                                     PART I
 
ITEM 1.  BUSINESS.
 
     This item contains 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 the factors set forth in "Certain
Additional Business Risks" below, the section of Item 7 -- Management's
Discussion and Analysis of Financial Condition and Results of Operations
entitled "Factors Affecting Future Results" and elsewhere in this Report.
 
     Document Sciences Corporation (the "Company") develops, markets and
supports a family of document automation software products and services used in
high volume electronic publishing applications. Document automation has become
increasingly important as more companies realize the benefits of automating the
high volume production of individually customized documents that require the
precise layout of information such as financial data, marketing text and graphs.
Autograph, the Company's document automation software architecture, enables
personalized and customized publishing solutions for many industries including
insurance, managed healthcare, financial services, telecommunications,
manufacturing/distribution, government and commercial print services. The
Company's products enable an important form of communication between
organizations and customers by employing enterprise database assets to produce
high-quality documents that are ready to print on demand and distribute in high
volume. Additionally, the Company's core technology is being applied to provide
electronic document automation solutions for the Internet, intranets and
commercial on-line services. CompuSet, Autograph's flagship product, is licensed
by approximately 500 customers worldwide who collectively produce an estimated
one billion customized pages per month. The fully portable Autograph platform
enables cost-effective, just-in-time, on-demand, high volume publishing that is
fully automated, capable of quality document composition, and flexible for
end-user customization. The Company's products are used in a wide array of
computing environments from client/server to large computer systems.
 
PRODUCTS
 
     The Company's software products are included in its Autograph architecture,
which currently addresses three major functional areas: Document Composition and
Assembly, Document Management, and Document Viewing, as described below. All of
the Company's software products can be complemented by Professional Services.
 
     The list price for an initial license fee for CompuSet, the Company's core
product, is currently $65,000 for an initial mainframe installation and ranges
down to $35,000 for an initial single PC; options currently range from $1,000 to
$50,000. The Company licenses its products for one year, after which an annual
renewal fee, usually in an amount equal to 15% of the initial license fee, is
required for continued use. A typical new sale is currently about $75,000 for
software licenses and approximately $25,000 for professional services.
 
     Document Composition and Assembly
 
     Composition and Assembly.  CompuSet, the Company's flagship product,
automates document composition and assembly using data and information in
corporate databases. It is the Company's core technology. CompuSet software
consists of a rule-based language and a composition engine that provide high
speed composition and assembly of complex documents with high typographic and
aesthetic levels of quality. Information content is marked with CompuSet tags
which, in turn, are defined in logically separate style specifications. Without
requiring real-time user interaction, the composition engine then transforms the
tagged data and information into finished electronic documents that can be
composed and assembled at rates in excess of 50 pages per second, depending on
computing configuration and complexity of the document. Document construction
facilities are extensive, including the full support of dynamic data driven
graphics generation. CompuSet operates on a range of computers and operating
systems including mainframes, workstations, network servers and personal
computers.
 
     Data Capture and Setup.  Data capture and setup products include CompuPrep
and a number of Importers, and prepare data and information for subsequent
composition and assembly by CompuSet.
 
                                        2
<PAGE>   3
 
CompuPrep is an optional tool that enables users to capture and tag raw data and
information from a variety of sources, including corporate databases, for
subsequent processing by CompuSet. It is a high level language that describes
the data environment, related data processing and the tagging instructions for
CompuSet. Importers accept externally generated document objects, including
text, static graphics and scanned images, and convert them into formats
compatible with CompuSet. The Importers support Adobe PostScript, Xerox Metacode
and TIFF standard for scanned images.
 
     Document Output and Merge.  Emitters transform CompuSet's output into a
number of popular Page Description Languages (PDLs) for printing and viewing.
The PDLs provide instructions for rendering text, forms, bitmaps, and graphics
into documents. The PDL formats currently supported are Xerox Metacode, IBM
AFPDS, Adobe PostScript, HP PCLV, Xerox Escape Sequences (XES), Xerox Interpress
(DocuTech) and generic line printers. This part of the architecture is
extensible and new Emitters can be provided as required. For example, the
Company expects to provide support for PDF from Adobe during 1997.
 
     Application Development Tools.  CompuSeries applications development tools
run on Microsoft Windows and simplify document design and application
prototyping. CompuSeries currently consists of several modules. CompuSpec is a
tool for defining document formatting rules. Formatting specifications which are
selected from a menu are associated with tags which are referenced in the
document data. The results of the selected formatting specifications are
visually displayed in a preview window. CompuBuild uses a PC version of
CompuSet, combined with an editor to manipulate the tagged document data.
CompuBuild supports all the dynamic functions and features of the CompuSet
production engine. CompuMerge is a tool used to specify the placement of
variable data into fixed document components such as in form-fill applications.
CompuView Proof is a document proofing tool used to preview the document layout
on the computer screen prior to printing. These tools were integrated into a
single Windows application, called CompuSeries II. Recently, the Company
announced it will OEM JetForm(R) Corporation's JetForm Design product as well as
the JetForm production print drivers for Metacode, DocuPrint and AFP printers,
and will integrate it with CompuSeries II.
 
     Document Management
 
     Document Management tools provide client/server solutions for the creation,
revision and management of document components used in the Company's document
automation solutions. They consist of the Document Library Service (DLS) and
Desktop Document Manager (DDM). DLS manages the document component creation
process required by complex variable documents. In addition, DLS can be used to
define complex assembly rules required for interactive or fully automated
document composition and assembly with CompuSet. DLS uses a client/server
architecture for accessing data and files on a mainframe or network server.
Desktop Document Manager (DDM) is the client component of DLS and manages text
objects created with Microsoft Word. Text objects are tracked and managed in a
multi-author environment by providing access security, revision control and
approval levels. DDM also provides a criteria-based document object selection
capability for customized or personalized documents. These criteria are then
used by DLS to generate a CompuSet-ready tagged data file. The customized or
personalized document assembly can be directed to occur in a high-volume fashion
on the server or in a just-in-time, on-demand fashion on the local DDM PC.
 
     Document Viewing
 
     Document Viewing enables on-line viewing and archiving of electronic
documents produced by document automation applications. It consists of the
Document Viewing Service (DVS) and CompuView. DVS uses a client/server
architecture for the creation and access of electronic document files. DVS is
available for a variety of mainframe, Unix and PC platforms. The electronic
document files are generated in a format called CCIF, which is optimized for
fast, memory-efficient viewing, transport and storage. CCIF files can then be
viewed by CompuView. CCIF files consist of three major components: a PDL
rendition of the pages for WYSIWYG viewing; various indices for locating
documents; and reusable document elements. CCIF files can also be distributed,
archived or printed through document distribution and archiving systems offered
by third party software developers that have integrated CompuView. CompuView is
a Windows application for viewing CCIF files. The view of the document is
virtually identical to the printed document. CompuView may
 
                                        3
<PAGE>   4
 
also be integrated with third party document retrieval systems. The Company
introduced the DVS in October 1995.
 
     The Company is considering possible future Internet extensions, some of
which are not currently under active development. The Company believes that its
core technology can be extended to the Internet, intranets and commercial online
services and has recently begun initial development activity in this area,
although there can be no assurance that such development activity will result in
commercially successful products. See "Business -- Research and Development."
 
PROFESSIONAL SERVICES
 
     In addition to its software products, the Company provides a comprehensive
suite of services which can assist customers in the implementation of enterprise
wide and mission critical document automation applications. Professional
Services include on-site software installation, customer training programs,
telephone support programs and consulting services. Consulting services are
currently focusing on assisting in the sale of high margin initial software
licenses by providing project management and application development.
Eventually, the Company intends to expand Professional Services to include
document design, systems design and integration. In addition to consulting
services, the Company currently offers introductory-level customer education,
which is bundled with CompuSet initial licenses. Additional and advanced classes
are provided for additional fees at the Company's headquarters in San Diego and
at customer sites. The Company offers advanced and specialized customer
education in response to the unique needs of certain customers. The Company
believes that expanded Professional Services enables customers to deploy the
Company's document automation products more rapidly and effectively, and assist
the Company in the development of new products and provide recurring revenue.
The Professional Services and support organizations employed a staff of 43 as of
December 31, 1996.
 
SALES AND MARKETING
 
     The Company's sales and marketing organization targets vertical industry
segments that require document automation and high volume document
personalization and customization. The Company currently licenses its products
using a combination of direct sales and alternate channels. In the United
States, the Company markets its products through a direct sales force. Sales
representatives are provided with pre-sales technical support by regional
application specialists. Sales representatives and the regional application
specialists are located in Atlanta, Chicago, Cleveland, Dallas, Minneapolis, New
York City, Pittsburgh, Richmond, Raleigh, Sacramento, Orange County, CA, San
Antonio, San Diego, San Francisco, Seattle and Washington, D.C. The Company
distributes its products through VAR relationships with Xerox Canada, Limited in
Canada and Fuji Xerox Co., Ltd. in Australia. The Company's subsidiary, Document
Sciences Europe, markets and supports the Company's products in Europe by
providing channel management, technical support, consulting and training
services, and defining European market and product requirements. The Company
licenses its products in Europe through VARs and, to a lesser extent, direct
sales. The VARs are principally Rank Xerox Ltd. and other Xerox affiliates who
remarket the Company's products. The Company's revenues from export transactions
with Xerox affiliates were $1.3 million, $3.1 million and $2.9 million in 1994,
1995 and 1996, respectively. The sales, marketing, consulting and customer
support organization employed a staff of 79 as of December 31, 1996.
 
     The Company intends to expand its sales and marketing organization to
provide direct sales and support services throughout the world. Such planned
expansion will occur by first addressing the unique product requirements of a
region followed by developing indirect sales channels to market in the region.
As the Company is able to increase its market presence, it may then augment its
alternate channels with a direct sales capability.
 
     In addition, the Company intends to increase both its product offerings and
markets through marketing, sales and distribution and development relationships
with other companies. Current relationships include formal and informal
marketing and sales alliances with Xerox, IBM, Siemens Nixdorf, Computer
Associates, New Dimension, RSD, Data/Ware Development, Data Retrieval and
JetForm Corporation. These relation-
 
                                        4
<PAGE>   5
 
ships provide sales leads for the Company's products and have extended the
Company's sales coverage and networking capabilities.
 
RESEARCH AND DEVELOPMENT
 
     In general, the Company's strategy is to build products that augment and
extend the document composition and assembly capabilities of its core products.
Initially, product development investments were primarily focused on completing
the Autograph architecture, which included delivering products for document
viewing as well as adding support for additional print environments. In
addition, there was a substantial investment in product maintenance and in
software integration, testing, and documentation. The Company supplements its
product development efforts by reviewing customer feedback on existing products
and working with customers and potential customers to anticipate future product
needs.
 
     To date, the Company's Autograph architecture has been applied mainly to
document automation applications producing paper based documents. The Company
believes that its core technology can be extended to provide document automation
for the Internet, intranets, and commercial on-line services. The short-term
strategy is to engage this emerging opportunity with two complementary
initiatives. First, the Company intends to work closely to define product
requirements with existing customers, many of whom have expressed interest in
using the Internet in their document automation solutions. Second, the Company
intends to develop incremental extensions to Autograph which can be incorporated
by current customers into existing document automation products provided by the
Company. The Company believes that its core technology can be extended to the
Internet, intranets and commercial on-line services, and has only recently begun
initial development activity in this area. There can be no assurance that the
Company will be successful in developing, introducing and marketing new products
on a timely and cost-effective basis, if at all, or that new products will
achieve market acceptance.
 
     The development organization is composed of self-directed teams, in which
representatives from various disciplines within the Company collectively take
responsibility for the development and delivery of each new feature or product.
The development process includes early review of prototypes and demonstrations
to incorporate customer feedback and provide an opportunity for management
review. A formal sequence of project phases organizes the development and review
process for each team. The Company has a formal release planning process for an
annual maintenance release, and delivers interim versions as needed to support
its customers. The development organization maintains a database of all customer
and internal requests which forms the basis for release planning.
 
     The Company expects to continue to enhance its existing products and to
develop new products, particularly as they relate to electronic publishing
applications. Research and development expenditures have grown substantially
since the Company's inception. Such expenditures were $1.0 million in 1994, $1.7
million in 1995 and $2.3 million in 1996. These amounts do not include product
support activities. The development organization has grown from 15 people in
1994, to 22 in 1995 and 32 in 1996. The Company employs independent contractors
as needed to supplement the permanent development staff.
 
COMPETITION
 
     The market for the Company's document automation products is intensely
competitive, subject to rapid change and significantly affected by new product
introductions and other market activities of industry participants. The
Company's software products are targeted at document intensive organizations
that require the ability to produce large quantities of customized and
personalized documents in paper or electronic form. The Company faces direct and
indirect competition from a broad range of competitors who offer a variety of
products and solutions to the Company's current and potential customers. The
Company's principal competition currently comes from (i) systems developed
in-house by the internal MIS departments of large organizations, (ii) direct
competition in a number of its vertical markets, including Image Sciences, which
is partially owned by Xerox, and FormMaker Software, Inc. in the insurance
industry, M&I Data Services, Inc. in banking and financial services and Group 1
Software, Inc. in commercial direct mailing, and (iii) direct competitors such
as IBM's Direct Composition Facility (DCF) and Group 1's recently introduced
DOC1
 
                                        5

product. The Company faces market resistance from the large installed base of
legacy systems because of the reluctance of these customers to commit the time
and effort necessary to convert their document automation processes to the
Company's document automation software. Several of the Company's competitors
have longer operating histories, significantly greater financial, technical,
marketing and other resources than the Company, greater name recognition and a
larger installed base of customers.
 
     It is also possible that the Company will face competition from new
competitors. These include large independent software companies offering
personal computer-based application software solutions, such as Microsoft
Corporation and Adobe Corporation, and from large corporations providing
database management software solutions, such as Oracle Corporation. In addition,
Xerox, either directly or through affiliated entities, could compete with the
Company. Moreover, as the market for document automation software develops, a
number of these or other companies with significantly greater resources than the
Company could attempt to enter or increase their presence in the Company's
market either independently or by acquiring or forming strategic alliances with
competitors of the Company or to otherwise increase their focus on the industry.
In addition, current and potential competitors have established or may establish
cooperative relationships among themselves or with third parties to increase the
ability of their products to address the needs of the Company's current and
prospective customers, and it is possible that new competitors or alliances
among competitors may emerge and rapidly acquire significant market share.
Increased competition may result in price reductions, reduced gross margins and
loss of market share, any of which could have a material adverse effect on the
Company's business, operating results and financial condition. There can be no
assurance that the Company will be able to compete successfully against current
or future competitors or that competitive pressures faced by the Company will
not materially adversely affect its business, operating results and financial
condition.
 
     The Company believes that the principal competitive factors affecting its
market include products performance and functionality, ease of use, scalability,
operation across multiple computer and operating system platforms, product and
company reputation, client service and support, and price. Although the Company
believes that it currently competes favorably with respect to such factors,
there can be no assurance that the Company will be able to maintain its
competitive position against current and future competitors or that the Company
will be successful in the face of increasing competition from new products or
solutions introduced by existing competitors or by new companies entering the
market. Further, there can be no assurance that the Company can maintain its
position against current and future competitors, especially those with greater
financial, marketing, service, support, technical and other resources than the
Company.
 
PATENTS AND PROPRIETARY RIGHTS
 
     The Company's success is dependent, in part, on its ability to protect its
proprietary technology. The Company relies primarily on a combination of
copyright and trademark laws, trade secrets, confidentiality procedures and
contractual provisions to protect its proprietary rights. The Company seeks to
protect its software, documentation and other written materials under trade
secret and copyright laws, which afford only limited protection. The Company
presently has no patents or patent applications pending. Despite the Company's
efforts to protect its proprietary rights, unauthorized parties may attempt to
copy aspects of the Company's products or to obtain and use information that the
Company regards as proprietary.
 
