     This summary highlights selected information from this prospectus and does
not contain all of the information that may be important to you. To understand
the risks involved in your investment decision, you should read carefully this
entire prospectus, including the risk factors and our financial statements, and
the documents to which we refer you.

                                   OMM, INC.

     We design, manufacture and sell a family of highly scalable, all-optical,
or photonic, switching subsystems. Our products are based upon our proprietary
implementation of micro-electromechanical systems, or MEMS, which enable all
optical switching of data streams. Our products allow optical network systems
manufacturers to build scalable, cost-effective systems that address next
generation switching needs in the long haul, metropolitan and access segments of
communication networks. As of August 31, 2000 we have sold our products to 19
customers, including, Cisco Systems, Inc., Corvis Corporation, Nortel Networks,
Siemens AG, and Sorrento Networks. In addition, we have entered into strategic
partnerships with Alcatel SA, Siemens AG, Inc. and Sycamore Networks to
collaborate on the development of our next generation of products.

     We design our products to be manufacturable in high volume, and we
continuously optimize our product designs to ensure product quality, reliability
and durability. In addition, we have designed and implemented several
proprietary automated and semi-automated manufacturing systems and processes to
enhance our manufacturing yields and reliably produce higher volumes of products
than generally possible using manual production techniques.

     Communications service providers have invested significant capital in
optical networks to address the increasing demand for high capacity, or high
bandwidth, communications networks, as well as demand for enhanced services and
improved connection times. RHK, a market research and consulting firm, projects
that the global optical networking systems market will increase from $31.5
billion in 1999 to $90.1 billion in 2003.

     As demand for communications services increases, the need to efficiently
move optical data streams onto, around and off of the network is becoming more
acute. Switches, which control optical data stream movement on the network, are
becoming an increasingly critical element of the communications infrastructure.
Optical network switching systems in use today are based on a hybrid technology
that converts optical signals into electrical signals for processing. After
electronic processing, the information must be converted back into an optical
data stream for transmission to its next destination. Switching systems based on
this process are known as optical-electrical-optical, or OEO, systems. These
complex devices are becoming increasingly challenged to support the growth in
optical networks due to a number of limitations, including:

     - an inability to readily support additional signal wavelengths, increases
       in data rates or different transmission protocols as they are added to
       the network;

     - difficulty in changing the configuration of the network or provisioning
       new services; and

     - significant power, cooling and space requirements.

These and other factors can add to costs or limit new revenue opportunities for
communications service providers.

     Our family of photonic switching subsystems enable optical network systems
manufacturers to design and build switching systems that can switch optical data
streams without regard to transmission protocol, data rates or signal
wavelength. Our products enable optical network systems manufacturers to deliver
systems to communications service providers that lower their total cost of
ownership and simplify the process of installing, or provisioning, and modifying
communications services.

     Our objective is to be the leading supplier of highly scalable and reliable
photonic switching subsystems that are integrated into products built by optical
network systems manufacturers. Key elements of our strategy to attain this goal
are to:

     - extend our leadership position in photonic switching technologies;

     - leverage our automation capabilities;

     - broaden our product portfolio;

     - design products for manufacturability;

     - focus exclusively on subsystems; and

     - develop and enhance strategic partnerships with customers.

     We were incorporated in California in June 1997 and reincorporated in
Delaware in March 2000. Our principal offices are located at 9410 Carroll Park
Drive, San Diego, California 92121. Our telephone number is (858) 362-2800, and

                                  RISK FACTORS

     You should carefully consider the following risk factors and all other
information contained in this prospectus before purchasing our common stock.
Investing in our common stock involves a high degree of risk. Risks and
uncertainties, in addition to those we describe below, that are not presently
known to us or that we currently believe are immaterial may also impair our
business operations. If any of the following risks occurs, our business,
operating results and financial condition could be seriously harmed. In
addition, the trading price of our common stock could decline due to the
occurrence of any of these risks, and you may lose all or part of your
investment. See "Note Regarding Forward-Looking Statements."

                         RISKS RELATED TO OUR BUSINESS

WE HAVE NEVER BEEN PROFITABLE, AND WE EXPECT TO CONTINUE TO INCUR NET LOSSES FOR
THE FORESEEABLE FUTURE. IF WE ARE UNABLE TO INCREASE OUR REVENUES, WE MAY NEVER
ACHIEVE PROFITABILITY.

     Since our inception in June 1997, we have incurred significant losses and
expect to continue to incur losses for the foreseeable future. We incurred net
losses of $19.4 million for the six months ended June 30, 2000 and $7.4 million
for the fiscal year ended December 31, 1999. As of June 30, 2000, we had an
accumulated deficit of $28.1 million. To date, we have not achieved
profitability on a quarterly or annual basis.

     Our revenues to date have been limited. We began recognizing revenue on
shipments of our photonic switching subsystems in April 2000, and our customers
are still in the early stages of evaluating, testing and deploying our products.
We have a large amount of fixed expenses and expect to incur significant
manufacturing, research and development, sales and marketing and administrative
expenses in the future. As a result, we will need to generate significantly
higher revenues, while containing manufacturing costs and operating expenses, if
we are ever to achieve profitability. Even if we achieve profitability in the
future, we may not be able to sustain or increase profitability on a quarterly
or annual basis. Due to the lack of cash we generate from operations, we have
funded our operations through the sale of equity securities and equipment lease
financings. If we do not realize sufficient revenue levels to achieve
profitability, we may require additional financing, which may not be available.
If we are unable to attain and sustain profitability, our business could be
severely harmed.

     As a result of our limited operating history, we have only limited data
from operations on which to rely in forecasting future sales, and we also have
limited meaningful historical financial data upon which to plan future operating
expenses. Many of our expenses are fixed, and we may not be able to reduce our
spending if we determine that our revenue will be lower than expected. If we
fail to accurately forecast our revenues and future operating expenses, our
business, financial condition and results of operations could be seriously
harmed.

WE EXPECT THAT OUR REVENUES AND OPERATING RESULTS WILL FLUCTUATE ON A QUARTERLY
AND ANNUAL BASIS, WHICH MAY RESULT IN VOLATILITY IN OUR STOCK PRICE.

     We expect our future quarterly and annual revenues and operating results to
vary significantly from period to period. A number of factors, many of which are
outside of our control, are likely to cause these variations, including:

     - the timing or cancellations of customer orders;

     - shipment scheduling;

     - fluctuations in demand for, and sales of, our products;

     - the ability of our customers to sell their optical networking systems
       that incorporate our products;

     - our ability to significantly expand our internal manufacturing capacity;

     - our ability to improve manufacturing yields and capacity utilization;

                                        5
<PAGE>   11

     - the ability of our suppliers to produce and deliver components to us on a
       timely basis and in the quantity and quality and at the prices that we
       require;

     - competitive factors such as the introduction of new products and product
       enhancements by our competitors, the entry of new competitors into our
       market and pricing pressures;

     - our ability to develop, introduce, manufacture and ship new and enhanced
       products in a timely manner;

     - our ability to control expenses, particularly in light of our limited
       operating history;

     - the loss of one or more of our customers;

     - the potential obsolescence of our inventory;

     - the ability of communication service providers to obtain the necessary
       financing to purchase optical networking systems that incorporate our
       products; and

     - costs related to potential acquisitions of technology or businesses.

     Due to these and other factors, we believe that quarter-to-quarter
comparisons of our operating results will not be meaningful. You should not rely
on our results for any quarter as an indication of our future performance. Our
operating results in future quarters may not meet the expectations of securities
analysts or investors, which would likely cause the price of our common stock to
fall.

WE HAVE LIMITED EXPERIENCE AND UNPROVEN CAPABILITIES IN VOLUME MANUFACTURING. IF
WE ARE UNABLE TO ACHIEVE AND SUSTAIN ADEQUATE VOLUME MANUFACTURING, OUR BUSINESS
WILL SUFFER.

     Our future success depends in large part on our ability to expand and
improve our manufacturing capabilities, and we must devote significant resources
to expanding our manufacturing capabilities and capacities to meet projected
customer and market demand. We have no experience in rapidly increasing our
manufacturing capacity or in manufacturing products at high volumes and have
only recently commenced manufacturing operations. We currently do not rely on
contract manufacturers and have no present intention of using third-party
manufacturers for our products.

     Expanding our manufacturing capacity will be expensive and will require
significant management attention. There are a number of factors which will
affect our ability to increase manufacturing capacity, including:

     - our ability to procure and install the necessary manufacturing equipment;

     - our ability to achieve adequate yields from existing or new manufacturing
       lines;

     - our ability to recruit, train and retain qualified manufacturing
       personnel;

     - the availability of suitable manufacturing facilities;

     - our ability to implement quality control systems and achieve any required
       quality certifications;

     - our ability to schedule production to meet customer demand; and

     - our ability to improve and develop automated manufacturing capabilities.

     Any of these factors could impair our ability to fulfill orders, which
could result in the loss of our customers. The loss of our customers or any
decrease in sales to our customers could seriously harm our business.

AS WE EXPAND OUR MANUFACTURING CAPACITY, WE MUST ACHIEVE AND MAINTAIN ACCEPTABLE
MANUFACTURING YIELDS OR OUR CUSTOMER SHIPMENTS MAY BE DELAYED, WHICH WOULD
NEGATIVELY IMPACT OUR REVENUES AND CAUSE US TO INCUR ADDITIONAL COSTS.

     We have only recently begun commercial production of our products, which
involves complex and precise manufacturing processes. It is critical to our
ability to grow that we achieve and maintain acceptable manufacturing yields on
our current family of products. In addition, we must develop the ability to
continuously transfer production from product development levels to volume
manufacturing and attain and maintain acceptable yields for each new product or
product enhancement that we introduce. If we fail
                                        6
<PAGE>   12

to achieve and maintain acceptable yields on our current products and future
products or product enhancements, our ability to deliver products to customers
in a timely manner and in the quantities that they require would be
significantly impaired.

WE CURRENTLY DERIVE ALL OF OUR REVENUES FROM A SINGLE PRODUCT FAMILY, AND IF
THIS PRODUCT FAMILY DOES NOT ACHIEVE COMMERCIAL SUCCESS, OUR BUSINESS AND
RESULTS OF OPERATIONS WILL BE HARMED.

     We currently derive all of our revenues from a single family of photonic
switching subsystems, and we expect that this product family will continue to
account for a substantial portion of our total revenues for the foreseeable
future. Market acceptance of our product family by optical network systems
manufacturers will be critical to our future success and growth. To date, our
customers have purchased our photonic switching subsystems for evaluation,
testing and early deployment, however, our products have not been broadly
deployed in commercially available switching systems. If our target customers do
not integrate our products into their optical switching systems or if these
systems do not in turn gain acceptance among communication service providers,
our revenues will not grow and our business, financial condition and results of
operations will be seriously harmed.

     If we are unable to expand our manufacturing capacity in a timely manner,
or if we do not accurately project demand, we could have excess capacity or
insufficient capacity, either of which could seriously harm our business.

     We are currently expanding our manufacturing capabilities and making
capital expenditures based on anticipated levels of customer orders that may not
be realized. Even if we receive orders in one period, demand may not be
sustained over multiple quarters, and the manufacturing capacity that we have
added may be underutilized in subsequent quarters. If anticipated levels of
customer orders are not received, our gross margins will decline, and we may not
be able to reduce our operating expenses quickly enough to prevent a decline in
our operating results.

WE MUST ACHIEVE DESIGN WINS WITH POTENTIAL CUSTOMERS, OR WE MAY LOSE THE
OPPORTUNITY FOR SIGNIFICANT SALES TO THESE CUSTOMERS FOR A LENGTHY PERIOD OF
TIME.

     Once an optical network systems manufacturer decides to use a particular
supplier's component or subsystem, that manufacturer will design the component
or subsystem into its system, which is known as a design win. Suppliers whose
components or subsystems are designed into the manufacturer's system will,
generally, continue to make sales to that manufacturer until the system is
redesigned or discontinued. Even then, the manufacturer may be reluctant to
design entirely new products into its new systems, as doing so could involve
significant and costly additional redesign efforts. As a result, if we are
unable to secure a design win in a potential customer's particular system, we
may be unable to sell our products to that customer for a lengthy period of
time. If we are unable to secure a sufficient number of design wins, our ability
to grow our business would be significantly impaired.

OUR PRODUCTS' SALES CYCLES ARE LONG, WHICH COULD RESULT IN FLUCTUATIONS IN
REVENUES AND OPERATING RESULTS FROM QUARTER TO QUARTER.

     We have only recently begun selling our products and, as a result, our
experience with the sales cycle for our products is limited. Customers often
view the purchase of our products as a significant and strategic decision. As a
result, customers may expend significant effort in evaluating, testing and
qualifying our products and manufacturing processes. This customer evaluation
and qualification process can result in a lengthy initial sales cycle of several
months or more. Before customers place an order with us, we may incur
substantial sales and marketing and research and development expenses to
customize our products to our customers' needs. We may also devote significant
management attention, increase manufacturing capacity and order long-lead-time
components or materials prior to receiving an order. Even after this evaluation
process, a potential customer may not purchase any of our products. Because of
the evolving nature of our business, we have only limited experience in
predicting the length of these sales cycles; however, we expect these sales
cycles to remain lengthy for the foreseeable future. As a result, our long

                                        7
<PAGE>   13

sales cycles may cause our revenues and operating results to vary significantly
and unexpectedly from quarter to quarter which could harm our results of
operations.

WE DEPEND ON LIMITED- OR SOLE-SOURCE SUPPLIERS FOR SOME OF THE KEY COMPONENTS
AND MATERIALS USED TO BUILD OUR PRODUCT, WHICH MAKES US SUSCEPTIBLE TO SUPPLY
SHORTAGES, PRICE FLUCTUATIONS, OR VARYING LEAD TIMES, ANY OF WHICH COULD
ADVERSELY AFFECT OUR OPERATING RESULTS.

     We currently purchase, and expect to continue purchasing, several key
components and materials used in the manufacture of our product from limited- or
sole-source suppliers. We typically purchase our components and materials
through purchase orders and have no guaranteed supply arrangement with many of
our suppliers. We may fail to obtain these supplies in a timely manner in the
future. We may also experience difficulty identifying and evaluating alternative
sources of supply for certain components used in our product. Furthermore,
financial or other difficulties that these suppliers may face or consolidation
among our suppliers could limit the availability of our supplies. In addition,
lead times for components and materials vary significantly and depend on
numerous factors, including the specific supplier, the size of the order,
contract terms and current market demand for such components. For substantial
increases in production levels, some suppliers may require long lead-times. If
we over- or underestimate our component and material requirements, we may
negatively impact our inventory expense or manufacturing capability. Any changes
in the quantity of components or materials we demand, interruption or delay in
the supply of any of these components or materials, or an inability to obtain
these components and materials from alternate sources at acceptable prices and
within a reasonable amount of time, would impair our ability to meet scheduled
product deliveries to our customers and could cause customers to cancel orders
and seek supply from competitors, which would harm our business.

WE GENERATE OUR REVENUES FROM A LIMITED NUMBER OF CUSTOMERS. ANY DECREASE IN
REVENUES FROM, OR LOSS OF, THESE CUSTOMERS WOULD HARM OUR OPERATING RESULTS.

     Our customer base is limited and highly concentrated. Four customers
accounted for approximately 76% of our revenues for the six months ended June
30, 2000. We also expect that the majority of our revenues will continue to be
generated from sales of our products to a limited number of customers. If one or
more of these customers were to decrease its order levels or stop ordering from
us altogether, our results of operations could suffer. Customers in our industry
tend to order products on an irregular basis. None of our current customers has
any minimum purchase obligations, and each may stop placing orders with us at
any time. These ordering patterns may result in significant quarterly
fluctuations in our revenues and operating results. In addition, any downturn in
the business of our existing customers could result in significantly decreased
sales to these customers, which could seriously harm our revenues and results of
operations.

OUR PRODUCTS MAY CONTAIN DEFECTS THAT ARE NOT DETECTED UNTIL AFTER OUR PRODUCTS
HAVE BEEN INSTALLED IN OUR CUSTOMERS' SYSTEMS. THESE DEFECTS MAY CAUSE US TO
INCUR SUBSTANTIAL COSTS AND SUFFER DAMAGE TO OUR REPUTATION.

     Our products are designed to be deployed in large and complex optical
network systems and must be compatible with other components of the optical
network system. Because of the nature of our products, they can only be fully
tested for reliability when deployed in networks carrying live traffic for long
periods of time. Our customers have purchased our photonic switching subsystems
for evaluation, testing and early deployment and have not yet fully deployed our
products in large network environments. Accordingly, they may discover defects
in our products after they have been fully deployed and tested under peak stress
conditions. In addition, our products are combined with products from other
vendors. As a result, should problems occur, it may be difficult to identify the
source of the problem. If we are unable to fix defects or other problems that
may be identified in full deployment, we could experience a:

     - loss of, or delay in, revenue and loss of market share;

     - loss of existing customers;

                                        8
<PAGE>   14

     - failure to attract new customers or for our products to achieve market
       acceptance;

     - diversion of research and development resources;

     - increased service and warranty costs;

     - increased product development expense;

     - damage to our reputation;

     - diversion of management's attention;

     - legal actions by our customers; and

     - increased insurance costs.

     In addition, we may be subject to product return, warranty and product
liability claims resulting from defects in our products which could result in
financial liability to us and the loss of our customers.

WE MUST MANAGE OUR GROWTH EFFECTIVELY, OR OUR RESULTS OF OPERATIONS MAY SUFFER.

     We were incorporated in June 1997 and began operations shortly thereafter.
Until April 2000, our operations were primarily limited to research and
development efforts for our products. We continue to expand the scope of our
operations and have substantially increased the number of our employees in the
past year. At December 31, 1999, we had approximately 55 employees, and at
August 31, 2000, we had over 200 employees. We are planning to rapidly expand
our manufacturing and development capabilities.

     The growth in employee headcount, combined with the challenges of managing
the expansion of our manufacturing operations, has placed, and our anticipated
growth in future operations will continue to place, a significant strain on our
management systems and resources. We expect that we will need to continue to
improve our financial and managerial controls, reporting systems and procedures
and continue to expand, train and manage our work force. If we are unable to
implement on a timely basis the necessary controls and policies to manage our
growth, our operating results could suffer.

WE MUST DEVELOP AND SUCCESSFULLY INTRODUCE NEW AND ENHANCED PRODUCTS THAT MEET
THE NEEDS OF OUR CUSTOMERS OR OUR FUTURE SUCCESS AND RESULTS OF OPERATIONS COULD
BE SIGNIFICANTLY HARMED.

     Our future success depends on our ability to develop and manufacture
products that address our customers' needs. We anticipate that we will need to
manufacture products in volume that offer enhanced capabilities such as the
ability to support a higher number of fiber connections, or ports. To introduce
new products and product enhancements, we will be required to successfully
develop and effectively transfer production processes from the research and
development phase to volume manufacturing and coordinate our efforts with those
of our suppliers to meet customer and market requirements. Developing products
and product enhancements such as ours is difficult, costly and time consuming.
If we fail to develop product enhancements or introduce new products that meet
the needs of our customers, or fail to effectively transfer production
processes, our customers may no longer choose to purchase our existing or future
products which would cause our revenues to decline. Even if we are able to
develop and commercially introduce new products and enhancements, we cannot
assure you that our new products or enhancements will achieve market acceptance,
which could significantly harm our future success and results of operations.

WE MUST MANUFACTURE PRODUCTS THAT MEET INDUSTRY QUALITY STANDARDS, OR OUR
CUSTOMERS MAY CHOOSE NOT TO PURCHASE OUR PRODUCTS, WHICH WOULD HARM OUR
OPERATING RESULTS.

