ITEM 1.  BUSINESS

GENERAL

    Data Systems & Software Inc., through its subsidiaries and affiliates in the
United States and in Israel (collectively, the "Company"), (i) provides computer
consulting and development services to customers, (ii) has developed and is
currently marketing PHD-TM- - Professional Help Desk-TM-, an integrated software
suite for the "help desk" market, (iii) acts as an authorized direct seller,
value-added-reseller ("VAR") and integrator of computer hardware systems and
(iv) provides data communications and related products and services to utilities
and other customers.

    Through the end of 1996, the Company conducted its business through two
business segments: the Computer Segment and the Semiconductor Segment (conducted
through Tower Semiconductor Ltd. ("Tower")). Although the Company retains
effective control of Tower, due to changes in the Company's voting control in
Tower, the balance sheets as at December 31, 1996 and December 31, 1997 do not
include Tower balances. Commencing with 1997, the Company accounts for its
interest in Tower's results using the equity method, including its pro-rata
share of Tower's net income as equity income.

    The following table shows, for the years indicated, the dollar amount and
the percentage of the sales attributable to the different activities of the
Computer Segment:

   CONSULTING AND DEVELOPMENT SERVICES

    The Company provides computer software and systems consulting and
development services, primarily to high technology customers in Israel and the
United States. The Company's principal area of technological expertise is
state-of-the-art, embedded real-time software systems in a wide variety of
applications, including telecommunications, digital signal processing, image
processing and software testing and validation, radar, navigation, electronic
warfare, simulation and electro-optics.

    The Company provides consulting and development services to customers
primarily by furnishing software and systems engineers, programmers and
technicians who perform design and development activities, generally on the
customer's premises. In these engagements, the Company's personnel generally
work under the customer's direction, having no specific obligation for product
delivery, and the customer pays the Company on a time and materials basis for
the services provided. During 1995, 1996 and 1997, sales attributable to
services provided on a time and materials basis were $14.9 million, $12.2
million and $16.8 million, respectively, accounting for approximately 49%, 36%
and 42% of Computer Segment sales for such years, respectively.

    In addition to performing services on a time and materials basis, the
Company also undertakes work on a project basis with full responsibility for
delivering a specific software or hardware/software solution to a customer's
specifications or requirements. These projects generally are performed at fixed
prices and the profit margins on these projects are primarily determined by the
Company's success in controlling project costs. Profits derived from such
contracts may vary substantially as a result of various factors, including risk
of loss due to underestimating costs, difficulties with new technologies and
economic and other changes that may occur during the term of the contract.
During 1995, 1996 and 1997, sales from fixed price contracts were $2.3 million,
$2.7 million and $2.8 million, respectively, accounting for approximately 7%, of
Computer Segment revenues during these years.

The Company provides dedicated Internet access to business customers in greater
Cincinnati, Ohio. In addition, the Company provides web hosting for business
customers primarily in the United States and provides an international resume
database of experienced information systems professionals (known as placeum.com)
to professional recruiters on a subscription basis.

   HELP DESK SOFTWARE

    The Company develops and markets customer service and support solutions
catering to the help desk segment of the CIS market. A help desk is, typically,
a service center set up by the information services (IS) department of an
organization to answer questions and solve problems relating to computer
hardware, software, telecommunications systems, or any company-specific issues.
PHD Professional Help Desk solutions address the needs of customers operating
within a client/server environment, with users enjoying out-of-box, customizable
solutions that include call, asset and problem management, in addition to
Web-based support and remote analyst and end-user access.

    The Company's products are designed to allow help desk personnel to manage
incoming telephone calls, Web-based inquiries, or e-mail messages (call
management), resolve problems and capture knowledge (problem/knowledge
management), and manage personnel, equipment and other company resources (asset
management). PHD utilizes Experienced Based Reasoning-TM- (EBR-TM-), the
Company's proprietary problem resolution engine that automatically captures
customer data and creates a pool of shared knowledge about the nature of the
problems encountered and the solutions proposed. This effectively helps lessen
the problems associated with the help desk analyst turnover. EBR provides the
user with an organic growing body of knowledge from which to solve future
problems. This information can be made available to both help desk personnel and
end-users, facilitating self-diagnosis and problem resolution.

    PHD offers client/server solutions grounded in a Microsoft framework.
Supported platforms include Windows NT, Windows 95, Windows 3.X and Windows CE
(for use with portable devices such as PDAs and PIMs). PHD solutions incorporate
Microsoft's Visual Basic for Applications (VBA), serving as the Company's
universal API. The addition of VBA effectively extends the reach of the help
desk, allowing for unprecedented customization and integration with existing
software investments.

    PHD/X, built upon Microsoft's ActiveX technology, will allow application
programmers and developers to embed selected service and support PHD functions
directly into their products. The resulting applications will provide fully
integrated, robust and sophisticated help desk capabilities. The Company's first
ActiveX module, EBR/X, is presently shipping with the Professional Help Desk
suite. Additional modules are currently in development.

    Capitalizing on the success and popularity of Java, PHD recently introduced
PHDWeb, the first Sun Microsystems certified "100% Pure Java" help desk
platform. PHDWeb offers the full functionality of the traditional Professional
Help Desk package over the Internet.

    Through the end of 1997, the Company had invested approximately $7.9 million
on development, marketing and other costs associated with introduction of PHD.

Factors - Entry Into New Markets" and "-Capitalization of Software Development
Costs; Possibility of Future Writedowns" and "Item 7. Management's Discussion
and Analysis of Financial Condition and Results of Operations - General".

   COMPUTER HARDWARE AND VAR SALES

    The Company, through its Databit subsidiary, sells and services PC-based
computer hardware, software, data storage, client/server and networking
solutions. Databit is an authorized direct seller, value-added reseller and an
authorized service provider for equipment and software from such well-known
industry leaders as Compaq, IBM, Microsoft, Hewlett-Packard, Silicon Graphics,
Texas Instruments and Dell. Databit offers its customers a full range of systems
integration services, including design, implementation, hardware and software
selection and network cabling and installation, of local and wide area networks.
Databit provides maintenance and service to customers under extended service
agreements.

   DATA COMMUNICATION PRODUCTS AND SERVICES TO UTILITIES

    Since 1992, through the PowerCom division of DSI Israel, the Company has
been designing, developing and marketing two-way interactive communications
solutions which provide real-time remote automated meter reading ("AMR") and
data management capabilities to utilities, energy service companies and
industrial and commercial customers. PowerCom's electronic power supply
management ("EPSM") system uses existing power lines to transmit the electricity
consumption data of each meter to the utility's main computer. A comprehensive
software package controls the system's operations and facilitates functions such
as real-time load switching, peak demand control and detection of leakage and
illegal use of electrical power. Pilot testing in Argentina has been completed
and beta site testing is currently being conducted in Mexico, Venezuela and a
number of towns in Israel. Although no full scale system sales of EPSM have been
made to date, the Company is currently negotiating with utilities in several
countries regarding installation of a pilot system or on a trial basis. Through
December 31, 1997 the Company had invested approximately $5.4 million (net of
government and customer participation) on development and marketing of the EPSM,
including $4.6 million carried on the balance sheet as capitalized software
costs.

    In January 1998, the Company acquired certain assets and licensed
intellectual property from Lucent Technologies, Inc. This technology will be
used by the Company's recently formed Comverge Technologies subsidiary which
will market the Customer Connection for Utilities (CCU) to customers in the U.S.
The CCU has been previously deployed at Public Service Electric and Gas using a
two-way cable TV system and at Duke Power using a cellular digital packet data
(CDPD) network. Five employees involved in developing the CCU have joined the
Comverge team.

         The Company's communication systems are designed to allow customers to
compete more effectively by enabling them to reduce costs, defer capital
spending, increase sales revenues and improve service quality and scope. The
Company plans to broaden its target markets beyond utility companies to include
energy service providers, cooperatives, aggregators, municipals, and
telecommunications network service providers, as well as rekindle and expand
former strategic alliances and customer relationships. The Company intends to
expand its systems capabilities to include, in addition to its powerline
communications (PLC) technology, plain old telephone (POTS), personal
communication services (PCS) and Internet transport using its standards-based
open architecture.

         The Company believes that its prior experience in the development,
manufacture, marketing and sales of energy management systems internationally,
together with the recently acquired assets and licensed technology, will permit
the Company to take advantage of market and product synergies, expand its U.S.
market and exploit the data communications and energy management needs of the
global utilities markets which are rapidly undergoing deregulation. See "Item 1.
Business - Factors Which May Affect Future Results - General Factors - Entry
Into New Markets" and "-Capitalization of Software Development and Costs;
Possibility of Future Writedowns" and "Item 7. Management's Discussion and

MULTIMEDIA ENTERTAINMENT

         Since 1996, the Company has engaged in the development and marketing of
interactive, multimedia entertainment products under the Cybrcard-TM- name,
including 1996 NFL-R- Cybrcards, 1997 Major League Baseball-R- Cybrcards and
1997 NFL-R-Cybrcards. These products have generated only limited sales to date.
Due to the high costs associated with the marketing of consumer multimedia
products, the Company does not currently intend to develop and market additional
multimedia entertainment products in 1998. The Company, however, is actively
pursuing projects in the multimedia area in which the Company would have
responsibility for design and development of products which would be marketed
and sold by others. It is contemplated that in any such projects the cost of
development would be covered by the party with responsibility for the marketing
of the product. The Company would receive a combination of a fixed development
fee and/or royalties from the sale of products.

         As of December 31, 1997 the Company had invested approximately $6
million in product development and marketing and administrative costs in
connection with its establishment of CybrCard and its product lines, all of
which was expensed. 

CUSTOMERS AND MARKETS

    The Company's Computer Segment commenced operations in Israel in 1986 and
Israel historically was the primary area of its operations. Due primarily to
significant growth in the Computer Segment's United States subsidiaries, the
percentage of revenues from activities of the United States subsidiaries
increased from 51% in 1995 to 61% in 1996 and 64% in 1997.

    The Company commenced its operations in Israel by providing consulting
services to Israel Aircraft Industries Ltd. ("IAI"), which is wholly-owned by
the government of the State of Israel. IAI has been, and continues to be, the
Computer Segment's largest consulting customer. However, as the Company has
expanded its revenue base, and sales to IAI have decreased, the percentage of
its sales attributable to IAI has decreased. The percentage of the Company's
Computer Segment sales attributable to IAI in 1995, 1996 and 1997 was 16%, 8%
and 6%, respectively.

    The Company's Computer Hardware and VAR sales commenced in 1992, accounting
for 28% of Computer Segment sales in 1995, increasing by almost 80% to 38% of
these sales in 1997. The Company's two largest hardware customers (a major New
York medical center and a large national law firm) accounted for approximately
10% and 5% and 11% and 12% of Computer Segment sales in 1996 and 1997,
respectively.

    The Company's customers include major high technology companies, Fortune 500
companies and other leading industrial and service companies, in Israel and the
United States.

   BACKLOG

    The total backlog of work to be completed in the Company's Computer Segment
was approximately $1.7 million as of January 1, 1998, compared to $4.3 million
as of January 1, 1997. The Company estimates that virtually all of the backlog
will be performed in 1998.

    Due to the generally short-term nature of orders received in the Computer
Segment, purchase orders or requisitions from customers requesting services on a
time and materials basis generally are cancelable on a minimum of 30 days
advance notice. Fixed price projects are often subject to termination for
convenience without substantial penalty and, accordingly, there can be no
assurances as to the actual sales to be generated from these contracts. In light
of the above, the Company does not consider backlog to be a meaningful measure
of operations in its Computer Segment.

   COMPETITION

    In its computer consulting and development services business, the Company
faces competition from numerous other competitors, both large and small,
operating in the Israeli and United States markets, some with substantially
greater financial and marketing resources. The Company believes that its wide
range of experience and long-term relationships with large corporations in the
United States and Israel enhance the Company's position with respect to
obtaining future business. For a discussion of factors relating to competition
in the other activities comprising the Company's Computer Segment, see "Item 1.
Business -Factors Which May Affect Future Results -General Factors -Competition.

   PROPRIETARY RIGHTS

    Certain products that the Company has developed and is developing
incorporate or are derived from intellectual property owned by third parties. A
license from, the consent of, or a joint development and marketing agreement
with, such third parties may be required in order to continue to develop and
market such products and there can be no assurance that any such arrangements
can be made on commercially reasonable terms.

    In its product development activities, the Company relies on a combination
of nondisclosure agreements and technical measures to establish and protect its
proprietary rights, if any, in its products. The Company believes that, as a
result of the rapid pace of technological change in the software and real-time
system industries, legal protection for its products, if any, will be less
significant to the Company's prospects than the knowledge, ability and expertise
of the Company's management and technical personnel.

    In cases where the Company performs services on a time and materials basis,
the intellectual property rights resulting from these services are owned by the
Company's customer.

    For further discussion of issues relating to proprietary rights to the
operation of the Company's Computer Segment, see "Item 1. Business - Factors
Which May Affect Future Results - General Factors - Dependence on Intellectual
Property of Third Parties".

SEMICONDUCTOR MANUFACTURING

   INTRODUCTION

    Tower is an independent "foundry" manufacturer of semiconductor integrated
circuits ("ICs") on silicon wafers, as well as a provider of design and turn-key
services. As a foundry, Tower manufactures wafers using its advanced production
capability and the proprietary IC designs of its customers. ICs manufactured by
Tower are incorporated into a wide range of products in diverse markets,
including computer and office equipment, communication products and consumer
electronics.

    Semiconductors are the foundation of modern electronic equipment and
systems, constituting critical components for a wide range of products,
including computers, office equipment, communication equipment and defense,
aerospace, transportation and consumer electronics. A semiconductor may be
either a discrete device, such as an individual transistor, or an IC in which a
number of transistors and other elements are combined to form a more complex
circuit. A wide variety of semiconductor products currently are in use, ranging
from commodity products (such as DRAM, SRAM and other commodity memories) to
more differentiated products (such as microprocessors, ASICs and numerous
digital, analog and mixed-signal ICs).

   SERVICES

    Tower manufactures ICs on silicon wafers based upon proprietary designs
provided by its customers. Tower specializes in the manufacture of
differentiated IC products, which generally require greater process flexibility
and customization than commodity products. The end-product manufactured by Tower
is a silicon wafer containing multiple ICs.

    In 1997, Tower continued to implement its strategy to develop and provide
customers with new specialized proprietary process technologies and value-added
services, particularly in certain niche markets, such as nonvolatile memories
("NVMs"). Together with Wafer Scale Integration, Inc., of Fremont, California,
("WSI"), a developer of peripheral system devices containing advanced NVM
modules, Tower developed an advanced embedded erasable and programmable
read-only memory ("EPROM") process based on WSI's proprietary technology. The
EPROM process has been qualified for production and initial production orders
have been received.

    The Company has established a design team to offer specialized NVM design
services, including NVM modules, mixed-signal cells and design library support,
to potential customers and independent design centers seeking to utilize Tower's
NVM process technologies. Since May 1997, the design team has conducted 
these activities from Tower's new Design Center in Nethanya, Israel.

    In 1997 Tower also entered an agreement with Saifun Semiconductor Ltd. for
use of its breakthrough Flash technology and for the development of a
specialized Flash process. This process is especially suitable for embedding
large NVM arrays in "system-on-a-chip" products and has generated significant
customer interest. Throughout 1998, Tower anticipates continued investment in
the development of Flash features such as large memory arrays, endurance
verification and other support parameters. The Flash memory process is scheduled
to be released to manufacturing by the end of 1998, although there can be no
assurance of this.

   CUSTOMERS AND MARKETS

    At the time of its organization, Tower's only customer was National
Semiconductor Corporation. While Tower has since succeeded in adding new
customers, Tower remains dependent on a small number of customers for virtually
all of its business. In 1997, over 70% of Tower's sales were attributable to two
large customers, National and Motorola. In January, 1998, Tower entered into a
new purchase agreement with National, extending the foundry relationship with
National until at least February 2000.

    Following a market downturn in 1996, growth for the foundry industry was
flat primarily as a result of massive price reductions, offset by continued
increases in wafer consumption in the end markets. Despite the flat market, the
Company, which had operated below capacity for much of 1996, was able to
increase its sales by more than 28% over 1996 and operate at a profit. However,
the situation in the marketplace remains uncertain and there is no assurance
that Tower's facility will operate at the level necessary for profitability. In
addition, Tower continues to see downward pressure on prices from both current
and potential new customers. See "Item 1. Business - Factors Which May Affect
Future Results - Factors Related to Tower - Reliance on Principal Customers;
Need to Expand Custome Base" and "Item 7. Management's Discussion and Analysis
of Financial Condition and Results of Operations - General."

    During 1997, Tower manufactured over 200 sophisticated semiconductor
products that are used by its customers (or end users) in a wide variety of
applications. These applications include personal computer products and
peripherals (such as microprocessors, local area networks and super I/O
devices), communications products (such as pagers), office automation products
(such as facsimile machines, answering machines and advanced printers), cellular
products (such as cellular telephones) and consumer products (such as
televisions and multimedia products). Tower estimates that five products
accounted for approximately 70% of sales. The number of products which Tower
manufactures in 1998 and in future periods will be determined by customer
orders.

   PROCESS TECHNOLOGY

    Tower's manufacturing process currently uses the following CMOS
(complementary metal oxide silicon) technologies: 1.0 micron double-level metal;
0.8 micron double-level metal; 0.8 micron triple-level metal; 0.6 micron
double-level metal; and 0.6 micron triple-level metal. In 1997, 0.5 micron
processes were qualified and began production in small quantities.

    The semiconductor industry is characterized by rapid changes in both product
and manufacturing process technology. As a result, Tower's profitability will
depend on its ability to successfully develop and introduce to production
advanced process technologies which meet its customers' needs. Tower is
currently working on the development of a 0.5 micron double poly process for
mixed signal applications, as well as characterization of a 0.5 micron process
for CMOS image sensor applications. A 0.35 micron process is expected to be
qualified for full production later in 1998, although there can be no assurance
of this.

    The development and introduction to production of advanced technologies is a
complex process, the success of which is dependent on many factors, some of
which may be beyond Tower's control. Tower has in the past experienced
unforeseen delays in the development and introduction of new processes. Tower
can, therefore, not predict when or if the development and introduction to
production of these new processes will be successfully completed. The failure by
Tower to develop and introduce new process technologies successfully and in a
timely manner would have a material adverse effect on Tower's business and
financial condition of the Company. See "Item 1. Description of Business -
Factors That May Influence Future Results - Factors Related to Tower - Need to
Advance Process Technology".

   MANUFACTURING FACILITY

    Due to the sensitivity and complexity of the semiconductor manufacturing
process, a semiconductor manufacturing facility requires a special clean room in
which most of the manufacturing functions are performed. Tower's manufacturing
facility includes an approximately 51,500 square foot clean room. Tower has
obtained ISO 9002 certification (a certification with respect to business
process quality standards) for its manufacturing operations.

