, 1999, $11.8 million in 1999, and $13.1 million in 1998. Cash
provided by financing activities in 1999 was primarily due to issuances of
convertible notes and warrants while in 1998 cash provided by financing
activities was primarily due to issuances of preferred shares and sale of a
related warrant, partly offset by payments on notes payable to shareholders.

    Our accounts receivable balances have been dominated by large amounts due
from our principal customers who are all large, internationally recognized
corporations. While terms of sale vary from customer to customer, payment
practices of these large corporations have resulted in delays in collection and
our quarterly days sales outstanding was 134 days based on the accounts
receivable as of June 30, 1999. Based on quarterly sales and accounts receivable
as of September 30, 1999 we reduced quarterly days sales outstanding to 109
days. Depending on the mix of sales to U.S. and non-U.S. based customers, and
depending on the mix of terms of sale, our days sales outstanding will fluctuate
from period to period.

    In November 1999 we received a commitment for a $5 million revolving line of
credit from a commercial bank. This credit facility would allow us to borrow up
to 70% of eligible accounts receivable at interest rates equal to the bank
reference rate plus 1.25%. The lender would obtain a security interest in
essentially all of our assets, and advances would be subject to our compliance
with quarterly financial covenants including minimum tangible net worth, minimum
earnings before interest, taxes, depreciation and amortization, and compliance
with selected balance sheet ratios. While the lender has provided a firm
commitment, we cannot be certain that we will execute a loan agreement.

    We have no material commitments other than obligations under our facilities
leases including a lease we entered in December 1999 for our principal
engineering and administrative offices. See Note 11 and Note 15 to the
Consolidated Financial Statements for more information on our facilities leases.
Our future capital requirements will depend upon many factors, including the
timing of research and product development efforts and expansion of our
marketing efforts. We expect to continue to expend significant but smaller
amounts on property and equipment related to the expansion of our facilities,
and on research and development laboratory and test equipment, as the capital
required for volume manufacturing is being committed by our contract
manufacturers. We provide six or twelve month forecasts to our contract
manufacturers. We generally commit to purchase products to be delivered within
the next 60 days covered by these forecasts with cancellation fees. As of
December 27, 1999, we had committed to make purchases totaling $4.8 million from
these manufacturers in the next 60 days. In addition, in specific instances we
may agree to assume liability for limited quantities of specialized components
with lead times beyond this 60-day period.

    In future periods, we generally anticipate significant increases in our
working capital needs on a period-to-period basis primarily as a result of
planned increases in sales and marketing activity. In conjunction with the
expected increases in sales, we expect higher levels of inventory and trade
accounts receivable. While we also expect an increase in trade accounts payable
and other liabilities, we do not expect that they will offset the increases in
inventory and trade accounts receivable.

    We believe that continued substantial investment in research and development
is critical to attaining our strategic product and cost-reduction objectives. We
also expect to expand our field sales

                                       35
<PAGE>
and customer support organizations as customers move from trials to large scale
deployments. The growth of our business and operation as a public company will
require additional personnel and related costs, resulting in increases in our
selling, general and administrative expenses.

    We believe that the net proceeds of this offering, together with our
existing cash balances, will be sufficient to meet our capital requirements at
least through the next 12 months. However, we may need or could elect to seek
additional funding prior to that time. In November 1999, we received a
commitment from a financial institution for a revolving line of credit in the
amount of $5,000,000 for a one year term subject to advances against eligible
accounts receivable. In the event that we need to raise additional funds, we may
not be able to do so on terms favorable to us. Furthermore, if we issue equity
securities, shareholders may experience dilution or the new equity securities
may have rights, preferences and privileges senior to those of existing holders
of common shares. If additional funds are raised through the issuance of debt
securities, such securities would have rights, preferences and privileges senior
to holders of common shares, and the terms. If we cannot raise funds on terms
favorable to us, we may not be able to develop or enhance our products, take
advantage of future opportunities or respond to competitive pressures or
unanticipated requirements. See "Use of Proceeds," "Dilution" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" for more information on our capital
requirements.

YEAR 2000 COMPLIANCE

    Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. As a result, software that
records only the last two digits of the calendar year may not be able to
distinguish between 20th and 21st century dates. This may result in software
failures or the creation of erroneous results.

    We have largely completed our year 2000 readiness compliance and tested
current versions of our products and vendor's software. We believe all current
versions of our products are "year 2000 compliant," as defined below, when
configured and used in accordance with the related documentation, and provided
that the underlying operating system of the computer on which our products run
and any other software used with or in the computer on which our products run,
are compliant.

    We define "year 2000 compliant" as the ability to:

    - correctly handle date information needed for the December 31, 1999 to
      January 1, 2000 date change;

    - function according to the product documentation provided for this date
      change, without changes in operation resulting from the advent of a new
      century, assuming correct configuration;

    - if the date elements in interfaces and data storage specify the century,
      store and provide output of date information in ways that are unambiguous
      as to century; and

    - recognize the year 2000 as a leap year.

    We have tested software obtained from third parties that is incorporated
into our products, and we believe that licensed software is year 2000 compliant.
Despite testing by us and by current and potential clients, and assurances from
developers of products incorporated into our products, our products may contain
undetected errors or defects associated with year 2000 date functions. Known or
unknown errors or defects in our products could result in delay or loss of
revenue, diversion of development resources, damage to our reputation, or
increased service and warranty costs, any of which could materially adversely
affect our business, operating results or financial condition. Some industry
analysts have predicted significant litigation regarding year 2000 compliance
issues, and we are aware of such lawsuits against other vendors. Because of the
unprecedented nature of such litigation, it is uncertain whether or to what
extent we may be affected by it.

                                       36
<PAGE>
    We have initiated an assessment of our material internal information
technology systems, including both our own software products and third party
software and hardware technology. We have completed testing and we believe that
we are compliant. If our information technology systems are not year 2000
compliant, we may not have allowed sufficient time for remediation of any
deficiencies. To the extent that we are not able to test the technology provided
by third party vendors, we are seeking assurances from vendors that their
systems are year 2000 compliant. We have completed the inventory/ assessment of
licensed software included in our products and have confirmed that the licensed
software that we incorporate in our products is year 2000 compliant. This
confirmation has been achieved through a combination of internal testing,
vendor's year 2000 Readiness Disclosures, and an ongoing certification program
addressing all of our suppliers and vendors.

    We are not currently aware of any material operational issues or costs
associated with preparing our internal information technology for the year 2000.
Our costs incurred through September 30, 1999, have totaled less than $25,000.
We expect to incur less than $100,000 in costs to complete our year 2000
compliance efforts. However, we may experience material unanticipated problems
and costs caused by undetected errors or defects in the technology used in our
internal information technology systems.

    We do not currently have any information concerning the year 2000 compliance
status of some of our customers. If our current or future customers fail to
achieve year 2000 compliance or if they divert technology expenditures to
address year 2000 compliance problems, our business could suffer.

    We have funded our year 2000 plan from available cash and have not
separately accounted for these costs in the past. To date, these costs have not
been material. We expect to incur additional costs related to the year 2000 plan
for administrative personnel to manage the project, outside contractor
assistance, technical support for our products, product engineering and customer
satisfaction. In addition, we may experience material problems and costs with
year 2000 compliance that could adversely affect our business, results of
operations, and financial condition.

    We have developed and documented contingency plans for business partners
deemed to be at risk. We have also developed contingency plans for all of our
business areas. In addition, we have contingency plans for critical internal
inventory items, hardware and software, used in our internal infrastructure and
our product cycle. These plans have been documented and distributed to
potentially affected users of our systems. The overall cost of developing and
implementing our plan may be material. Finally, we are also subject to external
forces that might generally affect industry and commerce, such as utility or
transportation company year 2000 compliance failures and related service
interruptions.


    We believe our year 2000 worst case scenario would be the failure of a sole
or limited source supplier to be year 2000 compliant. Our failure or the failure
of one of these suppliers to be year 2000 compliant could seriously interrupt
our manufacturing process, thereby substantially reducing our revenues. To date,
we have not experienced any material disruption in our operations as a result of
year 2000 problems, nor have we incurred any unplanned expenses to address year
2000 concerns.


FINANCIAL MARKET RISK

    Our financial market risk includes risks associated with international
operations and related foreign currencies. We anticipate that international
sales will continue to account for a significant portion of our consolidated
revenue. Our international sales are in U.S. dollars and therefore are not
subject to foreign currency exchange risk. Expenses of our international
operations are denominated in each country's local currency and therefore are
subject to foreign currency exchange risk; however, through June 30, 1999, we
have not experienced any significant negative impact on our operations as a
result of fluctuations in foreign currency exchange rates.

                                    BUSINESS

OVERVIEW

    We provide compact wireless communications systems using GSM, an
international standard for voice and data communications. We have pioneered what
we believe is the only commercially available system that provides all of the
infrastructure equipment and software necessary to support an entire wireless
network within a single, compact enclosure. We have designed our systems to
serve the following applications in a cost-effective manner:

    - WIRELESS OFFICES. Our systems allow wireless users in organizations such
      as large corporations, government entities and universities to maintain
      contact with the organization's private telephone network whether the
      users are in their offices, out of their offices or moving between
      locations.

    - COMMUNITY NETWORKS. Our systems enable wireless service providers to add
      capacity in heavy usage areas and to provide telephone service in
      previously unserved communities.

    Our core product, WAVEXpress, delivers a comprehensive set of wireless
network capabilities which are based on the GSM standard. WAVEXpress systems can
serve as:

    - a base station to receive and transmit voice and data signals over radio
      frequencies;

    - a switch to route voice and data signals to their correct destinations;

    - a base station controller to manage voice and data signals between the
      base station and the switch; or

    - any combination of these functions depending on our system's hardware and
      software configuration.

    Our all-in-one solution, the Network In A Box, provides the capabilities of
a complete wireless network in an enclosure approximately the size of a personal
computer tower.


    We market and sell our solutions around the world utilizing a three-pronged
sales strategy which includes selling to communications equipment providers, to
systems integrators which integrate our systems with the products of other
companies and through our own direct sales force. Since 1997 we have sold over
1,000 units which have been installed in 17 countries worldwide. We have
established a strategic alliance with Nortel Networks, which accounted for 51%
of our revenues in 1999 and which owns 22.4% of our outstanding shares, assuming
the exercise of all warrants. We have also recently entered into a strategic
alliance with Alcatel, which included their purchase of 4.3% of our outstanding
shares. These alliances include purchase and distribution agreements through
which both companies will market our products to their customers.



    In addition, in December 1999 we strengthened our strategic alliance with
Hutchison Telecommunications Group, which included the purchase by Holodeck
Limited, an affiliate of Hutchison Telecommunications Group, of 2 million
preferred shares at $8.00 per share, increasing their ownership to 7.2% of our
outstanding shares. We have also signed contracts with affiliates of Hutchison
Telecommunications Group to sell our products in Hong Kong and Sri Lanka.


INDUSTRY

RAPID GROWTH FOR MOBILE WIRELESS COMMUNICATIONS

    In recent years, worldwide demand for mobile wireless communications has
increased dramatically. According to International Data Corporation, the
worldwide wireless market is expected to grow from 303 million users in 1998 to
approximately 1.1 billion by 2003, a compounded annual growth rate of
approximately 29%. This rapid growth has been driven by the increasing
availability, functionality and affordability of wireless products and services.
The market for our systems is a subset of the worldwide wireless market. Since
the market for our systems is new and emerging, industry analysts have not
compiled reliable data about the size or growth rate of our target markets. Our
growth rate and the

                                       38
<PAGE>
growth rate of our target markets may not match the growth rate of worldwide
wireless markets in general.

    Changes in the worldwide regulatory environment, including the elimination
of monopolies for public communications services, privatization of
government-owned communications organizations and competitive licensing of radio
frequency spectrum by regulatory authorities, have led to an increase in the
number of communications service providers seeking to meet the rapidly growing
demand for mobile wireless communications. In Europe, for example, recent
European Union directives prohibit member countries from restricting competitive
access to mobile and local service after January 1, 1998. In the United States,
the Telecommunications Act of 1996 opened local telephone networks to new
competition. Similar trends in developing countries are creating significant
opportunities for new entrants in the communications market. This increasingly
competitive environment is rapidly driving down the prices that end-users pay
for services.

COMMUNICATIONS EQUIPMENT MARKET

    Wireless service providers are investing in expanding and upgrading their
networks to add capacity and keep pace with the demand for value-added services.
These investments are being driven by increased competition, strong subscriber
growth and new product innovation. Such investments enable wireless service
providers to extend geographic coverage, improve call quality, and deliver
enhanced features and services. Despite reductions in the cost of communications
equipment, service providers' capital budgets have continued to increase
substantially. According to Dataquest, the digital wireless communications
equipment market is expected to grow from approximately $31 billion in 1998 to
over $41 billion by the end of 2002. The market for our systems is a subset of
the digital wireless communications equipment market. Currently, there is no
reliable data about the size or growth rate of our target markets. Growth rates
experienced by the industry as a whole may not reflect growth rates that we, or
our target markets, will experience. In addition, recessionary conditions in
Asia have resulted in reduced demand for wireless communications systems.

GLOBAL SYSTEM FOR MOBILE COMMUNICATIONS STANDARD

    The GSM standard competes primarily with the code division multiple access
standard, or CDMA, the time division multiple access standard, or TDMA, and
analog standards. According to The Comprehensive Guide to Wireless Technologies,
an industry guide, all of the digital standards, including GSM, CDMA and TDMA,
offer clearer voice communications than the older analog standards. We believe
that digital standards will attract even more users in the future as functions
such as high-speed data communications become available. In addition to clearer
voice communications, the digital standards offer features not available with
analog standards. For example, GSM, CDMA and TDMA allow users to receive text
messages. Furthermore, the GSM standard allows users to roam across
international boundaries without an interruption in service. The TDMA and CDMA
standards do not allow this international roaming capability because those
phones do not have a removable personal identity card, which can be inserted in
phones using the local frequency range. Finally, CDMA does not have a maximum
number of calls it can handle at a given time. CDMA can accommodate additional
calls only by slightly degrading the quality of all ongoing calls. GSM and TDMA,
however, cannot expand the maximum number of calls to accommodate surges in
demand.


    According to International Data Corporation, GSM is the world's most widely
accepted digital wireless standard with 132 million users in 1998 and is
projected to grow to 556 million users by 2003. In 1998, GSM accounted for
approximately 44% of the world wireless market while CDMA, TDMA and analog
accounted for 8%, 6% and 31% of the world market, respectively. GSM is the
dominant standard in Europe as a result of the European Union's decision to
endorse a single unifying digital standard in the 1980s. In Asia, the rate of
acceptance of the GSM standard is growing rapidly as wireless service providers
have selected GSM to offer differentiated services and to increase capacity. On
November 1, 1999, the GSM Association and the Universal Wireless Communications
Consortium, the governing bodies of the GSM and TDMA standards, respectively,
announced an agreement to


                                       39
<PAGE>

jointly develop standards that enable GSM and TDMA systems to operate together.
International standards organizations are also working to develop the future
standard that will replace all three of these technologies.


    Early in the history of the wireless market, analog standards achieved a
strong presence in the United States while the GSM standard was being adopted in
Europe. According to Allied Business Intelligence, Inc., at the end of 1998
there were 3 million GSM users in the United States, which represented 4.3% of
all wireless users in the United States. Today, although the acceptance of the
GSM standard in North America is in its early stages, increased penetration of
the GSM standard is being driven by its ability to support international
roaming, and will be further driven by its advanced data transmission and
messaging capabilities. GSM has been adopted in North America by communications
service providers, including Microcell, OmniPoint, PacBell and VoiceStream. Both
CDMA and TDMA have a significant presence in the United States. Sprint PCS and
GTE have deployed CDMA and AT&T Wireless has deployed TDMA in the United States.


FUTURE WIRELESS STANDARD



    An international consortium of standards bodies is working to establish the
specifications of a future wireless standard, often referred to as the third
generation wireless standard, and to ensure its interoperability with existing
network standards. Since the installed base of wireless networks was not
designed to be interoperable with what we expect will be the future standard,
significant capital expenditures will be required to update them. We believe
wireless service providers will attempt to preserve their previous investments
in infrastructure and will seek incremental solutions that will facilitate
upgrading to the future wireless standard while ensuring interoperability among
disparate networks. Industry analysts expect the future standard to use the
Internet Protocol to enable high speed data transmissions over wireless
networks. The Internet Protocol is the networking standard used to communicate
voice and data across the Internet. Using the Internet Protocol for wireless
network access would provide potential cost-savings for wireless service
providers by allowing them to use the existing Internet infrastructure. We
expect these developments will increase the demand for cost-effective, flexible,
wireless networks that can be easily upgraded to the emerging future standard.


KEY DEVELOPING MARKET OPPORTUNITIES

    Rapid technological innovation in wireless communications is creating new
and varied market opportunities.

    WIRELESS OFFICES.  Wireless office networks combine the mobility and
flexibility of wireless communications with all of the features of traditional
telephone networks, and enable organizations such as large corporations,
government entities and universities to integrate their private office networks
with public wireless networks. This integration enables abbreviated dialing
while the user remains within the private office network. After the user leaves
the office building, incoming calls are routed to the user's mobile phone via
the public wireless network. Wireless office networks can increase productivity
by making it possible to reach employees through a single phone number at all
times, regardless of location, while providing significant cost savings for the
organization. The wireless office market enables wireless service providers to
expand their customer base, reduce subscriber turnover, provide customized
billing and establish a presence from which to offer wireless data networks. The
Yankee Group estimates the market for GSM wireless office networks will be
10.9 million distinct phone lines in 2002 in the European corporate market
alone. GSM wireless office networks compete with a digital European cordless
telephone standard known as DECT. In 1998, DECT had an installed base of
1.6 million wireless office lines in Europe compared to 410,000 for GSM.
However, unlike GSM, the DECT standard does not permit roaming outside the
office premises. While some handset vendors either offer or are considering
offering phones that support both DECT and GSM, the Yankee Group expects a
limited market for such a product for both technical and economic reasons. The
Yankee Group estimates the European market for DECT wireless office networks
will be 4.7 million wireless office lines in 2002.

                                       40
<PAGE>
    COMMUNITY NETWORKS.  Community networks enable the introduction of wireless
service to areas that are currently not served by wireless providers or that may
not have any telephone service. Wireless solutions such as wireless local loop
networks offer the most cost-effective way to provide telephone service to areas
with no current service. Wireless local loop networks are wireless
communications systems that connect users to the public telephone network using
radio signals as a substitute for traditional telephone connections. These
markets offer substantial growth potential due to the relatively low level of
rural and remote telephone service penetration and the continued need for
low-cost communications services. According to Frost & Sullivan, the wireless
local loop market is expected to grow from approximately $4.6 billion in 1998 to
$16.5 billion in 2002. Wireless solutions provide a high-value proposition in
developing countries since these solutions are generally less expensive than
establishing a traditional telephone infrastructure, according to Frost &
Sullivan. To succeed in the community networks market, we believe wireless
service providers need to employ network systems that minimize initial capital
expenditures while providing the flexibility to scale cost-effectively as demand
grows. In addition, wireless service providers need to minimize ongoing
operating costs, the largest of which are the charges associated with routing
calls through a central switch, where traditionally all calls are processed.

PRIMARY OBJECTIVES OF THE WIRELESS SERVICE PROVIDER

    To better serve their existing user base and to gain market share, wireless
service providers are focused on the following primary objectives:

    COST-EFFECTIVE NETWORK DEPLOYMENT.  The deployment of traditional wireless
networks requires significant capital expenditures. A typical wireless network
consists of a switch to route voice and data signals to their correct
destinations, multiple base station controllers to aggregate and manage voice
and data signals between the switch and the base station and many base stations
to transmit and receive voice and data signals over radio frequencies. Wireless
networks are typically designed to support large user bases. Service providers
need cost-effective ways to address smaller user bases. As service providers
face increasing price competition, they will depend on communications equipment
providers for cost-effective and technologically advanced infrastructure
systems.

    EXTENSION OF COVERAGE.  In the past, wireless networks have been deployed
primarily in urban centers and other heavy usage areas. Increasing demand for
improved service over wider geographic areas has prompted wireless service
providers to accelerate the expansion of their networks. In addition, wireless
service providers are deploying networks in locations where service has
previously been inadequate or prohibitively expensive to provide.

    IMPROVED QUALITY OF SERVICE.  Currently, wireless networks in metropolitan
areas are prone to a lower quality of service when heavy usage causes capacity
limits to be exceeded. Furthermore, wireless service in buildings, tunnels and
subways is often interrupted or unavailable. Similarly, wireless services in
remote areas are often limited due to the lack of a fully-developed wireless
infrastructure. Improving the quality of wireless service involves increasing
network capacity and capabilities to address current network constraints.

    VALUE-ADDED SERVICES.  The extreme competition faced by wireless service
providers requires them to offer differentiated, value-added services including
the ability to roam across regional, national and international boundaries
without an interruption in service, access to high-speed data transmission and
other features such as voicemail and caller ID. In order to address increasing
competitive pressures, wireless service providers must use flexible systems that
enable them to deploy numerous services in a timely and cost-efficient manner.


    As wireless service providers seek to achieve these objectives in an
extremely competitive market, they will increasingly require communications
equipment providers to develop wireless network solutions that enable the
flexible, cost-effective delivery of value-added services and that are capable
of being easily adapted to the future wireless standard.

THE INTERWAVE SOLUTION

    Our systems offer a number of important advantages to GSM service providers,
including:

COMPACT, FLEXIBLE AND MODULAR

    Our WAVEXpress products provide a comprehensive set of GSM network
capabilities. We believe that we provide the only commercially available system
that supports an entire GSM network within a single enclosure approximately the
size of a personal computer tower. The WAVEXpress system can serve as a base
station, base station controller, switch or any combination of these functions
depending on our system's hardware and software configuration. The WAVEXpress
product uses only four hardware modules which enables the system to be updated
and enhanced by simply exchanging specific hardware modules and upgrading
software. Our compact and modular system enables wireless service providers to
implement wireless office networks, to fill in coverage blind spots, to increase
capacity in heavy usage areas and to provide service to previously unserved
areas.

COST-EFFECTIVE NETWORK DEPLOYMENT AND OPERATION

    Our compact, flexible systems reduce both initial and incremental capital
expenditures for network deployment by wireless service providers. The flexible
nature of our products enable wireless service providers to rapidly add capacity
to their networks in a cost-effective manner. In addition, there are only four
WAVEXpress hardware modules, which result in reduced maintenance and training
costs, and a reduction in capital necessary to maintain spare parts in
inventory. Furthermore, we have a patented switch technology that allows the
network to determine whether a call should be directed to its destination by the
local network or by a central switch. This proprietary switch capability allows
a wireless service provider to reduce its dependence on the central switch and
increase network efficiency, resulting in lower operating costs.

INTEROPERABILITY WITH EXISTING GSM NETWORKS

    We maintain strict adherence to GSM standards to ensure that our systems are
compatible with other communications equipment providers' products. We have
proven our systems' interoperability in live networks with equipment from all
major communications equipment providers, including Alcatel, Ericsson, Lucent,
Nokia, Nortel Networks and Siemens. Our systems are also compatible with
existing private telephone systems. Interoperability enables wireless service
providers to upgrade their existing systems without having to replace their
entire network, facilitating the introduction of new capabilities and services
in a timely and cost-effective manner. We plan to maintain our systems'
interoperability despite changes to software, equipment configuration, network
design and upgrades to the various network standards.

RAPID TIME-TO-MARKET FOR NEW, VALUE-ADDED SERVICES


    Service providers using our wireless network systems can achieve rapid
time-to-market for new services which they can offer to new and existing users.
Our flexible design enables the system to be readily upgraded through simple
hardware additions and software reconfigurations. These features allow service
providers to decrease the implementation time required to offer new services to
customers. Our WAVEView products also allow for the control of all functions and
components of the network through a single management system. This enables
service providers to customize and expand service offerings to users without
deploying additional systems that require incremental training and testing. Our
expandable systems provide small, low-cost alternatives to expensive digital
communications infrastructure equipment. Furthermore, since our systems are
based on the Internet Protocol, we believe wireless service providers will be
able to easily adapt to the future wireless standard through simple software
upgrades or specific hardware replacements, instead of time-consuming deployment
of and costly investment in new network equipment.


                                       42

STRATEGY

    Our goal is to be the premier global provider of cost-effective, compact
wireless systems in targeted segments of the GSM market. The key elements of our
strategy include:

PROVIDE GSM WIRELESS OFFICE SYSTEMS

    We intend to provide cost-effective network systems for large organizations
such as corporations, universities and government entities. We have developed a
wireless office system that can function as a stand-alone network or as an
add-on to a new or existing network. Our system, and specifically our switch
technology, reduces costs for an organization by allowing a user's calls to any
campus to stay inside the organization's network. Nortel Networks and Alcatel
are actively marketing our wireless office system.


DELIVER FUTURE SOLUTIONS USING THE INTERNET PROTOCOL



    Our research and development efforts are focused on using our WAVEXpress
products to offer voice and data communications over the Internet. We plan to
capitalize on the flexibility of our system design to speed our customers'
transition to the emerging future standard once its specifications are
finalized. Our fully-functional, GSM voice communications system that uses the
Internet Protocol was demonstrated at the February 1999 GSM World Congress. We
expect this system to be commercially available in early 2000.


FURTHER PENETRATE EXISTING MARKET OPPORTUNITIES

    To date, our sales have been predominantly to wireless service providers
seeking to fill gaps in coverage, to increase capacity in heavy usage areas and
to provide wireless service to previously unserved areas. We believe that these
applications will continue to represent a significant market opportunity for our
systems. As our customers expand their networks, we plan to generate additional
orders. We intend to convert existing trials into large-scale commercial
deployments. Currently, we are involved in 16 trials in nine countries. We also
believe that our visibility as an early provider of network solutions that use
the Internet Protocol will lead to new deployments with new and existing
customers. For example, Alcatel will integrate our products that use the
Internet Protocol with their corporate office networking products and market
them through their enterprise solutions division.

STRENGTHEN AND EXPAND RELATIONSHIPS WITH COMMUNICATIONS EQUIPMENT PROVIDERS

    We intend to use our strategic relationships with communications equipment
providers such as Nortel Networks, Alcatel and Sagem to expand our geographic
coverage and increase the market share for our solutions. Our relationships with
these equipment providers allow us to benefit from their sales forces selling
our products and enable us to reach new customers and strengthen our position
with existing customers. Communications equipment providers bundle our solutions
with their products to address the needs of wireless service providers. Our
sales are also enhanced by equipment providers' abilities to offer service and
support for our systems. We believe that strengthening these relationships and
selectively establishing new relationships will help us to generate new sales.

USE TECHNOLOGICAL LEADERSHIP TO PROVIDE COMPETITIVE ADVANTAGES FOR WIRELESS
  SERVICE PROVIDERS

    We intend to use our leading-edge technology and intellectual property to
expand the capabilities of our network systems, streamline system upgrades and
simplify the purchasing process. Furthermore, we intend to update our equipment
to use the latest generation Power PC processor which will provide significantly
more processing power and enhance the service providers' ability to handle heavy
data usage. Upcoming enhancements to our systems include the implementation of a
Web-based system to manage wireless networks, which will provide all monitoring,
configuration and maintenance capabilities. This will enable rapid emergency
response and enhance overall system management. Further, our system will be
upgraded to use the latest generation PowerPC processor, giving our systems
significantly more processing power to enhance service providers' ability to
handle heavy data

                                       43
<PAGE>
usage. Finally, we intend to develop a Web-based system to enable service
providers to configure and purchase our solutions online, streamlining the
purchasing process and reducing related purchasing costs.

PRODUCT LINES

    We operate in a single business segment, the manufacture and sale of
compact, wireless communication systems. We have two product lines, WAVEXpress
and WAVEView.

<PAGE>
WAVEXPRESS

    Our core WAVEXpress product can house any combination of our switch, our
base station controller and our base station in a single compact enclosure. The
WAVEXpress system is approximately the size of a personal computer tower and
weighs less than 50 pounds. Our WAVEXpress product line represented 80% and 88%
of our net revenues for fiscal year 1999 and the three months ending
September 30, 1999, respectively.

    WAVEXCHANGE.  The WAVEXchange is a wireless switch that routes calls and is
designed to allow the network to process calls locally rather than at a central
switch, thereby reducing operating costs. The small size and configurability of
the WAVEXchange enable wireless service providers to deploy value-added services
rapidly. The WAVEXchange can be integrated with existing private telephone
networks. The WAVEXchange is the only GSM switch on the market that can act
either as a base station controller extension of a central switch or as a local
switch, on a call-by-call basis. The WAVEXchange uses standard GSM interfaces
and can be configured with up to 16 connections that support up to 4,000 users,
depending on the requirements of the network. We began shipping WAVEXchange
products in June 1998.

    WAVEXPRESS/BSC.  The WAVEXpress/BSC is a compact base station controller
that aggregates and manages the communications between the WAVEXpress/BTS and
the central switch or a local WAVEXchange switch. The wall-mountable
WAVEXpress/BSC, one of the smallest GSM base station controllers on the market,
connects to any central switch supporting the GSM standard. The WAVEXpress can
be configured with up to 16 connections depending on the requirements of the
network. We began shipping the WAVEXpress/BSC in December 1996.

    WAVEXPRESS/BTS AND TURBOWAVE/BTS.  The WAVEXpress/BTS is a base station
which accommodates up to three radios providing up to 22 simultaneous
communication channels. Versions of the WAVEXpress/BTS are available in all
three GSM frequency bands: 900 MHz and 1800 MHz for Europe and Asia and 1900 MHz
for the Americas. The WAVEXpress/BTS connects the user to the network with no
need for additional components. In addition, we offer a higher powered version
of the WAVEXpress/BTS, the TurboWAVE, which is available in two configurations.
The TurboWAVE offers broader geographic coverage with over 20 kilometers of
range. In covering a longer range, the TurboWAVE offers the service provider
benefits from increased coverage, greater reduction in transmission costs and
lower infrastructure costs per user. We began shipping the WAVEXpress/BTS in
December 1996 and the TurboWAVE/BTS in December 1997.

    NETWORK IN A BOX.  The Network In A Box offers the ability to support a
complete GSM network by integrating the switch, base station controller and base
station in a single WAVEXpress unit. The Network In A Box is designed for rapid
deployment and provides easy network expansion as usage and coverage
requirements increase. Ideally suited for wireless office networks, the Network
In A Box can support a stand-alone GSM network or it can integrate with most
private telephone networks to provide wireless GSM interoperability with a
corporate telephone network. We have a patented switch technology which allows a
single Network In A Box to act as a wireless extension to a private telephone
network and as an extension to a public wireless network on a call-by-call
basis. In remote and rural communities, the Network In A Box enables rapid
deployment of GSM capabilities. Since a high percentage of calls stay within the
local network, transmission costs to a central switch are minimized. Coverage
and capacity can be increased quickly and easily by adding WAVEXpress/BTS and
WAVEXpress/BSC units to the network. The Network In A Box can also serve as a
cost-efficient GSM starter network allowing wireless service providers to match
their infrastructure expenditures to usage growth. We began shipping the Network
In A Box in August 1998.

    WAVEXPRESS/BS PLUS.  The WAVEXpress/BS Plus combines the functions of a base
station controller and base station in a single product. A WAVEXpress/BS Plus
can support up to 600 users and up to three external WAVEXpress/BTS base
stations to serve up to 2,400 users.

                                       46
<PAGE>
WAVEVIEW

    WAVEVIEW.  The WAVEView is a management system for wireless service network
components. Our system simplifies the process of deploying new network
components, allowing the user to manage all aspects of wireless user profiles.
The WAVEView also allows wireless service providers to monitor network faults in
real-time and includes a comprehensive help function that guides users through
management tasks. We began shipping WAVEView in May 1998. Our WAVEView product
line represented 8% and 6% of our net revenue for fiscal year 1999 and the three

COMMUNICATIONS EQUIPMENT PROVIDERS

    NORTEL NETWORKS.  In March 1998, we entered into a five-year purchase and
distribution agreement with Nortel Networks. According to the terms of the
agreement, Nortel Networks has agreed to minimum purchase commitments of our
products on a quarterly basis through December 2000. The agreement requires that
we provide certain product features by various milestone dates. In addition, the
agreement precludes us from entering into similar agreements with Ericsson and
Nokia until December 31, 1999. After December 31, 1999, the restriction may be
terminated if the annual purchases by Nortel Networks in the calendar years
2000, 2001, or 2002 is less than 80% of their established minimum amounts.

    The agreement was amended in April 1999 with respect to Nortel Networks'
obligations to meet specific quarterly purchase commitments and to specify our
requirements to meet certain product development milestones that are important
to Nortel Networks. In the first six quarters since the original agreement was
executed, Nortel Networks has purchased over $12 million of our products.


    The agreement with Nortel Networks is one of a number of agreements executed
as part of a strategic alliance between our two companies. We also entered into
a patent license agreement whereby we acquired a license to certain patents held
by Nortel Networks and a technical information agreement whereby services for
systems testing facilities and equipment are provided. We have entered into a
number of financing transactions with Nortel Networks. Nortel Networks has made
an aggregate investment of $29.5 million in our company consisting of
$25.0 million in cash and delivery of license and technical information
agreements valued at $4.5 million. Assuming the exercise of all warrants held by
Nortel Networks, they own approximately 22.4% of our outstanding shares and will
own approximately 18.7% of our outstanding shares following the offering. See
"Certain Transactions".


    ALCATEL.  In July 1998, we entered into a two-year, non-exclusive purchase
and distribution agreement with Alcatel CIT. This agreement targeted specific
wireless service providers located in Western Europe where Alcatel CIT has a
significant supplier presence. Through September 30, 1999, Alcatel CIT had
purchased approximately $1.3 million of our products for initial testing along
with training and support services. In November 1999, we entered into a new
two-year, non-exclusive purchase and distribution agreement with Alcatel
Business Systems. Under this agreement, Alcatel Business Systems will integrate
our products, including those that use the Internet Protocol, with their
corporate office networking products and market them through their enterprise
solutions division. Alcatel Business Systems will provide us with $450,000 in
engineering funds. Alcatel Business Systems, which has made minimum purchase
commitments through December 2001 under the agreement, intends to resell our
products primarily to their corporate office customers. Under the agreement, we
agree to modify our products to contain certain features by various milestone
dates. In November 1999, Alcatel invested approximately $12.2 million in our
company by purchasing for cash approximately 1.5 million preferred shares at
$8.00 per share. As a result, Alcatel currently owns approximately 4.3% of our
outstanding shares.

    Our purchase and distribution agreements with Nortel Networks and Alcatel
provide that those companies will receive our lowest price for the volume of
products that they purchase from us. In both agreements, we have product
development obligations. If we do not meet these obligations, the quarterly
purchase commitments from these customers may be lowered or removed entirely. In
the past, we have missed product development milestones, resulting in decreases
in quarterly revenue obligations from Nortel Networks. See "Certain
Transactions--Series G Preferred Financing, Purchase and Distribution Agreement"
and "Certain Transactions--Series I1 Preferred Share Financing, Purchase and
Distribution Agreement."

    SAGEM.  In February 1999, we entered into a five-year, non-exclusive
purchase and distribution agreement with Sagem, S.A. Through September 1999,
Sagem had purchased approximately $500,000

                                       49

of our products for internal testing and sales demonstration. Sagem is not
currently obligated to meet any minimum volume purchase commitments.

SYSTEMS INTEGRATORS


    ADC TELECOMMUNICATIONS/MICROCELLULAR SYSTEMS.  In early 1997, we entered a
four-year, non-exclusive distribution agreement with ADC Telecommunications,
which led to nearly $9.8 million in revenue between 1997 and early 1999. In
May 1999, ADC Telecommunications assigned the agreement to Microcellular
Systems, a company started by former ADC Telecommunications mobile systems
division employees. Microcellular Systems, headquartered in the U.K., is
targeted at providing systems integration and service/support to specific key
wireless service providers in Western Europe. Microcellular Systems accounted
for $1.1 million of our revenue representing 21% of our net revenue for the
three months ended September 30, 1999. Microcellular Systems is not currently
obligated to meet any minimum volume purchase commitments. ADC
Telecommunications also provided us with development support and testing
services. Between July 1998 and March 1999, we worked closely with the company
to jointly develop products for the North American market. In conjunction with
this activity, ADC Telecommunications acquired 360,000 of our preferred shares
in exchange for development services valued at approximately $2.5 million. This
agreement concluded in May 1999.


    HANGZHOU TOPPER ELECTRIC CORPORATION.  In June 1999, we began selling our
products in China through HangZhou Topper Electric, a private company
incorporated in China. We have sold $2.5 million of our products to HangZhou
Topper Electric through September 30, 1999. Sales to HangZhou Topper Electric
represented 38% of our revenues in the three months ended September 30, 1999. We
intend to enter into a joint venture agreement with HangZhou Topper Electric
whereby the joint venture will manufacture our products for the China market, as
well as develop new products. HangZhou Topper Electric is not currently
obligated to meet any minimum volume purchase commitments.

DIRECT SALES

    We established a direct sales presence in Hong Kong in late 1995 and in
Paris in mid-1996. As a result, we have established a five-year cooperation
agreement with Telstra, headquartered in Australia, and a multi-year cooperation
agreement with France Telecom, headquartered in Paris, providing us with
information sharing opportunities with them. Through two GSM wireless service
providers, Hutchison Telecommunications Group, a unit of Hutchison Whampoa, and
Total Access Communications, a subsidiary of UCOM Group of Thailand, we have
deployed our network solutions in Hong Kong and Bangkok, respectively.


    HUTCHISON TELECOMMUNICATIONS GROUP.  We began deploying our products in Hong
Kong with Hutchison Telecommunications Group in 1997. In December 1999, we
executed a contract with an affiliate of Hutchison Telecommunications Group to
deploy our products in Sri Lanka. In addition, Holodeck Limited, an affiliate of
Hutchison Telecommunications Group and a wholly-owned subsidiary of Hutchison
Whampoa, purchased for cash 2 million preferred shares at $8.00 per share. As a
result, Holodeck Limited increased its beneficial ownership to 2.6 million
shares, or 7.2% of our outstanding shares, and will hold 5.9% of our outstanding
shares on completion of this offering. See "Certain Transactions--Series I1
Preferred Share Financing."



    In connection with our contract with an affiliate of Hutchison
Telecommunications Group to sell our products in Sri Lanka, we entered into an
exclusivity agreement in which we agreed not to sell our WAVEXchange and
WAVExpress products to any party in Sri Lanka other than Hutchison's affiliate
for a period of three years. This period will be extended two years if at the
end of the three year period Hutchison's affiliate has ordered equipment in the
aggregate value of $15 million. In this agreement, we also agreed not to sell
these products to any party in Mumbai, India until March 31, 2000. If by that
date Hutchison or its affiliate has placed an order for the products in the
aggregate


                                       50
<PAGE>

value of $6 million, we will not supply these products to any third party for
three years. This period will be extended two years if at the end of the three
year period Hutchison or its affiliate has placed an order in an aggregate value
of $15 million.


CUSTOMER SUPPORT--CUSTOMER ADVOCACY/ENGINEERING SERVICES

    Our support organization provides pre-sale, installation and post-sale
support to wireless service providers who have purchased systems directly from
us. We offer 24-hour telephone support seven days a week. We provide manuals and

offer an ongoing maintenance program for our products, which consists of product
enhancements, product updates and technical support. System operators may renew
maintenance and support on an annual basis by paying a maintenance fee. We also
provide extensive support to communication equipment providers and systems
integrators through product training, 24-hour help-desk support and emergency
problem resolution. In addition, we work closely with their first-line support
organizations to insure that they have the necessary skills and specific product
knowledge to assist their customers with installation, management and other
network support requirements.

    To maintain our technology leadership position, we focus our research and
development efforts on improving the functionality and performance of our
current products and developing new products. We obtain extensive development
input from our customers and actively monitor changes in the marketplace. We are
currently investing significant resources to:

    - develop high-speed data capabilities while significantly reducing
      manufacturing costs;

    - expand the capacity of our base station;

    - modify our WAVEView management system to adapt to the Internet Protocol;
      and

    - deliver product enhancements that allow communications equipment providers
      to offer additional value-added services required by wireless service
      providers.

    We believe our future success will depend, in part, on our ability to
continue to develop and introduce new products and enhancements to our existing
products. Our research and development expenditures totaled approximately
$14.2 million, $15.3 million and $14.2 million in the fiscal years ended
June 30, 1997, 1998 and 1999, respectively.

    We perform our research and product development activities in our Redwood
City and Hong Kong offices. As of September 30, 1999, our research and
development staff consisted of 75 full-time or contracted employees, that we
supplement from time to time with independent contractors and outside
development resources.

PROPRIETARY RIGHTS


    Our success and ability to compete depends in part upon our proprietary
technology. We rely on a combination of patent, copyright and trade secret laws
as well as non-disclosure agreements to protect our proprietary technology. We
currently hold 15 United States patents and have 13 United States patent
applications pending. Many of these patent applications have also been filed in
a number of other countries. We cannot be certain that patents will be issued
with respect to pending or future patent applications or that our patents will
be upheld as valid or will be sufficient to prevent the development of
competitive products. We seek to protect our intellectual property rights by
limiting access to the distribution of our software, documentation and other
proprietary information. In addition, we have entered into confidentiality
agreements with our employees and certain customers, vendors and strategic
partners. Despite these efforts, it may be possible for unauthorized third
parties to copy certain portions of our products, to design around our patents,
or to reverse-engineer or


                                       51
<PAGE>

otherwise obtain and use our proprietary information. In addition, we cannot be
certain that others will not develop substantially equivalent or superseding
proprietary technology, or that equivalent products will not be marketed in
competition with our products, thereby substantially reducing the value of our
proprietary rights. We are also subject to the risk of adverse claims and
litigation alleging infringement of the intellectual property rights of others.
In this regard, there can be no assurance that third parties will not assert
infringement claims in the future with respect to our current or future products
or that any such claims will not require us to enter into license arrangements
or result in protracted and costly litigation, regardless of the merits of such
claims.


    No assurance can be given that any necessary licenses will be available or
that, if available, such licenses can be obtained on commercially reasonable
terms. In addition, the laws of some countries do not protect our proprietary
rights to the same extent as do the laws of the United States. Accordingly, we
may not be able to protect our proprietary rights against unauthorized
third-party copying or use, which could significantly harm our business.

    In March, 1998, we acquired a license to certain GSM related patents held by
Nortel Networks in conjunction with Nortel Networks' equity investment in us. We
also have software license agreements with Lucent Technologies, TCSI, Inc.,
Trillium Digital Systems, Inc. and Wind River Associates which enable us to use
and modify the licensed software in our products.

MANUFACTURING

    We rely heavily on contract manufacturers to provide labor and
capital-intensive production capacity. We currently use two primary
contractors--PEMSTAR Inc.'s Quadrus contract manufacturing division and
GSS/ARRAY Technology.

    PEMSTAR, Inc. is responsible for manufacturing the majority of our
components and final system assembly. PEMSTAR has over 140,000 square feet of
manufacturing space in San Jose, California. Our initial manufacturing agreement
was signed in October 1995. GSS/ARRAY Technology is responsible for the
manufacture of our radio modules which they build for us pursuant to periodic
purchase orders. GSS/ARRAY has 100,000 square feet of total space in San Jose,
California and was recently acquired by ACT Manufacturing.

    While relying on contractors for most of our manufacturing needs, we also
conduct final assembly and systems test operations at our Redwood City facility.
These functions are expected to be transferred to our contract manufacturers by
the middle of calendar year 2000. Accordingly, our dependence on our
manufacturers will increase. Problems encountered during the consolidation or
future problems relating to our manufacturers' inability to meet our quality and
delivery specifications could harm our operating results.

    Since we typically have long sales cycles, we rely on a detailed sales
forecast to determine our production requirements and meet the ordering needs of
our contract manufacturers. We utilize the sales forecast to control our
inventory levels, and due to the hardware and software configuration of our
product line we are able to easily reconfigure our products in order to respond
to specific customer purchase orders in a timely manner. Our business is
generally not subject to any cyclicality, but rather our customers place
periodic purchase orders with us based on their requirements for our products.

    Our systems include a number of components which come from sole source
suppliers such as Lucent, Motorola and Xilinx. Our contract manufacturers
procure these components from distributors or directly from the sole source
manufacturer. We do not have any contracts with these sole source suppliers, but
we communicate with them frequently in order to insure the continuing
availability of components. Generally, if a manufacturer decides to discontinue
a critical component, it would provide enough time for us and our contract
manufacturers to locate alternative components. However, we might be required to
redesign our products or take other steps which could delay their availability.

                                       52
<PAGE>
    We plan to consolidate the manufacturing of all of our products with PEMSTAR
by the middle of calendar year 2000.

COMPETITION

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

    - conformity to industry standards;

    - breadth of product line;

    - implementation of additional product features and enhancements, including
      improvements in product performance, reliability, size and scalability;

    - cost;

    - ease of deployment;

    - sales and distribution capability; and

    - and technical support and service.

    We expect that competition in each of our markets will increase in the
future. We currently compete against GSM communications equipment providers such
as Ericsson, Lucent, Motorola, Nokia, and Siemens. We also compete with the
TDMA, CDMA, DECT and wireless local loop product offerings from these same
communications equipment providers and expect that a number of them will develop
competing data communications products and technologies in the near future. We
also compete with the CDMA product offerings of Samsung and LG. In addition, we
compete with the wireless local loop product offerings of Hughes and NEC. While
Alcatel and Nortel Networks are our customers, we do compete in several market
applications. Most of these leading GSM communications equipment providers focus
on solutions that address large numbers of subscribers. Equipment providers are
beginning to focus on markets with smaller subscriber bases as we do currently.
All of the major GSM communications equipment providers have at least partial
GSM solutions that address our target markets.

    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 to preclude us from making or selling certain products or that
competitive pressures we face will not seriously harm our business and results
of operations.

EMPLOYEES

    As of September 30, 1999, we employed or contracted 166 full-time persons,
including 20 in operations, 50 in marketing, sales and customer support, 75 in
research and development and 21 in finance and administration. Of these
employees, 14 were contract employees who were primarily engaged in software
engineering and systems integration and testing. None of our employees is
represented by a labor union and we have experienced no work stoppages to date.
We believe our relationship with our employees is good.

FACILITIES


    Our principal administrative and engineering facilities are located in
leased facilities totaling approximately 28,500 square feet located in Redwood
City, California. We have recently signed a lease for approximately 56,000
square feet in Menlo Park, California for our principal administrative and
engineering facilities. The five-year lease commenced December 15, 1999. We
expect to sublet the premises in Redwood City following our relocation in early
2000 until the expiration of our Redwood


                                       53
<PAGE>

City lease in 2002. However, we cannot be certain that we will be successful in
subletting the facilities or that subletting the facilities will allow us to
cover all of our current costs under the lease. In addition, we lease sales,
service and systems testing facilities totaling approximately 5,900 square feet
in Hong Kong and approximately 3,500 square feet in Paris, France. The leases
for the Hong Kong facilities expire in 2001 and 2003 and the lease for the Paris
facility expires in 2005.


GOVERNMENT REGULATION

    We must obtain regulatory approval for our products to be used in some
jurisdictions. Regulators in Europe, Asia and North America have approved our
products as being compliant with GSM standards. We may sell and deploy our
products in these jurisdictions and in other jurisdictions which rely on these
jurisdictions for approvals. In some cases, specific country compliance testing
may be required. The delays inherent in this regulatory approval process may
cause the rescheduling, postponement or cancellation of the installation of our
products by our customers which, in turn, may significantly reduce sales of
products to such customers.

    We are also subject to US government export controls. We rely on our
customers to inform us when they plan to deliver our products to other countries
and we regularly inform our customers of the export controls with which they
must comply.

LEGAL PROCEEDINGS

    On June 28, 1999, we filed a complaint against JetCell Corporation in the
United States District Court for the Northern District of California (INTERWAVE
COMMUNICATIONS INTERNATIONAL LTD., V. JETCELL CORPORATION, Case No. C99-3125)
alleging misappropriation of trade secrets and infringement of United States
Patent Nos. 5,734,979 and 5,818,824. One of the founders of JetCell Corporation
is a former employee of interWAVE and JetCell also employs another former
employee of interWAVE. The complaint seeks injunctive relief and damages. On
July 19, 1999, JetCell filed an answer to the complaint and a series of
counterclaims against us. The answer denied the allegations made in the
complaint and the counterclaims included allegations against us of unfair trade
practices, unfair competition, defamation, patent misuse and patent invalidity.
The answer and counterclaims seek injunctive relief, damages, invalidation of
our patents and a dismissal of the complaint. On August 9, 1999, we filed an
answer to JetCell's counterclaims denying the allegations made in the
counterclaims. We are unable to predict the outcome of the litigation and do not
expect it to be resolved in the near future. However, if we are unable to settle
these proceedings in a satisfactory manner, the legal proceedings may be time
consuming and expensive and the outcome could be adverse to us. If the outcome
is adverse to us, we would experience more competition in our markets and may be
required to license technology required for our products, either of which could
harm our business and financial results.

    We may from time to time become a party to various legal proceedings arising
in the ordinary course of our business. However, other than as described above,
we are not currently involved in any material legal proceedings.

BOARD OF DIRECTORS

    We currently have eight directors. Our directors hold office until the next
annual meeting of shareholders or until their successors are duly elected or
appointed.  All eight of our directors were elected pursuant to voting
agreements between us and certain of our shareholders. The most recent voting
agreement required that the parties to the agreement vote all of their shares so
as to elect as directors two persons designated by holders of the common shares,
one person designated by EXCELlink Corporation, one person designated by
Mainwell Corporation, one person designated by Sasson International Holdings,
Inc., one person designated by Mayfield VII and Mayfield Associates Fund II, one
person designated by Morgan Stanley Venture Capital Fund II and one person
designated by Nortel Networks. All of the voting agreements terminate on the
effective date of our initial public offering. Following this offering, our
board of directors will be divided into three classes. The

                                       57
<PAGE>
directors in each class will serve for a three-year term, one class being
elected each year by our shareholders.

BOARD COMMITTEES

    The audit committee currently consists of Messrs. Harding and Wang. The
audit committee reviews our annual audit and supervises independent auditors
that review the company's internal accounting procedures and financial
management practices.

    The compensation committee currently consists of Messrs. Fong, Tsang and
Wang. The compensation committee makes recommendations concerning salaries,
stock options, incentives and other forms of compensation for directors,
officers and other employees of our company. The compensation committee also
administers our common share plans.

DIRECTOR COMPENSATION

    Our 1999 option plan provides for grants of options to purchase common stock
to our directors who are not employees. Non-employee directors will receive
annual 10,000 share option grants annually on an ongoing basis, commencing with
our 2001 annual meeting. In November 1999, each of our non-employee directors
received an option to purchase 50,000 common shares at an exercise price of
$7.60 per share. In addition, our directors are reimbursed for expenses incurred
in connection with attending board and committee meetings.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    None of the members of the compensation committee is currently, or has been
at any time since our formation, one of our officers or employees. During the
fiscal year ended June 30, 1999, no executive officer of our company served as a
member of the board of directors or compensation committee of any entity that
has one or more officers serving as a member of our board of directors or
compensation committee.

EXECUTIVE OFFICERS

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

EXECUTIVE COMPENSATION

    In fiscal year 1999, we paid an aggregate $917,582 in cash compensation to
the directors and officers named under the caption "Directors, Executive
Officers and Key Employees," as a group.


    At January 18, 2000, our directors and officers, as a group, held options to
purchase a total 2,156,007 common shares, at exercise prices ranging from $0.30
to $7.60 per share. These options are scheduled to expire on various dates
between February 15, 2006 and November 19, 2009.

installments over the four years of service following the date grant. 40,000 of
the options vest upon achievement of revenue targets.


    In accordance with the rules of the SEC, the above shows the potential
realizable value over the term of the option (the period from the grant date to
the expiration date) based on assumed rates of share price appreciation of 5%

future share price. Actual gains, if any, on option exercises will depend on the
future performance of our common shares.

    The following table sets forth information with respect to stock options
granted from the end of the last fiscal year until January 18, 2000 to the

EMPLOYMENT AGREEMENTS

    In June 1999, we entered into an employment agreement with Thomas Hubbs, our
Executive Vice President and Chief Financial Officer. The agreement provides for
an annual base salary of $260,000 and quarterly bonuses up to 30% of his then
annual salary per year, beginning in fiscal year 2000, upon meeting corporate
objectives established by the board of directors. The agreement also provides
Mr. Hubbs with incentive stock options to purchase an aggregate of 100,000
common shares subject to time-based vesting over a four-year period. The
agreement provides that Mr. Hubbs is an employee at will, which means that his
employment may be terminated at any time at our sole discretion. The agreement
also provides that if Mr. Hubbs' duties or position is changed in a detrimental
manner towards him upon a sale of our assets or merger with or into another
entity, we will owe him severance of one year salary and accelerate the vesting
of some of his option shares.

    In September 1999, we entered into an employment agreement with Ian
Sugarbroad, our President and Chief Operating Officer. The agreement provides
for an annual base salary of $250,000 and quarterly bonuses up to $50,000 per
year upon meeting revenue and expense targets. The agreement also provides
Mr. Sugarbroad with incentive stock options to purchase an aggregate of 300,000
common shares subject to time-based vesting over a four-year period. In
addition, Mr. Sugarbroad may earn up to 50,000 common shares for each of the
next four years in quarterly bonuses. The agreement provides that
Mr. Sugarbroad is an employee at will, which means that his employment may be
terminated at any time at our sole discretion. If we terminate Mr. Sugarbroad's
employment without cause, we must pay him up to 100% of his annual salary for
one year. The agreement also provides that if Mr. Sugarbroad's duties or
position is changed in a detrimental manner towards him upon a sale of our
assets or a merger with or into another entity, we will owe him severance of one
year salary and accelerate the vesting of some of his option shares.

EMPLOYEE BENEFIT PLANS

1999 OPTION PLAN


    Our option plan was approved by our board in September 1999 and will be
submitted to our shareholders for their approval prior to the date of this
offering to become effective on the date of this offering. Our option plan
provides for the grant of incentive stock options to employees and for the


                                       61
<PAGE>

grant of nonstatutory stock options and share purchase rights to employees,
directors and consultants. Unless terminated sooner, this option plan will
terminate automatically in 2009. The 1999 option plan will have 1,818,867
initial shares available for grant, which were the reserved and unissued shares
under the 1994 stock plan The amount reserved under the option plan will
automatically increase at the end of each fiscal year by the lesser of 2,000,000
shares or 4.0% of outstanding shares on such date or an amount determined by the
board.


    The option plan may be administered by the board or a committee of the
board, which committee must, in the case of options intended to qualify as
"performance-based compensation" consist of two or more "outside directors." The
administrator of the option plan has the power to determine the terms of the
options or share purchase rights granted, including the exercise price of each
option or share purchase right, the number of shares subject to each option or
share purchase right, the exercisability of options, and the form of
consideration payable upon exercise of an option or share purchase right. In
addition, the administrator has the authority to amend, suspend or terminate the
option plan, provided that no action by the administrator may affect any of the
common shares previously issued and sold or any option previously granted under
the option plan.

    Options and share purchase rights granted under the option plan are not
generally transferable by the optionee, and each option and share purchase right
is exercisable during the lifetime of the optionee only by the optionee. Options
granted under the option plan must generally be exercised within three months
after the end of optionee's status as our employee, our director or as our
consultant. In the case of termination by reason of death or disability, an
option will generally remain exercisable for a period of 12 months. In no event
may an option be exercised later than the expiration of the option's term.
Options generally vest over a 4-year period at a rate of 1/4 of the shares
subject to the option after the first year and 1/48 of the shares subject to the
option each following month.

