Item 1. Business

INTRODUCTION

   AltiGen designs, manufactures and markets integrated, multifunction
telecommunications systems that allow businesses to use data networks, such as
the Internet, and the traditional telephone network interchangeably and
seamlessly to carry voice and data communications.

   The Company's principal executive offices are located at 47427 Fremont
Blvd., Fremont, California 94538. The telephone number at that address is (510)
252-9712. The Company was incorporated in May 1994 and reincorporated by merger
in Delaware in June 1999.

BACKGROUND AND GENERAL DEVELOPMENT OF BUSINESS

FISCAL 1999

   Entering fiscal year 1999, AltiGen had three key objectives: to continue and
accelerate the development of its telecommunications systems, to extend and
expand our market position and to prepare for an initial public offering.

   The Company met its first objective by providing a next generation
communications system to allow businesses to use integrated systems that
receive, manipulate and transmit voice communications over the traditional
telephone network, as well as data networks such as the Internet. Our
integrated, multifunction telecommunications systems provide new services to
end users, giving businesses the choice of placing calls over data networks or
traditional phone lines. Net revenues increased 69.7% to $6.6 million in fiscal
1999 from $3.9 million in fiscal 1998.

   The Company met its second objective of extending and expanding our market
position by utilizing advertising and promotional activities to establish
brand-name recognition, increasing training to identify and educate new
qualified authorized dealers and to build a well-developed distribution
channel, promoting customer and end user awareness of the features and benefits
of our products. According to a Frost & Sullivan research report, AltiGen's
market share in the North America Server-Based PBX Market increased from 21% in
1998 to 38% in 1999.

   The Company met its third objective by maintaining a considerable lead
position in product development and marketing, providing high quality service
and technical support, developing sales and distribution capabilities,
maintaining efficiency of manufacturing, and establishing brand-name
recognition. These efforts culminated in the completion of an initial public
offering of our common stock on October 4, 1999.

INDUSTRY BACKGROUND

 The Growth of the Internet

   The Internet is experiencing tremendous growth and is emerging as a global
medium for communications and commerce. Many factors are driving the growth of
the Internet, including:

  . improvements in the design and construction of computer systems and
    networks;

  . the emergence of technologies which facilitate the buying and selling of
    goods and services on the Internet, which is referred to as online
    commerce or e-commerce; and

  . easier, faster and cheaper Internet access through a large and growing
    base of personal computers and other devices.

According to International Data Corporation, or IDC, the number of Internet
users worldwide will grow from 69 million at the end of 1997 to 320 million by
2002. The increasing capabilities and use of the Internet and other networks
such as corporate intranets are significantly influencing telecommunications
today.

 Convergence of Voice and Data

   Traditionally, businesses have supported two separate, incompatible networks
to handle their communications needs. The first has been the traditional
telephone network, which relies on a technology called "circuit-switching." A
circuit-switched network establishes and maintains a dedicated (i.e. not
shared) line between calling parties for the duration of a call. The second
type of network on which businesses have traditionally relied is a data or
"packet-switched" network, such as the Internet. In packet-switched networks,
voice, video, images or data is divided into small packets of signals that are
simultaneously routed over different paths to a final destination where they
are recombined. Packet-switched networks are more efficient than the
traditional telephone network because network paths are not dedicated to a
single user, but instead are available to be shared by all users. In contrast
to a circuit-switched network, network capacity is allocated only during
transmission, and messages can be compressed and stored more efficiently. The
Internet is accelerating the convergence of voice and data to a single
integrated packet-based network that can support both voice and data using
Internet Protocol.

   A growing number of businesses have recognized data networks such as the
Internet as a valuable and economical medium for internal and public
communications. These businesses seek to reduce their telecommunications costs
by moving their voice communications to packet-switched networks, such as
corporate intranets and the Internet. Although packet-switched networks can
offer more efficiency and value to businesses, the traditional telephone
network remains the standard for voice communications today. As a result,
businesses that wish to take advantage of packet-switched networks for voice
communications must nevertheless be able to place and receive calls over the
traditional telephone network with customers, suppliers and others who rely
solely on the traditional telephone network for voice communications.
Consequently, there is a need for one common switching system that can
interface with both packet-switched networks and the traditional telephone
network.

 Evolution Begins in Small- to Medium-Sized Businesses

   Small-to medium-sized businesses of up to 150 employees are likely to be the
first to use converged voice and data networks because, unlike large
organizations, they may not be heavily invested in outdated systems that
continue to be used because the costs of replacing them outweigh their
shortcomings, and can more quickly take advantage of new technological trends.
Most of these businesses today use a traditional private telephone network as
the backbone of their connection to the voice network, and maintain a separate
data network.

   Today's traditional private telephone network remains an expensive,
proprietary solution. These systems require skilled personnel to physically
prepare the installation site and to install the equipment and can be

                                       4
<PAGE>

difficult to install, upgrade and maintain. For example, adding voice mail to a
traditional private telephone network system requires personnel to configure
and connect a separate server to the system. Thus, after adding a number of
features such as voice mail, a traditional private telephone network may be
difficult to maintain because of the diversity of its hardware components, as
well as the number and complexity of connections between those components.
Administering this system thus may become prohibitively expensive for small- to
medium-sized businesses with limited resources.

   In recent years, a new generation of integrated, multifunction
telecommunications systems has emerged to address the challenges and
inadequacies associated with traditional private telephone systems. Frost &
Sullivan estimates that the market for integrated, multifunction
telecommunications systems that rely on general-purpose computers, which it
terms the "server-based PBX systems market" was $41.8 million in 1998 and will
grow to $403.9 million in 2002, representing a compounded annual growth rate of
76.3%. Frost & Sullivan also estimates that the market for integrated,
multifunction telecommunications systems that rely on data networks that use
the same communications format as the Internet, which it refers to as "IP-based
PBX systems" was $31.5 million in 1998 and will grow to $595.1 million in 2002,
representing a compounded annual growth rate of 108.4%.

   Most existing telecommunications systems do not address the needs of
businesses that wish to transmit voice communications over both the traditional
telephone network and data networks. For example, businesses may wish to route
internal calls over their existing voice network and route calls between
offices over data networks, such as the Internet, all using the same
telecommunications system. We believe a significant opportunity exists to
provide small- to medium-sized businesses with an integrated solution that
delivers the benefits of integrated, multifunction telecommunications systems
using the Internet as well as the traditional telephone network.

THE ALTIGEN SOLUTION

   We design, manufacture and market next generation, integrated, multifunction
telecommunications systems that use both data networks, such as the Internet,
and the traditional telephone network to provide new services to end users that
were unavailable with traditional private telephone systems. AltiServ, our
Windows NT-based system, interfaces with the traditional telephone network and
data networks, permitting our customers to take advantage of the converging
communications infrastructure. Our systems integrate voice and data
communications with fewer components than traditional systems and other
multifunction telecommunications systems.

   Key benefits of our solution include:

  . Ability to use both Data Networks, such as the Internet, and the
    Traditional Telephone Network. Our systems provide the benefits of the
    converging communications infrastructure by enabling businesses to route
    voice calls over the Internet and other data networks or the traditional
    telephone network. Our system design integrates seamlessly with both
    types of networks, providing flexibility for businesses to configure
    their telecommunications systems to suit their needs.

  . Lower Telecommunications Costs. By routing voice over data networks,
    including the Internet, our systems eliminate toll charges associated
    with long-distance calls. Using our products, businesses can send and
    receive voice communications over the Internet or existing data lines
    that constitute their intranets.

  . Innovative Features. Our systems provide integrated voice and data
    capability, allowing numerous features previously available only with a
    combination of multiple systems, typically from different vendors.
    AltiGen's AltiServ system has typical call handling and routing
    functions, as well as specialized functions such as Zoomerang, which
    enables users to retrieve a voice mail message, automatically place a
    call to respond and return to the voice mail system to continue reviewing
    messages.

                                       5
<PAGE>

  . Ease of Installation, Use and Maintenance. The configuration of the
    AltiServ system and its use of industry-standard hardware and software
    platforms allows for easy installation and system maintenance. AltiServ
    enables system administrators to manage the voice, voice messaging, e-
    mail and Internet features of our products through a single consistent
    user interface.

  . Reduced Administration Costs. Our user interface allows end users to
    administer their system internally. With traditional private telephone
    systems, businesses frequently require a third-party service provider to
    perform tasks as simple as changing a phone extension or adding a phone
    line. These expenses can be significant for installation, system upgrades
    and modifications. Using AltiServ, system administrators can perform many
    of these tasks and reduce additional expenditures.

PRODUCTS AND CORE TECHNOLOGIES

   We design and develop hardware (circuit boards) and software for integration
by our distributors and dealers into general purpose computer platforms for use
by small- to medium-sized business. AltiGen's AltiServ system is a complete
communications system capable of coordinating different types of
communications, including e-mail and voice mail. The AltiServ system answers
incoming phone calls, transfers calls to individual extensions or to groups of
company representatives and tracks the call activity for future performance
improvements. An auto attendant feature allows incoming callers the opportunity
to select choices in the kind of service they need or to answer calls when no
attendants are available. Our software is designed for easy installation and
maintenance.

   The AltiServ system functions over packet-switched networks including
corporate intranets and the Internet. AltiServ supports combining multiple
forms of communication such as voice mail and data files into a single e-mail
message. The AltiServ system forwards e-mail and voice mail messages over data
networks to other mail service systems. The AltiServ system also provides
remote employees access to their voice mail messages over the Internet.

   The AltiServ system allows a business to connect multiple branch offices
using AltiServ systems such that calls between these locations can be carried
over low-cost data network connections as opposed to the traditional telephone
network.

</TABLE>

 Hardware and Firmware

   AltiGen developed a single base circuit board with powerful digital signal
processing technology. Digital signal processing is a computer built on to the
circuit board which can run special, high-speed software programs, called
firmware. The firmware can receive, send and modify digital information for
communications with network services. AltiGen's basic Triton DSP board can be
used to create different circuit boards to meet many communication requirements
by simply adding a few hardware and/or software components to the basic board.
For example, AltiGen's Triton DSP series circuit board becomes a T1 or ISDN
communication circuit board or a circuit board supporting the same
communication format as the Internet with simple changes in on-board software
and, in some cases, new chips.

   This modular design not only allows AltiGen to provide new capabilities, but
also allows AltiGen's products to achieve a high degree of reliability since
the underlying technology is the same and hence receives our full attention to
any material and processing improvements that can or need to be made.

 Software

   AltiGen's software products are based on modular software components similar
to the concept discussed for our hardware and firmware above. The service
provider layer of software is composed of separate software components, each of
which communicates with a hardware circuit board within the AltiServ system.
The middleware layer interacts with all the service providers in the system and
manages their resources. This layer hides the complexity of the hardware from
application programs wanting to provide specific features. The application
program layer consists of components that implement the application logic such
as voice mail and auto attendant. These applications do not need to know about
the hardware or how to communicate with the hardware.

