 Business

Company Overview

We design, develop, market and license memory technologies used by the semiconductor industry and electronic product
manufacturers. We have developed a patented semiconductor memory technology, called 1T−SRAM, that offers a combination of
high density, low power consumption and high speed at performance and cost levels that other available memory technologies do not
match. We license this technology to companies that incorporate, or embed memory on complex integrated circuits, such as
system−on−chips (SoCs). We have also in the past sold memory chips based on our 1T−SRAM technologies, but in 2004, we ceased
actively selling them. We do not expect to make and sell memory chips in the future.

Using elements of our existing memory technology as a foundation, we completed development of the first memory chips
incorporating our 1T−SRAM technologies in the fourth quarter of 1998. We signed our first license agreement related to our
1T−SRAM technologies at the end of the fourth quarter of 1998 and recognized licensing revenue from our 1T−SRAM technologies
for the first time in the first quarter of 2000. Since then, we have introduced improved and enhanced versions of our technology, such
as 1T−SRAM−R, 1T−SRAM−M, and 1T−SRAM−Q.

We generate revenue from licensing our memory technologies, which revenue consists of licensing revenues, customization
services, maintenance and support fees and royalties. Royalty revenues are earned under each of our license agreements when our
licensees manufacture or sell products that incorporate any of our 1T−SRAM technologies and report the results to us. Generally, we
expect our total sales cycle, or the period from our initial discussion with a prospective licensee to our receipt of royalties from the
licensee’s use of our 1T−SRAM technologies, to run from 18 to 24 months after the commencement of the project. The portion of our
sales cycle from the initial discussion to the receipt of license fees may run from six to twelve months, depending on the complexity of
the proposed project and degree of customization required.

In 2005, we began delivering our new family of 1T−SRAM CLASSIC Memory Macro products to licensees. These macros are

silicon−proven, high−density solutions offering customers rapid memory block integration into their SoC designs. They are
pre−configured and require minimal additional customization and we believe they will enable us to increase our penetration of the
market for very dense, low power, high speed embedded memory applications.

Industry Background

Trends in the Semiconductor Industry

The personal computer, wireless communications, networking equipment and consumer electronics markets are characterized by

intensifying competition, rapid innovation, increasing performance requirements and continuing cost pressures. To manufacture
electronic products that achieve optimal performance and cost levels, semiconductor companies must produce integrated circuits that
offer higher performance, greater functionality and lower cost.

Two important measures of performance are speed and power consumption. Higher−speed integrated circuits allow electronic

products to operate faster, enabling the performance of more functions. Reducing the power consumption of integrated circuits
contributes to increased battery life and reduced heat and electro magnetic field (EMF) generation in electronic products. Reduced
power consumption also enables integrated circuit designers to overcome costly design hurdles, such as meeting the thermal
limitations of low−cost packaging materials.

In addition to offering high−performance products, semiconductor companies must produce integrated circuits that are cost
effective. High−density integrated circuits require less silicon, thus reducing their size and cost. Cost reductions also can be achieved
by simplifying the integrated circuit’s manufacturing process and improving the manufacturing yield.

To avoid the high cost of substantial redesign, semiconductor companies typically use technology that is scalable, which means it

can be readily incorporated into multiple generations of manufacturing process technologies. Process technology generations are
distinguished in terms of the dimension of the integrated circuit’s smallest topographical features, as measured in microns (one
millionth of a meter) or nanometers (one billionth of a meter). The semiconductor industry has continuously developed advanced
process technologies that enable the reduction of silicon area on integrated circuits and consequently lower costs. Today, the industry
is predominantly using 0.13−micron, 0.15−micron, and 90 nanometers (nm) manufacturing process technologies. However, new
designs are now being implemented in 65nm with even smaller manufacturing process technologies anticipated in the near future.

Importance of Integration

For decades, the semiconductor industry has continuously increased the value of integrated circuits by improving their density,
power consumption, speed and cost. The main driver for these improvements has been the success of shrinking the size of the basic
semiconductor building block, or transistor. Transistors have become small enough to make it economical to combine multiple
functions, such as microprocessors, graphics, memory, analog components and digital signal processors, on a SoC. Highly integrated
circuits such as SoCs often offer advantages in density, power consumption, speed and cost that cannot be matched using separate,
discrete integrated circuits. SoCs are essential for most electronic products, such as cellular phones, video game consoles, portable
media players, communication and networking equipment and internet appliances, to achieve increasing performance requirements at
a reasonable cost.

Importance of Embedded Memory

Historically, semiconductor companies implemented memory in separate integrated circuits. Rather than using separate memory
chips, many semiconductor companies today are embedding memory on highly integrated circuits in order to optimize performance
and power consumption. At the same time, the increasing sophistication of electronic products is driving a rapid increase in the
amount of memory required. The amount of area comprised of embedded memory on a SoC is continuing to grow due to increasing
complexity of applications requiring more data and program code and system price and size

5

constraints which dictate that more information be stored in local memories on the chip rather than in discrete memory chips.

The high cost of incorporating the memory component represents a major challenge to achieving high levels of integration. As

embedded memories account for an increasing percentage of the size of a highly integrated circuit, they are often the slowest or
limiting function in the circuit. Not only must integrated circuits contain a larger amount of embedded memory, this memory must be
dense enough to be economically attractive and must offer sufficiently high speed and low power consumption. In many applications,
embedded memory has become a crucial design consideration for determining the overall cost and performance of highly integrated
circuits and the growing number of electronic products in which they are incorporated.

Traditional SRAM and Embedded DRAM

The most common form of embedded memory today utilizes traditional static random access memory, or SRAM. This technology

is in the public domain and can be designed by any semiconductor company. Traditional SRAM has the following characteristics—

•  it can operate at the same high speeds as other functions of the integrated circuit;
•  it provides a simple and familiar interface that allows for quick design into an integrated circuit with less risk that the design

will not function according to specification; and

•  it utilizes the standard logic manufacturing process that is both economical and the most widely available.
As memory requirements increase, however, traditional SRAM becomes relatively more expensive compared to the total cost of

the integrated circuit. Specifically, traditional SRAM has the following drawbacks that can lead to higher cost—

•  it requires a substantial amount of silicon area because of its low density; and
•  it consumes a significant amount of power when operating at high speeds.
To overcome the density limitations of traditional SRAM, some SoC manufacturers have utilized embedded dynamic random

access memory, or embedded DRAM. While embedded DRAM is denser than traditional SRAM, it is dramatically slower.
Manufacturing embedded DRAM also requires additional process steps and results in lower yields, which translate into increased
manufacturing time and cost. Additionally, because of its complex interface requirements, embedded DRAM is more difficult to
incorporate on integrated circuits, leading to a higher risk of failure. As integrated circuit designers have experimented with embedded
DRAM, they have discovered that these limitations of embedded DRAM preclude its use in most applications. Therefore, traditional
SRAM continues to be the most widely used technology for embedded memory. One of the major challenges for the semiconductor
industry today is to find an embedded memory solution that combines high density, low power consumption, high speed and low cost.

Our Solution

Our innovative 1T−SRAM technologies provide major advantages over traditional SRAM in density, power consumption and
cost, thus making it more economical for designers to incorporate large amounts of embedded memory in their designs. In addition,
our 1T−SRAM technologies offer all the benefits of traditional SRAM, such as high speed, simple interface and ease of
manufacturability. Its core circuitry is already production proven in millions of memory chips and offers integrated circuit designers
the following characteristics compared to traditional SRAM:

Parameters
Density
Cost
Power
Speed

Typical Characteristics of 1T−SRAM technologies vs. traditional SRAM
Uses 50% to 75% less silicon for the same amount of memory
50% to 70% less cost for the same amount of memory
Can save up to 75% of the power when operating at the same speed
Can provide speeds equal to or greater than those offered by
traditional SRAM, especially for larger memory sizes

Our 1T−SRAM technologies can achieve these advantages while utilizing standard logic manufacturing processes and providing

the simple, standard SRAM interface that designers are accustomed to today.

High Density

Embedded memory utilizing our 1T−SRAM technologies is typically two to three times denser than traditional SRAM. Increased

density enables manufacturers of electronic products, such as cellular phones, video game consoles and digital cameras and
camcorders, to incorporate additional functionality into a single integrated circuit, resulting in overall cost savings. Semiconductor
designers can take advantage of the high density of our 1T−SRAM technologies and embed large quantities of high−performance
memory and other components that in the past might not have been feasible.

Low Power Consumption

Embedded memory utilizing our 1T−SRAM technologies can consume as little as one−quarter the power and generates less heat

than traditional SRAM when operating at the same speed. This feature facilitates longer battery life, reduces system level cooling
costs and enables reliable operation using lower−cost packaging.

High Speed

Embedded memory utilizing our 1T−SRAM technologies typically provides speeds equal to or greater than the speeds of

traditional SRAM, especially for larger memory sizes. Our 1T−SRAM memory designs can sustain random access cycle times of less
than three nanoseconds. In today’s 0.13−micron manufacturing process technology, our 1T−SRAM technologies can operate with a
random access frequency in excess of 400 megahertz for multi−megabit memory.

Manufacturing Process Independence

We have been able to implement our technology without requiring the manufacturer to make any significant changes to either

standard logic or alternative manufacturing processes. 1T−SRAM’s portability, or the ease with which it can be implemented in
different semiconductor manufacturing facilities, has been proven operational in the fabrication of chips at the world’s largest
independent foundries, including Taiwan Semiconductor Manufacturing Co., Ltd., or TSMC, United Microelectronics Corporation, or
UMC, Chartered Semiconductor Manufacturing Ltd., or Chartered, and Semiconductor Manufacturing International Corporation, or
SMIC. It has also been proven in the manufacturing processes of integrated

7

device manufacturers, or IDM’s, such as Fujitsu Limited and NEC Electronics. 1T−SRAM’s scalability, or the ease with which it can
be implemented in different generations of manufacturing processes, has already been demonstrated in the fabrication of chips in
0.25−micron, 0.18−micron, 0.15−micron, 0.13−micron and 90nm process generations, without extensive modifications. We expect
our technology to continue to scale readily to future process generations. This portability and scalability provides for wide availability,
inexpensive implementation and quick product time to market for our licensees.

Simplicity of Interface

Our 1T−SRAM technologies internal circuitry connects to the simple, standard SRAM interface that designers are accustomed to
today. Our use of this standard high−performance interface minimizes design time, thus optimizing time to market for our licensees.
This simple interface also helps minimize the risk that integrated circuit designs will not operate according to specifications.

Our Strategy

Our goal is to establish our 1T−SRAM technologies as the standard for all large embedded memories in SoC applications. We

intend to achieve this goal by licensing our technology on a non−exclusive and worldwide basis to foundries, integrated device
manufacturers, fabless semiconductor companies and electronic product manufacturers.

The following are integral aspects of our strategy.

Target Large and Growing Markets

We target the large and growing market for SoC applications requiring large embedded memories, which are in excess of one
megabyte, with our 1T−SRAM technologies that offer chip designers improved performance in embedded memories thus optimizing
the cost and performance of the SoC.

Although our 1T−SRAM technologies are applicable to many markets, we presently focus on the rapidly growing consumer
electronics and communications sectors. These sectors increasingly require embedded memory solutions with higher density, lower
power consumption, higher speeds and lower cost. We also will focus over the longer term on other markets that are projected to
achieve strong, long−term growth.

Work Closely with Semiconductor Companies and Foundries to Deliver Optimal Technology Solutions

We work closely with semiconductor companies and foundries to gain broad and detailed insight into their and their customers’

current and next−generation technology requirements. This insight helps us identify trends and focus our development efforts on
optimizing our technology solution, resulting in shorter product time to market and lower costs. We plan to continue to qualify and
license our technology with the leading IDM’s and foundries in order to provide a wide range of manufacturing choices for our
customers.

Extend our Technology Offerings

Our goal is to continue to enhance our 1T−SRAM technologies and increase our share of the embedded memory market. We will

continue to develop our technology in order to offer even higher−density, lower−power consumption, higher−speed and lower−cost
designs for our licensees. As such, we continue to invest heavily in research to develop more advanced memory technologies. Since
the introduction of 1T−SRAM in 1998, we have introduced and currently offer the following improvements to the 1T−SRAM
technology:

•  TEC® Error Correction Circuitry, which automatically corrects memory errors during operation, including soft errors caused by
high−energy particles, and eliminates the need for laser repair in manufacturing test. This is accomplished without adding silicon
area or cost. Introduced in November 2001, our TEC® Error Correction Circuitry has now become the standard within
1T−SRAM in most of our licensing activities.

•  Lower power version of 1T−SRAM memory macros, well−suited to particular applications requiring very low operating and

standby power, such as cell phone handsets, digital cameras, personal digital assistants and other consumer, wireless devices. We
introduced the 1T−SRAM Low−Power family of products in April 2001.

•  1T−SRAM with extended density memory (twice the density of the original version of our technology) and up to four times the

density of traditional SRAM. These products embed our advanced, folded capacitor 1T−Q bit cell. We introduced our
1T−Q−based products in December 2002.

In addition, we have developed new generations of our 1T−SRAM technologies, including the 90nm and 65nm manufacturing

process. We intend to continue to develop our technologies for future process generations such as 45nm and beyond.

Licensing and Distribution Strategy

We offer our technology on a non−exclusive and worldwide basis to semiconductor companies, electronic product manufacturers,

foundries, intellectual property companies and design companies through product development, technology licensing and joint
marketing relationships.

We license our technology to semiconductor companies who incorporate our technology into integrated circuits that they sell to

their customers. In addition, we engage in joint marketing activities with foundries, intellectual property companies and design
companies to promote our technology to a wide base of customers. These distribution channels have broadened the acceptance and
availability of our technology in the industry. As our technology becomes available through an increasing number of channels, we
believe it will be less likely that customers will have to alter their procurement practices in order to acquire our technology. We intend
to continue to expand significantly this base of strategic relationships to further proliferate our technology.

Project Licenses

We form product development and licensing relationships directly with semiconductor companies. In these relationships, the
prospective licensee’s implementation of our 1T−SRAM technologies typically includes customized development. Usually, these
relationships involve both engineering work to implement our technology in the specified product and licensing the technology for
manufacture and sale of the product. Although the precise terms contained in our 1T−SRAM macro development and license
agreements vary, every agreement provides for the payment of contract fees to us at the beginning of the contract and the joint
development of specifications and initial product design and engineering. Contract fees include licensing fees, development fees for
customizations based on the achievement of specified

9

Source: MoSys, Inc., 10−K, March 13, 2007

development milestones and royalties. The vast majority of our contracts allow billing between milestones based on work performed.
If we perform the contracted services, usually the licensee is obligated to pay the license fees even if the licensee cancels the project
prior to completion. The agreements often also provide for the payment of additional contract fees if we provide engineering or
manufacturing support services related to the manufacture of the product. Provisions in all of our license agreements require the
payment of royalties to us based on the future sale or manufacture of products utilizing our 1T−SRAM technologies. Generally, our
licenses grant rights on a non−exclusive, non−transferable basis, limited to the use of our technology as modified for the project
covered by the license agreement. Our license agreements generally have a fixed five−year term and are subject to renewal. Each new
project requires a separate agreement or an addendum to modify an existing agreement.

We have license agreements with many companies, including, but not limited to, Agere Systems, Inc., Agilent Technologies,
Analog Devices, Inc., Broadcom Corporation, eSilicon Corporation, Fujitsu Limited, Hitachi, Ltd., Kawasaki Micoroelectronics, Inc.,
LG Electronics, Inc., LSI Logic Corporation, Marvell Semiconductor, Inc., Matsushita Communication Industrial Co., Ltd., National
Semiconductor Corporation, NEC Electronics Corporation, Nexuschips Co. Ltd., Open−Silicon, Inc., Philips Semiconductors, Inc.,
Pixelworks, Inc., Pixim, Inc., Progate Group Corporation, SMIC, Sanyo Electric Co., Ltd., Sony Corporation, TSMC, UMC, Via
Technologies, Inc., and Yamaha Corporation.

Joint Marketing Arrangements

We have formed joint marketing relationships with dedicated foundries such as TSMC, UMC, Chartered and SMIC. These
foundries have cooperated with us to prove the manufacturability of integrated circuits utilizing our 1T−SRAM technologies in their
particular manufacturing process. Once manufacturability has been proven, the foundries can then offer their manufacturing services
to our licensees, and their integrated circuit device customers can fabricate integrated circuits incorporating our 1T−SRAM
technologies.

