                                    PART I

ITEM 1.  BUSINESS

Zycad Corporation-Registered Trademark- (the Company)(1) founded in 1981, 
develops, manufactures and markets a broad range of high performance tools, 
design services and electronic components that help designers speed the 
process of moving their electronic products from concept to manufacturing.   
Zycad calls this process, "Design Realization."  It encompasses performing 
the steps necessary to complete design verification and get to market in the 
quickest way possible. 

Zycad's Design Realization offerings include hardware and software simulation 
verification tools, rapid prototyping vehicles, high-density programmable 
Application-Specific Integrated Circuits (ASICs) and related desktop design 
and programming tools.  This suite of products enable electronic designers to 
quickly and accurately verify their designs prior to production and support 
initial and low volume ASIC production. Verification has the goal of 
minimizing downstream problems and risks (i.e., avoiding the expensive and 
time-consuming process of redesign should a final design not work or not meet 
the customer requirements).  This process of Design Realization via 
comprehensive and fast verification throughout the design cycle ensures a 
high quality, production-ready product that meets the customers' 
time-to-market goals.

Zycad's two-fold business emphasis is on providing both the highest 
performance verification product offerings (including both simulation and 
rapid prototyping) in the Electronic Design Automation (EDA) market, and the 
highest density programmable ASICs to the ASIC designer for both design 
verification and design realization through use as a reprogrammable 
component. All development activities are focused on optimizing their future 
development and the integration of these technologies to solve customer's 
high-end, complex verification problems, the most dramatic being that of 
"system on a chip" or "system on silicon" design verification.

Customers benefit from Zycad's capabilities by:

     -  GETTING TO MARKET FASTEST at the most optimum cost. 
     -  IMPROVING PRODUCT QUALITY through more comprehensive verification.
     -  REDUCING RISK AND MANAGING COMPLEXITY through the effective 
        application of advanced design verification tools, methodologies, 
        components and services for designs with more than 50,000 gates 
        all the way up to 16 million gates.

With Zycad's wide range of verification products, customers can quickly logic 
simulate, fault simulate, and rapidly prototype their designs. Logic 
simulation is used to verify accuracy, completeness, and quality of designs 
before building hardware.  Fault simulation is used to verify the quality and 
completeness of tests developed for the design once it is manufactured.  
Rapid prototyping is the ability to replicate the operation of a portion of a 
design by using programmable ASICs or FPGAs.  It takes a more flexible 
approach than emulation systems to replicating the behavior of a system by 
allowing other system components, like processors, memory, and software, to 
be included in the prototyping environment.

Once verification is complete, the customer can actually implement their 
design in Zycad's own programmable ASIC technology.  No other EDA vendor can 
actually produce your ASIC for immediate implementation in the end use 
product.

Zycad's corporate office, and its product divisions are located in Fremont, 
California.  Sales and support offices are located throughout the United 
States, Europe, Japan and Asia. 

- -------------
(1) As used herein, the term "Company" includes Zycad Corporation and its 
    wholly-owned subsidiaries listed in Exhibit 21.1 hereto, unless the 
    context requires otherwise.

STRATEGY

             ZYCAD'S STRATEGY IS TO SPEED TIME-TO-DESIGN REALIZATION BY 
               DELIVERING THE HIGHEST PERFORMANCE DESIGN VERIFICATION 
            CAPABILITIES, TEST TOOLS AND PROGRAMMABLE ASICS IN THE WORLD.

In the development of today's electronic systems there are three fundamental, 
overriding dynamics that drive design and design challenges in the EDA market:

  -  Time-To-Market (Time-to-Volume)
  -  Silicon Resources (The number of transistors that are available on a die)
  -  Design Efficiency (How many transistors the average engineer can design 
     per hour)

The interplay of these three factors influence the size and success or 
failure of any development project and forces design engineers to seek 
improved methods of development.  

Current tools have solved many of the problems of getting the individual 
components of the system to work right the first time, but fall short in 
solving the problem for the entire system, which for many future designs will 
all be incorporated on a single chip.    

"System on a chip" developers face the following challenges:

  -  Creation of Intellectual Property (IP)
  -  Use and design reuse of IP (real design reuse of functional blocks from 
     multiple sources)
  -  Design verification and testability 
  -  Transition from a mainly hardware centric design focus to a hardware 
     and software centric emphasis 

Zycad will continue providing solutions which address the problem of 
verification complexity driven by time-to-market pressures and the push to 
"system on a chip".  The Company will enable developers to quickly verify, 
prototype and even implement the Integrated Circuits (ICs) for their complex 
electronic systems.   As with all development strategies, the ultimate 
objective is to produce the best product, at the lowest cost, as early as 
possible.  


MARKET

System architects, system engineers, hardware and software design engineers, 
and test engineers in all electronic industries confront a similar set of 
problems in evolving new products from concept to physical reality.  The most 
challenging of these design issues revolve around:

  -  SHRINKING GEOMETRIES leading to deep sub-micron design and the associated 
     design and verification issues.
  -  Almost UNLIMITED CAPACITY in terms of the number of transistors that can 
     be put on a chip.  We are approaching the era of 100 million transistors 
     on a single die.
  -  Trend towards "SYSTEM ON A CHIP" or "SYSTEM ON SILICON" which is driving 
     the requirement for commercially available IP and the design verification 
     issues associated with IP coming from multiple sources.
  -  SHRINKING PRODUCT LIFE CYCLES to the point where many high volume, 
     consumer oriented products have life cycles that are less than one year. 
     Sub-one year product life cycles have tremendous ramifications on product 
     development and manufacturing cycles.

These design challenges continue to make the product development cycle 
difficult to predict, control and manage at a time when "time" is of the 
essence.  Being late to market, whether caused by the complexity associated 
with design verification, having to do a major or minor redesign, or coping 
with widespread field failures can be catastrophic to the product and the 
companies designing them.  All companies who develop electronic products must 
overcome these design challenges and learn to live with the fundamental 
competitive fact of life that more needs to be done in less time.


                                      2
<PAGE>

Zycad's customers include:  

  -  SEMICONDUCTOR MANUFACTURERS with architecture compatibility, fast 
     time-to-volume and high quality requirements.  
  -  TELECOMMUNICATIONS MANUFACTURERS with high volume, high quality 
     and product life cycles of one year or less.
  -  MULTIMEDIA COMPANIES that need to make real-time subjective 
     measurements of their designs in order to fine-tune their products 
     before manufacturing and releasing to highly competitive markets.
  -  COMPUTER VENDORS with rapidly shortening product life cycles, requiring 
     a predictable development process and efficient system integration. 
  -  MILITARY/AEROSPACE COMPANIES with the need to integrate increasingly 
     complex avionics in reduced budget and scheduling environments. 

PROGRAMMABLE ASIC

The characteristics of today's over $20 billion ASIC market include 
non-recurring engineering costs in the several hundred thousands of dollars 
to incorporate complex designs into ASICs, lead times of up to 16 weeks (or 
sometimes longer) from completion of design verification to receiving the 
ASIC and over 50% of design starts resulting in unit volume of less than 
1,000 units.  When product life cycles are short, waiting 16 weeks has a 
dramatic impact on time-to-market and thus profitability, and if the ASIC 
doesn't meet the component or system requirements, causes even more costly 
delays and ultimately dire profit consequences.

An alternative to this traditional ASIC approach is to use programmable 
ASICs.  When design corrections are needed, designers simply reprogram the 
part and proceed with the verification process until complete.  Then, instead 
of waiting 16 or more weeks for a traditional ASIC turnaround, the 
programmable ASIC can be incorporated in the final system and customer 
shipments could start immediately upon completion of design verification and 
system integration.  

When increasing volume justifies it, the design can then be mapped to a 
traditional ASIC for unit cost savings.  But, this can be done while the 
product is already shipping to customers,  garnering market share and 
generating revenues and profit.

With the wide acceptance of top-down design methodologies, the average size 
of ASIC designs is over 50K gates and continues to grow.  CMOS gate arrays 
and cell based ASICs are highly integrated, flexible, and well supported by 
EDA tools.  But they also have high initial costs, slow turnaround time and 
require zero design defects.  Current Field Programmable Gate Array (FPGA) 
and complex PLD products avoid these drawbacks, but do not provide the high 
gate density, the flexibility, or the support for top-down design 
methodologies needed for ASIC design.

Zycad's family of ProASIC-TM- (Programmable ASIC) products, together with its 
ASIC methodology and implementation tools, provide a desktop programming 
system that allows ASIC designers to easily work within their current design 
environment to re-use functional blocks and IP from existing ASIC designs, to 
verify the implementations of their new design, and get their product to 
market faster.

ZYCAD'S PRODUCTS

Zycad offerings help designers speed the process of moving their electronic 
products from design to manufacturing.  This process is called Design 
Realization and the emphasis is on the verification phase of moving the 
design from concept into production.  Products include LightSpeed Simulation 
Servers-Registered Trademark-, Paradigm XP-Registered Trademark-simulation 
accelerators, TDX-Registered Trademark- software fault and test tools, 
ProASIC products and  ProASIC rapid prototyping vehicles and services.

Zycad's goal is to help design engineers achieve Design Realization in the 
most efficient and effective manner possible.

The product development process encompasses a host of detailed tasks at each 
stage of development.  However, from a high level perspective an idea is 
turned into an architecture and then the detailed design and iterative 
verification takes place.   The design is then defined at the physical 
implementation level in order to prepare for manufacturing.  During this 
process, test analysis can also take place in order to grade the tests that 
will be used by manufacturing to 


                                      3
<PAGE>

verify the finished product. Prior to sending the ASICs off to be 
manufactured, it is wise to verify them along with the software and other 
system components in order to ensure system and architecture compatibility.

Zycad and its products are unique in many ways, which helps the company 
maintain a strong technical lead in the industry.  A few of the key unique 
features are listed below.

PERFORMANCE
A criteria for all development at Zycad is that the products provide at least 
an order of magnitude performance improvement over other methods available in 
the marketplace. This performance is critical to both simulation and rapid 
prototyping applications required for system verification. 

ARCHITECTURE
The Company's hardware products' advantage over software-based simulators on 
traditional workstations is achieved by Zycad's unique and proprietary 
architecture. Zycad's development emphasis is on application-specific, high 
performance simulation and rapid prototyping systems; not general purpose 
machines as workstation manufacturers are designing.  With this main focus, 
Zycad employs specialized techniques, technology and architectures that 
produce systems providing an order, to orders of magnitude greater 
performance over workstations.

DESIGN HARDWARE
Zycad is an EDA company that actually uses its own tools and methodologies to 
design its hardware. We are our own end user and, therefore, have the 
opportunity to debug our tools and services in a real world environment 
before taking them to our customers.  Specifically, Zycad  incorporates  
these features into its main product lines:

     LIGHTSPEED SIMULATION SERVER
     LightSpeed is the Company's latest logic simulation accelerator and the 
     industry leading logic simulation engine.  Performing up to 10 times 
     faster than its nearest competitor, LightSpeed is the industry's first 
     massively parallel simulation platform.  LightSpeed systems 
     transparently integrate to the industry standard Verilog and VHDL 
     language and simulation environments.  The system delivers supercomputer 
     (almost emulation-like) performance for the verification of 
     microprocessors, ASICs and system designs containing up to as much as 16 
     million gates.   Prices range from $260,000 to well over $1 million.

     PARADIGM XP SIMULATION ACCELERATOR  
     The Paradigm XP family is the world's leading line of structural 
     fault simulation accelerators and the price/performance leading 
     structural logic simulation accelerator.   Systems range in price from 
     $50,000 for an entry-level model with 256,000 gate capacity to over $1 
     million for expansion to multimillion gate capacity. The Paradigm XP 
     provides powerful features that address ASIC, integrated circuit, and 
     system logic and fault verification problems including modular 
     compilation and hardware assisted toggle test.  

     Transparent interfaces are provided to popular structural 
     simulation environments including QuickSim II-TM- (Mentor Graphics-TM-), 
     Verilog-Registered Trademark- (Cadence), VantageSpreadSheet-TM- 
     (Viewlogic-TM-), MDE-Registered Trademark-/C-MDET (LSI Logic-TM-), 
     VLSI-TM- Link (Compass), VHDL System Simulator-TM- (Synopsys-Registered 
     Trademark-), ViewSim-Registered Trademark-(Viewlogic-Registered 
     Trademark-).  This allows the Paradigm XP product line to transparently 
     integrate into these environments, making it easy for the design 
     engineer to access the XP accelerators in their design environment.

     Libraries are always a main concern with our customers.  In order 
     to ease the creation of accurate libraries for the Company's LightSpeed 
     and Paradigm XP systems, Zycad has developed automated tools that will 
     accept multiple sources for library translation.

     TDX FAULT AND TEST TOOLS
     In addition to the Company's hardware-assisted fault simulation 
     products, Zycad provides a powerful suite of software testability 
     analysis and test generation tools.  These software tools include a high 
     performance fault simulator, IDDq, automated test pattern generation  
     (ATPG), and a fault manager system.  Zycad's fault and test tools help 
     customers to significantly reduce the time required for test grading and 
     to improve the efficiency of test programs which ultimately leads to 
     higher quality products.

     RAPID PROTOTYPING SYSTEM
     The Company is currently developing a fully integrated rapid 
     prototyping vehicle based on its GateField GF200F and GF250F ProASIC 
     families combined with innovative packaging technology of a third party. 


                                      4
<PAGE>

     This will enable a component form factor size solution offering 
     400,000 gates, dedicated memory blocks, and real time system performance.

     GATEFIELD PROGRAMMABLE ASICS
     The GateField GF100K, GF200F, and GF250F families of reprogrammable 
     ASICs use a unique architecture and switch technology to provide a 
     device that is comparable to a gate array in capacity and usable 
     density, while offering all the advantages of non-volatility and field 
     re-programmability.  The revolutionary Sea-of-Tiles-Registered Trademark-
     architecture coupled with GateField's ASICmaster-TM- software, provides
     the ASIC designer with unparalleled gate capacity and automation.  These 
     high density programmable ASICs currently range from 9,000 to 150,000 
     usable gates.

     GateField ASICmaster software accepts net lists from standard mask 
     programmable ASIC tools, provided by companies such as Mentor Graphics, 
     Viewlogic, Cadence and Synopsys.  ASICmaster performs place and route of 
     the design into the selected device and provides back annotated delay 
     information for simulation.  Once the design is verified, ASICmaster 
     downloads the layout into the GateField ASICmakerhigh device programmer 
     for chip programming.  Design services are provided as needed to help the 
     customer accelerate verification, complete ASIC conversions, complete 
     prototyping systems and enhance time-to-market.

PRODUCT DEVELOPMENT

Zycad is regularly engaged in ongoing research and development to further 
enhance and improve its family of high-performance design verification and 
Programmable ASIC software and hardware products.  The Company introduced its 
latest generation simulation accelerator, LightSpeed, in June 1996 and will 
continue to add enhancements and interfaces to this product line in 1997.  
The Company will also introduce several new programmable ASIC products 
ranging in densities from 25K up to 150K, as well as rapid prototyping and 
embedded memory solutions.  In fiscal year 1996, the Company expensed 
$15,783,000 on research and development, compared to $11,263,000 in 1995 and 
$11,172,000 in 1994.

MARKETING & SALES

Zycad markets its products directly and through distributors, through a 
worldwide product and service sales organization.  The Company has direct 
sales offices in North America, Europe, Japan, Korea, and Taiwan. To 
complement its direct organization, the Company also has international 
distributors in the Far East, Israel and Europe.

The Company highlights the economic benefits that can be gained from use of 
its high performance verification products and services.  In addition, 
demonstration of the products' capacity and speed to individual potential 
customers through the use of benchmark comparisons against software 
alternatives is an important element of the selling cycle. The Company's 
applications engineers, consulting engineers, and sales force are involved in 
the sales process to provide pre-sale technical assistance, technical 
credibility, and continuity with post-sale installation and servicing. 

The Company's general policy is to sell and not to lease its products; 
however, leasing arrangements are available for customers who prefer that 
option.

The rate at which orders are received by the Company may vary from month to 
month and quarter to quarter.  In addition, customers' lead times for placing 
purchase orders have varied substantially.  For these reasons, the Company's 
backlog at any particular date may not be indicative of its actual sales for 
any succeeding period.

The Company offers a maintenance agreement to its customers under which its 
applications engineers provide diagnostic, repair or replacement and 
maintenance service.  In addition, the Company offers software support and 
updates as part of this agreement.

Zycad markets its GateField Programmable ASIC products both through its 
GateField worldwide sales organization, as well as through manufacturing 
representatives.  In addition, the manufacturer of the GateField devices, 
Rohm Co. LTD. (Rohm) located in Kyoto, Japan, also markets and sells the 
ProASIC products in Japan on a non-exclusive basis.  Rohm has a strong 
marketing and sales presence in Japan through its seven design centers and 
its direct sales 


                                      5
<PAGE>

force of 300 people.  This partnership provides Zycad the opportunity to 
quickly penetrate the Japanese market, which according to the market research 
from Dataquest, constitutes 36% of the world's gate array market.  The 
ASICmaster software and the ASICmaker hardware are sold in Japan through 
Zycad's direct sales organization.

For export sales information for the three years ended December 31, 1996, see 
Note 9 to the Company's Consolidated Financial Statements in the Company's  
Annual Report to Stockholders for the year ended December 31, 1996, which 
Note has been incorporated herein by reference in Item 8.

COMPETITION

The EDA market is a dynamic market characterized by advancing technologies in 
both hardware and software. The advancing technologies frequently result in 
new product introductions, increased product capabilities and relative 
product improvements in price/performance ratios. The Company recognizes that 
rapid technological changes could impair its competitive position.

Indirect competition for the Company's system verification products consists 
primarily of software simulators that run on general purpose workstations. 
Software simulators currently hold a large share of the logic simulation 
market.  However, the Company's strategy is to leverage this large installed 
base of software simulators by selling accelerators as a complementary high 
performance point tool into the large installed base of EDA vendors whose 
customers require increased simulation performance.  Other indirect 
competition comes from emulation solutions.  However, emulation solutions are 
competition only from the perspective of total available budget dollars for 
EDA tools.

Direct competition to LightSpeed Simulation Servers comes from one other 
company with a logic hardware-assisted simulator, IKOS Systems, Inc.  Zycad 
believes that the combined features, speed, and capacity of its current and 
future products offer competitive performance and functionality advantages 
over IKOS.

Management believes that its superior products, services, and customer 
support will enable the Company to compete effectively in the EDA market 
based on the breadth, quality, features, performance and price of its product 
offerings and the neutrality, flexibility, and technological prowess of its 
services offerings.

The Programmable ASIC market is a fast growing and dynamic market with 
several large established vendors for similar products (FPGAs/CPLDs) 
including Xilinx-TM-, Altera, Actel, Lattice and Lucent.  These companies offer 
broad product lines but have not yet been very successful in providing 
high-density FPGA solutions to ASIC designers.  Their penetration into this 
market has been limited mainly by the mismatch between the top-down design 
methodologies used by ASIC designers and the design tools required to use 
their FPGAs/CPLDs effectively.  

The revolutionary flash switch technology utilized by the ProASIC family of 
products provides a 7X size advantage over switches used by SRAM-based 
devices offered by the market leaders in higher gate count devices.  This 
switch technology is used in a Sea-of-Tiles architecture to create devices 
that have a 2X-4X density advantage over the competitive offerings.  Unlike 
competing devices, the Sea-of-Tiles architecture has been designed 
specifically to work seamlessly in the top-down design flow used by today's 
ASIC designers.  The GateField devices offer the ASIC designer not only high 
density but also allow the designer to remain within his established design 
environment.