     Policing unauthorized use of the Company's products is difficult, and while
the Company is unable to determine the extent to which piracy of its software
products exists, software piracy can be expected to be a persistent problem. In
addition, the laws of some foreign countries do not protect the Company's
proprietary rights to as great an extent as do the laws of the United States.
There can be no assurance that the Company's means of protecting its proprietary
rights will be adequate or that the Company's competitors will not independently
develop similar technology. The Company is not aware that any of its products
infringes the proprietary rights of third parties. There can be no assurance,
however, that third parties will not claim infringement by the Company with
respect to current or future products. The Company expects that software product
developers will increasingly be subject to infringement claims as the number of
products and competitors in the Company's industry segment grows and the
functionality of products in different industry segments overlaps. Any such
claims, with or without merit, could be time consuming, result in costly
litigation, cause product shipment delays or require the Company to enter into
royalty or licensing agreements.
 
                                        6
<PAGE>   7
 
Such royalty or licensing agreements, if required, may not be available on terms
acceptable to the Company or at all, which could have a material adverse effect
upon the Company's business, operating results and financial condition.
 
     In addition, the Company also relies on certain software that it licenses
from third parties, including software that is integrated with internally
developed software and used in the Company's products to perform key functions.
There can be no assurances that such firms will remain in business, that they
will continue to support their products or that their products will otherwise
continue to be available to the Company on commercially reasonable terms. The
loss or inability to maintain any of these software licenses could result in
delays or reductions in product shipments until equivalent software can be
developed, identified, licensed and integrated, which would adversely affect the
Company's business, operating results and financial condition.
 
EMPLOYEES
 
     As of December 31, 1996 the Company had 126 employees including 79 in
sales, marketing, consulting and customer support, 32 in research and
development, and 15 in finance and administration. None of the Company's
employees is represented by a labor union. The Company has experienced no work
stoppages and believes its relationship with its employees is good. Competition
for qualified personnel in the industry in which the Company competes is
intensive. The Company believes that its future success will depend in part on
its continued ability to attract, hire, and retain qualified personnel.
 
CERTAIN ADDITIONAL BUSINESS RISKS
 
     The Company's business, financial condition and operating results may be
impacted by a number of factors, including but not limited to those set forth
below, any one of which could cause the Company's actual results to vary
materially from recent results or from the Company's anticipated future results.
 
     Limited Operating History.  The Company was incorporated in October 1991 as
a wholly-owned subsidiary of Xerox, and Xerox currently owns approximately 63%
of the Company's outstanding shares of Common Stock. The Company's limited
operating history makes the prediction of future operating results difficult,
and the Company's operating history during prior periods cannot necessarily be
regarded as indicative of the Company's prospects as an independent company,
especially in light of the Company's investments in sales, marketing,
professional services and development infrastructure. Accordingly, although the
Company has experienced revenue growth in recent years, there can be no
assurance that the Company will sustain such growth in revenues, if any, or that
the Company will remain profitable on a quarterly or annual basis.
 
     Uncertainty of Future Operating Results; Fluctuations in Quarterly
Operating Results.  The Company's total revenues and operating results can vary,
sometimes substantially, from quarter to quarter and are expected to vary
significantly in the future. The Company's revenues and operating results are
difficult to forecast. Future results will depend upon many factors, including
the demand for the Company's products, the level of product and price
competition, the length of the Company's sales cycle, the size and timing of
individual license transactions, the delay or deferral of customer
implementations, the budget cycles of the Company's customers, the level of
commissions on the sale of Xerox printers under the strategic marketing alliance
between the Company and Xerox, the Company's success in expanding its direct
sales force and indirect distribution channels, the timing of new product
introductions and product enhancements by the Company and its competitors, the
mix of products and services sold, levels of international sales, activities of
and acquisitions by competitors, the timing of new hires, changes in foreign
currency exchange rates, the ability of the Company to develop and market new
products and control costs and general domestic and international economic
conditions. In addition, the Company's sales generally reflect a relatively high
amount of revenues per order, and the loss or delay of individual orders,
therefore, could have a significant impact on the revenues and quarterly
operating results of the Company. Moreover, the timing of license revenue is
difficult to predict because of the length of the Company's sales cycle, which
is typically three to twelve months from the initial customer contact.
 
     The Company's initial software license products generally are shipped as
orders are received. As a result, initial license fee revenues are substantially
dependent on orders booked and shipped in that quarter. Because
 
                                        7
<PAGE>   8
 
the Company's operating expenses are based on anticipated revenue levels and
because a high percentage of the Company's expenses are relatively fixed, a
delay in the recognition of revenue from a limited number of license
transactions could cause significant variations in operating results from
quarter to quarter and could result in losses. To the extent such expenses
precede increased revenues, the Company's operating results would be materially
adversely affected.
 
     The Company's business has experienced and is expected to continue to
experience seasonality, in part due to customer purchasing patterns and the
Company's expense patterns. The Company believes that fourth quarter revenues
are positively impacted by year-end capital purchases by large corporate
customers and strong fourth quarter sales of printers by Xerox (which may
generate sales of the Company's products), as well as the Company's sales
compensation plans. As reflected in the fourth quarter of 1996, these seasonal
factors have historically resulted in fourth quarter revenues being
substantially higher than revenues in the preceding three quarters, as well as
being higher than revenues in each of the first two quarters of the next year.
In addition, a significant amount of the Company's revenues occur predominantly
in the third month of each fiscal quarter and tend to be concentrated in the
latter half of the third month.
 
     As a result of these factors, revenues for any quarter are subject to
significant variation, and the Company believes that period-to-period
comparisons of its results of operations are not necessarily meaningful and
should not be relied upon as indications of future performance. Furthermore, due
to all of the foregoing factors, it is likely that in some future quarter the
Company's operating results will be below the expectations of public market
analysts and investors. In such event, the price of the Company's Common Stock
would likely be materially adversely affected. See "Expansion of Sales and
Distribution Channels" below, and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     Control by Xerox.  Xerox owns approximately 63% of the outstanding shares
of Common Stock of the Company. Xerox has not expressed to the Company any
present intention to sell additional shares of the Company's Common Stock
following completion of the offering. Consequently, Xerox will control the
Company, be able to elect the entire Board of Directors of the Company and
continue to have significant input into the Company's operations. In addition,
Xerox will be able to determine the outcome of all corporate actions requiring
stockholder approval, including potential mergers, acquisitions, consolidations
and sales of all or substantially all of the assets of the Company. The voting
power of Xerox could have the effect of delaying or preventing a change in
control of the Company, and may prevent or discourage tender offers for the
Company's Common Stock at a premium price by another person or entity. At
present, Xerox affiliates hold three of the six seats on the Company's Board of
Directors. See "Reliance on Relationships with Xerox; Lack of Independent Sales
and Marketing Channels" below.
 
     Reliance on Relationships with Xerox; Lack of Independent Sales and
Marketing Channels.  The Company currently has a variety of contractual and
informal relationships with Xerox and affiliates of Xerox, including a Strategic
Marketing Alliance Agreement, a Transfer and License Agreement and various
distribution agreements. The Company relies on these relationships and
agreements for a significant portion of its total revenues. In 1994, 1995 and
1996, total revenues derived from relationships with Xerox and affiliates of
Xerox accounted for approximately $1.9 million, $3.9 million and $4.2 million,
representing 27%, 37% and 28% of the Company's total revenues, respectively. In
addition, through December 31, 1995 substantially all of the Company's domestic
license revenues were dependent on sales leads generated as a result of the
Company's relationship with Xerox and a substantial portion of the Company's
international revenues were made through distributors and distribution channels
affiliated with Xerox. Further, the commissions received by the Company from
sales of Xerox printers under the strategic marketing alliance, which were
$490,400, $752,000 and $1.4 million in 1994, 1995 and 1996, respectively, have
little or no associated costs, have contributed a substantial portion of the
Company's income from operations and net income for certain prior operating
periods, have had a high degree of inconsistency from quarter to quarter and are
difficult to estimate. Failure to continue to receive such commissions would
have a material adverse effect on the Company's business, operating results and
financial condition. Although neither Xerox nor its affiliated entities has
expressed to the Company any intention to terminate their respective agreements
with the Company, these agreements generally may be terminated on no more than
90 days' notice. Accordingly, there can be no assurance that Xerox or its
affiliates will continue these relationships or, if they do, that they will be
on terms
 
                                        8
<PAGE>   9
 
favorable to the Company. Furthermore, there can be no assurance that existing
and potential customers will not be deterred by the existence of these
relationships or by the historical ties between the Company and Xerox and its
affiliates. Though the Company intends to continue its existing relationships
with Xerox, the Company's strategy is to lessen its dependence on Xerox.
However, there can be no assurance that the Company will be able to do so and,
because of the Company's current level of dependence on Xerox, there can be no
assurance that the Company's transition to a more independent company will not
adversely affect its business, financial condition or results of operations. The
failure by the Company to maintain these relationships, particularly with Xerox
and its affiliates, or to establish new relationships in the future, could have
a material adverse effect on the Company's business, operating results and
financial condition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations," and "Expansion of Sales and Distribution
Channels" below.
 
     Xerox has strategic alliances and other business relationships with other
companies who supply software and services used in high volume electronic
publishing applications and who now or in the future may be a competitor of the
Company. Xerox could in the future expand these relationships or enter into
additional ones, and as a result the Company's business could be materially
adversely affected. There can be no assurance that Xerox or one of its
affiliated companies will not engage in business directly competitive with the
Company. In addition, Xerox has on-going internal development activities which
could in the future lead to products that compete with the Company.
 
     Expansion of Sales and Distribution Channels.  The Company has
substantially increased expenditures in support of its strategy to expand its
global marketing, sales and customer support infrastructure in order to expand
the market for the Company's products by providing direct sales and support
services and increased channel distribution throughout the major markets of the
world. Through this expansion, the Company hopes to lessen its dependence on
Xerox and certain Xerox affiliates. In addition, the Company intends to increase
both its product offerings and markets through marketing, sales and distribution
and development relationships with other companies. The Company intends to
increase the number of these strategic relationships as well as form alliances
with system integrators and consultants. Whether the Company can successfully
generate its own sales leads, introduce new products and enter into new markets
will depend on its ability to expand its direct sales and support services,
expand its indirect channel distribution, and increase its relationships and
alliances with other companies. As a result of its planned expansion, the
Company has and will continue to incur significant costs to build such corporate
infrastructure ahead of anticipated revenues, and any failure to achieve growth
in revenues in excess of increased expenses would have a material adverse affect
on the Company's business, operating results and financial condition. There can
be no assurance that the Company will be able to successfully expand its direct
sales and support services force, expand its indirect channel distribution, or
establish or maintain successful third party relationships. Any failure to do so
will have a material adverse effect on the Company's business, operating results
and financial condition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
     Dependence on Success of New Products and Expansion of Professional
Services.  The Company's Autograph architecture has been applied mainly to
document automation applications producing paper based documents. The Company
believes its core technology can be extended to address applications requiring
the delivery of customized and personalized electronic documents over electronic
networks such as the Internet, intranets or commercial on-line services.
 
     The Company began shipping Document Viewing Service (DVS), an optional
on-line viewer for electronic documents produced by document automation
application in October 1995. Document Library Services (DLS), an optional
document management tool, was released for general availability in September
1996. Prior to September 1996, DLS was in a limited release, with certain
configurations still in beta testing. Revenues for DVS were $1.26 million in
1996. Revenues for DLS were $1.0 million in 1996. Revenues for DVS and DLS were
insignificant in 1995.
 
     In addition, the Company is increasing its focus on the consulting services
component of its Professional Services to assist customers in the planning and
implementation of enterprise-wide, mission critical document automation
applications. The Company has directed a significant amount of its product
development
 
                                        9
<PAGE>   10
 
expenditures to the on-going development of DVS and DLS and plans to devote a
significant amount of future sales and marketing resources to the full
commercial introduction of DVS and DLS.
 
     The Company believes that the long-term growth of license and service
revenue will be dependent, in part, upon the success of DVS, DLS and the
expansion of Professional Services. The Company has limited experience in
developing new products. Because of such limited experience, there can be no
assurance that DVS and DLS will not require substantial software enhancements or
modifications to satisfy performance requirements of clients or to correct
design defects. Further, there can be no assurance that the Company will be
successful in expanding its consulting services as part of its Professional
Services. If clients experience significant problems with implementation of the
software or are otherwise dissatisfied with the functionality or performance of
DVS and DLS, or if DVS or DLS fails to achieve market acceptance for any reason,
or if the Company fails to successfully expand its Professional Services, the
Company's business, operating results and financial condition will be materially
adversely affected.
 
     Lengthy Sales and Implementation Cycles.  The license of the Company's
software products is often an enterprise-wide decision by prospective customers
and generally requires the Company to engage in a lengthy sales cycle, typically
between three and twelve months, to provide a significant level of education to
prospective customers regarding the use and benefits of the Company's products.
In addition, the implementation of the Company's products by customers involves
a significant commitment of resources by such customers over an extended period
of time, and is commonly associated with substantial customer business process
reengineering efforts. For these and other reasons, the sales and customer
implementation cycles are subject to a number of significant delays over which
the Company has little or no control. Delay in the sale or customer
implementation of a limited number of license transactions could have a material
adverse effect on the Company's business and results of operations and cause the
Company's operating results to vary significantly from quarter to quarter. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
     Product Concentration.  The Company derived 73.9% of its initial license
revenues from licenses of CompuSet and related CompuSet option products in 1996.
Initial license fees from DVS and DLS comprised 14.7% and 11.4%, respectively,
in 1996. As a result, factors adversely affecting the pricing of or demand for
CompuSet and related products, such as competition from other products, negative
publicity or obsolesce of the hardware or software environments in which the
Company's products run, could have a material adverse effect on the Company's
business, operating results and financial condition. The Company's financial
performance will continue to depend, in significant part, on the successful
development, introduction and customer acceptance of new and enhanced versions
of the CompuSet software and related products. There can be no assurance that
the Company will continue to be successful in developing and marketing CompuSet
products and related services. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     Industry Concentration.  Licenses to end users in the insurance and
commercial print services industries for 1994, 1995 and 1996 accounted for 65%,
61% and 55%, respectively, of total revenues. The future success of the Company
will depend on its ability to continue to successfully market its products in
such industries, and to successfully market its products in other industries.
The failure of the Company to do so would have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
     Dependence on New Products and Product Enhancements.  The Company's future
business, operating results and financial condition will continue to depend upon
its ability to develop new products that address the future needs of its target
markets and to respond to emerging industry standards and practices. The Company
believes that its core technology can be extended to the Internet, intranets and
commercial on-line services, and has only recently begun initial development
activity in this area. There can be no assurance that the Company will be
successful in developing, introducing and marketing new products or product
enhancements, including new products or the extension of existing products for
the Internet, intranets and commercial on-line services, on a timely and cost
effective basis, if at all, or that its new products and product enhancements
will adequately meet the requirements of the marketplace or achieve market
acceptance. Delays in the
 