Design Licenses

We offer directly to our licensees customized 1T−SRAM memory designs to meet their specific design parameters. We also offer

a variety of options for optimizing the design specification in order to improve performance and cost effectiveness.

Companies also can license standard 1T−SRAM off−the−shelf memory designs from us, known as CLASSIC Macros. These

readily available pre−qualified standard memory designs can assist the licensee in getting its SoC quickly to market.

Technology Licenses

We also offer our technology to semiconductor companies and foundries through 1T−SRAM technology license agreements,
under which we grant the licensee the additional right to create and modify 1T−SRAM designs to offer to its own customers. The
contract fees associated with these arrangements require the licensee to pay us to port our technology to its manufacturing process and
develop a template design that the licensee will be able to use to generate future designs. These agreements also may obligate the
licensee to pay contract fees upon the achievement of specified development milestones and may provide for the payment of
additional contract fees for engineering or manufacturing support services. Royalties are payable based on the future sale or
manufacture of products utilizing our 1T−SRAM technologies. The licenses are non−exclusive and non−transferable and authorize the
licensee to modify designs for its customers from the template design that we provide under the agreement. Typically, the template
design applies only to a specified manufacturing process generation. The licensee may add future process generations to the license
agreement for additional contract fees.

Technology

Our innovative 1T−SRAM technologies include many new and proprietary features. These technologies combine the high−density

advantages of DRAM with the high performance and utility of SRAM. Underlying this technology are several distinct pieces of
proprietary technology.

Single−Transistor Memory Storage Cell

The high density of our 1T−SRAM technologies stems from the use of a single−transistor, or 1T, which is similar to DRAM, with

a storage cell for each bit of information. Our 1T storage cell using one transistor and one capacitor represents a very significant
improvement in density over the six−transistor storage cells used by traditional SRAM.

The following diagrams, drawn to scale, but not to actual size, are electrical schematics of the traditional SRAM storage cell and
our 1T−SRAM storage cell. The comparison of the two diagrams illustrates the small size and reduced complexity of the 1T−SRAM
storage cell. This results in significant cost savings because less silicon space is required by 1T−SRAM storage cells.

11

MultiBank Technology

The high speed and low power consumption of 1T−SRAM are enabled by our MultiBank technology, as illustrated below. This
technology efficiently partitions the memory into many, typically hundreds, of fast, small sub−blocks of memory, or banks, that can
operate independently over high−speed data buses. Only one small bank containing the required memory data must be active for each
access to the memory. Therefore, the remaining banks can stay in a low−power, standby mode, reducing the overall power
consumption of the memory.

Pipelined Self−timed Access

The easy to use standard SRAM interface of 1T−SRAM technologies is enabled by our innovative and proprietary circuit designs,

generating all the necessary dynamic memory array operation timing signals transparently to user’s application.

Refresh Management Circuitry

Refresh operations required to ensure data is maintained to a minimum level in dynamic cells may be performed transparently to a

user’s application, allowing designers to fully disregard any of the traditional requirements of dynamic cell arrays.

Leakage Suppression Circuitry

Our unique patented architecture, circuits and proprietary design techniques that manage process leakage allow MoSys 1T−SRAM

technologies to be manufactured on any complementary metal—oxide—semiconductor (CMOS) process, including generic
application−specific integrated circuit (ASIC) processes, thus removing the need for complicated embedded memory process
development.

Source: MoSys, Inc., 10−K, March 13, 2007

TEC® Error Correction Circuitry

We offer our 1T−SRAM technologies with embedded error correction circuitry for higher reliability and quality. This circuitry
automatically corrects memory errors during operation, including soft errors caused by high−energy particles, and eliminates the need
for laser repair in manufacturing test. This is accomplished without adding any additional silicon area or cost. The TEC® Error
Correction Circuitry is currently incorporated into all of our designs.

1T−Q® Folded Area Capacitor (FAC)

Using an innovative capacitor technology called Folded Area Capacitor (FAC), we can provide our licensees with a very

high−density memory solution. Requiring only two additional non−critical masks during the manufacturing process, with
1T−Q® Folded Area Capacitor our 1T−SRAM products can achieve densities up to four times that of traditional SRAM and twice the
density of the original version of our technology.

Advanced Manufacturing Processes

We have continued to implement our 1T−SRAM technologies on advanced generations of manufacturing processes. As a result,

our licensees are able to implement integrated circuits incorporating 1T−SRAM embedded memories on the highest performance
manufacturing processes available. The chart below illustrates a sampling of test chips we have made for initially implementing and
verifying 1T−SRAM technologies on the latest generations of manufacturing processes nodes. The processes with the smaller micron

Research and Development

Our ability to compete in the future depends on improving our technology to meet the market’s increasing demand for higher
performance and lower cost requirements. We have assembled a team of highly skilled engineers whose activities are focused on
developing even higher−density, lower−power consumption, higher−speed and lower−cost 1T−SRAM designs. We expect to continue
to focus our research and development efforts on extending our 1T−SRAM technologies to the 65nm process geometry and
developing new memory technologies, such as a flash memory version of our 1T−SRAM technology. We also intend to continue our
focus on porting our technology to additional semiconductor manufacturing facilities and scaling our technology to new generations of
manufacturing process technologies.

As of December 31, 2006, we employed 56 engineers, representing 70% of our employees, with specific expertise in circuit

design, layout and a variety of manufacturing processes. Effective November 10, 2004, we closed the ATMOS’ research and
development facility and terminated the employment of approximately 20 employees of ATMOS. We have a design center in Seoul,
South Korea where 11 of our engineers reside. For the years ended December 31, 2006, 2005, and 2004, research and development
expenditures totaled approximately $8.2 million, $5.8 million, and $8.1 million, respectively.

Sales and Marketing

As of December 31, 2006, we had 13 sales and marketing personnel, representing 16% of our employees, managing our licensing

activities. We have 10 sales and marketing personnel in the United States who are responsible for licensing activities in North
America, Asia and Europe. Two sales personnel

13

are located in Yokohama, Japan and one is located in Seoul, South Korea. The sales personnel manage the negotiation of license
agreements, provide technical support during the sales cycle to licensees and administer the contracts. Effective September 30, 2006,
we closed our office in Sophia−Antipolis, France and terminated two sales personnel there.

As we have multiple sales channels through our relationships with semiconductor companies, foundries, intellectual property
companies and design companies, we do not believe that we require a large internal sales force. Our marketing and promotional
activities include participation in industry trade shows, distribution of collateral marketing material, publication of articles in trade
journals and publicizing our licensing activities and technology achievements. We also provide presentations and working sessions
with the senior technical and business staff of prospective customers.

Intellectual Property

We regard our patents, copyrights, trademarks, trade secrets and similar intellectual property as critical to our success, and rely on

a combination of patent, trademark, copyright, and trade secret laws to protect our proprietary rights. As of December 31, 2006, we
held 82 U.S. patents on various aspects of our technology, with expiration dates ranging from 2011 to 2023. These 82 patents include
claims relating to multibank partitioning, 1T−SRAM internal operation and circuit techniques, high−speed operation techniques,
1T−SRAM refresh management techniques and the interface of embedded 1T−SRAM storage cells in logic processes. We currently
have 15 pending U.S. patent applications for which we have not yet received any notices of allowance. We also hold 52 foreign
patents with expiration dates ranging from 2012 to 2022, and we have 20 pending foreign patent applications. There can be no
assurance that others will not independently develop similar or competing technology or design around any patents that may be issued
to us, or that we will be able to enforce our patents against infringement.

The semiconductor industry is characterized by frequent litigation regarding patent and other intellectual property rights. Our
licensees or we might, from time to time, receive notice of claims that we have infringed patents or other intellectual property rights
owned by others. Our successful protection of our patents and other intellectual property rights are subject to a number of factors,
particularly those described in Part I, Item 1A. “Risk Factors.”

Competition

In order to remain competitive, we believe we must continue to provide higher−density, lower−power−consumption, higher−speed

and lower−cost technology solutions to the semiconductor industry and electronic product manufacturers. We believe that the
principal competitive factors in our industry are—

•  density and cost;
•  power consumption;
•  speed;
•  portability to different manufacturing processes;
•  scalability to different manufacturing process generations;
•  reliability and low manufacturing costs;
•  interface requirements;
•  the ease with which technology can be customized for and incorporated into customers’ products; and
•  level of technical support provided.

14

Source: MoSys, Inc., 10−K, March 13, 2007

We believe that our 1T−SRAM technologies offer a high degree of overall performance improvement over traditional SRAM. We

have designed the circuitry of our 1T−SRAM technologies so that our licensees can manufacture it in standard logic process, as well
as other widely used embedded memory processes. Semiconductor companies may satisfy their embedded memory needs through
traditional SRAM and embedded DRAM, however. Traditional SRAM relies on publicly available process technology and circuit
designs, which semiconductor companies can build internally or acquire through a license from a third party provider, without paying
a royalty to us. This is currently the preferred choice for embedded memory solutions in SoCs requiring less density. Companies
providing traditional SRAM embedded memories include ARM Holdings PLC and Virage Logic. Embedded DRAM is primarily
offered by current or former DRAM suppliers, who utilize their own manufacturing process to compete in the semiconductor foundry
business. Suppliers of embedded DRAM include substantial competitors such as Toshiba Ltd. and IBM, among others. Although each
of these two embedded DRAM suppliers has experienced some success in obtaining new customers for its technology, we believe that
many semiconductor companies using embedded memory may prefer to license our technology instead of implementing either of
these alternatives because of 1T−SRAM’s overall advantages.

Not all embedded memory applications benefit sufficiently from technological advantages offered by our 1T−SRAM technologies

to justify the increased cost to the licensee, however. Our licensees and prospective licensees can meet their current needs for
embedded memory using other memory solutions with different cost and performance parameters. For example, our technologies are
not suitable for replacing lower−cost traditional DRAM memory chips if higher access speed is unnecessary. In addition, alternative
solutions may be more cost−effective for memory block sizes of less than 1 megabit, or applications in which the embedded memory
portion is less than 20% of the total chip area.

Moreover, some companies assess greater uncertainty and risk in relying on our newly established 1T−SRAM technologies. As a

result, our ability to compete effectively may be limited because such companies may prefer to use more established traditional
memory solutions that are freely available without a license.

Employees

As of December 31, 2006, we had 80 full−time employees, consisting of 56 in research and development and engineering, 13 in
sales and marketing and 11 in finance and administration. We believe our future success depends, in part, on our ability to continue to
attract and retain qualified technical and management personnel, particularly highly skilled design engineers involved in new product
development, for whom competition is intense. Our employees are not represented by any collective bargaining unit, and we have not
experienced any work stoppage. We believe that our employee relations are good.

Item 1A.

 Risk Factors

If any of the following risks actually occur, our business, results of operations and financial condition could suffer significantly.

Our success depends upon the semiconductor market’s acceptance of our 1T−SRAM technologies.

The future prospects of our business depend on the acceptance by our target markets of our 1T−SRAM technologies for embedded

memory applications and any future technology we might develop. We have not achieved substantial or rapid growth in 1T−SRAM
technology licensing revenue from 2003−2006 and cannot be assured of realizing such growth in the future. Our technology is
intended to allow our licensees to develop embedded memory integrated circuits to replace other embedded memory technology with
different cost and performance parameters. Our 1T−SRAM technologies utilize fundamentally different internal circuitry that is not
widely known in the semiconductor industry. Therefore, one of our principal challenges, which we might fail to meet, is to convince a
substantial percentage of SoC designers to adopt our technology instead of other memory solutions, which may have proven effective
in their products. Failure to meet this challenge is likely to adversely affect our revenues, net income and cash flows and depress the
trading price of our common stock.

An important part of our strategy to gain market acceptance is to penetrate new markets by targeting market leaders as licensees of

our technology. This strategy is designed to encourage other participants in those markets to follow these leaders in adopting our
technology. If a high−profile industry participant adopts our technology for one or more of its products but fails to achieve success
with those products, or is unable to successfully implement our technology, other industry participants’ perception of our technology
could be harmed. Any such event could reduce the number of future licenses of our technology. Likewise, if a market leader were to
adopt and achieve success with a competing technology, our reputation and licensing program could be harmed.

Our lengthy licensing cycle and our licensees’ lengthy product development cycles make the operating results of our licensing
business difficult to predict.

We anticipate difficulty in accurately predicting the timing and amounts of revenue generated from licensing our 1T−SRAM
technologies. The establishment of a business relationship with a potential licensee is a lengthy process, generally taking from three to
nine months, and sometimes longer during slower periods in our industry. Following the establishment of the relationship, the
negotiation of licensing terms can be time−consuming, and a potential licensee may require an extended evaluation and testing period.
Once a license agreement has been executed, the timing and amount of licensing and royalty revenue from our licensing business
remain difficult to predict. The completion of the licensee’s development projects and the commencement of production are subject to
the licensee’s efforts, development risks and other factors outside our control. Our royalty revenue will depend on such factors as
success of the licensee’s project, the licensee’s production and shipment volumes, the timing of product shipments and when the
licensee reports to us the manufacture or sale of products that include our 1T−SRAM technologies. All of these factors will prevent us
from making predictions of revenue with any certainty and could cause us to experience substantial period−to−period fluctuations in
operating results.

17

Source: MoSys, Inc., 10−K, March 13, 2007

None of our licensees are under any obligation to incorporate our technology in any present or future product or to pursue the
manufacture or sale of any product incorporating our technology. A licensee’s decision to complete a project or manufacture a product
is subject to changing economic, marketing or strategic factors. The long development cycle of a licensee’s products increases the risk
that these factors will cause the licensee to change its plans. In the past, some of our licensees have discontinued development of
products incorporating our technology. Although in most cases their decisions were based on factors unrelated to our technology, it is
unlikely that we will receive royalties in connection with those products. We expect that occasionally our licensees will discontinue a
product line or cancel a product introduction, which could adversely affect our future operating results and business.

If the market for SoC integrated circuits does not expand, our business will suffer.

Our ability to achieve sustained revenue growth and profitability in the future will depend on the continued development of the

market for SoC integrated circuits, particularly those requiring embedded memory sizes of one megabit or more. In addition, our
ability to achieve design wins with customers is dependent upon the growth of embedded memories required in SoCs. SoCs are
characterized by rapid technological change and competition from an increasing number of alternate design strategies such as
combining multiple integrated circuits to create a System−on−a−Package.

We cannot be certain that the market for SoCs will continue to develop or grow at a rate sufficient to support our business, or that

if such growth does occur, that it will lead to significant growth in our business. SoC providers depend on the demand for products
requiring SoCs, such as cellular phones, game consoles, PDAs, digital cameras, DVD players and digital media players to name a few.
The demand for such products is uncertain and difficult to predict and depends on factors beyond our control. If the market fails to
grow or develops more slowly than expected, our business will suffer.

The semiconductor industry is cyclical in nature and subject to periodic downturns, which can negatively affect our revenue.

The semiconductor industry is cyclical and has experienced pronounced downturns for sustained periods of up to several years. To
respond to any downturn, many semiconductor manufacturers and their customers will slow their research and development activities,
cancel or delay new product developments, reduce their workforces and inventories and take a cautious approach to acquiring new
equipment and technologies. As a result, our business has been in the past and could be adversely affected in the future by an industry
downturn, which could negatively impact our future revenue and profitability. Also, the cyclical nature of the semiconductor industry
may cause our operating results to fluctuate significantly from year−to−year, which may tend to increase the volatility of the price of
our common stock.

We might be unable to deliver our customized memory technology within an agreed technical specification in the time frame
demanded by our licensees, which could damage our reputation, harm our ability to attract future licensees and adversely
impact operating results.

Many of our licenses require us to deliver a customized 1T−SRAM memory block or several blocks, within an agreed technical

specification by a certain delivery timetable. This requires us to furnish a unique design for each customer, which can make the
development schedule difficult to predict and involves extensive interaction with our customers’ engineers. From time to time, we
experience delays in delivering our customized memory technology that meets the agreed technical specifications, which can result
from slower engineering progress than we originally anticipated or there might be factors outside of our control, such as the
customer’s delay in completing verification of the customer’s chip. Such delays may affect the timing of recognition of revenues from
a particular project and can adversely affect our operating results.