PATENTS AND TRADEMARKS

Due to the rapid pace of technological advancement, the Company believes 
that, while the protection of proprietary information is important, it must 
continue to develop and market new products to remain competitive.  The 
Company protects its proprietary product information through issuance of 
patents, use of employee nondisclosure agreements and by limiting access to 
sensitive information.  On July 2, 1985, United States Patent No. 4,527,249 
was issued to the Company for "Concurrent Fault Simulation for Logic 
Designs", and on April 5, 1988, United States Patent No. 4,736,338 was issued 
to the Company for a "Programmable Look Up System".  These patents are 
effective for a period of 17 years from the issue date and the Company 
believes that these patents are an important factor in the protection of its 
proprietary information.  On May 17, 1989, the Company signed a Patent Cross 
License Agreement with IKOS Systems, Inc., under which both companies granted 
to each other a perpetual non-exclusive license for logic or fault simulation 
products utilizing inventions covered by its respective patents issued 
through May 1, 1994.


                                      6
<PAGE>

On October 10, 1995, United States Patent No. 5,457,653 was issued to the 
Company for a "Technique to Prevent Reprogramming a Floating Gate Transistor 
used to Directly Switch a Large Electrical Signal".  In addition, on February 
14, 1996, United States Patent No. 8,508,914 was issued to the Company for a 
"Nonvolatile Reprogrammable Interconnect Cell with FN Tunneling and 
Reprogramming Method Thereof"; on January 14, 1997, United States Patent No. 
5,594,636 was issued to the Company for a "Logic Cell and Routing 
Architecture in a Field Programmable Gate Array"; and on January 14, 1997, 
United States Patent No. 5,594,698 was issued to the Company for "Random 
Access Memory (RAM) Based Configurable Arrays".  These are the first patents 
issued for the GateField ProASIC technology and seven more patent 
applications  are pending at this time.

The Company has obtained federal trademark registration for its trademark 
"Zycad Corporation" from the United States Patent and Trademark Office.

EMPLOYEES

At December 31, 1996, the Company had 182 employees.  The employees are not 
represented by a labor organization and the Company considers its relations 
with its employees to be good.

MANUFACTURING

The Company's accelerator products utilize a technology which has significant 
impact upon its manufacturing activities.  The efficient use of full custom 
ICs dramatically reduces both assembly and test time.  In addition, custom 
ICs tend to operate more reliably than a functionally equivalent printed 
circuit board due to a number of factors including the reduction of solder 
points and external contacts.

Product configurations include standard computer components such as a 
controller, central processing unit (CPU) and main memory which are selected 
from various independent suppliers on the basis of cost, reliability and 
performance properties.  These standard components are connected utilizing 
proprietary bus structures and controlled using operating systems with 
proprietary extensions as they interact with the Company's custom IC-based, 
application-specific subsystems.

The Company contracts out certain manufacturing steps, including printed 
circuit fabrication and assembly, circuit board wiring, cabinet fabrication 
and assembly, sheet metal fabrication and painting, and performs final 
assembly, configuration, testing and quality control procedures itself.  
Circuit boards are wired by automated equipment on computerized instructions 
generated on the Company's own Computer Aided Engineering (CAE) system, which 
is used extensively in order, design and test phases. Manufacturing 
efficiency is enhanced by testing each circuit board on the Company's test 
equipment.  After final assembly and configuration, each simulation system 
undergoes additional "burn in" testing.

The Company's ProASIC products are manufactured by Rohm, located in Kyoto, 
Japan under a manufacturing and development partnership agreement.  GateField 
and Rohm have built a strong working alliance that dates back to October 
1993.  Rohm is widely recognized for its expertise in Large Scale Integration 
(LSI) manufacturing and as one of the pioneers in flash technology.  As part 
of the agreement, the company has secured guaranteed wafer capacity 
sufficient to meet the expected product needs for the foreseeable future.  
Packaging for the GateField parts is done by well established assembly houses 
located in the Philippines and in Hong Kong.  The company performs wafer sort 
and final test at its facilities in Fremont, California, but as volume 
dictates, these activities may be moved offshore.  Currently, Zycad has 
sufficient capacity to meet its present manufacturing requirements through 
1997 and the foreseeable future.

ITEM 2.  PROPERTIES

The Company occupies approximately 61,000 square feet of office space in 
Fremont, California for its headquarters, manufacturing and engineering 
operations.  The total lease payments remaining amount to approximately $1.6 
million. The lease expires August 1999.  The Company's Service Division in 
New Jersey, occupies approximately 37,000 square feet of office space.  Total 
lease payments remaining through February 1998 amount to approximately $1.0 
million.  For additional information, see Note 6 to the Company's 
Consolidated Financial Statements in the Company's  Annual Report to 
Stockholders for the year ended December 31, 1996, which note has been

COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

Section 16(a) of the Securities Exchange Act of 1934 requires the Company's 
officers and directors, and persons who own more than ten percent of a 
registered class of the Company's equity securities, to file reports of 
ownership on Form 3 and changes in ownership on Form 4 or 5 with the SEC.  
Such officers, directors and ten-percent stockholders are also required by 
SEC rules to furnish the Company with copies of all Section 16(a) forms that 
they file.


                                      10
<PAGE>

Based solely on its review of the copies of such forms received by it, or 
representations from certain reporting persons that no Forms 5 were required 
for such persons, the Company believes that, during the last fiscal year, all 
Section 16(a) filing requirements applicable to its officers, directors, and 
ten-percent stockholders were complied with.

price of $3.63 per share.  Both of these warrants are exercisable for 10,000 
shares on each anniversary date.

All warrants expire eight (8) years after their respective issue dates or 90 
days after resignation from the Board of Directors, whichever occurs first.

See "Compensation Committee Interlocks and Insider Participation" for 
information regarding consulting fees paid to a director during 1996.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation Committee currently consists of outside directors James 
Fiebiger and Benjamin Huberman.  Neither of these individuals was at any time 
during the fiscal year ended December 31, 1996, or at any other time an 
officer or employee of the Company.

During fiscal year ended December 31, 1996, the Company paid Mr. Benjamin 
Huberman, a member of the Board of Directors, $80,000 in consulting fees.  
Mr. Huberman has worked closely with the Company in developing and marketing 
the Company's consulting services.  Management believes that this arrangement 
is at least as favorable as could be negotiated with outside consultants.

During fiscal year ending December 31, 1996, the Company paid Dr. James 
Fiebiger, a member of the Board of Directors, consulting fees in the amount 
of $24,875.  Dr. Fiebiger's consulting services were rendered for product 
development, strategic planning and marketing consulting services for Field 
Programmable Gate Array Products developed by the Company's GateField 
Division.  Management believes that this arrangement is at least as favorable 
as could be negotiated with outside consultants.

No executive officer of the Company serves as a member of the board of 
directors or compensation committee of any entity which has one or more 
executive officers serving as a member of the Company's Board of Directors or 
Compensation Committee.

For the purposes of complying with the amendments to the Rules 
governing Form S-8 (effective July 13, 1990) under the Securities 
and Exchange Act of 1933, the undersigned hereby undertakes as 
follows, which undertaken shall be incorporated by reference into 
the Registrant's Registration Statements on Form S-8 (File Nos. 
13244):

Insofar as indemnification for liabilities arising under the 
Securities Act of 1933 may be permitted to directors, officers and 
controlling persons of the Registrant pursuant to the foregoing 
provisions, or otherwise, the Registrant has been advised that in 
the opinion of the Securities and Exchange Commission such 
indemnification is against public policy as expressed in the 
Securities Act of 1933 and is, therefore, unenforceable.  In the 
event that a claim for indemnification against such liabilities 
(other than the payment by the Registrant of expenses incurred or 
paid by a director, officer or controlling person of the Registrant 
in the successful defense of any action, suit or proceeding) is 
asserted by such director, officer or controlling person in 
connection with the securities being registered, the Registrant 
will unless in the opinion of its counsel the matter has been 
settled by controlling precedent, submit to a court of appropriate 
jurisdiction the question whether such indemnification by it is against 
public policy as expressed in the Act and will be governed by the final 
adjudication af such issue.

                                   RECITALS


WHEREAS, Shareholders are the owners and holders of all of the issued 
and outstanding shares of the capital stock of Attest and all of the 
options therefor; and

WHEREAS, Attest is a corporation duly organized and existing under the 
laws of California with authorized capital stock consisting of

                           MERGER AND REORGANIZATION
                                       
1.1  On the Closing Date, as defined in this Agreement, a merger shall 
     take place ("the Merger") whereby Subsidiary shall be merged with 
     and into Attest, and Attest shall be the Surviving Corporation.  
     (The term "Surviving Corporation" appearing in this Agreement 
     denotes Attest after consummation of the Merger.)  Attest's 
     corporate name, existence, and all its purposes, powers, and 
     objectives shall continue unaffected and unimpaired by the Merger, 
     and as the Surviving Corporation it shall be governed by the laws 
     of the State of California and succeed to all of Subsidiary's 
     rights, assets, liabilities, and obligations in accordance with the 
     California General Corporation Law.

1.2  For Federal income tax purposes, the Merger shall constitute a tax 
     free reorganization within the meaning of Section 368(a) of the 
     Internal Revenue Code of 1986, as amended.

                                  ARTICLE TWO
                                       
                             CONVERSION OF SHARES

2.1  On the Closing Date:

     (a) Each share of Subsidiary's common stock issued and outstanding 
     immediately before the Closing Date shall be converted into one 
     share of common stock of the Surviving Corporation; and

     (b) All of the shares of Attest's common stock issued and 
     outstanding on the Closing Date consisting of 2,679,106 shares (the 
     "Attest Common Stock"), shall by virtue of the Merger and without 
     action on the part of the Shareholder be converted into an 
     aggregate of 387,098 shares of Zycad Common Stock ("Zycad Stock") 
     at an exchange ratio of .1444877 share of Zycad Stock for each 
     share of Attest Common Stock.  Any fraction of a share of Zycad 
     Stock shall be eliminated by rounding down to the nearest full 
     share.

2.2  The number of shares of Zycad Stock to be exchanged for the Attest 
     Common Stock as specified in Section 2.1(b) is based on a Closing 
     Price of Zycad Common Stock of $6.20  per share (Closing Price is 
     defined as the average daily closing price [last trade] of Zycad 
     Common Stock as reported on NASDAQ for the 15 days preceding the 
     date hereof. Adjustments to the number of shares of Zycad Stock 
     shall be made, subject to the limitations of Section 12.4, if the 
     following formula results in a sum that is less than $130,000:

     (Cash as of the hereof date + proceeds from the exercise of stock 
     options + prepaid expenses + accounts receivable as of the hereof 
     date + sales made by Attest but not invoiced prior to the Closing 
     Date) less (total liabilities including all accruals for expenses 
     related to Attest's business through the hereof date).  Amounts 
     representing accounts receivable and sales made but not invoiced 
     shall be limited to those are, to Attest's knowledge, collectible.  
     All liabilities that should be accrued as of the hereof date under 
     generally accepted accounting principles shall be included in the 
     foregoing formula, whether or not they were accrued as liabilities 
     on the May 31, 1996 Balance Sheet.

     No adjustment in the number of shares shall be made if the above 
     computation results in an amount greater than $130,000.

2.3  One-half of the Zycad Stock  shall be delivered to the Shareholders 
     on the Closing Date on a prorata basis based on their respective

     respective ownership interest and shall be released on the same 
     prorata basis in accordance with the following schedule:

     a.  One half of the Escrowed Stock shall be released upon the public 
         announcement of Zycad's fiscal First Quarter 1997 financial results, 
         provided there is a minimum of $1,200,000 in revenue generated from 
         the sale and support of Attest Software Products during the period 
         April 1, 1996 through March 31, 1997, (including revenue from sales 
         made by Attest but not invoiced prior to Closing) which includes 
         current Attest Products, as well as new versions or updates created 
         by Zycad from the Attest Software source code ("Attest Software 
         Revenue").

         In the event that there is less than $1,200,000 in Attest Software 
         Revenue as stated above, but at least $800,000 in such revenue, the 
         one half of the Escrowed Stock shall be released on a prorata basis,

         one half of the Escrow Stock shall be released.

     b.  A total of one-eighth of the Escrowed Stock shall be released upon 
         the public announcement of Zycad's Second Quarter 1997 financial 
         results provided there is a minimum of $300,000 in Attest Software 
         revenue in Second Quarter 1997.

         A total of one-eighth of the Escrowed Stock shall be released upon 
         the public announcement of Zycad's Third Quarter 1997 financial 
         results provided there is a minimum of $300,000 in Attest Software 
         revenue in  Third Quarter 1997.

         A total of one-eighth of the Escrowed Stock shall be released upon

         results provided there is a minimum of $300,000 in Attest Software

         results provided there is a minimum of $400,000 in Attest Software 
         revenue in  First Quarter 1998.

         In the event there is less than $1,300,000 in Attest Software 
         Revenue for the period April 1, 1997 through March 31, 1998, but at 
         least $900,000 in such Revenue, the balance of the one half of the 
         Escrowed Stock scheduled to be released  during this period which 
         remain unreleased and held in escrow shall be released on a prorata 
         basis, e.g., if the Attest Software Revenue equals $900,000, 69.23% 
         of such unreleased shares of the one half of the Escrow Stock 
         scheduled to be released shall be released.

         Shareholder is still a Zycad employee on June 30, 1998.

     f.  Notwithstanding anything to the contrary in this Section 2.4, if any 
         of the following occurs, the balance of the Escrowed Stock that is, 
         at the time such event occurs, still subject to the release 
         provisions of subsections a through e above, shall be released to

         to that Shareholder upon the later of (i) said termination of 
         employment, or (ii) one (1) year after the Closing Date, (subject, 
         however, to Article Twelve below).

     g.  Any Escrowed Stock remaining in escrow after the conditions

2.10 Claims against the Escrowed Stock shall be satisfied by 
     transferring to Zycad the number of shares determined by dividing 
     the amount of each Shareholders' share of a claim (less his pro 
     rata share of the aggregate deductible amount stated in Section 
     11.4(a)) by the greater of $6.20 or the average daily closing price 
     (last trade) of Zycad common stock as reported on NASDAQ for the 15 
     days preceding the date on which such claim is deemed to be 
     matured.  Alternatively, Shareholders may pay the amount of the 
     claim in cash within fifteen (15) days of notice to Shareholders, 
     in which case the number of shares that would otherwise be 
     transferred to Zycad shall thereafter, be subject only to the 
     restrictions of Section 2.4 above and future claims, if any, under 
     Article Twelve.

4.6  Financial Information

     Attest has delivered to Zycad copies of the following financial 
     statements (collectively the "Financial Statements"): (i) the 
     unaudited results of operations (Statement of Profit and Loss) of 
     Attest for the three-month periods ended June 30, 1995, September 
     30, 1995, December 30, 1995,  March 31, 1996, and for the one-month 
     period ended April 30, 1996 and (ii) the unaudited balance sheet of 
     Attest as of June 30, 1995, September 30, 1995,  December 30, 1995, 
     March 31, 1996,  April 30, 1996, and May 31, 1996 (the "Balance 
     Sheet").  Attest shall deliver to Zycad as soon as practicable 
     prior to the Closing Date Proforma financial statements as of the 
     Closing Date.

     The Financial Statements, (including the notes thereto, if any) 
     were prepared by Attest management in accordance with the books and 
     records of Attest.  Except as described on Schedule 4.6 
     Shareholders believe and represent that the Financial Statements 
     fairly and accurately present the business operations for the 
     periods covered by said statements in all material respects.  None 
     of Attest's books and records, has been compiled or audited by a 
     Certified Public Accountant; and there can be no assurance that any 
     of the foregoing is in conformity with generally accepted 
     accounting principles.

     The tangible assets reflected in the Balance Sheet are shown 
     thereon at actual cost, less depreciation and amortization, and in 
     the case of plant and equipment are, to the best of Attest's 
     knowledge, in good operating condition and state of repair.  A true 
     and complete list of all tangible assets of Attest as of May 31, 
     1996 is attached hereto as Schedule 4.6(a).

     Except as set forth in Schedule 4.6(b) attached hereto, all 
     accounts receivable reflected in the Balance Sheet at the date 
     thereof were bona fide accounts receivable resulting from the sale 
     of goods and services in the ordinary course of business, and, 
     shareholders have no reason to believe, such accounts receivable 
     are not collectible in full in the ordinary course of business or 
     are subject to conditions to payment, offsets, counterclaims, 
     defenses of any kind, returns, allowances or credits.  There is no 
     allowance for warranty reserve reflected in the Financial 
     Statements.  Zycad shall have the right to indemnification pursuant 
     to Section 12.1 of this Agreement for any accounts receivable 
     arising from Attest product shipment prior to Closing which is not 
     collected in full within ninety (90) days after Closing with 
     commercially reasonable collection efforts by Zycad.  The amount to 
     be indemnified shall be the unpaid balance on said 90th day.  
     Shareholders will receive credit for any monies collected by Zycad 
     within 120 days after Closing.

4.7  Absence of Undisclosed Liabilities

     Except as set forth in Schedule 4.7 attached hereto, at the date of 
     each such balance sheet Attest had no material liabilities (fixed 
     or contingent, including without limitation any tax liabilities due 
     or to become due) which were not fully disclosed, reflected or 
     provided for in each such balance sheet.  The officers of Attest 
     and the Shareholders have no knowledge of any facts which would 
     form the basis for the assertion of any material claim or liability 
     which is not disclosed, reflected or provided for in each such 
     Balance Sheet or described in Schedule 4.7 hereto.

         securities convertible into capital stock of Attest; or (iii) any

         event, riot, act of God or the public enemy or damage, destruction

         otherwise), assets, liabilities or business of Attest, or any such 
         event known to the officers of Attest or the Shareholders which 
         reasonably could be expected to materially adversely affect the 
         condition (financial or otherwise), assets, liabilities or business 
         of Attest;

     f.  any increase in compensation payable to or for the benefit of, or 
         committed to be paid to or for the benefit of, any director,

     it, including those reflected in the Financial Statements (except 
     for properties and assets sold or otherwise disposed of in the 
     ordinary course of business since that date), subject to no 
     mortgage, pledge, lien, security interest, conditional sale 
     agreement, encumbrance or charge.  Except as set forth in Schedule 
     4.10, Attest is not in default under the terms of any material 
     lease or sublease of any properties leased or subleased by it, and 
     such leases or subleases are valid and enforceable leases or 
     subleases for such properties.  Except as set forth in Schedule 
     4.10, the property shown on the Balance Sheet constitutes all of 
     the tangible personal property utilized by Attest in the conduct of 
     its business as presently conducted.