   The layered architecture of AltiServ provides important benefits:

  . Shorter time is required to develop new features;

  . Development times are more predictable, thus saving money;

  . New hardware and software features can be added easily and rapidly; and

  . Changing one component in the system does not mean that other components
    have to be changed.

MARKETING, SALES AND CUSTOMER SUPPORT

 Marketing

   Our marketing efforts currently focus on increasing demand for our products
in North America, Japan, Europe and Latin America. We work to increase market
awareness of our technology and demand for our products in the small- to
medium-sized business market through cooperative marketing, print, radio and
Web advertising and direct mail campaigns. We have a customer referral program
through which our AltiServ customers can refer potential buyers to us through
our Web site.

                                       7
<PAGE>

   To assist our distributors, dealers, original equipment manufacturers and
strategic partners, we provide market development funds and technical and sales
training developed specifically for our products. In return, these companies
must provide us with point-of-sale reports that allow us to develop a profile
of end users of our systems and evaluate the effectiveness of our marketing
efforts.

   We have recently formed marketing alliances with Hewlett-Packard and Compaq.
Specifically, we have signed a memorandum of understanding with the Covision
Internet Solutions Program of Hewlett-Packard, under which this group will
market our products through its Internet channels. We have signed a Compaq
Solutions Alliance Agreement, under which Compaq will market and bundle our
products to its channel members and to customers. To date we have not
recognized significant revenues as a result of these alliances.

 Sales

   We currently have sales and support staff in: New York, New York; Chicago,
Illinois; Atlanta, Georgia; Dallas, Texas; and Fremont, California. Our network
of distributors and over 400 dealers sell our systems to end users. Our sales
force answers incoming calls from end users and refers new leads to a qualified
dealer near each end user's location.

 Customers

   Our customers are primarily distributors and dealers who sell and resell our
products to end users. We have distribution agreements with Ingram Micro and
Tech Data Corporation in the United States and Kanematsu Semiconductor
Corporation and Nitsuko Corporation abroad. Sales through Ingram Micro and Tech
Data accounted for approximately 3% and 24%, respectively, of our revenues in
fiscal year 1998, and approximately 19% and 27%, respectively, of our revenues
in fiscal 1999. We also have over 400 authorized dealers, who sell our products
directly to end users. We continually seek to identify and authorize new
dealers. We review our dealers quarterly and de-authorize those who do not meet
our standards.

 Customer Support

   We believe that consistent, high-quality service and support are key factors
in attracting and retaining customers. Our customer support group, located in
Fremont, California, coordinates service and technical support of our products
and provides service 24 hours a day, seven days a week. This group assists our
distributors and dealers in resolving installation and support issues that
arise from their sales to end users and also provides limited support to end
users to supplement their dealer support. Customers can also access technical
information and receive technical support through our Web site.

RESEARCH AND DEVELOPMENT

   The market for our products is characterized by rapidly changing technology,
evolving industry standards and frequent product introductions. We believe that
our future success depends in large part upon our ability to continue to
enhance the functionality and uses of our core technology. We intend to extend
the functionality and uses of our hardware and software technology by
continuing to invest in research and development.

   We currently conduct the majority of our product development in-house. We
also use a small number of independent contractors to assist with certain
product development and testing activities. We intend to continue working with
our strategic partners to enhance our products. As of September 30, 1999, we
employed 32 individuals in engineering, research and development and support.

   During fiscal 1999, 1998, and 1997, our research and development expenses
were approximately $3,658,000, $1,927,000, and $1,498,000, respectively.

COMPETITION

   The markets for our products are intensely competitive, continually evolving
and subject to changing technologies. We currently compete with companies
providing traditional telephone systems, principally Lucent

                                       8
<PAGE>

Technologies and Nortel Networks. We also compete against companies providing
multifunction telecommunications systems, including Picazo Communications, Inc.
and Artisoft, Inc. We face potential competition from companies such as
Shoreline Teleworks, Inc., NBX Corporation, acquired by 3Com Corporation,
Selsius Systems, acquired by Cisco Systems, Inc., as well as any number of
future competitors. Many of our competitors are substantially larger than we
are and have significantly greater name recognition, financial, sales and
marketing, technical, customer support, manufacturing and other resources.
These competitors may also have more established distribution channels and
stronger relationships with local, long distance and Internet service
providers. These competitors may be able to respond more rapidly to new or
emerging technologies and changes in customer requirements or devote greater
resources to the development, promotion and sale of their products. These
competitors may enter our existing or future markets with solutions that may be
less expensive, that may provide higher performance or additional features or
that may be introduced earlier than our solutions.

   We believe the principal competitive factors in our market include, or are
likely to include:

  . product performance and features such as the ability to integrate voice
    and data;

  . price;

  . reliability;

  . ease of use;

  . size of customer base;

  . quality of service and technical support;

  . sales and distribution capabilities; and

  . strength of brand name.

   We believe that our principal competitive advantages include:

  . established brand-name recognition;

  . a well-developed and trained distribution channel; and

  . a considerable lead in product development and marketing.

   We cannot be certain that we will be able to compete successfully with
existing or new competitors. If we fail to compete successfully against current
or future competitors, our business could suffer.

SEASONALITY

   Typically, the Server-Based PBX industry experiences some seasonal
variations in demand, with weaker sales in the winter months because of
holidays and customers' planned shutdowns. This seasonality is particularly
evident in the North American market.

INTELLECTUAL PROPERTY

   We generally rely upon patent, copyright, trademark and trade secret laws to
protect and maintain our proprietary rights for our technology and products.
AltiGen is a registered trademark, and Zoomerang is a trademark pending
registration by AltiGen in the United States and other jurisdictions. In
addition, the AltiGen logo is a trademark of AltiGen in the United States and
other jurisdictions.

   We have filed several U.S. patent applications relating to various aspects
of our client and server software, mixed-media communications and computer
telephony. We expect to file patent applications as we deem appropriate to
protect our technology and products. We cannot be sure that our patent
applications will result in

                                       9
<PAGE>

the issuance of patents, or that any issued patents will provide commercially
significant protection to our technology.

   To help protect our intellectual property rights, our employees, consultants
and strategic partners enter into confidentiality agreements that prohibit
disclosure of our proprietary information. We also currently require employees
and consultants to assign to us their ideas, developments, discoveries and
inventions.

   We attempt to avoid infringing known proprietary rights of third parties in
our product and service development efforts. We have not, however, conducted
and do not conduct comprehensive patent searches to determine whether the
technology used in our products infringes patents held by third parties. In
addition, it is difficult to proceed with certainty in a rapidly evolving
technological environment in which there may be numerous patent applications
pending, many of which are confidential when filed, with regard to similar
technologies. If we were to discover that our products violate third-party
proprietary rights, we might not be able to obtain licenses to continue
offering these products without substantial reengineering. Efforts to undertake
this reengineering might not be successful, licenses might be unavailable on
commercially reasonable terms, if at all, and litigation might not be avoided
or settled without substantial expense and damage awards (See Part I, Item 3,
Legal Proceedings).

MANUFACTURING AND ASSEMBLY

   Our manufacturing operations consist of purchasing, receiving, inspecting,
testing, packaging and shipping. We depend on three suppliers who provided us
with about 76% of our hardware product components during 1999. We put these
components into kits and send them to a sub-contractor or external
manufacturing facility for assembly. The final hardware assembly, software
installation and testing of our products is performed in-house at our 11,000
square-foot manufacturing floor, located at our corporate headquarters in
Fremont, California. Our manufacturing and assembly processes enable us to
configure our products to adapt to different customer specifications at the
final assembly stage. This flexibility is designed to reduce both our assembly
cycle time and our need to maintain a large inventory of finished goods. We
believe that the efficiency of our assembly process to date is largely due to
our product architecture and our commitment to assembly process design.

   We test our products both during and after the assembly process using
internally developed product assurance testing procedures, which include
initial visual inspection and functional testing and final systems testing.
Although we generally use standard components for our products and try to
maintain alternative sources of supply, we purchase some key components from
sole-source suppliers for which alternative sources are not currently
available. We incorporate the following sole-sourced components in our
products:

  . A Mitel Corporation chip is included in all of our boards and is
    particularly important because it is the means by which our boards
    communicate with each other to enable our products to function correctly.

  . Texas Instruments Incorporated's digital signal processor ("DSP") chip
    for our Triton family of boards. The DSP chip is designed to perform the
    mathematics, data compression and other tasks that are needed to
    manipulate voice communications that are routed through our products. The
    DSP chip is also used in our Integrated Services Digital Network Basic
    Rate Interface board. This board enables our products to work with
    communications networks that are used in Japan. We expect that sales of
    these boards will represent an increasing percentage of our revenues in
    the future.

  . PMC-Sierra, Inc.'s T1 chip for our Triton T1 board allows our board to
    work with digital communications lines. We expect that sales of our
    Triton T1 board will represent an increasing percentage of our revenues
    in the future.

   Loss of any key component supplier would adversely impact our business.

                                       10

EMPLOYEES

   As of September 30, 1999, we had 85 full-time employees, including 32 in
research and development, 33 in marketing, sales and support, 9 in operations,
and 11 in finance and administration. Our future success will depend, in part,
on our ability to continue to attract, retain and motivate highly qualified
technical, marketing, engineering and management personnel, who are in great
demand.

$325,000. We also conduct research and development in a 2,919 square foot
facility in Shanghai, China, which we lease at an annual rate of approximately
$30,000. We believe that our existing facilities are adequate for our needs
through at least the end of year 2000. We believe that any additional space we
may need in the future will be available on commercially reasonable terms.

                                       12

Item 3. Legal Proceedings

   Generally, litigation, which could be costly and time consuming, may be
necessary to determine the scope and validity of others' proprietary rights, or
to enforce any patent issued to us, in either case, in judicial or
administrative proceedings. For example, we are currently engaged in litigation
with NetPhone, Inc. In June 1999, we received a letter from NetPhone alleging
that we infringe a patent owned by NetPhone. On June 30, 1999, we filed a
request for a declaration from the United States District Court for the
Northern District of California that AltiGen does not infringe any valid claim
of NetPhone's patent. NetPhone answered AltiGen's complaint on July 13, 1999
and asserted a counterclaim against AltiGen alleging that AltiGen infringes the
NetPhone patent and seeking to preliminarily and permanently enjoin AltiGen
from making, importing, using, offering to sell or selling a device under the
name Quantum. On August 11, 1999, NetPhone filed a motion for preliminary
injunction. On September 7, 1999, we filed our Opposition to NetPhone's motion.
NetPhone's Motion has not yet been decided. A hearing was held on NetPhone's
Motion for Preliminary Injuction on December 13, 1999, and the Court has taken
the matter under submission. Based upon advice of our patent prosecution
counsel, we believe that the claims of NetPhone's patent are invalid or not
infringed by our Quantum board product. Accordingly, we intend to continue to
litigate the lawsuit and to contest NetPhone's Motion vigorously, and we do not
believe that the ultimate outcome of this matter will have a material impact on
our business. However, litigation is subject to inherent uncertainties and,
therefore, we cannot assure you that we will prevail in this litigation, or
that an adverse outcome would not adversely affect our business or financial
condition.

