                                    SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and financial statements appearing elsewhere in this Prospectus.
See "Risk Factors" for a discussion of certain factors to be considered by
prospective investors.
 
                                  THE COMPANY
 
  Visigenic Software, Inc. ("Visigenic" or the "Company") is a leading provider
of software tools for database and distributed object connectivity for the
Internet, Intranet and enterprise computing environments. The Company's
standards-based products facilitate the development, deployment and management
of distributed applications by providing database-independent access to leading
databases and the communications infrastructure for distributed object-oriented
applications.
 
  In today's complex computing environment, enterprises require flexible access
to data and applications, regardless of whether the data and applications are
located at the central office, a remote office or across the Internet.
Enterprise computing environments are increasingly using multiple database
management systems ("DBMSs"), operating systems, networks and hardware
platforms and relying on object-oriented technologies to develop and deploy
distributed applications for these heterogeneous environments. The rapid growth
of the Internet and Intranets, both of which are heterogeneous distributed
computing environments, is accelerating the need for tools to develop, deploy
and manage distributed applications.
 
  The Visigenic solution provides key components of the software infrastructure
that enables developers and information technology ("IT") professionals to
develop, deploy and manage distributed applications. The Company believes
business applications increasingly will be comprised of objects, Java applets
and databases that are distributed on networks and dynamically assembled into
highly customized distributed solutions. The Company's products enable the
enterprise to adapt its application architecture to meet changing business and
computing requirements by simplifying the development and deployment of
distributed database and object-oriented applications. Visigenic's products
support existing and emerging industry standards, making the Company's
solutions open, flexible and interoperable across multiple operating
environments. The Company believes that its products are especially well suited
for large distributed computing environments such as the Internet and
Intranets.
 
  The Company's strategy is to become the premier provider of software tools
which enable developers and IT professionals to develop, deploy and manage
distributed applications for Internet, Intranet and enterprise computing
environments. Visigenic supports and contributes to the enhancement of open
industry standards through active participation in several standards setting
organizations. The Company intends to continue to develop strategic
relationships with leading technology companies to promote the widespread
acceptance and distribution of Visigenic products. Visigenic has established
strategic relationships with Cisco, Hitachi, Microsoft, Netscape and Platinum
technology. Additionally, the Company intends to leverage its products and
expertise to exploit the emergence of the Internet and Intranets.
 
  The Company markets and sells its software through its direct sales and
telesales forces, independent software vendors ("ISVs"), value added resellers
("VARs"), international distributors and on-line Internet sales in North
America, Europe and Asia. The Company's customers include ASCII Corporation,
Cisco, Compuware, Borland, Healtheon, Hewlett-Packard, Hitachi, Merrill Lynch,
MCI Telecommunications, Microsoft, Netscape, Oracle, Platinum technology and
Software AG.
   
  In May 1996, the Company acquired PostModern Computing Technologies, Inc.
("PostModern"), a supplier of distributed object connectivity software.
PostModern had revenue of $1.0 million and net income of     
 
                                       3
<PAGE>
 
   
$58,849 in the year ended March 31, 1996, and had total assets of $473,771 at
March 31, 1996. In the acquisition, which was structured as a merger, the
Company issued 3,099,821 shares of its Common Stock and paid a total of $2.3
million in exchange for all PostModern shares. The Company also assumed
PostModern's outstanding stock options and made cash payments, subject to one-
year vesting, totaling $1.5 million, to certain PostModern employees. A portion
of the proceeds from the Company's issuance of its Series C Preferred Stock and
convertible notes to three investors in May 1996 was used to finance the cash
portion of the acquisition.     
 
  The Company was incorporated in February 1993. The Company's principal
executive offices are located at 951 Mariner's Island Boulevard, Suite 120, San
Mateo, California, 94404. Its telephone number is (415) 286-1900. Its email
address is [email protected] and its World Wide Web site is located at

                                 RISK FACTORS
 
  The following risk factors should be considered carefully in addition to the
other information contained in this Prospectus before purchasing the Common
Stock offered hereby. This Prospectus 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 risk factors set forth below and elsewhere in this Prospectus.
 
  Limited Operating History; History of Losses; Recent Acquisition of
Distributed Object Connectivity Business. The Company was incorporated in 1993
and commenced shipment of its initial products in November 1994. In May 1996,
the Company acquired PostModern Computing Technologies Inc. ("PostModern"), a
developer of distributed object connectivity software. PostModern was founded
in 1991, commenced shipment of its initial products in 1992 and had very
limited product sales prior to the acquisition. Accordingly, the Company has
only a limited operating history, particularly with respect to its newly
acquired distributed object connectivity business, upon which an evaluation of
the Company and its future operating results can be based.
 
  Since inception, the Company has incurred significant losses and negative
cash flow. At June 30, 1996, the Company had cumulative operating losses of
$25.1 million, with net losses of $2.5 million, $4.6 million, $4.4 million and
$13.7 milion for fiscal 1994, fiscal 1995, fiscal 1996 and the quarter ended
June 30, 1996, respectively. A substantial portion of the accumulated deficit
is due to the significant commitment of resources to the Company's product
development and sales and marketing activities and the write-off of
approximately $12.0 million of in process product development in the quarter
ended June 30, 1996 in connection with the acquisition of PostModern. The
Company expects to continue to devote substantial resources in these areas and
as a result will need to generate significant revenue in order to achieve
profitability. The Company currently anticipates that it will operate at a
loss through at least the middle of 1997. The Company has experienced
substantial growth in revenue in fiscal 1996. The Company expects that prior
growth rates of the Company's software product revenue will not be sustainable
in the future. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
  The Company, which prior to the acquisition of PostModern did not provide
distributed object connectivity software, expects that its revenue growth
commencing in the current fiscal year will be dependent, in part, on sales of
distributed object connectivity products. The Company's ability to develop a
distributed object connectivity software business will depend upon several
factors, including, but not limited to, its ability to integrate the
operations and personnel of PostModern into the Company, the ability of the
Company's sales personnel and distribution channels to sell distributed object
connectivity software and the commercial acceptance of the Company's
distributed object connectivity software. Because the market for distributed
object technology is new and emerging and customers' expertise about this
technology is limited, the Company believes that customer support is critical
to achieving sales of the Company's distributed object connectivity products.
The Company currently has few dedicated support engineers capable of providing
the required level of customer support with respect to its distributed object
technology business. If the Company is unsuccessful at attracting additional
support and engineering personnel, this is likely to have a material adverse
effect on the Company's distributed object connectivity business. There can be
no assurance, particularly in light of the recent acquisition of PostModern by
the Company and the limited operating history of PostModern itself, that the
Company's distributed object connectivity software business will be
successful. Any failure by the Company to develop a successful distributed
object connectivity software business would have a material adverse effect on
the Company's business, results of operations and financial condition.
 
  The process of integrating PostModern into the Company may result in
unforeseen operating difficulties and expenditures and may absorb significant
management attention that would otherwise be available for ongoing development
of the Company's business. Moreover, there can be no assurance that the
anticipated benefits of this acquisition will be realized.
 
  Potential Fluctuations in Operating Results. The Company's revenue and
results of operations have varied on a quarterly basis in the past and are
expected to vary significantly in the future. Accordingly, the Company
 
                                       6
<PAGE>
 
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. The Company's revenue and results of operations are
difficult to forecast and could be adversely affected by many factors,
including, among others, the size, timing and terms of individual license
transactions; the relatively long sales and implementation cycles for the
Company's products; the delay or deferral of customer implementations; changes
in the Company's operating expenses; the ability of the Company to develop and
market new products and control costs; market acceptance of new products;
timing of introduction or enhancement of products by the Company or its
competitors; the level of product and price competition; the ability of the
Company to expand its direct sales and telesales forces, its indirect
distribution channels and its customer support capabilities; activities of and
acquisitions by competitors; changes in connectivity software, database
technology and industry standards; changes in the mix of products and services
sold; changes in the mix of channels through which products and services are
sold; levels of international sales; personnel changes and difficulties in
attracting and retaining qualified sales, marketing and technical personnel;
changes in customers' budgeting cycles; foreign currency exchange rates;
quality control of products sold; and general economic conditions. In
particular, the ability of the Company to achieve revenue growth in the future
will depend on its success in adding a substantial number of sales and sales
support personnel in fiscal 1997. Competition for such personnel is intense
and there can be no assurance the Company will be able to attract and retain
these personnel.
 
  Licensing of the Company's software products historically has accounted for
the substantial majority of the Company's revenue, and the Company anticipates
that this trend will continue for the foreseeable future. The Company's
software products revenue is difficult to forecast for a number of reasons.
The Company typically does not have a material backlog of unfilled orders, and
revenue in any quarter is substantially dependent on contracts received in
that quarter. A significant portion of the Company's revenue in prior periods
has been derived from relatively large sales to a limited number of customers,
and the Company currently anticipates that future quarters will continue to
reflect this trend. In fiscal 1996, approximately 78% of the Company's revenue
was derived from ten customers and revenue from one customer, Platinum
technology, Inc., accounted for approximately 25% of the Company's total
revenue. For the quarter ended June 30, 1996, approximately 75% of the
Company's revenue was derived from ten customers, and revenue from one
customer, Cisco Systems, Inc., accounted for approximately 34% of the
Company's total revenue. Sales cycles for the Company's products typically
range from six to twelve months, and the terms and conditions of individual
license transactions, including prices and discounts, are often highly
negotiated based on volumes and commitments and vary considerably from
customer to customer. In addition, the Company has generally recognized a
substantial portion of its revenue in the last month of each quarter, with
this revenue concentrated in the last weeks of the quarter. Accordingly, the
cancellation or deferral of even a small number of purchases of the Company's
products has in the past and could in the future have a material adverse
effect on the Company's business, results of operations and financial
condition in any particular quarter. Cancellations or deferrals of orders may
be caused by any of a number of factors, including delays in new or enhanced
product shipments. To the extent that significant sales occur earlier than
expected, operating results for subsequent quarters may be adversely affected.
A significant portion of the Company's revenue has been and is expected in the
future to continue to be based upon sales to third party vendors, who will
incorporate the Company's products in their own products. This revenue depends
upon the success of third parties, and as a result is difficult for the
Company to predict and may be subject to extreme fluctuation.
 
  The Company's expense levels are based, in part, on its expectations as to
future revenue and to a large extent are fixed in the short term. The Company
may be unable to adjust spending in a timely manner to compensate for any
unexpected revenue shortfall. Accordingly, any significant shortfall of
revenue in relation to the Company's expectations would have an almost
immediate adverse effect on the Company's business, financial condition and
results of operations. Further, the Company intends to continue to expand its
development teams and its sales and marketing force. The timing of such
expansion and the rate at which new development and sales and marketing
personnel become productive could cause material fluctuations in quarterly
results of operations.
 
                                       7
<PAGE>
 
  As a result of the foregoing or other factors, it is likely that in some
future period the Company's results of operations will fail to meet the
expectations of public market analysts or investors, and the price of the
Company's Common Stock would likely be materially adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
  Product Concentration. Prior to the acquisition of PostModern in May 1996,
the Company derived all of its revenue from the licensing of its database
connectivity software products, particularly its Open Database Connectivity
("ODBC") product line, and fees from related services. These products and
services are expected to continue to account for a substantial majority of the
Company's revenue for the foreseeable future. As a result, a reduction in
demand or increase in competition for these products, or a decline in sales of
such products, would have a material adverse effect on the Company's business,
results of operations and financial condition. See "Business--Products."
 
  Dependence on Emerging Markets and Evolving Standards; Acceptance of the
Company's Products. The Company's future financial performance will depend on
the growth in demand for standards-based database connectivity and distributed
object connectivity software products. These markets are new and emerging, are
rapidly evolving, are characterized by an increasing number of market entrants
and will be subject to frequent and continuing changes in customers'
preferences and technology. As is typical in new and evolving markets, demand
and market acceptance for products are subject to a high level of uncertainty.
 
  To date, substantially all of the Company's revenue is derived from the
licensing of database connectivity products and fees for related services.
These products are based on the ODBC standard, which was developed to enable
applications to access data from all ODBC-compliant data sources. While the
ODBC standard is supported by most of the major database and software vendors,
it is a recent standard that has not yet gained widespread acceptance and that
currently co-exists with proprietary database connectivity solutions from many
of these same database and software vendors.
 
  With the acquisition of PostModern in May 1996, the Company began to offer
standards-based distributed object connectivity products. The Company's
current distributed object connectivity products are based on several
standards, including the Common Object Request Broker Architecture ("CORBA")
and the Internet Inter-ORB Protocol ("IIOP"). These standards are intended to
facilitate the management and communication of applications created in object-
oriented programming languages such as C++ and Java. These standards are new,
have not yet gained widespread acceptance and compete with proprietary
solutions such as Microsoft's ActiveX and Distributed Component Object Model
("DCOM"). The distributed object connectivity software market is relatively
young and there are few proven products. Further, some of the Company's
distributed object connectivity products are designed specifically for use in
applications for the Internet and Intranets. Because critical issues
concerning the Internet and Intranets -- including security, reliability,
cost, ease of use and access and quality of service -- remain unresolved, the
growth of applications targeted at the Internet and Intranets is uncertain and
difficult to predict.
 
  Because the markets for the Company's products are new and evolving, it is
difficult to assess or predict with any assurance the size or growth rate, if
any, of these markets. There can be no assurance that the markets for the
Company's products will develop, or that the Company's products will be
adopted. If these markets fail to develop, develop more slowly than expected
or attract new competitors, or if the Company's products do not achieve market
acceptance, the Company's business, results of operations and financial
condition could be materially adversely affected. Because the Company's
strategy is to develop standards-based products and these standards are
relatively new, not widely accepted and compete with other emerging standards,
to the extent that these standards are not commercially successful, this will
have a material adverse affect on the Company's business, results of
operations and financial condition. Competing or alternative technologies are
being or are likely in the future to be promoted by current and potential
competitors of the Company, some of which have well-established relationships
with the current and potential customers of the Company and have extensive
knowledge of the markets served by the Company, better name recognition and
more extensive development, sales and marketing resources than the Company.
 
                                       8
<PAGE>
 
  While the Company has licensed its products to numerous customers, most of
these customers are currently developing applications that incorporate the
Company's products, and only a very limited number of them have deployed or
shipped such applications. To the extent these customers are unable to or
otherwise do not deploy or ship applications that incorporate the Company's
products, or if these applications are not successful, this will have a
material adverse effect on the Company's business, results of operations and
financial condition. See "--Intense Competition" and "Business--Industry
Background."
   
  Reliance on VARs and ISVs. A significant element of the Company's strategy
is to embed its technology in products offered by the Company's VAR and ISV
customers, such as Cisco, Healtheon, Hewlett-Packard, Microsoft, Netscape,
Oracle and Platinum technology. A relatively small number of VAR and ISV
customers have accounted for a significant percentage of the Company's
revenue. In fiscal 1996, ten VAR and ISV customers accounted for approximately
78% of the Company's revenue, while in the first quarter of fiscal 1997, ten
VAR and ISV customers accounted for approximately 75% of the Company's
revenue. The Company intends to seek similar distribution arrangements with
other VARs and ISVs to embed the Company's technology in their products and
expects that these arrangements will account for a significant portion of the
Company's revenue in future periods. To date, the terms and conditions,
including prices and discounts, of the Company's agreements with its VAR and
ISV customers have been highly negotiated and vary significantly between
customers, however, all of these agreements are non-exclusive and do not
require the VAR or ISV to make minimum purchases. Many of the markets for the
VAR and ISV products in which the Company's technology are being embedded are
new and evolving and, therefore, subject to the same risks faced by the
Company in the markets for its own products. If the Company is unsuccessful in
securing license agreements with additional VARs and ISVs on commercially
reasonable terms or at all, or if the Company's VAR and ISV customers are
unsuccessful in selling their products, this would have a material adverse
effect on the Company's business, results of operations and financial
condition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."     
 
  Dependence on the Internet and Intranets. The Company believes that sales of
its connectivity products, particularly its distributed object connectivity
products, will depend in large part upon the adoption by businesses and end-
users of the Internet and Intranets for commerce and communications. The
Internet and Intranets are new and evolving, and there can be no assurance of
their widespread adoption. Critical issues concerning the Internet and
Intranets, including security, reliability, cost, ease of use and access and
quality of service, remain unresolved at this time, inhibiting adoption by
many enterprises and end-users. If the Internet and Intranets are not widely
used by businesses and end-users, this will have a material adverse effect on
the Company's business, results of operations and financial condition.
 
  Dependence on Java; Risks Associated with Encryption Technology. Certain of
the Company's products are based on Java, an object-oriented programming
language developed by JavaSoft, a subsidiary of Sun Microsystems. Java was
developed primarily for Internet and Intranet applications. Java was only
recently introduced and does not yet have sufficient history to establish its
reliability, thereby inhibiting adoption of Java. To date, there have been
only a very limited number of commercially significant Java-based products,
and it is too early to determine whether Java will become a significant
technology. Alternatives to Java have been announced by several companies,
including Microsoft. To the extent that Java is not adopted or is adopted more
slowly than anticipated, this could have a material adverse effect on the
Company's business, results of operations and financial condition.
 
  The Company plans to use encryption technology in certain of its future
products to provide the security required for the exchange of confidential
information. Encryption technologies have been breached in the past. There can
be no assurance that there will not be a compromise or breach of the security
technology used by the Company. If any such compromise or breach were to
occur, it could have a material adverse effect on the Company's business,
results of operations and financial condition.
 
  Need to Develop New Software Products and Enhancements. The markets for the
Company's products are characterized by rapid technological developments,
evolving industry standards, swift changes in customer
 
                                       9
<PAGE>
 
requirements, computer operating environments and software applications, and
frequent new product introductions and enhancements. As a result, the
Company's success depends substantially upon its ability to anticipate changes
and continue to enhance its existing products, develop and introduce in a
timely manner new products incorporating technological advances, comply with
emerging industry standards and meet increasing customer expectations. The
Company's products may be rendered obsolete if the Company fails to anticipate
or react to change. To the extent one or more of the Company's competitors
introduce products that better address customer needs, the Company's business,
results of operations and financial condition could be materially adversely
affected. There can be no assurance that the Company will be successful in
developing and marketing new products or enhancements to its existing products
on a timely basis or at all or that any new or enhanced products will
adequately address the changing needs of the marketplace. The Company has in
the past incurred product development expenses and sales and marketing
expenses in connection with product development activities that did not result
in commercially introduced products. Some of the Company's products are based
on technology from third parties and the Company therefore has limited control
over whether and when these technologies are enhanced. For instance, the
VisiODBC Software Developers Kit ("SDK") products are based upon ODBC software
licensed from Microsoft. The failure or delay in enhancements of technology
from third parties used in the Company's products could have a material
adverse effect on the Company's ability to develop and enhance its own
products. Also, negative reviews of the Company's new products or product
versions in industry publications could have a material adverse effect on the
Company's sales. The Company has in the past experienced delays in the
development of new products and product versions. If the Company is unable to
develop and introduce new products or enhancements to existing products in a
timely manner in response to changing market conditions or customer
requirements, the Company's business, results of operations and financial
condition would be materially and adversely affected.
 
  The Company has in the past engaged and expects that it will continue in the
future to engage in joint development projects with third parties. Currently,
the Company is engaged in joint development with Hitachi of distributed object
connectivity software targeted at transaction processing applications. Joint
development creates several risks for the Company, including loss of control
over the development of aspects of the jointly developed product and over the
timing of product availability. There can be no assurance that joint
development activities will result in products, or that any products developed
will be commercially successful.
   
  Dependence on Key Personnel; Need to Increase Technical, Sales and Marketing
and Managerial Personnel. The Company's future performance depends to a
significant extent upon the continued service of its key technical, sales and
marketing and senior management personnel. The loss of the services of any of
these individuals would have a material adverse effect on the Company. All
employees are employed at-will, and the Company has no fixed term employment
agreements with any of its employees. The Company's future success also
depends on its continuing ability to attract, train and retain highly
qualified technical, sales and marketing and managerial personnel. In
particular, the Company currently has a very limited technical staff devoted
to its distributed object connectivity business. An increase in the technical
staff will be required to rapidly develop the database connectivity and
distributed object connectivity products currently being planned, while an
increase in the sales and marketing staff will be required to expand both the
Company's direct and indirect sales activities and achieve revenue growth. The
Company intends to hire a significant number of additional technical and sales
and marketing personnel in fiscal 1997 and beyond. Competition for such
personnel is intense, and there can be no assurance that the Company can
attract, assimilate or retain such personnel. Because of the complexity of
database connectivity and distributed object connectivity software products,
the Company has in the past experienced and expects to continue in the future
to experience a time lag between the date technical and sales personnel are
hired and the date such persons become fully productive. If the Company is
unable to hire and train such personnel on a timely basis in the future, the
Company's business, results of operations and financial condition could be
materially adversely affected.     
 
  Management of Growth; Need to Increase Financial Personnel and Implement
Policies. The Company's business has grown rapidly in recent periods, with
revenue increasing from $1.1 million in fiscal 1995 to $5.6 million in fiscal
1996. In addition, the Company acquired PostModern in May 1996 as part of its
strategy of
 
                                      10
<PAGE>
 
adding distributed object connectivity products to its product line. The
growth of the Company's business, the expansion of the Company's customer base
and the recent acquisition and integration of PostModern have placed a
significant strain on the Company's management, operations and financial
systems, policies and procedures. The Company's recent expansion has also
resulted in substantial growth in the number of its employees, the scope of
its operating and financial systems and the geographic area of its operations,
resulting in increased responsibility for management personnel. The Company's
future results of operations will depend in part on the ability of its
officers and other key employees to continue to implement its operational,
customer support and financial control systems and to expand, train and manage
its employee base. The Company hired a new Chief Financial Officer and a new
controller in July 1996. The Company's current financial systems, policies and
procedures are limited. The Company is in the process of developing a more
comprehensive set of written financial policies and procedures to supplement
its limited current policies and procedures and still must hire additional
accounting staff experienced in the software industry. There can be no
assurance that the Company will be able to manage any future expansion of its
business, if any, successfully, or that its management, personnel, procedures
and systems will be adequate to support the Company's operations. Any such
inabilities or inadequacies to do so would have a material adverse effect on
the Company's business, results of operations and financial condition.
 
  Potential Acquisitions. If appropriate opportunities present themselves, the
Company intends to acquire businesses, products or technology that the Company
believes are strategic, although the Company currently has no understandings,
commitments or agreements with respect to any material acquisition and no
material acquisition is currently being pursued. There can be no assurance
that the Company will be able to successfully identify, negotiate or finance
such acquisitions, or to integrate such acquisitions with its current
business. The process of integrating an acquired business, product or
technology into the Company may result in unforeseen operating difficulties
and expenditures and may absorb significant management attention that would
otherwise be available for ongoing development of the Company's business.
Moreover, there can be no assurance that the anticipated benefits of any
acquisition will be realized. Acquisitions could result in potentially
dilutive issuances of equity securities, the incurrence of debt and contingent
liabilities and amortization expenses related to goodwill and other intangible
assets, which could materially adversely affect the Company's business,
results of operations and financial condition. Any such future growth and any
acquisitions of other technologies, products or companies may require the
Company to obtain additional equity or debt financing, which may not be
available or may be dilutive.
 
  Intense Competition. The Company's products are targeted at the emerging
markets for standards-based database connectivity software and standards-based
distributed object connectivity software. The markets for the Company's
products are intensely competitive, subject to rapid change and significantly
affected by new product introductions and other market activities of industry
participants. The Company believes that the principal competitive factors in
these markets are product quality, performance and price, vendor and product
reputation, product architecture and quality of support.
 
  In the standards-based database connectivity market, the Company competes
principally against Intersolv. The Company's database connectivity products
also indirectly compete against proprietary database connectivity solutions
from database vendors. In the standards-based distributed object connectivity
market, the Company competes principally against two private companies, Iona
and Expersoft. The Company's distributed object connectivity products also
compete against existing or proposed distributed object connectivity solutions
from hardware vendors such as DEC, Hewlett-Packard, IBM and Sun. In addition,
because there are relatively low barriers to entry in the software market and
because the Company's products are based on publicly available standards, the
Company expects to experience additional competition in the future from other
established and emerging companies if the market for database connectivity and
distributed object connectivity software continues to develop and expand. In
particular, relational database vendors including Informix, Microsoft, Oracle
and Sybase may offer standards-based database connectivity software to their
customers, eliminating or reducing demand for the Company's products.
Similarly, operating system vendors such as DEC, Hewlett-Packard, IBM,
Microsoft and Sun may offer standards-based distributed object connectivity
products bundled with their
 
                                      11
<PAGE>
 
operating systems. For instance, Microsoft has announced plans to introduce
DCOM, which would eliminate the need for CORBA-compliant ORBs, such as those
offered by the Company, for Microsoft operating systems. Many of these current
and potential competitors have well-established relationships with the current
and potential customers of the Company, have extensive knowledge of the
markets serviced by the Company, better name recognition and more extensive
development, sales and marketing resources and are capable of offering single
vendor solutions. As a result, these current and potential competitors may be
able to respond more quickly to new or emerging technologies and changes in
customer requirements, or to devote greater resources to the development,
promotion and sale of their products, than the Company. It is also possible
that new competitors or alliances among competitors may emerge and rapidly
acquire significant market share. The Company also expects that competition
will increase as a result of software industry consolidations.
 
  The Company expects that it will face increasing pricing pressures from its
current competitors and new market entrants. Increased price competition may
result in price reductions, reduced gross margins and loss of market share,
any of which could materially adversely affect the Company's business,
financial condition or results of operations. There can be no assurance that
the Company will be able to compete successfully against current and future
competitors or that competitive pressures will not materially and adversely
affect its business, results of operations and financial condition. See
"Business--Competition."
 
  Risk of Product Defects. Software products as complex as those offered by
the Company frequently contain undetected errors or failures that may be
detected at any point in the product's life cycle. The Company has in the past
discovered software errors in certain of its new products and enhancements and
has experienced delays in shipment of products during the period required to
correct these errors. There can be no assurance that, despite testing by the
Company and potential customers, errors will not occur, resulting in loss of
or delay in market acceptance and sales, diversion of development resources,
injury to the Company's reputation or increased service and warranty costs,
any of which could have a material adverse effect on the Company's business,
results of operations and financial condition. This risk is amplified for the
Company because a significant portion of its future sales are expected to be
derived from arrangements under which third parties embed the Company's
products in their own products. Any significant errors in the Company's
products, or in the products of VARs or ISVs which embed the Company's
products, might discourage such third parties or other customers from
utilizing the Company's products, which would have a material adverse effect
on the Company's business, results of operations and financial condition.
Although the Company generally attempts to limit by contract its exposure to
incidental and consequential damages, and to cap the Company's liabilities to
its proceeds under a contract, if a court failed to enforce the liability
limiting provisions of the Company's contracts for any reason, or if
liabilities arose which were not effectively limited, the Company's business,
results of operations and financial condition could be materially and
adversely affected. See "Business--Product Development."
 
  Dependence on Company and Third Party Proprietary Technology. The Company's
success is dependent in part upon its proprietary technology. While the
Company relies on a combination of copyright and trademark laws, trade
secrets, confidentiality procedures and contractual provisions to protect its
proprietary rights, the Company believes that factors such as the technical
and creative skills of its personnel, new product developments, frequent
product enhancements, name recognition and reliable products and product
support are more essential to establishing and maintaining a technology
leadership position, particularly because the Company is supplying standards-
based products. The Company seeks to protect its software, published data,
documentation and other written materials under trade secret and copyright
laws, which afford only limited protection. The Company has granted limited
access to its source code to third parties under confidentiality obligations.
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
 
                                      12
<PAGE>
 
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
distributes its products electronically through the Internet. Distributing the
Company's products through the Internet makes the Company's software more
susceptible than other software to unauthorized copying and use. The Company
has historically allowed and currently intends to continue to allow, customers
to electronically download its client and server software. If as a result of
changing legal interpretations of liability for unauthorized use of the
Company's software or otherwise, users were to become less sensitive to
avoiding copyright infringement, the Company's business, results of operations
and financial condition could be materially adversely affected.
 
  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 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. 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, results of
operations and financial condition.
   
  In addition, the Company 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. The
Company licenses from Microsoft the base technology for the VisiODBC SDK
products and licenses from RSA Data Security, Inc. ("RSA") security technology
it plans to use in several of its future products. Microsoft has the right to
terminate its license with the Company at any time after delivery to the
Company of the Microsoft SDK for ODBC 3.0, which is expected to occur in the
second half of 1996. While certain licenses from Microsoft are granted to the
Company on an exclusive basis, Microsoft has the right to convert such
licenses to non-exclusive licenses. The Company's license with RSA may only be
terminated for breach. The Company has entered into a joint technology
agreement with JavaSoft, a subsidiary of Sun Microsystems, that grants the
Company the right to sublicense JavaSoft's Java database connectivity ("JDBC")
test suites and ODBC bridge. There can be no assurances that such firms will
remain in business, that they will continue to support their technology or
that their technology will otherwise continue to be available to the Company
on commercially reasonable terms. The loss of or inability to maintain any of
these software licenses could result in delays or cancellations in product
shipments until equivalent software can be identified and licensed or
developed and integrated with the Company's products. Any such delay or
cancellation could materially adversely affect the Company's business, results
of operations and financial condition. See "Business--Intellectual Property
and Other Proprietary Rights."     
 
  International Sales. The Company's export sales accounted for approximately
10% and 4% of the Company's total revenue in fiscal 1996 and the first quarter
of fiscal 1997, respectively. The Company had no material export sales in
fiscal 1994 or 1995. The Company expects to increase its emphasis on export
sales. Revenue derived from export sales may account for a growing percentage
of the Company's revenue in future periods, although there can be no assurance
that the Company will achieve significant penetration in any international
market. The Company has only one international sales office, which is located
in Paris, France. The Company believes that its continued growth will require
expansion of its international operations and export sales. To successfully
expand export sales, the Company must establish additional foreign sales
offices, hire additional personnel and recruit additional international
resellers. To the extent the Company is unable to do so in a timely manner,
the Company's growth in export sales, if any, will be limited, and the
Company's business, results of operations and financial condition could be
materially adversely affected. The Company has granted exclusive distribution
rights in Japan for the Japanese versions of its ODBC products to ASCII
Corporation, a Japanese software distributor. The Company may not terminate
these exclusive rights unless ASCII fails to meet
 
                                      13
<PAGE>
 
certain minimum annual sales objectives commencing in fiscal year 1998 or
otherwise breaches the agreement. There can be no assurance that ASCII will be
successful selling the Company's products.
 
  There are a number of risks inherent in the Company's international business
activities, including unexpected changes in regulatory requirements, tariffs
and other trade barriers, costs and risks of localizing and internationalizing
products for foreign countries, longer accounts receivable payment cycles,
potentially adverse tax consequences, repatriation of earnings and the burdens
of complying with a wide variety of foreign laws. None of the Company's
products is currently a "double byte" product, which is required to localize
these products in certain non-English character set markets such as Asia. The
Company believes that it will be required to develop double byte versions of
its products and engage in other internationalization and localization
activities. There can be no assurance the Company will successfully complete
these activities in a timely manner. All of the Company's sales are currently
denominated in U.S. dollars and, therefore, increases in the value of the U.S.
dollar relative to foreign currencies could make the Company's products less
competitive in foreign markets. In addition, revenue of the Company earned in
various countries where the Company does business may be subject to taxation
by more than one jurisdiction, thereby adversely affecting the Company's
earnings. There can be no assurance that such factors will not have an adverse
effect on the revenue from the Company's future international sales and,
consequently, the Company's financial condition or results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Sales and Marketing."
 
  Concentration of Share Ownership and Voting Power; Anti-Takeover
Provisions. Upon completion of this offering (assuming no exercise of the
Underwriters' over-allotment option), officers, directors and affiliates of
the Company will beneficially own approximately 54.1% of the Company's
outstanding Common Stock. As a result, these stockholders as a group will be
able to control the management and affairs of the Company and all matters
requiring stockholder approval, including election of directors, any merger,
consolidation or sale of all or substantially all of the Company's assets and
any other significant corporate transactions. The concentration of ownership
could have the effect of delaying or preventing a change in control of the
Company, reducing the likelihood of any acquisition of the Company at a
premium price. See "Principal and Selling Stockholders."
   
  Upon the closing of this offering, the Company's Board of Directors ("Board
of Directors" or "Board") has the authority to issue up to 2,000,000 shares of
Preferred Stock and to determine the price, rights, preferences and privileges
of those shares without any further vote or action by the stockholders. The
rights of the holders of Common Stock will be subject to, and may be adversely
affected by, the rights of the holders of any Preferred Stock that may be
issued in the future. The issuance of shares of Preferred Stock, while
potentially providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of making it
more difficult for a third party to acquire a majority of the outstanding
voting stock of the Company. The Company has no present intention to issue
shares of Preferred Stock. In addition, certain provisions of the Company's
Restated Certificate of Incorporation may have the effect of delaying or
preventing a change of control of the Company, which could adversely affect
the market price of the Company's Common Stock. These provisions provide,
among other things, that the Board of Directors is divided into three classes
to serve for staggered three-year terms, that a director may be removed from
the Board of Directors only for cause and only upon the vote of at least 66
2/3% of the voting power of all outstanding shares of the Company's capital
stock, that stockholders may not take action by written consent, that the
ability of stockholders to call special meetings of stockholders and to raise
matters at meetings of stockholders is restricted and that certain amendments
of the Company's Restated Certificate of Incorporation, and all amendments by
the stockholders of the Company's Amended and Restated Bylaws, require the
approval of holders of at least 66 2/3% of the voting power of all outstanding
shares. In addition, the Company is subject to the anti-takeover provisions of
Section 203 of the Delaware General Corporation Law, which will prohibit the
Company from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless the business
combination is approved in a prescribed manner. The application of Section 203
also could have the effect of delaying or preventing a change of control of
the Company. See "Description of Capital Stock."

  Broad Management Discretion over Use of Proceeds. The primary purposes of
this offering are to increase the Company's equity capital, to create a public
market for the Company's Common Stock and to facilitate future access by the
Company to public capital markets. A significant portion of the anticipated
net proceeds to the Company from this offering have not been designated for
specific uses. Accordingly, management of the Company will have broad
discretion with respect to the use of these funds. See "Use of Proceeds."
 
  No Prior Market; Possible Volatility. Prior to this offering there has been
no public market for the Common Stock of the Company. The initial public
offering price will be determined by negotiations among the Company, the
Selling Stockholders and the Representatives of the Underwriters. See
"Underwriting" for a discussion of the factors to be considered in determining
the initial public offering price. There can be no assurance that an active
public market will develop or be sustained after this offering or that the
market price of the Common Stock will not decline below the initial public
offering price. Future announcements concerning the Company or its
competitors, quarterly variations in operating results, announcements of
technological innovations, the introduction of new products or changes in
product pricing policies by the Company or its competitors, proprietary rights
or other litigation, changes in earnings estimates by market analysts or other
factors could cause the market price of the Common Stock to fluctuate
substantially. In addition, stock prices for many technology companies
fluctuate widely for reasons which may be unrelated to operating results.
These fluctuations, as well as general economic, market and political
conditions such as recessions or military conflicts, may materially and
adversely affect the market price of the Company's Common Stock. See "--
Potential Fluctuations in Operating Results."
 
  Shares Eligible for Future Sale; Registration Rights. Sale of substantial
amounts of Common Stock in the public market following this offering could
have an adverse effect on the price of the Common Stock. Immediately upon the
effectiveness of this offering, 2,100,000 shares will be freely tradeable.
Commencing 180 days following the date of this offering, 8,048,789 additional
shares will become freely tradeable upon the expiration of agreements not to
sell such shares, subject to compliance with Rule 144. Hambrecht & Quist LLC
may, in its sole discretion and at any time without notice, release all or any
portion of the securities subject to such agreements. The remaining 2,021,182
shares held by existing stockholders become eligible for sale at various times
over a period of less than two years, subject to the limitations of Rule 144.
Immediately after this offering, the Company intends to register approximately
3,150,000 shares of the Company's Common Stock reserved for issuance under its
stock option and purchase plans. See "Shares Eligible for Future Sale."
 
  As of the effective date of the Registration Statement, the holders of
6,789,050 shares of the Company's Common Stock will be entitled to certain
piggyback registration rights with respect to such shares. If the Company were
required to include in a Company initiated registration shares held by such
holders pursuant to the exercise of their piggyback registration rights, such
sale might have an adverse effect on the Company's ability to raise needed
capital. See "Description of Capital Stock."
 
  Immediate and Substantial Dilution to New Investors. The initial public
offering price is substantially higher than the book value per outstanding
share of Common Stock. Investors purchasing Common Stock in this offering
will, therefore, incur immediate dilution of $8.34 in net tangible book value
per share of Common Stock from the initial public offering price and may incur
additional dilution upon the exercise of outstanding stock options. See
"Dilution."

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 1,700,000 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$15,060,000 (approximately $17,431,500 if the Underwriters' over-allotment
option is exercised in full), assuming the shares offered hereby are sold at a
public offering price of $10.00 per share. The principal purposes of the
offering are to obtain additional working capital, establish a public market
for the Company's Common Stock and facilitate future access to public markets.
The Company will not receive any proceeds from the sale of Common Stock by the
Selling Stockholders.
   
  The Company expects the net proceeds to be used for general corporate
purposes, including working capital and possible repayment of borrowings under
the Company's revolving and bridge credit facilities. As of June 30, 1996 the
Company had outstanding borrowings of $524,000 under its $3.0 million
revolving credit facility and no borrowings outstanding under its $2.0 million
bridge credit facility. The Company's revolving line of credit and its bridge
credit facilities bear interest at the bank's prime lending rate plus 1.0%.
The Company's revolving credit facility expires on July 15, 1997, while
amounts borrowed under the bridge facility would be due on the earlier of 120
days following the loan advance or November 28, 1996. The Company has borrowed
under its credit facilities to provide working capital. A portion of the net
proceeds may also be used to acquire or invest in complementary businesses or
products or to obtain the right to use complementary technologies. While from
time to time the Company evaluates potential acquisitions of such businesses,
products or technologies, and anticipates continuing to make such evaluations,
there are no present understandings, commitments or agreements with respect to
any acquisition of other businesses, products or technologies. Pending such
uses, the proceeds will be invested in interest-bearing securities.     
 
                                DIVIDEND POLICY
   
  The Company has never paid or declared any cash dividends. It is the present
policy of the Company to retain earnings to finance the growth and development
of the business and, therefore, the Company does not anticipate paying cash
dividends on its Common Stock in the foreseeable future. In addition, the
Company's bank credit facilities contain covenants that prohibit the Company
from paying dividends without prior bank consent.

                                   DILUTION
 
  The net tangible book value of the Company as of June 30, 1996 was $5.1
million or $.49 per share of Common Stock. Net tangible book value per share
represents the amount of total tangible assets of the Company reduced by the
amount of its total liabilities and divided by the total number of shares of
Common Stock outstanding (reflecting the conversion of all outstanding
Preferred Stock and convertible notes into shares of Common Stock upon the
closing of the offering made hereby). Without taking into account any other
change in such net tangible book value after June 30, 1996, other than to give
effect to the sale by the Company of 1,700,000 shares offered hereby at an
assumed initial public offering price of $10.00 per share and receipt of the
estimated net proceeds therefrom, the pro forma net tangible book value of the
Company as of June 30, 1996 would have been approximately $20.2 million, or
$1.66 per share. This represents an immediate increase in such net tangible
book value of $1.17 per share to existing stockholders and an immediate
dilution of $8.34 per share to new investors. The following table illustrates
this per share dilution:

(1) Sales by Selling Stockholders in this offering will reduce the number of
    shares held by existing stockholders to 10,069,971 or approximately 82.7%
    of the total number of shares of Common Stock outstanding after this
    offering (10,009,971 or 80.6% if the Underwriters' over-allotment option
    is exercised in full), and will increase the number of shares held by new
    investors to 2,100,000 or approximately 17.3% of the total number of
    shares of Common Stock outstanding after the offering (2,415,000 or 19.4%

  The above computations assume no exercise of options after June 30, 1996. As
of June 30, 1996, there were outstanding options to purchase 1,449,285 shares

the extent outstanding options are exercised, there will be further dilution
to new investors. See Note 6 of Notes to Financial Statements of Visigenic.

  The following selected consolidated financial data at March 31, 1995 and
1996 and for the years ended March 31, 1994, 1995, and 1996 have been derived

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  This Prospectus contains forward-looking statements. Actual results could
differ materially from those projected in the forward-looking statements as a
result of the risks described below and elsewhere in this Prospectus.
 
OVERVIEW
 
  The Company commenced operations in February 1993 and was engaged
principally in product and market research and product development until the
launch of its initial products in November 1994. The Company shipped version
1.0 of the VisiODBC Software Development Kit ("SDK") and the VisiODBC Drivers
and DriverSets in November 1994, version 1.0 of its VisiChannel product in
March 1996 and version 2.0 of its VisiODBC product line in June 1996. The
Company first recognized material revenue in the fourth quarter of fiscal
1995.
 