4.11 Patents, Trademarks, Etc.

     Attached hereto as Schedule 4.11 is a true and complete list and 
     summary description of all patents, patent applications, shop 
     rights, know-how, inventions (whether or not patentable), 
     trademarks and service marks and registrations thereof, trade 
     names, trade secrets, confidentiality rights and agreements, 
     copyrights, copyright registrations, proprietary ideas, licenses 
     and interests therein (individually and collectively referred to as 
     the "Intellectual Property Right(s)") presently owned or held by 
     Attest.  Where an Intellectual Property Right is held by Attest as 
     a licensee under a license or sublicense or otherwise in any form 
     or manner other than as owner of clear title, this is so designated 
     in Schedule 4.11.  Such Intellectual Property Right(s) are all such 
     rights that are required to enable Attest to conduct its business 
     as now conducted and as proposed to be conducted.  Except as set 
     forth in Schedule 4.11, the business currently and proposed to be 
     conducted by Attest does not infringe and has not infringed the 
     rights of others, including without limitation any rights under 
     patents, patent applications, shop rights, know-how, inventions, 
     trademarks, service marks, trade names, trade secrets, copyrights, 
     contracts (whether express or implied in fact or in law), 
     proprietary ideas, licenses, privacy rights or interests therein.  
     To the best knowledge of Attest and the Shareholders,  no 
     third-party is violating or has violated any of the Intellectual 
     Property Rights of Attest.  Except as set forth in Schedule 4.11, 
     Attest is the sole and absolute owner of the Intellectual Property 
     Rights and has full right and authority to utilize the Intellectual 
     Property Right(s) and other processes, systems and techniques 
     presently employed, or proposed to be employed, by it in the 
     research, design, scale-up, manufacture, and marketing of its 
     products or projected products, and all rights to such Intellectual 
     Property Right(s) and other 



                                       14
<PAGE>

     processes, systems and techniques developed by any employee of Attest 
     or developed for Attest by any consultant or third party have been duly 
     and validly assigned to Attest without any restriction or unpaid or 
     continuing royalty or other obligation. Except as set forth in 
     Schedule 4.11, no third party and no affiliate, officer, director, or 
     employee of Attest, nor any associates of any such person, owns or 
     holds, directly or indirectly, any interest in any Intellectual Property 
     Right(s) used or planned to be used by Attest.  Except as limited by 
     the Export Control Act, Attest has the unrestricted right to license, 
     sublicense, or otherwise authorize any party whatsoever, anywhere 
     in the world, to use and exercise any or all of the Intellectual 
     Property Right(s), and, except as stated in Schedule 4.11, Attest 
     has not granted any such license, sublicense, or authority.  The 
     closing and consummation of the transactions contemplated under 
     this Agreement shall create no restriction under, nor have any 
     other effect upon, Attest's right in, to, and under any of the 
     Intellectual property Right(s).  Except as expressly set forth in 
     Schedule 4.11, Attest has not agreed to indemnify any person or 
     entity for patent, service mark, trade secret, trademark, or 
     copyright infringement as to any equipment, materials, products, 
     services, or supplies which Attest produces, uses, provides, 
     license, leases, sells or distributes.  Attest has taken reasonable 
     security measures to protect the secrecy, confidentiality and value 
     of its trade secrets.

     the contracts and commitments set forth in Schedule 4.12 hereto and 
     of all other material contracts and commitments to which it is a

     party asserted that Attest is in default under any thereof nor, to 
     the knowledge of the officers of Attest and the Shareholders, does 
     any condition exist which with the passage of time or the giving of 
     notice would constitute a default under any thereof.

         or (ii) any claim against the Escrowed Stock under Article Twelve 
         disproportionate to the number of shares of Zycad Stock the 
         Shareholders received in exchange for their Attest Shares.

12.3 Notice and Opportunity to Defend

     Promptly after receipt by Zycad, on the one hand, or the Shareholders, 
     on the other hand, of notice of any action, proceeding or claim that 
     could give rise to a right of indemnification pursuant to Section 12.1 
     or 12.2 hereof, Zycad or Shareholders, as the case may be, shall give 
     the party who may become obligated to provide indemnification hereunder 
     (the "Indemnifying Party") written notice describing in reasonable 
     detail the facts and circumstances surrounding such claim within 10 days 
     of receiving such notice or otherwise becoming aware of the facts 
     constituting the claim. The Indemnifying Party shall have the right, at 
     its option, to compromise or defend, at its own expense and by its own 
     counsel, any such matter, including but not limited to an asserted 
     liability against the party seeking such indemnification, provided, 
     however, that the Indemnifying Party shall not settle a claim against 
     the Indemnified Party without the Indemnified Party's prior written 
     consent, which shall not be unreasonably withheld. If any Indemnifying 
     Party shall undertake to compromise or defend any such asserted 
     liability, it shall promptly notify the party seeking indemnification 
     (the "Indemnified Party) of its intention to do so, and the Indemnified 
     Party shall cooperate fully with the Indemnifying Party and its counsel 
     in the compromise of, or defense against, any such asserted liability. 
     In any event, the Indemnified Party shall have the right at its own 
     expense to participate in the defense of such asserted liability. Under 
     no circumstances shall the Indemnified Party compromise any such 
     asserted liability without the written consent of the Indemnifying Party 
     unless the Indemnifying Party has failed or refused to undertake the 
     defense or compromise of any such asserted liability after a reasonable 
     period of time not to exceed thirty (30) days has elapsed since the 
     Indemnifying Party received notice of a claim for indemnification 
     pursuant to this Section 12.3 hereof. The parties acknowledge that the 
     indemnification obligations set forth in this Article 12 were negotiated 
     between the parties.

12.4 Limitation

     a.  No indemnity shall be payable to Zycad with respect to any claim 
         arising under Section 12.1 hereof unless the aggregate amount of 
         Damages due from Shareholders with respect to all such claims shall 
         exceed $25,000 in the aggregate, whereupon all amounts then due from 
         Shareholders with respect to claims aggregating in excess of $25,000 
         shall be payable on demand, and all such amounts thereafter due from 
         Shareholders with respect to such claims shall be payable on demand. 
         This limitation 


                                      29

         the representations and warranties contained in Section 4.5 of this 
         Agreement.

     b.  No indemnity shall be payable to Shareholders with respect to any 
         claim arising under Section 12.2 unless the aggregate amount of 
         Damages due from Zycad with respect to such claims shall exceed 
         $25,000 in the aggregate, whereupon all amounts then due from Zycad 
         with respect to such claims aggregating in excess of $25,000 shall 
         be payable on demand, and all such amounts thereafter due from Zycad 
         with respect to such claims shall be payable on demand.

     c.  The amount of Damages for which the Indemnifying Party may be liable 
         for indemnification shall be reduced by the amount of any insurance

2.  PURCHASE AND SALE OF RECEIVABLES.

    2.1. OFFER TO SELL RECEIVABLES.  During the term hereof, and provided 
that there does not then exist any Event of Default or any event that with 
notice, lapse of time or otherwise would constitute an Event of Default, 
Seller may request that Buyer purchase receivables and Buyer may, in its sole 
discretion, elect to purchase receivables. Seller shall deliver to Buyer an 
Invoice Transmittal with respect to any receivable for which a request for 
purchase is made. An authorized representative of Seller shall sign each 
Invoice Transmittal delivered to Buyer. Buyer shall be entitled to rely on 
all the information provided by Seller to Buyer on or with the Invoice 
Transmittal and to rely on the signature on any Invoice Transmittal as an 
authorized signature of Seller.

    2.2.  ACCEPTANCE OF RECEIVABLES.  Buyer shall have no obligation to 
purchase any receivable listed on an Invoice Transmittal. Buyer may exercise 
its sole discretion in approving the credit of each Account Debtor before 
buying any receivable. Upon acceptance by Buyer of all or any of the 
receivables described on any Invoice Transmittal, Buyer shall pay to Seller 
80(%) percent of the face amount of each receivable Buyer desires to 
purchase. Such payment shall be the "Advance" with respect to such 
receivable. Buyer may, from time to time, in its sole discretion, change the 
percentage of the Advance. Upon Buyer's acceptance of the receivable and 
payment to Seller of the Advance, the receivable shall become a "Purchased 
Receivable." It shall be a condition to each Advance that (i) all of the 
representations and warranties set forth in Section 6 of this Agreement be 
true and correct on and as of the date of the related Invoice Transmittal and 
on and as of the date of such Advance as though made at and as of each such 
date, and (ii) no Event of Default or any event or condition that with 
notice, lapse of time or otherwise would constitute an Event of Default shall 
have occurred and be continuing, or would result from such Advance. 
Notwithstanding the foregoing, in no event shall the aggregate amount of all 
Purchased Receivables outstanding at any time exceed Three Million One 
Hundred Twenty Five Thousand and No/100 **** Dollars ($3,125,000.00).


                                                                 Page 1 of 6
<PAGE>

    2.3  EFFECTIVENESS OF SALE TO BUYER.  Effective upon Buyer's payment of 
an Advance, and for and in consideration therefor and in consideration of the 
covenants of this Agreement, Seller hereby absolutely sells, transfers and 
assigns to Buyer, all of Seller's right, title and interest in and to each 
Purchased Receivable and all monies due or which may become due on or with 
respect to such Purchased Receivable. Buyer shall be the absolute owner of 
each Purchased Receivable. Buyer shall have, with respect to any goods 
related to the Purchased Receivable, all the rights and remedies of an unpaid 
seller under the California Uniform Commercial Code and other applicable law, 
including the rights of replevin, claim and delivery, reclamation and 
stoppage in transit.

     2.4  ESTABLISHMENT OF A RESERVE.  Upon the purchase by Buyer of each 
Purchased Receivable, Buyer shall establish a reserve. The reserve shall be 
the amount by which the face amount of the Purchased Receivable exceeds the 
Advance on that Purchased Receivable (the "Reserve"); provided, the Reserve 
with respect to all Purchased Receivables outstanding at any one time shall 
be an amount not less than 20(%) percent of the Account Balance at that time 
and may be set at a higher percentage at Buyer's sole discretion. The reserve 
shall be a book balance maintained on the records of Buyer and shall not be a 
segregated fund.

3.   COLLECTIONS, CHARGES AND REMITTANCES.

     3.1  COLLECTIONS.  Upon receipt by Buyer of Collections, Buyer shall 
promptly credit such Collections to Seller's Account Balance on a daily 
basis; provided, that if Seller is in default under this Agreement, Buyer 
shall apply all Collections to Seller's Obligations hereunder in such order 
and manner as Buyer may determine. If an item of collection is not honored or 
Buyer does not receive good funds for any reason, the amount shall be 
included in the Account Balance as if the Collections had not been received 
and Finance Charges under Section 3.2 shall accrue thereon.

     3.2  FINANCE CHARGES.  On each Reconciliation Date Seller shall pay to 
Buyer a finance charge in an amount equal to 1.5(%) percent per month of the 
average daily Account Balance outstanding during the applicable Reconciliation 
Period (the "Finance Charges"). Buyer shall deduct the accrued Finance 
Charges from the Reserve as set forth in Section 3.5 below.

     3.3  ADMINISTRATIVE FEE.  On each Reconciliation Date Seller shall pay 
to Buyer an Administrative Fee equal to .80(%) percent of the face amount of 
each Purchased Receivable first purchased during that Reconciliation Period 
(the "Administrative Fee"). Buyer shall deduct the Administrative Fee from 
the Reserve as set forth in Section 3.5 below.

     3.4  ACCOUNTING.  Buyer shall prepare and send to Seller after the close 
of business for each Reconciliation Period, an accounting of the transactions 
for that Reconciliation Period, including the amount of all Purchased 
Receivables, all Collections, Adjustments, Finance Charges, and the 
Administrative Fee.  The accounting shall be deemed correct and conclusive 
unless Seller makes written objection to Buyer within thirty (30) days after 
the Buyer mails the accounting to Seller.

     3.5  REFUND TO SELLER.  Provided that there does not then exist an Event 
of Default or any event or condition that with notice, lapse of time or 
otherwise would constitute an Event of Default, Buyer shall refund to Seller 
by check after the Reconciliation Date, the amount, if any, which Buyer owes 
to Seller at the end of the Reconciliation Period according to the accounting 
prepared by Buyer for that Reconciliation Period (the "Refund"). The Refund 
shall be an amount equal to:

          (A) (1)  The Reserve as of the beginning of that Reconciliation 
                   Period, PLUS
              (2)  the Reserve created for each Purchased Receivable purchased 
                   during that Reconciliation Period, 
              MINUS
          (B) The total for that Reconciliation Period of:
              (1)  the Administrative Fee;
              (2)  Finance Charges;
              (3)  Adjustments;
              (4)  Repurchase Amounts, to the extent Buyer has agreed to 
                   accept payment thereof by deduction from the Refund;
              (5)  the Reserve for the Account Balance as of the first day of 
                   the following Reconciliation Period in the minimum 
                   percentage set forth in Section 2.4 hereof; and
              (6)  all amounts due, including professional fees and expenses, 
as set forth in Section 12 for which oral or written demand has been made by 
Buyer to Seller during that Reconciliation Period to the extent Buyer has 
agreed to accept payment thereof by deduction from the Refund.

In the event the formula set forth in this Section 3.5 results in an amount 
due to Buyer from Seller, Seller shall make such payment in the same manner 
as set forth in Section 4.3 hereof for repurchases. If the formula set forth 
in this Section 3.5 results in an amount due to Seller from Buyer, Buyer 
shall make such payment by check, subject to Buyer's rights under Section 4.3 
and Buyer's rights of offset and recoupment.

4.   RECOURSE AND REPURCHASE OBLIGATIONS.

     4.1  RECOURSE.  Buyer's acquisition of Purchased Receivables from Seller 
shall be with full recourse against Seller. In the event the Obligations 
exceed the amount of Purchased Receivables and Collateral, Seller shall be 
liable for any deficiency.

     4.2  SELLER'S AGREEMENT TO REPURCHASE.  Seller agrees to pay to Buyer on 
demand, the full face amount, or any unpaid portion, of any Purchased 
Receivable:
          (A)  which remains unpaid ninety (90) calendar days after the 
          invoice date; or
          (B)  which is owned by any Account Debtor who has filed, or has had 
          filed against it, any bankruptcy case, assignment for the benefit 
          of creditors, receivership, or insolvency proceeding or who has 
          become insolvent (as defined in the United States Bankruptcy Code) 
          or who is generally not paying its debts as such debts become due; 
          or
          (C)  with respect to which there has been any breach of warranty or 
          representation set forth in Section 6 hereof or any breach of any 
          covenant contained in this Agreement; or
          (D)  with respect to which the Account Debtor asserts any discount, 
          allowance, return, dispute, counterclaim, offset, defense, right of 
          recoupment, right of return, warranty claim, or short payment;
together with all reasonable attorneys' and professional fees and expenses 
and all court costs incurred by Buyer in collecting such Purchased Receivable 
and/or enforcing its rights under, or collecting amounts owed by Seller in 
connection with, this Agreement (collectively, the "Repurchase Amount").

     4.3  SELLER'S PAYMENT OF THE REPURCHASE AMOUNT OR OTHER AMOUNTS DUE 
BUYER.  When any Repurchase Amount or other amount owing to Buyer becomes
due, Buyer shall inform Seller of the manner of payment which may be any one 
or more of the following in Buyer's sole discretion: (a) in cash immediately 
upon demand therefor; (b) by delivery of substitute invoices and an Invoice 
Transmittal acceptable to Buyer which shall thereupon become Purchased 
Receivables; (c) by adjustment to


                                                               Page 2 of 6

<PAGE>

the Reserve pursuant to Section 3.5 hereof; (d) by deduction from or offset 
against the Refund that would otherwise be due and payable to Seller; (e) by 
deduction from or offset against the amount that otherwise would be forwarded 
to Seller in respect of any further Advances that may be made by Buyer; or 
(f) by any combination of the foregoing as Buyer may from time to time choose.

     4.4  SELLER'S AGREEMENT TO REPURCHASE ALL PURCHASED RECEIVABLES.  Upon 
and after the occurrence of an Event of Default, Seller shall, upon Buyer's 
demand (or, in the case of an Event of Default under Section 9(B), 
immediately without notice or demand from Buyer) repurchase all the Purchased 
Receivables then outstanding, or such portion thereof as Buyer may demand. 
Such demand may, at Buyer's option, include and Seller shall pay to Buyer 
immediately upon demand, cash in an amount equal to the Advance with respect 
to each Purchased Receivable then outstanding together with all accrued 
Finance Charges, Adjustments, Administrative Fees, attorney's and professional 
fees, court costs and expenses as provided for herein, and any other 
Obligations. Upon receipt of payment in full of the Obligations, Buyer shall 
immediately instruct Account Debtors to pay Seller directly, and return to 
Seller any Refund due to Seller. For the purpose of calculating any Refund 
due under this Section only, the Reconciliation Date shall be deemed to be 
the date Buyer receives payment in good funds of all the Obligations as 
provided in this Section 4.4.

5.   POWER OF ATTORNEY.  Seller does hereby irrevocably appoint Buyer and its 
successors and assigns as Seller's true and lawful attorney in fact, and 
hereby authorizes Buyer, regardless of whether there has been an Event of 
Default, (a) to sell, assign, transfer, pledge, compromise, or discharge the 
whole or any part of the Purchased Receivables; (b) to demand, collect, 
receive, sue, and give releases to any Account Debtor for the monies due or 
which may become due upon or with respect to the Purchased Receivables and to 
compromise, prosecute, or defend any action, claim, case or proceeding 
relating to the Purchased Receivables, including the filing of a claim or the 
voting of such claims in any bankruptcy case, all in Buyer's name or Seller's 
name, as Buyer may choose; (c) to prepare, file and sign Seller's name on any 
notice, claim, assignment, demand, draft, or notice of or satisfaction of 
lien or mechanics' lien or similar document with respect to Purchased 
Receivables; (d) to notify all Account Debtors with respect to the Purchased 
Receivables to pay Buyer directly; (e) to receive, open, and dispose of all 
mail addressed to Seller for the purpose of collecting the Purchased 
Receivables; (f) to endorse Seller's name on any checks or other forms of 
payment on the Purchased Receivables; (g) to execute on behalf of Seller any 
and all instruments, documents, financing statements and the like to perfect 
Buyer's interests in the Purchased Receivables and Collateral; and (h) to do 
all acts and things necessary or expedient, in furtherance of any such 
purposes. If Buyer receives a check or item which is payment for both a 
Purchased Receivable and another receivable, the funds shall first be applied 
to the Purchased Receivable and, so long as there does not exist an Event of 
Default or an event that with notice, lapse of time or otherwise would 
constitute an Event of Default, the excess shall be remitted to Seller. Upon 
the occurrence and continuation of an Event of Default, all of the power of 
attorney rights granted by Seller to Buyer hereunder shall be applicable with 
respect to all Purchased Receivables and all Collateral.

to each Invoice Transmittal delivered to Buyer and each receivable described 
therein, that:
          (A)  Seller is the absolute owner of each receivable set forth

          transfer and assign such receivables;

          Invoice Transmittal and is not in dispute;

          fulfillment of any obligation or contract, past or future and any 
          and all obligations required of the Seller have been fulfilled as 
          of the date of the Invoice Transmittal;
          (D)  Each receivable set forth on the Invoice Transmittal is based

          in default, has not been previously sold, assigned, transferred, or 
          pledged, and is free of any and all liens, security interests and

          and shall be collected by Buyer, but if for any reason it should be 
          paid to Seller, Seller shall promptly notify Buyer of such payment, 
          shall hold any checks, drafts, or monies so received in trust for 
          the benefit of Buyer, and shall promptly transfer and deliver the 
          same to the Buyer;
          (G)  Buyer shall have the right of endorsement, and also the right

          petition for relief under the United States Bankruptcy Code;
          (I)  Each Account Debtor named on the Invoice Transmittal will not 
          object to the payment for, or the quality or the quantity of the

          forth on the Invoice Transmittal;
          (J)  Each Account Debtor shall promptly be notified, after 
          acceptance by Buyer, that the Purchased Receivable has been 
          transferred to and is payable to Buyer, and seller shall not take 
          or permit any action to countermand such notification; and
          (K)  All receivables forwarded to and accepted by Buyer after the 
          date hereof, and thereby becoming Purchased Receivables, shall 
          comply with each and every one of the foregoing representations, 
          warranties, covenants and agreements referred to above in this 
          Section 6.1.

          prior written notice if such name, organization, chief executive 
          office or other locations of Collateral or records concerning 
          Purchased Receivables or Collateral is changed or added and shall 
          execute any documents necessary to perfect Buyer's interest in the

          Invoice Transmittal, or as of the time Seller accepts any Advance

          States Bankruptcy Code or had filed against it an involuntary 
          petition for relief;
          (E)  If Seller owns, holds or has any interest in, any copyrights 
          (whether registered, or unregistered), patents or trademarks, and 
          licenses of any of the foregoing, such interest has been disclosed 
          to Buyer and is specifically listed and identified on a schedule to 
          this Agreement, and seller shall immediately notify Buyer if Seller 
          hereafter obtains any interest in any additional copyrights, 
          patents, trademarks or licenses that are significant in value or 
          are material to the conduct of its business; and 
          (F)  Seller shall provide Buyer with a Compliance Certificate (i) 
          on a quarterly basis to be received by Buyer no later than the 
          fifth calendar day following each calendar quarter, and; (ii) on a 
          more frequent or other basis if and as requested by Buyer.

