ITEM 1: BUSINESS.
 
GENERAL
 
    NeoMagic Corporation (the "Company") was incorporated as a California
corporation in May 1993. The Company was subsequently reincorporated as a
Delaware corporation in February 1997. The Company's initial public offering
occurred in March 1997. The Company operates in one industry segment. NeoMagic
designs, develops and markets high-performance semiconductor solutions for sale
to original equipment manufacturers ("OEMs") of mobile computing products. To
date, all the Company's net sales have been derived from the sale of multimedia
accelerators to the notebook PC market.
 
    Multimedia applications require the storage, processing and display of
enormous streams of data. As a result, multimedia PCs have evolved to
incorporate higher capacity storage and system memory, faster microprocessors,
improved specialized multimedia accelerators, and higher quality displays.
However, due to the constraints imposed by the mobile form factor--the need for
low power consumption, small size, low weight, favorable thermal characteristics
and low cost, among others--the multimedia capabilities of notebook PCs have
historically lagged those of desktop computers. Until 1997, this limited the
effectiveness of multimedia applications in notebook PCs.
 
    To fully mobilize multimedia, the Company believed notebook PC manufacturers
required a new approach for developing multimedia accelerators which deliver
higher performance while minimizing power consumption, system size, weight,
complexity and cost.
 
    The Company, based on its knowledge of and experience in the industry,
believes it has developed the first commercially available high performance
silicon technology that integrates large DRAM memory with analog and logic
circuitry to provide multimedia solutions on a single chip. NeoMagic has
pioneered a new technology to provide multimedia semiconductor solutions for
notebook PCs, which overcomes the limitations of traditional architectures.
Using this technology, the Company has developed its first two product lines:
the MagicGraph128 and the MagicMedia256 families of pin-compatible, multimedia
(graphics, text and video) accelerator products incorporating a 128-bit and a
256-bit memory bus, respectively. These products provide state-of-the art
multimedia capability while decreasing power consumption, size, weight, system
design complexity and cost. The Company introduced its first MagicGraph128
product in March 1995, and is currently in production with the fourth generation
of this product family. In June 1998, the Company announced the industry's first
256-bit multimedia accelerator, the MagicMedia256AV. This chip integrates audio
and DVD video playback acceleration with high-performance PC graphics, into a
single twenty-one million transistor chip, with a peak internal bandwidth of 3.2
gigabytes per second. Through January 1999, the Company shipped over one million
units of the MagicMedia256AV.
 
    The Company believes that the dramatic growth of the Internet has expanded
its market opportunities, by bringing rich multimedia content to end-users at
their offices and in their homes. It is NeoMagic's strategy to participate in
multiple market opportunities driven by these trends towards multimedia,
mobility, and the Internet. To extend beyond the notebook arena, the Company
formed the Consumer Products Division and announced plans to enter into two new
market areas: digital cameras and Digital Versatile Disk (DVD) drive solutions.
The Company recently completed two acquisitions to bolster and accelerate its
new market activities. In February 1999, the Company announced the acquisition
of the Optical Drive Storage Group, located in Manchester, England, from Mitel
Semiconductor, and the acquisition of Associative Computers, Ltd., (ACL) located
in Raanana, Israel, from Robomatix. The Company's plan includes leveraging its
MagicWare embedded DRAM technology with the intellectual properties from these
recent acquisitions to deliver innovative solutions for the capture, storage,
and playback of multimedia content for a rich internet experience on mobile
platforms.
 
    NeoMagic has established strategic relationships with third-party
manufacturing partners to produce semiconductor wafers for the Company's
products. Pursuant to these strategic relationships, NeoMagic designs the
overall product, including the logic and analog circuitry, and the manufacturing
partners designs the DRAM modules, manufactures the wafers and performs memory
testing and repair. NeoMagic is focused on leveraging its core competencies in
logic, analog and memory integration, graphics/video,
<PAGE>
DVD, 3D and other multimedia technologies, driver and BIOS software, and power
management in its continued development of solutions that facilitate the
mobilization of multimedia applications.
 
PRODUCTS
 
    All of the Company's net sales in fiscal 1999 were from the sale of
multimedia accelerators to notebook PC OEMs, or to third-party subsystem
manufacturers who design and manufacture notebooks on behalf of the OEMs.
Virtually all of the world's largest notebook PC manufacturers have designed or
are designing notebook PCs to include NeoMagic products. NeoMagic products are
currently used in notebooks sold by Acer, Compaq, Dell, Fujitsu, Gateway,
Hewlett-Packard, Hitachi, IBM, Micron, Mitsubishi, NEC, Panasonic, Sharp,
Siemens, Sony, and Toshiba.
 