  The Company's revenue is derived from license fees from licensing its
products, royalties from VARs, ISVs and distributors, and fees for services
related to its products, including software maintenance, development
contracts, consulting and training. License fees for the Company's products
vary according to the specific products licensed. Terms and conditions of
individual license transactions, including prices and discounts, are often
highly negotiated based on volumes and commitments and vary considerably from
customer to customer. Certain of the Company's license arrangements with VARs
and ISVs provide for sublicense fees payable to the Company based on a percent
of the VAR's or ISV's net revenue. Certain of the Company's license
arrangements with VARs and ISVs provide for fixed fees for the right to make
and distribute an unlimited number of copies of the Company's product for a
specified period of time. Service revenue is primarily attributable to lower
margin maintenance and other revenue, including training revenue and
engineering development fees. Most of the Company's license revenue to date is
attributable to non-recurring license fees for its database connectivity
products, particularly its VisiODBC product line, and fees from related
services. The Company currently expects that license revenue from its database
connectivity products will account for a substantial majority of its revenue
for the remainder of fiscal 1997 and for the foreseeable future. Factors
adversely affecting the pricing of or demand for its products could have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
  The Company generally recognizes revenue from license and pre-paid royalty
fees upon delivery of software products if there are no significant post-
delivery obligations, if collection is probable and if the license agreement
requires payment within 90 days. If significant post-delivery obligations
exist or if a product is subject to customer acceptance, revenue is deferred
until no significant obligations remain or acceptance has occurred. Royalty
revenue (other than from pre-paid royalties) is recognized when it is reported
by VARs, ISVs and distributors. Maintenance revenue from ongoing customer
support and product upgrades is recognized ratably over the term of the
applicable maintenance period, which is typically 12 months. Consulting and
training revenue is generally recognized as services are performed over the
term of the agreement. If maintenance revenue is included in a license
agreement, such amount is unbundled from the license fee at its fair market
value. Revenue from engineering development work is generally recognized on a
percentage of completion basis. If a transaction includes both license and
service elements, license fee revenue is recognized upon shipment of the
software, provided services do not include significant customization or
modification of the base product and payment terms are not subject to
acceptance criteria. In cases where license fee payments are contingent upon
the acceptance of services, revenues from both the license and service
elements are deferred until the acceptance criteria are met. See Note 2 of
Notes to Consolidated Financial Statements of Visigenic.
 
  The Company licenses its products to VARs and ISVs, who include the
Company's products in their own products, and to end users, who deploy the
Company's products in their own computing environments. A substantial portion
of the Company's license revenue to date is attributable to licenses to VARs
and ISVs. A relatively small number of VAR and ISV customers have accounted
for a significant percentage of the
 
                                      20
<PAGE>
 
Company's license revenue. For fiscal 1996, licenses to the Company's ten
largest customers accounted for approximately 78% of the Company's total
revenue and licenses to one customer, Platinum technology, Inc., accounted for
approximately 25% of the Company's total revenue. For the first quarter of
fiscal 1997, licenses to the Company's ten largest customers accounted for
approximately 75% of the Company's total revenue and licenses to one customer,
Cisco, accounted for approximately 34% of the Company's total revenue. The
Company expects that licenses to a limited number of VAR and ISV customers
will continue to account for a large percentage of revenue for the foreseeable
future.
 
  The sales cycles associated with the license of the Company's products is
often lengthy (typically ranging from six to twelve months) and is subject to
a number of significant delays over which the Company has little or no
control. In some cases, the license of the Company's software products is an
enterprise-wide decision by prospective end user customers or a product
strategy decision by VARs and ISVs. Generally, the Company must provide a
significant amount of information to prospective customers regarding the use
and benefits of the Company's products as part of its sales efforts. In
addition, the implementation of some of the Company's products involves a
significant commitment of resources by prospective customers and may require
substantial reengineering of customers' computing environments. The cost to
the customer of the Company's product is typically only a portion of the
related hardware, software, development, training and integration costs of
implementing a large scale system. Given these factors and the expected
continued dependence on a limited number of customers for a substantial part
of license revenue, the loss of a major customer or any reduction or delay in
sales to or implementations by such customers could have a material adverse
effect on the Company's business, results of operations, and financial
condition.
 
  The Company markets its products in North America through its direct sales
and telesales organizations and through VARs and ISVs. Throughout the rest of
the world, the Company markets its products through distributors, VARs and
ISVs. International revenue accounted for approximately 10% of total revenue
in fiscal 1996 and approximately 4% of total revenue for the first quarter of
fiscal 1997. In February 1996, the Company opened a European sales office in
France. The Company intends to increase its international sales force and
focus on establishing additional international distributor, VAR and ISV
relationships. The Company expects that international revenue will account for
an increasing portion of total revenue in the future. As a result, failure to
manage international sales appropriately could have a material adverse effect
on the Company's business, results of operations and financial condition. See
"Risk Factors--International Sales."
 
  With the exception of the third quarter of fiscal 1996, the Company's
revenue has increased in each of the last six quarters. The Company's limited
operating history, however, makes the prediction of future operating results
difficult. The Company expects that prior growth rates of the Company's
software products revenue will not be sustainable in the future. The Company's
future operating results will depend on many factors, including the size,
timing and terms and conditions of individual license transactions; the
relatively long sales and implementation cycles for the Company's products;
the delay or deferral of customer implementations; changes in the Company's
operating expenses; the ability of the Company to develop and market new
products and control costs; market acceptance of new products; timing of
introduction or enhancement of products by the Company or its competitors; the
level of product and price competition; the ability of the Company to expand
its direct sales and telesales force, its indirect distribution channels and
its customer support capabilities; activities of and acquisitions by
competitors; changes in connectivity software, database technology and
industry standards; changes in the mix of products and services sold; changes
in the mix of channels through which products and services are sold; levels of
international sales; personnel changes and difficulties in attracting and
retaining qualified sales, marketing and technical personnel; changes in
customers' budgeting cycles; foreign currency exchange rates; quality control
of products sold; and general economic conditions. The Company has not been
profitable to date and the Company currently anticipates that it will operate
at a loss through at least the middle of 1997. There can be no assurance that
any of the Company's business or strategies will be successful or that the
Company will be able to achieve or sustain profitability on a quarterly or
annual basis.
 
  The Company's sales generally reflect a relatively high amount of revenue
per order. The loss or delay of individual orders, therefore, can have a
significant impact on the revenue and quarterly results of the Company.
 
                                      21
<PAGE>
 
Because the Company's operating 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 significant losses. To the extent such expenses precede, or
are not subsequently followed by, increased revenue, the Company's operating
results would be materially adversely affected. As a result of these and other
factors, revenue for any quarter is 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. It is likely that in some future quarter
the Company's operating results will be below the expectations of market
analysts and investors. In such event, the price of the Company's Common Stock
would likely be materially adversely affected.
 
  The Company acquired PostModern effective May 31, 1996. The transaction was
accounted for as a purchase. Except for certain combined condensed financial
statements included elsewhere in this Prospectus and for the presentation of
certain pro forma revenue amounts herein, PostModern's financial results prior
to the effective date of the acquisition are not included in the Company's
financial results presented herein. The operating results of the PostModern
business are included in the Company's results of operations for the last
month of the first quarter of fiscal 1997. The Company's ability to
successfully integrate PostModern will depend upon several factors, including
but not limited to, successful integration of the products and operations of
PostModern into the Company. See "Risk Factors -- Limited Operating History;
History of Losses; Recent Acquisition of Distributed Object Connectivity
Business."

RESULTS OF OPERATIONS
 
  The Company first recognized material revenue in the fourth quarter of
fiscal 1995 after the Company shipped version 1.0 of its VisiODBC product
line. As a result, the Company believes that period-to-period comparisons of
annual operating results are less meaningful than an analysis of recent
quarterly results.
 
  The following tables set forth statements of operations for each of the six
quarters ended June 30, 1996, including such amounts expressed as a percentage
of total revenue. This quarterly information is unaudited, but has been
prepared on the same basis as the annual consolidated financial statements
and, in the opinion of the Company's management, reflects all adjustments
(consisting only of normal recurring adjustments) necessary for a fair
representation of the information for the periods presented. Such statements
of operations should be read in conjunction with the Company's audited
consolidated financial statements and notes thereto included elsewhere herein.
Operating results for any quarter are not necessarily indicative of results
for any future period.

REVENUE
 
  Software Products. Software products revenue increased by 402% from $892,000
in fiscal 1995 to $4.5 million in fiscal 1996 and increased by 360% from
$544,000 in the first quarter of fiscal 1996 to $2.5 million in the first
quarter of fiscal 1997. The Company had no software products revenue in fiscal
1994. The revenue increases from fiscal 1995 to fiscal 1996 and from the first
quarter of fiscal 1996 to the first quarter of fiscal 1997 were primarily due
to an increased volume of licensing of the Company's database connectivity
products, resulting from an increase in the number of products offered and the
expansion of the Company's direct sales and telesales organizations. The
decline in software products revenue in the third quarter of fiscal 1996
resulted primarily from the delay in completion of a large sale which closed
in the fourth quarter.
 
  Service and Other. Service and other revenue, including maintenance revenue,
development fees and consulting and training revenue, increased by 391% from
$223,000 in fiscal 1995 to $1.1 million in fiscal 1996 and increased by 24%
from $367,000 in the first quarter of fiscal 1996 to $456,000 in the first
quarter of fiscal 1997. The Company had no service and other revenue in fiscal
1994. The revenue increases from fiscal 1995 to fiscal 1996 and from the first
quarter of fiscal 1996 to the first quarter of fiscal 1997 were due to the
greater licensing of products to customers under agreements with a maintenance
component and growth in training, consulting and development activities.
 
COST OF REVENUE
 
  Software Products. Cost of software products revenue includes product
packaging, documentation, production and shipping. Cost of software products
revenue increased from $36,000 in fiscal 1995 to $284,000 in fiscal 1996 and
increased from $43,000 in the first quarter of fiscal 1996 to $138,000 in the
first quarter of fiscal 1997. The increases resulted from increased volume of
licensing of the Company's products. The Company had no costs of software
products revenue in fiscal 1994.
 
  Service and Other. Cost of service and other revenue consists primarily of
personnel and personnel related overhead allocation, facility and systems
costs incurred in providing consulting, training, customer support and
engineering development services. Cost of service and other revenue increased
from $259,000 in fiscal 1995 to $727,000 in fiscal 1996 and increased from
$146,000 in the first quarter of fiscal 1996 to $295,000 in the first quarter
of fiscal 1997. This increase reflects the effect of fixed costs resulting
from the Company's investment during fiscal 1996 and the first quarter of
fiscal 1997 in a larger customer support organization in anticipation of
entering into an increasing number of licenses with maintenance components.
The Company had no costs of service and other revenue in fiscal 1994. The
Company intends to continue investing resources in its customer support
organization. The Company currently expects that costs of service and other
revenue will increase in absolute dollar amount from the level for fiscal
1996.
 
OPERATING EXPENSES
   
  Product Development. Product development expenses include expenses
associated with the development of new products, enhancements of existing
products and quality assurance activities, and consist primarily of employee
salaries, personnel-related overhead allocation, benefits, consulting costs,
the cost of technology licensed from other software companies and the cost of
software development tools. Product development expenses increased by 38% from
$3.2 million in fiscal 1995 to $4.3 million in fiscal 1996 and by 127% from
$1.4 million in fiscal 1994 to $3.2 million in fiscal 1995. Product
development expenses increased by 127% from $729,000 in the first quarter of
fiscal 1996 to $1.7 million in the first quarter of fiscal 1997. The increases
in the dollar amount of product development expenses were primarily
attributable to costs of additional personnel and full-time contractors in the
Company's product development operations and, to a lesser extent, the
licensing of existing technology from third parties which has been or will be
incorporated into the Company's products. The increase of product development
expenses in the third quarter of fiscal 1996 was the result of increased
consulting fees and licensing of third party technology which was expensed
because it was used exclusively in the development process. Of the product
development costs, approximately $1.3 million in fiscal 1994 and $1.2 million
in fiscal 1995 consisted of expenses for the development of a product the
Company later chose not to     
 
                                      24
<PAGE>
 
introduce commercially. There can be no assurance that the Company will not
devote significant resources in the future to develop and market other
products that the Company may choose not to introduce commercially. The
Company anticipates that it will continue to devote substantial resources to
product development, including acquiring or licensing technology from others,
in order to introduce new products, enhance existing products or accelerate
its time to market. The Company plans to hire a substantial number of product
development personnel in fiscal 1997. The Company currently expects that
product development expenses will increase in absolute dollar amount from the
level for fiscal 1996.
 
  In accordance with Statement of Financial Accounting Standards No. 86, the
Company has charged all software development costs to product development
expense as incurred because expenditures which were eligible for
capitalization in prior periods were insignificant.
   
  Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, commissions and bonuses earned by sales and marketing personnel,
personnel related overhead allocation, field office rent and related expenses,
travel and entertainment, and advertising and promotional expenses. Sales and
marketing expenses increased by 113% from $1.5 million in fiscal 1995 to $3.2
million in fiscal 1996 and by 200% from $503,000 in fiscal 1994 to $1.5
million in fiscal 1995. Sales and marketing expenses increased by 215% from
$636,000 in the first quarter of fiscal 1996 to $2.0 million in the first
quarter of fiscal 1997. The increases in sales and marketing expenditures
reflect primarily the hiring of additional sales and marketing personnel,
costs associated with expanded advertising and promotional activities,
increased sales commissions and increased costs associated with field sales
offices. Of sales and marketing costs, approximately $500,000 in fiscal 1994
and $900,000 in fiscal 1995 consisted of expenses relating to a product the
Company later chose not to introduce commercially, none of which expenses is
of a recurring nature. The Company plans to hire a substantial number of sales
and sales support personnel in fiscal 1997. The Company expects that sales and
marketing expenses will continue to increase in absolute dollar amount as the
Company continues to expand its sales and marketing efforts domestically and
internationally, establishes additional sales offices and increases
advertising and promotional activities. The Company currently expects that
sales and marketing expenses will increase in absolute dollar amount from the
level for fiscal 1996.     
 
  General and Administrative. General and administrative expenses consist
primarily of salaries and occupancy costs for administrative, executive and
finance personnel and personnel related overhead allocation. These expenses
increased by 68% from $872,000 in fiscal 1995 to $1.5 million in fiscal 1996
and by 45% from $600,000 in fiscal 1994 to $872,000 in fiscal 1995. General
and administrative expenses increased by 41% from $335,000 in the first
quarter of fiscal 1996 to $473,000 in the first quarter of fiscal 1997. The
increases in the absolute dollar amounts of general and administrative
expenses were primarily due to increased staffing and associated expenses
necessary to manage and support the Company's increased scale of operations.
The Company believes that the absolute dollar amount of its general and
administrative expenses will continue to increase as a result of the
anticipated expansion of the Company's administrative staff to support growing
operations and expenses associated with being a public company.
 
INTEREST AND OTHER INCOME, NET
 
  Interest and other income, net, is comprised primarily of interest income
earned on the Company's cash and cash equivalents. Interest and other income,
net, decreased by 10% from $94,000 in fiscal 1995 to $85,000 in fiscal 1996
and increased by 124% from $42,000 in fiscal 1994 to $94,000 in fiscal 1995.
Interest and other income, net, increased from $1,000 in the first quarter of
fiscal 1996 to $6,000 in the first quarter of fiscal 1997. The variations
reflect changing cash balances.
 
PROVISION FOR INCOME TAXES
 
  As of March 31, 1996, the Company had federal and state net operating loss
carryforwards of approximately $9.8 million and $2.0 million, respectively,
which expire at various dates through 2011. In addition, as of March 31, 1996,
the Company had general business credit carryforwards of approximately
$372,000, which expire at various dates through 2011. Utilization of the net
operating loss carryforwards and business credits may
 
                                      25
<PAGE>
 
be subject to a substantial annual limitation due to the ownership change
limitations provided by the Internal Revenue Code of 1986, as amended, and
similar state provisions. See Note 8 of Notes to Consolidated Financial
Statements of Visigenic.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since inception, the Company has financed its operations and met its capital
expenditure requirements primarily from proceeds from the private sales of
Preferred and Common Stock. Through June 30, 1996, the Company had raised
$17.8 million from the sale of Preferred and Common Stock. At June 30, 1996,
the Company's principal sources of liquidity included cash and cash
equivalents of $1.9 million and a $1.0 million revolving line of credit
agreement which expires on August 15, 1996. Advances under the agreement,
which bear interest at the bank's prime lending rate plus 1.25%, are limited
to 80% of eligible accounts receivable and are secured by substantially all of
the assets and contractual rights of the Company. After the end of fiscal
1996, the Company borrowed $524,000 under the line of credit, which bore
interest at a rate of 9.5%, as of June 30, 1996. The line of credit agreement
also contains certain financial restrictions and covenants. The Company is in
compliance with these financial restrictions and covenants. See Note 3 of
Notes to Consolidated Financial Statements of Visigenic.
 
  On July 16, 1996 the Company executed an amended loan and security agreement
which increased the revolving line of credit to $3.0 million and extended its
term to July 15, 1997. The amended agreement also provides for a $2.0 million
bridge loan for a term ending the earlier of 120 days following the loan
advance or November 28, 1996. As consideration for the bridge loan the Company
will issue a five year warrant to purchase up to 6,666 shares of the Company's
Common Stock. Borrowings outstanding under the amended agreement will bear
interest at the bank's prime lending rate plus 1.0%.
   
  On May 24, 1996, the Company sold 444,444 shares of its Series C Preferred
Stock at a price of $9.00 per share to three investors, for aggregate proceeds
of $4.0 million. The Company has the right to require these investors to
purchase up to an additional $4.0 million in convertible notes at any time
prior to October 31, 1996. If the Company has not completed an initial public
offering of its Common Stock by August 30, 1996, in order to require the
purchase of these convertible notes after September 30, 1996, the Company must
achieve revenue of at least $3.6 million for the quarter ended September 30,
1996. Between May 28 and June 7, 1996, the Company issued $2.0 million
principal amount of these convertible notes, bearing interest at the rate of
8.25% per annum. The principal amount of the notes and all accrued interest
are due three years after the issuance date. However, upon the closing of the
Company's initial public offering, the principal amount of each note and all
accrued interest will automatically convert into shares of the Company's
Common Stock at the lesser of $13.00 per share or the offering price per share
to the public. Upon the closing of the Company's initial public offering, the
Series C Preferred Stock will automatically convert into shares of the
Company's Common Stock. The Company used a portion of the proceeds from the
sale of the Series C Preferred Stock and the convertible notes to pay amounts
payable in connection with the closing of the acquisition of PostModern. See
"--PostModern Acquisition" and Note 9 of Notes to Consolidated Financial
Statements of Visigenic.     
 
  The Company's operating activities used cash of $2.2 million in fiscal 1994,
$4.6 million in fiscal 1995, $2.6 million in fiscal 1996 and $4.6 million in
the first quarter of fiscal 1997. The increased use of cash in fiscal 1995 as
compared with fiscal 1994 was primarily attributable to increased operating
costs and increased accounts receivable reduced by an increase in accounts
payable, accrued liabilities and deferred revenue. The decline in net cash
used in operations in fiscal 1996 as compared with fiscal 1995 was primarily
due to an increase in accounts payable, accrued liabilities and deferred
revenue. The increased use of cash in the first quarter of fiscal 1997 was
primarily due to an increase in accounts receivable.
 
  The Company used $477,000, $378,000, $1.1 million and $2.6 million of net
cash during fiscal 1994, fiscal 1995, fiscal 1996 and the first quarter of
fiscal 1997, respectively, for investing activities, due primarily to
purchases of property and equipment. Financing activities provided $5.6
million, $2.6 million, $5.5 million and $6.7 million of net cash during fiscal
1994, fiscal 1995, fiscal 1996 and the first quarter of fiscal 1997,
respectively, due to the issuance of Preferred and Common Stock and
convertible notes and debt financing.
 
                                      26
<PAGE>
 
   
  Deferred revenue consists primarily of the unrecognized portion of revenue
under maintenance and support contracts (which revenue is deferred and
recognized ratably over the term of such contracts) and advance payment of
software development fees and software license fees. The Company expects
deferred revenue of $560,000 from maintenance and support contracts and
$400,000 from software development and software license fees to be realized in
the next twelve months. Capital expenditures were primarily for computers,
furniture and equipment. The Company expects that its capital expenditures
will increase as the Company's employee base grows, and has budgeted $1.4
million for such capital expenditures for fiscal 1997. As of June 30, 1996,
the Company did not have any material commitments for capital expenditures.
    
  The Company believes that the proceeds from the sale of the Common Stock
offered hereby, together with its existing sources of liquidity and cash
generated from operations, will satisfy the Company's projected working
capital and other cash requirements for at least the next twelve months.
Although operating activities may provide cash in certain periods, to the
extent the Company experiences growth in the future, the Company anticipates
that its operating and investing activities will use cash. Any such future
growth and any acquisitions of other technologies, products or companies may
require the Company to obtain additional equity or debt financing, which may
not be available or may be dilutive.
 
POSTMODERN ACQUISITION
   
  In May 1996, the Company completed the acquisition of PostModern, a supplier
of distributed object connectivity software. In the acquisition, which was
structured as a merger, the Company issued 3,099,821 shares of its Common
Stock and paid a total of $2.3 million in exchange for all of PostModern's
outstanding shares. The Company also assumed PostModern's outstanding stock
options and reserved 361,785 shares of the Company's Common Stock for issuance
upon exercise of such options. The Company also incurred acquisition-related
costs of approximately $450,000, resulting in a total purchase price of
approximately $13.1 million. In addition, the Company made cash payments,
subject to one-year vesting and totaling $1.5 million, to certain PostModern
employees. The acquisition of PostModern was accounted for as a purchase in
the quarter ended June 30, 1996. The Company recorded a write-off in the
quarter ended June 30, 1996 of approximately $12.0 million of in process
product development that had not reached technological feasibility and, in
management's opinion, had no probable alternative future use. The remaining
purchase price of approximately $1.1 million will be amortized over two years.
       
  The following pro forma revenue information gives effect to the May 1996
acquisition of PostModern as if it had occurred on April 1, 1995. This
information is unaudited and is based on the respective historical financial
statements of the Company and PostModern. The Company's acquisition of
PostModern was accounted for as a purchase under accounting rules which
require presentation of combined operating results subsequent to the
acquisition date. The following pro forma data are presented for comparison
purposes only. This data should be read in conjunction with the pro forma
condensed combined financial statements and historical financial statements
contained herein.     
 
  This revenue data has been prepared on the same basis as the annual
consolidated financial statements and, in the opinion of the Company's
management, reflects all adjustments necessary for a fair presentation of the
information for the periods presented.

INDUSTRY BACKGROUND
 
  In an increasingly complex computing environment, today's enterprises
require flexible access to data and applications, regardless of whether the
data and applications are located at the central office, a remote office or
across the Internet. This requirement is being driven by the following market
trends:
 
  . The increasing use of multiple database management systems ("DBMSs"),
    requiring DBMS-independent client/server database connectivity solutions.
 
  . The increasing use of object-oriented technologies to provide distributed
    application solutions.
 
  . The increasing use of Internet and Intranet technologies within
    mainstream commercial markets, which is increasing the demand for
    applications capable of operating in distributed computing environments.
 
  Database Connectivity
 
  Client/server computing has given organizations the flexibility to develop
and deploy applications on a wide variety of computer platforms and DBMSs. The
computing infrastructure of the typical enterprise now consists of a
heterogeneous mix of operating systems, databases, networks and hardware. One
industry survey of Fortune 500 companies found that these companies use an
average of six different DBMSs. For example, an enterprise may support the
Windows 3.1, Windows NT, UNIX and MVS operating system platforms running
Microsoft SQL Server, Oracle and IBM DB2 DBMSs. To manage this heterogeneous,
cross-platform database environment, a common method of accessing, managing
and analyzing data from multiple databases was needed. The Open Database
Connectivity ("ODBC") standard was created to address this problem.
 
  ODBC, originally developed by Microsoft, is an industry standard that is
based on a specification defined by the SQL Access Group, a consortium of
database, software and hardware vendors. ODBC provides a common data access
application programming interface ("API") for developers building DBMS-
independent applications. With ODBC, a single application can access multiple
databases on multiple platforms, avoiding the need for developers to write
versions of each application for each DBMS vendor's proprietary data access
API. The ODBC API is supported by most major software vendors in their
programming languages, application development tools and report writing tools,
including Microsoft Visual Basic and Visual C++, Sybase PowerBuilder and the
Oracle 2000 family, and Seagate Crystal Reports.
 
  Although ODBC provides heterogeneous database connectivity, organizations
seeking the benefits afforded by ODBC have encountered two limitations as they
move to a more distributed computing environment. First, ODBC development
tools and ODBC drivers originally were only available for Windows platforms.
This limited the ability of enterprises to realize the multi-platform
potential of ODBC and to deploy ODBC solutions in multi-platform computing
environments such as Intranets and the Internet. Second, initial
implementations of ODBC are client-centric and are suitable for departmental
or limited enterprise deployments. These client-centric implementations
require that an ODBC driver and database-specific network libraries for each
DBMS to be accessed reside on each client system. For larger deployments,
which may involve hundreds, or even thousands,
 
                                      28

of ODBC-enabled client systems accessing multiple DBMSs, maintaining and
managing this client/server infrastructure is expensive and difficult because
each client system must be updated for each new version of the DBMS and the
ODBC driver. The Company believes that organizations need a simplified,
server-centric ODBC database access architecture for larger deployments,
including Intranet and Internet computing environments.
 
  Distributed Object Connectivity
 
  In today's rapidly evolving computing environments, enterprises require
improved data access as well as improved software application architectures.
Computing environments are becoming more distributed, with numerous client and
server machines networked together within a single enterprise as well as
across the Internet. The traditional method of building applications as
monolithic programs is not suited for this distributed environment. Instead,
applications must be more modular in nature, where the application is built as
a set of modules that can be distributed over a number of client and server
systems. Enterprises can improve computing performance by distributing
application logic over these computing networks so that the appropriate
application logic resides on the most appropriate system. For example, logic
for the graphical user interface could reside on a client machine while the
business logic is located on one or more servers where the business
application resides and the logic that manipulates the data in the DBMS is
located on one or more servers where the data resides.
 
  Object-oriented programming languages like C++ and Java have enabled
software developers to develop and deploy distributed applications more
easily. These languages are based on the concept of objects, which are
reusable software components that contain both data and the related procedures
that act upon them. Objects are modular in nature and can be arranged or
reused in many different combinations to form new applications. This modular,
self-contained characteristic makes objects ideal for distributed computing
environments because applications can now be created by linking a series of
objects that may be distributed over a number of different systems.
 
  Significant challenges in distributed application development and deployment
include communications and interoperability between objects that are
distributed over a network. The Common Object Request Broker Architecture
("CORBA") specification, developed by the Object Management Group, a
consortium of software and hardware vendors and corporate end users, was
created to address these challenges. The CORBA specification defines an Object
Request Broker ("ORB") that manages and monitors the interactions of
distributed objects on a network. To enable interoperability among
applications using ORBs, CORBA also specifies the Internet Inter-ORB Protocol
("IIOP"), which defines a standard distributed messaging protocol for
communication between objects. CORBA-compliant objects are portable across
programming languages, development environments, computer platforms and
networks, which is an increasingly important attribute of applications in the
heterogeneous computing environments of the Internet, Intranets and
enterprises.
 
  Before the CORBA specification, many enterprises had not undertaken the
development and deployment of distributed applications because of the lack of
software development tools that provide a distributed object communication
infrastructure. This meant that building enterprise-wide distributed
applications entailed writing a new, proprietary communication
infrastructure--a task that was difficult and time-consuming for many
enterprises. The introduction of CORBA-compliant ORBs has freed enterprises
from having to write their own communication infrastructure and allows
enterprises to focus their development efforts on business logic. The Company
believes that enterprises now need commercially available ORBs from third
party vendors that provide this communications infrastructure.
 
  The Internet and Intranets Increase the Need for Distributed Applications
 
  The Internet has quickly emerged as an important aspect of business
computing. Internet-based business applications have expanded beyond
electronic mail to a broad range of business applications and services,
including electronic publishing, direct-to-customer transactions, product
marketing, advertising and customer support. The widespread use of the
Internet by enterprises has also resulted in the emergence of Intranets,
internal information systems based upon the Internet infrastructure. Intranets
use Internet protocols and applications to share information and services both
within the enterprise and across the Internet. Intranets allow the enterprise
to
 
                                      29
<PAGE>
 
distribute data and applications across geographically dispersed facilities as
well as enable customers, suppliers and other business partners to easily
access enterprise data and applications.
 
  The Internet and Intranets are large heterogeneous distributed computing
environments, consisting of vast numbers of networked client and server
systems and distributed databases. The rapid growth of the Internet and
Intranets is accelerating the importance of distributed applications that can
access data wherever the data resides. The Company believes business
applications increasingly will be comprised of objects, Java applets and
databases that are distributed on networks and dynamically assembled into
highly customized solutions. As a result, development and deployment tools for
database access and distributed object connectivity solutions are increasingly
key components of the software infrastructure required for Internet, Intranet
and enterprise computing environments.

  Database Connectivity Products
 
  The Visigenic software tools for database connectivity are based on the ODBC
standard and enable data access independent of both the DBMS and platform. The
ODBC products include the VisiODBC Drivers and DriverSets (formerly Visigenic
ODBC Drivers and Driver Sets), VisiODBC Software Development Kits (formerly
Visigenic ODBC Software Development Kits) and VisiChannel (formerly Visigenic
OpenChannel).

             [DIGITIZED ARTWORK OF VISIODBC DRIVERS APPEARS HERE]
 
  VisiODBC Drivers and DriverSets. The VisiODBC Drivers and DriverSets
(formerly Visigenic ODBC Drivers and DriverSets) provide cross-platform access
to multiple SQL relational DBMSs--including CA-Ingres, IBM DB2, Informix,
Microsoft SQL Server, Oracle and Sybase SQL Server (DBLib and CTLib)--from any
ODBC-enabled application. The VisiODBC Driver and DriverSets are made up of two
ODBC components: the Driver Manager and a set of database drivers. The Driver
Manager loads the ODBC drivers that an ODBC-enabled application requests. The
VisiODBC drivers provide the communication link between the ODBC-enabled
application and a specific DBMS; the drivers process ODBC function calls from
the application, translate them to DBMS-specific calls and return the results
of those calls to the application. For example, to access an Oracle DBMS, an
ODBC-enabled application, such as Microsoft Excel, would send SQL calls through
the VisiODBC Oracle driver. Likewise, to access an Informix DBMS, Microsoft
Excel would send the same SQL calls through a VisiODBC Informix driver. The
Company sells VisiODBC drivers separately or as the VisiODBC DriverSet, which
consists of the full set of VisiODBC drivers available for each platform.
VisiODBC Drivers are available for Windows 3.1, Windows NT, Windows 95, ATT
GIS, HP-UX, IBM AIX, SGI Irix, SCO, Solaris, Sun OS, Macintosh and Power
Macintosh and OS/2. The Company initially released VisiODBC Drivers and
DriverSets in November 1994.
 
  VisiODBC SDKs. VisiODBC SDKs (formerly Visigenic ODBC SDKs) allow developers
to develop vendor-independent database applications and ODBC drivers. Using the
VisiODBC SDKs, developers write database-independent C and C++ applications
that communicate simultaneously with multiple databases from different vendors.
Each VisiODBC SDK comes with the Driver Manager, header files, programmer's
reference and graphical utilities.
 
  Visigenic has ported the Microsoft ODBC 2.X SDK to ATT GIS, HP-UX, IBM AIX,
SGI Irix, SCO, Solaris, Sun OS, Macintosh, Power Macintosh and OS/2. Visigenic
currently has the exclusive right to license and port the Microsoft ODBC SDK
versions 2.X and 3.0 for Windows to all non-Microsoft platforms. The Company
released its first VisiODBC SDK in November 1994.
 
  VisiChannel. VisiChannel (formerly Visigenic OpenChannel) provides an
architecture that simplifies database connectivity in large distributed
application environments such as the Internet, Intranets and enterprise
computing environments. The Company initially released VisiChannel in March
1996.

                [DIGITIZED ARTWORK OF VISICHANNEL APPEARS HERE]
 
  VisiChannel's server-centric architecture shifts the administrative burden
and processing load for ODBC-enabled applications by relocating ODBC drivers
and network libraries away from each user's individual machine to a central
server, allowing easier administration and control. A "thin" database-
independent client driver connects to any database through the VisiChannel
Server, where server-side ODBC drivers manage the actual database connections.
Since database connections are centralized, VisiChannel can reduce the time and
resources spent on deploying and managing database applications.
 
  VisiChannel consists of the VisiChannel Client, Server and Manager. The
VisiChannel Client replaces the ODBC drivers and database vendor's proprietary
libraries on the client. The VisiChannel Server can be used to access any ODBC
data source, either through a VisiODBC Driver or other third party ODBC
drivers. The VisiChannel Server has been designed to support large numbers of
concurrent users through the use of a multi-threaded architecture, which
provides for efficient resource utilization, enhanced throughput and shared
resource integrity. The VisiChannel Manager is a monitoring tool that allows IT
professionals to monitor all VisiChannel connections and adjust system
configuration parameters from a single location.
 
  VisiChannel can be deployed for use with existing ODBC applications without
any changes to the client application. VisiChannel is optimized for large-scale
ODBC traffic and runs over standard TCP/IP transports, enabling it to be used
for database connectivity across the Internet. The Company is developing a
version of VisiChannel that will support the JDBC API for Java applets and
applications.
 
  The VisiChannel Server is available for Windows NT, and VisiChannel Clients
are available for Windows 3.1, Windows NT and Windows 95. The Company expects
to begin shipping VisiChannel Servers and Clients for UNIX in the second half
of 1996.
 
  Distributed Object Connectivity Products
 
  Visigenic develops and markets two Object Request Broker ("ORB") products:
VisiBroker for C++ and VisiBroker for Java (formerly Orbeline and BlackWidow).
Visigenic's ORBs, which are based on the Common Object Request Broker
Architecture ("CORBA") specification, provide an object-oriented solution for
the development and deployment of distributed applications.

            [DIGITIZED ARTWORK OF VISIBROKER FOR JAVA APPEARS HERE]
 
  VisiBroker for C++. VisiBroker for C++ (formerly ORBeline) provides a
communication framework that enables the development, deployment and management
of complex, distributed C++ applications. VisiBroker for C++ consists of two
main components: a development component and a runtime component. The
development component includes a code generator that converts object interfaces
specified in CORBA's Interface Definition Language ("IDL") into C++. The
developer adds application logic and the runtime code to the generated code to
create a distributed application. The generated code is used by the objects'
application logic to interact with the VisiBroker runtime component which
manages the communication among the distributed objects.
 
  VisiBroker for C++ operates on SunOS, Solaris, Digital UNIX, HP-UX, IBM AIX,
Windows NT and Windows 95 platforms. VisiBroker for C++ was first released in
September 1994 and the Company is currently shipping version 2.0.
 
  VisiBroker for Java. VisiBroker for Java (formerly BlackWidow) is the
industry's first client and server Java ORB. VisiBroker for Java enables
distributed computing on the Internet and Intranets. Like VisiBroker for C++,
VisiBroker for Java consists of a development component and a runtime
component. The VisiBroker for Java development component converts IDL
interfaces into client-side and server-side Java code. The VisiBroker for Java
runtime is written entirely in Java and can run in any Java-enabled Web
browser, such as Netscape Navigator 2.0. The VisiBroker for Java environment
allows Internet, Intranet and enterprise deployment. On the Internet, a user
can load a client-side VisiBroker for Java applet into any Java-enabled
browser, execute the applet and establish IIOP connectivity with CORBA objects,
whether the objects are written in Java or in another language such as C++ or
Smalltalk.
 
  The VisiBroker for Java development environment is available on Windows NT,
Windows 95 and Solaris. Distributed applications developed with VisiBroker for
Java can be deployed on any platform supporting the Java environment.
VisiBroker was first released in April 1996.
 
                                       36
<PAGE>
 
  VisiBroker Architecture. VisiBroker for C++ and VisiBroker for Java share a
common architecture. Both products use IIOP as their internal communications
protocol and do not rely on conversion of a proprietary protocol into IIOP in
order to interoperate with other ORB implementations. IIOP is an emerging
standard for distributed object messaging and is designed for applications
distributed across the Internet and Intranets. Each of the Company's VisiBroker
products is multi-threaded, facilitating scalability and enhancing throughput.
Applications developed using the Company's VisiBroker products can support
multiple concurrent threads to service both incoming and outgoing object
requests simultaneously, permitting objects within an application to process a
request without affecting the responsiveness of other objects within the
application. The Company's VisiBroker products have an agent-based architecture
and include one or more agents that communicate and monitor the location of the
ORB objects on the network. This agent-based architecture is designed to adapt
itself to changes in the objects and the network, such as a heavy system load
or the failure of objects. The architecture minimizes the need for
configuration files, making it easier to deploy and administer applications,
and enables automatic fail-over capabilities, significantly reducing
interruptions in any service provided as part of or implemented using the ORB.

  In fiscal 1996, one customer, Platinum technology, accounted for
approximately 25% of revenue and in the first quarter of fiscal 1997, one
customer, Cisco, accounted for approximately 34% of revenue. No other customer
accounted for more than 10% of revenue in either period. A relatively small
number of VAR and ISV customers have accounted for a significant percentage of
the Company's revenue, and the Company expects that sales to VAR and ISV
customers will continue to represent a significant portion of the Company's
revenue in future periods. In fiscal 1996, approximately 78% of the Company's
revenue was derived from ten customers. In the first quarter of fiscal 1997,
approximately 75% of the Company's revenue was derived from ten customers.

  The Company's products can be used in many applications, including the
following examples:
 
  Oracle Corporation. Oracle Corporation, a leading supplier of information
management software, wanted to provide their customers with access to
competitors' DBMSs. Their customers are increasingly operating in
heterogeneous environments and require a solution that allows them to develop
applications that access multiple DBMSs. Oracle integrated VisiODBC technology
in their Transparent Gateway, allowing them to support a single, standard
DBMS-independent API versus supporting multiple proprietary APIs of their
competitors. For the first time, Oracle provided their customers with direct
gateway access, providing distributed database capabilities, from the Oracle7
database to Sybase, Informix, and CA-Ingres.
 
  Healtheon. Healtheon, an Internet-based on-line healthcare and benefit
information and service company, needed a distributed object connectivity
solution for its applications. Healtheon is using VisiBroker for C++ as an
integral part of its technology infrastructure for its applications.
 
  Platinum technology. Platinum technology, a provider of application
development, business intelligence, database administration, data warehousing,
and systems software solutions, was seeking a consistent database access
solution for their Platinum Open Enterprise Management System ("POEMS")
products. Platinum was supporting several proprietary database access methods.
Platinum integrated VisiODBC technology and VisiChannel into the POEMS
architecture, providing Platinum with a single database access architecture to
support and providing their customers with database connectivity across
multiple databases, operating systems and hardware platforms.
 
SALES AND MARKETING
 
  The Company's sales and marketing objective is to achieve broad market
penetration by targeting multiple channels of distribution, including direct
sales and telesales, ISVs, VARs, SIs, international distributors and on-line
Internet sales. The Company is actively seeking to increase its base of VARs,
ISVs, SIs and international distributors.
 
  Direct Sales/Telesales. The Company's direct sales and telesales forces
focus on medium to large-sized VARs, ISVs and corporate IT opportunities. To
date, the direct sales and telesales forces have been primarily targeting
strategic VARs and ISVs to leverage their sales and marketing expertise as
well as their position in the market. The Company has direct sales offices or
personnel in San Mateo, California; Atlanta, Georgia; Boston, Massachusetts;
Dallas, Texas; Reston, Virginia and Paris, France. The Company's telesales
organization, based in San Mateo, California, works jointly with the direct
sales force to receive customer orders as well as proactively identify,
contact and qualify customer leads.
 
  Independent Software Vendors. The Company has relationships with a number of
ISVs to leverage their sales and marketing channels through joint marketing
programs and product bundling agreements.
 
  Value Added Resellers and System Integrators. VARs and SIs customize,
configure and install the Company's software products and bundle these
products with their software solutions and services.
 
  International Distributors. The Company believes that it is important to
develop a strong international presence and intends to do business in markets
outside of North America principally through distributors. International sales
accounted for 10% and 4% of revenue in fiscal 1996 and the first quarter of
fiscal 1997, respectively. The Company is working with its distributors to
develop end user, ISV, VAR and SI relationships in their respective
territories. As of June 30, 1996, the Company had 12 international
distributors, mostly in Europe and Asia.
 
                                      38
<PAGE>
 
  Internet Sales. Certain of the Company's products can be evaluated and
purchased electronically over the Internet. The Company believes that the
Internet can be an effective way to market its products to potential
customers.
 
  The Company's marketing efforts are directed at building brand name
awareness while also highlighting the value of the Company's database
connectivity and distributed object connectivity products. The Company's
marketing efforts include market research, product planning, creating
collateral materials, managing press coverage and other public relations,
identifying potential customers, advertising, attending tradeshows, speaking
at industry conferences, direct mail campaigns and establishing and
maintaining close relationships with recognized industry analysts. The Company
also maintains a home page on the Internet that is a source of sales leads.
 