                                       10
<PAGE>   11
 
commencement of commercial shipments of new products or enhancements, including
DVS and DLS, may result in client dissatisfaction and delay or loss of product
revenues. If the Company is unable, for technological or other reasons, to
develop and introduce new products or enhancements of existing products in a
timely manner in response to changing market conditions or client requirements,
or if new products or new versions of existing products do not achieve market
acceptance, the Company's business, operating results and financial condition
will be materially adversely affected. In order to provide its customers with
integrated product solutions, the Company's future success will also depend in
part upon its ability to maintain and enhance relationships with its technology
partners, such as Computer Associates and Data Retrieval. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
     International Operations.  Revenues from export sales, including sales
through its foreign subsidiary accounted for 26%, 42% and 34% of the Company's
total revenues in 1994, 1995 and 1996, respectively. The Company's wholly owned
subsidiary, Document Sciences Europe, markets and supports the Company's
products in Europe. The Company licenses its products in Europe through value
added resellers and to a lesser extent, direct sales. The value added resellers
are principally Xerox affiliates who re-market the Company's products. In
Australia and Canada, the Company distributes its products through Fuji Xerox
Co., Ltd. and Xerox Canada, Limited, respectively. Revenues generated by these
Xerox affiliates were $1.3 million, $3.1 million and $2.9 million in 1994, 1995
and the 1996, respectively. In 1994 and 1995, a substantial portion of the
Company's revenues from export sales were generated through entities affiliated
with Xerox. In order to successfully expand export sales, the Company must
establish additional foreign operations, hire additional personnel and develop
relationships with additional international resellers. To the extent that the
Company is unable to do so in a timely manner, the Company's growth, if any, in
international export sales will be limited, and the Company's business,
operating results and financial condition could be materially adversely
affected. In addition, there can be no assurance that the Company will be able
to maintain or increase international market demand for its products. Additional
risks inherent in the Company's international business activities generally
include currency fluctuations, unexpected changes in regulatory requirements,
tariffs and other trade barriers, costs of and the Company's limited experience
in localizing products for foreign countries, lack of acceptance of localized
products in foreign countries, longer accounts receivable payment cycles,
difficulties in managing international operations, potentially adverse tax
consequences including restrictions on the repatriation of earnings, and the
burdens of complying with a wide variety of foreign laws. A portion of the
Company's business is conducted in currencies other than the U.S. dollar,
primarily the French franc. Although to date exchange rate fluctuations have not
had a significant impact on the Company, fluctuations in the value of the
currencies in which the Company conducts its business relative to the U.S.
dollar could cause currency transaction gains and losses in future periods. The
Company does not currently engage in currency hedging transactions, and there
can be no assurance that fluctuations in the currency exchange rates in the
future will not have a material adverse impact on international revenues and
thus the Company's business, operating results or financial condition. There can
be no assurance that such factors will not have a material adverse effect on the
Company's future international operations and, consequently, the Company's
results of operations. See "Control by Xerox" above and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
     Dependence on Emerging Markets for Document Automation Software.  The
market for document automation software is relatively new, intensely
competitive, highly fragmented, underdeveloped and subject to rapid change.
Marketing and sales techniques in the document automation software marketplace,
as well as the bases for competition, are not well established. There can be no
assurance that the market for document automation software will develop or that,
if it does develop, organizations will adopt the Company's products. The Company
has spent, and intends to continue to spend, significant resources educating
potential customers about the benefits of its products. However, there can be no
assurance that such expenditures will enable the Company's products to achieve
further market acceptance, and if the document automation software market fails
to develop or develops more slowly than the Company currently anticipates, the
Company's business, operating results and financial condition would be
materially adversely affected. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
                                       11
<PAGE>   12
 
     In addition, the commercial market for document automation of electronic
documents designed for use with the Internet, intranets and commercial on-line
services has only recently begun to develop, and the success of the Company's
products designed for this market will depend, in part, on their compatibility
with such services. It is difficult to predict with any assurance whether the
Internet, intranets and commercial on-line services will prove to be a viable
commercial marketplace or whether the demand for related products and services
will increase or decrease in the future. Since the increased commercial use of
the Internet, intranets and commercial on-line services could require
substantial modification and customization of certain of the Company's products
and services and the introduction of new products and services, there can be no
assurance that the Company will be able to effectively or successfully compete
in this emerging market.
 
     Management of Change; Dependence Upon Key Personnel.  The Company has
recently experienced a period of growth in total revenues. The Company's ability
to compete effectively and to manage future change will require the Company to
continue to improve its financial and management controls, reporting systems and
procedures on a timely basis and to expand, train and manage its employee work
force. There can be no assurance that the Company will be able to do so
successfully. The Company's failure to do so could have a material adverse
effect on the Company's business, operating results and financial condition. The
Company's future performance depends in significant part upon the continued
service of its key technical, sales and senior management personnel, none of
whom are parties to employment agreements with the Company. The loss of the
services of one or more of the Company's executive officers could have a
material adverse effect on the Company's business, operating results and
financial condition. The Company's future success also depends on its continuing
ability to attract and retain highly-qualified product development, sales and
managerial personnel. Competition for such personnel is intense, and there can
be no assurance that the Company will be able to retain its key employees or
that it will be able to attract, assimilate or retain other highly qualified
product development, sales and managerial personnel in the future. See "Control
by Xerox" above.
 
     Product Liability.  The Company's license agreements with its customers
typically contain provisions designed to limit the Company's exposure to
potential product liability claims. However, it is possible that the limitation
of liability provisions contained in the Company's license agreements may not be
effective under the laws of certain jurisdictions. Although the Company has not
experienced any product liability claims to date, the sale and support of
products by the Company may entail the risk of such claims, and there can be no
assurance that the Company will not be subject to such claims in the future. A
successful product liability claim or claim arising as a result of professional
services rendered by the Company brought against the Company could have a
material adverse effect upon the Company's business, operating results and
financial condition.
 
     Risk of Product Defects.  Software products as complex as those offered by
the Company, particularly the Company's new DVS and DLS products, may contain
undetected defects or errors when first introduced or as new versions are
released. As a result, the Company could in the future lose or delay recognition
of revenues as a result of software errors or defects. In addition, the
Company's products are typically intended for use in applications that may be
critical to a customer's business. As a result, the Company expects that its
customers and potential customers have a greater sensitivity to product defects
than the market for software products generally. Although the Company's business
has not been adversely affected by any such errors to date, there can be no
assurance that, despite testing by the Company and by current and potential
customers, errors will not be found in new products or releases after
commencement of commercial shipments, resulting in loss of revenue or delay in
market acceptance, diversion of development resources, damage to the Company's
reputation, or increased service and warranty costs, any of which would have a
material adverse effect upon the Company's business, operating results and
financial condition.
 
ITEM 2.  PROPERTIES.
 
     The Company's principal administrative, sales, marketing, training, and
research and development facilities occupy approximately 15,000 square feet in

OVERVIEW
 
     Document Sciences Corporation develops, markets and supports a family of
document automation software and services used in high volume electronic
publishing applications. The Company was incorporated in Delaware in October
1991 as a wholly-owned subsidiary of Xerox Corporation ("Xerox"), and following
the Company's initial public offering of stock in September 1996, Xerox
ownership was reduced to approximately 63%.
 
INITIAL PUBLIC OFFERING
 
     In September 1996, the Company completed an initial public offering ("IPO")
in which 2,645,000 shares of its Common Stock were sold, including 462,500
shares which were sold by certain selling stockholders, at $12.00 per share. The
IPO generated net proceeds to the Company of approximately $23.33 million.

RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
 
     Revenues
 
     Total revenues were $15.3 million, $10.5 million and $7.2 million in 1996,
1995 and 1994, respectively, representing increases of 46% from 1995 to 1996 and
47% from 1994 to 1995. The Company's revenues are divided into three categories
based upon the sources from which they are derived: initial license fees, annual
renewal license and support fees, and services and other revenues. Initial
license fees are comprised principally of license fees for the first year of use
of the Company's products by end user customers. Annual renewal license and
support fees are comprised principally of mandatory fees paid by customers
annually for continued use and support of the licensed products. Services and
other revenues are comprised principally of fees for consulting, application
development and training services performed by the Company as well as fees
received from Xerox in connection with the sale of certain Xerox printer
products. The Company recognizes revenue in accordance with AICPA Statement of
Position on Software Revenue Recognition No. 91-1. Initial license revenue is
recognized upon shipment of the product to customers if no significant Company
obligations remain and collection of the receivable is deemed probable. The
portion of the initial license revenue which represents the software support for
the first year is deferred and recognized ratably over the contract period.
Revenues from commissions paid by Xerox in connection with the sale of Xerox
printer products are recognized upon installation of the printer products.
Revenues generated from consulting and training services are recognized as the
related services are performed.
 
     The growth of total revenue in each year was due primarily to increased
numbers of initial software license customers and growth in services and other
revenue, and to the expansion of the Company's sales force and product
consultants.
 
     The Company sells its products principally through a direct sales force
domestically, and internationally principally through distributors and value
added resellers ("VARS") and, to a lesser extent, through its direct sales
force. Revenues from export sales and sales through the Company's foreign
subsidiary were $5.2 million, $4.4 million and $1.9 million in 1996, 1995 and
1994, respectively, representing increases of 18% from 1995 to 1996 and 132%
from 1994 to 1995. The growth in export sales from 1994 to 1995 was due
primarily to expansion of the value added reseller channel in Europe. The growth
in export sales from 1995 to 1996 was the result of new customers licensing the
Company's products. Revenue from export sales were 34%, 42% and 26% of total
revenue for the 1996, 1995 and 1994, respectively. The increase in export sales
as a percentage of total revenue in 1995 relative to 1994 was the result of
establishing a subsidiary in Europe to focus on serving the European market. In
1996, export revenue declined as a percentage of total revenue principally
because of reduced sales in Australia and Canada.
 
     The Company and Xerox maintain a strategic marketing alliance agreement
under which the parties have agreed to pay each other fees on referrals that
lead to the successful licensing or sales of each other's products. The
Company's revenues from the strategic marketing alliance, principally
commissions from sales of Xerox printers, were $1.4 million, $752,000 and
$490,400 for 1996, 1995 and 1994, respectively. These commissions were 9% of
total revenue in 1996 and 7% of total revenue in 1995 and 1994. Failure to
continue to receive such commissions would have a material adverse effect on the
Company's business, operating results and financial condition.
 
     The Company has entered into distributorship agreements with various Xerox
foreign affiliates to remarket the Company's products internationally. The
Company's revenues from such distributorship agreements relating to the
licensing, maintenance and support of the Company's products were $2.9 million,
$3.1 million and $1.3 million in 1996, 1995 and 1994, respectively. The decrease
in revenues from Xerox foreign affiliates in 1996 relative to 1995 was the
result of reduced sales by affiliates in Australia and Canada. Revenues from
affiliates in Europe increased 3% from 1996 to 1995.
 
     Initial license fees.  Initial license fee revenues were $8.6 million, $6.3
million and $4.4 million in 1996, 1995 and 1994, respectively, representing
increases of 36% from 1995 to 1996 and 42% from 1994 to 1995. Initial license
revenues as a percentage of total revenue were 56%, 60% and 62%, in 1996, 1995
and 1994, respectively. The growth in initial license revenues in each period
was attributable to increases in both the size
 
                                       15
<PAGE>   16
 
of licensing transactions and the number of new customers. To a lesser extent,
growth in 1996 was the result of introduction of the Company's new products,
Document Viewing Services and Document Library Services.
 
     Annual renewal license and support fees.  Revenues from annual renewal
licenses were $2.4 million, $1.9 million and $1.5 million for 1996, 1995 and
1994, respectively, representing increases of 25% from 1995 to 1996 and 28% from
1994 to 1995. The increase in both periods was principally due to the increase
in the installed base of users of the Company's software products. As a
percentage of total revenue, annual renewal license and support fees were 16%,
18% and 21% in 1996, 1995 and 1994, respectively. The decrease of annual renewal
license and support fees as a percentage of total revenue resulted from the
greater rate of increase in revenue derived from initial license fees and
services and other.
 
     Services and other.  Revenues from services and other were $4.3 million,
$2.3 million and $1.2 million in 1996, 1995 and 1994, respectively, representing
increases of 90% from 1995 to 1996 and 86% from 1994 to 1995. The increase in
each period was principally due to the increased number of new customer licenses
of the Company's software generating increased demand for services as well as
the increasing scope of professional services offered, and the increase in
commissions from $752,000 to $1.4 million from 1995 to 1996 and $490,400 to
$752,000 from 1994 to 1995, respectively, under the strategic marketing alliance
for the sale of Xerox printer products. Revenues from services and other were
28%, 22% and 17% of total revenues in 1996, 1995 and 1994, respectively.
 
     Cost of Revenues
 
     Cost of initial license fees.  Cost of initial license revenues were
$696,000, $351,000 and $274,000 in 1996, 1995 and 1994, respectively,
representing 8%, 6% and 6% of initial license revenues in 1996, 1995 and 1994,
respectively. Cost of initial licenses of software includes documentation,
reproduction costs, product packaging, packaging design, product media,
employment costs for training, installation and distribution personnel, the cost
of third party software and amortization of previously capitalized software
development costs. The increase of cost of initial licenses as a percentage of
initial license revenues was primarily the result of increased payments for
third party software integrated into the Company's Document Library software
products.
 
     Cost of annual licenses renewals.  Cost of annual licenses renewals
consists principally of the employment-related costs for the Company's technical
support staff, which performs technical software support services. Cost of
annual licenses renewal revenues was $497,000, $370,000 and $267,000 in 1996,
1995 and 1994, respectively, representing 21%, 19% and 18% of annual licenses
renewal revenues. These costs increased as a result of the increases in
personnel to support the expansion of the installed base of users of the
Company's software products and the increased product offerings of the Company.
 
     Cost of services and other.  Cost of services and other revenues were $1.1
million, $424,000 and $192,000 in 1996, 1995 and 1994, respectively,
representing 25%, 19% and 16% of services and other revenue. Cost of services
and other consists principally of the employment-related costs for the Company's
staff of product consultants and trainers. There are little or no costs related
to commissions from the sale of Xerox printers under the strategic marketing
alliance. The increase in cost of services and other revenues resulted
principally from the additional staffing to perform the Company's professional
services.
 
     Research and development.  Research and development expenses were $2.3
million, $1.7 million and $1 million in 1996, 1995 and 1994, respectively,
representing increases of 34% from 1995 to 1996 and 67% from 1994 to 1995.
Research and development expenses consist primarily of the employment-related
costs of personnel associated with developing new products, enhancing existing
products, testing software products and developing product documentation. As a
percentage of total revenue, research and development expenses were 15%, 17% and
15% in 1996, 1995 and 1994 respectively. The Company anticipates that it will
continue to direct significant resources to development and enhancement of
products.
 
     The Company expenses all costs for research and development of new products
until technological feasibility has been assured. Thereafter, costs of
production are capitalized until general release of the product. The capitalized
costs of software production are amortized using the greater of the amount
computed using
 
                                       16
<PAGE>   17
 
the ratio of current product revenues to estimated total product revenues or the
straight-line method over the remaining estimated economic lives of the
products. The Company capitalized software development expenses of $104,000,
$291,000 and $164,000 in 1996, 1995 and 1994, respectively. The increase in
capitalized software development expenses in 1995 compared to 1994, and
subsequent reduction from 1995 compared to 1996 was the result of the Company's
development of the Document Viewing Services product during 1995.
 
     Selling, and marketing.  Selling and marketing expenses were $7.4 million,
$4.4 million and $2.8 million in 1996, 1995 and 1994, respectively, representing
increases of 67% from 1995 to 1996 and 60% from 1994 to 1995. Selling and
marketing expenses consist primarily of salaries, commissions, marketing
programs and related costs for pre- and post-sales activity. The increase for
both periods was the result of adding personnel to increase geographic coverage
of the selling organization and, to a lesser extent, the higher commissions
associated with increased revenues. The increase in 1995 compared to 1996 was
also the result of adding employees to develop and deliver the professional
services. Selling and marketing expenses were 48%, 42% and 39% of total revenues
in 1996, 1995 and 1994, respectively.
 
     General and administrative.  General and administrative expenses consist of
employment-related costs for finance, administration and human resources, and
general corporate management and services. General and administrative expenses
were $1.7 million in 1996, $1.5 million in 1995 and $1.3 million in 1994
representing 11%, 14% and 18% of total revenue in 1996, 1995 and 1994,
respectively. The increase in general and administrative expenses in absolute
dollars was the result of growth in the finance and administrative operations to
support the growth of the Company. The decrease of these expenses as a
percentage of total revenues reflects the benefits of economies of scale.
 
     Interest income (expense), net.  Interest income (expense) is primarily
composed of interest income from cash and cash equivalents and short term
investments offset by financing charges related to equipment leases and other
debt. Interest income (expense), net was $318,000, $5,000 and $(9,000) in 1996,
1995 and 1994, respectively. The increase in dollar amount is primarily due to
higher cash balances resulting from the infusion of cash from the Company's
initial public offering of common stock completed in September 1996.
 