    The products in the MagicGraph128 and MagicMedia256 product families
integrate large DRAM with analog and logic circuitry on a single chip.
NeoMagic's products range from accelerators designed for notebook PCs that span
across all notebook categories including desktop replacement, mainstream, value-
oriented, ultra-portable, and entry level systems. The following table sets
forth information with respect to the Company's main products:

integrated audio controller into analog signals provided by the microphone or
needed by the speakers. When used together, the NeoMagic solution provides 3D
audio positioning enhancements and soft Wavetable synthesis. The MagicWave3DX
also provides additional features through its hardware compatibility with legacy
audio standards.
 
RESEARCH AND DEVELOPMENT
 
    The Company considers the timely development and introduction of new
products to be essential to maintaining its competitive position and
capitalizing on market opportunities. Research and development efforts focus on
the design of new products and the enhancement or redesign for cost reduction
purposes of existing products that will help to maintain or increase the
Company's participation in various product areas. At January 31, 1999, the
Company had approximately 139 employees engaged in research and development.
Research and development expenses in fiscal 1999, 1998 and 1997 were $31.8
million, $16.1 million and $8.6 million, respectively. The Company has made, and
intends to continue to make, significant investments in research and development
to remain competitive by developing new and enhanced products to serve its
identified markets. Research and development expenses are expected to increase
in absolute dollars in fiscal 2000. The development and successful introduction
of new products presents a variety of risks, and there can be no assurance that
these or other product development efforts will be completed at the time the
Company expects, or that new products will be accepted in the marketplace.
 
SALES AND MARKETING
 
    NeoMagic's sales and marketing strategy is an integral part of the Company's
effort to become the leading supplier of semiconductor solutions to the leading
manufacturers of mobile products. To meet customer requirements and achieve
design wins, the Company's sales and marketing personnel work closely with its
customers, business partners and key industry trend-setters to define product
features, performance, price, and market timing of new products. The Company
employs a sales force with a high level of technical expertise and product and
industry knowledge to support a lengthy and complex design win process.
Additionally, the Company employs a highly trained team of application engineers
to assist customers in designing, testing and qualifying system designs that
incorporate NeoMagic products. The Company believes that the depth and quality
of this design support are key to improving customers' time-to-market deliveries
and maintaining a high level of customer satisfaction, which encourages
customers to utilize subsequent generations of NeoMagic's products.
 
    In the United States, the Company sells its products to key customers
primarily through direct sales. In Japan, DIA Semicon acts as the Company's
sales representative. In Taiwan, Regulus acts as the Company's sales
representative, with support from the Company's Taiwan country manager. As of
January 31, 1999, NeoMagic employed 41 individuals in its sales, marketing and
support organizations, and maintained regional sales offices in California,
Texas, Hong Kong and Taiwan.
 
    In many cases, notebook PCs are designed and manufactured by third party
system manufacturers on behalf of the final brand-name OEM. NeoMagic focuses on
developing long-term customer relationships with both the system manufacturer
and the brand-name OEM. The Company believes that this approach increases the
likelihood for design wins, improves the overall quality of support, and enables
the timely release of customer products to market.
 
MANUFACTURING
 
    The Company's products require semiconductor wafers manufactured with
state-of-the-art fabrication equipment and technology. The Company's products
are designed to be manufactured in accordance with the DRAM partners' design
rules and manufacturing processes. Each DRAM partner has a design team dedicated
to NeoMagic product development. The DRAM partners design the DRAM product
modules
 
                                     Page 3
<PAGE>
and NeoMagic designs the overall product, including the analog and logic
circuitry. The DRAM partners then aid the Company in design verification prior
to production. The DRAM partners manufacture the wafers, perform memory testing
and repair, and sell the Company finished wafers, with pricing determined on a
quarterly basis.
 
    NeoMagic has strategic relationships with Mitsubishi Electric Corporation
("Mitsubishi Electric"), Toshiba Corporation ("Toshiba") and Infineon
Technologies ("Infineon"), formerly Siemens Aktiengesellschaft Semiconductor
Group ("Siemens"), to produce its semiconductor wafers. These relationships
enable the Company to concentrate its resources on product design and
development, where NeoMagic believes it has greater competitive advantages, and
to eliminate the high cost of owning and operating a semiconductor wafer
fabrication facility. The Company depends on these suppliers to allocate to the
Company a portion of their manufacturing capacity sufficient to meet the
Company's needs, to produce products of acceptable cost and quality and at
acceptable manufacturing yields, and to deliver those products to the Company on
a timely basis. A manufacturing disruption experienced by any of the Company's
manufacturing partners would have an adverse effect on the Company's business,
financial condition and results of operations. Furthermore, in the event that
the transition to the next generation of manufacturing technologies at one of
the Company's suppliers is unsuccessful, the Company's business, financial
condition and results of operations would be materially and adversely affected.
Additionally, there can be no assurances that any of the Company's manufacturing
partners will continue to devote resources to the production of the Company's
products or continue to advance the process design technologies on which the
manufacturing of the Company's products are based. The Company in the past has
experienced difficulties in some of these areas, and there can be no assurance
that in the future the Company will not experience supply-related difficulties,
which could have a material effect on the Company's business, financial
condition and results of operations.
 
    The Company uses other third-party subcontractors to perform assembly and
testing of the Company's products. The Company develops its own software and
hardware for product testing. The Company does not have long-term agreements
with any of these subcontractors. As a result of this reliance on third-party
subcontractors to assemble and test its products, the Company cannot directly
control product delivery schedules, which could lead to product shortages or
quality assurance problems that could increase the costs of manufacturing or
assembly of the Company's products. Due to the amount of time normally required
to qualify assembly and test subcontractors, if the Company is required to find
alternative subcontractors, shipments could be delayed significantly. Any
problems associated with the delivery, quality or cost of the assembly and test
of the Company's products could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
COMPETITION
 
    The market for multimedia accelerators for notebook PCs in which the Company
participates is intensely competitive and is characterized by rapid
technological change, evolving industry standards and declining average selling
prices. NeoMagic believes that the principal factors of competition in this
market are performance, price, features, power consumption, size and software
support. The ability of the Company to compete successfully in the rapidly
evolving notebook PC market depends on a number of factors including, success in
designing and subcontracting the manufacture of new products that implement new
technologies, product quality and reliability, price, the efficiency of
production, ramp up of production of the Company's products for particular
system manufacturers, end-user acceptance of the system manufacturers' products,
market acceptance of competitors' products and general economic conditions. The
Company's ability to compete in the future will also depend on its ability to
identify and ensure compliance with evolving industry standards. Unanticipated
changes in industry standards could render the Company's products incompatible
with products developed by major hardware manufacturers and software developers,
including Intel Corporation and Microsoft Corporation. The Company could be
required, as a result, to invest significant time and resources to redesign its
products or obtain license rights
 
                                     Page 4
<PAGE>
to technologies owned by third parties in order to ensure compliance with
relevant industry standards. There can be no assurance that the Company could
redesign its products or obtain the necessary third-party licenses within the
appropriate window of market demand. If the Company's products are not in
compliance with prevailing industry standards for a significant period of time,
the Company could miss crucial OEM design cycles, which could result in a
material adverse effect on the Company's business, financial condition and
results of operations. In addition, the Company's products are designed to
afford the notebook PC manufacturer significant advantages with respect to
product performance, power consumption and size. To the extent that other future
developments in notebook PC components or subassemblies incorporate one or more
of the advantages offered by the Company's products, the market demand for the
Company's products may be negatively impacted.
 
