                                     PART I

ITEM 1.  BUSINESS

         Catalyst Semiconductor, Inc. ("Catalyst," the "Company" or
"Registrant") designs, develops and markets a broad range of nonvolatile
semiconductor memory products and is in the process of developing mixed signal
and micro-controller supervisory products. Nonvolatile memory ("NVM") retains
stored data when the system power is turned off and is therefore well suited for
a wide variety of applications in the computer, consumer electronics,
telecommunications, automotive, industrial control and instrumentation markets.
The Company was formed as a California corporation in October 1985 and was
reincorporated in Delaware in May 1993. The Company's principal offices are
located at 1250 Borregas Avenue, Sunnyvale, California 94089 and its telephone
number at that address is (408) 542-1000.

         The Company has sought to enhance its internal design and process
technology expertise through strategic relationships with leading semiconductor
manufacturers and currently subcontracts the fabrication of its semiconductor
wafers principally through Oki Electric Industry Co., Ltd. ("Oki"). These
relationships enable the Company to draw upon its foundries' expertise in high
volume semiconductor manufacturing. For example, the Company has integrated the
designs and processes for the manufacture of its Flash memory products with
Oki's fine line-width, high density CMOS processes used for high volume Dynamic
Random Access Memory ("DRAM") manufacture.

         The Company's business is highly cyclical and has been subject to
significant downturns at various times which have been characterized by reduced
product demand, production overcapacity, and significant erosion of average
selling prices. Throughout fiscal 1998, the market for certain FLASH and EEPROM
devices, which compromise the majority of Catalyst's business, experienced an
excess market supply relative to demand which resulted in a significant
downward trend in prices. The Company could continue to experience a downward
trend in product pricing which could further adversely affect the Company's
operating results.

         The Company's recent operating results have consumed substantial
amounts of cash. The reduction in cash also placed restrictions on wafer
purchases which, during the fourth quarter of 1998, resulted in the
cancellation of some customer sales orders. In May 1998, the Company received
net proceeds of $1.5 million from the sale of 1,500,000 shares of its Common
Stock in a private placement. Management believes, however, that it will
require additional cash from similar or related private placements or other
sources of liquidity to meet the Company's projected working capital and other
cash requirements for fiscal 1999, and is currently pursuing these sources of
liquidity.

         As a result of these circumstances, the Company's independent
accountants' opinion on the consolidated financial statements includes an
explanatory paragraph indicating that these matters raise a substantial doubt
about the Company's ability to continue as a going concern.

         As of April 30, 1998, the Company had approximately $3.2 million, and
currently has approximately $1.4 million, of secured loans owing to its bank. As
a result of the Company's financial condition and results of operations, the
bank has determined that the Company is in default under various provisions of
the loan agreement entitling the bank to terminate the loan agreement and
declare the loans immediately due and payable. Although the Company has obtained
a letter of forbearance from the bank taking any action with respect to existing
defaults, such forbearance only extends until September 30, 1998 and only as to
the specified defaults claimed through June 30, 1998. The Company is seeking to
persuade the bank not to take action on the events of default and not to declare
the loan due and payable. In that regard the Company is seeking to obtain equity
or other funding to increase the cash available for operations and other
purposes. There can be no assurance that such efforts to obtain funding will be
successful or, if successful, that the bank will continue to forbear action on
or otherwise waive the existing defaults. If the Company's efforts are
unsuccessful, the bank is likely to declare the loans due and payable. Under
such circumstances the Company would be unable to continue operations which
would result in bankruptcy. The Company is also indebted to other creditors in
the amount of approximately $13.4 million. Continued operation of the Company
would also require such other lenders to forbear taking action or waiving
defaults under such other debt. Moreover it is anticipated that any continued
forbearance by the bank would require such other lenders to take similar action
under the other loans. In addition, although the Company is current on its lease
payments under the lease of its headquarters facility, as a result of its
financial condition, the Company is in violation of certain terms of its lease.
Similar violations have resulted under certain equipment lease agreements.

         The Company's recent operating results have been substantially lower
than expected. Total revenues for the quarter and the fiscal year ended April
30, 1998 were $4.8 million and $34.6 million, respectively, compared to
revenues of $9.0 million and $47.1 million for the comparable periods of the
prior year. In addition, the Company incurred net losses for the quarter and
for the year ended April 30, 1998 of $10.1 million and $18.9 million,
respectively, compared to net losses of $1.1 million and $4.1 million for the
comparable periods in the prior year. The Company's last profitable year was
the fiscal year ended April 30, 1996. For over two years, the Company has
experienced significant negative cash flow from operations and investing
activities. The Company has taken many steps to reduce its operating expenses
including reducing its headcount from 71 in December, 1996 to 42 in April 1998.
Although reductions in headcount could help the Company meet its operating
expense objectives, such reductions could adversely affect the Company's sales,
marketing and product development efforts. The Company anticipates that negative
cash flow from operations will continue for the foreseeable future. There can
be no assurance that the Company can generate revenue growth, or that any
revenue growth that is achieved can be sustained. To the extent that increases
in such operating expenses precede and are not subsequently followed by
increased revenues, the Company's business, results of operations and financial
condition would be materially adversely affected. There can be no assurance
that the Company will ever achieve or sustain profitability.

         The Company markets its products through a direct sales force and a
worldwide network of independent distributors and sales representatives. For the
year ended April 30, 1998, international sales represented 64% of product sales.
End user customers of the Company's products include Compaq, Fujitsu, IBM,
Matsushita Communications, Maxtor, Motorola, Siemens and Sony.

INDUSTRY BACKGROUND

         There are two general classes of semiconductor memories incorporated
into electronic systems, volatile memory and nonvolatile memory. The principal
distinguishing characteristic between the two classes is that volatile memory
devices require a continuous application of power to retain data, while NVM
devices do not. Among volatile memory devices, DRAMs are the most prevalent,
because they are capable of high-speed data transfer, feature high density
circuitry and can be manufactured at relatively low cost. DRAMs are used
primarily as the main memory in computers for temporary storage of application
program data while the system is operating. NVM devices, in contrast, are used
by computers and electronic systems primarily to store system-critical data when
the power to the system is turned off. The continuous memory capability of NVM
renders these devices well-suited for a wide range of applications in the
computer, consumer electronics, telecommunications, automotive, industrial
control and instrumentation markets. NVM devices are used to store essential
data such as PC BIOS software, which regulates the flow of data to and from
system peripherals such as the keyboard and monitor and disk drives. In
addition, NVM devices that can be programmed and reprogrammed in the system are
used to store user-selected system configurations in consumer electronics
devices such as preset stations in automobile radios and to store numbers in
cellular telephones. NVM devices have generally not been used for computer main
memory applications because historically they have been more expensive, provided
slower performance and were more costly to produce than volatile memory such as
DRAMs.

         The different NVM semiconductor devices which the Company sells are
reprogrammable NVM memory such as electrically erasable programmable read only
memory ("EEPROM"), nonvolatile random access memory ("NVRAM"); and Flash memory.
Each successive generation of NVM memory offers increasing functionality,
flexibility and performance.



                                      -3-
<PAGE>   4


         The following NVM devices are currently available from various
suppliers in the industry:

         EEPROMs. EEPROMs can be erased and reprogrammed electrically within the
system, eliminating the need for physical removal, as required by EPROMs. On
"full-featured" EEPROMs, which have on-chip error correction capabilities that
enhance system reliability, individual bytes or segments of the stored data can
be erased and rewritten thousands of times. These features generally offer
greater flexibility to systems designers than EPROMs. EEPROMs are used to store
system-critical information which needs to be updated on a periodic basis. This
includes control panel settings and other user-configurable system parameters in
consumer devices, cache memory for disk drives, and system protocols and stored
telephone numbers in cellular telephones, facsimile machines and other
telecommunications devices. EEPROMs are generally available in two
configurations, serial EEPROM devices, which transmit data through a single
input-output port, and parallel EEPROMs, which transmit data via multiple ports
concurrently. Each cell of an EEPROM (the discrete area on the device in which
one bit is stored) consists of two transistors, one to store data and one to
permit the cell to be selected when erasing data, as compared to the single,
storage transistor of an EPROM. EEPROMs can be modified to be utilized as
programmable erasable read only memory (PEROM) devices for 5-volt FLASH
applications involving sector-by-sector data read and write. EEPROMs are more
expensive to produce than EPROMs, due to their more complex circuitry.

         NVRAMs. NVRAMs consist of a Static Random Access Memory ("SRAM") device
and an EEPROM incorporated in a single semiconductor die. This enables the
device to provide both the high speed data transfer rates and read/write rates
typical of volatile SRAMs and the memory retention of NVMs when the system power
is off. However, the complexity of NVRAM devices, which typically utilize 8
transistors per cell, makes them too costly for most commercial applications.
Accordingly, NVRAMs are generally limited in application to critical,
high-performance systems, such as antilock braking systems.

         Flash Memory. Flash EEPROMs, or Flash memories, combine the benefits of
high-speed data alterability and data transfer rates and, potentially, the low
cost manufacturability of volatile memory, with the flexibility and continuous
data retention of NVM. Flash memory products can potentially be manufactured
with storage densities as great as DRAM densities and thereby achieve
manufacturing costs approaching the low cost of DRAMs. In addition, the
architecture of Flash memory potentially permits data alterability and transfer
rates as fast as DRAMs. Flash memory exhibits certain limitations as compared to
DRAMs, including a finite life span of read/write cycles, which limits its use
in computer main memory applications. However, Flash memory is being designed
into a wide variety of applications beyond the traditional application of NVM in
fixed program and data storage, and to applications in dynamic data storage due
to its nonvolatility, high storage densities, rapid access speed and decreasing
cost.

PRODUCTS AND APPLICATIONS

         Catalyst provides a broad range of NVM products, including serial and
parallel EEPROMs, Flash memories, NVRAMs and mixed signal products. The
Company's principal product lines are as follows:

         Serial EEPROM. The Company offers a broad range of serial EEPROM
products compatible with the three popular industry standard bus interface
protocols: the Inter-Integrated Circuit ("I2C") bus interface of Philips
Electronics, the Microwire interface protocol of National Semiconductor and the
Serial Peripheral Interface ("SPI") bus protocol. Additionally, Catalyst offers
4-wire bus interface protocol type products and secure access designed for
applications requiring security lock for data protection. Products are offered
in wide density (1K to 128K) and voltage (1.8V to 6V) ranges. Serial EEPROM
products are used in many applications to store user reconfigurable data. Some
of the more common applications are disk drives, modems, cellular phones, VCRs,
CD players, hearing aids, PCMCIA cards, cordless phones, laser printers,
computers and pagers.

         Parallel EEPROM. Parallel EEPROMs transfer data in multiple bits,
generally eight bits at a time. They provide faster transfer rates than serial
EEPROMs, which transfer data through a single port. Parallel EEPROMs are more
costly than serial EEPROMs and, accordingly, are used primarily in high
performance applications. Catalyst offers both standard 5 volt-only and 3.3
volt-only parallel EEPROMs to meet battery operated application



                                      -4-
<PAGE>   5


requirements. Parallel EEPROMs are primarily used in applications such as POS
terminals, industrial controllers, LAN adapters, telecommunication switches,
cellular phones and modems.

         Flash Memory. The Company currently offers Intel-licensed, 12-volt
Flash memory devices in densities ranging from 256 kilobit to 2 megabit (Mb).
The Company's BIOS Flash family is targeted toward personal computer OEMs for
BIOS code storage. This family includes Intel-licensed boot block and bulk erase
technologies available in 1 Mb, 1.5 Mb and 2 Mb densities. The 1.5 Mb devices
are unique to Catalyst. These products were developed to exploit the trend for
PC BIOS requirements that exceed 1 Mb but do not require a 2 Mb solution. The
Company's 1 Mb wordwide (x16) Flash memory product is targeted at disk drive
applications. There can be no assurance that the Company will receive additional
significant orders for this product or that it will achieve more wide-spread
market acceptance.

         NVRAMs. NVRAMs consist of an SRAM and an EEPROM incorporated on a
single semiconductor die. NVRAMs provide superior performance over other NVM
products and are ideal for applications that require high speed read/write
operations with nonvolatile memories, including parallel processing controllers
for LANs and antilock braking systems.

         Mixed Signal/Micro-Controller Supervisory Products. The Company
designs, manufactures and markets selected mixed signal and has under current
development micro-controller supervisory products using embedded EEPROM
technologies for specialized applications including radio frequency tags for
contactless security and access control, freight lading billing systems, data
collection and general micro-controller applications. These products are based
on the Company's NVM expertise and digital/analog mixed signal design.

SALES AND DISTRIBUTION

         The Company markets its products through a direct sales force and a
network of independent distributors and sales representatives. In addition to
its Sunnyvale headquarters facility, the Company maintains domestic sales
offices in Arizona, Florida and Georgia and international sales offices in
England and Taiwan. Sales offices support both OEM customers and distributors.
In addition, Nippon Catalyst K.K., the Company's subsidiary in Japan, works
closely with the Company's manufacturing subcontractors and Japanese
distributors.

         The Company seeks to develop strategic relationships with major OEM and
other customers. The Company offers a broad range of NVM devices compatible with
the most common industry standards, and also works closely with customers to
provide semi-custom solutions to address individual customers' needs. In fiscal
1998, the Company shipped products directly or through its distribution network
to customers in the computer, consumer electronics, telecommunications,
automotive, data communication and other industries. OEM customers of the
Company's products include Compaq, Fujitsu, IBM, Matsushita Communications,
Motorola, Siemens and Sony.

         During fiscal years 1998, 1997 and 1996, the only customer which
represented more than ten percent of Catalyst's product revenue was Marubun
Corporation, a Japanese distributor (21%, 14% and 12%, respectively). In
December 1997, Marubun resigned as a distributor effective in or about March
1998. International product sales represented approximately 64%, 63% and 60% of
the Company's product sales in fiscal 1998, 1997 and 1996. International sales
are primarily billed in U.S. dollars. Due to the magnitude of its international
sales, the Company is subject to the risks of conducting business
internationally, including unexpected changes in regulatory requirements,
fluctuations in the U.S. dollar, which could increase the sales price of the
Company's products in local currencies, tariffs and other barriers and
restrictions, and the burdens of complying with a variety of foreign laws.

         The Company generally does not recognize revenue on shipments to its
distributors until the distributor resells the Company's products. In addition,
as is common in the semiconductor industry, the Company grants price protection
to distributors, in an amount equal to the difference between the price
originally charged and the reduced price, for products held in inventory by the
distributor at the time of a price reduction. From time to time, distributors
are also granted credit on an individual basis for Company-approved price
reductions on specific transactions.

MANUFACTURING

         The Company subcontracts the manufacture of all of its products through
independent semiconductor manufacturers, primarily Oki. The Company has designed
its proprietary circuit designs and fabrication processes to operate within the
overall semiconductor manufacturing processes of its contract manufacturers.
Various of the Company's designs have been integrated with Oki's CMOS processes
utilized in high volume production of DRAMs. The Company also endeavors to
develop its processes in a manner that permits the manufacture of its products
in the fabrication facilities of different semiconductor manufacturing
suppliers. If the Company were forced to switch manufacturing from Oki, its
production and delivery of products would be delayed which could adversely
affect the Company's business, financial condition and results of operations.

         Manufacturing semiconductor products is highly complex and sensitive to
a wide variety of factors including the level of contaminants in the
manufacturing environment, impurities in the materials used and the performance
of personnel and equipment. While the Company believes that it has suppliers
willing to provide an adequate wafer supply to meet its currently anticipated
needs, there can be no assurance that the Company will receive sufficient
quantities of wafers at favorable prices on a timely basis, if at all. As is
typical in the semiconductor industry, the Company's outside foundries have from
time to time experienced lower than anticipated production yields. There can be
no assurance that manufacturing problems will not occur in the future. The loss
of Oki as a supplier, any prolonged inability to obtain adequate yields or
deliveries from Oki, UMC or other subcontractors or manufacturers, or any other
circumstance that would require the Company to seek alternative sources of
supply, could delay shipments and have a material adverse effect on the
Company's operating results. The Company currently purchases wafer supplies
under an arrangement with Oki while the parties are negotiating a definitive
agreement. The Company also has a purchase agreement with UMC which runs through
February 2006. Due to declining Flash bookings and other circumstances, the
Company has not ordered any wafers from UMC since December 1997. The Company's
ability to purchase wafers is also subject to having sufficient cash or credit
to pay for those wafers. The Company's financial condition has impaired the
Company's ability to purchase necessary wafer supplies. See "Management's
Discussion and Analyses of Financial Condition and Results of
Operations--Results of Operations," and "--Liquidity and Capital Resources."

         The Company performs circuit assembly and tests primarily through
subcontractors located in Southeast Asia. In the assembly process, the wafers
are separated into individual dies, which are then assembled into packages and
tested in accordance with procedures developed by the Company. Following
assembly, the packaged devices are further tested and inspected pursuant to the
Company's quality assurance program prior to shipment to customers. While the
timeliness, yield and quality of semiconductor deliveries from the Company's
suppliers have been acceptable to date, there can be no assurance that
manufacturing problems will not occur in the future. Any prolonged inability to
obtain adequate yields or deliveries from these manufacturers, or any other
circumstance that would require the Company to seek alternate sources of supply,
could delay shipments. Any significant delays would have an adverse effect on
the Company's operating results. The Company has concerns with the financial
viability of its primary test and assembly contractor. Although the Company is
exploring alternative contractors, there can be no assurance that it will be
able to obtain such alternative services or that the Company will have adequate
test and assembly facilities available. Failure to have such services available
would have a material effect on the Company's business, financial condition and
results of operations.

         As a result of the Company's dependence on foreign subcontractors and
test facilities, the Company's business is subject to the risks generally
associated with doing business abroad, such as fluctuations in currency exchange
rates, foreign government regulations, political unrest, disruptions or delays
in shipments and changes in economic conditions in countries in which the
Company's manufacturing and assembly and test sources are located. Due to the
Company's cash restrictions, the Company may not be able to maintain payments
to wafer and other subcontractor creditors which are within these supplier's
credit terms. Accordingly, these suppliers may restrict the Company's future
purchases and accordingly may restrict sales of the Company's products.

RESEARCH AND DEVELOPMENT

         The Company continues to invest substantial sums in research and
development to improve its fabrication processes and develop additional products
with higher performance and reliability, lower voltage requirements, smaller die
sizes and improved manufacturability. The Company's development efforts include
the development of successive generations of its EEPROM and Flash memory
products, scaled to smaller geometries and mixed signal and micro-controller
supervisory circuits with embedded EEPROM technologies. As of April 30, 1998,
the



                                      -6-
<PAGE>   7
Company employed 13 persons in research and development activities. The Company
invested $4.5 million, $5.8 million and $4.4 million in research and development
activities in fiscal 1998, 1997 and 1996, respectively. In addition, the Company
has hired the services of Essex S.A., an independent contractor in Bucharest,
Romania, to perform design services and test program development on behalf of
the Company at market rates. Mr. Vanco is a majority shareholder of Essex. As of
April 30, 1998, Essex employed approximately 12 engineers to perform the
services on behalf of Catalyst. 

PATENTS AND LICENSES

         As of April 30, 1998, the Company owned fifteen U.S. patents, one
international patent and had one additional U.S. patent application pending. The
Company intends to continue to seek patents on its inventions used in its
products and manufacturing processes. The process of seeking patent protection
can be expensive and time consuming. There can be no assurance that patents will
issue from pending or future applications or that, if patents are issued, they
will provide meaningful protection or other commercial advantage to the Company.
Moreover, there can be no assurance that any patent rights will be upheld in the
future or that the Company will be able to preserve any of its other
intellectual property rights.

         In the semiconductor industry it is typical for companies to receive
notices from time to time alleging infringement of patents or other intellectual
property rights of others. There can be no assurance that the Company will not
receive any such notification or that proceedings alleging infringement of
intellectual property rights will not be commenced against the Company in the
future. In such event, there can be no assurances that the Company could obtain
any required licenses of third party intellectual property rights or could
obtain such licenses on commercially reasonable terms. Failure to obtain a
license in any such event could require the Company to cease production of its
products until the Company develops a non-infringing design or process.
Moreover, the cost of litigation of any such claim or damages resulting
therefrom could be substantial and could materially and adversely affect the
Company's business, financial condition and results of operations.