   An adverse outcome in the NetPhone litigation or any other litigation could
subject us to significant liabilities to third parties, require us to obtain
licenses from third parties, or require us to cease product sales and possibly
alter the design of our products. Not all licenses to third-party patents or
proprietary rights may be available on acceptable terms. In addition, the laws
of certain countries may not protect our intellectual property.

Item 4. Submission of Matters to a Vote of Security Holders

   Not applicable.

Item 5. Market for Registrant's Common Equity and Related Stockholder Matters

   The effective date of AltiGen's initial public offering was on October 4,
1999. The principal market for Company's common stock is The Nasdaq Stock
Market. On September 30, 1999, AltiGen was a privately-held company.

   As of September 30, 1999, the Company had approximately 160 shareholders of
record. We have never declared or paid any cash dividends on our capital stock.
We currently expect to retain future earnings, if any, to support operations
and to finance the growth and development of our business. Therefore, we do not
expect to pay cash dividends in the foreseeable future.

USE OF PROCEEDS FROM SALES OF REGISTERED SECURITIES

   On October 8, 1999, the Company completed an initial public offering (the
"Offering") of its Common Stock, $.001 par value. The managing underwriters in
the Offering were CIBC World Markets Corp., Dain Rauscher Wessels, a division
of Dain Rauscher Incorporated, and FAC/Equities, a division of First Albany
Corporation (the "Underwriters"). The shares of Common Stock sold in the
Offering were registered under the Securities Act of 1933, as amended, on a
Registration Statement on Form S-1 (the "Registration Statement") (Reg. No.
333-80037) that was declared effective by the SEC on October 4, 1999. The
Offering commenced on October 5, 1999. All 3,737,500 shares of Common Stock
registered under the Registration Statement (including 487,500 shares sold
pursuant to the exercise of the Underwriters' over-allotment option) were sold
at a price of $10.00 per share. The aggregate price of the Offering amount
registered was $37.4 million. In connection with the Offering, the Company paid
an aggregate of $2.6 million in underwriting discounts and commissions to the
Underwriters. In addition, the following table sets forth all expenses incurred
in connection with the Offering, other than underwriting discounts and
commissions.

   After deducting the underwriting discounts and commissions and the Offering
expenses described above, the Company received net proceeds from the Offering
of approximately $33.3 million. The Company intends to use the proceeds for
general corporate purposes as described in the prospectus for the Offering.
None of the Company's net proceeds of the Offering were paid directly or
indirectly to any director, officer, general partner of the Company or their
associates, persons owning 10% or more of any class of equity securities of the
Company, or an affiliate of the Company.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

OVERVIEW

   We are a leading provider of integrated, multifunction telecommunications
systems. We were incorporated in May 1994 and began operations in July 1994.
From inception through July 1996, we were a development-stage company and had
no revenues. During this period, our operating activities consisted primarily
of developing our initial product, recruiting personnel, raising capital and
building our corporate infrastructure. We first recognized revenues from
product sales of our Quantum board and AltiWare software in July 1996. We
generated net revenues of $6.6 million in fiscal year 1999, $3.9 million in
fiscal year 1998 and $1.4 million in fiscal year 1997. As of September 30,
1999, we had an accumulated deficit of $16.7 million.

   We derive our revenues from sales of our AltiServ system, which includes
Quantum boards, Triton boards and AltiWare software. Software sales currently
make up less than 11% of our net revenues. We believe software sales will
comprise a greater portion of our net revenues in the future. Product revenues
consist of

                                       15
<PAGE>

sales to end users (including dealers) and to distributors. Revenues from
product sales to end users are recognized upon shipment. We defer recognition
of sales to distributors until they resell our products to their customers.
Under our distribution contracts, a distributor has the right in some
circumstances to return products it determines are overstocked, so long as it
provides an offsetting purchase order for products in an amount equal to or
greater than the dollar value of the returned products. In addition, we afford
distributors protection from subsequent price reductions.

   Our cost of revenues consists of component and material costs, direct labor
costs, provisions for excess and obsolete inventory, warranty costs and
overhead related to manufacturing our products. Software sales typically carry
a higher gross margin than hardware sales.

   We have experienced operating losses and negative cash flows from operations
in each quarterly and annual period since our inception and we currently expect
to continue to incur losses for the foreseeable future. We have not recognized
any future tax benefits of our cumulative net operating losses due to
uncertainty as to future realizability.

</TABLE>

 Fiscal Year Ended September 30, 1999 Compared to Fiscal Year Ended September
 30, 1998

   Revenues, net. Revenues consist of sales to end users (including dealers)
and to distributors. Net revenues increased from $3.9 million in fiscal year
1998 to $6.6 million in fiscal year 1999, representing an increase of 69.7%.
This change was primarily from increased market acceptance of our products
through our main distributors. Sales through Ingram Micro and Tech Data
accounted for approximately 19% and 27%, respectively, of our revenues in
fiscal year 1999, and approximately 3% and 24%, respectively, of our revenues
in fiscal year 1998.

   Cost of revenues. Cost of revenues in fiscal year 1999 increased to $3.3
million from approximately $2.5 million in fiscal year 1998. Cost of revenues
consists primarily of component and material costs, direct labor costs,
provisions for excess and obsolete inventory, warranty costs and overhead
related to manufacturing our products. Cost of revenues decreased as a
percentage of net revenues in fiscal year 1999 compared to fiscal

                                       16
<PAGE>

year 1998. This decrease was primarily a result of production efficiencies as
well as lower component and overhead costs due to increased production. In
addition, the cost of revenues of fiscal year 1998 includes a provision for
excess and obsolete inventory of $361,000 related primarily to the impact of
design changes to our Quantum product. As a result of higher sales and lower
costs, gross profit increased to $3.3 million in fiscal year 1999 from $1.4
million in fiscal year 1998. Although gross profit as a percentage of revenue
has increased each fiscal year, there can be no assurance that this trend will
continue in the future.

   Research and development expenses. Research and development expenses
increased to $3.7 million in fiscal year 1999 from $1.9 million in fiscal year
1998. Research and development expenses consist principally of salaries and
related personnel expenses, consultant fees and prototype expenses related to
the design, development and testing of our products. We expense our research
and development costs as incurred. The increase was primarily due to our hiring
additional engineers, as well as opening of a research and development office
in China and increases in depreciation and other related charges due to
increases in capital spending on design and simulation software. We currently
intend to increase research and development expenses in absolute dollars in the
foreseeable future to allow us to develop new products and features. Until
these new products and features are introduced, we expect this increase in
expenses to increase our net loss (or to reduce any net profits that we may
have).

   Sales and marketing expenses. Sales and marketing expenses increased to $4.3
million in fiscal year 1999 from $2.8 million in fiscal year 1998, representing
an increase of 55.9%. Sales and marketing expenses consist of compensation,
commissions and related costs for personnel engaged in sales and marketing
functions, trade show expenses, selling and promotional programs, marketing
programs and related expenses. This increase was primarily due to hiring
additional sales and marketing personnel, increasing advertising and
promotional activities and increasing training to identify and educate new
qualified authorized dealers. We currently intend to increase sales and
marketing expenses in absolute dollars as we continue to pursue new channels
and markets and to promote customer and end user awareness of the features and
benefits of our products. We expect these increased expenses to increase the
amount of our net losses (or reduce the amount of any net profits that we may
have).

   General and administrative expenses. General and administrative expenses
increased to $1.8 million in fiscal year 1999 from $675,000 in fiscal year
1998. General and administrative expenses consist primarily of salaries and
related expenses for executive, finance and administrative personnel,
recruiting expenses, professional fees and other general corporate expenses.
The increase was primarily due to legal fees related to the NetPhone litigation
(see Part I, Item 3, Legal Proceedings), hiring of additional personnel in our
finance and accounting, management information systems and administrative
groups, and an increase in related facilities expenses and professional
services expenses. We currently intend to increase general and administrative
expenses in absolute dollars, as we add personnel and incur additional costs
resulting from the growth of our business. We expect these increased expenses
to increase the amount of our net losses (or reduce the amount of any net
profits that we may have).

   Deferred stock compensation expense. Deferred stock compensation expense was
$770,000 in fiscal year 1999 as compared to $164,000 for fiscal year 1998.
Deferred stock compensation expense reflects the amortization of stock
compensation charges resulting from granting stock options at exercise prices
below the deemed fair value of our common stock on the dates the options were
granted. We are amortizing these amounts using the straight-line method over
the vesting period of the stock options. We expect to amortize approximately
$973,000 of this deferred stock compensation in fiscal year 2000, $973,000 in
fiscal year 2001, $809,000 in fiscal year 2002 and $203,000 in fiscal year 2003
and doing so will increase our loss (or reduce any profits that we may have).

   Interest and other income, net. Net interest and other income increased to
$360,000 in fiscal year 1999 from $246,000 in fiscal year 1998. This increase
was due primarily to higher average cash and cash equivalents balances between
periods.

 Fiscal Year Ended September 30, 1998 Compared to Fiscal Year Ended September
 30, 1997

   Revenues, net. Net revenues increased to $3.9 million in fiscal year 1998
from $1.4 million in fiscal year 1997, representing an increase of 182.1%. This
increase resulted primarily from increased sales of our Quantum boards and
increased sales due to the addition of Tech Data and Ingram Micro as
distributors of our products. Sales to Tech Data accounted for 10% of our net
revenues in fiscal year 1997 and for 24% of our net revenues in fiscal year
1998.

   Cost of revenues. Cost of revenues increased to $2.5 million in fiscal year
1998 from $1.0 million in fiscal year 1997. This increase was due primarily to
increased sales of our products and a higher provision for excess and obsolete
inventory related primarily to the impact of design changes in our Quantum
product, offset by higher volume of lower cost software products and cost
reductions in our manufacturing process. As a result, gross profit increased to
$1.4 million in fiscal year 1998 from $339,000 in fiscal year 1997.

   Research and development expenses. Research and development expenses
increased to $1.9 million in fiscal year 1998 from $1.5 million in fiscal year
1997, representing an increase of 28.7%. The increase was primarily related to
increases in personnel and personnel related costs and increases in
depreciation and other related charges due to capital spending on design and
simulation software.

