ITEM 1. BUSINESS
 
     HNC develops, markets and supports predictive software solutions for
leading service industries. These predictive software solutions employ
proprietary neural-network predictive decision engines, profiles, traditional
statistical modeling, business models, expert rules and context vectors to
convert existing data and business experiences into meaningful recommendations
and actions. Just as manufacturing organizations have implemented manufacturing
resource planning ("MRP") software to automate routine transactions, leading
service industries such as the health-care/insurance, financial services and
retail industries are using predictive software solutions to improve
profitability, competitiveness and customer satisfaction.
 
INDUSTRY BACKGROUND
 
     Today's competitive business environment has forced many service companies
to increase business efficiency while improving their flexibility and
responsiveness to changing market conditions. Businesses continually seek new
ways to make better decisions by collecting and analyzing data. Consequently,
service companies have made, and continue to make, significant investments in
computer systems designed to gather and electronically store ever increasing
amounts of data. In most cases, these computerized systems automate manual tasks
and activities, resulting in the conversion of significant amounts of corporate
data from paper to electronic form. However, these systems generally do not
synthesize data in ways that help businesses make better real-time decisions.
 
     Historically, the development of predictive software solutions was
inhibited by the lack of computing standards and effective computational
intelligence techniques. The emergence of client-server standards, including
relational database management systems, the Windows operating system and network
communications protocols, has fostered the increased transmission and
dissemination of electronically stored data within and among businesses. MRP
software systems were developed to automate production, accounting, human
resources and distribution transactions for primarily manufacturing
organizations. These systems manage and store large amounts of diverse business
information, providing continuous and simultaneous availability of information
to geographically dispersed employees, customers and suppliers. However, MRP
systems generally do not provide businesses with the functionality and
flexibility needed to utilize this data to simulate operations and make
real-time decisions and recommendations in diverse and rapidly changing business
environments.
 
     Several service industries have a particular need to leverage large volumes
of real-time transactional and operational data in order to address systemic
issues that have historically affected profitability, competitiveness and
customer satisfaction. These industries and issues include:
 
     - HEALTHCARE/INSURANCE INDUSTRY. Workers' compensation fraud and abuse is
       currently receiving widespread attention in the healthcare/insurance
       industry. Conning & Co. recently estimated that 10%-25% of the dollar
       amount of filed workers' compensation claims in the United States are
       fraudulent. This translates to more than $5 billion lost each year to
       workers' compensation fraud.
 
     - FINANCIAL SERVICES INDUSTRY. Based on reports from Visa and Mastercard,
       Faulkner & Gray estimates that United States credit card credit losses
       and chargeoffs were $18 billion in 1996.
 
     - RETAIL INDUSTRY. Rapid changes in consumer buying patterns have caused
       merchants to place increased emphasis on predicting consumer demand and
       managing retail inventories. The change from mass to individual retail
       marketing has multiplied the number of promotional offers and
       stock-keeping units ("SKUs") required to address market opportunities.
       The U.S. Department of Commerce estimates that the inventory carrying
       costs for retail inventories nationwide were $316 billion at the end of
       March 1997.
 
     Historically, many companies in the healthcare/insurance, financial
services and retail industries have developed specialized in-house applications
to address these issues. Such applications are generally designed to access
large volumes of operational and transactional data stored on mainframe
computers. However, such
 
                                        3
<PAGE>   4
 
systems are expensive, costly to support and maintain, and do not offer flexible
and enterprise-wide access to data. Furthermore, most of these systems are not
designed to meet the need for real-time recommendations and actions. The
widespread adoption of distributed client-server computing has provided
organizations with a much greater ability to access and manipulate stored
information but also has created the need for third-party vendors of packaged
applications software solutions that provide the same degree of functionality
and reliability as traditional in-house applications. These vendors are able to
provide a higher degree of functionality and reliability than traditional
in-house applications by combining the domain knowledge from their customers and
partners with expertise in computational intelligence and client-server
technologies.
 
THE HNC SOLUTION
 
     HNC's predictive software solutions enable leading service industries, such
as the healthcare/insurance, financial services and retail industries, to
analyze and act upon operational and transactional data in real time. The
Company's products provide the following benefits:
 
   
     Core predictive software technology. The Company's software includes a
variety of computational intelligence technologies such as proprietary
neural-network predictive decision engines, profiles, traditional statistical
modeling, business models, expert rules and context vectors, that can be
customized to specific business applications. Neural networks can be adapted to
changing environments and applications quickly and have proven to be accurate
and effective in real-time operating environments. The Company's decision engine
also includes a user-defined rule-based technology. The neural networks and
rulebases are delivered through software that allows the Company's products to
adapt to many customer-specific business needs without extensive custom
programming. Adaptable functions include workflow queuing management, policy and
procedure guidelines, input data modification, flexible graphical user interface
("GUI") display, decision criteria and report formats.
    
 
     Quick payback for customers. The Company's software solutions are designed
for quick customer payback. The Company typically installs its products in two
to six months, and customer payback periods for installation and first year
usage fees are typically less than one year. Payback is rapid because the
software products address applications that have a significant profit impact.
HNC personnel focus not only on the technical integration, but also on
delivering direct benefits to the customer throughout the service contract
period.
 
   
     Transaction-based, real-time decision capability. HNC's software can
operate in real time, providing an immediate, situation-specific response to
each customer transaction. For example, the Falcon system for credit/debit card
fraud detection can monitor millions of transactions each day, identify
fraudulent transactions in progress and permit the card issuing bank to withhold
an authorization before the perpetrator completes a purchase. The Falcon system
differs from traditional modeling implementations, which operate in a batch or
off-line mode on a collection of historical transactions.
    
 
     Flexible client-server solutions. HNC's solutions can be integrated into a
customer's existing environment or architecture. The Company's products are
available on industry-standard, client-server platforms, including Windows and
UNIX clients, NetWare, Windows NT, UNIX and CICS servers and IBM, Oracle, Sybase
and Informix databases. HNC's application products represent a complete software
solution, including decision models, deployment software, communications
interfaces and GUIs. The Company also supplies systems integration, ongoing
performance analysis, model rebuilding and application consulting services to
help ensure ongoing success for the customer. The Company believes that this
flexible combination of products, services and deployment platforms represents
an advance that enables successful predictive software system deployment in many
mission-critical applications.
 
     Turnkey, customized and user-developed model options. The choice of data
source is important to customers because data are the fundamental building
blocks used to create accurate predictive models. HNC provides various models
built on industry-specific or customer-specific data to meet individual
application requirements. Customers and data suppliers provide the Company with
historical transaction data for turnkey models, trend analyses and product
updates. This combination of proprietary turnkey (from data and
 
                                        4
<PAGE>   5
 
individual consumer profiles), customized and user-developed models allows the
Company to offer products that solve a broad range of predictive application
problems.
 
HNC'S STRATEGY
 
     HNC's objective is to be the leading supplier of predictive software
solutions by leveraging its core computational intelligence technology across a
series of product families targeted at specific service industries. The
Company's strategy for achieving this objective contains the following key
elements:
 
   
     Maintain and strengthen HNC's position at the core of its customers'
applications infrastructure. Customers rely heavily on HNC's predictive software
solutions to anticipate and react to rapidly changing business conditions. The
Company's core computational intelligence technology serves as a platform upon
which service businesses can deploy and combine the Company's products to manage
and respond to operational and transactional data in real time. Therefore, HNC
attempts to establish a strong position within the applications infrastructure
of its customers. For example, the Company's first predictive solution product,
Falcon, is a credit/debit card fraud detection system for monitoring individual
credit card accounts. By adapting the core technology developed for Falcon, the
Company later introduced ProfitMax, a transaction-based, real-time credit
authorization system that manages the profitability of credit card portfolios.
The Company believes that the opportunity exists for similar penetration within
each of its core vertical markets, including opportunities such as retail
banking within the financial services industry. As another example, the
Company's context vectoring technology could profile visitors to a financial
institution's Web site and send proactive direct e-mails regarding financial
products.
    
 
   
     Leverage core predictive technologies to enter new market segments.
Historically, the Company has applied its core predictive technology to the
domain knowledge of companies it has acquired to introduce new products. For
example, in August 1996, HNC acquired Risk Data Corporation ("Risk Data"), a
developer of decision systems in the workers' compensation industry. By
combining Risk Data's industry expertise with HNC's fraud detection technology,
HNC is developing a VeriComp module that applies predictive technology to
employer fraud in the workers' compensation industry. In addition, the Company
is evaluating opportunities in other data-intensive industries, such as
telecommunications, where predictive software may have the ability to improve
business performance and profitability.
    
 
     Earn recurring revenues through long-term contracts. The Company markets
most of its predictive software solutions as an ongoing service that includes
software licenses, decision model updates, application consulting and on-line or
on-site support and maintenance. Since many of the Company's applications are
enhanced by periodic model updates, customers derive significant value from the
Company's ongoing services. In addition, the mission-critical nature of many of
HNC's predictive software solutions creates customer demand for long-term
support commitments. Accordingly, the Company's customers typically pay for this
package of software and service with a monthly usage fee and a three to seven
year contract commitment.
 
     Use strategic relationships to support direct distribution. In each of its
primary markets, the Company uses strategic relationships with system
integrators and third-party service providers to support its direct distribution
efforts. These partners provide varying levels of distribution support, from
lead generation to resale of the Company's products. The Company maintains such
strategic relationships with Electronic Data Systems ("EDS"), Intracorp and
Marsh McLennan, Inc. in healthcare/insurance, First Data and EDS in financial
services, and Andersen Consulting and KPMG Peat Marwick LLP in retail.
 
   
     Growth through acquisitions. The Company acquired Risk Data, Retek
Distribution Corporation, now known as Retek Information Systems ("Retek") and
CompReview, Inc. ("CompReview") in 1996 and 1997, thereby significantly
expanding its product offerings in its target markets. On January 30, 1998, the
Company signed a definitive agreement to acquire Practical Control Systems
Technologies, Inc. ("PCS"), a distribution center management software vendor
based in Cincinnati, Ohio, subject to the satisfaction of certain closing
conditions and the approval of PCS' shareholders. The Company expects to
continue to review acquisitions of businesses, products and technologies as a
means to expand its product offerings for existing and new target markets.

  Retail
 
     Although retailers have made significant investments in customer
information, point-of-sale and quick-response ordering systems, these
applications often do not include the forecasting ability required to maximize
profitability and respond to competition through timely "in-store"
replenishment, electronic networking and quick response initiatives. HNC has
developed a group of products that effectively addresses inventory control,
merchandise management and financial control management. These software
solutions allow retailers to build forecasting and marketing models to carry out
day-to-day buying and selling activities, thereby reducing carrying costs for
inventories and improving purchasing, promotion and logistics efficiencies. The

EMERGING MARKET OPPORTUNITIES
 
     The Company's experience and technology capabilities in the
healthcare/insurance, financial services and retail markets often lead to new
product ideas and concepts. The Company also evaluates new market opportunities
that arise through its commercial and government contract work. As contracts are
completed, the end products are evaluated for commercialization. For example,
contracts for the Advanced Research Projects Agency, United States Army Research
Laboratory, United States Air Force, Office of Naval Research, DataTimes
Corporation and Tracor Applied Sciences, Inc. generated a context-based text
analysis technology called MatchPlus. This core text analysis technology has
been under development at HNC for the last four years for Department of Defense
applications. During 1996, the Company formed Aptex to commercialize HNC's
MatchPlus text analysis technology for emerging markets. Aptex has developed a
strategic partnership with InfoSeek Corporation, an Internet search and
navigation service, to deliver products using this text analysis technology to
the Internet market. To date, three new Internet products have been launched:
SelectCast, SelectResponse and SelectResource.
 
     Substantially all of the Company's revenues in recent years have been
attributable to sales of predictive software solutions and services, and these
products and services are currently expected to continue to account for a
substantial amount of the Company's future revenues. The market for predictive
software solutions is still emerging. The rate at which businesses have adopted
the Company's products has varied significantly by market and by product within
each market, and the Company expects to continue to experience such variations
with respect to its target markets and products in the future. The Company has
introduced products for the healthcare/insurance, financial services and retail
markets. The Company has recently announced several new products, including
PMAdvisor, VeriComp, SelectCast, SelectResponse and SelectResource. To date,
none of these products has achieved any significant degree of market acceptance,
and there can be no assurance that such products will ever be widely accepted.
Although businesses in the Company's target markets have recognized the
advantages of using predictive software solutions to automate the decision-
making process, many have developed decision automation systems internally
rather than licensing them from outside vendors. There can be no assurance that
the markets for the Company's products will continue to develop or that the
Company's products will be widely accepted, if at all. If the markets for the
Company's new or existing products fail to develop, or develop more slowly than
anticipated, the Company's sales would be negatively impacted, which would have
a material adverse effect on the Company's business, financial condition and
results of operations.

CUSTOMER SERVICE AND SUPPORT
 
     A high level of continuing maintenance, service and support is critical to
maintaining the performance of the Company's predictive software solutions.
Service and support are also essential to the Company's objective of developing
long-term relationships with, and obtaining recurring revenues from, customers.
The Company's service and support activities are related to system installation,
performance validation and ongoing consultation on the optimal use of HNC
products.
 
     Model and Rule Updates. Most HNC product license agreements include
periodic data, model and/or rule updates to maintain system performance. HNC
technical personnel generally assist the customer with installation of updates.
The Company makes commitments to update models and rules at varying intervals,
from fixed times (such as quarterly and annually) to unscheduled times, provided
the customer has met its commitments to provide data to HNC.
 
     Education. The Company offers comprehensive education and training programs
to its customers. The Company provides on-site training services associated with
many of its products. Fees for education and training services are generally
included in usage-priced products, but may be charged separately in other cases.
 
     Consulting. The Company's consultants are available to work with customers'
user application groups and information systems organizations. Customers that
buy consulting services are usually planning large implementations or want to
optimize performance of the Company's products in their operating environments.
Fees for consulting are generally included in usage-priced products, but may be
charged separately in other cases.
 
PRICING
 
   
     The Company generally establishes prices in one of two ways: usage-based
fees and fixed-fee licenses with maintenance. The Company generally employs
usage-based pricing for its healthcare/insurance products, Falcon, ProfitMax and
AREAS. Under the usage-based pricing structure, HNC generally provides a fixed-
term software license, software maintenance, model updates (in the case of
HNC-supplied models) and ongoing consulting services in exchange for recurring
revenue based on usage. Usage-based term contracts typically include annual
price index adjustments. In 1995, 1996 and 1997, annual license and maintenance
revenues from these contracts represented 61.2%, 56.1% and 55.2% of the
Company's total revenues, respectively. The Company generally employs fixed-fee
license pricing for Capstone and all of the Company's retail products except
Falcon Retail. Under the fixed-fee license pricing structure, the Company
generally licenses the product for the customer's internal use on a perpetual
basis. In most cases, the user can separately contract for maintenance services
on an annual basis. The Company typically offers early adopter pricing for its
usage-based products to customers that agree to be part of pilot or other early
product life cycle installations. Early adopter pricing might include
reduced-fee perpetual licenses, reduced-fee services or both.
    
 
     The Company often contracts for installation services associated with its
predictive software solutions. The Company provides user-specific proposals
priced at either fixed-fee levels or on a time and materials basis. In nearly
all cases, travel expenses are billed separately at cost.
 
     The Company offers contract consulting services. Because of the complexity
associated with predictive software solutions, users often request that HNC help
them to develop models or analyze problems. Also, the Company from time to time
accepts engagements not associated with current product offerings in order to
become more familiar with a new application area and determine the potential for
new product development. Although consulting services are included with many of
the Company's usage-based products, customers may request additional consulting,
often associated with custom modeling.
 
SALES AND MARKETING
 
     The Company sells and markets its software and services in North America
and internationally through its direct sales organization, joint marketing and
distribution agreements. The Company's worldwide sales and marketing
organization consisted of 125 employees as of December 31, 1997. The domestic
sales staff is based at the Company's corporate headquarters in San Diego and in
United States field offices in California,
 
                                        9
<PAGE>   10
 
Colorado, Connecticut, Georgia, Minnesota, New York, Pennsylvania, Texas and
Virginia. Internationally, the Company has field sales offices in Australia,
Canada, France, Germany, Japan, Singapore, South Africa and the United Kingdom.
To support its sales force, the Company conducts comprehensive marketing
programs, which include direct mail, public relations, advertising, seminars,
trade shows and ongoing customer communication programs. The sales staff is
generally product-based, and each representative is assigned a geographic
territory.
 
   
     The Company has licensed First Data Resources, Inc. ("First Data") and EDS
to act as service bureaus to provide an alternate channel of distribution for
end-users to utilize the Falcon product to process credit card receipts for
banks and other credit card issuers. The Company generally assists its service
bureau partners in the sales effort, often employing the Company's direct sales
force in the process. Company sales representatives earn a commission for
service bureau sales in their territory. These service bureaus pay the Company
monthly usage fees based on the volume of transactions processed for such credit
card issuers. Product licenses to First Data, the largest provider of credit
card charge receipt processing services to banks, accounted for 8.7%, 8.6% and
7.6% of the Company's total revenues in 1995, 1996 and 1997, respectively. The
Company has licensed First Data to provide its customers with access to the
Company's ProfitMax product pursuant to a license agreement entered into in
January 1996 (the "ProfitMax Contract"). The Company's revenues under the
ProfitMax Contract represented approximately one-quarter of the Company's
revenues from First Data in 1997. In late January 1998, First Data asserted that
certain restrictive covenants under the ProfitMax Contract violated certain
intellectual property laws. First Data also asserted that the existence of such
restrictions made the ProfitMax Contract at least temporarily unenforceable and
that First Data is therefore not obligated to pay the Company license fees due
under the ProfitMax Contract. The Company disputed First Data's claim, released
and waived the above-mentioned restrictive covenants in the ProfitMax Contract
and gave First Data written notice that the Company intended to terminate the
ProfitMax Contract pursuant to its terms unless First Data cured its failure to
pay the delinquent license fees in a timely manner. Currently, First Data and
the Company are working to resolve their dispute regarding the ProfitMax
Contract by negotiating a new agreement. First Data has resumed making license
fee payments on a delayed basis, and HNC has agreed to extend the date for First
Data to pay past due license fees until mid-April 1998. Although HNC expects to
reach a new agreement with First Data that will resolve the pending dispute,
there can be no assurance that such an agreement will be reached or that the
terms of such an agreement would be as favorable to HNC as its existing
contractual arrangements with First Data. If no such agreement can be reached
and First Data maintains its current position, it is possible that litigation or
arbitration could ensue, which would likely result in a loss of anticipated
revenue to the Company under the ProfitMax Contract and possibly other
agreements between the Company and First Data, which could have a material
adverse effect on the Company's business, financial condition and results of
operation.
    
 
     The Company also uses representative agents for certain products in certain
territories outside of North America. The Company has agents covering Australia,
Austria, France, Germany, Italy, New Zealand, Spain and Switzerland. In 1995,
1996 and 1997, international operations and export sales (includes sales in
Canada) represented 12.6%, 17.7% and 16.8% of the Company's total revenues,
respectively. International sales result primarily from Falcon product sales and
sales of retail products. The Company intends to continue to expand its
operations outside the United States and to enter additional international
markets, including by adding sales and support offices in Europe and Japan,
which will require significant management attention and financial resources. The
Company has committed and continues to commit significant time and development
resources to customizing certain of its products for selected international
markets and to developing international sales and support channels. There can be
no assurance that the Company's efforts to develop products, databases and
models for targeted international markets or to develop additional international
sales and support channels will be successful. The failure of such efforts,
which can entail considerable expense, could have a material adverse effect on
the Company's business, financial condition and results of operations. See "Risk
Factors -- Risks Associated with International Sales."
 
     International sales are subject to additional inherent risks, including
longer payment cycles, unexpected changes in regulatory requirements, import and
export restrictions and tariffs, difficulties in staffing and managing foreign
operations, the burdens of complying with a variety of foreign laws, greater
difficulty or delay
 
                                       10
<PAGE>   11
 
in accounts receivable collection, potentially adverse tax consequences and
political and economic instability. The Company's international sales are
currently denominated predominantly in United States dollars and a small portion
are denominated in British pounds sterling. An increase in the value of the
United States dollar relative to foreign currencies could make the Company's
products more expensive, and therefore potentially less competitive, in foreign
markets. In the future, to the extent the Company's international sales are
denominated in local currencies, foreign currency translations may contribute to
significant fluctuations in the Company's business, financial condition and
results of operations. If for any reason exchange or price controls or other
restrictions on foreign currencies are imposed, the Company's business,
financial condition and results of operations could be materially adversely
affected.
 
     Due in part to the mission-critical nature of certain of the Company's
applications, potential customers perceive high risk in connection with adoption
of the Company's products. As a result, customers have been cautious in making
decisions to acquire the Company's products. In addition, because the purchase
of the Company's products typically involves a significant commitment of capital
and may involve shifts by the customer to a new software and/or hardware
platform, delays in completing sales can arise while customers complete their
internal procedures to approve large capital expenditures and test and accept
new technologies that affect key operations. For these and other reasons, the
sales cycle associated with the purchase of the Company's products is typically
lengthy, unpredictable and subject to a number of significant risks over which
the Company has little or no control, including customers' budgetary constraints
and internal acceptance reviews. The sales cycle associated with the licensing
of the Company's products can typically range from 60 days to 18 months. As a
result of the length of the sales cycle and the typical size of customers'
orders, the Company's ability to forecast the timing and amount of specific
sales is limited. A lost or delayed sale could have a material adverse effect on
the Company's business, financial condition and results of operations.
 
TECHNOLOGY
 
     The Company seeks to develop innovative products by combining industry and
application knowledge with its core neural-network technology to address
specific market needs. The Company's systems also employ rule-based technology
to implement customer strategy, policy and procedures. These technologies are
incorporated in computer software and hardware architectures, including
client-server hardware, relational databases and object-oriented programming.
The Company intends to continue to develop state-of-the-art technologies to
enhance its current products and broaden development opportunities.
 
     Neural-Network Technology. Neural networks have predictive power that can
be improved with experience as the historical database increases in size. The
term "neural network" refers to a family of nonlinear, statistical modeling
techniques, sometimes called "computational intelligence." These techniques
distinguish themselves through a process of automated "learning" or "training"
that replaces the time-consuming manual techniques of traditional nonlinear,
statistical modeling. The neural-network architecture itself consists of groups
of "processing elements," or equations with several inputs and a single output.
The output of each element becomes either the input to another element or part
of the dependent output. Each input receives a "weight" or value, in the
equation, which is adjusted during the training process. The actual result from
each training record is compared with the answer from the neural network, and
the weights are adjusted to reduce the error between the two. This process can
become computationally intensive, as millions of training data records must be
processed hundreds or thousands of times. HNC has developed proprietary
high-speed and parallel-processor boards to accelerate training and execution of
its neural-network software. The Company believes that the rapid model
development afforded by its technology provides a competitive advantage in the
development of predictive software solutions.
 
     Rule-Based Technology. The Company's systems also employ rule-based
technology to implement customer strategy, policy and procedures. The rules are
implemented as part of predictive processes. The Company believes that its
combination of neural networks and rule bases in a single decision engine
represents a significant competitive advantage over more traditional approaches
to decision automation.
 
     Context Vector Technology. Context vector technology that originated at HNC
and is being commercialized at Aptex is a way to explore, analyze and model
unstructured textual data. Context vector technology
 
                                       11
<PAGE>   12
 
automatically discovers the underlying structure of free form symbolic data.
This structure enables modeling from data elements previously considered
impossible to include in predictive software applications. Context vector
technology also models behavior. Just as relationships are discovered in
unstructured data, observing electronic transaction behavior identifies
patterns. Compatibility predictions can be made between information, behavior,
people and products. When combined with other HNC technologies, such as neural
networks and rule-based systems, the Company believes that context vectors can
improve the performance of existing applications while opening new market
opportunities. Context vector technology has been demonstrated to increase
banner advertising click rates on the Internet, automate e-mail responses and
discover unknown relationships in credit card transaction data.
 
     The Company's success depends upon its ability to enter new markets by
successfully developing new products for such markets on a timely and
cost-effective basis. The Company's products often require customer data for
decision model development and system installation. As a result, completion of
new products (particularly new products for markets not previously served by the
Company) may be delayed while the Company extracts sufficient amounts of
statistically relevant data and develops the models. During this development
process, the Company relies on its potential customers in the new market to
provide data and to help train Company personnel in the use and meaning of the
data in the specific industry. These relationships also assist the Company in
establishing a market presence and credibility in the new market. These
potential customers, most of which have significantly greater financial and
marketing resources than the Company, may compete with the Company in the future
or otherwise discontinue their relationships with or support of the Company,
either during development of the Company's products or thereafter. The failure
by the Company to obtain adequate third-party support for new product
development would have a material adverse effect on the Company's ability to
enter new markets and, consequently, on the Company's business, financial
condition and results of operations. See "Risk Factors -- Risks Associated with
Technological Change and Delays in Developing New Products."
 
RESEARCH AND DEVELOPMENT
 
     The Company believes that its future success depends in part on its ability
to maintain and improve its core technologies, enhance its existing products and
develop new products that meet an expanding range of markets and customer
requirements. The Company intends to expand its existing product offerings and
to introduce new predictive software solutions. In the development of new
products and enhancements to existing products, the Company uses its own tools
extensively. Until 1996, the Company relied primarily on internal development of
its products. Based on timing and cost considerations, however, the Company has
acquired, and in the future may consider acquiring, technology or products from
third parties. For example, the Company acquired technology and products in
connection with its acquisitions of Risk Data and Retek in 1996 and CompReview
in 1997.
 
     The Company performs all quality assurance and develops documentation
internally. The Company intends to continue to support industry standard
operating environments, client-server architectures and network protocols. The
Company's specialists in neural network model development, software engineering,
user interface design, product documentation and quality improvement are
responsible for maintaining and enhancing the performance, quality and usability
of all HNC predictive software solutions. The marketing services organization is
responsible for authoring and updating all user documentation and other
publications. See "Risk Factors -- Risks Associated with Technological Change
and Delays in Developing New Products."
 
     The Company strategically targets its long-term research projects. In
addition to funds allocated by the Company for research, HNC receives research
contracts from a range of commercial sources and the United States Government.
Government and commercial contract customers have included the Advanced Research
Projects Agency, United States Air Force, Office of Naval Research and Tracor
Applied Sciences, Inc. The Company believes that these contracts augment its
ability to maintain existing technologies and investigate new technologies that
may or may not become part of its products. The United States Government
typically retains certain intellectual property rights and licenses in the
technologies the Company develops under research contracts directly or
indirectly sponsored by the government, and in some cases can terminate the
Company's rights in such technologies if the Company fails to commercialize them
on a timely basis.
 
                                       12
<PAGE>   13
 
Historically, these contracts have not resulted in development of products
contributing to the Company's revenues in the fiscal year in which the research
contract is performed, or in the subsequent fiscal year.
 