     Provision for income taxes.  Effective tax rates were approximately 31%,
38% and 47% in 1996, 1995 and 1994, respectively. These rates differ from the
federal statutory rate primarily due to recognition of a net operating loss
carryforward from the Company's foreign subsidiary. From its inception to
September 19, 1996, the Company's taxes were included in the consolidated tax
returns of Xerox Corporation. For reporting purposes, the Company recognized
income tax expense on pretax income at the tax rates in effect as if the Company
were filing tax returns on a stand-alone basis.
 
FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS
 
     The Company's total revenues and operating results can vary, sometimes
substantially, from quarter to quarter and are expected to vary significantly in
the future. The Company's revenues and operating results are difficult to
forecast. Future results will depend upon many factors, including the demand for
the Company's products, the level of product and price competition, the length
of the Company's sales cycle, the size and timing of individual license
transactions, the delay or deferral of customer implementations, the budget
cycles of the Company's customers, the Company's success in expanding its direct
sales force and indirect distribution channels, the timing of new product
introductions and product enhancements by the Company and its competitors, the
mix of products and services sold, levels of international sales, activities of
and acquisitions by competitors, the timing of new hires, changes in foreign
currency exchange rates, the ability of the Company to develop and market new
products and control costs, and general domestic and international economic
conditions. In addition, the Company's sales generally reflect a relatively high
amount of revenues per order, and, therefore, the loss or delay of individual
orders could have a significant impact on revenues and quarterly operating
results of the Company. In addition, a significant amount of the Company's
revenues occur predominantly in the third month of each fiscal quarter and tend
to be concentrated in the latter half of that third month.
 
     The Company's software products generally are shipped as orders are
received. As a result, initial license revenues in any quarter are substantially
dependent on orders booked and shipped in that quarter. The timing
 
                                       17
<PAGE>   18
 
of receipt of initial license revenue is difficult to predict because of the
length of the Company's sales cycle, which is typically three to twelve months
from the initial contact. Because the Company's operating expenses are based on
anticipated revenue trends and because a high percentage of the Company's
expenses are relatively fixed, a delay in the recognition of revenue from a
limited number of initial license transactions could cause significant
variations in operating results from quarter to quarter and could result in
losses. To the extent such expenses precede, or are not subsequently followed
by, increased revenues, the Company's operating results would be materially
adversely affected.
 
     Due to the foregoing factors, revenues and operating results for any
quarter are subject to significant variation, and the Company believes that
period-to-period comparisons of its results of operations are not necessarily
meaningful and should not be relied upon as indications of future performance.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In September 1996, the Company completed its IPO and received net proceeds
of approximately $23.33 million.
 
     At December 31, 1996, the Company had $25.6 million in cash, cash
equivalents and short-term investments. The Company has an agreement with a bank
that provides a working capital line of credit at the bank's prime rate. The
agreement, which expires in July 1997, allows maximum borrowings of the lesser
of $2.5 million or 75% of eligible accounts receivable. At December 31, 1996,
the Company had no outstanding borrowings under this agreement.
 
     Net cash provided by operating activities was $1.7 million, $1.2 million
and $1.3 million in 1996, 1995 and 1994, respectively. Net cash used in
investing activities was $23.8 million, $589,000 and $411,000 in 1996, 1995 and
1994, respectively. In 1996, net cash used in investing activities was primarily
used for purchase of short term investments and to a lesser extent, for the
purchase of fixed assets. In 1995 and 1994, net cash used in investing
activities was primarily used for the purchase of fixed assets. Net cash
provided by financing activities in 1996 was $23.3 million, primarily from net
proceeds from the initial public offering of the Company's common stock. In 1995
net cash provided by financing activities was $27,000, primarily from issuance
of the Company's common stock pursuant to exercise of options granted under the
Employee Stock Option Plan, offset by payments of capital lease obligations. Net
cash used for financing activities in 1994 was primarily for repayment of bank
notes.
 
     With the exception of plans to undertake capital spending to expand the
corporate facilities in the first quarter of 1997, the Company has no
significant capital spending or purchase commitments other than normal purchase
commitments and commitments under facilities and capital leases.
 
     The Company believes that its existing cash balances and anticipated cash
flows from operations will be sufficient to meet its anticipated cash needs for
working capital and capital expenditures at least through the next twelve
months. A portion of the Company's cash could be used to acquire or invest in
complementary businesses or products or obtain the right to use complementary
technologies. The Company is currently evaluating, in its ordinary course of
business, potential investments such as businesses, products or technologies.
The Company has no current understandings, commitments or agreements with
respect to any acquisition of other businesses, products or technologies.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Document Sciences Corporation
 
     We have audited the accompanying consolidated balance sheets of Document
Sciences Corporation as of December 31, 1995 and 1996, and the related
consolidated statements of income, redeemable preferred stock and stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Document
Sciences Corporation at December 31, 1995 and 1996, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1996, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION
 
     Document Sciences Corporation (the "Company") was incorporated on October
18, 1991 in Delaware as a subsidiary of Xerox Corporation ("Xerox"). The Company
develops, markets and supports a family of document automation software products
and services used in high volume electronic publishing applications. Autograph,
the Company's document automation software architecture, enables personalized
publishing solutions for many industries including insurance, managed
healthcare, financial services, telecommunications, government agencies and
commercial print service bureaus.
 
     The Company currently derives substantially all of its license revenues
from licenses of CompuSet, Autograph's flagship product, and related products
and from fees for services related to the CompuSet software. The Company's
financial performance will continue to depend, in significant part, on the
successful development, introduction and customer acceptance of new and enhanced
versions of the CompuSet software and related products. There can be no
assurance that the Company will continue to be successful in developing and
marketing CompuSet products and related services.
 
     The Company currently has a variety of contractual and informal
relationships with Xerox and affiliates of Xerox, including a strategic
marketing alliance agreement, a transfer and license agreement and various
distribution agreements. There can be no assurance that Xerox or its affiliates
will continue these relationships. The failure by the Company to maintain these
relationships with Xerox and its affiliates could have a material adverse effect
on the Company's financial statements.
 
BASIS OF PRESENTATION
 
     In 1994, the Company established a wholly-owned subsidiary, Document
Sciences Europe, in Sophia Antipolis, France in order to market and support its
products to the European community. The accompanying consolidated financial
statements include the accounts of the Company and its subsidiary. Significant
intercompany accounts and transactions have been eliminated in consolidation.
 
USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
FOREIGN OPERATIONS
 
     The functional currency of the Company's France subsidiary is the French
Franc. The balance sheet accounts of the subsidiary are translated into United
States dollars at exchange rates prevailing at the balance sheet dates. Revenues
and expenses are translated into U.S. dollars at the average rates of exchange
during the period. Net realized translation adjustments were insignificant in
1994, 1995 and 1996. Foreign currency transaction gains and losses are included
in the consolidated statements of income and were not material during the years
ended December 31, 1994, 1995 and 1996.
 
CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
     Cash and cash equivalents consist of cash and highly liquid investments
which include debt securities with remaining maturities when acquired of three
months or less and are stated at market. The Company
 
                                       F-6

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
evaluates the financial strength of institutions at which significant
investments are made and believes the related credit risk is limited to an
acceptable level.
 
     The Company has adopted Statement of Financial Accounting Standards
("SFAS") No. 115, Accounting for Certain Investments in Debt and Equity
Securities, and classifies its investments as available-for-sale in accordance
with that standard. Available-for-sale securities are carried at fair value.
Unrealized gains and losses, net of tax, are reported in stockholders' equity.
Realized gains and losses and declines in value judged to be
other-than-temporary, if any, on available-for-sale securities will be included
in investment income. The cost of securities sold is based on the specific
identification method.
 
CONCENTRATION OF CREDIT RISK
 
     The Company sells its products primarily to large, multinational customers
in the United States, Europe, Canada and Australia. The Company derived 26%, 42%
and 34% of its total revenues from customers outside the United States for the
years ended December 31, 1994, 1995 and 1996, respectively. A significant
concentration of the Company's customers are in the insurance and commercial
print service industries. No customer has accounted for 10% or more of the
Company's revenue in any one year.
 
     Credit is extended based on an evaluation of the customer's financial
condition and a cash deposit is generally not required. The Company estimates
its potential losses on trade receivables on an ongoing basis and provides for
anticipated losses in the period in which the revenues are recognized. Credit
losses have historically been minimal and have been within management's
expectations.
 
ACCOUNTING STANDARD ON IMPAIRMENT OF LONG-LIVED ASSETS
 
     In March 1995, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of, which requires impairment losses to be
recorded on long-lived assets used in operations when indicators of impairment
are present and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying amount. SFAS 121 also addresses the
accounting for long-lived assets that are expected to be disposed of. The
Company adopted SFAS 121 in 1996 and the adoption had no impact on the Company's
financial statements.
 
COMPUTER SOFTWARE COSTS
 
     In accordance with SFAS No. 86, Accounting for the Costs of Computer
Software to be Sold, Leased or Otherwise Marketed, costs incurred in the
research and development of new software products and significant enhancements
to existing software products are expensed as incurred until the technological
feasibility of the product has been established. After technological feasibility
has been established, direct production costs, including programming and
testing, are capitalized until general release of the product.
 
     Capitalized software costs are amortized using the greater of the amount
computed using the ratio of current period product revenues to estimated total
product revenues or the straight-line method over the remaining estimated
economic lives of the products (generally five years). It is possible that
estimated total product revenues, the estimated economic life of the product, or
both, will be reduced in the future. As a result, the carrying amount of
capitalized software costs may be reduced in the future, which could result in
charges to the results of operations in future periods.
 
DEPRECIATION AND AMORTIZATION
 
     Depreciation is provided on a straight-line method over the estimated
useful lives of the assets (generally five years). Amortization of leasehold
improvements is provided over the lesser of the remaining lease term or the
estimated useful life of the improvements.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
REVENUE RECOGNITION
 
     The Company recognizes revenue in accordance with AICPA Statement of
Position on Software Revenue Recognition No. 91-1. Initial license fee revenue
is recognized upon shipment of the product to customers if no significant
Company obligations remain and collection of the receivable is deemed probable.
The portion of the initial license fee revenue which represents the software
support for the first year is deferred and recognized ratably over the contract
period. In subsequent years, customers pay annual license fees for continued use
and support of licensed software. Annual renewal license and support fees
revenue is deferred and recognized ratably over the contract period. Revenues
from commissions paid by Xerox in connection with the sale of Xerox printer
products are recognized upon installation of the printer products. Revenues
generated from consulting and training services are recognized as the related
services are performed.
 
COMPUTATION OF NET INCOME PER SHARE
 
     Net income per share is computed using the weighted average number of
common shares and common stock equivalents outstanding. Common equivalent shares
from stock options and warrants are excluded from the computation when their
effect is antidilutive except that, pursuant to the Securities and Exchange
Commission Staff Accounting Bulletins, common shares and common equivalent
shares issued during the twelve months prior to the initial filing of the
Registration Statement with the Securities and Exchange Commission have been
included in the calculation as outstanding for all periods prior to the
Company's initial public offering (using the treasury stock method). The
calculation also gives effect to the conversion of all convertible preferred
shares (using the if-converted method), which automatically converted into
common shares upon completion of the Company's initial public offering.
 
STOCK OPTIONS
 
     In 1996, the Company adopted SFAS No. 123, Accounting for Stock-Based
Compensation. As permitted by the Statement, the Company has elected to continue
accounting for its stock-based compensation in accordance with the provisions of
APB 25. As such, the new provisions of SFAS 123 had no impact on the financial
position or results of operations of the Company.
 
INCOME TAXES
 
     The Company follows the liability method of accounting for income taxes, as
set forth in SFAS No. 109. The Company and Xerox had a Tax Sharing Agreement
that provided for the allocation between the Company and Xerox of all
responsibilities, liabilities and benefits relating to taxes paid or payable by
either the Company or Xerox for all taxable periods. Through September 19, 1996,
the Company was included in the consolidated tax returns of Xerox and the
Company's share of Xerox's consolidated income tax liability was determined on a
separate company basis computed under Internal Revenue Code guidelines. The
Company's income tax liability due to Xerox totaled $1,382,100 at December 31,
1995, which was paid in 1996, and $311,000 at September 19, 1996. Subsequent to
the Company's initial public offering on September 19, 1996, the Company was no
longer included in the consolidated tax returns of Xerox and will file separate
tax returns.

     As of December 31, 1996, 176,603 of the options were vested and exercisable
and 496,887 shares were available for future grant.
 
     Through December 31, 1996, the Company has recorded $440,000 of deferred
compensation on options granted to employees, representing the difference
between the option grant price and the deemed fair market value of the related
shares. The Company is amortizing such amount ratably over the vesting period of
the options, generally 48 months.
 
     Adjusted pro forma information regarding net income is required by SFAS
123, and has been determined as if the Company had accounted for its employee
stock options under the fair value method of that Statement. For options granted
in the year ended December 31, 1995 and the period ended September 19, 1996, the
fair value for options was estimated at the date of grant using the "minimum
value" method for option pricing with the following weighted-average
assumptions: risk-free interest rates of 6%; dividend yields of 0%; and a
weighted-average expected life of the option of seven years. For options granted
from September 19, 1996 to December 31, 1996, the fair value of options was
estimated at the date of grant using the "Black-Scholes" method for option
pricing with the following weighted-average assumptions: risk-free interest
rates of 6%; dividend yields of 0%; expected volatility of .7; and
weighted-average expected life of the option of seven years.
 
     For purposes of adjusted pro forma disclosures, the estimated fair value of
the options is amortized to expense over the options' vesting period. The effect

         (g)     Landlord acknowledges that the availability of sufficient

11.      REDECORATING

         DELETED IN ITS ENTIRETY

12.      COMPLIANCE WITH LAW

         Landlord covenants that the Demised Premises, the Premises and the
         Building, and the fixtures and appurtenances thereto (except those
         installed by Tenant) do conform or that Landlord will promptly cause
         them to conform to every applicable requirement of law or duly
         constituted authority or the requirements of the carriers of all
         insurance on or relating to the Demised Premises, the Premises or the

         federal ordinances in effect from time to time with respect to
         facilities for the handicapped in the Demised Premises, the Premises
         and the Building.


13.      LANDLORD'S TITLE, AUTHORITY AND QUIET ENJOYMENT

         Landlord covenants and represents that it has good and marketable
         title to the Building and the Complex, free and clear of all ground
         leases, liens and mortgages or deeds of trust affecting Tenant's
         possession of the Demised Premises, Tenant's use of the Premises, or
         the rights granted to Tenant hereunder, except: a mortgage/deed of
         trust dated Nov. 2, 1987 from Landlord, as mortgagor, and NEW ENGLAND
         MUTUAL LIFE INSURANCE COMPANY, a MASSACHUSETTS CORPORATION, as
         mortgagee/beneficiary of deed of trust.

         In the event this Lease or the leasehold estate created hereunder is
         subject to the prior rights of any mortgagee/beneficiary of deed of
         trust or ground lessor, then Landlord shall secure from such
         mortgagee/beneficiary of deed of trust or ground lessor a written
         agreement in recordable form, in the form of Exhibit "F",
         Non-Disturbance and Attornment Agreement (executed and acknowledged by
         and on behalf of such mortgagee/beneficiary of deed of trust, or
         ground lessor), which provides, among other things that Tenant, so
         long as Tenant is not in default hereunder, may remain in possession
         of the Demised Premises pursuant to the terms hereof and without
         diminution of Tenant's rights should Landlord become in default with
         respect to such mortgage or ground lease or should the Premises become
         the subject of any action to foreclose any mortgage or to dispossess
         Landlord.  Such agreement shall be secured and furnished to Tenant at
         the same time this executed Lease is delivered to Tenant.

         Landlord covenants and represents that it has full and complete
         authority to enter into this Lease under all of the terms, conditions
         and provisions set forth herein, and so long as Tenant keeps and
         substantially performs each and every term, provision and condition
         herein contained on the part of Tenant to be kept and performed,
         Tenant shall peacefully and quietly enjoy the Premises without
         hindrance or molestation by Landlord or by any other person claiming
         by, through or under Landlord.