   Sales and marketing expenses. Sales and marketing expenses increased to $2.8
million in fiscal year 1998 from $1.4 million in fiscal year 1997, representing
an increase of 91.3%. The increase was primarily due to the hiring of
additional sales and marketing personnel as well as increased spending for
marketing promotional programs and materials, advertising and trade show
expenses.

   General and administrative expense. General and administrative expenses
remained relatively flat at $675,000 in fiscal year 1998, compared to $718,000
in fiscal year 1997.

   Deferred stock compensation expense. Deferred stock compensation expense was
$164,000 in fiscal year 1998. We did not record any deferred stock compensation
expense in fiscal year 1997.

   Interest and other income, net. Net interest and other income increased to
$246,000 in fiscal year 1998 from $206,000 in fiscal year 1997, representing an
increase of 19.4%. This increase was due to higher average cash balances in
fiscal year 1998 due to our preferred stock financings.

 Liquidity and Capital Resources

   Since inception, we have financed our operations primarily from the sale of
private equity securities. We have raised an aggregate of $24.7 million, net of
offering expenses, through the sale of preferred stock. As of September 30,
1999, we had cash and cash equivalents of $5.9 million, which consist of cash
deposited in checking and money market accounts with original maturities of
less than three months. On October 8, 1999 AltiGen received cash proceeds, net
of underwriters' discounts and commissions, totaling approximately
$34.8 million upon the closing of its initial public offering.

   Net cash used in our operating activities was $5.8 million for fiscal year
1999, $3.8 million for fiscal year 1998 and $3.1 million for fiscal year 1997.
Net cash used in operating activities primarily reflected the impact of the net
loss for each of the periods.

   Net cash provided by investing activities was $335,000 for fiscal year 1999,
which was primarily a result of redemption of short-term investments. Cash used
in investing activities for fiscal year 1998 was $388,000 and $1.0 million for
fiscal year 1997. The relative decrease in cash used for investing activities
in the fiscal year 1998 as compared to the prior year was primarily due to
decreases in the net cash being invested in the year. The relative increase in
cash used for investing activities for fiscal year 1997 as compared to the
prior period was primarily due to an increase in purchases of $207,000 for
engineering capital equipment and a decrease in redemption of short-term
investments of $2.0 million between the periods.

                                       18
<PAGE>

   Net cash provided by financing activities was $4.4 million for fiscal year
1999. Cash provided by financing activities was $9.2 million for fiscal year
1998 and $3.3 million in fiscal year 1997. The decrease in cash provided by
financing activities from fiscal year 1999 as compared to the prior period was
primarily due to lower proceeds from the issuance of series D preferred stock
as well as $1.5 million of costs related to the initial public offering of our
common stock. The increase in cash provided by financing activities for fiscal
year 1998 as compared to the prior period was primarily due to $1.4 million in
net proceeds from our issuance of series C preferred stock and $7.8 million in
net proceeds from our issuance of series D preferred stock.

   We currently believe that the net proceeds from the Company's initial public
offering, together with existing cash and cash equivalents balances, will
provide us with sufficient funds to finance our operations for at least the
next 12 months. Our management intends to invest our cash in excess of current
operating requirements in short-term, interest-bearing investment-grade
securities. Subsequently, we may need to raise additional funds, and additional
financing may not be available on favorable terms, if at all. We may also
require additional capital to acquire or invest in complementary businesses or
products, or obtain the right to use complementary technologies. If we can not
raise funds, if needed, 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, which could seriously harm
our business, financial condition, and results of operations. If additional
funds are raised through the issuance of equity securities, the net tangible
book value per share may decrease, the percentage ownership of then current
stockholders may be diluted, and such equity securities may have rights,
preferences or privileges senior to those of the holders of our common stock.

 Year 2000 Compliance

   Impact of the year 2000 problem. The year 2000 problem refers to the
potential for system and processing failures of date-related data as a result
of computer-controlled systems using two digits rather than four to define the
applicable year. For example, computer programs that have time-sensitive
software may recognize a date represented as "00" as the year 1900 rather than
the year 2000. This could result in a system failure or miscalculations causing
disruptions to operations, including among other things, a temporary inability
to process transactions, send invoices or engage in similar normal business
activities.

   To date, we have not experienced any year 2000 issues with any of our
internal systems or our products, and we do not expect to experience any of
them.

   Assessment. The year 2000 problem affects the computers, software and other
equipment that we use, operate or maintain for our operations. Accordingly, we
have organized a program team responsible for monitoring the assessment and
remediation status of our year 2000 issues and reporting to our management.
This project team is currently assessing the potential effect and costs of
remediating year 2000 issues for our internal systems. To date, we have not
obtained independent verification or validation to assure the reliability of
our risk and cost estimates because we do not feel that the scope of our
program warrants this time and expense.

   Internal infrastructure. We believe that we have identified most of the
major computers, software applications and related equipment used in connection
with our internal operations that need to be modified, upgraded or replaced to
minimize the possibility of a material disruption to our business. We have
begun modifying, upgrading and replacing major systems that we believe have
year 2000 issues.

   Systems other than information technology systems. In addition to computers
and related systems, the operation of office and facilities equipment, such as
fax machines, security systems and other common devices may have year 2000
issues. We are currently assessing the potential effect on and the costs of
remediating these issues, if any, for our office equipment and our facilities
in Fremont, California and Shanghai, China.

   Products. Since June 1998, we have designed our products to be year 2000
compliant and believe that using these products as documented should not cause
any year 2000-related issues. We have tested and intend

                                       19
<PAGE>

to continue to test all of our products introduced since September 1998 for
year 2000 issues. While we believe these products are year 2000 compliant, it
is impractical for us to test these products in every telecommunications
systems environment or with all available combinations of our products with
components supplied by our customers or other third-party suppliers. As a
result, there may be situations where the combination of these products working
with components supplied by other third parties could result in year 2000
issues.

   Two versions of our AltiWare CE software product introduced before September
1998 were not designed specifically to be year 2000 compliant. These versions
are currently being used on a small number of end user systems. As a result, we
have decided not to test these versions for year 2000 compliance. Instead, we
have notified all of our customers and advised them to upgrade any systems that
are using these older versions. We have and will continue to offer users who
request it a free software upgrade to a later version of AltiWare CE that is
year 2000 compliant. However, users who do not upgrade may experience year 2000
issues and may make potentially damaging claims against us. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Certain Factors Affecting Business, Operating Results, and Financial
Condition."

   Costs of remediation. We currently anticipate that our total cost of
addressing our year 2000 issues will be $50,000, of which approximately $39,000
has been incurred through September 30, 1999. We do not have a separate
information technology or similar budget. The cost of addressing year 2000
issues will be reported as a general and administrative expense. We have not
deferred any material information technology projects due to our year 2000
efforts.

   Suppliers. We are contacting third-party suppliers of components and our key
subcontractors used in the manufacturing of our products to identify and, to
the extent possible, resolve issues relating to the year 2000 issue. While we
expect that we will be able to resolve any significant year 2000 issue
identified with these third parties, because we have limited to no control over
the actions of these parties, there is no assurance that these third parties
will remediate any or all of the year 2000 issues identified. Any failure of
any of these third parties to timely resolve year 2000 issues with either their
products sold to us or their internal systems could have a material adverse
effect on our business, operating results and financial condition.

   Most likely consequence of year 2000 issues. We expect to identify and
resolve all year 2000 issues that could materially adversely affect our
business operations. However, for the reasons discussed above, we believe that
it is not possible to determine with complete certainty that all year 2000
issues affecting us have been identified or corrected. As a result, we believe
that the following consequences are possible:

  .  operational inconveniences and inefficiencies for us, our contract
     manufacturers and our customers that will divert our management's time
     and attention and our financial and human resources from ordinary
     business activities;

  .  business disputes and claims for pricing adjustments or penalties by our
     customers due to year 2000 issues, which we believe will be resolved in
     the ordinary course of business; and

  .  business disputes alleging that we failed to comply with the terms and
     conditions of contracts or industry standards of performance that result
     in litigation.

   Contingency plans. We are currently developing contingency plans to be
implemented if our efforts to identify and correct year 2000 issues affecting
our internal systems are not effective. Depending on the systems affected,
these plans could include:

  .  accelerated replacement of affected equipment or software;

  .  short- to medium-term use of backup equipment and software;

  .  increased work hours for our personnel; and

  .  use of contract personnel to correct, on an accelerated schedule, any
     year 2000 issues that arise or to provide manual workarounds for
     information systems.

                                       20
<PAGE>

   Our implementation of any of these contingency plans could have a material
adverse effect on our business, operating results and financial conditions.

CERTAIN FACTORS AFFECTING BUSINESS, OPERATING RESULTS, AND FINANCIAL CONDITION

 Risks Related to AltiGen

  We have a history of losses and expect to incur future losses, which may
 prevent us from becoming profitable.

   We have experienced operating losses since our inception. As of September
30, 1999, we had an accumulated deficit of $16.7 million. We expect to incur
operating losses for the foreseeable future, and these losses may be
substantial. Further, we expect our operating cash flows to be negative for the
foreseeable future. Because we expect increased expenditures for product
development and general and administrative expenses, and substantial increases
in sales and marketing expenses, we will need to increase revenues
significantly to achieve profitability and positive operating cash flows. Even
if we do achieve profitability and positive operating cash flows, we may not be
able to sustain or increase profitability or positive operating cash flows on a
quarterly or annual basis.

  We have a limited operating history, which makes it difficult to evaluate our
 business and our future prospects.

   We shipped our first products in July 1996. As a result of our limited
operating history, we have limited financial data that you can use to evaluate
our business. You must consider our prospects in light of the risks, expenses
and challenges we might encounter because we are at an early stage of
development in a new and rapidly evolving market. To address these risks and
achieve profitability and increased sales levels, we must:

  .  establish and increase market acceptance of our technology, products and
     systems;

  .  expand our network of distributors, dealers and companies that buy our
     products in bulk, customize them for particular applications or
     customers, and resell them under their own names;

  .  introduce products and systems incorporating our technology and
     enhancements to our product applications on a timely basis;

  .  respond effectively to competitive pressures; and

  .  successfully market and support our products and systems.

   We may not successfully meet any of these challenges, and our failure to do
so will seriously harm our business and results of operations. In addition,
because of our limited operating history, we have limited insight into trends
that may emerge and harm our business.

  Our operating results vary, making future operating results difficult to
 predict.