    In the case of share purchase rights, unless the administrator determines
otherwise, the restricted share purchase agreement entered into at the time a
share purchase right is exercised grants us a repurchase option exercisable upon
the voluntary or involuntary termination of the purchaser's employment or
consulting relationship with us for any reason including death or disability.
The purchase price for shares repurchased pursuant to the restricted share
purchase agreement is the original price paid by the purchaser and may be paid
by cancellation of any indebtedness of the purchaser to us. The administrator
determines the rate at which a repurchase option will lapse.

    The administrator determines the exercise price of nonstatutory stock
options granted under the option plan, but with respect to nonstatutory stock
options intended to qualify as "performance-based compensation" within the
meaning of Section 162(m) of the Internal Revenue Code, as amended, the exercise
price must at least be equal to the fair market value of the common shares on
the date of grant. The exercise price of all incentive stock options granted
under the option plan must be at least equal to the fair market value of the
common shares on the date of grant and the term of such option may not exceed
ten years. With respect to any participant who owns shares possessing more than
10% of the voting power of all classes of our outstanding capital shares, the
exercise price of any incentive stock option granted must equal at least 110% of
the fair market value on the grant date and the term of such incentive stock
option must not exceed five years. The administrator determines the term of all
other options.

    Commencing with our 2001 annual meeting of shareholders, each of our
non-employee directors will automatically be granted an option to purchase
10,000 shares each year following the date of our annual shareholder's meeting,
if on such date he or she will have served on the board of directors for at
least the previous 6 months. Each option will have a term of 10 years and the
exercise price will be 100% of the fair market value per common share on the
date of grant. Each option will vest as to 1/12

                                       62
<PAGE>
of the shares each month following the date of grant, provided the optionee
still serves as a director on those dates.

    The option plan provides that in the event that we merge with or into
another corporation, sell substantially all of our assets or enter a similar
transaction, the successor corporation will assume or substitute each option or
right. If the outstanding options or rights are not assumed or substituted, the
administrator will provide notice to the optionee that he or she has the right
to exercise the option or right as to all of the shares subject to the option or
right, including shares which would not otherwise be exercisable, for a period
of 15 days from the date of the notice. The option or right will terminate upon
the expiration of the 15-day period.

1999 EMPLOYEE SHARE PURCHASE PLAN

    Our employee share purchase plan was adopted by the board in September 1999
and will be submitted to our shareholders for their approval prior to the date
of this offering, to become effective on the date of this offering. A total of
300,000 of our common shares have been reserved for issuance under the employee
share purchase plan. The amount reserved under the employee share purchase plan
will be increased automatically at the end of each fiscal year in the amount of
the lesser of 200,000 shares, 0.5% of the outstanding shares on such date or an
amount determined by the board.

    The board of directors or a committee appointed by the board of directors
administers the employee share purchase plan. The board of directors or its
committee has full and exclusive authority to interpret the terms of the
employee share purchase plan and determine eligibility.

    The employee share purchase plan contains successive, overlapping 24-month
offering periods. Each offering period includes four 6-month purchase periods.
The offering periods generally start on the first trading day on May 1 and
November 1 of each year, except for the first offering period, which commences
on the date of this offering and ends on the last trading day before
October 31, 2001.

    Employees are eligible to participate in our employee share purchase plan if
they are customarily employed by us or any participating subsidiary for at least
20 hours per week and more than five months in any calendar year, although any
employee who would own shares representing 5% or more of the total combined
voting power or value of all classes of our capital shares may not participate
in the employee share purchase plan. In addition, no employee of ours may be
granted an option to purchase shares under the plan if that person's right to
purchase shares under all of our employee share purchase plans accrues at a rate
that exceeds $25,000 worth of shares for each calendar year. The employee share
purchase plan permits participants to purchase common shares through payroll
deductions of up to 15% of the participant's compensation which includes the
participant's base straight time gross earnings, commissions, payments for
overtime, profit sharing payments, shift premium payments, incentive
compensation, incentive payments and bonuses. The maximum number of shares a
participant may purchase during any single offering period is 10,000 shares.

    Amounts deducted and accumulated under the employee share purchase plan are
used to purchase common shares at the end of each 6-month purchase period. The
price of shares purchased under the employee share purchase plan is 85% of the
lower of the fair market value of the common shares at the beginning of the
offering period or after a purchase period end. If the offering period commences
on the date of this offering, the price of the shares purchased shall be the
price to the public of the shares offered in this offering. In the event the
fair market value at the end of a purchase period is less than the fair market
value at the beginning of the offering period, participants will be withdrawn
from the current offering period following their purchase of shares on the
purchase date and will be automatically re-enrolled in a new offering period.
Participants may end their participation at any time during an offering period
and will be paid their payroll deductions to date. Participation ends
automatically upon termination of employment with us. Rights granted under the
employee share

                                       63
<PAGE>
purchase plan are not transferable by a participant other than by will, the laws
of descent and distribution, or as otherwise provided under the employee share
purchase plan.

    The employee share purchase plan provides that, in the event that we merge
with or into another corporation or sell substantially all of our assets, each
outstanding right to purchase shares under the employee share purchase plan
during the offering period then in progress may be assumed or substituted for by
the successor corporation. If the successor corporation refuses such assumption
or substitution, the offering period then in progress will be shortened and a
new purchase date will be set at or prior to the closing of that transaction
after which time the employee share purchase plan will terminate.

    The employee share purchase plan will terminate in 2009. The board has the
authority to amend or terminate the employee share purchase plan, except that no
such action may adversely affect any outstanding rights to purchase shares under
the employee share purchase plan.

1994 STOCK PLAN

    This stock plan was adopted on July 13, 1994. This plan provides for the
grant of incentive stock options to our employees, including employee directors,
and nonstatutory stock options and stock purchase rights to our employees,
directors and consultants. We have reserved 10,730,000 common shares for
issuance under this plan. As of September 30, 1999, options to purchase
5,130,509 common shares were outstanding at a weighted average exercise price of
$1.10, 2,991,686 shares had been issued upon exercise of outstanding options,
and 2,607,805 shares were available for future grant and have been added to the
1999 option plan.

    This stock plan is administered by our board of directors or by a committee
appointed by our board of directors. The administrator determines the terms of
options granted under the option plan, including the number of shares subject to
the option, exercise price, term and exercisability. Unless terminated earlier
by our board of directors, this option plan shall terminate on July 12, 2004.

    Incentive stock options granted under the option plan must have an exercise
price of at least 100% of the fair market value of the common shares on the date
of grant and at least 110% of the fair market value in the case of an optionee
who holds more than 10% of the total voting power of all classes of our shares.
Nonstatutory stock options granted under the option plan must have an exercise
price of at least 85% of the fair market value of the common shares on the date
of grant. If an optionee holds more than 10% of the voting power of all classes
of our capital shares, any options granted to that optionee must have an
exercise price of at least 110% of the fair market value of the common shares on
the date of grant. Payment of the exercise price may be made in cash or other
consideration as determined by the administrator. The term of an incentive stock
option cannot exceed 10 years, and the term of an incentive stock option granted
to a holder of more than 10% of our voting power cannot exceed five years.

    No option may be transferred by the optionee other than by will or the laws
of descent or distribution. Each option may be exercised during the lifetime of
the optionee only by the optionee or permitted transferee. Options granted under
the option plan generally must be exercised within 90 days after termination of
the optionee's status as our employee, our director or our consultant, or within
6 months if termination is due to the disability of the optionee or 12 months if
termination is due to the death of the optionee, but in no event later than the
expiration of the option's term.

    In the event that we merge with or into another corporation, or sell
substantially all of our assets, each outstanding option may be assumed or an
equivalent option substituted by the successor organization. However, if the
successor corporation does not agree to assume or substitute the option, the
option will terminate. Our board of directors has the authority to amend or
terminate the option plan provided that no action that impairs the rights of any
holder of an outstanding option may be

                                       64
<PAGE>
taken without the holder's consent. In addition, our shareholders must approve
any modification to the option plan.

401(K) PLAN

    In 1995, we adopted a 401(k) plan covering our full-time employees located
in the United States. The 401(k) plan is intended to qualify under
Section 401(k) of the Internal Revenue Code, so that contributions to the 401(k)
plan by employees or by us, and the investment earnings thereon, are not taxable
to employees until withdrawn from the 401(k) plan, and so that we can deduct our
contributions, if any, when made. Pursuant to the 401(k) plan, employees may
elect to reduce their current compensation by up to the lesser of 20% of their
annual pre-tax gross compensation or the statutorily prescribed annual limit of
$10,000 in 1999 and to have the amount of the reduction contributed to the
401(k) plan. Matching contributions by us, if any, are vested when made; all
other contributions, and earnings on such contributions, are at all times fully
vested. We did not contribute to the plan in the fiscal year ending June 30,
1999, but have agreed to match up to $1,000 of employee contributions in a
calendar year beginning with the fiscal year ending June 30, 2000.

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY

    Our bye-laws provide that we shall indemnify our directors, officers,
employees and other agents but for acts of fraud and dishonesty on the part of
indemnified parties. In addition, our bye-laws provide that our shareholders
agree to waive any claims or right of actions the shareholders may have against
any of our directors or executive officers on account of any action taken by the
directors or executive officers in their capacity for us. This waiver does not
apply to claims arising under the U.S. federal securities laws. Our bye-laws
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 our bye-laws expressly permit indemnification.

    We will be entering into agreements to indemnify our directors and executive
officers, in addition to the indemnification provided for in our bye-laws. These
agreements, among other things, will indemnify our directors and executive
officers for certain expenses including attorneys' fees, judgments, fines and
settlement amounts incurred by any director or executive officer in any action
or proceeding, including any action by or in our right arising out of that
person's services as a director, officer, employee, agent or fiduciary for us,
any subsidiary of ours or any other company or enterprise to which the person
provides services at our request. The agreements do not provide for
indemnification in cases where

    - the claim is brought by the indemnified party;

    - the indemnified party has not acted in good faith;

    - the claim arises under section 16(b) of the exchange act; or

    - the indemnified party has engaged in acts, omissions or transactions for
      which the indemnified party is prohibited from receiving indemnification
      under the agreement or applicable law.

We believe that these provisions and agreements are necessary to attract and
retain qualified persons as directors and executive officers. It is the position
of the SEC that indemnification for liabilities arising under federal or state
securities laws is against public policy and not enforceable.

    At present, there is no pending litigation or proceeding involving any of
our directors or officers in which indemnification is required or permitted, and
we are not aware of any threatened litigation or proceeding that may result in a
claim for such indemnification.

                              CERTAIN TRANSACTIONS


SERIES G PREFERRED FINANCING

SERIES G PREFERRED SHARES AND WARRANTS

    In March and April 1998, we sold 3,714,286 Series G preferred shares and a
warrant to purchase 2,000,000 shares of Series G preferred shares at $7.00 per
share to Nortel Networks for an aggregate purchase price of $24,500,000. We
incurred financing costs of $1,756,000 in association with this financing.

    Consideration of the purchase price consisted of:

    - a cash payment by Nortel Networks of $20,000,000

    - the signing and delivery of a technology patent license agreement by
      Nortel Networks granting us a license to certain Nortel Networks' patents
      with a value of $1,000,000 and;

    - the signing and delivery of a technical information agreement by Nortel
      Networks granting us access to Nortel Networks' technical assistance,
      testing services and other documentation and support with a value to us of
      $3,500,000

    The warrant to purchase 2,000,000 Series G preferred shares at $7.00 per
share expires on the earlier of March 27, 2001, the closing of an initial public
offering or a sale of all or substantially all of our assets. Nortel Networks
has notified us of its intent, which may be withdrawn, to exercise this warrant
at the time of this offering. We therefore assumed the exercise and subsequent
conversion into common shares as indicated throughout this filing.

    The Series G preferred shares contain a $7.00 per share liquidation
preference and converts to common shares on a one-to-one basis. Concurrently
with the sale of the Series G preferred shares, Nortel Networks entered into a
registration rights agreement with us providing the registration rights
described in "Description of Share Capital--Registration Rights" and a voting
agreement providing for the election of our board of directors. Additional
information regarding the voting agreement is provided below.


    Assuming the exercise of all warrants held by Nortel Networks, they
currently own approximately 22.4% of our outstanding common shares and will own
18.7% of our outstanding common shares following the offering. Pascal R. Debon,
President of Wireless Solutions for Nortel Networks, is a member of our board of
directors. Sales to Nortel Networks represented 51% and 18% of our net revenues
for fiscal years 1999 and the three months ending September 30, 1999,
respectively.


PATENT LICENSE AGREEMENT

    The patent license agreement provides us with a license to certain patents
held by Nortel Networks. The patent licenses continue in one year periods and
are subject to renewal at the end of each year with the consent of Nortel
Networks and us.

    Nortel Networks may terminate the patent technology license agreement if it
is assigned by us to a third party. However, Nortel Networks may not terminate
the agreement if the third party is not a competitor of Nortel Networks, we
transfer all or substantially all of our assets to the third party, the
financial condition of the third party is not substantially worse than ours at
March of 1998 and the third party agrees to assume all of our obligations under
the patent technology license agreement. If the patent technology license
agreement is terminated due to assignment to a third party prior to the fourth
anniversary of its March 27, 1998 effective date, Nortel Networks shall refund,
at its option, to us the amounts set forth below either in cash or our shares.
However, Nortel Networks shall pay the refund in cash if the fair market value
of one share of our Series G preferred shares is less than six dollars and six
cents per share.

TECHNICAL INFORMATION AGREEMENT

    The technical information agreement provides us access to Nortel Networks'
technical assistance and testing services and other support and technical

upon termination of the purchase and distribution agreement signed concurrently
with the technical information agreement.

    Nortel Networks may terminate portions of the technical information
agreement relating to technical information, technical assistance and technology
development if it is assigned by us to a third party. However, Nortel Networks
may not terminate any portion of the agreement if the third party is not a
competitor of Nortel Networks, we transfer all or substantially all of our
assets to the third party, the financial condition of the third party is not
substantially worse than ours at March of 1998 and the third party agrees to
assume all of our obligations under the technical information agreement.

    If a portion of the technical information agreement is terminated due to
assignment to a third party prior to the fourth anniversary of its March 27,

PURCHASE AND DISTRIBUTION AGREEMENT

    Concurrently with the sale of Series G preferred shares, Nortel Networks
entered into a purchase and distribution agreement with us in which Nortel
Networks agreed to purchase goods and services according to certain
specifications and we agree to supply the goods and services.

    This agreement establishes minimum amounts of goods to be purchased by
Nortel Networks for each quarter starting in June 1998 and ending in December
2000. The agreement requires that we provide specified product features by
various milestone dates. The minimum amounts of goods to be purchased can be
periodically adjusted to reflect the prevailing conditions of markets for the
goods. If the established minimum amount of goods for each quarter above is not
purchased, Nortel Networks

                                       67
<PAGE>
shall pay us a percentage of the shortfall of goods not purchased for that
quarter. We shall credit Nortel Networks in the subsequent quarter the amount
paid for Nortel Networks' shortfall if Nortel Networks makes up the shortfall
with an excess in orders in the following quarter.

    This agreement further provides that until December 31, 1999 we shall not
enter into a purchase and distribution agreement with Nokia or Ericsson for
products developed using information contained in or as a result of the
technical information or purchase and distribution agreements with Nortel
Networks. After December 31, 1999, the above restriction shall be terminated
only if the annual purchase by Nortel Networks for the calendar years 2000, 2001
and 2002 is less than eighty (80%) percent of the established minimum amounts.

    This agreement between us and Nortel Networks may be immediately terminated,
in whole or in part, by either party if the other party fails to remedy a breach
of an order within 60 days of written request, declares or seeks bankruptcy
protection or ceases to carry on business.

AMENDMENT OF BYE-LAWS

    In connection with the sale of Series G preferred shares, we amended our
bye-laws to require Nortel Networks' consent before an increase to the
authorized number of Series G preferred shares.

    Our bye-laws were further amended to provide for the following until the
closing of an initial public offering:

    - Prohibit us from engaging, directly or indirectly, in any business other
      than the microcellular business except with the prior consent of Nortel
      Networks or, if the limited exclusivity provisions contained in the
      purchase and distribution agreement have terminated, with the prior
      consent of a majority of directors who are neither officers nor employees

    - Prohibit us from acquiring stock or making an investment in any person
      engaged primarily in the compact wireless communications systems business
      involving an aggregate of $5,000,000 except with the prior consent of
      Nortel Networks or, if the limited exclusivity provisions contained in the
      purchase and distribution agreement have terminated, with the prior
      consent of a majority of directors who are neither officers nor employees

    - Prohibit us from acquiring stock or making an investment in any person NOT
      engaged primarily in the compact wireless communications systems business
      involving an aggregate of $1,000,000 except with the prior consent of
      Nortel Networks or, if the limited exclusivity provisions contained in the
      purchase and distribution agreement have terminated, with the prior
      consent of directors who are neither officers nor employees

    - Prohibit us from selling technology or assets described in the patent
      license agreement and the technology license agreement outside the
      ordinary course of business except in compliance with the provisions
      contained in those agreements or with the prior consent of Nortel Networks

    - Prohibit us from entering into any transaction with any person that is the
      beneficial owner or is affiliated with a beneficial owner of 5% or more of
      the outstanding voting shares except with the prior written consent of
      Nortel Networks

    - Require a majority of our board members to consent to its budget for each
      fiscal year, and any material expenditures made beyond the limits set by
      such budget

    - Prohibit us from incurring any debt in an amount exceeding $1,000,000
      except with the prior approval of two-thirds of its board members

    - Require our bye-laws to provide for a board consisting of nine members, at
      least seven of whom will be neither officers nor employees. Further, a
      majority of the directors holding office will be necessary for a quorum,
      provided that if the number of directors holding office is less than five
      and the director nominated by Nortel Networks remains in office, then
      Nortel Networks' director must be present to constitute a quorum

                                       68
<PAGE>
    - Require our compensation committee to approve any employment agreement
      with any officer or other employee under which the total compensation
      package may be expected to exceed $250,000

    - Require transactions taken by any of our majority-owned subsidiaries to be
      subject to the same provisions described above.

LOAN AGREEMENT

    In December 1998 we entered into a loan agreement with Nortel Networks in
which we borrowed $1,400,000 at 12% annual interest. The loan's maturity date
was the earlier of:

    - February 21, 1999

    - the date on which we closed a public offering or obtained net cash
      proceeds in the sale of assets or a financing of $6,000,000

    - the date of the signing and delivery of an agreement providing for our
      acquisition by another company; or

    - a change in control of our management

    We were able to pay the accrued interest on the note but we were not able to
repay the principal amount borrowed at the maturity date of February 21, 1999
causing a default under the terms of the loan agreement. To remedy the default,
on April 22, 1999, we issued to Nortel Networks a warrant to acquire 24,000
common shares at $1.15 per share. The warrant expires on the earlier of
April 22, 2002 or the closing of an initial public offering.

    The principal balance of $1,400,000 borrowed in the loan agreement was
applied as payment for Nortel Networks' participation in our March 1999,
convertible loan and warrant financing. As a result, Nortel Networks' $1,400,000
became a loan to us under the convertible loan and warrant financing. Additional
information regarding our convertible loan and warrant financing is provided
below.

CONVERTIBLE NOTE AND WARRANT FINANCING


    Between March 1999 and June 1999, we entered into convertible note and
warrant agreements with 106 investors, all of which were existing shareholders,
in which we borrowed an aggregate of $12,691,830 at 8% annual interest. In
connection with the convertible note financing, we granted the investors
warrants to purchase an aggregate of 6,345,939 common shares at a purchase price
of $0.70 per share. These warrants expire at various times between March 2004
and June 2004.


    As an additional incentive to participate in the convertible note financing,
shareholders of series A, B, C, D, E, F and G preferred shares participating in
the convertible note financing at a minimum level based on their respective
ownership percentage were entitled to exchange their original preferred shares
for A-1, B-1, C-1, D-1, E-1, F-1 and G-1 preferred shares, respectively, whose
terms were identical to the original preferred shares, except that the new
preferred shares would be preferential in liquidation to all original preferred
shares.


    The convertible note and warrant agreement provided for the automatic
conversion of the outstanding principal balance and accrued interest upon the
closing of our next equity financing which raised at least $10,000,000 in gross
proceeds. As a result of the financing that closed on September 10, 1999, the
notes and aggregate accrued interest of $414,946 converted, according to the
terms of the agreement, into 1,872,362 Series H1 preferred shares and we granted
the investors additional warrants to purchase 253,874 common shares at a
purchase price of $1.00 per share. Each investor was issued the number of
Series H1 preferred shares calculated by dividing the sum of each investor's
note and accrued interest by $7.00 and a warrant to purchase 0.02 common shares
at $1.00 per share for each $1.00 of principal note amount. These warrants
expire on September 10, 2002 or upon the consummation of an initial public
offering. The liquidation preference for all Series H1 preferred


                                       69
<PAGE>

shares issued in the equity financing and the subsequent conversion of notes was
$7.00 per share. Additional information regarding the Series H1 preferred share
financing is provided below.


    The following table shows officers, directors, 5% shareholders and
affiliated investors who participated in our convertible note and warrant
financing.

Intasys Corporation's common shares at an exercise price of $3.31 per share.
This second warrant issued to Intasys Corporation also expires on the earlier of
three years from the issuance date or upon the effectiveness of an initial

to a warrant to purchase 100,000 common shares at $1.00 per share issued to
Intasys Corporation in the sale of the Series H1 preferred shares.


CONVERSION OF PRINCIPAL UNDER CONVERTIBLE NOTE AND WARRANT FINANCING


    The sale of Series H1 preferred shares to Intasys Corporation and MediaTel
Capital met the minimum financing requirements and triggered the automatic
conversion provided in the convertible note and warrant agreement. In
September 1999 the notes, along with accrued interest, converted into 1,872,362
Series H1 preferred shares and warrants to purchase 253,874 common shares at an
exercise price of $1.00 per share.


TERMS OF SERIES H1 PREFERRED SHARES

    The Series H1 preferred shares contain a $7.00 per share liquidation
preference and converts to common shares on a one-to-one basis. Concurrently
with the sale of the Series H1 preferred shares, Intasys Corporation, MediaTel
Capital and the investors in the convertible note and warrant financing entered
into a registration rights agreement with us providing the registration rights
described in "Description of Share Capital--Registration Rights".

    Intasys Corporation and MediaTel Capital also entered into a voting
agreement with us providing for the election of our board of directors.
Additional information regarding the voting agreement is provided below.

SERIES I1 PREFERRED SHARE FINANCING

    In November and December 1999 we sold 1,526,663 Series I1 preferred shares
to Alcatel and 2,000,000 Series I1 preferred shares to Holodeck Limited at $8.00
per share for a total of $28,213,304. We incurred financing costs of $200,000 in
connection with this financing.

PURCHASE AND DISTRIBUTION AGREEMENT

    Concurrently with the sale of Series I1 preferred shares, Alcatel entered
into an agreement with us in which Alcatel agreed to purchase goods and services
according to certain specifications and we agree to supply the goods and
services.


    This agreement establishes minimum amounts of goods and services to be
purchased by Alcatel in each successive six month period, beginning with the six
month period starting January 1, 2000. If the established minimum amount of
goods for each six month period is not purchased, Alcatel shall pay us a
percentage of the shortfall of goods not purchased for that six months. If
Alcatel exceeds its commitment for a six month period, we shall credit Alcatel a
percentage of the exceeded amount. The agreement requires that we meet certain
product development objectives by various milestone dates. Among other
objectives, we must conduct the beta test by May 15, 2000 and have Alcatel's
final acceptance by July 15, 2000. The agreement terminates on December 31,
2001, but is automatically renewable for successive twelve month periods.


    If Ericsson, Lucent Technologies, Siemens, Cisco or Nokia purchases more
than 15% of our shares, the terms of this agreement with Alcatel will be
modified to allow Alcatel, at its election, to extend the duration of this
agreement or to terminate this agreement with a six month prior written notice
and Alcatel's minimum purchase requirements will be terminated. If Ericsson,
Lucent Technologies, Siemens, Cisco or Nokia purchases more than 50% of our
shares, we change our business model or fail to meet the terms of this
agreement, the terms of this agreement with Alcatel will be modified as

                                       72
<PAGE>
described in the preceding sentence and Alcatel may elect to receive a
manufacturing license from us for a fee.

    This agreement between us and Alcatel may be immediately terminated, in
whole or in part, by either party if the other party fails to remedy a breach of
the agreement within 90 days of a written request, declares or seeks bankruptcy
protection or ceases to carry on business.


PURCHASE AGREEMENT



    Concurrently with the sale of Series I1 preferred shares, an affiliate of
Hutchison entered into an agreement with us in which the affiliate agreed to
purchase goods and services in Sri Lanka according to certain specifications and
we agree to supply the goods and services.



    In connection with this agreement, we entered into an exclusivity agreement
in which we agreed not to sell our WAVEXchange and WAVExpress products to any
party in Sri Lanka other than Hutchison's affiliate for a period of three years.
This period will be extended two years if at the end of the three year period
Hutchison's affiliate has ordered equipment in the aggregate value of
$15 million. In this agreement, we also agreed not to sell these products to any
party in Mumbai, India until March 31, 2000. If by that date Hutchison or its
affiliate has placed an order for the products in the aggregate value of
$6 million, we will not supply these products to any third party for three
years. This period will be extended two years if at the end of the three year
period Hutchison or its affiliate has placed an order in an aggregate value of
$15 million.



    This agreement between us and the affiliate of Hutchison may be immediately
terminated by this affiliate if we fail to complete the work under the agreement
and the failure continues for 45 days after written notice is sent by the
affiliate to us.


TERMS OF SERIES I1 PREFERRED SHARES

    The Series I1 preferred shares contain a $8.00 per share liquidation
preference and convert to common shares on a one-to-one basis. Concurrently with

described in "Description of Share Capital--Registration Rights".

    Alcatel and Holodeck Limited also entered into a voting agreement with us
providing for the election of our board of directors. Additional information
regarding the voting agreement is provided below.

LOAN TO DR. LU

expiring option holdings. The options were exercised for 400,000 of our common
shares at an exercise price of $0.33 per share. In exchange for the loan,
Dr. Lu entered into a promissory note with us in which she agreed to repay the

directors and executive officers. Our non-employee directors will also be
eligible for option grants under our 1999 option plan. Please see "Management"
for information regarding these matters.

FUTURE TRANSACTIONS

    We believe that the transactions described in this section were made on
terms no less favorable than could have been obtained from third parties. We
plan to adopt a policy that requires all future transactions between us and
officers, directors and affiliates to be on terms no less favorable than could
be obtained from unaffiliated third parties and such future transactions must be
approved by a certain number or percentage of disinterested directors. Under our
bye-laws, our directors may participate in transactions involving us or in which
we are interested.

                          DESCRIPTION OF SHARE CAPITAL

GENERAL


    After this offering, we will be authorized to issue 100,000,000 common
shares, $0.001 par value, and 10,000,000 shares of undesignated preferred
shares, $0.001 par value. Immediately after this offering, we estimate there
will be approximately 43,870,878 common shares outstanding, 7,286,594 common
shares will be issuable upon exercise of outstanding warrants, 5,317,191 common
shares issuable on exercise of outstanding options and no preferred shares will
be issued and outstanding as of January 18, 2000. The weighted average exercise
price of the options is $1.56 and the weighted average exercise price of the
warrants is $0.75.


    Our memorandum of association and bye-laws contain provisions that are
intended to enhance the likelihood of continuity and stability in the
composition of the board of directors and which may have the effect of delaying,
deferring, or preventing a future takeover of us unless such takeover or change
in control is approved by the board of directors.

COMMON SHARES

    Holders of common shares are entitled to one vote per share on all matters
to be voted upon by the shareholders.

    Holders of the common shares are entitled to receive such dividends as may
be declared from time to time by the board of directors out of funds legally
available therefor, subject to the terms of any existing or future agreements
with holders of our preferred shares. We have never declared or paid cash
dividends on our capital shares, expect to retain future earnings, if any, for
use in the operation and expansion of our business, and do not anticipate paying
any cash dividends in the foreseeable future. In the event of our liquidation,
dissolution or winding up, the holders of common shares are entitled to share
ratable in all assets legally available for distribution after payment of all
debts and other liabilities and subject to the prior rights of any holders of
preferred shares then outstanding. Holders of common shares have no preemptive
or other subscription or conversion rights. There are no redemption or sinking
fund provisions applicable to the common shares.

PREFERRED SHARES

    Effective upon the closing of this offering, we will be authorized to issue
10,000,000 shares of undesignated preferred shares, none of which will be
outstanding. The board of directors has the authority to issue the preferred
shares in one or more series and to fix the price, rights, preferences,
privileges and restrictions thereof, including dividend rights, dividend rates,
conversion rights, voting rights, terms of redemption, redemption prices,
liquidation preferences and the number of shares constituting a series or the
designation of such series, without any further vote or action by our
shareholders. The issuance of preferred shares, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, could have the effect of delaying, deferring or preventing a change in
control of us without further action by the shareholders and may adversely
affect the market price of, and the voting and other rights of, the holders of
common shares. The issuance of preferred shares with voting and conversion
rights may adversely affect the voting power of the holders of common shares,
including the loss of voting control to others. We have no current plans to
issue any preferred shares. The conversion rate of the existing preferred shares
to common shares is 1:1. All outstanding shares will convert to common shares
upon the closing of this offering.

REGISTRATION RIGHTS


    Certain shareholders holding an aggregate of 27,566,806 shares are entitled
to rights with respect to registration of these shares under the securities act.
The rights are provided under the terms of an


                                       79
<PAGE>

agreement between us and the holders of registrable securities. Beginning six
months following the completion of this offering, holders of then outstanding
registrable securities may require on up to two occasions and Nortel Networks
may require on one occasion that we register their shares for public resale. We
are obligated to register these shares only if the outstanding registrable
securities have an anticipated public offering price of at least $5,000,000.
Also, holders of registrable securities who hold more than one percent of our
outstanding registerable securities may require, on one separate occasion in any
12 month period and four occasions in the aggregate, that shares for public
resale on Form F-3 or similar short-form registration if the value of the
securities to be registered is at least $1,000,000. Furthermore, in the event we
determine to register any of our securities under the Securities Act of 1933,
either for our own account or for the account of other security holders
exercising their registration rights, the holders of registrable securities are
entitled to include their common shares in the registration. The registration
rights are subject to conditions and limitations, among them our right to limit
the number of shares included in the registration which may reduce the number of
shares proposed to be registered in view of market conditions. These
registration rights are not triggered by this offering. All expenses in
connection with any registration, other than underwriting discounts and
commissions, will be borne by us. All registration rights will terminate five
years following the consummation of this offering.


ANTITAKEOVER EFFECTS OF SOME PROVISIONS OF MEMORANDUM OF ASSOCIATION AND
  BYE-LAWS

    The following provisions, summarized below, are generally expected to
discourage coercive takeover practices and inadequate takeover bids. These
provisions are also designed to encourage persons seeking to acquire control of
us to first negotiate with our board. We believe that the benefits of increased
protection resulting from our potential ability to negotiate with the proponent
of an unfriendly or unsolicited proposal to acquire or restructure us outweigh
the disadvantage of discouraging these proposals because we believe that the
negotiation of these proposals could result in an improvement of their terms.

ELECTION AND REMOVAL OF DIRECTORS

    Our board of directors is divided into three classes. The directors in each
class will serve for a three-year term, one class being elected each year by our
shareholders. This system of electing and removing directors may tend to
discourage a third party from making a tender offer or otherwise attempting to
obtain control of us because it generally makes it more difficult for
shareholders to replace a majority of the directors.

SHAREHOLDER MEETINGS

    Under our bye-laws, only the board of directors, the chairman of the board,
the president and any shareholder or group of shareholders holding greater than
10% of the voting shares may call special meetings of shareholders. Under
Bermuda law, shareholders may act by written consent only if the written consent
is unanimous.

REQUIREMENTS FOR ADVANCE NOTIFICATION OF SHAREHOLDER NOMINATIONS AND PROPOSALS

    Our bye-laws establish advance notice procedures with respect to shareholder
proposals and the nomination of candidates for election as directors, other than
nominations made by or at the direction of the board of directors or a committee
of the board. A minimum of 120 calendar days written notice is required. The
notice shall specify the place, day and time of the meeting, and the general
nature of the business to be considered. No business not referred to in the
notice shall be conducted at such meeting.

                                       80
<PAGE>
UNDESIGNATED PREFERRED SHARES

    The authorization of undesignated preferred shares makes it possible for the
board of directors to issue preferred shares with voting or other rights or
preferences that could impede the success of any attempt to change control of
us. These and other provisions may have the effect of deferring hostile
takeovers or delaying changes in control of us or our management.

AMENDMENT OF BYE-LAWS PROVISIONS

    The amendment of the above provisions relating to the election and removal
of directors, shareholder meetings and elimination of shareholder action by
written consent requires approval by holders of at least 66% of the outstanding
common shares.

NASDAQ NATIONAL MARKET LISTING

    We have been approved, subject to notice of issuance, for listing our shares
on the Nasdaq Stock Market's National Market under the symbol "IWAV."

TRANSFER AGENT

    The transfer agent and registrar for the common shares is Norwest Bank
Minnesota, N.A. Norwest's telephone number for shareholder inquiries is
(800) 468-9716.

                       CERTAIN BERMUDA LAW CONSIDERATIONS

    The following discussion is based on the advice of Conyers Dill & Pearman,
our Bermuda counsel. We have been designated as a non-resident for exchange
control purposes by the Bermuda Monetary Authority, Foreign Exchange Control,
whose permission for the issue and transfer of common shares has been obtained
subject to the common shares being listed on the Nasdaq National Market. This
Prospectus has been filed with the Registrar of Companies in Bermuda in
accordance with Bermuda law.

    The transfer of common shares between persons regarded as non-resident in
Bermuda for exchange control purposes and the issue of shares after the
completion of the offering to such persons may be effected without specific
consent under the Exchange Control Act, 1972 and regulations thereunder subject
to the common shares being listed on the Nasdaq National Market. Issues and
transfers of shares to any person regarded as resident in Bermuda for exchange
control purposes require specific prior approval under the Exchange Control Act,
1972.

    There are no limitations on the rights of persons regarded as non-residents
of Bermuda for foreign exchange control purposes owning common shares to hold or
vote their common shares. Because we have been designated as a non-resident for
Bermuda exchange control purposes, there are no restrictions on our ability to
transfer funds in and out of Bermuda or to pay dividends to United States
residents or other non-residents of Bermuda who are holders of common shares,
other than in respect of local Bermuda currency. In addition, because we have
been designated as a non-resident for Bermuda exchange control purposes, we do
not intend to maintain Bermuda dollar deposits and, accordingly, will not pay
dividends on the common shares in Bermuda currency.

    In accordance with Bermuda law, share certificates are issued only in the
names of corporations or individuals. In the case of an applicant acting in a
special capacity (for example, as an executor or trustee), certificates may, at
the request of the applicant, record the capacity in which the applicant is
acting. Notwithstanding the recording of any such special capacity, we are not
bound to investigate or incur any responsibility in respect of the proper
administration of any such estate or trust. We will take no notice of any trust
applicable to any of its common shares whether or not we had notice of the
trust.

    There is no minimum subscription which must be raised by this offering to
provide the sums required to be provided for under Section 28 of the Companies
Act 1981 of Bermuda.

<PAGE>
                                    TAXATION

    We believe that a significant portion of our income will be earned in
Bermuda, which currently has no corporate income tax, or other countries with
favorable tax regimes such as Hong Kong and the Netherlands in which we or our
affiliates conduct activities or in which our customers are located. However,
this belief is based upon the anticipated nature and conduct of our business,
which may change, and upon our understanding of our position under the tax laws
of the various countries in which we have assets or conduct activities, which
position is subject to review and possible challenge by taxing authorities and
to possible changes in law which may have retroactive effect. The extent to
which certain taxing jurisdictions, including the United States, may require us
to pay tax or to make payments in lieu of tax cannot be determined in advance.
In addition, our operations and the payments due to us may be affected by
changes in taxation, including retroactive tax claims or assessments of
withholding on amounts payable to us or other taxes assessed at the source, in
excess of the taxation anticipated by us based on business contacts and
practices of ours and the current tax regimes. There can be no assurance that
these factors will not have a material adverse effect on us.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    We and our non-United States subsidiaries will be subject to United States
federal income tax at regular corporate rates, as well as branch profits tax, on
our income that is effectively connected with the conduct of a trade or business
within the United States, and will be required to file federal income tax
returns reflecting that income. We intend to conduct our operations so as to
reduce the amount of our effectively connected income. However, no assurance can
be given that the Internal Revenue Service will agree with the positions taken
by us in this regard. Moreover, our United States subsidiary will be subject to
United States federal income tax on its worldwide income regardless of its
source, subject to reduction by allowable foreign tax credits, and distributions
by the United States subsidiary to us will be subject to United States
withholding.

BERMUDA TAX CONSIDERATIONS

    Under current Bermuda law, we are not subject to tax on income or capital
gains. Furthermore, we obtained from the Minister of Finance of Bermuda under
the Exempted Undertakings Tax Protection Act 1966, an undertaking that, in the
event that Bermuda enacts any legislation imposing tax computed on profits,
income, any capital asset, gain or appreciation, or any tax in the nature of
estate duty or inheritance tax, then the imposition of the tax will not be
applicable to us or to any of our operations, or to our capital, or to our
capital shares, until March 28, 2016. This undertaking does not, however,
prevent the imposition of property taxes on any of our real property or
leasehold interests in Bermuda.

    We are required to pay to the Bermuda government an annual registration fee
based upon our assessable capital subject to a maximum fee of BD$26,500.

TAXATION OF SHAREHOLDERS

BERMUDA TAX CONSIDERATIONS

    Under current Bermuda law, no income, withholding or other taxes or stamp or
other duties are imposed upon the issue, transfer or sale of capital shares or
on any payments thereunder. See "Taxation--Bermuda Tax Considerations" for a
description of the undertaking on taxes obtained by us from the Minister of
Finance of Bermuda.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

    The following is a summary of certain United States federal income tax
considerations that apply to the acquisition, ownership and disposition of our
common shares by United States shareholders as of the date hereof.

    Although the following summary does not purport to describe all of the tax
considerations that may be relevant to a prospective purchaser of our common
shares, this summary describes the material United States federal income tax
consequences to a United States shareholder. No assurance can be given that the
conclusions set out below would be sustained by a court if challenged by the
Internal Revenue Service. This summary deals only with common shares that are
held as capital assets by United States shareholders, and does not address tax
considerations applicable to United States shareholders that may be subject to
special tax rules, such as dealers or traders in securities, financial
institutions, insurance companies, tax-exempt entities, United States
shareholders that hold common shares as a part of a straddle, conversion
transaction, constructive sale or other arrangement involving more than one
position, United States shareholders that owned or are deemed to own 10% or more
of the total combined voting power of all classes of our voting shares, United
States shareholders that have a principal place of business or "tax home"
outside the United States or United States shareholders whose functional
currency is not the United States dollar. Further this summary does not address
the alternative minimum tax consequences of an investment in our common shares.

    The discussion below is based upon the provisions of the Internal Revenue
Code and regulations, rulings and judicial decisions thereunder as of the date
hereof; any such authority may be repealed, revoked or modified, perhaps with
retroactive effect, so as to result in federal income tax consequences different
from those discussed below.

    The discussion set out below is intended only as a summary of certain United
States federal income tax consequences of an investment in common shares.
Prospective investors are urged to consult their own tax advisors as to the tax
consequences of an investment in the common shares, including the application to
their particular situation of the tax considerations discussed below, as well as
the application of state, local or foreign tax laws. The statements of United
States federal income tax law set out below are based on the laws in force and
interpretations thereof as of the date of this prospectus, and are subject to
any changes occurring after that date.

    A United States shareholder of common shares means a holder that is:

    - a citizen or resident of the United States;

    - a corporation, partnership or other entity created or organized in or
      under the laws of the United States or any political subdivision thereof;
      or

    - an estate or trust the income of which is subject to United States federal
      income taxation regardless of its source.

    TAXATION OF DIVIDENDS.  Distributions received from us by United States
shareholders will constitute dividends for U.S. federal income tax purposes and
will be taxable in the United States as ordinary income to the extent of our
current or accumulated earnings and profits. Amounts paid as dividends that
exceed our current or accumulated earnings and profits will be treated first as
a non-taxable return of capital that reduces the United States shareholder's tax
basis in the common shares, and any amount in excess of the shareholder's U.S.
tax basis will be treated as either long-term or short-term capital gain,
depending on the shareholder's holding period for the common shares. Dividends
paid by us are not eligible for the dividends received deduction otherwise
allowed to United States shareholders on dividends from U.S. corporations.

    TAXATION OF CAPITAL GAINS.  A United States shareholder will recognize gain
or loss for U.S. federal income tax purposes upon the sale, exchange or other
disposition of common shares in an amount

                                       83
<PAGE>
equal to the difference between the amount realized from the sale, exchange or
other disposition and the shareholder's tax basis in the common shares. In most
cases, the gain or loss will be capital gain or loss, and will be long-term
capital gain or loss if such shareholder's holding period for the common shares
is more than one year. The deductibility of capital losses is restricted and may
only be used to reduce capital gains, except that individual taxpayers may
deduct annually $3,000 of capital loss in excess of their capital gains.

    U.S. INFORMATION REPORTING AND BACKUP WITHHOLDING.  Distributions made by us
with respect to our common shares and gross proceeds received from the
disposition of the common shares may be subject to certain information reporting
requirements to the Internal Revenue Service and to a 31% backup withholding
tax. However, backup withholding generally will not apply to payments made to a
United States shareholder who furnishes a correct taxpayer identification number
and provides certain other required information. If backup withholding applies,
the amount withheld is not an additional tax, but is credited against the
shareholder's United States federal income tax liability.

    PASSIVE FOREIGN INVESTMENT COMPANIES.  We will be classified as a passive
foreign investment company for United States federal income tax purposes if we
satisfy either of the following two tests:

    - 75% or more of our gross income is passive income; or

    - on average for the taxable year, 50% or more of our assets by value or by
      adjusted basis produce or are held for the production of passive income.

    We do not believe that we satisfy or, after the completion of this offering,
will satisfy either of the tests for passive foreign investment company status.
Because the determination of whether the common shares constitutes shares of a
passive foreign investment company will be based upon the composition of our
income and assets from time to time, there can be no assurance that we will not
be considered a passive foreign investment company for any future fiscal year.
If we are a passive foreign investment company for any taxable year, U.S.
holders would be required to either:

    - pay an interest charge together with tax calculated at maximum ordinary
      income rates on certain "excess distributions"; or

    - if a qualified electing fund election is made, to include in their taxable
      income certain undistributed amounts of our income.

    Each U.S. holder should consult its own tax advisor regarding the
advisability of making the qualified electing fund election.

                        SHARES ELIGIBLE FOR FUTURE SALE

    We cannot provide any assurance that after this offering has been completed
a significant public market for our common shares will develop or be sustained.
The sale of substantial numbers of our common shares in the public market, or
the possibility of a sale, could adversely affect prevailing market prices for
our common shares. Furthermore, only a limited number of our common shares
currently held by our shareholders will be available for sale shortly after this
offering because of contractual and legal restrictions on resale described
below. Future sales of substantial amounts of our shares in the public market
after these restrictions lapse could adversely affect the prevailing market
price and our ability to raise equity capital in the future.


    Upon completion of this offering and assuming no exercise after that date of
the underwriters' over-allotment option or of any outstanding options or
warrants, we expect to have 43,870,878 common shares outstanding based on shares
outstanding as of January 18, 2000.



    Of the common shares, 8,000,000 of the shares that we expect to sell in the
offering, and any common shares sold upon exercise of the underwriters'
over-allotment option, will be freely tradable without restriction under the
securities act. However, there will be trading restrictions imposed on
"affiliates" and "control persons" as defined under Rule 144. The remaining
common shares held by existing shareholders are restricted securities as that
term is defined in Rule 144 of the securities act. Restricted securities may be
sold in the public market only if registered or if they qualify for an exemption
from registration under Rule 144 promulgated under the securities act, which
rules are summarized below. As a result of the contractual restrictions
described below and the provisions of Rule 144, the restricted securities will
be eligible for sale in the public market immediately following the offering
subject to the expiration of 180-day lock-up agreements with representatives of
the underwriters and to volume limitations and other conditions under Rule 144.
Following this offering, the holders of an aggregate of 27,566,806 of the
outstanding common shares and 7,286,594 common shares issuable upon the exercise
of warrants have the right to require us to register their shares for sale upon
meeting requirements to which the parties have previously agreed. See
"Description of Share Capital--Registration Rights" for additional information
regarding registration rights.



    The following table indicates approximately when the 43,157,472 of our
common shares, held by existing shareholders, that are not being sold in the
offering but which will be outstanding at the time the offering is complete will
be eligible for sale into the public market:

2000 and assumes conversion of all outstanding preferred shares into common
shares and the exercise of the 9,286,594 warrants outstanding as of January 18,
2000.


LOCK-UP AGREEMENTS

    Our officers and directors and substantially all our existing shareholders
have signed lock-up agreements under which they agreed not to dispose of or
hedge any common shares or securities convertible into or exchangeable for
common shares for a period of 180 days from the date of this prospectus.
Dispositions can be made sooner with the prior written consent of Salomon Smith
Barney Inc.

                                       85

OPTIONS AND WARRANTS


    As of January 18, 2000, a further 1,818,867 and 300,000 of the common shares
will be reserved for future issuance pursuant to our 1999 option plan and 1999
employee share purchase plan, respectively. An aggregate of 1,727,697 common
shares issuable upon the exercise of the outstanding options will be vested
180 days following the date of this prospectus. At the date of the offering, a
total of 1,248,813 shares issuable on the exercise of options held by employees
shall be vested and exercisable and not subject to the lock-up agreements. We
intend to file, shortly after to effectiveness of this offering, a registration
statement on Form F-3 or F-8 under the securities act covering all common shares
reserved for issuance under the share plans and subject to outstanding options
under our 1994 stock plan. Substantially all of the common shares issuable upon
exercise of outstanding options are subject to 180-day lock-up agreements with
the representatives of the underwriters.


    At the date of the offering, none of the shares issuable on exercise of
outstanding warrants will be eligible for sale. After 180 days following the
date of the prospectus upon the expiration of the lock-up agreements, 9,478,805
of the common shares issuable on exercise of the outstanding warrants will first
become available for sale in the public markets. The warrants expire prior to
March 3, 2004.


    Outstanding warrants to purchase 2,000,000 preferred shares and 1,132,874
common shares will expire on the closing of the offering if not exercised
earlier. We have received commitments from the preferred warrant holder and
holders of warrants to purchase 188,410 common shares that they intend to
exercise their warrants. The exercise price of these warrants is less than the
minimum estimated initial public offering price per share.


RULE 144

    In general, under Rule 144, as in effect on the date of this prospectus, any
person who has beneficially owned restricted securities for at least one year
will be entitled to sell in any three-month period a number of shares that does
not exceed the greater of:


    - 1% of the then outstanding common shares which are approximately 430,000
      shares immediately after the offering; or


    - the average weekly trading volume of our common shares on the Nasdaq
      National Market during the four calendar weeks immediately preceding the
      date on which notice of the sale is filed with the SEC. Sales of
      restricted securities pursuant to Rule 144 are subject to certain
      requirements relating to manner of sale, notice and availability of
      current public information about us. Our affiliates must also comply with
      the restrictions and requirements of Rule 144, other than the one-year
      holding period requirement, in order to sell common shares which are not
      restricted securities.

RULE 144(K)

    Under Rule 144(k), a person who is not deemed to have been one of our
"affiliates" 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,
generally including the holding period of any prior owner other than an
"affiliate," is entitled to sell those shares without complying with the manner
of sale, notice filing, volume limitation or notice provisions of Rule 144.
Therefore, unless otherwise restricted, "144(k) shares" may be sold immediately
upon the completion of this offering.

RULE 701

    Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 may be relied upon with respect to
the resale of securities originally purchased from us by employees, directors,
officers, consultants or advisers between May 20, 1988, the effective date of

                                       86
<PAGE>
Rule 701, and the date the issuer becomes subject to the reporting requirements
of the securities exchange act, pursuant to written compensatory benefit plans
or written contracts relating to the compensation of such persons. In addition,
the SEC has indicated that Rule 701 will apply to typical stock options granted
by an issuer before it becomes subject to the reporting requirements of the
exchange act, along with the shares acquired upon exercise of such options
beginning May 20, 1988. Securities issued in reliance on Rule 701 are restricted
securities and, subject to the contractual restrictions described above,
beginning 90 days after the date of this prospectus, such securities may be
sold:

    - by persons other than our affiliates, subject only to the manner of sale
      provisions of Rule 144; and

    - by our affiliates under Rule 144 without compliance with its one-year
      minimum holding period requirements.

</TABLE>

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

    The underwriters, for whom Salomon Smith Barney Inc., Banc of America
Securities LLC and SG Cowen Securities Corporation are acting as
representatives, initially propose to offer some of the common shares directly
to the public at the public offering price set forth on the cover page of this
prospectus and some of the common shares to various securities dealers at the
public offering price less a concession not exceeding $      per common share.
The underwriters may allow, and these dealers may reallow, a concession not
exceeding $      per common share to certain brokers and dealers. After the
initial offering of the common shares to the public, the public offering price
and other selling terms may from time to time be varied by the representatives.
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 an option, exercisable for 30 days after
the date of this prospectus, to purchase up to an aggregate of 1,200,000
additional common shares at the public offering price less the underwriting
discount. The underwriters may exercise this option solely to cover
over-allotments, if any, in connection with this offering. To the extent that
the underwriters exercise this option, each of them will be obligated, subject
to certain conditions, to purchase a number of additional shares approximately
proportionate to the underwriters' initial commitment.

    interWAVE, each of our officers and directors and our other shareholders
have agreed with the representatives that, for a period of 180 days after the
date of this prospectus, they will not, without the prior written consent of
Salomon Smith Barney Inc., dispose of or hedge any common shares or any of our
securities convertible into or exchangeable for common shares other than, in the
case of interWAVE, shares pursuant to any employee stock option plan, stock
ownership plan or dividend reinvestment plan of interWAVE in effect at the time
the underwriting agreement is signed and common stock issuable upon the
conversion of securities or the exercise of warrants outstanding at the time the
underwriting agreement is signed, and in the case of the officers, directors and
shareholders, shares of common stock disposed of as bona fide gifts approved by
Salomon Smith Barney Inc. Salomon Smith Barney Inc. in its sole discretion may
release any of the securities subject to the lock-up agreements at any time
without notice. The release of any lock-up is considered on a case by case
basis. Factors in deciding whether to release shares may include the length of
time before the lock-up expires, the trading price of the common stock and
whether the person seeking the release is an officer,

                                       88

director or affiliate of interWAVE. Salomon Smith Barney Inc. has no current
intention to release shares subject to the lock-up agreements.


    The underwriters have reserved for sale, at the initial public offering
price, up to 1,300,000 common shares for customers, directors, employees and
other persons associated with us who have expressed an interest in purchasing
common shares in the offering. This group may include Alcatel which may purchase
approximately 600,000 common shares and entities associated with the principal
stockholder of Hutchison Whampoa Limited, which is the corporate parent of
Holodeck Limited, one of our shareholders which may purchase approximately
500,000 common shares. 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 the common
shares. Consequently, the initial public offering price for the common shares
was determined by negotiations between 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. We cannot assure you, however,
that the prices at which the 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 the common shares will develop
and continue after the offering.

    We have applied to have our common shares included for quotation on the
Nasdaq Stock Market's National Market under the symbol "IWAV."

    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 common shares.

    In connection with the offering, Salomon Smith Barney Inc. on behalf of the
underwriters, may over-allot, or engage in syndicate covering transactions,
stabilizing transactions and penalty bids. Over-allotment involves syndicate
sales of common shares 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 shares 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 shares made for the purpose of preventing or retarding a
decline in the market price of the common shares while the offering is in
progress. 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. These activities may cause the price of the
common shares 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.

    The prospectus may be used by underwriters and dealers in connection with
offers and sales of the common shares, including common shares initially sold
outside the United States, to persons located in the United States.

    We have agreed to indemnify the several underwriters against certain
liabilities, including liabilities under the securities act, or to contribute to
payments the underwriters may be required to make with respect to any of those
liabilities.

    Initial sales of the common shares offered in the United States will be
settled in U.S. dollars. Subsequent trading of common shares effected on the
Nasdaq National Market will be settled in U.S. dollars in accordance with the
normal settlement practices of the Nasdaq.

                                 LEGAL MATTERS

Bermuda law relating to the offering are being passed upon for us by Conyers

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
interWAVE Communications International, Ltd.:

    We have audited the accompanying consolidated balance sheets of interWAVE
Communications International, Ltd. and subsidiaries as of June 30, 1999 and
1998, and the related consolidated statements of operations, stockholders'
equity and comprehensive loss, and cash flows for each of the years in the three
year period ended June 30, 1999. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of interWAVE
Communications International, Ltd. and subsidiaries as of June 30, 1999 and
1998, and the results of their operations and their cash flows for each of the
years in the three year period ended June 30, 1999 in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                FISCAL YEARS ENDED JUNE 30, 1997, 1998 AND 1999

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (A) DESCRIPTION OF BUSINESS

    interWAVE Communications International, Ltd. (the Company) develops,
manufactures and markets compact mobile wireless network solutions for GSM
wireless communications on a global basis. The Company's products are primarily
marketed to communication equipment providers, wireless service providers and
systems integrators.

    The Company has a fiscal year that ends on the Friday nearest June 30.
Fiscal 1997 and 1998 were 52 week years. Fiscal 1999 was a 53 week year. For
presentation purposes the accompanying consolidated financial statements and
notes refer to the calendar month-end.

    Effective November 1, 1997, the Company sold the assets and liabilities of
its offices in the United Kingdom and China to ADC Telecommunications, Inc. for
$1,016,806 which was substantially equal to the net book value on the date of
sale. All employees of the offices were transitioned to ADC to assist them with
the marketing, sale and service of interWAVE products through their channels. As
part of the sale, the Company modified its purchase/resale agreement with ADC
Telecommunications.

    (B) BASIS OF ACCOUNTING AND CONSOLIDATION

    The consolidated financial statements of the Company are presented in
conformity with generally accepted accounting principles as adopted in the
United States. The consolidated financial information as of September 30, 1999
and for the three-months ended September 30, 1998 and 1999 is unaudited, but
includes all adjustments (consisting only of normal recurring adjustments) that
the Company considers necessary for the fair presentation of the financial
position at such dates and the operations and cash flows for the periods then
ended. Operating results for the three-months ended September 30, 1999 are not
necessarily indicative of results that may be expected for the entire year.

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries: interWAVE Communications, Inc. (Delaware,
USA); interWAVE Communications B.V. (Netherlands); interWAVE Communications
Solutions Ltd. (United Kingdom); and interWAVE Communications, S.A. (France).
The Company also operates a branch office in Hong Kong. All intercompany
balances and transactions have been eliminated in consolidation.

    (C) INITIAL PUBLIC OFFERING AND UNAUDITED PRO FORMA BALANCE SHEET


    In September 1999, the Board of Directors of the Company authorized the
filing of a registration statement with the Securities and Exchange Commission
(SEC) that would permit the Company to sell shares of the Company's common stock
in connection with a proposed initial public offering (IPO). If the offering is
consummated under the terms presently anticipated, all the then outstanding
shares of the Company's Series A-1, Series B-1, Series C-1, Series D,
Series D-1, Series E, Series E-1, Series F-1, Series G-1, Series H and
Series H-1 convertible preferred stock will automatically convert into shares of
common stock on a one-for-one basis upon the closing of the proposed IPO. In
addition, outstanding warrants to purchase 2,000,000 preferred shares and
1,132,874 common shares, will expire upon the closing of the offering, if not
exercised earlier. The Company has received a firm committment from the
preferred warrant holder that they intend to exercise their warrants.
Additionally, the Company has received firm commitments from certain common
warrant holders that they will exercise their warrants to purchase 188,410
common shares prior to the effectiveness of this

offering. The conversion of all convertible preferred shares, the exercise of
warrants for preferred shares and the exercise of warrants for common shares for
which they have obtained a firm commitment that the warrants will be exercised
have been reflected in the accompanying unaudited pro forma balance sheet as if
it had occurred on September 30, 1999. However, the Company has not reflected
the exercise of the common stock warrants for which the warrant holders have not
yet made a firm commitment. The unaudited pro forma balance sheet also reflects
the issuance of 602,256 common shares upon exercise of options subsequent to
September 30, 1999. Series G1 preferred shares shall not automatically convert
into common shares unless the $25,000,000 aggregate offering price is met and
the price is $7.00 per share or greater.