  As of June 30, 1996, the Company's sales organization included 29 employees
and its marketing organization included 8 employees. The Company intends to
hire a significant number of additional sales and marketing personnel in
fiscal 1997 and beyond. An increase in the sales and marketing staff will be
required to expand both the Company's direct and indirect sales activities and
achieve revenue growth. Competition for such personnel is intense, and there
can be no assurance that the Company can attract, assimilate or retain such
personnel. Because of the complexity of database connectivity and distributed
object connectivity software products, the Company has in the past and expects
to continue in the future to experience a time lag between the date sales
personnel are hired and the date such persons become fully productive. If the
Company is unable to hire and train such personnel on a timely basis in the
future, the Company's business, financial condition and results of operations
could be materially adversely affected. See "Risk Factors--Reliance on VARs
and ISVs" and "--International Sales."
 
CUSTOMER SERVICE AND SUPPORT
 
  The Company believes that a high level of customer service and support is
critical to the Company's success. The services provided by the Company
include technical support, maintenance, training and consulting. These
services are designed to increase customer satisfaction and provide feedback
to the Company as to customers' demands and requirements.
 
  Technical Support and Maintenance. The Company offers customer support
through telephone, electronic mail and fax. Visigenic provides new software
releases, maintenance releases and enhancements under annual support
agreements with customers. Maintenance and customer support license fees are
not included in software license fees but are purchased separately for an
annual fee.
 
  Training and Consulting. The Company offers its customers education and
training programs, as well as customized consulting services. Fees for
training and consulting services are generally charged on a per diem basis,
separately from the Company's software products.
 
PRODUCT DEVELOPMENT
 
  The Company believes its future success will depend in large part on its
ability to expand the Visigenic product family by enhancing existing products,
integrating database connectivity technology with distributed object
connectivity technology and developing new products to meet a broad range of
customer needs. The Company's product development organization is responsible
for new product and technology development, product testing and user interface
development. This organization is working to expand the availability of the
Company's products on the leading hardware platforms, operating systems,
DBMSs, programming languages and networking and communication protocols.
 
  Since inception, the Company has made substantial investments in product
development and related activities. The Company's products have been developed
primarily by the Company's internal development staff and, in some instances,
with the assistance of external consultants. Certain technologies have been
acquired and
 
                                      39
<PAGE>
 
integrated into Company's products through licensing arrangements. The Company
expects that most of its new products will be developed internally. However,
the Company will evaluate on an ongoing basis externally developed
technologies and products for integration into its product lines.
 
  The Company expects that development activities with respect to its database
connectivity products will include development of VisiODBC SDKs, VisiODBC
drivers and test suites compliant with the ODBC 3.0 specification as well as
additional features for its VisiChannel products, including high performance
scalability, message and queuing capabilities, a server-procedure architecture
and Simple Network Management Protocol ("SNMP") agents and other management
and monitoring tools. The Company intends to support the JDBC API through a
JDBC-to-ODBC product that will allow Java programmers using the JDBC API to
access heterogeneous data sources through the Company's VisiODBC Drivers or
VisiChannel products. Visigenic also expects to ship a VisiChannel Client
implementation in Java in the second half of fiscal 1997.
 
  The Company expects to enhance its VisiBroker for C++ and VisiBroker for
Java products and expand its distributed object connectivity product line. The
Company is developing an object-oriented transaction processing system based
on the Object Transaction Service ("OTS") specified by the OMG that enables
mission-critical On-line Transaction Process ("OLTP") applications. This
product is being jointly developed with Hitachi and is a combination of the
Company's VisiBroker for C++ product, the OTS interface implementations and
OpenTP1, Hitachi's advanced transaction processing engine. The Company
currently expects to release the product in the second half of fiscal 1997.
The Company also plans to leverage its CORBA expertise to develop products
that enable Microsoft's Active/X objects to interact with CORBA objects.
 
  The Company also intends to leverage its database connectivity expertise to
provide integrated database connectivity capabilities for its VisiBroker
product line. The Company's VisiBroker products would then provide a more
complete distributed object solution, addressing both the distributed object
and data connectivity requirements of its customer base.
 
  As of June 30, 1996, there were 51 employees on the Company's research and
development staff. The Company's product development expenditures in fiscal
1995, fiscal 1996 and the first quarter of fiscal 1997 were $3.2 million, $4.3
million and $1.7 million, respectively. The Company expects that it will
continue to commit substantial resources to product development in the future.
 
  The markets for the Company's products are characterized by rapid
technological developments, evolving industry standards, swift changes in
customer requirements, computer operating environments and software
applications, and frequent new product introductions and enhancements. As a
result, the Company's success depends substantially upon its ability to
anticipate changes and continue to enhance its existing products, develop and
introduce in a timely manner new products incorporating technological
advances, comply with emerging industry standards and meet increasing customer
expectations. If the Company is unable to develop and introduce new products
or enhancements to existing products in a timely manner in response to
changing market conditions or customer requirements, the Company's business,
operating results and financial condition would be materially and adversely
affected. See "Risk Factors--Need to Develop New Software Products and
Enhancements" and "--Dependence on Java; Risks Associated with Encryption
Technology."
 
COMPETITION
 
  The Company's products are targeted at the emerging markets for standards-
based database connectivity software and standards-based distributed object
connectivity software. The markets for the Company's products are intensely
competitive, subject to rapid change and significantly affected by new product
introductions and other market activities of industry participants. The
Company believes that the principal competitive factors in these markets are
product quality, performance and price, vendor and product reputation, product
architecture and quality of support.
 
                                      40
<PAGE>
 
  In the standards-based database connectivity market, the Company competes
principally against Intersolv. The Company's database connectivity products
also indirectly compete against proprietary database connectivity solutions
from database vendors. In the standards-based distributed object connectivity
market, the Company competes principally against two private companies, Iona
and Expersoft. The Company's distributed object connectivity products also
compete against existing or proposed distributed object connectivity solutions
from hardware vendors such as DEC, Hewlett-Packard, IBM and Sun. In addition,
because there are relatively low barriers to entry in the software market and
because the Company's products are based on publicly available standards, the
Company expects to experience additional competition in the future from other
established and emerging companies if the market for database connectivity and
distributed object connectivity software continues to develop and expand. In
particular, relational database vendors including Informix, Microsoft, Oracle
and Sybase may offer standards-based database connectivity software to their
customers, eliminating or reducing demand for the Company's products.
Similarly, operating system vendors such as DEC, Hewlett-Packard, IBM,
Microsoft and Sun may offer standards-based distributed object connectivity
products bundled with their operating systems. For instance, Microsoft has
announced plans to introduce DCOM, which would eliminate the need for CORBA-
compliant ORBs, such as those offered by the Company, for Microsoft operating
systems. Many of these current and potential competitors have well-established
relationships with the current and potential customers of the Company, have
extensive knowledge of the markets serviced by the Company, better name
recognition and more extensive development, sales and marketing resources and
are capable of offering single vendor solutions. As a result, these current
and potential competitors may be able to respond more quickly to new or
emerging technologies and changes in customer requirements, or to devote
greater resources to the development, promotion and sale of their products,
than the Company. It is also possible that new competitors or alliances among
competitors may emerge and rapidly acquire significant market share. The
Company also expects that competition will increase as a result of software
industry consolidations.
 
  The Company expects that it will face increasing pricing pressures from its
current competitors and new market entrants. Increased price competition may
result in price reductions, reduced gross margins and loss of market share,
any of which could materially adversely affect the Company's business,
financial condition or results of operations. There can be no assurance that
the Company will be able to compete successfully against current and future
competitors or that competitive pressures will not materially and adversely
affect its business, financial condition or results of operations. See "Risk
Factors--Intense Competition."
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
  The Company's success is dependent in part upon its proprietary technology.
While the Company relies on a combination of copyright and trademark laws,
trade secrets, confidentiality procedures and contractual provisions to
protect its proprietary rights, the Company believes that factors such as the
technical and creative skills of its personnel, new product developments,
frequent product enhancements, name recognition and reliable products and
product support are more essential to establishing and maintaining a
technology leadership position, particularly because the Company is supplying
standards-based products. The Company seeks to protect its software, published
data, documentation and other written materials under trade secret and
copyright laws, which afford only limited protection. The Company has granted
limited access to its source code to third parties under confidentiality
obligations. 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 distributes its products
electronically through the Internet. Distributing the Company's products
through the Internet makes the Company's software more
 
                                      41
<PAGE>
 
susceptible to unauthorized copying and use. The Company has historically
allowed and currently intends to continue to allow customers to electronically
download its client and server software. If as a result of changing legal
interpretations of liability for unauthorized use of the Company's software or
otherwise, users were to become less sensitive to avoiding copyright
infringement, the Company's business, results of operations and financial
condition could be materially adversely affected.
 
  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 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. 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, results of
operations and financial condition.
 
  In addition, the Company 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. The
Company licenses from Microsoft the base technology for the VisiODBC SDK
products and licenses from RSA security technology it plans to use in several
of its future products. Microsoft has the right to terminate its license with
the Company any time after delivery to the Company of the Microsoft SDK for
ODBC 3.0, which is expected to occur in the second half of 1996. The Company's
license with RSA may only be terminated for breach. The Company has entered
into a joint technology agreement with JavaSoft, a subsidiary of Sun
MicroSystems, that grants the Company the right to sub-license JavaSoft's JDBC
test suites and ODBC bridge. There can be no assurances that such firms will
remain in business, that they will continue to support their technology or
that their technology will otherwise continue to be available to the Company
on commercially reasonable terms. The loss of or inability to maintain any of
these software licenses could result in delays or cancellations in product
shipments until equivalent software can be identified and licensed or
developed and integrated with the Company's products. Any such delay or
cancellation could materially adversely affect the Company's business, results
of operations and financial condition. See "Risk Factors--Dependence on
Company and Third Party Proprietary Technology."
 
EMPLOYEES
 
  As of June 30, 1996, the Company employed 109 full time personnel, including
51 in product development, 7 in technical support, 37 in sales and marketing
and 14 in finance and administration. See "Risk Factors--Dependence on Key
Personnel; Need to Increase Technical, Sales and Marketing and Managerial
Personnel."
 
FACILITIES
 
  The Company's principal executive offices and research and development
facilities are located in San Mateo, California and consist of approximately
25,000 square feet under leases that will expire between July 2000 and January
2001. The Company also leases approximately 5,000 square feet of additional
office space, previously used for research and development activities by
PostModern, in Mountain View, California pursuant to a lease that terminates
July 31, 1996. The Company has sales offices in Atlanta, Boston, Dallas and
the Washington D.C. area and in Paris, France. The Company anticipates that it
will require additional space in the near term and that such space will be
available on reasonable terms.

office until the next annual meeting of stockholders or until their successors
are duly elected and qualified. The Amended and Restated Bylaws which will
become effective upon consummation of this offering will provide that,
beginning with the first annual meeting of stockholders following this
offering, the Board of Directors will be divided into three classes, with each
class serving staggered three-year terms. There are no family relationships
among the directors or executive officers of the Company.
 
  In April 1996, the Board of Directors established an Audit Committee and a
Compensation Committee. The Audit Committee oversees actions taken by the
Company's independent auditors, recommends the engagement of auditors and
reviews the Company's internal audits. The Compensation Committee approves the
compensation of executives of the Company and makes recommendations to the
Board of Directors with respect to standards for setting compensation levels.
The Compensation Committee also administers the Company's employee stock
option and stock purchase plans. See "--Stock Plans."

(1)  Options granted in fiscal 1996 are immediately exercisable and generally
     vest over five years, with 10% of the option shares becoming fully vested
     six months from the initial vesting date and 1/60th of the option shares
     vesting each successive month, with full vesting occurring on the fifth
     anniversary of the initial vesting date. The Company has a repurchase
     right for shares not vested. Under the terms of the Company's 1995 Stock
     Option Plan (the "Option Plan"), the Board or a committee of the Board
     retains discretion, subject to Option Plan limits, to modify the terms of
     outstanding options and to reprice outstanding options. The options have
     a term of ten years, subject to earlier termination in certain situations
     related to termination of employment. See "--Stock Plans" for a
     description of the material terms of the options.
(2)  Based on a total of 832,500 options granted to all employees and
     consultants during fiscal 1996.
(3)  All options were granted at an exercise price equal to the fair market
     value of the Company's Common Stock as determined by the Board of
     Directors of the Company on the date of grant. The Company's Common Stock
     was not publicly traded at the time of the option grants to the officers.
   
(4)  Potential realizable values are calculated based on the exercise price of
     $0.40 per share and are net of exercise price, but before taxes
     associated with exercise. Amounts represent hypothetical gains that could
     be achieved for the respective options if exercised at the end of the
     option term. The assumed 5% and 10% annual rates of stock price
     appreciation from the date of grant to the end of the option term are
     provided in accordance with rules of the Securities and Exchange
     Commission and do not represent the Company's estimate or projection of
     the future Common Stock price. Actual gains, if any, on stock option
     exercises are dependent on the future performance of the Common Stock,
     overall market conditions and the option holders' continued employment
     through the vesting period. This table does not take into account any
     actual appreciation in the price of the Common Stock from the date of
     grant to the present. Assuming the fair market value of the Common Stock
     at the date of grant is the initial public offering price of $10.00, the
     potential realizable value of these options (a) at a 5% assumed annual
     rate of stock price appreciation from the date of this offering would be
     $397,224, $198,612, $198,612 and $198,612 for Mr. Hanson's options,
     $119,167, $158,889 and $158,889 for Ms. Langlais' options, $39,722 and
     $119,167 for Mr. Shewmake's options, and $79,445 and $158,889 for Mr.
     Gerould's options and (b) at a 10% assumed annual rate of stock price
     appreciation from the date of this offering would be $638,436, $319,218,
     $319,218 and $319,218 for Mr. Hanson's options, $191,531, $255,374 and
     $255,374 for Ms. Langlais' options, $63,844 and $191,531 for Mr.
     Shewmake's options, and $127,687 and $255,374 for Mr. Gerould's options.

(1)  These options are immediately exercisable in full at the date of grant,
     but shares purchased on exercise of unvested options are subject to a
     repurchase right in favor of the Company which lapses ratably over five
     years and entitles the Company to repurchase unvested shares at their
     original issuance price.
(2)  Calculated on the basis of the fair market value of the underlying
     securities as of March 31, 1996 of $0.40 per share, as determined by the
     Company's Board of Directors, minus the aggregate exercise price.
 
  No options to purchase the Company's Common Stock were exercised during the
fiscal year ended March 31, 1996 by the Named Executive Officers. No
compensation intended to serve as incentive for performance to occur over a
period longer than one fiscal year was paid pursuant to a long-term incentive
plan during the last fiscal year to any Named Executive Officer. The Company
does not have any defined benefit or actuarial plan under which benefits are
determined primarily by final compensation (or average final compensation) and
years of service with any of the Named Executive Officers.
 
STOCK PLANS
 
  1995 Stock Option Plan. The 1995 Stock Option Plan of the Company (the
"Option Plan") provides for the grant of stock options to employees (including
officers), directors and consultants of the Company and its subsidiaries.
Options may be incentive stock options within the meaning of Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code") or nonstatutory
stock options, although incentive stock options may be granted only to
employees. All options granted under the Option Plan must be granted by April
18, 2005.
 
  The Option Plan is administered by the Board of Directors or a committee
thereof. Subject to the provisions of the Option Plan, the Board or committee
has the authority to select the persons to whom options are granted and
determine the terms of each option, including (i) the number of shares of
Common Stock covered by the option, (ii) when the option becomes exercisable,
(iii) the option exercise price, which, in the case of incentive stock
options, must be at least 100% of the fair market value of a share of Common
Stock as of the date of grant, and, in the case of nonstatutory stock options
must be at least 85% of the fair market value of a share of Common Stock as of
the date of grant, and (iv) the duration of the option (which, in the case of
incentive stock options, may not exceed ten years). Generally, options granted
under the Option Plan are immediately exercisable but remain subject to
repurchase by the Company until vested under a schedule established by the
Board or committee. The Company's repurchase right will terminate upon certain
changes in control of the Company unless the outstanding options are assumed
or replaced by the acquiring corporation or if, following certain changes in
control of the Company, the option holder is terminated without cause or
resigns following "constructive termination" as defined in the Option Plan.
All incentive stock options are nontransferable other than by will or the laws
of descent and distribution. With the Company's consent, nonstatutory stock
options may be transferred to an optionee's immediate family, a trust for his
or her benefit or a partnership in which only the optionee and immediate
family members are partners.
 
                                      47
<PAGE>
 
  Of the 2,500,000 shares of Common Stock reserved for issuance under the
Option Plan as of June 30, 1996, a total of 225,501 shares had been issued
upon the exercise of options, of which 134,716 remain subject to repurchase,
options for the purchase of a total of 1,087,500 shares at a weighted average
exercise price of $2.24 per share were outstanding and 1,186,999 shares were
available for future option grants.
   
  1996 Outside Directors Stock Option Plan. In June 1996, the Board of
Directors, subject to stockholder approval, adopted the 1996 Outside Directors
Stock Option Plan (the "Directors Plan") and reserved a total of 200,000
shares of Common Stock for issuance thereunder. Stockholder approval of the
Directors Plan will be sought prior to the closing of the offering. The
Directors Plan provides for the grant of nonstatutory stock options to
nonemployee directors of the Company. The Directors Plan is designed to work
automatically without administration; however, to the extent administration is
necessary, it will be performed by the Board of Directors. The Directors Plan
provides that each future nonemployee director of the Company will be granted
an option to purchase 15,000 shares of Common Stock on the date on which the
optionee first becomes a nonemployee director of the Company and each current
nonemployee director will be granted an option to purchase 15,000 shares of
Common Stock on the date following the first annual meeting of the
stockholders of the Company after this offering (the "Initial Grant").
Thereafter, on each anniversary of a nonemployee director's Initial Grant, the
director will be granted an additional option to purchase 5,000 shares of
Common Stock (an "Annual Grant"). Subject to an optionee's continuous service
with the Company, 1/8th of an Initial Grant will become exercisable six months
after the date of grant and 1/48th of the Initial Grant will become
exercisable monthly thereafter. Each Annual Grant will become exercisable in
twelve monthly installments beginning in the 37th month after the date of
grant, subject to the optionee's continuous service. The exercise price per
share of all options granted under the Directors Plan will equal the fair
market value of a share of Common Stock on the date of grant. Options granted
under the Directors Plan will have a term of ten years. In the event of
certain changes in control of the Company, options outstanding under the
Directors Plan will become immediately exercisable and vested in full. With
the Company's consent, the options may be transferred to an optionee's
immediate family, a trust for their benefit or a partnership in which only the
optionee and immediate family members are partners.     
 
  1996 Employee Stock Purchase Plan. In June 1996, the Board of Directors,
subject to stockholder approval, adopted the 1996 Employee Stock Purchase Plan
(the "Purchase Plan") and reserved a total of 450,000 shares of Common Stock
for issuance thereunder, none of which have been issued as of the effective
date of this offering. The Purchase Plan, which is intended to qualify under
Section 423 of the Code, is administered by the Board of Directors or by a
committee thereof. Employees (including officers and employee directors) of
the Company or any subsidiary designated by the Board for participation in the
Purchase Plan are eligible to participate in the Purchase Plan if they are
customarily employed for more than 20 hours per week and more than five months
per year, and do not own 5% or more of the Company's Common Stock. The
Purchase Plan will be implemented by sequential six-month offerings, the first
of which will commence on the effective date of this offering. The initial
offering period will terminate on January 31, 1997. Thereafter, offering
periods will begin on February 1 and August 1 of each year. The Board may
change the dates or duration of one or more offerings, but no offering may
exceed 27 months. The Purchase Plan permits eligible employees to purchase
Common Stock through payroll deductions at a price no less than 85% of the
lower of the fair market value of the Company's Common Stock on the first day
or the last day of each six-month offering period. Participants generally may
not purchase more than 1,500 shares in a six-month offering period or stock
having a value (measured at the beginning of the offering) greater than
$25,000 in any calendar year. In the event of certain changes in control of
the Company, the Board may accelerate the purchase of shares under the
Purchase Plan unless the acquiring corporation assumes or replaces the
purchase rights outstanding under the Purchase Plan.
 
  Executive Performance Incentive Plan. Under the Company's Executive
Performance Incentive Plan (the "Incentive Plan"), the Compensation Committee
of the Board of Directors (the "Committee") may award performance units to
designated executives that will vest and become payable if one or more
preestablished performance goals are attained during a specified performance
period and the participant remains an employee. Performance goals may be
either absolute or relative (in comparison to a standard determined by the
Committee)
 
                                      48
<PAGE>
 
measures of revenue, operating income, net income, earnings per share, or
departmental expenses. Performance units are dollar-denominated in an amount
specified by the Committee at the time of initial award and become payable at
a time determined by the Committee following its certification of the
attainment of the performance goals. Participants may elect to receive payment
of vested performance units either in cash or in shares of the Company's
Common Stock having a fair market value on the date of payment equal to the
dollar value of the vested performance units. Immediately prior to certain
changes in control of the Company, Incentive Plan participants will be paid
the value of their performance units for the current performance period that
would have vested had the performance goals been attained at the target level,
prorated, however, for the portion of the performance period elapsed prior to
the change in control.
 
COMPENSATION OF DIRECTORS
 
  Directors of the Company do not receive cash for services provided as a
director. Directors are reimbursed for all travel and related expenses
incurred in connection with attending board and committee meetings. Upon
adoption of the Directors Plan, directors who are not employees of the Company
will receive yearly grants of options to purchase Common Stock. The Directors
Plan will become effective upon consummation of this offering. See "--Stock
Plans--1996 Outside Directors Stock Option Plan."
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION IN COMPENSATION
DECISIONS
 
  The Compensation Committee was formed in April 1996, and is composed of
Roger J. Sippl, J. Sidney Webb and Eric Young. No interlocking relationship
exists between any member of the Company's Compensation Committee and any
member of any other company's board of directors or compensation committee.
During the fiscal year completed March 31, 1996, the Board of Directors of the
Company, of which Roger J. Sippl, Chief Executive Officer of the Company, was
and is a member, fulfilled all functions of the Compensation Committee with
regard to compensation of executive officers of the Company.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
  Pursuant to the provisions of the Delaware General Corporation Law, the
Company has adopted provisions in its Certificate of Incorporation, as
amended, which provide that directors of the Company shall not be personally
liable for monetary damages to the Company or its stockholders for a breach of
fiduciary duty as a director, except for liability as a result of: (i) a
breach of the director's duty of loyalty to the Company or its stockholders;
(ii) acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law; (iii) an act related to the unlawful
stock repurchase or payment of a dividend under Section 174 of Delaware
General Corporation Law; and (iv) transactions from which the director derived
an improper personal benefit. Such limitation of liability does not affect the
availability of equitable remedies such as injunctive relief or rescission.
 
  The Company's Certificate of Incorporation, as amended, also authorizes the
Company to indemnify its officers, directors and other agents, by bylaws,
agreements or otherwise, to the full extent permitted under Delaware law. The
Company intends to enter into separate indemnification agreements with its
directors and officers which may, in some cases, be broader than the specific
indemnification provisions contained in the Delaware General Corporation Law.
The indemnification agreements may require the Company, among other things, to
indemnify such officers and directors against certain liabilities that may
arise by reason of their status or service as directors or officers (other
than liabilities arising from willful misconduct of a culpable nature), to
advance their expenses incurred as a result of any proceeding against them as
to which they could be indemnified, and to obtain directors' and officers'
insurance if available on reasonable terms. The Company believes that the
provisions and agreements are necessary to attract and retain qualified
directors and officers.
 
  The Company's Amended and Restated Bylaws provide that the Company shall
indemnify its directors and officers and may indemnify its employees to the
fullest extent permitted by law. The Company believes that indemnification

  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.
 
  At present, there is no pending litigation or proceeding involving a
director, officer, employee or agent of the Company where indemnification will
be required or permitted. The Company is not aware of any threatened
litigation or proceeding which may result in a claim for such indemnification.

                         DESCRIPTION OF CAPITAL STOCK
 
  Upon consummation of this offering, the authorized capital stock of the
Company will consist of 50,000,000 shares of Common Stock and 2,000,000 shares
of Preferred Stock, par value $0.001 per share. Each outstanding share of
Preferred Stock will be automatically converted into one share of Common Stock
upon the closing of the offering being made hereby. Upon such conversion, such
Preferred Stock will be canceled, retired and eliminated from the shares that
the Company is authorized to issue. The following summary of certain
provisions of the Common Stock and the preferred stock of the Company does not
purport to be complete and is subject to, and qualified in its entirety by,
the Certificate of Incorporation and By-Laws of the Company that are included
as exhibits to the Registration Statement of which this Prospectus forms a
part and by the provisions of applicable law.
 
COMMON STOCK
 
  As of June 30, 1996, there were approximately 10,469,971 shares of Common
Stock outstanding held of record by 160 stockholders, as adjusted to reflect
the conversion of the outstanding shares of Preferred Stock and convertible
promissory notes upon the closing of the offering. The holders of Common Stock
are entitled to one vote for each share held of record on all matters
submitted to a vote of the holders of Common Stock. Subject to preferences
applicable to any outstanding preferred stock, holders of Common Stock are
entitled to receive ratably such dividends as may be declared by the Board of
Directors out of funds legally available therefor. In the event of a
liquidation, dissolution or winding up of the Company, the holders of Common
Stock are entitled to share ratably in all assets remaining after payment of
liabilities and the liquidation preference of any preferred stock. Holders of
Common Stock have no preemptive or subscription rights, and there are no
redemption or conversion rights with respect to such shares. All outstanding
shares of Common Stock are fully paid and non-assessable, and the shares of
Common Stock to be issued upon completion of the offering will be fully paid
and non-assessable.
 
PREFERRED STOCK
 
  The Board of Directors has the authority, without action by the
stockholders, to designate and issue preferred stock in one or more series and
to designate the dividend rate, voting rights and other rights, preferences
and restrictions of each series any or all of which may be greater than the
rights of the Common Stock. It is not possible to state the actual effect of
the issuance of any shares of preferred stock upon the rights of holders of
the Common Stock until the Board of Directors determines the specific rights
of the holders of such preferred stock. However, the effects might include,
among other things, restricting dividends on the Common Stock, diluting the
voting power of the Common Stock, impairing the liquidation rights of the
Common Stock and delaying or preventing a change in control of the Company
without further action by the stockholders. The Company has no present plans
to issue any shares of preferred stock.
 
REGISTRATION RIGHTS
 
  Following the sale of the shares of Common Stock offered hereby, the holders
of approximately 6,789,050 shares: issuable upon conversion of the outstanding
shares of Preferred Stock and outstanding convertible notes; held by the
founder and certain early employees of the Company; and held by former
PostModern shareholders, and their transferees, will have certain rights to
register those shares under the Securities Act of 1933, as amended. These
rights are provided under the terms of an agreement among the Company and the
holders of such shares. If the Company registers any of its Common Stock
either for its own account or for the account of other security holders, the
holders of such shares are entitled to include their shares of Common Stock in
the registration, subject to the ability of the underwriters to limit the
number of shares included in the offering. All fees, costs and expenses of
such registrations (other than underwriting discounts and commissions) will be
borne by the Company.

DELAWARE LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS
 
  The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203"), which, subject to certain exceptions, prohibits a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three (3) years following the date that
such stockholder became an interested stockholder, unless: (i) prior to such
date, the board of directors of the corporation approved either the business
combination or the transaction that resulted in the stockholder becoming an
interested stockholder; (ii) upon consummation of the transaction that
resulted in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned (x) by persons
who are directors and also officers and (y) by employee stock plans in which
employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or
exchange offer; or (iii) on or subsequent to such date, the business
combination is approved by the board of directors and authorized at an annual
or special meeting of stockholders, and not by written consent, by the
affirmative vote of at least 66 2/3% of the outstanding voting stock that is
not owned by the interested stockholder.
 
  Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii)
any sale, transfer, pledge or other disposition of 10% or more of the assets
of the corporation involving the interested stockholder; (iii) subject to
certain exceptions, any transaction that results in the issuance or transfer
by the corporation of any stock of the corporation to the interested
stockholder; (iv) any transaction involving the corporation that has the
effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder; or
(v) the receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or
through the corporation. In general, Section 203 defines an interested
stockholder as any entity or person beneficially owning 15% or more of the
outstanding voting stock of the corporation and any entity or person
affiliated with or controlling or controlled by such entity or person.
   
  The Company's Restated Certificate of Incorporation, which will become
effective upon consummation of this offering, will require that any action
required or permitted to be taken by stockholders of the Company must be
effected at a duly called annual or special meeting of the stockholders and
may not be effected by a consent in writing. In addition, special meetings of
the stockholders of the Company may be called only by the Board of Directors
or certain officers of the Company. The Restated Certificate of Incorporation
which will become effective upon consummation of this offering will provide
that, beginning with the first annual meeting of stockholders following this
offering, the Board of Directors will be divided into three classes, with each
class serving staggered three-year terms, that a director may be removed from
the Board of Directors only for cause and only upon the vote of at least 66
2/3% of the voting power of all outstanding stock, and that certain amendments
of the Company's Restated Certificate of Incorporation, and all amendments by
the stockholders of the Company's Amended and Restated Bylaws, require the
approval of holders of at least 66 2/3% of the voting power of all outstanding
shares. These provisions may have the effect of deferring hostile takeovers or
delaying changes in control or management of the Company.     
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Common Stock is The First National
Bank of Boston.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no public market for the Common
Stock. Future sales of substantial amounts of Common Stock in the public
market could adversely affect the market price of the Common Stock.
 
  Upon completion of this offering, the Company will have outstanding an
aggregate of 12,169,971 shares of Common Stock, assuming (i) the issuance of
2,100,000 shares of Common Stock offered hereby, (ii) no exercise of the
Underwriters' over-allotment option and (iii) no exercise of options to
purchase Common Stock after June 30, 1996. Of these shares, the 2,100,000
shares sold in the offering will be freely tradeable without restriction or
further registration under the Securities Act of 1933, as amended (the
"Securities Act"), except for any shares purchased by "affiliates" of the
Company as that term is defined in Rule 144 under the Securities Act (whose
sales would be subject to certain limitations and restrictions described
below).
 
  The remaining 10,069,971 shares of Common Stock held by existing
stockholders were issued and sold by the Company in reliance on exemptions
from the registration requirements of the Securities Act. All such outstanding
shares will be subject to the "lock-up" agreements described below on the date
of this Prospectus. Upon expiration of lock-up agreements 180 days after the
date of this Prospectus, 8,048,789 shares will become eligible for sale,
subject in most cases to the limitations of Rule 144. The remaining 2,021,182
shares held by existing stockholders will become eligible for sale at various
times over a period of less than two years and could be sold earlier if the
holders exercise registration rights. In addition, holders of stock options
could exercise these options and sell certain of the shares issued upon
exercise as described below.
 
  As of June 30, 1996, there were a total of 1,087,500 shares of Common Stock
subject to outstanding options under the Option Plan, all of which were
exercisable. However, these shares are subject to lock-up agreements. All
options held by officers and directors of the Company are subject to a 180 day
lock-up agreement described below, and all other options are subject to a 180
day lock-up agreement with the Company.
 
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least
two years (including the holding period of any prior owner except an
affiliate) is entitled to sell in "broker's transactions" or to market makers,
within any three-month period commencing 90 days after the date of this
prospectus, a number of shares that does not exceed the greater of (i) one
percent of the number of shares of Common Stock then outstanding
(approximately 121,700 shares immediately after this offering) or (ii)
generally, the average weekly trading volume in the Common Stock during the
four calendar weeks preceding the required filing of a Form 144 with respect
to such sale. Sales under Rule 144 are generally subject to the availability
of current public information about the Company. Under Rule 144(k), a person
who is deemed not to have been an affiliate of the Company at any time during
the 90 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for a least three years, is entitled to sell such shares
without having to comply with the manner of sale, public information, volume
limitation or notice filing provisions of Rule 144. Under Rule 701 under the
Securities Act, persons who purchase shares upon exercise of options granted
prior to the effective date of this offering are entitled to sell such shares
90 days after the effective date of this offering in reliance on Rule 144,
without having to comply with the holding period and notice filing
requirements of Rule 144 and, in the case of non-affiliates, without having to
comply with the public information, volume limitation or notice filing
provisions of Rule 144.
 
  The Company intends to file registration statements under the Securities Act
180 days after the effective date of the offering to register shares of Common
Stock reserved for issuance under the Option Plan and the Directors Plan, thus
permitting the resale of such shares by non-affiliates and by affiliates,
subject to Rule 144 volume limitations applicable thereto, in the public
market without restriction under the Securities Act. Such registration
statements will become effective immediately upon filing.
 
  As of June 30, 1996, the holders of approximately 6,789,050 shares are
entitled to certain registration rights with respect to such shares. If such
registration rights are exercised, the shares can be sold without any holding
period or sales volume limitation. If such holders, by exercising their
registration rights, cause a large number of
 
                                      59
<PAGE>
 
shares to be registered and sold in the public market, such sales could have
an adverse effect on the market price for the Company's Common Stock. If the
Company were required to include in a Company initiated registration the
shares held by such holders pursuant to the exercise of their registration
rights, such sales might have an adverse effect on the Company's ability to
raise needed capital. See "Description of Capital Stock--Registration Rights."
 
  All existing stockholders of the Company have agreed that they will not,
subject to certain limited exceptions, directly or indirectly, offer, sell or
otherwise dispose of any shares of Common Stock or any securities convertible
into or exchangeable or exercisable for any such shares for a period of 180
days after the effective date of the offering without the prior written
consent of the Company, and in most cases, Hambrecht & Quist LLC.

</TABLE>
 
  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent, including the absence of any
material adverse change in the Company's business and the receipt of certain
certificates, opinions and letters from the Company and its counsel and
independent auditors. The nature of the Underwriters' obligation is such that
they are committed to purchase all shares of Common Stock offered hereby if
any of such shares are purchased.
 
  The Underwriters propose to offer the shares of Common Stock directly to the
public at the initial public offering price set forth on the cover page of
this Prospectus and to certain dealers at such price less a concession not in
excess of $    per share. The Underwriters may allow and such dealers may
reallow a concession not in excess of $    per share to certain other dealers.
After the initial public offering of the shares, the offering price and other
selling terms may be changed by the Representatives.
 
  The Company and the Selling Stockholders have granted to the Underwriters an
option, exercisable no later than 30 days after the date of this Prospectus,
to purchase up to 255,000 and 60,000, respectively, additional shares of
Common Stock at the initial public offering price, less the underwriting
discount, set forth on the cover page of this Prospectus. To the extent that
the Underwriters exercise this option, each of the Underwriters will have a
firm commitment to purchase approximately the same percentage thereof which
the number of shares of Common Stock to be purchased by it shown in the above
table bears to the total number of shares of Common Stock offered hereby. The
Company and the Selling Stockholders will be obligated, pursuant to the
option, to sell shares to the Underwriters to the extent the option is
exercised. The Underwriters may exercise such option only to cover-allotments
made in connection with the sale of shares of Common Stock offered hereby.
 
  The offering of the shares is made for delivery when, as and if accepted by
the Underwriters and subject to prior sale and to withdrawal, cancellation or
modification of the offering without notice. The Underwriters reserve the
right to reject an order for the purchase of shares in whole or in part.
 
  The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, and to contribute to payments the Underwriters may be required
to make in respect thereof.
 
  The Selling Stockholders and the other stockholders of the Company,
including the executive officers and directors, who will own in the aggregate
10,069,971 shares of Common Stock after this offering, have agreed that they
will not, without the prior written consent of Hambrecht & Quist LLC, offer,
sell or otherwise dispose of any shares of Common Stock, options or warrants
to acquire shares of Common Stock or securities exercisable
 
                                      61
<PAGE>
 
for or convertible into shares of Common Stock owned by them during the 180-
day period following the effective date of the Registration Statement for this
offering. The Company has agreed that it will not, without the prior written
consent of Hambrecht & Quist LLC, offer, sell or otherwise dispose of any
shares of Common Stock, options or warrants to acquire shares of Common Stock
or securities exchangeable for or convertible into shares of Common Stock
during the 180-day period following the effective date of the Registration
Statement for this offering, except that the Company may grant additional
options under its stock plans and issue securities under, or pursuant to the
exercise of options granted under, its stock plans. See "Shares Eligible for
Future Sale."
 
  The Representatives currently anticipate that up to 105,000 shares of Common
stock may be sold at the initial public offering price to directors (or their
affiliated entities) and employees of the Company who have expressed an
interest in purchasing such shares of Common Stock in the offering. The number
of shares available for sale to the general public will be reduced to the
extent such persons purchase such shares. Any such shares not so purchased
will be offered by the Representatives to the general public on the same basis
as other shares offered hereby.
 
  The Representatives have informed the Company that the Underwriters do not
intend to confirm sales of Common Stock offered hereby to any accounts over
which they have discretionary authority.
 
  Prior to this offering, there has been no public market for the Common
Stock. The initial public offering price of the Common Stock was determined by
negotiation among the Company, the representatives of the Selling Stockholders
and the Representatives. Among the factors considered in determining the
initial public offering price were prevailing market and economic conditions
revenues and earnings of the Company, market valuations of other companies
engaged in activities similar to the Company, estimates of the business
potential and prospects of the Company, the present state of the Company's
business operations, the Company's management and other factors deemed
relevant.

matters will be passed upon for the Company by Gray Cary Ware & Freidenrich, A

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Visigenic Software, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Visigenic
Software, Inc. (a Delaware corporation) and subsidiary as of March 31, 1995
and 1996 and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended March
31, 1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 financial position of Visigenic Software, Inc.
and subsidiary as of March 31, 1995 and 1996, and the results of their
operations and their cash flows for each of the three years in the period
ended March 31, 1996 in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                                MARCH 31, 1996
     (INFORMATION RELATING TO THE QUARTERS ENDED JUNE 30, 1995 AND 1996 IS
                                  UNAUDITED)
 
1. ORGANIZATION AND OPERATIONS OF THE COMPANY:
   
  Visigenic Software, Inc. (the "Company") was incorporated on February 12,
1993. The Company operates in a single industry segment and is involved in the
design, development and marketing of database connectivity software products.
Through March 31, 1995 the Company's principal efforts were focused on raising
capital, developing its products and applications, establishing marketing and
sales channels and recruiting key personnel. During fiscal 1996, the Company
emerged from the development stage, however, the Company continues to be
subject to the risks associated with companies in a comparable stage of
development including, but not limited to, dependence on key personnel;
limited operating history and a history of losses; and the need to develop new
software products and product enhancements.     
 
  Although the Company was incorporated on February 12, 1993, its activities
during the first two months involved limited cash expenditures and consisted
only of recruiting of key personnel and raising capital. Accordingly, the
accompanying consolidated statements of operations, stockholders' equity and
cash flows for the year ended March 31, 1994 are presented for the period from
inception (February 12, 1993) to March 31, 1994.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Principles of Consolidation and Functional Currency
 
  The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiary after elimination of intercompany transactions
and balances. The functional currency of the Company's foreign subsidiary is
the U.S. dollar. Foreign exchange gains and losses resulting from the
remeasurement of the financial statements for the subsidiary, which are not
material, are included in other income in the accompanying consolidated
statements of operations.
 
 Use of Estimates in Preparation of Financial Statements
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported results of operations during the reporting period.
Actual results could differ from those estimates.
 
 Cash Equivalents and Short-Term Investments
 
  The Company considers all highly liquid investments with an original
maturity of three months or less from the date of purchase to be cash
equivalents. The Company's short-term investments are accounted for pursuant
to the provisions of Statement of Financial Accounting Standards (SFAS) No.
115, "Accounting for Certain Investments in Debt and Equity Securities." As of
March 31, 1995 and 1996, the Company's cash and cash equivalents were
deposited in checking and money market accounts, U.S. Government Treasury
Bills and certificates of deposits.
 
 Software Development Costs
 
  In accordance with SFAS No. 86, "Accounting for the Costs of Computer
Software to be Sold, Leased, or Otherwise Marketed," the Company capitalizes
eligible computer software development costs upon the establishment of
technological feasibility, which it has defined as completion of a working
model. For the years ended March 31, 1994, 1995 and 1996, the amount of costs
eligible for capitalization, after consideration of factors such as realizable
value, were not material and, accordingly, all software development costs have
been charged to product development expense in the accompanying consolidated
statements of operations.

 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the estimated useful lives of the assets (or
over the lease term if it is shorter for leasehold improvements), which range
from three to five years. Property and equipment consists of the following (in

 Revenue Recognition and Deferred Revenue
 
  The Company's revenue is derived from fixed license fees from licensing its
products, royalties from VARs, ISVs and distributors, and fees for services
related to its products, including software maintenance, development contracts
and consulting and training. Certain of the Company's license arrangements
with VARs and ISVs provide for sublicense fees payable to the Company based on
a percentage of the VAR's or ISV's net revenue. Other license arrangements
provide for fixed license fees for the right to make and distribute an
unlimited number of copies of the Company's product for a specified period of
time. Ongoing sublicense fee revenue, other than from guaranteed sublicense
fees, is recognized when it is reported by the VAR, ISV or distributor.
Service revenue is primarily attributable to lower margin maintenance and
other revenue, including training revenue and engineering development fees.
 