     Our existing manufacturing line, as well as each new manufacturing line,
must pass through varying levels of qualification by our customers. Generally,
customers do not purchase our products, other than limited numbers of evaluation
units, prior to qualification of our manufacturing line for volume production
and approval of our quality control systems. Customers may require that we be
certified under international quality standards such as ISO 9001 or other
industry standards such as those specified by
                                        9
<PAGE>   15

Telcordia or the Network Equipment Building Standards, or NEBS, requirements.
Our products may also have to meet specific customer requirements. Our
manufacturing line has not yet been qualified for volume production by any of
our customers, and we have not yet completed certification under the ISO 9001
quality standard or any other industry standards. If we experience delays in
receiving customer qualifications or ISO 9001 certification, our customers may
choose not to purchase products from us, which would result in significant lost
revenue opportunities that would harm our business.

WE DEPEND ON SEVERAL KEY PERSONNEL TO MANAGE OUR BUSINESS EFFECTIVELY IN A
RAPIDLY CHANGING MARKET.

     Our future success depends upon the continued services of our executive
officers and other key engineering, sales, marketing, manufacturing and support
personnel. None of our officers or key employees is bound by an employment
agreement for any specific term, and these persons may terminate their
employment at any time. In addition, we do not have "key person" life insurance
policies covering any of our employees. The loss of the services of any of our
key employees could delay the development and production of our products and
negatively impact our ability to maintain customer relationships, which could
harm our business, financial condition and results of operations. In addition,
many of the members of our management team have only been with us for a
relatively short period of time. Failure of the management team to work
effectively together could seriously harm our business.

WE MAY BECOME INVOLVED IN COSTLY AND TIME-CONSUMING LITIGATION THAT MAY
SUBSTANTIALLY INCREASE OUR COSTS AND THEREBY HARM OUR BUSINESS.

     We may from time to time become involved in various lawsuits and legal
proceedings which arise in the ordinary course of our business. Any litigation
to which we are a party could require significant involvement of our senior
management and may divert management's attention from our business and
operations. An adverse result in any litigation that may arise from time to time
may adversely impact our operating results or financial condition.

WE MAY NOT BE ABLE TO PROTECT OUR PROPRIETARY TECHNOLOGY. THE LOSS OF OUR
PROPRIETARY TECHNOLOGY COULD ADVERSELY AFFECT OUR ABILITY TO COMPETE.

     We rely on a combination of patent, copyright, trademark, trade secret laws
and restrictions on disclosure to protect our intellectual property rights. To
date, we have filed five U.S. patent applications and three foreign patent
applications. However, we cannot assure you that our patent applications will be
approved, that any patents that may issue will protect our intellectual property
or that any issued patents will not be challenged by third parties. Other
parties may independently develop similar or competing technologies or design
around any patents that may be issued to us. In addition, we have received
limited product development funding from U.S. governmental agencies. We cannot
assure you that the U.S. government will not attempt to assert intellectual
property rights pursuant to our agreements with these agencies. We also enter
into confidentiality or license agreements with our employees, consultants and
corporate partners and control access to and distribution of our confidential
information and proprietary technology. We cannot be certain that the steps we
have taken will prevent the misappropriation of our intellectual property,
particularly in foreign countries where the laws may not protect our proprietary
rights as fully as in the United States.

WE COULD BECOME SUBJECT TO LITIGATION REGARDING INTELLECTUAL PROPERTY RIGHTS,
WHICH COULD DIVERT MANAGEMENT ATTENTION, CAUSE US TO INCUR SIGNIFICANT COSTS AND
PREVENT US FROM SELLING OR USING THE CHALLENGED TECHNOLOGY.

     In recent years, there has been significant litigation in the United States
involving patents and other intellectual property rights. Although we are not
currently party to any litigation, in the future, we may be a party to
litigation to protect our intellectual property or as a result of an alleged
infringement of others' intellectual property. These claims and any resulting
lawsuit, if successful, could subject us to significant liability for damages
and invalidation of our proprietary rights. These lawsuits, regardless of their
success, would likely be time-consuming and expensive to resolve and would
divert management time and
                                       10
<PAGE>   16

attention. Any potential intellectual property litigation also could force us to
do one or more of the following:

     - stop selling, incorporating or using our products that use the challenged
       intellectual property;

     - obtain from the owner of the infringed intellectual property right a
       license to sell or use the relevant technology, which license may not be
       available on reasonable terms, or at all; or

     - redesign the products that use the technology.

     If we are forced to take any of these actions, our business may be
seriously harmed.

     We may in the future initiate claims or litigation against third parties
for infringement of our proprietary rights to protect these rights or to
determine the scope and validity of our proprietary rights or the proprietary
rights of competitors. These claims could result in costly litigation and the
diversion of our technical and management personnel.

WE MAY ATTEMPT TO MAKE ACQUISITIONS WHICH COULD DISRUPT OUR BUSINESS AND HARM
OUR FINANCIAL CONDITION.

     We may make strategic acquisitions of complementary companies, products or
technologies. In the event of any future acquisitions, we could:

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

     - incur debt;

     - assume liabilities; or

     - incur expenses related to in-process research and development,
       amortization of goodwill and other intangible assets.

These purchases also involve numerous risks, including:

     - problems integrating the acquired operations, technologies or products
       into our business;

     - unanticipated costs or liabilities;

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

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

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

     - potential loss of key employees, particularly those of the purchased
       organizations.

     We cannot assure you that we will be able to successfully integrate any
businesses, products, technologies or personnel that we might acquire in the
future, which may harm our business.

OUR FACILITIES COULD EXPERIENCE CATASTROPHIC LOSS, WHICH WOULD SERIOUSLY HARM
OUR OPERATIONS.

     Our facilities could be subject to a catastrophic loss such as fire, flood
or earthquake. All of our research and development activities, manufacturing,
corporate headquarters and other critical business operations are located near
major earthquake faults in San Diego, California. Any loss at any of our
facilities could disrupt our operations, delay production, shipments and revenue
and result in large expense to repair and replace our facilities. While we have
obtained insurance to cover most potential losses at our facilities, we cannot
assure you that our existing insurance coverage will be adequate against all
possible losses or interruption of manufacturing activities.

                         RISKS RELATED TO OUR INDUSTRY

THE OPTICAL NETWORKING INDUSTRY MUST WIDELY ADOPT OUR ALL-OPTICAL SWITCHING
TECHNOLOGIES, OR OUR BUSINESS WILL SUFFER.

     The predominant technology for switching optical signals today is based on
optical-electrical-optical, or OEO, conversions. OEO switches convert optical
signals to electrical signals before switching the signals and converting them
back to optical signals for further transmission. Our success depends on the
willingness of optical network systems manufacturers to embrace all-optical
switching technologies such as those that we make that do not require the
conversion of light to electricity. The all-optical switching market is new, and
we cannot assure you that optical network systems manufacturers will choose to
build products based on all-optical switching technologies. In addition, a
number of alternative all-optical technologies are being developed that may be
directly competitive to ours. Our future success depends on our customers
rapidly adopting all-optical switching generally and the micro-electromechanical
systems, or MEMS-based technology on which our products are based.

THE OPTICAL NETWORKING INDUSTRY IS SUBJECT TO RAPID TECHNOLOGICAL CHANGE. IF WE
CANNOT KEEP PACE WITH THIS TECHNOLOGICAL CHANGE, OUR BUSINESS WILL SUFFER.

     The optical networking industry is characterized by rapid technological
change, frequent new product introductions, changes in customer requirements and
evolving industry standards. In developing our products, we have made, and will
continue to make, assumptions with respect to which standards will be adopted
within our industry. If the standards that are actually adopted are different
from those that we have chosen to support, our products may not achieve
significant market acceptance and our business will suffer.

WE FACE SIGNIFICANT COMPETITION WHICH COULD HARM OUR BUSINESS AND RESULTS OF
OPERATIONS.

     We face competition from a number of large, established public companies,
such as Agilent Technologies, Inc., Corning Incorporated, JDS Uniphase
Corporation, Lucent Technologies Inc.'s Microelectronics Division and Nortel
Networks, Inc., that offer a wide range of components and subsystems to optical
network systems manufacturers. In addition, a number of private companies have
announced plans for all-optical switching products to address many of the same
applications that our products address. We also compete with several companies,
such as PMC-Sierra, Inc. and Applied Micro Circuits Corporation, that provide
optical-electrical-optical, or OEO based switching products to optical network
systems manufacturers. Moreover, some of our customers may develop all-optical
switching subsystems that compete with our products.

     Many of our current and potential competitors have longer operating
histories and significantly greater financial, technical, marketing and other
resources than we have. As a result, these competitors are able to devote
greater resources than we can to the development, promotion, sale and support of
their products. In addition, several of our competitors have large market
capitalizations or cash reserves than we do and may be much better positioned
than we are to acquire other companies in order to gain access to new
technologies or products that may displace our products. In addition, many of
our competitors have much greater name recognition, more extensive customer
bases, better-developed distribution channels and broader product offerings than
we have. These companies can leverage their customer bases and broader product
offerings and adopt aggressive pricing policies to gain market share, all of
which could harm our business.

     Additional competitors may enter the market, and we are likely to compete
with new companies in the future. We expect to encounter potential customers
that, due to existing relationships with our competitors, are committed to the
products offered by these competitors. As a result of the above-mentioned
factors, we expect that competitive pressures may result in price reductions,
reduced margins and loss of market share, all of which could harm our business.

                                       12
<PAGE>   18

IF WE CANNOT RECRUIT AND HIRE ADDITIONAL QUALIFIED PERSONNEL, OUR BUSINESS AND
RESULTS OF OPERATIONS COULD BE HARMED.

     We must hire a significant number of additional employees in the next 12
months, particularly engineering and manufacturing personnel. Competition for
highly skilled personnel is intense. Our ability to continue to attract and
retain highly skilled personnel will be a critical factor in determining whether
we will be successful in the future. We may not be successful in attracting,
training or retaining qualified personnel to fulfill our current or future
needs, which would harm our business.

WE MAY NEED TO OBTAIN LICENSES OF THIRD-PARTY TECHNOLOGY THAT MAY NOT BE
AVAILABLE TO US OR MAY BE VERY EXPENSIVE AND MAY PREVENT US FROM OPERATING OUR
BUSINESS.

     From time to time we may be required to license technology from third
parties to develop new products or product enhancements. We cannot assure you
that third-party licenses will be available to us on commercially reasonable
terms, if at all. Our inability to obtain any third-party license required to
develop new products and product enhancements could require us to obtain
substitute technology of lower quality or performance standards or at greater
cost, any of which could seriously harm our business, financial condition and
results of operations.

OUR MANUFACTURING PROCESSES INVOLVE THE USE OF SOME HAZARDOUS MATERIALS.
ENVIRONMENTAL LAWS AND REGULATIONS MAY EXPOSE US TO LIABILITY AND INCREASE OUR
COSTS.

     We handle hazardous materials as part of our manufacturing activities.
Consequently, our operations are subject to environmental laws and regulations
governing, among other things, the use and handling of hazardous substances and
waste disposal. We may be required to incur environmental costs to comply with
current or future environmental laws. As with other companies engaged in
manufacturing activities that involve hazardous materials, a risk of
environmental liability is inherent in our manufacturing activities. The costs
associated with environmental compliance or remediation efforts or other
environmental liabilities could adversely affect our business.

                         RISKS RELATED TO THIS OFFERING

WE MAY BE REQUIRED TO RAISE ADDITIONAL CAPITAL. IF ADDITIONAL CAPITAL IS NOT
AVAILABLE TO US ON REASONABLE TERMS, OUR ABILITY TO GROW MAY BE LIMITED.

     The development and marketing of new products as well as the expansion of
our manufacturing facilities, and adding support and sales and marketing
personnel will require a significant commitment of resources. As a result, we
may be required, or could elect, to seek additional funding. In addition, if the
market for our product develops at a slower pace than anticipated, or if we fail
to establish market share and increase revenues, we may continue to incur
significant operating losses and utilize significant amounts of capital. If our
current capital resources are insufficient to support our operating losses, or
if we utilize our capital resources for acquisitions or other unanticipated
uses, we may need additional capital. In the event we are required to raise
additional funds, we may not be able to do so on favorable terms, or at all.
Further, if we issue new equity securities, stockholders will experience
additional dilution or the new equity securities may have rights, preferences or
privileges senior to those of existing holders of common stock. If we cannot
raise funds on acceptable terms, we may not be able to develop or enhance our
products, take advantage of future opportunities or respond to competitive
pressures or unanticipated requirements. Our inability to raise additional
capital when we require it would seriously harm our business.

WE EXPECT TO EXPERIENCE VOLATILITY IN OUR SHARE PRICE, WHICH COULD NEGATIVELY
AFFECT YOUR INVESTMENT. YOU MAY NOT BE ABLE TO RESELL YOUR SHARES AT OR ABOVE
THE INITIAL PUBLIC OFFERING PRICE.

     This initial public offering price is likely to vary significantly from the
market price of our common stock after the offering. If you purchase shares of
common stock, you may not be able to resell those

                                       13
<PAGE>   19

shares at or above the initial public offering price. The market price of our
common stock may fluctuate significantly in response to a number of factors,
some of which are beyond our control, including:

     - quarterly variations in our operating results;

     - changes in financial estimates by securities analysts;

     - changes in market valuations of other optical networking component and
       systems manufacturers, or technology companies generally;

     - announcements by us, our competitors or other parties relating to new
       products, significant technical innovations, contracts, acquisitions or
       strategic partnerships;

     - rumors in the marketplace;

     - any loss of a major customer;

     - additions or departures of key personnel;

     - changes in general economic outlooks and stock market volatility;

     - any deviations in revenues or in losses from the levels expected by
       securities analysts; and

     - future sales of common stock.

     In addition, the stock market has experienced extreme volatility that has
often been unrelated to the performance of particular companies. These market
fluctuations may cause our stock price to fall regardless of our performance.

THERE MAY BE SALES OF A SUBSTANTIAL AMOUNT OF OUR COMMON STOCK AFTER THIS
OFFERING THAT COULD CAUSE OUR STOCK PRICE TO FALL.

     Our current stockholders hold a substantial number of shares, which they
will be able to sell in the public market in the near future. Sales of a
substantial number of shares of our common stock after this offering could cause
our stock price to fall. In addition, the sale of these shares could impair our
ability to raise capital through the sale of additional stock.

     Based upon shares outstanding as of August 31, 2000, upon completion of
this offering, we will have outstanding                shares of common stock.
Our stockholders will be subject to lock-up agreements with the underwriters or
us that restrict their ability to transfer their stock for 180 days from the
date of this prospectus, as described in "Underwriting". Assuming that this
prospectus will be dated                     , 2000, these lock-up agreements
will expire on                , 2001, and an aggregate of                shares
will be eligible for sale, in some cases subject only to the volume, manner of
sale and notice requirements of Rule 144 under the Securities Act.
Notwithstanding the 180-day lock-up period, 25% of the shares, or
               shares, subject to these lock-up restrictions, including
               shares held by our executive officers and directors, may be
released from these restrictions beginning 90 days from the date of this
prospectus, or             , 2001. This release will occur if the last reported
sale price of our common stock is at least two times the initial public offering
price per share for 20 of the 30 trading days preceding the 90th day after the
date of this prospectus. Of these shares to be released on                ,
2000,                will be eligible for sale, in some cases subject only to
the volume, manner of sale and notice requirements of Rule 144.

MANAGEMENT MAY APPLY THE PROCEEDS OF THIS OFFERING TO USES THAT DO NOT INCREASE
OUR PROFITS OR MARKET VALUE, WHICH MAY CAUSE THE VALUE OF YOUR INVESTMENT TO
DECLINE.

     Our management will have considerable discretion in the application of the
net proceeds of this offering, and you will not have the opportunity, as part of
your investment decision, to assess whether the proceeds are being used
appropriately. The net proceeds may be used for corporate purposes that do not
increase our profitability or our market value. Pending application of the
proceeds, they may be placed in investments that do not produce income or that
lose value.

THERE HAS BEEN NO PRIOR MARKET FOR OUR COMMON STOCK. AN ACTIVE PUBLIC MARKET FOR
OUR SECURITIES MAY NOT DEVELOP OR BE SUSTAINED, WHICH COULD MAKE IT MORE
DIFFICULT FOR YOU TO SELL YOUR STOCK.

     Prior to this offering, there was no public market for our common stock. An
active public market for our common stock may not develop or be sustained after
this offering, and the market price for our stock might fall below the initial
public offering price. The initial public offering price may bear no
relationship to the price at which the common stock will trade in the open
market after this offering. The initial public offering price will be determined
based on negotiations between us and the representatives of the underwriters,
based on factors that may not be indicative of future market performance.

INSIDERS WILL CONTINUE TO HAVE SUBSTANTIAL CONTROL OVER OMM AFTER THIS OFFERING,
WHICH COULD DELAY OR PREVENT A CHANGE IN OUR CORPORATE CONTROL.

     Upon completion of this offering, our executive officers, directors and
principal stockholders who hold 5% or more of the outstanding common stock and
their affiliates will beneficially own, in the aggregate, approximately      %
of our outstanding common stock. As a result, these stockholders will be able to
exercise significant control over all matters requiring stockholder approval,
including the election of directors and approval of mergers or significant
corporate transactions, which could delay or prevent an outside party from
acquiring or merging with us. The ability of insiders to prevent or delay these
transactions could cause the price of our common stock to decline.

INVESTORS WILL EXPERIENCE IMMEDIATE DILUTION AS A RESULT OF THIS OFFERING.

     The initial public offering price of our common stock is expected to be
substantially higher than the book value per share of our outstanding common
stock immediately after the offering. Accordingly, if you purchase our common
stock in this offering, you will incur immediate dilution of approximately
$          in the book value per share of our common stock from the price you
pay for our common stock. This calculation assumes that you purchased our common
stock for $     per share.

PROVISIONS OF OUR CHARTER DOCUMENTS, DELAWARE LAW AND CHANGE OF CONTROL
AGREEMENTS THAT WE HAVE ENTERED INTO MAY HAVE ANTI-TAKEOVER EFFECTS THAT COULD
HINDER A CHANGE IN OUR CORPORATE CONTROL.

     Provisions of our certificate of incorporation and bylaws may discourage,
delay or prevent a merger or acquisition that a stockholder may consider
favorable. These provisions include:

     - authorizing our board of directors to issue preferred stock without
       stockholder approval;

     - providing for a classified board of directors with staggered, three-year
       terms;

     - eliminating the ability of stockholders to call special meetings; and

     - prohibiting stockholder actions by written consent.

     Certain provisions of Delaware law also may discourage, delay or prevent
someone from acquiring or merging with us, which may cause the market price of
our common stock to decline. In addition, we have change of control agreements
with each of our officers, which may discourage, delay or prevent someone from
acquiring or merging with us.

                   NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Some of the information in this prospectus contains forward-looking
statements that involve substantial risks and uncertainties. You can identify
these statements by forward-looking words such as "may," "will," "expect,"
"anticipate," "believe," "estimate," "plan" and "continue" or similar words. You
should read statements that contain these words carefully because they: (1)
discuss our future expectations; (2) contain projections of our future results
of operations or of our financial condition; or (3) state other
"forward-looking" information. We believe that it is important to communicate
our future expectations to our investors. However, there may be events in the
future that we have not accurately predicted or which we cannot control. These
events may include our future operating results, our ability to implement our
business plan and potential competition, among other things. The risk factors
listed under "Risk Factors," as well as any cautionary language in this
prospectus, provide examples of risks, uncertainties and events that may cause
our actual results to differ materially from the expectations we describe in our
forward-looking statements.

     Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements. Moreover, neither we nor any other person
assumes responsibility for the accuracy and completeness of these statements. We
are under no duty to update any of the forward-looking statements after the date
of this prospectus to conform these statements to actual results.

