OVERVIEW
 
    Centura Software Corporation (the "Company" or "Centura"), formerly Gupta
Corporation, provides a suite of products usable by application developers to
build and deploy component based distributed business applications. Centura
products include an embedded database that scales from Smart Cards to the Web,
and application development tools for Windows and Web clients. Centura products
are designed to be deployed in both thin- and fat-client environments, using
business logic objects that can be reused in multi-tier architectures in
distributed environments (The Internet is referred to hereinafter as the "World
Wide Web" or the "Web" and corporate internal Webs are referred to as
"Intranets"). The Company's product lines include a family of embedded
databases, (SQLBASE), application development tools, (CENTURA TEAM DEVELOPER,
THE 32-BIT VERSION OF SQLWINDOWS, SQLWINDOWS AND CENTURA NET.DB) and PC to
mainframe connectivity products (SQLHOST). Now in its seventh generation,
SQLBASE was the first Relational Database Management System ("RDBMS") available
in the PC and PC LAN environment offering similar RDBMS functions previously
found only in high-end databases. The Company's products have historically been
market leaders in the Windows client/server environment, used both in
work-group/departmental business applications, as well as packaged applications
sold by third party software vendors to small and medium size businesses. The
Company is continuing to enhance its existing Windows client product line. At
the same time, the Company is enhancing its products into new market
opportunities for thin-clients (the Web, Portable Device Applications ("PDAs")
and smart appliances. In these markets, a small memory requirement (or
"footprint"), client/server or embedded application and database architecture
has a natural fit.
 
    The Company's embeddable database, SQLBASE, is a robust, small footprint
RDBMS, which requires no database administrator ("DBA"). Business applications
that embed SQLBASE operate with a single set of source code on a desktop PC, a
PC LAN, the Web, and connected mobile client environments. The Company's
development tools, CENTURA TEAM DEVELOPER and SQLWINDOWS, are 4GL object
oriented tools offering improved programmer productivity. The Company recently
introduced CENTURA NET.DB, a browser-based SQL to HTML Web authoring tool.
CENTURA NET.DB makes it easy to connect corporate databases with end users,
providing dynamic access to SQL databases in JavaScript enabled Web browsers. In
addition, as CENTURA NET.DB is browser based, it can run on any client platform
capable of running a browser. SQLHOST allows organizations to integrate DB2 or
legacy data into a client/server environment without compromising performance,
control, or security.
 
    The primary customers of Centura products are application developers,
including Fortune 1000 developers who deploy Centura products throughout company
branch offices and customers' offices, Independent Software Vendors (ISVs) who
develop and deploy shrink-wrapped, packaged applications for small and medium
size business, and Value Added Resellers who develop customized software for
end-users. A new set of customers is emerging which embed SQLBASE in smart
and/or mobile electronic devices, such as the government of Mexico which imbeds
SQLBASE in Smart Cards for NAFTA export control. Some application developers
deploy both the embedded database and the application development tools in their
applications. Other developers deploy only the embedded database, connecting
SQLBASE to other business logic application tools such as Java or Visual Basic,
or to application development tools sitting on top of other, larger databases.
 
    The Company has established multiple distribution channels that provide
broad market coverage for its products and address the specific needs of its
varied customer segments worldwide. The Company's
 
                                       2
<PAGE>
products are used in at least 75 countries. Its customers include include
Automatic Data Processing ("ADP"), Aurum, CamData, Citibank N.A., Daimler-Benz,
Ford Motor Company, SQL Financials, IFS, Help Desk Software, Norfolk Southern,
Ontario Hydro, Lilly Software, Siemens-Nixdorf Informations Systeme AG
("Siemens-Nixdorf"), The Southern Company, United Airlines, United Parcel
Service, Deutsch Bank, M-5, Xerox, Computer Asssociates, and the governments of
Mexico, France, Australia and the United Kingdom.
 
INDUSTRY OVERVIEW
 
    Over the past few decades, organizations have increasingly used their
computing systems to improve their management of mission-critical business
functions, such as manufacturing, distribution, customer support, finance and
administration. In the 1970s and 1980s, computing environments for such
applications were dominated by large computer systems with a mainframe or
minicomputer acting as a host processor for terminals with very limited
computing power. These traditional host-based systems are expensive to install
and maintain, and related software development is typically time consuming. In
addition, management of and access to the critical information resources
residing on these systems is generally limited to a staff of dedicated
management information systems ("MIS") professionals and relatively inaccessible
to a broader base of users.
 
    In the late 1980s, a new architecture for information processing called
"client/server" computing emerged to address the many shortcomings of host-based
systems. Client/server computing typically provides increased functionality at a
lower hardware and software cost, an easier-to-use operating environment and
information access by a broader base of users. A client/server system typically
consists of multiple intelligent desktop client computers linked in a network
with high performance server computers. The client replaces the dumb terminal
employed in host-based systems and has resident software that manages the user
interface and performs local data access and manipulation. The server performs
many of the functions previously performed by the host in a host-based system,
such as network management, data storage, printing, communications, and data
security and integrity.
 
    The widespread use of increasingly powerful PCs has made it possible for
organizations to deploy client/server systems based on local area networks
("LANs"), thereby increasing the benefits of the large existing installed base
of PCs. A LAN is a group of computers connected for the purpose of sharing data
and networked resources such as printers and data storage devices. PC
client/server computing combines the benefits of host-based systems with the
cost-effectiveness and ease of use of PCs. Other factors increasing the
deployment of PC client/server systems include the continued decline in the
costs of high-performance PCs and improvements to PC operating systems,
including easy-to-use graphical user interfaces such as those incorporated in
Microsoft Corporation's ("Microsoft's") Windows and Windows 95, and Windows NT
operating systems. In addition, connectivity software is available to enable PC
clients to access varied data sources, including existing mainframes and
minicomputers, thereby protecting an organization's investment in these
host-based systems.
 
    Today, the traditional fat-client PC and PC LAN environment continues to
exist as a platform for business applications. At the same time, new form
factors are emerging with a need for the company's products. As suggested by the
creation of network computers there is an increasing trend among end-users to
move the business logic from the PC to the server, which generally provides an
easier way to maintain consistent and secure up to date applications and data.
In addition, due to the proliferation of PCs to millions of end-users, the costs
of maintaining a PC has become a matter of concern to many enterprises. This
client/server architecture is referred to as a thin-client, and can refer to
both a Windows network computer as well as a Web browser client. The Company
believes the introduction of small, smart server centric access devices, such as
palm top organizers, smart phones, PDAs and WebTV-TM- will continue to increase.
This new multi- or n-tier, thin-client establishes a need for a new software
application architecture, creating an opportunity for software tools such as
those available from the Company that fit the needs of the thin-client world.
 
                                       3
<PAGE>
    The Web is an example of a thin-client architecture. The Web opens the
corporate data sources and applications to new and highly distributed end-users
who typically operate through standard platform-independent user environments,
commonly known as "browsers" which typically also run on PCs, but will
increasingly be accessible through mobile, smart devices. Industry analysts are
expecting millions of new small, form factors that will provide mobile access to
servers over the next 5 years. Similar to the rapid emergence of PCs and LANs in
the late 1980s and early 1990s, the emergence of the Web and multiple types of
access devices raises new challenges and opportunities for organizations and the
business applications they choose to manage their business. More than ever
before, the use of technology will impact the bottom line of a business, as
recent studies continue to support the effectiveness of the Web for performing
business transactions. Corporations will increasingly provide direct, electronic
access to back office data to their employees, customers and suppliers.
 
    Web-based systems can be deployed as simple departmental systems or highly
distributed networks that can provide access to end-users in locations and
geographies outside the corporate network. There is also an increasing trend
toward disconnected or so-called distributed or "mobile" applications where a
stand-alone PC, laptop PC, Smart Card or other thin-clients manages data locally
and may be connected asynchronously to centralized, host-based data sources.
Such systems can also be deployed as part of an overall enterprise system
combining stand-alone PCs, multiple PC client/servers and enterprise-wide
servers.
 
    With the continued price/performance curve of the microprocessor, new form
factors of thin-clients will continue to evolve and proliferate, such as palm
top organizers, PDAs, smart phones and WebTV-TM-. Industry analysts are
forecasting shipments of millions of units of new smart, thin-clients. These
mobile devices can instantaneously connect end-users to remote server
information, available for either information or transactions. These new
thin-clients are catalysts for new technologies and new applications and provide
an opportunity for a new generation of business applications taking advantage of
the thin-client server-centric access architecture. These thin-clients need
robust, small footprint embedded databases.
 
    The increase in the deployment of PCs--in both traditional fat client/server
environments and increasingly for implementation and access to thin-client
Web-based or multi-tier environments--is fueling demand by organizations for new
applications utilizing this thin-client architecture.
 
    One other industry trend is changing the architectural design of today's
business applications. Organizations want to integrate the data generated by the
back office throughout the enterprise and, increasingly, with its customers.
Customer service account representatives need access to the latest information
about corporate customers and sales activity and desire electronic connection or
integration to company accounting records. Organizations generally want to
eliminate the information time lag between disparate information systems
throughout the enterprise and the external supply chain and tend to prefer
enterprise wide applications, regardless of their size. It would be unlikely
that one software vendor can provide all the applications required within an
organization. What is important is that the business logic of one application
can be shared between other applications operating in the organization. This
integration between disparate applications places an increased demand for
business applications built with components and objects. Existing software
applications and new software applications are being redesigned to meet the
changing demands for integration and access to metadata, and center on the use
and design of components, objects and reusable code that can operate in a
distributed COM/DCOM environment. Additionally, Java has emerged as a clear
player in the development arena. Java offers a great opportunity to help deliver
and use server side components via Java Enterprise Beans deployed under the
CORBA Architecture. Java objects running on the server will provide the
scalability and platform independence needed to build distributed applications.
 
    The Company was founded to provide application development tools deployed in
applications operating in the Windows client/server environment. In 1996, 1997
and 1998 the Company announced and delivered extensions that operate in a Web
browser client/server environment. The Company will continue
 
                                       4
<PAGE>
to invest in tools for both the thin- and fat-client Windows world, and will
take advantage of new opportunities for its products in the emerging thin-client
world of the Web and smart mobile devices, which is a natural extension of
Intranet and network-centric computing. The Company's current product offerings
are fully compliant with and accommodate data structures for years beginning
after January 1, 2000.
 
COMPANY STRATEGIES
 
    The Company products have historically been used by its customers to design
client/server applications with Windows clients. As the client/server world
continues to evolve with new types of clients accessing a server-centric
architecture, the Company is transitioning its products to meet the needs of
developers whose applications link the new thin-clients (the Web, PDAs, smart
phones, etc.) to servers. At the same time, the Company will continue to evolve
its object oriented application development tools so that class libraries can
use and generate components and objects in a distributed COM/DCOM and CORBA
environment. Key elements of its strategies are highlighted below. Finally, the
Company believes its small footprint RDBMS can be embedded in other types of new
smart electronic devices, such as copiers and routers.
 
    EMBEDDED DATABASE.  The Company believes several industry trends will drive
demand for a robust, non-DBA, small footprint embedded database. An embedded
database is integrated with business application code, and is invisible to the
end user. An embedded database has high server programmability, allowing
developers to control the database server from the applications, reducing the
need for a DBA through self tuning and self recovery functions. A robust
embedded database is scalable, and can support hundreds of simultaneous users.
 
    One growth factor for embedded databases is the expectation by certain
industry analysts that the next growth opportunity for PCs is the implementation
of enterprise wide applications in mid-size businesses. This mid-size market is
being targeted by application vendors now selling to large corporations, as well
as application vendors now selling to small businesses. Both of these
application vendors may find their existing choice of a database is not
appropriate for the mid size business. Application vendors sold to Fortune 1000
customers typically run on top of large databases. These Fortune 1000 databases
generally require large license fees, a large footprint, and a requirement for
an in house DBA--attributes that do not match the mid-size business market
requirements. On the other hand, current small business application vendors will
discover their existing embedded database probably provides adequate response
for transactions happening with a small number of end-users, but will not scale
up to several hundred end-users, and will be unable to respond to the
transaction needs of mid-size companies. The demand for robust, non-DBA,
scalable, embedded databases that operate in either a LAN-based or Web-based
environment will continue to grow as more and more small and medium size
businesses buy and implement enterprise transaction-based applications. These
small and mid-size businesses do not have an internal DBA, and cannot afford the
expense of hiring such a person.
 
    The other trend impacting the growing need for embedded databases is the
emerging market for distributed, mobile thin-clients, such as WebTV-TM-, palm
top organizers and smart devices, such as cellular phones and Smart Cards. These
new thin-clients and smart appliances require a robust, small footprint embedded
database that can also synchronize and exchange data between a server and the
mobile client. SQLBASE EXCHANGE, the add-on product sold with SQLBASE, is a
database replication tool, enabling an embedded database on a mobile,
thin-client to easily exchange data with a remote server.
 
    With the proliferation of the Web, there is a growing need for small,
non-dba databases for use with common application development tools, such as
Java and Visual Basic. The SQLBASE API makes it easy for application developers
to connect SQLBASE within their application development process. SQLBASE
supports open connectivity to a variety of development tools, including Visual
Basic, Java and Visual C++, utilizing high performance ODBC and JDBC level 4.
SQLBASE offers a 100% Java JDBC driver (Level 4)
 
                                       5
<PAGE>
that permits Java developers to optimize their SQLBASE connectivity
requirements. Further, as part of the embedded oriented features of SQLBASE,
Centura currently offers external functions, which allow developers to call DLL
base procedures from Triggers and Stored Procedures. Due to the importance of
Java, it is the Company's intention to incorporate Java base external functions
in future releases of SQLBASE. There can be no assurance that the Company will
be successful in these efforts.
 
    The foregoing factors combine to create, what the Company believes, is a
compelling opportunity for the Company's embedded database products.
 
    APPLICATION DEVELOPMENT TOOLS.  The Company believes there will be a
continued demand for building applications that run in an n-tier environment,
with access to common, reusable business logic objects for both fat-clients and
thin-clients. CENTURA TEAM DEVELOPER is a 4GL, object-oriented development tool,
designed to maximize developer's investment in developing business logic code.
CENTURA TEAM DEVELOPER applications have native connectivity not only to
SQLBASE, but Oracle, Sybase and Microsoft SQLServer with the same set of APIs.
The same CENTURA TEAM DEVELOPER business logic can be deployed as both a Windows
and browser client, with minimal reprogramming of code, providing an easy
redefinition of application packages to support Internet-based
customer-to-supplier value chains. With the continued trend toward enterprise
wide applications, Centura expects a continued interest in the use of
application development tools that access and create components and business
logic objects available on either the server or the client. Developers will be
able to create new application solutions throughout the enterprise by
customizing and modifying existing components. These components will provide a
common linkage between disparate applications. Sales automation systems can be
linked to accounting systems, and companies can post and retrieve applications
via thin- and fat-clients--all possible by using common business logic
components created with CENTURA TEAM DEVELOPER. The Company expects that in the
future, a component's location on the network will become irrelevant to the
developer. Developers will expect to be able to compose, distribute, and debug
applications from any location. The Company plans to offer enhancements for
CENTURA TEAM DEVELOPER in 1998 that are designed to make it easy to manage and
distribute ActiveX components in a COM/DCOM distributed architecture. As Java
servlets or Java Beans can be invoked from COM interfaces, the Company intends
to enhance CENTURA TEAM DEVELOPER to be able to use these types of objects as
well as pure COM objects. In addition, it is the Company's intention that
CENTURA TEAM DEVELOPER may, in the future support integration with CORBA
environments to expose and use Java objects. There can be no assurance that the
Company will be successful in these efforts. The Company expects companies to
gradually move away from buying custom applications towards the building of new
systems by integrating and customizing existing components. The competitive
advantage will come from customizing off-the-shelf applications. This "buy and
customize" approach offers the best of both worlds: rapid development and the
ability to customize the application to meet existing business processes
requirements. The object architecture provided by CENTURA TEAM DEVELOPER is
conducive to individual customization of applications. This component, reusable
architecture, provides an advantage to the Company's application developers,
especially in sales situations where evaluation criteria might be the ease in
which components can be customized.
 
    CENTURA NET.DB is a Web authoring tool, enabling Webmasters or software
developers to design SQL to HTML dynamic queries deployed within any
JavaScript-enabled Web browser. CENTURA NET.DB is browser-based for both design
and deployment. CENTURA NET.DB requires no special SQL, HTML, CGI, Perl, or C/
C++ expertise--and there is no requirement for browser plug-ins and other server
software. The CENTURA NET.DB architecture is intelligent about its use of
resources, accessing only the business logic code necessary to satisfy a
user/program request, and enabling hundreds of simultaneous accesses on a single
NT server. The Company expects to offer a version of CENTURA NET.DB that will
enable transaction processing via the Web.
 
    TOTAL COST OF OWNERSHIP.  The Company's products are built to be cost
effective for both the software developer and the end user.
 
                                       6
<PAGE>
    The Company's products offer several advantages for the developer. The
Company's products are scalable, allowing a single set of source code to be
deployed on multiple platforms. Business applications that embed SQLBASE can be
installed as a single user desktop or a server environment from a single SKU.
Applications written with CENTURA TEAM DEVELOPER can interface with SQLBASE, as
well as Oracle, with a single set of code. This single set of source code
approach may reduce the amount of quality assurance resources required by
application developers, which can sometimes exceed the cost of developing the
application source code. CENTURA TEAM DEVELOPER maximizes the investment dollar
spent to develop and test business logic objects. Using the CENTURA TEAM
DEVELOPER class libraries, application developers can easily share business
logic code between applications. CENTURA TEAM DEVELOPER can deploy a single set
of business logic as either a Windows or a browser client, enabling the
transformation of business applications from Windows clients to Web clients,
without reprogramming the original Windows client logic. Using the built-in
revision control features of CENTURA TEAM DEVELOPER, programming teams have
access to the latest code, making it easier to develop complex applications on
time and on budget. CENTURA TEAM DEVELOPER is well positioned for the emerging
need to develop complex, enterprise-wide component based architecture
applications. Self recovery and self tuning features found in SQLBASE typically
result in fewer support calls from end-users providing better customer
satisfaction between the end user and the application developer.
 
    The Company's products also offer a low total cost of ownership to
end-users. SQLBASE is a very small, yet robust database. This means applications
can run very effectively on a small footprint PC, reducing the hardware cost
required to install and operate applications which embed SQLBASE. SQLBASE
applications can include, within the application, log-in and assignment of
password features for new users, eliminating the need for end-users to know how
to operate the database. With built-in self-tuning and self-recovery processes,
SQLBASE applications automatically reboot and reestablish the database when a PC
loses power. SQLBASE applications reduce the need for internal MIS or data base
administrators, and reduces the amount of support calls for which an end user
would typically pay. End-users do not have to upgrade to 32-bit architectures
before installing applications built with the Company's products. CENTURA NET.DB
operates in a 16-bit browser environment, making it easy to connect end-users
around the world who may not yet have upgraded to a 32-bit PC. Both CENTURA TEAM
DEVELOPER and CENTURA NET.DB make it easy to webify an application built with
CENTURA TEAM DEVELOPER or SQLBASE, allowing access by employees and customers to
corporate data. The Company's products are priced for a PC client/server
environment, minimizing the cost of client/server solutions. This enables a low
cost of entry for small and medium size businesses. The Company's products are
cross platform, enabling applications to operate on Windows NT, Windows 95,
Windows 3.1, DOS and NetWare with minimal programming changes. See "Risk
Factors-- New Product Risks; Rapid Technological Change" and "--Highly
Competitive Markets".
 
    DISTRIBUTION CHANNELS, PARTNERSHIPS AND STRATEGIC ALLIANCES.  The Company
distributes its products using a blended distribution model that provides
incentives for its direct sales force to work closely with business partners.
The Company's Synergy Partner Program is designed to meet the needs of
businesses that include resellers, commercial application developers,
consultants, independent software vendors ("ISVs"), and complementary tools
providers. A number of companies, including SQL Financials, ADP and Aurum have a
partnership with Centura, whereby Centura provides these application developers
the right to remanufacture the SQLBASE product. See "Risk Factors--Dependence
Upon Distribution Channels" and "--Dependence on Third-Party Organizations".
 
    WORLDWIDE MARKETS.  The Company has designed its products and established
its marketing and sales channels to address the worldwide market opportunities,
including markets requiring double-byte enabled source code, for embeddable
databases and PC client/server systems. The Company has established operations
on six continents that have exclusive rights through either wholly-owned
subsidiaries or third-party distribution partners. CENTURA TEAM DEVELOPER is
shipped with OBJECT NATIONALIZER, which facilitates application development in
multiple languages. Approximately 58% of the Company's net revenues for 1997
were derived from sales outside the United States, and its products are
installed in at least 75 countries. The Company generally launches new products
on a worldwide basis. The Company's software
 
                                       7
<PAGE>
products support international data conventions, and certain products have been
localized into French, German and Japanese language editions.
 
    SUPPORT PROGRAMS.  The Company provides product support services directly
and through third-party vendors to enable easy customer implementation of its
client/server systems. The Company provides a variety of programs to support
customers ranging from small development groups to those who require access to
qualified support engineers 24 hours a day, seven days a week. Traditional
service offerings are augmented with an informal support network through a forum
on CompuServe, an Internet news group, and a strong presence on the World Wide
Web. A pay per request program is being implemented, and is scheduled to be
offered beginning in 1998. The Company-certified training partners offer courses
each year to assure customers of the right mix of classroom or on-site training.
Customers can also opt to study at their own pace with a specially developed
computer-based training course. In addition, a team of professional consulting
engineers are available to help companies develop application systems using
Centura products.
 
    CHANGES IN STRATEGIC DIRECTION  On January 6, 1997, in an effort to expand
its product offerings in areas complimentary with the Company's core products,
technology and overall strategic concept and into architectures embracing the
World Wide Web, the Company entered into a definitive agreement to acquire
Infospinner, Inc. ("Infospinner") of Richardson, Texas (the "Merger Agreement").
The Company did not obtain the majority vote of its shareholders required for
approval of the proposed merger within the designated time frame, and as such,
Infospinner elected to exercise its right, pursuant to the Merger Agreement, to
terminate the transaction. Beginning in the second half, and culminating in the
fourth quarter of 1997, the Company refocused and restructured its operations to
leverage its core technological competencies into next generation products which
continue to embrace a distributed architecture with components accessible
through both the client and the server and operating in both the Web and other
thin-clients. With the addition of CENTURA NET.DB, the Company's products now
encompass a comprehensive architecture for the development and deployment of
information systems and applications from a host environment, through two-tier
client/server and SQL databases, to the multi-tier environment of the World Wide
Web. See "Risk Factors--Changes in Strategic Direction: Restructuring;" "--New
Product Risks; Rapid Technological Change".
 
PRODUCTS
 
    The Company's embeddable database, development environments, family of
connectivity products, and Web-based development environments, enable teams of
developers to embed, build and deploy scaleable client/server applications
throughout distributed computing environments. The Company's major products
include:
 
    SQLBASE--THE SQLBASE family consists of embeddable and small-footprint
database products that enable application developers to provide low cost of
ownership applications with complete and robust RDBMS functionality and help
businesses deploy decentralized applications easily and cost-effectively. These
products--SQLBASE SERVER and SQLBASE DESKTOP--help organizations store data on
machines ranging from small mobile devices and single-user PCs to workgroup
servers and company-wide LAN and Web database servers. New versions of SQLBASE,
referred to as the SQLBASE MICROSERVERS, are being designed to meet the needs of
thin-clients and Smart Cards.
 
    CENTURA TEAM DEVELOPER AND SQLWINDOWS--THE CENTURA TEAM DEVELOPER AND
SQLWINDOWS products enable customers to develop and deploy 32- and 16-bit, next
generation and Web-centric client/server object-oriented applications. CENTURA
TEAM DEVELOPER and SQLWINDOWS are created specifically to meet the needs of
application development teams seeking the power to move from workgroup and
enterprise pilot projects into large enterprise applications. These products
deliver client/server application scalability, new Internet integration, and
drag-and-drop replication functionality. The product family includes CENTURA
TEAM DEVELOPER and SQLWINDOWS, CENTURA APPLICATION SERVER, and the CENTURA
DEVELOPERS KIT, a set of

object-oriented interfaces that help developers create reusable objects in the
CENTURA TEAM DEVELOPER 32-bit and SQLWINDOWS 16-bit environments.
 
    CENTURA WEB DEVELOPER--CENTURA WEB DEVELOPER, a subset of CENTURA TEAM
DEVELOPER, enables the development of Web-based, thin-client applications which
allow the deployment of CENTURA TEAM DEVELOPER business logic and transaction
processing applications in thin-client environments.
 
    SQLHOST--THE SQLHOST products allow organizations to integrate DB2 or legacy
data into a client/ server environment without compromising performance, control
or security. SQLHOST for Visual Basic allows Visual Basic applications to access
host-based data.
 
    CENTURA NET.DB--CENTURA NET.DB is a SQL to HTML browser-based Web authoring
tool. CENTURA NET.DB reads the referential integrity of a SQL database, and
automatically generates an HTML page view of each table. Using smart wizards,
Webmasters can easily customize and design dynamic SQL queries and updates of
live databases. The SQL queries can be deployed in any JavaScript enabled
browser and are therefore platform independent. No special browser plug-ins or
server software is needed.

MARKETING, DISTRIBUTION AND PRODUCT SUPPORT
 
    The Company's marketing and sales efforts are targeted to worldwide users
and developers of PC client/server systems and applications. These users,
ranging from individual PC application developers to MIS departments of large
corporations, typically purchase client/server software through different
channels and require different levels of support.
 
                                       10
<PAGE>
    The Company generally segregates its customers, and accordingly its sales
force, into two basic categories:
 
    EMBEDDED APPLICATIONS/LARGE SCALE DEPLOYMENT.  Many customers purchase the
Company's products as part of a larger scale application deployment activity,
such as embedding a database in an application to be sold or otherwise marketed,
or creating an enterprise specific system solution using one or more of the
Company's products. As these applications can be complex and in some cases
critical to the business of an enterprise, these customers typically require a
greater degree of individual attention both from the Company's direct sales
force and technical support organizations, or from technically sophisticated
third parties, than do users who purchase the Company's products for a single
use or one-time development activity. To address the requirements of these
customers, the Company has established a field sales organization, which
operates in the United States, Canada, Mexico, Brazil, France, Germany, Italy,
Switzerland, Austria, the Netherlands, Belgium, the United Kingdom, Australia
and Japan. See "Risk Factors--International Sales and Operations" and "--Recent
Company Losses; Fluctuations in Quarterly Results".
 
    These customers include vertical software partners, hardware original
equipment manufacturers ("OEMs"), systems integrators and ISVs with whom the
Company generally has established marketing or licensing arrangements. Such
partners include Automated Data Processing, Inc (payroll systems), Learmonth and
Burchett Management Systems PLC (CASE tools), Artemis International (project
management), PeopleSoft, Inc. (human resources), Project Software & Development,
Inc. (facilities management), Aurum Software Inc. (sales management) and
Spectrum Associates (manufacturing). In addition, the Company has an
architecture which enables ISVs to use the Company's products to co-engineer
enterprise-wide client/server applications or deliver add-on software. Hardware
OEMs purchase the Company's products and bundle them with their personal
computer hardware or applications software for resale to their customers. The
Company currently has OEM relationships with NCR, IBM, Siemens-Nixdorf, Computer
Associates International, Inc. ("CA") and other computer vendors. The Company
has entered into cooperative arrangements with system integrators, such as
Electronic Data Systems, that build large, custom turnkey solutions for their
corporate customers using the Company's products.
 
    SINGLE USE OR ONE-TIME DEVELOPMENT.  These customers generally utilize
outside services to specify, design, build and deploy limited client/server
systems within the enterprise. In addition, ISVs may utilize the Company's
development tools in the early stages of application development. These
customers include small, medium and large size businesses. The Company reaches
these customers through its corporate telesales organization and through an
indirect distribution channel, consisting of resellers, application developers,
distributors, value-added resellers ("VARs") and consultants.
 
    The Company also distributes its products through major independent
distributors that may in turn sell such products to smaller VARs, resellers and
dealers. The Company presently has a distribution agreement with DistribuPro,
for distribution of the Company's products in North America. The Company also
has a network of international distributors, including Computer 2000 AG GmbH in
Europe and Mitsubishi Corporation in Japan. Many of the Company's distributors
carry competing product lines. The Company's distributors may from time to time
be granted stock exchange or rotation rights. Such returns or exchanges are
generally offset by an immediate replacement order of equal or greater value.
Although the Company believes that, to date, it has provided adequate allowances
for exchanges and returns, there can be no certainty that actual returns will
not exceed the Company's allowances, particularly in connection with
introduction of new products or enhancements. See "Risk Factors--Dependence Upon
Distribution Channels" and "--International Sales and Operations."
 
    In a number of markets, including rapidly growing client/server markets such
as Japan and Korea, the Company has entered into multi-year master distribution
agreements with unrelated companies that have also licensed the use of the
Company's name. These organizations are in place to increase the Company's
opportunities and penetration in such markets where the rapid adoption of
client/server technologies is
 
                                       11
<PAGE>
anticipated. While the Company believes that to date these agreements have
increased the Company's penetration in these markets, there can be no certainty
that this performance will continue or that these relationships will remain in
place. The Company has the option to acquire 100% of the outstanding stock of
one of its foreign distributors, using a purchase price formula based on net
profits and revenues. See "Risk Factors--Dependence Upon Distribution Channels."
 
    The Company also sells its products through a worldwide network of VARs and
consultants that specialize in developing customized solutions for smaller,
departmental networks. These VARs bundle the Company's products and products of
other software vendors into systems that are sold directly to end-users. The
Company has certified over 1,000 VARs marketing to industries such as financial
services, telecommunications, publishing, transportation and health care. See
"Risk Factors--Dependence Upon Distribution Channels."
 
    MARKETING.  To support its sales organizations, the Company conducts
comprehensive marketing programs and cooperative selling arrangements with the
Company's strategic partners. The Company's marketing programs include direct
mail, public relations, advertising, seminars, trade shows and ongoing customer
communication programs. The Company has entered into cooperative selling
arrangements with strategic partners, including NCR, ICL Personal Systems and
Siemens-Nixdorf that provide joint marketing or network solutions for
incorporating their products with the Company's products. The Company also
cooperates with suppliers of competitive client/server software, such as Oracle
Corporation ("Oracle") and Sybase, Inc., ("Sybase"), when customers desire
large-scale, joint solutions that include front-end tools from the Company or
deployment of desktop or mobile database applications.
 
    The majority of the Company's revenues have been derived from the licensing
of software products for PC client/server systems, and such products are
expected to continue to account for substantially all of the Company's revenues
for the foreseeable future. Accordingly, broad market acceptance of PC client/
server systems is critical to the Company's future success. Failure of the
Company to successfully implement its sales and marketing strategies, or the
loss of one or more resellers, distributors, vertical software partners or other
marketing partners, could have a material adverse effect on the Company's
business, operating results and financial condition. See "Risk
Factors--Dependence Upon Distribution Channels" and "--Market Acceptance of PC
Client/Server Systems".
 
    CUSTOMER SUPPORT AND SERVICE.  The Company is committed to providing timely,
high-quality technical support, which the Company believes is critical to
maintaining customer satisfaction in the PC client/server market. Customer
requirements for support and service vary depending on factors such as the
number of different hardware and software vendors involved in an installation,
the complexity of the application and the nature of the hardware configuration.
The Company offers flexible multi-tiered technical support programs tailored to
these specific customer needs. The Company offers a licensed maintenance service
to all its customers to provide bug fixes and software enhancements. In
addition, the Company provides technical support through a telephone hotline
service. For the large enterprise-wide customer, the Company offers
comprehensive premium support programs. The Company broadens its support
coverage through its worldwide network of authorized support centers, certified
business partners and authorized consultants. See "Risk Factors--Dependence on
Third-Party Organizations".
 
RESEARCH, PRODUCT DEVELOPMENT AND ENGINEERING
 
    Since inception, the Company has made substantial investments in research
and product development. During 1997, 1996 and 1995, the Company's expenditures
in research and development, net of capitalized software, were $9.7 million,
$11.0 million and $14.4 million, representing 17%, 17% and 22% of net revenues,
respectively. The Company's products have been developed by its internal product
development staff and, in certain instances, by strategic use of outside
consultants. The Company believes that timely development of new products and
enhancements to existing products is essential to maintain its competitive
position.
 
                                       12
<PAGE>
    The Company is committed to continued development of new technologies for PC
client/server computing. The Company supports major 32-bit operating systems,
including Microsoft Windows 95, Microsoft Windows NT and Novell NetWare. In
addition, the Company plans to continue to offer upgrades to its products.
Delays or difficulties associated with new products or product enhancements
could have a material adverse effect on the Company's business, operating
results and financial condition. See "Risk Factors--New Product Risks; Rapid
Technological Change" and "--Component Software Markets".
 
COMPETITION
 
    The market for embedded databases and application development tools system
software is intensely competitive and rapidly changing. The Company's products
are specifically targeted at the emerging portion of this market relating to
embeddable database PC and Web client/server software, and the Company's current
and prospective competitors offer a variety of solutions to address this market
segment.
 
    EMBEDDABLE DATABASE MARKET.  As database capacity is often indicative of
differences in customer application, segments within the PC client/server market
in which the Company competes can generally be distinguished and segregated by
the number of anticipated users and target capacity of the database utilized.
The Company generally markets its database products in environments utilizing
capacity ranging from small, five kilobyte Smart Card environments to those in
excess of five Gigabytes. Competitors of the Company include Microsoft, Oracle,
Computer Associates, IBM, Sybase, Pervasive, and Informix, and generally have
product offerings which compete with the Company's products in some or all of
these capacity ranges. In addition, some of these competitors are providers of
sophisticated database software, originally designed and marketed primarily for
use with mainframes and minicomputers, which, if successfully re-configured to
provide similar functionality in PC client/server, or smaller capacity
environments, could materially and adversely impact the Company's revenues,
results of operations and financial condition.
 
    TOOLS AND CONNECTIVITY MARKETS.  The Company faces competition from
providers of application development software, such as Sybase's Powersoft
Division, Microsoft, and Borland, and connectivity software competitors such as
IBM. The Company also faces potential competition from vendors of applications
development tools based on 4GLs (fourth-generation languages) or CASE (Computer
Aided Software Engineers) technologies. With the emergence of the World Wide Web
as an important platform for application development and deployment, additional
competitors or potential competitors have emerged.
 
    Many of the Company's competitors have longer operating histories and
significantly greater financial, technical, sales, marketing and other
resources, as well as greater name recognition and a larger installed base, than
the Company. In addition, many competitors have established relationships with
customers of the Company. The Company's competitors could in the future
introduce products with more features and lower prices than the Company's
offerings. These companies could also bundle existing or new products with more
established products to compete with the Company. Furthermore, as the PC and Web
client/ server market expands, a number of companies, with significantly greater
resources than the Company, could attempt to increase their presence in this
market by acquiring or forming strategic alliances with competitors of the
Company, or by introducing products specifically designed for the PC and Web
client/ server market.
 
    The principal competitive factors affecting the market for the Company's
products include breadth of distribution and name recognition, product
architecture, performance, functionality, price, product quality, customer
support, and the Company's financial viability. The Company experienced
increased competition during 1997, 1996, and 1995, resulting in loss of market
share. The Company must continue to introduce enhancements to its existing
products and offer new products on a timely basis in order to remain
competitive. However, even if the Company introduces such products in this
manner, it may not be able to
 
                                       13
<PAGE>
compete effectively because of the significantly larger resources available to
many of the Company's competitors. There can be no assurance that the Company
will be able to compete successfully or that competition will not have a
material adverse effect on the Company's business, operating results and
financial condition. See "Risk Factors--Highly Competitive Markets" and
"--Market Acceptance of PC Client/Server Systems".
 
INTELLECTUAL PROPERTY
 
    The Company currently has one patent issued with respect to its SQLWINDOWS
and CENTURA TEAM DEVELOPER products and relies on a combination of trademark,
copyright and trade secret protection and nondisclosure agreements to establish
and protect its proprietary rights. Policing unauthorized use of the Company's
technology is expensive and difficult, and there can be no assurance that these
measures will be successful. While the Company's competitive position may be
affected by its ability to protect its proprietary information, the Company
believes that ultimately factors such as the technical expertise and innovative
skill of its personnel, its name recognition, and ongoing product support and
enhancements may be more significant in maintaining the Company's competitive
position.
 
    The Company provides its software products to customers under non-exclusive,
non-transferable license agreements. As is customary in the software industry to
protect intellectual property rights, the Company does not sell or transfer
title to its software products to customers. Under the Company's current
standard form of end user license agreement, licensed software may be used
solely for the customer's internal operations and, except for limited deployment
rights provided in certain of its SQLWINDOWS packages, only on designated
computers at specified sites. The Company relies primarily on "shrink-wrap"
licenses for the protection of products intended for single, one-time use or
limited deployment. A shrink-wrap license agreement is a printed license
agreement included within packaged software that sets forth the terms and
conditions under which the purchaser can use the product, and binds the
purchaser by its acceptance and purchase of the software products to such terms
and conditions. Shrink-wrap licenses typically are not signed by the licensee
and therefore may be unenforceable under the laws of certain jurisdictions.
 
    The Company has entered into source code escrow agreements with a number of
resellers and end users that require release of source code to such parties with
a limited, nonexclusive right to use such code in the event that there is a
bankruptcy proceeding by or against the Company, the Company ceases to do
business or the Company breaches its contractual obligations to the customer.
The Company has, in certain cases, licensed its source code to customers for
specific uses.
 
    There can be no assurance that third parties will not assert infringement
claims against the Company in the future with respect to current or future
products or that any such assertion may not result in costly litigation or
require the Company to obtain a license to intellectual property rights of third
parties. There can be no assurance that such licenses will be available on
reasonable terms, or at all. As the number of software products in the industry
increases and the functionality of these products further overlap, 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.
 
EMPLOYEES
 
    As of December 31, 1997, the Company had 180 full-time employees, including
31 in research and development, 6 in manufacturing, 94 in sales and marketing,
16 in technical services and support and 33 in finance and administration. The
Company maintains competitive compensation, benefits, equity participation and
work environment policies to assist in attracting and retaining qualified
personnel. None of the Company's employees are covered by collective bargaining
agreements. The Company believes its relationship with its employees is good.
The Company believes that the success of its business will depend in large
 
                                       14
<PAGE>
part on its ability to attract and retain qualified personnel. Competition for
such personnel is intense, and there can be no assurance that the Company will
be successful in attracting and retaining such personnel.
 
RISK FACTORS
 
    This Annual Report on Form 10-K contains certain forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934. Actual results could differ materially
from those projected in the forward-looking statements as a result of certain of
the risk factors set forth below and elsewhere in this Annual Report on Form
10-K. In evaluating the Company's business, prospective investors should
carefully consider the following factors in addition to the other information
presented in this report.
 
    CHANGES IN STRATEGIC DIRECTION: RESTRUCTURING.  In efforts to stem losses
and maximize return on the Company's core assets and technologies, the Company
has restructured its operations and announced changes in strategic direction
several times in recent financial periods. The first of these changes, which
began in December 1995, encompassed a change in the Company's name from Gupta
Corporation to Centura Software Corporation and the identification of a flagship
product bearing the name CENTURA. In early 1997, the Company refocused its
marketing and sales efforts away from RDBMS and development tools products to a
middleware connectivity product and the related Merger Agreement with
Infospinner for which the Company did not obtain required shareholder approval
within the specified time frame and, as such, was not consummated. In the second
half of 1997, however, the Company restructured and refocused operations on its
core competencies, products and technologies and terminated its distribution
arrangement with Infospinner. There can be no assurance that the restructuring
efforts the Company has engaged in to date will be successful or that the
Company will be able to sustain profitability on a quarterly or annual basis. In
addition, there can be no assurance that the Company's management will not deem
it appropriate to undertake other major restructuring efforts or changes in
strategic direction in the future or to what degree any of these efforts will
result in improved operational performance, if at all.
 
    RECENT CHANGES IN SENIOR MANAGEMENT.  In the fourth quarter of 1997, the
Company announced significant changes in senior management. Such changes
included the appointment of Scott R. Broomfield as Chief Executive Officer, John
W. Bowman as Chief Financial Officer, and Kathy Lane as Senior Vice President of
Marketing, and the election of Messrs. Jack King, Phillip Koen, Jr., and Earl
Stahl to the Company's Board of Directors, and the retirement of Samuel M.
Inman, III, Earl Stahl and Richard Gelhaus from their positions as officers of
the Company. In February 1998 the Company announced the election of Messrs.
William D. Nicholas and Peter Micciche to the Board of Directors and the
appointment of Scott R. Broomfield to the position of Chairman & CEO. There can
be no assurance that the new management team will be successful in execution of
its objectives or that the successful execution of these objectives will result
in improved operating results or financial position of the Company.
 
    DEPENDENCE ON KEY PERSONNEL.  The Company's future performance is
substantially dependent on the performance of its executive officers and key
product development, technical, sales, marketing and management personnel. The
Company does not have employment or non-competition agreements with any of its
employees. The loss of the services of any executive officer or other key
technical or management personnel of the Company for any reason could have a
material adverse effect on the business, operating results and financial
condition of the Company. In addition, the Company needs to recruit a Vice
President, Engineering/Chief Technology Officer. The Company considers this
position critical to the success of its ongoing competitive position in defined
markets and operations. There can be no assurance that an appropriate individual
will be located to fill this position on a timely basis on terms reasonable to
the Company, or at all.
 
    The future success of the Company also depends on its continuing ability to
identify, hire, train, motivate and retain other highly qualified technical and
managerial personnel. Competition for such personnel is intense and the Company
has experienced difficulty in identifying and hiring qualified
 
                                       15
<PAGE>
engineering and software development personnel. There can be no assurance that
the Company will be able to attract, assimilate or retain other highly qualified
technical and managerial personnel in the future. The inability to attract and
retain the necessary technical and managerial personnel could have a material
and adverse effect upon its business, operating results and financial condition.
See "Business--Employees" and "--Executive Officers of Registrant".
 
    RECENT COMPANY LOSSES; FLUCTUATIONS IN QUARTERLY RESULTS.  The Company has
experienced in the past and may in the future to continue to experience
significant fluctuations in quarterly operating results. The Company reported a
loss of $0.6 million for fiscal year 1997, a profit of $2.0 million for 1996,
and a loss of $44.1 million for 1995. There can be no assurance that the
restructuring efforts the Company has engaged in to date will be successful or
that the Company will be able to sustain profitability on a quarterly or annual
basis. Many of the Company's product licensing arrangements are subject to
revenue recognition on a per-unit deployed basis as the Company's deferred
obligation to such customers is gradually extinguished. Revenue recognition in
such cases is therefore dependent upon the business activities of the Company's
customers and the timely and accurate reporting of such activities to the
Company, which makes predictability of the related revenue extremely uncertain.
In addition, quarterly operating results of the Company will depend on a number
of other factors that are difficult to forecast, including, general market
demand for the Company's products; the size and timing of individual orders
during a quarter; the Company's ability to fulfill such orders; introduction,
localization or enhancement of products by the Company; delays in the
introduction and/or enhancement of products by the Company and its competitors;
market acceptance of new products; reviews in the industry press concerning the
products of the Company or its competitors; software "bugs" or other product
quality problems; competition and pricing in the software industry; sales mix
among distribution channels; customer order deferrals in anticipation of new
products; reduction in demand for existing products and shortening of product
life cycles as a result of new product introductions; changes in operating
expenses; changes in the Company's strategy; personnel changes; foreign currency
exchange rates; mix of products sold; inventory obsolescence; product returns
and rotations; and general economic conditions. Sales of the Company's products
also may be negatively affected by delays in the introduction or availability of
new hardware and software products from third parties. The Company's financial
results also may vary as a result of seasonal factors including year and quarter
end purchasing and the timing of marketing activities, such as industry
conventions and tradeshows.
 
    Although the Company has operated historically with little or no backlog of
traditional boxed product shipments, it has experienced a seasonal pattern of
product revenue decline between the fourth quarter and the succeeding first
quarter, contributing to lower worldwide product revenues and operating results
during such quarters. It has generally realized lower European product revenues
in the third quarter as compared to the rest of the year. The Company has also
experienced a pattern of recording a substantial portion of its revenues in the
third month of a quarter. As a result, product revenues in any quarter are
dependent on orders booked in the last month. Because the Company's staffing and
other operating expenses are based in part on anticipated net revenues, a
substantial portion of which may not be generated until the end of each quarter,
delays in the receipt or shipment of orders, including delays that may be
occasioned by failures of third party product fulfillment firms to produce and
ship products, or the actual loss of product orders can cause significant
variations in operating results from quarter to quarter. The Company may be
unable to adjust spending in a timely manner to compensate for any unexpected
revenue shortfall. Accordingly, any significant shortfall in sales of the
Company's products in relation to the Company's expectations could have an
immediate adverse impact on the Company's business, operating results and
financial condition. To the extent that the Company's expenses exceed expected
revenues in any fiscal period, its business, operating results and financial
condition could be materially and adversely affected. Due to the foregoing
factors, it is likely that the Company's operating results may, during any
fiscal period, fall below the expectations of securities analysts and investors.
In such event, the trading price of the Company's common stock could be
materially and adversely affected. See "Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operations".
 
                                       16
<PAGE>
    VOLATILITY OF THE COMPANY'S COMMON STOCK PRICE.  The market for the
Company's common stock is highly volatile. The trading price of the Company's
common stock fluctuated significantly in 1997, 1996 and 1995, and may continue
to be subject to wide fluctuations in response to quarterly variations in
operating and financial results, announcements of new products or customer
contracts by the Company or its competitors, litigation and other factors. Any
shortfall in revenue or earnings from levels expected by securities analysts or
others could have an immediate and significant adverse effect on the trading
price of the Company's common stock in any given period. Additionally, the
Company may not learn of, or be able to confirm, revenue or earnings shortfalls
until late in the fiscal quarter or following the end of the quarter, which
could result in an even more immediate and adverse effect on the trading of the
Company's common stock. Finally, the Company participates in a highly dynamic
industry, which often results in significant volatility of its common stock
price.
 
    DILUTIVE AND POTENTIAL DILUTIVE EFFECT TO SHAREHOLDERS.  The Company has
engaged in a number of transactions which have resulted in dilution to the
Company's shareholders. On May 2, 1994, a lawsuit was filed against the Company
and certain of its officers and directors by a holder of the Company's common
stock, on his own behalf and purportedly on behalf of a class of others
similarly situated (the "Class Action Lawsuit"). The Company reached a binding
settlement agreement (the "Settlement Agreement") with plaintiffs' counsel in
the lawsuit, and gained court approval of the Settlement Agreement on September
30, 1996. As part of the settlement, the Company agreed to provide up to a
maximum of 2,500,000 shares of its common stock (the "Settlement Shares") to a
fund to be distributed among the members of the plaintiff class. As of December
31, 1997, 2,500,000 Settlement Shares have been issued and distributed in full
settlement of the Class Action Lawsuit. Issuance of the Settlement Shares was
exempt from the registration requirements of Section 5 of the Securities Act of
1933, as amended (the "Securities Act"), pursuant to Section 3(a)(10) of the
Securities Act, which provides for exemption of registration under the
Securities Act for securities issued pursuant to terms and conditions which have
been approved, after a hearing on the fairness of such terms and conditions, by
a United States court. As a result, the Settlement Shares, when issued and
delivered in accordance with the Settlement Agreement approved by the United
States District Court for the Northern District of California, were fully
tradeable, fully paid and non-assessable. See Note 6 of Notes to Consolidated
Financial Statements.
 
    In February 1998, Computer Associates, Inc. ("CA"), and Newport Acquisition
Company, LLP ("NAC") entered into a Note Purchase and Sale Agreement (to which
the Company consented) and the Company and NAC entered into a Note Conversion
Agreement (the "Agreements"). Under the terms of the Agreements, a promissory
note, plus accrued interest, in the amount of $12,251,000, payable to CA (the
"CA Note") was acquired by NAC, and immediately converted into 11,415,094 shares
of the Company's common stock (the "Shares"). Concurrently with execution of the
Agreements, the Company and NAC entered into an Investor Rights Agreement (the
"Rights Agreement") wherein the Company has agreed to register the Shares under
the Securities Act, effective February 27, 1999.
 
    Also in February 1998, pursuant to the terms a Common of Stock and Warrant
Purchase Agreement, the Company completed a management-led private placement of
2,330,191 shares of the Company's common stock (the "Private Placement"),
resulting in gross proceeds to the Company of $2,470,000. Transaction costs
associated with both the Agreements and the Private Placement are estimated to
be approximately $600,000. The Company has agreed to register the Private
Placement shares under the Securities Act.
 
    In June 1997, the Company issued warrants to purchase 90,000 and 10,000
shares of common stock to Pacific Business Funding Corporation and its affiliate
Sand Hill Capital, LLC, respectively, at an exercise price of $2.094 per share.
The warrants expire on June 30, 2002. In February 1998, in connection with the
Agreements, the Company entered into a Warrant Purchase Agreement with CA
wherein the Company issued and sold to CA, a warrant to purchase 500,000 shares
of the Company's common stock (the "CA Warrant"). The CA Warrant is exercisable
at $1.906 per share and expires on February 27, 2003. The Company has agreed to
register the shares issuable upon exercise of the CA Warrant under the
Securities
 
                                       17
<PAGE>
Act, no later than April 29, 1998. Also in February 1998, in connection with the
Private Placement the Company issued warrants to purchase 582,548 shares of the
Company's common stock at an exercise price of $1.25 per share (the "Private
Placement Warrants"). The Private Placement Warrants expire on February 27,
2003. Also, in consideration of services rendered in connection with the Private
Placement, the Company issued to Rochon Capital Group, Ltd. warrants to purchase
354,717 shaes of the Company's common stock at an exercise price of $2.12 (the
"Rochon Warrants"). The Rochon Warrants expire on February 27, 2003. The Company
has agreed to register the shares issuable under the terms of the Private
Placement Warrants and the Rochon Warrants under the Securities Act. In March
1998 the Company issued to NAC an additional warrant to purchase 893,320 shares
of the Company's Common Stock at an exercise price of $1.81 per share (the "NAC
Warrant"), pursuant to a Right of First Refusal provision contained in the
Rights Agreement. The NAC Warrant is subject to three-year vesting.
 
    From time to time, the Company issues shares of common stock pursuant to its
1992 Employee Stock Purchase Plan and pursuant to options granted under its 1995
Incentive Stock Option Plan, 1998 Employee Stock Option Plan and 1996 Directors'
Stock Option Plan. Additional options remain outstanding and are exercisable
pursuant to the Company's 1986 Incentive Stock Option Plan, which terminated in
July 1996. In addition, the Company has issued non-plan options to purchase an
aggregate of 1,500,000 shares of common stock to the Company's Chief Executive
Officer, Chief Financial Officer and Sr. Vice President of Marketing. In March
1998, the Company's Board of Directors approved the 1998 Employee Stock Option
Plan, under which options to purchase 1,415,000 shares of common stock are
issuable to non-officer employees.
 
    Future issuance of such shares of the Company's common stock pursuant to any
of the foregoing will dilute the beneficial ownership of existing Company
shareholders.
 
    NEED FOR ADDITIONAL EQUITY FINANCING.  The Company may be required to seek
additional equity financing to finance the acquisition of new products and
technologies, capital equipment and continuing operations. If the Company needs
further financing, there can be no assurance that it will be available on
reasonable terms or at all. Any additional equity financing will result in
dilution to the Company's shareholders.
 