  The Company generally recognizes revenue from fixed license and guaranteed
sublicense fees upon delivery of software products if there are no significant
post-delivery obligations, if collection is probable and if the license
agreement requires payment within 90 days. If significant post-delivery
obligations exist or if a product is subject to customer acceptance, revenue
is deferred until no significant obligations remain or acceptance has
occurred.
 
  Maintenance revenue from ongoing customer support and product upgrades is
recognized ratably over the term of the applicable maintenance period, which
is typically 12 months. If maintenance is included in a license agreement,
such amounts are unbundled from the license fee at its fair market value.
Consulting and training revenue is generally recognized as services are
performed over the term of the agreement. Revenue from engineering development
work is generally recognized on a percentage of completion basis. If a
transaction includes both license and service elements, license fee revenue is
recognized upon shipment of the software, provided services do not include
significant customization or modification of the base product and payment
terms are not subject to acceptance criteria. In cases where license fee
payments are contingent upon the acceptance of services, revenues from both
the license and service elements are deferred until the acceptance criteria
are met.
 
  Deferred revenue consists primarily of the unrecognized portion of revenue
under maintenance and support contracts (which revenue is deferred and
recognized ratably over the term of such contract) and advance payment of
software development fees and license fees.

 Significant Customers and Related Parties
 
  A relatively small number of customers have accounted for a significant
percentage of the Company's total revenue. The following four customers
accounted for more than 10% of total revenue:

  Customers C and D are related parties as they were purchasers of Series C
convertible preferred stock in May 1996 and are also holders of the
convertible notes payable to stockholders (see Note 9). Accounts receivable
from these related parties as of June 30, 1996 totalled approximately $1.4
million.
 
 Export Sales
 
  The Company markets its products in North America and in foreign countries
(primarily Europe and Japan) through its sales personnel, VARs, ISVs and
distributors. For fiscal 1996, export sales, which consist of domestic sales
to customers in foreign countries, were 10% of total revenue. For fiscal 1995
and for the quarter ended June 30, 1996 export sales were less than 10% of
total revenue.
 
 Concentration of Credit Risk
 
  Financial instruments which potentially subject the Company to a
concentration of credit risk consist principally of accounts receivable. As of
March 31, 1996, approximately 75% of accounts receivable were concentrated
with ten customers. The Company generally does not require collateral on
accounts receivable as the majority of the Company's customers are large, well
established companies. The Company provides reserves for credit losses, which
to date have been insignificant.
 
 New Accounting Standard
 
  In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, "Accounting for Stock-Based Compensation," which will be effective for
the Company's 1997 fiscal year. SFAS No. 123 allows companies which have
stock-based compensation arrangements with employees to adopt a new fair-value
basis of accounting for stock options and other equity instruments or to
continue to apply the existing accounting rules under Accounting Principles
Board (APB) Opinion No. 25, "Accounting for Stock Issued to Employees," but
with additional financial statement disclosure. The Company expects to
continue to account for stock-based compensation arrangements under APB
Opinion No. 25 and, therefore, does not expect SFAS No. 123 to have a material
impact on its financial position, results of operations and cash flows.
 
 Pro Forma Net Loss per Share
 
  Pro forma net loss per share is computed using the pro forma weighted
average number of common and common equivalent shares outstanding during the
period. Common equivalent shares consist of convertible preferred stock (using
the if converted method) and stock options (using the treasury stock method).
Common stock options are excluded from the computation if their effect is
antidilutive. Convertible preferred stock outstanding during the period is
included (using the if converted method) in the computation of common
equivalent shares even though the effect is antidilutive. Also, pursuant to
the Securities and Exchange Commission Staff Accounting Bulletins and staff
policy, such computations include all common and common equivalent shares
issued within the 12 months preceding the filing date of this registration
statement as if they were outstanding for all periods presented. Historical
net loss per share amounts have not been presented since such amounts are not
deemed meaningful due to the significant change in the Company's capital
structure that will occur in connection with the proposed offering.

 Unaudited Interim Financial Data
 
  The unaudited interim financial statements as of June 30, 1996 and for the
quarters ended June 30, 1995 and 1996 have been prepared on the same basis as
the audited financial statements and, in the opinion of management, include
all adjustments (consisting only of normal recurring adjustments) necessary to
present fairly the financial information set forth therein, in accordance with
generally accepted accounting principles. The data disclosed in the notes to
the consolidated financial statements for these periods are unaudited. The
results of operations for the quarter ended June 30, 1996 are not necessarily
indicative of the results to be expected for any future period.
 
3. LINE OF CREDIT:
 
  The Company has a $1.0 million revolving line of credit agreement (the
"Agreement") with a bank, which expires on August 15, 1996. Advances under the
Agreement bear interest at the bank's prime lending rate plus 1.25% (9.5% at
March 31, 1996), are limited to 80% of eligible accounts receivable and are
secured by substantially all of the assets and contractual rights of the
Company. The Agreement also contains certain financial restrictions and
covenants which require, among others, that the Company maintain a minimum
monthly tangible net worth, and a minimum monthly ratio of debt to equity. In
addition, the Agreement prohibits the Company from paying dividends without
prior bank consent. As of March 31 and June 30, 1996, the Company was in
compliance with the financial covenants. There were no borrowings outstanding
under the Agreement as of March 31, 1996. As of June 30, 1996, the Company had
borrowed $524,000 under the Agreement.
 
4. COMMITMENTS:
 
  The Company leases its facilities under operating lease agreements expiring
through January 2001. Rent expense for all operating leases totaled
approximately $131,000, $192,000 and $304,000 for the years ended March 31,
1994, 1995 and 1996, respectively. Minimum future lease payments under all
noncancellable operating leases as of March 31, 1996 were as follows (in
thousands):

5. CONVERTIBLE PREFERRED STOCK:
 
  In June 1996, the Company's Board of Directors approved a one-for-two
reverse split of its common and preferred stock. All common and preferred
share and per share amounts in the accompanying consolidated financial
statements have been adjusted retroactively to give effect to this reverse
stock split.
 
  In conjunction with the proposed initial public offering of the Company's
common stock, all outstanding shares of convertible preferred stock will
automatically convert into common stock upon closing of the offering. The pro
forma effects of this conversion, including the Series C preferred stock and
convertible notes payable to stockholders issued in May and June 1996 (see
Note 9), have been reflected in the accompanying consolidated balance sheet as
of June 30, 1996.
 
  The Company's certificate of incorporation, as amended in May 1996,
authorizes the issuance of up to 10,000,000 shares of convertible preferred
stock, of which the Company has designated 1,606,000 shares as

Series A preferred stock, 6,000,000 shares as Series B preferred stock and
1,000,000 shares as Series C preferred stock. The rights and preferences of
the Series A, B and C preferred stock are as follows:
 
 Dividends
 
  The holders of Series A, B and C preferred stock are entitled to receive
dividends when and as declared by the Board of Directors. No cash dividends
can be paid on common stock or preferred stock unless, at the same time, a
dividend is paid with respect to all outstanding shares of preferred stock in
an amount for each such share equal to the aggregate amount of such dividends
payable on that number of shares of common stock into which each such share of
preferred stock could then be converted.
 
 Liquidation Preference
 
  In the event of any liquidation, dissolution or winding up of the Company,
holders of Series A, B and C preferred stock are entitled to receive, in
preference to holders of common stock, the amount of $2.40, $4.00 and $9.00
per share, respectively. Such amounts will be adjusted for any stock split,
combination, distribution or dividend. After payment of the above amounts,
holders of common stock are entitled to receive the amount of $2.40 per share,
adjusted for any stock split, combination, distribution or dividend. After
payment of the above amounts, holders of Series A preferred stock and common
stock are entitled to receive the amount of $1.60 per share for each share of
such stock, adjusted for any stock split, combination, distribution or
dividend. Any remaining assets would then be distributed ratably among
stockholders in proportion to their aggregate preferential amounts.
 
 Voting Rights
 
  The holders of preferred stock are entitled to the number of votes equal to
the number of shares of common stock into which such preferred stock is
convertible.
 
 Conversion
 
  Each share of preferred stock is convertible into one share of common stock,
at the option of the holder thereof, at any time after the date of issuance.
The conversion rate is subject to adjustment for dilution, including, but not
limited to, stock splits, stock dividends and stock combinations. In addition,
each share of Series A, B and C preferred stock will automatically convert
into common stock at the then conversion rate upon the written consent of
holders of a majority of all outstanding Series A, B and C preferred stock or
upon the closing of an underwritten public offering of the Company's common
stock at an aggregate offering price of not less than $10,000,000 and at an
offering price per share of at least $4.00 per share, of at least $6.67 per
share and of at least $12.00 per share, for Series A, B and C preferred stock,
respectively. Holders of Series C preferred stock have agreed to reduce the
automatic conversion price of the Series C preferred stock if necessary to
cause such stock to convert automatically into shares of common stock upon the
completion of the Company's initial public offering.
 
6. COMMON STOCK:
 
  In June 1996, the Company's Board of Directors approved a one-for-two
reverse split of its common and preferred stock. All common and preferred
share and per share amounts in the accompanying consolidated financial
statements have been adjusted retroactively to give effect to this reverse
stock split.
 
  Prior to July 1993, the Company issued 232,575 shares of common stock to
certain employees and directors of the Company that are subject to certain
repurchase rights. These rights of repurchase lapse over a five-year period.
As of March 31, 1996, 64,228 shares of common stock are subject to repurchase
by the Company at prices ranging from $.08 to $.20 per share.

 Stock Purchase Plans
 
  In April 1993 and August 1994, the Company adopted Stock Purchase Plans (the
"Plans") and authorized the issuance of 952,500 shares thereunder to employees
and consultants. Stock purchased under these Plans generally vests ratably
over a five-year period. Unvested shares may be repurchased by the Company at
the original issuance price in the event of termination.
 
  As of March 31, 1996, 526,287 shares were issued and outstanding under these
Plans at prices ranging from $.20 to $.40 per share, which was the fair market
value of the common stock, as determined by the Board of Directors, on the
date of grant, of which 289,522 were subject to repurchase. As of March 31,
1996, no further shares were available for issuance under the Plans.
 
 Stock Option Plan
 
  In fiscal 1996, the Company established the 1995 Stock Option Plan (the
"1995 Plan") and reserved 2,000,000 shares of common stock for issuance. Under
the 1995 Plan, the Board of Directors may grant incentive and nonqualified
stock options to employees, consultants and directors of the Company. The
exercise price per share for an incentive stock option cannot be less than the
fair market value, as determined by the Board of Directors, on the date of
grant. The exercise price per share for nonqualified stock options cannot be
less than 85% of the fair market value, as determined by the Board of
Directors, on the date of grant. Options generally expire ten years after the
date of grant and vest over a period of five years. Option activity under the
1995 Plan was as follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
7. EMPLOYEE BENEFIT PLAN:
 
  In June 1995, the Company adopted the Visigenic Software, Inc. 401(k) Plan
(the "401(k) Plan"), as allowed under Section 401(k) of the Internal Revenue
Code, which provides for tax deferred salary deductions for eligible employees
of the Company. Employees who are 21 years of age or older are eligible to
participate immediately upon the date of hire and may make voluntary
contributions of their compensation to the 401(k) Plan. The 401(k) Plan does
not provide for Company contributions and the Company is the administrator.
 
8. INCOME TAXES:
 
  The Company accounts for income taxes pursuant to SFAS No. 109, "Accounting
for Income Taxes." SFAS No. 109 requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns based upon
enacted tax laws and rates applicable to the periods in which taxes become
payable. A valuation allowance has been recorded for the entire deferred tax
asset as a result of uncertainties regarding realization of the asset
including the limited operating history of the Company, the lack of
profitability to date and the uncertainty over future operating profitability.
Components of the net deferred tax asset are as follows (in thousands):

carryforwards of approximately $9.8 million and $2.0 million, respectively,
which expire at various dates through 2011. In addition, as of March 31, 1996,
the Company had general business credit carryforwards of approximately
$372,000 which expire at various dates through 2011.
 
  Under current tax law, net operating loss and credit carryforwards available
in any given year may be limited upon the occurrence of certain events,
including significant changes in ownership interests.
 
9. SUBSEQUENT EVENTS:
 
 Acquisition of PostModern Computing Technologies Inc.
 
  In May 1996, the Company completed the acquisition of PostModern, a
developer of distributed object connectivity software. In the acquisition,
which was structured as a merger, the Company issued 3,099,821 shares of its
common stock, valued at $3.00 per share based on an independent appraisal of
the Company's common stock, and paid a total of $2.3 million in exchange for
all of PostModern's outstanding shares. The Company also incurred acquisition-
related costs of approximately $450,000, resulting in a total purchase price
of approximately $13.1 million. In addition, the Company made cash payments,
subject to one-year vesting and totaling $1.5 million, to certain PostModern
employees. The acquisition of PostModern was accounted for as a purchase in
the quarter ended June 30, 1996.

                           VISIGENIC SOFTWARE, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In connection with the purchase price allocation, the Company received an
appraisal of the intangible assets which indicated that approximately $12.0
million of the acquired intangible assets consisted of in process product
development. Because there can be no assurance that the Company will be able
to successfully complete the development and integration of the PostModern
products or that the acquired technology has any alternative future use, the
acquired in process product development was charged to expense by Visigenic in
its quarter ended June 30, 1996.
 
  As a result of the purchase price allocation, the excess of the purchase
price over net assets acquired is $1.1 million, which is being amortized on a
straight-line basis over a period of two years. Management believes that the
unamortized balance is recoverable through future operating results.
 
  In connection with the acquisition, the Company also assumed PostModern's
outstanding stock options and reserved 361,785 shares of the Company's common
stock for issuance upon exercise of such options at an exercise price of $0.24
to $0.60 per share under similar vesting terms.
 
 Issuance of Series C Convertible Preferred Stock and Convertible Notes
   
  On May 24, 1996, the Company sold 444,444 shares of its Series C preferred
stock at a price of $9.00 per share to three investors, for aggregate proceeds
of $4.0 million. The Company has the right to require these investors to
purchase up to an additional $4.0 million in convertible notes at any time
prior to October 31, 1996. If the Company has not completed an initial public
offering of its Common Stock by August 30, 1996, in order to require the
purchase of these convertible notes after September 30, 1996, the Company must
achieve revenue of at least $3.6 million for the quarter ended September 30,
1996. Between May 28 and June 7, 1996, the Company issued convertible notes,
bearing interest at the rate of 8.25% per annum, for $2.0 million of the
available $4.0 million. The principal amount of the notes and all accrued
interest are due and payable 3 years after the issuance date. However, upon
the closing of the Company's initial public offering, the principal amount of
each note and all accrued interest will automatically convert into shares of
the Company's common stock at the lesser of $13.00 per share or the offering
price per share to the public, and the Series C preferred stock will
automatically convert into shares of the Company's common stock. The Company
used a portion of the proceeds from the sale of the Series C preferred stock
and the convertible notes to pay amounts payable in connection with the
acquisition of PostModern.     
 
 1996 Employee Stock Purchase Plan
 
  The Company's 1996 Employee Stock Purchase Plan (the "Purchase Plan") was
adopted by the Company's Board of Directors in June 1996, subject to approval
by the stockholders. A total of 450,000 shares of common stock has been
reserved for issuance under the Purchase Plan. The Purchase Plan permits
eligible employees to purchase common stock at 85% of the lower of the fair
market value of the Company's common stock on the first day or the last day of
each six-month offering period.
 
 1996 Outside Directors Stock Option Plan
 
  The Company's 1996 Outside Directors Stock Option Plan (the "Directors
Plan") was adopted by the Company's Board of Directors in June 1996, subject
to approval by the stockholders. A total of 200,000 shares of common stock has
been reserved for issuance under the Directors Plan. The Directors Plan
provides for the initial grant of nonstatutory stock options to purchase
15,000 shares of common stock on the earlier of the first annual meeting
following the initial public offering of the Company's common stock or the
date on which the optionee first becomes a nonemployee director of the
Company, and an additional option to purchase 5,000 shares of common stock on
the next anniversary to existing and future nonemployee directors of the
Company. The exercise price per share of all options granted under the
Directors Plan will equal the fair market value of a share of the Company's
common stock on the date of grant of the option.

1. THE COMPANY:
 
  PostModern Computing Technologies Inc. (the "Company") was incorporated in
October 1991 in California. The Company, which is closely held, operates in a
single industry segment and is involved in the design, marketing and support
of distributed object connectivity software.
 
  In May 1996, the Company was acquired by Visigenic Software, Inc.
("Visigenic"), a Delaware corporation, according to the terms of an agreement
which provides that the Company be merged with and into Visigenic (the
"Acquisition"). In connection with the Acquisition, Visigenic issued 3,099,821
shares of its common stock and paid cash consideration of approximately $2.3
million in exchange for all of the outstanding shares of common stock of the
Company and assumed all issued and outstanding options to purchase common
stock of the Company. In addition, at the closing of the Acquisition,
Visigenic made cash payments to certain employees of the Company totaling $1.5
million, subject to one-year vesting. The Acquisition was structured as a tax-
free exchange according to Section 368(a)(II)(E) of the Internal Revenue Code.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Revenue Recognition
 
  The Company generates revenue from licensing the rights to use its software
products, sales of post-contract support, development contracts, consulting
services and training services performed for customers who license its
products.
 
  Revenue from software license agreements is recognized upon shipment of the
software if there are no significant post-delivery obligations and collection
is probable. If an acceptance period is required, revenue is recognized upon
the earlier of customer acceptance or the expiration of the acceptance period.
Revenue from post-contract support services is recognized ratably over the
term of the support period. Consulting revenue is primarily related to
development and customization services performed on a time and material basis
under separate service and consulting arrangements. Revenue from development
contracts and training services is recognized as the services are performed
over the term of the agreement. In cases where license fee payments are
contingent upon the acceptance of services, revenue from both the license and
the service elements is deferred until the acceptance criteria are met.
 
 Significant Customers
 
  For fiscal 1994, 1995 and 1996, the combined revenue from five customers
accounted collectively for 96%, 88% and 83% of total revenue, respectively.
The following customers accounted for more than 10% of total revenue:

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Export Revenue
 
  Export revenue for fiscal 1996, which consisted of sales to a customer in
Japan, was 12% of total revenue. Export revenue was less than 10% of total
revenue for fiscal 1994 and 1995.
 
 Concentration of Credit Risk
 
  Financial instruments which potentially subject the Company to a
concentration of credit risk consist principally of accounts receivable. As of
March 31, 1996, approximately 72% of accounts receivable were concentrated
with five customers. The Company believes that its credit and collection
procedures are adequate to monitor and evaluate risk among its customer base.
For fiscal 1994, 1995 and 1996 credit losses have been insignificant.
 
 Software Development Costs
 
  The Company capitalizes eligible software development costs upon the
establishment of technological feasibility, which the Company has defined as
completion of a working model. For fiscal 1994, 1995 and 1996, costs which
were eligible for capitalization, after consideration of factors such as
realizable value, were insignificant and, thus, the Company has charged all
software development costs to research and development expense in the
accompanying statements of operations.
 
 Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is computed using
the double declining balance method over the estimated useful lives of the
assets of five to seven years.
 
 Use of Estimates in Preparation of Financial Statements
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reporting amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported results of operations during the reporting period.
Actual results could differ from those estimates.
 
3. COMMITMENTS:
 
  The Company leases its office space under a non-cancelable operating lease
which expires on March 31, 1998. Rent expense for all operating leases was
approximately $23,000, $38,000 and $38,000 for fiscal 1994, 1995 and 1996,
respectively. Future minimum lease payments under all non-cancelable operating
leases are as follows:

4. LINE OF CREDIT:
 
  In December 1995, the Company entered into a line of credit agreement (the
"Agreement") with a bank which allows for borrowings of up to $125,000 and
expires in December 1996. Advances under the Agreement, which are secured by
substantially all of the Company's assets and contractual rights of the
Company, bear interest at the bank's prime lending rate plus 1.0% (9.25% at
March 31, 1996). As of March 31, 1996, there were no borrowings outstanding
under the Agreement.

5. STOCK OPTION PLAN:
 
  In November 1995, the Company established the 1995 Stock Option Plan (the
"Plan") and reserved 1,980,000 shares of common stock for issuance thereunder.
Under the Plan, the Board of Directors may grant incentive stock options to
employees and directors at the fair market value of the shares, as determined
by the Board of Directors, on the date of grant. The exercise price per share
for nonqualified stock options cannot be less than 85% of fair market value of
the shares, as determined by the Board of Directors, on the date of grant.
Options generally expire ten years after the date of grant and vest over a
period of four years. Activity under the Plan is summarized as follows:

</TABLE>
 
  As of March 31, 1996, options to purchase 826,250 shares of common stock at
prices ranging from $0.10 to $0.25 were fully vested and exercisable. In
connection with the Acquisition, Visigenic assumed all outstanding options of
the Company.
 
6. INCOME TAXES:
 
  Through December 31, 1995, the Company was an S corporation. Effective
January 1, 1996, the Company changed to C corporation status. Federal and
state income tax regulations require that the income or loss of an S
corporation be included in the tax returns of the individual shareholders.
Accordingly, no provision for taxes is made in the accompanying financial
statements for fiscal 1994, 1995 and for the period from April 1, 1995 to
December 31, 1995.
 
  The Company accounts for income taxes pursuant to SFAS No. 109, "Accounting
for Income Taxes." SFAS No. 109 provides for an asset and liability approach
to accounting for income taxes under which deferred income taxes are provided
based upon enacted tax laws and rates applicable to the periods in which taxes
become payable. The provision for income taxes for the year ended March 31,
1996 was as follows:

  In May 1996, Visigenic Software, Inc. (the "Company" or "Visigenic")
completed the acquisition of PostModern Computing Technologies Inc., a
California corporation ("PostModern"). PostModern is a developer of
distributed object software. The acquisition of PostModern has been accounted
for as a purchase.
 
  The accompanying pro forma condensed combined statement of operations for
the fiscal year ended March 31, 1996 and the quarter ended June 30, 1996
assumes that the acquisition took place as of the beginning of fiscal 1996,
and combines Visigenic's and PostModern's statements of operations for each
Company's respective fiscal year ended March 31, 1996 and quarters ended June
30, 1996. The historical financial statements of PostModern for the quarter
ended June 30, 1996 only include two months of operations as it was merged
into Visigenic effective May 31, 1996. The pro forma condensed combined
statement of operations for the fiscal year ended March 31, 1996 does not
include the effect of any nonrecurring charges directly attributable to the
acquisition.
 
  The purchase price allocation reflected in the accompanying pro forma
condensed combined financial statements has been prepared on an estimated
basis. The effects resulting from any differences in the final allocation of
the purchase price are not expected to have a material effect on the Company's
financial statements.
 
  The accompanying pro forma condensed combined financial statements should be
read in conjunction with the historical financial statements and related notes
thereto for both Visigenic and PostModern, which are included in this
Prospectus.

          NOTES TO PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
NOTE 1. PRO FORMA ADJUSTMENTS
 
  Certain pro forma adjustments have been made to the accompanying pro forma
condensed combined statements of operations as described below:
 
  (a) Reflects the amortization of the excess of the purchase price over net
      assets acquired of approximately $1.1 million, which will be amortized
      on a straight line basis over its estimated life of two years, and $1.5
      million of cash payments made to certain PostModern employees subject
      to one-year vesting.
 
  (b) Reflects the elimination of the PostModern tax provision for fiscal
      1996 due to the pro forma 1996 net loss.
 
  (c) Pro forma weighted average common and common equivalent shares do not
      include common stock equivalents as inclusion of these shares would be
      anti-dilutive. The stand alone Visigenic and the pro forma combined
      weighted average common and common equivalent shares are identical as
      the Visigenic shares issued to PostModern shareholders are included in
      the stand alone Visigenic weighted average share calculation pursuant
      to the Securities and Exchange Commission Staff Accounting Bulletin No.
      83.
 
NOTE 2. PURCHASE PRICE ALLOCATION
 
  In connection with the acquisition, the Company exchanged 3,099,821 shares
of its common stock, valued at $3.00 per share based on an independent
appraisal of the Company's stock, and paid cash consideration of approximately
$2.3 million in exchange for all of the outstanding shares of common stock of
PostModern. The Company also incurred acquisition related costs of
approximately $450,000 resulting in a total purchase price of approximately
$13.1 million. In addition to the forgoing, at the closing of the acquisition,
the Company made cash payments to certain PostModern employees totaling $1.5
million. In the event that such employees leave the Company within the 12
months following the date of acquisition, the employees must refund back to
the Company a pro rata portion of the payment for the months they are no
longer employees.
 
  In connection with the purchase price allocation, the Company received an
appraisal of the intangible assets which indicated that approximately $12.0
million of the acquired intangible assets consisted of in process product
development. Because there can be no assurance that the Company will be able
to successfully complete the development and integration of the PostModern
products or that the acquired technology has any alternative future use, the
acquired in process product development was charged to expense by Visigenic in
its quarter ended June 30, 1996 and is reflected in the accompanying pro forma
statement of operations for the quarter ended June 30, 1996.
 
  As a result of the purchase price allocation, the excess of the purchase
price over net assets acquired is $1.1 million, which is being amortized on a
straight-line basis over a period of two years. Management believes that the
unamortized balance is recoverable through future operating results.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
  Section 145 of the Delaware General Corporation Law permits indemnification
of officers, directors, and other corporate agents under certain circumstances
and subject to certain limitations. The Company's Certificate of
Incorporation, as amended, and Bylaws provide that the Company shall indemnify
its directors, officers, employees and agents to the full extent permitted by
Delaware General Corporation Law, including in circumstances in which
indemnification is otherwise discretionary under Delaware law. In addition,
the Company intends to enter into separate indemnification agreements with its
directors, officers and certain employees which would require the Company,
among other things, to indemnify them against certain liabilities which may
arise by reason of their status or service (other than liabilities arising
from willful misconduct of a culpable nature) and to maintain directors' and
officers' liability insurance, if available on reasonable terms.
 
  These indemnification provisions and the indemnification agreement to be
entered into between the Company and its officers and directors may be
sufficiently broad to permit indemnification of the Company's officers and
directors for liabilities (including reimbursement of expenses incurred)
arising under the Securities Act.
 
  The Underwriting Agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of the Company and
its officers and directors for certain liabilities arising under the
Securities Act, or otherwise.

ITEM 17. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions referenced in Item 14 of
this Registration Statement or otherwise, the Registrant has been advised that
in the opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Securities Act, and is,
therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the
Registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered hereunder, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
  The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective; and
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of Prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at the time shall be
  deemed to be the initial bona fide offering thereof.

       (Originally incorporated under the same name on February 12, 1993)

(hereinafter sometimes referred to as the "Corporation").

     SECOND:  The address of the registered office of the Corporation in
     ------                                                             
the State of Delaware is 15 East North Street, in the City of Dover, County of
Kent.  The name of the registered agent of the Corporation at that address is

     THIRD:  The purpose of the Corporation is to engage in any lawful act
     -----                                                                
or activity for which a corporation may be organized under the General
Corporation Law of Delaware.

     FOURTH:  The Corporation is authorized to issue a total of fourteen
     ------                                                             
million (14,000,000) shares of stock in two classes designated respectively
"Preferred Stock" and "Common Stock."  The total number of shares of Preferred
Stock the Corporation shall have authority to issue is four million (4,000,000),
par value one-tenth of one cent ($.001) per share, and the total number of
shares of Common Stock the Corporation shall have authority to issue is ten
million (10,000,000), par value one-tenth of one cent ($.001) per share.

     The Corporation's Board of Directors (the "Board") is authorized, subject
to any limitations prescribed by law, to provide for the issuance of the shares
of Preferred Stock in series, and by filing a certificate pursuant to the
applicable law of the state of Delaware, to establish from time to time the
number of shares to be included in each such series, and to fix the designation,
powers, preferences, and rights of the shares of each such series and any
qualifications, limitations or restrictions thereof. The number of authorized
shares of any class of capital stock of the Corporation may be increased or

                                       1
<PAGE>
 
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the outstanding Common Stock of
the Corporation, without the approval of the holders of the Preferred Stock, or
of any series thereof, unless the approval of any such holders is required
pursuant to the certificate or certificates establishing any series of Preferred
Stock.

     FIFTH:  A director of this Corporation shall not be personally liable
     -----                                                                
to the Corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law, or (iv) for any transaction from which the director derived an
improper personal benefit.

     If the Delaware General Corporation Law is hereafter amended to authorize
corporate action further eliminating or limiting the personal liability of a
director, then the liability of a director of the Corporation, without any
further corporate action on the part of the Corporation, shall be eliminated or
limited to the fullest extent permitted by the Delaware General Corporation Law,
as so amended.

     Any repeal or modification of the foregoing provisions of this Article
SIXTH by the stockholders of the Corporation shall not adversely affect any
right or protection of a director of the Corporation existing at the time of
such repeal or modification.

     SIXTH:  The authorized number of directors initially shall be one (1)
     -----                                                                
and, thereafter, shall be fixed from time to time exclusively by the Board
pursuant to a resolution adopted by a majority of the total number of authorized
directors (whether or not there exist any vacancies in previously authorized
directorships at the time any such resolution is presented to the Board for
adoption).  The holders of Common Stock will be entitled to elect, voting
together as a single group with the holders of any series of Preferred Stock
that is entitled to vote with the Common Stock in such election, a majority of
the directors (other than any directors who are separately elected by any series
of Preferred Stock) (the "Majority Directors"), and holders of Common Stock will
be entitled to elect, voting together as a single group with the holders of any
series of Preferred Stock that is entitled to vote with the Common Stock in such
election, the remaining directors (other than any directors who are separately
elected by any series of Preferred Stock) (the "Minority Directors").  In any
election of Majority Directors or Minority Directors by the stockholders of the
Corporation, each holder of shares of Common Stock shall have one vote per
share, and each holder of shares of any series of Preferred Stock that has the
right to vote in such election shall be entitled to such number of votes as is
set forth in the certificate establishing the powers, preferences and rights of
such series.  Vacancies and newly-created directorships resulting from any
increase in the authorized number of directors shall only be filled by the vote
of a

                                       2
<PAGE>
 
majority of directors elected by holders of shares of the class, classes or
series of stock of the Corporation entitled to elect directors to such vacant or
newly-created directorship.

     SEVENTH:  The Board is expressly empowered to adopt, amend or repeal
     -------                                                             
Bylaws of the Corporation.  Any adoption, amendment or repeal of Bylaws of the
Corporation by the Board shall require the approval of a majority of the total
number of authorized directors (whether or not there exist any vacancies in
previously authorized directorships at the time any resolution providing for any
such adoption, amendment or repeal is presented to the Board).  The stockholders
shall also have power to adopt, amend or repeal the Bylaws of the Corporation.

     EIGHTH:  Elections of directors need not be by written ballot.
     ------            
 
     NINTH:  This Corporation reserves the right to amend, alter, change or
     -----                                                                 
repeal any provision contained in this Restated Certificate of Incorporation, in
the manner now or hereafter prescribed by statute, and all rights conferred upon
stockholders herein are granted subject to this reservation.

     TENTH:  Whenever a compromise or arrangement is proposed between
     -----                                                           
this Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this Corporation under the provisions of Section 279 of Title 8 of the
Delaware Code order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this Corporation, as the case may
be, to be summoned in such manner as the said court directs.  If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may be,
and also on this Corporation.

                           CERTIFICATE OF DESIGNATION

                     Pursuant to Section 151 of the General
                    Corporation Law of the State of Delaware

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

                            SERIES A PREFERRED STOCK


     Very Visual Software, Inc., a Delaware corporation (the "Corporation"),
hereby certifies that the following resolution has been duly adopted by the
Board of Directors of the Corporation:

     RESOLVED, that pursuant to the authority expressly granted to and vested in
the Board of Directors of the Corporation (the "Board") by the provisions of the
Restated Certificate of Incorporation of the Corporation (the "Certificate of
Incorporation"), there hereby is created, out of the 4,000,000 shares of
Preferred Stock, par value $0.001 per share, of the Corporation authorized in
Article FOURTH of the Certificate of Incorporation (the "Preferred Stock"), a
series of the Preferred Stock of the Corporation consisting of 1,606,000 shares,
which series shall have the following powers, designations, preferences and
relative, participating, optional and other rights, and the following
qualifications, limitations and restrictions:

          1.  Designation and Amount.
              ---------------------- 

     This series of Preferred Stock shall be designated the Series A Preferred
Stock (the "Series A Preferred Stock"), and the authorized number of shares
constituting such series shall be 1,606,000. The par value of the Series A
Preferred Stock shall be $0.001 per share.

          2.  Dividend Rights of Series A Preferred Stock.  Subject to the
              -------------------------------------------                 
dividend provisions fixed by the Board for any series of Preferred Stock
designated by the Board in the future, the holders of Series A Preferred Stock
shall be entitled to receive dividends, out of any assets at the time legally
available therefor, when and as declared by the Board.  No cash dividends shall
be paid on any Common Stock unless at the same time a dividend is paid with
respect to all outstanding shares of Series A Preferred Stock in an amount for
each such share of Series A Preferred Stock equal to the aggregate amount of
such dividends payable on that number of shares of Common Stock into which each
such share of Series A Preferred Stock could then be converted.

<PAGE>
 
          3.  Preference on Liquidation.
              ------------------------- 

     Subject to the liquidation preferences of any series of Preferred Stock
other than the Series A Preferred Stock, including, without limitation, any
liquidation preference prior to any liquidation preference set forth in this
Section 2, in the event of any liquidation, dissolution or winding up of the
Corporation, distributions to holders of Series A Preferred Stock and holders of
Common Stock shall be made in the following manner:

               (a) The holders of Series A Preferred Stock shall be entitled to
receive, prior and in preference to any distribution of any of the assets of the
Corporation to the holders of the Common Stock by reason of their ownership of
such stock, the amount of $1.20 per share for each share of Series A Preferred
Stock then held by them, adjusted for any stock split, stock combination, stock
distribution or stock dividend with respect to such shares. If the assets and
funds available for distribution among the holders of Series A Preferred Stock
and among the holders of any series of Preferred Stock ranking on a parity with
the Series A Preferred Stock with respect to this subsection (a) of Section 2 as
to the distribution of assets and funds upon such dissolution, liquidation or
winding up shall be insufficient to permit the payment to such holders of their
full liquidation payments, then the entire assets and funds of the Corporation
legally available for such distribution shall be distributed ratably among such
holders in proportion to their aggregate preferential amounts.

               (b) After payment in full to the holders of Series A Preferred
Stock of all amounts exclusively payable on or with respect to said shares
pursuant to subsection (a) of this Section 3, the holders of the Common Stock
shall be entitled to receive, prior and in preference to any further
distribution of any of the assets of the Corporation to its stockholders, the
amount of $1.20 per share for each share of Common Stock then held by them,
adjusted for any stock split, stock combination, stock distribution or stock
dividend with respect to such shares. If the assets and funds available for
distribution among the holders of the Common Stock and among the holders of any
series of Preferred Stock ranking on a parity with the Common Stock with respect
to this subsection (b) of Section 2 as to the distribution of assets upon such
dissolution, liquidation or winding up shall be insufficient to permit the
payment to such holders of their full liquidation payments, then the entire
remaining assets and funds of the Corporation legally available for such
distribution shall be distributed ratably among such holders in proportion to
their aggregate preferential amounts.

               (c) After payment in full to the holders of Common Stock of all
amounts exclusively payable on or with 

                                       3
<PAGE>
 
respect to said shares pursuant to subsection (b) of this Section 3, the
remaining assets of the Corporation, if any, shall be distributed ratably among
the holders of Series A Preferred Stock, among the holders of Common Stock and
among the holders of any series of Preferred Stock ranking on a parity with the
Series A Preferred Stock and Common Stock with respect to this subsection (c) of
Section 2 as to the distribution of assets upon dissolution, liquidation or
winding up, on an "as converted" basis. For purposes of determining
distributions under this Section 3(c), the term "as converted" shall mean that
Series A Preferred Stock and any Liquidation Parity Stock shall be deemed to
have been converted into Common Stock at the Conversion Price in effect for
Series A Preferred Stock and the conversion price in effect for any Liquidation
Parity Stock, respectively, on the record date for such distribution.

          4.  Redemption.
              ---------- 
     
     (a) At any time and from time to time after March 31, 1994, the Corporation
may, at the option of the Board, and out of assets at the time legally available
therefor, redeem all or part (selected pro rata from among all of the shares of
Series A Preferred Stock) of the outstanding shares of Series A Preferred Stock
at the redemption price set forth in Section 4(b) below, provided that the
Corporation shall give written notice by mail, postage prepaid, to the holders
of the Series A Preferred Stock to be redeemed at least twenty (20) days prior
to the date specified for redemption (a "Redemption Date"). The notice shall
further call upon such holders to surrender to the Corporation on or before the
Redemption Date at the place designated in the notice such holder's certificate
or certificates representing the shares to be redeemed and shall state that, in
lieu of redemption, a holder may, prior to the Redemption Date, convert its
Series A Preferred Stock into Common Stock in accordance with Section 6 below.
On or after the Redemption Date, each holder of shares of Series A Preferred
Stock called for redemption shall surrender the certificate evidencing such
shares to the Corporation, except that such number of shares shall be reduced by
the number of shares which have been converted into Common Stock between the
date of notice and the Redemption Date, at the place designated in such notice
and shall thereupon be entitled to receive payment of the Redemption Price.

     (b) The Series A Preferred Stock may be redeemed at a cash price equal to
$1.20 per share, adjusted for any stock split, stock combination, stock
distribution or stock dividend with respect to such shares.

     (c) From and after the Redemption Date, unless there shall have been a
default in payment of the Redemption Price, all rights of the holders with
respect to such redeemed shares of Series A Preferred Stock (except the right to
receive the 

                                       4
<PAGE>
 
Redemption Price without interest upon surrender of their certificate) shall
cease and such shares shall not thereafter be transferred on the books of this
Corporation or be deemed to be outstanding for any purpose whatsoever.

     (d) If the funds of the Corporation legally available for redemption of
shares of Series A Preferred Stock on the Redemption Date are insufficient to
redeem the total number of shares of Series A Preferred Stock to be redeemed,
the Corporation shall use those funds which are legally available to redeem the
maximum possible number of such shares ratably among the holders of such shares
to be redeemed. The shares of Series A Preferred Stock not redeemed shall remain
outstanding and entitled to all the rights and preferences provided herein.

          5.  Voting.
              ------ 

     Except as otherwise required by law, and except as otherwise provided in
the last sentence of Article FOURTH of the Certificate of Incorporation and in
Article SIXTH of the Certificate of Incorporation, the shares of Series A
Preferred Stock shall be voted together with the Common Stock at any annual or
special meeting of the stockholders of the Corporation, or may act by written
consent in the same manner as the Common Stock, and shall have the voting rights
and powers equal to the voting rights of the Common Stock, upon the following
basis: each holder of shares of Series A Preferred Stock shall be entitled to
such number of votes for the shares of Series A Preferred Stock held by him on
the record date for such meeting or action to be taken by written consent, as
shall be equal to the nearest whole number of shares of the Common Stock into
which such holder's shares of Series A Preferred Stock are convertible
immediately after the close of business on the record date for such meeting or
action to be taken by written consent, as the case may be. Holders of Series A
Preferred Stock will be entitled to vote on such basis with holders of Common
Stock in the election of the Minority Directors pursuant to Article SIXTH of the
Certificate of Incorporation.

          6. Conversion Rights. The holders of Series A Preferred Stock shall
             -----------------
have conversion rights as follows:

               (a) Each share of Series A Preferred Stock shall be convertible,
at the option of the holder thereof, at any time at the principal office of the
Corporation or any transfer agent for such shares, into fully paid and
nonassessable shares of Common Stock of the Corporation. The number of shares of
Common Stock into which each share of Series A Preferred Stock may be converted
shall be determined by dividing $1.20 by the Conversion Price determined as
hereinafter provided in effect at the time of the conversion. The Conversion
Price per share at which shares of Common Stock shall be initially issuable upon
conversion of 

                                       5
<PAGE>
 
any shares of Series A Preferred Stock shall be $1.20, subject to adjustment as
provided herein.

               (b) Each share of Series A Preferred Stock shall be converted
into Common Stock automatically in the manner provided herein upon the earlier
to occur of (i) the time holders of a majority of the outstanding shares of all
series of Preferred Stock which are subject to conversion upon the written
consent of holders of a majority of all outstanding shares of Preferred Stock
consent in writing to the conversion of all such outstanding Preferred Stock, or
(ii) immediately prior to the closing of the sale of securities of the
Corporation pursuant to a firm commitment underwritten public offering
registered with the Securities and Exchange Commission, other than on Form S-4,
or Form S-18, or any successor form thereto, with a public offering price of not
less than $2.00 per share (adjusted to reflect subsequent stock dividends, stock
splits, recapitalization and the like) and with aggregate gross proceeds of not
less than $5,000,000.