                                USE OF PROCEEDS

     We expect to receive net proceeds of approximately                from the
sale of the                shares of common stock, or approximately
               if the underwriters exercise their over-allotment option in full,
at an assumed initial public offering price of $     per share, after deducting
the underwriting discounts and commissions and estimated offering expenses
payable by us.

     We intend to use the net proceeds from this offering to expand our
manufacturing capabilities and research and development efforts, as well as for
working capital and general corporate purposes. In addition, we may use a
portion of the net proceeds to acquire businesses, products or technologies that
are complimentary to our current or future business and product lines. We are
not currently negotiating any acquisitions, and we have no agreements with any
third party for any acquisitions. Pending use of the net proceeds of this
offering, we intend to invest the net proceeds in interest-bearing,
investment-grade securities.

                                DIVIDEND POLICY

     We have never declared or paid any cash dividends on our capital stock. We
currently expect to retain future earnings, if any, for use in the operation and
expansion of our business and do not anticipate paying any cash dividends in the
foreseeable future. Some of our lease lines and credit agreements prohibit the
payment of dividends without the creditor's prior approval.

                                 CAPITALIZATION

     The following table sets forth our capitalization as of June 30, 2000:

     - on an actual basis:

     - on a pro forma basis after giving effect to:

       --  the automatic conversion of each outstanding share of our preferred
           stock into three shares of our common stock; and

       --  the issuance of 83,901 shares of our common stock upon the exercise
           of outstanding warrants that, if not exercised by the holders, will
           expire upon the closing of this offering at a weighted average
           exercise price of $0.24 per share.

     - on a pro forma as adjusted basis after giving effect to the sale of
                      shares of common stock at an assumed initial public
       offering price of $     per share, less the underwriting discounts and
       commissions and estimated offering expenses payable by us, and the
       application of the net proceeds

     You should read this table in conjunction with our financial statements and

     - 13,740,933 shares of common stock issuable upon exercise of outstanding
       stock options as of August 31, 2000 at a weighted average exercise price
       of $0.32 per share;

     - 1,930,158 shares of common stock issuable upon exercise of outstanding
       warrants as of August 31, 2000, as adjusted to reflect the conversion of
       preferred stock into common stock, at a weighted average exercise price
       of $0.27 per share; and

     - 1,841,751 shares reserved for future issuance under our stock option,
       director option, and employee stock purchase plans, including amounts
       authorized for issuance subsequent to August 31, 2000.

                                    DILUTION

     If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the pro forma as adjusted net tangible book value per share of
our common stock after this offering.

     Our pro forma net tangible book value at June 30, 2000, was $85.8 million,
or $1.23 per share. Pro forma net tangible book value per share represents the
amount of our pro forma net tangible book value (total assets less intangible
assets and total liabilities) at June 30, 2000 by the pro forma number of
outstanding shares of common stock after giving effect to:

     - the issuance of 83,901 shares of common stock upon the exercise of
       outstanding warrants that, if not exercised by the holders, will expire
       upon the closing of this offering at a weighted average exercise price of
       $0.24 per share;

     - the automatic conversion of all outstanding shares of our preferred stock
       into 70,751,886 shares of common stock upon the closing of this offering;
       and

     - our 2-for-1 common stock dividend, which had the effect of a 3-for-1
       stock split, effective on August 2, 2000.

     Dilution in pro forma net tangible book value per share represents the
difference between the amount per share paid by purchasers of common stock in
this offering and the pro forma net tangible book value per share of common
stock immediately after completion of this offering. After giving effect to the
sale of the                shares of common stock by us at an assumed initial
public offering price of $     per share (less the underwriting discount and
estimated offering expenses payable by us), our pro forma net tangible book
value at June 30, 2000 would have been $     million, or $     per share. This
represents an immediate increase in the pro forma net tangible book value of
$     per share to existing stockholders and an immediate dilution of $     per
share to new investors, or approximately      % of the assumed offering price of
$     per share. 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
"Selected Financial Data" and our financial statements and the related notes
included elsewhere in this prospectus. This discussion contains forward-looking
statements that involve risks and uncertainties. Our actual results could differ
materially from those anticipated in the forward-looking statements as a result
of certain factors including the risks discussed in "Risk Factors" and elsewhere
in this prospectus.

OVERVIEW

     We design, manufacture and sell a family of highly scalable, all-optical,
or photonic, switching subsystems. Our products are based upon our proprietary
implementation of silicon-based micro-electromechanical systems, or MEMS, which
enable optical data streams to be switched among optical fibers entirely in the
optical domain. Our products allow next-generation optical network systems
manufacturers to build scalable, cost-effective optical networking products. An
important competitive advantage and distinction of OMM is our emphasis on
high-volume manufacturing. To that end, we have invested, and expect to continue
to invest, significant capital in the development of automated manufacturing
processes, operations infrastructure and product design to enable us to supply
commercial quantities of our products to customers and to improve our costs by
enhancing manufacturing yields.

     From our inception in June 1997 through April 2000, our operating
activities were primarily devoted to the research and development of our
photonic switching subsystems and automated manufacturing processes. We also
staffed our administrative, marketing and sales organizations and formed
strategic partnerships. In April 2000, we began shipping our photonic switching
subsystems for revenue. Since our inception, we have incurred significant
losses, and as of June 30, 2000, we had an accumulated deficit of $28.1 million.
We have not achieved profitability on a quarterly or annual basis, and
anticipate that we will incur net losses for at least the next several quarters.
We expect to incur significant sales and marketing, research and development and
general and administrative expenses for the foreseeable future and, as a result,
we will need to generate significantly higher revenues to achieve and maintain
profitability.

     Our shipments to date have consisted of our 4x4-port, 8x8-port and
16x16-port photonic switching subsystems. Ports refer to the number of fibers
that enter or exit the subsystem. As of August 31, 2000, we have shipped more
than 100 units to 19 customers. Our customers are utilizing our products in a
variety of ways, including developmental purposes, field trials and early
network deployments. We currently sell through our direct sales force to optical
network systems manufacturers in North America and Europe. We expect that a
significant portion of our revenues will continue to come from sales of our
photonic switching subsystems to a small number of established and emerging
optical network system manufacturers. We have generated substantially all of our
revenues from shipments of units to a limited number of customers, with four
customers accounting for 76% of our revenues for the six months ended June 30,
2000.

     The market for all-optical network systems into which our products are
integrated is new and rapidly evolving. Accordingly, we expect the number,
volume and timing of orders we receive will be difficult to predict. A
customer's decision to purchase our photonic switching subsystems will typically
involve a significant commitment of its resources and a lengthy evaluation and
product qualification process. This initial evaluation and product qualification
process typically takes several months and includes:

     - technical evaluation;

     - integration;

     - testing;

     - network planning; and

     - implementation into the network.

                                       21
<PAGE>   27

     Even after our customers choose to purchase our photonic switching
subsystems, our future orders will be impacted by the timing of deployment of
our customers' systems by communications service providers. Timing of deployment
may vary widely by customer and will depend in part on the technological
capabilities of the service provider, the size of the network deployment, the
complexity of the service provider's network environment and the degree of
hardware configuration necessary to deploy our customers' systems.

     Our cost of revenues includes direct labor, materials and manufacturing
overhead. Materials include amounts paid to suppliers to produce our MEMS chips
and other components. Manufacturing overhead primarily consists of capital
equipment depreciation, facility costs, manufacturing engineering labor and
management and supervisory overhead.

     Research and development expenses consist primarily of salaries and related
personnel costs, fees paid to consultants and outside service providers and
prototype costs related to the design, development, testing and enhancement of
our photonic switching subsystems. We expense our research and development costs
as they are incurred. Several components of our research and development effort
require significant expenditures, the timing of which can cause significant
variability in our quarterly expenses. The number of prototypes required to
build and test a complex product such as our photonic switching subsystems is
large, and the building and testing process occurs over a short period of time.
We also are devoting substantial resources to the continued development of new
products. We believe that research and development is critical to our strategic
product development objectives and that to leverage our leading technology and
meet the changing requirements of our customers, we will need to fund
investments in several development projects in parallel. As a result, we expect
our research and development expenses to increase in absolute dollars in the
future.

     Sales and marketing expenses consist primarily of salaries and related
expenses, for personnel engaged in marketing, sales and customer engineering
support functions, as well as costs associated with promotional and other
marketing expenses. In order to increase market penetration of our products, we
intend to initiate additional marketing programs to support our photonic
switching subsystems and expand our direct sales and support operations by
establishing sales offices in additional domestic and international locations.
Additionally, the complexity of our photonic switching subsystems requires that
we employ highly trained customer service and support personnel to assist our
customers. We expect to expand our customer service and support organization to
meet these requirements. We expect that sales and marketing expenses will
increase in absolute dollars in future periods.

     General and administrative expenses consist primarily of salaries and
related expenses, for executive, finance, accounting, information technology,
and human resources personnel, as well as recruiting expenses, professional fees
and other corporate expenses. We expect general and administrative expenses to
increase in absolute dollars as we add personnel and incur additional costs
related to the planned growth of our business and our operation as a public
company.

     In connection with the grant of stock options to employees during 1999 and
the six months ended June 30, 2000, we recorded a charge for unearned
stock-based compensation of approximately $1.9 million and $42.1 million,
respectively, representing the difference between the value of the common stock
for financial reporting purposes and the exercise price of these options at the
date of grant. Unearned stock-based compensation is presented as a reduction of
stockholders' equity and is amortized over the vesting period of the applicable
options. We expensed approximately $430,000 and approximately $6.7 million of
stock-based compensation during the year ended December 31, 1999, and the six
months ended June 30, 2000, respectively. This compensation expense relates to
stock options awarded to individuals in all operating expense categories and
cost of goods sold. At June 30, 2000, the remaining unearned stock-based
compensation of $36.9 million will be amortized as follows: $11.4 million in the
remainder of 2000, $14.0 million in 2001, $7.5 million in 2002, $3.4 million in
2003 and $563,000 in 2004.

     As of December 31, 1999, we had approximately $8.0 million of federal and
state net operating loss carryforwards and approximately $8.0 million of state
net operating loss carryforwards for tax reporting purposes available to offset
future taxable income. The federal net operating loss carryforwards expire at

                                       22
<PAGE>   28

various dates beginning in 2012, and the state net operating loss carryforwards
expire at various dates beginning in 2005, to the extent that they are not
utilized. We have not recognized any benefit from the future use of loss
carryforwards for these periods, or for any other periods, since inception. Our
analysis of the realizability of the tax benefits of net loss carryforwards
indicates that the underlying assumptions of future profitable operations
contain risks that do not provide us with sufficient assurance to recognize any
tax benefits at this time.

RESULTS OF OPERATIONS

  Revenues

     The quarter ended June 30, 2000 was the first quarter in which we
recognized revenue. Revenues for the six months ended June 30, 2000 were
approximately $413,000. Our total revenues for the six months ended June 30,
2000 were derived from for by eight customers. We generally recognize revenue
from product sales when the product has been shipped. Our products are not
subject to any customer acceptance process. Subsequent to the sale of the
products, we have no obligation to provide any modification or customization,
upgrades, enhancements or any post contract customer support.

  Cost of Revenues

     Cost of revenues for the six months ended June 30, 2000 were approximately
$1.0 million. During prior periods we had no revenues and generated no cost of
revenues. Our gross margin for the six months ended June 30, 2000 was not
meaningful due to significant product startup costs and depreciation which were
allocated over a low volume of products shipped. In future periods our gross
margin will be affected by a number of factors, including the following:

     - our ability to manufacture our photonic switching subsystems in high
       volumes;

     - the manufacturing throughput yields we experience;

     - level of utilization of our manufacturing infrastructure;

     - the mix of products sold;

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

     - material and component costs; and

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

  Research and Development Expenses

     Our research and development expenses for the period from inception to
December 31, 1997, the years ended December 31, 1998, 1999 and the six months
ended June 30, 1999 and 2000 were approximately $31,000, $1.1 million, $6.3
million, $2.0 million, $10.9 million, respectively. The increase in 1999 of
approximately $5.3 million, or 499%, over 1998 was due primarily to increased
costs associated with a significant increase in personnel. The increase in the
six months ended June 30, 2000 of approximately $8.9 million or 447% over the
six months ended June 30, 1999 was due primarily to an increase in prototype
expenses, as well as increased personnel expenses. The increase in 1998 of
approximately $1.0 million over 1997 was due primarily to increased costs
associated with early expansion of our operations. We expect to increase
research and development expenses in absolute dollars in future periods.

  Sales and Marketing Expenses

     We did not recognize any sales and marketing expenses in the period from
inception to December 31, 1997 or in 1998. Sales and marketing expenses for the
year ended December 31, 1999 and for the six months ended June 30, 1999 and
2000, were approximately $23,000, $72,000 and $2.4 million, respectively. The
increases in each period were due primarily to the initiation of sales and
marketing activities and the

                                       23
<PAGE>   29

significant increase in the number of sales and marketing personnel to support
the launch of our products. We expect sales and marketing expenses to increase
in absolute dollars in future periods.

  General and Administrative Expenses

     General and administrative expenses were approximately $23,000, $251,000,
$1.1 million, $364,000 and $5.9 million for periods ended December 31, 1997,
1998, 1999 and for the six months ended June 30, 1999 and 2000. The increase of
approximately $819,000, or 326%, in 1999 compared to 1998 was due primarily to
the increased costs associated with an increase in the number of general and
administrative personnel and increased recruiting, accounting and consulting
activities. The increase of approximately $5.6 million, or 1,525%, for the six
months ended June 30, 2000 over the comparable period in 1999 was also primarily
due to the same factors. The increase in 1998 of approximately $228,000 over
1997 was due primarily to increased costs associated with expansion of our
operations.

LIQUIDITY AND CAPITAL RESOURCES

     Since inception through June 2000, we have financed our operations
primarily through private sales of approximately $103.3 million of equity
securities as well as through approximately $5.3 million of capital leases.

     The Company's redeemable convertible preferred stock has been classified
outside of stockholders' equity based upon accounting guidelines promulgated by
the Securities and Exchange Commission. The preferred stock had a right to
liquidation preferences upon a merger, consolidation or sale or sale of
substantially all of the Company's assets. Solely as a result of these
liquidation provisions the preferred stock is treated as redeemable. The
preferred stock will convert to common stock upon completion of this offering
and these liquidation preferences will terminate. See Note 4 of the notes to our
financial statements.

     We used approximately $5.3 million in cash for operations in 1999, an
increase of $4.1 million from the approximately $1.2 million used in 1998. The
increase was primarily due to an increase in our net loss from approximately
$1.2 million in 1998 to approximately $7.4 million in 1999, partially offset by
increased non-cash charges in 1999. We used approximately $9.2 million in cash
for operations for the six months ended June 30, 2000, as a result of our net
loss of approximately $19.4 million, partially offset by non-cash charges.

     We used approximately $372,000 in cash from investing activities in 1998
and approximately $20.0 million in cash from investing activities in 1999. We
generated approximately $5.1 million in cash in 1998, approximately $23.6
million in cash in 1999 and approximately $78.3 million in cash for the six
months ended June 30, 2000 from financing activities, due primarily to cash
received from private sales of convertible preferred stock. We have used leases
to partially finance capital purchases. In addition, we had approximately $1.6
million in capitalized lease obligations outstanding at December 31, 1999 and
approximately $4.9 million at June 30, 2000.

     We have capital lease financing facilities totaling $13.0 million, of which
$5.8 million was utilized as of June 30, 2000. We have committed to purchase
inventory components costing $3.8 million over various periods ending in 2004.

     Cash and cash equivalents and short-term investments totaled approximately
$20.2 million at December 31, 1999, up from approximately $4.7 million at
December 31, 1998. Most of the increase came from sales of convertible preferred
stock offset, in part, by cash used in operations and the purchase of capital
equipment. At June 30, 2000, cash and cash equivalents and short-term
investments totaled approximately $82.3 million. The increase from December 31,
1999 was due to the receipt of approximately $75.0 million from the sale of
convertible preferred stock in May and June 2000.

     We expect to devote substantial capital resources to continue our research
and development efforts, to hire and expand our sales, support, marketing and
product development organizations, to expand marketing programs, to establish
additional facilities worldwide and for other general corporate activities. We
believe

                                       24
<PAGE>   30

that our current cash balances, together with the proceeds of this offering,
will be sufficient to fund our operations for the next 12 months. However, we
cannot assure you that these cash resources will be sufficient and that we will
not require additional financing within this time frame. Furthermore, if we
require additional funding, we cannot assure you that such funding will be
available on terms acceptable to us or at all.

RECENT ACCOUNTING PRONOUNCEMENTS

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 (SAB 101), "Revenue Recognition in Financial
Statements." The objective of SAB 101 is to provide further guidance on revenue
recognition issues in the absence of authoritative literature addressing a
specific arrangement or a specific industry. We have adopted SAB 101 for all
periods presented.

     In March 2000, the FASB issued FASB Interpretation No. 44 (FIN 44),
"Accounting for Certain Transactions Involving Stock Compensation." We will be
required to adopt FIN 44 effective July 1, 2000 in respect to specific
provisions applicable to new awards, exchanges of awards in a business
combination, modifications to outstanding awards, and changes in grantee status
that occur on or after that date. FIN 44 addresses practice issues related to
the application of Accounting Practice Bulletin Opinion No. 25, "Accounting for
Stock Issued to Employees." We believe that the application of FIN 44 will not
have a material impact on the Company's financial position or results of
operations.

     In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 133 (FAS 133), "Accounting for
Derivative Instruments and Hedging Activities." In May 1999, the FASB delayed
the effective date of FAS 133 by one year. We will be required to adopt FAS 133
for fiscal year 2001. This statement establishes a new model for accounting for
derivatives and hedging activities. Under FAS 133, all derivatives must be
recognized as assets and liabilities and measured at fair value. We believe that
the adoption of this new accounting standard will not have a material impact on
the Company's financial position or results of operations.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET INTEREST RATE SENSITIVITY

     Our exposure to financial market risk, relates primarily to changes in
interest rates affecting our investment portfolio and outstanding debt
obligations. We generally do not attempt to reduce or eliminate our market
exposure on our investment securities because a substantial majority of our
investments are in fixed-rate short-term securities. We do not have any
derivative financial instruments. Due to the short-term nature of our
investments, we believe that there is no material risk. In addition,
substantially all of our outstanding indebtedness is either fixed-rate debt or
short-term variable-rate debt. Therefore, no tabular disclosures have been
presented.

EXCHANGE RATE SENSITIVITY

     We operate primarily in the United States and all sales to date have been
made in U.S. Dollars. Accordingly, we have had no material exposure to foreign
currency rate fluctuations.

                                    BUSINESS

OVERVIEW

     We design, manufacture and sell a family of highly scalable, all-optical,
or photonic, switching subsystems. Our products are based upon our proprietary
implementation of micro-electromechanical systems, or MEMS, which enable all
optical switching of data streams. Our products allow optical network systems
manufacturers to build scalable, cost-effective systems that address next
generation switching needs in the long haul, metropolitan and access segments.

INDUSTRY BACKGROUND

  Increase in Demand for Bandwidth

     Over the past decade, the proliferation of the Internet and an increase in
the transmission of large data files resulting from electronic commerce and
telecommuting have caused a dramatic increase in the volume of traffic traveling
across communications networks. This increase in data traffic, coupled with
demand for enhanced services and improved connection times, has increased demand
for high capacity, or high bandwidth, communications networks. To address large
increases in communications network utilization, communications service
providers are investing significant capital to upgrade and enhance the
capabilities of their networks and to provide flexibility to support future
service offerings and increased bandwidth requirements.