    NEW PRODUCT RISKS; RAPID TECHNOLOGICAL CHANGE.  The markets for the
Company's software products and services are characterized by rapid
technological developments, evolving industry standards, swift changes in
customer requirements and computer operating environments, and frequent new
product introductions and enhancements. As a result, the success of the Company
depends substantially upon its ability to continue to enhance existing products,
develop and introduce in a timely manner, new products incorporating
technological advances and meet increasing customer expectations, all on a
timely and cost-effective basis. To the extent one or more competitors introduce
products that better address customer needs, the Company's businesses could be
adversely affected. The Company's success will also depend on the ability of its
primary products, SQLBASE, CENTURA TEAM DEVELOPER, SQLWINDOWS, CENTURA NET.DB,
and SQLHOST, to perform well with existing and future leading, industry-standard
application software products intended to be used in connection with RDBMS. Any
failure to deliver these products as scheduled or their failure to achieve early
market acceptance as a result of competition, technological change, failure of
the Company to timely release new versions or upgrades, failure of such upgrades
to achieve market acceptance or otherwise, could have a material adverse effect
on the business, operating results and financial condition of the Company. In
addition, commercial acceptance of the Company's products and services could be
adversely affected by critical or negative statements or reports by industry and
financial analysts concerning the Company and its products, or other factors
such as the Company's financial performance. If the Company is unable to develop
and introduce new products or enhancements to existing products in a timely
manner in response to changing market conditions or customer requirements, its
business, operating results and financial condition could be materially and
adversely affected.
 
                                       18
<PAGE>
    The Company depends substantially upon internal efforts for the development
of new products and product enhancements. The Company has in the past
experienced delays in the development of new products and product versions,
which resulted in loss or delays of product revenues, and there can be no
assurance that the Company will not experience further delays in connection with
its current product development or future development activities. Also, software
products as complex as those offered by the Company may contain undetected
errors when first introduced or as new versions are released. The Company has in
the past discovered software errors in certain of its new products and
enhancements, respectively, after their introduction. Although the Company has
not experienced material adverse effects resulting from any such errors to date,
there can be no assurance that errors will not be found in new products or
releases after commencement of commercial shipments, resulting in adverse
product reviews and a loss of or delay in market acceptance, which could have a
material adverse effect upon the Company's business, operating results and
financial condition.
 
    From time to time, the Company or its competitors may announce new products,
product versions, capabilities or technologies that have the potential to
replace or shorten the life cycles of the Company's existing products. The
Company has historically experienced increased returns of a particular product
version following the announcement of a planned release of a new version of that
product. The Company provides allowances for anticipated returns, and believes
its existing policies result in the establishment of allowances that are
adequate, and have been adequate in the past, but there can be no assurance that
product returns will not exceed such allowances in the future. The announcement
of currently planned or other new products may cause customers to delay their
purchasing decisions in anticipation of such products, which could have a
material adverse effect on business, operating results and financial condition
of the Company. See "Business--Research and Product Development" and "Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations".
 
    YEAR 2000 ISSUE.  The "Year 2000 Issue" arises because most computer systems
and programs were designed to handle only a two-digit year, as opposed to a four
digit year. When the year 2000 begins these computers may interpret "00" as the
year 1900 and could either stop processing date-related computations or could
process them incorrectly. As customers and potential customers of the Company
begin to devote incremental resources to this issue, resources previously
allocated to other information systems requirements may be redirected to address
the Year 2000 issue. To the extent that the Company's products are not selected
as part of customers' overall Year 2000 solution, redirection of these customer
resources could have a material adverse effect on the Company's results of
operations and financial condition. In addition, the Year 2000 Issue creates
risk for the Company from unforeseen problems in its internal computer systems
and from third parties with which the Company interacts. Such failures of the
Company's and/or third parties' computer systems could have a material impact on
the Company's ability to conduct its business, and to process and account for
the transfer of funds electronically.
 
    EMBEDDABLE DATABASE MARKET.  Since database capacity is often indicative of
differences in customer application, segments within the PC client/server market
in which the Company competes can generally be distinguished and segregated by
the target capacity of the database utilized. The Company generally markets its
database products in environments utilizing capacity ranging from small, five
kilobyte Smart Card environments to those in excess of five Gigabytes.
Competitors of the Company, including Microsoft, Oracle, CA, IBM, Sybase,
Borland, Pervasive, and Informix, generally have product offerings which compete
with the Company's products in some or all of these capacity ranges. In
addition, some of these competitors are providers of sophisticated database
software, originally designed and marketed primarily for use with mainframes and
minicomputers, which, if successfully re-configured to provide similar
functionality in Windows or Browser clients, or smaller capacity environments,
could materially and adversely impact the Company's revenues, results of
operations and financial condition.
 
    COMPETITION.  The market for embedded databases and application development
tools system software is intensely competitive and rapidly changing. The
Company's products are specifically targeted at
 
                                       19
<PAGE>
the emerging portion of this market relating to embeddable PC and Web
client/server software, and the Company's current and prospective competitors
offer a variety of solutions to address this market segment. The Company faces
competition from providers of application development software, such as Oracle,
Sybase's Powersoft Division, Microsoft, and Borland, and connectivity software
competitors such as IBM. The Company also faces potential competition from
vendors of applications development tools based on 4GLs (generation languages)
or CASE (Computer Aided Software Engineers) technologies. With the emergence of
the World Wide Web as an important platform for application development and
deployment and a variety of newly created Java based development tools,
additional competitors or potential competitors have emerged.
 
    Many of the Company's competitors have longer operating histories and
significantly greater financial, technical, sales, marketing and other
resources, as well as greater name recognition and a larger installed base, than
the Company. In addition, many competitors have established relationships with
customers of the Company. The Company's competitors could in the future
introduce products with more features and lower prices than the Company's
offerings. These companies could also bundle existing or new products with more
established products to compete with the Company. Furthermore, as the PC and Web
client/ server market expands, a number of companies, with significantly greater
resources than the Company, could attempt to increase their presence in this
market by acquiring or forming strategic alliances with competitors of the
Company, or by introducing products specifically designed for the PC and Web
client/ server market.
 
    The principal competitive factors affecting the market for the Company's
products include breadth of distribution and name recognition, product
architecture, performance, functionality, price, product quality, customer
support. The Company experienced increased competition during 1997, 1996, and
1995, resulting in loss of market share. The Company must continue to introduce
enhancements to its existing products and offer new products on a timely basis
in order to remain competitive. However, even if the Company introduces such
products in this manner, it may not be able to compete effectively because of
the significantly larger resources available to many of the Company's
competitors. There can be no assurance that the Company will be able to compete
successfully or that competition will not have a material adverse effect on the
Company's business, operating results and financial condition. See
"Business--Competition".
 
    MARKET ACCEPTANCE OF PC CLIENT/SERVER SYSTEMS.  To date, substantially all
of the Company's revenues have been derived from the licensing of software
products for PC client/server systems and licensing of such products is expected
to continue to account for substantially all of the Company's revenues for the
foreseeable future. With the increasing focus on enterprise-wide systems that
embrace the World Wide Web, some customers may opt for solutions that favor
mainframe or mini-computer solutions with associated Web connectivity.
Accordingly, some companies may abandon use of PC client/server systems, which
could have a material adverse effect on the Company's future success. See "Item
7. Management's Discussion and Analysis of Financial Condition and Results of
Operations".
 
    COMPONENT SOFTWARE MARKETS.  The advent of so-called "component" software
may alter the way in which customers buy software. In this structure, logical
statements or discreet "units of activity" can be distributed pursuant to
executable statements within a Windows or Browser client environment. As
specific software functionality can be bundled into smaller units or objects
rather than in broad, highly functional products such as the Company's
development tools, customers may be less willing to buy such broad, highly
functional products. If such a trend continues, the Company may choose to
introduce component-type products. The costs and efforts necessary to package
and distribute such components are largely unknown and there can be no assurance
that the Company will be able to repackage and distribute its products in such a
component-type software structure, in an efficient manner, or at all.
 
    INTERNET SOFTWARE MARKET.  The market for Internet software in general, and
the segments of such market addressed by the Company's products in particular,
are relatively new. The future financial performance of the Company will depend
in part on the continued expansion of this market and these
 
                                       20
<PAGE>
market segments and the growth in the demand for other products developed by the
Company, as well as increased acceptance of the Company's products by MIS
professionals. There can be no assurance that the Internet software market and
the relevant segments of the market will continue to grow, that the Company will
be able to respond effectively to the evolving requirements of the market and
market segments, or that MIS professionals will accept the Company's products.
If the Company is not successful in developing, marketing, localizing and
selling applications that gain commercial acceptance in these markets and market
segments on a timely basis, the Company's business, operating results and
financial condition could be materially and adversely affected. See
"Business--Overview".
 
    DEPENDENCE UPON DISTRIBUTION CHANNELS.  The Company relies on relationships
with value-added resellers and independent third party distributors for a
substantial portion of its sales and revenues. Some of the Company's resellers
and distributors also offer competing products. Most of the Company's resellers
and distributors are not subject to any minimum purchase requirements, they can
cease marketing the Company's products at any time, and they may from time to
time be granted stock exchange or rotation rights. Moreover, the introduction of
new and enhanced products may result in higher product returns and exchanges
from distributors and resellers. Any product returns or exchanges in excess of
recorded allowances could have a material adverse effect on the Company's
business, operating results and financial condition. The Company also maintains
strategic relationships with a number of vertical software vendors and other
technology companies for marketing or resale of the Company's products. Any
termination or significant disruption of the Company's relationship with any of
its resellers or distributors, or the failure by such parties to renew
agreements with the Company, could materially and adversely affect the Company's
business, operating results and financial condition. Since 1994 the Company has
reduced its resources devoted to North American corporate sales and also
decreased its expenditures on corporate and product marketing. Failure of the
Company to successfully implement, support and manage its sales strategies could
have a material adverse effect on the Company.
 
    The distribution channels through which client/server software products are
sold have been characterized by rapid change, including consolidations and
financial difficulties of distributors, resellers and other marketing partners
including certain of the Company's current distributors. The bankruptcy,
deterioration in financial condition or other business difficulties of a
distributor or retailer could render the Company's accounts receivable from such
entity uncollectible, and this could result in a material adverse effect on the
Company's business, operating results and financial condition. There can be no
assurance that distributors will continue to purchase the Company's products or
provide the Company's products with adequate promotional support. Failure of
distributors to do so could have a material and adverse effect on the Company's
business, operating results and financial condition.
 
    In a number of international markets the Company has entered into
quasi-exclusive, multi-year agreements with independent companies that have also
licensed the use of the Company's name. These agreements are in place to
increase the Company's opportunities and penetration in such markets where the
rapid adoption of client/server technologies is anticipated. While the Company
believes that to date these agreements have increased the Company's penetration
in such markets, there can be no certainty that this performance will continue
nor that these relationships will remain in place. The Company's future cost of
maintaining its business in these markets could increase substantially if these
agreements are not renewed. See "Business--Marketing, Distribution and Product
Support".
 
    DEPENDENCE ON THIRD-PARTY ORGANIZATIONS.  The Company is increasingly
dependent on the efforts of third party "partners", including consultants,
system houses and software developers to implement, service and support the
Company's products. These third parties increasingly have opportunities to
select from a very broad range of products from the Company's competitors, many
of whom have greater resources and market acceptance than the Company. In order
to succeed, the Company must actively recruit and sustain relationships with
these third parties. There can be no assurance that the Company will be
successful in recruiting new partners or in sustaining its relationships with
its existing partners.
 
                                       21
<PAGE>
    INTERNATIONAL SALES AND OPERATIONS.  International sales represented 58%,
60% and 61% of the Company's net revenues for the years ended December 31, 1997,
1996 and 1995, respectively. A key component of the Company's strategy is
continued expansion into international markets, and the Company currently
anticipates that international sales, particularly in new and emerging markets,
will continue to account for a significant percentage of total revenues. The
Company will need to retain effective distributors, and hire, retain and
motivate qualified personnel internationally to maintain and/or expand its
international presence. There can be no assurance that the Company will be able
to successfully market, sell, localize and deliver its products in these
international markets. In addition to the uncertainty as to the Company's
ability to sustain or expand its international presence, there are certain risks
inherent in doing business on an international level, such as unexpected changes
in regulatory requirements and government controls, problems and delays in
collecting accounts receivable, tariffs, export license requirements and other
trade barriers, difficulties in staffing and managing foreign operations, longer
payment cycles, political and economic instability, fluctuations in currency
exchange rates, seasonal reductions in business activity during summer months in
Europe and certain other parts of the world, restrictions on the export of
critical technology, and potentially adverse tax consequences, which could
adversely impact the success of international operations. Sales of the Company's
products are denominated both in local currencies of the respective geographic
region and in US dollars, depending upon the economic stability of that region
and locally accepted business practices. Accordingly, any increase in the value
of the US dollar relative to local currencies in these markets may negatively
impact revenues, results of operations and financial condition. An increase in
the relative value of the US dollar would serve to increase the relative foreign
currency cost to the customer of a US dollar denominated purchase, which may
negatively affect the Company's sales in foreign markets. In addition, the US
dollar value of a sale denominated in a region's local currency decreases in
proportion to relative increases in the value of the US dollar. In addition,
effective copyright and trade secret protection may be limited or unavailable
under the laws of certain foreign jurisdictions. There can be no assurance that
one or more of such factors will not have a material adverse effect on the
Company's international operations and, consequently, on the Company's business,
operating results and financial condition. See "Business--Marketing,
Distribution and Product Support--Customer Support and Service".
 
    PROPRIETARY RIGHTS.  The success and ability of the Company to compete is
dependent in part upon the Company's proprietary technology. While the Company
relies on trademark, trade secret and copyright laws to protect its technology,
the Company believes that factors such as the technological and creative skills
of its personnel, new product developments, frequent product enhancements, name
recognition and customer support are more essential to establishing and
maintaining a technology leadership position. The Company has one patent with
respect to its SQLWINDOWS and CENTURA TEAM DEVELOPER products. The Company
believes that the ownership of patents is not presently a significant factor in
its business and that its success does not depend on the ownership of patents,
but primarily on the innovative skills, technical competence and marketing
abilities of its personnel. Also, there can be no assurance that others will not
develop technologies that are similar or superior to the Company's technology.
The source code for the Company's proprietary software is protected both as a
trade secret and as a copyrighted work. Despite these precautions, it may be
possible for a third party to copy or otherwise obtain and use their products or
technology without authorization, or to develop similar technology
independently. In addition, effective copyright and trade secret protection may
be unavailable or limited in certain foreign countries.
 
    The Company generally enters into confidentiality or license agreements with
its employees, consultants and vendors, and generally controls access to and
distribution of its software, documentation and other proprietary information.
Despite efforts to protect proprietary rights, unauthorized parties may attempt
to copy aspects of the Company's products or to obtain and use information that
is regarded as proprietary. Policing such unauthorized use is difficult. There
can be no assurance that the steps taken by the Company will prevent
misappropriation of the Company's technology or that such agreements will be
enforceable. In addition, litigation may be necessary in the future to enforce
intellectual property rights, to protect trade secrets or to determine the
validity and scope of the proprietary rights of others. Such
 
                                       22
<PAGE>
litigation could result in substantial costs and diversion of resources and
could have a material adverse effect on the Company's business, operating
results and financial condition.
 
    There can be no assurance that third parties will not claim infringement by
the Company with respect to current or future products, and the Company expects
that it will increasingly be subject to such claims as the number of products
and competitors in the client/server and Internet connectivity software market
grows and the functionality of such products overlaps with other industry
segments. In the past, the Company has received notices alleging that its
products infringe trademarks of third parties. The Company has historically
dealt with and will in the future continue to deal with such claims in the
ordinary course of business, evaluating the merits of each claim on an
individual basis. There are currently no material pending legal proceedings
against the Company regarding trademark infringement. Any such third party
claims, whether or not they are meritorious, could result in costly litigation
or require the Company to enter into royalty or licensing agreements. Such
royalty or license agreements, if required, may not be available on terms
acceptable to the Company, or at all. If the Company was found to have infringed
upon the proprietary rights of third parties, it could be required to pay
damages, cease sales of the infringing products and redesign or discontinue such
products, any of which could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business--Intellectual
Property".
 
    MANAGEMENT OF POTENTIAL GROWTH.  In recent years, the Company has
experienced both expansion and contraction of its operations each of which has
placed significant demands on the Company's administrative, operational and
financial resources. To manage future growth, if any, the Company must continue
to improve its financial and management controls, reporting systems and
procedures on a timely basis and expand, train and manage its work force. There
can be no assurance that the Company will be able to perform such actions
successfully. The Company intends to continue to invest in improving its
financial systems and controls in connection with higher levels of operations.
Although the Company believes that its systems and controls are adequate for the
current level of operations, the Company anticipates that it may need to add
additional personnel and expand and upgrade its financial systems to manage any
future growth. The Company's failure to do so could have a material adverse
effect upon the Company's business, operating results and financial condition.
 
    LEGAL PROCEEDINGS.  On September 17, 1997, Technology Venture (Software)
Holdings Limited, formerly known as Eagerquest Investments Limited
("Eagerquest") filed suit against the Company in the United States District
Court for the Central District of California alleging that the Company acted
improperly in terminating its contract with Eagerquest for the distribution of
the Company's products in the territories of Hong Kong and China and that the
Company's actions illegally damaged Eagerquest. The Company believes that its
actions were within its rights under its contract with Eagerquest and that the
allegations are without merit. The Company intends to defend itself vigorously
in this action and that the outcome will not have a material adverse affect on
the Company's financial situation or business prospects.
 
    Other than the above, there are currently no material pending legal
proceedings against the Company or any of its subsidiaries. The Company operates
in an environment, however, where litigation may occur in the course of its
normal business operations. In the complex and volatile industry in which the
Company operates, disputes, litigation, regulatory proceedings and other actions
are a necessary risk of doing business. There can be no assurance that the
Company will not participate in such legal proceedings and that the costs and
charges will not have a material adverse impact on the Company's future success.

OVERVIEW
 
    The Company commenced operations in 1984 and provides a suite of products
application developers use to build and deploy business applications in a cost
effective manner. Centura products include an embedded database that scales from
Smart Cards to the Web, and object oriented application development tools.
Centura products are designed to be deployed in both thin- and fat-client
environments, using business logic objects that can be reused in multi-tier
architectures in distributed environments. The Company's product lines include
an embedded database, (SQLBASE), application development tools, (CENTURA TEAM
DEVELOPER, THE 32-BIT VERSION OF SQLWINDOWS, AND CENTURA NET.DB) and PC to
mainframe connectivity products (SQLHOST). These products are expected to
constitute the majority of the Company's net revenues for the foreseeable
future. The Company cannot accurately predict the exact timing of new product
releases or enhancements. Any failure to deliver products as scheduled, or such
products' failure to achieve early market acceptance, could have a material
adverse effect on the business, operating results and financial condition of the
Company. The Company distributes its products in the United States and
internationally through a corporate sales organization consisting of the
Company's internal sales force complimented by marketing arrangements with
vertical software partners, hardware original equipment manufacturers and
systems integrators, and a channel sales organization consisting of value-added
resellers and distributors. See "Item 1. Business--Risk Factors--New Product

    The Company has experienced in the past and may in the future continue to
experience significant fluctuations in quarterly operating results. The Company
reported a loss of $0.6 million for fiscal year 1997, a profit of $2.0 million
for 1996, and a loss of $44.1 million for 1995. Beginning in the fourth quarter
of 1997, the Company refocused and restructured its operations to leverage its
core technological competencies into next generation products, which include
embeddable databases and continue to embrace object oriented application
development and both thin- and fat-client environments. With the addition of
CENTURA NET.DB, the Company's products now provide a comprehensive architecture
for the development and deployment of information systems and applications from
a host environment, through two-tier client/server and SQL databases, to the
multi-tier environment of the World Wide Web. The Company recognized total
restructuring charges of $1.0 million in 1997 and approximately $5.4 million in
1995. There can be no assurance that the restructuring efforts the Company has
engaged in to date will be successful or that the Company will be able to
sustain profitability on a quarterly or annual basis. Many of the Company's
product licensing arrangements are subject to revenue recognition on a per-unit
deployed basis as the Company's deferred obligation to its customers is
gradually extinguished. Revenue recognition in such cases is therefore dependent
upon the business activities of the Company's customers and the timely and
accurate reporting of such activities to the Company, which makes predictability
of the related revenue extremely uncertain. Although the Company has operated
historically with little or no backlog of traditional boxed product shipments,
it has experienced a seasonal pattern of product revenue decline between the
fourth quarter and the succeeding first quarter, contributing to lower worldwide
product revenues and operating results during such quarters. It has generally
realized lower European product revenues in the third quarter as compared to the
rest of the year. The Company has also experienced a pattern of recording a
substantial portion of its revenues in the third month of a quarter. As a
result, product revenues in any quarter are dependent on orders booked in the
last month. Accordingly, any significant shortfall in sales of the Company's
products in relation to the Company's expectations could have an immediate
adverse impact on the Company's business, operating results and financial
condition.

To the extent that the Company's expenses exceed expected revenues in any fiscal
period, its business, operating results and financial condition could be
materially and adversely affected. Due to the foregoing factors, it is likely
that the Company's operating results may, during any fiscal period, fall below
the expectations of securities analysts and investors. See "Part I, Item 1.
Business, Risk Factors--Recent Company Losses; Fluctuations in Quarterly
Results."
 
RECENT DEVELOPMENTS
 
    SALE AND CONVERSION OF NOTE PAYABLE.  In February 1998, Computer Associates,
Inc. ("CA"), and Newport Acquisition Company, LLP ("NAC") entered into a Note
Purchase and Sale Agreement and the Company and NAC entered into a Note
Conversion Agreement (the "Agreements"). Under the terms of the Agreements, a
promissory note, plus accrued interest, in the amount of $12.3 million, payable
to CA (the "CA Note") was acquired by NAC, and immediately converted into
11,415,094 shares of the Company's common stock (the "Shares"). In February
1998, in connection with the Agreements, the Company entered into a Warrant
Purchase Agreement with CA wherein the Company sold and issued to CA, at an
issuance price of $.001 per share, a warrant to purchase 500,000 shares of the
Company's common stock. The warrant is exercisable at $1.906 per share and
expires on February 28, 2003.
 
    PRIVATE PLACEMENT.  Also in February 1998, pursuant to the terms of Stock
Purchase Agreements, the Company completed a private placement of 2,330,191
shares of the Company's common stock (the "Private Placement"), resulting in net
proceeds to the Company, after deducting estimated transaction costs, of
approximately $1.9 million. Under the terms of the Stock Purchase Agreements,
the Company has agreed to register the shares, issued pursuant to the Stock
Purchase Agreements under the Securities Act of 1933, no later than May 29,
1998. In connection with the Private Placement the Company issued warrants to
purchase 582,548 shares of the Company's common stock. The warrants are
exercisable at $1.25 per share and expire on February 28, 2003. Also, in
consideration of services rendered in connection with the Private Placement, the
Company issued to Rochon Capital Group, Ltd. Warrants to purchase 354,717 shares
of the Company's common stock at an exercise price of $2.12 (the "Rochon
Warrants"). The Rochon warrants expire on February 27, 2003. Transaction costs
associated with both the Agreements and the Private Placement are estimated to
be approximately $0.6 million. See Note 13, of Notes to The Consolidated
Financial Statements.
 
    The Company had, on a pro-forma basis, including the effect of the
Agreements and the Private Placement, deficit working capital of $4.3 million
and net shareholders equity of $4.0 million at December 31, 1997.
 
    In addition, at December 31, 1997 the Company did not meet the Nasdaq
minimum tangible net worth requirements for continued listing on the Nasdaq
National Market. On January 13, 1998, the Company was notified that effective
January 15, 1998, the Company's shares were to be listed on The Nasdaq SmallCap
Market (the "SmallCap Market") and that continued listing on the Small Cap
Market was contingent upon meeting listing standards adopted by the NASD,
effective February 27, 1998. At February 27, 1998, including, on a pro-forma
basis, the effect of the Agreements and the Private Placement, the Company had
met all SmallCap Market listing requirements as required by the NASD. Continued
listing on the SmallCap Market is predicated on the Company continuing to meet
the listing requirements adopted by the NASD.

</TABLE>
 
    NET PRODUCT REVENUES.  Net product revenues for 1997 decreased 10% to $40.7
million from $45.5 million in 1996 primarily due to decreased sales of
SQLWINDOWS. Customers continued to migrate from the 16-bit to the 32-bit
environment offered by the CENTURA TEAM DEVELOPER product, which partially
offset the decline in SQLWINDOWS sales. Sales of the Company's SQLBASE products
increased to $24.5 million or 60% of net product revenues in 1997 from $23.8
million or 52% of net product revenues in 1996. The CENTURA TEAM DEVELOPER
product line, released in May 1996, accounted for $10.7 million or 26% of net
product revenues for 1997 compared with $8.5 million or 19% of net product
revenues in 1996. Net product revenues for 1996 decreased 8% from $49.4 million
in 1995 primarily due to decreased sales of SQLWINDOWS. Sales of SQLBASE
products in 1996 decreased slightly from $24.8 million or 50% of net product
revenue in 1995. Sales of other tools and connectivity software accounted for
$5.5 million or 14%, $13.1 million or 29% and $4.0 million or 8% of net product
revenues for 1997, 1996 and 1995, respectively. International revenue accounted
for 63%, 67% and 66% of total net product revenues for 1997, 1996 and 1995,
respectively.
 
    NET SERVICE REVENUES.  Net service revenues decreased 3% to $17.2 million in
1997 from $17.8 million in 1996. The Company believes the decrease corresponds
to the overall decrease in net product revenues experienced in 1997, partially
offset by renewals of customer support and service agreements from prior
 
                                       32
<PAGE>
years. Net service revenues increased in 1996 from $16.3 million in 1995 due
primarily to a larger installed customer base, inception of a group focusing on
sales of license maintenance and telephone support and marketing programs
designed to encourage customers to reinstate support. License maintenance and
telephone support contracts are typically paid in advance, and revenue is
recognized ratably over the term of the contract. International service revenues
accounted for 46%, 41% and 46% of total net service revenues for 1997, 1996 and
1995, respectively.
 
    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 currently intends to adopt for transactions
entered into in the fiscal year beginning January 1, 1998. SOP 97-2 provides
guidance on recognizing revenue for software transactions and supersedes SOP
91-1, "Software Revenue Recognition". The Company believes that the adoption of
SOP 97-2 will not have a significant impact on its current licensing or revenue
recognition practices.
 
    COST OF PRODUCT REVENUES.  Cost of product as a percentage of product
revenues was 12%, 11% and 18% for 1997, 1996 and 1995, respectively. In December
1995, the Company completed a financial restructuring which included a decision
to consolidate all warehouse and manufacturing functions into a single new
vendor. This resulted in a non-recurring charge against cost of revenues for an
estimated write-off of raw materials of approximately $0.6 million and led to a
more efficient production process which contributed to the reduced cost of
product in 1997 and 1996 from 1995 levels. Cost of product includes the cost of
subcontracted production and the amortization of capitalized software. Cost of
product varies significantly by distribution channel. Channel sales typically
involve sales of packaged products and, as a result, generally have higher costs
of production than embedded applications or large scale deployment sales, which
generally involve software reproduction licenses.
 
    In accordance with Statement of Financial Accounting Standards No. 86,
"Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise
Marketed", the Company capitalizes internal development costs on a project when
the technological feasibility of such project has been determined. The Company
ceases capitalizing such expenses when the products derived from the project are
released for sale. The capitalized costs are then amortized ratably over the
useful life of the products, generally estimated to be two to three years.
Amortization of capitalized software costs, which include the amortization
software purchased from third parties, increased to $2.7 million in 1997 from
$1.6 million in 1996. Amortization of capitalized software costs, including one
time charge to write-off capitalized software, were $2.2 million in 1995. See
Notes 2 and 3 of Notes to Consolidated Financial Statements.
 
    COST OF SERVICE REVENUES.  Cost of service revenues, as a percentage of
service revenues, decreased to 43% in 1997 from 54% in 1996 and 66% in 1995.
Cost of service consists primarily of personnel costs related to maintenance,
training and technical support. In December 1995 and August 1997, the Company
completed operational restructurings which encompassed outsourcing certain
support functions. The outsourcing activities enabled a lower infrastructural
cost of service while maintaining adequate levels of support. It is likely that
the Company will increase the levels of technical service in 1998 and as such,
the cost of service as a percentage of service revenues may also increase, to
the extent that service revenues do not grow at the same rate.
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses, consisting
principally of salaries, sales commissions and costs of advertising and
marketing campaigns, decreased 10% to $26.2 million in 1997 from $29.1 million
in 1996. In 1996, sales and marketing expenses decreased 32% from $42.9 million
in 1995. Sales and marketing expenses represented 45%, 46% and 65% of net
revenues in 1997, 1996 and 1995, respectively. The decrease in sales and
marketing expenses in 1997 was due to reductions in staffing, including the
elimination of portions of the field sales organization which were focussed on
the Foresite product which the Company discontinued in the fourth quarter of
1997. The decrease in sales and marketing expenses in 1996 as compared with 1995
related to the elimination of the telebusiness product
 
                                       33
<PAGE>
sales organization and the reduction of marketing staff and programs with the
objective of targeting marketing at enterprise client/server solution providers.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  The table below sets forth gross
research and development expenses, capitalized internal software development
costs, and net research and development expenses in dollar amounts and as a
percentage of net revenues for the periods indicated:
 
<TABLE>
<CAPTION>
                                                                   YEAR ENDED DECEMBER 31,
                                                               -------------------------------

                                                                       (IN THOUSANDS)

                                                               ---------  ---------  ---------
As a percentage of net revenues:
  Gross research and development expenses....................         19%        20%        25%
  Net research and development expenses......................         17%        17%        22%
</TABLE>
 
    Research and development expenses decreased 12% to $9.7 million in 1997 from
$11.0 million in 1996. The decrease reflects a reduction in staffing and
associated continuing engineering costs required to develop new products in
1997. The Company anticipates that development costs will increase in 1998 as
the Company expands its efforts to leverage core technologies into next
generation products. Research and development expenses in 1995 reflected a $3.4
million write-off of previously capitalized software development costs in
conjunction with the Company's restructuring efforts in that year. After
accounting for this one-time charge, research and development expenses were
essentially flat in 1996 as compared with 1995. The Company believes that the
development of new products and the enhancement of existing products, are
essential to its continued success, and the Company intends to continue to
devote substantial resources to new product development.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased 5% to $7.0 million in 1997 from $6.7 million in 1996, due principally
to increases in costs to retain key personnel, offset by staffing reductions in
the second half of 1997. General and administrative expenses were $11.0 million
in 1995 which included an approximate $1.3 million one time charge for
accounting and professional fees for re-audits of the 1993 and 1994 fiscal year
financial statements and the audit of the 1995 fiscal year financial statements.
These expenses represented 12%, 10% and 17% of net revenues in 1997, 1996 and
1995, respectively. In 1995 and 1997, the Company completed operational
restructuring which included staff reductions and the abandonment of certain MIS
projects which led to reduced general and administrative expenses in 1996 as
compared with 1995. See: --Year 2000 Issue.
 
    LITIGATION SETTLEMENT--CLASS ACTION LAWSUIT.  (See Note 7 of Notes to
Consolidated Financial Statements). The Company reached a binding settlement
agreement with plaintiffs' counsel in a lawsuit filed against the Company and
certain of its officers and directors by a holder of the Company's common stock
and gained court approval of the settlement agreement on September 30, 1996. As
part of the settlement, the Company agreed to provide up to a maximum of
2,500,000 shares of its common stock to a fund to be distributed among the
members of the plaintiff class. As of December 31, 1997, 2,500,000 shares have
been issued and distributed under the settlement agreement and no additional
shares are required to be issued. The 1995 Consolidated Financial Statements
include $15.3 million in litigation expense arising from the settlement
agreement and associated legal expenses.
 
    ACQUISITION EXPENSES.  On January 6, 1997, in an effort to expand its
product offerings in areas complimentary with the Company's core products,
technology and Internet applications, the Company entered into a definitive
agreement to acquire Infospinner, Inc. (Infospinner) of Richardson, Texas (the
"Merger Agreement"). The Company did not obtain the majority vote of its
shareholders required for the
 
                                       34
<PAGE>
approval of the proposed merger, and as such, Infospinner elected to exercise
its right, pursuant to the Merger Agreement, to terminate the transaction. In
connection with the Merger Agreement, the Company entered into a non-exclusive
distribution agreement with Infospinner which was subsequent terminated. See
"Restructuring expenses."
 
    RESTRUCTURING EXPENSES.  Beginning in the second half of 1997, the
distribution agreement with Infospinner terminated and the Company restructured
its operations to leverage its core technological competencies into next
generation products, which include embeddable databases and development tools
that continue to embrace object oriented development and both thin- and
fat-client environments. In 1997 the Company incurred charges related to its
restructuring efforts in the amount of approximately $1.5 million, which
included the write-off of prepaid distribution royalties in connection with the
termination of the Infospinner distribution agreement and severance costs,
offset by the reversal of approximately $0.5 million in existing restructuring
reserves, originally recorded in 1995. The results of operations for 1996
include the reversal of $0.2 million of restructuring reserves due to a change
in estimated employee reduction costs. In 1995 the Company incurred
restructuring costs of $5.0 million related primarily to severance, write-offs
of purchased technology and prepaid license fees, facilities charges associated
with early termination of leases and cancellations of distributor agreements.
There can be no assurance that the restructuring efforts the Company has engaged
in to date will be successful or that the Company will be able to achieve
consistent levels of profitability on a quarterly or annual basis. In addition,
there can be no assurance that the Company's management will not deem it
appropriate to undertake other major restructuring efforts in the future or to
what degree any of these efforts will result in improved operational
performance, if at all. See "Item I Business--"Company Strategies" and "--Risk
Factors--Change in Strategic Direction: Restructuring" and "--New Product Risks;
Rapid Technological Change."
 
    In addition to the restructuring charges detailed above, the Company took
certain one-time charges that were reflected in its 1995 operating results.
These charges included $1.3 million in accounting and related professional fees
for audits of the 1995, 1994 and 1993 financial statements, charged to general
and administrative expense; a $3.4 million write-off of capitalized software
development expense, charged to research and development; and $0.6 million in
liquidation of inventories, charged to cost of revenues.
 
    OTHER INCOME (EXPENSE), NET.  Other income (expense), net is comprised of
interest income, interest expense and gains or losses on foreign currency
transactions. The Company's gains or losses from foreign currency transactions
have fluctuated from period to period, primarily as a result of fluctuating
values of the U.S. dollar and instability in European and Latin American
currency markets. The Company recorded a foreign currency loss of approximately
$1.0 million in 1997, principally due to the decline in the value of certain
European currencies in the first quarter of 1997. The Company recorded a foreign
currency gain of $0.2 million in 1996 and a loss of $0.4 million in 1995. The
Company expanded its hedging program in the second half of 1997 in an effort to
hedge up to a targeted 90% of its exposure to foreign currency fluctuation. The
costs of currency hedging are reflected in the reported gains and losses of
foreign currency transactions. The Company anticipates that it will continue the
hedging program in 1998. Nonetheless, a decrease in the value of foreign
currencies relative to the value of the U.S. dollar could result in losses from
foreign currency transactions. The Company's net interest expense was $0.8
million in 1997 and $0.2 million in 1996 and the Company had net interest income
of $0.4 million in 1995. The decrease in interest income and the increase in
interest expense over these periods is due principally to the decrease in cash
available for investment.
 
    Sales of the Company's products are denominated both in local currencies of
the respective geographic region and in U.S. dollars, depending upon the
economic stability of that region and locally accepted business practices.
Accordingly, any increase in the value of the U.S. dollar relative to local
currencies in these markets may negatively impact revenues, results of
operations and financial condition. An increase in the relative value of the
U.S. dollar would serve to increase the relative foreign currency cost to the
customer of a U.S. dollar denominated purchase, which may negatively affect the
Company's
 
                                       35
<PAGE>
sales in those markets. The U.S. dollar value of a sale denominated in a
region's local currency decreases in proportion to relative increases in the
value of the U.S. dollar.
 
    PROVISION FOR INCOME TAXES.  The provision for income taxes was $0.1 million
in 1997, $0.5 million in 1996 and $1.1 million in 1995. The provision for income
taxes related primarily to foreign withholding taxes. As of December 31, 1997,
the Company had net operating loss carryforwards of approximately $70.2 million
available to offset future federal taxable income and $30.8 million available to
offset future state taxes, which expire in 2012. The availability and timing of
these loss carryforwards to offset future taxable income may be limited due to
the occurrence of certain events, including certain changes in ownership
interests. At December 31, 1997, 1996 and 1995, the Company fully reserved its
deferred tax assets due to the existence of uncertainty of the Company's ability
to realize the deferred tax assets. The Company does not anticipate that recent
developments, resulting in the issuance of approximately 13.7 million shares of
common stock, will impair its ability to utilize net operating loss
carryforwards available at December 31, 1997. See Note 8 and Note 13 of Notes to
Consolidated Financial Statements and "--Recent Developments."
 
    YEAR 2000 ISSUE.  The Company has commenced, for all of its information
systems, a year 2000 date conversion project to address all necessary code
changes, testing and implementation of mission critical applications. The "Year
2000 Issue" arises because most computer systems and programs were designed to
handle only a two-digit year, as opposed to a four digit year. When the year
2000 begins these computers may interpret "00" as the year 1900 and could either
stop processing date-related computations or could process them incorrectly. The
Year 2000 Issue creates risk for the Company from unforeseen problems in its
internal computer systems and from third parties with which the Company
interacts. Such failures of the Company's and/or third parties' computer systems
could have a material impact on the Company's ability to conduct its business,
and to process and account for the transfer of funds electronically. Management
has not completed its assessment of all of the potential Year 2000 compliance
expenses and the related potential effect on the Company's earnings.
 
    INFLATION.  The Company believes that inflation has not had a material
impact on the Company's operating results and does not expect inflation to have
a material impact on the Company's operating results in 1998.
 
LIQUIDITY AND CAPITAL RESOURCES:
 
    At December 31, 1997, the Company had a deficit working capital position of
approximately $18.2 million and a net shareholders deficit of approximately $10
million, due principally to deferred product and support revenue of $14.6
million, and a subordinated note, including accrued interest, in the amount of
approximately $12.1 million.
 
    In February 1998, the Company entered into a series of transactions which
resulted in the reduction of its working capital deficit to $4.3 million
(deficit) and its net shareholders deficit to $4.0 million net shareholders
equity, on a pro forma basis. See "--Recent Developments."
 
    The Company reached a binding settlement agreement with plaintiffs' counsel
in a lawsuit filed against the Company and certain of its officers and directors
by a holder of the Company's common stock and gained court approval of the
settlement agreement on September 30, 1996. As part of the settlement, the
Company agreed to provide up to a maximum of 2,500,000 shares of its common
stock to a fund to be distributed among the members of the plaintiff class. As
of December 31, 1997, 2,500,000 shares have been issued and distributed under
the settlement agreement and no additional shares are required to be issued. See
Note 6 of Notes to Consolidated Financial Statements.
 
    The Company entered into an unsecured floating rate convertible subordinated
note for $10.0 million (the "Note") and a related agreement with Computer
Associates Inc. ("CA") (the "CA Agreement") in March 1995. The Note would mature
on March 31, 1998 and could be convertible into common stock at
 
                                       36
<PAGE>
the Company's option on May 1, 1998 for a number of shares based on the market
price of the Company's common stock at the time of conversion if certain
conditions had been met. Interest on the Note is calculated based on the
one-month LIBOR plus 1.25% and was payable quarterly. At the Company's option
interest payments could be deferred until the principal was due. Pursuant to the
CA Agreement, the ability of the Company to convert the Note to common stock
required the Company to maintain a minimum market capitalization of $40.0
million commencing on (and including) November 1, 1997, and continuing through
the duration of the Note (the "Minimum Market Capitalization Requirement"). If
the Company did not meet the Minimum Market Capitalization Requirement, the
Company would lose the option to convert the Note into common stock, and all
outstanding principal and interest would be due and payable on March 31, 1998.
 
    At December 31, 1997 the Company had approximately $6.0 million in unsecured
foreign currency contracts, denominated in various European currencies, as part
of a program to hedge the financial exposure arising from foreign denominated
monetary assets and liabilities.
 
    The deferred product and support revenue of $14.6 million at December 31,
1997 reflects a delay in recognition of revenue in accordance with contractual
agreements and requires minimal resources of the Company.
 
    Net cash used by operating activities was $3.3 million in 1997, $7.7 million
in 1996 and $5.1 million in 1995. The use of cash in 1997 was due principally to
decreases in deferred revenue and accounts payable and accrued liabilities,
offset by depreciation and amortization and decreases in accounts receivable. In
1996, net income and increases in depreciation and amortization in 1996 were
offset by decreases in accounts payable and accrued liabilities, litigation
expense and deferred revenue. In 1995, increases in accrued litigation,
depreciation and amortization, adjustments for capitalized software, deferred
revenue, and provision for sales returns and allowances were offset by the net
loss and the increase to accounts receivable. Inventories, which were located at
the Company's third party turnkey vendor, decreased by $1.1 million in 1995.
This decrease in 1995 was due in part to planned reductions of inventories and a
consolidation of worldwide inventories into a single third party vendor
location.
 
    Cash used in investing activities was $1.6 million in 1997, principally due
to the purchase of equipment and capitalized software costs, partially offset by
maturities of investments. Cash provided by investing activities was $4.6
million in 1996, principally due to maturities of investments offset by
acquisition of property and equipment, and capitalization of software
development costs. Cash used in investing activities of $2.7 million in 1995 was
utilized for additions in the amount of $4.0 million of internally developed and
purchased software and $3.1 million in additions to property and equipment,
primarily computer and other capital equipment, partially offset by the sale of
$5.4 million of short-term investments, net of purchases.
 
    Net cash provided by financing activities in 1997 and 1996 totaled $2.2
million and $0.2 million, respectively, primarily as a result of proceeds from
short-term borrowings and issuance of common stock offset by repayment of the
notes payable. Net cash provided by financing activities in 1995 totaled $10.5
million primarily as a result of the $10.0 million subordinated convertible debt
financing by CA.
 
    The Company believes that expected cash flows from operations and existing
cash balances, will be sufficient to meet the Company's currently anticipated
working capital and capital expenditure requirements for the next 12 months. The
Company may, however, choose to raise cash for operational or other needs
sometime in the future. If the Company needs further financing, there can be no
assurance that it will be available on reasonable terms or at all. Any
additional equity financing will result in dilution to the Company's
shareholders.
 
    The Company's capital requirements also may be affected by acquisitions of
businesses, products and technologies that are complementary to the Company's
business, which the Company considers from time to time. The Company regularly
evaluates such opportunities. Any such transaction, if consummated, may further
reduce the Company's working capital or require the issuance of equity.

    In January 1998, the Company entered into a $5.0 million asset based loan
facility with Coast Business Credit. The loan provides for borrowings of up to
$5.0 million, secured by the Company's accounts receivable, combined with a $0.5
million capital equipment facility. The facility bears interest at a rate of
2.25% above the Bank of America Reference Rate, and provides for the ability to
reduce interest costs based on the achievement of certain financial covenants.
The facility matures in January 2000 and provides for the ability to extend the
agreement for one year at the option of the Company. The facility replaces the
Pacific Business Funding Corporation accounts receivable factoring agreement
entered into by the Company in June 1997.
 
FACTORS THAT MAY AFFECT FUTURE RESULTS
 
    The Company has experienced in the past and expects in the future to
continue to experience significant fluctuations in quarterly operating results.
The Company has at times recognized a substantial portion of its net revenues in
the last month or last few weeks of a quarter. The Company generally ships
products as orders are received and, therefore, has little or no backlog. As a
result, quarterly sales and operating results generally depend on a number of
factors that are difficult to forecast, including, among others, the volume and
timing of and ability to fulfill orders received within the quarter. Operating
results also may fluctuate due to factors such as demand for the Company's
products, introduction, localization or enhancement of products by the Company
and its competitors, market acceptance of new products, reviews in the industry
press concerning the products of the Company or its competitors, changes or
anticipated changes in pricing by the Company or its competitors, mix of
distribution channels through which products are sold, mix of products sold,
returns from the Company's distributors and general economic conditions. As a
result, the Company believes that period-to-period comparisons of its results of
operations are not necessarily meaningful and should not be relied upon as any
indication of future performance.
 
    In addition, because the Company's staffing and other operating expenses are
based in part on anticipated net revenues, a substantial portion of which may
not be generated until the end of each quarter, delays in the receipt or
shipment of orders and ability to achieve anticipated revenue levels can cause
significant variations in operating results from quarter to quarter. The Company
may be unable to adjust spending in a timely manner to compensate for any
unexpected revenue shortfall. Accordingly, any significant shortfall in sales of
the Company's products in relation to the Company's expectations could have an
immediate adverse impact on the Company's business, operating results and
financial condition. In addition, the Company currently intends to increase its
operating expenses to fund greater levels of sales and marketing operations and
expand distribution channels. To the extent that such expenses proceed or are
not subsequently followed by increased net revenues, the Company's business,
operating results and financial condition could be materially and adversely
affected.
 
    In the future, the Company may make acquisitions of complementary companies,
products or technologies. Managing acquired businesses entails numerous
operational and financial risks, including difficulties in assimilating acquired
operations, diversion of management's attention to other business concerns,
amortization of acquired intangible assets and potential loss of key employees
or customers of acquired operations. There can be no assurance that the Company
will be able to effectively complete or integrate acquisitions, and failure to
do so could have a material adverse effect on the Company's operating results.
As of the date hereof, the Company has no understanding or agreement with any
other entity regarding any potential acquisition or combination, the
consummation of which is probable.
 
    In addition, quarterly operating results of the Company will depend on a
number of other factors that are difficult to forecast, including factors listed
in "Item 1. Business, --Risk Factors--Recent Company Losses; Fluctuations in
Quarterly Results".

 of Centura Software Corporation:
 
    In our opinion, the consolidated financial statements listed in the index
appearing under Item 14(a)(1) and (2) on page 61 present fairly, in all material
respects, the financial position of Centura Software Corporation at December 31,
1997 and 1996, 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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. BUSINESS AND RISK FACTORS:
 
    Centura Software Corporation (the "Company"), formerly Gupta Corporation,
develops, markets and supports an integrated set of software solutions for the
PC client/server system market.
 
    On January 6, 1997, the Company entered into a definitive agreement (the
"Agreement") to acquire InfoSpinner, Inc. ("InfoSpinner") of Richardson, Texas.
The completion of the transaction was subject to the approval of both companies'
shareholders as well as other legal requirements. In addition, under the terms
of the Agreement, either party had the right to terminate the transaction if the
merger had not been consummated by April 30, 1997. As of April 30, 1997, the
Company did not obtain the majority vote of the shareholders required for the
approval of the proposed merger, and as a result, the board of directors of
InfoSpinner elected to exercise its right to terminate the transaction.
 
    The Company has in the past experienced significant losses from operations,
and as a result its liquidity and capital resources have declined. Management
implemented measures which improved its operating results, including
cost-cutting measures, new product introductions and refocused marketing and
technological efforts on the Company's core competencies. However, the Company's
future profitability is subject to certain risks, including competition from
larger companies with greater financial resources, its ability to raise
additional financing, if needed, its ability to retain key personnel and its
ability to successfully develop, produce and market new products. Management
believes that the recent measures combined with the introduction of new products
and the refocus on core competencies has heightened the possibility of the
Company to improve cash flow.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reported
period. Actual results could differ materially from those estimates.
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
    PRINCIPLES OF CONSOLIDATION.  The consolidated financial statements include
the financial statements of the Company and its wholly-owned subsidiaries. All
significant intercompany balances and transactions have been eliminated in
consolidation.
 
    CASH AND CASH EQUIVALENTS.  The Company considers all highly liquid
investments purchased with an original maturity of three months or less to be
cash equivalents.
 
    FINANCIAL INSTRUMENTS.  Financial instruments that potentially subject the
Company to concentrations of credit risk consist principally of cash,
investments, and accounts receivable. At December 31, 1997, the Company's cash
and cash equivalents include Money Market accounts and Certificates of Deposit.
Cost approximates market value of the securities at December 31, 1997.
 
    The Company generally does not require collateral for its receivables and
maintains reserves for potential credit losses.
 
    The Company accounts for investments under the Statement of Financial
Accounting Standards No. 115 ("SFAS 115"), "Accounting for Certain Investments
in Debt and Equity Securities". SFAS 115 establishes standards for financial
accounting and reporting for investments in equity securities that have readily
determinable fair values and for all investments in debt securities. Each
investment is classified into one of three categories: held-to-maturity,
available-for-sale or trading. Investments which the Company

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
has the intent and ability to hold until maturity are classified as
held-to-maturity and are recorded at amortized cost.
 
    The Company enters into forward contracts to reduce the risks associated
with foreign currency fluctuations on net assets denominated in foreign
currencies. At December 31, 1997, the Company had $5,980,000 in forward
contracts denominated in four European currencies; German Deutsche Marks,
British Pounds Sterling, Netherland Guilders, and Italian Lire. At December 31,
1996 the Company had $400,000 forward contracts denominated in Mexican Pesos.
 
    The carrying value of all other financial instruments approximate their
respective fair values. See Note 13, "Subsequent Events".
 
    INVENTORIES.  Inventories are stated at the lower of cost (determined on a
first-in, first-out basis) or market, and consist principally of finished goods.
 
    PROPERTY AND EQUIPMENT.  Property and equipment are stated at cost.
Depreciation is computed using the straight-line method over the estimated
useful lives of three to five years. Leasehold improvements are amortized over
the life of the lease or the estimated useful life, whichever is shorter.
 
    CAPITALIZED SOFTWARE DEVELOPMENT COSTS.  The Company capitalizes internally
generated software development costs and purchased software in compliance with
Statement of Financial Accounting Standards No. 86, "Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed". Capitalization of
internally generated software development costs begins upon the establishment of
technological feasibility of the product, which the Company defines as the time
when a complete product is available. The Company makes an ongoing assessment of
the recoverability of these costs which requires considerable judgment by
management with respect to certain external factors, including but not limited
to, anticipated future gross product revenue, estimated economic life and
changes in software and hardware technology. Internally generated software
development costs capitalized were $1,018,000 and $1,865,000 for the years ended
December 31, 1997 and 1996, respectively. The Company did not capitalize and
purchased software in 1997 and capitalized $1,025,000 of purchased software in
1996.
 
    Amortization of all capitalized software costs begins when a product is
available for general release to customers, and is computed separately for each
product as the greater of (a) current gross revenue for a product to the total
of current and anticipated gross revenue for the product, or (b) the
straight-line method over the remaining estimated economic life of the product,
up to three years. Amortization and adjustments are included in cost of product
revenues and amounted to $2,671,000, $1,644,000 and $5,580,000, which included
the write-off of $3,360,000 in previously capitalized development costs, for the
years ended December 31, 1997, 1996 and 1995, respectively.
 
    FOREIGN CURRENCY TRANSACTIONS.  The functional currency of each foreign
subsidiary is the local currency. For these operations, assets and liabilities
are translated into U.S. dollars at period-end exchange rates, and income and
expense accounts are translated at a rate that approximates the average exchange
rate prevailing during the period. The resulting translation adjustments are
recorded as a separate component of shareholders' equity (deficit). Gains and
losses from foreign currency-denominated transactions effected by the Company's
U.S. operations are included in other income (expense).
 