   Our quarterly and annual operating results have varied significantly in the
past and will likely vary significantly in the future. A number of factors,
many of which are beyond our control, may cause our operating results to vary,
including:

  .  our sales cycle, which may vary substantially from customer to customer;

  .  unfavorable changes in the prices and delivery of the components we
     purchase;

  .  the size and timing of orders for our products, which may vary depending
     on the season, and the contractual terms of those orders;

  .  the size and timing of our expenses, including operating expenses and
     expenses of developing new products and product enhancements;

                                       21
<PAGE>

  .  deferrals of customer orders in anticipation of new products, services
     or product enhancements introduced by us or by our competitors; and

  .  our ability to attain and maintain production volumes and quality levels
     for our products.

   Our budgets and commitments that we have made for the future are based in
part on our expectations of future sales. If our sales do not meet
expectations, it will be difficult for us to reduce our expenses quickly, and
consequently our operating results may suffer.

   Our dealers often require immediate shipment and installation of our
products. As a result, we have historically operated with limited backlog, and
our sales and operating results in any quarter depend primarily on orders
booked and shipped during that quarter.

   Any of the above factors could harm our business, financial condition and
results of operations. We believe that period-to-period comparisons of our
results of operations are not meaningful, and you should not rely upon them as
indicators of our future performance.

  Our market is highly competitive, and we may not have the resources to
 compete adequately.

   The market for our integrated, multifunction telecommunications systems is
new, rapidly evolving and highly competitive. We expect competition to
intensify in the future as existing competitors develop new products and new
competitors enter the market. We believe that a critical component to success
in this market is the ability to establish and maintain strong partner and
customer relationships with a wide variety of domestic and international
providers. If we fail to establish or maintain these relationships, we will be
at a serious competitive disadvantage.

   We face competition from companies providing traditional private telephone
systems. Our principal competitors that produce traditional private telephone
systems are Lucent Technologies and Nortel Networks. We also compete against
providers of multifunction telecommunications systems, including Picazo
Communications, Inc. and Artisoft, Inc. We potentially face competition from
companies such as Shoreline Teleworks, Inc., NBX Corporation, acquired by 3Com
Corporation, Selsius Systems, acquired by Cisco Systems, Inc., as well as any
number of future competitors. Many of our competitors are substantially larger
than we are and have significantly greater name recognition, financial, sales
and marketing, technical, customer support, manufacturing and other resources.
These competitors may also have more established distribution channels and
stronger relationships with service providers. These competitors may be able to
respond more rapidly to new or emerging technologies and changes in customer
requirements or devote greater resources to the development, promotion and sale
of their products. These competitors may enter our existing or future markets
with solutions that may be less expensive, provide higher performance or
additional features or be introduced earlier than our solutions. We also expect
that other companies may enter our market with better products and
technologies. If any technology that is competing with ours is more reliable,
faster, less expensive or has other advantages over our technology, then the
demand for our products and services could decrease and harm our business.

   We expect our competitors to continue to improve the performance of their
current products and introduce new products or new technologies. If our
competitors successfully introduce new products or enhance their existing
products, this could reduce the sales or market acceptance of our products and
services, increase price competition or make our products obsolete. To be
competitive, we must continue to invest significant resources in research and
development, sales and marketing and customer support. We may not have
sufficient resources to make these investments or to make the technological
advances necessary to be competitive, which in turn will cause our business to
suffer. A description of our principal competitors and the competitive nature
of our market are discussed in greater detail in "Business--Competition."

                                       22
<PAGE>

  Losing either of our two key distributors would harm our business. We also
 need to establish and maintain relationships with additional distributors and
 original equipment manufacturers.

   Sales through our two key distributors, Ingram Micro Inc. and Tech Data
Corporation, accounted for 46% of our net revenues in the fiscal year ended
September 30, 1999. Our business and operating results will suffer if either
of these distributors does not continue distributing our products, fails to
distribute the volume of our products that it currently distributes or fails
to expand our customer base. We also need to establish and maintain
relationships with additional distributors and original equipment
manufacturers. We may not be able to establish, or successfully manage,
relationships with additional distribution partners. In addition, our
agreements with distributors typically provide for termination by either party
upon written notice to the other party. For example, our agreement with Tech
Data provides for termination, with or without cause, by either party upon 30
days' written notice to the other party, or upon insolvency or bankruptcy.
Generally, these agreements are non-exclusive and distributors sell products
that compete with ours. If we fail to establish or maintain relationships with
distributors and original equipment manufacturers, our ability to increase or
maintain our sales and our customer base will be substantially harmed.

  We sell our products through dealers and distributors, which limits our
 ability to control the timing of our sales, and this makes it more difficult
 to predict our revenues.

   We do not recognize revenue from the sale of our products to our
distributors until these products are sold to either dealers or end users. We
have limited or no control over the timing of product sales to dealers and end
users. Our lack of control over the revenue which we recognize from our
distributors' sales to dealers and end users limits our ability to predict
revenue for any given period. Our budgets and commitments that we have made
for the future are based in part on our expectations of future sales. If our
sales do not meet expectations, it will be difficult for us to reduce our
expenses quickly, and consequently our operating results may suffer.

  We rely on sole-sourced components and third-party technology and products;
 if these components are not available, our business may suffer.

   We purchase technology from third parties that is incorporated into our
products, including virtually all of our hardware products. We order sole-
sourced components using purchase orders and do not have supply contracts for
them. One sole-sourced component, a Mitel Corporation chip, is particularly
important to our business because it is included in virtually all of our
hardware products. If we were unable to purchase an adequate supply of these
sole-sourced components on a timely basis, we would be required to develop
alternative solutions. This could entail qualifying an alternative source or
redesigning our products based on different components. Our inability to
obtain these sole-sourced components, especially the Mitel Corporation chip,
could significantly delay shipment of our products, which could have a
negative effect on our business, financial condition and results of
operations. See "Business--Manufacturing and Assembly."

  We rely on dealers to promote, sell, install and support our products, and
 their failure to do so may substantially reduce our sales and thus seriously
 harm our business.

   We rely on dealers who can provide high quality sales and support services.
As with our distributors, we compete with other telecommunications systems
providers for our dealers' business, as our dealers generally market competing
products. If a dealer promotes a competitor's products to the detriment of our
products or otherwise fails to market our products and services effectively,
we could lose market share. In addition, the loss of a key dealer or the
failure of dealers to provide adequate customer service could cause our
business to suffer. If we do not properly train our dealers to sell, install
and service our products, our business will suffer.

  Software or hardware errors may seriously harm our business and damage our
 reputation, causing loss of customers and revenues.

   Users expect telephone systems to provide a high level of reliability. Our
products are inherently complex and may have undetected software or hardware
errors. We have detected and may continue to detect errors and

                                      23
<PAGE>

product defects in our installed base of products, new product releases and
product upgrades. For example, a small number of our boards failed and were
returned. We have replaced these boards and made certain design changes. We
cannot be sure that the problem has been fully addressed and that similar or
different problems may not occur in existing or new boards in the future. In
addition, end users may install, maintain and use our products improperly or
for purposes for which they were not designed. These problems may degrade or
terminate the operation of our products, which could cause end users to lose
telephone service, cause us to incur significant warranty and repair costs,
damage our reputation and cause significant customer relations problems. Any
significant delay in the commercial introduction of our products due to errors
or defects, any design modifications required to correct these errors or
defects or any negative effect on customer satisfaction as a result of errors
or defects could seriously harm our business, financial condition and results
of operations.

   Any claims brought because of problems with our products or services could
seriously harm our business, financial condition and results of operations. We
currently offer a one-year hardware guarantee to end users. If our products
fail within the first year, we face replacement costs. Our insurance policies
may not provide sufficient or any coverage should a claim be asserted. In
addition, our introduction of products and systems with reliability, quality or
compatibility problems could result in reduced revenues, uncollectible accounts
receivable, delays in collecting accounts receivable, warranties and additional
costs. Our customers, end users or employees could find errors in our products
and systems after we have begun to sell them, resulting in product
redevelopment costs and loss of, or delay in, their acceptance by the markets
in which we compete. Further, we may experience significant product returns in
the future. Any of these events could have a material adverse effect on our
business, financial condition and results of operations.

  We may face infringement issues that could harm our business by requiring us
 to license technology on unfavorable terms or temporarily or permanently cease
 sales of key products.

   We cannot be certain that our products do not, or will not, infringe
patents, trademarks, copyrights or other intellectual property rights held by
third parties. Third parties may assert infringement claims against us. From
time to time in the ordinary course of business we have been, and we expect to
continue to be, subject to claims of alleged infringement of the patents and
intellectual property rights of others. For example, we are currently engaged
in litigation with NetPhone, Inc. In June 1999, we received a letter from
NetPhone alleging that we infringe a patent owned by NetPhone. On June 30,
1999, we filed a request for a declaration from the United States District
Court for the Northern District of California that AltiGen does not infringe
any valid claim of NetPhone's patent. NetPhone answered AltiGen's complaint on
July 13, 1999 and asserted a counterclaim against AltiGen, alleging that
AltiGen infringes the NetPhone patent. On August 11, 1999, NetPhone filed a
motion to enjoin AltiGen from making, importing, using, offering to sell or
selling a device under the name Quantum. On September 7, 1999, we filed our
Opposition to NetPhone's motion. NetPhone's Motion has not yet been decided. A
hearing was held on NetPhone's Motion for Preliminary Injunction on December
13, 1999, and the Court has taken the matter under submission. Although we
intend to continue to litigate the lawsuit and to contest NetPhone's Motion
vigorously, litigation is subject to inherent uncertainties and, therefore, we
cannot assure you that we will prevail or that we can avoid an adverse outcome.

   This litigation could be costly and time consuming. An adverse outcome could
require us to obtain a license from NetPhone or require us to cease sales of
what NetPhone calls the "Quantum device" and possibly alter the design of some
of our products. For the fiscal year 1999, sales of our Quantum board
constituted 82% of our revenues. Accordingly, an adverse outcome could
materially harm our business. See "Legal Proceedings."

   More generally, litigation related to these types of claims may require us
to acquire licenses under third-party patents which may not be available on
acceptable terms, if at all. We believe that an increasing portion of our
revenues in the future will come from sales of software applications for our
hardware products. The software market has traditionally experienced widespread
unauthorized reproduction of products in violation of developers' intellectual
property rights. This activity is difficult to detect, and legal proceedings to
enforce developers' intellectual property rights are often burdensome and
involve a high degree of uncertainty and substantial costs.

                                       24
<PAGE>

  Any failure by us to protect our intellectual property could harm our
 business and competitive position.

   Our success depends, to a certain extent, upon our proprietary technology.
We currently rely on a combination of patent, trade secret, copyright and
trademark law, together with non-disclosure and invention assignment
agreements, to establish and protect the proprietary rights in the technology
used in our products.