  Evolution of Optical Networks

     Optical networks, which transmit light over glass fibers, can carry
significantly more information over longer distances than electrical signals
traveling over copper wire. Because of this and other characteristics, optical
networking systems provide the most capable solution to address accelerating
bandwidth requirements and, as a result, demand for optical networks is strong
and is expected to accelerate in the coming years. According to RHK, Inc., a
market research and consulting firm, the global optical networking systems
market is projected to increase from $31.5 billion in 1999 to $90.1 billion in
2003.

     A number of factors are driving growth in demand for, and proliferation of,
optical network systems, including:

          Changing Traffic Patterns. The mix of information carried on
     communications networks is rapidly shifting from continuous, low-bandwidth
     streams, such as voice traffic, to large blocks of high-bandwidth data,
     such as computer files and web pages, that are transferred in bursts.
     Because of their inherent capacity, optical networks are well suited to
     handle larger data files and the shift in traffic types.

          Shift to Mesh-based Networks. To address changing traffic patterns and
     to provide increased reliability, service providers are seeking to replace
     networks based on ring topologies with networks based on mesh
     architectures, which use a greater number of network junctions, or nodes.
     Mesh-based architectures are capable of efficiently supporting larger
     amounts of traffic and offer greater redundancy than rings.

          Increasing Fiber Deployments. Communication service providers are
     installing new optical networks to add capacity and are turning on, or
     lighting, previously deployed "dark" fiber optic cables to support
     additional capacity.

          Proliferation of High-capacity Technologies. Widespread deployment of
     technologies such as dense wavelength division multiplexing, or DWDM, which
     uses multiple wavelengths of light simultaneously in a single fiber to
     transmit traffic. For example, individual fibers can now carry as many as
     160 separate wavelengths, each of which is capable of transporting network
     traffic. In addition, data rates for each wavelength are dramatically
     increasing and are now capable of moving data at rates as high as 40
     gigabits per second.

                                       26

  Importance of Switching Technologies

     The combination of these factors has increased the need to efficiently move
traffic onto, around and off of the network. Switches, which control traffic
movement on a network, are becoming an increasingly critical element of the
communications infrastructure. Both electrically based and optically based
switches perform a variety of functions throughout the network, including:

     - shifting traffic from one network branch to another within metropolitan
       areas, or cross-connect switching;

     - directing traffic along various segments of networks between metropolitan
       areas, or core switching;

     - inserting or removing traffic at network junctions and combining it with
       other traffic on the network, or add-drop multiplexing; and

     - providing back-up switching capabilities in the event of a failure on a
       portion of the network, or protection switching.

     The following diagram illustrates a typical communications network and
indicates where switches typically exist.

                                   [DIAGRAM]
     In this place is a graphic of a communications network which encompasses
approximately one-half of the page. Positioned throughout the graphic is the
following text "Backbone/Long Haul Network Mesh," "Regional/Metro Network Ring,"
"Access Network Ring," "Network Core Switch," "Network Core Switch," "Optical
Crossconnect," "Optical Add-Drop Multiplexer (OADM)," "Optical Protection
Switch," "(OADM)," "Optical Protection Switch," "Optical Protection Switch" and
"Customer Premises Equipment."

     Since switches direct network traffic at every network junction, any
improvement to switching technology has the potential to improve overall network
performance. In addition, improving the speed at which data communications
services can be established or changed within a network, or provisioned, has
been an ongoing challenge for communications service providers.
Electrically-based networks have utilized a wide variety of electronic switching
technologies to improve traffic management. However, within optical networks, as
data rates and channel counts increase, traditional switching technologies have
been unable to keep pace with increasing network capacity.

  OEO Switching

     Optical network switches in use today are generally based on a hybrid
technology that first converts optical data streams into electrical signals for
processing. After electronic processing, the information must be converted back
into an optical data stream for transmission to its next destination. These
complex switching systems are known as optical-electrical-optical, or OEO,
systems. OEO switches also require substantial power and central office rack
space to operate. In addition, as the number of fibers and wavelengths in use
increases, the number of OEO switches required to handle network traffic must
also increase. While they have been effectively deployed in optical networks to
date, OEO switches are becoming increasingly incapable of supporting the needs
of emerging next-generation networks. More specifically, OEO switches are
subject to a number of limitations including:

     Fixed Data Rates. OEO switches operate at fixed data rates. If the data
rate in a network is changed, each OEO switch throughout the network must be
manually reconfigured, if possible, or replaced with a faster switch.

     Lack of Transparency. OEO switches lack transparency, or the ability to
pass signals through a switch without regard to transmission protocol or
wavelength. Since OEO switches are designed to support a particular protocol and
are configured to operate with a specific wavelength, they limit network
flexibility. If additional wavelengths are added to the network, the switch must
be upgraded or replaced if it cannot support the increased number of
wavelengths.

     High Total Cost of Ownership. The ability to provision new communications
links rapidly with little or no manual intervention and at a low cost is
becoming essential in the competitive communications services industry. OEO
switching systems typically require costly infrastructure, such as extensive
building and rack space, and electrical power, network management systems and
significant cooling systems to operate reliably. Moreover, adding new services
or changing the configuration of OEO-based switching systems can be very
time-consuming and typically require the dispatch of technicians to network
intersections where switches reside. Due to the labor-intensive and complex
nature of this process, communications service providers often require a long
period of time to fulfill a customer's request to implement new services or
modify existing services, often foregoing revenue opportunities or risking
losing customers.

     Significant Complexity and Lack of Scalability. As additional fibers are
lit, or as more wavelengths, or channels, are deployed in an optical network,
the number of OEO switches must increase as well, adding significant cost and
complexity to the network itself and to its operation. OEO switches require
significant manual intervention and are time-consuming to deploy, and they
cannot easily scale to support more traffic without a commensurate increase in
ancillary infrastructure and equipment.

  Emergence of Photonic Switching

     To address the limitations of OEO switching, optical network systems
manufacturers and communication service providers are seeking switching
technologies based solely on optics whereby optical signals can be added to,
removed from or switched among various optical fibers completely in the optical
domain. These switching technologies are referred to as photonic switching
systems, and they offer the potential to reduce switching bottlenecks and
operating costs by eliminating many of the limitations presented by OEO
switches. Photonic switching systems also facilitate the introduction of new
technologies and services; support multiple, high-speed data rates, protocols
and wavelengths and may be scaled as the network infrastructure evolves. Due to
their cost, performance and scalability advantages, photonic switching systems,
of which our product is a subsystem, are expected to become an integral part of
the communications infrastructure. Pioneer Consulting, a telecom research firm,
forecasts that the market for photonic switching systems in North America and
Europe, will grow from approximately $70 million in 2000 to $7.5 billion in
2004.

  Market Requirements for Photonic Switching Systems

     In order to widely deploy photonic switching systems, optical network
system manufacturers and communication service providers require products that
meet the performance, scalability and cost requirements of next-generation
optical networks. Specifically, photonic switching systems must:

     - utilize switching technologies that are reliable and capable of being
       manufactured in volume;

     - be capable of withstanding rigorous environmental conditions;

     - support high-speed applications, multiple protocols and a wide variety of
       wavelengths;

     - scale cost effectively into large, high port-count configurations as the
       needs of service providers evolve;

     - minimize power and cooling requirements and central office rack space;

     - operate in a number of applications such as optical cross connects,
       optical add-drop multiplexers, bandwidth reprovisioning and protection
       switching, as well as new applications as they are introduced; and

     - lower the total cost of ownership for service providers by reducing their
       initial purchase cost, ongoing maintenance and operational expenses.

  Alternative Photonic Switching Technologies

     Recognizing the growing importance of photonic switching, optical systems
and component manufacturers have been developing several different photonic
switching technologies, including the following: liquid crystal, bubble, lithium
niobate, acousto-optical, optomechanical, thermo-optical and
micro-electromechanical systems, or MEMS. Due to the rigorous performance, cost
and reliability requirements of optical networks, adaptation of the majority of
these technologies for widespread deployment in optical networks has not yet
proven to be practical. In contrast, MEMS-based photonic switching technologies
today offer the potential to deliver the required volume manufacturability,
cost, performance, scalability and reliability needed to address carrier-class
requirements.

THE OMM SOLUTION

     We design, manufacture and sell high performance, highly scalable, photonic
switching subsystems based on our proprietary implementations of silicon-based
MEMS technology. Our photonic switching subsystems are integrated into optical
switching systems that are used in optical networks, which enable our customers

     Carrier-class Reliability. Our products are engineered and rigorously
tested to withstand harsh environmental conditions, including temperature
extremes, shock and vibration. Through our proprietary hermetic packaging
processes, our products are designed to be impervious to outside elements that
can compromise long-term reliability.

     Application Flexibility. Our products are designed for integration in
optical switching systems and can be utilized for a variety of applications for
each segment of the network. Using the same family of products, our customers
can build systems to address multiple applications in between metropolitan
areas, or long haul, within metropolitan areas, or connecting end users within a
metropolitan area with access segments, thereby leveraging their product
development investments.

     We believe that our products and technologies offer a combination of
scalability, flexibility, performance and reliability, which enables us to
deliver high-value photonic switching products to customers worldwide.

  Future Products

     We are enhancing our 2D product family to expand port capacities as well as
to add new capabilities. In 2001, we intend to introduce a 32x32-port photonic
switching subsystem. By cascading these products, our customers will be able to
build very dense, scalable systems up to 512x512 ports. We also plan to extend
our 2D product line to include enhanced features and functionality, at both the
electronics and optoelectronics levels. We intend to manufacture a range of new
products that may include capabilities such as variable optical attenuation,
optical monitoring, wavelength selection and zero signal loss. In addition, we
intend to enhance the functionality of our switching products by incorporating
combinations of these capabilities into a single package. We believe these
integrated subsystems will enable substantial cost saving to our customers and
create additional opportunities for us in the metropolitan area and enterprise
level markets.

     We also plan to introduce a 3D switching subsystem in late 2001 based on a
proprietary scanning mirror design. Our 3D products will be designed to enable
optical network systems manufacturers to provide very large-scale optical
crossconnect switching capabilities to many thousands of ports. With the
combination of 2D and 3D switching products, it is our intention to offer our
customers the broadest possible range of switch densities in the photonic
switching industry.

CUSTOMERS AND STRATEGIC PARTNERSHIPS

     We are currently shipping our products to 20 optical network systems
manufacturers worldwide. Following are our top five customers based on revenues
since we began shipping our products in April 2000 to date:

<TABLE>
<S>                                            <C>

 Nortel Networks Corporation                   Siemens AG
 Sorrento Networks, Inc.
</TABLE>

     For the six months ended June 30, 2000, each of Corvis, Siemens AG, Nortel
Networks and ilotron Ltd. accounted for at least 10% of our sales. As a group,
these four customers accounted for 76% of our total sales for the same period.

     As part of our strategy to enable our customers to shorten their product
development cycles and improve their time to market, we enter into strategic
partnerships with current and potential customers. To date we have entered into
partnerships with the following entities:

     Alcatel

     In May 2000, we entered into an agreement with the Alcatel Optics Group, a
business group of Alcatel SA, to collaborate in the development of a large
optical crossconnect subsystem based upon 3D optical MEMS switching technology.
This collaboration is intended to enable us to utilize input from Alcatel's
development teams to develop 3D products faster than if developed alone. Alcatel
has announced that it intends to encompass these products into its
Crosslight(TM) product portfolio. In addition, we have been working with Alcatel
to design protection switching systems based upon our 2D products. Alcatel has
also made an equity investment in OMM.

     Siemens

     We have been working with Siemens AG to design optical crossconnect
subsystems based upon our 2D optical MEMS switching technology. Siemens has
announced that it is using our 2D product in their TransXpress(TM) Optical
Service Node optical crossconnect system. Siemens has also made an equity
investment in OMM.

     Sycamore Networks

     In August 2000, we entered into a non-exclusive letter of intent with
Sycamore Networks to collaborate in the development of a large optical
crossconnect subsystem based upon 3D optical MEMS switching technology. This
collaboration is intended to enable us to utilize input from Sycamore Networks'
development teams to develop 3D products more rapidly than if we were to develop
them independently. Sycamore has also made an equity investment in OMM.

TECHNOLOGY

  Background

     Using semiconductor and semiconductor fabrication technology, researchers
have been able to construct highly miniaturized versions of most common optical
components, including lenses, mirrors, diffraction gratings and solid state
lasers. Also fabricated using semiconductor processing technology, MEMS are
miniature assemblies that perform mechanical tasks when electrical energy is
applied to them. The combination of semiconductor-scale optics and MEMS
technology is currently being utilized to address a variety of emerging optical
applications, including photonic switching.

     A MEMS-based photonic switch consists of extremely small, movable mirror
assemblies on the surface of a silicon chip. When electrical current is applied
to the individual assemblies, the angle of the mirror surface can be adjusted to
deflect incoming light beams from optical fibers with extreme precision. These
assemblies can be combined with micro-optics and aligned to optical fibers to
create highly compact photonic switches capable of rapid signal switching among
dense optical fiber arrays. Both the micro-optics and MEMS mirror assemblies are
fabricated on silicon wafers using well-established, very large scale
integration, or VLSI, semiconductor fabrication technology and, accordingly,
they have proven to be highly reliable and scalable in their manufacture.

  MEMS Design Expertise

     MEMS technology represents a relatively new field of technology that began
to find use in commercial applications only within the past decade. The first
volume applications of MEMS technology have included a variety of sensor
applications, including automobile air bag acceleration sensors, and overhead
projection displays. Our use of MEMS technology represents one of the first
commercial deployments of MEMS for optical applications. Using MEMS technology
to create a photonic switch required us to overcome substantial engineering
hurdles such as establishing an unusually high range of motion and actuation
forces on the MEMS structures.

     Because of the criticality of MEMS design to our product, we have assembled
a highly experienced engineering team focused on optical MEMS design. Our team
has extensive knowledge in the areas of multi-layer polysilicon processing, MEMS
structure and release design and electrostatic actuation methods. In addition,
this team has been able to develop an extensive MEMS design library, including
such elements as torsion bars, hinges, springs, struts, gimbals and
electrostatic actuators. We believe our MEMS design resources represent a
substantial competitive advantage.

  Our Switch Architectures

     There are two prevailing design approaches for creating photonic switches
utilizing MEMS technology: two-dimensional, also known as 2D, or digital
architecture, and three-dimensional, also known as 3D, or analog architecture.

     Our 2D digital approach utilizes micro-mirrors and associated optical
fibers arranged in a two-dimensional, planar fashion. The micro-mirrors can
occupy one of two positions, either on or off, at any given time. In this
approach, an array of MEMS micro-mirrors is used to connect a given number, or
N, input fibers to N output fibers and, accordingly, is referred to as an N(2)
architecture because its design requires N(2) individual mirrors. For example,
an 8x8 2D switch requires 64 micro-mirrors. Benefits of this architecture are
the optical performance, reliability and cost-effectiveness derived from its
design simplicity

                                       34
<PAGE>   40

and its requirement for relatively simple control circuitry for mirror
positioning. Our 2D architecture also supports the introduction of a third and
fourth fiber array, as shown in the figure below, to a basic 2D switch to permit
adding and dropping of optical signals. Our 2D switches can also be cascaded to
form a multistage architecture scalable to hundreds-by-hundreds of ports.

                    2D PHOTONIC DIGITAL SWITCH ARCHITECTURE

                                    GRAPHIC

     In this place is a graphic of a 2D Photonic Digital Switch Architecture
which encompasses approximately one-fourth of the page. Positioned in the
graphic is the following text "MEMS Mirrors" and "Optical Fibers."

     Our 3D analog, or beam-steering, approach uses the same principle of moving
micro-mirrors to redirect light. However, in our 3D architecture, the mirror
structures are movable along two separate axes, directing the beam through three
dimensions to multiple possible positions. Our 3D architecture utilizes two
arrays of micro-mirrors to connect N input fibers to an equal number of output
fibers which results in a switch utilizing 2N micro-mirrors. Although more
complex, the 3D architecture is more scalable than the 2D architecture as the
port count grows and, as a result, our 3D architecture can scale to thousands-
by-thousands of ports. Because the two-axis micro-mirror must be capable of
multiple possible positions, a sophisticated sensing and analog control scheme
must be implemented to ensure that the mirrors are each in their correct
positions at all times. We utilize a closed-loop control scheme that monitors
mirror positions on a real-time basis to ensure precise mirror alignment. We
believe that a closed-loop position

                                       35
<PAGE>   41

monitoring scheme is fundamental to achieve the beam stability required in
carrier-class deployment of a 3D photonic switch.

the graphic is the following text "3D Photonic Switch Architecture," "Input
fibers," "Director (selects output channel)," "Redirector (ensures coupling into
output fibers)," "Input collimators," "Output collimators" and "Output fibers."

  Manufacturing and Packaging Technology

     As part of our business strategy we have chosen to retain several
proprietary manufacturing processes in-house and outsource other, less
proprietary manufacturing steps to selected third-party partners. Since the
micro-optics and MEMS-based mirror assemblies are fabricated on silicon wafers
using standard semiconductor fabrication technology, we have these parts
manufactured for us by multiple semiconductor foundry partners. The
manufacturing processes that we perform internally include:

     - MEMS wafer dicing;

     - MEMS structure release and actuation;

     - fiber array and micro-lens array alignment to produce collimator arrays;

     - MEMS and collimator array alignment and fixing in place;

     - fiber feedthrough sealing and overall package sealing; and

     - in-process and final subsystem testing.

     Our MEMS-based photonic switching subsystems must be assembled in a
cleanroom environment and be sealed in specially designed, hermetic packages to
achieve and maintain the durability, reliability and performance required by our
customers. Photonic switches require critical alignments of optical components
and fibers and hermetic feedthroughs within the package to allow for the entry
and exit of multiple optical fiber arrays and electrical connections. Using our
proprietary designs and assembly techniques, we integrate the MEMS mirror
control electronics, micro-optics and micro-mirror assembly within the same
hermetically sealed package. This internal integration is designed to
significantly improve reliability, simplify manufacturability and eliminate
shifting and misalignment due to environmental effects such as temperature
extremes, shock and vibration. Incorporating the control electronics also
significantly reduces the number of package feedthroughs required. We have
devoted substantial development resources to the design and fabrication of our
photonic switch packaging. We believe that our packaging expertise represents a
distinctive competitive advantage.

                                       36
<PAGE>   42

  Automation

     We have designed our products to be manufacturable in high volume. We have
automated our manufacturing processes in order to achieve the high production
volumes required for current and anticipated future market requirements, as well
as maintaining control of our product quality, cycle times and costs. We
continue to devote substantial internal and external engineering resources to
further our automation capabilities. Additionally, we have custom-designed many
of the tools and equipment required for automated manufacturing of our products,
which we believe represents a competitive advantage.

MARKETING, SALES AND CUSTOMER SERVICE

     We market and sell our subsystems to established and emerging optical
network systems manufacturers worldwide through our direct sales force. As of
August 31, 2000, we had ten individuals in our sales and marketing department,
all of whom are based in the United States. Our product marketing efforts
consist primarily of participation in trade shows and industry conferences,
direct marketing to customers and developing industry contacts. For the year
ended December 31, 1999 and the six months ended June 30, 2000, our sales and
marketing expenses were approximately $23,000 and $2.4 million, respectively.

RESEARCH AND DEVELOPMENT

     We have assembled a team of engineers, technicians and operators with
significant experience in the fiber optics industry, other industries with high
precision manufacturing requirements such as the semiconductor, semiconductor
capital equipment and optical storage and the communications industries. Our
team also has expertise in optics, fiber optic package design, optoelectronics
and system architecture. We invest substantial resources in both new product and
manufacturing process development. Our product development efforts focus on
high-speed optoelectronics, fiber alignment, advanced automation techniques and
test and optical systems design. As of August 31, 2000, we employed 62
individuals engaged in research and development activities. Of these, the
majority hold advanced degrees, including 26 employees with doctorate degrees.