    REVENUE RECOGNITION.  The Company receives licensing fees from certain
resellers (including original equipment manufacturers) under product licensing
arrangements. Such fees are recorded as revenue as
 
                                       45

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
product is sold and reported to the Company by the reseller when ongoing
significant post delivery obligations exist. When no such obligations exist,
such fees are recorded as revenue when the product is shipped and collectability
is probable. For licensing agreements with end-users, fees are recognized upon
shipment of product, if there are no significant post-delivery obligations and
collectibility is probable. Service revenues from customer maintenance fees for
ongoing customer support and product updates, including maintenance bundled with
software licenses, is recognized ratably over the period of the contract. When
licensing agreements terminate, the Company records any licensing fees
previously not recognized. Revenue from other services, including training, are
recognized as performed. The Company enters into agreements with certain of its
distributors involving boxed product. Revenues from these distributors are
generally recognized when the product is shipped and are reduced by management's
estimate of anticipated stock exchanges based on historical experience. License
maintenance and telephone support contracts are typically paid in advance, and
revenue is recognized ratably over the term of the contract.
 
    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 currently intends to adopt for transactions
entered into the fiscal year beginning January 1, 1998. SOP 97-2 provides
guidance on recognizing revenue on software transactions and supersedes SOP
91-1, "Software Revenue Recognition". The Company believes that the adoption of
SOP 97-2 will not have a significant impact on its current licensing or revenue
recognition practices.
 
    NET INCOME (LOSS) PER SHARE.  The Company has adopted Statement of Financial
Accounting Standards (SFAS) No. 128, "Earnings Per Share" ("SFAS 128"). SFAS 128
requires the presentation of basic earnings per share ("EPS") and diluted EPS,
for companies with potentially dilutive securities, such as options. Earnings
per share for all prior periods have been restated to conform with the
provisions of SFAS 128.
 
    Basic earnings per share is computed using the weighted average number of
shares of common stock. Diluted earnings per share is computed using the
weighted average number of shares of common stock, common equivalent shares
outstanding during the period. Common equivalent shares consist of convertible
preferred stock (using the if converted method) and stock options and warrants
(using the treasury stock method). Common equivalent shares are excluded from
the computation if their effect is antidilutive.
 
    For the year ended December 31, 1996, 149,000 options and warrants to
purchase common stock were included within the computation of diluted EPS.
Antidilutive options and warrants to purchase 4,055,000, 2,935,000, and
3,633,000 shares of common stock were outstanding at December 31, 1997, 1996 and
1995, respectively. Antidilutive convertible debt to convert to 3,774,000 and
1,832,000 shares of common stock were outstanding at December 31, 1996, and
1995, respectively. No such shares were outstanding at December 31, 1997 as the
Company lost the conversion option during 1997.
 
    STOCK-BASED COMPENSATION.  During 1995, the FASB issued Statement of
Financial Accounting Standards No. 123 ("SFAS 123"), "Accounting for Stock-Based
Compensation", which requires companies to measure employee stock compensation
based on the fair value method of accounting or to continue to apply the
provisions of Accounting Principles Board Opinion No. 25 ("APB 25"), "Accounting
for Stock Issued to Employees", and provide pro forma footnote disclosure under
the fair value method described in SFAS 123. The Company adopted SFAS 123 on
January 1, 1996, and will continue to apply the principles of
 
                                       46

APB 25, while providing the pro forma footnote disclosure required by SFAS 123.
See Note 8 "Capital Stock," for the required pro-forma disclosure.
 
    RECENT ACCOUNTING PRONOUNCEMENT.  In June 1997, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 130,
"Reporting Comprehensive Income" ("SFAS 130"). SFAS 130 establishes standards
for the reporting of comprehensive income and its components in a full set of
general-purpose financial statements for periods ending after December 15, 1997.
Reclassification of financial statements for earlier periods for comparative
purposes is required. The Company will adopt SFAS 130 in 1998 and does not
expect such adoption to have a material effect on the consolidated financial
statements.
 
    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures About Segments of An
Enterprise and Related Information" ("SFAS 131"). SFAS 131 revises information
regarding the reporting of operating segments. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. The Company will adopt SFAS 131 beginning in 1998 and has not
evaluated the impact of such adoption on the notes to its consolidated financial
statements.
 
    RECLASSIFICATIONS.  In order to conform to the 1997 presentation, certain
reclassifications have been made to the 1996 and 1995 consolidated financial
statements.

NOTE 4. SHORT-TERM BORROWINGS
 
    On June 26, 1997, the Company entered into a one year agreement to factor,
with recourse, certain accounts receivable. Under the terms of the agreement,
the Company may factor accounts receivable at an advance rate of eighty percent
of such eligible accounts receivable. Interest is calculated at the rate of 1.2%
per month based on the average daily balance outstanding. As of December 31,
1997 total eligible accounts receivable factored were $1,581,000. See Note 8,

    In November 1997, the Company incurred restructuring charges of $1,504,000,
which included a write-off of $640,000 in prepaid royalties, $344,000 of
severance benefits for certain executives and employees and a $520,000 write-off
of other assets, partially offset by the reversal of $474,000 of reserves
established in prior periods due to changes in estimates. The decision to
write-off the existing prepaid royalty and other assets was associated with the
Company's decision to discontinue certain products. At December 31, 1997
$290,000 related to the restructuring charge was included in other current
liabilities. The Company expects to pay all remaining obligations related to
these charges in 1998.

    The Company entered into an unsecured floating rate convertible subordinated
note and related agreement CA (the "CA Agreement") in March 1995 for
$10,000,000. The CA Agreement matures on March 31, 1998 and was convertible into
common stock at the Company's option on the maturity date for a number of shares
based on the market price of the Company's common stock at the time of
conversion. Interest on the note is calculated based on the one-month LIBOR plus
1.25% and is payable quarterly. At the Company's option interest payments may be
deferred until the principal is due. The conversion to common stock requires the
Company to maintain a minimum market capitalization of $40.0 million commencing
on (and including) November 1, 1997, and continuing through the duration of the
note (the "Minimum Market Capitalization Requirement"). The Company did not meet
the Minimum Market Capitalization Requirement and lost the option to convert the
note into common stock. Accrued interest totaled $2,112,000 and $1,300,000 and
is included in other accrued liabilities and other long-term liabilities at
December 31, 1997 and 1996, respectively. See Note 13. "Subsequent Events".

    On May 2, 1994, a lawsuit was filed against the Company and certain of its
officers and directors, by a holder of the Company's common stock, on his own
behalf and purportedly on behalf of a class of others similarly situated. The
lawsuit was subsequently amended, and alleged that the Company made false and
misleading statements and failed to disclose material information relating to
existing business conditions and the Company's prospects and that officers and
directors violated the insider trading laws. The plaintiff was seeking damages
of an unstated amount.
 
    The Company reached a binding settlement agreement (the "Settlement
Agreement") with plaintiffs' counsel in the lawsuit, and gained court approval
of the Settlement Agreement on September 30, 1996. As part of the settlement,
the Company agreed to provide up to a maximum of 2,500,000 shares of its common
stock (the "Settlement Shares") to a fund to be distributed among the members of
the plaintiff class. As of December 31, 1997, 2,500,000 shares have been issued
and distributed under the settlement agreement and no additional shares are
required to be issued. The 1995 Consolidated Financial Statements include
$15,300,000 in litigation expense arising from the settlement agreement and
associated legal expenses.
 
    On September 17, 1997, Technology Venture (Software) Holdings Limited,
formerly known as Eagerquest Investments Limited ("Eagerquest") filed suit
against the Company in the United States District Court for the Central District
of California alleging that the Company acted improperly in terminating its
contract with Eagerquest for the distribution of the Company's products in the
territories of Hong Kong and China and that the Company's actions illegally
damaged Eagerquest. The Company believes that its actions were within its rights
under its contract with Eagerquest and that the allegations are without merit.
The Company intends to defend itself vigorously in this action and that the
outcome will not have a material adverse affect on the Company's financial
situation or business prospects.

ISOP"), 1,000,000 shares of common stock were initially reserved for issuance to
eligible employees, directors and consultants. In September, 1996, an additional
1,000,000 shares were reserved increasing the total to 2,000,0000 shares. Under
the 95 ISOP, incentive stock options or nonstatutory stock options may be

    DIRECTORS STOCK OPTION PLAN.  Under the 1996 Directors' Stock Option Plan
(the "96 DSOP"), 500,000 shares of common stock have been reserved for issuance
to non-employee directors of the Company. The 96 DSOP provides that each outside
Director will be automatically granted a non-statutory stock option to purchase
50,000 shares of common stock on the later of the following events occurring:
(a) the effective date of the plan, or (b) the date on which such person first
becomes a non-employee Director, provided that such Director agrees to cancel
all options granted to such Director from a prior Directors' stock option plan,
other than the initial 20,000 shares granted to the Director under such plan.
The options become exercisable in installments cumulatively as to 1/48 of the
shares on each of the first forty-eight monthly anniversaries of the grant date.
The options will remain exercisable for up to ninety days following the
optionee's termination of service as a director of the Company unless such
termination is a result of death, in which case the options will remain
exercisable for up to 6 month period. Options are granted at a price equal to
the fair market value of the Company's common stock on the date of the grant.
Options granted under the 96 DSOP have a term of ten years. 200,000 options were
granted and 50,000 options were canceled in 1997. 250,000 options were granted
and 100,000 options were canceled in 1996 under the 96 DSOP. At December 31,

    EMPLOYEE STOCK PURCHASE PLAN.  Under the 1992 Employee Stock Purchase Plan
(the "ESPP"), 300,000 shares of common stock were initially reserved for
issuance to eligible employees. In 1996, 100,000 additional shares of common
stock were reserved for issuance to eligible employees increasing the total to
400,000. The ESPP permits employees to purchase common stock through payroll
deductions, which may not exceed 10% of an employee's compensation, at a price
equal to the lower of 85% of the fair market value of the Company's common stock
at the beginning or end of the offering period. The ESPP became effective upon
the Company's initial public offering and 132,000, 100,000 and 98,000 purchase
rights were issued in 1997, 1996 and 1995, respectively. At December 31, 1997
there were no ESPP shares available for employee purchases.
 
    WARRANTS.  In June 1997, the Company issued warrants to purchase 90,000 and
10,000 shares of common stock to Pacific Business Funding Corporation and its
affiliate Sand Hill Capital, LLC, at an exercise price of $2.09 per share. The
warrants were valued at $103,000 using a risk-free rate of 6.33% and a
volatility factor of 55%, and the related charge is included in general and
administrative expenses in 1997. The warrants expire on June 30, 2002.
 
    Warrants to purchase 100,000 shares of common stock were issued by the
Company on November 22, 1996 in connection with a potential acquisition of
InfoSpinner, Inc. These warrants were valued at $165,000, using a risk-free rate
of 5.97% and a volatility factor of 55%, and are included in acquisition
expenses in 1996. Exercise of the warrants was contingent upon completion of the
proposed acquisition. As the Company did not obtain the majority vote of its
shareholders required for approval of the proposed acquisition within the
designated time frame, the warrants have been cancelled.

    The fair value of each stock option granted under the 86 and 95 ISOP and 96
DSOP was estimated using the Black-Scholes model with the following assumptions:
zero dividend yield; an expected life of 48 months; weighted average expected
volatility of 65%, 63.54% and 67.49% in 1997, 1996 and in 1995; and a weighted
average risk-free interest rate of 6.20%, 5.57% and 6.21% in 1997, 1996 and
1995. The weighted average fair value of stock options granted under the 95
ISOP, the 96 DSOP and non-plan options for the years ended December 31, 1997,
1996, and 1995 were $.91, $3.06 and $5.28, respectively.
 
    The fair value of the shares granted under the ESPP is considered to have an
immaterial impact on this calculation.
 
    The above pro forma amounts include compensation expense based on the fair
value of stock options granted and vesting during the years ended December 31,
1997, 1996 and 1995, and exclude the effects of stock options granted prior to
January 1, 1995. Accordingly, the above pro forma net income and net income per
share are not representative of the effects of computing stock compensation
expense using the fair value method for future periods.
 
    SHAREHOLDER RIGHTS PLAN.  In August 1994, the Company adopted a Shareholder
Rights Plan pursuant to which one Preferred Share Purchase "Right" was
distributed for each outstanding share of common stock. Each Right entitles
shareholders to purchase a fraction of a share of Preferred Stock at an exercise
price of $60.00 upon certain events. The Rights expire on August 3, 2004, unless
earlier redeemed by the Company.

NOTE 8. CAPITAL STOCK (CONTINUED)
    The Rights become exercisable if a person acquires 15% or more of the
Company's common stock or announces a tender offer that would result in such
person owning 15% or more of the Company's common stock. If the Rights become
exercisable, the holder of each Right (other than the person whose acquisition
triggered the exercisability of the Rights) will be entitled to purchase, at the
Right's then current exercise price, a number of shares of the Company's common
stock having a market value of twice the exercise price. In addition, if the
Company were to be acquired in a merger or the Company sells more than 50% of
its assets or earning power, each Right will entitle its holder to purchase, at
the Right's then current exercise price, common stock of the acquiring company
having a market value of twice the exercise price. The Rights are redeemable by
the Company at a price of $.01 per Right at any time within ten days after a
person has acquired 15% or more of the Company's common stock.

    At December 31, 1997, the Company had net operating loss carryforwards of
approximately $70.2 million available to offset future federal taxable income
and $30.8 million available to offset future state taxes, which expire through
2012. The availability and timing of these carryforwards to offset future
taxable income may be limited due to the occurrence of certain events, including
certain changes in ownership interests. At December 31, 1997 and 1996, the
Company fully reserved its deferred tax assets due to the existence of
sufficient uncertainty with respect to its the ability to realize the deferred
tax assets.

Company's accounts receivable, combined with a $500,000 capital equipment
facility. The Facility bears interest at 2.25% above the Bank of America
Reference Rate, and provides for ability to reduce interest cost based on the
achievement of certain financial covenants. The Facility matures in January 2000
and provides for the ability to extend the agreement for one year at the option
of the Company. The facility replaces an accounts receivable factoring agreement
entered into by the Company in June 1997.
 
    SALE AND CONVERSION OF NOTE PAYABLE.  In February 1998, Computer Associates,
Inc. ("CA"), and Newport Acquisition Company, LLP ("NAC") entered into a Note
Purchase and Sale Agreement and the Company and NAC entered into a Note
Conversion Agreement (the "Agreements"). Under the terms of the Agreements, a
promissory note, plus accrued interest, in the amount of $12,251,000, payable to
CA (the "CA Note") was acquired by NAC, and immediately converted into
11,415,094 shares of the Company's common stock (the "Shares"). In February
1998, in connection with the Agreements, the Company entered into a Warrant
Purchase Agreement with CA wherein the Company sold and issued to CA, at an
issuance price of $.001 per share, a warrant to purchase 500,000 shares of the

                                     ARTICLE I
                                          
                                 CORPORATE OFFICES

               
               1.1  PRINCIPAL OFFICE

               The board of directors shall fix the location of the principal 
executive office of the corporation at any place within or outside the State 
of California.  If the principal executive office is located outside such 
state and the corporation has one or more business offices in such state, 
then the board of directors shall fix and designate a principal business 
office in the State of California.

               1.2  OTHER OFFICES

               The board of directors may at any time establish branch or 
subordinate offices at any place or places where the corporation is qualified 
to do business.

                                     ARTICLE II
                                          
                              MEETINGS OF SHAREHOLDERS

               2.1  PLACE OF MEETINGS

               Meetings of shareholders shall be held at any place within or 
outside the State of California designated by the board of directors.  In the 
absence of any such designation, shareholders' meetings shall be held at the 
principal executive office of the corporation.

               2.2  ANNUAL MEETING

               The annual meeting of shareholders shall be held each year on 
a date and at a time designated by the board of directors.  In the absence of 
such designation, the annual meeting of shareholders shall be held on the 
18th of April in each year at 10:00 a.m.  However, if such day falls on a 
legal holiday, then the meeting shall be held at the same time and place on 
the next succeeding full business day.  At the meeting, directors shall be 
elected, and any other proper business may be transacted.

               2.3  SPECIAL MEETING

               A special meeting of the shareholders may be called at any 
time by the board of directors, or by the chairman of the board, or by the 
president, or by one or more shareholders holding shares in the aggregate 
entitled to cast not less than ten percent (10%) of the votes at that meeting.

<PAGE>

               If a special meeting is called by any person or persons other 
than the board of directors or the president or the chairman of the board, 
then the request shall be in writing, specifying the time of such meeting and 
the general nature of the business proposed to be transacted, and shall be 
delivered personally or sent by registered mail or by telegraphic or other 
(facsimile transmission to the chairman of the board, the president, any vice 
president or the secretary of the corporation.  The officer receiving the 
request shall cause notice to be promptly given to the shareholders entitled 
to vote, in accordance with the provisions of Sections 2.4 and 2.5 of these 
bylaws, that a meeting will be held at the time requested by the person or 
persons calling the meeting, so long as that time is not less than 
thirty-five (35) nor more than sixty (60) days after the receipt of the 
request.  If the notice is not given within twenty (20) days after receipt of 
the request, then the person or persons requesting the meeting may give the 
notice.  Nothing contained in this paragraph of this Section 2.3 shall be 
construed as limiting, fixing or affecting the time when a meeting of 
shareholders called by action of the board of directors may be held.

               2.4  NOTICE OF SHAREHOLDERS' MEETINGS

               All notices of meetings of shareholders shall be sent or 
otherwise given in accordance with Section 2.5 of these bylaws not less than 
ten (10) (or, if sent by third-class mail pursuant to Section 2.5 of these 
bylaws, thirty (30)) nor more than sixty (60) days before the date of the 
meeting. The notice shall specify the place, date, and hour of the meeting 
and (i) in the case of a special meeting, the general nature of the business 
to be transacted (no business other than that specified in the notice may be 
transacted) or (ii) in the case of the annual meeting, those matters which 
the board of directors, at the time of giving the notice, intends to present 
for action by the shareholders (but subject to the provisions of the next 
paragraph of this Section 2.4 any proper matter may be presented at the 
meeting for such action).  The notice of any meeting at which directors are 
to be elected shall include the name of any nominee or nominees whom, at the 
time of the notice, the board intends to present for election.

               If action is proposed to be taken at any meeting for approval 
of (i) a contract or transaction in which a director has a direct or indirect 
financial interest, pursuant to Section 310 of the Corporations Code of 
California (the "Code"), (ii) an amendment of the articles of incorporation, 
pursuant to Section 902 of the Code, (iii) a reorganization of the 
corporation, pursuant to Section 1201 of the Code, (iv) a voluntary 
dissolution of the corporation, pursuant to Section 1900 of the Code, or (v) 
a distribution in dissolution other than in accordance with the rights of 
outstanding preferred shares, pursuant to Section 2007 of the Code, then the 
notice shall also state the general nature of that proposal.

               2.5  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

               Written notice of any meeting of shareholders shall be given 
either (i) personally or (ii) by first-class mail or (iii) by third class 
mail but only if the corporation has outstanding shares held of record by 
five hundred (500) or more persons (determined as provided in Section 605 of 
the Code) on the record date for the shareholders' meeting, or (iv) by 
telegraphic or other written communication.  Notices not personally delivered 
shall be sent charges prepaid and shall be addressed to the shareholder at 
the address of that shareholder appearing on the books of the 

                                      -2-

<PAGE>

corporation or given by the shareholder to the corporation for the purpose of 
notice.  If no such address appears on the corporation's books or is given, 
notice shall be deemed to have been given if sent to that shareholder by mail 
or telegraphic or other written communication to the corporation's principal 
executive office, or if published at least once in a newspaper of general 
circulation in the county where that office is located.  Notice shall be 
deemed to have been given at the time when delivered personally or deposited 
in the mail or sent by telegram or other means of written communication.

               If any notice addressed to a shareholder at the address of 
that shareholder appearing on the books of the corporation is returned to the 
corporation by the United States Postal Service marked to indicate that the 
United States Postal Service is unable to deliver the notice to the 
shareholder at that address, then all future notices or reports shall be 
deemed to have been duly given without further mailing if the same shall be 
available to the shareholder on written demand of the shareholder at the 
principal executive office of the corporation for a period of one (1) year 
from the date of the giving of the notice.

               An affidavit of the mailing or other means of giving any 
notice of any shareholders' meeting, executed by the secretary, assistant 
secretary or any transfer agent of the corporation giving the notice, shall 
be prima facie evidence of the giving of such notice.

               2.6  QUORUM

               The presence in person or by proxy of the holders of a 
majority of the shares entitled to vote thereat constitutes a quorum for the 
transaction of business at all meetings of shareholders.  The shareholders 
present at a duly called or held meeting at which a quorum is present may 
continue to do business until adjournment, notwithstanding the withdrawal of 
enough shareholders to leave less than a quorum, if any action taken (other 
than adjournment) is approved by at least a majority of the shares required 
to constitute a quorum.

               2.7  ADJOURNED MEETING; NOTICE

               Any shareholders' meeting, annual or special, whether or not a 
quorum is present, may be adjourned from time to time by the vote of the 
majority of the shares represented at that meeting, either in person or by 
proxy.  In the absence of a quorum, no other business may be transacted at 
that meeting except as provided in Section 2.6 of these bylaws.

               When any meeting of shareholders, either annual or special, is 
adjourned to another time or place, notice need not be given of the adjourned 
meeting if the time and place are announced at the meeting at which the 
adjournment is taken. However, if a new record date for the adjourned meeting 
is fixed or if the adjournment is for more than forty-five (45) days from the 
date set for the original meeting, then notice of the adjourned meeting shall 
be given.  Notice of any such adjourned meeting shall be given to each 
shareholder of record entitled to vote at the adjourned meeting in accordance 
with the provisions of Sections 2.4 and 2.5 of these bylaws.  At any 
adjourned meeting the corporation may transact any business which might have 
been transacted at the original meeting.

                                      -3-
<PAGE>
               2.8  VOTING

               The shareholders entitled to vote at any meeting of 
shareholders shall be determined in accordance with the provisions of Section 
2.11 of these bylaws, subject to the provisions of Sections 702 through 704 
of the Code (relating to voting shares held by a fiduciary, in the name of a 
corporation or in joint ownership).

               The shareholders' vote may be by voice vote or by ballot; 
provided, however, that any election for directors must be by ballot if 
demanded by any shareholder at the meeting and before the voting has begun.

               Except as provided in the last paragraph of this Section 2.8, 
or as may be otherwise provided in the articles of incorporation, each 
outstanding share, regardless of class, shall be entitled to one vote on, 
each matter submitted to a vote of the shareholders.  Any shareholder 
entitled to vote on any matter may vote part of the shares in favor of the 
proposal and refrain from voting the remaining shares or, except when the 
matter is the election of directors, may vote them against the proposal; but, 
if the shareholder fails to specify the number of shares which the 
shareholder is voting affirmatively, it will be conclusively presumed that 
the shareholder's approving vote is with respect to all shares which the 
shareholder is entitled to vote.

               If a quorum is present, the affirmative vote of the majority 
of the shares represented and voting at a duly held meeting (which shares 
voting affirmatively also constitute at least a majority of the required 
quorum) shall be the act of the shareholders, unless the vote of a greater 
number or a vote by classes is required by the Code or by the articles of 
incorporation.

               At a shareholders' meeting at, which directors are to be 
elected, a shareholder shall be entitled to cumulate votes (i.e.  cast for 
any candidate a number of votes greater than the number of votes which such 
shareholder normally is entitled to cast) if the candidates' names have been 
placed in nomination prior to commencement of the voting and the shareholder 
has given notice prior to commencement of the voting of the shareholder's 
intention to cumulate votes. If any shareholder has given such a notice, then 
every shareholder entitled to vote may cumulate votes for candidates in 
nomination either (i) by giving one candidate a number of votes equal to the 
number of directors to be elected multiplied by the number of votes to which 
that shareholder's shares are normally entitled or (ii) by distributing the 
shareholder's votes on the same principle among any or all of the candidates, 
as the shareholder thinks fit. The candidates receiving the highest number of 
affirmative votes, up to the number of directors to be elected, shall be 
elected; votes against any candidate and votes withheld shall have no legal 
effect.

               2.9  VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT

               The transactions of any meeting of shareholders, either annual 
or special, however called and noticed, and wherever held, shall be as valid 
as though had at a meeting duly held after regular call and notice, if a 
quorum be present either in person or by proxy, and if, either before or 
after the meeting, each person entitled to vote, who was not present in 
person or by proxy, signs a written waiver of notice or a consent to the 
holding of the meeting or an approval of the minutes thereof.  The waiver of 
notice or consent or approval need not specify either the business

                                      -4-
<PAGE>

to be transacted or the purpose of any annual or special meeting of 
shareholders, except that if action is taken or proposed to be taken for 
approval of any of those matters specified in the second paragraph of Section 
2.4 of these bylaws, the waiver of notice or consent or approval shall state 
the general nature of the proposal.  All such waivers, consents, and 
approvals shall be filed with the corporate records or made a part of the 
minutes of the meeting.

               Attendance by a person at a meeting shall also constitute a 
waiver of notice of and presence at that meeting, except when the person 
objects at the beginning of the meeting to the transaction of any business 
because the meeting is not lawfully called or convened.  Attendance at a 
meeting is not a waiver of any right to object to the consideration of 
matters required by the Code to be included in the notice of the meeting but 
not so included, if that objection is expressly made at the meeting.

               2.10 SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

               Any action which may be taken at any annual or special meeting 
of shareholders may be taken without a meeting and without prior notice, if a 
consent in writing, setting forth the action so taken, is signed by the 
holders of outstanding shares having not less than the minimum number of 
votes that would be necessary to authorize or take that action at a meeting 
at which all shares entitled to vote on that action were present and voted.   

             In the case of election of directors, such a consent shall be 
effective only if signed by the holders of all outstanding shares entitled to 
vote for the election of directors.  However, a director may be elected at 
any time to fill any vacancy on the board of directors, provided that it was 
not created by removal of a director and that it has not been filled by the 
directors, by the written consent of the holders of a majority of the 
outstanding shares entitled to vote for the election of directors.

               All such consents shall be maintained in the corporate 
records.  Any shareholder giving a written consent, or the shareholder's 
proxy holders, or a transferee of the shares, or a personal representative of 
the shareholder, or their respective proxy holders, may revoke the consent by 
a writing received by the secretary of the corporation before written 
consents of the number of shares required to authorize the proposed action 
have been filed with the secretary.

               If the consents of all shareholders entitled to vote have not 
been solicited in writing and if the unanimous written consent of all such 
shareholders has not been received, then the secretary shall give prompt 
notice of the corporate action approved by the shareholders without a 
meeting.  Such notice shall be given to those shareholders entitled to vote 
who have not consented in writing and shall be given in the manner specified 
in Section 2.5 of these bylaws.  In the case of approval of (i) a contract or 
transaction in which a director has a direct or indirect financial interest, 
pursuant to Section 310 of the Code, (ii) indemnification of a corporate 
"agent," pursuant to Section 317 of the Code, (iii) a reorganization of the 
corporation, pursuant to Section 1201 of the Code, and (iv) a distribution in 
dissolution other than in accordance with the rights of outstanding preferred 
shares, pursuant to Section 2007 of the Code, the notice shall be given at 
least ten (10) days before the consummation of any action authorized by that 
approval.

               2.11 RECORD DATE FOR SHAREHOLDER NOTICE; VOTING; GIVING 
CONSENTS

               For purposes of determining the shareholders entitled to 
notice of any meeting or to vote thereat or entitled to give consent to 
corporate action without a meeting, the board of directors may fix, in 
advance, a record date, which shall not be more than sixty (60) days nor less 
than ten (10) days before the date of any such meeting nor more than sixty 
(60) days before any such action without a meeting, and in such event only 
shareholders of record on the date so fixed are entitled to notice and to 
vote or to give consents, as the case may be, notwithstanding any transfer of 
any shares on the books of the corporation after the record date, except as 
otherwise provided in the Code.

               If the board of directors does not so fix a record date:

                    (a)  the record date for determining shareholders 
entitled to notice of or to vote at a meeting of shareholders shall be at the 
close of business on the business day next preceding the day on which notice 
is given or, if notice is waived, at the close of business on the business 
day next preceding the day on which the meeting is held; and

                    (b)  the record date for determining shareholders 
entitled to give consent to corporate action in writing without a meeting, 
(i) when no prior action by the board has been taken, shall be the day on 
which the first written consent is given, or (ii) when prior action by the 
board has been taken, shall be at the close of business on the day on which 
the board adopts the resolution relating to that action, or the sixtieth 
(60th) day before the date of such other action, whichever is later.

               The record date for any other purpose shall be as provided in 
Article VIII of these bylaws.

               2.12 PROXIES

               Every person entitled to vote for directors, or on any other 
matter, shall have the right to do so either in person or by one or more 
agents authorized by a written proxy signed by the person and filed with the 
secretary of the corporation.  A proxy shall be deemed signed if the 
shareholder's name is placed on the proxy (whether by manual signature, 
typewriting, telegraphic transmission or otherwise) by the shareholder or the 
shareholder's attorney-in-fact.  A validly executed proxy which does not 
state that it is irrevocable shall continue in full force and effect unless 
(i) the person who executed the proxy revokes it prior to the time of voting 
by delivering a writing to the corporation stating that the proxy is revoked 
or by executing a subsequent proxy and presenting it to the meeting or by 
voting in person at the meeting, or (ii) written notice of the death or 
incapacity of the maker of that proxy is received by the corporation before 
the vote pursuant to that proxy is counted; provided, however, that no proxy 
shall be valid after the expiration of eleven (11) months from the date of 
the proxy, unless otherwise provided in the proxy.  The dates contained on 
the forms of proxy presumptively determine the order of execution, regardless 
of the postmark dates on the envelopes in which they are mailed.  The 
revocability of a proxy that states on its face that it is irrevocable shall 
be governed by the provisions of Sections 705(e) and 705(f) of the Code.

               2.13 INSPECTORS OF ELECTION

               Before any meeting of shareholders, the board of directors may 
appoint an inspector or inspectors of election to act at the meeting or its 
adjournment. If no inspector of election is so appointed, then the chairman 
of the meeting may, and on the request of any shareholder or a shareholder's 
proxy shall, appoint an inspector or inspectors of election to act at the 
meeting.  The number of inspectors shall be either one (1) or three (3).  If 
inspectors are appointed at a meeting.  pursuant to the request of one (1) or 
more shareholders or proxies, then the holders of a majority of shares or 
their proxies present at the meeting shall determine whether one (1) or three 
(3) inspectors are to be appointed.  If any person appointed as inspector 
fails to appear or fails or refuses to act, then the chairman of the meeting 
may, and upon the request of any shareholder or a shareholder's proxy shall, 
appoint a person to fill that vacancy.

               Such inspectors shall:

                    (a)  determine the number of shares outstanding and the 
voting power of each, the number of shares represented at the meeting, the 
existence of a quorum, and the authenticity, validity, and effect of proxies;

                    (b)  receive votes, ballots or consents;

                    (c)  hear and determine all challenges and questions in 
any way arising in connection with the right to vote;

                    (d)  count and tabulate all votes or consents;

                    (e)  determine when the polls shall close;

                    (f)  determine the result; and

                    (g)  do any other acts that may be proper to conduct the 
election or vote with fairness to all shareholders.

                                    ARTICLE III

               3.1  POWERS

               Subject to the provisions of the Code and any limitations in 
the articles of incorporation and these bylaws relating to action required to 
be approved by the shareholders or by the outstanding shares, the business 
and affairs of the corporation shall be managed and all corporate powers 
shall be exercised by or under the direction of the board of directors.

               3.2  NUMBER OF DIRECTORS

               The number of directors of the corporation shall be not less 
than five (5) nor more than nine (9).*  The exact number of directors shall 
be seven (7) until changed, within the limits specified above, by a bylaw 
amending this Section 3.2, duly adopted by the board of directors or by the 
shareholders.  This indefinite number may be changed, or a definite number 
may be fixed without provision for an indefinite number, by a duly adopted 
amendment to the articles of incorporation or by an amendment to this bylaw 
adopted by the vote or written consent of holders of a majority of the 
outstanding shares entitled to vote; provided, however, that an amendment 
reducing the fixed number or the minimum number of directors to a number less 
than five (5) cannot be adopted if the votes cast against its adoption at a 
meeting, or the shares not consenting in the case of an action by written 
consent, are equal to more than sixteen and two-thirds percent (16-2/3%) of 
the outstanding shares entitled to vote thereon.

               No reduction of the authorized number of directors shall have 
the effect of removing any director before that director's term of office 
expires.

               3.3  ELECTION AND TERM OF OFFICE OF DIRECTORS

               Directors shall be elected at each annual meeting of 
shareholders to hold office until the next annual meeting.  Each director, 
including a director elected to fill a vacancy, shall hold office until the 
expiration of the term for which elected and until a successor has been 
elected and qualified.

               3.4  RESIGNATION AND VACANCIES

               Any director may resign effective on giving written notice to 
the chairman of the board, the president, the secretary or the board of 
directors, unless the notice specifies a later time for that resignation to 
become effective.  If the resignation of a director is effective at a future 
time, the board of directors may elect a successor to take office when the 
resignation becomes effective.

               Vacancies in the board of directors may be filled by a 
majority of the remaining directors, even if less than a quorum, or by a sole 
remaining director; however, a vacancy created by the removal of a director 
by the vote or written consent of the shareholders or by court order may be 
filled only by the affirmative vote of a majority of the shares represented 
and voting at a duly held meeting at which a quorum is present (which shares 
voting affirmatively also constitute a majority of the required quorum) or by 
the unanimous written consent of all shares entitled to vote thereon.  Each 
director so elected shall hold office until the next annual meeting of the 
shareholders and until a successor has been elected and qualified.

directors may be taken without a meeting, provided that all members of the

settlements, and other amounts actually and reasonably incurred in connection 
with any proceeding (as defined in Section 317(a) of the Code), arising by

For purposes of this Section 6.1, a "director" or "officer" of the 
corporation includes any person (i) who is or was a director or officer of 
the corporation, (ii) who is or was serving at the request of the corporation 
as a director or officer of another corporation, partnership, joint venture, 
trust or other enterprise, or iii) who was a director, officer or employee of 
a corporation which was a predecessor corporation of the corporation or of 
another enterprise at the request of such predecessor corporation.

               6.2   INDEMNIFICATION OF OTHERS

               The corporation shall have the power, to the extent and in the 
manner permitted by the Code, to indemnify each of its employees and agents 
(other than directors and officers) against expenses (as defined in Section 
317(a) of the Code), judgments, fines, settlements, and other amounts 
actually and reasonably incurred in connection with any proceeding (as 
defined in Section 317 (a) of the Code), arising by reason of the fact that 
such person is or was an agent of the corporation.  For purposes of this 
Section 6.2, an "agent" of the corporation (other than a director or officer) 
includes any person (i) who is or was an agent of the corporation, (ii) who 
is or was serving at the request of the corporation as an agent of another 
corporation, partnership, joint venture, trust or other enterprise, or (iii) 
who was an agent of a corporation which was a predecessor corporation of the

               6.3  PAYMENT OF EXPENSES IN ADVANCE



                                     -16-
<PAGE>

               Expenses incurred in defending any civil or criminal action or 
proceeding for which indemnification is required pursuant to Section 6.1 or 
for which indemnification is permitted pursuant to Section 6.2 following 
authorization thereof by the Board of Directors shall be paid by the 
corporation in advance of the final disposition of such action or proceeding 
upon receipt of any undertaking by or on behalf of the indemnified party to 
repay such amount if it shall ultimately be determined that the indemnified 
party is not entitled to be indemnified as authorized in this Article VI.

               6.4  INDEMNITY NOT EXCLUSIVE

               The indemnification provided by this Article VI shall not be 
deemed exclusive of any other rights to which those seeking indemnification 
may be entitled under any bylaw, agreement, vote of shareholders or 
disinterested directors or otherwise, both as to action in an official 
capacity and as to action in another capacity while holding such office, to 
the extent that such additional rights to indemnification are authorized in 
the Articles of Incorporation.

               6.5  INSURANCE INDEMNIFICATION

               The corporation shall have the power to purchase and maintain 
insurance on behalf of any person who is or was a director, officer, employee

incurred by such person in such capacity or arising out of such person's 
status as such, whether or not the corporation would have the power to 
indemnify him against such liability under the provisions of this Article VI.

               6.6. CONFLICTS

               No indemnification or advance shall be made under this Article 
VI, except where such indemnification or advance is mandated by law or the 
order, judgment or decree of any court of competent jurisdiction, in any 
circumstance where it appears:

                     (1) That it would be inconsistent with a provision of 
the Articles of Incorporation, these bylaws, a resolution of the shareholders 
or an agreement in effect at the time of the accrual of the alleged cause of 
the action asserted in the proceeding in which the expenses were incurred or 
other amounts were paid, which prohibits or otherwise limits indemnification; 
or

                     (2) That it would be inconsistent with any condition 
expressly imposed by a court in approving a settlement.

               The board of directors shall cause an annual report to be sent

(100) holders of record.

               7.6  FINANCIAL STATEMENTS

corporation for the three-month, six-month or nine-month period of the then 
current fiscal year ended more than thirty (30) days before the date of the 
request, and for a balance sheet of the corporation as of the end of that 
period, then the chief financial officer shall 

                                      -19-
<PAGE>

corporation has not sent to the shareholders its annual report for the last 
fiscal year, the statements referred to in the first paragraph of this 
Section 7.6 shall likewise be delivered or mailed to the shareholder or 
shareholders within thirty (30) days after the request.

               The quarterly income statements and balance sheets referred to

                                 GENERAL MATTERS


               8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

               For purposes of determining the shareholders entitled to 
receive payment of any dividend or other distribution or allotment of any 
rights or the shareholders entitled to exercise any rights in respect of any 
other lawful action (other than action by shareholders by written consent 
without a meeting), the board of directors may fix, in advance, a record 
date, which shall not be more than sixty (60) days before any such action.  
In that case, only shareholders of record at the close of business on the 
date so fixed are entitled to receive the dividend, distribution or allotment 
of rights, or to exercise such rights, as the case may be, notwithstanding 
any transfer of any shares on the books of the corporation after the record 
date so fixed, except as otherwise provided in the Code.

               If the board of directors does not so fix a record date, then 
the record date for determining shareholders for any such purpose shall be at 
the close of business on the day on which the board adopts the applicable 
resolution or the sixtieth (60th) day before the date of that action, 
whichever is later.

               8.2  CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

               From time to time, the board of directors shall determine by 
resolution which person or persons may sign or endorse all checks, drafts, 
other orders for payment of money, notes or other evidences of indebtedness 
that are issued in the name of or payable to the corporation, and only the 
persons so authorized shall sign or endorse those instruments.

               8.3  CORPORATE CONTRACTS AND INSTRUMENTS: HOW EXECUTED

               The board of directors, except as otherwise provided in these 
bylaws, may authorize any officer or officers, or agent or agents, to enter 
into any contract or execute any instrument in the name of and on behalf of 
the corporation; such authority may be general or confined to specific 

                                      -20-
<PAGE>

instances. Unless so authorized or ratified by the board of directors or 
within the agency power of an officer, no officer, agent or employee shall 
have any power or authority to bind the corporation by any contract or 
engagement or to pledge its credit or to render it liable for any purpose or 
for any amount.

               8.4  CERTIFICATES FOR SHARES

               A certificate or certificates for shares of the corporation 
shall be issued to each shareholder when any of such shares are fully paid.  
The board of directors may authorize the issuance of certificates for shares 
partly paid provided that these certificates shall state the total amount of 
the consideration to be paid for them and the amount actually paid.  All 
certificates shall be signed in the name of the corporation by the chairman 
of the board or the vice chairman of the board or the president or a vice 
president and by the chief financial officer or an assistant treasurer or the 
secretary or an assistant secretary, certifying the number of shares and the 
class or series of shares owned by the shareholder.  Any or all of the 
signatures on the certificate may be facsimile.

               In case any officer, transfer agent or registrar who has 
signed or whose facsimile signature has been placed on a certificate ceases 
to be that officer, transfer agent or registrar before that certificate is 
issued, it may be issued by the corporation with the same effect as if that 
person were an officer, transfer agent or registrar at the date of issue.

               8.5  LOST CERTIFICATES

               Except as provided in this Section 8.5, no new certificates 
for shares shall be issued to replace a previously issued certificate unless 
the latter is surrendered to the corporation and cancelled at the same time.  
The board of directors may, in case any share certificate or certificate for 
any other security is lost, stolen or destroyed, authorize the issuance of 
replacement certificates on such terms and conditions as the board may 
require; the board may require indemnification of the corporation secured by 
a bond or other adequate security sufficient to protect the corporation 
against any claim that may be made against it, including any expense or 
liability, on account of the alleged loss, theft or destruction of the 
certificate or the issuance of the replacement certificate.

               8.6  CONSTRUCTION; DEFINITIONS

               Unless the context requires otherwise, the general provisions, 
rules of construction, and definitions in the Code shall govern the 
construction of these bylaws.  Without limiting the generality of this 
provision, the singular number includes the plural, the plural number 
includes the singular, and the term "person" includes both a corporation and 
a natural person.

               9.1  AMENDMENT BY SHAREHOLDERS

               New bylaws may be adopted or these bylaws may be amended or 
repealed by the vote or written consent of holders of a majority of the 
outstanding shares entitled to vote; provided, however, that if the articles 
of incorporation of the corporation set forth the number of authorized 
directors of the corporation, then the authorized number of directors may be 
changed only by an amendment of the articles of incorporation.

               9.2  AMENDMENT BY DIRECTORS

               Subject to the rights of the shareholders as provided in 
Section 9.1 of these bylaws, bylaws, other than a bylaw or an amendment of a 
bylaw changing the authorized number of directors (except to fix the 
authorized number of directors pursuant to a bylaw providing for a variable

                            CENTURA SOFTWARE CORPORATION
                   AMENDMENT TO PREFERRED SHARES RIGHTS AGREEMENT


     On February 17, 1998, the Board of Directors of Centura Software
Corporation (the "COMPANY") voted to amend that certain Preferred Shares Rights
Agreement dated as of August 3, 1994 (the "RIGHTS AGREEMENT") between the
Company (formerly Gupta Corporation) and Chemical Trust Company of California
(pursuant to Section 27 of the Rights Agreement), effective as of February 27,
1998, as follows:

     SECTION 1(a)  "ACQUIRING PERSON".
     
     Section 1(a) of the Rights Agreement shall be amended and restated in its
entirety to read as follows:
     
               "(a) "Acquiring Person" shall mean any Person who or
          which, together with all Affiliates and Associates of such
          Person, shall be the Beneficial Owner of 15% or more of the
          Common Shares then outstanding, but shall not include the
          Company, any Subsidiary of the Company or any employee
          benefit plan of the Company or of any Subsidiary of the
          Company, or any entity holding Common Shares for or pursuant
          to the terms of any such plan.  Notwithstanding the
          foregoing, no Person shall be deemed to be an Acquiring
          Person either (i) as the result of an acquisition of Common
          Shares by the Company which, by reducing the number of
          shares outstanding, increases the proportionate number of
          shares beneficially owned by such Person to 15% or more of
          the Common Shares of the Company then outstanding; PROVIDED,
          HOWEVER, that if a Person shall become the Beneficial Owner
          of 15% or more of the Common Shares of the Company then
          outstanding by reason of share purchases by the Company and
          shall, after such share purchases by the Company, become the
          Beneficial Owner of any additional Common Shares of the
          Company, then such Person shall be deemed to be an Acquiring
          Person, or (ii) if within eight days after such Person would
          otherwise become an Acquiring Person (but for the operation
          of this clause (ii)), such Person notifies the Board of
          Directors that such Person did so inadvertently and within
          two days after such notification, such Person is the
          Beneficial Owner of less than 15% of the outstanding Common
          Shares.  Notwithstanding the foregoing: (i) Umang P. Gupta
          ("Gupta") shall not be considered an "Acquiring Person" as a
          result of being, at any date, the Beneficial Owner of that
          number of Common Shares which he currently beneficially owns
          or which he is permitted or required to purchase on or
          before such date in accordance with the provisions of any
          plan, arrangement, agreement or transaction 

<PAGE>

          approved by the Board of Directors of the Company or any 
          committee of the Board of Directors; PROVIDED, HOWEVER, 
          that if Gupta shall, after the date hereof, become the 
          Beneficial Owner of any Common Shares other than 
          pursuant to a plan, arrangement, agreement or transaction 
          approved by the Board of Directors of the Company or any 
          committee of the Board of Directors, then, if Gupta 
          would otherwise be an Acquiring Person, he shall be 
          deemed to be an Acquiring Person and all Common Shares 
          then beneficially owned by Gupta shall be counted for 
          purposes of determining whether Gupta is an Acquiring 
          Person; and (ii) neither Newport Acquisition Company No. 
          2, LLC ("NAC"), nor any of the Persons listed on Annex I 
          attached hereto (collectively, the "Approved Persons") 
          shall be considered an "Acquiring Person" as a result of 
          (i) the purchase from Computer Associates International, 
          Inc. by NAC of that certain Floating Rate Convertible 
          Subordinated Note Due 1998 dated as of April 3, 1995 in 
          the principal amount of $10,000,000 (the "Note"), (ii) 
          the conversion of the Note by NAC into 11,415,094 shares 
          of Common Stock of the Company (the "Conversion Shares") 
          pursuant to a Note Conversion Agreement between the 
          Company and NAC dated February 27, 1998 or (iii) any of 
          such Approved Persons becoming the Beneficial Owner of 
          additional Common Shares of the Company up to but not 
          exceeding 14.99% of the Common Shares then outstanding, 
          but not including in either the numerator or denominator 
          for purposes of such percentage calculation any of the 
          Conversion Shares."

      SECTION 1(g)  "CONTINUING DIRECTOR".


      Section 1(g) of the Rights Agreement shall be amended and restated
in its entirety to read as follows:

               "(g) "Continuing Director" shall mean (i) any member of
          the Board of Directors of the Company, while a member of the
          Board, who is not an Acquiring Person, or an Affiliate or
          Associate of an Acquiring Person, or a representative of an
          Acquiring Person or of any such Affiliate or Associate, and
          who was a member of the Board prior to the date of this
          Agreement, or (ii) any Person who subsequently becomes a
          member of the Board, while a member of the Board, who is not
          an Acquiring Person, or an Affiliate or Associate of an
          Acquiring Person, or a representative of an Acquiring Person
          or of any such Affiliate or Associate, if such Person's
          nomination for election or election to the Board is
          recommended or approved by a majority of the Continuing

          Directors; or (iii) any Person nominated to the Board of
          Directors by NAC."

The undersigned, being the duly appointed Secretary of Centura Software
Corporation, does hereby certify that the Rights Agreement was amended as set
forth above effective as of February 27, 1998.

Board of Directors

RE: HICKEY & HILL, INC. MANAGEMENT CONTRACT

Gentlemen:

This letter sets out the terms and conditions upon which HICKEY & HILL, INC. 
("H&H") would be engaged to provide management services to Centura Software 
Corporation ("Centura" or the "Company"). Furthermore, it is our 
understanding that the Board is in agreement with the general terms and 
conditions of this effort and that the Company has the approvals necessary to 
execute this agreement. We are prepared to undertake this engagement per the 
following:

SERVICES

     Services to be provided would be at the direction of the Company's Board 
     of Directors. At present it is contemplated that such services would 
     include the following:

        - Performing duties of the Chief Executive Officer, Chief Financial 
          Officer and the principal marketing officer during the engagement, 
          as appropriate. Such duties will be performed initially by Scott 
          Broomfield, John Bowman and Kathy Lane, respectively. During the 
          month of November, 1997, however, the positions being filed are 
          that of the Chief Operations Officer, V.P. of Finance and the 
          principal marketing officer.

        - Development and implementation of a plan to improve shareholder 
          value, through development and implementation of an updated 
          business plan, subject to the Company's Board of Directors.

        - Assist the Board of Directors in execution of Progress Software's 
          ("Progress") acquisition interest. Our understanding is that 
          Progress will deliver a letter of intent, or equivalent by December 
          1, 1997.

     The initial term of this engagement will extend through December 31, 
     1999. Moreover, this engagement may be terminated by either party upon 
     90 days prior written notice. In the event of termination, the Options 
     will continue to vest monthly for an additional 90 days (monthly basis) 
     after written notice.

COMPENSATION

     H&H would be compensated as follows:

     A. $70,000 per month for the first two months, $50,000 per month 
     thereafter. The monthly fee will be due and payable in advance on the 
     first day of each month. Reimbursable business expenses will be due upon 
     presentation of an invoice. Further, the Company will pay H&H an 
     additional $25,000 for work performed during the second half of October, 
     1997.

     B. Non-statutory stock options to purchase 1,500,000 shares of common 
     stock of the Company at a price equal to the closing price on the NASDAQ 
     stock market on the day prior to the signing of this contract, to be 
     issued pursuant to a Company stock option plan (the "Options") approved 
     and duly adopted by the Board of Directors of the Company, but not 
     subject to shareholder approval (unless otherwise required by the 
     NASDAQ). Such Options, unless the Progress acquisition occurs, will vest 
     in increments of 25% every six months after commencement of the 
     engagement, with an accelerated vesting in the event of a "Change of 
     Control" (defined in Section E below).

     C. In the event that Progress enters into a letter of intent or 
     memorandum of understanding by December 1, 1997 to acquire the Company 
     and H&H is involved in the running of the business, then the Options 
     will vest monthly beginning November 1, 1997 (at the beginning of the 
     month -- 62,500 shares / month), plus the monthly cash compensation as 
     defined above in Section A.

     D. Reimbursement of all reasonable business expenses.

     E. As used above in Section B., "Change of Control" shall mean any of 
     the following events, subject to a Progress carve out:

        - All or substantially all of the assets of the Company are sold, 
          exchanged or otherwise transferred in one or more transactions;
        - The Company is merged or consolidated with or into another 
          corporation with the effect that the common stockholders with the 
          effect that the common stockholders immediately prior to such 
          merger or consolidation hold less than 75% of the ordinary voting 
          power of the outstanding securities of the 


                                       2


<PAGE>

          surviving corporation of such merger or the corporation resulting 
          from such consolidation;
        - A person or group (such as term is used in rule 13d-5 under the 
          Securities and Exchange Act of 1934) shall, as a result of the 
          tender or exchange offer, open market purchases, merger, private 
          placement or otherwise, have become, directly or indirectly, the 
          beneficial owner (within the meaning of the rule 13d-5 under the 
          Securities and Exchange Act of 1934) or securities having 25% or 
          more of the voting power of then outstanding securities of the 
          Company.

ADMINISTRATIVE MATTERS

     1. The Company grants to H&H permission to participate in discussions, 
     on the Company's behalf, with third parties and disclose such 
     information which, in H&H's sole discretion, is considered appropriate. 
     Any of the H&H representatives may be involved with these discussions. 
     The Company further agrees that all written materials and documents 
     prepared by or gathered by H&H are, or become, the property of H&H.

     2. H&H makes no representation nor can offer any assurance that the 
     Company can, in fact, become or remain profitable or that the means 
     required in that attempt will be acceptable to the Company. H&H would 
     commit its best effort and experience in this engagement, but it can

                          CENTURA SOFTWARE CORPORATION
 
                      NONSTATUTORY STOCK OPTION AGREEMENT
 
    1.  GRANT OF OPTION.  Centura Software Corporation, a California corporation
(the "COMPANY"), hereby grants to the Optionee named in the Notice of Stock
Option Grant attached to this Agreement ("OPTIONEE"), an option (the "OPTION")
to purchase the total number of shares of Common Stock (the "SHARES") set forth
in the Notice of Stock Option Grant, at the exercise price per share set forth
in the Notice of Stock Option Grant (the "EXERCISE PRICE") subject to the terms,
definitions and provisions of this Nonstatutory Stock Option Agreement (the
"Agreement").
 
    This Option is intended to be a Nonstatutory Stock Option.
 