         The Company has entered into cross license agreements with Oki and
Seiko granting them nontransferable rights to produce certain products, in
exchange for royalty payments. See "Manufacturing." The Company is not currently
receiving any royalties under these licenses. In August 1995, the Company
entered into an agreement with Intel Corporation which provides Catalyst with a
license to Intel's Flash memory and EEPROM technology in exchange for royalty
payments. The Company is currently in arrears on approximately $1 million of
royalties due to Intel. Should Intel cancel the license for the Company's
failure to pay such royalties, the Company's ability to produce its products
would be materially adversely affected which would result in a material adverse
effect on the Company's business, financial condition and results of operations.
In addition, in February 1996, the Company also entered into an agreement with
UMC, granting UMC rights to produce certain products in exchange for the
provision of certain wafer capacities and certain other license rights. In
addition, as a part of such arrangement UMC purchased 650,000 shares of the
Company's Common Stock for an aggregate cash consideration of $3.7 million.

COMPETITION

         The semiconductor industry is intensely competitive and has been
characterized by price erosion, rapid technological change and product
obsolescence. The Company competes with major domestic and international
semiconductor companies, many of whom have substantially greater financial,
technical, marketing, distribution and other resources than the Company.

         The Company's more mature products, such as EEPROM devices, compete on
the basis of product performance, price and customer service. The Company
believes it competes successfully with respect to each of these competitive
attributes. Price competition is significant and expected to continue. Principal
competitors with respect to the Company's EEPROM products currently include
SGS-Thomson, National Semiconductor, Atmel and Xicor, as well as the Company's
strategic manufacturing partner Oki, all of which have substantially greater
resources than the Company.

         The market for Flash memory products has been characterized by long
production cycles, irregular yields, competing technologies and, particularly in
fiscal 1997 and fiscal 1998, intense price competition. There can be no



                                      -7-

assurance that the Company will be able to compete successfully in the future
against its competitors for Flash products business.

EMPLOYEES

         As of April 30, 1998, the Company had 42 employees, of whom 13 were
engaged in research and development. The Company's future success will depend on
its ability to attract, train, retain and motivate highly qualified employees,
who are in great demand. The Company's employees are not represented by any
collective bargaining organization, and the Company has never experienced any
work stoppage. The Company believes that its employee relations are good.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

         THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH THE
CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO INCLUDED IN THIS ANNUAL
REPORT ON FORM 10-K. IN ADDITION, IN ORDER TO TAKE ADVANTAGE OF THE "SAFE
HARBOR" PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995, THE
COMPANY HEREBY NOTIFIES READERS THAT THE FACTORS SET FORTH IN "CERTAIN FACTORS
THAT MAY AFFECT THE COMPANY'S FUTURE RESULTS" AS SET FORTH BELOW IN THIS ITEM 7,
AS WELL AS OTHER FACTORS, IN THE PAST HAVE AFFECTED AND IN THE FUTURE COULD
AFFECT THE COMPANY'S ACTUAL RESULTS, AND COULD CAUSE THE COMPANY'S RESULTS FOR
FUTURE PERIODS TO DIFFER MATERIALLY FROM THOSE EXPRESSED IN ANY FORWARD LOOKING
STATEMENTS MADE BY OR ON BEHALF OF THE COMPANY, INCLUDING WITHOUT LIMITATION
THOSE MADE IN THIS REPORT.

OVERVIEW

         Catalyst Semiconductor, Inc., incorporated October 8, 1985, designs,
develops and markets nonvolatile memory semiconductor products including Serial
and Parallel EEPROMs and Flash memory. Revenues are derived from sales of
semiconductor products designed by the Company and manufactured by other
companies.

         The Company's business is highly cyclical and has been subject to
significant downturns at various times which have been characterized by reduced
product demand, production overcapacity, and significant erosion of average
selling prices. Throughout fiscal 1998, the market for certain FLASH and EEPROM
devices, which comprise the majority of Catalyst's business, experienced an
excess market supply relative to demand which resulted in a significant downward
trend in prices. The Company could continue to experience a downward trend in
product pricing which could further adversely affect the Company's operating
results.

         The Company's recent operating results have consumed substantial
amounts of cash. The reduction in cash has also placed restrictions on wafer
purchases which, during the fourth quarter of 1998, resulted in the cancellation
of some customer sales orders. In May 1998, the Company received net proceeds of
$1.5 million from the sale of 1,500,000 shares of its Common Stock in a private
placement. Management believes, however, that it will require additional cash
from similar or related private placements or other sources of liquidity to meet
the Company's projected working capital and other cash requirements for fiscal
1999, and is currently pursuing these sources of liquidity.

         As a result of these circumstances, the Company's independent
accountants' opinion on the consolidated financial statements includes an
explanatory paragraph indicating that these matters raise substantial doubt
about the Company's ability to continue as a going concern.

RESULTS OF OPERATIONS

         FISCAL YEAR ENDED APRIL 30, 1998 COMPARED TO FISCAL YEAR ENDED APRIL
30, 1997

         Revenues. Total revenues consist primarily of net product sales. A
substantial portion of net product sales has been made through independent
distributors. Revenue from product sales to original equipment manufacturers and
from sales to distributors who have no, or limited, product return rights and no
price protection rights, is recognized upon shipment net of allowances for
estimated returns. When distributors have rights to return products or price
protection rights, the Company defers revenue recognition until the distributor
sells the product to the customer. Total revenues decreased by 27% to $34.6
million in fiscal 1998 from $47.1 million in fiscal 1997. The decrease was
primarily attributable to price erosion caused by excess supply and other
adverse industry-wide conditions. Additionally, the Company was unable to
purchase sufficient wafers during the fourth quarter of fiscal 1998 due to lack
of working capital. The Company is reliant upon receiving and fulfilling orders
within the same quarter to meet or exceed its current revenue levels. A
continuation of weak demand, capital deficiencies and price erosion for the
Company's products could lead to continued poor operating results. In May and
June of 1998, the company received substantial cancellations of the backlog
existing at fiscal year end. International sales contributed 64% of net product
sales in fiscal 1998 as compared to 63% in fiscal 1997.



                                      -12-
<PAGE>   13

         Gross Profit (Loss). Gross loss for fiscal 1998 was $4.4 million, or a
gross loss of 13% of revenues, compared to gross profit of $10.4 million, or 22%
of revenues, for fiscal 1997. The decreases in absolute dollars were primarily
attributable to reduced revenues and $7.5 million in charges taken in the third
and fourth quarters of fiscal 1998. These charges were taken primarily to adjust
the value of certain inventories to reflect reductions in current market pricing
below the cost to produce the inventory and to adjust the value of certain
inventories for which the Company has quantities that exceed forecasted demand.
Gross margins were also adversely affected by excess supplies of competitive
products and other adverse industry-wide conditions, lower than anticipated
yields achieved on the Company's 0.6 micron version of its Flash memory devices,
rework charges incurred to re-mark and re-test certain products in preparation
of shipping those products to customers of the Company, and expedite charges
incurred to ensure that delivery was made in time to meet customer schedules.

         Research and Development. Research and development ("R&D") expenses
consist principally of salaries for engineering, technical and support
personnel, depreciation of equipment, and the cost of wafers used to evaluate
new products and new versions of current products. R&D expenses decreased 22% to
$4.5 million in fiscal 1998 from $5.8 million in fiscal 1997. The decrease in
dollars was primarily attributable to decreases in R&D personnel costs. As a
percentage of revenues, R&D expenses increased to 13% from 12%. This increase
was primarily attributable to decreased sales.

         Selling, General and Administrative. Selling, general and
administrative ("SG&A") expenses consist principally of salaries for sales,
marketing and administrative personnel, commissions, promotional activities and
directors and officers ("D&O") insurance. SG&A expenses increased 8% to $9.1
million in fiscal 1998 from $8.4 million in fiscal 1997. This increase was
primarily attributable to bad debt expenses and severance accruals. As a
percentage of revenues, SG&A expenses increased to 26% from 18%. The increase in
SG&A as a percentage of revenues was attributable to absolute spending
increasing while revenues decreased.

         Net Interest Expense. Net interest expense increased by 313% to
$847,000, or 2% of revenues, in fiscal 1998, as compared to $205,000, or .4% of
revenues, in fiscal 1997. The increase was primarily attributable to increased
average outstanding borrowings. Increased borrowings were not offset by
increased balances in interest bearing cash accounts.

         Income Tax Provision. As a result of the Company's loss, the provision
for income taxes remained at zero in fiscal 1998.

         As of April 30, 1998 the Company had available net operating loss
carryforwards of approximately $37.6 million and credit carryforwards of
approximately $1.0 million for federal tax purposes, which begin to expire in
fiscal 2001. Availability of the net operating loss and general business credit
carryforwards may potentially be reduced in the event of substantial changes in
equity ownership.

         FISCAL YEAR ENDED APRIL 30, 1997 COMPARED TO FISCAL YEAR ENDED APRIL
30, 1996

         Revenues. Total revenues decreased by 22% to $47.1 million in fiscal
1997 from $60.2 million in fiscal 1996. The decrease was primarily attributable
to price erosion caused by excess supply and other adverse industry-wide
conditions. International sales contributed 63% of net product sales in fiscal
1997 as compared to 60% in fiscal 1996.

         Gross Profit. Gross profit decreased by 42% to $10.4 million in fiscal
1997 from $18.0 million in fiscal 1996. The decrease was primarily attributable
to price erosion caused by excess supply and other adverse industry-wide
conditions. Lower cost versions of the Company's Serial and Parallel EEPROMs,
produced on 0.8 micron processes, and Flash memory devices, produced on 0.6
micron processes, were in design or already released to production.

         Research and Development. R&D expenses increased 31% to $5.8 million in
fiscal 1997 from $4.4 million in fiscal 1996. As a percentage of revenues, R&D
expenses increased to 12% from 7%. The increase was primarily attributable to
increases in R&D personnel costs, facility costs (related to the Company's move
into a new facility in August 1996), depreciation expense, other outside
services (primarily the Company's independent contractors for



                                      -13-

engineering services in Romania) and higher material costs for wafers being used
to evaluate new products and new versions of current products.

         Selling, General and Administrative. SG&A expenses decreased 13% to
$8.4 million in fiscal 1997 from $9.7 million in fiscal 1996. This decrease was
primarily attributable to decreases in commissions due to lower revenues and
personnel costs. As a percentage of revenues, SG&A expenses increased to 18%
from 16%. This increase was attributable to absolute spending decreasing at a
rate lower than the revenue decrease.

         Net Interest Expense. Net interest expense was $205,000 in fiscal 1997,
as compared to $225,000 in fiscal 1996. Increased borrowings were offset by
increased balances in interest bearing cash accounts.

         Income Tax Provision. As a result of the Company's loss, the provision
for income taxes decreased from $48,000 in fiscal 1996 to zero in fiscal 1997.

LIQUIDITY AND CAPITAL RESOURCES

         Total cash (including $5.8 million of restricted cash) decreased $1.7
million to $6.3 million as of April 30, 1998 from $7.9 million as of April 30,
1997. The decrease was primarily attributable to net cash used to purchase
equipment and repay debt and capital lease obligations. As of April 30, 1998,
$5.8 million of the total cash was pledged as security on letters of credit
required by certain of the Company's wafer foundries. Net cash provided by
operating activities totaled $0.3 million during fiscal 1998. This was primarily
attributable to net operating losses offset by a change in working capital
amounts.

         The Company has approximately $3.2 million of secured loans owing to
its bank. As a result of the Company's financial condition and results of
operations, the bank has determined that the Company is in default under various
provisions of the loan agreement entitling the bank to terminate the loan
agreement and declare the loans immediately due and payable. Although the
Company has obtained a letter of forbearance from the bank taking any action
with respect to existing defaults, such forbearance only extends until September
30, 1998 and only as to the specified defaults claimed through June 30, 1998.
The Company is seeking to persuade the bank not to take action on the events of
default and not to declare the loan due and payable. The Company is seeking to
renegotiate a further extension of such forbearance. Although the Company is
seeking to remedy its noncompliance or renegotiate the terms of the loan
agreement, there can be no assurance that the Company will be successful in its
efforts and that the bank will not accelerate all amounts due under the bank
agreement.

         On February 15, 1997, a vendor loaned $1.2 million to the Company in
settlement of billings for assembly and test services totaling the same amount.
The loan bears interest at 18% and was due and payable on May 15, 1998, but has
an arrangement to extend it to October 15, 1998.

         The Company is currently seeking additional equity or debt financing to
address its working capital needs and to provide funding for capital
expenditures. There can be no assurances, however, that financing will be
available on terms acceptable to the Company, if at all. If the Company is not
successful in raising additional capital, in view of the uncertainties relating
to arrangements with its bank and other lenders, the Company can not reasonably
assess how long its current cash balances, cash generated from operations and
borrowings available under any remaining loans or lines of credit and from
equipment financing, even with substantial reductions in operating expenses and
capital expenditures, will permit the Company to continue operations.

CERTAIN FACTORS THAT MAY AFFECT THE COMPANY'S FUTURE RESULTS

         THE COMPANY DESIRES TO TAKE ADVANTAGE OF CERTAIN PROVISIONS OF THE
PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995, ENACTED IN DECEMBER 1995 (THE
"REFORM ACT") THAT PROVIDES A "SAFE HARBOR" FOR FORWARD-LOOKING STATEMENTS MADE
BY OR ON BEHALF OF THE COMPANY. THE COMPANY HEREBY CAUTIONS STOCKHOLDERS,
PROSPECTIVE INVESTORS IN THE COMPANY AND OTHER READERS THAT THE FOLLOWING
IMPORTANT FACTORS, AMONG OTHERS, IN SOME CASES HAVE AFFECTED, AND IN THE FUTURE
COULD AFFECT, THE COMPANY'S STOCK PRICE OR CAUSE THE COMPANY'S ACTUAL RESULTS
FOR THE FISCAL YEAR ENDING APRIL 30, 1999, FOR THE FISCAL QUARTER ENDING JULY
31, 1998, AND FUTURE FISCAL YEARS AND



                                      -14-
<PAGE>   15


QUARTERS TO DIFFER MATERIALLY FROM THOSE EXPRESSED IN ANY FORWARD-LOOKING
STATEMENTS, ORAL OR WRITTEN, MADE BY OR ON BEHALF OF THE COMPANY.

         The Company's business and future operating results are subject to
potential fluctuations due to a number of factors including the following:

         Defaults under Outstanding Loans; Risk of Bankruptcy. The Company has
approximately $3.4 million of secured loans owing to its bank. As a result of
the Company's financial condition and results of operations, the bank has
determined that the Company is in default under various provisions of the loan
agreement entitling the bank to terminate the loan agreement and declare the
loans immediately due and payable. Although the Company has obtained a letter of
forbearance from the bank taking any action with respect to existing defaults,
such forbearance only extends until September 30, 1998 and only as to the
specified defaults claimed through June 30, 1998. The Company is seeking to
persuade the bank not to take action on the events of default and not to declare
the loan due and payable. In that regard the Company is seeking to obtain equity
or other funding to increase the cash available for operations and other
purposes. There can be no assurance that such efforts to obtain funding will be
successful or, if successful, that the bank will continue to forbear action on
or otherwise waive the existing defaults. If the Company's efforts are
unsuccessful, the bank is likely to declare the loans due and payable. Under
such circumstances the Company would be unable to continue operations which
would result in bankruptcy. The Company is also indebted to other creditors in
the amount of approximately $13.4 million. Continued operation of the Company
would also require such other lenders to forbear taking action or waiving
defaults under such other debt. Moreover it is anticipated that any continued
forbearance by the bank would require such other lenders to take similar action
under the other loans. In addition, although the Company is current on its lease
payments under the lease of its headquarters facility, as a result of its
financial condition, the Company is in violation of certain terms of its lease.
Similar violations have resulted under certain equipment lease agreements.

         Need for Additional Capital. The Company has incurred significant
losses and experienced significant negative cash flow from operations for over
two years. Such negative cash flow has significantly reduced the Company's
available capital. If the Company is successful in having its lenders agree to
waive or forbear actions on defaults under existing loans or to renegotiate the
terms of such loans to enable the Company to keep such loans outstanding, or
perhaps as a condition to such waivers, the Company will need to obtain
additional capital. If the Company is not successful in raising additional
capital, in view of the uncertainties relating to arrangements with its bank and
other lenders, the Company can not reasonably assess how long its current cash
balances, cash generated from operations and borrowings available under any
remaining loans or lines of credit and from equipment financing, even with
substantial reductions in operating expenses and capital expenditures, will
permit the Company to continue operations. There can be no assurance that the
Company will generate sufficient revenue to fund its operations in the absence
of additional funding sources. The Company has pursued and continues to pursue
measures designed to reduce expenses and conserve cash such as deferring
payments to vendors and other suppliers, headcount reductions, deferrals of
planned expenditures, other expense reductions and other measures. Although such
activities help preserve cash and enable the Company to continue operations, the
lack of available capital hinders the Company's ability to continue
manufacturing, sales, product development and other ongoing operational
activities necessary to generating revenues. Such activities can have a
material, adverse affect on the Company's business, financial condition and
operating results. Furthermore, to the extent the Company suffers further
adverse effects to its revenues or margins because of delays in new product
introductions, price competition or other competitive factors, the Company's
cash position and its business, operating results and financial condition will
be further adversely affected.

         The Company is currently seeking additional equity or debt financing to
address its working capital needs and to provide funding for capital
expenditures. The Company's fund raising efforts to date have not been
successful and there can be no assurance that such funding will be available at
acceptable terms, if at all. If the Company is successful in raising funds
through the issuance of equity securities, existing stockholders of the Company
would likely experience substantial dilution, or the securities may have rights,
preferences or privileges senior to those of the Company's Common Stock. If
adequate funds are not available or are not available on acceptable terms,
further reductions in its operating expenses and capital expenditures would be
required to continue operations either of which could have a material adverse
effect on the Company's business, operating results and financial condition.



                                      -15-
<PAGE>   16
         Recent Operating Results; Anticipated Future Losses. The Company's
recent operating results have been substantially worse than expected. Total
revenues for the quarter and the fiscal year ended April 30, 1998 were $4.8
million and $34.6 million, respectively, compared to revenues of $9.0 million
and $47.1 million for the comparable periods of the prior year. In addition, the
Company incurred net losses for the quarter and for the year ended April 30,
1998 of $10.1 million and $18.9 million, respectively, compared to net losses of
$1.1 and million and $4.1 million for the comparable periods in the prior year.
The Company's last profitable year was the fiscal year ended April 30, 1996. For
over two years, the Company has experienced significant negative cash flow from
operations. The Company has taken many steps to reduce its operating expenses
including reducing its headcount from 71 in December 1996 to 42 in April 1998.
Although reductions in headcount could help the Company meet its operating
expense objectives, such reductions could adversely impact the Company's sales,
marketing and product development efforts. The Company anticipates that negative
cash flow from operations will continue for the foreseeable future. There can be
no assurance that the Company can generate revenue growth, or that any revenue
growth that is achieved can be sustained. To the extent that increases in such
operating expenses precede and are not subsequently followed by increased
revenues, the Company's business, results of operations and financial condition
would be materially adversely affected. There can be no assurance that the
Company will ever achieve or sustain profitability.

         Fluctuations in Operating Results. The Company's operating results have
historically been and in future quarters may be adversely affected or otherwise
fluctuate due to factors such as timing of new product introductions and
announcements by the Company and its competitors, fluctuations in customer
demand for the Company's products, volatility in supply and demand affecting
market prices generally (such as the increases in supply of competitive products
and significant declines in average selling prices experienced by the Company in
the fiscal years ended April 30, 1998 and 1997), increased expenses associated
with new product introductions or process changes, increased expenditures
related to expanding the Company's sales channels, gains or losses of
significant customers, timing of significant orders of the Company's products,
fluctuations in manufacturing yields, changes in product mix, wafer price
increases due to foreign currency fluctuations and general economic conditions.
The Company anticipates that a significant portion of its revenue will be
derived from a limited number of large orders, and the timing of receipt and
fulfillment of any such orders is expected to cause material fluctuations in the
Company's operating results, particularly on a quarterly basis.

         Due to the foregoing factors, quarterly revenue and operating results
are difficult to forecast. The Company's expense levels are based, in
significant part, on the Company's expectations as to future revenue and are
therefore relatively fixed in the short term. If revenue levels fall below
expectations, as has occurred during the years ended April 30, 1998 and 1997,
net income is likely to be disproportionately adversely affected because a
proportionately smaller amount of the Company's expenses varies with its
revenue. There can be no assurance that the Company will be able to achieve or
maintain profitability on a quarterly or annual basis in the future. Due to the
foregoing factors, the Company's operating results may fall below the
expectations of securities analysts and investors, which could have a material
adverse effect on the market price of the Company's Common Stock. Reductions in
revenue expectations can also require the Company to take additional reserves
against inventory valuations based upon the reduced likelihood that the Company
will be able to liquidate its inventories at profitable prices.