    NeoMagic competes with major domestic and international companies, some of
which have substantially greater financial and other resources than the Company
with which to pursue engineering, manufacturing, marketing and distribution of
their products. The Company's principal competitors include ATI Technologies
(ATI), Chips & Technologies, Inc. ("Chips & Technologies"- in January 1998,
Intel Corporation acquired Chips and Technologies) and Trident Microsystems,
Inc. ("Trident"). NeoMagic may also face increased competition from new entrants
into the notebook PC multimedia accelerator market including companies currently
selling products designed for desktop PCs. Some of the Company's competitors,
including Chips & Technologies and Trident, have announced or introduced
multimedia accelerator products that integrate large DRAM with analog and logic
circuitry on a single chip. Certain of the Company's competitors may offer
products with more functionality and / or higher processor speeds at the expense
of battery life and power consumption than the Company's product offerings.
These feature sets may be more competitive for certain applications than the
Company's products. Potential competition also could come from manufacturers
that integrate the multimedia accelerator with other systems components. For
example, Cyrix (acquired by National Semiconductor in July 1997) is in
production of an integrated microprocessor and graphics accelerator. Further,
several of the Company's competitors have announced plans to develop products
that integrate the multimedia accelerator with the core logic chip set. The
successful commercial introduction by competitors of products that integrate
large DRAM with analog and logic circuitry on a single chip, or that eliminate
the need for a separate multimedia accelerator in notebook PCs could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
    Some of the Company's current and potential competitors operate their own
manufacturing facilities. Since the Company does not operate its own
manufacturing facility and must make binding commitments to purchase products,
it may not be able to reduce its costs and cycle time or adjust its production
to meet changing demand as rapidly as companies that operate their own
facilities, which could have a material adverse effect on the Company's results
of operations.
 
INTELLECTUAL PROPERTY
 
    The Company relies in part on patents to protect its intellectual property.
In the United States, the Company has been issued ten patents, each covering
certain aspects of the design and architecture of the Company's multimedia
accelerators. The Company also acquired and/or licensed intellectual properties
in the areas of mixed signal analog design and array-based processing as part of
the February 1999 acquisitions of the Optical Drive Development Group and ACL.
Additionally, the Company and its newly acquired businesses have patent
applications pending. There can be no assurance that the Company's pending
patent applications, or any future applications will be approved. Further, there
can be no assurance that any issued patents will provide the Company with
significant intellectual property protection, competitive advantages, or will
not be challenged by third parties, or that the patents of others will not have
an adverse effect on the Company's ability to do business. In addition, there
can be no assurance that others will not independently develop similar products,
duplicate the Company's products or design around any patents that may be issued
to the Company.
 
                                     Page 5
<PAGE>
    The Company also relies on a combination of mask work protection,
trademarks, copyrights, trade secret laws, employee and third-party
nondisclosure agreements and licensing arrangements to protect its intellectual
property. Despite these efforts, there can be no assurance that others will not
independently develop substantially equivalent intellectual property or
otherwise gain access to the Company's trade secrets or intellectual property,
or disclose such intellectual property or trade secrets, or that the Company can
meaningfully protect its intellectual property. A failure by the Company to
meaningfully protect its intellectual property could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
    As a general matter, the semiconductor industry is characterized by
substantial litigation regarding patent and other intellectual property rights.
In December 1998, the Company filed a lawsuit in the United States District
Court for the District of Delaware against Trident Microsystems, Inc. The suit
alleges that Trident's embedded DRAM graphics accelerators infringe certain
patents held by the Company. In January 1999, Trident filed a counter claim
against the Company alleging an attempted monopolization in violation of
antitrust laws, arising from NeoMagic's filing of the patent infringement action
against Trident in December. The Company has filed for a summary motion to
dismiss the antitrust claim. There can be no assurance as to the results of the
request for summary motion, the patent infringement suit and the counter-suit
for antitrust filed by Trident.
 
    The Company in the past has been, and in the future may be, notified that it
may be infringing the intellectual property rights of third parties. For
example, in February 1997, Cirrus Logic Inc. ("Cirrus Logic") sent the Company
written notice asserting that the Company's MagicGraph128, MagicGraph128V and
MagicGraph128ZV products infringe six United States patents held by Cirrus
Logic. Since receiving the notice of alleged infringement, the Company has
advised Cirrus Logic that the Company does not believe that any of its products
infringe any claims of the patents. The Company also has undergone a
confidential external infringement review and has conducted its own internal
infringement review, and the Company continues to believe that the Cirrus Logic
infringement allegations are unfounded. However, there can be no assurances that
Cirrus Logic will not file a lawsuit against the Company or that the Company
would prevail in any such litigation. Any protracted litigation by Cirrus Logic
or the success of Cirrus Logic in any such litigation could have a material and
adverse effect on the Company's financial position or results of operations.
 
    Further, in February 1999, the Company was contacted by two of its customers
that they have been notified of potential infringement by a holder of three
United States patents and are requesting indemnification from NeoMagic. At this
time, the Company's counsel is in the preliminary stage of analyzing these
patents but has not reached a conclusion. The Company may have certain
indemnification obligations to customers with respect to the infringement of
third-party intellectual property rights by its products. There can be no
assurance that the Company's potential obligations to indemnify such customers
will not have a material adverse effect on the Company's business, financial
condition and results of operations. Further, there can be no assurances that
the Company or such customers would prevail in any patent litigation, or that
such customers will continue to purchase the Company's products while the
Company is under the threat of litigation.
 