     The market for the Company's predictive software solutions for service
industries is characterized by rapidly changing technology and improvements in
computer hardware, network operating systems, programming tools, programming
languages, operating systems and database technology. The Company's success will
depend upon its ability to continue to develop and maintain competitive
technologies, enhance its current products and develop, in a timely and
cost-effective manner, new products that meet changing market conditions,
including evolving customer needs, new competitive product offerings, emerging
industry standards and changing technology. For example, the rapid growth of the
Internet environment creates new opportunities, risks and uncertainties for
businesses, such as the Company, which develop software solutions that now may
have to be designed to operate in Internet, intranet and other on-line
environments. The Company may not be able to develop and market, on a timely
basis, or at all, product enhancements or new products that respond to changing
technologies. The Company has previously experienced significant delays in the
development and introduction of new products and product enhancements, primarily
due to difficulties with model development, which has in the past required
multiple iterations, as well as difficulties with acquiring data and adapting to
particular operating environments. The length of these delays has varied
depending upon the size and scope of the project and the nature of the problems
encountered. Any significant delay in the completion of new products, or the
failure of such products, if and when installed, to achieve any significant
degree of market acceptance, would have a material adverse effect on the
Company's business, financial condition and results of operations. Any failure
by the Company to anticipate or to respond adequately to changing technologies,
or any significant delays in product development or introduction, could cause
customers to delay or decide against purchases of the Company's products and
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
     The Company relies on a combination of patent, copyright, trademark and
trade secret laws and confidentiality procedures to protect its proprietary
rights. The Company currently owns seven issued United States patents and has
four United States patent applications pending. The Company has applied for
additional patents for its Falcon technology in Canada, Europe and Japan and for
its MIRA product in Australia, Canada and Europe. There can be no assurance that
patents will be issued with respect to pending or future patent applications or
that the Company's patents will be upheld as valid or will prevent the
development of competitive products. The Company seeks to protect its software,
documentation and other written materials under trade secret and copyright laws,
which afford only limited protection. As part of its confidentiality procedures,
the Company generally enters into invention assignment and proprietary
information agreements with its employees and independent contractors and
nondisclosure agreements with its distributors, corporate partners and
licensees, and limits access to and distribution of its software, documentation
and other proprietary information. Despite these precautions, it may be possible
for a third party to copy or otherwise to obtain and use the Company's products
or technology without authorization, or to develop similar technology
independently. In addition, to ensure that customers will not be adversely
affected by an interruption in the Company's business, the Company places source
code for certain of its products into escrow, which may increase the likelihood
of misappropriation or other misuse of the Company's intellectual property.
Moreover, effective protection of intellectual property rights may be
unavailable or limited in certain foreign countries in which the Company has
done and may do business. Also, the Company has developed technologies under
research projects conducted under agreements with various United States
Government agencies or subcontractors to such agencies. Although the Company has
acquired certain commercial rights to such technologies, the United States
Government typically retains ownership of certain intellectual property rights
and licenses in the technologies developed by the Company under such contracts,
and in some cases can terminate the Company's rights in such technologies if the
Company fails to commercialize them on a timely basis. In addition, under
certain United States Government contracts, the results of the Company's
research may be made public by the government, which could limit the Company's
competitive advantage with respect to future products based on such research.
 
                                       13
<PAGE>   14
 
     In the past, the Company has received communications from third parties
asserting that Company trademarks infringe such other parties' trademarks, none
of which has resulted in litigation or losses to the Company. Given the
Company's ongoing efforts to develop and market new technologies and products,
the Company may receive communications from third parties asserting that the
Company's products infringe, or may infringe, their intellectual property
rights. If as a result of any such claims the Company were precluded from using
certain technologies or intellectual property rights, licenses to such disputed
third-party technology or intellectual property rights might not be available on
reasonable commercial terms, if at all. Furthermore, the Company may initiate
claims or litigation against third parties for infringement of the Company's
proprietary rights or to establish the validity of the Company's proprietary
rights. Litigation, either as plaintiff or defendant, could result in
significant expense to the Company and divert the efforts of the Company's
technical and management personnel from productive tasks, whether or not such
litigation is resolved in favor of the Company. In the event of an adverse
ruling in any such litigation, the Company might be required to pay substantial
damages, discontinue the use and sale of infringing products, expend significant
resources to develop non-infringing technology or obtain licenses to infringing
technology, and the court might invalidate the Company's patents, trademarks or
other proprietary rights. In the event of a successful claim against the Company
and the failure of the Company to develop or license a substitute technology,
the Company's business, financial condition and results of operations would be
materially and adversely affected.
 
     As the number of software products increases and the functionality of these
products further overlaps, the Company believes that software developers may
become increasingly subject to infringement claims. Any such claims, with or
without merit, can be time consuming and expensive to defend and could
materially and adversely affect the Company's business, financial condition and
results of operations.
 
COMPETITION
 
   
     The market for predictive software solutions for service industries is
intensely competitive and subject to rapid change. Competitors, many of which
have substantially greater financial resources than the Company, vary in size
and in the scope of the products and services they offer. The Company encounters
competition from a number of sources, including (i) other application software
companies, (ii) management information systems departments of customers and
potential customers, including banks, insurance companies and retailers, (iii)
third party professional services organizations, including without limitation,
consulting divisions of public accounting firms, (iv) hardware suppliers that
bundle or develop complementary software, (v) network and service providers that
seek to enhance their value-added services, (vi) neural-network tool suppliers
and (vii) managed care organizations. In the healthcare/insurance market, the
Company has experienced competition primarily from National Council on
Compensation Insurance ("NCCI"), Corporate Systems and CSC Incorporated. In the
workers' compensation and medical cost administration market, the Company has
experienced competition from MediCode, Inc. ("MediCode"), Medata, Inc. and
Embassy Software with regard to software licensing, and Intracorp and Corvel
Corporation in the service bureau operations market. Additionally, the Company
has faced competition from Automatic Data Processing, Inc. ("ADP") in the
automobile accident medical claims market. In the financial services market, the
Company has experienced competition from Fair, Isaac & Co., Inc., Cogensys (a
subsidiary of Policy Management Systems Corporation), Federal National Mortgage
Association ("Fannie Mae"), Federal Home Loan Mortgage Corporation ("Freddie
Mac"), International Business Machines Corporation ("IBM"), Nestor, Inc.,
NeuralTech Inc., Neuralware Inc., PMI Mortgage Services Co., VISA International
and others. In the retail market, the Company has experienced competition from
JDA Software Group, Inc., SAP AG, PeopleSoft, Inc., IBM, Manugistics Group, Inc.
and others. The Company expects to experience additional competition from other
established and emerging companies, as well as other technologies. For example,
the Company's Falcon product competes against other methods of preventing credit
card fraud, such as card activation programs, credit cards that contain the
cardholder's photograph, smart cards and other card authorization techniques.
Increased competition, whether from other products or new technologies, could
result in price reductions, fewer customer orders, reduced gross margins and
loss of market share, any of which could materially adversely affect the
Company's business, financial condition and results of operations.

     The Company believes that most of its products are currently priced at a
premium when compared to its competitors' products. The market for the Company's
products is highly competitive, and the Company expects that it will face
increasing pricing pressures from its current competitors and new market
entrants. In particular, increased competition could reduce or eliminate such
premiums and cause further price reductions. In addition, such competition could
adversely affect the Company's ability to obtain new long-term contracts and
renewals of existing long-term contracts on terms favorable to the Company. Any
reduction in the price of the Company's products could materially adversely
affect the Company's business, financial condition and results of operations.
 
     The Company believes that the principal competitive factors affecting its
market include technical performance (for example, accuracy in detecting credit
card fraud or evaluating workers' compensation claims), access to unique
proprietary databases and product attributes such as adaptability, scalability,
ability to integrate with products produced by other vendors, functionality,
ease-of-use, product reputation, quality, performance, price, customer service
and support, the effectiveness of sales and marketing efforts and Company
reputation. Although the Company believes that its products currently compete
favorably with respect to such factors, there can be no assurance that the
Company can maintain its competitive position against current and potential
competitors, especially those with significantly greater financial, marketing,
service, support, technical and other resources.
 
     Some of the Company's current, and many of the Company's potential,
competitors have significantly greater financial, technical, marketing and other
resources than the Company. As a result, they may be able to respond more
quickly to new or emerging technologies and changes in customer requirements or
to devote greater resources to the development, promotion and sale of their
products than the Company. In addition, current and potential competitors have
established or may establish cooperative relationships among themselves or with
third parties to increase the ability of their products to address the needs of
the Company's prospective customers. Accordingly, it is possible that new
competitors or alliances among competitors may emerge and rapidly gain
significant market share. Also, the Company relies upon its customers to provide
data, expertise and other support for the ongoing updating of the Company's
models. The Company's customers, most of which have significantly greater
financial and marketing resources than the Company, may compete with the Company
in the future or otherwise discontinue their relationships with or support of
the Company. There can be no assurance that the Company will be able to compete
successfully against current and future competitors or that competitive
pressures faced by the Company will not materially adversely affect its
business, financial condition and results of operations.
 
EMPLOYEES
 
     As of December 31, 1997, the Company had 706 employees, including 316 in
product development and support, 87 in customer service, 125 in sales and
marketing and 178 in finance, administration and MIS. Most of these employees
are located in the United States. None of the Company's employees are
represented by a labor union. The Company has experienced no work stoppages and
believes that its employee relationships are generally good.
 
     The Company's success depends to a significant degree upon the continued
service of members of the Company's senior management and other key research,
development, sales and marketing personnel. Accordingly, the loss of any of the
Company's senior management or key research, development, sales or marketing
personnel could have a material adverse effect on the Company's business,
financial condition and results of operations. Only a small number of employees
have employment agreements with the Company, and there can be no assurance that
such agreements will result in the retention of these employees for any
significant period of time. In addition, the untimely loss of a member of the
management team or a key employee of a business acquired by the Company could
have a material adverse effect on the Company's business, financial condition
and results of operations, particularly if such loss occurred before the Company
has had adequate time to familiarize itself with the operating details of that
business. In the past, the Company has experienced difficulty in recruiting a
sufficient number of qualified sales and technical employees. In addition,
competitors may attempt to recruit the Company's key employees. There can be no
assurance that the Company will be successful in attracting, assimilating and
retaining such personnel. The
 
                                       15
<PAGE>   16
 
failure to attract, assimilate and retain key personnel could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Risk Factors -- Risks Associated with Managing Growth."
 
   
     POTENTIAL FLUCTUATIONS IN OPERATING RESULTS. The Company's revenues and
operating results have varied significantly in the past and may do so in the
future. Because the Company's expense levels are based in part on its
expectations regarding future revenues and in the short term are fixed to a
large extent, the Company may be unable to adjust its spending in time to
compensate for any unexpected revenue shortfall. Factors affecting operating
results include market acceptance of the Company's products; the relatively
large size and small number of customer orders that may be received during a
given period; customer cancellation of long-term contracts yielding recurring
revenues or customers' ceasing their use of Company products for which the
Company's fees are usage based; the length of the Company's sales cycle; the
Company's ability to develop, introduce and market new products and product
enhancements; the timing of new product announcements and introductions by the
Company and its competitors; changes in the mix of distribution channels;
changes in the level of operating expenses; the Company's ability to achieve
progress on percentage-of-completion contracts; the Company's success in
completing certain pilot installations for contracted fees; competitive
conditions in the industry; domestic and international economic conditions; and
market conditions in the Company's targeted markets. In addition, as a result of
recently issued guidance on software revenue recognition, license agreements
entered into during a quarter may not meet the Company's revenue recognition
criteria. Therefore, even if the Company meets or exceeds its forecast of
aggregate licensing and other contracting activity, it is possible that the
Company's revenues would not meet expectations. Furthermore, the Company's
operating results may be affected by factors unique to certain of its product
lines. For example, the Company derives a substantial and increasing portion of
its revenues from its retail products, which are generally priced as "perpetual"
license transactions in which the Company receives a one-time license fee. The
Company recognizes these fees as revenue upon delivery of the software and
acceptance by the customer. Thus, failure to complete a perpetual license
transaction during a fiscal quarter would have a disproportionate adverse impact
on the Company's operating results for that quarter.
    
 
     The Company expects fluctuations in its operating results to continue for
the foreseeable future. Accordingly, the Company believes that period-to-period
comparisons of its financial results should not be relied upon as an indication
of future performance. The Company may not be able to maintain profitability on
a quarterly or annual basis in the future. Due to all of the foregoing factors,
it is possible that in some future quarter the Company's operating results will
be below the expectations of public market analysts and investors. In that
event, the price of the Company's Common Stock and, in turn, the market price of
the Notes, would likely be materially adversely affected. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
     LENGTHY AND UNPREDICTABLE SALES CYCLE. Due in part to the mission-critical
nature of certain of the Company's applications, potential customers perceive
high risk in connection with adoption of the Company's products. As a result,
customers have been cautious in making decisions to acquire the Company's
products. In addition, because the purchase of the Company's products typically
involves a significant commitment of capital and may involve shifts by the
customer to a new software and/or hardware platform, delays in completing sales
can arise while customers complete their internal procedures to approve large
capital expenditures and test and accept new technologies that affect key
operations. For these and other reasons, the sales cycle associated with the
purchase of the Company's products is typically lengthy, unpredictable and
subject to a number of significant risks over which the Company has little or no
control, including customers' budgetary constraints and internal acceptance
reviews. The sales cycle associated with the licensing of the Company's products
can typically range from 60 days to 18 months. As a result of the length of the
sales cycle and the typical size of customers' orders, the Company's ability to
forecast the timing and amount of specific sales is limited. A lost or delayed
sale could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business -- Sales and
Marketing."
 
     ACQUISITIONS. Between August 1996 and November 1997, the Company acquired
three businesses. In August 1996, the Company acquired Risk Data, a company that
develops, markets and supports proprietary
 
                                       16
<PAGE>   17
 
software decision products for use in the insurance industry. In November 1996,
the Company acquired Retek, a company that develops, markets and supports
management decision software products for retailers and their vendors. In
November 1997, the Company acquired CompReview, a company that develops, markets
and supports a software product and related services designed to assist in the
management and containment of the medical costs of workers' compensation and
automobile accident medical claims. The Company believes that its future growth
depends, in part, upon the success of these and possible future acquisitions.
There can be no assurance that the Company will successfully identify, acquire
on favorable terms or integrate such businesses, products, services or
technologies. The Company may in the future face increased competition for
acquisition opportunities, which may inhibit the Company's ability to consummate
suitable acquisitions and increase the costs of completing such acquisitions.
The acquisitions of Risk Data, Retek and CompReview, as well as other potential
future acquisitions, will require the Company to successfully manage and
integrate such acquired businesses, which may be located in diverse geographic
locations. Acquiring other businesses also requires the Company to successfully
develop and market products to new industries and markets with which the Company
may not be familiar. It also requires the Company to coordinate (and possibly
change) the diverse operating structures, policies and practices of the acquired
companies and to integrate the employees of the acquired companies into the
Company's organization and culture. Failure of the Company to successfully
integrate and manage acquired businesses, to retain their employees, and to
successfully address new industries and markets associated with such acquired
businesses, would have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, although the
acquisitions of Risk Data, Retek and CompReview have been accounted for as
poolings of interests, future acquisitions may be accounted for as purchases,
resulting in potential charges that may adversely affect the Company's earnings.
Additional acquisitions may also involve the issuance of shares of the Company's
stock to owners of acquired businesses, resulting in dilution in the percentage
of the Company's stock owned by other stockholders. See "Business -- HNC's
Strategy."
 
     RISKS ASSOCIATED WITH MANAGING GROWTH. In recent years, the Company has
experienced changes in its operations that have placed significant demands on
the Company's administrative, operational and financial resources. The growth in
the Company's customer base and expansion of its product functionality, together
with its acquisition of other businesses and their employees, have challenged
and are expected to continue to challenge the Company's management and
operations, including its sales, marketing, customer support, research and
development and finance and administrative operations. The Company's future
performance will depend in part on its ability to successfully manage change,
both in its domestic and international operations, and to adapt its operational
and financial control systems, if necessary, to respond to changes in its
business and to facilitate the integration of acquired businesses with the
Company's operations. The failure of the Company's management to effectively
respond to and manage growth could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     DEPENDENCE ON EMERGING TECHNOLOGIES AND MARKETS. The market for predictive
software solutions is still emerging. The rate at which businesses have adopted
the Company's products has varied significantly by market and by product within
each market, and the Company expects to continue to experience such variations
with respect to its target markets and products in the future. The Company has
introduced products for the healthcare/insurance, financial services and retail
markets. The Company has recently announced several new products, including
PMAdvisor, VeriComp, SelectCast, SelectResponse and SelectResource. To date,
none of these products has achieved any significant degree of market acceptance,
and there can be no assurance that such products will ever be widely accepted.
Although businesses in the Company's target markets have recognized the
advantages of using predictive software solutions to automate the decision-
making process, many have developed decision automation systems internally
rather than licensing them from outside vendors. There can be no assurance that
the markets for the Company's products will continue to develop or that the
Company's products will be widely accepted, if at all. If the markets for the
Company's new or existing products fail to develop, or develop more slowly than
anticipated, the Company's sales would be negatively impacted, which would have
a material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Emerging Market Opportunities."
 
                                       17
<PAGE>   18
 
     RISKS ASSOCIATED WITH TECHNOLOGICAL CHANGE AND DELAYS IN DEVELOPING NEW
PRODUCTS. The market for the Company's predictive software solutions for service
industries is characterized by rapidly changing technology and improvements in
computer hardware, network operating systems, programming tools, programming
languages, operating systems and database technology. The Company's success will
depend upon its ability to continue to develop and maintain competitive
technologies, enhance its current products and develop, in a timely and
cost-effective manner, new products that meet changing market conditions,
including evolving customer needs, new competitive product offerings, emerging
industry standards and changing technology. For example, the rapid growth of the
Internet environment creates new opportunities, risks and uncertainties for
businesses, such as the Company, which develop software solutions that now may
have to be designed to operate in Internet, intranet and other on-line
environments. The Company may not be able to develop and market, on a timely
basis, or at all, product enhancements or new products that respond to changing
technologies. The Company has previously experienced significant delays in the
development and introduction of new products and product enhancements, primarily
due to difficulties with model development, which has in the past required
multiple iterations, as well as difficulties with acquiring data and adapting to
particular operating environments. The length of these delays has varied
depending upon the size and scope of the project and the nature of the problems
encountered. Any significant delay in the completion of new products, or the
failure of such products, if and when installed, to achieve any significant
degree of market acceptance, would have a material adverse effect on the
Company's business, financial condition and results of operations. Any failure
by the Company to anticipate or to respond adequately to changing technologies,
or any significant delays in product development or introduction, could cause
customers to delay or decide against purchases of the Company's products and
would have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Technology" and
"-- Research and Development."
 
     PRODUCT CONCENTRATION. The Company currently has one product or product
line in each of its three target markets that accounts for a majority of the
Company's total revenues from that market. These products in the aggregate
accounted for 60.0%, 59.1% and 57.9% of the Company's total revenues in 1995,
1996 and 1997, respectively. In the healthcare/insurance market, the Company's
revenues from its CRLink product accounted for 29.8%, 24.6% and 23.0% of the
Company's total revenues in 1995, 1996 and 1997, respectively, and are expected
to account for a substantial portion of the Company's total revenues for the
foreseeable future. Continued market acceptance of CRLink will be affected by
future product enhancements and competition. Decline in demand for, or use of,
CRLink, whether as a result of competition, simplification of state workers'
compensation fee schedules, changes in the overall payment system or regulatory
structure for workers' compensation claims, technological change, an inability
to obtain or use state fee schedule or claims data, saturation of market demand,
industry consolidation or otherwise, could result in decreased revenues from
CRLink, which could have a material adverse effect on the Company's business,
financial condition and results of operations. Further, revenues from the Retek
Merchandising System ("RMS"), a retail management product, accounted for 2.2%,
13.6% and 18.9% of the Company's total revenues in 1995, 1996 and 1997,
respectively, and are expected to continue to account for a substantial portion
of the Company's revenues in the foreseeable future. Continued market acceptance
of RMS will be affected by the quality and timely introduction of future product
enhancements and competition. Decline in demand for, or use of, RMS as a result
of continued entry into the retail inventory management market by vendors that
may have significantly greater resources and a broader customer base than the
Company could result in decreased revenues from RMS, which could have a material
adverse effect on the Company's business, financial condition and results of
operations. In addition, decline in demand for RMS, as a result of technological
change, saturation of market demand, industry consolidation or otherwise would
have a material adverse effect on the Company's business, financial condition
and results of operations. Revenues from the Company's Falcon product line for
credit card fraud detection for financial institutions accounted for 28.0%,
20.9% and 16.0% of the Company's total revenues in 1995, 1996 and 1997,
respectively, and are expected to continue to account for a substantial portion
of the Company's total revenues in the foreseeable future. Continued market
acceptance of the Falcon product line will be affected by the quality and timely
introduction of future product enhancements and competition. In addition, it is
possible that patterns of credit card fraud may change in a manner that the
Falcon product line would not detect and that other methods of credit card fraud
prevention may reduce
 
                                       18
<PAGE>   19
 
customers' needs for the Falcon product line. As a result of increasing
saturation of market demand for the Falcon product line, the Company may also
need to rely increasingly on international sales to maintain or increase Falcon
revenue levels. Furthermore, Falcon customers are banks and related financial
institutions. Accordingly, the Company's future success depends upon the capital
expenditure budgets of such customers and the continued demand by such customers
for Falcon products. The financial services industry tends to be cyclical in
nature, which may result in variations in demand for the Company's products. In
addition, there has been and continues to be consolidation in the financial
services industry, which in some cases has lengthened the sales cycle and may
lead to reduced demand for the Company's products. Decline in demand for, or use
of, Falcon, whether as a result of competition, technological change, change in
fraud patterns, the cyclical nature of the financial services industry,
saturation of market demand, fluctuations in interest rates, industry
consolidation, reduction in capital spending or otherwise, could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Markets and Products."
 
   
     DEPENDENCE ON DATA. The development, installation and support of the
Company's credit card fraud control and profitability management, loan
underwriting, home valuation and certain healthcare/insurance products require
periodic model updates. The Company must develop or obtain a reliable source of
sufficient amounts of current and statistically relevant data to analyze
transactions and update its models. For example, in the electronic payments
market, the data required by the Company are collected privately and maintained
in proprietary databases. As a result, the Company and its Falcon and ProfitMax
customers enter into agreements pursuant to which customers agree to provide the
data that the Company requires to analyze transactions, report results and build
new fraud detection and profitability models. For its AREAS home valuation
product, the Company obtains data from commercial databases on available terms
and conditions. Many of the Company's healthcare/insurance products use
historical workers' compensation claims data obtained from customers. CRLink
also uses data from state workers' compensation fee schedules adopted by state
regulatory agencies, and certain third parties have asserted copyright interests
in such data. In most cases, such data must be periodically updated and
refreshed to enable the Company's predictive software products to continue to
work effectively. In addition, the development of new and enhanced products also
depends to a significant extent on the availability of sufficient amounts of
statistically relevant data to enable the Company to develop models. For
example, to expand the geographic coverage of its AREAS product, the Company
would be required to develop or obtain data on home sales in each county for
which AREAS is marketed. There can be no assurance that the Company will be able
to continue to obtain adequate amounts of statistically relevant data on a
timely basis, in the required formats or on reasonable terms and conditions,
whether from customers or commercial suppliers. Any such failure by the Company
to obtain required data when it is needed, for a reasonable price and on
reasonable terms, could have a significant negative impact on existing product
performance, new product development and product pricing which could in turn
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Business -- Customer Service and Support."
    
 
   
     COMPETITION. The market for predictive software solutions for service
industries is intensely competitive and subject to rapid change. Competitors,
many of which have substantially greater financial resources than the Company,
vary in size and in the scope of the products and services they offer. The
Company encounters competition from a number of sources, including (i) other
application software companies, (ii) management information systems departments
of customers and potential customers, including banks, insurance companies and
retailers, (iii) third-party professional services organizations, including
without limitation, consulting divisions of public accounting firms, (iv)
hardware suppliers that bundle or develop complementary software, (v) network
and service providers that seek to enhance their value-added services, (vi)
neural-network tool suppliers and (vii) managed care organizations. In the
healthcare/insurance market, the Company has experienced competition primarily
from NCCI, Corporate Systems and CSC Incorporated. In the workers' compensation
and medical cost administration market, the Company has experienced competition
from MediCode, Medata, Inc. and Embassy Software with regard to software
licensing, and Intracorp and Corvel Corporation in the service bureau operations
market. Additionally, the Company has faced competition from ADP in the
automobile accident medical claims market. In the financial services market, the
Company has experienced competition from Fair, Isaac & Co., Inc., Cogensys (a
subsidiary of Policy Management Systems Corporation), Fannie Mae, Freddie Mac,
IBM, Nestor, Inc., NeuralTech Inc., Neuralware Inc., PMI
    
 
                                       19
<PAGE>   20
 
Mortgage Services Co., VISA International and others. In the retail market, the
Company has experienced competition from JDA Software Group, Inc., SAP AG,
PeopleSoft, Inc., IBM, Manugistics Group, Inc. and others. The Company expects
to experience additional competition from other established and emerging
companies, as well as other technologies. For example, the Company's Falcon
product competes against other methods of preventing credit card fraud, such as
card activation programs, credit cards that contain the cardholder's photograph,
smart cards and other card authorization techniques. Increased competition,
whether from other products or new technologies, could result in price
reductions, fewer customer orders, reduced gross margins and loss of market
share, any of which could materially adversely affect the Company's business,
financial condition and results of operations.
 
     The Company believes that most of its products are currently priced at a
premium when compared to its competitors' products. The market for the Company's
products is highly competitive, and the Company expects that it will face
increasing pricing pressures from its current competitors and new market
entrants. In particular, increased competition could reduce or eliminate such
premiums and cause further price reductions. In addition, such competition could
adversely affect the Company's ability to obtain new long-term contracts and
renewals of existing long-term contracts on terms favorable to the Company. Any
reduction in the price of the Company's products could materially adversely
affect the Company's business, financial condition and results of operations.
 
     Some of the Company's current, and many of the Company's potential,
competitors have significantly greater financial, technical, marketing and other
resources than the Company. As a result, they may be able to respond more
quickly to new or emerging technologies and changes in customer requirements or
to devote greater resources to the development, promotion and sale of their
products than the Company. In addition, current and potential competitors have
established or may establish cooperative relationships among themselves or with
third parties to increase the ability of their products to address the needs of
the Company's prospective customers. Accordingly, it is possible that new
competitors or alliances among competitors may emerge and rapidly gain
significant market share. Also, the Company relies upon its customers to provide
data, expertise and other support for the ongoing updating of the Company's
models. The Company's customers, most of which have significantly greater
financial and marketing resources than the Company, may compete with the Company
in the future or otherwise discontinue their relationships with or support of
the Company. There can be no assurance that the Company will be able to compete
successfully against current and future competitors or that competitive
pressures faced by the Company will not materially adversely affect its
business, financial condition and results of operations. See
"Business -- Competition."
 
   
     RISKS ASSOCIATED WITH RECRUITING AND RETAINING QUALIFIED PERSONNEL. The
Company's success depends to a significant degree upon the continued service of
members of the Company's senior management and other key research, development,
sales and marketing personnel. Accordingly, the loss of any of the Company's
senior management or key research, development, sales or marketing personnel
could have a material adverse effect on the Company's business, financial
condition and results of operations. Only a small number of employees have
employment agreements with the Company, and there can be no assurance that such
agreements will result in the retention of these employees for any significant
period of time. In addition, the untimely loss of a member of the management
team or a key employee of a business acquired by the Company could have a
material adverse effect on the Company's business, financial condition and
results of operations, particularly if such loss occurred before the Company has
had adequate time to familiarize itself with the operating details of that
business. In the past, the Company has experienced difficulty in recruiting a
sufficient number of qualified sales and technical employees. In addition,
competitors may attempt to recruit the Company's key employees. There can be no
assurance that the Company will be successful in attracting, assimilating and
retaining such personnel. The failure to attract, assimilate and retain key
personnel could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Employees" and
"Management."
    