In addition, any failure to meet our customers’ timetables, as well as the agreed upon technical specifications of our customized

memory technology could lead to the failure to collect, or a delay in

18

Source: MoSys, Inc., 10−K, March 13, 2007

collecting royalties and licensing fee payments from our licensees, damage our reputation in the industry, harm our ability to attract
new licensees and negatively impact our operating results. Furthermore, a customer may assert that we are responsible for delays and
cost overruns and demand reimbursement for some of its costs, which we may elect to reimburse in whole or in part in order to
address the customer’s concerns. For example, in 2004, we reduced revenue by $450,000 for a reimbursement to a customer for excess
verification costs incurred by the customer. In 2005, we also settled with one of our licensees for the amount of $375,000 related to a
claim made for excess verification costs incurred by the licensee. In 2006, no reimbursement of licensee costs was incurred.

Our business model relies on royalties as a key component in the licensing of our technologies, and if we fail to realize expected
royalties our operating results will suffer.

We believe that our long−term success is substantially dependent on the receipt of future royalties. Royalty payments owed to us
are calculated based on factors such as our licensees’ selling prices, wafer production, and other variables as provided in each license
agreement. The amount of royalties we will receive depends on the licensees’ business success, production volumes and other factors
beyond our control. This exposes our business model to risks that we cannot minimize directly and may result in significant
fluctuations in our royalty revenue and operating results from quarter−to−quarter. We cannot be certain that our business strategy will
be successful in expanding the number of licensees, nor can we be certain that we will receive significant royalty revenue in the future.

Our revenue has been highly concentrated among a small number of licensees and customers, and our results of operations
could be harmed if we lose and fail to replace this revenue.

Our overall revenue has been highly concentrated, with a few customers accounting for a significant percentage of our total
revenue. For the year ended December 31, 2006, our two largest customers, NEC and Fujitsu represented 27% and 25% of total
revenue, respectively. For the year ended December 31, 2005, our two largest customers, NEC and Fujitsu represented 35% and 17%
of total revenue, respectively. For the year ended December 31, 2004, our three largest customers NEC, Fujitsu and Marvell
represented 19%, 17% and 11% of total revenue, respectively. We expect that a relatively small number of licensees will continue to
account for a substantial portion of our revenue for the foreseeable future.

Our royalty revenue also has been highly concentrated among a few licensees, and we expect this trend to continue for the

foreseeable future. In particular, a substantial portion of our licensing and royalty revenue in 2006, 2005 and 2004 has come from the
licenses for integrated circuits used by Nintendo. Royalties earned from the production of Nintendo gaming devices incorporating our
1T−SRAM technology represented 16%, 14%, and 15% of total revenue in the 2006, 2005 and 2004, respectively. Nintendo faces
intense competitive pressure in the video game market, which is characterized by extreme volatility, costly new product introductions
and rapidly shifting consumer preferences, and we cannot assure you that Nintendo’s sales of products incorporating our technology
will increase beyond prior or current levels.

As a result of this revenue concentration, our results of operations could be impaired by the decision of a single key licensee or
customer to cease using our technology or products or by a decline in the number of products that incorporate our technology that are
sold by a single licensee or customer or by a small group of licensees or customers.

Our revenue concentration may also pose credit risks, which could negatively affect our cash flow and financial condition.

We might also face credit risks associated with the concentration of our revenue among a small number of licensees and

customers. As of December 31, 2006, one customer represented 89% of total

19

Source: MoSys, Inc., 10−K, March 13, 2007

trade receivables. Although trade receivables from this customer were subsequently collected, our failure to collect receivables from
any customer that represents a large percentage of receivables on a timely basis, or at all, could adversely affect our cash flow or
results of operations and might cause our stock price to fall.

Anything that negatively affects the businesses of our licensees could negatively impact our revenue.

The timing and level of our licensing and royalty revenues are dependent on our licensees and the business environment in which

they operate. Licensing and royalty revenue are the largest source of our revenues; anything that negatively affects a significant
licensee or group of licensees could negatively affect our results of operations and financial condition. Many issues beyond our control
influence the success of our licensees, including, for example, the highly competitive environment in which they operate, the strength
of the markets for their products, their engineering capabilities and their financial and other resources.

Likewise, we have no control over the product development, pricing and marketing strategies of our licensees, which directly
affect the licensing of our technology and corresponding future royalties payable to us from our licensees. Our royalty revenues are
subject to our licensees’ ability to market, produce and ship products incorporating our technology. A decline in sales of our licensees’
royalty−generating products for any reason would reduce our royalty revenue. In addition, seasonal and other fluctuations in demand
for our licensees’ products could cause our operating results to fluctuate, which could cause our stock price to fall.

We rely on semiconductor foundries to assist us in attracting potential licensees, and a loss or failure of these relationships
could inhibit our growth and reduce our revenue.

Part of our marketing strategy relies upon our relationships and agreements with semiconductor foundries, such as TSMC, UMC,

Chartered, and SMIC among others. These foundries have existing relationships, and continually seek new relationships, with
companies in the markets we target, and they have agreed to utilize these relationships to introduce our technology to potential
licensees. If we fail to maintain and expand our current relationships with these foundries, we might fail to achieve anticipated growth.
Our relationship with these foundries is not exclusive, and they are free to promote or develop other embedded memory technologies,
including their own. The foundries’ promotions of alternative technologies reduce the size of our potential market and may adversely
affect our revenues and operating results.

Additionally, we rely on third−party foundries to manufacture our silicon test chips, to provide references to their customers and to

assist us in the focus of our research and development activities. If we are unable to maintain our existing relationships with these
foundries or enter into new relationships with other foundries, we will be unable to verify our technologies for their manufacturing
processes and our ability to develop new technologies will be hampered. We would then be unable to license our intellectual property
to fabless semiconductor companies that use these foundries to manufacture their silicon chips, which is a significant source of our
revenues.

Our embedded memory technology is unique and the occurrence of manufacturing difficulties or low production yields, if not
corrected, could hinder market acceptance of our technology and reduce future revenue.

Complex technologies like ours could be adversely affected by difficulties in adapting our 1T−SRAM technologies to our

licensees’ product designs or to the manufacturing process technology of a particular foundry or semiconductor manufacturer. Some
of our customers have experienced lower than expected

20

Source: MoSys, Inc., 10−K, March 13, 2007

yields when initially integrating our design into their SoC. We work closely with our customers to resolve any design or process issues
in order to achieve the optimum production yield.

Any decrease in manufacturing yields of integrated circuits utilizing our technology could impede the acceptance of our

technology in the industry. The discovery of defects or problems regarding the reliability, quality or compatibility of our technology
could require significant expenditures and resources to fix, significantly delay or hinder market acceptance of our technology, reduce
anticipated revenues and damage our reputation.

Our failure to compete effectively in the market for embedded memory technology could reduce our revenue.

There exists significant competition in the market for embedded memory technologies. Our licensees and prospective licensees
can meet their need for embedded memory by using traditional memory solutions with different cost and performance parameters,
which they may internally develop or acquire from third−party vendors. In the recent years, the demand for applications for which our
1T−SRAM technologies provide distinct advantages has not experienced significant growth. If alternative technologies are developed
that provide comparable system performance at lower cost than our 1T−SRAM technologies for certain applications and/or do not
require the payment of comparable royalties, or if the industry generally demonstrates a preference for applications for which our
1T−SRAM technologies do not offer significant advantages, our ability to realize revenue from our 1T−SRAM technologies could be
impaired.

We might be challenged by competitive developers of alternative technologies who are more established, benefit from greater
market recognition and have substantially greater financial, development, manufacturing and marketing resources than we have. These
advantages might permit these developers to respond more quickly to new or emerging technologies and changes in licensee
requirements. We cannot assure you that future competition will not have a material adverse effect on the adoption of our technology
and our market penetration.

Our failure to continue to enhance our technology or develop new technology on a timely basis could diminish our ability to
attract and retain licensees and product customers.

The existing and potential markets for memory products and technology are characterized by ever increasing performance

requirements, evolving industry standards, rapid technological change and product obsolescence. These characteristics lead to frequent
new product and technology introductions and enhancements, shorter product life cycles and changes in consumer demands. In order
to attain and maintain a significant position in the market, we will need to continue to enhance our technology in anticipation of these
market trends.

In addition, the semiconductor industry might adopt or develop a completely different approach to utilizing memory for many
applications, which could render our existing technology unmarketable or obsolete. We might not be able to successfully develop new
technology, or adapt our existing technology, to comply with these innovative standards.

Our future performance depends on a number of factors, including our ability to—
•  identify target markets and relevant emerging technological trends, including new standards and protocols;
•  develop and maintain competitive technology by improving performance and adding innovative features that differentiate our

technology from alternative technologies;

•  enable the incorporation of enhanced technology in our licensees’ and customers’ products on a timely basis and at competitive

prices;

21

Source: MoSys, Inc., 10−K, March 13, 2007

•  implement our technology at future manufacturing process generations; and
•  respond effectively to new technological developments or new product introductions by others.
Since its introduction in 1998, we have introduced enhancements to our 1T−SRAM technology designed to meet market

requirements. However, we cannot assure you that the design and introduction schedules of any additions and enhancements to our
existing and future technology will be met, that this technology will achieve market acceptance or that we will be able to license this
technology on terms that are favorable to us. Our failure to develop future technology that achieves market acceptance could harm our
competitive position and impede our future growth.

Any claim that our products or technology infringe third−party intellectual property rights could increase our costs of
operation and distract management and could result in expensive settlement costs or the discontinuance of our technology
licensing or product offerings. In addition, we may incur substantial litigation expense, which would adversely affect our
profitability.

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights or positions, which

has resulted in often protracted and expensive litigation. For example, on March 31, 2004, we were sued by UniRAM
Technology, Inc. in United States District Court for the Northern District of California based on claims of patent infringement and
misappropriation of trade secrets that were allegedly disclosed by UniRAM to TSMC, which allegedly improperly provided them to
us. In October 2006, we settled this litigation with a payment of $2.4 million to UniRAM, which we paid in full in the fourth quarter
of 2006. Since the inception of that lawsuit, our total expenses related to it were $4.0 million. Our licensees or we might, from time to
time, receive notice of claims that we have infringed patents or other intellectual property rights owned by others. Litigation against
us, particularly patent litigation such as the UniRAM suit, can result in significant expense and divert the efforts of our technical and
management personnel, whether or not the litigation has merit or results in a determination adverse to us.

Royalty amounts owed to us might be difficult to verify, and we might find it difficult, expensive and time−consuming to
enforce our license agreements.

The standard terms of our license agreements require our licensees to document the manufacture and sale of products that

incorporate our technology and generally report this data to us after the end of each quarter. Though our standard license terms give us
the right to audit the books and records of any licensee to attempt to verify the information provided to us in these reports, an audit of
a licensee’s records can be expensive and time consuming, and potentially detrimental to the business relationship. A failure to fully
enforce the royalty provisions of our license agreements could cause our revenue to decrease and impede our ability to maintain
profitability.

We might not be able to protect and enforce our intellectual property rights, which could impair our ability to compete and
reduce the value of our technology.

Our technology is complex and is intended for use in complicated integrated circuits. A very large number of new and existing

products utilize embedded memory, and a large number of companies manufacture and market these products. Because of these
factors, policing the unauthorized use of our intellectual property is difficult and expensive. We cannot be certain that we will be able
to detect unauthorized use of our technology or prevent other parties from designing and marketing unauthorized products based on
our technology. In the event we identify any past or present infringement of our patents, copyrights or trademarks, or any violation of
our trade secrets, confidentiality procedures or licensing agreements, we cannot assure you that the steps taken by us to protect our
proprietary information will be adequate to prevent misappropriation of our technology. Our inability to protect adequately our

intellectual property would reduce significantly the barriers of entry for directly competing technologies and could reduce the value of
our technology. Furthermore, we might initiate claims or litigation against third parties for infringement of our proprietary rights or to
establish the validity of our proprietary rights. Litigation by us could result in significant expense and divert the efforts of our
technical and management personnel, whether or not such litigation results in a determination favorable to us.

Our existing patents might not provide us with sufficient protection of our intellectual property, and our patent applications
might not result in the issuance of patents, either of which could reduce the value of our core technology and harm our
business.

We rely on a combination of patents, trademarks, copyrights, trade secret laws and confidentiality procedures to protect our
intellectual property rights. As of December 31, 2006, we held 82 patents in the United States, which expire at various times from
2011 to 2023, and 52 corresponding foreign patents. In addition, as of December 31, 2006, we had 15 patent applications pending in
the United States and 20 pending foreign application, and we have not received any notices of allowance with respect to these
applications. We cannot be sure that any patents will issue from any of our pending applications or that any claims allowed from
pending applications will be of sufficient scope or strength, or issued in all countries where our products can be sold, to provide
meaningful protection or any commercial advantage to us. Also, competitors might be able to design around our patents. Failure of our
patents or patent applications to provide meaningful protection might allow others to utilize our technology without any compensation
to us and impair our ability to increase our licensing revenue.

The discovery of defects in our technology could expose us to liability for damages.

The discovery of a defect in our 1T−SRAM technology could lead our licensees to seek damages from us. Our standard license
terms include provisions waiving implied warranties regarding our technology and limiting our liability to our licensees. We cannot be
certain, however, that the waivers or limitations of liability contained in our license contracts will be enforceable.

Our failure to manage the expansion of our operations could reduce our potential revenue and threaten our future
profitability.

The size of our company has increased substantially as we grew from 43 employees in January 2001 to 80 employees in

December 2006. The efficient management of our planned expansion of the development, licensing and marketing of our technology,
including through the acquisition of other companies will require us to continue to—

•  implement and manage new marketing channels to penetrate different and broader markets for our 1T−SRAM technologies;
•  manage an increasing number of complex relationships with licensees and co−marketers and their customers and other third

parties;

•  expand our capabilities to deliver our technologies to our customers;
•  improve our operating systems, procedures and financial controls on a timely basis;
•  hire additional key management and technical personnel; and
•  expand, train and manage our workforce and, in particular, our development, sales, marketing and support organizations.
We cannot assure you that we will adequately manage our growth or meet the foregoing objectives. A failure to do so could

jeopardize our future revenues and cause our stock price to fall.

23

Source: MoSys, Inc., 10−K, March 13, 2007

If we fail to retain key personnel, our business and growth could be negatively affected.

Our business has been dependent to a significant degree upon the services of a small number of executive officers and technical
employees, including Dr. Wingyu Leung, our Executive Vice President and Chief Technical Officer. The loss of his services could
negatively impact our technology development efforts and our ability to perform our existing agreements and obtain new customers.
We generally have not entered into employment or non−competition agreements with any of our employees and do not maintain
key−man life insurance on the lives of any of our key personnel.

Our failure to successfully address the potential difficulties associated with our international operations could increase our
costs of operation and negatively impact our revenue.

We are subject to many difficulties posed by doing business internationally, including—
•  foreign currency exchange fluctuations;
•  unanticipated changes in local regulation;
•  potentially adverse tax consequences, such as withholding taxes;
•  political and economic instability; and
•  reduced or limited protection of our intellectual property.
Because we anticipate that licenses to companies that operate primarily outside the United States will account for a substantial
portion of our licensing revenue in future periods, the occurrence of any of these circumstances could significantly increase our costs
of operation, delay the timing of our revenue and harm our profitability.

Provisions of our certificate of incorporation and bylaws or Delaware law might delay or prevent a change of control
transaction and depress the market price of our stock.

Various provisions of our certificate of incorporation and bylaws might have the effect of making it more difficult for a third party

to acquire, or discouraging a third party from attempting to acquire, control of our company. These provisions could limit the price
that certain investors might be willing to pay in the future for shares of our common stock. Certain of these provisions eliminate
cumulative voting in the election of directors, limit the right of stockholders to call special meetings and establish specific procedures
for director nominations by stockholders and the submission of other proposals for consideration at stockholder meetings.

We are also subject to provisions of Delaware law which could delay or make more difficult a merger, tender offer or proxy

contest involving our company. In particular, Section 203 of the Delaware General Corporation Law prohibits a Delaware corporation
from engaging in any business combination with any interested stockholder for a period of three years unless specific conditions are
met. Any of these provisions could have the effect of delaying, deferring or preventing a change in control, including without
limitation, discouraging a proxy contest or making more difficult the acquisition of a substantial block of our common stock.