14.      SUBORDINATION

         The priority of this Lease and the leasehold estate of Tenant created
         hereunder are and shall be subject and subordinate to the lien of any
         mortgage or ground lease, whether such mortgage is placed against the
         fee or leasehold estate, which may now or hereafter affect the
         Building and to all renewals, modifications, consolidations,
         replacements and extensions thereof, and advances thereunder,
         effective upon the date the mortgagee or ground lessor, as the case
         may be, shall deliver to Tenant a written agreement in the form of
         Exhibit "F", Non-Disturbance and Attornment





                                       6
<PAGE>   7
         Agreement (executed and acknowledged by and on behalf of the
         mortgagee/beneficiary of deed of trust, or ground lessor) in
         recordable form which provides, among other things that Tenant, so
         long as Tenant is not in default hereunder, may remain in possession
         of the Demised Premises pursuant to the terms hereof and without any
         diminution of the Tenant's rights should Landlord become in default
         with respect to such mortgage or ground lease or should the Premises
         become the subject of any action to foreclose any mortgage or to
         dispossess Landlord.  Any fee which Landlord's lender or ground lessor
         may charge for such agreement shall be paid by Landlord.


15.      ASSIGNMENT AND SUBLETTING

         Tenant shall have the right to assign this Lease or to sublease all or
         any portion of the Demised Premises, with Landlord's consent which
         consent shall not be unreasonably withheld or delayed.  Should
         Landlord fail to respond to Tenant's request within five (5) days
         Landlord's consent shall be deemed given.  Any such assignment or
         subletting shall not relieve Tenant of its obligations hereunder.

         In the event Tenant sells the operating unit which occupies the
         Demised Premises to another company, then anything to the contrary in
         this paragraph notwithstanding, Tenant shall have the right to assign
         this Lease to such other company, but Tenant shall not thereby be
         released of liability under this Lease.


16.      LEASE EXTENSION

         If this Lease shall not have been terminated pursuant to any
         provisions hereof and Tenant is not in default under the terms
         hereunder, then Tenant may, at Tenant's option, extend the term of
         this Lease for one (1) successive additional term of three (3) years,
         commencing on the expiration of the original term, or the immediately
         preceding additional term as the case may be, and in the event Tenant
         has elected to exercise its option to lease additional space pursuant
         to Paragraph 25 the option provided for herein shall include such
         additional space.  At least nine (9) months prior to the expiration of
         the initial term or any extended term, as the case may be, Tenant
         shall request from Landlord the fair market rental rate being charged
         in the Building, should Tenant desire to extend the term of this
         Lease.  At least eight (8) months prior to the expiration of the
         initial or any extended term Landlord shall notify Tenant, in writing,
         the applicable rental rate for the next succeeding option period.
         Tenant may exercise such option by giving Landlord written notice by a
         date which is the later to occur of (a) six (6) months prior to the
         expiration of the original term or the additional term, as the case
         may be, and (b) sixty (60) days after receipt by Tenant of Landlord's
         notice of the applicable rental rate, as hereinabove provided, and (c)
         fifteen (15) days after the fair market rental rate has been
         determined by arbitration.  Upon the giving by Tenant to Landlord of
         such written notice and the compliance by Landlord and Tenant with the
         foregoing provisions of this Paragraph 16, the term of this Lease
         shall by deemed to be automatically extended upon all the covenants,
         agreements, terms, provisions and conditions, set forth in this Lease,
         except rental which:

         (a)     During the first renewal term shall be limited to a maximum of
                 90% of the then fair market rental rate,

         (b)     Or if Tenant elects, the rental rate schedule shall be as
                 follows:
                 $1.65 per rentable square foot for months 36 through 48,
                 $1.70 per rentable square foot for months 49 through 60,
                 $1.75 per rentable square foot for months 61 through 72,

         (c)     Upon execution of this extension option, Landlord shall repaint
                 the Demised Premises with two (2) coats of prime quality paint;
                 repainting shall be performed in a workmanlike manner with a
                 minimum of interference with Tenant's normal business
                 operations and replace all carpeting, with a quality comparable
                 to the initial installation, in the Demised Premises and in any
                 adjoining lobby/reception area, and except for such terms and
                 conditions as shall be inapplicable during any additional term
                 or in connection with this Paragraph 16.





                                       7
<PAGE>   8
         The term "month" as used in this paragraph shall mean (a) if the
         Expiration Date is the last day of a calendar month, a calendar month,
         or (b) if the Expiration Date is not the last day of a calendar month,
         the period between the Expiration Date and the date in the preceding
         month which is one (1) day after the date in the month of the
         Expiration Date, e.g., if the Expiration Date falls on May 19, one (1)
         "month" prior thereto would be April 20 and two (2) "months" prior
         thereto would be March 20.

         With respect to the lease extensions, the applicable "fair market
         rental rate" shall be that rate charged for space of comparable size
         and condition in comparable buildings, including the Building, located
         in the geography commonly known as the Golden Train area of the City
         of San Diego, taking into consideration the location, quality and age
         of the building, floor level, extent of leasehold improvements
         (existing or to be provided) including the amount spent by Tenant for
         leasehold improvements over building standard in the Demised Premises,
         rental abatements, lease takeover/assumptions, moving expenses and
         other concessions, term of lease, extent of services to be provided,
         distinction between "gross" and "net" lease, a base year or amount for
         escalation purposes "both operating costs and ad valorem/real estate
         taxes" and the time the particular rental rate under consideration
         becomes or is to become effective, or any other relevant term or
         condition, including any allowances for leasehold improvements, thus,
         the "fair market value" rental rate may be a rental rate with or
         without an allowance and/or with or without various other concessions
         as set forth hereinabove.

         In the event Tenant disagrees with Landlord's determination of the
         fair market rental rate, Tenant shall promptly so notify Landlord and
         Landlord and Tenant shall thereupon negotiate in good faith to attempt
         to agree upon a mutually acceptable fair market rental rate, but in
         the event agreement has not been reached within thirty (30) days after
         Tenant's receipt of Landlord's Notice, then Tenant shall have the
         option to demand arbitration as provided in Paragraph 46 hereof.

         If Tenant fails or omits to so give to Landlord the first written
         notice referred to above, it shall be deemed, without further notice
         and without further agreement between the parties hereto, that Tenant
         elected not to exercise the options granted Tenant pursuant to this
         Paragraph 16 to extend the term of this Lease for additional periods.


17.      TAXES, ETC.

         Landlord shall pay all real estate taxes, assessments, water and sewer
         rates and charges, and any other charges which may be levied, assessed
         or charged against the Building and/or the Complex.  Landlord shall
         further make all payments required to be made under the terms of any
         mortgage or deed of trust or ground lease which is now or hereafter a
         lien on the building or the Complex which is superior to this Lease
         and all payments required to be made under any ground lease.  Landlord
         shall have a reasonable time to cure a default under the terms of the
         mortgage or deed of trust, before constituting an event of default by
         Landlord as hereinafter described in Paragraph 23 of this Lease.


18.      INSURANCE AND WAIVER OF LIABILITY

         Landlord shall provide, at its expense, throughout the term of this
         Lease, comprehensive general liability insurance covering the Building
         and the Premises, except when caused by the sole negligence of Tenant
         or Tenant's failure to perform its obligations under this Lease.  The
         policy or policies evidencing such insurance shall provide that same
         may not be cancelled or amended without fifteen (15) days prior
         written notice to Tenant, and shall provide for a combined coverage of
         bodily injury and property damage in an amount not less than Five
         Million Dollars ($5,000,000).  Such policy or policies shall be issued
         by an insurance company licensed to do business in the state in which
         the Building is situate.  Upon Tenant's request, Landlord shall submit
         to Tenant suitable evidence that the foregoing policy or policies are
         in effect.

         Tenant shall provide, at its expense, throughout the term of this
         Lease, comprehensive general liability insurance covering the Building
         and the Premises when caused by the sole negligence of Tenant or
         Tenant's failure to perform its obligations under this Lease.  The
         policy or policies evidencing such insurance shall provide that same
         may not be cancelled or amended without fifteen (15) days prior
         written notice to Landlord,





                                       8
<PAGE>   9
         and shall provide for a combined coverage of bodily injury and
         property damage in an amount not less than Five Million Dollars
         ($5,000,000).  Such policy or policies shall be issued by an
         insurance company licensed to do business in the state in which the
         Building is situate.  Upon Landlord's request, Tenant shall submit to
         Landlord suitable evidence that the foregoing policy or policies are
         in effect.  Notwithstanding the foregoing, Tenant may insure the
         foregoing risks under its blanket policy, or elect to self-insure such
         risks.

         Landlord, for itself and its insurers, hereby releases Tenant with
         respect to any liability (including that deriving from the fault or
         neglect of Tenant, assignees, subtenants, its agents, employees or
         other persons under its or their direction or control) which Tenant
         might otherwise have for any damage to the Building or the Demised
         Premises by fire, other casualty or cause which Landlord could have
         covered by a standard fire insurance policy with extended coverage
         endorsement.  The term "Tenant" as used in this paragraph shall
         include any subsidiary of Tenant and any assignee or subtenant of
         Tenant.

         Landlord shall insure the Building against fire or other casualty with
         extended coverage endorsement with an insurance company selected by
         Landlord and Landlord shall cause the policy evidencing such insurance
         to include provision permitting such release of liability if such a
         provision is obtainable from such insurer at no additional expense to
         Landlord.  If such insurer will not include such a provision in such
         policy, or if the inclusion of such provision in such policy would
         involve an additional expense for Landlord, Landlord shall so notify
         Tenant within a reasonable time.  Where such a provision is obtainable
         from such insurer and Tenant notifies Landlord in writing within a
         reasonable time thereafter that Tenant desires Landlord to cause such
         a provision to be included in such policy at the expense of Tenant,
         Landlord shall cause such a provision to be included, and Tenant
         agrees to pay promptly all expenses incurred by Landlord as a result
         of such inclusion.


19.      DAMAGE

         In the event that the Building or Premises are damaged for any reason
         whatsoever and Tenant is unable, in Tenant's reasonable business
         judgement, to carry on its normal business operations for a period of
         forty five (45) days or more, Tenant's shall have the right to
         terminate this Lease by giving written notice of such termination to
         the Landlord no later than thirty (30) days after the occurrence of
         such damage.  Upon such termination, Tenant's obligations hereunder
         and each of them, including the obligation to pay rent, shall cease
         and determine as of the day the Premises were so damaged.  If in
         Tenant's reasonable business judgement, it is unable to carry on its
         normal business operations for a period of less than forty five (45)
         days because of such damage, rent shall abate (or any free rent period
         provided for in Paragraph 3 hereof shall be extended) for the period
         the Premises are untenantable.

         In the event the Premises are partially damaged by fire or other
         casualty and Tenant shall determine that it is able to carry on its
         normal business operations, Tenant shall pay rent for only such
         portion of the Premises which Tenant in its determination may
         reasonably occupy during the time required to make repairs.  All
         repairs necessary to restore the Premises to its original condition
         shall be:

         (a)     commenced within thirty (30) days after the occurrence of such
                 damage;

         (b)     performed in a diligent and workmanlike manner with material
                 of at least the same quality utilized originally in the
                 construction of the Premises;

         (c)     completed by Landlord at Landlord's sole expense with a
                 minimum of interference with Tenant's normal business
                 operations.

         If in Tenant's determination Landlord shall not have performed any of
         the above obligations in strict compliance therewith, then Tenant may,
         but shall not be required to, undertake such obligations, and all
         costs and expenses incurred by Tenant as a result thereof may be
         deducted from any rent or other payment due or to become due
         hereunder.

20.      CONDEMNATION

         In the event the Building or the Complex shall be condemned for public
         use or voluntarily transferred to a public or quasi-public body in
         lieu of proceeding to a judgment of condemnation, this Lease shall
         terminate and rent shall be adjusted to the date of termination.  In
         the event a portion of the Building or the Complex shall be condemned
         for public use or voluntarily transferred to a quasi-public body in
         lieu of proceeding to a judgment of condemnation and Tenant is unable,
         in Tenant's reasonable business judgement, to carry on its normal
         business operations for a period of forty five (45) day's or more,
         Tenant-shall have the right to terminate this Lease by giving written
         notice of such termination to the Landlord no later than thirty (30)
         days after the occurrence of such condemnation or transferal.  Upon
         such termination, Tenant's obligations hereunder and each of them,
         including the obligation to pay rent, shall cease and determine as of
         the date of termination.  If in Tenant's determination, it is unable
         to carry on its normal business operations for a period of less than
         forty five (45) days because of such partial condemnation, rent shall
         abate for the period the Premises are untenantable.

         In the event a portion of the Building or Complex shall be condemned
         for public use or voluntarily transferred to a public or quasi-public
         body in lieu of proceeding to a judgment of condemnation, and Tenant
         shall determine that it is able to carry on its normal business
         operations, Tenant shall pay rent for only such portion which Tenant
         in its determination may reasonably occupy after such partial
         condemnation or transfer.  All repairs necessary to restore the
         Demised Premises, Premises, Building or the Complex as nearly as
         possible to its original condition shall be:

         (a)     commenced within thirty (30) days after the taking or
                 transfer;
 
         (b)     performed in a diligent and workmanlike manner with material
                 of at least the same quality utilized originally in the
                 construction of the Building or Complex.

         (c)     completed by Landlord at Landlord's sole expense with a
                 minimum of interference with Tenant's normal business 
                 operations.

         If in Tenant's determination Landlord shall not have performed any of
         the above obligations in strict compliance therewith, then Tenant may,
         but shall not be required to, undertake such obligations, and all
         costs and expenses incurred by Tenant as a result thereof may be
         deducted from any rent or other payment due or to become due
         hereunder.  Tenant is hereby granted a lien upon any award or
         settlement resulting from the condemnation to the extent that Tenant
         has not been reimbursed for any cost or expense which Tenant may have
         incurred hereunder.

         Except as provided in the paragraph immediately preceding, Tenant
         shall not be entitled to any award or settlement resulting from the
         condemnation, provided that nothing contained herein shall be
         construed to in any way restrict or limit Tenant from asserting a
         claim for any damages resulting from the taking of any leasehold
         improvements paid for by Tenant or moving expenses incurred as a
         result of such condemnation.


21.      DEFAULT BY TENANT

         The occurrence of any one or more of the following events shall
         constitute an event of default by Tenant:

        (a)      the failure by Tenant to make any payment of rent or any
                 other payment required to be made by Tenant hereunder, as and
                 when due, where such failure shall continue for a period of ten
                 (10) days after receipt of written notice thereof by Tenant
                 from Landlord;

        (b)      the failure by Tenant to observe or perform any of the
                 covenants, conditions or provisions of this Lease where such
                 failure shall continue for a period of thirty (30) days after
                 receipt of written notice thereof by Tenant from Landlord,
                 provided, however, that if the nature of Tenant's default is
                 such that it cannot be cured solely by payment of money and
                 that more than thirty (30) days may be reasonably required for
                 such cure, then Tenant shall not be deemed to be in default if
                 Tenant shall commence such cure within such thirty (30) day
                 period and shall thereafter diligently prosecute such cure to
                 completion;





                                       10
<PAGE>   11

         (c)     (i)      the making of any general arrangement or any
                          assignment by Tenant for the benefit of creditors;

                 (ii)     the filing by or against Tenant of a petition to have
                          Tenant adjudged a bankrupt or a petition of
                          reorganization or arrangement under any law relating
                          to bankruptcy (unless, in the case of a petition
                          filed against Tenant, when such petition is dismissed
                          within ninety (90) days);

                 (iii)    the appointment of a trustee or receiver to take
                          possession of substantially all of Tenant's assets;

                 (iv)     the attachment, execution or other judicial seizure
                          of substantially all of Tenant's assets.