    Any patent litigation, whether or not determined in the Company's favor or
settled by the Company, would at a minimum be costly and could divert the
efforts and attention of the Company's management and technical personnel from
productive tasks, which could have a material adverse effect on the Company's
business, financial condition and results of operations. There can be no
assurance that current or future infringement claims by third parties or claims
for indemnification by other customers or end users of the Company's products
resulting from infringement claims will not be asserted in the future or that
such assertions, if proven to be true, will not materially adversely affect the
Company's business, financial condition and results of operations. In the event
of any adverse ruling in any such matter, the Company could be required to pay
substantial damages, which could include treble damages, cease the
manufacturing, use and sale of infringing products, discontinue the use of
certain processes or to obtain a
 
                                     Page 6
<PAGE>
license under the intellectual property rights of the third party claiming
infringement. There can be no assurance, however, that a license would be
available on reasonable terms or at all. Any limitations on the Company's
ability to market its products, or delays and costs associated with redesigning
its products or payments of license fees to third parties, or any failure by the
Company to develop or license a substitute technology on commercially reasonable
terms could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
BACKLOG
 
    Sales of the Company's products are primarily made pursuant to standard
purchase orders that are cancelable without significant penalties. These
purchase orders are subject to price renegotiations and to changes in quantities
of products and delivery schedules in order to reflect changes in customers'
requirements and manufacturing availability. Also, many of the Company's
customers are moving to "just in time" relationships with their vendors, whereby
orders for product deliveries are not provided to the supplier until just prior
to the requested delivery. A large portion of the Company's sales are made
pursuant to short lead-time orders. In addition, the Company's actual shipments
depend on the manufacturing capacity of the Company's suppliers and the
availability of products from such suppliers. As a result of the foregoing
factors, the Company does not believe that backlog is a meaningful indicator of
future sales.
 
EMPLOYEES
 
    As of January 31, 1999, the Company employed a total of 234 full-time
employees, including 139 in research and development, 16 in customer service and
applications engineering, 25 in sales and marketing, 21 in manufacturing and 33
in finance and administration. The Company also employs, from time to time, a
number of temporary and part-time employees as well as consultants on a contract
basis. The Company's employees are not represented by a collective bargaining
organization, and the Company believes that its relations with its employees are
good.

ITEM 2. PROPERTIES
 
    The Company's corporate headquarters, which is also its principal
administrative, selling and marketing, customer service, applications
engineering and product development facility, is located in Santa Clara,
California and consists of approximately 90,000 square feet under leases which
expire on April 30, 2003. The Company leases offices in India, Hong Kong, Taiwan
and Texas under operating leases that expire at various times through September
2000. The Company believes its existing facilities are adequate for its current
needs, but that additional space for growth will be required in the future.
 
ITEM 3. LEGAL PROCEEDINGS
 
    In December 1998, the Company filed a lawsuit in the United States District
Court for the District of Delaware against Trident Microsystems, Inc.
("Trident"). The suit alleges that Trident's embedded DRAM graphics accelerators
infringe certain patents held by NeoMagic Corporation. In January 1999, Trident
filed a counter claim against the Company alleging an attempted monopolization
in violation of antitrust laws, arising from NeoMagic's filing of the patent
infringement action against Trident in December. The Company has filed for a
summary motion to dismiss the antitrust claim. There can be no assurance as to
the results of the request for summary motion, the patent infringement suit and
the counter-suit for antitrust filed by Trident.
 
    In February 1999, the Company was informed by two of its customers that they
have been notified of potential patent infringement by a holder of three United
States patents and are requesting indemnification from NeoMagic. At this time,
the Company's counsel is in the preliminary stage of analyzing these patents but
has not reached a conclusion. The Company may have certain indemnification
obligations to customers with respect to the infringement of third-party
intellectual property rights by its products. There can be no assurance that
NeoMagic's potential obligation to indemnify such customers will not have a
material adverse effect on the Company's business, financial condition and
results of operations. Further, there can be no assurances that the Company or
such customers would prevail in any patent litigation, or that such customers
will continue to purchase products from the Company while under threat of
litigation.