Our board of directors may issue up to 20,000,000 shares of preferred stock without stockholder approval on such terms as the
board might determine. The rights of the holders of common stock will be subject to, and might be adversely affected by, the rights of
the holders of any preferred stock that might be issued in the future.

Our stockholder rights plan could prevent stockholders from receiving a premium over the market price for their shares from
a potential acquirer.

We have adopted a stockholder rights plan, which entitles our stockholders to rights to acquire additional shares of our common

stock generally when a third party acquires 15% of our common stock or

24

Source: MoSys, Inc., 10−K, March 13, 2007

commences or announces its intent to commence a tender offer for at least 15% of our common stock. In 2004, we amended our
stockholder rights plan twice; once, in connection with the proposed acquisition of corporation by Synopsys, Inc, and a second time to
permit the acquisition of shares representing more than 15% of our common stock by a brokerage firm that manages independent
customer accounts and generally does not have any discretionary voting power with respect to such shares. Notwithstanding
amendments of this nature, our intention is to maintain and enforce the terms of this plan, which could delay, deter or prevent an
investor from acquiring us in a transaction that could otherwise result in stockholders receiving a premium over the market price for
their shares of common stock.

Potential volatility of the price of our common stock could negatively affect your investment.

We cannot assure you that there will continue to be an active trading market for our common stock. Recently, the stock market, as

well as our common stock, has experienced significant price and volume fluctuations. Market prices of securities of technology
companies have been highly volatile and frequently reach levels that bear no relationship to the operating performance of such
companies. These market prices generally are not sustainable and are subject to wide variations. If our common stock trades to
unsustainably high levels, it is likely that the market price of our common stock will thereafter experience a material decline. In the
past we have announced share repurchase programs approved by our board of directors and might adopt such repurchase programs
from time to time. Any such share repurchases could impact the price of our common stock and increase volatility.

In the past, securities class action litigation has often been brought against a company following periods of volatility in the market
price of its securities. We could be the target of similar litigation in the future. Securities litigation could cause us to incur substantial
costs, divert management’s attention and resources, harm our reputation in the industry and the securities markets and reduce our
profitability.

The price of our stock could decrease as a result of shares being sold in the market by directors, officers and other significant
stockholders.

Sales of a substantial number of shares of common stock in the public market could adversely affect the market price of the
common stock prevailing from time to time. From time to time members of our board of directors and management may implement
safe harbor stock trading plans under Rule 10b5−1 of the Securities Exchange Act of 1934. Pre−designated trading under such plans
may cause unexpected declines in the market price of our common stock. In addition, subject to compliance with applicable securities
laws and our insider trading policies, each of our directors and executive officers may sell shares of common stock from time to time.

 Properties

Our principal administrative, sales, marketing, support and research and development functions are located in a leased facility in
Sunnyvale, California. We currently occupy approximately 26,000 square feet of space in the Sunnyvale facility, the lease for which
extends through June 2010. We have leased approximately 19,000 square feet of space in Ontario, Canada for our research and
development facility. The lease expires at the end of April 2008. In connection with the closure of ATMOS’ operation, in July 2005,
we signed an agreement to sublease the ATMOS facility, which we occupy under long−term leases in Canada. The sublease expires at
the end of April 2008. We have leased approximately 3,700 square feet of space in Seoul, South Korea for our engineering design
center. This lease expires at the end of April 2008. In December 2006, we signed a new lease agreement for our sales office in Japan.
Under the new lease agreement, we occupy approximately 1,200 square feet of space in Tokyo, Japan. This lease expires in
December 2008. Effective September 30, 2006, we closed our office located in Sophia−Antipolis,

 Legal Proceedings

On March 31, 2004, UniRAM Technology, Inc. filed a complaint against us in the United States District Court for the Northern
District of California, alleging trade secret misappropriation and patent infringement. UniRAM’s complaint asserts that it provided
trade secret information to TSMC in 1996−97 and speculated that we improperly obtained unspecified trade secrets of UniRAM from
TSMC in an unknown manner. Subsequent to March 31, 2004, UniRAM amended its complaint twice to add TSMC as a defendant
and additional allegations to the suit, and to drop all infringement claims for one of the two patents identified in the initial complaint.
On October 24, 2006, we entered into a settlement agreement with UniRAM under which we and UniRAM agreed to dismiss all
outstanding claims and counterclaims with prejudice, and we paid UniRAM $2.4 million and received a complete release of all claims
as well as a future fully paid license for ourselves and all of our licensees with respect to UniRAM’s relevant intellectual property.

From time to time we may be subject to legal proceedings and claims in the ordinary course of business. These claims, even if not

meritorious, could result in the expenditure of significant financial resources and diversion of management efforts.

 Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with

the accompanying consolidated financial statements and notes included in this report.

Overview

We design, develop, market and license memory technologies used by the semiconductor industry and electronic product

manufacturers. We have developed a patented semiconductor memory technology, called 1T−SRAM that offers a combination of high
density, low power consumption and high speed at performance and cost levels that other available memory technologies do not
match. We license this technology to companies that incorporate, or embed, memory on complex integrated circuits, such as SoCs. We
have also sold memory chips based on our 1T−SRAM technologies, but in 2004, we ceased actively selling them. We do not expect to
make and sell memory chips in the future.

Using elements of our existing memory technology as a foundation, we completed development of our first memory chips

incorporating our 1T−SRAM technologies in the fourth quarter of 1998. We signed our first license agreement related to our
1T−SRAM technologies at the end of the fourth quarter of 1998 and recognized licensing revenue from our 1T−SRAM technologies
for the first time in the first quarter of 2000. Since then, we have introduced improved and enhanced versions of our technology, such
as 1T−SRAM−R, 1T−SRAM−M, and 1T−SRAM−Q.

We generate revenue from licensing our memory technologies, which revenue consists of licensing revenues, customization
services, maintenance and support fees and royalties. Royalty revenues are earned under each of our license agreements when our
licensees manufacture or sell products that incorporate any of our 1T−SRAM technologies and report the results to us. Generally, we
expect our total sales cycle, or the period from our initial discussion with a prospective licensee to our receipt of royalties from the
licensee’s use of our 1T−SRAM technologies, to run from 18 to 24 months after the commencement of the project. The portion of our
sales cycle from the initial discussion to the receipt of license fees may run from six to 12 months, depending on the complexity of the
proposed project and degree of customization required.

In 2005, we began delivering our new family of 1T−SRAM CLASSIC Memory Macro products to licensees. These macros are

silicon−proven, high−density solutions offering customers rapid memory block integration into their SoC designs. They are
pre−configured and require minimal additional customization, and we believe they will enable us to increase our penetration of the
market for very dense, low power, high speed embedded memory applications.

Sources of Revenue

We generate two types of revenue: licensing and royalties.

Licensing.   Our license agreements involve long sales cycles, which makes it difficult to predict when the agreements will be

signed. In addition, our licensing revenues fluctuate from period−to−period, and it is difficult for us to predict the timing and
magnitude of such revenue from quarter−to−quarter. Moreover, we believe that the amount of licensing revenues for any period is not
necessarily indicative of results in any future period. Our future revenue results are subject to a number of factors, particularly those
described in Part I, Item 1A. “Risk Factors.”

Our licensing revenue consists of fees for providing circuit design, layout and design verification and granting a license to a
customer for embedding our memory technology into its product. For some customers, we also provide engineering support services
to assist in the initial production of products utilizing the licensed 1T−SRAM technologies. License fees generally range from
$100,000 to several million dollars per contract, depending on the scope and complexity of the development project, and the extent of

30

Source: MoSys, Inc., 10−K, March 13, 2007

the licensee’s rights. The licensee generally pays the license fees in installments at the beginning of the license term and upon the
attainment of specified milestones. The vast majority of our contracts allow billing between milestones based on work performed.
Fees billed prior to revenue recognition are recorded as deferred revenue.

For license agreements that do not require significant development, modification or customization, revenues are recognized when
there is persuasive evidence of an arrangement, delivery has occurred, fees are fixed or determinable and collectibility is probable. If
any of these criteria is not met, we defer recognizing the revenue until such time as all criteria are met. For license agreements where 
a license is granted and  no other deliverables are required, revenues are recognized when persuasive evidence of an arrangement
exists, fees are fixed or determinable and collectibility is probable. However, if the agreement involves performance specifications that
we have significant experience in meeting and the cost of contract completion can be reasonably estimated, we recognize revenue over
the period in which the contract services are performed under the percentage of completion accounting method. We use actual direct
labor hours incurred to measure progress towards completion. We periodically evaluate the actual status of each project to determine
whether the estimates to complete each contract remain accurate and update our estimated costs to complete as necessary. Revenue
recognized in any period is dependent on our progress toward completion of projects in progress. Significant management judgment
and discretion are used to estimate total direct labor hours. Changes in or deviations from these estimates could have a material effect
on the amount of revenue we recognize in any period. If the amount of revenue recognized under the percentage of completion method
exceeds the amount of billings to a customer, then under the percentage of completion accounting method, we account for the excess
amount as an unbilled contract receivable. Our total unbilled contract receivable was $360,000 and $368,000 as of December 31, 2006
and 2005, respectively. For agreements involving performance specifications that we have not met and for which we lack the
historical experience to reasonably estimate the costs, we defer recognition of all revenue and related direct costs until all deliverables
are met and recognize revenue under the completed contract accounting method.

From time to time, a licensee may cancel a project during the development phase. Such a cancellation is not within our control and

is often caused by changes in market conditions or the licensee’s business. Cancellations of this nature are an aspect of our licensing
business, and most of our contracts allow us to retain all payments that we have received or are entitled to collect for items and
services provided before the cancellation occurs. We will consider a project to have been canceled even in the absence of specific
notice from our licensee, if there has been no activity under the contract for more than six months, and we believe that completion of
the contract is unlikely. In this event, we recognize revenue in the amount of cash received, if we have performed a sufficient portion
of the development services. If a cancelled contract had been entered into before the establishment of technological feasibility, the
costs associated with the contract would have been expensed prior to the recognition of revenue. In that case, there would be no costs
associated with that revenue recognition, and gross margin would increase for the corresponding period. In 2006, we recognized
$225,000 of licensing revenue from cancelled contracts, compared to $240,000 in 2005 and none in 2004.

Royalty.   Each of our license agreements provides for royalty payments at a stated rate. We negotiate royalty rates by taking into
account such factors as the anticipated volume of the licensee’s sales of products utilizing our technologies and the cost savings to be
achieved by the licensee through the use of our technology. Our license agreements generally require the licensee to report the
manufacture or sale of products that include our technology after the end of the quarter in which the sale or manufacture occurs.

As with our licensing revenues, the timing and level of royalties are difficult to predict. They depend on the licensee’s ability to
market, produce and sell products incorporating our technology. Many of the products of our licensees that are currently subject to
licenses from us are consumer products, such as

31

Source: MoSys, Inc., 10−K, March 13, 2007

electronic game consoles, for which demand can be seasonal and generally highest in the fourth quarter. For a discussion of factors
that could contribute to the fluctuation of our revenues, see Part I, Item 1A. “Risk Factors—Our lengthy licensing cycle and our
licensees’ lengthy product development cycle will make the operating results of our licensing business difficult to predict,” and
“—Anything that negatively affects the businesses of our licensees could negatively impact our revenue.”

Critical Accounting Policies and Estimates

Use of estimates.   Our discussion and analysis of our financial condition and results of operation are based upon our consolidated
financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The
preparation of these financial statements requires us to make certain estimates and judgments that affect the reported amounts of
assets, liabilities, revenues and expenses. On an ongoing basis we make these estimates based on our historical experience and on
assumptions that we consider reasonable under the circumstances. Actual results may differ from these estimates, and reported results
could differ under different assumptions or conditions

We apply estimates and judgments in the following manner:

Licensing Revenue Recognition.   For license agreements that do not require significant development, modification or

customization, revenues are recognized when there is persuasive evidence of an arrangement, delivery has occurred, fees are fixed or
determinable and collectibility is probable. If any of these criteria are not met, we defer recognizing the revenue until such time as all
criteria are met. For license agreements, which require no deliverables, revenues are recognized when persuasive evidence of an
arrangement exists, fees are fixed or determinable and collectibility is probable. As a consequence, the timing of this revenue
recognition depends upon our subjective evaluation of each of these elements.

For those contracts requiring us to develop a design that meets a licensee’s specifications, we apply SOP 81−1 “Accounting for
Performance of Construction−Type and Certain Production−Type Contracts”. In accordance with SOP 81−1 when license agreements
include deliverables that require “significant production, modification or customization”, contract accounting is applied. If a licensing
contract involves performance specifications that we have significant experience in meeting and the direct labor hours to be incurred
to complete the contract can be reasonably estimated, we recognize the revenue over the period in which the contract services are
performed using the percentage of completion method. The percentage of completion method includes judgmental elements, such as
determining that we have the experience to meet the design specifications and estimation of the total direct labor hours. We follow this
method because we can obtain reasonably dependable estimates of the direct labor hours to perform the contracted services. The direct
labor hours for the development of the licensee’s design are estimated at the beginning of the contract. As these direct labor hours are
incurred, they are used as a measure of progress towards completion. We have the ability to reasonably estimate direct labor hours on
a contract−by−contract basis from our experience in developing prior licensee’s designs. During the contract performance period, we
review estimates of direct labor hours to complete the contracts as the contract progresses to completion and will revise our estimates
of revenue and gross profit under the contract if we revise the estimations of the direct labor hours to complete. Our policy is to reflect
any revision in the contract gross profit estimate in reported income in the period in which the facts giving rise to the revision become
known. Under the percentage of completion method, provisions for estimated losses on uncompleted contracts are recognized in the
period in which the likelihood of such losses is determined.

For contracts involving design specifications that we have not met previously, we defer the recognition of revenue until the design
meets the contractual design specifications and expense the cost of services as incurred. When we have experience in meeting design
specifications but believe that we do not have significant experience to reasonably estimate the direct labor hours related to services to
meet a design specification, we defer both the recognition of revenue and the cost. For these arrangements, we recognize

32

revenue using the completed contract method. Under the completed contract method, we recognize revenue when we complete the
milestones. In 2006 and 2005, none of our license revenue was recognized under the completed contract method.

We also provide support and maintenance under many of our license agreements. Under these arrangements, we provide
unspecified upgrades, design rule changes and technical support. No other upgrades, products or other post−contract support are
provided. When we provide a combination of services related to licensing and support and maintenance to customers, in addition to
the considerations noted above, we evaluate the arrangements under EITF 00−21, “Revenue Arrangements with Multiple
Deliverables”. Specifically, we analyze the separate elements to determine if vendor specific objective evidence, or VSOE, exists for
the undelivered elements. We believe we have established VSOE for our support and maintenance arrangements. These arrangements
are renewable annually by the customer. Support and maintenance revenue is recognized at its fair value ratably over the period during
which the obligation exists, typically 12 months. Revenue from support and maintenance service represented $287,000 and $512,000
in 2006 and 2005, respectively, and was included in licensing revenue in the statement of operations.

Royalty Revenue Recognition.   Licensing contracts also provide for royalty payments at a stated rate based on actual units
produced and/or sold. Licensees generally report the manufacture or sale of products that include our 1T−SRAM technologies after
the end of the quarter in which the sale or manufacture occurs. As such, we generally recognize royalties in the quarter in which we
receive the licensee’s report. In addition, in the fourth quarter of 2006, we recognized royalty revenue related in the same quarter of
2006 due to a contract amendment with a customer, which enabled us to report royalty revenue one quarter earlier than the previous
contract. As a result of this contract amendment, additional royalty revenue representing 30% of total revenue was recognized in the
fourth quarter of 2006. In future quarters, we will continue to recognize royalty revenue related to this amendment in the same quarter
in which the units are sold. In the first quarter of 2006, we began recognizing two types of prepaid royalties: pre−production royalties,
which cover a fixed number of future unit shipments and are paid in a lump sum when we enter into the licensing contract, and
post−production royalties, which are paid in a lump sum after the licensee commences production of the royalty−bearing product and
applied against future unit shipments. In either case, payments from these prepaid royalties are non−refundable. Under current
contracts, pre−production prepaid royalties are inseparable from our licensing activities. Thus, we include pre−production prepaid
royalties in licensing revenue. Post−production prepaid royalties, which are recognized at the time of the billing provided that no
future performance obligations exist, are included in royalty revenue.