    At the time of its organization in 1993, Tower's facility had a capacity of
5,000 wafer starts per month, using 1.25 and 1.0 micron processes. Since that
time Tower has increased its capacity to approximately 17,000 wafer starts per
month at the current product mix utilizing 1.0, 0.8, 0.6 and 0.5 micron
processes. This increase in capacity has been achieved through the addition of
equipment, improvement in equipment utilization, the reconfiguration and
expansion of its existing clean room area, and the construction of an additional
clean room area.

                                        5
<PAGE>

    Tower does not currently intend to significantly increase the overall
capacity of its facility. Tower intends, however, to continue to make
significant expenditures during 1998 to fund its process technology advancement
program and to purchase equipment to increase Tower's capacity to manufacture
wafers using advanced processes, including those currently under development by
Tower. See "Item 1. Description of Business - Semiconductor Segment - Process
Technology".

   COMPETITION

    The semiconductor foundry industry is highly competitive. Tower competes
with other dedicated foundries and with integrated semiconductor companies and
end-product manufacturers that produce ICs for their own use and/or allocate a
portion of their manufacturing capacity to foundry operations. Particularly
during periods of market downturn, Tower may face increased competition from its
customers' internal manufacturing capacity and from other semiconductor
manufacturers who have underutilized capacity.

    Many of Tower's competitors have more advanced technological capabilities, a
more diverse and established customer base, and greater financial, marketing,
distribution and other resources than Tower. In addition, some competitors of
Tower may have lower labor costs. Tower competes primarily by seeking to offer
customers competitive pricing and a high level of service and process
customization.

   PROPRIETARY RIGHTS

    Tower uses internally developed process technologies and process
technologies licensed from customers. The 1.0 micron process used by Tower and
elements of the 0.8 process used by Tower are licensed from customers under
royalty-free licenses. The 0.6 micron process currently used by Tower and
specialized 0.6 micron embedded memory process currently being introduced to
production were internally developed. Elements of the 0.5 micron processes and
0.35 micron process currently under development will be used under
royalty-bearing licenses from third parties.

Investments

   MOFET VENTURE CAPITAL FUND

    The Company, together with other investors, established Mofet Israel
Technology Fund ("Mofet"), an Israeli public investment company formed for the
purpose of investing in the securities of high technology companies and projects
in Israel. Through two public offerings of its shares, options and convertible
debentures on the Tel Aviv Stock Exchange, and subsequent exercise of options,
Mofet has raised aggregate net proceeds of approximately $23.2 million. As of
December 31, 1997, the Company owned approximately 4% of the equity of Mofet.
The Company accounts for its investments in Mofet on the cost method.

    Mofet is managed by Mofet Risk Capital Fund Management (1992) Ltd. ("Mofet
Management") pursuant to a management agreement expiring January 2000. The
current shareholders of Mofet Management are DSI (50%), F.I.B.I. Holdings
Company Ltd., a holding company controlled by the Safra family which controls
the First International Bank of Israel Ltd. (25%), and Menorah Insurance Company
Ltd., one of Israel's largest insurance companies (25%). Mofet has agreed to pay
Mofet Management a management fee equal to 4% per annum of the amounts invested
in the Fund (excluding profits). The Company accounts for its investment in
Mofet Management on the equity method.

MOBILE INFORMATION SYSTEMS LTD.

    In March 1994, the Company acquired a 50% interest in Mobile Information
Systems Ltd. ("MIS"), a joint venture of DSI and Geotek Communications, Inc.
("Geotek"). The Company accounted for its investment in MIS on the equity
method. In 1996 the Company sold its shares in MIS to Geotek in exchange for a
$2 million unsecured note which bears annual interest of 8.25%, payable July 1,
1998. The Company thereby recorded a gain in 1996 of approximately $1.7 million
in connection with the sale. In February 1998, the Company signed an agreement
with Geotek, modifying the note to permit its conversion into shares of Geotek
Common Stock. Geotek has filed a registration statement registering the resale
by the Company of these shares. Upon effectiveness of the registration
statement, the Company will be free to sell the shares in the public market.

EMPLOYEES

    At December 31, 1997, the Company employed a total of 349 people, including
262 persons in engineering and technical support (approximately one-half with
advanced degrees in computer and electronic engineering), 30 in marketing and
sales, and 55 in management, administration and finance. At December 31, 1997,
Tower had a total of 656 employees.

    The Company considers its relationship with its employees to be
satisfactory.

    There are no collective bargaining agreements between the Company and any of
its employees. However, certain provisions of the collective bargaining
agreements between the Histadrut (General Federation of Labor in Israel) and the
Coordination Bureau of Economic Organizations (including the Industrialists
Association) are applicable to the Company's Israeli employees by order of the
Israeli Ministry of Labor. These provisions concern mainly the length of the
work day, minimum daily wages, contributions to a pension fund, insurance for
work-related accidents, procedures for dismissing employees, determination of
severance pay and other conditions of employment. The Company generally provides
its Israeli employees with benefits and working conditions beyond the required
minimums.

    Israeli law generally requires severance pay upon the retirement or death of
an employee or termination of employment without due cause. Furthermore, Israeli
employees and employers are required to pay specified amounts to the National
Insurance Institute, which is similar to the United States Social Security
Administration. The payments to the National Insurance Institute include health
tax and are approximately 17% of wages (up to a specified amount), of which the
employee contributes approximately 60% and the employer approximately 40%.

FACTORS WHICH MAY AFFECT FUTURE RESULTS

    The Company may from time to time issue certain statements, either in
writing or orally, that contain or may contain forward-looking information.
There can be no assurance, however, that actual results will not differ
materially from the Company's expectations, statements or projections. Factors
that could cause actual results to differ from the Company's expectations,
statements or projections include the risks and uncertainties relating to the
Company's business described below.

   GENERAL FACTORS

    ENTRY INTO NEW MARKETS. The Company has recently devoted substantial
resources to ventures to design and develop software products. The Company
believes that the markets for these products provide an opportunity to generate
substantially greater revenues and profit margins than its traditional services
markets. However, the Company has had relatively limited experience with
marketing and distribution of such products and there can be no assurance that
the Company will be able to develop the marketing expertise and relationships
necessary to identify and capitalize on opportunities in these product areas.
The limited operating histories of the Company's new product ventures make
prediction of their results and prospects difficult.


                                        7
<PAGE>

    CAPITALIZATION OF SOFTWARE DEVELOPMENT COSTS; POSSIBILITY OF FUTURE
WRITEDOWNS. The Company generally capitalizes the costs of new software product
development and amortizes these costs over the useful life of the product. If
the Company is not able to complete development or is unsuccessful in marketing
any of its software products, the Company may be required to writedown any
capitalized development costs related to such products. As of December 31, 1997,
the Company had unamortized capitalized software development costs of
approximately $4.6 million and additional investments in development costs may
be necessary to continue existing product development projects. In the past, the
Company has taken significant writedowns of software development costs and there
can be no assurances that additional writedowns will not be required in the
future. The writedown of any substantial amounts of such capitalized costs could
have a material adverse impact on the results of the Company.

    MINORITY INTERESTS IN OPERATING SUBSIDIARIES. The Company has a number of
subsidiaries that are not wholly owned. Cash of subsidiaries that are not wholly
owned is generally not available for use by the Company or other subsidiaries
except to the extent paid to the Company as reimbursement for general overhead,
as management fees or as dividends. Dividends from the Company's Israeli
subsidiaries are subject to a withholding tax of 15% to 25%.

    COMPETITION. In its computer consulting and development services business,
the Company faces competition from numerous other competitors, both large and
small, operating in the Israeli and United States markets, some with
substantially greater financial and marketing resources.

    In the help desk market, the Company faces competition from a variety of
companies with greater experience in the marketplace and greater resources
available for product development, sales and marketing and product support.
These competitors include (i) companies that target enterprise-wide information
systems, (ii) companies with specific help-desk applications, (iii) professional
systems integration and services companies that design and implement custom
systems, (iv) large information systems providers and (v) the internal
information systems departments of potential customers. While the Company
believes that PHD has certain product and price advantages over its competition,
it may be difficult to educate its potential customers of the advantages of PHD
in light of the broad range of competing solutions.

    The market for personal computer and related peripheral hardware sales in
which the Company's Databit subsidiary operates is characterized by severe
competition in price-performance, breadth of product line, financing
capabilities, technical expertise, service and overall reputation. Trends have
been for ongoing price reductions by manufacturers to end-users, thereby
reducing profit margins for distributors and value added resellers such as
Databit. Competitors include manufacturers, other VAR's, large equipment
aggregators (some of whom sell to the Company) and systems integrators. Many of
the Company's competitors have longer operating histories, greater financial
resources and buying power and larger installed bases of customers. The Company
feels that it competes primarily on the basis of its responsiveness and
technical expertise in evaluating customer needs and tailoring specific
solutions to those needs, as well as price.

    The global market for automatic meter reading ("AMR") products is highly
competitive. The Company believes the principal competitive factors affecting
its sales of communication systems for AMR networks are its products'
technological capabilities, design features and functionality, price, quality of
service, reliability, ease of installation and scalability. New technological
developments, technical expertise, vendor reputation and technical support also
affect the competitiveness of the Company's products in the AMR market. While
the Company believes it competes favorably in these areas, many of its
competitors currently have (or may have) substantially greater financial,
marketing, technical or manufacturing resources and name recognition than the
Company. There can therefore be no assurance that the Company will be able to
successfully compete against current or future competitors in this market.

     The emerging market for utility network automation systems and the
potential market for other applications accessible once a common infrastructure
is in place, have led electronics, communication and utility product companies
to initiate development of various data communication systems. Some of these
systems currently compete, and others may in the future compete, with the


                                        8
<PAGE>

Company's communication systems. Many companies from diverse industries are
seeking solutions for the transmission of data over traditional communication
media such as radio, as well as more recently developed media such as cellular
networks. Utility companies are testing communication products from various
suppliers for numerous applications and no industry standard has been broadly
adopted. The Company's systems represent only some possible solutions for
automated meter reading.

    DEPENDENCE ON INTELLECTUAL PROPERTY OF THIRD PARTIES.  Certain of the
Company's product development efforts are dependent upon intellectual property
owned by third parties. For example, some of the Company's data communication
products utilize intellectual property licensed from Lucent Technologies. While
the Company believes it is in continuing compliance with these licensing
agreements and that the licensing agreements adequately protect the Company's
rights to integrate such intellectual property into its products, failure to
maintain such licenses could have a material adverse effect on the business and
prospects of the Company.

    RAPID TECHNOLOGICAL CHANGE; NEED FOR CONTINUED PRODUCT DEVELOPMENT. The
market for the Company's PHD product is characterized by rapid technological
change, evolving computer hardware and software standards, frequent new product
introductions and continuing customer demands for expanded features and
functions. Accordingly, it will be necessary for the Company to continue to
invest in product development to ensure that such products continue to evolve
and remain competitive. There can be no assurance that the Company will have the
resources to invest in such product development or that such product development
efforts will be successful.

    The rapid technological change in digital communication systems, especially
in the U.S., will necessitate the adaptation of the Company's data communication
systems for utilities to new communication technologies. Accordingly, it will be
necessary for the Company to develop full system compatibility with telephone,
cable television, CDPD and various wireless distribution networks. There can be
no assurance that the Company will have the resources to invest in the continued
product development required to keep pace with the changing technologies or that
such product development efforts will be successful.

    OPERATIONS IN ISRAEL. A substantial portion of the Company's operations are
conducted in the State of Israel and, consequently, the Company is directly
affected by economic, political and military conditions in Israel. Accordingly,
any major hostilities involving Israel or the curtailment of trade between
Israel and its current trading partners could have a material adverse effect on
the Company's business and financial condition. In addition, certain
subsidiaries of the Company receive grants and tax benefits from, and
participate in, various programs sponsored by the government of Israel. There
can be no assurance that such grants and tax benefits will be continued in the
future at their current levels or at all. The termination or reduction of
certain grants, programs and tax benefits could have a material adverse effect
on the Company's business and financial condition.

    IMPACT OF INFLATION AND CURRENCY FLUCTUATIONS. Substantially all of the
Company's sales are made in dollars or in New Israeli Shekels ("NIS") linked to
the dollar. In 1997, approximately 50% of Tower's expenses were in dollars or
dollar-linked NIS and virtually all remaining expenses were in NIS. The dollar
cost of the Company's operations in Israel is influenced by the extent to which
any inflation in Israel is not offset (or is offset on a lagging basis) by the
devaluation of the NIS in relation to the dollar. There can be no assurance that
the Company will not be materially adversely affected in the future if inflation
in Israel exceeds the devaluation of the NIS against the dollar or if the timing
of such devaluation lags behind increases in inflation in Israel.

    As of December 31, 1997, the net amount of the Company's monetary assets
that were not denominated in dollars or in NIS linked to the dollar was not
material. In the event that in the future the Company has material net monetary
assets that are not denominated in dollar-linked NIS, such net assets would be
subject to the risk of currency fluctuations.

   FACTORS RELATED TO TOWER

    DEPENDENCE ON PRINCIPAL CUSTOMERS; NEED TO EXPAND CUSTOMER BASE. Tower
currently has a limited number of customers and is dependent on two principal
customers. If one of these principal customers were to reduce its orders, and
Tower were to be unsuccessful in selling to new or existing customers the
capacity that becomes available as a result thereof, such event would have a
material adverse effect on Tower's business and financial condition. Since the
end of 1997, Tower has been operating significantly below capacity. Tower is
making efforts to attract new customers to utilize all or a portion of its
unused capacity. Tower is currently engaged in discussions with several
potential new customers. The process of attracting new customers includes
extensive exchange of product and process information between Tower and
potential customers, including the running of test wafers and prototypes. There
is therefore no assurance that Tower will be able to attract additional business
from new customers in the near future, if at all.

    RISK OF OPERATING BELOW FULL CAPACITY. Fixed costs represent a substantial
portion of the total operating costs of a semiconductor manufacturing operation.
As a result, any failure by Tower to operate at or near full capacity, whether
due to mechanical failure, lack of orders, fire or natural disaster, or
otherwise, could result in losses or diminished profitability.

    NEED TO ADVANCE PROCESS TECHNOLOGY. The semiconductor industry is
characterized by rapid changes in both product and manufacturing process
technology. As a result, Tower's profitability will depend on its ability to
successfully develop and introduce to production advanced process technologies
which meet its customers' needs. Tower is currently working on the development
of a number of advanced processes.

    The development and introduction to production of advanced technologies is a
complex process, the success of which is dependent on many factors, some of
which may be beyond Tower's control. Tower has in the past experienced
unforeseen delays in the development and introduction of new processes.
Therefore, Tower cannot predict when or if the development and introduction to
production of these new processes will be successfully completed. The failure by
Tower to develop and introduce new process technologies successfully and in a
timely manner would have a material adverse effect on the Company's earnings and
financial condition.

    RISK OF SEMICONDUCTOR PROCESS YIELD PROBLEMS. The process technology for the
manufacture of semiconductor products is highly complex and sensitive to dust
and other contaminants. Minor impurities or difficulties in the production
process or defects in the masks used to manufacture a particular device can
cause a percentage of the wafers to be rejected or individual ICs or "die" on
specific wafers to be non-functional, which in each case negatively affects
manufacturing yields. Although Tower has implemented manufacturing control
procedures, tests its products at various stages in the manufacturing process
and conducts numerous quality-control inspections throughout the entire
production process, Tower in the past has experienced lower than expected
production yields, which have delayed product shipments and reduced profits.
There can be no assurance that Tower will not experience lower than anticipated
production yields in the future, which, if not cured in a timely manner, could
have a material adverse effect on the Company's business and financial
condition.

    CYCLICAL NATURE OF THE SEMICONDUCTOR MARKET. The semiconductor industry
historically has been characterized by wide fluctuations in product supply and
demand.  From time to time, the industry has experienced significant downturns
characterized by diminished product demand, production over-capacity and
accelerated erosion of the average selling prices of semiconductor products.  In
some cases, these downturns have lasted for more than a year. No assurance can
be given that Tower's business will not be adversely affected in the future by
cyclical conditions in the semiconductor industry.

    PROCUREMENT AND SOURCING.  Tower's manufacturing processes use many raw
materials, including silicon wafers, chemicals, gases and various metals.  These
raw materials generally are available from several suppliers and Tower is not


                                       10
<PAGE>

dependent upon any single source of supply, although, in some instances, Tower
elects to purchase certain raw materials from a single source. In those
instances, Tower generally identifies and qualifies alternative sources of
supply. Although supplies for raw materials used by Tower currently are
adequate, shortages could occur in various critical materials due to
interruption of supply or increased industry demand. Any such shortages could
result in production delays which could have a material adverse effect on
Tower's business and financial condition.

    In connection with implementing its technology advancement plans, Tower
expects to continue to make significant purchases of equipment required for
semiconductor manufacturing. Some of this equipment is available from only a
single vendor or a limited number of vendors and/or is manufactured in
relatively limited quantities. In addition, certain equipment has only recently
been developed. Delays in delivery and shortages in supply of such equipment, as
well as failures of such equipment to operate in accordance with Tower's
expectations, could result in higher costs and production delays and delay
implementation of Tower's technology and advancement plans. Any such delays,
shortages or failures could have a material adverse effect on Tower.

    RISKS RELATING TO ISRAELI GOVERNMENT PROGRAMS. The Investment Law for the
Encouragement of Capital Investments, 1959 (the "Investment Law") provides that
capital investments in certain production facilities (or other eligible
facilities) may, upon application to The Investment Center of the Ministry of
Industry and Trade of the State of Israel ("The Investment Center"), be
designated as an "Approved Enterprise". Virtually all of Tower's existing
facilities and programs, including Tower's current $240 million investment
program and the $93.4 million investment program which was substantially
completed in 1995, have been granted Approved Enterprise status under the
Investment Law. To be eligible for grants and tax benefits, Tower must continue
to meet certain conditions, including making certain specified investments in
fixed assets. The certificate of approval related to Tower's current Approved
Enterprise program requires, among other things, that all investments under the
program be completed by the end of 1998. Should Tower fail to meet such
conditions in the future, it could be required to refund grants or tax benefits
already received (together with interest and certain inflation adjustments).
There can be no assurance that such grants and tax benefits will be continued in
the future at their current levels or at all.

    DEPENDENCE ON SENIOR MANAGEMENT AND KEY PERSONNEL.  Tower is highly
dependent upon the members of its senior management team, many of whom have been
working at the facility since National commenced the construction of the
facility in 1984. The loss of the services of any member of senior management
could have a material adverse effect on Tower's business and financial
condition. Tower does not maintain key-man life insurance with respect to
members of senior management.

    Tower also is dependent to a substantial degree upon its skilled
professional and technical personnel and will be required to increase
significantly the number of these employees in the future in order to implement
successfully its plans for the future. There is considerable competition for the
services of qualified personnel in the semiconductor industry, particularly in
Israel, and, consequently, there can be no assurance that Tower will be able
either to retain its present personnel or to attract additional qualified
personnel as and when needed. In addition, Tower may be required to increase
employee compensation levels in order to retain its existing employees and
attract and retain the additional personnel that it expects to require.