   Although we have filed patent applications, we are not certain that our
patent applications will result in the issuance of patents, or that any
patents issued will provide commercially significant protection to our
technology. In addition, others may independently develop substantially
equivalent proprietary information not covered by patents to which we own
rights, may obtain access to our know-how or may claim to have issued patents
that prevent the sale of one or more of our products. Also, it may be possible
for third parties to obtain and use our proprietary information without our
authorization. Further, the laws of some countries, such as those in Japan,
one of our target markets, may not adequately protect our intellectual
property or may be uncertain. Our success also depends on trade secrets that
cannot be patented and are difficult to protect. If we fail to protect our
proprietary information effectively, or if third parties use our proprietary
technology without authorization, our competitive position and business will
suffer. A description of our dependence on proprietary technology is discussed
in greater detail in "Business--Intellectual Property."

  Our products may not meet the legal standards required for their sale in
 some countries; if we cannot sell our products in these countries, our
 results of operations may be seriously harmed.

   The United States and other countries in which we intend to sell our
products have standards for safety and other certifications that must be met
for our products to be legally sold in those countries. We have tried to
design our products to meet the requirements of the countries in which we sell
or plan to sell them. We have also obtained or are trying to obtain the
certifications that we believe are required to sell our products in these
countries. However, we cannot guarantee that our products meet all of these
standards or that we will be able to obtain any certifications required. In
addition, there is, and will likely continue to be, an increasing number of
laws and regulations pertaining to the products we offer and may offer in the
future. These laws or regulations may include, for example, more stringent
safety standards, requirements for additional or more burdensome
certifications or more stringent consumer protection laws.

   If our products do not meet a country's standards or we do not receive the
certifications required by a country's laws or regulations, then we may not be
able to sell those products in that country. This may seriously harm our
results of operation by reducing our sales or requiring us to invest
significant resources to conform our products to these standards.

  Our market is subject to changing preferences; failure to keep up with these
 changes would result in our losing market share, thus seriously harming our
 business, financial condition and results of operations.

   Our customers and end users expect frequent product introductions and have
changing requirements for new products and features. Therefore, to be
competitive, we will need to develop and market new products and product
enhancements that respond to these changing requirements on a timely and cost-
effective basis. Our failure to do so promptly and cost-effectively would
seriously harm our business, financial condition and results of operations.
Also, introducing new products could require us to write off existing
inventory as obsolete, which could harm our results of operations.

  If we do not manage our growth effectively, our business will suffer.

   We may not be successful in managing any future growth. We have expanded
our operations rapidly since our inception. In order to manage this expansion
and to grow in the future, we will need to expand or enhance our management,
manufacturing, research and development and sales and marketing capabilities.
We may not be able to hire the management, staff or other personnel required
to do so.

                                      25
<PAGE>

   We may not be able to install adequate control systems in an efficient and
timely manner, and our current or planned operational systems, procedures and
controls may not be adequate to support our future operations. Difficulties in
installing and implementing new systems, procedures and controls may
significantly burden our management and our internal resources. Delays in the
implementation of new systems or operational disruptions when we transition to
new systems would impair our ability to accurately forecast sales demand,
manage our product inventory and record and report financial and management
information on a timely and accurate basis.

   Lead times for materials and components used in the assembly of our products
vary significantly, and depend on factors such as the supplier, contract terms
and demand for a component at a given time. If orders do not match forecasts,
we may have excess or inadequate inventory of certain materials and components,
which may seriously harm our business, financial condition and results of
operations.

  Our planned expansion in international markets will involve new risks that
 our previous domestic operations have not prepared us to address; our failure
 to address these risks could harm our business, financial condition and
 results of operations.

   For the fiscal year ended September 30, 1999, approximately 8% of our net
revenues came from customers outside of the United States. We intend to expand
our international sales and marketing efforts. Our efforts are subject to a
variety of risks associated with conducting business internationally, any of
which could seriously harm our business, financial condition and results of
operations. These risks include:

  .  tariffs, duties, price controls or other restrictions on foreign
     currencies or trade barriers, such as import or export licensing imposed
     by foreign countries, especially on technology;

  .  potential adverse tax consequences, including restrictions on
     repatriation of earnings;

  .  fluctuations in foreign currency exchange rates, which could make our
     products relatively more expensive in foreign markets; and

  .  conflicting regulatory requirements in different countries that may
     require us to invest significant resources customizing our products for
     each country.

  We need additional qualified personnel to maintain and expand our business;
 our failure to promptly attract and retain qualified personnel may seriously
 harm our business, financial condition and results of operations.

   We depend, in large part, on our ability to attract and retain highly
skilled personnel, particularly engineers and sales and marketing personnel. We
need highly trained technical personnel to design and support our server-based
telecommunications systems. In addition, we need highly trained sales and
marketing personnel to expand our marketing and sales operations in order to
increase market awareness of our products and generate increased revenues.
Competition for highly trained personnel is intense, especially in the San
Francisco Bay Area where most of our operations are located. We cannot be
certain that we will be successful in our recruitment and retention efforts. If
we fail to attract or retain qualified personnel or suffer from delays in
hiring required personnel, our business, financial condition and results of
operations may be seriously harmed.

  Our facility is vulnerable to damage from earthquakes and other natural
 disasters; any such damage could seriously or completely impair our business.

   We perform final assembly, software installation and testing of our products
at our facility in Fremont, California. Our facility is located on or near
known earthquake fault zones and is vulnerable to damage from fire, floods,
earthquakes, power loss, telecommunications failures and similar events. If
such a disaster occurs, our ability to perform final assembly, software
installation and testing of our products at our facility would be seriously, if
not completely, impaired. If we were unable to obtain an alternative place or
way to perform these functions, our business, financial condition and results
of operations would suffer. The insurance we maintain may not be adequate to
cover our losses against fires, floods, earthquakes and general business
interruptions.

                                       26
<PAGE>

  Our strategy to outsource assembly and test functions in the future could
 delay delivery of products, decrease quality or increase costs.

   Based on volume or customer requirements, we may begin outsourcing some
assembly and test functions. In addition, we may determine that we need to
establish assembly and test operations overseas to better serve our
international customers. Establishing overseas assembly and test operations may
be more difficult or take longer than we anticipate. This outsourcing strategy
involves certain risks, including the potential lack of adequate capacity and
reduced control over delivery schedules, manufacturing yield, quality and
costs. In the event that any significant subcontractor were to become unable or
unwilling to continue to manufacture or test our products in the required
volumes, we would have to identify and qualify acceptable replacements. Finding
replacements could take time, and we cannot be sure that additional sources
would be available to us on a timely basis. Any delay or increase in costs in
the assembly and testing of products by third-party subcontractors could
seriously harm our business, financial condition and results of operations. Our
manufacturing and assembly operations are discussed in greater detail in
"Business--Manufacturing and Assembly."

  We face year 2000 risks that, if realized, could disrupt our business
 operations, resulting in harm to our business, financial condition and results
 of operation.

   Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. Beginning in the year
2000, these date code fields will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, within
this year, computer systems and software may need to be upgraded to comply with
these year 2000 requirements. Our failure to complete implementation of the
required changes to address year 2000 requirements prior to the year 2000 might
result in significant difficulties in our administration of management
information systems and consequently have a material adverse effect on our
business, financial condition and results of operations. We have not yet
completed a review of the preparations of all of our major suppliers,
distributors and shippers to be year 2000 compliant. We therefore do not have a
basis to assess the impact, if any, that the year 2000 issue will have on our
suppliers, distributors, dealers and shippers and, consequently, on us. Failure
by our suppliers, distributors, dealers and shippers and other parties with
whom we do business to address year 2000 issues could negatively affect our
ability to distribute products for some period of time and otherwise disrupt
our business operations.

   We also face the risk that some of our products may not be year 2000
compliant. If any of our end user customers experience year 2000 issues as a
result of their use of our products, those end users could assert claims
against us for damages which, if successful, could harm our business, financial
condition or results of operations. In addition, many of our products have some
third-party technologies embedded in them, and we expect our products to be
increasingly integrated into enterprise systems involving sophisticated
hardware and complex software products. We cannot adequately evaluate these
technologies or products for year 2000 compliance. We may face claims under our
warranties, or otherwise, based on year 2000 problems in other companies'
products, or issues arising from the integration of multiple products within an
overall system. We are in the process of testing our products to identify any
year 2000 issues. For a more detailed description of our year 2000 assessment,
see "Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Compliance."

 Risks Related to the Industry

  Integrated, multifunction telecommunications systems may not achieve
 widespread acceptance, and our fixed costs in the short run could cause our
 operating results and business to suffer.

   The market for integrated, multifunction telecommunications systems is
relatively new and rapidly evolving. Businesses have invested substantial
resources in the existing telecommunications infrastructure, including
traditional private telephone systems, and may be unwilling to replace these
systems in the near term

                                       27
<PAGE>

or at all. Businesses may also be reluctant to adopt integrated, multifunction
telecommunications systems because of their concern about the current
limitations of data networks, including the Internet. For example, end users
sometimes experience delays in receiving calls and reduced voice quality
during calls when routing calls over data networks. Moreover, businesses that
begin to route calls over the same networks that currently carry only their
data may also experience these problems if the networks do not have sufficient
capacity to carry all of these communications at the same time. We incur many
fixed costs in anticipation of a certain level of revenues. If businesses
defer purchasing or decide not to purchase integrated, multifunction
telecommunications systems and the market for our products does not grow or
grows substantially more slowly than we anticipate, our operating results will
suffer and our business will be harmed because we will be unable to reduce
fixed costs in the short term to offset the reduced revenues.

  Future regulation or legislation could harm our business or increase our
 cost of doing business.

   In April 1998, the Federal Communications Commission submitted a report to
Congress stating that it may regulate certain Internet services if it
determines that such Internet services are functionally equivalent to
conventional telecommunications services. The increasing growth of the voice
over data network market and the popularity of supporting products and
services, however, heighten the risk that national governments will seek to
regulate the transmission of voice communications over networks such as the
Internet. In addition, large telecommunications companies may devote
substantial lobbying efforts to influence the regulation of this market so as
to benefit their interests, which may be contrary to our interests. These
regulations may include, for example, assessing access or settlement charges,
imposing tariffs or imposing regulations based on encryption concerns or the
characteristics and quality of products and services. Future laws, legal
decisions or regulations, as well as changes in interpretations of existing
laws and regulations, could require us to expend significant resources to
comply with them. In addition, these future events or changes may create
uncertainty in our market that could reduce demand for our products.

  Evolving standards may delay our product introductions, increase our product
 development costs or cause end users to defer or cancel plans to purchase our
 products, any of which could adversely affect our business.