    2.  EXERCISE OF OPTION.  This Option shall be exercisable during its term in
accordance with the Vesting Schedule set out in the Notice of Stock Option Grant
as follows:
 
        (a) RIGHT TO EXERCISE.
 
            (i) This Option may not be exercised for a fraction of a share.
 
            (ii) In the event of Optionee's death, disability or other
       termination of employment, the exercisability of the Option is governed
       by Sections 6, 7 and 8 below, subject to the limitations contained in
       paragraph (iii) below.
 
           (iii) In no event may this Option be exercised after the date of
       expiration of the term of this Option as set forth in the Notice of Stock
       Option Grant.
 
        (b) METHOD OF EXERCISE.
 
            (i) This Option shall be exercisable by delivering to the Company a
       written notice of exercise (in the form attached as EXHIBIT A) which
       shall state the election to exercise the Option, the number of Shares in
       respect of which the Option is being exercised, and such other
       representations and agreements as to the holder's investment intent with
       respect to such Shares of Common Stock as may be required by the Company.
       Such written notice shall be signed by Optionee and shall be delivered in
       person or by certified mail to the Secretary of the Company. The written
       notice shall be accompanied by payment of the Exercise Price. This Option
       shall be deemed to be exercised upon receipt by the Company of such
       written notice accompanied by the Exercise Price.
 
            (ii) As a condition to the exercise of this Option, Optionee agrees
       to make adequate provision for federal, state or other tax withholding
       obligations, if any, which arise upon the exercise of the Option or
       disposition of Shares, whether by withholding, direct payment to the
       Company, or otherwise.
 
           (iii) No Shares will be issued pursuant to the exercise of an Option
       unless such issuance and such exercise shall comply with all relevant
       provisions of law and the requirements of any stock exchange upon which
       the Shares may then be listed. Assuming such compliance, for income tax
       purposes the Shares shall be considered transferred to Optionee on the
       date on which the Option is exercised with respect to such Shares.
 
    3.  OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), at the time this
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.
 
                                       1
<PAGE>
    4.  METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of the
following, or a combination of the following, at the election of Optionee: (a)
cash; (b) check; (c) surrender of other Shares of Common Stock of the Company
that (i) either have been owned by Optionee for more than six (6) months on the
date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.
 
    5.  RESTRICTIONS ON EXERCISE.  This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("REGULATION G") as
promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option, the Company may require Optionee to make any representation and warranty
to the Company as may be required by any applicable law or regulation.
 
    6.  TERMINATION OF RELATIONSHIP.  In the event of termination of Optionee's
employment or consulting relationship with the Company, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "TERMINATION
DATE"), exercise this Option during the Termination Period set out in the Notice
of Stock Option Grant. To the extent that Optionee was not entitled to exercise
this Option at the date of such termination, or if Optionee does not exercise
this Option within the time specified in the Notice of Stock Option Grant, the
Option shall terminate.
 
    7.  DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of Optionee's employment or consulting
relationship with the Company as a result of total and permanent disability (as
defined in Section 22(e)(3) of the Internal Revenue Code), Optionee may, but
only within five (5) years from the date of termination of such relationship
(but in no event later than the date of expiration of the term of this Option as
set forth in Section 10 below), exercise the Option to the extent otherwise so
entitled at the date of such termination. To the extent that Optionee was not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified in this Agreement, the Option shall terminate.
 
    8.  DEATH OF OPTIONEE.  In the event of the death of Optionee:
 
        (a) during the term of this Option and while an employee or consultant
    of the Company and having been an employee or consultant of the Company
    since the date of grant of the Option, the Option may be exercised, at any
    time within five (5) years following the date of death (but in no event
    later than the date of expiration of the term of this Option as set forth in
    Section 10 below), by Optionee's estate or by a person who acquired the
    right to exercise the Option by bequest or inheritance, including by an 
    officer of High Technology Capital Management, but only to the
    extent of the right to exercise that would have accrued had Optionee
    continued living and remained as an employee of the Company three (3) months
    after the date of death; or
 
        (b) within thirty (30) days after the termination of Optionee's
    employment or consulting relationship with the Company, the Option may be
    exercised, at any time within five (5) years following the date of death
    (but in no event later than the date of expiration of the term of this
    Option as set forth in Section 10 below), by Optionee's estate or by a
    person who acquired the right to exercise the Option by bequest or
    inheritance, but only to the extent of the right to exercise that had
    accrued at the date of termination.
 
                                       2
<PAGE>
    9.  NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution. The
designation of a beneficiary does not constitute a transfer. An Option may be
exercised during the lifetime of Optionee only by Optionee or a transferee
permitted by this section. The terms of this Option shall be binding upon the
executors, administrators, heirs, successors and assigns of Optionee.
 
    10. TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the terms of this Option.
 
    11. NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees that
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an employee or consultant of the Company at the will of the
Company (not through the act of being hired, being granted this Option or
acquiring Shares under this Agreement). Optionee further acknowledges and agrees
that nothing in this Agreement shall confer upon Optionee any right with respect
to continuation as an employee or consultant of the Company, nor shall it
interfere in any way with his or her right or the Company's right to terminate
his or her employment or consulting relationship at any time, with or without
cause.
 
    12. TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant. OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE, AND
THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT HIS
OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.
 
        (a) EXERCISE OF NONSTATUTORY STOCK OPTION.  Optionee may incur regular
    federal income tax liability upon the exercise of the Option. Optionee will
    be treated as having received compensation income (taxable at ordinary
    income tax rates) equal to the excess, if any, of the fair market value of
    the Shares on the date of exercise over the Exercise Price. In addition, if
    Optionee is an employee of the Company, the Company will be required to
    withhold from Optionee's compensation or collect from Optionee and pay to
    the applicable taxing authorities an amount equal to a percentage of this
    compensation income at the time of exercise.
 
        (b) DISPOSITION OF SHARES.  Gain realized on the disposition of Shares
    will be treated as long-term or short-term capital gain depending on whether
    or not the disposition occurs more than one year after the exercise date.
 
    13. SIGNATURE.  This Stock Option Agreement shall be deemed executed by the
Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

                      NONSTATUTORY STOCK OPTION AGREEMENT
 
    1.  GRANT OF OPTION.  Centura Software Corporation, a California corporation
(the "COMPANY"), hereby grants to the Optionee named in the Notice of Stock
Option Grant attached to this Agreement ("OPTIONEE"), an option (the "OPTION")
to purchase the total number of shares of Common Stock (the "SHARES") set forth
in the Notice of Stock Option Grant, at the exercise price per share set forth
in the Notice of Stock Option Grant (the "EXERCISE PRICE") subject to the terms,
definitions and provisions of this Nonstatutory Stock Option Agreement (the
"Agreement").
 
    This Option is intended to be a Nonstatutory Stock Option.
 
    2.  EXERCISE OF OPTION.  This Option shall be exercisable during its term in
accordance with the Vesting Schedule set out in the Notice of Stock Option Grant
as follows:
 
        (a) RIGHT TO EXERCISE.
 
            (i) This Option may not be exercised for a fraction of a share.
 
            (ii) In the event of Optionee's death, disability or other
       termination of employment, the exercisability of the Option is governed
       by Sections 6, 7 and 8 below, subject to the limitations contained in
       paragraph (iii) below.
 
           (iii) In no event may this Option be exercised after the date of
       expiration of the term of this Option as set forth in the Notice of Stock
       Option Grant.
 
        (b) METHOD OF EXERCISE.
 
            (i) This Option shall be exercisable by delivering to the Company a
       written notice of exercise (in the form attached as EXHIBIT A) which
       shall state the election to exercise the Option, the number of Shares in
       respect of which the Option is being exercised, and such other
       representations and agreements as to the holder's investment intent with
       respect to such Shares of Common Stock as may be required by the Company.
       Such written notice shall be signed by Optionee and shall be delivered in
       person or by certified mail to the Secretary of the Company. The written
       notice shall be accompanied by payment of the Exercise Price. This Option
       shall be deemed to be exercised upon receipt by the Company of such
       written notice accompanied by the Exercise Price.
 
            (ii) As a condition to the exercise of this Option, Optionee agrees
       to make adequate provision for federal, state or other tax withholding
       obligations, if any, which arise upon the exercise of the Option or
       disposition of Shares, whether by withholding, direct payment to the
       Company, or otherwise.
 
           (iii) No Shares will be issued pursuant to the exercise of an Option
       unless such issuance and such exercise shall comply with all relevant
       provisions of law and the requirements of any stock exchange upon which
       the Shares may then be listed. Assuming such compliance, for income tax
       purposes the Shares shall be considered transferred to Optionee on the
       date on which the Option is exercised with respect to such Shares.
 
    3.  OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), at the time this
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.
 
                                       1
<PAGE>
    4.  METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of the
following, or a combination of the following, at the election of Optionee: (a)
cash; (b) check; (c) surrender of other Shares of Common Stock of the Company
that (i) either have been owned by Optionee for more than six (6) months on the
date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.
 
    5.  RESTRICTIONS ON EXERCISE.  This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("REGULATION G") as
promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option, the Company may require Optionee to make any representation and warranty
to the Company as may be required by any applicable law or regulation.
 
    6.  TERMINATION OF RELATIONSHIP.  In the event of termination of Optionee's
employment or consulting relationship with the Company, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "TERMINATION
DATE"), exercise this Option during the Termination Period set out in the Notice
of Stock Option Grant. To the extent that Optionee was not entitled to exercise
this Option at the date of such termination, or if Optionee does not exercise
this Option within the time specified in the Notice of Stock Option Grant, the
Option shall terminate.
 
    7.  DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of Optionee's employment or consulting
relationship with the Company as a result of total and permanent disability (as
defined in Section 22(e)(3) of the Internal Revenue Code), Optionee may, but
only within five (5) years from the date of termination of such relationship
(but in no event later than the date of expiration of the term of this Option as
set forth in Section 10 below), exercise the Option to the extent otherwise so
entitled at the date of such termination. To the extent that Optionee was not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified in this Agreement, the Option shall terminate.
 
    8.  DEATH OF OPTIONEE.  In the event of the death of Optionee:
 
        (a) during the term of this Option and while an employee or consultant
    of the Company and having been an employee or consultant of the Company
    since the date of grant of the Option, the Option may be exercised, at any
    time within five (5) years following the date of death (but in no event
    later than the date of expiration of the term of this Option as set forth in
    Section 10 below), by Optionee's estate or by a person who acquired the
    right to exercise the Option by bequest or inheritance, but only to the
    extent of the right to exercise that would have accrued had Optionee
    continued living and remained as an employee of the Company three (3) months
    after the date of death; or
 
        (b) within thirty (30) days after the termination of Optionee's
    employment or consulting relationship with the Company, the Option may be
    exercised, at any time within five (5) years following the date of death
    (but in no event later than the date of expiration of the term of this
    Option as set forth in Section 10 below), by Optionee's estate or by a
    person who acquired the right to exercise the Option by bequest or
    inheritance, but only to the extent of the right to exercise that had
    accrued at the date of termination.

    9.  NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution. The
designation of a beneficiary does not constitute a transfer. An Option may be
exercised during the lifetime of Optionee only by Optionee or a transferee
permitted by this section. The terms of this Option shall be binding upon the
executors, administrators, heirs, successors and assigns of Optionee.
 
    10. TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the terms of this Option.
 
    11. NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees that
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an employee or consultant of the Company at the will of the
Company (not through the act of being hired, being granted this Option or
acquiring Shares under this Agreement). Optionee further acknowledges and agrees
that nothing in this Agreement shall confer upon Optionee any right with respect
to continuation as an employee or consultant of the Company, nor shall it
interfere in any way with his or her right or the Company's right to terminate
his or her employment or consulting relationship at any time, with or without
cause.
 
    12. TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant. OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE, AND
THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT HIS
OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.
 
        (a) EXERCISE OF NONSTATUTORY STOCK OPTION.  Optionee may incur regular
    federal income tax liability upon the exercise of the Option. Optionee will
    be treated as having received compensation income (taxable at ordinary
    income tax rates) equal to the excess, if any, of the fair market value of
    the Shares on the date of exercise over the Exercise Price. In addition, if
    Optionee is an employee of the Company, the Company will be required to
    withhold from Optionee's compensation or collect from Optionee and pay to
    the applicable taxing authorities an amount equal to a percentage of this
    compensation income at the time of exercise.
 
        (b) DISPOSITION OF SHARES.  Gain realized on the disposition of Shares
    will be treated as long-term or short-term capital gain depending on whether
    or not the disposition occurs more than one year after the exercise date.
 
    13. SIGNATURE.  This Stock Option Agreement shall be deemed executed by the
Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

                      NONSTATUTORY STOCK OPTION AGREEMENT
 
    1.  GRANT OF OPTION.  Centura Software Corporation, a California corporation
(the "COMPANY"), hereby grants to the Optionee named in the Notice of Stock
Option Grant attached to this Agreement ("OPTIONEE"), an option (the "OPTION")
to purchase the total number of shares of Common Stock (the "SHARES") set forth
in the Notice of Stock Option Grant, at the exercise price per share set forth
in the Notice of Stock Option Grant (the "EXERCISE PRICE") subject to the terms,
definitions and provisions of this Nonstatutory Stock Option Agreement (the
"Agreement").
 
    This Option is intended to be a Nonstatutory Stock Option.
 
    2.  EXERCISE OF OPTION.  This Option shall be exercisable during its term in
accordance with the Vesting Schedule set out in the Notice of Stock Option Grant
as follows:
 
        (a) RIGHT TO EXERCISE.
 
            (i) This Option may not be exercised for a fraction of a share.
 
            (ii) In the event of Optionee's death, disability or other
       termination of employment, the exercisability of the Option is governed
       by Sections 6, 7 and 8 below, subject to the limitations contained in
       paragraph (iii) below.
 
           (iii) In no event may this Option be exercised after the date of
       expiration of the term of this Option as set forth in the Notice of Stock
       Option Grant.
 
        (b) METHOD OF EXERCISE.
 
            (i) This Option shall be exercisable by delivering to the Company a
       written notice of exercise (in the form attached as EXHIBIT A) which
       shall state the election to exercise the Option, the number of Shares in
       respect of which the Option is being exercised, and such other
       representations and agreements as to the holder's investment intent with
       respect to such Shares of Common Stock as may be required by the Company.
       Such written notice shall be signed by Optionee and shall be delivered in
       person or by certified mail to the Secretary of the Company. The written
       notice shall be accompanied by payment of the Exercise Price. This Option
       shall be deemed to be exercised upon receipt by the Company of such
       written notice accompanied by the Exercise Price.
 
            (ii) As a condition to the exercise of this Option, Optionee agrees
       to make adequate provision for federal, state or other tax withholding
       obligations, if any, which arise upon the exercise of the Option or
       disposition of Shares, whether by withholding, direct payment to the
       Company, or otherwise.
 
           (iii) No Shares will be issued pursuant to the exercise of an Option
       unless such issuance and such exercise shall comply with all relevant
       provisions of law and the requirements of any stock exchange upon which
       the Shares may then be listed. Assuming such compliance, for income tax
       purposes the Shares shall be considered transferred to Optionee on the
       date on which the Option is exercised with respect to such Shares.
 
    3.  OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), at the time this
Option is exercised, Optionee shall, if required by the Company, concurrently
with the exercise of all or any portion of this Option, deliver to the Company
an investment representation statement in customary form, a copy of which is
available for Optionee's review from the Company upon request.
 
                                       1
<PAGE>
    4.  METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of the
following, or a combination of the following, at the election of Optionee: (a)
cash; (b) check; (c) surrender of other Shares of Common Stock of the Company
that (i) either have been owned by Optionee for more than six (6) months on the
date of surrender or were not acquired, directly or indirectly, from the
Company, and (ii) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised; (d) authorization from the Company to retain from the total number of
Shares as to which the Option is exercised that number of Shares having a Fair
Market value on the date of exercise equal to the exercise price for the total
number of Shares as to which the Option is exercised; or (e) if there is a
public market for the Shares and they are registered under the Securities Act,
delivery of a properly executed exercise notice together with irrevocable
instructions to a broker to deliver promptly to the Company the amount of sale
or loan proceeds required to pay the exercise price.
 
    5.  RESTRICTIONS ON EXERCISE.  This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations ("REGULATION G") as
promulgated by the Federal Reserve Board. As a condition to the exercise of this
Option, the Company may require Optionee to make any representation and warranty
to the Company as may be required by any applicable law or regulation.
 
    6.  TERMINATION OF RELATIONSHIP.  In the event of termination of Optionee's
employment or consulting relationship with the Company, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "TERMINATION
DATE"), exercise this Option during the Termination Period set out in the Notice
of Stock Option Grant. To the extent that Optionee was not entitled to exercise
this Option at the date of such termination, or if Optionee does not exercise
this Option within the time specified in the Notice of Stock Option Grant, the
Option shall terminate.
 
    7.  DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6
above, in the event of termination of Optionee's employment or consulting
relationship with the Company as a result of total and permanent disability (as
defined in Section 22(e)(3) of the Internal Revenue Code), Optionee may, but
only within five (5) years from the date of termination of such relationship
(but in no event later than the date of expiration of the term of this Option as
set forth in Section 10 below), exercise the Option to the extent otherwise so
entitled at the date of such termination. To the extent that Optionee was not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option (to the extent otherwise so entitled) within the time
specified in this Agreement, the Option shall terminate.
 
    8.  DEATH OF OPTIONEE.  In the event of the death of Optionee:
 
        (a) during the term of this Option and while an employee or consultant
    of the Company and having been an employee or consultant of the Company
    since the date of grant of the Option, the Option may be exercised, at any
    time within five (5) years following the date of death (but in no event
    later than the date of expiration of the term of this Option as set forth in
    Section 10 below), by Optionee's estate or by a person who acquired the
    right to exercise the Option by bequest or inheritance, but only to the
    extent of the right to exercise that would have accrued had Optionee
    continued living and remained as an employee of the Company three (3) months
    after the date of death; or
 
        (b) within thirty (30) days after the termination of Optionee's
    employment or consulting relationship with the Company, the Option may be
    exercised, at any time within five (5) years following the date of death
    (but in no event later than the date of expiration of the term of this
    Option as set forth in Section 10 below), by Optionee's estate or by a
    person who acquired the right to exercise the Option by bequest or
    inheritance, but only to the extent of the right to exercise that had
    accrued at the date of termination.
 
                                       2
<PAGE>
    9.  NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution. The
designation of a beneficiary does not constitute a transfer. An Option may be
exercised during the lifetime of Optionee only by Optionee or a transferee
permitted by this section. The terms of this Option shall be binding upon the
executors, administrators, heirs, successors and assigns of Optionee.
 
    10. TERM OF OPTION.  This Option may be exercised only within the term set
out in the Notice of Stock Option Grant, and may be exercised during such term
only in accordance with the terms of this Option.
 
    11. NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees that
the vesting of Shares pursuant to the Vesting Schedule is earned only by
continuing as an employee or consultant of the Company at the will of the
Company (not through the act of being hired, being granted this Option or
acquiring Shares under this Agreement). Optionee further acknowledges and agrees
that nothing in this Agreement shall confer upon Optionee any right with respect
to continuation as an employee or consultant of the Company, nor shall it
interfere in any way with his or her right or the Company's right to terminate
his or her employment or consulting relationship at any time, with or without
cause.
 
    12. TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the
brief summary set forth below of certain federal tax consequences of exercise of
this Option and disposition of the Shares under the law in effect as of the date
of grant. OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY INCOMPLETE, AND
THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT HIS
OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.
 
        (a) EXERCISE OF NONSTATUTORY STOCK OPTION.  Optionee may incur regular
    federal income tax liability upon the exercise of the Option. Optionee will
    be treated as having received compensation income (taxable at ordinary
    income tax rates) equal to the excess, if any, of the fair market value of
    the Shares on the date of exercise over the Exercise Price. In addition, if
    Optionee is an employee of the Company, the Company will be required to
    withhold from Optionee's compensation or collect from Optionee and pay to
    the applicable taxing authorities an amount equal to a percentage of this
    compensation income at the time of exercise.
 
        (b) DISPOSITION OF SHARES.  Gain realized on the disposition of Shares
    will be treated as long-term or short-term capital gain depending on whether
    or not the disposition occurs more than one year after the exercise date.
 
    13. SIGNATURE.  This Stock Option Agreement shall be deemed executed by the
Company and Optionee upon execution by such parties of the Notice of Stock
Option Grant attached to this Stock Option Agreement.

                         CENTURA SOFTWARE CORPORATION
                   SETTLEMENT AGREEMENT AND MUTUAL RELEASE

    This Settlement Agreement and Mutual Release ("AGREEMENT") is made by and 
between Centura Software Corporation, a California corporation (the 
"COMPANY"), and Samuel M. Inman ("MR. INMAN").

    WHEREAS, Mr. Inman is employed by the Company; and 

    WHEREAS, the Company and Mr. Inman have mutually agreed to terminate the 
existing employment relationship and to release each other from any claims 
arising from or related to the employment relationship.

    NOW, THEREFORE, in consideration of the mutual promises made herein, the 
Company and Mr. Inman (collectively referred to as the "PARTIES") hereby 
agree as follows:

    1.   RESIGNATION.   Mr. Inman and the Company agree that Mr. Inman's 
status as President, Chief Executive Officer and Chairman of the Board of 
Directors of the Company and all other positions of the Company held by Mr. 
Inman shall terminate on December 8, 1997, provided, however, that Mr. 
Inman's employment with the Company shall continue beyond the termination of 
such status as provided in this Agreement; and provided further than Mr. 
Inman shall remain a Director of the Company until Mr. Inman resigns such 
position or is requested to resign by the Company's Board of Directors, at 
which time Mr. Inman agrees to resign such position.

    2.   CONTINUATION OF EMPLOYMENT.   In consideration for the release of 
claims by Mr. Inman set forth below and other obligations under this 
Agreement, the Company and Mr. Inman agree to the following terms with 
respect to continuation of Mr. Inman's employment by the Company:

         (a)  that Mr. Inman shall continue to work as a full-time employee 
of the Company until December 31, 1997 (the "Termination Date"), and shall be 
entitled to receive his current base salary and any earned but unpaid bonus 
and accrued vacation (less applicable withholding) through December 31, 1997 
in accordance with the Company's regular payroll practices while so employed; 
and

         (b)  that as a condition to Mr. Inman's continued employment with 
the Company, during the period commencing on January 1, 1998 and continuing 
through July 31, 1998 (the "Service Period"), Mr. Inman agrees to provide 
services to the Company as follows: 

              (i)       Mr. Inman shall be available to assist the President, 
or other employees of the Company as designated by the President, in 
fulfilling such projects reasonably consistent with Mr. Inman's prior 
position with the Company as requested by the President;

<PAGE>

              (ii)      Mr. Inman shall report directly to the President of 
the Company; and

              (iii)     Mr. Inman shall contact the President no less 
frequently than monthly, at a day and time each month mutually agreed to by 
Mr. Inman and the President, to report the status of Mr. Inman's continuing 
projects for the Company.

To facilitate Mr. Inman's rendering of services to the Company, as set forth 
above, during the Service Period, the Company agrees to maintain Mr. Inman's 
electronic mail addresses on the Company's systems. Mr. Inman hereby 
acknowledges and agrees that the performance of his services is on an at-will 
basis, and that his services may be terminated at any time for any reason by 
the Company or Mr. Inman upon ten (10) days' written notice.

    3.   PAYMENT.  In consideration for the release of claims set forth below 
and Mr. Inman's continued services to the Company during the Service Period, 
the Company agrees to pay Mr. Inman a lump sum payment of $233,333.33, which 
is equal to seven months of current base salary (less applicable tax 
withholding), on or about January 5, 1998, the first business day of the 
Service Period.

    4.   EMPLOYEE BENEFITS.  

         (a)  Mr. Inman shall continue to receive the Company's life, 
medical, dental and vision insurance benefits at Company expense until the 
earlier of July 31, 1998 or the date on which Mr. Inman commences full or 
part-time employment with a new employer, which date shall be the "qualifying 
event" date under the Consolidated Omnibus Budget Reconciliation Act of 1985, 
as amended ("COBRA").  Following such date, Mr. Inman shall have the right to 
continue, at his own expense, coverage under the Company's medical, dental 
and vision (but not life) insurance programs as provided by COBRA.

         (b)  Except as otherwise provided above, Mr. Inman shall not be 
entitled to participate in any of the Company's benefit plans or programs 
offered to employees or officers of the Company, including, but not limited 
to, any accrual of vacation, after the Termination Date.

    5.   STOCK OPTIONS. Under the terms of the Stock Option Agreements issued 
to Mr. Inman over the course of his employment with the Company, Mr. Inman 
was granted options to purchase 479,999 (the "January 1996 Options"), and 
120,000 (the "March 1997 Option") total shares of the Company's Common Stock 
under the Company's 1986 Stock Option Plan and 1995 Stock Option Plan, 
respectively.  The January 1996 Options and the March 1997 Option may 
hereinafter be referred to collectively as the Options.  As of the 
Termination Date, 260,000 shares under the January 1996 Options and 0 shares 
under the March 1997 Option have vested, respectively (the "Vested Shares") 
and 219,999 and 120,000 shares, respectively, have not vested (the "Unvested 
Shares").  Subject to the provisions set forth in the next sentence, in 
consideration for the release of claims set forth below and for Mr. Inman's 
continued services to the Company during the Service Period, as well as other 
obligations under this Agreement, the Options shall continue to vest at their 
regular monthly vesting rate during the Service Period or so long as Mr. 
Inman serves as a member of the Board, and such Options shall thereafter
be 

                                       -2-

<PAGE>

exercisable with respect to such fully vested option shares for 30 days 
after the later of the date on which Mr. Inman ceases to provide services to 
the Company in accordance with Section 2(b) above or ceases to serve as a 
director of the Company, but no later than 30 days after July 31, 1998.  The 
foregoing provision shall be null and void and of no force or effect if:  (i) 
in the opinion of the Company's independent auditors, such continued vesting 
would require the Company to recognize an additional compensation expense to 
its income statement for the fiscal year ending December 31, 1997 or 1998, or 
(ii) if it is determined by the Board of Directors, upon consultation with 
the Company's management and independent auditors, that such continued 
vesting would preclude accounting for any proposed business combination of 
the Company as a pooling of interests, and the Board otherwise desires to 
approve such a proposed business transaction which requires as a condition to 
the closing of such transaction that it be accounted for as a pooling of 
interests.  

    Mr. Inman acknowledges and agrees that if the Options are not exercised 
within 90 days of the Termination Date, they shall no longer qualify as 
incentive stock options within the meaning of Section 422 of the Internal 
Revenue Code of 1986, as amended, and shall thereafter be nonstatutory stock 
options.  Mr. Inman further acknowledges and agrees that he shall remain 
bound by all other terms of the Stock Option Agreements issued by the Company 
to him.

    6.   NO OTHER PAYMENTS DUE.   The Company agrees that it will continue to 
pay to Mr. Inman the salary described in Section 2(a) through the Termination 
Date in accordance with the Company's normal payroll practices, and that the 
Company will pay to Mr. Inman on or before the Termination Date all salary as 
may then be due to Mr. Inman.  Mr. Inman will execute an acknowledgment of 
receipt of all such payments as received and an acknowledgment that, in light 
of the payment by the Company of all wages due, or to become due to Mr. 
Inman, California Labor Code Section 206.5 is not applicable to the Parties 
hereto. That section provides in pertinent part as follows:

              No employer shall require the execution of any release of any 
              claim or right on account of wages due, or to become due, or 
              made as an advance on wages to be earned, unless payment of 
              such wages has been made.

    7.   RELEASE OF CLAIMS.  In consideration for the obligations of both 
parties set forth in this Agreement, Mr. Inman and the Company, on behalf of 
themselves, and their respective heirs, executors, officers, directors, 
employees, investors, stockholders, administrators and assigns, hereby fully 
and forever release each other and their respective heirs, executors, 
officers, directors, employees, investors, stockholders, administrators and 
assigns, of and from any claim, duty, obligation or cause of action relating 
to any matters of any kind, whether presently known or unknown, suspected or 
unsuspected, that any of them may possess arising from any omissions, acts or 
facts that have occurred up until and including the date of this Agreement 
including, without limitation:

         (a)  any and all claims relating to or arising from Mr. Inman's 
employment relationship with the Company and the termination of that 
relationship;


                                       -3-

<PAGE>

         (b)  any and all claims relating to, or arising from, Mr. Inman's 
right to purchase, or actual purchase of shares of stock of the Company;

         (c)  any and all claims for wrongful discharge of employment; breach 
of contract, both express and implied; breach of a covenant of good faith and 
fair dealing, both express and implied, negligent or intentional infliction 
of emotional distress; negligent or intentional misrepresentation; negligent 
or intentional interference with contract or prospective economic advantage; 
negligence; and defamation;

         (d)  any and all claims for violation of any federal, state or 
municipal statute, including, but not limited to, Title VII of the Civil 
Rights Act of 1964, the Civil Rights Act of 1991, the Age Discrimination in  
Employment Act of 1967, the Americans with Disabilities Act of 1990, and the 
California Fair Employment and Housing Act;

         (e)  any and all claims arising out of any other laws and 
regulations relating to employment or employment discrimination; and

         (f)  any and all claims for attorneys' fees and costs.

         The Company and Mr. Inman agree that the release set forth in this 
Section 6 shall be and remain in effect in all respects as a complete general 
release as to the matters released.  This release does not extend to any 
obligations incurred or specified under (i) this Agreement, (ii) the 
Indemnification Agreement dated _____, 199___ between Mr. Inman and the 
Company (the "Indemnification Agreement"), or (iii) attributable to any act 
of fraud by any party hereto.

         Except as expressly provided herein, this Agreement shall supersede 
and render null and void any and all prior agreements between the parties 
other than the Indemnification Agreement, the Options, and the 
Confidentiality Agreement as defined in Section 10 hereof.

    8.   ACKNOWLEDGMENT OF WAIVER OF CLAIMS UNDER ADEA.  Mr. Inman 
acknowledges that he is waiving and releasing any rights he may have under 
the Age Discrimination in Employment Act of 1967 ("ADEA") and that this 
waiver and release is knowing and voluntary.  Mr. Inman and the Company agree 
that this waiver and release does not apply to any rights or claims that may 
arise under ADEA after the Effective Date of this Agreement.  Mr. Inman 
acknowledges that the consideration given for this waiver and release 
Agreement is in addition to anything of value to which Mr. Inman was already 
entitled.  Mr. Inman further acknowledges that he has been advised by this 
writing that (a) he should consult with an attorney PRIOR to executing this 
Agreement; (b) he has at least twenty-one (21) days within which to consider 
this Agreement; (c) he has at least seven (7) days following the execution of 
this Agreement by the Parties to revoke the Agreement (the "Revocation 
Period"); and (d) this Agreement shall not be effective until the Revocation 
Period has expired.

    9.   CIVIL CODE SECTION 1542.  The Parties represent that they are not 
aware of any claim by either of them other than the claims that are released 
by this Agreement.  Mr. Inman and the Company acknowledge that they have been 
advised by legal counsel and are familiar with the provisions of California 
Civil Code Section 1542, which provides as follows:


                                       -4-

<PAGE>

    A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT 
    KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE 
    RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS 
    SETTLEMENT WITH THE DEBTOR.

    Mr. Inman and the Company, being aware of said Code section, agree to 
expressly waive any rights they may have thereunder, as well as under any 
other statute or common law principles of similar effect.

    10.  NONDISCLOSURE OF CONFIDENTIAL AND PROPRIETARY INFORMATION.  Mr. 
Inman understands and agrees that his obligations to the Company under his 
existing Proprietary Information and Inventions Assignment and 
Confidentiality Agreement between Mr. Inman and the Company (the 
"CONFIDENTIALITY AGREEMENT"), a copy of which is attached hereto as EXHIBIT 
A, shall continue through the Termination Date and shall survive termination 
of his relationship with the Company under this Agreement and that Mr. Inman 
shall continue to maintain the confidentiality of all confidential and 
proprietary information of the Company as provided by the Confidentiality 
Agreement.  Mr. Inman agrees that at all times hereafter, he shall not 
intentionally divulge, furnish or make available to any party any of the 
trade secrets, patents, patent applications, price decisions or 
determinations, inventions, customers, proprietary information or other 
intellectual property of the Company, until after such time as such 
information has become publicly known otherwise than by act of collusion of 
Mr. Inman.

    11.  NONCOMPETITION AND NONSOLICITATION.  Mr. Inman agrees that through 
the Service Period, Mr. Inman shall not, without the prior written consent of 
the Company, at any time, directly or indirectly, whether or not for 
compensation, engage in, or have any interest in Pervasive Software Company 
or Sybase Corporation (whether as an employee, officer, director, agent, 
security holder, creditor, consultant, partner or otherwise).  Mr. Inman 
further agrees that through the Service Period and a period of one year 
thereafter, Mr. Inman shall not induce or attempt to induce any person who is 
an employee of the Company, or any affiliated company, to leave the Company, 
or any affiliated company, to become an employee of any person, firm, 
corporation or business that engages in any activity that is in direct 
competition with the Company.  It is expressly agreed by the Parties that 
after the Termination Date Mr. Inman may pursue and engage in full-time 
employment that does not conflict with his obligations under this Section 11 
and that such employment shall not constitute a breach of this Agreement by 
Mr. Inman.

    The Parties intend that the covenant contained in the preceding paragraph 
shall be construed as a series of separate covenants, one for each county or 
other geographic or political subdivision of each jurisdiction in which the 
Company conducts business.  If, in any judicial proceeding, a court shall 
refuse to enforce any of the separate covenants deemed included in this 
paragraph, then the unenforceable covenant shall be deemed eliminated from 
the provisions for the purpose of those proceedings to the extent necessary 
to permit the remaining separate covenants to be enforced.


                                       -5-

<PAGE>

    12.  NON-DISPARAGEMENT.  Each Party agrees to refrain from any 
disparagement, criticism, defamation, slander of the other, or tortious 
interference with the contracts and relationships of the other.  The 
Company's personnel records will reflect that Mr. Inman voluntarily 
terminated his employment on the Employment Termination Date.

    13.  AUTHORITY.  The Company represents and warrants that the undersigned 
has the authority to act on behalf of the Company and to bind the Company and 
all who may claim through it to the terms and conditions of this Agreement. 
Mr. Inman represents and warrants that he has the capacity to act on his own 
behalf and on behalf of all who might claim through him to bind them to the 
terms and conditions of this Agreement.  Each Party warrants and represents 
that there are no liens or claims of lien or assignments in law or equity or 
otherwise of or against any of the claims or causes of action released herein.

    14.  NO REPRESENTATIONS.  Neither Party has relied upon any 
representations or statements made by the other Party hereto which are not 
specifically set forth in this Agreement.

    15.  SEVERABILITY.  In the event that any provision hereof becomes or is 
declared by a court or other tribunal of competent jurisdiction to be 
illegal, unenforceable or void, this Agreement shall continue in full force 
and effect without said provision.

    16.  ARBITRATION.  The Parties shall attempt to settle all disputes 
arising in connection with this Agreement through good faith consultation.  
In the event no agreement can be reached on such dispute within fifteen (15) 
days after notification in writing by either Party to the other concerning 
such dispute, the dispute shall be settled by binding arbitration to be 
conducted in Santa Clara County before the American Arbitration Association 
under its California Employment Dispute Resolution Rules, or by a judge to be 
mutually agreed upon. The arbitration decision shall be final, conclusive and 
binding on both Parties and any arbitration award or decision may be entered 
in any court having jurisdiction.  The Parties agree that the prevailing 
party in any arbitration shall be entitled to injunctive relief in any court 
of competent jurisdiction to enforce the arbitration award.  The Parties 
further agree that the prevailing Party in any such proceeding shall be 
awarded reasonable attorneys' fees and costs.  This Section 16 shall not 
apply to the Confidentiality Agreement.  THE PARTIES HEREBY WAIVE ANY RIGHTS 
THEY MAY HAVE TO TRIAL BY JURY IN REGARD TO ARBITRABLE CLAIMS.

    17.  ENTIRE AGREEMENT.  This Agreement, and the exhibit hereto, represent 
the entire agreement and understanding between the Company and Mr. Inman 
concerning Mr. Inman's separation from the Company, and supersede and replace 
any and all prior agreements and understandings concerning Mr. Inman's 
relationship with the Company and his compensation by the Company, other than 
the Stock Option Agreements described in Section 4 and the Confidentiality 
Agreement described in Section 10.

    18.  NO ORAL MODIFICATION.  This Agreement may only be amended in writing 
signed by Mr. Inman and the Company.

    19.  GOVERNING LAW.  This Agreement shall be governed by the laws of the 
State of California, without regard to its conflicts of law provisions.


                                       -6-

    20.  EFFECTIVE DATE.  This Agreement is effective seven days after it has 
been signed by both Parties and such date is referred to herein as the 
"EFFECTIVE DATE."

    21.  COUNTERPARTS.  This Agreement may be executed in counterparts, and 
each counterpart shall have the same force and effect as an original and 
shall constitute an effective, binding agreement on the part of each of the 
undersigned.

    22.  ASSIGNMENT.  This Agreement may not be assigned by Mr. Inman or the 
Company without the prior written consent of the other party.  
Notwithstanding the foregoing, this Agreement may be assigned by the Company 
to a corporation controlling, controlled by or under common control with the 
Company without the consent of Mr. Inman.

    23.  VOLUNTARY EXECUTION OF AGREEMENT.  This Agreement is executed 
voluntarily and without any duress or undue influence on the part or behalf 
of the Parties hereto, with the full intent of releasing all claims.  The 
Parties acknowledge that: 

         (a)  they have read this Agreement; 

         (b)  they have been represented in the preparation, negotiation, and 
execution of this Agreement by legal counsel of their own choice or that they 
have voluntarily declined to seek such counsel; 

         (c)  they understand the terms and consequences of this Agreement 
and of the releases it contains; and 

         (d)  they are fully aware of the legal and binding effect of this 
Agreement.

                          CENTURA SOFTWARE CORPORATION
                    SETTLEMENT AGREEMENT AND MUTUAL RELEASE
 
    This Settlement Agreement and Mutual Release ("AGREEMENT") is made by and
between Centura Software Corporation, a California corporation (the "COMPANY"),
and Earl M. Stahl ("MR. STAHL").
 
    WHEREAS, Mr. Stahl is employed by the Company; and
 
    WHEREAS, the Company and Mr. Stahl have mutually agreed to terminate the
existing employment relationship and to release each other from any claims
arising from or related to the employment relationship.
 
    NOW, THEREFORE, in consideration of the mutual promises made herein, the
Company and Mr. Stahl (collectively referred to as the "PARTIES") hereby agree
as follows:
 
    1.  RESIGNATION.  Mr. Stahl and the Company agree that Mr. Stahl's status as
Senior Vice President, Engineering and Chief Technical Officer of the Company,
all other positions of the Company held by Mr. Stahl, and Mr. Stahl's full-time
employment with the Company shall terminate on December 8, 1997 (the
"Termination Date"), provided, however, that Mr. Stahl shall remain a Director
of the Company until Mr. Stahl resigns such position or is requested to resign
by the Company's Board of Directors, at which time Mr. Stahl agrees to resign
such position.
 
    2.  CONTINUATION OF EMPLOYMENT.  During the period commencing on December 9,
1997 and continuing thereafter until terminated by the Company or Mr. Stahl in
accordance with this Section 2 (the "Service Period"), Mr. Stahl agrees to
provide services to the Company as follows:
 
        (i) Mr. Stahl shall be available to assist the President, or other
    employees of the Company as designated by the President, in fulfilling such
    projects reasonably consistent with Mr. Stahl's prior position with the
    Company as requested by the President, including without limitation
    providing technical product support on SQL Windows and CTD for bug fixes,
    architecture changes and other matters;
 
        (ii) Mr. Stahl shall report directly to the President of the Company;
    and
 
       (iii) Mr. Stahl shall contact the President no less frequently than
    monthly, at a day and time each month mutually agreed to by Mr. Stahl and
    the President, to report the status of Mr. Stahl's continuing projects for
    the Company.
 
    To facilitate Mr. Stahl's rendering of services to the Company, as set forth
above, during the Service Period, the Company agrees to maintain Mr. Stahl's
electronic mail addresses on the Company's systems, maintain a voice mailbox,
and continue to provide computer equipment as needed. Mr. Stahl hereby
acknowledges and agrees that the performance of his services is on an at-will
basis, that his services may be terminated at any time for any reason by the
Company or Mr. Stahl upon ten (10) days' written notice, and that upon such
termination the Company's compensation obligations to Mr. Stahl under Section 3
below shall terminate.
 
    3.  PAYMENT AND LOAN AGREEMENT.  In consideration for the release of claims
set forth below and for Mr. Stahl's continued services to the Company during the
Service Period, for each month for which Mr. Stahl performs services during the
Service Period, the Company will credit an amount equal to Mr. Stahl's current
monthly base salary (less applicable withholding) first to accrued interest and
then to the outstanding principal balance under the loan pursuant to that
certain Loan Agreement Secured by Property and Securities dated August 31, 1995
by and between the Company and Earl and Ann Stahl (the "Loan" and "Loan
Agreement"). Mr. Stahl acknowledges that he shall not be entitled to any other
payments from the Company for services performed during the Service Period. The
Parties acknowledge and agree that in accordance with Section 3 of the Note
Secured by Deed of Trust under the Loan
 
                                       1
<PAGE>
Agreement, all outstanding principal balance and accrued interest on the Loan
shall become due and payable in full six (6) months after termination of the
Service Period, or if earlier, upon the occurrence of any of the events
specified in items (i), (ii), (iv), (v) and (vi) of such Section 3. The Parties
agree that the Loan and Loan Agreement shall be unmodified and shall remain in
full force and effect.
 
    4.  EMPLOYEE BENEFITS.  Following the Termination Date, Mr. Stahl shall have
the right to continue, at his own expense, coverage under the Company's medical,
dental and vision insurance programs as provided by COBRA. Except as otherwise
provided above, Mr. Stahl shall not be entitled to participate in any of the
Company's benefit plans or programs offered to employees or officers of the
Company.
 
    5.  STOCK OPTIONS.  Options to purchase the Company's Common Stock held by
Mr. Stahl will continue to vest at their regular monthly vesting rate during the
Service Period or so long as Mr. Stahl serves as a member of the Board, and such
options shall thereafter be exercisable with respect to such vested option
shares thereunder for 30 days after the later of the date on which Mr. Stahl
ceases to provide services to the Company in accordance with Section 2 above or
ceases to serve as a Director of the Company.
 
    Mr. Stahl acknowledges and agrees that if the such options are not exercised
within 90 days of the Termination Date, they shall no longer qualify as
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended, and shall thereafter be nonstatutory stock
options. Mr. Stahl further acknowledges and agrees that he shall remain bound by
all terms of the Stock Option Agreements issued by the Company to him.
 
    6.  NO OTHER PAYMENTS DUE.  Mr. Stahl acknowledges and agrees that the
payments being made to him, and the obligations being undertaken by the Company,
as described in this Agreement, constitute all payments which he is entitled to
receive and that, except as expressly provided herein, he is not entitled to any
further or additional compensation or benefit from the Company. Mr. Stahl
acknowledges that, in light of the payment by the Company of all wages due, or
to become due to Mr. Stahl, California Labor Code Section 206.5 is not
applicable to the Parties hereto. That section provides in pertinent part as
follows:
 
    No employer shall require the execution of any release of any claim or right
    on account of wages due, or to become due, or made as an advance on wages to
    be earned, unless payment of such wages has been made.
 
    7.  RELEASE OF CLAIMS.  In consideration for the obligations of both parties
set forth in this Agreement, Mr. Stahl and the Company, on behalf of themselves,
and their respective heirs, executors, officers, directors, employees,
investors, stockholders, administrators and assigns, hereby fully and forever
release each other and their respective heirs, executors, officers, directors,
employees, investors, stockholders, administrators and assigns, of and from any
claim, duty, obligation or cause of action relating to any matters of any kind,
whether presently known or unknown, suspected or unsuspected, that any of them
may possess arising from any omissions, acts or facts that have occurred up
until and including the date of this Agreement including, without limitation:
 
        (a) any and all claims relating to or arising from Mr. Stahl's
    employment relationship with the Company and the termination of that
    relationship;
 
        (b) any and all claims relating to, or arising from, Mr. Stahl's right
    to purchase, or actual purchase of shares of stock of the Company;
 
        (c) any and all claims for wrongful discharge of employment; breach of
    contract, both express and implied; breach of a covenant of good faith and
    fair dealing, both express and implied, negligent or intentional infliction
    of emotional distress; negligent or intentional misrepresentation; negligent
    or intentional interference with contract or prospective economic advantage;
    negligence; and defamation;
 
                                       2
<PAGE>
        (d) any and all claims for violation of any federal, state or municipal
    statute, including, but not limited to, Title VII of the Civil Rights Act of
    1964, the Civil Rights Act of 1991, the Age Discrimination in Employment Act
    of 1967, the Americans with Disabilities Act of 1990, and the California
    Fair Employment and Housing Act;
 
        (e) any and all claims arising out of any other laws and regulations
    relating to employment or employment discrimination; and
 
        (f) any and all claims for attorneys' fees and costs.
 
    The Company and Mr. Stahl agree that the release set forth in this Section 6
shall be and remain in effect in all respects as a complete general release as
to the matters released. This release does not extend to any obligations
incurred or specified under (i) this Agreement, (ii) the Indemnification
Agreement dated            , 199 between Mr. Stahl and the Company (the
"Indemnification Agreement"), or (iii) attributable to any act of fraud by any
party hereto.
 
    Except as expressly provided herein, this Agreement shall supersede and
render null and void any and all prior agreements between the parties other than
the Indemnification Agreement, Mr. Stahl's options, and the Confidentiality
Agreement as defined in Section 10 hereof.
 
    8.  ACKNOWLEDGMENT OF WAIVER OF CLAIMS UNDER ADEA.  Mr. Stahl acknowledges
that he is waiving and releasing any rights he may have under the Age
Discrimination in Employment Act of 1967 ("ADEA") and that this waiver and
release is knowing and voluntary. Mr. Stahl and the Company agree that this
waiver and release does not apply to any rights or claims that may arise under
ADEA after the Effective Date of this Agreement. Mr. Stahl acknowledges that the
consideration given for this waiver and release Agreement is in addition to
anything of value to which Mr. Stahl was already entitled. Mr. Stahl further
acknowledges that he has been advised by this writing that (a) he should consult
with an attorney PRIOR to executing this Agreement; (b) he has at least
twenty-one (21) days within which to consider this Agreement; (c) he has at
least seven (7) days following the execution of this Agreement by the Parties to
revoke the Agreement (the "Revocation Period"); and (d) this Agreement shall not
be effective until the Revocation Period has expired.
 
    9.  CIVIL CODE SECTION 1542.  The Parties represent that they are not aware
of any claim by either of them other than the claims that are released by this
Agreement. Mr. Stahl and the Company acknowledge that they have been advised by
legal counsel and are familiar with the provisions of California Civil Code
Section 1542, which provides as follows:
 
    A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW
    OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH
    IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE
    DEBTOR.
 
    Mr. Stahl and the Company, being aware of said Code section, agree to
expressly waive any rights they may have thereunder, as well as under any other
statute or common law principles of similar effect.
 
    10. NONDISCLOSURE OF CONFIDENTIAL AND PROPRIETARY INFORMATION.  Mr. Stahl
understands and agrees that his obligations to the Company under his existing
Proprietary Information and Inventions Assignment and Confidentiality Agreement
between Mr. Stahl and the Company (the "CONFIDENTIALITY AGREEMENT"), a copy of
which is attached hereto as EXHIBIT A, shall continue through the Termination
Date and shall survive termination of his relationship with the Company under
this Agreement and that Mr. Stahl shall continue to maintain the confidentiality
of all confidential and proprietary information of the Company as provided by
the Confidentiality Agreement. Mr. Stahl agrees that at all times hereafter, he
shall not intentionally divulge, furnish or make available to any party any of
the trade secrets, patents, patent applications, price decisions or
determinations, inventions, customers, proprietary information or other
 
                                       3
<PAGE>
intellectual property of the Company, until after such time as such information
has become publicly known otherwise than by act of collusion of Mr. Stahl.
 
    11. NONCOMPETITION AND NONSOLICITATION.  Mr. Stahl agrees that through the
Service Period, Mr. Stahl shall not, without the prior written consent of the
Company, at any time, directly or indirectly, whether or not for compensation,
engage in, or have any interest in Pervasive Software Company or Sybase
Corporation (whether as an employee, officer, director, agent, security holder,
creditor, consultant, partner or otherwise). Mr. Stahl further agrees that
through the Service Period and a period of one year thereafter, Mr. Stahl shall
not induce or attempt to induce any person who is an employee of the Company, or
any affiliated company, to leave the Company, or any affiliated company, to
become an employee of any person, firm, corporation or business described above.
It is expressly agreed by the Parties that after the Termination Date Mr. Stahl
may pursue and engage in full-time employment that does not conflict with his
obligations under this Section 11 and that such employment shall not constitute
a breach of this Agreement by Mr. Stahl.
 
    The Parties intend that the covenant contained in the preceding paragraph
shall be construed as a series of separate covenants, one for each county or
other geographic or political subdivision of each jurisdiction in which the
Company conducts business. If, in any judicial proceeding, a court shall refuse
to enforce any of the separate covenants deemed included in this paragraph, then
the unenforceable covenant shall be deemed eliminated from the provisions for
the purpose of those proceedings to the extent necessary to permit the remaining
separate covenants to be enforced.
 
    12. NON-DISPARAGEMENT.  Each Party agrees to refrain from any disparagement,
criticism, defamation, slander of the other, or tortious interference with the
contracts and relationships of the other. The Company's personnel records will
reflect that Mr. Stahl voluntarily terminated his employment on the Employment
Termination Date.
 
    13. AUTHORITY.  The Company represents and warrants that the undersigned has
the authority to act on behalf of the Company and to bind the Company and all
who may claim through it to the terms and conditions of this Agreement. Mr.
Stahl represents and warrants that he has the capacity to act on his own behalf
and on behalf of all who might claim through him, including his spouse, Ann
Stahl, to bind them to the terms and conditions of this Agreement. Each Party
warrants and represents that there are no liens or claims of lien or assignments
in law or equity or otherwise of or against any of the claims or causes of
action released herein.
 
    14. NO REPRESENTATIONS.  Neither Party has relied upon any representations
or statements made by the other Party hereto which are not specifically set
forth in this Agreement.
 
    15. SEVERABILITY.  In the event that any provision hereof becomes or is
declared by a court or other tribunal of competent jurisdiction to be illegal,
unenforceable or void, this Agreement shall continue in full force and effect
without said provision.
 
    16. ARBITRATION.  The Parties shall attempt to settle all disputes arising
in connection with this Agreement through good faith consultation. In the event
no agreement can be reached on such dispute within fifteen (15) days after
notification in writing by either Party to the other concerning such dispute,
the dispute shall be settled by binding arbitration to be conducted in Santa
Clara County before the American Arbitration Association under its California
Employment Dispute Resolution Rules, or by a judge to be mutually agreed upon.
The arbitration decision shall be final, conclusive and binding on both Parties
and any arbitration award or decision may be entered in any court having
jurisdiction. The Parties agree that the prevailing party in any arbitration
shall be entitled to injunctive relief in any court of competent jurisdiction to
enforce the arbitration award. The Parties further agree that the prevailing
Party in any such proceeding shall be awarded reasonable attorneys' fees and
costs. This Section 16 shall not apply to the Confidentiality Agreement. THE
PARTIES HEREBY WAIVE ANY RIGHTS THEY MAY HAVE TO TRIAL BY JURY IN REGARD TO
ARBITRABLE CLAIMS.
 