               (c) The holder of any shares of Series A Preferred Stock may
exercise the conversion right specified in Section 6(a) by surrendering to the
Corporation or any transfer agent of the Corporation the certificate or
certificates for the shares to be converted, accompanied by written notice
specifying the number of shares to be converted. Upon the occurrence of any
event specified in Section 6(b), the outstanding shares of Series A Preferred
Stock shall be converted automatically without any further action by the holders
of such shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent; provided that the
Corporation shall not be obligated to issue to any holder certificates
evidencing the shares of Common Stock issuable upon such conversion unless
certificates evidencing such shares of Series A Preferred Stock are delivered
either to the Corporation or any transfer agent of the Corporation. Conversion
shall be deemed to have been effected on the date when delivery of notice of an
election to convert and of certificates for shares being converted is made or on
the date of the occurrence of any event specified in Section 6(b), as the case
may be, and such date is referred to herein as the "Conversion Date." As
promptly as practicable thereafter (and after surrender of the certificate or
certificates representing shares of Series A Preferred Stock to the Corporation
or any transfer agent of the Corporation in the case of conversions pursuant to
Section 6(b)) the Corporation shall issue and deliver to such holder a
certificate or certificates for the number of full shares of Common Stock to
which such holder is entitled. No fractional shares of Common Stock shall be
issued by the Corporation and all such fractional shares shall be disregarded.
In lieu thereof, the Corporation shall pay in cash the fair market value of any
such fractional share as determined by the Board. The person in whose name the

                                       6
<PAGE>
 
certificate or certificates for Common Stock are to be issued shall be deemed to
have become a holder of record of such Common Stock on the applicable Conversion
Date.  Upon conversion of only a portion of the number of shares covered by a
certificate representing shares of Series A Preferred Stock surrendered for
conversion (in the case of conversion pursuant to Section 6(a)), the Corporation
shall issue and deliver to or upon the written order of the holder of the
certificate so surrendered for conversion, at the expense of the Corporation, a
new certificate covering the number of shares of Series A Preferred Stock
representing the unconverted portion of the certificate so surrendered.

               (d) In case the Corporation shall at any time (i) subdivide the
outstanding Common Stock, or (ii) issue a stock dividend on its outstanding
Common Stock, the number of shares of Common Stock issuable upon conversion of
Series A Preferred Stock immediately prior to such subdivision or the issuance
of such stock dividend shall be proportionately increased by the same ratio as
the subdivision or dividend (with appropriate adjustments in the Conversion
Price of Series A Preferred Stock). In case the Corporation shall at any time
combine its outstanding Common Stock, the number of shares of Common Stock
issuable upon conversion of Series A Preferred Stock immediately prior to such
combination shall be proportionately decreased by the same ratio as the
combination (with appropriate adjustments in the Conversion Price of Series A
Preferred Stock). All such adjustments described herein shall be effective at
the close of business on the date of such subdivision, stock dividend or
combination, as the case may be.

               (e) In case of any merger (other than a merger in which the
Corporation is not the continuing or surviving entity) or any reclassification
of the Common Stock of the Corporation, each share of the Series A Preferred
Stock shall thereafter be convertible into that number of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock issuable upon conversion of a share of Series A Preferred Stock
immediately prior to such merger or reclassification would have been entitled
upon such merger or reclassification.  In any such case, appropriate adjustment
(as determined by the Board) shall be made in the application of the provisions
herein set forth with respect to the rights and interests thereafter of the
holders of Series A Preferred Stock, such that the provisions set forth herein
shall thereafter be applicable, as nearly as reasonably may be, in relation to
any share of stock or other property thereafter issuable upon conversion.

               (f) The Corporation shall at all times reserve and keep
available, out of its authorized but unissued Common Stock, solely for the
purpose of effecting the conversion of

                                       7
<PAGE>
 
Series A Preferred Stock, the full number of shares of Common Stock deliverable
upon the conversion of all Series A Preferred Stock from time to time
outstanding. The Corporation shall from time to time (subject to obtaining
necessary director and stockholder authorizations), in accordance with the laws
of the State of Delaware, increase the authorized amount of its Common Stock if
at any time the authorized number of shares of Common Stock remaining unissued
shall not be sufficient to permit the conversion of all of the shares of Series
A Preferred Stock at the time outstanding.

               (g) Upon any conversion of Series A Preferred Stock pursuant to
this Section 6, the shares of Series A Preferred Stock which are converted shall
not be reissued. Upon conversion of all of the then outstanding Series A
Preferred Stock pursuant to this Section 6 and upon the taking of any action
required by law, all matters set forth in this Certificate of Designation shall
be eliminated from the Certificate of Incorporation, shares of Series A
Preferred Stock shall not be deemed outstanding for any purpose whatsoever and
all such shares shall revert to the status of authorized and unissued shares of
Preferred Stock.

               (h) Upon the occurrence of each adjustment or readjustment of the
Conversion Price for Series A Preferred Stock pursuant to this Section 6, the
Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series A Preferred Stock a certificate setting forth such adjustment
or readjustment showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the reasonable written
request at any time of any holder of Series A Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, and (ii) the number of shares of Common Stock and

          (hereinafter sometimes referred to as the "Corporation").
 
     RESOLVED, that Section 3 of the Certificate of Designation of Series A
     Preferred Stock filed on March 31, 1993 in the office of the Secretary of
     State of the State of Delaware is hereby amended to read in full as
     follows:

          Subject to the liquidation preferences of any series of Preferred
          Stock other than the Series A Preferred Stock, including, without
          limitation, any liquidation preference that provides for payments to
          any series of Preferred Stock or the Common Stock prior to or on a
          parity with any payment to holders of the Series A Preferred Stock
          provided for below (including any preferences that provide for
          additional parity or non-parity payments to the holders of the Series
          A Preferred Stock), in the event of any liquidation, dissolution or
          winding up of the Corporation, distributions to holders of Series A
          Preferred Stock and holders of Common Stock shall be made in the
          following manner:

               (a) The holders of Series A Preferred Stock shall be entitled to
          receive, prior and in preference to any distribution of any of the
          assets of the Corporation to the holders of the Common Stock by reason
          of their ownership of such stock, the amount of $1.20 per share for

          any stock split, stock combination, stock distribution or stock
          dividend with respect to such


                                                        CERTIFICATE OF AMENDMENT

          holders of Series A Preferred Stock and among the holders of any
          series of Preferred Stock ranking on a parity with the Series A
          Preferred Stock with respect to this subsection (a) of Section 3 as to
          the distribution of assets and funds upon such dissolution,
          liquidation or winding up shall be insufficient to permit the payment
          to such holders of their full liquidation payments, then the entire
          assets and funds of the Corporation legally available for such
          distribution shall be distributed ratably among such holders in
          proportion to their aggregate preferential amounts.

               (b) After payment in full to the holders of Series A Preferred
          Stock of all amounts exclusively payable on or with respect to said
          shares pursuant to subsection (a) of this Section 3, the holders of
          the Common Stock shall be entitled to receive, prior and in preference
          to any further distribution of any of the assets of the Corporation to
          its stockholders, the amount of $1.20 per share for each share of
          Common Stock then held by them, adjusted for any stock split, stock
          combination, stock distribution or stock dividend with respect to such
          shares.  If the assets and funds available for distribution among the
          holders of the Common Stock and among the holders of any series of
          Preferred Stock ranking on a parity with the Common Stock with respect
          to this subsection (b) of Section 3 as to the distribution of assets
          upon such dissolution, liquidation or winding up shall be insufficient
          to permit the payment to such holders of their full liquidation
          payments, then the entire remaining assets and funds of the
          Corporation legally available for such distribution shall be
          distributed ratably among such holders in proportion to their
          aggregate preferential amounts.

               (c) After payment in full to the holders of Common Stock of all
          amounts exclusively payable on or with respect to said shares pursuant
          to subsection (b) of this Section 3, the remaining assets of the
          Corporation, if any, shall be distributed ratably among the holders of

          dissolution, liquidation or winding up, on an "as converted" basis.
          As used in this Certificate, the term "as converted" shall mean that
          Series A Preferred Stock and all other series of Preferred Stock
          entitled to payment under this Section 3(c) shall be deemed to have
          been converted into Common Stock at the Conversion Price in effect for
          Series A Preferred Stock and the conversion prices in effect for all
          such other series of Preferred Stock, respectively, on the record date
          for such distribution.

     RESOLVED FURTHER, that Section 5 of the Certificate of Designation of
     Series A Preferred Stock filed on March 31, 1993 in the office of the

          together as a single class on an as converted basis, merge or
          consolidate with or into any other corporation or entity in any merger
          or consolidation in which the Common Stock is converted into cash or
          other consideration unless each share of Series A Preferred Stock and
          each share of such other series of Preferred Stock is converted into
          cash or other consideration equal to the greater of (1) the aggregate
          amount of such cash or other consideration payable on such shares in
          connection with a liquidation, dissolution or winding up of the
          Corporation (excluding any amount payable on a parity with the Common
          Stock on an as converted basis) or (2) the amount that would be
          payable on such shares on a liquidation, dissolution or winding up of
          the Corporation immediately prior to such merger or consolidation.

     2.   That the proposed amendment has been duly adopted in accordance with
the provisions of Section 242 of the General Corporation Law of the State of
Delaware and that notice of the taking of such action by written consent has
been given as provided in Section 228 of the General Corporation Law of the

     Visigenic Software, Inc., a Delaware corporation (the "Corporation"),
formerly known as Very Visual Software, Inc., hereby certifies that the
following resolution has been duly adopted by the Board of Directors of the
Corporation:

     RESOLVED, that pursuant to the authority expressly granted to and vested in
the Board of Directors of the Corporation (the "Board") by the provisions of the
Restated Certificate of Incorporation of the Corporation (the "Certificate of
Incorporation"), there hereby is created, out of the 4,000,000 shares of
Preferred Stock, par value $0.001 per share, of the Corporation authorized in
Article FOURTH of the Certificate of Incorporation (the "Preferred Stock"), a
series of the Preferred Stock of the Corporation consisting of 1,750,000 shares,

shall be entitled to receive dividends, out of any assets at the time legally
available therefor, when and as declared by the Board.  No cash dividends shall
be paid on any Common Stock or Series A Preferred Stock of the Corporation (the
"Series A Preferred Stock") unless at the same time a dividend is paid with

          3.  Preference on Liquidation.
              ------------------------- 

              Subject to the liquidation preferences of any series of Preferred
Stock other than the Series B Preferred Stock, including, without limitation,
any liquidation preference that provides for payments to any series of Preferred
Stock or the Common Stock prior to or on a parity with any payment to holders of
the Series B Preferred Stock provided for below (including any preferences that
provide for additional parity or non-parity payments to the holders of the
Series B Preferred Stock), in the event of any liquidation, dissolution or
winding up of the Corporation, distributions to holders of Series B Preferred
Stock, holders of Series A Preferred Stock and holders of Common Stock shall be
made in the following manner:

                  (a) The holders of Series B Preferred Stock shall be entitled
to receive, prior and in preference to any distribution of any of the assets of
the Corporation to the holders of the Common Stock by reason of their ownership
of such stock, the amount of $2.00 per share for each share of Series B
Preferred Stock then held by them, adjusted for any stock split, stock
combination, stock distribution or stock dividend with respect to such shares.
The Series B Preferred Stock shall rank on a parity with the Series A Preferred

Designation of Series A Preferred Stock filed March 31, 1993, as amended (the
"Series A Certificate"), as to the distribution of assets and funds upon
dissolution, liquidation or winding up of the Corporation, with the effect
stated in said subsection (a).

further distribution of any of the assets of the Corporation to its

held by them, adjusted for any stock split, stock combination, stock
distribution or stock dividend with respect to such shares. If the assets and
funds available for distribution among the holders of the Common Stock and among
the holders of any series of Preferred Stock ranking on a parity with the Common
Stock with respect to this subsection (b) of Section 3 as to the distribution of
assets upon such dissolution, liquidation or winding up shall be insufficient to
permit the payment to such holders of their full liquidation payments, then the
entire remaining assets and funds of the Corporation legally available for such
distribution shall be distributed ratably among such holders in proportion to
their aggregate preferential amounts.

                  (c) The Series B Preferred Stock shall rank on a parity with
the Series A Preferred Stock and the Common Stock with respect to subsection (c)
of Section 3 of the Series A Certificate, as to the distribution of remaining

dissolution, liquidation or winding up of the Corporation, with the effect
stated in said subsection (c).

          4.   Redemption.
               ---------- 

     (a) At any time and from time to time after December 17, 1994, the
Corporation may, at the option of the Board, and out of assets at the time
legally available therefor, redeem all or part (selected pro rata from among all
of the shares of Series B Preferred Stock) of the outstanding shares of Series B
Preferred Stock at the redemption price set forth in Section 4(b) below,
provided that the Corporation shall give written notice by mail, postage
prepaid, to the holders of the Series B Preferred Stock to be redeemed at least
twenty (20) days prior to the date specified for redemption (a "Redemption
Date").  The notice shall further call upon such holders to surrender to the
Corporation on or before the Redemption Date at the place designated in the
notice such holder's certificate or certificates representing the shares to be
redeemed and shall state that, in lieu of redemption, a holder may, prior to the
Redemption Date, convert its Series B Preferred Stock into Common Stock in
accordance with Section 6 below.  On or after the Redemption Date, each holder
of shares of Series B Preferred Stock called for redemption shall surrender the
certificate evidencing such shares to the Corporation, except that such number
of shares shall be reduced by the number of shares which have been converted
into Common Stock between the date of notice and the Redemption Date, at the
place designated in such notice and shall thereupon be entitled to receive
payment of the Redemption Price.

     (b)  The Series B Preferred Stock may be redeemed at a cash price equal to
$2.00 per share, adjusted for any stock split, stock combination, stock
distribution or stock dividend with respect to such shares.

     (c) From and after the Redemption Date, unless there shall have been a
default in payment of the Redemption Price, all rights of the holders with
respect to such redeemed shares of Series B Preferred Stock (except the right to
receive the Redemption Price without interest upon surrender of their
certificate) shall cease and such shares shall not thereafter be transferred on
the books of this Corporation or be deemed to be outstanding for any purpose
whatsoever.

     (d) If the funds of the Corporation legally available for redemption of
shares of Series B Preferred Stock on the Redemption Date are insufficient to
redeem the total number of shares of Series B Preferred Stock to be redeemed,
the Corporation shall use those funds which are legally available to redeem the
maximum possible number of such shares ratably among the holders of such shares
to be redeemed.  The shares of Series B Preferred Stock not redeemed shall
remain outstanding and entitled to all the rights and preferences provided
herein.

          5.   Voting.
               ------ 

     (a) Except as otherwise required by law, and except as otherwise provided
in the last sentence of Article FOURTH of the Certificate of Incorporation and

SIXTH of the Certificate of Incorporation, the shares of Series B Preferred
Stock shall be voted together with the Common Stock at any annual or special
meeting of the stockholders of the Corporation, or may act by written consent in
the same manner as the Common Stock, and shall have the voting rights and powers
equal to the voting rights of the Common Stock, upon the following basis:  each
holder of shares of Series B Preferred Stock shall be entitled to such number of
votes for the shares of Series B Preferred Stock held by him on the record date
for such meeting or action to be taken by written consent, as shall be equal to
the nearest whole number of shares of the Common Stock into which such holder's
shares of Series B Preferred Stock are convertible immediately after the close
of business on the record date for such meeting or action to be taken by written
consent, as the case may be.  Holders of Series B Preferred Stock will be
entitled to vote on such basis with holders of Common Stock in the election of
the Minority Directors pursuant to Article SIXTH of the Certificate of
Incorporation.

     (b) The Corporation shall not, without the consent of the holders of a
majority of the outstanding shares of Series B Preferred Stock and any other
series of Preferred Stock granted similar voting rights, voting together as a
single class on an as converted basis, merge or consolidate with or into any
other corporation or entity in any merger or consolidation in which the Common
Stock is converted into cash or other consideration unless each share of Series
B Preferred Stock and each share of such other series of Preferred Stock is
converted into cash or other consideration equal to the greater of (1) the
aggregate amount of such cash or other consideration payable on such shares in
connection with a liquidation, dissolution or winding up of the Corporation
(excluding any amount payable on a parity with the Common Stock on an as
converted basis) or (2) the amount that would be payable on such shares on a
liquidation, dissolution or winding up of the Corporation immediately prior to
such merger or consolidation.

          6.   Conversion Rights.  The holders of Series B Preferred Stock shall
               -----------------                                                
have conversion rights as follows:

                  (a) Each share of Series B Preferred Stock shall be
convertible, at the option of the holder thereof, at any time at the principal
office of the Corporation or any transfer agent for such shares, into fully paid
and nonassessable shares of Common Stock of the Corporation. The number of
shares of Common Stock into which each share of Series B Preferred Stock may be
converted shall be determined by dividing $2.00 by the Conversion Price
determined as hereinafter provided in effect at the time of the conversion. The
Conversion Price per share at which shares of Common Stock shall be initially
issuable upon conversion of any shares of Series B Preferred Stock shall be
$2.00, subject to adjustment as provided herein.

                  (b) Each share of Series B Preferred Stock shall be converted
into Common Stock automatically in the manner provided herein upon the earlier
to occur of (i) the time holders of a majority of the outstanding shares of all
series of Preferred Stock which are subject to conversion upon the written
consent of holders of a majority of all outstanding shares of Preferred Stock
consent in writing to the conversion of all such outstanding Preferred Stock, or
(ii) immediately prior to the closing of the sale

                                       4              CERTIFICATE OF DESIGNATION

of securities of the Corporation pursuant to a firm commitment underwritten
public offering registered with the Securities and Exchange Commission, other
than on Form S-4, or Form S-18, or any successor form thereto, with a public
offering price of not less than $3.33 per share (adjusted to reflect subsequent
stock dividends, stock splits, recapitalization and the like) and with aggregate
gross proceeds of not less than $5,000,000.

                  (c) The holder of any shares of Series B Preferred Stock may
exercise the conversion right specified in Section 6(a) by surrendering to the
Corporation or any transfer agent of the Corporation the certificate or
certificates for the shares to be converted, accompanied by written notice
specifying the number of shares to be converted. Upon the occurrence of any
event specified in Section 6(b), the outstanding shares of Series B Preferred
Stock shall be converted automatically without any further action by the holders
of such shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent; provided that the
Corporation shall not be obligated to issue to any holder certificates
evidencing the shares of Common Stock issuable upon such conversion unless
certificates evidencing such shares of Series B Preferred Stock are delivered
either to the Corporation or any transfer agent of the Corporation. Conversion
shall be deemed to have been effected on the date when delivery of notice of an
election to convert and of certificates for shares being converted is made or on
the date of the occurrence of any event specified in Section 6(b), as the case
may be, and such date is referred to herein as the "Conversion Date." As
promptly as practicable thereafter (and after surrender of the certificate or
certificates representing shares of Series B Preferred Stock to the Corporation
or any transfer agent of the Corporation in the case of conversions pursuant to
Section 6(b)) the Corporation shall issue and deliver to such holder a
certificate or certificates for the number of full shares of Common Stock to
which such holder is entitled. No fractional shares of Common Stock shall be
issued by the Corporation and all such fractional shares shall be disregarded.
In lieu thereof, the Corporation shall pay in cash the fair market value of any
such fractional share as determined by the Board. The person in whose name the
certificate or certificates for Common Stock are to be issued shall be deemed to
have become a holder of record of such Common Stock on the applicable Conversion
Date. Upon conversion of only a portion of the number of shares covered by a
certificate representing shares of Series B Preferred Stock surrendered for
conversion (in the case of conversion pursuant to Section 6(a)), the Corporation
shall issue and deliver to or upon the written order of the holder of the
certificate so surrendered for conversion, at the expense of the Corporation, a
new certificate covering the number of shares of Series B Preferred Stock
representing the unconverted portion of the certificate so surrendered.

                  (d) In case the Corporation shall at any time (i) subdivide
the outstanding Common Stock, or (ii) issue a stock dividend on its outstanding
Common Stock, the number of shares of Common Stock issuable upon conversion of
Series B Preferred Stock immediately prior to such subdivision or the issuance
of such stock dividend shall be proportionately increased by the same ratio as
the subdivision or dividend (with appropriate adjustments in the Conversion
Price of Series B Preferred Stock). In case the Corporation shall at any time
combine its outstanding Common

                                       5              CERTIFICATE OF DESIGNATION
<PAGE>
 
Stock, the number of shares of Common Stock issuable upon conversion of Series B
Preferred Stock immediately prior to such combination shall be proportionately
decreased by the same ratio as the combination (with appropriate adjustments in
the Conversion Price of Series B Preferred Stock).  All such adjustments
described herein shall be effective at the close of business on the date of such
subdivision, stock dividend or combination, as the case may be.

                  (e) In case of any merger (other than a merger in which the
Corporation is not the continuing or surviving entity) or any reclassification
of the Common Stock of the Corporation, each share of the Series B Preferred
Stock shall thereafter be convertible into that number of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock issuable upon conversion of a share of Series B Preferred Stock
immediately prior to such merger or reclassification would have been entitled
upon such merger or reclassification.  In any such case, appropriate adjustment
(as determined by the Board) shall be made in the application of the provisions
herein set forth with respect to the rights and interests thereafter of the
holders of Series B Preferred Stock, such that the provisions set forth herein
shall thereafter be applicable, as nearly as reasonably may be, in relation to
any share of stock or other property thereafter issuable upon conversion.

                  (f) The Corporation shall at all times reserve and keep
available, out of its authorized but unissued Common Stock, solely for the
purpose of effecting the conversion of Series B Preferred Stock, the full number
of shares of Common Stock deliverable upon the conversion of all Series B
Preferred Stock from time to time outstanding. The Corporation shall from time
to time (subject to obtaining necessary director and stockholder
authorizations), in accordance with the laws of the State of Delaware, increase
the authorized amount of its Common Stock if at any time the authorized number
of shares of Common Stock remaining unissued shall not be sufficient to permit
the conversion of all of the shares of Series B Preferred Stock at the time
outstanding.

                  (g) Upon any conversion of Series B Preferred Stock pursuant
to this Section 6, the shares of Series B Preferred Stock which are converted
shall not be reissued. Upon conversion of all of the then outstanding Series B
Preferred Stock pursuant to this Section 6 and upon the taking of any action
required by law, all matters set forth in this Certificate of Designation shall
be eliminated from the Certificate of Incorporation, shares of Series B
Preferred Stock shall not be deemed outstanding for any purpose whatsoever and
all such shares shall revert to the status of authorized and unissued shares of
Preferred Stock.

                  (h) Upon the occurrence of each adjustment or readjustment of
the Conversion Price for Series B Preferred Stock pursuant to this Section 6,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series B Preferred Stock a certificate setting forth such adjustment
or readjustment showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the reasonable written
request at any time of any holder of Series B

Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, and (ii) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversion of Series B Preferred Stock.
 
          (i) Any notices required by the provisions of this Section 6 to be
given to the holders of shares of Series B Preferred Stock shall be deemed given
if deposited in the United States mail, first class, postage prepaid and
addressed to each holder of record at its address appearing on the books of the
Corporation.

     IN WITNESS WHEREOF, the Corporation has caused this Certificate of
Designation to be signed by its Vice President, and attested by its Assistant
Secretary, this ______ day of December, 1993.

Board of Directors of the Corporation:

     RESOLVED, that pursuant to the authority expressly granted to and vested in
the Board of Directors of the Corporation (the "Board") by the provisions of the
Restated Certificate of Incorporation of the Corporation, as amended (the
"Certificate of Incorporation"), there hereby is created, out of the 10,000,000
shares of Preferred Stock, par value $0.001 per share, of the Corporation
authorized in Article FOURTH of the Certificate of Incorporation (the "Preferred
Stock"), a series of the Preferred Stock of the Corporation consisting of
1,000,000 shares, which series shall have the following powers, designations,
preferences and relative, participating, optional and other rights, and the
following qualifications, limitations and restrictions:

        1.     Designation and Amount.
               ---------------------- 

     This series of Preferred Stock shall be designated the Series C Preferred
Stock (the "Series C Preferred Stock"), and the authorized number of shares
constituting such series shall be 1,000,000.  The par value of the Series C
Preferred Stock shall be $0.001 per share.

        2.     Dividend Rights of Series C Preferred Stock.

Preferred Stock designated by the Board in the future, the holders of Series C
Preferred Stock shall be entitled to receive dividends, out of any assets at the
time legally available therefor, when and as declared by the Board. No cash
dividends shall be paid on any Common Stock, Series A Preferred Stock (the
"Series A Preferred Stock") or Series B Preferred Stock of the Corporation (the
"Series B Preferred Stock") unless at the same time a dividend is paid with
respect to all outstanding shares of Series C Preferred Stock in an amount for
each such share of Series C Preferred Stock equal to the aggregate amount of
such dividends payable on that number of shares of Common Stock into which each
such share of Series C Preferred Stock could then be converted.

        3.      Preference on Liquidation.

                Subject to the liquidation preferences of any series of
Preferred Stock other than the Series C Preferred Stock, including, without
limitation, any liquidation preference that provides for payments to any series
of Preferred Stock or the Common Stock prior to or on a parity with any payment
to holders of the Series C Preferred Stock provided for below (including any
preferences that provide for additional parity or non-parity payments to the
holders of the Series C Preferred Stock), in the event of any liquidation,
dissolution or winding up of the Corporation, distributions to holders of Series
C Preferred Stock, holders of Series B Preferred Stock, holders of Series A
Preferred Stock and holders of Common Stock shall be made in the following

                (a) The holders of Series C Preferred Stock shall be entitled to

Corporation to the holders of the Common Stock by reason of their ownership of
such stock, the amount of $4.50 per share for each share of Series C Preferred
Stock then held by them, adjusted for any stock split, stock combination, stock
distribution or stock dividend with respect to such shares. The Series C
Preferred Stock shall rank on a parity with the Series A Preferred Stock with
respect to subsection (a) of Section 3 of the Certificate of Designation of
Series A Preferred Stock filed March 31, 1993, as amended (the "Series A
Certificate"), as to the distribution of assets and funds upon dissolution,

                (b) After payment in full to (i) the holders of Series C
Preferred Stock of all amounts exclusively payable on or with respect to said
shares pursuant to subsection (a) of this Section 3, (ii) the holders of Series
B Preferred Stock of all amounts exclusively payable on or with respect to said

subsection (b) of Section 3 of the Series A Certificate, and (v) the holders of
Series A Preferred Stock and the holders of Common Stock of all amounts
exclusively payable on or with respect to said shares pursuant to subsection (b)
of Section 3 of the Series B Certificate, the Series C Preferred Stock shall
rank on a parity with the Series A Preferred Stock and the Common Stock with
respect to subsection (c) of Section 3 of the Series A Certificate, as to the
distribution of remaining assets upon dissolution, liquidation or winding up of
the Corporation, with the effect stated in said subsection (c).

        4.      Voting.
                ------ 

                (a) Except as otherwise required by law, and except as otherwise
provided in the last sentence of Article FOURTH of the Certificate of
Incorporation, the shares of Series C Preferred Stock shall be voted together
with the Common Stock at any annual or special meeting of the stockholders of
the Corporation, or may act by written

                                       2
<PAGE>
 
consent in the same manner as the Common Stock, and shall have the voting rights
and powers equal to the voting rights of the Common Stock, upon the following
basis:  each holder of shares of Series C Preferred Stock shall be entitled to
such number of votes for the shares of Series C Preferred Stock held by him on
the record date for such meeting or action to be taken by written consent, as
shall be equal to the nearest whole number of shares of the Common Stock into
which such holder's shares of Series C Preferred Stock are convertible
immediately after the close of business on the record date for such meeting or
action to be taken by written consent, as the case may be.  Holders of Series C
Preferred Stock will be entitled to vote on such basis with holders of Common
Stock in the election of all directors other than Preferred Directors pursuant
to Article SIXTH of the Certificate of Incorporation.

                (b)  The Corporation shall not, without the consent of the
holders of a majority of the outstanding shares of Series C Preferred Stock and
any other series of Preferred Stock granted similar voting rights, voting
together as a single class on an as converted basis, merge or consolidate with
or into any other corporation or entity in any merger or consolidation in which
the Common Stock is converted into cash or other consideration unless each share
of Series C Preferred Stock and each share of such other series of Preferred
Stock is converted into cash or other consideration equal to the greater of (1)
the aggregate amount of such cash or other consideration payable on such shares
in connection with a liquidation, dissolution or winding up of the Corporation
(excluding any amount payable on a parity with the Common Stock on an as
converted basis) or (2) the amount that would be payable on such shares on a
liquidation, dissolution or winding up of the Corporation immediately prior to
such merger or consolidation.

        5.      Conversion Rights.  The holders of Series C Preferred Stock
                -----------------                 
shall have conversion rights as follows:

                (a)  Each share of Series C Preferred Stock shall be
convertible, at the option of the holder thereof, at any time at the principal
office of the Corporation or any transfer agent for such shares, into fully paid
and nonassessable shares of Common Stock of the Corporation. The number of
shares of Common Stock into which each share of Series C Preferred Stock may be
converted shall be determined by dividing $4.50 by the Conversion Price
determined as hereinafter provided in effect at the time of the conversion. The
Conversion Price per share at which shares of Common Stock shall be initially
issuable upon conversion of any shares of Series C Preferred Stock shall be
$4.50, subject to adjustment as provided herein.

                (b)  Each share of Series C Preferred Stock shall be converted
into Common Stock automatically in the manner provided herein upon the earlier
to occur of (i) the time holders of a majority of the outstanding shares of all
series of Preferred Stock which are subject to conversion upon the written
consent of holders of a majority of all outstanding shares of Preferred Stock
consent in writing to the conversion of all such outstanding Preferred Stock, or
(ii) immediately prior to the closing of the sale of securities of the
Corporation pursuant to a firm commitment underwritten public offering
registered with the Securities and Exchange Commission, other than on 
Form S-


                                       3
<PAGE>
 
S-4, or Form S-18, or any successor form thereto, with a public offering price
of not less than $6.00 per share (adjusted to reflect subsequent stock
dividends, stock splits, recapitalization and the like) and with aggregate gross
proceeds of not less than $5,000,000.

                (c)  The holder of any shares of Series C Preferred Stock may
exercise the conversion right specified in Section 5(a) by surrendering to the
Corporation or any transfer agent of the Corporation the certificate or
certificates for the shares to be converted, accompanied by written notice
specifying the number of shares to be converted. Upon the occurrence of any
event specified in Section 5(b), the outstanding shares of Series C Preferred
Stock shall be converted automatically without any further action by the holders
of such shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent; provided that the
Corporation shall not be obligated to issue to any holder certificates
evidencing the shares of Common Stock issuable upon such conversion unless
certificates evidencing such shares of Series C Preferred Stock are delivered
either to the Corporation or any transfer agent of the Corporation. Conversion
shall be deemed to have been effected on the date when delivery of notice of an
election to convert and of certificates for shares being converted is made or on
the date of the occurrence of any event specified in Section 5(b), as the case
may be, and such date is referred to herein as the "Conversion Date." As
promptly as practicable thereafter (and after surrender of the certificate or
certificates representing shares of Series C Preferred Stock to the Corporation
or any transfer agent of the Corporation in the case of conversions pursuant to
Section 5(b)) the Corporation shall issue and deliver to such holder a
certificate or certificates for the number of full shares of Common Stock to
which such holder is entitled. No fractional shares of Common Stock shall be
issued by the Corporation and all such fractional shares shall be disregarded.
In lieu thereof, the Corporation shall pay in cash the fair market value of any
such fractional share as determined by the Board. The person in whose name the
certificate or certificates for Common Stock are to be issued shall be deemed to
have become a holder of record of such Common Stock on the applicable Conversion
Date. Upon conversion of only a portion of the number of shares covered by a
certificate representing shares of Series C Preferred Stock surrendered for
conversion (in the case of conversion pursuant to Section 5(a)), the Corporation
shall issue and deliver to or upon the written order of the holder of the
certificate so surrendered for conversion, at the expense of the Corporation, a
new certificate covering the number of shares of Series C Preferred Stock
representing the unconverted portion of the certificate so surrendered.

                (d)  In case the Corporation shall at any time (i) subdivide the
outstanding Common Stock, or (ii) issue a stock dividend on its outstanding
Common Stock, the number of shares of Common Stock issuable upon conversion of
Series C Preferred Stock immediately prior to such subdivision or the issuance
of such stock dividend shall be proportionately increased by the same ratio as
the subdivision or dividend (with appropriate adjustments in the Conversion
Price of Series C Preferred Stock). In case the Corporation shall at any time
combine its outstanding Common Stock, the number of shares of Common Stock
issuable upon conversion of Series C Preferred Stock immediately prior to such
combination shall be proportionately

                                       4
<PAGE>
 
decreased by the same ratio as the combination (with appropriate adjustments in
the Conversion Price of Series C Preferred Stock).  All such adjustments
described herein shall be effective at the close of business on the date of such
subdivision, stock dividend or combination, as the case may be.

                (e)  In case of any merger (other than a merger in which the
Corporation is not the continuing or surviving entity) or any reclassification
of the Common Stock of the Corporation, each share of the Series C Preferred
Stock shall thereafter be convertible into that number of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock issuable upon conversion of a share of Series C Preferred Stock
immediately prior to such merger or reclassification would have been entitled
upon such merger or reclassification. In any such case, appropriate adjustment
(as determined by the Board) shall be made in the application of the provisions
herein set forth with respect to the rights and interests thereafter of the
holders of Series C Preferred Stock, such that the provisions set forth herein
shall thereafter be applicable, as nearly as reasonably may be, in relation to
any share of stock or other property thereafter issuable upon conversion.

                (f)  The Corporation shall at all times reserve and keep
available, out of its authorized but unissued Common Stock, solely for the
purpose of effecting the conversion of Series C Preferred Stock, the full number
of shares of Common Stock deliverable upon the conversion of all Series C
Preferred Stock from time to time outstanding. The Corporation shall from time
to time (subject to obtaining necessary director and stockholder
authorizations), in accordance with the laws of the State of Delaware, increase
the authorized amount of its Common Stock if at any time the authorized number
of shares of Common Stock remaining unissued shall not be sufficient to permit
the conversion of all of the shares of Series C Preferred Stock at the time
outstanding.

                (g)  Upon any conversion of Series C Preferred Stock pursuant to
this Section 5, the shares of Series C Preferred Stock which are converted shall
not be reissued. Upon conversion of all of the then outstanding Series C
Preferred Stock pursuant to this Section 6 and upon the taking of any action
required by law, all matters set forth in this Certificate of Designation shall
be eliminated from the Certificate of Incorporation, shares of Series C
Preferred Stock shall not be deemed outstanding for any purpose whatsoever and
all such shares shall revert to the status of authorized and unissued shares of
Preferred Stock.

                (h)  Upon the occurrence of each adjustment or readjustment of
the Conversion Price for Series C Preferred Stock pursuant to this Section 5,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series C Preferred Stock a certificate setting forth such adjustment
or readjustment showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the reasonable written
request at any time of any holder of Series C Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, and (ii) the number of shares of Common

                                       5
<PAGE>
 
Stock and the amount, if any, of other property which at the time would be
received upon the conversion of Series C Preferred Stock.
 
                (i)  Any notices required by the provisions of this Section 5 to
be given to the holders of shares of Series C Preferred Stock shall be deemed
given if deposited in the United States mail, first class, postage prepaid and
addressed to each holder of record at its address appearing on the books of the
Corporation.

     IN WITNESS WHEREOF, the Corporation has caused this Certificate of
Designation to be signed by George H. Hohnsbeen II, its Assistant Secretary,
this ______ day of May, 1996.

               Designation"), to establish from time to time the number of
               shares to be included

               in each such series, and to fix the designation, powers,
               preferences, and rights of each such series and any
               qualifications, limitations or restrictions thereof.  The number
               of authorized shares of Preferred Stock may be increased or
               decreased (but not below the number of shares thereof then
               outstanding) by the affirmative vote of the holders of a majority
               of the Common Stock, without a vote of the holders of the
               Preferred Stock, or of any series thereof, unless a vote of any
               such holders is required pursuant to the terms of any Preferred
               Stock Designation.

     FIFTH:    The following provisions are inserted for the management of the
     -----                                                                    
               business and the conduct of the affairs of the Corporation, and
               for further definition, limitation and regulation of the powers
               of the Corporation and of its directors and stockholders:

          A.   The business and affairs of the Corporation shall be managed by
               or under the direction of the Board of Directors.  In addition to
               the powers and authority expressly conferred upon them by statute
               or by this Restated Certificate of Incorporation or the Bylaws of
               the Corporation, the directors are hereby empowered to exercise
               all such powers and do all such acts and things as may be
               exercised or done by the Corporation.

          B.   The directors of the Corporation need not be elected by written
               ballot unless the Bylaws so provide.

          C.   Any action required or permitted to be taken by the stockholders
               of the Corporation must be effected at a duly called annual or
               special meeting of stockholders of the Corporation and may not be
               effected by any consent in writing by such stockholders.

          D.   Special meetings of stockholders of the Corporation may be called
               only by either the Board of Directors pursuant to a resolution
               adopted by a majority of the total number of authorized directors
               (whether or not there exist any vacancies in previously
               authorized directorships at the time any such resolution is
               presented to the Board for adoption), the Chief Executive Officer
               or the President.

     SIXTH:
     ----- 

          A.   Subject to the rights of the holders of any series of Preferred
               Stock to elect additional directors under specified
               circumstances, the number of directors shall initially be set at
               eight (8) and, thereafter, shall be fixed from time to time
               exclusively by the Board of Directors pursuant to a resolution
               adopted by a majority

                                                
                                        2
<PAGE>
 
               of the total number of authorized directors (whether or not there
               exist any vacancies in previously authorized directorships at the
               time any such resolution is presented to the Board for adoption).
               The directors, other than those who may be elected by the holders
               of Preferred Stock under specified circumstances, shall be
               divided into three classes with the term of office of the first
               class (Class I) to expire at the annual meeting of the
               stockholders held in 1997; the term of office of the second class
               (Class II) to expire at the annual meeting of stockholders held
               in 1998; the term of office of the third class (Class III) to
               expire at the annual meeting of stockholders held in 1999; and
               thereafter for each such term to expire at each third succeeding
               annual meeting of stockholders after such election.  All
               directors shall hold office until the expiration of the term for
               which elected, and until their respective successors are elected,
               except in the case of the death, resignation, or removal of any
               director.

          B.   Subject to the rights of the holders of any series of Preferred
               Stock then outstanding, newly created directorships resulting
               from any increase in the authorized number of directors or any
               vacancies in the Board of Directors resulting from death,
               resignation or other cause may be filled only by a majority vote
               of the directors then in office, though less than a quorum, and
               directors so chosen shall hold office for a term expiring at the
               next annual meeting of stockholders at which the term of office
               of the class to which they have been elected expires, and until
               their respective successors are elected, except in the case of
               the death, resignation, or removal of any director. No decrease
               in the number of directors constituting the Board of Directors
               shall shorten the term of any incumbent director.

          C.   Subject to the rights of the holders of any series of Preferred
               Stock then outstanding, any directors, or the entire Board of
               Directors, may be removed from office at any time, but only for
               cause and only by the affirmative vote of the holders of at least
               sixty-six and two-thirds percent (66-2/3%) of the voting power of
               all of the then outstanding shares of capital stock of the
               Corporation entitled to vote generally in the election of
               directors, voting together as a single class.

     SEVENTH:  The Board of Directors is expressly empowered to adopt, amend or
     -------                                                                   
               repeal Bylaws of the Corporation.  Any adoption, amendment or
               repeal of Bylaws of the Corporation by the Board of Directors
               shall require the approval of a majority of the total number of
               authorized directors (whether or not there exist any vacancies in
               previously authorized directorships at the time any resolution

                                       3
<PAGE>
 
               providing for adoption, amendment or repeal is presented to the
               Board).  The stockholders shall also have power to adopt, amend
               or repeal the Bylaws of the Corporation.  Any adoption, amendment
               or repeal of Bylaws of the Corporation by the stockholders shall
               require, in addition to any vote of the holders of any class or
               series of stock of the Corporation required by law or by this
               Restated Certificate of Incorporation, the affirmative vote of
               the holders of at least sixty-six and two-thirds percent 
               (66-2/3%) of the voting power of all of the then outstanding 
               shares of the capital stock of the Corporation entitled to vote
               generally in the election of directors, voting together as a
               single class.

     EIGHTH:   A director of the Corporation shall not be personally liable to
     ------                                                                   
               the Corporation or its stockholders for monetary damages for
               breach of fiduciary duty as a director, except for liability
               (i) for any breach of the director's duty of loyalty to the
               Corporation or its stockholders, (ii) for acts or omissions not
               in good faith or which involved intentional misconduct or a
               knowing violation of law, (iii) under Section 174 of the Delaware
               General Corporation Law, or (iv) for any transaction from which
               the director derived an improper personal benefit.

               If the Delaware General Corporation Law is hereafter amended to
               authorize the further elimination or limitation of the liability
               of a director, then the liability of a director of the
               Corporation shall be eliminated or limited to the fullest extent
               permitted by the Delaware General Corporation Law, as so amended.

               Any repeal or modification of the foregoing provisions of this
               Article EIGHTH by the stockholders of the Corporation shall not
               adversely affect any right or protection of a director of the
               Corporation existing at the time of such repeal or modification.