         Inventory. The cyclical nature of the semiconductor industry
periodically results in oversupply or shortages of wafer fabrication capacity
such as the Company has experienced from time to time. Since the Company must
order products and build inventory substantially in advance of product
shipments, there is a risk that the Company will forecast incorrectly and
produce excess or insufficient inventories of particular products because demand
for the Company's products is volatile and customers place orders with short
lead times. The ability of the Company's customers to reschedule or cancel
orders without significant penalty could adversely affect the Company's
liquidity, as the Company may be unable to adjust its purchases from its wafer
suppliers to match such customer changes and cancellations. There can be no
assurance that the Company's inventory will be reduced by the fulfillment of
customer orders or that in the future the Company will not produce excess
quantities of its products. To the extent the Company produces excess
inventories of particular products, the Company's operating results could be
adversely affected by charges that the Company could recognize due to
significant reductions in demand for its products, rapid declines in the market
value of inventory resulting in inventory writedowns or other related factors.



                                      -16-
<PAGE>   17

For example, during the last half of fiscal 1998, the Company recorded charges
of approximately $7.5 million attributable to reserves for lower of cost or
market adjustments and for excess and obsolete inventory adjustments. There can
be no assurance that the Company will not suffer similar reductions in values of
its inventories in the future or that the Company will be able to liquidate its
inventory at acceptable prices.

         Competition. The semiconductor industry is intensely competitive and
has been characterized by rapid price erosion, declining gross margins, rapid
technological change, product obsolescence and heightened international
competition in many markets. Average selling prices in the semiconductor
industry generally, and for the Company's products in particular, have decreased
significantly and rapidly over the life of each product. The Company expects
that average selling prices for its existing products will continue to decline
rapidly for the foreseeable future and that average selling prices for each new
product will decline significantly over the life of the product. Declines in
average selling prices for the Company's products, if not offset by reductions
in the cost of producing those products or by sales of new products with higher
gross margins, would decrease the Company's overall gross margins, could cause a
negative adjustment to the valuation of the Company's inventories and could
materially and adversely affect the Company's operating results.

         The Company competes with major domestic and international
semiconductor companies, many of which have substantially greater financial,
technical, sales, marketing, production, distribution and other resources than
the Company. The can be no assurance that the Company will be able to compete
successfully in the future. The Company's more mature products, such as Serial
and Parallel EEPROM devices, compete on the basis of product performance, price
and customer service. The Company believes it competes successfully with respect
to each of these competitive attributes; however price competition is
significant and expected to continue. Principal competitors with respect to the
Company's EEPROM products currently include SGS-Thomson, National Semiconductor,
Atmel and Xicor, as well as the Company's strategic manufacturing partner Oki,
all of which have substantially greater resources than the Company.

         The market for Flash memory products has been characterized by long
production cycles, irregular yields, competing technologies and, particularly
since the first quarter of fiscal 1997, intense price competition resulting in
major reductions in average selling prices and corresponding reductions in
margins. The Company's Flash memory products compete on the basis of product
performance, price and customer service. However, given the development of
higher density/lower cost products and the intense price competition prevalent
for these products, there can be no assurance that the Company will be able to
compete successfully in the future against its competitors on the bases of these
or other competitive factors.

         Dependence on Independent Foreign Manufacturers and Subcontractors;
Manufacturing Risks. The Company does not manufacture the semiconductor wafers
used for its products. The Company principally utilizes facilities of Oki
Electric Industry Co., Ltd. ("OKI") in Japan, and United Microelectronics
Corporation ("UMC") in Taiwan, to fabricate and test the Company's wafers and
subcontractors in Southeast Asia to assemble and test its integrated circuits.
To date, a majority of these wafers have been manufactured by OKI. The
manufacture of semiconductor products is highly complex and sensitive to a wide
variety of factors and, as is typical in the semiconductor industry, the
Company's outside wafer foundries from time to time have experienced lower than
anticipated production yields. While the Company believes it has an adequate
wafer supply to meet its currently anticipated needs, there can be no assurance
that the Company will continue to receive sufficient quantities of wafers at
favorable prices on a timely basis, if at all, or that the Company will be able
to attain higher levels of wafer supply as demand requires. Material disruptions
in the supply of wafers as a result of manufacturing yield or other
manufacturing problems are not uncommon in the semiconductor industry. The
Company may also be subject to production transition delays. There can be no
assurance that the Company will not experience such problems in the future.
Moreover, delays in the Company's payments to wafer suppliers resulting from the
Company's current cash constraints can often result in delays or reductions in
wafer deliveries and assembly and test services from the Company's suppliers.
Such delays and reductions can result in cancellations of customer orders
thereby adversely affecting the Company's ability to generate future revenues.
The loss of OKI as a supplier, any prolonged inability to obtain adequate yields
or deliveries from OKI or other subcontractor manufacturers, or any other
circumstance that would require the Company to seek and qualify alternative
sources of supply of products or services, could delay shipments, result in the
loss of customers and have a material adverse effect on the Company's business
and



                                      -17-
<PAGE>   18


operating results. Moreover, the inability to procure supplies and services from
these foreign subcontractor manufacturers on commercially reasonable terms as a
result of foreign currency exchange rate fluctuations may have a material
adverse effect on the Company's operating results. The Company also has concerns
about the financial viability of its primary test and assembly contractor.
Although the Company is exploring alternative contractors, there can be no
assurance that it will be able to obtain such alternative services or that the
Company will have adequate test and assembly facilities available. Failure to
have such services available would have a material adverse effect on the
Company's business, financial condition and results of operations. In addition,
the Company's business is subject to other risks generally associated with doing
business with foreign subcontractors including, but not limited to, foreign
government regulations, political and financial unrest which may cause
disruptions or delays in shipments to the Company's customers or access to the
Company's inventories.

         International Operations. For fiscal 1998, 1997 and 1996 international
sales accounted for approximately 64%, 63% and 60%, respectively, of the
Company's product sales. The Company expects that international sales will
continue to represent a significant portion of its product sales in the future.
The Company's international operations may be adversely affected by fluctuations
in exchange rates, imposition of government controls, political and financial
instability, trade restrictions, changes in regulatory requirements,
difficulties in staffing international operations and longer payment cycles. In
particular, recent adverse developments in the economic environment in the Far
East may have a material adverse effect on the Company's subcontractors. There
can be no assurance these or other factors related to international operations
will not have a material adverse affect on the Company's business, financial
condition and results of operations.

         New Product Development and Technological Change. The markets for the
Company's products are characterized by rapidly changing technology and product
obsolescence. The timely introduction of new products at competitive
price/performance levels is a key factor to the success of the Company's
business. In particular, the Company's future success will depend on its ability
to develop and implement new design and process technologies which enable the
Company to achieve higher product densities and thereby reduce product costs.
For example, most of the Company's products are currently designed and
manufactured using a 0.8 micron CMOS EEPROM process or a 0.5 micron Flash memory
process. There can be no assurance that the Company will be able to select and
develop new products and technologies and introduce them to the market in a
timely manner and with acceptable fabrication yields and production costs.
Furthermore, there can be no assurance that the Company's products will achieve
market acceptance. The failure of the Company to complete and introduce new
products at competitive price/performance levels could materially and adversely
affect the Company's business, financial condition and operating results. Delays
in developing new products, achieving volume production of new products,
successfully completing technology transitions with acceptable yields and
reliability or the lack of commercial acceptance of new products introduced by
the Company, could have a material adverse effect on the Company's business,
financial condition and results of operations.

         Flash Memory Market. A significant amount of the Company's net revenues
during 1998 were derived from sales of Flash memory products. The market for
Flash memory products has been characterized by intense price competition, long
production cycles, inconsistent yields, competing technologies, rapidly
declining average selling prices, declines in gross margins and intense overall
competition. The Company's fiscal 1997 and fiscal 1998 operating results were
adversely affected by intense price competition caused by increased supplies of
products and other adverse industry-wide conditions. Intel and other competitors
(which include Advanced Micro Devices, Atmel, Fujitsu, Hitachi, Micron,
Mitsubishi, SGS-Thomson, Sharp, Texas Instruments and Toshiba) are expected to
further increase Flash memory production. There can be no assurance that the
Company will be able to sustain the market acceptance for its Flash memory
products. The Company anticipates continued price and other competitive
pressures, which adversely affected fiscal 1997 and fiscal 1998 operating
results to adversely affect the Company's future operating results.

         Semiconductor Industry. The semiconductor industry is highly cyclical
and has been subject to significant economic downturns at various times,
characterized by diminished product demand, accelerated erosion of average
selling prices and gross margins, and production overcapacity. Accordingly, the
Company may experience substantial period to period fluctuations in future
operating results due to general semiconductor industry conditions, overall
economic conditions or other factors. For example, the Company experienced and
continues to experience accelerated erosion of average selling prices caused by
adverse industry-wide conditions in fiscal 1997 and fiscal 1998.

         Dependence on Proprietary Technology; Risk of Intellectual Property
Litigation. In the semiconductor industry companies place extensive reliance
upon their intellectual property and proprietary technology and it is



                                      -18-
<PAGE>   19


typical for companies to receive notices from time to time that allege
infringement of patents or other intellectual property rights of others. There
can be no assurance that the Company will not receive any such notification or
that proceedings alleging infringement of intellectual property rights will not
be commenced against the Company in the future. In such event, there can be no
assurances that the Company could obtain any required licenses of third party
intellectual property rights or could obtain such licenses on commercially
reasonable terms. Failure to obtain such a license in any event could require
the Company to cease production of its products until the Company develops a
non-infringing design or process. Moreover, the cost of litigation of any such
claim or damages resulting therefore could be substantial and could materially
and adversely affect the Company's business, financial condition and results of
operations.

         Dependence upon Key Personnel. The Company's ability to operate
successfully will depend, to a large extent, upon the continued service of
certain key employees, and the continued ability to attract and retain
additional highly qualified personnel. Competition for such personnel,
particularly for highly skilled design, process and test engineers, is intense
and there can be no assurance that the Company can retain such personnel or that
it can attract other highly qualified personnel. The loss of or failure to
attract and retain any such highly qualified personnel could have a material
adverse affect on the Company's business, financial condition and results of
operations.

         Customer Concentration. A relatively small number of customers have
accounted for a significant portion of the Company's net revenue in the past.
During fiscal years 1998, 1997 and 1996, the only customer which represented
more than ten percent of Catalyst's product revenue was Marubun Corporation, a
Japanese distributor (21%, 14% and 12%, respectively). In December 1997, Marubun
resigned as a distributor effective in or about March 1998. Loss of one or more
of the Company's current customers could materially and adversely affect the
Company's business, operating results and financial condition. In addition, the
Company has experienced and may continue to experience lower margins on sales to
significant customers as a result of volume pricing arrangements.

         Dependence on Manufacturer Representatives and Distributors. The
Company markets and distributes its products primarily through manufacturers'
representatives and independent distributors. The Company's distributors
typically offer competing products. The distribution channels have been
characterized by rapid change, including consolidations and financial
difficulties. The loss of one or more manufacturers' representatives or
distributors, or the decision by one or more distributors to reduce the number
of the Company's products offered by such distributors or to carry the product
lines of the Company's competitors, could have a material, adverse effect on the
Company's operating results.

         Year 2000 Compliance. The Company is currently working to assess the
potential impact of the Year 2000 on the processing of date-sensitive
information by the Company's computerized information systems. The Year 2000
problem is the result of computer programs being written using two digits
(rather than four) to define the applicable year. Any of the Company's programs
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000, which could result in miscalculations or system
failures. Costs of addressing potential problems are being considered but are
not expected to have a material adverse effect on the Company's business,
financial position, results of operations or cash flows in future periods.
However, if the Company or its vendors are unable to resolve such processing
issues in a timely manner, it could result in a material financial risk.
Accordingly, the Company plans to devote the necessary resources to resolve all
significant Year 2000 issues in a timely manner.

         Takeover Resistive Measures. The Company's Stockholder Rights Plan,
which provides stockholders with certain rights to acquire shares of Common
Stock in the event a third party acquires more than 15% of the Company's stock,
the Board's ability to issue "blank check" Preferred Stock without stockholder
approval and the Company's staggered terms for its directors, could have the
effect of delaying or preventing a change in control of the Company.

         Volatility of Stock Price. The Company's stock price has been and may
continue to be subject to significant volatility. Any shortfall in revenues or
earnings from levels expected or projected by securities analysts or others
could have an immediate and significant adverse effect on the trading price of
the Company's Common Stock in any given period. In addition, the stock market in
general has experienced extreme price and volume fluctuations particularly
affecting the market prices for many high technology companies and small
capitalization companies, and these fluctuations have often been unrelated to
the operating performance of the specific companies. These broad fluctuations
may adversely affect the market price for the Company's Common Stock.

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of
   Catalyst Semiconductor, Inc.


   In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of Catalyst
Semiconductor, Inc. and its subsidiary at April 30, 1998 and 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended April 30, 1998, in conformity with generally accepted
accounting principles. 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 of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

   The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has suffered recurring losses from operations
and has a net stockholders' deficit that raise substantial doubt about its
ability to continue as a going concern. Management's plans in regard to these
matters are also described in Note 1. The financial statements do not include
any adjustments that might result from the outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

   OPERATIONS

      Catalyst Semiconductor, Inc. ("Catalyst" or the "Company"), incorporated
October 8, 1985, designs, develops and markets nonvolatile memory semiconductor
products including Serial and Parallel EEPROMs and Flash memory. Revenues are
derived from sales of semiconductor products designed by the Company and
manufactured by other companies.

      The Company's business is highly cyclical and has been subject to
significant downturns at various times which have been characterized by reduced
product demand, production overcapacity, and significant erosion of average
selling prices. Throughout fiscal 1998, the market for certain FLASH and EEPROM
devices, which comprise the majority of Catalyst's business, experienced an
excess market supply relative to demand which resulted in a significant downward
trend in prices. The Company could continue to experience a downward trend in
product pricing which could further adversely affect the Company's operating
results.

      The Company's recent operating results have consumed substantial amounts
of cash. The reduction in cash has also placed restrictions on wafer purchases
which, during the fourth quarter of 1998, resulted in the cancellation of some
customer sales orders. In May 1998, the Company received net proceeds of $1.5
million from the sale of 1,500,000 shares of its Common Stock in a private
placement. Management believes, however, that it will require additional cash
from similar or related private placements or other sources of liquidity to meet
the Company's projected working capital and other cash requirements for fiscal
1999, and is currently pursuing other sources of liquidity.

   BASIS OF PRESENTATION


      Catalyst has a fiscal year that ends on the Sunday nearest April 30th. For
presentation purposes, the consolidated financial statements and notes refer to
the calendar month end. The consolidated financial statements include the
accounts of the Company and its wholly-owned subsidiary after elimination of all
significant intercompany balances and transactions.

      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 the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

   FOREIGN CURRENCY TRANSLATION

      The functional currency of the Company's Japanese subsidiary is the
Japanese yen. Accordingly, all assets and liabilities are translated at the
current exchange rate at the end of the period and revenues and expenses at
exchange rates in effect when incurred. Cumulative translation adjustments and
net gains and losses resulting from foreign exchange transactions were not
significant during any of the periods presented.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


   REVENUE RECOGNITION

      Revenue from product sales to original equipment manufacturers and from
sales to distributors who have no, or limited, product return rights and no
price protection rights, is recognized upon shipment net of allowances for
estimated returns. When distributors have rights to return products or price
protection rights, the Company defers revenue recognition until the time the
distributor sells the product to the end customer. Upon shipment by the Company,
amounts billed to distributors with rights to product returns or price
protection rights are included as accounts receivable, inventory is relieved,
the sale is deferred and the gross profit is reflected as a current liability
until the merchandise is sold to the end customer by the distributors. During
the fourth quarter of fiscal 1996, three distributors agreed to amend their
agreements and thereby waive price protection and certain return rights,
resulting in recognition of revenue previously deferred of approximately $2.4
million.

      Fees on development and license contracts are recognized using the
percentage of completion method, which generally coincides with the time when
the milestones defined in the contracts have been met and accepted by the
customer. Non-refundable deposits received in connection with development and
license contracts are recognized on a straight-line basis over the lives of the
contracts. Service fees derived from development and license agreements are
recognized as the services are performed. Royalties are recognized when the
licensee sells the related products. Development costs incurred relating to
license revenue and royalty income were not significant during any of the
periods presented.

   INVENTORIES

      Inventories are stated at the lower of cost, determined on the first-in,
first-out basis, or market.

      During fiscal 1996, the Company's operating results were favorably
impacted by the sale of Flash memory products for which the costs had been
written-down to an estimated net realizable value of zero at the end of fiscal
1994. If the costs had not been written-down in fiscal 1994, then cost of sales
would have been $2.2 million higher than the amounts reported for fiscal 1996.


PROPERTY AND EQUIPMENT

      Property and equipment are stated at cost and depreciated on a
straight-line basis over the estimated economic useful lives of the assets
(generally two to five years). Leasehold improvements are stated at cost and
amortized over their estimated useful lives or the remaining lease term,
whichever is shorter.

   FAIR VALUE OF FINANCIAL INSTRUMENTS

      For certain of the Company's financial instruments, including cash and
cash equivalents, short-term investments, accounts receivable, line of credit,
notes payable and accounts payable, the carrying amounts approximate fair value
due to their short maturities.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)



   CONCENTRATION OF CREDIT RISK

      Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash equivalents,
restricted cash and accounts receivable. Catalyst invests primarily in money
market accounts and certificates of deposit and places its investments with high
quality financial institutions. The restricted cash is held at a financial
institution as collateral for a letter of credit required by one of the
Company's foundries. The Company's accounts receivable are derived from sales to
original equipment manufacturers and distributors serving a variety of
industries located primarily in the United States, Europe and the Far East and
the Company performs ongoing credit evaluations of these customers. A majority
of the accounts payable balance is payable to a foreign foundry.

   DEPENDENCE ON WAFER SUPPLIERS

      The Company does not directly manufacture finished silicon wafers. The
Company's strategy has been to maintain relationships with wafer foundries.
However, there can be no assurance that the Company will be able to satisfy its
future wafer needs from current or alternative manufacturing sources. This could
result in possible loss of sales or reduced margins.

     During fiscal 1996, the Company signed an agreement with United
Microelectronics Corporation (UMC) of Taiwan. Under the terms of this agreement
the Company received a significant commitment of wafers from UMC in exchange for
rights to certain of the Company's designs. In addition, the Company received
net proceeds of $3.7 million from the sale of 650,000 shares of common stock to
UMC.


   STOCK-BASED COMPENSATION

      The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of Accounting Principles Board ("APB") No. 25,
"Accounting for Stock Issued to Employees," and complies with the disclosure
provisions of Statement of Financial Accounting Standards ("SFAS") No. 123,
"Accounting for Stock-Based Compensation." Under APB No. 25, compensation cost
is recognized based on the difference, if any, on the date of grant between the
fair value of the Company's stock and the amount an employee must pay to acquire
the stock.

   NET INCOME (LOSS) PER SHARE

      During the quarter ended January 31, 1998, the Company adopted Statement
of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128").
SFAS 128 requires presentation of both Basic EPS and Diluted EPS. Basic EPS is
computed by dividing net income available to common stockholders (numerator) by
the weighted average number of common shares outstanding (denominator) during
the period. Diluted EPS gives effect to all dilutive potential common shares
outstanding during a period. In computing Diluted EPS, the average price for the
period is used in determining the number of shares assumed to be purchased from
exercise of stock options, warrants and convertible preferred stock. Net income
(loss) per share presented for all prior periods has been restated to conform to
the provisions of SFAS 128.

     Options to purchase 2,637,000 shares of common stock at prices ranging from
$0.69 to $6.30 per share were outstanding during 1998 and 2,466,000 shares of
common stock at prices ranging from $1.08 to $6.30 per share were outstanding
during 1997, and were not included in the computation of diluted EPS because the
inclusion of such options and shares would have been antidilutive.