7.   ADJUSTMENTS.  In the event of a breach of any of the representations, 
warranties, or covenants set forth in Section 6.1, or in the event any 
Adjustment or dispute is asserted by any Account Debtor, Seller shall 
promptly advise Buyer and shall, subject to the Buyer's approval, resolve 
such disputes and advise Buyer of any adjustments. Unless the disputed 
Purchased Receivable is repurchased by Seller and the full Repurchase Amount 
is paid, Buyer shall remain the absolute owner of any Purchased Receivable 
which is subject to Adjustment or repurchase under Section 4.2 hereof, and 
any rejected, returned, or recovered personal property, with the right to 
take possession thereof at any time. If such possession is not taken by 
Buyer, Seller is to resell it for Buyer's account at Seller's expense with 
the proceeds made payable to Buyer. While Seller retains possession of said 
returned goods, Seller shall segregate said goods and mark them "property of 
Silicon Valley Financial Services."

8.   SECURITY INTEREST.  To secure the prompt payment and performance to 
Buyer of all of the Obligations, Seller hereby grants to Buyer a continuing 
lien upon and security interest in all of Seller's now existing or hereafter 
arising rights and interest in the following, whether now owned or existing 
or hereafter created, acquired, or arising, and wherever located

          claim and delivery, reclamation, and stoppage in transit;
          (C)  All monies, refunds and other amounts due Seller, including, 
          without limitation, amounts due Seller under this Agreement 
          (including Seller's right of offset and recoupment);
          (D)  All equipment, machinery, furniture, furnishings, fixtures,

sale of finished inventory in the Seller's usual course of business. Seller 
agrees to sign UCC financing statements, in a form acceptable to Buyer, and 
any other instruments and documents requested by Buyer to evidence, perfect, 
or protect the interests of Buyer in the Collateral. Seller agrees to deliver 
to Buyer the originals of all instruments, chattel paper and documents 
evidencing or related to Purchased Receivables and Collateral.

9.    DEFAULT.  The occurrence of any one or more of the following shall 
constitute an Event of Default hereunder.
          (A)  Seller fails to pay any amount owed to Buyer as and when due;
          (B)  There shall be commenced by or against Seller any voluntary or 
          involuntary case under the United States Bankruptcy Code, or any 
          assignment for the benefit of creditors, or appointment of a 
          receiver or custodian for any of its assets; 
          (C)  Seller shall become insolvent in that its debts are greater 
          than the fair value of its assets, or Seller is generally not 
          paying its debts as they become due or is left with unreasonably 
          small capital;
          (D)  Any involuntary lien, garnishment, attachment or the like is

          Collateral;
          (E)  Seller shall breach any covenant, agreement, warranty, or 
          representation set forth herein, and the same is not cured to

          Seller oral or written notice thereof; provided, that if such 
          breach is incapable of being cured it shall constitute an immediate 
          default hereunder;

          now or hereafter existing, in favor of Buyer or any division or 
          affiliate of Silicon Valley Bank, regardless of whether such debt, 
          obligation or liability is direct or indirect, primary or 
          secondary, joint, several or joint and several, or fixed or 
          contingent, together with any and all renewals and extensions of 
          such debts, obligations and liabilities, or any part thereof;
          (G)  An event of default shall occur under any guaranty executed by 
          any guarantor of the Obligations of Seller to Buyer under this 
          Agreement, or any material provision of any such guaranty shall for 
          any reason cease to be valid or enforceable or any such guaranty 
          shall be repudiated or terminated, including by operation of law;
          (H)  A default or event of default shall occur under any agreement 
          between Seller and any creditor of Seller that has entered into a 
          subordination agreement with Buyer; or
          (I)  Any creditor that has entered into a subordination agreement 
          with Buyer shall breach any of the terms of or not comply with such 
          subordination agreement.

10.   REMEDIES UPON DEFAULT.  Upon the occurrence of an Event of Default, (1) 
without implying any obligation to buy receivables, Buyer may cease buying 
receivables or extending any financial accommodations to Seller; (2) all or a 
portion of the Obligations shall be, at the option of and upon demand by 
Buyer, or with respect to an Event of Default described in Section 9(B), 
automatically and without notice or demand, due and payable in full; and (3) 
Buyer shall have and may exercise all the rights and remedies under this 
Agreement and under applicable law, including the rights and remedies of a 
secured party under the California Uniform Commercial Code, all the power of 
attorney rights described in Section 5 with respect to all Collateral, and 
the right to collect, dispose of, sell, lease, use, and realize upon all 
Purchased Receivables and all Collateral in any commercial reasonable manner. 
Seller and Buyer agree that any notice of sale required to be given to Seller 
shall be deemed

                                                                 Page 4 of 6

<PAGE>

to be reasonable if given five (5) days prior to the date on or after which 
the sale may be held. In the event that the Obligations are accelerated 
hereunder, Seller shall repurchase all of the Purchased Receivables as set 
forth in Section 4.4.

11.     ACCRUAL OF INTEREST.  If any amount owed by Seller hereunder is not 
paid when due, including, without limitation, amounts due under Section 3.5, 
Repurchase Amounts, amounts due under Section 12, and any other Obligations, 
such amounts shall bear interest at a per annum rate equal to the per annum 
rate of the Finance Charges until the earlier of (i) payment in good funds or 
(ii) entry of a final judgment thereof, at which time the principal amount of 
any money judgment remaining unsatisfied shall accrue interest at the highest 
rated allowed by applicable law.

12.     FEES, COSTS AND EXPENSES; INDEMNIFICATION.  The Seller will pay to 
Buyer immediately upon demand all fees, costs and expenses (including fees of 
attorneys and professionals and their costs and expenses) that Buyer incurs 
or may from time to time impose in connection with any of the following: (a) 
preparing, negotiating, administering, and enforcing this Agreement or any 
other agreement executed in connection herewith, including any amendments, 
waivers or consents in connection with any of the foregoing, (b) any 
litigation or dispute (whether instituted by Buyer, Seller or any other 
person) in any way relating to the Purchased Receivables, the Collateral, 
this Agreement or any other agreement executed in connection herewith or 
therewith, (d) enforcing any rights against Seller or any guarantor, or any 
Account Debtor, (e) protecting or enforcing its interest in the Purchased 
Receivables or the Collateral, (f) collecting the Purchased Receivables and 
the Obligations, and (g) the representation of Buyer in connection with any 
bankruptcy case or insolvency proceeding involving Seller, any Purchased 
Receivable, the Collateral, any Account Debtor, or any guarantor. Seller 
shall indemnify and hold Buyer harmless from and against any and all 
claims, actions, damages, costs, expenses, and liabilities of any nature 
whatsoever arising in connection with any of the foregoing.

13.     SEVERABILITY, WAIVER, AND CHOICE OF LAW.  In the event that any 
provision of this Agreement is deemed invalid by reason of law, this 
Agreement will be construed as not containing such provision and the 
remainder of the Agreement shall remain in full force and effect. Buyer 
retains all of its rights, even if it makes an Advance after a default. If 
Buyer waives a default, it may enforce a later default. Any consent or waiver 
under, or amendment of, this Agreement must be in writing. Nothing contained 
herein, or any action taken or not taken by Buyer at any time, shall be 
construed at any time to be indicative of any obligation or willingness on 
the part of Buyer to amend this Agreement or to grant to Seller any waivers 
or consents. This Agreement has been transmitted by Seller to Buyer at 
Buyer's office in the State of California and has been executed and accepted 
by Buyer in the State of California. This Agreement shall be governed by and 
interpreted in accordance with the internal laws of the State of California.

14.     ACCOUNT COLLECTION SERVICES.  Certain Account Debtors may require or 
prefer that all of Seller's receivables be paid to the same address and/or 
party, or Seller and Buyer may agree that all receivables with respect to 
certain Account Debtors be paid to one party. In such event Buyer and Seller 
may agree that Buyer shall collect all receivables whether owned by Seller or 
Buyer and (provided that there does not then exist an Event of Default or 
event that with notice, lapse or time or otherwise would constitute an Event 
of Default, and subject to Buyer's rights in the Collateral) Buyer agrees to 
remit to Seller the amount of the receivables collections it receives with 
respect to receivables other than Purchased Receivables. It is understood and 
agreed by Seller that this Section does not impose any affirmative duty on 
Buyer to do any act other than to turn over such amounts. All such 
receivables and collections are Collateral and in the event of Seller's 
default hereunder, Buyer shall have no duty to remit collections of 
Collateral and may apply such collections to the obligations hereunder and 
Buyer shall have the rights of a secured party under the California Uniform 
Commercial Code.

15.     NOTICES.  All notices shall be given to Buyer and Seller at the 
addresses or faxes set forth on the first page of this Agreement and shall be 
deemed to have been delivered and received: (a) if mailed, three (3) calendar 
days after deposited in the United States mail, first class, postage 
pre-paid, (b) one (1) calendar day after deposit with an overnight mail or 
messenger service; or (c) on the same date of confirmed transmission if sent 
by hand delivery, telecopy, telefax or telex.

16.     JURY TRIAL.  SELLER AND BUYER EACH HEREBY (a) WAIVE THEIR RESPECTIVE 
RIGHTS TO A JURY TRIAL ON ANY CLAIM OR ACTION ARISING OUT OF OR IN CONNECTION 
WITH THIS AGREEMENT, ANY RELATED AGREEMENTS, OR ANY OF THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY; (b) RECOGNIZE AND AGREE THAT THE FOREGOING 
WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT; 
AND (c) REPRESENT AND WARRANT THAT IT HAS REVIEWED THIS WAIVER, HAS 
DETERMINED FOR ITSELF THE NECESSITY TO REVIEW THE SAME WITH ITS LEGAL 
COUNSEL, AND KNOWINGLY AND VOLUNTARILY WAIVES ALL RIGHTS TO A JURY TRIAL.

17.     TERM AND TERMINATION.  The term of this Agreement shall be for one 
(1) year from the date hereof, and from year to year thereafter unless 
terminated in writing by Buyer or Seller. Seller and Buyer shall each have 
the right to terminate this Agreement at any time. Notwithstanding the 
foregoing, any termination of this Agreement shall not affect Buyer's 
security interest in the Collateral and Buyer's ownership of the Purchased 
Receivables, and this Agreement shall continue to be effective, and Buyer's 
rights and remedies hereunder shall survive such termination, until all 
transactions entered into and Obligations incurred hereunder or in connection 
herewith have been completed and satisfied in full.

18.     TITLES AND SECTION HEADINGS.  The titles and section headings used 
herein are for convenience only and shall not be used in interpreting this 
Agreement.


                                                                     Page 5 of 6
<PAGE>


19.     OTHER AGREEMENTS.  The terms and provisions of this Agreement shall 
not adversely affect the rights of Buyer or any other division or affiliate of 
Silicon Valley Bank under any other document, instrument or agreement. The 
terms of such other documents, instruments and agreements shall remain in 
full force and effect notwithstanding the execution of this Agreement. In the 
event of a conflict between any provision of this Agreement and any provision 
of any other document, instrument or agreement between Seller on the one hand,
and Buyer or any other division or affiliate of Silicon Valley Bank on the 
other hand, Buyer shall determine in its sole discretion which provision 
shall apply. Seller acknowledges specifically that any security agreements, 
liens and/or security interests currently securing payment of any obligations 
of Seller owing to Buyer or any other division or affiliate of Silicon Valley 
Bank also secure Seller's obligations under this Agreement, and are valid and 
subsisting and are not adversely affected by execution of this Agreement. 
Seller further acknowledges that (a) any collateral under other outstanding 
security agreements or other documents between Seller and Buyer or any other 
division or affiliate of Silicon Valley Bank secures the obligations of Seller 
under this Agreement and (b) a default by Seller under this Agreement 
constitutes a default under other outstanding agreements between Seller and 
Buyer or any other division or affiliate of Silicon Valley Bank.

     IN WITNESS WHEREOF, Seller and Buyer have executed this Agreement on the 
day and year above written.

The Schedule to this Agreement (the "Schedule") shall for all purposes be deemed
to be a part of this Agreement, and the same is an integral part of this
Agreement.  (Definitions of certain terms used in this Agreement are set forth
in Section 8 below.) 

          1.   LOANS.

          1.1  LOANS.  Coast will make loans to Borrower (the "Loans"), in

"Credit Limit") shown on the Schedule, provided no Default or Event of Default
has occurred and is continuing.    

          1.2  INTEREST.  All Loans and all other monetary Obligations shall
bear interest at the rate shown on the Schedule, except where expressly set
forth to the contrary in this Agreement.  Interest shall be payable monthly, on
the last day of the month.  Interest may, in Coast's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans.  Regardless of the amount of Obligations that may be
outstanding from time to time, Borrower shall pay Coast minimum monthly interest
during the term of this Agreement with respect to the Receivable Loans in the
amount set forth on the Schedule (the "Minimum Monthly Interest").

          1.3  FEES.  Borrower shall pay Coast the fee(s) shown on the Schedule,
which are in addition to all interest and other sums payable to Coast and are
not refundable. 

          2.   SECURITY INTEREST.

          2.1  SECURITY INTEREST.  To secure the payment and performance of all
of the Obligations when due, Borrower hereby grants to Coast a security interest
in all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located:  All Receivables, Inventory, Equipment, and
General Intangibles, including, without limitation, all of Borrower's Deposit
Accounts, and all money, and all property now or at any time in the future in
Coast's possession (including claims and credit balances), and all proceeds of
any of the foregoing (including proceeds of any insurance policies, proceeds of
proceeds, and claims against third parties), all products of any of the
foregoing, and all books and records related to any of the foregoing (all of the
foregoing, together with all other property in which Coast may now or in the
future be granted a lien or security interest, is referred to herein,
collectively, as the "Collateral").

          3.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

          In order to induce Coast to enter into this Agreement and to make 
Loans, Borrower represents and warrants to Coast as follows, and Borrower 
covenants that the following representations will continue to be true, 


<PAGE>

     LOAN AND SECURITY AGREEMENT                         COAST BUSINESS CREDIT
- -------------------------------------------------------------------------



and that Borrower will at all times comply with all of the following 
covenants:

          3.1  CORPORATE EXISTENCE AND AUTHORITY.  Borrower, if a corporation,
is and will continue to be, duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation.  Borrower is
and will continue to be qualified and licensed to do business in all
jurisdictions in which any failure to do so would have a material adverse effect
on Borrower.  The execution, delivery and performance by Borrower of this
Agreement, and all other documents contemplated hereby (i) have been duly and
validly authorized, (ii) are enforceable against Borrower in accordance with
their terms (except as enforcement may be limited by equitable principles and by
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
creditors' rights generally), and (iii) do not violate Borrower's articles or
certificate of incorporation, or Borrower's by-laws, or any law or any material
agreement or instrument which is binding upon Borrower or its property, and (iv)
do not constitute grounds for acceleration of any material indebtedness or
obligation under any material agreement or instrument which is binding upon
Borrower or its property.

          3.2  NAME; TRADE NAMES AND STYLES.  The name of Borrower set forth in
the heading to this Agreement is its correct name.  Listed on the Schedule are
all prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Coast 30 days' prior written notice before changing its name
or doing business under any other name.  Borrower has complied, and will in the
future comply, with all laws relating to the conduct of business under a
fictitious business name.

          3.3  PLACE OF BUSINESS; LOCATION OF COLLATERAL.  The address set forth
in the heading to this Agreement is Borrower's chief executive office.  In
addition, Borrower has places of business and Collateral is located only at the
locations set forth on the Schedule.  Borrower will give Coast at least 30 days
prior written notice before opening any additional place of business, changing
its chief executive office, or moving any of the Collateral to a location other
than Borrower's Address or one of the locations set forth on the Schedule.

          3.4  TITLE TO COLLATERAL; PERMITTED LIENS.  Borrower is now, and will
at all times in the future be, the sole owner of all the Collateral, except for
items of Equipment which are leased by Borrower.  The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens.  Coast now has, and
will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Coast and the Collateral against all claims of
others.  None of the Collateral now is or will be affixed to any real property
in such a manner, or with such intent, as to become a fixture.  Borrower is not
and will not become a lessee under any real property lease pursuant to which the
lessor may obtain any rights in any of the Collateral and no such lease now
prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's
right to remove any Collateral from the leased premises.  Whenever any
Collateral is located upon premises in which any third party has an interest
(whether as owner, mortgagee, beneficiary under a deed of trust, lien or
otherwise), Borrower shall, whenever requested by Coast, use its best efforts to
cause such third party to execute and deliver to Coast, in form acceptable to
Coast, such waivers and subordinations as Coast shall specify, so as to ensure
that Coast's rights in the Collateral are, and will continue to be, superior to
the rights of any such third party.  Borrower will keep in full force and
effect, and will comply with all the terms of, any lease of real property where
any of the Collateral now or in the future may be located.

          3.5  MAINTENANCE OF COLLATERAL.  Borrower will maintain the Collateral
in good working condition, and Borrower will not use the Collateral for any
unlawful purpose.  Borrower will immediately advise Coast in writing of any
material loss or damage to the Collateral.

          3.6  BOOKS AND RECORDS.  Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

          3.7  FINANCIAL CONDITION, STATEMENTS AND REPORTS.  All financial
statements now or in the future delivered to Coast have been, and will be,
prepared in conformity with generally accepted accounting principles (except, in
the case of unaudited financial statements, for the absence of footnotes and
subject to normal year-end adjustments) and now and in the future will fairly
reflect the financial condition of Borrower, at the times and for the periods
therein stated.  Between the last date covered by any such statement provided to
Coast and the date hereof, there has been no material adverse change in the
financial condition or business of Borrower.  Borrower is now and will continue
to be solvent.     

          3.8  TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS.  Borrower has 
timely filed, and will timely file, all tax returns and reports required by 
foreign, federal, state and local law, and Borrower has 

                                       2

<PAGE>

     LOAN AND SECURITY AGREEMENT                         COAST BUSINESS CREDIT
- -------------------------------------------------------------------------



timely paid, and will timely pay, all foreign, federal, state and local 
taxes, assessments, deposits and contributions now or in the future owed by 
Borrower.  Borrower may, however, defer payment of any contested taxes, 
provided that Borrower (i) in good faith contests Borrower's obligation to 
pay the taxes by appropriate proceedings promptly and diligently instituted 
and conducted, (ii) notifies Coast in writing of the commencement of, and any 
material development in, the proceedings, and (iii) posts bonds or takes any 
other steps required to keep the contested taxes from becoming a lien upon 
any of the Collateral.  As of the date hereof, Borrower is unaware of any 
claims or adjustments proposed for any of Borrower's prior tax years which 
could result in additional taxes becoming due and payable by Borrower.  
Borrower has paid, and shall continue to pay all amounts necessary to fund 
all present and future pension, profit sharing and deferred compensation 
plans in accordance with their terms, and Borrower has not and will not 
withdraw from participation in, permit partial or complete termination of, or 
permit the occurrence of any other event with respect to, any such plan which 
could result in any liability of Borrower, including any liability to the 
Pension Benefit Guaranty Corporation or its successors or any other 
governmental agency. Borrower shall, at all times, utilize the services of an 
outside payroll service providing for the automatic deposit of all payroll 
taxes payable by Borrower.  

          3.9  COMPLIANCE WITH LAW.  Borrower has complied, and will comply, in
all material respects, with all provisions of all material foreign, federal,
state and local laws and regulations relating to Borrower, including, but not
limited to, those relating to Borrower's ownership of real or personal property,
the conduct and licensing of Borrower's business, and environmental matters.

          3.10  LITIGATION.  Except as disclosed in the Schedule, there is no
claim, suit, litigation, proceeding or investigation pending or (to best of
Borrower's knowledge) threatened by or against or affecting Borrower in any
court or before any governmental agency (or any basis therefor known to
Borrower) which may result, either separately or in the aggregate, in any
material adverse change in the financial condition or business of Borrower, or
in any material impairment in the ability of Borrower to carry on its business
in substantially the same manner as it is now being conducted.  Borrower will
promptly inform Coast in writing of any claim, proceeding, litigation or
investigation in the future threatened or instituted by or against Borrower
involving any single claim of Fifty Thousand Dollars ($50,000.00) or more, or
involving One Hundred Thousand Dollars ($100,000.00) or more in the aggregate.

