  The following summary is qualified in its entirety by the more detailed
information, including "Risk Factors" and the Consolidated Financial Statements
and Notes thereto, appearing elsewhere in this Prospectus. This Prospectus
contains forward-looking statements that involve risks and uncertainties. The
Company's actual results may differ materially from the results discussed in
the forward-looking statements. Factors that might cause such a difference
include, but are not limited to, those discussed in "Risk Factors" and
elsewhere in this Prospectus. Unless otherwise indicated, the information in
this Prospectus (i) assumes no exercise of the Underwriters' over-allotment
option, (ii) reflects, except in the Consolidated Financial Statements and
Notes thereto, the conversion of all outstanding shares of Convertible
Preferred Stock into Common Stock upon completion of this offering and (iii)
assumes the reincorporation of the Company from California to Delaware before
the effective date of this offering, and the associated changes in the
Company's charter documents.     
 
                                  THE COMPANY
   
  E-Tek Dynamics, Inc. ("E-Tek" or the "Company") is a leader in the design,
packaging and manufacturing of high quality passive components and modules for
fiber optic networks. The Company offers a broad product line and believes it
has a leading share in markets for several key passive components required by
telecommunications equipment manufacturers. The Company is focused on
delivering high performance and reliable optical components for applications
which include wavelength division multiplexing ("WDM") and optical amplifiers.
The Company's products are designed for the established terrestrial and
submarine long-haul markets as well as emerging short-haul markets, such as
metropolitan area networks. The Company's customers include telecommunications
equipment manufacturers such as Alcatel, CIENA, Corning, Lucent, Nortel and
Pirelli. The Company has been profitable for the last five years and had $106.9
million in net revenues and $17.9 million in net income for the fiscal year
ended June 30, 1998.     
   
  The volume of traffic carried by telecommunication service providers has
rapidly increased over the last several years, creating capacity constraints on
heavily used short- and long-haul routes that were originally designed for
significantly less traffic. This increase has resulted in the widespread
deployment of new fiber optic networks and the adoption of new technologies to
increase the bandwidth capacity of existing fiber optic networks. The Company
believes that the growth of new and existing applications for optical
networking will drive the need for higher performance and increasingly
integrated components and modules, which are the key building blocks for
systems and subsystems in these networks. According to data provided by
ElectroniCast Corporation (a market research firm specializing in communication
networks and products) the worldwide optical network market, including passive
and active components as well as subsystems, but excluding fiber optic cable,
is expected to grow at approximately 28.7% per year from $2.3 billion in 1996
to $8.1 billion in 2001.     
 
  E-Tek's strategy is to leverage its market leadership to provide a broad
range of high quality components in large volumes for current and next
generation optical networking systems. Key elements of this strategy include:
(i) investing in product enhancements and developing new products to maintain
and expand E-Tek's leadership in passive optical components; (ii) leveraging
its design and packaging expertise to manufacture integrated components and
modules; (iii) continuing to deliver a high level of value-added service to
strengthen its existing customer relationships and develop new ones; (iv)
enhancing its manufacturing capabilities to provide rapid delivery of large
volumes of high quality, lower cost components; and (v) strengthening its
position in existing markets as well as penetrating new markets by expanding
its sales and marketing efforts to target new customers.
 
  The Company was incorporated in Florida in May 1983, reincorporated in
California in September 1987 and will reincorporate in Delaware prior to the
effective date of this offering. The Company's principal executive offices are
located at 1865 Lundy Avenue, San Jose, California 95131, and its telephone
number is (408) 546-5000.

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered by this Prospectus
involves a high degree of risk. Prospective purchasers of the Common Stock
offered hereby should carefully review the following risk factors as well as
the other information set forth in this Prospectus. This Prospectus contains
forward-looking statements that involve risks and uncertainties. The Company's
actual results could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set
forth in the following risk factors and elsewhere in this Prospectus.
 
DEPENDENCE ON A LIMITED NUMBER OF MAJOR CUSTOMERS
   
  A small number of customers have accounted for a significant portion of the
Company's net revenues to date, and the Company expects that this trend will
continue for the foreseeable future. Sales to the Company's largest customers,
affiliates of Alcatel Alsthom ("Alcatel"), affiliates of Pirelli SpA
("Pirelli"), and Corning, Inc. ("Corning") accounted for approximately 30.2%,
16.5% and 14.3%, respectively, of the Company's net revenues in fiscal 1998
and 43.5%, 5.2% and 15.0%, respectively, of the Company's net revenues in the
fourth quarter of fiscal 1998. Moreover, sales to the Company's five largest
customers and their affiliates represented approximately 73.4% and 77.5% of
the Company's net revenues in fiscal 1998 and in the fourth quarter of fiscal
1998, respectively. The Company expects to continue to be substantially
dependent on sales to its largest customers. In addition, the
telecommunications equipment industry is dominated by a small number of large
companies and is currently consolidating, thereby further reducing the number
of potential customers in the industry. The Company's dependence on large
orders from very few customers makes the relationship between the Company and
each customer critically important to the Company's business. There can be no
assurance that the Company will retain its largest customers or that it will
be able to attract additional customers. The Company has in the past
experienced delays and reductions in orders from its major customers. Further,
the Company's customers have in the past and will in the future seek price
concessions from the Company. The loss of one or more of the Company's largest
customers, any reduction or delay in sales to these customers, the inability
of the Company to successfully develop relationships with additional
customers, or any further price concessions could have a material adverse
effect on the Company's business, financial condition and results of
operations.     
   
  Almost all of the Company's customers are third party original equipment
manufacturers ("OEMs") that purchase the Company's components and modules for
use in systems manufactured and sold by them. In order for an OEM customer to
incorporate the Company's products into its systems, the Company must
demonstrate that its products provide significant commercial advantages over
competing products. There can be no assurance that the Company can
successfully demonstrate such advantages or that the Company's products will
continue to provide any advantages. Moreover, even if the Company is able to
demonstrate such advantages, there can be no assurance that OEMs will elect to
incorporate the Company's products into their current or future systems.
Further, the business strategies and manufacturing practices of the Company's
OEM customers are subject to change and any such change may result in
decisions by its customers to decrease their purchases of the Company's
products, seek other sources for products currently manufactured by the
Company or manufacture these products internally. Failure of OEMs to
incorporate the Company's products into their systems, the failure of such
OEMs' systems to achieve market acceptance or any other event causing a
decline in the Company's sales to OEMs would have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."     
 
FLUCTUATIONS IN QUARTERLY AND ANNUAL RESULTS; SEASONALITY
 
  The Company's net revenues and operating results have in the past varied and
may in the future vary significantly from quarter to quarter and from year to
year as a result of a number of factors.
 
                                       5
<PAGE>
 
   
These factors may include the size and timing of customer orders, the ability
to obtain sufficient supplies of sole or limited source materials for the
Company's products, the ability to manufacture products to meet customer
demands on a timely basis, pricing pressure from customers and competitors,
potential price rebates, customer requirements, the ability to meet customer
specifications, product qualification demands, and changes in the product mix
and shipments of components, among other factors. The Company's dependence on
a small number of customers increases the revenue impact of each customer's
actions relative to these factors. In addition, a significant portion of the
Company's expenses are relatively fixed in advance, based in large part on the
Company's forecasts of future sales. If sales are below expectations in any
given period, the adverse effect of a shortfall in sales on the Company's
operating results may be magnified by the Company's inability to adjust
spending to compensate for such shortfall. For example, in the second and
third quarters of fiscal 1998, net revenues decreased in part due to a decline
in sales to a major customer, as well as a reduction in average selling prices
("ASPs"). Due to this likelihood of significant quarterly fluctuation in
operating results, the Company believes quarter to quarter comparisons of its
results of operations may not necessarily be meaningful indicators of annual
performance.     
   
  The Company's orders fluctuate from quarter to quarter. To achieve its
revenue objectives, the Company is generally dependent upon obtaining orders
for shipment in that same quarter. Further, the Company's agreements with its
customers generally do not contain binding purchase commitments and generally
provide that its customers may change delivery schedules and cancel orders
within specified timeframes without significant penalty. The Company generally
recognizes revenue upon shipment of products to the customer. Refusal of
customers to accept shipped products, returns of shipped products or delays or
difficulties in collecting accounts receivable could result in significant
charges against income, which could have a material adverse effect on the
Company's business, financial condition and results of operations. The
inability to obtain sufficient orders in any quarter, or the cancellation or
deferral of such orders in a quarter, could have a material adverse effect on
the Company's business, financial condition and results of operations.     
 
  The Company has experienced and expects to continue to experience
seasonality in its business. The Company's sales have been affected by a
seasonal decrease in demand in the last quarter of each calendar year. The
Company expects this trend to continue, although other trends may emerge.
These trends, or other fluctuations in the timing of customer orders, may
cause quarterly or annual fluctuations and could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
DEPENDENCE ON LIMITED NUMBER OF PRODUCT LINES
   
  A small number of products have historically accounted for a majority of the
Company's net revenues, and the Company expects that this trend will continue
for the foreseeable future. In particular, sales of isolators accounted for
approximately 51.2% of the Company's net revenues in fiscal 1998. The
Company's other significant products include wavelength division multiplexing
("WDM") components and modules. The Company expects to continue to be
substantially dependent on sales of a limited number of product lines in the
near future. The Company anticipates, however, that growth in net revenues
from sales of its isolators will decline in the future due to continued
declines in their ASPs as well as the trend toward integration of isolators
into micro-optic integrated components ("MOICs"). If sales of its other
product lines do not increase, any decline in net revenues from sales of the
Company's isolators would have a material adverse effect on the Company's
business, financial condition and results of operations. There can be no
assurance that the Company will be successful in developing any other products
or taking other steps to mitigate the risks associated with reduced demand for
its existing products. Reduced demand for the Company's existing products
would have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Products."     
 
                                       6
<PAGE>
 
DEPENDENCE ON TELECOMMUNICATIONS INDUSTRY
   
  The Company's future success is dependent on the continued growth and
success of the telecommunications industry, which is evolving rapidly as
telecommunication markets around the world deregulate and open to global
competition. Generally, these factors have resulted in increased competition
and demand for telecommunications products and services, which have in turn
driven increased demand for the Company's products. There can be no assurance,
however, that globalization, deregulation and other trends causing an increase
in the need for bandwidth that are currently driving growth in the
telecommunications industry will continue in a manner that is favorable to the
Company. The telecommunications industry is also experiencing rapid
consolidation and re-alignment as industry participants position themselves to
capitalize on the rapidly changing competitive landscape developing around new
communications technologies such as fiber optic and wireless communications
networks, as well as the Internet. Further, the rate at which long distance
carriers and other fiber optic network users have built new fiber optic
networks or installed new systems in their existing fiber optic networks has
fluctuated in the past and such fluctuations may continue in the future. Such
fluctuations may result in reduced demand for new or upgraded fiber optic
systems that utilize the Company's products and, therefore, result in reduced
demand for the Company's products, which would have a material adverse effect
on the Company's business, financial condition and results of operations.
There can be no assurance that technological or other developments in the
telecommunications industry will favor growth in the markets served by the
Company's products. Moreover, as the telecommunications industry consolidates
and re-aligns to accommodate technological and other developments, there is a
risk that certain of the Company's customers and telecommunication service
providers may consolidate or align themselves together in a manner that
materially and adversely affects the Company's business, financial condition
and results of operations.     
 
RISKS OF LONG AND UNPREDICTABLE SALES CYCLES; LIMITED LONG-TERM CONTRACTS;
SHORT LEAD TIMES
   
  The period of time between the Company's initial contact with a customer and
the receipt of an actual purchase order may span a year or more. In addition,
customers perform, and require the Company to perform, extensive and lengthy
product evaluation and testing of new components and modules before purchasing
and using them in their equipment. The Company's customers do not typically
share information on the duration or magnitude of planned purchasing programs,
nor do they generally provide advance notice of contemplated changes in their
component purchasing priorities. The Company generally does not have long-term
contracts with its customers. Sales are typically made pursuant to individual
purchase orders, often with extremely short lead times, that may be canceled
or deferred by customers on short notice without significant penalty. These
uncertainties substantially complicate the Company's manufacturing planning.
Curtailment or termination of customer purchasing programs, decreases in
purchased volumes or reductions in the purchasing of certain components,
particularly if unanticipated by the Company, could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."     
 
DECLINE IN AVERAGE SELLING PRICES
   
  The fiber optic component industry is characterized by declining ASPs
resulting from factors such as increased competition and greater unit volumes
as telecommunication service providers continue to deploy fiber optic
networks. The Company has in the past and may in the future experience
substantial period to period fluctuations in operating results due to
declining ASPs. The Company anticipates that ASPs will decrease in the future
in response to product introductions by competitors or the Company or other
factors, including price pressures from significant customers. In particular,
the market for low-end isolators and couplers has experienced and may continue
to experience significant ASP declines that have contributed and may in the
future continue to contribute to a decline in the Company's gross margins.
Therefore, the Company must continue to develop and introduce on a     
 
                                       7
<PAGE>
 
timely basis new products that incorporate features that can be sold at higher
ASPs, as well as reduce its manufacturing costs. Failure to achieve any or all
of the foregoing could cause the Company's net revenues and gross margins to
decline, which would have a material adverse effect on the Company's business,
financial condition and results of operations.
 
COMPETITION; CUSTOMERS AS COMPETITORS
   
  The market for fiber optic components is intensely competitive and
characterized by rapidly changing technology. The Company currently
experiences competition from various companies including, among others: (i)
FDK Corporation, Kyocera Corp. and Shinkosha K.K. in isolators, (ii) Lucent
Technologies Inc., Corning, Inc. and JDS FITEL, Inc. in WDM components and
modules and (iii) ADC Telecommunications, Inc. and Gould Electronics, Inc. in
couplers. The Company also faces competition from numerous smaller companies.
Many of the Company's current and potential competitors have significantly
greater financial, technical, marketing, purchasing and other resources than
the Company, and as a result, may be able to respond more quickly to new or
emerging technologies or standards and to changes in customer requirements, to
devote greater resources to the development, promotion and sale of products,
or to deliver competitive products at a lower prices. Many of these
competitors manufacture their products in countries offering significantly
lower labor costs than in the United States.     
   
  Existing and potential customers are also current and potential competitors
of the Company. These companies may develop or acquire additional competitive
products or technologies in the future and thereby reduce or cease their
purchases from the Company. For example, one of the Company's customers
recently purchased a fiber optic component manufacturer and began
manufacturing a product internally that it formerly purchased from the
Company. The Company may also face competition in the future from these and
other parties that develop fiber optic components based upon the technologies
similar to or different from the technologies employed by the Company. The
Company expects competition in general to intensify substantially, and further
expects competition to be broadly based on varying combinations of
manufacturing capacity, ability to deliver on-time, technical features,
quality and reliability, customization to customer specifications, strength of
distribution channels, pricing and comprehensiveness of product offerings.
There can be no assurance that the Company will be able to compete
successfully with its existing or new competitors or that competitive
pressures faced by the Company will not result in lower prices for the
Company's products, loss of market share, or reduced gross margins, any of
which could materially and adversely affect the Company's business, financial
condition and results of operations.     
   
MANUFACTURING AND FACILITIES EXPANSION RISKS     
 
  The Company currently manufactures all of its products at its facilities in
San Jose, California. The Company is in the process of increasing its
manufacturing capacity at these facilities and adding overseas manufacturing
capabilities. The Company has increased its capacity by expanding the size of
its San Jose facilities from approximately 90,000 square feet to approximately
160,000 square feet. The Company has been moving portions of its operations,
including manufacturing, to these buildings as space becomes available. There
can be no assurance that the Company will not experience business
interruptions as it relocates certain of its personnel and equipment. Any such
interruptions or other transition difficulties could have a material adverse
effect on the Company's business, financial condition and results of
operations.
   
  In addition, in an effort to increase the Company's manufacturing capacity
and reduce its manufacturing costs, as well as to expand the Company's sales
and marketing presence in Asia, the Company has recently entered into a joint
venture with a Taiwanese company to build and operate a fiber optic component
manufacturing facility in Taiwan (the "FibX Joint Venture"). The Company
believes that this new facility will begin commercial production in 1999. The
construction of this new     
 
                                       8
<PAGE>
 
   
facility and the expansion of existing facilities entail significant risks,
including shortages of materials and skilled labor, unanticipated cost
increases, unavailability or late delivery of process equipment, unforeseen
environmental or engineering problems, work stoppages, political instability,
weather interferences, any of which could have a material adverse effect on
the start up or operation of the new facility. In addition, unexpected changes
or concessions required by regulatory agencies with respect to necessary
licenses, land use permits, site approvals and building permits could involve
significant additional costs and delay the scheduled opening of the facility
and could reduce the Company's anticipated net revenues. Following the
completion of the FibX facility, the Company must install equipment and
perform necessary testing and qualification procedures prior to commencing
commercial production at the facility. As a result of the foregoing and other
factors, there can be no assurance that the project will be completed within
its current budget or within the period currently scheduled by the Company,
either of which could have a material adverse effect on the Company's
business, financial condition and operating results. Furthermore, if the
Company is unable to achieve adequate manufacturing yields at the FibX
facility in a timely manner, or at all, or if the Company's net revenues do
not increase commensurate with the anticipated increase in manufacturing
capacity associated with the new facility and the expansion of its existing
facilities, the Company's business, financial condition and operating results
could also be materially adversely affected.     
   
  The Company's manufacturing expansion and related capital expenditures are
being made in anticipation of a level of customer orders that may not be
sustained over multiple quarters, if at all. If anticipated levels of customer
orders are not received, the Company will not be able reduce its expenses
quickly enough to prevent a decline in the Company's gross margins and
operating income. Such decline would have a material adverse effect on the
Company's business, financial condition and results of operations.     
   
  The Company will be required to hire, train and manage additional production
personnel in order to increase its production capacity as scheduled. The
Company has in the past experienced and in the future may continue to
experience substantial manufacturing capacity constraints. In the past, the
Company has been unable to accept certain orders from, and deliver products in
a timely manner to, its customers due to such constraints. In the event the
Company's plans to expand its manufacturing capacity are not implemented on a
timely basis, the Company could face production capacity constraints, which
could have a material adverse effect on the Company's business, financial
condition and operating results. In addition, the Company may be required to
make additional capital investments in new or existing manufacturing
facilities. To the extent such capital investments are required, the Company's
gross margins and, as a result, its business, financial condition and
operating results, could be materially and adversely affected.     
   
  The Company will also have to effectively coordinate and manage two
manufacturing facilities to successfully meet its overall production goals.
The Company has no experience in coordinating and managing production
facilities that are located at different sites or in the transfer of
manufacturing operations from one facility to another. As a result of these
and other factors, the failure of the Company to successfully coordinate and
manage multiple sites or to transfer the Company's manufacturing operations
could adversely affect the Company's overall production and could have a
material adverse effect on its business, financial condition and results of
operations. See "Business--Manufacturing."     
 