    COMPETITION. The semiconductor foundry industry is highly competitive. Tower
competes with other dedicated foundries and with integrated semiconductor and
end-product manufacturers that produce ICs for their own use and/or allocate a
portion of their manufacturing capacity to foundry operations. Many of Tower's
competitors have more advanced technological capabilities, a more diverse and
established customer base, and greater financial, marketing, distribution and
other resources than Tower. In addition, some of Tower's competitors may have
lower labor costs.

    POSSIBLE SHORTAGES OF RAW MATERIALS AND EQUIPMENT. Although supplies for raw
materials and equipment used by Tower currently are adequate, shortages could
occur in the future in various critical materials and equipment due to
interruption of supply or increased industry demand. Any such shortages could
result in higher costs, production delays or delays in Tower's expansion, any of
which could have a material adverse effect on Tower's business and financial
condition.

     ENVIRONMENTAL MATTERS. Tower is subject to a variety of governmental
regulations related to the use, discharge and disposal of toxic, volatile or
otherwise hazardous materials used in its manufacturing process. Any failure by
Tower to use, discharge or dispose of hazardous materials appropriately could
subject it to substantial liability or could require it to suspend or adversely
modify its manufacturing operations. In addition, Tower could be liable for
remedial measures if its properties are found to be contaminated even if Tower
is not responsible for such contamination, although Tower's risk in this regard
is reduced by an indemnity from National for violations of environmental
regulations that occurred prior to Tower's acquisition of the facility.


                                       11

ITEM 2.  PROPERTIES

    The Company's corporate headquarters (as well as the principal office for
its United States operations) are located in Mahwah, New Jersey in approximately
5,000 square feet of office space, under a lease which expires in September
2000. The rent for these premises currently is $74,000 per annum. The Company
also rents offices in New York City of approximately 3,500 square feet, under a
lease which expires in August 2000, at a current rent of $75,000 per annum, and
of approximately 9,700 square feet in Stamford, Connecticut, at an annual rent
of $96,000.

    DSI's facilities in Israel are located in Givat Shmuel in the Tel Aviv area
in approximately 23,900 square feet of office space, under a lease which expires
in April 2000. The annual rent is currently approximately $326,000.

    Tower's offices, engineering and manufacturing operations are located in a
building complex situated on 13 acres in an industrial park in Migdal Haemek,
Israel. The buildings comprise approximately 180,000 square feet of space and
include clean room facilities of approximately 51,700 square feet. These
premises currently are occupied under a long-term capital lease from the Israel
Lands Authority which expires in 2032. The lease rights under this lease were
assigned to Tower as part of its acquisition of the facility and the value
attributed to the capitalized lease is being amortized by Tower over the life of
the lease. Tower has no obligation for lease payments related to this lease
through the year 2032.

ITEM 3.   LEGAL PROCEEDINGS

    The Company is a plaintiff in an action in the United States District Court
for the District of New Jersey against a former officer who resigned in April
1995, alleging destruction and misappropriation of property and data owned by
the Company. The employee has filed a counterclaim against the Company, alleging
breach by the Company of its employment and resignation agreements with the
employee and seeking compensatory damages of $750,000 and punitive damages of
$25 million. The Company is pursuing its claims against the employee and is
vigorously defending against his counterclaims. The Company accrued the full
amount of severance payable under the resignation agreement at the time of his
resignation. The Company believes it is unlikely to incur additional material
liability in connection with the counterclaim.

    Between June and September 1996, several suits were filed in the United
States on behalf of a purported class of Tower's shareholders against Tower, its
Co-Chief Executive Officers, its Chairman of the Board of Directors, and DSSI.
The complaints seek to certify a class of all persons who purchased or otherwise
acquired Tower's ordinary shares between May 25, 1995 and June 10, 1996. The
actions have been consolidated in the United States District Court for the
District of New Jersey. The consolidated complaint filed in the actions alleges
on behalf of the class that the defendants made misstatements and omissions
regarding (i) the relationship between Tower and a major customer and (ii)
Tower's process development efforts in connection therewith, in violation of
certain U.S. Federal securities laws. Tower has indemnified the defendants, up
to the limits permitted by the Israeli Companies Ordinance, from any liability
arising out of the actions. Tower maintains insurance policies, that, under
certain conditions, cover actions of this type up to an aggregate amount of $20
million. The Company is unable to determine at this time with any certainty the
ultimate outcome of this matter or its effect if any, on the Company's financial
condition, operating results and business. However, the Company believes it has
meritorious defenses and is defending the actions vigorously.

    The Company is not involved in any other legal proceedings that management
believes, individually or in the aggregate, will have a material adverse effect
on the Company.

ITEM 6.   SELECTED FINANCIAL DATA

    The following selected statement of operations data for the year ended
December 31, 1997 and balance sheet data as of December 31, 1997 have been
derived from the financial statements of the Company included elsewhere in this
Annual Report which have been audited by Deloitte & Touche LLP (a member of
Deloitte Touche Tohmatsu International), independent auditors. The following
selected statement of operations data for the years ended December 31, 1995 and
1996 and balance sheet data as of December 31, 1996 have been derived from the
financial statements of the Company appearing elsewhere in this Annual Report
which have been audited by Igal Brightman & Co. (a member of Deloitte Touche
Tohmatsu International), independent auditors. The selected statements of
operations data for the years ended December 31, 1993 and 1994 and balance sheet
data as of December 31, 1993, 1994 and 1995 are derived from audited financial
statements not included herein.

    This data is qualified in its entirety by reference to, and should be read
in conjunction with, the Company's Consolidated Financial Statements (including
the notes thereto) and "Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operations".

    The statement of operations data for the year ended December 31, 1993
includes Tower's operations for the ten months commencing March 1, 1993 and
therefore may not be comparable with statement of operations data for subsequent
periods. The balance sheet data as of December 31, 1996 and 1997 and the
statement of operations data for the year ended December 31, 1997 reflect the
Company's interest in Tower as an investment on the equity method, not otherwise
including Tower's balances or results of operations. Such data may therefore not
be directly comparable with that presented for prior periods.

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

General

     The following discussion includes statements that are forward-looking in
nature.  Whether such statements ultimately prove to be accurate depends upon a
variety of factors that may affect the business and operations of the Company.
Certain of these factors are discussed at "Item 1. Description of
Business-Factors That May Influence Future Results."

     The Company commenced providing consulting and development services for
computer software and systems in Israel in 1986 and in the United States in
1991. In March 1993, the Company diversified its business through the
acquisition of a facility in Israel that manufactures semiconductors using CMOS


                                       14
<PAGE>

process technology and the proprietary IC designs of its customers. Since such
date through the end of 1996, the Company conducted its business through two
business segments: the Computer Segment and the Semiconductor Segment.

    Due to changes in the Company's voting control in Tower, commencing in 1997,
the Company accounted for its interest in Tower's results using the equity
method including its pro rata share of Tower's net income as equity. The Company
therefore believes that the statement of operations for the year ended December
31, 1997 is not comparable with those of prior years.

COMPUTER SOFTWARE SERVICES AND SYSTEMS

     The Company's Computer Segment commenced operations in Israel in 1986 with
revenues attributable to the Company's Israeli subsidiaries accounting for 51%,
39%, and 37% of the total revenues of this segment during 1995, 1996 and 1997,
respectively. The decreasing percentage is primarily due to the increasing
revenues from operations in the United States. The Computer Segment's operations
in the United States have had a cumulative operating loss since commencing
operations in 1991, reflecting primarily the significant expenditures intended
to generate revenues over the long term rather than in current periods. The
Company started to realize the benefits of these expenditures towards the end of
1994, achieving significant revenue growth and improved operating results in
these operations in 1995. In 1996 and 1997 the Company invested heavily in the
development and marketing of these products, resulting in increased operating
losses.

    Costs relating to software product development are capitalized (in
accordance with applicable accounting principles for software development) to
the extent that they are incurred after the technological feasibility of the
product has been established and management considers that these costs are
recoverable from expected future revenues. When the foregoing criteria are not
satisfied, R&D costs relating to product development are expensed as incurred.
The Company's results of operations for 1995, 1996 and 1997 reflect $914,000,
$997,000 and $1.0 million respectively, of R&D expenses (net of government
grants) attributable to the Computer Segment. In addition, based on an
evaluation by management of the net realizable value of software costs
associated with certain of its products under development, the Company recorded
writedowns and amortized previously capitalized software costs totaling
$183,000, $881,000 and $2,016,000 in 1995, 1996 and 1997 respectively, included
in costs of sales.

     As of December 31, 1995, 1996 and 1997, capitalized software development
costs reflected on the balance sheet were $4.4 million, $5.2 million and $4.6
million, respectively. As of December 31, 1997, all of the capitalized software
costs relate to the Company's EPSM product which is in beta testing. There have
been no full product sales of the EPSM to date and there can be no assurance
that the Company will in fact derive significant revenues from EPSM. Costs
related to new software modules are capitalized in accordance with applicable
accounting principles as described above.

     Applicable accounting principles require that capitalized software costs be
periodically reviewed and are written down to net realizable value. Possible
additional writedowns of capitalized software costs associated with the
products above may significantly affect operating results in 1997 and future
periods. See "Item 1. Business Factors Which May Affect Future Results General
Factors - Capitalization of Software Development Costs; Possibility of Future
Writedowns".

     Gross profit margins in the Israeli operations of the Computer Segment,
continue to experience downward pressure due to increased labor costs resulting
from the relative shortage of qualified programmers and engineers. There can be
no assurance that the competitive market place for qualified engineers will not
continue to affect margins in future periods.

SEMICONDUCTOR MANUFACTURING

    Tower is an independent foundry manufacturer of semiconductor ICs on silicon
wafers and provider of related design and other services. As a foundry, Tower
manufactures wafers using its advanced production capability and the proprietary
IC designs of its customers. Tower manufactures primarily differentiated ICs
rather than commodity products. These ICs are incorporated into a wide range of
products in diverse markets, including computer and office equipment,
communication products and consumer electronics.

    Tower commenced operations as an independent business in March 1993, when it
acquired its manufacturing facility from National Semiconductor Corporation (the
"Acquisition"). From the Acquisition through the end of 1995, Tower increased
its sales and profitability by (i) expanding its customer base, (ii) expanding
its manufacturing capacity through installation of new equipment, improvement of
equipment utilization, reduction of cycle time and streamlining of the
manufacturing process, (iii) reducing costs through improvement of equipment,
process yields and operational efficiencies and realization of economies of
scale, and (iv) advancing its process technology. This allowed Tower to improve
its gross profit and operating margins from commencement of operations through
the end of 1995.

    As a result of (i) the end of Tower's purchase agreement with a major
customer, (ii) the reduction in orders from other customers and (iii) the
prevailing weakness in the demand for semiconductors products generally, Tower
operated its manufacturing facility substantially below capacity for part of
1996. Commencing in the fourth quarter of 1996 and into 1997, utilization
improved, primarily as a result of improvement in the personal computer and
peripheral end markets and certain price reductions implemented by Tower. As a
result of the improved utilization and the effect of Tower's successful cost
reduction and efficiency enhancement efforts, Tower was able to increase its
sales despite the reduction in prices and return to its previous levels of
profitability.

    Beginning in the fourth quarter of 1997 and continuing into 1998, Tower
experienced reduced orders resulting in underutilization of capacity. Tower
believes that the reduced order levels reflect the conditions in the market for
semiconductor products. Tower also continues to see downward pressure on prices
from both current and potential customers. In March 1998, Tower announced that
it expected to operate at a loss for the first half of 1998, with an estimated
first quarter loss of $0.13 per share.

    In 1996, Tower modified its capital plans, scaling back its capacity
expansion plan and increasing the resources allocated to Tower's technology
advancement plan and to improvements in infrastructure and operating procedures.
Tower does not currently intend to increase significantly the overall capacity
of its facility in 1998. Tower intends, however, to continue to make
expenditures during 1998 as part of its ongoing process technology advancement.
See "Item 1. Description of Business - Semiconductor Segment - Process
Technology," and "Item 1. Description of Business - Semiconductor Segment -
Manufacturing Facility".

</TABLE>

YEARS ENDED DECEMBER 31, 1997 AND 1996

    SALES. Computer Segment sales increased in all areas of activity, although
the increase was primarily due to a 23% increase in Computer Hardware-VAR sales
and a 113% increase in PHD software sales.

    GROSS PROFIT.  The decrease in gross profits as a percentage of Computer
Segment sales was primarily attributable to (i) the writedown of $1.7 million
in previously capitalized development costs associated with the Company's PHD-TM
and CybrCard products, (ii) continued development and production costs of the
Company's CybrCard product causing a gross loss of over $1 million, (iii) the
increased percentage of sales attributable to Computer Hardware-VAR sales which
characteristically have lower gross profit margins, and (iv) a decrease in
profitability in the Company's Israeli consulting systems and software activity,
due to increased direct labor costs.

    R&D. All R&D expenses in 1997 were attributable to the Company's EPSM
product for which development costs were no longer capitalized. For additional
discussion of R&D costs in the Computer Segment, see "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of
Operations-General".

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. ("SG&A"). The increase in
Computer Segment SG&A nominally and as a percentage of segment sales was
entirely due to increases of $4.1 million and $2.4 million in SG&A expenses
associated with the marketing and general introduction of the Company's PHD and
CybrCard products, respectively.

    OPERATING INCOME (LOSS). The decrease in operating income was primarily due
to the aforementioned decrease in gross profits and increase in SG&A expenses.


                                       16
<PAGE>

    INCOME TAXES. The increase in income taxes in 1997 was primarily due to
establishment of a $5.5 million valuation allowance against tax benefits
associated with United States federal tax loss and foreign tax credit
carryforwards.

    NET LOSS. The increase in the net loss is primarily attributable to the
aforementioned (i) increased direct costs due to writedown of development costs
associated with the Company's PHD and CybrCard products previously
capitalized and since discontinued development and production costs of the
Company's CybrCard product, (ii) marketing and general introduction of the
Company's PHD and CybrCard products and (iii) the tax expense resulting from
the valuation allowance recorded.

YEARS ENDED DECEMBER 31, 1996 AND 1995

    SALES. The decrease in Semiconductor Segment sales was entirely due to a
decrease in average sales price, resulting from a general downturn in the market
for semiconductor products during the second half of 1996. Computer Segment
sales increased due to a 35% increase in sales from the Company's United States
operations, attributable to a 93% increase in Computer Hardware-VAR sales and a
102% increase in PHD software sales, partially offset by a decrease in revenues
from consulting services.

    GROSS PROFIT. The decrease in gross profit as a percentage of Semiconductor
Segment sales was primarily attributable to the impact of increased costs
associated with the depreciation of the cost of the expansion of Tower's
manufacturing facility and the operation of the plant below capacity during the
second half of 1996 as well as the decrease in average sales price referred to
above. The decrease in gross profits as a percentage of Computer Segment sales
was primarily attributable to (i) the increased percentage of sales attributable
to Computer Hardware-VAR sales, which characteristically have lower gross profit
margins, and (ii) a decrease in profitability in the Company's Israeli
consulting systems and software activity, due to increased direct labor costs.

    R&D. The increase in R&D expenses in the Semiconductor Segment reflected
higher process development expenses related to the implementation of Tower's
technology advancement plan. For a discussion of R&D costs in the Computer
Segment, see "Item 7. Management's Discussion and Analysis of Financial
Condition and Results of Operations-General".

    SG&A. The increase in SG&A and SG&A as a percentage of sales for the
Semiconductor Segment was primarily attributable to increased marketing expenses
and professional fees. The increase in Computer Segment SG&A as a percentage of
segment sales was primarily attributable to SG&A expenses associated with the
marketing and general introduction of the Company's PHD and CybrCard products,
as well as a decrease in the Segment's Israeli operations without a commensurate
decrease in the SG&A of such operations.

    OPERATING INCOME.  The decrease in operating income was primarily due to
the aforementioned decrease in gross profits.

    GAIN ON CHANGES IN OWNERSHIP INTEREST IN SUBSIDIARY. The gain in 1995 was
from Tower's public offering, net of certain expenses. Minority interests in
this gain was approximately $10.5 million.

    INCOME TAXES. The increase in the effective tax rate for the year ended
December 31, 1996 was primarily attributable to (i) the recording in 1995 of a
non-taxable gain on changes in ownership interests in subsidiaries related to
the public offering of stock by the Company's Tower subsidiary, and (ii) the
recording of taxes payable on a dividend distributed to the Company by its Tower
subsidiary in 1996.

LIQUIDITY AND CAPITAL RESOURCES

    As of December 31, 1997, DSSI and its wholly-owned subsidiaries had working
capital of $4.1 million (including unrestricted cash and cash equivalents of
$1.2 million) and DSI Israel had working capital of $3.4 million (net of short
term bank credit of $1.1 million). Although there is no legal restriction
preventing disposition of the Company's investments or the distribution to the
Company of their earnings, cash of subsidiaries that are not wholly-owned is
generally not available for use by DSSI or other subsidiaries.

    DSSI has financed the operations of its wholly owned subsidiaries from the
proceeds of a public offering in 1993, an institutional private placement in


                                       17
<PAGE>

June 1994 and the receipt of cash dividends from Tower in December 1996 and
1997. DSSI believes that it has adequate liquidity to finance its ongoing
corporate activities. However in order to continue financing its PHD activities
the Company will require additional financing. If the Company is unable to
obtain such financing on commercially reasonable terms, it may have to
discontinue PHD's operations. There can be no assurance that the Company will
obtain the resources to finance its PHD product development and marketing
efforts. 

Due to the high costs associated with Cybrcard's marketing of consumer
multimedia products, the Company does not currently intend to develop and market
additional multimedia entertainment products in 1998. The Company, however, is
actively pursuing projects in the multimedia area in which the Company would
have responsibility for design and development of products which would be
marketed and sold by others. It is contemplated that in any such projects the
cost of development would be covered by the party with responsibility for the
marketing of the product.

In February 1998, the Company and Databit entered into a term loan agreement
with a bank under which the Company borrowed $1.2 million. In connection
therewith, the Company granted security interests in all of its assets as
security for the loan. The loan is repayable in 22 monthly installments
beginning May 1, 1998, with interest at the bank's reference rate plus 1%
(currently 9.50%).

DSI Israel has satisfied its financial and operating requirements principally
through cash from operations and the net proceeds of its initial
public offering in December 1992. DSI Israel has at its disposal additional bank
credit should it require. Certain of its bank deposits serve as collateral for
bank loans and guarantees.

Although the Company has retained effective control of Tower, since the end of
December 1996, the Company no longer maintained voting control of more than 50%
of Tower's shares and, therefore, ceased to consolidate Tower's balance sheet
and in 1997 consolidated its operations on an equity basis.