          3.11  USE OF PROCEEDS.  All proceeds of all Loans shall be used solely
for lawful business purposes.  Borrower is not purchasing or carrying any
"margin stock" (as defined in Regulation G of the Board of Governors of the
Federal Reserve System) and no part of the proceeds of any Loan will be used to
purchase or carry any "margin stock" or to extend credit to others for the
purpose of purchasing or carrying any "margin stock." 

          4.   RECEIVABLES.

          4.1  REPRESENTATIONS RELATING TO RECEIVABLES.  Borrower represents and
warrants to Coast as follows:  Each Receivable with respect to which Loans are
requested by Borrower shall, on the date each Loan is requested and made,
represent an undisputed bona fide existing unconditional obligation of the
Account Debtor created by the sale, delivery, and acceptance of goods or the
rendition of services in the ordinary course of Borrower's business.

          4.2  REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE. 
Borrower represents and warrants to Coast as follows:  All statements made and
all unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be. 
All sales and other transactions underlying or giving rise to each Receivable
shall fully comply with all applicable laws and governmental rules and
regulations.  All signatures and indorsements on all documents, instruments, and
agreements relating to all Receivables are and shall be genuine, and all such
documents, instruments and agreements are and shall be legally enforceable in
accordance with their terms.

          4.3  SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES.  Borrower shall
deliver to Coast transaction reports and loan requests, schedules of
Receivables, and schedules of collections, all on Coast's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Coast's security interest and other rights in all of
Borrower's Receivables, nor shall Coast's failure to advance or lend against a
specific Receivable affect or limit Coast's security interest and other rights
therein.  Loan requests received after 10:30 AM will not be considered by Coast
until the next Business Day.  Together with each such schedule, or later if
requested by Coast, Borrower shall furnish Coast with copies (or, at Coast's

                                       3

<PAGE>

     LOAN AND SECURITY AGREEMENT                         COAST BUSINESS CREDIT
- -------------------------------------------------------------------------



request, originals) of all contracts, orders, invoices, and other similar
documents, and all original shipping instructions, delivery receipts, bills of
lading, and other evidence of delivery, for any goods the sale or disposition of
which gave rise to such Receivables, and Borrower warrants the genuineness of
all of the foregoing.  Borrower shall also furnish to Coast an aged accounts
receivable trial balance in such form and at such intervals as Coast shall 
request.  In addition, Borrower shall deliver to Coast, upon Coast's request,
the originals of all instruments, chattel paper, security agreements, guarantees
and other documents and property evidencing or securing any Receivables, upon
receipt thereof and in the same form as received, with all necessary
indorsements, all of which shall be with recourse.  Borrower shall also provide
Coast with copies of all credit memos as and when requested by Coast.

          4.4  COLLECTION OF RECEIVABLES.  Borrower shall have the right to
collect all Receivables, unless and until an Event of Default has occurred. 
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Coast, and Borrower shall deliver all such payments and proceeds to Coast within
one Business Day after receipt by Borrower, in their original form, duly
endorsed to Coast, to be applied to the Obligations in such order as Coast shall
determine.  Coast may, in its discretion, require that all proceeds of
Collateral be deposited by Borrower into a lockbox account, or such other
"blocked account" as Coast may specify, pursuant to a blocked account agreement
in such form as Coast may specify.  Coast or its designee may, at any time with
prior notice to Borrower notify Account Debtors that Coast has been granted a
security interest in the Receivables.      

          4.5. REMITTANCE OF PROCEEDS.  All proceeds arising from the
disposition of any Collateral shall be delivered to Coast within one Business
Day after receipt by Borrower, in their original form, duly endorsed to Coast,
to be applied to the Obligations in such order as Coast shall determine. 
Borrower agrees that it will not commingle proceeds of Collateral with any of
Borrower's other funds or property, but will hold such proceeds separate and
apart from such other funds and property and in  a constructive trust for Coast.
Nothing in this Section limits the restrictions on disposition of Collateral set
forth elsewhere in this Agreement.

          4.6  DISPUTES.  Borrower shall notify Coast promptly of all disputes
or claims relating to Receivables.  Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in full,
or agree to do any of the foregoing, except that Borrower may do so, provided
that: (i) Borrower does so in good faith, in a commercially reasonable manner,
in the ordinary course of business, and in arm's length transactions, which are
reported to Coast on the regular reports provided to Coast; (ii) no Default or
Event of Default has occurred and is continuing; and (iii) taking into account
all such discounts settlements and forgiveness, the total outstanding Loans will
not exceed the Credit Limit.  Coast may, at any time after the occurrence of an
Event of Default, settle or adjust disputes or claims directly with Account
Debtors for amounts and upon terms which Coast considers advisable in its
reasonable credit judgment and, in all cases, Coast shall credit Borrower's Loan
account with only the net amounts received by Coast in payment of any
Receivables.

          4.7  RETURNS.  Provided no Event of Default has occurred and is
continuing, if any Account Debtor returns any Inventory to Borrower in the
ordinary course of its business, Borrower shall promptly determine the reason
for such return and promptly issue a credit memorandum to the Account Debtor in
the appropriate amount.  In the event any attempted return occurs after the
occurrence of any Event of Default, Borrower shall (i) hold the returned
Inventory in trust for Coast, (ii) segregate all returned Inventory from all of
Borrower's other property, (iii) conspicuously label the returned Inventory as
subject to Coast's security interest, and (iv) immediately notify Coast of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Coast's request deliver such
returned Inventory to Coast.  

          4.8  VERIFICATION.  Coast may, from time to time, verify directly with
the respective Account Debtors the validity, amount and other matters relating
to the Receivables, by means of mail, telephone or otherwise, either in the name
of Borrower or Coast or such other name as Coast may choose. 

          4.9  NO LIABILITY.  Coast shall not under any circumstances be
responsible or liable for any shortage or discrepancy in, damage to, or loss or
destruction of, any goods, the sale or other disposition of which gives rise to
a Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Coast be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable.  Nothing herein shall, however, relieve Coast from liability for its
own  negligence or willful misconduct.

          5.   ADDITIONAL DUTIES OF THE BORROWER.

comply with the financial and other covenants set forth in the Schedule.

          5.2  INSURANCE.  Borrower shall, at all times insure all of the
tangible personal property Collateral and carry such other business insurance,
with insurers reasonably acceptable to Coast, in such form and amounts as Coast
may reasonably require, and Borrower shall provide evidence of such insurance to
Coast, so that Coast is satisfied that such insurance is, at all times, in full
force and effect.  All liability insurance policies of Borrower shall name Coast
as an additional insured, and all property casualty and related insurance
policies of Borrower shall name Coast as a loss payee thereon and Borrower shall
cause a lenders loss payee endorsement in form reasonably acceptable to Coast. 
Upon receipt of the proceeds of any such insurance, Coast shall apply such
proceeds in reduction of the Obligations as Coast shall determine in its sole
discretion, except that, provided no Default or Event of Default has occurred
and is continuing, Coast shall release to Borrower insurance proceeds with
respect to Equipment and Inventory totaling less than Fifty Thousand Dollars
($50,000.00), which shall be utilized by Borrower for the replacement of the
Equipment with respect to which the insurance proceeds were paid.  Coast may
require reasonable assurance that the insurance proceeds so released will be so
used.  If Borrower fails to provide or pay for any insurance, Coast may, but is
not obligated to, obtain the same at Borrower's expense.  Borrower shall
promptly deliver to Coast copies of all reports made to insurance companies.

          5.3  REPORTS.  Borrower, at its expense, shall provide Coast with the
written reports set forth in the Schedule, and such other written reports with

other financial documentation), as Coast shall from time to time reasonably
specify.

          5.4  ACCESS TO COLLATERAL, BOOKS AND RECORDS.  At reasonable times,
and on one Business Day's notice, Coast, or its agents, shall have the right to
inspect, audit and copy Borrower's books and records and the Collateral (the
"Audits").  Coast shall take reasonable steps to keep confidential all
confidential information obtained in any Audit, but Coast shall have the right
to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process.  The Audits
shall be at Borrower's expense and the charge for the Audits shall be Seven
Hundred Fifty Dollars ($750.00)  per person per day (or such higher amount as
shall represent Coast's then current standard charge for the same), plus
reasonable out of pocket expenses.  Borrower will not enter into any agreement
with any accounting firm, service bureau or third party to store Borrower's
books or records at any location other than Borrower's Address, without first
notifying Coast of the same and obtaining the written agreement from such
accounting firm, service bureau or other third party to give Coast the same
rights with respect to access to books and records and related rights as Coast
has under this Loan Agreement.    

          5.5  NEGATIVE COVENANTS.  Borrower shall not, without Coast's prior
written consent, do any of the following:  

    (i)  merge or consolidate with another corporation or entity, except in a
transaction in which (A) the shareholders of the Borrower hold at least 50% of
the common stock and all other capital stock of the surviving corporation
immediately after such merger or consolidation, and (B) the Borrower is the
surviving corporation; 

    (ii) acquire any assets, except (A) in the ordinary course of business, or

    (xi) redeem, retire, purchase or otherwise acquire, directly or indirectly,
any of Borrower's stock, except that Borrower may repurchase stock owned by

material adverse effect on Borrower or on the prospect of repayment of the

transaction.

proceeding be instituted by or against Coast with respect to any Collateral or
relating to Borrower, Borrower shall, without expense to Coast, make available

prosecute or defend any such suit or proceeding.

          5.7  INDEMNITY.  Borrower hereby agrees to indemnify Coast and hold
Coast harmless from and against any and all claims, debts, liabilities, demands,
obligations, actions, causes of action, penalties, reasonable costs and expenses

description, which Coast may sustain or incur based upon or arising out of any
of the Obligations, any actual or alleged failure to collect and pay over any
withholding or other tax relating to Borrower or its employees, any relationship
or agreement between Coast and Borrower, any actual or alleged failure of Coast
to comply with any writ of attachment or other legal process relating to
Borrower or any of its property, or any other matter, cause or thing whatsoever
occurred, done, omitted or suffered to be done by Coast relating to Borrower or
the Obligations (except any such amounts sustained or incurred as the result of
the  negligence or willful misconduct of Coast).  Notwithstanding any provision
in this Agreement to the contrary, the indemnity agreement set forth in this
Section shall survive any termination of this Agreement and shall for all
purposes continue in full force and effect. 

          5.8  FURTHER ASSURANCES.  Borrower agrees, at its expense, on request
by Coast, to execute all documents and take all actions, as Coast, may deem

          6.   TERM.

          6.1  MATURITY DATE.  This Agreement shall continue in effect until the
maturity date set forth on the Schedule (the "Maturity Date"); provided that the
Maturity Date shall automatically be extended, and this Agreement shall
automatically and continuously renew, for successive additional terms of one
year each, unless one party gives written notice to the other, not less than
sixty (60) days prior to the next Maturity Date, that such party elects to
terminate this Agreement effective on the next Maturity Date.  If this Agreement
is renewed under this Section 6.1, Borrower shall pay to Coast a renewal fee
(the "Renewal Fee") in the amount shown in the Schedule.  The Renewal Fee shall
be due and payable on the effective date of renewal and thereafter shall incur
interest at a rate equal to the rate applicable to the Receivable Loans.

          6.2  EARLY TERMINATION.  This Agreement may be terminated prior to the
Maturity Date as follows:  (i) by Borrower, effective three Business Days after
written notice of termination is given to Coast; or (ii) by Coast at any time
after the occurrence of an Event of Default, without notice, effective
immediately.  If this Agreement is terminated by Borrower or by Coast under this
Section 6.2, Borrower shall pay to Coast a termination fee (the "Early
Termination Fee") in the amount shown on the Schedule.  The Early Termination
Fee shall be due and payable on the effective date of termination and thereafter
shall bear interest at a rate equal to the rate applicable to the Receivable
Loans.

          6.3  PAYMENT OF OBLIGATIONS.  On the Maturity Date or on any 
earlier effective date of termination, Borrower shall pay and perform in full 
all Obligations, whether evidenced by installment notes or otherwise, and 
whether or not all or any part of such Obligations are otherwise then due and 
payable. Without limiting the generality of the foregoing, if on the Maturity 
Date,  or on any earlier effective date of termination, there are any 
outstanding Letters of Credit issued by Coast or issued by another 
institution based upon an application, 

                                       6

guarantee, indemnity or similar agreement on the part of Coast,
then on such date Borrower shall provide to Coast cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Coast's then
standard form cash pledge agreement.  Notwithstanding any termination of this
Agreement, all of Coast's security interests in all of the Collateral and all of
the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Coast, Coast may, in its sole discretion, refuse to make any further Loans after
termination.  No termination shall in any way affect or impair any right or
remedy of Coast, nor shall any such termination relieve Borrower of any
Obligation to Coast, until all of the Obligations have been paid and performed
in full.  Upon payment and performance in full of all the Obligations and
termination of this Agreement, Coast shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Coast's security interests.

          7.   EVENTS OF DEFAULT AND REMEDIES.

          (n)  Borrower makes any payment on account of any indebtedness or

his subordination agreement; or 

          (o)  There shall be a change in the record or beneficial ownership of
an aggregate of more than twenty percent (20%) of the outstanding shares of
stock of Borrower, in one or more transactions, compared to the ownership of
outstanding shares of stock of Borrower in effect on the date hereof, without
the prior written consent of Coast; or 

          (p)  Borrower shall generally not pay its debts as they become due, or
Borrower shall conceal, remove or transfer any part of its property, with intent

          (q)  There shall be a material adverse change in Borrower's business
or financial condition; or 

          (r)  Coast, acting in good faith and in a commercially reasonable
manner, deems itself insecure because of the occurrence of an event prior to the
effective date hereof of which Coast had no knowledge on the effective date or
because of the occurrence of an event on or subsequent to the effective date. 
Coast may cease making any Loans hereunder during any of the above cure periods,
and thereafter if an Event of Default has occurred.  

          7.2  REMEDIES.  Upon the occurrence, and during the continuance, of
any Event of Default, Coast, at its option, and without notice or demand of any
kind (all of which are hereby expressly waived by Borrower), may do any one or
more of the following: 

          (a)  Cease making Loans or otherwise extending credit to Borrower
under this Agreement or any other document or agreement; 

          (b)  Accelerate and declare all or any part of the Obligations to be
immediately due, payable, and performable, notwithstanding any deferred or
installment payments allowed by any instrument evidencing or relating to any
Obligation; 

          (c)  Take possession of any or all of the Collateral wherever it may
be found, and for that purpose Borrower hereby authorizes Coast without judicial
process to enter onto any of Borrower's premises without interference to search
for, take possession of, keep, store, or remove any of the Collateral, and
remain on the premises or cause a custodian to remain on the premises in
exclusive control thereof, without charge for so long as Coast deems it
reasonably necessary in order to complete the enforcement of its rights under
this Agreement or any other agreement; provided, however, that should Coast seek
to take possession of any of the Collateral by Court process, Borrower hereby
irrevocably waives: 

                    (i)  any bond and any surety or security relating thereto
     required by any statute, court rule or otherwise as an incident to such
     possession; 

                    (ii)  any demand for possession prior to the commencement of
     any suit or action to recover possession thereof; and 

                    (iii)  any requirement that Coast retain possession of, and
     not dispose of, any such Collateral until after trial or final judgment; 

          (d)  Require Borrower to assemble any or all of the Collateral and
make it available to Coast at places designated by Coast which are reasonably
convenient to Coast and Borrower, and to remove the Collateral to such locations
as Coast may deem advisable; 

          (e)  Complete the processing, manufacturing or repair of any
Collateral prior to a disposition thereof and, for such purpose and for the
purpose of removal, Coast shall have the right to use Borrower's premises,
vehicles, hoists, lifts, cranes, equipment and all other property without
charge; 

          (f)  Sell, lease or otherwise dispose of any of the Collateral, in 
its condition at the time Coast obtains possession of it or after further 
manufacturing, processing or repair, at one or more public and/or private 
sales, in lots or in bulk, for cash, exchange or other property, or on 
credit, and to adjourn any such sale from time to time without notice other 
than oral announcement at the time scheduled for sale.  Coast shall have the 
right to conduct such disposition on Borrower's premises without charge, for 
such time or times as Coast deems 

                                       8
<PAGE>

     LOAN AND SECURITY AGREEMENT                         COAST BUSINESS CREDIT
- -------------------------------------------------------------------------



reasonable, or on Coast's premises, or elsewhere and the Collateral need not 
be located at the place of disposition.  Coast may directly or through any 
affiliated company purchase or lease any Collateral at any such public 
disposition, and if permissible under applicable law, at any private 
disposition.  Any sale or other disposition of Collateral shall not relieve 
Borrower of any liability Borrower may have if any Collateral is defective as 
to title or physical condition or otherwise at the time of sale; 

          (g)  Demand payment of, and collect any Receivables and General
Intangibles comprising Collateral and, in connection therewith, Borrower
irrevocably authorizes Coast to endorse or sign Borrower's name on all
collections, receipts, instruments and other documents, to take possession of
and open mail addressed to Borrower and remove therefrom payments made with
respect to any item of the Collateral or proceeds thereof, and, in Coast's sole
discretion, to grant extensions of time to pay, compromise claims and settle
Receivables and the like for less than face value; 

          (h)  Offset against any sums in any of Borrower's general, special or
other Deposit Accounts with Coast; and 

          (i)  Demand and receive possession of any of Borrower's federal and
state income tax returns and the books and records utilized in the preparation
thereof or referring thereto.  All reasonable attorneys' fees, expenses, costs,
liabilities and obligations incurred by Coast with respect to the foregoing
shall be due from the Borrower to Coast on demand. Coast may charge the same to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as is applicable to the Receivable Loans.  Without limiting any of Coast's
rights and remedies, from and after the occurrence of any Event of Default, the
interest rate applicable to the Obligations shall be increased by an additional
three percent per annum.

          7.3  STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS.  Borrower
and Coast agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable:  

          (a)  Notice of the sale is given to Borrower at least seven (7) days
prior to the sale, and, in the case of a public sale, notice of the sale is
published at least seven (7) days before the sale in a newspaper of general
circulation in the county where the sale is to be conducted; 

          (b)  Notice of the sale describes the collateral in general, non-
specific terms; 

          (c)  The sale is conducted at a place designated by Coast, with or
without the Collateral being present; 

          (d)  The sale commences at any time between 8:00 a.m. and 6:00 p.m;  

          (e)  Payment of the purchase price in cash or by cashier's check or
wire transfer is required; 

          (f)  With respect to any sale of any of the Collateral, Coast may (but
is not obligated to) direct any prospective purchaser to ascertain directly from
Borrower any and all information concerning the same.  Coast shall be free to
employ other methods of noticing and selling the Collateral, in its discretion,
if they are commercially reasonable.