   The standards in our market are still evolving. These standards are
designed to ensure that integrated, multifunction telecommunications products
from different manufacturers can operate together. Some of these standards are
proposed by other participants in our market, including some of our
competitors, and include proprietary technology. In recent years, these
standards have changed, and new standards have been proposed, in response to
developments in our market. Our failure to conform our products to existing or
future standards may limit their acceptance by market participants. We may not
anticipate which standards will achieve the broadest acceptance in our market
in the future, and we may take a significant amount of time and expense to
adapt our products to these standards. We may also have to pay additional
royalties to developers of proprietary technologies that become standards in
our market. These delays and expenses may seriously harm our results of
operations. In addition, customers and users may defer or cancel plans to
purchase our products due to concerns about the ability of our products to
conform to existing standards or to adapt to new or changed standards, and
this could seriously harm our results of operations.

FORWARD-LOOKING STATEMENTS

   Some of the information in this Annual Report on Form 10-K contains
forward-looking statements within the meaning of the federal securities laws.
These statements include, among others, statements regarding the following:
expected product revenues as a percentage of sales, expense levels, use of
proceeds, liquidity and expansion strategy and possible effects of changes in
government regulation. Forward-looking statements typically are identified by
use of terms such as "may", "will", "expect", "anticipate", "intend",
"estimate" and similar words, although some forward-looking statements are
expressed differently. You should be aware that our actual results could
differ materially from those contained in the forward-looking statements

                                      28
<PAGE>

due to a number of factors, including insufficient capital resources, inability
to integrate acquired businesses successfully, adverse economic conditions and
unanticipated difficulties in product development. You should also consider
carefully the statements under "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Certain Factors Affecting
Business, Operating Results, and Financial Condition" and other sections of
this Form 10-K, which address additional factors that could cause our actual
results to differ from those set forth in the forward-looking statements.

Item 7(a). Quantitative and Qualitative Disclosures About Market Risk.

   Market Risk. Our interest income is sensitive to changes in the general
level of U.S. interest rates, particularly since the majority of our
investments are in cash equivalents and short-term instruments. Due to the
short-term nature of our cash equivalents and investments, we have concluded
that there is no material market risk exposure. Therefore, no quantitative
tabular disclosures are required.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To AltiGen Communications, Inc.:

   We have audited the accompanying consolidated balance sheets of AltiGen
Communications, Inc. (a Delaware corporation) and its subsidiary as of
September 30, 1999 and 1998, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended September 30, 1999. These financial statements and the
schedule referred to below are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements and
schedule based on our audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of AltiGen Communications,
Inc. and its subsidiary as of September 30, 1999 and 1998, and the results of
their operations and their cash flows for each of the three years in the period
ended September 30, 1999, in conformity with generally accepted accounting
principles.

   Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed under Item 14(a) 2
is presented for purposes of complying with the Securities and Exchange
Commission's rules and is not a part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in our audits of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               September 30, 1999

1. ORGANIZATION OF THE COMPANY:

   AltiGen Communications, Inc. (the "Company") was incorporated in California
on May 18, 1994 and began operations in July of that year. In June 1999, the
Company reincorporated in Delaware. The Company designs, manufactures, and
markets server-based telecommunications systems that allow businesses to use
data networks such as the Internet and the traditional telephone network
interchangeably to carry voice and data communications.

   The Company is subject to the risks associated with early stage technology
companies. These risks include, but are not limited to: history of losses,
limited operating history, dependence on a smaller number of key individuals,
customers and suppliers, competition from larger, more established companies,
the continued need for additional financing, the impact of rapid technological
changes and changes in customer demand/requirements. There is no assurance that
the Company's efforts will be successful.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

 Principles of Consolidation

   The Company's consolidated financial statements reflect the operations of
the Company and its wholly-owned subsidiary. The subsidiary is located in
Shanghai, China and was incorporated in November 1998. As of September 30 1999,
the Company had approximately $28,000 in long lived assets located in China.
All significant intercompany transactions and balances have been eliminated.
The Company's fiscal year end is September 30. Unless otherwise stated, all
references to 1999, 1998 and 1997 refer to the twelve months ended September 30
of that year.

 Use of Estimates in Preparation of Financial Statements

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

 Reclassifications

   Certain prior year amounts have been reclassified to conform to the current
year presentation.

 Concentration of Risk

   Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of trade receivables. The Company performs
ongoing credit evaluations of its customers' financial condition and requires
letters of credit whenever deemed necessary to help reduce its credit risk.
Additionally, the Company establishes an allowance for doubtful accounts based
upon factors surrounding the credit risk of specific customers, historical
trends related to past losses and other information. As of September 30, 1999
and 1998, approximately 87% and 66%, respectively, of accounts receivable were
concentrated with ten customers.

   The Company's purchases are concentrated with three suppliers and certain
key components of the Company's products are sole sourced. For fiscal years
1999 and 1998 these three suppliers provided 76% and 78%, respectively, of all
raw materials purchased. Loss of one of these suppliers could adversely impact
the Company's operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


 Cash and Cash Equivalents and Short-term Investments

   The Company considers all highly liquid investments with an original
maturity of three months or less from the date of purchase to be cash
equivalents. Investments in highly liquid financial instruments with original
maturities greater than three months but less than one year are classified as
short-term investments. As of September 30, 1999, the Company's cash and cash
equivalents consisted of commercial paper and cash deposited in checking and
money market accounts. For fiscal years 1999 and 1998, the Company did not make
any cash payments for interest or income taxes.

 Inventories

   Inventories (which include costs associated with components assembled by
third- party assembly manufacturers, as well as internal labor and overhead)
are stated at the lower of cost (first-in, first-out) or market. Provisions,
when required, are made to reduce excess and obsolete inventories to their
estimated net realizable values. Provisions for excess and obsolete inventory
totaled approximately $90,000 and $418,000 for fiscal years 1999 and 1998,
respectively. The components of inventories include:

 Prepaid Royalties

   The Company has recently developed an ISDN product which contains certain
third-party proprietary technology, which has been modified for the Company's
use. In connection with the above, the Company prepaid royalty payments to the
owner of this technology totaling $317,000 and $100,000 for fiscal year 1999
and 1998, respectively. These prepayments are included in prepaid expenses and
other current assets in the accompanying consolidated balance sheets and will
be amortized against the lesser of future product shipments or twenty-four
months. Amortization of $16,666 per month began in August 1999. Royalty
payments will be determined based on 40% of the profit (as defined) realized
from the Company's sales of this product.

 Prepaid Offering Costs

   The Company capitalized offering costs of approximately $1,461,000 as of
September 30, 1999. The costs primarily consist of legal, printing and
accounting fees related to the initial public offering of the Company's common
stock which was completed in October 1999. The prepayments are included in
prepaid expenses and other current assets in the accompanying consolidated
balance sheets and will be offset against the proceeds received from the
initial public offering (See Note 5).

 Property and Equipment

   Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the estimated useful lives of the assets, which
is three years. Depreciation expense for fiscal years 1999 and 1998 was
approximately $357,000 and $139,000, respectively. All repairs and maintenance
costs are expensed as incurred.

 Software Development Costs

   In accordance with Statement of Financial Accounting Standards ("SFAS") No.
86, "Accounting for the Costs of Computer Software to be Sold, Leased, or
Otherwise Marketed," the Company capitalizes eligible computer software
development costs upon the establishment of technological feasibility, which it
has defined as completion of a working model. The amount of costs eligible for
capitalization, after consideration of factors such as realizable value, were
not material and, accordingly, all software development costs have been charged
to research and development expense in the accompanying consolidated statements
of operations.

 Stock-Based Compensation

   The Company has adopted the disclosure provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation," which establishes a fair value
method of accounting for stock-based compensation plans. As allowed under the
provisions of SFAS No. 123, the Company applies Accounting Principle Board
Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations in accounting for its employee stock option plan (see Note 6
for a discussion of compensation cost recorded related to certain employee
stock options granted). The Company follows the provisions of SFAS No. 123 for
options granted to consultants and nonemployees. Compensation expense for such
grants for all periods presented was nominal and therefore immaterial.

 Revenue Recognition

   Revenues consist of sales to end users, including dealers, and to
distributors. Revenues from sales to end users are recognized upon shipment.
The Company provides for estimated sales returns and allowances and warranty
costs related to such sales at the time of shipment. Net revenues consist of
product revenues reduced by estimated sales returns and allowances. Sales to
distributors are made under terms allowing certain rights of return and
protection against subsequent price declines on the Company's products held by
the distributors. Upon termination, any unsold products may be returned by the
distributor for a full refund. These agreements may be canceled by either party
based on a specified notice. As a result of the above provisions, the Company
defers recognition of revenues and the proportionate costs of revenues derived
from sales to distributors until such distributors resell the Company's
products to their customers. The amounts deferred as a result of this policy
are reflected as "deferred revenue" in the accompanying consolidated balance
sheets.

   For fiscal years 1999 and 1998, sales to four distributors of the Company's
products accounted for approximately 57% and 46% of net revenues, respectively.

   The following customers accounted for more than 10% of net revenues:

   Revenues derived from sales to customers outside of the United States,
primarily in Japan, accounted for approximately 8% and 7% of the Company's net
revenues for fiscal years 1999 and 1998, respectively.

   The Company offers free software upgrades to users of their products when an
error in the software has been subsequently detected. Accordingly, the Company
offers free software upgrades for certain products that were determined to not
be Year 2000 compliant.

 Computation of Basic Net Loss Per Share and Unaudited Pro Forma Basic Net Loss
 Per Share

   Historical net loss per share has been calculated under SFAS No. 128,
"Earnings per Share." SFAS No. 128 requires companies to compute earnings per
share under two methods (basic and diluted). Basic net loss per share is
calculated by dividing net loss by the weighted average shares of common stock
outstanding during the period. No diluted loss per share information has been
presented in the accompanying consolidated statements of operations since
potential common shares from the conversion of preferred stock, stock options
and warrants are antidilutive. The Company evaluated the requirements of the
Securities and Exchange Commission Staff Accounting Bulletin No. 98 ("SAB No.
98"), and concluded that there are no nominal issuances of common stock or
potential common stock which would be required to be shown as outstanding for
all periods presented herein as outlined in SAB No. 98.

   Unaudited pro forma basic net loss per share has been calculated assuming
the conversion of the outstanding preferred stock into an equivalent number of
shares of common stock, as if the shares had been converted on the dates of
their issuance.

 Comprehensive Income

   In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income," which establishes standards for
reporting and presentation of comprehensive income. SFAS No. 130, which was
adopted by the Company in the first quarter of fiscal year 1998, requires
companies to report a new measurement of income. "Comprehensive Income (Loss)"
is to include as other comprehensive income foreign currency translation gains
and losses and other unrealized gains and losses that have historically been
excluded from net income (loss) and reflected instead in equity. The Company
does not have any items of other comprehensive income and is, therefore, not
required to report comprehensive income.