                                       4

    17. ENTIRE AGREEMENT.  This Agreement, and the exhibit hereto, represent the
entire agreement and understanding between the Company and Mr. Stahl concerning
Mr. Stahl's separation from the Company, and supersede and replace any and all
prior agreements and understandings concerning Mr. Stahl's relationship with the
Company and his compensation by the Company, other than the Loan and Loan
Agreement described in Section 2, the Confidentiality Agreement described in
Section 10, and the Option Agreements between the Company and Mr. Stahl, which
agreements shall remain in full force and effect.
 
    18. NO ORAL MODIFICATION.  This Agreement may only be amended in writing
signed by Mr. Stahl and the Company.
 
    19. GOVERNING LAW.  This Agreement shall be governed by the laws of the
State of California, without regard to its conflicts of law provisions.
 
    20. EFFECTIVE DATE.  This Agreement is effective seven days after it has
been signed by both Parties and such date is referred to herein as the
"EFFECTIVE DATE."
 
    21. COUNTERPARTS.  This Agreement may be executed in counterparts, and each
counterpart shall have the same force and effect as an original and shall
constitute an effective, binding agreement on the part of each of the
undersigned.
 
    22. ASSIGNMENT.  This Agreement may not be assigned by Mr. Stahl or the
Company without the prior written consent of the other party. Notwithstanding
the foregoing, this Agreement may be assigned by the Company to a corporation
controlling, controlled by or under common control with the Company without the
consent of Mr. Stahl.
 
    23. VOLUNTARY EXECUTION OF AGREEMENT.  This Agreement is executed
voluntarily and without any duress or undue influence on the part or behalf of
the Parties hereto, with the full intent of releasing all claims. The Parties
acknowledge that:
 
        (a) they have read this Agreement;
 
        (b) they have been represented in the preparation, negotiation, and
    execution of this Agreement by legal counsel of their own choice or that

Coast will have the right to require, as a condition to its consent under 
subparagraph (d) above, that the holder of the additional security interest 
or lien sign an intercreditor agreement on Coast's then standard form, 
acknowledge that the security interest is subordinate to the security 
interest in favor of Coast, and agree not to take any action to enforce its 
subordinate security interest so long as any Obligations remain outstanding, 
and that Borrower agree that any uncured default in any obligation in excess 
of $100,000 secured by the subordinate security interest shall also 
constitute an Event of Default under this Agreement.

     "PERSON" means any individual, sole proprietorship, general partnership, 
limited partnership, limited liability partnership, limited liability 
company, joint venture, trust, unincorporated organization, association, 
corporation, government, or any agency or political division thereof, or any 
other entity.

     "PRIME RATE" means the actual "Reference Rate" or the substitute 
therefor of the Bank of America NT & SA whether or not that rate is the 
lowest interest rate charged by said bank.  If the Prime Rate, as defined, is 
unavailable, "Prime Rate" shall mean the highest of the prime rates published 
in the Wall Street Journal on the first business day of the applicable month, 
as the base rate on corporate loans at large U.S. money center commercial 
banks.

     "RECEIVABLE LOANS" means the Loans described in Section 2(a) of the

and all other rights or remedies of an unpaid vendor, lienor or secured party.

     "RENEWAL DATE" shall mean the Maturity Date if this Agreement is renewed

on such date (a) at fair valuations, all of the properties and assets of such 
Person are greater than the sum of the debts, including contingent 
liabilities, of such Person, (b) the present fair salable value of the 
properties and assets of such Person is not less than the amount that will be 
required to pay the probable liability of such Person on its debts as they 
become absolute and matured, (c) such Person is able to realize upon its 
properties and assets and pay its debts and other liabilities, contingent 
obligations and other commitments as they mature in the normal course of 
business, (d) such Person does not intend to, and does not believe that it 
will, incur debts beyond such Person's ability to pay as such debts mature, 
and (e) such Person is not engaged in business or a transaction, and is not 
about to engage in business or a transaction, for which such Person's 
properties and assets would constitute unreasonably small capital after 
giving due consideration to the prevailing practices in the industry in which 
such Person is engaged.  In computing the amount of contingent liabilities at 
any time, it is intended that such liabilities will be computed at the amount 
that, in light of all the facts and circumstances existing at such time, 
represents the amount that reasonably can be expected to become an actual or 
matured liability.

Borrower represents and warrants to Coast as follows, and Borrower covenants 
that the following representations will continue to be true, and that 
Borrower will at all times comply with all of the following covenants:

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

     6.2  NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in the 
heading to this Agreement is its correct name.  Listed on the Schedule are 
all prior names of Borrower and all of Borrower's present and prior trade 
names. Borrower shall give Coast thirty (30) days' prior written notice 

                                      7

<PAGE>
COAST BUSINESS CREDIT                              LOAN AND SECURITY AGREEMENT
- ------------------------------------------------------------------------------

before changing its name or doing business under any other name.  Borrower 
has complied, and will in the future comply, with all laws relating to the 
conduct of business under a fictitious business name.

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

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

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

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

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

     6.8    TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS.  Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state and local law, and Borrower has timely paid, and will
timely pay, all foreign, federal, state and local taxes, assessments, deposits
and contributions now or in the future owed by Borrower.  Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Coast in writing
of the commencement of, and any material development in, the proceedings, and
(iii) posts bonds or takes any other steps required to keep the contested taxes
from becoming a lien upon any of the Collateral.  As of the date hereof,
Borrower is unaware of any claims or adjustments proposed for any of Borrower's
prior tax years which could result in additional taxes becoming due and payable
by Borrower.  Borrower has paid, and shall continue to pay all amounts necessary
to fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which

                                      8
<PAGE>
COAST BUSINESS CREDIT                              LOAN AND SECURITY AGREEMENT
- ------------------------------------------------------------------------------

could result in any liability of Borrower, including any liability to the 
Pension Benefit Guaranty Corporation or its successors or any other 
governmental agency. Borrower shall, at all times, utilize the services of an 
outside payroll service providing for the automatic deposit of all payroll 
taxes payable by Borrower.

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

     6.10  LITIGATION.  Except as disclosed in the Schedule, there is no 
claim, suit, litigation, proceeding or investigation pending or (to best of 
Borrower's knowledge) threatened by or against or affecting Borrower in any 
court or before any governmental agency (or any basis therefor known to 
Borrower) which may result, either separately or in the aggregate, in a 
Material Adverse Effect.  Borrower will promptly inform Coast in writing of 
any claim, proceeding, litigation or investigation in the future threatened 
or instituted by or against Borrower involving an amount set forth on the 
Schedule.

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

    6.12  COMPUTER ASSOCIATES.  The Obligations of Borrower to Coast shall at 
all times constitute permitted Indebtedness as permitted in Section 7(e) of 
that certain Floating Rate Convertible Subordinated Note Due 1998 ("Floating 
Rate Convertible Note") in the face amount of $10,000,000 made by Borrower in 
favor of Computer Associates International, Inc. dated April 3, 1995.  

7.   RECEIVABLES.

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

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

     7.3  SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES.  Borrower shall 
deliver to Coast via facsimile, unless otherwise directed by Coast, at such 
locations and at such intervals as Coast may request, transaction reports and 
loan requests, schedules of Receivables, and schedules of collections, all on 
Coast's standard forms; provided, however, that Borrower's failure to execute 
and deliver the same shall not affect or limit Coast's security interest and 
other rights in all of Borrower's Receivables, nor shall Coast's failure to 
advance or lend against a specific Receivable affect or limit Coast's 
security interest and other rights therein.  Loan requests received after 
10:30 A.M. Los Angeles, California time, will not be considered by Coast 
until the next Business Day.  Together with each such schedule, or later if 
requested by Coast, Borrower shall furnish Coast with copies (or, at Coast's 
request, originals) of all contracts, orders, invoices, and other similar 
documents, and all original shipping instructions, delivery receipts, bills 
of lading, and other evidence of delivery, for any


                                      9
<PAGE>
COAST BUSINESS CREDIT                              LOAN AND SECURITY AGREEMENT
- ------------------------------------------------------------------------------

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

     7.4  COLLECTION OF RECEIVABLES.  Borrower shall have the right to 
collect all Receivables, unless and until an Event of Default has occurred. 
Borrower shall hold all payments on, and proceeds of, Receivables in trust 
for Coast, and Borrower shall deliver all such payments and proceeds to Coast 
within one (1) Business Day after receipt by Borrower, in their original 
form, duly endorsed to Coast, to be applied to the Obligations in such order 
as Coast shall determine.  Coast may, in its discretion, require that all 
proceeds of Collateral be deposited by Borrower into a lockbox account, or 
such other "blocked account" as Coast may specify, pursuant to a blocked 
account agreement in such form as Coast may specify.  Coast or its designee 
may, at any time, notify Account Debtors that Coast has been granted a 
security interest in the Receivables.

     7.5  REMITTANCE OF PROCEEDS.  All proceeds arising from the disposition 
of any Collateral shall be delivered to Coast within one (1) Business Day 
after receipt by Borrower, in their original form, duly endorsed to Coast, to 
be applied to the Obligations in such order as Coast shall determine.  
Borrower agrees that it will not commingle proceeds of Collateral with any of 
Borrower's other funds or property, but will hold such proceeds separate and 
apart from such other funds and property and in an express trust for Coast.  
Nothing in this Section limits the restrictions on disposition of Collateral 
set forth elsewhere in this Agreement.

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

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

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

     7.9  NO LIABILITY.  Coast shall not under any circumstances be 
responsible or liable for any shortage or discrepancy in, damage to, or loss 
or destruction of, any goods, the sale or other disposition of which gives 
rise to a Receivable, or for any error, act, omission or delay of any kind 
occurring in the settlement, failure to settle, collection or failure to 
collect any Receivable, or for settling any Receivable in good faith for less 
than the


                                      10
<PAGE>
COAST BUSINESS CREDIT                              LOAN AND SECURITY AGREEMENT
- ------------------------------------------------------------------------------

full amount thereof, nor shall Coast be deemed to be responsible for any of 
Borrower's obligations under any contract or agreement giving rise to a 
Receivable.  Nothing herein shall, however, relieve Coast from liability for 
its own gross negligence or willful misconduct.

8.  ADDITIONAL DUTIES OF THE BORROWER.

     8.1  FINANCIAL AND OTHER COVENANTS.  Borrower shall at all times comply 
with the financial and other covenants set forth in the Schedule.

     8.2  INSURANCE.  Borrower shall, at all times insure all of the tangible 
personal property Collateral and carry such other business insurance, with 
insurers reasonably acceptable to Coast, in such form and amounts as Coast 
may reasonably require, and Borrower shall provide evidence of such insurance 
to Coast, so that Coast is satisfied that such insurance is, at all times, in 
full force and effect.  All liability insurance policies of Borrower shall 
name Coast as an additional insured, and all property casualty and related 
insurance policies of Borrower shall name Coast as a loss payee thereon and 
Borrower shall cause a lender's loss payee endorsement in form reasonably 
acceptable to Coast. Upon receipt of the proceeds of any such insurance, 
Coast shall apply such proceeds in reduction of the Obligations as Coast 
shall determine in its sole discretion, except that, provided no Default or 
Event of Default has occurred and is continuing, Coast shall release to 
Borrower insurance proceeds with respect to Equipment totaling less than the 
amount set forth in Section 8 of the Schedule, which shall be utilized by 
Borrower for the replacement of the Equipment with respect to which the 
insurance proceeds were paid.  Coast may require reasonable assurance that 
the insurance proceeds so released will be so used.  If Borrower fails to 
provide or pay for any insurance, Coast may, but is not obligated to, obtain 
the same at Borrower's expense.  Borrower shall promptly deliver to Coast 
copies of all reports made to insurance companies.

     8.3  REPORTS.  Borrower, at its expense, shall provide Coast with the 
written reports set forth in Section 8 of the Schedule, and such other 
written reports with respect to Borrower (including budgets, sales 
projections, operating plans and other financial documentation), as Coast 
shall from time to time reasonably specify.

     8.4  ACCESS TO COLLATERAL, BOOKS AND RECORDS.  At reasonable times but 
not less frequently than quarterly and on three (3) Business Day's notice (1 
Business Day if an Event of Default has occurred and is continuing), Coast, 
or its agents, shall have the right to perform Audits.  Coast shall take 
reasonable steps to keep confidential all confidential information obtained 
in any Audit, but Coast shall have the right to disclose any such information 
to its auditors, regulatory agencies, and attorneys, and pursuant to any 
subpoena or other legal process.  The Audits shall be at Borrower's expense 
and the charge for the Audits shall be Seven Hundred Fifty Dollars ($750) per 
person per day (or such higher amount as shall represent Coast's then current 
standard charge for the same), plus reasonable out-of-pocket expenses.  
Borrower will not enter into any agreement with any accounting firm, service 
bureau or third party to store Borrower's books or records at any location 
other than Borrower's Address, without first notifying Coast of the same and 
obtaining the written agreement from such accounting firm, service bureau or 
other third party to give Coast the same rights with respect to access to 
books and records and related rights as Coast has under this Loan Agreement.

written consent, do any of the following:

     (a)  merge or consolidate with another entity, except in a transaction

     (b)  acquire any assets, except (i) in the ordinary course of business,

interests in Borrower (except for dividends or distributions payable solely

notwithstanding anything to the contrary herein and so long as no Event of 
Default has occurred and is continuing, Borrower may repurchase the stock of 
any terminated officer, director or employee in an amount not to exceed the 
then amount of Borrower's cash in banks located in the United States less the 
Obligations (other than the Loans against the Eligible Foreign Receivables) 
then owing to Coast;

     (k)  make any change in Borrower's capital structure which would have a

     (l)  dissolve or elect to dissolve.

only permitted if no Default or Event of Default is continuing or would occur 
as a result of such transaction.

     8.6  LITIGATION COOPERATION.  Should any third-party suit or proceeding 
be instituted by or against Coast with respect to any Collateral or relating 
to Borrower, Borrower shall, without expense to Coast, make available 
Borrower and its officers, employees and agents and Borrower's books and 
records, to the extent that Coast may deem them reasonably necessary in order 
to prosecute or defend any such suit or proceeding.

     8.7  FURTHER ASSURANCES.  Borrower agrees, at its expense, on request by 
Coast, to execute all documents and take all actions, as Coast, may deem 
reasonably necessary or useful in order to perfect and maintain Coast's 
perfected security interest in the Collateral, and in order to fully 
consummate the transactions contemplated by this Agreement.

9.  TERM.

     9.1  MATURITY DATE.  This Agreement shall continue in effect until the 
Maturity Date; provided that the Maturity Date shall automatically be 
extended, and this Agreement shall automatically and continuously renew, for 
successive additional terms of one year each, unless one party gives written 
notice to the other, not less than 120 days prior to the Maturity Date or the 
next Renewal Date, that such party elects to terminate this Agreement 
effective on the Maturity Date or such next Renewal Date.  If this Agreement 
is renewed under this Section 9.1, Borrower shall pay to Coast a Renewal Fee 
in the amount shown in Section 3 of the Schedule.  The Renewal Fee shall be 
due and payable on the Renewal Date and thereafter shall bear interest at a 
rate equal to the rate applicable to the Receivable Loans.

     9.2  EARLY TERMINATION.  This Agreement may be terminated prior to the 
Maturity Date as follows:  (a) by Borrower, effective three (3) Business Days 
after written notice of termination is given to Coast; or (b) by Coast at any 
time after the occurrence of an Event of Default, without notice, effective 
immediately.  If this Agreement is terminated by Borrower or by Coast under 
this Section 9.2, Borrower shall pay to Coast an Early Termination Fee in the 
amount shown in Section 3 of the Schedule.  The Early Termination Fee shall 
be due and payable on the effective date of termination and thereafter shall 
bear interest at a rate equal to the rate applicable to the Receivable Loans.

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

all Obligations, whether evidenced by installment notes or otherwise, and 
whether or not all or any part of such Obligations are otherwise then due and 
payable. Notwithstanding any termination of this Agreement, all of Coast's 
security interests in all of the Collateral and all of the terms and 
provisions of this Agreement shall continue in full force and effect until 
all Obligations have been paid and performed in full; provided that, without 
limiting the fact that Loans are subject to the discretion of Coast, Coast 
may, in its sole discretion, refuse to make any further Loans after 
termination.  No termination shall in any way affect or impair any right or 
remedy of Coast, nor shall any such termination relieve Borrower of any 
Obligation to Coast, until all of the Obligations have been paid and 
performed in full.  Upon payment and performance in full of all the 
Obligations and termination of this Agreement, Coast shall promptly deliver 
to Borrower termination statements, requests for reconveyances and such other 
documents as may be required to fully terminate Coast's security interests.

10.  EVENTS OF DEFAULT AND REMEDIES.

     10.1   EVENTS OF DEFAULT.  The  occurrence of any of the following 
events shall constitute an "Event of Default" under this Agreement, and 
Borrower shall give Coast immediate written notice thereof:

     (a)  Any warranty, representation, statement, report or certificate made 
or delivered to Coast by Borrower or any of Borrower's officers, employees or 
agents, now or in the future, shall be untrue or misleading and results in a 
Material Adverse Effect; or

     (b)  Borrower shall fail to pay when due any Loan or any interest 
thereon or any other monetary Obligation; or

books and records or Collateral as provided in Section 8.4 above, or shall 
breach any negative covenant set forth in Section 8.5 above; or

     (e)  Borrower shall fail to comply with the financial covenants (if any) 
set forth in the Schedule or shall fail to perform any other non-monetary

which failure is not cured within five (5) Business Days after the date due; 
or

(other than a Permitted Lien) is made on all or any part of the Collateral 
which is not cured within ten (10) days after the occurrence of the same; or

     (h)  any default or event of default occurs under any obligation in 
excess of $100,000 secured by a Permitted Lien, which is not cured within any 
applicable cure period or waived in writing by the holder of the Permitted 
Lien or if that certain Floating Rate Convertible Note is not converted to 
equity within 30 days from the date hereof or if there is a declared default 
or breach of the Floating Rate Convertible Note; or

of any proceeding by Borrower or any guarantor of any of the Obligations 
under any reorganization, bankruptcy, insolvency, arrangement, readjustment 
of debt, dissolution or liquidation law or statute of any jurisdiction, now 
or in the future in effect; or

     (k)  the commencement of any proceeding against Borrower or any 
guarantor of any of the Obligations under any reorganization, bankruptcy, 
insolvency, arrangement, readjustment of debt, dissolution or liquidation law 
or statute of any jurisdiction, now or in the future in effect, which is (i) 
not timely controverted, or (ii) not cured by the dismissal thereof within 
thirty (30) days after the date commenced; or

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

          (l)  revocation or termination of, or limitation or denial of 
liability upon, any guaranty of the Obligations or any attempt to do any of 
the foregoing, or commencement of proceedings by any guarantor of any of the 
Obligations under any bankruptcy or insolvency law; or

          (m)  revocation or termination of, or limitation or denial of 
liability upon, any pledge of any certificate of deposit, securities or other 
property or asset of any kind pledged by any third party to secure any or all 
of the Obligations, or any attempt to do any of the foregoing, or 
commencement of proceedings by or against any such third party under any 
bankruptcy or insolvency law; or

          (n)  Borrower or any guarantor of any of the Obligations makes any 
payment on account of any indebtedness or obligation which has been 
subordinated to the Obligations, other than as permitted in the applicable 
subordination agreement, or if any Person who has subordinated such 
indebtedness or obligations terminates or in any way limits his subordination 
agreement; or

          (o)  Except as permitted under Section 8.5(a), Borrower shall 
suffer or experience any Change of Control without Coast's prior written 
consent, which consent shall be in the discretion of Coast in the exercise of 
its reasonable business judgment; or

          (p)  Borrower shall generally not pay its debts as they become due, 
or Borrower shall conceal, remove or transfer any part of its property, with 
intent to hinder, delay or defraud its creditors, or make or suffer any 
transfer of any of its property which may be fraudulent under any bankruptcy, 
fraudulent conveyance or similar law; or

          (q)  there shall be any Material Adverse Effect.

Coast may cease making any Loans or extending any credit hereunder during any 
of the above cure periods.

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

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

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

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

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

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

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

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

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

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

Coast is hereby granted a license or other right to use, without charge, 
Borrower's labels, patents, copyrights, rights of use of any name, trade 
secrets, trade names, trademarks, service marks, and advertising matter, or 
any property of a similar nature, as it pertains to the Collateral, in 
completing production of, advertising for sale, and selling any Collateral 
and Borrower's rights under all licenses and all franchise agreements shall 
inure to Coast's benefit;

          (f)  Sell, lease or otherwise dispose of any of the Collateral, in 
its condition at the time Coast obtains possession of it or after further 
manufacturing, processing or repair, at one or more public and/or private 
sales, in lots or in bulk, for cash, exchange or other property, or on 
credit, and to adjourn any such sale from time to time without notice other 
than oral announcement at the time scheduled for sale.  Coast shall have the 
right to conduct such disposition on Borrower's premises without charge, for 
such time or times as Coast deems reasonable, or on Coast's premises, or 
elsewhere and the Collateral need not be located at the place of disposition. 
Coast may directly or through any affiliated company purchase or lease any 
Collateral at any such public disposition, and if permissible under 
applicable law, at any private disposition.  Any sale or other disposition of 
Collateral shall not relieve Borrower of any liability Borrower may have if 
any Collateral is defective as to title or physical condition or otherwise at 
the time of sale;

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

          (h)  Demand and receive possession of any of Borrower's federal and 
state income tax returns and the books and records utilized in the 
preparation thereof or referring thereto.

     All attorneys' fees, expenses, costs, liabilities and obligations 
incurred by Coast (including attorneys' fees and expenses incurred in 
connection with bankruptcy) with respect to the foregoing shall be due from 
the Borrower to Coast on demand. Coast may charge the same to Borrower's loan 
account, and the same shall thereafter bear interest at the same rate as is 
applicable to the Receivable Loans.  Without limiting any of Coast's rights 
and remedies, from and after the occurrence of any Event of Default, the 
interest rate applicable to the Obligations shall be increased by an 
additional three percent per annum.

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

          (a)  Notice of the sale is given to Borrower at least five (5) days 
prior to the sale, and, in the case of a public sale, notice of the sale is 
published at least five (5) days before the sale in a newspaper of general 
circulation in the county where the sale is to be conducted;

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

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

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

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

          (f)  With respect to any sale of any of the Collateral, Coast may 
(but is not obligated to) direct any prospective purchaser to ascertain 
directly from Borrower any and all information concerning the same.

     Coast shall be free to employ other methods of noticing and selling the 
Collateral, in its discretion, if they are commercially reasonable.

     10.4 POWER OF ATTORNEY. Borrower grants to Coast an irrevocable power of 
attorney

                                       15
<PAGE>

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

coupled with an interest, authorizing and permitting Coast (acting through 
any of its employees, attorneys or agents) at any time, at its option, but 
without obligation, with or without notice to Borrower, and at Borrower's 
expense, to do any or all of the following, in Borrower's name or otherwise, 
but Coast agrees to exercise the following powers in a commercially 
reasonable manner:

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

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

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

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

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

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

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

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

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

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

          (k)  Take any action or pay any sum required of Borrower pursuant 
to this Agreement and any other present or future agreements.

     Any and all sums paid and any and all costs, expenses, liabilities, 
obligations and attorneys' fees incurred by Coast (including attorneys' fees 
and expenses incurred pursuant to bankruptcy) with respect to the foregoing 
shall be added to and become part of the Obligations, and shall be payable on 
demand. Coast may charge the foregoing to Borrower's loan account and the 
foregoing shall thereafter bear interest at the same rate applicable to the 
Receivable Loans. In no event shall Coast's rights under the foregoing power 
of attorney or any of Coast's other rights under this Agreement be deemed to 
indicate that Coast is in control of the business, management or properties 
of Borrower. Borrower shall pay, indemnify, defend, and hold Coast and each 
of its officers, directors, employees, counsel, agents, and attorneys-in-fact 
(each, an "Indemnified Person") harmless (to the fullest extent permitted by 
law) from and against any and all claims, demands, suits, actions, 
investigations, proceedings, and damages, and all attorneys fees and 
disbursements and other costs and expenses actually incurred in connection 
therewith (as and when they are incurred and irrespective of whether suit is 
brought), at any time asserted against, imposed upon, or incurred by any of 
them in connection with or as a result of or related to the execution, 
delivery, enforcement, performance, and administration of this Agreement and 
any other Loan Documents or the transactions contemplated herein, and with 
respect to any investigation, litigation, or proceeding related to

                                       16
<PAGE>

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

this Agreement, any other Loan Document, or the use of the proceeds of the 
credit provided hereunder (irrespective of whether any Indemnified Person is 
a party thereto), or any act, omission, event or circumstance in any manner 
related thereto (all the foregoing, collectively, the "Indemnified 
Liabilities").  Borrower shall have no obligation to any Indemnified Person 
hereunder with respect to any Indemnified Liability that a court of competent 
jurisdiction finally determines to have resulted from the gross negligence or 
willful misconduct of such Indemnified Person.  This provision shall survive 
the termination of this Agreement and the repayment of the Obligations.

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

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

11.  GENERAL PROVISIONS.

     11.1  INTEREST COMPUTATION. In computing interest on the Obligations, all 
checks, wire transfers and other items of payment received by Coast 
(including proceeds of Receivables and payment of the Obligations in full) 
shall be deemed applied by Coast on account of the Obligations three (3) 
Business Days after receipt by Coast of immediately available funds, and, for 
purposes of the foregoing, any such funds received after 10:30 AM Los 
Angeles, California time, on any day shall be deemed received on the next 
Business Day.  Coast shall be entitled to charge Borrower's account for such 
three (3) Business Days of "clearance" or "float" at the rate(s) set forth in 
Section 3 of the Schedule on all checks, wire transfers and other items 
received by Coast, regardless of whether such three (3) Business Days of 
"clearance" or "float" actually occur, and shall be deemed to be the 
equivalent of charging three (3) Business Days of interest on such 
collections.  This across-the-board three (3) Business Day clearance or float 
charge on all collections is acknowledged by the parties to constitute an 
integral aspect of the pricing of Coast's financing of Borrower. 
Notwithstanding the foregoing, if a lock box or blocked account is 
established in form and substance acceptable in the discretion of Coast, the 
float or clearance days in this Section 11.1 shall be reduced to one (1) 
Business Day. Coast shall not, however, be required to credit Borrower's 
account for the amount of any item of payment which is unsatisfactory to 
Coast in its sole discretion, and Coast may charge Borrower's loan account 
for the amount of any item of payment which is returned to Coast unpaid.

     11.2  APPLICATION OF PAYMENTS. Subject to Section 7.5 hereof, all 
payments with respect to the Obligations may be applied, and in Coast's sole 
discretion reversed and re-applied, to the Obligations, in such order and 
manner as Coast shall determine in its sole discretion.

     11.3  CHARGES TO ACCOUNTS. Coast may, in its discretion, require that 
Borrower pay monetary Obligations in cash to Coast, or charge them to 
Borrower's Loan account, in which event they will bear interest from the date 
due to the date paid at the same rate applicable to the Loans.

     11.4  MONTHLY ACCOUNTINGS. Coast shall provide Borrower monthly with an 
account of advances, charges, expenses and payments made

                                       17
<PAGE>

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

pursuant to this Agreement.  Such account shall be deemed correct, accurate 
and binding on Borrower and an account stated (except for reverses and 
reapplications of payments made and corrections of errors discovered by 
Coast), unless Borrower notifies Coast in writing to the contrary within 
thirty (30) days after each account is rendered, describing the nature of any 
alleged errors or omissions.

     11.5  NOTICES. All notices to be given under this Agreement shall be in 
writing and shall be given either personally or by reputable private delivery 
service or by regular first-class mail, facsimile or certified mail return 
receipt requested, addressed to Coast or Borrower at the addresses shown in 
the heading to this Agreement, or at any other address designated in writing 
by one party to the other party.  Notices to Coast shall be directed to the 
Commercial Finance Division, to the attention of the Division Manager or the 
Division Credit Manager.  All notices shall be deemed to have been given upon 
delivery in the case of notices personally delivered, faxed (at time of 
confirmation of transmission), or at the expiration of one (1) Business Day 
following delivery to the private delivery service, or two (2) Business Days 
following the deposit thereof in the United States mail, with postage prepaid.

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

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

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

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

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

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

     11.12 ATTORNEYS FEES, COSTS AND CHARGES. Borrower shall reimburse Coast 
for all attorneys' fees (including attorneys' fees and expenses incurred 
pursuant to bankruptcy) and all filing, recording, search, title insurance, 
appraisal, audit, and other costs incurred by Coast, pursuant to, or in 
connection with, or relating to this Agreement (whether or not a lawsuit is 
filed), including, but not limited to, any attorneys' fees and costs 
(including attorneys' fees and expenses incurred pursuant to bankruptcy)

such action shall be entitled to recover its costs and attorneys' fees 
(including attorneys' fees and expenses incurred pursuant to bankruptcy), 
including (but not limited to) attorneys' fees and costs incurred in the 
enforcement of, execution upon or defense of any order, decree, award or 
judgment.  Borrower shall also pay Coast's standard charges for returned

HOWEVER, that Borrower may not assign or transfer any of its rights under 
this Agreement without the prior written consent of Coast, and any prohibited 
assignment shall be void.  No consent by Coast to any assignment shall

its rights and delegate its duties hereunder by the sale of assignment or 
participation interests, all without the consent of Borrower.

paragraph, and the headings shall not be used in any manner to construe, 
limit, define or interpret any term or provision of this Agreement.  The term 
"including", whenever used in this Agreement, shall mean "including (but not 
limited to)".  This Agreement has been fully reviewed and negotiated between 
the parties and no uncertainty or ambiguity in any term or provision of this 
Agreement shall be construed strictly against Coast or Borrower under any 
rule of construction or otherwise.

     11.16 GOVERNING LAW; JURISDICTION; VENUE. This Agreement and all acts 
and transactions hereunder and all rights and obligations of Coast and 
Borrower shall be governed by the internal laws of the State of California, 
without regard to its conflicts of law principles.  As a material part of the 
consideration to Coast to enter into this Agreement, Borrower (a) agrees that 
all actions and proceedings relating directly or indirectly to this Agreement 
shall, at Coast's option, be litigated in courts located within California, 
and that the exclusive venue therefor shall be Los Angeles County; (b) 
consents to the jurisdiction and venue of any such court and consents to 
service of process in any such action or proceeding by personal delivery or 
any other method permitted by law; and (c) waives any and all rights Borrower 
may have to object to the jurisdiction of any such court, or to transfer or 
change the venue of any such action or proceeding.

THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING 
OUT OF, OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR

     This Common Stock and Warrant Purchase Agreement (the "AGREEMENT") is made
as of the 27th day of February, 1998 by and between Centura Software
Corporation, a California corporation (the "COMPANY") and the investors listed
on EXHIBIT A attached hereto (each a "PURCHASER" and together the "PURCHASERS").

     The parties hereby agree as follows:

     1.   PURCHASE AND SALE OF COMMON STOCK AND WARRANTS.

          1.1  SALE AND ISSUANCE OF COMMON STOCK AND WARRANTS. Subject to the
terms and conditions of this Agreement, each Purchaser agrees to purchase at the
Closing and the Company agrees to sell and issue to each Purchaser at the
Closing that number of shares of Common Stock indicated with respect to such
Purchaser on EXHIBIT A attached hereto at a purchase price of $1.06 per share
and a warrant in the form attached hereto as EXHIBIT B to purchase that number
of shares of Common Stock indicated with respect to such Purchaser on EXHIBIT A
at a purchase price of $1.25 per share of Common Stock issuable upon exercise of
the warrant.  The shares of Common Stock  and the warrants issued to the
Purchaser pursuant to this Agreement shall be hereinafter referred to as the
"STOCK" and the "WARRANTS," respectively, and the shares of Common Stock
issuable upon exercise of the Warrants shall be hereinafter referred to as the
"WARRANT STOCK."  The Stock, the Warrants and the Warrant Stock shall be
hereinafter referred to as the "SECURITIES."

          1.2  CLOSING; DELIVERY.

               (a)  The purchase and sale of the Stock and the Warrants shall
take place on February __, 1998, or at such other time as the Company and the

               (b)  At the Closing, each Purchaser shall cause the purchase
price of the Stock and the Warrants being purchased to be delivered to the
escrow agent as provided in the Escrow Agreement attached hereto as Exhibit E

the Stock being purchased by each Purchaser and a Warrant for each Purchaser
exercisable for the applicable number of shares of Common Stock of the Company
for such Purchaser to be delivered to the escrow agent as provided in the Escrow
Agreement.  Upon the satisfaction of all the conditions set forth in Sections 6
and 7 hereof, the escrow agent shall be instructed to release the purchase price
to the Company, and the certificate representing the Stock and the Warrants to
each Purchaser all in accordance with the terms of the Escrow Agreement.

     2.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company hereby
represents and warrants to each Purchaser that, except as set forth on a

          2.1  ORGANIZATION, GOOD STANDING AND QUALIFICATION.  The Company is a

or Bylaws of the Company, or any agreement to which the Company is a party or by
which it is bound and are free of any liens or encumbrances other than any liens
or encumbrances created by or imposed upon the holders thereof.  The Company is
concurrently with the Closing of the issuance and sale of the Securities
hereunder closing an agreement providing for the conversion of approximately
$12.2 million of outstanding indebtedness into shares of Common Stock of the
Company at a conversion price of $1.06 per share.  The Company has also reserved
(i) an aggregate of 2,000,000 shares of Common Stock issuable to employees and
consultants pursuant to the Company's 1995 Stock Option Plan, of which 1,164,947
shares are issuable upon exercise of outstanding options under such plan, (ii)
an aggregate of 2,657,399 shares of Common Stock issuable to employees and
consultants pursuant to the Company's 1986 Stock Option Plan, of which 2,657,399
shares are issuable upon exercise of outstanding options under such plan,
(iii) an aggregate of 400,000 shares of Common Stock issuable to employees
pursuant to the Company's 1992 Employee Stock Purchase Plan, of which no shares
are available for future issuance under such plan, (iv) 500,000 shares of Common
Stock issuable to non-employee directors pursuant to Company's 1996 Directors'
Stock Option Plan, of which 300,000 shares are issuable upon exercise of

Company's Chief Executive Officer, Chief Financial Officer and Vice President of
Marketing to purchase up to an aggregate of 1,500,000 shares of Common Stock,
(vi) up to 450,000 shares of Common Stock issuable upon exercise of warrants
granted or to be granted to certain third parties, including vendors, suppliers
and financial and investment advisors of the Company, prior to inclusion of the
shares of Common Stock issuable upon exercise of the Warrants being purchased
and sold hereunder and a Warrant being issued to Computer Associates
International, Inc. concurrently on the date of the Closing.

          2.3  AUTHORIZATION.  All corporate action on the part of the Company,
its officers, directors and shareholders necessary for the authorization,
execution and delivery of this Agreement and the Warrants (collectively, the
"TRANSACTION AGREEMENTS"), the performance of all obligations of the Company
hereunder and thereunder and the authorization, issuance and delivery of the
Securities has been taken or will be taken prior to the Closing, and the
Transaction Agreements, when executed and delivered by the Company, shall
constitute valid 


                                      -2-


<PAGE>

and legally binding obligations of the Company, enforceable
against the Company in accordance with their terms except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance, and other laws of general application affecting enforcement of
creditors' rights generally, as limited by laws relating to the availability of
specific performance, injunctive relief, or other equitable remedies, or (ii) to
the extent the indemnification provisions contained in Section 4(g) herein below
may be limited by applicable federal or state securities laws.

          2.4  VALID ISSUANCE OF SECURITIES.  The Stock and the Warrants that
are being issued to the Purchasers hereunder, when issued and paid for in
accordance with this Agreement, and the shares of Common Stock issuable upon
exercise of the Warrants, when issued and paid for in accordance with the
Warrants, will be validly issued, fully paid, and nonassessable, and not subject
to any preemptive rights or rights of first refusal under applicable law, the
Articles of Incorporation or Bylaws of the Company, or any agreement to which
the Company is a party or by which the Company is bound, and are free of any
liens or encumbrances other than liens or encumbrances created by or imposed
upon the holders thereof; provided, however, that the Warrants (and the shares
of Common Stock issuable upon exercise thereof) may be subject to restrictions
on transfer as set forth in this Agreement, the Warrants, the Registration
Statement on Form S-3 to be filed with the Securities and Exchange Commission
pursuant to Section 4 hereunder, (the "RIGHTS AGREEMENT"), or the Articles of
Incorporation or Bylaws of the Company.  Based in part upon the representations
of the Purchasers in this Agreement, the Stock and the Warrants will be issued
in compliance with all applicable federal and state securities laws.

          2.5  LITIGATION.  There is no action, suit, proceeding or
investigation pending or, to the Company's knowledge, currently threatened
against the Company or any of its subsidiaries that is not disclosed in the
Reports (as defined in Section 2.6 below) and that would have a material adverse
effect on the Company or that questions the validity of the Transaction
Agreements or the right of the Company to enter into them, or to consummate the
transactions contemplated thereby.

          2.6  COMPLIANCE WITH OTHER INSTRUMENTS.  The execution, delivery and
performance of the Transaction Agreements and the consummation of the
transactions contemplated thereby will not result in any violation or default of
any provisions of the Articles of Incorporation or Bylaws of the Company or of
any instrument, judgment, order, writ, decree or contract to which the Company
is a party or by which the Company is bound or, to the Company's knowledge, of
any provision of federal or state statute, rule or regulation applicable to the
Company, or be in conflict with or constitute, with or without the passage of
time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an event which results
in the creation of any lien, charge or encumbrance upon any assets of the
Company.

          2.7  SEC REPORTS.  The Company has filed with the Securities and
Exchange Commission (the "COMMISSION") via Edgar its Annual Report on Form 10-K
for the year ended December 31, 1996 and its Quarterly Reports on Form 10-Q for
the first three quarters of the 


                                      -3-


<PAGE>

year ended December 31, 1997 (the "REPORTS"), and such Reports are available 
to Purchaser through Edgar in electronic format. As of their respective 
filing dates, the Reports complied in all material respects with the 
requirements of the Securities Exchange Act of 1934, as amended, and none of 
the Reports contained any untrue statement of a material fact or omitted to 
state a material fact required to be stated therein or necessary to make the 
statements made therein, in light of the circumstances in which they were 
made, not misleading, except to the extent corrected by a document 
subsequently filed with the Commission and provided to Purchaser prior to the 
date hereof.

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

          3.1  AUTHORIZATION.  Such Purchaser has full power and authority to
enter into this Agreement.  The Transaction Agreements, when executed and
delivered by the Purchaser, will constitute valid and legally binding
obligations of the Purchaser, enforceable in accordance with their terms, except
(a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent conveyance, and any other laws of general application affecting
enforcement of creditors' rights generally, and as limited by laws relating to
the availability of a specific performance, injunctive relief, or other
equitable remedies, or (b) to the extent the indemnification provisions
contained in Section 4(g) herein below may be limited by applicable federal or
state securities laws.

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

          3.3  DISCLOSURE OF INFORMATION.  The Purchaser has had an opportunity
to discuss the Company's business, management, financial affairs and the terms
and conditions of the offering of the Stock and the Warrants with the Company's
management and has had an opportunity to review the Company's facilities.  The
Purchaser understands that such discussions, and any other written information
delivered by the Company to the Purchaser, were intended to describe the aspects
of the Company's business which it believes to be material. 

          3.4  RESTRICTED SECURITIES. The Purchaser understands that the
Securities are characterized as "restricted securities" under applicable U.S.
federal and state securities laws inasmuch as they are being acquired from the
Company in a transaction not involving a public offering and that, pursuant to
these laws and applicable regulations, the Purchaser must hold the 


                                      -4-


<PAGE>

Securities indefinitely unless they are registered with the Securities and 
Exchange Commission and qualified by state authorities, or an exemption from 
such registration and qualification requirements is available. The Purchaser 
further acknowledges that if an exemption from registration or qualification 
is available, it may be conditioned on various requirements including, but 
not limited to, the time and manner of sale, the holding period for the 
Securities, and on requirements relating to the Company which are outside of 
the Purchaser's control, and which the Company is under no obligation and may 
not be able to satisfy.  In this connection, Purchaser represents that it is 
familiar with SEC Rule 144, as presently in effect, and understands the 
resale limitations imposed thereby and by the Securities Act of 1933, as 
amended (the "SECURITIES ACT").

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

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

               (b)  Any legend set forth in the other Transaction Agreements.

               (c)  Any legend required by the Blue Sky laws of any state to the
extent such laws are applicable to the shares represented by the certificate so
legended.

          3.6  ACCREDITED INVESTOR.  The Purchaser is an accredited investor as
defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

     4.   REGISTRATION OF SECURITIES.

          (a)  As soon as possible after the Closing, the Company shall use its
reasonable best efforts to prepare and file a registration statement on Form S-3
(the "REGISTRATION STATEMENT") with the Commission under the Act to register the
resale of the Stock and the Warrant Stock (collectively, the "REGISTRABLE
SECURITIES") and thereafter shall use its best efforts to secure the
effectiveness of such Registration Statement.

          (b)  The Company shall pay all Registration Expenses (as defined
below) in connection with any registration, qualification or compliance
hereunder, and Purchaser or any transferee of the Registrable Securities (each,
a "HOLDER") shall pay all Selling Expenses (as defined below) and other expenses
that are not Registration Expenses relating to the Registrable Securities resold
by Holder. "Registration Expenses" shall mean all expenses, except for Selling
Expenses, incurred by the Company in complying with the registration provisions
herein 


                                      -5-


<PAGE>

described, including, without limitation, all registration, qualification
and filing fees, printing expenses, fees and disbursements of counsel for the
Company, blue sky fees and expenses and the expense of any special audits
incident to or required by any such registration.  "Selling Expenses" shall mean
all selling commissions, brokerage or underwriting fees and stock transfer taxes
applicable to the Registrable Securities and all fees and disbursements of
counsel for Holder.

          (c)  In the case of any registration effected by the Company pursuant
to these registration provisions, and subject to the limitations on registration
set forth in Section 4(d) below, the Company will use commercially reasonable
efforts to:  (i) keep such registration effective until the earlier of (A) two
(2) years after the date of the Closing or (B) such date as the Company shall be
satisfied that then-current Holders may sell all of their Registrable Securities
then outstanding within a three (3) month period; (ii) prepare and file with the
Commission such amendments and supplements to such Registration Statement and
the prospectus used in connection with such Registration Statement as may be
necessary to comply with the provisions of the Act with respect to the
disposition of all securities covered by such Registration Statement; (iii)
furnish such number of prospectuses and other documents incident thereto,
including any amendment of or supplement to the prospectus, as a Holder from
time to time may reasonably request; (iv) register and qualify the securities
covered by such Registration Statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions; (v) cause all such
Registrable Securities registered as described herein to be listed on each
securities exchange and quoted on each quotation service on which similar
securities issued by the Company are then listed or quoted; and (vi) otherwise
use commercially reasonable efforts to comply with all applicable rules and
regulations of the Commission.

          (d)  The Company may, by written notice to Holder, delay the filing or
effectiveness of, or suspend, the Registration Statement, and require that
Holder immediately cease sales of shares pursuant to such Registration Statement
in any period during which the Company is engaged in any activity or transaction
or preparations or negotiations for any activity or transaction ("COMPANY
ACTIVITY") that the Company desires to keep confidential for business reasons,
if the Company determines in good faith that the public disclosure requirements
imposed on the Company under the Act in connection with the Registration
Statement would require disclosure of the Company Activity; provided, however,
that (A) the Company shall use commercially reasonable efforts to minimize the
length of any such period of delay or suspension, (B) any such delay or
suspension shall be applied in the same manner to any other resale registration
statement then in effect, (C) no such suspension period shall extend longer than
forty-five (45) consecutive calendar days, (D) no such suspension period may be
imposed within forty-five (45) days following the completion of a prior
suspension period, and (E) the Company shall not impose suspension periods
which, in the aggregate, exceed ninety (90) days in any twelve (12) month
period.  If the Company delays or suspends the Registration Statement or
requires Holder to cease sales of shares pursuant to this Section 4(d), the
Company shall, as promptly as practicable following the termination of the
circumstance which entitled the 


                                      -6-


<PAGE>

Company to do so, take such actions as may be necessary to file or reinstate 
the effectiveness of the Registration Statement and/or give written notice to 
Holder authorizing it to resume sales pursuant to such Registration 
Statement.  If as a result thereof the prospectus included in the 
Registration Statement has been amended to comply with the requirements of 
the Act, the Company shall enclose such revised prospectus with the notice to 
Holders given pursuant to this Section 4(d), and Holder shall make no offers 
or sales of shares pursuant to the Registration Statement other than by means 
of such revised prospectus.

          (e)  If Holder shall propose to sell any Registrable Securities
pursuant to the Registration Statement, it shall notify the Company of its
intent to do so at least three (3) full business days prior to such sale, and
the provision of such notice to the Company shall conclusively be deemed to
establish an agreement by Holder to comply with the registration provisions
herein described.  Such notice shall be deemed to constitute a representation
that any information required to be included in the Registration Statement and
previously supplied by Holder is accurate as of the date of such notice.  When
Holder is entitled to sell and gives notice of its intent to sell in compliance
with the foregoing, the Company shall promptly, furnish to Holder a reasonable
number of copies of a supplement to or an amendment of such prospectus as may be
necessary so that, as thereafter delivered to the Holders of such shares, such
prospectus shall not include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in the light of the
circumstances then existing.  Holder agrees that the Company may impose a legend
setting forth the provisions of Sections 4(d) and 4(e) on the Registrable
Securities.

          (f)  With a view to making available to the holders the benefits of
Rule 144 promulgated under the Act and any other rule or regulation of the
Commission that may at any time permit Holder to sell Registrable Securities to
the public without registration or pursuant to a registration on Form S-3, the
Company hereby covenants and agrees to:  (i) make and keep public information
available, as those terms are understood and defined in Rule 144, at all times
after the closing; and (ii) file with the Commission in a timely manner all
reports and other documents required of the Company under the Act and Exchange
Act.

          (g)  Indemnification.

                    (i)  To the extent permitted by law, the Company will
indemnify and hold harmless Holder, any underwriter (as defined in the Act) for
Holder, its officers, directors, shareholders or partners and each person, if
any, who controls Holder or underwriter within the meaning of the Act or the
Exchange Act, against any losses, claims, damages, or liabilities to which they
may become subject under the Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages, or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "VIOLATION"):  (A) any untrue statement
or alleged untrue statement of a material fact contained in such Registration
Statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto or (B) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein not misleading; and the Company will
pay to each such Holder, 


                                      -7-


<PAGE>

underwriter or controlling person, as incurred, any legal or other expenses 
reasonably incurred by them in connection with investigating or defending any 
such loss, claim, damage, liability, or action; provided, however, that the 
indemnity agreement contained in this Section 4(g)(i) shall not apply to 
amounts paid in settlement of any such loss, claim, damage, liability, or 
action if such settlement is effected without the consent of the Company 
(which consent shall not be unreasonably withheld), nor shall the Company be 
liable in any such case for any such loss, claim, damage, liability, or 
action to the extent that it arises out of or is based upon a Violation which 
occurs in reliance upon and in conformity with written information furnished 
expressly for use in connection with such registration by any such Holder, 
underwriter or controlling person; further provided, however, that the 
foregoing indemnity with respect to any untrue statement in or omission from 
any preliminary prospectus shall not inure to the benefit of any Holder from 
whom the person asserting any such losses, claims, damages or liabilities 
purchased the Registrable Securities if a copy of the final prospectus or any 
amendment thereto had not been sent or given to such person at or prior to 
the written confirmation of the sale of such Registrable Securities to such 
person if required by the Act and the untrue statement or omission of a 
material fact contained in such preliminary prospectus was corrected in the 
final prospectus or amendment and such final prospectus or amendment was 
distributed to the Holder prior to such sale of Registrable Securities.

                    (ii) To the extent permitted by law, each selling Holder
will indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the Registration Statement, each person, if any, who
controls the Company within the meaning of the Act, any underwriter, any other
Holder selling securities in such Registration Statement and any controlling
person of any such underwriter or other Holder, against any losses, claims,
damages, or liabilities to which any of the foregoing persons may become
subject, under the Act, the Exchange Act or other federal or state law, insofar
as such losses, claims, damages, or liabilities (or actions in respect thereto)
arise out of or are based upon any Violation, in each case to the extent (and
only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by such Holder expressly for use
in connection with such registration; and each such Holder will pay, as
incurred, any legal or other expenses reasonably incurred by any person intended
to be indemnified pursuant to this subsection 4(g)(ii), in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this
subsection 4(g)(ii) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder, which consent shall not be unreasonably withheld;
provided, that, in no event shall any indemnity under this subsection 4(g)(ii)
exceed the net proceeds from the offering received by such Holder, except in the
case of willful fraud by such Holder.

                    (iii) Promptly after receipt by an indemnified party
under this Section 4(g) of notice of the commencement of any action (including
any governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 4(g),
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly 


                                      -8-

noticed, to assume the defense thereof with counsel mutually satisfactory to 
the parties; provided, however, that an indemnified party (together with all 
other indemnified parties which may be represented without conflict by one 
counsel) shall have the right to retain one separate counsel, with the 
reasonable fees and expenses to be paid by the indemnifying party, if 
representation of such indemnified party by the counsel retained by the 
indemnifying party would be inappropriate due to actual or potential 
differing interests between such indemnified party and any other party 
represented by such counsel in such proceeding.  The failure to deliver 
written notice to the indemnifying party within a reasonable time of the 
commencement of any such action, if prejudicial to its ability to defend such 
action, shall relieve such indemnifying party of any liability to the 
indemnified party under this Section 4(g).      

     5.   RESALE RESTRICTIONS.  Holder agrees that it will not sell any 
Registrable Securities issued hereunder until the effectiveness of the 
Registration Statement to be filed pursuant to Section 4 above.  
Notwithstanding the foregoing, the Company may suspend resales by the Holder 
if an underwriter reasonably determines that such resales would adversely 
affect the Company's ability to raise additional capital in a public offering 
of the Company's equity securities and such underwriter issues a written 
opinion to the Company to that effect.  Any such suspension of resales by the 
Holder pursuant to the foregoing sentence will not exceed 120 calendar days 
commencing on the date of the secondary offering.  The volume and resale 
restrictions set forth in this Section 5 shall be set forth in any and all 
Registration Statements brought effective pursuant to Section 4 above, and 
the Company shall instruct its transfer agent, broker dealers and market 
makers to enforce the volume restrictions set forth herein.

power or remedy accruing to any party under this Agreement, upon any breach or
default of any other party under this Agreement, shall impair any such right,
power or remedy of such non-breaching or non-defaulting party nor shall it be
construed to be a waiver of any such breach or default, or an acquiescence
therein, or of or in any similar breach or default thereafter occurring; nor
shall any waiver of any single breach or default be deemed a waiver of any other
breach or default theretofore or thereafter occurring.  Any waiver, permit,
consent or approval of any kind or character on the part of any party of any
breach or default under this Agreement, or any waiver on the part of any party
of any provisions or conditions of this Agreement, must be in writing and shall
be effective only to the extent specifically set forth in such writing.  All
remedies, either under this Agreement or by law or otherwise afforded to any
party, shall be cumulative and not alternative.

herein constitute the entire agreement between the parties hereto pertaining to
the subject matter hereof, and any and all other written or oral agreements
relating to the subject matter hereof existing between the parties hereto are
expressly canceled.

