  Industry Background
 
     Since its inception in 1984, the Company has been the leading developer and
supplier of proprietary security products that prevent unlicensed use and piracy
of software, and products that protect the confidentiality of digital content
transmitted over telecommunications systems. The Company applies "encryption"
technology in all of its security products. Encryption is the process of making
data indecipherable to anyone other than authorized users. The computer and
software industries have evolved from a market comprised primarily of stand
alone personal computers and single licensed software programs to a market where
computers are connected to networks, including the Internet, and software
licenses are purchased for multiple users within entire enterprises. The Company
has kept pace with the evolving market by applying its encryption expertise to

     The Company believes that the increased use and acceptance of computer
network and Internet communications to distribute Web-based content and conduct
electronic commerce have caused computer network security to become a paramount
business concern. The Company also believes that business needs for secure,
reliable and scalable computer network and Internet communications provide a
substantial market opportunity for the Company's security products and services.
A recent industry report from International Data Corporation (IDC) estimates
that the number of Internet users will grow from 97 million in 1998 to 320
million by 2002 with commensurate growth in electronic commerce from $32 billion
to $426 billion over that same period. In addition, the Company believes that
the market for the electronic delivery of digital content will continue to grow
rapidly. For example, IDC estimates that the worldwide market for Internet
software distribution will increase from approximately $200 million in 1997 to
approximately $5.9 billion by 2001, a 133% compound annual growth rate.
 
     The Company expects to take advantage of the anticipated explosive growth
in Internet commerce and communications by expanding its market and product
focus to improve and broaden its encryption technology to offer new computer
network security products and services supporting Internet commerce and

SOFTWARE PROTECTION PRODUCTS
 
     The Company's Software Protection Products combine sophisticated hardware
and software encryption technology to prevent the illegal distribution and use
of software. When software is protected by the Company's Sentinel suite of
hardware products (the "key"), the software program sends queries to the key
that is attached to the parallel port of the computer. The key immediately
evaluates each query and responds. The correct response ensures that standard
operation of the software will continue without interruption. If the key is not
present, the software will not operate. The keys incorporate the Company's
proprietary "algorithms" programmed into Company designed "ASIC" computer chips.
An algorithm is a mathematical procedure for manipulating digital information
with the intent of securing the information. An "ASIC" or "Application Specific
Integrated Circuit" is a logic circuit designed for a specific usage and
implemented in an integrated circuit. Once Sentinel protection is implemented,
developers need only include a Sentinel key with each software package shipped.
The end-user installs the software as usual, then simply plugs the enclosed
Sentinel key into the appropriate port on their computer.
 
     The Company also offers software-based products that provide software
license management and that provide secure software distribution over the
Internet. These products offer software developers greater flexibility in how
their products are licensed and distributed.
 
     The Company's Software Protection Products include:

INFORMATION SECURITY PRODUCTS
 
     The Company believes the importance of protecting the privacy and security
of satellite and computer network communications has increased in direct
proportion to technological advances, capabilities and overall growth in
telecommunications industries. Information security remains critical to
government and defense applications, and is increasingly valued by private
sector businesses to protect communications. The Company's Information Security
Products are comprised of ASIC circuits, electronic assemblies and equipment to
encrypt electronic communications, and are designed and developed by the Company
for use in government and commercial applications.
 
     The Company sells its products to the U.S. Government, approved foreign
governments and other markets that require the highest level of security. In
these sales, the Company enters into development contracts with the U.S.
Government, aerospace and related industry contractors. Under development
contracts, the Company typically agrees to provide engineering services for the
development of an "ASIC" circuit or other electronic assembly for the customer's
particular application. The Company usually serves as the prime contractor or as
a subcontractor, with either fixed-price or cost-plus-fixed-fee terms. Contracts
with the U.S. Government for 1998 accounted for approximately 67% of revenues
received by the Company from sales of its Information Security Products.
 
     The Company's Information Security Products are currently categorized into
four general areas of customer applications:
 
     SPACE-BASED PRODUCTS. These products are comprised of ASIC circuits and
electronic assemblies to decrypt (unscramble) satellite command links, and
encrypt (scramble) the communications that provide vital information about the
satellite (telemetry).
 
     GROUND-BASED COMMUNICATIONS PRODUCTS. These ASIC circuits, electronic
assemblies and equipment encrypt satellite command links and decrypt telemetry
links.
 
     VOICE COMMUNICATIONS PRODUCTS. These consist of ASIC circuits, electronic
assemblies and equipment that encrypt and decrypt voice transmissions over radio
or telephone communications networks.
 
     DATA COMMUNICATIONS PRODUCTS. These products, which are comprised of ASIC
circuits, electronic assemblies and equipment, encrypt and decrypt data or
digital information transmitted over communications networks or into storage
media.
 
INTERNET SECURITY PRODUCTS
 
     The Company's Internet Security Products use patent-pending technology to
provide Internet commerce companies and manufacturers of Internet computer
servers, firewalls, routers and switching equipment with increased security and
accelerated Internet commerce transaction capabilities. A "firewall" is
technology used for preventing unwanted inbound or outbound data at the boundary
of a computer network based upon a set of established rules. A "router" is a
computer networking device that is responsible for directing the "route" data
will travel enroute to its final destination.
 
     The Company's Internet Security Products also include portable security
tokens that offer a security solution to a variety of computer network, Internet
and information control issues, including secure access to Virtual Private
Networks.
 
     The Company's Internet Security Products include:
 
     CRYPTOSWIFT. A high performance security co-processor for Internet computer
transaction servers engaged in Internet commerce, electronic brokerage,
financial services and other applications that require security functions of
privacy and strong user authentication. It economically addresses the problem of
server overload due to the calculation intense mathematics associated with
"public key" encryption. This form of encryption is widely deployed in all Web
servers and browsers in use today and is the basis for Secure Sockets Layer
(SSL) and Secure Electronic Transaction (SET) protocols. CryptoSwift is an
industry standard PCI bus card with a proprietary ASIC co-processor. Using
patent pending "wide integer" multipliers, it performs
 
                                        4
<PAGE>   6
 
all the mathematics associated with public key encryption, allowing the server

proprietary "FastMap" encryption processor. NetSwift also provides manufacturers
with a scaleable security solution. Multiple NetSwift cards can be added to
computer hardware equipment to increase "IPSec" performance. "IPSec" is a
computer network security protocol that provides for confidentiality and
integrity of data transmitted over a computer network using the Internet
protocol technology.
 
     I-KEY. i-Key is a security token that can serve as a solution to a wide
variety of computer security and information control issues. The i-Key can be
plugged into any standard computer "USB port," and can serve to authenticate
users for ensuring secure access to Virtual Private Networks and computer
network equipment. A "USB port" is a standard connectivity technology included
on most new computers, servers and portable computer devices. Through user
identification data contained in each i-Key, the network is able to grant access
according to the user's authorization level.
 
     I-GUARD. i-Guard is a technology that provides Web-based content developers
with a security framework that securely authenticates the user's computer as the
user seeks access to a Web site. The technology is based upon Intel's recently
introduced Pentium(TM) III processor serial number reference implementation. The
i-Guard enables Web developers to incorporate machine authentication into their
applications by transparently downloading a "secured agent" to the user's
computer to authenticate the identity of the user's computer where the user
seeks access to a Web site.

chip. If the supplier is unable to fulfill the Company's requirements, the
Company may experience an interruption in the production of its Internet
Security Products until an alternative source of supply is developed. The
Company maintains a six-month inventory of ASIC chips in order to limit the
potential for such an interruption. The Company believes that there are a number
of companies capable of commencing the manufacture of its ASIC chips within six
months of such an interruption.
 
BACKLOG
 
     The Company manufactures its Software Protection Products and Internet
Security Products on the basis of its forecast of near-term demand and maintains
inventory in advance of receipt of firm customer orders. Orders from software
publishers are generally placed on an "as needed" basis and are usually shipped
by the Company within one week after receipt of the order. For these reasons,
the Company's backlog of Software Protection Product orders at any particular
time is generally not large and not indicative of future sales levels.
 
     As of December 31, 1998, the backlog for the Company's Information Security
Products represented in excess of five months of revenues. Actual revenue
recognition of the backlog mix of contracts can vary from three months to two
years.
 
INTELLECTUAL PROPERTY
 
     The Company believes that the value of its security products is dependent
upon its proprietary algorithms and encryption techniques remaining "trade
secrets." The Company has obtained copyright protection on
                                        7
<PAGE>   9
 
certain of its products and trademark protection for certain of its trade names.
The Company also owns several patents for its Information Security Products, and
the Company has U.S. Patent applications for certain technology included in its
Internet Security Products. There can be no assurance that the Company's
proprietary technology will remain a secret or that others will not develop
similar technology and use such technology to compete with the Company. There
can be no assurance that if the Company decides to apply for additional patents
in the future for any of its products, or on any new technology or products
derived therefrom, that patents will be granted.
 
COMPETITION
 
     SOFTWARE PROTECTION PRODUCTS
 
     The worldwide software and information protection industry is highly
competitive and characterized by rapid technological advances in both computer
hardware and software development. The Company believes it is the industry
leader with an estimated 30% worldwide market share. The Company's principal
competitors are Aladdin Knowledge Systems, Ltd., SCM Microsystems, Inc., and
Macrovision Corporation. The Company believes that it offers the most cost
effective Software Protection Products available to software publishers.
Although certain of the Company's competitors offer lower prices, the Company
believes that its technical support services and the ease of implementation of
its products favorably distinguish the Company from its competitors.
 
     INFORMATION SECURITY PRODUCTS
 
     The Company's principal competitors for its Information Security Products
are Motorola, Inc., VLSI Technology, Inc., Group Technologies, Inc., and Cylink
Corporation. The Company believes its unique products, encryption expertise and
large number of U.S. Government endorsed products are a significant competitive
advantage.
 
     INTERNET SECURITY PRODUCTS
 
     The Company's competitors for its current Internet Security Products are
hi/fn, inc., n-Cipher, Inc., Chrysalis Symbolic Design, Inc. and Information
Resource Engineering, Inc. The Company was first to deliver an encryption
accelerator product to improve the performance of Internet transaction servers.
The Company believes it is the leading supplier of accelerator products into the
Internet server market.
 
EMPLOYEES
 
     The Company presently employs approximately 413 full-time employees divided
among sales and marketing, manufacturing, research and development and
administration. The Company believes that its employee relations are excellent.
The employees and the Company are not parties to collective bargaining
agreements.

    fully impaired investment.
 
ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION
 
     The following is management's discussion and analysis of certain
significant factors that have affected the profitability of the Company's
business segments (Software Protection Products, Information Security Products,
and Internet Security Products) and its consolidated results of operations and
financial condition during the periods included in the accompanying consolidated
financial statements. The results of operations and financial condition reflect
the impact of the acquisition of SSI which was accounted for using the pooling-
of-interests method. The following should be read in conjunction with the
consolidated financial statements and related notes.
 
1998 COMPARED WITH 1997
 
     Software Protection Products revenue for the year ended December 31, 1998
decreased 5% to $57,238,000 as compared with 1997. The decline in revenue was
primarily due to the economic problems in Asia and other emerging markets.
Revenues in European markets increased 9% in 1998 as compared with 1997. The
average selling price per product for the year ended December 31, 1998 decreased
approximately 7% from the year ended December 31, 1997.
 
     During the years ended December 31, 1998 and 1997, approximately 19% of the
Company's Software Protection Products revenue was subject to currency
fluctuations. Software Protection Products revenue in the future is expected to
continue to be affected by foreign currency rate fluctuations.
 
                                       11
<PAGE>   13
 
     Information Security Products revenue for the year ended December 31, 1998
increased 48% to $50,236,000, as compared with 1997. The revenue growth was
primarily due to increased shipments of secure network communication products.
 
     Internet Security Products revenue for the year ended December 31, 1998
increased 661% to $1,690,000 as compared with 1997. The revenue growth was
primarily due to the adoption of Hewlett Packard and Watchguard as OEM's for the
Company's Internet products.
 
     Gross profit for Software Protection Products for the year ended December
31, 1998 was 71% of revenues which was consistent with the year ended December
31, 1997. There can be no assurance that the Company will improve or maintain
the level of gross profit percentage it experienced during the year ended
December 31, 1998.
 
     Gross profit from Information Security Products for the year ended December
31, 1998 was 22% of revenues compared with 20% of revenues for the year ended
December 31, 1997. The increase in gross profit was due to the change in mix
from less profitable research and development contracts to more profitable
product contracts.
 
     Gross profit from Internet Security Products for the year ended December
31, 1998 was 54% of revenues compared with 51% of revenues for the year ended
December 31, 1997. The increase in gross profit was due to the decrease in
overall unit costs as a result of the increase in total sales.
 
     Selling, general and administrative expenses for the year ended December
31, 1998 were 24% of revenues compared with 23% of revenues for the year ended
December 31, 1997. Selling, general and administrative expenses for the year
ended December 31, 1998 increased by $4,642,000 as compared with 1997. This
increase was primarily due to additional staff and higher marketing expenses for
new product introductions in software protection and internet security products
and subsidiary reorganization costs which were primarily related to the
Company's efforts to lower its future effective tax rate.
 
     Research and development expenses for both years ended December 31, 1998
and 1997 were 9% of revenues. Current research and development activities are
primarily focused on additional ASIC development for future products and the
adaptation of the Company's existing products to additional software operating
environments and computer platforms.
 
     Goodwill amortization for the year ended December 31, 1998 increased
$1,002,000 as compared with 1997 due to an increase in goodwill resulting from
the 1998 Wyatt acquisition.
 
     In the fourth quarter of 1998, the Company determined that the aggregate
estimated future undiscounted operating cash flows of Quantum Manufacturing
Technologies, Inc. ("QMT"), a majority owned subsidiary, were less than the
carrying amount of long-lived assets related to QMT. Based on its evaluation,
the Company determined the assets with a carrying value of $6,105,000 were
impaired and wrote them down by $3,942,000 to the estimated fair value. Fair
value was based on estimated discounted future operating cash flows of QMT. For
the year ended December 31, 1998, the Company recognized a minority interest
share in the loss of QMT.
 
     During the year ended December 31, 1998, the Company wrote-off $1,500,000
of in-process research and development acquired in the Wyatt River Software,
Inc. ("Wyatt") acquisition.
 