   NEW ACCOUNTING STANDARDS

      In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement No. 130, "Reporting Comprehensive Income" ("FAS 130"). FAS 130
establishes standards for reporting comprehensive income and its components in a
financial statement that is displayed with the same prominence as other
financial statements. Comprehensive income as defined includes all changes in
equity (net assets) during a period from non-owner sources. Examples of items to
be included in comprehensive income, which are excluded from net income, include
foreign currency translation adjustments and unrealized gain/loss on
available-for-sale securities. The disclosure prescribed by FAS 130 must be made
beginning with the first quarter of fiscal 1999.

      In June 1997, the FASB issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("FAS 131"). This statement
establishes standards for the way companies report information about operating
segments in annual financial statements. It also establishes standards for
related disclosures about products and services, geographic areas, and major
customers. The Company has not yet determined the impact, if any, of adopting
this new standard. The disclosures prescribed by FAS 131 are effective for the
Company's annual consolidated financial statements for the year ending April 30,
1999.

NOTE 3 -LINE OF CREDIT:

      Under the terms of a bank revolving line of credit in place at April 30,
1998, the Company could borrow the lesser of $13.5 million or an amount
determined by a formula applied to eligible accounts receivable, local inventory
and backlog from certain foreign customers. The line of credit bears interest at
a variable rate equal to the bank's prime lending rate plus 2.25% (13.75% at
April 30, 1998). As of April 30, 1998, $5.75 million of the amount borrowable
had been pledged as security for bank letters of credit. The revolving line of
credit expires on June 19, 1999. Amounts borrowed on the line of credit are
secured by accounts receivable and inventory and subject to compliance with loan
covenants. At April 30, 1998 and 1997, the Company had borrowings of $3.2
million outstanding and $3.4 million under the line of credit agreements. At
April 30, 1998, the Company was in default under various provisions of the loan
agreement entitling the Bank to terminate the loan agreement and declare the
loans immediately due and payable. As a result of noncompliance with the terms
of the loan, the Company cannot currently borrow any additional funds under the
line.

      On February 15, 1997, a vendor loaned $1.2 million to the Company in
settlement of billings for assembly and test services totaling the same. The
loan, which bears interest at 18%, was due and payable on May 15, 1998. The loan
is classified under the current portion of long-term debt at April 30, 1998.

NOTE 4 - LEASES:

      At April 30, 1998 and 1997, the net book value of assets recorded as
property and equipment under capital leases aggregated $0.7 million and $0.5
million, which is net of accumulated amortization of $1.5 million and $1.2
million, respectively. The amortization of assets recorded under capital leases
is included with depreciation and amortization expense.

      The Company leases its office facilities under operating leases. Total
rent expense under these leases was $416,000, $498,000 and $412,000 for fiscal
1998, 1997 and 1996, respectively.

     Tax loss carryforwards at April 30, 1998 are approximately $37.6 million
for federal purposes. These carryforwards begin to expire in fiscal 2007. The
research and development credits begin to expire in fiscal 2001. Availability of
the net operating loss and credit carryforwards may potentially be reduced in
the event of certain substantial changes in equity ownership.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     No provision is made for income taxes relating to potential future
distributions of accumulated earnings from the Company's foreign subsidiary,
which at April 30, 1998 were not significant, since it is the Company's
intention to reinvest substantially all of the undistributed earnings in its
foreign operations.

NOTE 6 - STOCK PLANS:

   STOCK OPTION PLANS

     In October 1989, the Company adopted a stock option plan (the "Option
Plan") for incentive stock options and non-statutory stock options. A total of
3.3 million shares of Common Stock have been reserved for issuance under the
Option Plan. Options granted under the Option Plan are for periods not to exceed
ten years. Incentive stock option and non-statutory stock option grants under
the Option Plan must generally be at prices equal to 100% of the fair market
value of the stock at the date of grant. Options generally vest over four year
periods.

     During 1993, the Company adopted a Director Stock Option Plan (the
"Director Plan") which provides for the grant of nonstatutory stock options to
nonemployee directors. A total of 220,000 shares of Common Stock have been
reserved for issuance under the Director Plan. Options granted under the
Director Plan are for periods not to exceed five years. Option grants under the
Director Plan must be at prices equal to 100% of the fair market value of the
stock at the date of grant. Options vest over a period of three years. As of
April 30, 1998 a total of 171,000 options at exercise prices ranging from $0.90
to $6.00 per share, have been granted under the Director Plan, 52,000 of which
were exercisable.

     During fiscal 1993, the Company issued to certain employees stock options
at prices which gave rise to deferred compensation expense. In connection with
the issuance of these stock options, the Company recorded $316,000 as deferred
compensation and recognized $46,000 and $81,000 as compensation expense for
fiscal 1997 and 1996, respectively. The remaining $189,000 was recognized in
years prior to fiscal 1996.

     In January 1998, the Board of Directors offered employee holders of options
the opportunity to cancel such options and receive an equal amount of options
with an exercise price per share equal to the then current fair market value. As
a result, options to purchase approximately 1.8 million shares were canceled and
an equal number were granted at an exercise price of $1.06.

   OTHER STOCK PLANS

     The Board of Directors and Stockholders approved the Company's Employee
Stock Purchase Plan (the "Purchase Plan") in March 1993. A total of 250,000
shares of Common Stock have been reserved for issuance under the Purchase Plan.
Sales made through this plan will be at the lower of 85% of the market price at
the date of purchase or on the first day of each six-month offering period. As
of April 30, 1998, a total of 228,000 shares have been issued under the Purchase
Plan.


   PRO FORMA STOCK COMPENSATION DISCLOSURE

     The fair value of each option granted is estimated on the date of grant
using the Black-Scholes option-valuation model with the following
weighted-average assumptions used for options granted in 1998, 1997 and 1996,
respectively: dividend yield of 0 percent for all years, expected volatility of
79, 80 and 80 percent, risk free interest rates of 5.50, 6.12 and 5.86, and
expected lives of 3 years for non-officer/director employees and 4 years for
officers and directors for all years.

     The fair value of each share granted under the Purchase Plan is estimated
on the date of grant using the Black-Scholes option-valuation model with the
following weighted-average assumptions used for shares granted in 1998, 1997 and
1996, respectively: dividend yield of 0 percent for all years, expected
volatility of 79, 86 and 80 percent, risk free interest rates of 5.36, 5.32 and
5.43, and expected lives of 0.5 years for non-officer/director employees and 
officers and directors for all years.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


     The Company has elected to continue to apply APB Opinion 25 in accounting
for its stock option plans. Accordingly, no compensation cost has been
recognized for its stock option plans and its Purchase Plan. Had compensation
cost for the Company's stock-based compensation plans been determined based on
the fair value at the grant dates for awards under those plans consistent with
the method of SFAS 123, the Company's net income (loss) and net income (loss)
per share would have been reduced to the pro forma amounts below (in thousands,
except per share amounts):

</TABLE>

     The above pro forma amounts include compensation expense based on the fair
value of options vesting during the years ended April 30, 1998, 1997 and 1996
and exclude the effects of options granted prior to May 1, 1995. Accordingly,
the above pro forma net income (loss) and net income (loss) per share are not
representative of the effects of computing stock option compensation expense
using the fair value method for future periods.

      The Company sells product to its Japanese distributor, which is also a
stockholder. Revenue from this stockholder represented $7.2 million, $6.5
million and $7.3 million or approximately 21%, 14% and 12% of product sales for
the years ended April 30, 1998, 1997 and 1996, respectively. No other customer
accounted for 10% or more of product sales.

      Sales and purchase transactions are denominated in U.S. dollars, except
for certain sales and purchases which were denominated in Japanese yen and which
were insignificant for the years ended April 30, 1998, 1997 and 1996. Certain
test equipment, with a net book value of approximately $0 million, $0.9 million
and $0.9 million at April 30, 1998, 1997 and 1996, respectively, is located at a
foreign subcontractor's facilities. Except for such equipment, the Company has
no significant assets located outside of the U.S.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     In the normal course of business, the Company receives notification of
threats of legal action in relation to claims of patent infringement by the
Company. Although no assurances can be given to the results of these claims,
management does not believe that any such results will have a material adverse
impact on the Company's financial condition or results of operations.

     The Company is also negotiating with several creditors who have threatened
or filed legal action for the non-payment of amounts owed to them by the
Company. Management believes that the resolution of these claims will be
forthcoming and the resolution will not have a material adverse impact on the
Company's financial condition or results of operations.

NOTE 9 - SUBSEQUENT EVENT:

     In May 1998, a private investor purchased 1,500,000 shares of the Company's
common stock in a private placement for $1.00 per share. The offer and sale of
the securities was exempt from registration under the Securities Act of 1933,
as amended, pursuant to Section 4(2) of such Act. In connection with such
issuance the investor agreed to various standstill and voting provisions
including not acquiring additional shares of Company Stock or taking actions to
control the Company. The Company also has certain repurchase rights with
respect to the shares sold over the twelve months from the date of issuance.

                           LOAN AND SECURITY AGREEMENT


BORROWER:         CATALYST SEMICONDUCTOR, INC.,
                  A DELAWARE CORPORATION

ADDRESS:          1250 BORREGAS AVENUE
                  SUNNYVALE, CALIFORNIA 94089

DATE:             JUNE 19, 1997

THIS LOAN AND SECURITY AGREEMENT ("Loan Agreement"), dated the above date, is
entered into at Los Angeles, California, between COAST BUSINESS CREDIT, a
division of Southern Pacific Thrift & Loan Association ("Coast"), a California
corporation, with offices at 12121 Wilshire Boulevard, Suite 1111, Los Angeles,
California 90025, and the borrower named above ("Borrower"), whose chief

hereafter request that Coast advance funds or otherwise extend credit to or for
the benefit of Borrower ("Loan(s)") in accordance with the terms and provisions

including, but not limited to, any one or more of the following described
security agreements now or hereafter entered into between Borrower and Coast:
(a) Accounts Collateral Security Agreement; (b) Inventory Collateral Security
Agreement; (c) Intellectual Property Collateral Security Agreement; and (d) any
promissory notes or guaranties. The amount and terms of payment of any Loans by
Coast to Borrower shall be determined in accordance with the terms and
provisions of this Loan Agreement and of any executed Collateral Agreements.
Notwithstanding anything herein or in any Collateral Agreement to the contrary,
in no event shall the Borrower permit the total balance of all Loans and all
other Obligations (including without limitation the Obligations under and as
defined in the CEFO Agreement, as defined below) outstanding at any one time to
exceed $13,500,000 ("Maximum Dollar Amount"); and, if for any reason they do,
Borrower shall immediately pay the amount of such excess to Coast in immediately
available funds.

         1.2 INTEREST. Unless specifically provided to the contrary in any
Collateral Agreement, all Loans shall bear interest at a rate equal to the
"Prime Rate" (as hereinafter defined), plus 2.25% per annum, calculated on the
basis of a 360-day year for the actual number of days elapsed provided, however,
all Loans shall bear interest at a rate equal to the Prime Rate plus 1.75% per
annum upon receipt of evidence acceptable to Coast in its sole and absolute



<PAGE>   2

and thereafter maintained a Tangible Net Worth (as that term is defined herein)
of no less than $17,000,000. 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 that month shall be based on the highest "Prime Rate" in effect
during said month, but in no event shall the rate of interest charged on any
Loans in any month be less than 8% per annum. "Prime Rate" is defined as the
actual "Reference Rate" or the substitute therefor of the Bank of America NT &
SA ("B of A") whether or not that rate is the lowest interest rate charged by B
of A. 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. Regardless of the amount of Obligations that may
be outstanding from time to time, Borrower shall pay Coast minimum monthly
interest during the of this Agreement with respect to the Loans the amount of
Fifty Thousand Dollars ($50,000) per quarter (prorated for any partial quarter
at the beginning of the term of this Agreement).

         1.3 FEES. Borrower shall pay to Coast a loan origination fee in the
amount of $101,250 concurrently herewith, and an annual loan fee of n/a on each
anniversary of the date hereof during the term of this Loan Agreement. Borrower
shall pay to Coast a facility fee of Two Thousand Eight Hundred Dollars ($2,800)
per quarter (prorated for any partial quarter at the beginning of the term of
this Agreement). Borrower shall pay to Coast a letter of credit fee of 0.45% per
annum of the aggregate face amount of all outstanding letters of credit plus
Coast's expenses, payable at funding and thereafter payable each year in advance
(prorated for any partial year at the beginning of the term of this Agreement).
Said fees are in addition to all other sums payable to Coast, are not refundable
for any reason, and shall bear interest from the date due to the date paid at
the highest interest rate applicable to any of the Obligations.

         1.4 LETTERS OF CREDIT. At the request of Borrower, Coast may, in its
sole discretion, arrange for the issuance of letters of credit for the account
of Borrower (collectively, "Letters of Credit"), by issuing guarantees to the
issuer of the letter of credit or by other means. All Letters of Credit shall be
in form and substance satisfactory to Coast in its sole discretion. The
aggregate face amount of all outstanding Letters of Credit from time to time
shall not exceed $7,500,000 (the "Letter of Credit Sublimit"), and shall be
reserved against Loans which would otherwise be available hereunder. Borrower
shall pay all bank charges for the issuance of Letters of Credit. Any payment by
Coast under or in connection with a Letter of Credit shall constitute a Loan
hereunder on the date such payment is made. Each Letter of Credit shall have an
expiry date no later than thirty (30) days prior to the initial renewal date set
forth in Section 8 and thereafter each subsequent renewal date. Borrower hereby
agrees to indemnify, save, and hold Coast harmless from any loss, cost, expense,
or liability, including payments made by Coast, expenses, and reasonable
attorneys' fees incurred by Coast arising out of or in connection with any
Letters of Credit. Borrower agrees to be bound by the regulations and
interpretations of the issuer of any Letters of Credit guarantied by Coast and
opened for Borrower's account or by Coast's interpretations of any Letter of
Credit issued by Coast for Borrower's account, and Borrower understands and
agrees that Coast shall not be liable for any error, negligence, or mistake,
whether of omission or commission, in following Borrower's instructions or those
contained in the Letters of Credit or any modifications, amendments, or
supplements thereto. 



                                      -2-
<PAGE>   3

Borrower understands that Letters of Credit may require Coast to indemnify the
issuing bank for certain costs or liabilities arising out of claims by Borrower
against such issuing bank. Borrower hereby agrees to indemnify and hold Coast
harmless with respect to any loss, cost, expense, or liability incurred by Coast
under any Letter of Credit as a result of Coast's indemnification of any such
issuing bank. The provisions of this Loan Agreement, as it pertains to Letters
of Credit, and any other present or future documents or agreements between
Borrower and Coast relating to Letters of Credit are cumulative.

other agreement is a deed of trust or other security instrument having real
property or rents from real property as its subject matter and expressly
provides to the contrary.

3.       REPRESENTATIONS, WARRANTIES AND COVENANTS OF BORROWER

         To induce Coast to enter into this Loan Agreement and now and hereafter
to enter into any Collateral Agreement, Borrower represents and warrants that
each of the following representations and warranties now is and hereafter will
continue to be true and correct in all respects and Borrower has and will timely
perform each of the following covenants:

                  3.1 CORPORATE EXISTENCE AND POWER. Borrower, if a corporation,
is and will continue to be, duly authorized, 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 the nature of the business transacted by it, or the
ownership or leasing of its property, makes such qualification or licensing
necessary and where the failure to be so qualified would have a material adverse
effect on the Borrower, and Borrower has and will continue to have all requisite
power and authority to carry on its business as it is now, or may hereafter be,
conducted.
                  3.2 AUTHORITY. Borrower is, and will continue to be,
authorized to enter into, to grant security interests in its property pursuant
to, and to perform its obligations under, this Loan Agreement, any Collateral
Agreement and all other instruments and transactions 



                                      -5-
<PAGE>   6

contemplated herein. The execution, delivery and performance by Borrower of this
Loan Agreement, any Collateral Agreement and all other instruments and
transactions contemplated herein have been validly authorized, are enforceable
against the Borrower in accordance with their terms, and do not violate any law
or any provision of Borrower's Articles of Incorporation, By-Laws and any
Shareholder Agreements nor do they violate any material provision of, nor will
they result in acceleration under, any material agreement, indenture, note or
instrument which is binding upon Borrower, or any of its property.

                  3.3 Name; Trade Names and Styles. Borrower has set forth above
its correct name. Listed on the Schedule hereto are all prior names of Borrower
and each fictitious name, trade name and trade style by which Borrower has been,
or is now, known. Borrower shall provide Coast with fifteen (15) days' advance
written notice prior to doing business under any other name, fictitious name,
trade name or trade style. Borrower has complied, and will hereafter comply,
with all laws relating to the conduct of business under, the ownership of
property in, and the renewal or continuation of the right to use, a corporate,
fictitious or trade name or trade style.

                  3.4 PLACE OF BUSINESS; LOCATION OF COLLATERAL. Borrower's sole
place of business; or, if Borrower has more than one place of business,
Borrower's chief executive office; or, if Borrower is an individual and does not
have a separate place of business, Borrower's residence is, and will continue to
be, located at Borrower's Address and all of Borrower's books and records,
including, but not limited to, the books and records relating to Borrower's
Accounts, are and will be maintained at Borrower's Address unless and until
Coast shall otherwise consent in writing. In addition to Borrower's Address,
Borrower has places of business and Collateral is located only at the locations
shown on the Schedule hereto. Borrower will provide Coast with at least fifteen
(15) days advance written notice if Borrower moves any of the Collateral to any
new location not previously reported to Coast, or obtains any additional sites
for the conduct of Borrower's business or the location of any Collateral.

                  3.5 TITLE TO COLLATERAL; LIENS. Borrower is now, and will at
all times hereafter be, the lawful and sole owner of all the Collateral. With
the exception of the security interest granted Coast, the Collateral now is and
will remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims ("Liens"), other than Permitted Liens. As used
herein, "Permitted Liens" means (i) any Liens existing as of the date hereof and
disclosed in Schedule A hereto; (ii) Liens for taxes, fees, assessments or other
governmental charges or levies, either not delinquent or being contested in good
faith by appropriate proceedings, provided the same have no priority over any of
Coast's security interests; (iii) Liens of materialmen, mechanics, warehousemen,
carriers, or employees or other like Liens arising in the ordinary course of
business and securing obligations either not delinquent more than 45 days or
being contested in good faith by appropriate proceedings; (iv) any judgment,
attachment or similar lien, unless the judgment it secures is not fully covered
by insurance and has not been discharged or execution thereof effectively stayed
and bonded against pending appeal within 30 days of the entry thereof provided
that, if the judgment is not fully covered by insurance or execution thereof has
not been so stayed and bonded, Coast shall not be required to make any Loans or
otherwise extend credit to or for the benefit of Borrower; (v) Liens (i) upon or
in any equipment acquired or to be acquired, held or leased by the Borrower to
secure the purchase 



                                      -6-
<PAGE>   7

price of such equipment or indebtedness incurred solely for the purpose of
financing the acquisition of such equipment or (ii) existing on such equipment
at the time of its acquisition or lease, provided that the Lien is confined
solely to the equipment so acquired and improvements thereon; (vi) Leases or
subleases and licenses or sublicenses granted to others not interfering in any
material respect with the business of Borrower; (vii) Encumbrances securing
reimbursement obligations of Borrower with respect to commercial letters of
credit, provided that such encumbrances shall attach only to documents or other
property relating to such letters of credit and products and proceeds thereof
that are not Collateral under this Agreement or any of the Collateral Agreements
subsequent to the delivery of such property to Borrower; (viii) Liens incurred
in connection with the extension, renewal or refinancing of the indebtedness
secured by Liens of the type described in clauses (i) and (v) above, provided
that any extension, renewal or replacement Lien shall be limited to the property
encumbered by the existing Lien and the principal amount of the indebtedness
being extended, renewed or refinanced does not increase; (ix) Liens securing
debt junior in perfection and priority to the lien of Coast which are expressly
subordinated to Coast on terms satisfactory to Coast (including a provision
stating that the secured party shall not take action to enforce its lien so long
as any of the Obligations remain outstanding); (x) Liens in favor of customs and
revenue authorities which secure payment of customs duties in connection with
the importation of goods; (xi) Liens which constitute rights of set-off of a
customary nature or bankers' liens on amounts on deposit, whether arising by
contract or by operation of law, in connection with arrangements entered into
with depository institutions in the ordinary course of business; and (xii) other
Liens in existence on the date hereof and listed on Schedule A hereto. Without
limiting any of Coast's other rights and remedies, if Borrower grants any third
party a lien or encumbrance on or security interest (other than a Permitted
Lien) in any of the Collateral, Coast, in its sole discretion, shall have the
right to treat such action as a notice of termination by Borrower to Coast under
Paragraph 8(d) hereof, as of any date subsequent to such grant selected by
Coast, in its sole discretion, and to charge Borrower the termination fee
therein provide Coast now has, and will have, a perfected and enforceable first
priority security interest in all of the Collateral (other than Collateral
subject to a Permitted Lien) to the extent that such security interest can be
perfected by the filing of financing statements, and Borrower will at all times
defend Coast and the Collateral against all claims of others. 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 except for leases of
sales offices at which not more than $200,000 in Collateral is located. 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, whatever waivers and subordinations that Coast specifies, 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.