          8.13 CORPORATE SECURITIES LAW.  THE SALE OF THE SECURITIES WHICH ARE
THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF
CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF THE SECURITIES OR

QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM THE
QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS
CODE.  THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED
UPON THE QUALIFICATION BEING OBTAINED UNLESS THE SALE IS SO EXEMPT.

prior written permission of the other party, it shall at all times keep
confidential and not divulge, furnish or make accessible to anyone any
confidential information, knowledge or data concerning or relating to the
business or financial affairs of the other parties to which such party has been
or shall become privy by reason of this Agreement, discussions or negotiations
relating to this Agreement, the performance of its obligations hereunder or the
ownership of Stock or Warrants purchased hereunder.  The provisions of this

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

         3.1  AUTHORIZATION.  The execution, delivery and performance by the 
Purchaser of the Transaction Agreements are within the Purchaser's limited 
liability company power and have been duly authorized by all requisite action 
by the Purchaser.  The Transaction Agreements have been duly executed and 
delivered by the Purchaser and this Agreement constitutes, and the Rights 
Agreement when executed and delivered in accordance with this Agreement will 
constitute, the valid and binding obligation of the Purchaser, enforceable in 
accordance with their respective terms, except as such enforceability may be 
limited by principles of public policy and subject to the laws of general 
application relating to bankruptcy, insolvency and the relief of debtors and 
rules of law governing specific performance, injunctive relief or other 
equitable remedies.

         3.2  PURCHASE ENTIRELY FOR OWN ACCOUNT.  The Purchaser is acquiring 
the shares of Conversion Stock hereunder for investment for the Purchaser's 
own account, and not as a nominee or agent, and not with a view to the resale 
or distribution of any part thereof.  Purchaser has no present intention of 
selling, granting any participation in, or otherwise distributing the 
Securities other than to members of the Purchaser as of the date hereof.

         3.3  ACCREDITED INVESTOR.  The Purchaser is an accredited investor 
as defined in Rule 501(a) of Regulation D promulgated under the 1933 Act.


                                       -8-

<PAGE>

          3.4  RESTRICTED SECURITIES.  Purchaser understands that the Securities
are characterized as "restricted securities" under the federal securities laws
inasmuch as they are being acquired from the Company in a transaction not
involving a public offering and that under such laws and applicable regulations
such Securities may be resold without registration under the 1933 Act, only in
certain limited circumstances.  In this connection, Purchaser represents that it
is familiar with SEC Rule 144, as presently in effect, and understands the
resale limitations imposed thereby and by the Act.

          3.5  FURTHER LIMITATIONS ON DISPOSITION.  Notwithstanding anything to
the contrary contained in Section 3.5 of the Purchase Agreement, without in any
way limiting the representations set forth in this Agreement, Purchaser further
agrees not to make any disposition of all or any portion of the Securities
unless and until:

              (a)  There is then in effect a Registration Statement under the 
1933 Act covering such proposed disposition and such disposition is made in 
accordance with such Registration Statement; or

              (b)  (i) Purchaser shall have notified the Company of the 
proposed disposition and shall have furnished the Company with such 
information as is necessary to effect the proposed disposition, (ii) the 
transferee has agreed in writing for the benefit of the Company to be bound 
by this Section 3, and (iii) if reasonably requested by the Company, 
Purchaser shall have furnished the Company with an opinion of counsel, 
reasonably satisfactory to the Company, that such disposition will not 
require registration under the 1933 Act.

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

              (a)  "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE 
SECURITIES ACT OF 1933.  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR 
HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH 
RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL REASONABLY 
SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED OR UNLESS 
SOLD PURSUANT TO RULE 144 OF SUCH ACT."

              (b)  Any legend required by the laws of the State of 
California, including any legend required by the California Department of 
Corporations.

              (c)  Any legend required by the Blue Sky laws of any other 
state to the extent such laws are applicable to the shares represented by the 
certificate so legended.

              (d)  Any legend required by the Company's Shareholder Rights 
Plan.

The legends set forth in subparagraphs (a), (b) and (c) above shall be 
removed upon application to the Company after the one year anniversary date 
of this Agreement and the Company shall


                                       -9-

<PAGE>

promptly issue a certificate without such legends to the holder of Securities 
upon which it is stamped and shall remove all stop transfer orders and other 
transfer restrictions communicated to the Company's transfer agent, if (i) 
such Securities are registered for sale under the 1933 Act, (ii) in 
connection with a sale transaction, such holder provides the Company with an 
opinion of counsel, in a generally acceptable form, to the effect that a 
public sale, assignment or transfer of the Securities may be made without 
registration under the 1933 Act or (iii) such holder provides the Company 
with reasonable assurances that the Securities can be sold pursuant to Rule 
144 and the Company's counsel has reasonably determined that the legends set 
forth in subparagraphs (a), (b) and (c) above may be removed under Rule 144; 
provided however, that in the event Purchaser is granted piggy-back 
registration rights in connection with an equity offering by the Company 
prior to the one year anniversary date of this Agreement, the legends set 
forth in subparagraphs (a), (b) and (c) above shall be removed upon 
application to the Company and the Company shall issue a certificate without 
such legends to the holder of Securities upon which it is stamped.

         3.7  DISCLOSURE OF INFORMATION.  Purchaser has had an opportunity to 
discuss the Company's business, management, financial affairs and the terms 
and conditions of the offering of the Securities with the Company's 
management and has had an opportunity to review the Company's Reports.  
Purchaser understands that such discussions, as well as the written

the Company's business which it believes to be material.

meeting of shareholders, the Company shall recommend in such proxy materials 
that shareholders at each such meeting elect two (2) individuals to its Board 
of Directors who were nominated by the Purchaser (or the holders of a

that shareholders at each such meeting elect one (1) individual to its Board

of the Conversion Stock if the Purchaser has been dissolved) and the Company 
shall at each such meeting cause its designated proxyholder to vote proxies 
received from shareholders in favor of such nominee, provided that such 
nominee is reasonably acceptable to the Company.  In the event the Company 
increases its Board size above seven (7) directors prior to the next annual 
meeting of shareholders, the Company shall not be required to nominate or 
recommend election of additional Purchaser candidates to the Company's Board 
of Directors other than as set forth above in this Section 5.1, provided that

         5.2  BYLAWS AMENDMENTS. On or before the Closing date, effective

other corporation in which securities possessing more than fifty percent 
(50%) of the total combined voting power of the Company's outstanding 
securities are transferred to a person or persons different from the persons 
holding those securities immediately prior to such transaction (other than a 
consolidation or merger in which the surviving entity is the Company or one 
of its wholly-owned subsidiaries) or transfer or sale of all or substantially 
all of the assets of the Company; or

              (ii) an increase in the Company's secured indebtedness to an

the holders of a majority of the Conversion Stock if the Purchaser has been 
dissolved) so long as the Purchaser and/or one or more of the persons listed 
on EXHIBIT F continues to hold at least 7.5% of the issued and outstanding 
capital stock of the Company.

         5.3  AMENDMENT TO PREFERRED SHARES RIGHTS AGREEMENT.  On or before 
the Closing Date, the Company shall have taken all appropriate action to 
ensure that (a) the sale of the Conversion Stock to Purchaser hereunder is 
not deemed to be a Triggering Event as that term is defined in Section 1(y) 
of the Preferred Shares Rights Agreement dated August 3, 1994 between the 
Company and Chemical Trust Company of California (the "RIGHTS PLAN"), (b) 
neither the Purchaser nor any of its members, Affiliates, Associates, 
representatives or control persons shall be deemed an "Acquiring Person" 
under the Rights Plan and (c) the Purchaser nominees to the Board of 
Directors shall be deemed "Continuing Directors" under the Rights Plan.

         5.4  FORM D AND BLUE SKY.  The Company agrees to file a Form D with 
respect to the Conversion Stock as required under Regulation D and to provide 
a copy thereof to the Purchaser promptly after such filing.  The Company 
shall, on or before the Closing Date, take such action as the Company shall 
reasonably determine is necessary to qualify the Conversion Stock for, or 
obtain exemption for the Conversion Stock for, sale to the Purchaser at the 
Closing pursuant to this Agreement under applicable securities or "Blue Sky" 
laws of the states of the United States, and shall provide evidence of any 
such action so taken to the Purchaser on or prior to the Closing Date.  The 
Company shall make all filings and reports relating to the offer and sale of 
the Conversion Stock required under applicable securities or "Blue Sky" laws 
of applicable states of the United States following the Closing Date.

         5.5  REPORTING STATUS.  Until the date as of which the Holders (as 
that term is defined in the Rights Agreement) may sell all of the Conversion 
Shares without restriction pursuant to Rule 144(k) promulgated under 1933 Act 
(or successor thereto), the Company shall file all reports required to be 
filed with the SEC pursuant to the Securities Exchange Act of 1934, as 
amended (the "1934 ACT"), and until that date, the Company shall not 
terminate its status as an issuer required to file reports under the 1934 Act 
even if the 1934 Act, or the rules and regulations thereunder would otherwise 
permit such termination, unless the reporting requirements of Rule 144(k) 
have also been amended to permit the Holders to sell the Conversion Shares 
without restriction.

         5.6  FINANCIAL INFORMATION.  The Company shall file with the SEC via 
Edgar all registration statements and all reports required pursuant to the

made available or given to the shareholders of the Company generally, 
contemporaneously with the making available or giving thereof to the 
shareholders.

         5.7  LISTING.  The Company shall use its best efforts to maintain 
the inclusion for quotation on The Nasdaq SmallCap Market of its Common 
Stock, and without limiting the generality of the foregoing, the Company 
shall use its best efforts to arrange for at least two market makers to 
register with the NASD or any other comparable exchange as such with respect 
to the Common Stock.  The Company shall not knowingly take any action which 
would be


                                       -12-

<PAGE>

reasonably expected to result in the removal of the Common Stock from 
quotation on The Nasdaq SmallCap Market.  At such time as the Company is able 
to satisfy the listing requirements on the Nasdaq National Market System 
("NNM") and the Company's management reasonably believes that the Company 
will be able to continue to comply with the continued listing requirements of 
the NNM thereafter, the Company shall use its reasonable efforts to secure 
designation and quotation of its outstanding Common Stock on the NNM.  The 
Company shall promptly report to its Board of Directors information or 
notices it receives regarding the continued eligibility of its Common Stock 
for quotation on any automated quotation system or securities exchange.

         5.8  FILING OF FORM 8-K.  Within five (5) business days following 
the Closing Date, the Company shall file a Form 8-K with the SEC describing 
the terms of the transactions contemplated by the Transaction Agreements and

transactions contemplated hereunder, the Company will consummate a private 
placement of Common Stock of the Company, at not less than $1.06 per share

share), resulting in gross proceeds to the Company of at least $1,000,000.

         5.10 COAST CONSENT.  The Company shall have obtained from Coast, as 
a condition to the Closing, a written consent by Coast to the Company's 
execution, delivery and performance of the Transaction Agreements and a 
waiver, effective upon the Closing, of any defaults by the Company under its 
debt facility with Coast occurring prior to the Closing Date.

         (b)  reincorporation of the Company into Delaware; and

         (c)  an increase in the total number of authorized shares of the 
Company's Common Stock, provided however that the Purchaser shall not be

advisors of the Company, prior to inclusion of the shares of Common Stock 
issuable upon exercise of the Warrant being purchased and sold hereunder.  
The Warrant, when issued and paid for in accordance with this Agreement, and 
the shares of Common Stock issuable upon exercise thereof, when issued and 
paid for in accordance with the Warrant, will be validly issued, fully paid, 
and nonassessable, and not subject to any preemptive rights or rights of 
first refusal under applicable law, the Articles of Incorporation or Bylaws 
of the Company, or any agreement to which the Company is a party or by which 
the Company is bound, and are free of any liens or encumbrances other than 
liens or encumbrances created by or imposed upon the holders thereof; 
provided, however, that the Warrant (and the shares of Common Stock issuable 
upon exercise thereof) may be subject to restrictions on transfer as set 
forth in this Agreement, the Warrant, the Registration Statement on Form S-3 
to be filed with the Securities and Exchange Commission pursuant to Section 4 
hereunder, (the "RIGHTS AGREEMENT"), or the Articles of Incorporation or 
Bylaws of the Company.

          2.3  AUTHORIZATION.  The execution, delivery and performance by the 
Company of this Agreement, the Escrow Agreement, the Warrant and the Rights 
Agreement (collectively, the "TRANSACTION AGREEMENTS") are within the 
Company's corporate power and have been duly authorized by all requisite 
action by the Company.  The Transaction Agreements have been duly executed 
and delivered by the Company and this Agreement constitutes, and the Escrow 
Agreement, the Warrant and Rights Agreement when executed and delivered in 
accordance with this Agreement, will constitute the valid and binding 
obligation of the Company, enforceable in accordance with their respective 
terms, except as such enforceability may be limited by principles of public 
policy and subject to the laws of general application relating to bankruptcy, 
insolvency and the relief of debtors and rules of law governing specific 
performance, injunctive relief or other equitable remedies.

          2.4  LITIGATION.  There is no action, suit, proceeding or 
investigation pending or, to the Company's knowledge, currently threatened 
against the Company or any of its subsidiaries that is not disclosed in the 
Reports and that would have a material adverse effect on the Company or that 
questions the validity of the Transaction Agreements or the right of the 
Company to enter into them, or to consummate the transactions contemplated 
thereby.

          2.5  COMPLIANCE WITH OTHER INSTRUMENTS.  The execution, delivery 
and performance of the Transaction Agreements and the consummation of the 
transactions contemplated thereby will not result in any violation or default 
of any provisions of the Articles of Incorporation or Bylaws of the Company 
or of any instrument, judgment, order, writ, decree or contract to which the 
Company is a party or by which the Company is bound or, to the Company's 
knowledge, of any provision of federal or state statute, rule or regulation 
applicable to the Company, or be in conflict with or constitute, with or 
without the passage of time and giving of notice, either a default under any 
such provision, instrument, judgment, order, writ, decree or contract or an 
event which results in the creation of any lien, charge or encumbrance upon 
any assets of the Company.

          2.6  SEC REPORTS.  The Company has filed with the Securities and
Exchange Commission (the "COMMISSION") via Edgar its Annual Report on Form 10-K
for the year ended

                                      -3-
<PAGE>

December 31, 1996 and its Quarterly Reports on Form 10-Q for the first three 
quarters of the year ended December 31, 1997 (the "REPORTS"), and such 
Reports are available to CA through Edgar in electronic format.  As of their 
respective filing dates, the Reports complied in all material respects with 
the requirements of the Securities Exchange Act of 1934, as amended, and none 
of the Reports contained any untrue statement of a material fact or omitted 
to state a material fact required to be stated therein or necessary to make 
the statements made therein, in light of the circumstances in which they were 
made, not misleading, except to the extent corrected by a document 
subsequently filed with the Commission and provided to CA prior to the date 
hereof.

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

          3.1  AUTHORIZATION.  The execution, delivery and performance by CA 
of the Transaction Agreements are within CA's corporate power and have been 
duly authorized by all requisite action by CA.  The Transaction Agreements 
have been duly executed and delivered by CA and this Agreement constitutes, 
and the Escrow Agreement, the Warrant and the Rights Agreement when executed 
and delivered in accordance with this Agreement, will constitute the valid 
and binding obligation of the CA, enforceable in accordance with their 
respective terms, except as such enforceability may be limited by principles 
of public policy and subject to the laws of general application relating to 
bankruptcy, insolvency and the relief of debtors and rules of law governing 
specific performance, injunctive relief or other equitable remedies.

          3.2  PURCHASE ENTIRELY FOR OWN ACCOUNT.  CA is acquiring the 
Warrant (and the shares of Common Stock issuable upon exercise thereof (the 
"WARRANT STOCK", together with the Warrant, the "Securities")) hereunder for 
investment for CA's own account, and not as a nominee or agent, and not with 
a view to the resale or distribution of any part thereof.  CA has no present 
intention of selling, granting any participation in, or otherwise 
distributing the foregoing.

          3.3  ACCREDITED INVESTOR.  CA is an accredited investor as defined 
in Rule 501(a) of Regulation D promulgated under the Securities Act.

          3.4  RESTRICTED SECURITIES.  CA understands that the Warrant and 
the Warrant Stock are characterized as "restricted securities" under the 
federal securities laws inasmuch as they are being acquired from the Company 
in a transaction not involving a public offering and that under such laws and 
applicable regulations such Warrant and the Warrant Stock may be resold 
without registration under the Securities Act of 1933, as amended (the 
"ACT"), only in certain limited circumstances.  In this connection, CA 
represents that it is familiar with SEC Rule 144, as presently in effect, and 
understands the resale limitations imposed thereby and by the Act.

          3.5  FURTHER LIMITATIONS ON DISPOSITION.  Without in any way 
limiting the representations set forth above, CA further agrees not to make 
any disposition of all or any portion of the Warrant and the Warrant Stock 
unless and until:

                                      -4-
<PAGE>

               (a)  There is then in effect a Registration Statement under 
the Act covering such proposed disposition and such disposition is made in 
accordance with such Registration Statement; or

               (b)  (i) The transferee has agreed in writing for the benefit 
of the Company to be bound by this Section 3; (ii) CA shall have notified the 
Company of the proposed disposition and shall have furnished the Company with 
such information as is necessary to effect the proposed disposition, and 
(iii) if reasonably requested by the Company, CA shall have furnished the 
Company with an opinion of counsel, reasonably satisfactory to the Company, 
that such disposition will not require registration under the Act.

          3.6  LEGENDs.  CA understands that the Warrant and the Warrant 
Stock, and any securities issued in respect thereof or exchange therefor, may 
bear one or all of the following legends:

               (a)  "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE 
SECURITIES ACT OF 1933.  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR 
HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH 
RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL REASONABLY 
SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED OR UNLESS 
SOLD PURSUANT TO RULE 144 OF SUCH ACT."

               (b)  Any legend required by the laws of the State of 
California, including any legend required by the California Department of 
Corporations.

               (c)  Any legend required by the Blue Sky laws of any other 
state to the extent such laws are applicable to the shares represented by the 
certificate so legended.

               (d)  Any legend referring to the Company's Shareholder Rights 
Plan.

          3.7  DISCLOSURE OF INFORMATION.  CA has had an opportunity to 
discuss the Company's business, management, financial affairs and the terms 
and conditions of the offering of the Warrant and the Warrant Stock with the 
Company's management and has had an opportunity to review the Company's 
Reports. CA understands that such discussions, as well as the written 
information issued by the Company, were intended to describe the aspects of 
the Company's business which it believes to be material.

     4.   REGISTRATION OF SECURITIES.

          (a)  As soon as reasonably practicable after the Closing, but in no 
event later than 60 days after the Closing, the Company shall use its 
reasonable efforts to prepare and file a registration statement on Form S-3 
(the "REGISTRATION STATEMENT") with the Commission under the Act to register 
the resale of the Common Stock issuable upon exercise of the Warrant  
("REGISTRABLE SECURITIES") and thereafter shall use its best efforts to 
secure the effectiveness of such Registration Statement as soon as possible 
and to maintain its effectiveness thereafter.

                                      -5-
<PAGE>

          (b)  The Company shall pay all Registration Expenses (as defined 
below) in connection with any registration, qualification or compliance 
hereunder, and CA or any transferee of the Registrable Securities (each, a 
"HOLDER") shall pay all Selling Expenses (as defined below) and other 
expenses that are not Registration Expenses relating to the Registrable 
Securities resold by Holder. "Registration Expenses" shall mean all expenses, 
except for Selling Expenses, incurred by the Company in complying with the 
registration provisions herein described, including, without limitation, all 
registration, qualification and filing fees, printing expenses, fees and 
disbursements of counsel for the Company, blue sky fees and expenses and the 
expense of any special audits incident to or required by any such 
registration.  "Selling Expenses" shall mean all selling commissions, 
brokerage or underwriting fees and stock transfer taxes applicable to the 
Registrable Securities and all fees and disbursements of counsel for Holder.

          (c)  In the case of any registration effected by the Company 
pursuant to these registration provisions, and subject to the limitations on 
registration set forth in Section 4(d) below, the Company will use 
commercially reasonable efforts to:  (i) keep such registration effective 
until the earlier of (A) one (1) year after the date of the Closing or (B) 
such date as the Company shall be satisfied that then-current Holders may 
sell all of their Registrable Securities then outstanding within a three (3) 
month period; (ii) prepare and file with the Commission such amendments and 
supplements to such Registration Statement and the prospectus used in 
connection with such Registration Statement as may be necessary to comply 
with the provisions of the Act with respect to the disposition of all 
securities covered by such Registration Statement; (iii) furnish such number 
of prospectuses and other documents incident thereto, including any amendment 
of or supplement to the prospectus, as a Holder from time to time may 
reasonably request; (iv) register and qualify the securities covered by such 
Registration Statement under such other securities or Blue Sky laws of such 
jurisdictions as shall be reasonably requested by the Holders, provided that 
the Company shall not be required in connection therewith or as a condition 
thereto to qualify to do business or to file a general consent to service of 
process in any such states or jurisdictions; (v) cause all such Registrable 
Securities registered as described herein to be listed on each securities 
exchange and quoted on each quotation service on which similar securities 
issued by the Company are then listed or quoted; and (vi) otherwise use 
commercially reasonable efforts to comply with all applicable rules and 
regulations of the Commission.

          (d)  The Company may, by written notice to Holder, delay the filing 
or effectiveness of, or suspend, the Registration Statement, and require that 
Holder immediately cease sales of shares pursuant to such Registration 
Statement in any period during which the Company is engaged in any activity 
or transaction or preparations or negotiations for any activity or 
transaction ("COMPANY ACTIVITY") that the Company desires to keep 
confidential for business reasons, if the Company determines in good faith 
that the public disclosure requirements imposed on the Company under the Act 
in connection with the Registration Statement would require disclosure of the 
Company Activity; provided, however, that (A) the Company shall use 
commercially reasonable efforts to minimize the length of any such period of 
delay or suspension, and (B) any such delay or suspension shall be applied in 
the same manner to any other resale registration statement then in effect.  
If the Company delays or suspends the

                                      -6-
<PAGE>

Registration Statement or requires Holder to cease sales of shares pursuant 
to this Section 4(d), the Company shall, as promptly as practicable following 
the termination of the circumstance which entitled the Company to do so, take 
such actions as may be necessary to file or reinstate the effectiveness of 
the Registration Statement and/or give written notice to Holder authorizing 
it to resume sales pursuant to such Registration Statement.  If as a result 
thereof the prospectus included in the Registration Statement has been 
amended to comply with the requirements of the Act, the Company shall enclose 
such revised prospectus with the notice to Holders given pursuant to this 
Section 4(d), and Holder shall make no offers or sales of shares pursuant to 
the Registration Statement other than by means of such revised prospectus.

          (e)  If Holder shall propose to sell any Registrable Securities 
pursuant to the Registration Statement, it shall notify the Company of any 
such sale within one business day after such sale and the provision of such 
notice to the Company shall conclusively be deemed to establish an agreement 
by Holder to comply with the registration provisions herein described.  Such 
notice shall be deemed to constitute a representation that any information 
required to be included in the Registration Statement and previously supplied 
by Holder is accurate as of the date of such notice.  When Holder is entitled 
to sell and gives notice of its intent to sell in compliance with the 
foregoing, the Company shall promptly, furnish to Holder a reasonable number 
of copies of a supplement to or an amendment of such prospectus as may be 
necessary so that, as thereafter delivered to the Holders of such shares, 
such prospectus shall not include an untrue statement of a material fact or 
omit to state a material fact required to be stated therein or necessary to 
make the statements therein not misleading or incomplete in the light of the 
circumstances then existing.  Holder agrees that the Company may impose a 
legend setting forth the provisions of this Section 4(e) on the Registrable 
Securities.

          (f)  With a view to making available to the holders the benefits of 
Rule 144 promulgated under the Act and any other rule or regulation of the 
Commission that may at any time permit Holder to sell Registrable Securities 
to the public without registration or pursuant to a registration on Form S-3, 
the Company hereby covenants and agrees to:  (i) make and keep public 
information available, as those terms are understood and defined in Rule 144, 
at all times after the closing; and (ii) file with the Commission in a timely 
manner all reports and other documents required of the Company under the Act 
and Exchange Act.

          (g)  Indemnification.

                    (i)   To the extent permitted by law, the Company will 
indemnify and hold harmless Holder, any underwriter (as defined in the Act) 
for Holder, its officers, directors, shareholders or partners and each 
person, if any, who controls Holder or underwriter within the meaning of the 
Act or the Exchange Act, against any losses, claims, damages, or liabilities 
to which they may become subject under the Act, the Exchange Act or other 
federal or state law, insofar as such losses, claims, damages, or liabilities 
(or actions in respect thereof) arise out of or are based upon any of the 
following statements, omissions or violations (collectively a "VIOLATION"):  
(A) any untrue statement or alleged untrue statement of a material fact 
contained in such Registration Statement, including any preliminary 
prospectus or final prospectus contained therein or any amendments or 
supplements thereto or (B) the omission

                                      -7-
<PAGE>

or alleged omission to state therein a material fact required to be stated 
therein, or necessary to make the statements therein not misleading; and the 
Company will pay to each such Holder, underwriter or controlling person, as 
incurred, any legal or other expenses reasonably incurred by them in 
connection with investigating or defending any such loss, claim, damage, 
liability, or action; provided, however, that the indemnity agreement 
contained in this Section 4(g)(i) shall not apply to amounts paid in 
settlement of any such loss, claim, damage, liability, or action if such 
settlement is effected without the consent of the Company (which consent 
shall not be unreasonably withheld), nor shall the Company be liable in any 
such case for any such loss, claim, damage, liability, or action to the 
extent that it arises out of or is based upon a Violation which occurs in 
reliance upon and in conformity with written information furnished expressly 
for use in connection with such registration by any such Holder, underwriter 
or controlling person; further provided, however, that the foregoing 
indemnity with respect to any untrue statement  in or omission from any 
preliminary prospectus shall not inure to the benefit of any Holder from whom 
the person asserting any such losses, claims, damages or liabilities 
purchased the Registrable Securities if a copy of the final prospectus or any 
amendment thereto had not been sent or given to such person at or prior to 
the written confirmation of the sale of such Registrable Securities to such 
person if required by the Act and the untrue statement or omission of a 
material fact contained in such preliminary prospectus was corrected in the 
final prospectus or amendment and such final prospectus or amendment was 
distributed to the Holder prior to such sale of Registrable Securities.

                    (ii)  To the extent permitted by law, each selling Holder 
will indemnify and hold harmless the Company, each of its directors, each of 
its officers who has signed the Registration Statement, each person, if any, 
who controls the Company within the meaning of the Act, any underwriter, any 
other Holder selling securities in such Registration Statement and any 
controlling person of any such underwriter or other Holder, against any 
losses, claims, damages, or liabilities to which any of the foregoing persons 
may become subject, under the Act, the Exchange Act or other federal or state 
law, insofar as such losses, claims, damages, or liabilities (or actions in 
respect thereto) arise out of or are based upon any Violation, in each case 
to the extent (and only to the extent) that such Violation occurs in reliance 
upon and in conformity with written information furnished by such Holder 
expressly for use in connection with such registration; and each such Holder 
will pay, as incurred, any legal or other expenses reasonably incurred by any 
person intended to be indemnified pursuant to this subsection 4(g)(ii), in 
connection with investigating or defending any such loss, claim, damage, 
liability, or action; provided, however, that the indemnity agreement 
contained in this subsection 4(g)(ii) shall not apply to amounts paid in 
settlement of any such loss, claim, damage, liability or action if such 
settlement is effected without the consent of the Holder, which consent shall 
not be unreasonably withheld; provided, that, in no event shall any indemnity 
under this subsection 4(g)(ii) exceed the net proceeds from the offering 
received by such Holder, except in the case of willful fraud by such Holder.  

                    (iii) Promptly after receipt by an indemnified party 
under this Section 4(g) of notice of the commencement of any action 
(including any governmental action), such indemnified party will, if a claim 
in respect thereof is to be made against any indemnifying party under this 
Section 4(g), deliver to the indemnifying party a written notice of the 

                                      -8-
<PAGE>

commencement thereof and the indemnifying party shall have the right to 
participate in, and, to the extent the indemnifying party so desires, jointly 
with any other indemnifying party similarly noticed, to assume the defense 
thereof with counsel mutually satisfactory to the parties; provided, however, 
that an indemnified party (together with all other indemnified parties which 
may be represented without conflict by one counsel) shall have the right to 
retain one separate counsel, with the reasonable fees and expenses to be paid 
by the indemnifying party, if representation of such indemnified party by the 
counsel retained by the indemnifying party would be inappropriate due to 
actual or potential differing interests between such indemnified party and 
any other party represented by such counsel in such proceeding.  The failure 
to deliver written notice to the indemnifying party within a reasonable time 
of the commencement of any such action, if prejudicial to its ability to 
defend such action, shall relieve such indemnifying party of any liability to 
the indemnified party under this Section 4(g).

     5.   RESALE RESTRICTIONS.  Holder agrees that it will not sell any 
Registrable Securities issued hereunder until 90 calendar days after the 
Closing and the earlier to occur of; (i) effectiveness of the Registration 
Statement to be filed pursuant to Section 4 above; and (ii) the first 
anniversary of the issuance of the Warrant.  Holder further agrees that, 
notwithstanding anything in this Agreement to the contrary, the maximum 
number of Registrable Securities which may be sold by Holder in open market 
transactions on any day (including sales pursuant to Rule 144 under the Act) 
shall not exceed twenty-five percent (25%) of the average daily trading 
volume of the Company's Common Stock as calculated over the immediately 
preceding twenty (20) consecutive trading days. Notwithstanding the 
foregoing, the Company may suspend resales by the Holder pursuant to a 
Registration Statement if an underwriter reasonably determines that such 
resales would adversely affect the Company's ability to raise additional 
capital in a secondary offering of the Company's equity securities and such 
underwriter issues a written opinion to the Company to that effect. Any such 
suspension of resales by the Holder pursuant to the foregoing sentence will 
not exceed 120 calendar days commencing on the date of the secondary 
offering.   The volume and resale restrictions set forth in this Section 5 
shall be set forth in any and all Registration Statements brought effective 
pursuant to Section 4 above, and the Company shall instruct its transfer 
agent, broker dealers and market makers to enforce the volume restrictions 
set forth herein.

     6.   RELEASE OF CLAIMS.   

          6.1  RELEASE OF CLAIMS IN CONNECTION WITH THE NOTE.   In 
consideration for the obligations of the Company set forth in this Agreement, 
CA, on behalf of itself, and its respective officers, directors, employees, 
shareholders, attorneys, accountants, predecessor and successor corporations, 
affiliates, subsidiaries, representatives, transferees and assigns, hereby 
fully and forever releases the Company and its respective officers, 
directors, employees, shareholders, attorneys, accountants, predecessor and 
successor corporations, affiliates, subsidiaries, representatives, 
transferees and assigns from any claim, duty, obligation or cause of action 
relating to any matters of any kind, whether known or unknown, suspected or 
unsuspected, that it may possess arising from any omissions, acts or facts 
that have occurred up until and including the date of the Closing of this 
Agreement including, without limitation:

          (a)  any and all claims in connection with the Company's 
representations, warranties and covenants under the Note Purchase Agreement;

          (b)  any and all claims relating to or arising from CA's purchase 
of the Note from the Company and subsequent sale of the Note at a loss; and 

          (c)  any and all claims for attorney's fees and costs.

The Company and CA agree that the release set forth in this section shall be 
and remain in effect in all respects as a complete and general release as to 
the matters released.  This release does not extend to any obligations 
incurred under this Agreement.

          6.2. CIVIL CODE SECTION 1542.  The parties represent that they are 
not aware of any claim by either of them other than the claims that are 
released by this Agreement.  CA acknowledges that it is familiar with the 
provisions of California Civil Code Section 1542, which provides as follows:

          A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
          NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE
          RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
          SETTLEMENT WITH THE DEBTOR.

     CA, being aware of such code section, agrees to waive any rights it may 
have thereunder, as well as under any similar provision under New York state 
law, or other applicable state law, statute or common law principles of 
similar effect.

right, power or remedy accruing to any party under this Agreement, upon any 
breach or default of any other party under this Agreement, shall impair any

<PAGE>

     "Affiliate" shall mean any Person that directly or indirectly controls, 
is controlled by, or is under common control with such Person.  A Person

management or policies of the controlled Person, whether through ownership of 
stock or partnership or member interests, by contract, agreement or 
understanding (whether oral or written), or otherwise.

Agreement.

     "Exchange Act" shall mean the Securities Exchange Act of 1934, as 
amended.

     "Holders" shall mean Newport, each of the Persons listed on Schedule 1

     "Registrable Shares" shall mean the Common Shares and any shares of 
capital stock issued or issuable with respect to the Common Shares as a 
result of any stock split, stock dividend, recapitalization, exchange or 
similar event or otherwise.  As to any particular Registrable Share, such 
Registrable Share shall cease to be a Registrable Share when (w) it shall 
have been sold, transferred or otherwise disposed of or exchanged pursuant to 
a registration statement under the Securities Act; (x) it may be distributed 
to the public, together with all other Registrable Shares held by the Holder 
of such share, during any ninety (90) day period pursuant to and in 
compliance with all applicable requirements of Rule 144 (or any successor 
provision) under the Securities Act; (y) it shall have been sold or

agency thereto.

     "Securities Act" shall mean the Securities Act of 1933, as amended.

     2.  INCIDENTAL REGISTRATIONS.

     (a)  RIGHT TO INCLUDE REGISTRABLE SHARES.  On or after June 1, 1998 (the 
"Rights Commencement Date"), each time the Company shall determine to file a 
registration statement under the Securities Act in connection with a proposed 
offer and sale for cash of any equity securities (other than an offering of 
debt securities which are convertible into equity securities) by the Company, 
the Company will give prompt written notice of its determination to each 
Holder and of such Holder's rights under this Section 0, at least twenty (20) 
days prior to the anticipated filing date of such registration statement.  
Upon the written request of each Holder made within fifteen (15) days after 
the receipt of any such notice from the Company (which request shall specify 
the Registrable Shares intended to be disposed of by such Holder), the 
Company will use its best efforts to effect the registration under the 
Securities Act of all Registrable Shares which the Company has been so 
requested to register by the Holders thereof, to the extent required to 
permit the disposition of the Registrable Shares so to be registered; 
PROVIDED, HOWEVER, that (i) if, at any time after giving written notice of 
its intention to register any securities and prior to the effective date of 
the registration statement filed in connection with such registration, the 
Company shall determine for any reason not to proceed with the proposed 
registration of the securities to be sold by it, the Company may, at its 
election, give written notice of such determination to each Holder of 
Registrable Shares and thereupon shall be relieved of its obligation to 
register any Registrable Shares in connection with such registration (but not 
from its obligation to pay the Registration Expenses in connection 
therewith), and (ii) if such registration involves an underwritten offering, 
all Holders of Registrable Shares requesting to be included in the Company's 
registration must sell their Registrable Shares to the underwriters on the 
same terms and conditions as apply to the Company, with such differences, 
including any with respect to indemnification and liability insurance, as may 
be customary or appropriate in combined primary and secondary offerings.  If 
a registration requested pursuant to this Section 2(a) involves an 
underwritten public offering, any Holder of Registrable Shares requesting to 
be included in such registration may elect, in writing at least five (5) days 
prior to the effective date of the registration statement filed in connection 
with such registration, not to register such securities in connection with 
such registration.  No registration effected under this Section 0 shall 
relieve the Company of its obligations to effect the registration under 
Section 0 hereof.

     (b)  PRIORITY IN INCIDENTAL REGISTRATION.  If a registration pursuant to
this Section 0 involves an underwritten offering and the managing underwriter(s)
in good faith advise(s) the Company in writing that, in its opinion, the number
of securities which the Company, the Holders and any other Persons intend to
include in such registration exceeds the largest number of securities which can
be sold in such offering without having an adverse effect on such offering
(including the price at which such securities can be sold), then the Company
will include in such registration (i) first, the securities the Company proposes
to sell for its own 

                                      -3-
<PAGE>

account; (ii) second, to the extent that the number of securities which the 
Company proposes to sell is less than the number of securities which the 
Company has been advised can be sold in such offering without having the 
adverse effect referred to above, such number of Registrable Shares which the 
Holders have requested to be included in such registration pursuant to 
Section 2(a) hereof; PROVIDED, HOWEVER, that the aggregate value of the 
Registrable Securities to be included in such registration by the Holders may 
not be so reduced to less than twenty-five percent (25%) of the total value 
of all securities included in such registration; and (iii) third, to the 
extent that the number of securities which are to be included in such 
registration pursuant to clauses (i) and (ii) is, in the aggregate, less than 
the number of securities which the Company has been advised can be sold in 
such offering without having the adverse effect referred to above, such 
number of other securities requested to be included in the offering for the 
account of any Other Holders which, in the opinion of such managing 
underwriter(s), can be sold without having the adverse effect referred to 
above.  The number of Registrable Shares included in such registration 
statement shall be allocated pro rata among the Holders based on the number 
of Registrable Shares held by each Holder.

     3.  HOLDBACK AGREEMENTS.

     (a)  If any registration of Registrable Shares shall be in connection 
with a Qualified Public Offering (defined below), the Holders shall not 
effect any public sale or distribution (except in connection with such public 
offering), of any Registrable Securities (other than as part of such 
underwritten public offering) during the one hundred twenty (120) day period 
(or such lesser period as the managing underwriter(s) may permit) beginning 
on the effective date of such registration, if, and to the extent, the 
managing underwriter(s) of any such offering determine(s) such action is 
necessary or desirable to effect such offering.  A "Qualified Public 
Offering" is defined herein as a firm commitment, underwritten public 
offering registered under the Securities Act (other than a registration 
relating solely to a transaction under Rule 145 under the Securities Act or 
to an employee benefit plan of the Company), at a price per share of at least 
$2.00 and with aggregate proceeds to the Company and/or any selling 
shareholders (before deduction for underwriters' discounts and expenses) of 
at least $7,500,000.

     (b)  If any registration of Registrable Shares shall be in connection 
with a Qualified Public Offering, the Company shall not effect any public 
sale or distribution (except in connection with such public offering) of any 
of its equity securities or of any security convertible into or exchangeable 
or exercisable for any of its equity securities (in each case other than as 
part of such underwritten public offering) during the one hundred twenty 
(120) day period (or such lesser period as the managing underwriter(s) may 
permit) beginning on the effective date of such registration, and the Company 
shall use its best efforts to cause each member of the management of the 
Company who holds any equity security and each other holder of five percent 
(5%) or more of the outstanding shares of any equity security, or of any 
security convertible into or exchangeable or exercisable for any equity 
security, of the Company purchased from the Company (at any time other than 
in a public offering) to so agree.

     (c)  In the event of any discretionary waiver or termination of the 
restrictions set forth in the agreements described in Section 3(b) above by 
the Company or the representatives 

                                      -4-
<PAGE>

of the underwriters, the number of shares subject to such waiver shall be 
allocated among all persons subject to such agreements and to all Holders pro 
rata based on the number of securities held.

     4.  REGISTRATION.

     (a)  MANDATORY REGISTRATION.  The Company shall prepare and, no later 
than 305 days after the date of issuance of the Common Shares (the "Filing 
Deadline"), file with the SEC a registration statement on Form S-3 covering 
the resale of all of the Registrable Shares, or such lesser amount of 
Registrable Shares as the Holders shall in their discretion notify the 
Company to register. In the event that Form S-3 is unavailable for such a 
registration, the Company shall use such other form as is available for such 
a registration, subject to the further provisions of this Section 4(a).  The 
Company shall use its best efforts to have the registration statement 
declared effective no later than 365 days after the date of issuance of the 
Common Shares and in any event shall have the registration declared effective 
no later than 380 days after the date of issuance of the Common Shares.  In 
the event that Form S-3 is not available for the registration of Registrable 
Shares hereunder, the Company shall (i) register the sale of the Registrable 
Shares on another appropriate form and (ii) undertake to register the 
Registrable Shares on Form S-3 as soon as such form is available, provided 
that the Company shall maintain the effectiveness of the registration 
statement then in effect until such time as a registration statement on Form 
S-3 covering the Registrable Shares has been declared effective by the SEC.  
No securities other than Registrable Shares will be included in any 
registration statement filed pursuant to this Section 4(a) subject to Section 
4(e) below.  The Company shall keep a registration statement described in 
this Section 4(a) hereof effective pursuant to Rule 415 promulgated under the 
Securities Act at all times until the earlier of (i) the date as of which 
each of the Holders may sell all of the Registrable Shares held by such 
Holder without restriction pursuant to Rule 144(k) promulgated under the 
Securities Act or (ii) the date on which the Holders shall have sold all the 
Registrable Shares to the public (the"Registration Period").  The 
registration statement (including any amendments or supplements thereto and 
prospectuses contained therein) shall not contain any untrue statement of a 
material fact or omit to state a material fact required to be stated therein, 
or necessary to make the statements therein, in light of the circumstances in 
which they were made, not misleading.

     (b)  BLACK-OUT PERIODS.  If (i) in the good faith judgment of the Board 
of Directors of the Company, the disclosure which would be required in 
connection with the mandatory registration under Section 4(a) above would be 
seriously detrimental to the Company and the Board of Directors of the 
Company concludes by a duly adopted resolution that, as a result, it is 
essential at such time to defer the filing of such registration statement or 
to suspend the sale of securities thereunder, and (ii) the Company shall 
furnish to such Holders a certificate signed by the President of the Company 
stating that in the good faith judgment of the Board of Directors of the 
Company it would be seriously detrimental to the Company for such 
registration statement to be filed or for securities to be sold thereunder in 
the near future and that it is, therefore, essential to defer the filing of 
such registration statement or to suspend the sale of securities thereunder, 
then the Company shall have the right to defer such filing or suspend the 
sale of securities thereunder for the period during which such disclosure 
would be seriously 

                                      -5-

detrimental (a "Black-out Period"); PROVIDED, HOWEVER, that (A) the Company 
shall not have the right to impose any Black-out Periods for ninety (90) days 
following the effectiveness of the registration statement filed pursuant to 
Section 4(a) above, (B) no Black-out Period shall extend longer than 
forty-five (45) consecutive calendar days, (C) no Black-out Period may be 
imposed within forty-five (45) days following the completion of a prior 
Black-out Period, and (D) the Company shall not impose Black-out Periods 
which, in the aggregate, exceed ninety (90) days in any twelve (12) month 
period.  The Holders acknowledge and agree that the Company may impose a 
legend setting forth the provisions of this Section 4(b) on the Registrable 
Shares.

     (c)  SUBSEQUENT REGISTRATIONS.  In the event fewer than all of the 
Registrable Shares are covered by the registration effectuated pursuant to 
Section 4(a) above, then, commencing six (6) months following the effective 
date of such registration, upon the written request of the Holders of at 
least fifty percent (50%) of the Registrable Shares not so covered that the 
Company effect the registration of all or part of such Registrable Shares not 
so covered, and specifying the amount and the intended method of disposition 
thereof, the Company will promptly give notice of such requested registration 
to all other Holders of Registrable Shares not so covered and, as 
expeditiously as possible, use its best efforts to effect the registration 
under the Securities Act of: (i) the Registrable Shares which the Company has 
been so requested to register by such requesting Holders; and (ii) all other 
Registrable Shares which the Company has been requested to register by any 
other Holder thereof by written request received by the Company within thirty 
(30) days after the giving of such written notice by the Company; PROVIDED, 
HOWEVER, that the Company shall not be required to effect more than one (1) 
registration pursuant to this Section 4(c); PROVIDED, FURTHER, that the 
Company shall not be obligated to file a registration statement relating to a 
registration request under this Section 4(c), (x) if the registration request 
is delivered after delivery of a notice by the Company of an intended 
registration and prior to the effective date of the registration statement 
referred to in such notice, provided that the Company is actively employing 
in good faith all reasonable efforts to cause such registration statements to 
become effective, or (y) within a period of ninety (90) days after the 
effective date of any other registration statement of the Company pursuant to 
which the Holders included Registrable Shares.

     (d)  REGISTRATION STATEMENT FORM.  If any registration pursuant to this 
Section 0 shall be in connection with an underwritten public offering, and if 
the managing underwriter(s) shall advise the Company in writing that, in its 
opinion, the use of a form of registration statement other than on Form S-3 
is of material importance to the success of such proposed offering, then such 
registration shall be effected on such other form.

     (e)  PRIORITY IN REQUESTED REGISTRATIONS.  If any registration pursuant 
to this Section 0 involves an underwritten offering and the managing 
underwriter(s) in good faith advise(s) the Company in writing that, in its 
opinion, the number of securities requested to be included in such 
registration (including securities of the Company which are not Registrable 
Shares) exceeds the largest number of securities which can be sold in such 
offering without having an adverse effect on such offering (including the 
price at which such securities can be sold), then the Company will include in 
such registration (i) first, one hundred percent (100%) of the Registrable 
Shares requested to be registered pursuant to Section 4(a) hereof (provided 
that if 

                                      -6-
<PAGE>


the number of Registrable Shares requested to be registered pursuant to 
Section 4(a) hereof exceeds the number which the Company has been advised can 
be sold in such offering without having the adverse effect referred to above, 
the number of such Registrable Shares to be included in such registration by 
the Holders shall be allocated pro rata among such Holders on the basis of 
the relative number of Registrable Shares each such Holder has requested to 
be included in such registration); (ii) second, to the extent that the number 
of Registrable Shares requested to be registered pursuant to Section 4(a) 
hereof is less than the number of securities which the Company has been 
advised can be sold in such offering without having the adverse effect 
referred to above, such number of shares of equity securities the Company 
requests to be included in such registration, and (iii) third, to the extent 
that the number of Registrable Shares requested to be included in such 
registration pursuant to Section 4(a) hereof and the securities which the 
Company proposes to sell for its own account are, in the aggregate, less than 
the number of equity securities which the Company has been advised can be 
sold in such offering without having the adverse effect referred to above, 
such number of other securities proposed to be sold by any Other Holder 
which, in the opinion of such managing underwriter(s), can be sold without 
having the adverse effect referred to above (provided that if the number of 
such securities of such Other Holder requested to be registered exceeds the 
number which the Company has been advised can be sold in such offering 
without having the adverse effect referred to above, the number of such 
securities to be included in such registration pursuant to this Section 4(d) 
shall be allocated pro rata among all such Other Holders on the basis of the 
relative number of securities each such Other Holder has requested to be 
included in such registration).

     (f)  ADDITIONAL RIGHTS.  If the Company at any time grants to any other 
holders of equity securities of the Company any rights to request the Company 
to effect the registration of any such shares of equity securities on terms 
more favorable to such holders than the terms set forth in this Section 4 and 
in Section 5 hereof, the terms of this Section 4 and of Section 5 hereof 
shall be deemed amended or supplemented to the extent necessary to provide 
the Holders such more favorable rights and benefits.  In no event shall the 
Company grant to any person any rights to request the Company to effect the 
registration of any shares of equity securities of the Company on terms which 
would have the effect of delaying the effectiveness of or reducing the number 
of shares covered by any registration statements effectuated pursuant to 
Section 2 and this Section 4.

     5.  REGISTRATION PROCEDURES.

     (a)  Whenever a Holder has requested that any Registrable Shares be 
registered pursuant to Section 2(a) or 4(c) or at such time as the Company is 
obligated to file and maintain the effectiveness of a registration statement 
with the SEC pursuant to Section 4(a), the Company shall use its best efforts 
to effect the registration of the Registrable Shares in accordance with the 
intended method of disposition thereof and, pursuant thereto, the Company 
shall have the following obligations:

          (i)  prepare and file with the SEC such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as 

                                      -7-
<PAGE>


     may be necessary to keep such registration statement effective for 
     the Registration Period and to comply with the provisions of the 
     Securities Act, the Exchange Act, and the rules and regulations 
     promulgated thereunder with respect to the disposition of all the 
     securities covered by such registration statement during such 
     period in accordance with the intended methods of disposition by 
     the Holders thereof set forth in such registration statement; 
     PROVIDED, HOWEVER, that (A) before filing a registration statement 
     (including an initial filing) or prospectus, or any amendments or 
     supplements thereto, the Company will furnish to one counsel (the 
     "Holder Counsel") selected by the Holders of a majority of the 
     Registrable Shares covered by such registration statement copies 
     of all documents proposed to be filed at least seven days prior to 
     their filing with the SEC, which documents will be subject to the 
     review and comment of such counsel, and (B) the Company will 
     notify each Holder of Registrable Shares covered by such 
     registration statement of any stop order issued or threatened by 
     the SEC, any other order suspending the use of any preliminary 
     prospectus or of the suspension of the qualification of the 
     registration statement for offering or sale in any jurisdiction, 
     and take all reasonable actions required to prevent the entry of 
     such stop order, other order or suspension or to remove it if 
     entered;

          (ii)  the Company shall furnish to the Holder Counsel, without
     charge, any correspondence from the SEC or the staff of the SEC to the
     Company or its representatives relating to any registration statement;

          (iii)  furnish without charge to each Holder and each
     underwriter, if applicable, of Registrable Shares covered by such
     registration statement such number of copies of the registration
     statement and of each amendment and supplement thereto (in each case
     including all exhibits), such number of copies of the prospectus
     included in such registration statement (including each preliminary
     prospectus and summary prospectus), in conformity with the
     requirements of the Securities Act, and such other documents as each
     Holder of Registrable Shares covered by such registration statement
     may reasonably request in order to facilitate the disposition of the
     Registrable Shares by such Holder;

          (iv)  use its best efforts to register or qualify such
     Registrable Shares covered by such registration statement under the
     state securities or blue sky laws of such jurisdictions as each Holder
     of Registrable Shares covered by such registration statement and, if
     applicable, each underwriter, may reasonably request, and do any and
     all other acts and things which may be reasonably necessary to
     consummate the disposition in such jurisdictions of the Registrable
     Shares owned by such Holder, except that the Company shall not for any
     purpose be required to qualify generally to do business as a foreign
     corporation in any jurisdiction where, but for the requirements of
     this clause (iv), it would not be obligated to be so qualified (the
     Company shall promptly notify Holder 

                                      -8-

<PAGE>

     Counsel and each Holder of the receipt by the Company of any 
     notification with respect to the suspension of the registration or 
     qualification of any of the Registrable Shares for sale under the 
     securities or "blue sky" laws of any jurisdiction in the United 
     States or its receipt of actual notice of the initiation or 
     threatening of any proceeding for such purpose);

          (v)  use its best efforts to cause such Registrable Shares
     covered by such registration statement to be registered with or
     approved by such other governmental agencies or authorities as may be
     necessary to enable the Holders thereof to consummate the disposition
     of such Registrable Shares;

          (vi)  if at any time an event shall have occurred as the result
     of which any prospectus relating to any Registrable Shares as then in
     effect would include an untrue statement of a material fact or omit to
     state any material fact required to be stated therein or necessary to
     make the statements therein not misleading, immediately give written
     notice thereof to each Holder and the managing underwriter or
     underwriters, if any, of such Registrable Shares and prepare and
     furnish to each such Holder a reasonable number of copies of an
     amended or supplemental prospectus as may be necessary so that, as
     thereafter delivered to the purchasers of such Registrable Shares,
     such prospectus shall not include an untrue statement of material fact
     or omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading;

          (vii)  either (A) list any portion of such Registrable Shares not
     already listed on any securities exchange on which similar securities
     of the Company are then listed, and enter into customary agreements
     including a listing application and indemnification agreement in
     customary form, or (B) maintain the inclusion for quotation on The
     Nasdaq SmallCap Market for the Registrable Shares and, at such time as
     the Company is able to satisfy the listing requirements on the Nasdaq
     National Market System and the Company's management reasonably
     believes the Company will be able to continue to comply with such
     requirements, use its best efforts to secure designation and quotation
     of all the Registrable Shares on the Nasdaq National Market System,
     and, without limiting the generality of the foregoing, use its best
     efforts to arrange for at least two market makers to register with the
     NASD as such with respect to the Registrable Shares, and provide a
     transfer agent and registrar for such Registrable Shares covered by
     such registration statement not later than the effective date of such
     registration statement;

          (viii)  enter into such customary agreements (including an
     underwriting agreement in customary form) and take such other actions
     as each Holder of Registrable Shares being sold or the underwriter or
     underwriters, if any, reasonably request in order to expedite or
     facilitate the disposition of such Registrable Shares, including
     customary indemnification and opinions;

                                      -9-

<PAGE>

          (ix)  use its best efforts to obtain a "cold comfort" letter or
     letters from the Company's independent public accountants in customary
     form and covering matters of the type customarily covered by "cold
     comfort" letters as the Holders of the Registrable Shares being sold
     or the underwriters retained by such Holders shall reasonably request,
     provided that this provision shall only apply with respect to an
     underwritten registration;

          (x)  make available for inspection by representatives of any
     Holder, by any underwriter participating in any disposition to be
     effected pursuant to such registration statement and by any attorney,
     accountant or other agent retained by such Holders or any such
     underwriter, all financial and other records pertinent corporate
     documents and properties of the Company and its subsidiaries'
     officers, directors and employees to supply all information and
     respond to all inquiries reasonably requested by such Holders or any
     such representative, underwriter, attorney, accountant or agent in
     connection with such registration statement;

          (xi)  promptly prior to the filing of any document which is to be
     incorporated by reference into the registration statement or the
     prospectus (after initial filing of the registration statement), if
     such document is not available to the public electronically via EDGAR,
     provide copies of such document to counsel to the Holders and to the
     managing underwriter(s), if any, and make the Company's
     representatives available for discussion of such document;

          (xii)  otherwise use its best efforts to comply with all
     applicable rules and regulations of the SEC, and make available to its
     security holders, as soon as reasonably practicable after the
     effective date of the registration statement, an earning statement
     which shall satisfy the provisions of section 11(a) of the Securities
     Act and the rules and regulations promulgated thereunder;

          (xiii)  not later than the effective date of the applicable
     registration statement, use its best efforts to provide a CUSIP number
     for any portion of such Registrable Shares not already included in a
     CUSIP number for similar securities of the Company, and provide the
     applicable transfer agents with printed certificates for the
     Registrable Shares which are in a form eligible for deposit with the
     Depository Trust Company;

          (xiv)  notify counsel for the Holders of Registrable Shares
     included in such registration statement and the managing underwriter
     or underwriters, if any, immediately and confirm the notice in
     writing, (A) when the registration statement, or any post-effective
     amendment to the registration statement, shall have become effective,
     or any supplement or amendment to the prospectus shall have been
     filed, (B) of the receipt of any comments from the SEC and (C) of any
     request of the SEC to amend the registration statement or amend or
     supplement the prospectus or for additional information;

                                      -10-
<PAGE>


          (xv)  in the event the Company and the Holders who hold at least
     two-thirds of the Registrable Shares mutually agree to an underwritten
     offering for one or more offerings of Registrable Shares under Section
     4(a) hereof, enter into and perform its obligations under an
     underwriting agreement, in usual and customary form, including, but
     not limited to, customary indemnification and contribution
     obligations, with the underwriters (without limiting the generality of
     the foregoing, if the underwriters for marketing or other reasons
     request the inclusion in the registration statement of information
     which is not required under the Securities Act to be included in a
     registration statement on the applicable form for such registration,
     the Company nonetheless will provide such information as may be
     reasonably requested for inclusion by the underwriters in such
     registration statement);

          (xvi)  use its best efforts to prevent the issuance of any stop
     order or other suspension of effectiveness of a registration
     statement, or the suspension of the qualification of any of the
     Registrable Shares for sale in any jurisdiction and, if such an order
     or suspension is used, use its best efforts to obtain the withdrawal
     of such order or suspension at the earliest possible time;

          (xvii)  cooperate with each of the Holders and, to the extent
     applicable, any managing underwriter or underwriters, to facilitate
     the timely preparation and delivery of certificates (not bearing any
     restrictive legend) representing the Registrable Shares offered and
     sold pursuant to a registration statement and enable such certificates
     to be in such denominations or amounts, as the case may be, as the
     managing underwriter or underwriters, if any, or, if there is no
     managing underwriter or underwriters, each of the Holders may
     reasonably request and registered in such names as the managing
     underwriter or underwriters, if any, or each of the Holders may
     request;

          (xviii)  cooperate with each seller of Registrable Shares and
     each underwriter, if any, participating in the disposition of such
     Registrable Shares and their respective counsel in connection with any
     filings required to be made with the NASD; and

          (xix)  take all other reasonable actions necessary or reasonably
     requested by an Holder to expedite and facilitate disposition by such
     Holder of Registrable Shares pursuant to a registration statement.