MANAGEMENT OF EXPANSION
   
  The Company is rapidly expanding certain aspects of its operations,
particularly its manufacturing operations, and the Company anticipates that
this expansion will continue in the near future. The Company intends to
satisfy its working capital and capital expenditure requirements with cash
flow from operations and available borrowings under its credit facilities. As
part of this expansion, the Company has rapidly increased its employee base,
from 439 employees on June 30, 1997 to     
 
                                       9
<PAGE>
 
657 employees on June 30, 1998. The Company intends to continue to add and
train new employees as its expands. The pace of the Company's expansion, in
combination with the complexity of the technology involved in the manufacture
of the Company's products, demands an unusually high level of managerial
effectiveness in anticipating, planning, coordinating and meeting the
operational and personnel needs of the Company and the needs of the Company's
customers for quality, reliability and timely delivery. Many of the Company's
key employees have not had previous experience in managing companies
undergoing such rapid expansion. Any inability to manage the expansion of the
Company's business could have a material adverse effect on its business,
financial condition and results of operations. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
DEPENDENCE ON SUPPLIERS
   
  The Company is dependent on a limited number of suppliers of materials for
its products as well as equipment used to manufacture its products. Some of
the Company's suppliers are sole sources, and finding an alternative source
might involve significant expense and delays, if such a source could be found
at all. The Company has in the past been unable to ship products due to
shortages of sole-sourced materials. Substantially all of the Company's
revenues are derived from products incorporating one or more sole-sourced
materials. The reliance on a sole or limited number of suppliers has in the
past and could in the future result in lost orders, reduced control over
pricing, quality and delivery schedules, as well as the need to redesign a
product due to a failure to obtain a single source component. Any interruption
in supply of single source materials could have a material adverse effect on
the Company's business, financial condition and results of operations.     
 
  The Company has to date conducted its business with suppliers through the
issuance of conventional purchase orders based on the Company's forecasted
requirements. The Company has in the past experienced delays in the receipt of
key materials and has been unable to accept customer orders for Company
products that require such materials. The Company generally does not maintain
long-term agreements with its suppliers, and therefore the supply of a
particular material could be terminated at any time without penalty to the
supplier. Any future difficulty in obtaining sufficient and timely delivery of
materials could result in delays or reductions in product shipments. In the
event that any significant supplier or subcontractor were to become unable or
unwilling to continue to manufacture or ship materials in required volumes,
the Company would have to identify and qualify acceptable replacements. A
delay or reduction in material shipments or any need to identify and qualify
replacement suppliers could have a material adverse affect on the Company's
business, financial condition and results of operations.
   
DEPENDENCE ON THIRD PARTY SALES REPRESENTATIVES AND DISTRIBUTORS     
   
  The Company sells substantially all of its products through a network of
seven domestic and 22 international sales representatives and distributors.
Substantially all of the Company's sales representatives and distributors have
exclusive sales territories pursuant to contracts with the Company that are
generally terminable at the Company's option, subject to certain notice
periods. The Company's sales representatives and distributors participate in
the Company's sales and marketing efforts by developing and maintaining
relationships with key customer contacts, cross-marketing the Company's
products to its existing customer base, communicating technical specifications
and other requirements of its customers to the Company's product development
engineers, and providing customer support after the sale. Although the Company
intends to increase the number of sales representatives and distributors that
market and sell its products as its customer base expands, and to selectively
expand its direct marketing and sales force to take advantage of new customer
opportunities, the Company expects that it will continue to rely on its
independent sales representatives and distributors to market, sell and support
many of its products. In addition, substantially all of the Company's sales
representatives and distributors have exclusive rights to sell the Company's
products     
 
                                      10
<PAGE>
 
   
in certain territories, which limits the Company's ability to add additional
sales representatives and distributors. As a result, the Company's success
depends in part on the continued viability and financial stability of the
Company's sales representatives and distributors. The sales representative and
distributor industries have been historically characterized by rapid change
and instability resulting from widespread financial difficulties, industry
consolidation and the emergence of competing distribution channels. In
addition, certain of the Company's sales representatives and distributors
carry products of one or more of the Company's competitors, and such sales
representatives and distributors may carry more such products in the future.
Accordingly, there is a risk that the Company's sales representatives and
distributors may emphasize the products of one or more of the Company's
competitors at the expense of their sales and marketing efforts on behalf of
the Company's products. There can be no assurance that the Company's sales
representatives or distributors will recommend, or continue to recommend, the
Company's products, or that the Company's sales representatives or
distributors will devote sufficient resources to market the Company's products
or provide sufficient customer support for such products. The loss of, or
reduction in sales made by, one or more of the Company's key sales
representatives or distributors, or the inability to attract and retain new
sales representatives or distributors that satisfy the Company's standards,
could have a material adverse effect on the Company's business, financial
condition or results of operations.     
 
TECHNOLOGICAL CHANGE AND NEW PRODUCTS
 
  The Company expects that new technologies will emerge as competition in the
telecommunications equipment industry increases and the need for higher and
more cost efficient bandwidth expands. The Company's ability to anticipate
changes in technology, industry standards, customer requirements and product
offerings and to develop and introduce new and enhanced products will be
significant factors in determining the Company's long-term success. The market
for fiber optic components is characterized by significant capital investment,
diverse and competing technologies, rapid product introduction and
obsolescence of existing products. The introduction of new products
incorporating new technologies or the emergence of new industry standards
could render the Company's existing products uncompetitive, obsolete or
unmarketable. The development of new, technologically advanced products is a
complex and uncertain process requiring high levels of innovation and highly
skilled assembly and manufacturing processes, as well as the accurate
anticipation of technological and market trends. Many of the Company's
competitors have substantially greater financial, technical, manufacturing and
marketing resources with which to develop new technologies and to promote
market acceptance of their products. There can be no assurance that the
Company will be able to identify, develop, manufacture, market or support new
or enhanced products successfully or on a timely basis, that new Company
products will gain market acceptance or that the Company will be able to
respond effectively to product announcements by competitors, technological
changes or emerging industry standards. Any of these outcomes would have a
material and adverse effect on the Company's business, financial condition and
results of operations.
 
PRODUCT COMPLEXITY
 
  Products as complex as those offered by the Company may contain defects when
first introduced or as new versions are released and new products often take
longer to develop than originally anticipated. In the past, the Company has
experienced such defects and delays in development and volume production. In
particular, the Company has experienced defects and delays in production of
integrated products. Delivery of products with production defects or
reliability or quality problems could significantly delay or hinder market
acceptance of such products, which could damage the Company's reputation and
adversely affect the Company's ability to retain its existing customers and to
attract new customers. Moreover, such defects could cause problems,
interruptions, delays or cessation of sales to the Company's customers.
Alleviating such problems may require significant expenditures of capital and
resources by the Company. There can be no assurance that, despite testing by
the Company, its suppliers or its customers, defects will not be found in new
products after commencement of
 
                                      11
<PAGE>
 
commercial production, resulting in additional development costs, loss of, or
delays in, market acceptance, diversion of technical and other resources from
the Company's other development efforts, claims by the Company's customers or
others against the Company, or the loss of credibility with the Company's
current and prospective customers. Any such event would have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS; CURRENCY RISKS
   
  The Company generates a significant portion of its net revenues from sales
to companies located outside the United States, principally in Europe.
Approximately 53.4%, 42.2% and 36.5% of the Company's net revenues in fiscal
1998, 1997 and 1996, respectively, were derived from sales to customers
located outside the United States, and the Company anticipates that
international sales will continue to account for a significant portion of its
net revenues. As a result, a significant portion of the Company's sales and
operations may continue to be subject to certain risks, including government
controls, export licensing requirements and restrictions, tariffs and other
trade barriers, slower accounts receivable cycles, currency exchange risks and
exchange controls and potential adverse tax consequences. Demand for the
Company's products could also be adversely affected by seasonality of
international sales and economic conditions in Europe and the Company's other
overseas markets. These factors could have a material adverse effect on future
sales of the Company's products to international customers and, consequently,
on the Company's business, financial condition and results of operations.     
   
  The Company anticipates shifting the manufacturing of certain of its mature
products offshore to the FibX Joint Venture in 1999. Foreign manufacturing is
subject to a number of other risks, including currency fluctuations,
transportation delays and interruptions, difficulties in staffing, potentially
adverse tax consequences and unexpected changes in regulatory requirements,
tariffs and other trade barriers, and political and economic instability. The
location of the FibX facility in Taiwan will also subject the Company to the
risk of political instability, including but not limited to the potential for
conflict between Taiwan and the People's Republic of China. Any of these risks
could have a material adverse effect on the Company's business, financial
condition and results of operations.     
 
  Currently, all of the Company's international sales are U.S. dollar-
denominated. As a result, an increase in the value of the U.S. dollar relative
to foreign currencies could make the Company's products less competitive in
international markets. There can be no assurance that the Company will not be
required to or otherwise accept payment in foreign currencies in the future.
The Company's operating results could become subject to significant
fluctuations based upon changes in the exchange rates of certain currencies in
relation to the U.S. dollar. Although management will continue to monitor the
Company's exposure to currency fluctuations, and, when appropriate, may use
financial hedging techniques in the future to minimize the effect of these
fluctuations, there can be no assurance that exchange rate fluctuations will
not have a material adverse effect on the Company's business, financial
condition and results of operations in the future.
 
RECENT MANAGEMENT ADDITIONS AND DEPENDENCE ON KEY EMPLOYEES
 
  The Company's senior management personnel have worked together for only a
short time. The Company's Chief Executive Officer joined the Company in
October 1997 and three of the Company's other four executive officers have
joined the Company since that time. The success of the Company is dependent,
in large part, on the long-term effectiveness of its executive officers and
their continued service to the Company. The Company does not have key man life
insurance coverage on any of its executive officers. The loss of the services
of any of the Company's executive officers could have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Management."
 
                                      12
<PAGE>
 
   
  The Company's success will also depend in large part upon its ability to
attract and retain highly-skilled technical, managerial, sales and marketing
personnel, particularly those skilled and experienced with fiber optics.
Competition for such personnel, particularly in the United States, is intense.
The Company has entered into employment agreements with several of its key
employees. See "Management--Employment Agreements and Change of Control
Arrangements." In addition, the Company has in the past recruited engineering
and technical personnel from China, Taiwan and other countries and assisted
such personnel in obtaining the necessary visas to work in the United States.
There can be no assurance that the Company will be able to recruit key
personnel from such countries in the future or that the Company will be able
to obtain visas for the skilled workers it seeks to hire. Furthermore, there
can be no assurance that the Company will be able to retain its existing key
personnel or any new key personnel. Failure to attract and retain key
personnel would have a material adverse effect on the Company's business,
financial condition and results of operations.     
 
RISKS ASSOCIATED WITH PATENTS AND INTELLECTUAL PROPERTY RIGHTS
   
  The Company's success will depend, in part, on its ability to protect its
intellectual property. The Company relies primarily on patent, copyright,
trademark and trade secret laws, as well as nondisclosure agreements and other
methods to protect its proprietary technologies and processes. There can be no
assurance that such measures will provide meaningful protection for the
Company's proprietary technologies and processes. As of June 30, 1998, the
Company had 42 U.S. patents issued and 24 U.S. and 18 foreign patent
applications pending. These patents expire between 2007 and 2016. There can be
no assurance that any patent will issue as a result of these applications or
future applications or, if issued, that any patent claims allowed will be
sufficiently broad to protect the Company's technology. In addition, there can
be no assurance that any existing or future patents will not be challenged,
invalidated or circumvented, or that any right granted thereunder would
provide meaningful protection to the Company. The failure of any patents to
provide protection to the Company's technology would make it easier for the
Company's competitors to offer similar products. The Company also generally
enters into confidentiality agreements with its employees and strategic
partners, and generally controls access to and distribution of its
documentation and other proprietary information. Despite these precautions, it
may be possible for a third party to copy or otherwise obtain and use the
Company's products or technology without authorization, develop similar
technology independently or design around the Company's patents. In addition,
effective patent, copyright, trademark and trade secret protection may be
unavailable or limited outside of the United States, Europe and Japan.There
can be no assurance that the Company will be able to obtain any meaningful
intellectual property protection in such countries and territories. Further,
the Company occasionally incorporates the intellectual property of its
customers into its designs, and the Company has certain obligations with
respect to the non-use and non-disclosure of such intellectual property. There
can be no assurance that the steps taken by the Company to prevent
misappropriation or infringement of the intellectual property of the Company
or its customers will be successful. Moreover, litigation may be necessary in
the future to enforce the Company's intellectual property rights, to protect
the Company's trade secrets or to determine the validity and scope of
proprietary rights of others, including its customers. Such litigation could
result in substantial costs and diversion of the Company's resources and could
have a material adverse effect on the Company's business, financial condition
and results of operations.     
 
  The telecommunications equipment industry is characterized by vigorous
protection and pursuit of intellectual property rights. From time to time, the
Company has received, and may continue to receive in the future, notices of
claims of infringement of other parties' proprietary rights. There can be no
assurance that the Company will prevail in actions alleging infringement by
the Company of third-party patents or the invalidity of the patents held by
the Company will not be asserted or prosecuted against the Company, or that
any assertions of infringement or prosecutions seeking to establish the
invalidity of Company-held patents will not materially and adversely affect
the Company's business, financial
 
                                      13
<PAGE>
 
condition and results of operations. For example, in a patent or trade secret
action, an injunction could issue against the Company requiring that the
Company withdraw certain products from the market or necessitating that
certain products offered for sale or under development be redesigned. The
Company has also entered into certain indemnification obligations in favor of
its customers and strategic partners that could be triggered upon an
allegation or finding of the Company's infringement of other parties'
proprietary rights. Irrespective of the validity or successful assertion of
such claims, the Company would likely incur significant costs and diversion of
its resources with respect to the defense of such claims, which could also
have a material adverse effect on the Company's business, financial condition
and results of operations. To address any potential claims or actions asserted
against it, the Company may seek to obtain a license under a third party's
intellectual property rights. There can be no assurance that under such
circumstances a license would be available on commercially reasonable terms,
if at all.
   
  Substantial inventories of intellectual property are held by a few industry
participants, such as Lucent Technologies Inc., Northern Telecom Limited and
certain major universities and research laboratories. This concentration of
intellectual property in the hands of a few major entities also poses certain
risks to the Company in seeking to hire qualified personnel. The Company has
on a few occasions recruited such personnel from such entities. There can be
no assurance that these entities or others will not claim the misappropriation
or infringement of their intellectual property, particularly when and if
employees of these entities leave to work for the Company. There can be no
assurance that the Company will be able to avoid litigation in the future,
particularly if new employees join the Company after having worked for a
competing company. Such litigation could be very expensive to defend,
regardless of the merits of the claims, and could have a material adverse
effect on the Company's business, financial condition and results of
operations.     
 
RISKS ASSOCIATED WITH POTENTIAL ACQUISITIONS AND STRATEGIC INVESTMENTS
   
  The Company expects to review acquisition and strategic investment prospects
that would complement its existing product offerings, augment its market
coverage, secure supplies of critical materials or enhance its technological
capabilities. Although the Company has no current agreements with respect to
any material acquisitions or investments, the Company may make acquisitions of
or investments in businesses, products or technologies in the future. From
time to time, the Company has considered increasing its ownership interest in
a joint venture with its German distributor, AMS OptoTech GmbH ("AMS"), from
its current level of 40%. AMS owns the other 60%. Future acquisitions or
investments by the Company, including an increase in ownership interests in
joint ventures, could result in potentially dilutive issuances of equity
securities, large one-time write-offs, the incurrence of debt and contingent
liabilities and amortization expenses related to goodwill and other intangible
assets.     
 
  Furthermore, acquisitions entail numerous risks, including difficulties in
the assimilation of operations, personnel, technologies, products and the
information systems of the acquired companies, diversion of management's
attention from other business concerns, the diversion of resources from the
Company's existing businesses, products or technologies, risks of entering
geographic and business markets in which the Company has no or limited prior
experience and the potential loss of key employees of acquired organizations.
The Company has not made any material acquisitions in the past. No assurance
can be given as to the ability of the Company to successfully integrate any
businesses, products, technologies or personnel that might be acquired in the
future. The failure of the Company to do so could have a material adverse
effect on the Company's business, financial condition and results of
operations.
 
                                      14

ENVIRONMENTAL AND DISASTER RISKS
 
  The Company owns its facilities in San Jose and recently purchased five
acres of vacant land near these facilities. Although the Company believes that
it has complied with all applicable environmental regulations in connection
with its land purchases, there can be no assurance that the Company will not
be required to undertake environmental remediation in order to comply with
current or future environmental laws. The cost of any remedial actions or the
paying of penalties or damages for environmental matters, regardless of fault,
could have a material adverse effect on the Company's business, financial
condition and results of operations.
   
  The Company is subject to extensive federal, state and local environmental
laws, rules, regulations and ordinances that govern activities or operations
that may have adverse environmental effects, such as discharges to air and
water, as well as handling and disposal practices for solid and hazardous
wastes, and impose liability for the costs of cleaning up, and certain damages
resulting from, past spills, disposals or other releases of hazardous
substances (together, "Environmental Laws"). The Company handles small amounts
of hazardous materials as part of its manufacturing activities and its
facilities are located in close proximity to semiconductor manufacturers and
other companies which routinely handle hazardous substances. Although the
Company endeavors to handle all such materials in compliance with applicable
law, penalties or damages for violations of Environmental Laws relating to the
Company's handling of these materials, or for liability under any other
Environmental Laws, could have a material adverse effect on the Company's
business, financial condition and results from operations.     
 
  The Company's facilities, which are located in a seismically active area,
are susceptible to damage from earthquakes as well as from fire, floods, power
loss, telecommunications failures and similar events. The Company does not
currently have a disaster recovery plan in effect to respond to these events.
The occurrence of any of these events could significantly disrupt the
Company's operations and would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
YEAR 2000 COMPLIANCE
   
  Many currently installed computer systems, software products and other
control devices are coded to accept only two digit entries in the date code
fields, which will need to accept four digit entries to distinguish 21st
century dates from 20th century dates. As a result, many companies' computer
systems, software products and control devices may need to be upgraded or
replaced in order to comply with such "Year 2000" requirements. The Company
relies on its systems, applications and control devices in operating and
monitoring all major aspects of its business. The Company recently installed
new Enterprise Resource Planning software at a cost of approximately
$1.0 million which the Company believes is Year 2000 compliant. The Company
believes its other systems, software and devices are also Year 2000 compliant.
Nonetheless, the Company is in the process of reviewing the effect of
Year 2000 issues on its other systems, software and devices and expects to
complete the review by the end of calendar 1998. The Company also relies,
directly and indirectly, on external systems of its customers, suppliers,
creditors, financial organizations, utilities providers and governmental
entities, both domestic and international. Consequently, the Company could be
affected through disruptions in the operations of the enterprises with which
the Company interacts. Furthermore, the purchasing frequency and volume of
customers or potential customers may be affected by Year 2000 issues as
companies expend significant resources to make their current systems Year 2000
compliant. The Company does not currently have in place any contingency plans
for its operations if Year 2000 issues are not resolved in time or go
undetected. The incomplete or untimely resolution of any of these issues could
have a material adverse effect on the Company's business, financial condition
and results of operations.     
 
                                      15
<PAGE>
 
   
RESCISSION OFFER     
   
  From February 4, 1998 to August 14, 1998, the Company issued options to
purchase 3,303,375 shares of its Common Stock to 493 employees of the Company
without complying with certain filing requirements of the California blue sky
laws. As a result, such option grants and the subsequent issuance of Common
Stock upon the exercise of certain of these options were not qualified under
the California state securities laws or otherwise exempt from qualification
under these laws. The Company has recently filed for a permit from the
California Commissioner of Corporations to conduct a rescission offer for the
options and the shares of Common Stock that have been issued pursuant to
certain of these options (the "Rescission Offer"). Pursuant to the Rescission
Offer, the Company will offer to rescind each option grant by repurchasing the
option for 20% of the exercise price of the option (which exercise prices
range from $3.25 to $12.00), plus interest at the statutory rate of seven
percent from the date of grant. In the case of options that have been
exercised, the Company will offer to repurchase the resulting Common Stock for
the full amount of the exercise price, plus seven percent interest from the
date of exercise. If all offerees accept the Rescission Offer, the Company
would be required to make aggregate payments of approximately $6.2 million
plus the aggregate amount of interest as described above. The Company does not
expect to use any portion of the proceeds from the offering to make payments
under the Rescission Offer. Once the Company receives a permit to conduct the
Rescission Offer, the Rescission Offer will commence and remain open until the
earlier of 30 days or such time as all offerees have responded to the
Rescission Offer. After such time, these offerees will no longer have a right
to rescind their options and such options shall be qualified under the
California securities law. There can be no assurance, however, that the
Company will receive a permit to conduct the Rescission Offer, that the
Company will not be required to pay significant amounts to the offerees as a
result of their acceptance of the Rescission Offer, or that the Rescission
Offer will not have a material adverse effect on the Company's business,
financial condition and results of operations.     
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
   
  Sales of a substantial number of shares of Common Stock after the offering
could adversely affect the market price of the Common Stock and could impair
the Company's ability to raise capital through the sale of equity securities.
Upon completion of the offering, the Company will have outstanding 61,442,498
shares of Common Stock, assuming no exercise of options after June 30, 1998.
All of the 6,000,000 shares offered hereby (6,900,000 shares if the
Underwriters' over-allotment option is exercised in full) will be freely
tradable without restriction or further registration under the Securities Act
of 1933, as amended (the "Securities Act"), unless purchased by "affiliates"
of the Company as that term is defined in Rule 144 under the Securities Act
("Rule 144") described below. The remaining 55,442,498 shares of Common Stock
outstanding upon the closing of this offering will be "restricted securities"
as that term is defined in Rule 144 (assuming no exercise of the Underwriters'
over-allotment option).     
   