    Tower has satisfied its financial and operating requirements principally
through cash from operations, Investment Center grants, an advance from a
customer and the net proceeds of its public offerings in 1994 and 1995. As of
December 31, 1997, Tower had working capital of $87.5 million, including cash,
short-term bank deposits and marketable securities of $83.9 million.

   IMPACT OF INFLATION AND CURRENCY FLUCTUATIONS

    During 1997 approximately 90% of the Company's sales were denominated in
dollars. The remaining portion is primarily denominated in NIS that are linked
to the dollar. Such sales transactions are negotiated in dollars, however, for
the convenience of the customer they are settled in NIS. These transaction
amounts are linked to the dollar between the date the transactions are entered
into until the date they are effected and billed for. Subsequent thereto,
through the date of settlement, amounts are primarily unlinked. The majority of
the Company's expenses in 1997 were in dollars or dollar-linked NIS and
virtually all the remaining expenses were in NIS. The dollar cost of the
Company's operations in Israel is influenced by the timing of, and the extent to
which, any increase in the rate of inflation in Israel over the rate of
inflation in the United States is not offset by the devaluation of the NIS in
relation to the dollar. During 1997, the NIS was devalued against the dollar by
approximately 8.8%, while the consumer price index in Israel increased by 7%.
The Company believes that the rate of inflation in Israel has had a minor effect
on its business to date. However, the Company's dollar costs in Israel will
increase if inflation in Israel continues, as it did in previous years, to
exceed the devaluation of the NIS against the dollar or if the timing of such
devaluation lags behind inflation in Israel.

    Tower has commitments outstanding in Japanese Yen incurred for certain
capital equipment expenditures. Tower purchases forward exchange contracts to
reduce its financial exposure to fluctuation in the Japanese Yen/US dollar
exchange rate resulting from such commitments. The Company does not engage in
any other hedging activities.

    As of December 31, 1997, virtually all of the Company's monetary assets and
liabilities that were not denominated in dollars or dollar-linked NIS were
denominated in NIS, and the net amount of such monetary assets and liabilities
was not material. In the event that in the future the Company has material net
monetary assets or liabilities that are not denominated in dollar-linked NIS,
such net assets or liabilities would be subject to the risk of currency
fluctuations.

YEAR 2000 COMPLIANCE

    The Company's software and hardware systems were developed relatively
recently and the Company therefore believes that the systems do not require
significant modifications to make them Year 2000 compliant. However, the Company
may face Year 2000 compliance issues in relation to projects it performed for
customers in the past, or as it seeks to coordinate with suppliers, customers
and others. Although the Company is not currently aware of any material Year
2000 compliance problems, an assessment has not been made of the anticipated
costs, problems and uncertainties associated with possible Year 2000 compliance
issues and the possible consequences to the Company.

SUMMARY QUARTERLY FINANCIAL DATA

    The following table sets forth certain unaudited quarterly financial
information for the Company for the years ended December 31, 1996 and 1997. This
information should be read in conjunction with the financial statements of the
Company and the notes thereto. The quarterly financial information for the year
ended December 31, 1997, reflects Tower's activity on the equity method, while
such information for the year ended December 31, 1996 reflects Tower's
activities on a fully consolidated basis. Therefore information for such periods
is not directly comparable.

                         REPORT OF INDEPENDENT AUDITORS
                  TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
                          DATA SYSTEMS & SOFTWARE INC.

We have audited the accompanying consolidated balance sheet of Data Systems &
Software Inc. ("the Company") and its subsidiaries as of December 31, 1997 and
the related consolidated statements of operations, changes in shareholders'
equity and cash flows for the year ended December 31, 1997. These consolidated
financial statements are the responsibility of the Company's Board of Directors
and management. Our responsibility is to express an opinion on these financial
statements based on our audit. 

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of the Company and its
subsidiaries as of December 31, 1997, and the results of their operations,
changes in shareholders' equity and cash flows for the year ended December 31,
1997, in conformity with generally accepted accounting principles.

                 TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF

We have audited the accompanying consolidated balance sheet of Data Systems &
Software Inc. ("the Company") and its subsidiaries as of December 31, 1996, and

financial statements are the responsibility of the Company's Board of Directors

We conducted our audits in accordance with generally accepted auditing standards
in Israel, including those prescribed by the Israeli Auditors' Regulations
(Auditor's Mode of Performance) - 1973, which auditing standards are
substantially identical to generally accepted auditing standards in the United
States. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Board of Directors and management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of the Company and its
subsidiaries as of December 31, 1996, and the results of their operations,
changes in shareholders' equity and cash flows for the years ended December 31,
1995 and 1996, in conformity with accounting principles generally accepted in
Israel and the United States. As applicable to these financial statementss, such
accounting principles are substantially identical in all material respects.

                  DATA SYSTEMS & SOFTWARE INC. AND SUBSIDIARIES
                   Notes to Consolidated Financial Statements
                  (dollars in thousands, except per share data)

NOTE 1 - GENERAL AND SIGNIFICANT ACCOUNTING POLICIES

(a) DESCRIPTION OF BUSINESS

Data Systems & Software Inc., a Delaware corporation ("DSSI"), through its
subsidiaries and affiliates (collectively, "the Company"), (i) provides
consulting and development services for computer software and systems and
pre-packaged software solutions, and is an authorized dealer and a
value-added-reseller of computer hardware, and (ii) engages in the manufacture
of semiconductors. The Company's shares are traded on the Nasdaq National
Market.

The industries in which the Company operates are characterized by rapid
technological development. Accordingly, the ability to anticipate changes in
technology and to develop and introduce new and enhanced products incorporating
new technologies on a timely basis are significant factors in the ability to
grow and remain competitive. Furthermore, substantial expenditures are required
for research and development ("R&D") and for new product introduction.

(b) USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS 

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

(c) SIGNIFICANT ACCOUNTING POLICIES

FOREIGN CURRENCY TRANSLATION

The currency of the primary economic environment in which the operations of the
Company are conducted is the United States dollar ("dollar"). Accordingly, the
Company uses the dollar as its functional currency. Transactions and balances
that are denominated in dollars are presented at their dollar amounts.
Transactions and balances in other currencies are remeasured into dollars in
accordance with the principles of Statement of Financial Accounting Standards
("SFAS") No. 52. 

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of all majority-owned
or controlled subsidiaries. Material intercompany balances and transactions have
been eliminated. The Company's principal subsidiaries are as follows:

                                                  Effective percentage ownership
                Name of subsidiary                      as of December 31,
                ------------------                      1996          1997
                                                       --------     --------
Tower Semiconductor Holdings 1993 Ltd. ("Holdings")      60.0%        60.0%
Tower                                                    24.6%        24.6%
Decision Systems Israel Ltd. ("DSI")                     79.6%        76.3%
International Data Operations, Inc.                     100.0%       100.0%
Databit Inc.                                            100.0%       100.0%

CASH AND CASH EQUIVALENTS

Cash and cash equivalents consist of cash and demand deposits in banks and
short-term investments (primarily time deposits and certificates of deposit)
with original maturities of three months or less.

INVESTMENTS IN SECURITIES

Marketable debt securities which the Company has the positive intent and ability
to hold to maturity are reflected at amortized cost, which approximates market
value. Non-current equity investments in which the Company does not have
significant influence are carried at cost.

INVENTORY

Inventories are stated at the lower of cost or market. Cost is determined for
raw materials, spare parts and supplies on the average cost method. For work in
process and finished goods, cost is determined on the basis of standard costs,
adjusted for variances as appropriate. For merchandise inventories, cost is
determined on the first-in, first-out method.

                      Notes to Consolidated Financial Statements
                    (dollars in thousands, except per share data)

INVESTMENTS

Gains or losses resulting from the effective reduction of the Company's holdings
in subsidiaries due to the sale of their shares are included in operating
results. 

Investments in 50% or less of the voting control of companies or other entities
over whose operating and financial policies the Company has the ability to
exercise significant influence ("affiliates") are accounted for by the equity
method. Pursuant to this method, the Company includes its share of the
affiliate's earnings or losses in its results of operations.

PROPERTY AND EQUIPMENT

Property and equipment are presented at cost, net of investment grants received
or receivable. Depreciation is calculated based on the straight-line method over
periods ranging from three to 25 years.

COMPUTER SOFTWARE DEVELOPMENT COSTS

Computer software development costs, presented net of participations from
others, are capitalized upon the establishment of technological feasibility for
costs that the Company believes will be recovered from anticipated revenues.
These determinations are made regularly by the Company on a product by product
basis. Amortization of these costs commences on the earlier of general release
to customers or the receipt of revenues from the product, based on the ratio of
current revenues to current and anticipated future gross revenues, but not less
than straight-line amortization over the expected economic life of each product
(primarily three years). Capitalized software development costs which exceed
their net realizable value at each balance sheet date, as determined by
management, are written off.

GOODWILL

Goodwill, included with other assets, represents the excess of cost over the net
carrying value of assets of subsidiaries acquired in purchase transactions.
Goodwill is amortized based on the straight-line method over periods ranging
from five to fifteen years. Management reviews goodwill (as well as property and
equipment and other long-lived assets) on a periodic basis to determine whether
events or changes in circumstances indicate that the carrying amount of such
assets may not be recoverable. Amortization expense related to goodwill amounted
to $409, $221 and $288 during the years ended December 31, 1995, 1996 and 1997,
respectively.

REVENUE RECOGNITION

Revenues are recognized as products are shipped or services are provided, except
for revenues from fixed-price contracts, which are recorded on the basis of the
percentage-of-completion method. Revenues from such contracts are recorded as
costs (primarily direct labor) are incurred, in the proportion that actual costs
incurred bear to total estimated costs. Percentage-of-completion estimates are
continually reviewed and any adjustments required are reflected in the period
when such estimates are revised. Losses on contracts, if any, are recognized in
the period in which the loss is determined.

RESEARCH AND DEVELOPMENT EXPENSES

("R&D") costs not qualifying for capitalization as software development costs,
net of related participations, are charged to operations as incurred.

STOCK-BASED COMPENSATION

The Company accounts for employee stock-based compensation in accordance with
Accounting Principles Board Opinion No. 25. In accordance therewith, the Company
records compensation for share options granted to employees at the date of grant
based on the difference between the exercise price of the options and the market
value of the underlying shares at that date, as well as for the fair value of
restricted shares issued to employees. Deferred compensation is amortized to
compensation expense over the vesting period of the underlying options. See Note
15 for pro forma disclosures required in accordance with SFAS No. 123.

ALLOWANCE FOR DOUBTFUL ACCOUNTS

The allowance for doubtful accounts is based on specific identification of
accounts considered to be doubtful of collection. The allowance for doubtful
accounts amounted to $540 and $438, at December 31, 1996 and 1997, respectively.
Bad debt expense was $288, $95 and $8 for the years ended December 31, 1995,
1996 and 1997, respectively.

                   Notes to Consolidated Financial Statements
                  (dollars in thousands, except per share data)

FOREIGN EXCHANGE AGREEMENTS

The Company (primarily through Tower), from time to time, has entered into
foreign exchange agreements (forward agreements) primarily as a hedge against
non-dollar equipment purchase commitments. Gains and losses on foreign exchange
agreements through the date that the equipment is received are deferred and
recorded to property and equipment, while gains and losses subsequent thereto,
through the date of actual payment of the liability, are included in financial
income or expenses.

INCOME TAXES

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes, as well as operating
loss, capital loss and tax credit carryforwards. Deferred tax assets and
liabilities are classified as current or noncurrent based on the classification
of the related assets or liabilities for financial reporting, or according to
the expected reversal dates of the specific temporary differences, if not
related to an asset or liability for financial reporting. No provision has been
recorded for taxes which might be owed on disposition of the Company's
investments or on distribution to the Company of their earnings, since the
Company intends to reinvest earnings indefinitely.

LONG-LIVED ASSETS

The Financial Accounting Standards Board (the "FASB") Statement No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of" requires that they be segregated and stated at the lower of the
expected net realizable value or cost. The carrying value of long-lived assets
is periodically reviewed to determine whether impairment exists. The review is
based on comparing the carrying amount of the assets to the undiscounted
estimated cash flows over the remaining useful lives. No impairment is indicated
as of December 31, 1997. The Company has adopted this statement and the impact
has not been significant.

BASIC AND DILUTED NET INCOME (LOSS) PER SHARE

The Company has adopted the provisions of Statement of Financial Accounting
Standard ("SFAS") No. 128 "Earnings per Share" (the "Statement"). The Statement
establishes standards for computing and presenting net income (loss) per share
and applies to entities with publicly held common stock or potential stock such
as employee stock options. The Statement replaces the presentation of primary
net income (loss) per share with a presentation of basic net income (loss) per
share and also requires, among other things, dual presentation of basic and
diluted net income (loss) per share for all entities with complex capital
structures. Basic net income (loss) per share excludes dilution and is computed
by dividing net income (loss) by the weighted average number of shares
outstanding for each period presented. Diluted net income (loss) per share is
computed by dividing net income (loss) by the weighted number of shares
outstanding plus the dilutive potential of common shares which will result from
the exercise of stock options. Prior periods have been restated to reflect the
requirements of the new statement.

The following is a reconciliation of the weighted average shares used in the
computation of basic and dilutive net income (loss) per share: (000's)

                                                 1995        1996        1997
                                               --------    --------    --------
Weighted average common shares
   outstanding used for basic
   net income (loss) per share                    7,026       7,340       7,369
Dilutive stock options                              281          --          --
                                               --------    --------    --------
Weighted average common shares
   outstanding used for dilutive
   net income (loss) per share                    7,307       7,340       7,369
                                               ========    ========    ========

No stock options were included in the computations for 1996 and 1997, as doing
so would have been a anti-dilutive of the per-share amounts for those years. The
number of stock options and warrants that could potentially dilute basic net
income (loss) per share in the future that were not included in the table above
in years ended December 31, 1995, 1996 and 1997 were 1,940, 2,022 and 1,911,
respectively.

EFFECTS OF RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income".
This statement is effective for financial statements issued for periods
beginning after December 15, 1997. Management has evaluated the effect on its
financial reporting from the adoption of this statement and believes that such
effect would be insignificant.

In June 1997, the FASB issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information" SFAS 131 requires the reporting of profit
and loss, specific revenue and expense items, and assets for reportable
segments. It also requires the reconciliation of total segment revenues, total
segment profit or loss, total segment assets and other amounts disclosed for
segments to the corresponding amounts in the general purpose financial
statements. SFAS 131 is effective for fiscal years beginning after December 15,
1997. The Company uses data at the subsidiary level to manage the operations and
the Company will expand its current footnote disclosure to meet this criteria.

In February 1998, the FASB issued SFAS No. 132 "Employers' Disclosure about
Pension and Other Post-retirement Benefits". SFAS 132 revises and standardizes
employers' disclosures regarding pension and other post-retirement benefit
plans. SFAS 132 is effective for fiscal years beginning after December 15, 1997.
Management has evaluated the effect on its financial reporting from the adoption
of this statement and believes that it is already in compliance with this
disclosure.

NOTE 2 - INVESTMENT IN TOWER

Since acquiring Tower, a manufacturer of semiconductor products, DSSI maintained
voting control of more than 50% of its shares, through Holdings. Tower's shares
are traded on the Nasdaq National Market. Although the Company has retained
effective control of Tower, as of the end of 1996 the Company no longer
maintained voting control of Tower and, therefore, ceased to consolidate Tower's
balance sheet as of December 31, 1996. As the Company's individual assets and
liabilities at December 31, 1996 and the consolidated statements of income for
the year ended December 31, 1997 do not include amounts related to Tower, the
Company's 1996 and 1997 income statements are not directly comparable. The
consolidated statements of operations reflect Tower's revenues and expenses on a
full-year basis for the years ended December 31, 1995 and 1996. See Note 8 for
summary financial information of Tower.

NOTE 3 - MARKETABLE DEBT SECURITIES

Marketable debt securities consist primarily of United States Treasury Bills at
yields to maturity ranging from 4.9% to 5.1% (1996 - 4.6% to 4.9%) and maturing
in January, 1998, such amount approximates market value.

and $233 as of December 31, 1996 and 1997, respectively, after deducting fund
balances maintained in the Company's name for the sole purpose of making
severance payments. Israeli law and labor agreements determine the obligations
of the subsidiaries in Israel to make severance and pension payments to
dismissed employees and to employees leaving employment in certain other
circumstances. The obligation for severance pay benefits, as determined by the
Israeli Severance Pay Law, is based upon length of service and last salary.
These obligations are substantially covered by regular deposits with recognized
severance pay and pension funds and by the purchase of insurance policies. The
amounts so funded are not reflected on the balance sheet, since they are not
under the control and management of these subsidiaries, but are controlled by
the funds and insurance companies. The pension plans are multi-employer and
independent of the Company. Therefore, no information is available regarding
their present value and the net assets available for benefits. Pension and
severance pay costs for 1995, 1996 and 1997 were approximately $2,173, $2,236
and $591, respectively.

NOTE 14 - COMMITMENTS AND CONTINGENCIES

(a) Leases Of Property And Equipment

Rental and leasing expenses for 1995, 1996 and 1997 amounted to $554, $625 and
$777, respectively. Future minimum lease payments on non-cancelable operating
leases as of December 31, 1997 are as follows:

         Year ending December 31,

                                        $3,190
                                        ======
(b) Guarantees

The Company has provided bank guarantees of approximately $1,284 as security for
payment of obligations of affiliates and other companies.

                  (dollars in thousands, except per share data)

(c) Royalties

Certain research and development programs are eligible for financial assistance
from the Office of the Chief Scientist of the Israeli Ministry of Industry and
Commerce or from the Israel-United States BIRD Foundation. In return, the
subsidiaries are obligated to pay royalties at a rate of 2% to 5% of sales of
products resulting from the research and development efforts, up to a maximum of
150% of the financing received.

(d) Legal Actions

The Company is a plaintiff in an action against a former officer who resigned in
April 1995, alleging destruction and misappropriation of property and data owned
by the Company. The employee has filed a counterclaim against the Company,
alleging breach by the Company of its employment and resignation agreements with
the employee and seeking compensatory damages of $750 and punitive damages of
$25,000. The Company is pursuing its claims against the employee and is
vigorously defending against his counterclaims. The Company accrued the full
amount of severance payable under the resignation agreement at the time of such
employee's resignation. Based on the opinion of legal counsel handling the
matter, the Company believes it is unlikely to incur additional material
liability in connection with the counterclaim.