22.      LANDLORD'S REMEDIES

         Upon the occurrence of an event of default under this Lease by Tenant,
         then Landlord in addition to other rights or remedies it may have,
         shall have the right to terminate this Lease upon fifteen (15) days
         written notice to Tenant, and also the right, with or without
         termination of this Lease, of reentry upon and taking possession of
         the Demised Premises and Landlord may remove all persons and property
         from the Demised Premises; such property may be removed and stored in
         any other place in the Building or in any other reasonably secure
         place for the account of and at the expense and risk of Tenant.
         Tenant hereby waives all claims for damages which may be caused by the
         reentry of Landlord and taking possession of the Demised Premises or
         removing or storing the furniture and property as herein provided and
         shall save Landlord harmless from any costs or damages occasioned
         Landlord thereby, and no such reentry shall be considered or be
         construed to be a forcible entry.  Should Landlord elect to reenter,
         as herein provided, or should it take possession pursuant to legal
         proceedings or pursuant to any notice provided for by law, Landlord
         may either terminate this Lease or, Landlord may from time to time,
         without terminating this Lease, relet the Demised Premises or any part
         thereof for such term or terms and at such rental or rentals and upon
         such other terms and conditions as may be reasonable, with the right
         to make minor alterations and repairs to the Demised Premises.  Rental
         received by Landlord from such reletting shall be applied first, to
         the payment of any costs of such reletting including reasonable
         brokerage and attorney's fee; and the residue, if any, shall be held
         by Landlord and applied in payment of future rent as the same may
         become due and payable hereunder.  Should such rentals received from
         such reletting in any during month be less than one-twelfth (1/12) of
         the annual rent reserve hereunder, then Tenant shall pay such
         deficiency to Landlord.  Such deficiency shall be calculated and paid
         monthly.  No such reentry or taking possession of the Demised Premises
         by Landlord shall be construed as an election on its part to terminate
         this Lease, unless written notice of such intention be given to
         Tenant, in which event Tenant's obligations to Landlord shall
         forthwith cease, or unless the termination thereof be decreed by a
         court of competent jurisdiction.


23.      DEFAULT BY LANDLORD

         The occurrence of any one or more of the following events shall
         constitute an event of default by Landlord:

         (a)     The failure by Landlord to make any payment required to be
                 made by Landlord hereunder, as and when due, where such
                 failure shall continue for a period of ten (10) days after
                 receipt of written notice thereof from Tenant to Landlord;

         (b)     The failure by Landlord to observe or perform any of the
                 covenants, conditions or provisions of this Lease where such
                 failure shall continue for a period of thirty (30) days after
                 receipt of written notice thereof from Tenant to Landlord;
                 provided however, that if the nature of Landlord's default is
                 such that it cannot be cured solely by payment of money and
                 that more than thirty (30) days may be reasonably required for
                 such cure, then Landlord shall not be deemed to be in default
                 if Landlord shall commence such cure within such thirty (30)
                 day period and shall thereafter diligently prosecute such cure
                 to completion.

24.      TENANTS REMEDIES

         Upon the occurrence of an event of default under this Lease by
         Landlord, then Tenant in addition to other rights or remedies it may
         have, at Tenant's sole option, may set off any amount owed to Tenant
         by Landlord against any rent or other payment due or to become due
         hereunder or perform any obligations of Landlord (which Landlord has
         failed to perform) in which event Tenant shall have the right to set
         off any expense incurred thereby against any rent or other payment due
         or to become due hereunder.


25.      ADDITIONAL SPACE

         Landlord hereby grants to Tenant the right to lease additional space
         contiguous to the Demised Premises and any other location in Building
         1 upon the following terms and conditions:

         (a)     No later than four (4) months prior to the time additional
                 space in Building 1 by Tenant, Tenant shall notify Landlord in
                 writing that Tenant elects to exercise this right.

         (b)     Within fifteen (15) days after Landlord receives such notice,
                 Landlord shall inform Tenant in writing the exact date
                 additional space shall be available for preparation by Tenant.
                 Provided that Tenant exercises this right Between months 1 and
                 12 inclusive of this original Term Landlord agrees to
                 contribute toward the preparation of additional space the same
                 sum of dollars per rentable square foot as was required
                 buildout Tenant's original improvements multiplied by the
                 number of additional rentable square feet.  If however, Tenant
                 exercises this right between months 13 and 36 inclusive of
                 this original Term, Landlord agrees to only perform touch-up
                 painting and carpet cleaning for any additional rentable
                 square feet to be leased.  All improvements required to be
                 made hereunder shall be of the same and/or similar quality
                 required to be furnished with respect to the completion of the
                 Demised Premises.

         (c)     The rent for any additional space shall be computed at the
                 same annual rate per square foot as the rent for the space
                 described in Paragraph 1 hereof and shall commence on the date
                 the additional space has been completed in accordance with (b)
                 above as the case may be.

         (h)     The term of the Lease for such additional space shall be the
                 balance of the term of this Lease and any additional term
                 thereof.

         (i)     Landlord shall provide Tenant with additional parking spaces
                 in the event Tenant elects to lease additional space in the
                 same ratio set forth in Paragraph 10 (h).

         (j)     All of the terms and conditions of this Lease not inconsistent
                 with this Paragraph 25 shall govern the leasing of any
                 additional space.

         (k)     Any space added to the Demised Premises pursuant to this
                 Paragraph 25 shall thereafter be deemed to be a part of and
                 included in the Demised Premises.

28.      FIRST RIGHT TO LEASE

         If, during the original or any additional term hereof, Landlord elects
         to lease any space in Building 2 of Governor Park Plaza, 6363
         Greenwich Drive, then Landlord shall first offer such space in writing
         to Tenant on terms and conditions no less favorable than those offered
         to third parties.  If within twelve (12) days after receipt of such
         offer, Tenant does not notify Landlord that Tenant elects to lease
         such space, then Landlord shall be relieved of any obligations to
         Tenant with regard to any such offering; provided, however, that a
         failure by Tenant to lease any specific space when so offered by
         Landlord shall not relieve Landlord of its obligation to first offer
         Tenant any other space in Building 2 if, as and when Landlord elects
         to offer such other space to third parties.


29.      RENT ABATEMENT

         Should Tenant or those holding by, through or under Tenant not occupy
         all or any portion of the Demised Premises for any period during the
         term hereof or any additional term for any reason whatsoever, then
         anything herein to the contrary notwithstanding, Landlord and Tenant
         shall mutually agree to the percentage of the monthly rent for which
         Tenant is or might be obligated to pay based on the previous 6 month
         Operating Expense history for the Complex, and which the parties agree
         constitutes the cost of providing the services set forth in Paragraph
         10 shall abate for as long as that portion of the Demised Premises are
         not so occupied.


30.      DELIVERY OF EXECUTED LEASE AND RELATED DOCUMENTS

         Within fifteen (15) days after Tenant delivers to Landlord four (4)
         duplicate originals of this Lease duly executed by Tenant, Landlord
         shall deliver to Tenant two (2) fully executed originals of this Lease
         accompanied by agreements in the Form of Exhibit "F" (Non-Disturbance
         and Attornment Agreement) duly executed and acknowledged by and on
         behalf of each mortgagee/beneficiary of deed of trust referred to in
         Paragraph 13 hereof, and if requested by Tenant, a Memorandum of Lease
         in the form of Exhibit "G" duly executed and acknowledged by and on
         behalf of Landlord (said executed Lease, Non-Disturbance Agreement(s)
         and Memorandum of Lease are together referred to herein as the Lease
         and Related Documents").  In the event Landlord shall fail to deliver
         the fully executed Lease and Related Documents as herein required,
         Tenant may, if Tenant so elects, withdraw its execution and delivery
         of this Lease by giving Landlord written notice of such withdrawal.
         Upon such withdrawal neither party shall have any rights against the
         other either hereunder or otherwise except that Landlord shall
         forthwith return to Tenant any sums which Tenant shall have paid to
         Landlord prior to such withdrawal.


31.      TERMINATION

         Landlord hereby grants to Tenant the right to terminate this Lease at

         days prior written notice to Landlord.  In the event Tenant elects to
         terminate the Lease as herein provided, Tenant shall pay to Landlord
         an amount equal to thirty-five percent (35%) of the annual rental set
         forth in Paragraph 3 hereof (as it may have been amended by Paragraphs
         16, 25 and 26 hereof) from the date of termination through the balance
         of the unexpired term of the Lease.  Such payment shall be made on or
         before the date such termination becomes effective.

36.      INDUSTRIAL DEVELOPMENT BONDS

  Landlord covenants, warrants and represents that tax exempt Industrial
  Development Bonds, sometimes referred to as Industrial Revenue Bonds
  ("I.R.B.s") were not used in financing the Complex or the Building.  If it is
  subsequently determined that tax exempt I.R.B.s were used in such financing,
  Tenant shall have the right and option to terminate this Lease and thereafter
  be relieved of all further liability hereunder.

                        -----  
  Landlord covenants, warrants and represents that to the best of its
  knowledge, after thorough investigation, the Premises and the Building
  (including the land thereunder) do not contain any environmental contaminants
  ("toxic contamination") of any kind (including PCBs, except for PCBs that are
  totally contained within light fixtures and exterior transformers).  At any
  time during the term of this Lease, Tenant shall have the right and option,
  at Tenant's expense, to investigate the Building for the presence of asbestos
  and PCBs and to investigate the land for the presence of toxic contamination.

  Landlord agrees to indemnify and hold Tenant harmless from any claims or
  actions related to or arising out of any subsequent discovery of friable

  term, except for normal wear and tear and damage caused by the elements,
  casualty, or any other cause for which Tenant might not be liable, provided,
  however, that Tenant shall have the option, but not the obligation, to remove
  any or all of the improvements and alterations made to the Demised Premises by

        hereto to insist in any one or more cases upon the strict performance of
        any term, covenant or condition of this Lease to be performed or
        observed by the other party hereto shall not constitute a waiver or
        relinquishment for the future of any such term, covenant or condition.


42.     MEMORANDUM OF LEASE

        Neither party shall record this Lease or any of the exhibits and/or
        riders attached hereto, (except that Tenant may record the executed
        Non-Disturbance and Attornment Agreement) but at the request of either
        party, Landlord and Tenant shall enter into a "short form" or Memorandum
        of Lease in recordable form, attached hereto as Exhibit "G" and made a
        part hereof, which may be recorded and which shall set forth the

        This Lease represents the entire agreement between Landlord and Tenant
        and supercedes all prior agreements both written and oral.  The terms,
        covenants and conditions of this Lease shall be binding upon and shall
        inure to the benefit of Landlord and Tenant and their respective

        Complex is situate.  Should any provisions of this Lease require
        judicial interpretation, it is agreed that the court interpreting or
        construing the same shall not apply a presumption that the terms of any
        such provision shall be more strictly construed against one party or the
        other by reason of the rule of construction that a document is to be
        construed most strictly against the party who itself or through its
        agent prepared the same, it being agreed that the agents of all parties
        hereto have participated in the preparation of this Lease.

        leases in office buildings within the City of San Diego, State of

        Complex or be or have been associated or affiliated with either Landlord
        or Tenant.

        In the event Landlord and Tenant, or the two arbitrators fail or refuse
        to appoint an arbitrator within the time set forth herein, then either
        party shall have the right to petition the senior judge (in terms of

2.     If, at any time Mortgagee (or any person, or such person's successors or
       assigns, who acquired the interest of the Landlord under the Lease
       through foreclosure action of the Mortgage or otherwise) shall succeed
       to the rights of the Landlord under the Lease as a result of a default
       or event of default under the Mortgage, and if the Tenant is not then in
       default under the lease beyond the time permitted therein to cure such
       default, the (i) Lease shall not terminate, (ii) Upon receipt by Tenant
       of written notice of such succession of interest, Tenant shall attorn to

       conditions of the Lease and as hereinafter provided in this Paragraph 2,
       and (iii) Successor Landlord shall accept such Attornment and recognize

       effect as, or as if it were, a direct lease between the Successor
       Landlord and Tenant upon all of the then executory terms, conditions and
       covenants(including any right under the lease on the part of Tenant to
       extend the term of the lease) as are set forth in the Lease and which
       shall be applicable after such attornment and recognition.


3.     Tenant confirms that the lien or priority of the Lease shall at all

       the liens, security titles and security interests of the documents
       evidencing and securing such additional financing, and to any increases

       subrogation shall not derogate any of Tenant's rights, or Landlord's
       obligations, under said Lease.


4.     Tenant certifies that there are no defaults on the part of the Landlord
       under the Lease known to Tenant, that the Lease is a complete statement
       of the agreement of the parties thereto with respect to the letting of
       the Building, that the Lease is in full force and effect and that all
       conditions to the effectiveness or continuing effectiveness thereof
       required to be satisfied at the date hereof have been satisfied.


5.     Tenant will notify Mortgagee of any default of the Landlord under the
       Lease which would entitle Tenant to cancel the Lease or abate the rent
       or additional rent payable thereunder, and agrees that notwithstanding
       any provisions of the Lease, no notice of cancellation thereof shall be
       effective unless Mortgagee has received the notice aforesaid and has
       failed within thirty (30) days of the date thereof to cure the default,
       or if the default cannot be cured within thirty (30) days, has failed to
       commence and to diligently prosecute the curing of the default which
       gave rise to such right of cancellation or abatement.  All such notices
       shall be in writing and shall be deemed to have been given when

       addressed as follows:

                          ______________________________

OPERATING EXPENSES, REAL ESTATE TAXES AND UTILITY COSTS ESCALATION RIDER

Landlord and Tenant each acknowledge that the rent specified in Paragraph 3
does not provide for changes in Operating Expenses, Real Estate Taxes, and
Utility Costs which may hereafter pertain to the Demised Premises or the
Building.  Therefore, in addition to the rent (but not as additional rent)
Tenant shall pay Landlord its pro rata share of reasonable and customary
Operating Expenses, Real Estate Taxes and Utility Costs as hereinafter
provided:


(a)      The term "OPERATING EXPENSES" shall include the following annual
         expenses of Landlord for the operation and maintenance of the Complex
         of which the Demised Premises are a part:

         o    janitorial expenses;

         o    premiums for fire and casualty insurance required to be carried by
              Landlord pursuant to this Lease;

         o    cost of all maintenance and service agreements;

         o    cost of supplies and materials used in the operation and 
              maintenance of the Complex;

         o    employees directly and exclusively involved in the operation
              and maintenance of the Building and the Complex;

         o    all costs and expenses (other than those of a capital nature) of
              maintaining and repairing, paving and restriping, curbs,
              walkways, landscaping and the common areas of the Building,
              except in the event that during the last two (2) years of the
              term or extended term, as the case may be, Landlord elects to
              perform a single maintenance and repair project which causes
              Operating Expenses to be increased during such year by more than
              five percent (5%) over the previous years Operating Expenses,
              then in such event Tenant's obligation to reimburse Landlord for
              Operating Expenses during the year in which Landlord performed
              such single maintenance and repair project shall be limited to a
              maximum of five percent (5%) over the previous years costs for
              Operating Expenses.

         o    normal maintenance of mechanical and electrical equipment,
              including heating, ventilating, and air conditioning equipment
              but excluding capital expenditures;

         All expenses to be taken into account pursuant to this paragraph shall
         be "net" only, and for such purpose shall be deemed reduced by the
         amount of reimbursement, recoupment, payment, discount or allowance
         received or receivable by Landlord in connection with such expenses.