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    (D) CURRENCY TRANSLATION

    For operations outside of the United States with the local currency as the
functional currency, assets and liabilities are translated at year-end exchange
rates, and statements of operations are translated at the average exchange rates
during the year. Adjustments arising from translation of non-U.S. currency
denominated assets and liabilities for these operations are included as a
component of other comprehensive income in shareholders' equity.

    For non-U.S. operations with the U.S. dollar as the functional currency,
non-U.S. currency denominated assets and liabilities are remeasured into U.S.
dollars using historical rates and any measurement gains and losses are included
in the consolidated results of operations and, to date, have not been
significant.

    (E) CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Investments with an
original maturity of more than three months but less than one year are
classified as short-term investments.

    Cash equivalents and short-term investments are classified as
"available-for-sale" under the provisions of Statement of Financial Accounting
Standards (SFAS) No. 115, ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY
SECURITIES.

    The amortized cost of available-for-sale securities are adjusted for
amortization of premiums and accretion of discounts to maturity. Such
amortization is included in net investment income. As required by SFAS No. 115,
available-for-sale securities are recorded at fair value. Unrealized gains and
losses are reported as a separate component of accumulated other comprehensive
income in stockholders' equity. Realized gains and losses and declines in value
judged to be other than temporary on available-for-sale securities are included
in net investment income. The cost of securities sold is based on the specific
identification method. Interest on securities classified as available-for-sale
are included in other income.

    (F) 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, as a majority of the Company's
customers are large, well established companies.

- ------------------------

        (1) Microcellular Systems, Ltd. was created by a spin-off from ADC
        Telecommunications in May 1999.

    (G) INVENTORIES

    Inventories are stated at the lower of average cost or market.

    (H) PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, less accumulated depreciation,
calculated using the straight-line depreciation method over the estimated useful
lives of the related assets, generally two to five years. Leasehold improvements
are depreciated over the life of the underlying lease or the estimated useful
life, whichever is shorter.

                FISCAL YEARS ENDED JUNE 30, 1997, 1998 AND 1999

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    (I) REVENUE RECOGNITION

    Revenue is recognized when all of the following have occurred: the product
has been shipped, title and risk of loss have passed to the customer (generally
at time of shipment for US shipments and at time of arrival at an international
port for non-US shipments), we have the right to invoice the customer,
collection of the receivable is probable, and we have fulfilled all pre-sale
contractual obligations to the customer. Revenue for installation services is
recognized as the service is performed to the extent of direct installation
costs incurred and the excess is deferred and recognized over the estimated life
of the equipment. Revenue from extended warranty coverage and customer support
is recognized ratably over the period of the service contract. Trial sales made
directly to wireless service providers are not recognized as revenue until the
trial is successfully completed. Trials conducted by communications service
providers and systems integrators are normally shipped from their inventory and
do not result in any incremental revenue to us. Although the Company's products
contain a software component, the software is not sold separately and the
Company is not contractually obligated to provide software upgrades to its
customers.

    The Company provides for estimated warranty costs at the time of sale. Sales
agreements include a 12 to 16 month warranty on all hardware and software.

    (J) RESEARCH AND DEVELOPMENT COSTS

    SFAS No. 86 provides for the capitalization of certain software development
costs once technological feasibility is established subject to an evaluation of
realizability. Capitalized costs are then amortized on a straight-line basis
over the estimated product life or based on the ratio of current revenues to
projected product revenues, whichever is greater. To date, the Company's
products have been available for general release concurrent with the
establishment of technological feasibility; and, accordingly, no development
costs have been capitalized.

    (K) INTANGIBLES

    The Company capitalizes costs of acquiring licenses from third parties for
technologies that have reached technological feasibility and can be incorporated
into the Company's products. The Company also capitalizes certain external costs
associated with patents and trademarks. Except for the license and technical
information agreement discussed in Note 9(a), the Company amortizes these assets
straight line over four years or based on the ratio of current revenues to
projected revenues whichever is greater. Technology licenses generally contain
provisions for royalty payments to licensors based on the number of units sold.

    (L) IMPAIRMENT OF LONG-LIVED ASSETS

    The Company evaluates its long-lived assets, including certain identifiable
intangibles, for impairment whenever events or changes in circumstances indicate
that the carrying amount of such assets might 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 to be recognized is
measured by

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

the amount by which the carrying amount of the asset exceeds the fair value of
the asset. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell.

    (M) INCOME TAXES

    The Company uses the asset and liability method of accounting for income
taxes. Deferred tax assets and liabilities are recognized for the estimated
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates in effect for the year in which those temporary differences
are expected to be recovered or settled. Valuation allowances are established
when necessary to reduce deferred tax assets to the amounts expected to be
realized.

    (N) LOSS PER SHARE

    Basic loss per share is computed using the weighted average number of common
shares outstanding during the period. Diluted loss per share is computed using
the weighted average number of common and dilutive potential common shares
outstanding during the period, using the as-if-converted method for convertible
preferred shares and the treasury stock method for options and warrants. The
effect of including convertible preferred shares, options and warrants would
have been antidilutive during all periods presented. As a result, such effect
has been excluded from the computation of diluted net loss per share during
those antidilutive periods. The total number of shares excluded from diluted net
loss per share relating to these securities was approximately 20,177,168,
1,939,000, and 3,518,201 shares, respectively, for the fiscal year ended 1999.
Pursuant to SEC Staff Accounting Bulletin No. 98, common shares and convertible
preferred shares issued for nominal consideration and options and warrants
granted for nominal consideration prior to the anticipated effective date of the
initial public offering are included in the calculation of basic and diluted net
loss per share, as if they were outstanding for all periods presented. To date,
the Company has not had any issuances of stock, options or warrants for nominal
consideration.

    (O) STOCK-BASED COMPENSATION AND WARRANTS FOR GOODS AND SERVICES

    The Company accounts for stock-based awards to employees using the intrinsic
value method. Expense associated with stock-based compensation is being
amortized on an accelerated basis over the vesting period of the individual
award consistent with the method described in Financial Accounting Standards
Board ("FASB") Interpretation No. 28.

    Warrants issued for goods or services are valued at the fair value of the
equity instrument or the goods or services received, whichever is more readily
determinable. Promises of future services are recorded as contra-equity until
such time as the services are received.

    (P) USE OF ESTIMATES

    The preparation of consolidated 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

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

    (Q) COMPREHENSIVE INCOME

    "Other comprehensive income" refers to revenues, expenses, gains and losses
that are not included in net income, but rather are recorded directly in
stockholders' equity. The only component of other comprehensive income for the
years ended June 30, 1997, 1998 and 1999 was cumulative translation adjustments.

    (R) FAIR VALUE OF FINANCIAL INSTRUMENTS

    The carrying value of cash, cash equivalents, accounts receivable, accounts
payable and accrued expenses, other current liabilities and convertible notes
approximate fair value due to the short maturity of those instruments. The
carrying value of the notes payable approximate fair value due to the variable
interest rates on these notes.

    Cash equivalents and short-term investments have been classified as
available-for-sale securities and consisted of the following (in thousands):

    The net change in the total valuation allowance from the year ended
June 30, 1998, and 1999 was an increase of approximately $6,037,000 and
$4,888,000, respectively. Management believes that sufficient uncertainty exists
regarding the future realization on deferred tax assets, and, accordingly, a
valuation allowance is required.

stock upon the closing of a minimum of $10 million of a new series of preferred
stock to new investors. As a result of the issuance of Series H-1 preferred
shares on September 9, 1999, the notes converted to Series H-1 preferred stock
at a price of $7 per share. As an incentive to participate in the convertible
note financing, current holders of Series A, B, C, D, E, F and G preferred stock
("original preferred stock") who participated at a minimum level based on their
respective ownership percentage were entitled to exchange their original
preferred stock for A-1, B-1, C-1, D-1, E-1, F-1 and G-1 preferred stock,
respectively ("new preferred stock"), whose terms were identical to the original
preferred stock, except that the new preferred stock would be preferential in
liquidation to all original preferred stock. As of June 30, 1999, the
convertible notes, including accrued interest of $231,211, amount to
$12,923,041.


    In conjunction with the bridge loan financing, the participants in the
convertible notes were granted a warrant to purchase one share of common stock
for each $2 invested in the convertible notes. As a result, the Company issued
warrants to purchase 6,345,939 shares of common stock at a price of $0.70 per
share, which are exercisable any time for a period of 5 years from date of
issuance. The proceeds from the bridge financing were allocated between the
convertible notes and the warrants based upon their relative fair values. The
amount of $5,592,552 (net of proportionate value of note receivable of $284,466)
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 6%; expected volatility 70%; and contractual term of 5 years.
The value of the warrants had been recorded as a discount on the convertible
notes payable and additional paid-in-capital and will be amortized over the term
of the debt.


    The note receivable of $527,865 has been recorded as a reduction of the
convertible notes of $243,399 and a reduction of the warrants of $284,466
determined on a basis proportionate to the fair value of the bridge loan and
warrants.

    As of June 30, 1999 no warrants have been exercised. Interest expense of
$1,951,567 has been recorded in connection with the amortization of the discount
in fiscal 1999.

           distributed among the holders of preferred stock are insufficient to
           permit payment of these amounts, then such assets and funds shall be
           distributed to the holders of preferred shares in proportion to the
           respective preferential amounts fixed for each series. Any remaining
           assets shall be distributed among the holders of common shares on a
           pro rata basis. A consolidation or merger of the Company involving
           transfer of more than 50% of the voting power shall be deemed a
           liquidation except in specific circumstances.

    Each holder of preferred shares is entitled to receive, when and if declared
by the Board of Directors, noncumulative dividends at a rate of $0.05 per share.
As of June 30, 1999, no dividends have been declared.

(9) PREFERRED AND COMMON SHARES (CONTINUED)

    Each holder of preferred shares is entitled to one vote per share.

    Each preferred share is convertible into common shares, at the option of the
holder, at any time, on a one-for-one basis subject to adjustment for
antidilution events as defined, and will automatically convert into common
shares in the event of the consummation of an underwritten initial public
offering of not less than $25,000,000. Series G1 preferred shares shall not
automatically convert into common shares unless the $25,000,000 aggregate
offering price is met and the price is $7.00 per share or greater.

    On March 27, 1998 and April 29, 1998, the Company issued an aggregate of
3,714,286 shares of Series G preferred stock and a warrant to purchase 2,000,000
Series G preferred shares at $7.00 per share to Nortel Networks for an aggregate
purchase price of $22,744,000 (net of financing costs of $1,756,000), which
consideration consisted of a $20,000,000 cash payment and licensed technology
valued at $1,000,000, and a technical information agreement valued at
$3,500,000. The amount of $4,629,000 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 3 years. The warrants expire on March 27, 2001
or upon the effectiveness of an initial public offering, whichever is first,
unless previously exercised.

    The licensed technology is being amortized over a five year term. If the
license is terminated in less than five years, the Company will receive a
prorata refund equal to 20% of the amount paid for the license for each
remaining year. The refund may be paid in cash or Series G preferred shares, at
the option of the payor, at their original value. The license technology
agreement is for one year and automatically renews for the duration of the
underlying patents. The technical information agreement provides for the Company
to have access to Nortel Network's technical assistance and testing services and
other documentation and support. The agreement further provides for a refund as
a percentage of the original value as per the following schedule:

<TABLE>
<S>                                                           <C>

March 16, 2002..............................................    15%
March 16, 2003..............................................     0%
</TABLE>

    The Company has recorded this agreement as a contra equity and is amortizing
the value on a basis consistent with their ability to receive a refund.


    On September 10, 1999, the Company completed an offering of 1,715,715 shares
of Series H-1 preferred shares and issued warrants to purchase an aggregate of
240,000 shares of common stock at $1 per share to a group of investors in
exchange for $12,010,000 (before financing costs of $766,000). The Series H-1
contains a $7 per share liquidation preference and converts to common shares on
a one-to-one basis. The warrants valued at $1,340,000 expire three years from
the issuance date, or upon the effectiveness of an initial public offering,
whichever comes first, unless previously exercised. The fair value of the H-1
preferred and common shares at time of issuance of Series H-1 was deemed to be
$7.50 per share, resulting in recognition of a dividend at the time of issuance
(a beneficial conversion) of $2,055,000. The sale of Series H-1 preferred shares
met the minimum $10 million new financing described in footnote 8, and resulted
in the automatic conversion of the convertible notes and interest

accrued thereon into 1,872,362 shares of Series H-1 and the issuance of warrants
to purchase 253,874 shares of common stock for $1 per share to the noteholders.
The warrants expire three years from the issuance date, or upon the
effectiveness of an initial public offering, whichever comes first, unless
previously exercised.


    In September 1999, the Company entered into a memorandum of understanding
expiring in August 2000 with an investor to distribute and manufacture the
investor's products and for the investor to market the company's products in
Canada. The Company expects to enter into a four-year distribution agreement. In
conjunction with the memorandum of understanding the Company issued a warrant to
purchase 615,000 common shares at an exercise price of $1 per share and received
a warrant to purchase 225,225 shares of the investor's publicly traded common
shares at $3.3125 per share expiring in August 2002. The warrant to purchase the
Company's common shares expires on the earlier of September 1, 2002, or the
effectiveness of an initial public offering. The warrant is fully vested,
nonforfeitable and exercisable on the date that the Company and the investor
executed the warrant agreement.

    The amount of $475,650 ascribed to the warrants received by the Company was
estimated using the Black-Scholes option valuation model with the following
assumptions: no expected dividend yield; risk free interest rate of 6%; expected
volatility of 81%; and contractual term of 3 years. The warrant received was
recorded in other assets as of September 30, 1999.


    The amount of $4,120,500 ascribed to the warrants issued to the investor was
estimated using the Black-Scholes option valuation model with the following
assumptions: no expected dividend yield; risk free interest rate of 6%; expected
volatility of 70%; and contractual term of 3 years. The warrant has been
recorded as other paid in capital. The amount of $3,645,500 ascribed to the
services to be received from the investor was determined as the difference in
value between the warrants exchanged. This amount has been recorded as contra
equity and will be amortized to expense over the four year term of the
distribution agreement.


    (B) SHARE OPTION PLAN

    In fiscal 1995, the Board of Directors adopted the 1994 Share Plan (the
Plan) providing for the issuance of common share options to employees and
consultants of the Company. The share options are a combination of both
incentive and non-statutory share options.

    Incentive share options may be granted at not less than 100% of the fair
market value per share, and non-statutory share options may be granted at not
less than 85% of the fair market value per share at the date of grant as
determined by the Board of Directors or committee thereof, except for options
granted to a person owning greater than 10% of the total combined voting power
of all classes of shares of the Company, for which the exercise price must not
be less than 110% of the fair market value. Share option plan shares generally
vest 25% after one year, with the remainder vesting monthly over the following
three years. Additional options granted to existing employees after July 28,
1998 are in general vesting monthly over four years.

    The Company uses the intrinsic value method to account for the 1994 plans.
Accordingly compensation cost has been recognized for its stock options in the
accompanying financial statements if, on the date of grant, the current market
value of the underlying common stock exceeded the exercise price of the stock
options at the date of grant.

(9) PREFERRED AND COMMON SHARES (CONTINUED)

    During fiscal 1997, 1998 and 1999, the Company granted options with a
weighted-average exercise price of $1.07, $1.15 and $0.90 respectively, compared
to the weighted-average fair value of approximately $8.80, $6.37 and $3.03 for
the same respective periods.

    Options generally have 10 year terms. However, options granted to an
optionee who, at the time the option is granted, owns stock representing more
than 10% of the voting power of all classes of stock of the Company, generally
have 5 year terms.

    The Company has reserved 10,730,000 common shares for issuance under the
Plan. A summary of the Company's share option plan activity is as follows:

    Rent expense was approximately $775,000, $822,000, and $960,951 for the
years ended June 30, 1997, 1998, and 1999, respectively.

    (B) CONTRACT MANUFACTURERS

    The Company generally commits to purchase products from its contract
manufacturers to be delivered within the most recent 60 days covered by
forecasts with cancellation fees. As of September 10, 1999, the Company had
committed to make purchases totaling $2.7 million from these manufacturers in
the next 60 days. In addition, in specific instances, the Company may agree to
assume liability for limited quantities of specialized components with lead
times beyond this 60-day period.

(12) LITIGATION

    On June 28, 1999, the Company filed a complaint against JetCell Corporation
in United States District Court alleging misappropriation of trade secrets and
patent infringement. The complaint seeks injunctive relief and damages. On
July 19, 1999, JetCell filed an answer to the complaint and a series of
counterclaims against the Company. The answer denied the allegations made in the
complaint and the counterclaims included allegations against the Company of
unfair trade practices, unfair

competition, defamation, and patent misuse. The answer and counterclaims seek
injunctive relief, damages, invalidation of the Company's patents and a
dismissal of the complaint. The Company is unable to predict the outcome of the
lawsuit and does not expect it to be resolved in the near future. However, if
the Company is unable to settle these proceedings in a satisfactory manner, the
legal proceedings may be time consuming and expensive and the outcome could be
adverse to the Company. If the outcome is adverse to the Company, they would
experience more competition in the Company's markets and may be required to
license technology required for the Company's products, either of which could
harm the Company's business and financial results.

(13) EMPLOYEE BENEFIT PLANS

    The Company maintains a 401(k) defined contribution benefit plan that covers
all U.S. employees who have attained the age of at least 20.5 years. This plan
allows employees to defer up to 20% of their pretax salary in certain
investments at the discretion of the employee. The Company has the option to
make discretionary employer matching contributions. The Company did not make any
matching contributions to the plan during the years ended June 30, 1997, 1998
and 1999.

(14) GEOGRAPHIC SEGMENT INFORMATION

    In fiscal 1999, 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 compact mobile wireless network solutions.

    The following table presents information about the Company by geographic
area: (in thousands)

(15) SUBSEQUENT EVENTS (UNAUDITED)


    In November 1999, the Company completed an offering of 1,526,663 Series I-1
preferred shares to Alcatel in exchange for $12,013,304 (net of financing costs
of $200,000). The Series I-1 contains an $8 per share liquidation preference and
converts to common shares on a one-to-one basis. In connection with the sale of
Series I-1 preferred shares, the Company and Alcatel entered into a purchase and
distribution agreement whereby Alcatel will market the Company's wireless office
network products through their enterprise solutions division.

    In November 1999 the Company received a commitment from a financial
institution for a revolving line of credit in the amount of $5,000,000 for a one
year term subject to advances against eligible accounts receivable.


    The Company has recently signed a lease for approximately 56,000 square feet
in Menlo Park, California for our principal administrative and engineering
facilities. The five-year lease commences December 15, 1999. The Company expects
to sublet the premises in Redwood City following its relocation in early 2000
until the expiration of our Redwood City lease in 2002. Future minimum lease
payments for the new lease are as follows for the fiscal years ending June 30:

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Our Bye-laws provide as follows:

    The Directors, Secretary and other Officers for the time being of the
Company and the liquidator or trustees (if any) for the time being acting in
relation to any of the affairs of the Company and every one of them, and their
heirs, executors and administrators, shall be indemnified and secured harmless
out of the assets of the Company from and against all actions, costs, charges,
losses, damages and expenses which they or any of them, their heirs, executors
or administrators, shall or may incur or sustain by or by reason of any act
done, concurred in or omitted in or about the execution of their duty, or
supposed duty, or in their respective offices or trusts, and none of them shall
be answerable for the acts, receipts, neglects or defaults of the others of them
or for joining in any receipts for the sake of conformity, or for any bankers or
other persons with whom any moneys or effects belonging to the Company shall or
may be lodged or deposited for safe custody, or for insufficiency or deficiency
of any security upon which any moneys of or belonging to the Company shall be
placed out on or invested, or for any other loss, misfortune or damage which may
happen in the execution of their respective offices or trusts, or in relation
thereto, PROVIDED THAT this Indemnity shall not extend to any matter in respect
of any fraud or dishonesty which may attach to any of said persons.

    The Company carries liability insurance which provides for coverage for
officers and directors of the Company and its subsidiaries, subject to certain
deductibles.

    In December 1999, the Registrant will enter into indemnification agreements
with its directors and officers providing for limitations on a director's and
officer's liability for judgments, settlements, penalties, fines, and expenses
of defense (including attorneys' fees, bonds and costs of investigation) arising
out of or in any way related to acts of omissions as a director or an officer,
or in any other capacity in which services are rendered to the Registrant. The
Registrant believes its indemnification agreements will assist it in attracting
and retaining qualified individuals to serve as directors and officers. The
agreements provide that a director or officer is not entitled to indemnification
under such agreements among other cases (i) if the director or officer is not
relieved of liability under applicable law, (ii) for violations of certain
securities laws, or (iii) for certain claims initiated by the officer or
director. In addition, indemnification may not be available to directors or
officers under Bermuda law if any act or omission by a director or officer
amounted to a failure to act honestly and in good faith

                                      II-1
<PAGE>
with a view to the best interests of the Company. Due to the lack of applicable
case law, it is not clear whether indemnification is available in the case of a
breach of securities laws of the United States.

    Insofar as indemnification for liabilities arising under the U.S. Securities
Act may be permitted to directors, officers or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the United States Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

    The following is a summary of transactions by the Company during the last
three years preceding the date hereof involving sales of the Company's
securities that were not registered under the Securities Act:

    - In March 1997, the Registrant sold a total of 1,500,000 Series F preferred
      shares at a price of $11.50 per share to UCOM Company International
      Limited for an aggregate purchase price of $17,250,000 net of financing
      costs of $0. Each Series F preferred share is convertible into one common
      share at the option of the holder, and will automatically convert into
      common shares at the consummation of Registrant's initial public offering.
      These shares were exempt from registration under Rule 506 of the
      Securities Act since the sale was to a corporation, which is defined as an
      accredited investor under Rule 501(a)(3) of the Securities Act.

    - Beginning in March 1998, the Registrant sold a total of 3,714,286
      Series G preferred shares and a warrant to purchase 2,000,000 Series G
      preferred shares at a price of $7.00 per share to Nortel Networks
      Corporation for an aggregate purchase price of $22,744,000 net of
      financing costs of $1,756,000 paid substantially to Goldman
      Sachs & Co., Inc. The consideration consisted of a $20,000,000 cash
      payment and the execution of a license agreement and a technical
      information agreement. The warrant expires on the earlier of March 27,
      2001, the consummation of an initial public offering or a sale of
      substantially all of the assets of the Registrant. Each Series G preferred
      share is convertible into one common share. In April 1999, the Registrant
      granted Nortel Networks Corporation a warrant to purchase 24,000 common
      shares at a purchase price of $1.15 per share. This warrant expires on
      April 22, 2002, upon consummation of an initial public offering or a sale
      of substantially all of the assets of the Registrant. These shares were
      exempt from registration under Rule 506 of the Securities Act since the
      sale was to a corporation, which is defined as an accredited investor
      under Rule 501(a)(3) of the Securities Act.

    - In March 1999, the Registrant entered into a convertible note and warrant
      agreement with 106 investors, all of which were existing shareholders of
      the Registrant. Pursuant to these note financings, the Registrant borrowed
      at 8% annual interest an aggregate amount of $12,691,830 and issued
      warrants to purchase 6,345,931 common shares at a purchase price of $0.70
      per share. These warrants expire on March 3, 2004. On September 10, 1999,
      these notes along with accrued interest converted according to their terms
      into 1,872,335 Series H1 preferred shares, and the Registrant granted the
      investors additional warrants to purchase 253,874 common shares at a
      purchase price of $1.00 per share. These warrants expire on the earlier of
      September 10, 2002, the consummation of an initial public offering or a
      sale of substantially all of the assets of the Registrant. Each Series H1
      preferred share is convertible into one common share. The note financings
      were exempt from registration under Rule 506 of the Securities Act since
      the sale was to 106 accredited investors, as defined and Rule 501 of the
      Securities Act.

    - Beginning in July 1999, the Registrant sold a total of 1,715,715
      Series H1 preferred shares and warrants to purchase 240,000 common shares
      at a price of $7.00 per share to three investors. The warrants expire on
      the earlier of three years from the issuance date or upon the consummation
      of an initial public offering. Each Series H1 preferred share is
      convertible into

                                      II-2

      one common share. The shares were exempt from registration under Rule 506
      of the Securities Act since the sales were to three corporations, which
      are defined as accredited investors under Rule 501(a)(3) of the Securities
      Act.

    - In November and December 1999, the Registrant sold a total of 3,526,663
      Series I1 preferred shares at a price of $8.00 per share to Alcatel USA,
      Inc. and Holodeck Limited for an aggregate purchase price of $28,013,304
      net of financing costs of $200,000. Each Series I1 preferred share is
      convertible into one common share. These shares were exempt from
      registration under Rule 506 of the Securities Act since the sale was to a
      corporation, which is defined as an accredited investor under
      Rule 501(a)(3) of the Securities Act.

ITEM 17.  UNDERTAKINGS

        (a) The Registrant hereby undertakes to provide to the underwriter at
    the closing specified in the underwriting agreements certificates in such
    denominations and registered in such names as required by the underwriter to
    permit prompt delivery to each purchaser.

        (b) Insofar as indemnification for liabilities arising under the
    Securities Act of 1933 (the "Securities Act") may be permitted to directors,
    officers and controlling persons of the Registrant pursuant to the foregoing
    provisions, or otherwise, the Registrant has been advised that in the
    opinion of the Securities and Exchange Commission such indemnification is
    against public policy as expressed in the Securities act and is, therefore,
    unenforceable. In the event that a claim for indemnification against such
    liabilities (other than payment by the Registrant of expenses incurred or
    paid by a director, officer or controlling person of the Registrant in the
    successful defense of any action, suit or proceeding) is asserted by such
    director, officer or controlling person in connection with the securities
    being registered, the Registrant will, unless in the opinion of its counsel
    the matter has been settled by controlling precedent, submit to a court of
    appropriate jurisdiction the question whether such indemnification by it is
    against public policy as expressed in the Securities Act and will be
    governed by the final adjudication of such issue.

        (c) The undersigned Registrant hereby undertakes that:

           (i) 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 the Company 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 at the time it was declared effective; and

           (ii) 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
       the time shall be deemed to be the initial bona fide offering thereof.

             ARTICLE II -- SHARES AND SHAREHOLDERS GENERALLY

or class of shares, any share in the Company may be issued with or have
attached thereto such preferred, deferred, qualified or other special rights
or such restrictions, whether in regard to dividend, voting, return of

shares may, with the sanction of a resolution of the Shareholders, be issued
on terms:

       (a)    that they are to be redeemed on the happening of a specified
event or on a given date and/or,

       (b)    that they are liable to be redeemed at the option of the
Company; and/or

       (c)    if authorized by the Memorandum of the Company, that they are

2.2    SPECIAL RIGHTS

       The special rights conferred upon the holders of any series or class
of shares shall not, unless otherwise expressly provided in the rights
attaching to or the terms of issue of such shares, be deemed to be altered by
the creation or issue of further shares ranking pari passu therewith.

2.3    SHARE ISSUANCES

       Subject to the provisions of these Bye-Laws, the unissued shares of
the Company (whether forming part of the original capital or any increased
capital) shall be at the disposal of the Board, which may offer, allot, grant
options over or otherwise dispose of them to such persons, at such times and
for such consideration and upon such terms and conditions as the Board may
determine.

2.4    BROKERAGE FEES AND COMMISSIONS

       The Board may in connection with the issue of any shares exercise all
powers of paying commission and brokerage conferred or permitted by law.

2.5    SHARE CERTIFICATES

       The preparation, issue and delivery of certificates shall be governed
by the Companies Act.  In the case of a share held jointly by several
persons, delivery of a certificate to one of several joint holders shall be
sufficient delivery to all.

2.6    LOST OR DESTROYED CERTIFICATES

       If a share certificate is defaced, lost or destroyed it may be
replaced without fee, subject to any applicable terms as to evidence and
indemnity and subject to the charge to the Shareholder for the reimbursement
of the reasonable payment of costs and out of pocket expenses incurred by the
Company in investigating such evidence and preparing such indemnity.  In case
of defacement, a replacement certificate will be issued conditioned on
delivery of the old certificate to the Company.

2.7    ISSUANCE UNDER SEAL; SIGNATURES

       All certificates for share or loan capital or other securities of the
Company (other than letters of allotment, scrip certificates and other like
documents) shall, except to the extent that the terms and conditions relating
thereto otherwise provide, be issued under the Seal.  The Board may by
resolution determine, either generally or in any particular case, that any
signatures on any such certificates need not be autographic but may be
affixed to such certificates by some mechanical means or may be printed
thereon or that such certificates need not be signed by any persons.

2.8    INCREASE OF CAPITAL

       The Company may from time to time increase its capital by such sum to
be divided into shares of such par value as the Company in general meeting
shall prescribe.

       Any new shares shall be subject to all the provisions of these
Bye-Laws with reference to forfeiture, transfer, transmission and otherwise.

                                 -4-

<PAGE>

means of loan, guarantee, provision of security or otherwise, any financial
assistance for the purpose of a purchase of subscription made or to be made
by any person of or for any shares in the Company, but nothing in this
Bye-Law shall prohibit transactions mentioned in Sections 39A, 39B and 39C of
the Act.

2.9    ALTERATION OF CAPITAL

       The Company may from time to time in general meeting;

respectively any preferential, deferred, qualified or special rights,
privileges or conditions;

       (b)    consolidate all or any of its share capital into shares of
larger par value than its existing shares;

       (c)    sub-divide its shares or any of them into shares of smaller par
value than is fixed by its memorandum;

       (e)    make provision for the issue and allotment of shares which do
not carry any voting rights; and

       (f)    cancel shares which, upon the passing of a resolution to that
effect, have not been taken or agreed to be taken by any person, and diminish
the amount of its share capital by the amount of the shares so canceled.

2.10   REDUCTION OF CAPITAL

       Subject to the Companies Act, its memorandum and any confirmation or
consent required by law or these Bye-Laws, the Company may from time to time
in general meeting authorize the reduction of its issued share capital or any
capital redemption reserve fund or any share premium or contributed surplus
account in any manner.  In relation to any such reduction, the Company may in
general meeting determine the terms upon which such reduction is to be
effected.

2.11   DIVIDENDS AND OTHER PAYMENTS

       (a)    Subject to any special rights provided pursuant to these
Bye-Laws and the provisions of Section 54 of the Act, the Board may from time
to time declare cash dividends to be paid to the Shareholders according to
their rights and interests in the profits including such interim dividends as
appear to the Board to be justified by the position of the Company.  The
Board may also pay any fixed cash dividend which is payable on any shares of
the Company half yearly or on such other dates, whenever the position of the
Company, in the opinion of the Board, justifies such payment.

       (b)    No dividend or other moneys payable by the Company on or in
respect of any shares shall bear interest against the Company.

                                 -5-

<PAGE>

       (c)    Any dividend, interest or other sum payable in cash to the
holder of shares may be paid by cheque or warrant sent through the post
addressed to the holder at his address in the Register or, in the case of
joint holders, addressed to the holder whose name stands first in the
Register in respect of the shares at his registered address as appearing in
the register or addressed to such person at such address as the holder or
joint holders may in writing direct.  Every such cheque or warrant shall,
unless the holder or joint holders otherwise direct, be made payable to the
order of the holder or, in the case of joint holders, to the order of the
holder whose name stands first in the Register in respect of such shares, and
shall be sent at his or their risk and payment of the cheque or warrant by
the bank on which it is drawn shall constitute a good discharge to the
Company.  Any one of two or more joint holders may give effectual receipts
for any dividends or other moneys payable or property distributable with
respect to the shares held by such joint holders.

       (d)    With the sanction of the Company in general meeting, the Board
may (a) declare a distribution to any Shareholder out of contributed surplus
and (b) may direct payment or satisfaction of such distribution or any
dividend wholly or in part by the distribution of specific assets, and may
fix the value for distribution or dividend purposes of any such specific
assets and may determine that cash payments shall be made to any Shareholder
upon the footing of the values so fixed in order to secure equality of
distribution and may vest such specific assets in trustees as may seem
expedient to the Board.

       (e)    Neither the Company nor any of its Subsidiaries shall make any
distribution to the Company's Shareholders on any shares of any class or
series which are junior to outstanding shares of any other class or series
with respect to distribution of assets on liquidation if, after giving effect
thereto, the excess of its assets (exclusive of goodwill, capitalized
research and development expenses and deferred charges) over its liabilities
(not including deferred taxes, deferred income and other deferred credits)
would be less than the liquidation preference of all shares having a
preference on liquidation over the class or series to which the distribution
is made; provided, however, that for the purpose of applying this section to
a distribution of cash or property in payment in whole or in part of an
obligation incurred by the Company in connection with the purchase of its
shares, there shall be deducted from liabilities any amount which had been
added thereto at the time the obligation was incurred, but not in excess of
the principal of the obligation which will remain unpaid after the
distribution.  Notwithstanding the foregoing, neither the Company nor any of
its Subsidiaries shall make any distribution to the Company's Shareholders on
any shares of its stock of any class or series which are junior to
outstanding shares of any other class or series at any time that such senior
securities are outstanding.

       (f)    Neither the Company nor any of its Subsidiaries shall make any
distribution to the Company's Shareholders on any shares of any class or
series which are junior to outstanding shares of any other class or series
with respect to payment of dividends unless the amount of the retained
earnings of the Company immediately prior thereto equals or exceeds the
amount of the proposed distribution plus the aggregate amount of the
cumulative dividends in arrears on all shares having a preference with
respect to payment of dividends over the class or series to which the
distribution is made; provided, however, that for the purpose of applying
this section to a distribution of cash or property in payment in whole or in
part of an obligation incurred by the Company in connection with the purchase
of its shares, there shall be added to retained earnings any amount that had
been deducted therefrom at the time the obligation was incurred, but not in
excess of the principal of the obligation which remains unpaid immediately
prior to the distribution. Notwithstanding the foregoing, neither the Company
nor any of its Subsidiaries shall make any distribution to the Company's
Shareholders on any shares of its stock of any class or series which are
junior to outstanding shares of any other class or series at any time that
such senior securities are outstanding.

<PAGE>

       (g)    Sections 2.11(e) and (f) shall not apply to a purchase or
redemption of shares of a deceased or disabled Shareholder from the proceeds
of life insurance or disability insurance in excess of the total amount of
all premiums paid by the Company for such insurance, in order to carry out
the provisions of an agreement between the Company and such Shareholder to
purchase or redeem such shares upon the death or disability of the
Shareholder. Sections 2.11(e) and (f) also shall not apply to distributions
made by the Company and approved by the Board of Directors in connection with
the repurchase of Common Shares issued to or held by directors, officers,
employees and consultants of the Company upon termination of their employment
or services pursuant to agreements providing the Company such a right of
repurchase.

2.12   RESERVES

       The Board may, before recommending or declaring any dividend, set
aside out of the profits of the Company such sums as it thinks proper as
reserves which shall, at the discretion of the Board, be applicable for any
purpose to which the profits of the Company may be properly applied and
pending such application may, also at such discretion, either be employed in
the business of the Company or be invested in such investments as the Board
may from time to time think fit.  The Board may also without placing the same
to reserve carry forward any profits which it may think it prudent not to
distribute.

2.13   REGISTER OF SHAREHOLDERS

       In accordance with this Section 2.13 and Section 6.4 below, the
Secretary shall establish and maintain the Register of Shareholders at the
Registered Office in the manner prescribed by the Companies Act.  Unless the
Board otherwise determines, the Register of Shareholders shall be open to
inspection in the manner prescribed by the Companies Act between 10:00 a.m.
and 12:00 noon on every working day.

2.14   REGISTER OF DIRECTORS AND OFFICERS

       The Secretary shall establish and maintain a register of the Directors
and Officers of the Company as required by the Companies Act.

       The register of Directors and Officers shall be open to inspection in
the manner prescribed by the Companies Act between 10:00 a.m. and 12:00 noon
on every working day.

2.15   TRANSFER OF SHARES

       Subject to the Companies Act and to such of the restrictions contained
in these Bye-Laws as may be applicable, and to such agreements as may be
binding upon such Shareholder from time to time,  any Shareholder may
transfer all or any of his shares by an instrument of transfer in the usual
common form or in any other form which the Board may approve.

       No fee shall be charged by the Company for registering any transfer,
probate, letters of administration, certificate of death or marriage, power
of attorney, restraining order or stop notice, order of court or other
instrument relating to or affecting the title to any share, or otherwise
making an entry in the Register relating to any share, if properly executed
by the appropriate party or by a court of competent jurisdiction.

<PAGE>

2.16   TRANSMISSION OF SHARES

       For the purpose of this Section 2.16, legal personal representative
shall mean the person to whom probate or letters of administration has or
have been granted in Bermuda or, failing any such person, such other person
as the Board may in its absolute discretion determine to be the person
recognized by the Company for the purpose of this Section 2.16.

       In the case of the death of a Shareholder, the survivor or survivors,
where the deceased was a joint holder, and the legal personal representative,
where he was sole holder, shall be the only person recognized by the Company
as having any title to his shares.  Nothing herein contained shall release
the estate of a deceased holder (whether the sole or joint) from any
liability in respect of any share held by him solely or jointly with other
persons.

       Any person becoming entitled to a share as a consequence of the death
of a Shareholder or otherwise by operation of applicable law may, subject as
hereafter provided and upon such evidence being produced as may from time to
time be required by the Board as to his entitlement, either be registered
himself as the holder of the share or elect to have some person nominated by
him registered as the transferee thereof.  If the person so becoming entitled
elects to be registered himself, he shall deliver or send to the Company a
notice in writing signed by him stating that he so elects.  If he shall elect
to have his nominee registered, he shall signify his election by signing an
instrument of transfer of such share in favor of his nominee.  All the
limitations, restrictions and provisions of these Bye-Laws relating to the
right to transfer and the registration of transfer of shares shall be
applicable to any such notice or instrument of transfer as aforesaid as if
the death of the Shareholder or other event giving rise to the transmission
had not occurred and the notice or instrument of transfer was an instrument
of transfer signed by such Shareholder.

       A person becoming entitled to a share as a consequence of the death of
a Shareholder or otherwise by operation of applicable law shall (upon
delivering such evidence as may from time to time be required by the Board as
to his entitlement) be entitled to receive and may give a discharge for any
dividends or other moneys payable in respect to the share, but he shall not
be entitled in respect of the share to receive notices of or to attend or
vote at general meetings of the Company or, save as aforesaid, to exercise in
respect of the share any of the rights or privileges of a Shareholder until
he shall have become registered as the holder thereof.  The Board may at any
time give notice requiring such person to elect either to be registered
himself or to transfer the share and if the notice is not complied with
within sixty days the Board may thereafter withhold payment of all dividends
and other moneys payable in respect of the shares until the requirements of
the notice have been complied with.

       Subject to any directions of the Board from time to time in force, the
Secretary may exercise the powers and discretions of the Board under this
Section 2.16.

2.17   RECORD DATES

       Notwithstanding any other provisions of these Bye-Laws the Company in
general meeting or the Board may fix any date as the record date for any
dividend, distribution, allotment or issue and for the purpose of identifying
the persons entitled to receive notices of general meetings and proxy
solicitation materials.  Any such record date may be on or at any time before
or after any date on which such dividend, distribution, allotment or issue is
declared, paid or made or such notice is dispatched.

                                   -8-

<PAGE>

2.18   SERVICE OF NOTICES AND OTHER DOCUMENTS

       Any notice or other document (including a share certificate) may be
served on or delivered to any Shareholder by the Company either personally or
by sending it through the post (by airmail where applicable) in a pre-paid
letter addressed to such Shareholder at his address as appearing in the
Register or by delivering it to or leaving it at such registered address.  In
the case of joint holders of a share, service or delivery of any notice or
other document on or to one of the joint holders shall for all purposes be
deemed as sufficient service on or delivery to all the joint holders.  Any
notice or other document if sent by post shall be deemed to have been served
or delivered seven days after it was put in the post, and in proving such
service or delivery, it shall be sufficient to prove that the notice or
document was properly addressed, stamped and put in the post.

       Any notice of a general meeting of the Company shall be deemed to be
duly given to a Shareholder if it is sent to him by cable, telex, telecopier
or other mode of representing or reproducing words in a legible and
non-transitory form at his address as appearing in the Register or any other
address given by him to the Company for this purpose.  Any such notice shall
be deemed to have been served twenty-four hours after its dispatch.

       Any notice or other document delivered, sent or given to a Shareholder
in any manner permitted by these Bye-Laws shall, notwithstanding that such
Shareholder is then dead or bankrupt or that any other event has occurred,
and whether or not the Company has notice of the death or bankruptcy or other
event, be deemed to have been duly served or delivered in respect of any
share registered in the name of such Shareholder as sole or joint holder
unless his or her name shall, at the time of the service or delivery of the
notice or document, have been removed from the Register as the holder of the
share, and such service or delivery shall for all purposes be deemed as
sufficient service or delivery of such notice or document on all persons
interested (whether jointly with or as claiming through or under him) in the
share.

                             ARTICLE III -- SHARE RIGHTS


3.1    SHARE CAPITAL

       (a)    The capital of the Company shall be divided into such shares
with the rights and restrictions contained in these Bye-Laws as follows:

              (i)    The total number of Preferred Shares which the Company
shall have authority to issue shall be 10,000,000, US$0.001 par value.  The
Preferred Shares may be issued from time to time in one or more series
pursuant to a resolution or resolutions providing for such issue duly adopted
by the Board of Directors (authority to do so being hereby expressly vested in
the Board).  The Board of Directors is further authorized to determine or
alter the rights, preferences, privileges and restrictions granted to or
imposed upon any wholly unissued series of Preferred Shares and to fix the
number of shares of any series of Preferred Shares and the designation of any
such series of Preferred Shares.  The board of Directors, within the limits
and restrictions stated in any resolution or resuolutions of the Board of
Directors originally fixing the number of shares constituting any series, may
increase or decrease (but not below the number of shares in any such series
then outstanding), the number of shares of any series subsequent to the issue
of shares of that series.

              (ii)   100,000,000 of Common Shares of a par value of US$0.001,
the holders of which shall, subject to the provisions of these Bye-laws:

                     (1)    be entitled to one vote per Common Share;

                     (2)    be entitled to such dividends as the Directors
may from time to time declare with respect to such Common Shares;

                     (3)    in the event of a winding-up or dissolution of
the Company, whether voluntary or involuntary or for the purposes of a
reorganization or otherwise or upon any distribution of capital, be entitled
to an amount equal to the par value per Common Share and thereafter to all
the surplus assets attributable to such Common Shares.

                        ARTICLE IV -- MEETINGS

4.1    GENERAL MEETINGS

       The Board shall convene and the Company shall hold Annual General
Meetings in accordance with the requirements of the Companies Act at such
times and places as the Board shall appoint.

4.2    SPECIAL GENERAL MEETINGS

       A special general meeting of the Shareholders may be called at any
time by the Board, or by the chairman of the Board, or by the president, or
by one or more Shareholders holding shares in the aggregate entitled to cast
not less than ten percent (10%) of the votes at that meeting.

       If a special meeting is called by any person other than the board of
directors, the request shall be in writing, specifying the time of such
meeting and the general nature of the business proposed to be transacted, and
shall be delivered personally or sent by registered mail or by telegraphic or
other facsimile transmission to the chairman of the board, the president, any
vice president, or the secretary of the corporation. No business may be
transacted at such special meeting otherwise than specified in such notice.
The officer receiving the request shall cause notice to be promptly given to
the stockholders entitled to vote, in accordance with the provisions of
Sections 4.4 of this Article IV, that a meeting will be held at the time
requested by the person or

                                   -10-

<PAGE>

persons who called the meeting, not less than ten(10) nor more than sixty
(60) days after the receipt of the request.  Nothing contained in this
paragraph of this Section 4.2 shall be construed as limiting, fixing, or
affecting the time when a meeting of stockholders called by action of the
board of directors may be held.

4.3    TELEPHONE MEETINGS

       A meeting of the Shareholders or any class or series thereof may be
held by means of such telephone, electronic or other communication facilities
as permit all persons participating in the meeting to communicate with each
other simultaneously and instantaneously, and participating in such a meeting
shall constitute presence in person at such meeting.

4.4    ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND STOCKHOLDER BUSINESS

       Subject to the rights of holders of any class or series of stock
having a preference over the Common Stock as to dividends or upon liquidation,

       (a)    nominations for the election of directors, and

       (b)    business proposed to be brought before any stockholder meeting
may be made by the board of directors or proxy committee appointed by the
board of directors or by any stockholder entitled to vote in the election of
directors generally if such nomination or business proposed is otherwise
proper business before such meeting. However, any such stockholder may
nominate one or more persons for election as directors at a meeting or propose
business to be brought before a meeting, or both, only if such stockholder
has given timely notice in proper written form of their intent to make such
nomination or nominations or to propose such business. To be timely, such
stockholder's notice must be delivered to or mailed and received at the
principal executive offices of the corporation not less than one hundred
twenty (120) calendar days in advance of the date specified in the
corporation's proxy statement released to stockholders in connection with the
previous year's annual meeting of stockholders; provided, however, that in
the event that no annual meeting was held in the previous year or the date of
the annual meeting has been changed by more than thirty (30) days from the
date contemplated at the time of the previous year's proxy statement, notice
by the stockholder to be timely must be so received a reasonable time before
the solicitation is made. To be in proper form, a stockholder's notice to the
secretary shall set forth:

             (i)     the name and address of the stockholder who intends to
make the nominations or propose the business and, as the case may be, of the
person or persons to be nominated or of the business to be proposed;

              (ii)   a representation that the stockholder is a holder of
record of stock of the corporation entitled to vote at such meeting and, if
applicable, intends to appear in person or by proxy at the meeting to
nominate the person or persons specified in the notice;

              (iii)  if applicable, a description of all arrangements or
understandings between the stockholder and each nominee and any other person
or persons (naming such person or persons) pursuant to which the nomination
or nominations are to be made by the stockholder;

              (iv)   such other information regarding each nominee or each
matter of business to be proposed by such stockholder as would be required to
be included in a proxy statement filed pursuant to the proxy rules of the
Securities and Exchange Commission had the nominee been nominated, or
intended to be nominated, or the matter been proposed, or intended to be
proposed by the board of directors; and

              (v)    if applicable, the consent of each nominee to serve as
director of the corporation if so elected.

       The chairman of the meeting shall refuse to acknowledge the nomination
of any person or the proposal of any business not made in compliance with the
foregoing procedure.

4.5    PROCEEDINGS AT GENERAL MEETINGS

       No business shall be transacted at any general meeting unless a quorum
is present when the meeting proceeds to business, but the absence of a quorum
shall not preclude the appointment, choice or election of a Chairman which
shall not be treated as part of the business of the meeting.  The presence in
person or by proxy of the holders of a majority of the shares entitled to
vote thereat constitutes a quorum for the transaction of business at all
meetings of Shareholders.  Notwithstanding the foregoing, no business may be
transacted at any general meeting of Shareholders unless at least two
Shareholders are present at the meeting in person.  The Shareholders present
in person or by proxy at a duly called or held meeting at which a quorum is
present may continue to do business until adjournment, notwithstanding the
withdrawal of enough Shareholders to leave less than a quorum, if any action
taken (other than adjournment) is approved at such meeting by at least a
majority of the shares required to constitute a quorum.

       If within five minutes (or such longer time as the Chairman of the
meeting may determine to wait) after the time appointed for the meeting, a
quorum is not present, the meeting, if convened on the requisition of
Shareholders, shall be dissolved.  In any other case, it shall stand
adjourned to such other day and such other time and place as the Chairman of
the meeting may determine and at such adjourned meeting two Shareholders
present in person (whatever the number of shares held by them) shall be a
quorum.

       Each Director shall be entitled to attend and speak at any general
meeting of the Company.

                                   -11-

<PAGE>

4.6    CHAIRMAN

       The Chairman (if any) of the Board or, in his absence, the President
shall preside as Chairman at every general meeting.  If there is no such
Chairman or President, or if at any meeting neither of the Chairman nor the
President is present within five minutes after the time appointed for holding
the meeting, or if neither of them is willing to act as Chairman, the
Directors present shall choose one of their number to act or if one Director
only is present he shall preside as Chairman if willing to act.  If no
Director is present or, if each of the Directors present declines to take the
chair, the persons present and entitled to vote on a poll shall elect one of
their number to be Chairman.

       The Chairman may, with the consent of any meeting at which a quorum is
present (and shall if so directed by the meeting), adjourn the meeting from
time to time and from place to place but no business shall be transacted at
any adjourned meeting except business which might lawfully have been
transacted at the meeting from which the adjournment took place.  When a
meeting is adjourned for thirty days or more, notice of the adjourned meeting
shall be given as in the case of an original meeting.

       Save as expressly provided by these Bye-Laws, it shall not be
necessary to give any notice of an adjournment or of the business to be
transacted at an adjourned meeting.

4.7    VOTING

       Save where a greater majority is required by the Companies Act or
these Bye-Laws, any question proposed for consideration at any general
meeting shall be decided on by a simple majority of votes cast.

       At any general meeting, a resolution put to the vote of the meeting
shall be decided on a show of hands unless (before or on the declaration of
the result of the show of hands or on the withdrawal of any other demand for
a poll) a poll is demanded by:

       (a)    the Chairman of the meeting or any Director; or

       (b)    at least three Shareholders present in person or represented by
proxy; or

       (c)    any Shareholder or Shareholders present in person or
represented by proxy and holding between them not less than five percent (5%)
of the total voting rights of all the Shareholders having the right to vote
at such meeting; or

       (d)    a Shareholder or Shareholders present in person or represented
by proxy holding shares conferring the right to vote at such meeting, being
shares on which an aggregate sum has been paid up equal to not less than five
percent (5%) of the total sum paid up on all such shares conferring such
right.

       Unless a poll is so demanded and the demand is not withdrawn, a
declaration by the Chairman that a resolution has, on a show of hands, been
carried or carried unanimously or by a particular majority or not carried by
a particular majority or lost shall be final and conclusive, and an entry to
that effect in the Minute Book of the Company shall be conclusive evidence of
the fact without proof of the number of votes recorded for or against such
resolution.

       If a poll is duly demanded, the result of the poll shall be deemed to
be the resolution of the meeting at which the poll is demanded.

                                     -12-

<PAGE>

       Any poll demanded shall be taken forthwith.

       The demand for a poll shall not prevent the continuance of a meeting
for the transaction of any business other than the question on which the poll
has been demanded and it may be withdrawn at any time before the close of the
meeting or the taking of the poll, whichever is earlier.

       On a poll, votes may be cast either personally or by proxy.

       A person entitled to more than one vote on a poll need not use all his
votes or cast all the votes he uses in the same way.

       In the case of an equality of votes at a general meeting, whether on a
show of hands or on a poll, the Chairman of such meeting shall not be
entitled to a second or casting vote.

       In the case of joint holders of a share, the vote of the senior who
tenders a vote, whether in person or by proxy, shall be accepted to the
exclusion of the votes of the other joint holders, and for this purpose
seniority shall be determined by the order in which the names stand in the
Register in respect of the joint holding.

       A Shareholder who is a patient for any purpose of any statute or
applicable law relating to mental health or in respect of whom an order has
been made by any Court having jurisdiction for the protection or management
of the affairs of persons incapable of managing their own affairs may vote,
whether on a show of hands or on a poll, by his receiver, committee, curator
bonis or other person in the nature of a receiver, committee or curator bonis
or other person may vote on a poll by proxy, and may otherwise act and be
treated as such Shareholder for the purpose of general meetings.

       No Shareholder shall, unless the Board otherwise determines, be
entitled to vote at any general meeting unless all calls or other sums
presently payable by him in respect of shares in the Company have been paid.

       If (i) any objection shall be raised to the qualification of any voter
or (ii) any votes have been counted which ought not been counted or which
might have been rejected or (iii) any votes are not counted which ought to
have been counted, the objection or error shall not vitiate the decision of
the meeting or adjourned meeting on any resolution unless the same is raised
or pointed out at the meeting or, as the case may be, the adjourned meeting
at which the vote objected to is given or tendered or at which the error
occurs.  Any objection or error shall be referred to the Chairman of the
meeting and shall only vitiate the decision of the meeting on any resolution
if the Chairman decides that the same may have affected the decision of the
meeting.  The decision of the Chairman on such matters shall be final and
conclusive.

4.9    CORPORATE TRANSACTIONS

       (a)    AMALGAMATION OR MERGER:  An amalgamation or merger of the
Company with or into another corporation, shall be approved by  the
affirmative vote of a majority of the outstanding shares entitled to vote.

       (b)    SALE OF ASSETS:  A sale, lease, conveyance, exchange, transfer
or other disposal of all or substantially all of the Company's assets (with
the exception of transactions which are, in the judgment of the Board, in the
usual and regular course of the Company's business) shall be approved by the
affirmative vote of a majority of the outstanding shares entitled to vote.

       (c)    SHARE EXCHANGE:  Any transaction in which the Company acquires
shares of another corporation in exchange in whole or in part for its equity
securities (or the equity securities of a corporation which is in control of
the Company), whereby, immediately after the acquisition, the Company has
control of the other corporation, shall be approved by the affirmative vote
of a majority of the outstanding shares entitled to vote.

       (d)    EXCEPTIONS:  No approval of the outstanding shares will be
required under subsection (c) of this Section 4.9 if the Company, or its
Shareholders immediately before the reorganization, or both, shall own
(immediately after the reorganization) equity securities, other than any
warrant or right to subscribe to or purchase such equity securities, of the
surviving or acquiring corporation or a parent party possessing more than
five-sixths of the voting power of the surviving or acquiring corporation or
parent party.  In making the determination of ownership by the Shareholders
of the Company, immediately after the reorganization, of equity securities
pursuant to the preceding sentence, equity securities which Shareholders
owned immediately before the reorganization as Shareholders of another party
to the transaction shall be disregarded.  For the purpose of this section
only, the voting power of a corporation shall be calculated by assuming the
conversion of all equity securities convertible, immediately or at some
future time, into shares entitled to vote but not assuming the exercise of
any warrant or right to subscribe to or purchase such shares.

       (e)    VOTING REQUIREMENTS:  The voting requirements in this Section
4.9 are in addition to any voting requirements set forth in the Companies Act
or elsewhere in these Bye-Laws.

4.10   PROXIES AND CORPORATE REPRESENTATIVES

       The instrument appointing a proxy shall be in writing under the hand
of the appointor or of his attorney authorized by him in writing or, if the
appointor is a corporation, either under its seal or under the hand of an
officer, attorney or other person authorized to sign the same.

       Any Shareholder may appoint a standing proxy or (if a corporation)
representative by depositing at the Registered Office a proxy or (if a
corporation) an authorization and such proxy or authorization shall be valid
for all general meetings and adjournments thereof until notice of revocation
is received at the Registered Office.  Where a standing proxy or
authorization exists, its operation shall be deemed to have been suspended at
any general meeting or adjournment thereof at which the Shareholder is
present or in respect to which the Shareholder has specially appointed a
proxy or representative.  The Board may from time to time require such

                                 -14-

<PAGE>

evidence as it shall deem necessary as to the due execution and continuing
validity of any such standing proxy or authorization, which shall be deemed
to be suspended until such time as the Board determines that it has received
the requested evidence or other evidence satisfactory to it.

       Subject to this Section 4.10, the instrument appointing a proxy
together with such other evidence as to its due execution as the Board may
from time to time require, shall be delivered at the Registered Office (or at
such place as may be specified in the notice convening the meeting or in any
notice of any adjournment or, in either case, in any document sent therewith)
prior to the holding of the meeting or adjourned meeting at which the person
named in the instrument proposed to vote or, in the case of a poll taken
subsequently to the date of a meeting or adjourned meeting, before the time
appointed for the taking of the poll and in default the instrument of proxy
shall not be treated as valid.

       Instruments of proxy shall be in any common form or in such other form
as the Board may approve and the Board may, if it thinks fit, send out with
the notice of any meeting forms of instruments of proxy for use at that
meeting. The instrument of proxy shall be deemed to confer authority to
demand or join in demanding a poll and to vote on any amendment of a
resolution put to the meeting for which it is given as the proxy thinks fit.
The instrument of proxy shall unless the contrary is stated therein be valid
as well for any adjournment of the meeting as for the meeting to which it
relates.

       A vote given in accordance with the terms of an instrument of proxy
shall be valid notwithstanding the previous death or insanity of the
principal, or revocation of the instrument of proxy or of the authority under
which it was executed, provided that no intimation in writing of such death,
insanity or revocation shall have been received by the Company at the
Registered Office (or such other place as may be specified for the delivery
of instruments of proxy in the notice convening the meeting or other
documents sent therewith) one hour at least before the commencement of the
meeting or adjourned meeting, or the taking of the poll, at which the
instrument of proxy is used.

       Subject to the Companies Act, the Board may at its discretion waive
any of the provisions of these Bye-Laws related to proxies or authorizations
and, in particular, may accept such verbal or other assurances as it thinks
fit as to the right of any person to attend and vote on behalf of any
Shareholder at general meetings.

4.11   SHAREHOLDER ACTION BY UNANIMOUS WRITTEN CONSENT WITHOUT A MEETING

       Subject to the Companies Act, any action required or permitted to be
taken by the Shareholders may be taken without a meeting, provided that all
Shareholders consent in writing to that action. Such action by written
consent shall have the same force and effect as a unanimous vote of the
Shareholders. Such written consent and any counterparts thereof shall be
filed with the minutes of the proceedings of the Shareholders.

                        ARTICLE V -- DIRECTORS

5.1    POWERS AND DUTIES OF THE BOARD

       Subject to the provisions of the Companies Act and these Bye-Laws and
to any direction given by the Company in general meeting, the Board shall
manage the business of the Company and may pay all expenses incurred in
promoting and incorporating the Company and may exercise all the powers of
the Company.  No alteration of these Bye-Laws and no such director shall
invalidate any prior act of the Board which would have been valid if that
alteration had not been made or that direction had not been given.  The
powers given to the Board by these Bye-Laws and a meeting of the Board at
which a quorum is present shall be competent to exercise all the powers,
authorities and discretions for the time being vested in or exercisable by
the Board.

                                    -15-

<PAGE>

       The Board may exercise all the powers to borrow money and to mortgage
or charge all or any part of the undertaking, property and assets (present
and future) and uncalled capital of the Company and to issue debentures and
other securities, whether outright or as collateral security for any debt,
liability or obligation of the Company or of any other persons.

       All cheques, promissory notes, drafts, bills of exchange and other
instruments, whether negotiable or transferable or not, and all receipts for
money paid to the Company shall be signed, drawn, accepted, endorsed or
otherwise executed, as the case may be, in such manner as the Board shall
from time to time by resolution determine.

       The Board on behalf of the Company may provide benefits, whether by
the payment of gratuities or pensions or otherwise, for any person including
any Director or former Director who has held any executive office or
employment with the Company or with any body corporate which is or has been a
subsidiary or affiliate of the Company or a predecessor in the business of
the Company or of any such subsidiary or affiliate, and to any member of his
family or any person who is or was dependent on him, and may contribute to
any fund and pay premiums for the purchase or provision of any such gratuity,
pension or other benefit, or for the insurance of any such person.

       The Board may, with the approval of the President, from time to time
appoint one or more of its body to be a managing director, joint managing
director or an assistant managing director or to hold any other employment or
executive office with the Company for such period and upon such terms as the
Board may determine and may revoke or terminate any such appointments.  Any
such revocation or termination as aforesaid shall be without prejudice to any
claim for damages that such Director may have against the Company or the
Company may have against such Director for any breach of any contract of
service between him and the Company which may be involved in such revocation
or termination.  Any person so appointed shall receive such remuneration (if
any) (whether by way of salary, commission, participation in profits or
otherwise) as the Board may determine, and either in addition to or in lieu
of his remuneration as a Director.

       The Board may, from time to time without the approval of the
Shareholders of the Company, but subject to the requirements of the Companies
Act, authorize, and cause the Company to repurchase any of its issued and
outstanding shares.

5.2    DELEGATION OF THE BOARD'S POWERS

       The Board may, by power of attorney, appoint any company, firm or
person or any fluctuating body of persons, whether nominated directly or
indirectly by the Board, to be the attorney or attorneys of the Company for
such purposes and with such powers, authorities and discretions (not
exceeding those vested in or exercisable by the Board under these Bye-Laws)
and for such period and subject to such conditions as it may think fit, and
any such power of attorney may contain such provisions for the protection and
convenience of persons dealing with any such attorney and of such attorney as
the Board may think fit, and may also authorize any such attorney to
sub-delegate all or any of the powers, authorities and discretions vested in
him.

       The Board may entrust to and confer upon any Director or officer any
of the powers exercisable by it upon such terms and conditions with such
restrictions as it thinks fit, and either collaterally with, or to the
exclusion of, its own powers, and may from time to time revoke or vary all or
any of such powers but no person dealing in good faith and without notice of
such revocation or variation shall be affected thereby.

                                    -16-

<PAGE>

       The Board may delegate any of its powers, authorities and discretions
to committees, consisting of such person or persons (whether a member or
members of its body or not) as it thinks fit.  Any committee so formed shall,
in the exercise of the powers, authorities and discretions so delegated,
conform to any regulations which may be imposed upon it by the Board.

5.3    NUMBER

       The authorized number of directors of the Company shall be nine members.
No reduction of the authorized number of directors shall have the effect of
removing any director before that director's term of office expires.

5.4    CLASSES OF DIRECTORS

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

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

5.5    APPOINTMENT AND REMOVAL OF DIRECTORS

       Subject to the Companies Act and these Bye-Laws, a director shall hold
office until the expiration of the term for which elected and until a
successor has been qualified and elected.

       The Shareholders shall at the Annual General Meeting and may in any
general meeting determine the minimum and the maximum number of Directors and
may in general meeting determine that one or more vacancies in the Board
shall be deemed casual vacancies for the purposes of these Bye-Laws.  Without
prejudice to the power of the Company in general meeting in pursuance of any
of the provisions of these Bye-Laws to appoint any person to be a Director,
the Board, so long as a quorum of Directors remains in office, shall have
power at any time and from time to time to appoint any Shareholder being an
individual to be a Director so as to fill a casual vacancy.

       The Company may in a Special General Meeting called for that purpose
remove a Director provided notice of any such meeting shall be served upon
the Director concerned not less than 14 days before the meeting and he shall
be entitled to be heard at that meeting.  No Director may be removed (unless
the entire Board is removed) when the votes cast against the removal would be
sufficient to elect the Director if voted cumulatively at an election at
which the same total number of votes were cast and the entire number of
Directors authorized at the time of the Director's most recent election were
then being elected.  Any vacancy

                                   -17-

<PAGE>

created by the removal of a Director at a Special General Meeting may be
filled at the Meeting by the election of another Director in his place or, in
the absence of any such election, by the Board.

5.6    RESIGNATION AND DISQUALIFICATION OF DIRECTORS

       The office of a Director shall be vacated upon the happening of any of
the following events:

       (a)    if he resigns his office by notice in writing delivered to the
Registered Office or tendered at a meeting of the Board;

       (b)    if he becomes of unsound mind or a patient for any purpose of
any statute or applicable law relating to mental health and the Board
resolves that his office is vacated;

       (c)    if he becomes bankrupt or compounds with his creditors;

       (d)    if he is prohibited by law from being a Director;

       (e)    if he ceases to be a Director by virtue of the Companies Act or
is removed from office pursuant to these Bye-Laws.

5.7    ALTERNATE DIRECTORS

       The Company may in general meeting elect a person or persons qualified
to be Directors to act as Directors in the alternative to any of the
Directors of the Company or may authorize the Board to appoint such Alternate
Directors. Additionally, unless otherwise resolved by the Shareholders, a
Director may appoint an Alternate Director to act as a Director in his or her
stead by notifying the Secretary in writing of such appointment.  Any
Alternate Director may be removed by the Company in general meeting, and if
appointed by the Board, may be removed by the Board and, subject thereto, the
office of Alternate Director shall continue until the next annual election of
Directors or, if earlier, the date on which the relevant Director ceases to
be a Director.  An Alternate Director may also be a Director in his own right
and may act as alternate to more than one Director.

       An Alternate Director shall be entitled to receive notices of all
meetings of Directors, to attend, be counted in the quorum and vote at any
such meeting at which any Director to whom he is alternate is not personally
present, and generally to perform all the functions of any Director to whom
he is an alternate in his absence.

       Any person acting as an Alternate Director shall (except as regards
powers to appoint an alternate and remuneration) be subject in all respects
to the provisions of these Bye-Laws relating to Directors and shall alone be
responsible to the Company for his acts and defaults and shall not be deemed
to be the agent of or for any Director for whom he is alternate.  An
Alternate Director may be paid expenses and shall be entitled to be
indemnified by the Company to the same extent as if he were a Director.
Every person acting as an Alternate Director shall have one vote for each
Director for whom he acts as alternate (in addition to his own vote if he is
also a Director).  The signature of an Alternate Director to any resolution
in writing of the Board or a

                                     -18-

<PAGE>

committee of the Board shall, unless the terms of his appointment provides to
the contrary, be as effective as the signature of the Director or Directors
to whom he is an alternate.

5.8    DIRECTORS' FEES AND ADDITIONAL REMUNERATION AND EXPENSES

       The amount, if any, of Directors' fees shall from time to time be
determined by the Shareholders of the Company in a general meeting and in the
absence of a determination to the contrary in general meeting, such fees
shall be deemed to accrue from day to day.  Each Director may be paid his
reasonable traveling, hotel and incidental expenses in attending and
returning from meetings of the Board or committee constituted pursuant to
these Bye-Laws or general meetings and shall be paid all expenses properly
and reasonably incurred by him in the discharge of his duties as a Director.
Any Director who, by request, goes or resides abroad for any purposes of the
Company or who performs services which in the opinion of the Board go beyond
the ordinary duties of a Director may be paid such extra remuneration
(whether by way of salary, commission, participation in profits or otherwise)
as the Board may determine, and such extra remuneration shall be in addition
to any remuneration provided for by or pursuant to any other Bye-Law.

5.9    PLACE OF MEETINGS; TELEPHONE MEETINGS

       Regular meetings of the Board may be held at any place within or
outside of Bermuda that has been designated from time to time by resolution
of the Board.  In the absence of such a designation, regular meetings shall
be held at the principal business office of the Company.  Special meetings of
the Board may be held at any place within or outside Bermuda that has been
designated in the notice of the meeting or, if not stated in the notice, at
the registered office of the Company.

       Any meeting, regular or special, of the Board or a committee appointed
by the Board may be held by means of such telephone, electronic or other
communication facilities as permit all persons participating in the meeting
to communicate with each other simultaneously and instantaneously, and
participation in such a meeting shall constitute presence in person at such
meeting.

5.10   DIRECTOR'S INTERESTS

       (a)    A Director may hold any other office or place of profit with
the Company (except that of auditor) in conjunction with his office of
Director for such period and upon such terms as the Board may determine, and
may be paid such extra remuneration therefor (whether by way or salary,
commission, participation in profits or otherwise) as the Board may
determine, and such extra remuneration shall be in addition to any
remuneration provided for by or pursuant to any other Bye-Law.

       (b)    A Director may act by himself or his firm in a professional
capacity for the Company (otherwise than as auditor) and he or his firm shall
be entitled to remuneration for professional services as if he were not a
Director.

       (c)    Subject to the provisions of the Companies Act, a Director may,
notwithstanding his office be a party to, or otherwise interested in, any
transaction or arrangement with the Company or in which the Company is
otherwise interested; and be a Director or other officer of, or employed by,
or a party to any transaction or arrangement with, or otherwise interested
in, any body corporate promoted by the Company or in which the Company is
interested.  The Board may also cause the voting power conferred by the
shares in any other company held or owned by the Company to be exercised in
such manner in all respects as it thinks fit, including the exercise thereof
in favor of any resolution appointing the Directors or any of them to be

                                  -19-

<PAGE>

directors or officers of such other company, or voting or providing for the
payment of remuneration to the directors or officers of such other company.

       (d)    So long as, where it is necessary, he declares the nature of
his interest at the first opportunity at a meeting of the Board or by writing
to the Directors as required by the Companies Act, a Director shall not by
reason of his office be accountable to the Company for any benefits which he
derives from any office or employment to which these Bye-Laws allow him to be
appointed or from any transaction or arrangement in which these Bye-Laws
allow him to be interested, and no such transaction or arrangement shall be
liable to be avoided on the ground of any interest or benefit.

       (e)    Subject to the Companies Act and any further disclosure
required thereby, a general notice to the Directors by a Director or officer
declaring that he is a director or officer or has an interest in a person and
is to be regarded as interested in any transaction or arrangement made with
that person, shall be a sufficient declaration of interest in relation to any
transaction or arrangement so made.

5.11   PROCEEDINGS OF THE BOARD

       The Board may meet for the dispatch of business, adjourn and otherwise
regulate its meetings as it thinks fit.  Questions arising at any meeting

counted in the quorum until the termination of the Board meeting if no other
Director objects and if otherwise a quorum of Directors would not be present.

                    ARTICLE VIII -- INDEMNIFICATION

8.1    INDEMNIFICATION OF DIRECTORS AND OFFICERS OF THE COMPANY

       The Directors, Secretary and other Officers for the time being of the
Company and the liquidator or trustees (if any) for the time being acting in
relation to any of the affairs of the Company and every one of them, and
their heirs, executors and administrators, shall be indemnified and secured
harmless out of the assets of the Company from and against all actions,
costs, charges, losses, damages and expenses which they or any of them, their
heirs, executors or administrators, shall or may incur or sustain by or by
reason of any act done, concurred in or omitted in or about the execution of
their duty, or supposed duty, or in their respective offices or trusts, and
none of them shall be answerable for the acts, receipts, neglects or defaults
of the others of them or for joining in any receipts for the sake of
conformity, or for any bankers or other persons with whom any moneys or
effects belonging to the Company shall or may be lodged or deposited for safe
custody, or for insufficiency or deficiency of any security upon which any
moneys of or belonging to the

                                  -24-

<PAGE>

Company shall be placed out on or invested, or for any other loss, misfortune
or damage which may happen in the execution of their respective offices or
trusts, or in relation thereto, PROVIDED THAT this Indemnity shall not extend
to any matter in respect of any fraud or dishonesty which may attach to any
of said persons.

8.2    WAIVER OF CLAIM BY SHAREHOLDER


       Each Shareholder agrees to waive any claim or right of action such
Shareholder might have, whether individually or by or in the right of the
Company, against any Director or Officer on account of any action taken by
such Director or Officer in his or her capacity as such, or the failure of
such Director or Officer to take any action in the performance of his duties
with or for the Company, PROVIDED THAT such waiver shall not extend to any
matter in respect of any fraud or dishonesty which may attach to such
Director or Officer nor to any matter in which a Director or Officer fails to
discharge his duty to act honestly and in good faith with a view towards the
best interests of the Company. Notwithstanding the foregoing, this waiver of
claims does not apply to claims arising under the United States federal
securities laws, and claims arising under such laws are hereby specifically
excluded from this waiver.


8.3    INDEMNIFICATION OF OTHERS

       The Company shall have the power, to the extent and in the manner
permitted by the Companies Act, to indemnify each of its employees and agents
(other than directors and officers) against expenses judgments, fines,
settlements, and other amounts actually and reasonably incurred in connection
with any proceeding, arising by reason of the fact that such person is or was
an agent of the Company.  For purposes of this Article VIII, an "employee" or
"agent" of the Company (other than a director or officer) includes any person
(i) who is or was an employee or agent of the Company (ii) who is or was
serving at the request of the Company as an employee or agent of another
corporation partnership, joint venture, trust or other enterprise, or (iii)
who was an employee or agent of a Company which was a predecessor corporation
of the Company or of another enterprise at the request of such predecessor
corporation.

8.4    PAYMENT OF EXPENSES IN ADVANCE

       Subject to the Companies Act, expenses incurred in defending any civil
or criminal action or proceeding for which indemnification is required
pursuant to Section 8.1 or for which indemnification is permitted pursuant to
Section 8.2 following authorization thereof by the Board shall be paid by the
Company in advance of the final disposition of such action or proceeding upon
receipt of an undertaking by or on behalf of the indemnified party to repay
such amount if it shall ultimately be determined that the indemnified party
is not entitled to be indemnified as authorized in this Article VIII.

       Each Shareholder of the Company, by virtue of his acquisition and
continued holding of a share, shall be deemed to have acknowledged and agreed
that advances of funds made by the Company to a Director under this Section
are made to meet expenditures incurred for the purpose of enabling such
Director to properly perform his or her duties as an officer of the Company.

8.5    INDEMNITY NOT EXCLUSIVE

       The indemnification provided by this Article VIII shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any Bye-Law, agreement, vote of Shareholders or disinterested
directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the Memorandum.

                                   -25-

<PAGE>

8.6    INSURANCE INDEMNIFICATION

       The Company shall have the power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of
the Company against any liability asserted against or incurred by such person
in such capacity or arising out of such person's status as such, whether or
not the Company would have the power to indemnify him against such liability
under the provisions of this Article VIII.

8.7    CONFLICTS

       No indemnification or advance shall be made under this Article VIII,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any
circumstance where it appears:

              (1)    That it would be inconsistent with a provision of the
Memorandum, these Bye-Laws, a resolution of the Shareholders or an agreement
in effect at the time of the accrual of the alleged cause of the action
asserted in the proceeding in which the expenses were incurred or other
amounts were paid, which prohibits or otherwise limits indemnification; or

              (2)    That it would be inconsistent with any condition
expressly imposed by a court in approving a settlement.

                     ARTICLE IX -- BYE-LAWS

9.1    AMENDMENT

       Notwithstanding anything to the contrary contained herein, no Bye-Law
shall be rescinded, altered or amended and no new Bye-Law shall be made until
the same has been approved by a resolution by the Board and by the
affirmative vote at any general meeting of a sixty percent (60%) of all
outstanding shares entitled to vote, voting as a single class, or by such
greater majority as may be required by the Companies Act or these Bye-Laws.

9.2    APPROVAL BY CLASS

       A proposed amendment to these Bye-Laws must be approved by the
affirmative vote of a majority of the outstanding shares entitled to vote of
any class of stock, whether or not such class is entitled to vote thereon by
the provision of these Bye-Laws, if the amendment would:

       (a)    Increase or decrease the aggregate number of authorized shares
of such class, except that no such vote is required:

              (i)    For an amendment effecting only a stock split,
(including an increase in the authorized number of shares in proportion
thereto); or

              (ii)   For an amendment to increase the authorized shares of
any class to such number as will be sufficient from time to time, when added
to the previously authorized but unissued shares of such class, to satisfy
any option to purchase share or conversion right of securities convertible
into shares, if the Company had obtained the approval of the outstanding
shares of such class for the issue of such options or convertible securities.

                                      -26-

<PAGE>

       (b)    Effect an exchange, reclassification or cancellation of all
shares or part of the shares of such class, other than a stock split;

       (c)    Effect an exchange, or create a right of exchange of all or
part of the shares of another class into shares of such class;

       (e)    Cancel or otherwise affect dividends on the shares of such
class which have accrued but have not been paid.

       For the purposes of this Section 9.2, different series of the same
class of shares shall not constitute different classes for the purpose of
voting by classes except when a series is adversely affected by an amendment
in a different manner than other series of the same class.

       This Section 9.2 may only be amended by the affirmative vote of a
majority of the outstanding shares entitled to vote of each class and series
of stock of which shares are outstanding.

however, that, not more often than quarterly, Landlord may, by written notice
to Tenant, revise its estimate for such year, and subsequent payments by
Tenant for such year shall be based upon such revised estimate.

          (B)  Within ninety (90) days after the close of each calendar year
or as soon thereafter as is practicable, Landlord shall deliver to Tenant a
statement of that year's actual Property Taxes and Operating Expenses, as
determined and certified by Landlord (the "Landlord's Statement") and such
Landlord's Statement shall be binding upon Landlord and Tenant, except as
provided in Section 4.4 below. If the amount of the actual Tax and Operating
Expenses is more than the estimated payments for such calendar year made by
Tenant, Tenant shall pay the deficiency to Landlord upon receipt of
Landlord's Statement. If the amount of the actual Tax and Operating Expenses
is less than the estimated payments for such calendar year made by Tenant,
any excess shall be credited against Rent (as hereinafter defined) next
payable by Tenant under this Lease or, if the Lease Term has expired, any
excess shall be paid to Tenant. No delay in providing the statement described
in this subparagraph (B) shall act as a waiver of Landlord's right to payment
under Section 4.2.

          (C)  If this Lease shall terminate on a day other than the end of a
calendar year, the amount of the Tax and Operating Expense Adjustment to be paid
pursuant to Section 4.1 that is applicable to the calendar year in which such
termination occurs shall be prorated on the basis of the number of days from
January 1 of the calendar year to the termination date bears to 365. The
termination of this Lease shall not affect the obligations of Landlord and
Tenant pursuant to Section 4.2 to be performed after such termination.

     4.4  REVIEW OF LANDLORD'S STATEMENT.  Provided that Tenant is not then
in default under this Lease and provided further that Tenant strictly
complies with the provisions of this Section 4.4, Tenant shall have the
right, once each calendar year, to reasonably review supporting data for any
portion of a Landlord's Statement that Tenant claims is incorrect, in
accordance with the following procedure:


                                       7




<PAGE>

          (A) Tenant shall, within ten (10) business days after any such
Landlord's Statement is delivered, deliver a written notice to Landlord
specifying the portions of the Landlord's Statement that are claimed to be
incorrect, and Tenant shall simultaneously pay to Landlord all amounts due
from Tenant to Landlord as specified in the Landlord's Statement. Except as
expressly set forth in subsection (C) below, in no event shall Tenant be
entitled to withhold, deduct, or offset any monetary obligation of Tenant to
Landlord under the Lease (including without limitation, Tenant's obligation
to make all payments of Base Rent including the CPI Adjustment, if any, and
all payments of Tenant's Tax and Operating Expense Adjustment) pending the
completion of and regardless of the results of any review of records under
this paragraph. The right of Tenant under this paragraph may only be
exercised once for any Landlord's Statement, and if Tenant fails to meet any
of the above conditions as a prerequisite to the exercise of such right, the
right of Tenant under this paragraph for a particular Landlord's Statement
shall be deemed waived.

          (B) Tenant acknowledges that Landlord may maintain its records for
the Building at Landlord's office, Landlord's attorneys' offices or
Landlord's accountants offices and Tenant agrees that any review of records
under this section shall be at the sole expense of Tenant and shall be
conducted by an independent firm of certified public accountants of national
standing. Tenant acknowledges and agrees that any records reviewed under this
paragraph constitute confidential information of Landlord, which shall not be
disclosed to anyone other than the accountants performing the review and the
principals of Tenant who receive the results of the review. Tenant
acknowledges that Tenant shall not be entitled to review Landlord's financial
statements or tax returns or any leases, operating agreements, reciprocal
easement agreements or other agreements with tenants or occupants of the
Project. The disclosure of such information to any other person, whether or
not caused by the conduct of Tenant, shall constitute a material breach of
this Lease. Landlord, depending on the nature of Tenant's written notice, may
elect to make its records for the Building available to Tenant's accountants
at Landlord's office.

          (C) Any errors disclosed by the review shall be promptly corrected
by Landlord, provided, however, that if Landlord disagrees with any such
claimed errors. Landlord shall have the right to cause another review to be
made by an independent firm of certified public accountants of national
standing. In the event of a disagreement between the two accounting firms,
the review that discloses the least amount of deviation from the Landlord's
Statement shall be deemed to be correct. In the event that the results of the
review of records taking into account, if applicable, the results of any
additional review caused by Landlord reveal that Tenant has overpaid
obligations for a preceding period, the amount of such overpayment shall be
credited against Tenant's subsequent installment obligations to pay the
estimated Tax and Operating Expense Adjustment. In the event that such results
show that Tenant has underpaid its obligations for a preceding period, Tenant
shall be liable for Landlord's accounting fees, and the amount of such
underpayment shall be paid by Tenant to Landlord with the next succeeding
installment obligation of estimated Tax and Operating Expense Adjustment.

     4.5 PAYMENT. Concurrent with the execution hereof, Tenant shall pay
Landlord Base Rent for the first calendar month of the Term. Thereafter, Base
Rent described in Section 1.13, as adjusted as provided in Section 4.2, shall
be payable in advance on the first day of each calendar month, the prepaid Base
Rent for such partial month shall be prorated in the proportion that the
number of days this Lease is in effect during such partial month bears to the
total number of days in the calendar month. All prepaid Base Rent, and all
other amounts payable to Landlord by Tenant pursuant to the provisions of
this Lease, shall be paid to Landlord, without notice, demand, abatement,
deduction or offset, in lawful money of the United States at Landlord's
office in the Building or to such other person or at such other place as
Landlord may designate from time to time by written notice given to Tenant.
No payment by Tenant or receipt by Landlord of a lesser amount than the
correct Rent due hereunder shall be deemed to be other than a payment on
account; nor shall any endorsement or statement on any check or any letter
accompanying any check or payment be deemed to effect or evidence an accord
and satisfaction; and Landlord may accept such check or payment without
prejudice to Landlord's right to recover the balance or pursue any other
remedy in this Lease or at law or in equity provided.

                                       8

     4.6     LATE CHARGE; INTEREST.  Other remedies for non-payment of rent
notwithstanding, if any Monthly Base Rent payment or of additional rent is
not received by Landlord on or before the 10th day of the month next
following the month in which Tenant was invoiced, a late charge of ten
percent (10%) of such past due amount shall become due and payable in
addition to such amounts owed under this Lease.

     4.7     ADDITIONAL RENTAL.  For purposes of this Lease, all amounts
payable by Tenant to Landlord pursuant to this Lease, whether or not
denominated as such, shall constitute additional rental hereunder. Such
additional rental, together with the Base Rent and Rent Adjustments, shall
sometimes be referred to in this Lease as "Rent."

                                   ARTICLE 5

                               ADDITIONAL TAXES

     In addition to the Base Rent and other charges to be paid by Tenant
hereunder, Tenant shall reimburse Landlord upon demand for any and all taxes
payable by or imposed upon Landlord upon or with respect to: any fixtures or
personal property located in the Premises; any leasehold improvements made
in or to the Premises by or for Tenant; the Rent payable hereunder,
including, without limitation, any gross receipts tax, license fee or excise
tax levied by any governmental authority; the possession, leasing, operation,
management, maintenance, alteration, repair, use or occupancy of any portion
of the Premises (including without limitation any applicable possessory
interest taxes); or this transaction or any document to which Tenant is a
party creating or transferring an interest or an estate in the Premises.

                                   ARTICLE 6

                               SECURITY DEPOSIT

     Landlord and Tenant acknowledge and agree that Tenant has previously
deposited with Landlord the Security Deposit described in Section 1.16 above.
The Security Deposit is made by Tenant to secure the faithful performance of
all the terms, covenants and conditions of this Lease to be performed by
Tenant. If Tenant shall default with respect to any covenant of provision
hereof, Landlord may use, apply or retain all or any portion of the Security
Deposit to cure such default or to compensate Landlord for any loss or damage
which Landlord may suffer thereby. If Landlord so uses or applies all or any
portion of the Security Deposit, Tenant shall immediately upon written demand
deposit cash with Landlord in an amount sufficient to restore the Security
Deposit to the full amount hereinabove stated. Landlord shall not be required
to keep the Security Deposit separate from its general accounts and Tenant
shall not be entitled to interest on the Security Deposit. Within thirty (30)
days after the expiration of the Lease Term and the vacation of the Premises
by Tenant, the Security Deposit, or such part as has not been applied to cure
the default, shall be returned to Tenant.

                                   ARTICLE 7

                               USE OF PREMISES

     7.1     TENANT'S PERMITTED USE.  Tenant shall use the Premises only for
Tenant's Permitted Use as set forth in Section 1.16 above and shall not use
or permit the Premises to be used for any other purpose. Tenant shall, at its
sole cost and expense, obtain all governmental licenses and permits required
to allow Tenant to conduct Tenant's Permitted Use.

     7.2     COMPLIANCE WITH LAWS AND OTHER REQUIREMENTS.

             (A)     Tenant shall not use the Premises, or permit the
Premises to be used in any manner which: (a) violates any law, ordinance,
regulation or directive of any governmental authority having jurisdiction,
including without limitation any Certificate of Occupancy, or any covenant,
condition or restriction affecting the Building or the Premises; (b) causes
or is reasonably likely to cause damage to the Building or the Premises; (c)

or (g) violates the Rules and Regulations described in Article 20.

     (B) In addition to any other amounts payable by Tenant to Landlord
hereunder, Tenant shall pay to Landlord, as when billed by Landlord and as
additional rent, Tenant's Percentage Share of the cost of any improvements,
capital expenditures, repairs or replacements to the Building, or any
equipment or machinery used in connection with the Building, if any such item
is required under governmental laws, regulations, ordinances, or
interpretations thereof; however, any such costs that are properly charged to
a capital account shall not be payable in a single year but instead shall be
amortized over their useful lives, as determined by the Landlord in accordance
with generally accepted accounting practices, and only the annual
amortization amount (prorated based on the number of days of the Lease term
in the calendar year) shall be payable by Tenant with respect to any calendar
year.

     (C) COMPLIANCE WITH ADA REQUIREMENTS. Without limiting the generality
of the foregoing, Tenant shall promptly comply with all requirements of the
American with Disabilities Act and the regulations promulgated thereunder in
effect from time to time ("ADA Requirements").

          Tenant shall have exclusive responsibility for compliance with ADA
Requirements pertaining to the interior of the Premises, including for the
design and construction of the access thereto and egress therefrom. Landlord
shall have responsibility for compliance with ADA Requirements which affect
the common areas of the Building, subject to Tenant's obligations to pay for
its share of the expense of such compliance pursuant to Article 4 of this
Lease. Tenant shall comply promptly with any direction of any governmental
authority having jurisdiction which imposes any duty upon Tenant or Landlord
with respect to Premises or with respect to the use or occupation thereof,
and Tenant agrees to furnish Landlord with a copy of any such direction
promptly after receipt of the same. In addition, Tenant shall comply with
any reasonable plan adopted by Landlord which is designed to fulfill the
requirements of any Laws, including ADA Requirements.

          Should compliance by Tenant with this Paragraph require Landlord's
consent pursuant to Article 10, Tenant shall promptly seek such consent,
provide the assurances and documents required by said Article and, following
receipt of such consent, promptly comply with the provisions of such Article
and this Paragraph.

          If Tenant fails to comply as required in this Paragraph, after
notice to Tenant, Landlord may comply of cause compliance, in which case
Tenant shall reimburse Landlord upon demand for Landlord's costs incurred in
connection therewith.

     7.3  HAZARDOUS MATERIALS.

          (A) No Hazardous Materials, as defined herein, shall be Handled, as
also defined herein, upon, about, above or beneath the Premises or any
portion of the Project by or on behalf of Tenant, its subtenants or its
assignees, or their respective contractors, clients, officers, directors,
employees, agents, or invitees. Any such Hazardous Materials so Handled shall
be known as Tenant's Hazardous Materials. Notwithstanding the foregoing,
normal quantities of those Hazardous Materials customarily used in the
conduct of general administrative and executive office activities (e.g.,
copier fluids and cleaning supplies) may be used and stored at the Premises
without Landlord's prior written consent, but only in compliance with all
applicable Environmental Laws, as defined herein.

                                      10


<PAGE>

     (B) Notwithstanding the obligation of Tenant to indemnify Landlord
pursuant to this Lease, Tenant shall, at its sole cost and expense, promptly
take all actions required by any federal, state or local governmental agency
or political subdivision, or necessary for Landlord to make full economic
use of the Premises or any portion of the Project, which requirements or
necessity arises from the Handling of Tenant's Hazardous Materials upon,
about, above or beneath the Premises or any portion of the Project. Such
actions shall include, but not be limited to, the investigation of the
environmental condition of the Premises or any portion of the Building, the
preparation of any feasibility studies or reports and the performance of any
cleanup, remedial, removal or restoration work. Tenant shall take all actions
necessary to restore the Premises or any portion of the Building to the
condition existing prior to the introduction of Tenant's Hazardous Materials,
notwithstanding any less stringent standards or remediation allowable under
applicable Environmental Laws. Tenant shall nevertheless obtain Landlord's
written approval prior to undertaking any actions required by this Section,
which approval shall not be unreasonably withheld so long as such actions
would not potentially have a material adverse long-term or short-term effect
on the Premises or any portion of the Project.

     (C) "Environmental Laws" means and includes all now and hereafter
existing statutes, laws, ordinances, codes, regulations, rules, rulings,
orders, decrees, directives, policies and requirements by any federal, state
or local governmental authority regulating, relating to, or imposing
liability or standards of conduct concerning public health and safety or the
environment.

     (D) "Hazardous Materials" means: (a) any material or substance: (i)
which is defined or becomes defined as a "hazardous substance," "hazardous
waste," "infectious waste," "chemical mixture or substance," or "air
pollutant" under Environmental Laws; (ii) containing petroleum, crude oil or
any fraction thereof which is liquid at standard conditions of temperature
and pressure; (iii) containing polychlorinated biphenyls (PCB's); (iv)
containing asbestos; (v) which is radioactive, or (b) any other pollutant or
contaminant or hazardous, toxic, flammable or dangerous chemical, waste,
material or substance, as all such terms are used in their broadest sense,
and defined, regulated or become regulated by Environmental Laws, or which
cause a nuisance upon or waste to the Premises or any portion of the Building.

     (E) "Handle," "Handled," or "Handling" shall mean any installation,
handling, generation, storage, treatment, use, disposal, discharge, release,
manufacture, refinement, presence, migration, emission, abatement, removal,
transportation, or any other activity of any type in connection with or
involving Hazardous Materials.

                                   ARTICLE 8

                            UTILITIES AND SERVICES

     8.1 BUILDING SERVICES. As long as Tenant is not in default under this
Lease, Landlord agrees to furnish or cause to be furnished to the Premises
the following utilities and services, subject to the conditions and standards
set forth herein:

         (A) During Business Hours, non-attended automatic elevator service,
Monday through Friday.

         (B) During Business Hours, Monday through Friday, such air
conditioning, heating and ventilation as, in Landlord's judgment, are
required for the comfortable use and occupancy of the Premises; provided,
however, that if Tenant shall require heating, ventilation or air conditioning
in excess of that which Landlord shall be required to provide hereunder,
Landlord shall provide such heating, ventilation or air conditioning upon
Tenant's written request made at least three (3) hours before Tenant desires
to use heating, ventilation or air conditioning outside Business Hours on a
Monday through Friday and at least five (5) hours before the end of Business
Hours on the last week day that is not a holiday before Tenant desires to use
such heating, ventilation or air conditioning on a Saturday, Sunday or
holiday. Within ten (10) days of receiving an invoice therefor, Tenant shall
pay Landlord Landlord's established rates per hour, per Building for the use
of overtime heating, ventilation or air conditioning, which rates may be
adjusted from time to time, which rates shall reflect Landlord's actual cost
of providing such

                                       11


<PAGE>

utilities, with no profit to Landlord.

          (C)  At all reasonable times, electric current as required for
building standard lighting and fractional horsepower office machines;
provided, however, that: (i) without Landlord's consent, Tenant shall not
install, or permit the installation, in the Premises of any computers, word
processors, electronic data processing equipment or other type of equipment
or machines which will increase Tenant's use of electric current in excess of
that which Landlord is obligated to provide hereunder (provided, however,
that the foregoing shall not preclude the use of personal computers or
similar office equipment); (ii) if Tenant shall require electric current
which may disrupt the provision of electrical service to other tenants,
Landlord may condition its consent upon Tenant's payment of the cost of
installing and providing any additional facilities required to furnish such
excess power to the Premises and upon the installation in the Premises of
electric current meters to measure the amount of electric current consumed,
in which latter event Tenant shall pay for the cost of such meter(s) and the
cost of installation, maintenance and repair thereof, as well as for all
excess electric current consumed at the rates charged by the applicable local
public utility, plus a reasonable amount to cover the additional expenses
incurred by Landlord in keeping account of the electric current so consumed;
and (iii) if Tenant's increased electrical requirements will materially
affect the temperature level in the Premises or the Building, Landlord's
consent may be conditioned upon Tenant's requirement to pay such amounts as
will be incurred by Landlord to install and operate any machinery or
equipment necessary to restore the temperature level to that otherwise
required to be provided by Landlord, including but not limited to the cost of
modifications to the air conditioning system. Landlord shall not, in any way,
be liable or responsible to Tenant for any loss or damage or expense which
Tenant may incur or sustain if, for any reasons beyond Landlord's control,
either the quantity or character of electric service is changed or is no
longer available or suitable for Tenant's requirements. Tenant covenants that
at all times its use of electric current shall never exceed the capacity of
the feeders, risers or electrical installations of the Building. Landlord
shall provide at Landlord's cost no more than 5.0 Watts per useable square
foot of floor area of the Premises per Business Hour for both lighting and
power, and Landlord shall provide additional power to the Premises, as
needed, subject to the restrictions set forth above, at Tenant's sole cost
and expense pursuant to the provisions set forth below. A submeter on the
second floor Building 656 measures Tenant's electrical usage in a portion of
the Premises. The parties agree that Tenant's electrical usage each month per
Watt per useable square foot of floor area of the Premises per Business Hour
shall be deemed to be the total Watts used in the submetered portion of the
Premises during such month (as measured by the submeter) divided by the total
number of Business Hours during such month divided by the number of usable
square feet of floor area in the submetered portion of the Premises (the
"Actual Watts Used"). In the event the Actual Watts Used exceeds 5.0 Watts,
Tenant shall pay to Landlord each month within ten (10) days after receiving a
bill therefor the difference between the Actual Watts Used and 5.0 Watts
multiplied by the price charged per Watt per hour by the applicable local
electric utility used by Landlord in the Project multiplied by the number of
Business Hours in the applicable month multiplied by the total number of
usable square feet of floor area of the Premises. If submetering of
electricity in the Building will not be permitted under future laws or
regulations, the Rent will then be equitably and periodically adjusted to
include an additional payment to Landlord reflecting the cost to Landlord for
furnishing electricity to Tenant in the Premises.

          (D)  Water for drinking and rest room purposes.

          (E)  Reasonable janitorial and cleaning services, provided that the
Premises are used exclusively for office purposes and are kept reasonably in
order by Tenant. If the Premises are not used exclusively as offices, or if
the Tenant elects and Landlord consents, the Premises shall be kept clean and
in order by Tenant, at Tenant's expense, to the reasonable satisfaction of
Landlord and by persons approved by Landlord; and, in all events, Tenant
shall pay to Landlord the cost of removal of Tenant's refuse and rubbish, to
the extent that the same exceeds the refuse and rubbish attendant to normal
office usage.

     Any amounts which Tenant is required to pay to Landlord pursuant to this
Section 8.1 shall be payable upon demand by Landlord and shall constitute
additional rent.


                                      12



<PAGE>

     8.2 INTERRUPTION OF SERVICES. Landlord shall not be liable for any
failure to furnish, stoppage of, or interruption in furnishing any of the
services or utilities described in Section 8.1, and, in such event, Tenant
shall not be entitled to any damages nor shall any failure or interruption
abate or suspend Tenant's obligation to pay Base Rent and additional rent
required under this Lease or constitute or be construed as a constructive or
other eviction of Tenant. Further, in the event any governmental authority or
public utility promulgates or revises any law, ordinance, rule or regulation,
or issues mandatory controls or voluntary controls relating to the use or
conservation of energy, water, gas, light or electricity, the reduction of
automobile or other emissions, or the provision of any other utility or
service, Landlord may take any reasonably appropriate action to comply with
such law, ordinance, rule, regulation, mandatory control or voluntary
guideline without affecting Tenant's obligations hereunder. If utilities
provided by Landlord are interrupted for a period of more than three
consecutive days and such interruption is due to Landlord's fault or the
failure of equipment under Landlord's control, and if the Premises are
thereby rendered untenantable for the use intended, then during the period of
utility interruption, the Base Rental payable hereunder shall be abated, and
Tenant shall not be required to pay any charge for utilities provided by
Landlord.

                                    ARTICLE 9

                              MAINTENANCE AND REPAIRS

Building, lighting, HVAC, foundation, parking, Common Areas, the structural
soundness of the load bearing, exterior walls and exterior glass. In

Tenant's negligent or willful act or omission or an alteration to the
Premises made by Tenant. Notwithstanding anything to the contrary contained
herein. Landlord shall have no responsibility to maintain, repair or replace
any heating, ventilation and air conditioning units in the Premises
installed at any time by Tenant at Tenant's sole cost and expense ("Tenant's

for Landlord's obligations under this Section, it is intended by the parties
that Landlord shall have no obligation, in any manner whatsoever, to repair
and maintain the Premises, nor the Project, nor the equipment therein,
whether structural or non-structural, all of which obligations are intended
to be Tenant's obligations under this Lease. Tenant expressly waives the
benefit of any statute now or hereinafter in effect which would otherwise
afford Tenant the right to make repairs at Landlord's expense or to terminate
this Lease because of Landlord's failure to keep the Premises in good order,
condition and repair.

     9.2 TENANT REPAIRS. Tenant, at its own cost and expense, shall maintain
the Premises in a good condition (except for the items that are the
responsibility of Landlord under Section 9.1). Without limiting the
generality of the foregoing, Tenant shall maintain and keep in good repair

situated on or in the Premises or serving the Premises (as distinguished
from those serving the Property generally); and (e) those utility

further make all other repairs to the Premises made necessary by Tenant's
failure to comply with its obligations under this Section. All fixtures
installed by Tenant shall be new or shall have been completely and recently
reconditioned.

     9.3   REQUEST FOR REPAIRS.  All requests for repairs or maintenance that
are the responsibility of the Landlord pursuant to any provision of this
Lease must be made in writing to Landlord at the address in Section 1.8.

     9.4   TENANT DAMAGES.  Tenant, its agents, invitees or representatives
shall not cause any damage to be committed on any portion of the Premises or
Project, and at the expiration or earlier termination of this Lease, by lapse
of time or otherwise. Tenant shall deliver the Premises to Landlord in as
good condition as existed at the Commencement Date of this Lease, ordinary
wear and tear excepted. The cost and expense of any repairs necessary to
restore the condition of the Premises shall be borne by Tenant.
Notwithstanding anything to the contrary contained herein, Tenant shall leave
all electrical distribution systems, lighting fixtures, space heaters, air
conditioning, plumbing and other power systems upon the Premises in good
operating condition. In the event Tenant fails to perform Tenant's
obligations of repairs and maintenance under this Section, Landlord may at
its option, but shall not be required to, enter upon the Premises after ten
(10) days prior written notice to Tenant (except in case of an emergency, in
which case no notice shall be required), to perform such obligations on
Tenant's behalf and to place the Premises in good order, condition and
repair, and Tenant shall pay the cost thereof, together with any interest
thereon at the maximum rate allowed by law, as Additional Rent to Landlord.

     9.5   LANDLORD'S RIGHTS.  Landlord and its contractors shall have the
right, at all reasonable times, to enter upon the Premises to make any
repairs to the Premises or the Building reasonably required or deemed
reasonably necessary by Landlord and to erect such equipment, including
scaffolding, as is reasonably necessary to effect such repairs. Provided
Landlord shall first provide Tenant with 24 hours prior notification; except
when such notification is not required in cases involving and emergency
situation.

                                      ARTICLE 10

                         ALTERATIONS, ADDITIONS AND IMPROVEMENTS

     10.1  LANDLORD'S CONSENT; CONDITIONS.  Tenant shall not make or permit to
be made any alterations, additions, or improvements in or to the Premises
("Alterations") without the prior written consent of Landlord. Landlord may

Tenant's written notice of whether the Alterations include the Handling of
any Hazardous Materials, pursuant to Section 7.3; Tenant's delivery to
Landlord of such bonds and insurance as Landlord shall reasonably require;
and Tenant's payment to Landlord of all costs and expenses incurred by
Landlord because of Tenant's Alterations, including but not limited to costs
incurred in reviewing the plans and specifications for, and the progress of,
the Alterations.

     10.2  PERFORMANCE OF ALTERATIONS WORK.  All work relating to the
Alterations shall be performed in compliance with the plans and
specifications approved by Landlord, all applicable laws, ordinances, rules,
regulations and directives of all governmental authorities having
jurisdiction (including without limitation Title 24 of the California Code of
Regulations) and the requirements of all carriers of insurance on the
Premises and the Project, the Board of Underwriters, Fire Rating Bureau, or
similar organization. All work shall be performed in a diligent, first class
manner and so as not to unreasonably interfere with any other tenants or
occupants of the Project. All costs incurred by Landlord relating to the
Alterations shall be payable to Landlord by Tenant as additional rent upon
demand.

     10.3  LIENS.  Tenant shall pay when due all costs for work performed and
materials supplied to the Premises. Tenant shall keep Landlord, the Premises
and the Project free from all liens, stop notices and violation notices
relating to the Alterations or any other work performed


                                       14



<PAGE>

for, materials furnished to or obligations incurred by Tenant and Tenant
shall protect, indemnify, hold harmless and defend Landlord, the Premises and
the Project of and from any and all loss, cost, damage, liability and
expense, including attorneys' fees, arising out of or related to any such
liens or notices. Further, Tenant shall give Landlord not less than seven (7)
business days prior written notice before commencing any Alterations in or
about the Premises to permit Landlord to post appropriate notices of
non-responsibility. Tenant shall secure, at Tenant's sole expense, a
completion and payments bond satisfactory to Landlord for such work, and
during the progress of such work, Tenant shall, upon Landlord's request,
furnish Landlord with sworn contractor's statements and lien waivers covering
all work theretofore performed. Tenant shall satisfy or otherwise discharge
all liens, stop notices or other claims or encumbrances within ten (10) days
after Landlord notifies Tenant in writing that any such lien, stop notice,
claim or encumbrance has been filed. If Tenant fails to pay and remove such
lien, claim or encumbrance within such ten (10) days. Landlord, at its
election, may pay and satisfy the same and in such event the sums so paid by
Landlord, with interest from the date of payment at the rate set forth in
Section 4.6 hereof for amounts owed Landlord by Tenant shall be deemed to be
additional rent due and payable by Tenant at once without notice or demand.

     10.4  LEASE TERMINATION. Except as provided in this section, upon
expiration or termination of this Lease Tenant shall surrender the Premises
to Landlord in the same condition as when received, subject to reasonable
wear and tear. All Alterations (excluding Tenant's HVAC) shall become a part
of the Premises and shall become the property of Landlord upon the expiration
or earlier termination of this Lease, unless Landlord shall, by written
notice given to Tenant, require Tenant to remove some or all of Tenant's
Alterations, in which event Tenant shall promptly remove the designated
Alterations and shall promptly repair any resulting damage, all at Tenant's
sole expense. Notwithstanding the foregoing or anything to the contrary
contained herein, Tenant shall not be required to remove, at the expiration
or sooner termination of this Lease, any alterations made by Tenant to the
Premises prior to the Commencement Date of this Lease. All business and trade
fixtures, machinery and equipment, furniture, movable partitions and items of
personal property owned by Tenant or installed by Tenant at its expense in
the Premises including, but not limited to Tenant's HVAC, shall be and remain
the property of Tenant; upon the expiration or sooner termination of this
Lease, Tenant shall, at its sole expense, remove all such items and repair
any damage to the Premises or the Building caused by such removal. If Tenant
fails to remove any such items or repair such damage promptly after the
expiration or sooner termination of the Lease, Landlord may, but need not, do
so with no liability to Tenant, and Tenant shall pay Landlord the cost
thereof upon demand.

                                  ARTICLE II

                        INDEMNIFICATION AND INSURANCE

     11.1  INDEMNIFICATION. Tenant and Tenant's officers and directors agree
to protect, indemnify, hold harmless and defend Landlord and any mortgagee or
ground lessor, and each of their respective partners, directors, officers,
agents and employees, successors and assigns, regardless of any negligence
imputed to any indemnitee from and against:

           (A)  any and all loss, cost, damage, liability or expense as
incurred (including but not limited to attorneys' fees and legal costs)
arising out of or related to any claim, suit or judgment brought by or in
favor of any person or persons for damage, loss or expense due to but not
limited to, bodily injury, including death, or property damage sustained by
such person or persons which arises out of, is occasioned by or is in any way
attributable to the use or occupancy of the Premises or any portion of the
Project by Tenant or the acts or omissions of Tenant or its agents,
employees, contractors, clients, invitees or subtenants except that caused by
the sole gross negligence of Landlord or its agents or employees. Such loss
or damage shall include, but not be limited to, any injury or damage to, or
death of, Landlord's employees or agents or damage to the Premises or any
portion of the Project.

           (B)  any and all environmental damages which arise from: (i) the
Handling of any Tenant's Hazardous Materials, as defined pursuant to
Section 7.3 or (ii) the breach of any of the provisions of this Lease. For
the purpose of this Lease, "environmental damages" shall


                                      15



<PAGE>

mean (a) all claims, judgments, damages, penalties, fines, costs,
liabilities, and losses (including without limitation, diminution in the
value of the Premises or any portion of the Building, damages for the loss of
or restriction on use of rentable or usable space or of any amenity of the
Premises or any portion of the Building, and from any adverse impact of
Landlord's marketing of space); (b) all reasonable sums paid for settlement
of claims, attorneys' fees, consultants' fees and experts' fees; and (c) all
costs incurred by Landlord in connection with investigation or remediation
relating to the Handling of Tenant's Hazardous Materials, whether or not
required by Environmental Laws, necessary for Landlord to make full economic
use of the Premises or any portion of the Building, or otherwise required
under this Lease. To the extent that Landlord is strictly liable under any
Environmental Laws, Tenant's obligation to Landlord and the other
indemnities under the foregoing indemnification shall likewise be without
regard to fault on Tenant's part with respect to the violation of any
Environmental Law which results in liability to the indemnitee.  Tenant's
obligations and liabilities pursuant to this Section 11.1 shall survive the
expiration or earlier termination of this Lease.

          Tenant shall not be liable for any damage or liability of any kind
or for any injury to or death of persons arising in the Common Areas if
caused by or resulting from any negligent or willful act or omission of
Landlord or its employees or agents, and Landlords shall indemnify, defend,
protect and save Tenant harmless from all losses, costs, damages, claims and
liability whatsoever on account of any such damage or injury; provided,
however, that Landlord's obligation to indemnify and hold harmless Tenant
pursuant to the foregoing provisions is made for the purpose of providing any
benefit from time to time available to Tenant under policies of insurance
carried by Landlord, and further provided that the foregoing provisions shall
in no event require Landlord to provide any defense to Tenant or pay any sum
to or on behalf of Tenant in addition to that which may be provided and paid
pursuant to such policies of insurance as may be carried by Landlord from
time to time.

          Tenant shall not be liable for any damage or liability of any kind
for any and all environmental damages which arise from the Handling of any
Hazardous Materials, as defined pursuant to Section 7.3, by Landlord or its
employees or agents after the date of this Lease, and Landlord shall
indemnify, defend, protect and save Tenant harmless from all losses, costs,
damages, claims and liability whatsoever on account of any such damage.

     11.2 PROPERTY INSURANCE.

          (A)  At all times during the Lease Term, Tenant shall procure and
maintain, at its sole expense, "all-risk" property insurance, in an amount
not less than on hundred percent (100%) of the replacement cost covering (a)
all leasehold improvements in and to the Premises which are made at the
expense of Tenant; and (b) Tenant's trade fixtures, equipment and other
personal property from time to time situated in the Premises.  The proceeds
of such insurance shall be used for the repair or replacement of the property
so insured, except that if not so applied or if this Lease is terminated
following a casualty, the proceeds applicable to the leasehold improvements
shall be paid to Landlord and the proceeds applicable to Tenant's personal
property shall be paid to Tenant.

          (B)  At all times during the Lease Term, Tenant shall procure and
maintain business interruption insurance in such amount as will reimburse
Tenant for direct or indirect loss of earnings attributable to all perils
insured against in Section 11.2(A).

     11.3 LIABILITY INSURANCE.

          (A)  At all times during the Lease Term, Tenant shall procure and
maintain, at its sole expense, general liability insurance applying to the
use and occupancy of the Premises and the business operated by Tenant.  Such
insurance shall have a minimum combined single limit of liability of at least
$1,000,000 per occurrence and a general aggregate limit of $2,000,000.  All
such policies shall be written to apply to all bodily injury, property
damage, personal injury losses and shall be endorsed to include Landlord and
its agents, beneficiaries, partners, employees, and any deed of trust holder
or mortgagee of Landlord or any ground lessor as additional insureds.  Such
liability insurance shall be primary and not excess or contributing to any
other

                                       16



<PAGE>


insurance as may be available to the additional insureds.

          (B) Prior to the sale, storage, use or giving away of alcoholic
beverages on or from the Premises by Tenant or another person, Tenant, at its
own expense, shall obtain a policy or policies of insurance issued by a
responsible insurance company and in a form acceptable to Landlord saving
harmless and protecting Landlord and the Premises against any and all
damages, claims, liens, judgments, expenses and costs arising under any
present or future law, statute, or ordinance of the State of California or
other governmental authority having jurisdiction of the Premises, by reason
of any storage, sale, use or giving away of alcoholic beverages on or from
the Premises. Such policy or policies of insurance shall have a minimum
combined single limit of $2 million per occurrence and shall apply to bodily
injury, fatal or nonfatal; injury to means of support; and injury to property
of any person. Such policy or policies of insurance shall name the Landlord
and its agents, beneficiaries, partners, employees and any mortgagee of
Landlord or any ground lessor of Landlord as additional insureds.

     11.4 WORKERS' COMPENSATION INSURANCE. At all times during the Lease Term,
Tenant shall procure and maintain Workers' Compensation Insurance in
accordance with the laws of the State of California, and Employer's Liability
insurance with a limit not less than $1,000,000 Bodily Injury Each Accident;
$1,000,000 Bodily Injury By Disease -- Each Person; and $1,000,000 Bodily
Injury to Disease -- Policy Limit.

     11.5 POLICY REQUIREMENTS. All insurance required to be maintained by
Tenant shall be issued by insurance companies authorized to do insurance
business in the State of California and rated not less than A-VII in Best's
Insurance Guide. A certificate of insurance (or, at Landlord's option, copies
of the applicable policies) evidencing the insurance required under this
Article shall be delivered to Landlord not less than five (5) days prior to
the Commencement Date. No such policy shall be subject to cancellation or
modification without thirty (30) days prior written notice to Landlord and to
any deed of trust holder, mortgagee or ground lessor designated by Landlord
to Tenant. Tenant shall furnish Landlord with a replacement certificate with
respect to any insurance not less than thirty (30) days prior to the
expiration of the current policy. Tenant shall have the right to provide the
insurance required by this Article pursuant to blanket policies, but only if
such blanket policies expressly provide coverage to the Premises and the
Landlord as required by this Lease.

     11.6 WAIVER OF SUBROGATION. Notwithstanding anything to the contrary
contained in this Lease, Landlord and Tenant hereby waive any rights each may
have against the other, on account of any loss or damage occasioned to
Landlord or Tenant, as the case may be, or their respective property, the
Premises, its contents or to the other portions of the Project, arising from
any risk which is covered by the property insurance actually maintained by
the other party or, if not covered, which the other party is obligated to
insure or self-insure under this Lease; and the parties each, on behalf of
their respective insurance companies insuring the property of either Landlord
or Tenant against any such loss, waive any right of subrogation that it may
have against Landlord or Tenant, as the case may be without regard to the
negligence of the party being so released. The foregoing waivers of
subrogation shall be operative only so long as available in the State where
the Project is situated and provided further that no such policy is
invalidated thereby.

     11.7 FAILURE TO INSURE. If Tenant fails to maintain any insurance which
Tenant is required to maintain pursuant to this Article, Tenant shall be
liable to Landlord for any loss or cost resulting from such failure to
maintain. Landlord shall have the right, in its sole discretion, to procure
and maintain such insurance which Tenant is required to maintain hereunder
and the cost thereof shall be deemed additional rent due and payable by
Tenant. Tenant may not self-insure against any risks required to be covered
by insurance without Landlord's prior written consent.

                                   DAMAGE OR DESTRUCTION

    12.1 DAMAGE. In the event of a casualty to the Project, the following
shall apply:

    12.2 RECONSTRUCTION. If the Premises are damaged or destroyed during the
term by a casualty typically covered by "all-risk" insurance, Landlord shall,
to the extent that insurance proceeds are available therefor and are not
applied by any lender against payment of any existing loan on the Project,
except as hereinafter provided, diligently repair or rebuild them to
substantially the same condition in which they existed immediately prior to
such damage or destruction.

    12.3 RENT ABATEMENT. The Base Rent shall be abated from the date of the
damage or destruction in the same proportion that the rentable area of the
portion of the Premises which is unusable by Tenant bears to the total
rentable area of the Premises.

    12.4 EXCESSIVE DAMAGE OR DESTRUCTION. Notwithstanding whether the
Premises have been damaged or destroyed, if any of the Buildings are damaged
or destroyed to the extent that Landlord determines that they cannot, with
reasonable diligence, be fully repaired or restored by Landlord within ninety
(90) days after the date of the damage or destruction, Landlord may terminate
this Lease. Notwithstanding whether the Premises have been damaged or
destroyed, Landlord shall determine whether any of the Buildings damaged or
destroyed can be fully repaired or restored within the ninety (90) day
period, and Landlord's reasonable determination shall be binding upon Tenant.
Landlord shall notify Tenant of its determination, in writing, within forty
five (45) days after the date of the damage or destruction. If Landlord
reasonably determines that any of the Buildings damaged or destroyed can be
fully repaired or restored within the ninety (90) day period, this Lease
shall remain in force and effect and Landlord shall diligently repair and
restore the damage as soon as reasonably possible. If Landlord is required to
or elects to restore the Premises but Landlord reasonably estimates that such
restoration may require more than one hundred eighty (180) days, then Tenant
may terminate Lease upon written notice to Landlord given within fifteen (15)
days following Landlord's notice of the estimated time for restoration.

    12.5 UNINSURED CASUALTY. Notwithstanding anything contained herein to
the contrary, in the event of damage to or destruction of all or any portion
of the Buildings, which damage is not fully covered by the insurance policies
required hereinabove, Landlord may terminate this Lease by written notice to
Tenant, given within 45 days after the date of notice to Landlord that said
damage or destruction is not so covered.

    12.6 WAIVER. With respect to any destruction to which Landlord is
obligated to repair or may elect to repair under the terms of this Article,
Tenant hereby waives all rights to terminate this Lease pursuant to rights
otherwise presently or hereafter accorded by law to Tenant including, but not
limited to, Sections 1932 and 1933 of the California Civil Code.

    12.7 EXCEPTION TO LANDLORD'S OBLIGATIONS. Notwithstanding anything to the
contrary contained in this Article, Landlord shall have no obligation to
repair the Premises if either (a) the Building is so damaged as to require
repairs to the Building exceeding 20% of the full insurable value of the
Building; or (b) Landlord elects to demolish the Building; or (c) the damage
or destruction occurs less than one year prior to the Expiration Date,
exclusive of any option periods. Further, Tenant's rent shall not be abated
if either (i) the damage or destruction is repaired within five (5) business
days after Landlord receives written notice of Tenant of the casualty, or
(ii) Tenant, or any officers, partners, employees, agents or invitees of
Tenant, or any assignee or subtenant of Tenant is, in whole or in part,
responsible for the damage or destruction.

                                 CONDEMNATION

     13.1     TAKING. If the entire Premises or so much of the Premises as
to render the balance unusable by Tenant shall be taken by condemnation, sale
in lieu of condemnation or in any other manner for any public or quasi-public
purpose (collectively "Condemnation"), this Lease shall terminate on the date
that title or possession to the Premises is taken by the condemning authority,
whichever is earlier.

     13.2     AWARD. In the event of any Condemnation, the entire award for
such taking shall belong to Landlord, except that Tenant shall be entitled to
independently pursue a separate award relating to the loss of, or damage to,
Tenant's personal property and trade fixtures and Tenant's moving costs
directly associated with the taking.  Tenant shall have no claim against
Landlord or the award for the value of any unexpired term of this Lease or
otherwise.

     13.3     TEMPORARY TAKING. No temporary taking of the Premises shall
terminate this Lease or entitle Tenant to any abatement of the Rent payable
to Landlord under this Lease; provided, further, that any award for such
temporary taking shall belong to Tenant to the extent that the award applies
to any time period during the Lease Term and to Landlord to the extent that
the award applies to any time period outside the Lease Term.

                              LANDLORD'S OPTION

[Intentionally Omitted.]



                                  ARTICLE 15

                           ASSIGNMENT AND SUBLETTING

     15.1     RESTRICTION.  Without the prior written consent of Landlord
which consent shall not be unreasonably withheld or delayed, Tenant shall
not, either voluntarily or by operation of law, assign, encumber, or
otherwise transfer this Lease or any interest herein, or sublet the Premises
or any part thereof, or permit the Premises to be occupied by anyone other
than Tenant or Tenant's employees.  An assignment, subletting or other action
in violation of the foregoing shall be void and, at Landlord's option, shall
constitute a material breach of this Lease.  For purposes of this Section, an
assignment shall not include any transfer of any interest in this Lease or
the Premises by Tenant pursuant to a merger, division, consolidation,
liquidation or stock or asset sale, or pursuant to a change in ownership of
Tenant involving a transfer of voting control in Tenant (whether by transfer
of partnership or other beneficial, corporate stock or otherwise), unless
such transaction conflicts with the rights of other occupants of the Project.
Notwithstanding anything contained in this Article to the contrary, Tenant
expressly covenants and agrees not to enter into any lease, sublease,
license, concession or other agreement for use, occupancy or utilization of
the Premises which provides for rental or other payment for such use,
occupancy or utilization based in whole or in part on the net income or
profits derived by any person from the property leased, used, occupied or
utilized (other than an amount based on a fixed percentage or percentages of
receipts or sales), and that any such purported lease, sublease, license,
concession or other agreement shall be absolutely void and ineffective as a
conveyance of any right or interest in the possession, use, occupancy or
utilization of any part of the Premises.

     15.2     NOTICE TO LANDLORD.  If Tenant desires to assign this Lease or
any interest herein, or to sublet all or any part of the Premises, then at
least twenty (20) business days prior to the effective date of the proposed
assignment or subletting, Tenant shall submit to Landlord in connection with
Tenant's request for Landlord's consent:

              (A)     A statement containing (i) the name and address of the
proposed assignee or subtenant; (ii) such financial information with respect
to the proposed assignee or subtenant


                                       19

<PAGE>

as Landlord shall reasonably require; (iii) the type of use proposed for the
Premises; and (iv) all of the principal terms of the proposed assignment or
subletting; and

              (B)     Four (4) originals of the assignment or sublease on a
form approved by Landlord and four (4) originals of the Landlord's Consent to
Sublease or Assignment and Assumption of Lease and Consent.

     15.3     LANDLORD'S RECAPTURE RIGHTS. At any time within twenty (20)
business days after Landlord's receipt of all (but not less than all) of the
information and documents described in Section 15.2 above, Landlord may, at
its option by written notice to Tenant, elect to: (a) sublease the Premises or
the portion thereof proposed to be sublet by Tenant upon the same terms as
those offered to the proposed subtenant; (b) take an assignment of the Lease
upon the same terms as those offered to the proposed assignee; or (c)
terminate the Lease as to the portion of the Premises proposed to be assigned
or sublet, with a proportionate adjustment in the Rent payable hereunder if
the Lease is terminated as to less than all of the Premises or if more than
fifty percent (50%) of the Premises are proposed to be sublet or assigned,
then Landlord may terminate this Lease in its entirety.  If Landlord does not
exercise any of the options described in the preceding sentence, then, during
the above-described twenty (20) business day period, Landlord shall either
consent or deny its consent to the proposed assignment or subletting.

     15.4     LANDLORD'S CONSENT: STANDARDS.  Landlord's consent shall not be
unreasonably withheld; but, in addition to any other grounds for denial,
Landlord's consent shall be deemed reasonably withheld if, in Landlord's good
faith judgment: (i) the proposed assignee or subtenant does not have the
financial strength to perform its obligations under this Lease or any
proposed sublease; (ii) the business and operations of the proposed assignee
or subtenant are not of comparable quality to the business and operations
being conducted by other tenants in the Building; (iii) the proposed assignee
or subtenant intends to use any part of the Premises for a purpose not
permitted under this Lease; (iv) either the proposed assignee or subtenant,
or any person which directly or indirectly controls, is controlled by, or is
under common control with the proposed assignee or subtenant occupies space
in the Project, or is negotiating with Landlord to lease space in the
Project; (v) the proposed assignee or subtenant is disreputable; or (vi) the
use of the Premises by the proposed assignee or subtenant would, in
Landlord's reasonable judgment, significantly increase the pedestrian traffic
in and out of the Building or would require any alterations to the Project to
comply with applicable laws.

     15.5     ADDITIONAL RENT.  If Landlord consents to any such assignment
or subletting, all sums or other economic consideration received by Tenant in
connection with such assignment or subletting, whether denominated as rent or
otherwise, which exceeds, in the aggregate, the total sum which Tenant is
obligated to pay Landlord under this Lease (prorated to reflect obligations
allocable to less than all of the Premises under a sublease) after tenant
recovers all of its reasonable and customary costs associated with such
sublease, including but not limited to leasing commissions, attorney's fees
and tenant improvements for the sublessee, shall be paid to Landlord as
additional rent under the Lease without affecting or reducing any other
obligation of Tenant hereunder.

     15.6     LANDLORD'S COSTS.  If Tenant shall assign this Lease or shall
sublet all or any part of the Premises or shall request the consent of
Landlord to any assignment, subletting or other act, Tenant shall pay to
Landlord as additional rent Landlord's costs related thereto, including
Landlord's reasonable attorneys' fees.

     15.7     CONTINUING LIABILITY OF TENANT.  Notwithstanding any assignment
or sublease, Tenant shall remain as fully and primarily liable for the
payment of Rent and for the performance of all other obligations of Tenant
contained in this Lease to the same extent as if the assignment or sublease
had not occurred; provided, however, that any act or omission of any assignee
or subtenant, other than Landlord, that violates the terms of this Lease
shall be deemed a violation of this Lease by Tenant.

     15.8     NON-WAIVER.  The consent by Landlord to any assignment or
subletting shall not relieve Tenant, or any person claiming through or by
Tenant, of the obligation to obtain the


                                      20



<PAGE>

consent of Landlord, pursuant to this Article, to any further
assignment or subletting. In the event of an assignment or subletting,
Landlord may collect rent from the assignee or the subtenant without waiving
any rights hereunder and collection of the rent from a person other than
Tenant shall not be deemed a waiver of any of Landlord's rights under this
Article, an acceptance of assignee or subtenant as Tenant, or a release of
Tenant from the performance of Tenant's obligations under this Lease.


                             ARTICLE 16

                       DEFAULT AND REMEDIES

     16.1  EVENTS OF DEFAULT BY TENANT. The occurrence of any of the
following shall constitute a material default and breach of this Lease by
Tenant:

           (A)  The failure by Tenant to pay Base Rent or make any other
payment required to be made by Tenant hereunder within five (5) days after
written notice thereof by Landlord to Tenant.

           (B)  The abandonment of the Premises by Tenant or the vacation of
the Premises by Tenant for six (6) consecutive months (with or without the
payment of Rent).

           (C)  The failure by Tenant to observe or perform any other
provision of this Lease to be observed or performed by Tenant, other than
those described in Sections 16.1(A) and 16.1(B) above, if such failure
continues for ten (10) days after written notice thereof by Landlord to
Tenant: provided, however, that if the nature of the default is such that it
cannot be cured within the ten (10) day period, no default shall exist if
Tenant commences the curing of the default within the ten (10) day period and
thereafter diligently prosecutes the same to completion. The ten (10) day
notice described herein shall be in lieu of, and not in addition to, any
notice required under Section 1161 of the California Code of Civil Procedure
or any other law now or hereafter in effect requiring that notice of default
be given prior to the commencement of an unlawful detainer or other legal
proceeding.

           (D)  The making by Tenant of any general assignment for the
benefit of creditors, the filing by or against Tenant of a petition under any
federal or state bankruptcy or insolvency laws (unless, in the case of a
petition filed against Tenant, the same is dismissed within thirty (30) days
after filing); the appointment of a trustee or receiver to take possession of
substantially all of Tenant's assets at the Premises or Tenant's interest in
this Lease or the Premises, when possession is not restored to Tenant within
thirty (30) days; or the attachment, execution or other seizure of
substantially all of Tenant's assets located at the Premises or Tenant's
interest in this Lease or the Premises, if such seizure is not discharged
within thirty (30) days.

     16.2  LANDLORD'S RIGHT TO TERMINATE UPON TENANT DEFAULT.  In the event
of any default by Tenant as provided in Section 16.1 above, Landlord shall
have the right to terminate this Lease and recover possession of the Premises
by giving written notice to Tenant of Landlord's election to terminate this
Lease, in which event Landlord shall be entitled to receive from Tenant:

           (A)  The worth at the time of award of any unpaid Rent which had
been earned at the time of such termination; plus

           (B)  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 Tenant proves could have been
reasonably avoided; plus

           (C)  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 Tenant proves could be reasonably avoided;
plus

           (D)  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; and

           (E)  At Landlord's election, such other amounts in addition to or
in lieu of the foregoing as may be permitted from time to time by applicable
law.

     As used in subparagraphs (A) and (B) above, "worth at the time of award"
shall be computed by allowing interest at the rate of twelve percent (12%) per
annum, or such lower rate as shall be the then highest lawful rate. As used
in paragraph (C) above, "worth at the time of award" shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of
San Francisco at the time of award plus one percent (1%).

     16.3  LANDLORD'S RIGHT TO CONTINUE LEASE UPON TENANT DEFAULT. In the
event of a breach of this Lease and abandonment of the Premises by Tenant, if
Landlord does not elect to terminate this Lease as provided in Section 16.2
above, Landlord may from time to time, without terminating this Lease,
enforce all of its rights and remedies under this Lease. Without limiting the
foregoing, Landlord has the remedy described in California Civil Code Section
1951.4 (Landlord may continue this Lease in effect after Tenant's breach and
abandonment and recover Rent as it becomes due, if Tenant has the right to
sublet or assign, subject only to reasonable limitations). To the fullest
extent permitted by law, the proceeds of any reletting shall be applied
first to pay to Landlord all costs and expenses of such reletting (including
without limitation, costs and expenses of retaking or repossessing the
Premises, removing persons and property therefrom, securing new tenants,
including expenses for redecoration, alterations and other costs in
connection with preparing the Premises for new tenant, and if Landlord shall
maintain and operate the Premises, the costs thereof) and receivers' fees
incurred in connection with the appointment of and performance by a receiver
to protect the Premises and Landlord's interest under this Lease and any
necessary or reasonable alterations; second, to the payment of any
indebtedness of Tenant to Landlord other than Rent due and unpaid hereunder;
third, to the payment of Rent due and unpaid hereunder; and the residue, if
any, shall be held by Landlord and applied in payment of other or future
obligations of Tenant to Landlord as the same may become due and payable, and
Tenant shall not be entitled to receive any portion of such revenue.

     16.4  RIGHT OF LANDLORD TO PERFORM.  All covenants and agreements to be
performed by Tenant under this Lease shall be performed by Tenant at Tenant's
sole cost and expense. 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, Landlord may, but shall not
be obligated to, make any payment or after ten (10) days written notice and
opportunity to cure, except in the case of an emergency when no such notice
shall be required, perform any such other act on Tenant's part to be made or
performed, without waiving or releasing Tenant of its obligations under this
Lease. Any sums so paid by Landlord and all necessary incidental costs,
together with interest thereon at the lesser of the maximum rate permitted by
law, if any, or twelve percent (12%) per annum from the date of such payment,
shall be payable to Landlord as additional rent on demand and Landlord shall
have the same rights and remedies in the event of nonpayment as in the case
of default by Tenant in the payment of Rent.

     16.5  DEFAULT UNDER OTHER LEASES. If the term of any lease, other than
this Lease, heretofore or hereafter made by Tenant for any space in the
Project shall be terminated or terminable after the making of this Lease
because of any default by Tenant under such other lease, such fact shall
empower Landlord, at Landlord's sold option, to terminate this Lease by
notice to Tenant or to exercise any of the rights or remedies set forth in
Section 16.2.

     16.6  NON-WAIVER.  Nothing in this Article shall be deemed to affect
either parties rights to indemnification for liability or liabilities arising
prior to termination of this Lease for personal injury or property damages
under the indemnification clause or clauses contained in this Lease. No
acceptance by Landlord of a lesser sum than the Rent then due shall be deemed
to be other than on account of the earliest installment of such rent due, nor
shall any endorsement or statement on any check or any letter accompanying
any check or payment as rent be deemed an accord and satisfaction, and
Landlord may accept such check or payment without prejudice to Landlord's
right to recover the balance of such installment or pursue any other remedy
in the

                                       22

                  Lease provided. The delivery of keys to any employee of
                  Landlord or to Landlord's agent or any employee thereof shall
                  not operate as a termination of this Lease or a surrender of
                  the Premises.

                           16.7 CUMULATIVE REMEDIES. The specific remedies to
                  which either party may resort under the terms of the Lease are
                  cumulative and are not intended to be exclusive of any other
                  remedies or means of redress to which it may be lawfully
                  entitled in case of any breach or threatened breach by either
                  party of any provisions of the Lease. In addition to the other
                  remedies provided in the Lease, either party shall be entitled
                  to a restraint by injunction of the violation or attempted or
                  threatened violation of any of the covenants, conditions or
                  provisions of the Lease or to a decree compelling specific
                  performance of any such covenants, conditions or provisions.

                           16.8 DEFAULT BY LANDLORD. Landlord's failure to
                  perform or observe any of its obligations under this Lease
                  shall constitute a default by Landlord under this Lease only
                  if such failure shall continue for a period of thirty (30)
                  days (or the additional time, if any, that is reasonably
                  necessary promptly and diligently to cure the failure) after
                  Landlord receives written notice from Tenant specifying the
                  default. The notice shall give in reasonable detail the nature
                  and extent of the failure and shall identify the Lease
                  provision(s) containing the obligation(s). If Landlord shall
                  default in the performance of any of its obligations under
                  this Lease (after notice and opportunity to cure as provided
                  herein), Tenant may pursue any remedies available to it under
                  the law and this Lease.

                                ATTORNEYS' FEES: COSTS OF SUIT

                           17.1 ATTORNEYS' FEES. If either Landlord or Tenant
                  shall commence any action or other proceeding against the
                  other arising out of, or relating to, this Lease ar the
                  Premises, the prevailing party shall be entitled to recover
                  from the losing party, in addition to any other relief, its
                  actual attorneys fees irrespective of whether or not the
                  action or other proceeding is prosecuted to judgment and
                  irrespective of any court schedule of reasonable attorneys'
                  fees. In addition, Tenant shall reimburse Landlord, upon
                  demand, for all reasonable attorneys' fees incurred in
                  collecting Rent or otherwise seeking enforcement against
                  Tenant, its sublessees and assigns, of Tenant's obligations
                  under this Lease.

                           17.2 INDEMNIFICATION. Except to the extent set forth
                  in Section 11.1 above, should Landlord be made a party to any
                  litigation instituted by Tenant against a party other than
                  Landlord, or by a third party against Tenant, Tenant shall
                  indemnify, hold harmless and defend Landlord from any and all
                  loss, cost, liability, damage or expense incurred by Landlord,
                  including attorneys' fees, in connection with the litigation.

                                 SUBORDINATION AND ATTORNMENT

                           18.1 SUBORDINATION. This Lease, and the rights of
                  Tenant hereunder, are and shall be subordinate to the
                  interests of (i) all present and future ground leases and
                  master leases of all or any part of the Building; (ii) present
                  and future mortgages and deeds of trust encumbering all or any
                  part of the Building; (iii) all past and future advances made
                  under any such mortgages or deeds of trust; and (iv) all
                  renewals, modifications, replacements and extensions of any
                  such ground leases, master leases, mortgages and deeds of
                  trust; provided, however, that any lessor under any such
                  ground lease or master lease or any mortgagee or beneficiary
                  under any such mortgage or deed of trust shall have the right
                  to elect, by written notice given to Tenant, to have this
                  Lease made superior in whole or in part to any such ground
                  lease, master lease, mortgage or deed of trust. Upon demand,
                  Tenant shall execute, acknowledge and deliver any instruments
                  reasonably requested by Landlord or any such lessor, mortgagee
                  or beneficiary to effect the purposes of this Section 18.1.
                  Such instruments may contain, among other things, provisions
                  to the effect that such lessor, mortgagee or beneficiary
                  (hereafter, for the purposes of this Section 18.1, a
                  "Successor Landlord") shall (i) not be liable for any act or
                  omission of Landlord or its


                                       23
<PAGE>

                  predecessors, if any, prior to the date of such Successor
                  Landlord's succession to Landlord's interest under this Lease;
                  (ii) not be subject to any offsets or defenses which Tenant
                  might have been able to assert against Landlord or its
                  predecessors, if any, prior to the date of such Successor
                  Landlord's succession to Landlord's interest under this Lease;
                  (iii) not be liable for the return of any security deposit
                  under the Lease unless the same shall have actually been
                  deposited with such Successor Landlord; and (iv) be entitled
                  to receive notice of any Landlord default under this Lease
                  plus a reasonable opportunity to cure such default prior to
                  Tenant having any right or ability to terminate this Lease as
                  a result of such Landlord default. Notwithstanding anything to
                  the contrary contained this Lease, this Lease shall not be
                  subordinate to any hereafter placed mortgage, deed of trust or
                  lease, unless the holder thereof shall be willing to enter
                  into a non-disturbance agreement or subordination agreement
                  with Tenant on commercially reasonable terms pursuant to
                  which, so long as Tenant is not in default of any of Tenant's
                  obligations under this Lease after notice and expiration of
                  the applicable cure periods, Tenant's possession of the
                  Premises and its rights under this Lease shall not be
                  disturbed nor terminated as a result of any default by
                  Landlord under any mortgage, deed of trust or lease or as a
                  result of foreclosure or termination of such mortgage, deed of
                  trust or lease.

                           18.2 ATTORNMENT. If requested to do so, Tenant shall
                  attorn to and recognize as Tenant's landlord under this Lease
                  any superior lessor, superior mortgagee or other purchaser or
                  person taking title to the Building by reason of the
                  termination of any superior lease or the foreclosure of any
                  superior mortgage or deed of trust, and Tenant shall, upon
                  demand, execute any documents reasonably requested by any such
                  person to evidence the attornment described in this Section.

                           18.3 MORTGAGE AND GROUND LESSOR PROTECTION. Tenant
                  agrees to give any holder of any mortgage and any ground
                  lessor, by registered or certified mail, a copy of any notice
                  of default served upon the Landlord by Tenant, provided that
                  prior to such notice Tenant has been notified in writing (by
                  way of service on Tenant of a copy of Assignment of Rents and
                  Leases, or otherwise) of the address of such mortgage holder
                  or ground lessor (hereafter the "Notified Party"). Tenant
                  further agrees that if Landlord shall have failed to cure such
                  default within twenty (20) days after such notice to Landlord
                  (or if such default cannot be cured or corrected within that
                  time, then such additional time as may be necessary if
                  Landlord has commenced within such twenty (20) days and is
                  diligently pursuing the remedies or steps necessary to cure or
                  correct such default), then the Notified Party shall have an
                  additional thirty (30) days within which to cure or correct
                  such default (or if such default cannot be cured or corrected
                  within that time, then such additional time as may be
                  necessary if the Notified Party has commenced within such
                  thirty (30) days and is diligently pursuing the remedies or
                  steps necessary to cure or correct such default). Until the
                  time allowed, as aforesaid, for the Notified Party to cure
                  such default has expired without cure, Tenant shall have no
                  right to, and shall not, terminate this Lease on account of
                  Landlord's default.

                                       QUIET ENJOYMENT

                           Provided that Tenant performs all of its obligations
                  hereunder, Tenant shall have and peaceably enjoy the Premises
                  during the Lease Term, subject to all of the terms and
                  conditions contained in this Lease.

                  EXHIBIT B are hereby incorporated by reference herein and

                  observe and comply with the Rules and Regulations and any
                  reasonable and nondiscriminatory amendments, modifications
                  and/or additions thereto as may hereafter be adopted and
                  published by written notice to tenants by Landlord for the
                  safety, care, security, good order and/or cleanliness of
                  the Premises and/or Building. Landlord shall not be liable
                  to Tenant for any violation of such

                                       24

rules and regulations by any other tenant or occupant of the Building.

                        ESTOPPEL CERTIFICATES

     Tenant agrees at any time and from time to time upon not more than ten
(10) days' prior written notice from Landlord to execute, acknowledge and
deliver to Landlord a statement in writing addressed and certifying to
Landlord, or to the holder or assignee of any existing or prospective
mortgage encumbering the Building or any part thereof (hereafter a
"Mortgagee"), or to the lessor, or existing or prospective assignee of the
lessor's position, under any existing or prospective ground lease of the land
underlying the Project (hereafter a "Ground Lessor"), or to any prospective
purchaser of the land, improvements or both comprising the Project, that this
Lease is unmodified and in full force and effect (or if there have been
modifications, that the same is in full force and effect as modified and
stating the modifications); that Tenant has accepted possession of the
Premises, which are acceptable in all respects, and that any improvements
required by the terms of this Lease to be made by Landlord have been
completed to the satisfaction of Tenant; that Tenant is in full occupancy of
the Premises; that no rent has been paid more than 30 days in advance; that
the first month's Base Rent has been paid; that Tenant is entitled to no free
rent or other concessions except as stated in this Lease; that Tenant has not
been notified of any previous assignment of Landlord's or any predecessor
landlord's interest under this Lease; the dates to which Base Rent,
additional rent and other charges have been paid; that Tenant, as of the date
of such certificate, has no charge, lien or claim of setoff under this Lease
or otherwise against Base Rent, additional rent or other charges due or to
become due under this Lease; and that Landlord is not in default in
performance of any covenant, agreement or condition contained in this Lease
or any other matter relating to this Lease or the Premises or, if so,
specifying each such default. In addition, in the event that such certificate
is being given to any Mortgagee or Ground Lessor, such statement may contain
any other provisions customarily required by such Mortgagee or Ground Lessor
including, without limitation, an agreement on the part of Tenant to furnish
to such Mortgagee or Ground Lessor, as applicable, written notice of any
Landlord default and a reasonable opportunity for such Mortgagee or Ground
Lessor to cure such default prior to Tenant being able to terminate this
Lease. Any such statement delivered pursuant to this Section may be relied
upon by Landlord or any Mortgagee, Ground Lessor or prospective purchaser to
whom it is addressed and such statement, if required by its addressee, may so
specifically state. If Tenant does not execute, acknowledge and deliver to
Landlord the statement as and when required herein, Landlord is hereby
granted a power-of-attorney, coupled with an interest and irrevocable, to
execute such statement on Tenant's behalf, which statement shall be binding
on Tenant to the same extent as if executed by Tenant.

                         ENTRY BY LANDLORD

     Landlord may enter the Premises at all reasonable times to: inspect the
same; exhibit the same to prospective purchasers, lenders or tenants;
determine whether Tenant is complying with all of its obligations under this
Lease; supply janitorial and other services to be provided by Landlord to
Tenant under this Lease; post notices of non-responsibility; and make repairs
or improvements in or to the Building or the Premises; provided, however,
that all such work shall be done as promptly as reasonably possible and so as
to cause as little interference to Tenant as reasonably possible. Except to
the extent resulting from or relating to the negligence or willful misconduct
of Landlord, Tenant hereby waives any claim for damages for any injury or
inconvenience to, or interference with, Tenant's business, any loss of
occupancy or quiet enjoyment of the Premises or any other loss occasioned
by such entry. Landlord shall at all times have and retain a key with which
to unlock all of the doors in, on or about the Premises (excluding Tenant's
values, safes and similar areas designated by Tenant in writing in advance),
and Landlord shall have the right to use any and all means by which Landlord
may deem proper to open such doors to obtain entry to the Premises, and any
entry to the Premises obtained by Landlord by any such means, or otherwise,
shall not under any circumstances be deemed or construed to be a forcible or
unlawful entry into or a detainer of the Premises or an eviction,


                                       25
<PAGE>


actual or constructive, of Tenant from any part of the Premises. Such entry
by Landlord shall not act as a termination of Tenant's duties under this
Lease. If Landlord shall be required to obtain entry by means other than a
key provided by Tenant, the cost of such entry shall be payable by Tenant to
Landlord as additional rent.

                          TRANSFER OF LANDLORD'S INTEREST

       23.1 LANDLORD'S LEASE UNDERTAKING. Notwithstanding anything to the
contrary contained in this Lease or in any exhibits, Riders or addenda hereto
attached (collectively the "Lease Documents"), it is expressly understood and
agreed by and between the parties hereto that: (a) the recourse of Tenant or
its successors or assigns against Landlord with respect to the alleged breach
by or on the part of Landlord of any representation, warranty, covenant,
undertaking or agreement contained in any of the Lease Documents
(collectively, "Landlord's Lease Undertakings") shall extend only to
Landlord's interest in the real estate of which the Premises demised under
the Lease Documents are a part ("Landlord's Real Estate") and not to any other
assets of Landlord or its beneficiaries; and (b) except to the extent of
Landlord's interest in Landlord's Real Estate, no personal liability or
personal responsibility of any sort with respect to any of Landlord's Lease
Undertakings or any alleged breach thereof is assumed by, or shall at any
time be asserted or enforceable against, Landlord, the individual fee owners
of the Building, or against any of their respective directors, officers,
employees, agents, constituent partners, beneficiaries, trustees or
representatives.

       23.2 TRANSFER OF LANDLORD'S INTEREST. Landlord and each successor to
Landlord shall be fully released from the performance of Landlord's
obligations subsequent to their transfer of Landlord's interest in the
Building. Landlord shall not be liable for any obligation hereunder after a
transfer of its interest in the Building.

                                 HOLDOVER TENANCY

       If Tenant holds possession of the Premises after the expiration or
termination of the Lease Term, by lapse of time or otherwise, Tenant shall
become a tenant at sufferance upon all of the terms contained herein, expect
as to Lease Term and Rent. During such holdover period, Tenant shall pay to
Landlord a monthly rental equivalent to one hundred fifty percent (150%) of

provision found to be invalid shall be enforceable to the extent permitted by
law. The parties agree that in the event two different interpretations may be

that, upon execution of this Lease by Tenant and delivery to Landlord, such
execution and delivery by Tenant shall, in consideration of the time and
expense incurred by Landlord in reviewing the Lease and Tenant's credit,

forth herein (which offer to Lease shall be irrevocable for five (5) business

                                   ARTICLE 6

                    TECHNICAL ASSISTANCE AND TESTING SERVICES

6.1.      PRODUCTS TO BE TESTED, TESTING FACILITIES: interWAVE shall delvier
          to Nortel interWAVE Products, specified in a written product
          schedule, along with interWAVE-developed testing, interconnecting,
          or other equipment or items deemed necessary by Nortel and
          interWAVE ("Ancillary Equipment") to enable Nortel and interWAVE
          to perform Testing Services hereunder. interWAVE shall deliver the
          interWAVE Products and Ancillary Equipment to Nortel and Nortel
          shall use its best efforts to schedule the tests of the interWAVE
          Products in accordance with dates set forth in a written timetable
          schedule, provided (a) said product schedule and said timetable
          schedules are provided not less than ninety (90) days in advance of
          the times set forth for Testing; and (b) time is not of the essence
          with respect to the performance of Testing by Nortel. Notwithstanding
          interWAVE's failure to provide said ninety (90) days notice, Nortel
          will make good-faith efforts to perform Testing Services in
          accordance with the written schedules proposed. To facilitate
          Nortel's efforts to make its testing facilities available, interWAVE
          shall provide, on a quarterly basis, a written schedule showing new
          product release dates and projected testing facility needs for the
          following twelve months.

6.2       TECHNICAL REPRESENTATIVES: interWAVE and Nortel shall each supply
          to the other the name of a technical representative through whom
          all communications relating to the Testing shall be made
          (respectively "interWAVE's Technical Representative" and "Nortel's
          Technical Representative"). interWAVE's Technical Representative
          shall provide such assistance as Nortel may require in order to set
          up and adjust the interWAVE Products and Ancillary Equipment to
          enable Testing of the interWAVE Products to determine its
          inter-operability with Nortel's GSM Products. interWAVE's Technical
          Representative shall be informed of the time, location and identity
          of the Testing and shall attend the Testing and witness all aspect
          thereof. In the event interWAVE's Technical Representative or
          another interWAVE employee designated by interWAVE is unavailable
          or otherwise fails to attend, Nortel shall at its option either
          perform, postpone or cancel the Testing.

6.3       INFORMATION TO BE PROVIDED BY INTERWAVE: interWAVE shall supply to
          Nortel technical and operating descriptions of the interWAVE
          Products as may be required by Nortel to facilitate the performance
          of Testing Services, including, without limitation the following (to
          be hereinafter referred to as "interWAVE SUPPORT INFORMATION"):

          (a)       a general description of the interWAVE Products including

                    provide normal and appropriate input signals to the
                    interWAVE Products during the Testing;

<PAGE>

          (d)       a completed questionnaire, said questionnaire supplied by
                    Nortel at least two (2) weeks prior to the date the
                    Testing is scheduled to begin;

          (e)       any information derived by interWAVE from prior
                    certification tests involving the interWAVE Products or
                    from the operation of the interWAVE Products which would
                    relate to the Testing of the interWAVE Products; and

          Testing" and "Retesting". Nortel shall provide Testing Services
          (i.e., Initial Testing followed by Retesting) at a frequency of
          three (3) times per year. The duration of said Testing Services
          shall be not more than two weeks of Initial Testing and not more
          than one week of Retesting. As well, Nortel shall schedule an
          additional two (2) weeks of Initial Testing for the first Initial
          Testing period and an additional one (1) week of Initial Testing
          for the second Initial Testing period, and Nortel shall use
          reasonable efforts to accommodate interWAVE's schedule in connection
          therewith.

6.5.      INITIAL TESTING: The "INITIAL TESTING" shall consist of a test
          suite as Nortel and interWAVE jointly determine and specify in
          writing to be appropriate with respect to interWAVE Products. The
          Testing Services will be based upon the Support Information
          specified in Schedule A and the interWAVE Support Information. The
          Initial Testing shall determine the compliance of the interWAVE
          Products with the Specifications in Schedule A and the interWAVE
          Support Information. The Initial Testing will not determine the
          causes of any noncompliance with said Specifications and interWAVE
          Support Information.

6.6.      RETESTING: Upon receipt of a written request from interWAVE, and in
          accordance with a retesting schedule as shall be mutually agreed
          upon by the parties, Nortel shall provide interWAVE a subset of the
          above-referenced Initial Testing for the purpose of retesting
          ("RETESTING") any interWAVE Products which has been modified by
          interWAVE in order to correct issues which may have been discovered
          during Initial Testing; PROVIDED, however, that such access shall
          be provided to interWAVE only one time per Testing Services cycle,
          for a period not to exceed one week of time.

6.7.      ADDITIONAL TESTING: For Testing Services in excess of the stated
          frequency or duration of the Initial Testing and Retesting, Nortel
          may, at its option, following written notification to interWAVE,
          invoice interWAVE at Nortel's then-existing fully loaded costs (a
          schedule of Nortel's current fully loaded costs for Lab Services,
          which may be changed by Nortel from time to time in its sole
          discretion, is attached hereto as Schedule B). Nortel shall invoice
          interWAVE for such fees plus any taxes or like fees or charges
          which may be assessed against, or otherwise payable by, Nortel for
          Nortel's performance, except for any such tax, fee, or charge on
          Nortel's net income. interWAVE shall pay Nortel such fees within
          thirty (30) days of receipt of such invoice.

6.8.      COMMUNICATION AND DISCLOSURE OF RESULTS: Nortel shall promptly
          communicate the results of all Testing Services and any "Retesting"
          performed hereunder to interWAVE. interWAVE shall be entitled to
          disclose such results and the non-proprietary test methods,
          provided that interWAVE shall not include any reference to Nortel
          or include any information that would identify Nortel without
          Nortel's written consent. Nortel may, with interWAVE's written
          permission, provide such results to Nortel's customers, subject to
          such restrictions as the Parties deem to be appropriate regarding
          further disclosure by such customers of the results.

      subsystem ("BSS") testing. interWAVE shall be accorded three (3) days
      use of the Nortel MSC per calendar quarter, usages in excess of this
      amount to be provided at Nortel's then-existing fully loaded cost (see
      Schedule B for Nortel's current "MSC Access Cost"). When interWAVE
      requires access to the Nortel MSC, it shall advise Nortel at the earliest
      opportunity (providing not less than thirty (30) days notice) and Nortel
      shall use reasonable endeavors to make such facilities available at the
      requested times. Notwithstanding interWAVE's failure to provide said
      thirty (30) days notice, Nortel will make good-faith efforts to provide
      access at the requested times.

7.2.  GSM COMPONENT PURCHASES: To the extent of its legal right to do so,
      Nortel will use reasonable efforts to make available, through its
      existing GSM Component suppliers, the prices, terms and conditions
      associated with the provision of GSM Components for products of the
      type covered by the ORIGINAL EQUIPMENT MANUFACTURING (OEM) AGREEMENT
      executed concurrently herewith. interWAVE shall communicate to Nortel
      on a quarterly basis its projected 12-month forecast of requirements
      for such GSM Components so that these requirements can be
      incorporated by Nortel into its purchasing negotiations with its GSM
      Component suppliers. In the case where Nortel can obtain lower costs
      from an alternate GSM Component supplier for one or more GSM
      Components, interWAVE shall consider using said GSM Component
      supplier for the supply of said GSM Components.

7.3.  TEST BED: interWAVE shall develop a test bed at Redwood City,
      California to facilitate Nortel's testing of the hardware and
      software necessary to support the ORIGINAL EQUIPMENT MANUFACTURING
      (OEM) AGREEMENT and to facilitate such other purposes to which the
      parties have mutually agreed. The Test Bed shall meet the
      specifications attached hereto in Schedule C. interWAVE shall invoice
      Nortel for a fixed amount of $320,370.00U.S. according to the terms of
      Section 9.1.1 ("Price and Payment") of Schedule 1 of the ORIGINAL
      EQUIPMENT MANUFACTURING (OEM) AGREEMENT for the creation and ongoing
      maintenance of the Test Bed.

7.4.  ACCESS: The parties agree that, when Nortel is not utilizing the Test
      Bed, it may be utilized by interWAVE; therefore, access to and use of
      the Test Bed shall be governed by written schedule, said schedule to be
      maintained by interWAVE so as to avoid conflicting needs therefor, said
      schedule further maintained so as to give Nortel absolute priority of
      use on three (3) days notice and preferential priority of use on one
      (1) days notice.

        efforts to avoid or remove such causes of non-performance and shall
        proceed to perform with dispatch whenever such causes are removed or
        cease. In the event Nortel is unable to perform the Testing in
        accordance with Nortel's schedule as a result of any non-performance by
        interWAVE which is excused pursuant to this Section, Nortel shall be
        entitled to reschedule such Testing as Nortel determines to be
        appropriate.

                                     DURATION

14.1.   This Agreement shall commence on the date of its execution and
        terminate (save with the exception of the survivorship provisions)
        upon termination of the OEM Agreement, unless earlier terminated as
        hereinafter set forth, provided that upon termination, the parties
        agree to negotiate in good faith the extension of those portions of
        this Agreement relevant to interWAVE's ongoing support obligations
        to Nortel including any obligations arising under the ORIGINAL
        EQUIPMENT MANUFACTURING (OEM) AGREEMENT.

                                    TERMINATION

15.1.   BREACH: In the event either Party shall be in breach of, or fail to
        perform one or more of its material obligations under, this Agreement,
        the other Party may, by notice to the Party in default, require the
        remedy of the breach or the performance of the obligation and, if the
        Party so notified fails to remedy such breach or perform such
        obligation within ninety (90) days of the forwarding of a notice so to
        do, the other Party may, by notice, terminate this Agreement.

15.2.   UNENFORCEABILITY: In the event of an enforceable decision or
        directive declaring invalid an essential part of this Agreement,
        without which this Agreement would not have been entered into, this
        Agreement may, at the option of either Party, be terminated upon the
        giving of notice to the other Party.  Save as before set forth, in
        the event that any term, clause, provision or condition of this
        Agreement shall be similarly adjudged invalid for any reason
        whatsoever, such invalidity shall not affect the validity or
        operation of any other term, clause, provision or condition and such
        invalid term, clause, provision or condition shall be deemed to have
        been deleted from this Agreement.

15.3.   INSOLVENCY: In the event interWAVE commits any act of bankruptcy, or
        compounds with its creditors; or a petition or receiving order in
        bankruptcy is presented or made against interWAVE; or a petition for
        an administration order is presented in relation to interWAVE; or a
        resolution or petition to wind up interWAVE (other than for a legal
        reconstruction, reorganization or amalgamation) or a receiver or
        administrative receiver is appointed; and such act or petition is not
        cured, dismissed, or withdrawn within sixty (60) days thereafter; or
        interWAVE ceases to carry on business, Nortel may, without any delay,
        by notice, terminate this Agreement.  Any licenses and rights granted
        under this Agreement by interWAVE to and through Nortel are, for
        purposes of Section 365(n) of the U.S.  Bankruptcy Code, licenses of
        "intellectual property" within the meaning of Section 101 of the
        Bankruptcy Code.  Upon the commencement of a bankruptcy proceeding
        involving interWAVE, Nortel shall be entitled to retain and may fully
        exercise all rights and elections available under the Bankruptcy Code.

15.4.   GOVERNMENTAL APPROVALS:  In the event this Agreement does not receive
        all requisite approvals of any Government or governmental agency or
        officer within the period

      stipulated in Article 13 ('Registration") hereof, this Agreement may, at
      the option of either Party, be terminated upon notice to the other
      Party, but such termination shall not affect any undertakings of
      confidentiality or non-use provided in this Agreement.

15.5. PRODUCT SOFTWARE: Notwithstanding anything else contained herein, in
      the event this Agreement is terminated, each sublicensee of Product
      Software shall continue to have the right to use Product Software
      provided:

      (a)   such sublicensee is not in default under its written sublicense
            agreement with interWAVE; and

      (b)   such sublicense agreement is not inconsistent with the terms of
            this Agreement.

15.6. SURVIVAL: The provisions of Article 2 (Technical Information Grant),
      Article 4 (Software Grant), Article 8 ("Confidential Information")
      related to confidentiality and non-use, the provisions of Article 9
      ("Grant Back License"), the provisions of Article 10 ("Development
      Agreements"), and the provisions of Article 11 ("Liability") shall
      survive the termination of this Agreement.  Upon any termination of
      this Agreement, interWAVE shall, at Nortel's expense, ship the Test Bed
      to a location in the continental United States as designated by Nortel.

                                   ARTICLE 16

                               DISPUTE RESOLUTION

16.1. In the event the Parties are unable to amicably settle disputes between
      them, and unless the Parties mutually elect to pursue an alternative
      dispute procedure, whether binding or non-binding, all actions or
      proceedings to enforce, or which arise in connection with or relate to,
      this Agreement, any of the agreements in the form of Exhibits hereto or
      any of the transactions contemplated hereby or thereby shall be brought
      and litigated exclusively in the United States District Court, Northern
      District of California (or, in the event such court does not have
      jurisdiction, the courts of the State of California located in such
      district), unless such actions or proceedings are required to be
      brought in another court to obtain subject matter jurisdiction over the
      matter in controversy.  In any such actions or proceedings, service of
      process may be made upon the other Party hereto by registered or
      certified mail, return receipt requested, to its address indicated
      herein, which service shall be deemed effective 10 days after mailing.
      Each of the Parties hereto (i) consents to the jurisdiction of such
      court or courts and to service of process by registered or certified
      mail, as provided above, or by any other manner provided by the laws of
      the State of California and the rules of such courts and (ii) waives
      any right it may have to assert the doctrine of FORUM NON CONVENIENS,
      to assert that it is not subject to the jurisdiction of such courts or
      to object to venue to the extent any action or proceeding is brought in
      accordance with this sub-clause.

16.2  WAIVER OF TRIAL BY JURY. INTERWAVE AND NORTEL WAIVE THE RIGHT TO A
      TRIAL BY JURY IN ANY ACTION OR PROCEEDING UNDER THIS AGREEMENT OR ANY
      ACTION OR PROCEEDING ARISING OUT OF THE TRANSACTIONS CONTEMPLATED
      HEREBY, REGARDLESS OF WHICH PARTY INITIATES ANY SUCH ACTION OR
      PROCEEDING.

      changed at any time by giving fifteen (15) business days prior notice

17.3. BEST EFFORTS: In the event of a generally-prevailing labor dispute or
      other situation which will delay or impede the giving of notice by any

      and expeditious and least affected by such dispute or situation.

                                  ARTICLE 18
                                  ASSIGNMENT

18.1. ASSIGNMENT: This Agreement shall not be assigned or transferred by
      either Party, whether by way of merger, amalgamation, consolidation,
      reorganization, assignment, transfer, operation of law or otherwise,
      except with the written consent of the other or as otherwise provided
      pursuant to this Article.

18.2. Notwithstanding section 18.1, nothing herein shall prevent interWAVE
      from asssigning this Agreement, in its entirety, including all of its
      rights hereunder, to any person (the "Assignee"):

           (a) to whom interWAVE transfers substantially all of its assets; or

           (b) with whom interWAVE merges, amalgamates, consolidates or
               reorganizes and who thereby becomes the successor to the
               business of interWAVE;

      provided that:

           (a) if such Assignee is a Competitor of Nortel (as defined below)
               the provisions of section 18.4 below shall apply; and


                                                                Page 17 of 29
<PAGE>

              (b) the financial condition of such Assignee as of the date of
              such assignment shall be not substantially worse than the
              financial condition of interWAVE as of the Effective Date of
              this Agreement; and

              (c) such Assignee agrees in writing to Nortel (the
              "Acknowledgment") that it has assumed all obligations of
              interWAVE hereunder and shall be bound by the terms and
              conditions of this Agreement.

18.3.     For the purpose of this section a "Competitor of Nortel" means any
          person with whom Nortel competes and which has greater than two
          (2%) percent market share in the wireless telecommunications
          infrastructure products market.  Notwithstanding the foregoing, a
          person shall not be deemed to be a Competitor of Nortel simply by
          virtue of any competition arising solely from its acquisition of
          the business of interWAVE.  Nortel shall, from time to time, upon
          request from interWAVE, and in consultation with interWAVE, provide
          interWAVE with a current list of Competitors of Nortel and
          interWAVE shall be entitled to rely on such list for the purposes
          of section 18.2 until the later of: (i) one hundred and eighty
          (180) days from the date of issue by Nortel; or (ii) the date on
          which a new list is received by interWAVE.

18.4.     If the Assignee is a Competitor of Nortel, then within thirty (30)
          days of Nortel's receipt of the Acknowledgment, Nortel shall be
          entitled, at its option effective upon written notice to
          interWAVE, to terminate the following provisions of this Agreement
          (a "Partial Termination"): "Furnishing of Technical Information"
          (Article 5), "Technical Assistance and Testing Services" (Article
          6), "Mobile Switching Centre" (Section 7.1), GSM Component
          Purchases (Section 7.2), and "Access" (Section 7.4) and to
          terminate any Development Agreement made between the parties as
          contemplated by Article 10.  In the event:

          (a)     of a Partial Termination; or

          (b)     that this Agreement is terminated by interWAVE as a result
                  of a breach hereunder by Nortel; or,

          (c)     that this Agreement is terminated as a result of a breach
                  by Nortel under the OEM Agreement causing a termination of
                  the OEM Agreement; or

          (d)     that this Agreement is terminated by Nortel pursuant to the
                  provisions of section 15.2 hereof (Unenforceability),

Nortel shall refund to interWAVE, in either $US dollars or interWAVE shares
at Nortel's option, an amount calculated in accordance with the provisions of
Schedule D.  Notwithstanding the foregoing, Nortel shall pay the refund in
cash if the Fair Market Value (defined in accordance with the principles
articulated in Section 3.4(d)(iv)(d) of interWAVE's By-Laws) of one share of
interWAVE Series G Preferred Stock (a "Share") is less than six dollars and
six cents United States dollars ($U.S.6.06) per share.

18.5.     Notwithstanding section 18.1, this Agreement may be assigned by
          Nortel to any of its Subsidiaries or Affiliates upon notice to
          interWAVE.

18.6.     Notwithstanding any assignment, the Parties hereto shall remain
          liable for their respective obligations hereunder


                                                                 Page 18 of 29

                                  ARTICLE 19

                                    GENERAL

19.1.     GOVERNMENTAL APPROVALS:  The Parties recognize that the transfer of
          Technical Information and Development Software to foreign countries
          may be subject to the specific approval of the governments of said
          foreign countries, or various agencies thereof, and international
          control organizations in which that government participates, and
          that such governments or agencies may require further approval
          before the communication or transfer of any Technical Information
          or the sale of interWAVE Products and Developed Products is made to
          or for a country other than the U.S.A. Accordingly, interWAVE shall
          not sell or lease interWAVE Products and Developed Products or
          transfer or communicate Technical Information into any such
          countries without receiving such prior specific approval.

19.2.     PREEXISTING DUTIES:  Nothing in this Agreement shall be construed
          as requiring Nortel to disclose Technical Information, to grant
          rights under licenses, or to render any technical assistance, which
          would violate any confidentiality undertakings which it has towards
          third persons or which would violate any present or future law or
          decree of any government or governmental officer or agency, and
          nothing contained herein shall require the disclosure of Technical
          Information which would increase or impose any obligations on
          Nortel with respect to third parties.  In the event that Nortel
          determines that any disclosure by it hereunder would require the
          consent of any third party, Nortel agrees to use reasonable efforts
          to obtain the consent of such third party to the disclosure.

19.3.     EXCLUSIONS:  Nothing contained in this Agreement shall be construed
          as:

          (a)     requiring Nortel to file any patent application, to secure
                  any patent or other intellectual property right or to
                  maintain any patent or other intellectual property right in
                  force;

          (b)     constituting a warranty or representation by Nortel as to the
                  validity or scope of any patent or other intellectual
                  property right licensed hereunder;

          (c)     constituting a warranty or representation by Nortel that any
                  manufacture, use, lease, sale or sublicense by interWAVE
                  hereunder will be free from infringement of patents or other
                  intellectual property rights other than those under which,
                  and to the extent to which, licenses are granted hereunder;

          (d)     constituting an agreement to bring or prosecute actions or
                  suits against third parties for infringements;

          (e)     conferring any right to use, in advertising, publicity or
                  otherwise, any name, trade name or trademark, or any
                  contraction, abbreviation or simulation thereof; or

          (f)     conferring by implication, estoppel or otherwise upon
                  interWAVE any license or other right under any patent or
                  other intellectual property right, except the licenses and
                  rights expressly granted hereunder to interWAVE.

19.4.     AUTONOMY: Nothing contained in this Agreement shall limit in any
          manner Nortel's right to discontinue or change the design or
          characteristics of its products at any time without notice and
          without liability.


                                                                 Page 19 of 29
<PAGE>

19.5.     NOTICE OF BREACH:  The failure of either Party to give notice to
          the other Party of the breach or non-fulfillment of any term,
          clause, provision or condition of this Agreement shall not
          constitute a waiver thereof, nor shall the waiver of any breach or
          non-fulfillment of any term, clause, provision or condition of this
          Agreement constitute a waiver of any other breach or
          non-fulfillment of that or any other term, clause, provision or
          condition of this Agreement.

19.6.     INTEGRATION / ENTIRE AGREEMENT: This Agreement sets forth the entire
          agreement and understanding between the Parties with respect to
          Technical Information and interWAVE's use thereof, save for
          Development Agreements, and supersedes and cancels all previous
          negotiations, agreements, commitments and writings in respect to the
          subject matter hereof.  Neither Party hereto shall be bound by any
          term, clause, provision or condition save as expressly provided in
          this Agreement or as duly set forth on or subsequent to the date
          hereof in writing, signed by duly authorized officers of the Parties.

19.7.     INDEPENDENT PARTIES:  Nothing in this Agreement shall be construed
          as establishing or implying any partnership between the Parties
          hereto, and nothing in this Agreement shall be deemed to constitute
          either of the Parties hereto as the agent of the other Party or
          authorize either Party to incur any expenses on behalf of the other
          Party or to commit the other Party in any way whatsoever, without
          obtaining the other Party's prior written consent.

19.8.     CONFIDENTIALITY OF TERMS, PUBLICITY:  The existence of this
          Agreement, as well as its terms and conditions, shall be held in
          confidence by both Parties and only disclosed as may be agreed to
          by both Parties or as may be required to meet security disclosure
          or export permit requirements.  Neither Party shall make public
          statements or issue publicity or media releases with regard to this
          agreement or the relationship between the Parties without the prior
          written approval of the other Party.

19.9.     GOVERNING LAW:  This Agreement and all Purchase Orders shall be
          governed by the laws of the State of California, without
          application of conflict of law rules.  The Vienna International
          Convention for the Sale of Goods shall not apply.

          IN WITNESS WHEREOF, the Parties hereto have signed and executed
this Agreement on the date first above mentioned.

                  15.5.1    Class A Product Change

                           Class A Product Changes are changes required to
                           correct an Equipment deficiency (e.g., safety or fire
                           hazard, electrically or mechanically inoperative,
                           unsatisfactory operation, design defects, Equipment
                           does not operate as specified). If after at least 750
                           units of a board or equipment are in service, the
                           monthly board or equipment failure rate (Number of
                           board or equipment returned within a month/Total
                           Number of board or equipment in service), as

                           to make a change to only a limited number of a
                           particular type of Equipment. (This occurs when it is
                           necessary to correct a condition that occurs only in
                           certain Equipment combinations or with the use of
                           certain options). Such conditions shall be described
                           in the Product Change Notice.

                           the date of the notification of a Class A Product
                           Change, provide a schedule, acceptable to the
                           Purchaser for promptly implementing, at Supplier's

                  15.5.3    Class D Product Change

                           Class D Product Changes are design improvements,
                           component changes, or other minor improvements not
                           sufficiently significant as to require a Class B
                           classification. Class D Product Changes are also used
                           when a change is required to facilitate manufacture
                           or to effect a cost reduction not sufficiently
                           important to justify a Class B classification.

                           No Class D changes shall effect the interoperability
                           of the Equipment.

                  performance characteristics, and, (ii) shall process and
                  manipulate all date and time related functions correctly.
                  Without limiting the generality of the foregoing, all Software
                  shall:

                           -   correctly handle date and time related data
                               before, during and after January 1, 2000,

                               calculating, comparing and sequencing of dates
                               and times (in both forward and backward
                               operations spanning century boundaries).

         19.1     The Supplier shall indemnify and shall keep fully indemnified
                  the Purchaser against all actions, claims, proceedings,
                  damages, costs and expenses arising from any claim of
                  infringement, anywhere in the world, of any trade secret,
                  trademark, service mark, copyright, or patent arising solely
                  by reason of the Purchasers use, possession, re-sale, hire or
                  lease of Goods as provided by Supplier, as expressly
                  authorized in the Agreement. Notwithstanding the foregoing,
                  supplier assumes no liability for infringement claims related
                  to (i) the combination of Goods with other products not
                  provided by Supplier, if such infringement would have been
                  avoided by the use of such Goods alone, (ii) modification of
                  Goods after delivery by Supplier, or (iii) failure by
                  Purchaser, its employees, and agents after it becomes aware of
                  infringement to take all reasonable actions to prevent or
                  mitigate losses, damages, costs or expenses. Supplier shall
                  not be obligated to pay any liability, costs, or expenses
                  until finally adjudicated or settled without right of further
                  appeal.

         19.2     Supplier's obligation to indemnify Purchaser under this Clause
                  19 shall be subject to Purchaser providing Supplier: (i)
                  prompt notice of the claim giving rise to the indemnity, (ii)
                  sole control and authority regarding the defense and
                  settlement of such claim; and (iii) all information and
                  assistance reasonably requested the Supplier in connection
                  with the defense and/or settlement of such claim. The Parties
                  shall immediately on becoming aware notify the other promptly
                  in writing of any infringement or alleged infringement
                  referred to in 19.1.

         19.3     In the event of infringement as set forth in sub-clause 19.1,
                  the Supplier shall, at its own option and expense:

                  19.3.1   secure a license, the Supplier being responsible for
                           the payment of any and all royalty fees due or
                           becoming due, allowing the Purchaser use of the
                           infringing Goods and Services in and to exercise its
                           other rights granted under the Purchase Order and as
                           set out in the Agreement in respect of the Goods and
                           Services, provided that Purchaser agrees to cooperate
                           with Supplier and use all reasonable afforts to
                           assist Supplier; or

                  19.3.2   modify or replace the Goods and Services to avoid the
                           claim of infringement and any injunction or court
                           order, provided that such modification or replacement
                           does not affect materially performance of the Goods
                           and Services; or

                  19.3.3   if neither of the remedies in sub-clause 19.3.1 or
                           19.3.2 are reasonably practicable in Supplier's
                           reasonable judgement, Supplier may terminate this
                           Agreement and refund to Purchase the amounts paid for
                           the infringing Goods which cannot be used or sold due
                           to such infringement, depreciated on a five year
                           straight-line basis.

         19.4     The copyright and all other intellectual property rights in
                  all documents, drawings and information supplied by the
                  Purchaser in connection with this Purchase Order shall remain
                  vested in the Purchaser. Such documents, drawings and
                  information shall not be copied, disclosed or used except in
                  the performance of Supplier's obligations and exercise of its
                  rights pursuant to this Agreement and other agreements between
                  Supplier and Purchaser without the prior written consent of
                  the Purchaser.

         19.5     THE FOREGOING CLAUSE 19 STATES THE SOLE OBLIGATIONS OF
                  SUPPLIER AND THE SOLE AND EXCLUSIVE REMEDY OF PURCHASER FOR
                  ANY ACTUAL OR ALLEGED INTELLECTUAL PROPERTY INFRINGEMENT.

         19.6     EXCEPT FOR INDEMNIFICATION HEREUNDER FOR WILLFUL TRADE SECRET
                  MISAPPROPRIATION OR WILLFUL COPYRIGHT INFRINGEMENT, IN NO
                  EVENT SHALL SUPPLIER'S LIABILITY AND OBLIGATION UNDER THIS
                  CLAUSE 19 EXCEED THE NET AMOUNTS PAID BY PURCHASER TO SUPPLIER
                  FOR THE INFRINGING SYSTEMS GIVING RISE TO SUCH LIABILITY.

20.      INDEMNIFICATION AND INSURANCE

         20.1     Each party (the "Indemnifying Party") shall indemnify and save
                  harmless the other party (the "Indemnified Party") from any
                  liability or claim (including, without limitation, the costs
                  and reasonable attorney's fees in connection therewith) that
                  may be made by a third party for injury, including death, to
                  persons or damage to property arising directly out of the
                  Indemnifying Party's negligent acts or omissions in connection
                  with such Indemnifying Party's performance of its obligations
                  or exercise of its rights under this Agreement provided that
                  the indemnified Party has no contributory fault in connection
                  with such liability or claim.

         20.2     Without thereby limiting its responsibilities under the
                  Purchase Order Supplier shall maintain during its performance
                  under this Agreement General Liability Insurance, including
                  contractual, products liability and broad form vendors'
                  property damage endorsement with the limits of either
                  $5,000,000 combined single limit per occurrence for bodily
                  injury and property damage or $3,000,000 bodily injury per
                  occurrence and $2,000,000 property damage per occurrence.
                  Supplier must provide property insurance to cover all
                  consigned Purchaser material on Supplier's premises during the
                  term of the Agreement.

         20.3     The Supplier shall supply to the Purchaser written evidence
                  that such cover is in force for the required period. On
                  receipt of the Purchaser's request, the Supplier shall provide
                  evidence that such insurance is in force. Where the Supplier
                  cannot demonstrate, to the reasonable satisfaction of the
                  Purchaser the existence of adequate insurance, the Purchaser
                  shall have the right to effect such insurance as may be
                  necessary. The cost of such insurance shall be for the
                  Supplier's account.

21.      CONFIDENTIALITY

         The provisions of Clause 7 of the Agreement shall similarly apply to
         the Purchase Order(s).

22.      FORCE MAJEURE

         Except to obligations to pay money, (other than with respect to a
         Purchase Order which is itself subject to an event of force majeure
         declared by the Supplier), neither Party shall be liable for any breach
         of the Purchase Order owing to any of the following causes, or any
         similar causes, anywhere in the world, to the extent beyond its
         reasonable control: Act of God, fire, industrial action or lock-outs
         (except for industrial


                                 PAGE 25 OF 58

<PAGE>

         action or lock-outs by the Supplier's employees), the act or omission
         of Government, war, military operations or riot.

23.      PROPRIETARY NOTICES

         Purchaser agrees that all Goods and accompanying documentation shall
         include re-productions of the copyright notices and other proprietary
         legends of the supplier and its vendors. Purchaser shall not remove,
         efface or obscure any such notice or legends without approval of
         Supplier.

24.      RECOVERY OF SUMS DUE

         Whenever a sum of money due to one party from the other party, in
         relation to the Purchase Order or otherwise, is not paid by the due
         date, it may be deducted from any sum then due, or which at any time
         thereafter may become due to the other party under the Purchase Order
         or any other contract between the parties. Any sums due and not
         recovered by such deductions may be recovered as a debt.

25.      GENERAL

         25.1     The invalidity or unenforceability for any reason of any
                  provision of the Purchase Order shall not prejudice or affect
                  the validity or enforceability of its other provisions.

         25.2     The headings to these clauses are for reference only and shall
                  not affect their interpretation.

         25.3     Any notice to be given under the Purchase Order must be in
                  writing and may be delivered by hand or sent by prepaid post
                  to the "authorized representative" at the address given in
                  Schedule 7.

         25.4     No claim or right arising out of breach of the Purchase Order
                  by either party may be discharged in whole or in part by any
                  waiver or renunciation of the claim or right unless such
                  waiver or renunciation is in writing, signed by the other
                  party.

         25.5     Neither party may novate or assign this Purchase Order or any
                  of its rights benefits or obligations arising thereunder
                  without the prior written consent of the other party, except
                  that either party may assign and delegate all of its rights
                  and obligations hereunder in conjunction with a sale of all or
                  substantially all of its business or assets to which this
                  Purchase Order relates.

         25.6     The settlement of any dispute shall be done as per article 10
                  of the Agreement.

         25.7     Supplier represents that it has the rights which herein are
                  granted to Purchaser to sell the Goods for resale throughout
                  the world (subject to any applicable export control
                  restrictions), and that Supplier has taken appropriate action
                  with any of its existing distributors of similar goods to
                  remove any restrictions which would impede the granting of
                  these rights to Purchaser.

SCHEDULE 2

PRICES AND PRODUCT DESCRIPTION

1.       The prices detailed hereunder are firm and fixed for the calendar year
         in which this Agreement commenced (the "Initial Period"). Sixty (60)
         days prior to the expiration of the Initial Period, and each subsequent
         twelve (12) month period the Parties shall review and agree upon the
         prices that shall apply to Goods and Services for the next twelve (12)
         month period. The prices listed below include warranty during the
         Guarantee Period and technical support for 12 months.

         The prices listed below are subject to amendments according to the
clauses below:

         -        As for the BSC and the NSS, the prices are applicable only for
                  a period of three months following the Signature of this
                  Agreement As soon as the configurations and functions of the
                  BSC and NSS are clarified by the Supplier, the prices of the
                  BSC and of the NSS will be adjusted for price coherence
                  between the functions provided by the BSC and the NSS and
                  between this equipment and the NSS/BSC functions integrated in
                  the Combo. This adjustment should not impact the price of the
                  Combo nor the aggregate prices.

         -        In the event that the market prices have substantially
                  decreased, the Purchaser may request good faith efforts from
                  the Supplier to re-negotiate prices accordingly. Such price
                  reduction will become effective for all following deliveries
                  to the Purchaser.

         -        The Purchaser will discuss with the Supplier any single
                  opportunity for the Supplier's Goods that is greater than
                  twenty (20) million (U.S.) dollars. In the event that the
                  single opportunity pricing is granted to the Purchaser by the
                  Supplier, it will not impact the OEM pricing at that time.

         -        For each of the calendar years, the Purchaser and Supplier
                  will use their best efforts to agree upon and execute an
                  amendment to this Agreement that sets forth the prices and
                  volume discounts applicable for such a calendar year. The
                  Supplier guarantees a minimum of 5% decrease of price for the
                  Products from one calendar year to the next.

         -        The prices listed will be subject to a volume discount
                  according to the table below:

                  the quantity changed by ten percent up or down and each item
                  forecast as precisely as possible. Global bulk Purchase Orders

         4.3      The parties agree from time to time to discuss in good faith
                  whether the three (3) month fixed forecast period should be
                  reduced to conform with market requirements.

                  not met within 90 days of the target date in the Development
                  Plan.

         1.2      If the purchases by the Purchaser, during any quarter of 1998
                  or 1999 are less than those indicated in the Purchase Baseline
                  above, the Purchaser shall pay the Supplier, at the end of
                  such quarter sum equal to 38.1% of the Price of the shortfall
                  of Goods not purchased by the Purchaser ("Shortfall Payment").

                  1.2.1    To the extent that the Purchaser makes up the
                           shortfall with an excess in the following quarter
                           (over the purchase baseline for such following
                           quarter), the Supplier will credit the Purchaser for
                           the shortfall payment.

                  1.2.2    The Purchaser shall not be obligated to pay for any
                           shortfalls due to the Supplier's failure to deliver
                           Goods which meet mutually agreed acceptance criteria.

         2.       Reflecting the fact that the Purchaser will supply
                  substantial, valuable and proprietary technology, technical
                  information and know-how to the Supplier pursuant to the
                  Technical Information Agreement being entered into between the
                  Parties, the Supplier shall be restricted from entering into
                  an OEM or distributor agreement with Nokia or Ericsson until
                  December 31, 1999 ("Limited Exclusivity"). After such time,
                  the Purchaser's Limited Exclusivity shall be terminated only
                  if the annual purchase of Goods by the Purchaser is less than
                  eighty (80%) percent of the annual Purchase Baseline at the
                  end of any of the calendar years 2000, 2001, 2002. Nothing in
                  this Agreement shall be construed to prevent the Supplier from
                  developing other products, whether or not competing with the
                  Goods, for supply to Nokia or Ericsson or any other purchaser,
                  provided that the Supplier complies with all provisions of
                  this Agreement, the Technical Information Agreement and the
                  Patent License Agreement.

                  2.1      If, however, the Purchaser's failure to meet an
                           eighty (80%) percent annual target is attributable
                           solely to the Supplier's delay in meeting a material
                           microcellular product milestone, or the Supplier's
                           delay in delivering goods which meet mutually agreed

                  acceptance criteria, the annual period for determining
                  achievement of the annual target shall be extended for the
                  length of such delay

3.       On or before the Second Closing Date, the parties shall, by exercise of
         their commercially reasonable best efforts acting in good faith, agree
         upon a methodology for periodic reviews of the market forces, including
         pricing and other factors that are materially impacting the Purchaser's
         ability to achieve the commitments in the Purchaser's Purchase Baseline
         and related commitments hereunder and from time to time to negotiate in
         good faith any clarifications or modifications that may be appropriate
         and equitable in the interests of each of the parties by reasons of
         conditions prevailing from time to time in markets for the Goods.

         1.9.1    Notwithstanding Clause 1 above, the prices for individual
                  Purchase Orders once issued shall remain firm and fixed for
                  their duration, unless otherwise provided for by operation of
                  any other term of the Agreement.

         2.0      PRICING OF ENHANCEMENTS

                  2.1      Where the Supplier enhances the Goods above and
                           beyond the requirements of the relevant
                           Specification, including the new features or
                           facilities, the Supplier shall state in writing the
                           effect such enhancement will have on the Goods and
                           what adjustment, if any, will be required to the
                           Agreement. The Supplier shall furnish such details in
                           a time scale agreed between the Parties.

                  2.2      Where the Supplier shows that an enhancement involves
                           a change in the price or lead times for the Goods,

                           include any work that should be performed under any
                           other term of the Agreement or any Purchase Order.
                           This shall include, but not be restricted to,
                           enhancements in respect of operational support,
                           repair, build management and guarantee.

         3.0      FORECASTING MECHANISM FOR GOODS

                  3.1      DELIVERIES IN 1999. Prior to acceptance by the
                           supplier of any Orders issued by the purchaser, the
                           Parties shall review the Orders on a case by case
                           basis for 1999 to mutually agree upon the monthly
                           Delivery Dates. The monthly forecast(s) for 1999 for
                           Products provided to the supplier other than those
                           forecasts specified as Orders are for informational
                           purposes only. The purchaser further agrees to
                           provide the supplier with the shortfall between firm
                           Orders and monthly/quaterly/annual commitments to
                           purchase. In the second month of the quarter, the
                           Purchaser shall place orders to meet the commitment
                           for the quarter.


                                                                              8

                           ninth month of 1999, the purchaser shall provide to
                           the supplier, a twelve (12) month forecast of the
                           quantities of Products required and the Delivers
                           Dates within each month for such Products commencing
                           in the first month of 2000 (the "Forecast"). This
                           first twelve (12) month Forecast shall include any
                           deliveries for Orders accepted by the purchaser in
                           1999, and by mutual agreement at the time of the
                           Order having a Delivery Date in 2000. Thereafter the
                           purchaser shall provide to the supplier, prior to the
                           first day of each month, an adjusted twelve (12)
                           month rolling Forecast setting forth the Delivery
                           Dates within each month and the unit quantities of
                           Products for such Delivery Dates that the purchaser
                           expects it will Order from the supplier commencing in
                           the first month of 2000.

                  3.3      With respect to Products forecasted for which the
                           purchaser has not issued Orders, the purchaser may
                           adjust the Forecast from one Forecast to the next
                           within the following limitations:

                  3.4      The purchaser shall make Reasonable Efforts to ensure
                           that the adjustments to the Forecasts pursuant to
                           Article 3.3 shall be no more onerous than the
                           adjustments the purchaser must bear in the normal
                           course of the Purchaser's operations.

                  3.5      The purchaser shall ensure that there are sufficient
                           Orders placed with the supplier in advance of the
                           Delivery Date to provide for the delivery within the
                           Maximum Delivery Period of all of the Products which
                           the purchaser forecasted to be delivered during the
                           first month of each Forecast in accordance with
                           Article 3.3. Except as set forth above, the purchaser
                           shall not be obligated to issues Orders based on
                           Forecasts except as it supports minimum quarterly
                           contractual commitments. For the purposes of this
                           Article 3, the purchaser shall in the normal course
                           place Orders through a central purchaser order point.

                  3.6      The supplier shall accept any Order issued by the
                           purchaser for Products for delivery within the
                           Maximum Delivery Period to the extent such Products
                           were within the most recent Forecast. If the
                           purchaser orders Products in excess of the number of
                           units contained in the Forecast, the supplier and
                           purchaser shall mutually agree on the Delivery Dates
                           of such Orders, but the supplier shall use Reasonable
                           Efforts to ensure that the Delivery Date for Products
                           not Forecasted does not exceed sixty (60) consecutive
                           days. All deliveries of Orders shall be FOB the
                           Shipping Location.

                  3.7      The Purchaser, wherever possible will provide monthly
                           a rolling 12 month forecast, broken down by country,
                           of their requirements as precise as possible of the
                           Goods to the Supplier within forty-five days of
                           execution of this amendment. The Purchaser shall use
                           best efforts to forecast at least the amounts set
                           forth in the Purchase Baseline in Schedule 9. The
                           Supplier will give the Purchaser an overview of their
                           position with respect to supporting compliance into
                           the country's market.


                                                                              9

</TABLE>

         4.2      The Purchase Baseline can be adjusted, by good faith
                  negotiations, if any material microcellular product milestones
                  as defined in the Development Plan are not met within 90 days
                  of the target date stated in Schedule 10. It is further agreed
                  that if the Supplier is unable to deliver "support for EFR
                  Ready Hardware in Release 4.5" the purchase baseline for 1999
                  can be reduced by $1 million in each of quarters 3 and 4.
                  Also, if the agreed upon subset of MAP E is not delivered in
                  Release 5 NSS, then the purchase baseline for 2000 can be
                  reduced by $1.25 million per quarter. Furthermore, if the
                  Supplier is unable to meet GPRS, ISUP, and Freq. Hopping for
                  Release 6 the purchase baseline may be reduced by $5.0 million
                  in the second half of the year 2000. These reductions shall
                  not change the conditions in clause 4.3 below.
                  4.2.1    Both companies agree that they will work toward
                           defining and developing solutions to features (such
                           as tromboning ) that are required to meet market
                           opportunities.

         4.3      If the purchases by the Purchaser, during any quarter of 1999
                  or 2000 are less than those indicated in the Purchase Baseline
                  above, the Purchaser shall pay the Supplier, at the end of
                  such quarter, a sum equal to 38.1% of the Price of the
                  shortfall of Goods not purchased by the Purchaser ("Shortfall
                  Payment")

                  4.3.1    To the extent that the Purchaser makes up the
                           shortfall with excess in the following quarter (over
                           the purchase baseline for such following quarter),
                           the Supplier will credit the Purchaser for the
                           shortfall payment.

                  4.3.2    The Purchaser shall not be obligated to pay for any
                           shortfalls due to the Supplier's failure to deliver
                           Goods which meet mutually agreed acceptance criteria.

         4.4      Reflecting the fact that the Purchaser will supply
                  substantial, valuable and proprietary technology, technical
                  information and know-how to the Supplier pursuant to the
                  Technical Information Agreement being entered into between the
                  parties, the Supplier shall be restricted from entering into
                  an OEM or distributor agreement with Nokia or Ericsson until
                  December 31, 1999 ("Limited Exclusivity"). After such time,
                  the Purchaser's Limited Exclusivity shall be terminated only
                  if the annual purchase of Goods by the Purchaser is less than
                  eighty (80%) percent of $50 million, $70 million and $95
                  million at the end of any of the calendar years 2000, 2001, or
                  2002, respectively. The purchases by the Purchaser in excess
                  of $10 million in the year 1999 can be counted towards
                  fulfilling the requirement to purchase 80% of $50 million in
                  the year 2000 to retain the Limited Exclusivity. Any overage
                  in subsequent years will be applied on the same basis. Nothing
                  in this Agreement shall be construed to prevent the Supplier
                  from developing other products, whether or not competing with
                  the Goods, for supply to Nokia or Ericsson or any other
                  purchaser, provided that the Supplier complies with all
                  provisions of this Agreement, the Technical Information
                  Agreement and the Patent License Agreement.

                                                                             10

                  4.4.1    If. however, the Purchaser's failure to meet an
                           eighty (80%) percent annual target is attributable
                           solely to the Supplier's delay in meeting a material
                           microcellular product milestone, or the Supplier's
                           delay in delivering goods which meet mutually agreed
                           acceptance criteria, the annual period for
                           determining achievement of the annual target shall be

                  4.5.1    The Supplier warrants that it has obtained the
                           necessary approvals, including but not limited to GSM
                           11.21 certification, CE Mark, and interconnect. These
                           approvals allow the goods to be sold into many
                           countries. For the countries where the incremental
                           requirements are limited to "paper filings" and not
                           substantive testing and development, the Supplier
                           agrees to support entry into those countries.

                  4.5.2    The Supplier and Purchaser further agree that it will
                           put in place a mechanism by which the two parties can
                           address the requirements needed for the countries
                           where the Supplier currently does not meet all of the
                           requirements to enter the countries.

                  4.5.3    The Supplier and Purchaser agree to use the framework
                           below to identify and classify the countries.

                           4.5.3a   the products may be sold today without
                                    additional regulatory modifications;

                           4.5.3b   the product is being actively marketed, but
                                    where incremental regulatory activities may
                                    be required to sell;

                           4.5.3c   the Purchaser intends to market ultimately,
                                    and where incremental regulatory activities
                                    may be required to sell;

                           4.5.3d   The Purchaser does not plan to market the
                                    products or where the Seller or Purchaser is
                                    legally prohibited from selling the product.

                          INTERWAVE COMMUNICATIONS B.V.

                            PURCHASE/RESALE AGREEMENT

         This Agreement, effective as of February 27th, 1997, (the
"EFFECTIVE DATE"), is made by and between INTERWAVE Communications B.V., at
Emmaplein 5, 1075 AW Amsterdam, The Netherlands, with affiliated offices at
656 Bair Island Road, Suite 108, Redwood City CA 94063 ("INTERWAVE"), and
ADC Telecommunications, Inc., a Minnesota corporation with its principal
place of business at 4900 W. 78th St., Minneapolis, MN 55435 ("ADC").

                                    RECITALS

         Whereas, INTERWAVE develops, manufactures and distributes certain
wireless communications products, including the products set forth on
APPENDIX A hereto (the "Products"), and,

         INTERWAVE and ADC desire that ADC act as a non-exclusive reseller of
the Products under the terms and conditions set forth below,

                  NOW, therefore, INTERWAVE and ADC agree as follows:

     SECTION 1 AUTHORIZATION

                  (a) APPOINTMENT. Subject to the terms of this Agreement,
INTERWAVE appoints ADC, and ADC accepts such appointment, as a non-exclusive
reseller of the Products in and limited to the territory set forth in EXHIBIT
B (the "TERRITORY"). This Agreement applies only to those INTERWAVE products
which are listed in Appendix A as amended from time-to-time upon agreement
between the Parties and as herein provided.

                  (b) FORMAT. ADC may use or resell the Products as either
stand-alone products, or in combination with other products of ADC's choice
that meet the technical standards of the Products. INTERWAVE makes no
representation that the Products will be appropriate for combination with any
other product(s).

                  (c) NATURE OF AGREEMENT. To the extent that any Product
contains or consists of software, ADC's appointment only grants to ADC a
license to distribute and use such software Product as provided herein, and
does not transfer any right, title or interest to any such software Product
to ADC or ADC's customers. INTERWAVE will transfer title to Products to ADC
only to the extent that such Products consist of non-software items on the
terms specified herein. To the extent that such Products contain software,
such software (including firmware) will be licensed to ADC and its customers
on a right to use basis with all copyright, priority, or intellectual rights
remaining the property of INTERWAVE. Use of the terms "sell", "license",
"purchase", "license fees" and "price" will be interpreted in accordance with
this Section. INTERWAVE License Agreement is attached hereto as Exhibit F.

     SECTION 2 PRICE

         2.1 Prices for the INTERWAVE Products to be sold to ADC for resale
are based on market prices to end-users, and the discount schedule shown as
Appendix A to Exhibit "A" to this Agreement, as may be modified from time to
time. Initial ices are shown at Appendix B to Exhibit "A".

         2.2 Additional Products will be introduced by INTERWAVE from time to
time during the course of this Agreement and such products will be priced and
offered for resale by ADC through periodic amendments to Exhibit A.

     SECTION 3 AGREEMENT COMMENCEMENT DATE

         3.1 For purposes of timely execution of several of the terms and
conditions hereof, the "Agreement Commencement Date" shall be that date on
which ADC and INTERWAVE agree that (i) the initial INTERWAVE product has been

<PAGE>


independently certified to be GSM compliant, AND (ii) that the initial
INTERWAVE product meets the jointly agreed product specifications and
acceptance criteria. Such specifications and criteria shall be agreed to
prior to May 1, 1997. Such specifications and acceptance criteria shall be
based on INTERWAVE's "Release 1.1" feature set.

         SECTION 4 WARRANTY

         4.1 Limited Warranty. INTERWAVE MAKES NO WARRANTIES OR
REPRESENTATIONS AS TO PERFORMANCE OF PRODUCTS OR AS TO SERVICE TO ADC OR TO
ANY OTHER PERSON. EXCEPT AS SET FORTH IN INTERWAVE'S LIMITED WARRANTY
ATTACHED HERETO AS EXHIBITS E AND F, INTERWAVE MAY PROVIDE A DIFFERENT
WARRANTY ON NEW PRODUCTS OR SERVICES ADDED TO APPENDIX A.

supplied by ADC and incorporated into the Products, or the acts of ADC or
ADC's breach of this Agreement provided that such defects in such components
do not result from defects in the Products. In the event any claim covered by

provided reasonable cooperation and assistance in the defense thereof and the

action.

"Market Price" means: the end user price recorded by IWC and ADC for their
respective end-user (operator) sales accounts, by geographic region (Europe,
Asia-Pacific and North America.).

Average sales over the preceding three months will be used to determine the
"market" price.

Pricing will be reviewed and modified as necessary on a quarterly basis.. In
cases where special circumstances dictate a greater than normal discount from
list for an end-user (such as when an operator elects to make an equity
investment in conjunction with his product purchase arrangement) those
transactions will be excluded from the calculation of "average"; likewise if
ADC has a special case requiring an usual discount, then INTERWAVE will
cooperate and share the pain in terms of margin impact.

Depending on market price erosion over time, INTERWAVE and ADC reserves the
right to re-negotiate the ADC discount.

                             PRODUCT CHANGE NOTICES

INTERWAVE may, at any time, make changes to the Products or modify the
drawings and specifications relating thereto, or substitute Products of later
design to fill an order (hereinafter referred to as "Product Change"),
provided that any such Product Change, under normal and proper use, does not
affect form, fit or function of the Products or the interchangeability of the
Products with other Products, and that INTERWAVE notifies ADC in writing
thereof as soon as practicable. In the event any Product Change affects form,
fit or function of the Products, INTERWAVE shall notify ADC in writing
thereof prior to any planned change, except Class D Changes - non Customer
Affecting. In the event ADC may reject the planned change and so notifies
INTERWAVE within ten (10) days and INTERWAVE fails to reach agreement
thereon, ADC shall have the right to terminate any and all orders, in whole
or in part, for the Products affected by such change. Notwithstanding any
notice requirement above to the contrary, INTERWAVE shall immediately notify
ADC when it determines that a Class A Product Change (as defined hereinafter)
shall be made. INTERWAVE shall be authorized to make Class A Product changes
as soon as practical.

Notwithstanding any notice requirements to the contrary elsewhere in this
Agreement, all Class A Product Change Notices shall be provided, at no
charge, and forwarded in accordance with section titled "Notices". Product
Change Notices shall contain all the information set forth in Notices. If
INTERWAVE cancels a Product Change Notice, INTERWAVE must provide
notification in accordance with clause title "Notices" hereto and state the
reason for cancellation and what action, if any, is to be taken in locations
where the change may already have been implemented.

INTERWAVE shall determine the classification per the requirements of Bellcore
Technical Requirement Document TR-OPT-000209 of any proposed Product Change.
If ADC disagrees with any classification assigned by INTERWAVE, ADC shall
have the right to challenge such classification, and INTERWAVE shall, in good
faith, re-evaluate its classification. In the event that ADC and INTERWAVE
fail to reach agreement on any such classification, then ADC shall have the
right to terminate any or all Orders, in whole or in part, for Products
affected by such Product Change without penalty or obligation of any kind.

CLASS A PRODUCT CHANGE

Class A Product Changes are changes required to correct a Product deficiency
(e.g., safety or fire hazard, electrically or mechanically inoperative,
unsatisfactory operation, design defects. Product does not operate as
documented). Class A Product Changes require immediate action by INTERWAVE to
correct all affected Products, whether in the hands of INTERWAVE or ADC or
their customers including spare Products. In some cases, however, it may be
necessary to make a change to only a limited number of a particular type or
Product. (This occurs when it is necessary to correct a condition that occurs
only in certain Product combinations or with the use of certain options).
Such conditions shall be described in the Product Change Notice.

INTERWAVE shall, no later than thirty (30) days from the date of the
notification of a Class A Product Change, provide a schedule, acceptable to
ADC for promptly implementing, at INTERWAVE' expense, such changes with
respect to Products in ADC or their customer's possession. Such
implementation shall include the deinstallation, if necessary, of existing
Products and the engineering and installation of replacement or modified
Products or any additional materials.
<PAGE>


NOTICES

INTERWAVE shall furnish monthly status reports to ADC for all Class A Product
Changes of which INTERWAVE has notified ADC. This report shall contain the
following information:

         -        Product Change Notice Number
         -        Identity of the Products
         -        Model or part number and issue
         -        Date Product Change Notice issued
         -        Product ship date

                  ADC)
         -        Date completed, by location - Changes on hold at any location

CLASS B PRODUCT CHANGE

Class B Product Changes are changes made to incorporate improvements in
design resulting in better operation, improved testing, better maintenance,
longer life, service improvements, cost reductions, addition of essential
features, and the like.

All Products shipped to ADC after the effective date of any Class B Product
Change shall incorporate such change. Any Products shipped to ADC prior to
such date may be modified by ADC at its option and expense.

No Class B changes shall effect interoperability of the product

CLASS D PRODUCT CHANGE

Class D Product Changes are design improvements, component changes, new
features, or other minor improvements not sufficiently significant as to
require a Class B classification. Class D Product Changes are also used when
a change is required to facilitate manufacture or to effect a cost reduction
not sufficiently important to justify a Class B classification.

No Class D changes shall effect the interoperability of the product

INTERWAVE shall furnish in accordance with the "Notices" Section a quarterly
report listing all Product Change Notices released during the previous twelve
(12) months. This report will contain the following information: (a) Product

                          SUPPORT AND UPGRADE POLICY

1.   This policy describes the responsibilities of INTERWAVE and ADC with
     respect to hardware and software upgrades that are required to resolve
     demonstrated problems with the equipment. These are known as "problem
     fix upgrades". Hardware and software upgrades whose purpose is to
     enhance the functionality of the equipment ("feature upgrades") are
     quoted by INTERWAVE on a case-by-base basis and are not covered by this
     policy.

2.   For software problems that are reported by ADC, verified and/or
     recreated by INTERWAVE and which are fixed on a subsequent revision of
     software, INTERWAVE shall provide to ADC two (2) master copies of the
     software revision that incorporates the fix. The software will be
     accompanied by a completed "Engineering Change Request (Software)" form
     which, among other information, states the severity of the problem
     ("Class of Change") and a non-binding recommendation to ADC on the
     handling of the change in the field ("Field Effectivity Status"). The
     decision on the deployment, if any, of the software fix to one or more
     end-users in the field is the responsibility of ADC and all costs
     associated with that deployment will be borne entirely by ADC. This
     paragraph describes the totality of INTERWAVE' responsibilities which
     are limited to the provision of the two master sets of software and of
     the accompanying Engineering Change Request (ECR) notification.

3.   For hardware problems that are reported by ADC, verified and/or
     recreated by INTERWAVE and which are fixed by a hardware modification to
     the card, module or subsystem, INTERWAVE shall provide to ADC a
     completed "Engineering Change Request (Hardware)" form which, among
     other information, states the severity of the problem ("Class of
     Change"). The Class of Change defines INTERWAVE' responsibilities with
     regard to the performance of the hardware upgrade to units that are
     already installed in the field.

     a.  If the assigned Class of Change is "A", then INTERWAVE will perform
         the required hardware upgrade to effected units at no charge.
     b.  If the assigned Class of Change is "AC" or "AR", then INTERWAVE will
         perform the required hardware upgrade to effected units at no charge
         if ADC so requests in writing within thirty (30) days of receipt of
         the associated ECR.
     c.  If the assigned Class of Change is "B" or "D", then INTERWAVE will
         not upgrade any installed units at no charge. At ADC's request,
         INTERWAVE will quote such upgrades on a case-by-case basis.

     In all instances where the Class of Change obligates INTERWAVE to
     perform no-charge hardware upgrades. ADC shall request and receive a
     Return Authorization and shall promptly return all parts requiring the
     upgrade, freight prepaid to INTERWAVE' Service Department INTERWAVE
     shall have twenty (20) business days to perform the upgrade and return
     the part, freight prepaid, to ADC.

4.   For enhancements or new feature upgrades, ADC may send the Product to be
     upgraded freight prepaid to INTERWAVE' Service Department. ADC must
     issue a purchase order for the upgrade cost as specified in INTERWAVE'
     then current upgrade price list. A Return Authorization must be included
     with the Product sent to INTERWAVE. The upgraded Product will be
     returned to ADC within twenty (20) business days.

5.   Advance Replacement Service. If necessary, ADC may request an advance
     replacement exchange for the unit to be upgraded for those cases in
     which ADC can not wait the standard return period. ADC may arrange for
     this service as follows:
<PAGE>


                         -   Secure a Return Authorization for the Product to
                             be exchanged.

                         -   Issue a purchase order for the Product required
                             at INTERWAVE' then current list price plus the
                             cost of the upgrade and a $750 exchange service
                             fee.

                         -   Upon receipt of the proper purchase order.
                             INTERWAVE will ship to ADC an upgraded product
                             for exchange. Upon receipt of the Product ADC
                             should immediately return the exchanged Product
                             in the same container.

                         -   Upon receipt of the returned Product INTERWAVE
                             will issue a credit against ADCs purchase order
                             for the list price of the returned Product

If the exchanged Product is not returned within thirty (30) days ADC will be
invoiced for the Product shipped at the list price and ADC agrees to pay said
invoice due upon receipt
<PAGE>


                           CLASS OF CHANGE DEFINITIONS

CLASS A CHANGES

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

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

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

CLASS B - CHANGES

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

         a) Providing new features that directly affect Product operability.

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

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

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

CLASS D CHANGES- NON-CUSTOMER AFFECTING

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

         SECTION 1 AUTHORIZATION

                  (a) APPOINTMENT. Subject to the terms of this Agreement,
INTERWAVE appoints ADC, and ADC accepts such appointment, as a non-exclusive
reseller of the InterWave Products except for the territories as set forth in
EXHIBIT B (the "TERRITORY"). This Agreement applies only to those INTERWAVE
products which are listed in Appendix A as amended from time-to-time upon
agreement between the Parties and as herein provided. In addition, subject to
the terms of this Agreement, ADC appoints InterWave, and InterWave accepts such
appointment, as a non-exclusive reseller of certain ADC Products as identified
in Exhibit A for InterWave territories as set forth in EXHIBIT B (the
"TERRITORY").

                  (b) FORMAT. ADC and InterWave may use or resell the other
party's Products as either stand-alone products, or in combination with other
products of their choice that meet the technical standards of the Products. ADC
and INTERWAVE makes no representation that the other company's Products will be
appropriate for combination with any other product(s)."

Initial prices are shown at Appendix B to Exhibit "A". Prices for the ADC
Products sold by INTERWAVE are shown as Appendix C to Exhibit "A"; these ADC
products are to be sold by INTERWAVE according to the terms in Appendix C to
Exhibit A".

         2.2 Additional Products will be introduced by ADC and/or INTERWAVE from
time to time during the course of this Agreement and such products will be
priced and offered for resale by the other company through periodic amendments
to Exhibit A."

"Market Price" means: the end user price recorded by IWC and ADC for their
respective end-user (operator) sales accounts, by geographic region (Europe,
Asia-Pacific and North America.).

Average sales over the preceding three months will be used to determine the
"market" price.

Pricing will be reviewed and modified as necessary on a quarterly basis..

In cases where special circumstances dictate a greater than normal discount from
list for an end-user (such as when an operator elects to make an equity
investment in conjunction with his product purchase arrangement) those
transactions will be excluded from the calculation of "average"; likewise if ADC
has a special case requiring an usual discount, then INTERWAVE will cooperate
and share the pain in terms of margin impact.

Depending on market price erosion over time, INTERWAVE and ADC reserves the
right to re-negotiate the ADC discount.

Note:
1.       In conjunction with a commitment purchase agreement between ADC and
         INTERWAVE, ADC shall receive an additional [***] off of the
         discounted price for the first and second year of the purchase
         agreement. For example, the first year discount for purchases
         between $ 0 - 10 M is now [***] rather than [***].

                            APPENDIX E TO EXHIBIT "A"
                   PCS 1900 BSS HIGH LEVEL MARKET REQUIREMENTS

1.  GENERAL
The purpose of this paper is to define the high level market requirements for an
initial release of PCS 1900 BSS equipment. The PCS 1900 equipment (hardware and
software) shall in general have the same functionality as the corresponding DCS
1800 products at the same time. As such this paper describes only the
differences required for the PCS 1900 BSS products.

2.  1900 MHZ FREQUENCY BAND
The PCS 1900 BSS shall use the 1900 MHz frequency band, namely 1850 to 1910 MHz
for uplink, MS to BTS and 1930 to 1990 MHz for downlink, BTS to MS, channel
numbers 512 to 812 inclusive. All equipment shall operate over the full
frequency band and be compliant and tested to JTC PCS Air interface
Specification, PN3389.

The transmitter shall meet the FCC Code of Federal Regulations, volume 47,
section 24.238. titled - `emission limits' which defines the performance at the
band edge.

3.  TRANSCODING
The system shall support the GSM/JTC approved Enhanced Full Rate (EFR) vocoder
as well as the standard Full Rate (FR) vocoder. Both coders will be required to
operate for any TRX and TRAU timeslot at any time and shall allow handover from
FR to EFR and vice versa.

The design shall (if possible) enable a software upgrade to support another
speech coder at a later date.

Due to the T1 interface only supporting 24 64 kbit/s timeslots less DSP/TRAU
boards may be needed on the T1 board for the Abis interface at the BSC.

4.  T1 INTERFACE
The interface between BTS and BSC (Abis interface) and between BSC and MSC (A
interface) shall be 1.544 Mbit/s T1 format. This shall be compliant with ITU T
G.703, ANSI T1.403-1995 and all other appropriate standards.

The interface shall be configurable to support standard super frame (SF) or
extended super frame (ESF) formats, and shall use B8ZS line coding for 64 kbit/s
clear channel capability. The line build out shall be automatically set based on
the level received from the transmission network.

All the ESF CSU/DSU functions shall be supported. This includes local and remote
loopbacks and all performance measurement statistics.

Synchronization to the T1 incoming signal needs consideration due to the
extensive use of SONET networks for delivery of T1 services which may cause
disruptions after pointer alignment changes.

5.  A INTERFACE
The A interface signaling shall use ANSI based protocol stack (MTP and SCCP) for
connection of the BSC to a MSC.

Voice traffic on the A interface shall use mu-law encoding.

6.  3 DIGIT MNC
The PCS 1900 BSS shall support the use of both a 2 or 3 digit MNC.


                                      19

<PAGE>

7.  ENVIRONMENTAL
Full NEBS (GR 63) compliance will be required for any equipment that may be
placed in any of the AT+T or RBOC central office sites. Special attention should
be made to the burn, brush fire and seismic tests and lightning protection on T1
lines for all equipment and seismic tests for indoor equipment. The bullet
proofing is not required but any outdoor equipment should be tested to verify
what can be achieved.

Outdoor equipment shall meet TA-NWT-487 but for an operating ambient temperature
of -30 to +45 degC plus a solar load of 1120 W/sq.M..

All equipment shall also meet all national and other local standards in the
U.S. and Canada.

8.  OMC-R
All workstations shall use the US country kit.

The OMC-R server shall use a T1 interface (as per section 4) to a MSC or BSC for
communication with the BSS.

The OMC-R shall provide full support of all the above functionality changes.

9.  CRAFT
The craft interface shall provide full support of all the above changes.

10. QUALIFICATION
         -        FCC part 15, part 47 and part 68
         -        UL
         -        JTC, PN 3389
         -        Bellcore GR 63 NEBS, GR1089 and TA-NWT-487
         -        Health and safety
         -        CSA
         -        Environmental, EMC etc.

11.  LABELING
The equipment shall comply with all national and local labeling requirements in
the U.S. and Canada.

12. WAIVERS
The following are areas of waivers that may be acceptable if the fully compliant
solution is overly complex, expensive or will take too long to develop.

         - If the full band solution is overly complex or expensive to implement
         it may be acceptable to change this so that two versions of the RF
         distribution card in the Wavexpress exist creating a split band. The
         target frequency coverage for the two version shall be:

         High Band     Uplink - 1864 to 1910 MHz     Downlink- 1944 to 1990 MHz
         Low Band:     Uplink - 1850 to 1896 MHz     Downlink- 1930 to 1976 MHz

         - 2 TRX Wavexpress instead of 3 TRX?

Products; provided that: (i) each ADC customer executes an End-User License
Agreement containing terms at least as protective of the licensor as those
contained in Exhibit F attached hereto (the "End-User License"), provided that
INTERWAVE acknowledges that ADC may add to and or modify the terms of the
End-User License so long as the foregoing requirement is met; and (ii) INTERWAVE
is given a copy of the End-User License entered into with each ADC customer
promptly following its execution or any subsequent amendment thereto.

                  (h) ADC'S OBLIGATIONS. During the term of this Agreement ADC

                  MANDATORY TERMS OF END-USER LICENSE AGREEMENT

ADC hereby grants to Customer, and Customer hereby accepts from ADC, an
indefinite, non-exclusive and non-transferable right to use the software
described in Section 1 below (the "Software") on the hardware described in
Section 2 below (the "Hardware"), subject to the terms and conditions specified
below (the "License").

1.       SOFTWARE

"Software" means (i) the machine-readable object code version of the computer
programs described in the Product Schedule, whether embedded on disc, tape or
other media (the "Programs"); (ii) the user manuals and documentation for the
Programs that are provided to the Customer (the "Documentation"); (iii) the
fixes, customizations or revisions of the Programs or Documentation that are
provided to Customer (the "Enhancements"); and (iv) any copy of the Programs,
Documentation or Enhancements. Nothing in this License shall entitle Customer to
receive the source code of the Programs or Enhancements, in whole or in part.

2.       HARDWARE

"Hardware" means the hardware equipment configuration identified in the
Product Schedule on which the Software is first installed or for which it is
first provided. Customer may use the Programs and Enhancements only on the
Hardware while it possesses and operates the Hardware. Any other use or
transfer of the Programs or Enhancements requires ADC's prior approval, which
may be subject to additional charges.

3.       USE

Customer may use the Software only in and for Customer's own internal purposes
and business operations. Customer shall not permit any other person to use the
Software, whether on a timesharing, remote entry or other multiple user
arrangement. Customer may not copy any of the Documentation except for internal
use. Customer may copy the Programs and Enhancements solely for archival and
back-up purposes. Customer shall reproduce all confidentiality and proprietary
notices on each of these copies and maintain an accurate record of the location
of each copy the Programs or Enhancements. Customer may not otherwise copy,
translate, modify, adapt, decompile, disassemble or reverse engineer the
Software, except as and to the extent specifically permitted under applicable
law.

4.       CONFIDENTIALITY

Customer acknowledges that the Software embodies confidential and proprietary
information developed or acquired by or licensed to interWAVE Communications
International, B.V., a company organized under the laws of The Netherlands
("interWAVE"). Customer shall take all reasonable precautions necessary to
safeguard the confidentiality of the Software, including (i)


                                    -6-
<PAGE>

those taken by Customer to protect Customer's own confidential information and
(ii) those which ADC may reasonably request from time to time. Customer shall
not allow the removal or defacement of any confidentiality or proprietary notice
placed on the Software. If an unauthorized use or disclosure occurs, Customer
shall immediately notify ADC and take, at Customer's expense, all steps which
may be available to recover the Software and to prevent their subsequent
unauthorized use or dissemination. Customer shall have no confidentiality
obligation with respect to any portion of the Software that (i) Customer
independently developed before receiving the Software from ADC, (ii) Customer
lawfully obtained from a third party under no confidentiality obligation or
(iii) became available to the public other than as a result of an act or
omission by Customer or any of its employees or consultants.

5.       OWNERSHIP

All patents, copyrights, trademarks, service marks, trade secrets and other
proprietary rights in or related to the Software are and shall remain the
exclusive property of ADC or its licensors, whether or not specifically
recognized or perfected under local applicable law. Customer shall not take any
action that jeopardizes ADC's or its licensors' proprietary rights or acquire
any right in the Software, except the limited use rights specified in this
License. ADC or its licensors shall own all rights in any copy, translation,
modification or adaptation of, or derivative work based on, the Software.
Customer shall obtain, at ADC's request, the execution of any instrument that
may be appropriate to assign these rights to ADC or its licensors or perfect
these rights in ADC's or its licensor's name.

6.       INFRINGEMENT

If an action is brought against Customer claiming that the Software supplied by
ADC infringes a patent, copyright, trade secret or trade mark within the country
of installation (the "Territory"), ADC shall defend Customer, but only if: (i)
Customer notifies ADC promptly upon learning that the claim might be asserted;
(ii) ADC has sole control over the defense of the claim and any negotiation for
its settlement or compromise; and (iii) Customer takes no action that, in ADC's
reasonable judgment, is contrary to ADC's interest. If a claim described in this
Section may be or has been asserted, Customer shall permit ADC or its licensors,
at ADC's option, to: (i) procure the right to continue using the Software; (ii)
replace or modify the Software to eliminate the infringement while providing
functionally equivalent performance; or (iii) accept the return of the Software
and refund to Customer the amount actually paid to ADC for such Software, less
depreciation based on a 5-year straight-line depreciation schedule. ADC shall
have no indemnity obligation to Customer under this Section if the infringement
claim results from: (i) a correction or modification of the Software not
provided by ADC; (ii) the failure to promptly install an Enhancement; or (iii)
the combination of the Software with other items not provided by ADC.

7.       DISCLAIMER

Customer acknowledges that the warranties, conditions, guarantees or
representations granted with respect to the Software, if any, are or shall be
binding only on ADC. EXCEPT AS EXPRESSLY PROVIDED HEREIN, NEITHER ADC NOR ITS
LICENSORS GRANT

FITNESS FOR PARTICULAR PURPOSE. Any claim for breach of warranty, guarantee,
condition or representation, whether express or implied, may be brought solely
against ADC, except only as and to the extent otherwise specifically permitted
under applicable law, despite the foregoing disclaimer.

8.       EXCLUSION AND LIMITATION

UNDER NO CIRCUMSTANCES SHALL ADC OR ITS LICENSORS BE LIABLE FOR ANY
CONSEQUENTIAL, INDIRECT, SPECIAL, PUNITIVE OR INCIDENTAL DAMAGES OR LOST
PROFITS, WHETHER FORESEEABLE OR UNFORESEEABLE, BASED ON CUSTOMER'S CLAIMS OR
THOSE OF ITS CUSTOMERS (INCLUDING, BUT NOT LIMITED TO, CLAIMS FOR LOSS OF DATA,
GOODWILL, USE OF MONEY OR USE OF THE PRODUCTS, INTERRUPTION IN USE OR
AVAILABILITY OF DATA, STOPPAGE OF OTHER WORK OR IMPAIRMENT OF OTHER ASSETS),
ARISING OUT OF BREACH OR FAILURE OF EXPRESS OR IMPLIED WARRANTY, BREACH OF
CONTRACT, MISREPRESENTATION, NEGLIGENCE, STRICT LIABILITY IN TORT OR OTHERWISE.

FOR THE SPECIFIC ITEM THAT DIRECTLY CAUSED THE DAMAGE. THIS SECTION SHALL NOT
APPLY ONLY WHEN AND TO THE EXTENT THAT APPLICABLE LAW SPECIFICALLY REQUIRES
LIABILITY, DESPITE THE FOREGOING EXCLUSION AND LIMITATION.

9.       TERMINATION

ADC may terminate this License, upon reasonable notice and without judicial or
administrative resolution, if (i) Customer or any of its employees or
consultants breach any term or condition hereof, (ii) Customer permanently
discontinues the use of the Software, or (iii) Customer becomes insolvent or
enters into bankruptcy, suspension of payments, moratorium, reorganization or
any other proceeding that relates to insolvency or protection of creditors'
rights. Upon the termination of this License for any reason, all rights granted
to Customer hereunder shall cease, and Customer shall promptly: (i) purge the
Programs and Enhancements from the Hardware and all of Customer's other computer
systems, storage media and other files; (ii) destroy the Software and all copies
thereof; and (iii) deliver to ADC an affidavit which certifies that Customer
have complied with these termination obligations. The provisions of Sections 4,
5, 7, 8 and 10 shall survive the termination of this License.

Customer acknowledges that the Software and all related technical data are
subject to export controls under the U.S. Export Administration Regulations.
Customer may not re-export or disclose the Software or any related technical
data, or any direct product thereof, unless


                                    -8-
<PAGE>

Customer has obtained an appropriate authorization from ADC, its licensors and
the U.S. Commerce Department.

11.      INSPECTION

During the term of this License, ADC or its designees may, upon prior notice to
Customer, inspect the files, computer processors, equipment and facilities of
Customer during normal working hours to verify Customer's compliance with this
License. While conducting such inspection, ADC or its designees shall be
entitled to copy any item that Customer may possess in violation of this
License.

12.      BENEFICIARIES

The provisions of this License are intended to inure to the benefit of ADC, its
licensors and their related persons. If Customer breaches any of these
provisions, ADC and its licensors shall be entitled to enforce this License
directly against Customer, whether in ADC's or its licensors' own names.
Customer acknowledges that ADC executes the document setting forth this License
as principal on its own behalf and, exclusively to accept or otherwise perfect
its licensors' rights against Customer, as agent on behalf of such licensors.

13.      ASSIGNMENT

Customer shall not assign, delegate or otherwise transfer this License or any of
its rights or obligations hereunder, in whole or in part, without ADC's prior
approval. ADC may in its sole discretion assign, delegate or otherwise transfer

of competent jurisdiction any interim or provisional relief that may be
necessary to protect the rights or property of that party, pending the
establishment of the arbitral tribunal or pending the arbitral tribunal's
determination of the merits of the controversy.

15.      MISCELLANEOUS

Any waiver or modification of this License shall not be effective unless
executed in writing and signed by ADC. This License shall bind Customer's
successors-in-interest. If any provision of this License is held to be
unenforceable, in whole or in part, such holding shall not affect the validity
of the other provisions of this License, unless ADC in good faith deems the
unenforceable provision to be essential, in which case ADC may terminate this
License effective immediately upon notice to Customer. No failure or delay on
the part of ADC to exercise any right or remedy specified herein shall be
construed as a waiver of such right or remedy. This License constitutes the
complete and entire statement of all conditions and representations with respect
to its subject matter and supersedes all prior writings or understandings.

2.4    The limitations on the scope of the license and rights granted hereunder
       arising from the definitions of "Microcellular Infrastructure Products"
       and "Microcellular Public Radio Systems" (the "Definitions") are intended
       by the Parties to distinguish microcellular wireless infrastructure
       products from other wireless products and to reflect the capacities and
       specifications of the Microcellular Infrastructure Products making up the
       interWAVE product line at the Effective Date. The Definitions shall be
       subject to review by the Parties on a yearly basis from the Effective
       Date. The Parties agree to negotiate in good faith with a view to
       revising the scope of the Definitions to reflect the evolution of the
       microcellular infrastructure technology and the demands of the
       microcellular infrastructure marketplace. In any event, the scope of the
       license shall include at a minimum the products Nortel will source under
       the OEM Agreement and any products planned in the development agreements
       arising under the Technical Information Agreement. Where there is written
       agreement among the Parties, the agreed upon revised Definitions shall
       replace the current definitions for the purposes of the license granted
       hereunder. Notwithstanding the above, in the event that a significant
       technology change has impacted the microcellular infrastructure market,
       either party may request the other party on 60 days notice to meet and
       vary the Definitions based on this change. The Parties agree to negotiate
       this required definition change in good faith.

2.5   interWAVE shall have no right to grant sublicenses under the above
      licenses, but such limitation shall not be construed as limiting
      interWAVE's rights to directly and indirectly distribute, and allow
      its customers and transferees to use, Microcellular Infrastructure
      Products for their intended purposes. Such licenses also include the
      right to have Microcellular Infrastructure Products made by another
      manufacturer for the use, lease or sale by interWAVE, but only when
      of both the following conditions are met:

       (a)    the designs, specifications and working drawings for the
              manufacture of said Licensed Products are furnished by
              interWAVE; and

       (b)    said designs, specifications and working drawings are in
              sufficient detail that no material modification by the
              manufacturer is required other than adaptation to the
              production processes and standards normally used by the
              manufacturer which changes the characteristics of the
              products only to a negligible extent.

2.6   Nortel and NMC hereby release interWAVE, and all purchasers and users
      of Microcellular Infrastructure Products, from all claims, demands and
      rights of action which Nortel or NMC may have on account of any
      infringement or any alleged infringement of any of the patents licensed
      in this Section 2 by reason of the manufacture, use, lease or sale of
      Microcellular Infrastructure Products prior to the Effective Date by
      interWAVE.

3     TERM OF LICENSE

3.1   Subject to the terms and conditions of this Agreement, all patent
      licenses herein granted shall commence on the Effective Date, or when
      letters patent are issued or granted if subsequent thereto, and shall
      continue for a term of one year at which time they shall be subject to
      renewal for a further term of one year with the consent of all Parties,
      provided that the consent of Nortel and NMC shall not be required unless
      during the preceding one year term any of the termination provisions of
      section 5 have been held to be unenforceable for any reason. Except as
      aforesaid, such annual renewals shall continue for the entire duration
      of the patent rights under which such licenses are granted.

4     PRICE

4.1   The price to be paid by interWAVE to Nortel and NMC for the license and
      other rights granted herein shall be US$ 1 million, to be allocated 90
      percent to NMC and 10 percent to Nortel.


                                      7

4.2   Upon interWAVE's payment of the price set forth in Section 4.1, the
      licenses and rights granted to interWAVE in Section 2 shall thereafter
      be considered paid-up and royalty-free.


5     ASSIGNMENT AND CHANGE OF CONTROL

5.1   In the event that this Agreement is to be assigned or transferred by
      interWAVE, whether by way of merger, amalgamation, consolidation,
      reorganization, assignment, transfer, operation of law or otherwise
      ("Assignment") to a third party (the "Assignee") interWAVE shall, at
      least thirty (30) days prior to Assignment, provide written notice of
      such Assignment to the other Parties.

5.2   In the event of an Assignment, Nortel and NMC may, without any delay,
      by written notice, terminate this Agreement and all licenses and rights
      granted therein.

5.3   Notwithstanding section 5.2, provided that:

       (a)    the Assignee is not a Competitor of Nortel, as defined in
              section 5.9 below;

       (b)    interWAVE transfers substantially all of its assets to the
              Assignee, and the Assignee with whom interWAVE merges,
              amalgamates, consolidates or reorganizes thereby becomes the
              successor to the business of interWAVE;

       (c)    the financial condition of the Assignee as of the date of such
              assignment is not substantially worse than the financial
              condition of interWAVE as of the Effective Date of this
              Agreement; and

       (d)    such Assignee agrees in writing to Nortel (the
              "Acknowledgment") that it has assumed all obligations of
              interWAVE hereunder and that it shall be bound by the terms
              and conditions of this Agreement,

      Nortel and NMC shall grant to the Assignee licenses, similar in scope
      to those granted under this Agreement, for the manufacture, use, lease,
      and sale of Microcellular Infrastructure Products as defined and limited
      by the Definitions as they exist under this Agreement at the date
      immediately prior to the Assignment. Such license shall subsist only in
      respect of a level of sales of such Microcellular Infrastructure Products
      by such Assignee after such acquisition which does not materially exceed
      the level of such sales by the acquired entity immediately prior to such
      acquisition to be adjusted upwards on a yearly basis in accordance with
      normal growth rates in the industry.

5.4   In the event a third party (the "Acquiror") is to acquire a controlling
      interest (controlling not necessarily requiring greater than fifty
      percent (50%)) or a major


                                      8


<PAGE>


      equity participation in interWAVE ("Change of Control"), interWAVE
      shall, at least thirty (30) days prior to the Change of Control, provide
      written notice of such a change of control to Nortel.

5.5   In the event of a Change of Control, Nortel and NMC may, without any
      delay, by written notice, terminate this Agreement and all licenses and
      rights granted therein.

5.6   Notwithstanding the provisions of section 5.5, provided that the
      Acquiror is not a Competitor of Nortel, as defined in section 5.9 below,
      Nortel and NMC shall grant to interWAVE licenses, similar in scope to
      those granted under this Agreement, for the manufacture, use, lease, and
      sale of Microcellular Infrastructure Products as defined and limited by
      the Definitions as they exist under this Agreement at the date
      immediately prior to the Change of Control. Such licenses shall subsist
      only in respect of a level of sales of such Microcellular Infrastructure
      Products by interWAVE after such acquisition which does not materially
      exceed the level of such sales by interWAVE immediately prior to such
      acquisition to be adjusted upwards on a yearly basis in accordance with
      normal growth rates in the industry.

5.7   Where Nortel and NMC elect to terminate and not renew this Agreement
      under any of the provisions of Section 5 ("Termination"), Nortel and NMC
      shall refund to interWAVE, in either $US dollars or interWAVE shares at
      Nortel's option, an amount calculated in accordance with the provisions
      of Schedule E. Notwithstanding the foregoing, Nortel shall pay the refund
      in cash if the Fair Marker Value (in accordance with the principles
      articulated in Section 3.4(d)(iv)(d) of interWAVE's Bye-Laws) of one
      share of interWAVE Series G Preferred Stock is less than six dollars and
      six cents ($6.06) per share.

5.8   In the event a third party acquires a controlling interest (controlling
      not necessarily requiring greater than fifty percent (50%) interest) in
      interWAVE, resulting in the termination of the OEM Agreement in
      accordance with the provisions of the OEM Agreement, interWAVE shall
      grant to Nortel a personal, non-exclusive, non-assignable, world-wide
      license under all existing interWAVE patents and patent applications
      relating to Microcellular Public Radio Systems, such license extending
      for the full term of the applicable patents and applications and bearing
      a royalty of no greater than one percent (1%) of the net sales by Nortel
      of products covered by the claims of such patents and such applications
      when they issue as patents.

5.9   For the purpose of this section a "Competitor of Nortel" means any
      person with whom Nortel or NMC competes and which has greater than two
      percent marketshare in the wireless telecommunication infrastructure
      products market. Notwithstanding the foregoing, a person shall not be
      deemed to be a Competitor of Nortel simply by virtue of any competition
      arising solely from its acquisition of the business of interWAVE. Nortel
      shall, from time to time, upon request from and in consultation with
      interWAVE, provide interWAVE with a current list of


                                      9


<PAGE>


      Competitors of Nortel, and interWAVE shall be entitled to rely on such
      list for the purposes of this section until the later of:

              (i)   one hundred and eighty (180) days from the date of issued
                    by Nortel; or

              (ii)  the issuance of a revised list by Nortel.

5.10  Notwithstanding any assignment or Change of Control, the Parties hereto
      shall remain liable for their respective obligations hereunder.


6     MISCELLANEOUS PROVISIONS

6.1   Nothing contained in this Agreement shall be construed as:

       (a)    requiring the filing of any patent application, the securing
              of any patent or the maintaining of any patent in force;

       (b)    a warranty of representation by Nortel, or an admission by
              interWAVE, as to the validity or scope of any Nortel
              Infrastructure Patent, Sublicensed Patent or other Nortel patent;

       (c)    a warranty of representation that any manufacture, sale, lease
              or use will be free from infringement of patents other than those
              under which and to the extent to which licenses are in force
              hereunder;

       (d)    an agreement to bring or prosecute actions or suits against
              third parties for infringement;

       (e)    an obligation to furnish any manufacturing or technical
              information or assistance;

       (f)    conferring any right to use, in advertising, publicity or
              otherwise, any name, trade name or trademark, or any contraction,
              abbreviation or simulation thereof; or

       (g)    conferring by implication, estoppel or otherwise upon either
              Party any license or other right under any patent, except the
              licenses and rights expressly granted herein.

6.2   In the event of an enforceable decision or directive declaring invalid
      an essential part of this Agreement, without which this Agreement would
      not have been entered into, this Agreement may, at the option of any
      Party, be terminated upon the giving of notice to the other Parties. Save
      as before set forth, in the event that any term,


                                      10


<PAGE>


      clause, provision or condition of this Agreement shall be similarly
      adjudged invalid for any reason whatsoever, such invalidity shall not
      affect the validity or operation of any other term, clause, provision
      or condition and such invalid term, clause, provision or condition shall
      be deemed to have been deleted from this Agreement.

6.3   In the event interWAVE commits any act of bankruptcy, or compounds with
      its creditors; or a petition or receiving order in bankruptcy is
      presented or made against interWAVE; or a petition for an administration
      order is presented in relation to interWAVE; or a resolution or petition
      to wind up interWAVE (other than for a legal reconstruction,
      reorganization or amalgamation) or a receiver or administrative receiver
      is appointed; and such act or petition is not cured, dismissed, or
      withdrawn within sixty (60) days thereafter; or interWAVE ceases to carry
      on business, Nortel may, without any delay, by notice, terminate this
      Agreement.

6.4   Any and all notices and other information to be given by one of the
      Parties to the other shall be deemed sufficiently given when forwarded by

      proceedings to enforce, or which arise in connection with or relate to,
      this Agreement, any of the agreements in the form of Exhibits hereto or
      any of the transactions contemplated hereby or thereby shall be brought

      District of California (or, in the event such court does not have
      jurisdiction, the courts of the State of California located in such
      district), unless such actions or proceedings are required to be brought
      in another court to obtain subject matter jurisdiction over the matter
      in controversy. In any such actions or


                                      12

                           For purposes of this Agreement, a "Semester" shall
mean a six (6) month period commencing on January first or July first of any
year during the term of this Agreement, provided that the first Semester shall
commence on the Effective Date and end on June 30, 2000.

                  14.5     Shortfall Payment

                           14.5.1 Provided that ALCATEL uses commercially
reasonable efforts to sell the volumes of Product or use the Support and
Services covered by this Agreement, in the event that ALCATEL fails to meet the
Semester Commitment stated above for any Semester, SUPPLIER'S sole remedy and
ALCATEL's total liability shall be calculated as follows:

                                    (a) ALCATEL may carryover up to [*****]
of the Semester Commitment for a given Semester to the next Semester, provided
that in no event may any amount carried over from the preceding Semester to
the current Semester be carried over to the next Semester. The actual
carryover amount from any semester (the "Carryover Amount") shall be equal to
the lesser of (i) [*****]  of the Semester Commitment for such Semester; and
(ii) the sum of the Semester Commitment for such Semester and the Carryover
Amount from the immediately preceding Semester less the amount actually
purchased during such Semester.

                                    (b) If, at the end of any Semester, the
amount actually purchased during such Semester is less than the sum of the
Carryover Amount from the previous Semester and [*****] of the Semester
Commitment for the current Semester, then ALCATEL shall pay SUPPLIER a
shortfall payment of [*****]  of such difference. SUPPLIER shall invoice
ALCATEL for such shortfall payment after the end of such Semester, and
ALCATEL shall pay such invoice in accordance with Article 17.

                                    (c) If, at the end of any Semester, the
amount actually purchased during such Semester exceeds the sum of the
Semester Commitment for such Semester and the Carryover Amount from the
preceding Semester, then ALCATEL shall receive a credit against purchases
equal to the lesser of: (i) the shortfall payment actually paid by ALCATEL
pursuant to Section 14.5.l(b) for a shortfall in the previous Semester, and
(ii) [*****]  of the amount by which the volume actually purchased during the
current Semester exceeds the sum of the Semester Commitment for such Semester
and the Carryover Amount from the preceding Semester.

                                    d) At the end of each Calendar Year, the
Parties will make the grand total of all ALCATEL and its Associated Companies'
purchases during this Calendar Year.

                                    If ALCATEL and its Associated Companies have
reached their Purchase commitments here above mentioned, ALCATEL shall be
completely reimbursed by SUPPLIER of all shortfall payments paid by ALCATEL
during the first Semester.

         Unless mutually agreed by the Parties, if SUPPLIER delays meeting the
general availability dates for any agreed upon Release milestones exceeds six
(6) months, then ALCATEL's volume commitments for that calendar year are hereby
terminated.

                           each of the first six months in the forecast shall
                           not vary by more than twenty-five percent (25%) from

                           percent (50%) from the amount forecasted.

                  -        The rolling forecast shall not be construed as an
                           Order, provided that ALCATEL may only change the
                           quantities as stated above.

                                    (a) arises during the warranty period of the
Products in question; or

                                    (b) arises after expiration of the warranty
period but is due to non-conformity of the Product with SUPPLIERS

longer repair such Products, SUPPLIER agrees to propose an alternative solution
which could include an end of life buy pursuant to Section 15.3, appointment by
SUPPLIER of a third party to repair such Products, or transfer of repair
technology.

granted with respect to a specific New Version Release prior to the end of the
second complete calendar quarter following SUPPLIER's designation of that
Release being generally available. The date that SUPPLIER grants such license to
ALCATEL for a specific New Version Release shall be called "Manufacturing
License Commencement" (MLC) for such Product Release.

         SUPPLIER shall provide, and this Manufacturing License for a specific
New Version Release shall permit ALCATEL or its Associated Companies to use the

                  terms and conditions as SUPPLIER gets ASICs from its own
                  suppliers (procurement will be made either from SUPPLIER, or
                  from SUPPLIER's suppliers directly with written authorization
                  given by SUPPLIER to its own suppliers).

its Associated Companies, such contractor approved in writing and in advance by
SUPPLIER and such approval shall not be unreasonably withheld.

         ALCATEL and/or its Associated Companies agree to pay SUPPLIER a royalty
amount based upon the prices listed in Annex D effective immediately before
Manufacturing License Commencement (the "Transfer Price") which royalty shall be
calculated for each New Version Release in accordance with the table shown
below. If SUPPLIER reduces the price for a Product after Manufacturing License
Commencement, the Transfer Price shall be reduced by a factor equivalent to the
same factor by which the price for the SUPPLIER Product is reduced.

         If Manufacturing License Commencement for a specific New Version
Release occurs during the term of this Agreement, then the manufacturing license
for such New Version Release granted in this provision shall survive any
termination or expiration of this Agreement for three (3) years, except when the
Agreement is terminated by supplier under Section 30.1 or 30.3.

         (corporate GSM server) and BSS in 2 cases
         1) using SS7 signalling over PCM

<PAGE>

         2)  using GSM signalling over IP

         CGS includes functional blocks providing signalling adaptation, The GW
         PBX provides the Call handling services
         Several steps are identified and a road map allowing a cost
         optimisation  including IP connection is also considered.
         Note: CMS corporate mobility server
         General description of CMS is given in appendix 1

2. CGS INTERFACES TO BSS

2.1 STEP 1: SS7 INTERFACE

         With the Step 1, the CGS is connected to the interface. No modification
         is needed on the BSS (BSC + BTS).

- -    Signalling aspects
         The BSC is linked to the CGS via A link ( PCM )
         "A" signalling is carried in 64K Channels (eg NDEG.16).
         In the normal BSS / MSC configuration origin & destination point CODE
         (OPC/ DPC) need to be defined eg: BSC PC XXX, MSC PC YYY.
         The CGS will interface BSC and MSC without any addressing modification
         as described below


                                       [GRAPHIC]

                   [graphic shows, in general terms, the BSC
                   interfacing with the MSC through the CGS]

- -        Functional interworking

                 The protocols architecture is defined as below:

                                       [GRAPHIC]

                  [graphic shows, in specific terms, the BSC
                  interfacing with the MSC through the CGS]

<PAGE>

- -    TCH aspects

         In the normal BSS / MSC configuration all PCM link are linked between
BSC and MSC.
         When the CGS is introduced, a PCM link (TCH only) from the BSC is
connected to the GW PBX


                                       [GRAPHIC]

                   [graphic shows the BSC interfacing with the
                MSC through the CGS and the PCM link to the TCM]

         The PCM, which links the BSC to the CGS, will be managed by the CGS
(selection of channels ...)

         The BSC is configured with 2 PCM (which seems to be linked directly to
the MSC).

         It is assumed that TCH are provided on a PCM G703 / G704 (voice
channels at 64 k bits).

- -    Link between CGS and GWPBX

         The link between the CGS and the GWPBX is Alcatel proprietary.

- -    Synchronization

         It is assumed that the MSC provides clock reference via PCM links
         connected to the BSC.
         When the clock signal is carried over the A interface connected
         to the CGS.
         The MSC will be the master, the CGS the slave. (Its internal
         clock will use the MSC clock).
         The CGS will transmit the clock signal to the BSC.
         The BSC will be the slave and use the CGS /MSC clock for its
         internal use.

         It is assumed that the GWPBX will be synchronised from the public
         network.

- -    SUMMARY of the CGS / BSS interface

         The interface between CGS and BSC is based on two PCM links

<PAGE>

                                     [GRAPHIC]

                   [graphic shows the BCS interfacing with the
                          MSC based on two PCM links]

- -    Configuration

         - TRAFFIC
         The CGS is designed to allow 80 - 100 erlangs with the PBX. ( 1000
         GSM terminals with 0.1 E )

         - PBX LINK
         The CGS is able to control 4PCM to the PBX. This capacity can be
         extended up 8 PCM

         - BSC/MSC links: A interface with signalling.
         All A interfaces which carry the A signalling must be linked to the
         CGS.
         The capacity of the CGS is under definition,
         the objective is support at least 4 A interfaces.

2.2 STEP 2 : IP INTERFACE BETWEEN CGS AND BSS

         The IP interface between CGS and BSC may be carried on IP link,
         2-sub-steps is identified.

         Step 2a) A signalling over IP and TCH over PCM (64K)

         step 2b)
         -    A signalling over IP & TCH over IP and or
         -    H323 signalling and TCH over IP
                  (specific 'adaptation' of H323 may be needed to carry all GSM
                  information, as far as possible all generic mechanisms to
                  carry additional information will be preferred)

<PAGE>

- -    Step 2 a) < < A > >  over IP.

         THE OBJECTIVE IS TO AVOID SS7 BOARDS HANDLING SS7 LOW LAYERS. (MTP 1 -2
         -3)

         Basic principle:
         The deviation of signalling which was possible using S87 boards should
         be mapped to a < < BSC > > deviation of signalling using IP to the CGS

         It is proposed that the BSC deviate the signalling GSM to the CGS over
         an IP link which will return to the BSC the signalling after
         processing.
         The BSC will then forward the signaling to the MSC over the PCM SS7
         channels.

         In a similar way, in the opposite direction the SS7 signalling over PCM
         coming from the MSC is first deviated to the CGS. The CGS will return
         the signalling on IP to the BSC for processing.

                     [graphic that shows the BSC connected
                      to the MSC through the IP deviator]

- -    Protocol architecture

         It is proposed to interface the CGS directly at the SSCP level or
equivalent.

         For the BSC the connection to the CGS must not impact any signalling
procedures.

<PAGE>

The protocol architecture could be the following:




                                    [GRAPHIC]

            [graphic that shows the possible protocol architecture
                of the CGS and MSC, including the BSSAP and CGSA]

         The link between the CGS and the BSC corresponds to the internal link
between SCCP layer and MTP layer.

         The information (messages transfert part primitives) will be carried on
IP link TCP (or UDP)
         See REC Q701 para 8, MTP primitives:
         - MTP transfer
         - MTP pause
         - MTP resume
         - MTP status.

- -    PCM TRUNKS
         The BSC will have the normal SS7 interface (A or Ater interface) with
         the MSC
         The BSC will have 2 type PCM trunks
               'Public' PCM trunks for GSM calls routed to the MSC
               "corporate" PCM trunks for GSM calls routed to GW PBX.

         All alarms related to "Corporate" PCM trunks must not be transmitted to
the MSC.

                              ----------------------

- -    RELIABILITY
         In case of CGS failure or IP link failure between CGS / BSC publics
         calls must always be possible.

- -    Other requirements

         General rules


<PAGE>



         - Any signalling which relates to calls using corporate trunks must not
be transmitted to the public MSC

         - Handshake process (CGS/BSC) should allow reconfiguration which
guarantees minimum quality of service..

         - Alarms: in case of IP link failure an alarm is sent to the supplier
OMC.

       DOCUMENTATION

Supplier shall furnish to Alcatel, free of charge, all relevant documentation
relating to the CGS IP link software, such that Alcatel may produce its own
finished literature. Alcatel shall have the right to use solely for use on or in
conjunction with the Products, reproduce and apply its trademark or copyright on
such documentation and supply the same to its Customers.
     Documentation shall be Supplier standard documentation and furnished in
paper form and electronic form (worldwide standard).

3. GENERAL DESCRIPTION OF CORPORATE MOBILITY SERVER
(CMS)

3.1 SYSTEM ARCHITECTURE

         The general concept is based on a server called CMS server which
interfaces the BSS (BSC+BTS) and the PBX.





                                   [GRAPHIC]

                     [graphic that shows the offsite MSC
                  connected to the onsite GSM air interface]

<PAGE>



         The PLMN sees the corporate BSS as standard BSS. With our CMS, this BSS
allows local routing of local calls for corporate GSM users. For these local
calls, the public MSC is not involved. There is no charging ticket in the PLMN.
By local routing of local calls we mean:

- - Calls from mobile to mobile
- - Calls from mobile to PBX fixed phone
- - Calls from PBX fixed phone to mobile
- - Calls from mobile to PSTN fixed phone
- - Calls from PSTN fixed phone to mobile

         The system can welcome visitors. Visitors, if allowed, are then seen as
public GSM users. They systematically will use A interface for calls. All
visitors' calls will be handled by the public MSC. For that calls public
charging is used
         The GSM PBX is a mono company equipment. It also means that the BSS is
dedicated to one company.

         The PBX interface we use depends on Client PBX capabilities. Between
mobiles the level of features depends on CMS call handling capabilities. Between
fixed PBX lines and mobile lines, the level of features depends on PBX
signalling (QSIG, DPNSS)

         The mobility Management (e.g. localization) is handled by the PLMN
(HLR, VLR) with the standard GSM protocol procedures.

3.2 CMS / PBX INTEROPERABILITY







                                   [GRAPHIC]

                [graphic that shows the transmission of voice
                  and other signals between the BSC and MSC]
<PAGE>


The CMS relies on two main blocks:

- -   A CGS: Corporate GSM Server
- -   A PBX GW: PBX gateway

The BSS brings indoor coverage with the required level of capacity.

         The CGS is ensuring local routing of local calls. Today the
signaling between CGS and BSC is SS7 signalling. Signalling on IP will be
available later on.
The CGS is analysing the signalling and decides whether or not he has to
locally route the call.

USERS

2 types of GSM users are identified:

- -   Corporate GSM users:

         The corporate GSM users are registered in the CGs thanks to
their IMSI and in the gateway PBX by their directory number. They are also
attached to the PLMN network for authentication, ciphering and localisation
procedures.

- -   Visitors GSM users:

         The visitors GSM users are unknown by the CGS, nevertheless they can
use the corporate radio coverage and keep the GSM services provided by their
operator.

Call scenario for visitors GSM users:

         The visitors GSM establish or receive their calls directly through the
PLMN. The CMS is transparent.

Call scenario for corporate GSM users:

         The corporate GSM users can make calls using the PLMN numbering plan or
the corporate numbering plan. In order to differentiate the two numbering plans
a prefix is necessary to access the corporate numbering plan.
         The corporate GSM users are called by their directory number part of
the DDI range of the PBX. When off site the UBIQUITY services can redirect the
call to the PLMN network.

physical condition thereof, including accessibility and location of utilities,
improvements and the presence or absence of Hazardous Materials (as defined
below), and any other matters relating to the Premises, the Building or the

Tenant's purposes or Tenant's willingness to enter into this Lease. Tenant has
and will rely solely on Tenant's own inspection and examination of such items.

                  (c)      Notwithstanding  the  provisions  of this  Section
1.4. Landlord hereby expressly discloses to Tenant that full telephone service

<PAGE>


point of entry within Building I, with lines from such point of entry connected
directly to Pacific Bell) shall be available on or before January 1, 2000. If
full telephone service is not available until subsequent to January 1, 2000,
Tenant will continue to pay the reduced Monthly Base Rent set forth in Section
3.1 below, until the later of (i) fifteen (15) days after the date on which full

                         ARTICLE 2 - TERM AND POSSESSION

                  Section 2.1       TERM.

                  (a)      This Lease shall become effective upon execution by
Landlord and Tenant. The term of this Lease ("Term") shall commence on the date
calculated as provided in subparagraph (b) below ("Commencement Date"), and
shall continue for a period of five (5) years, one month thereafter, unless
earlier terminated in accordance with this Lease or unless extended as
hereinafter provided. If Landlord shall not deliver possession of the Premises
to Tenant in the manner provided under subparagraph (b) below on or before the
"Scheduled Commencement Date" specified in the Basic Lease Information for any
reason whatsoever. Landlord shall not be liable to Tenant by reason thereof and,
except as provided below, this Lease and the parties' obligations hereunder
shall not be rendered void or voidable thereby or otherwise affected in any
manner, except that Tenant's obligation to pay Monthly Base Rent (as defined
below) and other amounts payable by Tenant under this Lease shall not commence
until the Commencement Date. In addition, no delay by Landlord in the delivery
of possession of the Premises to Tenant shall extend the Term or any obligation
of Landlord hereunder. In the event that the Commencement Date has not occurred
prior to March 1, 2000, Tenant shall have the right to terminate this Lease by
delivering written notice to Landlord of such election to terminate on or before
ten (10) days thereafter, in which event any sums paid by Tenant to Landlord
shall be immediately returned to Tenant.

                  (b)      The Commencement Date shall be the date upon which
Landlord delivers possession of the Premises, other than the Landlord Retained
Area, to Tenant. At such time as the Commencement Date has been established, at
Landlord's request, Landlord and Tenant shall execute a written acknowledgment
of the Commencement Date. For the purposes of this Lease, the term "Landlord
Retained Area" shall mean the portion of the first floor of the Premises
occupied by Landlord's payroll group and containing approximately 1,340 square
feet of rentable area, as shown on EXHIBIT A. Landlord shall deliver possession
of the Landlord Retained Area to Tenant on or before February 1, 2000. If
Landlord shall fail to deliver possession of the Landlord Retained Area to
Tenant on or before February 1, 2000, Tenant's obligation to pay to Landlord
Monthly Base Rent with respect to the Landlord Retained Area shall be abated
until such time as Landlord shall deliver possession of the Landlord Retained
Area to Tenant. If Landlord does not deliver possession of the Landlord Retained
Area to Tenant on or before March 1, 2000. Tenant's obligation to pay to
Landlord Monthly Base Rent with


                                     3
<PAGE>


respect to the Landlord Retained Area shall be abated for each day of such delay
in delivery beyond March 1, 2000.

                  (c)      On the date of Landlord's delivery of possession of
the Premises to Tenant pursuant to this Section, the portion of the Premises so
delivered shall be clean and the Building systems located therein shall be in
good operating condition. Tenant's occupancy of the Premises (whether before or
after the Scheduled Commencement Date) shall constitute Tenant's acceptance of
the Premises and acknowledgment that the Premises are in such condition and
otherwise in good order and satisfactory to Tenant.

                  Section 2.2       IMPROVEMENTS Without limiting any other
provisions of this Agreement, Tenant expressly acknowledges and agrees that
Landlord shall have no obligation whatsoever to construct any tenant
improvements or other alterations, additions or improvements in or to the
Premises or Building, or, apart from Landlord's obligations under Section 2.l(c)
above, otherwise to prepare the Premises or Building for Tenant's occupancy.

purposes of this Lease, the term "Tenant's Share of Taxes" shall mean the
product of Tenant's Tax Share (as hereinafter defined), multiplied by the

quarterly basis, as applicable, during the year covered by such Insurance
Statement, then Tenant shall pay in cash any sums owed Landlord within ten (10)
business days thereafter, or, if applicable, Tenant shall receive a credit
against any the Excess Insurance Costs next accruing for any sums owed Tenant.
If the Term of this Lease commences on a date other than the first day of the
calendar year or expires or is terminated on a date other than the last day of
the calendar year, the amount of Insurance Costs with respect to which Tenant
shall be obligated to pay its share during the year in which the Lease commences

Following the expiration of the calendar year in which the Term expires or is
terminated. Landlord shall give a final Insurance Statement to Tenant for such
calendar year. If the Excess Insurance Costs as shown on such final Insurance
Statement are greater or less than the total amounts actually paid by Tenant as

forms of coverage and on such amounts as Landlord, in its sole discretion, shall
elect to maintain with respect to the Building or Project. In the case of
blanket insurance policies covering the Project and other property of Landlord,
Insurance Costs shall include the costs and expenses thereof allocated by
Landlord to the Project. For purposes of this Lease, the term "Tenant's Share of
Insurance Costs" shall mean the product of Tenant's Insurance Share (as
hereinafter defined) multiplied by the amount of the Insurance Costs for the
year in question. For the purposes of this Lease "Tenant's Insurance Share"

Landlord shall not be liable for any failure to provide access to the Premises,

resulting from such failure or to any diminution or abatement in any rent or
other amounts payable by Tenant hereunder. Landlord shall take commercially
reasonable action to minimize the interruptions so caused and the adverse impact
accruing therefrom to the extent reasonably possible. In no event shall such

or guideline of any appropriate governmental authority, including, without
limitation, the making of alterations to such buildings. Landlord may also
comply with such request or guideline. Neither such compliance (as set forth

diminution, or abatement in rent or other amounts payable by Tenant under
this Lease or constitute or be construed as a constructive or other eviction
of Tenant. Tenant shall comply with all mandatory rules, regulations and
requirements promulgated by the applicable governmental authorities or

designated for removal at the time of expiration or earlier termination of the
Lease. Following any such removal of any of the Alterations, Tenant, at its sole
cost and expense, shall repair and restore the Premises to their original
condition.

Tenant's obligations arising under this Lease on and after the date of such
assignment. Any such assignee shall, upon demand, execute and deliver to
Landlord an instrument confirming such assumption. No provision of this Lease

Uninsured Casualty, Landlord shall have the right to (a) rebuild or restore the

contrary contained in this Article 11, in the event that the Premises, the
Building and/or the Project are damaged or destroyed in whole or in part from

shall Landlord have any liability for, nor shall Landlord be required to repair
or restore, any injury or damage to any Alterations made by Tenant, trade
fixtures, equipment, merchandise, furniture or any other property installed by
Tenant or at the expense of Tenant. If Landlord or Tenant do not elect to
terminate this Lease pursuant to this Article 11, Tenant shall promptly rebuild
or restore all such property to the condition existing immediately prior to the
event of damage or destruction.

                  Section 11.8. WAIVER OF CERTAIN REMEDIES. Landlord and Tenant
acknowledge that the rights and obligations of the parties in the event of the
damage or destruction of the Premises are as set forth in this Article 11.
Tenant hereby expressly waives any rights to terminate this Lease upon damage or
destruction of the Premises, except as specifically provided by this Lease,
including, without limitation, any rights pursuant to the provisions of Sections
1932(2) and 1933(4) of the California Civil Code, as amended, or any other,
similar provisions of law.

                           ARTICLE 12 - EMINENT DOMAIN

                  Section 12.1. TAKING OF PREMISES. If all or any portion of the
Premises shall be taken by any public or quasi-public authority as a result of
the exercise of the power of eminent domain (which shall include a voluntary
sale or transfer by Landlord of all or any portion of the Premises under threat
of condemnation), this Lease shall terminate as to the part so taken as of the
date of taking, and, in the case of a partial taking which, in the reasonable
judgment of Tenant, materially impairs Tenant's ability to conduct its business
on the remainder of the Premises, Tenant shall have the right to terminate this
Lease as to the remainder of the Premises by written notice given to Landlord
within thirty (30) days after the date of such taking. If a material portion of
the Building or the Project is taken or if substantial alteration or
reconstruction of the Premises, the Building and/or the Project will, in
Landlord's reasonable judgment, be necessary or desirable as a result of such
condemnation or taking, Landlord may terminate this Lease by written notice
given to Tenant within thirty (30) days after the date of such taking.

                  Section 12.2. TEMPORARY TAKING. If all of the Premises shall
be temporarily condemned or taken for governmental occupancy for a period of
more than


                                      25
<PAGE>

one (1) year, this Lease shall terminate as of the date of taking, and Landlord
shall be entitled to any and all compensation, damages, income, rent and awards
in connection therewith. In the event of a temporary taking for a period of one
(1) year or less, this Lease shall remain in full force and effect, and all
compensation awarded as a result of such taking during the term of this Lease
(regardless of whether such temporary taking lasts for less or more than one (1)
year) shall be payable to Tenant.

                  Section 12.3. ABATEMENT OF RENT. If any portion of the
Premises shall be taken in eminent domain and this Lease shall not be terminated
as provided in this Article 12, as of the date of the taking, the Monthly Base
Rent, the Excess Taxes and Excess Insurance Costs shall be reduced in the same
proportion that the rentable area of that portion of the Premises so taken bears
to the original rentable area of the Premises.

                  Section 12.4. CONDEMNATION AWARD. Except as otherwise provided
in Section 12.2 above, in the event of any taking, Landlord shall be entitled to
any and all compensation, damages, income, rent, awards, and any interest
therein whatsoever which may be paid or made in connection therewith; provided,
however, that Tenant may make a separate petition, if such a separate petition
is permitted, for the cost of its moving expenses and the value of its personal
property (whether or not affixed to the Premises). In no event shall Tenant be
entitled to receive any award for any "bonus value" of this Lease or otherwise
attributable to the value of Tenant's interest under this Lease or in or to the
Premises. Each party hereby waives the provisions of California Code of Civil
Procedure Sections 1265.120 and 1265.130 allowing either party to petition the
Superior Court to terminate this Lease in the event of a partial taking of the
Premises.

                             ARTICLE 13 - INSURANCE

                  Section 13.1. LIABILITY INSURANCE. Tenant, at its sole cost
and expense, shall procure and maintain in full force and effect throughout the
Term (a) a policy of commercial general liability insurance in the minimum
amount of not less than Five Million Dollars ($5,000,000.00) combined annual
aggregate limits for bodily injury and property damage (with no lower per
occurrence limits), including contractual liability and personal injury
coverage, insuring Tenant against any liability arising out of or in connection
with Tenant's use, occupancy and/or maintenance of the Premises, the Building or
the Project, or arising out of this Lease, and (b) commercial automobile
insurance in the minimum amount of Two Million Dollars ($2,000,000) combined
single limit coveting all owned, non-owned or leased vehicles on or about the
Premises and Project. Such commercial general liability insurance shall name
Landlord, Landlord's mortgagee (of whom Tenant has been notified), if any, and
Landlord's property manager (of whom Tenant has been notified), if any, as
additional insureds, shall specifically include the liability assumed hereunder
by Tenant (provided, however, that the amount of such insurance shall not be
construed to limit the liability of Tenant hereunder), and shall provide that it
is primary insurance and not "excess over" or contributory with any other


                                      26
<PAGE>

insurance in force for or on behalf of Landlord. The policy shall eliminate
cross-liability and shall contain a severability of interest clause. Landlord
shall have the right, periodically during the Term, but not more frequently than
once each twelve (12) months, to require that Tenant increase the minimum
liability limits specified in this Section to an amount equal to the
then-prevailing minimum liability limits required by prudent landlords of
comparable office buildings in Menlo Park/Palo Alto, California area, as
determined by Landlord in its reasonable judgment.

                  Section 13.2. TENANT'S PROPERTY INSURANCE. Tenant, at its sole
cost and expense, shall procure and maintain in full force and effect throughout
the Term a policy of "all risk" property insurance, with theft, vandalism and
malicious mischief endorsements, covering any Alterations and Tenant's trade
fixtures, equipment, fixtures, furnishings and other personal property located
in or on the Premises, to the extent of at least full replacement cost thereof,
without any deduction for depreciation, and with a stated value endorsement
specifying an amount not less than the actual replacement cost thereof. Such
property insurance shall include "loss of rents" coverage sufficient to cover
Tenant's obligation to pay Monthly Base Rental and other amount payable under
this Lease for a twelve (12) month period. In the event that Tenant shall suffer
an insurable loss under such policy, the proceeds from any such policy shall be
used by Tenant for the replacement or restoration of such Alterations, trade
fixtures, equipment, inventory, fixtures, furnishings and personal property.

                  Section 13.3. TENANT'S ADDITIONAL INSURANCE. Tenant, at its
sole cost and expense, shall also procure and maintain in full force and effect
throughout the Term such additional insurance with such forms of coverage and in
such amounts as Landlord shall reasonably require, including, without
limitation, workers' compensation and employers' liability coverage as required
by law.

                  Section 13.4. INSURANCE CRITERIA. All insurance required to be
maintained by Tenant under this Lease shall (a) be issued by insurance companies
authorized to do business in the State of California (or if not so authorized,
reasonably approved by Landlord in writing) with a financial rating of at least
a A-VIII or better as rated in the most recent edition of "Best's Insurance
Guide"; (b) be issued as a primary policy; and (c) contain an endorsement
requiring not less than thirty (30) days' written notice from the insurance
company to Landlord and to Landlord's mortgagee before cancellation of any such
policy, except in the case of nonpayment, in which event such policy may be
cancelled upon ten (10) days' prior written notice.

                  Section 13.5. EVIDENCE OF COVERAGE. Tenant shall deposit
with Landlord, at the commencement of the Term, and on renewal of each policy
not less than twenty (20) days prior to expiration of such policy, a certified
copy of each insurance policy required to be carried by Tenant hereunder, or a
certificate of insurance as to such policy, together with evidence of payment of
premiums.

<PAGE>

                  Section 13.6. WAIVER OF SUBROGATION. Landlord and Tenant each
hereby waives any and all rights of recovery against the other party for loss of
or damage to such waiving party or its property, where such loss or damage is
insured against under any insurance policy in force at the time of such loss or
damage. To the extent that such insurance endorsement is available at no or
nominal additional premium charge and does not adversely affect the ability of
such party to obtain such insurance, Landlord and Tenant each agree to obtain
for the benefit of the other party in the insurance policies carried by the
first party a waiver of any right of subrogation which any insurer of the party
may acquire.

                         ARTICLE 14 - WAIVER; INDEMNITY

                  Section 14.1. WAIVER OF LIABILITY. Landlord shall not be
liable for, and Tenant hereby waives all claims against Landlord with respect
to, any death or injury of any nature whatsoever that may be suffered or
sustained by Tenant or any employee, licensee, invitee, guest, agent or customer
of Tenant or any other person, from any causes whatsoever; or for any loss or
damage or injury to any property outside or within the Premises belonging to
Tenant or its employees, agents, customers, licensees, invitees, guests or any
other person, except to the extent that, in either event, such injury or damage
is caused by the gross negligence or willful misconduct of Landlord, its
employees or agents. Without limiting the generality of the waiver of liability
contained in this Section, Landlord shall not be liable for any damage of any
nature whatsoever to persons or property caused by explosion, fire or theft; by
breakage of any sprinkler, drainage or plumbing systems; by failure for any
cause to supply adequate drainage; by the interruption of any utility or other
service; by steam, gas, water, rain or other substances leaking, issuing or
flowing into any part of the Premises; by acts of God or the elements, acts of
public enemy, riot, strike, insurrection, war, court order, requisition or order
of governmental body or authority; by repair, maintenance or alteration of any
part of the Building or the Project (including any repair, maintenance or work
of construction performed by Tenant), or by anything done or omitted to be done
by any tenant, occupant or person in the Building or the Project, except to the
extent that any of the foregoing shall be caused by the gross negligence or
willful misconduct of Landlord, its employees or agents. Notwithstanding the
foregoing, in no event shall Landlord be liable or responsible in any way for
any loss of business by Tenant, lost profits of Tenant or any other
consequential damages of Tenant or its employees, agents, customers, licensees,
invitees, guests or any other person, regardless of the cause therefor.

                  Section 14.2. TENANT'S INDEMNITY. Tenant shall indemnify,
defend and hold Landlord, its employees, agents and contractors, harmless from
and against any and all losses, costs, claims, damages, liabilities or causes of
action (including attorneys' fees) arising out of or in any way connected with:
(a) Tenant's use or occupancy of the Premises or the conduct of Tenant's
business thereon, or any activity, work or other thing done, permitted or
suffered by Tenant in or about the Premises, the Building or the


                                      28
<PAGE>

Project, except to the extent caused by the gross negligence or willful
misconduct of Landlord, its employees or agents; (b) any damage to any property,
or injury, illness or death of any person occurring in, on, or about the
Premises, or any part thereof, arising at any time and from any cause
whatsoever, except to the extent caused by the gross negligence or willful
misconduct of Landlord, its employees or agents; (c) any damage to any property
or injury, illness or death of any person occurring in, on, or about any part of
the Building or the Project other than the Premises, to the extent such damage,
injury, illness or death shall be caused in whole or in part by the negligence
or willful misconduct of Tenant, its agents, employees, invitees, licensees or
customers; and (d) arising out of Tenant's breach of the provisions of this
Lease. The provisions of this Section shall survive the termination of this
Lease.

                              ARTICLE 15 - DEFAULT

                  Section 15.1. EVENTS OF DEFAULT. In addition to any other
event specified in this Lease as an event of default, the occurrence of any one
or more of the following events shall constitute a default under this Lease by
Tenant:

                  (a)      Tenant's failure to pay when due any Monthly Base
Rent, Excess Taxes. Excess Insurance Costs, Excess Utility Charges or any other
amounts that Tenant is obligated to pay to Landlord pursuant to this Lease;
provided, however, on not more than one occasion in any twelve (12) consecutive
month period throughout the Term, Tenant's failure to pay rent when due shall
not constitute an Event of Default unless such failure shall continue for five
(5) days following written notice thereof from Landlord;

                  (b)      Tenant's failure to perform any other covenant,
agreement or obligation of Tenant contained in this Lease within thirty (30)
days following Landlord's written notice thereof to Tenant;

                  (c)      Tenant's abandonment of the Premises, or Tenant's
vacation of the Premises without providing adequate security for the Premises;

                  (d)      Tenant's making of any general assignment for the
benefit of creditors; or the commencement and continuation for at least thirty
(30) days of any case, action or proceeding by, against or concerning Tenant
under the Bankruptcy Code or any other federal or state bankruptcy, insolvency
or debtor's relief law or otherwise seeking Tenant's financial reorganization or
an arrangement with any of Tenant's creditors;

                  (e)      Appointment of receiver, trustee or other person to
take possession of substantially all of Tenant's assets;

                  (f)      Commencement of proceedings for winding up or
dissolving (whether voluntary or involuntary) Tenant, if Tenant is a
corporation, partnership or limited liability company;


                                      29
<PAGE>

                  (g)      Levy of a writ of attachment or execution on Tenant's
interest under this Lease, if such writ continues for a period of thirty (30)
days; and

                  (h)      Assignment of this Lease or any interest hereunder,
or sublease of all or any portion of this Premises, in violation of the
provisions of Article 10 of this Lease.

                  Section 15.2. LANDLORD'S REMEDIES. If a default by Tenant
under this Lease shall occur, in addition to any other rights and remedies
available to Landlord at law or in equity (including, without limitation, the
provisions of Section 1951.4 of the California Civil Code or any successor
statutory provision), Landlord at any time thereafter shall have the right to
give a written notice of termination of this Lease to Tenant, and on the date
specified in such notice (which shall be not less than three (3) days after the
giving of such notice), Tenant's right to possession of the Premises and this
Lease shall terminate, unless on or before such date all arrears of Monthly Base
Rent and all other sums payable by Tenant under this Lease and all costs and
expenses incurred by Landlord with respect to such default shall have been paid
by Tenant, and any other breaches of this Lease by Tenant at that time existing
shall have been fully remedied to the satisfaction of Landlord. If Landlord
shall terminate this Lease pursuant to the provisions of this Section, Landlord
shall have all the rights and remedies of a landlord provided by Section 1951.2
of the California Civil Code or any successor statutory provision. Upon such
termination, in addition to any other rights and remedies to which Landlord may
be entitled under applicable law, Landlord may recover from Tenant: (a) the
worth at the time of award of all unpaid rent which had been earned at the time
of termination; (b) the worth at the time of award of the amount by which all
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rent loss that Tenant proves could have been
reasonably avoided; (c) the worth at the time of award of the amount by which
all unpaid rent for the balance of the term of this Lease after the time of
award exceeds the amount of such rent loss that Tenant proves could be
reasonably avoided; and (d) 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, including, without limitation, attorneys' fees and
costs; brokerage commissions; the cost of alterations, additions, improvements,
renovations, refurbishment and repair of the Premises; the cost of removal and
storage of Tenant's trade fixtures, equipment, fixtures, furnishings and other
personal property located in the Premises; and the unamortized portion, as of
the date of termination of this Lease, of any Tenant Improvements constructed or
installed by Landlord at its expense (as amortized over the Term with interest
thereon at the Interest Rate). The "worth at the time of award" of the amounts
referred to in clauses (a) and (b) above shall be computed by allowing interest
at the Interest Rate. The worth at the time of award of the amount referred to
in clause (c) above shall be computed by discounting such amount at a rate equal
to the discount rate of the Federal Reserve Bank of San Francisco at the time of
award plus one percent (1%).

                  Section 15.3. LATE CHARGES; INTEREST. Tenant acknowledges that
late payment by Tenant to Landlord of Monthly Base Rent, Excess Expenses, Excess
Taxes, Excess Insurance Costs, Excess Utility Charges or any other amounts
payable by Tenant to Landlord under this Lease will cause Landlord to incur
costs not contemplated by this Lease, the exact amount of such costs being
extremely difficult and impracticable to ascertain. Such costs include, without
limitation, processing and accounting charges, and late charges that may be
imposed on Landlord by the terms of any indebtedness secured by an encumbrance
covering the Premises. Therefore, if any such amount due from Tenant is not
received by Landlord within seven (7) days after the same shall become due and
payable, Tenant shall pay to Landlord on demand an additional sum equal to five
percent (5%) of the overdue amount as a late charge. The parties agree that this
late charge represents a fair and reasonable estimate of the costs that Landlord
will incur by reason of such late payment by Tenant. Acceptance of any late
charge shall not constitute a waiver of Tenant's default with respect to the
overdue amount, or prevent Landlord from exercising any of the other rights and
remedies available to Landlord. In addition, each installment of Monthly Base
Rent and any other amount payable by Tenant to Landlord under this Lease which
shall not have been paid within seven (7) days after the same shall have become
due and payable shall bear interest at the Interest Rate from the date that the
same became due and payable until paid, whether or not any demand shall be made
therefor.

                  Section 15.4. LEASE CONTINUES UNTIL TERMINATION. In the event
of a default by Tenant, this Lease shall continue in effect for so long as
Landlord shall not terminate Tenant's right to possession, and Landlord may
enforce all its rights and remedies under this Lease, including the right to
recover the rent as it becomes due under this Lease. Acts of maintenance or
preservation or efforts to relet the Premises or the appointment of a receiver
upon initiative of Landlord to protect Landlord's interest under this Lease
shall not constitute a termination of Tenant's right to possession.

                  Section 15.5. RELETTING PREMISES. In the event of a default by
Tenant, Landlord, at Landlord's election, may re-enter the Premises and, without
terminating this Lease, at any time and from time to time, relet the Premises or
any portion thereof for the account and in the name of Tenant. Landlord, at
Landlord's election, may eject Tenant or any of Tenant's assignees, sublessees
or any other person claiming any right in or through this Lease. Tenant shall
nevertheless pay to Landlord on the dates specified in this Lease all amounts
payable by Tenant to Landlord under this Lease, plus Landlord's costs and
expenses in connection therewith, less the proceeds of any sublease or
reletting. No act by or on behalf of Landlord under this Section shall
constitute a termination of this Lease unless Landlord gives Tenant written
notice of termination as provided in Section 15.2. Notwithstanding any prior
reletting without termination, Landlord may later elect to terminate this Lease
by reason of such default by Tenant.


                                   31
<PAGE>

                  Section 15.6. CURE BY LANDLORD. If Tenant shall fail to pay
any amount payable by Tenant to Landlord hereunder or shall fail to perform any
other covenant, agreement or obligation of Tenant hereunder and such failure
shall continue for thirty (30) days after notice thereof by Landlord, then
Landlord may, but shall not be obligated to, and without waiving or releasing
Tenant from any obligation, make any such payment or perform any such covenant,
agreement or obligation on Tenant's behalf. All sums so paid by Landlord and all
costs incurred by Landlord in taking such action shall be paid to Landlord on
demand, together with interest thereon at the Interest Rate until the date of
payment. In addition to all other rights and remedies of Landlord, Landlord
shall have the same rights and remedies in the event of the non-payment thereof
by Tenant as in the case of default by Tenant in the payment of rent.

                  Section 15.7. LANDLORD'S DEFAULT. In no event shall Landlord
be deemed to be in default under this Lease unless and until Landlord shall have
defaulted in the performance of its obligations under this Lease and Tenant
shall have given Landlord written notice of the default and, within a reasonable
period of time following Landlord's receipt of such notice, but in no event less
than thirty (30) days nor more than forty-five (45) days following Landlord's
receipt of such notice, Landlord shall not commence diligently to prosecute the
cure of such default to completion. In the event of any alleged default on the
part of Landlord under this Lease, Tenant shall give notice by registered mail
to any beneficiary or mortgagee under a deed of trust or mortgage encumbering
the Premises whose address shall have been furnished to Tenant, and shall offer
such beneficiary or mortgagee a reasonable opportunity to cure the default,
including time to obtain possession of the Premises by power of sale or judicial
foreclosure, if such shall be necessary to effect a cure.

                  Section 15.8      REMEDIES CUMULATIVE. The remedies provided
for in this Lease are in addition to any other remedies available to Landlord at
law or in equity by statute or otherwise.

                  Section 15.9.     SECURITY DEPOSIT.

                  (a)      Concurrently with Tenant's execution of this Lease,
Tenant shall deliver to Landlord an unconditional, irrevocable, transferable
letter of credit in the stated amount of Six Hundred Seventy-Six Thousand One
Hundred Dollars ($676,100) issued by a bank approved by Landlord in favor of
Landlord as beneficiary, for the term provided for below and otherwise in form
and substance satisfactory to Landlord ("Letter of Credit"). The Letter of
Credit shall be issued for an initial term of one year following the date of
this Lease, and Tenant shall cause the Letter of Credit to be renewed for
successive twelve-month periods throughout the Term not less than thirty (30)
days prior to each expiration date of the Letter of Credit, until Tenant shall
have the right to reduce the amount of the Letter of Credit as provided in
subparagraph (b) below. The Letter of Credit shall entitle Landlord to draw the
entire stated amount thereof upon presentation of


                                   32
<PAGE>

a sight draft in the amount of the draw. The Letter of Credit shall be held by
Landlord as security for the faithful performance by Tenant of all of the
covenants, agreements and obligations under this Lease to be performed by Tenant
during the Term. If Tenant shall fail to pay Monthly Base Rental or other
amounts payable by Tenant to Landlord under this Lease, or if Tenant shall
otherwise default with respect to any provision of this Lease after the
expiration of any applicable cure period, Landlord shall have the right, but
shall not be obligated, to draw the entire stated amount of the Letter of Credit
and to hold the proceeds thereof as a cash security deposit ("Security
Deposit"), and to use, apply or retain all or any portion of the Security
Deposit for the payment of rental or any other amount which Landlord may expend
or become obligated to expend by reason of Tenant's default, or to compensate
Landlord for any other loss or damage which Landlord may suffer by reason of
Tenant's default. If Landlord shall make any draw upon the Letter of Credit and
apply such draw to the cure of any default, Tenant shall, within ten (10) days
after Landlord's written demand therefor, deposit with Landlord a replacement,
additional or amended Letter or Letters of Credit in the same form (including
total stated amount and issuer) as the Letter of Credit drawn upon by Landlord.
If Landlord shall so use or apply any portion of any cash Security Deposit held
by Landlord. Tenant shall, within ten (10) days after Landlord's written demand
therefor, deposit cash with Landlord in the amount so used or applied by
Landlord. Landlord shall not be required to keep any Security Deposit separate
from Landlord's other funds, and Tenant shall not be entitled to any interest on
any Security Deposit. Landlord shall return the Letter of Credit, any Security
Deposit, and/or any balance thereof not applied in accordance with the
provisions of this Lease, to Tenant within thirty (30) days following the
expiration of this Lease and after Tenant has surrendered the Premises to
Landlord in the condition required under this Lease. In the event that Landlord
shall transfer its interest in the Premises, Landlord shall transfer the Letter
of Credit (to the extent transferable) and/or any funds then held by Landlord on
account of any cash Security Deposit to Landlord's transferee, and Landlord
shall thereupon be released from all liability to Tenant for return of the
Letter of Credit and/or cash Security Deposit.

                  (b)      If a default by Tenant under this Lease after the
expiration of any applicable cure period shall not have occurred at any time
prior to such time, effective not earlier than the first day of the fourth year
of the Term, Tenant shall have the right to cause the stated amount of the
Letter of Credit to be reduced to Three Hundred Forty-Two Thousand Two Hundred
Dollars ($338,100) by delivering to Landlord an amendment to the Letter of
Credit then held by Landlord acceptable to Landlord, or by delivering to
Landlord a new Letter of Credit in such lesser stated amount, but otherwise in
the same form as the Letter of Credit then held by Landlord. Such Letter of
Credit, and any amounts drawn thereunder, shall otherwise be held by Landlord on
all of the terms and provisions of subparagraph (a) above.

                           ARTICLE 16 - SUBORDINATION

                  Section 16.1. SUBORDINATION OF LEASE. This Lease shall be
subject and subordinate at all times to the lien of all mortgages and deeds of
trust in any amount or amounts whatsoever (including all advances thereunder,
renewals, replacement, modifications, supplements, and extensions thereof) now
or hereafter placed on or against the Premises, the Building or the Project, or
on or against Landlord's interest or estate therein, all without the necessity
of having further instruments executed on the part of Tenant to effectuate such
subordination. Tenant agrees to execute and deliver upon demand such further
instruments evidencing such subordination of this Lease to the lien of any such
mortgages or deeds of trust as may be required by Landlord, provided that each
mortgagee or beneficiary under any such mortgage or deed of trust, or purchaser
or grantee in respect thereof, shall agree, in a commercially reasonable
non-disturbance agreement, not to terminate or disturb Tenant's possession of
the Premises under this Lease in the event of termination of such ground or
underlying lease or foreclosure of such mortgage or deed of trust or deed in
lieu thereof, as the case may be, so long as Tenant is not in default under this
Lease beyond any applicable cure period under this Lease. In the event of the
foreclosure of any mortgage or deed of trust encumbering the Premises, the
Building or the Project, or on or against Landlord's estate or interest therein,
or in the event of a deed-in-lieu of foreclosure thereof, Tenant shall be bound
to any such mortgagee or beneficiary under any such mortgage or deed of trust,
or any other purchaser or grantee in foreclosure or under a deed-in-lieu
thereof, and Tenant hereby attorns to any such party as its landlord, such
attornment to be effective and self-operative without the execution of any
further instrument immediately upon such party's succeeding to Landlord's
interest under this Lease.

                  Section 16.2. SUBORDINATION OF DEED OF TRUST. Notwithstanding
anything to the contrary set forth above, any mortgagee or beneficiary under any
mortgage or deed of trust may at any time subordinate its mortgage or deed of
trust to this Lease in whole or in part, without Tenant's consent, by execution
of a written document subordinating such mortgage or deed of trust to this Lease
to the extent set forth in such document, and thereupon this Lease shall be
deemed prior to such mortgage or deed of trust to the extent set forth in such
document without regard to their respective dates of execution, delivery and/or
recording. In that event, to the extent set forth in such document, such
mortgage or deed of trust shall have the same rights with respect to this Lease
as would have existed if this Lease had been executed, and a memorandum thereof
recorded, prior to the execution, deliver and recording of the mortgage or deed
of trust.

                  Section 16.3. APPROVAL BY MORTGAGEES. Tenant hereby
acknowledges that the provisions of this Lease may be subject to the approval of
any lender that may hereafter make a loan secured by a mortgage or deed of trust
on the Premises, the Building or the Project. If such lender shall require, as a
condition to such financing, any modifications of this Lease in order to protect
the security of such mortgage or deed of


                                   34
<PAGE>

trust, at Landlord's request, Tenant agrees to execute appropriate amendments to
this Lease to effect such modifications; provided, however, that no such
modification shall change the size, location or dimension of the Premises or
increase the amount of the rent or other amounts payable by Tenant under this
Lease or otherwise materially, adversely affects any of Tenant's rights or
obligations under this Lease.

                         ARTICLE 17 - ENTRY BY LANDLORD

                  Landlord shall have the right to enter the Premises at
reasonable hours and after reasonable notice (except in the event of an
emergency in which event no notice shall be required) to: (a) inspect the
Premises; (b) exhibit the same to prospective purchasers, lenders or tenants;
(c) determine whether Tenant is complying with all of its obligations hereunder;
(d) provide any service to be provided by Landlord to Tenant hereunder; (e) post
notices of non-responsibility and "for sale" and "for lease" signs; and (f) make
repairs required of Landlord under the terms hereof or make repairs to any
adjoining space or make repairs, alterations or improvements to any other
portion of the Building or the Project. Tenant hereby waives any claim for
damages for any injury or inconvenience to or interference with Tenant's
business, any loss of occupancy or quiet enjoyment of the Premises, and any
other loss occasioned by such entry, provided that Landlord takes reasonable
steps to minimize the interference with Tenant's use and enjoyment of the
Premises. Landlord shall at all times have and retain a key with which to unlock
all of the doors in, on or about the Premises (excluding Tenant's vaults, safes
and similar areas agreed upon in writing by Tenant and Landlord prior to the
date of execution of this Lease by the parties). Landlord shall have the right
to use any and all means which Landlord may deem appropriate to open such doors
in an emergency in order to obtain entry to the Premises, and no entry to the
Premises obtained by Landlord by any of such means shall under any circumstance
be construed or deemed to be a forcible or unlawful entry into, or a detainer
of, the Premises or an eviction, actual or constructive, of Tenant from the
Premises, or any portion thereof.

                       ARTICLE 18 - OPTION TO EXTEND TERM

                  Section 18.1. OPTION. Subject to the provisions of Section
18.2 below, Landlord hereby grants to Tenant the option to extend the Term
hereof for one (1) additional five (5) year period ("Option Term") following
expiration of the initial Term specified in the Basic Lease Information
("Initial Term"), on all of the terms and conditions contained herein, except
that Monthly Base Rent shall be as provided below and that Tenant shall have no
further option to extend the Term. Tenant shall have the right to exercise the
such option by giving written notice of exercise of the option ("Option Notice")
to Landlord not less than twelve (12) months prior to the expiration of the
Initial Term. Notwithstanding the foregoing, if Tenant shall be in default under
this Lease beyond all applicable cure periods on the date of giving the Option
Notice, Tenant shall have no right to extend the Term and, at Landlord's option,
this Lease shall expire at the end of the Initial Term; and if Tenant shall be
in default under this Lease beyond all


                                   35
<PAGE>

applicable cure periods on the date the Option Term is to commence, the Option
Term shall not commence and, at Landlord's option, this Lease shall expire at
the end of the Initial Term. The Monthly Base Rent for the Option Term shall be
equal to the Fair Market Rental (as hereinafter defined) of the Premises at the
commencement of the Option Term. As used in this Lease, the word "Term" shall
mean the Term as the same may be extended pursuant to the provisions of this
Article 18, as applicable.

                  Section 18.2. LANDLORD'S USE. Notwithstanding the provisions
of Section 18.1 above, if Landlord or any affiliate of Landlord shall require
the use of the Premises at any time subsequent to the Initial Term for its own
occupancy, then Tenant shall not have the right to extend the Term of this Lease
for the Option Term, and the Term of this Lease shall expire at the end of the
Initial Term. If Landlord or any affiliate of Landlord shall so require the use
of the Premises, Landlord shall give to Tenant written notice of such fact not
later than fifteen (15) months prior to the end of the Initial Term.

                  Section 18.3. FAIR MARKET RENTAL.

                  (a)      "Fair Market Rental" shall mean the monthly full
service rental being charged for comparable space in comparable office buildings
in the Menlo Park/Palo Alto, California area as of the date of commencement of
the Option Term, with similar amenities, taking into consideration the size,
location, proposed term of the lease, extent of services to be provided, the
time that the particular rate under consideration became or is to become
effective, and other relevant factors; provided, however, that Monthly Base Rent
shall in no event be less than the Monthly Base Rent which was in effect
immediately prior to the date of commencement of the Option Term. Within thirty
(30) days following receipt of the Option Notice, Landlord shall give to Tenant
written notice of Landlord's estimation of Fair Market Rental. If Tenant shall
not agree with such estimation of Fair Market Rental, Landlord and Tenant shall
negotiate in good faith to agree upon the Fair Market Rental for a period of
forty-five (45) days following the date of Landlord's notice to Tenant. If
Landlord and Tenant shall be unable to agree upon the Fair Market Rental within
such period of time, Fair Market Rental shall be determined pursuant to the
arbitration procedure set forth in this Article 18. In the event that such
arbitration not have been concluded prior to the date of commencement of the
Option Term, Tenant shall continue to pay as Monthly Base Rent hereunder, until
the Fair Market Rental has been determined by arbitration, the Monthly Base Rent
payable with respect to the month immediately preceding the commencement of the
Option Term. After the Fair Market Rental has been determined by arbitration,
then any adjustment required to adjust the amount previously paid shall be made
by payment by Tenant to Landlord within ten (10) days after such determination
of Fair Market Rental

                  (b)      In the event that Landlord and Tenant shall be unable
to agree upon Fair Market Rental within the period of time specified in
subparagraph (a) above, within ten (10) days thereafter, each of the parties
shall select a commercial real estate broker


                                   36
<PAGE>

from a recognized real estate brokerage firm having offices in Palo Alto or San
Jose, California, who has at least five (5) years' full-time commercial real
estate brokerage experience and who is familiar with the Fair Market Rental of
commercial office space in comparable office buildings in Menlo Park/Palo Alto,
California area, and shall give written notice of such selection to the other
party specifying therein the name and address of the person to act as the
arbitrator on such party's behalf. If either party shall fail to notify the
other party of its appointment of a broker having such qualifications within or
by the time specified, then the broker appointed by the other party shall make
the sole determination of Fair Market Rental of the Premises, and such
determination shall be binding upon the parties.

                  (c)      The Fair Market Rental shall be determined by the two
brokers appointed by the parties in accordance with the following procedures.
Within thirty (30) days following the appointment of the brokers by the parties,
each of the brokers shall state in writing his determination of the Fair Market
Rental supported by the reasons therefor and shall provide copies to each party.
If such determinations do not differ by more than ten percent (10%), the Fair
Market Rental shall be the average of the two determinations. If such
determinations differ by more than ten percent (10%) and the two brokers are
subsequently unable to agree upon the Fair Market Rental, the two brokers shall
appoint a third broker, who shall be a competent and impartial person with
qualifications similar to those required of the first two brokers. If the two
brokers are unable to agree upon such appointment within ten (10) days following
their determinations of Fair Market Rental, then either Landlord or Tenant, on
behalf of both parties, may request appointment of such a qualified person by
the Presiding Judge of the San Mateo County Superior Court acting in his
individual capacity. Following appointment of the third broker, he shall
promptly make his determination of Fair Market Rental in the manner provided
above, and the average of the three determinations shall constitute the Fair
Market Rental. If, however, the low determination of Fair Market Rental and/or
the high determination of Fair Market Rental are more than ten percent (10%)
lower and/or higher than the middle determination, any such low determination
and/or high determination shall be disregarded. If only one determination is
more than ten percent (10%) above or below the middle determination, such that
only one determination needs to be disregarded, the remaining two determinations
shall be added together and their total divided by two; the resulting quotient
shall be the Fair Market Rental. If both the low determination and the high
determination are disregarded, then the middle determination shall establish the
Monthly Base Rent for the Premises for the Option Term and shall be final and
binding upon the parties.

                  (d)      In the event of a failure, refusal or inability of
any broker to act, his successor shall be appointed by him, but in the case of
the third broker, his successor shall be appointed in the same manner as that
set forth herein with respect to the appointment of the original third broker.
The brokers shall make the final determination of Fair Market Rental not later
than sixty (60) days prior to the commencement of the


                                   37
<PAGE>

Option Term. Each party shall pay the fees and expenses of its respective broker
and both shall pay one-half (1/2) of the fees and expenses of the third broker.
Attorneys' fees and expenses of counsel shall be paid by the respective party
engaging such counsel.

                           ARTICLE 19 - MISCELLANEOUS

                  Section 19.1. HOLDING OVER. If Tenant shall remain in
possession of the Premises after the expiration or earlier termination of this
Lease with the written consent of Landlord, such occupancy shall be a tenancy
from month-to-month and all of the terms, covenants and agreements hereof shall
otherwise continue to apply and bind Tenant so long as Tenant shall remain in
possession, except that the Monthly Base Rent shall be one hundred fifty percent
(150%) of the Monthly Base Rent payable for the last month of the Term, prorated
on a daily basis for each day that Tenant remains in possession. If Tenant shall
remain in possession of the Premises after the expiration or earlier termination
of this Lease without the written consent of Landlord, Tenant shall indemnify,
defend and hold Landlord harmless against any and all claims, losses and
liabilities for damages resulting from failure to surrender possession,
including, without limitation, any claims made by any succeeding tenant.

                  Section 19.2. LANDLORD'S INTEREST. The term "Landlord" as used
herein shall mean only the owner or owners at the times in question of fee title
to the Premises. In the event of a sale, conveyance or assignment by Landlord of
Landlord's interest in the Premises, the Building or the Project, Landlord shall
be relieved, from and after the date of such sale, conveyance or assignment, of
any liability thereafter accruing upon any of the agreements, obligations or
covenants of Landlord under the Lease, and for such future period Tenant agrees
to look solely to the successor-in-interest of Landlord in and to this Lease,
provided that any funds in the hands of Landlord, in which Tenant has an
interest, shall be delivered to such successor-in-interest. This Lease shall not
be affected by any such sale, conveyance, or assignment, however, and Tenant
agrees to attorn to the purchaser or assignee, such attornment to be effective
and self-operative without the execution of any further instruments on the part
of any of the parties to this Lease.

                  Section 19.3. QUIET ENJOYMENT. Landlord hereby covenants in
favor of Tenant that, provided that Tenant shall pay all rent and perform all
other covenants, agreements and obligations of Tenant under this Lease, Tenant
shall have and enjoy quiet possession of the Premises throughout the Term
without any hindrance or interruption by Landlord or any person lawfully
claiming by, through or under Landlord, subject to the terms and conditions of
this Lease and any mortgage or deed of trust to which this Lease is subject and
subordinate.

                  Section 19.4. LANDLORD'S LIABILITY. The liability of Landlord
under this Lease or otherwise in connection with the Premises or the Building
shall be limited to Landlord's interest in the Project, and in no event shall
any other assets of Landlord or


                                   38
<PAGE>

any assets of any constituent partner or member of Landlord be subject to any
liability arising out of or in connection with this Lease, the Premises, the
Building or the Project.

                  Section 19.5. NO MERGER. The voluntary or other surrender of
this Lease by Tenant, or a mutual cancellation thereof, shall not work a merger,
and shall, at the option of Landlord, either terminate any or all existing
subleases or operate as an assignment to Landlord of any or all of such
subleases.

                  Section 19.6. SURRENDER OF PREMISES. At the expiration of the
Term or upon earlier termination of this Lease, Tenant shall surrender to
Landlord possession of the Premises, in the same condition as received,
reasonable wear and tear excepted. Tenant shall have the right to remove from
the Premises any of Tenant's movable partitions, trade fixtures, furnishings,
fixtures or equipment which may be removed without causing damage to the
Premises, and shall remove any Alterations and any other alterations, additions
or improvements, trade fixtures, equipment or furnishings which Landlord shall
have directed to be removed, and shall promptly repair any damage to the
Premises caused by such removal. Any personal property of Tenant not removed
from the Premises shall, to the extent permitted by law, be deemed to have been
abandoned by Tenant and shall thereupon become the property of Landlord.

                  Section 19.7. ESTOPPEL CERTIFICATE. At any time and from time
to time, but in no event later than ten (10) days' following a request therefor
by Landlord, Tenant shall execute, acknowledge and deliver to Landlord, a
certificate certifying: (a) that Tenant has accepted the Premises (or, if Tenant
has not done so, that Tenant has not accepted the Premises, and specifying the
reasons therefor); (b) the commencement and expiration dates of this Lease; (c)
whether there are then existing any defaults by Tenant or Landlord in the
performance of its obligations under this Lease (and, if so, specifying the
same); (d) that this Lease is unmodified and in full force and effect (or, if
there have been modifications, that this Lease is in full force and effect, as
modified, and stating the date and nature of each modification); (e) the
capacity of the person executing such certificate, and that such person is duly
authorized to execute the same on behalf of Tenant; (f) the date, if any, to
which rent and other sums payable hereunder have been paid; (g) that no notice
has been received by Tenant of any default which has not been cured, except as
to defaults specified in the certificate; (h) the amount of any security deposit
and prepaid rent; and (i) such other matters as Landlord may request. Any such
certificate may be relied upon by any prospective purchaser of, or any existing
or prospective mortgagee or beneficiary under any deed of trust affecting, the
Building, the Project or any part thereof.

                  Section 19.8. NO LIGHT, AIR OR VIEW EASEMENT. Nothing
contained in this Lease shall grant to or confer upon Tenant any right to
receive any particular amount or level of light, air or view from the Premises.
Any diminution in or shutting off of light, air or view by any structure which
is now or may hereafter be erected in the Project


                                   39
<PAGE>

or on other lands adjacent to the Building shall in no way affect this Lease or
impose any liability upon Landlord. Noise, dust or vibration or other incidents
to new construction of improvements on lands adjacent to the Building, whether
or not owned by Landlord, shall in no way affect this Lease or impose any
liability on Landlord.

                  Section 19.9. NOTICES. All notices and other communications
which may or are required or permitted to be given by either party to the other
hereunder shall be in writing and shall be deemed to have been given upon
receipt or refusal of receipt, when personally delivered or transmitted by
private nationally recognized overnight courier service, or by deposit in the
United States mail, certified or registered, with return receipt requested,
postage prepaid, and addressed as follows: prior to the date on which Tenant
accepts possession of the Premises, at Tenant's address prior to occupancy set
out in the Basic Lease Information, and thereafter to Tenant at the Premises, or
to such other place as Tenant may from time to time designate in a written
notice to Landlord; to Landlord at the address specified in the Basic Lease
Information, or to such other place as Landlord may from time to time designate
in a written notice to Tenant.

                  Section 19.10. SUCCESSORS. Subject to the provisions of
Article 10 of this Lease, all of the terms, covenants and conditions contained
in this Lease shall be binding upon, and shall inure to the benefit of, the
heirs, executors, administrators, successors and assigns of the parties hereto.

                  Section 19.11. ATTORNEYS' FEES. In the event of any action or
proceeding brought by either party against the other under this Lease, the
prevailing party shall be entitled to recover court costs and the fees of its
attorneys in such action or proceeding (whether at the administrative, trial or
appellate levels) in such amount as the court or administrative body may award.

                  Section 19.12. WAIVER. The failure of Landlord or Tenant to
exercise their respective rights in connection with any breach by Tenant or
Landlord, as applicable, of any provision of this Lease shall not be deemed to
be a waiver of such provision or any subsequent breach or violation of the same
or any other provision of this Lease. The subsequent acceptance of rent
hereunder by Landlord shall not be deemed to be a waiver of any preceding breach
or violation by Tenant of any provision of this Lease other than the failure of
Tenant to pay the particular rent so accepted, regardless of Landlord's
knowledge of such preceding breach or violation at the time of acceptance of
such rent.

                  Section 19.13. CAPTIONS. The captions and headings of the
Articles and Sections in this Lease are for convenience only and shall not in
any way limit or be deemed to construe or interpret the terms and provisions of
this Lease.

                  Section  19.14.  TIME OF ESSENCE.  Time is of the essence of
this Lease and of all provisions hereof, except as otherwise provided herein.

<PAGE>

                  Section 19.15. INTEREST RATE. As used herein, the term
"Interest Rate" shall mean a per annum rate of interest equal to three percent
(3%) plus the rate most recently announced by Wells Fargo Bank, N.A., at its
main office in San Francisco, California, as its "Prime Rate", serving as the
basis upon which effective rates of interest are calculated for those loans
making reference thereto, but in no event in excess of the maximum applicable
usury limitation.

                  Section  19.16.  GOVERNING  LAW. This Lease shall be governed
by, and construed and enforced in accordance with, the laws of the State of

intended by the parties as a final expression of their agreement with respect to
such terms as are included in this Lease and shall supersede any prior
agreements, memoranda or other written communications regarding this Lease. The
parties further intend that this Lease constitutes the complete and exclusive
statement of its terms and that no extrinsic evidence whatsoever may be
introduced in any judicial proceedings, if any, involving this Lease.

                  Section 19.18. INVALIDITY. If any provision of this Lease or
the application thereof to any person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Lease, or the application of
such provision to persons or circumstances other than those as to which it is

this Lease shall be valid and be enforceable to the full extent permitted by
law.

corporation, a partnership or limited liability company, each of the persons
executing this Lease on behalf of Tenant does hereby covenant and warrant that
Tenant is a duly authorized and existing entity, that Tenant has full right and
authority to enter into this Lease, and that each and all of the persons on
behalf of Tenant are authorized to do so. Upon Landlord's request, Tenant shall
provide Landlord with evidence reasonably satisfactory to Landlord confirming
the foregoing covenants and warranties.

                  Section 19.20. NO OFFER. No contractual or other rights shall
exist between Landlord and Tenant with respect to the Premises until both have
executed and delivered this Lease, notwithstanding that Landlord has delivered
to Tenant an unexecuted copy of this Lease. The submission of this Lease to
Tenant shall not constitute the grant of an option for the Tenant to lease, or
otherwise create any interest by Tenant in, the Premises or any other premises
in the Building or Project. The execution of this Lease by Tenant and return to
Landlord shall not be binding upon Landlord, notwithstanding any time interval,
until Landlord has in fact executed and delivered this Lease to Tenant.

damages, liabilities or causes of action (including attorney's fees) arising out
of or relating to any breach of the foregoing representation and warranty or
arising out of or relating to any claim made by any broker, finder or
salesperson claiming to have dealt with the indemnifying party.

to place a sign identifying Tenant's occupancy of the Premises on the existing

which consent shall not be unreasonably withheld by Landlord. All signs so
consented to by Landlord and placed by Tenant on any monument sign for the
Building or upon or in the Building or Premises shall be fabricated and
installed by Tenant at its sole cost and expense and shall comply in all
respects with size, design, lettering and material guidelines established from
time to time by Landlord for the Project. Landlord reserves the right to change
or alter such guidelines at such times and for such tenants as Landlord may
determine. Tenant shall comply with all applicable statutes, ordinances, rules
and regulations of governmental authorities with respect to any such signs.

                  Section 19.26. PARKING. Tenant, at no cost or expense to
Tenant, shall have the non-exclusive use of not more than One Hundred
Eighty-Four (184) of the parking spaces in the parking areas of the Project for
the parking of motor vehicles by Tenant's employees working on the Premises.
Landlord shall have the right to relocate such non-exclusive parking spaces from
time to time to other parking areas in or adjacent to the Project. Landlord
shall have no obligation to monitor or police the use of any parking areas or
otherwise to assure Tenant or its employees of the availability of any parking
spaces. Notwithstanding the foregoing, Landlord shall from time to time have


                                       42
<PAGE>

the right to institute and maintain procedures for controlling the use of the

such procedures instituted and maintained by Landlord from time to time.

                  Section 19.27. BUILDING ACCESS. Landlord shall provide Tenant
with Two Hundred Fifty (250) building access cards for the Building at a cost of
$10 per card. Tenant shall return all such building access cards to Landlord

volleyball court, basketball court, picnic tables and lawn area immediately
adjacent to the Premises, and (b) the cafeteria located in the Administration
Building of the Project during Landlord's hours of operation of the cafeteria

for Tenant's benefit, and Landlord shall have the right to change or reduce
Landlord's hours of operation of the cafeteria and to discontinue any cafeteria
service entirely, at Landlord's sole option.

                  Section 19.29. CONFERENCE ROOMS. Tenant shall have the
right to use the conference room on the first floor of the Administration
Building ("Conference Room") from time to time ("Use Periods") during the

availability of the Conference Room shall be subject to the prior right of
use by Landlord, its employees, agents or invitees and other tenants.

                  (b)      Tenant shall pay to Landlord, at the same time and in
the same manner as the payment of Monthly Base Rent, a charge calculated in
accordance with Section 7.3 above for each Use Period. Landlord shall cause the
Conference Room to be unoccupied and available for Tenant's use during the Use
Periods. At the end of each Use Period, Tenant shall leave the Conference Room
in the same condition as it was prior to such Use Period and shall remove

                                       43
<PAGE>

area located on the first floor of the Building and not included in the
Premises, and shall vacate such security and customer service area, such
security and customer service area shall thereupon become a part of the
Premises. Landlord and Tenant shall promptly execute and deliver an appropriate
amendment to this Lease providing for (a) incorporation of such security and
customer service area within the Premises; (b) Tenant's payment of Monthly Base
Rent with respect to such security and customer service area at the rental rate
then provided for under this Lease with respect to the balance of the Premises,
subject to such increases as are provided for under this Lease; (c) an
appropriate adjustment to Tenant's Share; and (d) such other reasonable terms
and provisions as Landlord and Tenant shall agree upon. In no event shall
Landlord be obligated to make any alterations, additions, improvements or
repairs to such security and customer service area, and Tenant shall accept
possession of such security and customer service area in its "as-is" condition.
The security and customer service area consists of 3,672 square feet of rentable
area.

                  (b)      At Tenant's request and upon Landlord's reasonable
approval, Landlord shall caused to be installed a demising wall or door

       the Second Delivery, the Initial System or the Expansion System (in the
       latter case, applicable only when the Purchaser exercises the Option)
       shall, if already paid by the Purchaser, be refunded in accordance with
       Clause 8.3 and such refunds shall be calculated according to the
       following percentages, or if not yet paid by the Purchaser, shall be
       deducted by the following percentages:-

       (a)    5%, if the Achievement Time is delayed by one month or part
              thereof; or
       (b)    6%, if the Achievement Time is delayed by two months or part
              thereof; or
       (c)    7%, if the Achievement Time is delayed by three months or part
              thereof.

       PROVIDED ALWAYS that the time for achievement of a Milestone may be
       extended to the extent reasonable if that Milestone has not been achieved
       by reason of a breach of this Agreement caused solely by the Purchaser,
       provided further that in each case the Contractor has notified the
       Purchaser in writing specifying reasonable particulars of the alleged
       breach within fourteen (14) days after it becomes aware of the relevant
       event or breach.

4.2    The Parties recognise and agree that the sums provided in Clause 4.1 are
       reasonable pre-estimates of the damage which may occur to the Purchaser
       taking into account all the relevant information available at the time of
       signature of this Agreement and that such sums are liquidated damages and
       in no way to be considered as penalties.

<PAGE>

4.3    Nothing in this Clause shall be construed as limiting the right of the
       Purchaser to terminate this Agreement in whole or in part in accordance
       with any provision of this Agreement or at law as a consequence of such
       late delivery or completion.


5.     INSPECTION AND ACCEPTANCE

5.1    Those elements of the Initial Acceptance Tests to be carried out at the
       Contractor's facilities shall be undertaken by the Contractor at least
       fourteen (14) days prior to  delivery of the Initial System and the
       Expansion System respectively.  The Contractor shall give to the
       Purchaser not less than seven (7) days notice in writing of the date and
       time on and at which the aforementioned Initial Acceptance Tests shall be
       performed and the Purchaser shall have the right to be present throughout

       of the tests, supply the test results of the aforementioned Initial
       Acceptance Tests to the Purchaser.

5.2    Those elements of the Initial Acceptance Tests to be carried out at the
       Site shall be undertaken by the Contractor within 10 days after receiving
       written notice from the Purchaser to carry out the same, such notice to
       be given by the Purchaser at least twenty-one (21) days before the
       anticipated commercial launch of the System as specified in the Proposed
       Delivery Schedule.  The Contractor shall give to the Purchaser not less
       than seven (7) days notice in writing of the date and time on and at

       the same. The Contractor shall within 7 days of completion of the test,
       supply the test results of the aforementioned Initial Acceptance Tests to
       the Purchaser.

5.3    Upon completion of the Initial Acceptance Test referred to in clause 5.2,
       the Purchaser shall notify the Contractor either:-

       (a)    of its acceptance of the Initial Acceptance Tests in which case
              Initial Acceptance of the Initial System or the Expansion System
              (in the latter case, only applicable when the Purchaser exercises
              the Option) shall have occurred upon the issuance of an Initial
              Acceptance Certificate; or

       (b)    of those particulars in respect of which the System does not fully
              comply with or perform in accordance with the Specifications and
              the Proposal, then upon remedy of such particulars and compliance
              of the System with the requirements of this Agreement, the
              Purchaser shall accept the Initial System or the Expansion System
              (in the latter case, only applicable when the Purchaser exercises
              the Option) whereupon an Initial Acceptance Certificate shall be
              issued.

       Both parties agree that upon the issuance of the Initial Acceptance
       Certificate, the Initial Acceptance shall be deemed to have occurred.

5.4    (a)    Service Acceptance means acceptance of the Initial System by the
              Purchaser when the Initial System and each and every feature
              thereof described in the Proposal, is compatible and integrated
              with every other item of the System and has operated in a
              technically and commercially acceptable manner to the

<PAGE>

              Purchaser for a consecutive period of ninety (90) days from date
              of connection of the Initial System to the GSM System; or

       (b)    Service Acceptance means acceptance of the Expansion System by the
              Purchaser when the Expansion System and each and every feature
              thereof described in the Proposal, is compatible and integrated
              with every other item of the System and has operated in a
              technically and commercially acceptable manner to the Purchaser
              for a consecutive period of ninety (90) days from date of
              connection of the Expansion System to the GSM System.

       The Purchaser shall issue a Service Acceptance Certificate to the
       Contractor upon the occurrence of Service Acceptance described at 5.4 (a)
       or 5.4 (b) above, as relevant.  Both parties agree that upon the issuance
       of the relevant Service Acceptance Certificate, the relevant Service
       Acceptance, shall be deemed to have occurred.

5.5    The Work may at any time and from time to time be inspected or evaluated
       by the Purchaser and the Purchaser shall notify the Contractor of those
       particulars in respect of which the Work does not fully conform to the
       requirements of this Agreement.

5.6    Remedy of any particulars referred to in this Clause 5 or repeat tests as
       required by the Purchaser shall be effected or undertaken by the
       Contractor at its cost, promptly upon receipt of notice by the Purchaser.
       If the Contractor fails to remedy any such particulars promptly, the
       Purchaser may elect to have any or all such particulars remedied through
       other means, in which event the Contractor shall pay all reasonable costs
       incurred by the Purchaser in so remedying such particular(s); provided
       that the Purchaser shall provide the Contractor with a written notice
       reasonably setting out the reasons that the Purchaser believes that the
       Contractor has failed to remedy such particulars.

5.7    Nothing in this Clause shall relieve the Contractor of its obligation to
       comply with the delivery schedule referred to in Appendix A hereof, nor
       limit the Purchaser's right to terminate this Agreement, in whole or in
       part, in accordance with other provisions of this Agreement or at law.

5.8    If, in relation to the First Delivery, the Second Delivery or the
       Expansion System, the Site is not ready for installation of the relevant
       Equipment within sixty (60) days of the Milestone date applicable to that
       delivery as specified in Appendix A:

       (i)    the Purchaser will be deemed to have accepted the Phase I
              Deployment or Phase II Deployment of the Initial System (or the
              Expansion System), as the case may be) and to have issued an
              Initial Acceptance Certificate in accordance with Clause 5.3(a) on
              the sixty first (61st) day after the applicable Milestone date (or
              the milestone set for delivery of the Equipment to be delivered
              under the Expansion) ; and

       (ii)   the Purchaser will be deemed to have accepted the Phase I
              Deployment or Phase II Deployment of the Initial System (or the

6.     TITLE AND ASSUMPTION OF RISK

6.1    The Contractor warrants to the Purchaser that it will deliver to the
       Purchaser good title to each and every item comprised in the Equipment
       and the rights to use the Software, free from any claim, lien, pledge,

       risk shall pass back to Contractor at the point of dispatch.

6.4    Title to and the rights in Software shall be in accordance with the
       provisions of Clause 10 below.


7.     WARRANTY OF THE WORK, EQUIPMENT, SOFTWARE AND SERVICES

7.1    Without limiting any other warranties or undertakings contained in this
       Agreement or implied by law, the Contractor warrants and undertakes that:

       (a)    each item of the System will in all respects conform to, perform
              in accordance with, have the features and otherwise meet the
              Proposal and Specifications;

       (b)    the System and each item of the Equipment and Software shall be
              properly and completely installed;

       (c)    all the Work to be provided hereunder shall conform in design,
              performance and materials to the requirements of this Agreement
              and shall be free from defects in design, material, performance or
              workmanship for the Warranty Period (however, defects which the
              Purchaser considers to be non substantial and

<PAGE>

              routine in the Software shall not be regarded as a breach of this
              Warranty) and be of the most suitable grade and quality for the
              purpose intended;

       (d)    all Services to be provided hereunder shall be performed in a
              skillful and workmanlike manner, both in accordance with the
              Proposal and all applicable Specifications and other requirements
              of this Agreement;

       (e)    each item of Equipment and Software comprised in the Initial
              System will be compatible and integrated with every other item of
              the System and the Expansion System will be compatible and
              integrated with the Initial System and the System;

       (f)    the Software will conform with the Contractor's then current
              published specifications when delivered and will represent the
              latest and most up to date version; and

       (g)    each item of Equipment and Software supplied by the Contractor
              will not infringe any patent, copyright, trade secrets or
              proprietary rights of the Purchaser and any third party.

       The above warranties ("the Warranties") shall continue to apply
       notwithstanding any acceptance of all or part of the Work, or payment by
       the Purchaser.

7.2    The Purchaser shall be entitled at any time during the Warranty Period
       and irrespective of prior inspections or acceptances, to reject any item
       of the Software or Equipment not conforming with any of the Warranties.
       During the Warranty Period the Contractor shall, at no cost to the
       Purchaser, make good and rectify such Equipment or Software or, at the
       Purchaser's option, the Contractor shall replace any item of Equipment or
       Software not conforming with the Warranties with conforming Equipment or
       Software.  Any Equipment or Software not conforming to any of the
       Warranties shall be repaired or replaced at the Site unless the
       Contractor is not reasonably able to do so in which case it shall be
       returned to the Contractor with risk passing as provided for in Clause
       7.5 hereof.  If the Contractor fails to correct or replace such defective
       Equipment promptly after notification and authorization from the
       Purchaser, the Purchaser may, by agreement or otherwise, correct or
       replace such defective Equipment and recover the cost thereof from the
       Contractor.  After notification of a defect to the Contractor, the
       Purchaser may elect not to require correction or replacement of such
       defective Equipment and, in such event, the Contractor, if required by
       the Purchaser, shall refund such portion of the price as is equitable in
       the circumstances as agreed between the parties or in default of
       agreement as determined under Clause 21.

7.3    The Warranties shall continue as to corrected or replaced items for the
       balance of the Warranty Period of the corrected or replaced item or for
       ninety (90) days after the date of acceptance by the Purchaser of the
       corrected or replaced items, whichever is longer.

7.4    Shipping, freight and insurance charges, in respect of warranty claims
       during the Warranty Period shall be met by the Contractor.  Such charges
       shall be prepaid by the Contractor or, it the Purchaser agrees, paid by
       the Purchaser on the Contractor's behalf in which case any such charges
       shall be reimbursed by the Contractor under Clause 8.3 or may (at the
       Purchaser's option) be set-off by the Purchaser under Clause 8.4.

<PAGE>

       In the event that the parties determine and agree that a warranty claim
       was incorrectly made, the Purchaser shall be liable for such charges in
       respect of that claim.

7.5    Any item replaced will, subject to Clause 7.3 hereof, be deemed to be on
       an exchange basis and the item provided to the Purchaser in exchange
       shall be the sole property of the Purchaser.  Title of the item to be
       replaced shall pass to Contractor on acceptance of the new item by the
       Purchaser.  Risk in the item to be replaced shall pass to Contractor at
       point of dispatch.  Title and risk of the replacement item shall pass to
       the Purchaser upon acceptance of that item.

7.6    The Contractor shall effect repair, correction or replacement of any
       defective item as soon as possible and in any event within thirty (30)
       days from receipt of the item at its facilities or, from the date of
       receipt of notice of defect if the Contractor repairs or replaces the
       defective item at the Site, save where the defect in the sole opinion of
       the Purchaser causes downtime or impacts the performance of the System in
       which case the repair or replacement must be provided in accordance with
       the procedures and time limits specified in the Customer Advocacy Plan.

7.7    Any dispute as to the applicability of any warranty claim shall be
       resolved in accordance with Clause 21 hereof.

7.8    The Contractor shall provide the facilities and services set out in the
       Customer Advocacy Plan. If the Purchaser so requires, the Contractor and
       the Purchaser shall enter into a Maintenance and Support Agreement, in
       the terms of the draft Maintenance and Support Agreement contained in
       Schedule 4. A manager shall be designated as being responsible to the
       Purchaser for provision of facilities and services to be provided under
       the Customer Advocacy Plan (and the Maintenance and Support Agreement, if
       the parties enter into the same). Such manager shall be designated as a
       "Key Person" in accordance with the terms of Clause 17.1 hereof and shall
       be provided with full representative authority to bind the Contractor in
       respect of any warranty claim made by the Purchaser.

7.9    During an emergency, the repair of Equipment or any specific work must be
       performed by qualified staff of the Purchaser, who have undertaken the
       training organized by the Contractor.  The Purchaser shall inform the
       Contractor the details of fault and repair in writing, within 24 hours
       after emergency repair and any work so performed by the Purchaser's staff
       shall not invalidate any Warranties provided reasonable care is taken
       during such repair.

              associations, and in terms approved, in both cases, by the
              Purchaser (which approval shall not be unreasonably withheld) and
              for this purpose the Contractor shall submit to the Purchaser at
              least fourteen (14) days prior to the date for commencement of any
              works under this Agreement the identity of insurers or protection
              and indemnity associations and the terms of such insurances.
              Thereafter the Contractor shall whenever required produce to the
              Purchaser a certificate of insurance and proof of payment of the
              current premiums.  In addition to such certificate of insurance,
              the Contractor shall notify the Purchaser of all policy exclusions
              and conditions which could affect the rights of the Purchaser.
              Provided always that, subject to 16.2 (c), the approval of the
              Purchaser as aforesaid to all insurance which the Contractor is
              obliged to effect shall be a condition precedent to the Contractor
              being given possession of the Site under this Agreement, but shall
              not, for the avoidance of doubt, delay the date for commencement
              of the works pursuant to this Agreement.

       (b)    The Contractor shall bear the cost of all excesses, exclusions and
              limitations applying under all insurance policies, in so far as
              they concern risks for which he is responsible under the terms of
              this Agreement.  In the event of any claims under the insurances,
              any cost that may be incurred by the Purchaser in respect of the
              excesses shall be recoverable from the Contractor by the Purchaser
              as a debt or may be deducted by the Purchaser from any monies due
              or to become due to the Contractor under this Agreement.

       (c)    If the Contractor shall fail upon request to produce to the
              Purchaser satisfactory evidence that there is in force the
              insurance referred to in this Clause 16 or any other insurance
              which he may be required to effect the terms of this Agreement
              then and in any such case the Purchaser may, without prejudice to
              the Purchaser's right to reclaim from the Contractor any premiums
              paid by the Purchaser from the Contractor, give possession of Site

<PAGE>

              to the Contractor to commence works and effect and keep in force
              any such insurance and pay such premium or premiums as may be
              necessary for that purpose and from time to time deduct the amount
              so paid by the Purchaser as aforesaid from any monies due or which
              may become due to the Contractor or recover the same as a debt due
              from the Contractor.

       (d)    Without prejudice to the other provisions of this Clause 16, the
              Contractor shall ensure and shall cause any sub-contractor of any
              tier to ensure that the interest of the Purchaser is endorsed on
              any policy of insurance which provides cover in relation to any of
              the contractor's liabilities under this Agreement.

       (e)    The Contractor shall promptly supply to underwriters and/or
              insurers all documentation and information which they may
              reasonably require to effect and maintain the insurance referred
              to in this Clause 16.

       (f)    The Contractor shall at all times take all necessary precautions
              to prevent loss or damage to the Works or any part thereof and the
              Contractor shall not do anything or cause or permit any of its
              sub-contractors to do anything, whether on or off the Site, which
              would or might, render voidable any policy of insurance required
              by this Agreement.

              endorsed to cover the Purchaser's liability to employees of the

              indemnity but any extra premium shall be at his own expense.

       (c)    The insurance policy shall include a cross liability clause such

       with a proposed schedule of all alterations which would need to be made
       to the terms and conditions of this Agreement and, if applicable, the

       Specifications for the purposes of this Clause 18.

       is submitted within forty-five (45) days of the date of receipt by the
       Purchaser or the Contractor, as the case may be, of the change proposal
       referred to in paragraph 17.1 hereof.

18.4   If the parties fail to reach agreement on the adjustment of the fixed
       prices, the adjustment shall be determined in accordance with Clause 21
       hereof.  Nothing in this paragraph shall relieve the Contractor of its
       obligation to proceed promptly with the implementation of the directed
       change pursuant to paragraph 18 hereof or with the provision to the
       Purchaser of any Work under this Agreement, as changed.

       holiday in the country in which the particular contractual performance

<PAGE>

       ten (10) days after such event has occurred.

23.3   Upon the occurrence of Force Majeure, and with proper notice as set forth
       above the time-limit for performance shall be extended accordingly,
       provided that the party wishing to rely upon the Force Majeure event
       makes every effort to minimize such delay.  If the delay continues beyond
       a reasonable period, taking into account the requirements of the
       Purchaser for the delayed Equipment or Services or prompt performance of

              completion within the time specified in this Agreement or fails to
              complete the Work within such time and fails to remedy such

              with detailed elaboration of each feature as below:


4.1.4.1 SMS CELL BROADCAST

              This SMS Cell Broadcast service is analogous to the teletext
              service. It permits a number of unacknowledged general messages to
              be broadcast to all receivers within a particular region. SMSCB
              messages are broadcast to defined geographical areas known as cell
              broadcast areas. These areas may comprise of one or more cells, or
              may comprise the entire PLMN.

              It provides SMS Cell Broadcast capability as defined GSM
              Specification 03.41. It's capabilities and benefits are:

              -      Ability to enter, delete, modify and schedule cell
                     broadcast messages from the OMC.

              -      Supports Background and Normal Messages.

              -      Allows operator to offer specialized services.

              -      Using cell broadcast message it may be possible to indicate
                     on a subscriber's MS whether he is using the in-building
                     network or the PLMN.


4.1.4.2 SETTABLE HANDOVER MARGIN BY CELL

              There are two main types of radio based handover processing
              defined in GSM, namely Rescue and Confinement. Rescue handover is
              performed based on preprocessing RF measurement data collected in
              the uplink and downlink. Both the signal level and quality, and MS
              distance together with the settings of O&M parameters are
              considered to determine the necessity of handover and to evaluate
              the target candidate cell list. Similarly, confinement handover
              decision is made by comparing the computed power budget values
              with a set of O&M thresholds. The

<PAGE>

              feature O&M parameters are introduced to allow greater flexibility
              for the operator to control over the handover decision making
              process.

              It provides the ability to set handover margins on a per cell
              basis. It's capabilities and benefits are:

              -      The settable parameters are Power Budget, RX level and
                     Quality.

              -      Provides greater flexibility to operator to control the
                     handover decision making process.


4.1.4.3 DTX DOWNLINK

              It provides DTX downlink support in addition to existing uplink
              support as defined in GSM Specification 06.31. It's capabilities
              and benefits are:

              -      DTX downlink capabilities is set on a per cell basis by the
                     OMC. This means the BTS can override the request from the
                     MSC.  This is, the BSS can make ultimate decision on
                     providing DTX downlink.

              -      DTX aims at increasing the system efficiency through
                     decrease of the interference level, by inhibiting the
                     transmission of the radio signal when not required from an
                     information point of view.  DTX feature is optional and
                     must therefore be managed.


4.1.4.4 CALL TRACE

       This functional specification describes the Call Trace feature and its
       implementation in the interWAVE WAVEXpress/BSC and WAView/OMC.

       As described in GSM 12.08: The trace facility enables customer
       administration and network management to trace the activities of various
       entities when specific events occur within the PLMN.  This facility
       should also enable the tracing of all the information that is available
       to the PLMN concerning the call path used by the associated entity.

       After integration of the Call Trace functionality into the BSS, the BSC
       will respond to MSC to BSS Invoke Trace messages by compiling trace
       records, and forwarding trace records to an OMC.  The BSS implementation
       of Call Trace will incorporate only a subset of the BSS Call Trace
       functionality defined in GSM 12.08.

       It provides the essential subscriber and equipment trace functionality as
       defined in GSM Specification 12.08.  It's capabilities and benefits are:

       -      Support for 08.08 MSC and BSS Invoke Trace Messages.

       -      Support for normal and priority Basic, Handover and Radio
              BSS Trace Types.

       -      GSM 12.08 Standard BSS Trace Record viewable from OMC.

       -      Enables an operator to trace the activities of various
              network entities when specific events occur within the PLMN
              including the call path used by the entity.

       -      Satisfies regulatory requirement in most countries.

4.1.4.5 DOUBLE BCCH (BA) ALLOCATION

       The purpose of this feature is to maintain two sets of neighbor lists
       within the BSS. One set is used by the mobile while it is camping on the
       cell in the IDLE mode. The other set is used by the mobile while a call
       is active on the Mobile. This feature allows more control on a cell
       traffic. This feature is useful in case of overlay/underlay cell, where
       the mobile camps on the macrocell in Idle mode and when the call is
       active, it handed over to underlay micro cell where it will have
       different list of neighbors.


       In order to take advantage of this feature, the operator is recommended
       to place all cells in the idle mode list, but only neighboring cells in
       the active list. Since all cells are in the idle list, the mobile will
       not try to reach the cells it was near when it is powered off. This could
       avoid the problem with mobiles accessing cells that are far away when a
       user powers-up the phone.

       It provides capability to maintain both an idle and an active mode
       neighbour list within the BSS. It's capabilities and benefits are:

              -      Allows more control on cell traffic.

              -      It is useful in cases of overlay/underlay cell plan that
                     the mobile camps on the macrocell in idle mode and
                     subsequently is handed over to the underlay microcell.


4.1.4.6 CALL QUEUING

       It provides Call Queuing function as defined in GSM Specification 08.08,
       GSM 04.22 and GSM 12.20.  It's capabilities and benefits are:

              -      Support for queuing during initial assignment, subsequent
                     assignment and handover, and queuing priority.

              -      Support to set queue length, enable/disable priority,
                     assignment request time limit  and handover request time
                     limit from the OMC.

              -      Provides full compliment of viewable operational
                     statistics.

              -      Provides operator the ability to reduce call failure rate.


4.1.4.7 IDLE CHANNEL INTERFERENCE OVER THRESHOLD NOTIFICATION

       The goal of this feature to send a notification to OMC in case
       interference level crosses a threshold set by the operator. BSS shall
       support 6 quality bands and a measurement period. The alarm threshold
       should be settable between 0 and 5. OMC threshold bands should be part of
       templates.

       This feature requires BSS to send a minor alarm every time the
       interference on an Idle TCH/F channel crosses the threshold set by the
       operator. The alarm should be sent as a FailureEventReport against TrxCh
       object with severity as MINOR. BSS should also send a clearing event if
       the interference level goes below threshold set by the operator. BSS
       should keep the history of alarm to reduce the number of alarms sent to
       OMCR. Idle Channel Interference over Threshold alarm is sent for a TrxCh,
       BSS

<PAGE>

       should not repeat the alarm in case interference level for the same TrxCh
       remains above threshold value during next measurement period.

       Operator shall be able to set the threshold value per BTS basis.  All the
       trxch in a bts will use the same threshold value for notification of Idle
       Channel Interference Measurement over Threshold. The default value of
       this threshold should be set to 4.  BSC should also send a major alarm
       against TRX object if half or more than half of these trx channels
       crosses threshold value for interference level.  Operator should also be
       able to disable TrxCh alarms and just see the TRX alarm.

       In existing design we support 6 bands for Idle Channel Interference level
       defined in HandCont object under Bts object.  Operator can set the range
       for all the 6 bands through OMC/NMI.  Default values are shown in the
       table given below.

<TABLE>
<CAPTION>

- ----------------------------------------------------
         Band       Default Range

- ----------------------------------------------------
             5        > -90 dBm
- ----------------------------------------------------
</TABLE>

       It provides OMC notification when operator defined Idle Channel
       Measurement thresholds are exceeded.  It's capabilities and benefits are:

       -      The BSS will send a minor alarm to then OMC every time the
              interference level on an idle TCH/F Channel crosses the operator
              defined threshold.

       -      The threshold is settable per BTS from the OMC.

       -      Interference measurements are based on average of measurements
              taken over two minutes intervals.

       -      Provides improved measurement and diagnostic capability.


4.1.4.8 VERY EARLY ASSIGNMENT

       It provides Very Early Assignment as defined in GSM Specification 04.08,
       05.08, 08.08 ad 08.58.  It's capabilities and benefits are:

       -      VEA provides the ability to allocate a TCH at initial assignment,
              when it is probable that the requested connection will need such a
              channel.

       -      The following options are selectable from the OMC: disable, enable
              all, enable emergency calls only, enable only if all SDCCHs are in
              use, enable for emergency call or only if all SDCCHs are in use.

       -      Very early assignment scheme allows the network operator to
              minimize the number of SDCCH channels, thereby maximizing the
              number of TCH channels available. This can result in an increase
              in the call carrying capacity of the cell.

<PAGE>

4.1.4.9 DIRECTED RETRY ON CONGESTION

       When a connection is established, the cell is chosen by the MS according
       to the C1 or C2 cell selection/reselection criterion based on the
       downlink measurements and MS maximum transmission power only.  BSS may
       not agree this is the best cell because the uplink reception quality is
       not taken into account.  Therefore, when a TCH is to be assigned, a
       handover to another cell might be necessary due to the lack of channel
       resources or congestion in the original cell.  This process of
       SDCCH-to-TCH handover at the time of call set-up is called Directed
       Retry.

       Directed Retry On Congestion will make use of the congestion information
       in the original as well as the target cell. When a connection is
       requested and directed retry feature is enabled by the operator, a check
       will be made to verify that the congestion in the given cell is below an
       operator defined threshold, before making a request for a traffic
       channel. If the given cell is already congested, preferred target list
       generated from measurement reports will be used for directed retry. Flow
       chart at the end of the document illustrates the steps for this feature.

       The main thrust is to give more preference to ongoing calls by reserving
       some capacity per cell for incoming handover requests for ongoing calls.
       New O&M parameters are provided to allow the operator to specify the
       traffic load threshold (ranges from 0 to 100%) and the current level of
       traffic congestion (ranges from 0 to 100%).

       The purpose of this feature is to add the ability to consider the
       congestion level of a cell before requesting a traffic channel in that
       cell as a result of a directed retry.  It's capabilities and benefits
       are:

       -      Can be enabled/disabled from OMC.

       -      Provides the operator with the ability to give preference to
              on-going calls by reserving capacity on a per cell basis for HO
              requests.


4.1.4.10       AUTOMATIC TRX HARDWARE DETECTION

       The purpose of this feature is to allow hot insertion and removal of a
       TRX Module in WAVEXpress Chassis.  It's capabilities and benefits are:

       -      Automatic detection and update of a module insertion or removal.

       -      Automatic triggering of diagnostic tests upon insertion.

       -      OMC notification of changes.

       -      OMC update of module identification information

       -      Minimizes downtime due to repairs or system upgrades.

       -      Improves reliability of module identification information.

<PAGE>

4.1.4.11       BSC DUAL BAND - GSM900 & DCS1800

       The purpose of this feature is to provide BSC support for the management
       of both GSM900 and DCS1800 Base stations.

       It supports only string configuration with maximum of four BTS connected
       in chain. The limitation of four comes from the E1 card's current
       hardware, which can only support four Lapd connections.  The philosophy
       followed for the string configuration is during the initialization of
       BTS, a passthrough will be connected by making cross connects in wave
       express and  programming the time slot assignment ram in micro.  All the
       port 0 channels are connected to port 1 channels except the Lapd channel,
       which is read from flash.  This Lapd channel has to be programmed in
       flash before commissioning the BTS.  BTS will try to establish Lapd
       connection with BSC using this timeslot.  As soon as abismgr on the BSC
       having the same e1chan is unlocked, Lapd connection will be established
       and BTS will try to come up.  Care is to be taken that no two BTS in the
       chain should be programmed to come up on the same E1 Lapd channel.  If
       this is done then more distant BTS on the chain will not come up.  After
       BTS comes up, TRX channels will be connected to abis on getting
       notification from  BSC.  Thus Abis channels connected to TRX will also be
       dropped from passthrough. In short all the channels used by a particular
       BTS will not be passed through, while the rest will be.  In case of warm
       start TRX channels will be disconnected from abis channels and these
       disconnect abis channels will be made passthrough.  Also whenever TRX
       channel are disconnected, a passthrough will be connected on the
       corresponding abis channels.

       It's capabilities and benefits are:

       -      General compliance with GSM 03.26 "Multi-band operation of GSM/DCS
              1800 by a single operator.

       -      Operator selectable option of single-band or mixed-band neigbour
              mode.

       -      Operation of mixed-band BTSs in a daisy chain configuration.

       -      Ability to prioritize GSM900 or DCS1800 on cell selection and
              handover.

       -      Provides enhanced capacity due to sharing of BSC and E1 resources.


4.1.4.12       N-2 SOFTWARE SUPPORT

       It provides the ability to upgrade Release N-1 or N-2 BSS to Release N
       BSS without shutting down the BSC.  It's capabilities and benefits are:

       -      The N-2 compatibility feature only implies general GSM 12.21 and
              08.58 interface and functionality between the BSC and then BTS.
              Release specific compatibility must be addressed on a feature by
              feature basis.

       -      Minimizes down time during upgrade of network.


4.1.4.13       ALARM MANAGEMENT ENHANCEMENT

       It provides new TRX and E1 alarms, which consider the service impact to
       the parent BSC or BTS.  It's capabilities and benefits are:

<PAGE>

       -      Applies to TRX and E1 Port Objects only.

       -      Introduces a new attribute and severity, which represent the
              service impact of a TRX or E1 Port alarm on the parent BSC or BTS.

       -      Severity is determined dynamically based on the local severity of
              an event multiplied by a weighting factor based on a variety of
              factors including quantity and use of modules.

       -      Severity classes include Ceased, Critical, Major, Minor, Warning
              Level and indeterminate.

       -      Provides ability to report child object alarms based on service
              impact to parent object when reporting alarm.

<PAGE>


                                   SCHEDULE 4


                  CUSTOMER ADVOCACY PLAN (LEVEL 2 SUPPORT PLAN)

1.0    PURPOSE

       The purpose of this procedure is to describe the method and timeframe for
       escalating problems based upon the severity level and potential impact to
       the customer network, as reported by Lanka Cellular Services (Private)
       Limited (thereafter called "LCS")

2.0    SCOPE

       The procedure covers the process, which connects the Regional Level 2
       support offices in HK (thereafter called "Regional TAC") to the
       headquarters' operation and escalation to the HQ operation in Redwood
       City (thereafter called "Corporate TAC").

3.0    RESPONSIBILITY

       It is the responsibility of the Regional TAC manager to manage the
       overall call escalation process and ensure that the procedures for
       escalation are adhered to by the company.  It is the responsibility of
       the Regional TAC managers to insure that the cases are properly
       classified upon initial diagnosis by the case manager and then
       notification is sent to the Corporate TAC.

4.0    LEVEL 2 SUPPORT

       4.1    During the Support Period, the Regional TAC will provide a 24
              hours, 7 days hotline service to LCS to handle the requests for
              2nd Level Support

       4.2    On receiving of a TR report (the trouble report) from LCS,
              Regional TAC will start analyzing the TR and the associate
              severity/case/problem; and if deemed appropriate, a corresponding
              Scopus case will be opened and a Scopus case number will be
              allocated. The LCS can then use the TR number in all
              communications regarding the fault report.  LCS needs to supply
              their LCS TR number to Regional TAC for reference. This TR that
              LCS raised per each request to Regional TAC will be sent by soft
              copy to HK via emailing to [email protected]. Regional TAC will
              then answer those TR from LCS.

       4.3    The investigation will be conducted by the Regional TAC on
              receiving an emergency telephone call or TR reported by the LCS.
              The severity of the case will also be determined. Further, if such
              an investigation reveals an error, defect or malfunction in the
              software, the Regional TAC will ensure the problematic system
              return to service by using of a temporary solution, acceptable to
              the LCS (that is, a "workaround").

       4.4    If Regional TAC could not provide a "workaround" to the problem
              within the specific hours defined in Section 4.12, then the
              problem will be escalated to

<PAGE>

              Corporate TAC Support for further analysis. Please see section
              4.12 for more information.

       4.5    Local user or customer will ONLY called the emergency support
              telephone no. (that LCS has provided to subscriber), but NOT
              Regional TAC emergency telephone. This customer emergency support
              telephone number will be automatically routed back to LCS. LCS
              engineer will determine emergency and that on emergency they will
              call Regional TAC with a designated Regional TAC telephone number:
              93793981  (24 hours, 7 days per week) This will be mainly related
              to S1 and S2 issues. For S3 issues, LCS will send email to
              Regional TAC at designated email address.

       4.6    Regional TAC will call back to designated caller. The caller will
              be a LCS engineer and he will be responsible for including the
              appropriate LCS personnel into the conference call with Regional
              TAC. In most case it is assumed LCS engineer will be involved in
              the conference call. Regional TAC could also call LCS number
              (?????????) in cases Regional TAC would like emergency contact to
              LCS (for example, may be the caller is busy on telephone)

       4.7    If the working period has been passed and that the issue has not
              been solved or no "workaround" is available; this issue will be
              escalated to the next level of support in RWC: i.e. the Level 3;
              following the escalation procedure in Section 4.12. In case there
              is an urgent requirement to contact L3, Regional TAC may contact
              L3 support earlier for even faster resolution.

       4.8    If during the working period, there is a need for Regional TAC to
              remote accessing the OMC/BSC/BTS/WXC/Combo, or performing some
              destructive maintenance action; then this request for access or
              action will be made to the customer; via the responsible
              caller/LCS engineer.

       4.9    LCS and the Regional TAC will keep each other informed of the
              progress in resolving any fault, via regular communications.

       4.10   Visit to the LCS/Customer's sites by Regional TAC engineer for the
              purpose of investigation or fault resolution will need to be
              agreed separately between LCS and interWAVE.

       4.11   LCS/Regional TAC should agree on the severity level of the call
              using the following guideline.

       S1     EMERGENCY            System or network is down and unusable as a
                                   result of a problem which causes failures, or
                                   results in severe intermittent operations
                                   with no customer acceptable work-arounds, or
                                   the customer states the problem has a
                                   critical impact on their operation.

       S2     SIGNIFICANT          System or network is up and will run,
                                   however, the problem exists with impact
                                   significant impact and which has difficult or
                                   no work-arounds causing substantial
                                   performance degradation, or prevents the
                                   customer from using a critical feature of the
                                   product or the system.

<PAGE>

       S3     LIMITED IMPACT       System or network is up and running but minor
                                   problems exist having limited impact.
                                   Customer can use the system or product with
                                   limitation or workarounds that are not
                                   critically impacting the overall operations.
                                   This could be a non-problematic information
                                   issue.

6.0    PATCH DELIVERY

       All patches will be created from interWAVE Redwood City. Regional TAC can
       then access the patches from an internal interWAVE database. This applies
       to both emergency and non-emergency cases. The patch will be further
       prepared and validated in interWAVE HK  for the specific site environment
       or issues.

       Regional TAC will then send the final resolution patch  to LCS, at the
       designated email address; after the patch has been made ready/validated
       in Regional TAC in Hong Kong.

       The patch will only be regarded as "ready to be used by LCS" when LCS has
       received a final green signal from Regional TAC, via phone call or email.

       LCS will be responsible for establishing the most suitable choice of
       transmission medium with the local customer for the transmission of
       patch.

       Depending on the outcome of discussion, the patch will then be ultimately
       delivered to appropriate location; via the designated caller/LCS
       engineer. Regional TAC will also assist LCS to achieve this.

7.0    ACCESS TO OMCR

<PAGE>

       The Regional TAC will need to have dial-up access to the customer's OMCR
       to permit remote fault analysis.

       LCS will take step to negotiate with local customer, via LCS project
       control for the modem telephone number and modem facilities set up. LCS
       would also need to supply Regional TAC the password and  user name on the
       designated interWAVE  OMCR  machine for the purpose of remote system
       diagnosis.

                     attempt to remedy the problem being complained of).
                     If the Contractor's service representative

Information (as defined herein) by either Party, the Parties agree as follows:

       1.            As Used Herein:

       any subsidiary, division, affiliate, or parent company of such entity.

              "Proprietary Information" is defined as that Information owned or
       possessed by either Party that the said Party desires to protect as
       confidential against unrestricted disclosure or improper competitive use,
       and that is designated as such in the manner provided by this Agreement.

       2.     All Information that is disclosed by one Party ("Disclosing
       Party") to the other ("Receiving Party") and that is to be protected
       hereunder by the Receiving Party as Proprietary Information if in writing

       safeguards against the unauthorized disclosure of Proprietary Information
       and that it

       Receiving Party hereunder containing Proprietary Information of the

              (f)    is disclosed when the applicable period of confidentiality

       Each party may disclose any Proprietary Information to the extent that
       such Party has been advised by counsel that such disclosure is necessary
       to comply with laws or regulations, or as necessary in connection with
       the filing of any patent, copyright, or similar application or
       registration; provided that each Party shall give the other Party
       reasonable advance notice of such proposed disclosure, shall use its best
       efforts to secure confidential treatment of any such Proprietary
       Information and shall advise the other Party in writing of the manner of
       the disclosure.

       paragraph 3, and the terms of paragraph 4, shall continue for the period
       specified in paragraph 3.

       7.     Neither this Agreement nor the disclosure or receipt of
       Information shall constitute or imply a commitment by either Party with
       respect to present or future business arrangements or other subject
       matter not expressly set forth herein.

       8.     The Receiving Party shall have, or shall enter into, agreements

       patent application, trademark, copyright, software or trade secret.

       10.    Any amendment to this Agreement must be in writing and signed by
       authorized officials of each Party.  No failure or delay in exercising
       any right under this Agreement shall operate as a waiver thereof.

       the Disclosing Party in tangible form that is in the possession of the
       Receiving Party shall be returned to the Disclosing Party or destroyed.