     NINTH:    The Corporation reserves the right to amend or repeal any
     -----                                                              
               provision contained in this Restated Certificate of Incorporation
               in the manner prescribed by the laws of the State of Delaware and
               all rights conferred upon stockholders are granted subject to
               this reservation; provided, however, that, notwithstanding any
                                 --------  -------                           
               other provision of this Restated Certificate of Incorporation or
               any provision of law which might otherwise permit a lesser vote
               or no vote, but in addition to any vote of the holders of any
               class or series of the stock of this Corporation required by law
               or by this Restated Certificate of Incorporation, the affirmative
               vote of the holders of at least sixty-six and two-thirds percent
               (66-2/3%) of the voting power of all of the then outstanding
               shares of the capital stock of the Corporation entitled to vote
               generally in the

     -----------  ------------------------------                          
meeting of the stockholders, only such business shall be conducted as shall have

in writing to the Secretary of the Corporation.  To be timely, a stockholder
proposal to be presented at an annual meeting shall be received at the
Corporation's principal executive offices not less than 120 calendar days in

year's proxy statement, or in the event of a special meeting, notice by the
stockholder to be timely must be received not later than the close of business
on the tenth day following the day on which such notice of the date of the
meeting was mailed or such public disclosure was made.  A stockholder's notice

bring before the annual or special meeting (a) a brief description of the
business desired to be brought before the annual or special meeting and the
reasons for conducting such business at the special meeting, (b) the name and

stockholder entitled to vote may vote in person or by proxy authorized by an
instrument in writing or by a transmission permitted by law filed in accordance
with the procedure established for the meeting.  No stockholder may authorize
more than one proxy for his shares.

vote which is registered in his or her name on the record date for the meeting,
except as otherwise provided herein or required by law.

     All voting, including on the election of directors but excepting where
otherwise required by law, may be by a voice vote; provided, however, that upon
demand therefor by a stockholder entitled to vote or his or her proxy, a stock
vote shall be taken.  Every stock vote shall be taken by ballots, each of which
shall state the name of the stockholder or proxy voting and such other
information as may be required under the procedure established for the meeting.
Every vote taken by ballots shall be counted by an inspector or inspectors
appointed by the chairman of the meeting.

Directors, may be removed from office at any time, with or without cause, but
only by the affirmative vote of the holders of at least 66-2/3% of the voting
power of all of the then outstanding shares of capital stock of the Corporation
entitled to vote generally in the election of directors, voting together as a
single class.  Vacancies in the Board of Directors resulting from such removal

quorum.  Directors so chosen shall hold office until the next annual meeting of
stockholders.

nearest whole number), by the Chairman of the Board, or by the chief executive

committee appointed by the Board of Directors or by any stockholder entitled to
vote in the election of Directors generally.  However, any stockholder entitled
to vote in the election of Directors generally may nominate one or more persons
for election as Directors at a meeting only if timely notice of such
stockholder's intent to make such nomination or nominations has been given in
writing to the Secretary of the Corporation.  To be timely, a  stockholder
nomination for a director to be elected at an annual meeting shall be received
at the Corporation's principal executive offices not less than 120 calendar days

contemplated at the time of the previous year's proxy statement, or in the event
of a nomination for director to be elected at a  special meeting, notice by the
stockholders to be timely must be received not later than the close of business
on the tenth day following the day on which such notice of the date of the
special meeting was mailed or such public disclosure was made.  Each such notice
shall set forth:  (a) the name and address of the stockholder who intends to
make the nomination and of the person or persons to be nominated; (b) a
representation that the stockholder is a holder of record of stock of the
Corporation entitled to vote for the election of Directors on the date of such

the person or persons specified in the notice; (c) a description of all
arrangements or understandings between the stockholder and each nominee and any
other person or persons (naming such person or persons) pursuant to which the
nomination or nominations are to be made by the stockholder; (d) such other

required to be included in a proxy statement filed pursuant to the proxy rules
of the Securities and Exchange Commission, had the nominee been nominated, or

nominee to serve as a director of the Corporation if so elected.

     In the event that a person is validly designated as a nominee in accordance
with this Section 2.11 and shall thereafter become unable or unwilling to stand
for election to the Board of Directors, the Board of Directors or the
stockholder who proposed such nominee, as the case may be, may designate a
substitute nominee upon delivery, not fewer than five days prior to the date of
the meeting for the election of such nominee, of a written notice to the
Secretary setting forth such information regarding such substitute nominee as
would have been required to be delivered to the Secretary pursuant to this
Section 2.11 had such substitute nominee been initially proposed as a nominee.
Such notice shall include a signed consent to serve as a director of the
Corporation, if elected, of each such substitute nominee.

     If the chairman of the meeting for the election of Directors determines
that a nomination of any candidate for election as a Director at such meeting
was not made in accordance with the applicable provisions of this Section 2.11,
such nomination shall be void.

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

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS
                   -----------------------------------------

     Section 8.1  Right to Indemnification.  Each person who was or is made a
     -----------  ------------------------                                   
party or is threatened to be made a party to or is involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative
("proceeding"), by reason of the fact that he or she or a person of whom he or
she is the legal representative, is or was a director or officer of the
Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, or of a
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a director, officer, employee or agent
in any other capacity while serving as a director, officer, employee or agent
shall be indemnified and held harmless by the Corporation to the fullest extent
authorized by Delaware Law, as the same exists or may hereafter be amended (but,
in the case of any such amendment, only to the extent that such amendment
permits the Corporation to provide broader indemnification rights than said Law
permitted the Corporation to provide prior to such amendment) against all
expenses, liability and loss (including attorneys' fees, judgments, fines, ERISA
excise taxes or penalties, amounts paid or to be paid in settlement and amounts
expended in seeking indemnification granted to such person under applicable law,
this bylaw or any agreement with the Corporation) reasonably incurred or
suffered by such person in connection therewith and such indemnification shall
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of his or her heirs, executors and
administrators; provided, however, that, except as provided in Section 8.2 of
                --------  -------                                            
this Article VIII, the Corporation shall indemnify any such person seeking
indemnity in connection with an action, suit or proceeding (or part thereof)
initiated by such person only if (a) such indemnification is expressly required
to be made by law, (b) the action, suit or proceeding (or part thereof) was
authorized by the Board of Directors of the Corporation, (c) such
indemnification is provided by the Corporation, in its sole discretion, pursuant
to the powers vested in the Corporation under the Delaware General Corporation
Law, or (d) the action, suit or proceeding (or part thereof) is brought to
establish or enforce a right to indemnification under an indemnity agreement or
any other statute or law or otherwise as required under Section 145 of the
Delaware General Corporation Law.  Such right shall be a contract right and
shall include the right to be paid by the Corporation expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
                                                                   -------- 
however, that, unless the Delaware General Corporation Law then so prohibits,
- -------                                                                      
the payment of such expenses incurred by a director or officer of the
Corporation in his or her capacity as a director or officer (and not in any
other capacity in which service was or is rendered by such person while a
director or officer, including, without limitation, service to an

                                      12
<PAGE>
 
employee benefit plan) in advance of the final disposition of such proceeding,
shall be made only upon delivery to the Corporation of an undertaking, by or on
behalf of such director or officer, to repay all amounts so advanced if it
should be determined ultimately that such director or officer is not entitled to
be indemnified under this Section or otherwise.

     Section 8.2  Right of Claimant to Bring Suit.  If a claim under Section 1
     -----------  -------------------------------                             
of this Article VIII is not paid in full by the Corporation within ninety (90)
days after a written claim has been received by the Corporation, the claimant
may at any time thereafter bring suit against the Corporation to recover the
unpaid amount of the claim and, if such suit is not frivolous or brought in bad
faith, the claimant shall be entitled to be paid also the expense of prosecuting
such claim.  The burden of proving such claim shall be on the claimant.  It
shall be a defense to any such action (other than an action brought to enforce a
claim for expenses incurred in defending any proceeding in advance of its final
disposition where the required undertaking, if any, has been tendered to this
Corporation) that the claimant has not met the standards of conduct which make
it permissible under the Delaware General Corporation Law for the Corporation to
indemnify the claimant for the amount claimed.  Neither the failure of the
Corporation (including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
Delaware General Corporation Law, nor an actual determination by the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) that the claimant has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that claimant has not
met the applicable standard of conduct.

     Section 8.3  Indemnification of Employees and Agents.  The Corporation may,
     -----------  ---------------------------------------                       
to the extent authorized from time to time by the Board of Directors, grant
rights to indemnification, and to the advancement of related expenses, to any
employee or agent of the Corporation to the fullest extent of the provisions of
this Article with respect to the indemnification of and advancement of expenses
to directors and officers of the Corporation.

     Section 8.4  Non-Exclusivity of Rights.  The rights conferred on any person
     -----------  -------------------------                                     
in Sections 1 and 2 shall not be exclusive of any other right which such persons
may have or hereafter acquire under any statute, provision of the Certificate of
Incorporation, bylaw, agreement, vote of stockholders or disinterested directors
or otherwise.

     Section 8.5  Indemnification Contracts.  The Board of Directors is
     -----------  -------------------------                            
authorized to enter into a contract with any director, officer, employee or
agent of the Corporation, or any person serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, including employee
benefit plans, providing for indemnification rights equivalent to or, if the
Board of Directors so determines, greater than, those provided for in this
Article VIII.

     Section 8.6  Insurance.  The Corporation may maintain insurance, at its
     -----------  ---------                                                 
expense, to protect itself and any such director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise against any such expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

     Section 8.7  Effect of Amendment.  Any amendment, repeal or modification of
     -----------  -------------------                                           
any provision of this Article VIII by the stockholders or the directors of the
Corporation shall not adversely affect any right or protection of a director or
officer of the Corporation existing at the time of such amendment, repeal or
modification.

                                   ARTICLE IX
                                   ----------

                                   AMENDMENTS
                                   ----------

     Section 9.1  Amendment of Bylaws.  The Board of Directors is expressly
     -----------  -------------------                                      
empowered to adopt, amend or repeal Bylaws of the Corporation.  Any adoption,
amendment or repeal of Bylaws of the Corporation by the Board of Directors shall
require the approval of a majority of the total number of authorized directors
(whether or not there exist any vacancies in previously authorized directorships
at the time any resolution providing for adoption, amendment or repeal is
presented to the Board).  The stockholders shall also have power to adopt, amend
or repeal the Bylaws of the Corporation.  Any adoption, amendment or repeal of
By-Laws of the Corporation by the stockholders shall require, in addition to any
vote of the holders of any class or series of stock of the Corporation required
by law or by the Certificate of Incorporation, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting
power of all of the then outstanding shares of the capital stock of the
Corporation entitled to vote generally in the election of directors, voting
together as a single class.

                              INDEMNITY AGREEMENT


     This Indemnity Agreement, dated as of ____________________________, 1996 is
made by and between Visigenic Software, Inc., a Delaware corporation (the
"Company"), and _____________________________________________ (the
"Indemnitee").


                                    RECITALS
                                    --------

     A.  The Company is aware that competent and experienced persons are
reluctant to serve as directors, officers or agents of corporations unless they
are protected by comprehensive liability insurance or indemnification, due to
exposure to litigation costs and risks resulting from their service to such
corporations, and due to the fact that the exposure frequently bears no
reasonable relationship to the compensation of such directors, officers and
other agents.

     B.  The statutes and judicial decisions regarding the duties of directors
and officers are often difficult to apply, ambiguous, or conflicting, and
therefore fail to provide such directors, officers and agents with adequate,
reliable knowledge of legal risks to which they are exposed or information
regarding the proper course of action to take.

     C.  Plaintiffs often seek damages in such large amounts and the costs of
litigation may be so enormous (whether or not the case is meritorious), that the
defense and/or settlement of such litigation is often beyond the personal
resources of directors, officers and other agents.

     D.  The Company believes that it is unfair for its directors, officers and
agents and the directors, officers and agents of its subsidiaries to assume the
risk of huge judgments and other expenses which may occur in cases in which the
director, officer or agent received no personal profit and in cases where the
director, officer or agent was not culpable.

     E.  The Company recognizes that the issues in controversy in litigation
against a director, officer or agent of a corporation such as the Company or its
subsidiaries are often related to the knowledge, motives and intent of such
director, officer or agent, that he is usually the only witness with knowledge
of the essential facts and exculpating circumstances regarding such matters, and
that the long period of time which usually elapses before the trial or other
disposition of such litigation often extends beyond the time that the director,
officer or agent can reasonably recall such matters; and may extend beyond the
normal time for retirement for such director, officer or agent with the result
that he, after retirement or in the event of his death, his spouse, heirs,
executors or administrators, may be faced with limited ability and undue
hardship in maintaining an adequate defense, which may discourage such a
director, officer or agent from serving in that position.

     F.  Based upon their experience as business managers, the Board of
Directors of the Company (the "Board") has concluded that, to retain and attract
talented and experienced individuals to serve as directors, officers and agents
of the Company and its subsidiaries and to encourage such individuals to take
the business risks necessary for the success of the Company and its
subsidiaries, it is necessary for the Company to contractually indemnify its
directors, officers and agents and the directors, officers and agents of its
subsidiaries, and to assume for itself maximum liability for expenses and
damages in connection with claims against such directors, officers and agents in
connection with their service to the Company and its subsidiaries, and has
further concluded that the failure to provide such contractual indemnification
could result in great harm to the Company and its subsidiaries and the Company's
stockholders.
<PAGE>
 
     G.  Section 145 of the General Corporation Law of Delaware, under which the
Company is organized ("Section 145"), empowers the Company to indemnify its
directors, officers, employees and agents by agreement and to indemnify persons
who serve, at the request of the Company, as the directors, officers, employees
or agents of other corporations or enterprises, and expressly provides that the
indemnification provided by Section 145 is not exclusive.

     H.  The Company desires and has requested the Indemnitee to serve or
continue to serve as a director, officer or agent of the Company and/or one or
more subsidiaries of the Company free from undue concern for claims for damages
arising out of or related to such services to the Company and/or one or more
subsidiaries of the Company.

     I.  Indemnitee is willing to serve, or to continue to serve, the Company
and/or one or more subsidiaries of the Company, provided that he is furnished
the indemnity provided for herein.

                                   AGREEMENT
                                   ---------

     NOW, THEREFORE, the parties hereto, intending to be legally bound, hereby
agree as follows:

     1.   Definitions.
          ----------- 

          (a) Agent.  For the purposes of this Agreement, "agent" of the Company
              -----                                                             
means any person who is or was a director, officer, employee or other agent of
the Company or a subsidiary of the Company; or is or was serving at the request
of, for the convenience of, or to represent the interests of the Company or a
subsidiary of the Company as a director, officer, employee or agent of another
foreign or domestic corporation, partnership, joint venture, trust or other
enterprise; or was a director, officer, employee or agent of another enterprise
at the request of, for the convenience of, or to represent the interests of such
predecessor corporation.

          (b) Expenses.  For purposes of this Agreement, "expenses" include all
              --------                                                         
direct and indirect costs of any type or nature whatsoever (including, without
limitation, all attorneys' fees and related disbursements, other out-of-pocket
costs actually and reasonably incurred by the Indemnitee in connection with
either the investigation, defense or appeal of a proceeding or establishing or
enforcing a right to indemnification under this Agreement or Section 145 or
otherwise); provided, however, that "expenses" shall not include any judgments,
fines, ERISA excise taxes or penalties, or amounts paid in settlement of a
proceeding.

          (c) Proceeding.  For the purposes of this Agreement, "proceeding"
              ----------                                                   
means any threatened, pending, or completed action, suit or other proceeding,
whether civil, criminal, administrative, or investigative.

          (d) Subsidiary.  For purposes of this Agreement, "subsidiary" means
              ----------                                                     
any corporation of which more than 50% of the outstanding voting securities is
owned directly or indirectly by the Company, by the Company and one or more
other subsidiaries, or by one or more other subsidiaries.

     2.  Agreement to Serve.  The Indemnitee agrees to serve and/or continue to
         ------------------                                                    
serve as agent of the Company, at its will (or under separate agreement, if such
agreement exists), in the capacity Indemnitee currently serves as an agent of
the Company, so long as he is duly appointed or elected and qualified in
accordance with the applicable provisions of the Bylaws of the Company or

                                       2
<PAGE>
 
any subsidiary of the Company or until such time as he tenders his resignation
in writing; provided, however, that nothing contained in this Agreement is
intended to create any right to continued employment by Indemnitee.

     3.   Liability Insurance.
          ------------------- 

          (a) Maintenance of D&O Insurance.  The Company hereby covenants and
              ----------------------------                                   
agrees that, so long as the Indemnitee shall continue to serve as an agent of
the Company and thereafter so long as the Indemnitee shall be subject to any
possible proceeding by reason of the fact that the Indemnitee was an agent of
the Company, the Company, subject to Section 3(c), shall promptly obtain and
maintain in full force and effect directors' and officers' liability insurance
("D&O Insurance") in reasonable amounts from established and reputable insurers.

          (b) Rights and Benefits.  In all policies of D&O Insurance, the
              -------------------                                        
Indemnitee shall be named as an insured in such a manner as to provide the
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's directors, if the Indemnitee is a director; or of the
Company's officers, if the Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, if the Indemnitee is not a director
or officer but is a key employee.

          (c) Limitation on Required Maintenance of D&O Insurance.
              ---------------------------------------------------  
Notwithstanding the foregoing, the Company shall have no obligation to obtain or
maintain D&O Insurance if the Company determines in good faith that such
insurance is not reasonably available, the premium costs for such insurance are
disproportionate to the amount of coverage provided, the coverage provided by
such insurance is limited by exclusions so as to provide an insufficient
benefit, or the Indemnitee is covered by similar insurance maintained by a
subsidiary of the Company.

     4.   Mandatory Indemnification.  Subject to Section 9 below, the Company
          -------------------------                                          
shall indemnify the Indemnitee as follows:

          (a) Successful Defense.  To the extent the Indemnitee has been
              ------------------                                        
successful on the merits or otherwise in defense of any proceeding (including,
without limitation, an action by or in the right of the Company) to which the
Indemnitee was a party by reason of the fact that he is or was an Agent of the
Company at any time, against all expenses of any type whatsoever actually and
reasonably incurred by him in connection with the investigation, defense or
appeal of such proceeding.

          (b) Third Party Actions.  If the Indemnitee is a person who was or is
              -------------------                                              
a party or is threatened to be made a party to any proceeding (other than an
action by or in the right of the Company) by reason of the fact that he is or
was an agent of the Company, or by reason of anything done or not done by him in
any such capacity, the Company shall indemnify the Indemnitee against any and
all expenses and liabilities of any type whatsoever (including, but not limited
to, judgments, fines, ERISA excise taxes and penalties, and amounts paid in
settlement) actually and reasonably incurred by him in connection with the
investigation, defense, settlement or appeal of such proceeding, provided the
Indemnitee acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company and its stockholders, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful.

          (c) Derivative Actions.  If the Indemnitee is a person who was or is a
              ------------------                                                
party or is threatened to be made a party to any proceeding by reason of the
fact that he is or was an agent of the Company, or by reason of anything done or
not done by him in any such capacity, the Company shall indemnify the Indemnitee
against any amounts paid in settlement of any such proceeding and all


                                       3
<PAGE>
 
expenses actually and reasonably incurred by him in connection with the
investigation, defense, settlement, or appeal of such proceeding, provided the
Indemnitee acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company and its stockholders.  The
Company shall indemnify the Indemnitee against judgments, fines, and ERISA
excise taxes and penalties to the same extent and subject to the same conditions
as described in the immediately preceding sentence.  Notwithstanding the
foregoing, no indemnification under this subsection 4(c) shall be made in
respect to any claim, issue or matter as to which such person shall have been
finally adjudged to be liable to the Company by a court of competent
jurisdiction unless and only to the extent that the court in which such
proceeding was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such amounts which the
court shall deem proper.

          (d) Actions where Indemnitee is Deceased.  If the Indemnitee is a
              ------------------------------------                         
person who was or is a party or is threatened to be made a party to any
proceeding by reason of the fact that he is or was an agent of the Company, or
by reason of anything done or not done by him in any such capacity, and if prior
to, during the pendency of after completion of such proceeding Indemnitee
becomes deceased, the Company shall indemnify the Indemnitee's heirs, executors
and administrators against any and all expenses and liabilities of any type
whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes
and penalties, and amounts paid in settlement) actually and reasonably incurred
to the extent Indemnitee would have been entitled to indemnification pursuant to
Sections 4(a), 4(b), or 4(c) above were Indemnitee still alive.

          (e) Notwithstanding the foregoing, the Company shall not be obligated
to indemnify the Indemnitee for expenses or liabilities of any type whatsoever
(including, but not limited to, judgments, fines, ERISA excise taxes and
penalties, and amounts paid in settlement) for which payment is actually made to
Indemnitee under a valid and collectible insurance policy of D&O Insurance, or
under a valid and enforceable indemnity clause, by-law or agreement.

     5.  Partial Indemnification.  If the Indemnitee is entitled under any
         -----------------------                                          
provision of this Agreement to indemnification by the Company for some or a
portion of any expenses or liabilities of any type whatsoever (including, but
not limited to, judgments, fines, ERISA excise taxes and penalties, and amounts
paid in settlement) incurred by him in the investigation, defense, settlement or
appeal of a proceeding, but not entitled, however, to indemnification for all of
the total amount hereof, the Company shall nevertheless indemnify the Indemnitee
for such total amount except as to the portion hereof to which the Indemnitee is
not entitled.

     6.  Mandatory Advancement of Expenses.  Subject to Section 8(a) below, the
         ---------------------------------                                     
Company shall advance all expenses incurred by the Indemnitee in connection with
the investigation, defense, settlement or appeal of any proceeding to which the
Indemnitee is a party or is threatened to be made a party by reason of the fact
that the Indemnitee is or was an agent of the Company.  Indemnitee hereby
undertakes to repay such amounts advanced only if, and to the extent that, it
shall be determined ultimately that the Indemnitee is not entitled to be
indemnified by the Company as authorized hereby.  The advances to be made
hereunder shall be paid by the Company to the Indemnitee within twenty (20) days
following delivery of a written request therefor by the Indemnitee to the
Company.


                                       4
<PAGE>
 
     7.   Notice and Other Indemnification Procedures.
          ------------------------------------------- 

          (a) Promptly after receipt by the Indemnitee of notice of the
commencement of or the threat of commencement of any proceeding, the Indemnitee
shall, if the Indemnitee believes that indemnification with respect thereto may
be sought from the Company under this Agreement, notify the Company of the
commencement or threat of commencement thereof.

          (b) If, at the time of the receipt of a notice of the commencement of
a proceeding pursuant to Section 7(a) hereof, the Company has D&O Insurance in
effect, the Company shall give prompt notice of the commencement of such
proceeding to the insurers in accordance with the procedures set forth in the
respective policies.  The Company shall thereafter take all necessary or
desirable action to cause such insurers to pay, on behalf of the Indemnitee, all
amounts payable as a result of such proceeding in accordance with the terms of
such policies.

          (c) In the event the Company shall be obligated to pay the expenses of
any proceeding against the Indemnitee, the Company, if appropriate, shall be
entitled to assume the defense of such proceeding, with counsel approved by the
Indemnitee, upon the delivery to the Indemnitee of written notice of its
election so to do.  After delivery of such notice, approval of such counsel by
the Indemnitee and the retention of such counsel by the Company, the Company
will not be liable to the Indemnitee under this Agreement for any fees of
counsel subsequently incurred by the Indemnitee with respect to the same
proceeding, provided that (i) the Indemnitee shall have the right to employ his
counsel in any such proceeding at the Indemnitee's expense; and (ii) if (A) the
employment of counsel by the Indemnitee has been previously authorized by the
Company, (B) the Indemnitee shall have reasonably concluded that there may be a
conflict of interest between the Company and the Indemnitee in the conduct of
any such defense, or (C) the Company shall not, in fact, have employed counsel
to assume the defense of such proceeding, then the fees and expenses of
Indemnitee's counsel shall be at the expense of the Company.

     8.   Exceptions.  Any other provision herein to the contrary
          ----------                                             
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

          (a) Claims Initiated by Indemnitee.  To indemnify or advance expenses
              ------------------------------                                   
to the Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by the Indemnitee and not by way of defense, unless (i) such
indemnification is expressly required to be made by law, (ii) the proceeding was
authorized by the Board, (iii) such indemnification is provided by the Company,
in its sole discretion, pursuant to the powers vested in the Company under the
General Corporation Law of Delaware or (iv) the proceeding is brought to
establish or enforce a right to indemnification under this Agreement or any
other statute or law or otherwise as required under Section 145.

          (b) Lack of Good Faith.  To indemnify the Indemnitee for any expenses
              ------------------                                               
incurred by the Indemnitee with respect to any proceeding instituted by the
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that the proceeding was not brought by the Indemnitee in
good faith or was frivolous; or

          (c) Unauthorized Settlements.  To indemnify the Indemnitee under this
              ------------------------                                         
Agreement for any amounts paid in settlement of a proceeding unless the Company
consents to such settlement, which consent shall not be unreasonably withheld.


                                       5
<PAGE>
 
     9.   Non-exclusivity.  The provisions for indemnification and advancement
          --------------
          of-expenses set forth in this Agreement shall not be deemed exclusive
          of any other rights which the Indemnitee may have under any provision
          of law, the Company's Certificate of Incorporation or Bylaws, the vote
          of the Company's stockholders or disinterested directors, other
          agreements, or otherwise, both as to action in his official capacity
          and to action in another capacity while occupying his position as an
          agent of the Company, and the Indemnitee's rights hereunder shall
          continue after the Indemnitee has ceased acting as an agent of the
          Company and shall inure to the benefit of the heirs, executors and
          administrators of the Indemnitee.


     10.  Enforcement.  Any right to indemnification or advances granted by
          -----------                                 
this Agreement to Indemnitee shall be enforceable by or on behalf of Indemnitee
in any court of competent jurisdiction if (i) the claim for indemnification or
advances is denied, in whole or in part, or (ii) no disposition of such claim is
made within ninety (90) days of request therefor. Indemnitee, in such
enforcement action, if successful in whole or in part, shall be entitled to be
paid also the expense of prosecuting his claim. It shall be a defense to any
action for which a claim for indemnification is made under this Agreement (other
than an action brought to enforce a claim for expenses pursuant to Section 6
hereof, provided that the required undertaking has been tendered to the Company)
that Indemnitee is not entitled to indemnification because of the limitations
set forth in Sections 4 and 8 hereof. Neither the failure of the Corporation
(including its Board of Directors or its stockholders) to have made a
determination prior to the commencement of such enforcement action that
indemnification of Indemnitee is proper in the circumstances, nor an actual
determination by the Company (including its Board of Directors or its
stockholders) that such indemnification is improper, shall be a defense to the
action or create a presumption that Indemnitee is not entitled to

     1.   ESTABLISHMENT, PURPOSE AND TERM OF PLAN.
          --------------------------------------- 

          1.1  ESTABLISHMENT. The Visigenic Software, Inc. 1996 Employee Stock

of the Participating Company Group with an opportunity to acquire a proprietary
interest in the Company through the purchase of Stock. The Company intends that
the Plan shall qualify as an "employee stock purchase plan" under Section 423 of
the Code (including any amendments or replacements of such section), and the
Plan shall be so construed.

          1.3  TERM OF PLAN. The Plan shall continue in effect until the earlier
of its termination by the Board or the date on which all of the shares of Stock
available for issuance under the Plan have been issued.

     2.   DEFINITIONS AND CONSTRUCTION.
          ---------------------------- 

          2.1  DEFINITIONS. Any term not expressly defined in the Plan but
defined for purposes of Section 423 of the Code shall have the same definition
herein. Whenever used herein, the following terms shall have their respective
meanings set forth below:

               (a) "BOARD" means the Board of Directors of the Company. If one

Unless the powers of the Committee have been specifically limited, the Committee
shall have all of the powers of the Board granted herein, including, without

Plan, a Participant's base salary, bonuses, and commissions paid in cash during

reimbursements of expenses, allowances, long-term disability, workers'

amended.

          (i) "FAIR MARKET VALUE" means, as of any date, if there is then a

Automated Quotation ("NASDAQ") System, the NASDAQ National Market System or such
other national or regional securities exchange or market system constituting the
primary market for the Stock.  If the relevant date does not fall on a day on
which the Stock is trading on NASDAQ, the NASDAQ National Market System or other
national or regional securities exchange or market system, the date on which the
Fair Market Value shall be established shall be the last day on which the Stock

determined by the Board without regard to any restriction other than a
restriction which, by its terms, will never lapse.  Notwithstanding the
foregoing, the Fair Market Value per share of Stock on the Effective Date shall
be deemed to be the public offering price set forth in the final prospectus

     3.  ADMINISTRATION.  The Plan shall be administered by the Board, including
         --------------                                                         
any duly appointed Committee of the Board.  All questions of interpretation of
the Plan or of any Purchase Right shall be determined by the Board and shall be
final and binding upon all persons having an interest in the Plan or the
Purchase Right.  Subject to the provisions of the Plan, the Board shall
determine all of the relevant terms and conditions of Purchase Rights granted
pursuant to the Plan; provided, however, that all Participants granted Purchase
Rights pursuant to the Plan shall have the same rights and privileges within the
meaning of Section 423(b)(5) of the Code.  All expenses incurred in connection
with the administration of the Plan shall be paid by the Company.

     4.  SHARES SUBJECT TO PLAN.
         ---------------------- 

         4.1  MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to adjustment as

may be issued under the Plan shall be four hundred fifty thousand (450,000) and
shall consist of authorized but unissued or reacquired shares of the Stock, or
any combination thereof. If an outstanding Purchase Right for any reason expires

portion of such Purchase Right shall again be available for issuance under the
Plan.

         4.2  ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital structure of the Company, or
in the event of any merger (including a merger effected for the purpose of
changing the Company's domicile), sale of assets or other reorganization in
which the Company is a party, appropriate adjustments shall be made in the
number and class of shares subject to the Plan, the Per Offering Share Limit set
forth in Section 8.1 and each Purchase Right and in the Purchase Price.

     5.  ELIGIBILITY.
         ----------- 

         5.1  EMPLOYEES ELIGIBLE TO PARTICIPATE. Any Employee of a Participating
Company is eligible to participate in the Plan except the following:

              (a) Employees who are customarily employed by the Participating
Company Group for twenty (20) hours or less per week;

              (b) Employees who are customarily employed by the Participating
Company Group for not more than five (5) months in any calendar year; and

              (c) Employees who own or hold options to purchase or who, as a
result of participation in the Plan, would own or hold options to purchase,
stock of the Company or of any Parent Corporation or Subsidiary Corporation
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of such corporation within the meaning of Section

<PAGE>
 
          5.2 LEASED EMPLOYEES EXCLUDED. Notwithstanding anything herein to the
contrary, any individual performing services for a Participating Company solely
through a leasing agency or employment agency shall not be deemed an "Employee"
of such Participating Company.

     6.   OFFERINGS.
          --------- 

          6.1  OFFERING PERIODS. Except as otherwise set forth below, the Plan
shall be implemented by sequential Offerings of approximately six (6) months
duration (an "OFFERING PERIOD"); provided, however that the first Offering
Period shall commence on the Effective Date and end on January 31, 1997 (the
"INITIAL OFFERING PERIOD"). Subsequent Offerings shall commence on the first
days of February and August of each year and end on the last days of the next
July and January, respectively, occurring thereafter. Notwithstanding the
foregoing, the Board may establish a different term for one or more Offerings or
different commencing or ending dates for such Offerings; provided, however, that
no Offering may exceed a term of twenty-seven (27) months. An Employee who
becomes an Eligible Employee after an Offering Period has commenced shall not be
eligible to participate in such Offering but may participate in any subsequent
Offering provided such Employee is still an Eligible Employee as of the
commencement of any such subsequent Offering. Eligible Employees may not
participate in more than one Offering at a time. In the event the first or last
day of an Offering Period is not a business day, the Company shall specify the
business day that will be deemed the first or last day, as the case may be, of
the Offering Period.

          6.2  PURCHASE PERIODS. If the Board so determines, in its discretion,
each Offering Period may consist of two (2) or more consecutive purchase periods
having such duration as the Board shall specify (individually, a "PURCHASE
PERIOD"), and the last day of each such Purchase Period shall be a Purchase
Date. In the event the first or last day of a Purchase Period is not a business
day, the Company shall specify the business day that will be deemed the first or
last day, as the case may be, of the Purchase Period.

         6.3   GOVERNMENTAL APPROVAL; STOCKHOLDER APPROVAL. Notwithstanding any
other provision of the Plan to the contrary, any Purchase Right granted pursuant
to the Plan shall be subject to (a) obtaining all necessary governmental
approvals or qualifications of the sale or issuance of the Purchase Rights or
the shares of Stock and (b) obtaining stockholder approval of the Plan.

     7.  PARTICIPATION IN THE PLAN.
         ------------------------- 

         7.1  INITIAL PARTICIPATION. An Eligible Employee shall become a
Participant on the first Offering Date after satisfying the eligibility
requirements of Section 5 and delivering to the Company's payroll office or
other office designated by the Company not later than the close of business for
such office on the last business day before such Offering Date (the
"SUBSCRIPTION DATE") a subscription agreement indicating the Employee's election
to participate in the Plan and authorizing payroll

                                       5
<PAGE>
 
deductions.  An Eligible Employee who does not deliver a subscription agreement
to the Company's payroll or other designated office on or before the
Subscription Date shall not participate in the Plan for that Offering Period or
for any subsequent Offering Period unless such Employee subsequently enrolls in
the Plan by filing a subscription agreement with the Company by the Subscription
Date for such subsequent Offering Period.  The Company may, from time to time,
change the Subscription Date as deemed advisable by the Company in its sole
discretion for proper administration of the Plan.

          7.2  CONTINUED PARTICIPATION. A Participant shall automatically
participate in the Offering Period commencing immediately after the final
Purchase Date of each Offering Period in which the Participant participates
until such time as the Participant (a) ceases to be an Eligible Employee, (b)
withdraws from the Plan pursuant to Section 13.2 or (c) terminates employment as
provided in Section 14. If a Participant automatically may participate in a
subsequent Offering Period pursuant to this Section 7.2, then the Participant is
not required to file any additional subscription agreement for the subsequent
Offering Period in order to continue participation in the Plan. However, a
Participant may file a subscription agreement for a subsequent Offering Period
if the Participant desires to change any of the Participant's elections
contained in the Participant's then effective subscription agreement.

     8.   RIGHT TO PURCHASE SHARES.
          ------------------------ 

          8.1  PURCHASE RIGHT. Except as set forth below, during an Offering
Period each Participant in the Offering Period shall have a Purchase Right
consisting of the right to purchase that number of whole shares of Stock
determined by dividing Twelve Thousand Five Hundred Dollars ($12,500) by the
Fair Market Value of a share of Stock on the Offering Date of the Offering
Period; provided, however, that such number shall not exceed one thousand five
hundred (1,500) shares (the "PER OFFERING SHARE LIMIT"). Shares of Stock may
only be purchased through a Participant's payroll deductions pursuant to Section
10.

          8.2  PRO RATA ADJUSTMENT OF PURCHASE RIGHT. Notwithstanding the
foregoing, if the Board establishes an Offering Period of less than five and 
one-half (5 1/2) months or more than six and one-half (6 1/2) months in 
duration (a) the dollar amount in Section 8.1 shall be determined by multiplying
$2,083.33 by the number of months in the Offering Period and rounding to the
nearest whole dollar, and (b) the Per Offering Share Limit shall be determined
by multiplying 250 shares by the number of months in the Offering Period and
rounding to the nearest whole share. For purposes of the preceding sentence,
fractional months shall be rounded to the nearest whole month.

     9.  PURCHASE PRICE.  The Purchase Price at which each share of Stock may be
         --------------                                                         
acquired in a given Offering Period pursuant to the exercise of all or any
portion of a Purchase Right shall be set by the Board; provided, however, that
the Purchase Price shall not be less than eighty-five percent (85%) of the
lesser of (a) the Fair Market Value of a share of Stock on the Offering Date of
the Offering Period, or (b) the Fair

                                       6
<PAGE>
 
Market Value of a share of Stock on the Purchase Date.  Unless otherwise
provided by the Board prior to the commencement of an Offering Period, the
Purchase Price for that Offering Period shall be eighty-five percent (85%) of
the lesser of (a) the Fair Market Value of a share of Stock on the Offering Date
of the Offering Period, or (b) the Fair Market Value of a share of Stock on the
Purchase Date.

     10.  ACCUMULATION OF PURCHASE PRICE THROUGH PAYROLL DEDUCTION.  Shares of
          --------------------------------------------------------            
Stock which are acquired pursuant to the exercise of all or any portion of a
Purchase Right for an Offering Period may be paid for only by means of payroll
deductions from the Participant's Compensation accumulated during the Offering
Period.  Except as set forth below, the amount of Compensation to be deducted
from a Participant's Compensation on each payday during an Offering Period shall
be determined by the Participant's subscription agreement.

          10.1  COMMENCEMENT OF PAYROLL DEDUCTIONS. Payroll deductions shall
commence on the first payday following the Offering Date and shall continue to
the end of the Offering Period unless sooner altered or terminated as provided
in the Plan.

          10.2  LIMITATIONS ON PAYROLL DEDUCTIONS. The amount deducted from a
Participant's Compensation on any payday during an Offering Period pursuant to
the Participant's subscription agreement shall be in one percent (1%) increments
not exceeding ten percent (10%) of the Participant's Compensation on such
payday. Notwithstanding the foregoing, the Board may change the limits on
payroll deductions effective as of a future Offering Date, as determined by the
Board. Amounts deducted from Compensation shall be reduced by any amounts
contributed by the Participant and applied to the purchase of Company stock
pursuant to any other employee stock purchase plan qualifying under Section 423
of the Code.

          10.3  ELECTION TO DECREASE OR STOP PAYROLL DEDUCTIONS. During an
Offering Period, a Participant may elect to decrease the amount deducted or stop
deductions from his or her Compensation by filing an amended subscription
agreement with the Company on or before the "Change Notice Date." The "CHANGE
NOTICE DATE" shall initially be the seventh (7th) day prior to the end of the
first pay period for which such election is to be effective; however, the
Company may change the Change Notice Date from time to time. A Participant may
not elect to increase the amount deducted from the Participant's Compensation
during an Offering Period.

          10.4  PARTICIPANT ACCOUNTS. Individual Plan accounts shall be
maintained for each Participant. All payroll deductions from a Participant's
Compensation shall be credited to such account and shall be deposited with the
general funds of the Company. All payroll deductions received or held by the
Company may be used by the Company for any corporate purpose.

          10.5  NO INTEREST PAID. Interest shall not be paid on sums deducted
from a Participant's Compensation pursuant to the Plan.

                                       7
<PAGE>
 
          10.6  COMPANY ESTABLISHED PROCEDURES. The Company may, from time to
time, establish or change (a) a minimum required payroll deduction amount for
participation in an Offering, (a) limitations on the frequency or number of
changes in the rate of payroll deduction during an Offering, (c) an exchange
ratio applicable to amounts withheld in a currency other than U.S. dollars, (d)
payroll deduction in excess of or less than the amount designated by a
Participant in order to adjust for delays or mistakes in the Company's
processing of subscription agreements, (e) the date(s) and manner by which the
Fair Market Value of a share of Stock is determined for purposes of
administration of the Plan, or (vi) such other limitations or procedures as
deemed advisable by the Company in the Company's sole discretion which are
consistent with the Plan and in accordance with the requirements of Section 423
of the Code.

     11.  PURCHASE OF SHARES.
          ------------------ 

          11.1  EXERCISE OF PURCHASE RIGHT. On each Purchase Date of an Offering
Period, each Participant who has not withdrawn from the Offering or whose
participation in the Offering has not terminated on or before such Purchase Date
shall automatically acquire pursuant to the exercise of the Participant's
Purchase Right the number of whole shares of Stock determined by dividing the
total amount of the Participant's accumulated payroll deductions for the
Offering Period not previously applied toward the purchase of Stock by the
Purchase Price; provided, however, in no event shall the number of shares
purchased by the Participant during an Offering Period exceed the number of
shares subject to the Participant's Purchase Right. No shares of Stock shall be
purchased on a Purchase Date on behalf of a Participant whose participation in
the Offering or the Plan has terminated on or before such Purchase Date.

          11.2  RETURN OF CASH BALANCE. Any cash balance remaining in the
Participant's Plan account shall be refunded to the Participant as soon as
practicable after the Purchase Date. However, if the cash to be returned to a
Participant pursuant to the preceding sentence is an amount less than the amount
necessary to purchase a whole share of Stock, the Company may establish
procedures whereby such cash is maintained in the Participant's Plan account and
applied toward the purchase of shares of Stock in the subsequent Offering Period
(or Purchase Period, as the case may be).

          11.3  TAX WITHHOLDING. At the time a Participant's Purchase Right is
exercised, in whole or in part, or at the time a Participant disposes of some or
all of the shares of Stock he or she acquires under the Plan, the Participant
shall make adequate provision for the foreign, federal, state and local tax
withholding obligations of the Participating Company Group, if any, which arise
upon exercise of the Purchase Right or upon such disposition of shares,
respectively. The Participating Company Group may, but shall not be obligated
to, withhold from the Participant's compensation the amount necessary to meet
such withholding obligations.

          11.4  EXPIRATION OF PURCHASE RIGHT. Any portion of a Participant's
Purchase Right remaining unexercised after the end of the Offering Period to
which the Purchase Right relates shall expire immediately upon the end of the
Offering Period.