The term "OPERATING EXPENSES" shall exclude the following annual expenses of
Landlord:

         o    the cost of any work or service performed or rendered exclusively
              for any tenant, including Tenant, and the cost of making any
              installation or alteration to the Building and Complex which under
              generally accepted accounting principles are properly classified
              as capital expenditures;

         o    premiums for public liability insurance;

         o    brokerage commissions or other fees and other costs incurred in
              procuring tenants;

         o    management fees and administrative wages and salaries, including
              executives and officers of Landlord;

         o    depreciation, franchise or income taxes imposed on Landlord;


                                       1
<PAGE>   31
       o    advertising expenses;

       o    the cost of painting, repainting, decorating and redecorating for
            any tenant, including Tenant, of the Building and the Complex;

       o    maintenance and repair of capital items not a part of the Building;

       o    the cost of installing, operating and maintaining any specialty
            services, such as an observatory, broadcasting and/or
            telecommunication facility, data processing facility, luncheon
            club, retail store, sundries shop, newsstand, concession, athletic
            or recreational club;

       o    the cost of correcting defects in the construction of the Premises,
            Building and the Complex;

       o    the cost of any work or service performed for any tenant of the
            Building and Complex (other than Tenant) to a greater extent
            or in a materially more favorable manner than that furnished
            generally to the tenants and other occupants;

       o    the cost of any items for which Landlord is reimbursed by
            insurance, condemnation, refund, rebate or otherwise;

       o    the cost of any addition or additions to the Building or the
            Complex after the Commencement Date of this Lease;

       o    the cost of any repairs made by Landlord pursuant to the Damage or
            Condemnation paragraphs in the Lease;

       o    interest and amortization on any mortgage or deed of trust and any
            rent paid on any ground or underlying lease;

       o    any costs representing an amount paid to an entity related to
            Landlord which is in excess of the amount which would have
            been paid in the absence of such relationship;

       o    payments for rented equipment, the cost of which equipment would
            constitute a capital expenditure if the equipment were purchased;

       o    any expenses for repairs or maintenance which are covered by
            warranties, guarantees and service contracts (excluding any
            mandatory deductible);

       o    legal expenses arising out of the construction, operation, use,
            occupation or maintenance of the Building or Land or the
            enforcement of the provisions of any agreements affecting the Land
            or Building, including without limitation this Lease;

       o    increases in premiums for insurance required to be carried by
            Landlord pursuant to this Lease when such increase is
            caused by use of the Building by Landlord or any other tenant of
            Landlord which is hazardous on account of fire or otherwise, or
            premiums for any insurance carried by Landlord which is not
            required to be carried pursuant to this Lease.

       o    new items of maintenance or services for all tenants of the
            Building not included in the Operating Expense Base Year Statement,
            unless the Operating Expense Base Year Statement is revised to
            include such new items of maintenance or services.


(b)    The term "REAL ESTATE TAXES" shall mean the annual ad valorem taxes
       levied against the Building and Complex of which the Demised Premises
       are a part, by any authority having the direct power so to tax,
       including any city, county, state, or federal government, or any school,
       agricultural, transportation or environmental control agency, lighting,
       drainage or other improvement district thereof.  All expenses to be
       taken into account pursuant to this paragraph shall be "net' only, and
       for such purpose shall be deemed reduced by the amount of reimbursement,
       recoupment, payment, discount or allowance received or receivable by
       Landlord in connection with such expenses.  The term "Real Estate Taxes"
       shall not include any assessment for local improvements, license fee,
       penalty, inheritance or estate tax, any tax on Landlord's right to rent
       or other income from the Complex or on


                                       2
<PAGE>   32
       Landlord's business of leasing the Building, any penalty for delinquent
       payment of taxes, increases in taxes arising from additions or
       improvements to the Building or Complex (including leasehold improvements
       made by or for other tenants made subsequent to the Building having been
       assessed as a fully completed building), and increases in taxes due to a
       reassessment of the Building and/or Complex due to Landlord's sale
       thereof.  In the event the Building and/or land or Complex is reassessed
       (which term includes the current assessment being increased without
       reassessment) and such reassessment is greater than the prior assessment,
       then Landlord shall (a) promptly notify Tenant thereof, and (b) if in
       Tenant's reasonable determination such reassessment is excessive and
       Tenant so notifies Landlord, Landlord shall diligently protest such
       reassessment.  In the event Landlord fails so to notify Tenant, or to
       contest the reassessment (as the case may be), then Tenant's obligation
       to pay its share of Real Estate Taxes shall be computed by multiplying
       the prior assessment by the then current tax rate.


(c)    The term "UTILITY COSTS" shall include the following annual expenses of
       Landlord for the operation and maintenance of the Building and the
       Complex.  Utility charges for water, electricity, sewerage, and gas, all
       accrued and based on a calendar year operation.  All expenses to be taken
       into account pursuant to this paragraph shall be "net" only, and for such
       purpose shall be deemed reduced by the amount of reimbursement,
       recoupment, payment, discount or allowance received or receivable by
       Landlord in connection with such expenses, whether from utilities or any
       tenant in the Building.

(d)    (1)       The Base Year for Operating Expenses and Utility Costs shall
                 be the calendar year 1992.  In the event the Building was not
                 one hundred percent (100%) occupied at the commencement of the
                 Base Year, then for purposes of establishing the Base Year
                 costs, the actual Operating Expenses and Utility Costs shall
                 be adjusted upward as if the Building were one hundred percent
                 (100%) occupied.

       (2)       The Base Year for "Real Estate Taxes" shall be the later of
                 (a) the annual tax levy year next following that in which the
                 Commencement Date occurs, and (b) the annual tax levy year
                 next following the date on which the Building was fully
                 assessed as a fully completed building (including all tenant
                 leasehold improvements).

        (3)      Upon the request of either Landlord or Tenant, Landlord and
                 Tenant agree to convert the Base Year and each succeeding
                 twelve (12) month period to a calendar year basis, the
                 computation in making such a conversion to be acceptable to
                 both Landlord and Tenant.

(e)      Initially, Tenant's pro rata share shall be 6.77% calculated by
         dividing the number of rentable square feet demised to Tenant (7,042
         rentable square feet) by the number of rentable square feet in the
         Building (103,977 rentable square feet).  Tenant's pro rata share
         shall be adjusted during the term of said Lease and any renewals
         thereof by any increases or decreases in the square feet demised to
         Tenant and by any increases in the square feet in the Building.

(f)      Within ninety (90) days after the end of the Base Year and each
         anniversary thereof, the Landlord shall deliver to Tenant in Stamford,
         Connecticut (Attention: RE/GSD Lease Administration), a statement
         setting forth the amounts of Operating Expenses, Real Estate Taxes,
         and Utility Costs for the Base Year, and the amounts relative to the
         then current year, together with an invoice showing the amounts of
         increase or decrease for reimbursement.  Copies of the accounting
         statements used in the calculations and copies of receipted real
         estate tax bills, shall be furnished with the statements and invoice
         for reimbursement, and upon request by Tenant, Landlord shall submit
         additional back-up data (including copies of receipted bills) to
         permit Tenant to review such statement.  Tenant or any authorized
         agent of Tenant shall have the right, upon prior written notice, to
         audit Landlord's books at any time with respect to the Base Year or
         any subsequent year.  Upon request by Tenant, Landlord shall submit a
         statement signed by an officer (or partner, as the case may be) of
         Landlord, setting forth the percentage of occupancy of the Building at
         the Commencement of the Base Year.

(g)      In the event the Complex contains buildings in addition to the
         Building or land in excess of that required to support the Building,
         parking and common areas for the Building, and Landlord is unable to
         obtain a separate tax assessment of the Building, parking and common
         areas, the Landlord shall make a reasonable allocation for the


                                       3
<PAGE>   33
       the entire Complex.  Landlord shall also make such a reasonable
       allocation of any Operating Expenses and Utilities Costs attributable to
       the entire Complex.  In both cases, Landlord shall submit to Tenant
       sufficient back-up data as to the basis for such allocation to permit
       Tenant to determine the reasonableness of the allocation.  In the event
       that Tenant disputes the reasonableness of either such allocation,
       Landlord and Tenant agree to submit the determination of such allocation
       to arbitration in accordance with the rules of the American Arbitration
       Association.

(h)    Tenant shall pay such reimbursement due, if any, within thirty (30) days
       from receiving the remove statement, the required documentation and the
       requested documentation.  If Tenant shall dispute, in good faith, any
       reimbursement item or other sum (other than Rent) claimed by Landlord
       hereunder and Tenant shall give Landlord written notice specifying in
       reasonable detail the basis for its dispute, Tenant may withhold payment
       of the particular amount in dispute and shall not be deemed to be in
       default hereunder by reason of withholding such amount unless and until
       such dispute is determined adversely to Tenant and Tenant shall fail to
       pay the withheld amount, or the portion thereof as shall be determined to
       be payable to Landlord, within fifteen (15) days of the resolution of
       such dispute.  Tenant and Landlord shall proceed diligently to resolve
       any such dispute by agreement or arbitration in accordance with the rules
       of the American Arbitration Association.

(i)    Tenant shall have the right but not the obligation to pay any
       reimbursement due Landlord, as determined above, in twelve (12) equal
       monthly payments at the same time and in the same manner as rent.

(j)    If the first or final billing period during the term or any additional
       term of this Lease for which reimbursement may be due, shall contain less
       than twelve (12) months, the reimbursement under this Rider shall be
       prorated.

(k)    Landlord and Tenant stipulate and agree that of the rent set forth in
       Paragraph 3 hereof, $0.55 per rentable square foot per month has been
       allocated to the estimated cost of Operating Expenses, Real Estate Taxes
       and Utility Costs.  In the event the actual Operating Expenses, Real
       Estate Taxes and Utility Costs per square foot for the Building or
       Complex, as the case may be, for the Base Year or any subsequent year are
       less than $0.55 per rentable square foot per month, then the Landlord
       shall pay Tenant the difference multiplied by the number of square feet
       then leased to Tenant.  Landlord shall pay such amount to Tenant within
       thirty (30) days from sending the above statement, the required
       documentation and the requested documentation.

(1)    Tenant's obligation to reimburse Landlord for monies, under this Rider,
       shall be limited to a maximum of $0.66 per rentable square foot per month
       of space under Lease to Tenant during any one year.

(m)    Notwithstanding the foregoing provisions of this Rider, it is understood
       and agreed that in the event Landlord fails to bill Tenant for any
       amounts which may be due hereunder within four (4) months after the Base
       Year or any anniversary thereof, then Tenant shall have no liability or
       obligation to make such payment.

accordance with preliminary plans and specifications which shall be agreed to by
Landlord and Tenant. Such plans and specifications shall be deemed to be Exhibit

One and No/100ths ($ 1.00) Dollar per rentable square foot of unspent monies
would equate to 2 cents per square foot per month that would be added to the

additional term of five (5) years commencing on the expiration on the Extension
Term. Tenant shall be required to provide at least one hundred twenty (120) days
written notice prior to the expiration of the lease term. Tenant shall then
request from Landlord the "fair market rental rate" being charged in the

rental rate, Tenant shall promptly so notify Landlord and Landlord and Tenant

exercise the options granted Tenant pursuant to this Paragraph 16 to extend the
term of this Lease for additional periods."

between Landlord and Tenant."

22.      LANDLORDS REMEDIES

         Upon the occurrence of an event of default under this Lease by Tenant,
         then Landlord in addition to other rights or remedies it may have,
         shall have the right to terminate this Lease upon fifteen (15) days
         written notice to Tenant, and also the right, with or without
         termination of this Lease, of reentry upon and taking possession of the
         Demised Premises and Landlord may remove all persons and property from
         the Demised Premises; such property may be removed and stored in any
         other place in the Building or in any other reasonably secure place for
         the account of and at the expense and risk of Tenant. Tenant hereby
         waives all claims for damages which may be caused by the reentry of
         Landlord and taking possession of the Demised Premises or removing or
         storing the furniture and property as herein provided and shall save
         Landlord harmless from any costs or damages occasioned Landlord
         thereby, and no such reentry shall be considered or be construed to be
         a forcible entry. Should Landlord elect to reenter, as herein provided,
         or should it take possession pursuant to legal proceedings or pursuant
         to any notice provided for by law, Landlord may either terminate this
         Lease or, Landlord may from time to time, without terminating this
         Lease, relet the Demised Premises or any part thereof for such term or
         terms and at such rental or rentals and upon such other terms and
         conditions as may be reasonable, with the right to make minor
         alterations and repairs to the Demised Premises. Rental received by
         Landlord from such reletting shall be applied first, to the payment of
         any costs of such relettinq including reasonable brokerage and
         attorney's fee; and the residue, if any, shall be-held by Landlord and
         applied in payment of future rent as the same may become due and
         payable hereunder. Should such rentals received from such relenting
         during any month be less than one-twelfth (1/12) of the annual rent
         reserved hereunder, then Tenant shall pay such deficiency to Landlord.
         Such deficiency shall be calculated and paid monthly. No such reentry
         or taking possession of the Demised Premises by Landlord shall be
         construed as an election on its part to terminate this Lease, unless
         written notice of such intention be given to Tenant, in which event
         Tenant's obligations to Landlord shall forthwith cease, or unless the
         termination thereof be decreed by a court of competent jurisdiction.


23.      DEFAULT BY LANDLORD

         The occurrence of any one or more of the following events shall
         constitute an event of default by Landlord:

         (a)      The failure by Landlord to make any payment required to be
                  made by Landlord hereunder, as and when due, where such
                  failure shall continue for a period of ten (10)days after
                  receipt of written notice thereof from Tenant to Landlord;

         (b)      The failure by Landlord to observe or perform any of the
                  covenants, conditions or provisions of this Lease where such
                  failure shall continue for a period of thirty (30) days after
                  receipt of written notice thereof from Tenant to Landlord;
                  provided however, that if the nature of Landlord's default is
                  such that it cannot be cured solely by payment of money and
                  that more than thirty (30) days may be reasonably required for
                  such cure, then Landlord shall not be deemed to be in default
                  if Landlord shall commence such cure within such 
<PAGE>   64
                  thirty (30) day period and shall thereafter diligently
                  prosecute such cure to completion.

24.      TENANT'S REMEDIES

         Upon the occurrence of an event of default under this Lease by
         Landlord, then Tenant in addition to other rights or remedies it may
         have, at Tenant's sole option, may set off any amount owed to Tenant by
         Landlord against any rent or other payment due or to become due
         hereunder or perform any obligations of Landlord (which Landlord has
         failed to perform) in which event Tenant shall have the right to set
         off any expense incurred thereby against any rent or other payment due
         or to become due hereunder.


25.      ADDITIONAL SPACE

         Landlord hereby grants to Tenant the right to lease additional space
         contiguous to the Demised Premises and any other location in Building 1
         upon the following terms and conditions:

         (a)      No later than four (4) months prior to the time additional
                  space in Building I by Tenant, Tenant shall notify Landlord in
                  writing that Tenant elects to exercise this right.

         (b)      Within fifteen (15) days after Landlord receives such notice,
                  Landlord shall inform Tenant in writing the exact date
                  additional space shall be available for preparation by Tenant.
                  Provided that Tenant exercises this right Between months 1 and
                  12 inclusive of this original Term Landlord agrees to
                  contribute toward the preparation of additional space the same
                  sum of dollars per rentable square foot as was required
                  buildout Tenant's original improvements multiplied by the
                  number of additional rentable square feet. If however, Tenant
                  exercises this right between months 13 and 36 inclusive of
                  this original Term, Landlord agrees to only perform touch-up
                  painting and carpet cleaning for any additional rentable
                  square feet to be leased. All improvements required to be made
                  hereunder shall be of the same and/or similar quality required
                  to be furnished with respect to the completion of the Demised
                  Premises.

         (c)      The rent for any additional space shall be computed at the
                  same annual rate per square foot as the rent for the space
                  described in Paragraph 1 hereof and shall commence on the date
                  the additional space has been completed in accordance with (b)
                  above as the case may be.

         (h)      The term of the Lease for such additional space shall be the
                  balance of the term of this Lease and any additional term
                  thereof.

         (i)      Landlord shall provide Tenant with additional parking spaces
                  in the event Tenant elects to lease additional space in the
                  same ratio set forth in Paragraph 10 (h).

         (j)      All of the terms and conditions of this Lease not inconsistent
                  with this Paragraph 25 shall govern the leasing of any
                  additional space.

         (k)      Any space added to the Demised Premises pursuant to this
                  Paragraph 25 shall thereafter be deemed to be a part of and
                  included in the Demised Premises.

         If, during the original or any additional term hereof, Landlord elects
         to lease any space in Building 2 of Governor Park Plaza, 6363 Greenwich
         Drive, then Landlord shall first offer such space in writing to Tenant
         on terms and conditions no less favorable than those offered to third
         parties. If within twelve (12) days after receipt of such offer, Tenant
         does not notify Landlord that Tenant elects to lease such space, then
         Landlord shall be relieved of any obligations to Tenant with regard to
         any such offering; provided, however that a failure by Tenant to lease
         any specific space when so offered by Landlord shall not relieve
         Landlord of its obligation to first offer Tenant any other space in
         Building 2 if, as and when Landlord elects to offer such other space to
         third parties.