     Interest income for the year ended December 31, 1998 decreased by 14% to
$1,375,000, as compared with 1997, primarily due to lower average cash and cash
equivalent balances during 1998.
 
     During the first quarter of 1998, the Company wrote-off a $1,320,000
investment which was determined to be fully impaired. This amount has been
included in other income (expense), net for the year ended December 31, 1998.
 
     During the year ended December 31, 1998, the Company incurred foreign
currency losses of $90,000, primarily due to dollar denominated deposit accounts
maintained in Europe. During the year ended December 31, 1997, the Company
recognized foreign currency losses of $167,000, also primarily due to dollar
denominated deposit accounts maintained in Europe. Such foreign currency gains
and losses result from the
 
                                       12
<PAGE>   14
 
movement in the value of the U.S. dollar against the functional currencies used
by the Company's foreign subsidiaries.
 
     The effective tax rate was 72% for the year ended December 31, 1998
compared to 41% for the year ended December 31, 1997. The effective tax rate for
1998 was negatively affected due to non-deductibility of the charges related to
acquired in-process research and development, the non-deductibility of the
write-off of a long-term investment, and asset impairment charges related to
QMT. Excluding the effect of these charges, the effective tax rate was 43% for
the twelve months ended December 31, 1998.
 
1997 COMPARED WITH 1996
 
     Software Protection Products revenue for the year ended December 31, 1997
increased 5% to $60,125,000 as compared with 1996. The revenue growth was
primarily due to increased unit sales in Asia Pacific and North American
markets. Revenues in Asia Pacific grew by 37%. Revenues in European markets were
consistent in 1997 and 1996. The average selling price per product for the year
ended December 31, 1997 decreased approximately 7% from the year ended December
31, 1996.
 
     During the year ended December 31, 1997, approximately 19% of the Company's
Software Protection Products revenue was subject to currency fluctuations, down
from 22% in 1996. Software Protection Products revenue in the future is expected
to continue to be affected by foreign currency rate fluctuations.
 
     Information Security Products revenue for the year ended December 31, 1997
increased 40% to $33,894,000, as compared with 1996. The revenue growth was
primarily due to increased shipments of secure network communication products.
 
     Internet Security Products revenue for the year ended December 31, 1997
increased 616% to $222,000, as compared with 1996. Revenues in 1996 comprised of
approximately two months' sales, with the establishment of this segment in
October 1996.
 
     Gross profit for Software Protection Products for the year ended December
31, 1997 was 71% of revenue compared with 70% for the year ended December 31,
1996. The increase in gross profit was due to improvements in manufacturing
efficiencies.
 
     Gross profit from Information Security Products for the year ended December
31, 1997 was 20% of revenues compared with 18% of revenues for the year ended
December 31, 1996. The increase in gross profit was due to the change in mix
from less profitable research and development contracts to more profitable
product contracts.
 
     Gross profit from Internet Security Products for the year ended December
31, 1997 was 51% of revenues.
 
     Selling, general and administrative expenses for the years ended December
31, 1997 and 1996 were 23% and 24% of revenues, respectively. Selling, general
and administrative expenses for the year ended December 31, 1997 increased by
$2,223,000 as compared with 1996. This increase was primarily due to additional
staff and higher marketing expenses for new product introductions in software
protection and information security products.
 
     Research and development expenses were 9% and 8% of revenues for each of
the years ended December 31, 1997 and 1996, respectively. Current research and
development activities are focused on additional ASIC development for future
products and the adaptation of the Company's existing products to additional
software operating environments and computer platforms.
 
     Goodwill amortization for the year ended December 31, 1997 was consistent
with 1996.
 
     Interest income for the year ended December 31, 1997 increased by 6% to
$1,605,000, as compared with 1996, primarily due to higher average cash and cash
equivalent balances during 1997.
 
     During the year ended December 31, 1997, the Company incurred foreign
currency losses of $167,000, primarily due to dollar denominated deposit
accounts maintained in Europe. During the year ended December 31, 1996, the
Company recognized foreign currency gains of $270,000, also primarily due to
dollar
 
                                       13
<PAGE>   15
 
denominated deposit accounts maintained in Europe. Such foreign currency gains
and losses result from the movement in the value of the U.S. dollar against the
functional currencies used by the Company's foreign subsidiaries.
 
     For the year ended December 31, 1997, the Company recognized a minority
interest share in the loss of QMT, a majority owned subsidiary of the Company.
 
     The effective tax rate was 41% for the year ended December 31, 1997
compared with 41.4% for the year ended December 31, 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's principal sources of operating funds have been from
operations and proceeds from sales of the Company's equity securities. The
Company's cash flow from operations during 1998, 1997 and 1996 was $12,269,000,
$12,948,000, and $12,262,000, respectively. The impact of a higher accounts
receivable balance for 1998 was offset by the asset impairment charge related to
QMT. For 1997 the impact of higher accrued liabilities was offset by an increase
in accounts receivable and inventory. For 1996 the impact of higher inventory
and accounts receivable balances were partially offset by the increase in
accrued liabilities and the decrease in unbilled costs and fees.
 
     Net cash used in investing activities for 1998 increased from 1997 due to
the acquisition of Wyatt and increased proceeds from the sales of marketable
securities during 1997. Net cash used in investing activities for 1997 increased
from 1996 due to the asset purchase from AlliedSignal and increased proceeds
from the sales of marketable securities.
 
     The Company intends to use its capital resources to expand its product
lines and for possible acquisitions of additional products and technologies. The
Company has no significant capital commitments or requirements at this time.
 
     The Company's subsidiaries in France carry approximately $11,500,000
million in interest earning deposits which may result in foreign exchange gains
or losses due to the fact that the functional currency in those subsidiaries is
not the U.S. dollar.
 
     Management believes that the effect of inflation on the business of the
Company for the past three years has been minimal.
 
     The Company believes that its current working capital of $59,763,000 and
anticipated working capital to be generated by future operations will be
sufficient to support the Company's working capital requirements through at
least December 31, 1999.
 
IMPACT OF YEAR 2000
 
     The Year 2000 issue exists because many computer systems, applications and
embedded microprocessors use two rather than four digits to define the
applicable year. Because this issue has the potential to disrupt the Company's
business operations, a comprehensive, company wide, Year 2000 program was
initiated to identify and remediate the potential issues surrounding the Year
2000 problem. The Year 2000 program addresses the problems that may arise in
computer technologies, which include both information technology ("IT") and
non-IT systems, and those Year 2000 issues related to third parties with which
the Company has a material relationship.
 
     One of the Company's first priorities was communicating to customers the
Year 2000 compliance status of the Company's products. To aid in this effort,
the Company developed an Internet web site that describes the type of
date-related processing in the products (if any), which products have been
tested for Year 2000 compliance, and the results of that testing. The site is
updated as new products and new information become available. In addition, the
Company's Year 2000 program includes a process for responding to customer
inquiries and for handling special customer requests.
 
                                       14
<PAGE>   16
 
     For the purposes of process management and progress reporting, the Year
2000 program activities are divided into 5 phases, some of which are being
conducted concurrently:
 
     AWARENESS -- This phase included definition of the systems, project and
scope, overall approach, determination of teams, briefings, and setting of a
compliance standard. The awareness phase has been completed.
 
     ASSESSMENT -- The assessment phase included the development of a
comprehensive inventory and assessment of the criticality of systems,
prioritization, determination of resource requirements, and estimation of costs.
General decisions were made about modification, re-engineering, replacement or
removal of systems and business partners. The validation approach and schedule
was determined.
 
     RENOVATION -- The renovation phase includes the re-engineering,
replacement, or retirement of systems. Test plans are developed for revised and
replaced systems.
 
     VALIDATION -- Tests are run in an isolated test environment to determine
functionality.
 
     IMPLEMENTATION -- In this phase, the implementation dates are scheduled,
and the need for parallel processing, back-up, recovery and contingency plans
are determined. Following implementation, there is a review for effectiveness.
 
     STATE OF READINESS
 
  IT and Non-IT Systems
 
     The Company's IT systems principally consist of business information
systems (such as shared computers and associated business application software)
and infrastructure (such as personal computers, operating systems, networks and
devices like switches and routers). As of March, 1999, the inventory of these
systems is complete and the assessment and validation of systems deemed
"business critical" is more than 75% complete. The implementation of upgraded,
renovated or replacement business critical systems is scheduled to be completed
by June, 1999. All of the remaining, non-critical, IT systems are being
evaluated on the basis of tests (if deemed necessary), and manufacturer
statements regarding Year 2000 compliance. The Company expects that the
assessment and, when required, renovation or replacement of all IT systems will
be completed in time to ensure no significant adverse effect on business
operations.
 
     Non-IT systems are those business tools that may contain embedded
microprocessors, such as elevators, phones, security systems and climate control
systems. The inventory of these items is completed and the vendors have been
contacted to obtain Year 2000 compliance information. The decision to remediate,
replace or otherwise address equipment that poses a material Year 2000 impact is
based primarily upon analysis of the information received from the manufacturer.
To date, more than 75% of the manufacturers have responded and indicated that no
Year 2000 related problems will be experienced with the equipment as provided.
The Company anticipates completion, in all material respects, of the non-IT
infrastructure portion of its program by June 1999.
 
  External Relationships
 
     The Company also faces a potential risk should one or more of its principal
suppliers, service providers or other parties with whom the Company has a
material business relationship suffer a Year 2000 related problem. A
comprehensive inventory of business partners was made, and the Company has
initiated contact with them in an effort to determine their state of readiness.
Assessment of the risk posed to the Company will be based on the level of
criticality to the Company (the potential business impact, available
alternatives and resources required to replace) and the response received from
each party. A cut-off date has been assigned to each business critical third
party by which time that company must be assessed as "Year 2000 Ready" or a
contingency plan will be implemented to ensure the Company will suffer no
material impact to its ability to provide products and services to customers.
Approximately 1300 companies were contacted, about 100 of which are considered
business critical, and to date approximately 40% of the total have responded.
The Company anticipates that this evaluation will be ongoing through 1999.
 
                                       15

     CONTINGENCY PLANNING
 
     The Company recognizes the need for contingency planning in those areas
where it is known, or is reasonably likely that an event or an uncertainty will
create a Year 2000 system-related failure with a significant negative impact on
its business operations. The Company has identified the date by which each
business critical IT system, non-IT system, and business partner must be
validated for Year 2000 readiness, and by which a contingency plan must be
implemented to ensure uninterrupted business operations. Contingency planning is
expected to be completed for each of these systems no later than that date, and
in all cases, no later than October 1999.
 
     COSTS
 
     The Company has incurred approximately $500,000 as of December 31, 1998, to
address its Year 2000 issues. The Company presently estimates that the total
cost of addressing its Year 2000 issues will be approximately $750,000 to
$1,000,000. This estimate was derived utilizing numerous assumptions. First, the
current staff is adequate to finish the project. Second, the product is already
Year 2000 compliant. Next, to the best of its knowledge, the Company estimates
that approximately half of the work is already done and that no system changes
are anticipated. However, there can be no guarantee that these assumptions are
accurate, and actual results could differ materially from those anticipated.
 
     RISKS
 
     The Company's Year 2000 program is designed to discover and remediate or
reduce the risks associated with the Year 2000 issue. The Company anticipates
that it will complete the remediation, risk assessment and contingency planning
for its internal IT and non-IT systems, and immediate, business critical
third-party providers. The most reasonably likely worst case scenario involves
the disruption of operations caused by the Company's reliance upon a network of
critical suppliers (such as utility, telecommunications, and transportation
service providers) whose own systems unexpectedly fail. While such failures
could directly or indirectly affect important operations of the Company, in a
significant manner, the Company does not have sufficient information about or
control over its third party suppliers to determine either the likelihood or
potential costs of these failures. Accordingly, the costs and results of the
Company's Year 2000 program and the extent of the impact on operations could
materially differ from the Company's expectations.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
     Market risk generally represents the risk that losses may occur in the
values of financial instruments as a result of movements in interest rates,
foreign currency exchange rates and commodity prices. The Company is exposed to
changes in financial market conditions in the normal course of its business due
to its use of certain financial instruments as well as transacting in various
foreign currencies and translation of its foreign subsidiaries financial
statements to the U.S. dollar.
 
INTEREST RATE RISK
 
     At December 31, 1998 and 1997, the Company's cash equivalents and
short-term investments included approximately $6.5 million and $6.8 million,
respectively, of fixed income securities. These securities are subject to
interest rate risk and may decline in value when interest rates change.
Approximately 87% of the December 31, 1998 fixed income securities portfolio
will mature during 1999 and approximately 44% of the December 31, 1997 portfolio
matured during 1998. An adverse change of 10% in interest rates would have an
immaterial effect on the fair value of these securities. These investments do
not represent a material market risk to the Company. The Company places
substantially all of its interest bearing investments with major financial
institutions and by policy limits the amount of credit exposure to any one
financial institution. Additionally, the Company does not hold or issue
financial instruments for trading, profit or speculative purposes.
 
                                       16
<PAGE>   18
 
EQUITY PRICE RISK
 
     The Company holds investments in various available-for-sale equity
securities which are subject to price risk. The fair value of such investments,
as of December 31, 1998 and 1997 was approximately $2 million, and $3 million,
respectively. The potential change in the fair value of these investments,
assuming a 10% decline in prices would be approximately $200,000, and $300,000
for 1998 and 1997, respectively.
 
FOREIGN EXCHANGE RATE RISK
 
     The Company operates internationally and has adopted local currencies as
the functional currencies for its foreign subsidiaries because their principal
economic activities are most closely tied to the respective local currencies.
This exposes the Company to market risk from changes in foreign exchange rates
to the extent that transactions are not denominated in the U.S. dollar. In
consolidation, the Company converts the accounts of its foreign subsidiaries
from the functional currency to the U.S. dollar. As a result the Company faces
the risk that the foreign currencies will have declined in value as compared to
the U.S. dollar, resulting in a foreign currency translation loss. Assuming an
adverse 10% foreign exchange rate fluctuation, the Company would have
experienced translation losses of approximately $2 million for both 1998 and
1997.
 