          7.4  POWER OF ATTORNEY.  Upon the occurrence, and during the
continuance, of any Event of Default, without limiting Coast's other rights and
remedies, Borrower grants to Coast an irrevocable power of attorney coupled with
an interest, authorizing and permitting Coast (acting through any of its
employees, attorneys or agents) at any time, at its option, but without
obligation, with or without notice to Borrower, and at Borrower's expense, to do
any or all of the following, in Borrower's name or otherwise, but Coast agrees
to exercise the following powers in a commercially reasonable manner:  

          (a)  Execute on behalf of Borrower any documents that Coast may, in
its sole discretion, deem advisable in order to perfect and maintain Coast's
security interest in the Collateral, or in order to exercise a right of Borrower
or Coast, or in order to fully consummate all the transactions contemplated
under this Agreement, and all other present and future agreements; 

          (b)  Execute on behalf of Borrower any document exercising,
transferring or assigning any option to purchase, sell or otherwise dispose of
or to lease (as lessor or lessee) any real or personal property which is part of
Coast's Collateral or in which Coast has an interest; 

          (c)  Execute on behalf of Borrower, any invoices relating to any 
Receivable, any draft against any Account Debtor and any notice to any 
Account Debtor, any proof of claim in bankruptcy, any Notice of Lien, claim 
of mechanic's, materialman's or other lien, or 

                                       9

- -------------------------------------------------------------------------



assignment or satisfaction of mechanic's, materialman's or other lien; 

          (d)  Take control in any manner of any cash or non-cash items of
payment or proceeds of Collateral; endorse the name of Borrower upon any
instruments, or documents, evidence of payment or Collateral that may come into
Coast's possession;

          (e)  Endorse all checks and other forms of remittances received by
Coast; 

          (f)  Pay, contest or settle any lien, charge, encumbrance, security
interest and adverse claim in or to any of the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same; 

          (g)  Grant extensions of time to pay, compromise claims and settle
Receivables and General Intangibles for less than face value and execute all
releases and other documents in connection therewith; 

          (h)  Pay any sums required on account of Borrower's taxes or to secure
the release of any liens therefor, or both; 

          (i)  Settle and adjust, and give releases of, any insurance claim that
relates to any of the Collateral and obtain payment therefor; 

          (j)  Instruct any third party having custody or control of any books 
or records belonging to, or relating to, Borrower to give Coast the same rights
of access and other rights with respect thereto as Coast has under this 
Agreement; and

          (k)  Take any action or pay any sum required of Borrower pursuant to
this Agreement and any other present or future agreements.  Any and all
reasonable sums paid and any and all reasonable costs, expenses, liabilities,
obligations and attorneys' fees incurred by Coast with respect to the foregoing
shall be added to and become part of the Obligations, and shall be payable on
demand.  Coast may charge the foregoing to Borrower's loan account and the
foregoing shall thereafter bear interest at the same rate applicable to the
Receivable Loans.  In no event shall Coast's rights under the foregoing power of
attorney or any of Coast's other rights under this Agreement be deemed to
indicate that Coast is in control of the business, management or properties of
Borrower.

          7.5  APPLICATION OF PROCEEDS.  All proceeds realized as the result of
any sale of the Collateral shall be applied by Coast first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by Coast
in the exercise of its rights under this Agreement, second to the interest due
upon any of the Obligations, and third to the principal of the Obligations, in
such order as Coast shall determine in its sole discretion.  Any surplus shall
be paid to Borrower or other persons legally entitled thereto; Borrower shall
remain liable to Coast for any deficiency.  If, Coast, in its sole discretion,
directly or indirectly enters into a deferred payment or other credit
transaction with any purchaser at any sale of Collateral, Coast shall have the
option, exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of purchase price or deferring the reduction
of the Obligations until the actual receipt by Coast of the cash therefor.

          7.6  REMEDIES CUMULATIVE.  In addition to the rights and remedies set
forth in this Agreement, Coast shall have all the other rights and remedies
accorded a secured party under the California Uniform Commercial Code and under
all other applicable laws, and under any other instrument or agreement now or in
the future entered into between Coast and Borrower, and all of such rights and
remedies are cumulative and none is exclusive.  Exercise or partial exercise by
Coast of one or more of its rights or remedies shall not be deemed an election,
nor bar Coast from subsequent exercise or partial exercise of any other rights
or remedies.  The failure or delay of Coast to exercise any rights or remedies
shall not operate as a waiver thereof, but all rights and remedies shall
continue in full force and effect until all of the Obligations have been fully
paid and performed.

generally accepted accounting principles, consistently applied.  All other 
terms contained in this Agreement, unless otherwise indicated, shall have the 
meanings provided by the Code, to the extent such terms are defined therein. 

          9.   GENERAL PROVISIONS.

          9.1  INTEREST COMPUTATION.  In computing interest on the Obligations,
all checks, wire transfers and other items of payment received by Coast
(including proceeds of Receivables and payment of the Obligations in full) shall
be deemed applied by Coast on account of the Obligations three (3) Business Days
after receipt by Coast of immediately available funds, and, for purposes of the
foregoing, any such funds received after 10:30 AM on any day shall be deemed
received on the next Business Day.  Coast shall not, however, be required to
credit Borrower's account for the amount of any item of payment which is
unsatisfactory to Coast in its sole discretion, and Coast may charge Borrower's
loan account for the amount of any item of payment which is returned to Coast
unpaid.  
          
          9.2  APPLICATION OF PAYMENTS.  All payments with respect to the
Obligations may be applied, and in Coast's sole discretion reversed and re-
applied, to the Obligations, in such order and manner as Coast shall determine
in its sole discretion.

          9.3  CHARGES TO ACCOUNTS.  Coast may, in its discretion, require that
Borrower pay monetary Obligations in cash to Coast, or charge them to Borrower's
Loan account, in which event they will bear interest at the same rate applicable
to the Loans.  Coast may also, in its discretion, charge any monetary
Obligations to Borrower's Deposit Accounts maintained with Coast.

          9.4  MONTHLY ACCOUNTINGS.  Coast shall provide Borrower monthly with
an account of advances, charges, expenses and payments made pursuant to this
Agreement.  Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Coast), unless Borrower
notifies Coast in writing to the contrary within thirty days after each account
is rendered, describing the nature of any alleged errors or omissions.

          9.5  NOTICES.  All notices to be given under this Agreement shall be
in writing and shall be given either personally or by reputable private delivery
service or by regular first-class mail, or certified mail return receipt
requested, addressed to Coast or Borrower at the addresses shown in the heading
to this Agreement, or at any other address designated in writing by one party to
the other party.  Notices to Coast shall be directed to the Commercial Finance
Division, to the attention of the Division Manager or the Division Credit
Manager.  All notices shall be deemed to have been given upon delivery in the
case of notices personally delivered, or at the expiration of one Business Day
following delivery to the private delivery service, or two Business Days
following the deposit thereof in the United States mail, with postage prepaid.  

          9.6  SEVERABILITY.  Should any provision of this Agreement be held by
any court of competent jurisdiction to be void or unenforceable, such defect
shall not affect the remainder of this Agreement, which shall continue in full
force and effect.

          9.7  INTEGRATION.  This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement between Borrower and Coast and supersede
all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement.  THERE ARE
NO ORAL UNDERSTANDINGS, REPRESENTATIONS OR AGREEMENTS BETWEEN THE PARTIES WHICH
ARE NOT SET FORTH IN THIS AGREEMENT OR IN OTHER WRITTEN AGREEMENTS SIGNED BY THE
PARTIES IN CONNECTION HEREWITH.

          9.8  WAIVERS.  The failure of Coast at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Coast shall not waive or
diminish any right of Coast later to demand and receive strict compliance
therewith.  Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar.  None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Coast shall be deemed to have been waived
by any act or knowledge of Coast or its agents or employees, but only by a
specific written waiver signed by an authorized officer of Coast and delivered
to Borrower.  Borrower waives demand, protest, notice of protest and notice of
default or dishonor, notice of payment and nonpayment, release, compromise,
settlement, extension or renewal of any commercial paper, instrument, account,
General Intangible, document or guaranty at any time held by Coast on which
Borrower is or may in any way be liable, and notice of any action

taken by Coast, unless expressly required by this Agreement.  

          9.9  NO LIABILITY FOR ORDINARY NEGLIGENCE.  Neither Coast, nor any of
its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Coast shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Borrower or any other party through the ordinary negligence of Coast, or any
of its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Coast, but nothing herein shall relieve Coast
from liability for its own gross negligence or willful misconduct.

          9.10  AMENDMENT.  The terms and provisions of this Agreement may not
be waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Coast.

          9.11  TIME OF ESSENCE.  Time is of the essence in the performance by
Borrower of each and every obligation under this Agreement.

          9.12  ATTORNEYS FEES, COSTS AND CHARGES.  Borrower shall reimburse
Coast for all reasonable attorneys' fees and all filing, recording, search,
title insurance, appraisal, audit, and other reasonable costs incurred by Coast,
pursuant to, or in connection with, or relating to this Agreement (whether or
not a lawsuit is filed), including, but not limited to, any reasonable
attorneys' fees and costs Coast incurs in order to do the following: prepare and
negotiate this Agreement and the documents relating to this Agreement; obtain
legal advice in connection with this Agreement or Borrower; enforce, or seek to
enforce, any of its rights; prosecute actions against, or defend actions by,
Account Debtors; commence, intervene in, or defend any action or proceeding;
initiate any complaint to be relieved of the automatic stay in bankruptcy; file
or prosecute any probate claim, bankruptcy claim, third-party claim, or other
claim; examine, audit, copy, and inspect any of the Collateral or any of
Borrower's books and records; protect, obtain possession of, lease, dispose of,
or otherwise enforce Coast's security interest in, the Collateral; and otherwise
represent Coast in any litigation relating to Borrower.  If either Coast or
Borrower files any lawsuit against the other predicated on a breach of this
Agreement, the prevailing party in such action shall be entitled to recover its
reasonable costs and attorneys' fees, including (but not limited to) reasonable
attorneys' fees and costs incurred in the enforcement of, execution upon or
defense of any order, decree, award or judgment.  Borrower shall also pay
Coast's standard charges for returned checks and for wire transfers, in effect
from time to time.  All attorneys' fees, costs and charges to which Coast may be
entitled pursuant to this Paragraph may be charged by Coast to Borrower's loan
account and shall thereafter bear interest at the same rate as the Receivable
Loans. 

          9.13  BENEFIT OF AGREEMENT.  The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Coast; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Coast, and any prohibited
assignment shall be void.  No consent by Coast to any assignment shall release
Borrower from its liability for the Obligations.

          9.14  PUBLICITY.  Coast is hereby authorized, at its expense, to issue
appropriate press releases and to cause a tombstone to be published announcing
the consummation of this transaction and the aggregate amount thereof.

          9.15  JOINT AND SEVERAL LIABILITY.  If Borrower consists of more than
one Person, their liability shall be joint and several, and the compromise of
any claim with, or the release of, any Borrower shall not constitute a
compromise with, or a release of, any other Borrower.

          9.16  LIMITATION OF ACTIONS.  Any claim or cause of action by Borrower
against Coast, its directors, officers, employees, agents, accountants or
attorneys, based upon, arising from, or relating to this Loan Agreement, or any
other present or future document or agreement, or any other transaction
contemplated hereby or thereby or relating hereto or thereto, or any other
matter, cause or thing whatsoever, occurred, done, omitted or suffered to be
done by Coast, its directors, officers, employees, agents, accountants or
attorneys, shall be barred unless asserted by Borrower by the commencement of an
action or proceeding in a court of competent jurisdiction by the filing of a
complaint within one year after the first act, occurrence or omission upon which
such claim or cause of action, or any part thereof, is based, and the service of
a summons and complaint on an officer of Coast, or on any other person
authorized to accept service on behalf of Coast, within thirty (30) days
thereafter.  Borrower agrees that such one-year period is a reasonable and
sufficient time for Borrower to investigate and act upon any such claim or cause
of action.  The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Coast in its sole discretion.  This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

used in this Agreement for convenience.  Borrower and Coast acknowledge that the
headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe, limit,

Agreement shall be construed strictly against Coast or Borrower under any rule
of construction or otherwise. 

          9.18  GOVERNING LAW; JURISDICTION; VENUE.  This Agreement and all acts
and transactions hereunder and all rights and obligations of Coast and Borrower

Agreement shall, at Coast's option, be litigated in courts located within

2.  INTEREST.

    INTEREST RATE ON LOANS
    (Section 1.2):         A rate equal to the "Prime Rate" plus 2.25% per 
                           annum. Interest is calculated on the basis of a 
                           360-day year for the actual number of days elapsed.
                           The interest rate applicable to all Loans shall be 
                           adjusted monthly as of the first day of each month, 
                           and the interest to be charged for each month shall 
                           be based on the highest "Prime Rate" in effect during
                           said month, but in no event shall the rate of 
                           interest charged for any loan in any month be less
                           than 9% per annum. "Prime Rate" means the actual
                           "Reference Rate" or the substitute therefor of the 
                           Bank of America NT & SA whether or not that rate is 
                           the lowest interest rate charged by said bank. If the
                           Prime Rate, as defined, is unavailable, "Prime Rate" 
                           shall mean the highest of the prime rates published 
                           in the Wall Street Journal on the first business day 
                           of the month, as the base rate on corporate loans at 
                           large U.S. money center commercial banks.

                             "Prime Rate" plus 2.00% per annum in the event 
                             Borrower reports one (1) quarter of profitability. 
                             The rate on the Loans shall be further reduced to 
                             the "Prime Rate" plus 1.75% per annum in the event 
                             Borrower reports two (2) consecutive quarters of
                             profitability. In the event Borrower reports a loss
                             in any quarter following any previous reduction in
                             the rate, the rate on the Loans shall revert back

                               CORPORATE OVERVIEW

Zycad Corporation (the Company), founded in 1981, develops, manufactures and
markets a broad range of high performance tools, design services and electronic
components that help designers speed the process of moving their electronic
products from concept to manufacturing.   Zycad calls this process, "Design
Realization."  It encompasses performing the steps necessary to complete design
verification and get to market in the quickest way possible.

Zycad's Design Realization offerings include hardware and software simulation
verification tools, rapid prototyping vehicles, high-density programmable
Application-Specific Integrated Circuits (ASICs) and related desktop design and
programming tools.  This suite of products enable electronic designers to
quickly and accurately verify their designs prior to production and support
initial and low volume ASIC production. Verification has the goal of minimizing
downstream problems and risks (i.e., avoiding the expensive and time-consuming
process of redesign should a final design not work or not meet the customer
requirements).  This process of Design Realization via comprehensive and fast
verification throughout the design cycle ensures a high quality, production-
ready product that meets the customers' time-to-market goals.

Zycad's twofold business emphasis is on providing both the highest performance
verification product offerings (including both simulation and rapid prototyping)
in the Electronic Design Automation (EDA) market, and the highest density
programmable ASICs to the ASIC designer for both design verification and design
realization through use as a reprogrammable component. All development
activities are focused on optimizing their future development and the
integration of these technologies to solve customer's high-end, complex
verification problems - the most dramatic being that of "system on a chip" or
"system on silicon" design verification.

Zycad's corporate office, and its product divisions are located in Fremont,
California.  Sales and support offices are located throughout the United States,
Europe, Japan and Asia.

                               TO OUR STOCKHOLDERS

1996 has been a year of transition for Zycad  in a very fragile market
environment. When we went to the Design Automation Conference in June, 90% of
our demonstrations represented new product introductions by our Verification and
GateField divisions.

While the year was disappointing from a financial perspective, significant
technical and business achievements were realized:

- -   The LightSpeed Simulation Server-TM- family was introduced at the Design
    Automation Conference in June with the first shipments in late Q3.
    LightSpeed offers customers unparalleled performance over existing solutions
    in the market place. Customer acceptance has been excellent with over 20
    systems in the field since late Q3.

- -   GateField presented its 51,000 gate ProASIC-TM- (programmable ASIC)
    technology in 0.8 micron structures and began development of a prototyping
    vehicle that combines GateField technology with partitioning software and
    multi-chip module technology.

    The GateField products created a great level of interest in the market
    place.  However, it was learned that the performance features of the
    products needed to be enhanced.  Consequently a very aggressive transfer
    into finer line geometries was initiated, resulting in "first time right"
    working silicon, offering complexity to 100,000 total gates. This product
    was delivered to customers during December 1996.

    Customer acceptance of GateField is also excellent, with 14 customer design
    wins in the fourth quarter of 1996. Major corporations in Japan and the U.S.
    were committing design resources to the new GateField product.

- -   The services and consulting business was merged with the GateField division
    during 1996.

- -   We completed the acquisition of Attest Software, Inc. in May 1996, further
    strengthening our test and fault product  offerings.

- -   A second DARPA contract, valued at $2.3 million for the development of a
    reconfigurable computing engine, based on GateField technology, was awarded
    in September 1996.

- -   The Company raised $10.0 million through subordinated convertible debentures
    note in May 1996.

In January 1996, Zycad and Quality Systems Software Ltd., an U.K. Company and
owner of the DOORS technology, established a joint venture, QSS, Inc., to
continue the distribution operations of the DOORS technology and other products
in the North American market. In December 1996, the entire company, including
the U.K. subsidiary, was consolidated under QSS, Inc.  Zycad's current
ownership at the end of 1996 is 22% (see Note 11 of Notes to Consolidated 
Financial Statements).

In summary, both divisions contributed in 1996, however, the financial
performance was a major disappointment to everyone, including our employees, who
have been tireless in their efforts to support us throughout this transition
period. On the positive side, the LightSpeed product was delivered to customers
in production volume in the fourth quarter.  The GateField 100K gate ProASIC was
introduced and shipped in the fourth quarter.  The engineering and consulting
services added positively to our performance throughout the year.

What are the challenges and opportunities for 1997 as we look forward?  The
LightSpeed Simulation Server family of products is expected to begin shipping
with the HDL interfaces for Verilog and VHDL in 1997. The VHDL interface should
be available in the first quarter of 1997. The Verilog interface should be
available in the second quarter of 1997. These interfaces are strategic to
addressing the broad logic simulation marketplace. The combination of LightSpeed
hardware and these strategic software interfaces should secure success
throughout 1997.

Our test and fault simulation product lines continue to be the industry standard
and contribute significantly to the Company's overall results. Several new
complimentary software and hardware products will be added to the hardware
accelerated fault simulation product line in 1997. In addition, significant
feature and function enhancements will be made to the software test products
associated with the Attest acquisition. These include improved support for HDL
interfaces and multiprocessing.  These additional capabilities should
significantly increase the market interest for these products in the second half
of 1997.

We believe that Zycad can and will be a leader in providing high density
reprogrammable ASICs to the $20 billion ASIC market.  No other suppliers are
delivering reprogrammable ASICs with logic gate densities equal to our 100K gate
part.  As we take advantage of advanced manufacturing processes, we should gain
even greater density advantages.  GateField is now shipping 0.6 micron parts and
by the third quarter of 1998 we expect to be shipping .35 micron parts which
will yield 400,000 reconfigurable logic-gates of capacity, much larger than any
current vendor can even contemplate in the 1998 timeframe.

GateField has proven that it can design and manufacture a part that is
competitive on speed, performance and functionality. We continue to focus on
design wins, as that is the primary driving force for growing market share.  A
design win positions Zycad competitively to vie for production volume business.
The customer typically moves towards product volume six to nine months after he
makes his initial design win selection.  GateField is achieving great success,
particularly in the Japanese market. A number of the big Japanese companies
became customers in the fourth quarter of 1996 and we expect continued growth in
1997.

It was a difficult year for all of us. We appreciate your patience, continued 
interest and loyalty during this transition year.  We remain committed to 
building a strong company. The tremendous investments, which were made in 
GateField are expected to yield significant results in the years ahead.

     Sincerely,



     Phillips W. Smith
     President and CEO

                                ZYCAD CORPORATION
                      MANAGEMENT'S DISCUSSION AND ANALYSIS

RESULTS OF OPERATIONS

OVERVIEW

The net loss for 1996 was $21.4 million, compared to net income in 1995 of $2.0
million. Total revenues for 1996 were $33.6 million, down $17.5 million from
1995. The reduction in revenue resulted in decreased gross margin:  $16.6
million for 1996 compared to $33.6 million in 1995. The loss in 1996 was
significantly impacted by one-time charges to cost of sales of $1.8 million (see
Gross Profit), as well as an additional $1.8 million of restructuring charges
and bad debt (see Operating Expenses). In addition the company expensed $2.5
million related to accelerated amortization of discount on the  $10.0 million
subordinated convertible debenture  notes (see Note 5 of Notes to Consolidated
Financial Statements).

Operating expenses increased by $3.9 million in 1996 to $35.0 million. This
increase reflects the Company's continued research and development investment in
the GateField division plus the introduction of the LightSpeed Simulation
Server.

The Company completed the acquisition of Attest Software, Inc. in May 1996 for
approximately $2.1 million further strengthening our test and fault product
offerings.