29.      RENT ABATEMENT

         Lease by giving Landlord written notice of such withdrawal. Upon such
         withdrawal neither party shall have any rights against the other either
         hereunder or otherwise except that Landlord shall forthwith return to

         withdrawal.

         1. Purpose. The purpose of the Plan is to provide employees of the
Company and its Designated Subsidiaries with an opportunity to purchase Common
Stock of the Company through accumulated payroll deductions. It is the intention
of the company to have the Plan qualify as an "Employee Stock Purchase Plan"
under Section 423 of the Internal Revenue Code of 1986, as amended. The
provisions of the Plan, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code.

Company. Where the period of leave exceeds 90 days and the individual's right to

relationship will be deemed to have terminated on the 91st day of such leave.

recognized securities dealer but selling prices are not reported, its Fair
Market Value shall be the mean of the closing bid and asked prices for the
Common Stock on the date of such determination, as reported in The Wall Street
Journal or such other source as the Board deems reliable, or;

                           (3) In the absence of an established market for the

the Board.

be determined as of the trading day immediately preceding the Enrollment Date.

                  (o) "Reserves" shall mean the number of Treasury Shares
covered by each option under the Plan which have not yet been exercised and the
number of Treasury Shares which have been authorized for issuance under the Plan

employed by the Company on a given Enrollment Date shall be eligible to

                  (b) Any provisions of the Plan to the contrary

extent, immediately after the grant, such Employee (or any other person whose
stock would be attributed to such Employee pursuant to Section 424(d) of the
Code) would own capital stock and/or hold outstanding options to purchase such
stock possessing five percent (5%) or more of the total combined voting power or
value of all classes of the capital stock of the Company or of any Parent,
Subsidiary, or (ii) to the extent his or her rights to purchase stock under all
employee stock purchase plans (as defined in Section 423(b) of the Code) of the
Company and any Parent or its subsidiaries will not accrue at a rate which
exceeds Twenty-Five Thousand Dollars ($25,000) worth of stock (determined at the
fair market value of the shares at the time such option is granted) for each
calendar year in which such option is outstanding at any time. The accrual of
rights to purchase stock shall be determined in accordance with Section
423(b)(8) of the Code.

         4.       Offering Periods. The Plan shall be implemented by consecutive
Offering Periods. The first Offering Period shall commence on the first Trading
Day following June 1, 1997 and shall terminate on the last Trading Day of the
sixth month following the commencement of the Offering Period. Thereafter,
Offering Periods shall commence on the first Trading Day following Exercise Date

office not later than one day prior to the applicable Enrollment Date.

the Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.


                                       3
<PAGE>   4
         6.       Payroll Deductions.

                  (a) At the time a participant files his or her enrollment
agreement, he or she shall elect to have payroll deductions made on each pay day
during an Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering
Period.

                  (b) All payroll deductions made for a participant shall be
credited to his or her account under the Plan and will be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

                  (c) A participant may discontinue his or her participation in
the Plan as provided in Section 10 hereof, but may not otherwise increase or
decrease the rate of his or her payroll deductions during the Offering Period. A
participant's enrollment agreement shall remain in effect for successive
Offering Periods unless terminated as provided in Section 10 hereof.

                  (d) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a
participant's payroll deductions may be decreased to 0% at such time during any
Offering Period which is scheduled to end during the current calendar year (the
"Current Offering Period") that the aggregate of all payroll deductions which
were previously used to purchase stock under the Plan in a prior Offering Period
which ended during that calendar year plus all payroll deductions accumulated
with respect to the Current Offering Period equal $21,250. Payroll deductions
shall recommence at the rate provided in such participant's enrollment agreement
at the beginning of the first Offering Period which is scheduled to end in the
following calendar year, unless terminated by the participant as provided in
Section 10 hereof.

                  (e) At the time the option is exercised, in whole or in part,
or at the time some or all of the Company's Common Stock issued under the Plan
is disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but will not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

         7.       Grant of Option. On the Enrollment Date of each Offering
Period, each eligible Employee participating in such Offering Period shall be
granted an option to purchase on the Exercise Date of such Offering Period (at
the applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the participant's account as of the
Exercise Date by the applicable Purchase Price. During a six month Offering
Period no Employee shall be permitted to purchase, more than 2,000 shares (or
such lesser number determined by the Administrator); provided, however, that
such limit shall be adjusted proportionately in the event of an Offering Period
longer than six months. All such purchases shall also be subject to the
limitations set forth in Sections 3(b) and 12 hereof. Exercise of the option
shall occur as provided  


                                       4
<PAGE>   5
in Section 8 hereof, unless the participant has withdrawn pursuant to Section 10
hereof, and shall expire on the last day of the Offering Period.

         8.       Exercise of Option. Unless a participant withdraws from the
Plan as provided in Section 10 hereof, his or her option for the purchase of
shares shall be exercised automatically on the Exercise Date, and the maximum
number of full shares subject to option shall be purchased for such participant
at the applicable Purchase Price with the accumulated payroll deductions in his
or her account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be carried over in the participant's account into the next
Offering Period. During a participant's lifetime, a participant's option to
purchase shares hereunder is exercisable only by him or her.

         9.       Delivery. As promptly as practicable after each Exercise Date
on which a purchase of shares occurs, the shares shall be credited to an account
in the participant's name with a brokerage firm selected by the Plan Committee
to hold the shares in it's street name.

         10.      Withdrawal; Termination of Employment.

                  (a) A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time up to two weeks prior to any
Exercise Date by giving written notice to the Company in the form of Exhibit B
to this Plan. All of the participant's payroll deductions credited to his or her
account will be paid to such participant promptly after receipt of notice of
withdrawal, such participant's option for the Offering Period will be
automatically terminated, and no further payroll deductions for the purchase of
shares will be made during the Offering Period. If a participant withdraws from
an Offering Period, payroll deductions will not resume at the beginning of the
succeeding Offering Period unless the participant delivers to the Company a new
enrollment agreement.

                  (b) Upon a participant's ceasing to be an Employee (as defined
in Section 2(g) hereof) for any reason, he or she will be deemed to have elected
to withdraw from the Plan and the payroll deductions credited to such
participant's account during the Offering Period but not yet used to exercise
the option will be returned to such participant or, in the case of his or her
death, to the person or persons entitled thereto under Section 14 hereof, and
such participant's option will be automatically terminated. The preceding
sentence notwithstanding, a participant who receives payment in lieu of notice
of termination of employment shall be treated as continuing to be an Employee
for the participant's customary number of hours per week of employment during
the period in which the participant is subject to such payment in lieu of
notice.

                  (c) A participant's withdrawal from an Offering Period will
not have any effect upon his or her eligibility to participate in any similar
plan which may hereafter be adopted by the Company or in succeeding Offering
Periods which commence after the termination of the Offering Period from which
the participant withdraws.

         11.      Interest. No interest shall accrue on the payroll deductions
of a participant in the Plan.


                                       5
<PAGE>   6
         12.      Stock.

                  (a) The maximum number of shares of the Company's Common Stock
which shall be made available for sale under the Plan shall be three hundred
fifty thousand (350,000) shares, subject to adjustment upon changes in
capitalization of the Company as provided in Section 18 hereof. Shares issuable
under the Plan shall be Treasury Shares. If on a given Exercise Date the number
of shares with respect to which options are to be exercised exceeds the number
of shares then available under the Plan, the Company shall make a pro rata
allocation of the shares remaining available for purchase in as uniform a manner
as shall be practicable and as it shall determine to be equitable.


                  (b) The participant will have no interest or voting right in
shares covered by his option until such option has been exercised.

                  (c) Shares to be delivered to a participant under the Plan
will be registered in the name of the participant or in the name of the
participant and his or her spouse.

         13.      Administration.

                  (a) Administrative Body. The Plan shall be administered by the
Board or a committee of members of the Board appointed by the Board. The Board
or its committee shall have full and exclusive discretionary authority to
construe, interpret and apply the terms of the Plan, to determine eligibility
and to adjudicate all disputed claims filed under the Plan. Every finding,
decision and determination made by the Board or its committee shall, to the full
extent permitted by law, be final and binding upon all parties.

                  (b) Rule 16b-3 Limitations. Notwithstanding the provisions of
Subsection (a) of this Section 13, in the event that Rule 16b-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or
any successor provision ("Rule 16b-3") provides specific requirements for the
administrators of plans of this type, the Plan shall be administered only by
such a body and in such a manner as shall comply with the applicable
requirements of Rule 16b-3.

         14.      Designation of Beneficiary.

                  (a) A participant may file a written designation of a
beneficiary who is to receive any shares and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to an Exercise Date on which the option is exercised but prior to
delivery to such participant of such shares and cash. In addition, a participant
may file a written designation of a beneficiary who is to receive any cash from
the participant's account under the Plan in the event of such participant's
death prior to exercise of the option. If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.


                                       6
<PAGE>   7
                  (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

         15.      Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 14 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof. Shares of
Common Stock acquired through exercise of options granted pursuant to this Plan
may not be sold or otherwise transferred until at least twelve months after the
Exercise Date. The Company shall have the right to place a legend on all stock
certificates delivered pursuant to this Plan setting forth the restriction on
transferability of such shares.

         16.      Use of Funds. All payroll deductions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

         17.      Reports. Individual accounts will be maintained for each
participant in the Plan. Statements of account will be given to participating
Employees at least annually, which statements will set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

         18.      Adjustments Upon Changes in Capitalization; Dissolution;
Liquidation; Merger or Asset Sale.

                  (a) Changes in Capitalization. Subject to any required action
by the stockholders of the Company, the Reserves as well as the price per share
of Common Stock covered by each option under the Plan which has not yet been
exercised, 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 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 Board, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issuance by the
Company of shares of 


                                       7
<PAGE>   8
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) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

                  (c) Merger or Asset Sale. 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 Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"). The
New Exercise Date shall be before the date of the Company's proposed sale or
merger. The Board shall notify each participant in writing, at least ten (10)
business days prior to the New Exercise Date, that the Exercise Date for the
participant's option has been changed to the New Exercise Date, unless prior to
such date the participant has withdrawn from the Offering Period as provided in
Section 10 hereof.

         19.      Amendment or Termination.

                  (a) The Board of Directors of the Company may at any time and
for any reason amend or terminate the Plan. Except as provided in Section 18
hereof, no such termination can affect options previously granted. Except as
provided in Section 18 hereof, no amendment may make any change in any option
theretofore granted which adversely affects the rights of any participant. To
the extent necessary to comply with Rule 16b-3 or under Section 423 of the Code
(or any successor rule or provision or any other applicable law or regulation),
the Company shall obtain shareholder approval in such a manner and to such a
degree as required.

                  (b) Without shareholder consent and without regard to whether
any participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods
(provided no Offering Period may be more than seven months), limit the frequency
and/or number of changes in the amount withheld during an Offering Period,
establish the exchange ratio applicable to amounts withheld in a currency other
than U.S. dollars, permit payroll withholding in excess of the amount designated
by a participant in order to adjust for delays or mistakes in the Company's
processing of properly completed withholding elections, establish reasonable
waiting and adjustment periods and/or accounting and crediting procedures to
ensure that amounts applied toward the purchase of Common Stock for each
participant properly correspond with amounts withheld from the participant's
Compensation, and establish such other limitations or procedures as the Board
(or its committee) determines in its sole discretion advisable which are
consistent with the Plan.

         20.      Notices. All notices or other communications by a participant
to the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.

         21.      Conditions Upon Issuance of Shares. Shares shall not be 
issued with respect to an option unless the exercise of such option and the 
issuance and delivery of such shares pursuant 


                                       8
<PAGE>   9
thereto shall comply with all applicable provisions of law, domestic or foreign,
including, without limitation, the Securities Act of 1933, as amended, the
Securities Exchange Act of 1934, as amended, 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 applicable provisions of law.

         22. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 19 hereof.

                          DOCUMENT SCIENCES CORPORATION

                        1997 EMPLOYEE STOCK PURCHASE PLAN

                              ENROLLMENT AGREEMENT


_____ Original Application                          Enrollment Date: __________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)

1.       _____________________________________ hereby elects to participate in
         the Document Sciences Corporation 1997 Employee Stock Purchase Plan
         (the "Employee Stock Purchase Plan") and subscribes to purchase shares
         of the Company' s Common Stock in accordance with this Enrollment
         Agreement and the Employee Stock Purchase Plan.

2.       I hereby authorize payroll deductions from each paycheck in the amount
         of ____% of my Gross Compensation (not to exceed 10%) beginning on the
         first payday after the Grant Date and on each payday thereafter until
         the Exercise Date, as determined by the Board, in accordance with the
         Employee Stock Purchase Plan. (Please note that no fractional
         percentages are permitted.)

3.       I understand that said payroll deductions shall be accumulated for the
         purchase of shares of Company's Common Stock at the applicable Purchase
         Price determined in accordance with the Section 9.3 of the Employee
         Stock Purchase Plan. I understand that, prior to the Exercise Date, I
         shall be permitted only once to (a) withdraw accumulated payroll
         deductions, (b) discontinue payroll deductions, or (c) decrease, but
         not increase, the percentage of Gross Compensation withheld. I further
         understand that I may withdraw all but not less than all the payroll
         deductions credited to my account and not yet used to exercise my
         option under the Plan at any time up to two weeks prior to the Exercise
         Date by giving written notice to the Company.

4.       I have received a copy of the complete "Employee Stock Purchase Plan."
         I understand that my participation in the Employee Stock Purchase Plan
         is in all respects subject to the terms of the Plan. I understand that
         the grant of the option by the Company under this Enrollment Agreement
         is subject to obtaining shareholder approval of the Employee Stock
         Purchase Plan.

5.       Shares purchased for me under the Employee Stock Purchase Plan should
         be issued in the name(s) of (Employee or Employee and Spouse Only):


                                       1
<PAGE>   11
6.       I understand that I may not sell or otherwise transfer shares of Common
         Stock purchased pursuant to this Plan until at least twelve months
         after the Exercise Date and that the Company shall have the right to
         place a legend on all stock certificates representing Option Shares
         setting forth the restriction on transferability of such shares.

7.       I understand that if I dispose of any shares received by me pursuant to
         the Plan within 2 years after the Enrollment Date (the first day of the
         Offering Period during which I purchased such shares), I will be
         treated for federal income tax purposes as having received ordinary
         income at the time of such disposition in an amount equal to the excess
         of the fair market value of the shares at the time such shares were
         purchased by me over the price which I paid for the shares. I hereby
         agree to notify the Company in writing within 30 days after the date of
         any disposition of shares and I will make adequate provision for
         Federal, state or other tax withholding obligations, if any, which
         arise upon the disposition of the Common Stock. The Company may, but
         will not be obligated to, withhold from my compensation the amount
         necessary to meet any applicable withholding obligation including any
         withholding necessary to make available to the Company any tax
         deductions or benefits attributable to sale or early disposition of
         Common Stock by me. If I dispose of such shares at any time after the
         expiration of the 2-year holding period, I understand that I will be
         treated for federal income tax purposes as having received income only
         at the time of such disposition, and that such income will be taxed as
         ordinary income only to the extent of an amount equal to the lesser of
         (1) the excess of the fair market value of the shares at the time of
         such disposition over the purchase price which I paid for the shares,
         or (2) 15% of the fair market value of the shares on the first day of
         the Offering Period. The remainder of the gain, if any, recognized on
         such disposition will be taxed as capital gain.

8.       I hereby agree to be bound by the terms of the Employee Stock Purchase
         Plan. The effectiveness of this Enrollment Agreement is dependent upon
         my eligibility to participate in the Employee Stock Purchase Plan.

9.       In the event of my death, I hereby designate the following as my
         beneficiary(ies) to receive all payments and shares due me under the
         Employee Stock Purchase Plan:
