                                     PART I

ITEM 1. DESCRIPTION OF BUSINESS

THE COMPANY

        Patriot Scientific Corporation (the "Company" or "Patriot") was
organized under Delaware law on March 24, 1992 as the successor by merger to
Patriot Financial Corporation, a Colorado corporation incorporated on June 10,
1987. Its address is 10989 Via Frontera, San Diego, California 92127, and its
telephone number is (619) 674-5000. The Company's home page can be located on
the World Wide Web at http://www.ptsc.com.

        The Company is engaged in the development and marketing of patented
microprocessor technology and high speed data communication products. The
Company also owns and is developing innovative radar and antenna technology. The
Company's strategy is to exploit its technologies through product sales,
licensing, strategic alliances or government contracting.

        In 1997, the Company emerged from the development stage primarily as a
result of the acquisition of Metacomp Inc. ("Metacomp") as discussed further
below under the caption "Background." There can be no assurance the Company can
achieve profitable operations, and the Company may need additional financial
resources during the next twelve months.

BACKGROUND

        In February of 1989, the Company completed its initial public offering
pursuant to a Registration Statement on Form S-18 under the Securities Act of
1933 (the "Act"), raising gross proceeds of $50,000 and net proceeds of
approximately $28,640 upon the sale of 2,500,000 units at $.02 per unit. Each
unit sold in the public offering consisted of one Common Share and one Class A
common stock purchase warrant exercisable to acquire one share of common stock
and one Class B common stock purchase warrant. All Class A and Class B warrants
have since been exercised or have lapsed.

        On August 10, 1989, the Company acquired its GPR technology from the
inventor, Mr. Elwood G. Norris, now the Company's Chairman. The details of that
acquisition and certain related agreements are described in more detail in
"Certain Transactions" below. A description of the GPR technology, certain
information about the industry generally, and the Company's operational plans
are discussed below under the caption "Business".

        On May 12, 1992, the Company redomiciled itself from Colorado to
Delaware by merging into a wholly-owned Delaware subsidiary (Patriot Scientific
Corporation) organized for that purpose. The reincorporation resulted in a
combination (reverse split) of each three of the Company's common shares, par
value $.00001, into one share of the Delaware corporation, par value $.00001.
The reincorporation also effected a change in the Company's charter and bylaws
and a name change to Patriot Scientific Corporation.

        In May of 1993, the Company registered under the Act a total of
7,631,606 shares issuable upon the exercise of outstanding Class A and Class B
common stock purchase warrants. The Company received net proceeds of 


                                       6
<PAGE>   7

$3,343,915 upon the exercise of those warrants and the issuance of 7,538,102
common shares. None of such warrants remain outstanding.

        Effective May 31, 1994, pursuant to an Assets Purchase Agreement and
Plan of Reorganization ("nanoTronics Agreement") between the Company,
nanoTronics Corporation ("nanoTronics") located in Eagle Point, Oregon and
Helmut Falk ("Falk"), the Company issued a total of 10,000,000 restricted common
shares to nanoTronics to acquire certain microprocessor technology of
nanoTronics. The technology acquired ("ShBoom technology") is being used to
develop a sophisticated yet low cost microprocessor. 5,000,000 of the shares
were issued on a non-contingent basis, and the remaining 5,000,000 shares were
subject to the terms of an earnout escrow arrangement of which 500,000 shares
have been released from escrow as of May 31, 1998. See "Business."

        Effective December 26, 1996, pursuant to an exchange offer and letter of
transmittal, the Company acquired 96.9% of the outstanding shares of Metacomp, a
California corporation, from 56 shareholders in exchange for the issuance of
1,272,068 shares of the Company's common stock. Based on the closing price of
the Company's common stock of $1.375 on the date of the acquisition, the price
of the acquisition was $1,749,094. This business combination was accounted for
as a pooling-of-interests. Sixteen persons who held an aggregate of 1,059,574
common shares issued in the Metacomp acquisition, agreed to a lock-up
arrangement limiting sales by each holder to 5% of their shares per month
through December 1998.

                                    BUSINESS

ORGANIZATION AND CORPORATE DEVELOPMENT

        The Company's business is managed as three major technologies/divisions
(1) PSC1000 microprocessor technology, (2) high-speed data communications and
(3) radar and antennae technology. The Company anticipates that the PSC1000
family of microprocessors will benefit the radar and antennae technology and the
high-speed data communications division, in that the PSC1000 microprocessor may
provide a low-cost, high performance alternative to existing microprocessors.
Due to the Company's small size and staffing overlaps among the divisions,
certain personnel work on more than one of the technologies from time to time.
As a result of the business combination with Metacomp and initial revenue from
the sale of microprocessors, the Company is no longer a development stage
company.

        During fiscal years 1998 and 1997, the Company focused the majority of
its efforts on the PSC1000 and high-speed data communications technologies. The
PSC1000 technology and the Company's initial microprocessors, the PSC1000
family, are targeted for the embedded controller and Java language processor
marketplaces.

        In reviewing markets for the PSC1000 technology, the Company identified
within the communications markets a possible opportunity for its ISDN product.
During fiscal 1995, the Company initiated the development of a computer
compatible plug-in card allowing high-speed, cost-effective digital ISDN access
to the Internet and other networks. This product, the CyberShark high-speed data
modem, is being marketed to Internet providers, distributors, value-added
resellers and original equipment manufacturers and has been integrated with
Metacomp's high speed data communication products.

        In 1994, during the course of the Company's GPR development, the Company
identified certain antenna technology employing ionized gas as the conducting
element. The Company has obtained two government contracts to evaluate and
characterize the gas antenna technology. Management believes this technology
could have applications in commercial as well as military communications and
radar. However, the Company has no present plans to devote significant resources
to this technology other than from outside funding.

INTERNET GROWTH AND THE EMERGENCE OF THE JAVA PROGRAMMING LANGUAGE

        The Internet is a rapidly growing global web of computer networks.
Developed over 25 years ago, this "network of networks" allows any computer
connected to the Internet to talk to any other using the Internet Protocol. The
Internet provides organizations and individuals with new means to conduct
business. Commercial uses of the Internet include business-to-business and
business-to-consumer transactions, product marketing, advertising,
entertainment, electronic publishing, electronic services and customer support.
The Company believes that 


                                       7
<PAGE>   8

organizations will also increasingly use the Internet and private Intranet
networks to improve communications, distribute information, lower operating
costs and change operations.

        Use of the Internet has grown rapidly since its commercialization in the
early 1990's, impacting computer hardware, software and peripheral industries.
The rapid growth in popularity of the Internet is in part due to continuing
penetration of computers and modems into U.S. households, growth of the
informational, entertainment and commercial applications and resources of the
Internet and the growing awareness of such resources among individuals, and
increasing availability of user-friendly navigational and utility tools which
enable easier access to the Internet's resources.

        The growth of the Internet and corporate Intranets is creating a demand
for hardware, software and peripherals. The large and growing number of users
connecting to the Internet is creating a demand for traditional analog and ISDN
digital modems, such as the Company's CyberShark, and other high speed data
communication devices. New software, such as Java, is emerging to serve the
requirements of Internet users.

        The Java programming language was originally developed for personal
digital assistant devices (PDA's) and television set top boxes. It was formally
announced as an object-oriented language for the Internet in May 1995 by Sun
Microsystems Inc. It was launched on the Internet through the free offer of a
Java programming software developer's kit and Java related browser, a form of
Internet software interface. A large number of major computer, software, browser
and on-line service provider companies have licensed the Java language.
Accordingly, although no assurance can be given, Java appears to be emerging as
the fundamental platform for distributed, network-centric applications. There is
a growing list of Java applications, or applets, now available on the Internet
that not only enhance Web pages but also perform many functions of traditional
computer software programs. The Company's PSC1000 technology lends itself to
potential acceptance in this market.

        With Java, data and programs do not have to be stored on the user's
computer, but can reside anywhere on the Internet to be called upon as needed,
sometimes referred to as just-in-time software. Among its various attributes,
two key features of Java are (1) its ability to run on a variety of computer
operating systems thus avoiding the problem of incompatibility across networks,
and (2) security, because Java enables the construction of virus-free,
tamper-free systems by using resource-access control and public-key encryption.
Because of Java's useful features, it may also become a popular programming
language for embedded applications.

        Since Java is designed to run on multiple types of devices and operating
systems, it allows developers to write a program once for many types of
operating systems, instead of having to write new versions for each type. Java
does this by interpreting a program's commands into something a particular type
of computer can understand. This interpretive design runs programs slower than
if they were tailored for each type of computer and is resulting in a need for
specialized microprocessors and compilers to increase Java's speed.

        The growth of Java is causing a number of companies to consider it as a
basis for a new style of computing tailored to the Internet and not encumbered
by the limitations of, or requiring, traditional operating systems (such as
Microsoft DOS or Windows, UNIX or Macintosh). The concept is to design
inexpensive access devices to communicate via the Internet. Public announcements
of such devices have been made by major companies such as Oracle and Sun
Microsystems Inc. There can be no assurance that any such devices will become
successful or that any will use the PSC1000 technology in the future.

SHBOOM MICROPROCESSOR TECHNOLOGY

        GENERAL BACKGROUND. nanoTronics Corporation was formed in 1991 and
acquired the ShBoom technology, a base technology for an advanced microprocessor
integrated on a single chip. nanoTronics subsequently engaged in substantial
technical development and fabricated a first-generation microprocessor in early
1994.

        Since the acquisition of the ShBoom technology from nanoTronics,
effective May 31, 1994, the Company has been engaged in correcting errors in the
microprocessor design, adding additional technical features to further modernize
the design, and improving and testing the new design. The Company obtained the
first run of prototype microprocessors in late May 1996, a 0.8 micron
microprocessor. The next generation of the PSC1000 family was a 0.5 micron
microprocessor that was delivered in September 1997. The 0.5 micron
microprocessor is being employed in 


                                       8
<PAGE>   9

demonstrations for prospective customers and is currently being shipped to
customers as an embedded microprocessor. A 0.35 micron production microprocessor
will be available for sale featuring a reduced size and improved performance.
Future enhancements and generations or modifications of microprocessors
employing the ShBoom technology and architecture are contemplated by the
Company.

        INDUSTRY BACKGROUND. The semiconductor logic market has three major
sectors: (1) Standard Logic Products, (2) Application Specific Standard Products
(ASSPs), and (3) Application Specific Integrated Circuit (ASICs). Standard logic
products, such as the Intel 80X86 and Motorola 680X0 microprocessor families,
are neither application nor customer specific. They are intended to be utilized
by a large group of systems designers for a broad range of applications. Because
they are designed to be used in a broad array of applications, they may not be
cost effective for specific applications. ASICs are designed to meet the
specific application of one customer. While cost effective for that application,
ASICs require large sales volumes of that application to recover their
development costs. ASSPs are developed for one or more applications but are not
generally proprietary to one customer. Examples of ASSP applications include
modems, cellular telephones, wireless communications, multimedia applications,
facsimile machines and local area networks. The Company's microprocessor is
designed to be combined with application-specific software to serve as an
embedded control product for the ASSP market sector.

        ASSPs are typically used in embedded control systems by manufacturers to
provide an integrated solution for application specific control requirements.
Such systems usually contain a microprocessor or microcontroller, logic
circuitry, memory and input/output circuitry. Electronic system manufacturers
combine one or more of these elements to fit a specific application. The
microprocessor provides the intelligence to control the system. The logic
circuitry provides functions specific to the end application. The input/output
circuitry may also be application specific or an industry standard component.
The memory element, if not on the microprocessor, is usually a standard product
used to store program instructions and data. In the past, these functions have
been executed through multiple integrated circuits assembled on a printed
circuit board. The requirements for reduced cost and improved system performance
have created market opportunities for semiconductor suppliers to integrate some
or all of these elements into a single ASSP microprocessor or chip set, such as
the ShBoom-architecture PSC1000 family. The PSC1000 family provides close
integration of the microprocessor and input/output function with the logic
circuitry, thereby providing an advanced ASSP.

        Embedded control systems enable manufacturers to differentiate their
products, replace less efficient electromechanical control devices, add product
functionality and reduce product costs. In addition, embedded control systems
facilitate the emergence of completely new classes of products. Embedded control
systems have been incorporated into thousands of products and subassemblies
worldwide including automotive systems, remote controls, appliances, portable
computers and devices, cordless and cellular telephones, motor controls and many
other systems.

        Microcontrollers are generally available in 4-bit through 32-bit
architectures, which refers to the amount of data they can process. Although
4-bit microcontrollers are relatively inexpensive, typically less than $1.00
each, they lack performance and features but account for more than 40% of
worldwide microcontroller volume. Also, in general use today are 8-bit
architectures, generally costing $1.00 to $10.00 each and accounting for an
additional 40% of worldwide microcontroller volume. To date 16-bit and 32-bit
architectures, with typical costs of over $10.00 each, have offered very high
performance, but are generally considered to be expensive for high-volume
embedded control applications. The use of 16-bit and 32-bit architectures offers
fewer internal limitations, making programming easier and providing higher
performance. Although generally more expensive per unit and requiring more
support logic and memory, these devices offer many advantages for more
sophisticated embedded control systems.

        Electronic system designers, driven by competitive market forces, seek
semiconductor products with more intelligence, functionality and control that
can be used to reduce system costs and improve performance. For these needs, the
ShBoom architecture was designed to be a sophisticated 32-bit RISC (reduced
instruction set computer) microprocessor with advanced features, including the
most commonly needed support logic, but at a low cost; thereby providing
improved performance to existing embedded control applications and creating the
opportunity for the development of new, cost-effective applications.

        TECHNOLOGY DESCRIPTION. Conventional high-performance microprocessors
are register-based with large register sets. These registers are directly
addressable storage locations requiring a complex architecture that consumes


                                       9
<PAGE>   10

costly silicon. This conventional architecture provides processing power for
computer applications but complicates and slows the execution of individual
instructions and increases silicon size, thereby increasing chip cost.

        The Company's technology is fundamentally different from most other
microprocessors because it is stack-oriented, in that the data is stored in
groups. The Company's microprocessor further employs certain features of both
register and stack designs. The resultant merged stack-register architecture
improves program execution for a wide range of embedded applications. The
Company's design combines two processors in one highly-integrated package, a
microprocessing unit (MPU) for performing conventional processing tasks, and an
input-output processor (IOP) for performing input-output functions. The IOP
replaces many dedicated peripheral functions supplied with other processors. The
microprocessor's design simplifies the manipulation of data. ShBoom's
architecture employs instructions that are shrunk from 32-bits to 8-bits. This
simplified instruction scheme improves execution speed for computer
instructions. The Company's architecture incorporates many on-chip system
functions, thus eliminating the requirement of support microprocessors and
reducing system cost to users.

        The 0.8 micron microprocessor has been designed to operate at a speed of
50Mhz; the 0.5 micron microprocessor at a speed of 100Mhz; and the 0.35 micron
microprocessor at 150 MHz . They are all compatible with a wide range of memory
technology from low cost DRAM (dynamic random-access memory) to high speed SRAM
(static random access memory). The microprocessors can be packaged in various
surface-mount and die-form packaging. There can be no assurance that the
designed speed will be achieved with production microprocessors or future
versions or that all of the desired functions will perform as anticipated.

        The ShBoom technology is not designed or targeted to compete with
high-end processors for use in personal computers. It is targeted for embedded
control applications. The Company believes that the above advanced features
differentiate the PSC1000 family from other 8-bit to 32-bit microprocessors
targeted for embedded control applications. Considering the reduced requirement
for support microprocessors, the PSC1000 family is intended to be available at a
high volume price that should be price competitive with high-end 8-bit
microprocessor and general 16-bit microprocessor systems but with higher
performance (speed and functional capability). The PSC1000 family has been
designed to allow high-speed and high-yield fabrication using generally
available wafer fabrication technology and facilities.

        THE PSC1000 MICROPROCESSOR AS A JAVA PROCESSOR. The Company believes the
PSC1000 microprocessor architecture is capable of being a highly efficient and
cost-effective Java programming language processor. This is because Java is
designed to run on a stack-oriented architecture and the stack-oriented ShBoom
architecture is very efficient for executing the virtual stack machine internal
to Java. Many Java bytecodes (byte or 8-bit sized operation codes or
instructions) require only a single 8-bit PSC1000 family instruction to be
executed, providing a performance advantage over other more expensive processors
that require six or more 32-bit instructions to do the same task. This is an
important advantage for executing Java programs with increased speed and reduced
code size enabling lower system memory costs. In addition, the incorporation of
many on-chip system functions is expected to allow the PSC1000 family to perform
most of the other functions required of an Internet computer device or Java
accelerator, thereby eliminating components. Since Internet computers are
designed to be inexpensive appliances for Internet access, cost, speed and
performance are expected to be key requirements for designers. The Company
believes the ShBoom technology can compete favorably on the basis of such
requirements, although there can be no assurance the Company can successfully
exploit Java related applications or that competitors will not create superior
Java processors.

        The Company has ported the Java operating environment to the PSC1000
family, which currently utilizes the C programming language for software
support. The Company is a licensee of Sun Microsystems Inc. which enables the
Company to develop and distribute products based on Sun's JavaOS Technology. The
Company recently exercised an option to license from Sun Microsystems Inc.,
Personal Java, a platform on which to run Java applications; licensed from Wind
River VXWorks, an operating system; and entered into a relationship with Forth
Inc. whereby Forth will provide software support and operating system
development tools for the Forth Programming language. Successful implementation
of this software is expected to produce one of the best price performance
microprocessors available in silicon supporting the Java virtual machine and
embedded applications. The Company believes that, if the implementation is
successfully completed, the PSC1000 family will be competitive with Java
microprocessors announced by competitors. However, there can be no assurance of
successful implementation of this package of software or of a market for a
PSC1000 family Java microprocessor.


                                       10
<PAGE>   11

        STAGE OF DEVELOPMENT. An initial first-generation production of wafers
was fabricated in early 1994 at a contract fabrication facility using 6-inch
wafers employing 0.8 micron double-metal CMOS technology. After the May 31, 1994
acquisition, the Company improved the original design, added new features and
performed simulations and tests of the improved designs. In October 1995, a run
of six wafers of second-generation microprocessors (of the same CMOS technology)
were fabricated by a contract fabrication facility. Subsequently, the Company
tested the resultant microprocessors, while completing a C computer language
compiler and preparing application development tools. The compiler and
application development tools are necessary to enable system designers to
program the PSC1000 family for specific applications. The Company made
corrections to the design from testing the first run and produced an additional
run of second-generation microprocessors from existing wafers. Second run
microprocessors (the 0.8 micron microprocessor) were received in May 1996. In
July 1996, the Company commenced employing these microprocessors in
demonstration boards for use by developers and prospective customers and
licensees.

        In December 1996, the Company commenced development efforts aimed at
producing a 0.5 micron microprocessor based on the PSC1000 technology. A
reduction to 0.5 micron double-metal CMOS technology improved operating speed,
reduced power requirements, reduced physical size and reduced fabrication cost
resulting in improved cost-performance over the 0.8 micron microprocessor and
competitors. In May 1998, the Company commenced production run of a 0.35 micron
microprocessor that management anticipates will further increase operating speed
and cost-performance over the previous generations of the PSC1000 family of
microprocessors.

        At each stage of development, microprocessors require extensive testing
to ascertain performance limitations and the extent and nature of errors (bugs),
if any. When significant limitations or errors are discovered, additional rounds
of design modifications and fabrication are required prior to having functional
and demonstrable microprocessors for prospective customers and licensees.
Although the 0.5 micron microprocessor version has been sent to prospective
customers in anticipation of production quantity orders, there can be no
assurance that the Company, during its continued testing of these products, will
not identify errors requiring additional rounds of design and fabrication prior
to commercial production. Additional delays could have an adverse effect on the
marketability of the Company's technology and the Company's financial condition.

        The Company has developed marketing materials, product manuals and
application development tools for use by prospective licensees and customers.
The manuals and tools are necessary to enable system designers to quickly and
easily program the PSC1000 family for specific applications.

        Management believes that the PSC1000 family is ready for licensing or
sale and that any additional changes encountered in current testing will be
minor and can be made during initial production runs of PSC1000 family
microprocessors for customers, when and if orders are obtained. Management also
believes the ShBoom core technology is ready for licensing for use by others to
develop custom multiple function microprocessors. Certain initial licensing
discussions and customer demonstrations have commenced. However, there can be no
assurance of market acceptance of the PSC1000 family or the Company's ShBoom
technology.

        In April 1998 the Company received its first major contract
incorporating the PSC1000 microprocessor. The PSC1000 will be used as a main
component on a digital video disk (DVD) controller card used in a kiosk
application for the travel industry. The value of the contract was in excess of
$3 million with deliveries scheduled for fiscal year 1999.

        BUSINESS STRATEGY. The increasing demand for embedded control has made
the market for microcontrollers one of the largest segments of the semiconductor
logic market. The Company's strategy does not entail competing directly with
suppliers who have multiple microprocessors in various market segments, but on
identifying certain market niches that would benefit from the advanced features
of the ShBoom-architecture embedded microprocessors and its corresponding low
system cost.

        Because of the above factors and competitive conditions, management
intends to focus the majority of its initial efforts on the Java processor
business, a new but highly-competitive field without an established base of
microprocessors and for which management believes the ShBoom architecture has
certain technical advantages.

        Management believes that the ShBoom architecture is suited for
controller applications requiring high-performance and low system cost, such as
kiosks, laser printers, dot-matrix printers, video terminals, robotics, motion


                                       11
<PAGE>   12

controllers, industrial controllers, digital communication devices, video games,
cable and satellite modems and TV set-top boxes. The Company expects that early
licensing of the technology and product applications will focus on embedded
control.

        The Company has appointed eight international distributors for foreign
markets. The Company has a full-time Vice President of Sales and Marketing to
lead marketing of the PSC1000 family.

        Management believes the appropriate approach for the Company initially
lies in a balanced effort of cultivating licensees and developing specific
product enhancement partnerships, producing OEM products, developing innovative
in-house products, and providing technical support to third parties on a
contract basis. The overall balance of these approaches will be monitored and
modified as management attempts to ascertain and capitalize on the highly
dynamic and competitive embedded microprocessor market. There can be no
assurance that the Company can successfully exploit its ShBoom microprocessor
technology.

        Subject to the availability of financial and personnel resources, while
the Company is commercializing the PSC1000 family and the ShBoom core
technology, the Company's strategy is to also design and develop future versions
of the microprocessor with more demanding sub-micron technology and with more
features. However, the Company's resources are limited, and there can be no
assurance the Company will be able to continue microprocessor enhancement.

        Initial fabrications of the 0.8 micron and 0.5 micron processors were
performed by contract fabrication facilities. The 0.35 micron microprocessor has
been delivered for fabrication to a contract fabrication facility that has
agreed to provide production quantities for the Company's customers. There can
be no assurance fabrication facilities will be available to produce the PSC1000
family in the future. However, since there are a large number of fabrication
facilities with the capability to produce the PSC1000 family of microprocessors,
management believes microprocessors can be produced on a contract basis.
Industry shortages of fabrication facilities that may exist and are predicted to
exist in the future are generally limited to the more demanding architectures.
If a shortage of fabrication facilities develop, it could have a material
adverse effect on the Company's profitability.

        COMPETITION. The semiconductor industry is intensely competitive and has
been characterized by price erosion, rapid technological change and foreign
competition in many markets. The industry consists of major domestic and
international semiconductor companies, most of which have greater financial,
technical, marketing, distribution, development and other resources than the
Company. The market for microprocessors and for embedded control applications is
at least as competitive.

        While the Company's strategy is to target high-volume licensees and chip
customers requiring more sophisticated but low-cost devices, the Company can
still expect significant competition. The Company may also elect to develop
embedded control system products utilizing the ShBoom architecture for itself or
by contract for other manufacturers.

        The Company expects that the PSC1000 family, if successfully
commercialized in the embedded controller market, will compete with a variety of
16/32-bit microprocessors including ARM, MIPS and the PowerPC. As a Java
processor, the Company expects its PSC1000 family will compete with a broad
range of microprocessors including licensees of Sun Microsystems, Inc.'s
PicoJava. These companies have significantly greater resources than the Company.

        A new entrant, such as the Company, is at a competitive disadvantage
compared to these and other established producers due to a number of factors,
including the lack of product performance experience, lack of experience by
customers in using application development systems, no record of technical
service and support, and limited marketing and sales capabilities.

HIGH SPEED DATA COMMUNICATIONS

        GENERAL BACKGROUND. Starting in fiscal 1995 the Company initiated the
development of a computer compatible plug-in card allowing high-speed,
cost-effective digital ISDN access to the Internet and other networks. In
December 1996, the Company acquired 96.9% of Metacomp to create a communications
division including 


                                       12
<PAGE>   13

engineering, assembly, marketing and distribution. The acquisition of Metacomp
expanded the product line and added a high-speed data communications revenue and
customer base. High-speed data communication revenues accounted for
substantially all of the Company's revenues for the fiscal year ended May 31,
1998.

        Metacomp, founded in 1978, is a high technology company that designs,
assembles, and sells a wide range of high performance data and
telecommunications solutions for wide area networking and high speed data
communications requirements.

        The business combination with Metacomp was treated as a
pooling-of-interests, and the Metacomp product line was combined with the
Company's ISDN product to form the communications division.

        ISDN AND DIGITAL COMMUNICATIONS DESCRIPTION. The Integrated Services
Digital Network (ISDN) is a set of digital transmission protocols that virtually
all of the world's communications carriers have adopted as a standard. ISDN
brings the digital network to the individual user by turning the twisted-pair
copper telephone line into a high-speed, high-capacity ISDN line with the
capacity for two transmissions (one voice, fax or computer conversations and one
data conversation) to happen at the same time. Further, up to eight separate
devices (telephones, computers, fax machines, etc.) can be connected to the same
ISDN line and each given separate telephone numbers. In many home and business
applications, the use of an ISDN line provides dramatically increased speed and,
by allowing multiple uses of one line, improved economics over multiple lines.
ISDN service is easily connected by local telephone companies.

        In addition to ISDN products, the Company's communications division is
also engaged in providing solutions in wide area networking for both personal
computers as well as higher speed industrial systems using VME interfaces.

        MAJOR COMMUNICATIONS DIVISION PRODUCTS. The Company has a line of ISDN
interface products for high speed, cost effective digital communications through
telephone networks.
These products include:

        CyberShark Family
      CyberShark - This low-cost Basic Rate ISDN (BRI) adapter card for ISA bus
      is targeted to allow small businesses and telecommuters to access
      corporate networks and the Internet via ISDN. The card includes an analog
      phone jack that allows the user to connect his existing analog phone or
      fax machines for simultaneous voice conversation.

      CyberShark/HSET - This BRI adapter card for ISA bus is designed to be used
      with a headset/handset used by distributed call centers and remote agents.
      It offers access to the D channel and supports domestic as well as
      European telco switches. Drivers for Windows/95, Windows/NT, and Linux are
      available.

      CyberShark/PRI - This Primary Rate ISDN (PRI) adapter card for ISA bus
      provides intelligent support of up to 23 simultaneous digital connections
      offered by the 23B+D interface. An optional MVIP Bus interface on board
      allows easy integration into third-party voice, analog modem, or video
      codec boards. Other downloadable firmware engines are available to support
      T1/Fractional-T1, E1 and ETSI PRI services. Drivers for Windows/NT are
      available.

        FlagShip Family
      FlagShip/PRI-2 - This newest member of the Company's ISDN product family
      is a dual-span PRI adapter card for PCI bus that supports up to 46
      simultaneous digital connections. The MVIP Bus interface is standard.
      Firmware engines to support T1/Fractional-T1, E1 and ETSI PRI services
      will be offered. A driver for Windows/NT is available.