                  3.6 MAINTENANCE OF COLLATERAL. Borrower has maintained and
will maintain the Collateral and all of its assets in good working condition, at
Borrower's expense. Borrower 



                                      -7-
<PAGE>   8

will not use the Collateral or any of its other properties for any unlawful
purpose and will not secrete or abandon the Collateral except for the
abandonment of worn-out or obsolete equipment or inventory in the ordinary
course of business. Borrower will immediately advise Coast in writing of any
material loss or depreciation of the Collateral.

                  3.7 BOOKS AND RECORDS. Borrower has maintained and will
maintain at Borrower's Address books and records which are complete and accurate
in all material respects and which comprise an accounting system in accordance
with generally accepted accounting principles. Borrower has not and will not in
the future enter into any agreement with any accounting firm, service bureau or
third party to prepare or store Borrower's books and records at any location
other than Borrower's Address, without first obtaining Coast's written consent,
which may be conditioned upon such accounting firm, service bureau or other
third party agreeing to give Coast the same rights with respect to access to
books and records and related rights as Coast has under Paragraph 4.3 of this
Loan Agreement.

                  3.8 FINANCIAL CONDITION AND STATEMENTS. All financial
statements now or hereafter delivered to Coast have been, and will be, prepared
in conformity with generally accepted accounting principles and now and
hereafter will fairly reflect the financial condition of Borrower, at the times
and for the periods therein stated. Since the last date covered by any such
statement, there has been no material adverse change in the financial condition,
operations or any other status of the Borrower. Borrower is now and will
continue to be solvent in both the "equity" and "bankruptcy" sense. Borrower
will deliver to Coast a copy of all reports and financial statements in
accordance with Schedule 4.2.

                  3.9 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower
has timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state or local law. Borrower has timely paid, and will timely
pay, all foreign, federal, state and local taxes, assessments, deposits and
contributions now or hereafter owed by Borrower. Borrower may defer payment of
any contested taxes provided that Borrower (i) in good faith contests Borrower's
obligation to pay such taxes by appropriate proceedings promptly and diligently
instituted and conducted, (ii) notifies Coast in writing of the commencement of
and any material development in such proceedings, and (iii) posts bonds or takes
any other steps required to keep such contested taxes from becoming a lien
(other than Permitted Liens) against or charge upon any of the Collateral or
other properties of Borrower. 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. 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, without limitation, any liability to the Pension Benefit Guaranty
Corporation or its successors or any other governmental agency. When requested,
Borrower will furnish Coast with proof satisfactory to Coast of Borrower's
making the payment or deposit of all such taxes and contributions, such proof to
be delivered 



                                      -8-
<PAGE>   9

within five (5) days after the due date established by law for each such payment
or deposit. If Borrower fails or is unable to pay or deposit such taxes or
contributions, Coast may, but is not obligated to, pay the same and treat all
such advances as additional Obligations of Borrower. Such advances shall bear
interest at the highest interest rate applicable to any of the Obligations.

                  3.10 COMPLIANCE WITH LAW. Unless noncompliance would not
materially adversely affect (i) Borrower's financial condition as reflected in
its financial statements previously delivered to Coast; (ii) Borrower's
operations; or (iii) Borrower's business, Borrower has complied, and will
comply, with all provisions of all 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, conduct and licensing of
Borrower's business and employment of Borrower's personnel.

         3.11 LITIGATION. There is no claim, suit, litigation, proceeding or
investigation pending or threatened by or against or affecting Borrower in any
court or before any regulatory commission, beard or other governmental agency
(or any basis therefor known to Borrower) which is reasonably likely to result,
either separately or in the aggregate, in any material adverse change in the
business or condition of Borrower, or in any impairment in the ability of
Borrower to carry on its business in substantially the same manner as it is now
being conducted. Borrower will immediately inform Coast in writing of any claim,
proceeding, litigation or investigation hereafter threatened or instituted by or
against Borrower involving any single claim of $50,000 or more, or involving
$100,000 or more in the aggregate.

         3.12 USE OF PROCEEDS. 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." All proceeds of all Loans
shall be used solely for lawful business purposes.

         3.13 CONTINUING EFFECT. All representations, warranties and covenants
of Borrower contained in this Loan Agreement and any Collateral Agreement and
any other agreement with Coast shall be true and correct at the time of the
effective date of each such agreement and shall be deemed continuing and shall
remain true, correct and in full force and effect until payment and satisfaction
in full of all of the Obligations, and Borrower acknowledges that Coast is and
will be expressly relying on such representations, warranties and covenants in
making Loans to Borrower.

         4.       ADDITIONAL DUTIES OF BORROWER.

                  4.1 INSURANCE. Borrower shall, at all times, at Borrower's
expense, insure all of the Collateral and carry such other business insurance
with insurers reasonably acceptable to Coast, in such form and amounts as Coast
may reasonably require. All such insurance policies shall name Coast as an
additional loss payee, shall provide that proceeds payable thereunder be payable
directly to Coast unless written authority to the contrary is obtained, and
shall also provide that no act or default of Borrower or any other person shall
affect the right of Coast to recover thereunder and shall contain a lenders loss
payee endorsement in form acceptable to 



                                      -9-
<PAGE>   10

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 and absolute discretion provided that if no Event of Default has occurred
and is continuing, and the proceeds are less than $250,000 Coast shall release
the same to the Borrower for the repair or replacement of the property affected.
If Borrower fails to provide or pay for any such insurance, Coast may, but is
not obligated to, procure the same at Borrower's expense. Borrower agrees to
deliver to Coast, promptly as rendered, copies of all material reports made to
all insurance companies.

                  4.2 REPORTS. At its expense, Borrower shall report, in form
satisfactory to Coast, such information as Coast may from time to time
reasonably specify regarding Borrower or the Collateral including, without
limitation, the written reports set forth in Schedule 4.2 hereto; such reports
shall be rendered with such frequency as Coast may reasonably specify. All
reports furnished Coast shall be complete and accurate in all material respects.

                  4.3 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At any time (but
in no event less than quarterly) Coast, or its agents, shall have immediate
access to the Collateral and any other property of Borrower, wherever located
provided that if no Event of Default has occurred and is continuing, such access
shall be on one business days notice and during normal business hours. Coast
shall have the right to audit and copy Borrower's books and records and accounts
including accountants' reports wherever located ("hereinafter collectively the
"Records"). Such audits shall be at Borrower's expense and the charge for the
audits shall be $750 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. Borrower hereby irrevocably authorizes and directs any of the
officers, agents, accountants and attorneys having possession or control of any
of the Records (including computer records) to physically deliver or make same
available to Coast upon Coast's request. Coast shall have the right to
possession of, or to move to the premises of Coast or any agent of Coast, for so
long as Coast may desire, all or any part of the Records. All of the rights of
Coast under this Section 4.3 shall be subject to the provisions of Section 14.11
of this Agreement.

                  4.4 PROHIBITED TRANSACTIONS. Borrower shall not without
Coast's prior written consent: merge, consolidate, dissolve, acquire any other
corporation; enter into any transaction not in its usual course of business;
guarantee or otherwise become in any way liable with respect to the obligations
of another party or entity (except by endorsements of instruments or items of
payment for deposit to the general account of Borrower or which are transmitted
or turned over to Coast on account of the Obligations); pay or declare any
dividends upon Borrower's stock except that that Borrower may repurchase or
redeem shares of its capital stock pursuant to employee option plans for an
aggregate purchase price not to exceed $100,000 per fiscal year, on a
non~umulative basis; redeem, retire, purchase or otherwise acquire, directly or
indirectly, any of Borrower's stock; make any change in Borrower's name,
identity, corporate or capital structure (except that Borrower may issue common
stock upon exercise of stock options, 



                                      -10-
<PAGE>   11

sell shares of its capital stock for cash, and issue convertible debentures
subordinate in all respects to the Obligations pursuant to subordination
provisions acceptable to Coast in its discretion); sell or transfer any
Collateral, except for the sale of finished inventory in the ordinary course of
Borrower's business and except that, provided no Event of Default has occurred
and is continuing, Borrower may sell excess equipment in the ordinary course of
business in good faith arm's length transactions, and retain the proceeds
thereof for use in its business; lend or distribute any of Borrower's property
or assets, or incur any debts, outside of the ordinary course of Borrower's
business.

                  4.5 NOTIFICATION OF CHANGES. Borrower will promptly notify
Coast in writing of any change of its officers, directors, the death of any
partner or joint venturer, any purchase in excess of $50,000 out of the regular
course of Borrower's business without Coast's consent and any adverse or
material change in the business or financial affairs of Borrower.

                  4.6 CHARGES. Borrower shall pay all charges assessed by Coast,
in accordance with Coast's schedule of charges in effect from time to time, and
such charges shall be part of the Obligations and shall be payable on demand.

                  4.7 LITIGATION COOPERATION. Should any suit or proceeding be
instituted by or against Coast with respect to any Collateral or for the
collection or enforcement of any Account, or in any manner relating to Borrower,
Borrower shall, without expense to Coast, and wherever and whenever designated
by Coast, make available Borrower and its officers, employees and agents and
Borrower's Records to the extent that Coast may deem necessary in order to
prosecute or defend any such suit or proceeding.

                  4.8 REMITTANCE OF PROCEEDS. All proceeds arising from the
disposition of the Collateral shall be delivered, in kind, by Borrower to Coast
in the original form in which received by Borrower not later than the following
business day alter receipt by Borrower except (I) wire transfer remittances
received by Borrower shall be transmitted to Coast in total the day following
posting to Borrower's bank account. Borrower agrees that it will not commingle
proceeds of Collateral with any of Borrower's other fluids or property, but will
hold such proceeds separate and apart from such other fluids and property and in
an express trust for Coast. Coast may from time to time verify directly with the
respective account debtors the validity, amount and any other matters relating
to the Accounts 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 EXECUTE ADDITIONAL DOCUMENTATION. Borrower agrees, at its
expense, on demand by Coast, to execute all documents in form satisfactory to
Coast, as Coast, in its sole discretion, may deem reasonably necessary or useful
in order to perfect and maintain Coast's perfected first-priority or any other
security interest in the Collateral, and in order to fully consummate all of the
transactions contemplated under this Loan Agreement and under any Collateral
Agreement.

                  4.10 TANGIBLE NET WORTH. Borrower shall maintain, at all time
at which any Obligations remain outstanding, a minimum Tangible Net Worth of
Eleven Million Dollars ($11,000,000) where "Tangible Net Worth" means
consolidated stockholders' equity, less, 



                                      -11-
<PAGE>   12

goodwill, patents, trademarks, copyrights, franchises, formulas, leasehold
interests, leasehold improvements, non-compete agreements, engineering plans,
deferred tax benefits and organization costs.

5.       APPLICATION OF PAYMENTS.

         All forms of payments delivered to Coast on account of the Obligations
constitute conditional payment only until such items are actually paid in cash
to Coast; solely for the purpose of computing interest earned by Coast, credit
therefor and for bank wire transfers shall be given as of the first fifth
business day alter receipt by Coast as to uncollected ands and zero days alter
receipt of collected (goods) funds in order to allow for clearance, bookkeeping
and computer entries. All payments made by Borrower may be applied, and in
Coast's sole discretion reversed and re-applied, in whole or in part to any of
the Obligations, in such order and manner as Coast shall determine in its sole
discretion.

6.       EVENTS OF DEFAULT AND REMEDIES.

         6.1 EVENTS OF DEFAULT. If any of the following events shall occur, such
an occurrence shall constitute an "Event of Default" and Borrower shall provide
Coast with immediate written notice thereof: (a) Any warranty, representation,
statement, report or certificate made or delivered to Coast by Borrower or any
of Borrower's officers, employees or agents now or hereafter shall be incorrect
false, untrue or misleading in any material respect; or (b) Borrower shall fail
to repay when due part or all of any Loan or to pay any interest thereon when
due; or (c) Borrower shall fail to perform when due any term or condition
contained in this Loan Agreement or in any Collateral Agreement, or any other
agreement between Coast and Borrower; or (d) Borrower shall fail to pay or
perform any other Obligation when due; or (e) Any loss, theft, or substantial
damage to, or destruction of; any or all of the Collateral (unless within five

itself insecure because of (i) the occurrence of an event prior to the effective

                  6.2 REMEDIES. Upon the occurrence of any Event of Default, and
at any time thereafter, Coast, at its option, and without notice or demand of
any kind (all of which are hereby expressly waived by Borrower) (except that,
prior to or concurrently with the taking of the first of any of the following
actions, Coast shall give Borrower one general written notice stating that Coast
is "proceeding to exercise its rights and remedies" or words to that effect),
may do any one or more of the following: (a) Cease advancing money or extending
credit to or for the benefit of Borrower under this Loan Agreement, any
Collateral Agreement, and 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 the
Borrower's premises without hindrance to search for, take possession of, keep,

custodian to remain thereon in exclusive control thereof without charge for so
long as Coast deems necessary in order to complete the enforcement of its rights
under this Loan 



                                      -13-
<PAGE>   14

Agreement or any Collateral Agreement, or any other agreement; provided,
however, that should Coast seek to take possession of any or all 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 a place
or places to be designated by Coast which are reasonably convenient to Coast and
Borrower, and to remove the Collateral to such locations as Coast may deem

portion of the 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. Without limiting any security interest granted Coast in other
provisions of this Loan Agreement or in any Collateral Agreement or other
agreement, for the purpose of completing manufacturing, processing or repair of
Collateral and the disposition thereof, Coast is hereby granted a security
interest in, and Coast and any purchaser from Coast may use without charge, all
of the Borrower's plant, machinery, equipment, labels, licenses, processes,
patents, patent applications, copyrights, names, trade names, trademarks, trade
secrets, logos, advertising material and all other assets, and may also utilize
all of Borrower's rights under any license or franchise agreement; (f) Sell,
ship, reclaim, lease or otherwise dispose of all or any portion of the
Collateral in its condition at the time Coast obtains possession or after
further manufacturing, processing or repair, at any one or more public and/or
private sales (including execution 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 fit, 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 Accounts and general
intangibles comprising part or all of the 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 Accounts and the like for less than face value; (h) Demand and
receive possession of any of Borrower's federal and state income tax returns and
the Records utilized in the preparation thereof or referring thereto. All
attorneys' fees, expenses, costs, liabilities and obligations incurred by Coast
with respect to the foregoing shall be added to and become part of the
Obligations, shall be due on demand, and shall bear interest at a rate equal to
the highest interest rate applicable to any of the Obligations. 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.



                                      -14-
<PAGE>   15

                  6.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS.
Borrower and Coast agree that the following conduct by Coast with respect to any
disposition of Collateral shall conclusively be deemed commercially reasonable
(but other conduct by Coast, including, but not limited to, Coast's use in its
sole discretion of other or different times, places and manners of noticing and
conducting any disposition of Collateral shall not be deemed unreasonable): Any
public or private disposition as to which no later than the tenth calendar day
prior thereto written notice thereof is mailed or personally delivered to
(Borrower and, with respect to any public disposition, on no later than the
tenth calendar day prior thereto notice thereof describing in general
non-specific terms, then Collateral to be disposed of is published once in a
newspaper of general circulation in the county where the sale is to be
conducted, at any place designated by Coast, with or without the Collateral
being present, and which commences at any time between 8:00 a.m. and 5:00 p.m.
Without limiting the generality of the foregoing, Borrower expressly agrees
that, with respect to any disposition of Accounts, instruments and general
intangibles (collectively "Receivables"), it shall be commercially reasonable
for Coast to direct any prospective acquirer thereof to ascertain directly from
Borrower any and all information (and Coast shall not be required to maintain
records of, or answer any inquires) concerning the Receivables offered for
disposition, including, but not limited to, the terms of payment, aging and
delinquency, if any, of the Receivables, the financial condition of any obligor
or account debtor thereon or guarantor thereof, any collateral therefor and the
condition and location of the goods, if any, that are the subject of any of the
Receivables.

                  6.4 APPLICATION OF PROCEEDS. All proceeds realized as the
result of any disposition of the Collateral shall be applied by Coast first to
the costs, expenses, liabilities, obligations and attorneys' fees incurred by
Coast in the exercise of its rights under this Loan Agreement and any Collateral
Agreement, second to the interest due upon any of the Obligations and third to
the principal of the Obligations in any order determined by Coast in its sole
discretion. The surplus, if any, shall be paid to Borrower; if any deficiency
shall arise, Borrower shall remain liable to Coast therefor. If, as a result of
the disposition of any of the Collateral, Coast directly or indirectly enters
into a credit transaction with any third party, Coast shall have the option,
exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of such credit transaction or deferring the
reduction thereof until the actual receipt by Coast of cash therefor from such
third party.

                  6.5 REMEDIES CUMULATIVE. In addition to the rights and
remedies set forth in this Loan Agreement and any Collateral Agreement, Coast
shall have all the other rights and remedies accorded a secured party under the
California Uniform Commercial Code and under any and all other applicable laws
and in any other instrument or agreement now or hereafter 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.

7.       POWER OF ATTORNEY.



                                      -15-
<PAGE>   16

         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: (a) Execute on
behalf of Borrower any documents that Coast may, in its sole and absolute
discretion, deem advisable in order to perfect, maintain or improve Coast's
security interest in the Collateral or other real or personal property intended
to constitute Collateral, or in order to exercise a right of Borrower or Coast,
or in order to fully consummate all the transactions contemplated under this
Loan Agreement, any Collateral Agreement and all other present and future
agreements; (b) At any time after the occurrence of an Event of Default, to
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 Account, 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 assignment or satisfaction of
mechanic's, materialman's or other lien; (d) subject to the terms of this
Agreement and the Collateral Agreements 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) Upon the occurrence of any Event of
Default, to receive and open all mail addressed to Borrower; (f) Endorse all
checks and other forms of remittances received by Coast "Pay to the Order of
Coast Business Credit Corporation," or in such other manner as Coast may
designate; (g) after an Event of Default 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; (h) after an Event of Default Grant extensions
of time to pay, compromise claims and settle Accounts and the like for less than
face value and execute all releases and other documents in connection therewith;
(i) Pay any sums required on account of Borrower's taxes or to secure the
release of any liens therefor, or both; (j) Settle and adjust, and give releases
of, any insurance claim that relates to any of the Collateral and obtain payment
therefor; (k) 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 Paragraph 4.3 of
this Loan Agreement; and (l) Take any action or pay any sum required of Borrower
pursuant to this Loan Agreement, any Collateral Agreement and any other present
or future agreements. Any and all sums paid and any and all 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, shall be
payable on demand, and shall bear interest at a rate equal to the highest
interest rate applicable to any of the Obligations. In no event shall Coast's
rights under the foregoing power of attorney or any of Coast's other rights
under this Loan Agreement or any Collateral Agreement be deemed to indicate that
Coast is in control of the business, management or properties of Borrower.