     The Company's earnings are affected by fluctuations in the value of the
U.S. dollar as compared to foreign currencies as a result of the sales of its
products in foreign markets. Assuming an adverse 10% foreign exchange rate
fluctuation, the Company would have had a decrease in net income of
approximately $200,000 for both the years ended December 31, 1998 and 1997. This
calculation assumes that each exchange rate would change in the same direction
relative to the U.S. dollar. In addition, to the direct effects of changes in
exchange rates, which are a changed dollar value of the resulting sales, changes
in exchange rates also affect the volume of sales or the foreign currency sales
price as competitors' products become more or less attractive. The Company's
sensitivity analysis of the effects of changes in foreign currency exchange
rates does not factor in a potential change in sales levels or local currency
prices.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Rainbow Technologies, Inc.
 
     We have audited the accompanying consolidated balance sheets of Rainbow
Technologies, Inc. as of December 31, 1998 and 1997, and the related
consolidated statements of income, shareholders' equity, and cash flows for each
of the three years in the period ended December 31, 1998. Our audits also
included the financial statement schedule listed in the Index at Item 14(a).
These financial statements and the financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and the schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Rainbow
Technologies, Inc. at December 31, 1998 and 1997, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1998, in conformity with generally accepted accounting
principles. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1998
 
 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
GENERAL
 
     Rainbow Technologies, Inc. (the Company) develops, manufactures, programs
and markets products which prevent the unauthorized use of intellectual
property, including software programs; develops and manufactures information
security products for satellite communications; and develops and manufactures
internet security products to provide privacy and security for network
communications. The accompanying financial statements consolidate the accounts
of the Company and its wholly-owned subsidiaries. All significant intercompany
balances and transactions have been eliminated. Certain amounts previously
reported have been reclassified to conform with the 1998 presentation. Share
amounts for all years presented have been adjusted to reflect the impact of a
3-for-2 stock split effective July 1, 1998.
 
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 amounts reported in the accompanying financial
statements. Actual results could differ from those estimates. Significant
estimates made in preparing these financial statements include the allowance for
doubtful accounts, the reserve for inventory obsolescence, accrued warranty
costs, the allowance for deferred tax assets, total estimated contract costs
associated with billed and unbilled contract revenues, and future operating cash
flows used in the long-lived assets impairment analysis of Quantum Manufacturing
Technologies, Inc. (QMT), one of the Company's subsidiaries.
 
CASH EQUIVALENTS
 
     The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.
 
MARKETABLE SECURITIES
 
     All investment securities are considered to be available-for-sale and are
carried at fair value. Management determines classification at the time of
purchase and re-evaluates its appropriateness at each balance sheet date. The
Company's marketable securities consist of tax-exempt and other debt instruments
that bear interest at variable rates. As of December 31, 1998 gross unrealized
losses were $226,000 while gross unrealized losses were $128,000 as of December
31, 1997. There were no material realized gains or losses recognized for the
years ended December 31, 1998, 1997 and 1996. The cost of securities sold is
based on the specific identification method. The Company's portfolio of
marketable debt securities at December 31, 1998 matures as follows: 87% in 1999,
0% in 2000 - 2004, and 13% thereafter.
 
SOFTWARE DEVELOPMENT COSTS
 
     Statement of Financial Accounting Standards No. 86, "Accounting for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed," requires
capitalization of certain software development costs subsequent to the
establishment of technological feasibility. Based on the Company's product
development process, technological feasibility is established upon completion of
a working model. Amortization of capitalized software development costs
commences when the products are available for general release to customers and
are determined using the straight line method over the expected useful lives of
the respective products.
 
     At December 31, 1998 and 1997, the Company had capitalized computer
software costs of $2,026,000 and $1,844,000, respectively. Amortization of
computer software development costs for the years ended

                               DECEMBER 31, 1998
 
December 31, 1998, 1997 and 1996 amounted to $233,000, $173,000 and $44,000,
respectively. During 1998, 1997 and 1996, the Company wrote-off $784,000,
$242,000 and $273,000 respectively, of previously capitalized computer software
development costs which were determined to be obsolete.
 
INVENTORIES
 
     Inventoried costs relating to long-term contracts are stated at the actual
production cost, including pro-rata allocations of factory overhead and general
and administrative costs incurred to date reduced by amounts identified with
revenue recognized on units delivered. The costs attributed to units delivered
under such long-term contracts are based on the estimated average cost of all
units expected to be produced.
 
     Inventories other than inventoried costs relating to long-term contracts
are stated at the lower of cost (first-in, first-out basis) or market.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Additions to property, plant, equipment and leasehold improvements are
recorded at cost and depreciated on the straight-line method over their
estimated useful lives as follows:

Buildings.............................................       31 years
Furniture.............................................   5 to 7 years
Equipment.............................................   3 to 7 years
Leasehold improvements................................  Term of lease
</TABLE>
 
INTANGIBLE ASSETS
 
     Intangible assets consisting of goodwill, product licenses and patents are
amortized using the straight-line method over seven to ten years. Goodwill
represents the excess of purchase price over the estimated fair value of assets
acquired.
 
LONG-LIVED ASSETS
 
     In accordance with Statement of Financial Accounting Standards No. 121
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of" (FAS 121), the Company records impairment losses on long-lived
assets used in operations when events and circumstances indicate that the assets
might be impaired and the undiscounted cash flows estimated to be generated by
those assets are less than the carrying amounts of those assets.
 
REVENUE RECOGNITION
 
  Software Protection Products and Internet Security Products
 
     The Company recognizes revenues from Software Protection Product sales at
the time of shipment. Provision is currently made for estimated product returns
which may occur under programs the Company has with certain of its distributors.
 
  Information Security Products
 
     Catalog product revenues and revenues under certain fixed-price contracts
calling for delivery of a specified number of units are recognized as deliveries
are made. Revenues under cost-reimbursement contracts are recognized as costs
are incurred and include estimated earned fees in the proportion that costs
incurred to date bear to total estimated costs. Certain contracts are awarded on
a fixed-price incentive fee basis. Incentive fees on such contracts are
considered when estimating revenues and profit rates and are

                               DECEMBER 31, 1998
 
recognized when the amounts can reasonably be determined. The costs attributed
to units delivered under fixed-price contracts are based on the estimated
average cost per unit at contract completion. Profits expected to be realized on
long-term contracts are based on total revenues and estimated costs at
completion. Revisions to contract profits are recorded in the accounting period
in which the revisions are made. Estimated losses on contracts are recorded when
identified. For research and development and other cost-plus-fee type contracts,
the Company recognizes contract earnings using the percentage-of-completion
method. The estimated contract revenues are recognized based on
percentage-of-completion as determined by the cost-to-cost basis whereby
revenues are recognized ratably as contract costs are incurred.
 
  Ion Beam Surface Treatment
 
     The Company recognizes revenues from ion beam surface treatments at the
time services are provided.
 
WARRANTY
 
     The Company generally warrants its products for one year. An estimate of
the amount required to cover warranty expense on products sold is charged
against income at the time of sale.
 
ADVERTISING
 
     The Company expenses the costs of advertising as incurred. Advertising
expense was $2,857,000, $2,601,000 and $2,221,000 for 1998, 1997, and 1996,
respectively.
 
RESEARCH AND DEVELOPMENT
 
     Expenditures for research and development are expensed as incurred.
 
INCOME TAXES
 
     Deferred taxes are provided for items recognized in different periods for
financial and tax reporting purposes in accordance with Financial Accounting
Standards Board Statement No. 109, "Accounting For Income Taxes."
 
FOREIGN CURRENCY
 
     Balance sheet accounts denominated in foreign currency are translated at
exchange rates as of the date of the balance sheet and income statement accounts
are translated at average exchange rates for the period. Translation gains and
losses are accumulated as a separate component of Accumulated Other
Comprehensive Income within Shareholders' Equity. The Company has adopted local
currencies as the functional currencies for its subsidiaries because their
principal economic activities are most closely tied to the respective local
currencies.
 
     The Company may enter into foreign exchange contracts as a hedge against
foreign currency denominated receivables. It does not engage in currency
speculation. Foreign currency transaction gains and losses are included in
current earnings. There were no foreign exchange contracts at December 31, 1998
or 1997.
 
STOCK OPTION PLANS
 
     The Company applies the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (FAS No. 123) and accordingly, is accounting for its stock-based
compensation plans under Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees" (APB 25) and related interpretations. Under APB
25, because the exercise price of the

Company's employee stock options equals the market price of the underlying stock
on the date of grant, no compensation expense is recognized.
 
EARNINGS PER SHARE
 
     Basic earnings per share is computed by dividing income available to common
shareholders by the weighted-average number of common shares outstanding for the
period. Diluted earnings per share reflects the assumed conversion of all
dilutive securities.
 
CONCENTRATIONS OF BUSINESS AND CREDIT RISK
 
     Financial instruments which potentially subject the Company to credit risk
consist principally of trade receivables and interest bearing investments. The
Company performs on-going credit evaluations of its customers and generally does
not require collateral. The Company maintains adequate reserves for potential
losses and such losses, which have historically been minimal, have been included
in management's estimates. The Company places substantially all of its interest
bearing investments with major financial institutions and, by policy, limits the
amount of credit exposure to any one financial institution.
 
     The Company sells the majority of its Software Protection Products to
software developers and wholesale distributors throughout North America, Europe
and Asia Pacific. The majority of the Company's Information Security Products
are sold to the U.S. Government (Note 3). The U.S. Government accounted for over
67%, 52%, and 65% of contract revenues in 1998, 1997, and 1996, respectively. In
addition, approximately 67% and 99% of contract accounts receivable and 73% and
86% of unbilled costs and fees at December 31, 1998 and 1997, respectively, were
related to the U.S. Government.
 
COMPREHENSIVE INCOME
 
     Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" (FAS 130). FAS
130 establishes new rules for the reporting and display of comprehensive income
and its components; however, the adoption of FAS 130 had no impact on the
Company's net income or shareholders' equity. FAS 130 requires unrealized gains
or losses on the Company's available-for-sale securities and foreign currency
translation adjustments, which prior to adoption were reported separately in
shareholders' equity, to be included in other comprehensive income. All periods
presented have been reclassified to conform to the requirements of FAS 130.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     The Accounting Standards Executive Committee (AcSEC) issued SOP 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use", during 1998. The objective of the SOP is to provide guidance that
specifically addresses the accounting for the costs related to developing,
obtaining, modifying and/or implementing internal use software. The SOP requires
that companies capitalize qualifying costs incurred during the application
development stage. Additionally, the SOP requires companies to evaluate
capitalized software costs for impairment in accordance with FAS121.
 
     SOP 98-1 is effective for financial statements for fiscal years beginning
after December 15, 1998 and should be applied prospectively to all costs
incurred in connection with internal use software development projects in those
fiscal years, including costs incurred subsequent to adopting the SOP on
projects that commenced in earlier years. SOP 98-1 does not require any new
disclosures, however, information related to internal use software may be
required by other accounting literature. The Company will adopt SOP 98-1 in
fiscal 1999 and does not believe that adoption will have a material impact to
its financial statements.

 2. ACQUISITIONS
 
     On February 26, 1998, the Company completed the acquisition of Wyatt River
Software, Inc. (Wyatt). Wyatt develops, manufactures, and markets network
license management software. The total transaction value was $9 million,
including $3.9 million paid in cash to Wyatt stockholders and $5.1 million in
assumed liabilities. The Company may be required to pay Wyatt shareholders an
additional sum of up to $2 million based upon sales of the Wyatt technology
through June 30, 1999. This acquisition has been accounted for under the
purchase method of accounting. The purchase price has been allocated based upon
estimated fair values at the date of acquisition. Approximately $1.5 million of
the purchase price was written off as in-process research and development at the
acquisition date, approximately $2.7 million was allocated to developed
software, and the remaining $4.8 million was allocated to goodwill and other
intangibles. The goodwill and other intangibles are being amortized on a
straight-line basis over five years. At December 31, 1998 the Company wrote-off
developed software related to the Wyatt acquisition which had a net book value
of $427,000. This amount has been included in research and development expense
for the year ended December 31, 1998.
 
     On March 6, 1998, the Company entered into an agreement to purchase certain
assets from Elan Computer Group, Inc. (Elan) for $800,000. The assets included
Elan's license manager software technology, which the Company had previously
licensed from Elan, and Elan's end-user maintenance and support relationships.
In connection with the transaction, the Company entered into a Litigation
Cooperation Agreement with Elan in connection with a patent infringement lawsuit
entitled Globetrotter Software, Inc. vs. Elan Computer Group, Inc. No. 97-4176CW
which is currently pending in the United States District court for the Northern
District of California. The action claims that the Elan technology infringes
upon patents owned by Globetrotter. The lawsuit is deemed to include any and all
claims made now or in the future by Globetrotter Software, Inc. The Company does
not expect that this matter will have a material adverse effect on its financial
position or results of operations. Prior to the asset purchase agreement with
Elan, the Company had an investment in Elan of $1.3 million. The Company owned
less than 20% of Elan's stock and accounted for the investment under the cost
method. During the first quarter of 1998 the Company wrote-off its investment in
Elan, as it was determined that the Company's original investment was fully
impaired. The write-off is included in other income (expense), net in the income
statement for the year ended December 31, 1998.
 
     In October 1997, the Company acquired certain assets from AlliedSignal,
Inc. for approximately $7 million in cash comprising AlliedSignal's "KIV-7"
information security product line. The Company is the sole supplier of KIV-7 to
various agencies of the U.S. Government. Simultaneous with the closing of the
asset purchase transaction, the Company entered into a manufacturing and
development agreement with AlliedSignal whereby Allied-Signal will continue to
manufacture current KIV-7 products for the Company, and will complete the
development of an enhanced version of the KIV-7 product. In September 1998,
Raytheon Systems Company acquired the division of Allied-Signal which
manufactured the KIV-7 product. As a result, Raytheon has assumed the
obligations to manufacture the KIV-7 product and to complete the enhanced
version of the product.
 