          11.5  REPORTS TO PARTICIPANTS. Each Participant who has exercised all
or part of his or her Purchase Right shall receive, as soon as practicable after
the Purchase Date, a report of such Participant's Plan account setting forth the
total payroll deductions accumulated, the number of shares of Stock purchased,
the Purchase Price for such shares, the date of purchase and the remaining cash
balance to be refunded or retained in the Participant's Plan account pursuant to
Section 11.2, if any. In addition, each Participant shall be provided
information concerning the Company equivalent to that information generally made
available to the Company's common stockholders.

     12.  LIMITATIONS ON PURCHASE OF SHARES; RIGHTS AS A STOCKHOLDER.
          ---------------------------------------------------------- 

          12.1  FAIR MARKET VALUE LIMITATION.  Notwithstanding any other
provision of the Plan, no Participant shall be entitled to purchase shares of
Stock under the Plan (or any other employee stock purchase plan intended to meet
the requirements of Section 423 of the Code sponsored by the Company or a Parent
Corporation or Subsidiary Corporation) at a rate which exceeds $25,000 (or such
other limit as may be imposed by the Code) in Fair Market Value for each
calendar year in which the Participant participates in the Plan (or any other
employee stock purchase plan described in this sentence).  For purposes of the
preceding sentence, the Fair Market Value of shares purchased during a given
Offering Period shall be determined as of the Offering Date for such Offering
Period.  The limitation described in this Section 12.1 shall be applied in
conformance with applicable regulations under Section 423 of the Code.

          12.2  PRO RATA ALLOCATION.  In the event the number of shares of Stock
which might be purchased by all Participants in the Plan exceeds the number of
shares of Stock available in the Plan as provided in Section 4.1, the Company
shall make a pro rata allocation of the remaining shares in as uniform a manner
as shall be practicable and as the Company shall determine to be equitable.

          12.3  RIGHTS AS A STOCKHOLDER AND EMPLOYEE.  A Participant shall have
no rights as a stockholder by virtue of the Participant's participation in the
Plan until the date of the issuance of a stock certificate for the shares of
Stock being purchased pursuant to the exercise of the Participant's Purchase
Right.  No adjustment shall be made for cash dividends or distributions or other
rights for which the record date is prior to the date such stock certificate is
issued.  Nothing herein shall confer upon a Participant any right to continue in
the employ of the Participating Company Group or interfere in any way with any
right of the Participating Company Group to terminate the Participant's
employment at any time.

                                       9

     13.  WITHDRAWAL.
          ---------- 

          13.1  WITHDRAWAL FROM AN OFFERING.  A Participant may withdraw from an
Offering by signing and delivering to the Company's payroll or other designated
office a written notice of withdrawal on a form provided by the Company for such
purpose.  Such withdrawal may be elected at any time prior to the end of an
Offering Period; provided, however, if a Participant withdraws after a Purchase
Date, the withdrawal shall not affect shares of Stock acquired by the
Participant on such Purchase Date.  Unless otherwise indicated, withdrawal from
an Offering shall not result in a withdrawal from the Plan or any succeeding
Offering therein.  A Participant is prohibited from again participating in an
Offering at any time following withdrawal from such Offering.  The Company may
impose, from time to time, a requirement that the notice of withdrawal be on
file with the Company's payroll office or other designated office for a
reasonable period prior to the effectiveness of the Participant's withdrawal
from an Offering.

          13.2  WITHDRAWAL FROM THE PLAN.  A Participant may withdraw from the
Plan by signing and delivering to the Company's payroll office or other
designated office a written notice of withdrawal on a form provided by the
Company for such purpose.  Withdrawals made after a Purchase Date shall not
affect shares of Stock acquired by the Participant on such Purchase Date.  In
the event a Participant voluntarily elects to withdraw from the Plan, the
Participant may not resume participation in the Plan during the same Offering
Period, but may participate in any subsequent Offering under the Plan by again
satisfying the requirements of Sections 5 and 7.1.  The Company may impose, from
time to time, a requirement that the notice of withdrawal be on file with the
Company's payroll office or other designated office for a reasonable period
prior to the effectiveness of the Participant's withdrawal from the Plan.

          13.3  RETURN OF PAYROLL DEDUCTIONS.  Upon a Participant's withdrawal
from an Offering or the Plan pursuant to Sections 13.1 or 13.2, respectively,
the Participant's accumulated payroll deductions which have not been applied
toward the purchase of shares of Stock shall be returned as soon as practicable
after the withdrawal, without the payment of any interest, to the Participant,
and the Participant's interest in the Offering or the Plan, as applicable, shall
terminate.  Such accumulated payroll deductions may not be applied to any other
Offering under the Plan.

          13.4  WAIVER OF WITHDRAWAL RIGHT.  The Company may, from time to time,
establish a procedure pursuant to which a Participant may elect, at least six
(6) months prior to a Purchase Date, to have all payroll deductions accumulated
in his or her Plan account as of such Purchase Date applied to purchase shares
of Stock under the Plan, and (a) to waive his or her right to withdraw from the
Offering or the Plan and (b) to waive his or her right to increase, decrease, or
cease payroll deductions under the Plan from his or her Compensation during the
period ending on such Purchase Date.  Such election shall be made in writing on
a form provided by the Company for such purpose and must be delivered to the
Company not later than the

                                       10
<PAGE>
 
close of business on the day preceding the date which is six (6) months before
the Purchase Date for which such election is to first be effective.

     14.  TERMINATION OF EMPLOYMENT OR ELIGIBILITY.  Termination of a
          ----------------------------------------                   
Participant's employment with the Participating Company Group for any reason,
including retirement, disability or death or the failure of a Participant to
remain an Eligible Employee, shall terminate the Participant's participation in
the Plan immediately.  In such event, the payroll deductions credited to the
Participant's Plan account since the last Purchase Date shall, as soon as
practicable, be returned to the Participant or, in the case of the Participant's
death, to the Participant's legal representative, and all of the Participant's
rights under the Plan shall terminate.  Interest shall not be paid on sums
returned to a Participant pursuant to this Section 14.  A Participant whose
participation has been so terminated may again become eligible to participate in
the Plan by again satisfying the requirements of Sections 5 and 7.1.

     15.  TRANSFER OF CONTROL.
          ------------------- 

          15.1 DEFINITIONS.

               (a)  An "OWNERSHIP CHANGE EVENT" shall be deemed to have 
occurred if any of the following occurs with respect to the Company: (i) the
direct or indirect sale or exchange in a single or series of related
transactions by the stockholders of the Company of more than fifty percent (50%)
of the voting stock of the Company; (ii) a merger or consolidation in which the
Company a party; (iii) the sale, exchange, or transfer of all or substantially
all of the assets of the Company; or (iv) a liquidation or dissolution of the
Company.

               (b)  A "TRANSFER OF CONTROL" shall mean an Ownership Change 
Event or a series of related Ownership Change Events (collectively, the
"TRANSACTION") wherein the stockholders of the Company immediately before the
Transaction do not retain immediately after the Transaction, in substantially
the same proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

          15.2 EFFECT OF TRANSFER OF CONTROL ON PURCHASE RIGHTS.  In the event
of a Transfer of Control, the surviving, continuing, successor, or purchasing
corporation

                                       11
<PAGE>
 
or parent corporation thereof, as the case may be (the "ACQUIRING CORPORATION"),
may assume the Company's rights and obligations under the Plan or substitute
substantially equivalent Purchase Rights for stock of the Acquiring Corporation.
If the Acquiring Corporation elects not to assume or substitute for the
outstanding Purchase Rights, the Board may, in its sole discretion and
notwithstanding any other provision herein to the contrary, adjust the Purchase
Date of the then current Purchase Period to a date on or before the date of the
Transfer of Control, but shall not adjust the number of shares of Stock subject
to any Purchase Right.  All Purchase Rights which are neither assumed or
substituted for by the Acquiring Corporation in connection with the Transfer of
Control nor exercised as of the date of the Transfer of Control shall terminate
and cease to be outstanding effective as of the date of the Transfer of Control.
Notwithstanding the foregoing, if the corporation the stock of which is subject
to the outstanding Purchase Rights immediately prior to an Ownership Change
Event described in Section 15.1(a)(i) constituting a Transfer of Control is the
surviving or continuing corporation and immediately after such Ownership Change
Event less than fifty percent (50%) of the total combined voting power of its
voting stock is held by another corporation or by other corporations that are
members of an affiliated group within the meaning of section 1504(a) of the Code
without regard to the provisions of section 1504(b) of the Code, the outstanding
Purchase Rights shall not terminate unless the Board otherwise provides in its
sole discretion.

     16.  NONTRANSFERABILITY OF PURCHASE RIGHTS.  A Purchase Right may not be
          -------------------------------------                              
transferred in any manner otherwise than by will or the laws of descent and
distribution and shall be exercisable during the lifetime of the Participant
only by the Participant.  The Company, in its absolute discretion, may impose
such restrictions on the transferability of the shares purchasable upon the
exercise of a Purchase Right as it deems appropriate and any such restriction
shall be set forth in the respective subscription agreement and may be referred
to on the certificates evidencing such shares.

     17.  RESTRICTION ON ISSUANCE OF SHARES.  The issuance of shares under the
          ---------------------------------                                   
Plan shall be subject to compliance with all applicable requirements of foreign,
federal or state law with respect to such securities.  A Purchase Right may not
be exercised if the issuance of shares upon such exercise would constitute a
violation of any applicable foreign, federal or state securities laws or other
law or regulations.  In addition, no Purchase Right may be exercised unless (a)
a registration statement under the Securities Act of 1933, as amended, shall at
the time of exercise of the Purchase Right be in effect with respect to the
shares issuable upon exercise of the Purchase Right, or (b) in the opinion of
legal counsel to the Company, the shares issuable upon exercise of the Purchase
Right may be issued in accordance with the terms of an applicable exemption from
the registration requirements of said Act.  The inability of the Company to
obtain from any regulatory body having jurisdiction the authority, if any,
deemed by the Company's legal counsel to be necessary to the lawful issuance and
sale of any shares under the Plan shall relieve the Company of any liability in
respect of the failure to issue or sell such shares as to which such requisite
authority shall not have been obtained.  As a condition to the exercise of a

                                       12
<PAGE>
 
Purchase Right, the Company may require the Participant to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with
any applicable law or regulation, and to make any representation or warranty
with respect thereto as may be requested by the Company.

     18.  LEGENDS.  The Company may at any time place legends or other
          -------                                                     
identifying symbols referencing any applicable foreign, federal or state
securities law restrictions or any provision convenient in the administration of
the Plan on some or all of the certificates representing shares of Stock issued
under the Plan.  The Participant shall, at the request of the Company, promptly
present to the Company any and all certificates representing shares acquired
pursuant to a Purchase Right in the possession of the Participant in order to
carry out the provisions of this Section.  Unless otherwise specified by the
Company, legends placed on such certificates may include but shall not be
limited to the following:

          "THE SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE
CORPORATION TO THE REGISTERED HOLDER UPON THE PURCHASE OF SHARES UNDER AN
EMPLOYEE STOCK PURCHASE PLAN AS DEFINED IN SECTION 423 OF THE INTERNAL REVENUE
CODE OF 1986, AS AMENDED.  THE TRANSFER AGENT FOR THE SHARES EVIDENCED HEREBY
SHALL NOTIFY THE CORPORATION IMMEDIATELY OF ANY TRANSFER OF THE SHARES BY THE
REGISTERED HOLDER HEREOF MADE ON OR BEFORE ______________, 19__.  THE REGISTERED
HOLDER SHALL HOLD ALL SHARES PURCHASED UNDER THE PLAN IN THE REGISTERED HOLDER'S
NAME (AND NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE."

     19.  NOTIFICATION OF SALE OF SHARES.  The Company may require the
          ------------------------------                              
Participant to give the Company prompt notice of any disposition of shares
acquired by exercise of a Purchase Right within two years from the date of
granting such Purchase Right or one year from the date of exercise of such
Purchase Right.  The Company may require that until such time as a Participant
disposes of shares acquired upon exercise of a Purchase Right, the Participant
shall hold all such shares in the Participant's name (and not in the name of any
nominee) until the lapse of the time periods with respect to such Purchase Right
referred to in the preceding sentence.  The Company may direct that the
certificates evidencing shares acquired by exercise of a Purchase Right refer to
such requirement to give prompt notice of disposition.

     20.  AMENDMENT OR TERMINATION OF THE PLAN.  The Board may at any time amend
          ------------------------------------                                  
or terminate the Plan, except that (a) such termination shall not affect
Purchase Rights previously granted under the Plan, except as permitted under the
Plan, and (b) no amendment may adversely affect a Purchase Right previously
granted under the Plan (except to the extent permitted by the Plan or as may be
necessary to qualify the Plan as an employee stock purchase plan pursuant to
Section 423 of the Code or to obtain qualification or registration of the shares
of Stock under applicable foreign, federal or state securities laws).  In
addition, an amendment to the Plan must be approved by the stockholders of the
Company

                                       13
<PAGE>
 
within twelve (12) months of the adoption of such amendment if such amendment
would authorize the sale of more shares than are authorized for issuance under
the Plan or would change the definition of the corporations that may be
designated by the Board as Participating Companies.

     IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that
the foregoing Visigenic Software, Inc. 1996 Employee Stock Purchase Plan was
duly adopted by the Board of Directors of the Company on June 17, 1996.

deductions will be accumulated for the purchase of shares of common stock of the
Company at the applicable purchase price determined in accordance with the Plan.
I further understand that, except as otherwise set forth in the Plan, I will
automatically purchase shares on each Purchase Date under the Plan unless I
withdraw from the Plan or from the Offering by giving written notice on a form
provided by the Company or unless my employment terminates.

use of the term "or" shall include the conjunctive as well as the disjunctive.

     3.   ADMINISTRATION.
          -------------- 

          3.1  ADMINISTRATION BY THE BOARD.  The Plan shall be administered by 
the Board, including any duly appointed Committee of the Board. All questions of
interpretation of the Plan or of any Option shall be determined by the Board,
and such determinations shall be final and binding upon all persons having an
interest in the Plan or such Option. Any officer of a Participating Company
shall have the authority to act on behalf of the Company with respect to any
matter, right, obligation, determination or election which is the responsibility
of or which is allocated to the Company herein, provided the officer has

          3.2  LIMITATIONS ON AUTHORITY OF THE BOARD. Notwithstanding any other 
provision herein to the contrary, the Board shall have no authority, discretion,
or power to select the Outside Directors who will receive Options, to set the
exercise price of the Options, to determine the number of shares of Stock to be
subject to an Option or the time at which an Option shall be granted, to
establish the duration of an Option, or to alter any other terms or conditions
specified in the Plan, except in the sense of administering the Plan subject to
the provisions of the Plan.

     4.   SHARES SUBJECT TO PLAN.
          ---------------------- 

          4.1  MAXIMUM NUMBER OF SHARES ISSUABLE.  Subject to adjustment as 
provided in Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be two hundred thousand (200,000) and shall
consist of authorized but unissued shares or reacquired shares of Stock or any
combination thereof. If an outstanding Option for any reason expires or is
terminated or canceled or shares of Stock acquired, subject to repurchase, upon
the exercise of an Option are repurchased by the Company, the shares of Stock
allocable to the unexercised portion of such Option, or such repurchased shares
of Stock, shall again be available for issuance under the Plan.

          4.2  ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.  In the event of 
any stock dividend, stock split, reverse stock split, recapitalization,
combination, reclassification or similar change in the capital structure of the
Company, appropriate adjustments shall be made in the number and class of shares
subject to the Plan, to the "Initial Option" and "Annual Option" (as defined in
Section 6.1), and to any outstanding Options, and in the exercise price of any
outstanding Options. If a majority of the shares which are of the same class as
the shares that are subject to outstanding Options are exchanged for, converted
into, or otherwise become (whether or not pursuant to a Transfer of Control as
defined in Section 8.1) shares of another corporation (the "NEW SHARES"), the
Board may unilaterally amend the outstanding Options to provide that such
Options are exercisable for New Shares. In the event of any such amendment, the
number of shares subject to, and the exercise price of, the outstanding Options
shall be adjusted in a fair and equitable manner as determined by the Board, in
its sole discretion. Notwithstanding the foregoing, any fractional share
resulting from an adjustment pursuant to this Section 4.2 shall be rounded down
to the nearest whole number, and in no event may the exercise price of any
Option be decreased to an amount less than the par value, if any, of the stock
subject to the Option.

     5.   ELIGIBILITY AND TYPE OF OPTIONS.
          ------------------------------- 

          5.1  PERSONS ELIGIBLE FOR OPTIONS.  An Option shall be granted only 
to a person who, at the time of grant, is an Outside Director.

                                       4
<PAGE>
 
          5.2  OPTIONS AUTHORIZED.  Options shall be nonstatutory stock 
options; that is, options which are not treated as incentive stock options
within the meaning of Section 422(b) of the Code.

     6.   TERMS AND CONDITIONS OF OPTIONS.  Options shall be evidenced by Option
          -------------------------------                                       
Agreements specifying the number of shares of Stock covered thereby, in such
form as the Board shall from time to time establish.  Option Agreements may
incorporate all or any of the terms of the Plan by reference and shall comply
with and be subject to the following terms and conditions:

          6.1  AUTOMATIC GRANT OF OPTIONS.  Subject to execution by an Outside 
Director of the appropriate Option Agreement, Options shall be granted 
automatically and without further action of the Board, as follows:

               (a) INITIAL OPTION.  Each Outside Director shall be granted an 
initial Option as follows (an "INITIAL OPTION"):

                   (i)   Each Outside Director who was an Outside Director on 
the Effective Date shall be granted an Option to purchase fifteen thousand
(15,000) shares of Stock on the day following the first annual meeting of the
Company's stockholders after the Effective Date.

                   (ii)  Each person who is first elected or appointed as an 
Outside Director after the Effective Date shall be granted an Option to purchase
fifteen thousand (15,000) shares of Stock on the date of such initial election
or appointment.

               (b) ANNUAL OPTION.  Each Outside Director shall be granted an 
Option to purchase five thousand (5,000) shares of Stock (the "ANNUAL OPTION")
on each anniversary of the date of grant of his or her Initial Option.

               (c) RIGHT TO DECLINE OPTION.  Notwithstanding the foregoing, any
person may elect not to receive an Option by delivering written notice of such
election to the Board no later than the day prior to the date such Option would
otherwise be granted.  A person so declining an Option shall receive no payment
or other consideration in lieu of such declined Option.  A person who has
declined an Option may revoke such election by delivering written notice of such
revocation to the Board no later than the day prior to the date such Option
would be granted pursuant to Section 6.1(a) or (b), as the case may be.

          6.2  EXERCISE PRICE.  The exercise price per share of Stock subject 
to an Option shall be the Fair Market Value of a share of Stock on the date 
the Option is granted.

          6.3  EXERCISE PERIOD.  Each Option shall terminate and cease to be 
exercisable on the date ten (10) years after the date
of grant of the Option unless earlier terminated pursuant to the terms of the
Plan or the Option Agreement.

                                       5
<PAGE>
 
          6.4  RIGHT TO EXERCISE OPTIONS.

               (a) INITIAL OPTION.  Except as otherwise provided in the Plan 
or in the Option Agreement, an Initial Option shall (i) first become exercisable
on the date which is six (6) months after the date on which the Initial Option
was granted (the "INITIAL OPTION VESTING DATE"); and (ii) be exercisable on and
after the Initial Option Vesting Date and prior to the termination thereof in an
amount equal to the number of shares of Stock initially subject to the Initial
Option multiplied by the Vested Ratio as set forth below, less the number of
shares previously acquired upon exercise thereof. The Vested Ratio described in
the preceding sentence shall be determined as follows:

                                                         Vested Ratio
                                                         ------------
 
               Prior to Initial Option Vesting Date                 0
 
               On Initial Option Vesting Date,                    1/8
               provided the Optionee's Service
               is continuous from the date of grant
               of the Initial Option until the
               Initial Option Vesting Date
 
               Plus
               ---- 
 
               For each full month of                            1/48
               of the Optionee's continuous
               Service from the Initial Option
               Vesting Date until the Vested
               Ratio equals 1/1, an additional

               (b) ANNUAL OPTION.  Except as otherwise provided in the Plan or 
in the Option Agreement, an Annual Option shall (i) first become exercisable on
the date which is thirty-seven (37) months after the date on which the Annual
Option was granted (the "ANNUAL OPTION VESTING DATE"); and (ii) be exercisable
on and after the Annual Option Vesting Date and prior to the termination thereof
in an amount equal to the number of shares of Stock initially subject to the
Annual Option multiplied by the Vested Ratio as set forth below, less the number
of shares previously acquired upon exercise thereof. The Vested Ratio described
in the preceding sentence shall be determined as follows:

                                       6
<PAGE>
 
                                                   Vested Ratio
                                                   ------------
 
               Prior to Annual Option                         
               Vesting Date                                   0
 
               On Annual Option Vesting Date,              1/12
               provided the Optionee's Service
               is continuous from the date of grant
               of the Annual Option until the
               Annual Option Vesting Date
 
               Plus
               ---- 
 
               For each full month of                      1/12
               of the Optionee's continuous
               Service from the Annual
               Option Vesting Date until the
               Vested Ratio equals 1/1, an additional

          6.5  PAYMENT OF EXERCISE PRICE.

               (a) FORMS OF CONSIDERATION AUTHORIZED.  Except as otherwise 
provided below, payment of the exercise price for the number of shares of Stock
being purchased pursuant to any Option shall be made (i) in cash, by check, or
cash equivalent, (ii) by tender to the Company of shares of Stock owned by the
Optionee having a Fair Market Value not less than the exercise price, (iii) by
the assignment of the proceeds of a sale or loan with respect to some or all of
the shares being acquired upon the exercise of the Option (including, without
limitation, through an exercise complying with the provisions of Regulation T as
promulgated from time to time by the Board of Governors of the Federal Reserve
System) (a "CASHLESS EXERCISE"), or (iv) by any combination thereof.

               (b) TENDER OF STOCK.  Notwithstanding the foregoing, an Option 
may not be exercised by tender to the Company of shares of Stock to the extent
such tender of Stock would constitute a violation of the provisions of any law,
regulation or agreement restricting the redemption of the Company's stock.
Unless otherwise provided by the Board, an Option may not be exercised by tender
to the Company of shares of Stock unless such shares either have been owned by
the Optionee for more than six (6) months or were not acquired, directly or
indirectly, from the Company.

               (c) CASHLESS EXERCISE.  The Company reserves, at any and all 
times, the right, in the Company's sole and absolute discretion, to establish,
decline to approve or terminate any program or procedures for the exercise of
Options by means of a Cashless Exercise.

                                       7
<PAGE>
 
          6.6  TAX WITHHOLDING.  The Company shall have the right, but not the
obligation, to deduct from the shares of Stock issuable upon the exercise of an
Option, or to accept from the Optionee the tender of, a number of whole shares
of Stock having a Fair Market Value equal to all or any part of the federal,
state, local and foreign taxes, if any, required by law to be withheld by the
Participating Company Group with respect to such Option or the shares acquired
upon exercise thereof.  Alternatively or in addition, in its sole discretion,
the Company shall have the right to require the Optionee to make adequate
provision for any such tax withholding obligations of the Participating Company
Group arising in connection with the Option or the shares acquired upon exercise
thereof.  The Company shall have no obligation to deliver shares of Stock until
the Participating Company Group's tax withholding obligations have been
satisfied.

     7.   STANDARD FORM OF OPTION AGREEMENT.
          --------------------------------- 

          7.1  INITIAL OPTION.  Unless otherwise provided for by the Board at
the time an Initial Option is granted, each Initial Option shall comply with and
be subject to the terms and conditions set forth in the form of Nonstatutory
Stock Option Agreement for Outside Directors (Initial Option) adopted by the
Board concurrently with its adoption of the Plan and as amended from time to
time.

          7.2  ANNUAL OPTION.  Unless otherwise provided for by the Board at the
time an Annual Option is granted, each Annual Option shall comply with and be
subject to the terms and conditions set forth in the form of Nonstatutory Stock
Option Agreement for Outside Directors (Annual Option) adopted by the Board
concurrently with its adoption of the Plan and as amended from time to time.

          7.3  AUTHORITY TO VARY TERMS.  Subject to the limitations set forth in
Section 3.2, the Board shall have the authority from time to time to vary the
terms of any of the standard forms of Option Agreement described in this Section
7 either in connection with the grant or amendment of an individual Option or in
connection with the authorization of a new standard form or forms; provided,
however, that the terms and conditions of any such new, revised or amended
standard form or forms of Option Agreement shall be in accordance with the terms
of the Plan.  Such authority shall include, but not by way of limitation, the
authority to grant Options which are immediately exercisable subject to the
Company's right to repurchase any unvested shares of Stock acquired by the
Optionee upon the exercise of an Option in the event such Optionee's Service is
terminated for any reason.  In no event, however, shall the Board be permitted
to vary the terms of any standard form of Option Agreement if such change would
cause the Plan to cease to qualify as a formula plan pursuant to Rule 16b-3 at
any such time as any class of equity security of the Company is registered
pursuant to Section 12 of the Exchange Act.

     8.   TRANSFER OF CONTROL.
          ------------------- 

          8.1  DEFINITIONS.

               (a)  An "OWNERSHIP CHANGE EVENT" shall be deemed to have 
occurred if any of the following occurs with respect to the Company:

                    (i)    the direct or indirect sale or exchange in a single 
or series of related transactions by the stockholders of the Company of more
than fifty percent (50%) of the voting stock of the Company;

                    (ii)   a merger or consolidation in which the Company is a
party;

                    (iii)  the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                    (iv)   a liquidation or dissolution of the Company.

               (b)  A "TRANSFER OF CONTROL" shall mean an Ownership Change 
Event or a series of related Ownership Change Events (collectively, the
"TRANSACTION") wherein the stockholders of the Company immediately before the
Transaction do not retain immediately after the Transaction, in substantially
the same proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "TRANSFEREE
CORPORATION(S)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

          8.2  EFFECT OF TRANSFER OF CONTROL ON OPTIONS.  In the event of a
Transfer of Control, any unexercisable or unvested portion of the outstanding
Options shall be immediately exercisable and vested in full as of the date ten
(10) days prior to the date of the Transfer of Control.  Any exercise or vesting
of any Option that was permissible solely by reason of this Section 8.2 shall be
conditioned upon the consummation of the Transfer of Control.  In addition, the
surviving, continuing, successor, or purchasing corporation or parent
corporation thereof, as the case may be (the "ACQUIRING CORPORATION"), may
either assume the Company's rights and obligations under outstanding Options or
substitute for outstanding Options substantially equivalent options for the
Acquiring Corporation's

                                       9
<PAGE>
 
stock.  Any Options which are neither assumed or substituted for by the
Acquiring Corporation in connection with the Transfer of Control nor exercised
as of the date of the Transfer of Control shall terminate and cease to be
outstanding effective as of the date of the Transfer of Control.
Notwithstanding the foregoing, shares acquired upon exercise of an Option prior
to the Transfer of Control and any consideration received pursuant to the
Transfer of Control with respect to such shares shall continue to be subject to
all applicable provisions of the Option Agreement evidencing such Option except
as otherwise provided in such Option Agreement.  Furthermore, notwithstanding
the foregoing, if the corporation the stock of which is subject to the
outstanding Options immediately prior to an Ownership Change Event described in
Section 8.1(a)(i) constituting a Transfer of Control is the surviving or
continuing corporation and immediately after such Ownership Change Event less
than fifty percent (50%) of the total combined voting power of its voting stock
is held by another corporation or by other corporations that are members of an
affiliated group within the meaning of Section 1504(a) of the Code without
regard to the provisions of Section 1504(b) of the Code, the outstanding Options
shall not terminate.

     9.   TRANSFERABILITY OF OPTIONS.  Except as provided below, an Option may
          --------------------------                                          
be exercised during the lifetime of the Optionee only by the Optionee or the
Optionee's guardian or legal representative and may not be assigned or
transferred in any manner except by will or by the laws of descent and
distribution.  Notwithstanding the foregoing and with the consent of the
Company, to the extent that the restrictions of the preceding sentence are not
required for compliance with the conditions of Rule 16b-3 or any other
applicable law or regulation, an Optionee may, without receipt of any
consideration, transfer the Option to, and the Option may be exercised by, only
the following: (a) the Optionee's immediate family, (b) a trust for the benefit
of the Optionee or the Optionee's immediate family, or (c) a partnership in
which only the Optionee's immediate family and the Optionee are partners
(collectively, the "PERMITTED TRANSFEREES").  For purposes of this Section 5,
"immediate family" shall mean the Optionee's children, grandchildren or spouse.
As a condition to such transfer, each Permitted Transferee to whom the Option or
any interest therein is transferred shall agree in writing (in a form
satisfactory to the Company) to be bound by all of the terms and conditions of
the Option.

     10.  INDEMNIFICATION.  In addition to such other rights of indemnification
          ---------------                                                      
as they may have as members of the Board or officers or employees of the
Participating Company Group, members of the Board and any officers or employees
of the Participating Company Group to whom authority to act for the Board is
delegated shall be indemnified by the Company against all reasonable expenses,
including attorneys' fees, actually and necessarily incurred in connection with
the defense of any action, suit or proceeding, or in connection with any appeal
therein, to which they or any of them may be a party by reason of any action
taken or failure to act under or in connection with the Plan, or any right
granted hereunder, and against all amounts paid by them in settlement thereof
(provided such settlement is approved by independent legal counsel selected by
the Company) or paid by them in satisfaction of a judgment in any such action,
suit or proceeding,

                                       10
<PAGE>
 
except in relation to matters as to which it shall be adjudged in such action,
suit or proceeding that such person is liable for gross negligence, bad faith or
intentional misconduct in duties; provided, however, that within sixty (60) days
after the institution of such action, suit or proceeding, such person shall
offer to the Company, in writing, the opportunity at its own expense to handle
and defend the same.

     11.  TERMINATION OR AMENDMENT OF PLAN.  The Board may terminate or amend
          --------------------------------                                   
the Plan at any time.  However, subject to changes in the law or other legal
requirements that would permit otherwise, without the approval of the Company's
stockholders, there shall be (a) no increase in the total number of shares of
Stock that may be issued under the Plan (except by operation of the provisions
of Section 4.2), and (b) no expansion in the class of persons eligible to
receive Options.  Furthermore, to the extent required by Rule 16b-3, provisions
of the Plan addressing eligibility to participate in the Plan and the amount,
price and timing of Options shall not be amended more than once every six (6)
months, other than to comport with changes in the Code, the Employee Retirement
Income Security Act of 1974, as amended, or the rules thereunder.  In any event,
no termination or amendment of the Plan may adversely affect any then
outstanding Option, or any unexercised portion thereof, without the consent of
the Optionee, unless such termination or amendment is necessary to comply with
any applicable law or government regulation.

     IN WITNESS WHEREOF, the undersigned Secretary of the Company certifies that
the foregoing Visigenic Software, Inc. 1996 Outside Directors Stock Option Plan

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

     This Sublease Agreement (the "Sublease"), dated as of January 1, 1996, is 
entered into by and between Visigenic Software, Inc., a Delaware Corporation, 
("Sublessor") and AT Systems, a California Corporation (the "Sublessee").


                                   WITNESSETH
                                   ----------

     WHEREAS, by Lease dated March 7, 1993 as amended December 20, 1995 (the 
"Base Lease"), Sublessor leases from San Mateo Offices Limited, a California 
Limited Partnership, (the "Landlord") certain premises at 951 Mariner's Island 
Blvd.  (the "Base Lease Premises") (to the extent that the Base Lease Premises 
are part of a larger structure, shall be referred to herein as the "Building"); 
and

     WHEREAS, Sublessor is willing to Sublease to Sublessee and Sublessee is 
willing to Sublease from Sublessor, a portion of the Base Lease Premises (as may
be applicable), as more fully described herein, on the terms and conditions set 
forth herein.

     NOW, THEREFORE, Sublessor and Sublessee agree as follows:

     1.  Premises. Sublessor hereby Subleases to Sublessee and Sublessee hereby 
         --------
Subleases and takes from Sublessor approximately 3,928 rentable square feet of 
space in the Base Lease Premises, such Base Lease Premises being known as suite
430, with such subleased space located substantially as shown on Exhibit "A" 
attached hereto and made a part hereof(the "Demised Premises").

     2.  Term. The term of this Sublease shall commerce on February 1, 1996, and
         ----
shall expire on January 31, 1997, unless terminated sooner pursuant to the 
provisions hereof.

     3.  Base Lease Incorporated.
         -----------------------
           A. Except as set forth herein, this subletting shall be on the same
terms and conditions as are contained in the Base Lease, as set forth on Exhibit
"B" attached hereto. Further, Sublessee acknowledges and agrees that this
Sublease shall be in all respects subject and subordinate to the Base Lease.
Nothing contained in this Sublease shall be deemed to confer upon Sublessee any
rights which are in conflict with the Base Lease. Sublessee shall not do or
permit to be done any act or thing which would contravene the terms of the Base
Lease, and the Base Lease shall govern in the event of a conflict with this
Sublease. In the event that the Base Lease is cancelled or terminated for any
reason, the term of this Sublease shall automatically terminate simultaneously
therewith.

           B. Sublessor represents that the Base Lease is in full force and 
effect, without default to the knowledge of Sublessor on the part of either 
party thereto.  Sublessor shall perform all obligations of the tenant under the 
Master Lease not made the responsibility of Sublessee by this Sublease.  
Sublessor shall use its best efforts to


                                       1





<PAGE>
 
enforce the obligations of Landlord under the Base Lease for the benefit of 
Sublessee, including the obligation to provide utilities and services to the 
Demised Premises.

     4.  Use.  During the term hereof, Sublessee shall use and occupy the
         ---   
Demised Premises for general office use and related services, and for no other 
purpose.

     5.  Rent.
         ----

           A. Rent.  As rental for the Demised Premises, Sublessee shall pay
              ----
Landlord a base rental of Eight Thousand Six Hundred Forty Two Dollars 
($8,642.00) per month from commencement through January 31, 1997, without 
set-off or deduction, due and payable in advance on the first day of each month 
during the term hereof.  In the event this Sublease commences or terminates on 
other than the last day of any particular month, all rentals hereunder shall be 
prorated.

           B.  Additional Rent: Increased in Operating Costs and Taxes.
               -------------------------------------------------------

                 (1)  Definitions.  For purposes of this Sublease the following
                      -----------
terms shall be defined as follows:

                       (a)  "Base Operating Costs and Taxes" means the Gross 
Operating Costs and Taxes incurred for the calendar year 1995 (excluding, 
therefrom, however, any gross operating costs of a nature that would not be 
ordinarily and regularly incurred in each and every calendar year);

                       (b)  "Operating Costs" means the total Gross Operating 
Costs for any calendar year divided by the number of rentable square feet of 
office space in the Building.  Operating Costs for any year during which average
occupancy of the Building is less than one hundred percent (100%) shall be 
calculated based upon the Gross Operating Costs that would have been incurred if
the Building were so occupied during the entire calendar year.  Sublessee's 
Share of Operating Costs shall not be reduced as a result of Sublessee's 
performing for itself any of the services that Landlord provides for the 
Property or the tenants of the Property.

                       (c)  "Taxes" means the total Gross Taxes for any calendar
year divided by the number of rentable square feet in the building.  Taxes for 
any year during which average occupancy of the Building is less than one hundred
percent (100%) shall be calculated based upon the Gross Taxes that would have 
been incurred if the Building were so occupied during the entire calendar year.

                       (d)  "Sublessee's Share" means an amount equal to the 
number of rentable square feet of office space in the Premises multiplied
by any increases in Operating Costs and Taxes over Base Operating Costs and 
Taxes.

                                       2
<PAGE>
 
        (2)  Additional Rent. If Operating Costs and Taxes for any calendar year
             ---------------
during the term of this Sublease exceed Base Operating Costs and Taxes,
Sublessee shall pay Landlord as "Additional Rent", Sublessee's Share of such
increase in Operating Costs and Taxes (whether such increase, in the case of
Taxes, is caused by changes in valuation, rate or other factors or
circumstances).
       
     C. Security Deposit. Upon full execution of this Sublease, Sublessee will 
        ----------------- 
pay to Sublessor the sum of Eight Thousand Six Hundred Forty-Two ($8,642.00), as
security for the full and faithful performance of every provision of this 
Sublease to be performed by Sublessee.

     If Sublessee defaults with respect to any provisions of this Sublease, 
including but not limited to the provisions relating to the payment of rent, 
repair or damage to the premises caused by Sublessee and/or cleaning the 
Premises upon termination of this Sublease, Sublessor may use, apply or retain 
all or any part of this security deposit for the payment of any rent, or any 
other sum in default, the repair of such damage to the premises, to the cost of 
such cleaning or for the payment of any other amount which Sublessor may spend 
or become obligated to spend by reason of Sublessee's default or to compensate 
Sublessor for any other loss or damage which Sublessor may suffer by reason of 
Sublessee's default to the full extent permitted by law.

     If any portion of said deposit is so used or applied, Sublessee shall 
within ten (10) days after written demand therefor, deposit cash with Sublessor 
in the amount sufficient to restore the security deposit to its original amount 
and Sublessee's failure to do so shall be a material breach of this Sublease. 
Sublessor shall not be required to keep this security deposit separate from its 
general funds, and Sublessee shall not be entitled to interest on such deposit.

     The security deposit, or so much thereof as has not been properly applied
to cure any default by Sublessee hereunder, shall be returned to Sublessee at
the expiration of the Sublease.

  6. Suite Improvements. Sublessor will deliver and Sublessee accepts the
     -------------------
 premises in it's existing condition.

        7.  Right of Entry.  Sublessor shall have the right to enter the 
             --------------
Demised Premises for any reasonable purpose during business (hours) and upon 
reasonable notice (except in the event of an emergency), including to gain 
access to and egress from those portions of the Base Lease Premises or the 
Building not leased to Sublessee hereunder and to perform such functions as may 
be necessary or convenient for the maintenance and operation thereof and 
including to show the space to other prospective Sublessees.  Prior to the 
exercising its right of entry, Sublessor shall provide reasonable advance 
notice to Sublessee of such intended entry, and shall comply while in the 
Demised Premises with all reasonable safety and security measures instituted by 
Sublessee.

        8.  Compliance with Law.  Sublessee shall comply with all applicable
            -------------------
statutes, ordinances, rules, regulations, orders and directives of any 
governmental authority applicable to the Demised Premises or to Sublessee's use
or occupancy thereof and shall perform, at its own expenses, all obligations 
imposed thereby.

        9.  Release and Indemnity.
            ---------------------        

              A. Release. Sublessee hereby agrees that Sublessor shall not be
                 -------
liable for any loss or any damage to any property (including the property of
Sublessee, its officers, directors, employees, agents, customers,
concessionaires, vendors, contractors or invitees) or the death or injury of any
persons (including Sublessee, its officers; directors, employees, agents,
customers, concessionaires, vendors, contractors or invitees) occasioned by
theft, fire, acts of God, public enemy, injunction, governmental body or
authority, by other Sublessees of the Base Lease Premises or the Building or any
other matter beyond the control of Sublessor, or for any injury or damage or
inconvenience which may arise through repair or alteration of any part of the
Demised Premises or the Base Lease Premises or the Building, or failure to make
repairs, or for any cause whatsoever, except the negligence or willful
misconduct of Sublessor, or its officers, directors, employees, or agents or a
breach of the obligations of Sublessor hereunder.

              B.  Indemnity. Sublessee hereby releases and will defend indemnify
                  ---------
and hold harmless Sublessor and the Landlord, their respective officers,
directors, employees, agents, concessionaires, vendors and contractors (the
"Indemnified Parties") from and against any and all liability, claims,
penalties, fines, causes of action, suits, liens, losses, loss of use, damages,

<PAGE>
 
officers,  directors,  employees,  agents,  customers,  concessionaires,  
vendors, contractors or invitees.  The foregoing indemnification shall not apply

           A.    Coverage.  During the term of this Sublease, Sublessee, at its

Premises.

           C.    Waiver of Subrogation.  Sublessee, Sublessor and Landlord on 
                 ---------------------
behalf of themselves and their respective insurers, each hereby waives any claim
or right of recovery from each other, their officers, directors, employees, 
agents, concessionaires and contractors, for loss of or damage to its property 
or the property of others under its control, to the extent that such loss or 
damage is covered by valid insurance policies or is of the type which would be 
covered by "all risk" extended casualty coverage.  Each party shall provide 
notice of this waiver of subrogation to its insurers.

     11. Defaults.  The occurrence of any of the following shall constitute a
         --------

                 (i)   Sublessee fails to pay any sum as required hereunder and
such failure continues for ten (10) days following receipt of notice;

                 (ii)  Sublessee (i) fails to pay its bills to Sublessor or 
Landlord when due without just cause; or (ii) takes any steps leading to its 
cessation as a going concern or ceases or suspends operations for reasons other 
than a strike; or (iii) becomes insolvent or makes transfers in fraud of 
creditors or makes an assignment for the benefit of creditors; or (iv) files a 
petition for protection under any state or federal bankruptcy act or a trustee 
or receiver is appointed for all or substantially all of Sublessee's assets.