 Segment Reporting

   In June 1997, the FASB also issued SFAS No. 131, "Disclosures About Segments
of an Enterprise and Related Information." SFAS No. 131 was adopted by the
Company beginning on October 1, 1997. This statement establishes standards for
disclosures about operating segments, products and services, geographic areas
and major customers. The Company is organized and operates as one operating
segment. The Company operates primarily in one geographic area, the United
States.

 Accounting for Derivative Instruments and Hedging Activities

   In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which requires companies to record
derivative financial instruments on the balance sheet as assets or liabilities,
measured at fair value. Gains or losses resulting from changes in the values of
those derivatives would be accounted for depending on the use of the derivative
and whether it qualifies for hedging accounting. The key criterion for hedge
accounting is that the hedging relationship must be highly effective in
achieving offsetting changes in fair value or cash flows. In June 1999, the
FASB issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities--Deferral of the Effective Date of FASB Statement No. 133," which
amends SFAS No. 133 to be effective for all fiscal quarters of all fiscal years
beginning after June 15, 2000 (or October 1, 2000 for AltiGen). This statement
will not have a material impact on the financial condition or results of the
operations of the Company.

 Start-up Costs

   In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position No. 98-5, "Reporting on the Costs of Start- Up
Activities" ("SOP No. 98-5"). SOP No. 98-5 requires that all start-up costs
related to new operations must be expensed as incurred. In addition, all start-
up costs that were previously capitalized must be written off when SOP No. 98-5
is adopted. The Company adopted SOP No. 98-5 in fiscal 1999. The adoption did
not have a material impact on the Company's financial position or results of
operations.

 Stock Split and Reincorporation

   In July 1999, the Company's Board of Directors approved a one-for-1.66965
reverse stock split of its convertible preferred and common stock. All
convertible preferred and common share amounts in the accompanying consolidated
financial statements have been adjusted retroactively to give effect to this
split.

   In June 1999, the Company's Board of Directors approved the reincorporation
of the Company in Delaware. Upon reincorporation, the Company issued new shares
with a par value of $0.001 per share to all convertible preferred and common
stockholders. All convertible preferred and common share amounts in the
accompanying consolidated financial statements have been adjusted retroactively
to give effect to this change.

3. NOTES PAYABLE:

   As of September 30, 1998, the Company had non-interest-bearing notes payable
of $365,687 outstanding to consultants in exchange for services received by the
Company primarily during fiscal years 1996 and 1997. During fiscal year 1999,
the Company issued additional notes payable of $12,798 to consultants. The
Company had agreed to issue a total of 197,026 shares of preferred stock at the
fair market values on the dates of the respective issuances of the notes, which
was $1.17-$8.35 per share, as payment for the notes. In June 1999, the note
holders agreed to accept common shares on a 1:1 basis in lieu of preferred
shares. Such common shares were issued in June 1999 and are reflected in the
accompanying consolidated statements of stockholders' equity.

4. COMMITMENTS AND CONTINGENCIES:

 Commitments

   The Company leases its facilities under various operating lease agreements
expiring on various dates through February 2002. Rent expense for all operating
leases totaled approximately $361,000 and $167,000 for fiscal years 1999 and
1998, respectively. Minimum future lease payments under all noncancellable
operating leases as of September 30, 1999 are as follows:

 Contingencies

   The Company is engaged in litigation with NetPhone, Inc. (NetPhone), a
competitor, related to alleged infringement by the Company of a NetPhone
patent. The Company has responded to NetPhone's complaint in

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

the U.S. District Court requesting a declaration that the Company has not
infringed any valid claim of NetPhone's patent. NetPhone, in turn, has filed a
motion against the Company, seeking to enjoin the Company from making,
importing, using, selling or offering to sell its Quantum Board, a product
which accounted for approximately 82% of the Company's revenues for fiscal year
1999. The Company has responded by filing an opposition to NetPhone's motion.
NetPhone's Motion has not yet been decided. A hearing was held on NetPhone's
Motion for Preliminary Injunction and the Court has taken the matter under
submission. AltiGen intends to vigorously defend itself against the allegations
and motion asserted by NetPhone and based upon advice of AltiGen's patent
prosecution counsel, does not believe that the ultimate outcome of this matter
will have a material impact on the Company's financial condition or results of
its operations. However, litigation of this nature is subject to inherent
uncertainties and therefore, there is no assurance that the Company will
prevail in the litigation or that an adverse outcome will not adversely affect
the Company's business or financial condition.

5. INITIAL PUBLIC OFFERING:

   On October 4, 1999, the Company completed its initial public offering of
3,737,500 shares of common stock (including the exercise of the underwriters
over-allotment option) and realized net proceeds of $33.3 million. Concurrent
with the closing of the initial public offering, 8,146,156 shares of
convertible preferred stock were converted into 8,146,156 shares of common
stock.

   The holders of series A, B, C and D preferred stock are entitled to receive
non-cumulative dividends at an annual rate of $0.08, $0.12, $0.17 and $0.83 per
share, respectively. Such dividends shall be payable only when, as, and if
declared by the Board of Directors. No dividends shall be payable on any common
stock until dividends to series A, B, C and D preferred stock have been paid or
declared by the Board of Directors. Additionally, no dividends shall be paid or
declared for any series of preferred stock unless at the same time a like
proportionate dividend, ratably in proportion to the respective annual dividend
rates fixed therefore, is paid and declared for the shares of all other series
preferred stock. As of September 30, 1999 and 1998, no dividends had been
declared.

 Liquidation Preference

   In the event of any liquidation, dissolution or winding up of the Company,
holders of series A, B, C and D preferred stock are entitled to receive, in
preference to holders of common stock, the amounts of $0.83, $1.17, $1.67 and
$8.35 per share, respectively, plus all declared but unpaid dividends. Such
amounts will be adjusted for any stock split, stock dividends and
recapitalizations. After payment of the above amounts, holders of common stock
are entitled to receive the amount of $0.83 per share, adjusted for any stock
split, stock dividends and recapitalizations. If such amounts are not available
to sufficiently satisfy the full preferential amount, the entire assets of the
Company will be distributed to the preferred stockholders in proportion to
their aggregate liquidation preference of the shares of preferred stock held.
After payment to the holders of preferred stock and common stock of the above
preferential amounts, the entire remaining assets and funds of the Company
shall be distributed to the holders of common stock and preferred stock in
proportion to the shares of common stock and preferred stock, on an as-
converted basis, held by these holders.

 Voting Rights

   The holders of the series A, B, C and D preferred stock are entitled to the
number of votes equal to the number of shares of common stock into which such
preferred stock is convertible.

 Conversion

   Each share of series A, B, C and D preferred stock is convertible into one
share of common stock at (a) the date specified by vote or written consent by
preferred stockholders of at least two-thirds of outstanding preferred stock or
(b) the consummation of the Company's sale of common stock in an underwritten
public offering which results in aggregate cash proceeds to the Company in
excess of $10,000,000 and the public offering price is not less than $8.35 per
share. The conversion rate is subject to adjustment for dilution, including,
but not limited to, stock splits, stock dividends and stock combinations (See
also Note 5).

grant. The value of common stock subject to incentive stock options that become
exercisable by any one employee in any calendar year may not exceed $100,000.
Options generally vest over a four-year period and generally expire ten years
after the date of grant.

   In 1999, the Company adopted the 1999 Stock Option Plan (the "1999 Plan")

   The Company accounts for the Plans under APB Opinion No. 25. Had
compensation expense for the Plans been determined consistent with SFAS No.

   The weighted-average grant date fair value of options granted during fiscal
years 1999, 1998 and 1997 was $1.35, $0.13 and $0.06 respectively. The fair
value of each option grant is estimated on the date of grant using the Black-
Scholes option pricing model with the following weighted-average assumptions
used for grants in 1999, 1998 and 1997: risk free interest rates ranging from
4.5%-5.5%; expected dividend yields of zero percent; expected lives of 5 years.
Because the Company has been a non-public entity during the reporting period,
it has omitted expected volatility in determining the fair value for its
options.

   In connection with the issuance of certain stock options to employees in
fiscal years 1999 and 1998, the Company has recorded deferred stock
compensation in the aggregate amount of approximately $3,892,000, representing
the difference between the deemed fair value of the Company's common stock and
the exercise price of stock options at the date of grant. The Company is
amortizing the deferred stock compensation expense over the vesting period of
four years. For fiscal year 1999 and for fiscal year 1998, amortization of
deferred stock compensation expense was approximately $770,000 and $164,000,
respectively.

   In June 1999, the Board of Directors adopted the 1999 Employee Stock
Purchase Plan (the "1999 Purchase Plan") under which 299,464 shares of common
stock were reserved for issuance to eligible employees at a price of 85% of the
lower of the fair market value of the common stock on the first day of the
offering period or a specified exercise date (last trading day in January or
July). The number of shares will be increased on the first day of each fiscal
year beginning in 2000 by the lesser of (i) 598,928 shares, (ii) 2% of the
outstanding shares on that date or (iii) a lesser amount determined by the
Board of Directors. Participants under the 1999 Purchase Plan generally may not
purchase shares on any exercise date to the extent that,

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

immediately after the grant, the participant would own stock totaling 5% or
more of the total combined voting power of all stock of the Company, or greater
than $25,000 worth of stock in any calendar year. In addition, no more than
5,989 shares may be purchased by any participant during any offering period. In
the event of a sale or merger of the Company, the Board may accelerate the
exercise date of the current purchase period to a date prior to the change of
control, or the acquiring company may assume or replace the outstanding
purchase rights under the 1999 Purchase Plan. The first offering period under
the 1999 Purchase Plan commenced on the effective date of the Company's initial
public offering and will terminate on or before July 31, 2001.

7. INCOME TAXES:

   The Company accounts for income taxes pursuant to SFAS No. 109, "Accounting
for Income Taxes." SFAS No. 109 requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns. The following is
a summary of the significant components of the company deferred tax asset as of
September 30, 1999 and 1998:

</TABLE>

   As of September 30, 1999, the Company has cumulative net operating loss
carryforwards for federal and state income tax reporting purposes of
approximately $9.7 million and $3.8 million, respectively, which expire in
various periods from 2002 to 2019. Under current tax law, net operating loss
carryforwards available in any given year may be limited upon the occurrence of
certain events, including significant changes in ownership interests, such as
an initial public stock offering.

   A valuation allowance has been recorded for the entire deferred tax asset as
a result of uncertainties, regarding realization of the asset, including
limited operating history of the Company, the lack of profitability to date and
the uncertainty over future operating profitability and taxable income.

   As of September 30, 1999 and 1998 the Company had no significant deferred
tax liabilities.