Deferred tax valuation allowance.   When we prepare our consolidated financial statements, we estimate our income tax liability

for each of the various jurisdictions where we conduct business. This requires us to estimate our actual current tax exposure and to
assess temporary differences that result from differing treatment of certain items for tax and accounting purposes. These differences
result in deferred tax assets and liabilities, which we show on our consolidated balance sheet under the category of other current
assets. The net deferred tax assets are reduced by a valuation allowance if, based upon weighted available evidence, it is more likely
than not that some or all of the deferred tax assets will not be realized. We must make significant judgments to determine our
provision for income taxes, our deferred tax assets and liabilities and any valuation allowance to be recorded against our net deferred
tax asset. As of December 31, 2006, we had a valuation allowance of approximately $12.5 million, of which approximately $5.1
million was attributable to Canadian loss and research and development pool carryforwards, and $6.3 million was attributable to U.S.
and state net operating loss and tax credit carryforwards.

Stock−based compensation.   We adopted Financial Accounting Standards Board (FASB) Standard No. 123 (revised 2004),
“Share−Based Payment” (SFAS 123(R)) effective January 1, 2006 and selected the modified prospective transition method, which
requires us to recognize the fair value of the stock−based compensation in the net income (loss) in the current and future periods and
not to restate the impact of

33

Source: MoSys, Inc., 10−K, March 13, 2007

the adoption on the prior period financial statements. Upon adoption, we began estimating the value of employee stock options on the
date of grant using the Black−Scholes model. Prior to the adoption of SFAS 123(R), the value of each employee stock option was
estimated on the date of grant using the Black−Scholes model for the purpose of the pro forma financial disclosure in accordance with
Statement of Financial Accounting Standard 123 (SFAS 123), “Accounting for Stock−Based Compensation”. The determination of
fair value of share−based payment awards on the date of grant using an option−pricing model is affected by our stock price as well as
assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to the
expected stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. The
expected term of options granted is derived from historical data on employee exercises and post−vesting employment termination
behavior. The expected volatility is based on the historical and implied volatility of our stock price. Based on unvested stock options
outstanding as of December 31, 2006, the total compensation costs expected to be recognized over a weighted average period of
approximately 2.72 years is approximately $8.1 million. See note 7—Stock−based Compensation in the notes to our consolidated
financial statements for more discussion.

Years Ended December 31, 2006, 2005 and 2004

Revenue.   In 2006, total revenue increased to $14.9 million representing a 21% increase from total revenue in 2005. Licensing

revenue increased to $9.1 million in 2006 from $7.7 million in 2005 due to

34

Source: MoSys, Inc., 10−K, March 13, 2007

revenue recognized from several significant licensing contracts for our 90nm and 65nm process technology in 2006. Royalty revenue
increased to $5.8 million in 2006 from $4.5 million in 2005 primarily due to a contract amendment with a customer, which allowed us
to report royalty revenue one quarter earlier than the previous contract. As a result of this contract amendment, additional royalty
revenue representing 10% of total revenue was recognized in 2006. In future quarters, we will continue to recognize royalty revenue
related to this amendment in the same quarter in which the units are sold. In 2006, the royalty earned from the production of
GAMECUBE chips decreased to 3% of total revenue, compared to 14% in 2005, as the GAMECUBE video game products
approached the end of their product life cycles.

In 2005, total revenue increased to $12.3 million representing a 14% increase from total revenue in 2004. Licensing revenue
increased to $7.7 million in 2005 from $4.5 million in 2004 mainly due to increased numbers of projects commenced under new
contracts signed in 2005 and revenue generated under a large contract signed in 2003 and completed in 2005. Royalty revenue
decreased to $4.5 million in 2005 from $5.3 million in 2004 as customer sales of chips incorporating our technology declined.
Royalties related to the production of Nintendo GAMECUBE chips in 2005 was $1.7 million, which was consistent with royalties in
2004.

In 2004, total revenue was $10.8 million primarily from licensing and royalty activities. Total revenue was reduced by $450,000

for a reimbursement given to a customer for excess verification costs incurred by the customer.

During the years ended December 31, 2006 and 2005, our product sales were minimal. During the year ended December 31, 2004,

product sales were $952,000. In the second quarter of 2004, we notified customers of our decision to discontinue sale of our memory
chip products. As of the end of the third quarter of 2004, we had no remaining product inventory of value.

Gross Profit.   Gross profit increased to $13.4 million in 2006 from $10.3 million in 2005 mainly due to an increase in our
licensing revenue. Our gross profit as a percentage of total revenue increased to 90% in 2006 from 84% in 2005 primarily due to a
higher licensing gross profit, which increased to 84% of total licensing revenue in 2006 from 74% of total licensing revenue in 2005.
This increase in licensing gross profit as a percentage of licensing revenue resulted from lower costs for fulfilling our obligations
under large high margin contracts and our CLASSIC Memory Macro projects. This cost reduction was partially offset by stock−based
compensation expense of $225,000 recorded under SFAS 123(R). There was no stock−based compensation expense related to SFAS
123(R) in 2005. In addition, pre−production prepaid royalties included in licensing revenue contributed to an increased gross profit as
a percentage of total revenue because such royalties have no associated cost.

Gross profit increased to $10.3 million in 2005 from $8.6 million in 2004 primarily due to an increase in our licensing revenue.
Our gross profit as a percentage of total revenue increased to 84% in 2005 from 79% in 2004 primarily due to a higher licensing gross
profit, which increased to 74% of total licensing revenue in 2005 from 65% of total licensing revenue in 2004. This increase occurred
because of a lower cost for fulfilling our obligations under new license agreements which required less customization.

Gross profit decreased to $8.6 million in 2004 primarily due to the significant decline in our licensing revenue. Our gross profit as
a percentage of total revenue decreased to 79% in 2004 due to the decline in licensing gross profit which fell to 65% of total revenue
in 2004. This decline occurred because we incurred higher cost under new license agreements than we had originally estimated or had
historically experienced. In addition, we recognized revenue under some lower margin license projects including a few contracts in
which our estimated cost exceeded the amount of revenue to be recognized.

Research and Development.   Our research and development expenses include development and design of variations of the

1T−SRAM technologies for use in different manufacturing processes used by licensees and the development and testing of prototypes
to prove the technological feasibility of embedding our memory designs in the licensees’ products. Research and development
expenses increased to $8.2 million in 2006 from $5.8 million in 2005. This increase was primarily attributable to a lower allocation of
expenses to cost of licensing revenue in 2006 because of the high margin contracts, which requires less customization and engineering
efforts. Research and development expenses also increased as a result of the stock−based compensation expense of $993,000 under
SFAS 123(R).

Research and development expenses decreased to $5.8 million in 2005 from $8.1 million in 2004 mainly due to the closure of our

ATMOS research and development facility in Ottawa, Canada in November of 2004. There were no research and development
expenses incurred at the ATMOS facility in 2005 as compared to $2.2 million incurred in 2004.

Research and development expenses decreased to $8.1 million in 2004 mainly because more engineering time was spent on
licensing development projects, and therefore, more engineering expenses were allocated to cost of licensing revenue in 2004.
Effective November 10, 2004, we closed the ATMOS research and development facility in Ottawa, Canada and terminated the
employment of approximately 20 employees working there.

Selling, General and Administrative.   Selling, general and administrative expenses increased to $11.4 million in 2006 from $9.9

million in 2005 mainly due to stock−based compensation expense of $1.5 million under SFAS 123(R). Expenses related to the
UniRAM litigation in 2006 totaled approximately $1.7 million.  Expenses related to testing and assessment of effectiveness of our
internal control over financial reporting required by Section 404 of Sarbanes−Oxley Act were approximately $411,000 in 2006.

Selling, general and administrative expenses decreased to $9.9 million in 2005 from $13.3 million in 2004 when we incurred $5.5
million of expenses related to the aborted acquisition by Synopsys, Inc. and legal expenses related to litigation with Synopsys over its
abandonment of the acquisition, as well as $800,000 of expenses related to the UniRAM litigation. We did not incur Synopsys−related
costs in 2005, but incurred approximately $1.6 million of legal expenses related to the clams brought by UniRAM. Expenses related to
testing and assessment of effectiveness of our internal control over financial reporting required by Section 404 of Sarbanes−Oxley Act
were approximately $466,000 in 2005.

In addition to the Synopsys and UniRAM−related expenses in 2004, expenses related to testing and assessment of effectiveness of

our internal control over financial reporting required by Section 404 of Sarbanes−Oxley Act were approximately $690,000.

Litigation Settlement.   On October 24, 2006, we entered into a settlement agreement with UniRAM under which we and UniRAM
agreed to dismiss all outstanding claims and counterclaims with prejudice, and we paid UniRAM $2.4 million and received a complete
release of all claims as well as a future fully paid license for ourselves and all of our licensees with respect to UniRAM’s relevant
intellectual property.

Interest and Other Income.   Interest and other income increased to $3.3 million in 2006 from $2.6 million in 2005 primarily due

to higher interest rates but offset by a charge of $511,000 recorded in 2006 related to Japan withholding taxes paid by Japanese
licensees on our behalf. We do not expect any additional withholding tax reimbursement in the future as the U.S. − Japan income tax
treaty that took effect July 1, 2004 generally eliminated withholding taxes on royalties. Interest and other income decreased to $2.6
million in 2005 from $11.6 million in 2004, which included a $10 million merger termination fee paid by Synopsys. Interest income
increased to $2.6 million in 2005 from $1.5 million in 2004 due to higher interest rates in 2005.

Stock−based Compensation.   As a result of the adoption of SFAS 123(R) effective January 1, 2006, $2.7 million was recognized
as stock−based compensation expense during the year ended December 31, 2006. Of this amount, $19,000 was related to the issuance
of options to purchase our stock to newly appointed members of our board of directors that had an exercise price less than the fair
market value of our stock on the date of the option grant, which is permitted under our option plan.

During the years ended December 31, 2005 and 2004, we recorded stock compensation expenses of $36,000 and $68,000,

respectively, of which $0 and, $50,000, respectively, was attributable to the excess of the fair market value of our common stock over
the price at which we granted stock options to employees, which was permitted under our option plan. In 2005 and 2004, we incurred
$36,000 and $5,000, respectively, of stock compensation expenses related to the issuance of options to purchase our stock to newly
appointed members of our board of directors that had an exercise price less than the fair market value of our stock on the date of the
option grant, which was permitted under our option plan. Stock compensation expenses in 2004 also included $13,000 for
amortization of deferred compensation cost attributable to the fair market value of shares of our common stock issued to certain
employees of ATMOS.

During the year ended December 31, 2004, we recorded deferred compensation cost of $74,000, which would be amortized in
future periods. No such costs were incurred in 2005. The 2004 deferred compensation costs represented the intrinsic value of options
granted to purchase shares of our stock to newly appointed members of our board of directors that had an exercise price less than the
fair market

37

Source: MoSys, Inc., 10−K, March 13, 2007

value of our common stock on the date of the option grant, which was permitted under our option plan. This deferred compensation
cost is being amortized over the vesting period of 36 months using the graded vesting method.

Prior to the adoption of SFAS 123(R), deferred compensation expense was amortized using the graded vesting method over the
vesting period of each respective option, generally four years. The accelerated amortization results in expensing approximately 52% of
the total award in the first year, 27% in the second year, 15% in the third year and 6% in the fourth year.

Provision for Income Taxes.   Provisions (benefit) for income taxes of approximately $109,000, ($11,000), and $26,000, were
recorded in 2006, 2005, and 2004, respectively. The effective income tax rate was 2.1% for 2006, (0.4%) for 2005, and 1.4% for 2004.
As of December 31, 2006, we had net operating loss carryforwards of approximately $13.9 million for federal tax purposes,
approximately $11.5 million for state tax purposes and Canadian loss and research and development pool carryforwards of
approximately $13.0 million that are available to reduce future income tax liabilities to the extent permitted under federal, Canadian
and applicable state income tax laws. The net operating loss carryforwards expire from 2008 to 2026. The change in our effective tax
rate in 2006 was mainly due to an increase in foreign taxes. In 2007, we anticipate that our effective income tax rate will be less than
the federal statutory tax rate but higher than the 2006 effective income tax rate.

Liquidity and Capital Resources

As of December 31, 2006, we had cash and cash equivalents of $11.1 million, short−term investments and auction rate securities
of $70.7 million and long−term investments of $2.5 million resulting in a total balance of cash, cash equivalents, and investments of
$84.3 million. As of the same date, we had total working capital of $84.7 million. As of December 31, 2005, we had cash and cash
equivalents of $9.2 million, short−term investments and auction rate securities of $59.5 million and long−term investments of
$17.3 million resulting in a total balance of cash, cash equivalents, and investments of $86.0 million. As of the same date, we had total
working capital of $68.2 million. Our primary capital requirements are to fund working capital needs. We believe that our current
focus on licensing and royalty revenues with reduced levels of memory chip sales has generally enabled us to steadily improve our
liquidity.

Net cash provided by (used in) operating activities was ($5.6) million, ($1.3) million, and $2.7 million for the years ended 2006,

2005 and 2004, respectively. In 2006, net cash used in the operating activities primarily consisted of the net loss $5.3 million, an
increase in accounts receivable by $1.9 million, reduced deferred revenue of $690,000 and decreased accrued expenses and other
liabilities of $756,000 offset by the non−cash impact of stock−based compensation of $2.7 million under SFAS 123(R), and a
non−cash charge of $474,000 for depreciation and amortization. In 2005, net cash used in operating activities consisted primarily of
net loss of $3.0 million offset by a non−cash charge of $614,000 for depreciation and amortization and higher deferred revenue of
$808,000. In addition, net cash used in operating activities in 2005 included tax benefits associated with the exercise of stock options
of $482,000, which was recorded under additional paid in capital. In 2004, net cash provided by operating activities consisted
primarily of net loss of $1.9 million offset by a non−cash charge of $1.5 million for depreciation and amortization, reduced unbilled
contract receivables of $1.0 million, and prepaid expenses and other assets of $858,000, which included a reduction in deferred tax
assets in 2004. In addition, net cash provided by operating activities in 2004 included restructuring related liabilities of $429,000

Net cash provided by (used in) investing activities was approximately $3.7 million, ($22.8) million, and $7.9 million for the years

ended 2006, 2005, and 2004, respectively. In 2006, in addition to the investing activity of marketable securities, we purchased
$208,000 of property and equipment, consisting principally of engineering design software. In 2005, aside from investing in
marketable securities, we added $1.1 million of property and equipment primarily due to leasehold improvements related to our new
office lease

38

Source: MoSys, Inc., 10−K, March 13, 2007

for our U.S. corporate headquarters beginning in June 2005, new testing equipment and engineering design software. We also
purchased $349,000 of property and equipment in 2004, consisting principally of engineering design software.

Net cash provided by (used in) financing activities was approximately $3.8 million, $1.5 million, and ($982,000) for the years
ended 2006, 2005, and 2004, respectively. We received proceeds in the amount of $3.8 million and $1.5 million in 2006 and 2005,
respectively, from the exercise of employee options to purchase common stock. In 2004, the major financing use of cash was $4.7
million for the repurchase of 1.2 million shares of common stock. We received proceeds in the amount of $3.7 million from the
exercise of employee options to purchase common stock during 2004.

Our future liquidity and capital requirements are expected to vary from quarter to quarter, depending on numerous factors,

including—

•  level and timing of licensing and royalty revenues;
•  cost, timing and success of technology development efforts, including meeting customer design specifications;
•  market acceptance of our existing and future technologies and products;
•  competing technological and market developments;
•  cost of maintaining and enforcing patent claims and intellectual property rights;
•  variations in manufacturing yields, materials costs and other manufacturing risks;
•  costs of acquiring other businesses and integrating the acquired operations; and
•  profitability of our business.
We expect that existing cash, and equivalents, short−term and long−term investments along with our existing capital and cash

generated from operations, if any, will be sufficient to meet our capital requirements for the foreseeable future. We expect that a
licensing business such as ours generally will require less cash to support operations.