REVENUES
Total revenues decreased 34% to $33.6 million in 1996 from $51.1 million in 1995
and increased 2% in 1995 from $50.1 million in 1994.  Product revenues decrease
to $18.2 million in 1996 compared to $28.4 million in 1995, a decrease of  36%.
The decrease in product revenues in 1996 as compared to 1995 was primarily due
to decreased shipments of the Company's accelerator products and delays in
shipments of the next generation, faster LightSpeed accelerator product family,
introduced in late September 1996.  Product revenues decreased to $28.4 million
in 1995 compared to $29.4 million in 1994, a decrease of 3%.  This decrease was
primarily due to a decrease in Paradigm ViP and Paradigm RP-TM- product revenues
as the ViP product was discontinued at the end of 1994.  Additionally, emphasis
on the RP product was reduced, pending introduction of the GateField high-
density Programmable ASICs.  These decreases in revenues were partially offset
by purchases of the Paradigm XP-TM- products by the Company's largest customer.

Service revenues were $15.3 million, $22.7 million and $20.7 million in 1996,
1995 and 1994, respectively.  The decrease in service revenues from 1996 as
compared to 1995 was mainly due to the exclusion (i.e. non-consolidation)of 
revenue relating to the DOORS technology from revenue amounts in 1996, as 
well as reduced maintenance revenues related to older generation accelerator 
products and price reductions related to government contracts (see Note 2 of 
Notes to Consolidated Financial Statements).  The increase in service 
revenues in 1995 as compared to 1994 was primarily due to increased demand 
for the DOORS technology and increases in commercial contracts.

GROSS PROFIT
Gross profit from total revenues was $16.6 million, $33.6 million and $30.1
million in 1996, 1995 and 1994, respectively.  Gross profit as a percentage of
total revenues was 49%, 66% and 60% for the same years ended December 31, 1996,
1995 and 1994, respectively.

Gross profit from product revenues was $9.8 million, or 54% of product sales in
1996 compared to $22.0 million, or 77% of product sales in 1995.  This decrease,
both in dollars and as a percentage of product revenues was primarily due to
decreased product revenues as well as certain one-time charges of approximately
$1.8 million related to the write down of inventories in 1996. Other factors
contributing to the decrease in gross profit from product revenues in 1996 were
product mix of the LightSpeed product line, which included lower margins during
introduction, and higher discounts offered to customers for older generation
products.  Gross profit from product revenues increased $0.9 million in 1995,
despite lower revenues as compared to gross profit from product revenues in
1994, primarily due to a shift in product mix to shipments of the higher-margin
Paradigm XP products.

Gross profit from service revenues was $6.8 million, $11.6 million and $9.0
million in 1996, 1995 and 1994, respectively.  Gross profit as a percentage of
service revenues was 44%, 51% and 43% for the years ended December 31, 1996,
1995 and 1994, respectively.  The decrease in gross profit from service revenues
in 1996 compared to 1995 was primarily due to decreased maintenance revenues in
1996 as well as the exclusion of DOORS revenues, which generally had a higher
profit margin.  Gross profit from service revenues increased $2.6 million in
1995 compared to 1994, while service revenues increased $2.0 million.  This
increase in gross margin was mainly due to a shift to sales of higher-value
commercial service contracts from lower-margin service contracts affiliated with
the mil/aero products in 1994.


OPERATING EXPENSES

SALES AND MARKETING
Sales and marketing expenses were $14.3 million, or 43% of total revenues, $16.9
million, or 33% of total revenues and $18.9 million, or 38% of total revenues in
1996, 1995 and 1994, respectively.  The decrease in actual expenses for 1996
compared to 1995 was primarily due to the inclusion of DOORS expenses of $2.1
million in 1995 (see Note 2 of Notes to Consolidated Financial Statements).  The
increase in sales and marketing expenses as a percentage of total


                                        4
<PAGE>


revenues for 1996 as compared to 1995 was attributable to reduced revenues as
well as higher marketing expenses in 1996 related to the introduction of the
LightSpeed product.  In 1995, sales and marketing expenses decreased 11%, or
$2.0 million, compared to 1994, primarily due to reduced staffing levels
resulting from the restructuring actions taken in December 1994.

RESEARCH  AND DEVELOPMENT
The Company's research and development expense was $15.8 million, $11.3 million
and $11.2 million in 1996, 1995 and 1994, respectively.  The increase in
research and development expense in 1996 compared to 1995 was mainly due to
additional staffing levels and higher levels of engineering project activity
associated with the introduction of both the LightSpeed and the high-density
programmable ASICs product lines.

Research and development expense was relatively constant in 1995 and 1994.  Due
to the restructuring in December 1994, personnel expense was lower in the first
half of 1995, but increased in the second half of 1995 as the Company began its
development for the next generation accelerator, LightSpeed and GateField
Programmable ASICs programs.

GENERAL AND ADMINISTRATIVE
General and administrative expenses were $4.9 million, $2.9 million and $2.7
million in 1996, 1995 and 1994, respectively.  The increase in general and
administrative expenses for  1996 was primarily due to $1.0 million of bad debt
expense for potential uncollectable accounts receivable.  An additional $0.8
million of expense in the second half of 1996 was attributable to the Company's
decision to restructure the organization in order to seek profitability and
growth.  These expenses included severance and other fringe benefits related to
a reduction in force.

General and administrative expenses increased $0.2 million, or 6%,  in 1995 over
1994.  This increase remained relatively constant as a percentage of revenues
and was primarily due to increases necessary to support revenue growth as well
as higher special project costs.

ASSET WRITE-DOWNS AND STAFF REDUCTIONS
In the fourth quarter of 1994, the Company decided to discontinue selling its
VHDL accelerator product, the Paradigm ViP.  This decision resulted from
disappointing financial performance in 1994 and the re-direction of the product
diversification strategy.  Non-recurring costs of $6.8 million, principally
related to write-downs of capitalized software and inventory for the ViP product
line and staff  reduction costs, were charged against income (see Note 4 of
Notes to Consolidated Financial Statements).

OTHER INCOME AND EXPENSE
Interest expense was $3.2 million in 1996 compared to $0.3 million in 1995 and
$0.2 million in 1994.  This increase in 1996 was primarily due to $2.5 million
of the acceleration of amortization of discount expense related to the portion
of the Company's subordinated convertible debenture notes (see Note 5 of Notes
to Consolidated Financial Statements).  Additionally, the Company recorded
higher interest expense related to higher borrowings and higher interest rates.

Other income was $0.2 million in 1996 and other expense was $0.3 million and
$0.1 million in 1995 and 1994, respectively.  This fluctuation from year to year
was primarily due to transaction gains and losses related to foreign currency
adjustments.

INCOME TAXES
The Company did not record income tax expense (benefit) in 1996, 1995 and 1994
due to losses or the availability of net operating loss carryforwards (see Note
8 of Notes to Consolidated Financial Statements).

NET INCOME (LOSS)
The net loss for 1996 was $21.4 million, compared to net income in 1995 of $2.0
million and a net loss in 1994 of $9.7 million.  In addition to reduced revenues
and decreased gross margin percentage  for 1996, the loss in 1996 was
significantly impacted by one-time charges to cost of sales of $1.8 million,
discussed above in "Gross Profit", an additional $1.8 million of bad debt and
restructuring charges as discussed in "General and Administrative" and $2.5
million of amortization expense related to debenture discounts as discussed in
"Other Income and Expense".

The Company's net income of $2.0 million in 1995 represents an $11.7 million
improvement over the 1994 financial results based on increased revenues of $1.1
million.  The Company's net income was comprised of $5.4 million profit
attributable to revenues from its accelerator  business activity, $1.6 million
profit related to marketing and distribution of requirements management
technology, DOORS, owned by a third-party U.K. company, offset by $5.0 million
of expenses related to the development of the GateField Programmable ASICs.

The loss in 1994 included $6.8 million of asset write-downs and restructuring
costs as the Company continued to sell its ViP product and concentrated on fewer
product technology areas, as discussed in "Asset Write-Downs and Staff
Reductions".

FACTORS AFFECTING FUTURE RESULTS
The Company's revenues during 1994 through 1996 consisted principally of its 
fault and simulation products, such as the Paradigm PXP and TDX products. 
Revenue for these products declined during the three year period. The 
Company's plans to offset this trend is principally dependent on the 
successful introduction of the GateField high-density reprogrammable ASICs.

The Company continues to seek improvement in operating results through
introduction of new products, including verification tools and Field
Programmable Gate Array (FPGA) products. However, there can be no assurance that
the Company will be successful in its efforts. In the future, the Company's
operating results may be impacted by a number of factors, including
cancellations 

                                        5

or delays of customer orders, interruptions or delays in the supply of key 
components, changes in customer base or product mix, seasonal patterns of 
capital spending by customers, new product announcements by the Company or 
its competitors, pricing pressures and changes in general economic 
conditions. Historically, a significant portion of the Company's shipments 
have been made in the last month of each quarter. As a result, a shortfall in 
revenue compared to expectation may not evidence itself until late in the 
quarter. Additionally, the timing of expenditures for research and 
development activities and sales and marketing programs, as well as the 
timing of orders by major customers, may cause operating results to fluctuate 
between quarters and between years.

LIQUIDITY AND CAPITAL RESOURCES
The Company has historically used internally generated funds, public and private
offerings of common stock, sale and leaseback arrangements and bank financing
and credit lines to finance its business.  Cash used in operations was $12.6
million in 1996 compared to cash generated by operations of $5.4 million in
1995. The increase in cash used in operations in 1996 was primarily due to the
net loss generated by operations, net sales under capital leases and a growth in
inventories, partially offset by a growth in accounts payable and accrued
liabilities.  Cash generated by operations of $5.4 million in 1995 was the
result of net income of $2.0 million, an increase in accounts payable and a
decrease in accounts receivable and other assets, offset by an increase in
inventories and a decrease in accrued expenses.  Cash used in investing
activities was $3.5 million in 1996, compared to $2.0 million in 1995, relating
primarily to capital equipment purchases and increased levels of capitalized
software.  Net cash generated by financing activities was $13.9 million in 1996,
compared to net cash used in financing activities of $2.6 million in 1995.  Cash
generated by financing activities in 1996 was primarily attributable to a $10.0
million subordinated convertible debenture notes offering in the second quarter,
$3.2 million in bank borrowings through use of factoring agreements, as well as
$0.7 million provided by the issuance of the Company's Common Stock.

At December 31, 1996 the Company had cash and cash equivalents of $1.7 million
and a working capital deficit of $(1.2) million at December 31, 1996 compared to
working capital of $6.7 million at December 31, 1995.  The Company has a $3.1
million factoring arrangement with a bank which expires in October 1997, of
which $1.8 million was outstanding at December 31, 1996 (see Note 5 of Notes to
Consolidated Financial Statements). The Company's Japan subsidiary also has bank
factoring agreements for $1.4 million (see Note 5 of Notes to Consolidated
Financial Statements).  Additionally, the Company, subsequent to December 31,
1996, obtained a $5.0 million line of credit with a lender that allows for the
use of substantially all of the Company's tangible assets as collateral (see
Note 11 of Notes to Consolidated Financial Statements).

The Company continues to work with certain vendors to facilitate extended trade
terms, thus reducing the Company's immediate cash requirements to meet
established payments and other normal, recurring period expenses.  It is
anticipated that minimum working capital will be required to meet sales demands
because levels of PXP and LightSpeed inventories should meet demands through the
second quarter of 1997.

The Company's operating and product development activities have required
significant cash. In anticipation of meeting the Company's 1997 cash
requirements, in February 1997, the Company completed a $5.0 million private
placement financing agreement with investors whereby the Company issued 6%
subordinated convertible debenture notes which can be converted into shares of
the Company's Common Stock.  This funding is available to the Company in
traunches of $3.5 million upon closure of the debenture agreement and $1.5
million upon registration of additional shares of the Company's Common Stock
through the effective filing of an S-3 Registration Statement under the
Securities Act of 1933.  The discount expense relating to these subordinated
convertible debenture notes is $0.9 million for the $3.5 million of funding and
$0.4 million for the $1.5 million of funding.  This discount will be amortized
within 180 days of receipt of the cash (see Note 11 of Notes to Consolidated
Financial Statements).

The Company's debenture agreements specify certain events of default upon 
which the debentures would become immediately payable, including a delisting 
of the Company's Common Stock from the Nasdaq Stock Market. At December 31, 
1996, the Company was not in compliance with the requirement of the Nasdaq 
National Market (a distinct tier of the Nasdaq Stock Market) to maintain 
minimum net tangible assets (as defined) of $4,000,000. A hearing is 
scheduled for April 23, 1997 for Nasdaq to consider the Company's plans to 
come into compliance with such requirement. The Company believes that if its 
stock were delisted from the Nasdaq National Market, it would be eligible for 
listing in the Nasdaq SmallCap Market, which is another tier of the Nasdaq 
Stock Market, and, accordingly, believes it would remain in compliance with 
the debenture requirement to trade on the Nasdaq Stock Market; however, no 
assurances can be given.

The Company anticipates that by attaining revenue projections for 1997 and by 
relying on the new credit line, together with sources of additional liquidity 
such as private or public offerings, equipment lease lines and the sale of 
certain Company assets (see Note 11 of Notes to Consolidated Financial 
Statements) the Company expects to meet short-term liquidity needs.  Should 
additional funding be required, however, there can be no assurance that such 
funding will be available on acceptable terms as and when required by the 
Company.

                                ZYCAD CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994

NOTE 1: ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND OPERATIONS
Zycad Corporation (the Company), based in Fremont, California, designs,
manufactures, markets and services high-performance, simulation acceleration
technology  and related software that address the issues associated with the
design verification of complex integrated circuits (ICs), application specific
integrated circuits (ASICs) and electronic systems as well as high density
reprogrammable ASIC technology (ProASIC).  The Company also provides system
engineering services and custom solutions to military, aerospace and commercial
companies, primarily in the U.S., Asia and Europe.

The Company  incurred a loss of $21,376,000 in 1996 and had a working capital
deficit of $1,240,000 as of year end.  Management's plan to sustain operations
in 1997 includes obtaining additional financing and the sale of certain Company
assets.  This plan was implemented in early 1997 and has resulted in the
completion of two financing agreements and one asset sale agreement (see Note 
2 and Note 11).

PRINCIPLES OF CONSOLIDATION AND PRESENTATION
The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated in consolidation. The functional currency of
the Company's foreign subsidiaries is the local currency.

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

CASH EQUIVALENTS
Cash and cash equivalents consist of cash on deposit with banks and money market
instruments with original maturities of three months or less.

SHORT-TERM INVESTMENTS
Short-Term investments consist of Certificates of Deposit, stated at cost plus
accrued interest, which approximates  market.

CONCENTRATION OF CREDIT RISK
Financial instruments which potentially subject the Company to concentrations of
credit risk consist primarily of cash and cash equivalents, short-term
investments and trade accounts receivable.  The Company invests only in high
credit quality short-term debt investments and limits the amount of credit
exposure to any one entity.  The majority of the Company's trade accounts
receivable are derived from sales to manufacturers in the semiconductor,
computer, military and aerospace industries. The Company performs ongoing credit
evaluations of its customers financial condition and limits the amount of credit
extended when deemed necessary, but generally requires no collateral.  The
Company maintains reserves for potential credit losses.

INVENTORIES
Inventories are stated at the lower of standard cost, which approximates actual
cost on a first-in, first-out basis, or market.

PROPERTY AND EQUIPMENT
Property and equipment is stated at cost.  Equipment acquired under capital
lease obligations is stated at the lower of fair value or the present value of
future minimum lease payments at the inception of the lease.  Depreciation and
amortization is provided over the estimated useful lives of the assets or over
the life of the lease, as applicable, using the straight-line method.  Field
spares are amortized over the estimated life of the related product.

On January 1, 1996, the Company adopted Statement of Financial Accounting
Standards No. 121 (SFAS No. 121), "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed of".  The adoption of this
standard had no effect on the Company's financial condition or results of
operations.

CAPITALIZED SOFTWARE
The Company capitalizes software development costs in accordance with Statement
of Financial Accounting Standards No. 86 (SFAS No. 86), "Accounting for the
Costs of Computer Software to be Sold, Leased or otherwise Marketed".
Amortization of capitalized software development costs begins upon initial
product shipment. Software development costs are amortized (a) over the
estimated life of the related product, generally thirty-six months, using the
straight-line method, or (b) based on the ratio of current revenues from the
related products to total estimated revenues for such products, whichever is
greater.

STOCK-BASED COMPENSATION
The Company accounts for stock-based awards to employees using the intrinsic
value method in accordance with Accounting Principles Board No. 25 (APB No. 25),
"Accounting for Stock Issued to Employees".  The Company has presented the pro
forma disclosures of compensation expense under the fair value provisions of the
recently issued Statement of Financial Accounting Standards No. 123 (SFAS No.
123), "Accounting for Stock-Based Compensation" in Note 10.


                                       12
<PAGE>

REVENUE RECOGNITION
The Company generally recognizes product revenues at the time of shipment, but
may delay revenue recognition until products are installed or accepted,
depending on the particular product and contract terms. Design and verification
service revenues are recognized as the services are performed.  Revenues from
the sale of maintenance contracts are recognized  over the term of the
respective contract.

INCOME TAXES
The Company follows Statement of Financial Accounting Standards No. 109 (SFAS
No. 109), "Accounting for Income Taxes," which requires an asset and liability
approach to account for income taxes and requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of temporary
differences between the financial statement carrying amounts and the tax basis
of assets and liabilities and net operating loss and tax credit carryforwards.

NET INCOME (LOSS) PER SHARE
Net income (loss) per share is computed using the weighted average number of
common shares outstanding during each period including dilutive common share
equivalents, which consist of common stock options and warrants.  Net loss per
share is computed using the weighted average number of common shares
outstanding. Common share equivalents are not included in the net loss per share
calculation because the effect would be anti-dilutive.

RECLASSIFICATION
Certain previously reported amounts in the 1995 and 1994 consolidated financial
statements and notes have been reclassified to conform with the 1996
presentation.


NOTE 2:  CERTAIN TRANSACTIONS

JOINT VENTURE
The Company's financial statements include the activities related to the
distribution of third-party owned technology, DOORS, for the years ended
December 31,  as follows (in thousands):

                                 1995        1994
                              --------   --------
Service revenues              $  5,400   $  2,100
Cost of service revenues         1,700        600
                              --------   --------
Gross profit                     3,700      1,500
Sales and marketing expenses     2,100        600
                              --------   --------
Operating income              $  1,600   $    900
                              --------   --------
                              --------   --------

The net assets related to the DOORS activities are not material.  In January
1996, the Company and Quality Systems Software, Ltd. (QSS Ltd.), a U.K. company
and owner of the DOORS technology, established a joint venture, QSS Inc., to
continue the distribution operations of the DOORS technology and other products
in the North American market.

During 1996, the Company reported its 40% ownership of QSS Inc. on a 
non-consolidated, one-line equity basis rather than in the detail as shown 
above, for 1995 and 1994.  For the year ended December 31, 1996, the 40% 
equity share of the joint venture profit was $160,000 (included in Other 
Income).  In January 1997, QSS Inc. was restructured so that QSS Ltd. became 
a subsidiary of QSS Inc.  The Company's ownership as a result of the QSS Inc. 
restructuring became 22% (see Note 11 concerning the subsequent sale of the 
Company's interest).

COMPANY STOCK TRANSACTION
On March 14, 1994 the Company raised $3,100,000 of cash, net of broker fees and
discounts through the sale of 1,500,000 shares of its Common Stock including all
of its treasury shares.  These shares were sold to foreign investors under the
provisions of Regulation S of the Securities Act of 1933, as amended (the
Securities Act).

NOTE 3:  PURCHASED TECHNOLOGY

In June 1996, the Company acquired Attest Software, Inc. (Attest), located in
Santa Clara, California, in exchange for approximately 387,000 shares of the
Company's Common Stock, valued at approximately $2,140,000, for all the
outstanding Common Stock of Attest.  This transaction was accounted for as a
purchase; accordingly, the operations of Attest have been included in the
consolidated results of the Company since the day of acquisition.  The operating
results of Attest prior to the acquisition were not significant. As part of this
transaction, the technology purchased, used for fault simulation and automatic
test pattern generation (ATPG) tools, was valued at $2,055,000 which is being
amortized over seven years. Accumulated amortization was $165,000 at December
31, 1996.