     We have made, and will continue to make, a substantial investment in
research and development. Our research and development expenses totaled
approximately $1.1 million for our fiscal year ended December 31, 1998, $6.3
million for our fiscal year ended December 31, 1999 and $10.9 million for the
six months ended June 30, 2000.

MANUFACTURING AND OPERATIONS

     We consider manufacturing to be one of our core competencies and consider
our manufacturing processes to be a significant competitive advantage. To that
end we have invested, and expect to continue to invest, significant capital into
designing and implementing our manufacturing processes and operations
infrastructure. We have made significant efforts to design our products to be
manufacturable in high volume and to ensure that product designs are continually
optimized for manufacturability. Similarly, we have invested substantial
resources aimed at automating much of the manufacturing process. To this end, we
have designed and implemented several proprietary automated and semi-automated
manufacturing systems and processes which should enable us to lower product
costs and increase manufacturing yields. We have developed proprietary automated
systems and processes to:

     - dice silicon wafers to maximize the number of usable MEMS chips;

     - release, lift and activate the mirror structures on the MEMS chips;

     - align and attach fibers to optical components, such as lenses, within the
       subsystem package;

     - position our fiber arrays in proper alignment with the MEMS chips;

     - integrate drive electronics; and

     - assemble, package and hermetically seal the switching subsystem.

                                       37
<PAGE>   43

     We currently manufacture our products in 5,000 square feet of manufacturing
space that includes approximately 2,000 square feet of cleanroom area. We are
completing construction of an additional manufacturing area in our second San
Diego area facility that will includes more than 20,000 square feet of cleanroom
area. This new facility is scheduled for completion in the fourth quarter of
2000.

     We obtain several key components and manufacturing systems from limited or
sole-source suppliers, including collimating lenses, fiber array substrates,
MEMS assembly equipment, and align and fix tools. We intend to locate additional
sources of supply for each of these components, including collimating lenses and
fiber array substrates. However, we cannot assure you that we will be able to
find alternative sources of supply for any of these components. We purchase
these components and systems from their respective manufacturers subject to
purchase orders that we place from time to time. We provide rolling forecasts to
our suppliers and currently maintain inventory levels of key components to
facilitate our ability to meet customer orders. However, demand for the
components and systems that we use is high, and we may, in the future,
experience interruptions or delays in supply of key components, several of which
have long order lead times. We also may experience manufacturing yield
fluctuations that could impact material supply due to increased in-process
scrap, which could impact shipments to customers. If we are unable to obtain
sufficient quantities of components, obtain components available only from our
sole source suppliers, or receive materials in a timely manner, we may be unable
to ship our product to customers as scheduled or may be forced to redesign
portions of our products, which would be costly and time consuming.

     As of August 31, 2000, we employed 110 people in manufacturing and
operations.

COMPETITION

     The market for optical switching systems is new, rapidly changing and
intensely competitive. We compete with a number of companies that address the
optical switching market, including optical network systems manufacturers, other
subsystems manufacturers and companies that supply various components of optical
switching systems. In addition, we compete with vendors of OEO switches who will
continue to advocate the use of their products in optical networks. We believe
that the principal bases of competition in our market are the speed and
scalability of photonic switches, their total cost of ownership, reliability and
versatility of applications. We believe that we compete favorably in each of
these areas.

     We face competition from a number of large, established public companies,
such as Agilent Technologies, Corning Incorporated, JDS Uniphase Corporation,
Lucent Technologies' Microelectronics Division and Nortel Networks, that offer a
wide range of components and subsystems to optical network systems
manufacturers. In addition, a number of private companies have announced plans
for all-optical switching products to address many of the same applications that
our products address. We also compete with several companies, such as
PMC-Sierra, Inc. and Applied Micro Circuits Corporation, that provide OEO
products to optical network systems manufacturers. Moreover, some of our
customers may develop all-optical switching subsystems that compete with our
products.

     Many of our current and potential competitors have longer operating
histories and significantly greater financial, technical, marketing and other
resources than we have. As a result, these competitors may be able to devote
greater resources than we can to the development, promotion, sale and support of
their products. In addition, several of our competitors that have larger market
capitalizations or cash reserves than we do and may be better positioned than we
are to acquire other companies in order to gain new technologies or products
that may displace our products. In addition, many of our competitors have much
greater name recognition, more extensive customer bases, better-developed
distribution channels and broader product offerings than we have. These
companies can leverage their customer bases and broader product offerings and
adopt aggressive pricing policies to gain market share.

INTELLECTUAL PROPERTY RIGHTS

     Our success and ability to compete depend substantially upon our internally
developed technology. We have filed five U.S. patent applications and have filed
four international patent applications pursuant to the Patent Cooperation
Treaty. We cannot assure you that our patent applications will be approved, that
any

                                       38
<PAGE>   44

patents that may issue will protect our intellectual property or that any issued
patents will not be challenged by third parties.

     While we rely on a combination of patent, copyright, trademark, service
mark and trade secret laws and contractual restrictions to establish and protect
our intellectual property, we also believe that factors such as the
technological and creative skills of our personnel, new technology developments,
frequent technology enhancements and reliable product maintenance are essential
to establishing and maintaining a technology leadership position. We cannot
assure you that others will not develop technologies that are similar or
superior to our technology.

     We generally enter into confidentiality agreements with our employees,
consultants and corporate partners, and generally control access to and
distribution of our proprietary information. We request that our corporate
partners and others who may be given access to our proprietary information sign
non-use and non-disclosure agreements. Despite these efforts to protect our
proprietary rights, unauthorized parties may attempt to copy or otherwise obtain
and use our technology. Policing unauthorized use of technology is difficult,
and there can be no assurance that the steps taken by us will prevent
misappropriation of our technology, particularly in foreign countries where the
laws may not protect our proprietary rights as fully as do the laws of the
United States.

     Substantial litigation regarding intellectual property rights exists in the
networking industry, and we expect that optical communications products may be
increasingly subject to third-party infringement claims as the number of
competitors in our industry segment grows. We believe that we own or have the
right to use the basic patents covering our products. However, the networking
industry is characterized by a very large number of patents, many of which are
of questionable validity and some of which appear to overlap with other issued
patents. We have received limited product development funding from U.S.
government agencies. We cannot assure you that the U.S. government will not
attempt to assert intellectual property rights pursuant to our agreements with
these agencies. In addition, we believe that many of our competitors in the
networking industry have filed or intend to file patent applications covering
aspects of their technology on which they may claim infringement by us with
respect to our products. Because patent applications can be maintained in
secrecy in the United States until such patents are issued and are maintained in
secrecy for a period of time outside of the United States, we are conducting
only limited searches to determine whether our technology infringes any patents
or patent applications of others.

     We cannot make any assurances that other third parties will not claim
infringement by us with respect to our products and our associated technology.
In the future, we may be a party to litigation to protect our intellectual
property or as a result of an alleged infringement of others' intellectual
property. These claims and any resulting lawsuit, regardless of our success,
would likely be time-consuming to defend, subject us to significant litigation
costs, divert management's attention and resources, cause product shipment
delays or require us to enter into royalty or licensing arrangements. Any
potential intellectual property litigation also could force us to do one or more
of the following:

     - stop selling, incorporating or using our products that use the infringed
       intellectual property;

     - obtain from the owner of the infringed intellectual property a license to
       sell or use the relevant technology, which license may not be available
       on terms acceptable to us, if at all; and

     - redesign our products that use the technology.

     If we are forced to take any of these actions, our business may be
seriously harmed. A successful claim of intellectual property infringement
against us and the failure or inability by us to license the infringed or
similar technology or redesign our products could seriously harm our business.

     We may in the future initiate claims or litigation against third parties
for infringement of our proprietary technology to protect our intellectual
property or determine the scope and validity of our proprietary rights or the
proprietary rights of our competitors. These claims could result in costly
litigation and the diversion of our technical and management personnel.

EMPLOYEES

     As of August 31, 2000, we had 211 full-time employees, 62 of whom were in
research and development, 110 were in manufacturing and quality assurance, 10
were in sales and marketing, and 29 were in general and administrative
functions. None of our employees is represented by a labor union or subject to a
collective bargaining agreement. We have not experienced any work stoppages and
we consider our relations with our employees to be good.

FACILITIES

     Our corporate headquarters facility, of approximately 21,000 square feet,
is located in San Diego, California. We lease our corporate headquarters
facility pursuant to a lease agreement that expires in June 2004, subject to our
one-time option to extend the lease for an additional three-year period. In
August 2000, we began expanding our operations to a second facility of
approximately 100,000 square feet. We lease this second facility pursuant to a
lease agreement that expires in July 2009, subject to our one-time option to
extend the lease for an additional three-year period. We anticipate that we will
need to secure additional space for our operations within the next twelve
months.

LEGAL PROCEEDINGS

     We are not currently subject to any material legal proceedings.

BOARD OF DIRECTORS

     Our board of directors currently consists of five members and two vacant
positions. Upon completion of this offering, our certificate of incorporation
will provide for a classified board of directors consisting of three classes of
directors, each serving staggered three-year terms. As a result, a portion of
our board of directors will be elected each year. To implement the classified
structure, prior to the consummation of the offering, two of the members to the
board of directors will be elected to one-year terms, two will be elected to
two-year terms and two will be elected to three-year terms. Thereafter,
directors will be elected for three-year terms. Hus Tigli and Barry Fidelman
have been designated Class I Directors, whose terms expire at the 2001 annual
meeting of stockholders. Stephen Domenik and Bruce Graham have been designated
Class II Directors, whose terms expire at the 2002 annual meeting of
stockholders. Anis Husain has been designated a Class III Director and two seats
are vacant, whose terms expire at the 2003 annual meeting of stockholders. This
classification of the board of directors may delay or prevent a change in
control of our company or in our management. See "Description of Capital
Stock -- Delaware Anti-Takeover Law and Certain Charter and Bylaw Provisions."

     Executive officers are appointed by the board of directors on an annual
basis and serve until their successors have been elected and qualified. There
are no family relationships among any of our directors, officers or key
employees.

Board Committees

  Audit Committee

     We established an audit committee in June 2000. The audit committee
consists of Stephen Domenik, Barry Fidelman and Bruce Graham. The audit
committee reviews our internal accounting procedures and consults with and
reviews the services provided by our independent accountants.

  Compensation Committee

     We established a compensation committee in June 2000. The compensation
committee consists of Stephen Domenik, Barry Fidelman and Bruce Graham. The
compensation committee reviews and recommends to the board of directors the
compensation of all of our officers and directors, including stock compensation
and loans and establishes and reviews general policies relating to the
compensation and benefits of our employees.

     Compensation Committee Interlocks and Insider Participation

     Prior to establishing the compensation committee, the board of directors as
a whole performed the functions delegated to the compensation committee. No
member of the board of directors or the compensation committee serves as a
member of the board of directors or compensation committee of any entity that
has one or more executive officers serving as a member of our board of directors
or compensation committee.

     Director Compensation

     We do not currently compensate our directors in cash for their service as
members of the board of directors, although they are reimbursed for expenses in
connection with attending board of directors and committee meetings. Our 1997
Stock Plan provides for the automatic grant of non-statutory stock options to
non-employee directors. For further information regarding the provisions of the
1997 Stock Plan, see "-- Employee and Director Benefit Plans."

     Limitations on Directors' Liability and Indemnification

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

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

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

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

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

     The limitation of liability does not apply to liabilities arising under the
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission.

     Our certificate of incorporation and bylaws provide that we will indemnify
our directors and officers and may indemnify our employees and other agents to
the fullest extent permitted by law. We believe that indemnification under our
bylaws covers at least negligence and gross negligence on the part of
indemnified parties. Our bylaws also permit us to secure insurance on behalf of
any officer, director, employee or other agent for any liability arising out of
his or her actions in their capacity as an officer, director, employee or other
agent, regardless of whether the bylaws would permit indemnification.

     We have entered into agreements to indemnify our directors, executive
officers and controller, in addition to the indemnification provided for in our
bylaws. These agreements, among other things, provide

                                       43
<PAGE>   49

for indemnification of our directors, executive officers and controller for
judgments, fines, settlement amounts and certain expenses, including attorneys'
fees incurred by the director, executive officer or controller in any action or
proceeding, including any action by or in the right of OMM, arising out of the
person's services as a director, executive officer or controller of us, any of
our subsidiaries or any other company or enterprise to which the person provides
services at our request. We believe that these provisions and agreements are
necessary to attract and retain qualified persons as directors and executive
officers.

     The limited liability and indemnification provisions in our certificate of
incorporation and bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful, might otherwise benefit us and our
stockholders. A stockholder's investment in us may be adversely affected to the
extent we pay the costs of settlement or damage awards against our directors and
officers under these indemnification provisions.

     At present, there is no pending litigation or proceeding involving any of
our directors, officers or employees in which indemnification is sought, nor are
we aware of any threatened litigation that may result in claims for
indemnification.

OPTION GRANTS IN FISCAL YEAR 1999

     The following table shows certain information regarding stock options
granted to the Named Executive Officers during the fiscal year ended December
31, 1999. All of these stock options were granted under our 1997 Stock Plan and
have a term of ten years, subject to earlier termination in the event the
optionees' services to us cease. See "-- Employee and Director Benefit Plans"
for a description of material

                                       44
<PAGE>   50

terms of these stock options. See "Transactions with Related Parties and
Insiders" for a description of the exercises of stock options granted to the
Named Executive Officers under the 1997 Stock Plan.

     In accordance with the rules of the Securities and Exchange Commission,
also shown below is the potential realizable value over the term of the option,
or the period from the grant date to the expiration date, based on assumed rates
of stock appreciation of 5% and 10%, compounded annually. These amounts are
based on certain assumed rates of appreciation and do not represent our estimate
of our future stock price. Potential realizable values are computed by:

     - multiplying the number of shares of common stock underlying each option
       by the fair market value of our common stock on the date of grant;

     - assuming that the total stock value derived from that calculation
       compounds at the annual 5% or 10% rate shown in the table for the entire
       ten-year term of the option; and

     - subtracting from that result the total option exercise price.

     Actual gains, if any, on stock option exercises will be dependent on the
future performance of the common stock.

AGGREGATE OPTION EXERCISES IN FISCAL YEAR 1999 AND FISCAL YEAR-END OPTION VALUES

     The following table sets forth information with respect to the Named
Executive Officers concerning option exercises for the fiscal year ended
December 31, 1999, and exercisable and unexercisable options held as of December
31, 1999. None of the executive officers listed in the table below exercised any
of their options during the fiscal year ended December 31, 1999.

     The fiscal year-ended value of in-the-money stock options represents the
difference between the exercise price of such options, and the fair value of our
common stock as of December 31, 1999. The fair value of our common stock on
December 31, 1999 for financial reporting purposes on such date was $0.74 per
share. The actual value of in-the-money stock options will depend upon the
trading price of our common stock on the date of sale of the underlying common
stock and may be higher or lower than the amount set forth in the table above.
The values of unexercised in-the-money options are computed by:

     - multiplying the deemed fair market value per share by the number of
       shares, and

     - subtracting the result of multiplying the exercise price per share by the
       number of shares.

EMPLOYEE AND DIRECTOR BENEFIT PLANS

  1997 Stock Plan

     Our 1997 Stock Plan provides for the grant of incentive stock options to
employees and nonstatutory stock options, options and stock purchase rights to
employees, directors and consultants. The 1997 Stock Plan was adopted by our
board of directors in October, 1997 and approved by our stockholders in
September 1998. Our board of directors and stockholders approved amendments to
the 1997 Stock Plan to increase the number of shares reserved under the 1997
Stock Plan in September 15, 2000.

     As of September 15, 2000, total of 35,050,000 shares of common stock have
been reserved for issuance under the 1997 Stock Plan. An annual increase will be
added on the first day of our fiscal year, beginning in 2002, equal to the
lesser of:

     - 6,500,000 shares;

     - 5.0% of the outstanding shares on that date; or

     - a lesser amount determined by the board of directors.

     As of September 15, 2000 options to purchase 14,045,445 shares of common
stock were outstanding and 16,550,750 shares were available for future grant
(including the 14,000,000 shares reserved for issuance on September 15, 2000).

  Administration

     Our board of directors or a committee of our board of directors administers
the 1997 Stock Plan. The administrator of our 1997 Stock Plan has the power to
determine, among other things:

     - the terms of the options or stock purchase rights granted, including the
       exercise price of the option or stock purchase right;

                                       46
<PAGE>   52

     - the number of shares subject to each option or stock purchase right;

     - the exercisability of each option or stock purchase right; and

     - the form of consideration payable upon the exercise of each option or
       stock purchase right.

  Options

     The exercise price of all incentive stock options granted under the 1997
Stock Plan must be at least equal to the fair market value of the common stock
on the date of grant. The exercise price of nonstatutory stock options and stock
purchase rights granted under the 1997 Stock 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 Internal Revenue Code, the exercise price must be at least equal to the
fair market value of our 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 our 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 1997 Stock Plan may not
exceed ten years.

     During any fiscal year, each optionee may be granted options to purchase a
maximum of 1,000,000 shares. In addition, in connection with an optionee's
initial employment with us, the optionee may be granted an option covering an
additional 1,500,000 shares.

     Options granted under the 1997 Stock Plan must generally be exercised
within three months after the end of optionee's status as an employee, director
or consultant of ours, or within 12 months after the optionee's termination by
death or disability, but in no event later than the expiration of the option's
term.

  Automatic Option Grants to Non-Employee Directors

     Our 1997 Stock Plan also provides for the automatic grant of 45,000 shares
of common stock to a director who first becomes a non-employee director, except
those directors who become non-employee directors by ceasing to be employee
directors, on or after the date of this offering. This option will vest as to
15,000 of the shares subject to the option on each anniversary of the date of
grant. Each non-employee director will automatically be granted an option to
purchase 10,000 shares each year following the date of our annual stockholders'
meeting except after the first such annual meeting if it is held within six
months of the date of this offering, if on such date, he or she will have served
on our board of directors for at least the previous six months. This option will
vest as to one hundred percent of the shares subject to the option on each
anniversary of the date of grant. All options automatically granted to
non-employee directors will have a term of ten years and the exercise price will
be one hundred percent of fair market value per share of common stock on the
date of grant.

  Vesting

     Options and stock purchase rights granted under our 1997 Stock Plan
generally become exercisable at the rate of 1/4 of the total number of shares
subject to the option twelve months after the date of grant, and 1/48 of the
shares subject to the option each month thereafter.

  Transferability of Options

     Options and stock purchase rights granted under the 1997 Stock Plan are
generally not transferable by the optionee, and each option and stock purchase
right is exercisable during the lifetime of the option only by the optionee.

                                       47
<PAGE>   53

  Stock Purchase Right

     In the case of stock purchase rights, unless the administrator determines
otherwise, the restricted stock purchase agreement shall grant us a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's employment or consulting relationship with us for any reason,
including death or disability. The purchase price for shares repurchased
pursuant to the restricted 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 us. The repurchase option shall lapse at a rate determined by the
administrator.

  Adjustments upon Merger or Asset Sale

     The 1997 Stock Plan provides that in the event of our merger with or into
another corporation, or a sale of substantially all of our assets, the successor
corporation will assume each option and stock purchase right or substitute an
equivalent option. If the outstanding options and stock purchase rights are not
assumed or substituted by the successor corporation, the optionees will become
fully vested in and have the right to exercise such options or stock purchase
rights. If an option or stock purchase right becomes fully vested and
exercisable in the event of a merger or sale of assets, the administrator must
notify the optionee that the option or stock purchase right is fully exercisable
for a period of 15 days from the date of the notice, and the option or stock
purchase right will terminate upon the expiration of the 15-day period.