However, we cannot be certain that we will not require additional financing at some point in time. Should our cash resources prove

inadequate, we may need to raise additional funding through public or private financing. There can be no assurance that such
additional funding will be available to us on favorable terms, if at all. The failure to raise capital when needed could have a material,
adverse effect on our business and financial condition.

Item 7A.

 Quantitative and Qualitative Disclosures About Market Risk

Our investment portfolio consists of money market funds, auction rate securities, corporate−backed debt obligations and
mortgage−backed government obligations. The portfolio dollar−weighted average maturity of these investments is within twelve
months. Our primary objective with investment portfolio is to invest available cash while preserving principal and meeting liquidity
needs. In accordance with our investment policy, we place investments with high credit quality issuers and limit the amount of credit
exposure to any one issuer. These securities, which approximate $73.2 million as of December 31, 2006 and have an average interest
rate of approximately 4.9%, are subject to interest rate risks. As of December 31, 2006, our portfolio had unrealized losses of
approximately $79,000 as a result of rising interest rates. We believe these losses are temporary and expect to hold these investments
to maturity. However, based on the investment portfolio contents and our ability to hold these investments until maturity, we believe
that if a significant change in interest rates were to occur, it would not have a material effect on our financial condition.

 Controls and Procedures

(a)

 Management’s annual report on internal control over financial reporting

MoSys, Inc.’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as
such term is defined in Rules 13a−15(f ) and 15d−15(f)) under the Securities Exchange Act of 1934. In designing and evaluating the
disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and
operated, can provide only reasonable assurance of achieving the desired control objectives and management necessarily is required to
apply its judgment in evaluating the cost−benefit relationship of possible controls. Under the supervision and with the participation of
our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness
of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the
Committee of Sponsoring

41

Organizations of the Treadway Commission. Based on the evaluation, our management concluded that our internal control over

(b)

 Evaluation of disclosure controls and procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial

Officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as
defined in Rules 13a−15(e) and 15d−15(e) under the Securities Exchange Act of 1934. Based on this evaluation, our management
concluded that as of December 31, 2006, our disclosure controls and procedures were effective such that the information relating to
us, including our consolidated subsidiaries, required to be disclosed in our reports filed with the Securities and Exchange Commission
(SEC) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and is accumulated
and communicated to our management including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow
timely decisions regarding required disclosure.

(c)

 Changes in internal control

There was no change in the internal control over financial reporting during the fourth fiscal quarter of 2006 that has materially

affected, or is reasonably likely to materially affect our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

We have audited the accompanying consolidated balance sheets of MoSys, Inc. as of December 31, 2006 and 2005 and the related

consolidated statements of operations, stockholders’ equity, and cash flows for the years then ended. These financial statements are
the responsibility of the MoSys’ management. We have also audited Schedule II—Valuation and Qualifying Accounts as of and for
the years ended December 31, 2006 and 2005. Our responsibility is to express an opinion on these financial statements based on our
audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).
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, assessing the accounting principles used and significant estimates made by management, as well as evaluating
the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position
of MoSys at December 31, 2006 and 2005, and the results of its operations and its cash flows for the years then ended, in conformity
with accounting principles generally accepted in the United States of America. Also, in our opinion, Schedule II—Valuation and
Qualifying Accounts presents fairly, in all material respects, the information set forth therein as of and for the years ended
December 31, 2006 and 2005.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the

effectiveness of MoSys’ internal control over financial reporting as of December 31, 2006, based on criteria established in Internal
Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our
report dated March 12, 2007 expressed an unqualified opinion thereon.

As discussed in Note 1 to the consolidated financial statements, effective January 1, 2006, the Company adopted the provisions of

Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004), “Share−Based Payment”, (SFAS 123(R)).

Report of Independent Registered Public Accounting Firm on Internal
Control over Financial Reporting

Board of Directors and Stockholders
MoSys, Inc.
Sunnyvale, California

We have audited management’s assessment, included in the accompanying Management Report on Internal Control over Financial

Reporting, that MoSys, Inc. maintained effective internal control over financial reporting as of December 31, 2006, based on criteria
established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (the COSO criteria)”. The Company’s management is responsible for maintaining effective internal control over financial
reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an
opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting
based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control
over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over
financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal
control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a
reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect
on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,

projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of
changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, management’s assessment that MoSys maintained effective internal control over financial reporting as of

December 31, 2006, is fairly stated, in all material respects, based on the COSO criteria. Also in our opinion, MoSys maintained, in all
material respects, effective internal control over financial reporting as of December 31, 2006, based on the COSO criteria.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the
consolidated balance sheets as of December 31, 2006 and 2005 and the related consolidated statements of operations, stockholders’
equity, and cash flows for the years then ended, and the 2006 and 2005 financial statement schedule listed in the accompanying index,
of MoSys and our report dated March 12, 2007, expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

We have audited the accompanying consolidated statements of operations, stockholders’ equity, and cash flows of MoSys, Inc. for

the year ended December 31, 2004. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2) for
the year ended December 31, 2004. These financial statements and schedule are the responsibility of the Company’s management. Our
responsibility is to express an opinion on these financial statements and schedule based on our audit.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audits 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 consolidated results of their

operations and their cash flows for the year ended December 31, 2004, in conformity with U.S. generally accepted accounting
principles. Also, in our opinion, the related financial statement schedule for the year ended December 31, 2004, when considered in
relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: The Company and Summary of Significant Accounting Policies

The Company

MoSys, Inc. (the “Company”) was incorporated in California on September 16, 1991 to design, develop and market high

performance semiconductor memory products and technologies used by the semiconductor industry and electronic product
manufacturers. On September 12, 2000, the stockholders approved the Company’s reincorporation in Delaware.

The Company has developed an innovative embedded−memory technology, called 1T−SRAM, which the Company licenses on a

non−exclusive and worldwide basis to semiconductor companies and electronic product manufacturers. From its inception in 1991
through 1998, the Company focused primarily on the sale of stand−alone memory products. In the fourth quarter of 1998, the
Company changed the emphasis of its business model to focus primarily on the licensing of its 1T−SRAM technologies and
completed this transition in 2002 when a majority of the Company’s revenues were derived from licensing and royalty of its
1T−SRAM technologies. In the second quarter of 2004, the Company notified its customers of its decision to discontinue sales of its
memory chip products and only license its technology.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its wholly−owned subsidiaries. All intercompany

transactions and balances have been eliminated in consolidation. The Company reports financial results on a calendar fiscal year.
Certain amounts reported in previous years have been reclassed to conform the 2006 presentation.

Use of Estimates

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

Foreign Currency Translation

The Company has foreign offices located in Korea and Japan, which are operated by subsidiaries of the Company. The functional

currency of the Company’s foreign entities is the U.S. dollar. Accordingly, the financial statements of these entities are remeasured
into U.S. dollars in accordance with Statement of Financial Accounting Standards No. 52, “Foreign Currency Translation.” Exchange
gains or losses from remeasurement of monetary assets and liabilities that are not denominated in U.S. dollar were not material for any
period presented and are included in the consolidated statements of operations.

Cash Equivalents, Short−term and Long−term Investments

The Company accounts for investments in accordance with Statement of Financial Accounting Standards No. 115 “Accounting for

Certain Investments in Debt and Equity Securities”. Management determines the appropriate classification of debt securities at the
time of purchase. All securities are classified as available−for−sale. The Company’s short−term and long−term investments are carried
at fair value, based on quoted market prices, with the unrealized holding gains and losses reported in

57

Source: MoSys, Inc., 10−K, March 13, 2007

stockholders’ equity. The Company evaluates declines in market value for potential impairment if the decline results in a value below
cost and is determined to be other than temporary. Realized gains and losses and declines in the value judged to be
other−than−temporary are included in interest income. The cost of securities sold is based on the specific identification method.

The Company invests its excess cash in money market accounts and debt instruments and considers all highly liquid debt

instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original maturities
greater than three months and remaining maturities less than one year are classified as short−term investments. Investments with
remaining maturities greater than one year are classified as long−term investments.

Allowance for Doubtful Accounts

The Company determines its allowance for doubtful accounts to ensure that its trade receivables balances are not overstated due to
uncollectibility. The Company performs ongoing customer credit evaluations within the context of the industry in which it operates. A
specific allowance of up to 100% of the invoice value will be provided for any problematic customer balances. Delinquent account
balances are written off after management has determined that the likelihood of collection is not possible. There was no balance of
allowance for doubtful accounts in 2006. As of December 31, 2005, the Company reported a balance of $105,000 in its allowance for
doubtful accounts.

Unbilled Contract Receivable

Under the percentage of completion method, if the amount of revenue recognized exceeds the amount of billings to a customer; the

excess amount is carried as an unbilled contract receivable. The Company has recorded $360,000 and $368,000 of unbilled contract
receivable as of December 31, 2006 and 2005, respectively.

Property and Equipment

Property and equipment are stated at cost. Depreciation is generally computed using the straight−line method over the estimated

useful lives of the assets, generally three years. In 2005, the Company wrote off approximately $9.4 million of fully depreciated
assets. Depreciation and amortization expense for the years ended December 31, 2006, 2005, and 2004 was $474,000, $614,000, and
$1.5 million, respectively.

Valuation of Long−lived Assets

Long−lived assets, such as property, plant and equipment, are evaluated for impairment whenever events or changes in
circumstances indicate the carrying value of an asset may not be recoverable. An impairment loss is recognized when estimated
undiscounted future cash flows expected to result from the use of the asset plus net proceeds expected from disposition of the asset (if
any) are less than the carrying value of the asset. When impairment is identified, the carrying amount of the asset is reduced to its
estimated fair value.

58

Source: MoSys, Inc., 10−K, March 13, 2007

Goodwill

The Company reviews goodwill, recorded from the acquisition of ATMOS Corp. on August 2002, for impairment annually and
whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable in accordance with the
Statement of Financial Accounting Standards (SFAS) No. 142, “Goodwill and Other Intangible Assets.”  The provisions of SFAS
No. 142 require that a two−step impairment test be performed on goodwill. In the first step, the Company compares the fair value of
each reporting unit to its carrying value. Subsequent to the acquisition of ATMOS, its business became an integrated part of the
Company’s operations. In 2004, the Company closed the operation of ATMOS at its Canadian research and development facility.
Using the guidance in SFAS No. 142, the Company determined that it has only one reporting unit at the entity level. For step one, the
Company determines the fair value of its reporting unit using the market approach. Under the market approach, the Company
estimates the fair value based on the market value of the reporting unit at the entity level. If the fair value of the reporting unit exceeds
the carrying value of net assets to the reporting unit, goodwill is not impaired and the Company is not required to perform further
testing. If the carrying value of the net assets to the reporting unit exceeds the fair value of the reporting unit, then the Company must
perform the second step in order to determine the implied fair value of the reporting unit’s goodwill and compare it to the carrying
value of the reporting unit’s goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, then the
Company must record an impairment loss equal to the difference. The Company performs its annual impairment test during the third
quarter of each year and at times impairment indicators are noted. The Company performed the annual impairment test during the
third quarter of 2006 and the test did not indicate impairment of goodwill as of September 30, 2006. As of December 31, 2006, the
Company found no indicators of potential impairment.

Revenue Recognition

Licensing

Licensing revenue consists of fees earned for technology license agreements, engineering development and engineering support
services. For the license agreements that do not require significant development, modification or customization, revenues are generally
recognized when there is persuasive evidence of an arrangement, fees are fixed or determinable, delivery has occurred and
collectibility is probable. If any of these criteria are not met, revenues are deferred until such time as all criteria have been met. For
those license agreements where  a license is granted and no other deliverables are required, revenues are recognized when there is
persuasive evidence of an arrangement, fees are fixed or determinable and collectibility is probable.

For those contracts requiring the Company to develop a design that meets a licensee’s specifications, the Company applies SOP
81−1 “Accounting for Performance of Construction−Type and Certain Production−Type Contracts”. In accordance with SOP 81−1,
when license agreements include deliverables that require “significant production, modification or customization”, contract accounting
is applied. When the Company has significant experience in meeting the design specification involved in the contract and the direct
labor hours related to services under the contract can be reasonably estimated, the Company recognizes revenue over the period in
which the contract services are performed. For these arrangements, the Company recognizes revenue using the percentage of
completion method. The direct labor hours for the development of the licensee’s design are estimated at the beginning of the contract.
As these direct labor hours are incurred, they are used as a measure of progress towards completion. The Company has the ability to
reasonably estimate the direct labor hours on a contract−by−contract basis based on its experience in developing prior licensees’
designs. The Company periodically evaluates the actual status of each project to ensure that the estimates to complete each contract
remain accurate and updates its estimated costs to complete as necessary. Under the percentage of completion method, provisions for
estimated losses on uncompleted contracts are recognized in the period in which the likelihood of such

59

Source: MoSys, Inc., 10−K, March 13, 2007

losses is determined. Revenue recognized in any period is dependent on the Company’s progress toward completion of projects in
progress. Significant management judgment and discretion are used to estimate total direct labor hours. Any changes in or deviation
from these estimates could have a material effect on the amount of revenue the Company recognizes in any period. If inherent risks
make estimates doubtful, the contract is accounted for under the completed contract method.

For contracts involving design specifications that the Company has not previously met, the Company defers the recognition of all
revenue until the design meets the contractual design specifications and expenses the cost of revenue as incurred. When the Company
has experience in meeting design specifications but does not have significant experience to reasonably estimate the cost of services to
meet a design specification, the Company defers both the recognition of revenue and the cost. For these arrangements, the Company
recognizes revenue using the completed contract method. In 2006 and 2005, none of the Company’s license revenue was recognized
under the completed contract method.

The Company also provides support and maintenance. Under these arrangements, the Company provides unspecified upgrades,

design rule changes and technical support. No other upgrades, products or other post−contract support are provided. When the
Company provides a combination of services related to licensing and support and maintenance to customers, in addition to the
considerations noted above, the Company evaluates the arrangements under EITF 00−21, “Revenue Arrangements with Multiple
Deliverables” to determine if objective and reliable evidence exists for the undelivered elements. Currently, the Company believes it
has established vendor specific objective evidence, or VSOE, for its support and maintenance arrangements. These arrangements are
renewable annually by the customer. Support and maintenance revenue is recognized at its fair value ratably over the period during
which the obligation exists, typically 12 months.

From time to time, a licensee may cancel a project during the development phase. Such a cancellation is not within the Company’s
control and is often caused by changes in market conditions or the licensee’s business. Cancellations of this nature are an aspect of the
Company’s licensing business, and, in general license contracts signed since the beginning of 2002 allow the Company to retain all
payments that the Company has received or is entitled to collect for items and services provided before the cancellation occurs.
Typically under the Company’s license agreements, the licensee is obligated to complete the project within a stated timeframe,
including assisting the Company in completing the final milestone, and if the Company performs the contracted services, is obligated
to pay the license fees even if the licensee fails to complete verification or cancels the project prior to completion. For accounting
purposes the Company will consider a project to have been canceled even in the absence of specific notice from its licensee, if there
has been no activity under the contract for six months or longer, and the Company believes that completion of the contract is unlikely.
In this event, the Company recognizes revenue in the amount of cash received, if the Company has performed a sufficient portion of
the development services. If a cancelled contract had been entered into before the establishment of technological feasibility, the costs
associated with the contract would have been expensed prior to the recognition of revenue. In that case, there would be no costs
associated with that revenue recognition, and gross margin would increase for the corresponding period. The Company recognized
$225,000 and $240,000 of licensing revenue from cancelled contracts in 2006 and 2005, respectively.

Royalty

Licensing contracts also provide for royalty payments at a stated rate based on actual units produced and require licensees to report

the manufacture or sale of products that include the Company’s 1T−SRAM technologies after the end of the quarter in which the sale
or manufacture occurs. The Company generally recognizes royalties in the quarter in which the Company receives the licensee’s
report. In addition, in the fourth quarter of 2006, the Company recognized royalty revenue in the same quarter of 2006 due to a
contract amendment with a customer, which enabled the Company to report royalty revenue one quarter

60

Source: MoSys, Inc., 10−K, March 13, 2007

earlier than the previous contract. As a result of this contract amendment, additional royalty revenue representing 30% of total revenue
was recognized in the fourth quarter of 2006. In future quarters, the Company will continue to recognize royalty revenue related this
amendment in the same quarter in which the units are sold. Beginning with the first quarter of 2006, the Company is recognizing two
types of prepaid royalties: pre−production royalties, which cover a fixed number of future unit shipments and are paid in a lump sum
when the Company enters into the licensing contract, and post−production royalties, which are paid in a lump sum after the licensee
commences production of the royalty−bearing product and applied against future unit shipments. In either case, payments from these
prepaid royalties are non−refundable. Under current contracts, pre−production prepaid royalties are inseparable from the Company’s
licensing activities. Thus, the Company includes pre−production prepaid royalties in licensing revenue as contract services are
performed. Post−production prepaid royalties, which are recognized at the time of the billing provided that no future performance
obligations exist, are included in royalty revenue.

Product

Revenue from product sales is recognized upon shipment provided that persuasive evidence of a sales arrangement exists, the price

is fixed or determinable, title has transferred, collection of resulting receivables is reasonably assured, there are no customer
acceptance requirements and there are no remaining significant obligations. For each of the periods presented, there were no formal
acceptance provisions with the Company’s end customers. During 2004, we phased out sales of our proprietary 1T−SRAM memory
chips. The Company does not expect to sell memory chips in the future.

Cost of Revenue

Licensing

Cost of licensing revenue consists primarily of engineering costs directly related to engineering development projects specified in

agreements the Company has with licensees of its 1T−SRAM technologies. These projects typically include customization of
1T−SRAM circuitry to enable embedding its memory on a licensee’s integrated circuit and may include engineering support to assist
in the commencement of production of a licensee’s products. The Company recognizes costs of licensing revenue in the following
manner:

•  If licensing revenue is recognized using the percentage of completion method, the associated cost of licensing revenue is

recognized in the period in which the Company incurs the engineering costs.

•  If licensing revenue is recognized using the completed contract method, and to the extent that the amount of engineering cost

does not exceed the amount of the related licensing revenue, this cost is deferred on a contract−by−contract basis from the time
the Company has established technological feasibility of the product to be developed under the license. Technological feasibility
is established when the Company has completed all activities necessary to demonstrate that the licensee’s product can be
produced to meet the performance specifications when incorporating its technology. Deferred costs are charged to cost of
licensing revenue when the related revenue is recognized.

•  For contracts entered into prior to establishing technological feasibility, the Company does not defer related development costs,

but rather expense them in the period in which they are incurred. Consequently, upon completion of these contracts, the
Company recognizes the related revenues without any corresponding costs.

In addition, cost of licensing revenue includes costs related to support and maintenance services.

Royalty

There are no reported costs associated with royalty revenue.

Product

Cost of product revenue consists primarily of costs associated with the manufacture, assembly and testing of the Company’s
memory chip products by independent, third−party contractors. There were no reported costs associated with product revenue in 2005
as the products were sold from the inventory previously written off.

Research and Development

Engineering cost is generally recorded as research and development expense in the period incurred.

Stock−based Compensation

Prior to January 1, 2006, the Company accounted for stock−based compensation arrangements in accordance with the provisions
of APB No. 25 (APB 25), “Accounting for Stock Issued to Employees” and complied with the disclosure provisions of Statement of
Financial Accounting Standard No. 123 (SFAS 123), “Accounting for Stock−Based Compensation.”

Effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004),
“Share−Based Payment”, (SFAS 123(R)), which establishes accounting for recognizing the fair value of the stock−based payment
awards. Accordingly, the expense of these awards is recognized over the requisite service period, usually the vesting period, based on
the grant−date fair value.

The Company elected to adopt the modified prospective transition method as provided by SFAS 123(R). This method requires the

Company to apply the provision of SFAS 123(R) to all stock−based payment awards after the adoption date. In accordance with the
method, the Company’s consolidated financial statements for prior period have not been restated to reflect, and do not include, the
impact of SFAS 123(R).

The adoption of SFAS 123(R) had and will have a material impact on the Company’s consolidated financial position and results of

operations. See Note 7 for further information regarding the stock−based compensation assumptions and expenses, including pro
forma disclosures for prior periods as if the Company had recorded stock−based compensation expense.

Per Share Amounts

Basic net income (loss) per share is computed by dividing net income (loss) for the period by the weighted−average number of

shares of common stock outstanding during the period. Potential common shares are composed of incremental shares of common
stock issuable upon the exercise of stock options or warrants. Diluted net loss per share for the years ended December 31, 2006, 2005
and 2004 are the same as basic net loss per share for the same period because the impact of including potential common shares is
anti−dilutive. For the years ended December 31, 2006, 2005 and 2004, stock options to purchase 727,000, 1.4 million and 1.3 million
shares with exercise prices greater than the average market prices of common stock were excluded from computation of diluted net
loss per share as their inclusion would be anti−dilutive. The following table sets forth the computation of basic and diluted net income
per share for the periods indicated (in thousands, except per share amounts):

The Company accounts for income taxes using the asset and liability method as prescribed by Statement of Financial Accounting

Standards No. 109, “Accounting for Income Taxes” (SFAS 109). Under the asset and liability method, the expected future tax
consequences of temporary differences between the book and tax basis of assets and liabilities are recognized as deferred tax assets
and liabilities. A valuation allowance is established for any deferred tax assets for which realization is more likely than not that all or a
portion of the deferred tax assets will not be realized.

In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation (FIN) No. 48, “Accounting for Uncertainty

in Income Taxes−an interpretation of FASB Statement No. 109.” This Interpretation prescribes a recognition threshold and
measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax
return, and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and
transition. This Interpretation is effective for fiscal years beginning after December 15, 2006. Upon adoption, the cumulative effect of
applying the recognition and measurement provisions of FIN 48, if any, shall be reflected as an adjustment to the opening balance of
retained earnings. The Company does not expect that the adoption of FIN 48 will have a material impact on its consolidated financial
position, results of operations or cash flows.

Comprehensive Loss

Statement of Financial Accounting Standards No. 130,  “Reporting Comprehensive Income” (SFAS No. 130) requires the

Company to display comprehensive income and its components as part of the financial statements. The Company’s only component of
comprehensive loss is unrealized gains and losses on available for sale securities. Accumulated other comprehensive loss as of
December 31, 2006, 2005, and 2004 was ($79,000), ($389,000) and ($252,000), respectively. The changes in other comprehensive
loss were as follows, for the years ended December 31, 2006, 2005, and 2004:

Segment Reporting

Financial Accounting Standards Board Statement No. 131, “Disclosure about Segments of an Enterprise and Related Information”

(SFAS 131) requires that companies report separately in the financial statements certain financial and descriptive information about
operating segment profit or loss, certain specific revenue and expense items and segment assets. The Company operates in one
segment, using one measurement of profitability for its business. The Company has sales outside the United States that are described
in Note 9. The vast majority of long−lived assets are maintained in the United States.

Recent Accounting Pronouncements

In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48)—an interpretation

of FASB Statement No. 109. This Interpretation prescribes a recognition threshold and measurement attribute for the financial
statement recognition and measurement of a tax position taken or expected to be taken in a tax return, and provides guidance on
derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for
fiscal years beginning after December 15, 2006 and, as such, the Company must adopt FIN 48 at January 1, 2007.

In September 2006, the FASB issued Statement of Financial Accounting Standards (SFAS) No. 157, “Fair Value Measurement”,
(SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value in GAAP, and expands disclosures about
fair value measurements. This Statement is effective for financial statements issued for fiscal years beginning after November 15,
2007, and interim periods within those fiscal years. The Company is currently evaluating the impact SFAS 157 will have on its
consolidated financial statements.

In September 2006, the SEC issued Staff Accounting Bulletin (SAB) No. 108, “Considering the Effects of Prior Year

Misstatements when Quantifying Misstatements in Current Year Financial Statements” (SAB 108). SAB 108 expresses the SEC
Staff’s views regarding the process of quantifying financial statement misstatements. SAB 108 addresses the diversity in quantifying
financial statement misstatements and the potential under current practice used by the Company for the build up of improper amounts
on the balance sheet. The guidance is applicable to the Company for fiscal years ending after December 31, 2006.

Note 2: Restructuring

On November 10, 2004, the Company announced its plan to close the ATMOS research and development facility in Canada to

reduce operating expenses and to further align the Company’s business

64

Source: MoSys, Inc., 10−K, March 13, 2007

with market conditions, future revenue expectations and planned future product direction. As part of this plan, the Company
implemented a reduction in workforce of approximately 20 employees, which represented 20% of its workforce. On July 15, 2005, the
Company signed an agreement to sublease the ATMOS facility, which the Company occupies under long−term operating leases
through 2008.

The Company had a total restructuring estimated lease abandonment accrual of $208,000 and $293,000 at December 31, 2006 and

2005, respectively. The Company reviews these estimates periodically, and if the pertinent assumptions materially change, the
ultimate restructuring expense for the abandoned facilities will be adjusted in accordance with SFAS No. 146, “Accounting for Costs
Associated with Exit or Disposal Activities”. The following table summarizes 2006 activities under the Restructuring Plan (amounts in

In 2006, deferred costs of revenue included the stock−based compensation expense of $33,000. In 2006, the Company recorded

charges of $511,000 related to the reimbursement of Japan withholding taxes paid by Japanese licensees on the behalf of the
Company. The Company does not expect any additional withholding tax reimbursement in the future as the U.S. − Japan income tax
treaty that took effect July 1, 2004 generally eliminated withholding taxes on royalties. In 2004, the Company received a $10 million
termination fee from Synopsys as a result of the settlement agreement regarding the aborted merger.

U.S. Government Debt Securities.   The Company’s investment in U.S. government debt securities consists of low risk

government agency bonds typically with a rating of AAA. The unrealized losses on the Company’s investments in U.S. government
debt securities were caused by interest rate increases during 2006. Because the Company has the ability and intent to hold these
investments until a recovery of fair value, which may be maturity, the Company does not consider these investments to be
other−than−temporarily impaired at December 31, 2006.

Corporate Notes.   The Company’s investment in corporate notes consists primarily of investment grade corporate bonds and
notes. The unrealized losses on the Company’s investment grade corporate bonds and notes were caused by interest rate increases
during 2006. Due to the fact that the decline in market value is attributable to changes in interest rates and not credit quality, and
because the severity and duration of the unrealized losses were not significant, the Company considered these unrealized losses to be
temporary at December 31, 2006. Because the Company has the ability and intent to hold these investments until a recovery of fair
value, which may be maturity, the Company does not consider these investments to be other−than−temporarily impaired at
December 31, 2006.

The valuation allowance increased by $1.5 million, and $130,000 during the years ended December 31, 2006 and 2005,

respectively. The valuation allowance at December 31, 2006 includes $1.9 million related to stock option deductions incurred prior to
January 1, 2006, the benefit of which will be credited to additional paid in capital when realized.

As of December 31, 2006, the Company had net operating loss carryforwards of approximately $13.9 million for federal income
tax purposes and approximately $11.5 million for state income tax purposes. These losses are available to reduce taxable income and
expire beginning 2013 through 2026. Approximately $2.3 million of federal net operating loss carryforwards and $1.8 million of state
net operating loss carryforwards from 2006 are related to excess tax benefits from stock−based compensation and will be charged to
additional paid in capital when utilized.

The Company also had federal research and development tax credit carryforwards of approximately $957,000, which will expire

beginning in 2021, and California research and development credits of

68

Source: MoSys, Inc., 10−K, March 13, 2007

approximately $1.2 million, which do not have an expiration date. The Company had foreign tax credits available for federal income
tax purposes of approximately $1.2 million, which will begin to expire in 2008. The Company had Canadian operating loss and
research and development pool carryforwards of $13.0 million, which will begin to expire in 2008.

Utilization of the Company’s net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due

to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such an annual limitation
could result in the expiration or elimination of the net operating loss and tax credit carryforwards before utilization. Management does
not believe it is likely that utilization will in fact be significantly limited due to ownership change limitation provisions.

The Company’s U.S. income tax return for 2002 has been examined and is under appeal. Management believes that adequate

amounts have been provided for any adjustments that may ultimately result from this examination.

In the ordinary course of business, the Company enters into contractual arrangements under which the Company may agree to
indemnify the third party to such arrangement from any losses incurred relating to the services they perform on behalf of the Company
or for losses arising from certain events as defined within the particular contract, which may include, for example, litigation or claims
relating to patent infringement. The maximum amount of indemnification the Company could be required to make under these
agreements is generally limited to the fees received by the Company, although in some contracts the Company’s potential obligation
could be equal to the third parties’ actual damages and losses. The Company has not estimated the maximum potential amount of
indemnification liability under these agreements due to the limited history of prior claims and the unique facts and circumstances
applicable to

each particular agreement. To date, the Company has not made any payments related to these indemnifications.

Note 7: Stock−based Compensation

Equity Compensation Plans

Common Stock Option Plans

In 1996, the Company adopted the 1996 Stock Plan (the “1996 Plan”), which authorizes the board of directors to grant incentive
stock options and nonqualified stock options for up to 2,500,000 shares of common stock to employees, directors and consultants. The
option terms under the 1996 Plan are substantially the same as the 1992 Plan except that options granted under the 1996 Plan may be
exercised immediately. Common stock is purchased pursuant to the exercise of a maximum period of ten years after the date of grant.

The Company’s 2000 employee stock option plan (the “2000 Plan”) was adopted in October 2000 in connection with the
Company’s reincorporation in Delaware. In 2004, the Company obtained stockholder approval of its Amended and Restated 2000
Stock Option and Equity Incentive Plan (the “Amended 2000 Plan”) to provide additional incentive to its employees and directors.
The Amended 2000 Plan authorizes the board of directors or the compensation committee of the board of directors to grant a broad
range of awards in addition to stock options, including stock grants, restricted stock, performance−based awards, restricted stock units
representing a right to acquire shares in the future and stock appreciation rights and to determine the applicable terms, including price,
of such awards. Under the Amended 2000 Plan, the maximum number of shares reserved for issuance is 7,207,000, plus an annual
increase of 500,000 on January 1 of each year, or a lesser amount determined by our board of directors. The term of options granted
under the Amended 2000 Plan may not exceed ten years. The term of all incentive stock options granted to an optionee who, at the
time of grant, owns stock representing more than 10% of the voting power of all classes of the Company’s stock may not exceed five
years. Generally, 25% of the options granted under the Amended 2000 Plan will vest and become exercisable on the first anniversary
of the date of grant, and 1/48th of the options will vest and become exercisable each month thereafter.

The exercise price of incentive stock options granted under the Amended 2000 Plan must be at least equal to the fair market value

of the shares on the date of grant. The exercise price of nonstatutory stock options granted under the Amended 2000 Plan will be
determined by the board of directors or the compensation committee and the exercise price of a nonstatutory stock option is not
subject to any price restriction under the Amended 2000 Plan. No incentive stock option may be granted to any employee who on the
date of grant owns more than 10% of the Company’s common stock, unless the exercise price of the option is equal to at least 110% of
the fair market value of such shares on the date of grant. In addition, the Amended 2000 Plan provides for automatic acceleration of
vesting for options granted to non−employee directors in the event of an acquisition of the Company. Generally, options granted under
the Amended 2000 Plan after March 30, 2006 vest over a four−year period and are exercisable for a maximum period of six years after
the date of grant.

The Company may also award shares to new employees as a material inducement to the acceptance of employment with the

Company, which awards are not made under the Amended 2000 Plan. These grants must be approved by the compensation committee
of the board of directors, a majority of the independent directors or authorized executive officer, as determined under NASDAQ
Marketplace Rules.

Employee Stock Purchase Plan

The Company’s 2000 employee stock purchase plan was adopted in October 2000 in connection with the Company’s Delaware

re−incorporation, to become effective upon the pricing date of the Company’s

70

initial public offering. A total of 500,000 shares of common stock have been reserved for issuance under the purchase plan. In
addition, the purchase plan provides for an automatic annual increase in the number of shares reserved under the plan on January 1 of
each year, equal to the lesser of 100,000 shares, one percent of the Company’s outstanding shares of common stock on such date or a
lesser amount determined by the board of directors. The purchase plan, which is intended to qualify under Section 423 of the Internal
Revenue Code, is administered by the board of directors or a committee appointed by the board of directors.

Employees, including officers and employee directors but excluding 5% stockholders, are eligible to participate if they are
customarily employed for at least 20 hours per week and for more than five months in any calendar year. The purchase plan permits
eligible employees to purchase common stock through payroll deductions, which may not exceed 10% of an employee’s
compensation. Employees will be permitted to invest a maximum of $25,000 in any offering period.

The purchase plan has been implemented in a series of overlapping offering periods, each to be approximately 12 months in

duration. Offering periods begin on the first trading day on or after January 1 and July 1 of each year and end on the last trading day in
the period ending twelve months later. Each participant is granted an option on the first day of the offering period, and such option
will be automatically exercised at the end of month six of the offering period and on the last day of the offering period. The purchase
price of the common stock under the purchase plan is equal to 85% of the lesser of the fair market value per share of common stock on
the start date of the offering period or on the date on which the option is exercised. Employees may end their participation in an
offering period at any time during that period, and participation ends automatically on termination of employment with the Company.
The purchase plan will terminate in June 2010, unless sooner terminated by the board of directors.

Pursuant to authorization by the compensation committee of the board of directors, the Company’s 2000 Employee Stock Purchase

Plan (the “ESPP”) is currently inactive.

Stock−based Compensation Expense

Effective January 1, 2006, the Company adopted SFAS 123(R). See Note 1 for a description of the adoption of SFAS123(R). As a

result of the adoption of SFAS 123(R), $2.7 million was recognized as stock−based compensation expense in 2006. The total
compensation cost of options granted, but not yet vested, as of December 31, 2006 was $8.1 million, which is expected to be
recognized as expense over a weighted average period of approximately 2.72 years. Basic and diluted loss per share for the year ended
December 31, 2006 was $(0.17). The net effect on loss per share (basic and diluted) of the adoption of SFAS 123(R) for the year
ended December 31, 2006 was $0.09.

SFAS 123(R) requires the Company to present the tax benefits resulting from tax deductions in excess of the compensation cost
recognized from the exercise of stock options as financing cash flows in the Statement of Cash Flows. Such tax benefit would have
been presented as operating cash flows under SFAS 123. For the year ended December 31, 2006, there were no such tax benefits
associated with the exercise of stock options due to the Company’s loss position.

In November 2005, the FASB issued FASB Staff Position (FSP) No. FAS 123(R) −3, “Transition Election Related to Accounting

for Tax Effects of Share−Based Payment Awards” (FSP 123R−3). The Company has elected to adopt the alternative transition
(short−cut) method described in the FSP 123R−3 for calculating the tax effects of stock−based compensation pursuant to SFAS 123R.
The alternative transition method includes simplified methods to establish the beginning balance of the additional paid−in capital pool
(APIC pool) related to the tax effects of employee stock−based compensation and to determine the subsequent impact on the APIC
pool and Consolidated Statements of Cash Flows of the tax effects of employee stock−based compensation awards that are
outstanding upon adoption of SFAS 123R.

Valuation Assumptions and Expense Information under SFAS 123(R)

As prescribed in SFAS 123(R), the fair value of the Company’s share−based payment awards for the year ended December 31,

2006 is estimated on the grant date using a Black−Scholes valuation method and an option−pricing model with the following
assumptions:

Employee stock options
Expected life (in years)
Risk−free interest rate
Volatility
Dividend yield

Year Ended December 31,
2006

4.0

4.4% − 5.1%
47.1% − 56.0%
0%

The risk−free interest rate is derived from the Daily Treasury Yield Curve Rates as published by Department of the Treasury as of

the grant date for terms equal to the expected terms of the options. The expected volatility is based on the combination of historical
volatility, excluding the volatility during the period of one time non−recurring event, which was the aborted Synopsis acquisition for
the Company in 2004, and the expected future volatility of the Company’s stock price. The expected term of options granted is
derived from historical data based on employee exercises and post−vesting employment termination behavior. The dividend yield of
zero is applied since the Company never paid dividends and has no intention to pay dividends in the near future.

The stock−based compensation expense of $2.7 million included compensation expense for share−based awards granted prior to,

but not yet vested as of January 1, 2006 based on the grant date fair value estimated in accordance with the pro forma provisions of
SFAS 123 and compensation expense for the share−based awards granted subsequent to January 1, 2006, based on the grant date fair
value estimated in accordance with the provisions of SFAS 123(R). As required by SFAS 123(R), the stock−based compensation
expense is calculated with the estimated forfeiture rate. An annualized forfeiture rate of 15% is used as a best estimate of future
forfeitures based on the Company’s historical forfeiture experience. Under the true−up provisions of SFAS 123(R), the stock−based
compensation expense will be adjusted in later periods if the actual forfeiture rate differs from the estimate.

Pro Forma Information Prior to the Adoption of SFAS 123(R)

Prior to January 1, 2006, the Company accounted for stock−based compensation arrangements in accordance with the provisions
of APB No. 25 (APB 25), “Accounting for Stock Issued to Employees” and complies with the disclosure provisions of Statement of
Financial Accounting Standard No. 123 (“SFAS 123”), “Accounting for Stock−Based Compensation.” Under APB No. 25,
compensation cost is, in general, recognized based on the excess, if any, of the fair market value of the Company’s stock on the date of
grant over the amount an employee must pay to acquire the stock. Equity instruments issued to non−employees are accounted for in
accordance with the provisions of SFAS No. 123 and Emerging Issues Task Force 96−18. Deferred stock−based compensation is
being amortized using the graded vesting method over the vesting period of each respective option, which is generally four years.

Had compensation cost for the Company’s option plans been determined based on the fair value at the grant dates, as prescribed in

SFAS 123, the Company’s net income (loss) would have been as follows (in thousands, except per share amounts):

Net loss:

Note 8. Stockholders’ Equity

The Company’s board of directors may issue up to 20,000,000 shares of preferred stock without stockholder approval on such
terms as the board might determine. The rights of the holders of common stock will be subject to, and might be adversely affected by,
the rights of the holders of any preferred stock that might be issued in the future.

Stockholder Rights Plan

The Company’s Stockholder Rights Plan, which was adopted in October 2000 and became effective June 27, 2001, is intended to

protect stockholders from unfair or unfriendly takeover practices. In accordance with this plan, the board of directors declared a
dividend distribution of one Series AA preferred stock purchase right on each outstanding share of its common stock held as of
June 27, 2001, and on each share of common stock issued by the Company thereafter. Each right entitles the registered holder to
purchase from the Company one one−thousandth share of Series AA preferred stock at a price of $110. The rights become exercisable
in certain circumstances, including the acquisition by any person or group, or the commencement or announcement of a tender or
exchange offer for the acquisition, of beneficial ownership of 15 % or more of the Company’s common stock without the approval of
the board of directors (except for certain affiliates prior to the effective date of the Plan as to whom this ownership limit is 25%). The
rights do not confer any rights as a stockholder until they are exercised. In the event the rights become exercisable, each right will
entitle the holder to acquire shares of common stock of the Company or the acquiring corporation (in the event of merger or similar
business combination) having a value equal to twice the purchase price of the right. The rights are redeemable by the Company prior
to exercise at $0.01 per right and expire on October 11, 2010.

In 2004, the Company amended its Stockholder Rights Plan twice; once, in connection with the proposed acquisition of the

Company by Synopsys, Inc, and a second time to permit the acquisition of shares representing more than 15% of its common stock by
a brokerage firm that manages independent customer accounts and generally does not have any discretionary voting power with
respect to such shares. Notwithstanding amendments of this nature, the Company’s intention is to maintain and enforce the terms of
this plan, which could delay, deter or prevent an investor from acquiring the Company in a transaction that could otherwise result in
stockholders receiving a premium over the market price for their shares of common stock.

Note 9: Retirement Savings Plan

Effective January 1997, the Company adopted the MoSys 401(k) Plan (the “Savings Plan”) which qualifies as a thrift plan under
Section 401(k) of the Internal Revenue Code. All full−time employees who are at least 21 years old are eligible to participate in the
Savings Plan at the time of hire. Participants may contribute up to 15% of their earnings to the Savings Plan. The Company makes a
Matching Contribution on behalf of each Participant in an amount equal to 25% of a Participant’s Deferral Contributions during the
Plan Year. The Company made matching contributions of $153,000, $127,000, and $110,000, in 2006, 2005, and 2004, respectively.

Note 10: Business Segments, Concentration of Credit Risk and Significant Customers

The Company has adopted SFAS No. 131, “Disclosure about Segments of an Enterprise and Related Information.” Although the
Company offers various intellectual property components and services to its customers, the Company does not manage its operations
by these intellectual property components and services, but instead views the Company as one operating segment when making
business decisions. The Company does not manage its operations on a geographical basis. Revenue attributed to the United States and
to all foreign countries is based on the geographical location of the customer. The Company uses one measurement of profitability for
its business.

The Company supplies semiconductor memories to the electronics industry. This industry segment is characterized by rapid

technological change and significant competition.

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash,
cash equivalents, short−term and long−term investments and accounts receivable. Cash, cash equivalents, short−term and long term
investments are deposited with high credit quality institutions.

The Company sold its products and licensed its 1T−SRAM technologies to customers in the Far East, North America and Europe

customers’ financial condition and maintains an allowance for uncollectible accounts receivable based upon the expected collectibility
of all accounts receivable. Allowance for uncollectible accounts receivable was $0 and $105,000 at December 31, 2006 and 2005,
respectively. Uncollectible amount of $65,000 was written off in 2006. No amounts were written off in 2005 and 2004.

Note 11: Commitments and Contingencies

The Company leases its facilities under non−cancelable operating leases that expire in 2007 through 2010. Rent expense was
approximately $699,000, $797,000, and $1,157,000, for the years ended December 31, 2006, 2005, and 2004, respectively. The leases
provide for monthly payments and are being charged to operations ratably over the lease terms. In addition to the minimum lease
payments, the Company is responsible for property taxes, insurance and certain other operating costs. Future minimum lease payments
under the non−cancelable operating leases as of December 31, 2006 are as follows (in thousands):

There were no contingent liabilities as of December 31, 2006. In July 2005, one of the Company’s customers filed a claim
concerning excess verification costs incurred by the customer in implementing a custom design for 1T−SRAM memory technology
under a licensing contract. The claim was settled in December 2005 with a net−down of $304,000 in accounts receivable and
contingent liability. There was no contingent liability as of December 31, 2005, however, the Company has given up the right to
receive $71,000 in future royalties from this customer, which was fully offset by the running royalties received during 2006.

Legal Matters

On March 31, 2004, UniRAM Technology, Inc. filed a complaint against us in the United States District Court for the Northern

District of California, alleging trade secret misappropriation and patent infringement. Subsequent to March 31, 2004, UniRAM
amended its complaint twice to add TSMC as a defendant and additional allegations to the suit, and to drop all infringement claims for
one of the two patents identified in the initial complaint. On October 24, 2006, the Company settled all outstanding litigation with
UniRAM Technology, Inc. related to the trade secret misappropriation and patent infringement suit filed in 2004 by UniRAM. Under
the settlement agreement, the companies agreed to dismiss all outstanding claims and counterclaims with prejudice. The Company
paid UniRAM $2.4 million, and received a complete release of all claims as well as a future fully paid license for itself and all of its
licensees to UniRAM’s relevant intellectual property.

From time to time the Company may be subject to legal proceedings and claims in the ordinary course of business. These claims,

even if not meritorious, could result in the expenditure of significant financial resources and diversion of management efforts.

MOSYS, INC.
CHANGE−IN−CONTROL AGREEMENT

THIS CHANGE−IN−CONTROL AGREEMENT (this “Agreement”), made and entered into as of October 6, 2006, by and

between Mosys, Inc., a Delaware corporation (“MoSys”), and Raj Singh (the “Executive”).

WHEREAS, MoSys considers it essential to its best interests to foster the continued employment of key management personnel
and recognizes the distraction and disruption that the possibility of a Change−in−Control (as defined in Section 1(d) below) may raise
to the detriment of MoSys and its stockholders; and

WHEREAS, MoSys has determined to take appropriate steps to reinforce and encourage the continued attention and dedication of

key management personnel to their assigned duties in the face of a possible Change−in−Control;

NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein, MoSys and the Executive

hereby agree as follows:

1.             DEFINITIONS

(a)           “Base Salary” shall mean the annual salary of the Executive at the time of termination of his employment within the

application of this Agreement.

(b)           “Beneficiary” shall mean (i) the person or persons named by the Executive, by notice to MoSys, to receive any
compensation or benefit payable under this Agreement or (ii) in the event of his death, if no such person is named and survives the

EXHIBIT A
RELEASE AGREEMENT

In consideration of the benefits I will receive under Monolithic System Technology, Inc.’s Change−in−Control Agreement, I

hereby release, acquit and forever discharge Monolithic System Technology, Inc. (the “Company”), its parents, subsidiaries,
predecessors, successors and affiliates, and each of their respective officers, directors, agents, servants, employees, attorneys
shareholders, and assigns (the “Released Parties”), of and from any and all claims, liabilities, demands, causes of action, costs,
expenses, attorneys’ fees, damages, indemnities and obligations of every kind and nature, in law, equity, or otherwise, known and
unknown, suspected and unsuspected, disclosed and undisclosed, arising out of or in any way related to agreements, events, acts or
conduct at any time prior to and including the date I sign this Release Agreement. This release of claims includes, but is not limited to:

• 

• 

• 

• 

any and all claims and demands directly or indirectly arising out of or in any way connected with my employment with the
Company or the termination of that employment, including, but not limited to, claims, demands or agreements related to
salary, bonuses, commissions, vacation pay, personal time off, fringe benefits, expense reimbursements, sabbatical benefits,
severance benefits, stock, stock options, any other ownership or equity interest in the Company, or any other form of
compensation or benefit;
claims pursuant to any federal, state or local law, statute, common law or cause of action including, but not limited to,
Title VII of the federal Civil Rights Act of 1964, as amended, or any other statute, agreement or source of law, the federal
Age Discrimination in Employment Act of 1967, as amended (“ADEA”), the federal Americans with Disabilities Act of
1990, the Family and Medical Leave Act, the Employee Retirement Income Security Act, the Equal Pay Act, the Worker
Adjustment and Retraining Notification Act, the California Fair Employment and Housing Act, as amended, and the
California Labor Code;
all tort law claims, including claims for fraud, misrepresentation, defamation, libel, emotional distress and breach of the
implied covenant of good faith and fair dealing; and
all claims arising under contract law, or the law of wrongful discharge, discrimination or harassment.

I represent that I have no lawsuits, claims or actions pending in my name, or on behalf of any other person or entity, against any of
the Released Parties. I agree that in the event I bring a claim covered by this release in which I seek damages against the Company or
in the event I seek to recover against the Company in any claims brought by a governmental agency on my behalf, this Agreement
shall serve as a complete defense to such claims.

ADEA Waiver and Release:  I acknowledge that I am knowingly and voluntarily waiving and releasing any rights I may have
under ADEA. I also acknowledge that the consideration given for the waiver and release herein is in addition to anything of value to
which I was already entitled. I further acknowledge that I have been advised by this writing, as required by the ADEA, that: (a) my
waiver and release do not apply to any rights or claims that may arise after

Source: MoSys, Inc., 10−K, March 13, 2007

the execution date of this Agreement; (b) I have been advised hereby that I have the right to consult with an attorney prior to executing
this Agreement; (c) I have 21 days from the date I receive this Agreement to consider this Agreement (although I voluntarily may
choose to execute this Agreement earlier); (d) I have seven days following the execution of this Agreement to revoke the Agreement;
and (e) this Agreement shall not be effective until the later of (i) the date upon which the revocation period has expired, which shall be
the eighth day after I execute this Agreement, or (ii) the date I return this Agreement, fully executed, to the Company.

I acknowledge that for this Release Agreement to be effective, I must sign and return it to the Company within 21 days after the

date I receive it and I must not revoke it at any time during the above−referenced seven−day revocation period.

I acknowledge that I have read and understand Section 1542 of the California Civil Code which reads as follows: “A general

release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release,
which if known by him must have materially affected his settlement with the debtor.” I hereby expressly waive and relinquish all
rights and benefits under that section and any law of any jurisdiction of similar effect with respect to my release of any unknown or
unsuspected claims I may have against any of the Released Parties.

I understand that this Release Agreement, together with the Change−in−Control Agreement, constitutes the complete, final and
exclusive embodiment of the entire agreement between the Company and me with regard to the subject matter hereof. I am not relying
on any promise or representation by the Company that is not expressly stated in this Release Agreement.