8.       TERMINATION.

         This Loan Agreement and all Collateral Agreement(s) shall continue in
effect until June 19, 1998 (the "initial renewal date") and shall thereafter
automatically and continuously 



                                      -16-
<PAGE>   17

renew for successive additional terms of one year(s) each unless terminated as
to future transactions as--hereinafter provided so long as Borrower pays a
renewal fee of 0.5% of the Maximum Dollar Amount to Coast prior to the initial
renewal date and thereafter each subsequent anniversary thereof. (The initial
renewal date and each subsequent date on which the terms of this Loan Agreement
and the Collateral Agreement(s) automatically renew are hereinafter referred to
as "renewal dates.") This Loan Agreement and any Collateral Agreement may be
terminated, as to future transactions only, as follows: (a) By written notice
from either Coast or Borrower to the other, not less than one hundred twenty
(120) days prior to the next renewal date, in which event termination shall be
effective on the next renewal date; or ) By Coast at any tune after the
occurrence of an Event of Default, without notice, in which event termination
shall be effective immediately; or (c) By one hundred twenty (120) days' prior
written notice from Borrower to Coast, in which event, termination shall be
effective on the one hundred twentieth day after such notice is given; or (d) By
the grant by Borrower to any third party of a lien or encumbrance on, or
security interest in, any of the Collateral, as provided in Paragraph 3.5, in
which event termination shall be effective on the date selected by. Coast
pursuant to Paragraph 3.5. On the effective date of termination, Borrower shall
pay and perform in fill 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. If Borrower attempts to terminate this Loan
Agreement under subparagraph (a) or (c) above, but does not pay and perform all
Obligations in fill on the effective date of termination, then this Loan
Agreement and all Collateral Agreement(s) shall not be terminated and shall
continue in full force and effect until the next renewal date and shall
automatically renew thereafter as provided above. If termination occurs under
subparagraph (b), (c) or (d) above, Borrower shall pay to Coast a termination
fee in an amount equal to (ii) two percent (2%) of the Maximum Dollar Amount.
Said termination fee shall be included in the Obligations, shall be payable on
the effective date of termination, and shall bear interest at a rate equal to
the highest interest rate applicable to any of the Obligations. Without limiting
the generality of the foregoing, if on the initial renewal date or thereafter
any subsequent renewal 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, 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. Further, notwithstanding any
termination of this Loan Agreement or any Collateral Agreement, all of Coast's
security interest in all of the Collateral and all of the terms and provisions
of this Loan Agreement and all Collateral Agreement(s) shall continue in full
force and effect until all Obligations have been paid and performed in full, and
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. Without limiting
the fact that all Loans are discretionary on the part of Coast, Coast may, in
its sole discretion, refuse to make any further Loans after termination. Upon
payment and performance in fill of all the Obligations, Coast shall promptly
deliver to Borrower termination statements, request for reconveyances and such
other documents as may be required to fully terminate any of Coast's security
interests. Notwithstanding the foregoing, 



                                      -17-
<PAGE>   18

Borrower may not terminate this Agreement under subparagraph (a), (c) or (d)
above, unless Borrower also concurrently terminates the CEFO Agreement.

9.       NOTICES.

         All notices to be given hereunder shall be in writing and shall be
served either personally or by Federal Express or other recognized private
delivery service ("Private Delivery") or by depositing the same in the United
States mail, postage prepaid, by regular first-class mail, or by certified mail,
return receipt requested, addressed to Coast or Borrower at the addresses shown
above, or at any other address as shall be designated by one party in a written

prepaid (except that any notice of disposition referred to in Paragraph 6.3
hereof that is mailed shall be deemed given at the time of deposit thereof in
the United States mail, with postage prepaid). If there is more than one
Borrower, notice to any Borrower shall constitute notice to all; if Borrower is
a corporation, the service upon any member of the Board of Directors, officer,
employee or agent shall constitute service upon the corporation.

10.      GENERAL WAIVERS.

         The failure of Coast at any time or times hereafter to require Borrower
to strictly comply with any of the provisions of this Loan Agreement or any
Collateral Agreement or any other present or future agreement between Borrower
and Coast shall not waive or diminish any right of Coast thereafter to demand
and receive strict compliance therewith. Any waiver of any default shall not
waive or affect any other default, whether prior or subsequent thereto. None of
the provisions of this Loan Agreement or any Collateral Agreement or other
agreement now or hereafter 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 officer of Coast
and delivered to Borrower. Borrower waives the benefit of all statute(s) of
limitations in any action or proceeding based upon or arising out of this Loan
Agreement or any Collateral Agreement or any other present or future instrument
or agreement between Coast and Borrower. Borrower waives any and all notices or
demands which Borrower might be entitled to receive with respect to this Loan
Agreement, any Collateral Agreement, or any other agreement by virtue of any
applicable law. Borrower hereby 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 Loan Agreement or any
Collateral Agreement. Borrower hereby ratifies and confirms whatever Coast may
do in a commercially reasonable manner pursuant to this Loan Agreement and any
Collateral Agreement and agrees that Coast shall not be liable for (a) the
safekeeping of the Collateral or any loss or damage thereto, or diminution in
value thereof, from any cause 



                                      -18-
<PAGE>   19

whatsoever unless any damage thereto is caused by Coast's gross negligence or
willful misconduct, or (b) any act or omission of any carrier, warehouseman,
bailee, forwarding agent or other person, or (c) any act of commission or any
omission by Coast or its officers, employees, agents, or attorneys, or any of
its or their errors of judgment or mistakes of fact or law except for Coast's
gross negligence or willful misconduct.

11.      ATTACHMENT WAIVERS.

         To the extent that Coast, in its sole and absolute discretion,
determines, prior to the disposition of all of the Collateral, that the amount
to be realized by Coast from the disposition of all of the Collateral may be
less than the amount of the Obligations, and to the full extent of any such
anticipated deficiency, Borrower waives the benefit of Section 483.010(b) of the
California Code of Civil Procedure and of any and all other statutes requiring
Coast to first resort to and exhaust all of the Collateral before seeking or
obtaining any attachment remedy against Borrower, and Borrower expressly agrees
that, to the extent of such anticipated deficiency, Coast shall have all of the
rights of an unsecured creditor, including, but not limited to, the right of
Coast, prior to the disposition of all of the Collateral, to obtain a temporary
protective order and writ of attachment or other available remedy. Coast shall
have no liability to Borrower if the actual deficiency realized by Coast is less
than the anticipated deficiency on the basis of which Coast obtained a temporary
protective order or writ of attachment. In the event Coast should seek a
temporary protective order, or writ of attachment, or both, Borrower hereby
irrevocably waives any bond and any surety or security relating thereto required
by any statute, court rule or otherwise as an incident or condition precedent to
the issuance of any temporary protective order or writ of attachment.

12.      ATTORNEYS' FEES AND COSTS.

         Borrower shall forthwith pay to Coast the amount of all reasonable
attorneys' fees and all filing, recording, publication, search and other costs
incurred by Coast pursuant to this Loan Agreement, any Collateral Agreement or
any other present or future agreement or in connection with any transaction
contemplated hereby, or with respect to the Collateral or the defense or
enforcement of its interests (whether or not Coast files a lawsuit against
Borrower)**. Without limiting the generality of the foregoing, Borrower shall,
with respect to each and all of the foregoing, pay all attorneys' fees and costs
Coast incurs in order to: obtain legal advice; enforce, or seek to enforce, any
of its rights; prosecute actions against, or defend actions by, Account debtors;
commence, intervene in, respond to, or defend any action or proceeding; initiate
any complaint to be relieved of the effect of the automatic stay in bankruptcy
in order to commence or continue any foreclosure or other disposition of the
Collateral or to commence, defend or continue any action or other proceeding in
or out of bankruptcy against Borrower or relating to the Collateral; file or
prosecute a claim or right in any action or proceeding, including, but not
limited to, any probate claim, bankruptcy claim, third party claim, secured
creditor claim or reclamation complaint; examine, audit, count, test, copy, or
otherwise inspect any of the Collateral or any of Borrower's books and records;
or protect, obtain possession of lease, dispose of, or otherwise enforce any
security interest in or lien on, the Collateral or represent Coast in any
litigation with respect to Borrower's affairs. If either Coast or Borrower files
any lawsuit 



                                      -19-
<PAGE>   20

against the other predicated on a breach of this Loan Agreement or any
Collateral Agreement, the prevailing party in such action shall be entitled to
recover its costs and attorneys' fees, including, but not limited to, attorneys'
fees and costs incurred in the enforcement of, execution upon or defense of any
order, decree, award or judgment. All attorneys' fees and costs to which Coast
may be entitled pursuant to this Paragraph shall immediately become part of
Borrower's Obligations, shall be due on demand, and shall bear interest at a
rate equal to the highest interest rate applicable to any of the Obligations.

13.      DESTRUCTION OF BORROWER'S DOCUMENTS; LIMITATION OF ACTIONS.

         Any documents, schedules, invoices or other papers delivered to Coast
may be destroyed or otherwise disposed of by Coast six (6) months after they are
delivered to Coast unless Borrower makes written request therefor and pays all
expenses attendant to their return, in which event, Coast shall return same when
Coast's actual or anticipated need therefor has terminated. Borrower agrees that
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 Collateral Agreement, or any other
present or future 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, relating in
any way to Borrower, shall be barred unless asserted by Borrower by the delivery
of a specific written claim setting forth in reasonably specific detail the
Borrower's claim or cause of action within one year after the first act,
occurrence or commission upon which such claim or cause of action, or any part
thereof, is based. Borrower agrees that such one-year period of time is a
reasonable and sufficient time for Borrower to investigate and act upon any such
claim or cause of action. The six-month period provided herein shall not be
waived, tolled, or extended except by the written consent of Coast in its sole
and absolute discretion. This provision shall survive any termination, however
arising, of this Loan Agreement, any Collateral Agreement, and any other present
or future agreement.

14.      GENERAL PROVISIONS.

                  14.1 SEVERABILITY. Should any provision, clause or condition
of this Loan Agreement or any Collateral Agreement be held by any court of
competent jurisdiction to be void or unenforceable, such defect shall not affect
the remainder of this Loan Agreement or any Collateral Agreement.

                  14.2 INTEGRATION. This Loan Agreement and any Collateral
Agreements and such other agreements, documents and instruments as may be
executed in connection herewith shall be construed as the entire and complete
agreement between Borrower and Coast and shall supersede all prior negotiations,
all of which are merged and integrated herein.

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



                                      -20-
<PAGE>   21

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

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

                  14.6 JOINT AND SEVERAL LIABILITY. The liability of each
Borrower shall be joint and several and the compromise of any claim with, or the

used herein for convenience only. Borrower acknowledges that the same may not
describe completely the subject matter of the applicable paragraph, and the same

or provision hereof. This Loan Agreement and the Collateral Agreements have been
fully reviewed and negotiated between the parties and no uncertainty or
ambiguity in any term or provision of this Loan Agreement or any Collateral
Agreement shall he construed strictly against Coast or Borrower under any rule
of construction or otherwise.

                  14.8 GOVERNING LAW; JURISDICTION; VENUE. This Loan Agreement

rights and obligations of Coast and Borrower shall be governed by and in
accordance with the laws of the State of California. Any undefined term used in
this Loan Agreement or in any Collateral Agreement that is defined in the
California Uniform Commercial Code shall have the meaning therein assigned to
that term. As a material part of the consideration to Coast to enter into this
Agreement, Borrower (i) agrees that all actions and proceedings relating
directly or indirectly hereto shall, at Coast's option, be litigated in courts
located within California, and that the exclusive venue therefor shall be Los
Angeles County; (ii) consents to the jurisdiction and venue of any such court

delivery or any other method permitted by law; and (iii) waives any and all
rights Borrower may have to object to the jurisdiction of any such court, or to
transfer or change the venue of any such action or proceeding.

Collateral Agreement which has been executed and delivered by Borrower to Coast
shall not become effective unless and until executed by a duly authorized

continuing basis, to use reasonable efforts (but in no event less than the same
degree of care that it exercises with respect to its own proprietary information
of the same types) to maintain the confidentiality of and not to disclose to any
person other than its officers, directors, attorneys and accountants and
affiliates, and such other persons to whom Coast shall at any time be required
to make such disclosure in accordance with applicable law, any and all

COAST

     LOAN AND SECURITY AGREEMENT (CEFO FACILITY)

Borrower:         Catalyst Semiconductor, Inc.,
                  a Delaware corporation

Address:          1250 Borregas Avenue
                  Sunnyvale, California 94089

Date:             June 19, 1997

THIS LOAN AND SECURITY AGREEMENT ("Loan Agreement"), dated the above date, is
entered into at Los Angeles, California, between COAST BUSINESS CREDIT, a
division of Southern Pacific Thrift & Loan Association ("Coast"), a California
corporation, with offices at 12121 Wilshire Boulevard, Suite 1111, Los Angeles,
California 90025, and the borrower named above ("Borrower"), whose chief
executive office is located at the above address ("Borrower's Address").

* COAST AND THE BORROWER ARE ALSO PARTIES TO THAT CERTAIN LOAN AND SECURITY
AGREEMENT DATED JUNE 19, 1997 (THE "NONCEFO AGREEMENT") AND THE COLLATERAL
AGREEMENTS REFERRED TO THEREIN. BOTH THIS AGREEMENT AND THE NON-CEFO AGREEMENT
AND SUCH OTHER COLLATERAL AGREEMENTS SHALL CONTINUE IN FULL FORCE AND EFFECT,
AND ALL RIGHTS AND REMEDIES OF COAST HEREUNDER AND THEREUNDER ARE CUMULATIVE.

1.       LOANS.

         1.1 LOANS, COLLATERAL AGREEMENTS. Borrower has requested and may
hereafter request that Coast advance funds or otherwise extend credit to or for
the benefit of Borrower ("Loan(s)") in accordance with the terms and provisions
of this Loan Agreement and other written agreements ("Collateral Agreement(s)"),
including, but not limited to, any one or more of the following described
security agreements now or hereafter entered into between Borrower and Coast:
(a) CEFO Collateral Agreement and (d) any promissory notes or guaranties. The
amount and terms of payment of any Loans by Coast to Borrower shall be
determined in accordance with the terms and provisions of this Loan Agreement
and of any executed Collateral Agreements. Notwithstanding anything herein or in
any Collateral Agreement to the contrary, in no event shall the Borrower permit
the total balance of all Loans and all other Obligations (including without
limitation the Obligations under and as defined in the Non-CEFO Agreement)
outstanding at any one time to exceed $13,500,000 ("Maximum Dollar Amount");
and, if for any reason they do, Borrower shall immediately pay the amount of
such excess to Coast in immediately available funds.

         1.2 INTEREST. Unless specifically provided to the contrary in any
Collateral Agreement, all Loans shall bear interest at a rate equal to the

basis of a 360-day year for the actual number 


<PAGE>   2

of days elapsed; provided, however, all Loans shall bear interest at a rate
equal to the Prime Rate plus 1.75% per annum upon receipt of evidence acceptable
to Coast in its sole and absolute discretion that Borrower has achieved and
maintained a Tangible Net Worth (as that term is defined herein) of no less than
$17,000,000. 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 that month
shall be based on the highest "Prime Rate" in effect during said month, but in
no event shall the rate of interest charged on any Loans in any month be less
than 8% per annum. "Prime Rate" is defined as the actual "Reference Rate" or the
substitute therefor of the Bank of America NT&SA ("B of A") whether or not that
rate is the lowest interest rate charged by B of A. 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.

         1.3 FEES. Borrower shall pay to Coast a loan origination fee in the
amount of n/a concurrently herewith, and an annual loan fee of n/a on each
anniversary of the date hereof during the term of this Loan Agreement. Said fees
are in addition to all other sums payable to Coast, are not refundable for any
reason, and shall bear interest from the date due to the date paid at the
highest interest rate applicable to any of the Obligations.

         1.4 CONDITIONS PRECEDENT. The obligation of Coast to make the Loans is

Agreement duly executed and in form and substance satisfactory to Coast in its

                  (e) DAILY REMITTANCE. Coast shall have received evidence that
Borrower has established a procedure for (and borrower shall provide for) the
daily remittance to be collected either by payment in kind, blocked account, or
lockbox basis.

                  (f) SUBORDINATION. Borrower's debt, if any shall be

         3.1 CORPORATE EXISTENCE AND POWER. Borrower, if a corporation, is and
will continue to be, due authorized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Borrower and will continue to
be qualified and licensed to the business in all jurisdictions in which the
nature of its business transacted by it, or the ownership or leasing of its

                                      -4-
<PAGE>   5

         3.2 AUTHORITY. Borrower is, and will continue to be, authorized to
enter into, to grant security interests in its property pursuant to, and to
perform its obligations under, this Loan Agreement, any Collateral Agreement and
all other instruments and transactions contemplated herein. The execution,
delivery and performance by Borrower of this Loan Agreement, any Collateral
Agreement and all other instruments and transactions contemplated herein have
been validly authorized, are enforceable against the Borrower in accordance with
their terms, and do not violate any law or any provision of Borrower's Articles
of Incorporation, By-Laws and any Shareholder Agreements nor do they violate any
material provision of, nor will they result in acceleration under, any material
agreement, indenture, note or instrument which is binding upon Borrower, or any
of its property.

         3.3 NAME; TRADE NAMES AND STYLES. Borrower has set forth above its
correct name. Listed on the Schedule hereto are all prior names of Borrower and
each fictitious name, trade name and trade style by which Borrower has been, or
is now, known. Borrower shall provide Coast with fifteen (15) days' advance
written notice prior to doing business under any other name, fictitious name,
trade name or trade style. Borrower has complied, and will hereafter comply,
with all laws relating to the conduct of business under, the ownership of
property in, and the renewal or continuation of the right to use, a corporate,
fictitious or trade name or trade style.

         3.4 PLACE OF BUSINESS; LOCATION OF COLLATERAL. Borrower's sole place of
business; or, if Borrower has more than one place of business, Borrower's chief
executive office; or, if Borrower is an individual and does not have a separate
place of business, Borrower's residence is, and will continue to be, located at
Borrower's Address and all of Borrower's books and records, including, but not
limited to, the books and records relating to Borrower's Accounts, are and will
be maintained at Borrower's Address unless and until Coast shall otherwise
consent in writing. In addition to Borrower's Address, Borrower has places of
business and Collateral is located only at the locations shown on the Schedule
hereto. Borrower will provide Coast with at least fifteen (15) days' advance
written notice if Borrower moves any of the Collateral to any new location not
previously reported to Coast, or obtains any additional sites for the conduct of
Borrower's business or the location of any Collateral.

         3.5 THE TO COLLATERAL; LIENS. Borrower is now, and will at all times
hereafter be, the lawful and sole owner of all the Collateral. With the
exception of the security interest granted Coast, the Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims ("Liens"), other than Permitted Liens. As used
herein, "Permitted Liens" means (i) any Liens existing as of the date hereof and
disclosed in Schedule A hereto; (ii) Liens for taxes, fees, assessments or other
governmental charges or levies, either not delinquent or being contested in good
faith by appropriate proceedings, provided the same have no priority over any of
Coast's security interests; (iii) Liens of materialmen, mechanics, warehousemen,
carriers, or employees or other like Liens arising in the ordinary course of
business and securing obligations either not delinquent more than 45 days or
being contested in good faith by appropriate proceedings; (iv) any judgment,
attachment or similar lien, unless the judgment it secures is not fully covered
by insurance and has not been discharged or execution thereof effectively stayed
and bonded against pending appeal within 30 days of the entry thereof provided
that, if the judgment is not fully covered by insurance or 



                                      -5-
<PAGE>   6

execution thereof has not been so stayed and bonded, Coast shall not be required
to make any Loans or otherwise extend credit to or for the benefit of Borrower;
(v) Liens (i) upon or in any equipment acquired or to be acquired, held or
leased by the Borrower to secure the purchase price of such equipment or
indebtedness incurred solely for the purpose of financing the acquisition of
such equipment or (ii) existing on such equipment at the time of its acquisition
or lease, provided that the Lien is confined solely to the equipment so acquired
and improvements thereon; (vi) Leases or subleases and licenses or sublicenses
granted to others not interfering in any material respect with the business of
Borrower; (vii) Encumbrances securing reimbursement obligations of Borrower with
respect to commercial letters of credit, provided that such encumbrances shall
attach only to documents or other property relating to such letters of credit
and products and proceeds thereof that are not Collateral under this Agreement
or any of the Collateral Agreements subsequent to the delivery of such property
to Borrower; (viii) Liens incurred in connection with the extension, renewal or
refinancing of the indebtedness secured by Liens of the type described in
clauses (i) and (v) above, provided that any extension, renewal or replacement
Lien shall be limited to the property encumbered by the existing Lien and the
principal amount of the indebtedness being extended, renewed or refinanced does
not increase; (ix) Liens securing debt junior in perfection and priority to the
lien of Coast which are expressly subordinated to Coast on terms satisfactory to
Coast (including a provision stating that the secured party shall not take
action to enforce its lien so long as any of the Obligations remain
outstanding); (x) Liens in favor of customs and revenue authorities which secure
payment of customs duties in connection with the importation of goods; (xi)
Liens which constitute rights of set-off of a customary nature or bankers' liens
on amounts on deposit, whether arising by contract or by operation of law, in
connection with arrangements entered into with depository institutions in the
ordinary course of business; and (xii) other Liens in existence on the date
hereof and listed on Schedule A hereto. Without limiting any of Coast's other
rights and remedies, if Borrower grants any third patty a lien or encumbrance on
or security interest (other than a Permitted Lien) in any of the Collateral,
Coast, in its sole discretion, shall have the right to treat such action as a
notice of termination by Borrower to Coast under Paragraph 8(d) hereof, as of
any date subsequent to such grant selected by Coast, in its sole discretion, and
to charge Borrower the termination fee therein provided. Coast now has, and will
have, a perfected and enforceable first priority security interest in all of the
Collateral (Other than Collateral subject to a Permitted Lien) to the extent
that such security interest can be perfected by the filing of financing
statements and Borrower will at all times defend Coast and the Collateral
against all claims of others. 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 patty to execute and deliver to
Coast, in form acceptable to Coast, whatever waivers and subordinations that
Coast specifies, 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 except for leases of sales offices at which not 



                                      -6-
<PAGE>   7

more than $200,000 in Collateral is located.