  Amendment and Termination of the 1997 Stock Plan

     The administrator will have the authority to amend, suspend or terminate
the 1997 Stock Plan, so long such action does not affect any shares of common
stock previously issued and sold or any option previously granted under the 1997
Stock Plan. Unless earlier terminated, the 1997 Stock Plan will terminate
automatically 10 years from the date of obtaining stockholder approval of the
amended plan in October 2007.

2000 STOCK PURCHASE PLAN

     Our 2000 Stock Purchase Plan was adopted by our board of directors on
September 15, 2000, and will be effective upon completion of this offering,
subject to stockholder approval. The 2000 Stock Purchase Plan provides our
employees with an opportunity to purchase our common stock through accumulated
payroll deductions. A total of 4,000,000 shares of common stock have been
reserved for issuance under the 2000 Stock Purchase Plan, none of which had been
issued as of the date of this prospectus. An annual increase will be added on
the first day of our fiscal year, beginning in 2001, equal to the lesser of:

                - 2,700,000 shares;

                - 2% of the outstanding shares on that date; or

                - a lesser amount determined by the board of directors.

     The 2000 Stock Purchase Plan will be administered by our board of directors
or by a committee appointed by the board of directors.

  Structure of the 2000 Stock Purchase Plan

     The 2000 Stock Purchase Plan, which is intended to qualify under Section
423 of the Internal Revenue Code, provides consecutive twenty-four month
offering periods with consecutive, six-month purchase periods. The offering
periods generally start on the first trading day on or after February 1 and
August 1 of each year, except for the first 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 January 1, 2003.

  Eligibility

     Employees are eligible to participate if they are customarily employed by
us or any participating subsidiary for at least 20 hours per week and more than
five months in any calendar year. However, employees may not be granted an
option to purchase stock under the 2000 Stock Purchase Plan if they either:

     - immediately after grant, own stock possessing 5% or more of the total
       combined voting power or value of all classes of our capital stock; or

     - hold rights to purchase stock under our employee stock purchase plans
       which accrue at a rate which exceeds $25,000 worth of stock for each
       calendar year.

  Purchases

     The 2000 Stock Purchase Plan permits participants to purchase our 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, exclusive of payments for overtime, shift
premium, incentive compensation, incentive payments, bonuses and other
compensation. The maximum number of shares a participant may purchase during a
single purchase period is 10,000 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 2000 Stock Purchase Plan is generally 85% of the lower of
the fair market value of the common stock either:

     - at the beginning of the offering period; or

     - at the end of the purchase period.

     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 us.

  Transferability of Rights

     Rights granted under the 2000 Stock Purchase Plan are not transferable by a
participant other than by will, the laws of descent and distribution, or as
otherwise provided under the 2000 Stock Purchase Plan.

  Merger or Asset Sale

     The 2000 Stock Purchase Plan provides that, in the event we merge with or
into another corporation or there is a sale of substantially all of our assets,
the successor corporation will assume each outstanding option or substitute an
equivalent option. If the successor corporation refuses to assume or substitute
the outstanding options, the offering period then in progress will be shortened
and a new exercise date, before the date of our proposed merger or sale, will be
set.

  Amendment and Termination of the 2000 Stock Purchase Plan

     The 2000 Stock Purchase Plan will terminate in 2010. Our board of directors
has the authority to amend or terminate the 2000 Stock Purchase Plan, except
that no such action may adversely affect any outstanding rights to purchase
stock under the 2000 Stock Purchase Plan.

401(K) PLAN

     In August 1999, we adopted a Retirement Savings and Investment Plan, or
401(k) plan, covering our eligible employees located in the United States. The
401(k) Plan is intended to qualify under Section 401(a) of the Internal Revenue
Code of 1986, as amended. All contributions to the 401(k) Plan by eligible
employees or by us, and the investment earnings thereon, are not taxable to such
employees until withdrawn, and any contributions we may make are expected to be
deductible by us when made. Our eligible employees may elect to reduce their
eligible compensation by up to 25%, subject to statutorily
                                       49
<PAGE>   55

prescribed limits, and to have such compensation reductions contributed on their
behalf to the 401(k) Plan. The 401(k) Plan permits, but does not require, us to
make matching contributions to the 401(k) Plan.

                 TRANSACTIONS WITH RELATED PARTIES AND INSIDERS

     Other than compensation agreements and other arrangements, which are
described as required in "Management," and the transactions described below,
since our inception in June 1997, there has not been, nor is there currently
proposed, any transaction or series of similar transactions to which we were or
will be a party:

     - in which the amount involved exceeded or will exceed $60,000; and

     - in which any director, executive officer, or holder of more than 5% of
       our common stock on an as-converted basis or any member of their
       immediate family had or will have a direct or indirect material interest.

     We believe that each of the transactions described below were on terms no
less favorable than could have been obtained from unaffiliated third parties.

  LOAN TO EXECUTIVE OFFICER

     In March 2000, in connection with Hus Tigli's purchase of 6,300,000 shares

semi-annually. Principal and interest on the note become due and payable on

     All future transactions, including any loans from our company to our

                             PRINCIPAL STOCKHOLDERS

     The following table sets forth information known to us with respect to the
beneficial ownership of our common stock as of August 31, 2000, and as adjusted
to reflect the sale of common stock offered in this prospectus:

     - each stockholder known by us to own beneficially more than 5% of our
       common stock, as explained below;

     - each of the Named Executive Officers as listed in the "Summary
       Compensation Table";

     - executive officers who joined us after December 31, 1999;

     - each of our directors; and

     - all of our directors and executive officers as a group.

     Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. In computing the number of shares
beneficially owned by a person and the percentage ownership of that person,
shares of common stock subject to options or warrants held by that person that
are currently exercisable or will become exercisable within 60 days after August
31, 2000, are deemed outstanding, while the shares are not deemed outstanding
for purposes of computing percentage ownership of any other person. Unless
otherwise indicated in the footnotes below, the persons and entities named in
the table have sole voting or investment power with respect to all shares
beneficially owned, subject to community property laws where applicable.

     The percentage of shares beneficially owned is based on the aggregate of
94,348,599 shares of common stock outstanding as of August 31, 2000, assuming
conversion of all outstanding shares of preferred stock into common stock, and
          shares of common stock issued in this offering. Unless otherwise
indicated, the address of each listed stockholder is OMM, Inc., 9410 Carroll
Park Drive, San Diego, CA 92121.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     We are authorized to issue 500,000,000 shares of common stock, $0.0001 par
value, and 100,000,000 shares of undesignated preferred stock, $0.0001 par
value. The following description of our capital stock does not purport to be
complete and is subject to and qualified by our certificate of incorporation and
bylaws, which are included as exhibits to the registration statement of which
this prospectus forms a part, and by the provisions of applicable Delaware law.

COMMON STOCK

     As of August 31, 2000, there were 94,348,599 shares of common stock
outstanding that were held of record by approximately 100 stockholders, assuming
the conversion of all shares of preferred stock into common stock.

     The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the board of directors out of funds legally available for that
purpose. See "Dividend Policy." In the event of a liquidation, dissolution or
winding up of OMM, the holders of common stock are entitled to share ratably in
all assets remaining after payment of liabilities, subject to prior distribution
rights of preferred stock, if any, then outstanding. The common stock has no
preemptive or conversion rights or other subscription rights. There are no
redemption or sinking fund provisions applicable to the common stock.

PREFERRED STOCK

     The board of directors has the authority, without action by the
stockholders, to designate and issue preferred stock in one or more series and
to designate the rights, preferences and privileges of each series, any or all
of which may be greater than the rights of the common stock. We cannot state the
actual effect of the issuance of any shares of preferred stock upon the rights
of holders of the common stock until the board of directors determines the
specific rights of the holders of such preferred stock. However, the effects
might include, among other things, restricting dividends on the common stock,
diluting the voting power of the common stock, impairing the liquidation rights
of the common stock and delaying or preventing a change in control of OMM
without further action by the stockholders. Upon the closing of this offering,
no shares of preferred stock will be outstanding. We have no present plans to
issue additional shares of preferred stock.

WARRANTS

     At August 31, 2000, there were warrants outstanding to purchase a total of
1,930,158 shares of common stock, Series C Preferred Stock and Series D
Preferred Stock, as adjusted to reflect the conversion of all shares of
preferred stock to common stock. Concurrent with our initial public offering the
warrants to purchase preferred stock will automatically convert into warrants to
purchase common stock. Additionally, upon our initial public offering, warrants
to purchase 83,901 shares of common stock will expire unless earlier exercised.
Accordingly, warrants to purchase 1,846,257 shares of common stock will remain
outstanding after the completion of this offering. Warrants to purchase 295,479
shares of common stock will expire on April 14, 2004, unless earlier exercised,
and warrants to purchase 945,207 shares of common stock will expire on the later
of April 4, 2006 or three years after the date of this prospectus, unless
earlier exercised and warrants to purchase 605,571 shares of common stock will
expire on April 6, 2010, unless earlier exercised.

REGISTRATION RIGHTS

     Pursuant to a registration and information rights agreement entered into
between us and holders of 70,751,886 shares of common stock issuable upon
conversion of our preferred stock, we are obligated, under limited circumstances
and subject to specified conditions and limitations, to use our best efforts to
register the registrable shares.

     We must use our best efforts to register shares of the registrable shares:

     - if we receive, with respect to the first registration, the written notice
       from holders of 50% or more of the registrable shares or with respect to
       the second registration, written notice from the holders of 25% or more
       of the registrable shares, requesting that we effect a registration with
       respect to not less than the number of registrable shares then held by
       the holders requesting registration, that would be reasonably anticipated
       to result in a price to the public that will exceed $7,500,000;

     - if we decide to register our own securities, except in connection with
       this offering; or

     - if we receive written notice from holders of the registrable shares
       requesting that we effect a registration on Form S-3, with respect to
       shares of the registrable shares, the reasonably anticipated price to the
       public of which exceeds $500,000 and we are then eligible to use Form
       S-3, which at the earliest will occur twelve calendar months after the
       closing of this offering.

     However, in addition to certain other conditions and limitations, if
requested to register shares of registrable shares, we can delay registration
not more than once in any 12-month period and for not more than 90 days. In
addition, we are obligated to effect only two registrations requested by the
holders of the registrable shares and an additional six registrations on Form
S-3. In any case where we decide to register our own securities pursuant to an
underwritten offering, the managing underwriter may exclude the registrable
shares from the registration.

     These registration rights terminate with respect to each registrable share
upon the first to occur of when the holder can transfer his or her registrable
shares pursuant to Rule 144 or five years after the closing of this offering. In
addition, all holders of these registration rights have entered into lock-up
agreements that waive their registration rights until 180 days following the
date of this prospectus.

DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS

     Certain provisions of Delaware law and our certificate of incorporation and
bylaws could make it more difficult to acquire us by means of a tender offer, a
proxy contest or otherwise, and the removal of incumbent officers and directors.
These provisions, summarized below, are expected to discourage certain types of
coercive takeover practices and inadequate takeover bids and to encourage
persons seeking to acquire control of us to first negotiate with us. We believe
that the benefits of increased protection of our potential ability to negotiate
with the proponent of an unfriendly or unsolicited proposal to acquire or
restructure us outweigh the disadvantages of discouraging takeover or
acquisition proposals because, among other things, negotiation of these
proposals could result in an improvement of their terms.

     We are subject to Section 203 of the Delaware General Corporation Law, an
anti-takeover law. In general, Section 203 prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years following the date the person became an
interested stockholder, unless (with certain exceptions) the "business
combination" or the transaction in which the person became an interested
stockholder is approved in a prescribed manner. Generally, a "business
combination" includes a merger, asset or stock sale, or other transaction
resulting in a financial benefit to the interested stockholder. Generally, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years prior to the determination of interested
stockholder status, did own, 15% or more of a corporation's voting stock. The
existence of this provision would be expected to have an, anti-takeover effect
with respect to transactions not approved in advance by the board of directors,
including discouraging attempts that might result in a premium over the market
price for the shares of common stock held by stockholders.

                                       58
<PAGE>   64

     Our certificate of incorporation and bylaws require that any action
required or permitted to be taken by our stockholders must be effected at a duly
called annual or special meeting of the stockholders and may not be effected by
a consent in writing. In addition, special meetings of our stockholders may be
called only by the board of directors or certain of our officers. Our
certificate of incorporation and bylaws also provide that, beginning upon the
closing of this offering, our board of directors will be divided into three
classes, with each class serving staggered three-year terms, and that certain
amendments of the certificate of incorporation and of the bylaws require the
approval of holders of at least 66 2/3% of the voting power of all outstanding
stock. These provisions may have the effect of deterring hostile takeovers or
delaying changes in control or management of OMM.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is Wells Fargo
Shareowner Services.

NATIONAL MARKET LISTING

     We have applied to list our common stock on The Nasdaq Stock Market's
National Market under the symbol "OMMI."

                        SHARES ELIGIBLE FOR FUTURE SALE

     Immediately prior to this offering, there was no public market for our
common stock. Future sales of substantial amounts of common stock in the public
market could adversely affect the market price of the common stock.

     Upon completion of this offering, we will have outstanding
               shares of common stock, assuming the issuance of
shares of common stock offered by us and no exercise of options after
               , and assuming no exercise of the underwriters' over-allotment
option. All of the                shares sold in this offering will be freely
tradable without restriction or further registration under the Securities Act;
provided, however, that if shares are purchased by "affiliates" as that term is
defined in Rule 144 under the Securities Act, their sales of shares would be
subject to certain limitations and restrictions that are described below.

     The remaining 94,114,087 shares of common stock held by existing
stockholders were issued and sold by us in reliance on exemptions from the
registration requirements of the Securities Act. Of these shares,
               of such shares will be subject to the restrictions contained in
the lock-up agreements described in "Underwriting" on the effective date of this
offering. On the effective date of this offering, shares not subject to the
lock-up agreements described in "Underwriting" will not be eligible for sale
pursuant to Rule 144(k). In addition, holders of stock options could exercise
such options and, subject to lock-up agreements described in "Underwriting,"
sell certain of the shares issued upon exercise as described below.

</TABLE>

RULE 144

     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year would be entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of:

     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately                shares immediately after this
       offering; or

     - the average weekly trading volume of the common stock on the Nasdaq
       National Market during the four calendar weeks preceding the filing of a
       notice on Form 144 with respect to such sale.

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

RULE 144(k)

     Under Rule 144(k), a person who is not deemed to have been one of our
"affiliates" at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an "affiliate," is
entitled to sell such shares without complying with the manner of sale, notice
filing, volume limitation or notice provisions

                                       60
<PAGE>   66

of Rule 144. Therefore, unless otherwise restricted, "144(k) shares" may be sold
immediately upon the completion of this offering.

RULE 701

     In general, any of our employees, directors, officers, consultants or
advisors who purchases shares from us in reliance on Rule 701 in connection with
a compensatory stock or option plan or other written agreement before the
effective date of this offering is entitled to resell such shares 90 days after
the effective date of this offering in reliance on Rule 144, without having to
comply with certain restrictions, including the holding period, contained in
Rule 144.

     The SEC has indicated that Rule 701 will apply to typical stock options
granted by an issuer before it becomes subject to the reporting requirements of
the Securities Exchange Act of 1934, along with the shares acquired upon
exercise of such options (including exercises after the date of this
prospectus). Securities issued in reliance on Rule 701 are restricted securities
and, subject to the contractual restrictions described above, beginning 90 days
after the date of this prospectus, may be sold by persons other than
"affiliates," as defined in Rule 144, subject only to the manner of sale
provisions of Rule 144 and by "affiliates" under Rule 144 without compliance
with its one year minimum holding period requirement.

STOCK OPTIONS

     As of August 31, 2000, there were a total of 13,740,933 shares of common
stock subject to outstanding options under our 1997 Stock Plan, 2,041,787 of
which were vested, and all of which are subject to the lock-up agreements
described in "Underwriting." Immediately after the completion of the offering,
we intend to file registration statements on Form S-8 under the Securities Act
to register all of the shares of common stock issued or reserved for future
issuance under our 1997 Stock Plan, as amended, and our 2000 Stock Purchase
Plan. On the date 180 days after the effective date of the offering, a total of
               shares of common stock subject to outstanding options will be
vested. After the effective dates of the registration statements on Form S-8,
shares purchased upon exercise of options granted pursuant to the 1997 Stock
Plan, as amended, 2000 Stock Purchase Plan and would be available for resale in
the public market, subject to the lock-up agreements described in Underwriting.

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

     The following general discussion summarizes some of the material United
States Federal income and estate tax consequences of the ownership and
disposition of our common stock by a non-U.S. holder of common stock. A
"non-U.S. holder" generally is a holder of common stock that is not, for United
States Federal income tax purposes, any of the following:

     - a citizen or resident of the United States;

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

     - an estate, the income of which is subject to U.S. Federal income taxation
       regardless of its source; or

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

     If you are an individual, you may, in many cases, be deemed to be a
resident alien, as opposed to a nonresident alien, by virtue of being present in
the United States for at least 31 days in the calendar year and for an aggregate
of at least 183 days during a three-year period ending in the current calendar
year (counting for such purposes all of the days present in the current year,
one-third of the days present in the immediately preceding year, and one-sixth
of the days present in the second preceding year). A resident alien is subject
to United States Federal income tax as if such individual was a citizen of the
United States.

     If a partnership is a beneficial owner of our common stock, the tax
treatment of a partner will generally depend upon the status of the partner and
upon the activities of the partnership. If you are a partner of a partnership
holding common stock, you should consult your tax advisor about the U.S. tax
consequences of holding and disposing of shares of our common stock.

     This discussion is limited to non-U.S. holders who hold the common stock as
a capital asset. This discussion does not consider all aspects of U.S. Federal
income and estate taxation or the specific facts and circumstances that may be
relevant to particular non-U.S. holders in light of their personal
circumstances, such as insurance companies, tax-exempt organizations, financial
institutions, broker-dealers or certain U.S. expatriates, and does not address
the treatment of those holders under the laws of any state, local or foreign
taxing jurisdiction. In addition, this discussion does not address any special
tax provisions which may apply to you if you relinquished United States
citizenship or residence. Further, the discussion is based on provisions of the
United States Internal Revenue Code of 1986, as amended, or the "Code," Treasury
regulations under the Code, and administrative and judicial interpretations of
the Code. This discussion is based on the provisions of the Code as they are in
effect on the date of this prospectus. All of these provisions are subject to
change or different interpretation on a possibly retroactive basis.

     EACH PROSPECTIVE HOLDER IS URGED TO CONSULT ITS TAX ADVISOR WITH RESPECT TO
THE UNITED STATES FEDERAL INCOME AND ESTATE TAX CONSEQUENCES OF ACQUIRING,
HOLDING AND DISPOSING OF COMMON STOCK, AS WELL AS ANY TAX CONSEQUENCES THAT MAY
ARISE UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION.

Dividends

     Dividends paid to a non-U.S. holder of common stock generally will be
subject to United States Federal withholding tax at a 30% rate or a lower rate
as may be specified by an applicable income tax treaty. Dividends that are
effectively connected with the non-U.S. holder's conduct of a trade or business
within the United States (and if an income tax treaty applies, are attributable
to a United States permanent establishment of such non-U.S. holder) will not be
subject to withholding tax provided that such non-U.S. holder complies with
applicable certification and disclosure requirements. Instead, the "effectively
connected" dividends will be subject to U.S. Federal income tax on a net basis
at applicable
                                       62
<PAGE>   68

graduated rates in the same manner as dividends paid to United States citizens,
resident aliens and domestic United States corporations. Any effectively
connected dividends received by a corporate non-U.S. holder may also, under
certain circumstances, be subject to an additional "branch profits tax" at a 30%
rate or a lower rate as may be specified by an applicable income tax treaty.