     (b)  Each Holder of Registrable Shares hereby agrees that, upon receipt 
of any notice from the Company of the happening of any event of the type 
described in Section 5(a)(vi) hereof, such Holder shall forthwith discontinue 
disposition of such Registrable Shares covered by such registration statement 
or related prospectus until such Holder's receipt of the copies of the 
supplemental or amended prospectus contemplated by Section 5(a)(vi) hereof, 
and, if so directed by the Company, such Holder will deliver to the Company 
(at the Company's 

                                     -11-
<PAGE>

expense) all copies, other than permanent file copies then in such Holder's 
possession, of the prospectus covering such Registrable Shares at the time of 
receipt of such notice.

     (c)  Each Holder hereby agrees to provide the Company, upon receipt of 
its request, with such information about such Holder to enable the Company to 
comply with the requirements of the Securities Act and to execute such 
certificates as the Company may reasonably request in connection with such 
information and otherwise to satisfy any requirements of law.

     6.  UNDERWRITTEN REGISTRATIONS.  Notwithstanding anything in this 
Agreement to the contrary, the Company in its sole discretion shall determine 
whether a registration on Form S-3 pursuant to Section 4 hereof shall be by 
means of an underwritten offering.  In the case of any underwritten offerings 
pursuant to Section 2 and Section 4 hereof, the managing underwriter(s) that 
will administer the offering shall be selected by the Company; PROVIDED, 
HOWEVER, that such managing underwriter(s) shall be reasonably satisfactory 
to the Holders of a majority of the Registrable Shares to be registered.  

     7.  EXPENSES.

     (a)  Subject to Section 7(b), the Company shall pay all fees, costs and 
expenses of all registrations pursuant to Section 2 and Section 0 hereof, 
including all SEC and stock exchange or NASD registration and filing fees and 
expenses, reasonable fees and expenses of any "qualified independent 
underwriter" and its counsel as may be required by the rules of the NASD,

for Registrable Shares and prospectuses), messenger, telephone and delivery 
expenses, the fees and expenses incurred in connection with the listing of 
the securities to be registered on each securities exchange or national or 
other market system on which similar securities issued by the Company are 
then listed, fees and disbursements of counsel for the Company and all 
independent certified public accountants (including the expenses of any 
annual audit, special audit and "cold comfort" letters required by or 
incident to such performance and compliance), the fees and disbursements of 
the underwriters customarily paid by issuers or sellers of securities 
(including expenses relating to "road shows" and other marketing activities), 
the reasonable fees and expenses of special experts required to be retained 
by the Company in connection with such registration, the reasonable fees and 
expenses of other Persons required to be retained by the Company and the 
reasonable fees and expenses, not to exceed $10,000 per registration 
statement, of one counsel for the Holders (collectively, "Registration 
Expenses");

     (b)  The Holders shall pay the following:  (i) any underwriting or 
selling discounts or commissions or transfer taxes, if any, attributable to 
the sale of Registrable Shares by the Holders pursuant to this Agreement, and

     8.  INDEMNIFICATION.

     (a)  INDEMNIFICATION BY THE COMPANY.  In the event of any registration 
of any securities of the Company under the Securities Act pursuant to Section 
2 or 4 hereof, the Company will, and it hereby does, indemnify and hold 
harmless, to the fullest extent permitted by law, each of the Holders of any 
Registrable Shares covered by such registration statement, each Affiliate of 
such Holder (other than the Company) and their respective partners, members, 
Affiliates, directors and officers, each other Person who participates as an 
underwriter in the offering or sale of such securities and each other Person, 
if any, who controls such Holder or any such underwriter within the meaning 
of the Securities Act (collectively, the "Indemnified Parties"), against any 
and all losses, claims, damages or liabilities, joint or several, and 
expenses (including any amounts paid in any settlement effected with the 
Company's consent, which consent shall not be unreasonably withheld or 
delayed) to which any Indemnified Party may become subject under the 
Securities Act, state securities or blue sky laws, common law or otherwise, 
insofar as such losses, claims, damages or liabilities (or actions or 
proceedings in respect thereof, whether or not such Indemnified Party is a 
party thereto) or expenses arise out of or are based upon any of the 
following (each, a "Violation") (i) any untrue statement or alleged untrue 
statement of any material fact contained in any registration statement under 
which such securities were registered under the Securities Act, any 
preliminary, final or summary prospectus contained therein, or any amendment 
or supplement thereof, (ii) any omission or alleged omission to state therein 
a material fact required to be stated therein or necessary to make the 
statements therein not misleading or (iii) any violation by the Company of 
any federal, state or common law rule or regulation applicable to the Company 
and relating to action required of or inaction by the Company in connection 
with any such registration, and the Company will promptly reimburse such 
Indemnified Party for any legal or any other expenses reasonably incurred by 
it in connection with investigating or defending any such loss, claim, 
liability, action or proceeding; PROVIDED, HOWEVER, that the Company shall 
not be liable to any Indemnified Party in any such case to the extent that 
any such loss, claim, damage, liability (or action or proceeding in respect 
thereof) or expense arises out of or is based upon any untrue statement or 
alleged untrue statement or omission or alleged omission made in such 
registration statement or amendment or supplement thereof or in any such 
preliminary, final or summary prospectus in reliance upon and in conformity 
with written information with respect to such Holder furnished to the Company 
by such Holder specifically for use in the preparation thereof.  Such 
indemnity shall remain in full force and effect regardless of any 
investigation made by or on behalf of such Holder or any Indemnified Party 
and shall survive the transfer of such securities by such Holder.

     (b)  INDEMNIFICATION BY THE HOLDERS AND THE UNDERWRITERS.  In the event 
of any registration of any securities of the Company under the Securities Act 
pursuant to Section 2 or 4 hereof, each Holder of Registerable Shares 
included in the Securities as to which such registration is being effected 
will, and it hereby does, indemnify and hold harmless, to the fullest extent 
permitted by law, the Company, each Affiliate of the Company, each of its 
directors, each of its officers who has signed the registration statement, 
each Person, if any, who controls the Company within the meaning of the 
Securities Act, any underwriter, any other 

                                      -13-
<PAGE>

Holder selling securities under such registration statement and any 
controlling person of any such underwriter or other Holder (collectively, the 
"Company Indemnified Parties"), against any and all losses, claims, damages 
or liabilities, joint or several, and expenses (including amounts paid in any 
settlement effected with the Holder's prior written consent, which consent 
shall not be unreasonably withheld or delayed) to which any Company 
Indemnified Party may become subject under the Securities Act, state 
securities or blue sky laws, common law or otherwise, insofar as such losses, 
claims, damages or liabilities (or actions or proceedings in respect thereof, 
whether or not such Company Indemnified Party is a party thereto) or expenses 
arise out of or are based upon any Violation, in each case to the extent (and 
only to the extent) that such Violation occurs due to the Company's reliance 
upon and in conformity with written information furnished by such Holder to 
the Company under an instrument duly executed by such Holder and stated to be 
specifically for use in connection with such registration statement, 
preliminary, final or summary prospectus or amendment or supplement thereto; 
and each such Holder will promptly reimburse such Company Indemnified Party 
for any legal or any other expenses reasonably incurred by it in connection 
with investigation or defending any such loss, claim, liability, action or 
proceeding if it is judicially determined that there was such a Violation; 
PROVIDED, HOWEVER, that each such Holder shall be severally, and not jointly, 
liable under any such indemnification; PROVIDED, FURTHER, that no such Holder 
shall be liable in any event for any indemnity claims in excess of the amount 
of the net proceeds received by such Holder from the sale of its Registrable 
Shares.  The Company may further require, in connection with any underwritten 
registration effectuated in accordance with Section 2 or 4 hereof, that the 
Company shall have received an undertaking reasonably satisfactory to it from 
the underwriter to indemnify and hold harmless (in the same manner and to the 
same extent as set forth in this Section 8(b)) the Company with respect to 
any statement or alleged statement in or omission or alleged omission from 
such registration statement, any preliminary, final or summary prospectus 
contained therein, or any amendment or supplement, if such statement or 
alleged statement or omission or alleged omission was made in reliance upon 
and in conformity with written information such underwriter furnished to the 
Company specifically for use in the preparation of such registration 
statement, preliminary, final or summary prospectus or amendment or 
supplement.  Such indemnity shall remain in full force and effect regardless 
of any investigation made by or on behalf of the Company or any of the 
Holders, or any of their respective Affiliates (other than the Company), 
directors, officers or controlling Persons, and shall survive the transfer of 
such securities by such Holder.

     (c)  NOTICES OF CLAIMS, ETC.  Promptly after receipt by an indemnified
party hereunder of written notice of the commencement of any action or
proceeding with respect to which a claim for indemnification may be made
pursuant to this Section 8, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party, give written notice to the
latter of the commencement of such action; PROVIDED, HOWEVER, that the failure
of the indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under this Section 8, except to the extent
that the indemnifying party is actually materially prejudiced by such failure to
give notice.  In case any such action is brought against an indemnified party,
the indemnifying party will be entitled to participate in and to assume the
defense thereof, with counsel satisfactory to such indemnified party, and after
notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof, 

                                      -14-
<PAGE>

the indemnifying party will not be liable to such indemnified party for any 
legal or other expenses subsequently incurred by the latter in connection 
with the defense thereof other than reasonable costs of investigation; 
PROVIDED, HOWEVER, that the indemnified party shall have the right, at the 
sole cost and expense of the indemnifying party, to employ counsel to 
represent the indemnified party and its respective controlling persons, 
directors, officers, employees or agents who may be subject to liability 
arising out of any claim in respect of which indemnity may be sought by the 
indemnified party against such indemnifying party under this Section 8 if (i) 
the employment of such counsel shall have been authorized in writing by such 
indemnifying party in connection with the defense of such action, (ii) the 
indemnifying party shall not have promptly employed counsel reasonably 
satisfactory to the indemnified party to assume the defense of such action or 
counsel, or (iii) any indemnified party shall have reasonably concluded that 
there may be defenses available to such indemnified party or its respective 
controlling persons, directors, officers, employees or agents which are in 
conflict with or in addition to those available to an indemnifying party; 
PROVIDED, FURTHER, that the indemnifying party shall not be obligated to pay 
for more than the expenses of one firm of separate counsel for the 
indemnified party.  No indemnifying party will consent to entry of any 
judgment or enter into any settlement which does not include as an 
unconditional term thereof the giving by the claimant or plaintiff to such 
indemnified party of a release from all liability in respect to such claim or 
litigation.

     (d)  If the indemnification provided for in this Section 8 shall for any 
reason be unavailable to any indemnified party under Section 8(a) or 8(b) 
hereof or is insufficient to hold it harmless in respect of any loss, claim, 
damage or liability, or any action in respect of any loss, claim, damage or 
liability, or any action in respect thereof referred to therein, then each 
indemnifying party shall contribute to the amount paid or payable by such 
indemnified party as a result of such loss, claim, damage or liability, or 
action in respect thereof, (i) in such proportion as shall be appropriate to 
reflect the relative benefits received by the indemnified party and 
indemnifying party or (ii) if the allocation provided by clause (i) above is 
not permitted by applicable law, in such proportion as is appropriate to 
reflect not only the relative benefits referred to in clause (i) but also the 
relative fault of the indemnified party and indemnifying party with respect 
to the statements or omissions which resulted in such loss, claim, damage or 
liability, or action in respect thereof, as well as any other relevant 
equitable considerations.  Notwithstanding any other provision of this 
Section 8(d), no Holder of Registrable Shares shall be required to contribute 
an amount greater than the dollar amount of the net proceeds received by such 
Holder with respect to the sale of any such Registrable Shares.  No person 
guilty of fraudulent misrepresentation (within the meaning of section 11(f) 
of the Securities Act) shall be entitled to contribution from any person who 
was not guilty of such fraudulent misrepresentation.

     (e)  OTHER INDEMNIFICATION.  Indemnification similar to that specified 
in the preceding subdivisions of this Section 8 (with appropriate 
modifications but subject to the same provisos set forth in Section 8(b) 
above) shall be given by the Company and each Holder of Registrable Shares 
with respect to any required registration or other qualification of 
securities under any federal or state law or regulation other than the 
Securities Act.

                                      -15-
<PAGE>

     (f)  NON-EXCLUSIVITY.  The obligations of the parties under this Section 
8 shall be in addition to any liability which any party may otherwise have to 
any other party.

     9.  RULE 144. With a view to making available to the Holders the 
benefits of Rule 144 promulgated under the Securities Act or any other 
similar rule or regulation of the SEC that may at any time permit the Holders 
to sell securities of the Company to the public without registration ("Rule 
144"), the Company agrees to:

          (a)  make and keep public information available, as those terms
     are understood and defined in Rule 144;

          (b)  file with the SEC in a timely manner all reports and other
     documents required of the Company under the Exchange Act, so long as
     the Company remains subject to such requirements and the filing of
     such reports and other documents is required for the applicable
     provisions of Rule 144; and

          (c)  furnish to each Holder so long as such Holder owns
     Registrable Shares, promptly upon request, (i) a written statement by
     the company that it has complied with the reporting requirements of
     Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the
     most recent annual or quarterly report of the Company and such other
     reports and documents so filed by the company, and (iii) such other
     information as may be reasonably requested to permit the Holders to
     sell such securities pursuant to Rule 144 without registration.

     10.  ASSIGNABILITY.  This Agreement shall be binding upon and shall 
inure to the benefit of the parties hereto and the Holders and their 
respective successors and permitted assigns.  Except as provided herein, no 
party may assign any of its rights or delegate any of its duties under this 
Agreement without the express consent of the other parties hereto.  In 
addition, and whether or not any express assignment shall have been made, the 
provisions of this Agreement which are for the benefit of the Holders shall 
also be for the benefit of and enforceable by any subsequent Holder, subject 
to the provisions contained herein.  Any Holder may assign any of its rights 
or delegate any of its duties under this Agreement, in whole or in part, 
without any prior consent of the Company only to a Person (a "Designated 
Transferee") who is (a) an Affiliate, member or partner of a Holder, (b) a 
family member of or a trust for the benefit of an individual Holder, or (c) a 
transferee of at least 250,000 Registrable Shares (whether through purchase, 
share exchange, bequest or otherwise) and who agrees to be bound by the terms 
of this Agreement.  Any purported assignment in violation of this Section 10 
shall be void.

     11.  RIGHT OF FIRST REFUSAL.  The Company hereby grants to each Holder 
the right of first refusal to purchase a pro rata share of New Securities (as 
defined in this Section 12) which the Company may, from time to time, propose 
to sell and issue.  A Holder's pro rata share, for purposes of this right of 
first refusal, is the ratio of the number of shares of Common Stock owned by 
such Holder immediately prior to the issuance of New Securities, to the total 
number of shares of Common Stock outstanding immediately prior to the 
issuance of New Securities.  Each Holder shall have a right of over-allotment 
such that if any Holder fails to exercise its 

                                      -16-

<PAGE>

right hereunder to purchase its pro rata share of New Securities, the Company 
shall provide each Holder with prompt written notice of this event and the 
other Holders may purchase the non-purchasing Holder's portion on a pro rata 
basis within ten (10) days from the date of such notice. This right of first 
refusal shall be subject to the following provisions:

     (a)  "New Securities" shall mean any capital stock (including Common 
Stock and/or Preferred Stock) of the Company whether now authorized or not, 
and rights, options or warrants to purchase such capital stock, and 
securities of any type whatsoever that are, or may become, convertible into 
capital stock; provided that the term "New Securities" does not include (i) 
securities issued upon conversion of the warrants issued to CA on the date 
hereof; (ii) securities issued to investors and securities issuable upon 
exercise of the warrants issued to such investors in a private placement of 
the Company's Common Stock in an aggregate offering amount of up to $2.5 
million that will close as of the date hereof, (iii) securities issued 
pursuant to the acquisition of another business entity or business segment of 
any such entity by the Company by merger, purchase of substantially all the 
assets or other reorganization whereby the Company will own more than fifty 
percent (50%) of the voting power of such business entity or business segment 
of any such entity; (iv) any borrowings, direct or indirect, from financial 
institutions or other persons by the Company, whether or not presently 
authorized, including any type of loan or payment evidenced by any type of 
debt instrument, provided such borrowings do not have any equity features 
including warrants, options or other rights to purchase capital stock and are 
not convertible into capital stock of the Company; (v) securities issued to 
employees, consultants, officers or directors of the Company pursuant to any 
stock option, stock purchase or stock bonus plan, agreement or arrangement 
existing on the date hereof or hereafter approved by the unanimous vote of 
the Board of Directors or Compensation Committee; (vi) securities issued in 
connection with obtaining bona fide lease financing, whether issued to a 
lessor or guarantor; (vii) securities issued in a public offering of Common 
Stock of the Company pursuant to a firm-commitment underwritten registration 
under the Securities Act with an aggregate offering price to the public of at 
least $10,000,000 and in which no single purchaser or group of affiliated 
purchasers acquire in such offering greater than ten percent (10%) of the 
shares sold in the offering or three (3%) of then outstanding equity 
securities of the Company; and (viii) securities issued in connection with 
any stock split, stock dividend or recapitalization of the Company.

     (b)  In the event the Company proposes to undertake an issuance of New 
Securities, it shall give each Holder written notice of its intention, 
describing the type of New Securities, and their price and the general terms 
upon which the Company proposes to issue the same.  Each Holder shall have 
fifteen (15) days after any such notice is mailed or delivered to agree to 
purchase up to such Holder's pro rata share of such New Securities for the 
price and upon the terms specified in the notice by giving written notice to 
the Company and stating therein the quantity of New Securities to be 
purchased.

     (c)  In the event the Holders fail to exercise fully the right of first 
refusal within such fifteen (15) day period and after the expiration of the 
ten-day (10) period for the exercise of the over-allotment provisions of this 
Section 12, the Company shall have sixty (60) days thereafter to sell or 
enter into an agreement (pursuant to which the sale of New Securities covered 
thereby 

                                      -17-
<PAGE>

shall be closed, if at all, within ninety (90) days to sell the New 
Securities respecting which the Holders' right of first refusal option set 
forth in this Section 12 was not exercised, at a price and upon terms no more 
favorable to the purchasers thereof than specified in the Company's notice to 
Holders pursuant to Section 12(b).  In the event the Company has not sold 
within such 90-day period or entered into an agreement to sell the New 
Securities in accordance with the foregoing within sixty (60) days from the 
date of such agreement, the Company shall not thereafter issue or sell any 
New Securities, without first again offering such securities to the Holders 
in the manner provided in Section 12(b) above.

     (d)  The right of first refusal granted under this Agreement shall 
expire on the earlier to occur of (i) two (2) years from the date of this 
Agreement or (ii) the date the Holders as a group hold less than 15% of the 
issued and outstanding capital stock of the Company.

     12.  NOTICES.  Any and all notices, designations, consents, offers, 
acceptances or any other communications shall be given in writing by either 
(a) personal delivery to and receipted for by the addressee or by (b) 
telecopy or registered or certified mail which shall be addressed, in the 
case of the Company, to:  Centura Software Corporation, 975 Island Drive, 
Redwood Shores, California 94065, attention:  Chief Financial Officer; in the 
case of Holders, to the address or addresses thereof appearing on the books 
of the Company or of the transfer agent and registrar for its Common Stock.  
All such notices and communications shall be deemed to have been duly given 
and effective: when delivered by hand, if personally delivered; two (2) 
business days after being deposited in the mail, postage prepaid, if mailed; 
and when receipt is acknowledged, if telecopied.

     13.  NO INCONSISTENT AGREEMENTS.  The Company will not hereafter enter 
into any agreement with respect to its securities which is inconsistent with 
the rights granted to the Holders in this Agreement.

     14.  SPECIFIC PERFORMANCE.  The Company acknowledges that the rights 
granted to the Holders in this Agreement are of a special, unique and 
extraordinary character, and that any breach of this Agreement by the Company 
could not be compensated for by damages.  Accordingly, if the Company 
breaches its obligations under this Agreement, the Holders shall be entitled, 
in addition to any other remedies that they may have, to enforcement of this 
Agreement by a decree of specific performance requiring the Company to 
fulfill its obligations under this Agreement.

     15.  SEVERABILITY.  If any provision of this Agreement or any portion 
thereof is finally determined by a court of competent jurisdiction to be 
unlawful or unenforceable, such provision or portion thereof shall in no way 
affect any other provision of this Agreement, the application of any such 
provision and any other circumstances, and any portion of such invalidated 
provision that is not invalidated by such a determination shall remain in 
full force and effect.

     16.  COUNTERPARTS.  This Agreement may be executed in one or more 
counterparts, each of which shall be deemed an original and all of which, 
together, shall constitute one and the same instrument.

                                      -18-

     17.  DEFAULTS.  A default by any party to this Agreement in such party's 
compliance with any of the conditions or covenants hereof or performance of 
any of the obligations of such party hereunder shall not constitute a default 
by any other party.

     18.  AMENDMENTS, WAIVERS.  This Agreement may not be amended, modified 
or supplemented and no waivers of or consents to or departures from the 
provisions hereof may be given unless consented to in writing by the Company 
and the holders of two-thirds of the Registrable Shares; PROVIDED, HOWEVER, 
that no such amendment, supplement, modification or waiver shall deprive any 
Holder of any rights under Section 2 or 4 hereof without the consent of such 
Holder.

     19.  CONSTRUCTION.  The captions contained in this Agreement are for 
reference purposes only and shall not constitute a part of this Agreement. 
Unless the context requires otherwise, the use of the masculine shall include 
the feminine, and the use of the singular shall include the plural.  The word

asserted as a defense, the successful party shall be entitled to recover 
reasonable attorneys' fees in addition to any other available remedy.

     21.  ADDITIONAL ACTIONS.  Each party (including transferees and assigns 
thereof) shall do and perform, or cause to be done and performed, all such

Warrant No. CS98-21                                   Number of Shares: 283,019
Date of Issuance: February 27, 1998                     (subject to adjustment)

                         CENTURA SOFTWARE CORPORATION

                         COMMON STOCK PURCHASE WARRANT
                         -----------------------------

     Centura Software Corporation (the "COMPANY"), for value received, hereby 
certifies that Rochon Capital Group, Ltd., or its registered assigns (the 
"REGISTERED HOLDER"), is entitled, subject to the terms set forth below, to 
purchase from the Company, at any time after the date hereof and on or before 
the Expiration Date (as defined in Section 5 below), up to 283,019 shares (as 
adjusted from time to time pursuant to the provisions of this Warrant) of 
Common Stock of the Company, at a purchase price of $2.12 per share.  The 
shares purchasable upon exercise of this Warrant and the purchase price per 
share, as adjusted from time to time pursuant to the provisions of this 
Warrant, are sometimes hereinafter referred to as the "WARRANT STOCK" and the 
"PURCHASE PRICE," respectively.

    1. EXERCISE.

       (a) MANNER OF EXERCISE.  This Warrant may be exercised by the 
Registered Holder, in whole or in part, by surrendering this Warrant, with 
the purchase form appended hereto as EXHIBIT A duly executed by such 
Registered Holder or by such Registered Holder's duly authorized attorney, at 
the principal office of the Company, or at such other office or agency as the 
Company may designate, accompanied by payment in full of the Purchase Price 
payable in respect of the number of shares of Warrant Stock purchased upon 
such exercise.  The Purchase Price may be paid by cash, check or wire 
transfer to the Registered Holder.  

       (b) EFFECTIVE TIME OF EXERCISE.  Each exercise of this Warrant shall 
be deemed to have been effected immediately prior to the close of business on 
the day on which this Warrant shall have been surrendered to the Company as 
provided in Section 1(a) above.  At such time, the person or persons in whose 
name or names any certificates for Warrant Stock shall be issuable upon such 
exercise as provided in Section 1(d) below shall be deemed to have become the 
holder or holders of record of the Warrant Stock represented by such 
certificates.

       (c) NET ISSUE EXERCISE.

            (i) In lieu of exercising this Warrant in the manner provided 
above in Section 1(a), the Registered Holder may elect to receive shares equal 
to the value of this Warrant (or the portion thereof being canceled) by 
surrender of this Warrant at the principal office of the


<PAGE>

Company together with notice of such election in which event the Company 
shall issue to holder a number of shares of Common Stock computed using the 
following formula:

                            X = Y (A - B)
                                ---------
                                    A

Where  X = The number of shares of Common Stock to be issued to the 
           Registered Holder.

       Y = The number of shares of Common Stock as to which the Warrant is 
           being exercised

       A = The fair market value of one share of Common Stock (at the date of 
           such calculation).

       B = The Purchase Price (as adjusted to the date of such calculation).

           (ii) For purposes of this Section 1(c), the fair market value of 
one share of Common Stock on the date of calculation shall mean:

                (1) if the Company's Common Stock is traded on a securities 
exchange, The Nasdaq Stock Market, or The Nasdaq SmallCap Market, the fair 
market value shall be deemed to be the closing price on the trading day 
immediately preceding the date of exercise of the Warrant; or

                (2) if the Company's Common Stock is actively traded 
over-the-counter, the fair market value shall be deemed to be the closing bid 
or sales price (whichever is applicable) on the trading day immediately 
preceding the date of exercise of the Warrant; or

                (3) if neither (1) nor (2) is applicable, the fair market 
value shall be at the highest price per share which the Company could obtain 
on the date of calculation from a willing buyer (not a current employee or 
director) for shares of Common Stock sold by the Company, from authorized but 
unissued shares, as determined in good faith by the Board of Directors, 
unless the Company is at such time subject to an acquisition as described in 
Section 5(b) below, in which case the fair market value per share of Common 
Stock shall be deemed to be the value of the consideration per share received 
by the holders of such stock pursuant to such acquisition.

       (d) DELIVERY TO HOLDER.  As soon as practicable after the exercise of 
this Warrant in whole or in part, and in any event within three (3) days 
thereafter, the Company at its expense will cause to be issued in the name 
of, and delivered to, the Registered Holder, or as such Holder (upon payment 
by such Holder of any applicable transfer taxes) may direct:

            (i) a certificate or certificates for the number of shares of 
Warrant Stock to which such Registered Holder shall be entitled, and 

<PAGE>

           (ii) in case such exercise is in part only, a new warrant or 
warrants (dated the date hereof) of like tenor, calling in the aggregate on 
the face or faces thereof for the number of shares of Warrant Stock equal 
(without giving effect to any adjustment therein) to the number of such 
shares called for on the face of this Warrant minus the number of such 
shares purchased by the Registered Holder upon such exercise as provided in 
Section 1(a) above.

     2. ADJUSTMENTS.

        (a) STOCK SPLITS AND DIVIDENDS.  If outstanding shares of the 
Company's Common Stock shall be subdivided into a greater number of shares or 
a dividend in Common Stock shall be paid in respect of Common Stock, the 
Purchase Price in effect immediately prior to such subdivision or at the 
record date of such dividend shall simultaneously with the effectiveness of 
such subdivision or immediately after the record date of such dividend be 
proportionately reduced.  If outstanding shares of Common Stock shall be 
combined into a smaller number of shares, the Purchase Price in effect 
immediately prior to such combination shall, simultaneously with the 
effectiveness of such combination, be proportionately increased.  When any 
adjustment is required to be made in the Purchase Price, the number of shares 
of Warrant Stock purchasable upon the exercise of this Warrant shall be 
changed to the number determined by dividing (i) an amount equal to the 
number of shares issuable upon the exercise of this Warrant immediately prior 
to such adjustment, multiplied by the Purchase Price in effect immediately 
prior to such adjustment, by (ii) the Purchase Price in effect immediately 
after such adjustment.

        (b) RECLASSIFICATION, ETC.  In case of any reclassification or change 
of the outstanding securities of the Company or of any reorganization of the 
Company (or any other corporation the stock or securities of which are at the 
time receivable upon the exercise of this Warrant) or any similar corporate 
reorganization or merger or conveyance on or after the date hereof, then and 
in each such case the holder of this Warrant, upon the exercise hereof at any 
time after the consummation of such reclassification, change, reorganization, 
merger or conveyance, shall be entitled to receive, in lieu of the stock or 
other securities and property receivable upon the exercise hereof prior to 
such consummation, the stock or other securities or property to which such 
holder would have been entitled upon such consummation if such holder had 
exercised this Warrant immediately prior thereto, all subject to further 
adjustment as provided in Section 2(a); and in each such case, the terms of 
this Section 2 shall be applicable to the shares of stock or other securities 
properly receiv-able upon the exercise of this Warrant after such 
consummation.

       (c) ADJUSTMENT CERTIFICATE.  When any adjustment is required to be 
made in the Purchase Price, the Company shall promptly mail to the Registered 
Holder a certificate setting forth the Purchase Price after such adjustment 
and setting forth a brief statement of the facts requiring such adjustment.  
Such certificate shall also set forth the kind and amount of stock or other 
securities or property into which this Warrant shall be exercisable following 
the occurrence of any of the events specified in Section 2(a) or 2(b) above.

     3. TRANSFERS.  

        (a) UNREGISTERED SECURITY.  Each holder of this Warrant acknowledges 
that this Warrant and the Warrant Stock have not been registered under the 
Securities Act, and agrees not to sell, pledge, distribute, offer for sale, 
transfer or otherwise dispose of this Warrant or any Warrant

<PAGE>

Stock issued upon its exercise in the absence of (i) an effective 
registration statement under the Act as to this Warrant or such Warrant Stock 
and registration or qualification of this Warrant or such Warrant Stock under 
any applicable U.S. federal or state securities law then in effect or (ii) an 
opinion of counsel, satisfactory to the Company, that such registration and 
qualification are not required.  Each certificate or other instrument for 
Warrant Stock issued upon the exercise of this Warrant shall bear a legend 
substantially to the foregoing effect until such time as the registration of 
the Warrant Stock is effective or until such time as the Warrant Stock has 
been held by the holder (after giving effect to permissible tacking under 
Rule 144) for at least two years, at and after which time no legend shall be 
required.

        (b) TRANSFERABILITY.  Subject to the provisions of Section 3(a) 
hereof, this Warrant and all rights hereunder are transferable, in whole or 
in part, upon surrender of the Warrant with a properly executed assignment 
(in the form of EXHIBIT B hereto) at the principal office of the Company, 
PROVIDED, HOWEVER, that this Warrant may not be transferred in part unless 
the transferee and any subsequent tranferee acquires the right to purchase at 
least 25,000 shares (as adjusted pursuant to Section 2) of Warrant Stock 
hereunder.

        (c) WARRANT REGISTER.   The Company will maintain a register 
containing the names and addresses of the Registered Holders of this Warrant. 
 Until any transfer of this Warrant is made in the warrant register, the 
Company may treat the Registered Holder of this Warrant as the absolute owner 
hereof for all purposes; PROVIDED, HOWEVER, that if this Warrant is properly 
assigned in blank, the Company may (but shall not be required to) treat the 
bearer hereof as the absolute owner hereof for all purposes, notwithstanding 
any notice to the contrary.  Any Registered Holder may change such Registered 
Holder's address as shown on the warrant register by written notice to the 
Company requesting such change.

     4. NO IMPAIRMENT.  The Company will not, by amendment of its charter or 
through reorganization, consolidation, merger, dissolution, sale of assets or 
any other voluntary action, avoid or seek to avoid the observance or 
performance of any of the terms of this Warrant, but will (subject to Section 
13 below) at all times in good faith assist in the carrying out of all such 
terms and in the taking of all such action as may be necessary or appropriate 
in order to protect the rights of the holder of this Warrant against 
impairment.

     5. TERMINATION.  This Warrant (and the right to purchase securities upon 
exercise hereof) shall terminate upon the earliest to occur of the following 
(the "EXPIRATION DATE"): (a) February 27, 2003, or (b) the effective date of 
the sale, conveyance, disposal, or encumbrance of all or substantially all of 
the Company's property or business or the Company's merger into or 
consolidation with any other corporation (other than a wholly-owned 
subsidiary corporation) or any other transaction or series of related 
transactions in which more than fifty percent (50%) of the voting power of 
the Company is disposed of, PROVIDED that this Section 5(b) shall not apply a 
merger effected exclusively for the purpose of changing the domicile of the 
Company.

     6. NOTICES OF CERTAIN TRANSACTIONS.  In case:

        (a) the Company shall take a record of the holders of its Common 
Stock (or other stock or securities at the time deliverable upon the exercise 
of this Warrant) for the purpose of entitling or enabling them to receive any 
dividend or other distribution, or to receive any right to

<PAGE>

subscribe for or purchase any shares of stock of any class or any other 
securities, or to receive any other right, to subscribe for or purchase any 
shares of stock of any class or any other securities, or to receive any other 
right, or

        (b) of any capital reorganization of the Company, any 
reclassification of the capital stock of the Company, any consolidation or 
merger of the Company, any consolidation or merger of the Company with or 
into another corporation (other than a consolidation or merger in which the 
Company is the surviving entity), or any transfer of all or substantially all 
of the assets of the Company, or 

        (c) of the voluntary or involuntary dissolution, liquidation or 
winding-up of the Company,

then, and in each such case, the Company will mail or cause to be mailed to 
the Registered Holder of this Warrant a notice specifying, as the case may 
be, (i) the date on which a record is to be taken for the purpose of such 
dividend, distribution or right, and stating the amount and character of such 
dividend, distribution or right, or (ii) the effective date on which such 
reorganization, reclassification, consolidation, merger, transfer, 
dissolution, liquidation or winding-up is to take place, and the time, if any 
is to be fixed, as of which the holders of record of Common Stock (or such 
other stock or securities at the time deliverable upon such reorganization, 
reclassification, consolidation, merger, transfer, dissolution, liquidation 
or winding-up) are to be determined.  Such notice shall be mailed at least 
ten (10) days prior to the record date or effective date for the event 
specified in such notice.

     7. RESERVATION OF STOCK.  The Company will at all times reserve and keep 
available, solely for the issuance and delivery upon the exercise of this 
Warrant, such shares of Warrant Stock and other stock, securities and 
property, as from time to time shall be issuable upon the exercise of this 
Warrant.

     8. EXCHANGE OF WARRANTS.  Upon the surrender by the Registered Holder of 
any Warrant or Warrants, properly endorsed, to the Company at the principal 
office of the Company, the Company will, subject to the provisions of Section 
3 hereof, issue and deliver to or upon the order of such Holder, at the 
Company's expense, a new Warrant or Warrants of like tenor, in the name of 
such Registered Holder or as such Registered Holder (upon payment by such 
Registered Holder of any applicable transfer taxes) may direct, calling in 
the aggregate on the face or faces thereof for the number of shares of Common 
Stock called for on the face or faces of the Warrant or Warrants so 
surrendered.

     9. REPLACEMENT OF WARRANTS.  Upon receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and (in the case of loss, theft or destruction) upon delivery of 
an indemnity agreement (with surety if reasonably required) in an amount 
reasonably satisfactory to the Company, or (in the case of mutilation) upon 
surrender and cancellation of this Warrant, the Company will issue, in lieu 
thereof, a new Warrant of like tenor.

    10. NOTICES.  Any notice required or permitted by this Warrant shall be 
in writing and shall be deemed sufficient upon receipt, when delivered 
personally or by courier, overnight delivery service or confirmed facsimile, 
or forty-eight (48) hours after being deposited in the regular mail as

<PAGE>

certified or registered mail (airmail if sent internationally) with postage 
prepaid, addressed (a) if to the Registered Holder, to the address of the 
Registered Holder most recently furnished in writing to the Company and (b) 
if to the Company, to the address set forth below or subsequently modified by 
written notice to the Registered Holder.

    11. NO RIGHTS AS SHAREHOLDER.  Until the exercise of this Warrant, the 
Registered Holder of this Warrant shall not have or exercise any rights by 
virtue hereof as a shareholder of the Company.

    12. NO FRACTIONAL SHARES.  No fractional shares of Common Stock will be 
issued in connection with any exercise hereunder.  In lieu of any fractional 
shares which would otherwise be issuable, the Company shall pay cash equal to 
the product of such fraction multiplied by the fair market value of one share 
of Common Stock on the date of exercise, as determined in good faith by the 
Company's Board of Directors.

    13. AMENDMENT OR WAIVER.  Any term of this Warrant may be amended or 
waived only by an instrument in writing signed by the party against which 
enforcement of the amendment or waiver is sought.

    14. HEADINGS.  The headings in this Warrant are for purposes of reference 
only and shall not limit or otherwise affect the meaning of any provision of 
this Warrant.

    15. GOVERNING LAW. This Warrant shall be governed, construed and 
interpreted in accordance with the laws of the State of California, without 
giving effect to principles of conflicts of law.

    16. REGISTRATION OF SECURITIES.

        (a) As soon as possible after the original date of issuance of this 
Warrant, the Company shall use its best efforts to prepare and file a 
registration statement on Form S-3 (the "REGISTRATION STATEMENT") with the 
Commission under the Act to register the resale of the Common Stock issuable 
upon exercise of the Warrant ("REGISTRABLE SECURITIES") and thereafter shall 
use its best efforts to secure the effectiveness of such Registration 
Statement.

        (b) The Company shall pay all Registration Expenses (as defined 
below) in connection with any registration, qualification or compliance 
hereunder, and Purchaser or any transferee of the Registrable Securities 
(each, a "HOLDER") shall pay all Selling Expenses (as defined below) and 
other expenses that are not Registration Expenses relating to the Registrable 
Securities resold by Holder. "Registration Expenses" shall mean all expenses, 
except for Selling Expenses, incurred by the Company in complying with the 
registration provisions herein described, including, without limitation, all 
registration, qualification and filing fees, printing expenses, fees and 
disbursements of counsel for the Company and the Holder (in an amount for 
Holder's counsel not to exceed $5,000), blue sky fees and expenses and the 
expense of any special audits incident to or required by any such 
registration.  "Selling Expenses" shall mean all selling commissions, 
brokerage or underwriting fees and stock transfer taxes applicable to the 
Registrable Securities and all fees and disbursements of counsel for Holder 
in excess of $5,000.

<PAGE>

        (c) In the case of any registration effected by the Company pursuant 
to these registration provisions, and subject to the limitations on 
registration set forth in Section 16(d) below, the Company will use 
commercially reasonable efforts to:  (i) keep such registration effective 
until two (2) years after the issuance date set forth on page 1 hereof; (ii) 
prepare and file with the Commission such amendments and supplements to such 
Registration Statement and the prospectus used in connection with such 
Registration Statement as may be necessary to comply with the provisions of 
the Act with respect to the disposition of all securities covered by such 
Registration Statement; (iii) furnish such number of prospectuses and other 
documents incident thereto, including any amendment of or supplement to the 
prospectus, as a Holder from time to time may reasonably request; (iv) 
register and qualify the securities covered by such Registration Statement 
under such other securities or Blue Sky laws of such jurisdictions as shall 
be reasonably requested by the Holders, provided that the Company shall not 
be required in connection therewith or as a condition thereto to qualify to 
do business or to file a general consent to service of process in any such 
states or jurisdictions; (v) cause all such Registrable Securities registered 
as described herein to be listed on each securities exchange and quoted on 
each quotation service on which similar securities issued by the Company are 
then listed or quoted; and (vi) otherwise use commercially reasonable efforts 
to comply with all applicable rules and regulations of the Commission.

        (d) The Company may, by written notice to Holder, delay the filing or 
effectiveness of, or suspend, the Registration Statement, and require that 
Holder immediately cease sales of shares pursuant to such Registration 
Statement in any period during which the Company is engaged in any activity 
or transaction or preparations or negotiations for any activity or 
transaction ("COMPANY ACTIVITY") that the Company desires to keep 
confidential for business reasons, if the Company determines in good faith 
that the public disclosure requirements imposed on the Company under the Act 
in connection with the Registration Statement would require disclosure of the 
Company Activity; provided, however, that (A) the Company shall use 
commercially reasonable efforts to minimize the length of any such period of 
delay or suspension, (B) any such delay or suspension shall be applied in the 
same manner to any other resale registration statement then in effect, (C) no 
such suspension period shall extend longer than forty-five (45) consecutive 
calendar days, (D) no such suspension period may be imposed within forty-five 
(45) days following the completion of a prior suspension period, and (E) the 
Company shall not impose suspension periods which, in the aggregate, exceed 
ninety (90) days in any twelve (12) month period.  If the Company delays or 
suspends the Registration Statement or requires Holder to cease sales of 
shares pursuant to this Section 4(d), the Company shall, as promptly as 
practicable following the termination of the circumstance which entitled the 
Company to do so, take such actions as may be necessary to file or reinstate 
the effectiveness of the Registration Statement and/or give written notice to 
Holder authorizing it to resume sales pursuant to such Registration 
Statement.  If as a result thereof the prospectus included in the 
Registration Statement has been amended to comply with the requirements of 
the Act, the Company shall enclose such revised prospectus with the notice to 
Holders given pursuant to this Section 4(d), and Holder shall make no offers 
or sales of shares pursuant to the Registration Statement other than by means 
of such revised prospectus.  If the Company delays or suspends the 
Registration Statement or requires Holder to cease sales of shares pursuant 
to this Section 4(d), the Company shall extend the period during which it 
maintains effectiveness of the Registration Statement by the number of days 
of any such period of delay or suspension.

<PAGE>

        (e) Holder hereby agrees to comply with the registration provisions 
herein described.  Holder will only sell Registrable Securities at such time 
that information required to be included in the Registration Statement and 
previously supplied by Holder is accurate.  The Company shall furnish to 
Holder a reasonable number of copies of a supplement to or an amendment of 
such prospectus as may be necessary so that, as thereafter delivered to the 
Holders of such shares, such prospectus shall not include an untrue statement 
of a material fact or omit to state a material fact required to be stated 
therein or necessary to make the statements therein not misleading or 
incomplete in the light of the circumstances then existing.  Holder agrees 
that the Company may impose a legend setting forth the provisions of 
Section 16(e) on the Registrable Securities during the period of registration.

        (f) With a view to making available to the holders the benefits of 
Rule 144 promulgated under the Act and any other rule or regulation of the 
Commission that may at any time permit Holder to sell Registrable Securities 
to the public without registration or pursuant to a registration on Form S-3, 
the Company hereby covenants and agrees to:  (i) make and keep public 
information available, as those terms are understood and defined in Rule 144, 
at all times after the issuance of this Warrant; and (ii) file with the 
Commission in a timely manner all reports and other documents required of the 
Company under the Act and Exchange Act.

        (g) Indemnification.

              (i) To the extent permitted by law, the Company will indemnify 
and hold harmless Holder, any underwriter (as defined in the Act) for Holder, 
its officers, directors, shareholders or partners and each person, if any, 
who controls Holder or underwriter within the meaning of the Act or the 
Exchange Act, against any losses, claims, damages, or liabilities to which 
they may become subject under the Act, the Exchange Act or other federal or 
state law, insofar as such losses, claims, damages, or liabilities (or 
actions in respect thereof) arise out of or are based upon any of the 
following statements, omissions or violations (collectively a "VIOLATION"):  
(A) any untrue statement or alleged untrue statement of a material fact 
contained in such Registration Statement, including any preliminary 
prospectus or final prospectus contained therein or any amendments or 
supplements thereto or (B) the omission or alleged omission to state therein 
a material fact required to be stated therein, or necessary to make the 
statements therein not misleading; and the Company will pay to each such 
Holder, underwriter or controlling person, as incurred, any legal or other 
expenses reasonably incurred by them in connection with investigating or 
defending any such loss, claim, damage, liability, or action; provided, 
however, that the indemnity agreement contained in this Section 16(g)(i) 
shall not apply to amounts paid in settlement of any such loss, claim, 
damage, liability, or action if such settlement is effected without the 
consent of the Company (which consent shall not be unreasonably withheld), 
nor shall the Company be liable in any such case for any such loss, claim, 
damage, liability, or action to the extent that it arises out of or is based 
upon a Violation which occurs in reliance upon and in conformity with written 
information furnished expressly for use in connection with such registration 
by any such Holder, underwriter or controlling person; further provided, 
however, that the foregoing indemnity with respect to any untrue statement  
in or omission from any preliminary prospectus shall not inure to the benefit 
of any Holder from whom the person asserting any such losses, claims, damages 
or liabilities purchased the Registrable Securities if a copy of the final 
prospectus or any amendment thereto had not been sent or given to such person 
at or prior to the written confirmation of the sale

<PAGE>

of such Registrable Securities to such person if required by the Act and the 
untrue statement or omission of a material fact contained in such preliminary 
prospectus was corrected in the final prospectus or amendment and such final 
prospectus or amendment was distributed to the Holder prior to such sale of 
Registrable Securities.

             (ii) To the extent permitted by law, each selling Holder will 
indemnify and hold harmless the Company, each of its directors, each of its 
officers who has signed the Registration Statement, each person, if any, who 
controls the Company within the meaning of the Act, any underwriter, any 
other Holder selling securities in such Registration Statement and any 
controlling person of any such underwriter or other Holder, against any 
losses, claims, damages, or liabilities to which any of the foregoing persons 
may become subject, under the Act, the Exchange Act or other federal or state 
law, insofar as such losses, claims, damages, or liabilities (or actions in 
respect thereto) arise out of or are based upon any Violation, in each case 
to the extent (and only to the extent) that such Violation occurs in reliance 
upon and in conformity with written information furnished by such Holder 
expressly for use in connection with such registration; and each such Holder 
will pay, as incurred, any legal or other expenses reasonably incurred by any 
person intended to be indemnified pursuant to this subsection 16(g)(ii), in 
connection with investigating or defending any such loss, claim, damage, 
liability, or action; provided, however, that the indemnity agreement 
contained in this subsection 16 (g)(ii) shall not apply to amounts paid in 
settlement of any such loss, claim, damage, liability or action if such 
settlement is effected without the consent of the Holder, which consent shall 
not be unreasonably withheld; provided, that, in no event shall any indemnity 
under this subsection 16(g)(ii) exceed the net proceeds from the offering 
received by such Holder, except in the case of willful fraud by such Holder.

            (iii) Promptly after receipt by an indemnified party under this 
Section 16(g) of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying party under this Section 
16(g), deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party similarly noticed, to assume the defense thereof with 
counsel mutually satisfactory to the parties; provided, however, that an 
indemnified party (together with all other indemnified parties which may be 
represented without conflict by one counsel) shall have the right to retain 
one separate counsel, with the reasonable fees and expenses to be paid by the 
indemnifying party, if representation of such indemnified party by the 
counsel retained by the indemnifying party would be inappropriate due to 
actual or potential differing interests between such indemnified party and 
any other party represented by such counsel in such proceeding.  The failure 
to deliver written notice to the indemnifying party within a reasonable time 
of the commencement of any such action, if and only if prejudicial to its 
ability to defend such action, shall relieve such indemnifying party of any 
liability to the indemnified party under this Section 16(g).