     In May 1997, the Company completed its obligations pursuant to a Stock
Purchase Agreement entered into in March 1996 which resulted in the Company
investing approximately $6 million in QMT. As of December 31, 1998, the Company
owns a majority interest in QMT and accordingly recognizes a minority interest
share in its losses. QMT, located in Albuquerque, New Mexico, owns an exclusive
worldwide license from Sandia National Laboratories for the commercial use and
exploitation of a patented pulsed power ion beam materials treatment technology
known as "IBEST". In the fourth quarter of 1998, the Company determined that the
aggregate estimated future undiscounted operating cash flows of QMT, one of its
subsidiaries, were less than the carrying amount of long-lived assets related to
QMT. Based on its evaluation,

                               DECEMBER 31, 1998
 
the Company determined the assets with a carrying value of $6.1 million were
impaired and wrote them down by $3,942,000 to the estimated fair value. Fair
value was based on estimated discounted future operating cash flows of QMT. The
FAS 121 charge had no impact on the Company's 1998 cash flows or its ability to
generate cash flows in the future. As a result of the FAS 121 charges,
depreciation and amortization expense related to those assets will decrease in
future periods.
 
     The results of the acquired operations are included in the consolidated
statements of income from the respective dates of acquisition. Pro forma income
statement information for 1998 and 1997 related to the above acquisitions has
not been presented because the respective acquisitions are not significant
enough to require such presentation.
 
     On October 4, 1996, the Company acquired Software Security, Inc. (SSI) in a
merger transaction resulting in SSI becoming a wholly-owned subsidiary of
Rainbow. SSI, which was headquartered in Stamford, Connecticut, designs,
develops and manufactures software security products to prevent the unauthorized
use of intellectual property. These products are sold in the U.S. and Europe.
Shareholders of SSI received 0.525 shares of Company common stock for each share
of issued and outstanding SSI common stock. Accordingly, the Company issued
504,767 shares of its common stock to SSI shareholders in exchange for all
outstanding SSI shares. In addition, 6,549 shares of Rainbow common stock were
reserved for issuance upon the exercise of assumed SSI options. The merger was
accounted for as a pooling-of-interests. Expenses associated with the merger of
approximately $191,000 were included in the consolidated results of operations
for the year ended December 31, 1996. There were no significant intercompany
transactions between Rainbow and SSI during any period presented.
 
 3. GOVERNMENT CONTRACTS
 
     The Company is both a prime contractor and subcontractor under fixed-price
and cost reimbursement contracts with the U.S. Government (Government). At the
commencement of each contract or contract modification, the Company submits
pricing proposals to the Government to establish indirect cost rates applicable
to such contracts. These rates, after audit and approval by the Government, are
used to settle costs on contracts completed during the previous fiscal year.
 
     To facilitate interim billings during the performance of its contracts, the
Company establishes provisional billing rates, which are used in recognizing
contract revenue and contract accounts receivable. These provisional billing
rates are adjusted to actual at year-end and are subject to adjustment after
Government audit.
 
     The Company has unbilled costs and fees of $2,740,000 and $1,782,000 at
December 31, 1998 and 1997, respectively. Based on the Company's experience with
similar contracts in recent years, the unbilled costs and fees at December 31,
1998 are expected to be collected within one year.

related to the Company's efforts to lower its future effective tax rate.
 
 7. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The fair values presented are estimates of the fair value of the financial
instruments at a specific point in time using available market information and
appropriate valuation methodologies. These estimates are subjective in nature
and involve uncertainties and significant judgment in the interpretation of
current market data. Therefore, the fair values presented are not necessarily
indicative of amounts the Company could realize or settle currently. The Company
does not intend to dispose of or liquidate such instruments prior to maturity.
 
     The carrying values and estimated fair values of the Company's financial
instruments are as follows for the years ended December 31:

 9. STOCK OPTION PLANS
 
     In August 1987, the Board of Directors adopted an incentive stock option
plan and a non-qualified stock option plan under which options could be granted
to purchase up to an aggregate of 700,000 shares of the Company's common stock.
The exercise price for options granted under these plans could not be less than
100% of the fair market value of the common stock on the date of grant. Options
become exercisable and expire at the discretion of the Board of Directors,
although the plans specify that no options shall be exercisable prior to 12
months from the date of grant and all options expire five years from the date of
grant.
 
     On April 12, 1990, the Board of Directors of the Company terminated the
1987 plans and approved the Company's 1990 Stock Option Plan under which
non-statutory or incentive stock options may be granted to key employees and
individuals who provide services to the Company. Up to an aggregate of 450,000
shares of the Company's common stock were originally authorized for issuance.
Options become exercisable and expire at the discretion of the Board of
Directors, although the plan specifies that no options shall be exercisable
prior to 12 months from the date of grant and all options expire ten years from
the date of grant. In June 1993, the shareholders approved an amendment to the
Company's Restated 1990 Stock Option Plan authorizing the issuance of an
additional 450,000 shares of common stock. In May 1995 an additional increase of
750,000 was approved and in June 1997 an additional increase of 750,000 was
approved. As of December 31, 1998 the total number of shares available for grant
under the existing stock option plans was 37,000.

</TABLE>
 
     The weighted average remaining contractual life of stock options
outstanding at December 31, 1998 and 1997 was 7.6 years and 8.0 years,
respectively.
 
     Pro forma information regarding net income and earnings per share is
required by FAS 123 and has been determined as if the Company had accounted for
its employee stock options under the fair value method of that Statement. The
fair value for the options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted average
assumptions for 1998, 1997 and 1996: risk free interest rate of 4.8% for 1998,
5.7% for 1997 and 6.3% for 1996; dividend yield of 0% for 1998, 1997 and 1996;
volatility factor of the expected market price of the Company's common stock of
0.42 for 1998, 0.39 for 1997 and 0.38 for 1996; and a weighted-average life of
the option of 4.0 years for 1998, 1997 and 1996.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

                               DECEMBER 31, 1998
 
     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows:
 
<TABLE>
<CAPTION>
                                               1998         1997          1996
                                            ----------   -----------   ----------

Pro forma net income......................  $1,305,000   $10,120,000   $9,840,000
Pro forma earnings per share:
  Basic...................................  $      .11   $       .87   $      .85
  Diluted.................................         .11           .85          .83
</TABLE>
 
     The results above are not likely to be representative of the effects of
applying SFAS 123 on reported net income or loss for future years as these
amounts reflect the expense for only one to three years vesting.
 
10. SHAREHOLDER'S RIGHTS PLAN
 
     In July 1997, the Board of Directors of the Company adopted a Shareholder's
Rights Plan. In so doing, the Board of Directors declared a dividend of one
right (a "Right") for each outstanding share of the Company's Common Stock, as
of August 5, 1997 and subsequently with respect to each subsequent issuance of a
share of Common Stock. Following a "Distribution Date," each holder of a Right
is entitled to purchase, at a stated purchase price, shares of the Company's
Common Stock or other property having a value equal to two times the purchase
price. A Distribution Date will occur on the earlier of (i) the tenth day after
a public announcement that a person other than the Company or its affiliates has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more
of the outstanding Common Stock (such person thereby becoming an "Acquiring
Person"), or (ii) the tenth business day after the date of the commencement of,
or first public announcement of the intent of any person to commence, a tender
or exchange offer the consummation of which would result in such person becoming
an Acquiring Person. Following a Distribution Date, the Rights of an Acquiring
Person are null and void and not exercisable. Outstanding Rights are redeemable
by the Board of Directors at any time prior to a Distribution Date at a
redemption price of $0.01 per Right. The Rights will expire at the close of
business on August 5, 2002, unless earlier exercised by the holder or redeemed
by the Company.

1998, 1997 and 1996, Company contributions under both Plans totaled

14. INDUSTRY SEGMENTS
 
     Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 131, "Disclosures about Segments of an Enterprise and
Related Information" (FAS 131). FAS 131 superseded FASB Statement No. 14,
"Financial Reporting for Segments of a Business Enterprise". FAS 131 establishes
standards for the way that public business enterprises report information about
operating segments in annual financial statements and requires that those
enterprises report selected information about operating segments in interim
financial reports. FAS 131 also establishes standards for related disclosures
about products and services, geographic areas, and major customers. The adoption
of FAS 131 did not affect results of operations or financial position, but did
affect the disclosure of segment information.
 
     The Company operates in three industry segments. The first segment is the
development and sale of devices which protect data and software from
unauthorized use (Software Protection Products segment). The second segment is
the development and sale of information security products to provide privacy and
security for voice communication and data transmission (Information Security
Products segment). The third segment is the development and sale of services
which accelerate performance of security servers and virtual private networks
and services which provide access control to computer networks, Internet Web
sites and virtual private networks. Summaries of the Company's operations by
industry and geographic area are as follows:

         from the date RAINBOW informs NATIONAL of the extended date. The
         pricing below reflects no amortization.

         4.02     PRODUCTION PRICING
         Both PARTIES agree to the two scenarios described below, section 4.03
         and section 4.04. These scenarios apply relative to the final die size
         reached after the best design effort has been expended by NATIONAL. In
         addition, if NATIONAL determines during the design effort that it
         cannot attain either scenario 4.03 or scenario 4.04, NATIONAL may
         exercise its option under section 8.01 to terminate the DEVELOPMENT
         PROJECT and this AGREEMENT. In this case, any NRE paid to NATIONAL by
         RAINBOW will be refunded to RAINBOW.

   o up to 400k die per year                $____ per unit                   $____ per unit
   o up to 800k die per year                $____ per unit                   $____ per unit
</TABLE>

         NATIONAL agrees to renegotiate this pricing structure toward lower
         pricing based on a sliding scale in the event the die size achieved is
         smaller than 8,500 square mils. (e.g., the price would be $____ per
         unit for an 8000 square mils die if 800k units were delivered).

         The NRE under this scenario is agreed to be $334k per APPENDIX A.

               SCENARIO 4.04 PRODUCTION PRICE WITH SMALL DIE SIZE

The unit price for the RAINBOW ASIC units are as follows:

<TABLE>
<S>                                         <C>                             <C>

   o up to 200k units per year              $____ per unit
   o up to 400k units per year              $____ per unit

                                            WAFFLE-PACK DIE PRICE            TESTED-WAFER DIE PRICE
   o first 10k die                          $____ per unit                   $____ per unit
   o up to 200k die per year                $____ per unit                   $____ per unit
   o up to 400k die per year                $____ per unit                   $____ per unit
   o up to 800k die per year                $____ per unit                   $____ per unit
</TABLE>

         Under this scenario NATIONAL agrees to hold the pricing to the $____
         unit price at 800k quantities as a fixed pricing. In consideration
         thereof, RAINBOW agrees to pay the higher NRE of $____ per APPENDIX A.

         NATIONAL, at its option, may achieve a smaller die size than 7,500
         square mils, thus potentially improving its profitability, while
         holding to the fixed pricing with RAINBOW.

6.0      PRODUCTION ORDER DESCRIPTIONS

         6.01     PURCHASE ORDERS
         RAINBOW purchase orders are uncancelable and will explicitly state
         RAINBOW part numbers, NATIONAL part numbers, and RAINBOW ASIC
         descriptions and form of product delivery (i.e., packaged (SSOP),
         waffle pack, wafer, or membrane).


7.0      BUSINESS STRATEGY

         7.01     ESTABLISHING A SECOND MANUFACTURING LOCATION
         NATIONAL may, in its sole discretion, establish a second manufacturing
         location for RAINBOW ASIC production provided that it notifies RAINBOW
         in advance. RAINBOW will not be held accountable for the costs
         associated with starting a second manufacturing location.

         NATIONAL will perform the necessary tasks to establish the
         manufacturing capability at a second location if RAINBOW exercises this
         option by payment of ______________________ ($_________) to NATIONAL.

         The RAINBOW ASIC unit price shall not increase, regardless of where the
         manufacturing takes place. Pricing shall be renegotiated if more
         favorable cost structures are available at another site.

         7.02     DISCONTINUANCE OF MANUFACTURING
         If NATIONAL decides to discontinue manufacturing the RAINBOW ASIC,
         NATIONAL must notify RAINBOW in writing at least twelve (12) months in
         advance. NATIONAL will allow RAINBOW a "last buy" purchase order to
         cover the twelve (12) month period prior to the discontinue date.
         Furthermore, NATIONAL will provide reasonable assistance to transition
         the manufacturing of the product to an alternate supplier.

8.0      CANCELLATION
If either PARTY materially breaches this AGREEMENT, the other PARTY may, upon
thirty (30) days written notice of such breach or default, cancel its remaining
obligations under this AGREEMENT. In no event shall NATIONAL be liable for delay
in the rendering of services under this AGREEMENT due to causes beyond its
reasonable control, including by way of illustration, but not limited to, acts
of God, acts of civil or military authority, fire, or inability's due to causes
beyond NATIONAL's reasonable control to obtain necessary labor, materials,
facilities, or services. In the event of such a delay, the dates of performance
under this AGREEMENT shall be deferred for a period equal to the time lost by
reason of the delay. Notwithstanding such event or delay, RAINBOW may, if so
desires, exercise its rights under section 8.01. In the event that this
AGREEMENT is terminated, each PARTY shall return all PROPRIETARY INFORMATION and
works in progress received from the other PARTY.

         8.01     TERMINATION FOR CONVENIENCE OR FOR DEFAULT
         RAINBOW shall have the right, upon giving thirty (30) days written
         notice, to terminate the DEVELOPMENT PROJECT at any time. In the event
         of such termination, RAINBOW's total liability to NATIONAL shall be
         payment for the then current accumulated charges, including charges
         that were to be amortized and were expended.

         NATIONAL shall have the right, upon giving thirty (30) days written
         notice, to terminate the Development project. If this AGREEMENT is
         terminated by NATIONAL, then NATIONAL will return to RAINBOW any and
         all development charges that have already been paid at the time of
         termination. In such instance, NATIONAL will have no further liability.

         This AGREEMENT will terminate upon the termination of the DEVELOPMENT
         PROJECT. Section 3.0, however, will survive the termination of this
         AGREEMENT.

         inform the other PARTY at the time of disclosure of such information's
         proprietary nature, and confirm the same in writing to the receiving
         PARTY within thirty (30) days. The PARTIES agree to hold PROPRIETARY
         INFORMATION in confidence and to exert the same effort to prevent
         disclosure thereof as it would regarding its own proprietary
         information but in no less than a reasonable degree of care. The
         PARTIES agree to not disclose any PROPRIETARY INFORMATION without
         written authority. The obligations of this paragraph shall terminate
         with respect to any portion of the received PROPRIETARY INFORMATION:
         (a) known prior to receipt; (b) becoming known through no act or
         failure to act by either PARTY; or (c) furnished to third parties
         without restriction on disclosure; or (d) independently developed by
         the PARTY receiving the PROPRIETARY INFORMATION.

         3.02     OWNERSHIP OF INTELLECTUAL PROPERTY
         All INTELLECTUAL PROPERTY first conceived, discovered, developed, or
         acquired by one PARTY (alone or jointly with another party) outside the
         scope of the DEVELOPMENT PROJECT shall remain the sole and exclusive
         property of such PARTY.

         Except for the RAINBOW ASIC net list, any INTELLECTUAL PROPERTY first
         conceived, discovered, developed, or acquired solely by EM MARIN under
         the DEVELOPMENT PROJECT shall be the exclusive property of EM MARIN.
         Any RAINBOW ASIC net list shall be owned solely by RAINBOW.
         INTELLECTUAL PROPERTY first conceived, discovered, developed, or
         acquired solely by RAINBOW under the DEVELOPMENT PROJECT shall be the
         exclusive property of RAINBOW.

         INTELLECTUAL PROPERTY first conceived, discovered, developed, or
         acquired jointly, as those terms are used before the United States
         Patent Office, by both PARTIES under the DEVELOPMENT PROJECT shall be
         jointly owned by both PARTIES. Each PARTY shall have the right to
         exploit and licenses JOINT INTELLECTUAL PROPERTY without accounting to
         the other PARTY.

         In furtherance of the foregoing: (a) except for those licenses granted
         under section 3.03, no patent or software licenses of any kind are
         granted or implied under this AGREEMENT; and (b) no RAINBOW ASIC unit
         shall be transferred or sold to any third party without RAINBOW's
         signed and written permission.

         3.03     LICENSE GRANT
         Upon full payment of all development charges, RAINBOW will be granted a
         fully paid, perpetual, non-exclusive, license to:

         A.       use the EM MARIN DESIGN DATABASE (put into escrow according to
                  1.04.B.) to have RAINBOW ASIC units produced for the benefit
                  of RAINBOW by a third party vendor in the event that EM MARIN:
                  (i) breaches this AGREEMENT; (ii) is unwilling or unable to
                  produce and deliver an order of RAINBOW ASIC units ordered by
                  RAINBOW within a default period of 60 days of scheduled
                  deliveries; or (iii) upon the occurrence of an event described
                  in section 12.0; and

         B.       use and include the RAINBOW ASIC designed and manufactured
                  under this AGREEMENT in any current or future RAINBOW

7.0      BUSINESS STRATEGY


<PAGE>   7
         7.01     ESTABLISHING A SECOND MANUFACTURING LOCATION
         EM MARIN may, in its sole discretion, establish a second manufacturing
         location for RAINBOW ASIC production provided that it notifies RAINBOW
         in advance. RAINBOW will not be held accountable for the costs
         associated with starting a second manufacturing location.

         EM MARIN will perform the necessary tasks to establish the
         manufacturing capability at a second location if RAINBOW exercises this
         option after delivery of one (1) million pieces of the RAINBOW ASIC and
         by payment of __________________________ ($___________) to EM MARIN.

         The RAINBOW ASIC unit price shall not increase, regardless of where the
         manufacturing takes place. Pricing shall be renegotiated if more
         favorable cost structures are available at another site.

         7.02     DISCONTINUANCE OF MANUFACTURING
         If EM MARIN decides to discontinue manufacturing the RAINBOW ASIC, EM
         MARIN must notify RAINBOW in writing at least twelve (12) months in
         advance. EM MARIN will allow RAINBOW a "last buy" purchase order to
         cover the twelve (12) month period prior to the discontinue date.
         Furthermore, EM MARIN will provide reasonable assistance to transition
         the manufacturing of the product to an alternate supplier.


8.0      DURATION AND TERMINATION


         8.01     THIS AGREEMENT SHALL COME INTO EFFECT UPON SIGNATURE BY BOTH
                  PARTIES AND SHALL REMAIN IN FORCE UNTIL THE 31ST DAY OF
                  DECEMBER 2001. IT SHALL THEREAFTER IMPLICITLY BE RENEWED FOR
                  ADDITIONAL TERMS OF ONE YEAR PROVIDED (I) NEITHER PARTY IS
                  GIVING NOTICE TO THE OTHER IN WRITING AT LEAST THREE (3)
                  MONTHS IN ADVANCE AND (II) THE AGREEMENT IS NOT TERMINATED FOR
                  REASONS SET FORTH HEREINAFTER.
         8.02     If either PARTY materially breaches this AGREEMENT, the other
                  PARTY may, upon thirty (30) days written notice of such breach
                  or default, cancel its remaining obligations under this
                  AGREEMENT. In no event shall EM MARIN be liable for delay in
                  the rendering of services under this AGREEMENT due to causes
                  beyond its reasonable control, including by way of
                  illustration, but not limited to, acts of God, acts of civil
                  or military authority, fire, or inability's due to causes
                  beyond EM MARIN's reasonable control to obtain necessary
                  labor, materials, facilities, or services. In the event of
                  such a delay, the dates of performance under this AGREEMENT
                  shall be deferred for a period equal to the time lost by
                  reason of the delay. Notwithstanding such event or delay,
                  RAINBOW may, if so desires, exercise its rights under section
                  8.01. In the event that this AGREEMENT is terminated, each
                  PARTY shall return all PROPRIETARY INFORMATION and works in
                  progress received from the other PARTY.

         8.03     TERMINATION FOR CONVENIENCE OR FOR DEFAULT
         RAINBOW shall have the right, upon giving thirty (30) days written
         notice, to terminate the DEVELOPMENT PROJECT at any time. In the event
         of such termination, RAINBOW's total liability to EM MARIN shall be
         payment for the then current accumulated charges, including charges
         that were to be amortized and were expended.

         EM MARIN shall have the right, upon giving thirty (30) days written
         notice, to terminate the Development project. If this AGREEMENT is
         terminated by EM MARIN, then EM MARIN will return to RAINBOW any and
         all development charges that have already been paid at the time of
         termination with the exception of _____________________ ($________) US
         Dollars for the work up to Specification Sign-off. In such instance,
         EM MARIN will have no further liability.

         This AGREEMENT will terminate in case of the termination of the
         DEVELOPMENT PROJECT. Section 3.0, however, will survive the termination
         of this AGREEMENT for three (3) years.

                             MANUFACTURING AGREEMENT

         THIS MANUFACTURING AGREEMENT (the "Agreement") is entered into and
effective as of the 30 day of September, 1997, by and between AlliedSignal Inc.,
a Delaware corporation, by and through its Communications Systems business unit
having a principal place of business at 1300 East Joppa Road, Baltimore,

individually referred to as a "Party" or collectively referred to as the
"Parties".

         WHEREAS, the Parties have entered into in addition to this Agreement:
(a) an Asset Purchase Agreement (the "Purchase Agreement"), dated as of
September 30, 1997, which provides for the sale by AlliedSignal to Mykotronx of
certain assets including assets used in the manufacture and sale of the

such date ("Development Agreement") to develop a later generation product for
future sales (all three Agreements hereinafter referred to collectively as the
"Collective Agreements"). Capitalized terms used but not defined herein shall
have the meanings ascribed to them in the Purchase Agreement.

         WHEREAS, the Parties have determined that it is mutually desirable for
AlliedSignal to continue to manufacture the Products for and in behalf of
Mykotronx.

         WHEREAS, the Parties wish to enter into this Manufacturing Agreement
which shall set forth the terms and conditions upon which AlliedSignal shall
continue to manufacture Products for Mykotronx.


         NOW, THEREFORE, for good and valuable consideration, the receipt and
adequacy of which is hereby acknowledged, the Parties agree as follows:

1.  TERM OF AGREEMENT; TERMINATION

         (a) This Agreement shall expire on December 31, 1999, subject to
earlier termination pursuant to the provisions of this Agreement.

         (b) Mykotronx may, at its option, terminate this Agreement prior to
December 31, 1999, by giving written notice to AlliedSignal of its desire to
terminate this Agreement. Such notice shall include the effective date of the
termination which date shall be not less than 180 days after the date of such
notice. Such notice shall be given, if at all, at any time after June 30, 1998,
but not later than June 30, 1999.

         (c) Any provisions hereof that by their nature would be expected to
survive the termination of this Agreement shall survive and not be affected by
the termination or expiration of this Agreement, including, without limitation,
Sections 13, 18, 19, 23 and 24.

2.  MANUFACTURING

         A. AlliedSignal shall manufacture and/or purchase the products for
Mykotronx listed in EXHIBIT A annexed to this Agreement and made a part hereof,
to the specifications and/or part number configurations identified opposite each
product (hereinafter referred to as the "Product " or "Products"), including the
Ancillaries used in connection with the Products set forth in EXHIBIT A.

         B. The Product is a conceptual configuration and the subject of the
Development Agreement. Upon completion of development of the Product, EXHIBIT A
hereto shall be amended to add the Product to this Agreement as a Product.

3.  LICENSE TO MANUFACTURE

         For the term of this Agreement, Mykotronx does hereby grant to
AlliedSignal a non-exclusive, royalty-free, irrevocable right and license: (i)
to use all Intellectual Property transferred to Mykotronx by AlliedSignal
pursuant to the Purchase Agreement and (ii) to make Products, or have the
Products made, including purchasing the Ancillaries used in connection with the
Products.

<PAGE>   2

4.  PROHIBITION ON THIRD PARTY SALES

         AlliedSignal agrees to manufacture the Products and/or Ancillaries used
in connection with the Products exclusively for Mykotronx and further agrees not
to sell any of the Products and/or Ancillaries used in connection with the
Products to any third party unless directed to do so in writing by Mykotronx.

5.  FORECASTS

         Commencing not later than November 1, 1997, Mykotronx shall submit in
writing to AlliedSignal a forecast of Products and Ancillaries that Mykotronx
expects will be required for sale within the next six (6) months. The forecast
shall include the total quantity and type of Products and Ancillaries,
identified by part number, and such forecast shall be revised monthly. Forecasts
are for general planning purposes only and, accordingly, Mykotronx shall not be
responsible for forecasts that later turn out to be inaccurate.

6.  PURCHASE ORDERS

         A. Notwithstanding the provisions set forth in the paragraph entitled
FORECASTS, Mykotronx shall issue purchase orders ("Purchase Orders") for all
Products ordered which shall include the unit price, quantity, cumulative price,
anticipated delivery date, place of delivery and method of transportation and
carrier. Any terms and conditions contained in a Purchase Order that are
inconsistent with the terms and conditions set forth in this Agreement shall
have no force and effect unless set forth in writing executed by both Parties.
AlliedSignal agrees to accept mandatory flowdown clauses similar to those
accepted by Mykotronx in its prime contracts and to incorporate the terms and
conditions thereof in the Purchase Orders. In addition, the Parties agree to
negotiate in good faith to incorporate termination provisions similar to those
accepted by Mykotronx in its prime contract(s) with its customers for the
Products. Other additional terms and conditions shall have no force and effect.

         B. Deliveries shall be made pursuant to reasonable manufacturing
schedules based on no less than a sixty (60) day lead time.

         C. Mykotronx agrees to place Purchase Orders for a minimum quantity of
___ Units for delivery per month and shall not exceed a maximum quantity of ___
Units for delivery per month (except as contemplated otherwise in this Section
6.C). Any requirements for a quantity of less than ___ Units (but not less than
___ Units) or more than ___ Units (but not more than ___ Units) shall be priced
as provided on Part III of Exhibit B, and the delivery schedule shall be
adjusted if impacted by an order outside the _______ minimum-maximum quantity
range. "Units" shall mean, collectively, the Product embeddable _____ COMSEC
module, the Product high speed embeddable ____ COMSEC module, the ____, and the
Product (which is the subject of the Development Agreement). If the Product has
not been endorsed by the NSA by January 1, 1999, then, commencing in January
1999, and continuing on a month-to-month basis thereafter, Mykotronx shall be
relieved of its obligation to purchase a minimum number of Units until the first
calendar month after the month in which the Product receives NSA endorsement.

         D. Payment for Products and/or Ancillaries ready for delivery shall be
made by Mykotronx on a net thirty (30) basis from receipt of the invoice from
AlliedSignal with respect to deliveries under the IDIQ and on a net forty-five
(45) basis for all other deliveries (including purchase orders for Mykotronx to
be shipped to its inventory). Invoices shall be transmitted to Mykotronx at the
time the Products are deemed "accepted" as provided in Section 12 hereof.

         E. Notwithstanding anything which may be to the contrary herein,
Mykotronx shall deliver to AlliedSignal an initial Purchase Order hereunder not
later than November 1, 1997. Such initial Purchase Order shall cover Mykotronx'
orders for Products for the period October 1, 1997, through December 31, 1997,
and for each month in such period shall include orders for at least ____ Units
in the aggregate per month. In addition the Purchase Order for the month of
October 1997 shall include orders that reflect by AlliedSignal in such month
pursuant to the next sentence of this Section 6.E. For the period from October
1, 1997 through the date Mykotronx delivers the initial Purchase Order,
AlliedSignal shall continue to manufacture and ship Products in a manner that
is, at a minimum, sufficient to satisfy existing outstanding obligations under
the Customer Contracts, and Mykotronx shall be deemed to have ordered such
Products as if it had delivered a Purchase Order therefor.

7.  PRICING

         A. Pricing for the Products and/or Ancillaries ("Transfer Price") shall
remain firm through December 31, 1999, as shown in Part I of EXHIBIT B annexed
hereto and made a part of this Agreement, except that such prices may be
adjusted to reflect an increase in the cost of material (applying burden rates
applicable thereto) in accordance with the formula set forth in Part Il of
EXHIBIT B. In addition, in the event that any raw materials or component parts
are supplied by Mykotronx, an appropriate decrease will be made in the transfer
price.

         B. The price to be paid by Mykotronx to AlliedSignal for the Presidio
module on a pass-through basis shall be fixed at $____ per unit; provided,
however, that in the event that any materials relating to the Presidio module
are supplied by Mykotronx, an appropriate decrease will be made in such $____
base transfer price net of the amount, if any, accruing to the benefit of
AlliedSignal pursuant to the next sentence of this Section 7.B. In the event the
Presidio module cost is less than or exceeds the $____ unit cost, Mykotronx and
AlliedSignal shall share any price decrease benefit and/or price increase cost
on an equal basis below and above such unit cost, but AlliedSignal's maximum
liability or benefit under this provision for Presidio cost increases above or
decreases below the $____ per unit cost shall cumulatively not exceed $______.
Upon AlliedSignal incurring $______ in costs for its share of price increases in
excess of $____ per unit, Mykotronx shall thereafter be responsible for all such
costs of the Presidio module.

         C. Upon completion of the development of the Product pursuant to the
Development Agreement, an initial Transfer Price shall be established for this
new Product which shall be determined in a manner consistent with the manner in
which the initial transfer prices hereunder were determined. In furtherance and
not in limitation of the foregoing, such price shall include AlliedSignal's
material costs plus burden (at 1997 rates) and labor costs plus burden at 1998
rates, plus 1.5% for warranty and 1% for administrative requirements, with no
other general and administrative expenses included in the Transfer Price of the
Product. After the initial Transfer Price has been determined, such initial
Transfer Price shall be added to Part I of EXHIBIT B hereto, and such price
shall remain firm through December 31, 1999, except that such price may be
adjusted to reflect an increase in the cost of material (applying burden rates
applicable thereto) in accordance with the formula set forth in Part II of
EXHIBIT B or as otherwise contemplated in Section 7.B, this Section 7.C or
Section 7.D. In addition, in the event that any raw materials or component parts
are supplied by Mykotronx, an appropriate decrease will be made in the transfer
price.

         D. Notwithstanding anything which may be to the contrary herein, the
transfer price for the Product (with respect to orders placed for delivery
within the month ___ minimum/ ___ maximum Unit range) shall not exceed $ ____
per unit (the "Cap"), provided, however , that the Cap shall be increased on a
dollar for dollar basis to the extent that the cost of the Presidio module
exceeds $____ per unit. For Product Units that are ordered for delivery outside
of the monthly ___ minimum/ ___ maximum range, AlliedSignal will offer Transfer
Prices which shall be determined in a manner consistent with the 90% learning
curve methodology used to determine the ranges outside the ___ minimum/ ___
maximum ranges set forth in Part III of Section B.

         E. Attached hereto as Exhibit C is a list of the elements included in
the build up of the Transfer Price. If any element relating to price has been
included in the build up of the Transfer Price, then, notwithstanding any
provision which may be to the contrary herein, Mykotronx shall not be charged
separately for such cost elements. If it is determined that inadvertently
Mykotronx has been charged separately for a cost that is included in the
transfer price, then AlliedSignal shall give Mykotronx a credit for the amount
of such overcharge and shall thereafter cease to bill Mykotronx separately for
such charges.

8.  CHANGES

         Any changes to the drawings, designs or specifications of the Products
required by Mykotronx shall be communicated to AlliedSignal in writing. The
delivery date and the price of the Products shall be adjusted if any such
changes agreed upon by the Parties cause a delay in delivery or increase in the
costs of manufacture of the Products. Anything to the contrary notwithstanding,
AlliedSignal shall assume the costs of all changes cumulatively on a recurring
and non-recurring basis up to $______ (net of any such costs that are included
in the Transfer Price) and Mykotronx shall thereafter be responsible for the
costs incurred by AlliedSignal in implementing changes to the Products.

otherwise change the structure of the business organization manufacturing the
Products and/or the Ancillaries, AlliedSignal without the consent of any Party
may move the factory. In such event, AlliedSignal shall notify Mykotronx one
hundred twenty (120) days in advance of such move and AlliedSignal shall be

of such delinquency giving AlliedSignal sixty (60) days from the expiration of
the Notice Period to cure the delinquency ("Cure Period"), for a total of 75
days from the date the notice is received; provided, however, that the Notice
Period and Cure Period shall not apply to delays in production or delivery that
are the result of the relocation of the manufacturing operations as contemplated
in Section 9. Delivery shall be deemed complete when the Products are delivered
to the FOB point.

         B. In the event AlliedSignal fails to cure the delinquency prior to the
expiration of the Notice Period and Cure Period, AlliedSignal shall pay to
Mykotronx as liquidated damages, a sum of one percent (1%) of the Transfer Price
of the Products and/or Ancillaries that were ordered by Mykotronx' customers and
remain unshipped for each month (beyond the seventy-five (75) day Notice and
Cure Period) that such Products so remain unshipped, not to exceed a total of 
($_______) of liquidated damages in the aggregate. Anything to the contrary
notwithstanding, no liquidated damages under this section entitled DELIVERY
DATE-LIQUIDATED DAMAGES shall be due and owing: (1) for Products that remain
unshipped as of September 30, 1998 (which are addressed in the Development
Agreement); or (2) if the delays in delivery are caused by the U.S. Government
or any of its agencies or departments (which are not attributable to the
performance or non-perfonnance by AlliedSignal) or by force majeure events.

         C. In the event AlliedSignal is obligated by the terms of this
Agreement to pay liquidated damages to Mykotronx, AlliedSignal shall pay such
sum on a net thirty (30) basis from receipt of Mykotronx' invoice for same,
provided AlliedSignal does not dispute such invoice.

unusually severe weather; (b) civil or military authority, war, hostility,
riots, government action in its contractual or sovereign capacity; (c) strikes
or other labor actions; or (d) where such delay is occasioned by other causes
beyond the control of AlliedSignal and without its fault or negligence, then the
date or dates for delivery of the equipment shall be extended for a period equal
to the time lost by reason of any such delay. Anything to the contrary
notwithstanding, AlliedSignal shall be responsible for delays caused by
subcontractors failing to make timely deliveries unless such delays are caused
by force majeure events, subject to the limitations set forth in paragraph B of
the section, entitled DELIVERY DATES-LIQUIDATED DAMAGES.

3.0      WORK SCOPE

         3.1      IBM will provide Buyer with engineering support and assistance
                  and Buyer (or Mykotronx) will provide IBM with the Buyer
                  Deliverable items and cooperate with IBM in the use of IBM
                  Deliverable Items to enable IBM to manufacture Products, in
                  accordance with the SOW. The Products are designed for
                  verification on IBM ASIC tools and to be manufactured by IBM
                  under this Agreement. The terms and conditions by which IBM
                  licenses the IBM Design Kits to Mykotronx are exclusively
                  governed by the IBM Design Kit License Agreement, which is
                  hereby incorporated by reference.

         3.2      IBM will assign field design center engineering support to
                  Mykotronx regarding the use of the ASIC Tool Kit and IBM's
                  ASIC design methodology. This support may be provided to
                  Mykotronx on-site as mutually agreed to by IBM and Buyer. The
                  support obligations of IBM shall end when IBM has provided the
                  items in Attachment B under "IBM Deliverable Items".

         3.3      In the event that multiple Products are developed under this
                  Agreement or this Agreement is amended to include other
                  Products, each such Product shall be developed under and
                  subject to a separate SOW, separate development checklist and
                  separate Product pricing.

         3.4      Buyer will not utilize Products in conjunction with any
                  medical implantation or other direct life support applications
                  where malfunction may result in injury, harm or death to
                  persons, or used in conjunction with aviation, nuclear
                  materials, or other ultra-hazardous activities (collectively,
                  "Ultra-hazardous Uses"). Buyer agrees to require the same
                  commitment from its own customers in all contracts or sale
                  documents under which the customer sells the Product or a
                  device incorporating the device.

4.0      ASIC PRODUCT DESIGN

         4.1      IBM's ASIC development checklists shall document the
                  development of each of Mykotronx Product design.

                  4.1.1    The IDR will be used to make a preliminary
                           feasibility assessment of each of Mykotronx proposed
                           Product design and to advise Mykotronx of any areas
                           where Buyer's design(s) do not conform to IBM design
                           requirements.

                  4.1.2    The RTL shall include, expressly or by specific
                           incorporation, the design specifications for each
                           Product required by Mykotronx to successfully place,
                           route, time and conform to LSSD and provide static
                           timing analysis. The RTL shall also document the fact
                           that such information is available to Mykotronx and
                           has been communicated to Mykotronx before each
                           Product netlist is released to layout. Mykotronx'
                           signature on the RTL shall record Mykotronx'
                           acknowledgment of satisfactory completion of all work
                           on such Product through such Milestone.

                  4.1.3    Mykotronx' signature on the RTM shall record
                           Mykotronx' acknowledgment of (i) satisfactory
                           completion of all work on such Product through the
                           RTM Milestone and (ii) the specifications to which
                           IBM's warranty obligations, set forth in Section
                           14.0, apply. To the extent that specifications and
                           test parameters contained in the RTM vary those set
                           forth in the RTL, the specifications contained in the
                           RTM shall govern.

                  4.1.4    Mykotronx' signature on the RTL and RTM checklists
                           shall not be unreasonably withheld.

         4.2      All Milestone and Prototype delivery schedules are estimates
                  only.

         4.3      Any data relating to a Product design that Mykotronx is to
                  furnish to IBM must be compatible with IBM tools, with which
                  IBM will verify all design and engineering work for
                  conformance to IBM's technology ground rules.

         4.4      Buyer may request changes to any Product design during the
                  course of the SOW by submitting a written request to IBM. Upon
                  receipt by IBM of any such request, IBM shall promptly inform
                  Buyer of the effect of the requested change on the SOW
                  including estimated completion of the design work to
                  incorporate any requested changes and applicable price
                  increase(s), if any. IBM may, however, continue work without
                  regard to the requested change until both parties have agreed
                  in writing to adjustment in price and estimated completion
                  date terms, unless Buyer specifically notifies IBM in writing
                  to halt work.

         4.5      Buyer may, for the applicable unit price specified in Section
                  4.0 of Attachment C, order Prototypes in addition to the
                  quantity included in the NRE Charges at any time before five
                  (5) working days prior to RTM signoff. Subject to the RTM
                  signoff and adequate yield from the initial wafer lot, IBM
                  shall use reasonable efforts to deliver such additional
                  Prototypes within two (2) weeks of the estimated delivery date
                  for Prototypes.

         4.6      Subject to the terms and conditions of this Agreement, both
                  parties will exercise reasonable diligence in performing the
                  design activities set forth in the SOW for each Product.

         4.7      IBM agrees to provide Products to Mykotronx as requested by
                  Mykotronx and accepted by IBM subject to the provisions of
                  Section 5.0 and Section 6.0.

         4.8      All computer data provided to IBM by Mykotronx will be free
                  from any virus, worm or other routines that would permit
                  unauthorized access or otherwise harm software, hardware or
                  data.

5.0      PRODUCT DEMAND FORECASTS

         5.1      The first Product demand forecast agreed to by Buyer and IBM
                  is set forth in Attachment C. The forecast covers twelve (12)
                  months broken out by Product and month. During the term of
                  this Agreement, Buyer will provide IBM with updated Product
                  demand forecasts on a quarterly basis covering a rolling
                  twelve (12) month period (not to extend beyond the Contract
                  Period), which will be reviewed for approval by IBM within ten
                  (10) days of receipt by IBM. Updated forecasts shall be in
                  substantially the same format as the first forecast in
                  Attachment C. Forecasts shall be provided to IBM's Customer
                  Account Representative as identified above. Forecasts shall
                  constitute good faith estimates of Buyer's anticipated
                  requirements for Products for the periods indicated based on
                  current market conditions, and IBM's acceptance shall
                  constitute IBM's good faith intention to quote and supply such
                  requirements if requested and ordered by Buyer in accordance
                  with this Section 5.0. Notwithstanding the foregoing, Product
                  demand forecasts accepted by IBM shall not contractually
                  obligate IBM to supply, nor contractually obligate Buyer to
                  purchase, the quantities of units of Product set forth in such
                  forecasts.

         5.2      Buyer may request Products that exceed Product demand
                  forecasts previously accepted by IBM. Such requests are
                  subject to rejection by IBM for any reason, including, without
                  limitation, resource availability.

6.0      PURCHASE ORDERS

         6.1      Buyer shall order NRE Services by issuing written purchase
                  orders. Purchase orders for NRE Services will be deemed
                  accepted by IBM unless rejected in writing by IBM, specifying
                  the reasons for rejection, within fourteen (14) calendar days
                  after IBM's receipt of such purchase order.

         6.2      Buyer shall order Products by issuing written purchase orders.
                  Purchase orders for Products must be received by IBM in
                  advance, with at least the Purchase Order Lead Time specified
                  in Attachment C, to allow IBM to meet Buyer's requested
                  Shipment Date.

                  6.2.1    Requested Shipment Dates will be deemed accepted
                           (subject to the Purchase Order Lead Time) by IBM if
                           the purchase order requesting such Shipment Date is
                           accepted by IBM. If so accepted, a requested Shipment
                           Date shall constitute a Scheduled Shipment Date.
                           Buyer agrees to accept delivery of Products up to
                           thirty (30) days in advance of the Scheduled Shipment
                           Date.

                  6.2.2    Subject to IBM's written acceptance, Buyer may from
                           time to time request an improved Scheduled Shipment
                           Date. IBM will accept requests for improved Scheduled
                           Shipment Dates to the extent that request results in
                           no additional expense to IBM. If such a request will
                           result in additional expense to IBM, then IBM will
                           quote the added charges to Buyer. IBM shall not act
                           on the request without the express written
                           authorization of Buyer. Upon shipment of Product on
                           or before the agreed to date such charges shall
                           become due and payable in accordance with the payment
                           provisions of Section 9.0 of this Agreement.

         6.3      Purchase orders for Products will be deemed accepted by IBM
                  unless rejected in writing by IBM, specifying the reasons for
                  rejection, within fourteen (14) calendar days after IBM's
                  receipt of such purchase order. Purchase orders for Products
                  may be rejected by IBM if such purchase order requests a
                  quantity of Products that (i) exceeds the most recent Product
                  demand forecast accepted by IBM or (ii) a Shipment Date IBM
                  deems unacceptable, or (iii) does not comply with the terms
                  and conditions of this Agreement, or if Buyer is in breach of
                  this Agreement.

         6.4      Purchase orders issued to IBM shall include the following:

                  6.4.1    NRE Services and/or Product(s) being ordered;

                  6.4.2    quantity of units of Product requested (in increments
                           of the minimum ship pack quantity set forth in
                           Attachment C ("SPQ") only);

                  6.4.3    NRE Charges and/or unit price per Attachment C;

                  6.4.4    billing address;

                  6.4.5    shipping instructions, including carrier, destination
                           address and requested shipment dates;

                  6.4.6    reference to this Agreement and Agreement Number.

         6.5      This Agreement shall take precedence over and govern in case
                  of any additional, different or conflicting terms and
                  conditions in any purchase order(s) or any other form of
                  either party. Purchase orders and other forms of either party
                  may not vary the terms of this Agreement. Additional,
                  different or conflicting terms and conditions on a purchase
                  order or other form shall be of no effect. 

         6.6      Notwithstanding any other provision of this Agreement, in the
                  event that IBM's ability to supply the Product is constrained
                  (except as caused by Buyer) for reasons which include, but are
                  not limited to, component availability, and the Scheduled
                  Shipment Date cannot be met, IBM will reduce the quantities of
                  Products to be supplied to Buyer in proportion to the
                  reduction in quantities of products of the same technology or
                  utilizing the same manufacturing process to be supplied to
                  satisfy others. In the event of such constraint, IBM will
                  provide Buyer written notice of the constraint and the
                  quantity of Products to be supplied by the Scheduled Shipment
                  Date. Such notice shall include estimated date for delivery of
                  the balance of the order. Within ten (10) business days after
                  the date of the notice, Buyer shall have the right to notify
                  IBM, in writing, that it is canceling the balance of the order
                  which IBM will not ship by the Scheduled Shipment Date, except
                  that Buyer shall remain responsible for compensating IBM at a
                  rate to be agreed upon, for any work in process on that
                  portion of the order. Such cancellation or receipt of such
                  allocated supply and later delivery of all undelivered ordered
                  quantities after the constraint ends shall constitute Buyer's
                  exclusive remedy in the event of such supply constraint.

7.0      PRICING
                  
         7.1      Buyer shall pay IBM the NRE Charge applicable to such Product
                  as set forth in Attachment C, as well as other sums for
                  special services as are separately listed or referenced in
                  Attachment C.

         7.2      The unit price for each unit of Product ordered shall be
                  calculated at the time the applicable purchase order is
                  accepted using the Product's Price Quantity Matrix set forth
                  in Attachment C. The quantity used as an input into such Price
                  Quantity Matrix shall be the cumulative quantity of units of
                  Product as set forth on the purchase orders accepted by IBM in
                  the year of purchase, including the units of Product requested
                  in the purchase order that is the subject of such price
                  calculation. If Buyer fails to purchase _________ units of
                  Product in the first year of production, then Buyer agrees to
                  pay IBM the total amount it would have paid had it purchased
                  the units, pursuant to Attachment C, within thirty (30)
                  days after receipt of an invoice from IBM.

         7.3      Price is based on the description of the Product, as set forth
                  in Attachment A. IBM reserves the right to re-quote Product
                  prices if changes in the Product design require a different
                  chip size, package option, manufacturing technology or other
                  similar change from the Product description set forth in
                  Attachment A, but in no event shall IBM required to charge
                  Buyer a price below IBM's full cost for the Product. Prices
                  may not be increased due to fluctuations in yield or rejection
                  rates or as a result of IBM changing the location of
                  manufacture.

8.0      TITLE AND SHIPMENT

         8.1      Title and risk of loss for a Product pass to Buyer when IBM
                  delivers the Product to the carrier.

         8.2      Products shall be shipped from the manufacturing location FOB
                  for domestic U.S. destinations and ExWorks (as defined in the
                  1990 INCO Terms) for international shipments. Products shall
                  be shipped in increments of the minimum SPQ.

         8.3      In no event shall IBM be deemed to assume any liability in
                  connection with any shipment, nor shall the carrier be
                  construed as an agent of IBM.

9.0      INVOICING, PAYMENT TERMS, TAXES

         9.1      NRE Charges shall accrue and be invoiced on the schedule set
                  forth in Section 2.0 of Attachment C. IBM shall invoice Buyer
                  for all units of Product upon shipment. All payments under
                  this Agreement shall be due within thirty (30) days of the
                  date of invoice. If Buyer's account becomes in arrears or if
                  Buyer exceeds its credit limit with IBM, in addition to any
                  other right under this Agreement, IBM reserves the right to
                  cease development work or stop shipment to Buyer or ship to
                  Buyer on a cash-in-advance basis until Buyer's account is
                  again current.

         9.2      IBM reserves a purchase money security interest in Products
                  purchased under this Agreement in the amount of the price and
                  in Buyer's proceeds from the same, including, without
                  limitation, accounts receivable. Purchase money security
                  interests will be satisfied by payment in full. Buyer agrees
                  to execute UCC-1 financing statements or other appropriate
                  documents to be filed in order to perfect IBM's security
                  interest.

         9.3      Buyer is responsible for all taxes related to Products except
                  for taxes based on IBM's net income.

         9.4      Buyer shall provide IBM with a copy of a valid reseller's
                  exemption certificate for Products purchased for resale for
                  each applicable 


                                       7
<PAGE>   8

                  taxing jurisdiction. Based on such certificate, and where the
                  law permits, IBM will treat Buyer as exempt from applicable
                  state and local sales tax for Products purchased hereunder.
                  Buyer shall notify IBM promptly in writing of any modification
                  or revocation of its exempt status. Buyer shall reimburse IBM
                  for any and all assessments resulting from a refusal by a
                  taxing jurisdiction to recognize any Buyer reseller's
                  exemption certificate, or from Buyer's failure to have a valid
                  reseller's exemption certificate. If Buyer purchases Product
                  under this Agreement for internal use, Buyer agrees to notify
                  IBM and pay applicable sales tax.

10.0     INTEREST ON OVERDUE PAYMENTS Buyer will be liable for interest on any
         overdue payment under this Agreement commencing on the date such
         payment becomes due at an annual rate equal eighteen percent (18%) per
         year.

11.1     CANCELLATION CHARGES, RESCHEDULING AND ORDER CHANGE PROVISIONS

         11.1     Buyer may cancel a purchase order or any portion thereof upon
                  written notice to IBM. If Buyer cancels a purchase order for
                  NRE Services or Prototypes, or if Buyer unreasonably withholds
                  its signature from the RTL or RTM, IBM will cease further work
                  in connection with the Product and invoice Buyer for the total
                  of all unpaid NRE Charges applicable to the next Payment
                  Milestone (Section 2.0 of Attachment C), an NRE cancellation
                  charge pursuant to Section 3.0 of Attachment C and the
                  applicable unit price for any canceled Prototype devices that
                  were ordered pursuant to Section 4.5 of this Agreement. For
                  purchase orders for units of Product, a cancellation charge as
                  specified in Section 9.0 of Attachment C will immediately
                  become due for each cancelled unit.

         11.2     For a purchase order for production units which is more than
                  thirty (30) days, but less than the Purchase Order Lead Time,
                  from its Scheduled Shipment Date, Buyer may request in writing
                  a one-time deferral of the Scheduled Shipment Date for not
                  more than ninety (90) days, with no cancellation charge
                  imposed. However, if this purchase order is subsequently
                  deferred or canceled, then the cancellation charge specified
                  in Section 9.0 of Attachment C will be due.

         11.3     Cancellation charges shall not apply to those orders canceled
                  by Buyer pursuant to paragraph 6.6 above.

12.0     ENGINEERING CHANGES

         12.1     IBM may implement Engineering Changes required to satisfy
                  governmental standards, protect Product, system or data
                  integrity, or for environmental, health or safety reasons
                  ("Mandatory Engineering Changes").

         12.2     For all previously shipped Product not incorporating Mandatory
                  Engineering Changes, IBM may provide replacement Products
                  (including parts, materials and documentation) at the expense
                  of the party at fault. Buyer must use reasonable efforts to
                  install Mandatory Engineering Changes on all Buyer installed
                  Products and Products in its inventory. If IBM requests the
                  return of Products displaced by installation of replacement
                  Products, Buyer will promptly return any displaced Products to
                  IBM after installation of such replacement Products, at IBM's
                  expense.


                                       8
<PAGE>   9

         12.3     In addition to Mandatory Engineering Changes, IBM may
                  implement Engineering Changes that result in cost reductions
                  to the Product ("Elective Engineering Changes") with prior
                  approval from Buyer. Such approval shall not be unreasonably
                  withheld. IBM shall give Buyer prompt notice of Elective
                  Engineering Changes.

         12.4     IBM may make available other Engineering Changes ("Optional
                  Engineering Changes"). The cost of any Optional Engineering
                  Changes that Buyer desires to implement will be borne by Buyer
                  and will be determined through a request for quote process.


13.0     TERMINATION OF AGREEMENT

         13.1     If either party is in material default of a provision of this
                  Agreement and such default is not corrected within thirty (30)
                  days of receipt of written notice, this Agreement may be
                  terminated by the party not in default.

                  13.1.1   If Buyer terminates due to IBM default, all
                           previously accepted purchase orders shall be
                           automatically canceled without charge to Buyer,
                           except for any specific purchase order(s) that the
                           parties mutually agree not to cancel.

                  13.1.2   If IBM terminates due to Buyer default, at IBM's
                           discretion, all previously accepted purchase orders
                           shall be automatically canceled and adjustment
                           charges and cancellation charges will apply in
                           addition to any other amounts then due.

         13.2     Notwithstanding the provisions of Section 13.1, either party
                  shall have the right to terminate this Agreement immediately
                  if:

                  13.2.1   The other party files a petition in bankruptcy,
                           undergoes a reorganization pursuant to a petition in
                           bankruptcy, is adjudicated a bankrupt, becomes
                           insolvent, becomes dissolved or liquidated, files a
                           petition for dissolution or liquidation, makes an
                           assignment for benefit of creditors, or has a
                           receiver appointed for its business; or

                  13.2.2   The other party is subject to property attachment or
                           court injunction or court order which has a
                           substantial negative effect on its ability to fulfill
                           its obligations under this Agreement.

         13.3     IBM may terminate this Agreement, or its obligations with
                  respect to specifically affected Products, immediately if:

                  13.3.1   Buyer unreasonably withholds its consent for IBM to
                           make Elective Engineering Changes under Section 12.0;
                           or

                  13.3.2   IBM receives a claim or charge, or IBM otherwise has
                           a reasonable basis to believe any time during the
                           term of this Agreement, that any of the Buyer
                           Deliverable Items infringe third party intellectual
                           property rights.

         13.4     In the event this Agreement is terminated pursuant to Section
                  13.1.2, 13.2 or 13.3, all amounts due and payable to the
                  non-terminating party as of the date of such termination shall
                  become immediately due and payable.


                                       9
<PAGE>   10

         13.5     Either party may terminate this Agreement without cause upon
                  one (1) year's prior written notice to the other. If Buyer is
                  the terminating party, all previously accepted purchase orders
                  will be filled, but IBM shall not be obligated to accept
                  further purchase orders after receiving notice. If IBM is the
                  terminating party, IBM will continue to accept new purchase
                  orders pursuant to Section 6.0 during the notice period.

         13.6     All Products shipped against accepted purchase orders will be
                  subject to the terms and conditions of this Agreement
                  notwithstanding any termination or expiration of the term of
                  this Agreement. All amounts due for Prototypes or Product
                  delivered or NRE Services performed under this Agreement prior
                  to termination or expiration shall be paid in accordance with
                  the terms and conditions of this Agreement, notwithstanding
                  any such termination or expiration of this Agreement.

14.0     WARRANTIES

         14.1     IBM warrants that each unit of Product after delivery will be
                  free from defects in material and workmanship and will conform
                  to the Product Specifications as set forth in the RTM for the
                  applicable period set forth in Attachment C. Delivery to Buyer
                  of each unit of Product is deemed to occur five (5) days after
                  shipment from IBM. Buyer acknowledges that the functionality
                  of Products is contingent upon Buyer's designs and, therefore,
                  the warranty of this Section 14.1 does not apply to the
                  functionality of Products fabricated hereunder. This warranty
                  does not include repair of damage resulting from failure to
                  provide a suitable installation environment, or any use for
                  other than the intended purpose, accident, disaster, neglect,
                  misuse, transportation, alterations, or non-IBM repairs or
                  activities.

         14.2     Any unit of Product that fails to conform to the warranty of
                  Section 14.1, while under warranty, may be returned,
                  transportation prepaid by Buyer, to the location IBM
                  designates for repair, replacement or credit, at IBM's
                  discretion. IBM will repair or replace such units or provide a
                  credit to Buyer for the purchase price paid for such units by
                  Buyer. IBM will ship replacement units back to Buyer,
                  transportation prepaid by IBM, and such units of Product will
                  be considered newly delivered for warranty purposes.

         14.3     Should any unit of Product returned to IBM hereunder be found
                  by IBM to be free from defects or non-conformities, IBM will
                  return such unit of Product to Buyer transportation prepaid by
                  IBM. Payment for such unit of Product will be due and payable
                  by Buyer upon receipt of the invoice.

         14.4     Prototypes provided by IBM under this Agreement are provided
                  on an "AS IS" basis, without warranty of any kind.

         14.5     No course of dealing, course of performance, usage of trade,
                  or Product or Prototype description shall be deemed to
                  establish a warranty, express or implied.

         14.6     THE FOREGOING WARRANTIES MADE BY IBM ARE EXCLUSIVE AND IN LIEU
                  OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED INCLUDING, WITHOUT

                  FITNESS FOR A PARTICULAR PURPOSE, AND ANY IMPLIED WARRANTIES
                  OF NON-INFRINGEMENT.

15.0     CONFIDENTIAL INFORMATION - The existence and contents of this Agreement
         are confidential to the parties and neither party shall disclose the
         same without the prior written permission of the other party. If a
         party wishes to exchange other confidential information, the exchange
         will be made under the terms of the separate agreement for exchange of
         confidential information (Agreement Number Vl793) as executed between
         IBM and Mykotronx on May 8, 1997.

16.0     TRADEMARKS AND TRADE NAMES

         16.1     Neither this Agreement, nor the sale of Products hereunder,
                  shall be deemed to give either party any right to use the
                  other party's trademarks or any of the other party's trade
                  names without specific, prior written consent.

17.0     INTELLECTUAL PROPERTY RIGHTS

         17.1     Buyer represents, and IBM acknowledges Buyer's representation,
                  that all Buyer Deliverable Items for the Products are the
                  property of Buyer. Buyer represents and warrants it is the
                  rightful owner, or authorized licensee (with all requisite
                  rights to sublicense) of the Buyer Deliverable Items and all
                  other designs, information, and materials supplied to IBM
                  hereunder, and that no part of such materials knowingly
                  incorporate or infringe the intellectual property of any third
                  party.

         17.2     IBM or its licensors shall retain and have all intellectual
                  property rights (including, without limitation, mask work
                  rights) associated with any intellectual property furnished by
                  IBM in connection with this Agreement, including without
                  limitation, (i) all base array layers, (ii) all IBM-licensed
                  library elements (including, without limitation, any
                  megafunctions or cores), and (iii) all design methodologies
                  and tools, (iv) all IBM-furnished modifications of any of the
                  foregoing. To the extent Buyer has access to such intellectual
                  property, Buyer shall use such intellectual property solely
                  for the purpose of designing Prototypes and Products for
                  manufacture pursuant to this Agreement. Buyer hereby conveys
                  to IBM any intellectual property rights Buyer may acquire
                  therein.

         17.3     IBM shall own any masks made by IBM using logic data provided
                  by Buyer. IBM will use any tangible netlist tape(s), and
                  tangible GDS 11 tape(s) received from Buyer or generated
                  exclusively for Buyer hereunder, and any masks made from such
                  GDS 11 tape(s), only to manufacture Products for sale to
                  Buyer.

         17.4     If in the course of performance under this Agreement either
                  party discovers or invents any process, pattern, device or
                  other invention, that party shall be deemed the owner of such
                  discovery or invention. In the event any such invention is
                  jointly discovered or invented by the parties, the parties
                  shall be deemed joint owners of such discovery or invention
                  without any duty of accounting.

         17.5     The parties understand and agree that no license or other
                  right is granted herein to either party, directly or by
                  implication, estoppel 


                                       11
<PAGE>   12

                  or otherwise, with respect to any know-how, inventions,
                  patents, trade secrets, copyrights, mask works or other
                  intellectual property rights, except as may be required by IBM
                  to manufacture the Product(s). No additional license or other
                  right, express or implied, shall arise from the consummation
                  of this Agreement, or from any acts, statements or dealings
                  leading to such consummation.

18.0     INTELLECTUAL PROPERTY INDEMNIFICATION

         18.1     IBM shall indemnify Buyer from and against any damages finally
                  settled or awarded by a court of competent jurisdiction
                  resulting from any direct infringement of any patents or
                  copyrights of a third party in any country in which IBM sells
                  similar products that expose IBM to similar liabilities as the
                  Product, arising as a result of any of IBM's manufacturing
                  process, equipment or testing, that is not specifically
                  required by Buyer's designs, specifications or instructions.
                  IBM shall defend at its own expense, including attorney's
                  fees, any suit brought against Buyer alleging such
                  infringement. In the event that Buyer becomes enjoined from
                  using Product in its inventory due to such infringement, IBM
                  at its option and expense, will secure for Buyer the right to
                  continue to use and market the Product or modify or replace
                  the Product with a non-infringing product. If IBM determines
                  that neither of the foregoing alternatives is reasonably
                  available, Buyer may return the Product in Buyer's inventory
                  to IBM for a credit equal to the price paid for the units of
                  Product affected. IBM shall have no obligation regarding any
                  claim based upon modification of the Product by Buyer or its
                  customers, use of the Product in other than its intended
                  operating environment or the combination, operation or use of
                  the Product with non-IBM products or equipment.

         18.2     Buyer shall indemnify IBM from and against any damages finally
                  settled or awarded by a court of competent jurisdiction
                  resulting from any direct infringement of any patents or
                  copyrights of a third party in any country where Buyer uses
                  or distributes the Product, arising as a result of IBM's
                  compliance with any of Buyer's design, specifications,
                  instructions or modifications of the Product by Buyer and
                  shall defend at its own expense, including attorney's fees,
                  any suit brought against IBM alleging any such infringement.

         18.3     The rights provided in Sections 18.1 and 18.2 are contingent
                  upon the parties seeking to enforce indemnification by giving
                  prompt written notice to the indemnifying party regarding any
                  claim, demand or action for which the indemnified party seeks
                  indemnification. The indemnified party is required to fully
                  cooperate with the indemnifying party at the indemnifying
                  party's expense and shall allow the indemnifying party to
                  control the defense or settlement of any such claim, demand or
                  action, including obtaining the written consent of the
                  indemnifying party prior to any settlement proposal or
                  settlement. IBM shall have the right to waive Buyer's
                  obligations under Section 18.2 and provide for its own
                  defense, at IBM's sole discretion and expense.

         18.4     The purchase, receipt or possession of the Product from or
                  through IBM carries no license or immunity, express or
                  implied, under any patent of IBM covering the combination of
                  the Product with other products or the use of any such
                  combination, or under any patent or

                  relating to the Product or its combinations with any other
                  products.

         18.5     Except as expressly stated in this Agreement, this Section
                  18.0 states the entire liability of the parties and their
                  exclusive remedies with respect to infringement and all other
                  warranties against infringement of any intellectual property
                  rights, statutory, express or implied are hereby disclaimed.

19.0     INDEPENDENT PARTIES - Each party hereto is an independent contractor
         and is not an agent of the other party for any purpose whatsoever.
         Neither party shall make any warranties or representations on the other
         party's behalf, nor shall it assume or create any other obligations on
         the other party's behalf. IBM and Buyer agree to indemnify from and
         against any damages finally awarded by a court of competent
         jurisdiction resulting from any violation of this Section 19.0.

20.0     LIMITATION OF REMEDIES

         20.1     IBM's entire liability and Buyer's exclusive remedy are set
                  forth in this Section:

                  20.1.1   In all situations involving non-conforming or
                           defective Products furnished under this Agreement as
                           set forth in Section 14.1, Buyer's exclusive remedy
                           is the replacement of the Products or a credit to
                           Buyer of the purchase price paid for such units by
                           Buyer, at IBM's sole discretion.

                  20.1.2   IBM's liability for actual damages for any cause
                           whatsoever (other than as set forth in Section
                           20.1.1), shall be limited to the greater of 
                           ________________ (__________) or the applicable unit
                           price for the specific units of Product that caused
                           the damages or that are the subject matter of, or are
                           directly related to, the cause of action. This
                           limitation will apply, except as otherwise stated in
                           this Section, regardless of the form of action,
                           whether in contract or in tort, including negligence.
                           This limitation will not apply to the payment of
                           costs, damages and attorney's fees referred to in
                           Section 18.0. This limitation will also not apply to
                           claims by Buyer for bodily injury or damage to real
                           property or tangible personal property caused by
                           IBM's negligence.

                  20.1.3   In no event will either party be liable to the other
                           party for any lost profits, lost savings, incidental
                           damages or other consequential damages, even if
                           advised of the possibility of such damages, except as
                           provided in Section 18.0. In addition IBM will not be
                           liable for any claim based on any third-party claim,
                           except as provided in Section 18.0. Similarly, IBM
                           will not be liable for any damages caused by
                           defective or non-conforming Products located outside
                           the fifty states of the United States, the District
                           of Columbia or Puerto Rico. In no event will IBM be
                           liable for any damages caused by Buyer's failure to
                           perform Buyer's responsibilities.

                  20.1.4   In addition, IBM shall have no liability when the
                           Products are used in conjunction with any
                           Ultra-hazardous Uses.

21.0     SUBCONTRACT AND ASSIGNMENT

         21.1     IBM has the right to subcontract its responsibilities under
                  this Agreement, provided that any subcontractor retained by
                  IBM is obligated in writing to the same obligations as set
                  forth herein with respect to IBM. In the event that IBM does
                  subcontract certain portions of its responsibilities, the term
                  "employee" as used herein shall be deemed to include such
                  subcontractor and/or its employees.

         21.2     Customer shall not assign its rights under the Agreement or
                  delegate or subcontract its duties without prior written
                  consent from IBM. IBM shall be free to assign its rights under
                  the Agreement or delegate or subcontract its duties or
                  obligations under the Agreement without Customer's consent.

         21.3     During the term of this Agreement and for one (1) year
                  thereafter, Buyer shall not solicit any IBM employee who is
                  directly engaged in performing activities under this Agreement
                  to fill out an application for employment; nor shall Buyer
                  solicit the employees of any third party engaged on behalf of
                  IBM in performing activities that are related to this
                  Agreement.

22.0     COMPETITIVE PRODUCTS AND SERVICES - Neither this Agreement nor any
         activities hereunder will impair any right of IBM or Buyer to design,
         develop, manufacture, market, service, or otherwise deal in, directly
         or indirectly, other products or services including those which are
         competitive with those offered by IBM or Buyer.

23.0     PROMOTIONAL ACTIVITY - Press releases and other like publicity,
         advertising or promotional material which mention the other party by
         name, this Agreement or any term hereof shall be agreed upon by both
         parties in writing prior to any release.

24.0     FORCE MAJEURE - Except for payments due IBM, neither party shall be in
         default or liable for any delay or failure of compliance with this
         Agreement due to an act of nature, public enemy, freight embargo, or
         other cause if such act of nature, public enemy, freight embargo, or
         other cause is beyond the control of the non-performing party. A
         non-performing party shall cure as soon as practicable.

25.0     NOTICES

         25.1     All notices shall be in writing and shall be deemed delivered
                  when sent by certified mail return receipt requested.

26.0     GENERAL PROVISIONS

         26.1     This Agreement may be executed in any number of identical
                  counterparts, each of which shall be deemed to be an original,
                  and all of which together shall be deemed to be one and the
                  same instrument when each party has signed one such
                  counterpart.

         26.2     The activities of each party and its employees, agents or
                  representatives while on the other party's premises (including
                  any design center) shall comply with the host company's
                  policies and procedures for such facilities, including
                  security procedures and visitation guidelines.

         26.3     Each party will comply with all applicable federal, state and
                  local laws, regulations and ordinances including, without
                  limitation, the regulations of the U.S. Government relating to
                  the export of commodities and technical data insofar as they
                  relate to the activities under this Agreement. Buyer agrees
                  that machines, commodities, and technical data provided under
                  this Agreement are subject to restrictions under the export
                  control laws and regulations of the United States of America,
                  including, without limitation, the U.S. Export Administration
                  Act and the U.S. Export Administration Regulations. Buyer
                  hereby gives its written assurance that neither machines,
                  commodities or technical data provided by IBM under this
                  Agreement, nor the direct product thereof, will be exported,
                  or re- exported, directly or indirectly, to prohibited
                  countries or nationals thereof without first obtaining
                  applicable government approval. Buyer agrees it is responsible
                  for obtaining required government documents and approvals
                  prior to export of any machine, commodity, or technical data.

         26.4     This Agreement shall be construed, and the legal relations
                  between the parties hereto shall be determined, in accordance
                  with the substantive laws of the State of New York, without
                  regard to the conflict of laws principles thereof. Any
                  proceedings to resolve disputes relating to this Agreement,
                  shall be commenced in the State of New York. The parties
                  hereto expressly waive any right they may have to a jury trial
                  and agree that any proceeding under this Agreement shall be
                  tried by a judge without a jury.

         26.5     If any section or subsection of this Agreement is found by
                  competent judicial authority to be invalid, illegal or
                  unenforceable in any respect, the validity, legality and
                  enforceability of any such section or subsection in every
                  other respect and the remainder of this Agreement shall
                  continue in effect so long as the redacted Agreement still
                  expresses the intent of the parties. If the intent of the
                  parties cannot be preserved, this Agreement shall be either
                  renegotiated or terminated.

         26.6     No actions, regardless of form, arising out of this Agreement,
                  may be brought by either party more than two (2) years after
                  the cause of action has arisen, or, in the case of nonpayment,
                  more than two (2) years from the date the last payment was
                  due.

         26.7     This Agreement may be modified only by a written amendment
                  signed by persons authorized to so bind Buyer and IBM. This
                  Agreement shall not be supplemented or modified by any course
                  of dealing, course of

                  performance or trade usage. The term "this Agreement" as used
                  herein includes any applicable Attachments or future written
                  amendment(s) made in accordance with this Section.

         26.8     Failure by either party to insist in any instance on strict
                  conformance by the other to any term of this Agreement or
                  failure by either party to act in the event of a breach will
                  not be construed as a consent to or waiver of any subsequent
                  breach of the same or of any other term contained in this
                  Agreement

         26.9     All obligations and duties which by their nature survive the
                  expiration or termination of this Agreement shall remain in
                  effect beyond any expiration or termination, including,
                  without limitation, Sections 8.0, 9.0, 10.0, 13.6, 14.0, 15.0,
                  16.0, 17.0, 18.0. 19.0 and 20.0.

         26.10    The headings in this Agreement are for convenience only and
                  are not intended to affect the meaning or interpretation of
                  this Agreement. 

27.0     MYKOTRONX -  Mykotronx shall be bound by those provisions of this
         Agreement relevant to its performance of its obligations. However,
         Mykotronx has no rights whatsoever under this Agreement. In no event
         and under no circumstances shall Buyer make any claim or assert any
         right against IBM in any way based upon the performance of Mykotronx
         and IBM shall be able to exercise any and all rights available to it
         under this Agreement, against Buyer, based upon failure or alleged
         failure of Mykotronx to perform its obligations hereunder, as if Buyer
         had been the party that was always responsible for those obligations.
         In the event Mykotronx makes any claim against IBM arising from or in
         any way relating to this Agreement, then IBM shall be able to rely
         fully on and assert those provisions of this Agreement that limit its
         liability (Section 20, for example) and that govern choice of law
         (Section 26.4) and statute of limitations (Section 26.6). Additionally,
         Buyer shall fully defend and indemnify IBM against such claim.

28.0     SOLE AGREEMENT - The parties acknowledge that each has read this
         Agreement and its Attachments, understands them, and agrees to be bound
         by their terms and conditions. Further, the parties agree that this
         Agreement and its Attachments and the IBM Design Kit License Agreement,
         are the complete and exclusive statement of the agreement between the
         parties, which supersedes all proposals and all prior agreements, oral
         or written, and all other communications between the parties relating
         to the subject matter hereof.