     Under currently effective United States Treasury regulations, dividends
paid prior to January 1, 2001 to an address in a foreign country are presumed to
be paid to a resident of that country, unless the payor has knowledge to the
contrary, for purposes of the withholding discussed above and for purposes of
determining the applicability of a tax treaty rate. Under recently finalized
United States Treasury regulations that will generally be effective for
distributions after December 31, 2000, or the "Final Withholding Regulations,"
however, a non-U.S. holder of common stock who wishes to claim the benefit of an
applicable treaty rate would be required to satisfy applicable certification
requirements. In addition, under the Final Withholding Regulations, in the case
of common stock held by a foreign partnership, (1) the certification
requirements would generally be applied to the partners of the partnership and
(2) the partnership would be required to provide certain information, including
a United States taxpayer identification number. The Final Withholding
Regulations provide look-through rules for tiered partnerships.

     The foregoing rules apply to distributions to shareholders out of our
current or accumulated earnings and profits. Different withholding rules will
apply to any distributions that we pay in excess of our current or accumulated
earnings and profits.

     A non-U.S. holder of common stock that is eligible for a reduced rate of
United States withholding tax under a tax treaty may obtain a refund of any
excess amounts currently withheld by filing an appropriate claim for refund with
the United States Internal Revenue Service.

Gain On Disposition Of Common Stock

     A non-U.S. holder generally will not be subject to United States Federal
income tax for gain recognized on a sale or other disposition of common stock
unless one of the following conditions is satisfied:

     - the gain is effectively connected with a trade or business conducted by
       the non-U.S. holder in the United States (and, if an income tax treaty
       applies, is attributable to a permanent establishment maintained in the
       United States by such non-U.S. holder). The non-U.S. holder will, unless
       an applicable treaty provides otherwise, be taxed on its net gain derived
       from the sale or other disposition under regular graduated U.S. Federal
       income tax rates. Effectively connected gains realized by a corporate
       non-U.S. holder may also, under certain circumstances, be subject to an
       additional "branch profits tax" at a 30% rate or a lower rate as may be
       specified by an applicable income tax treaty;

     - in the case of a non-U.S. holder who is an individual and holds the
       common stock as a capital asset, the holder is present in the United
       States for 183 or more days in the taxable year of the sale or other
       disposition and certain other conditions exist;

     - we are or have been a "United States real property holding corporation"
       for U.S. Federal income tax purposes within the shorter of the five-year
       period preceding such disposition or such non-U.S. holder's holding
       period. We believe that we are not currently, and are not likely to
       become, a "United States real property holding corporation" for U.S.
       Federal income tax purposes. If we were to become a "United States real
       property holding corporation," under currently effective United States
       Treasury regulations, any gain recognized by a non-U.S. holder still
       would not be subject to U.S. Federal income tax if the shares were
       considered to be "regularly traded on an established securities market,"
       and the non-U.S. holder did not hold, directly or indirectly at any time
       during the shorter of the periods described above, more than 5% of our
       common stock; or

     - the non-U.S. holder is subject to tax under certain provisions of the
       Code applicable to U.S. expatriates.

Federal Estate Tax Consequences

     Common stock held by an individual non-U.S. holder at the time of death
will be included in such holder's gross estate for U.S. Federal estate tax
purposes, and may be subject to U.S. Federal estate tax, unless an applicable
estate tax treaty provides otherwise.

Information Reporting and Backup Withholding

     We must report annually to the United States Internal Revenue Service and
to each non-U.S. holder the amount of dividends paid to, and the tax withheld
with respect to, such holder, regardless of whether any tax was actually
withheld. This information may also be made available to the tax authorities in
the non-U.S. holder's country of residence. Under current law, United States
information reporting requirements, other than reporting of dividend payments
for purposes of the withholding tax noted above, and backup withholding tax
generally will not apply to dividends paid to non-U.S. holders that are either
subject to the 30% withholding discussed above or that are not subject to
withholding because an applicable tax treaty reduces or eliminates the
withholding. Otherwise, backup withholding of United States Federal income tax
at a rate of 31% may apply to dividends paid with respect to common stock to
holders that are not "exempt recipients" and that fail to provide certain
information including the holder's United States taxpayer identification number.

     Under current law, generally, unless the payor of dividends has actual
knowledge that the payee is a United States person, the payor may treat dividend
payments to a payee with a foreign address as exempt from information reporting
and backup withholding. However, under the Final Withholding Regulations,
dividend payments generally will be subject to information reporting and backup
withholding unless applicable certification requirements are satisfied. See the
discussion above with respect to the rules applicable to foreign partnerships
under the Final Withholding Regulations.

     In general, United States information reporting and backup withholding
requirements also will not apply to a payment made outside the United States of
the proceeds of a sale of common stock to or through an office outside the
United States of a non-United States broker. However, United States information
reporting, but not backup withholding, requirements will apply to a payment made
outside the United States of the proceeds of a sale of common stock through an
office outside the United States of a broker that, for United States Federal
Income tax purposes, is a United States person, a "controlled foreign
corporation," or a foreign person that derives 50% or more of its gross income
for certain periods from the conduct of a trade or business in the United
States, or, in the case of payments made after December 31, 2000, a foreign
partnership that at any time during its tax year either is engaged in the
conduct of a trade or business in the United States or has as partners one or
more United States persons that, in the aggregate, hold more than 50% of the
income or capital interest in the partnership, unless the broker has documentary
evidence in its records that the holder or beneficial owner is a non-United
States person or the holder or beneficial owner otherwise establishes an
exemption. Payment of the proceeds of the sale of common stock to or through a
United States office of a broker is currently subject to both United States
backup withholding and information reporting unless the holder certifies its
non-United States status under penalties of perjury or otherwise establishes an
exemption.

     Backup withholding is not an additional tax. Amounts withheld under the
backup withholding rules are generally allowable as a refund or credit against
such non-U.S. holder's Federal income tax liability, if any, provided that the
required information is furnished to the Internal Revenue Service.

                                  UNDERWRITING

     Under the terms and subject to the conditions contained in an underwriting
agreement dated                     , we have agreed to sell to the underwriters
named below, for whom Credit Suisse First Boston Corporation, Chase Securities
Inc., CIBC World Markets Corp. and Dain Rauscher Incorporated are acting as
representatives, the following respective numbers of shares of common stock:

</TABLE>

     The underwriting agreement provides that the underwriters are obligated to
purchase all the shares of common stock in the offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults the
purchase commitments of non-defaulting underwriters may be increased or the
offering of common stock may be terminated.

     We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to                     additional shares at the initial public
offering price less the underwriting discounts and commissions. The option may
be exercised only to cover any over-allotments of common stock.

     The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a selling concession of $     per share. The
underwriters and selling group members may allow a discount of $     per share
on sales to other broker or dealers. After the initial public offering, the
public offering price and concession and discount to broker or dealers may be
changed by the representatives.

     The following table summarizes the compensation and estimated expenses we
will pay.

</TABLE>

     The representatives have informed us that the underwriters do not expect
discretionary sales to exceed 5% of the shares of common stock being offered.

     We have agreed that we will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, or file with the Securities and
Exchange Commission a registration statement under the Securities Act of 1933
relating to, any shares of our common stock or securities convertible into or
exchangeable or exercisable for any shares of our common stock, or publicly
disclose the intention to make any offer, sale, pledge, disposition or filing,
without the prior written consent of Credit Suisse First Boston Corporation for
a period of 180 days after the date of this prospectus, except issuances
pursuant to the exercise of employee stock options outstanding on the date
hereof.

     Our officers, directors and holders of at least seven million shares have
agreed that they will not offer, sell, contract to sell, pledge or otherwise
dispose of, directly or indirectly, any shares of our common stock or securities
convertible into or exchangeable or exercisable for any shares of our common
stock, enter into a transaction which would have the same effect, or enter into
any swap, hedge or other arrangement that transfers, in whole or in part, any of
the economic consequences of ownership of our common stock, whether any of these
transactions are to be settled by delivery of our common stock or other
securities, in

                                       65
<PAGE>   71

cash or otherwise, or publicly disclose the intention to make any offer, sale,
pledge or disposition, or to enter into any of these types of transactions,
swap, hedge or other arrangement, without, in each case, the prior written
consent of Credit Suisse First Boston Corporation for a period of 180 days after
the date of this prospectus. If the reported last sale price of our common stock
on the Nasdaq National Market is at least twice the offering price per share for
20 of the 30 trading days ending on the last trading day preceding the 90th day
after the date of this prospectus, then 25% of the shares of our common stock
owned by the officers, directors and stockholders described above subject to the
180-day restriction described above, or                shares, will be released
on the 91st day after the date of this prospectus.

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

     We have agreed to indemnify the underwriters against liabilities under the
Securities Act, or contribute to payments which the underwriters may be required
to make in that respect.

     We have applied to list the shares of common stock on The Nasdaq Stock
Market's National Market under the symbol "OMMI".

     In connection with the offering the underwriters may engage in stabilizing
transactions, over-allotment transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Securities Exchange Act
of 1934.

     - Stabilizing transactions permit bids to purchase the underlying security
       so long as the stabilizing bids do not exceed a specified maximum.

     - Over-allotment involves sales by the underwriters of shares in excess of
       the number of shares the underwriters are obligated to purchase, which
       creates a syndicate short position. The short position may be either a
       covered short position or a naked short position. In a covered short
       position, the number of shares over-allotted by the underwriters is not
       greater than the number of shares that they may purchase in the
       over-allotment option. In a naked short position, the number of shares
       involved is greater than the number of shares in the over-allotment
       option. The underwriters may close out any short position by either
       exercising their over-allotment option and/or purchasing shares in the
       open market.

     - Syndicate covering transactions involve purchases of the common stock in
       the open market after the distribution has been completed in order to
       cover syndicate short positions. In determining the source of shares to
       close out the short position, the underwriters will consider, among other
       things, the price of shares available for purchase in the open market as
       compared to the price at which they may purchase shares through the
       over-allotment option. If the underwriters sell more shares than could be
       covered by the over-allotment option -- a naked short position -- that
       position can only be closed out by buying shares in the open market. A
       naked short position is more likely to be created if the underwriters are
       concerned that there may be downward pressure on the price of the shares
       in the open market after pricing that could adversely affect investors
       who purchase in the offering.

     - Penalty bids permit the representatives to reclaim a selling concession
       from a syndicate member when the common stock originally sold by the
       syndicate member is purchased in a stabilizing or syndicate covering
       transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids
may have the effect of raising or maintaining the market price of the common
stock or preventing or retarding a decline in the market price of the common
stock. As a result the price of the common stock may be higher than the

                                       66
<PAGE>   72

price that might otherwise exist in the open market. These transactions may be
effected on The Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

     A prospectus in electronic format will be made available on the web sites
maintained by one or more of the underwriters participating in this offering.
The representatives may agree to allocate a number of shares to underwriters for
sale to their online brokerage account holders. Internet distributions will be
allocated by the underwriters that will make internet distributions on the same
basis as other allocations.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are made. Any resale of the common stock in Canada must
be made under applicable securities laws which will vary depending on the
relevant jurisdiction, and which may require resales to be made under available
statutory exemptions or under a discretionary exemption granted by the
applicable Canadian securities regulatory authority. Purchasers are advised to
seek legal advice prior to any resale of the common stock.

REPRESENTATIONS OF PURCHASERS

     By purchasing common stock in Canada and accepting purchase confirmation a
purchaser is representing to us and the dealer from whom the purchase
confirmation is received that:

     - the purchaser is entitled under applicable provincial securities laws to
       purchase the common stock without the benefit of a prospectus qualified
       under those securities laws,

     - where required by law, the purchaser is purchasing as principal and not
       as agent, and

     - the purchaser has reviewed the text above under "Resale Restrictions".

RIGHTS OF ACTION (ONTARIO PURCHASERS)

     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

ENFORCEMENT OF LEGAL RIGHTS

     All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Canadian purchasers to effect service of process within Canada upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against the issuer or such persons in Canada
or to enforce a judgment obtained in Canadian courts against such issuer or
persons outside of Canada.

NOTICE TO BRITISH COLUMBIA RESIDENTS

     A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by the purchaser pursuant to this offering. The report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from us. Only one report must
be filed for common stock acquired on the same date and under the same
prospectus exemption.

TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and about the eligibility of the common
stock for investment by the purchaser under relevant Canadian legislation.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of OMM, Inc.

     In our opinion, the accompanying balance sheets and the related statements
of operations, of redeemable convertible preferred stock and stockholders'
equity (deficit) and of cash flows present fairly, in all material respects, the
financial position of OMM, Inc. at December 31, 1998 and 1999, and the results
of its operations and its cash flows for the period from June 30, 1997
(inception) through December 31, 1997 and for the years ended December 31, 1998
and 1999 in conformity with accounting principles generally accepted in the
United States of America. 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 auditing standards generally accepted in the
United States of America, 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 FINANCIAL STATEMENTS

 1. THE COMPANY

     OMM, Inc. (the "Company") was originally incorporated in California on June
30, 1997. In March 2000, the Company reincorporated in the State of Delaware.

     The Company designs, manufactures and sells a family of highly scalable,
all-optical, or photonic, switching subsystems. The Company's products are based
upon its proprietary implementation of micro-electromechanical systems, or MEMS,
which enable all optical switching of data streams. The Company's products allow
optical network systems manufacturers to build scalable, cost-effective systems
that address next generation switching needs in the long haul, metropolitan and
access segments of communication networks.

     Although the Company has begun the production and shipment of its products
to customers, it is devoting significant efforts toward product research and
development. As such, it is subject to a number of risks and challenges similar
to other companies in a similar stage of development. These risks include, but
are not limited to, dependence on a few customers, dependence on key
individuals, dependence on key suppliers of integral components, the need to
develop and market commercially usable products, the ability to obtain adequate
financing to support growth and product development and competition from
substitute products and larger companies with greater financial, technical,
management, and marketing resources.

     The Company incurred net losses of $53,675, $1,249,037 and $7,358,366 for
the period from June 30, 1997 (inception) to December 31, 1997 and for the years
ended December 31, 1998 and 1999, respectively. At December 31, 1999, the
Company had an accumulated deficit of $8,661,078 and has funded those losses
through the sale of redeemable convertible preferred stock and the issuance of
certain long-term obligations. The Company is dependent on the proceeds of
equity financings to meet its future working capital and research and
development needs.

 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Unaudited Pro Forma Stockholders' Equity

     The Company's Board of Directors has authorized the filing of a
Registration Statement with the Securities and Exchange Commission to register
shares of its common stock in an initial public offering ("IPO"). If the IPO is
consummated as presently anticipated, each outstanding share of preferred stock
will automatically convert into three shares of common stock under the terms of
the preferred stock agreements (see Note 4). Unaudited pro forma stockholders'
equity as of June 30, 2000 reflects the conversion of all outstanding preferred
stock into common stock as if such conversion had occurred as of June 30, 2000.

Unaudited Financial Statements

     The interim financial statements as of June 30, 2000 and for the six months
ended June 30, 1999 and 2000 are unaudited and have been prepared on the same
basis as the audited financial statements. In the opinion of management, these
unaudited financial statements reflect all adjustments, consisting only of
normal recurring adjustments, necessary to present fairly the financial
information set forth therein in accordance with accounting principles generally
accepted in the United States of America. Operating results for interim periods
are not necessarily indicative of operating results for an entire year.

Use of Estimates

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make certain estimates and assumptions that affect the reported
amounts of assets and liabilities and the disclosure of contingent assets and
liabilities at the

                                       F-8
<PAGE>   84
                                   OMM, INC.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

financial statement date, as well as the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

Cash and Cash Equivalents

     The Company considers cash equivalents to include highly liquid instruments
with maturities of three months or less from the date of purchase. Cash and cash
equivalents include cash deposited in money market accounts, certificates of
deposit and commercial paper.

Short-Term Investments

     All marketable securities are deemed by management to be available for sale
and are reported at fair value with net unrealized gains or losses reported
within stockholders' equity. Realized gains and losses are recorded based on the
specific identification method. There are no unrealized gains and losses as of
June 30, 2000. Short-term investments consists solely of commercial paper.

Concentrations of Risk

     The Company's financial instruments that are subject to concentrations of
credit risk consist primarily of cash and cash equivalents, short-term
investments and accounts receivable. The Company's policy is to place its cash
and cash equivalents with high quality financial institutions in order to limit
its credit exposure. Short-term investments consist of commercial paper issued
by high credit quality institutions. To date, the Company has not experienced
any credit losses associated with these financial instruments.

     The Company operates in the optical networking industry and primarily sells
its products to optical networking equipment manufacturers. The Company performs
on-going credit evaluations of its customers' financial condition and generally
requires no collateral from these customers. The Company reviews customer
balances for potential credit losses and establishes an allowance for
potentially uncollectible accounts receivable. As of June 30, 2000, the Company
has not identified any potential credit losses and therefore has not established
an allowance for doubtful accounts.

     During the six months ended June 30, 2000, sales to four customers
accounted for approximately 76% of total revenue. Accounts receivable from these
customers as of June 30, 2000 represented approximately 64% of total accounts
receivable.

     Certain key components used in the Company's products are procured from
single or limited source suppliers. The failure of a supplier to deliver on
schedule could delay or interrupt the Company's delivery of products and thereby
adversely affect the Company's revenues and operating results.

Fair Value of Financial Instruments

     The carrying amounts of the Company's short-term investments, accounts
receivable, accounts payable and accrued expenses approximate their fair value
due to the short-term nature of these balances.

Inventory

     Inventory is stated at the lower of cost determined using the first-in,
first-out method or market.

Property and Equipment

     Property and equipment is recorded at cost and is depreciated using the
straight-line method over the estimated useful lives of the assets ranging from
three to five years for laboratory equipment, computer equipment and furniture
and fixtures. Leasehold improvements are amortized using the straight-line
method over the shorter of their estimated useful lives or the term of the
lease. Expenditures for

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

maintenance and repairs are charged to operations as incurred. When assets are
retired or sold, the assets and accumulated depreciation are removed from the
respective accounts and any gain or loss is recognized.

Long-Lived Assets

     Long-lived assets held and used by the Company are reviewed for impairment
whenever events or changes in circumstances indicate that their net book value
may not be recoverable. An impairment loss is recognized if the sum of the
expected future cash flows (undiscounted and before interest) from the use of
the assets is less than the net book value of the asset. The amount of the
impairment loss, if any, will generally be measured as the difference between
the net book value of the assets and their estimated fair values. The Company
has not incurred any such losses.

Intangible Assets

     The Company values its patents based on the actual legal costs incurred to
obtain the patent. Patent costs are amortized using the straight-line method
over the estimated useful life of the patent once the patent is issued. At
December 31, 1999 and June 30, 2000, the Company has capitalized patent costs
totaling $67,877 and $113,829, respectively, of which none was amortized.

Revenue Recognition

     Revenues from product sales are recognized when all of the following
conditions are met: the product has been shipped, the Company has the right to
invoice the customer at a fixed price, the collection of the receivable is
probable and there are no significant obligations remaining. The Company's
products are not subject to any customer acceptance process. Subsequent to the
sale of the products, the Company has no obligation to provide any modification
or customization, upgrades, enhancements or any postcontract customer support.

Research and Development

     Research and development costs are expensed as incurred.

Stock-Based Compensation

     The Company measures compensation expense for its employee stock-based
compensation plan using the intrinsic value method and provides pro forma
disclosures of net loss as if a fair value-based method had been applied in
measuring compensation expense. Accordingly, compensation cost for stock awards
is measured as the excess, if any, of the fair value for financial reporting
purposes of the Company's common stock at the date of grant over the amount an
employee must pay to acquire the stock. Compensation cost is amortized over the
related vesting periods using an accelerated graded method in accordance with
Financial Accounting Standards Board Interpretation No. 28 ("FIN 28"),
"Accounting for Stock Appreciation Rights and Other Variable Stock Option or
Award Plans". Accrued compensation costs for unvested awards that are forfeited
are reversed against compensation expense or unearned stock-based compensation,
as appropriate, in the period of forfeiture. Stock-based awards issued to
non-employees are accounted for using a fair value method and are remeasured to
fair value, as determined by management, at each period end until the earlier of
the date that performance by the counterparty is complete or a performance
commitment has been obtained.