  Restricted securities may be sold in the public market only if registered or
if they qualify for an exemption from registration under Rules 144, 144(k) or
701 promulgated under the Securities Act. As a result of the contractual
restrictions described below and the provisions of Rules 144, 144(k) and 701,
additional shares will be available for sale in the public market as follows:
55,442,498 shares will become eligible for sale upon expiration of the lock-up
agreements between stockholders of the Company and the representatives of the
Underwriters following the expiration of 180 days from the date of this
Prospectus, 53,606,111 of which shares shall initially be subject to the
volume and manner of sale restrictions under Rule 144. In addition to the
foregoing, as of September 21, 1998, there were options outstanding under the
Company's 1997 Equity Incentive Plan and 1997 Executive Equity Incentive Plan
(the "Plans"), to purchase an aggregate of 4,319,788 shares of Common Stock,
of which options to purchase 623,146 shares were vested. As of September 21,
1998, no shares have been issued under the 1998 Director Option Plan, the 1998
Employee Stock Purchase Plan or the     
 
                                      16
<PAGE>
 
   
1998 Stock Plan. The shares underlying such options will be eligible for sale
upon expiration of the lock-up provisions contained in the plans following the
expiration of 180 days from the date of this Prospectus, subject in certain
cases to such shares underlying outstanding options becoming eligible for sale
more than 180 days after the date of this Prospectus as such options vest. The
Company has agreed not to release shares from these lock-up provisions without
the prior written consent of Goldman, Sachs & Co. In addition, the Company
intends to register, following this offering, the sale of shares of Common
Stock subject to outstanding options or reserved for issuance under the
Company's new and existing plans, thereby permitting the resale of such shares
by nonaffiliates in the public market without restriction under the Securities
Act. Further, certain stockholders holding approximately 52,444,445 shares of
Common Stock are generally entitled to demand registration of their shares of
Common Stock following the expiration of 180 days from the date of this
Prospectus as well as to "piggy-back" on certain registration statements filed
by the Company in the future. By exercising their demand registration rights,
such stockholders could cause a large number of securities to be registered
and sold in the public market, which could have an adverse effect on the
market price of the Common Stock. See "Management--Stock Plans,"
"Underwriting," "Shares Eligible for Future Sale" and "Description of Capital
Stock--Registration Rights."     
 
NO PRIOR TRADING MARKET FOR THE COMMON STOCK; POSSIBLE VOLATILITY OF STOCK
PRICE
   
  Prior to this offering, there has been no public market for the Common Stock
of the Company. The initial public offering price will be determined by
negotiations among the Company and the representatives of the Underwriters and
may not be indicative of the price that will prevail on the open market. See
"Underwriting" for a discussion of the factors to be considered in determining
the initial public offering price. There can be no assurance that an active
public market will develop or be sustained after this offering or that the
market price of the Common Stock will not decline below the initial public
offering price. Future announcements concerning the Company or its
competitors, quarterly or annual variations in operating results,
announcements of technological innovations, the introduction of new products
or changes in product pricing policies by the Company or its competitors,
proprietary rights or product liability litigation or changes in earnings
estimates by analysts could cause the market price of the Common Stock to
fluctuate substantially. In addition, the stock market has from time to time
experienced significant price and volume fluctuations that have particularly
affected the market prices for the securities of technology companies. In the
past, following periods of volatility in the market price of a particular
company's securities, securities class action litigation has often been
brought against such company. There can be no assurance that such litigation
will not occur in the future with respect to the Company. Such litigation
could result in substantial costs and a diversion of management's attention
and resources, which could have a material adverse effect upon the Company's
business, operating results and financial condition.     
 
CONTROL BY EXISTING STOCKHOLDERS
   
  The Company's founders, officers, directors and their affiliates will, in
the aggregate, beneficially own approximately 82.8% of the Company's
outstanding shares after this offering. As a result, these stockholders, if
acting together, would be able effectively to control substantially all
matters requiring approval by the stockholders of the Company, including the
election of directors and approval of significant corporate transactions. This
ability may have the effect of delaying or preventing a change in control of
the Company, or causing a change in control of the Company which may not be
favored by the Company's other stockholders. See "Principal and Selling
Stockholders."     
 
                                      17
<PAGE>
 
DISCRETIONARY USE OF PROCEEDS
   
  Of the net proceeds to the Company from the offering, estimated at
approximately $36.2 million, a substantial portion will be used for general
corporate purposes and have not been designated for any particular purpose.
Accordingly, the Company will have broad discretion as to the application of
such proceeds. See "Use of Proceeds."     
 
EFFECT OF CERTAIN CHARTER, BYLAW AND OTHER PROVISIONS
   
  Certain provisions of the Company's Certificate of Incorporation (the
"Certificate of Incorporation") and bylaws could have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party
from attempting to acquire, control of the Company. In addition, the Company
licenses technology from certain third parties pursuant to licenses that
contain provisions restricting or eliminating the Company's rights to use the
technology following an acquisition of the Company. Any of the foregoing
provisions could limit the price that certain investors might be willing to
pay in the future for shares of the Company's Common Stock. The Certificate of
Incorporation and bylaws allow the Company to issue preferred stock with
rights senior to those of the Common Stock without any further vote or action
by the stockholders, provide for a classified board of directors, eliminate
the right of the stockholders to call a special meeting of stockholders,
eliminate the right of stockholders to act by written consent, and impose
various procedural and other requirements which could make it difficult for
stockholders to effect certain corporate actions. See "Description of Capital
Stock."     
 
ABSENCE OF DIVIDENDS; IMMEDIATE AND SUBSTANTIAL DILUTION
   
  The Company currently intends to retain any future earnings to fund its
growth and, therefore, does not anticipate paying any dividends in the
foreseeable future. Purchasers of the Common Stock offered hereby will suffer
immediate and substantial dilution of $8.58 per share in the net tangible book
value of the Common Stock from the initial public offering price (at an
assumed initial public offering price of $10.00 per share). To the extent
outstanding options to purchase the Company's Common Stock are exercised,
there will be further dilution. See "Dividend Policy," "Dilution" and "Shares
Eligible for Future Sale."

<PAGE>
 
                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 4,000,000 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$36.2 million at an assumed initial public offering price of $10.00 per share,
after deducting the underwriting discount and estimated offering expenses.
       
  The Company intends to utilize the net proceeds from this offering for
working capital and general corporate purposes, including $32.0 million of
capital expenditures to support manufacturing, product development, and
selling, general and administrative activities. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources." A portion of the proceeds may also be used to acquire or
invest in complementary businesses or products or to obtain the right to use
complementary technologies. From time to time, in the ordinary course of
business, the Company evaluates potential acquisitions of or investments in
such businesses, products or technologies. However, the Company has no present
understandings, commitments or agreements with respect to any material
acquisition of or strategic investment in other businesses, products or
technologies. Pending use of the net proceeds for any purposes, the Company
intends to invest such funds in short-term, interest-bearing, investment grade
obligations. The Company will not receive any proceeds from the sale of the
shares being sold by the Selling Stockholders. See "Principal and Selling
Stockholders."     
 
                                DIVIDEND POLICY
   
  The Company has never paid or declared any cash dividends on its Common
Stock or on its Convertible Preferred Stock. It is the present policy of the
Company to retain earnings to finance the growth and development of the
business and, therefore, the Company does not anticipate declaring or paying
cash dividends on its Common Stock in the foreseeable future. In addition, the
Company's line of credit restricts the Company from paying cash dividends on
its capital stock without the lender's prior consent.

                                CAPITALIZATION
   
  The following table sets forth the capitalization of the Company as of June
30, 1998 (i) on an actual basis, (ii) on a pro forma basis to reflect the
conversion of all outstanding shares of Convertible Preferred Stock into
30,000,000 shares of Common Stock upon the closing of this offering and the
reincorporation of the Company in Delaware and (iii) as adjusted to reflect
the sale of 4,000,000 shares of Common Stock offered by the Company hereby (at
an assumed initial public offering price of $10.00 per share) and the
application of the estimated net proceeds therefrom. This table should be read
in conjunction with the Company's Consolidated Financial Statements and Notes
thereto appearing elsewhere in this Prospectus.

                                   DILUTION
   
  The pro forma net tangible book value of the Company as of June 30, 1998,
was $50.6 million, or approximately $0.88 per share of Common Stock. Pro forma
net tangible book value per share represents the amount of the Company's pro
forma stockholders' equity, divided by 57,299,252 pro forma shares of Common
Stock outstanding as of June 30, 1998. The preceding pro forma information
gives effect to the conversion of the Company's Convertible Preferred Stock
into 30,000,000 shares of Common Stock. Assuming the sale by the Company of
4,000,000 shares of Common Stock offered hereby at an assumed initial public
offering price of $10.00 per share and receipt of the estimated net proceeds
therefrom, the pro forma adjusted net tangible book value of the Company as of
June 30, 1998 would have been approximately $86.8 million or $1.42 per share.
This represents an immediate increase in such net tangible book value of $0.54
per share to existing stockholders and an immediate dilution of $8.58 per
share to new investors. The following table illustrates this per share
dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
information included elsewhere in this Prospectus. The information in this
Prospectus contains certain forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from the
results discussed in the forward-looking statements as a result of certain
factors, including those set forth under "Risk Factors" and elsewhere in this
Prospectus.
 
OVERVIEW
 
  The Company designs, packages, manufactures and sells high quality passive
components for fiber optic networks. E-Tek was incorporated in Florida in May
1983, reincorporated in California in 1987 and will be reincorporated in
Delaware prior to the effective date of this offering. The Company has been
profitable for the last five years, and has focused on providing optical
components for the telecommunications industry since 1989. In July 1997, the
Company underwent a recapitalization in which it sold a controlling stake in
the Company through the issuance of Convertible Preferred Stock which has
significant rights and preferences over the Common Stock, including rights to
elect a majority of the Company's directors, cumulative dividends and a
liquidation preference. In connection with the recapitalization, the Company
also repurchased Common Stock from the Company's founders. In late calendar
1997, E-Tek hired a number of new executive officers, including its Chief
Executive Officer and Chief Financial Officer, to lead the Company in
anticipation of future growth and expansion.
 
  The Company generates revenues primarily from the sale of components and
modules. Revenue from product sales is generally recognized at the time the
product is shipped, with provisions established for estimated product returns
and allowances. A relatively small number of telecommunications equipment
manufacturers have accounted for a significant portion of the Company's
revenue to date. This has historically resulted in an uneven order flow driven
by fluctuating demand for the Company's products. In addition, the Company's
sales have been affected by a seasonal decrease in demand in the last quarter
of each calendar year.
 
  The fiber optic components industry is characterized by declining ASPs
resulting from such factors as increased competition and increasing unit
volumes as telecommunication service providers continue to deploy and expand
fiber optic networks. Cost and component size reductions driven by advances in
component technology and manufacturing efficiencies, as well as the increasing
integration of components, are expected to accelerate the rate of growth in
existing optical components markets and enable new markets such as
metropolitan area networks. As a result, telecommunications equipment
manufacturers are increasingly demanding high volume manufacture of low cost,
high performance, integrated components.
 
  The Company is engaged in continuing efforts to expand its manufacturing
capabilities to address historical capacity constraints and anticipated unit
volume growth. Beginning in December 1997, the Company increased the size of
its San Jose facility from approximately 90,000 square feet to approximately
160,000 square feet and purchased approximately $7 million of capital
equipment. The Company increased its number of manufacturing employees from
396 in December 1997 to 525 in June 1998. In addition, the Company has
recently entered into a joint venture with a Taiwanese company (the "FibX
Joint Venture") to build and operate a fiber optic component manufacturing
facility in Taiwan. The Company anticipates it will begin manufacturing
certain of its mature products at the FibX facility in 1999.
 
  In fiscal 1998, the Company derived approximately 53.4% of its revenues from
sales to customers outside the United States, principally in Europe. All sales
are denominated in U.S. dollars and the Company had no foreign exchange
exposures at June 30, 1998.
 
                                      23
<PAGE>
 
   
  Fluctuations in the Company's operating results have occurred in the past
and are likely to occur in the future due to a variety of factors, any of
which may have a material adverse effect on the Company's operating results.
In particular, the Company's quarterly and annual results of operations have
in the past varied and may in the future vary significantly due to general
business conditions in the fiber optic equipment industry, customer
concentration, seasonal fluctuations in demand, changes in demand for the
products of the Company's customers, changes in the mix of products sold by
the Company, the timing and amount of orders from the Company's customers,
cancellations or delays of customer product orders, new product introductions
by the Company or its competitors, cancellations, changes or delays of
deliveries of products to the Company by its suppliers, increases in the costs
of products from the Company's suppliers, fluctuations in product life cycles,
decline in ASPs, competition, changes in the Company's manufacturing capacity,
loss of or reduction in sales by sales representatives and distributors,
intellectual property disputes and general economic conditions. Since a large
portion of the Company's operating expenses, including salaries and
depreciation, is fixed and difficult to reduce, the material adverse effect of
any revenue shortfall will be magnified by the fixed nature of these operating
expenses. All of the above factors are difficult for the Company to forecast,
and these and other factors could have a material adverse effect on the
Company's business, financial condition and results of operations. In
addition, the Company's visibility regarding future customer demand is
limited. As a result of all of the foregoing, there can be no assurance that
the Company will be able to sustain profitability on a quarterly or an annual
basis. Moreover, the Company believes that period to period comparisons are
not necessarily meaningful and should not be relied upon as indicative of
future operating results. The Company's operating results in a future quarter
or quarters are likely to fall below the expectations of public market
analysts or investors. In such event, the price of the Company's Common Stock
will likely be materially adversely affected.     
 
DEFERRED COMPENSATION EXPENSE
   
  Through August 1998, the Company recorded aggregate deferred stock
compensation of approximately $2.5 million in connection with the issuance of
stock options to employees. This deferred compensation, representing the
difference between the deemed fair value of the Company's Common Stock and the
exercise price of the stock options at the date of grant, is amortized on a
straight-line basis over the vesting period, which is generally 48 months. The
Company recognized approximately $290,000 in deferred stock compensation
expense during fiscal 1998. The Company expects amortization of approximately
$550,000 during each of the next four fiscal years.     
 
  During fiscal 1998, under the Company's stock option plans, the Company
issued 7,211,000 shares of Common Stock to employees and officers of the
Company in exchange for promissory notes in an aggregate principal amount of
$18,215,000. Because the notes do not bear interest, the $18,215,000 face
value was discounted using a 6% interest rate to $13,615,000 with the
difference recorded as deferred compensation cost. As this cost is expensed,
it will be offset by a corresponding non-cash interest income benefit,
resulting in no net effect pre-tax or net income. During fiscal 1998, the
Company recognized $600,000 in employee compensation expense, which was offset
by $600,000 in imputed interest income. In fiscal 1999 the Company expects to
recognize approximately $1.2 million in offsetting compensation expense and
interest income.
 
  These amortization amounts will be allocated to cost of goods sold, research
and development, and selling, general and administrative expenses based on the
applicable job function of each optionee.

  NET REVENUES. Net revenues increased 46.2% to $106.9 million for fiscal 1998
from $73.1 million for fiscal 1997, and increased 80.9% in fiscal 1997 from
$40.4 million for fiscal 1996. The net revenue increases were primarily due to
increased unit shipments of the Company's isolators, WDM components and
modules, micro-optic integrated components, and couplers, and in fiscal 1998,
also due to substantial growth in sales of products for submarine
applications. Higher unit volumes contributed to 73.5% of the increase in net
revenues whereas unit price increases contributed 26.5%. While ASPs for
specific components declined, these declines were offset by a change in
product mix towards more integrated, higher priced units. A relatively small
number of customers have accounted for a significant portion of the Company's
total revenue to date, and the Company expects that this trend will continue
for the foreseeable future. Sales to the Company's three largest customers,
Alcatel, Pirelli and Corning, accounted for approximately 30.2%, 16.5% and
14.3% respectively, of the Company's net revenues in fiscal 1998.     
   
  GROSS PROFIT. Gross profit increased 36.2% to $57.9 million for fiscal 1998
from $42.5 million for fiscal 1997, and increased 65.5% in fiscal 1997 from
$25.7 million for fiscal 1996. Cost of goods sold consists of raw material
costs, direct labor costs, warranty costs, royalties and overhead related to
the Company's manufacturing operations. Gross profit margins declined during
this period primarily due to declining ASPs and the Company's substantial
expansion of its manufacturing capacity to address historical capacity
constraints and anticipated unit volume growth. The Company's gross margins in
the future may be affected by a number of factors, including levels of revenue
achieved, market pricing, manufacturing volumes, efficiencies and yields,
fluctuations in the availability and price of raw materials, product mix and
labor costs.     
 
  RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses consist
of compensation costs for research and development staff, depreciation of
equipment, prototype materials and overhead allocations for facilities and
services. Research and development expenses were $7.7 million, $4.0 million
and $2.4 million for fiscal 1998, 1997 and 1996, respectively, representing
7.2%, 5.4% and 6.1% of net revenues, respectively. The increase for
expenditures over this period was primarily due to the Company's investment in
the development of new products and
 
                                      25
<PAGE>
 
product enhancements and an increase in personnel. The Company expects to
continue to make substantial investments in research and development and
anticipates that research and development expenses will continue to increase
in fiscal 1999 in absolute dollars. To date, the Company has not capitalized
any research and development costs.
   
  SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses consist of compensation costs for selling, general and
administrative staff, sales commissions, travel expenses, marketing staff and
programs, professional services, accounting, human resources, executive
management and consulting. Selling, general and administrative expenses were
$21.1 million, $15.3 million and $8.8 million for fiscal 1998, 1997 and 1996,
respectively, representing 19.7%, 20.9% and 21.7% of net revenues,
respectively. The absolute increase in expenditures over this period reflected
the hiring of additional selling, marketing and administrative personnel and
increased commissions paid on higher revenues, as well as the amortization of
deferred compensation expense described above. The Company anticipates that
its selling, general and administrative expenses will increase in absolute
dollars during fiscal 1999 as additional personnel are hired and commissions
increase, but may vary as a percentage of net revenues depending on the
Company's future net revenues.     
 
  INTEREST INCOME AND INTEREST EXPENSE. The Company's interest income was
approximately $2.0 million, $1.0 million and $408,000 for fiscal 1998, 1997
and 1996, respectively. The Company earns interest income on its short-term
investments. In addition, the Company recognized imputed interest income in
fiscal 1998 of $600,000 related to notes receivable from stockholders.
Interest expense, incurred on borrowings secured by the Company's real
property and on capital leases, was $988,000, $571,000 and $66,000 for fiscal
1998, 1997 and 1996, respectively.
 