Between June and September 1996, several suits were filed in the United States
on behalf of a purported class of Tower's shareholders who purchased or
otherwise acquired Tower's ordinary shares between May 25, 1995 and June 10,
1996, against Tower, its Co-Chief Executive Officers, its Chairman of the Board
of Directors and the Company. The actions have been consolidated in the United
States District Court for the District of New Jersey. The consolidated complaint
filed in the actions alleges that the defendants made misstatements and
omissions regarding, among other things (i) the relationship between Tower and a
major customer and (ii) Tower's process development efforts in connection
therewith, in violation of certain U.S. Federal securities laws. Tower has
indemnified the defendants, up to the limits permitted by the Israel Companies
Ordinance, from any liability arising out of the actions. Tower maintains
insurance policies that, under certain conditions, cover actions of this type up
to an aggregate amount of $20,000. The Company is unable to determine at this
time with any certainty the ultimate outcome of the aforementioned matter or its
effect if any, on the Company's financial condition, operating results and
business. However, the Company believes it has meritorious defenses and is
defending the actions vigorously.

(e) Employee Retirement Savings Plan (401K)

The Company sponsors a tax deferred retirement savings plan (401K) which permits
eligible employees to contribute varying percentages of their compensation up to
the limit allowed by the Internal Revenue Service. The 401(K) Plan also provides
for discretionary Company contributions. No discretionary contributions were
made for the years ended December 31, 1995, 1996 and 1997.

NOTE 15 - SHAREHOLDERS' EQUITY

(a) Stock Option Plans

The Company's stock option plans provide for the granting to officers, directors
and other key employees of options to purchase shares of common stock at not
less than 85% of market value on the date of grant. The purchase price must be
paid in cash. To date, the Company has issued options under the plans at market
value. All options expire within five to ten years from the date of the grant.
The options generally vest over a one to three year period from the date of
grant of the option. The authorized number of options is 2,000,000 and the
number remaining available for issuance is 247,358.

The weighted average grant-date fair value of the 226,500 and 53,500 options
granted during 1996 and 1997 amounted to $3.56 and $5.24 per option,
respectively. The Company utilized the Black-Scholes option pricing model to
estimate fair value, utilizing the following assumptions for the respective
years (all in weighted averages):

                                    1995        1996           1997

Had compensation cost for the Company's option plans been determined based on
fair value at the grant dates for awards made in 1996 and 1997 under such plans
in accordance with SFAS No. 123, the Company's pro forma net income (loss) and
earnings (loss) per share would have been as follows:

The pro forma information in the above table also gives effect to the
application of SFAS No. 123 on the share option plans of the Company's
subsidiaries.

(b) Warrants

The Company has from time to time issued warrants primarily as compensation to
underwriters in connection with public stock offerings and to investors as part
of a private placement by the Company of common stock and warrants. All warrants
issued to date have been at exercise prices equal to or greater than market
value on the date of issuance. The effect of warrant issuance on the Company's
results of operations for all years presented is immaterial. A summary of
warrant activity follows:

(c) Stock Award

In March 1996, the Company granted 100,000 shares of common stock to its Chief
Executive Officer. The shares vest over a three-year period. Deferred
compensation in the aggregate amount of $587 was recorded against additional
paid-in capital at the date of grant, of which $150 and $196 was amortized to
compensation expense during 1996 and 1997, respectively.

(d) Other

In March 1996, the Company's Board of Directors adopted a stockholder rights
plan providing for the distribution of common stock purchase rights at the rate
of one right for each share of the Company's common stock held by shareholders
of record as of the close of business on April 1, 1996. The rights plan is
designed to deter coercive takeover tactics, including the accumulation of
shares in the open market or through private transactions, and to prevent an
acquirer from gaining control of the Company without offering a fair price to
all of the Company's shareholders. Each right initially entitles shareholders to
buy one-half of a share of common stock of the Company for $15. Generally, the
right will be exercisable only if a person or group acquires beneficial
ownership of 15% of more of the Company's common stock or commences a tender or
exchange offer upon consummation of which such person or group would
beneficially own 15% or more of the Company's common stock. If any person
("Acquiring Person") becomes the beneficial owner of 15% or more of the
Company's common stock, other than pursuant to a tender or exchange offer for
all outstanding shares of the Company approved by a majority of the Company's
independent directors, then, subject to certain exceptions set forth in the
rights plan, each right not owned by the Acquiring Person or related parties
will entitle its holder to purchase, at the right's then current exercise price,
shares of the Company's common stock (or in certain circumstances - as
determined by the Board of Directors - cash, other property or other securities)
having a value of twice the right's then current exercise price. The Company
will generally be entitled to redeem the rights at one half of one cent per
right at any time until 10 days (subject to extension) following a public
announcement that a 15% position has been acquired. The rights plan will expire
in March 2006.

NOTE 17 - RELATED PARTY BALANCES AND TRANSACTIONS

Other assets include a non-interest bearing loan of $277 and $357, at December
31, 1996 and 1997, respectively, made to an executive officer of the Company. In
addition, the Company approved a loan of up to $650, bearing interest at an
annual rate of 7%, to its Chief Executive Officer. The balance of this loan as
of December 31, 1997 was approximately $650. Such loan is repayable in
installments over a period of five years. The Company paid consulting and other
fees to directors of $82, $85 and $45 for the years ended December 31, 1995,
1996 and 1997, respectively. Sales for the years ended December 31, 1995, 1996
include $1,160, and $102, respectively, to an affiliate. No sales to affiliates
were made in 1997. Approximately $152 and $66, received from affiliates for
expense reimbursement during the years ended December 31, 1995 and 1997,
respectively, was reflected as a reduction of selling, general and
administrative expenses. No amount was received in 1996. The Company paid legal
fees for services rendered and out-of-pocket disbursements to a firm in which a
related party is a principal, of approximately $535, $450 and $401 for the years
ended December 31, 1995, 1996 and 1997, respectively. Approximately $10 and
$117, included in other current liabilities, was owed to this firm as of
December 31, 1996 and 1997, respectively.

NOTE 18 - GAIN ON CHANGES IN OWNERSHIP INTERESTS IN SUBSIDIARIES

Tower conducted a public offering in July 1995, which resulted in a decrease in
the Company's effective interest in Tower to 24.6%. As a result of the
offerings, the Company recognized a gain on changes in ownership interests in
subsidiaries of $26,339 in 1995.

Detailed information of the stock offering is as follows:

                                                                  July

                                                                -------
    Number of shares issued (in thousands)                        3,205

    Total net proceeds of offering                              $88,068
    Company's effective ownership interest before transaction      32.5%
    Company's effective ownership interest after transaction       24.6%

No deferred taxes were recorded in respect of the gains, as the Company's
investment in Tower is essentially permanent in duration (see Note 18).

The valuation allowance relates principally to net operating loss and capital
loss carryforwards and Federal foreign tax credit carryforwards. Due to the
history of losses in the Company's United States operations, a valuation
allowance has been established against all deferred tax assets relating to such
items. 

As of December 31, 1997, deferred tax assets of $279 are classified as other
current assets (1996 - $205) and $200 as other assets (1996 - $2,433).

NOTE 21 - FINANCIAL INSTRUMENTS

(a) General

A financial instrument is defined as cash, evidence of an ownership interest in
an entity, or a contract that imposes on one entity a contractual obligation
either to deliver or receive cash or another financial instrument to or from a
second entity. Examples of financial instruments include cash and cash
equivalents, trade accounts receivable, loans, investments, trade accounts
payable, accrued expenses, options and forward contracts.

                   Notes to Consolidated Financial Statements
                  (dollars in thousands, except per share data)

In accordance with SFAS Nos. 105, 107, and 119, the Company makes certain
disclosures with regard to financial instruments, including derivatives. These
disclosures include, among other matters, the nature and terms of derivative
transactions, information about significant concentrations of credit risk, and
the fair value of financial assets and liabilities.

(b) Forward Exchange Agreements

The Company, through Tower, has entered into forward exchange agreements to
manage exposure to equipment purchase commitments denominated in Japanese yen.
These transactions qualified for hedge accounting in accordance with generally
accepted accounting principles and, accordingly, the results of such
transactions have been recorded concurrently with the realization of the related
items (i.e., receipt of the equipment and payment of the related liability). The
Company does not hold or issue derivative financial instruments for trading
purposes.

(c) Presentation Of Foreign Exchange Transactions In The Financial Statements

Losses recognized on forward exchange transactions amounted to $1,661 and $3,598
for 1995 and 1996, respectively. Of these amounts, $1,130 and $3,002 were
capitalized to property and equipment, respectively; and the remaining amounts
of $531 and $596 were reflected in financing expenses, respectively. No such
transactions are reflected for 1997. See Note 2.

(d) Fair Value Of Financial Instruments

Fair values are estimated for financial instruments included in current assets
and current liabilities at book value, due to the short maturity of such
instruments. Fair value for long-term debt is estimated based on the current
rates offered to the Company for debt with the same remaining maturities. Fair
value of long-term equity marketable investments is estimated based on market
value. The estimation of fair value for non-marketable long-term equity
investments (book value of $70,696 as of December 31, 1997) was not practicable.
The estimated fair value of the Company's financial instruments was not
materially different than their book value. See Note 7(b) for information
regarding the book and fair market value of the Company's investment in Tower.

(e) Concentrations Of Credit Risk

The Company is subject to credit risk through its trade receivables. As of
December 31, 1997, approximately 10% of the trade accounts receivable were due
from a major Israel government-owned company which, despite experiencing
financial difficulties, continues to pay its trade receivables over extended
credit periods. The remaining balance consists primarily of receivables from
various customers.

                                AUDITORS' REPORT
                             TO THE SHAREHOLDERS OF
                            TOWER SEMICONDUCTOR LTD.

We have audited the accompanying consolidated balance sheets of Tower
Semiconductor Ltd. ("the Company") and subsidiaries as of December 31, 1997 and
1996, and the related consolidated statements of income, changes in
shareholders' equity and cash flows for each of the three years in the period
ended December 31, 1997. These financial statements are the responsibility of
the Company's Board of Directors and management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards, including those prescribed by the Israeli Auditors' Regulations
(Auditor's Mode of Performance) - 1973, which standards are substantially
identical to generally accepted auditing standards in the United States. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by the
Board of Directors and management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements present fairly, in all
material respects, the consolidated financial position of the Company and
subsidiaries as of December 31, 1997 and 1996, and the consolidated results of
their operations, changes in shareholders' equity and cash flows for each of the
three years in the period ended December 31, 1997, in accordance with generally
accepted accounting principles in Israel. As applicable to these financial
statements, such accounting principles are substantially identical in all
material respects to generally accepted accounting principles in the United
States, except as indicated in Note 18.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (dollars in thousands, except per share data)

NOTE 1 - DESCRIPTION OF BUSINESS AND GENERAL

            A. Description of Business

            Tower Semiconductor Ltd. ("the Company"), incorporated in Israel,
            commenced operations in March 1993. The Company is an independent
            "foundry" manufacturer of semiconductor integrated circuits on
            silicon wafers. As a foundry, the Company manufactures wafers using
            its advanced production capabilities and the proprietary integrated
            circuit designs of its customers. The industry in which the Company
            operates is characterized by wide fluctuations in supply and demand.
            Such industry is also characterized by the complexity and
            sensitivity of the manufacturing process, by high levels of fixed
            costs, and by the need for constant improvements in production
            technology.

            In March 1993, the Company acquired its plant in Israel from a
            subsidiary of National Semiconductor Corporation, a U.S. corporation
            ("National"), in an acquisition ("Acquisition") accounted for by the
            purchase method of accounting. Pursuant to a shareholders'
            agreement, as of December 31, 1997, National maintained the right to
            nominate one member of the Company's Board of Directors.

            During 1996 and 1997, respectively, the Company established a wholly
            owned marketing subsidiary in the U.S. and a 51%-owned (on a fully
            diluted basis) ASIC design center subsidiary in Israel. The
            operations of these subsidiaries were not material to the Company's
            financial position or results of operations as of December 31, 1997
            and 1996 and for the years then ended.

            The Company's ordinary shares are traded on the Nasdaq National
            Market.

            B. Use of Estimates in Preparation of Financial Statements

            The preparation of financial statements in conformity with generally
            accepted accounting principles ("GAAP") requires management to make
            estimates and assumptions that affect the reported amounts of assets
            and liabilities and disclosure of contingent assets and liabilities
            as of the date of the financial statements, and the reported amounts
            of revenues and expenses during the reporting periods. Actual
            results could differ from those estimates.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

            A. Principles of Consolidation

            The Company's financial statements include the financial statements
            of the Company and its majority-owned subsidiaries, after
            elimination of material intercompany transactions and balances.

            B. Cash and Cash Equivalents


                                      F-28
<PAGE>

                    TOWER SEMICONDUCTOR LTD. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (dollars in thousands, except per share data)

            Cash and cash equivalents consist of deposits in banks and
            short-term investments (primarily time deposits and certificates of
            deposit) with original maturities of three months or less.

            NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

            C. Marketable Debt Securities

            Marketable debt securities which the Company has the positive intent
            and ability to hold to maturity are reflected at amortized cost.

            D. Inventories

            Inventories are stated at the lower of cost or market. Cost is
            determined for raw materials, spare parts and supplies on the basis
            of average cost per unit. Cost is determined for work in process and
            finished goods on the basis of actual production cost.

            E. Investments in Other Entities

            Long-term investments in other entities, over whose operating and
            financial policies the Company does not have the ability to exercise
            significant influence, are presented at cost.

            F. Property and Equipment

            Property and equipment are presented at cost, net of investment
            grants received or receivable, and less accumulated depreciation and
            amortization. Depreciation is calculated based on the straight-line
            method over the estimated economic lives of the assets or terms of
            the related leases, as follows:

                  Land and buildings under capital lease         14-25 years
                  Machinery and equipment                          5 years
                  Transportation vehicles                          7 years

            Management reviews property and equipment and other long-lived
            assets on a periodic basis to determine whether events or changes in
            circumstances indicate that the carrying amount of such assets may
            not be recoverable.

            G. Income Taxes

            The Company records deferred income taxes to reflect the net tax
            effects of temporary differences between the carrying amounts of
            assets and liabilities for financial reporting purposes and for tax
            purposes. Deferred taxes are computed based on the tax rates
            anticipated to be in effect (under applicable law at the time the
            financial statements are prepared) when the deferred taxes are
            expected to be paid or realized.

            Deferred tax liabilities and assets are classified as current or
            noncurrent based on the classification of the related asset or
            liability for financial reporting, or according to the expected
            reversal dates of the specific temporary differences, if not related
            to an asset or liability for financial reporting.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (dollars in thousands, except per share data)

            H. Revenue Recognition

            Revenues are recognized upon delivery. An accrual for estimated
            returns, computed primarily on the basis of historical experience,
            is recorded at the time of sale.

            NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

            I. Research and Development

            Research and development costs are charged to operations as
            incurred. Amounts received or receivable from the Government of
            Israel and others, as participation in research and development
            programs, are offset against research and development costs.

            J. Earnings per Ordinary Share

            Basic earnings per ordinary share are calculated based on the
            weighted average number of ordinary shares outstanding for each
            period presented (including retroactive effect of shares issued upon
            exercise of share options during each period) and give effect to
            shares issuable from share options whose exercise is probable based
            on specific calculations. Diluted earnings per share include the
            effects of all outstanding options which have a dilutive effect on
            earnings per share. Diluted earnings per share data for 1996 and
            1995 has not been presented, since such data did not differ by more
            than 5% from basic earnings per share. See Note 18 for disclosure of
            1997 earnings per share data in accordance with U.S. GAAP. Basic and
            diluted earnings per share data in accordance with U.S. GAAP, as
            well as the data relating to earnings and number of shares used for
            such calculations, were not materially different from the data
            presented in accordance with Israeli GAAP for 1996 and 1995.

            K. Foreign Exchange Agreements

            The Company, from time to time, enters into foreign exchange
            agreements as a hedge against non-dollar equipment purchase
            commitments. Gains and losses on such agreements through the date
            that the equipment is received are deferred and recorded to property
            and equipment, while gains and losses subsequent thereto, through
            the date of actual payment of the liability, are included in
            financing income, net.

            L. Functional Currency and Transaction Gains and Losses

            The currency of the primary economic environment in which the
            Company conducts its operations is the U.S. dollar ("dollar").
            Accordingly, the Company uses the dollar as its functional and
            reporting currency. Financing income, net, reflects net foreign
            currency transaction losses, which amounted to $384, $677 and $473
            in 1997, 1996 and 1995, respectively.

            M. Stock-Based Compensation

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (dollars in thousands, except per share data)

            The Company accounts for employee stock-based compensation in
            accordance with Accounting Principles Board Opinion No. 25,
            "Accounting for Stock Issued to Employees." Pursuant to this
            accounting standard, the Company records deferred compensation for
            share options granted to employees at the date of grant based on the
            difference between the exercise price of the options and the market
            value of the underlying shares at that date. Deferred compensation
            is amortized to compensation expense over the vesting period of the
            underlying options. See Note 13B for pro forma disclosures required
            in accordance with Statement No. 123, "Accounting for Stock-Based
            Compensation" ("SFAS 123"), of the Financial Accounting Standards
            Board.

            in exchange for 10.0% of Sayfun's equity and, according to the
            agreement, is obligated to invest another $3,000 in exchange for
            additional equity in Sayfun that will increase the Company's
            aggregate investment to 15% of Sayfun's equity (including certain

NOTE 7 - PROPERTY AND EQUIPMENT (cont.)

            B. Investment Grants

            In connection with the formation of the Company, the Investment
            Center of the Ministry of Industry and Trade of the State of Israel
            ("Investment Center"), under its "approved enterprise" program,
            approved an investment program for expenditures on buildings and
            equipment in the aggregate amount (as amended) of approximately
            $96,850. The approval certificate was granted in respect of a
            benefit track providing the Company with investment grants at a rate
            of 38% of the investments included in such certificate. The Company
            completed its investments in respect of this program during 1996,
            and received final approval from the Investment Center in November
            1997 for the investments effected in respect of this program.

            In January 1996, an investment program ("existing program") for
            expansion of the Company's plant in the aggregate amount of $239,579
            was approved by the Investment Center. The approval certificate was
            granted in respect of a benefit track providing the Company with
            investment grants at a rate of 34% of the investments included in
            such certificate. Pursuant to the approval, the investments in
            respect of this program are required to be completed by December 31,
            1998.

            Receipt of the above grants is subject to various conditions. In the
            event the Company fails to comply with such conditions, the Company
            may be required to repay all or a portion of the grants received
            plus interest and certain inflation adjustments. In order to assure
            fulfillment of the conditions related to the receipt of investment
            grants, floating liens were registered in favor of the State of
            Israel on substantially all assets of the Company. In management's
            opinion, the Company has been in full compliance with the conditions
            through December 31, 1997.

            In respect of the existing program, the Company has invested
            approximately $105,500 through December 31, 1997 and estimates that
            the total investment within the framework of such program will
            aggregate approximately $145,000 by December 31, 1998. In January
            1998, the Company applied to the Investment Center for a two-year
            extension of time to complete its investments under the existing
            program. Based on preliminary discussions with the Investment
            Center, the Company's management is of the opinion that such
            extension will be approved.

NOTE 8 - SHORT-TERM DEBT

            Short-term debt consists primarily of unlinked, non-interest bearing
            short-term loans received from a bank for the payment of Value Added
            Tax (VAT).

            In December 1997 and January 1998, the Company received letters of
            intent from certain Israeli banks. Pursuant to such letters of
            intent, the banks (see Note 11) and a third bank will make available
            to the Company, at its request, short-term credits in the aggregate
            amount of $75,000, of which $60,000 will be available through
            December 1999 and the rest through December 1998, at terms to be
            agreed upon by the parties prior to the actual receipt of any
            credits by the Company.

            B. Other Related Party Balances and Transactions

            Trade accounts receivable as of December 31, 1997 includes $5,080
            due from National, primarily for wafer purchases ($9,500 as of
            December 31, 1996).

            The Company purchased materials and received services from National
            during 1997 in the aggregate amount of $55 ($260 and $2,101 for 1996
            and 1995, respectively). See Note 16E.

            Pursuant to a management agreement with Data Systems & Software Inc.

            entitled to management fees from the Company of $40 per month in
            1997, 1996 and 1995. The management agreement can be terminated by

            notice requirements.

            In addition, the Company purchases computerized testing equipment
            from a related party supplier in the normal course of business. The
            Company's purchases from this supplier aggregated $962, $18, and
            $282 for 1997, 1996 and 1995, respectively.

NOTE 11 - LONG-TERM DEBT

            In connection with the Acquisition, the Company assumed certain
            long-term bank loans of National in the aggregate amount of $12,064
            ("Original Term Loans"). The Original Term Loans are indexed to the
            dollar and bear interest (payable quarterly) at an annual rate of
            6%. The Company is obligated to repay the principal of the Original
            Term Loans in quarterly installments commencing in March 1993 and
            ending in May 1998

            The bank that provided the Original Term Loans, together with
            another bank (collectively, "Banks"), agreed to make new loans ("New
            Term Loans") to the Company to repay and effectively extend the
            maturity of all principal installments due on the Original Term
            Loans. The aggregate balance of the New Term Loans is repayable in
            12 equal quarterly payments commencing in May 2000.

            The Banks also agreed that, as long as the Company maintains
            deposits at the Banks with original maturities of at least one year
            from the date of deposit, the annual interest rate on the New Term
            Loans (up to the amount of such deposits) will be 0.3% over the
            interest rate that the Company receives on the deposits. The portion
            of the New Term Loans not covered by such deposits will bear annual
            interest at the three-month Libor rate plus 1.25%.

            The agreements with the Banks restrict the Company's ability to
            place liens on its assets (other than to the State of Israel in
            respect of investment grants) without the prior consent of the
            Banks. Furthermore the agreements contain certain restrictive
            financial covenants. As of December 31, 1997, the Company was in
            full compliance with such covenants.

NOTE 12 - OTHER LIABILITIES (cont.)

            B. Employee Termination Benefits

            Israeli law and labor agreements determine the obligations of the
            Company to make severance payments to dismissed employees and to
            employees leaving employment under certain other circumstances. The
            liability for severance pay benefits, as determined by Israeli Law,
            is based upon length of service and the employee's most recent
            salary. This liability is primarily covered by regular deposits made
            by the Company into recognized severance and pension funds and by
            insurance policies purchased by the Company. The amounts so funded
            are not reflected on the balance sheet, since they are controlled by
            the fund trustees and insurance companies and are not under the
            control and management of the Company.

            Expenses relating to employee termination benefits were
            approximately $1,674 , $1,311 and $1,303 for 1997, 1996 and 1995,
            respectively.

NOTE 13 - SHAREHOLDERS' EQUITY

            A. Share Purchase Plan

            In December 1993, the Company sold 234,497 ordinary shares to key
            senior management employees pursuant to a share purchase plan for an
            aggregate purchase price of $678. Loans extended by the Company
            financed approximately $672 of the aggregate purchase price required
            to be paid by the employees. Such loans are denominated in new
            Israeli shekels ("NIS") and are linked to the Israeli Consumer Price
            Index ("CPI"). Through December 31, 1997, all shares under the plan
            were fully vested. The shares are subject to certain restrictions on
            sale or transfer. The employee's obligation to repay loans received
            to finance the purchase of the ordinary shares is secured by such
            shares and is repayable upon the sale of the ordinary shares in
            accordance with a formula set forth in the share purchase plan.

            B. Share Option Plans

            The Company maintains two share option plans, which were adopted in
            1994 and 1995, respectively. The plans provide for the grant of
            options to employees (including senior management) to purchase
            ordinary shares at exercise prices which may not be less than 85% of
            the market value of the ordinary shares at the date of grant. In
            addition, pursuant to the plans, the terms of the options granted
            may not exceed ten years from the first grant date under each plan.

            Options granted to date become vested over a four-year period
            according to various vesting schedules. In July 1996, the exercise
            price of vested options granted under the 1994 plan was reduced from
            primarily $17 per share to $13 per share, while the exercise price
            of non-vested options granted was reduced from primarily $17 per
            share to $9.125 per share (the market value of the shares at such
            time). The exercise price of all options granted under the 1994 plan
            after July 1996 has been the market value of the shares on the date
            of grant.

            and 265,000 options granted during 1997, 1996 and 1995 amounted to
            $7.56, $4.50 and $11.20 per option, respectively. The Company

NOTE 15 - INCOME TAXES (cont.)

            A. Approved Enterprise Status (cont.)

            The tax benefits are also conditioned upon fulfillment of the
            requirements stipulated by the 1959 Law and the regulations
            promulgated thereunder, as well as the criteria set forth in the
            certificates of approval. In the event of a failure by the Company
            to comply with these conditions, the tax benefits could be canceled,
            in whole or in part, and the Company would be required to refund the
            amount of the canceled benefits, plus interest and certain inflation
            adjustments. In management's opinion, the Company has been in full
            compliance with the aforementioned conditions through December 31,
            1997.

            The Company has net operating loss carryforwards of approximately
            $355 as of December 31, 1997, which may be carried forward for an
            unlimited period of time.

NOTE 16 - COMMITMENTS AND CONTINGENCIES

            A. Legal Proceedings

            Between June and September 1996, several suits were filed in the
            United States on behalf of a purported class of the Company's
            shareholders who purchased or otherwise acquired the Company's
            ordinary shares between May 25, 1995 and June 10, 1996, against the
            Company, its Co-Chief Executive Officers, its Chairman of the Board
            of Directors and DSSI. The actions have been consolidated in the
            United States District Court for the District of New Jersey. The
            consolidated complaint filed in the actions alleges that the
            defendants made misstatements and omissions regarding, among other
            things (i) the relationship between the Company and a major customer
            and (ii) the Company's process development efforts in connection
            therewith, in violation of certain U.S. Federal securities laws.

            The Company has indemnified the defendants, up to the limits
            permitted by the Israel Companies Ordinance, from any liability
            arising out of the actions. The Company maintains insurance policies
            that, under certain conditions, cover actions of this type up to an
            aggregate amount of $20,000. The Company is unable to determine at
            this time with any certainty the ultimate outcome of the
            aforementioned matter or its effect if any, on the Company's
            financial condition, operating results and business. However, the
            Company believes it has meritorious defenses and intends to defend
            the actions vigorously.

NOTE 16 - COMMITMENTS AND CONTINGENCIES (cont.)

            B. Leases

            The Company's offices and engineering and manufacturing operations
            are located in a building complex situated in an industrial park in
            Migdal Haemek, Israel. These premises are currently occupied under a
            long-term lease from the Israel Lands Authority, which expires in
            2032. The Company has no obligation for lease payments related to
            this lease through the year 2032.

            The Company occupies certain other premises under various operating
            leases. The obligations under such leases were not material as of
            December 31, 1997.

            C. Purchase Agreements

            The Company from time to time enters into long-term purchase
            agreements with customers. Pursuant to such agreements, the Company
            is committed to sell, and the customer is committed to purchase
            (subject to reductions in certain circumstances), a specific monthly
            output derived from the start of processing of silicon wafers
            ("wafer starts") at prices stipulated in the agreements. The
            Company's existing purchase agreement with National expires on
            February 28, 1998 (see also below). From commencement of the
            Company's operations through December 31, 1997, a substantial
            portion of the Company's production has been sold in the framework
            of these agreements.

            In May 1995, the Company and National signed an amendment to their
            original purchase agreement (as previously amended). The amendment
            called for an increase in the number of wafer starts per month that
            the Company was committed to sell to National ("additional output").
            In consideration for such increase, National provided the Company
            with the amount of $28,875 as an advance in respect of the
            additional output. The advance bears interest at the three-month
            Libor rate. Any amounts of the advance not offset against sales of
            additional output to National through October 1, 1999 were to be
            retained by the Company without any obligation to National.

            In January 1998, the Company and National signed a new purchase
            agreement ("new agreement"), effective March 1, 1998 through
            February 28, 2000, with an option to extend the agreement for an
            additional one year. The new agreement replaces all prior purchase
            agreements with National, as well as portions of other agreements
            pertaining to wafer purchases. Pursuant to the new agreement, the
            Company is committed to sell, and National is committed to purchase
            (subject to reductions in certain circumstances), quantities as set
            forth in the agreement. Such quantities are lower than the
            commitments of the Company and National pursuant to the prior
            agreements mentioned above. The new agreement also

                  (dollars in thousands, except per share data)

            establishes mechanisms for determining the prices to be charged by
            the Company during the period of the agreement.

NOTE 16 - COMMITMENTS AND CONTINGENCIES (cont.)

            C. Purchase Agreements (cont.)

            In addition, the mechanism for offsetting the aforementioned advance
            payment received from National was revised and extended National's
            right to offset the advance payment against wafer purchases through
            February 2000. Under certain circumstances, the Company may be
            required to repay National a portion of the advance payment still
            outstanding at that time. The portion of the advance outstanding as
            of December 31, 1997 that is expected to be offset in 1998 in
            accordance with the new agreement is presented as a current
            liability.

            In the framework of certain purchase agreements with customers, the
            Company is entitled to receive warrants to purchase share capital of
            the customer under conditions stipulated in the agreements.

            In June 1996, the Company reached an understanding for the
            termination of a purchase agreement with a former major customer.
            Sales to such customer accounted for approximately 8% and 9% of the
            Company's sales in 1996 and 1995, respectively.

            D. Profit Sharing Plan

            The Company maintains an employee profit sharing plan. Under the
            terms of this plan (i) 7.5% of the Company's profit before taxes, as
            defined ("PBT"), each year is to be divided among all employees of
            the Company, including senior management (the allocation of which is
            based on salary and a yearly performance score for each employee)
            and (ii) 2.5% of PBT each year is to be divided among key senior
            management employees. The profit sharing award with respect to each
            year is paid in two installments in the following year. The
            Company's expenses pursuant to the profit sharing plan were $2,312,
            $1,231 and $2,561 for 1997, 1996 and 1995, respectively.

            E. Mutual Services Agreements

            In connection with the Acquisition, the Company and National entered
            into a mutual services agreement. The agreement, as extended from
            time to time, is effective through February 28, 1998. In accordance
            with the aforementioned agreement, the Company paid National $55 for
            various services and National paid the Company $361 for certain
            activities in 1997 ($260 and $800, respectively, for 1996; and
            $2,101 and $714, respectively, for 1995).

            F. Other Principal Agreements

            The Company from time to time, in the normal course of business,
            enters into long-term agreements with various entities for the joint
            development of products and processes utilizing technologies owned
            by both the other entities and the Company ("joint ventures").
            Certain of such agreements contain commitments by the Company and/or
            the other entities to purchase

            specific quantities of the products developed. As of December 31,
            1997, the Company's aggregate commitment to invest in such joint
            ventures was $5,167.

NOTE 16 - COMMITMENTS AND CONTINGENCIES (cont.)

            G. Other Commitments

                  (1)   In consideration for research and development funding
                        received by the Company and another party, aggregating
                        $780 as of December 31, 1997, from the BIRD - Binational
                        Industrial Research and Development Foundation ("BIRD"),
                        the Company and the other party has undertaken to pay
                        royalties amounting to primarily 2.5% of the gross sales
                        from products developed from the research and
                        development financed, not to exceed 150% of the grants
                        received.

                  (2)   Receipt of certain research and development grants from
                        the Government of Israel is subject to various
                        conditions. In the event the Company fails to comply
                        with such conditions, the Company may be required to
                        repay all or a portion of the grants received. In
                        management's opinion, the Company has been in full
                        compliance with the conditions through December 31,
                        1997.

NOTE 17 - FINANCIAL INSTRUMENTS

            A financial instrument is defined as cash, evidence of an ownership
            interest in an entity, or a contract that imposes on one entity a
            contractual obligation either to deliver or receive cash or another
            financial instrument to or from a second entity. Examples of
            financial instruments include cash and cash equivalents, trade
            accounts receivable, loans, investments, trade accounts payable,
            accrued expenses, options and forward contracts.

            In accordance with Statements No. 105, 107 and 119 of the FASB, the
            Company makes certain disclosures with regard to financial
            instruments, including derivatives. These disclosures include, among
            other matters, the nature and terms of derivative transactions,
            information about significant concentrations of credit risk, and the
            fair value of financial assets and liabilities.

            A. Foreign Exchange Agreements

            The Company, from time to time, enters into foreign exchange
            agreements to manage exposure to equipment purchase commitments
            denominated in Japanese yen. These transactions qualify for hedge
            accounting in accordance with GAAP and, accordingly, the results of
            such transactions are recorded concurrently with the realization of
            the related items (i.e., receipt of the equipment and payment of the
            related liability). The Company does not hold or issue derivative
            financial instruments for trading purposes.

            B. Credit Risk of Financial Instruments, Including Derivatives

            The face or contract amounts of derivatives do not represent amounts
            exchanged by the parties and, accordingly, are not a measure of the
            exposure of the Company through its use of derivatives.

NOTE 17 - FINANCIAL INSTRUMENTS (cont.)

            B. Credit Risk of Financial Instruments, Including Derivatives
               (cont.)

            The Company is exposed to credit-related losses in respect of
            derivative financial instruments in a manner similar to the credit
            risk involved in the realization or collection of other types of
            assets. In management's estimation, due to the fact that derivative
            financial instrument transactions are entered into solely with
            financial institution counterparties, it is not expected that such
            counterparties will fail to meet their obligations. See E below with
            regard to credit risks in respect of trade accounts receivable.
            Substantially all remaining financial instruments held by the
            Company are due from governmental entities and, accordingly, the
            Company's credit risk in respect thereof is negligible.

            C. Presentation of Foreign Exchange Transactions in the Financial
               Statements

            There were no outstanding foreign exchange agreements as of December
            31, 1997 and the results of such agreements were not material for
            1997.

            The aggregate contract amount of foreign exchange agreements
            outstanding as of December 31, 1996 was $1,016. The credit risk on
            these transactions was not material as of December 31, 1996 and no
            deferred losses existed at that date.

            Losses recognized on foreign exchange agreements amounted to $3,598
            in 1996. Of this amount, $3,002 was capitalized to property and
            equipment during 1996 and the remaining amount of $596 was reflected
            in financing expenses (1995 - $1,661, $1,130 and $531,
            respectively).

            D. Fair Value of Financial Instruments

            The estimated fair values of the Company's financial instruments did
            not materially differ from their respective carrying amounts as of
            December 31, 1997 and 1996.

            E. Concentrations of Credit Risk

            Most of the Company's trade accounts receivable (73% as of December
            31, 1997) were due from the Company's two major customers, both of
            whom are large multinational companies (see Note 14A).

            price of $11.90 per share were outstanding during 1997 but were not
            included in the computation of diluted earnings per share because
            the exercise prices of the options were greater than the average
            market price of the ordinary shares. The options, which expire in

            (c) Anything to the contrary herein notwithstanding, if at any time
during the Employment Period the Company breaches any of its obligations
hereunder or there shall occur a "Change in Control of the Company" (as

plan sponsored by the Company or a subsidiary thereof, shall become the

representing 20% or more of the combined voting power of the Company's then
outstanding securities ordinarily (and apart from rights accruing in special
circumstances) having the right to vote in the election of directors, as a
result of a tender or exchange offer, open market purchases, privately
negotiated purchases or otherwise, or (iv) at any time during a period of two
consecutive years, individuals who at the beginning of such period constituted
the Board of Directors of the Company shall cease for any reason to constitute
at least a majority thereof, unless the election or the nomination for election
by the Company's stockholders of each new director during such two-year period
was approved by a vote of at least two-thirds of the directors then still in
office who were directors at the beginning of such two-year period or (v) any
other event shall occur that would be required to be reported in response to
Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Exchange Act.

            (d) During any Consulting Period hereunder, the Executive shall

to the immediately preceding year (using as the basis of such computation the
"Consumer Price Index for All Urban Consumers -- New York and Northeastern New

Directors of the Company. Upon each such review the Executive's salary rate may
be increased to such rate as shall be considered appropriate and as shall be
fixed by the Board. The salary shall be paid to the Executive in appropriate
installments in accordance with the Company's usual and customary payroll
practices for executive officers. The Executive's election pursuant to

sole discretion. Such fund shall not be used by the Company for any purpose
other than the payment of consulting fees to the Executive.

            (b) During the Employment Period and any Consulting Period the
Executive shall also be reimbursed by the Company for reasonable business
expenses actually incurred or paid by him, consistent with the policies of the
Company, in rendering to the Company the services provided for herein. In lieu

and the Executive shall be eligible to participate in the Company's 1994 Stock

Company or any parent, subsidiary or successor of it) that is engaged in whole
or in part in a business that is in substantial and direct competition with the

otherwise publicly traded.

            6.    Termination.

            (a) The Company may terminate this Agreement and all the Company's
obligations hereunder, except for obligations accrued but unpaid to the
effective date of termination, only for the Executive's willful failure to
perform his obligations under Paragraph 1 hereof. Such termination shall be
effected by notice thereof, hand delivered by the Company to the Executive and,
except as hereinafter provided, shall be effective as of the tenth day after
receipt by the Executive of such notice.

            (b) If, within the 10-day period following the date of receipt of

such obligations, the termination shall not be effective.

            (c) This Agreement may be terminated by the Executive upon not less
than ten days' prior written notice to the Company because of a material breach
by the Company of its obligations hereunder or immediately upon written notice
to the Company of the occurrence of a Change in Control of the Company. In such

be) will then be terminated, the Executive shall continue to receive all the
compensation provided for in Paragraph 2 hereof and shall be entitled to all the
benefits other-

the case may be), notwithstanding such termination. An election by the
Executive, pursuant to Paragraphs 1(b) or 1(c) hereof, to function as a
Consultant may not be rescinded by the Executive, and after such election the
Executive may terminate only for a material breach of this Agreement during the
Consulting Period or a Change in Control of the Company.

            (d) In the event of a termination of this Agreement by the Executive
as a result of the material breach of this Agreement by the Company of any of
its obligations hereunder or a Change in Control of the Company, or in the event
of the termination of the Executive's employment by the Company in breach of
this Agreement, the Executive shall not be required to seek other employment in
order to mitigate his damages hereunder, and no amounts received from any such
employment shall reduce any amount that the Company would otherwise be required
to pay to him as a result of such breach.

            (e) In the event that the Executive institutes any legal action to
enforce his rights under, or to recover damages for breach of this Agreement,
the Executive, if he is the prevailing party, shall be entitled to recover from
the Company any actual expenses of such action, including attorneys' fees and
disbursements, incurred by him.

            7. Confidentiality. The Executive shall not during the term of this
Agreement or thereafter disclose to any person, firm or corporation, except as
otherwise required by law, any information concerning the business, clients or
affairs of the Company that he may have acquired in the course of, or as an
incident to, his employment by the Company, for his own benefit or that of any
such person, firm or corporation, or to the detriment or intended or probable
detriment of the Company.

the Delaware General Corporation Law or other applicable law.

            9. Remedies. The Company hereby waives, and will not assert, any
right to set off the amount of any claims, liabilities, damages or losses the

hereunder, and any amounts payable to or otherwise accrued for the account of
the Executive in respect of any period prior to the effective termination of
this Agreement shall be paid as provided in this Agreement.

            10. Arbitration. Any controversy or claim arising out of or relating

accordance with the rules of the American Arbitration Association, and judgment
upon such award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The arbitrator shall not have the power to direct
equitable relief. The arbitration shall be held in New York, New York, or such
other place as may be agreed upon at the time by the parties to the arbitration.

            11. Governing Law. This Agreement shall be governed by and construed
and enforced in accordance with the laws of the State of New York.

            12. Termination of Prior Employment Agreement. This Agreement
supersedes and replaces in its entirety the 1994 Employment Agreement, which is
hereby terminated and without further force or effect, except as to amounts
accrued and payable to the Executive thereunder as of the date hereof.

            13. Entire Agreement. This Agreement constitutes the whole agreement
of the parties hereto in reference to any employment or consultation of the
executive by the Company and in reference to any of the matters or things herein
provided for or hereinbefore discussed or mentioned in reference to such
employment, all prior agreements, promises, representations and understandings
relative thereto being herein merged.

Dear George:

      Geotek and DSI hereby agree that all principal amounts outstanding on the

defined below) shall be converted (the "Conversion") on the Conversion Date into
shares of Common Stock of Geotek ("Common Stock") in accordance with the terms
hereof. Upon consummation of the Conversion all obligations of Geotek under the
Note and any related documentation shall be satisfied. DSI shall be entitled to
receive in the Conversion a whole number of shares of Common Stock (the "Common

      2. All Property (as hereinafter defined) held by the Bank shall be subject
to a security interest in favor of the Bank as security for any and all
Liabilities (as hereinafter defined). The term "Property" shall mean the balance
of every deposit account of the Borrower with the Bank or any of the Bank's
nominees or agents and all other obligations of the Bank or any of its nominees
or agents to the Borrower, whether now existing or hereafter arising, and all

indebtedness evidenced by this Note and all other indebtedness, liabilities and
obligations of any kind of the Borrower (or any partnership or other group of
which the Borrower is a member) to (a) the Bank, (b) any group of which the Bank
is a member, or (c) any other person if the Bank has a participation or other
interest in such indebtedness, liabilities or obligations, whether (i) for the
Bank's own account or as agent for others, (ii) acquired directly or indirectly
by the Bank from the Borrower or others, (iii) absolute or contingent, joint or
several, secured or unsecured, liquidated or unliquidated, due or not due,
contractual or tortious, now existing or hereafter arising, or (iv) incurred by

by the Bank in connection with any such indebtedness, liabilities or obligations
or any of the Property (including any sale or other disposition of the
Property).

      3. Prepayment. The Borrower shall have the right to prepay this Note in
whole at any time or in part from time to time (but if in part, in the principal
amount of $5,000.00 or any whole multiple thereof), in each case upon not less
than 10 days prior written notice to the Bank, without penalty or premium,
provided that on each prepayment the Borrower shall pay accrued interest on the
principal amount so prepaid to the date of such prepayment, and each partial
prepayment shall be applied to the installments of this Note in the inverse
order of their stated maturities.

      4. Manner of Payment. All payments by the Borrower on account of
principal, interest or fees hereunder shall be made in lawful money of the

required or permitted by law or otherwise), such payment shall be made not later
than the next succeeding business day, and such extension shall be included in
computing interest in connection with such payment.

B. EVENTS OF DEFAULT: REMEDIES

      If any of the following events shall occur and be continuing:

      1. the Borrower shall fail to make any payment of principal of or interest
on this Note, or any fee provided for herein, when due:

      2. the Borrower shall default in the performance or observance of any
covenant or agreement contained herein;

      3. an event of default or default shall occur and be continuing under any
other agreement, document or instrument executed and delivered to the Bank by
the Borrower or any guarantor or hypothecator relating to any Liabilities;

      4. any representation or warranty made by or on behalf of the Borrower in

delivered to the Bank by or on behalf of the Borrower shall at any time prove to
have been incorrect when made in any material respect;

      5. the Borrower or any Subsidiary (as hereinafter defined) shall default
in the payment of principal of or interest on any indebtedness for borrowed
money (including any such indebtedness in the nature of a lease) or shall
default in the performance or observance of the terms of any instrument pursuant
to which such indebtedness was created or is secured, the effect of which
default is to cause or permit any holder of any such indebtedness to cause the
same to become due prior to its stated maturity (and whether or not such default
is waived by the holder thereof);

      6. any change in the condition or affairs (financial or otherwise) of the
Borrower or any Subsidiary shall occur which, in the opinion of the Bank,
increases its risk with respect to the loan evidenced by this Note or impairs
any security therefor;

unpaid, or shall not be released, discharged, dismissed, stayed or fully bonded
for a period of thirty (30) days or more after its entry, issue or levy, as the
case may be;

      8. the Borrower or any Subsidiary shall become insolvent (however
evidenced) or be unable, or admit in writing its inability, to pay its debts as
they mature; or

      9. the Borrower or any Subsidiary shall make an assignment for the benefit
of creditors, or a trustee, receiver or liquidator shall be appointed for the
Borrower or any Subsidiary or for any of their property, or the commencement of
any proceedings by the Borrower or any Subsidiary under any bankruptcy,
reorganization, arrangement of debt, insolvency, readjustment of debt,
receivership, liquidation or dissolution law or statute (including, if the
Borrower is a partnership, its dissolution pursuant to any agreement or
statute), or the commencement of any such proceedings without the consent of the
Borrower or any Subsidiary and such proceedings shall continue undischarged for
a period of 30 days, or the death of the Borrower (if an individual) or any
member of the Borrower (if a partnership); [or]
<PAGE>

      10. [Other] (4)

then, and in any such event, the Bank may declare the entire unpaid principal
amount of this Note and all interest and fees accrued and unpaid hereon to be
forthwith due and payable, whereupon the same shall become and be forthwith due
and payable, without presentment, demand, protest or notice of any kind, all of
which are hereby expressly waived by the Borrower. The balance of every account
of the Borrower with, and each claim of the Borrower against, the Bank existing
from time to time shall be subject to a lien and subject to be set off against
any and all Liabilities, including those hereunder.

For purposes of this Note, the term "Subsidiary" shall mean and include any
corporation of which more than 50% of the outstanding shares of capital stock
having ordinary voting power to elect a majority of the Board of Directors of
such corporation (irrespective of whether or not at the time capital stock of
any other class or classes of such corporation shall or might have voting power
upon the occurrence of any contingency) is at the time, directly or indirectly,
owned by the Borrower or by one or more other Subsidiaries.

its officers, directors or independent accountants.

      2. No Waiver; Remedies Cumulative. No failure on the part of the Bank to
exercise, and no delay in exercising any right hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise by the Bank of any
right hereunder preclude any other or further exercise thereof or the exercise
of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

      3. Costs and Expenses. The Borrower shall reimburse the Bank for all costs
and expenses incurred by it and shall pay the reasonable fees and disbursements

hereof shall inure to the benefit of the Bank and its successors and assigns,
including subsequent holders hereof.

      7. Severability. The provisions of this Note are severable, and if any
provision shall be held invalid or unenforceable in whole or in part in any
jurisdiction, then such invalidity or unenforceability shall not in any manner
affect such provision in any other jurisdiction or any other provision of this
Note in any jurisdiction.

    in this Note.

<PAGE>

the Borrower and the Bank and the Borrower further irrevocably consents to the
service of process in any such action or proceeding by the mailing of a copy of
such process to the Borrower at the address set forth below. In the event of
litigation between the Borrower and the Bank over any matter connected with this

      Member FDIC

                               SECURITY AGREEMENT

     **   Wherever used herein, the name Bank Leumi Trust Company of New York is

      In consideration of financial accommodations heretofore extended or to be
extended or continued to the undersigned the BANK LEUMI TRUST COMPANY OF NEW
YORK (the "Bank"), the undersigned hereby agrees as follows:

      1. As security for the full and prompt payment of any and all Liabilities
(as hereinafter defined), the undersigned hereby assigns and transfers to the
Bank and grants the Bank a security interest in all Security (as hereinafter

proportions as the Bank shall in its sole discretion determine.

      2. The term "Liabilities" as used herein shall include all liabilities and
obligations of any kind of the undersigned (or any partnership or other group of

or other interest in such liabilities or obligations, whether (a) for the Bank's
own account or as agent for others, (b) acquired directly or indirectly by the
Bank from the undersigned or others, (c) absolute or contingent, joint or
several, secured or unsecured, liquidated or unliquidated, due or not due,

execute, file and record any notices, affidavits or other documents and take all
such other actions as the Bank may deem appropriate to protect or perfect its
security interest in the Security or to otherwise accomplish the purposes of
this agreement. The undersigned hereby agrees to pay on demand, and/or
authorizes the Bank to charge its account with the cost of, any and all filing,
recording and other fees and expenses which the Bank deems appropriae in order
to protect or perfect its security or to otherwise accomplish the purpose of
this agreement, including without limitation the cost of all searches of public
records as the Bank in its sole discretion shall require. The undersigned will
promptly notify the Bank of the imposition at any time of any lien or
encumbrance upon any of the Security. Notwithstanding the foregoing, the

undersigned will defend the Security against all claims and demands of all
persons at any time claiming the same or any interest therein adverse to the
Bank.

installments, or otherwise modify the terms of, or release, any of the Security;

to take all actions and proceedings in its own name or in the name of the
undersigned or any other appropriate person in order to remove or contest such
liens, encumbrances, taxes, assessments, claims, actions or demands; or to
refrain from doing any of the foregoing, all without affecting the Liabilities
and the Security and without notice or liability to or the consent of the

its willful misconduct, and in no event for consequential damages.

      6. The undersigned will pay to the Bank all costs and expenses incurred

respect to the Security and agrees to deliver to the Bank, upon demand, all

      9. Upon the occurrence of an Event of Default (as hereinafter defined),

      10. As used in this agreement, the term" Event of Default" shall mean: (a)
nonpayment when due of any of the Liabilities or failure on the part of an
Obligor (as hereinafter defined) to observe or perform any agreement or
obligation to be observed or performed hereunder or under any other agreement or
instrument relating to the Liabilities or to any other liability or obligation
of an Obligor to the Bank; (b) making by an Obligor of any misrepresentation to

forthwith on demand by the Bank or to permit the inspection of any books or
records; (d) failure of an Obligor to pay, withhold, collect or remit when
assessed or due any tax, assessment or other sum payable with respect to any of

impairs the Security or increases the Bank's risk with respect to the
Liabilities; or (m) default (which shall be continuing) with respect to any
indebtedness of an Obligor to any other individual or entity if such default
would enable said individual or entity to accelerate the maturity of such
indebtedness.

      For the purposes of this agreement, the term "Obligor" shall include the
undersigned and any maker, drawer, acceptor, endorser, guarantor, hypothecator,
surety, accommodation party, or other party liable for any of the Liabilities in
addition to the undersigned.

      11. Notwithstanding the continued possession of the Security by the Bank,
whether on its own behalf or on behalf of others, the undersigned shall remain
liable for the payment in full of the Liabilities. The undersigned assumes all
liability and responsibility for the Security, and the obligation of the
undersigned to pay the liabilities shall in no way be affected or diminished by
reason of the fact that any of the Security may be lost, destroyed, stolen,
damaged or for any other reason whatsoever unavailable to the undersigned or
that the value of the Security shall be diminished. In the event of any partial
or complete loss or destruction of any of the Security by any means, the
undersigned shall, at its own expense, cause such repairs to be made as the Bank
may deem appropriate for its protection or, at the option of the Bank, replace
the Security with new Security having a value equal to the value of the lost or
destroyed Security prior to such loss or destruction. The undersigned agrees, at
its own expense, to keep all insurable Security insured against loss or damage
by fire, theft or any other risk to which the Security may be subject (including
without limitation such hazards as the Bank may specify), for the full insurable
value thereof, under policies and with insurers acceptable to the Bank, which
policies shall provide for all losses to be payable to the Bank and for at least
30 days prior notice to the Bank of any intended cancellation or modification of
the policy. The undersigned will deliver to the Bank on request policies or
certificates of such insurance with evidence of payment of the premium thereon.
If the undersigned fails to maintain said insurance, then, in addition to any
other right or remedy that the Bank may have and without waiving the
consequences of such default, the Bank may but need not obtain and maintain said
insurance, at the expense of the undersigned, which expense shall be deemed one
of the Liabilities and shall be payable to the Bank on demand. The Bank is
irrevocably authorized to file claims and shall have the sole right to adjust,
settle and collect claims under said insurance by such means, at such times, on
such terms and in the name of the Bank or the undersigned, as the Bank may see
fit, and in the name and on behalf of the undersigned to execute releases and
endorse checks or drafts payable in respect of any such insurance claims. All
sums received by the Bank from any such insurance may be held as part of the
Security and/or applied as hereinafter provided.

      12. The Bank, at any time, at its option, may apply all of any net cash
receipts from the Security (whether received on a sale of the Security in
accordance with paragraph 9 hereof, on collection in accordance with paragraph 5
hereof, as proceeds of insurance in accordance with paragraph 11 hereof, or
otherwise) to the payment, in whole or in part, of principal of and/or interest
on any or all of the Liabilities, whether or not then due, allocating the same
as it shall elect, making rebate of interest or discount to the extent required
by law and so as not to make the rate of interest ?pledged unlawful with respect
to the undersigned. If any Liabilities shall be contingent, the Bank may retain
a sufficient amount of the net cash receipts from the Security to cover the
largest aggregate sum which may become due or owing thereunder with prospective
interest, costs, expenses and attorneys' fees and shall not be charged with any
interest with respect thereto.

      13. Until the occurrence of an Event of Default or notice from the Bank
terminating or limiting the right of the undersigned to do so, or, in the case
of the collection, compromise, or adjustment of accounts receivable, until the
Bank takes any action pursuant to paragraph (5)(e) hereof, the undersigned may
sell or lease in the ordinary course of its regular business inventory
constituting a part of the Security and may collect, compromise and adjust
accounts receivable constituting a part of the Security, all on such terms as
the undersigned may in good faith deem advisable in the ordinary course of its
regular business, and may retain all sums so collected. Except as permitted by
this paragraph 13, the undersigned may not sell, lease, assign or otherwise
dispose of any of the Security without the prior written consent of the Bank. In
addition, the undersigned may not sell, assign or otherwise dispose of any
shares of stock or other securities now owned or hereafter acquired by the
undersigned which are issued by the same issuer and are of the same class as any
shares of stock or other securities constituting a part of the Security. The
undersigned shall keep all of the Non-Possessory Security (as described in
Schedule A hereto) at the undersigned's premises listed in Schedule A hereto and
shall not remove any of the Non-Possessory Security therefrom without the Bank's
prior written consent.

      14. In any litigation or legal proceeding arising out of, or relating to,
this agreement or any of the Liabilities or Security, in which the Bank and the
undersigned shall be adverse parties, the undersigned waives the right to
interpose any defense, set-off or counterclaim of any kind not directly arising
herefrom or therefrom, as the case may be, and also waives the right to a trial
by jury. In the event that the Bank brings any action or suit in any court of
record of New York State or the Federal Government to enforce any or all of the
Liabilities or any of the Bank's rights hereunder, service of process may be
made upon the undersigned by mailing a copy of the summons to the undersigned at
its chief executive office set forth in Schedule A hereto, and the undersigned
hereby irrevocably submits to the jurisdiction of any New York State or Federal
Court located in New York City over any action, suit or proceeding arising out
of any dispute between the undersigned and the Bank.

      15. If in its sole discretion the Bank deems it desirable, it may remove
any Security held by it from the place where it may now or hereafter be located
to any other place and deal with it there as herein provided.

      16. Upon the occurrence of an Event of Default, and at any time
thereafter, the Bank shall have and may exercise, without further notice, a
right of set-off and/or banker's lien against and in respect of any of the
Security then or thereafter held by the Bank. Any right of set-off exercised by
the Bank shall be deemed to have been exercised immediately on the occurrence of
an Event of Default, even though such set-off is made or entered on the books of
the Bank subsequent thereto.

      17. If the time for payment of principal of or interest on any of the
Liabilities or any other money payable hereunder or with respect to any of the
Liabilities is extended because said sum becomes due on a Saturday, Sunday or
public holiday, interest shall be payable for such extended time.

      18. The Bank shall not be deemed to have modified or waived any of its
rights hereunder or any terms or conditions hereof unless such modification or
waiver is in writing and signed by a duly authorized officer of the Bank. No
such modification or waiver, unless so expressly stated herein, shall be
effective as to any transaction which occurs subsequent to the date of such
modification or waiver nor shall it constitute a continuing modification or
waiver. No delay on the part of the Bank in exercising any power or right
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any power or right hereunder preclude any other or further exercise
thereof or the exercise of any other power or right. All rights and remedies of
the Bank with respect to the Liabilities or Security, whether evidenced hereby
or by any other instrument or paper, shall be cumulative and may be exercised
singularly or concurrently.

      19. The Bank may assign and/or transfer to any assignee or transferee of
any of the Liabilities any or all of the Security and the Bank's rights
hereunder with respect thereto, and thereafter the Bank shall be fully
discharged from all responsibility with respect to the Security so assigned
and/or transferred, Such assignee
<PAGE>

or transferee shall be vested with all the powers and rights of the Bank
hereunder with respect to such Security, but the Bank shall retain all rights
and powers hereby given with respect to any of the Security not so assigned or
transferred. The undersigned will not assert against any assignee or transferee
of any of the Liabilities any claims or defenses it may have against the Bank.

      20. The undersigned hereby waives presentment, notice of dishonor and
protest with respect to all instruments included in or evidencing the
Liabilities or the Security and, except as specified herein, any and all other
notices and demands whatsoever, whether or not relating to such instruments.

      21. The undersigned will indemnify and save the Bank harmless from and
against all loss or damage to it and any claims and actions, whether groundless
or otherwise, arising in connection with this agreement, the Liabilities or the
Security, and all costs and expenses (including attorneys' fees) incurred by the
Bank in respect thereof.

      22. If any term, condition or provision of this agreement or any other
agreement or document executed in connection herewith or in connection with any
of the Liabilities or Security is determined to be invalid or unenforceable,
such determination shall not affect the validity or enforceability of any other
term, condition or provision.

      23. Any demand upon or notice to the undersigned that the Bank may elect
to give shall be effective if deposited in the mails addressed to or otherwise
delivered to the undersigned at its chief executive office or if the undersigned
has notified the Bank in writing by registered mail of a change of address, at
the last address of which the Bank has received notice. Demands or notices
addressed or otherwise delivered to the address as which the Bank customarily
communicates with the undersigned shall also be effective.

      24. If any of the Security is or is to be attached to or installed or
located on real estate, the undersigned will upon demand furnish the Bank with a
disclaimer signed by all persons having an interest in said real estate of any
interest prior to the Bank's interest in the Security.

      25. From and after maturity (whether by acceleration or otherwise) of any
of the Liabilities, any unpaid balance remaining shall bear interest at the
higher of 12% per annum or 3% in excess of the rate specified in the instrument
evidencing the Liabilities. Anything in this agreement or any other agreement,
instrument or document to the contrary notwithstanding, in no event shall
interest on any Liability exceed the maximum rate permitted under any applicable
law or regulation, and if any provision of this agreement or any other
agreement, instrument or document is in contravention of any such law or
regulation, such provisions shall be deemed amended so provide for interest at
said maximum rate.

      26. The undersigned, if more than one, shall be jointly and severally
liable hereunder and all provisions hereof regarding the Liabilities or Security
shall apply to any Liability or any Security of any or all of them. This
agreement shall be binding upon the heirs, executors, administrators, successors
and assigns of the undersigned and shall inure to the benefit of the Bank and
its successors and assigns. For purposes of this agreement, the term "Bank"
shall include the Bank any and all subsidiaries of the Bank. If all Liabilities
shall at any time be paid in full, this agreement shall nonetheless remain in
full force and effect with respect to any Liabilities thereafter incurred. If
the undersigned is a corporation, this agreement shall be binding upon any other
corporation into or with which the undersigned shall be merged, consolidated,
reorganized or absorbed, or which shall acquire the undersigned's business or
substantially all of its assets. If the undersigned is a partnership, the
members thereof shall also be individually bound and liable hereunder and this
agreement shall continue in force notwithstanding any change in or termination
of such partnership, whether such change occurs through death, retirement or
otherwise. Except as otherwise provided herein, all terms used herein which are
defined in the Uniform Commercial Code of the State of New York shall have the
meanings therein stated. If this agreement shall differ in terms with any other
agreement or obligation or the terms of any of the Liabilities, that which gives
the Bank the greater right shall prevail.

      27. If any of the Security is applied on account of any of the
Liabilities, the undersigned shall not have any right of subrogation to the
Bank's right in any other Security held by the Bank with respect to the
Liabilities or any right of contribution from the Bank by reason thereof.

      28. The Bank is authorized to correct patent errors herein. This agreement
shall take effect immediately upon execution by the undersigned, and the
execution hereof by the Bank shall not be required as a condition to the
effectiveness of this agreement.

      29. Notwithstanding anything to the contrary contained herein, the term
"Security" as used herein shall be deemed to include any and all book-entry U.S.

undersigned as the Bank deems necessary or desirable in order to perfect the
Bank's security interest therein. The undersigned hereby gives notice to the
Bank, in the Bank's capacity as bailee and agent, of the Bank's security
interest in the aforementioned book-entry Treasury bills and other book-entry
securities.

      30. This agreement shall be interpreted, and all the rights and
obligations arising hereunder or from any document relating hereto shall be
determined, in accordance with the laws of the State of New York.

      Trust Company of New York
      Member FDIC

                               SECURITY AGREEMENT

     **   Wherever used herein, the name Bank Leumi Trust Company of New York is
          replaced with the name Bank Leumi USA.

      In consideration of financial accommodations heretofore extended or to be
extended or continued to the undersigned the BANK LEUMI TRUST COMPANY OF NEW
YORK (the "Bank"), the undersigned hereby agrees as follows:

      1. As security for the full and prompt payment of any and all Liabilities
(as hereinafter defined), the undersigned hereby assigns and transfers to the
Bank and grants the Bank a security interest in all Security (as hereinafter
defined). Said grant is made for the benefit of the Bank and or any others
having a participation or other interest in any of the Liabilities, in such
proportions as the Bank shall in its sole discretion determine.

      2. The term "Liabilities" as used herein shall include all liabilities and
obligations of any kind of the undersigned (or any partnership or other group of
which the undersigned is a member) of to (i) the Bank, (ii) any group of which
the Bank is a member or (iii) any other person if the Bank has a participation
or other interest in such liabilities or obligations, whether (a) for the Bank's
own account or as agent for others, (b) acquired directly or indirectly by the
Bank from the undersigned or others, (c) absolute or contingent, joint or
several, secured or unsecured, liquidated or unliquidated, due or not due,
contractual or tortious, now existing or hereinafter arising, or (d) incurred by
the undersigned as principal, surety, endorser, guarantor or otherwise, and
including without limitation all expenses, including attorneys' fees, incurred
by the Bank in connection with any such liabilities or obligations or any
Security therefor.

      3. The term "Security" as used herein shall include all of the property
described in Schedule A hereto.

      4. The right is granted to the Bank, in its discretion, to file one or
more financing statements (with or, to the extent permitted by law, without the
signature of the undersigned) under the Uniform Commercial Code naming the
undersigned as debtor and the Bank as secured party and indicating therein the
types or describing the items of Security herein specified. The undersigned will
execute, file and record any notices, affidavits or other documents and take all
such other actions as the Bank may deem appropriate to protect or perfect its
security interest in the Security or to otherwise accomplish the purposes of
this agreement. The undersigned hereby agrees to pay on demand, and/or
authorizes the Bank to charge its account with the cost of, any and all filing,
recording and other fees and expenses which the Bank deems appropriae in order
to protect or perfect its security or to otherwise accomplish the purpose of
this agreement, including without limitation the cost of all searches of public
records as the Bank in its sole discretion shall require. The undersigned will
promptly notify the Bank of the imposition at any time of any lien or
encumbrance upon any of the Security. Notwithstanding the foregoing, the
undersigned represents, warrants and covenants that all of the Security now
existing or hereafter arising or acquired is and will be owned by the
undersigned free and clear of all security interests, liens and encumbrances of
any kind, except for the security interest herein granted to the Bank. The
undersigned shall promptly pay when due all taxes and transportation, storage
and warehousing charges affecting or arising out of the Security. The
undersigned will defend the Security against all claims and demands of all
persons at any time claiming the same or any interest therein adverse to the
Bank.

      Notwithstanding the foregoing, the Bank shall base no obligation to comply
with any recording, re-recording, filing, re-filing, or other legal requirements
necessary to establish or maintain the validity, priority or enforceability of,
or the Bank's right in or to, the Security or any part thereof.

      5. The right is granted to the Bank, in its discretion, at any time, (a)

and to hold the same as a part of the Security and/or apply the same as
hereinafter provided; (b) to exchange any of the Security for other property
upon any reorganization, recapitalization, or other readjustment and in
connection therewith to deposit any of the Security with any committee or
depositary upon such terms as the Bank may determine, (c) in any bankruptcy or
similar proceeding to file a proof of claim for the full amount of the Security
and to vote such claim for or against any arrangement or with respect to any
other matter; (d) in its own name or in the name of the undersigned or any other

Security, (e) to extend the time of payment, arrange for payment in
installments, or otherwise modify the terms of, or release, any of the Security;
(f) to contest, pay and/or discharge all liens, encumbrances, taxes or
assessments on, or claims, actions or demands against, any of the Security and
to take all actions and proceedings in its own name or in the name of the
undersigned or any other appropriate person in order to remove or contest such
liens, encumbrances, taxes, assessments, claims, actions or demands; or to
refrain from doing any of the foregoing, all without affecting the Liabilities
and the Security and without notice or liability to or the consent of the

its willful misconduct, and in no event for consequential damages.

      6. The undersigned will pay to the Bank all costs and expenses incurred

satisfactory to the Bank or make such payment on account of the Liabilities as
the Bank may require.

      9. Upon the occurrence of an Event of Default (as hereinafter defined),

Liability, be immediately due and payable without notice, demand or presentment;

nonpayment when due of any of the Liabilities or failure on the part of an
Obligor (as hereinafter defined) to observe or perform any agreement or

of an Obligor to the Bank; (b) making by an Obligor of any misrepresentation to

forthwith on demand by the Bank or to permit the inspection of any books or

impairs the Security or increases the Bank's risk with respect to the
Liabilities; or (m) default (which shall be continuing) with respect to any
indebtedness of an Obligor to any other individual or entity if such default
would enable said individual or entity to accelerate the maturity of such
indebtedness.

      For the purposes of this agreement, the term "Obligor" shall include the
undersigned and any maker, drawer, acceptor, endorser, guarantor, hypothecator,
surety, accommodation party, or other party liable for any of the Liabilities in
addition to the undersigned.

      11. Notwithstanding the continued possession of the Security by the Bank,
whether on its own behalf or on behalf of others, the undersigned shall remain
liable for the payment in full of the Liabilities. The undersigned assumes all
liability and responsibility for the Security, and the obligation of the
undersigned to pay the liabilities shall in no way be affected or diminished by
reason of the fact that any of the Security may be lost, destroyed, stolen,
damaged or for any other reason whatsoever unavailable to the undersigned or
that the value of the Security shall be diminished. In the event of any partial
or complete loss or destruction of any of the Security by any means, the
undersigned shall, at its own expense, cause such repairs to be made as the Bank
may deem appropriate for its protection or, at the option of the Bank, replace
the Security with new Security having a value equal to the value of the lost or
destroyed Security prior to such loss or destruction. The undersigned agrees, at
its own expense, to keep all insurable Security insured against loss or damage
by fire, theft or any other risk to which the Security may be subject (including
without limitation such hazards as the Bank may specify), for the full insurable
value thereof, under policies and with insurers acceptable to the Bank, which
policies shall provide for all losses to be payable to the Bank and for at least
30 days prior notice to the Bank of any intended cancellation or modification of
the policy. The undersigned will deliver to the Bank on request policies or
certificates of such insurance with evidence of payment of the premium thereon.
If the undersigned fails to maintain said insurance, then, in addition to any
other right or remedy that the Bank may have and without waiving the
consequences of such default, the Bank may but need not obtain and maintain said
insurance, at the expense of the undersigned, which expense shall be deemed one
of the Liabilities and shall be payable to the Bank on demand. The Bank is
irrevocably authorized to file claims and shall have the sole right to adjust,
settle and collect claims under said insurance by such means, at such times, on
such terms and in the name of the Bank or the undersigned, as the Bank may see
fit, and in the name and on behalf of the undersigned to execute releases and
endorse checks or drafts payable in respect of any such insurance claims. All
sums received by the Bank from any such insurance may be held as part of the
Security and/or applied as hereinafter provided.

      12. The Bank, at any time, at its option, may apply all of any net cash
receipts from the Security (whether received on a sale of the Security in
accordance with paragraph 9 hereof, on collection in accordance with paragraph 5
hereof, as proceeds of insurance in accordance with paragraph 11 hereof, or
otherwise) to the payment, in whole or in part, of principal of and/or interest
on any or all of the Liabilities, whether or not then due, allocating the same
as it shall elect, making rebate of interest or discount to the extent required
by law and so as not to make the rate of interest ?pledged unlawful with respect
to the undersigned. If any Liabilities shall be contingent, the Bank may retain
a sufficient amount of the net cash receipts from the Security to cover the
largest aggregate sum which may become due or owing thereunder with prospective
interest, costs, expenses and attorneys' fees and shall not be charged with any
interest with respect thereto.

      13. Until the occurrence of an Event of Default or notice from the Bank
terminating or limiting the right of the undersigned to do so, or, in the case
of the collection, compromise, or adjustment of accounts receivable, until the
Bank takes any action pursuant to paragraph (5)(e) hereof, the undersigned may
sell or lease in the ordinary course of its regular business inventory
constituting a part of the Security and may collect, compromise and adjust
accounts receivable constituting a part of the Security, all on such terms as
the undersigned may in good faith deem advisable in the ordinary course of its
regular business, and may retain all sums so collected. Except as permitted by
this paragraph 13, the undersigned may not sell, lease, assign or otherwise
dispose of any of the Security without the prior written consent of the Bank. In
addition, the undersigned may not sell, assign or otherwise dispose of any
shares of stock or other securities now owned or hereafter acquired by the
undersigned which are issued by the same issuer and are of the same class as any
shares of stock or other securities constituting a part of the Security. The
undersigned shall keep all of the Non-Possessory Security (as described in
Schedule A hereto) at the undersigned's premises listed in Schedule A hereto and
shall not remove any of the Non-Possessory Security therefrom without the Bank's
prior written consent.

      14. In any litigation or legal proceeding arising out of, or relating to,
this agreement or any of the Liabilities or Security, in which the Bank and the
undersigned shall be adverse parties, the undersigned waives the right to
interpose any defense, set-off or counterclaim of any kind not directly arising
herefrom or therefrom, as the case may be, and also waives the right to a trial
by jury. In the event that the Bank brings any action or suit in any court of
record of New York State or the Federal Government to enforce any or all of the
Liabilities or any of the Bank's rights hereunder, service of process may be
made upon the undersigned by mailing a copy of the summons to the undersigned at
its chief executive office set forth in Schedule A hereto, and the undersigned
hereby irrevocably submits to the jurisdiction of any New York State or Federal
Court located in New York City over any action, suit or proceeding arising out
of any dispute between the undersigned and the Bank.

      15. If in its sole discretion the Bank deems it desirable, it may remove
any Security held by it from the place where it may now or hereafter be located
to any other place and deal with it there as herein provided.

      16. Upon the occurrence of an Event of Default, and at any time
thereafter, the Bank shall have and may exercise, without further notice, a
right of set-off and/or banker's lien against and in respect of any of the
Security then or thereafter held by the Bank. Any right of set-off exercised by
the Bank shall be deemed to have been exercised immediately on the occurrence of
an Event of Default, even though such set-off is made or entered on the books of
the Bank subsequent thereto.

      17. If the time for payment of principal of or interest on any of the
Liabilities or any other money payable hereunder or with respect to any of the
Liabilities is extended because said sum becomes due on a Saturday, Sunday or
public holiday, interest shall be payable for such extended time.

      18. The Bank shall not be deemed to have modified or waived any of its
rights hereunder or any terms or conditions hereof unless such modification or
waiver is in writing and signed by a duly authorized officer of the Bank. No
such modification or waiver, unless so expressly stated herein, shall be
effective as to any transaction which occurs subsequent to the date of such
modification or waiver nor shall it constitute a continuing modification or
waiver. No delay on the part of the Bank in exercising any power or right
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any power or right hereunder preclude any other or further exercise
thereof or the exercise of any other power or right. All rights and remedies of
the Bank with respect to the Liabilities or Security, whether evidenced hereby
or by any other instrument or paper, shall be cumulative and may be exercised

US$650,000.00                                                Mahwah, New Jersey

                                                              December 31, 1997


      FOR VALUE RECEIVED, George Morgenstern (the "Borrower"), hereby promises
to pay to the order of DATA SYSTEMS & SOFTWARE INC., a Delaware corporation (the
"Lender"), at the office of the Lender at 200 Route 17, Mahwah, New Jersey
07430, the principal sum of Six Hundred Fifty Thousand Dollars ($650,000.00) in
lawful money of the United States of America plus interest from the date hereof
on such principal amount hereof at the rate of 7% per annum, payable in like
funds, at said offices.

      The principal amount of this Note and interest thereon shall be payable as
follows: (i) one hundred five (105) bi-weekly payments of $3,000 each,
commencing on January 2, 1998; (ii) four (4) annual payments of $72,000 each,
commencing on December 31, 1998; and (iii) one (1) final payment of the then

      By written notice to the Borrower, this Note shall be declared immediately
due and payable in full in the event that any overdue payment of principal or
interest is not paid in full within thirty (30) days after such notice.

      The Borrower shall have the right to prepay this Note in whole or in part,
without premium or penalty. The Borrower hereby waives diligence, presentment,
demand, protest and notice of any kind whatsoever. The non-exercise by the
holder of this Note of any of its rights hereunder in any particular instance
shall not constitute a waiver thereof in that or any subsequent instance.

      This Note will be secured by a guarantee of Florence Morgenstern (the
"Guarantor") and by the recording of a mortgage lien on the Guarantor's
leasehold interest in the apartment identified in the Israel Land Registry in
Jerusalem as Parcel 6 in Block 30165, Apartment 17, Building 1 (the
"Apartment").

      The outstanding principal of this Note and all interest accrued thereon
shall be due and payable upon the sale of the Guarantor's leasehold interest in
the Apartment.

      IN WITNESS  WHEREOF,  the  undersigned has executed this Note this 31st
day of December, 1997.


                                        /s/ George Morgenstern

                                    GUARANTEE


      FOR VALUE RECEIVED, the undersigned hereby unconditionally guarantees the
punctual payment when due, at stated maturity, by acceleration or otherwise, of
all obligations now or hereafter existing of George Morgenstern under that
certain Promissory Note dated December 31, 1997 in the principal amount of Six
Hundred Fifty Thousand Dollars ($650,000.00).

      This guarantee will be secured by recording of mortgage lien on the
Guarantor's leasehold interest in the apartment identified in the Israel Land
Registry in Jerusalem, where the lease was registered in the Guarantor's name on
December 15, 1996, as Parcel 6 in Block 30165, Apartment 17, Building 1.

      The Guarantor waives notice of acceptance of this guarantee by the
Borrower and notice of presentment, demand for payment, protest and any notices
of default in the payment of the Note.

      The Guarantor represents that at the time of execution and delivery of
this Guarantee, no condition or breach of any obligation exists to impair the
effectiveness of the liability of the Guarantor to the Lender hereunder or the
immediate taking effect of this Guarantee as the sole agreement between the
Guarantor and the Lender with respect to guaranteeing the Borrower's obligations
to the Lender under the Note.

      The Guarantor waives any requirement that the Lender or its successors or
assigns, first make demand upon, or seek to enforce remedies against, the
Borrower before seeking to enforce this Guarantee.

      The whole of this Guarantee is herein set forth and there is no verbal or
other written agreement, and no understanding or custom, affecting the terms
hereof. This Guarantee may be modified only by a written instrument signed by
the party to be charged therewith.

      This Guarantee is delivered and made in, and shall be construed pursuant
to the laws of, the State of New York and is legally binding in accordance with
the terms and conditions contained herein upon the Guarantor and its legal
representatives, successors or assigns.

      IN WITNESS WHEREOF, the undersigned has executed this Guarantee this day
31st of December 1997.