         3.6 MAINTENANCE OF COLLATERAL. Borrower has maintained and will
maintain the Collateral and all of its assets in good working condition, at
Borrower's expense. Borrower will not use the Collateral or any of its other
properties for any unlawful purpose and will not secrete or abandon the
Collateral except for the abandonment of worn-out or obsolete equipment or
inventory in the ordinary course of business. Borrower will immediately advise
Coast in writing of any material loss or depreciation of the Collateral.

         3.7 BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address books and records which are complete and accurate in all
material respects and which comprise an accounting system in accordance with
generally accepted principles. Borrower has not and will not in the future enter
into any agreement with any accounting firm, service bureau or third parry to
prepare or store Borrower's books and records at any location other than
Borrower's Address, without first obtaining Coast's written consent, which may
be conditioned upon such accounting firm, service bureau or other third party
agreeing to give Coast the same rights with respect to access to books and
records and related rights as Coast has under Paragraph 4.3 of this Loan
Agreement.

         3.8 FINANCIAL CONDITION AND STATEMENTS. All financial statements now or
hereafter delivered to Coast have been, and will be, prepared in conformity with
generally accepted accounting principles and now and hereafter will fairly
reflect the financial condition of Borrower, at the times and for the periods
therein stated. Since the last date covered by any such statement, there has
been no material adverse change in the financial condition, operations or any
other status of the Borrower. Borrower is now and will continue to be solvent in
both the "equity" and "bankruptcy" sense. Borrower will deliver to Coast a copy
of all reports and financial statements pursuant to Schedule 42.

         3.9 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state or local law. Borrower has timely paid, and will timely
pay, all foreign, federal, state and local taxes, assessments, deposits and
contributions now or hereafter owed by Borrower. Borrower may defer payment of
any contested taxes provided that Borrower (i) in good faith contests Borrower's
obligation to pay such taxes by appropriate proceedings promptly and diligently
instituted and conducted, (ii) notifies Coast in writing of the commencement of
and any material development in such proceedings, and (iii) posts bonds or takes
any other steps required to keep such contested taxes from becoming a lien
(other than Permitted Liens) against or charge upon any of the Collateral or
other properties of Borrower. 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. 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 



                                      -7-
<PAGE>   8

plan which could result in any liability of Borrower, including, without
limitation, any liability to the Pension Benefit Guaranty Corporation or its
successors or any other governmental agency. When requested, Borrower will
furnish Coast with proof satisfactory to Coast of Borrower's making the payment
or deposit of all such taxes and contributions, such proof to be delivered
within five (5) days after the due date established by law for each such payment
or deposit. If Borrower fails or is unable to pay or deposit such taxes or
contributions, Coast may, but is not obligated to, pay the same and treat all
such advances as additional Obligations of Borrower. Such advances shall bear
interest at the highest interest rate applicable to any of the Obligations.

         3.10 COMPLIANCE WITH LAW. Unless noncompliance would not materially
adversely affect (i) Borrower's financial condition as reflected in its
financial statements previously delivered to Coast; (ii) Borrower's operations;
or (iii) Borrower's business, Borrower has complied, and will comply, with all
provisions of all 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, conduct and licensing of
Borrower's business and employment of Borrower's personnel.

         3.11 LITIGATION. There is no claim, suit, litigation, proceeding or
investigation pending or threatened by or against or affecting Borrower in any
court or before any regulatory commission, board or other governmental agency
(or any basis therefor known to borrower) which is reasonably likely to result,
either separately or in the aggregate, in any material adverse change in the
business or condition of Borrower, or in any impairment in the ability of
Borrower to carry on its business in substantially the same manner as it is now
being conducted involving any single claim of $50,000 or more, or involving
$100,000 or more in the aggregate. Borrower will immediately inform Coast in
writing of any claim, proceeding, litigation or investigation hereafter
threatened or instituted by or against Borrower involving any single claim of
$50,000 or more, or involving $100,000 or more in the aggregate.

         3.12 USE OF PROCEEDS. 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." All proceeds of all Loans
shall be used solely for lawful business purposes.

         3.13 CONTINUING EFFECT. All representations, warranties and covenants
of Borrower contained in this Loan Agreement and any Collateral Agreement and
any other agreement with Coast shall be true and correct at the time of the
effective date of each such agreement and shall be deemed continuing and shall
remain true, correct and in full force and effect until payment and satisfaction
in full of all of the Obligations, and Borrower acknowledges that Coast is and
will be expressly relying on such representations, warranties and covenants in
making Loans to Borrower.

         4.1 INSURANCE. Borrower shall, at all times, at Borrower's expense,
insure all of the Collateral and carry such other business insurance with
insurers reasonably acceptable to Coast, 



                                      -8-
<PAGE>   9

in such form and amounts as Coast may reasonably require. All such insurance
policies shall name Coast as an additional loss payee, shall provide that
proceeds payable thereunder be payable directly to Coast unless written
authority to the contrary is obtained, and shall also provide that no act or
default of Borrower or any other person shall affect the right of Coast to
recover thereunder and shall contain a lenders loss payee endorsement in form
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 and absolute discretion provided that if (I) no Event of
Default has occurred and is continuing, and (ii) the proceeds are less than
$50,000 and (iii) the proceeds relate to Collateral which Is not inventory to be
untitled to fulfill "Eligible Purchase Orders" (as defined in the CEFO
Collateral Agreement of even date), then Coast shall release the same to the
Borrower for the repair or replacement of the property affected. If Borrower
fails to provide or pay for any such insurance, Coast may, but is not obligated
to, procure the same at Borrower's expense. Borrower agrees to deliver to Coast,
promptly as rendered, copies of all material reports made to all insurance
companies.

         4.2 REPORTS. At its expense, Borrower shall report, in form
satisfactory to Coast, such information as Coast may from time to time

reports furnished Coast shall be complete and accurate in all material respects.

agents, shall have immediate access to the Collateral and any other property of
Borrower, wherever located provided that if no Event of Default has occurred and
is continuing, such access shall be on one business days notice and during
normal business hours. Coast shall have the right to audit and copy Borrower's
books and records and accounts including accountants' reports wherever located
(hereinafter collectively the "Records"). Such audits shall be at Borrower's
expense and the charge for the audits shall be $750 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. Borrower hereby irrevocably authorizes and
directs any of the officers, agents, accountants and attorneys having possession
or control of any of the Records (including computer records) to physically
deliver or make same available to Coast upon Coast's request. Coast shall have
the right to possession of, or to move to the premises of Coast or any agent of
Coast, for so long as Coast may desire, all or any part of the Records. All of
the rights of Coast under this Section 4 shall be subject to the provisions of
Section 14.11 of this Agreement.

         4.4 PROHIBITED TRANSACTIONS. Borrower shall not without Coast's prior
written consent, merge, consolidate, dissolve, acquire any other corporation;

                                      -9-
<PAGE>   10

payment for deposit to the general account of Borrower or which are transmitted
or turned over to Coast on account of the Obligations); pay or declare any
dividends upon Borrower's stock; except that Borrower may repurchase or redeem
shares of its capital stock pursuant to employee option plans for an aggregate
purchase price not to exceed S100,000 per fiscal year, on a non-cumulative basis
redeem, retire, purchase or otherwise acquire, directly or indirectly, any of
Borrower's stock; make any change in Borrower's name, identity, corporate or
capital structure (except that Borrower may issue common stock upon exercise of
stock options, sell shares of its capital stock for cash, and issue convertible
debentures subordinate in all respects to the Obligations pursuant to
subordination provisions acceptable to Coast in its discretion); sell or
transfer any Collateral, except for the sale of furnished inventory in the
ordinary course of Borrower's business and except that, provided no Event of
Default has occurred and is continuing, Borrower may sell excess equipment in
the ordinary course of business in good faith arm's length transactions, and
retain the proceeds thereof for use in its business; lend or distribute any of
Borrower's property or assets, or incur any debts, outside of the ordinary
course of Borrower's business.

         4.5 NOTIFICATION OF CHANGES. Borrower will promptly notify Coast in
writing of any change of its officers, directors, the death of any partner or
joint venturer, any purchase in excess of $50,000 out of the regularly course of
Borrower's business without Coast's consent and any adverse or material change
in the business or financial affairs of Borrower.

         4.6 CHARGES. Borrower shall pay all charges assessed by Coast, in
accordance with Coast's schedule of charges in effect from time to time, and
such charges shall be part of the Obligations and shall be payable on demand.

by or against Coast with respect to any Collateral or for the collection or
enforcement of any Account, or in any manner relating to Borrower, Borrower
shall, without expense to Coast, and wherever and whenever designated by Coast,
make available Borrower and its officers, employees and agents and Borrower's
Records to the extent that Coast may deem necessary in order to prosecute or
defend any such suit or proceeding.

         4.8 REMITTANCE OF PROCEEDS. All proceeds arising from the disposition
of the Collateral shall be delivered, in kind, by Borrower to Coast in the
original form in which received by Borrower not later than the following
business day after receipt by Borrower except (i) wire transfer remittances
received by Borrower shall be transmitted to Coast in total the day following
posting to Borrower's bank account. Borrower agrees that it will not commingle
proceeds of Collateral with any of Borrower's other fluids or property, but will
hold such proceeds separate and apart from such other funds and property and in
an express trust for Coast. Coast may from time to time verify directly with the
respective account debtors the validity, amount and any other matters relating
to the Accounts 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 EXECUTE ADDITIONAL DOCUMENTATION. Borrower agrees, at its expense,
on demand by Coast, to execute all documents in form satisfactory to Coast, as
Coast, in its sole discretion, 



                                      -10-
<PAGE>   11

may deem reasonably necessary or useful in order to perfect and maintain Coast's
perfected first-priority or any other security interest in the Collateral, and
in order to fully consummate all of the transactions contemplated under this
Loan Agreement and under any Collateral Agreement.

         4.10 TANGIBLE NET WORTH. Borrower shall maintain, at all times at which

after receipt by Coast as to uncollected fluids and zero days after receipt of
collected (goods) fluids in order to allow for clearance, bookkeeping and
computer entries. All payments made by Borrower may be applied, and in Coast's
sole discretion reversed and re-applied, in whole or in part to any of the
Obligations, in such order and manner as Coast shall determine in its sole
discretion.

6.       EVENTS OF DEFAULT AND REMEDIES.

time thereafter, Coast, at its option, and without notice or demand of any kind
(all of which are hereby expressly waived by Borrower) (except that, prior to or

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 fit, 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

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

expenses, costs, liabilities and obligations incurred by Coast with respect to
the foregoing shall be added to and become part of the Obligations, shall be due
on demand, and shall bear interest at a rate equal to the highest interest rate
applicable to any of the Obligations. 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.

         6.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and
Coast agree that the following conduct by Coast with respect to any disposition
of Collateral shall conclusively be deemed commercially reasonable (but other
conduct by Coast, including, but not limited to, Coast's use in its sole
discretion of other or different times, places and manners of noticing and
conducting any disposition of Collateral shall not be deemed unreasonable): Any
public or private disposition as to which on no later than the tenth calendar
day prior thereto written notice thereof is mailed or personally delivered to
Borrower and, with respect to any public disposition, on no later than the tenth
calendar day prior thereto notice thereof describing in general non-specific
terms, the Collateral to be disposed of is published once in a newspaper of
general circulation in the county where the sale is to be conducted, at any
place designated by Coast, with or without the Collateral being present, and
which commences at any time between 8:00 p.m. and 5:00 p.m. Without limiting the
generally of the foregoing, Borrower expressly agrees that, with respect to any
disposition of Accounts, instruments and general intangibles (collectively
"Receivables"), it shall be commercially reasonable for Coast to direct any
prospective acquirer thereof to ascertain directly from Borrower any and all
information (and Coast shall not be required to maintain records of, or answer
any inquiries) concerning the Receivables offered for disposition, including,
but not limited to, the terms of payment, aging and delinquency, if any, of the
Receivables, the financial condition of any obligor or account debtor thereon or
guarantor thereof, any collateral therefor and the condition and location of the
goods, if any, that are the subject of any of the Receivables.

         6.4 APPLICATION OF PROCEEDS. All proceeds realized as the result of any
disposition of the Collateral shall be applied by Coast first to the costs,
expenses, liabilities, obligations and attorneys' fees incurred by Coast in the
exercise of its rights under this Loan Agreement and any Collateral Agreement,
second to the interest due upon any of the Obligations and third to the
principal of the Obligations in any order determined by Coast in its sole
discretion. The surplus, if any, shall be paid to Borrower; if any deficiency
shall arise, Borrower shall remain liable to Coast therefor. If, as a result of
the disposition of any of the Collateral, Coast directly or indirectly enters
into a credit transaction with any third patty, Coast shall have the option,
exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of such credit transaction or deferring the
reduction thereof until the actual receipt by Coast of cash therefor from such
third party.

         6.5 REMEDIES CUMULATIVE. In addition to the rights and remedies set
forth in this Loan Agreement and any Collateral Agreement, Coast shall have all
the other rights and remedies accorded a secured party under the California
Uniform Commercial Code and under any and all other applicable laws and in any
other instrument or agreement now or hereafter entered into between Coast and
Borrower and all of such rights and remedies are cumulative and



                                      -14-
<PAGE>   15

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 copy 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.

Coast's other rights under this Loan Agreement or any Collateral Agreement be
deemed to indicate that Coast is in control of the business, management or
properties of Borrower.

         THIS VARIATION AGREEMENT is made the 16th day of April One Thousand
Nine Hundred and Ninety-Eight (1998) Between:-

A.       CATALYST SEMICONDUCTOR, INC ("CSI") of Delaware, U.S.A. corporation,
         having its principal place of business at 1250 Borregas Avenue,
         Sunnyvale, California 94089, U.S.A. and

B.       TRIO-TECH INTERNATIONAL PTE LTD ("TTI") having its principal place of
         business at 5 Kian Teck Road, Singapore 628765

WHEREAS:

1.       CSI and TTI have entered into an agreement on 23 March 1998 in
         accordance the terms and conditions contained therein. A copy of the
         said agreement is attached hereto marked as Annex A ("supply
         agreement"). The said agreement is a back to back agreement with an
         agreement which TTI is required to enter into with OKI Electronics
         Industry Co. Ltd ("OKI") to procure the sale and supply of wafer to CSI
         ("purchase agreement"). Clause 2.1 of the purchase agreement provides
         that TTI shall only forward payment to OKI after receiving full payment
         from CSI. In consideration of TTI agreeing to vary the purchase
         agreement with OKI by deleting clause 2.1 thereof, CSI has agreed to
         enter into this variation agreement. A copy of the purchase agreement
         containing clause 2.1 is attached hereto marked as Annex B. A copy of
         the executed purchase agreement as amended by deleting clause 2.1 is
         attached hereto marked as Annex C.

2.       CSI and TTI have mutually agreed to vary the terms of the said
         agreement in accordance with the terms and conditions hereunder.

IT IS HEREBY AGREED AS FOLLOW:

1.       In consideration of TTI agreeing to vary the purchase agreement with
         OKI by deleting clause 2.1 of the purchase agreement which reads "TTI
         shall only forward payment to OKI after receiving full payment from
         CSI", CSI hereby covenant that it will make full payment of all wafers
         supplied to them by OKI regardless of any defect, damage, delay in
         delivery or any discrepancy whatsoever relating to the wafers. CSI will
         further indemnify TTI from and against all or any claim, damage or loss
         which TTI may suffer by reason of any dispute CSI may have against OKI
         in respect of the sale and supply of wafers. CSI will further hold TTI
         harmless from any liability for any defect, damage, delay in delivery
         or any discrepancy 


<PAGE>   9


         whatsoever arising from the supply of the wafers. For the avoidance of
         doubt, TTI shall be entitled and shall not be in breach of the supply
         agreement by releasing full payment to OKI of all wafers supplied by
         them notwithstanding the presence of any defect, damage, delay in
         delivery or any discrepancy whatsoever relating to the wafers.

2.       Clause 3.1 of the supply agreement refers to U.S one million dollars
         worth of "inventory at Trio-Tech's facilities in Bangkok, Thailand
         ..........." For the avoidance of doubt and for consistency, it is
         hereby clarified that reference to "inventory" shall be reference to
         "work-in-progress".

3.       Clause 4.1(a) of the supply agreement provides as follow:-

         "TTI will take possession of the inventories assigned to them under
         clause 3.1 subject to the senior right of Coast Business Credit"

         CSI is aware of the dilution of the above security. In consideration of
         TTI agreeing to vary their contract with OKI in accordance with clause
         1 above, the parties have therefore mutually agreed to vary the supply
         agreement in accordance with the terms hereunder. CSI warrants that
         they have legal title in the work in progress of the semiconductors
         which are in the custody of Trio-Tech (Bangkok) Co. Ltd in Thailand.
         CSI hereby agrees that in the event of any default by them under the
         supply agreement and in particular to the failure by CSI to make
         payment when due, TTI shall be entitled to sell, dispose or compel the
         sale of the work in progress held by Trio-Tech (Bangkok) Co. Ltd for
         the purpose of compensating them in respect of the loss sustained by
         TTI by reason of CSI's default. CSI further covenants that in the event
         that the right to sell the work in progress arises, they will do all
         that is necessary for the purpose of transferring title in the work in
         progress to any third party on the instructions of TTI and will in
         addition authorise Trio-Tech (Bangkok) Co. Ltd to assist and effect the
         sale or disposal. PROVIDED THAT, TTI shall only be entitled to sell
         such work in progress as is necessary to compensate them for their loss
         sustained by reason of CSI's default which said sum shall not exceed
         US$1 million (US one million dollars).

     A. The Company and the Rights Agent are parties to a Preferred Shares
Rights Agreement dated as of December 3, 1996 (the "RIGHTS AGREEMENT").

     B. Elex N.V. ("ELEX") and the Company are entering into a Common Stock

the Purchase Agreement and the transactions contemplated thereby.

     C. Pursuant to Section 27 of the Rights Agreement, the Board of Directors
of the Company has determined that an amendment to the Rights Agreement as set

amended to add the following sentence at the end thereof:

     "Notwithstanding anything in this Rights Agreement to the contrary, Elex
     N.V. ("ELEX") shall not be deemed to be an Acquiring Person solely by
     virtue of the announcement, occurrence or continuance of (i) the execution
     of the Common Stock Purchase Agreement dated as of May 26, 1998 between
     Elex and the Company (the "PURCHASE AGREEMENT"), (ii) the issuance to Elex
     of 1,500,000 shares of Common Stock of the Company in accordance with the
     terms of the Purchase Agreement (the "PERMITTED SHARES"), (iii) the
     consummation of any and all other transactions contemplated by the Purchase
     Agreement, or (iv) Elex holding the Permitted Shares; provided, however,
     that if Elex and its Affiliates, at any time after consumation of the
     transactions contemplated by the Purchase Agreement and the issuance of the
     Permitted Shares, collectively shall be or become the Beneficial Owner of
     shares of Common Stock of the Company other than the Permitted Shares, then
     Elex's exemption from being deemed an Acquiring Person contained in this
     sentence shall not be applicable.


                                      -1-

     2. Effectiveness. This Amendment shall be deemed effective as of May 22,
1998 as if executed on such date. Except as amended hereby, the Rights Agreement
shall remain in full force and effect and shall be otherwise unaffected hereby.