      VME Product Line - The Company also offers a line of intelligent high
      speed communications engines in a VME form factor. Some of our customers
      for these products include the military as well as large satellite based
      data communications companies.

      ATcomm2/4 Product Line - The Company also markets an intelligent two or
      four channel product that is used around the world for high speed data
      communications.


                                       13
<PAGE>   14

      Other - The communications division also obtains revenue from providing
      contract engineering and software development for customers. The Company
      from time to time is able to retain a proprietary interest in developed
      products and in such circumstances retains a license/royalty interest.

        The Company's product strategy is to continue to provide data
communication solutions through improving current products and introducing new
products. The Company has three research and development personnel assigned to
high speed data communication product development and enhancement. These
activities include customer specific development for OEMs, VARs and others as
well as new proprietary product development and enhancement.

        PRODUCTION AND MARKETING STRATEGY. The Company's strategy is to have its
high-speed data communication products manufactured on a sub-contract basis
with, in some instances, final assembly at the Company's facility. Products are
tested and distributed by the Company. An in-house marketing staff manages the
marketing of the Company's high-speed data communications products. The
Company's telecommunication products and ISDN products (other than CyberShark)
are targeted for OEMs, systems integrators, VARs and sophisticated end users.

        COMPETITION. There are a number of ISDN board-level products competitive
to CyberShark offered by competitors including NetAccess, ISDN-tek, Inc., Zyxel,
Digi International and U.S. Robotics. These companies have substantially greater
resources than the Company. Although not all of these companies offer PC plug-in
card terminal adapters directly competitive with the Company's product, there
can be no assurance additional direct competitors will not introduce competitive
products.

        The Company believes its products are competitive on both features and
price with the products currently in the marketplace or those known by
management to have been announced. ISDN modems also compete with traditional
analog modems and with other interface technologies such as cable modems.
Accordingly this field is subject to rapid technological change and fierce
competition.

        The Company does not believe it can avail itself of patent protection on
most of its high-speed data communication products in development. The Company
does rely on trade secrets and copyrights to protect its high-speed data
communications products.



RADAR AND ANTENNA TECHNOLOGY

        BACKGROUND. During the period from 1980-1983, Mr. Norris, Chairman of
the Company, developed a technique employing microwave radiation to penetrate
the earth's surface. This radar technology relates to "ground penetrating radar"
or "GPR." GPR technology is one of many of a family of geophysical tools and
sensing technologies that include seismic, electromagnetics, gravity, borehole
sampling and other techniques. GPR is a technique for producing profiles of
subsurface strata and features by emitting radar waves and recording the
reflected signals.

        The Company commenced active development of its GPR technology in April
1992. By May 1993 the Company was able to demonstrate the sensing, processing
and crude visualization of images from its technology, and by May 1994 the
Company had completed its prototype device. Since May 1994 the Company has
focused its efforts and limited financial resources on the PSC1000 technology
and communication products, effectively suspending development and most
marketing efforts related to GPR.

        GAS ANTENNA TECHNOLOGY. In September 1994, the Company filed a patent
application on certain gas antenna technology invented during its radar
development. Immediately upon receiving notice of allowance in June, 1995, the
invention was classified secret by the U.S. Department of Commerce at the
request of a defense agency. This technology is not currently used in and is
separate and apart from the GPR technology, although it may be employed in the
GPR technology in the future.

        In January 1996, the Company filed an application seeking
declassification of the technology, and in June 1996, was advised that
de-classification had been approved and the U.S. patent issued in January 1997.
The de-classification allows the Company to exploit the technology for both
governmental and commercial purposes.


                                       14
<PAGE>   15

        The Company's gas antenna technology employs ionized gas as the
conducting element of an antenna. This is a fundamental change from traditional
antenna design that generally employs solid wires as the conducting element.
Management believes ionized gas is an efficient conducting element with a number
of advantages. Since the gas is ionized only for the precise time of
transmission or reception, ringing and associated effects of solid wire antenna
design is reduced. The design allows for extremely short pulses, important to
many forms of digital communication and radar. The design further provides the
opportunity to construct an antenna that can be dynamically reconfigured for
frequency, direction, bandwidth, gain and beamwidth. Management believes
antennas can be designed that are low in weight, small in size and with lower
power consumption than traditional solid wire antennas.

        The Company has obtained two government contracts to evaluate a
prototype of the gas antenna technology. There can be no assurance that the
Company will obtain additional development funds or that it can successfully
exploit this technology.

        GPR TECHNOLOGY DESCRIPTION. The Company has developed sensors (wave
generators and antennae) and techniques for the processing, conversion,
compression, storage, and visualization (collectively, computer processing) of
GPR data. The Company has developed proprietary techniques for wave generation
and proprietary antennae for the sending and receiving of data. The Company uses
proprietary methods to capture and process returned signals.

        The Company has assembled a mobile prototype version of its GPR
technology. This prototype encompasses a blending of laboratory equipment (with
internal software and hardware custom configured and modified to function as
desired) and specialized components including antennae, power generators and
amplifiers. The prototype has demonstrated the ability to penetrate multiple
solid objects (walls and barriers) and identify return signals from additional
objects such as walls, persons and manmade barriers. In certain ground strata,
the Company has been able to resolve objects of six inch size at approximately
ten feet in depth. The Company's device does not require contact with the ground
providing enhanced mobility, extended area coverage and the ability to look
sideways (for example through walls and in mine shafts).

        The Company has one U.S. patent on antenna technology for its GPR. Other
aspects of the GPR system are maintained as trade secrets, although additional
patent applications may be filed in the future.

        STAGE OF DEVELOPMENT OF GPR TECHNOLOGY. The Company's prototype system
is used for limited prospective customer and user evaluations of the technology.
The Company has demonstrated using the technology to detect plastic mines, side
viewing through walls and solid structures for detection of bodies or other
objects, and viewing of plastic pipes and other underground objects.

        The Company believes most prospective users will require more
specifically tailored equipment and multiple devices. Commercialization of the
GPR technology will require additional development to improve visualization
software and to replace the current system with specifically designed components
to minimize cost and weight and improve portability.

        There can be no assurance that a commercially viable device will or can
be produced, and the Company has no existing users or customers. There can be no
assurance any prospective users will select the Company's device over
competitive devices (See "Competition").

        BUSINESS STRATEGY. The Company has limited resources to pursue further
development to commercialize a GPR system for the above markets and to exploit
the gas antenna technology. The Company's strategy is to use its GPR and gas
antenna prototypes to demonstrate to prospective users the Company's
capabilities and to seek partnering arrangements to develop custom commercial
devices for specific applications. The Company's marketing activities to date
have been very limited and are focused primarily towards governmental agencies.
The strategy is to seek sponsorship to assist in further development and
commercialization of the present technology. There can be no assurance that the
Company can obtain any outside assistance or successfully complete development
and commercially exploit its GPR or gas antenna technology.

        COMPETITION. The segment of the electronics industry that involves the
manufacture and sale of GPR equipment is not large or cohesive enough to be
referred to as an "industry" but is more a specialized subset of geophysical
tools that include seismic equipment and other geophysical and scientific
instruments. The antenna 


                                       15
<PAGE>   16

industry is very competitive and consists of a large number of companies with
substantial resources, a large installed base, established government and
commercial relationships, and large research and development staffs. It is
possible that any such technology owned or developed by others may be further
advanced than the Company's technology.

        The Company has not yet developed a commercially marketable prototype of
its GPR or gas antenna technology. Most of the Company's potential competitors
are actively engaged in operations and have had time to develop product
recognition and market share and have greater financial and other resources than
the Company.

RESEARCH AND DEVELOPMENT

        The Company's current development efforts are focused on the
introduction of the PSC1000-family microprocessor and high speed data
communication products. The development of the Company's technologies has taken
longer than anticipated by management and could be subject to additional delays.
Therefore, there can be no assurance of timely or successful marketing of the
PSC1000-family or of continued market acceptance of existing and proposed high
speed data communication products.

        The Company incurred research and development expenditures of $1,607,828
and $1,367,937 for the fiscal years ended May 31, 1998 and 1997, respectively.
The majority of the Company's expenditures in fiscal 1998 and 1997 have been
expended on its PSC1000 and high-speed data communications technologies. To
date, the Company has expensed internal software development costs as incurred.
The Company believes that technical advances are essential to its success and
expects that it will continue to expend substantial funds on research and
development of its technologies; however, there can be no assurance that such
research and development efforts will result in the design and development of
competitive technologies in a timely manner.

LICENSES, PATENTS, TRADE SECRETS AND OTHER PROPRIETARY RIGHTS

        The Company relies on a combination of patents, copyright and trademark
laws, trade secrets, software security measures, license agreements and
nondisclosure agreements to protect its proprietary technologies. The Company
pursues a policy of seeking the issuance of patents that it considers important
to its business to protect inventions and technology that support the Company's
microprocessor and radar and antennae technologies.

        The Company has four U.S. patents issued and has three U.S. patents
pending, most dating back to 1989, on the ShBoom microprocessor technology. The
Company has one ShBoom technology patent pending in five European countries and
Japan and may file additional applications under international treaties
depending on an evaluation of the costs and anticipated benefits that may be
obtained by expanding possible patent coverage.

        In addition to such factors as innovation, technological expertise and
experienced personnel, the Company believes that a strong patent position is
becoming increasingly important to compete effectively in the semiconductor
industry. It may become necessary or desirable in the future for the Company to
obtain patent and technology licenses from other companies relating to certain
technology that may be employed in future products or processes. To date, the
Company has not received notices of claimed infringement of patents with any
existing processes or products; but, due to the nature of the industry, the
Company may receive such claims in the future. Likewise, the Company believes
that it may have claims against other semiconductor companies should certain of
its pending patents be favorably granted, but there can be no assurance thereof
nor any assurance that the Company could successfully exploit any potential
patent claims against larger competitors.

        The Company acquired the basic ShBoom technology from nanoTronics
Corporation in return for 10,000,000 shares of the Company's common stock in
1994. The Company does not believe it is obligated to pay any royalties on
aspects of the ShBoom technology specified in prior agreements between
nanoTronics Corporation and a previous inventor. The Company believes, should
there be royalties due to the previous inventor, that the obligation is that of
nanoTronics. The Company has been informed by nanoTronics that a tender of a
part of the consideration paid by the Company to nanoTronics for the basic
ShBoom technology has initially been rejected by the inventor and that the
inventor has proposed that he is entitled to royalties and the basic technology
be returned by nanoTronics and licensed back to the Company. nanoTronics has
rejected this proposal and the Company and nanoTronics are continuing
discussions with the inventor in an effort to resolve these issues. However, if
it is ultimately determined that the 


                                       16
<PAGE>   17
inventor is entitled to royalties, the Company could be subject to
indemnification claims by nanoTronics of up to $1,250,000 pursuant to its
agreement with nanoTronics. See Item 12, "Certain Relationships and Related
Transactions," for further discussion.

        Pursuant to the Assets Purchase Agreement and Plan of Reorganization
(Agreement) between the Company, nanoTronics and Falk, the Company was the
recipient of a number of warranties and indemnities. The Company believes
nanoTronics has been or is in the process of liquidation and due to Mr. Falk's
death in July 1995, the Company may be limited in its ability to obtain
satisfaction should it have any future claims pursuant to the Agreement.

        The Company has one U.S. patent on its gas antenna technology. The
Company's ability to obtain protection in other countries may be limited due to
the time delay caused by the secrecy order. The Company also has one U.S. patent
on antennae technology directly related to its GPR technology. No foreign
application was made. Although plans in this regard are not definite, the
Company's intention is to apply for patents only as to selected aspects of the
Company's GPR and gas antenna technology in order to reduce the risk of
infringement or duplication by competitors. Considering the rapid advancements
in the field of electronics generally, the Company believes that its interests
will best be served by treating as trade secrets non-patented components or
instrumentation groups used in some of its technologies. There are a large
number of patents owned by others in the radar and antenna fields generally and
in the field of GPR specifically. Accordingly, although the Company is not aware
of any possible infringement and has not received any notices of claimed
infringement, the Company may receive claims in the future.

        A third party has licensed certain ISDN software technology to the
Company. In addition to the protection afforded the Company through the ISDN
technology licenses, the Company has created its own software and hardware
designs and uses copyright, trade secrets, software security measures and
nondisclosure agreements to protect its proprietary products, technology and
software. The Company has one U.S. patent on its high-speed data communication
technology. Despite the Company's precautions, it may be possible for
unauthorized third parties to copy aspects of, or otherwise obtain and use, the
Company's high-speed data communication technology and software without
authorization. In addition, the Company cannot be certain that others will not
develop substantially equivalent or superseding proprietary technology thereby
substantially reducing the value of the Company's proprietary rights.

        Metacomp has licensed a family of interface chips to Sipex Corporation
under a royalty agreement providing for a minimum of $50,000 per year through
calendar year 1998 after which time it becomes a royalty free license.

        There can be no assurance that any patents will issue from pending or
future applications or that any patents that are issued will provide meaningful
protection or other commercial advantages to the Company. Although the Company
intends to protect its rights vigorously, there can be no assurance that these
measures will be successful.

        The Company generally requires all its employees and consultants,
including its management, to sign a non-disclosure and invention assignment
agreement upon employment with the Company.

MARKETING AND DISTRIBUTION

        The Company's products are marketed through a combination of a direct
sales force and distributors. Approximate sales by principal geographic area (as
a percentage of sales) were for fiscal years ended:

        All operating assets are located within the United States. While sales
to certain geographic areas generally vary from year to year, the Company does
not expect that changes in the geographic composition of sales will have a
material adverse effect on operations.

DEPENDENCE UPON SINGLE CUSTOMERS

        Ten percent (10%) or more of the Company's consolidated net sales for
the fiscal years indicated were derived from shipments to the following
customers:

</TABLE>

        While the level of shipments to individual customers generally varies
from year to year, the Company does not expect that changes in customer
composition will have a material adverse effect on operations.

EMPLOYEES

        The Company currently has twenty full-time and two part-time personnel.
Ten full-time persons are employed in research and development, four full-time
persons are engaged in manufacturing and assembly, two full-time persons are
engaged in marketing and four full-time and two part-time persons are engaged in
general and administrative activities. These persons include Mr. Norris and Mr.
Putnam, who only devote a part of their available time to the affairs of the
Company. The Company also engages additional consultants and part-time persons
as needed from time to time.

        The Company's future success depends in significant part upon the
continued service of its key technical and senior management personnel. The
competition for highly qualified personnel is intense, and there can be no
assurance that the Company will be able to retain its key managerial and
technical employees or that it will be able to attract and retain additional
highly qualified technical and managerial personnel in the future. None of the
Company's employees is represented by a labor union and it considers its
relations with its employees to be good. None of the Company's employees is
covered by key man life insurance policies.

GOVERNMENT REGULATION

        To the Company's knowledge, its products are not subject to governmental
regulation by any federal, state or local agencies that would affect the
manufacture, sale or use of its products. The Company cannot, of course, predict
what sort of regulations of this type may be imposed in the future but does not
anticipate any unusual difficulties in complying with governmental regulations
which may be adopted in the future. If any technical or rating standards of
professional bodies (such as UL or SAE) are applicable to any equipment or
components produced by the Company, it is management's intention to comply with
such standards.

        The Company's proposed GPR device and antenna technology uses microwave
radio waves. The use of such waves are regulated by the Federal Communications
Commission ("FCC") and, should the Company elect to sell such devices, their
operation would have to meet applicable FCC rules and regulations. Management
does not believe that the operation of the GPR prototype on contract analysis
projects requires FCC approval.

        The Company has not incurred costs associated with environmental laws
and does not anticipate such laws will have any significant effect on the future
business of the Company.

ITEM 2. DESCRIPTION OF PROPERTY

        Effective January, 1997 the Company merged its operations with Metacomp
and moved its principal executive and operating office to space leased by
Metacomp at 10989 Via Frontera, San Diego, California. This space contains
approximately 10,000 square feet of space, including approximately 7,500 square
feet of improved space for office and technical personnel and approximately
2,500 square feet of unimproved warehouse space. Management believes this
facility is adequate for the present needs of the Company and Metacomp for at
least the next twelve months. Four research and development personnel are
located in the Los Gatos, California area, and one research and development
person is located in the Austin, Texas area. Each of these individuals
telecommutes from their respective home offices with the San Diego facility.

ITEM 3. LEGAL PROCEEDINGS

        The Company is not party to any material pending legal proceedings.

        The Company had approximately 226 shareholders of record as of May 31,
1998. At August 14, 1998, there were 38,248,110 shares of Common Stock issued
and outstanding. The Company has never paid a cash dividend on its Common Stock
and does not expect to pay one in the foreseeable future.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

        The Company's results of operations have and may continue to be subject
to significant variations. The results for a particular period may vary due to a
number of factors, including the overall state of the semiconductor and
communications segments of the economy, the development status of and demand for
the Company's products, 


                                       19
<PAGE>   20

economic conditions in the Company's markets, the timing of orders, the timing
of expenditures in anticipation of future sales, the mix of products sold by the
Company, the introduction of new products and product enhancements by the
Company or its competitors and pricing and other competitive conditions.

As described in Note 1 to the consolidated financial statements of the Company,
effective December 26, 1996, the Company acquired 96.9% of the common stock of
Metacomp. The business combination was accounted for as a pooling of interests
and, accordingly, the Company's financial statements have been presented to
include the results of Metacomp as though the business combination occurred as
of June 1, 1995. In addition, Metacomp changed its fiscal year-end from July 31
to May 31 to conform to the Company's fiscal year-end. Based on the difference
in fiscal year-ends, results of operations for the two months ended July 31,
1996 were included in both years ended May 31, 1997 and 1996.

RESULTS OF OPERATIONS

Net sales. Total net sales for the fiscal year ended May 31, 1998 increased 3.0%
to $1,902,874 from $1,847,421 for the fiscal year ended May 31, 1997. This
increase was due primarily to the initial sales for the microprocessor and
radar/antenna product lines.

Cost of sales. Cost of sales as a percentage of net sales increased to 61.2% in
fiscal 1998 compared to 54.3% in fiscal 1997. This increase in the cost of sales
percentage was a result of a write down in inventory values related to the
obsolescence of components and finished parts of the older product lines being
phased out.

Research and development expenses increased 17.5% from $1,367,937 in fiscal 1997
to $1,607,828 for fiscal 1998. This increase was due primarily to an increase in
licensed software support and update fees.

Selling, general and administrative expenses increased 43.3% from $1,723,751 in
fiscal 1997 to $2,470,937 in fiscal 1998. This increase was due primarily to the
costs of two financings, which financings were in the total amount of
$3,000,000, an increase in personnel costs related to the Company's addition of
two executives, one marketing and one financial, the compensation costs related
to the release from escrow of 500,000 shares of common stock as discussed in
Note 4 to the consolidated financial statements, and the increase in marketing
costs related to introducing the Company's products to the marketplace.

Amortization of purchased ShBoom technology was $612,333 for fiscal 1997. The
technology was totally amortized during fiscal year 1997 and, accordingly, there
was no corresponding expense for the comparable period of fiscal year 1998.

Other income (expense) was significantly higher for fiscal 1998 as a result of
the non-cash interest related to the discount on the convertible term debentures
as discussed in Note 5 to the consolidated financial statements and the interest
on the same notes.

An extraordinary income item of $1,779,457 was included in fiscal 1997. This
item was the result of the discharge of debts by Metacomp in July, 1996 as a
result of their successful completion of their Chapter 11 case.


LIQUIDITY AND CAPITAL RESOURCES

        At May 31, 1998, working capital was $1,011,329 and cash and cash
equivalents totaled $602,456. The Company has funded its operations primarily
through the issuance of securities. Cash and cash equivalents increased $124,781
during fiscal year 1998. Net cash used in operating activities of $2,423,080 and
additions to property and equipment of $417,225 were offset by the net proceeds
from a new issuance of convertible debt in the amount of $2,720,000 and the
proceeds from stock option exercises of $247,807. Of the convertible debt
amount, $2,445,000 was subsequently converted into common shares of the Company.

        The Company's liquidity for the next twelve months is anticipated to be
supplemented by sales, including sales derived from a major contract for a DVD
controller card in a kiosk application, and licensing of PSC1000
microprocessors.


                                       20
<PAGE>   21

        The Company anticipates that it may require additional equipment,
fabrication, components and supplies during the next twelve months to continue
development of the Company's technologies. Product introductions such as those
currently underway for communication products and the PSC1000 microprocessor may
require significant inventory and other expenditures not presently estimable by
management. Further, if expanded development is commenced or new generations of
microprocessors or radar are accelerated beyond current plans, additional
expenditures, not currently estimable by management, may be required. It is
possible therefore, that higher levels of expenditures may be required than
currently contemplated by management resulting from changes in development plans
or as required to support new developments or commercialization activities or
otherwise.

        Based on the potential rate of cash operating expenditures and current
plans, management anticipates the cash requirements for the next twelve will be
satisfied by improved product sales, the sale of additional Company equity
securities, debt financing and/or the sale or licensing of certain of the
Company's technologies. There can be no assurance that any future funds required
will be generated from operations or from the aforementioned or other potential
sources. The lack of additional capital could force the Company to substantially
curtail or cease operations and would therefore have a material adverse effect
on the Company's business. Further, there can be no assurance that any such
required funds, if available, will be available on attractive terms or that they
will not have a significantly dilutive effect on existing shareholders of the
Company.

TAX LOSS CARRYFORWARDS

        As of May 31, 1998, the Company has approximately $8,677,000 of tax loss
carryforwards. A valuation allowance has been recorded for the net deferred tax
asset of $4,131,000 arising primarily from tax loss carryforwards because
management can not determine that it is more likely than not that the deferred
tax asset will not be realized. See Note 8 to the Consolidated Financial
Statements.

YEAR 2000 COMPLIANCE

        The Company, like most owners of computer software, will be required to
modify significant portions of its software so that it will function properly in
the year 2000. Preliminary estimates of the total costs to be incurred by the
Company to resolve this problem range from $20,000 to $30,000. Since the Company
mainly uses third party "off-the-shelf" software, it does not anticipate a
problem in resolving the year 2000 problem in a timely manner. Maintenance or
modification costs will be expensed as incurred, while the costs of new software
will be capitalized and amortized over the software's useful life.

NEW ACCOUNTING PRONOUNCEMENTS

        The Financial Accounting Standards Board ("FASB") has issued Statement
of Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive
Income" and SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information." SFAS No. 130 establishes standards for reporting and
display of comprehensive income, its components and accumulated balances.
Comprehensive income is defined to include all changes in equity except those
resulting from investments by owners and distributions to owners. Among other
disclosures, SFAS No. 130 requires that all items that are required to be
recognized under current accounting standards as components of comprehensive
income be reported in a financial statement that displays with the same
prominence as other financial statements. SFAS No. 131 supersedes SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise." SFAS No. 131
establishes standards on the way that public companies report financial
information about operating segments in annual financial statements and requires
reporting of selected information about operating segments in interim financial
statements issued to the public. It also establishes standards for disclosure
regarding products and services, geographic areas and major customers. SFAS No.
131 defines operating segments as components of a company about which separate
financial information is available that is evaluated regularly by the chief
operating decision maker in deciding how to allocate resources and in assessing
performance.

        SFAS 130 and 131 are effective for financial statements for periods
beginning after December 15, 1997 and require comparative information for
earlier years to be restated. Because of the recent issuance of the standards,
management has been unable to fully evaluate the impact, if any, the standards
may have on future financial statement disclosures. Results of operations and
financial position, however, will be unaffected by implementation of the
standards.

        In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits" which standardizes the
disclosure requirements for pensions and other postretirement benefits and
requires additional information on changes in the benefit obligations and fair
values of plan assets that will facilitate financial analysis. SFAS No. 132 is
effective for years beginning after December 15, 1997 and requires comparative
information for earlier years to be restated, unless such information is not
readily available. Management believes the adoption of this statement will have
no material impact on the Company's financial statements.

        In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which requires companies to record
derivatives on the balance sheet as assets or liabilities, measured at fair
market value. Gains or losses resulting from changes in the values of those
derivatives would be accounted for depending on the use of the derivative and
whether it qualifies for hedge accounting. The key criterion for hedge
accounting is that the hedging relationship must be highly effective in
achieving offsetting changes in fair value or cash flows. SFAS No. 133 is
effective for fiscal periods beginning after June 15, 1999. Management believes
the adoption of this statement will have no material impact on the Company's
financial statements.

FOURTH QUARTER ADJUSTMENTS

The Company recorded in the fourth quarter certain adjustments relative to
non-cash interest expense related to convertible debt and associated debenture
costs and a write-down of inventory due to obsolescence amounting to an
aggregate of $2,100,000 which are discussed in Notes 5 and 6 to the
consolidated financial statements. Of the aggregate amount, $1,000,000 and
$1,100,000 related to the third and fourth quarters, respectively. The Company
plans to file an amended Form 10-QSB for the quarter ended February 28, 1998.

GENERAL CONFLICTS OF INTEREST

        Conflicts of interest now exist and will continue to exist between the
Company and certain of its officers and directors due to the fact that certain
officers and directors have other employment or business interests to which they
devote attention. The Company has not established policies or procedures for the
resolution of current or potential conflicts of interest between the Company and
its management or management-affiliated entities. There can be no assurance that
members of management will resolve all conflicts of interest in the Company's
favor.

        It is conceivable that the respective areas of interest of the Company,
ATC and NCI could overlap or conflict. The Company believes that, although each
of the three corporations is involved in the electronics industry, their
respective areas of focus, products and technology are sufficiently distinct
that no conflict in business lines or 


                                       24
<PAGE>   25

executive loyalties will result. Therefore, no steps have been taken to resolve
possible conflicts among the Company, ATC, and NCI; and any such conflicts,
should they arise, will be addressed at the appropriate time.

SPECIAL CONFLICTS OF INTEREST

        Robert Putnam also acts as Secretary of NCI and ATC. Both of these
companies are effectively controlled by Elwood Norris. The possibility exists
that these other relationships could affect Mr. Putnam's independence as an
officer of the Company.

        The Company has not provided a method of resolving these conflicts (such
as refusal from voting as directors and obtaining an independent third-party
evaluation of proposed actions) and probably will not do so, partly due to
inevitable extra expense and delay any such measures would occasion and partly
because Mr. Norris does not represent a majority of the Board of Directors and
does not control the outside directors. Mr. Norris is obligated to perform his
duties in good faith and to act in the best interest of the Company and its
shareholders, and any failure on his part to do so would constitute a breach of
his fiduciary duties and expose him to damages and other liability under
applicable law.

INDEMNIFICATION OF OFFICERS, DIRECTORS AND OTHERS

        As permitted by Delaware law, the Company's Certificate of Incorporation
provides that the Company will indemnify its officers, directors, employees and
agents against attorneys' fees and other expenses and liabilities they incur to
defend, settle or satisfy any civil or criminal action brought against them
arising out of their association with or activities on behalf of the Company
unless, in any such action, they are adjudged to have acted with gross
negligence or to have engaged in willful misconduct. The Company may also bear
the expenses of such litigation for any such persons upon their promise to repay
such sums if it is ultimately determined that they are not entitled to
indemnification. Such expenditures could be substantial and may not be recouped,
even if the Company is so entitled. Insofar as indemnification for liabilities
arising under the Securities Act of 1933 may be permitted to directors, officers
or persons controlling the Company pursuant to the foregoing provisions, the
Company has been informed that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in that
Act and may, therefore, unenforceable.

EXCLUSION OF DIRECTOR LIABILITY

        Pursuant to the General Corporation Law of Delaware, the Company's
Certificate of Incorporation excludes personal liability on the part of its
directors to the Company for monetary damages based upon any violation of their
fiduciary duties as directors, except as to liability for any breach of the duty
of loyalty, acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, acts in violation of Section 174 of
the General Corporation Law of Delaware, or any transaction from which a
director receives an improper personal benefit. This exclusion of liability does
not limit any right which a director may have to be indemnified and does not
affect any director's liability under federal or applicable state securities
laws.

COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

        Section 16(a) of the Securities Exchange Act of 1934 (the "Act")
requires the Company's officers, directors and persons who own more than 10% of
a class of the Company's securities registered under Section 12(g) of the Act to
file reports of ownership and changes in ownership with the Securities and
Exchange Commission ("SEC"). Officers, directors and greater than 10%
shareholders are required by SEC regulation to furnish the Company with copies
of all Section 16(a) forms they file.

        Based solely on its review of copies of the reports it has received from
persons required to make such filings and its own records, the Company believes
that from the period June 1, 1997 through July 15, 1998, all persons subject to
the Section 16(a) reporting requirements timely filed the required reports.

day of the fiscal year of $.75.

        The Company has not awarded stock appreciation rights to any employee of
the Company and has no long-term incentive plans, as that term is defined in SEC
regulations (other than a $50,000 demonstration bonus payable to Mr. Norris upon
successful demonstration of a prototype GPR device meeting specified performance
criteria, see "Certain Transactions").

        During the fiscal year ended May 31, 1998, pursuant to Mr. Dawson's and
Mr. Mairta's Employment Contracts, the Board of Directors of the Company
cancelled 75,000 previously granted stock options to each and reset the vesting
schedule on an additional 75,000 previously granted stock options to each as a
result of the Company not meeting certain performance goals. As a result of Mr.
Carenzo's resignation in March, 1998, 337,500 previously granted stock options
were cancelled. The Company has no defined benefit or actuarial plans covering
any person.

COMPENSATION OF DIRECTORS

        No direct or indirect remuneration has been paid or is payable by the
Company to the directors in their capacity as directors other than the granting
of stock options. It is anticipated that during the next twelve months the
Company will not pay any direct or indirect remuneration to any directors of the
Company in their capacity as directors other than in the form of stock option
grants or the reimbursement of expenses of attending directors' or committee
meetings.

EMPLOYMENT CONTRACTS

        Mr. Norris may be entitled to future compensation pursuant to agreements
described in "Certain Transactions". The Company has an employment agreement
dated November 20, 1995 and amended on July 14, 1997 with Mr. Norris, the
Company's Chairman, for a three year term providing for a base salary of
$31,500. The Company may terminate Mr. Norris' employment with or without cause,
but termination without cause (other than disability or death) would result in a
lump sum severance payment of 24 months salary. Likewise upon a change in
control, as defined in the agreement, Mr. Norris may elect to terminate
employment and obtain a lump sum severance payment of 24 months salary.

        The Company entered into an employment agreement dated as of February
23, 1998 and approved by the Company's directors on March 24, 1998, with Mr.
Lunney providing for his employment as President and CEO effective March 23,
1998. The agreement is for a three year term providing for a base salary of
$130,000 per annum for the first year with an increase in the second year to at
least $140,000 per annum. The base salary may be increased at the discretion of
the Board of Directors. The agreement provides for a guaranteed bonus of 25% at
the end of the first year or on certain changes in control as defined in the
agreement. During subsequent years, Mr. Lunney is eligible for a bonus equal to
25% of the base salary conditioned on Mr. Lunney meeting certain objectives
established by the Board of Directors. In addition, the agreement provides a
$600 per month car allowance. The Company may terminate Mr. Lunney's employment
with or without cause, but termination without cause (other than disability or
death) would result in a lump sum severance payment ranging, depending on length
of service, from six to twelve months salary plus any prorated earned bonuses.
Also, upon a change of control, as defined in the agreement, Mr. Lunney may
elect to terminate employment and obtain a lump sum severance payment equal to
the base salary for the remaining months of the agreement. The Company has
granted Mr. Lunney options to purchase 350,000 common shares, 116,667 vesting on
March 23, 1998 and the balance vesting equally at the end of twelve and
twenty-four months from the date of the agreement subject to earlier vesting in
the event of a change in control of the Company.

        The Company entered into an employment agreement dated as of July 28,
1997 and approved by the Company's directors on August 18, 1997, with Mr.
Morettini providing for his employment as Vice President of Sales and Marketing.
The agreement is for a three year term providing for a base salary of $110,000
per annum for the first year and not less than $110,000 per annum during the
second and third years of the agreement. The base salary may be increased at the
discretion of the Board of Directors. The agreement provides for a bonus up to
50% of the annual base consideration for the applicable year. The Company may
terminate Mr. Morettini's employment with or without cause, but termination
without cause (other than disability or death) would result in a lump sum
severance payment equal to four months of the then current base salary. If
within twelve months of a change in control, as defined in the agreement, Mr.
Morettini's employment is terminated for other than cause or if Mr. Morettini
refuses to accept or voluntarily resigns from a position other than a qualified
position, as that term is defined in the agreement, then he will receive a lump
sum severance payment equal to twelve months of his then current salary. Under
the agreement, the Company granted Mr. Morettini options to purchase 300,000
common shares, 30,000 vesting on July 28, 1997 and the balance vesting one-third
per year starting July 28, 1998, subject to certain performance standards.
Options may vest earlier subject to the discretion of the Board of Directors.

Officer. The agreement is for a three year term providing for a base salary of
$110,000 per annum for the first year and not less than $110,000 per annum
during the second and third years of the agreement. The base salary may be
increased at the discretion of the Board of Directors. The agreement provides
for a bonus up to 50% of the annual base consideration for the applicable year.
The Company may terminate Mr. Giffhorn's employment with or without cause, but
termination without cause (other than disability or death) would result in a
lump sum severance payment equal to four months of the then current base salary.
If within twelve months 


                                       28
<PAGE>   29

of a change in control, as defined in the agreement, Mr. Giffhorn's employment
is terminated for other than cause or if Mr. Giffhorn refuses to accept or
voluntarily resigns from a position other than a qualified position, as that
term is defined in the agreement, then he will receive a lump sum severance
payment equal to twelve months of his then current salary.

        The Company entered into an employment agreement dated January 1, 1997
with Mr. Dawson providing for his employment as Vice President and General
Manager. The agreement is for a three year term providing for a base salary of
$120,000 per year with an increase in the second and third years as recommended
by the President and Chief Executive Officer and approved by the Board of
Directors. The agreement provides for incentive bonuses in certain instances of
up to 50% of the total yearly base compensation. The Company may terminate Mr.
Dawson's employment with or without cause, but termination without cause (other
than disability or death) during either of the first two years of the agreement
would result in a lump sum severance payment equal to twelve months salary. The
Company originally granted Mr. Dawson under the agreement options to purchase
500,000 common shares, 50,000 vesting on December 26, 1996 and the balance
vesting one-third per year starting December 31, 1997 subject to certain
performance standards. As a result of not meeting the performance standards, the
Board of Directors cancelled 75,000 of such options and reset the vesting date
on an additional 75,000 options from December 31, 1997 to December 31, 1998.
Options may vest earlier subject to the discretion of the Board of Directors.

        The Company entered into an employment agreement dated January 1, 1997
with Mr. Maitra providing for his employment as Vice President of Engineering.
The agreement is for a three year term providing for a base salary of $104,400
per year with an increase in the second and third years as recommended by the
President and Chief Executive Officer and approved by the Board of Directors.
Mr. Maitra's salary was increased to $120,000 for the second year. The agreement
provides for incentive bonuses in certain instances of up to 50% of the total
yearly base compensation. The Company may terminate Mr. Maitra's employment with
or without cause, but termination without cause (other than disability or death)
during the first year of the agreement would result in a lump sum severance
payment equal to twelve months salary. The Company originally granted Mr. Maitra
under the agreement options to purchase 500,000 common shares, 50,000 vesting on
December 26, 1996 and the balance vesting one-third per year starting December
31, 1997 subject to certain performance standards. As a result of not meeting
the performance standards, the Board of Directors cancelled 75,000 of such
options and reset the vesting date on an additional 75,000 options from December
31, 1997 to December 31, 1998. Options may vest earlier subject to the
discretion of the Board of Directors.

      1 As trustee of the Helmut Falk Family Trust and executor of the Helmut
      Falk estate, Ms. Felcyn effectively controls the shares described in Notes
      2 and 3 below.

      2 These shares have been issued but are subject to an escrow arrangement
      as described in "Certain Transactions" below. The shares were originally
      issued to nanoTronics in connection with the ShBoom technology
      acquisition.

      3 These shares remain from 5,000,000 non-escrowed originally issued shares
      plus 500,000 shares released from escrow and issued to nanoTronics in
      connection with the ShBoom technology acquisition. These shares were
      subsequently transferred to the Helmut Falk Family Trust.

      4 For each of Messrs. Norris and McDaniel the amount includes 100,000
      shares, for each of Mssrs. Bernier, Dawson and Putnam the amount includes
      50,000 shares, for Mr. Maitra the amount includes 110,753 shares, and for
      Mr. Morettini the amount includes 120,000 shares issuable upon the
      exercise of immediately exercisable outstanding stock options granted
      pursuant to the 1996 and 1992 Stock Option Plans.

      5 Includes 900,000 common shares held by Sea Ltd., a corporation through
      which Mr. McDaniel may direct certain investment powers.

      6 Mr. McDaniel is pursuing a claim against the Falk estate based on a
      written agreement with Mr. Falk pursuant to which he believes he is
      entitled to 5% of Patriot common shares (representing 275,000 shares held
      outside of escrow and 225,000 shares held in escrow for a total of 500,000
      common shares) held by nanoTronics (see Notes 2 and 3). Representatives of
      nanoTronics have advised the Company that they believe Mr. McDaniel's
      claim relates only to an interest in nanoTronics and that he therefore has
      no direct interest in nanoTronics' Patriot common shares until and if the
      claim is resolved. The additional 500,000 shares claimed by Mr. McDaniel
      are not included in Mr. McDaniel's holdings described herein since he
      cannot presently exert investment or voting control over the shares and
      there can be no assurance he will prevail in his claim.

      7 Consists entirely of shares issuable upon the exercise of outstanding
      stock options.

      8 Includes 5,774,771 shares issued and outstanding and 1,393,111 shares
      issuable upon exercise of stock options.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        There were no transactions, or series of transactions, during fiscal
1997 or 1998, nor are there any currently proposed transactions, or series of
transactions, to which the Company is a party, in which the amount exceeds
$60,000, and in which to the knowledge of the Company any director, executive
officer, nominee, five percent or greater shareholder, or any member of the
immediate family of any of the foregoing persons, have or will have any direct
or indirect material interest other than described below.

        Pursuant to an Assets Purchase Agreement and Plan of Reorganization
("Purchase Agreement") dated June 22, 1994 between the Company, nanoTronics
Corporation ("nanoTronics") and Helmut Falk ("Falk"), the Company issued a total
of 10,000,000 restricted common shares to nanoTronics, 5,000,000 of which were a
contingent payment subject to the terms of an earnout escrow. These shares were
issued in consideration of technology acquired.

        nanoTronics was formed in 1991 and acquired certain base technology for
a RISC-based (Reduced Instruction Set Computing) 32-bit microprocessor
integrated on a single microprocessor with merged stack/register architecture
from the co-inventor of the technology. nanoTronics expended in excess of $1.9
million (unaudited) while engaged in further development of that technology and
produced from the basic architecture an enhanced microprocessor
(ShBoom-architecture microprocessor). In connection with the acquisition, the
Company also acquired certain fixed 


                                       31
<PAGE>   32

assets including a Sun Sparc 2 Work Station and various terminals, peripheral
devices and software. A majority of the expenditures by nanoTronics consisted of
microprocessor and related software development costs. The result of these
efforts was a successful initial fabrication of the microprocessor in early 1994
demonstrating technical feasibility of the ShBoom architecture. nanoTronics also
expended funds on the preparation and prosecution of patent applications.

        The shares were issued to nanoTronics of which Falk was the sole
shareholder. Although 4,500,000 of the shares issued remain subject to the terms
of an earnout escrow, as more fully described below, all of the shares are
issued for the purpose of dividends and voting. Prior to the transaction, Mr.
Falk was not affiliated person with the Company. At the time of issuance, the
10,000,000 common shares represented approximately 36% of the total issued and
outstanding shares of the Company.

        Although the transaction did not result in a change in a majority of the
board of directors of the Company or a change in majority stock ownership of
Company, the issuance of the new stock resulted in a large percentage ownership
controlled by one entity with the ability to have significant influence over the
Company's future affairs.

        Pursuant to the terms of the Purchase Agreement, 5,000,000 of the common
shares were issued to nanoTronics pursuant to an earnout escrow arrangement as a
contingent purchase price. The terms of the escrow arrangement, as defined in
the Purchase Agreement, provide for the release from escrow of 500,000 common
shares for each $500,000 of Patriot revenues commencing June 1, 1994 and ending
May 31, 1999. The Purchase Agreement also provides for a release of shares in
the event of other major corporate events, including a sale of substantially all
the assets of the Company, certain mergers, combinations or consolidations,
certain tender offers and upon a liquidation or dissolution. Any shares not
earned by May 31, 1999 would be canceled. The shares may be sold, assigned or
transferred within the escrow arrangement but would still be subject to the
escrow terms. As of May 31, 1998, 500,000 shares have been released from escrow,
an additional 2,000,000 shares may have been earned but remain in escrow pending
the outcome of continuing discussions between the Company, nanoTronics and one
of the co-inventors of the technology, and 2,500,000 shares are held in escrow
contingent on the future revenue of the Company.

        In March 1998, the Company received a draft complaint prepared on behalf
of the co-inventor of the ShBoom technology naming as defendants the Company,
nanoTronics, and Gloria Felcyn, as trustee of the Helmut Falk Family Trust.
Among other things, the complaint alleged that the transfer of the technology by
nanoTronics to the Company was made with an intent to defraud the co-inventor
and without receiving a reasonably equivalent value in exchange. The first cause
of action sought, among other things, a declaration from the San Diego County
Superior Court that the Company and nanoTronics are obligated to pay royalties
to the co-inventor and that the Assets Purchase Agreement was fraudulent as to
the co-inventor. The second cause of action sought rescission of the Technology
Transfer Agreement and restitution of the ShBoom technology to the co-inventor.
The third cause of action sought to impose a constructive trust on the Company
in favor of the co-inventor. The Company disputes each of these claims on the
basis that the only consideration due from nanoTronics to the co-inventor has
been tendered in full, that the Asset Purchase Agreement was not fraudulent, and
that the equitable remedies of recission and restitution are not available given
the Company's investment in the development of the ShBoom technology. The
Company continues to be liable however, under its indemnification in favor of
nanoTronics, for up to $1,250,000 of costs if a court of competent jurisdiction
determines that nanoTronics is liable to the co-inventor for cash royalties
based on sales by the Company of products incorporating the ShBoom technology.

        In April 1998, the Company, nanoTronics, and the co-inventor entered
into an agreement to toll any applicable statutes of limitations for a period of
up to one year for the purpose of attempting to resolve the claim.

        In June 1998, the Company, nanoTronics, and the co-inventor entered into
a nonbinding agreement in principle to settle the dispute in consideration of
mutual full releases and the Company assigning patents on the ShBoom technology
back to the co-inventor in exchange for the co-inventor granting a fully-paid,
worldwide, subliceneable license to use the ShBoom technology patents exclusive
in the Company's existing and future fields of use. In addition, nanoTronics
agreed to release any obligation of the Company to deliver a number of shares of
the Company's stock pursuant to the Assets Purchase Agreement, which stock will
be retired. Settlement documentation has been exchanged between the parties,
although disputes remain concerning terms contained within the documents. The
Company is unable at this time to determine whether such disputes will be
resolved.


                                       32

        The Company has granted certain registration and information rights with
respect to the shares issued to nanoTronics, such rights being assignable to
Falk and the co-inventor (who has certain rights to become a shareholder in
nanoTronics). The Company has been advised that nanoTronics has been liquidated
with the 10,000,000 shares being transferred to the Helmut Falk Family Trust
which is entitled to the same registration rights. The Company is obligated to
use its best efforts to effect a registration upon written request up to two
times subject to certain limitations. The Company is also obligated to include
the shares, subject to certain limitations, in any underwriting and in any other
registration filed by the Company. The Company registered 500,000 of these
shares on a Form SB-2 registration that became effective September 11, 1997.

        Under the terms of an Agreement to Exchange Technology for Stock dated
August 8, 1989 between Mr. Norris and the Company, Mr. Norris is entitled to a
royalty equal to two and one-half percent (2.5%) of the gross revenues received
by the Company directly or indirectly from exploitation of its GPR technology
(up to a maximum royalty of $400,000), against which an advance royalty payment
of $17,000 already has been made. Mr. Norris also is entitled to a cash bonus of
$50,000 within 45 days after the Company successfully demonstrates a working
prototype of a GPR unit meeting specified performance criteria and a request for
such bonus is made to the Board of Directors and approved.

        In June 1996, the Company appointed Compunetics Incorporated, a private
company controlled by Mr. Bernier, as its exclusive ShBoom microprocessor
representative to the three major U.S. auto producers.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors
Patriot Scientific Corporation
San Diego, California

We have audited the accompanying consolidated balance sheet of Patriot
Scientific Corporation as of May 31, 1998 and the related statements of
operations, stockholders' equity and cash flows for each of the years in the two
year period ended May 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits. The consolidated
financial statements give retroactive effect to the merger of Patriot Scientific
Corporation and Metacomp, Inc., which has been accounted for as a pooling of
interests as described in Note 1 to the consolidated financial statements. As
discussed in Note 1 to the consolidated financial statements, we did not audit
the financial statements of Metacomp, Inc., the Company's majority owned
subsidiary for its fiscal year ended July 31, 1996, of which total revenues of
$239,501 are included in the consolidated financial statements for the year
ended May 31, 1997. In addition, we did not audit the extraordinary item of
$1,741,700 as discussed in Notes 1 and 11 to the consolidated financial
statements. Those statements were audited by other auditors whose report has
been furnished to us, and our opinion, insofar as it relates to the amounts
incurred for Metacomp, Inc. for the year ended May 31, 1997 is based solely on
the report of such other auditors.

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

In our opinion, based on our audits and the report of other auditors, the
consolidated financial statements referred to above, present fairly, in all
material respects, the financial position of Patriot Scientific Corporation as
of May 31, 1998, and the results of their operations and their cash flows for
each of the years in the two year period ended May 31, 1998 in conformity with
generally accepted accounting principles.

PATRIOT SCIENTIFIC CORPORATION
SUMMARY OF ACCOUNTING POLICIES

ORGANIZATION AND BUSINESS
Patriot Scientific Corporation (the "Company") is engaged in the development and
marketing of patented microprocessor technology and high-performance high-speed
data communication products. The Company also owns and is developing innovative
radar and antenna technology.

BASIS OF PRESENTATION AND CONSOLIDATION
The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles and include the accounts of the
Company, its majority owned subsidiaries, Metacomp, Inc. ("Metacomp") and Plasma
Scientific Corporation. All material intercompany transactions and balances have
been eliminated in consolidation.

As described in Note 1, effective December 26, 1996, the Company acquired 96.9%
of the common stock of Metacomp. The business combination was accounted for as a
pooling of interests and, accordingly, the Company's financial statements have
been presented to include the results of Metacomp as though the business
combination occurred as of June 1, 1995. The minority interest is not shown
separately in the Consolidated Financial Statements as it is not material.

FINANCIAL INSTRUMENTS AND CONCENTRATIONS OF CREDIT RISK
The Company's financial instruments that are exposed to concentrations of credit
risk consist primarily of cash and cash equivalents and accounts receivable.

The Company's cash equivalents are placed in high quality money market accounts
with major financial institutions and high grade short-term commercial paper.
The investment policy limits the Company's exposure to concentrations of credit
risk. Money market accounts are federally insured; however, commercial paper is
not insured. The Company has not experienced any losses in such accounts.

Concentrations of credit risk with respect to accounts receivable are limited
due to the wide variety of customers and markets which comprise the Company's
customer base, as well as their dispersion across many different geographic
areas. The Company routinely assesses the financial strength of its customers
and, as a consequence, believes that its accounts receivable credit risk
exposure is limited. Generally, the Company does not require collateral or other
security to support customer receivables. As of May 31, 1998, the Company had
approximately 35% and 27% in accounts receivable from two customers.

The carrying amounts of financial instruments including cash and cash
equivalents, accounts receivable, accounts payable, accrued expenses, capital
leases and convertible debt approximated fair value because of the immediate or
short-term maturity of these instruments.

INVENTORIES
Inventories consist of raw materials, work in process and finished goods and are
valued at the weighted average cost method, which approximates cost on a
first-in, first-out basis, not in excess of market value.

PATRIOT SCIENTIFIC CORPORATION
SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

PROPERTY, EQUIPMENT AND DEPRECIATION
Property and equipment are stated at cost. Depreciation is computed over the
estimated useful life of three to five years using the straight line method.
Property and equipment is assessed periodically for impairment. The amount of
impairment, if any, is charged to operations.

PURCHASED TECHNOLOGY
In accordance with the provisions of Financial Accounting Standards Board
("FASB") Interpretation No. 4, "Applicability of FASB Statement No. 2 to
Business Combinations Accounted for by the Purchase Method", purchased
semiconductor microprocessor technology that is determined to have alternative
future uses is capitalized at cost. Effective June 1, 1994, the Company began
amortizing such technology using the straight-line method over its estimated
useful life of three years (See Note 4). As of May 31, 1998, the purchased
technology was fully amortized.

Purchased technology is assessed periodically for impairment. The amount of
impairment, if any, is charged to operations. The Company recovers its
investments in purchased technology based upon net cash flows from future sales
and license agreements.

PATENTS AND TRADEMARKS
Patents and trademarks are carried at cost less accumulated amortization and are
amortized over their estimated useful lives of four years. The carrying value of
patents and trademarks is periodically reviewed and impairments, if any, are
recognized when the expected future benefit to be derived from individual
intangible assets is less than its carrying value.

REVENUE RECOGNITION
Revenue is recognized upon the shipment of product to the customer. Licensing
and royalty income is recognized when earned.

RESEARCH AND DEVELOPMENT COSTS
Research and development costs are expensed as incurred.

INCOME TAXES
The Company accounts for income taxes under Statement of Financial Accounting
Standards ("SFAS") No. 109. Temporary differences are differences between the
tax basis of assets and liabilities and their reported amounts in the financial
statements that will result in taxable or deductible amounts in future years.

NET LOSS PER SHARE
At May 31, 1998, the Company implemented SFAS No. 128, "Earnings Per Share."
SFAS No. 128 provides for the calculation of "Basic" and "Diluted" earnings per
share. Basic earnings per share includes no dilution and is computed by dividing
income available to common stockholders by the weighted average number of common
shares outstanding for the period. Diluted earnings per share reflects the
potential dilution of securities that could share in the earnings of an entity,
similar to fully diluted earnings per share. All prior earnings per share data
has been restated to reflect the

PATRIOT SCIENTIFIC CORPORATION
SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

requirements of SFAS No.128. The adoption of SFAS No. 128 had no effect on the
Company's previously reported earnings per share.

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

During the quarter ended May 31, 1998, based upon information then available,
the Company revised its estimates regarding the recovery of certain inventories.
As a result, the Company increased existing reserves for obsolescence by
approximately $203,000.

STOCK OPTIONS
The Company applies Accounting Principles Board ("APB") Opinion 25, "Accounting
for Stock Issued to Employees," and related Interpretations in accounting for
all stock option plans. Under APB Opinion 25, compensation cost has been
recognized for stock options granted to employees when the option price is less
than the market price of the underlying common stock on the date of grant.

SFAS No. 123, "Accounting for Stock-Based Compensation," requires the Company to
provide pro forma information regarding net income as if compensation cost for
the Company's stock option plans had been determined in accordance with the fair
value based method prescribed in SFAS No. 123. To provide the required pro forma
information, the Company estimates the fair value of each stock option at the
grant date by using the Black-Scholes option-pricing model.

STATEMENT OF CASH FLOWS
For purposes of the statement of cash flows, the Company considers all highly
liquid investments purchased with an original maturity of three months or less
to be cash equivalents.

RECENT ACCOUNTING PRONOUNCEMENTS
The FASB has issued SFAS No. 130, "Reporting Comprehensive Income" and SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information." SFAS
No. 130 establishes standards for reporting and display of comprehensive income,
its components and accumulated balances. Comprehensive income is defined to
include all changes in equity except those resulting from investments by owner
and distributions to owners. Among other disclosures, SFAS No. 130 requires that
all items that are required to be recognized under current accounting standards
as components of comprehensive income be reported in a financial statement that
displays with the same prominence as other financial statements. SFAS No. 131
supersedes SFAS No. 14, "Financial Reporting for Segments of a Business
Enterprise." SFAS No. 131 establishes standards on the way that public companies
report financial information about operating segments in annual financial
statements and requires reporting of selected information about operating
segments in interim financial statements issued to the public. It also
establishes standards for disclosure regarding 



                                      F-10
<PAGE>   49

PATRIOT SCIENTIFIC CORPORATION
SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

products and services, geographic areas and major customers. SFAS No. 131
defines operating segments as components of a company about which separate
financial information is available that is evaluated regularly by the chief
operating decision maker in deciding how to allocate resources and in assessing
performance.

SFAS 130 and 131 are effective for financial statements for periods beginning
after December 15, 1997 and require comparative information for earlier years to
be restated. Because of the recent issuance of the standards, management has
been unable to fully evaluate the impact, if any, the standards may have on
future financial statement disclosures. Results of operations and financial
position, however, will be unaffected by implementation of these standards.

In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures about
Pensions and Other Postretirement Benefits" which standardizes the disclosure
requirements for pensions and other postretirement benefits and requires
additional information on changes in the benefit obligations and fair values of
plan assets that will facilitate financial analysis. SFAS No. 132 is effective
for years beginning after December 15, 1997 and requires comparative information
for earlier years to be restated, unless such information is not readily
available. Management believes the adoption of this statement will have no
material impact on the Company's financial statements.

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" which requires companies to record
derivatives on the balance sheet as assets or liabilities, measured at fair
market value. Gains or losses resulting from changes in the values of those
derivatives would be accounted for depending on the use of the derivative and
whether it qualifies for hedge accounting. The key criterion for hedge
accounting is that the hedging relationship must be highly effective in
achieving offsetting changes in fair value or cash flows. SFAS No. 133 is
effective for fiscal periods beginning after June 15, 1999. Management believes
the adoption of this statement will have no material impact on the Company's
financial statements.

RECLASSIFICATIONS
Certain items included in the 1997 financial statements have been reclassified
to conform to the current year presentation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ACQUISITION OF METACOMP, INC. COMMON STOCK

On December 26, 1996, the Company acquired 96.9% of the common stock of Metacomp
in exchange for 1,272,068 shares of the Company's common stock. Metacomp
designs, manufactures, and sells high-performance high-speed data communication
products. The business combination was accounted for as a pooling of interests.
Accordingly, the Company's financial statements were restated to include the
results of Metacomp for all periods presented. Metacomp's fiscal year-end was
changed from July 31 to May 31 to conform to the Company's fiscal year-end.
Based on the difference in fiscal year-ends, results of operations for the two
months ended July 31, 1996 were included in the consolidated statements of
operations for both years ended May 31, 1997 and 1996. For the two months ended
July 31, 1996, Metacomp recorded total revenues of $239,501, a net loss before
extraordinary item of $37,759, extraordinary income of $1,779,457 and net income
after extraordinary item of $1,741,700. The accompanying consolidated statements
of stockholders' equity and cash flows for the year ended May 31, 1997, have
also been adjusted to eliminate the net income after extraordinary item. The
extraordinary income was the primary source of income for these two months.

Separate net sales, net income and related per share amounts of the merged
entities through the date of the business combination are presented in the
following table. In addition, the table includes unaudited pro forma net income
and net income per share amounts as of the date of the business combination
which reflect the elimination of the nonrecurring merger costs and expenses.