  PROVISION FOR INCOME TAXES. The Company's combined federal and state income
tax rate was approximately 40%, 36% and 37% in fiscal 1998, 1997 and 1996,
respectively. The effective income tax rate for fiscal 1998 is higher than the
rates for fiscal 1997 and fiscal 1996 because of a permanent tax difference
related to the Company's investment in the FibX Joint Venture. This permanent
difference is a result of a license fee from the FibX Joint Venture for
certain technology, which is recognized as revenue for income tax purposes but
not for financial reporting purposes.

  NET REVENUES. Quarterly net revenues increased in each of the three quarters
ended September 30, 1997 due to higher unit shipments of both existing
products and new products and the overall growth of the fiber optic market.
Net revenues declined in the quarters ended December 31, 1997 and March 31,
1998 primarily due to a decline in sales to a major customer, as well as a
reduction in ASPs. In addition, the results for the quarter ended December 31,
1997 were adversely affected by reduced seasonal demand for optical
components. Net revenues increased in the quarter ended June 30, 1998
primarily due to a resumption of product purchases by such customer, an
increase in product sales for submarine applications and increasing unit
shipments generally.
 
  GROSS PROFIT. Gross profit declined over the six quarters from 58.1% in the
quarter ended March 30, 1997 to 51.5% in the quarter ended June 30, 1998
primarily due to declining ASPs and, beginning in December 1997, due to the
increase in the Company's manufacturing capacity to address historical
capacity constraints and anticipated unit volume growth. This capacity
expansion has substantially increased the Company's fixed costs, and the
Company's gross profits will therefore be adversely affected if anticipated
levels of customer sales do not occur or are delayed.
 
  OPERATING EXPENSES. Research and development expenses increased as a
percentage of revenues through the quarter ended June 30, 1998 as the Company
developed additional products, including associated personnel costs, facility
costs, and related project material purchases. Selling, general and
administration expenses also increased in fiscal 1998 as a result of the
amortization of deferred compensation costs related to employee stock options
and to non-interest bearing notes receivable from stockholders. Selling,
general and administrative expenses generally increased as a percentage of net
revenues during the same period although such expenses declined in absolute
dollars in the quarters ended December 31, 1997 and March 31, 1998 due to
lower sales commissions resulting from lower revenues.
 
YEAR 2000 COMPLIANCE
 
  Many currently installed computer systems and products are coded to accept
only two digit entries in the date code fields, which will need to accept four
digit entries to distinguish 21st century dates from 20th century dates. As a
result, many companies' computer systems may need to be upgraded or replaced
in order to comply with such "Year 2000" requirements. The Company relies on
its
 
                                      28
<PAGE>
 
   
systems, applications and control devices in operating and monitoring all
major aspects of its business. The Company recently installed new Enterprise
Resource Planning software at a cost of approximately $1.0 million which the
Company believes is Year 2000 compliant. The Company believes its other
systems, software and devices are also Year 2000 compliant. Nonetheless, the
Company is in the process of reviewing the effect of Year 2000 issues on its
other systems, software and devices and expects to complete the review by the
end of calendar 1998. The Company also relies, directly and indirectly, on
external systems of its customers, suppliers, creditors, financial
organizations, utilities providers and on governmental entities, both domestic
and international. Consequently, the Company could be affected through
disruptions in the operation of the enterprises with which the Company
interacts. Furthermore, the purchasing frequency and volume of customers or
potential customers may be affected by Year 2000 issues as companies expend
significant resources to make their current systems Year 2000 compliant. The
Company does not currently have any contingency plans for its operations if
Year 2000 issues are not resolved in time or go undetected. The incomplete or
untimely resolution of any of these issues could have a material adverse
effect on the Company's business, financial condition and results of
operations.     
 
RECAPITALIZATION
   
  In July 1997, the Company completed a recapitalization, pursuant to which it
sold a controlling stake in the Company through the issuance of Convertible
Preferred Stock for $120 million which has significant rights and preferences
over the Common Stock, including rights to elect a majority of the Company's
directors, cumulative dividends and a liquidation preference (the
"Recapitalization"). In connection with the Recapitalization, the Company also
repurchased $120 million in Common Stock from the Company's founders. The
Company recorded Convertible Preferred Stock accretion of $9.0 million during
fiscal 1998 related to the 8% per annum dividends payable on Convertible
Preferred Stock. Upon consummation of this offering, all shares of Convertible
Preferred Stock will convert to Common Stock and there will be no additional
accretion. The amount recorded for the Convertible Preferred Stock, including
accretion to date, will be transferred to Common Stock. See "Certain
Transactions--Recapitalization" and Note 1 of Notes to the Consolidated
Financial Statements.     
 
LIQUIDITY AND CAPITAL RESOURCES
   
  Since inception, the Company has financed its operations and met its capital
expenditure requirements primarily through cash flow from operations and
borrowings. As of June 30, 1998, the Company had $33.6 million of working
capital, including $21.9 million in cash and cash equivalents, as compared to
$27.7 million of working capital as of June 30, 1997, including $8.3 million
in cash and cash equivalents and $10.8 million in short-term investments.     
   
  The Company's operating activities generated net cash of $27.7 million for
fiscal 1998. This resulted primarily from net income of approximately $17.9
million, depreciation of $6.1 million and an increase in accounts payable and
accrued liabilities of $9.4 million, offset by an increase in deferred tax
assets and inventories of $6.8 million. The increase in accounts payable was
primarily due to an increase in inventory purchases as a result of an increase
in sales volume. The increase in accrued liabilities was due to an increase in
accrued compensation expense and accrued warranty expense. The increase in
deferred tax assets resulted mainly from the incurrence of expenses deductible
for book purposes that were not currently deductible for tax purposes.     
   
  For fiscal 1997, the Company generated $13.5 million net cash from operating
activities. This resulted primarily from $15.1 million net income, $3.1
million of depreciation and an increase in accrued liabilities of $5.9
million, offset by an increase in accounts receivable of $10.0 million. The
increase in accrued liabilities was due primarily to the increase in accrued
compensation and accrued warranty. The increase in accounts receivable was due
to the increase in sales.     
 
                                      29
<PAGE>
 
   
  For fiscal 1996, net cash provided by operating activities of $10.2 million
was due mainly to net income of $9.3 million and depreciation of $1.4 million.
       
  Net cash used in investing activities was $12.4 million for fiscal 1998 as
compared to $21.4 million for fiscal 1997 and $4.8 million for fiscal 1996,
and consisted primarily of capital expenditures. Capital expenditures for
fiscal 1998 were $19.1 million as compared to $18.2 million for fiscal 1997
and $1.9 million for fiscal 1996. The substantial increases in capital
expenditures in fiscal 1997 and 1998 were related to the November 1996
acquisition of the Company's previously leased San Jose manufacturing
facility, as well as additions to machinery and equipment, computers and
leasehold improvements in connection with such purchase. In fiscal 1999, the
Company expects to invest approximately $25 million in production equipment
and leasehold improvements in order to expand its San Jose manufacturing
capabilities and approximately $7 million in research and development and
general and administrative activities.     
   
  Net cash used in financing activities was $1.6 million for fiscal 1998 as
compared to $8.1 million of net cash provided by financing activities for
fiscal 1997 and $1.4 million of net cash used in financing activities for
fiscal 1996. The fiscal 1998 amount reflects the net effect of the
Recapitalization as well as the addition of $3.0 million of long term debt.
The fiscal 1997 amount reflects the incurrence of $7.7 million in long-term
debt in connection with the purchase of real estate and improvements for the
Company's San Jose facilities.     
   
  The Company has a $15.0 million revolving credit agreement with Bank of
America National Trust and Savings Association which expires on December 31,
1998, which is secured by the Company's accounts receivable, inventories and
equipment and contains customary restrictive covenants, including covenants
for minimum tangible net worth, liabilities to tangible net worth and cash
flow. The borrowings thereunder bear interest at a rate of LIBOR plus 1.5%. At
June 30, 1998, the Company had no borrowings outstanding under the revolving
credit agreement. The Company anticipates that the revolving credit agreement
will be renewed prior to its expiration.     
 
  The Company may in the future pursue acquisitions of, or strategic
investments in, businesses, products and technologies, or enter into
additional joint venture arrangements, that could complement or expand the
Company's business. From time to time, the Company has considered increasing
its ownership interest in a joint venture with its German distributor, AMS
OptoTech GmbH. Any material acquisition, strategic investment or joint venture
could result in a decrease in the Company's working capital depending on the
amount, timing and nature of the consideration to be paid.
   
  Pursuant to the FibX Joint Venture, the Company and the other investor each
contributed $7.0 million in cash for a 50% interest. Under the FibX Joint
Venture agreement and a related license agreement, the Company anticipates
receiving $7.0 million from the FibX Joint Venture for certain technologies of
the Company that were licensed to the FibX Joint Venture. See Note 3 of Notes
to Consolidated Financial Statements. The FibX Joint Venture agreement does
not require the Company to provide any additional financing to the FibX Joint
Venture.     
   
  The Company believes that the net proceeds from the offering, cash flow from
operations, existing cash and cash equivalent balances, short-term investment
balances, available borrowings under the revolving credit agreement and
capital leases will satisfy the Company's working capital and capital
expenditure requirements for at least the next 12 months, although the Company
may seek to raise additional capital during that period. There can be no
assurance the Company will not require additional funds prior to the
expiration of such 12 month period. Beyond the next 12 months, the Company
intends to satisfy its working capital and capital expenditure requirements
with cash flow from operations and available borrowings under credit
facilities. However, if such sources are insufficient, or even if they are
sufficient, the Company may seek additional debt or equity financing. The
Company requires substantial working capital to fund its business,
particularly to finance accounts     
 
                                      30
<PAGE>
 
receivable and inventory, and for investments in property, plant and
equipment, and may consume working capital more rapidly than currently
anticipated resulting in the need for additional capital. The Company's need
to raise additional equity or debt financing in the future will depend on many
factors, including the rate of sales growth, the market acceptance of the
Company's existing and new products, the amount and timing of research and
development expenditures, the timing and size of any acquisitions of
complementary businesses or the increase of its ownership interest in existing
joint ventures, products or technologies and the expansion of sales and
marketing efforts. There can be no assurance that such financing will be
available on acceptable terms, if at all, or that such financing will not be
dilutive to the Company's stockholders.
 
RECENT FINANCIAL PRONOUNCEMENTS
   
  In June 1997, the Financial Accounting Standards Board issued two new
Statements of Financial Accounting Standards ("SFAS"). SFAS 130, "Reporting
Comprehensive Income," establishes standards for reporting and display of
comprehensive income within a financial statement. This statement requires the
Company to report additional information on comprehensive income to supplement
the reporting of income. SFAS 130 is effective for fiscal years beginning
after December 15, 1997. Comparative financial statements provided for earlier
periods are required to be reclassified so that comprehensive income is
displayed in a comparative format for all periods presented. SFAS 131,
"Disclosures about Segments of an Enterprise and Related Information,"
establishes standards for reporting information about operating segments in
annual and interim financial statements. This statement also establishes
standards for related disclosures about products and services, geographic
areas and major customers. SFAS 131 is effective for financial statements for
fiscal years beginning after December 15, 1997. The Company will adopt SFAS
130 for fiscal 1999 and does not expect its provisions to have a material
effect on the Company's presentation of its consolidated financial statements.
The Company will adopt SFAS 131 for fiscal 1999 and is currently studying its
provisions.     
 
  In June 1998, the Financial Accounting Standards Board issued SFAS 133
"Accounting for Derivative Instruments and Hedging Activities." SFAS 133
establishes accounting and reporting standards for derivative instruments and
for hedging activities and is effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. The Company does not expect the adoption
of SFAS 133 to have a material impact on the Company's results of operations.

OVERVIEW
   
  E-Tek is a leader in the design, packaging and manufacturing of high quality
passive components for fiber optic networks. The Company offers a broad
product line and believes it has a leading share in markets for several key
passive components required by telecommunications equipment manufacturers. The
Company is focused on delivering high performance and reliable optical
components for applications which include wavelength division multiplexing
("WDM") and optical amplifiers. The Company's products are designed for the
established terrestrial and submarine long-haul markets as well as emerging
short-haul markets, such as metropolitan area networks. The Company's
customers include telecommunications equipment manufacturers such as
affiliates of Alcatel Alsthom ("Alcatel"), CIENA Corporation, Corning, Inc.
("Corning"), Lucent Technologies Inc. ("Lucent"), Northern Telecom Limited
("Nortel") and affiliates of Pirelli SpA ("Pirelli"). The Company has been
profitable for the last five years and had $106.9 million in net revenues and
$17.9 million in net income for the fiscal year ended June 30, 1998.     
 
INDUSTRY BACKGROUND
 
  The volume of traffic carried by telecommunication service providers on
their networks has rapidly increased over the last several years as a result
of the rapidly growing amount of data traffic and, to a lesser extent, voice
traffic. Data traffic has increased due to a proliferation of bandwidth
intensive applications such as Internet access, distributed computing, e-mail,
remote access and electronic commerce. Although telecommunication service
providers have increased the capacity of their networks by deploying fiber
optic cable for long-haul routes and, more recently, for short-haul routes
such as metropolitan area networks, the increase in demand for bandwidth has
created capacity constraints on these routes, which were originally designed
for significantly less traffic. Telecommunication service providers can
address their capacity constraints by either installing new fiber or expanding
the transmission capacity of existing fiber utilizing technologies such as
time division multiplexing ("TDM") and, more recently, WDM. TDM increases the
transmission speed of optical signals whereas WDM increases the number of
optical signals transmitted simultaneously on a single fiber. Regardless of
the method used for addressing capacity constraints, the demand for optical
networking equipment, including components, modules, subsystems and systems is
expected to increase.
   
  Optical components and modules are the building blocks of optical systems
and subsystems. There are two basic segments of optical components: passive
optical components, such as isolators, filters and couplers, which route and
guide light; and active components which generate light (source lasers),
amplify light (pump lasers) or detect light (photodetectors). The performance
of optical components is determined by the quality and processing of raw
materials and the quality of "packaging," which includes coating, fiber
alignment and encapsulation into a functional component. To minimize the
number of components, and thereby reduce costs and improve system reliability,
telecommunications equipment manufacturers are increasingly requiring the
integration of multiple components into a single module. For example, a
subsystem such as an Erbium Doped Fiber Amplifier (an "EDFA") is comprised of
multiple passive and active components. According to IGI Consulting (a market
research company specializing in telecommunications) the market for EDFAs
alone is expected to grow from $95 million in 1996 to $1.2 billion in 2002.
    
  The Company believes that the growth of new and existing applications for
optical networking will continue to drive the need for components and modules.
Improvements in component technology that increase component integration,
enhance performance, lower cost and increase reliability and quality are
expected to enable the increased deployment of optical networking equipment in
high growth markets such as submarine networks and metropolitan area networks.
In addition, these improvements may enable advancements in optical cross
connect and optical switching technology which are
 
                                      32
<PAGE>
 
   
expected to be the catalysts for a shift to all optical networks. According to
data provided by ElectroniCast Corporation (a market research firm
specializing in communication networks and products) the worldwide optical
network market, including passive and active components as well as subsystems,
but excluding fiber optic cable, is expected to grow at 28.7% per year from
$2.3 billion in 1996 to $8.1 billion in 2001.     
 
  The large number of different components and the rapid rate of technological
change make it difficult for telecommunications equipment manufacturers to
produce a full suite of components in-house without creating a large and
dedicated engineering and manufacturing workforce. When purchasing components
from third-party suppliers, telecommunications equipment manufacturers are
faced with a fragmented optical component market that includes a large number
of small vendors. Small vendors often possess a limited product line, lack the
ability to integrate components and are unable to scale production to deliver
high volumes of quality products in a timely manner. Because of these factors,
telecommunications equipment manufacturers often experience difficulty in
obtaining sufficient quantities of reliable and low-cost optical components to
meet their growing demand for optical networking systems.
 
THE E-TEK SOLUTION
 
  E-Tek is a leader in the design, packaging and manufacturing of high quality
passive components for fiber optic networks. The Company offers a broad
product line and believes it has a leading share in markets for several key
passive components required by telecommunications equipment manufacturers. The
Company is focused on delivering high performance and reliable optical
components for applications which include WDM and optical amplifiers. The
Company's products are designed for established terrestrial and submarine
long-haul markets as well as emerging short-haul markets, such as metropolitan
area networks. The Company believes it offers the following key advantages to
its customers:
 
  . BROAD PRODUCT LINE FOR OPTICAL SYSTEMS. The Company offers a broad line
    of high quality passive optical components such as isolators, WDM
    components and modules, couplers and micro-optic integrated components
    for telecommunications systems. The Company leverages product expertise
    from its multiple product lines to more effectively design and develop
    value-added integrated components and modules.
     
  . COMPONENT DESIGN, PACKAGING AND INTEGRATION EXPERTISE. E-Tek's ten years
    of experience in designing and packaging optical components enable it to
    integrate multiple optical functions into one micro-optic integrated
    component (a "MOIC"). For example, the Company recently introduced a
    product that combines tap coupler and isolator functions into a single
    module for use in EDFAs. MOICs are attractive to telecommunications
    equipment manufacturers because they reduce discrete component count,
    speed up the assembly process, increase system reliability and lower
    system costs. The Company is designing and manufacturing additional
    integrated components and modules to meet the evolving needs of its
    customers.     
 
  . HIGH QUALITY, RELIABLE PRODUCTS. E-Tek has a reputation and proven track
    record of providing high quality, reliable passive optical components
    that are a mission critical element of telecommunications systems. The
    Company has attained high ratings in internal and external quality
    assurance evaluations and has been ISO 9001 certified since 1995. The
    Company's ability to design and manufacture quality products has enabled
    it to successfully penetrate high-growth markets such as the submarine
    optical systems market which requires components that can operate
    reliably in an undersea environment where maintenance is extremely
    expensive.
 
  . VALUE-ADDED CUSTOMER RELATIONSHIPS. E-Tek has established strong customer
    relationships with certain telecommunication equipment manufacturers. The
    Company works closely with these customers from the initial product
    design stage through the manufacturing process. This ongoing level of
    interaction enables the Company to better align its product development
    efforts with its customers' evolving product needs.
 
 
                                      33
<PAGE>
 
  . SCALABLE MANUFACTURING CAPABILITIES. Telecommunications equipment
    manufacturers increasingly require a high volume supply of components
    with shorter lead times. E-Tek has invested in expanding manufacturing
    capacity and developing proprietary manufacturing processes and tools
    that enable volume production of a broad array of optical components and
    modules. The Company's large, skilled work force can be reallocated to
    different product lines in response to changes in product and volume
    demands. The combination of the Company's flexible manufacturing process
    and highly trained work force helps to ensure the reliable delivery of
    large orders to its customers.
 
THE E-TEK STRATEGY
 
  E-Tek's strategy is to leverage its market leadership to provide a broad
range of high quality components in large volumes for current and next
generation optical networking systems. Key elements of this strategy include:
 
  . MAINTAIN AND EXPAND LEADERSHIP IN OPTICAL COMPONENT TECHNOLOGY. The
    Company intends to continue to invest in new product development and
    product enhancements that will drive the growth of optical systems and
    will provide additional competitive advantages. As of June 30, 1998, the
    Company had 42 U.S. patents issued and 24 U.S. and 18 foreign patent
    applications pending. The Company currently focuses its product
    development efforts on components for strategic growth areas such as WDM,
    EDFAs and optical switching.
 