     3. Miscellaneous. This Amendment shall be deemed to be a contract made
under the laws of the State of California and for all purposes shall be governed
by and construed in accordance with the laws of such state applicable to
contracts to be made and performed entirely within such state. This Amendment
may be executed in any number of counterparts, each of such counterparts shall
for all purposes be deemed to be an original, and all such counterparts shall
together constitute but one and the same instrument. If any provision, covenant
or restriction of this Amendment is held by a court of competent jurisdiction or
other authority to be invalid, illegal or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Amendment shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

         The parties hereby agree as follows:

         1.       PURCHASE AND SALE OF COMMON STOCK.

                  1.1 SALE AND ISSUANCE OF COMMON STOCK. Subject to the terms
and conditions of this Agreement, Purchaser agrees to purchase at the Closing

                  1.2 CLOSING; DELIVERY.

                           (a) The purchase and sale of the Stock shall take

                           (b) At the Closing, the Company shall deliver to

         2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
represents and warrants to Purchaser that, except as set forth on a Schedule of
Exceptions attached hereto as Exhibit A, which exceptions shall be deemed to be
representations and warranties as if made hereunder:

is a corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware and has all requisite corporate power and
authority to carry on its business. The Company is duly qualified to transact
business and is in good standing in each jurisdiction in which the failure so to

                           (b) 25,000,000 shares of Common Stock, 8,445,443

fully paid and are nonassessable and issued in compliance with all applicable
federal and state securities laws.

                           (c) Except for outstanding options, shares, rights or
other securities issued or granted pursuant to the Company's Stock Option Plan,

such company, there are no outstanding options, warrants, rights (including
conversion or preemptive rights and rights of first refusal or similar rights)
or agreements, orally or in writing, for the purchase or acquisition from the
Company of any shares of its capital stock.

                  2.3 AUTHORIZATION. All corporate action on the part of the
Company, its officers, directors and stockholders necessary for the

Agreement, the "AGREEMENTS"), the performance of all obligations of the Company
hereunder and thereunder and the authorization, issuance and delivery of the
Stock has been taken or will be taken prior to the Closing, and the Agreements,
when executed and delivered by the Company, shall constitute valid and legally
binding obligations of the Company, enforceable against the Company in
accordance with their terms except as limited by applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance, and other laws of
general application affecting enforcement of creditors' rights generally, as
limited by laws relating to the availability of specific performance, injunctive
relief, or other equitable remedies.

                  2.4 VALID ISSUANCE OF SECURITIES. The Stock that is being

part upon the representations of Purchaser in this Agreement and subject to the
provisions of Section 2.5 below, the Stock will be issued in compliance with all
applicable federal and state securities laws.

                  2.5 GOVERNMENTAL CONSENTS. No consent, approval, order or

<PAGE>   6

Section 25102(f) of the California Corporate Securities Law of 1968, as amended,
and the rules thereunder, other applicable state securities laws and Regulation
D of the Securities Act of 1933, as amended (the "SECURITIES ACT") and filings
required to be made with the National Association of Securities Dealers, Inc.
and The Nasdaq National Market.

                  2.6 LITIGATION. There is no action, suit, proceeding or
investigation pending or, to the Company's knowledge, currently threatened
against the Company or any of its subsidiaries that questions the validity of
the Agreements or the right of the Company to enter into them, or to consummate
the transactions contemplated hereby or thereby, nor is the Company aware that
there is any basis for the foregoing. The Company is not a party or subject to
the provisions of any order, writ, injunction, judgment or decree of any court
or government agency or instrumentality.

                  2.7 CORPORATE DOCUMENTS. The Restated Certificate of
Incorporation and Bylaws of the Company are in the form provided to Purchaser.

         3. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser hereby
represents and warrants to the Company that:

                  3.1 AUTHORIZATION; SHARE OWNERSHIP. Purchaser has full power
and authority to enter into the Agreements. The Agreements, when executed and
delivered by Purchaser, will constitute valid and legally binding obligations of
Purchaser, enforceable in accordance with their terms, except as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance, and any other laws of general application affecting enforcement of
creditors' rights generally, and as limited by laws relating to the availability
of a specific performance, injunctive relief, or other equitable remedies.
Purchaser does not, and immediately prior to the Closing will not, beneficially
own any outstanding shares of Common Stock of the Company

                  3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made
with Purchaser in reliance upon Purchaser's representation to the Company, which
by Purchaser's execution of this Agreement, Purchaser hereby confirms, that the
Stock to be acquired by Purchaser will be acquired for investment for
Purchaser's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof, and that Purchaser has no present
intention of selling, granting any participation in, or otherwise distributing
the same. By executing this Agreement, Purchaser further represents that
Purchaser does not presently have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participations to such
person or to any third person, with respect to any of the Stock. Purchaser has
not been formed for the specific purpose of acquiring the Stock.

                  3.3 DISCLOSURE OF INFORMATION. Purchaser has had an
opportunity to discuss the Company's business, management, financial affairs and
the terms and conditions of the offering of the Stock with the Company's current
and past Chief Executive Officers and other management and has had an
opportunity to review the Company's facilities, public filings and all other
materials requested by Purchaser and believed by Purchaser to be material to its
investment decision. Purchaser understands that such discussions, as well as any
other written information 

                                      -3-


<PAGE>   7

delivered by the Company to Purchaser, were intended to describe the aspects of
the Company's business which it believes to be material. Purchaser has had the
ability and opportunity to discuss such matters with legal and other advisors of
its choosing.

                  3.4 RESTRICTED SECURITIES. Purchaser understands that the
Stock has not been, and will not be, registered under the Securities Act, by
reason of a specific exemption from the registration provisions of the
Securities Act which depends upon, among other things, the bona fide nature of
the investment intent and the accuracy of Purchaser's representations as
expressed herein. Purchaser understands that the Stock constitutes "restricted
securities" under applicable U.S. federal and state securities laws and that,
pursuant to these laws, Purchaser must hold the Securities indefinitely unless
they are registered with the Securities and Exchange Commission and qualified by
state authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Securities for resale. Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Stock, and
on requirements relating to the Company which are outside of Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

                  3.5 NO PUBLIC MARKET. Purchaser understands that no public
market now exists for any of the securities issued by the Company, and that the
Company has made no assurances that a public market will ever exist for the
Securities.

                  3.6 LEGENDS. Purchaser understands that the Securities and any
securities issued in respect of or exchange for the Securities, may bear one or
all of the following legends:

                           (a) "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE
         NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
         ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH,
         THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE
         EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR
         AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH
         REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933."

                           (b) "THE SALE, PLEDGE OR TRANSFER OF THE SECURITIES
         REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS
         OF A CERTAIN COMMON STOCK PURCHASE AGREEMENT, AS AMENDED, BY AND
         BETWEEN THE SHAREHOLDER AND THE CORPORATION. COPIES OF SUCH AGREEMENT
         MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE
         CORPORATION."

                           (c) Any legend set forth in the other Standstill
         Agreement.

         In connection with negotiations relating to the proposed issuance by
Catalyst and purchase by Purchaser of shares of Catalyst's Common Stock,
Purchaser desires to make certain covenants to Catalyst so as to provide limits
on Purchaser's ownership of and voting of its capital stock of Catalyst.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
promises herein contained, the parties agree as follows:

                                A G R E E M E N T

         1. Certain Definitions. Unless the context otherwise requires, the
following terms, for all purposes of this Agreement, shall have the meanings
specified in this Section 1:

         "AFFILIATE" of any Person shall mean: (i) any entity which owns fifty
percent (50%) or more of such Person's Outstanding Voting Stock or which has the
power to appoint or elect a majority of the Board of Directors of such Person;
(ii) any entity in which such Person owns fifty percent (50%) or more of such
entity's Outstanding Voting Stock or for which such Person has the power to
appoint or elect a majority of the Board of Directors of such entity; (iii) any
entity having a common stockholder with such Person wherein such stockholder
owns fifty percent (50%) or more of such entity's Outstanding Voting Stock and
has the power to appoint a majority of the Board of Directors of such Person;
(iv) any entity having a common stockholder with such Person wherein such
stockholder owns fifty percent (50%) or more of such Person's Outstanding Voting
Stock and has the power to appoint a majority of the Board of Directors of such
entity; or (v) any entity having a common stockholder with such Person wherein
such stockholder has the power to appoint a majority of the Board of Directors
of such Person and such entity.

         "OUTSTANDING VOTING STOCK" of Catalyst, or another entity as the
context requires, shall mean the Common Stock of Catalyst (or such other entity)
and any other securities convertible into Common Stock of Catalyst (or such
other entity) having the power to vote in the election of directors of Catalyst
(or such other entity) then outstanding, other than securities having such power
only upon the happening of a contingency which has not yet occurred.

         "PERSON" shall mean any individual, partnership, joint venture,
corporation, trust or unincorporated organization, or any business entity or
governmental authority, in any case whether acting in an individual, fiduciary
or other capacity.
<PAGE>   18

         "VOTING POWER" shall mean the number of votes entitled to then be cast
by the Outstanding Voting Stock of Catalyst at any election of directors of
Catalyst, provided that, for the purpose of determining Voting Power, each share
of Preferred Stock of Catalyst, if any (the "PREFERRED STOCK"), shall be deemed
to be entitled to the number of votes equal to the number of shares of Common
Stock of Catalyst (the "COMMON STOCK") into which such share of Preferred Stock
could then be converted.

         "VOTING STOCK" shall mean the Common Stock outstanding, assuming the
exercise or conversion of all outstanding securities convertible into or
exercisable or exchangeable for Common Stock and further assuming the issuance
of all shares of Common Stock reserved for issuance pursuant to stock options
whether or not yet granted, and any other securities issued by Catalyst having
the power to vote in the election of directors of Catalyst, other than
securities having such power only upon the happening of a contingency which has
not yet occurred.

                  2.1. Standstill Provisions. Purchaser shall not (and shall not

other securities convertible into or exchangeable or exercisable for Voting
Stock, beneficial ownership of any Voting Stock, any securities convertible into
or exchangeable for Voting Stock, or any other right to acquire Voting Stock
(except, in any case, by way of stock dividends, stock splits or other
distributions made to holders of any Voting Stock generally), or authorize or
make a tender, exchange or other offer which would result in such an
acquisition, without the prior written consent of Catalyst approved by the Board
of Directors of Catalyst, if the effect of such acquisition would be to increase
the Voting Power of all Voting Stock then beneficially owned by Purchaser (and
its Affiliates), or which Purchaser (and its Affiliates) collectively have a
right to acquire, to more than 1,500,000 shares (as appropriately adjusted for
stock dividends, stock splits, recapitalizations, reclassifications and the
like);

                           (b) deposit any shares of Voting Stock in a voting
trust or subject any Voting Stock to any arrangement or agreement with respect
to the voting of such Voting Stock;

                           (c) otherwise act to seek to control the management,
Board of Directors, or policies of Catalyst (or any of its Affiliates), or,
except as required by law, make public statements with respect thereto;

                           (d) solicit, or induce others to solicit, "proxies"
to vote with respect to any securities issued by Catalyst or any of its
Affiliates, or become a "participant" or induce others to become a "participant"

14A under the Securities Exchange Act of 1934) securities issued by Catalyst (or
any of its Affiliates) or seek to advise or influence any Person with respect to
the voting of securities issued by Catalyst (or its Affiliates); or

<PAGE>   19

                           (e) otherwise act in any manner, whether by forming,
joining or participating with any Person or group, or aiding, advising,
encouraging or assisting any other Person or group, whether for the purpose of
acquiring, holding, voting or disposing of Voting Stock or accomplishing any of
the foregoing (a) through (d) above,, including inviting, encouraging,
soliciting or providing information to assist the submission of any proposal for
the acquisition, by purchase or otherwise, from Catalyst (or any of its
Affiliates) or any other Person of securities issued by Catalyst (or any of its
Affiliates) or assets of Catalyst (or any of its Affiliates) or any proposal
with respect to any form of restructuring, recapitalization or similar
transaction of Catalyst (or any of its Affiliates).

                  2.2. Notice of Purchases. Purchaser shall notify Catalyst in
writing as to Purchaser's (or any Affiliate's) acquisition of additional shares
of Voting Stock, or rights thereto within a reasonable time period not to exceed

in excess of one hundred thousand (100,000) Common Shares to any other party (or
any Affiliate of such party) in a transaction or a series of related
transactions without such other party which purchases such shares having agreed
to and having become a party to this Agreement with the Company.

         3. Voting of Stock. Purchaser (a) will execute all "proxies" solicited
by management or the Board of Directors of Catalyst or (b) will vote all Voting
Stock "FOR" all proposals submitted by Management or the Board of Directors of
Catalyst, for approval or a vote by the shareholders of Catalyst, including all
nominations for the Board of Directors of Catalyst.

         4. Prohibited Transfer. Any purchase which causes Purchaser to be in
violation of the terms of Section 2 above ("PROHIBITED TRANSFER") shall not be
effected by Catalyst and shall be voidable at the option of Catalyst by their
giving written notice to the transferor, his transferee and Purchaser. Each
certificate representing Common Shares held by Purchaser shall be endorsed by
the Company with a legend reading as follows:

         "THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A STANDSTILL AGREEMENT BY
         AND BETWEEN THE COMPANY AND THE HOLDER HEREOF (A COPY OF WHICH MAY BE
         OBTAINED FROM THE COMPANY), AND NO TRANSFER OF THE SHARES EVIDENCED

<PAGE>   24


                          CATALYST SEMICONDUCTOR, INC.

                             NONDISCLOSURE AGREEMENT


         This AGREEMENT is made as of May 26, 1998 between CATALYST
SEMICONDUCTOR, INC., a corporation organized and existing under the laws of the
State of Delaware ("CATALYST"), and ELEX N.V., a corporation organized and
existing under the laws of the Country of Belgium ("RECIPIENT").

         1. Purpose. Catalyst and Recipient wish to explore a possible business
relationship regarding an investment in Catalyst by Recipient (the
"RELATIONSHIP") in connection with which Catalyst may disclose its Confidential
Information to Recipient.

         2. Definition of Confidential Information. "CONFIDENTIAL INFORMATION"
means any information, technical data, or know-how, including, but not limited
to, that which relates to research, product plans, products, services,
customers, markets, software, developments, inventions, processes, designs,
drawings, engineering, hardware configuration information, marketing or finances
of the disclosing party, which Confidential Information is designated in writing
to be confidential or proprietary, or if given orally, is confirmed promptly in
writing as having been disclosed as confidential or proprietary. Confidential
Information does not include information, technical data or know-how which (i)
is in the possession of the receiving party at the time of disclosure as shown
by the receiving party's files and records immediately prior to the time of
disclosure, or (ii) prior to or after the time of disclosure becomes part of the
public knowledge or literature other than as a result of any improper inaction
or action of the receiving party, (iii) is approved by the disclosing party, in
writing, for release, or (iv) is required to be disclosed by applicable law or
proper legal, governmental or other competent authority (provided that Catalyst
shall be notified sufficiently in advance of such requirement so that it may
seek a protective order (or equivalent) with respect to such disclosure, which
Recipient shall fully comply with).

         3. Nondisclosure of Confidential Information. Recipient agrees not to
use any Confidential Information disclosed to it by Catalyst for Recipient's own
use or for any purpose except to carry out discussions concerning, and the
undertaking of, the Relationship. Recipient will not disclose any Confidential
Information of Catalyst to third parties or employees of Recipient, except
employees who are required to have the information in order to carry out the
discussions regarding the Relationship. Recipient agrees that it will take all
reasonable measures to protect the secrecy of and avoid disclosure or use of
Confidential Information of Catalyst in order to prevent it from falling into
the public domain or the possession of persons other than those persons
authorized hereunder to have any such information. Such measures shall include,
but not be limited to, the highest degree of care that the Recipient utilizes to
protect its own Confidential Information of a similar nature. Recipient has had
or will have employees to whom Confidential Information of Catalyst is disclosed
or who have access to Catalyst's Confidential Information sign a nondisclosure
agreement in content substantially similar to this Agreement 

                                      -1-


<PAGE>   25

and, at the request of Catalyst, will promptly notify Catalyst in writing of the
names of the persons who have signed such agreements. Recipient agrees to notify
Catalyst in writing of any misuse or misappropriation of Confidential
Information of Catalyst which may come to the Recipient's attention.

         4. Return of Materials. Any materials or documents which have been
furnished by Catalyst to the Recipient in connection with the Relationship will
be promptly returned by the Recipient, accompanied by all copies of such
documentation, within ten (10) days after (i) the Relationship has been
terminated or (ii) the written request of Catalyst.

         5. No Rights Granted. Nothing in this Agreement is intended to grant
any rights under any patent or copyright of either party, nor shall this
Agreement grant Recipient any rights in or to Catalyst's Confidential
Information, except the limited right to review such Confidential Information in
connection with the proposed Relationship between the parties.

         6. Term. The foregoing commitments of each party shall survive any
termination of the Relationship between the parties, and shall continue for a
period terminating on the later to occur of the date (i) five (5) years
following the date of this Agreement or (ii) three (3) years from the date on
which Confidential Information is last disclosed under this Agreement.

         7. Miscellaneous. This Agreement shall be binding upon and for the
benefit of the undersigned parties, their successors and assigns, provided that
Catalyst's Confidential Information may not be assigned without Catalyst's prior
written consent. Failure to enforce any provision of this Agreement by a party
shall not constitute a waiver of any term hereof by such party.

         8. Governing Law; Jurisdiction. This Agreement shall be governed by and
construed and enforced in accordance with the internal laws of the State of
California, and shall be binding upon the parties hereto in the United States
and worldwide. The federal and state courts within County of Santa Clara in the
State of California shall have exclusive jurisdiction to adjudicate any dispute
arising out of this Agreement.

         9. Remedies. Each party agrees that its obligations provided herein are
necessary and reasonable in order to protect Catalyst and its business, and each
party expressly agrees that monetary damages would be inadequate to compensate
Catalyst for any breach by Recipient of its covenants and agreements set forth
herein. Accordingly, each party agrees and acknowledges that any such violation
or threatened violation will cause irreparable injury to Catalyst and that, in
addition to any other remedies that may be available, in law, in equity or
otherwise, Catalyst shall be entitled to obtain injunctive relief against the
threatened breach of this Agreement or the continuation of any such breach by
Recipient, without the necessity of proving actual damages.

                                 August 6, 1998



Catalyst Semiconductor, Inc.
1250 Borregas Avenue
Sunnyvale, California
Attention:  Tom Gay

Dear Mr. Gay:

         Reference is hereby made to that certain Loan and Security Agreement,
dated June 19, 1997, by and between Catalyst Semiconductor, Inc., a Delaware
corporation ("Catalyst") and Coast Business Credit ("Coast"), (the "Agreement")
and that certain Loan and Security Agreement, CEFO Facility, dated June 19, 1997
between Catalyst and Coast (the "CEFO Agreement"). Initially capitalized terms
used in this forbearance letter which are not otherwise defined shall have the
meanings assigned to such terms in the Agreement and the CEFO Agreement, as
applicable.

         Catalyst has failed to comply with Section 6.1(a), 6.1(c), 6.1(f),
6.l(g) and 6.l(n) (Catalyst's Defaults under 6.1(a), 6.1(c), 6.1(f), 6.1(g) and
6.1(n) through June 30, 1998 are, the "Existing Defaults") of the Agreement and
the CEFO Agreement, in that Catalyst has failed to accurately report on the
Collateral, failed to file its 1OQ and 10K reports as required under Section
4.2, failed to promptly notify Coast in writing of changes to its officers and
directors as required under Section 4.5, and failed to adequately protect the
Collateral from material decreases in value to the point that Coast deems itself
insecure.

         The Existing Defaults constitute Events of Default under and as defined
in the Agreement and the CEFO Agreement. The occurrence of such Events of
Default entitles Coast, at its election and without demand, to immediately
terminate its obligations under the Agreement and the CEFO Agreement to make
Loans to Catalyst, or to declare the obligations to be due and payable, or both.

         Catalyst has requested that Coast forbear taking action on the Existing
Defaults. Coast is willing to and does hereby forbear taking action on the
Existing Defaults until September 30, 1998, provided that a non-refundable fee
of $33,750 which is fully earned up front and paid to Coast no later than August
5, 1998. Any Event of Default that is not an Existing Default shall not be
subject to this forbearance.

Tom Gay

         The forbearance set forth hereinabove shall be limited precisely as
written and shall not be deemed to (a) be a waiver or modification of any other
term or condition of the Agreement, the CEFO Agreement or any other loan
document or (b) prejudice any right or remedy which coast may now have or may
have in the future (except to the extent such right or remedy is based upon the
foregoing Existing Default) under or in connection with the Agreement, the CEFO
Agreement or any loan document.

         Please acknowledge your receipt of this forbearance letter and
acceptance of the foregoing terms and conditions by signing and dating the
enclosed counterpart of this forbearance letter where indicated below and
returning same to the undersigned as soon as possible.

                                        Very truly yours,


                                        COAST BUSINESS CREDIT