4. PURCHASED TECHNOLOGY

SEMICONDUCTOR MICROPROCESSOR TECHNOLOGY

Effective May 31, 1994, the Company acquired certain proprietary semiconductor
microprocessor technology (the "ShBoom Technology") and related computer
software from a corporation in exchange for 10,000,000 restricted shares of the
Company's common stock (5,000,000 of which were originally placed in escrow
subject to release as discussed below).

PATRIOT SCIENTIFIC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

The cost of this technology of $1,875,000 was based upon the estimated current
fair market value of the 5,000,000 non-contingent shares of the Company's common
stock issued under this agreement and was amortized over its estimated useful
life of three years. The remaining 5,000,000 shares issued for this technology
were subject to an earnout escrow arrangement. As such, when the escrowed shares
are earned, they are charged to compensation in a manner similar to a variable
stock option plan. The terms of the escrow arrangement provide for the release
from escrow of 500,000 shares for each $500,000 of revenues earned by the
Company during the period from June 1, 1994 through May 31, 1999. Additionally,
this agreement also provides for the release of these shares upon the occurrence
of certain defined major corporate events. Any of the contingent shares not
released by May 31, 1999 would be returned to the Company and canceled.

During the year ended May 31, 1998, 500,000 shares were released from escrow and
$375,000 was charged to compensation costs. At May 31, 1998, 4,500,000 shares
remain in escrow of which 2,000,000 shares may have been earned but remain in
escrow pending the outcome of continuing discussions between the Company, the
seller of the ShBoom Technology and one of the co-inventors of the technology as
discussed in Note 14 to the Consolidated Financial Statements.

RADAR TECHNOLOGY

Effective August 8, 1989, the Company acquired certain proprietary ground
penetrating radar ("GPR technology") from a current director of the Company,
primarily in exchange for 5,000,000 shares of the Company's common stock. Such
shares were subject to an escrow agreement and were releaseable to the director
under various specified conditions including the Company's subsequent merger or
business combination with any third party.

As a result of the Company's acquisition of the ShBoom, these 5,000,000 shares
were released to the director and the escrow agreement was terminated. Effective
May 31, 1994, additional costs totaling $1,875,000 of this previously purchased
GPR technology was recorded as compensation expense due to the release of the
5,000,000 shares. Such cost was based upon the estimated current fair market
value of the Company's common stock.

Additionally, under the terms of the agreement to acquire the GPR technology,
the director is to be paid a royalty equal to 2.5% of all gross revenues
received from the GPR technology, up to a maximum of $400,000. The director also
is to receive a $50,000 bonus upon the successful demonstration of a working
prototype of the technology meeting specified performance criteria. As of May
31, 1998, no amounts were due under this agreement; however, an advance of
$17,000 against the royalty was paid at the inception of the agreement.

5.5% CONVERTIBLE TERM DEBENTURES

In June 1997, the Company issued to a limited number of investors for cash an
aggregate of $2,000,000 of unsecured 5% Convertible Term Debentures due June 2,
1999 ("Debentures") and Stock Purchase Warrants ("Warrants") with a right to
purchase an aggregate 611,733 shares of common stock, par value $.00001 per
share, at an exercise price of $1.69125. In November 1997,

PATRIOT SCIENTIFIC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

the Company issued to the same investors for cash an aggregate of $1,000,000 of
Debentures due June 2, 1999 and Warrants with a right to purchase an aggregate
305,867 shares of common stock, par value $.00001 per share, at an exercise
price of $1.50. The principal and interest amount of each Debenture may, at the
election of the holder, be converted in whole or in part and from time to time
into fully paid and nonassessable shares of common stock, $.00001 par value, of
the Company, at a price which is the lower of (i) $1.1646 per share or (ii)
depending on the number of days the Debentures have been held after June 2,
1997, from 75% to 91% of the average of the closing bid prices for the common
stock for the ten consecutive trading days ending on the trading day immediately
preceding such conversion date. If the Debentures have not been converted into
common shares of the Company by June 2, 1999, under certain conditions, the
Debentures will automatically be converted into shares of the common stock of
the Company. As of May 31, 1998, $2,445,000 of the Debentures and $78,335 of the
accrued interest thereon had been converted into 4,333,593 common shares of the
Company.

Convertible debt instruments which are convertible at a discount to market are
accounted for by treating such discount as additional interest expense. The
Company computed the amount of the discount based on the difference between the
conversion price and fair value of the underlying common stock on the dates the
Debentures were issued. The Company recorded $2,018,111 of additional paid-in
capital for the discount related to the embedded interest in the Debentures
during fiscal 1998. The same amount, $2,018,111, was expensed for fiscal 1998
and is included under the caption "Non-cash interest expense related to
convertible notes" in the accompanying Consolidated Statements of Operations.

The warrants to purchase 917,600 shares of common stock were valued at $544,000.
Such amount was originally recorded as a reduction of the carrying amount of the
Debentures with an offset to Paid-In Capital. The discount is amortized as
additional interest expense over the term of the Debentures. In the fourth
quarter of fiscal 1998, $496,000 had been recorded as interest expense. The
balance of $48,000 is reflected as a reduction of the Debenture balance of
$555,000.

6. STOCKHOLDERS' EQUITY

PRIVATE OFFERINGS AND WARRANTS

During fiscal 1997, a total of 154,883 shares of the Company's common stock were
issued upon the exercise of outstanding warrants which had been issued in fiscal
1996. The net proceeds from the exercise were $239,501.

During fiscal 1997, the Company issued for cash an aggregate of $1,500,000 of
unsecured 6% Convertible Subordinated Promissory Notes due September 30, 1998
("Notes"). The principal and interest amount of each Note could at the election
of the noteholder be converted one or more times into fully paid and
nonassessable shares of common stock, $.00001 par value, ("Shares") of the
Company, at a price which was the lower of (i) $2.00 per share or (ii) 80% of
the average of the five days market price prior to conversion but not less than
$0.80 per share. As of May 31, 1997, all

PATRIOT SCIENTIFIC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Notes plus accrued interest had been converted into 1,525,103 shares of common
stock of the Company.

Convertible debt instruments which are convertible at a discount to market
should be accounted for by treating such discount as additional interest
expense. The Company computed the amount of the discount based on the difference
between the conversion price and fair value of the underlying common stock on
the date the Notes were issued. In 1997, the Company recorded $375,000 of
additional paid-in capital for the discount related to the embedded interest in
the Notes. This same amount was expensed during fiscal 1997 under the caption
"Non-cash interest expense related to convertible notes" in the accompanying
Consolidated Statements of Operations.

During fiscal 1998, the Company issued warrants to purchase 1,147,600 common
shares of stock with exercise prices ranging from $1.25 to $7.50 per share. All
warrants were outstanding at May 31, 1998. Included in this amount are warrants
to purchase 917,600 common shares related to the Debentures discussed in Note 5
to the Consolidated Financial Statements. The Company valued warrants issued in
fiscal 1998 at $577,500.

Directors, options to purchase common stock of the Company at a price not less
than the fair market value of the shares on the date of grant. In the case of a
significant stockholder, the option price of the share is not less than 110
percent of the fair market value of the share on the date of grant. Any options
granted under the ISO Plan must be exercised within ten years of the date they
were granted (five years in the case of a significant stockholder).

1992 NON-STATUTORY STOCK OPTION PLAN("NSO")

The Company has an NSO Plan, expiring May 20, 2002, reserving for issuance
750,000 shares of the Company's common stock. The NSO Plan provides for grants

were granted.

1995 EMPLOYEE STOCK COMPENSATION PLAN ("ESC")

Effective October 1995, the Company adopted the ESC Plan, expiring September 30,
1998, reserving for issuance 250,000 shares of the Company's common stock. The
ESC Plan provides for compensation awards of the Company's common stock to
employees (as defined), at the discretion of the Board of Directors. During
fiscal 1997, the Company issued 22,600 shares of common stock under the Plan
recording compensation expense of $28,927 for awards valued at an estimated fair
market value of $1.28 per share. During fiscal 1998, no shares were issued under
this plan. As of May 31, 1998, 32,400 shares remain available for granting under
this plan.

1996 STOCK OPTION PLAN

Effective March 1996, the Company adopted the 1996 Stock Option Plan, which was
amended by the Stockholders in December 1997, expiring March 24, 2006, reserving
for issuance 4,000,000 shares of the Company's common stock. The 1996 Stock
Option Plan provides for grants to either full or part time employees, at the
discretion of the Board of Directors, options to purchase common stock of the
Company at a price not less than the fair market value on the date of grant for
incentive stock options or not less than 85% of the fair market value on the
date of grant for non-qualified stock options. In the case of a significant
stockholder, the option price of the share is not less than 110 percent of the
fair market value of the shares on the date of grant. Any option granted under
the 1996 Stock Option Plan must be exercised within ten years of the date they
are granted (five years in the case of a significant stockholder). During the
fiscal year ended May 31, 1997, the Company issued options to purchase 1,713,000
shares of stock under the non-qualified provisions of the plan at an exercise
price of 85% of the fair market value on the date of grant and recorded
corresponding non-cash compensation in the amount of $291,180. During the fiscal
year ended May 31, 1998, the Company issued options to purchase 1,511,000 shares
of stock at market value.

SFAS No. 123, "Accounting for Stock-Based Compensation," requires the Company to
provide pro forma information regarding net loss and net loss per share as if
compensation costs for the Company's stock option plans and other stock awards
had been determined in accordance with the fair value based method prescribed in
SFAS No. 123. The Company estimates the fair value of each stock award at the
grant date by using the Black-Scholes option-pricing model with the following
weighted-average assumptions used respectively: dividend yield of zero percent
for all years; expected volatility of 50 percent; risk-free interest rates of
5.6 to 6.1 percent; and expected lives of 3 to 5 years.

Under the accounting provisions for SFAS No. 123, the Company's net loss per
share would have been increased by the pro forma amounts indicated below:

During the initial phase-in period of SFAS 123, the effect on pro forma results
are not likely to be representative of the effects on pro forma results in
future years since options vest over several years and additional awards could
be made each year.

7.     EARNINGS (LOSS) PER SHARE

In February 1997, SFAS No. 128, "Earnings per Share," was issued, which required
the Company to change the method used to calculate earnings per share. Under
SFAS No. 128, basic earnings (loss) per share is calculated as income (loss)
available to common stockholders divided by the weighted average number of
common shares outstanding. Diluted earnings (loss) per share is calculated as
net income (loss) divided by the diluted weighted average number of common
shares. The diluted weighted average number of common shares is calculated using
the treasury stock method for common stock issuable pursuant to outstanding
stock options, common stock warrants, and debt convertible into common stock.
Common stock options of 880,989 and 1,438,980 and debt convertible into
1,748,134 and 160,118 common shares of stock were not included in diluted
earnings (loss) per share in 1998 or 1997, respectively, as the effect was
antidilutive due to the Company recording losses in each of those years.

In addition, 2,000,000 shares of common stock in diluted escrow that may have
been earned as of May 31, 1998 were not considered outstanding for diluted 
earnings (loss) per share because the Company is currently negotiating whether
they will be released. See Note 14 to the Consolidated Financial Statements.

Options and warrants to purchase 2,989,604 shares of common stock at exercise
prices from $0.80 to $7.50 per share were outstanding at May 31, 1998 but were
not included in the computation of diluted earnings (loss) per share because the
exercise prices were greater than the average market price of the common shares.
Options and warrants to purchase 822,750 shares of common stock at exercise
prices from $1.37 to $2.30 per share were outstanding at May 31, 1997 but were
not included in the computation of diluted earnings (loss) per share because the
exercise prices were greater than the average market price of the common shares.

8. INCOME TAXES     As of May 31, 1998, the net
                    deferred tax asset recorded and its
                    approximate tax effect consisted of the
                    following:

asset will be realized. No current tax provision was recorded for fiscal 1998
and 1997 due to reported losses.

At May 31, 1998, the Company has net operating loss carryforwards of
approximately $8,677,000 that expire through 2013 and are subject to certain
limitations under the Internal Revenue Code of 1986, as amended.

9.  PROFIT-SHARING PLAN

Effective July 1, 1993, the Company adopted a savings and profit-sharing plan
that allows participants to make contributions by salary reduction pursuant to
Section 401(k) of the Internal Revenue Code. At the Company's discretion, the
Company may match contributions at 20% of the employee's contribution up to 6%
of the employee's salary. The Company contributions are vested 20% per year
beginning with the first year of service. The Company's contributions to the
plan were $642 in fiscal 1997. The Company made no matching contribution in
fiscal 1998. 

10. COMMITMENT AND CAPITAL    The Company, through its subsidiary, Metacomp, 
    LEASE OBLIGATIONS         entered into an eight year operating lease for its
                              office and manufacturing facilities located in San
                              Diego, California.

                              The Company also leases a copier, computers, and 
                              test equipment at interest rates between (4-18%).

11.  EXTRAORDINARY INCOME

The extraordinary income is a gain from the discharge of debt as a result of the
completion of Metacomp's Plan of Reorganization under Chapter 11 of the U.S.
Bankruptcy Code as of July, 1996.

In 1990, Metacomp filed a Chapter 11 bankruptcy petition. In 1991, the
Bankruptcy Court confirmed Metacomp's plan of reorganization which provided for
60 monthly payments to creditors with minimum payments averaging $23,400 per
month or larger depending on operating results. As of July 1996, the unsecured
creditors were paid approximately 13% of their approved claims and the


balance was discharged. One secured creditor was scheduled to be paid in full as
part of the plan of reorganization. As of July 31, 1996, this secured creditor
had a remaining balance of $312,306. The Company paid to this secured creditor a
remaining balance of $252,306 plus accrued interest in conjunction with the
business combination with Metacomp.

13.  FOURTH QUARTER ADJUSTMENTS

The Company recorded in the fourth quarter certain adjustments relative to
non-cash interest expense related to convertible debt and associated debenture
costs and a write-down of inventory due to obsolescence amounting to an
aggregate of $2,100,000 which are discussed in Notes 5 and 6 to the Consolidated
Financial Statements. Of the aggregate amount, $1,000,000 and $1,100,000 related
to the third and fourth quarters, respectively. The Company plans to file an
amended Form 10-QSB for the quarter ended February 28, 1998.

14.  SUBSEQUENT EVENT

In June 1998, the Company, the seller of the ShBoom technology and the
co-inventor entered into a nonbinding agreement in principle to settle the
dispute in consideration of mutual releases and the Company assigning patents on
the ShBoom technology back to the co-inventor in exchange for the co-inventor
granting a fully-paid, worldwide, sublicensable license to use the ShBoom
technology patents exclusive in the Company's existing and future fields of use.
In addition, nanoTronics agreed to release any obligation of the Company to
deliver a number of shares of the Company's stock pursuant to the original
acquisition agreement as discussed in Note 4 to the Consolidated Financial
Statements. Any stock not delivered will be retired. Settlement documentation
has been exchanged between the parties, although disputes remain concerning
terms contained within the documents. The Company is unable at this time to
determine whether such disputes will be resolved. The Company's Consolidated
Financial Statements do not include any adjustments that might result from the
outcome of this uncertainty.

        FOR VALUE RECEIVED, PATRIOT SCIENTIFIC CORPORATION, a Delaware

        1.2    Prepayment at Borrower's Option.

               (a) So long as no Event of Failure shall have occurred and
provided the Borrower is not in material violation of any of its obligations
under that certain Securities Purchase Agreement, dated as of June 2, 1997,

right to prepay ("Prepayment at Borrower's Election") all or any portion of the
then outstanding Debentures (other than Debentures which are the subject of a
Notice of Conversion delivered prior to the delivery date of the Optional
Prepayment Notice (as herein defined)) for the Optional Prepayment Amount (as
herein defined), which right shall be exercisable any time during the term of
this Debenture by the Borrower in increments of Five Hundred Thousand Dollars
($500,000) (provided that such right may be exercised for less than such amount
if the outstanding principal amount of this Debenture is less than such amount
and the Company is electing to effect redemption of the full amount remaining)
by delivery of an Optional Prepayment Notice in accordance with the prepayment
procedures set forth below. Any Prepayment at Borrower's Election pursuant to
this Section 1.2 shall be made ratably among Holders in proportion to the
principal amount of Debentures then outstanding. Holders may convert all or any
part of their Debentures selected for prepayment hereunder into Common Stock at
the Conversion Price by delivering a Notice of Conversion to the Borrower at any
time prior to the Effective Time of Prepayment (as herein defined). The
"Optional Prepayment Amount" with respect to each Debenture means the greater of
(a) the Benefit of the Bargain (as herein defined) as of the delivery date of
the Optional Prepayment Notice and (b) the Applicable Prepayment Percentage (as
herein defined) multiplied by the sum of the principal amount being prepaid plus
all accrued and unpaid interest thereon and accrued and unpaid Conversion
Failure Payments (if any) through the Effective Time of Prepayment.

               (i) The "Benefit of the Bargain" means an amount equal to:

                                        A x M
                                       --
                                       CP
        where:
               "A" means the principal amount of this Debenture being prepaid
        plus all accrued and unpaid interest thereon and accrued and unpaid
        Conversion Failure Payments (if any) through the Effective Time of
        Prepayment;

               "CP" means the Conversion Price in effect on the delivery date of
        the Optional Prepayment Notice; and,

               "M" means the average Closing Bid Price of the Company's Common
        Stock during the ten trading day period ending on the day immediately
        preceding the date on which the Optional Prepayment Notice is delivered
        to Holder.

        (ii) The "Applicable Prepayment Percentage" means (A) 130% if the
        Effective Time of Prepayment is prior to the date which is 545 days
        following the First Closing Date (the "First Redemption Price
        Termination Date") and (B) 125% if the Effective Time of Prepayment
        follows the First Redemption Price Termination Date but is prior to the
        Scheduled Maturity Date.

               (b) The Borrower may not deliver an Optional Prepayment Notice to
a Holder unless on or prior to the date of delivery of such Optional Prepayment
Notice, the Borrower shall have deposited with an escrow agent reasonably
satisfactory to such Holder, as a trust fund, cash sufficient in amount to pay
all amounts to which Holders are entitled upon such prepayment pursuant to
Subsection (a) of this Section 1.2, with irrevocable instructions and authority
to such escrow agent to complete the prepayment thereof in accordance with this
Section 1.2. Any Optional Prepayment Notice delivered in accordance with the
immediately preceding sentence shall be accompanied by a statement executed by a
duly authorized officer of its escrow agent, certifying the amount of funds
which have been deposited with such transfer agent or escrow agent and that the
transfer agent or escrow agent has been instructed and agrees to act as
prepayment agent hereunder.

               (c) The Borrower shall effect the Prepayment at Borrower's
Election under this Section 1.2 by giving prior written notice (the "Optional
Prepayment Notice"), which notice may only be delivered on a business day during
the period commencing 395 days following the First Closing Date, of the date on
which such prepayment is to become effective (the "Effective Time of
Prepayment") to Holders of Debentures selected for prepayment at the address and
facsimile number of such Holder appearing in the Borrower's register for the
Debentures. The Optional Prepayment Notice shall indicate the Debentures
selected for prepayment and the Optional Prepayment Amount. The Optional
Prepayment Notice shall be deemed to have been delivered to a Holder: (i) if
such fax is received by such holder on or prior to 3:00 p.m. Chicago time, on
the time and date of transmission of Borrower's fax; and (ii) if such fax is
received by Holder after 3:00 p.m. Chicago time, on the next business day
following the date of transmission of Borrower's fax; provided that, for any
notice required under this subsection 1.2(c) to be valid, a copy of such notice
must be sent to the Holders on the same day by overnight courier.

               (d) The Optional Prepayment Amount shall be paid to each Holder
whose Debentures are being prepaid at the Effective Time of Prepayment;
provided, however, that the Borrower shall not be obligated to deliver any
portion of the Optional Prepayment Amount until either the Debentures being
prepaid are delivered to the office of the Borrower or the transfer agent as
provided in this subsection, or such Holder notifies the Borrower or the
transfer agent that such Debentures have been lost, stolen or destroyed and
delivers documentation in accordance with Section 8.8 hereof. Notwithstanding
anything herein to the contrary, in the event that the Debentures being prepaid
are not delivered to the Borrower or the transfer agent prior to the second
business day following the Effective Time of Prepayment, the prepayment of the
Debentures pursuant to this Section 1.2 shall still be deemed effective as of
the Effective Time of Prepayment and the Optional Prepayment Amount shall be
paid to each Holder whose Debentures are being prepaid by 5:00 p.m., Chicago
time, on the next business day following the date on which the Debentures are
actually delivered to the Borrower or the transfer agent.

               (e) If the Borrower fails to pay, when due and owing, any
Optional Prepayment Amount, then each Holder entitled to receive such Optional
Prepayment Amount shall have the right, at any time and from time to time, to
require the Borrower, upon written notice, to immediately convert (in accordance
with the terms of Section 3.1) any or all of the Debentures which are the
subject of Prepayment at Borrower's Election into shares of Common Stock at the
lowest Conversion Price in effect during the twenty trading days following the
Effective Time of Prepayment. In addition, if the Borrower fails to pay an
Optional Prepayment Amount when due and owing, the Borrower shall thereafter
forfeit its rights under this Article I to effect Prepayment at Borrower's
Election.

Bloomberg, the average of the bid prices of any market makers for such security
as reported in the "pink sheets" by the National Quotation Bureau, Inc. If the
Closing Bid Price cannot be calculated for such security on such date on any of

the costs of such appraisal to be borne by the Company.

               (b) "Conversion Amount" means (i) the portion of the principal

                                   ARTICLE III
                                   CONVERSION

        3.1    Conversion at the Option of the Holder. Subject to the 
limitations on conversions contained in Section 3.7 hereof, the Holder may, at
any time and from time to time, convert (an "Optional Conversion") a Conversion
Amount into a number of fully paid and nonassessable shares of Common Stock
determined by dividing such Conversion Amount by the Conversion Price.

        3.2    Mechanics of Conversion. In order to effect an Optional 
Conversion, a Holder (a "Converting Holder") shall: (x) fax (or otherwise
deliver) a copy of the fully executed Notice of Conversion to the Company for
the Common Stock and (y) surrender or cause to be surrendered, this Debenture,
duly endorsed, along with a copy of the Notice of Conversion, as soon as
practicable thereafter. Upon receipt by the Company of a facsimile copy of a
Notice of Conversion from a Converting Holder, the Company shall immediately
send, via facsimile, a confirmation to the Converting Holder stating that the
Notice of Conversion has been received, the date upon which the Company expects
to deliver the Common Stock upon conversion and the name and telephone number of
a contact person at the Company regarding the conversion.


                                     EX-13
<PAGE>   7

        3.3    Delivery of Common Stock Upon Conversion. Subject to Section 3.6
hereof, upon the delivery of a Notice of Conversion, the Company shall, not
later than the later of (a) the day that is three business days following the
Conversion Date and (b) the day that is the first business day following the
date of surrender of this Debenture (or delivery of documentation in accordance
with Section 8.8) (the "Delivery Period"), issue and deliver to the Converting
Holder (x) that number of shares of Common Stock issuable upon conversion of the
portion of this Debenture being converted and (y) a new Debenture in the form
hereof representing the balance of the principal amount hereof not being
converted, if any. Delivery under this Section may be made personally or by
reputable overnight courier.

        3.4    Taxes. The Company shall pay any and all taxes (other than 
transfer taxes) which may be imposed upon it with respect to the issuance and
delivery of the shares of Common Stock upon the conversion of this Debenture.

        3.5    No Fractional Shares. No fractional shares of Common Stock are to
be issued upon the conversion of this Debenture, but the Company shall pay a
cash adjustment in respect of any fractional share which would otherwise be
issuable in an amount equal to the same fraction of the Conversion Price of a
share of Common Stock (as determined for conversion of this Debenture into whole
shares of Common Stock).

        3.6    Conversion Disputes. In the case of any dispute with respect to a
conversion, the Company shall promptly issue such number of shares of Common
Stock as are not disputed in accordance with Sections 3.1 and 3.3 hereof. If
such dispute only involves the calculation of the Conversion Price, the Company
shall submit the disputed calculations to an independent accounting firm of
national standing (selected by the Converting Holder; provided that the
Converting Holder currently does not have a client relationship with such
accounting firm) via facsimile within two (2) business days of receipt of the
Notice of Conversion. The accountant shall audit the calculations and notify the
Company and the Converting Holder of the results no later than two (2) business
days from the date it receives the disputed calculations. The accountant's
calculation shall be deemed conclusive, absent manifest error. The Company shall
then issue the appropriate number of shares of Common Stock in accordance with
Section 3.3 above.

        3.7    Limitations on Conversions. The conversion of this Debenture 
shall be subject to the following limitations (each of which limitations shall
be applied independently):

               (a)  Holding and Increment Restrictions. No Holder may effect an
        Optional Conversion prior to the date which is 120 days following the
        First Closing Date. Optional Conversions must be effected in increments
        of Ten Thousand Dollars ($10,000); provided that Optional Conversions
        may be effected for less than such amount if the sum of all outstanding
        principal of this Debenture plus all accrued interest thereon and
        Conversion Failure Payments (if any) through the Conversion Date is less
        than such amount and the Converting Holder is electing to effect the
        Optional Conversion of the full amount remaining.

               (b)  No Five Percent Holders. Notwithstanding anything to the
        contrary contained herein, the Debentures shall not be convertible by a
        Holder to the extent (but only to the 


                                     EX-14
<PAGE>   8

        extent) that, if convertible by such Holder, such Holder would
        beneficially own in excess of 4.9% of the shares of Common Stock. To the
        extent the above limitation applies, the determination of whether
        Debentures shall be convertible (vis-a-vis other securities owned by
        such Holder) and of which Debentures shall be convertible shall be in
        the sole discretion of the Holder and submission of the Debentures for
        conversion shall be deemed to be the Holder's determination of whether
        such Debentures are convertible and of which Debentures are convertible,
        subject to such aggregate percentage limitation. No prior inability to
        convert Debentures pursuant to this paragraph shall have any effect on
        the applicability of the provisions of this subsection with respect to
        any subsequent determination of convertibility. For the purposes of this
        subsection, beneficial ownership and all calculations, including without
        limitation, with respect to calculations of percentage ownership shall
        be determined in accordance with Section 13(d) of the Securities
        Exchange Act of 1934, as amended, and Regulation 13D and G thereunder.
        The provisions of this subsection may be waived and/or implemented in a
        manner otherwise than strictly in conformity with the foregoing
        provisions of this subsection 3.7(b) with the approval of the Board of
        Directors of the Corporation and the holders of a majority in interest
        in the then outstanding Debentures and Warrants (voting together as a
        single class): (i) with respect to any matter to cure any ambiguity
        herein, to correct this subsection (or any portion thereof) which may be
        defective or inconsistent with the intended 4.9% beneficial ownership
        limitation herein contained or to make changes or supplements necessary
        or desirable to properly give effect to such 4.9% limitation; and (ii)
        with respect to any other matter, with the further consent of the
        holders of majority of the then outstanding shares of Common Stock. The
        limitations contained in this subsection shall apply to a successor
        Holder of Debenture if, and to the extent, elected by such successor
        Holder concurrently with its acquisition of such Debentures, such
        election to be promptly confirmed in writing to the Company (provided no
        transfer or series of transfers to a successor Holder or holders shall
        be used by a Holder to evade the limitations contained in this
        subsection).

        3.8.   Required Conversion at Maturity. Provided all shares of Common
Stock issuable upon conversion of all outstanding Debentures are then (i)
authorized and reserved for issuance, (ii) registered under the Securities Act
for resale by all Holders thereof and (iii) eligible to be traded on the OTC
Bulletin Board, the Nasdaq Small Cap Market ("NASDAQ"), the Nasdaq National
Market System ("NMS"), the New York Stock Exchange ("NYSE") or the American
Stock Exchange ("AMEX"), each Debenture outstanding on the Scheduled Maturity
Date automatically shall be converted into shares of Common Stock on such date
in accordance with the conversion formulas set forth in Section 3.1 (the
"Required Conversion at Maturity"). If the Required Conversion at Maturity
occurs, the Borrower and the Holders shall follow the applicable conversion
procedures set forth in Article III; provided, however, that a Notice of
Conversion shall be deemed to be delivered to the Borrower or its transfer agent
on the Scheduled Maturity Date. If Borrower fails to effect the Required
Conversion at Maturity in accordance with the terms hereof, then each Holder
shall have the right, at any time and from time to time, to require the
Borrower, upon written notice, to immediately effect a repayment of all or any
part of their Debentures (in accordance with the terms of Article VI).

                                   ARTICLE IV
                      RESERVATION OF SHARES OF COMMON STOCK


                                     EX-15
<PAGE>   9

        4.1    Reserved Amount. At Closing, the Company shall have authorized 
and reserved and keep available for issuance 4,000,000 shares of Common Stock
(the "Reserved Amount") solely for the purpose of effecting the conversion of
the Debentures and exercise of the warrants to acquire Common Stock (the
"Warrants"), in the form attached to the Securities Purchase Agreement as
Exhibit B, issued or to be issued pursuant to the terms of the Securities
Purchase Agreement (collectively, all such Debentures and Warrants, the
"Securities Purchase Agreement Securities"). The Company shall at all times
reserve and keep available out of its authorized but unissued shares of Common
Stock a sufficient number of shares of Common Stock to provide for the full
conversion of all outstanding Debentures and issuance of the shares of Common
Stock in connection therewith and the full exercise of the Warrants and issuance
of the shares of Common Stock in connection therewith.

        4.2    Share Authorization. The board of directors of the Company shall
approve and shall use its best efforts to obtain authorization by the
shareholders of the Company of an increase of the number of authorized shares of
capital stock of the Company (the "Share Authorization") to sixty million
(60,000,000) shares by the earlier of September 30, 1997 and the date of the
Company's next annual meeting of shareholders. Immediately following the Share
Authorization (as herein defined), the Reserved Amount shall be one and one-half
(1.5) times the number of shares of Common Stock issuable upon conversion of
this Debenture and exercise of the Warrants.

        4.3    Increases to Reserved Amount. Without limiting any other 
provision of this Article IV, following the Share Authorization, if the Reserved
Amount for any three (3) consecutive trading days (the last of such three (3)
trading days being the "Authorization Trigger Date") shall be less than 125% of
the number of shares of Common Stock issuable upon conversion or exercise, as he
case may be, of the Securities Purchase Agreement Securities on such trading
days, the Company shall immediately notify all Holders of such occurrence and
shall take action as soon as possible, but in any event within sixty (60) days
after an Authorization Trigger Date (including, if necessary, seeking
shareholder approval to authorize the issuance of additional shares of Common
Stock) to increase the Reserved Amount to 150% of the number of shares of Common
Stock then issuable upon conversion or exercise, as the case may be, of the
Securities Purchase Agreement Securities.

        4.4    Reduction of Reserved Amount Under Certain Circumstances. Prior 
to complete conversion of this Debenture, the Company shall not reduce the
number of shares required to be reserved for issuance under this Article IV
without the written consent of all Holders except for a reduction proportionate
to a reverse stock split effected for a business purpose other than affecting
the obligations of Borrower under this Article IV, which reverse stock split
affects all shares of Common Stock equally. Following complete conversion of
this Debenture, the Company may, with fifteen (15) days prior written notice to
Holder, reduce the Reserved Amount to 125% of the number of shares of Common
Stock issuable upon the full exercise of the Warrants; provided, however, that
the Reserved Amount shall continue to be subject to increase pursuant to Section
4.3 hereof.

        4.5    Allocation of Reserved Amount. Each increase to the Reserved 
Amount shall be allocated pro rata among the Holders based on the number of
Debentures and Warrants held by each Holder at the time of the establishment of
or increase in the Reserved Amount. In the event a Holder shall sell or
otherwise transfer any of such Holder's Debentures or Warrants, each transferee


                                     EX-16
<PAGE>   10

shall be allocated a pro rata portion of such transferor's Reserved Amount. Any
portion of the Reserved Amount which remains allocated to any person or entity
which does not hold any Debentures shall be allocated to the remaining Holders,
pro rata based on the number of Debentures and Warrants then held by such
Holders.

                                    ARTICLE V
                         FAILURE TO SATISFY CONVERSIONS

        5.1    Conversion Failure Payments. If, at any time, (x) a Holder 
submits a Notice of Conversion (or is deemed to submit such notice pursuant to
Section 3.8 hereof) and the Company fails for any reason to deliver, on or prior
to the expiration of the Delivery Period for such conversion, such number of
shares of Common Stock to which such Converting Holder is entitled upon such
conversion, or (y) the Company provides notice to Holder at any time of its
intention not to issue shares of Common Stock upon exercise by Holder of its
conversion rights in accordance with the terms of the Debentures (each of (x)
and (y) being a "Conversion Failure"), then the Company shall pay to such Holder
damages in an amount equal to the lower of: (i) the product of (A) the Damages
Amount times (B) D times (C) .01 and (ii) the highest interest rate permitted by
applicable law, where:

        "D" means the number of days beginning the date of the Conversion
Failure through and including the Cure Date with respect to such Conversion
Failure;

        "Damages Amount" means the amount of the Debenture subject to conversion
plus all accrued and unpaid interest thereon as of the first day of the
Conversion Failure.

        "Cure Date" means (i) with respect to a Conversion Failure described in
clause (x) of its definition, the date the Company effects the conversion of the
portion of this Debenture submitted for conversion and (ii) with respect to a
Conversion Failure described in clause (y) of its definition, the date the
Company undertakes in writing to issue Common Stock in satisfaction of all
conversions of Debentures in accordance with their terms.

        The payments to which a Holder shall be entitled pursuant to this
Section are referred to herein as "Conversion Failure Payments." A Holder may
elect to receive accrued Conversion Failure Payments in cash or to convert all
or any portion of such accrued Conversion Failure Payments, at any time, into
Common Stock at the lowest Conversion Price in effect during the period
beginning on the date of the Conversion Failure through the Cure Date for such
Conversion Failure. In the event a Holder elects to receive any Conversion
Failure Payments in cash, it shall so notify the Company in writing. In the
event a Holder elects to convert all or any portion of the Conversion Failure
Payments, such Holder shall indicate on a Notice of Conversion such portion of
the Conversion Failure Payments which such Holder elects to so convert and such
conversion shall otherwise be effected in accordance with the provisions of
Article III.

        5.2    Buy-In Cure. Unless a Conversion Failure described in clause (y) 
of Section 5.1 hereof has occurred with respect to such a Holder, if (i) the
Company fails for any reason to deliver during the Delivery Period shares of
Common Stock to a Holder upon a conversion of this Debenture and (ii) after the
applicable Delivery Period with respect to such conversion, a Holder 


                                     EX-17
<PAGE>   11

purchases (in an open market transaction or otherwise) shares of Common Stock to
make delivery upon a sale by a Holder of the shares of Common Stock (the "Sold
Shares") which such Holder anticipated receiving upon such conversion (a
"Buy-In"), the Company shall pay such Holder (in addition to any other remedies
available to Holder) the amount by which (x) such Holder's total purchase price
(including brokerage commission, if any) for the shares of Common Stock so
purchased exceeds (y) the net proceeds received by such Holder from the sale of
the Sold Shares. For example, if a Holder purchases shares of Common Stock
having a total purchase price of $11,000 to cover a Buy-In with respect to
shares of Common Stock sold for $10,000, the Company will be required to pay
such Holder $1,000. A Holder shall provide the Company written notification
indicating any amounts payable to Holder pursuant to this Section 5.2. The
Company shall make any payments required pursuant to this Section 5.2 in
accordance with and subject to Section 8.10.

        5.3    Adjustment to Conversion Price. If a Holder has not received
certificates for all shares of Common Stock within two business days following
the expiration of the Delivery Period with respect to a conversion of any
portion of any of such Holder's Debentures for any reason, then the Fixed
Conversion Price shall thereafter be the lesser of (i) the Fixed Conversion
Price on the Conversion Date specified in the Notice of Conversion which
resulted in the Conversion Failure and (ii) the lowest Conversion Price in
effect during the period beginning on, and including, such Conversion Date
through and including the Cure Date. If there shall occur a Conversion Failure
of the type described in clause (y) of Section 5.1, then the Fixed Conversion
Price with respect to any conversion thereafter shall be the lowest Conversion
Price in effect at any time during the period beginning on, and including, the
date of the occurrence of such Conversion Failure through and including the Cure
Date. The Fixed Conversion Price shall thereafter be subject to further
adjustment for any events described in Article VII.


                                   ARTICLE VI
                                EVENTS OF FAILURE

        6.1    Holder's Option to Demand Prepayment. Upon the occurrence of an
Event of Failure (as herein defined), each Holder shall have the right to elect
at any time and from time to time prior to the cure by Borrower of such Event of
Failure to have all or any portion of such Holder's then outstanding Debentures
prepaid by the Company for an amount equal to the Holder Demand Prepayment
Amount (as herein defined).

        (a)    The right of a Holder to elect prepayment shall be exercisable 
        upon the occurrence of an Event of Failure by such Holder in its sole
        discretion by delivery of a Demand Prepayment Notice (as herein defined)
        in accordance with the procedures set forth in this Article VI.
        Notwithstanding the exercise of such right, the Holder shall be entitled
        to exercise all other rights and remedies available under the provisions
        of this Debenture and at law or in equity.

        (b)    A Holder shall effect each demand for prepayment under this 
        Article VI by giving at least two (2) business days prior to written
        notice (the "Demand Prepayment Notice") of the date which such
        prepayment is to become effective (the "Effective Date of Demand of


                                     EX-18
<PAGE>   12

        Prepayment"), the Debentures selected for prepayment and the Holder
        Demand Prepayment Amount to the Borrower at the address and facsimile
        number provided in Section 8.2, which Demand Prepayment Notice shall be
        deemed to have been delivered on the business day after the date of
        transmission of Holder's fax (with a copy sent by overnight courier to
        the Borrower) of such notice.

        (c)    The Holder Demand Prepayment Amount shall be paid to a Holder 
        whose Debentures are being prepaid within one (1) business day following
        the Effective Date of Demand of Prepayment; provided, however, that the
        Borrower shall not be obligated to deliver any portion of the Holder
        Demand Prepayment Amount until one (1) business day following either the
        date on which the Debentures being prepaid are delivered to the office
        of the Borrower or the transfer agent, or the date on which the Holder
        notifies the Borrower or the transfer agent that such Debentures have
        been lost, stolen or destroyed and delivers the documentation required
        in accordance with Section 8.8 hereof.

        6.2    Holder Demand Prepayment Amount. The "Holder Demand Prepayment
Amount" means the greater of: (a) 1.5 times the aggregate amount of the
principal amount of this Debenture for which demand is being made (the "Stated
Value"), plus all accrued and unpaid interest thereon and accrued and unpaid
Conversion Failure Payments (if any) through the date of prepayment and (b) the
product of (1) the highest price at which the Common Stock is traded on the date
of the Event of Failure (or the most recent highest closing bid price if the
Common Stock is not traded on such date) divided by the Conversion Price as of
the date of the Event of Failure, and (2) the sum of the Stated Value plus all
accrued and unpaid interest thereon and all accrued and unpaid Conversion
Failure Payments (if any) through the date of prepayment.

        6.3    Events of Failure. An "Event of Failure" means any one of the
following:

        (a)    a Conversion Failure described in Section 5.1 hereof occurs and 
is not cured by the Company within two (2) business days after its occurrence;

        (b)    the Company fails, and such failure continues uncured for three 
(3) business days after the Company has been notified thereof in writing by a
Holder, to satisfy the requirements of Article IV hereof;

        (c)    the Company fails to maintain an effective registration statement
as required by Section 2.1 and Section 3.1 of the Registration Rights Agreement
except where such failure lasts no longer than three consecutive trading days
and is caused solely by failure of the Securities and Exchange Commission to
timely review the customary submission of or respond to the customary requests
of the Company;

        (d)    for three consecutive trading days or for an aggregate of ten 
(10) trading days in any nine (9) month period, the Common Stock (including any
of the shares of Common Stock issuable upon conversion of this Debenture and
exercise of the Warrants) is (i) suspended from trading on any of NASDAQ, NMS,
NYSE, AMEX or the OTC Bulletin Board, or (ii) is not qualified for trading on at
least one of, NASDAQ, NMS, NYSE, AMEX or the OTC Bulletin Board;


                                     EX-19
<PAGE>   13

        (e)    the Company fails, and such failure continues uncured for three 
(3) business days after the Company has been notified thereof in writing by a
Holder, to remove any restrictive legend on any certificate for any shares of
Common Stock issued to a Holder upon conversion or exercise, as the case may be,
of the Securities Purchase Agreement Securities as and when required by the
Debentures, the Warrants, the Securities Purchase Agreement or the Registration
Rights Agreement;

        (f)    the Company breaches, and such breach continues uncured for three
(3) business days after the Company has been notified thereof in writing by a
Holder, any significant covenant or other material term or condition of any
Securities Purchase Agreement Securities, the Securities Purchase Agreement or
the Registration Rights Agreement;

        (g)    any representation or warranty of the Company made herein or in 
any agreement, statement or certificate given in writing pursuant hereto or in
connection herewith (including, without limitation, the Securities Purchase
Agreement and the Registration Rights Agreement), shall be false or misleading
in any material respect when made;

        (h)    the Company or any subsidiary of the Company shall make an
assignment for the benefit of creditors, or apply for or consent to the
appointment of a receiver or trustee for it or for a substantial part of its
property or business, or such a receiver or trustee shall otherwise be
appointed; or

        (i)    bankruptcy, insolvency, reorganization or liquidation proceedings
or other proceedings for relief under any bankruptcy law or any law for the
relief of debtors shall be instituted by or against the Company or any
subsidiary of the Company (and such proceedings shall continue unstayed for
thirty (30) days).

        6.4    Failure to Pay Damages Amount. If the Company fails to pay the
Holder Demand Prepayment Amount within five (5) business days of its receipt of
a Demand Prepayment Notice, then such Holder shall have the right, at any time
and from time to time prior to the payment of the Holder Demand Prepayment
Amount, to require the Company, upon written notice, to immediately convert (in
accordance with the terms of Section 3.1) all or any portion of the Holder
Demand Prepayment Amount, into shares of Common Stock at the then current
Conversion Price, provided that if the Company has not delivered the full number
of shares of Common Stock issuable upon such conversion within two (2) business
days after Holder delivers written notice of such conversion, the Conversion
Price with respect to such Holder Demand Prepayment Amount shall thereafter be
deemed to be the lower of the Variable Conversion Price on the date of the Event
of Failure and the Variable Conversion Price on the date on which the Company
delivers to the Holder the full number of freely tradable shares of Common Stock
issuable upon such conversion. In the event the Company is not able to pay all
amounts due and payable with respect to all Debentures subject to Holder Demand
Prepayment Notices, the Company shall pay the Holders such amounts pro rata,
based on the total amounts payable to such Holder relative to the total amounts
payable to all Holders.


                                   ARTICLE VII
                       ADJUSTMENTS TO THE CONVERSION PRICE


                                     EX-20
<PAGE>   14

        The Conversion Price shall be subject to adjustment from time to time as
follows:

        7.1    Stock Splits, Stock Dividends, Etc. If at any time after the 
First Closing Date, the number of outstanding shares of Common Stock is
increased by a stock split, stock dividend, combination, reclassification or
other similar event, the Fixed Conversion Price shall be proportionately
reduced, or if the number of outstanding shares of Common Stock is decreased by
a reverse stock split, combination or reclassification of shares, or other
similar event, the Fixed Conversion Price shall be proportionately increased. In
such event, the Company shall notify the Company's transfer agent of such change
on or before the effective date thereof.


        7.2    Major Transactions. If the Company shall consolidate with or
merge into any corporation or reclassify its outstanding shares of Common Stock
(other than by way of subdivision or reduction of such shares) (each a "Major
Transaction"), then each Holder shall thereafter be entitled to receive
consideration, in exchange for such Debenture, equal to the greater of, as
determined in the sole discretion of such Holder: (i) the number of shares of
stock or securities or property of the Company, or of the entity resulting from
such consolidation or merger (the "Major Transaction Consideration"), to which a
Holder of the number of shares of Common Stock delivered upon conversion of such
Debenture would have been entitled upon such Major Transaction had the Holder of
such Debenture exercised its right of conversion (without regard to any
limitations on conversion herein contained) on the trading date immediately
preceding the public announcement of the transaction resulting in such Major
Transaction and had such Common Stock been issued and outstanding and had such
Holder been the holder of record of such Common Stock at the time of such Major
Transaction, and the Company shall make lawful provision therefor as a part of
such consolidation, merger or reclassification; and (ii) 125% of the principal
amount of such Debenture in cash. No sooner than ten (10) days nor later than
five (5) days prior to the consummation of the Major Transaction, but not prior
to the public announcement of such Major Transaction, the Company shall deliver
written notice ("Notice of Major Transaction") to each Holder, which Notice of
Major Transaction shall be deemed to have been delivered one (1) business day
after the Company's sending such notice by telecopy (provided that the Company
sends a confirming copy of such notice on the same day by overnight courier) of
such Notice of Major Transaction. Such Notice of Major Transaction shall
indicate the amount and type of the Major Transaction Consideration which such
Holder would receive under clause (i) of this Section 7.2. If the Major
Transaction Consideration does not consist entirely of United States currency,
such Holder may elect to receive United States currency in an amount equal to
the value of the Major Transaction Consideration in lieu of the Major
Transaction Consideration by delivering notice of such election to the Company
within five (5) days of the Holder's receipt of the Notice of Major Transaction.

        7.3    Adjustment Due to Distribution. If the Company shall declare or 
make any distribution of its assets (or rights to acquire its assets) to holders
of Common Stock as a partial liquidating dividend, by way of return of capital
or otherwise (including any dividend or distribution to the Company's
shareholders in cash or shares (or rights to acquire shares) of capital stock of
a subsidiary) (a "Distribution") any time after the First Closing Date, then the
Holder shall be entitled, upon any conversion of this Debenture after the date
of record for determining shareholders entitled to such Distribution, to receive
the amount of such assets (or rights) which would have been payable to the
Holder had Holder with respect to the shares of Common Stock issuable upon such


                                     EX-21
<PAGE>   15

conversion and the shares of Common Stock issuable upon exercise of the Warrants
(in each case without regard to any limitations on conversion or exercise herein
or elsewhere contained) been the holder of such shares of Common Stock on the
record date for the determination of shareholders entitled to such Distribution.

        7.4    Purchase Rights. If the Company issues any Convertible Securities
or rights to purchase stock, warrants, securities or other property (the
"Purchase Rights") pro rata to the record holders of any class of Common Stock,
then the Holders will be entitled to acquire, upon the terms applicable to such
Purchase Rights, the aggregate Purchase Rights which each Holder could have
acquired if such Holder had held the number of shares of Common Stock acquirable
upon complete conversion of this Debenture (without regard to any limitations on
conversion or exercise herein or elsewhere contained) immediately before the
date on which a record is taken for the grant, issuance or sale of such Purchase
Rights, or, if no such record is taken, the date as of which the record holders
of Common Stock are to be determined for the grants, issue or sale of such
Purchase Rights.

        7.5    No Adjustment for Certain Warrants. Anything in this Article VII 
to the contrary notwithstanding, no adjustment shall be made to the Conversion
Price upon any issuance to Swartz Investments, LLC of warrants to purchase
Common Stock in consideration of its services in connection with the Securities
Purchase Agreement and the transactions contemplated thereby so long as such
warrants are not exercisable, in the aggregate, for more than 220,000 shares of
Common Stock.

        7.6    Notices of Adjustment. Upon the occurrence of any event which
requires any adjustment of the Conversion Price, then, and in each such case,
the Company shall give notice thereof to all Holders, which notice shall state
the Conversion Price resulting from such adjustment and the increase or decrease
in the number of shares of Common Stock purchasable at such price upon
conversion, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based. Such calculation shall be certified
by the chief financial officer of the Company.


                                  ARTICLE VIII
                                  MISCELLANEOUS

        8.1    Failure or Indulgency Not Waiver. No failure or delay on the part
of a Holder in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privilege.

        8.2    Notice. Any notice herein required or permitted to be given shall
be in writing and may be personally served or delivered by courier or by
confirmed telecopy and shall be deemed to have been given at the time and date
of receipt (which shall include telephone line facsimile transmission). The
addresses for such communications shall be:

        If to any other Holder, to such address set forth under Holder's name on
the signature page hereto executed by Holder.

        8.3    Amendment Provision. Except as provided in Section 3.7(b) hereof,
this Debenture and any provision hereof may only be amended by an instrument in
writing signed by the Company and the Majority Holders. The term "Debenture" and
all references thereto, as used throughout this instrument, shall mean this
instrument as originally executed, or if later amended or supplemented, then as
so amended or supplemented.

        8.4    Assignability. This Debenture shall be binding upon the Company 
and its successors and assigns and shall inure to the benefit of each Holder and
its successors and assigns. The Holder shall notify the Company upon the
assignment of this Debenture.

        8.5    Cost of Collection. If default or failure is made in any manner 
with respect to this Debenture, the Company shall pay the Holder hereof costs of
collection, including reasonable attorneys' fees.

        8.6    Governing Law. This Debenture shall be governed by and construed 
in accordance with the laws of the State of Delaware applicable to contracts
made and to be performed in the State of Delaware. The Company irrevocably
consents to the jurisdiction of the United States federal courts located in the
County of New Castle in any suit or proceeding based on or arising under this
Agreement and irrevocably agrees that all claims in respect of such suit or
proceeding may be determined in such courts. The Company irrevocably waives the
defense of an inconvenient forum to the maintenance of such suit or proceeding.
The Company further agrees that service of process upon the Company, mailed by
first class mail shall be deemed in every respect effective service of process
upon the Company in any such suit or proceeding. Nothing herein shall affect
each Holder's right to serve process in any other manner permitted by law. The
Company agrees that a final non-appealable judgment in any such suit or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on such judgment or in any other lawful manner.

        8.7    Denominations. At the request of a Holder, upon surrender of this
Debenture, the Company shall promptly issue new Debentures in the aggregate
outstanding principal amount hereof, in the form hereof, in such denominations
as such Holder shall request.

        8.8    Lost or Stolen Debentures. Upon receipt by the Company of (i)
evidence of the loss, theft, destruction or mutilation of this Debenture and
(ii) (y) in the case of loss, theft or destruction, or an indemnity reasonably
satisfactory to the Company, or (z) in the case of mutilation, upon surrender
and cancellation of this Debenture, the Company shall execute and deliver new
Debentures, in the form hereof, in such denominations as a Holder may request.
However, the Company shall not be obligated to reissue such lost or stolen
Debentures if such Holder contemporaneously requests the Company to convert this
Debenture.


                                     EX-24
<PAGE>   18

        8.9    Statements of Available Shares. Upon request, the Company shall
deliver to a Holder a written report notifying such Holder of any occurrence
which prohibits the Company from issuing Common Stock upon any such conversion.
The report shall also specify (i) the total principal amount of all outstanding
Debentures as of the date of the request, (ii) the total number or shares of
Common Stock issued upon all conversions of Debentures through the date of the
request, (iii) the total number of shares of Common Stock issued upon exercise
of all Warrants through the date of the request, (iv) the total number of shares
of Common Stock which are reserved for issuance upon conversion of Debentures
and exercise of Warrants as of the date of the request and (v) the total number
of shares of Common Stock which may thereafter be issued by the Company upon
conversion of Debentures and exercise of Warrants before the Company would
exceed the Reserved Amount. The Company shall provide, within fifteen (15) days
after delivery to the Company of a written request by Holder, all of the
information enumerated in clauses (i) - (v) of this Section 8.9.

        8.10   Status as Debenture Holder. Upon submission of a Notice of
Conversion by Holder, the principal amount of this Debenture and the interest
thereon covered thereby shall be deemed converted into shares of Common Stock
and the holder's rights with respect thereto shall cease and terminate,
excepting only the right to receive certificates for such shares of Common Stock
and to any remedies provided herein or otherwise available at law or in equity
to Holder because of a failure by the Company to comply with the terms of this
Debenture. Notwithstanding the foregoing, if Holder has not received
certificates for all shares of Common Stock prior to the tenth (10th) business
day after the expiration of the Delivery Period with respect to a conversion for
any reason, then (unless Holder otherwise elects to retain its status as a
Holder of Common Stock) the portion of the principal amount and interest thereon
subject to such conversion shall be deemed outstanding under this Debenture and
the Company shall, as soon as practicable, return this Debenture to the Holder.
In all cases, Holder shall retain all of its rights and remedies for the
Company's failure to convert this Debenture.

        8.11   Remedies Cumulative. The remedies provided in this Debenture 
shall be cumulative and in addition to all other remedies available under this
Debenture, at law or in equity (including a decree of specific performance
and/or other injunctive relief), and nothing herein shall limit Holder's right
to pursue actual damages for any failure by the Company to comply with the terms
of this Debenture. The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to the Holder and that the
remedy at law for any such breach may be inadequate. The Company therefore
agrees, in the event of any such breach or threatened breach, the Holder shall
be entitled, in addition to all other available remedies, to an injunction
restraining any breach, with the necessity of showing economic loss and without
any bond or other security being required.

                                      * * *

Company's common stock, par value $.00001 per share (the "Common Stock"), at an
exercise price of 1.50 per share (the "Exercise Price") (equal to 125% of the
average of the Closing Bid Prices (as herein defined) of the Common Stock for
the ten (10) consecutive trading days ending on the trading day immediately
preceding the Second Closing (as defined in that certain Securities Purchase
Agreement (the "Securities Purchase Agreement") dated as of June 2, 1997 among
the Company, CC Investments, LDC and The Matthew Fund, N.V.). The number of
shares of Common Stock purchasable hereunder (the "Warrant Shares") and the
Exercise Price are subject to adjustment as provided in Section 4 hereof. The
term "Warrants" means this Warrant and the other warrants, if any, of the
Company issued pursuant to the terms of the Securities Purchase Agreement. The
term "Closing Bid Price" means, for any security as of any date, the closing bid
price of such security on the principal securities exchange or trading market
where such security is listed or traded as reported by Bloomberg Financial
Markets or a comparable reporting service of national reputation selected by the
Company and reasonably acceptable to the holder hereof (the "Holder") if
Bloomberg Financial Markets is not then reporting closing bid prices of such
security (collectively, "Bloomberg"), or if the foregoing does not apply, the
last reported sale price of such security in the 


                                     EX-29
<PAGE>   3

over-the-counter market on the electronic bulletin board of such security as
reported by Bloomberg, or, if no sale price is reported for such security by
Bloomberg, the average of the bid prices of any market makers for such security
as reported in the "pink sheets" by the National Quotation Bureau, Inc. If the
Closing Bid Price cannot be calculated for such security on such date on any of
the foregoing bases, the Closing Bid Price of such security on such date shall
be the fair market value as reasonably determined by an investment banking firm
selected by the Company and reasonably acceptable to the Holder with the costs
of such appraisal to be borne by the Company. As used herein, "First Closing
Date means June 2, 1997.

        This Warrant is subject to the following terms, provisions, and
conditions:

        1. Mechanics of Exercise. Subject to the provisions hereof, including,
without limitation, the limitations contained in Section 7(f) hereof, this
Warrant may be exercised as follows:

          (a) Manner of Exercise. This Warrant may be exercised by the Holder,
in whole or in part, by the surrender of this Warrant (or evidence of loss,
theft, destruction or mutilation thereof in accordance with Section 7(c)
hereof), together with a completed exercise agreement in the form of Exercise
Agreement attached hereto as Exhibit 1 (the "Exercise Agreement"), to the
Company at the Company's principal executive offices (or such other office or
agency of the Company as it may designate by notice to the Holder), and a
written calculation of the number of shares of Common Stock to be issued upon
such exercise in accordance with the terms hereof (a "Cashless Exercise"). In
lieu of paying the Exercise Price in cash, the Holder shall surrender this
Warrant for the number of shares of Common Stock determined by multiplying the
number of Warrant Shares to which it would otherwise be entitled by a fraction,
the numerator of which shall be the difference between the then current Market
Price per share of the Common Stock and the Exercise Price, and the denominator
of which shall be the then current Market Price per share of Common Stock. The
Warrant Shares so purchased shall be deemed to be issued to the Holder or
Holder's designees, as the record owner of such shares, as of the date on which
this Warrant shall have been surrendered, the completed Exercise Agreement shall
have been delivered, and payment (or notice of an election to effect a Cashless
Exercise) shall have been made for such shares as set forth above.

        (b) Issuance of Certificates. Subject to Section 1(c), Certificates for
the Warrant Shares so purchased, representing the aggregate number of shares
specified in the Exercise Agreement, shall be delivered to the Holder within a
reasonable time, not exceeding three (3) business days, after this Warrant shall
have been so exercised (the "Delivery Period"). The certificates so delivered
shall be in such denominations as may be requested by the Holder and shall be
registered in the name of Holder or such other name as shall be designated by
Holder. If this Warrant shall have been exercised only in part, then, unless
this Warrant has expired, the Company shall, at its expense, at the time of
delivery of such certificates, deliver to the Holder a new Warrant representing
the number of shares with respect to which this Warrant shall not then have been
exercised.

        (c) Exercise Disputes. In the case of any dispute with respect to an
exercise, the Company shall promptly issue such number of shares of Common Stock
as are not disputed in accordance with this Section. If such dispute only
involves the calculation of the Exercise Price, the Company shall submit the
disputed calculations to an independent accounting firm of national 


                                     EX-30
<PAGE>   4

standing (selected by the Holder; provided that the Holder currently does not
have a client relationship with such accounting firm) via facsimile within two
(2) business days of receipt of the Exercise Agreement. The accountant shall
audit the calculations and notify the Company and the Converting Holder of the
results no later than two (2) business days from the date it receives the
disputed calculations. The accountant's calculation shall be deemed conclusive,
absent manifest error. The Company shall then issue the appropriate number of
shares of Common Stock in accordance with this Section.

        (d)    Fractional Shares. No fractional shares of Common Stock are to be
issued upon the exercise of this Warrant, but the Company shall pay a cash
adjustment in respect of any fractional share which would otherwise be issuable
in an amount equal to the same fraction of the Exercise Price of a share of
Common Stock (as determined for exercise of this Warrant into whole shares of
Common Stock).

        (e)    Buy-In. If (i) the Company fails for any reason to deliver during
the Delivery Period shares of Common Stock to a Holder upon an exercise of this
Warrant and (ii) after the applicable Delivery Period with respect to such an
exercise, a Holder purchases (in an open market transaction or otherwise) shares
of Common Stock to make delivery upon a sale by a Holder of the shares of Common
Stock (the "Sold Shares") which such Holder anticipated receiving upon such
exercise (a "Buy-In"), the Company shall pay such Holder (in addition to any
other remedies available to Holder) the amount by which (x) such Holder's total
purchase price (including brokerage commission, if any) for the shares of Common
Stock so purchased exceeds (y) the net proceeds received by the such Holder from
the sale of the Sold Shares. For example, if a Holder purchases shares of Common
Stock having a total purchase price of $11,000 to cover a Buy-In with respect to
shares of Common Stock sold for $10,000, the Company will be required to pay
such Holder $1,000. A Holder shall provide the Company written notification
indicating any amounts payable to Holder pursuant to this subsection.

        2.     Period of Exercise. This Warrant is exercisable at any time or 
from time to time on or after the date hereof and before Midnight, San Diego
time, June 2, 2002 (the "Exercise Period").

        3.     Certain Agreements of the Company. The Company hereby covenants 
and agrees as follows:

               (a)  Shares to be Fully Paid. All Warrant Shares will, upon
issuance in accordance with the terms of this Warrant, be validly issued, fully
paid, and nonassessable and free from all taxes, liens, claims and encumbrances.

               (b)  Reservation of Shares. During the Exercise Period, the
Company shall at all times have authorized, and reserved for the purpose of
issuance upon exercise of this Warrant, a sufficient number of shares of Common
Stock to provide for the exercise of this Warrant.

               (c)  Listing. Subject to the remainder of this Section 3(c), the
Company shall ensure that its shares of Common Stock (including all Warrant
Shares) are listed and available for trading on the OTC Bulletin Board. The
Company shall promptly following the First Closing use its best efforts to
satisfy the listing requirements of, and secure the listing of the Common Stock


                                     EX-31
<PAGE>   5

(including, without limitation, with respect to the Warrant Shares) upon, the
Nasdaq Small Cap Market ("NASDAQ"). Thereafter, the Company shall (i) use its
best efforts to continue the listing and trading of its Common Stock on the
NASDAQ, or on the Nasdaq National Market System ("NMS"), the New York Stock
Exchange ("NYSE") or the American Stock Exchange ("AMEX"); (ii) take all action
necessary to continue the listing and trading of its Common Stock on the OTC
Bulletin Board if the Common Stock is not listed and traded on NASDAQ, NMS, NYSE
or AMEX; and (iii) comply in all respects with the Company's reporting, filing
and other obligations under the by-laws or rules of the National Association of
Securities Dealers ("NASD") and such exchanges, as applicable.

               (d)  Certain Actions Prohibited. The Company will not, by
amendment of its charter or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed by it hereunder, but will at all times in
good faith assist in the carrying out of all the provisions of this Warrant and
in the taking of all such actions as may reasonably be requested by the Holder
of this Warrant in order to protect the exercise privilege of the Holder of this
Warrant against dilution or other impairment, consistent with the tenor and
purpose of this Warrant. Without limiting the generality of the foregoing, the
Company (i) will not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the Exercise Price then in
effect, and (ii) will take all such actions as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock upon the exercise of this Warrant.

               4.   Antidilution Provisions. During the Exercise Period, the
Exercise Price and the number of Warrant Shares shall be subject to adjustment
from time to time as provided in this Section 4. In the event that any
adjustment of the Exercise Price as required herein results in a fraction of a
cent, such Exercise Price shall be rounded up or down to the nearest cent.

               (a)  Adjustment of Exercise Price and Number of Shares upon
Issuance of Common Stock. Except as otherwise provided in Section 4(c) and 4(e)
hereof, if and whenever after the First Closing Date, the Company issues or
sells, or in accordance with Section 4(b) hereof is deemed to have issued or
sold, any shares of Common Stock for no consideration or for a consideration per
share less than the Market Price (as herein defined) on the date of issuance (a
"Dilutive Issuance"), then effective immediately upon the Dilutive Issuance, the
Exercise Price will be adjusted in accordance with the following formula:

               E' = E x O + P/M
                        -------
                         CSDO

               where:

               E'     =      the adjusted Exercise Price
               E      =      the then current Exercise Price;
               M      =      the then current Market Price;
               O      =      the number of shares of Common Stock  outstanding  
                             immediately prior to the Dilutive Issuance;


                                     EX-32
<PAGE>   6

               P      =      the aggregate consideration, calculated as set
                             forth in Section 4(b) hereof, received by the
                             Company upon such Dilutive Issuance; and
               CSDO   =      the total number of shares of Common Stock Deemed
                             Outstanding (as herein defined) immediately after
                             the Dilutive Issuance.

               (b)  Effect on Exercise Price of Certain Events. For purposes of
determining the adjusted Exercise Price under Section 4(a) hereof, the following
will be applicable:

                    (i)       Issuance of Rights or Options. If the Company in 
any manner issues or grants any warrants, rights or options, whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities exercisable, convertible into or exchangeable for Common Stock
("Convertible Securities") (such warrants, rights and options to purchase Common
Stock or Convertible Securities are hereinafter referred to as "Options") and
the price per share for which Common Stock is issuable upon the exercise of such
Options is less than the Market Price on the date of issuance ("Below Market
Options"), then the maximum total number of shares of Common Stock issuable upon
the exercise of all such Below Market Options (assuming full exercise,
conversion or exchange of Convertible Securities, if applicable) will, as of the
date of the issuance or grant of such Below Market Options, be deemed to be
outstanding and to have been issued and sold by the Company for such price per
share. For purposes of the preceding sentence, the price per share for which
Common Stock is issuable upon the exercise of such Below Market Options is
determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the issuance or granting of such Below Market
Options, plus the minimum aggregate amount of additional consideration, if any,
payable to the Company upon the exercise of all such Below Market Options, plus,
in the case of Convertible Securities issuable upon the exercise of such Below
Market Options, the minimum aggregate amount of additional consideration payable
upon the exercise, conversion or exchange thereof at the time such Convertible
Securities first become exercisable, convertible or exchangeable, by (ii) the
maximum total number of shares of Common Stock issuable upon the exercise of all
such Below Market Options (assuming full conversion of Convertible Securities,
if applicable). No further adjustment to the Exercise Price will be made upon
the actual issuance of such Common Stock upon the exercise of such Below Market
Options or upon the exercise, conversion or exchange of Convertible Securities
issuable upon exercise of such Below Market Options.

                    (ii)      Issuance of Convertible Securities.

                              (A) If the Company in any manner issues or sells
any Convertible Securities, whether or not immediately convertible (other than
where the same are issuable upon the exercise of Options) and the price per
share for which Common Stock is issuable upon such exercise, conversion or
exchange (as determined pursuant to Section 4(b)(ii)(B) if applicable) is less
than the Market Price on the date of issuance, then the maximum total number of
shares of Common Stock issuable upon the exercise, conversion or exchange of all
such Convertible Securities will, as of the date of the issuance of such
Convertible Securities, be deemed to be outstanding and to have been issued and
sold by the Company for such price per share. For the purposes of the preceding
sentence, the price per share for which Common Stock is issuable upon such
exercise, conversion or exchange is determined by dividing (i) the total amount,
if any, received or receivable by the Company as consideration for the issuance
or sale of all such Convertible Securities, plus the 


                                     EX-33
<PAGE>   7

minimum aggregate amount of additional consideration, if any, payable to the
Company upon the exercise, conversion or exchange thereof at the time such
Convertible Securities first become exercisable, convertible or exchangeable, by
(ii) the maximum total number of shares of Common Stock issuable upon the
exercise, conversion or exchange of all such Convertible Securities. No further
adjustment to the Exercise Price will be made upon the actual issuances of such
Common Stock upon exercise, conversion or exchange of such Convertible
Securities.

                              (B)  If the Company in any manner issues or sells
any Convertible Securities with a fluctuating conversion or exercise price or
exchange ratio (a "Variable Rate Convertible Security"), then the price per
share for which Common Stock is issuable upon such exercise, conversion or
exchange for purposes of the calculation contemplated by Section 4(b)(ii)(A)
shall be deemed to be the lowest price per share which would be applicable
assuming that (1) all holding period and other conditions to any discounts
contained in such Convertible Security have been satisfied, and (2) the Market
Price on the date of issuance of such Convertible Security was 75% of the Market
Price on such date (the "Assumed Variable Market Price"). In addition, the
Exercise Price shall be adjusted any time or times the Market Price thereafter
is less than or equal to the Assumed Variable Market Price last used for making
any adjustment under this Section 4 with respect to any Variable Rate
Convertible Security. At such time, the Exercise Price shall be adjusted to the
Exercise Price which would have resulted if the Assumed Variable Market Price at
the time of issuance of the Variable Rate Convertible Security had been 75% of
the Market Price existing at the time of the adjustment required by this
sentence.

                    (iii)     Change in Option Price or Conversion Rate. If 
there is a change at any time in (i) the amount of additional consideration
payable to the Company upon the exercise of any Options; (ii) the amount of
additional consideration, if any, payable to the Company upon the exercise,
conversion or exchange or any Convertible Securities; or (iii) the rate at which
any Convertible Securities are convertible into or exchangeable for Common Stock
(other than under or by reason of provisions designed to protect against
dilution), the Exercise Price in effect at the time of such change will be
readjusted to the Exercise Price which would have been in effect at such time
had such Options or Convertible Securities still outstanding provided for such
changed additional consideration or changed conversion rate, as the case may be,
at the time initially granted, issued or sold.

                    (iv)      Treatment of Expired Options and Unexercised
Convertible Securities. If, in any case, the total number of shares of Common
Stock issuable upon exercise of any Options or upon exercise, conversion or
exchange of any Convertible Securities is not, in fact, issued and the rights to
exercise such option or to exercise, convert or exchange such Convertible
Securities shall have expired or terminated, the Exercise Price then in effect
will be readjusted to the Exercise Price which would have been in effect at the
time of such expiration or termination had such Options or Convertible
Securities, to the extent outstanding immediately prior to such expiration or
termination (other than in respect of the actual number of shares of Common
Stock issued upon exercise or conversion thereof), never been issued.

                    (v)  Calculation of Consideration Received. If any Common
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Warrant will be the
amount received by the Company therefor, before 


                                     EX-34
<PAGE>   8

deduction of reasonable commissions, underwriting discounts or allowances or
other reasonable expenses paid or incurred by the Company in connection with
such issuance, grant or sale. In case any Common Stock, Options or Convertible
Securities are issued or sold for a consideration part or all of which shall be
other than cash, the amount of the consideration other than cash received by the
Company will be the fair market value of such consideration except where such
consideration consists of securities, in which case the amount of consideration
received by the Company will be the Market Price thereof as of the date of
receipt. In case any Common Stock, Options or Convertible Securities are issued
in connection with any merger or consolidation in which the Company is the
surviving corporation, the amount of consideration therefor will be deemed to be
the fair market value of such portion of the net assets and business of the
non-surviving corporation as is attributable to such Common Stock, Options or
Convertible Securities, as the case may be. The fair market value of any
consideration other than cash or securities will be determined in good faith by
an investment banker or other appropriate expert of national reputation selected
by the Company and reasonably acceptable to the Holder, with the costs of such
appraisal to be borne by the Company.

                    (vi)      Exceptions to Adjustment of Exercise Price. No
adjustment to the Exercise Price will be made (i) upon the exercise of any
warrants, options or convertible securities issued and outstanding on the First
Closing Date in accordance with the terms of such securities as of such date;
(ii) upon the grant or exercise of any stock or options which may hereafter be
granted or exercised under any employee benefit plan of the Company now existing
or to be implemented in the future, so long as the issuance of such stock or
options is approved by a majority of the non-employee members of the Board of
Directors of the Company or a majority of the members of a committee of
non-employee directors established for such purpose; (iii) upon the issuance of
the convertible term debentures of the Company (the "Debentures"), the preferred
stock, par value $.00001 per share, of the Company (the "Preferred Stock") or
Warrants in accordance with terms of the Securities Purchase Agreement; (iv)
upon the exercise of the Warrants or conversion of the Debentures or Preferred
Stock or (v) the warrants to purchase Common Stock issued or to be issued to
Swartz Investments, LLC in consideration of its services in connection with the
Securities Purchase Agreement and the transactions contemplated thereby so long
as such warrants are not exercisable, in the aggregate, for more than 330,000
shares of Common Stock.

               (c)  Subdivision or Combination of Common Stock. If the Company,
at any time after the First Closing Date, subdivides (by any stock split, stock
dividend, recapitalization, reorganization, reclassification or otherwise) its
shares of Common Stock into a greater number of shares, then, after the date of
record for effecting such subdivision, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced. If the Company, at
any time after the initial issuance of this Warrant, combines (by reverse stock
split, recapitalization, reorganization, reclassification or otherwise) its
shares of Common Stock into a smaller number of shares, then, after the date of
record for effecting such combination, the Exercise Price in effect immediately
prior to such combination will be proportionately increased.

               (d)  Adjustment in Number of Shares. Upon each adjustment of the
Exercise Price pursuant to the provisions of this Section 4, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be adjusted
by multiplying a number equal to the Exercise Price in effect immediately prior
to such adjustment by the number of shares of Common Stock issuable 


                                     EX-35
<PAGE>   9

upon exercise of this Warrant immediately prior to such adjustment and dividing
the product so obtained by the adjusted Exercise Price.

               (e)  Major Transactions. If the Company shall consolidate with or
merge into any corporation or reclassify its outstanding shares of Common Stock
(other than by way of subdivision or reduction of such shares) (each a "Major
Transaction"), then each holder of a Warrant shall thereafter be entitled to
receive consideration, in exchange for such Warrant, equal to the greater of, as
determined in the sole discretion of such holder: (i) a warrant to purchase, at
the same aggregate exercise price, the number of shares of stock or securities
or property of the Company, or of the entity resulting from such consolidation
or merger (the "Major Transaction Consideration"), to which a holder of the
number of shares of Common Stock delivered upon exercise of such Warrant would
have been entitled upon such Major Transaction had the holder of such Warrant
exercised the Warrant on the trading date immediately preceding the public
announcement of the transaction resulting in such Major Transaction and had such
Common Stock been issued and outstanding and had such holder been the holder of
record of such Common Stock at the time of such Major Transaction, and the
Company shall make lawful provision therefor as a part of such consolidation,
merger or reclassification; and (ii) cash paid by the Company in immediately
available funds, in an amount equal to the Black-Scholes Amount (as defined
herein) times the number of shares of Common Stock for which this Warrant was
exercisable on the date immediately preceding the date of such Major
Transaction. No sooner than ten (10) days nor later than five (5) days prior to
the consummation of the Major Transaction, but not prior to the public
announcement of such Major Transaction, the Company shall deliver written notice
("Notice of Major Transaction") to each holder of Warrants, which Notice of
Major Transaction shall be deemed to have been delivered one (1) business day
following the Company's sending such notice by telecopy (provided that the
Company sends a confirming copy of such notice on the same day by overnight
courier) of such Notice of Major Transaction. Such Notice of Major Transaction
shall indicate the amount and type of the Major Transaction Consideration which
such holder would receive under clause (i) of this paragraph (e). If the Major
Transaction Consideration does not consist entirely of United States currency,
such holder may elect to receive United States currency in an amount equal to
the value of the Major Transaction Consideration in lieu of the Major
Transaction Consideration by delivering notice of such election to the Company
within five (5) days of the holder's receipt of the Notice of Major Transaction.

        The "Black-Scholes Amount" shall be an amount determined by calculating
the "Black-Scholes" value of an option to purchase one share of Common Stock on
the applicable page on the Bloomberg online page, using the following variable
values: (i) the current market price of the Common Stock equal to the closing
trade price on the last trading day before the date of the Notice of the Major
Transaction; (ii) volatility of the Common Stock equal to the volatility of the
Common Stock during the 100 trading day period preceding the date of the Notice
of the Major Transaction; (iii) a risk free rate equal to the interest rate on
the United States treasury bill or treasury note with a maturity corresponding
to the remaining term of this Warrant on the date of the Notice of the Major
Transaction; and (iv) an exercise price equal to the Exercise Price on the date
of the Notice of the Major Transaction. In the event such calculation function
is no longer available utilizing the Bloomberg online page, the Holder shall
calculate such amount in its sole discretion using the closest available
alternative mechanism and variable values to those available utilizing the
Bloomberg online page for such calculation function.


                                     EX-36
<PAGE>   10

               (f)  Distribution of Assets. The Company shall provide Holder 
with at least thirty (30) trading days written notice prior to any date on which
the Company intends to declare or make any distribution of its assets (or rights
to acquire its assets) to holders of Common Stock as a partial liquidating
dividend, by way of return of capital or otherwise (including any dividend or
distribution to the Company's shareholders of cash or shares (or rights to
acquire shares) of capital stock of a subsidiary).

               (g)  Notices of Adjustment. Upon the occurrence of any event 
which requires any adjustment of the Exercise Price, then, and in each such
case, the Company shall give notice thereof to the Holder, which notice shall
state the Exercise Price resulting from such adjustment and the increase or
decrease in the number of Warrant Shares purchasable at such price upon
exercise, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based. Such calculation shall be certified
by the chief financial officer of the Company.

               (h)  Minimum Adjustment of Exercise Price. No adjustment of the
Exercise Price shall be made in an amount of less than 1% of the Exercise Price
in effect at the time such adjustment is otherwise required to be made, but any
such lesser adjustment shall be carried forward and shall be made at the time
and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

               (i)  No Fractional Shares. No fractional shares of Common Stock
are to be issued upon the exercise of this Warrant, but the Company shall pay a
cash adjustment in respect of any fractional share which would otherwise be
issuable in an amount equal to the same fraction of the Market Price of a share
of Common Stock on the date of such exercise.

               (j)  Other Notices. In case at any time:

                    (i)  the Company shall declare any dividend upon the Common
Stock payable in shares of stock of any class or make any other distribution to
the holders of the Common Stock;

                    (ii) the Company shall offer for subscription pro rata to
the holders of the Common Stock any additional shares of stock of any class or
other rights;

                    (iii) there shall be any capital reorganization of the
Company, or reclassification of the Common Stock, or consolidation or merger of
the Company with or into, or sale of all or substantially all of its assets to,
another corporation or entity; or

                    (iv) there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the Holder (a) notice of the
date on which the books of the Company shall close or a record shall be taken
for determining the holders of Common Stock entitled to receive any such
dividend, distribution, or subscription rights or for determining

the holders of Common Stock entitled to vote in respect of any such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding-up and (b) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, notice of the date (or, if not then known, a reasonable
approximation thereof by the Company) when the same shall take place. Such
notice shall also specify the date on which the holders of Common Stock shall be
entitled to receive such dividend, distribution, or subscription rights or to
exchange their Common Stock for stock or other securities or property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation, or winding-up, as the case may be. Such notice
shall be given at least 30 days prior to the record date or the date on which
the Company's books are closed in respect thereto. Failure to give any such
notice or any defect therein shall not affect the validity of the proceedings
referred to in clauses (i), (ii), (iii) and (iv) above.

               (k)  Certain Events. If, at any time after the First Closing 
Date, any event occurs of the type contemplated by the adjustment provisions of
this Section 4 but not expressly provided for by such provisions, the Company
will give notice of such event as provided in Section 4(g) hereof, and the
Company's board of directors will make an appropriate adjustment in the Exercise
Price and the number of shares of Common Stock acquirable upon exercise of this
Warrant so that the rights of the Holder shall be neither enhanced nor
diminished by such event.

               (l)  Certain Definitions.

                    (i) "Common Stock Deemed Outstanding" shall mean the number
of shares of Common Stock actually outstanding (not including shares of Common
Stock held in the treasury of the Company), plus (x) in case of any adjustment
required by Section 4(a) resulting from the issuance of any Options, the maximum
total number of shares of Common Stock issuable upon the exercise of the Options
for which the adjustment is required (including any Common Stock issuable upon
the conversion of Convertible Securities issuable upon the exercise of such
Options), and (y) in the case of any adjustment required by Section 4(a)
resulting from the issuance of any Convertible Securities, the maximum total
number of shares of Common Stock issuable upon the exercise, conversion or
exchange of the Convertible Securities for which the adjustment is required, as
of the date of issuance of such Convertible Securities, if any.

                    (ii) "Market Price," as of any date, means the average of
the Closing Bid Prices for the shares of Common Stock for the five (5)
consecutive trading days ending on the trading day immediately preceding such
date.

                    (iii) "Common Stock," for purposes of this Section 4,
includes the Common Stock and any additional class of stock of the Company
having no preference as to dividends or distributions on liquidation, provided
that the shares purchasable pursuant to this Warrant shall include only Common
Stock in respect of which this Warrant is exercisable, or shares resulting from
any subdivision or combination of such Common Stock, or in the case of any
reorganization, reclassification, consolidation, merger, or sale of the
character referred to in Section 4(e) hereof, the stock or other securities or
property provided for in such Section.

        5. Issue Tax. The issuance of certificates for Warrant Shares upon the
exercise of this Warrant shall be made without charge to the Holder or such
shares for any issuance tax or other 


                                     EX-38
<PAGE>   12

costs in respect thereof, provided that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any certificate in a name other than the Holder.

        6.     No Rights or Liabilities as a Shareholder. This Warrant shall not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company. No provision of this Warrant, in the absence of affirmative action by
the Holder to purchase Warrant Shares, and no mere enumeration herein of the
rights or privileges of the Holder, shall give rise to any liability of the
Holder for the Exercise Price or as a shareholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.

        7.     Transfer, Exchange, Redemption and Replacement of Warrant.

               a.   Restriction on Transfer. This Warrant and the rights granted
to the Holder are transferable, in whole or in part, upon surrender of this
Warrant, together with a properly executed assignment in the form attached
hereto as Exhibit 2, at the office or agency of the Company referred to in
Section 7(e) below, provided, however, that any transfer or assignment shall be
subject to the to the provisions of Section 5.1 and 5.2 of the Securities
Purchase Agreement. Until due presentment for registration of transfer on the
books of the Company, the Company may treat the registered holder hereof as the
owner and holder hereof for all purposes, and the Company shall not be affected
by any notice to the contrary. Notwithstanding anything to the contrary
contained herein, the registration rights described in Section 8 hereof are
assignable only in accordance with the provisions of that certain Registration
Rights Agreement, dated as of June 2, 1997, by and among the Company and the
other signatories thereto (the "Registration Rights Agreement").

               b.   Warrant Exchangeable for Different Denominations. This 
Warrant is exchangeable, upon the surrender hereof by the Holder at the office
or agency of the Company referred to in Section 7(e) below, for new Warrants, in
the form hereof, of like tenor of different denominations representing in the
aggregate the right to purchase the number of shares of Common Stock which may
be purchased hereunder, each of such new Warrants to represent the right to
purchase such number of shares as shall be designated by the Holder of at the
time of such surrender.

               c.   Replacement of Warrant. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant or, in the case of any such loss, theft, or destruction, upon
delivery, of an indemnity agreement reasonably satisfactory in form and amount
to the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, new Warrants, in the form hereof, in such
denominations as Holder may request. The Company shall not be obligated to
reissue such Warrant if Holder contemporaneously requests the Company to convert
this Warrant.

               d.   Cancellation; Payment of Expenses. Upon the surrender of 
this Warrant in connection with any transfer, exchange, or replacement as
provided in this Section 7, this Warrant shall be promptly canceled by the
Company. The Company shall pay all taxes (other than securities 


                                     EX-39
<PAGE>   13

transfer taxes) and charges payable in connection with the preparation,
execution, and delivery of Warrants pursuant to this Section 7.

               e.   Warrant Register. The Company shall maintain, at its 
principal executive offices (or such other office or agency of the Company as it
may designate by notice to the Holder), a register for this Warrant, in which
the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

               f.   Additional Restriction on Exercise or Transfer.
Notwithstanding anything to the contrary contained herein, the Warrants shall
not be exercisable by the Holder to the extent (but only to the extent) that, if
exercisable by Holder, Holder would beneficially own in excess of 4.9% of the
shares of Common Stock. To the extent the above limitation applies, the
determination of whether the Warrants shall be exercisable (vis-a-vis other
securities owned by Holder) and of which Warrants shall be convertible shall be
in the sole discretion of the Holder and submission of the Warrants for exercise
shall be deemed to be the Holder's determination of whether such Warrants are
exercisable and of which Warrants are exercisable, subject to such aggregate
percentage limitation. No prior inability to exercise Warrants pursuant to this
paragraph shall have any effect on the applicability of the provisions of this
paragraph with respect to any subsequent determination of exercisability. For
the purposes of this paragraph, beneficial ownership and all calculations,
including without limitation, with respect to calculations of percentage
ownership shall be determined in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as amended, and Regulation 13D and G thereunder. The
provisions of this paragraph may be waived and/or implemented in a manner
otherwise than strictly in conformity with the foregoing provisions of this
paragraph f with the approval of the Board of Directors of the Corporation and
the holders of majority in interest in the then outstanding Debentures and
Warrants (voting together as a single class): (i) with respect to any matter to
cure any ambiguity herein, to correct this paragraph (or any portion hereof)
which may be defective or inconsistent with the intended 4.9% beneficial
ownership limitation herein contained or to make changes or supplements
necessary or desirable to properly give effect to such 4.9% limitation; and (ii)
with respect to any other matter, with the further consent of the holders of a
majority of the then outstanding shares of Common Stock. The limitations
contained in this paragraph shall apply to a successor holder of Warrants if,
and to the extent, elected by such successor holder concurrently with its
acquisition of such Warrants, such election to be promptly confirmed in writing
to the Company (provided no transfer or series of transfer to a successor holder
or holders shall be used by a Holder to evade the limitations contained in this
paragraph).

        8.     Registration Rights. The initial holder of this Warrant (and 
certain assignees thereof) is entitled to the benefit of such registration
rights in respect of the Warrant Shares as are set forth in the Registration
Rights Agreement.

        9.     Notices. Any notice herein required or permitted to be given 
shall be in writing and may be personally served or delivered by courier or by
confirmed telecopy, and shall be deemed delivered at the time and date of
receipt (which shall include telephone line facsimile transmission). The
addresses for such communications shall be:

                                       OF
                         PATRIOT SCIENTIFIC CORPORATION

        THIS CERTIFIES that Swartz Family Partnership, L.P. or any subsequent
("Holder") hereof, has the right to purchase from PATRIOT SCIENTIFIC
CORPORATION, a Delaware corporation (the "Company"), not more than 38,250 fully
paid and nonassessable shares of the Company's Common Stock, par value $.00001

Section 3 below, subject to adjustment as provided herein, at any time on or
before 5:00 p.m., San Diego, California time, on May 31, 2002.

        The Holder of this Warrant agrees with the Company that this Warrant is
issued and all rights hereunder shall be held subject to all of the conditions,
limitations and provisions set forth herein.

        1.     Date of Issuance.

        This Warrant shall be deemed to be issued on November 24, 1997 ("Date of
Issuance").

        2.     Exercise.

        (a) Manner of Exercise. This Warrant may be exercised as to all or any
lesser number of full shares of Common Stock covered hereby upon surrender of
this Warrant, with the Exercise Form attached hereto duly executed, together
with the full Exercise Price (as defined in Section 3) for each share of Common
Stock as to which this Warrant is exercised, at the office of the Company,
Patriot Scientific Corporation, 10989 Via Frontera, San Diego, California 92127,

("Exercise Form") by facsimile (such surrender and payment of the Exercise Price
hereinafter called the "Exercise of this Warrant").

        (b) Date of Exercise. The "Date of Exercise" of the Warrant shall be

days thereafter. The original Warrant and Exercise Form must be received within
five (5) business days of the Date of Exercise, or the exercise may, at the

identical to this Warrant) representing any unexercised portion of this Warrant
in addition to such Common Stock.

        (d) Holder of Record. Each person in whose name any Warrant for shares
of Common Stock is issued shall, for all purposes, be deemed to have become the
Holder of record of such shares on the Date of Exercise of this Warrant,
irrespective of the date of delivery of such shares of Common Stock. Nothing in
this Warrant shall be construed as conferring upon the Holder hereof any rights
as a shareholder of the Company.

        3.     Payment of Warrant Exercise Price.

        The Exercise Price ("Exercise Price") shall equal $1.50.

        For purposes hereof, the term "Closing Price" shall mean the closing
price on the National Association of Securities Dealers Automated Quotation
System ("Nasdaq") Small Cap Market or OTC Bulletin Board, or if no longer traded
on the Nasdaq Small Cap Market or OTC Bulletin Board, the closing price on the
principal national securities exchange or the National Market System on which
the Common Stock is so traded and, if not available, the mean of the high and
low prices on the principal national securities exchange or the National
Securities Exchange on which the Common Stock is so traded.

        Payment of the Exercise Price may be made by either of the following, or
a combination thereof, at the election of Holder:

        (i)    Cash Exercise:  cash, certified check or cashiers check or wire 
transfer; or

        (ii)   Cashless Exercise: surrender of this Warrant at the principal
office of the Company together with notice of cashless election, in which event
the Company shall issue Holder a number of shares of Common Stock computed using
the following formula:

                      X = Y (A-B)/A

where:  X = the number of shares of Common Stock to be issued to Holder.

        Y = the number of shares of Common Stock for which this Warrant
            is being exercised.


                                     EX-48
<PAGE>   4

               A = the Market Price of one (1) share of Common Stock (for
               purposes of this Section 3(ii), the "Market Price" shall be
               defined as the average closing price of the Common Stock for the
               five (5) trading days prior to the Date of Exercise of this
               Warrant (the "Average Closing Price"), as reported by Nasdaq or
               if the Common Stock is not traded on Nasdaq, the Average Closing
               Price in the over-the-counter market; provided, however, that if
               the Common Stock is listed on a stock exchange, the Market Price
               shall be the Average Closing Price on such exchange. If the
               Common Stock is/was not traded during the five (5) trading days
               prior to the Date of Exercise, then the closing price for the
               last publicly traded day shall be deemed to be the closing price
               for any and all (if applicable) days during such five (5) trading
               day period.

               B = the Exercise Price.

For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is intended,
understood and acknowledged that the Common Stock issuable upon exercise of this
Warrant in a cashless exercise transaction shall be deemed to have been acquired
at the time this Warrant was issued. Moreover, it is intended, understood and
acknowledged that the holding period for the Common Stock issuable upon exercise
of this Warrant in a cashless exercise transaction shall be deemed to have
commenced on the date this Warrant was issued.

        4.     Transfer and Registration.

        (a) Transfer Rights. Subject to the provisions of Section 8 of this
Warrant, this Warrant may be transferred on the books of the Company, in whole
or in part, in person or by attorney, upon surrender of this Warrant properly
endorsed. This Warrant shall be canceled upon such surrender and, as soon as
practicable thereafter, the person to whom such transfer is made shall be
entitled to receive a new Warrant or Warrants as to the portion of this Warrant
transferred, and the Holder of this Warrant shall be entitled to receive a new
Warrant or Warrants as to the portion hereof retained.

        (b) Registrable Securities. The Common Stock issuable upon the exercise
of this Warrant constitute "Registrable Securities" under that certain
Registration Rights Agreement dated on or about May 30, 1997 by and between the
Company and Swartz Investments, LLC and, accordingly, has the benefit of the
registration rights pursuant to that agreement.

        5.     Anti-Dilution Adjustments.

        (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common Stock, then the Holder hereof, upon Exercise of this
Warrant after the record date for the determination of Holders of Common Stock
entitled to receive such dividend, shall be entitled to receive upon Exercise of
this Warrant, in addition to the number of shares of Common Stock as to which
this Warrant is Exercised, such additional shares of Common Stock as such Holder
would have received had this Warrant been Exercised immediately prior to such
record date and the Exercise Price will be proportionately adjusted.


                                     EX-49
<PAGE>   5

        (b) Recapitalization or Reclassification. If the Company shall at any
time effect a recapitalization, reclassification or other similar transaction of
such character that the shares of Common Stock shall be changed into or become
exchangeable for a larger or smaller number of shares, then upon the effective
date thereof, the number of shares of Common Stock which the Holder hereof shall
be entitled to purchase upon Exercise of this Warrant shall be increased or
decreased, as the case may be, in direct proportion to the increase or decrease
in the number of shares of Common Stock by reason of such recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the
case of an increase in the number of shares, proportionally decreased and, in
the case of decrease in the number of shares, proportionally increased. The
Company shall give the Warrant Holder the same notice it provides to holders of
Common Stock of any transaction described in this Section 5(b).

        (c) Distributions. If the Company shall at any time distribute to
Holders of Common Stock cash, evidences of indebtedness or other securities or
assets (other than cash dividends or distributions payable out of earned surplus
or net profits for the current or preceding year) then, in any such case, the
Holder of this Warrant shall be entitled to receive, upon exercise of this
Warrant, with respect to each share of Common Stock issuable upon such Exercise,
the amount of cash or evidences of indebtedness or other securities or assets
which such Holder would have been entitled to receive with respect to each such
share of Common Stock as a result of the happening of such event had this
Warrant been Exercised immediately prior to the record date or other date fixing
shareholders to be affected by such event (the "Determination Date") or, in lieu
thereof, if the Board of Directors of the Company should so determine at the
time of such distribution, a reduced Exercise Price determined by multiplying
the Exercise Price on the Determination Date by a fraction, the numerator of
which is the result of such Exercise Price reduced by the value of such
distribution applicable to one share of Common Stock (such value to be
determined by the Board in its discretion) and the denominator of which is such
Exercise Price.

        (d) Notice of Consolidation or Merger. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock of the Company shall
be changed into the same or a different number of shares of the same or another
class or classes of stock or securities or other assets of the Company or
another entity or there is a sale of all or substantially all the Company's
assets (a "Corporate Change"), then this Warrant shall be assumed by the
acquiring entity or any affiliate thereof and thereafter this Warrant shall be
exerciseable into such class and type of securities or other assets as the
Holder would have received had the Holder exercised this Warrant immediately
prior to such Corporate Change; provided, however, that Company may not affect
any Corporate Change unless it first shall have given thirty (30) business days
notice to the Holder hereof of any Corporate Change.

        (e) Exercise Price Adjusted. As used in this Warrant, the term "Exercise
Price" shall mean the purchase price per share specified in Section 3 of this
Warrant, as it may be adjusted from time to time, until the occurrence of an
event stated in subsection (a), (b) or (c) of this Section 5 and thereafter
shall mean said price as adjusted from time to time in accordance with the
provisions of said subsection. No such adjustment under this Section 5 shall be
made unless such adjustment would change the Exercise Price at the time by $.01
or more; provided, however, that all adjustments not so made shall be deferred
and made when the aggregate thereof would change the Exercise Price at the time
by $.01 or more. No adjustment made pursuant to any provision of this Section 5
shall have the 


                                     EX-50
<PAGE>   6

effect of increasing the total consideration payable upon Exercise of this
Warrant in respect of all the Common Stock as to which this Warrant may be
exercised. Notwithstanding anything to the contrary contained herein, the
Exercise Price shall not be reduced to an amount below the par value of the
Common Stock.

        (f) Adjustments: Additional Shares, Securities or Assets. In the event
that at any time, as a result of an adjustment made pursuant to this Section 5,
the Holder of this Warrant shall, upon Exercise of this Warrant, become entitled
to receive shares and/or other securities or assets (other than Common Stock)
then, wherever appropriate, all references herein to shares of Common Stock
shall be deemed to refer to and include such shares and/or other securities or
assets; and thereafter the number of such shares and/or other securities or
assets shall be subject to adjustment from time to time in a manner and upon
terms as nearly equivalent as practicable to the provisions of this Section 5.

<PAGE>   7

        6.     Fractional Interests.

               No fractional shares or scrip representing fractional shares
shall be issuable upon the Exercise of this Warrant, but on Exercise of this
Warrant, the Holder hereof may purchase only a whole number of shares of Common
Stock. If, on Exercise of this Warrant, the Holder hereof would be entitled to a
fractional share of Common Stock or a right to acquire a fractional share of
Common Stock, such fractional share shall be disregarded and the number of
shares of Common Stock issuable upon conversion shall be the next higher number
of shares.

        7.     Reservation of Shares.

               The Company shall at all times reserve for issuance such number
of authorized and unissued shares of Common Stock (or other securities
substituted therefor as herein above provided) as shall be sufficient for
Exercise and payment of the Exercise Price of this Warrant. The Company
covenants and agrees that upon Exercise of this Warrant, all shares of Common
Stock issuable upon such Exercise shall be duly and validly issued, fully paid,
nonassessable and not subject to preemptive rights, rights of first refusal or
similar rights of any person or entity.

        8.     Restrictions on Transfer.

               (a) Registration or Exemption Required. This Warrant and the
Common Stock issuable on Exercise hereof have not been registered under the
Securities Act of 1933, as amended, and may not be sold, transferred, pledged,
hypothecated or otherwise disposed of in the absence of registration or the
availability of an exemption from registration under said Act. All shares of
Common Stock issued upon Exercise of this Warrant shall bear an appropriate
legend to such effect, if applicable.

               (b) Assignment. Assuming the conditions of (a) above regarding
registration or exemption have been satisfied, the Holder may sell, transfer,
assign, pledge or otherwise dispose of this Warrant, in whole or in part. Holder
shall deliver a written notice to Company, substantially in the form of the
Assignment attached hereto as Exhibit B, indicating the person or persons to
whom the Warrant shall be assigned and the respective number of warrants to be
assigned to each assignee. The Company shall effect the assignment within ten
days, and shall deliver to the assignee(s) designated by Holder a Warrant or
Warrants of like tenor and terms for the appropriate number of shares.

               (c) Investment Intent. The Warrant and Common Stock issuable upon
conversion are intended to be held for investment purposes and not with an
intent to distribution, as defined in the Act.

        9. Benefits of this Warrant.

               Nothing in this Warrant shall be construed to confer upon any
person other than the Company and the Holder of this Warrant any legal or
equitable right, remedy or claim under this Warrant and this Warrant shall be
for the sole and exclusive benefit of the Company and the Holder of this
Warrant.

               Upon receipt by the Company of evidence of the loss, theft,
destruction or mutilation of this Warrant, and (in the case of loss, theft or
destruction) of indemnity or security reasonably satisfactory to the Company,
and upon surrender and cancellation of this Warrant, if mutilated, the Company

                                       OF
                         PATRIOT SCIENTIFIC CORPORATION

        THIS CERTIFIES that THE INVESTOR COMMUNICATIONS GROUP, INC. or any
subsequent ("Holder") hereof, has the right to purchase from PATRIOT SCIENTIFIC

paid and nonassessable shares of the Company's Common Stock, par value $.00001
per share ("Common Stock"), at a price equal to the Exercise Price as defined in
Section 3 below, subject to adjustment as provided herein, at any time on or
before 5:00 p.m., San Diego, California time, on June 15, 1999, unless earlier
canceled pursuant to Section 2 (c) below.


        The Holder of this Warrant agrees with the Company that this Warrant is
issued and all rights hereunder shall be held subject to all of the conditions,
limitations and provisions set forth herein.

        1.     Date of Issuance.

        This Warrant shall be deemed to be issued on June 16, 1997 ("Date of

hereinafter called the "Exercise of this Warrant").

<PAGE>   3

        (b) Date of Exercise. The "Date of Exercise" of the Warrant shall be
defined as the date that the advance copy of the Exercise Form is sent by
facsimile to the Company, provided that the original Warrant and Exercise Form
are received by the Company within five (5) business days thereafter. The
original Warrant and Exercise Form must be received within five (5) business
days of the Date of Exercise, or the exercise may, at the Company's option, be
considered void. Alternatively, the Date of Exercise shall be defined as the
date the original Exercise Form is received by the Company, if Holder has not
sent advance notice by facsimile.

        (c) Cancellation of Warrant. This Warrant shall be canceled (i) upon its
Exercise, and, as soon as practical after the Date of Exercise, the Holder
hereof shall be entitled to receive Common Stock for the number of shares
purchased upon such Exercise, and if this Warrant is not exercised in full, the
Holder shall be entitled to receive a new Warrant or Warrants (containing terms
identical to this Warrant) representing any unexercised portion of this Warrant
in addition to such Common Stock, (ii) the earlier of (a) one year from the date

Marketing Agreement by and among the Company and the Holder dated June 16, 1997
if the Marketing Agreement shall have been terminated by the Holder.

        (d) Holder of Record. Each person in whose name any Warrant for shares
of Common Stock is issued shall, for all purposes, be deemed to have become the
Holder of record of such shares on the Date of Exercise of this Warrant,
irrespective of the date of delivery of such shares of Common Stock. Nothing in
this Warrant shall be construed as conferring upon the Holder hereof any rights
as a shareholder of the Company.

        3.     Payment of Warrant Exercise Price.

        The Exercise Price ("Exercise Price") shall equal $ 2.50.

        Payment of the Exercise Price may be made by cash, certified or cashiers
check, or wire transfer.

        For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is
intended, understood and acknowledged that the Common Stock issuable upon
exercise of this Warrant shall be deemed to have been acquired at the time this
Warrant was exercised. Moreover, it is intended, understood and acknowledged
that the holding period for the Common Stock issuable upon exercise of this
Warrant shall be deemed to have commenced on the date this Warrant was
exercised.


        4.     Transfer Rights and Piggyback Registration Rights.

        (a) Transfer Rights. Subject to the provisions of Section 8 of this
Warrant, this Warrant may be transferred on the books of the Company, in whole
or in part, in person or by attorney, upon surrender of this Warrant properly
endorsed. This Warrant shall be canceled upon such surrender and, as soon as
practicable thereafter, the person to whom such transfer is made shall be
entitled to receive a 


                                     EX-59
<PAGE>   4

new Warrant or Warrants as to the portion of this Warrant transferred, and the
Holder of this Warrant shall be entitled to receive a new Warrant or Warrants as
to the portion hereof retained.

        (b)    Piggyback Registration Rights. If at any time or from time to 
time subsequent to the exercise of the Warrant, the Company shall determine to
register any of its securities, either for its own account or the account of a
security holder or holders exercising their respective demand registration
rights, other an (i) a registration relating solely to employee benefit plans,
or (ii) a registration relating solely to a Securities and Exchange Commission
Rule 145 transaction, the Company will:

               (i)  promptly give to Holder written notice thereof; and

               (ii) include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests, made within 30 days after receipt of such written notice from the
Company by Holder, but only to the extent that such inclusion will not diminish
the number of securities included by the Company or by holders of the Company's
securities who have demanded such registration. The Company shall have the right
to terminate or withdraw any registration initiated by it prior to the
effectiveness of such registration whether or not Holder has elected to include
securities in such registration.

        5.     Anti-Dilution Adjustments.

        (a)    Stock Dividend. If the Company shall at any time declare a 
dividend payable in shares of Common Stock, then the Holder hereof, upon
Exercise of this Warrant after the record date for the determination of Holders
of Common Stock entitled to receive such dividend, shall be entitled to receive
upon Exercise of this Warrant, in addition to the number of shares of Common
Stock as to which this Warrant is Exercised, such additional shares of Common
Stock as such Holder would have received had this Warrant been Exercised
immediately prior to such record date and the Exercise Price will be
proportionately adjusted.

        (b)    Recapitalization or Reclassification. If the Company shall at any
time effect a recapitalization, reclassification or other similar transaction of
such character that the shares of Common Stock shall be changed into or become
exchangeable for a larger or smaller number of shares, then upon the effective
date thereof, the number of shares of Common Stock which the Holder hereof shall
be entitled to purchase upon Exercise of this Warrant shall be increased or
decreased, as the case may be, in direct proportion to the increase or decrease
in the number of shares of Common Stock by reason of such recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the
case of an increase in the number of shares, proportionally decreased and, in
the case of decrease in the number of shares, proportionally increased. The
Company shall give the Warrant Holder the same notice it provides to holders of
Common Stock of any transaction described in this Section 5(b).

        (c)    Distributions. If the Company shall at any time distribute to
Holders of Common Stock cash, evidences of indebtedness or other securities or
assets (other than cash dividends or distributions payable out of earned surplus
or net profits for the current or preceding year) then, in any such case, the
Holder of this Warrant shall be entitled to receive, upon exercise of this
Warrant, with 


                                     EX-60
<PAGE>   5

respect to each share of Common Stock issuable upon such Exercise, the amount of
cash or evidences of indebtedness or other securities or assets which such
Holder would have been entitled to receive with respect to each such share of
Common Stock as a result of the happening of such event had this Warrant been
Exercised immediately prior to the record date or other date fixing shareholders
to be affected by such event (the "Determination Date") or, in lieu thereof, if
the Board of Directors of the Company should so determine at the time of such
distribution, a reduced Exercise Price determined by multiplying the Exercise
Price on the Determination Date by a fraction, the numerator of which is the
result of such Exercise Price reduced by the value of such distribution
applicable to one share of Common Stock (such value to be determined by the
Board in its discretion) and the denominator of which is such Exercise Price.

        (d)    Notice of Consolidation or Merger. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock of the Company shall
be changed into the same or a different number of shares of the same or another
class or classes of stock or securities or other assets of the Company or
another entity or there is a sale of all or substantially all the Company's
assets (a "Corporate Change"), then this Warrant shall be assumed by the
acquiring entity or any affiliate thereof and thereafter this Warrant shall be
exerciseable into such class and type of securities or other assets as the
Holder would have received had the Holder exercised this Warrant immediately
prior to such Corporate Change; provided, however, that Company may not affect
any Corporate Change unless it first shall have given thirty (30) business days
notice to the Holder hereof of any Corporate Change.

        (e)    Exercise Price Adjusted. As used in this Warrant, the term 
"Exercise Price" shall mean the purchase price per share specified in Section 3
of this Warrant, as it may be adjusted from time to time, until the occurrence
of an event stated in subsection (a), (b) or (c) of this Section 5 and
thereafter shall mean said price as adjusted from time to time in accordance
with the provisions of said subsection. No such adjustment under this Section 5
shall be made unless such adjustment would change the Exercise Price at the time
by $.01 or more; provided, however, that all adjustments not so made shall be
deferred and made when the aggregate thereof would change the Exercise Price at
the time by $.01 or more. No adjustment made pursuant to any provision of this
Section 5 shall have the effect of increasing the total consideration payable
upon Exercise of this Warrant in respect of all the Common Stock as to which
this Warrant may be exercised. Notwithstanding anything to the contrary
contained herein, the Exercise Price shall not be reduced to an amount below the
par value of the Common Stock.

        (f)    Adjustments: Additional Shares, Securities or Assets. In the 
event that at any time, as a result of an adjustment made pursuant to this
Section 5, the Holder of this Warrant shall, upon Exercise of this Warrant,
become entitled to receive shares and/or other securities or assets (other than
Common Stock) then, wherever appropriate, all references herein to shares of
Common Stock shall be deemed to refer to and include such shares and/or other
securities or assets; and thereafter the number of such shares and/or other
securities or assets shall be subject to adjustment from time to time in a
manner and upon terms as nearly equivalent as practicable to the provisions of
this Section 5.

        6.     Fractional Interests.


                                     EX-61
<PAGE>   6

               No fractional shares or scrip representing fractional shares
shall be issuable upon the Exercise of this Warrant, but on Exercise of this
Warrant, the Holder hereof may purchase only a whole number of shares of Common
Stock. If, on Exercise of this Warrant, the Holder hereof would be entitled to a
fractional share of Common Stock or a right to acquire a fractional share of
Common Stock, such fractional share shall be disregarded and the number of
shares of Common Stock issuable upon conversion shall be the next higher number
of shares.

        7.     Reservation of Shares.

               The Company shall at all times reserve for issuance such number
of authorized and unissued shares of Common Stock (or other securities
substituted therefor as herein above provided) as shall be sufficient for
Exercise and payment of the Exercise Price of this Warrant. The Company
covenants and agrees that upon Exercise of this Warrant, all shares of Common
Stock issuable upon such Exercise shall be duly and validly issued, fully paid,
nonassessable and not subject to preemptive rights, rights of first refusal or
similar rights of any person or entity.

        8.     Restrictions on Transfer.

               (a) Registration or Exemption Required. This Warrant and the
Common Stock issuable on Exercise hereof have not been registered under the
Securities Act of 1933, as amended, and may not be sold, transferred, pledged,
hypothecated or otherwise disposed of in the absence of registration or the
availability of an exemption from registration under said Act. All shares of
Common Stock issued upon Exercise of this Warrant shall bear an appropriate
legend to such effect, if applicable.

               (b) Assignment. Assuming the conditions of (a) above regarding
registration or exemption have been satisfied, the Holder may sell, transfer,
assign, pledge or otherwise dispose of this Warrant, in whole or in part. Holder
shall deliver a written notice to Company, substantially in the form of the
Assignment attached hereto as Exhibit B, indicating the person or persons to
whom the Warrant shall be assigned and the respective number of warrants to be
assigned to each assignee. The Company shall effect the assignment within ten
days, and shall deliver to the assignee(s) designated by Holder a Warrant or
Warrants of like tenor and terms for the appropriate number of shares.

               (c) Investment Intent. The Warrant and Common Stock issuable upon
conversion are intended to be held for investment purposes and not with an
intent to distribution, as defined in the Act.

        9.     Benefits of this Warrant.

               Nothing in this Warrant shall be construed to confer upon any
person other than the Company and the Holder of this Warrant any legal or
equitable right, remedy or claim under this Warrant and this Warrant shall be
for the sole and exclusive benefit of the Company and the Holder of this
Warrant.

        10.    Applicable Law.

destruction or mutilation of this Warrant, and (in the case of loss, theft or
destruction) of indemnity or security reasonably satisfactory to the Company,

Warrant to Purchase
100,000 shares


                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                         PATRIOT SCIENTIFIC CORPORATION

        THIS CERTIFIES that SPELLCASTER TELECOMMUNICATIONS, INC. or any
subsequent ("Holder") hereof, has the right to purchase from PATRIOT SCIENTIFIC
CORPORATION, a Delaware corporation (the "Company"), not more than 100,000 fully
paid and nonassessable shares of the Company's Common Stock, par value $.00001
per share ("Common Stock"), at a price equal to the Exercise Price as defined in
Section 3 below, subject to adjustment as provided herein, at any time on or
before 5:00 p.m., San Diego, California time, on April 29, 2000.


        The Holder of this Warrant agrees with the Company that this Warrant is
issued and all rights hereunder shall be held subject to all of the conditions,
limitations and provisions set forth herein.

        1.     Date of Issuance.

        This Warrant shall be deemed to be issued on April 28, 1998 ("Date of
Issuance").

        2.     Exercise.

        (a) Manner of Exercise. This Warrant may be exercised as to all or any
lesser number of full shares of Common Stock covered hereby upon surrender of
this Warrant, with the Exercise Form attached hereto duly executed, together
with the full Exercise Price (as defined in Section 3) for each share of Common
Stock as to which this Warrant is exercised, at the office of the Company,
Patriot Scientific Corporation, 10989 Via Frontera, San Diego, California 92127,
Attention: President, Telephone No. 619-674-5000, Telecopy No. 619-674-5005, or
at such other office or agency as the Company may designate in writing, by
overnight mail, with an advance copy of the Exercise Form attached as Exhibit A
("Exercise Form") by facsimile (such surrender and payment of the Exercise Price
hereinafter called the "Exercise of this Warrant").


                                     EX-67
<PAGE>   3

        (b) Date of Exercise. The "Date of Exercise" of the Warrant shall be
defined as the date that the advance copy of the Exercise Form is sent by
facsimile to the Company, provided that the original Warrant and Exercise Form
are received by the Company within five (5) business days thereafter. The
original Warrant and Exercise Form must be received within five (5) business
days of the Date of Exercise, or the exercise may, at the Company's option, be
considered void. Alternatively, the Date of Exercise shall be defined as the
date the original Exercise Form is received by the Company, if Holder has not
sent advance notice by facsimile.

        (c) Cancellation of Warrant. This Warrant shall be canceled upon its
Exercise, and, as soon as practical after the Date of Exercise, the Holder
hereof shall be entitled to receive Common Stock for the number of shares
purchased upon such Exercise, and if this Warrant is not exercised in full, the
Holder shall be entitled to receive a new Warrant or Warrants (containing terms
identical to this Warrant) representing any unexercised portion of this Warrant
in addition to such Common Stock.

        (d) Holder of Record. Each person in whose name any Warrant for shares
of Common Stock is issued shall, for all purposes, be deemed to have become the
Holder of record of such shares on the Date of Exercise of this Warrant,
irrespective of the date of delivery of such shares of Common Stock. Nothing in
this Warrant shall be construed as conferring upon the Holder hereof any rights
as a shareholder of the Company.

        3.     Payment of Warrant Exercise Price.

        The Exercise Price ("Exercise Price") shall equal $ 1.25.

        Payment of the Exercise Price may be made by cash, certified or cashiers
check, or wire transfer.

        For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is
intended, understood and acknowledged that the Common Stock issuable upon
exercise of this Warrant shall be deemed to have been acquired at the time this
Warrant was exercised. Moreover, it is intended, understood and acknowledged
that the holding period for the Common Stock issuable upon exercise of this
Warrant shall be deemed to have commenced on the date this Warrant was
exercised.


        4.     Transfer Rights

        Subject to the provisions of Section 8 of this Warrant, this Warrant may
be transferred on the books of the Company, in whole or in part, in person or by
attorney, upon surrender of this Warrant properly endorsed. This Warrant shall
be canceled upon such surrender and, as soon as practicable thereafter, the
person to whom such transfer is made shall be entitled to receive a new Warrant
or Warrants as to the portion of this Warrant transferred, and the Holder of
this Warrant shall be entitled to receive a new Warrant or Warrants as to the
portion hereof retained.

        5.     Anti-Dilution Adjustments.


                                     EX-68
<PAGE>   4

        (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common Stock, then the Holder hereof, upon Exercise of this
Warrant after the record date for the determination of Holders of Common Stock
entitled to receive such dividend, shall be entitled to receive upon Exercise of
this Warrant, in addition to the number of shares of Common Stock as to which
this Warrant is Exercised, such additional shares of Common Stock as such Holder
would have received had this Warrant been Exercised immediately prior to such
record date and the Exercise Price will be proportionately adjusted.

        (b) Recapitalization or Reclassification. If the Company shall at any
time effect a recapitalization, reclassification or other similar transaction of
such character that the shares of Common Stock shall be changed into or become
exchangeable for a larger or smaller number of shares, then upon the effective
date thereof, the number of shares of Common Stock which the Holder hereof shall
be entitled to purchase upon Exercise of this Warrant shall be increased or
decreased, as the case may be, in direct proportion to the increase or decrease
in the number of shares of Common Stock by reason of such recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the
case of an increase in the number of shares, proportionally decreased and, in
the case of decrease in the number of shares, proportionally increased. The
Company shall give the Warrant Holder the same notice it provides to holders of
Common Stock of any transaction described in this Section 5(b).

        (c) Distributions. If the Company shall at any time distribute to
Holders of Common Stock cash, evidences of indebtedness or other securities or
assets (other than cash dividends or distributions payable out of earned surplus
or net profits for the current or preceding year) then, in any such case, the
Holder of this Warrant shall be entitled to receive, upon exercise of this
Warrant, with respect to each share of Common Stock issuable upon such Exercise,
the amount of cash or evidences of indebtedness or other securities or assets
which such Holder would have been entitled to receive with respect to each such
share of Common Stock as a result of the happening of such event had this
Warrant been Exercised immediately prior to the record date or other date fixing
shareholders to be affected by such event (the "Determination Date") or, in lieu
thereof, if the Board of Directors of the Company should so determine at the
time of such distribution, a reduced Exercise Price determined by multiplying
the Exercise Price on the Determination Date by a fraction, the numerator of
which is the result of such Exercise Price reduced by the value of such
distribution applicable to one share of Common Stock (such value to be
determined by the Board in its discretion) and the denominator of which is such
Exercise Price.

        (d) Notice of Consolidation or Merger. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock of the Company shall
be changed into the same or a different number of shares of the same or another
class or classes of stock or securities or other assets of the Company or
another entity or there is a sale of all or substantially all the Company's
assets (a "Corporate Change"), then this Warrant shall be assumed by the
acquiring entity or any affiliate thereof and thereafter this Warrant shall be
exerciseable into such class and type of securities or other assets as the
Holder would have received had the Holder exercised this Warrant immediately
prior to such Corporate Change; provided, however, that Company may not affect
any Corporate Change unless it first shall have given thirty (30) business days
notice to the Holder hereof of any Corporate Change.


                                     EX-69
<PAGE>   5

        (e)    Exercise Price Adjusted. As used in this Warrant, the term 
"Exercise Price" shall mean the purchase price per share specified in Section 3
of this Warrant, as it may be adjusted from time to time, until the occurrence
of an event stated in subsection (a), (b) or (c) of this Section 5 and
thereafter shall mean said price as adjusted from time to time in accordance
with the provisions of said subsection. No such adjustment under this Section 5
shall be made unless such adjustment would change the Exercise Price at the time
by $.01 or more; provided, however, that all adjustments not so made shall be
deferred and made when the aggregate thereof would change the Exercise Price at
the time by $.01 or more. No adjustment made pursuant to any provision of this
Section 5 shall have the effect of increasing the total consideration payable
upon Exercise of this Warrant in respect of all the Common Stock as to which
this Warrant may be exercised. Notwithstanding anything to the contrary
contained herein, the Exercise Price shall not be reduced to an amount below the
par value of the Common Stock.

        (f)    Adjustments: Additional Shares, Securities or Assets. In the 
event that at any time, as a result of an adjustment made pursuant to this
Section 5, the Holder of this Warrant shall, upon Exercise of this Warrant,
become entitled to receive shares and/or other securities or assets (other than
Common Stock) then, wherever appropriate, all references herein to shares of
Common Stock shall be deemed to refer to and include such shares and/or other
securities or assets; and thereafter the number of such shares and/or other
securities or assets shall be subject to adjustment from time to time in a
manner and upon terms as nearly equivalent as practicable to the provisions of
this Section 5.

        6.     Fractional Interests.

               No fractional shares or scrip representing fractional shares
shall be issuable upon the Exercise of this Warrant, but on Exercise of this
Warrant, the Holder hereof may purchase only a whole number of shares of Common
Stock. If, on Exercise of this Warrant, the Holder hereof would be entitled to a
fractional share of Common Stock or a right to acquire a fractional share of
Common Stock, such fractional share shall be disregarded and the number of
shares of Common Stock issuable upon conversion shall be the next higher number
of shares.

        7.     Reservation of Shares.

               The Company shall at all times reserve for issuance such number
of authorized and unissued shares of Common Stock (or other securities
substituted therefor as herein above provided) as shall be sufficient for
Exercise and payment of the Exercise Price of this Warrant. The Company
covenants and agrees that upon Exercise of this Warrant, all shares of Common
Stock issuable upon such Exercise shall be duly and validly issued, fully paid,
nonassessable and not subject to preemptive rights, rights of first refusal or
similar rights of any person or entity.

        8.     Restrictions on Transfer.

               (a) Registration or Exemption Required. This Warrant and the
Common Stock issuable on Exercise hereof have not been registered under the
Securities Act of 1933, as amended, and may not be sold, transferred, pledged,
hypothecated or otherwise disposed of in the absence of registration or the
availability of an exemption from registration under said Act. All shares of
Common 


                                     EX-70
<PAGE>   6

Stock issued upon Exercise of this Warrant shall bear an appropriate legend to
such effect, if applicable.

               (b) Assignment. Assuming the conditions of (a) above regarding
registration or exemption have been satisfied, the Holder may sell, transfer,
assign, pledge or otherwise dispose of this Warrant, in whole or in part. Holder
shall deliver a written notice to Company, substantially in the form of the
Assignment attached hereto as Exhibit B, indicating the person or persons to
whom the Warrant shall be assigned and the respective number of warrants to be
assigned to each assignee. The Company shall effect the assignment within ten
days, and shall deliver to the assignee(s) designated by Holder a Warrant or
Warrants of like tenor and terms for the appropriate number of shares.

               (c) Investment Intent. The Warrant and Common Stock issuable upon
conversion are intended to be held for investment purposes and not with an
intent to distribution, as defined in the Act.

        9.     Benefits of this Warrant.

               Nothing in this Warrant shall be construed to confer upon any
person other than the Company and the Holder of this Warrant any legal or
equitable right, remedy or claim under this Warrant and this Warrant shall be
for the sole and exclusive benefit of the Company and the Holder of this
Warrant.

officer, member, employee or agent of another corporation or partnership, joint

        given to you by the Board and you have had a reasonable opportunity to
        cure such breach. Notwithstanding the foregoing, the Employee shall not
        be deemed to have been terminated for Cause unless and until there shall
        have been delivered to the Employee (i) a copy of a resolution, duly
        adopted by the Board (excluding the Employee) at a meeting of the Board
        called and held for the purpose (after reasonable notice to the Employee
        of the meeting of the Board at which the motion is to be considered,
        which notice shall specify in reasonably detailed terms the facts and
        circumstances constituting Cause, and after the Employee, together with
        his counsel, having been afforded at such meeting an opportunity to be
        heard before the Board), finding that the Employee was guilty of conduct
        constituting Cause; (ii) a certificate of the Secretary or an Assistant
        Secretary of the Company stating that such resolution was in fact duly

        Termination in the form specified in the following sentence. A Notice of
        Termination shall indicate the specific termination provision in this
        Agreement relied upon and set forth in reasonable detail the

        employment hereunder and Employee's compensation and other rights under
        this Agreement and as an employee of the Company (except as to
        compensation rights accrued prior thereto and except as expressly
        provided in the next succeeding sentence) shall terminate thirty (30 )
        days following the date of death. In such event, the Company shall pay
        to the Employee's designated executor or administrator of the Employee's
        estate, all compensations and benefits accrued which would otherwise be
        payable to the Employee through the thirtieth (30) day following the
        date of death.

        (4) If the Employee is unable for any reason to carry out or to perform
        the duties required of him hereunder and does not resume his duties
        prior to the termination date specified in the Company's written notice
        of termination; provided, however, if the Employee shall fail to carry
        out or to perform the duties required of him because of mental or
        physical disability for a six consecutive month period during the term
        hereof and following such period he is unable to perform his duties
        hereunder because of mental or physical disability, as determined by the
        Board of Directors of the Company, or a duly authorized committee
        thereof, acting in good faith and upon reasonable grounds, he shall be
        entitled to receive his then Base Salary he would otherwise be entitled
        to hereunder during the term of this Agreement pursuant to Paragraph 3
        hereof for a period of not longer than twelve (12) months after the

        months of his then monthly Base Salary and any bonus on an as if
        perfected basis payable in one lump sum within thirty (30) days after

        "Exchange Act"); provided that, without limitation, such a change in
        control or other qualifying event shall be deemed to have occurred if
        (i) any "person" (as such term is used in Sections 13(d) and 14(d) of
        the Exchange Act) is or becomes the "beneficial owner" (as defined in

4.  Termination of Employment.


                                     EX-84
<PAGE>   4

        (a) The employment of the Executive hereunder shall automatically
terminate if the Executive shall die during the Term of Employment. The
employment of the Executive can be terminated for cause by the Company at its
option only for the following:

        (1) the conviction of the Executive under state or federal law of a
felony or other crime, or the equivalent under foreign law; unless in any such
case Executive performed such act in good faith and in a manner reasonably
believed to be in or not opposed to the best interests of the Company;

        (2) the material breach by Executive of any provision of the Agreement
which has not been cured pursuant to the provisions of Section 5 hereof; or

        (3) a determination or request by an appropriate regulatory authority
that the Executive be removed or disqualified from acting as an officer of the
Company.

        (b) If the Executive's employment is terminated for other than cause by
the Company, then the Executive is entitled to severance payments equal to four
(4) months of the current base salary payable in a lump sum payment on the last
day of the thirty (30) day notice period;

        (c) The Executive shall have the right as his sole option to terminate
his employment at any time upon ninety (90) days written notice or for such
other notice period to be determined by the President and CEO in his sole
discretion.

        (d) If within twelve (12) months of a Change in Control, as that term is
defined herein, Executive's employment is terminated for other than cause or
Executive refused to accept or voluntarily resigns from a position other than a
Qualified Position, as that term is defined herein, Executive shall receive
severance compensation equal to twelve (12) months of his then current base
salary. A "Change in Control" means the acquisition, directly or indirectly of
more than 40% of the outstanding shares of any class of voting securities of the
Company by one person or one entity that is not an existing shareholder as of
the date of this Agreement, or a merger, consolidation or sale of all or
substantially all of the assets of the Company, such that the individuals
constituting the Board of the Company immediately prior to such period shall
cease to constitute a majority of the Board, unless the election of each
director who was not a director prior thereto was approved by vote of at least
two-thirds of the directors then in office who were directors prior to such
period. Notwithstanding the foregoing, an acquisition of the requisite
percentage of voting securities in connection with a public offering of
securities by the Company for the primary purpose of providing capital resources
to the Company shall not be considered a "Change in Control" for purposes of
this Section 4(d). "Qualified Position" is an executive officer position with
the entity surviving the Change in Control with substantially the same
responsibilities as those held by the Executive on the date of the Change in
Control. Also, notwithstanding the foregoing, if the Company determines that the
amounts payable to Executive under this employment agreement, when considered
together within the other amounts payable to Executive as a result of a Change
in Control, cause such payments to be treated as excess parachute payments
within the meaning of Section 280G of the Internal Revenue Code, the Company
shall reduce the amount payable to Executive under this Section 4(d) to an
amount that will not subject Executive to the imposition of tax under Section


                                     EX-85
<PAGE>   5

4999 of the Internal Revenue Code; provided, however, that this provision shall
apply only to payments to be made under this employment agreement and shall not
cause the reduction of any other payments to be made to Executive by the
Company.

5. Notice of Breach. The Company and the Executive agree that, prior to the
termination of the Employment Period by reason of any breach of any provision of
the Agreement, the injured party will give the party in breach written notice,
specifying such breach and permitting the party in breach to cure such breach
within a period of thirty (30) days after receipt of such notice, except a
breach by Executive of provisions of Section 7 of this Agreement shall not have
a cure period.

6.  Indemnification.

        (a) If, after the date of the commencement of the Employment Period, the
Executive is made a party or is threatened to be made a party to any action ,
suit or proceeding, whether civil, criminal, administrative or investigative (a
"Proceeding"), by reason of the fact that he is or was a director or officer of
the Company or is or was serving at the request of the Company as a director,
officer, member, employee or agent of another corporation or partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether or not the basis of such Proceeding is an alleged act or
failure to act in an official capacity as a director, officer, member, employee
or agent, he shall be indemnified and held harmless by the Company to the
fullest extent authorized by Delaware law, as the same exists or may hereafter
be amended, against all expense, liability and loss (including, without
limitation, attorney's fees, judgments, fines and amounts paid or to be paid in
settlement) reasonably incurred or suffered by the Executive in connection
herewith, including , without limitation, payment of expenses incurred in
defending a Proceeding prior to the final disposition of such Proceeding
(subject to receipt of an undertaking by the Executive to repay such amount if
it shall ultimately be determined that the Executive is not entitled to be
indemnified by the Company under Delaware law), and such indemnification shall
continue as to the Executive even if he has ceased to be a director, officer,
member, employee or agent of the Company or other enterprise and shall inure to
the benefit of his heirs, executors and administrators.

        (b) The right of indemnification and the payment of expenses incurred in
defending a Proceeding in advance of its final disposition conferring in this
Section 6 shall not be exclusive of any other right that the Executive may have
or hereafter may acquire under any statute, provision of the Certificate of
Incorporation or Bylaws of the Company, agreement, vote of shareholders or
disinterested directors or otherwise.

7.  Trade Secrets of the Company, Patents and Inventions.

shall be approved by the Board and Compensation Committee.

        (b) The Executive is entitled, at the discretion of the Board of
Directors of the Company, to an Annual Incentive Bonus up to 50% of the total
yearly base compensation for the applicable year (the "Annual Incentive Bonus").
The Annual Incentive Bonus payment will be based upon mutually agreed upon
objectives and levels of performance.

        (c) The Executive shall be eligible to participate in all employee
benefit programs, if any, maintained by the Company, including, but not limited
to, group life insurance, medical, dental, retirement and pension plans, any
deferred compensation profit sharing plans, 401(k) savings plan, and other such
fringe benefits as are or may be available from time to time to senior
executives of the Company. During the Employment Period, the Executive is
entitled to 4 weeks vacation per annum.

        (d) The Company will pay or reimburse the Executive during the
Employment Period for all expenses normally reimbursed by the Company and
reasonably incurred by the Executive in furtherance of his duties hereunder and
authorized by the Company, including but not limited to, expenses of
entertainment, travel, meals, hotel accommodations and the like upon the
submission of the Executive of vouchers or an itemized list thereof and as may
be required in order to permit such payments as proper deductions for the
Company under the Internal Revenue Code of 1986 and the rules and regulations
adopted pursuant thereto now or hereafter in effect.

3.  Termination of Employment.

        (a) The employment of the Executive hereunder shall automatically
terminate if the Executive shall die during the Term of Employment. The
employment of the Executive can be terminated for cause by the Company at its
option only for the following:

        (1) The conviction of the Executive under state or federal law of a
felony or other crime, or the equivalent under foreign law; unless in any such
case Executive performed such act in good faith and in a manner reasonably
believed to be in or not opposed to the best interests of the Company;

        (2) the material breach by Executive of any provision of the Agreement
which has not been cured pursuant to the provisions of Section 4 hereof; or

        (3) a determination or request by an appropriate regulatory authority
that the Executive be removed or disqualified from acting as an officer of the
Company.

        (b) If the Executive's employment is terminated for other than cause by
the Company, then the Executive is entitled to severance payments equal to four
(4) months of the current base salary payable in a lump sum payment on the last
day of the thirty (30) day notice period;


                                     EX-93
<PAGE>   4

        (c) The Executive shall have the right as his sole option to terminate
his employment at any time upon ninety (90) days written notice or for such
other notice period to be determined by the President and CEO in his sole
discretion.

        (d) If within twelve (12) months of a Change in Control, as that term is
defined herein, Executive's employment is terminated for other than cause or
Executive refused to accept or voluntarily resigns from a position other than a
Qualified Position, as that term is defined herein, Executive shall receive
severance compensation equal to twelve (12) months of his then current base
salary. A "Change in Control" means the acquisition, directly or indirectly of
more than 40% of the outstanding shares of any class of voting securities of the
Company by one person or one entity that is not an existing shareholder as of
the date of this Agreement, or a merger, consolidation or sale of all or
substantially all of the assets of the Company, such that the individuals
constituting the Board of the Company immediately prior to such period shall
cease to constitute a majority of the Board, unless the election of each
director who was not a director prior thereto was approved by vote of at least
two-thirds of the directors then in office who were directors prior to such
period. Notwithstanding the foregoing, an acquisition of the requisite
percentage of voting securities in connection with a public offering of
securities by the Company for the primary purpose of providing capital resources
to the Company shall not be considered a "Change in Control" for purposes of
this Section 3(d). "Qualified Position" is an executive officer position with
the entity surviving the Change in Control with substantially the same
responsibilities as those held by the Executive on the date of the Change in
Control. Also, notwithstanding the foregoing, if the Company determines that the
amounts payable to Executive under this employment agreement, when considered
together within the other amounts payable to Executive as a result of a Change
in Control, cause such payments to be treated as excess parachute payments
within the meaning of Section 280G of the Internal Revenue Code, the Company
shall reduce the amount payable to Executive under this Section 3(d) to an
amount that will not subject Executive to the imposition of tax under Section
4999 of the Internal Revenue Code; provided, however, that this provision shall
apply only to payments to be made under this employment agreement and shall not
cause the reduction of any other payments to be made to Executive by the
Company.

4. Notice of Breach. The Company and the Executive agree that, prior to the
termination of the Employment Period by reason of any breach of any provision of
the Agreement, the injured party will give the party in breach written notice,
specifying such breach and permitting the party in breach to cure such breach
within a period of thirty (30) days after receipt of such notice, except a
breach by Executive of provisions of Section 6 of this Agreement shall not have
a cure period.

5.  Indemnification.

        (a) If, after the date of the commencement of the Employment Period, the
Executive is made a party or is threatened to be made a party to any action,
suit or proceeding, whether civil, criminal, administrative or investigative (a
"Proceeding"), by reason of the fact that he is or was a director or officer of
the Company or is or was serving at the request of the Company as a director,
officer, member, employee or agent of another corporation or partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether or not the basis of such Proceeding is an alleged act or
failure to act in an official capacity as a director, officer, member, employee
or agent, he shall be indemnified and held harmless by the Company to the
fullest extent 


                                     EX-94
<PAGE>   5

authorized by Delaware law, as the same exists or may hereafter be amended,
against all expense, liability and loss (including, without limitation,
attorney's fees, judgments, fines and amounts paid or to be paid in settlement)
reasonably incurred or suffered by the Executive in connection herewith,
including , without limitation, payment of expenses incurred in defending a
Proceeding prior to the final disposition of such Proceeding (subject to receipt
of an undertaking by the Executive to repay such amount if it shall ultimately
be determined that the Executive is not entitled to be indemnified by the
Company under Delaware law), and such indemnification shall continue as to the
Executive even if he has ceased to be a director, officer, member, employee or
agent of the Company or other enterprise and shall inure to the benefit of his
heirs, executors and administrators.

        (b) The right of indemnification and the payment of expenses incurred in
defending a Proceeding in advance of its final disposition conferring in this
Section 6 shall not be exclusive of any other right that the Executive may have
or hereafter may acquire under any statute, provision of the Certificate of
Incorporation or Bylaws of the Company, agreement, vote of shareholders or
disinterested directors or otherwise.

6.  Trade Secrets of the Company, Patents and Inventions.

        (a) Except as required by the performance of the Executive's services to
the Company under the terms of this Agreement, neither the Executive or any of
his agents or representatives, shall, during his employment and for so long
afterwards as the pertinent information or data remain Confidential Information,
directly or indirectly, make use of, permit others to use, divulge, disseminate,
copy or otherwise disclose the Company's Confidential Information and/or
Inventions as defined by subparagraphs (i) and (ii), respectively.
        (i) "Confidential Information" means all information and material which
is proprietary to the Company, whether or not marked as "confidential" or
"proprietary" and which is disclosed to or obtained from the Company by the
Executive, which relates to the Company' past, present or future research,
development or business activities. Confidential Information is all information
or materials prepared by or for the Company and includes, without limitation,
all of the following: designs, drawings, specifications, techniques, models,

customers, suppliers or personnel, contract forms, pricing policies and
financial information, volumes of sales, and other information of similar
nature, whether or not reduced to writing or other tangible form, and any other
Trade Secrets, as defined by subparagraph (iii), or non-public business
information. Confidential Information does not include any information which (1)
was in the lawful and unrestricted possession of the Executive prior to its
disclosure by the Company, (2) is or becomes generally available to the public
by acts other than those of the Executive after receiving it, or (3) has been
received lawfully and in good faith by the Executive from a third party who did
not derive it from the Company.

        (ii) "Inventions" means and all discoveries, concepts and ideas, whether
patentable or not, including but not limited to, processes, methods, formulas,
compositions, techniques, articles and machines, as well as improvements thereof
or "know-how" related thereto, relating at the time of 


                                     EX-95
<PAGE>   6

conception or reduction to practice to the business engaged in by the Company,
or any actual or anticipated research or development by the Company.

        (iii) "Trade Secrets" shall mean any scientific or technical data,
information, design, process, procedure, formula or improvement that is
commercially available to the Company and is not generally known in the
industry.

Materials involving Confidential Information and Inventions are the exclusive
property of the Company and shall not be removed under any circumstances from
the premises of the Company where the work is being carried on without prior
written consent of the Company except when consistent with the Company's normal
business practices.

        (b) The Executive agrees that any inventions made, conceived or
completed by him during the term of his employment, solely or jointly with
others, which are made with the Company's equipment, supplies, facilities or
Confidential Information, or which relate at the time of conception or reduction
to purpose of the invention to the business of the Company or the Company's
actual or demonstrably anticipated research and development, or which result
from any work performed by the Executive for the Company, shall be the sole and
exclusive property of the Company. The Executive promises to assign such
inventions to the Company. The Executive also agrees that the Company shall have
the right to keep such inventions as trade secrets, if the Company chooses. The
Executive agrees to assign to the Company the Executive's rights in any other
inventions where the Company is required to grant those rights to the United
States government or any agency thereof. In order to permit the Company to claim
rights to which it may be entitled, the Executive agrees to disclose to the
Company in confidence all inventions which the Executive makes arising out of
the Executive's employment and all patent applications filed by the Executive
within one year after the termination of his employment.

        (c) The Executive shall assist the Company in obtaining patents on all
inventions, designs, improvements and discoveries patentable by the Company in
the United States and in all foreign countries, and shall execute all documents
and do all things necessary to obtain letters patent, to vest the Company with
full and extensive title thereto, and to protect the same against infringement
by others.

7. Severability In the event that any provisions or portion of this Agreement
shall be determined to be invalid or unenforceable for any reason, in whole or
in part, the remaining provisions of this Agreement shall be unaffected thereby
and shall remain in full force and effect to the fullest extent permitted by
law.

8. Assignment. The rights of the Company (but not its obligations) under this
Agreement may, without the consent of the Executive, be assigned by the Company
to any parent, subsidiary, or a successor of the Company; provided that such
parent, subsidiary or successor acknowledges in writing that it is also bound by
the terms and obligations of this Agreement. Except as provided in the preceding
sentence, the Company may not assign all or any of its rights, duties or
obligations hereunder without the prior written consent of the Executive. Except
as provided for in Section 10 hereunder, the Executive may not assign all or any
of his rights, duties or obligations hereunder without the prior written consent
of the Company.


                                     EX-96
<PAGE>   7

Paragraph 6 of this Agreement shall survive termination of the Executive's
employment and/or this Agreement, and shall remain in full force and effect
regardless of the cause of such termination.

10. Beneficiaries; References. The Executive shall be entitled to select (and
change) a beneficiary or beneficiaries to receive any compensation or benefit
payable following the Executive's death, and may change such election, in either
case, by giving the Company written notice thereof. In the event of the
Executive's death or a judicial determination of his incompetence, reference in
this Agreement shall be deemed, where appropriate, to refer to the Executive's
beneficiary, estate, committee, conservator or other legal representative.

relationship, including any disputes upon termination, all such disputes shall
be resolved by binding arbitration before a single neutral arbitrator. The
arbitrator shall be selected from the "American Arbitration Association." The
arbitration shall be held in San Diego, California. The arbitrator is bound to

<PAGE>   8

provided within this employment agreement. The Executive's sole remedies, are
those set forth in this employment agreement. The arbitrator shall determine a
"prevailing party" and shall award such prevailing party (i) attorney's fees and
costs and (ii) the prevailing party's portion of the costs of arbitration.

In the event of any dispute between the Company and the Executive concerning any
ownership, use or disclosure of the Company's Confidential Information or other
intellectual property, the requirement of arbitration may be waived, at the
Company's sole election, and any such dispute may be brought before a court
having jurisdiction of the matter.

counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument. It shall not be necessary
in making proof of this Agreement to produce or account for more than one
original counterpart.

16. Entire Agreement. This Agreement contains the entire agreement of the
parties hereto and may be modified or amended only by a written instrument
executed by the parties hereto. Effective on the first day of the Employment
Period, any prior employment agreements between the Company and the Executive
shall terminate.

17. Good Faith. Each of the parties hereto agrees that he or it shall act in
good faith in all actions taken under this Agreement.

18. Waiver. No waiver of any of the provisions of this Agreement shall be deemed
to be or shall constitute a waiver of any other provision of the Agreement,
whether or not similar, nor shall any waiver constitute a continuing waiver. No
waiver of any provision of this Agreement shall be binding upon the parties
hereto unless it is executed in writing by the party making the waiver.

IN WITNESS WHEREOF, the parties hereto have executed the Agreement as of the day
and year first above written.