In September 1993, the Company acquired Integrated Circuit Applications, Ltd.
(InCA), located in Ascot, United Kingdom for $450,000 cash and 460,000 shares of
the Company's Common Stock valued at approximately $1,322,000. This transaction
was accounted for as a purchase; accordingly, the operations of InCA have been
included in the Consolidated Results of the Company since the date of
acquisition.  The operating results of InCA prior to the acquisition were not
significant..  As part of this transaction the technology purchased was valued
at $1,692,000 which is being amortized over seven years. Accumulated
amortization was $806,000,  $564,000 and $322,000 at December 31, 1996, 1995 and
1994, respectively.  The technology is utilized in the rapid prototyping and
emulation product markets  and has been incorporated into the GateField
Programmable ASICs technology.

NOTE 4: ASSET WRITE-DOWNS AND STAFF REDUCTIONS

During fourth quarter 1994, the Company recorded $6,800,000 of expenses, of
which $5,300,000 related to discontinuing its Paradigm ViP product line.  The
remaining $1,500,000 was primarily related to various asset write-downs and
staff reductions.  Details of the write-off are as follows (in thousands):

NON-CASH ASSET WRITE-DOWNS
 ViP inventory                                $    750
 ViP related capital equipment,
  including demos and spares                       500

                                              --------
  Total                                       $  6,800
                                              --------
                                              --------

NOTE 5:  BANK FINANCING AND LONG-TERM DEBT

BANK BORROWINGS
The Company has a $3,125,000 factoring agreement  which bears an interest rate
of 1.5% per month and certain administrative fees, that expires in October 1997.
Under the factoring agreement, the Company can sell up to 80% of any receivable
listed on an invoice and the buyer may exercise its sole discretion in approving
the credit of each Account Debtor before buying any receivable.  At December 31,
1996, the balance outstanding under this factoring agreement was $1,840,000.
Additionally, the Company's Japan subsidiary has promissory notes  discounted
with banks in the amount of $1,363,000 that have been classified as bank
borrowings in accordance with Statement of Financial Accounting Standards  No.
77 (SFAS No. 77), "Reporting by Transferors for Transfers of Receivables with
Recourse."

TERM LOANS
In 1995 and 1996, the Company entered into long-term loan agreements totalling
$2,179,000 that bear interest rates of 10.66% to 15.33% and mature over 36
months.  These loans are secured by specific capital assets.  At December 31,
1996, the balance outstanding under these loans was $810,000,  with $644,000 due
in 1997 and  $246,000 in 1998.  In 1996, the Company obtained promissory notes
totalling $901,000 from key vendors that bear interest rates from 12% to 18%.
These notes are payable in the first nine months of 1997.

SUBORDINATED CONVERTIBLE DEBENTURE NOTES
In May 1996, the Company sold a total of $10,000,000 of subordinated convertible
debenture notes (the Notes) to institutional investors as part of a private
placement.  The Notes accrue interest at an annual rate of 6%, beginning on the
date of issue, with the principal due and payable three years from the date of
issue if and to the extent that the Notes are not previously converted.  The
Notes are convertible at the option of the noteholders (subject to the maximum
share limitations set forth below) into Common Stock at a price equal to 80% to
85% of the average closing bid price for the Common Stock on the Nasdaq National
Market for the five trading days prior to the date of conversion.  In addition,
the investors received warrants to purchase up to 100,000 additional shares of
the Company's stock at $10.00 per share, subject to certain conditions.

The conversion of the Notes at 80% to 85% of the average closing bid price of
the Company's Common Stock results in the Notes being issued at a 15% to 20%
discount (the Conversion Discount).  The Conversion Discount is being recognized
by the Company as non-cash interest expense from the date of issuance through
the date the security is most favorably convertible to the noteholders, with a
corresponding increase to the original principal amount of the Notes.  Upon
conversion of the Notes, any portion of the Conversion Discount not previously
recognized is recorded as interest expense on that date.  In addition, the
stated 6% annual interest is being recognized ratably over the term of the
Notes.  During the year ended December 31, 1996, a total of $2,836,000 was
recorded as interest expense relating to the Notes, including $2,500,000
relating to the Conversion Discount.

The $10,000,000 original principal amount of the Notes is convertible up to 
the maximum number of shares of the Company's Common Stock legally available 
therefor, with each individual Note limited to a pro-rata amount of such 
number of shares.  To the extent that the debentures are still outstanding 
after 180 days, the Company is obligated to issue a 2 1/2 year warrant to 
purchase 10,000 shares of Zycad Common Stock at an exercise price of $10 per 
share for each $1,000,000 of debentures outstanding to a maximum of 100,000 
shares (pro-rated for each part $1,000,000).  The warrants are redeemable by 
the Company for $0.01 for each 10,000 share warrant if the Zycad stock price 
is above $12.  The Company issued 59,500 warrants in 1996.  No value was 
assigned to the warrants as the value was deemed to be nominal.  During 1996, 
an aggregate of $5,431,000 ($4,300,000 of the original principal of the Notes 
and $1,131,000 of accrued interest) had been converted into 2,691,000 shares 
of Common Stock.  At December 31, 1996, the $7,342,000 outstanding balance of 
the Notes consisted of $5,700,000 of the original principal amount of the 
Notes and $1,642,000 of accrued interest. At December 31, 1996 approximately 
3,179,000 shares of Common Stock had been reserved for conversion of the 
remaining debentures.

In the event that the shares of Common Stock underlying a particular Note cannot
be issued upon request for conversion due to the above referenced maximum share
limitations, the Company is immediately obligated to repay the original
principal of that portion of the Note which is presented for 


                                       14
<PAGE>


conversion which cannot be converted plus a premium equal to 2%, starting 
on the 31st day and each 30-day period thereafter, of such principal plus any 
accrued and unpaid interest.

The debenture agreement specifies certain events of default, upon which the
debentures would become immediately payable, including a delisting of the
Company's Common Stock from the Nasdaq Stock Market.  At December 31, 1996, the
Company was not in compliance with the requirement of the Nasdaq National Market
(a distinct tier of the Nasdaq Stock Market) to maintain minimum net tangible
assets (as defined) of $4,000,000.  A hearing is scheduled for April 23, 1997
for Nasdaq to consider the Company's plans to come into compliance with such
requirement.  The Company believes that if its stock were delisted from the
Nasdaq National Market, it would be eligible for listing in the Nasdaq SmallCap
Market, which is another tier of the Nasdaq Stock Market, and, accordingly,
believes it would remain in compliance with the debenture requirement to trade
on the Nasdaq Stock Market.

Based on the conversion of $3,970,000 of subordinated convertible debenture 
notes and accrued interest to common stock in the first quarter of 1997 and 
$256,000 in the second quarter, through April 14, 1997, and the agreement to 
sell its interest in QSS, all as discussed in Note 11, and its projected 
results for 1997, the Company believes it will remain listed on Nasdaq in 
1997 and, accordingly, not cause an event of default with its debenture 
agreement; however, no assurance can be given.

NOTE 6:  LEASES AND COMMITMENTS

The Company leases its facilities and other equipment under operating lease
agreements which expire at various dates through 2002.  The Company also leases
certain manufacturing equipment under capital leases which expire in 1999.
Approximate future minimum lease payments under these leases are as follows (in
thousands):

Total  operating   lease   expense   was    approximately $1,954,000 in 1996,
$1,638,000 in 1995 and $2,143,000 in 1994.  Accumulated depreciation of
equipment under capital leases totalled $561,000 and $297,000 at December 31,
1996 and 1995, respectively.  Depreciation expense on equipment under capital
leases was $264,000 in 1996, $204,000 in 1995 and $93,000 in 1994.

The Company leases office facilities under operating leases. Rent expense of 
$1,732,000, $1,602,000 and $2,248,000 was incurred in 1996, 1995, and 1994, 
respectively. During 1994, the Company sold $612,000 of its lease receivables 
to certain finance companies.  At December 31, 1996, the Company remains 
contingently liable in the event of uncollectability for $128,000 to these 
finance companies. During 1993, the Company entered into a joint development 
agreement with a European company under which the Company agreed to spend 
approximately $2.5 million over three years.  At December 31, 1996, 
approximately $185,000 remained under this obligation.

The Company was not required to pay income taxes in 1996, 1995 or 1994 due to
its net operating loss carryforwards.

Significant components of the Company's deferred tax asset are as follows:

                                                             December 31,

The valuation allowance was established due to uncertainty regarding the
utilization of the net operating loss carryforwards.  The net change in
valuation allowance was an increase of $8,804,000, a decrease of $991,000 and an
increase of $4,365,000 in 1996, 1995 and 1994, respectively.

Net pretax foreign income (losses) were ($620,000),  $185,000 and $(261,000) in
1996, 1995 and 1994, respectively.  The Company intends to indefinitely reinvest
the unremitted earnings of its foreign subsidiaries.  The Company has net
operating loss carryforwards of approximately $46,300,000  for federal tax
purposes that will begin to expire in 2005.  State operating loss carryforwards
expires as follows: $5,000,000 in 1997, $335,000 in 1998, $30,000 in 1999,
$90,000 in 2000 and $10,710,000 in the year 2001.  The Company's tax credit
carryforwards of  $2,800,000 and $378,000 available to reduce future federal and
California income taxes, respectively. These credits will expire beginning in
1999. The Company also has foreign net operating loss carryforwards of
approximately $3,500,000 which may be used to offset future foreign taxable
income.

The Tax Reform Act of 1986 and California Conformity Act of 1987 impose
substantial restrictions on the utilization of net operating losses and tax
credit carryforwards in the event of an "ownership change" as defined by the
Internal Revenue Code.  If there should be such a change, the Company's ability
to utilize the stated carryforwards could be significantly limited.

The amounts reported for Europe and Japan reflect amounts sold by foreign
subsidiaries.  Included in the domestic revenue amounts are sales directly to
Japan and other Asian countries amounting to $2,116,000 in 1996, $6,100,000 in
1995 and $2,200,000  in 1994.  Outside the United States, the Company operates
three subsidiaries  in Europe, one subsidiary  in Japan and also supports a
branch office in Taiwan.  For the years ended December 31, 1996, 1995 and 1994,
export sales (including sales by foreign subsidiaries), principally to Europe
and Japan,  comprised approximately  31%, 30% and  26% of consolidated revenues,
respectively.  During 1996, 1995 and 1994, one customer accounted  for 10%, 17%
and 14% of consolidated revenues, respectively.

NOTE 10: STOCKHOLDERS' EQUITY

PREFERRED STOCK
The Company's Articles of Incorporation were duly amended by a proposal by the
Board of Directors November 1, 1996 and by vote of the stockholders at a special
meeting on December 5, 1996, to authorize the issuance of 2,000,000 shares of
undesignated Preferred Stock at $0.10 par value.  There were no outstanding
shares of Preferred Stock at December 31, 1996.

COMMON STOCK
The Company's Articles of Incorporation were duly amended by a proposal by the
Board of Directors November 1, 1996 and by vote of the stockholders at a special
meeting on December 5, 1996, to increase the Company's Common Stock by
10,000,000 shares from 30,000,000 to 40,000,000 shares of Common Stock
authorized at $0.10 par value.  At December 31, 1996 there were 23,226,444
shares of the Company's Common Stock outstanding.

STOCK COMPENSATION PLANS
Under the Company's stock option plans, options to purchase shares of Common
Stock may be granted to employees and directors at not less than the fair market
value on the effective date of the grant, as determined by the Board of
Directors.  Dependent on the plan, options typically vest at specified intervals
over a three to four year period, and expire eight to ten years after the grant
date.  In the event of termination, the Company has the right to cancel any
vested options not exercised within 90 days of the termination.  Cancelled
options are returned to the options plans and are available for future grants.

Options granted to officers subsequent to June 22, 1990 provide for acceleration
of exercisability in the event of an acquisition of the Company that meets
certain defined criteria. The plans also permit the granting of incentive and
nonstatutory stock options and stock appreciation rights (SARs). At December 31,
1996, there were no SARs outstanding.  In October 1996, the Company's Board of
Directors adopted the 1996 Stock Option Plan which was ratified by shareholders
in December, 1996.  Under this plan, 750,000 shares of the Company's Common
Stock were reserved for issuance under this plan.  In August 1993, the Company's
Board of Directors adopted the 1993 Stock Option Plan which was ratified by
shareholders in December 1995.  Under this plan, 1,500,000 shares of the
Company's Common Stock were reserved for issuance in 1993, and subsequently
increased to 3,000,000 in 1995. In September, 1993, the CEO of the Company
exercised 900,000 options granted under the 1984 Stock Option Plan for a
$900,000 secured promissory note which was paid in 1995.

During 1995 stockholders approved a Non-Employee Directors' stock option plan,
whereby 200,000 additional shares have been reserved for issuance to outside
directors. No options have been issued under this plan.

In October 1996, the Company agreed to exchange outstanding options to purchase
the Company's Common Stock held by all employees for an equal number of options
with an exercise price of $1.63, the then-current fair market value of the
Company's Common Stock.  In return, participating employees who chose to
exchange their options agreed to accept stock options which will vest on a
quarterly basis upon achievement of certain management goals to be established
quarterly for each such employee, or in any event, in October 2000, should the
employee still be employed by the Company.  Options covering a total of
1,040,100 shares were exchanged under this program.  The effect of such exchange
reduced the weighted average exercise price of the outstanding options from
$3.24 to $1.90 per share.  The effect of the exchange has been included in the
accompanying table as options granted and cancelled.

In October 1995, the Financial Accounting Standards  Board issued SFAS No. 123,
which establishes financial accounting and reporting standards for stock-based
employee compensation plans.  This statement defines a fair value based method
of accounting for an employee stock option of similar equity instrument.  Under
these method, compensation costs are measured at the grant date based on the
value of the award and are recognized over the service period, which is the
vesting period.

The Company continues to account for its stock-based awards using the intrinsic
value method in accordance with APB No. 25 and its related interpretations.
Accordingly, no compensation expense has been recognized in the financial
statements for employee stock option plans (see Note 1).  Had compensation cost
for the Company's various stock option plans been determined consistent with
SFAS No. 123, the Company's net income or loss and net income or loss per share
would have been changed to the pro forma amounts indicated below (in thousands,
except net income or loss per share amounts):

assumptions used for grants in 1996 and 1995, respectively; expected volatility
of 90% for 1996 and 84% for 1995, risk-free interest rates of 6.07% and 6.16%
for 1996 and 1995, respectively, and expected lives of 3.5 years from the grant
date  for both 1996 and 1995.

EMPLOYEE STOCK PURCHASE PLAN
Through the Company's Employee Stock Purchase Plan, eligible employees of the
Company may purchase Common Stock at the fair market value of the stock at the
beginning or end of each offering period (calendar quarters), whichever is
lower. Each participant may contribute from 3% to 10% of total compensation, up
to a limit of $25,000 annually.  Additionally, each participant is prohibited
from owning more than 5% of the Company's Common Stock.  In December 1995,
200,000 shares of Common Stock were made available for purchase under this plan,
of which 25,913 shares were issued at December 31, 1996, for prices ranging from
$1.72 per share to $5.25 per share and an average price of $2.98 per share.  At
December 31, 1996, 174,087 shares were reserved for future issuance under the
Purchase Plan.  The fair value of the 1996 awards was not considered
significant.

EMPLOYEE 401(k) PLAN
Through the Company's elective 401(k) savings plan, eligible U.S. employees of
the Company may contribute up to 20% of their pre-tax earnings, subject to
current IRS restrictions.  Under the plan, the Company may make discretionary
matching contributions up to 25% up to the first 10% of an employee's
contributions.  The participants vest in the Company's contribution over five
years.  Company contributions to this plan were $200,000 in 1996, $198,000 in
1995 and $256,000 in 1994.

WARRANTS
At December 31, 1996, total warrants outstanding were 194,500.  Purchase price
of the securities subject to these warrants range from $1.00 to $10.00 and they
expire at various dates through February 2000.

During 1996, 59,500 warrants were issued relating to the subordinated
convertible debenture note.  No warrants were exercised or cancelled in 1996.

In 1995, warrants for 53,860 shares were exercised and warrants for 32,058
issued in prior years were cancelled.  During 1994, warrants for 50,000 shares
were issued to Dr. Fiebiger, who was elected to the Board of Directors in 1994,
at an exercise price of $3.63.  Warrants for an additional 5,918 shares were
given in lieu of cash to Dr. Fiebiger for consulting services valued at $16,800.
The exercise price for these warrants is $0.  During 1993, 50,000 warrants
issued to a Director were exercised at an exercise price of $1.00 and 30,000
warrants each were issued to two Directors at an exercise price of $2.06.


NOTE 11: SUBSEQUENT EVENTS

BANK LINE OF CREDIT
On January 6, 1997 the Company obtained a $5,000,000 revolving credit facility
that bears interest at the bank's prime rate (currently 8.25%) plus 2.25%, which
expires on January 31, 1999.  The line of credit agreement is secured by
substantially all of the Company's assets.  Under the agreement, the Company is
required to meet certain financial covenants involving


                                       18

capital spending levels and debt ratio, and may not declare or make any cash or
stock dividends.

1996 SUBORDINATED CONVERTIBLE DEBENTURE NOTES
During the first quarter of 1997, an aggregate of $3,970,000 ($3,150,000 of the
original principal of the Notes and $820,000 of accrued interest) has been
converted into 2,158,195 shares of the Company's Common Stock.  During the first
fourteen days of the second quarter of 1997, an aggregate of $256,000 ($200,000
of the original principal of the Notes and $56,000 of accrued interest) has been
converted into 170,502 shares of the Company's Common Stock.


1997 SUBORDINATED CONVERTIBLE DEBENTURE NOTES
On February 13, 1997, the Company completed a $5,000,000 private placement
financing agreement with investors, whereby the Company issued 6% subordinated
convertible debenture notes, which can be converted into shares of the Company's
Common Stock to be registered under Regulation D of the Securities Act of 1933.
The Company received $3,500,000 of the convertible subordinated debenture in
February 1997 and will receive the remaining $1,500,000 upon registration of
additional shares of the Company's Common Stock upon the effective filing of an
S-3 Registration Statement under the Securities Act of 1933.  Conversion rights
on these debentures  may be exercised at various dates, beginning on May 16,
1997, at discounts that range from 15% to 20% below the market price at the date
of conversion.  The amortized discount expense will be $1,250,000 and will be
expensed over the first 180 days upon receipt of the cash.  In addition, the
investors received warrants to purchase up to 500,000 additional shares of the
Company's Common Stock at $2.25 per share, subject to certain conditions.  
The debenture agreement specifies certain events of default, upon which the 
debentures would become immediately payable, including a delisting of the 
Company's Common Stock from the Nasdaq Stock Market (see Note 5).


QSS INC.
On April 14, 1997, the Company signed an agreement to sell its ownership in QSS
Inc., a joint venture established with QSS Ltd., for $3,500,000 cash.  Closing
is anticipated by April 30, 1997 (see Note 2).

                          INDEPENDENT AUDITORS' REPORT


TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF
ZYCAD CORPORATION

We have audited the accompanying consolidated balance sheets of Zycad
Corporation and its subsidiaries at December 31, 1996 and 1995, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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, such consolidated financial statements present fairly, in all
material respects, the financial position of Zycad Corporation and its
subsidiaries at December 31, 1996 and 1995, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1996 in conformity with generally accepted accounting principles.

As discussed in Note 5 to the Consolidated Financial Statements, the Company 
is required to continue trading on Nasdaq to comply with its debenture 
agreements. The Company is in discussions with Nasdaq concernings its 
eligibility to continue trading on the exchange. The outcome of this matter 
is uncertain, which raises substantial doubt about the Company's ability to 
remain in compliance with its debt agreements and continue as a going 
concern. Management's views concerning this matter are also described in Note 5.
The consolidated financial statements do not include any adjustments that 
might result from the outcome of this uncertainty.