Income Taxes

     Current income tax expense or benefit is the amount of income taxes
expected to be payable or refundable for the current year. A deferred income tax
asset or liability is computed for the expected

                                      F-10

future impact of differences between the financial reporting and tax bases of
assets and liabilities and for the expected future tax benefit to be derived
from tax credits and loss carryforwards. Deferred tax assets are reduced by a
valuation allowance when, in the opinion of management, it is more likely than
not that some portion or all of the deferred tax assets will not be realized.

Comprehensive Income (Loss)

     Comprehensive loss for all periods presented consists solely of net loss.

New Accounting Pronouncements

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements." The objective of SAB 101 is to provide further guidance on revenue
recognition issues in the absence of authoritative literature addressing a
specific arrangement or a specific industry. The guidance in SAB 101 is required
to be followed no later than the fourth fiscal quarter of the fiscal year
beginning after December 15, 1999. The Company has adopted SAB 101 for all
periods presented.

     In March 2000, the Financial Accounting Standards Board ("FASB") issued
FASB Interpretation No. 44 ("FIN 44"), "Accounting for Certain Transactions
Involving Stock Compensation." The Company will be required to adopt FIN 44
effective July 1, 2000 in respect to specific provisions applicable to new
awards, exchanges of awards in a business combination, modifications to
outstanding awards, and changes in grantee status that occur on or after that
date. FIN 44 addresses practice issues related to the application of Accounting
Practice Bulletin Opinion No. 25, "Accounting for Stock Issued to Employees."
The Company believes that the application of FIN 44 will not have a material
impact on the Company's financial position or results of operations.

     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133 ("FAS 133"), "Accounting for Derivative Instruments and Hedging
Activities." In May 1999, the FASB delayed the effective date of FAS 133 by one
year. The Company will be required to adopt FAS 133 for fiscal year 2001. This
statement establishes a new model for accounting for derivatives and hedging
activities. Under FAS 133, all derivatives must be recognized as assets and
liabilities and measured at fair value. The Company believes that the adoption
of this new accounting standard will not have a material impact on the Company's
financial position or results of operations.

Earnings (Loss) per Common Share

     Basic earnings (loss) per share is computed by dividing income (loss)
available to common stockholders by the weighted average number of common shares
outstanding for the period. Weighted average shares exclude shares of unvested
restricted common stock subject to repurchase rights by the Company. Diluted
earnings (loss) per share is computed by dividing income (loss) available to
common stockholders by the weighted average number of common shares outstanding
during the period increased to include dilutive potential common shares that
were outstanding during the period. The dilutive effect of outstanding stock
options, warrants and restricted stock is reflected in diluted earnings per
share by application of the treasury stock method.

     The Company has excluded all redeemable convertible preferred stock,
outstanding stock options, outstanding warrants and unvested restricted common
stock subject to repurchase from the calculation of diluted loss per share for
all periods presented because such securities are antidilutive for these
periods.

 4. COMMON AND REDEEMABLE CONVERTIBLE PREFERRED STOCK

     In October 1998, the Company effected a five-for-one stock split of both
common and preferred stock. The accompanying financial statements and related
notes have been retroactively adjusted to reflect this stock split for all
periods presented.

     In July 2000, the Company's Board of Directors approved a two-for-one
common stock dividend, which had the effect of a three-for-one stock split with
an effective date of August 2, 2000. In accordance with the Series A, B, C, D
and E redeemable convertible preferred stock agreements, the number of common
stock shares into which outstanding shares of Series A, B, C, D and E redeemable
convertible preferred stock are convertible was adjusted consistent with the
common stock split. This stock split has been retroactively reflected in the
accompanying financial statements and related notes for all periods presented.

Common Stock

     At inception, the Company issued 13,212,000 shares of common stock to the
Founders of the Company. The terms of these shares are such that, in the event
of termination of employment, the

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Company may elect to repurchase the unvested shares at the original purchase
price for a period of 90 days. This restriction lapses as to 25% of the shares
one year from the date of issuance, while the restriction as to the remaining
75% of the shares lapses monthly over the subsequent three year period. At June
30, 2000, 3,303,000 of the Founders' shares remain subject to repurchase by the
Company.

     During the period from June 30, 1997 (inception) to December 31, 1997, the
years ended December 31, 1998 and 1999 and during the six months ended June 30,
2000, the Company issued 225,000, 112,500, 52,500 and 7,096,500 shares of common
stock, respectively. The stock vests over the remaining option vesting period,
and is subject to the same restrictions and repurchase provisions as the
Founders' shares described above. At June 30, 2000, 7,284,721 of these shares,
respectively, remain subject to repurchase by the Company.

Redeemable Convertible Preferred Stock

     The Company's redeemable convertible preferred stock has been classified
outside of stockholders' equity based upon recent accounting guidelines
promulgated by the Securities and Exchange Commission. The preferred stock has a
right to liquidation preferences upon a merger, consolidation or sale of
substantially all of the Company's assets. Solely as a result of these
provisions, the preferred stock is treated as redeemable. See "Liquidation
Preferences" set forth below.

     The rights, preferences and privileges of the Preferred Stock are as
follows:

Dividends

     The holders of shares of the Series A, B, C, D and E preferred stock are
entitled to receive dividends of $0.01, $0.024, $0.0365, $0.124, and $0.861,
respectively, per share per annum (subject to appropriate adjustment in the
event of any stock dividend, stock split, combination or other similar
recapitalization affecting such shares), payable when and as declared by the
Board of Directors of the Company. The right to receive dividends shall be
noncumulative; however the Company shall not declare or pay any distributions on
shares of common stock until the preferred stockholders have received a
distribution at the rate specified above. As of June 30, 2000 no dividends have
been declared or paid. Certain lease lines and credit agreements prohibit the
payment of dividends without the creditor's prior approval.

Liquidation Preference

     In certain events, including liquidation, dissolution or winding up of the
Company, including a consolidation or merger and conveyance of substantially all
of the assets of the Company, the holders of Series A, B, C, D and E preferred
stock have a preference in liquidation over the common stockholders of $0.20,
$0.468, $0.73, $2.477 and $17.22 per share, respectively (subject to appropriate
adjustment in the event of any stock dividend, stock split, combination or other
similar recapitalization affecting such shares), plus any dividends declared but
unpaid thereon. If the assets of the Company are not sufficient to fulfill the
liquidation amount, the shareholders will share in the distribution of the
assets on a pro rata basis based on the liquidation amount. These liquidation
preferences terminate upon conversion of shares of the preferred stock into
shares of the common stock upon completion of the IPO.

Voting Rights

     Each holder of preferred stock shall be entitled to the number of votes

Conversion

     Each share of preferred stock is convertible at any time at the option of
the holder into three shares of common stock, subject to customary adjustments
to protect against dilution. In addition, the preferred stock automatically
converts into common stock upon (i) the closing of a public offering of the
Company's common stock at a price of at least $11.48 per share, which will
result in gross proceeds of at least $10,000,000 or (ii) the affirmative vote of
the holders of a majority of the shares of preferred stock outstanding at the
time of such vote. The Company has reserved sufficient shares of common stock
for the conversion of its preferred stock.

 5. STOCK OPTIONS

     The Company established the 1997 Stock Plan (the "Plan"), as amended, under
which 25,050,000 shares of the Company's common stock may be issued pursuant to
the grant of incentive and nonstatutory stock options. Incentive stock options
may be granted to employees only, while nonstatutory stock options and stock
purchase rights may be granted to employees, directors and consultants to the
Company. The Plan is administered by the Board of Directors. Incentive stock
options may be granted at a price per share not less than the value of the
Company's common stock at the date of grant as determined by the Board of
Directors, while nonstatutory options may be granted at a price per share not
less than 85% of the value of the Company's common stock at the date of grant.
The options vest and become exercisable over periods determined by the Board of
Directors. Options generally vest over four years and expire ten years from the
date of grant. At June 30, 2000, there were 2,703,751 shares of the Company's
common stock available for future grant under the Plan.

     In 2000, the Company amended the stock option agreements of certain
employees to allow for early exercise of options to purchase restricted stock
and provide a right of repurchase for the Company.

     The following table summarizes stock option activity under the Plan since
the Company's inception:

     In connection with the grant of stock options, the Company recorded
unearned stock-based compensation, within stockholders' equity of $1,914,312
during the year ended December 31, 1999 and $708,131 and $42,088,705 during the
six months ended June 30, 1999 and 2000, respectively. These transactions have
been recorded as a charge to unearned stock-based compensation and a credit to
additional paid-in capital. Amortization of unearned stock-based compensation,
net of any charges reversed during the period for the forfeiture of unvested
awards, was $429,772 during the year ended December 31, 1999 and $89,419 and
$6,683,006 during the six months ended June 30, 1999 and 2000, respectively.

Fair Value Disclosures

     Had compensation cost been determined based on the fair value method at the
grant dates for awards under the Plan, the Company's net loss on a pro forma

     The fair value of the options was estimated on the date of grant using the
Black-Scholes option pricing model with the following weighted-average
assumptions:

<TABLE>
<CAPTION>
                                                       PERIOD FROM

Expected dividend yield.............................        0.0%           0.0%       0.0%
</TABLE>

     The volatility of the Company's common stock underlying the options was not
considered because the Company's stock was not publicly traded as of December
31, 1999. For purposes of pro forma disclosures, the estimated fair value of
options is amortized to expense over the options' vesting periods using an
accelerated graded method in accordance with FIN 28.

Non-employee options

     In March 2000, the Company issued 24,000 options to purchase common stock
with an exercise price of $0.33 to non-employees in exchange for continued
services. These options vest over a three year period and expire ten years from
the date of grant. In connection with the issuance of the options, the Company
recorded $59,161 of research and development expense through the six months
ended June 30, 2000. The fair value of the options as of June 30, 2000 was
determined based on the application of the Black-Scholes options pricing model
using the following assumptions: weighted average expected life of ten years,
weighted average risk free interest rate of 5.08%, volatility of 90% and
dividend yield of zero. These options will be remeasured at each period end
until the earlier of (i) all services are performed or (ii) the options are
fully vested.

 6. WARRANTS

     During 1999, the Company issued fully vested, immediately exercisable and
non-forfeitable warrants to purchase 413,562 shares of Series C preferred stock
at an exercise price of $0.73 in connection with capital lease facilities and in
connection with a working capital facility (Note 8). The warrants expire over
periods of five to seven years or three years from the effective date of a
qualified initial public offering of the Company. The fair value of the warrants
at the time of grant, which was determined by management to be $496,158 based
upon the application of the Black-Scholes option pricing model using the
following assumptions: weighted average contractual life of 6 years, weighted
average risk free interest rate of 5.10%, volatility of 90% and expected
dividend yield of zero, was recorded as prepaid financing fees and is being
amortized ratably over the term of the capital lease and working capital
facilities. At June 30, 2000, all of these warrants remain outstanding.

     In July 1999, the Company issued a fully vested, immediately exercisable
and non-forfeitable warrant to purchase 27,967 shares of Series C preferred
stock at an exercise price of $0.73 in connection with services received prior
to the date of grant. This warrant expires at the earlier of (i) five years from
the date of grant; (ii) the closing of an underwritten public offering of the
Company's common stock in which the gross proceeds are not less than $10
million; (iii) upon the closing of a consolidation or merger of the Company with
or into, or the transfer of all or substantially all of the Company's assets, or
at least 50% of the Company's voting stock to another corporation. The fair
value of this warrant at the time of grant, which was determined by management
to be $39,825 based upon application of the Black-Scholes option pricing model
using the following assumptions: contractual life of 5 years, risk free interest
rate of 5.60%,

volatility of 90% and dividend yield of zero, was expensed during 1999. At June
30, 2000, all of these warrants remain outstanding.

     In February 2000, the Company entered into a service agreement with a
consultant whereby, upon the successful completion of each of two assignments,
the Company will grant to the consultant warrants to purchase 36,000 shares of
the Company's common stock at an exercise price of $0.167. The fair value of
these warrants as of June 30, 2000, which was determined by management to be
$364,320 based upon application of the Black-Scholes option pricing model using
the following assumptions: contractual life of 5 years, risk free interest rate
of 6.18%, volatility of 90% and dividend yield of zero, was recorded as
additional general and administrative expense in the accompanying statement of
operations for the six months ended June 30, 2000. These warrants will be
remeasured at each period end until all services have been performed.

     In March 2000, the Company issued fully vested, immediately exercisable and
non-forfeitable warrants to purchase 60,000 shares of common stock at an
exercise price of $0.167 in connection with services from a consultant received
prior to the date of grant. These warrants expire at the earlier of (i) five
years from the date of grant, (ii) the closing of an underwritten public
offering of the Company, which will result in gross proceeds of at least
$10,000,000, or (iii) upon the closing of a consolidation or merger of the
Company with or into, or the transfer of all or substantially all of the
Company's assets, or at least 50% of the Company's voting stock, to another
corporation. The fair value of these warrants at the time of grant, which was
determined by management to be $144,600 based upon application of the Black-
Scholes option pricing model using the following assumptions: contractual life
of 5 years, risk free interest rate of 6.59%, volatility of 90% and dividend
yield of zero, was expensed during the six months ended June 30, 2000. In August
2000 the company issued warrants to purchase 16,000 shares of common stock at a
weighted average exercise price of $2.30 in connection with services received.
These warrants have the same terms stated above. All these warrants were
exercised in August 2000.

     In April 2000, the Company issued fully vested, immediately exercisable and
non-forfeitable warrants to purchase 201,857 shares of Series D preferred stock
at an exercise price of $2.477 in connection with a credit facility to finance
up to $10,000,000 in equipment acquisitions (Note 8). The warrants expire ten
years from the date of grant. The fair value of the warrants at the time of
grant, which was determined by management to be $2,385,950 based upon the
application of the Black-Scholes option pricing model using the following
assumptions: weighted average contractual life of 10 years, weighted average
risk free interest rate of 5.86%, volatility of 90% and expected dividend yield
of zero, was recorded as prepaid financing fees and is being amortized ratably
over the term of the capital lease. At June 30, 2000, all of these warrants
remain outstanding.

</TABLE>

     Based upon the lack of prior earnings history of the Company and based upon
other available evidence, management has recorded a full valuation allowance for
deferred tax assets as it is more likely than not that such assets will not be
realized. Due to the cumulative losses of the Company since inception and as a
result of the full valuation allowance against net deferred tax assets, no
current or deferred income tax provision or benefit was recorded during all the
periods presented.

     A reconciliation of income taxes to the amount computed by applying the
statutory federal income tax rate to the net loss is summarized as follows:

credit carryforwards do not expire.

     During the period from June 30, 1997 (inception) through December 31, 1998,
certain stock ownership changes occurred. As a result, management estimates that
the annual utilization in future years of net operating loss and research and
development credit carryforwards generated through December 31, 1998 will be
limited pursuant to Sections 382 and 383 of the Internal Revenue Code.

     During 1999, the Company obtained capital lease facilities to finance up to
$3,000,000 in property and equipment acquisitions and a $500,000 working capital
facility. During 1999, the Company borrowed $500,000 under the working capital
facility. The working capital facility stipulates an interest rate equal to
prime plus 0.5%, 10% at June 30, 2000. At December 31, 1999, the working capital
facility had been repaid in full.

     During the six months ended June 30, 2000, the Company refinanced, under
capital lease facilities, property and equipment totaling $2,308,720, of which
$927,917 was acquired during 1999 and is included in property and equipment at

restricted cash balance at June 30, 2000. The letter of credit provides for
automatic yearly renewals with annual reductions of $440,000 over the term of
the lease.

 9. BENEFIT PLANS

401(k) Plan

     The Company sponsors an employee savings plan that qualifies as a deferred
salary arrangement under Section 401(k) of the Internal Revenue Code. Under the
savings plan, participating employees may defer a portion of their pre-tax
earnings, up to the Internal Revenue Service annual contribution limit.
Additionally, the Company may elect to make matching contributions into the
savings plan at its sole discretion. As of June 30, 2000, the Company has not
made any matching contributions into the savings plan.

2000 Stock Purchase Plan

     In September 2000, the Board approved the establishment, upon the closing
of an initial public offering of the Company's common stock, of the 2000 Stock
Purchase Plan (the "Purchase Plan"). A total of 4,000,000 shares of the
Company's common stock have been reserved for issuance under the Purchase Plan,
none of which have been issued. The number of shares reserved for issuance under
the Purchase Plan will be subject to an annual increase on January 1 of each
year beginning in 2001 equal to the lesser of (a) 2,700,000 shares, (b) 2.0% of
the outstanding shares on such date or (c) a lesser amount as determined by the
Board. The Purchase Plan permits eligible employees to purchase shares of common
stock at a fifteen percent (15%) discount through payroll deductions during
sequential 6-month offering periods. Unless the Board establishes a higher
price, the price at which shares are purchased under the Purchase Plan for such
offering period is equal to 85% of the lesser of the fair market value of the
common stock on the first day of such offering period or the last day of the
purchase period. The initial offering period will commence on the effective date
of an initial public offering of the Company's common stock.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law, or DGCL, permits
indemnification of officers, directors and other corporate agents under certain
circumstances and subject to certain limitations. Our Certificate of
Incorporation and Bylaws provide that we shall indemnify our directors, officers
and agents to the fullest extent permitted by the DGCL against judgments and
monetary damages as a result of such individual serving as a director, officer
or agent, including in circumstances in which indemnification is otherwise
discretionary under such law. Our Bylaws also provide that we shall advance
expenses incurred by a director, officer or agent in advance of a final
disposition of such action provided we receive an undertaking by such individual
to repay the amounts advanced if it is ultimately determined that he is not
entitled to be indemnified. In addition, with the approval of our board of
directors and our stockholders, we have entered into separate indemnification
agreements with our directors, officers and certain employees that require us,
among other things, to indemnify them to the fullest extent permitted by law
against any judgments, amounts paid in settlement and all expenses incurred in
connection with defending any action that may arise by reason of their status or
service (other than liabilities arising from willful misconduct of a culpable
nature) and to obtain directors' and officers' insurance, if available on
reasonable terms. We are required to advance expenses incurred by a party to
such indemnification agreement in advance of a determination or judgment subject
to a determination by our board of directors or another party who is not a party
or defendants to such claim that the party to the indemnification agreement
would not be permitted to be indemnified under applicable law. Parties to the
indemnification agreements would not be indemnified for any acts, omissions or
transactions for which they are prohibited from receiving indemnification under
applicable law.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

     Since inception, we have issued unregistered securities to a limited number
of persons as described below:

     None of these transactions involved any underwriters, underwriting
discounts or commissions, or any public offering, and we believe that each
transaction was exempt from the registration requirements of the Securities Act
by virtue of Section 4(2) thereof, Regulation D promulgated thereunder or Rule
701 pursuant to compensatory benefit plans and contracts relating to
compensation as provided under 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,

                                      II-1

issued in such transactions. All recipients had adequate access, through their
relationships with us, to information about us.

     FINANCIAL STATEMENT SCHEDULES

     Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the financial
statements or notes thereto.

ITEM 17. UNDERTAKINGS

     The 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 by the registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions referenced in Item 14 of
this registration statement 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

                                      II-4
<PAGE>   104

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 a 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 registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of Prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of Prospectus filed by 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 that time shall be
     deemed to be the initial bona fide offering thereof.