    17. RESALE RESTRICTIONS.  Holder agrees that it will not sell any 
Registrable Securities issued hereunder until the effectiveness of the 
Registration Statement to be filed pursuant to Section 16 above.  
Notwithstanding the foregoing, the Company may suspend resales by the Holder 
if an underwriter reasonably determines that such resales would adversely 
affect the Company's ability to raise additional capital in a public offering 
of the Company's equity securities

<PAGE>

and such underwriter issues a written opinion to the Company to that effect.  
Any such suspension of resales by the Holder pursuant to the foregoing 
sentence will not exceed 120 calendar days commencing on the date of the 
secondary offering.   The volume and resale restrictions set forth in this 
Section 17 shall be set forth in any and all Registration Statements brought 
effective pursuant to Section 16 above, and the Company shall instruct its 
transfer agent, broker dealers and market makers to enforce the volume 
restrictions set forth herein.  If the Company suspends resales by the Holder 
pursuant to this Section 17, the Company shall extend the period during which 
it maintains effectiveness of the Registration Statement by the number of 
days of any such period of suspension.

                         CENTURA SOFTWARE CORPORATION

                         COMMON STOCK PURCHASE WARRANT
                         -----------------------------

     Centura Software Corporation (the "COMPANY"), for value received, hereby 
certifies that Rochon Capital Group, Ltd., or its registered assigns (the 
"REGISTERED HOLDER"), is entitled, subject to the terms set forth below, to 
purchase from the Company, at any time after the date hereof and on or before 
the Expiration Date (as defined in Section 5 below), up to 71,698 shares (as 
adjusted from time to time pursuant to the provisions of this Warrant) of 
Common Stock of the Company, at a purchase price of $2.12 per share.  The 
shares purchasable upon exercise of this Warrant and the purchase price per 
share, as adjusted from time to time pursuant to the provisions of this 
Warrant, are sometimes hereinafter referred to as the "WARRANT STOCK" and the 
"PURCHASE PRICE," respectively.

    1. EXERCISE.

       (a) MANNER OF EXERCISE.  This Warrant may be exercised by the 
Registered Holder, in whole or in part, by surrendering this Warrant, with 
the purchase form appended hereto as EXHIBIT A duly executed by such 
Registered Holder or by such Registered Holder's duly authorized attorney, at 
the principal office of the Company, or at such other office or agency as the 
Company may designate, accompanied by payment in full of the Purchase Price 
payable in respect of the number of shares of Warrant Stock purchased upon 
such exercise.  The Purchase Price may be paid by cash, check or wire 
transfer to the Registered Holder.  

        (b) EFFECTIVE TIME OF EXERCISE.  Each exercise of this Warrant shall 
be deemed to have been effected immediately prior to the close of business on 
the day on which this Warrant shall have been surrendered to the Company as 
provided in Section 1(a) above.  At such time, the person or persons in whose 
name or names any certificates for Warrant Stock shall be issuable upon such 
exercise as provided in Section 1(d) below shall be deemed to have become the 
holder or holders of record of the Warrant Stock represented by such 
certificates.

        (c) NET ISSUE EXERCISE.

             (i) In lieu of exercising this Warrant in the manner provided 
above in Section 1(a), the Registered Holder may elect to receive shares equal 
to the value of this Warrant (or the portion thereof being canceled) by 
surrender of this Warrant at the principal office of the

<PAGE>

Company together with notice of such election in which event the Company 
shall issue to holder a number of shares of Common Stock computed using the 
following formula:

                            X = Y (A - B)
                                ---------
                                    A

Where  X = The number of shares of Common Stock to be issued to the 
           Registered Holder.

       Y = The number of shares of Common Stock as to which the Warrant is 
           being exercised

       A = The fair market value of one share of Common Stock (at the date of 
           such calculation).

       B = The Purchase Price (as adjusted to the date of such calculation).

           (ii) For purposes of this Section 1(c), the fair market value of 
one share of Common Stock on the date of calculation shall mean:

                (1) if the Company's Common Stock is traded on a securities 
exchange, The Nasdaq Stock Market, or The Nasdaq SmallCap Market, the fair 
market value shall be deemed to be the closing price on the trading day 
immediately preceding the date of exercise of the Warrant; or

                (2) if the Company's Common Stock is actively traded 
over-the-counter, the fair market value shall be deemed to be the closing bid 
or sales price (whichever is applicable) on the trading day immediately 
preceding the date of exercise of the Warrant; or

                (3) if neither (1) nor (2) is applicable, the fair market 
value shall be at the highest price per share which the Company could obtain 
on the date of calculation from a willing buyer (not a current employee or 
director) for shares of Common Stock sold by the Company, from authorized but 
unissued shares, as determined in good faith by the Board of Directors, 
unless the Company is at such time subject to an acquisition as described in 
Section 5(b) below, in which case the fair market value per share of Common 
Stock shall be deemed to be the value of the consideration per share received 
by the holders of such stock pursuant to such acquisition.

       (d) DELIVERY TO HOLDER.  As soon as practicable after the exercise of 
this Warrant in whole or in part, and in any event within three (3) days 
thereafter, the Company at its expense will cause to be issued in the name 
of, and delivered to, the Registered Holder, or as such Holder (upon payment 
by such Holder of any applicable transfer taxes) may direct:

            (i) a certificate or certificates for the number of shares of 
Warrant Stock to which such Registered Holder shall be entitled, and 


<PAGE>

           (ii) in case such exercise is in part only, a new warrant or 
warrants (dated the date hereof) of like tenor, calling in the aggregate on 
the face or faces thereof for the number of shares of Warrant Stock equal 
(without giving effect to any adjustment therein) to the number of such 
shares called for on the face of this Warrant minus the number of such 
shares purchased by the Registered Holder upon such exercise as provided in 
Section 1(a) above.

     2. ADJUSTMENTS.

        (a) STOCK SPLITS AND DIVIDENDS.  If outstanding shares of the 
Company's Common Stock shall be subdivided into a greater number of shares or 
a dividend in Common Stock shall be paid in respect of Common Stock, the 
Purchase Price in effect immediately prior to such subdivision or at the 
record date of such dividend shall simultaneously with the effectiveness of 
such subdivision or immediately after the record date of such dividend be 
proportionately reduced.  If outstanding shares of Common Stock shall be 
combined into a smaller number of shares, the Purchase Price in effect 
immediately prior to such combination shall, simultaneously with the 
effectiveness of such combination, be proportionately increased.  When any 
adjustment is required to be made in the Purchase Price, the number of shares 
of Warrant Stock purchasable upon the exercise of this Warrant shall be 
changed to the number determined by dividing (i) an amount equal to the 
number of shares issuable upon the exercise of this Warrant immediately prior 
to such adjustment, multiplied by the Purchase Price in effect immediately 
prior to such adjustment, by (ii) the Purchase Price in effect immediately 
after such adjustment.

       (b) RECLASSIFICATION, ETC.  In case of any reclassification or change 
of the outstanding securities of the Company or of any reorganization of the 
Company (or any other corporation the stock or securities of which are at the 
time receivable upon the exercise of this Warrant) or any similar corporate 
reorganization or merger or conveyance on or after the date hereof, then and in 
each such case the holder of this Warrant, upon the exercise hereof at any time 
after the consummation of such reclassification, change, reorganization, merger 
or conveyance, shall be entitled to receive, in lieu of the stock or other 
securities and property receivable upon the exercise hereof prior to such 
consummation, the stock or other securities or property to which such holder 
would have been entitled upon such consummation if such holder had exercised 
this Warrant immediately prior thereto, all subject to further adjustment as 
provided in Section 2(a); and in each such case, the terms of this Section 2 
shall be applicable to the shares of stock or other securities properly receiv-
able upon the exercise of this Warrant after such consummation.

       (c) ADJUSTMENT CERTIFICATE.  When any adjustment is required to be 
made in the Purchase Price, the Company shall promptly mail to the Registered 
Holder a certificate setting forth the Purchase Price after such adjustment 
and setting forth a brief statement of the facts requiring such adjustment.  
Such certificate shall also set forth the kind and amount of stock or other 
securities or property into which this Warrant shall be exercisable following 
the occurrence of any of the events specified in Section 2(a) or 2(b) above.

     3. TRANSFERS.  

        (a) UNREGISTERED SECURITY.  Each holder of this Warrant acknowledges 
that this Warrant and the Warrant Stock have not been registered under the 
Securities Act, and agrees not to sell, pledge, distribute, offer for sale, 
transfer or otherwise dispose of this Warrant or any Warrant


<PAGE>

Stock issued upon its exercise in the absence of (i) an effective 
registration statement under the Act as to this Warrant or such Warrant Stock 
and registration or qualification of this Warrant or such Warrant Stock under 
any applicable U.S. federal or state securities law then in effect or (ii) an 
opinion of counsel, satisfactory to the Company, that such registration and 
qualification are not required.  Each certificate or other instrument for 
Warrant Stock issued upon the exercise of this Warrant shall bear a legend 
substantially to the foregoing effect until such time as the registration of 
the Warrant Stock is effective or until such time as the Warrant Stock has 
been held by the holder (after giving effect to permissible tacking under 
Rule 144) for at least two years, at and after which time no legend shall be 
required.

        (b) TRANSFERABILITY.  Subject to the provisions of Section 3(a) 
hereof, this Warrant and all rights hereunder are transferable, in whole or 
in part, upon surrender of the Warrant with a properly executed assignment 
(in the form of EXHIBIT B hereto) at the principal office of the Company, 
PROVIDED, HOWEVER, that this Warrant may not be transferred in part unless 
the transferee and any subsequent tranferee acquires the right to purchase at 
least 25,000 shares (as adjusted pursuant to Section 2) of Warrant Stock 
hereunder.

        (c) WARRANT REGISTER.  The Company will maintain a register 
containing the names and addresses of the Registered Holders of this Warrant. 
 Until any transfer of this Warrant is made in the warrant register, the 
Company may treat the Registered Holder of this Warrant as the absolute owner 
hereof for all purposes; PROVIDED, HOWEVER, that if this Warrant is properly 
assigned in blank, the Company may (but shall not be required to) treat the 
bearer hereof as the absolute owner hereof for all purposes, notwithstanding 
any notice to the contrary.  Any Registered Holder may change such Registered 
Holder's address as shown on the warrant register by written notice to the 
Company requesting such change.

     4. NO IMPAIRMENT.  The Company will not, by amendment of its charter or 
through reorganization, consolidation, merger, dissolution, sale of assets or 
any other voluntary action, avoid or seek to avoid the observance or 
performance of any of the terms of this Warrant, but will (subject to Section 
13 below) at all times in good faith assist in the carrying out of all such 
terms and in the taking of all such action as may be necessary or appropriate 
in order to protect the rights of the holder of this Warrant against 
impairment.

     5. TERMINATION.  This Warrant (and the right to purchase 
securities upon exercise hereof) shall terminate upon the earliest to occur 
of the following (the "EXPIRATION DATE"): (a) February 27, 2003, or (b) the 
effective date of the sale, conveyance, disposal, or encumbrance of all or 
substantially all of the Company's property or business or the Company's 
merger into or consolidation with any other corporation (other than a 
wholly-owned subsidiary corporation) or any other transaction or series of 
related transactions in which more than fifty percent (50%) of the voting 
power of the Company is disposed of, PROVIDED that this Section 5(b) shall 
not apply a merger effected exclusively for the purpose of changing the 
domicile of the Company.

     6. NOTICES OF CERTAIN TRANSACTIONS.  In case:

        (a) the Company shall take a record of the holders of its Common 
Stock (or other stock or securities at the time deliverable upon the exercise 
of this Warrant) for the purpose of entitling or enabling them to receive any 
dividend or other distribution, or to receive any right to

<PAGE>

subscribe for or purchase any shares of stock of any class or any other 
securities, or to receive any other right, to subscribe for or purchase any 
shares of stock of any class or any other securities, or to receive any other 
right, or

        (b) of any capital reorganization of the Company, any 
reclassification of the capital stock of the Company, any consolidation or 
merger of the Company, any consolidation or merger of the Company with or 
into another corporation (other than a consolidation or merger in which the 
Company is the surviving entity), or any transfer of all or substantially all 
of the assets of the Company, or 

        (c) of the voluntary or involuntary dissolution, liquidation or 
winding-up of the Company,

then, and in each such case, the Company will mail or cause to be mailed to 
the Registered Holder of this Warrant a notice specifying, as the case may 
be, (i) the date on which a record is to be taken for the purpose of such 
dividend, distribution or right, and stating the amount and character of such 
dividend, distribution or right, or (ii) the effective date on which such 
reorganization, reclassification, consolidation, merger, transfer, 
dissolution, liquidation or winding-up is to take place, and the time, if any 
is to be fixed, as of which the holders of record of Common Stock (or such 
other stock or securities at the time deliverable upon such reorganization, 
reclassification, consolidation, merger, transfer, dissolution, liquidation 
or winding-up) are to be determined.  Such notice shall be mailed at least 
ten (10) days prior to the record date or effective date for the event 
specified in such notice.

     7. RESERVATION OF STOCK.  The Company will at all times reserve and keep 
available, solely for the issuance and delivery upon the exercise of this 
Warrant, such shares of Warrant Stock and other stock, securities and 
property, as from time to time shall be issuable upon the exercise of this 
Warrant.

     8. EXCHANGE OF WARRANTS.  Upon the surrender by the Registered Holder of 
any Warrant or Warrants, properly endorsed, to the Company at the principal 
office of the Company, the Company will, subject to the provisions of Section 
3 hereof, issue and deliver to or upon the order of such Holder, at the 
Company's expense, a new Warrant or Warrants of like tenor, in the name of 
such Registered Holder or as such Registered Holder (upon payment by such 
Registered Holder of any applicable transfer taxes) may direct, calling in 
the aggregate on the face or faces thereof for the number of shares of Common 
Stock called for on the face or faces of the Warrant or Warrants so 
surrendered.

     9. REPLACEMENT OF WARRANTS.  Upon receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and (in the case of loss, theft or destruction) upon delivery of 
an indemnity agreement (with surety if reasonably required) in an amount 
reasonably satisfactory to the Company, or (in the case of mutilation) upon 
surrender and cancellation of this Warrant, the Company will issue, in lieu 
thereof, a new Warrant of like tenor.

    10. NOTICES.  Any notice required or permitted by this Warrant shall be 
in writing and shall be deemed sufficient upon receipt, when delivered 
personally or by courier, overnight delivery service or confirmed facsimile, 
or forty-eight (48) hours after being deposited in the regular mail as

<PAGE>

certified or registered mail (airmail if sent internationally) with postage 
prepaid, addressed (a) if to the Registered Holder, to the address of the 
Registered Holder most recently furnished in writing to the Company and (b) 
if to the Company, to the address set forth below or subsequently modified by 
written notice to the Registered Holder.

    11. NO RIGHTS AS SHAREHOLDER.  Until the exercise of this Warrant, the 
Registered Holder of this Warrant shall not have or exercise any rights by 
virtue hereof as a shareholder of the Company.

    12. NO FRACTIONAL SHARES.  No fractional shares of Common Stock will be 
issued in connection with any exercise hereunder.  In lieu of any fractional 
shares which would otherwise be issuable, the Company shall pay cash equal to 
the product of such fraction multiplied by the fair market value of one share 
of Common Stock on the date of exercise, as determined in good faith by the 
Company's Board of Directors.

    13. AMENDMENT OR WAIVER.  Any term of this Warrant may be amended or 
waived only by an instrument in writing signed by the party against which 
enforcement of the amendment or waiver is sought.

    14. HEADINGS.  The headings in this Warrant are for purposes of reference 
only and shall not limit or otherwise affect the meaning of any provision of 
this Warrant.

    15. GOVERNING LAW. This Warrant shall be governed, construed and 
interpreted in accordance with the laws of the State of California, without 
giving effect to principles of conflicts of law.

    16. REGISTRATION OF SECURITIES.

        (a) As soon as possible after the original date of issuance of this 
Warrant, the Company shall use its best efforts to prepare and file a 
registration statement on Form S-3 (the "REGISTRATION STATEMENT") with the 
Commission under the Act to register the resale of the Common Stock issuable 
upon exercise of the Warrant ("REGISTRABLE SECURITIES") and thereafter shall 
use its best efforts to secure the effectiveness of such Registration 
Statement.

        (b) The Company shall pay all Registration Expenses (as defined 
below) in connection with any registration, qualification or compliance 
hereunder, and Purchaser or any transferee of the Registrable Securities 
(each, a "HOLDER") shall pay all Selling Expenses (as defined below) and 
other expenses that are not Registration Expenses relating to the Registrable 
Securities resold by Holder. "Registration Expenses" shall mean all expenses, 
except for Selling Expenses, incurred by the Company in complying with the 
registration provisions herein described, including, without limitation, all 
registration, qualification and filing fees, printing expenses, fees and 
disbursements of counsel for the Company and the Holder (in an amount for 
Holder's counsel not to exceed $5,000), blue sky fees and expenses and the 
expense of any special audits incident to or required by any such 
registration.  "Selling Expenses" shall mean all selling commissions, 
brokerage or underwriting fees and stock transfer taxes applicable to the 
Registrable Securities and all fees and disbursements of counsel for Holder 
in excess of $5,000.


<PAGE>

        (c) In the case of any registration effected by the Company pursuant 
to these registration provisions, and subject to the limitations on 
registration set forth in Section 16(d) below, the Company will use 
commercially reasonable efforts to:  (i) keep such registration effective 
until two (2) years after the issuance date set forth on page 1 hereof; (ii) 
prepare and file with the Commission such amendments and supplements to such 
Registration Statement and the prospectus used in connection with such 
Registration Statement as may be necessary to comply with the provisions of 
the Act with respect to the disposition of all securities covered by such 
Registration Statement; (iii) furnish such number of prospectuses and other 
documents incident thereto, including any amendment of or supplement to the 
prospectus, as a Holder from time to time may reasonably request; (iv) 
register and qualify the securities covered by such Registration Statement 
under such other securities or Blue Sky laws of such jurisdictions as shall 
be reasonably requested by the Holders, provided that the Company shall not 
be required in connection therewith or as a condition thereto to qualify to 
do business or to file a general consent to service of process in any such 
states or jurisdictions; (v) cause all such Registrable Securities registered 
as described herein to be listed on each securities exchange and quoted on 
each quotation service on which similar securities issued by the Company are 
then listed or quoted; and (vi) otherwise use commercially reasonable efforts 
to comply with all applicable rules and regulations of the Commission.

        (d) The Company may, by written notice to Holder, delay the filing or 
effectiveness of, or suspend, the Registration Statement, and require that 
Holder immediately cease sales of shares pursuant to such Registration 
Statement in any period during which the Company is engaged in any activity 
or transaction or preparations or negotiations for any activity or 
transaction ("COMPANY ACTIVITY") that the Company desires to keep 
confidential for business reasons, if the Company determines in good faith 
that the public disclosure requirements imposed on the Company under the Act 
in connection with the Registration Statement would require disclosure of the 
Company Activity; provided, however, that (A) the Company shall use 
commercially reasonable efforts to minimize the length of any such period of 
delay or suspension, (B) any such delay or suspension shall be applied in the 
same manner to any other resale registration statement then in effect, (C) no 
such suspension period shall extend longer than forty-five (45) consecutive 
calendar days, (D) no such suspension period may be imposed within forty-five 
(45) days following the completion of a prior suspension period, and (E) the 
Company shall not impose suspension periods which, in the aggregate, exceed 
ninety (90) days in any twelve (12) month period.  If the Company delays or 
suspends the Registration Statement or requires Holder to cease sales of 
shares pursuant to this Section 4(d), the Company shall, as promptly as 
practicable following the termination of the circumstance which entitled the 
Company to do so, take such actions as may be necessary to file or reinstate 
the effectiveness of the Registration Statement and/or give written notice to 
Holder authorizing it to resume sales pursuant to such Registration 
Statement.  If as a result thereof the prospectus included in the 
Registration Statement has been amended to comply with the requirements of 
the Act, the Company shall enclose such revised prospectus with the notice to 
Holders given pursuant to this Section 4(d), and Holder shall make no offers 
or sales of shares pursuant to the Registration Statement other than by means 
of such revised prospectus.  If the Company delays or suspends the 
Registration Statement or requires Holder to cease sales of shares pursuant 
to this Section 4(d), the Company shall extend the period during which it 
maintains effectiveness of the Registration Statement by the number of days 
of any such period of delay or suspension.


<PAGE>

        (e) Holder hereby agrees to comply with the registration provisions 
herein described.  Holder will only sell Registrable Securities at such time 
that information required to be included in the Registration Statement and 
previously supplied by Holder is accurate.  The Company shall furnish to 
Holder a reasonable number of copies of a supplement to or an amendment of 
such prospectus as may be necessary so that, as thereafter delivered to the 
Holders of such shares, such prospectus shall not include an untrue statement 
of a material fact or omit to state a material fact required to be stated 
therein or necessary to make the statements therein not misleading or 
incomplete in the light of the circumstances then existing.  Holder 
agrees that the Company may impose a legend setting forth the provisions of 
Section 16(e) on the Registrable Securities during the period of registration.

        (f) With a view to making available to the holders the benefits of 
Rule 144 promulgated under the Act and any other rule or regulation of the 
Commission that may at any time permit Holder to sell Registrable Securities 
to the public without registration or pursuant to a registration on Form S-3, 
the Company hereby covenants and agrees to:  (i) make and keep public 
information available, as those terms are understood and defined in Rule 144, 
at all times after the issuance of this Warrant; and (ii) file with the 
Commission in a timely manner all reports and other documents required of the 
Company under the Act and Exchange Act.

        (g) INDEMNIFICATION.

             (i) To the extent permitted by law, the Company will indemnify 
and hold harmless Holder, any underwriter (as defined in the Act) for Holder, 
its officers, directors, shareholders or partners and each person, if any, 
who controls Holder or underwriter within the meaning of the Act or the 
Exchange Act, against any losses, claims, damages, or liabilities to which 
they may become subject under the Act, the Exchange Act or other federal or 
state law, insofar as such losses, claims, damages, or liabilities (or 
actions in respect thereof) arise out of or are based upon any of the 
following statements, omissions or violations (collectively a "Violation"):  
(A) any untrue statement or alleged untrue statement of a material fact 
contained in such Registration Statement, including any preliminary 
prospectus or final prospectus contained therein or any amendments or 
supplements thereto or (B) the omission or alleged omission to state therein 
a material fact required to be stated therein, or necessary to make the 
statements therein not misleading; and the Company will pay to each such 
Holder, underwriter or controlling person, as incurred, any legal or other 
expenses reasonably incurred by them in connection with investigating or 
defending any such loss, claim, damage, liability, or action; provided, 
however, that the indemnity agreement contained in this Section 16(g)(i) 
shall not apply to amounts paid in settlement of any such loss, claim, 
damage, liability, or action if such settlement is effected without the 
consent of the Company (which consent shall not be unreasonably withheld), 
nor shall the Company be liable in any such case for any such loss, claim, 
damage, liability, or action to the extent that it arises out of or is based 
upon a Violation which occurs in reliance upon and in conformity with written 
information furnished expressly for use in connection with such registration 
by any such Holder, underwriter or controlling person; further provided, 
however, that the foregoing indemnity with respect to any untrue statement  
in or omission from any preliminary prospectus shall not inure to the benefit 
of any Holder from whom the person asserting any such losses, claims, damages 
or liabilities purchased the Registrable Securities if a copy of the final 
prospectus or any amendment thereto had not been sent or given to such person 
at or prior to the written confirmation of the sale

<PAGE>

of such Registrable Securities to such person if required by the Act and the 
untrue statement or omission of a material fact contained in such preliminary 
prospectus was corrected in the final prospectus or amendment and such final 
prospectus or amendment was distributed to the Holder prior to such sale of 
Registrable Securities.

            (ii) To the extent permitted by law, each selling Holder will 
indemnify and hold harmless the Company, each of its directors, each of its 
officers who has signed the Registration Statement, each person, if any, who 
controls the Company within the meaning of the Act, any underwriter, any 
other Holder selling securities in such Registration Statement and any 
controlling person of any such underwriter or other Holder, against any 
losses, claims, damages, or liabilities to which any of the foregoing persons 
may become subject, under the Act, the Exchange Act or other federal or state 
law, insofar as such losses, claims, damages, or liabilities (or actions in 
respect thereto) arise out of or are based upon any Violation, in each case 
to the extent (and only to the extent) that such Violation occurs in reliance 
upon and in conformity with written information furnished by such Holder 
expressly for use in connection with such registration; and each such Holder 
will pay, as incurred, any legal or other expenses reasonably incurred by any 
person intended to be indemnified pursuant to this subsection 16(g)(ii), in 
connection with investigating or defending any such loss, claim, damage, 
liability, or action; provided, however, that the indemnity agreement 
contained in this subsection 16 (g)(ii) shall not apply to amounts paid in 
settlement of any such loss, claim, damage, liability or action if such 
settlement is effected without the consent of the Holder, which consent shall 
not be unreasonably withheld; provided, that, in no event shall any indemnity 
under this subsection 16(g)(ii) exceed the net proceeds from the offering 
received by such Holder, except in the case of willful fraud by such Holder.

           (iii) Promptly after receipt by an indemnified party under this 
Section 16(g) of notice of the commencement of any action (including any 
governmental action), such indemnified party will, if a claim in respect 
thereof is to be made against any indemnifying party under this Section 
16(g), deliver to the indemnifying party a written notice of the commencement 
thereof and the indemnifying party shall have the right to participate in, 
and, to the extent the indemnifying party so desires, jointly with any other 
indemnifying party similarly noticed, to assume the defense thereof with 
counsel mutually satisfactory to the parties; provided, however, that an 
indemnified party (together with all other indemnified parties which may be 
represented without conflict by one counsel) shall have the right to retain 
one separate counsel, with the reasonable fees and expenses to be paid by the 
indemnifying party, if representation of such indemnified party by the 
counsel retained by the indemnifying party would be inappropriate due to 
actual or potential differing interests between such indemnified party and 
any other party represented by such counsel in such proceeding.  The failure 
to deliver written notice to the indemnifying party within a reasonable time 
of the commencement of any such action, if and only if prejudicial to its 
ability to defend such action, shall relieve such indemnifying party of any 
liability to the indemnified party under this Section 16(g).

    17. RESALE RESTRICTIONS.  Holder agrees that it will not sell any 
Registrable Securities issued hereunder until the effectiveness of the 
Registration Statement to be filed pursuant to Section 16 above.  
Notwithstanding the foregoing, the Company may suspend resales by the Holder if 
an underwriter reasonably determines that such resales would adversely affect 
the Company's ability to raise additional capital in a public offering of the 
Company's equity securities


<PAGE>

and such underwriter issues a written opinion to the Company to that effect.  
Any such suspension of resales by the Holder pursuant to the foregoing 
sentence will not exceed 120 calendar days commencing on the date of the 
secondary offering.   The volume and resale restrictions set forth in this 
Section 17 shall be set forth in any and all Registration Statements brought 
effective pursuant to Section 16 above, and the Company shall instruct its 
transfer agent, broker dealers and market makers to enforce the volume 
restrictions set forth herein.  If the Company suspends resales by the Holder 
pursuant to this Section 17, the Company shall extend the period during which 
it maintains effectiveness of the Registration Statement by the number of 
days of any such period of suspension.

     4. ADMINISTRATION OF THE PLAN.

(A) the Board or (B) a Committee designated by the Board, which Committee 
shall be constituted in such a manner as to satisfy the legal requirements 
relating to the administration of nonstatutory stock option plans, if any, of 
applicable securities laws and the Code (collectively, the "Applicable 
Laws"). If a Committee has been appointed pursuant to this Section 4(a), such 
Committee shall continue to serve in its designated capacity until otherwise

any Committee and appoint additional members thereof, remove members (with or

vacancies (however caused) and remove all members of a Committee and 
thereafter directly administer the Plan, all to the extent permitted by the 
Applicable Laws.

Plan, and in the case of a Committee, the specific duties delegated by, or

              (i) to grant Options under the Plan; 


<PAGE>

             (ii) to determine, upon review of relevant information and in 
accordance with Section 2(l) of the Plan, the fair market value of the Common 
Stock; 

            (iii) to determine the exercise price per share of Options to 
be granted, which exercise price shall be determined in accordance with 
Section 9(a) of the Plan; 

             (iv) to determine the Employees or Consultants to whom, and the 
time or times at which, Options shall be granted and the number of shares to 
be represented by each Option; 

              (v) to interpret the Plan; 

             (vi) to approve forms of agreement for use under the Plan; 

            (vii) to determine the terms and provisions of each Option 
granted (which need not be identical) and, with the consent of the holder 
thereof, modify or amend each Option; 

           (viii) to accelerate or defer (with the consent of the Optionee) 
the exercise date of any Option; 

             (ix) to authorize any person to execute on behalf of the Company 
any instrument required to effectuate the grant of an Option previously 
granted by the Administrator; and 

              (x) to make all other determinations deemed necessary or 
advisable for the administration of the Plan.

        (c) EFFECT OF ADMINISTRATOR'S DECISION.  All decisions, determinations 
and interpretations of the Administrator shall be final and binding on all 
Optionees and any other holders of any Options granted under the Plan.

     5. ELIGIBILITY.

        (a) Options may be granted only to Employees and Consultants. An 
Employee or Consultant who has been granted an Option may, if Optionee is 
otherwise eligible, be granted an additional Option or Options.

        (b) Each Option shall be designated in the written option agreement 
as a Nonstatutory Stock Option.

        (c) The Plan shall not confer upon any Optionee any right with 
respect to continuation of employment or consulting relationship with the 
Company, nor shall it interfere in any way with Optionee's right or the 
Company's right to terminate Optionee's employment or consulting relationship 
at any time, with or without cause.


<PAGE>

     6. TERM OF PLAN.  The Plan shall become effective upon its adoption by 
the Board of Directors.  It shall continue in effect for a term of ten (10) 
years unless sooner terminated under Section 14 of the Plan.

     7. TERM OF OPTION. The term of each Nonstatutory Stock Option shall be 
ten (10) years from the date of grant thereof or such shorter term as may be 
provided in the Nonstatutory Stock Option Agreement.

     8. EXERCISE PRICE AND CONSIDERATION.

        (a) The per Share exercise price for the Shares to be issued pursuant 
to exercise of an Option shall be such price as is determined by the 
Administrator, but shall be no less than 85% of the fair market value per 
Share on the date of grant.

        (b) The consideration to be paid for the Shares to be issued upon 
exercise of an Option, including the method of payment, shall be determined 
by the Administrator and may consist entirely of (1) cash, (2) check, (3) 
promissory note, (4) other Shares of Common Stock which (i) either have been 
owned by the Optionee for more than six (6) months on the date of surrender 
or were not acquired, directly or indirectly, from the Company, and (ii) have 
a fair market value on the date of surrender equal to the aggregate exercise 
price of the Shares as to which said Option shall be exercised, (5) delivery 
of a properly executed exercise notice together with irrevocable instructions 
to a broker to deliver promptly to the Company the amount of sale or loan 
proceeds required to pay the exercise price, or (6) any combination of such 
methods of payment.  In making its determination as to the type of 
consideration to accept, the Administrator shall consider if acceptance of 
such consideration may be reasonably expected to benefit the Company.

     9. EXERCISE OF OPTION.

        (a) PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER.  Any Option 
granted hereunder shall be exercisable at such times and under such 
conditions as determined by the Administrator, including performance criteria 
with respect to the Company and/or the Optionee, and as shall be permissible 
under the terms of the Plan.

     An Option may not be exercised for a fraction of a Share.

     An Option shall be deemed to be exercised when written notice of such 
exercise has been given to the Company in accordance with the terms of the 
Option by the person entitled to exercise the Option and full payment for the 
Shares with respect to which the Option is exercised has been received by the 
Company.  Full payment may, as authorized by the Administrator, consist of 
any consideration and method of payment allowable under Section 9(b) of the 
Plan.  Until the issuance (as evidenced by the appropriate entry on the books 
of the Company or of a duly authorized transfer agent of the Company) of the 
stock certificate evidencing such Shares, no right to vote or receive 
dividends or any other rights as a shareholder shall exist with respect to 
the Optioned Stock, notwithstanding the exercise of the Option.  The Company 
shall issue (or cause to be issued) such stock certificate promptly upon 
exercise of the 

<PAGE>

Option.  No adjustment will be made for a dividend or other right for which 
the record date is prior to the date the stock certificate is issued, except 
as provided in Section 11 of the Plan.

     Exercise of an Option in any manner shall result in a decrease in the 
number of Shares which thereafter may be available, both for purposes of the 
Plan and for sale under the Option, by the number of Shares as to which the 
Option is exercised.

        (b) TERMINATION OF STATUS AS AN EMPLOYEE OR CONSULTANT.  In the event 
of termination of an Optionee's Continuous Status as an Employee or 
Consultant, such Optionee may, but only within thirty (30) days (or such 
other period of time, not exceeding six (6) months, as is determined by the 
Administrator) after the date of such termination (but in no event later than 
the date of expiration of the term of such Option as set forth in the Option 
Agreement), exercise Optionee's Option to the extent that Optionee was 
entitled to exercise it at the date of such termination.  To the extent that 
Optionee was not entitled to exercise the Option at the date of such 
termination, or if Optionee does not exercise such Option (which Optionee was 
entitled to exercise) within the time specified herein, the Option shall 
terminate.

        (c) DISABILITY OF OPTIONEE.  Notwithstanding the provisions of 
Section 10(b) above, in the event of termination of an Optionee's Continuous 
Status as an Employee or Consultant as a result of Optionee's total and 
permanent disability (as defined in Section 22(e)(3) of the Code), Optionee 
may, but only within twelve (12) months (but in no event later than the date 
of expiration of the term of such Option as set forth in the Option 
Agreement), from the date of such termination (but in no event later than the 
date of expiration of the term of such Option as set forth in the Option 
Agreement), exercise Optionee's Option to the extent Optionee was entitled to 
exercise it at the date of such termination.  To the extent that Optionee was 
not entitled to exercise the Option at the date of termination, or if 
Optionee does not exercise such Option (which Optionee was entitled to 
exercise) within the time specified herein, the Option shall terminate.

        (d) DEATH OF OPTIONEE.  In the event of termination of an Optionee's 
Continuance Status as an Employee or Consultant as a result of the death of 
an Optionee, the Option may be exercised, at any time within twelve (12) 
months following the date of death (but in no event later than the date of 
expiration of the term of such Option as set forth in the Option Agreement), 
by the Optionee's estate or by a person who acquired the right to exercise 
the Option by bequest or inheritance, but only to the extent of the right to 
exercise the Option at the date of death.  To the extent that Optionee was 
not entitled to exercise the Option at the date of death, or if Optionee does 
not exercise such Option to the extent so entitled within the time specified 
herein, the Option shall terminate.

    10. NON-TRANSFERABILITY OF OPTIONS.  The Option may not be sold, pledged, 
assigned, hypothecated, transferred, or disposed of in any manner other than 
by will or by the laws of descent or distribution; PROVIDED, that the 
Administrator may in its discretion grant transferable Nonstatutory Stock 
Options pursuant to option agreements specifying (i) the manner in which such 
Nonstatutory Stock Options are transferable and (ii) that any such transfer 
shall be subject to the Applicable Laws.  The designation of a beneficiary by 
an Optionee will not constitute a

<PAGE>

transfer.  An Option may be exercised, during the lifetime of the Optionee, 
only by the Optionee or a transferee permitted by this Section 11.

    11. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.  

        (a) ADJUSTMENTS.  Subject to any required action by the shareholders 
of the Company, the number of shares of Common Stock covered by each 
outstanding Option, and the number of shares of Common Stock which have been 
authorized for issuance under the Plan but as to which no Options have yet 
been granted or which have been returned to the Plan upon cancellation or 
expiration of an Option, and the price per share of Common Stock covered by 
each such outstanding Option, shall be proportionately adjusted for any 
increase or decrease in the number of issued shares of Common Stock resulting 
from a stock split, reverse stock split, stock dividend, combination or 
reclassification of the Common Stock, or any other increase or decrease in 
the number of issued shares of Common Stock effected without receipt of 
consideration by the Company; provided, however, that conversion of any 
convertible securities of the Company shall not be deemed to have been 
"effected without receipt of consideration." Such adjustment shall be made by 
the Administrator, whose determination in that respect shall be final, 
binding and conclusive.  Except as expressly provided herein, no issuance by 
the Company of shares of stock of any class, or securities convertible into 
shares of stock of any class, shall affect, and no adjustment by reason 
thereof shall be made with respect to, the number or price of shares of 
Common Stock subject to an Option.

        (b) CORPORATE TRANSACTIONS.  In the event of the proposed dissolution 
or liquidation of the Company, the Option will terminate immediately prior to 
the consummation of such proposed action, unless otherwise provided by the 
Administrator.  The Administrator may, in the exercise of its sole discretion 
in such instances, declare that any Option shall terminate as of a date fixed 
by the Administrator and give each Optionee the right to exercise Optionee's 
Option as to all or any part of the Optioned Stock, including Shares as to 
which the Option would not otherwise be exercisable.  In the event of a 
proposed sale of all or substantially all of the assets of the Company, or 
the merger of the Company with or into another corporation, the Option shall 
be assumed or an equivalent option shall be substituted by such successor 
corporation or a parent or subsidiary of such successor corporation, unless 
such successor corporation does not agree to assume the Option or to 
substitute an equivalent option, in which case the Administrator shall, in 
lieu of such assumption or substitution, provide for the Optionee to have the 
right to exercise the Option as to all of the Optioned Stock, including 
Shares as to which the Option would not otherwise be exercisable.  If the 
Administrator makes an Option fully exercisable in lieu of assumption or 
substitution in the event of a merger or sale of assets, the Administrator 
shall notify the Optionee that the Option shall be fully exercisable for a 
period of fifteen (15) days from the date of such notice, and the Option will 
terminate upon the expiration of such period.

    12. TIME OF GRANTING OPTIONS.  The date of grant of an Option shall, for 
all purposes, be the date on which the Administrator makes the determination 
granting such Option.  Notice of the determination shall be given to each 
Employee or Consultant to whom an Option is so granted within a reasonable time 
after the date of such grant.


<PAGE>

    13. AMENDMENT AND TERMINATION OF THE PLAN.

        (a) AMENDMENT AND TERMINATION.  The Board may amend or terminate the 
Plan from time to time in such respects as the Board may deem advisable

        (b) EFFECT OF AMENDMENT OR TERMINATION.  Any such amendment or 
termination of the Plan shall not adversely affect Options already granted 
(except to the extent contemplated by such Options) and such Options shall 
remain in full force and effect, unless mutually agreed otherwise between the 
Optionee and the Board (or other body then administering the Plan), which 
agreement must be in writing and signed by the Optionee and the Company.

    14. CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued 
pursuant to the exercise of an Option unless the exercise of such Option and 
the issuance and delivery of such Shares pursuant thereto shall comply with 
all relevant provisions of law, including, without limitation, the Securities 
Act of 1933, as amended, the Exchange Act, the rules and regulations 
promulgated thereunder, and the requirements of any stock exchange upon which 
the Shares may then be listed, and shall be further subject to the approval 
of counsel for the Company with respect to such compliance.

     As a condition to the exercise of an Option, the Company may require the 
person exercising such Option to represent and warrant at the time of any 
such exercise that the Shares are being purchased only for investment and 
without any present intention to sell or distribute such Shares if, in the 
opinion of counsel for the Company, such a representation is required by any 
of the aforementioned relevant provisions of law.

    15. RESERVATION OF SHARES.  The Company, during the term of this Plan, 
will at all times reserve and keep available such number of Shares as shall be 
sufficient to satisfy the requirements of the Plan.  The inability of the 
Company to obtain authority from any regulatory body having jurisdiction, which 
authority is deemed by the Company's counsel to be necessary to the lawful 
issuance and sale of any Shares hereunder, shall relieve the Company of any 
liability in respect of the failure to issue or sell such Shares as to which 
such requisite authority shall not have been obtained.

    16. OPTION AGREEMENT.  Options shall be evidenced by written option 
agreements in such form as the Administrator shall approve.

    17. INFORMATION TO OPTIONEES.  The Company shall provide to each Optionee 
upon request, during the period for which such Optionee has one or more Options 
outstanding, copies of all annual reports and other information which are 
provided to all shareholders of the Company.  

    18. WITHHOLDING TAXES.  As a condition to the exercise of Options granted 
hereunder, the Optionee shall make such arrangements as the Administrator may 
require for the satisfaction of any federal, state, local or foreign 
withholding tax obligations that may arise in connection

<PAGE>

with the exercise, receipt or vesting of such Option.  The Company shall not 
be required to issue any Shares under the Plan until such obligations are 
satisfied.

    19. STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS.  At the 
discretion of the Administrator, Optionees may satisfy withholding 
obligations as provided in this paragraph.  When an Optionee incurs tax 
liability in connection with an Option which tax liability is subject to tax 
withholding under applicable tax laws, and the Optionee is obligated to pay 
the Company an amount required to be withheld under applicable tax laws, the 
Optionee may satisfy the withholding tax obligation by one or some 
combination of the following methods:  (a) by cash payment, or (b) out of 
Optionee's current compensation, or (c) if permitted by the Administrator, in 
its discretion, by surrendering to the Company Shares that (i) in the case of 
Shares previously acquired from the Company, have been owned by the Optionee 
for more than six months on the date of surrender, and (ii) have a fair 
market value on the date of surrender equal to or less than Optionee's 
marginal tax rate times the ordinary income recognized, or (d) by electing to 
have the Company withhold from the Shares to be issued upon exercise of the 
Option that number of Shares having a fair market value equal to the amount 
required to be withheld.  For this purpose, the fair market value of the 
Shares to be withheld shall be determined on the date that the amount of tax 
to be withheld is to be determined (the "Tax Date").

     All elections by an Optionee to have Shares withheld to satisfy tax 
withholding obligations shall be made in writing in a form acceptable to the 
Administrator and shall be subject to the following restrictions:

        (a) the election must be made on or prior to the applicable Tax Date;

        (b) once made, the election shall be irrevocable as to the particular 
Shares of the Option as to which the election is made; and

        (c) all elections shall be subject to the consent or disapproval of 
the Administrator.

     In the event the election to have Shares withheld is made by an Optionee 
and the Tax Date is deferred under Section 83 of the Code because no election 
is filed under Section 83(b) of the Code, the Optionee shall receive the full 
number of Shares with respect to which the Option is exercised but such 
Optionee shall be unconditionally obligated to tender back to the Company the 
proper number of Shares on the Tax Date.

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

                      NONSTATUTORY STOCK OPTION AGREEMENT
                      -----------------------------------------


    1. GRANT OF OPTION.  Centura Software Corporation, a California 
corporation (the "COMPANY"), hereby grants to the Optionee named in the 
Notice of Stock Option Grant attached to this Agreement ("OPTIONEE"), an 
option (the "OPTION") to purchase the total number of shares of Common Stock 
(the "SHARES") set forth in the Notice of Stock Option Grant, at the exercise 
price per share set forth in the Notice of Stock Option Grant (the "EXERCISE 
PRICE") subject to the terms, definitions and provisions of the 1998 Employee 
Stock Option Plan (the "PLAN") adopted by the Company, which is incorporated 
in this Agreement by reference.  In the event of a conflict between the terms 
of the Plan and the terms of this Agreement, the terms of the Plan shall 
govern.  Unless otherwise defined in this Agreement, the terms used in this 
Agreement shall have the meanings defined in the Plan.

     This Option is intended to be a Nonstatutory Stock Option.

     2. EXERCISE OF OPTION.  This Option shall be exercisable during its term 
in accordance with the Vesting Schedule set out in the Notice of Stock Option 
Grant and with the provisions of Sections 9 and 10 of the Plan as follows:

       (a) RIGHT TO EXERCISE.

            (i) This Option may not be exercised for a fraction of a share.

           (ii) In the event of Optionee's death, disability or other 
termination of employment, the exercisability of the Option is governed 
by Sections 6, 7 and 8 below, subject to the limitations contained in 
paragraph (iii).

          (iii) In no event may this Option be exercised after the date of 
expiration of the term of this Option as set forth in the Notice of Stock 
Option Grant.

      (b) METHOD OF EXERCISE.

           (i) This Option shall be exercisable by delivering to the Company 
a written notice of exercise (in the form attached as EXHIBIT A) which shall 
state the election to exercise the Option, the number of Shares in respect of 
which the Option is being exercised, and such other representations and 
agreements as to the holder's investment intent with respect to such Shares 
of Common Stock as may be required by the Company pursuant to the provisions 
of the Plan.  Such written notice shall be signed by Optionee and shall be 
delivered in person or by certified mail to the Secretary of the Company.  
The written notice shall be accompanied by payment of the Exercise Price.  
This Option shall be deemed to be exercised upon receipt by the Company of 
such written notice accompanied by the Exercise Price.


<PAGE>

          (ii) As a condition to the exercise of this Option, Optionee agrees 
to make adequate provision for federal, state or other tax withholding 
obligations, if any, which arise upon the exercise of the Option or 
disposition of Shares, whether by withholding, direct payment to the Company, 
or otherwise.

         (iii) No Shares will be issued pursuant to the exercise of an Option 
unless such issuance and such exercise shall comply with all relevant 
provisions of law and the requirements of any stock exchange upon which the 
Shares may then be listed.  Assuming such compliance, for income tax purposes 
the Shares shall be considered transferred to Optionee on the date on which 
the Option is exercised with respect to such Shares.

     3. OPTIONEE'S REPRESENTATIONS.  In the event the Shares purchasable 
pursuant to the exercise of this Option have not been registered under the 
Securities Act of 1933, as amended (the "SECURITIES ACT"), at the time this 
Option is exercised, Optionee shall, if required by the Company, concurrently 
with the exercise of all or any portion of this Option, deliver to the 
Company an investment representation statement in customary form, a copy of 
which is available for Optionee's review from the Company upon request.

     4. METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of 
the following, or a combination of the following, at the election of 
Optionee:  (a) cash; (b) check; (c) surrender of other Shares of Common Stock 
of the Company that (i) either have been owned by Optionee for more than six 
(6) months on the date of surrender or were not acquired, directly or 
indirectly, from the Company, and (ii) have a Fair Market Value on the date 
of surrender equal to the aggregate exercise price of the Shares as to which 
said Option shall be exercised; (d) authorization from the Company to retain 
from the total number of Shares as to which the Option is exercised that 
number of Shares having a Fair Market value on the date of exercise equal to 
the exercise price for the total number of Shares as to which the Option is 
exercised; or (e) if there is a public market for the Shares and they are 
registered under the Securities Act, delivery of a properly executed exercise 
notice together with irrevocable instructions to a broker to deliver promptly 
to the Company the amount of sale or loan proceeds required to pay the 
exercise price.

     5. RESTRICTIONS ON EXERCISE.  This Option may not be exercised if 
the issuance of such Shares upon such exercise or the method of payment of 
consideration for such shares would constitute a violation of any applicable 
federal or state securities or other law or regulation, including any 
rule under Part 207 of Title 12 of the Code of Federal Regulations 
("REGULATION G") as promulgated by the Federal Reserve Board.  As a condition 
to the exercise of this Option, the Company may require Optionee to make any 
representation and warranty to the Company as may be required by any 
applicable law or regulation.

     6. TERMINATION OF RELATIONSHIP.  In the event of termination of 
Optionee's Continuous Status as an Employee or Consultant, Optionee may, to 
the extent otherwise so entitled at the date of such termination (the 
"TERMINATION DATE"), exercise this Option during the Termination Period set 
out in the Notice of Stock Option Grant.  To the extent that Optionee was not 
entitled to exercise this Option at the date of such termination, or if 
Optionee does not


<PAGE>

exercise this Option within the time specified in the Notice of Stock Option 
Grant, the Option shall terminate.

     7. DISABILITY OF OPTIONEE.  Notwithstanding the provisions of Section 6 
above, in the event of termination of Optionee's Continuous Status as an 
Employee or Consultant as a result of total and permanent disability (as 
defined in Section 22(e)(3) of the Code), Optionee may, but only within six 
(6) months from the date of termination of employment (but in no event later 
than the date of expiration of the term of this Option as set forth in 
Section 10 below), exercise the Option to the extent otherwise so entitled at 
the date of such termination.  To the extent that Optionee was not entitled 
to exercise the Option at the date of termination, or if Optionee does not 
exercise such Option (to the extent otherwise so entitled) within the time 
specified in this Agreement, the Option shall terminate.

     8. DEATH OF OPTIONEE.  In the event of the death of Optionee:

        (a) during the term of this Option and while an Employee of the 
Company and having been in Continuous Status as an Employee or Consultant 
since the date of grant of the Option, the Option may be exercised, at any 
time within six (6) months following the date of death (but in no event later 
than the date of expiration of the term of this Option as set forth in 
Section 10 below), by Optionee's estate or by a person who acquired the right 
to exercise the Option by bequest or inheritance, but only to the extent of 
the right to exercise that would have accrued had Optionee continued living 
and remained in Continuous Status as an Employee or Consultant three (3) 
months after the date of death, subject to the limitation contained in 
Section 2(i)(d) above in the case of an Incentive Stock Option; or

        (b) within thirty (30) days after the termination of Optionee's 
Continuous Status as an Employee or Consultant, the Option may be exercised, 
at any time within six (6) months following the date of death (but in no 
event later than the date of expiration of the term of this Option as set 
forth in Section 10 below), by Optionee's estate or by a person who acquired 
the right to exercise the Option by bequest or inheritance, but only to the 
extent of the right to exercise that had accrued at the date of termination.

     9. NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in 
any manner otherwise than by will or by the laws of descent or distribution.  
The designation of a beneficiary does not constitute a transfer.  An Option may 
be exercised during the lifetime of Optionee only by Optionee or a transferee 
permitted by this section.  The terms of this Option shall be binding upon the 
executors, administrators, heirs, successors and assigns of Optionee.

    10. TERM OF OPTION.  This Option may be exercised only within the term set 
out in the Notice of Stock Option Grant, and may be exercised during such term 
only in accordance with the Plan and the terms of this Option.

    11. NO ADDITIONAL EMPLOYMENT RIGHTS.  Optionee understands and agrees 
that the vesting of Shares pursuant to the Vesting Schedule is earned only by 
continuing as an Employee or Consultant at the will of the Company (not 
through the act of being hired, being granted this Option or acquiring Shares 
under this Agreement).  Optionee further acknowledges and agrees

<PAGE>

that nothing in this Agreement, nor in the Plan which is incorporated in this 
Agreement by reference, shall confer upon Optionee any right with respect to 
continuation as an Employee or Consultant with the Company, nor shall it 
interfere in any way with his or her right or the Company's right to 
terminate his or her employment or consulting relationship at any time, with 
or without cause.

    12. TAX CONSEQUENCES.  Optionee acknowledges that he or she has read the 
brief summary set forth below of certain federal tax consequences of exercise 
of this Option and disposition of the Shares under the law in effect as of 
the date of grant.  OPTIONEE UNDERSTANDS THAT THIS SUMMARY IS NECESSARILY 
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE 
SHOULD CONSULT HIS OR HER OWN TAX ADVISER BEFORE EXERCISING THIS OPTION OR 
DISPOSING OF THE SHARES.

        (a) EXERCISE OF NONSTATUTORY STOCK OPTION.  Optionee may incur 
regular federal income tax liability upon the exercise of the Option.  
Optionee will be treated as having received compensation income (taxable at 
ordinary income tax rates) equal to the excess, if any, of the fair market 
value of the Shares on the date of exercise over the Exercise Price.  In 
addition, if Optionee is an employee of the Company, the Company will be 
required to withhold from Optionee's compensation or collect from Optionee 
and pay to the applicable taxing authorities an amount equal to a percentage 
of this compensation income at the time of exercise.

        (b) DISPOSITION OF SHARES.  Gain realized on the disposition of 
Shares will be treated as long-term or short-term capital gain depending on 
whether or not the disposition occurs more than one year after the exercise 
date.

    13. SIGNATURE.  This Stock Option Agreement shall be deemed executed by 
the Company and Optionee upon execution by such parties of the Notice of Stock 
Option Grant attached to this Stock Option Agreement.