 
   
     CUSTOMER CONCENTRATION. Product licenses to First Data, the largest
provider of credit card charge receipt processing services to banks, accounted
for 8.7%, 8.6% and 7.6% of the Company's total revenues in 1995, 1996 and 1997,
respectively. The Company has licensed First Data to provide its customers with
access to the Company's ProfitMax product pursuant to the ProfitMax Contract
entered into in January 1996. The
    
 
                                       20
<PAGE>   21
 
   
Company's revenues under the ProfitMax Contract represented approximately
one-quarter of the Company's revenues from First Data in 1997. In late January
1998, First Data asserted that certain restrictive covenants under the ProfitMax
Contract violated certain intellectual property laws. First Data also asserted
that the existence of such restrictions made the ProfitMax Contract at least
temporarily unenforceable and that First Data is therefore not obligated to pay
the Company license fees due under the ProfitMax Contract. The Company disputed
First Data's claim, released and waived the above-mentioned restrictive
covenants in the ProfitMax Contract and gave First Data written notice that the
Company intended to terminate the ProfitMax Contract pursuant to its terms
unless First Data cured its failure to pay the delinquent license fees in a
timely manner. Currently, First Data and the Company are working to resolve
their dispute regarding the ProfitMax Contract by negotiating a new agreement;
however, there can be no assurance that such an agreement will be reached or
that the terms of such an agreement would be as favorable to HNC as its existing
contractual arrangements with First Data. If no such agreement can be reached
and First Data maintains its current position, it is possible that litigation or
arbitration could ensue, which would likely result in a loss of anticipated
revenue to the Company under the ProfitMax Contract and possibly other
agreements between the Company and First Data, which could have a material
adverse effect on the Company's business, financial condition and results of
operation. See "Business -- Sales and Marketing."
    
 
     RISKS ASSOCIATED WITH INTERNATIONAL SALES. In 1995, 1996 and 1997,
international operations and export sales (including sales in Canada)
represented 12.6%, 17.7% and 16.8% of the Company's total revenues,
respectively. The Company intends to continue to expand its operations outside
the United States and to enter additional international markets, including by
adding sales and support offices in Europe and Japan, which will require
significant management attention and financial resources. For certain more
mature products, such as Falcon, the Company may need to increase international
sales in order to continue to expand the product's customer base. The Company
has committed and continues to commit significant time and development resources
to customizing certain of its products for selected international markets and to
developing international sales and support channels. There can be no assurance
that the Company's efforts to develop products, databases and models for
targeted international markets or to develop additional international sales and
support channels will be successful. The failure of such efforts, which can
entail considerable expense, could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     International sales are subject to additional inherent risks, including
longer payment cycles, unexpected changes in regulatory requirements, import and
export restrictions and tariffs, difficulties in staffing and managing foreign
operations, the burdens of complying with a variety of foreign laws, greater
difficulty or delay in accounts receivable collection, potentially adverse tax
consequences and political and economic instability. The Company's international
sales are currently denominated predominantly in United States dollars and a
small portion are denominated in British pounds sterling. An increase in the
value of the United States dollar relative to foreign currencies could make the
Company's products more expensive, and therefore potentially less competitive,
in foreign markets. In the future, to the extent the Company's international
sales are denominated in local currencies, foreign currency translations may
contribute to significant fluctuations in the Company's business, financial
condition and results of operations. If for any reason exchange or price
controls or other restrictions on foreign currencies are imposed, the Company's
business, financial condition and results of operations could be materially
adversely affected. See "Business -- Sales and Marketing."
 
     RISKS ASSOCIATED WITH CHANGING REGULATORY ENVIRONMENT. The Company's
customers are subject to a number of government regulations and certain other
industry standards with which the Company's products must comply. For example,
the Company's financial services products are affected by Regulation B
promulgated under the Equal Credit Opportunity Act, by regulations governing the
extension of credit to consumers and by Regulation E promulgated under the
Electronic Fund Transfers Act governing the transfer of funds from and to
consumer deposit accounts, as well as VISA and MasterCard electronic payment
standards. In the mortgage services market, the Company's products are affected
by regulations such as Fannie Mae and Freddie Mac regulations for conforming
loans, Uniform Standards of Professional Appraisal Practice and appraisal
standards for federally insured institutions under the Financial Institutions
Reform, Recovery and Enforcement Act. In addition, recent regulatory initiatives
have restricted the availability of bank and credit bureau data, reflecting a
consumer privacy trend that could limit the Company's ability to
 
                                       21
<PAGE>   22
 
obtain or use certain credit-related information. It is also possible that
insurance-related regulations may in the future apply to the Company's
healthcare/insurance products. In many states, including California, there have
been periodic legislative efforts to reform workers' compensation laws in order
to reduce the cost of workers' compensation insurance and to curb abuses of the
workers' compensation system, and such changes, if adopted, might adversely
affect the Company's healthcare/insurance business. In addition, if state-
mandated workers' compensation laws or regulations or state workers'
compensation fee schedules are simplified, such changes would diminish the need
for, and the benefit provided by, the CRLink product. Changes in workers'
compensation laws or regulations could also adversely affect the Company's
healthcare/ insurance products by making them obsolete, or by requiring
extensive changes in these products to reflect new workers' compensation rules.
To the extent that the Company sells new products targeted to markets that
include regulated industries and businesses, the Company's products will need to
comply with these additional regulations. Any failure of the Company's products
to comply with existing or new regulations and standards could result in legal
action against the Company or its customers by regulatory authorities or by
third parties, including actions seeking civil or criminal penalties,
injunctions against the Company's use of data or civil damages, any of which
could have a material adverse effect on the Company's business, financial
condition and results of operations. The Company may also be liable to its
customers for failure of its products to comply with such regulatory
requirements. Furthermore, changes to these regulations and standards or the
adoption of new regulations or standards that affect the Company's products
could affect the performance of such products and have a material adverse effect
on the Company's business, financial condition and results of operations.
 
   
     PROTECTION OF INTELLECTUAL PROPERTY. The Company relies on a combination of
patent, copyright, trademark and trade secret laws and confidentiality
procedures to protect its proprietary rights. The Company currently owns seven
issued United States patents and has four United States patent applications
pending. The Company has applied for additional patents for its Falcon
technology in Canada, Europe and Japan and for its MIRA product in Australia,
Canada and Europe. There can be no assurance that patents will be issued with
respect to pending or future patent applications or that the Company's patents
will be upheld as valid or will prevent the development of competitive products.
The Company seeks to protect its software, documentation and other written
materials under trade secret and copyright laws, which afford only limited
protection. As part of its confidentiality procedures, the Company generally
enters into invention assignment and proprietary information agreements with its
employees and independent contractors and nondisclosure agreements with its
distributors, corporate partners and licensees, and limits access to and
distribution of its software, documentation and other proprietary information.
Despite these precautions, it may be possible for a third party to copy or
otherwise to obtain and use the Company's products or technology without
authorization, or to develop similar technology independently. In addition, to
ensure that customers will not be adversely affected by an interruption in the
Company's business, the Company places source code for certain of its products
into escrow, which may increase the likelihood of misappropriation or other
misuse of the Company's intellectual property. Moreover, effective protection of
intellectual property rights may be unavailable or limited in certain foreign
countries in which the Company has done and may do business. Also, the Company
has developed technologies under research projects conducted under agreements
with various United States Government agencies or subcontractors to such
agencies. Although the Company has acquired certain commercial rights to such
technologies, the United States Government typically retains ownership of
certain intellectual property rights and licenses in the technologies developed
by the Company under such contracts, and in some cases can terminate the
Company's rights in such technologies if the Company fails to commercialize them
on a timely basis. In addition, under certain United States Government
contracts, the results of the Company's research may be made public by the
government, which could limit the Company's competitive advantage with respect
to future products based on such research. See "Business -- Intellectual
Property and Other Proprietary Rights."
    
 
   
     INFRINGEMENT OF PROPRIETARY RIGHTS. In the past, the Company has received
communications from third parties asserting that Company trademarks infringed
such other parties' trademarks, none of which has resulted in litigation or
losses to the Company. Given the Company's ongoing efforts to develop and market
new technologies and products, the Company may receive communications from third
parties asserting that the Company's products infringe, or may infringe, their
intellectual property rights. If as a result of any such
    
 
                                       22
<PAGE>   23
 
claims the Company were precluded from using certain technologies or
intellectual property rights, licenses to such disputed third-party technology
or intellectual property rights might not be available on reasonable commercial
terms, if at all. Furthermore, the Company may initiate claims or litigation
against third parties for infringement of the Company's proprietary rights or to
establish the validity of the Company's proprietary rights. Litigation, either
as plaintiff or defendant, could result in significant expense to the Company
and divert the efforts of the Company's technical and management personnel from
productive tasks, whether or not such litigation is resolved in favor of the
Company. In the event of an adverse ruling in any such litigation, the Company
might be required to pay substantial damages, discontinue the use and sale of
infringing products, expend significant resources to develop non-infringing
technology or obtain licenses to infringing technology, and the court might
invalidate the Company's patents, trademarks or other proprietary rights. In the
event of a successful claim against the Company and the failure of the Company
to develop or license a substitute technology, the Company's business, financial
condition and results of operations would be materially and adversely affected.
As the number of software products increases and the functionality of these
products further overlaps, the Company believes that software developers may
become increasingly subject to infringement claims. Any such claims, with or
without merit, can be time consuming and expensive to defend and could
materially and adversely affect the Company's business, financial condition and
results of operations. See "Business -- Intellectual Property and Other
Proprietary Rights."
 
     RISK OF PRODUCT DEFECTS AND PRODUCT LIABILITY. Software products as complex
as those offered by the Company often contain undetected errors or failures when
first introduced or as new versions are released. In addition, to the extent
that the Company may have to develop new products that operate in new
environments, such as the Internet, the possibility for program errors and
failures may increase due to factors such as the use of new technologies or the
need for more rapid product development that is characteristic of the Internet
market. Despite pre-release testing by the Company and by current and potential
customers, there still may be errors in new products, even after commencement of
commercial shipments. The occurrence of such errors could result in delay in, or
failure to achieve, market acceptance of the Company's products, which could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
     Although the Company's license agreements with its customers typically
contain provisions designed to limit the Company's exposure to potential product
liability claims, it is possible that such limitation of liability provisions
may not be effective as a result of existing or future laws or unfavorable
judicial decisions. Because the Company's products are used in business-critical
applications, any errors or failures in such products may give rise to
substantial product liability claims, which could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
     YEAR 2000 COMPLIANCE. Many currently installed computer systems and
software products are coded to accept only two digit entries in the date code
field. These date code fields will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, in less
than two years, computer systems and/or software used by many companies may need
to be upgraded to comply with such "Year 2000" requirements. Significant
uncertainty exists in the software industry concerning the potential effects
associated with such compliance. The Company anticipates that it will need to
devote resources in the next two years to modify its CRLink product to properly
process dates beyond December 31, 1999. The Company expects that the cost of
making these modifications and distributing the modified product to existing
customers will be approximately $500,000. These modifications and the resources
that the Company expects to devote to such modifications may divert management
and engineering attention from, or delay the development and introduction of,
new products and enhancements to existing products. The inability of the Company
to complete such modifications successfully and on a timely basis, or the
inability of the Company to devote sufficient resources to continuing updates
and enhancements to the CRLink product, could have a material adverse effect on
the Company's business, financial condition and results of operations. In
addition, the Company believes that the purchasing patterns of customers and
potential customers may be affected by Year 2000 issues as companies expend
significant resources to correct or patch their current software systems for
Year 2000 compliance. These expenditures may result in reduced funds available
to purchase software products such as those offered by the Company, which could
result in a material adverse effect on the Company's business, financial
condition and results of operations.

     FACTORS INHIBITING TAKEOVER. The Board of Directors is authorized to issue
up to 4,000,000 shares of Preferred Stock and to determine the price, rights,
preferences, privileges and restrictions, including voting rights, of those
shares without any further vote or action by the stockholders. The rights of the
holders of Common Stock will be subject to, and may be adversely affected by,
the rights of the holders of any Preferred Stock that may be issued in the
future. The issuance of Preferred Stock, while providing desirable flexibility
in connection with possible acquisitions and other corporate purposes, could
have the effect of making it more difficult for a third party to acquire a
majority of the outstanding voting stock of the Company. The Company has no
current plans to issue shares of Preferred Stock. In addition, Section 203 of
the Delaware General Corporation Law restricts certain business combinations
with any "interested stockholder" as defined by such statute. The statute may
have the effect of delaying, deferring or preventing a change in control of the
Company.
 
ITEM 2. PROPERTIES
 
     The Company's principal administrative, sales, marketing, support, research
and development facilities are located in approximately 85,000 square feet of
space in San Diego, California. The Company and its subsidiaries also lease an
aggregate of approximately 95,000 square feet of additional office space
elsewhere in San Diego and in Atlanta, Georgia; Minneapolis, Minnesota; Costa
Mesa, California; and Irvine, California. The Company and its subsidiaries also
maintain numerous field offices in the United States and in foreign countries.
The Company believes that its current facilities are adequate to meet its needs
for the foreseeable future. The Company believes that suitable additional or
alternative space will be available in the future on commercially reasonable
terms as needed.
 
ITEM 3. LEGAL PROCEEDINGS
 
     The Company is not a party to any litigation other than ordinary routine
litigation incidental to the business.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
   
     A Special Meeting of Stockholders was held on November 25, 1997 to approve
two proposals: (1) a proposal to approve the issuance by the Company of shares
of HNC Common Stock and options to purchase HNC Common Stock to the stockholders
and optionholders, respectively, of CompReview; and (2) a proposal to approve an
amendment to the Company's 1995 Equity Incentive Plan increasing the number of
shares of the Company's Common Stock reserved for issuance thereunder by 750,000
shares. The proposals passed by the following vote:

OVERVIEW
 
     HNC develops, markets and supports predictive software solutions for
leading service industries. These predictive software solutions employ
proprietary neural-network predictive decision engines, profiles, traditional
statistical modeling, business models, expert rules and context vectors to
convert existing data and business experiences into meaningful recommendations
and actions. HNC was founded in 1986 to provide software tools and contracted
technology services using neural-network technology.
 
     In August 1996, HNC completed its acquisition of Risk Data in a transaction
accounted for as a pooling of interests. Risk Data is based in Irvine,
California and develops, markets and supports proprietary software decision
products for use in the insurance industry. In 1996, HNC formed Aptex Software
Inc. ("Aptex"), a majority-owned subsidiary located in San Diego, California
that develops, markets and supports electronic text analysis technology in
products designed for the Internet and other environments. In November 1996, HNC
completed its acquisition of Retek in a transaction accounted for as a pooling
of interests. Retek is based in Minneapolis, Minnesota and develops, markets and
supports software products that provide merchandise management and other
management tools to retailers and their vendors. In November 1997, the Company
completed its acquisition of CompReview, in a transaction accounted for as a
pooling of interests. CompReview is located in Costa Mesa, California and
develops, markets and supports a software product and related services designed
to assist in the management and containment of the medical costs of workers'
compensation and automobile accident medical claims. CompReview provides its
product and services primarily to insurance companies, managed care
organizations, third party administrators and large self-insured employers. The
Company anticipates that from time to time it will consider acquisitions of
other businesses in order to expand the markets served by the Company and to
acquire complementary technologies, products and personnel. See
"Business -- Risk Factors -- Acquisitions" and "Business -- HNC's Strategy."
 
     After giving retroactive effect to the Company's acquisitions of Risk Data,
Retek and CompReview, HNC experienced compound annual growth in total revenues
of 63% from 1993 through 1997. See "Business -- Risk Factors -- Risks Associated
with Managing Growth." This revenue growth resulted primarily from increased
license fees for the Retek Merchandising System, CRLink, Falcon, MIRA and
ProfitMax products and, to a lesser extent, from increased license fees for the
Active Retail Intelligence, Retek Data Warehouse, PMAdvisor, CompCompare,
Capstone and AREAS products. Because of the long sales and development cycle
associated with the Company's products, the Company has not received significant
revenues to date from the SelectCast, SelectResponse, SelectResource, VeriComp
or PMAdvisor products. See "Business -- Risk Factors -- Lengthy and
Unpredictable Sales Cycle."
 
   
     The Company markets most of its predictive software solutions as an ongoing
service that includes software licenses, decision model updates, application
consulting and on-line or on-site support and maintenance. The Company's pricing
for the CRLink, Falcon, MIRA, ProfitMax, AREAS, PMAdvisor, CompCompare and
ProviderCompare products typically includes an annual or monthly usage fee and a
one to seven year contract commitment. In 1995, 1996 and 1997, annual license
and maintenance revenues from these contracts represented 61.2%, 56.1% and 55.2%
of the Company's total revenues, respectively.
    
 
     The Company's revenues and operating results have varied significantly in
the past and may do so in the future. Because the Company's expense levels are
based in part on its expectations regarding future revenues and in the short
term are fixed to a large extent, the Company may be unable to adjust its
spending in time to
 
                                       28
<PAGE>   29
 
   
compensate for any unexpected revenue shortfall. Factors affecting operating
results include market acceptance of the Company's products; the relatively
large size and small number of customer orders that may be received during a
given period; customer cancellation of long-term contracts yielding recurring
revenues or customers' ceasing their use of Company products for which the
Company's fees are usage based; the length of the Company's sales cycle; the
Company's ability to develop, introduce and market new products and product
enhancements; the timing of new product announcements and introductions by the
Company and its competitors; changes in the mix of distribution channels;
changes in the level of operating expenses; the Company's ability to achieve
progress on percentage-of-completion contracts; the Company's success in
completing certain pilot installations for contracted fees; competitive
conditions in the industry; domestic and international economic conditions; and
market conditions in the Company's targeted markets. In addition, as a result of
recently issued guidance on software revenue recognition, license agreements
entered into during a quarter may not meet the Company's revenue recognition
criteria. Therefore, even if the Company meets or exceeds its forecast of
aggregate licensing and other contracting activity, it is possible that the
Company's revenues would not meet expectations. Furthermore, the Company's
operating results may be affected by factors unique to certain of its product
lines. For example, the Company derives a substantial and increasing portion of
its revenues from its retail products, which are generally priced as "perpetual"
license transactions in which the Company receives a one-time license fee. The
Company recognizes these fees as revenue upon delivery of the software and
acceptance by the customer. Thus, failure to complete a perpetual license
transaction during a fiscal quarter could have a disproportionate adverse impact
on the Company's operating results for that quarter.
    
 
   
     The Company expects fluctuations in its operating results to continue for
the foreseeable future. Accordingly, the Company believes that period-to-period
comparisons of its financial results should not be relied upon as an indication
of future performance. The Company may not be able to maintain profitability on
a quarterly or annual basis in the future. Due to all of the foregoing factors,
it is possible that in some future quarter the Company's operating results will
be below the expectations of public market analysts and investors. In that
event, the price of the Company's Common Stock would likely be materially
adversely affected.
    
 
RESULTS OF OPERATIONS
 
     The Company's statements of income for all periods presented give
retroactive effect to the acquisitions of Risk Data, Retek and CompReview in
August 1996, November 1996 and November 1997, respectively, each of which was
accounted for as a pooling of interests.
 
  Total Revenues
 
   
     The Company's revenues are comprised of license and maintenance revenues,
installation and implementation revenues, contracts and other revenues and
service bureau revenues. Total revenues increased by 63.5% to $71.4 million in
1996 and by 59.2% to $113.7 million in 1997. International operations and export
sales represented 12.6%, 17.7% and 16.8% of total revenues in 1995, 1996 and
1997, respectively. The retail product line currently has more sales in
international markets than the healthcare/insurance and financial services
product lines combined. The Company believes that international sales represent
a significant opportunity for revenue growth and expects international sales to
increase as a percent of total revenue.
    
 
          License and Maintenance Revenues. The Company's license and
     maintenance revenues are derived from annual license fees, monthly license
     fees, perpetual license fees and annual maintenance fees. The Company
     typically licenses many of its products for an annual or monthly usage fee
     under long-term contracts that include software licenses, decision model
     updates, application consulting, and on-line or on-site support and
     maintenance. The Company's revenue from periodic software license and
     maintenance agreements is generally recognized ratably over the respective
     license or agreement periods. Revenue from certain short-term periodic
     software license and maintenance agreements with guaranteed minimum license
     fees is recognized as related services are performed. Transactional fees
     are recognized as revenue based on system usage or when fees based on
     system usage exceed the monthly minimum license fees. Revenue from
     perpetual licenses of the Company's software for which there are no
     significant continuing obligations and collection of the related
     receivables is probable is recognized on
 
                                       29
<PAGE>   30
 
   
     delivery of the software and acceptance by the customer. Recently issued
     guidance on software revenue recognition could lead to unanticipated
     changes in the Company's revenue recognition practices. See "Risk
     Factors -- Potential Fluctuations in Operating Results" and "New Accounting
     Pronouncements."
    
 
   
          License and maintenance revenues increased by 99.1% to $48.9 million
     in 1996 and by 83.4% to $89.6 million in 1997. The increase from 1995 to
     1996 was due primarily to the growth of license fees in all markets,
     particularly from the Retek Merchandising System, CRLink and Falcon, and,
     to a lesser extent, MIRA and CompCompare. The increase from 1996 to 1997
     was due primarily to the growth of license fee revenues from the Retek
     Merchandising System and CRLink. Also contributing to the increase were
     increased license fees from other retail products, such as ARI and Retek
     Data Warehouse, financial services products such as Falcon, ProfitMax and
     Capstone, and other healthcare/insurance products, such as PMAdvisor and
     MIRA.
    
 
          Installation and Implementation Revenues. Revenues from software
     installations and implementations are generally recognized as the services
     are performed using the percentage of completion method based on costs
     incurred to date compared to total estimated costs at completion. Amounts
     received in advance of performance under the contracts are recorded as
     deferred revenue and are generally recognized within one year from receipt.
 
          Installation and implementation revenues increased by 44.0% to $6.7
     million in 1996 and by 59.9% to $10.7 million in 1997. Substantially all of
     the increase from 1995 to 1996 was due primarily to growth in the
     installations of Retek Data Forecasting as this product moved from
     development into production. The increase from 1996 to 1997 was due
     primarily to growth in the installations of Capstone and ProfitMax.
 
          Contracts and Other Revenues. Contracts and other revenues are derived
     primarily from new product development contracts with commercial customers
     and research contracts with the United States Government. The Company
     typically contracts with one or two commercial partners for pilot
     development and installation of its new products and with the United States
     Government for additional research funds. Revenues from contract services
     are generally recognized as the services are performed using the percentage
     of completion method based on costs incurred to date compared to total
     estimated costs at completion. Revenue from hardware product sales, which
     is included in contracts and other revenue, is recognized upon shipment to
     the customer.
 
          Contracts and other revenues increased by 21.7% to $11.1 million in
     1996 and decreased by 30.2% to $7.8 million in 1997. The increase in 1996
     was primarily the result of greater revenues from commercial new product
     pilot installation contracts with customers in support of the Company's
     development of ProfitMax, SelectCast, Falcon Sentry and Capstone. The
     decrease in 1997 was primarily the result of products such as ProfitMax,
     Retek Data Forecasting and Capstone moving from development into
     production.
 
          During 1997, the Company had fewer new product development projects
     and new product pilot installations than during 1996. There can be no
     assurance that any of these product development projects or pilot
     installations will be successful or be completed within anticipated time
     schedules or that the customers who serve as pilot installation sites will
     be satisfied with these products or agree to license them. If the Company's
     new product development efforts are unsuccessful, are not completed on a
     timely basis or are not well received by pilot customers, the Company may
     be compelled to delay or discontinue the release of production versions of
     these products or bear increased expense to bring these pilot products to
     market, either of which would have a material adverse effect on the
     Company's business, financial condition and results of operations.
 
          Service Bureau Revenues. Service bureau revenues are derived from the
     Company's service bureau operations, which provide CRLink's functionality
     to customers that do not wish to obtain a license, that use this service
     until they can implement their own internal CRLink operation or that use
     this service when their volumes peak to high levels. Service bureau
     customers typically subscribe for services under month-to-month agreements.
     Service bureau fees are recognized as revenue when the processing services
     are performed.
 
                                       30
<PAGE>   31
 
          Service bureau revenues decreased by 11.6% to $4.7 million in 1996 and
     increased by 18.8% to $5.6 million in 1997. The decrease in 1996 was
     primarily a result of the significant increase in license revenues as the
     Company's sales efforts were focused on licensing CRLink to customers
     rather than marketing service bureau services. The increase in 1997 was
     primarily due to an increase in the number of customers utilizing service
     bureau operations.

</TABLE>
 
   
          License and Maintenance Gross Margin. License and maintenance costs
     primarily represent the Company's expenses for personnel engaged in
     customer support, travel to customer sites and documentation materials. The
     Company's gross margin on license and maintenance revenues was 67.8%, 71.9%
     and 77.8% in 1995, 1996 and 1997, respectively. In 1996, the improvement in
     gross margin was the result of the Company's ability to move from price
     discounts for early adopters of its products to full pricing for products
     sold to subsequent customers as well as a higher volume of international
     licenses, which generate relatively higher margins than domestic operations
     due, in part, to lower overhead expenses as a result of less corporate
     infrastructure. Gross margin improved in 1997 due primarily to license fees
     increasing at a higher rate than the costs associated with providing these
     licenses. This increase was primarily attributable to increased pricing
     producing higher margins in the retail and healthcare/insurance markets.
    
 
   
          Installation and Implementation Gross Margin. Installation and
     implementation costs consist primarily of personnel-related costs, travel
     and equipment. The Company's gross margin on installation and
     implementation revenues was 69.3%, 59.4% and 51.7% in 1995, 1996 and 1997,
     respectively. In 1996, the decrease in the gross margin was due primarily
     to new installations of Retek Data Forecasting, which have substantially
     lower margins than installations of Falcon products, which represented a
     majority of installations in 1995. Gross margin decreased in 1997 due
     primarily to an increase in Capstone implementations, which have
     substantially lower margins than implementations of Falcon products.
    
 
          Contracts and Other Gross Margin. Contracts and other costs consist
     primarily of personnel-related costs. The Company's gross margin on
     contracts and other revenues was 24.6%, 30.9% and 30.0% in 1995, 1996 and
     1997, respectively. The improvement in gross margin during 1996 was due
     primarily to the Company's increased ability to better price its new pilot
     projects. The slight decrease in gross margin for 1997 was due to the
     decrease in new product development contracts, while government projects
     with substantially lower margins remained relatively constant in absolute
     dollars.
 
   
          Service Bureau Gross Margin. Service bureau costs consist primarily of
     the personnel and facilities costs of operating the service bureaus. The
     Company's gross margin on service bureau revenues was 43.4%, 28.9% and
     23.1% in 1995, 1996 and 1997, respectively. The decrease in 1996 was a
     result of the loss of a customer in early 1996 for which the Company was
     able to recognize higher than usual margins during 1995. The decrease in
     1997 was attributable to an increase in fixed costs and in labor costs
     required to support the service bureau business that outpaced the increase
     in revenue. This was the result of a more static customer base and higher
     fixed costs associated with the infrastructure necessary to run the service
     bureau operation.

       Other Operating Expenses
 
          Research and Development Expenses. Research and development expenses
     consist primarily of salaries and other personnel-related expenses,
     subcontracted development services, depreciation for development equipment
     and supplies. Research and development expenses increased from $7.0 million
     in 1995 to $13.8 million in 1996 and to $21.2 million in 1997, representing
     16.0%, 19.3% and 18.6% of total revenues in 1995, 1996 and 1997,
     respectively. Research and development expenses increased in absolute
     dollars due to the development costs associated with new releases of
     several products in the retail and financial services product lines. The
     increased research and development expenses in absolute dollars and as a
     percentage of revenues in 1996 was primarily the result of greater staffing
     to support more new product development programs, primarily for ProfitMax,
     Capstone, CompCompare, ProviderCompare and the Retek Merchandising System.
     The 1996 costs also included the initial product development costs of the
     Company's Aptex business unit, which did not have a significant impact on
     revenues. Statement of Financial Accounting Standards No. 86, "Accounting
     for the Costs of Computer Software to be Sold, Leased or Otherwise
     Marketed," requires capitalization of certain software development costs
     subsequent to the establishment of technological feasibility. Based on the
     Company's product development process, technological feasibility is not
     established until completion of a working model. Costs incurred by the
     Company between completion of the working model and the point at which a
     product is ready for general release have been insignificant. As a result,
     no significant software development costs were capitalized through December
     31, 1997. The Company anticipates that research and development expenses
     will increase in dollar amount and could increase as a percentage of total
     revenues for the foreseeable future.
 
          Sales and Marketing Expenses. Sales and marketing expenses consist
     primarily of salaries and benefits, commissions, travel, entertainment and
     promotional expenses. Sales and marketing expenses increased from $7.3
     million in 1995 to $11.9 million in 1996 and to $22.0 million in 1997,
     representing 16.6%, 16.7% and 19.4% of total revenues in 1995, 1996 and
     1997, respectively. The increases were primarily a result of increased
     staffing as the Company built its direct sales and marketing staff, opened
     sales offices in Japan and in several locations in Europe, and increased
     expenses for trade shows, advertising and other marketing programs. The
     Company expects sales and marketing expenses to continue to increase for
     the foreseeable future. Such expenses could also increase as a percentage
     of total revenues as the Company continues to develop a direct sales force
     in Europe and other international markets, expand its domestic sales and
     marketing organization and increase the breadth of its product lines.
 
   
          General and Administrative Expenses. General and administrative
     expenses consist primarily of personnel costs for finance, contract
     administration, human resources and general management, as well as
     acquisition, insurance and professional services expenses. General and
     administrative expenses increased from $5.1 million in 1995 to $8.6 million
     in 1996 and to $12.6 million in 1997, representing 11.7%, 10.3% and 9.8% of
     total revenues, respectively. General and administrative expenses included
     $1.2 million of acquisition expenses related to the acquisitions of Risk
     Data and Retek in 1996 and $1.4 million of acquisition expenses primarily
     related to the acquisition of CompReview in 1997. Excluding acquisition
     expenses, general and administrative expenses were $5.1 million, $7.4
     million and $11.2 million in 1995, 1996 and 1997, respectively. The primary
     reason for these increases in absolute dollars was increased staffing to
     support the Company's growth and additional expenses associated with being
     a public company.
    
 
  Operating Income
 
     The above factors resulted in operating income of $5.1 million,
constituting 11.6% of total revenues in 1995, $9.7 million, constituting 13.5%
of total revenues in 1996, and $23.0 million, constituting 20.3% of total
revenues in 1997. The Company does not expect that operating income will
continue to increase significantly as a percentage of total revenues.

<PAGE>   33
 
  Other Income (Expense) Net
 
     Interest and other income, net of interest expense, increased from $484,000
in 1995 to $1.7 million in 1996 and to $1.9 million in 1997. The increase in
1996 was primarily attributable to increased interest income in 1996 from higher
cash and investment balances, which consisted primarily of the proceeds from the
Company's initial public offering in June 1995 and secondary public offering in
December 1995. The increase in 1997 was primarily due to a decrease in interest
expense of approximately $397,000 primarily related to the repayment of Risk
Data's bank notes payable during the third quarter of 1996, offset by a decrease
in interest income of approximately $165,000.
 
  Income Tax (Benefit) Provision
 
     The income tax benefit of $511,000 in 1995 was primarily attributable to
the recognition of a $2.2 million deferred tax asset based on anticipated future
utilization of all of the Company's remaining net operating loss carryforwards
and research and development credit carryforwards. The income tax benefit of
$534,000 in 1996 was primarily attributable to the recognition of a $2.7 million
deferred tax asset based on anticipated future utilization of all of the
remaining net operating loss carryforwards and research and development credit
carryforwards relating to Risk Data and Retek. That deferred tax asset had
previously been offset by a valuation allowance. The Company released the
valuation allowance during the fourth quarter of 1996, based upon management's
assessment that it was more likely than not that the Company would realize the
asset in future periods.
 
   
     The 1997 income tax provision of $7.4 million, or 29.5% of pre-tax income,
was lower than 1997 taxes at statutory rates primarily as a result of
CompReview's subchapter S corporation status prior to the acquisition, which
resulted in most of CompReview's tax liability being borne by its former
stockholders. As of the date of the acquisition, CompReview's tax status was
changed to C corporation. In the future, the Company expects that the effective
tax rate will be reflective of the tax rate of other California-based companies.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     The $21.0 million of net cash provided by operating activities in 1997
represented net income before depreciation and amortization of approximately
$22.4 million, further increased by a decrease in deferred income taxes of $6.9
million and offset by an increase in accounts receivable of $11.1 million. Net
cash used in investing activities was $7.7 million in 1997 primarily due to $9.6
million expended for property and equipment during 1997, including $6.0 million
for computer equipment to support the increased staffing across the Company, and
$1.9 million for furniture and fixtures primarily related to the relocation of
the Company's Minneapolis facility, offset by approximately $1.9 million of
proceeds from sales and maturities of investments available for sale net of
purchases of such investments. Net cash used in financing activities was $3.2
million in 1997 primarily due to $6.8 million in distributions to the former
CompReview stockholders offset by $4.0 million in net proceeds from issuances of
common stock.
    
 
   
     As of December 31, 1997, the Company had $42.9 million in cash, cash
equivalents and investments. The Company believes that its current cash, cash
equivalents and investments available for sale balances, borrowings under its
credit facility and net cash provided by operating activities, will be
sufficient to meet its working capital and capital expenditure requirements for
at least the next 12 months. A portion of the Company's cash could be used to
repurchase shares of the Company's Common Stock from time to time in the open
market. Management intends to invest the Company's cash in excess of current
operating requirements in short-term, interest-bearing, investment-grade
securities. A portion of the Company's cash could also be used to acquire or
invest in complementary businesses or products or otherwise to obtain the right
to use complementary technologies or data. From time to time, in the ordinary
course of business, the Company evaluates potential acquisitions of such
businesses, products, technologies or data. The Company has no present
understandings, commitments or agreements with respect to any material
acquisition of businesses, products, technologies or data.

YEAR 2000 COMPLIANCE
 
     The Company anticipates that it will need to devote resources in the next
two years to modify its CRLink product to properly process dates beyond December
31, 1999. The Company expects that the cost of making these modifications and
distributing the modified product to existing customers will be approximately
$500,000. These modifications and the resources that the Company expects to
devote to such modifications may divert management and engineering attention
from, or delay the development and introduction of, new products and
enhancements to existing products. The inability of the Company to complete such
modifications successfully and on a timely basis, or the inability of the
Company to devote sufficient resources to continuing updates and enhancements to
the CRLink product, could have a material adverse effect on the Company's
business, financial condition and results of operations. In addition, the
Company believes that the purchasing patterns of customers and potential
customers may be affected by Year 2000 issues as companies expend significant
resources to correct or patch their current software systems for Year 2000
compliance. These expenditures may result in reduced funds available to purchase
software products such as those offered by the Company, which could result in a
material adverse effect on the Company's business, financial condition and
results of operations.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130 ("FAS 130"), "Reporting
Comprehensive Income," which the Company is required to adopt for 1998. This
statement will require the Company to report in the financial statements, in
addition to net income, comprehensive income and its components including
foreign currency items and unrealized gains and losses on certain investments in
debt and equity securities. Upon adoption of FAS 130, the Company is also
required to reclassify financial statements for earlier periods provided for
comparative purposes. The adoption of FAS 130 will not have a significant impact
on the Company's consolidated financial statement disclosures.
 
     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131 ("FAS 131"), "Disclosures about Segments of an Enterprise and Related
Information," which the Company is required to adopt for its 1998 annual
financial statements. This statement establishes standards for reporting
information about operating segments in annual financial statements and requires
selected information about operating segments in interim financial reports
issued to stockholders. It also establishes standards for related disclosures
about products and services, geographic areas and major customers. Under FAS
131, operating segments are to be determined consistent with the way that
management organizes and evaluates financial information internally for making
operating decisions and assessing performance. The Company has not determined
the impact of the adoption of this new accounting standard on its consolidated
financial statement disclosures.
 
   
     In October 1997, the American Institute of Certified Public Accountants
issued Statement of Position No. 97-2 ("SOP 97-2"), "Software Revenue
Recognition," which the Company is required to adopt for agreements entered into
with customers beginning in 1998. This statement provides guidance for software
revenue recognition matters primarily from a conceptual level and does not
include specific implementation guidance. Based on its reading and
interpretation of SOP 97-2, the Company believes that the adoption of SOP 97-2
will not have a significant impact on its financial statements; however,
detailed implementation guidelines for this standard have not yet been issued.
Once issued, such detailed implementation guidance could lead to unanticipated
changes in the Company's current revenue recognition practices, and such changes
could be material to the Company's financial statements.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
of HNC Software Inc.
 
In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, of cash flows and of changes in stockholders'
equity present fairly, in all material respects, the financial position of HNC
Software Inc. and its subsidiaries at December 31, 1996 and 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1997, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

     Transaction costs of $563, $515 and $1,440 were incurred to complete the
acquisitions of Risk Data, Retek and CompReview, respectively. Transaction costs
were deferred and charged to income when the related transactions were
consummated. Transaction costs consisted primarily of investment banker, legal
and accounting fees, and printing, mailing and registration expenses.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany transactions and
balances have been eliminated.
 
     During 1996, the Company established Aptex Software Inc. ("Aptex"), a
majority owned subsidiary, in order to develop, market and support certain text
analysis technology that is being used to develop products for the Internet
market. The minority stockholders' interest in Aptex's financial position and
results of operations is presented as a minority interest in the Company's
consolidated financial statements.
 
  Financial Statement Preparation
 
     The preparation of financial statements, in conformity with generally
accepted accounting principles, requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.
 
  Cash Equivalents
 
     Cash equivalents are highly liquid investments and consist of investments
in money market accounts and commercial paper purchased with maturities of three
months or less.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
  Investments
 
     Management determines the appropriate classification of its investments in
marketable debt and equity securities at the time of purchase and re-evaluates
such designation as of each balance sheet date. The Company classifies all
securities as "available for sale" and carries them at fair value with
unrealized gains or losses related to these securities included in stockholders'
equity in the Company's consolidated balance sheet.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. The Company computes
depreciation and amortization using either the straight-line method over the
estimated useful lives of the assets of three to seven years or an accelerated
method over the estimated useful lives of the assets of five to seven years. The
Company amortizes leasehold improvements over the shorter of their estimated
useful lives or the remaining term of the related lease. Repair and maintenance
costs are charged to expense as incurred.
 
  Software Costs
 
     Software costs are recorded at cost and amortized over their estimated
useful lives of 36 to 42 months. Software costs are comprised of purchased
software and other rights that are stated at the lower of cost or net realizable
value. At December 31, 1996 and 1997, software costs of $2,561 and $2,581,
respectively, were included in other assets in the consolidated balance sheet
net of accumulated amortization of $642 and $1,451, respectively.
 
     Development costs for software to be licensed or sold that are incurred
from the time technological feasibility is established until the product is
available for general release to customers are capitalized and reported at the
lower of cost or net realizable value. Through December 31, 1997, no significant
amounts were expended subsequent to reaching technological feasibility.
 
  Long-Lived Assets
 
     The Company investigates potential impairments of long-lived assets,
certain identifiable intangibles and associated goodwill when events or changes
in circumstances have made recovery of an asset's carrying value unlikely. An
impairment loss would be recognized if the sum of the expected future net cash
flows were less than the carrying amount of the asset. No such impairments of
long-lived assets existed through December 31, 1997.
 
  Stock-Based Compensation
 
     The Company measures compensation expense for its stock-based employee
compensation plans using the intrinsic value method and provides pro forma
disclosures of net income and earnings per share as if the fair value-based
method had been applied in measuring compensation expense.
 
  Revenue Recognition
 
     The Company's revenue from periodic software license and maintenance
agreements is generally recognized ratably over the respective license periods.
Revenue from certain short-term periodic software license and maintenance
agreements with guaranteed minimum license fees is recognized as related
services are performed. Transactional fees are recognized as revenue based on
system usage or when fees based on system usage exceed the monthly minimum
license fees. Revenue from perpetual licenses of the Company's software for
which there are no significant continuing obligations and collection of the
related receivables is probable is recognized on delivery of the software and
acceptance by the customer. Revenue from hardware product sales, which is
included in contracts and other revenue, is recognized upon shipment to the
customer.

                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
     The Company's revenue from software installation and implementation and
from contract services is generally recognized as the services are performed
using the percentage of completion method based on costs incurred to date
compared to total estimated costs at completion. Amounts received under
contracts in advance of performance are recorded as deferred revenue and are
generally recognized within one year from receipt. Contract losses are recorded
as a charge to income in the period such losses are first identified. Unbilled
accounts receivable are stated at estimated realizable value.
 
     Service bureau fees are from review and repricing of customers' medical
bills and are assessed to customers on the basis of volume of bills processed
and are recognized as revenue when the processing services are performed.
 
  Income Taxes
 
     The Company's current income tax expense is the amount of income taxes
expected to be payable for the current year. A deferred income tax asset or
liability is computed for the expected future impact of differences between the
financial reporting and tax bases of assets and liabilities as well as the
expected future tax benefit to be derived from tax loss and tax credit
carryforwards. Valuation allowances are established, when necessary, to reduce
deferred tax assets to the amount "more likely than not" to be realized in
future tax returns. Tax rate changes are reflected in income during the period
such changes are enacted.
 
  Net Income Per Common Share
 
     The Company adopted Statement of Financial Accounting Standard No. 128
("FAS 128"), "Earnings per Share," for fiscal 1997 and retroactively restated
all prior periods to conform with FAS 128 as required. Basic net income per
common share is computed as net income less accretion of dividends on
mandatorily redeemable convertible preferred stock divided by the weighted
average number of common shares outstanding during the period. Diluted net
income per common share is computed as net income divided by the weighted
average number of common shares and potential common shares, using the treasury
stock method, outstanding during the period and assumes conversion into common
stock at the beginning of each period of all outstanding shares of convertible
preferred stock (Note 8).
 
  Unaudited Pro Forma Data
 
     Prior to the acquisition of CompReview by HNC on November 28, 1997,
CompReview had elected subchapter S corporation status for income tax purposes;
therefore, its income was included in the tax returns of its stockholders, and
no income tax provision was recorded for CompReview other than certain minimum
state taxes on subchapter S corporations. As a result of the acquisition,
beginning November 29, 1997, CompReview became subject to corporate income taxes
on its taxable income. For comparative purposes, the consolidated statement of
income includes unaudited pro forma adjusted data with respect to the merged
companies' income tax provision as if CompReview had been subject to corporate
income taxes on its taxable income for all periods presented.
 
  Foreign Currency Translation
 
     The financial statements of the Company's international operations are
translated into U.S. dollars using period-end exchange rates for assets and
liabilities and average exchange rates during the period for revenues and
expenses. Cumulative translation gains and losses are excluded from results of
operations and recorded as a separate component of stockholders' equity. Gains
and losses resulting from foreign currency transactions (transactions
denominated in a currency other than the entity's local currency) are included
in the consolidated statement of income and are not material.

  Diversification of Credit Risk
 
     The Company's financial instruments that are subject to concentrations of
credit risk consist primarily of cash equivalents, investments available for
sale and accounts receivable, which are generally not collateralized. The
Company's policy is to place its cash, cash equivalents and investments
available for sale with high credit quality financial institutions and
commercial companies and government agencies in order to limit the amount of its
credit exposure. The Company's software license and installation agreements and
commercial development contracts are primarily with large customers in the
healthcare/insurance, financial services and retail industries. The Company
maintains reserves for potential credit losses.
 
     The Company has one major product or product line in each of its three
target markets. In the healthcare/insurance market, revenues from one product
accounted for 29.8%, 24.6% and 23.0% of the Company's total revenues for 1995,
1996 and 1997, respectively. During those same periods, one product in the
retail market accounted for 2.2%, 13.6% and 18.9%, respectively, of the
Company's total revenues, and one product line in the financial services market
accounted for 28.0%, 20.9% and 16.0%, respectively, of the Company's total
revenues. Revenues from international operations and export sales, primarily to
Western Europe and Canada, represented approximately 12.6%, 17.7% and 16.8% of
total revenues in 1995, 1996 and 1997, respectively. Export sales were $4,595,
$7,310 and $7,896 in 1995, 1996 and 1997, respectively.
 
  Disclosures About Fair Value of Financial Instruments
 
     The carrying amounts of cash and cash equivalents and accrued liabilities
approximate fair value because of the short-term maturities of these financial
instruments. The carrying amounts of capital lease obligations approximate their
fair values based on interest rates currently available to the Company for
borrowings with similar terms and maturities.
 
  Reincorporation and Stock Split
 
     In May 1995, the Company's stockholders approved an Agreement and Plan of
Merger whereby the Company merged with and into a newly incorporated Delaware
corporation ("HNC Delaware"), which is the surviving corporation. In conjunction
with the merger, each share of the Company's common stock, preferred stock and
options and warrants to purchase the Company's common stock was exchanged for
one-half share of HNC Delaware's common stock, preferred stock and options and
warrants to purchase HNC Delaware's common stock, at twice the exercise price
for options and warrants. In April 1996, the Company consummated a two-for-one
stock split effected in the form of a common stock dividend. All references to
share and per share amounts of common and preferred stock and other data in
these financial statements have been retroactively restated to reflect the
reincorporation and stock split.
 
  New Accounting Pronouncements
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130 ("FAS 130"), "Reporting
Comprehensive Income," which the Company is required to adopt for 1998. This
statement will require the Company to report in the financial statements, in
addition to net income, comprehensive income and its components including
foreign currency items and unrealized gains and losses on certain investments in
debt and equity securities. Upon adoption of FAS 130, the Company is also
required to reclassify financial statements for earlier periods provided for
comparative purposes. The adoption of FAS 130 will not have a significant impact
on the Company's consolidated financial statement disclosures.
 
     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131 ("FAS 131"), "Disclosures about Segments of an Enterprise and Related
Information," which the Company is required to
 
                                       45

                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
adopt for its 1998 annual financial statements. This statement establishes
standards for reporting information about operating segments in annual financial
statements and requires selected information about operating segments in interim
financial reports issued to stockholders. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. Under FAS 131, operating segments are to be determined consistent
with the way that management organizes and evaluates financial information
internally for making operating decisions and assessing performance. The Company
has not determined the impact of the adoption of this new accounting standard on
its consolidated financial statement disclosures.
 
   
     In October 1997, the American Institute of Certified Public Accountants
issued Statement of Position No. 97-2 ("SOP 97-2"), "Software Revenue
Recognition," which the Company is required to adopt for agreements entered into
with customers beginning in 1998. This statement provides guidance for software
revenue recognition matters primarily from a conceptual level and does not
include specific implementation guidance. Based on its reading and
interpretation of SOP 97-2, the Company believes that the adoption of SOP 97-2
will not have a significant impact on its financial statements; however,
detailed implementation guidelines for this standard have not yet been issued.
Once issued, such detailed implementation guidance could lead to unanticipated
changes in the Company's current revenue recognition practices, and such changes
could be material to the Company's financial statements.
    
 
  Reclassifications
 
     Certain prior year balances have been reclassified to conform to the
current year presentation.

NOTE 4 -- NOTES PAYABLE
 
     The Company has a Credit Agreement with a bank which provides for a $15,000
revolving line of credit through July 11, 1999. The agreement requires that the
Company maintain certain financial ratios and levels of working capital,
tangible net worth and profitability, and also restricts the Company's ability
to pay cash dividends and make loans, advances or investments without the bank's
consent. At December 31, 1997, the Company had no amounts outstanding under the
revolving line of credit. Interest is payable monthly at the bank's prime rate
or LIBOR rate plus 1.5%. The applicable interest rate was 7.22% at December 31,
1997.
 
     The Risk Data credit facilities were comprised of a revolving line of
credit secured by eligible accounts receivable, as well as a bridge loan that
was secured by the guarantees of certain stockholders. The revolving line of
credit matured on January 5, 1997. The bridge loan matured on September 5, 1996.
All outstanding amounts were repaid during 1996, and neither credit facility was
renewed.

     During 1995, the preferred stockholders of Risk Data loaned the Company
$1,000 under subordinated note agreements (secured by the assets of Risk Data
but subordinated to borrowings under the Risk Data line of credit) bearing
interest at 9%. All outstanding amounts were repaid during 1996.

     The lease for the Company's corporate headquarters provides for scheduled
rent increases and an option to extend the lease for five years with certain
changes to the terms of the lease agreement and a refurbishment allowance. Rent
expense under operating leases for the years ended December 31, 1995, 1996 and
1997 was approximately $1,503, $1,623 and $2,687, respectively, net of sublease
income of $83, $125 and $477, respectively.
 
     Risk Data maintains a lease line of credit with a leasing company for the
acquisition of equipment under capital lease arrangements. Future minimum
payments are $222 for 1998 and $66 for 1999 with a total of $34 of such amounts
representing interest.
 
     The gross value of assets under capital leases at December 31, 1996 and
1997 was $1,481 and $714, and accumulated amortization was $599 and $556,
respectively. Amortization expense for assets acquired under capital leases is
included in depreciation expense.
 
NOTE 6 -- CAPITAL STOCK
 
     During June 1995, the Company completed its initial public offering of
5,176 shares of common stock (of which 2,376 shares were sold by the Company and
2,800 shares were sold by certain selling stockholders) at a price to the public
of $7.00 per share, which resulted in net proceeds to the Company of $15,461
after the payment of underwriters' commissions but before the deduction of
offering expenses. Upon the closing of the Company's initial public offering,
all outstanding shares of Series A, B, C, D and E convertible preferred stock
were automatically converted into shares of common stock at their then effective
conversion prices. Upon conversion, the preferred stockholders were no longer
entitled to any undeclared cumulative dividends and all class voting rights
terminated.
 
     During December 1995, the Company completed a follow-on public offering of
3,000 shares of common stock (of which 1,116 shares were sold by the Company and
1,884 shares were sold by certain selling stockholders) at a price to the public
of $18.50 per share, which resulted in net proceeds to the Company of $19,606
after the payment of underwriters' commissions but before the deduction of
offering expenses.
 
     The Company's Board of Directors is authorized to issue up to 4,000 shares
of preferred stock and to determine the price, rights, preferences, privileges
and restrictions, including voting rights, of those shares

Company released the valuation allowances related to Risk Data's and Retek's
deferred tax assets based on management's assessment that it was more likely

     During 1995, 1996 and 1997, the Company realized certain tax benefits
related to stock option transactions in the amount of $800, $7,889 and $4,192,
respectively. The benefit from the stock option tax deduction is credited
directly to paid-in capital.
 
     During 1996, in connection with the acquisition of Retek, the Company made
an Internal Revenue Code Section 338 election for federal and state tax
purposes, resulting in the treatment of the acquisition as a taxable
transaction, whereby the tax bases of the acquired assets and liabilities were
adjusted to their fair values as of the date of the acquisition. As the purchase
price exceeded the carrying value of the net assets acquired by approximately
$46,000, the Company recorded a deferred tax asset in the amount of $18,397.
 
     A reconciliation of the income tax (benefit) provision to the amount
computed by applying the statutory federal income tax rate to income before
income tax provision is summarized as follows:

     Prior to the acquisition of CompReview by the Company on November 28, 1997,
CompReview had elected subchapter S corporation status and the cash basis of
accounting for income tax purposes; therefore, its cash basis income was
included in the tax returns of its stockholders, and no income tax provision was
recorded for CompReview other than certain minimum state taxes on subchapter S
corporations. As of the date of CompReview's acquisition, its tax status was
changed to C corporation status with the accrual basis of accounting. As a
result of this change in tax status, the Company recorded a deferred tax
liability in the amount of $869 based on the cumulative income recognition
differences as of the date of acquisition between CompReview's former and
prospective tax accounting methods.
 
     At December 31, 1997, the Company had federal, state and foreign net

also are limited to utilization solely by the company that generated them.
Should a substantial change in HNC's ownership occur, as defined by the Tax
Reform Act of 1986, there will be an annual limitation on its utilization of net

NOTE 9 -- EMPLOYEE BENEFIT PLANS
 
     During 1987, the Company adopted the 1987 Stock Option Plan and reserved
2,500 shares of the Company's common stock for issuance pursuant to nonqualified
and incentive stock options to its officers, directors, key employees and
consultants. The plan, as amended, is administered by the Board of Directors or
its designees and provides generally that, for incentive stock options and
nonqualified stock options, the exercise price must not be less than the fair
market value of the shares as determined by the Board of Directors at the date
of grant. The options expire no later than ten years from the date of grant and
may be exercised in installments based upon stipulated timetables (not in excess
of seven years). At December 31, 1997, options to purchase 490 shares were
exercisable.
 
     During 1995, the Company adopted the 1995 Directors Stock Option Plan (the
"Directors Plan"), the 1995 Equity Incentive Plan (the "Incentive Plan") and the
1995 Employee Stock Purchase Plan (the "Purchase Plan"). For purposes of the
discussion contained in the three paragraphs below, "fair market value" means
the closing price of the Company's common stock on the Nasdaq National Market on
the grant date.
 
     The Directors Plan provides for the issuance of up to 300 nonqualified
stock options to the Company's outside directors. Under the provisions of the
Directors Plan, options to purchase 25 shares of the Company's common stock are
granted to outside directors upon their respective dates of becoming members of
the Board of Directors and options to purchase ten shares of such stock will be
granted on each anniversary of such dates.

Options under the Directors Plan are granted at the fair market value of the
stock at the grant date and vest at specific times over a four-year period. At
December 31, 1997, options to purchase 72 shares were exercisable.
 
     The Incentive Plan provides for the issuance of up to 3,550 shares of the
Company's common stock in the form of nonqualified or incentive stock options,
restricted stock or stock bonuses. In addition, all shares that remained
unissued under the 1987 Stock Option Plan on the effective date of the Incentive
Plan, and all shares issuable upon exercise of options granted pursuant to the
1987 Stock Option Plan that expire or become unexercisable for any reason
without having been exercised in full are available for issuance under the
Incentive Plan. Nonqualified stock options and restricted stock may be awarded
at a price not less than 85% of the fair market value of the stock at the date
of the award. Incentive stock options must be awarded at a price not less than
100% of the fair market value of the stock at the date of the award. Options
granted under the Incentive Plan may have a term of up to ten years. The Company
has the discretion to provide for restrictions and the lapse thereof in respect
of restricted stock awards. Options typically vest at the rate of 25% of the
total grant per year over a four-year period; however, the Company may, at its
discretion, implement a different vesting schedule with respect to any new stock
option grant. At December 31, 1997, 316 shares were exercisable.
 
     The Purchase Plan provides for the issuance of a maximum of 400 shares of
common stock. Each purchase period, eligible employees may designate between 2%
and 10% of their cash compensation, subject to certain limitations, to be
deducted from their compensation for the purchase of common stock under the
Purchase Plan. The purchase price of the shares under the Purchase Plan is equal
to 85% of the lesser of the fair market value per share on the first day of the
twelve-month offering period or the last day of each six-month purchase period.
Approximately 60% of eligible employees have participated in the Purchase Plan
in the last two years.
 
     Risk Data's stock option plan is administered by HNC's Board of Directors.
All outstanding Risk Data options were converted into options to purchase HNC
common stock and adjusted to give effect to the acquisition exchange ratio in
the Risk Data acquisition. No changes were made to the terms of the Risk Data
options in connection with the exchange. Options granted under the Risk Data
stock option plan generally vest at the rate of 25% of the total grant per year
and expire ten years after the date of grant. At December 31, 1997, 30 shares
were exercisable under the Risk Data plan.
 
     Retek's stock options are administered by HNC's Board of Directors. All
outstanding Retek options were converted into options to purchase the Company's
common stock and adjusted to give effect to the acquisition exchange ratio in
the Retek acquisition. No changes were made to the terms of the Retek options in
connection with the exchange. Options granted vest ratably over periods from one
to four years and have a term of up to ten years. At December 31, 1997, options
to purchase 32 shares were exercisable.
 
     The CompReview 1995 Stock Option Plan is administered by HNC's Board of
Directors. All outstanding CompReview stock options were converted into options
to purchase HNC common stock in the CompReview acquisition and adjusted to give
effect to the acquisition exchange ratio. No changes were made to the terms of
the CompReview options in connection with the exchange. Options granted under
the CompReview Stock Option Plan generally vest ratably over periods from two to
four years and expire ten years after the date of grant. At December 31, 1997,
options to purchase 156 shares were exercisable.

     During 1996, Aptex adopted the 1996 Equity Incentive Plan (the "Aptex
Plan") whereby 2,000 shares of Aptex common stock were reserved for issuance
pursuant to nonqualified and incentive stock options and restricted stock
awards. The plan is administered by the Board of Directors of Aptex or its
designees and provides generally that nonqualified stock options and restricted
stock may be awarded at a price not less than 85% of the fair market value, as
determined by the Board of Directors, of the stock at the date of the award.
Incentive stock options must be awarded at a price not less than 100% of the
fair market value of the stock at the date of the award, or 110% of fair market
value for awards to more than 10% stockholders. Options granted under the
Incentive Plan may have a term of up to ten years. The Company has the
discretion to provide for restrictions and the lapse thereof in respect of
restricted stock awards, and options typically vest at the rate of 25% of the
total grant per year. However, the Company may, at its discretion, implement a
different vesting schedule with respect to any new stock option grant. During
1996, Aptex issued 1,000 shares of common stock at fair market value under the
Aptex Plan for cash consideration of $0.03 per share. At December 31, 1997,
options to purchase 79 shares were exercisable under the Aptex Plan.

     The Company applies Accounting Principles Board Opinion No. 25 and related
Interpretations in accounting for its stock-based compensation. No compensation
expense has been recognized for its employee stock option grants, which are
fixed in nature, as the options have been granted at fair market value. No
compensation expense has been recognized for the Purchase Plan. Had compensation
cost for the Company's stock-based compensation awards issued during 1997 and
1996 been determined based on the fair value at the grant dates of awards
consistent with the method of Financial Accounting Standards Board Statement No.

     The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted average
assumptions used for grants during the years ended December 31, 1995, 1996 and
1997, respectively: dividend yield of 0.0% for all three years, risk-free
interest rates of 6.29%, 6.03% and 6.10%, expected volatilities of 75%, 70% and
65% (0% for 1995 and 1996 options granted by Risk Data, Retek and CompReview
prior to their acquisition by HNC), and expected lives of 3.5, 3.5 and 3.0
years. The fair value of the employees' purchase rights pursuant to the Purchase
Plan is estimated using the Black-Scholes model with the following assumptions:
dividend yield of 0.0% for all three years, risk-free interest rates of 5.66%,
5.36% and 5.32%, expected volatilities of 75%, 70% and 65%, and an expected life
of 6 months for all three years. The weighted average fair value of those
purchase rights granted in 1995, 1996 and 1997 was $2.75, $9.61 and $14.10,
respectively.
 
     The fair value of each option granted under the Aptex Plan is estimated on
the date of grant using the Black-Scholes option pricing model with the
following weighted average assumptions used for grants during the years ended
December 31, 1996 and 1997: dividend yield of 0.0% for both years, risk-free
interest rates of 6.42% and 6.33%, expected volatility of 90% for both years,
and expected lives of 9.25 and 8.0 years. Options to purchase 704 shares and 214
shares were granted during 1996 and 1997, with weighted average exercise prices
per share of $0.03 and $0.08, respectively. During 1997, options to purchase 173
shares with a weighted average exercise price of $0.03 per share were exercised.
During 1997, options to purchase 58 shares with a weighted average exercise
price of $0.03 per share were cancelled. The weighted average fair value per
share of options granted during 1996 and 1997 was $0.03 and $0.07, respectively.

NOTE 10 -- CONTINGENCIES
 
     Various claims arising in the course of business, seeking monetary damages
and other relief, are pending. The amount of the liability, if any, from such
claims cannot be determined with certainty; however, in the opinion of
management, the ultimate liability for such claims will not have a material
adverse effect on the Company's consolidated financial position, results of
operations or cash flows.
 
NOTE 11 -- SUBSEQUENT EVENTS
 
     On January 30, 1998, the Company signed a definitive agreement to acquire
Practical Control Systems Technologies, Inc. ("PCS"), a distribution center
management software vendor based in Cincinnati, Ohio, subject to the
satisfaction of certain closing conditions and the approval of PCS'
shareholders. If consummated, the acquisition of PCS will be accounted for under
the purchase method and will not be considered a "significant" acquisition
pursuant to regulations set forth by the Securities and Exchange Commission.
 
     On February 13, 1998, the Company adopted the 1998 Stock Option Plan (the
"1998 Plan"), under which 1,000,000 shares of HNC Common Stock were reserved for

                                      TERM

     3.1 TERM: The Term of this Lease is set forth in Section 1.5. "Expiration
Date" shall mean the last day of the initial Term. The Commencement Date and
Expiration Date shall be confirmed in writing by Landlord and Tenant within
fifteen (15) days after the Commencement Date.

     3.2 OPTION TO EXTEND TERM:

         (a) Option to Extend Term: As a material part of the consideration for
the execution of this Lease by Tenant, Tenant is hereby granted an option to
extend the Term for one (1) five (5) year period ("Extended Term") following the
Expiration Date, by giving Landlord written notice of Tenant's exercise of the
option and setting forth the agreed upon or arbitrator-determined Base Rent for
the Extended Term, ("Option Notice") at least nine (9) months before the
Expiration Date or otherwise in accordance with the provisions of Section 4.3
below. The option to extend the Term shall be for all, or any full floor
portion, of the Premises. If the option to extend is exercised, the "Option
Commencement Date" shall be one day after the Expiration Date and the term of
this Lease shall be extended to the fifth anniversary of the Expiration Date
("Option Expiration Date").

         (b) Provisions Applicable to the Option: The option to extend set forth
in the preceding paragraph may be exercised by Tenant provided that, at the time
Landlord receives the Option Notice, Tenant is not in material default under
this Lease. Notwithstanding Section 3.2(a), if Tenant is in material default of
this Lease on the date Landlord receives the Option Notice, the Option Notice
shall be void and the Extended Term shall not commence unless Landlord notifies
the Tenant in writing within ten (10) days after receipt of the Option Notice
that the Option Notice is accepted and will operate to extend the Term. If
Tenant is in material default under this Lease on the date the Extended Term is
to commence and Tenant has not commenced any cure of such default within the
cure periods set forth in Section 12 below, then, in Landlord's sole election,
the Extended Term shall not commence and this Lease shall expire upon the
Expiration Date. Tenant shall in no event be deemed in default if curative
action has occurred pursuant to Section 12.

         (c) Provisions Applicable To The Extended Term: The Extended Term shall
be upon the same terms and conditions as set forth in this Lease except as
follows:

              (i) The Base Rent for the Extended Term shall be adjusted to
ninety-five percent (95%) of the then-fair market rental value as more
specifically set forth in Section 4.3 below.

              (ii) Tenant will have no option to extend the Term of this Lease
beyond the Option Expiration Date.

              (iii) Tenant shall accept the Premises in its then "AS IS"
condition at the Option Commencement Date.

              (iv) If the Lease is extended, then "Term" as used in this Lease
shall include the Term and the Extended Term unless specifically provided to the
contrary.

              (v) Within thirty (30) days after Tenant's delivery of an Option
Notice setting forth the agreed-upon Base Rent or arbitrator-determined Base
Rent for the Extended Term, the parties shall execute an amendment to this Lease
stating the new monthly Base Rent for the Extended Term, provided, however, that
the execution of such amendment shall not be a condition precedent to Tenant's
obligation to pay increased Base Rent.

                                    SECTION 4
                                      RENT

demand (except as specifically set forth in this Lease and except for tenant

     4.3 RENT FOR EXTENDED TERM: The rent for the Extended Term shall be
Ninety-five Percent (95%) of the Fair Market Rental Value of the Premises, as
defined in Section 4.4. On or before the date which is Fourteen (14) months
prior to the Expiration Date, Landlord shall notify Tenant in writing of
Landlord's determination of Fair Market Rental Value. Tenant may, at its
election, either accept such determination of Fair Market Rental Value or
attempt to reach an alternative determination of Fair Market Rental Value by
mutual agreement with Landlord. If Landlord and Tenant are unable to agree on
the Fair Market Rental Value within thirty (30) days after Tenant's receipt of
the Landlord's Notice, then the Fair Market Rental Value shall be determined in
accordance with the following procedure: Within forty (40) days after Tenant's
receipt of Landlord's notice, Landlord and Tenant shall jointly appoint an
arbitrator and an alternate arbitrator in accordance with the commercial
arbitration rules of the American Arbitration Association. Such arbitrator and
alternate arbitrator shall be experienced with matters involving real estate
appraisals in the area in which the Premises are located. Concurrent with such
appointments, Landlord and Tenant shall each submit to such arbitrator their
respective determination of the Fair Market Rental Value and such arbitrator
shall select the one of such two submitted determinations that is closest to
such arbitrator's own appraisal of the Fair Market Rental Value. Such arbitrator
shall have no discretion to make any determination other than the selection of
either Landlord or Tenant's determination of Fair Market Rental Value. The cost
of such arbitrator shall be shared equally by Landlord and Tenant. Landlord and
Tenant shall each proceed expeditiously with the arbitration in order to permit
the arbitrator's decision to be issued at least Three hundred forty (340) days
prior to the Expiration Date. If the arbitrator's decision has not been received
by the Tenant and the Landlord three hundred forty (340) days prior to the
Expiration Date it shall be void unless the parties agree in writing otherwise,
and Landlord and Tenant shall each, three hundred and thirty (330) days prior to
the Expiration Date, submit to the alternate arbitrator their respective
determination of Fair Market Rental Value and the alternate arbitrator shall
select the one of such two submitted determinations that is closest to such
alternate arbitrator's own appraisal of the Fair Market



<PAGE>   11



Rental Value. Such alternate arbitrator shall have no discretion to make any
determination other than the selection of either Landlord or Tenant's
determination of Fair Market Rental Value. The cost of such alternate arbitrator
shall be shared equally by Landlord and Tenant. Landlord and Tenant shall each
proceed expeditiously with the arbitration in order to permit the alternate
arbitrator's decision to be issued at least two hundred eighty (280) days prior
to the Expiration Date. In the event that the arbitrator's decision is not
received by Tenant on or before such date, Tenant shall nevertheless have a
period of ten (10) days following such receipt to determine whether to send the
Option Notice to Landlord, exercising Tenant's right to extend. If Tenant does
not so extend, the Term shall be extended by a number of days equal to Two
Hundred Seventy (270), minus the number of days remaining in the Term when the
Tenant's right to send the Option Notice expired, divided by two (2).

     4.4 "FAIR MARKET RENTAL VALUE" shall mean the effective value on a monthly
basis of all expenditures for comparable office space being paid by willing,
comparable non-renewal tenants with a credit standing and financial stature
equivalent to Tenant, giving appropriate consideration to all relevant economic
terms and conditions of the Landlord/Tenant relationship, including without
limitation tenant improvement, refurbishment and other allowances, operating
expense stops or caps, leasing and other commissions (whether paid to
independent parties, to Landlord or to affiliates of Landlord), parking charges
or abatements, rental abatements, signing bonuses and similar cash or
cash-equivalent tenant concessions. For purposes of determination of Fair Market
Rental Value, other comparable space in the Project shall be considered the most
comparable space to the Premises and Landlord shall be obligated to furnish to
Tenant and any arbitrator copies of all leases of other space in the Project,
certified to contain all relevant information with regard to the economic
transaction between Landlord and the tenant thereunder. Other than the Project,
Landlord and Tenant acknowledge that the most comparable buildings to the
Building to be considered in determination of Fair Market Rental Value are set
forth in Exhibit "P", however other comparable buildings in the general area may
be considered.

     4.5 SECURITY DEPOSIT AMOUNT: Upon the execution of this Lease, Tenant shall
deposit with Landlord cash or a check in the amount of the Security Deposit
Amount to secure the performance by Tenant of its obligations under this Lease,
including without limitation Tenant's obligations to (a) pay Rent, (b) repair
damages to the Premises caused by Tenant, Tenant's agent(s), employee(s),
officer(s) and/or independent contractor(s) of or retained by Tenant ("Tenant's
Representatives"), and/or Tenant's guests, visitors, customers, invitees and/or
licensees ("Tenant's Invitees"), (c) clean the Premises upon termination of this
Lease, and (d) remedy future defaults by Tenant in any obligation under this
Lease to restore, replace or return personal property installed or located in or
on the Premises including without limitation trade fixtures, furnishings,
equipment and inventory, signs, satellite dish ("Personal Property") or
appurtenances. If Tenant defaults under this Lease, including without limitation
a default described in the preceding sentence, Landlord may use the security
deposit to cure such defaults and to compensate Landlord for all or a portion of
Landlord's damage resulting from such defaults. Upon demand by Landlord, Tenant
shall promptly pay to Landlord a sum equal to the amount so used by Landlord so
as to replenish the Security Deposit Amount. Within thirty (30) days after the
Expiration Date, Option Expiration Date or earlier termination of this Lease,
Landlord shall deliver to Tenant, at Tenant's address, any portion of such
Security Deposit Amount not used by Landlord, together with a detailed statement
explaining how any portion of the Security Deposit Amount was used. Landlord may
commingle such Security Deposit Amount with Landlord's other funds and Landlord
shall not pay to Tenant interest on such Security Deposit Amount. In the event
of a bankruptcy or other insolvency or a debtor-creditor proceeding against or
by Tenant, the Security Deposit Amount shall be deemed applied first to the
payment of Rent and other amounts due Landlord for all periods prior to the date
of filing or instigating such proceedings. To the extent any debts, liabilities
and obligations of Tenant under this Lease have not been satisfied, Tenant shall
remain fully liable to Landlord for their payment and/or performance. Provided
that Tenant has not been in default under this Lease beyond the cure period set
forth in Section 12 below during the first sixty (60) months of the Term,
Landlord shall return to Tenant the Security Deposit Amount at the end of such
sixty (60) month period.

         (h) "Real Property Taxes" shall mean all real property taxes and

including without limitation any tax, fee or excise on (i) rents, (ii) the

property taxes or general or special assessments. Notwithstanding anything to
the contrary in the preceding sentence, "Real Property Taxes" shall not mean any
municipal, county, state, or federal income, franchise, estate, succession,
inheritance or transfer taxes of Landlord. If any Real Property Taxes are

or transfer of or change of ownership in the Project (or any part thereof) which

assessed in combination with the Adjacent Building, then (for purposes of
determining Building Operating Expenses and Common Area Operating Expenses) the
Real Property Taxes shall be allocated on the basis of the ratio of the Rentable
Square Footage to the Project Rentable Area.

     6.2 ADJUSTMENTS TO COMMON AREA OPERATING EXPENSES: Common Area Operating
Expenses during the Term (including the Base Year) shall be "grossed up" ("Gross
Up") if the Project is less than ninety-five percent (95%) leased and occupied,
in accordance with reasonable and generally accepted accounting principles
consistently applied to reflect what Common Area Operating Expenses would have
been had the Project been ninety-five percent (95%) leased and occupied and
fully assessed for tax purposes as leased and occupied buildings. In no event
shall the Gross Up result in Landlord receiving payment or reimbursement from
Tenant for costs or expenses not actually incurred by Landlord.

     6.3 RENT ADJUSTMENT: If Lease Expenses for any Lease Year are greater than
Lease Expenses for the Base Year (after the Gross Up of Common Area Operating
Expenses), Tenant shall pay such increase in Lease Expenses pursuant to this
Section 6.3. Landlord shall deliver to Tenant, at least thirty (30) days prior
to the commencement of each subsequent Lease Year during the Term, a written
statement ("Estimated Statement") setting forth Landlord's estimate of the
amount by which the Lease Expenses for the upcoming Lease Year will be greater
or less than the Lease Expenses for the Base Year (the "Lease Expenses
Difference"). If the Lease Expenses for the upcoming Lease Year are estimated to
be greater than the Lease Expenses for the Base Year, then Tenant shall pay to
Landlord, on the first day of each month during the Term, an amount ("Monthly
Payment") equal to one-twelfth (1/12th) of the Lease Expenses Difference, as
estimated by Landlord in the most recently delivered Estimated Statement.
Landlord may, at its election, no more than one (1) time during any Lease Year,
deliver to Tenant a revised Estimated Statement, revising Landlord's estimate of
the Lease Expenses, in accordance with Landlord's most current estimate. No
later than one hundred twenty (120) days after the end of each Lease Year,
Landlord shall deliver to Tenant a written statement ("Actual Statement")
setting forth the actual Lease Expenses Difference allocable to such Lease Year.
If the sum of Monthly Payments actually paid by Tenant during any Lease Year
exceeds the actual Lease Expenses Difference allocable to such Lease Year, then
such excess shall be refunded to Tenant within thirty (30) days after delivery
of the Actual Statement to Tenant. If Tenant has made Monthly Payments and the
sum of Monthly Payments actually paid by Tenant during any Lease Year is less
than the actual Lease Expenses Difference allocable to such Lease Year, then
Tenant shall, within thirty (30) days after receipt of the Actual Statement, pay
to Landlord the amount of such deficiency. The payment by Tenant of any Monthly
Payment or any year-end deficiency of Lease Expenses Difference shall not be
deemed a waiver of Tenant's right to contest Landlord's calculation of Lease
Expenses.

     6.4 LEASE EXPENSES DIFFERENCE CAP: Notwithstanding anything to the contrary
in this Lease, Lease Expenses Difference shall not include more than one hundred
eight percent (108%) of Controllable Operating Expenses of the preceding Lease
Year, or in the case of the first Lease Year, the Base Year. "Controllable
Operating Expenses" shall mean landscaping maintenance, parking lot sweeping,
plumbing, Tri-Water System maintenance, janitorial services and supplies, trash
removal, security and life safety, pest control, elevator maintenance, parking
and walkways, locks and keys, window washing, lighting


<PAGE>   17


maintenance, roof maintenance, painting and sealing, general maintenance, paving
maintenance, windows, doors and screens, signs, common area maintenance, and
management fees.

     6.5 OPERATING EXPENSE RECORDS: Landlord shall maintain all operating
expense records for a period of five (5) years. Tenant or Tenant's
Representative shall have the right to inspect and photocopy any or all of the
operating expense records at the office of PacCor Management Company during
normal working hours upon twenty-four (24) hours written notice. Tenant shall
have the right to require an audit of Lease Expenses. In the event Tenant's
audit determines that Lease Expenses Difference for any Lease Year is overstated
by Twelve Thousand Five Hundred Dollars ($12,500.00) or more, then Landlord
shall pay for the cost of such audit unless the Actual Statement fairly
disclosed the facts underlying the overstatement. The $12,500.00 shall be
adjusted each Lease Year to reflect the increase, if any, in the cost of living
during the previous Lease Year by increasing the $12,500 by the percentage by
which the level of the Consumer Price Index (for all urban consumers in San
Diego areas as reported for the date of an audit pursuant to this Section 6.5 by
the Bureau of Labor Statistics of the United States Department of Labor) has
increased over the level as of the date of the execution of this Lease. Any
amounts of Lease Expenses Difference overpaid by Tenant shall be immediately
refunded or shall be credited against the Base Rent next due by Tenant.

                                    SECTION 7
                       USE AND MAINTENANCE OF THE PREMISES

     7.1 PERMITTED USE: Tenant may use the Premises for general office use and
for any other legally permitted use compatible with comparable office buildings
in the Sorrento Mesa area of San Diego, California.

     7.2 INSURANCE: Tenant shall not do, bring or keep anything in or about the
Premises which is outside the scope of that which is normally contemplated for
the use specified in Section 7.1, that will cause a cancellation of any
insurance covering the Premises or the Project. If the rate of any insurance
carried by Landlord is increased as a result of Tenant's use (except as
contemplated by Section 7.1), Tenant shall pay to Landlord, within ten (10) days
after Landlord delivers to Tenant a notice of such increases, the amount of such
increase.

represents and warrants that, as of the date of this Lease, there are no
violations within the Project of the Americans With Disabilities Act 42 U.S.C.
Section 1281 et. seq. ("ADA") and any similar state and federal laws. To the
extent that the foregoing representation and warranty is inaccurate or untrue,

ordinance or rule or by any governmental agency with respect to the use,
generation, treatment, storage, disposal, release or threatened release of
hazardous, toxic or radioactive substance, materials or waste (collectively

the State to cause cancer or reproductive toxicity," "asbestos," "hydrocarbons
(including without limitation oil)," "toxic bearing dust" or other similar
designations in the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, 42 U.S.C. Sections 9601, et seq., the

the Safe Drinking Water and Toxic Enforcement Act of 1986, Health & Safety Code
Sections 25249.5, et seq., and any other federal, state or local statutes, laws,
ordinances, rules, regulations and precautions. Tenant shall not cause or allow
any other party or parties to cause any Hazardous Materials to be used,
generated, treated, stored, disposed of or released in, on or about the
Premises, except as allowed by law. Tenant shall indemnify, protect, defend by
counsel acceptable to Landlord, and hold Landlord and its successors, assigns
and mortgagees harmless from and against any and all claims, losses,
liabilities, costs and expenses, including all foreseeable and unforeseeable
consequential damages, except to the extent caused by Landlord's or Landlord's
Representative's negligence, willful misconduct or breach of obligations under
this Lease, directly or indirectly arising out of the use, generation,
treatment, storage, disposal, release or threatened release of Hazardous
Materials by Tenant or any party or parties claiming under Tenant of Hazardous
Materials at, on, beneath or from the Project based on the Comprehensive
Environmental Response, Compensation and Liability Act, 42 U.S.C. Sections 9601,
et seq., the Resource Conservation and Recovery Act, 42 U.S.C. Sections 6901, et
seq., the California Hazardous Substance Account Act, Health & Safety Code

Representatives (as defined in 4.5) and Tenant's successors, assigns and
mortgagees harmless from and against any and all claims, losses, liabilities,
costs and expenses, including all foreseeable and unforeseeable consequential

Safety Code Sections 25300, et seq., the California Hazardous Waste Control Law,
Health & Safety Code Sections 25100, et seq., the Porter-Cologne Water Quality
Control Act, Water Code Sections 13000, et seq., or any other federal, state or
local statute, law, regulation, ordinance or rule. Neither the written consent
by Landlord to the use, generation, storage or disposal of Hazardous Materials
nor the strict compliance by Tenant with all statutes, laws, ordinances, rules,
regulations and precautions pertaining to Hazardous Materials shall excuse
Tenant from Tenant's obligations pursuant to this Section 7.4. Tenant's
obligations pursuant to this Section 7.4 shall survive the termination of this
Lease. Tenant shall notify Landlord, as required by California Health & Safety
Code Section 25359.7, if Tenant knows or has reasonable cause to believe that
any Hazardous Material has come to be located on or beneath the Building. On or
before January 1, 1995, and each January 1 thereafter during the Term, Tenant
shall provide Landlord with a written list of all Hazardous Materials used,
generated, treated, stored, disposed of and released in, on or about the
Premises by Tenant during the prior calendar year and those Hazardous Materials
Tenant proposes to use, generate, treat, store, dispose of and release during
the next calendar year, except for substances which are customarily used or
found in typical offices, including without limitation copier and printer toner,
cleaning supplies, correction fluid and ink.

     7.5 DAMAGE AND OVERLOADING: Tenant shall be responsible for any damage to
the Premises or the Project caused by Tenant's Invitees and/or Tenant's
employees. Landlord represents to Tenant that the correct floor loads for the
Building are set forth in Exhibit "M". Neither the floor nor any other portion
of the Premises shall be loaded more than set forth in Exhibit "M". No
machinery, apparatus, or other appliance shall be used or operated in or on the
Premises that will in any manner injure the Premises or Project. If Tenant,
Tenant's Representatives or Tenant's Invitees cause damage to the Premises or
the Project, then Landlord shall have the right but not the obligation to repair
such damage and Tenant shall promptly reimburse Landlord for Landlord's actual
costs of such repair (to the extent that such costs exceed available insurance
proceeds) as Rent.

     7.6 ACCESS BY LANDLORD:

         (a) Landlord and/or Landlord's agent(s), employee(s), officer(s) or
independent contractor(s) of or retained by Landlord ("Landlord's
Representatives") shall have the right to enter the Premises at all


<PAGE>   19


reasonable times upon twenty-four (24) hour prior written notice (i) to
determine whether the Premises are in Good Condition (as defined in Section
7.15) or whether Tenant is complying with its obligations under this Lease, (ii)
to do any necessary maintenance or make any restoration to the Premises that the
Landlord has the right or obligation to perform, (iii) to serve, post, or keep
posted any notices required or allowed under this Lease, (iv) to show the
Premises to brokers, agents, buyers, tenants or other persons interested in a
listing of, financing, sale or exchange of, or occupancy of the Premises or the
Project, and (v) to shore the foundations, footings, and walls of the Premises
and other improvements on the Real Property and to erect scaffolding and
protective barricades around and about the Premises or the Project, but not so
as to prevent entry to or use of the Premises and to do any other act or thing
necessary for the safety or preservation of the Premises or the Project if any
excavation or other construction is undertaken or is about to be undertaken on
any adjacent property or nearby street. Landlord shall have the right at any and
all times to enter the Premises for emergency purposes.

         (b) Landlord shall not be liable for any inconvenience, disturbance,
loss of business, nuisance, or other damage arising out of Landlord's entry on
the Premises as provided in this Section 7.6, except damage resulting directly
from the negligent act or willful misconduct of Landlord or Landlord's
Representatives. No provision of this Lease shall be construed as obligating
Landlord to perform any repairs, alterations or decorations except as otherwise
expressly agreed in writing to be performed by Landlord. Landlord shall have the
right to run utility or other services and facilities through the Premises
whether to service the Premises or other premises, provided that the use of such
space does not have a materially adverse effect on Tenant's use and enjoyment of
the Premises. If during the last month of the Term, Tenant shall have removed
substantially all of its Personal Property and personnel from the Premises,
Landlord may enter the Premises and repair, alter and redecorate the same
without abatement of Base Rent or liability to Tenant and such acts shall have
no effect on this Lease. Any entry to the Premises obtained by Landlord pursuant
to this Section 7.6 shall not under any circumstances be construed or deemed to
be a forcible or unlawful entry into of the Premises, or an eviction of Tenant
from the Premises or any portion thereof. Tenant shall not be entitled to an
abatement or reduction of Base Rent because of the exercise by Landlord of any
rights under this Section 7.6. Landlord shall conduct its activities on the
Premises as allowed in this Section 7.6 in a manner that will cause as little
inconvenience, annoyance, or disturbance to Tenant as reasonably feasible.

     7.7 SIGNS: Tenant shall have the right to place, construct and maintain one
or more signs, monuments, logos or emblems at the entrance to the Project, near
the top of the Building, on the directory, near the entrance to the Building
and/or on entrance doors of the Premises, as set forth in Exhibit "L" ("Signs").
Modifications to Signs shall be subject to Landlord's written approval, which
approval will not be unreasonably withheld. The design, construction and
maintenance of Signs shall be solely at Tenant's expense. Landlord makes no
representation with respect to Tenant's ability to obtain such approvals under
applicable laws and regulations or pursuant to that certain Declaration of
Covenants, Conditions and Restrictions for Unit No. 1 of Pacific Corporate
Center, dated May 14, 1985 and recorded as Instrument #85-169398 ("CC&R's";
Exhibit "K"). In any event, Signs shall comply with all laws, regulations,
CC&R's, and PID (Exhibit "N"). Tenant shall obtain any approvals required by
laws, regulations and CC&R's. All costs to remove all Signs upon the Expiration
Date, Option Expiration Date or earlier termination of the Lease shall be the
liability of Tenant.

     7.8 PARKING: Subject to the terms of this Section 7.8 and so long as Tenant
is not in default under this Lease, Landlord grants to Tenant the right to the
non-exclusive use in common with other Project tenants of the parking lot
adjacent to and serving the Building of One Hundred Eighty Two (182) parking
spaces(except that there shall be reserved for the use of Tenant's visitors and
executives the twelve (12) parking spaces in front of the Building). Tenant's
use of the parking lot shall be subject to such reasonable rules which do not
favor other Project tenants to the detriment of Tenant, as Landlord may, in its
sole discretion, adopt from time to time with respect to use of the parking lot.
Landlord shall cooperate with Tenant, and shall take all reasonable steps
necessary, to ensure that Tenant and Tenant's Representatives and Tenant's
Invitees shall have access to all one hundred eighty-two (182) parking spaces to
which Tenant is entitled. Tenant shall not be charged for the use of the parking
lot unless the City of San Diego or other governmental entity after the
execution of this Lease assesses a tax, fee and/or excise on the parking of
motor vehicles in the parking lot, and then Tenant shall pay to Landlord that
portion of the tax, fee and/or excise based on Tenant's right to non-exclusive
parking of One Hundred Eighty Two (182) parking spaces, consisting of
approximately 50 percent of the Project parking lot capacity.

     7.9 ALTERATIONS:

         (a) Tenant shall not make any alterations, improvements, repairs,
additions, installations, or changes of any nature in or to the Premises
(individually and collectively, "Alterations") without Landlord's prior written
consent, which consent shall not be unreasonably withheld or delayed more than
ten (10) days after Landlord's receipt of Tenant's request for Landlord's
consent. If written consent is obtained from Landlord, any construction
undertaken by Tenant in or to the Premises shall comply with all the terms and
provisions of Sections 7.9(b) and 7.9(c). All Alterations made by Tenant shall
become the property of Landlord and a part of the realty and shall be
surrendered to Landlord upon the Expiration Date, Option Expiration Date or
sooner termination of the Lease, or, at Landlord's election but only in the
event that Landlord's approval of any such Alteration prior to installation
specified that such Alteration would be removed upon termination, and shall be
removed before the last day of the Term after receiving ninety (90) days prior
written notice from Landlord to Tenant or thirty (30) days after notice of
Landlord's election is given to Tenant in the event of earlier termination of
the Lease. All damage caused by such removal shall be repaired with all due
diligence by Tenant at its sole cost and expense.

         (b) Tenant must utilize only bondable licensed contractors for any
Alterations proposed to be made in or to the Premises. Tenant shall promptly
provide Landlord with copies of bid solicitations and bids received for all such

         (c) Alterations whether installed by Tenant or Tenant's Representatives
at any time prior to or during the Term shall be completed only in compliance
with the following:

              (i) Except as to Alterations which are reasonably expected to cost
less than Twenty Thousand Dollars ($20,000.00), no work shall commence without
(A) Landlord's prior written approval or written waiver of right to approve
Tenant's contractor, (B) certificates of insurance acceptable to Landlord from a
company or companies approved by Landlord, furnished to Landlord by Tenant's

request for approval, and (D) with respect to any work estimated to cost more
the $50,000.00, procurement by Tenant or its contractor, if required by
Landlord, of both a performance and labor and materials payment bond (or a
single bond including such coverage) guaranteeing lien-free completion of the
work of improvements.

              (ii) Notwithstanding Section 7.9(c)(i), all work on any
Alterations shall be performed in conformity with a valid permit and all other
applicable permits or licenses when and where required by cognizant government
authority or agency, copies of which shall be furnished to Landlord before the
work is commenced, and any work not acceptable to any governmental authority or
agency having or exercising jurisdiction over such work, or not reasonably
satisfactory to Landlord, shall be promptly corrected at Tenant's sole cost and
expense. Notwithstanding any failure by Landlord to object to any such work,
Landlord shall have no responsibility thereof either to Tenant or to third
parties.

              (iii) Notwithstanding Section 7.9(c)(i), all work or any
Alterations shall be performed at such time and in such manner as Landlord may

written approval, any extraordinary costs incurred for monitoring any
substantial changes to the Premises.

              (iv) Tenant shall reimburse Landlord subject to Tenant's prior
written approval, for any extraordinary expense actually incurred by Landlord by
reason of faulty work performed by Tenant or its contractors, or by reason of
delays caused by such work, or by reason of inadequate cleanup.

              (v) Tenant or its contractors will in no event be allowed to
install plumbing, mechanical equipment, electrical wiring or fixtures,
acoustical or integrated ceilings, or partitions, unless such installation is
consistent with plans and specifications previously approved in writing by

electrical contractor. Tenant assumes the risk of all damage, costs, and expense
which is incurred by Landlord or other Premises tenants as the result of
Tenant's installation of electrical equipment in the Premises without the
supervision of Landlord or its electrical contractor. Tenant shall pay any
additional costs on account of any increased support to the floor load necessary

construction done or caused to be done by it on the Premises. Tenant shall keep
the Premises free and clear of all mechanics' liens resulting from such
Alterations or other construction. Tenant shall have the right to contest the
correctness or validity of any such lien if, immediately on demand by Landlord,
Tenant procures and records a lien release bond, issued by a corporation
satisfactory to Landlord and authorized to issue surety bonds in California, in
an amount equal to one hundred fifty percent (150%) of the amount of the claim
of lien. The bond shall meet the requirements of California Civil Code Section
3143, shall indemnify Landlord against liability for such claim of lien and
shall hold the Project free from the effect of such claim of lien. In addition,
Landlord may require Tenant to pay Landlord's reasonable and necessary
attorneys' fees and costs in participating in such an action.

     7.11 INDEMNITY AND EXEMPTION OF LANDLORD FROM LIABILITY:

         (a) Except to the extent caused by the negligence or willful misconduct
of Landlord or Landlord's Representatives, Tenant shall indemnify, protect and
defend Landlord against all claims arising from (i) the use of the Premises by
Tenant, Tenant's Representatives and/or Tenant's Invitees, (ii) the conduct of
Tenant's business, (iii) any activity, work or things done, permitted or
suffered by Tenant or any of Tenant's Representatives in or about the Premises
or elsewhere, (iv) any breach or default in the performance of any obligation to
be performed by Tenant under this Lease, or (v) any negligence of Tenant,
Tenant's Representatives and/or Tenant's Invitees, and against all costs,
attorneys' fees, expenses and liabilities incurred in the defense of any such
claim and any action or proceeding brought on such claim. If any action or
proceeding is brought against Landlord by reason of any such claim, Tenant upon
written notice from Landlord shall defend such action or proceeding at Tenant's
sole cost by counsel satisfactory to Landlord. Tenant assumes all risk of damage
to property and injury to persons in, upon or about the Premises arising from
any cause, and Tenant waives all claims against Landlord in respect of such
damage or injury, except to the extent caused by Landlord's or Landlord's
Representative's sole and exclusive gross negligent acts or willful misconduct.
Tenant's obligations pursuant to this Section 7.11 shall survive the termination
of this Lease.

         (b) Landlord shall not be liable for injury to Tenant's business or any
loss of income from such business or for damage or injury to the goods, wares,
merchandise, or other property or the person of Tenant, Tenant's Representatives
or Tenant's Invitees or any other persons in, upon or about the Premises,
whether such damage, loss or injury is caused by or results from criminal acts,
fire steam, electricity, gas, water or rain, or from the breakage, leakage,
obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing,
air conditioning or lighting fixtures, or from any other cause, whether such
damage, loss or injury results from conditions arising upon the Premises or from
other sources or places and regardless of whether the cause of such damage, loss
or injury or the means of repairing such damages, loss or injury is inaccessible
to Tenant.

     7.12 PREMISES CHANGES: This Lease shall not be affected or impaired by any
change to any part of the Project or any sidewalks, streets or improvements
nearby the Project, provided that access to the Premises, parking for the

     7.13 SERVICES AND UTILITIES:

         (a)  Tri-Water System:

              (i) Landlord has installed that portion of the water source heat
pump system set forth in the first and second paragraphs of Weather Engineering
letter to Roel Construction Company dated April 6, 1993 attached as Exhibit "F"
and Landlord agrees to install a second circulating pump to operate alternately
with the existing pump and flush out all existing piping. The complete water
source heat pump system is described in Exhibit "F" ("Tri Water System").

              (ii) The parties agree that the adequacy of the existing Tri-Water
System cannot be determined until the Final Space Plan (as defined in the Work
Letter) has been approved. If the Tri-Water System does not comply with Tenant's
specifications as reasonably determined by Tenant's consultant(s), then Landlord
shall pay a sum not to exceed Twenty Thousand Dollars ($20,000) to improve the
Tri-Water System, or to install an auxiliary system to the Tri-Water System. The
method chosen to comply with Tenant's specifications, if necessary, shall be
determined by Tenant and approved by Landlord, which approval shall not be
unreasonably withheld. Tenant shall pay all costs in excess of $20,000 in the
event the improvement of the Tri-Water System or installation of an auxiliary
system to the Tri-Water System costs more than Twenty Thousand Dollars
($20,000). The improved or auxiliary system shall become a part of the Building
for all purposes except as specifically set forth in this Section 7.13.

              (iii) Tenant shall install as a component of the Work all portions
of the Tri-Water System within the Building which is set forth generally as
items 1 through 9 in Exhibit "F" and in that certain letter dated April 29, 1993
from Walsh Engineers (Exhibit "F1"). Tenant shall install as a component of Work
the improvement to the Tri-Water System or an auxiliary system if necessary.
Tenant shall obtain a twelve (12) month warranty on that portion of the
Tri-Water System or auxiliary system installed by Tenant. The warranty shall
provide that except for routine scheduled maintenance, all other maintenance and
repair work shall be at no cost to Landlord. The cost of the warranty, if any,
shall be at Tenant's expense. Tenant shall provide Landlord a copy of the
warranty upon Substantial Completion. Tenant shall install at Tenant's cost a
monitoring device to measure off-hours use of the Tri-Water System. Tenant shall
pay all costs of the Tri-Water System including any improvement or an auxiliary
system except as installed by Landlord as set forth in Section 7.13(a). Tenant
shall bear the financial responsibility of wear and tear on the Tri-Water System
by reason of use of such system during off-hours periods (other than 7:00 a.m.
to 7:00 p.m. Monday through Friday and 8:00 a.m. to 2:00 p.m. on Saturday) by
payment to Landlord, on a monthly basis, of the sum of One Dollar and Fifty
Cents ($1.50) per hour for each hour (or portion thereof) of off-hours use of
the Tri-Water System. Tenant shall provide Landlord written documentation to
support the off-hour use which shall accompany the monthly payment.

         (b) Landlord's Responsibility: Landlord shall provide to the Building
telephone service and electrical service to the utilities equipment room in the
Builiding. Landlord shall install water line(s) to the Building at Landlord's
expense. Landlord shall furnish elevator service consisting of non-attended
automatic elevators, lighting replacement for exterior standard lights, daily
janitor services, and such other services and pursuant to the specifications set
forth on attached Exhibit "F". If Tenant uses heat generating machines or
equipment in the Premises which affect the temperature otherwise maintained

<PAGE>   23



by the Tri-Water System for the Premises, Landlord reserves the right to install
supplementary air conditioning units in the Premises and the cost thereof,
including the cost of installation, operation and maintenance thereof, shall be
paid by Tenant to Landlord upon written demand by Landlord.

         (c) Interruption of Services: In the event of any interruption of
service required to be provided by Landlord hereunder where such interruption is
caused by the negligence or willful misconduct of Landlord, Tenant shall be
entitled to abatement of Base Rent and Lease Expenses Difference in proportion
to the reasonable denial of use caused by the interruption, beginning on the
later of the third day after Tenant provides Landlord with notice of the
interruption or the actual date when Tenant stops using all or any affected
portion of the Premises because of the interruption, and continuing until the
restoration of the interrupted service. Notwithstanding the foregoing, Tenant
acknowledges that services to be supplied by Landlord hereunder may be
interrupted because of accidents, repairs, alterations, improvements or other
reasons beyond the reasonable control of Landlord. Except as set forth in the
next sentence of this Section 7.13 (c) no such interruption shall (i) be
considered an eviction or disturbance of Tenant's use and possession of the
Premises; (ii) make Landlord liable to Tenant for damages; (iii) abate Basic
Rent or Lease Expenses Difference or (iv) relieve Tenant from performing its
obligations hereunder. Notwithstanding the preceding sentence, if any essential
services (such as the Tri-Water System, passenger elevators, electricity or
water) supplied by Landlord are interrupted and the interruption does not result
from the negligence or willful misconduct of Landlord or Landlord's
Representatives, Tenant shall be entitled to an abatement of Base Rent and Lease
Expenses Difference beginning on the fourth consecutive business day of the
interruption and continuing until the interrupted services are restored.

         (d) Tenant's Responsibility: As part of the Work, Tenant shall install
separate utility meters for electrical, gas and water service to the Premises
and any monitoring devices required to measure off-hours use of the Tri-Water
System. Tenant shall be responsible for the payment for all electrical, gas and
water service to the Premises and the Tri-Water System during the Term.

         (e) Excessive Consumption: Tenant shall not connect any apparatus with
electric current except through existing electrical outlets in the Premises,
without Landlord's prior written consent which shall not be unreasonably
withheld. Tenant shall not consume water in excess of that usually and
reasonably furnished or supplied for the use of other tenants in the Project
using their premises as general office space, including limited lunchroom
facilities (as reasonably determined by Landlord), without first procuring the
written consent of Landlord, which will not be unreasonably withheld provided
that Tenant shall be responsible to pay for such excess use, and in the event of
consent, Landlord may cause to be installed a water meter for the Premises to
measure the amount of water consumed. The cost of any such meter and of its
installation, maintenance and repair shall be paid for by the Tenant and Tenant
agrees to pay Landlord promptly upon demand for all such water consumed as shown
by said meter, at the rates charged for such services by the local public
utility company plus any additional reasonable and necessary expense incurred by
Landlord in keeping account of the water so consumed. If a separate meter is not
installed, the excess cost for such water shall be established by an estimate
made by a utility company hired by Landlord at Tenant's expense.

     7.14 RULES: Tenant and Tenant's Representatives shall observe faithfully
and comply strictly with the rules and regulations that are set forth in
attached Exhibit "E" and such other rules as Landlord may from time to time
reasonably adopt and disclose to Tenant for the Real Property and the Project
("Rules").

     7.15 MAINTENANCE OBLIGATIONS:

         (a) Tenant at its sole cost shall maintain (except to the extent
janitorial services are supplied by Landlord as set forth in the janitorial
specifications in Exhibit "J"), and repair, all in neat, clean, broom-clean and
good condition, with allowances for reasonable wear and tear ("Good Condition"),
all portions of the Premises, except those portions of the Premises to be
maintained by Landlord as expressly described in Section 7.15(b). Tenant shall
be liable for any damage to the Project resulting from the acts or omissions of
Tenant or Tenant's Representatives. If Tenant fails to maintain the Premises as
provided above, then after applicable periods of notice and periods to cure as
set forth in Section 12.1(b), Landlord shall have the right but not the
obligation to maintain the Premises and Tenant shall promptly reimburse Landlord
for Landlord's actual cost of such maintenance.



<PAGE>   24



         (b) Subject to Section 7.15(a), Landlord shall maintain, repair,
replace and repaint (i) the structural parts of the Building, which are limited
to foundations, bearing and exterior walls (excluding glass doors which are part
of Tenant's Premises), subflooring, and roof; (ii) the unexposed electrical,
plumbing, sewage systems and mechanical systems, elevators and elevator shafts
which are not part of the Work; (iii) windows and window frames, gutters and
downspouts on the Building; (iv) the Tri-Water System and any auxiliary system
to the Tri-Water System, if any, for the Building; and (v) that portion of the
Building not included as part of the Premises and the Common Area.

         (c) Landlord's failure to perform its obligations set forth in Section
7.15(b) shall not release Tenant of its obligations under this Lease, including
without limitation Tenant's obligation to pay Rent. Tenant waives the provisions
of California Civil Code Sections 1941 and 1942 with respect to Landlord's
obligations for tenantability of the Premises and Tenant's right to make repairs
and deduct the expenses of such repairs from rent.

     7.16 BUILDING SECURITY: Landlord shall supply building security systems and
services as set forth in Exhibit "G" and Exhibit "G1" or the equivalent as
reasonably determined by Landlord. Except for the service to be provided as set
forth in Exhibits "G" and "G1", Tenant acknowledges (a) that the monthly Base
Rent does not include the cost of additional security measures for any portion
of the Project, (b) that Landlord shall have no obligation to provide any such
additional security measures, and (c) that Landlord has made no representation
to Tenant regarding the safety or security of the Project. Tenant assumes all
responsibility for the security and safety of Tenant and/or Tenant's Invitees
and Tenant's employees. Except to the extent caused by the negligence or
intentional misconduct of Landlord or Landlord's Representatives, Tenant
releases Landlord from all claims for damage, loss or injury to Tenant, Tenant's
Invitees, Tenant's employees and/or to Tenant's Personal Property, even if such
damage, loss or injury is caused by or results from the criminal or negligent
acts of third parties. Landlord shall have no duty to warn Tenant of any
criminal acts or dangerous conduct that has occurred in or near the Premises,
unless Landlord has received written notice of such acts or conduct.

     7.17 TENANT TO PAY PERSONAL PROPERTY TAXES: Tenant shall pay before
delinquent all taxes, assessments, license fees, and other charges levied or
assessed against, or based upon the value of Tenant's Personal Property
("Personal Property Taxes") that become payable during the Term. On written
demand by Landlord, Tenant shall furnish Landlord with written satisfactory
evidence of such payments. If any Personal Property Taxes are levied against
Landlord or Landlord's property, or if the assessed value of the Project is
increased by the inclusion of a value placed on Tenant's Personal Property, and
if Landlord pays such Personal Property Taxes or any taxes based on the
increased assessments caused by such Tenant's Personal Property, then Tenant, on
demand, shall immediately reimburse Landlord for the sum of the Personal
Property Taxes so levied against Landlord, or the proportion of taxes resulting
from such increase in Landlord's assessment. Landlord shall have the right to
pay such Personal Property Taxes or such proportion, and receive such
reimbursement, regardless of the validity of the levy.

                                    SECTION 8
                                    INSURANCE

     8.1 TENANT'S INSURANCE:

         (a) Public Liability and Property Damage Insurance: Tenant shall
procure at its sole cost and expense and keep in effect from the date of this
Lease at all times until the end of the Term, comprehensive general liability
insurance insuring against liability of Tenant, Tenant's Representatives,
Landlord, and Landlord's Representatives, arising out of or in connection with
Tenant's use or occupancy of the Premises or any part thereof, or the Project by
Tenant or Tenant's Representative. Such insurance shall include contractual
liability insurance coverage insuring Tenant's indemnity obligations under this
Lease. Such coverage shall have a minimum combined single limit of liability of
not less than $1,000,000 with a minimum general aggregate limit of
$1,000,000.00. Such policies shall be written to apply to property damage,
bodily injury, personal injury, premises medical payments, fire legal liability,
general liability and other covered losses, however occasioned, occurring during
the policy term, naming the Landlord and Landlord's lender as additional
insureds, providing that such coverage shall be primary and that any insurance
maintained by Landlord shall be excess insurance only. Such coverage shall also
(i) delete any employee exclusion on personal injury coverage; (ii) include
employees as insureds; (iii) include liquor liability and (iv) include
employer's automobile non-ownership liability. All such insurance shall provide
for severability of interests or contain a cross-liability endorsement and shall
provide that an act or omission of one of the named


<PAGE>   25


insureds shall not reduce or avoid coverage to the other named insureds; and
shall afford coverage for all claims based on acts, omissions, injury and
damage, which claims occurred or arose (or the onset of which occurred or arose)
in whole or in part during the policy period.

         (b) Automobile Liability Insurance: Tenant shall procure at its sole
cost and expense and keep in effect from the date of this Lease at all times
until the end of the Term, if applicable, Comprehensive Automobile Liability
insurance covering owned, non-owned and hired vehicles. Such coverage shall have
a minimum combined single limit of liability of not less than $1,000,000.

         (c) Workers Compensation Insurance: Tenant shall, if applicable,
maintain Workers' Compensation insurance in accordance with California law, and
employer's liability insurance with a limit of not less than $1,000,000.
Workers' Compensation insurance shall be endorsed to waive the insurer's right
of subrogation against Landlord.

         (d) Business Personal Property and Loss of Income Insurance: Tenant
shall, if applicable, maintain business personal property insurance to pay for
damage to or destruction of the Tenant's property from damage to or destruction
of the Premises. Such insurance shall insure against losses on an "all-risk"
type policy to the extent of at least one hundred percent (100%) of the full
replacement value of business personal property.

         (e) Maintaining Insurance: If Tenant fails during the Term to maintain
any insurance required to be maintained by Tenant under this Lease, then
Landlord may, at its option and in addition to Landlord's other remedies in the
event of default by Tenant, arrange for any such insurance, and Tenant shall
reimburse Landlord for any premiums for any such insurance within five (5)
business days after Tenant receives a copy of the premium notice. If such
premiums are allocable to a period, a portion of which occurs during the Term
and the remainder of which occurs before or after the Term, then such premiums
shall be apportioned between Landlord and Tenant based upon the number of days
during such period that occurred during the Term and the number of days that
occurred before or after the Term, such that Tenant pays for the premiums that
are allocable to the period during the Term. Insurance required to be maintained
by Tenant under this Lease (i) shall be issued as a primary policy by insurance
companies authorized to do business in the State of California with a Best's
rating of a least "A" and a Best's financial size category rating of at least
"VIII", as set forth in the most current edition of Best's insurance reports or
such higher rating as may be required by Landlord's lender, (ii) shall name the
Additional Insureds as additional named insureds, (iii) shall constitute
"occurrence" based coverage, without provision for subsequent conversion to
"claims" based coverage, and (iv) shall not be cancelable or subject to
reduction of coverage or other modification except after thirty (30) days' prior
written notice to Landlord and any lender. Tenant shall, at least thirty (30)
days prior to the expiration of any such policy, furnish Landlord with a renewal
or binder of such policy. Tenant shall, upon request from Landlord, promptly
deliver to Landlord copies of such policy or policies or certificates evidencing
the existence and amounts of such insurance together with evidence of payment of
premiums. Any policy required to be maintained by Landlord or Tenant under this
Lease may be maintained under a so-called "blanket policy" insuring other
parties and/or other locations, so long as the amount of insurance and type of
coverage required to be provided under this Lease is not thereby diminished,
changed or adversely affected.

         (f) All insurance coverage, terms and conditions described in this
Section 8.1 shall be evidenced by a Certificate of Insurance issued to Landlord.
A copy of all insurance policies issued to Tenant during the Term shall be
forwarded to Landlord within sixty (60) days after the Commencement Date.

         (g) If at any time during the Term the amount or coverage of insurance
which Tenant is required to carry under this Section 8.1 is, in Landlord's
reasonable judgment, materially less than that amount or type of insurance
coverage typically carried by owners or tenants of properties located in San
Diego, California, which are similar in size and used for similar purposes as
the Premises, Landlord shall have the right to require Tenant to increase the
amount or change the types of insurance coverage required under this Section
8.1.

     8.2 Landlord's Insurance: Landlord shall, at its expense, maintain in
effect at all times during the Term: a policy or policies of "all risk" fire,
general liability and extended coverage insurance, including at least six (6)
months rental interruption insurance, with vandalism and malicious mischief
endorsements, coverage with respect to increased costs due to building
ordinances, demolition coverage, boiler and machinery insurance, sprinkler
leakage coverage, in each case to the extent of at least one hundred


<PAGE>   26



percent (100%) of the full replacement value of the Building and Adjacent
Building and any future building on the Project. Landlord shall notify Tenant of
Landlord's obtaining any such insurance. If Landlord fails during the Term to
maintain any insurance required to be maintained by Landlord under this Lease,
then Tenant may, at its election, arrange for any such insurance, and Tenant may
require that Landlord reimburse Tenant for any premiums for any such insurance
within five (5) days after Landlord or Tenant's receipt of the premium notice.
Insurance required to be maintained by Landlord under this Lease (a) shall be
issued as a primary policy by insurance companies authorized to do business in
California with a Best's Rating of at least "A" and a Best's Financial Size
Category rating of at least "VIII," as set forth in the most current edition of
"Best's Insurance Reports," or such higher rating as may be required by any
lender, (b) shall name Tenant and any lender or other party as Tenant may elect
as additional named insureds, (c) shall constitute "occurrence" based coverage,
without provision for subsequent conversion to "claims" based coverage, and (d)
shall not be cancelable or subject to reduction of coverage or other
modification except after thirty (30) days' prior written notice to Tenant and
any lender. Landlord shall, at least thirty (30) days prior to the expiration of
each such policy, furnish Tenant with a renewal or "binder" of such policy.
Landlord shall, upon request from Tenant, promptly deliver to Tenant copies of
such policy or policies or certificates evidencing the existence and amounts of
such insurance together with evidence of payment of premiums. The premiums,
costs and expenses and deductibles of and/or with respect to any such insurance
shall be included in the Building Operating Expenses. Landlord shall not
increase the amount or types of insurance coverage beyond that which was in
place during the Base Year, other than reasonable increases to reflect inflation
or an increase in value of the insured property. Landlord has set forth on
Exhibit "O" quotes for any insurance coverage Landlord may reasonably obtain in
the future. If Landlord subsequently obtains in any Lease Year insurance
coverage which is set forth on Exhibit "O", then Lease Expenses for the Base
Year shall include the insurance quotes on Exhibit "O" and Lease Expenses for
the Lease Year shall include the cost of insurance to the extent increases over
the quotes are a result of reasonable increases for inflation or the value of
the insured property.

                                    SECTION 9
                                   DESTRUCTION

     9.1 RISK COVERED BY INSURANCE:

         (a) If during the Term the Premises is totally or partially destroyed,
rendering the Premises totally or partially inaccessible or unusable, Landlord
shall, subject to Sections 9.1(b) and 9.1(c), restore the Premises to
substantially the same condition as it was in immediately before the
destruction. Such destruction shall not terminate this Lease. If, however,
then-existing laws do not permit such restoration, Landlord may terminate this
Lease by giving written notice to Tenant.

         (b) If Landlord determines that the cost of such restoration exceeds
the amount of proceeds received by Landlord from any insurance maintained by
Landlord, then Landlord may elect to terminate this Lease by giving notice to
Tenant within sixty (60) days after such destruction or within sixty (60) days
after Landlord's receipt of such proceeds, whichever is later. If Landlord gives
such notice of termination, then this Lease shall terminate as of forty-five
(45) days after Landlord's notice of termination, unless Tenant provides
Landlord with written notice of its election to pay the amount by which the cost
of such restoration exceeds the amount of proceeds received by Landlord ("Notice
To Restore"), in which event this Lease shall remain in full force and effect.
Tenant shall have thirty (30) days after Notice To Restore to pay the excess
cost of restoration either to Landlord or to an escrow account to be used for
restoration.

         (c) Within thirty (30) days after such destruction, Landlord shall
notify Tenant in writing whether or not, based on Landlord's determination, the
Premises can be restored within six (6) months after the date of such
destruction. If such restoration cannot be completed within such six (6) month
period, either party may terminate this Lease by giving written notice to the
other party within twenty (20) days after the date of Landlord's written notice.
If Landlord determines that the Premises can be restored within such six (6)
month period and neither party terminates this Lease pursuant to this Section 9,
Landlord shall use its reasonable efforts to restore the Premises within such
six (6) month period to substantially the same condition as it was in
immediately before the destruction.

     9.2 ABATEMENT OR REDUCTION OF RENT: In case of any destruction to the
Premises, all obligations of Tenant under this Lease shall remain in effect,
except that Base Rent and Lease Expenses Difference shall be abated or reduced,
between the date of such destruction and the date of completion of restoration,
by



<PAGE>   27


the ratio of (a) the area of the Premises rendered unusable or inaccessible by
the destruction to (b) the area of the Premises prior to such destruction.

     9.3 LOSS DURING LAST PART OF TERM OR EXCEEDING TWENTY-FIVE PERCENT (25%) OF
REPLACEMENT VALUE: Not withstanding any other provision of this Lease, if any
destruction to the Premises occurs during the last year of the Term, or if, at
any time during the Term, there is any destruction to the Premises that exceeds
twenty-five percent (25%) of the then replacement value of the Premises,
Landlord or Tenant may terminate this Lease by giving written notice to the
other not more than thirty (30) days after such destruction, in which case (a)
neither Landlord nor Tenant shall have any obligation to restore the Premises,
(b) Landlord shall retain all insurance proceeds relating to such destruction
except for insurance proceeds relating to the loss of or damage to Tenant's
Personal Property or loss of business, and (c) this Lease shall terminate as of
thirty (30) days after such notice of termination.

     9.4 LIMITATION ON LANDLORD'S RESTORATION OBLIGATION: If Landlord is
required or elects to restore the Premises as provided in Section 9.1, Landlord
shall not be required to restore any of Tenant's Alterations which were
constructed without Landlord's written consent or any of Tenant's Personal
Property, unless they are an integral part of the Premises and specifically
covered by insurance proceeds received by Landlord, such excluded items being
the sole responsibility of Tenant to restore.

                                   SECTION 10
                                  CONDEMNATION

     10.1 DEFINITIONS: For purposes of this Lease, the following definitions
shall apply:

         (a) "Condemnation" shall mean the exercise of any governmental power,
whether by legal proceedings or otherwise, by a Condemnor (as defined below) or
a voluntary sale or transfer by Landlord to any Condemnor, either under threat
of condemnation or while legal proceedings for condemnation are pending;

         (b) "Date of Taking" shall mean the date the Condemnor has a right to
possession of the property being condemned;

         (c) "Award" shall mean all compensation, sums or anything of value
awarded, paid, or received on a total or partial Condemnation of the Project;
and

         (d) "Condemnor" shall mean any public or quasi-public authority, or
private corporation or individual, having the power of Condemnation.

     10.2 GOVERNED BY LEASE: If during the Term, or during the period of time
between the execution of this Lease and the Commencement Date, there is any
taking of all or any part of the Project or any interest in this Lease by
Condemnation, the rights and obligations of Landlord and Tenant shall be
determined pursuant to this Section 10.

     10.3 TOTAL TAKING: If the Premises are totally taken or more than thirty
percent (30%) of the available parking area is taken by Condemnation, this Lease
shall terminate on the Date of Taking.

     10.4 PARTIAL TAKING: If any portion, but not all, of the Premises is taken
by Condemnation, this Lease shall remain in effect, except that Tenant may elect
to terminate this Lease if the remaining portion of the Premises is rendered
unsuitable for Tenant's continued use of the Premises. If Tenant elects to so
terminate this Lease, Tenant must exercise its right to terminate by giving
notice to Landlord within sixty (60) days after the date that the nature and the
extent of the taking have been determined ("Determination Date"), which notice
shall set forth the date of termination. Such termination date shall not be
earlier than thirty (30) days nor later than ninety (90) days after Tenant has
notified Landlord of its election to terminate; except that this Lease shall
terminate on the Date of Taking if the Date of Taking falls on a date before the
date of termination as designated by Tenant. If Tenant does not so notify
Landlord within sixty (60) days after the Determination Date, all obligations of
Tenant under this Lease shall remain in effect, except that Base Rent shall be
reduced by the ratio of (a) the area of the Premises taken to (b) the area of
the Premises immediately prior to the Date of Taking.

<PAGE>   28



     10.5 AWARD: The Award shall belong to and be paid to Landlord, Tenant shall
have no right to any part of the Award, and Tenant assigns to Landlord all of
Tenant's right, title and interest in and to any part of the Award, except that
Tenant shall receive from the Award an amount equal to the value of Tenant's
leasehold interest and any sum paid expressly to Tenant from the Condemnor for
relocation, the cost of tenant improvements which were paid for by Tenant and
not part of the Tenant Improvement Allowance, the value of Alterations and loss
of goodwill.

     10.6 TEMPORARY TAKING: The taking of the Premises or any part of the
Premises by military or other public authorities shall constitute a taking of
the Premises by Condemnation only when the use and occupancy by the taking
authority is continued for longer than one hundred eighty (180) consecutive
days. During the one hundred eighty (180) day period, all obligations of Tenant
under this Lease shall remain in effect, except that Base Rent shall be abated
or reduced during such period of taking by the ratio of (a) the area of the
Premises taken to (b) the area of the Premises immediately prior to the Date of
Taking, and Landlord shall be entitled to any Award related to such taking.

     10.7 WAIVER OF STATUTE: Landlord and Tenant waive the provision of
California Code of Civil Procedure Section 1265.130 allowing Landlord or Tenant
to petition the superior court to terminate this Lease in the event of a partial
taking of the Premises.

                                   SECTION 11
                            ASSIGNMENT AND SUBLETTING

     11.1 ASSIGNMENT:

         (a) Tenant shall not assign, enter into a license or concession
agreement for, hypothecate or otherwise divest itself of this Lease or any of
its rights under this Lease or permit any third party or parties other than
Tenant to occupy the Premises or any portion thereof without Landlord's prior
written consent, which consent shall not be unreasonably withheld, but is
subject to the terms and conditions contained in this Section 11.

         (b) For purposes of this Lease, each of the following events shall be
deemed to constitute an assignment of this Lease:

              (i) any assignment or transfer of this Lease, or any interest in
this Lease, voluntarily, involuntarily, by operation of law or otherwise;

              (ii) any mortgage, hypothecation, pledge, or collateral assignment
of this Lease or any interest in this Lease;

              (iii) any sale, transfer, grant of concessions or licenses, or
other disposition of this Lease, any interest in this Lease or all or any
portion of the Premises;

              (iv) any assignment, transfer, disposition, sale, or acquisition
of a controlling interest in Tenant to or by any person, entity, or group of
related persons or affiliated entities, whether in a single transaction or in a
series of related or unrelated transactions ("Change of Control"). For purposes
of this Lease a "Change of Control" shall mean a change in the identity of the
person or persons exercising, or who may exercise, effective control of Tenant,
unless such change results from either (A) the acquisition of Tenant by a
publicly traded company, (B) the trading of shares listed on a recognized
national securities exchange, or (C) the transfer of interests in Tenant for
purposes of estate or tax planning; and


<PAGE>   29




              (v) any issuance of an interest or interests in Tenant (whether
stock, partnership interests, or otherwise) to any person, entity, or group of
related persons or affiliated entities, whether in a single transaction or in a
series of related or unrelated transactions, which results in Change of Control.

         (c) At least fifteen (15) days prior to entering into any assignment of
this Lease of all or any portion of the Premises, Tenant shall submit to
Landlord the form of such proposed assignment, and a written notice ("Tenant's
Notice") setting forth in reasonable detail (i) the name and address of the
proposed assignee, (ii) the terms and conditions of the proposed assignment,
including without limitation the proposed effective date of the assignment,
which shall be at least thirty (30) days after Tenant's Notice is given, (iii)
the nature and character of the business of the proposed assignee, and (iv)
current banking, financial, and other credit information, including prior year's
federal tax return, if available, (all of which information Landlord agrees to
treat as strictly confidential and not disclose or disseminate to third parties)
relating to the proposed assignee, in reasonably sufficient detail, to enable
Landlord to determine the proposed assignee's financial responsibility.

         (d) Within thirty (30) days after Landlord's receipt of Tenant's Notice
and the form of assignment, Landlord shall notify Tenant whether Landlord has
consented to the proposed assignment. Any consent granted by Landlord in any
instance shall not constitute a consent with respect to any other instance or
request. If Landlord consents to any proposed assignment and Tenant fails to
consummate such assignment within one hundred eighty (180) days after such
consent, then such consent shall be deemed withdrawn and Tenant shall be
required again to comply with this Section 11 before assigning this Lease or any
portion of the Premises.

         (e) Landlord shall not have unreasonably withheld its consent with
respect to any assignment if Landlord shall not have received Tenant's Notice as
provided above, nor if (i) the nature and character of the proposed assignee and
the proposed use and occupancy of the Premises by the proposed assignee is not
in keeping with the dignity and character of the Premises and the surrounding
area, (ii) the proposed assignment will result in the diminution of the value or
marketability of the Premises, (iii) upon review of the information furnished in
Tenant's Notice, Landlord is not satisfied that the proposed assignee's use of
the Premises will not conflict with other uses in the Premises. Tenant
acknowledges that Tenant's Notice shall be ineffective if Tenant is in material
default with respect to any provision under this Lease.

     11.2 SUBLEASE: If Tenant is not in default of the Lease, Tenant may
sublease all or a portion of the Premises upon Landlord's prior written consent,
which consent shall not be unreasonably withheld. Any sublease of all or a
portion of the Premises shall be in accordance with the terms and conditions of
this Section 11 and all other applicable terms and conditions of this Lease.
Tenant's request to sublease all or a portion of the Premises shall be in the
form of the Tenant's Notice as set forth in Section 11.1(c).

         (a) Any sublease of all or any portion of the Premises must contain the
following provisions, which provisions, whether contained in such sublease nor
not, shall apply to such sublessee:

              (i) Such sublease shall be subject and subordinate to all of the
provisions of this Lease (including all exhibits) and any subsequent amendments
of this Lease;

              (ii) At Landlord's option, in the event of cancellation or
termination of this Lease for any reason or the surrender of this Lease, whether
voluntarily, involuntarily, or by operation of law, prior to the expiration of
such sublease, the subtenant shall make full and complete attornment to Landlord
for the balance of the term of such sublease, provided that Landlord agrees in
writing not to disturb subtenant's right to occupy the subleased area as long as
such sublessee is in compliance with its obligations under such sublease. The
subtenant shall execute and deliver to Landlord an agreement of attornment
satisfactory to Landlord within five (5) days after requested by Landlord; and

              (iii) No sublessee shall be permitted to further sublet all or any
portion of the subleased space without Landlord's prior written consent.


<PAGE>   30



         (b) Tenant shall submit all subleases to Landlord prior to execution
for Landlord's review and approval, which shall not be unreasonably withheld or
delayed more than fourteen (14) days after Landlord's receipt of any sublease.

     11.3 TENANT AND ASSIGNEE OR SUBLESSEE FULLY LIABLE: No assignment of this
Lease nor any sublease of all or any portion of the Premises shall release or
discharge Tenant from any liability, whether past, present, or future, under
this Lease and Tenant shall continue to remain primarily liable under this
Lease. The assignee of any assignment of this Lease, and the sublessee of any
sublease of all or any portion of the Premises, shall execute, acknowledge, and
deliver to Landlord an agreement satisfactory to Landlord in which the assignee
or sublessee assumes and agrees to be bound by all of the provisions of this
Lease.

     11.4 ASSIGNMENT OF RENTS: Tenant irrevocably assigns to Landlord, as
security for Tenant's obligations under this Lease, all rent from any subletting
of all or any portion of the Premises, and Landlord, as assignee and as special
attorney-in-fact for Tenant, or a receiver for Tenant appointed on Landlord's
application, may collect such rent and apply it toward Tenant's obligations
under this Lease, except that, unless Tenant defaults under this Lease, Tenant
shall have the right to collect such rent.

     11.5 SUBLEASE ASSIGNMENT RIGHT: Landlord and Tenant shall share equally any
"Premium" (as defined below) arising from the sublease of any portion of the
Premises to any entity which is not a subsidiary of Tenant. For purposes of this
paragraph "Premium" shall mean all sums received by Tenant under the sublease
which exceeds the Rent attributable to the subleased portion of the Premises,
after deducting (a) all reasonable expenses of Tenant incurred in connection
with such sublease amortized on a straight line basis over the initial term of
the sublease, including without limitation legal costs, brokerage commissions,
rent abatement and other concessions, lease takeover, subtenant improvement
costs, the unamortized value of Tenant's leasehold improvements, downtime, and
cash payments, (b) any utility costs paid by Tenant which is attributable to
such subleased premises, and (c) any Additional Rent paid by Tenant which is
attributable to such subleased premises. The determination of Base Rent
attributable to the subleased portion of the Premises shall be made on the basis
of the ratio of the rentable square footage in the subleased portion to the
Rentable Square Footage.

                                   SECTION 12
                              DEFAULT AND REMEDIES

     12.1 DEFAULT: The occurrence of any of the following shall constitute a
material default and breach of this Lease by Tenant:

         (a) the failure by Tenant to pay Rent as and when due, where such
failure shall continue for a period of three (3) business days after written
notice of such failure from Landlord to Tenant. In the event that Landlord
serves Tenant with a Notice to Pay Rent or Quit pursuant to applicable statutes
set forth in California Code of Civil Procedure, such Notice to Pay Rent or Quit
shall also constitute the notice of such failure;

         (b) the failure by Tenant to observe or perform any of the provisions
of this Lease to be observed or performed by Tenant, other than described in
Section 12.1(a), where such failure shall continue for a period of thirty (30)
days after written notice of such failure from Landlord to Tenant; provided,
however, that if the nature of Tenant's default is such that more than thirty
(30) days are required for its cure, then Tenant shall not be deemed to be in
default if Tenant commenced such cure within such thirty (30) day period and
thereafter diligently prosecutes such cure to completion within sixty (60) days
after Landlord's written notice; or

         (c) the making by Tenant of any general arrangement or assignment for
the benefit of creditors; Tenant's becoming bankrupt, insolvent or a "debtor" as
defined in 11 U.S.C. Section 101, or any successor statute (unless, in the case
of a petition filed against Tenant, such petition is dismissed within sixty (60)
days after its original filing); the institution of proceedings under bankruptcy
or similar laws in which Tenant is the debtor or bankrupt; the appointing of a
trustee or receiver to take possession of substantially all of Tenant's assets
located at the Premises or of Tenant's interest in this Lease (unless possession
is restored to Tenant within sixty (60) days after such taking); or the
attachment, execution of judicial seizure of substantially all of Tenant's
assets located at the Premises or Tenant's interest in this Lease (unless such
attachment,


<PAGE>   31




execution or judicial seizure is discharged within sixty (60) days after such
attachment, execution or judicial seizure).

     12.2 LANDLORD'S REMEDIES: Landlord shall have the following remedies if
Tenant commits a default or breach under this Lease; these remedies are not
exclusive, but are cumulative in addition to any remedies provided elsewhere in
this Lease or now or later allowed by law.

         (a) Continuation of Lease: No act by Landlord (including without
limitation the acts set forth in this Section 12.2(a)) shall terminate Tenant's
right to possession unless Landlord notifies Tenant in writing that Landlord
elects to terminate Tenant's right to possession. As long as Landlord does not
terminate Tenant's right to possession, Landlord may (i) continue this Lease in
effect, (ii) continue to collect rent when due and enforce all the other
provisions of this Lease, (iii) enter the Premises and relet them, or any part
of them, to third parties for Tenant's account, for a period shorter or longer
than the remaining term of this Lease, and (iv) have a receiver appointed to
collect rent and conduct Tenant's business. Tenant shall immediately pay to
Landlord all costs Landlord incurs in such reletting, including, without
limitation, brokers' commissions, attorneys' fees, advertising costs and
expenses of remodeling the Premises of such reletting.

         (b) Rent from Reletting: If Landlord elects to relet all or any portion
of the Premises as permitted by Section 12.2(a), rent that Landlord receives
from such reletting shall be applied to the payment of, in the following order
and priority, (i) any indebtedness due from Tenant to Landlord (other than Base
Rent), (ii) all costs incurred by Landlord in such reletting, including without
limitation any brokers', finders', or leasing agents' commissions, charges or
fees, and (iii) Base Rent due and unpaid under this Lease. After applying such
payments as referred to above, any sum remaining from the rent Landlord receives
from such reletting shall be held by Landlord and applied in payment of future
Base Rent as it becomes due under this Lease. In no event shall Tenant be
entitled to any excess rent received by Landlord.

         (c) Termination of Tenant's Right to Possession: Landlord may terminate
Tenant's right to possession of the Premises at any time, by notifying Tenant in
writing that Landlord elects to terminate Tenant's right to possession. On
termination of this Lease, Landlord has the right to recover from Tenant (i) the
worth at the time of the award of the unpaid Base Rent which had been earned at
the time of such termination, (ii) the worth at the time of the award of the
amount by which the unpaid Base Rent which would have been earned after such
termination until the time of award exceeds the amount of such loss of Base Rent
that Tenant proves could have been reasonably avoided, (iii) the worth at the
time of the award of the amount by which the unpaid Base Rent for the balance of
the Term after the time of award (had there been no such termination) exceeds
the amount of such loss of Base Rent that Tenant proves could be reasonably
avoided, and (iv) any other amount necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease or in the ordinary course of things would be likely to result
therefrom. The "worth at the time of the award" of the amounts referred to in
Sections 12.2(c)(i) and 12.2(c)(ii) is to be computed by allowing interest at a
rate equal to ten percent (10%) per annum, but in no event greater than the
maximum rate permitted by applicable law. The "worth at the time of the award"
of the amount referred to in Section 12.2(c)(iii) is to be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent (1%).

         (d) Landlord's Right to Cure Default: Landlord, at any time after
Tenant commits a default or breach under this Lease, may cure such default or
breach at Tenant's sole cost. If Landlord at any time, by reason of Tenant's
default or breach, pays any sum or does any act that requires the payment of any
sum, such sum shall be due immediately from Tenant to Landlord at the time such
sum is paid, and shall be deemed additional rent under this Lease.

     12.3 INTEREST AND LATE CHARGES: Rent not paid within five (5) days after
its due date shall bear interest from the date due at a rate equal to ten
percent (10%) per annum, but in no event greater than the maximum rate permitted
by applicable law. Late payment by Tenant to Landlord of Rent will cause
Landlord to incur cost not contemplated by this Lease, the exact amount of which
would be impracticable or extremely difficult to fix. Such costs include,
without limitation, processing, collection and accounting charges, and late
charges that may be imposed on Landlord by the terms of any Mortgage covering
the Premises. Therefore, if any Rent is not received by Landlord within three
(3) business days after notice

<PAGE>   32



to the Chief Financial Officer of Tenant of such overdue payment from Landlord
to Tenant, Tenant shall pay to Landlord an additional sum of five percent (5%)
of such overdue amount as a late charge ("Late Charge"). Landlord and Tenant
agree that the Late Charge represents a fair and reasonable estimate of the
costs that Landlord will incur by reason of any late payment by Tenant, and
therefore this Section 12.3 is reasonable under the circumstances existing at
the time this Lease is executed. Acceptance of the Late Charge by Landlord shall
not constitute a waiver of Tenant's default with respect to such overdue amount,
nor prevent Landlord from exercising any of the other rights and remedies
available to Landlord under this Lease.

     12.4 QUARTERLY PAYMENTS: In the event that a Late Charge is payable under
this Lease, whether or not collected, for three (3) consecutive installments of
Rent or in the event Rent is paid more than thirty (30) days late twice due
under this Lease during any twelve (12) month period, then Base Rent, and
Monthly Payment, shall, at Landlord's election by written notice to Tenant,
become due and payable quarterly in advance, rather than monthly, for a period
of six (6) months. If a Late Charge is payable under the Lease, whether or not
collected, for two (2) installments of Rent during the twelve (12) calendar
months following such six (6) month period, then Base Rent and Monthly Payment
shall automatically become due and payable quarterly in advance for a period of
one (1) year. If any payment is not timely paid during such one year period,
then Base Rent and Monthly Payment shall automatically become due and payable
quarterly in advance for the remaining Term of the Lease. All monies paid to
Landlord under this Section 12.4 may be commingled with other monies of Landlord
and shall not bear interest.

     12.5 WAIVER: No delay or omission in the exercise of any right or remedy of
Landlord in the event of any default by Tenant shall impair such right or remedy
or be construed as a waiver. The receipt and acceptance by Landlord of
delinquent Rent shall not constitute a waiver of any default other than the
particular rent payment accepted. Landlord's receipt and acceptance from Tenant,
on any date ("Receipt Date"), of an amount less than rent due on such Receipt
Date, or to become due (pursuant to Section 4 or Section 6) at a later date but
applicable to a period prior to such Receipt Date, shall not release Tenant of
its obligation (a) to pay the full amount of such rent due on such Receipt Date
or (b) to pay when due the full amount of such rent to become due at a later
date but applicable to a period prior to such Receipt Date. No act or conduct of
Landlord, including without limitation, the acceptance of the keys to the
Premises, shall constitute an acceptance by Landlord of the surrender of the
Premises by Tenant before the Expiration Date or Option Expiration Date. Only a
written notice from Landlord to Tenant stating Landlord's election to terminate
Tenant's right to possession of the Premises shall constitute acceptance of the
surrender of the Premises and accomplish a termination of this Lease. Landlord's
consent to or approval of any act by Tenant requiring Landlord's consent or
approval shall not be deemed to waive or render unnecessary Landlord's consent
to or approval of any other or subsequent act by Tenant. Any waiver by Landlord
of any default by Tenant must be in writing and shall not be a waiver of any
other default concerning the same or any other provision of this Lease.

     12.6 NOTICE OF DEFAULT: Landlord shall not be deemed to be in default in
the performance of any obligation required to be performed by Landlord unless
and until it has failed to perform such obligation within thirty (30) days after
Landlord's receipt of written notice from Tenant specifying Landlord's failure
to perform such obligation. However, if the nature of Landlord's obligation is
such that more than thirty (30) days are required for its performance, then
Landlord shall not be deemed to be in default if it shall commence such
performance within such thirty (30) day period and thereafter prosecutes the
same to completion.

                                   SECTION 13
            SUBORDINATION, ATTORNMENT, ESTOPPEL, AND NON-DISTURBANCE

     13.1 SUBORDINATION: This Lease and Tenant's rights under this Lease are
subject and subordinate to any mortgage, loan secured by a deed of trust, or
other written security instrument or agreement affecting the Project that
constitutes security for the payment of a debt or performance of an obligation
(each, a "Mortgage"), and to all renewals, modifications, consolidations,
replacements or extensions thereof, now or hereafter affecting the Premises. The
provisions of this Section 13.1 shall be self-operative, and no further
instrument of subordination shall be required. Within fifteen (15) days after
written notice from Landlord, Tenant shall execute and deliver any instruments
that Landlord, the holder of any Mortgage, or the lessor of any ground or
underlying lease may reasonably request to evidence

<PAGE>   33



such subordination. If Tenant fails to execute and deliver any such
instrument(s) within fifteen (15) days after such notice, Tenant agrees that
Landlord may then send a second notice and irrevocably constitutes and appoints
Landlord as Tenant's special attorney-in-fact to execute and deliver such
instruments on behalf of Tenant ten (10) days after Landlord's second written
notice to Tenant to execute and deliver requested instrument(s) and Tenant fails
to do so. If Landlord executes documents on behalf of Tenant pursuant to the
special power-of-attorney, it shall be deemed that Tenant has not waived any
rights against Landlord solely due to the use of the special power-of-attorney
by Landlord.

     13.2 ATTORNMENT: If the holder of any Mortgage shall hereafter succeed to
the Landlord under this Lease, Tenant shall attorn to and recognize such
successor as the Landlord under this Lease, and shall promptly execute and
deliver any instruments that may be necessary to evidence such attornment. If
Tenant fails to execute and deliver any such instrument(s) within fifteen (15)
days after written notice from Landlord, Tenant agrees that Landlord may then
send a second notice and irrevocably appoints Landlord as Tenant's special
attorney-in-fact to execute and deliver such instruments on behalf of Tenant ten
(10) days after Landlord's second written notice to Tenant to execute and
deliver requested instrument(s) and Tenant fails to do so. If Landlord executes
documents on behalf of Tenant pursuant to the special power-of-attorney, it
shall be deemed that Tenant has not waived any rights against Landlord or such
successor solely due to the use of the special power-of-attorney by Landlord.
Upon such attornment, this Lease shall continue in effect as a direct lease
between such successor landlord and Tenant upon and subject to all of the
provisions of this Lease.

     13.3 ESTOPPEL CERTIFICATES: Within fifteen (15) days after written notice
from Landlord, Tenant shall execute and deliver to Landlord, in recordable form,
a certificate in the form of Exhibit "I" stating (i) that this Lease is
unmodified and in effect, or in effect as amended, and stating all amendments;
(ii) the amount of Base Rent; (iii) the date to which Base Rent has been paid in
advance; (iv) the amount of any security deposit, prepaid rent or other payment
constituting rent which has been paid; (v) whether or not Tenant or Landlord is
in default under this Lease; and (vi) such other matters as Landlord shall
reasonably request. Tenant's failure to deliver such estoppel certificate within
such fifteen (15) day period shall be conclusive upon Tenant for the benefit of
Landlord, and any successor in interest to Landlord, that this Lease is in
effect and has not been amended except as may be represented by Landlord, no
rent has been paid more than thirty (30) days in advance and neither Landlord
nor Tenant is in default under this Lease. If Tenant fails to deliver such
estoppel certificate within such fifteen (15) day period, then Tenant agrees
that Landlord may then send a second notice and irrevocably constitutes and
appoints Landlord as its special attorney-in-fact to execute and deliver such
certificate to any third party ten (10) days after Landlord's second written
notice to Tenant to execute and deliver an estoppel certificate and Tenant fails
to do so. Landlord shall execute and deliver a similar estoppel certificate
within fifteen (15) days after written request by Tenant. If Landlord executes
documents on behalf of Tenant pursuant to the special power-of-attorney, it
shall be deemed that Tenant has not waived any rights against Landlord by reason
of the contents of the estoppel certificate signed pursuant to the special
power-of-attorney by Landlord.

     13.4 NON-DISTURBANCE AGREEMENT: Landlord shall, within ten (10) days after
the date of this Lease, obtain from Paul Revere Insurance Company and each other
holder of a Mortgage in existence at the time of execution of this Lease a duly
executed non-disturbance agreement in the form of Exhibit "H". With respect to
any Mortgages which are not in existence at the time of execution of this Lease,
Landlord shall obtain a non-disturbance agreement in the form of Exhibit "H"
duly executed in recordable form by any holders of any future Mortgage as a
condition to this Lease being subordinate and junior to such future Mortgage and
as a condition to the recordation of any such future Mortgage. Notwithstanding
any other provision in this Section 13, no special power-of-attorney in favor of
Landlord or agreement to attorn by Tenant shall have force or effect unless a
non-disturbance agreement substantially in the form of Exhibit "H" was
previously or concurrently delivered to Tenant.

                                   SECTION 14
                       SURRENDER OF PREMISES, HOLDING OVER

     14.1 SURRENDER OF PREMISES: By the Expiration Date, Option Expiration Date
or earlier termination of this Lease, (i) Tenant shall surrender to Landlord the
Premises, including without limitation all Alterations, in Good Condition
(except for destruction to the Premises covered by Section 9) except for
Alterations that Tenant is obligated to remove under Section 7.9, (ii) Tenant
shall remove all its Personal Property and perform all repairs and restoration
required by the removal of any Alterations or Personal




<PAGE>   34



Property at its sole cost, and (iii) Tenant shall surrender to Landlord all keys
to the Premises (including without limitation any keys to exterior or interior
office doors) and all permits, validations, keycards, passes, and similar items
with respect to the Premises and parking lot. Landlord may elect to retain or
dispose of in any manner any Alterations or Personal Property that Tenant does
not remove from the Premises on the Expiration Date, Option Expiration Date or
earlier termination of this Lease as required by this Lease by giving written
notice to Tenant. Title to any such Alterations or Personal Property that
Landlord elects to retain or dispose of shall vest in Landlord. Tenant waives
all claims against Landlord for any damage to Tenant resulting from Landlord's
retention or disposition of any such Alterations or Personal Property after the
Expiration Date or earlier termination of this Lease. Tenant shall be liable to
Landlord for Landlord's costs for storing, removing or disposing of any such
Alterations or Personal Property. If Tenant fails to surrender the Premises to
Landlord on the Expiration Date or earlier termination of this Lease, Tenant
shall indemnify and defend Landlord against all liability, loss and claims
resulting from such failure including without limitation any claim for damages
made by any other tenant or subtenant.

     14.2 HOLDING OVER: If Tenant, with Landlord's written consent, remains in
possession of the Premises after the Expiration Date, Option Expiration Date or
earlier termination of this Lease, such possession by Tenant shall be deemed to
be a month-to-month tenancy terminable on thirty (30) days written notice given
at any time by Landlord or Tenant. During any such month-to-month tenancy,
Tenant shall pay as Base Rent one hundred twenty-five percent (125%) of the Base
Rent in effect immediately prior to the Expiration Date or earlier termination
of this Lease, as the case may be. All provisions of this Lease except for those
pertaining to the Term shall apply to such month-to-month tenancy.

                                   SECTION 15
                               DELAY IN OCCUPANCY

     15.1 Definitions:

         (a) "Landlord Delays" shall have the meaning set forth in Paragraph 10
of the Work Letter (Exhibit "C").

         (b) "Unavoidable Delays" shall have the meaning set forth in Paragraph
11 of the Work Letter.

     15.2 Delay In Occupancy:

         (a) If, as of November 29, 1994, Tenant's Occupancy or Substantial
Completion has not occurred and there are more than one hundred and eighty-one
(181) days of combined Landlord Delay and Unavoidable Delay, this Lease shall,
at Tenant's option, terminate. If, as of November 29, 1994, Tenant's Occupancy
or Substantial Completion has not occurred and there are more than one hundred
and eighty-one (181) days of Unavoidable Delay, this Lease shall, at Landlord's
option, terminate. If, as of November 29, 1994, Tenant's Occupancy or
Substantial Completion has not occurred and there are more than one hundred and
eighty-one (181) days of combined Landlord Delay and Unavoidable Delay and
Tenant is not using reasonable efforts to obtain Substantial Completion, this
Lease shall, at Landlord's option, terminate.

         (b) If the Commencement Date is later than June 1, 1994 and there are
more than fourteen (14) days of Landlord Delay, Landlord shall pay to Tenant
that portion of rent at Tenant's address or other location that exceeds Base
Rent ("Reimbursed Rent") and moving and storage costs attributed solely to the
delay in the Commencement Date ("Reimbursed Moving and Storage Cost") from June
1, 1994 until the Commencement Date or July 5, 1994 whichever is earlier. If the
Commencement Date is later than July 5, 1994 and there are more than thirty-four
(34) days of Landlord Delay, Landlord shall pay to Tenant Reimbursed Rent and
Reimbursed Moving and Storage Cost from June 1, 1994 until the Commencement Date
or September 6, 1994 whichever is earlier. If the Commencement Date is later
than September 6, 1994 and there are ninety-seven (97) days of Landlord Delay,
Landlord shall pay Tenant Reimbursed Rent and Reimbursed Moving and Storage Cost
from June 1, 1994 until the Commencement Date or November 29, 1994 whichever is
earlier. If the Commencement Date is later than November 29, 1994 and there are
more than one hundred eighty-one (181) days of Landlord Delay, then Landlord
shall pay Tenant Reimbursed Rent and Reimbursed Moving and Storage Cost from
June

<PAGE>   35



1, 1994 until the Lease is terminated as set forth in Section 15.2(a), except
that Landlord shall not be obligated to pay Reimbursement Rent and Reimbursed
Moving and Storage Costs for any period beyond June 1, 1994 through November 29,
1994.

         (c) Landlord shall have no liability for Landlord Delay or Unavoidable
Delay except as specifically set forth in Sections 1.4 and 15.2 of this Lease.

         (d) Tenant's occupancy of the Premises at any time shall conclusively
be deemed a waiver by Tenant of this Section 15 except for any sums Landlord may
owe to Tenant pursuant to this Section 15.

                                   SECTION 16
                               GENERAL PROVISIONS

     16.1 BROKERS: Tenant represents that, except as set forth in this Section
16.1, no real estate broker, agent, finder, or other person is responsible for
bringing about or negotiating this Lease and that Tenant has not dealt with any
real estate broker, agent, finder, or other person with respect to this Lease in
any manner. Tenant shall indemnify and defend Landlord against all liability,
costs, expenses and charges (including without limitation attorneys' fees and
disbursements) arising from any claims that may be made against Landlord by any
real estate broker, agent, finder, or other person alleging to have acted on
behalf of or to have dealt with Tenant, prior to the Commencement Date and
during the Term. Landlord retained CB Commercial Real Estate Group Inc. ("CB
Commercial") as a leasing broker and shall be responsible for all commissions
paid to CB Commercial regarding this Lease. Tenant retained Cushman Realty
Corporation ("Cushman"), as exclusive agent for Tenant. Landlord shall pay to
Cushman a real estate brokerage commission ("Commission") of five percent (5%)
of the Base Rent (less the Rent Abatement for the first five (5) years of the
Term) and two and one-half percent (2 1/2%) of the Base Rent for years six (6)
through ten (10) of the Term payable one-half (1/2) upon the complete execution
of the Lease and one-half (1/2) upon the Commencement Date and upon the
occupancy of the Premises by Tenant. In the event Landlord fails to pay the
Commission to Cushman on or before the date(s) due, as specified herein, Cushman
may send written notice to each of Landlord and Tenant of such failure. If
Landlord fails to pay such amount(s) within thirty (30) days after the date of
such notice, Tenant shall have the option, but not the obligation, to pay
Cushman any balance due of the Commission and to offset the amount paid,
together with interest at the rate of ten percent (10%) per annum, against
Tenant's next rent due under this Lease.

     16.2 NOTICES: Any notice, demand, request, consent, approval, or
communication that either Landlord or Tenant desires or is required under this
Lease to give to the other or any other person shall be in writing and either
served personally or sent by certified prepaid, first class U.S. Federal Express
mail or other overnight delivery service that provides written confirmation of

portion of the Premises, Landlord, on consummation of the sale or transfer,
shall be released from liability under this Lease, except for the actions of

consummation. If any security deposit or prepaid rent has been paid by Tenant,
Landlord may transfer the security deposit and/or prepaid rent to Landlord's
successor-in-interest and on such transfer Landlord shall be discharged from any
further liability arising from the security deposit or prepaid rent.

     16.5 ATTORNEYS' FEES: If Landlord or Tenant becomes a party to any
litigation concerning this Lease, the Premises, or the Project by reason of any
act or omission of the other or its agents, employees, officers, independent
contractors, licensees, invitees, visitors or customers, (and not by any act or
omission of the one that becomes a party to that litigation or its agents,
employees, officers, independent contractors, licensees, invitees, visitors or
customers), the one that causes the other to become involved in such litigation
shall be liable to the other for reasonable attorneys' fees, court costs, and
other expenses incurred by it in such litigation. If Landlord or Tenant
commences an action against the other arising out of or in connection with this
Lease, the prevailing party (as determined by the court) shall be entitled to
recover from the losing party reasonable attorneys' fees, court costs, and other
expenses incurred by the prevailing party in such litigation.

     16.6 MERGER: A voluntary or other surrender of this Lease by Tenant, or a
mutual cancellation of this Lease, or a termination by Landlord, shall not work
a merger, and shall, at the option of Landlord, terminate any existing subleases
or may, at the option of Landlord, operate as an assignment to Landlord of any
such subleases.

     16.7 TIME OF ESSENCE: Time and strict and punctual performance are of the
essence with respect to each provision of this Lease.

     16.8 SUCCESSOR IN INTEREST: Subject to Section 11, this Lease shall be
binding on and inure to the benefit of Landlord and Tenant and their successors
in interest.


<PAGE>   37



     16.9 EASEMENTS: Landlord may, from time to time, grant such easements,
rights and dedications that Landlord deems necessary or desirable, and cause the
recordation of parcel maps and restrictions, provided such easements, rights,
dedications, maps and restrictions do not unreasonably interfere with the use of
the Premises by Tenant. Tenant shall promptly sign any documents or instruments
to accomplish the foregoing upon request by Landlord, and failure to do so shall
constitute a material breach of this Lease. Tenant irrevocably appoints Landlord
as Tenant's special attorney-in-fact to execute and deliver such documents or
instruments on behalf of Tenant should Tenant refuse or fail to do so.

     16.10 GOVERNING LAW: This Lease shall be interpreted in accordance with the
laws of the State of California.

     16.11 INTEGRATION: This Lease contains all the agreements between Landlord
and Tenant relative to this Lease and cannot be amended or modified except by a
written document executed by Landlord and Tenant. This Lease shall be deemed
prepared by both parties, and the fact that one party actually drafted this
Lease shall not affect the interpretation of any provision thereof.

     16.12 PROVISIONS ARE COVENANTS AND CONDITIONS: All provisions, whether
covenants or conditions, to be performed or observed by Landlord and Tenant
shall be deemed to be both covenants and conditions.

     16.13 PERSON AND GENDER: Whenever the singular number is used in this
Lease, the same shall include, when appropriate, the plural; and each gender
shall include, when appropriate, any other genders; and the word "person" shall
include, in addition to a natural person, when appropriate, a corporation, firm,
partnership, joint venture, trust, estate or other entity.

     16.14 SEVERABILITY: If any provision of this Lease is held by a court to be
unenforceable or invalid for any reason, the remaining provisions of this Lease
shall be unaffected by such holding.

     16.15 LIMITATIONS ON LANDLORD'S LIABILITY: If Landlord is in default under
this Lease, and as a consequence, Tenant recovers a money judgment against
Landlord, such judgment shall be satisfied only out of the proceeds of sale
received upon execution of such judgment and levy against the right, title and
interest of Landlord in the Project, and out of rent or other income from the
Project receivable by Landlord or out of the consideration received by Landlord
from the sale or other disposition of or any part of Landlord's right, title and
interest in the Project, except for that portion of the judgment that
specifically pertains to Landlord's (i) failure to timely pay taxes or
insurance, (ii) failure to refund Tenant's security deposit, (iii) fraudulent,
willful or intentional acts or misrepresentations, (iv) failure to apply
insurance or condemnation proceeds as required by the Lease, and (v) failure to
remit, to the persons entitled thereto, any funds paid by Tenant to Landlord for
work or materials on the Premises. Except as specifically provided in this
Section, neither Landlord nor the partners comprising Landlord (if any) shall be
personally liable for any deficiency.

     16.16 HEADINGS AND EXHIBITS: The Section and subsection headings of this
Lease shall have no effect on its interpretation. Any exhibits referred to in
this Lease are incorporated in it by reference.

to Landlord under this Lease shall be in United States currency.

     16.18 TENANT'S FINANCIAL STATEMENTS: Within fifteen (15) days of written
notice from Landlord, Tenant agrees to deliver to Landlord or any lender or
buyer designated by Landlord, at no cost to Tenant, such financial statements of
Tenant that have most recently been prepared, as may be reasonably required by
Landlord, any lender or buyer. Such financial statements shall include the past
three (3) years' financial statements of Tenant if requested in writing by
Landlord. Such financial statements shall be kept confidential and Landlord
shall take all reasonable steps necessary to ensure such confidentiality.


<PAGE>   38




     16.19 NO OPTION: The submission of this Lease by Landlord, its agent or
representative for examination or execution by Tenant does not constitute an
option or offer to lease the Premises upon the terms and conditions contained in
this Lease or reservation of the Premises in favor of Tenant, it being intended
that this Lease shall only become effective upon the execution of the Lease by
Landlord and Tenant and delivery of a fully executed Lease to both parties.

     16.20 RECORDATION OF LEASE: Either Landlord or Tenant may, at its election,
record a Memorandum of Lease and each party shall cooperate with the other in
connection therewith.

     16.21 NO VIOLATION OF OTHER AGREEMENTS: Tenant hereby warrants and
represents that neither its execution of or performance under this Lease shall
cause Tenant to be in violation of any agreement, instrument, contract, law,
rule or regulation by which Tenant is bound and, in addition to all other

EXHIBIT D

All defined terms in this Exhibit D shall have the same meaning as in the Lease.

I. GENERAL

   A.   Pacific Corporate Park is designed to be a highly successful office
        building center. It is expected that tenant improvements and signage may
        represent a variety of design styles. PacCor Partners ("Landlord")
        intends to provide Tenant with reasonable latitude with this aspect of
        design. At the same time, Landlord will discourage tenant it
        improvements and signage design that would conflict significantly with
        the general design of these buildings. These matters are more fully
        addressed in section Vl of these Building/Tenant Improvement Standards
        For Pacific Corporate Park ("Building Standards").

        In providing the Building Standards, it is Landlord's intent to simplify
        the effort of Tenant in securing Landlord's approval of tenant
        improvements and/or alterations to be constructed by Tenant through a
        clear understanding of the responsibility of each party. The Building
        Standards are intended to aid Tenant in designing its improvements.

        In the event of any conflict between the Building Standards and the
        Office Lease (the "Lease"), the provisions of the Lease will govern.

II. LANDLORD'S RESPONSIBILITIES

   A.   Responsibilities of Landlord are as follows:

        1.     Make available to Tenant and Tenant's Representatives a person
               designated by the Landlord to be responsible for providing
               information, review of Tenant's drawings, to have final approval
               authority for all submittals, and to resolve disputes between
               tenants.

     to Landlord's approval as to construction details, size, configuration,
     location, and support.

W.   Tenant's Contractors shall obtain approval from Landlord prior to

     thereof, Tenant's Contractors shall (i) comply with all governmental rules

     subcontract, and all such guarantees shall be so written so that same shall
     inure to the benefit of both Tenant and Landlord, as their respective
     interests may appear, and so that same may be directly enforced by Tenant
     or Landlord. Tenant shall provide Landlord with an assignment or other
     assurance necessary to perfect Landlord's right to enforce any such
     guarantee.

     liability, cost or expense incurred by Landlord in connection with any such

Re:   Pacific Corporate Park
      5930 and 5935 Cornerstone Court
      HVAC System

Dear Terry:

The subject buildings are serviced by a "Tri-Water" water source heat pump
system. The central plant, which houses a separate cooling tower, boiler and
recirculating pump for each building, is located in the parking area north of
building A. The condenser water is piped underground to each building and
connected to the fire sprinkler system which is routed throughout both
buildings. The individual water source heat pumps are then connected to the
fire sprinkler piping as a part of the tenant improvement.

The cooling towers installed are rated @ 350 GMP which would provide the
equivalent of approximately ?? tons of air conditioning capability for each
building. There is a 4 wire energy management loop that is routed from the
central plant to each building for connection to future tenant Water Source
Heat Pump ("WSHP") units. This allows the tenant to communicate with the
central plant .a provide after hours cooling.

As part of the tenant improvement buildout, the following should be utilized
as guidelines for a minimum standard:

       1. Suspend WSHP units above the ceiling utilizing 1 in. spring
isolation for vibration and sound attenuation.

       2. Type L copper piping with hard solider should be utilized for the
condenser water piping to the individual WSHP units. Automatic flow controls
are required for each unit.

       3. The return air must be ducted and both supply and return ducts must be

Lease (the "Effective Date") shall be the date that Assignor vacates the entire
Premises to move to its new facility. The parties currently estimate that the
Effective Date will occur on September 6, 1998. Assignor shall give written
notice to Assignee (the "Effective Date Notice") six (6) months prior to
Assignor's then estimated Effective Date (the "Estimated Effective Date"). In
addition, Assignor shall give Assignee regular updates as to the status of
Assignor's schedule to vacate the Premises and shall promptly notify Assignee of
any changes to the Estimated Effective Date, provided that the Estimated
Effective Date shall not be earlier than the date set forth in Assignor's
Effective Date Notice without Assignee's consent. In addition, Assignor shall
give Assignee at least thirty (30) days prior written notice of the actual
Effective Date to allow Assignee to schedule its move in to the Premises. If
Assignor does not deliver the Effective Date Notice by September 6, 1998, or if
the Effective Date does not occur by March 6, 1999, Assignee shall have the
right to terminate this Assignment by giving written notice of termination to
Assignor, and, upon such termination, neither party shall have any further
rights or obligations under this Assignment. On the Effective Date, Assignor
shall deliver possession of the Premises to Assignee in the condition required
by Section 14.1 of the Lease as such provision applies to the expiration or
earlier termination of the Lease and with all Building systems in good

working order. Except as provided in the preceding sentence, the Premises shall
be delivered to Assignee in its "as-is" condition existing on the date of this
Assignment, subject to normal wear and tear between the date of this Assignment
and the Effective Date.

        2. Assumption. Assignee hereby accepts the assignment, and assumes and
agrees, for the benefit of Assignor and Landlord, to be responsible for and
further agrees to faithfully perform and be bound by all of the terms,
covenants, conditions, provisions and agreements of the Lease from and after the
Effective Date.

        3. Indemnity. Assignor agrees to indemnify, defend (with counsel
reasonably acceptable to Assignee) and hold Assignee and its officers,
directors, shareholders, agents, employees and affiliates harmless from and
against any and all claims, actions, liabilities, damages, costs and expenses
(including, without limitation, attorneys' fees and costs incurred in connection
therewith or to enforce this indemnity obligation) arising from or relating to
any obligations to be performed by Assignor under the Lease prior to the
Effective Date and/or any acts or omissions of Assignor in connection with the
Lease prior to the Effective Date. Assignee agrees to indemnify, defend (with
counsel reasonably acceptable to Assignor) and hold Assignor and its officers,
directors, shareholders, agents, employees and affiliates harmless from and
against any and all claims, actions, liabilities, damages, costs and expenses
(including, without limitation, attorneys' fees and costs incurred in connection
therewith or to enforce this indemnity obligation) arising from or relating to
any obligations to be performed by Assignee under the Lease on or after the
Effective Date and/or any acts or omissions of Assignee in connection with the
Lease on or after the Effective Date. Notwithstanding the foregoing, if
Assignee's move-in is phased pursuant to Section 6 below, Assignor's indemnity
obligation shall continue, and Assignee's indemnity obligation shall not
commence, with respect to each phase until Assignor delivers possession of such
phase to Assignee.

        4. Security Deposit. Notwithstanding the assignment of the Lease as
provided herein, Assignor shall retain all rights to the security deposit
delivered to Landlord under the Lease in the amount of $48,984 (the "Security
Deposit"). The Security Deposit shall be paid by Landlord directly to Assignor
in accordance with the terms of the Lease. Assignee agrees to immediately
deliver the Security Deposit to Assignor if the Security Deposit is paid to
Assignee notwithstanding the preceding sentence. In addition, Assignee agrees to
immediately reimburse Assignor for any deductions from the Security Deposit made
by Landlord in accordance with the Lease as a result of Assignee's failure to
perform its obligations under the Lease from and after the Effective Date.
Assignee shall also be obligated to pay (or to cause Landlord to pay) to
Assignor an amount equal to the Security Deposit if Assignee and Landlord (a)
terminate the Lease and enter into a new lease of the Premises or (b) modify the
material terms of the Lease.

        5. Covenants, Representations and Warranties of Assignor. Assignor
hereby represents and warrants to Assignee that (i) Assignor has not previously
made an assignment of Assignor's rights under the Lease to any other party, (ii)
that the Lease is in full force and effect and has not been modified or amended
except as provided in the First Amendment and the Second Amendment described
above, (iii) the copies of the Lease delivered by Assignor to Assignee are true,
correct and 

                                       2
<PAGE>   86

complete copies of the Lease, (iv) neither Assignor nor, to Assignor's
knowledge, Landlord is in default of their respective obligations under the
Lease and (v) the Commencement Date of the Lease occurred on June 1, 1994. Such
representations and warranties shall be true and correct in all material
respects as of the date of this Assignment and as of the Effective Date. Between
the date of this Assignment and the Effective Date, Assignor agrees to promptly
deliver to Assignee copies of any and all notices relating to the Lease and/or
the Premises, to timely perform all of its obligations under the Lease, and not
to modify or amend the Lease or exercise any rights or remedies under the Lease
without Assignor's prior written approval, which approval shall not be
unreasonably withheld.

        6. Phased Occupancy. Assignor and Assignee agree to cooperate, in good
faith, if Assignor elects to phase-out of the Building at different times.
Assignor shall give written notice of such election to Assignee stating the
dates on which Assignor intends to vacate each portion of the Building. The
parties acknowledge and agree that each phase of the Building to be vacated by
Assignor must be sufficiently demised and otherwise appropriate for Assignee's
phased move-in and use. In the event of a phased move-in, Assignee shall only be
responsible for a proportionate share of the obligation to pay rent and other
amounts due under the Lease and the performance of other obligations under the
Lease based on a fraction, the numerator of which is the rentable area of the
portion of the Premises so occupied by Assignee, and the denominator of which is
the total rentable area of the Premises. In such event, Assignor shall remain
liable for its proportionate share of all payment and performance obligations
under the Lease. In no event shall the phase-out period be longer than six (6)
months after the date possession of the first phase of the Building is delivered
to Assignee.

        7. Termination of Existing Sublease. Assignor, as sublessee, and
Assignee, as sublessor, have entered into that certain Sublease dated September
24, 1996 (the "Sublease") relating to space within the building located at 6020
Cornerstone Court West in San Diego, California. The parties agree that the
Sublease shall terminate on the date Assignor fully vacates such space in
accordance with the Sublease and the parties shall be released of all
obligations under the Sublease from and after such date. Assignor shall give
Assignee at least six (6) months prior written notice of the date upon which it
will vacate such space.

        8. Commission. Except for The Irving Hughes Group, Inc. ("Broker"),
Assignor and Assignee each represent and warrant to the other that it has not
dealt with any party, whether or not licensed, that may be entitled to a
commission, finder's fee or similar compensation in connection with this
Assignment. Assignor and Assignee each agree to indemnify, defend (with counsel
reasonably acceptable to the other) and hold harmless the other party from and
against all claims, damages, liabilities, costs and expenses (including
attorneys' fees and costs incurred in connection therewith or to enforce this
indemnity agreement) arising from or relating to the indemnifying party's breach
of the foregoing representation and warranty.

        9. Improvements. Assignee may desire to make improvements to the
Premises after the Effective Date. Assignor agrees to cooperate with Assignee to
apply for and seek Landlord's consent to such improvements in accordance with
the provisions of the Lease.

        10. Miscellaneous. In the event any action or proceeding is brought by
either party against the other relating to or arising from this Assignment or to
enforce or interpret any provision hereof, the prevailing party shall be
entitled to recover from the other party all costs and fees incurred in
connection therewith, including without limitation, fees and costs of attorneys,
experts and consultants in connection with such action or proceeding, the
enforcement of any judgment and any appellate proceedings. This Assignment and
all terms and conditions contained herein shall be binding upon and inure to the
benefit of the successors and assignors of the parties. This Assignment
constitutes the entire agreement between the parties with respect to the matters
set forth herein and supersedes all prior and contemporaneous agreements and
understandings, whether written or oral, pertaining to any such matters,
provided that the Sublease shall not be affected excepted as provided herein.
This Assignment may not be modified or amended except by a written agreement
signed on behalf of each of the parties. This Assignment shall be construed and
enforced in accordance with the internal laws of the State of California. This
Assignment may be executed in counterparts, each of which, when executed and
delivered, shall constitute one fully executed original.

        11. Notices. Any notice pursuant to this Assignment shall be in writing
and shall be addressed as follows:

                               CONSENT OF LANDLORD

        In consideration of the covenants and agreements contained in this
Assignment, Landlord hereby consents to the foregoing assignment of the Lease by
Assignor to Assignee, provided, however, that (i) the consent of Landlord herein
shall not be deemed to in any way release or diminish the liability of Assignor
to Landlord; and (ii) the consent of Landlord herein shall not be deemed a
consent to any future assignment, sublease or transfer of the Premises, all of
which shall require Landlord's consent. Such consent shall not be subject to the
requirement set forth in Section 11.1(d) of the Lease that any proposed
assignment be consummated within 180 days after Landlord's consent, and
Landlord's consent shall remain valid and in full force and effect if the
assignment becomes effective on the Effective Date as set forth in the
Assignment. Landlord confirms that, as of the date of this consent, (a) the
Lease is in full force and effect and has not been modified or amended except as
provided in the First Amendment and the Second Amendment and (b) Landlord is not
aware of any default under the Lease by Assignor. Prior to the Effective Date,
Landlord agrees to give Assignee written notice of any default by Assignor under
the Lease and to give Assignee an opportunity to cure any such default for a
period following such notice equal to the applicable cure period under the
Lease.