                                       5
<PAGE>
 
  12. Remedies Upon Default.  Upon the occurrence of an event of default
      ---------------------- 
hereunder, Sublessor may take any one or more of the following actions:

       (i)   Maintain this Sublease in full force and effect and recover any and
all rent and other monetary charges as they become due, without terminating
Sublessee's right to possession, regardless of whether Sublessee shall have
abandoned the Demised Premises. If Sublessor elects not to terminate this
Sublease, Sublessor shall have the right to attempt to relet the Premises on
behalf of Sublessee upon such conditions and for such a term and to do all acts
necessary to maintain or preserve the Demised Premises as Sublessor deems
reasonable and necessary, including the removal of all persons and property from
the Demised premises, without being deemed to have elected to terminate this
Sublease. Any property so removed may be disposed of or stored in a public
warehouse or elsewhere, at Sublessor's election, at the cost of and for the
account of Sublessee. Notwithstanding that Sublessor's fails to elect to
terminate this Sublease initially, Sublessor at any time thereafter may elect to
terminate this Sublease as a result of such previous and then existing default
of Sublessee;

      (ii)   Terminate this Sublease by written notice to Sublessee, in which 
event this Sublease shall be ended as to Sublessee and all persons holding under
Sublessee, and all of Sublessee's rights shall be forfeited and lapsed, as
fully as if this Sublease had expired by lapse of time. In such event, Sublessee
shall be required to vacate the Demised Premises immediately and surrender same
to Sublessor. If Sublessee fails to surrender the Demised Premises immediately
to Sublessor, Sublessor, without prejudice to any other remedy, may enter upon
and take possession of the Demised Premises and expel or remove Sublessee and
any part thereof, without being liable for prosecution or any other claim of
damages. In the event of termination in accordance with this provision, the
rental or any other sums payable by Sublessee pursuant to this Sublease that
have accrued hereunder but are unpaid shall be immediately due and payable by
Sublessee to Sublessor. In addition, Sublessee agrees to pay to Sublessor upon
demand the amount of all loss and damages which Sublessor may suffer by reason
of such termination, whether through inability to relet the premises on
satisfactory terms or otherwise, including reasonable court costs and attorney's
fees, in recovering possession of the Demised Premises or enforcing Sublessor
rights under this Sublease; (ii) all costs and charges for care of the Demised
Premises while vacant; (iii) all costs of restoring the Demised Premises to a
good condition; and (iv) all reasonable costs associated with Sublessor's
efforts to relet the Demised premises. In the event Sublessor relets the
Demised Premises for any portion of the remaining term of this Sublease,
Sublessee's rental payment obligation hereunder shall then be limited to the
difference between the rental payment Sublessor receives under such relet, if
any, and the rental amount Sublessee would have paid to Sublessor had this
Sublease not been terminated. The failure of Sublessor to relet the Demised
Premises or any part or parts thereof shall not release or effect Sublessee's
liability for damages hereunder;



                                       6







































  
<PAGE>
 
        (iii) Cure the default on the behalf of the Sublessee, in which event 
the Sublessee shall, upon demand by Sublessor, pay all sums expended by 
Sublessor in accomplishing such cure;

        (iv) Exercise any right available to Sublessor in law or in equity.
     
     13. Cumulative rights.  Sublessor's rights and remedies hereunder shall 
         -----------------
be cumulative and shall not be exclusive of one another, and Sublessor shall 
have the right to pursue any one or more of them.  Sublessor's acceptance of any
rent or other payments due hereunder or Sublessor's failure to take any action 
on account of a default if such default persists or is repeated, shall not be 
deemed a waiver of any default.  Sublessor's consent to any act by Sublessee 
requiring Sublessor's consent or approval shall not be deemed to waive or render
unnecessary Sublessor's consent or approval to any subsequent or similar acts by
Sublessee.

     14.  Surrender of Premises/Holding Over.  At the expiration or earlier 
          ----------------------------------
termination of this Sublease, Sublessee shall surrender the Demised Premises to 
Sublessor in good condition, broom clean, reasonable wear and tear excepted.  In
the event that Sublessee remains in possession after the expiration of or 
termination of this Sublease without a written agreement, or without Sublessee 
being engaged in active negotiations with Sublessor in good faith to renew or 
extend the term, the tenancy shall be deemed to be a month-to-month tenancy at a
monthly equal to one and one-half (1-1/2) times the sum of the Base Rent and 
Additional Rent(s) payable during the last month of the Term.  In the event 
Sublessee is actively negotiating with Sublessor to renew or extend the term, 
the month-to-month tenancy shall be at a rent equal to Sublessee's prorata share
of the Base Rent and Additional Rent(s) then payable by Sublessor to Landlord; 
such tenancy shall be subject to all terms and conditions of this Sublease.

     15.  Assignment and Sublease.  Sublessee shall not assign this Sublease or 
          -----------------------
any right hereunder or sublet the Demised Premises during the term of this 
Sublease, without the prior written consent of Sublessor.  In the event of an 
assignment or sublease, Sublessor shall be entitled to receive fifty percent 
(50%) of the excess of the rent and other sums payable by the Subtenant over the
amount of Rent payable hereunder for the Subleased Space.  Sublessor's 
acceptance of rent from any person other than Sublessee shall not be deemed to 
be a waiver of this provision.  Consent to one assignment or subletting shall 
not be deemed to be consent to any subsequent assignment or subletting.

     16.  Accord and Satisfaction.  No payment or receipt by Sublessor of a 
          -----------------------
lesser amount than the rent or other charges herein stipulated shall be deemed 
to be other than on account of the rent or such charges.  Further, no 
endorsement or statement on any check or any letter accompanying any check shall
be deemed to be an accord and satisfaction.  Sublessor may accept such check or 
payment without prejudice to Sublessor's right to recover the balance of such 
rent or other charges or pursue any other remedy provided in this Sublease.

     17.  Entire Agreement.  This Sublease constitutes the complete agreement of
          ----------------
the parties with respect to the subject matter hereof and supersedes all 
previous agreements, representations and understandings concerning the same, 
whether written


                                       7
<PAGE>
 
or oral.  The provisions of the Sublease may be modified, amended or waived only
by a written instrument, executed by Sublessor and Sublessee.

          18.  Approval by Landlord.  This Sublease is conditional upon written
               ---------------------
consent being obtained from the Landlord.  In the event the Landlord does not 
give its consent, either the undersigned parties may, at its option, rescind

                      --------------------------------------------------------
                      INC., A DELAWARE CORPORATION (hereinafter called
                      ----------------------------

                      Use and for no other use or purpose without the prior
                      written consent of Landlord. No increase in occupant
                      density of the Leased Premises shall be made which shall
                      add to the burden of such use of the Building as
                      determined by Landlord without the prior written consent
                      of Landlord.

                      except as otherwise provided herein or in any exhibit or
                      addendum hereto, shall continue in full force until the
                      Term Expiration Date. If the Premises are not delivered by
                      Landlord by the Scheduled Term Commencement Date for any
                      reason, Landlord shall not be liable to Tenant for any
                      loss or damage resulting from such delay. The Term
                      Commencement Date shall be the first day of the calendar
                      month next following the earlier of (i) the day when the

                      Information or to such other firm or to such other place
                      as Landlord may from time to time designate in writing by
                      notice given as herein provided. Rent for the first month
                      of the Term shall be paid by Tenant upon execution of this
                      Lease. If the obligation for payment of Rent commences on
                      other than the first day of a month as provided in
                      paragraph 3(a), then Rent provided for such partial month

                      terminates on other than the last day of a calendar
                      month, then the Rent provided for such partial month shall
                      be prorated and the prorated installment shall be paid on
                      the first day of the calendar month next preceding the
                      date of termination.

RESTRICTIONS       5.      Tenant shall not do or permit anything to be done
ON USE                in or about the Premises which will in anyway obstruct
                      or interfere with the rights of other tenants or occupants
                      of the Building or injure or annoy them, nor use or allow
                      the Premises to be used for any improper, immoral,
                      unlawful or objectionable purpose, nor shall Tenant cause
                      or maintain or permit any nuisance in, on or about the
                      Premises. Tenant shall not commit or suffer the commission
                      of any waste in, on or about the Premises.

            

COMPLIANCE         6.      Tenant shall not use the Premises or permit anything 
WITH LAWS             to be done in or about the Premises which will in any way
                      conflict with any law, statute, ordinance or governmental
                      rule or regulation now in force or which may hereafter be
                      enacted or promulgated. Tenant shall not do or permit
                      anything to be done on or about the Premises or bring or
                      keep anything therein which will in any way increase the
                      rate of any insurance upon the Building or any of its
                      contents or cause a cancellation of said insurance or
                      otherwise affect said insurance in any manner, and Tenant
                      shall at its sole cost and expense promptly comply with
                      all laws, statutes, ordinances and governmental rules,
                      regulations or requirements now in force or which may
                      hereafter be in force and with the requirements of any
                      board of fire underwriters or other similar body now or
                      hereafter constituted relating to or affecting the
                      condition, use or occupancy of the Premises, excluding
                      structural changes not related to or affected by
                      alterations or improvements made by or for Tenant or
                      Tenant's acts. The judgment of any court of competent
                      jurisdiction or the admission of Tenant in any actions
                      against Tenant, whether Landlord be a party thereto or
                      not, that Tenant has so violated any such law, statute,
                      ordinance, rule, regulation or requirement, shall be
                      conclusive of such violation as between Landlord and
                      Tenant.

ALTERATIONS        7.      Tenant shall not make or suffer to be made any 
                      alterations, additions or improvements in, on or to the
                      Premises or any part thereof without the prior written
                      consent of Landlord; and any such alterations, additions
                      or improvements in, on or to said Premises, except for
                      Tenant's movable furniture and equipment, shall
                      immediately become Landlord's property and, at the end of
                      the Term, shall remain on the Premises without
                      compensation to Tenant. In the event Landlord consents to
                      the making of any such alteration, addition or improvement
                      by Tenant, the same shall be made by Tenant, at Tenant's
                      sole cost and expense, in accordance with plans and
                      specifications approved by Landlord, and any contractor
                      or person selected by Tenant to make the same must first
                      be approved in writing by Landlord.
                      
                      Notwithstanding the foregoing, at Landlord's option, all
                      or any portion of the alteration, addition or improvement,
                      work shall be performed by Landlord for Tenant's account
                      and Tenant shall pay Landlord's estimate of the cost
                      thereof (including a reasonable charge for Landlord's
                      overhead and profit) prior to commencement of the work
                      Overhead and profit allowances shall total fifteen percent
                      (15%). Upon the expiration or sooner termination of the
                      Term, Tenant shall upon demand by Landlord, at Tenant's
                      sole cost and expense, with all due diligence remove all
                      those alterations, additions or improvements made by or
                      for the account of Tenant, designated by Landlord to be
                      removed, and Tenant shall with all due diligence, at its
                      sole cost and expense, repair and restore the Premises to
                      their original condition. At Landlord's election and
                      notwithstanding the foregoing, however, Tenant shall pay

                      constitute an assignment subject to the terms of this
                      paragraph 10.

                      (a) In the event that Tenant should desire to sublet the

                      Landlord with written notice of such desire at least
                      thirty (30) in advance of the date on which Tenant desires

                      of thirty (30) days following receipt of such notice

                      elects either (i) to terminate this lease as to the space
                      so affected as of the date so specified by Tenant, in
                      which event Tenant shall be relieved of all further
                      obligations hereunder as to such space from and after that
                      date, or (ii) to permit Tenant to sublet such space,

                      proposed sublessee by Landlord which said consent shall

                      notify Tenant in writing of its election within said
                      thirty (30) day period, Landlord shall be deemed to have
                      waived option (i) above, but written approval of the
                      proposed sublessee shall not constitute a termination of
                      this Lease. In exercising its right of consent to a
                      sublessee it shall be reasonable for Landlord to withhold
                      consent to any sublessee who (aa) does not agree to assume
                      the obligations of the Lease with respect to the space to
                      be so sublet, (bb) does not agree to utilize the space so
                      sublet for the Permitted Use, (cc) is of unsound financial
                      condition as determined by Landlord, or (dd) will, in
                      Landlord's opinion increase the occupant density in the
                      Leased Premises. If Tenant proposes to sublease less than
                      all of the Premises, election by Landlord of termination
                      of this Lease with respect to the remainder of the space,
                      the Rent and Tenant's Proportionate Share of Operating
                      Expenses and taxes shall be adjusted on a pro rata basis
                      to reflect the reduction in Net Rentable Area of the
                      Premises as retained by Tenant. This Lease as so amended
                      shall continue thereafter in full force and effect and
                      reference herein to the Premises shall mean that portion
                      thereof as to which the Lease has not been terminated.

                      (b) Tenant shall not enter into any other transaction
                      subject to this paragraph 10 without Landlord's prior
                      written consent which said consent shall not be
                      unreasonably withheld. It shall be reasonable for Landlord
                      to withhold consent to any proposed transaction described
                      in this paragraph 10 on any of the grounds specified in
                      paragraph 10(a) with respect to sublessees or any other
                      reasonable grounds.

                      (c) Any rent or other consideration realized by Tenant
                      under any such sublease or assignment to which Landlord
                      has consented hereunder, in excess of the Rent payable
                      hereunder, after amortization of the reasonable cost of
                      the improvements over the remainder of the Term for which
                      Tenant has paid and reasonable subletting and assignments
                      costs, shall be divided and paid fifty percent (50%) to
                      Tenant.

                      (d) Any subletting hereunder by Tenant shall not result in
                      Tenant being released or discharged from any liability
                      under this lease. Any purported assignment, subletting or
                      other transaction to which paragraph 10 applies, which
                      occurs contrary to the provisions hereof, shall be void.
                      Landlord's consent to any assignment, subletting or other
                      transaction to which this paragraph 10 applies shall not
                      release Tenant from any of Tenant's obligations hereunder
                      or constitute a consent with respect to any subsequent
                      transaction to which this paragraph applies.

                  a waiver of subrogation by the carrier which conforms to the
                  provisions of this paragraph.

SERVICES AND
   UTILITIES  13. (a) Landlord shall maintain the public and common areas of the
                  Building, including lobbies, stairs, elevators, corridors and
                  restrooms, the windows in the Building, the mechanical,
                  plumbing and electrical equipment serving the Building, and
                  the structure itself, in reasonably good order and condition
                  except for damage occasioned by the act of Tenant, which
                  damage shall be repaired by Landlord at Tenant's expense.

                  (b) Provided Tenant shall not be in default hereunder, and
                  subject to the provisions elsewhere herein contained and to
                  the rules and regulations of the Building, Landlord shall
                  furnish to the Premises during ordinary business hours of
                  generally recognized business days, to be determined by
                  Landlord (but exclusive, in any event, of Saturdays, Sundays
                  and legal holidays), water and electricity suitable for the
                  Permitted Uses of the Premises, heat and air conditioning
                  required in Landlord's judgment for the comfortable use and
                  occupation of the Premises for the Permitted Uses, janitorial
                  services during the times and in the manner that such services
                  are, in Landlord's judgment, customarily furnished in
                  comparable office buildings in the immediate market area, and
                  elevator service which shall mean service either by
                  nonattended automatic elevators or elevators with attendants
                  or both, at the option of Landlord. Landlord shall have no
                  obligation to provide additional or after-hours heating or air
                  conditioning, but if Landlord elects to provide such services
                  at Tenant's request, Tenant shall pay to Landlord a reasonable
                  charge for such services as determined by Landlord. Tenant
                  agrees to keep and cause to be kept closed all window covering
                  when necessary because of the sun's position, and Tenant also
                  agrees at all times to cooperate fully with Landlord and to
                  abide by all the regulations and requirements which Landlord
                  may prescribe for the proper functioning and protection of
                  heating,

                      ventilating and air conditioning systems. Wherever heat-
                      generating machines, excess lighting or equipment are used
                      in the Premises which affect the temperature otherwise
                      maintained by the air conditioning system, Landlord
                      reserves the right to install supplementary air
                      conditioning units in the Premises, and the cost thereof
                      including the cost of installation and the cost of
                      operation and maintenance thereof, shall be paid by Tenant
                      to Landlord upon demand by Landlord. See Addendum #6
                      attached hereto and made a part hereof.

                      (c)  Tenant shall not without the written consent of
                      Landlord use any apparatus or device in the Premises,
                      including without limitation, electronics data processing
                      machines, punch card machines, and machines using excess
                      lighting or using current in excess of that which is
                      determined by Landlord as reasonable and normal for the
                      Permitted Use or which will in any way increase the amount
                      of electricity or water usually furnished or supplied for
                      the Permitted Uses of the Premises; nor connect with
                      electric current except through existing electrical
                      outlets in the Premises or water pipes, any apparatus or
                      device for the purposes of using electrical current or
                      water. If Tenant shall require water or electric current
                      or any other resource in excess of that usually furnished
                      or supplied for the Permitted Use of the Premises, Tenant
                      shall first procure the consent of Landlord which Landlord
                      may refuse, to the use thereof, and Landlord may cause a
                      special meter to be installed in the Premises so as to
                      measure the amount of water, electrical current or other
                      resource consumed for any such other use. Tenant shall pay
                      directly to Landlord as an addition to and separate from
                      payment of Basic Operating Cost the cost of all such
                      energy, utility service and meters (and of installation,
                      maintenance and repair thereof). Landlord may add to the
                      metered charge a recovery of additional expense incurred
                      in keeping account of the water, electric current or other
                      resource so consumed. Landlord shall not be liable for any
                      damages directly or indirectly resulting from, nor shall
                      the Rent herein reserved be abated by reason of (i) the
                      installation, use or interruption of use of any equipment
                      in connection with the furnishing of any of the foregoing
                      utilities and services, (ii) failure to furnish or delay
                      in furnishing any such utilities or services when such
                      failure or delay is caused by acts of God or the elements,
                      labor disturbances of any character, any other accident or
                      other conditions beyond the reasonable control of
                      Landlord, or by the making of repairs or improvements to
                      the Premises or to the Building, or (iii) the limitation,
                      curtailment, rationing or restriction on use of water,
                      electricity, gas or any other form of energy or any other
                      service or utility whatsoever serving the Premises or the
                      Building. Landlord shall be entitled to cooperate
                      voluntarily and in a reasonable manner with the efforts of
                      national, state or local governmental agencies or utility
                      suppliers in reducing energy or other resource
                      consumption. The obligation to make services available
                      hereunder shall be subject to the limitations of any such
                      voluntary, reasonable program.

                      (d)  Any sums payable under this paragraph 13 shall 
                      constitute Additional Rent hereunder.

     ESTOPPEL     14.    Within ten (10) days following any written request 
  CERTIFICATE         which Landlord may make from time to time, Tenant shall
                      execute and deliver to Landlord a certificate
                      substantially in the form attached hereto as Exhibit D and
                      made a part hereof, indicating thereon any exceptions
                      thereto which may exist at that time. Failure by Tenant to
                      execute and deliver such certificate shall constitute an
                      acceptance of the Premises and acknowledgment by Tenant
                      that the statements included in Exhibit D are true and
                      correct without exception. Landlord and tenant intend that
                      any statements included in Exhibit D are true and correct
                      without exception. Landlord and Tenant intend that any
                      statement delivered pursuant to this paragraph may be
                      relied upon by any mortgagee, beneficiary, purchaser or
                      prospective purchaser of the Building or any interest
                      therein. Landlord shall have the right to substitute for
                      the attached exhibit D a certificate in form required by
                      Landlord's mortgagee or provider of financing.
     SECURITY
      DEPOSIT     15.    Concurrently with execution hereof, Tenant has paid to 
                      Landlord the Security Deposit in the amount stated on the
                      Basic Lease Information sheet as security for the full and
                      faithful performance of Tenant's obligations under this
                      Lease. Upon expiration of the Term or earlier termination
                      hereof, the Security Deposit shall be returned to Tenant,
                      reduced by such amounts as may be required by Landlord to
                      remedy defaults on the part of Tenant in the payment of
                      Rent, to repair damages to the Premises caused by Tenant
                      and to clean the Premises. Landlord shall hold the
                      Security Deposit for the foregoing purposes in accordance
                      with the provisions of all applicable law.
 SUBSTITUTION
                  16.    At any time after execution of this Lease, Landlord may
                      substitute for the Premises other premises in the Building
                      (the "New Premises") upon not less than ninety (90) days
                      prior written notice, in which event the new Premises
                      shall be deemed to be the Premises for all purposes
                      hereunder, provided, however, that:

                      (a) The Net Rentable Area in the Premises is less than 
                      five thousand (5,000) square feet;
                      (b) The New Premises shall be similar in area and in 
                      appropriateness for Tenant's purposes;
                      (c) Any such substitution is effected for the purpose of
                      accommodating a tenant who will occupy all or a
                      substantial portion of the Net Rentable Area of the floor
                      on which the Premises are located; and 
                      (d) If Tenant is occupying the Premises at the time of
                      such substitution, Landlord shall pay the expense of
                      moving Tenant, its property and equipment to the New
                      Premises and shall, at its sole cost, improve the New
                      Premises with improvements substantially similar to those
                      Landlord has committed to provide or has provided in the
 HOLDING OVER         Premises.

                  17.    If Tenant shall retain possession of the Premises or 
                      any part thereof without Landlord's consent following the
                      expiration of the Term or sooner termination of this Lease
                      for any reason, then Tenant shall pay to Landlord for each
                      day of such retention double the amount of the daily
                      rental for the last period prior to the date of such
                      expiration or termination. Tenant shall also indemnify and
                      hold Landlord harmless from any loss or liability
                      resulting from delay by Tenant in surrendering the
                      Premises, including, without limitation, any claims made
                      by any succeeding tenant founded on such delay.
                      Alternatively, if Landlord gives notice to Tenant of
                      Landlord's election thereof, such holding over shall
                      constitute renewal of this Lease for a period from month
                      to month whichever shall be specified in such notice.
                      Acceptance of Rent by Landlord following expiration or
                      termination shall not constitute a renewal of this Lease,
                      and nothing contained in this paragraph shall waive
                      Landlord's right of reentry or any other right. Unless
                      Landlord exercises the option hereby given to it, Tenant
                      shall be only a Tenant at sufferance, whether or not
                      Landlord accepts any Rent from Tenant while Tenant is
SUBORDINATION         holding over without Landlord's written consent.

                  18.    Without the necessity of any additional document being 
                      executed by Tenant for the purpose of effecting a
                      subordination, this Lease shall be subject and subordinate
                      at all times to: (a) all ground leases or underlying
                      leases which may now exist or hereafter be executed
                      affecting the Building or the land upon which the Building
                      is situated or both, and (b) the lien of any mortgage or
                      deed of trust which
<PAGE>
 
 
                 may now exist or hereafter be executed in any amount for which
                 said Building, land, ground leases or underlying leases, or
                 Landlord's interest or estate in any of said items, is
                 specified as security. Notwithstanding the foregoing, Landlord
                 shall have the right to subordinate or cause to be subordinated
                 any such ground leases or underlying leases or any such liens
                 to this Lease. In the event that any ground lease or underlying
                 lease terminates for any reason or any mortgage or deed of
                 trust is foreclosed or a conveyance in lieu of foreclosure is
                 made for any reason, Tenant shall, notwithstanding any
                 subordination, attorn to and become the Tenant of the successor
                 in interest to Landlord at the option of such successor in
                 interest. Tenant shall execute and deliver, upon demand by
                 Landlord and in the form requested by Landlord, any additional
                 documents evidencing the priority or subordination of this
                 Lease with respect to any such ground leases or underlying
                 leases or the lien of any such mortgage or deed of trust.
                 Tenant hereby irrevocably appoints Landlord as attorney-in-
                 fact of Tenant to execute, deliver and record any such
                 documents in the name and on behalf of Tenant. At the request
                 of Landlord, Tenant shall provide to Landlord its current
                 financial statement or other information disclosing financial
                 worth which Landlord shall use solely for purposes of this
                 Lease and in connection with the ownership, management and
                 disposition of the property subject hereto.

    RULES AND 19.    Tenant shall faithfully observe and comply with the rules
  REGULATIONS    and regulations printed on or annexed to this Lease and all
                 reasonable modifications thereof and additions thereto from
                 time to time put into effect by Landlord. Landlord shall not be
                 responsible to Tenant for the non-compliance by any other
                 tenant or occupant of the Building with any of the rules and
                 regulations.

RE-ENTRY BY   20.    Landlord reserves and shall with reasonable advance notice
   LANDLORD      except in emergencies have the right to reenter the premises to
                 inspect the same, to supply janitor service and any other
                 service to be provided by Landlord to Tenant hereunder, to show
                 the Premises to prospective purchasers, mortgagees or tenants,
                 to post notices of nonresponsibility and to alter, improve or
                 repair the Premises and any portion of the Building, without
                 abatement of Rent, and may for that purpose erect, use and
                 maintain scaffolding, pipes, conduits and other necessary
                 structures in and through the Premises where reasonably
                 required by the character of the work to be performed: provided
                 that entrance to the Premises shall not be blocked thereby, and
                 further provided that the business of Tenant shall not be
                 interfered with unreasonably. Tenant waives any claim for
                 damages for any injury or inconveniences to or interference
                 with Tenant's business, any loss of occupancy or quiet
                 enjoyment of the Premises, and any other loss occasioned
                 thereby, Landlord shall at all times have and retain a key with
                 which to unlock all of the doors in, upon and about the
                 premises, excluding Tenant's vaults and safes or special
                 security areas (designated in advance), and Landlord shall have
                 the right to use any and all means which Landlord may deem
                 necessary or proper to open said doors in an emergency, in
                 order to obtain entry to any portion of the Premises, and any
                 entry to the Premises or portions thereof obtained by Landlord
                 by any of said means, or otherwise, shall not be construed to
                 be a forcible or unlawful entry into, or a detainer of, the
                 Premises, or an eviction, actual or constructive, of Tenant
                 from the Premises or any portions thereof. Landlord shall also
                 have the right at any time, without the same constituting an
                 actual or constructive eviction and without incurring any
                 liability to Tenant thereof, to change the arrangement and/or
                 location of entrances or passageways, doors and doorways, and
                 corridors, elevators, stairs, toilets or other public parts of
                 the Building and to change the name, number or designation by
                 which the Building is commonly known.
DEFAULT BY
    TENANT    21.(a) Events of Default: The occurrence of any of the following 
                 shall constitute an event of default on the part of Tenant:

                 (1)  Abandonment. Abandonment of the Premises for a continuous
                      period in excess of five (5) business days. Tenant waives
                      any right to notice Tenant may have under Section 1951.3
                      of the Civil Code of the State of California, the terms of
                      this subsection (a) being deemed such notice to Tenant as
                      required by said Section 1951.3:

                 (2)  Nonpayment of Rent. Failure to pay any installment of Rent
                      due and payable hereunder (or failure to pay any other
                      amount required to be paid hereunder, all such obligations

                      such longer period as Landlord determines to be necessary
                      to remedy such default, provided that Tenant shall
                      continuously and diligently pursue such remedy at all time

                   without terminating this Lease, may exercise all of the

                   Lease pursuant to the provisions of paragraph 21 (b)(2)
                   hereof, Landlord shall have all the rights and remedies of a
                   landlord provided by Section 1951.2 of the Civil Code of the
                   State of California, or successor code section. Upon such
                   termination, in addition to any other rights and remedies to
                   which Landlord may be entitled under applicable law, Landlord
                   shall be entitled to recover from Tenant: (i) the worth at
                   the time of award of the unpaid Rent and other amounts which
                   had been earned at the time of termination; (ii) the worth at
                   the time of award of the amount by which the unpaid Rent
                   which would have been earned after termination until the time
                   of award exceeds the amount of such Rent loss that the Tenant
                   proves could have been reasonably avoided; (iii) the worth
                   at the time of award of the amount by which the unpaid Rent
                   for the balance of the Term after the time of award exceeds
                   the amount of such Rent loss that the Tenant proves could be
                   reasonably avoided; and (iv) any other amount necessary to
                   compensate Landlord for all the detriment proximately caused
                   by Tenant's failure to perform its obligations under this
                   Lease or which, in the ordinary course of things, would be
                   likely to result therefrom. The "worth at the time of award"
                   of the amounts referred to in (i) and (ii) shall be computed
                   with interest at the lesser of eighteen percent (18%) per
                   annum or the maximum rate allowed by law. The "worth at the
                   time of award" of the amount referred to in (iii) shall be
                   computed by reference to competent appraisal evidence or the
                   formula prescribed by using the lowest discount rate 
                   permitted under applicable law.

               (d) Computation Of Rent For Purposes Of Default.

                   For purposes of computing unpaid Rent which would have
               accrued and become payable under this Lease pursuant to the
               provisions of paragraph 21(c) unpaid Rent shall consist of the
               sum of

               (1) the total Basic Rent for the balance of the Term then
                   remaining (with the amount of Basic Rent to be determined by
                   reference to fair rental value being the subject of proof by
                   competent evidence), plus

               (2) a computation of the excess of Gross Rent (the term "Gross
                   Rent" meaning the sum of (i) rental adjustments payable
                   pursuant to paragraph 29 and (ii) Basic Rent) over Basic Rent
                   for the balance of the Term then remaining ("Excess Gross
                   Rental"), the assumed excess Gross Rental for the calendar
                   year of the default and each future calendar year in the Term
                   to be equal to the Excess Gross Rental for the calendar year
                   prior to the year in which default occurs compounded at a per
                   annum rate equal to the mean average rate of inflation for
                   the preceding five (5) calendar years as determined by the
                   United States Department of Labor, Bureau of Labor Statistics
                   Consumer Price Index (All Urban Consumers) for the
                   Metropolitan Area or Region of which San Francisco,
                   California is a part.

               (e) Late Charge. In addition to its other remedies, Landlord
               shall have the right without notice or demand to add to the
               amount of any payment required to be made by Tenant hereunder,
               and which is not paid on or before the date the same is due, an
               amount equal to five percent (5%) of the delinquency for each
               month or portion thereof that the delinquency remains outstanding
               to compensate Landlord for the loss of the use of the amount not
               paid and the administrative costs caused by the delinquency, the
               parties agreeing that Landlord's damage by virtue of such
               delinquencies would be difficult to compute and the amount stated
               herein represents a reasonable estimate thereof.

               (f) Remedies Cumulative. All right, privileges and elections or
               remedies of the parties are cumulative and not alternative to the
               extent permitted by law and except as otherwise provided herein.

                        proportionate reduction shall be based upon the extent  
                        to which the making of such repairs to be made hereunder
                        by Landlord shall interfere with the business carried on

                        to which said damage interfered with the business
                        carried on by Tenant in the Premises, and Tenant shall

                   appropriated under the power of eminent domain or conveyed in
                   lieu thereof, either party shall have the right to terminate
                   this Lease at its option. If any part of the Building shall
                   be taken or appropriated under power of eminent domain or
                   conveyed in lieu thereof, Landlord may terminate this Lease
                   at its option. In either of such events, Landlord shall
                   receive (and Tenant shall assign to Landlord upon demand from
                   Landlord) any income, rent, award or any interest therein
                   which may be paid in connection with the exercise of such
                   power of eminent domain, and Tenant shall have no claim
                   against Landlord for any part of the sums paid by virtue of
                   such proceedings, whether or not attributable to the value of
                   the unexpired Term. If a part of the Premises shall be so
                   taken or appropriated or conveyed and neither party hereto
                   shall elect to terminate this Lease and the Premises have
                   been damaged as a consequence of such partial taking or
                   appropriation or conveyance, Landlord shall restore the
                   Premises continuing under this Lease at Landlord's cost and
                   expense; provided, however, that Landlord shall not be
                   required to repair or restore any injury or damage to the
                   property of Tenant or to make any repairs or restoration of
                   any alterations, additions, fixtures or improvements
                   installed on the Premises by or at the expense of Tenant.
                   Thereafter, the Rent for the remainder of the Term shall be
                   proportionately reduced, such reduction to be based upon the
                   extent to which the partial taking or appropriation or
                   conveyance shall interfere with the business carried on by
                   Tenant in the Premises. Notwithstanding anything to the
                   contrary contained in this paragraph, if the temporary use or
                   occupancy of any part of the Premises shall be taken or
                   appropriated under power of eminent domain during the Term,
                   this Lease shall be and remain unaffected by such taking or
                   appropriation and Tenant shall continue to pay in full all
                   Rent payable hereunder by Tenant during the Term; in the
                   event of any such temporary appropriation or taking, Tenant
                   shall be entitled to receive that portion of any award which
                   represents compensation for the use of or occupancy of the
                   Premises during the Term, and Landlord shall be entitled to
                   receive that portion of any award which represents the cost
                   of restoration of the Premises and the use and occupancy of
                   the Premises after the end of the Term. SALE BY LANDLORD AND

                   or conditions, express or implied, herein contained in favor
                   of Tenant, and in such event Tenant agrees to look solely to
                   the responsibility of the successor in interest of Landlord
                   in and to this Lease. This Lease shall not be affected by any
                   such sale and Tenant agrees to attorn to the purchaser or
                   assignee. Tenant shall look solely to Landlord's interest in
                   the Building for recovery of any judgment from Landlord.
                   Landlord, or if Landlord is a partnership, its partners
                   whether general or limited, or if Landlord is a corporation,
                   its directors, officers or shareholders, shall never be
                   personally liable for any such judgment. 

   RIGHT OF 
LANDLORD TO     25.     All convenants and agreements to be performed by
    PERFORM        Tenant under any of the terms of this Lease shall be
                   performed by Tenant at Tenant's sole cost and expense and
                   without any abatement of Rent. If Tenant shall fail to pay
                   any sum of money, other than Rent, required to be paid by it
                   hereunder or shall fail to perform any other act on its part
                   to be performed hereunder, and such failure shall continue
                   for ten (10) days after notice thereof by Landlord, Landlord
                   may, but shall not be obligated to do so, and without waiving
                   or releasing Tenant from any obligations of the Tenant, make
                   any such payment or perform any such act on the Tenant's part
                   to be made or performed. All sums so paid by Landlord and all
                   necessary incidental costs together with interest thereon at
                   the rate of eighteen percent (18%) per annum or the maximum
                   rate permitted by law, whichever is less per annum from the
                   date of such payment by the Landlord shall be payable as
                   Additional Rent to Landlord on demand, and Tenant covenants
                   to pay such sums, and Landlord shall have, in addition to any
                   other right or remedy of Landlord, the same right and
                   remedies in the event of the nonpayment thereof by Tenant as
SURRENDER OF       in the case of default by Tenant in the payment of the Rent.
    PREMISES
               26. (a) Tenant shall, at least ninety (90) days before the last
                   day of the Term, give to Landlord a written notice of
                   intention to surrender the Premises on that date, but nothing
                   contained herein shall be construed as an extension of the
                   Term or as consent of Landlord to any holding over by Tenant.

                   (b) At the end of the term or any renewal thereof or other
                   sooner termination of this Lease, Tenant shall peaceably
                   deliver up to Landlord possession of the Premises, together
                   with all improvements, fixtures or ordinary wear additions
                   thereto by whomsoever made, in the same condition as
                   received, or first installed, damage by fire, earthquake, act
                   of God, ordinary wear and tear or the elements alone
                   excepted. Tenant may, upon the termination of this Lease,
                   remove all movable furniture and equipment belonging to
                   Tenant, at Tenant's sole cost, title to which shall be in
                   Tenant until such termination, repairing any damage caused by
                   such removal. Property not so removed shall be deemed
                   abandoned by the Tenant, and title to the same shall
                   thereupon pass to Landlord.

                   (c) The voluntary or other surrender of this Lease by Tenant,
                   or a mutual cancellation thereof, shall not work a merger and
                   shall, at the option of Landlord, terminate all or any
      WAIVER       existing subleases or subtenancies or may, at the option of
                   Landlord, operate as an assignment to it of any or all such
                   subleases or subtenancies.

               27.     If either Landlord or Tenant waives the performance of
                   any term, covenant or condition contained in this Lease, such
                   waiver shall not be deemed to be a waiver of any subsequent
                   breach of the same or any other term, covenant or condition
                   contained herein. The acceptance of Rent by Landlord shall
                   not constitute a waiver of any preceding breach by Tenant of
                   any term, covenant or condition of this Lease, regardless of
                   Landlord's knowledge of such preceding breach at the time
                   Landlord accepted such Rent. Failure by Landlord to enforce
                   any of the terms, convenants or conditions of this Lease for
                   any length of time shall not be deemed to waive or to
                   decrease the right of Landlord to insist thereafter upon
                   strict performance by Tenant. Waiver by Landlord of any term,
                   covenant or condition contained in this lease may only be
                   made by a written document signed by Landlord.

                       (2) "Estimated Basic Operating Cost" for any particular 
                       year shall mean Landlord's estimate of the Basic
                       Operating Cost for such calendar year made prior to
                       commencement of such calendar year as hereinafter
                       provided. Landlord shall have the right from time to time
                       to revise its fiscal year and interim accounting periods
                       so long as the periods as so revised are reconciled with
                       prior periods in accordance with generally accepted
                       accounting principles applied in a consistent manner.

                       (3) "Basic Operating Cost Adjustment" shall mean the
                       difference between Basic Operating Cost and Estimated
                       Basic Operating Cost for any calendar year determined as
                       hereinafter provided.

                       (B) Payment Of Estimated Operating Cost.

                           During December of each calendar year during the
                       Term, or as soon thereafter as practicable, Landlord
                       shall give Tenant written notice of the Estimated Basic
                       Operating Cost for the ensuing calendar year. The
                       Estimated Basic Operating Cost for the calendar year in
                       which the Scheduled Term Commencement Date falls is set
                       forth in the Basic Lease information sheet. Tenant shall
                       pay Tenant's Proportionate Share of the Estimated Basic
                       Operating Costs with Installments of Basic Rent required
                       to be paid pursuant to paragraph 3 above for the calendar
                       year to which the estimate applies in monthly
                       installments on the first day of each calendar month
                       during such year, in advance. Such payment shall be
                       construed to be Rent for all purposes hereof. If at any
                       time during the course of a calendar year, Landlord
                       determines that Basic Operating Cost will apparently vary
                       from the then Estimated Basic Operating Cost by more than
                       five percent (5%), Landlord may, by written notice to
                       Tenant, revise the Estimated Basic Operating Cost for the
                       balance of such calendar year and Tenant shall pay Tenant
                       Proportionate Share of the Estimated Basic Operating Cost
                       as so revised for the balance of the then current
                       calendar year on the first day of each calendar month
                       thereafter, such revised installment amounts to be Rent
                       for all purposes hereof.

                       (C) Computation Of Basic Operating Cost Adjustment.

                           Within one hundred twenty (120) days after the 
                       end of each fiscal year as determined by Landlord or as
                       soon thereafter as practicable, Landlord shall deliver to
                       Tenant a statement of Basic Operating Cost for the fiscal
                       year just ended, accompanied by a computation of Basic
                       Operating Cost Adjustment. If such statement shows that
                       Tenant's payment based upon Estimated Basic Operating
                       Cost is less than Tenant's Proportionate Share of Basic
                       Operating Cost, then Tenant shall pay the difference
                       within twenty (20) days after receipt of such statement,
                       such payment to constitute additional rent hereunder. If
                       such statement shows that Tenant's payments of Estimated
                       Basic Operating Cost exceed Tenant's Proportionate Share
                       of Basic Operating Costs, then (provide that Tenant is
                       not in default under this Lease), Tenant shall receive a
                       credit for the amount of such payment against Tenant's
                       obligation for payment of Tenant's Proportionate Share of
                       Estimated Basic Operating Cost next becoming due
                       hereunder. If this Lease has been terminated or the Term
                       hereof has expired prior to the date of such statement,
                       then the Basic Operating Cost Adjustment shall be paid by
                       the appropriate party within twenty (20) days after the
                       date of delivery of the statement.

                       (D) Net Lease. This shall be a net lease and Base Rent
                       shall be paid to Landlord absolutely net of all costs and
                       expenses. The provisions for payment of Basic Operating
                       Cost by means of periodic payments of Tenant's
                       Proportionate Share of Estimated Basic Operating Cost and
                       the Basic Operating Cost Adjustment are intended to pass
                       on to Tenant and reimburse Landlord for all cost and
                       expenses of the nature described in paragraph 29(a)(1)
                       above incurred in connection with ownership and operation
                       of the Building and such additional facilities now and in
                       subsequent years as may be determined by Landlord to be
                       necessary to the Building.

                       (e) Tenant Audit. Tenant shall have the right, at
                       Tenant's expense and upon not less than forty-eight (48)
                       hours prior written notice to Landlord to review at
                       reasonable times Landlord's books and records for any
                       calendar year a portion of which falls within the Term
                       for purposes of verifying Landlord's calculation of Basic
                       Operating cost and Basic Operating Cost Adjustment. In
                       the event that Tenant shall dispute the amount set forth
                       in any statement provided by Landlord under paragraph
                       2g(c) above, Tenant shall have the right not later than
                       twenty (20) days following the receipt of such statement,
                       and upon condition that Tenant shall first deposit with
                       Landlord the full amount in dispute, to cause Landlord's
                       books and records with respect to such calendar year to
                       be audited by certified public accountants selected by
                       Tenant subject to Landlord's reasonable right of
                       approval. The Basic Operating Cost Adjustment shall be
                       appropriately adjusted on the basis of such audit. If
                       such audit discloses a liability for a refund or credit

              to control and prevent access thereto by all persons whose

              and its Tenants, provided that nothing herein contained shall be 
              construed to prevent such access to persons with whom any Tenant