  . DESIGN AND BUILD INCREASINGLY INTEGRATED COMPONENTS AND MODULES. The
    Company intends to leverage its design and packaging expertise to
    manufacture value-added integrated components and modules. The Company
    believes that there is growing demand from telecommunications equipment
    manufacturers for more highly integrated components. Integration provides
    many benefits to the Company's customers, including cost reductions as
    well as performance and reliability improvements. In addition, these
    integrated components allow telecommunications equipment manufacturers to
    design smaller systems than can be more easily manufactured.
 
  . STRENGTHEN EXISTING AND DEVELOP NEW CUSTOMER RELATIONSHIPS. The Company
    believes that strong customer relationships are a competitive advantage
    that enable it to more effectively target its product development and
    manufacturing efforts. The Company has established relationships with key
    telecommunications equipment manufacturers by working as a partner to
    solve their product needs. The Company intends to strengthen its existing
    customer relationships by continuing to deliver a high level of value-
    added service and leverage its reputation for high quality products to
    penetrate new key accounts.
 
  . ENHANCE MANUFACTURING CAPABILITIES. Telecommunications equipment
    manufacturers are increasingly demanding higher volumes of components
    with shorter delivery lead times and are requiring higher quality and
    lower cost components. To meet these demands, the Company is increasing
    its manufacturing capacity, investing in automated manufacturing
    processes and establishing lower cost offshore manufacturing facilities.
 
  . TARGET ATTRACTIVE SEGMENTS OF THE OPTICAL NETWORKING MARKET. The Company
    intends to leverage its expertise to strengthen its position in the
    terrestrial and submarine long-haul markets as well as penetrate new
    markets, such as metropolitan area networks. The Company believes that
    technology advancements and cost reductions in optical components and
    modules will enable the continued growth of optical networking into
    markets beyond established terrestrial and submarine long-haul
    applications.
 
  . EXPAND SALES AND MARKETING EFFORTS. The nature of the target customer
    base for the Company's optical components and modules requires a focused
    sales and marketing effort. The Company believes it is necessary to
    expand these efforts to improve service to existing customers and
    effectively target new customers. The Company intends to selectively
    expand its
 
                                      34

   direct sales force and independent sales representatives network to pursue
   additional customer opportunities.
 
TECHNOLOGY AND PRODUCTS
 
  Fiber optic systems manufactured by the Company's customers are used to
transmit, amplify, isolate, route, monitor and receive optical signals, or
wavelengths. The performance of optical components is determined by the
quality and processing of raw materials and the quality of "packaging," which
includes coating, fiber alignment and encapsulation into a functional
component. The Company believes that its capabilities in these areas enable it
to produce components with higher levels of performance, reliability and
management and control of optical signals.
 
  The Company's technological expertise allows it to be a leading provider of
passive components for fiber optic systems and subsystems, including WDM
systems and EDFAs. The following diagram illustrates where the Company's
components are used in WDM systems and EDFAs:
 
[The graphics shown in this section show a schematic of a wavelength division
multiplexing (WDM) system containing an Erbium Doped Fiber Amplifier (EDFA)
and shows the various components contained in the system, with the components
manufactured or packaged by the Company indicated by shading.]
 
  The Company's products are divided into five main categories: optical
isolators, WDM components and modules, couplers, MOICs and other products.
Prices vary by product line but typically range from $200 for a simple
component to $5,000 or more for more complex products.
   
  OPTICAL ISOLATORS. The Company began manufacturing isolators in 1989, and
currently offers a wide range of isolator products, including a recently
introduced high reliability isolator for submarine networks. Isolators act as
a one-way valve for wavelengths. Since optical signals travel along a fiber in
either direction, any disturbance in the fiber can cause a portion of the
signal traveling in one direction to reflect in the opposite direction. These
reflected signals can cause interference in the network. An optical isolator
prevents the reflected signals from traveling past it in the wrong direction
while still allowing the unimpeded passage of signals in the original
direction. In the basic form of the isolator product, a short section of
optical fiber is attached with micron-scale precision to a lens to expand the
optical signal to a parallel beam. Attached to this assembly are small
crystals with optical asymmetry to direct the beam along the optical path and
to divert any light traveling in the reverse     
 
                                      35
<PAGE>
 
direction off to the side. A lens attached to a second short section of
optical fiber collects the light in the beam.
 
  The key performance parameters for an isolator are the percentage of the
original light in the first fiber that passes to the second and the amount of
residual light that passes from the second fiber back to the first. The
performance parameters are directly affected by the skill employed in the
optical design, the ability to secure precision parts and the procedures used
to assemble the parts with exactness. The Company believes its competence in
manufacturing optical isolators with uniformly high percentages of passed
through light and exceedingly small residual light is a key strength.
 
  WDM COMPONENTS AND MODULES. Since 1995, the Company has produced WDM
components and modules, including multiplexers, de-multiplexers, optical
add/drops and gain flattening filters. A WDM multiplexer combines light
sources of different wavelengths for simultaneous transmission along a single
fiber. The combining and separating of wavelengths can be accomplished in
several ways, one of which involves building a WDM component similar in design
and manufacturing process to the optical isolator. In this WDM component,
optically asymmetric crystals used in an isolator are replaced with thin
dielectric filters that enable the passage of specific optical wavelengths and
the reflection of others. These WDM components are then cascaded and spliced
together to create WDM multiplexer and de-multiplexer modules. The key
performance parameters are the efficiency with which the individual
wavelengths are directed to (and only to) the proper fiber section. The
Company believes that it has leading-edge capability in the design and
packaging of dielectric thin-film filter technology.
   
  COUPLERS. Since 1991, the Company has manufactured several types of
couplers, including wideband and narrowband tree and star couplers, two window
wideband couplers, ultra-low PDL couplers, and single-fusion 1x3 and 1x4
couplers. A coupler is used to combine and/or split optical signals. Couplers
are often used to tap off a small portion of a light stream for monitoring
purposes or to distribute the signal to multiple points. If the portion tapped
is approximately half, the component is typically called a fiber coupler. If
the portion is small (a few percent), the product is referred to as an optical
tap. In either case, the function can be performed with the same technology--
fusing two fibers together with the proper spacing to achieve the desired
crossing of light from the main fiber to the branching fiber. The Company has
developed a new, patented technology (Unifuse) which it believes produces more
robust and reliable taps and couplers.     
   
  MICRO-OPTIC INTEGRATED COMPONENTS. MOICs are modules that integrate two or
more optical component functions into a single package. These functions
include, but are not limited to, isolator, WDM and tap coupler functions. For
example, the Company recently introduced a product that combines tap coupler
and isolator functions into a single module for use in EDFAs. This integration
reduces the total component count in a system and provides many benefits for
the Company's customers, including reductions in inventory and the physical
dimensions of the subsystem or system and production costs, as well as
improvements in performance and reliability. The Company designs and
manufactures a range of MOICs for a variety of applications.     
 
  OTHER. The Company manufactures a variety of other components and modules
that perform various functions within an optical system. These products
include attenuators, circulators, mechanical switches and laser controllers.
The Company also has a decade of experience in making assembly and test
equipment for internal use as well as for external sale. Recent products in
this category emphasize the generation and control of the multiple wavelengths
of laser light needed to test and evaluate broad-spectrum optical assemblies
such as fiber amplifiers.

CUSTOMERS
   
  The Company sells its products primarily to telecommunications equipment
manufacturers. Customers that have purchased more than $500,000 of E-Tek's
products in fiscal 1998 include:     
 
  Alcatel ITS, Inc.                      NEC Corporation
  Alcatel Network Systems, Inc.          Northern Telecom Limited
  Alcatel Submarine Networks, Limited    Pirelli Cable Corp.
  CIENA Corporation                      Pirelli Cavi SpA
  Corning, Inc.                          Cables Pirelli SA
  Hewlett-Packard Company                Tyco Submarine Systems Ltd.
  Lucent Technologies Inc.               Williams Communications Group
     
  MCI Communications Corporation     
   
  The Company has established strong relationships with certain
telecommunications equipment manufacturers. The Company works closely with
these customers from the initial product design through the manufacturing
process to delivery of the final product. This ongoing level of interaction
enables the Company to better align its product development efforts with its
customers' evolving product needs.     
   
  A small number of customers have historically accounted for a substantial
portion of the Company's net revenues. Sales to Alcatel, Pirelli and Corning
represented approximately 30.2%, 16.5% and 14.3%, respectively, of the
Company's net revenues for fiscal 1998. Sales to the Company's five largest
customers represented approximately 73.4% and 77.5% of the Company's net
revenues for fiscal 1998 and the fourth quarter of fiscal 1998, respectively.
The loss of any key customer could have a material adverse effect on the
Company's business, financial condition and results of operations. See "Risk
Factors--Dependence on a Limited Number of Major Customers."     
 
RESEARCH AND DEVELOPMENT
 
  The Company currently has 51 employees engaged in research and development,
including 27 engineers with advanced degrees, 12 of whom have Ph.D.s. The
Company seeks to continue to develop core technologies with applications for
product solutions in each of the Company's target markets, which enables the
Company to leverage its ability to address various component markets with a
relatively focused investment in research and development. The Company's
research and development expenses for fiscal 1998 and fiscal 1997 were
approximately $7.7 million and $4.0 million, respectively. The Company plans to
increase its research and development budget and staffing levels in fiscal
1999. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
MANUFACTURING
 
  The Company currently manufactures and packages its component products at its
facilities in San Jose, California. The Company's in-house manufacturing
capabilities include product design, optical assembly, integration and testing
of its component products. The Company maintains a proprietary system of
optical assembly stations located in clean rooms throughout its facilities to
manufacture custom engineered and standard products. By leveraging these
manufacturing skills, the Company seeks to maintain flexible manufacturing
processes designed to meet customer expectations for innovative product
solutions, high volume capacity, high quality and on-time delivery.
 
  Telecommunications equipment manufacturers require high quality and
reliability in the components incorporated into their systems. The Company
emphasizes quality assurance through ongoing staff training and internal
manufacturing systems and procedures throughout the Company's various
manufacturing processes, including the design, assembly, integration, packaging
and test
 
                                       37
<PAGE>
 
functions of these processes. Quality control procedures necessary to meet
increasingly stringent customer demands are in place throughout the Company,
including appropriate levels of incoming inspection and outgoing testing. The
Company has attained high ratings in internal and external evaluations and has
been ISO 9001 certified since 1995.
 
  The raw materials which the Company requires for the manufacture of its
products are generally available from several sources, although a number of
raw materials are available only from sole source suppliers. See "Risk
Factors--Dependence on Suppliers."
   
  To further enhance its manufacturing capabilities and reduce manufacturing
costs, the Company intends to increase its level of manufacturing automation
and expand into additional facilities as required. The Company has recently
increased its capacity by expanding the size of its facilities from
approximately 90,000 square feet to approximately 160,000 square feet. The
Company has been moving portions of its operations, including manufacturing
operations, to this new space as it becomes available. The Company has
financed its facilities expansion through a combination of cash flow from
operations, commercial credit lines and capital lease financing. In addition,
the Company entered into the FibX Joint Venture to build and operate a fiber
optic component manufacturing facility in Taiwan. The Company anticipates that
it will begin manufacturing certain of its mature products at this facility in
1999. See "Risk Factors--Manufacturing and Facilities Expansion Risks."     
 
SALES AND MARKETING
   
  The Company markets and sells its products primarily through a network of
seven domestic and 22 international sales representatives and distributors.
The Company's sales representatives and distributors are independent
organizations that generally have exclusive geographic territories and are
generally compensated on a commission basis.     
   
  The Company also employs a 32 person sales and marketing staff located in
San Jose, which manages key customer accounts and supports the Company's sales
representatives and distributors. The Company's customers often have unique
technical specifications and performance requirements for components and
typically require specific product designs. As a result, the Company's sales
efforts are dependent on close cooperation between the Company's independent
sales representatives and distributors and the Company's in-house personnel.
    
  In support of its selling effort, the Company conducts marketing programs
intended to position and promote its products within the telecommunications
industry. Marketing personnel coordinate the Company's participation in trade
shows and design and implement the Company's advertising efforts. In addition,
the marketing group gathers and maintains market research and tracks industry
trends and developments in order to anticipate customer needs for new products
and develop pricing strategies.
 
COMPETITION
   
  The market for fiber optic components is intensely competitive and
characterized by rapidly changing technology. The Company currently
experiences competition from various companies including, among others: (i)
FDK Corporation, Kyocera Corp. and Shinkosha K.K. in isolators, (ii) Lucent,
Corning, and JDS FITEL, Inc. in WDM components and modules and (iii) ADC
Telecommunications, Inc. and Gould Electronics, Inc. in couplers. The Company
also faces competition from numerous smaller companies. Many of the Company's
current and potential competitors have significantly greater financial,
technical, marketing, purchasing and other resources than the Company, and as
a result, may be able to respond more quickly to new or emerging technologies
or standards and to changes in customer requirements, to devote greater
resources to the development, promotion and sale of products, or to deliver
competitive products at a lower prices. Many of these competitors manufacture
their products in countries offering significantly lower labor costs than in
the United States.     
 
                                      38
<PAGE>
 
   
  Existing and potential customers are also current or potential competitors
of the Company. These companies may develop or acquire additional competitive
products or technologies in the future and thereby reduce or cease their
purchases from the Company. For example, one of the Company's customers
recently purchased a fiber optic component manufacturer and began
manufacturing a product internally that it formerly purchased from the
Company. The Company may also face competition in the future from these and
other parties that develop fiber optic components based upon the technologies
similar to or different from the technologies employed by the Company. The
Company expects competition in general to intensify substantially, and further
expects competition to be broadly based on varying combinations of
manufacturing capacity, ability to deliver on-time, technical features,
quality and reliability, customization to customer specifications, strength of
distribution channels, pricing, and comprehensiveness of product offerings.
There can be no assurance that the Company will be able to compete
successfully with its existing or new competitors or that competitive
pressures faced by the Company will not result in lower prices for the
Company's products, loss of market share, or reduced gross margins, any of
which could materially and adversely affect the Company's business, financial
condition and results of operations.     
 
PATENTS AND INTELLECTUAL PROPERTY RIGHTS
   
  The Company's success will depend, in part, on its ability to protect its
intellectual property. The Company relies primarily on patent, copyright,
trademark and trade secret laws, as well as nondisclosure agreements and other
methods to protect its proprietary technologies and processes. There can be no
assurance that such measures will provide meaningful protection for the
Company's proprietary technologies and processes. As of June 30, 1998, the
Company had 42 U.S. patents issued and 24 U.S. and 18 foreign patent
applications pending. These patents expire between 2007 and 2016. There can be
no assurance that any patent will issue as a result of these applications or
future applications or, if issued, that any patent claims allowed will be
sufficiently broad to protect the Company's technology. In addition, there can
be no assurance that any existing or future patents will not be challenged,
invalidated or circumvented, or that any right granted thereunder would
provide meaningful protection to the Company. The failure of any patents to
provide protection to the Company's technology would make it easier for the
Company's competitors to offer similar products. The Company also generally
enters into confidentiality agreements with its employees and strategic
partners, and generally controls access to and distribution of its
documentation and other proprietary information. Despite these precautions, it
may be possible for a third party to copy or otherwise obtain and use the
Company's products or technology without authorization, develop similar
technology independently or design around the Company's patents. In addition,
effective patent, copyright, trademark and trade secret protection may be
unavailable or limited outside of the United States, Europe and Japan. There
can be no assurance that the Company will be able to obtain any meaningful
intellectual property protection in such countries and territories. Further,
the Company occasionally incorporates the intellectual property of its
customers into its designs, and the Company has certain obligations with
respect to the non-use and non-disclosure of such intellectual property. There
can be no assurance that the steps taken by the Company to prevent
misappropriation or infringement of the intellectual property of the Company
or its customers will be successful. Moreover, litigation may be necessary in
the future to enforce the Company's intellectual property rights, to protect
the Company's trade secrets or to determine the validity and scope of
proprietary rights of others, including its customers. Such litigation could
result in substantial costs and diversion of the Company's resources and could
have a material adverse effect on the Company's business, financial condition
and results of operations.     
 
  The telecommunications equipment industry is characterized by vigorous
protection and pursuit of intellectual property rights. From time to time, the
Company has received, and may continue to receive in the future, notices of
claims of infringement of other parties' proprietary rights. There can be no
assurance that the Company will prevail in actions alleging infringement by
the Company of third-party
 
                                      39
<PAGE>
 
patents or the invalidity of the patents held by the Company will not be
asserted or prosecuted against the Company, or that any assertions of
infringement or prosecutions seeking to establish the invalidity of Company-
held patents will not materially and adversely affect the Company's business,
financial condition and results of operations. For example, in a patent or
trade secret action, an injunction could issue against the Company requiring
that the Company withdraw certain products from the market or necessitating
that certain products offered for sale or under development be redesigned. The
Company has also entered into certain indemnification obligations in favor of
its customers and strategic partners that could be triggered upon an
allegation or finding of the Company's infringement of other parties'
proprietary rights. Irrespective of the validity or successful assertion of
such claims, the Company would likely incur significant costs and diversion of
its resources with respect to the defense of such claims, which could also
have a material adverse effect on the Company's business, financial condition
and results of operations. To address any potential claims or actions asserted
against the Company, the Company may seek to obtain a license under a third
party's intellectual property rights. There can be no assurance that under
such circumstances a license would be available on commercially reasonable
terms, if at all.
   
  Substantial inventories of intellectual property are held by a few industry
participants, such as Lucent, Nortel and certain major universities and
research laboratories. This concentration of intellectual property in the
hands of a few major entities also poses certain risks to the Company in
seeking to hire qualified personnel. The Company has on a few occasions
recruited such personnel from such entities. There can be no assurance that
these entities or others will not claim the misappropriation or infringement
of their intellectual property, particularly when and if employees of these
entities leave to work for the Company. There can be no assurance that the
Company will be able to avoid litigation in the future, particularly if new
employees join the Company after having worked for a competing company. Such
litigation could be very expensive to defend, regardless of the merits of the
claims, and could have a material adverse effect on the Company's business,
financial condition and results of operations.     
 
EMPLOYEES
 
  As of June 30, 1998, the Company employed 657 persons, of whom 525 were
primarily engaged in manufacturing, 51 were engaged in research and
development, 32 were engaged in sales, marketing and technical support and 49
were engaged in administration. The Company's employees are not represented by
any collective bargaining agreement, and the Company has not experienced a
work stoppage. The Company believes its employee relations are good.
 
FACILITIES
 
  The Company's principal offices and facilities are located in San Jose,
California. The Company owns three buildings in San Jose aggregating
approximately 180,000 square feet, 20,000 square feet of which is leased to a
third party through May 2001, as well as five acres of vacant land nearby. The
Company also leases 5,148 square feet in close proximity to its San Jose
facilities. This lease expires on March 31, 2000. The Company believes that
its existing facilities are adequate to meet its current needs.
 
LEGAL PROCEEDINGS
 
  The Company has in the past received notifications alleging that it is
infringing the intellectual property rights of third parties. The Company is
involved in disputes and litigation in the normal course of its business. The
Company does not believe that the outcome of any of these infringement
allegations or these disputes or litigation will have a material adverse
effect on the Company's business, financial condition or results of
operations.

(4) Potential realizable values are net of exercise price, but before taxes
    associated with exercise. Amounts represent hypothetical gains that could
    be achieved for the respective options if exercised at the end of the
    option term. The assumed 0%, 5% and 10% rates of stock price appreciation
    are provided in accordance with rules of the Securities and Exchange
    Commission and do not represent the Company's estimate or projection of
    the future Common Stock price. The assumed rate of appreciation of 0%
    indicates the value at the effective date of this offering based on the
    deemed value for financial accounting purposes, less the exercise price.
    Actual gains, if any, on stock option exercises are dependent on the
    future performance of the Common Stock, overall market conditions and the
    option holders' continued employment through the vesting period. This
    table does not take into account any appreciation in the price of the
    Common Stock from the date of grant to date.     
   
(5) All such options were immediately exercised by Mr. Fitzpatrick on the date
    of grant, but 2,260,000 shares acquired upon such exercise are subject to
    a right of repurchase by the Company which lapses periodically over a
    four-year vesting period which commenced in November 1997, and 188,333
    shares acquired upon such exercise are subject to a right of repurchase by
    the Company which lapses periodically over a five-year vesting period and
    on an accelerated basis upon the achievement of certain milestones.

(1) All options are immediately exercisable at the date of grant, but shares
    purchased upon exercise of options are subject to repurchase by the
    Company based upon a prescribed vesting schedule.
(2) Calculated on the basis of the fair market value of the Company's Common
    Stock as of June 30, 1998 ($10.00 per share), as determined by the
    Company's Board of Directors, less the aggregate exercise price.
   
(3) Includes 2,260,000 shares owned by Mr. Fitzpatrick that are subject to a
    right of repurchase by the Company which lapses periodically over a four-
    year vesting period which commenced in November 1997, and 188,333 shares
    owned by Mr. Fitzpatrick that are subject to a right of repurchase by the
    Company which lapses periodically over a five-year vesting period and on
    an accelerated basis upon the achievement of certain milestones. As
    calculated in accordance with the rules of the Securities and Exchange
    Commission, there was no "value realized" by Mr. Fitzpatrick upon the
    exercise of such options because the aggregate exercise price of such
    options was equal to the aggregate fair market value of such shares on the
    date of exercise as determined by the Company's Board of Directors.

STOCK PLANS
 
  1997 EQUITY INCENTIVE PLAN
 
  The Company's 1997 Equity Incentive Plan (the "1997 Plan") was adopted by
the Board of Directors and approved by the stockholders in June 1997. A total
of 10,555,555 shares of Common Stock have been reserved for issuance under the
1997 Plan. As of June 30, 1998, 1,855,535 shares of Common Stock subject to
repurchase by the Company had been issued upon exercise of options, 1,418,717
shares of Common Stock not subject to repurchase by the Company had been
issued upon exercise of options, and 3,050,198 shares of Common Stock options
were outstanding at a weighted average exercise price of $4.05. The Board of
Directors has determined that no further options will be granted under the
1997 Plan after the completion of this offering. Unless terminated sooner, the
1997 Plan will terminate automatically in June 2007.
 
  The 1997 Plan provides for the grant of incentive stock options, within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), to employees of the Company and for the grant of nonstatutory stock
options and restricted stock awards to employees, directors and consultants of
the Company.
 
  Options granted under the 1997 Plan must generally be exercised within three
months after the end of an optionee's status as an employee, director or
consultant of the Company, or within twelve
 
                                      47
<PAGE>
 
months after such optionee's termination by death or disability, but in no
event later than the expiration of the option term. In the event an optionee
is terminated for cause, his or her option shall terminate immediately.
 
  Options and restricted stock awards granted under the 1997 Plan are
generally not transferable by the optionee other than by will or by the laws
of descent and distribution, and each option and restricted stock award is
exercisable during the lifetime of the optionee only by such optionee. The
1997 Plan provides that in the event of a (i) dissolution or liquidation of
the Company, (ii) certain mergers or consolidations or (iii) a sale of all or
substantially all of the assets of the Company, each option and restricted
stock award shall be assumed or an equivalent option or award substituted for
by the successor corporation. If the outstanding options and restricted stock
awards are not assumed or substituted for by the successor corporation, such
options and restricted stock awards shall terminate.
 
  1997 EXECUTIVE EQUITY INCENTIVE PLAN
 
  The Company's 1997 Executive Equity Incentive Plan (the "1997 Executive
Plan") was adopted by the Board of Directors in October 1997 and approved by
the stockholders in December 1997. A total of 4,444,445 shares of Common Stock
have been reserved for issuance under the 1997 Executive Plan. As of June 30,
1998, 4,025,000 shares of Common Stock subject to repurchase by the Company
had been issued upon exercise of options granted under the 1997 Executive
Plan. The Board of Directors has determined that no further options will be
granted under the 1997 Executive Plan after the completion of this offering.
Unless terminated sooner, the 1997 Executive Plan will terminate automatically
in October 2007.
 
  The 1997 Executive Plan provides for the grant of incentive stock options,
within the meaning of Section 422 of the Code, non-qualified stock options,
restricted stock awards and stock bonuses (each, an "Award") to employees of
the Company who are also directors or officers of the Company.
 
  Options granted under the 1997 Executive Plan must generally be exercised
within three months after the end of an optionee's status as an employee,
director or consultant of the Company, or within twelve months after such
optionee's termination by death or disability, but in no event later than the
expiration of the option term. In the event an optionee is terminated for
cause, his or her option shall terminate immediately.
 
  Awards granted under the 1997 Executive Plan are generally not transferable
by the optionee other than by will or by the laws of descent and distribution,
and each Award is exercisable during the lifetime of the optionee only by such
optionee. The 1997 Executive Plan provides that in the event of a (i)
dissolution or liquidation of the Company, (ii) certain mergers or
consolidations or (iii) a sale of all or substantially all of the assets of
the Company, each Award shall be assumed or an award substituted for by the
successor corporation. If the outstanding Awards are not assumed or
substituted for by the successor corporation, vesting of the Awards shall
accelerate immediately prior to the consummation of such transaction and shall
terminate on the consummation of such transaction.
 
  1998 STOCK PLAN
 
  The Company's 1998 Stock Plan (the "1998 Plan") was adopted by the Board of
Directors in August 1998 and approved by the stockholders in September 1998.
As of the date of this Prospectus, no options have been granted under the 1998
Plan.
 
  The 1998 Plan provides for the grant of incentive stock options to employees
(including officers and employee directors) and for the grant of nonstatutory
stock options and stock purchase rights ("SPRs") to employees, directors and
consultants. A total of (i) 3,000,000 shares of Company
 
                                      48
<PAGE>
 
   
Common Stock (plus shares which have been reserved but unissued under the
Company's 1997 Plan), (ii) any shares returned to the 1997 Plan as a result of
termination of options or repurchase of shares by the Company and (iii) annual
increases to be added on the date of each annual meeting of stockholders
commencing in 1999 equal to the lesser of 3,000,000 shares, 4% of the
outstanding shares, or such lesser amount as may be determined by the Board of
Directors, are currently reserved for issuance pursuant to the 1998 Plan.
Unless terminated sooner, the 1998 Plan will terminate automatically in
September 2008.     
   
  The administrator of the 1998 Plan has the power to determine the terms of
the options or SPRs granted, including the exercise price of the option or
SPR, the number of shares subject to each option or SPR, the exercisability
thereof, and the form of consideration payable upon such exercise. In
addition, the Administrator has the authority to amend, suspend or terminate
the 1998 Plan, provided that no such action may affect any share of Company
Common Stock previously issued and sold or any option or SPR previously
granted under the 1998 Plan.     
 
  Options and SPRs granted under the 1998 Plan are generally not transferable
by the optionee, and each option and SPR is exercisable during the lifetime of
the optionee only by such optionee. Options granted under the 1998 Plan must
generally be exercised within three months after the end of an optionee's
status as an employee, director or consultant of the Company, or within twelve
months after such optionee's termination by death or disability, but in no
event later than the expiration of the option term.
 
  In the case of SPRs, unless the Administrator determines otherwise, the
restricted stock purchase agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's employment or consulting relationship with the Company for any
reason (including death or disability). The purchase price for shares
repurchased pursuant to the restricted stock purchase agreement shall be the
original price paid by the purchaser and may be paid by cancellation of any
indebtedness of the purchaser to the Company. The repurchase option shall
lapse at a rate determined by the Administrator.
 
  The exercise price of all incentive stock options granted under the 1998
Plan must be at least equal to the fair market value of the Company Common
Stock on the date of grant. The exercise price of nonstatutory stock options
and SPRs granted under the 1998 Plan is determined by the Administrator, but
with respect to nonstatutory stock options intended to qualify as
"performance-based compensation" within the meaning of Section 162(m) of the
Code, the exercise price must be at least equal to the fair market value of
the Company Common Stock on the date of grant. With respect to any participant
who owns stock possessing more than 10% of the voting power of all classes of
the Company's outstanding capital stock, the exercise price of any incentive
stock option granted must be at least equal to 110% of the fair market value
on the grant date and the term of such incentive stock option must not exceed
five years. The term of all other options granted under the 1998 Plan may not
exceed ten years.
 
  The 1998 Plan provides that in the event of a merger of the Company with or
into another corporation, or a sale of substantially all of the Company's
assets, each option and SPR shall be assumed or an equivalent option
substituted for by the successor corporation. If the outstanding options and
SPRs are not assumed or substituted for by the successor corporation, the
Administrator shall provide for the optionee to have the right to exercise the
option or SPR as to all of the optioned stock, including shares as to which it
would not otherwise be exercisable. If the Administrator makes an option or
SPR exercisable in full in the event of a merger or sale of assets, the
Administrator shall notify the optionee that the option or SPR shall be fully
exercisable for a period of fifteen (15) days from the date of such notice,
and the option or SPR will terminate upon the expiration of such period.

  1998 EMPLOYEE STOCK PURCHASE PLAN
 
  The Company's 1998 Employee Stock Purchase Plan (the "1998 Purchase Plan")
was adopted by the Board of Directors in August 1998 and approved by the
stockholders in September 1998. A total of 750,000 shares of Company Common
Stock has been reserved for issuance under the 1998 Purchase Plan, plus annual
increases equal to the lesser of (i) 750,000 shares, (ii) 1% of the
outstanding shares on such date, or (iii) such lesser amount as may be
determined by the Board of Directors. As of the date of this Prospectus, no
shares have been issued under the 1998 Purchase Plan.
 
  The 1998 Purchase Plan, which is intended to qualify under Section 423 of
the Code, contains consecutive, overlapping, twenty-four month offering
periods. Each offering period includes four six-month purchase periods. The
offering periods generally start on the first trading day on or after May 1
and November 1 of each year, except for the first such offering period which
commences on the first trading day on or after the effective date of this
offering and ends on the last trading day on or before October 31, 2000.
   
  Employees are eligible to participate if they are customarily employed by
the Company or any participating subsidiary for at least 20 hours per week and
more than five months in any calendar year. However, any employee who (i)
immediately after any grant owns stock possessing 5% or more of the total
combined voting power or value of all classes of the capital stock of the
Company or (ii) whose rights to purchase stock under all employee stock
purchase plans of the Company accrues at a rate which exceeds $25,000 worth of
stock for each calendar year may not be granted an option to purchase stock
under the 1998 Purchase Plan. The 1998 Purchase Plan permits participants to
purchase Common Stock through payroll deductions of up to 10% of the
participant's "compensation." Compensation is defined as the participant's
base straight time gross earnings and commissions, including payments for
overtime, shift premiums, incentive compensation, incentive payments, bonuses
and other compensation. The maximum number of shares a participant may
purchase during a single purchase period is 5,000 shares.     
 
  Amounts deducted and accumulated by the participant are used to purchase
shares of Common Stock at the end of each purchase period. The price of stock
purchased under the 1998 Purchase Plan is generally 85% of the lower of the
fair market value of the Common Stock (i) at the beginning of the offering
period or (ii) at the end of the purchase period. 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, the participants will be withdrawn from
the current offering period following exercise and automatically re-enrolled
in a new offering period. The new offering period will use the lower fair
market value as of the first date of the new offering period to determine the
purchase price for future purchase periods. Participants may end their
participation at any time during an offering period, and they will be paid
their payroll deductions to date. Participation ends automatically upon
termination of employment with the Company.
 
  Rights granted under the 1998 Purchase Plan are not transferable by a
participant other than by will, the laws of descent and distribution, or as
otherwise provided under the 1998 Purchase Plan. The 1998 Purchase Plan
provides that, in the event of a merger of the Company with or into another
corporation or a sale of substantially all of the Company's assets, each
outstanding right to purchase stock may be assumed or substituted for by the
successor corporation. If the successor corporation refuses to assume or
substitute for the outstanding rights to purchase stock, the offering period
then in progress will be shortened and a new exercise date will be set.
 
  The Board of Directors has the authority to amend or terminate the 1998
Purchase Plan, except that no such action may adversely affect any outstanding
rights to purchase stock under the 1998 Purchase Plan, provided that the Board
of Directors may terminate an offering period on any exercise
 
                                      50
<PAGE>
 
date if the Board determines that the termination of the 1998 Purchase Plan is
in the best interests of the Company and its stockholders. Notwithstanding
anything to the contrary, the Board of Directors may in its sole discretion
amend the 1998 Purchase Plan to the extent necessary and desirable to avoid
unfavorable financial accounting consequences by altering the purchase price
for any offering period, shortening any offering period or allocating
remaining shares among the participants. The 1998 Purchase Plan will terminate
in August 2008, unless sooner terminated by the Board of Directors.
 
  1998 DIRECTOR OPTION PLAN
 
  The 1998 Director Option Plan (the "Director Plan") was adopted by the Board
of Directors in August 1998 and approved by the stockholders in September
1998. The Director Plan provides for the grant of nonstatutory stock options
to non-employee directors who are not also partners or members of any venture
capital investor which owns securities of the Company holding more than five
percent (5%) of the total voting power of the Company's outstanding capital
stock ("Outside Directors"). The Director Plan has a term of ten years, unless
terminated sooner by the Board. A total of 250,000 shares of Company Common
Stock, plus an annual increase equal to the optioned stock underlying options
granted in the immediately preceding year (or such lesser amount as may be
determined by the Board of Directors), have been reserved for issuance under
the Director Plan. As of the date of this Prospectus, no options have been
granted under the Director Plan.
   
  The Director Plan provides that each new Outside Director shall
automatically be granted an option to purchase 40,000 shares of Company Common
Stock (the "First Option") on the date which such person first becomes a non-
employee director. In addition to the First Option, each Outside Director
shall automatically be granted an option to purchase 10,000 shares (a
"Subsequent Option") on the date which is two (2) days after the Company's
financial results for the preceding fiscal year are announced to the public,
if on such date he or she shall have served on the Board of Directors for at
least six months. Each First Option and Subsequent Option shall have a term of
10 years. The shares subject to the First Option and Subsequent Option shall
vest as to 1/4 of the optioned stock one year from the date of grant, and 1/48
of the optioned stock each month thereafter, provided the person continues to
serve as an Outside Director on such dates. The exercise price of each First
Option and each Subsequent Option shall be 100% of the fair market value per
share of the Company Common Stock on the date of grant.     
 
  In the event of a merger of the Company or the sale of substantially all of
the assets of the Company, each option granted to an Outside Director under
the Director Plan shall become fully vested and exercisable for a period of
thirty (30) days from the date the Board notifies the optionee of the option's
full exercisability, after which period the option shall terminate. Options
granted under the Director Plan must be exercised within three months of the
end of the optionee's tenure as a director of the Company, or within twelve
months after such director's termination by death or disability, but in no
event later than the expiration of the option's ten year term. No option
granted under the Director Plan is transferable by the optionee other than by
will or the laws of descent and distribution, and each option is exercisable,
during the lifetime of the optionee, only by such optionee.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
   
  The Company's Certificate of Incorporation provides that a director of the
Company shall not be personally liable for monetary damages to the Company or
its stockholders for a breach of fiduciary duty as a director, except for
liability as a result of (i) a breach of the director's duty of loyalty to the
Company or its stockholders, (ii) acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) an act
related to the unlawful stock repurchase or payment of a dividend under
Section 174 of the Delaware General Corporation Law or (iv) transactions from
which the director derived an improper personal benefit. Such limitation of
liability does not affect the availability of equitable remedies such as
injunctive relief or rescission.     
 
                                      51
<PAGE>
 
  The Company's Certificate of Incorporation also authorizes the Company to
indemnify its officers, directors and other agents to the full extent
permitted under the Delaware General Corporation Law. The Company has entered
into separate indemnification agreements with its directors and executive
officers that may, in some cases, provide broader indemnification protection
than the specific indemnification provisions contained in the Delaware General
Corporation Law. The indemnification agreements require the Company, among
other things, to indemnify such officers and directors against certain
liabilities that may arise by reason of their status or service as officers or
directors (other than liabilities arising from willful misconduct of a
culpable nature), and to advance their expenses incurred as a result of any
proceeding against them as to which they could be indemnified. In addition,
these agreements extend similar indemnification arrangements to stockholders
whose representatives serve as directors of the Company.
 
  At present, there is no pending litigation or proceeding involving a
director, officer, employee or agent of the Company where indemnification will
be required or permitted. The Company is not aware of any threatened
litigation or proceeding which may result in a claim for such indemnification.

<PAGE>
 
                             CERTAIN TRANSACTIONS
 
  Since July 1, 1995, there has not been any transaction or series of similar
transactions to which the Company was or is a party in which the amount
involved exceeded or exceeds $60,000 and in which any director, executive
officer, holder of more than 5% of any class of the Company's voting
securities, or any member of the immediate family of any of the foregoing
persons had or will have a direct or indirect material interest, other than
the transactions described below and under "Management--Employment Agreements
and Change of Control Arrangements" and "--Limitation of Liability and
Indemnification."
 
RECAPITALIZATION
 
  On July 23, 1997, the Company completed a recapitalization (the
"Recapitalization"). Prior to the Recapitalization, the authorized capital
stock of the Company consisted of 1,000,000 shares of Common Stock of which
101,271 shares were issued and outstanding, all of which were beneficially
owned by Jing Jong Pan and Theresa Pan (the "Founders"). In connection with
the Recapitalization, the Company consummated a stock split which resulted in
the conversion of the 101,271 outstanding shares of Common Stock into
50,000,000 shares of Common Stock. The Company then (i) authorized and sold
30,000,000 shares of Convertible Preferred Stock, a controlling stake in the
Company, to certain investors for an aggregate purchase price of $120 million
and (ii) repurchased 30,000,000 shares of Common Stock from the Company's
Founders for $120 million.
   
  The Convertible Preferred Stock has certain rights and privileges, including
the right to receive preferential dividends and participating dividends, the
right to preferential distributions upon a liquidation of the Company, the
ability to require the Company to redeem such shares in certain circumstances,
the right to approve certain actions by the Company, and the right to elect a
majority of the directors of the Company. The Convertible Preferred Stock
issued in the Recapitalization will be converted into Common Stock upon the
closing of this offering and the holders thereof will therefore forfeit any
right to receive accumulated dividends on such Convertible Preferred Stock.
    
  In connection with the Recapitalization, the Company, the purchasers of the
Convertible Preferred Stock and the Founders also entered into a Shareholders
Agreement relating to the ongoing corporate governance of the Company,
including the composition of the Board of Directors and restrictions on
transfer of the stock of the Company, including rights of first refusal and
co-sale rights. All such restrictions will terminate upon the closing of this
offering.
 
  In connection with Recapitalization, the Company, the purchasers of
Convertible Preferred Stock and the Founders entered into a Registration
Agreement pursuant to which such shareholders acquired certain registration
rights in respect of the shares of the Company's capital stock acquired in
connection with Recapitalization. See "Description of Capital Stock--
Registration Rights."
 
  Pursuant to the Recapitalization, the Company entered into agreements with
the Founders and with certain other executives of the Company pursuant to
which such persons purchased shares of Common Stock of the Company with the
proceeds of a loan from the Company to such persons.

                         DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
  Upon the closing of this offering, the authorized capital stock of the
Company will consist of 300,000,000 shares of Common Stock, $0.001 par value,
and 25,000,000 shares of undesignated preferred stock ("Preferred Stock"),
$0.01 par value. The following description of the Company's capital stock does
not purport to be complete and is subject to, and qualified in its entirety
by, the terms of the Certificate of Incorporation and Bylaws of the Company,
copies of which have been filed with the Commission as exhibits to the
Company's Registration Statement of which this prospectus forms a part, and by
the applicable provisions of Delaware law.
 
COMMON STOCK
   
  As of September 21, 1998, there were 57,442,498 shares of Common Stock of
the Company outstanding which were held of record by approximately 127
stockholders, as adjusted to reflect the conversion of all convertible
securities into shares of the Company's Common Stock upon the closing of this
offering. Assuming no exercise of the Underwriters' over-allotment option and
no exercise of options to purchase Common Stock after September 21, 1998,
there will be 61,442,498 shares of Common Stock of the Company outstanding
after giving effect to the sale of all the shares of Common Stock of the
Company to be sold in connection with the offering.     
   
  Holders of Common Stock are entitled to one vote per share on all matters to
be voted upon by the stockholders of the Company. Holders of Common Stock do
not have cumulative voting rights under the Company's Certificate of
Incorporation or Bylaws and, therefore, holders of a majority of the shares
voting for the election of directors can elect all of the directors of the
Company, subject to the classified board provisions set forth in the Company's
Certificate of Incorporation. See "Management--Executive Officers and
Directors." In such event, the holders of the remaining shares will not be
able to elect any directors. The shares of Common Stock offered in connection
with this offering, when issued, will be fully paid and nonassessable and will
not be subject to any redemption or sinking fund provisions. Holders of Common
Stock do not have any preemptive, subscription or conversion rights. Holders
of Common Stock 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 rights of preferred stockholders and the terms of any
existing or future agreements between the Company and its debt holders. Since
January 1, 1995, the Company has not declared or paid any cash dividends on
its Common Stock. The Company presently intends to retain future earnings, if
any, for use in the operation and expansion of its business and does not
anticipate paying cash dividends in the foreseeable future. See "Dividend
Policy." In the event of the liquidation, dissolution or winding up of the
Company, the holders of Common Stock are entitled to share ratably 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 Stock
then outstanding.     
 
PREFERRED STOCK
 
  Upon the closing of this offering, the Company will be authorized to issue
25,000,000 shares of Preferred Stock. The Board of Directors has the authority
to issue the Preferred Stock 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 the Company's stockholders. The issuance of Preferred Stock
could have the effect of delaying, deferring or preventing a change in control
of the Company without further action by the stockholders and may adversely
affect the market price, and the voting and other rights, of the holders of
Common Stock. The issuance of Preferred Stock with voting and conversion
rights may adversely affect the voting power of the holders of Common Stock,
including the loss of voting control to others. The Company has no current
plans to issue any shares of Preferred Stock.

ANTI-TAKEOVER EFFECTS OF THE CERTIFICATE OF INCORPORATION, BYLAWS AND DELAWARE
LAW
 
  CERTIFICATE OF INCORPORATION AND BYLAWS
   
  Effective upon the closing of this offering, the Company's Certificate of
Incorporation will provide that the Board of Directors will be divided into
three classes of directors with each class serving a staggered three-year
term. See "Management--Executive Officers and Directors." The classification
system of electing directors may tend to discourage a third party from making
a tender offer or otherwise attempting to obtain control of the Company and
may maintain the incumbency of the Board of Directors, as it generally makes
it more difficult for stockholders to replace a majority of the directors. The
Company's Certificate of Incorporation will also eliminate, upon the closing
of this offering, the right of stockholders to act without a meeting and does
not provide for cumulative voting in the election of directors. These and
other provisions may have the effect of deterring hostile takeovers or
delaying changes in control or management of the Company. The amendment of any
of these provisions would require approval by holders of at least two thirds
of the combined voting power of all of the outstanding Common Stock and
Preferred Stock entitled to vote, unless an amendment is approved by a
majority of the directors of the Company not affiliated with or associated
with any person or entity holding 20% or more of the voting power of the
Company's outstanding capital stock.     
 
  DELAWARE TAKEOVER STATUTE
 
  The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the date that
such stockholder became an interested stockholder, unless: (i) prior to such
date, the board of directors of the corporation approved either the business
combination or the transaction that resulted in the stockholder becoming an
interested stockholder; (ii) upon consummation of the transaction that
resulted in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned (x) by persons
who are directors and also officers and (y) by employee stock plans in which
employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or
exchange offer; or (iii) on or subsequent to such date, the business
combination is approved by the board of directors and authorized at an annual
or special meeting of stockholders, and not by written consent, by the
affirmative vote of at least 66 2/3% of the outstanding voting stock that is
not owned by the interested stockholder.
 
  Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii)
any sale, transfer, pledge or other disposition of 10% or more of the assets
of the corporation involving the interested stockholder; (iii) subject to
certain exceptions, any transaction that results in the issuance or transfer
by the corporation of any stock of the corporation to the interested
stockholder; (iv) any transaction involving the corporation that has the
effect of increasing the proportionate share of any class or series of stock
of the corporation beneficially owned by the interested stockholder; or (v)
the receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or
through the corporation. In general, Section 203 defines an interested
stockholder as any entity or person beneficially owning 15% or more of the
outstanding voting stock of the corporation and any entity or person
affiliated with or controlling or controlled by such entity or person.
 
REGISTRATION RIGHTS
 
  Pursuant to the terms of a Registration Agreement entered into in connection
with the Recapitalization, the holders of a majority of the shares held by
certain investors in the Company at the time of the Recapitalization
("Investors") may demand registration by the Company of all or any
 
                                      59
<PAGE>
 
portion of their shares of Common Stock of the Company in connection with the
sale of such shares by such Investors. Such demand registrations are not
limited in number, but the Company is not obligated to pay the expenses
associated with more than three demand registrations on Form S-1. The managing
underwriter of an offering involving a demand registration may limit the
number of shares to be included in such registration on the basis of market
considerations. Holders of a majority of the shares held by Investors to be
included in a demand registration are entitled to choose the managing
underwriter, if any, of the offering for which the registration is being
effected. The parties to the Registration Agreement are entitled to notice of,
and to participate in, any registration proposed by the Company (other than
registrations on Form S-4 or Form S-8). The managing underwriter of such a
"piggyback" registration involving an underwritten offering may limit the
number of shares of Common Stock of the Company held by the Investors and the
Founders to be included in such registration. The Registration Agreement
contains a lock-up provision pursuant to which the holders of registrable
securities agree not to sell any securities of the Company during (i) the
seven days prior to and (ii)(A) the 180 days after the effectiveness of a
registration statement filed in connection with the Company's initial public
offering or (B) unless the underwriters otherwise agree, the 90 days after the
effectiveness of a registration statement filed in connection with the
Company's next registered public offering or any underwritten registration
(demand or piggyback) of shares of the Company's Common Stock that includes
shares registered pursuant to the rights granted under the Registration
Agreement.

                        SHARES ELIGIBLE FOR FUTURE SALE
   
  Prior to this offering, there has been no public market for the Common
Stock, and there can be no assurance that a significant public market for the
Common Stock will develop or be sustained after this offering. Future sales of
substantial amounts of Common Stock (including shares issued upon exercise of
outstanding options) in the public market following this offering could
adversely affect market prices of the Common Stock prevailing from time to
time and could impair the Company's ability to raise capital through sale of
its equity securities. As described below, no shares currently outstanding
will be available for sale immediately after this offering because of certain
contractual restrictions on resale. Sales of substantial amounts of Common
Stock of the Company in the public market after the restrictions lapse could
adversely affect the prevailing market price and the ability of the Company to
raise equity capital in the future.     
   
  Upon completion of this offering, the Company will have outstanding an
aggregate of 61,442,498 shares of Common Stock, assuming the issuance of
4,000,000 shares of Common Stock in this offering by the Company. All of the
6,000,000 shares sold in the offering will be freely tradable without
restriction or further registration under the Securities Act, except for any
shares purchased by "affiliates" of the Company as that term is defined in
Rule 144 under the Securities Act. Sales by affiliates will be subject to
certain limitations and restrictions described below.     
          
  As of September 21, 1998, there were a total of 4,319,788 shares of Common
Stock subject to outstanding options granted under the 1997 Equity Incentive
Plan and the 1997 Executive Equity Incentive Plan, 623,146 of which are vested
as of September 21, 1998, and an additional 552,171 of which will become
vested within 180 days of the effective date of this offering. As of September
21, 1998 no shares have been issued under the 1998 Director Option Plan, the
1998 Employee Stock Purchase Plan and the 1998 Stock Plan. The Company intends
to file a registration statement on Form S-8 under the Securities Act to
register shares of Common Stock subject to outstanding stock options or
reserved for issuance under the 1997 Equity Incentive Plan, the 1997 Executive
Equity Incentive Plan, the 1998 Stock Plan, the 1998 Employee Stock Purchase
Plan and the 1998 Director Option Plan (the "Plans") within 180 days after the
date of this Prospectus, thereby permitting the resale of such shares by
nonaffiliates in the public market without restriction under the Securities
Act, subject to restrictions in the lock-up agreements. After the effective
date of the registration statement on Form S-8, shares purchased upon exercise
of options granted or otherwise purchased under the Plans generally would be
available for resale in the public market.     
   
  Holders of 55,442,498 shares of the Company's capital stock and options to
purchase 3,151,468 shares of the Company's capital stock are subject to lock-
up agreements, including all 127 stockholders of the Company and all officers
and directors of the Company. Holders of options to purchase 1,168,320 shares
of the Company's capital stock have not executed lock-up agreements, 60,123 of
which will vest within 180 days of the effective date of this offering. Shares
covered by the lock-up agreements are subject to restrictions on resale in the
public market for a period of 180 days following the effective date of this
offering, subject, in most cases, to release, directly or indirectly, by
Goldman, Sachs & Co. Upon expiration of this lock-up period, 61,442,498 shares
will become eligible for sale in the public market, 53,606,111 of which will
be subject to the volume and other limitations of Rule 144 described below,
51,188,691 of which are held by affiliates of the Company. In addition,
holders of stock options could exercise these options and sell certain of the
shares issued upon exercise as described below.     
   
  Beginning six months after the date of the offering, holders of 52,444,445
shares of Common Stock of the Company also will be entitled to certain rights
with respect to the registration of such shares for sale in the public market.
See "Description of Capital Stock-Registration Rights." Registration of such
shares under the Securities Act would result in such shares becoming freely
    
                                      61
<PAGE>
 
tradable without restriction under the Securities Act (except for shares
purchased by affiliates) immediately upon the effectiveness of such
registration.
   
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least
one year is entitled to sell in "broker's transactions" or to market makers a
number of shares that does not exceed the greater of (i) one percent of the
number of shares of Common Stock then outstanding (approximately 614,425
shares immediately after this offering) or (ii) generally, the average weekly
trading volume in the Common Stock during the four calendar weeks preceding
the required filing of a Form 144 with respect to such sale. Sales under Rule
144 are generally subject to the availability of current public information
about the Company. Under Rule 144(k), a person who is not deemed to have been
an affiliate of the Company at any time during the 90 days preceding a sale,
and who has beneficially owned the shares proposed to be sold for at least two
years (including the holding period of any prior owner except an affiliate),
is entitled to sell such shares without having to comply with the manner of
sale, public information, volume limitation or notice filing provisions of
Rule 144. Under Rule 701 under the Securities Act, persons who purchase shares
upon the exercise of options granted prior to the effective date of this
offering are entitled to sell such shares 90 days after the date of this
Prospectus in reliance on Rule 144, without having to comply with the holding
period and notice filing requirements of Rule 144 and, in the case of non-
affiliates, without having to comply with the public information, volume
limitation or notice filing provisions of Rule 144. However, all such persons
(including all affiliates of the Company) have entered into lock-up agreements
restricting the sale of such shares during the 180-day period following this
offering.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
 
To the Board of Directors and Stockholders of
E-Tek Dynamics, Inc.
 
  In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of stockholders' equity (deficit) and
of cash flows present fairly, in all material respects, the financial position
of E-Tek Dynamics, Inc. and its subsidiaries at June 30, 1997 and 1998 and the
results of their operations and their cash flows for each of the three years
in the period ended June 30, 1998, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of
the Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  THE COMPANY AND DESCRIPTION OF BUSINESS
 
  E-Tek Dynamics, Inc. (the "Company") designs, packages, manufactures and
sells high quality passive components for fiber optic networks.
 
  Until July 23, 1997, the Company was owned by two founders ("the Founders").
In July 1997, the Company underwent a recapitalization in which it sold a
controlling stake in the Company for $120 million in Mandatorily Redeemable
Class A Convertible Preferred Stock ("Convertible Preferred Stock") which has
significant rights and preferences over the Common Stock including rights to
elect a majority of the Company's directors, cumulative dividends and a
liquidation preference. In connection with the recapitalization, the Company
also repurchased $120 million in Common Stock from the Company's Founders. The
redemption was accounted for as a recapitalization and, accordingly, no change
in the accounting basis of the Company's net assets has been made in the
accompanying consolidated financial statements. The amount of cash paid to the
stockholders exceeded the net assets of the Company at the time of the
redemption by $83,901,000. This amount has been recorded in the equity section
as distribution in excess of net book value.
 
  Pursuant to the recapitalization, the Company amended its Articles of
Incorporation to change its authorized number of shares to 90,000,000, of
which 30,000,000 have been designated as Convertible Preferred Stock and
60,000,000 have been designated as Common Stock. Also as of that date, there
was a stock split in which each outstanding share of Common Stock was
converted into 493.72476 shares of Common Stock. All shares and per share
amounts have been restated to reflect the stock split.
 
  On June 18, 1998, the Company amended its Articles of Incorporation again to
increase authorized shares of Common Stock to 65,000,000 shares.
 
  USE OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  PRINCIPLES OF CONSOLIDATION
 
  All intercompany transactions and accounts have been eliminated.
 
  REVENUE RECOGNITION
   
  Revenue from product sales is recognized at the time the product is shipped,
with provisions established for estimated product returns and allowances.     
   
  WARRANTY EXPENSE     
   
  At the time of product shipment, the Company provides for the estimated
costs that may be incurred under warranties for the product shipped.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
  The Company considers all liquid investments purchased with an original
maturity of three months or less to be cash equivalents and those with
original maturities greater than three months to be short-term investments.
 
  The Company's short-term investments at June 30, 1997 consisted of
marketable debt securities (more specifically, municipal bonds and corporate
securities) and mutual funds. The Company has classified all such investments
as available-for-sale. At June 30, 1997, the estimated fair value approximated
the cost of the marketable securities.
 
  INVENTORIES
 
  Inventories are valued at the lower of cost or market, cost being determined
using the first-in, first-out basis.
 
  PROPERTY AND EQUIPMENT
 
  Property and equipment are stated at cost. Depreciation is computed using
the straight-line method based upon the estimated useful lives of the assets,
which is twenty-five years for buildings and range from three to five years
for other property and equipment.
 
  IMPAIRMENT OF LONG-LIVED ASSETS
 
  Pursuant to Statement of Financial Accounting Standards No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-lived Assets to be
Disposed of" ("SFAS 121"), the Company reviews long-lived assets based upon a
gross cash flow basis and will reserve for impairment whenever events or
changes in circumstances indicate the carrying amount of the assets may not be
fully recoverable. Based on its most recent analysis, the Company believes
that there was no impairment of its property and equipment as of June 30,
1998.
 
  RESEARCH AND DEVELOPMENT
 
  Research and development costs are expensed as incurred.
 
  INCOME TAXES
 
  Deferred tax assets and liabilities are recognized for the expected tax
consequences of temporary differences between the tax bases of assets and
liabilities and the amounts reported for financial reporting purposes.
 
  STOCK-BASED COMPENSATION
 
  The Company accounts for its stock-based awards using the intrinsic value
method in accordance with Accounting Principles Board No. 25, "Accounting for
Stock Issued to Employees." The Company provides additional pro forma
disclosures as required under Statement of Financial Accounting Standard No.
123, "Accounting for Stock-Based Compensation" ("SFAS 123").
 
  PRO FORMA BALANCE SHEET (UNAUDITED)
 
  Upon consummation of the Offering, all shares of Convertible Preferred Stock
outstanding will convert into an aggregate of 30,000,000 shares of Common
Stock. The effect of this conversion and the effect of the Company's plan to
reincorporate in Delaware have been reflected in the accompanying unaudited
pro forma consolidated balance sheet as of June 30, 1998.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  RECENTLY ISSUED ACCOUNTING STANDARDS
   
  In June 1997, the Financial Accounting Standards Board issued two new
Statements of Financial Accounting Standards ("SFAS"). SFAS 130, "Reporting
Comprehensive Income," establishes standards for reporting and display of
comprehensive income within a financial statement. This Statement requires the
Company to report additional information on comprehensive income to supplement
the reporting of income. SFAS 130 is effective for fiscal years beginning
after December 15, 1997. Comparative financial statements provided for earlier
periods are required to be reclassified so that comprehensive income is
displayed in a comparative format for all periods presented. SFAS 131,
"Disclosures about Segments of an Enterprise and Related Information,"
establishes standards for reporting information about operating segments in
annual and interim financial statements. This Statement also establishes
standards for related disclosures about products and services, geographic
areas and major customers. SFAS 131 is effective for financial statements for
fiscal years beginning after December 15, 1997. The Company will adopt SFAS
130 for fiscal 1999 and does not expect its provisions to have a material
effect on the Company's presentation of its consolidated financial statements.
The Company will adopt SFAS 131 for fiscal 1999 and is currently studying its
provisions.     
 
  In June 1998, the Financial Accounting Standards Board issued SFAS 133
"Accounting for Derivative Instruments and Hedging Activities." SFAS 133
establishes accounting and reporting standards for derivative instruments and
for hedging activities and is effective for all quarters of fiscal years
beginning after June 15, 1999. The Company does not expect the adoption of
SFAS 133 to have a material impact on the Company's results of operations.

NOTE 3--JOINT VENTURE:
   
  During fiscal 1998, the Company entered into an agreement with a Taiwanese
company to form a joint venture in Taiwan to develop, manufacture and
distribute fiber optic components and products. The Company and the other
investor each contributed $7,000,000 in cash for a 50% interest in the joint
venture. Under the joint venture agreement and a related license agreement,
the Company is to receive $7,000,000 from the joint venture for certain
technology of the Company that was licensed to the joint venture. This amount
was recorded as an advance to the joint venture as of June 30, 1998. The joint
venture agreement does not require the Company to provide any additional
financing to the joint venture.     
 
  The $7,000,000 cash contributed by the Company and the $7,000,000 receivable
from the joint venture offset so that in substance, the Company received a 50%
interest in the joint venture in exchange for a technology license that had no
carrying value in the Company's financial statements. In accordance with
Emerging Issues Task Force Consensus No. 89-7, the Company did not record any
gain on the exchange and, therefore, the carrying value in the Company's
investment in the joint venture as of June 30, 1998 was nil. The joint
venture, which is to supply certain components to the Company, had not
commenced operations as of June 30, 1998.

NOTE 4--BORROWINGS:
 
  COMMERCIAL LINE OF CREDIT
   
  In September 1996, the Company entered into a loan agreement with a
financial institution for a $6,000,000 commercial line of credit. In September
1997, the Company re-negotiated the line, which resulted in an increase in the
line of credit to $15,000,000. This line of credit bears interest at a rate of
LIBOR plus 1.5% per annum (7.3% as of June 30, 1998). This agreement requires
that the Company maintain certain financial ratios, levels of tangible net
worth and profitability. At June 30, 1998, the Company was in compliance with
these requirements. This line of credit is secured by the Company's accounts
receivable, inventories and equipment and expires on December 31, 1998. As of
June 30, 1998, there were no borrowings on this line of credit.

  In November 1996, the Company obtained a $7,700,000 term loan from a
financial institution, which bears interest at a rate of 7.85% per annum.
Monthly principal and interest payments are $59,000, with a final payment of
all remaining unpaid principal and interest on December 1, 2001. This loan is
secured by the Company's land and building.
 
  In September 1997, the Company obtained a $3,000,000 term loan from a bank,
which bears interest at a rate of LIBOR plus 1.7% per annum (7.5% as of June

NOTE 6--MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK:
 
  The holders of the Convertible Preferred Stock have various rights and
preferences as follows:
 
  VOTING
 
  Each share of Convertible Preferred Stock has voting rights equal to an
equivalent number of shares of Common Stock into which it is convertible and
votes together as one class with the Common Stock. Holders of Convertible
Preferred Stock have the right to elect three of the five members of the Board
of Directors.
 
  As long as any shares of the Convertible Preferred Stock remain outstanding,
the Company must obtain approval from a majority of the holders of Convertible
Preferred Stock in order to alter the Articles of Incorporation as related to
the Convertible Preferred Stock, change the authorized number of shares of
Convertible Preferred Stock, repurchase any shares of Common Stock other than
shares subject to the right of repurchase by the Company, change the
authorized number of Directors, authorize a dividend for any class or series
other than the Convertible Preferred Stock, create a new class of stock or
effect a merger, liquidate, dissolve or effect a recapitalization or
reorganization in any form, or sell or transfer more than 25% of the assets of
the Company.
 
  CUMULATIVE DIVIDENDS
 
  Dividends on each share of Convertible Preferred Stock shall accrue at a
rate of 8% per annum of the liquidation value of $4.00 per share. Such
dividends shall accrue whether or not they have been declared and whether or
not there are profits or other funds of the Company legally available for the
payment of dividends, and such dividends shall be cumulative. The accrued and
unpaid dividends should not cause the aggregate stock liquidation value to
exceed $8.00 per share. For the year ended June 30, 1998, the Company recorded
$9,021,000 for the accretion of the value of the Convertible Preferred Stock
related to the 8% dividend per annum on the $120,000,000 liquidation value of
the Convertible Preferred Stock.
 
  The holders of the Convertible Preferred Stock will also be entitled to
participate in dividends on Common Stock, when and if declared by the Board of
Directors, based on the number of shares of Common Stock held on an as-if
converted basis.
 
  The Board of Directors from inception through June 30, 1998 has declared no
other dividends on the capital stock.
 
  LIQUIDATION
 
  In the event of any liquidation, dissolution or winding up of the Company,
the holders of the Convertible Preferred Stock are entitled to receive the
greater of (i) an amount of $4.00 per share, plus any unpaid dividends prior
to and in preference to any distribution to the holders of Common Stock or
(ii) the consideration per share payable to holders of Common Stock assuming
conversion to Common Stock of all outstanding Convertible Preferred Stock,
plus any unpaid dividends prior to liquidation. Should the Company's legally
available assets be insufficient to satisfy the liquidation preferences, the
funds will be distributed pro rata among the holders of the Convertible
Preferred Stock.
 
  REDEMPTION
 
  The holders of the Convertible Preferred Stock have the option to redeem the
stock at the then liquidation value if there is a change in ownership of the
company.

  REGISTRATION RIGHTS
 
  The holders of a majority of Convertible Preferred Stock may demand
registration of all or a portion of their shares. Demand registrations are not
limited in number.
 
  CONVERSION AND ANTIDILUTION PROTECTION
   
  Each share of the Convertible Preferred Stock is convertible into the number
of Common Stock shares computed by multiplying the number of shares to be
converted by $4.00 and dividing the result by the conversion price then in
effect. The conversion price at June 30, 1998 is $4.00, and the basis of
conversion is subject to adjustment on a weighted average basis in the event
of dilution issuance. Each share of Convertible Preferred Stock converts into
the number of shares of Common Stock into which such shares are convertible at
the then effective conversion ratio upon the consent of two-thirds of the
Convertible Preferred Stock holders. Provided that the value of the Common
Stock to be received upon conversion is in excess of $8.00 per share, no
dividends would be paid on Convertible Preferred Stock upon conversion.     
 
  At June 30, 1998, the Company reserved 30,000,000 shares of Common Stock for
the conversion of the Convertible Preferred Stock.
 
NOTE 7--EARNINGS PER SHARE:
 
  Basic net income per share is computed by dividing net income available to
Common Stockholders by the weighted average number of common shares
outstanding during the period. Diluted net income per share is calculated
using the weighted average number of outstanding shares of Common Stock plus
dilutive Common Stock equivalents. For all periods presented, Common Stock
equivalents consist of Convertible Preferred Stock, unvested Common Stock
subject to repurchase and Common Stock options using the treasury stock method
based on the average stock price for the period.

NOTE 8--RESTRICTED STOCK AND STOCK OPTIONS PLANS:
 
  RESTRICTED STOCK
   
  During fiscal 1998, under the Company's stock option plans, the Company
issued 7,211,000 shares of Common Stock to employees and officers of the
Company in exchange for promissory notes in an aggregate principal amount of
$18,215,000. These notes, which are secured by the shares of Common Stock, are
generally payable five years from the purchase date or upon termination from
the Company, whichever comes first. Because these notes receivable do not bear
interest, the $18,215,000 face value was discounted using a six percent
interest rate to $13,615,000, with the difference recorded as deferred
compensation cost. During fiscal 1998, the Company recognized $600,000 of
compensation expense and $600,000 of interest income related to this imputed
interest income. These shares sold in exchange for the promissory notes are
subject to a right of repurchase by the Company, subject to vesting, which is
generally over a four year period from the grant date, until vesting is
complete. At June 30, 1998, there were 5,868,000 shares subject to repurchase.
       
  In addition, under the Company's stock option plans, the Company issued
88,000 shares of Common Stock to employees of the Company for $210,000 in
cash. These shares sold are subject to a right of repurchase by the Company,
subject to vesting, which is generally over a four year period from the date
of grant, until vesting is complete. At June 30, 1998, there were 13,000
shares subject to repurchase.

  1997 EQUITY INCENTIVE PLAN
 
  In July 1997, the Company adopted the 1997 Equity Incentive Plan (the
"Equity Plan") which provides for granting of incentive stock options and non-
statutory stock options to employees, officers and consultants of the Company
for up to 10,556,000 shares of Common Stock.
 
  Under the Equity Plan, incentive stock options are granted at a price that
is not less than 100% of the fair market value of the stock on the date of
grant, as determined by the Board of Directors. Non-statutory stock options
are granted at a price that is not to be less than 85% of the fair market
value of the stock on the date of grant, as determined by the Board of
Directors. The exercise price of any option granted to a 10% stockholder will
not be less than 110% of the fair market value of the stock on the date of
grant, as determined by the Board of Directors.
   
  Options are exercisable immediately subject to repurchase options held by
the Company which generally lapse over a maximum period of four years at such
times and under such conditions as determined by the Board of Directors.     
 
  1997 EXECUTIVE EQUITY INCENTIVE PLAN
 
  In October 1997, the Company adopted the 1997 Executive Equity Incentive
Plan (the "Executive Plan") which provides for granting of incentive stock
options and non-statutory stock options to officers or directors of the
Company for up to 4,444,000 shares of Common Stock.
 
  Under the Executive Plan, incentive stock options are granted at a price
that is not less than 100% of the fair market value of the stock on the date
of grant, as determined by the Board of Directors. Non-statutory stock options
are granted at a price that is not to be less than 85% of the fair market
value of the stock on the date of grant, as determined by the Board of
Directors. The exercise price of any option granted to a 10% stockholder will
not be less than 110% of the fair market value of the stock on the date of
grant, as determined by the Board of Directors.

  The Company calculated the fair value of each option grant on the date of
grant using the minimum value method with the following assumptions: dividend
yield at 0%; weighted average expected option term of five years; risk free
interest rate of 6% for the year ended June 30, 1998. The weighted average
fair value of options granted per share during fiscal 1998 was $0.75.

  Because additional option grants are expected to be made each year, the

reported net income for future years.
   
  RESCISSION OFFER     
   
  From February 4, 1998 to August 14, 1998, the Company issued options to
purchase 3,303,375 shares of its Common Stock to 493 employees of the Company
without complying with certain filing requirements of the California blue sky
laws. As a result, such option grants and the subsequent issuance of Common
Stock upon the exercise of certain of these options were not qualified under
the California state securities laws or otherwise exempt from qualification
under these laws. The Company has recently filed for a permit from the
California Commissioner of Corporations to conduct a rescission offer for the
options and the shares of Common Stock that have been issued pursuant to
certain of these options (the "Rescission Offer"). Pursuant to the Rescission
Offer, the Company will offer to rescind each option grant by repurchasing the
option for 20% of the exercise price of the option (which exercise prices
range from $3.25 to $12.00), plus interest at the statutory rate of seven
percent from the date of grant. In the case of options that have been
exercised, the Company will offer to repurchase the resulting Common Stock for
the full amount of the exercise price, plus seven percent interest from the
date of exercise. If all offerees accept the Rescission Offer, the Company
would be required to make aggregate payments of approximately $6.2 million
plus the aggregate amount of interest as described above. The Company does not
expect to use any portion of the proceeds from the offering to make payments
under the Rescission Offer. Once the Company receives a permit to conduct the
Rescission Offer, the Rescission Offer will commence and remain open until the
earlier of 30 days or such time as all offerees have responded to the
Rescission Offer. After such time, these offerees will no longer have a right
to rescind their options and such options shall be qualified under the
California securities law. There can be no assurance, however, that the
Company will receive a permit to conduct the Rescission Offer, that the
Company will not be required to pay significant amounts to the offerees as a
result of their acceptance of the Rescission Offer, or that the Rescission
Offer will not have a material adverse effect on the Company's business,
financial condition and results of operations.     
 
NOTE 9--EMPLOYEE BENEFIT PLAN:
 
  The Company sponsors a 401(k) Savings Plan (the "Plan"). All employees are
eligible to participate in the Plan following certain minimum eligibility
requirements. Under the Plan, employees may elect to contribute up to 15% of
their pre-tax compensation to the Plan, subject to annual limitations.
Matching employer contributions are 25% of the employees' contributions but
limited to the first 10% of the employees' deferral. Employer contributions
are vested over five years after employees' two years of services and employee
contributions are 100% vested at all times. The Company's contribution to the
plan was $177,000, $211,000 and $313,000 for fiscal 1996, 1997 and 1998,
respectively.

NOTE 10--MAJOR CUSTOMERS AND CONCENTRATION OF RISKS:
 
  Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash equivalents,
investments and trade accounts receivable. The Company invests primarily in
money market accounts and marketable securities and places its investments
with high quality financial, government or corporate institutions. The Company
sell its products to original equipment manufacturers. The Company performs
ongoing credit evaluations of its customers' financial condition and maintains
an allowance for uncollectible accounts receivable based upon the expected
collectibility of all accounts receivable. At June 30, 1997, three customers
accounted for 39%, 13%, and 13% of accounts receivable. At June 30, 1998, two
customers accounted for 43% and 11% of accounts receivable.
 
  During fiscal 1996, three customers accounted for 25%, 16% and 15% of total
revenues. During fiscal 1997, three customers accounted for 27%, 22% and 12%
of total revenues. During fiscal 1998, three customers accounted for 30%, 16%
and 14% of total revenues. The Company has no foreign operations. However,
export sales were approximately 37%, 42% and 53% of total net sales for fiscal
1996, 1997 and 1998, respectively.

</TABLE>    
 
  Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the shares offered
hereby, if any are taken.
   
  The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus, and in part to certain securities dealers at
such price less a concession of $    per share. The Underwriters may allow,
and such dealers may reallow, a concession not in excess of $   per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the offering price and other selling terms may from time
to time be varied by the representatives.     
   
  The Selling Stockholders have granted the Underwriters an option exercisable
for 30 days after the date of this Prospectus to purchase up to an aggregate
of 900,000 additional shares of Common Stock solely to cover over-allotments,
if any. If the Underwriters exercise their over-allotment option, the
Underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof that the number of shares to be
purchased by each of them, as shown in the foregoing table, bears to the
6,000,000 shares of Common Stock offered.     
   
  The Company, the Selling Stockholders, and substantially all of the other
stockholders of the Company have agreed that, during the period beginning from
the date of this Prospectus and continuing to and including the date 180 days
after the date of the Prospectus, not to offer, sell, contract to sell or
otherwise dispose of any shares of Common Stock or any securities of the
Company which are substantially similar to the shares of Common Stock
including but not limited to any securities that are convertible into, or
exchangeable for, or that represent the right to receive Common Stock, or
securities which are substantially similar to the shares of Common Stock,
without the prior written consent of Goldman, Sachs & Co., except that the
Company may issue securities pursuant to employee stock plans and currently
outstanding options.     
 
  The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed five percent of the total number of shares
of Common Stock offered by them.
   
  Prior to this offering, there has been no public market for the shares. The
initial public offering price will be negotiated between the Company, the
Selling Stockholders and the representatives of the Underwriters. Among the
factors to be considered in determining the initial public offering price of
the     
 
                                      U-1
<PAGE>
 
Common Stock, in addition to prevailing market conditions, will be the
Company's historical performance, estimates of the business potential and
earnings prospects of the Company, an assessment of the Company's management
and the consideration of the above factors in relation to market valuation of
companies in related businesses.
   
  In connection with the offering, the Underwriters may purchase and sell the
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover syndicate short positions
created in connection with the offering. Stabilizing transactions consist of
certain bids or purchases for the purpose of preventing or retarding a decline
in the market price of the Common Stock, and syndicate share positions involve
the sale by the Underwriters of a greater number of shares of Common Stock
than they are required to purchase from the Company in this offering. The
Underwriters also may impose a penalty bid, whereby selling concessions
allowed to syndicate members or other broker-dealers in respect of the Common
Stock sold in this offering for their account may be reclaimed by the
syndicate if such securities are repurchased by the syndicate in stabilizing
or covering transactions. These activities may stabilize, maintain or
otherwise affect the market price of the Common Stock, which may be higher
than the price that might otherwise prevail in the open market, and these
activities, if commenced, may be discontinued at any time. These transactions
may be effected on the Nasdaq National Market in the over-the-counter market
or otherwise.     
 
  The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  As permitted by Section 145 of the Delaware General Corporation Law (the
"DGCL"), the Registrant's Certificate of Incorporation provides that each
person who is or was or who had agreed to become a director or officer of the
Registrant or who had agreed at the request of the Registrant's Board of
Directors or an officer of the Registrant to serve as an employee or agent of
the Registrant or as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, shall be
indemnified by the Registrant to the full extent permitted by the DGCL or any
other applicable laws. Such Certificate of Incorporation also provides that
the Registrant may enter into one or more agreements with any person which
provides for indemnification greater or different than that provided in such
Certificate, and that no amendment or repeal of such Certificate shall apply
to or have any effect on the right to indemnification permitted or authorized
thereunder for or with respect to claims asserted before or after such
amendment or repeal arising from acts or omissions occurring in whole or in
part before the effective date of such amendment or repeal.
 
  The Registrant's Bylaws provide that the Registrant shall indemnify to the
full extent authorized by law any person made or threatened to be made a party
to an action or a proceeding, whether criminal, civil, administrative or
investigative, by reason of the fact that he, his testator or intestate was or
is a director, officer or employee of the Registrant or any predecessor of the
Registrant or serves or served any other enterprise as a director, officer or
employee at the request of the Registrant or any predecessor of the
Registrant.
 
  The Registrant has entered into indemnification agreements with its
directors and certain of its officers.
 
  The Registrant intends to purchase and maintain insurance on behalf of any
person who is a director or officer against any loss arising from any claim
asserted against him and incurred by him in any such capacity, subject to
certain exclusions.
 
  See also the undertakings set out in response to Item 17 herein.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
  Since July 1, 1995, the Registrant has sold and issued the following
securities which were not registered under the Security Act of 1933, as
amended (the "Securities Act"):
 
    1. On July 23, 1997, the Registrant issued 30,000,000 shares of its Class
  A Convertible Preferred Stock for an aggregate purchase price of
  $120,000,000, or $4.00 per share, to a group of 8 investors.
 
    2. On July 23, 1997, the Registrant issued 1,111,111 shares of its Common
  Stock for an aggregate purchase price of $2,555,555.30, or $2.30 per share,
  to an executive officer of the Registrant.
 
    3. On July 23, 1997, the Registrant issued 1,111,110 shares of its Common
  Stock for an aggregate purchase price of $2,555,553.00, or $2.30 per share,
  to an employee of the Registrant.
 
    4. From July 1, 1995 to June 30, 1998, the Registrant issued to
  employees, officers, directors and consultants of the Registrant options to
  purchase an aggregate of 10,525,641 shares of Common Stock of the
  Registrant, at exercise prices ranging from $2.30 per share to $10.00 per
  share, pursuant to the Registrant's 1997 Equity Incentive Plan and 1997
  Executive Equity Incentive Plan.
 
    5. From July 1, 1995 to June 30, 1998, the Registrant issued an aggregate
  of 7,299,252 shares of Common Stock of the Registrant upon the exercise of
  options at exercise prices ranging from $2.30 to $10.00 per share.
     
    6. Since June 30, 1998, the Registrant has issued to employees, officers,
  directors and consultants of the Registrant options to purchase
  approximately 1.5 million shares of Common Stock of the Registrant, at an
  exercise price ranging from $10.00 to $12.00 per share, pursuant to the
  Registrant's 1997 Equity Incentive Plan and 1997 Executive Equity Incentive
  Plan.     
     
    7. Since June 30, 1998, the Registrant issued an aggregate of 94,155
  shares of Common Stock of the Registrant upon the exercise of options at
  exercise prices ranging from $2.30 to $10.00 per share.     
   
  The issuances described in paragraphs 1-3 above were deemed to be exempt
from registration under the Securities Act in reliance on Section 4(2) of the
Securities Act as transactions by an issuer not involving a public offering.
In addition, the sale of securities described in Paragraphs 5 and 7 above was
deemed to be exempt from the registration requirements of the Securities Act
in reliance on Rule 701 promulgated under Section 3(b) of the Securities Act
as transactions by an issuer pursuant to compensatory benefit plans and
contracts relating to compensation as provided under such Rule 701. The
recipients of securities in each such transaction represented their intention
to acquire the securities for investment only and not with a view to or for
sale in connection with any distribution thereof and appropriate legends were
affixed to the share certificates and other instruments issued in such
transactions. The granting of stock options described in paragraph 4 and 6
above did not require registration under the Securities Act, or an exemption
therefrom, insofar as such grants did not involve a "sale" of securities as
such term is used in Section 2(3) of the Securities Act. All recipients either
received adequate information about the Registrant or had access, through
employment or other relationships, to information about the Registrant.

ITEM 17. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, 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.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of Prospectus filed as part of
  this Registration Statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, 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.

RE:  REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-1 filed by you with
the Securities and Exchange Commission ("SEC") on August 18, 1998 (Registration
No. 333-61763), as amended by Amendment No. 1 thereto filed with the SEC on
September 22, 1998 (the "Registration Statement"), in connection with the
registration under the Securities Act of 1933, as amended, of up to 6,900,000
shares of your Common Stock, par value .001 (the "Shares"). The Shares include
an over-allotment option granted to the underwriters of the offering to purchase
900,000 shares. We understand that the Shares are to be sold to the underwriters
of the offering for resale to the public as described in the Registration
Statement. As your legal counsel, we have examined the proceedings taken, and
are familiar with the proceedings proposed to be taken, by you in connection
with the sale and issuance of the Shares.

     It is our opinion that, upon completion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, including the proceedings being taken in order to permit such
transaction to be carried out in accordance with applicable state securities
laws, the Shares, when issued and sold in the manner described in the
Registration Statement and in accordance with the resolutions adopted by the
Board of Directors of the Company, will be legally and validly issued, fully
paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendments thereto.

                                    Very truly yours,
